WIT Research Day 2011 Book of Abstracts
Foreward
Welcome to the book of abstracts compiled from the presentations made by staff and
students during the WIT Research Day 2011. The last 10 years have been a period
of transformation within the third level research community and in particular
within the Institute of Technology sector. Waterford Institute of Technology‘s
Institutional Strategy recognises the special role it has in the economic, social and
cultural development of the South East region and beyond. The tradition of
excellence in teaching is well established in the Institute with its graduates in key
leadership roles in industry and public services. At the heart of the WIT culture is
the spirit of innovation and responsiveness to the needs of its stakeholders.
The emergence of the knowledge economy and the subsequent requirement for
Ireland to reposition itself up the economic value chain has placed important
challenges on third level educational establishments. Responding to these
challenges regionally and nationally the Institute has established itself as a research
led institution. Its research community is networked with leading research groups
not only in Ireland but across the 5 Continents. This has led to the creation of a
dynamic 4th level education environment with approximately 180 research students
registered for Masters or PhD‘s. The community of academic researchers,
postdoctoral fellows and postgraduate students is a truly multicultural community
with students and staff from around the world. Our research work is published in
some of the world leading journals and presented at leading international
conferences. This ensures that the outcomes of our research activities are
benchmarked against the best in the world. Our ability to innovate our research to
create new products and services directly benefits industry. We have established a
strong relationship with leading industries within the region which is contributing
to the creation of high quality sustainable employment within the region. A key
benefit of the links to industry is the training which is received by our postgraduate
students. The combination of academic rigour and industry collaboration means that
our graduates are ―industry ready‖.
This publication is intended to provide the external community with a broad
overview of the type and scope of research that is carried out in Waterford Institute
of Technology. As you will see when browsing the publication the Institute has an
active research community across all of its schools – Business, Education,
Engineering, Health Science, Humanities and Science. The publication is not
intended to cover all research areas or to provide an in-depth description of the
research topics presented but rather a flavour of the topics researched by the
Institute, which were presented at WIT Research Day 2011. We hope that it will be
helpful to members of the public, industry and potential graduate students to locate
topics of interest. Furthermore, detailed information may be obtained from the
researchers themselves or from the Research Support Unit.

I certainly hope that it will be a start of a dialogue between us, the Institute
research community and you, our stakeholders.
We would like to express our sincere appreciation to the authors who contributed
abstracts and to all those who participated in the Research Day. We also wish to
express our heartfelt thanks to the Organising Committee Members for their
substantial contributions to the Research Day. We are very grateful to all the people
who have worked hard in preparing the Research Day and making the event
successful.
We would like to express our gratitude to our keynote speaker Professor Frances
Ruane, Director of the Economic and Social Research Institute (ESRI) who delivered
a timely and undoubtedly very interesting debate on examining Ireland‘s research
and innovation funding models and policies of the past two decades. Finally, we
would also like to thank Dr. Mícheál Ó Foghlú, Executive Director Research,
Telecommunications Software & Systems Group for his insights into Research
Funding Policy.

The role of Information Systems in Supply Chain Management Department of Computing, Mathematics and Physics
Email: [email protected]
Abstract:
The traditional concern of supply chain management has been the movement of
materials from original source to the point of final consumption. In addition to the
downstream flow of materials, modern supply chain management is also concerned
with other flows such as the upstream flow of reverse logistics and the flow of funds
through the supply chain. Supply chain management seeks to carry out supply chain
activities in an efficient and effective manner. In order to do so, organisations must
recognise the need to streamline not only their internal processes but also the
processes that link to their trading partners.
Collaboration among supply chain partners enables the supply chain to better meet
the needs of the final customer. Collaborative practices act to make the supply chain
more competitive by reducing costs and adding extra value thereby increasing the
profitability of the supply chain participants. Collaboration is seen in practice in a
number of approaches to supply chain management. Vendor managed inventory
(VMI), collaborative planning forecasting and replenishment (CPFR) just-in-time
(JIT) and efficient customer response (ECR) are some of approaches to collaboration
that have brought benefits to supply chains in a number of industries. There has
also been an increasing awareness of the need to adopt an appropriate approach to
supply chain strategy. Companies have adopted lean or agile approaches, or an
appropriate combination of both, to support their supply chain strategy. In many
cases companies have moved from the traditional push based model, where goods
are produced in the hope the hope that demand will arise, to the pull based model
where goods are produced in response to demand.
Regardless of the supply chain strategy adopted or the supply chain practices
employed, the efficient and effective operation of supply chains requires the sharing
of information. Pull based models require the sharing of demand information among
supply chain participants. Push based models require the sharing of forecasts.
Collaborative approaches require information such as demand and stock levels to be
shared. The requirement for sharing of information requires the flow of information
between the supply chain partners.

WIT Research Day 2011 Book of Abstracts
This flow of information is therefore another supply chain flow in addition to the
flow of materials and the flow of funds. An information flow facility can be
constructed through the use of information and communication technology (ICT).
Traditionally, technologies such as electronic data interchange (EDI) were used for
sharing information among trading partners. These technologies were often
expensive and confined to larger trading partners. The expansion of e-commerce
technologies, based on the Internet platform, has transformed inter-organisational
exchange of information. The lower costs associated with these technologies have
opened the power of ICT to a much greater range of users. The increased
functionality of modern technologies allows increasingly powerful applications. The
ubiquitous nature of the Internet enables information to be shared among trading
partners regardless of location. Together these features allow organizations of all
sizes to participate in trade with supply chain partners on a global basis in an
efficient and cost effective manner.
The nature of information systems available to support supply chains are examined
and the usage of supply chain systems by Irish companies is reported.

Graduate Enterprise Programmes: Perspectives of Graduate
Entrepreneurs Department of Adult and Continuing Education
Email: [email protected]
Abstract
Stimulating entrepreneurship is a key economic and societal challenge to which
Higher Education Institutes (HEIs) have much to contribute. In addition to their
traditional roles of teaching and research, HEIs play a strategic role in adding value
to their regional economy by supporting and developing campus enterprise. This
third mission of HEIs is manifested in such initiatives as entrepreneurship
education; the supply of entrepreneurial talent to create new businesses to generate
employment and wealth; campus incubation; and the commercialisation of R&D. Of
these, entrepreneurship education has become a panacea for generating employment
and prosperity, however, there is little empirical evidence to support the assumption
that entrepreneurship education can generate better outcomes of entrepreneurial
activity. There is a lacuna of research exploring entrepreneurs‘ perspectives of
graduate enterprise programmes, which this research seeks to address. By
examining entrepreneurs‘ perspectives of the benefits and limitations of a graduate
enterprise programme, this research examines if participants have actually achieved
sustainable entrepreneurial outcomes vis a vis graduate entrepreneurs who did not
participate in such a programme.
Using the South East Enterprise Platform Programme as a case-study, this research
provides a comprehensive analysis of the needs of graduate entrepreneurs at the
crucial start-up phase of their business and identifies what supports HEIs can
provide to them through graduate entrepreneurship programmes. This research is
timely given the government‘s priority of supporting the development of high-
growth, export-oriented indigenous enterprise to rejuvenate the Irish economy. It
contributes to the field of entrepreneurship education by providing (i) a synthesis of
entrepreneurs‘ perspectives of a graduate enterprise programme and (ii)
recommendations to HEIs, education and enterprise policy makers for
enhancements to graduate enterprise supports/programmes. In addition, this
research identifies areas worthy of further research to advance significantly the field
of graduate entrepreneurship education.
Keywords: Graduate Entrepreneurship Education.

Finding the Red Thread” The Role of the Learning Space in Transformative
Learning in Executive Education Department of Adult and Continuing Education
Email: [email protected]
Abstract:
Achieving an Executive MBA presents candidates with certain challenges –
undertaking the study, completion of assignments and course requirements,
maintaining a work-life balance in addition to experiencing personal change and
development in many instances. Business schools should be clear about what
‗business they are in‘ and work to identify what the adult learners educational
objectives and expectations are from their proposed programme of study. A
narrowing of the gap between the two sets of expectations would reduce the noise
and confusion in the teaching-learning environment of unmet expectations on both
sides.
This case study is about the development of a framework for transformative learning
in executive education in a Scandinavian context. Transformative learning as a
theme emerged from the practical experience of the author as a facilitator and
academic responsible for an organisation development (OD) project in a business
school in Scandinavia. This OD project focused on consolidating and enhancing an
existing leader development programme (LDP) within an executive masters in
business administration (EMBA) teaching-learning environment (TLE). It was
during the research project, in conversations, interviews, discussion groups,
workshops and archival data that students explicitly referred to the learning space
of the LDP as being instrumental in its impact on their overall learning experience.
Hence, transformative learning as a phenomenon emerging out of practice and its
relation to the learning space of the LDP became the subject of this investigation.
Contributions to knowledge from this research study relate generally to adult
education and to the tradition of critical reflection. A particular contribution is to the
area of transformative learning and the development of a framework for creating a
distinctive learning space in executive education. A related contribution is in the
identification of the key role of the learning team coupled with a range of
components that must be employed within the learning space. Here, trusted
relationships among members of the learning team are essential to the development
of dialogue, critical reflection and profound discourse. Facilitation of the learning
team toward enhancing its performance is necessary to support a learning space
where the opportunity for transformative learning can occur.

Clifford Odets and the Theatre of the Great Depression Department of Languages, Tourism and Hospitality
Email: [email protected]
Abstract:
The first performance of Clifford Odets‘s play Waiting for Lefty in March 1935 was
declared ―the birth cry of the thirties‖. At the height of the American Depression,
Odets—and the Group Theatre with which he was identified—came to be seen as a
means by which American youth ―had found its voice‖. This paper will examine the
play, Waiting for Lefty, in the context of the Depression, and will consider the
relationship between works of art and social crisis. In so doing the paper will seek to
identify some questions applicable to the current Irish economic and social situation.
Odets, from being celebrated as the great hope for the American theatre, came to be
derided as the ultimate sell-out. While Odets had some success in the theatre after
Waiting for Lefty, he found fame and fortune in Hollywood where he went in 1936 to
write movies (while there, he wrote movies like The General Died at Dawn and None
but the Lonely Heart, as well as contributing to The Sweet Smell of Success and
many others). The paper will also consider the life and work of Odets after Waiting
for Lefty, in particular this seeming seduction by Hollywood: the one-time golden boy
of the theatre of protest ended up writing vehicles for Elvis Presley and television
screenplays. Odets‘s career dramatises the tensions that exist in culture between
seemingly High Art and popular entertainment, as well as providing an illustration
of the seeming compromises involved for anyone who comes into contact with the
Hollywood ―Dream Factory‖. The paper will consider the relationship between art
and morality and in so doing raise larger questions about the moral responses
demanded to wealth, privilege and, most of all, talent.
Keywords: Literature, Film, Drama, Culture.

Competitive Activities in New Technology Industries Department of Engineering Technology
Email: [email protected]
Abstract:
The impact of new technologies on incumbent industries has been a focus of research
for decades. Schumpeter (1942/1976) coined the phrase ‗creative destruction‘ to
describe it, while more recently Christensen (1997) used the term ‗disruptive
technology‘ in a similar sense. But other contributors (e.g. Itami and Numagami,
1992; Myers, Sumpter, Walsh and Kirchhoff, 2002; Hopkins et al., 2007) have
addressed a more fundamental issue, which is that new technology competition is
different to ‗normal‘ competition, with Porter, early on, explicitly stating that it
‗change[s] the competitive rules of the game‘ (Porter, 1983, p3). This presentation
considers the nature of competition in new technology industries, focusing on the
competitive dynamics evident as stent technology was introduced, rather than solely
on the technology‘s impact on an incumbent.
Despite broad acceptance that new technology competition is unique, and that it
possesses a large potential to engender change, few contributions specifically
address the nature of new technology competition, and how the change it is
associated with comes to be. These questions are of particular interest due to the
need to grow Ireland‘s indigenous export base and to benefit from sustained
investment in science, technology and innovation at national level (National
Competitiveness Council, 2010). Understanding the nature of competition in new
technology industries provides innovators with an insight into the types of
challenges they may face as they attempt to introduce their new technologies.
Findings indicate that distinctive parallel strategies were present in the stent
industry as the technology was being introduced: one between direct competitors;
another between the industry and the incumbents. Legal activities within new
technology competition are revealed to be substantially more influential than has
been previously recognised. Their nature, extent and scale as stents were
introduced, was very dramatic. Alliances, acquisitions and the management of
relationships between new technology firms and other actors were central to the
competitive environment, and an extreme ruthlessness is evident within these
relationships.
Keywords: Competitive strategy; new technology; innovation; technological change.

Exercise Self-Efficacy in Trainee Gardaí
following an E-Counselling Intervention Department of Health Sport and Exercise Science
Email: [email protected]
Abstract:
Background
An Garda Síochána has focused recent attention on the rising inactivity levels and
difficulties in maintaining a healthy lifestyle that is prevalent in today‘s society and
is mirrored in its employees. Successfully adopting an exercise regimen requires
confidence in one's ability to engage in exercise, also referred to as exercise self-
efficacy. Exercise e-counselling was identified as the most effective and innovative
intervention to reach trainee Gardaí and develop their exercise self-efficacy while in
the Garda College, Templemore, and in their Garda stations nationwide. The
primary research questions examined the effects of e-counselling on exercise self-
efficacy (McAuley, 1993), stress (Reeder et al, 1973) and self-esteem (Rosenberg,
1989). The secondary research questions focused on supporting areas of interest,
including additional outcome measures (blood pressure, body composition and
estimated VO2max) and other categorical variables.
Methods
The intervention group consisted of 274 participants. The control group consisted of
234 participants. Therefore there were 508 participants in total in this study, 343
(67.5%) males and 165 (32.5%) females. All participants were trainee Gardaí. The
intervention lasted 11 months and consisted of generic exercise self-efficacy
structured e-mails to the intervention group once a week and an interactive website
was developed. Participants were encouraged to reply to generic e-mails for one-to-
one e-counselling. Participants were tested at pre- and post-intervention for changes
in exercise self-efficacy, stress and self-esteem, as well as a battery of physiological
measures. An evaluation questionnaire was also completed following intervention.

Results
There was no significant effect found for exercise self-efficacy as a result of the
intervention. Female self-efficacy to overcome barriers decreased even more than
males over time (total mean score decreased from 54.76 to 42.91 for females and
from 54.4 to 51.4 for males).
Stress scores were maintained within the intervention group (p = 0.478) and
increased significantly in the control group (p = 0.017). There were a number of
significant physiological changes. 88% of the participants who engaged with the e-
counselling were males.
Conclusions
In relation to specifically increasing the trainee Gardaí self-efficacy to exercise, it
was shown that e-counselling and generic exercise self-efficacy structured e-mails do
not seem to be enough to maintain or increase exercise self-efficacy or physiological
outcomes. E-mails and Internet perceptions were, however, positive, which may
have implications for future study design. Male trainee Gardaí were shown to
engage more frequently with e-counselling.

The educational merits of incorporating a service-learning component in
the Nursing Curriculum Department of Health Sport and Exercise Science
Email: [email protected]
Abstract:
Context and Background
Service-learning is a teaching and learning strategy that integrates meaningful
community service in the curriculum to enrich the learning experience, teach civic
responsibility, while providing a tangible benefit for the community. The ‗Save a
Life‘ programme was designed to engage nursing students with a community
service-learning experience by teaching emergency Basic Life Support (BLS) in
schools. Eight undergraduate nursing students underwent a service-learning
placement delivering the ‗Save a Life‘ programme in 3 Post-Primary schools as part
of their community practice placement.
Aim of the Study
The goal of this study was to evaluate the effectiveness of the ‗Save a Life‘
programme to teach emergency Basic Life Support in Post-Primary schools and
establish the educational merits of incorporating a service-learning component in
the nursing curriculum.
Research Methodology
The study used a sequential mixed methods design, encompassing two phases.
Phase one used a pre- and post-test to evaluate the impact of the ‗Save a Life‘
programme on transition year students‘ (n = 100) and teachers‘ (n = 59) BLS
knowledge, skills and attitudes. Phase two of the study used focus groups to
illuminate nursing students‘ (n = 8) experiences of undertaking the service-learning
placement.
Key findings and Conclusions
The pre- and post-test training scores indicate that the ‗Save a Life programme‘
impacted positively on students‘ and teachers‘ BLS knowledge, skills and attitudes
(p < .05). Nursing students reported positive learning outcomes from the service-
learning experience.
22
WIT Research Day 2011 Book of Abstracts
The key categories that emerged from focus groups were enhanced skills acquisition,
conceptualisation of health, importance of the ‗chain of survival‘ in saving lives and
empowerment. Service-learning is an effective pedagogical approach that can be
incorporated into undergraduate nursing programmes. The service-learning
placement enhanced nursing students‘ cognitive, psychomotor and affective
development, which are fundamental to professional nursing practice. The findings
inform the potential contribution of service-learning in developing nursing students‘
competence, confidence and preparedness for nursing practice.
Relevance and Implications
This study has particular relevance and implications for nurse educators who seek to
develop curricula that will prepare nurses with the knowledge, skills and attributes
necessary to meet projected health care needs. It will be of interest to lecturers who
support innovative pedagogy and are engaging with communities to improve higher
education. The findings have implications for people who strive to improve
bystander resuscitation in Ireland, and advocate cardiopulmonary resuscitation
training in communities to improve the chance of survival for victims of cardiac
arrest.
Keywords: Service-learning, Experiential learning, Innovative pedagogy, Bystander

Plastic Antibodies for isolation and purification of pharmaceutical
compounds Department of Chemical and Life Sciences
Email: [email protected]
Abstract:
Molecularly imprinted polymers (MIPs) are synthetic polymeric materials, prepared
by polymerisation of an appropriate functional monomer in the presence of a
template (e.g. pharmaceutical, food component or environmental pollutant) and
excess of a cross-linking monomer, resulting in cavities within the matrix of the
polymer that are capable of selective and reversible binding of the targeted analyte,
hence the term ―plastic antibody‖ has been used to describe them. MIPs have been
utilised in a variety of analytical applications, including chiral stationary phases for
chromatography, solid phase extractions and sensing. Successful imprinting is based
on the strength of template – functional monomer interactions in the pre-
polymerisation phase, as an increased population of solution complexes will lead to a
larger number of high fidelity binding sites. In order to shift the equilibrium towards
template – functional monomer complexation, an excess of the functional monomer
is commonly used, leading to random distribution of functionality throughout the
polymer matrix, thus promoting non-specific binding to the imprinted phase. Here
we report the synthesis of polymers imprinted with S-ibuprofen, a non-steroidal
anti-inflammatory drug, prepared by stoichiometric non-covalent imprinting, using
4-methyl-2-acrylamidopyridine as the functional monomer. The resulting polymers
were characterised using Solid State NMR, N2 sorption porosimetry, SEM and
particle size analysis. Polymer particles were packed into HPLC columns whereby
rapid, near-baseline enantio-separation of rac-ibuprofen was achieved, while the
polymers were able to discriminate between the template and other structurally
related compounds. The number of binding sites and binding constants were
calculated using frontal chromatography. Furthermore, a colour difference between
imprinted and blank polymers, attributed to the binding event and observable by
naked-eye and UV light inspection, suggests potential application of the materials as
sensing elements. Such materials can be used for rapid, inexpensive purification of
pharmaceuticals, ensuring their suitability for use in drug formulations and
minimise the risk posed to public health by undesired enantiomers.

EXCITEing Irish Communities: A 4 lens model to support the use of
Information and Communications Technology for Irish Voluntary
Organisations Department of Computing Mathematics and Physics
Email: [email protected]
Abstract:
The value of Information and Communications Technology (ICT) as a management
facilitator, which can help deliver improvements in efficiency, effectiveness and
competitive advantage is well established. It is also clear that in these respects ICT
is of value to both the private and the public sector. However, there are other parts
of society that have yet to derive the potential benefits of ICT. These include both
formal and informal groups of people who have a common connection, interest,
friendship or bond, who wish to satisfy their needs and enhance their ability to
interact. These are commonly known as voluntary organisations.
Community based voluntary organisations have emerged as a special area of
interest to academics and Information System (IS) practitioners and their
importance has also been recognised by Governments at National levels in many
countries. These Local Voluntary Organisations (LVOs) can be based on community,
political, sporting, recreational, religious or civil needs. LVOs are an integral part of
modern Irish life; they contribute to delivering a higher quality of life and when
looked at through various lenses, they may be seen as also facilitating information
dispersion, knowledge acquisition, employment creation and service provision, and
play an important role in integrating individuals and communities.
In recent times, the term Community Informatics (CI) has emerged as an IS field of
study. Community Informatics can be viewed as an interdisciplinary approach to
community development that utilises ICTs to enable community processes and helps
communities realise their full ICT potential (Loader and Keeble, 2001). According to
Gurstein (2007) CI represents an evolutionary advance on traditional systems
development by combining ICTs with the dynamism and adaptability of life as lived
in civil communities. Community Informatics as a field of study and in practice has
been described by Gurstein (2008) as systematically approaching IS with a
‗community‘ focus.

WIT Research Day 2011 Book of Abstracts
This research investigates the development a Community Informatics (CI) model to
support the use of ICT by Irish communities and their LVOs.The proposed CI model
should recognise the uniqueness and diversity of each LVO and its members, in
terms of knowledge, experiences and needs and provide a mechanism to improve
them through appropriate ICTs.
This diversity dictates that a special focus with specific lenses is required for a CI
model; which will enable greater participation by people in identifying
organisational ICT requirements, by utilizing participatory design approaches. A CI
model will establish planning, support and management processes that will make
Irish LVOs directly responsible for their own ICT future. This is one of the pervasive
concerns for Irish LVOs, who wish to use ICT to improve their operation and
empower their members.

‘The Paper Witness’: The Analysis of Irish Music Manuscripts as
Information Sources Department of Applied Arts
Email: [email protected]
Abstract: The notion of collecting Irish music is not a new one, but historically the main waves
of collection appear to have coincided with periods when Irish music was at a low
ebb. Edward Bunting (1773-1843) collected the remnants of a Gaelic harp tradition
in 1792 and there was a proliferation of collectors such as George Petrie (1790-1866)
associated with the Society for the Preservation and Publication of Irish Music,
active in the period 1840-1850, immediately after the ravages of the famine had
disseminated Irish music. These eighteenth and nineteenth century collectors were
invariably trained in the European art music tradition and were selective in the
material that they collected, at the very least restricting their collections to what
they saw as truly Irish items. Patrick Weston Joyce (1827-1910) and Richard
Henebry (1863-1916), both traditional musicians, were active as collectors of Irish
Music at the end of the nineteenth and early twentieth century, still collecting post-
famine material. An increased facility in music notation amongst traditional
musicians and a decline in Irish music led to a wave of private music collections by
traditional musicians in the 1930s, the same decade that also saw the formation of
the Irish Folklore Commission.
A number of the music manuscripts used by these collectors are still extant in
libraries and archives, both in Ireland and abroad. In many cases these manuscript
collections are incomplete, disorganised and often scattered in different repositories.
In addition, many of the collections are large and most collectors shared their
sources, contributed material to one another‘s collections, and even lent, or gifted,
their entire collections to their fellow collectors. In recent times research in Irish
music at WIT has concentrated on analysing the main pre-1910 manuscript
collections of Irish music. These include the collections of Edward Bunting (1773-
1843); Philip Carolan (1839-1910); Henry Hudson (1798-1889); George Noble
Plunkett (1851–1948); John Edward Pigot (1822-1871); Patrick Weston Joyce (1827-
1910) and Richard Henebry (1863-1916). The proposed paper will discuss the
methodology used in the study: primarily historical research, musical analysis,
palaeography and the consideration of textual and non-textual information.
27
WIT Research Day 2011 Book of Abstracts
While the research into each of these manuscripts is valuable and unique in its own
right, it is the resultant critical mass and opportunity to see how the individual
collections inter-relate and the comprehensive view of Irish music which emerges
that is particularly valuable in the WIT study.
The extant manuscript collections contain a selection of tunes and settings which
have now vanished from the popular repertory both locally and nationally. The vast
majority of the tunes, and indeed many of the tune-types, which the manuscripts
contain are no longer found in the aural repertory.
The current research therefore helps to establish the provenance of manuscripts,
give an understanding of their construction, contents and inter-relativity, and
thereby provides a snapshot of the music in rural Ireland at a particular point in
time.
Keywords: Musicology, culture, palaeography, Irish studies and history.

Optical Fibre Manipulations Enabling State-of-the-Art Technologies Department of Computing, Mathematics and Physics
Email: [email protected]
Abstract:
Since the pioneering work of Charles K. Kao and co-workers in the 1960s to reduce
transmission losses in silica optical fibres, the optical fibre has become ubiquitous.
As a low-loss photonic conduit, optical fibres have revolutionised
telecommunications, providing the means to transmit large amounts of data, voice
and video information. In the world of sensing, fibre gratings, for example, have
been employed for structural health monitoring, environment monitoring and
exploration including temperature sensing [1]. Side-polished and tapered fibres are
used as substrate platforms in biological and chemical sensing applications. Optical
fibres have also been used to image internal organs as a means of providing medical
diagnoses and for minimally invasive and laser surgeries where treatments have
been delivered more effectively to reduce levels of trauma and expedite healing
times. Optical fibres have been continually developed and manipulated over the
decades in terms of physical design, chemical composition and post-processing
techniques. Developments have resulted in enhanced performance in established
areas of deployment and have provided new functionalities that have been exploited
across ever-increasing application spaces. One key example includes the erbium
doped fibre for all-optical amplification, indeed there is continuing work to realise
practical all-optical regeneration of long-haul signals [2]. Another key example is the
invention of photonic crystal and microstructured optical fibres [3] that have
provided mechanisms for: octave-spanning frequency comb generation; photonic
bandgap guidance; and photonic gas microcells [4].
As technological challenges continue to emerge and as barriers arise with existing
technologies, new optical fibre designs combined with optical fibre processing
techniques are enabling next generation functionalities for state-of-the-art
technologies. Biological and chemical sensing applications, for example, are taking
advantage of microstructured fibres that facilitate the intimate interaction between
core guided light and biological and chemical fluids that fill the surrounding holes
for monitoring and detection [5]. In Astrophotonics, multi-core fibres (MCFs) are
postprocessed and combined with existing fibres to form optical circuits that enable
the observation of distant galaxies using ground-based instrumentation [6, 7].
29
WIT Research Day 2011 Book of Abstracts
Multi-core fibres are also being engineered to enable higher communication
bandwidths, through spatial division multiplexing, as a potential solution to the
imminent capacity crunch in telecommunications networks. Finally, as high-speed,
high-density optical buses, multi-core fibres provide an attractive platform to enable
Exascale Computing, the next generation of high-performance super-computers,
operating within the constraints of tightly confined spaces and low power budgets.

Finite Element Analysis: A powerful tool for Industrial Research and
Development Department of Engineering Technology
Email: [email protected]
Abstract:
Finite Element Analysis or FEA is a powerful research and development as well as
failure analysis tool. FEA consists of a computer model of a component or design
that is stressed and analyzed for specific results. It is used in new product design,
and existing product refinement. FEA allows detailed visualization of where
structures bend or twist, and indicates the distribution of stresses and
displacements. FEA allows entire designs to be constructed, refined, and optimized
before the design is manufactured. It provides a means to minimise the costly
prototyping phase of a project by allowing the limitations of a prospective design be
explored within a virtual environment. Potential issues can then be addressed with
design modifications resulting in a greatly optimised design. A new design concept
may be modelled to determine its real world behaviour under various load
environments, and may therefore be refined prior to the creation of drawings. It is
also useful in minimizing weight, materials, and costs. Once a detailed CAD model
has been developed, FEA can analyze the design in detail, saving time and money by
reducing the number of prototypes required. A variety of specializations under the
umbrella of the mechanical engineering discipline (such as aeronautical,
biomechanical, and automotive industries) commonly use integrated FEA in design
and development of their products. SEAM is able to verify a proposed design will be
able to perform to the client's specifications prior to manufacturing or construction.
Modifying an existing product or structure FEA is utilized to qualify the product or
structure for a new service condition. This potent design tool has significantly
improved both the standard of engineering designs and the methodology of the
design process in many industrial applications.
SEAM has commercial ANSYS FEA mechanical package and is applying it to a
number of customer projects as well as in house development activities. Some
notable customer tasks are the analysis of cable fixtures for the electricity supply
network, the development of a superior drill-head for mining industry and the
optimised manufacture of contact lens. SEAM is also perusing projects related to the
acoustic and thermal modelling of structures fabricated from materials from
renewable sources. In the biomedical sector SEAM is using FEA to analysis novel
implants and materials for the interpositional arthroplasty of the knee joint.
31
WIT Research Day 2011 Book of Abstracts
The introduction of FEA has substantially decreased the time to take products from
concept to the production line. It is primarily through improved initial prototype
designs using FEA that testing and development have been accelerated. In
summary, benefits of FEA include increased accuracy, enhanced design and better
insight into critical design parameters, virtual prototyping, fewer hardware
prototypes, a faster and less expensive design cycle, increased productivity, and
increased revenue. In this presentation some of these topics will be explored.
Keywords: Finite Element Analysis, virtual prototyping, design optimisation,

The Role of Affective Equality in Community Education Department of Adult & Continuing Education
Email: [email protected]
Abstract: Community education is a field of adult education that overlaps with the field of
community development. It aims to engage the most excluded of groups in a process
that builds self-confidence and community activism. It is inspired by Paulo Freire‘s
(1970) analysis that education is always political: it either results in learners fitting
into the social and political system (domestication), or becoming able to change it
(liberation).
Other research exists about the processes essential to liberatory education that are
common to popular education globally (Walters and Manicom 1996, Connolly 2008),
and current research in Ireland (Bailey 2011) is concerned with identifying the
outcomes of community education for participants. This research is concerned
mainly with identifying habitus changes (Bourdieu 2001) in participants, the
dispositional shifts that are preconditions for active participation in wider society, or
what Lynch describes as solidarity work (Lynch et al 2009). Bourdieu takes a very
pessimistic view of the forces of domination and subordination in culture, especially
those based on gender, and claims that habitus cannot be shifted by cognitive
approaches.
The research asks the question: to what extent a learning culture enables a learner
gain and practice a greater sense of agency. Does a women-only culture have any
effect on participants? Using the methodology of institutional ethnography,
fieldwork was carried out for a period of six weeks in a community education
organization. A major finding is the extent to which participants speak in terms of
feelings. This contrasts with formal education‘s privileging of cognitive
developmental processes. Belenky, Clinchy, Goldberger and Tarule‘s (1997) Women‘s
Ways of Knowing identify five major perspectives on knowing: Silence, Received
Knowledge, Subjective Knowledge, Procedural Knowledge, and Constructed
Knowledge (Belenky et al 1997 p.15). (The final stage is similar to that identified by
William Perry‘s (1970) study of undergraduate learners).
33
WIT Research Day 2011 Book of Abstracts
The women involved in the organisation‘s programmes show movement, or a shift in
habitus, from the Silent stage to that of Subjective Knowing. Participants‘ talk of
feelings does not mean that this is therapeutic education, as warned against by
Ecclestone and Hayes (2009): it is however an indicator that participation is having
a therapeutic effect, especially on their perceptions of themselves as learners. Their
relationship to knowledge and knowing is changing.
The concept of Nurturing Capital (Lynch et al 2009) explains the relationship
between receiving sufficient nurturing care and the ability to develop the self,
connect with others, and work in solidarity with others. Affective equality means
that the role of feelings and care should be seen as a vital element in adult education
and development work generally.

education.

Making sense of learning from experience: Facilitating reflective practice
in an undergraduate work placement programme Department of Management and Organisation
Email: [email protected]
Abstract:
There is growing interest in how students ‗learn‘ from actual experience and how
this learning can be combined with curriculum learning to help develop reflective
skills in graduates (Cunliffe, 2004; Francis and Cowen, 2008; Olsson et al., 2008).
While work placement programmes are now commonplace in business degree
programmes (Ayman et al., 2003; Elmuti, 2004; Hess, 2007; Starkey and Tempest,
2005), educators have struggled with how reflective skill enhancement can be
achieved among undergraduates partaking in such programmes, and how practice-
theory links can be strengthened when a student is in an experiential learning
mode. This paper explores the concept of the learning moment in an undergraduate
placement programme. For the purposes of this paper, the learning moment is
defined as that moment where students ―make sense of learning from experience‖
(Freisner and Hart, 2005: 118).
The paper begins by examining the literature relating to individual skills required in
the reflective process, including log production, which can help students to identify
and conceptualise the learning moment in context. It goes on to discuss
undergraduate challenges when identifying and expressing learning moments in an
experiential learning cycle. The authors adopt an action research methodology, and
observe student placements in their capacity as programme leader and academic
faculty members. The programme discussed in this paper forms part of a ‗flexible
term‘ carried out in the third year of a four year honours business degree
programme.
The observed students are placed in either a teaching role or a community-based
work environment as part of the ‗flexible term‘, and are supported by an educational
programme completed in parallel with the student placement.
Each student maintains a reflective log for the duration of the programme which
have been assessed by the authors based on pre-established criteria relating to the
experiential learning process (Kolb, 1976, 1984), providing insight into the learning
moment in context.

The Nanotechnology Research Group at WIT provides interdisciplinary research
opportunities for Engineering and Science graduates. Focusing on key areas of
activity the group blends expertise in Chemical and Life Sciences with expertise in
Engineering and Physics to develop novel solar harvesting and sensor technologies.
Scanning Probe Microscopy (SPM) plays a key part in the daily activities of the
research group. While the group possesses some commercial SPM instruments
much effort goes into the in-house design and fabrication of customised instruments
for nanoscale characterisation. This presentation will outline to a general audience
an overview of our activities with a particular emphasis on environmental
nanotechnology. The talk will highlight some of our research into low cost
mechanical sensors for environmental monitoring and demonstrate the potential
sensitivity of these sensors. More sophisticated label free biosensor technologies will
be discussed, these technologies range from sophisticated molecular counting
methods to the detection of the extraordinary optical transmission of light through
nanosized apertures. Finally the talk will conclude with a discussion of photovoltaic
energy harvesting technologies with an emphasis on printable solar technologies and
the potential for solar energy in Ireland.

Nano-Positioning Research in WIT Department of Engineering Technology
Email: [email protected]
Abstract:
Nano-positioning is a significant challenge that is the subject of research at both
national and international levels. While the positioning of an instrument at
nanometre accuracy is feasible, and there are several commercial nanopositioning
‗stages‘ available, the tracing of a 3-D contour, with nanometre precision, presents a
considerable engineering challenge. This presentation describes a series of related
projects designed to lead to the construction of a laboratory instrument to achieve
this.
Nano-positioning has been a focus of substantial work within the AMT group in WIT
in recent years. Two recent projects focused on in-process automation of
measurement. One designed a quality measurement system, while the other
established a measurement and control system for the manufacture of ball-bearings.
These projects were undertaken with industrial partners and established a
knowledge base and range of skills in the area of in-process measurement and
control. This work was followed by a project in the implementation and operational
valuation of a high-precision measurement-centred control system for a high volume
manufacturer, which was completed in 2010. Parallel to these projects a PhD
student has progressed work in the area of positioning with nanometre resolution in
a noisy environment.
At this point the factors influencing the functionality of a nano-positioning
instrument have been investigated, the instrument has been designed and the key
core components have been fabricated. The next stage of this work focuses on the
construction and calibration of a nano-positioning instrument, which can trace a
contour in three dimensions.
Several challenges are anticipated, including the ‗straightforward‘ challenges of
precision placement and alignment of the component parts of the instrument. It is
also expected that constructing the instrument will reveal difficulties associated
with mechanical construction of nano-precision instruments. Error management,
limiting the impact of environmental factors and control are also issues which will
need to be managed.

Management of Monitoring Services in the Cloud
Telecommunications Software & Systems Group
Email:[email protected]
Abstract:
Cloud computing has become a prominent and at the same time promising business
area leading to the further specialization and proliferation of the ICT market. The
major activity in cloud computing is focused in the design of software solutions
supporting multiple services with the minimum investment in infrastructure. At the
outset, it offers reduced cost of operation for the clients when a shared infrastructure
can make statistical gains in regard of resource utilization. Furthermore cloud
computing offers capabilities for better adaptation to changing business and IT
operations following strategic objectives, and it could even have the prospect of
providing improved features when it comes to resilience and robustness of the
performance of applications.
An emerging alternative to solve cloud computing decision control, from a
management perspective is the use of formal languages as a tool for information
exchange between the diverse data and information systems participating in cloud
service provisioning. These formal languages rely on an inference plane [1][2]. By
using semantic decision support, and enriched monitoring information management
decision support is enabled and facilitated. As a result of using semantics a more
complete control of service management operations can be offered, hence a more
integrated management, which responds to business objectives. This semantically-
enabled decision support gives better control in the management of resources,
devices, networks, systems and services, thereby promoting the management of the
cloud with formal information models [3].
We are addressing the needs to manage the cloud when policies are being used as
the mechanism to represent and contain Description Logic (DL) to operate
operational rules. For example, the SWRL language [4][5] can be used to formalize a
policy language to build up a collection of model representations with the necessary
semantic richness and formalisms to represent and integrate the heterogeneous
information present in cloud management operations. This approach relies on the
fact that high level infrastructure representations do not use resources when they
are not being required to support or deploy services [6][7]. Thus with high-level
instructions the cloud infrastructure can be managed in a more dynamic and optimal
way.

We can identify several cloud usage patterns [8] based on bandwidth, storage, and
server instances over time. Constant usage over time is typical for internal
applications with small variations in usage. Cyclic internal loads are typical for
batch and data processing of internal data.
Highly predictable cyclic external loads are characteristic of web servers such as
news, sports, whereas spiked external loads are seen on web pages with suddenly
popular content (c.f. ―slashdotted‖). Spiked internal load are characteristic of
internal one-time data processing and analysis, while steady growth over time is
seen on startup web pages.
The cloud paradigm enables applications to scale-up and scale-down on demand, and
to more easily adapt to the usage patterns as outlined above. Depending on a
number or type of requests, the application can change its configuration to satisfy
given service criteria and at the same time optimise resource utilisation and reduce
the costs. Similarly clients - which can run on a cloud as well - can reconfigure
themselves based on application availability and service levels required.
We address on-demand scalability and scalability prediction of a service by
computing a performance model of the architecture as a composition of performance
models of individual components. Exact component‘s performance modelling is very
difficult to achieve since it depends on a various variables such as available memory,
CPU, system bus speed, and caches. Instead of exact performance model we use an
estimated model calculated from monitoring data.
In this talk we address a number of research challenges for cloud computing. It is
not intended to be an exhaustive list of research challenges in this emerging area,
but rather to introduce important issues with respect to improving cloud
management, and which we aim to investigate as part of the SFI FAME project.
Figure 1 depicts these trends based on well identified cloud demands [9].

Inward foreign direct investments as catalysts for growth in developing
countries: an empirical study Department of Management and Organisation
Email: [email protected]
Abstract: Over the last three decades there has been an exponential growth and an
increasingly competitive market for global foreign direct investments (FDI). Global
FDI net inflows have continued to rise consistently since the late 1970s. Current
projections estimate that FDI inflows will increase to $1.5 trillion in 2011 and $2
trillion in 2012 (UNCTAD WIR Report 2010).
Although most of the global FDI goes to the developed economies, mainly the triad of
Japan, the European Union and the United States of America, FDI levels to
developing countries especially Sub Saharan Africa (SSA) have increased since the
early 1980s. Between 2000 and 2008, FDI to SSA have increased nine fold ―from $9.7
billion to $87 billion: (UNCTAD WIR Report various editions)‖. Many developing
countries have incorporated inward FDI as a vital component in their strategy for
economic growth. Indeed, most SSA African countries have in recent times made
attempts to improve their business climate to attract FDI, but there are still factors
that continue to inhibit inward FDI such as political instability, poor macro-
economic environments and a low level of human capital development.
There have been several studies done on the effects of FDI on the host country, most
of the empirical research does not differentiate between developed and developing
countries (Borensztein et al 1998; Olofsdotter, 1998; de-Mello, 1999; Carkovic and
Levine, 2002; Chloe, 2003; Bengoa and Sanchez-Robles, 2003) leading to incorrect
inferences being drawn( B. Blonigen and M.Wang, 2004).
This study will examine if there is causality between FDI carried out in developing
countries and economic growth. An empirical study of 12 SSA developing countries-
specifically in SSA countries using comparable measures of institutional, economic
and political milieu will be undertaken. The effects of FDI on SSA is under
researched , this study will contribute to our understanding and explanation of the
impact of FDI on economic growth in developing countries in the context of SSA
countries.

As is standard in FDI-growth literature, the dependent variable will be the average
annual GDP growth rate. Data will be sourced from UNCTAD World Investment
Reports (various editions), World Bank data, World development indicators, IMF
and the individual country‘s‘ national statistics body. The number of countries
selected for this study, and the variables that were chosen for the regression were
determined by data availability and based on the fact that most of FDI inflows into
SSA are largely concentrated in these countries.
This study will be of interest to policy makers especially in developing countries in
their efforts to attract foreign direct investments. It will also be of interest to
multinational corporations in the formulation and implementation of market entry
strategies to developing countries.
Keywords: Foreign direct investment, developing countries, economic growth.

A framework to measure server performance when evaluating access
control policies in ICT systems Telecommunications Software & Systems Group
Email: [email protected]
Abstract:
Access control is an essential part of a secure ICT system. It protects the privacy,
confidentiality and integrity of data stored on or transferred between ICT systems.
Defining access control policies, and designing the infrastructure to support these
policies, is non-trivial. The problem is compounded by the drive toward ever more
fine-grained access control requirements, resulting in more complex policies that
need to be evaluated for each access request. Researchers have recently turned their
attention to the access control performance as this is a growing problem. This in
turn has drawn attention to deep questions over how to represent and reason over
complex rule bases; this is a rich area for study.
As rationale, we note that major suppliers of hardware and software that provides
and depends upon access control (such as Cisco) approached TSSG and requested
asked us to study the problem and share our recommendations with them.
Our chosen methodology is to build a software testbed in which to perform
experiments. That is, in our experiments most of the likely factors influencing
performance are controlled and can be varied singly or in groups as needed. Our
experiments are also repeatable so the results can be verified by others, and can be
included in larger studies because the experimental conditions are known explicitly.
The key to achieving these objectives is that we have built a generalised
environment in which specific software components, policies, request profiles, etc.,
can be inserted. The software components participating in the experiments are
insulated from the generic environment by adapter components that ensure
experimental conditions are not biased in favour of particular components.
Our experiments have compared two open source Policy Decision Points (PDPs) and
measured timings show marked differences in their behaviour. The best known has
quite variable performance – some access requests take much longer to decide than
others. The alternative has much reduced variability and generally more favourable
performance characteristics.
46
WIT Research Day 2011 Book of Abstracts
We ran simulations based on these service time measurements and discovered that
the less well-known alternative has higher effective throughput. Thus performance
prediction, in limited circumstances, is possible.
Our results to date have been encouraging and have led to two papers being
accepted for conferences. Our next steps are to gain greater control of more factors,
and thereby to implement more comprehensive and realistic domain models to make
stronger performance predictions and hence derive recommendations for better PDP
performance.
Keywords: Access control, Policy evaluation, Server performance.

Effect of feeding genetically modified Bt (MON810) maize to pigs from 12
days post-weaning for 110 days on serum and urine biochemistry Department of Chemical and Life Sciences
Email: [email protected]
Abstract:
Perceived health risks are among the main reasons for low acceptability of
genetically modified (GM) feed ingredients. The aim of this study was to evaluate
the effect of feeding GM maize to pigs from 12 d post-weaning to slaughter for 110
days on health as assessed by serum and urine biochemistry. Seventy-two entire
male pigs (10.7 ± 1.9 kg live weight) were blocked by weight and litter and randomly
assigned to one of four treatments (d 0); T1- non-GM maize (nGMm) in diet to d 110;
T2- GM maize (GMm) in diet to d 110; T3- nGMm in diet for 30 d followed by GMm
to d 110; T4- GMm in diet for 30 d followed by nGMm to d 110. Serum collected on d
0, 30, 60, 100 and 110 (n=10/trt) was analysed for liver and kidney health indicators
(alanine aminotransferase, aspartate aminotransferase (AST), γ-glutamyl
transferase, alkaline phosphatase, total protein (TP), urea (SU) and creatinine (SC).
Creatinine and protein were measured in urine collected on d 110 to further assess
kidney health. Urine data were analyzed as a one-factor ANOVA using the GLM
procedure of SAS. For all other parameters, data were analyzed as repeated
measures with the MIXED procedure of SAS with baseline (d 0) values included as a
covariate in the model. For serum biochemistry, d 0 values were used as a covariate
in the model. On d 30, SU was lower for T3 compared to T1, T2 and T4 (2.9 vs 3.9,
4.7 and 4.2 mmol/L, respectively; SEM=0.37; P=0.03). On d 110, there was a higher
concentration of SC in pigs fed T3 and T4 compared to T1 and T2 (181.5 and 177.6 vs
163.9 and 155.9 µmol/L; SEM=5.63; P=0.001). Serum TP was lower on d 110 in pigs
fed T4 compared to T1, T2 and T3 (57 vs 60.5, 59.3, 61.1 g/L; SEM=1.62; P=0.02). On
d 110, serum AST tended to be lower in pigs fed T2 compared to T1 (37.2 vs 53.5
U/L; SEM=4.01; P=0.06). Although statistically significant differences were found,
values remained within the normal ranges for pigs of similar age and weight. No
parameter was consistently affected throughout the study; therefore changes
detected are unlikely to be of clinical importance. This study shows no adverse
effects of feeding Bt GMm to pigs between weaning and slaughter on serum or urine
biochemistry and should help to assure consumers as to the safety of Bt maize.

An investigation into human-centred peer-support education systems
through ICT and new media for students with Specific Learning Difficulties Department of Computing, Mathematics and Physics
Email: [email protected]
Abstract:
Often referred to as a Learning Disability or Disorder, Specific Learning Difficulties
(SLD) are ‗a diverse group of conditions that cause significant difficulties in
perceiving, processing and/or producing auditory, visual and/or spatial information.‘
(TCD, 2010) An SLD is not an intellectual or general learning difficulty: students
with SLDs are of average or higher intelligence that are prevented from performing
to the full extent of their capabilities by conditions outside of their control. The
conditions cover a wide range of issues, such as Dyslexia and the Autism Spectrum
Disorders. People living with SLDs tend to suffer from related stigma, both self- and
externally-generated. In an information-heavy setting, students with SLDs are at a
natural disadvantage, academically, technically and professionally. With the drive to
create a knowledge-based economy and the growth of social media, these students
are at risk of being left even further behind.
The overall research objective then is the development of actionable education
frameworks, self-sustaining peer-support networks and independent learning
strategies through ICT for students with SLDs and similar non-traditional third
level populations. Since priority must at all times remain on furthering the growth
of the students rather than the hardware or software, the most effective recourse in
working towards joint optimisation of both individual performance and system usage
would be to follow the approach and principles of socio-technical systems. This will
be examined through the domains of integration, communication and imagination,
operating initially on a social and academic level, but with a view to moving towards
applied and professional expression of same. In addition to the enhancement of
academic performance, the research aims to aid in the development of student
familiarity and proficiency with ICT, reduce the stigma of SLDs, and promote their
resilience and retention. While designed with Third Level and Adult Education
institutes in mind, it also bears the potential to be adapted for Second Level
Education.
As this research is ongoing at present, final results and findings are pending.
Keywords: ICT, SLD Peer-Support Networks.

Continuity and Change: narratives from inside modern Irish families Department of Applied Arts
Email: [email protected]
Abstract: This research focuses on families in modern Ireland. Families are becoming
increasingly diverse, and family forms have changed dramatically recently, there are
significant increases in the number of separated and blended families (Fahey 2010)
While there has been a number of quantitative studies on childhood recently,
(National Longitudinal Study of Children 2009, Barnardos 2007), there has been
little in- depth sociological enquiry about what it feels like to spend time in a family
(Corsaro 1997). Family represents a constructed quality of human interaction or an
active process rather than an object of detached social investigation (Morgan, 1999).
This qualitative study explores what life is like in Irish families today and places
special emphasis on listening to the voices of children in the family. This inclusion of
children‘s voices in the research process recognises current trends in sociology to
‗rediscover‘ childhood (Corsaro 1998). Within the new sociology of childhood, children
are seen as competent social actors able to contribute their views to the research
(Green and Hogan 2005). Joint story telling is an important part of the culture of
each family, it is how families organise their experiences and make them
meaningful. This study, therefore, explores which aspects of spending time together
are most significant for families and how families spend time together and what
spaces they use; sitting around the kitchen table or chatting while commuting (Urry
2007) Furthermore one of the main aims of the research is to discover whether
certain rituals and routines are unique to each family, or share common themes with
other families (Fiese 2006). Twelve families were interviewed, forty five participants
in total both children and adults. Sensitive ethical considerations about interviewing
children were considered, and all children were interviewed with their consent and
their guardian‘s consent. Each family was interviewed together in their own homes.
This naturalistic setting facilitated the construction of family stories by the
participants, a key focus of this research. The interviews were recorded and
transcribed with the families‘ consent and these transcripts are currently being
analysed. It is anticipated that this study will make an important contribution to the
development of family policy and professional practice in the area of children and
families. In addition emergent themes of time spent together in families will be
useful in socio political debates concerning the rights of children and work life
balance debates in Irish social and working society.

Low cost sensor based on the Quartz Tuning Fork Department of Engineering Technology
Email: [email protected]
Abstract:
The quartz crystal tuning fork shows great potential as a mechanical mass sensor.
Recent work demonstrated that a change in resonance frequency could be used to
measure mass changes in the low nanogramme range [1,2]. This method of mass
detection relied on the use of sophisticated electronics and lock-in detection
techniques to determine changes in resonance frequency following loading of the fork
with polystyrene beads. This poster will outline a novel approach to mass detection
that circumvents the requirement for sensitive and expensive electronics to produce
a truly low cost method of mass sensing. In principle the fork can be connected in a
self oscillating circuit such that the fork will oscillate at its resonance frequency.
Breaking the feedback in the self oscillating circuit allows the recording of the
damping coefficient of the tuning fork. The applications of Fourier techniques allow
the resonance frequency to be determined. The method provides a direct low cost
measurement of the changes in quality factor and resonance frequency. We will
present early stage results from this work and will discuss how the technique may
be used to fabricate low cost sensors for biomedical and environmental application
through the integration of molecularly imprinted media with the arms of the tuning
fork.

Application of Genetic Algorithm to Maximise Clean Energy usage for Data
Centres Telecommunications Software & Systems Group
Email: [email protected]
Abstract:
Following the huge growth in usage over the last 10 years, the Internet has become
a critical business and social tool. In the future however, this popularity will
continue to rise, with the Internet evolving into a full scale distributed service
platform, offering a plethora of services from communications to business,
entertainment and much more. These services will be more dynamic and
sophisticated providing a range of complex capabilities. However, this dynamic
service environment will lead to overwhelming management problems if not dealt
with adequately. At the same time, society is now acutely aware of the significant
energy burden the communications industry is becoming. The data centres housing
these services are seeing their energy consumption increase proportionally, now
leading researchers to actively search for solutions to improve the energy efficiency
of data centres.
With these two trends in mind we propose a biologically-inspired service framework
that supports services intelligently solving a number of management problems. In
particular we use this framework to address the new, emerging problem of a
sustainable future internet. We propose a green solution that makes data centres
and services prioritise the usage of clean, renewable energy sources. The solution
allows data centres to share information regarding renewable energy and cooling, in
order to exploit variance between different countries energy and temperature
profiles by moving services between data centres. We then employ an evolutionary
genetic-algorithm to find the optimal placement of these services on the data centres
in terms of maximising renewable energy usage.

Biotransformations using nitrile hydrolysing enzymes for stereoselective
organic synthesis Department of Chemical and Life Sciences
Email: [email protected]
Abstract:
Pharmaceutical research and manufacturing is increasingly turning to biotechnology
for new efficient routes to complex targets. Biocatalysis is rapidly evolving in organic
synthesis, the historic backbone of the pharmaceutical industry, offering advantages
for green technology and stereoselective control. Ireland is a major player in the
global pharmaceutical industry and Government policy is to grow
pharma/biopharma RandD to protect the sector. Research in this area will generate
novel green technology with key industrial applications and industrial
collaborations.
Nitriles and carboxylic acids are widely used as intermediates in the fine chemical
industry due to their versatility of transformations. Biotransformation of nitriles,
either through a direct conversion from a nitrile to a carboxylic acid catalysed by a
nitrilase or through the nitrile hydratase catalysed hydration of a nitrile followed by
the amide hydrolysis catalysed by the amidase, have become the effective and
environmentally benign methods for the production of carboxylic acids and their amide
derivatives (2).

2. Can the bacterial isolates be used for the production of enantiomerically pure
pharmaceutical actives and intermediates.

WIT Research Day 2011 Book of Abstracts
The 256 nitrile-metabolising bacterial isolates within the PMBRC were isolated and
studied for different streams of work. The initial work in the laboratory ensured that
fresh, working cultures and duplicate archives stocks of all isolates were generated
and maintained to serve the duration of this project. The isolates were grown in rich
medium (LB broth) and stored in duplicate, using microtitre-based high-throughput
growth techniques. The bacterial isolates were first subjected to toxicity studies with
the nitriles of interest. By attempting to grow the different isolates in rich medium
in the presence of the relevant nitrile, any isolates that are sensitive to the nitrile
and cannot grow in its presence can be determined. The biocatalytic activities of the
isolate library were then tested with a selection of pharmaceutically important
nitriles as detailed below: 3-hydroxyglutaronitrile, 3-hydroxybutyronitrile and 3-
hydroxy-3-phenylpropionitrile as these enantiopure -hydroxycarboxylic acids and
their derivatives are important precursors for the synthesis of natural products and
pharmaceuticals (for example: - hydroxycarboxylic esters may be to prepare
intermediates of β-lactam antibiotics).
Currently work is underway to develop methods by which the biotransformation
may be monitored using a range of various techniques, including high performance
liquid chromatography (HPLC) to monitor the conversion from nitrile to acid, chiral
HPLC to measure enantioselectivity, gas chromatography to measure those
substrates which may not be monitored by ultraviolet detectors. Following screening
for conversion and enantioselectivity, the substrates will be modified by the addition
of substituents to enhance enantioselectivity.

A method for producing atomically sharp force sensors for use in a novel
photoconductive atomic force microscope Department of Engineering Technology
Email: [email protected]
Abstract:
The motivation behind this project is to design, manufacture and test a novel atomic
force microscope (AFM). In doing so I hope to achieve a multifunctional instrument
which will aid in the development, production and testing of organic photovoltaic
solar cells (OPVs). The novel AFM is required to operate in AFM, STM (scanning
tunnelling microscope) and photoconductive AFM mode (pcAFM). Traditionally
efficiency measurements of OPVs were based on macroscopic area measurements
however these measurements cannot be truly related to the nano-scale properties of
the device. Crosstalk between the sample illumination source and the laser feedback
system used in traditional AFM can make experimentation difficult resulting in
inaccurate results and frequent tip crashes.
A Quartz Crystal tuning fork equipped with an atomically sharp gold tip will act as
the force sensor within the novel AFM. Tuning forks are used as they have an
extremely high quality factor, they are mass produced for use in wrist watches
which make them extremely cheap and they can be electrically driven to oscillate at
their resonant frequency. When the oscillating tuning fork and tip assembly
approaches the sample under test, surface forces acting on the tip modify the
resonance frequency of the tuning fork. Control of the tip sample distance as the tip
is scanned across the sample surface maintains the oscillation of the tuning fork.
Recording of the tip sample distance control signal provides a map of the underlying
surface. The sensitivity and resolution of the AFM will depend on the properties of
the tip attached to the tuning fork. Producing atomically sharp tips is an extremely
difficult process, more specifically the transfer of the etched tip to the tuning fork.
To over-come this problem a variation of the ―Double Lamelle Drop-off Technique‖
[1] of tip etching has been developed. This method allows the electrochemical etching
of 20 micron gold wire attached in parallel to one of the tines of the tuning fork. In
this method the gold wire which extends beyond the tine of the fork is passed
through a platinum ring and a drop of CaCl electrolyte solution is added to form a
meniscus around the ring producing an electrolytic cell, a current is applied and
etching commences.
55
WIT Research Day 2011 Book of Abstracts
Preliminary testing confirms the production of reasonably sharp tips with a
relatively small mass which was unobtainable using previous methods. This is
largely attributed to the elimination of human interaction with the tip post etching.
AC and DC etching of the gold wire can be optimised to provide atomically sharp
probes for AFM measurements.
This poster will provide an early stage assessment of the new technique for high
quality tip etching.

Integration of OpenCL and OpenMPI to Provide Distributed
Supercomputing Department of Computing, Mathematics and Physics
Email: [email protected]
Abstract: Moore's Law defines that the number of transistors on a processor increases every
18 months. Increased application performance resulted from increasing the number
of transistors on the chip and increasing the clock frequency. Sequential code would
execute faster without any changes to code design. The failure of processor
manufacturers to increase clock frequency has led to the emergence of lower clocked
chips with multiple identical processing cores. Parallel programming is now required
to realise increased application performance in future. This issue of multi-core
processing has evolved with emergence of new heterogeneous processing
architectures. Architectures such as graphics processing units (GPUs from different
vendors), IBM Cell Broadband Engine (CBE) etc. implement non-standard
programming models, requiring specialised algorithm development in order to gain
efficiency. This creates challenges in terms of software portability, optimisation and
maintainability. The Open Compute Language (OpenCL) specification was
introduced by Khronos with the aim of addressing this problem. OpenCL defines a
single programming model that can be implemented on any device supporting the
specification. Devices that support the OpenCL specification implement separate
compilers for OpenCL that optimise for their respective architecture.
Parallel programming models can be used to implement computational patterns.
Examples of computational patterns include structured/unstructured grids for
approximating solutions to differential equations arising from the study of natural
phenomena (fluid flow, structural analysis, heat transfer etc.), state machines to
model the interaction of complex systems, graph traversal algorithms to search for
optimal paths in graphs etc.
The focus of this research is to examine the implementation of computational
patterns on heterogeneous processing architectures using OpenCL. Relative device
performance characteristics, including memory, clock speed and OpenCL specific
characteristics will be examined to develop performance metrics for a device. The
aim is to use the performance metrics of the devices as a basis to develop an
optimisation algorithm. This algorithm has the aim of efficiently distributing the
workload related to the computational pattern involved. A programmer will be able
to define a problem using computational patterns and execute it on a number of
heterogeneous processing architectures.

Maintaining User Privacy in Location Aware Mobile Services Telecommunications Software & Systems Group

Abstract:
Mobile contexts of use vary a lot, and may even be continuously changing during
use. The context is much more than location, but it difficult to identify. Location
information is becoming an integral part of different mobile devices. Current mobile
services can be enhanced with location-aware features, thus providing the user with
a smooth transition towards context-aware services. Services on mobile devices have
large potential due to the very personal and intimate nature of the devices and high
targeting possibilities. Potential application fields can be found in areas such as
travel information, shopping, entertainment, taxi services and advertising. Most of
the service providers (sellers) consider location aware technology a high yield
revenue stream.
One major concern about consumers‘ adoption with these new services lies in privacy
concerns of the users of these services. In most cases, the privacy issues prevent
people from fully embracing these services. Location disclosure due to insider
attacks at the service provider side is a privacy concern for most of the consumers,
where an employee of the service provider compromises the confidentiality and
integrity of the collected data. A Common requirement for privacy aware consumers
is to detect nearby services without revealing their private position. Existing
solutions for this problem rely primarily upon the use of heavily cryptography
protocols, and as a consequence more computing resources are required (e.g.
processing power and bandwidth).
In this poster, we investigate the privacy issues faced by people in sharing their
location information on location aware mobile services (LAMS). We propose an
approach for protecting privacy in location LAMS, the proposed approach provides a
secure data collection schema that sanitizes the data prior to transmission to LAMS.
By adjusting only two parameters, the user is able to choose to increase resources
consumption efficiency or privacy level. This sanitization schema allows the user to
make sure that the data do not leave his/her system until it is properly secured. We
build a prototype for this approach and discuss parameters influences. We run
experiments to test the efficiency of our approach and present the impact of
parameters variations.

Synthetic Molecular Receptors for Steroid Sensing and Release Department of Chemical and Life Sciences
Email: [email protected]
Abstract:
Molecularly imprinted polymers (MIPs) are materials that contain sites or cavities,
which are receptive to a specific molecule or group of molecules. This recognitive
ability is designed into the polymer by the preparation of the polymer in the
presence of the target molecule.
Corticosteroids are pharmaceutically relevant compounds and the focus of this
research is the development of polymeric materials capable of selectively recognising
and differentiating between a range of structurally similar corticosteroids using the
technology of molecular imprinting. These polymers are to be employed as sensing
platforms, such as a quartz crystal microbalance, where they could selectively sense
the steroids in complex biological matrices or drug delivery platforms where the
materials could be used to enhance the targeting and release profiles of the steroids.
To this end, a number of functional polymers have been synthesised in two different
formats, bulk monolith and polymeric microspheres. Microspherical particles have a
range of advantages over bulk material, including ease of synthesis, control of
particle size and mass transfer. These polymers have been synthesised in a range of
solvents and using a number of monomers. A high degree of control has been
obtained for the synthesis of microspheres with sizes between 1-10 µm achieved.
Both bulk and microspherical polymers have been tested using High Performance
Liquid Chromatography (HPLC) and have been shown to selectively recognise
steroids in aqueous solutions.
Keywords: Functional polymers, drug release, sensors.

Deconstructing the Knowledge Concept for Knowledge Transfer Efficiency Department of Management and Organisation
Email: [email protected]
Abstract: A dominant theme that continuously appears to emerge from knowledge literature is
that, knowledge transfer must occur ―frictionlessly‖, hence the importance of
identifying major factors affecting knowledge transfer efficiency. Although
knowledge transfer has received considerable attention in recent years (Lubit, 2001)
and the major determinants affecting its efficiency have been identified (Pérez-
Nordtvedt et al, 2008), knowledge transfer is still proving problematic (Szulanski,
1996; Kwan and Cheung, 2006).
Historically, knowledge is either explicit or tacit (Connell et al, 2003), and the
literature suggests methods for transferring both types (Kwan and Cheung, 2006).
It is widely agreed that explicit knowledge is relatively easy to transfer, as it is
codified, while its counterpart tacit knowledge remains problematic to transfer
(Lubit, 2001; Stenmark, 2001; Haldin-Herrgard, 2004). For Styhre (2004), the core
of the issue is that tacit knowledge holds too many meanings as it is used as an
umbrella term to describe all types of non-codified knowledge; consequently it is ill-
defined and there is no consensus on its characteristics (Howells, 1996; Castillo,
2002; Haldin-Herrgard, 2004: Meyer and Sugiyama, 2007). There is emerging
recognition that knowledge is not polarised, as proponents of the category view of
this dichotomy believe, instead various types of knowledge exist along a graded
continuum which has explicit and tacit extremes (Kogut and Zander, 1992; Leonard
and Sensiper, 1998; Jasimuddin et al, 2005). Simply stated, an organisation needs
to identify the types of knowledge it possess before it can choose an appropriate
method of transfer (Haider, 2009). However few studies have investigated the
different types of knowledge that exist along the continuum. A rich typology of
knowledge would be beneficial in clarifying the knowledge concept (Johnson et al,
2002) and it would allow for the development of more appropriate knowledge
transfer methods, and this is the core objective of this research.
Therefore, the purpose of his study is to deconstruct the knowledge concept into
specific categories and to identify the most efficient knowledge transfer mechanism.
A synthesis of knowledge and knowledge transfer literatures is utilised in order to
investigate this studies overarching research objective.

Towards a framework of understanding restoring actions during the
stages of dissolution in inter-organisational relationships Department of Management and Organisation
Email: [email protected]
Abstract:
The majority of inter-organisational research attention has focussed on the positives
of developing successful relationships and not on the negatives of managing them,
resulting in less attention on conceptual development and empirical evidence related
to problematic relationships facing dissolution (Holmlund and Hobbs, 2009). Indeed
the marketing literature on dissolving relationships appears disjointed with
separate studies focussing on the reasons why relationships end (Keaveney, 1995;
Perrien; Paradis and Richard, 1995) or on the processes of dissolution (Ping and
Dwyer, 1992; Halinen and Tahtinen, 2002) or on the strategies for disengagement
(Alajoutisjarvi, Moller and Tahtinen, 2000; Giller and Matear, 2001) but with scant
attention to the restoration of a relationship once it has entered the dissolving stage
(Salo, Tahtinen and Ulkuniemi, 2009; Tahtinen and Vaaland, 2006). The few studies
that exist have focused on the process of recovery (Salo et al., 2009; Tahtinen et al.
2007) or on the analysis of the attenuating factors influencing recovery (see Vaaland
and Tahtinen, 2003; Tahtinen and Vaaland, 2006), yet they have not linked recovery
actions to each stage of the dissolution process.
It is our argument that dissolution is a process rather than a single decision and
repair can occur at any stage, although it may have different objectives at different
parts of that process (Duck, 1984). Moreover, the restoration process cannot progress
if either party is confused regarding the reasons for breakdown (Halinen and
Tahtinen, 2002; Tahtinen et al., 2007). Similarly, the actions and reactions of
individuals affect the outcome of the process (Hirshman, 1970; Rusbult, 1982) by
either pushing the relationship towards dissolution or attempting to repair it.
Using a qualitative methodology through the use of multiple case studies, the
overarching aim of this study is to create an integrated framework of restoring
actions during each stage of the dissolution process but also including the factors
leading to dissolution and the responses to dissatisfaction. In pursuit of this aim this
research will involve the analysis and exploration of the actions and reactions of
individuals in order to gain a complete understanding of the total process.
62
WIT Research Day 2011 Book of Abstracts
This research attempts to close a significant gap in the literature concerning
relationship recovery by developing a holistic view of the process which has not been
undertaken to date. The study will make a theoretical contribution to the literature
thereby extending research on recovering inter-organisational relationships.
Relationship dissolution represents a huge loss both financially and psychologically
for firms.
If relationships are in disorder they run the risk of lost development and growth and
ultimately sustainability. From a managerial perspective, it is necessary to
understand the reasons how relationships can become dysfunctional and in turn
what strategies can be used to restore them. A greater understanding could help to
rebuild or maintain the relationship as a whole or in the development of future
relationships.

Development of a wind energy prediction tool Department of Engineering Technology
Email: [email protected]
Abstract: Wind is a bountiful source of energy, especially in Ireland. Some of the highest winds
in Europe are consistently in and around Ireland, especially in western regions.
However, wind is also extremely variable in amplitude, ranging (at any given height)
from 0 to as much as 25 metres/second. As the power in the wind has a cubic
relationship with wind speed, even minor speed fluctuations can result in significant
power variations.
The Irish national demand for electrical power is itself also variable, varying by time
of day, day in the week, time of year and weather. The amount of electrical power
generated whether from wind or conventional fossil fuels must always meet the
national demand, if electrical blackouts are to be avoided. Incorporating the volatile
source of electrical power from wind is therefore quite a challenge, a challenge that
will increase over the next nine years, as the amount of electrical power from wind is
expected to increase about fourfold from the present figures. The ability to predict
the likely wind strength is essential, especially if possible by several hours in
advance. Such advance warning allows for conventional power plants to prepare to
increase or decrease output, or, as seems likely to be at least part of the ultimate
solution in nine years time, to plan the release of stored energy (or vice versa the
storage of energy) from pumped storage facilities.
This work reports on the development of a wind prediction model, based on actual
wind data gathered over 18 months here in Waterford. The is statistically data
analysed to confirm correct measurement performance and presented in the (for
wind) conventional form of the Weibull distribution as well as monthly box plots to
confirm site specific mean, median and outlier wind velocities. The direction
information is presented in the form of a wind rose. The data is voluminous with
36,000 data points per sensor per annum (there are 4 sensors in this case and, as
mentioned earlier, 18 months of data.
The initial analysis is also useful in terms of analysing available energy for the site,
but of little value in calculating future wind values. A model is presented of a
temporal analysis of wind data so that future wind values may be predicted with
definable confidence levels.

The eventual computer realisation of the model is presented using the R statistical
programming language. R was chosen as it easily permits the statistical analysis of
the wind data, without discarding the time element associated with each reading.

The role of intrinsic residual stresses in the wear performance of PVD tool
coatings Department of Engineering Technology
Email: [email protected]
Abstract:
Physical Vapour Deposition (PVD) provides a convenient method to deposit hard
wear resistant coatings onto tooling surfaces. The use of (Ti,Al)N coatings as mono
or multilayered structures has increased significantly in recent times. When a
coating is deposited onto a tool at elevated temperatures and cooled to room
temperature, the thermal expansion mismatch between coating and the tool
substrate results in thermal residual stresses.
Residual stress can be defined as ―the stress remaining inside a component or
structure once all externally applied forces have been removed‖. There are many
types of residual stresses some of which are beneficial to the normal operating
component conditions others can be detrimental. Excessively high compressive
stresses may result in de-lamination or de-cohesion of the thin PVD coating,
particularly at sharp edges resulting in the deterioration in wear resistance at
critical locations. Typical residual stress levels are on the order of 1-3GPa for a PVD
ceramic coating on a metal substrate.
Further stresses arise due to the growth of the thin film on the substrate and are
normally called intrinsic growth stresses. These are mainly due to the controllable
coating parameters used in depositing the coating or due to chemical reactions and
phase transformations occurring during the process.
The poster will introduce the issue of intrinsic growth stresses and outline the
controllable coating parameters that can be adjusted to alleviate these stresses.
Early stage X-Ray Diffraction (XRD) results will be presented to show the effects of
coating parameters on the development of intrinsic stresses in the coating. The
possibility to mitigate these stresses using stress relieving operations such as Argon
ion bombardment with bias voltages up to 200V will be discussed. Determining the
most effective point to apply this stress mediating technique is important in
developing high quality wear resistant coatings. The Argon ion impact must be
controlled so as not to detrimentally alter or contaminate coating chemistry.

Optimizing Dynamic Composition of Bayesian Networks for Context
Sensing and Inference Telecommunications Software & Systems Group
Email: [email protected]
Abstract:
Breaking Bayesian Networks (BNs) for context inference from sensor networks into
Bayeslets is a proven approach for optimising performance in resource constraint
ubiquitous computing environments. Context inference with Bayesian Networks
faces the challenge that the related costs (inference time, memory consumption)
grow exponentially with the number of components, as it is NP hard. To minimise
evaluation time, the BN to be evaluated has to be minimised. Automatic selection
and composition of relevant Bayeslets would allow for this. Therefore, this research
investigates optimisation approaches which evaluate the added value of using a
particular Bayeslet versus its cost.
To decide whether to connect two (or more) Bayeslets, the utility of the additional
information has to be determined and compared to the costs of the connection, which
gives us a Net Expected Utility. In utility theory the term utility is defined by the
value a piece of information provides to the system. Evidently, this value strongly
depends on the usage of the information. The utility of an additional piece of
evidence can be quantified by the difference between the utility with the additional
evidence and without the additional evidence.
This work proposes two different utility functions: a probability‐based utility
function based on logarithmic growth would be equivalent to Shannon‘s Mutual
Information; a decision‐based utility function that maximizes the expected utility of
possible actions is equivalent to the Value of Information (VoI). Mutual Information
has to be normalised and the costs for integration have to be subtracted, so that the
candidates for the decision criterion are the Net Normalized Mutual Information
(NetNI) and the Net Value of Information, NetVoI. NetVoI takes into account all
available information at request time, is therefore advantageous over NetNI.
However the design of the utility function to reduce uncertainty in the target
random variable of the Bayeslet is challenging.

Engineering a Scalable Group Management Component for Open Federated
Social Networking Department of Computing, Mathematics and Physics
Email: [email protected]
Abstract:
Group communication offers a means for resource sharing and collaboration, often
delivered through diverse technologies. One of the technologies, Instant Messaging,
traditionally took the role of a facilitating service within such communities. Driven
by a flexible XML based protocol, XMPP, instant messaging has developed
functionality to a point where it can be considered a standalone group
communication medium. The nature of the protocol allows for server to server
federation, paving the way for the development of an open-source federated social
network. End user control over the privacy and visibility of data within their social
network can be a reality. The core protocol itself contains the building blocks to
bring about this paradigm shift, but the scalability, particularly in relation to group
formation and the consumption of media based services, has yet to be achieved. This
work presents a change of design philosophy, opting to embrace asynchronous or
―non-blocking I/O‖ techniques, as a potential solution to the scalability issue.
Marrying this technique to a component based approach, allowing for the
abstraction of the group management capabilities from the core protocol, a scalable
solution is possible. The initial scalability tests show startling results and are
presented here for consideration.

Designing and analysing tourism service systems - bridging the gap
between front and backstage activities Department of Management and Organisation
Email: [email protected]
Abstract: Continuous growth in services has led to the development of innumerable models
and constructs measuring different facets of service systems and map processes
(Shostack, 1987; Parasuraman et al., 1988; Cronin and Taylor, 1992; Cai, Chung, Su,
2008; Spraragen and Chan, 2008). However, the models that exist provide only a
partial view of the whole service system and tend to ignore the interconnectivity
between back and front stage activities (Teboul, 2006; Kim and Kim, 2001). Indeed,
a substantial body of the existing theory has focused solely on front stage activities,
contributing to the domineering front stage mindset among tourism practitioners
(Teboul, 2006). Traditional concepts focus on the determination of quality at
customer touch points and discount the importance and support of the backstage
activities (Teboul, 2006; Kim and Kim, 2001).
Theory suggests that if practitioners can effectively and efficiently design their
service systems by bridging front and back stages, maximum system performance is
achieved (Glushko, 2009; Waring and Bishop, 2010). However, effective integration
of front and back stage activities remains a central dilemma for most tourism firms.
Drawing from the theory of Waring and Bishop (2010) and Glushko and Tabas,
(2009), difficulty stems from opposing characteristics intrinsic to the front and back
stages. These divergent characteristics can stimulate conflicts within the system
(Isaccs and Walendowski, 2001; Glushko and Tabas, 2008/2009). Without research
that delves into ways to effectively bridge the front and the back stages for
practitioners, conflicts will remain and service systems will not be operate to their
full potential.
Although numerous authors have acknowledged the benefits of bridging front and
back stage activities, scant research attention has been given to the issue (Glushko,
2009; Waring and Bishop, 2010).This significant gap in the literature has serious
consequences for practitioners as it causes them to view their service system as a
group of unrelated events, rather than a constellation of processes (Bitner et al.,
2008). Therefore benefits of service design will not materialise in practice.
Essentially this represents a ‗green field‘ for academic research.
69
WIT Research Day 2011 Book of Abstracts
Therefore the purpose of this poster is to conceptualise the current literature to
develop a holistic service design model that integrates back and front stage
activities. Due to the scarcity of research, it is perceived that our ongoing study will
contribute substantially not only to academia but also to practice in that it will allow
tourism operators to optimally deploy service processes and practices through a
systematic, critical and comprehensive examination of a systems process. The poster
will also highlight key areas warranting investigation going forward.

The Amalgamation of Acute Psychiatric Services in the South-East of
Ireland: A Retrospective study Department of Nursing
Email: [email protected]
Abstract:
The study aims to explore organisational issues, which are associated with the
amalgamation of two acute psychiatric services in the South-East of Ireland.
Following a thorough investigation of the literature surrounding service mergers,
organisational issues emerge as a prominent concern. Services have engaged in
domestic and international mergers over the last few years in order to match the
macroeconomic trends operating worldwide and more recently to cope with the
current global financial crisis. The national Government policy document A Vision
for Change (2006) highlights the importance of closing all psychiatric institutions, in
an effort to enhance a community-based model of care, modernisation of mental
health infrastructure, thus reducing stigma for service users. Therefore, considering
acute psychiatric services will continue to amalgamate in the near future, complying
with the policy guidelines, organisational issues remain a priority in order to achieve
successful and efficient service mergers.
In the event of organisation amalgamations not being carried out effectively, the
Irish health care system will suffer serious consequences in relation to improvement
of care for service users and in terms of financial value. Thus it is now evident that
finance alone will not improve the system; rather a concentrated effort must be
made in order to ensure a responsive and efficient service (Downey-Ennis and
Harrington 2002). This study would target healthcare leaders planning organisation
amalgamations and those embarking on a smaller-scale integration of services. In
addition, there are very few ―how-to‖ guides for successful organisation mergers in
the national and international literature. Therefore, this study would aim to be of
benefit to leaders, by sharing the experiences of the Waterford/Wexford mental
health service.
A case study design will be applied to best meet the requirements of the research.
The study will purposively target and recruit individuals, who have dealt with the
Waterford and Wexford amalgamation process to date. Both cases being Waterford
and Wexford will be interviewed using a semi-structured framework to gain an in-
depth understanding of the organisational issues, which have affected the merger
process.

Collectively, the data gathered will address the research objectives of the study as
well as contribute to the conclusions drawn from the study. Finally, the Miles and
Huberman (1984) approach to data analysis will be employed, drawing conclusions
on the organisational issues surrounding the merger process within the specified
mental health setting.

A MIMO calculation involving Narayana triangles and Riordan arrays Department of Computing, Mathematics and Physics
Email: [email protected]
Abstract:
Here we look at the mathematics of one application in the area of MIMO (multiple
input, multiple output) wireless communication through the combinatorics of
Riordan arrays.
Due to the ever increasing popularity of wireless communications and the increased
desire for efficient use of bandwidth, MIMO systems have become an important
research area over the past 10 years as MIMO (multi-input multi-output) channels
offer an increase in capacity compared to single - input single output channels.
We use combinatorial techniques to calculate the MIMO channel capacity. The
techniques involve Riordan arrays and the Narayana numbers. We will briefly
introduce Riordan arrays and the Narayana numbers before finally applying them in
a combinatorial evaluation of the capacity of a MIMO channel.
Keywords: A study of Integer sequences, Riordan arrays and orthogonal

Joint throughput and packet loss probability analysis of IEEE 802.11
networks Telecommunications Software & Systems Group
Email: [email protected]
Abstract:
In the recent years a growth of popularity of wireless networks has been observed.
Different studies propose using such networks to provide transmissions of data
between users, audio and video conferences. Many of such applications are sensitive
to quality of service (QoS) provided by the underlying network. However, a problem
of providing service of guaranteed quality has not been solved yet for wireless
networks. In this work QoS is considered in terms of probability for an average
packet sent through the network to be delayed more then a certain predefined
timeout. This probability is called as ``packet drop probability'' as it is presumed
that transmitting of all such packets is cancelled by the upper layers. Also QoS is
considered in terms of throughput. Thus, QoS is defined as a set of requirements,
where each node requests a connection capable of providing a certain predefined
throughput, while the connection's packet drop probability does not exceed a certain
threshold. Usually wireless networks operate according to IEEE 802.11, which
specifies protocols of physical and MAC layers.
A number of different studies have been conducted on performance of IEEE 802.11
wireless networks. However, questions of QoS control in such networks have not
received sufficient attention from the research community. This work considers
modelling of QoS of IEEE 802.11 networks defined in terms of throughput
requirements and packet loss probability limitations. Random Walk model for
packet delay is proposed. This model allows investigating influence of sizes of
packets being transmitted through the network on the QoS. Extensive simulations
confirm results obtained from the mathematical model. The study shows that
despite throughput growth, increasing size of packets sent through the network may
lead to QoS degradation in terms of packet drop probability. Thus, the study
suggests a trade-off between throughput increasing and packet drop probability
degradation to be considered in order to achieve the best possible performance.

How does a Network influence Market Orientation Capability? Department of Management and Organisation

Abstract: Market orientation is a critical capability (Hooley et al., 1999), which reflects the
ability of the organisation to understand and respond to the needs of the market
(Kohli and Jaworski, 1990) and is primarily concerned with three core elements:
intelligence generation, intelligence dissemination and responsiveness (Kohli and
Jaworski, 1990). Surprisingly, while market orientation is dependent on market
information, the network context for the construct has been relatively ignored in the
literature. There has been some examination of networked market orientation
between firms (Elg, 2002) and more recently individual market orientation within
the firm (Lam, Krans and Ahearne, 2010), but the network as a mechanism for
market orientation has been relatively ignored. This study bridges the network and
market orientation literatures in order to provide more insight into the construct of
market orientation.
While it is intuitive to consider the effect of networks on the development and
efficacy of market orientation, as access to the market insights underpinning market
orientation (Kohli and Jaworski, 1990) depends on external linkages, there have
been very few studies examining the network context (Ritter, 2006). This study is set
within a commercialisation context from the perspective of spin-out companies
within an academic network, with the key research question aiming to investigate
the influence of the university and academic network on market orientation
capability in Irish academic spin-off companies. Studies linking organisational
capabilities and academic spin-offs are rare (Walter, Auer and Ritter, 2006). A
mixed method explanatory design is adopted (Cresswell, 2003) which incorporates a
two phase approach. Phase one involved a national survey of marketing in Irish
academic spin-out companies and Phase two, which is currently underway, involves
an in-depth case study with the aim of understanding the network influence on
market orientation. Upon completion of the study, it is envisaged that the researcher
will advise on the optimum academic network context for fostering market
orientation in academic spin out companies.

IS Implementation and Key Success Factors in Large Scale Telemedicine
Projects in Post-conflict Regions: A Grounded Theory Case Study in Kosovo Department of Computing, Mathematics and Physics
Email: [email protected]
Abstract:
Are post conflict situations uniquely different: Are success factors in complex, large
scale IT projects influenced by the post-conflict situation itself in post conflict
regions?
This research is a grounded theory case study of a selected case organisation.
Information Systems (IS) research in developing regions is limited, and even more so
in post-conflict developing regions. IS in post-conflict, developing regions adds
technical and behavioural issues such as infrastructure, education, funding, and
local political instability to a complicated process. From the limited research, it has
been found that success in implementation in these regions is mixed.
Grounded theory and the single case study research approach are well established
research approaches in Information Systems research (Matavire and Brown, 2008).
Grounded theory is the generation of theory from data obtained during a study, this
data can be obtained through interview, questionnaire, observation, documentation,
images etc. The researcher goes into their chosen field and collects data, until no
new information can be generated from the data (Robson, 2002; Glaser and Strauss,
1967; Strauss and Corbin, 1998). This grounded theory case study is conducted using
interview, images, video and documentation.
This study investigates an organisation which successfully implemented a large
scale telemedicine project. The telemedicine project in Kosovo is a means of
providing basic medical care and medical education to a region which is severely
under resourced. Due to the conflict in the region there was a ten year gap in
Doctors education. The facilities provided by telemedicine, such as teleconferencing
facilities, an e-library, individual units in doctors‘ surgery to consult with each other
through video link, attempts to address these issues.
What emerges from this study are a number of factors which influence the success of
the project: Conflict, Telemed Centre as an Object, External Influences, Local
Politics, Motivation for Telemed Workers, Motivation for Doctors and Leadership,
with Conflict suggested as a major factor. This has implications for understanding
IS Implementation in post-conflict, developing regions.

Managerial innovation: a study of managerial capability for innovation in
tourism micro firms Department of Management and Organisation
Email: [email protected]
Abstract:
The recent economic crisis has led to search at government level, among policy
makers and in businesses, for new strategies and innovations that might underpin
economic recovery and stimulate growth. In an Irish context it is widely argued that
tourism and small to medium enterprises will act as an engine for economic recovery
(IBEC, 2011; Innovation Ireland, 2010; CSO, 2008). Within these sectors micro
enterprises play an important role (Shaw and Williams, 2004). They account for
almost ninety percent of small to medium size enterprises in Ireland (OECD, 2000)
and over ninety percent of all Irish tourism businesses (Reinl, 2008). The academic
literature on tourism and small business research highlights both the urgent need
for strategic innovation and yet the challenges this poses for firms and their
management ((Aldebert et al. 2010; Hjalager, 2010; Shaw and Williams, 2009;
McAdam et al. 2007).
Business innovation has, historically, been widely researched across academic
disciplines. In more recent times there has been increasing interest in the
managerial processes involved in such innovation (Tidd et al. 2005; Krause, 2004).
In particular the impact of management as seen through the concepts of leadership,
inter organisational networks, creativity, and entrepreneurship have been linked to
improved management capability to innovate. Contemporaneously it has been
argued that managers and employees possess their own, often distinct, theories of
innovation (Salaman and Storey, 2002, Barnett and Storey, 2000; Zwick, 2002).
However a review of literature has shown little in the way of the development of an
integrated theory of management capability for innovation in a tourism context.
Specifically writers suggest that the managerial role in strategic innovation emerges
in different ways. Strategic innovation is argued to develop through entrepreneurial
behaviour (Sundbo et al. 2007); networking (Larson, 2009; Novelli et al. 2006;
knowledge management (Shaw and Williams, 2009; Cooper, 2006) and leadership
(Hu et al. 2009).
Generic theories of innovation are criticised for failing to account for the unique
characteristics of both the tourism industry and the small to medium enterprise
sector (Sundbo et al. 2007; McAdam et al. 2007; Scozzi et al. 2005).
78
WIT Research Day 2011 Book of Abstracts
These sectors face unique management challenges and, for this reason, offer an
opportunity both to contribute to a developing field of academic knowledge but also
to offer improved contextual knowledge to industry practitioners.
The proposed research aims to investigate if and how tourism micro firms engage
with creativity in their management capability. It will seek to evaluate the
capability of managers to innovate within the context of the micro firm and to
develop an integrative model for managerial innovation within the sector. It is
anticipated this will enable such firms to benchmark and improve their managerial
capability.
The study will use a qualitative methodology. Qualitative research will be
undertaken with managers within the micro firm sector enabling the collection of
rich data and in depth analysis. The method of in-depth interviews with managers
who act as key informants will be used, enabling investigation of the narratives
underlying managerial theories of innovation (Salaman and Storey, 2009; 2002).
It is anticipated the findings will have both academic, practitioner and policy
implications. A gap in the scholarly literature regarding what constitutes
managerial innovation and how this concept is manifest in the micro firm sector of
the tourism industry will thus be addressed. Equally the findings will have
important policy and practical implications including offering guidance on how
managerial innovation may enable the sector to contribute to economic development;
contributing to the development of tourism management learning programmes and
enabling linkages to be made between government policies in the area of innovation
and the knowledge economy and the specific potential of the tourism small to
medium enterprise sector.

Development of a novel solid biofuel – using solid pig manure Department of Chemical and Life Sciences
Email: [email protected]
Abstract: In Ireland, the expansion of biofuel production has steadily increased over the past
couple of decades. This increase has come about due to the almost near depletion of
fossil fuels. Most biofuels are also carbon neutral and release less green house gases
during combustion than fossil fuels. Additionally, many substances which were once
considered wastes are now being successfully converted into useful biofuels (e.g.
combustion of municipal solid waste to produce electricity). One such waste in
abundant supply is animal manure. It has been utilised as a direct fuel for centuries
and is still being used in third world countries today.
The preferred method of disposing of pig manure in Ireland is to land-spread it for
its fertiliser value. The Nitrates directive (SI 610 2010), and the gradual end to the
transitional arrangements for the application of phosphorus from pig manure means
that increased areas of suitable land are required for land spreading. Pig manure
has been used to create heat and energy by way of anaerobic digestion. However, the
use of manure as a solid fuel is in the initial stages of investigation. Mixing pig
manure and a high carbon content biomass may produce a novel solid biofuel which
could be comparable in value to other existing biofuels.
The solid fraction from separated pig manure (SRM) was composted neat and with
various biomass addendums - sawdust, woodchip, green waste and straw.
Composting the SRM should result in a reduction in moisture content as well as
promote the mixing of the SRM and the biomass addendum. Various mixtures were
composted for 56 days. The effects of this composting process on the chemical
composition of the samples will help determine the suitability of the samples as a
biofuel. The following parameters were determined: moisture, ash, gross calorific
value (GCV), net calorific value, pH, ash forming, corrosive and toxic elements.
During composting the ratio of inorganic/organic species altered, leading to an
increase in percentage ash and subsequently a decrease in GCV. The chemical
analysis from the composting experiments showed that a SRM and sawdust sample
with 6-8 hours composting time had the most suitable chemical analysis for a
biofuel. However, an allied study found that 3-7 days composting was required for
removal of microbiological pathogens.
80
WIT Research Day 2011 Book of Abstracts
GCV was determined to have a similar range to other existing biofuels, e.g. woodchip
– 18-20 MJ/kg. Initial elemental studies have shown that the samples contained
higher amounts of all the metals (K, Na, P, Fe, Cu, Cr and Cd) in comparison to the
CEN/TS 14961:2005 solid biofuels – fuel specification and classes. Further elemental
analysis of Al, Ca, Mg, Mn and Zn is being conducted. The main problem
encountered during analysis was a high ash content in the SRM containing biofuels.
Analysis of samples varying in C/N ratios is underway in an attempt to produce a
product with similar characteristics to traditional biofuels, potentially resulting in
reduced ash content.

Using a community based physical activity (PA) programme as a strategy
to engage vulnerable men to improve their health and wellbeing Department of Health Sport and Exercise Science
Email: [email protected]
Abstract:
The health status of men is closely linked to economic opportunity in society and
those in the lowest socio-economic group carry the disproportionate burden of ill
health and are also less likely to participate in physical activity. In Ireland, only
48% of men engage in some form of regular PA with only 40% meeting recommended
guidelines. Therefore, PA initiatives need to be tailored specifically for vulnerable
men. An 18-week PA programme was developed as one part of a community-based
strategy to improve the health of vulnerable men. The EQ-5D Euroqol Quality of
Life and International Physical Activity Questionnaire (short version) were
administered at baseline, 6 weeks and 6 months. Qualitative observations (week 9
and 16) and interviews with both the participants (n=5) and the facilitator (week 19)
were also used to evaluate the effectiveness of the programme and the impact it had
on men‘s health.
There was no significant difference in total physical activity volume (MET–
minutes/week) and time spent sitting (P>0.05). However, there was an increase in
the mean EQ VAS (visual analogue scale) quality of life rating across the three time
points, from 61.4 at pre-intervention to 78.9 at six weeks and 81.1 at six months.
Men experienced many benefits from participation such as increasing their social
network, reducing isolation, losing weight and positive changes in their family‘s
lifestyle behaviours. Key elements that contributed to the success of the programme
included; removing all cost barriers, avoiding excessive assessments, a tangible and
structured programme, allowing time for social interaction, providing an experienced
instructor, participation of project workers, setting goals as a group and facilitating
regular feedback on the structure of the programme. Despite this, participants did
not have ownership of the programme and this threatened the long term
sustainability of the programme.
This investigation suggests that tailoring PA programmes specifically to the needs of
vulnerable men can be effective in improving their quality of life. Similar projects
should aim to empower participants by involving them in the organisation, planning
and delivery of the programme.

Antibacterial activity of marine bacteria isolated from seaweeds, sand and
seawater Department of Chemical and Life Sciences
Email: [email protected]
Abstract:
Due to the emergence of antibiotic-resistant bacteria, there is a demand for new
antibacterial agents. Seaweed surfaces are colonised by diverse microbial
communities, which play a role in inhibition of predators and biofouling. Therefore,
seaweed-associated bacteria could potentially be exploited as a source of novel
antibacterial compounds. The objective of this study was to examine antibacterial
activity of culturable epiphytic (surface-attached) bacteria from a range of Irish
seaweeds, as well as bacteria from sand and seawater. Samples were plated on a
range of culture media and spore-forming bacteria, known for the production of
antibacterial compounds, were isolated by heating samples to 80 ºC for 15 min prior
to plating.
Initially, more than 6,000 colonies isolated from seven seaweeds, one seawater
sample and one sand sample, were screened for antibacterial activity against
Escherichia coli, Salmonella Typhimurium, Listeria innocua, Bacillus subtilis and
Staphylococcus aureus using an agar overlay method. Nineteen isolates with
antibacterial activity against at least one of these indicator bacteria were isolated
and their activity was confirmed against a range of pathogenic and non-pathogenic
bacteria. All antibacterial-producing bacteria were identified as Bacillus spp. by 16S
rRNA gene sequencing, confirming the genus as an antibacterial producer. The
antibacterial compounds are currently being characterised and data demonstrating
sensitivity to proteolytic enzymes indicate that some are likely to be bacteriocins,
ribosomally synthesised antibacterial peptides. Additional studies examining heat
stability of the antibacterial compounds revealed that some retain activity following
heating to 121°C for 15 min. Overall, this study demonstrates that bacteria isolated
from seaweeds produce compounds with promising antibacterial activity against
pathogens, such as methicillin-resistant S. aureus (MRSA), E. coli and Salmonella.
Future work will involve additional characterisation and identification of the
antibacterial compounds produced by the marine bacteria.

Removal of Salmonella and indicator micro-organisms in integrated
constructed wetlands treating agricultural wastewater Department of Chemical and Life Sciences
Email: [email protected]
Abstract:
The purpose of this study was to investigate the removal of pathogenic and indicator
micro-organisms in integrated constructed wetland (ICW) systems treating
agricultural wastewater. Nine ICW‘s treating piggery (3) or dairy (6) wastewater
were sampled and indicator micro-organisms were enumerated in the influent as
well as the effluent from the first, mid- and final cells. The presence/absence of
Salmonella was also determined and any Salmonella isolates recovered were
characterized. Mean counts of coliform, E. coli and Enterococcus across all nine ICW
systems were lower in the final effluent than in the effluent from Cell 1 (P<0.001).
An antibiotic susceptible isolate of Salmonella Dublin, a bovine-adapted serotype,
was isolated from the influent to one dairy ICW but was not detected in any of the
ICW cells. An antibiotic sensitive Salmonella Dublin isolate with the same
molecular fingerprint was also recovered from the Cell 1 effluent of another dairy
ICW but was absent from the influent and the mid-cell and final effluents.
Salmonella Typhimurium DT104b was detected in the liquid fraction of
anaerobically digested pig manure as well as in the effluent from the first cell and
mid-cell of an ICW treating this material, but was absent in the final effluent.
Molecular fingerprinting by pulsed field gel electrophoresis demonstrated that the
recovered isolates were highly related. However, they had different antimicrobial
resistance profiles, with some highly resistant isolates recovered. In conclusion,
counts of indicator micro-organisms were reduced significantly within ICW, with E.
coli and Enterococcus non-detectable in the final effluent. Moreover, Salmonella,
when present in the influent, was effectively removed.

Richard Henebry (1863-1916): ‘The Forgotten Voice’ Department of Creative and Performing Arts
Email: [email protected]
Abstract: Richard Henebry (1863-1916): ‗The Forgotten Voice‘
Richard Henebry was born in 1863 and pursued a commendable career in the study
and restoration of the Gaelic language. His involvement in the Gaelic revival
aroused his interest in recording Irish traditional music. As a traditional fiddler
himself, he was more than qualified to collect and comment on it. He was the first in
Ireland to collect sound samples ‗in the field‘, using an Edison Phonograph.
Henebry was not content to simply record the existence of the music, he also
analysed it in a new and scientific method. He examined his ‗field‘ recordings using
the latest audio and tonometric methods and technology. He also wrote two books,
Irish Music (1903), and A Handbook on Irish Music (1928). Because of his expertise
in phonology, he used some methods of phonological analysis to examine the music,
thus creating a completely new and novel approach to musicology. Although
Richard Henebry was widely respected by his contemporaries as a Gaelic scholar
and musician, he is largely forgotten today as a music collector and analyst.
The proposed poster will give an overview of the project and methodology. The
project aims to gain a detailed knowledge of the life and times of Richard Henebry
and an understanding of his motivation for collecting Irish music. In addition, it
intends to explore the nature of Irish music in Ireland at the beginning of the
twentieth century, to identify Henebry‘s sources and to gain an understanding of
Henebry‘s theories on Irish music. The poster will highlight the research completed
on the project to date and the conclusions which can be derived from this. This will
include a synopsis of the biographical detail unearthed on Richard Henebry; a brief
evaluation of the influence Captain Francis O‘Neill exerted on Henebry in the area
of Irish music; details of Henebry‘s collection work, primarily in Co. Waterford, and
the identification of his sources; details of the nature and location of the extant
Henebry recordings; and finally an overview of Henebry‘s publications and theories
on Irish music.

Forging a Path For Abstinence from Heroin; A Grounded Theory of
Detoxification-Seeking Among Heroin Users in South East Ireland Department of Health Sport and Exercise Science
Email: [email protected]
Abstract: The need for an increase of community and residential detoxification services in
Ireland has been articulated at national and local level (Mannix, 2006; Corrigan and
O‘Gorman, 2007; Dept. Community, Rural and Gaeltacht Affairs, 2007; Doyle and
Ivanovic, 2010). This study explores detoxification-seeking among heroin users in
South East Ireland, through a classic grounded theory approach. The study
identifies that the main concern of people who are seeking detoxification from heroin
is the desire to get clean from heroin.
There are three responses to this concern, each of which is part of the process of
forging a path for abstinence from heroin. These three responses are; resolving to
stop using heroin; navigating for abstinence from heroin, and initiating abstinence
from heroin. However, not all heroin users when they are concerned with getting
clean experience each of the three afore-mentioned responses. In addition, a
completed process of forging a path for abstinence from heroin does not always end
with long-term abstinence, and is frequently compounded by relapse.
The responses of heroin users to wanting to get clean occur within a subjective
‗resource context‘. When forging a path for abstinence heroin users have varying
levels of the following complex resources; dependence knowledge; treatment
awareness; treatment access, and alliance. A supportive resource context enables a
heroin user to forge a path for abstinence safely, whereby withdrawal is managed
through a detoxification method which is not self-detox. The presence of formal and
informal alliance, as well as a collaborative approach throughout the process of
navigating enable heroin users to seek detoxification-seeking within the formal
treatment sector.
The study has implications for ensuring supportive resource contexts for heroin
users through the development of low threshold services, community-based and
residential detoxification services. The development of such services, with service
user involvement, emerge as the way forward to meet the psycho-social and health
needs of heroin users who are concerned with getting clean, and minimise the risk of
self-detoxification.

The grounded theory demonstrates that valuable insights are gained from studying

become drug-free.

To Investigate the Role of Country Characteristics in the Availability of
Finance for Irish Small and Medium Sized Enterprises Department of Accounting and Economics
Email: [email protected]
Abstract: The financial capital structure of small and medium sized enterprises (SMEs) has
received significant attention, where the idiosyncratic nature of SME finance further
heightens interest within the field (Berger and Udell, 1998). Against this backdrop,
the availability of finance has remained the Achilles‘ heel of small and medium sized
enterprises where conventional wisdom lends credence to stringent financial
impediments (Hyytinen and Pajarinen, 2008). Alluding to the financial constraints
inherent to small and medium sized enterprises, the theoretical framework of Berger
and Udell‘s (2006) recent conceptual model underlines the proposed research,
framing the milieu of the empirical investigation. To facilitate the perusal, the role
of the financial institution structure and the role of the lending infrastructure
(Berger and Udell, 2006) within Irish SME financing are inspected. Lending
credence to the fundamental role of SMEs in an economy, reducing their ‗finance
gap‘ (Harrison and Mason 1996; Tucker and Lean, 2003) forms much of the
motivation for the research.
Dissecting the financial institutional structure into its dimensions of large versus
small banking institutions, foreign versus domestically owned banks, state owned
versus privately owned institutions and market competition (Berger and Udell,
2006), emphasis is placed on the role of foreign versus domestically owned banking
institutions. Given the paucity of studies investigating this element of the financial
institutional structure (Berger and Udell, 2006) and its relevance within the Irish
financial landscape, this reinforces the validity of the research. Furthermore, a
secondary focus will also be placed on large versus small institutions given this
dimension is evident within Ireland albeit less profound. By inspecting this tenet of
research further, lies the scope to advance the empirical contribution outside of the
US context (Di Patti and Gobbi, 2001).
Constituting the lending infrastructure, the information environment, tax and
regulatory environment, legal, judicial and bankruptcy environment and social
environment (Berger and Udell, 2006) will also be evaluated. In particular, scholars
posit a firm‘s financing behaviour is shaped not only by firm factors but
concomitantly by country specific characteristics (Fan et al, 2008).
88
WIT Research Day 2011 Book of Abstracts
Envisaging a change in paradigm, the role of country factors within SME finance
has now progressed to the forefront of research albeit this tenet of literature still
remains in its infancy stage. Given much of the existing studies focus on cross
country analysis (Hall et al, 2004; Daskalakis and Psillaki, 2008) few individual
country investigations prevail, highlighting some of the originality of the proposed
research.
Evaluating the recent conceptual model within Irish SME lending, a mixed
methodology approach is proposed. To facilitate the research questions, the research
orientation will first lend credence to a qualitative approach through the mechanism
of questionnaires and interviews followed by the utilisation of quantitative methods
to reinforce robustness. Originality of the research lies in obtaining a 360 degree
view of Irish SME lending from all key participants i.e. financial institutions,
representatives of the lending infrastructure and SMEs.

Dairyman project - Delivering environmental quality and prosperity by
improving utilization of resources on dairy farms Department of Chemical and Life Sciences
Email: [email protected]
Abstract:
AIM
The objective is to assess the ecological, economic and social performance of the main
dairy regions in NWE, to analyse the needs and opportunities for improvement, and
to encourage and support key stakeholders to optimise their activities and cooperate
together. There are ten regions participating in DAIRYMAN project: Brittany (F),
Pays de la Loire (F), Nord Pas de Calais (F), Southwest of Ireland (IRL), Northern
Ireland (UK), Flanders (B), Wallonia (B), Baden-Württemberg (D) Luxembourg (LU)
and The Netherlands (NL).
WHY?
Climate and soils are excellent for dairy production and there is an extensive local
market for dairy products. Environmental sustainability is generally low: nutrient
and greenhouse gas emissions are high due to the inefficient use of fertilizers, feeds
and energy. This inhibits the ability of these densely populated areas to deliver
services such as clean water or recreational use. Poor utilisation of increasingly
expensive resources threatens the economic viability of dairy farms.
HOW?
There will be cooperation on the assessment of sustainability and needs and
opportunities for improvement and on how to improve dialogue and cooperation
between stakeholders to strengthen sustainability. Intensive interaction with
regional development programmes and projects will create synergies. Experiences
will be exchanged on the process of implementing environmental EU regulations in
regions with high livestock densities and guidelines to optimise that process will be
developed in. Therefore the key actors in policy making in the field of sustainable
agriculture (e.g. the ministries of Agriculture and Environment and regional
authorities) will be consulted and invited for regional and interregional meetings.

EXPECTED OUTPUTS
I will publish papers on N balance, P balance and on the economic results of 21

country for assessing the regional sustainability, management tools of nutrient
management, guidelines for adopting improved nutrient management for the
farmers and for implementing transparent environmental policies for the local
authorities.

Parameterised Gradient Based Routing with QoE Monitoring for Multiple
IPTV Providers Telecommunications Software & Systems Group
Email: [email protected]
Abstract:
Popularity of IPTV (―Internet Protocol TeleVision‖) services, such as Video on
Demand (VoD) and live streaming, has increased tremendously over the last years.
This impacts and increases complexities for managing resources of future
communication networks, in particular when they have to support multiple IPTV
providers, that offer numerous and diversified video contents. Today's techniques do
not support or adapt to this new demand, therefore resource congestions occur when
network activity increases. That impairs dramatically the Quality of Experience
(QoE) which defines the perception of the content' quality as perceived by the
endusers.
The proposed solution is the integration of a QoE monitoring mechanism to new
distributed routing protocol for underlying network that enables IPTV providers to
successfully monitors quality of their streamed contents while maximizing usage of
network resources.
The proposed solution has been evaluated by simulations that show its efficiency in
comparison to standard approaches.

An exploration of the perceptions of pregnant women and their care
providers regarding the provision of antenatal care services Department of Nursing
Email: [email protected]
Abstract:
Ireland currently has the highest birth of the 27 European Union (EU) countries
(ESRI 2008). The increasing birth rates have led to an increase in demand for
maternity services. In Ireland, most maternity units follow the medical led model of
care; limiting Irish women‘s choice for their maternity care to either using private
health insurance or attending the public healthcare system. At WRH, various
different midwifery-led schemes are available for low risk pregnant women, however
according to anecdotal information volunteered by women attending the services: it
seems that a lot of low risk women are unaware of these current options for care.
The main aims of the proposed research are to improve the accessibility and
knowledge of these midwifery led schemes. It is anticipated that the findings and
results of this study will provide the framework necessary to devise an integrated
care pathway from a service and service user perspective, which will enhance the
reorganisation of maternity–led services within the current healthcare system.
It is envisaged that a mixed methods approach is utilised, using a non-experimental
design for the quantitative approach classified as an exploratory survey.
Questionnaires of low-risk women will explore their awareness levels of available
options for care and their views regarding antenatal care services. From a
qualitative perspective, approximately 10-15 semi-structured interviews of health
professionals will provide rich data on the perceptions of health professionals
regarding the provision of current antenatal care services and of the barriers
involved regarding access to care.
Participants will be recruited using a purposive sampling method for both
approaches. Data from the quantitative approach will be analysed using the SPSS
software packages and NVivo 9 will be used to analyse data following allocation into
themes using the Myles and Huberman framework. It is anticipated that the
findings and results of this study will provide the framework necessary to devise an
integrated care pathway from a service and service user perspective, which will
enhance the future reorganisation of maternity–led services within the current
healthcare system.

Abstract: Although destinations have become one of the most popular topics in tourism
research, most of these studies have focused on studying destination marketing and
image (Wang, 2008), or on relating destination performance to the characteristics of
the partners (Bramwell and Lane, 2000) or suggesting approaches to planning and
managing the destination (Dredge, 1999), and comparatively little attention has
been directed at treating tourism destinations as a strategic network (net) and how
that net is managed. The dominant perception within the literature (Prideaux and
Cooper, 2002) is that due to the fragmented nature of the industry, no single
organisation has the capability to manage the wide diversity of tourism offerings at
a destination level. Drawing on the Industrial Network Approach (Hakannson and
Ford, 2002), Strategic Management (Gulatai et al. 2000) and the Dynamic
Capabilities View (Teece et al. 1997), destinations can be viewed as strategic nets
which are intentional structures specifically designed for the purpose of creating an
integrated destination experience (Miles and Snow, 1986; Moller and Svahn, 2003).
However, the benefit to the destination of these strategic nets does not come free.
They require the development of specific organisational capabilities within the
DMO. Gadde and Hakansson (2001) conceptualise that these capabilities centre
around the hub organisation being capable of identifying and understanding market
needs and the network actors required to deliver value for tourists. From a
destination perspective, visioning capability involves an assessment of which
elements the customer requires from the integrated experience offering (Hu and
Ritchie, 1993). However simply having a visioning capability is not enough; the hub
organisation must possess a network orchestration capability in order to
strategically mobilise, coordinate and manage a group of autonomous but
interdependent stakeholders to both co-create a destination experience and
maximise individual firm performance.
In line with Moller and Svahn‘s (2003) assertion that managing a strategic net is
akin to orchestration, this study is adapting and developing the orchestral motif
within the context of an experience destination as a strategic net. The orchestral
metaphor addresses the complexity engendered in the creative process of attempting
to manage a tourism destination network.

Within an orchestral context, the conductor takes a musical score and interprets this
score for an orchestral setting. The conductor then orchestrates the diverse players
so that his/her interpretation of the score is achieved. Applying this to the
examination of management capabilities within a tourism destination context, this
would equate the musical score with the narrative for the destination brand. The
DMO which is responsible for destination planning must communicate this
narrative to the tourism enterprises who are the key players in the destination
network. This can be done through the network visioning capability (Moller and
Svahn, 2003). However, understanding how these capabilities are utilised by a DMO
to intentionally create an experience destination through the formation of strategic
nets has not been studied to date. Therefore, the purpose of this poster is to present
a framework outlining how a DMO intentionally conceptualises and develops a
destination experience.

Changes in soil organic C in a clay-loam soil under permanent and
cultivated grassland in relation to GHG budget Department of Chemical and Life Sciences
Email: [email protected]
Abstract: The United Framework Convention on Climate Change obliges countries, through
ratification of the Kyoto Protocol, to reduce their greenhouse gas (GHG) emissions by
5% during the first commitment period compared with 1990 levels. The article 3.4
allows including C sequestered in ‗sinks‘ to meet emission targets. The aim of this
study was to investigate in permanent grassland (PG) (i) C sequestration in the soil
profile over between 2001 and 2009 (ii) changes in soil organic C (SOC) following
cultivation.
A long term study (2001-2009) was carried out on grass-clover grassland at Solohead
Research Farm, on a poorly drained clay loam soils. The experimental area (22 ha)
was divided into 4 blocks. Each block consisted of 4 paddocks. The blocks were under
typical grassland management mainly used for grazing and for silage production. In
2001, the swards were between 6 and 16 years old.
Soil sampling from the PG was carried out on 5 occasions between 2001 and 2009.
Fifteen cores per paddock were taken to a depth of 90 cm using a hydraulic auger.
Each core was subdivided into 3 depths: 0-30, 30-60 and 60-90 cm and bulked into
one composite sample at each depth within each block. In 2008 one paddock in each
block was ploughed and reseeded. The cultivated treatment (CG) was sampled as
above on 3 occasions during 2008 and 2009. Soil cores were analysed by dry
combustion using a LECO CN-2000. Soil bulk density (BD) was measured in 2001
and in 2008.
The quantities of SOC in each depth section (t ha-1) were determined using soil BD.
A one-way ANOVA (proc mixed; SAS) was used to examine the changes in SOC
under the PG over time. Linear regression (proc reg; SAS) was used to estimate the
annual change in SOC (t ha-1). The SOC (%) under PG and CG were subjected to
ANOVA (proc mixed; SAS).
The SOC (0-90 cm) increased linearly (P<0.05) between 2001 and 2009 at an annual
rate of 5.96 t ha-1. This is an equivalent to the annual sequestration of 21.8 t CO2 ha-
1. Cultivation decreased SOC (P < 0.05) in the upper 30 cm of the soil profile.
96
WIT Research Day 2011 Book of Abstracts
The difference in SOC between PG and CG represented a loss of 30.14 C t ha-1 in the
18 months after cultivation. Assuming that respiration was responsible for the loss,
cultivation resulted in an emission flux of 110.3 t CO2 ha-1. Based on direct
measurement of emissions (Li et al., 2011) and using Life Cycle assessment (Yan et
al, 2011) estimated total annual GHG emissions from Solohead Dairy Research
Farm (52 ha) to be approximately 475 t CO2 eq. These GHG emissions are less than
half of the quantity sequestered into SOC under PG (1134 t CO2)). This has
implications for the national GHG inventory and for the image (in terms of carbon
footprint) of the milk produced on the farm. Further research to better understand
the mechanism of C accumulation and mineralization in the soil at this site is
needed.
Keywords: Carbon accumulation in grassland soils.

A Socio-Technical Study of Information Systems Risks Department of Computing Mathematics and Physics
Email: [email protected]
Abstract:
This is a provisional examination for a PhD study of the socio-technical issues that
have a bearing on the risks associated with using information systems. Traditionally
organisations have taken a purely technological approach to information systems
risk (IS risk). This is due to the traditional separation of business activities from
technology functions within organisations (Halliday et al., 1996). This resulted in an
approach to risk that was theoretically correct but deficient for the needs of an
organisation (Westerman and Hunter, 2007).
Consequently, a number of academics have developed alternative approaches to IS
risk such as Halliday et al. (1996) that proposes a business orientated approach
which emphasises protecting systems to which critical business processes depend.
Alternatively Bandyopadhyay et al. (1999) whom advocates an alternative systems
approach to information systems risk in which risks are dealt with at specific levels
within an organisation.
However effective the aforementioned approaches are, none of them enable
organisational stakeholders make sense of information systems risk. Risk aversion
must be tackled within an organisation. Management must engage and support
smart risk awareness through proper policies whereby risk management and
calculated risk are considered part of doing business (Westerman and Hunter, 2007).
Werlinger et al. (2009) argues that stakeholders often fail to realise the penalties of
not dealing effectively with IS risk. Whilst some research has been done into
alternative approaches to IS risk most still do not factor in the significant
organisational aspects of IS risk. This argument is further supported by Kemp
(2009) whom states that much of the existing research focuses on what is produced
by the different risk frameworks rather then the environment in which it operates
consequently gaps can develop between the framework and the actual security
practices undertaken.

WIT Research Day 2011 Book of Abstracts
Karl Weick‘s (1995) work on sensemaking provides a new sensemaking perspective
on IS risk. Sensemaking is a iterative process whereby people take in stimuli in the
form of speech, new technology or business processes producing actions which in
turn produces new stimuli starting the process again (Stapleton,2001; Seligman,
2006). An important aspect of sensemaking is the question-action orientation
whereby the stimuli cause questions to be asked which is important as often
stakeholders rush to decision rather than focus upon what question is being asked
(Stapleton, 2001). Weick (1995) argues that sensemaking is important in
organisations were ambiguity or uncertainty surrounds an event, he goes on to
argue that it is not about having access to more information but rather the
information currently known about an event may not resolve any
misunderstandings. In the context of IS risk often managers will use certain
assumptions to determine what caused a particular security incident however as has
been stated by Weick (1995) those assumptions maybe incorrect or never met
because the information currently used to support said assumptions maybe
incomplete this has a direct effect on the ability of an organisation to respond IS
risks.

D.I.Y. Divorce - The March of the Lay Litigant
Introduction
Organisations and groups that deal with families in crisis, and researchers and
policy makers need information on what happens in the family courts. The veil of
secrecy that still for the most part lies over Family Law proceedings, has meant that
the public cannot see justice administered publicly. This project seeks to examine
―holistically‖ the Family Law system in relation to Judicial Separation and Divorce.
Methodology
There is a necessity for research and accurate statistical and other empirical data in
this subject area, to form the basis for rational reform. The research will entail the
preparation of Reports, Judgements, Trends and Statistics, based on a
representative ―unit of time‖, (November 2008- July 2012 inclusive), selection of
applications to the Circuit Court in relation to Judicial Separation and Divorce. The
Circuit Court hears approximately 98% of all such cases.
Research finding
Our Family law system is not designed to assist the lay litigant, a significant
number of which are presenting in court without legal representation, which is
hugely problematic both for the court and the parties involved. There is a clear
pattern of financial necessity and lengthy waiting lists for Free Legal Aid, driving
the march of the lay litigant.

Bullying, Communications Media and Adolescence in Contemporary Irish
Society Department of Applied Arts
Email: [email protected]
Abstract: Historically, all new eras of modernisation bring with them both benefits and
challenges, resulting in overall changes in societal order and values (Giddens,
1990:7). Such changes are also accompanied by impacts on our behaviour, and
mutual interactions, both positive and negative. My research intends to provide a
qualitative examination of one of the more negative aspects of human behaviour;
bullying, within the context of how it is conducted by adolescents, through the
medium of communication technology. The focal point of the study will be located
primarily amid the adolescent cohort, and intends to investigate through focus
groups and in-depth interviews, just how bullying behaviour appears to have
adapted to changes within our current digital information era.
Digital technologies have acquainted society with the newest form of social reality,
namely cyber space, and more specifically; the domain of social networking sites
(SNS). In February 2010 ―…Facebook had 426.7million unique visitors …up 68pc
from the year before‖ (Cashin, 2010). This finding is suggestive that the popularity
and convenience of such SNS are no longer a mere novelty; rather they have now
become embedded into modern communication styles.
Communication technologies now offer our young people immense social possibilities
and freedom, especially from adult restriction and/or supervision. For instance
mobile phones, have now become an undeniably necessary part of most young
peoples daily arsenal. Such communication tools are beneficial in supporting social
activity that permits young people to feel connected to their peers. Evidently
however, such accessible social activities can also lend themselves to more sinister
purposes, particularly where the relevant technologies permit its users to
masquerade under the guise of anonymity, disinhibition and infinite exposure
(Kowalski et al, 2008). Technology can and is, being employed in this more negative
fashion, and as with more traditional forms of bullying, cyber bullying thrives on
secrecy. In this context though, it seems important to note that as Bouilton and
Durant remark; ―…harm faced by children on the Internet is a very human harm,
not a technological harm‖ (2008:11).
102
WIT Research Day 2011 Book of Abstracts
We need to bear in mind that what we are witnessing with cyber bullying is the
same aggressive behaviour that drives more traditional styles of bullying, but with
the potential to empower and magnify said aggression through communication
media pathways.
The overall objective of my study will be to establish and generate new knowledge in
the field of cyber bullying within contemporary Irish society, and seeks to contribute
significantly to academic and practitioner knowledge.

Predicting N-fixation in grass-clover pastures 1Animal & Grassland Research and Innovation Centre, Teagasc, Moorepark,
Fermoy, Co. Cork 2Department of Chemical & Life Sciences , WIT
Email: [email protected]
Abstract:
Nitrogenous fertiliser use is endemic in current agricultural production. However,
environmental concerns and the escalating price of N-fertiliser over the last ten
years bring the continued viability of this practice into question. An alternative is to
increase use of biological N-fixing (BNF) plants in agriculture. Irish agriculture is
predominantly grassland-based and white clover (Trifolium repens) is widely
regarded the best-suited plant for increasing BNF in grazed-grassland. However,
quantifying the input of N to farming systems from BNF is a major research goal.
Therefore there is a demand for an effective tool to reliably estimate the BNF input
to grassland from white clover.
Previous literature indicates that BNF is closely related to the amount of clover
plant material produced. Simple linear correlation across multiple experiments
showed a significant relationship (y = 35x; R2 = 0.91; P < 0.01) where y = clover DM
(t ha-1) and x = BNF in herbage (kg N ha-1). However, this is based on data from the
main growing season (spring – late autumn) and does not take into account the
release of N fixed in roots and stolons over the winter period and subsequent uptake
by grass. A correction factor of 1.27 has been suggested to account for N fixed in
roots and stolons. The objective of this experiment was to evaluate the use of the
above linear relationship for estimating BNF from white clover in Irish grassland
over winter.
From 2008 to 2009, 160 plots (each 2m × 8m) were installed on a grass-clover
pasture at Solohead research Farm, (52˚51‘N, 08˚21‘W). Various combinations of
simulated autumn grazing management factors (cutting height, cutting interval and
date of last cut) were assigned to these plots in a randomised complete block design
with 5 replications. Included in the design were grass-only plots with clover
completely.
104
WIT Research Day 2011 Book of Abstracts
Herbage dry matter (DM) production and N-content was measured at each harvest.
BNF was calculated using the total nitrogen difference method:
gggcgc DMNDMNBNF
Where N was N-content of herbage (g kg-1), DM was herbage dry-matter yield (t ha-
1), gc referred to grass-clover plots and g referred to grass-only plots.
The effect of simulated grazing management on BNF was analysed with interaction
ANOVA in SAS Proc mixed and the BNF results were compared to predicted values
from the linear equation described above using SAS Proc reg. Despite the large
variation in simulated grazing management, there was a significant positive
relationship between BNF and clover herbage DM production (R2 = 0.62; P < 0.01)
with 44 kg N fixed per tonne of white clover DM yield. When predicted BNF was
compared with actual BNF using linear regression, a high level of precision was
found (y = 98x; R2 = 0.67). It can be concluded from this study that BNF in clover-
grass pastures can be readily predicted across a wide range of management factors.

Isolation and characterisation of antibacterial phytochemicals from green
and red seaweeds harvested from the Irish coastline Department of Chemical and Life Sciences
Email: [email protected]
Abstract:
The emergence of antibiotic-resistant bacteria, such as methicillin-resistant
Staphylococcus aureus (MRSA), has resulted in a need to identify novel antibacterial
agents. Seaweeds contain a vast array of phytochemicals which are reported to have
a wide range of biological activities, including antibacterial activity. Furthermore,
seaweeds grow in relative abundance along the Irish coastline and are considered a
sustainable natural resource. The aims of this research were, firstly, to examine
antibacterial activity of extracts generated from seaweed species which are
indigenous to the South-East coast of Ireland, and secondly, to isolate and
characterise the compounds responsible for in vitro antibacterial activity. Initially,
56 extracts were generated using a range of solvents with varying polarity and these
were tested in vitro for activity against a range of pathogenic and non-pathogenic,
Gram positive and Gram negative bacteria using a disc diffusion assay.
Twenty five extracts demonstrated antibacterial activity against at least one
bacterial species and two extracts were chosen for further investigation. G2F, an
extract generated from a green seaweed species with a neutral solvent produced
inhibition zones against Bacillus subtilis ATCC 6633 (12 mm) and MRSA W73365
(7.5 mm). Bioactive compounds were separated from the crude extract using a
combination of bioautography, preparative thin-layer chromatography and column
chromatography. These bioactive compounds are currently being identified. In
addition, a second extract R1A, from a red seaweed species also demonstrated a
promising zone of inhibition against MRSA W73365 (18 mm) and is currently being
investigated. This study demonstrates that green and red seaweeds harvested from
the Irish coast contain compounds with promising antibacterial activity which could
potentially be used against human antibiotic-resistant organisms, such as MRSA.
Future work will involve additional characterisation and identification of the
antibacterial compounds found in the extracts displaying bioactivity.

A novel nanohole biosensor Department of Engineering Technology
Email: [email protected]
Abstract: A gold film patterned with subwavelength apertures operates as a highly sensitive
biosensor, suitable for the measurement of realtime, biospecific interactions [1]. This
method of biosensing relies on the phenomenon of the extraordinary optical
transmission of light trough apertures smaller than the wavelength of the incident
radiation [2]. The transmission of light is a plasmon resonance effect that is modified
by changes in the refractive index occurring at the surface of the gold film. In this
presentation the underlying theory of the sensor device will be explained with a
discussion of a novel multi-analyte parallel sensor arrangement that is currently
under development by the nanotechnology research group.
To achieve a parallel array of sub wavelength apertures a method employing
colloidal nanolithography is under development. Preliminary results from this
process will be presented and options for the future development of this technique
will be discussed.

Investigation of organic photovoltaic cells with Scanning Probe Microscopy Department of Engineering Technology
Abstract:
Photovoltaic cells are solar cells that convert light energy into electric energy. In
organic photovoltaics, polymers, organic molecules or a combination of both are used
as the photoactive material, which absorb light to provide a photo-voltage and photo-
current to a connected consumer device. Due to simpler and cheaper production
methods, polymer based photovoltaic cells offer an attractive alternative to silicon
based cells, which currently dominate the photovoltaic market. For an operating
photovoltaic cell, the energy production cost (€/kWh) relates to both its efficiency and
lifetime. A successful deployment of organic photovoltaic cells requires substantive
improvements in both key factors.
The cell efficiency depends on 1) the probability of light absorption, 2) the yield of
free charge carrier generation from the absorbed light and 3) the likeliness of these
charge carriers to reach the electrode contacts of the cell, so that charge carriers can
contribute to the photo-current of the cell. Chemical and physical changes taking
place within the cell lead to a degradation of the cell efficiency and are responsible
for finite cell lifetimes [1].
The generation of charge carriers depends on the local electronic properties of the
cell materials and the interface morphology between cell components, which can
both vary at the nanoscale. The charge transport properties and effects of
degradation processes can also vary at such scale. Therefore, the access to cell
properties at the nanoscale can provide valuable, additional information for the
optimisation of organic photovoltaic cells besides the observations obtainable from
macroscale measurements. Scanning probe microscopy related techniques based on
scanning tunnelling microscopy (STM) and scanning force microscopy (SFM) allow
the nanoscale investigation of organic photovoltaic cell structures [2,3].
A customised STM, developed in-house, was used for the imaging of cell interfaces at
nanoscale resolution and the nanoscale recording of I-V spectroscopy and z-V
spectroscopy of organic photovoltaic cell structures. The spectroscopy methods
allowed the extraction of local electronic and opto-electronic properties of the
investigated samples. STM, SFM and UV-Vis spectroscopy have been applied to
study the degradation effects of oxygen on polymer based photovoltaic cells.

Reconfigurable Adaptive Wireless Sensor Node Department of Engineering Technology
Email: [email protected]
Abstract:
The wireless sensor network (WSN) is a new class of network that has appeared in
the last few years. A wireless sensor network is essentially a network of spatially
distributed individual devices referred to as nodes which have the ability to sense
and/or control their environment. In the modern fast paced world in which we live,
WSNs are increasingly employed in a wide range of applications, such as home
automation, smart buildings, environmental monitoring, energy monitoring, health
monitoring, industrial process control, natural disaster detection, etc.
While WSNs are already shown to be capable of supporting and facilitating many
applications, they continue to represent a diverse and challenging research area.
Because of the large variety of sensors, a significant challenge in many applications
is how to support or integrate different types of sensors within each node of the
network to realise the specific goals of the system.
The reconfigurable adaptive wireless sensors (RAWS) research programme proposes
that a solution to this is to devise a sensor node technology that can reconfigure
itself to accommodate different sensors. This can be achieved by leveraging the self-
identification feature of recent smart sensor standards. The research will investigate
the feasibility of developing a highly capable sensor node technology with
reconfigurability, multiple sensing capabilities, and wide applicability for
deployment in low power high utility wireless sensor networks.

FCA on SNA – Social Network Analysis Telecommunications Software & Systems Group
Email: [email protected]
Abstract:
Social behavior data are generated by people interacting with each other and with
services every minute of every day and accumulated into large volumes. Recent
studies have shown that the underlying networks from these datasets are complex,
however they can contain rich information which can be exploited in many
applications. Social network analysis (SNA) has attracted great attention from
networking area and data mining area where it was previously the reserve of
sociologists. Given networks with well defined relationships, networking paradigms
provide efficient mechanisms to effective walk through the networks. However,
typically social network data are not limited in the form of linked data, individuals
can be mediately connected by the events they involved or features they hold. Ming
these two mode social data composing of both individuals and events or features
requires a sophisticated data mining approach.
Mining data of complex types has been investigated in data mining community for
decades, there are many potential approaches that can be applied. Formal concept
analysis (FCA) has been reported to be a good method to extract the hidden
relations, cliques and communities from social datasets. Particularly for those two
mode social network, FCA can effectively catch the relations between persons,
relations between events and also the relations between persons and events, and
structures these relations into a Galois Lattice (a network-like mathematic
diagram). While the main issue that prevents the use of FCA across SNA
applications is due to its runtime complexity. A brute-force method that searches
every possible grouping of N objects leads to 2^n search space, which eventual
causes long term process when an input dataset is relatively large. Although many
advanced algorithms have been proposed, the runtime has not been reduced to a
satisfactory level for volume of data in most of the current databases. This research
investigates processing FCA on datasets with high dimensions and/or large scales,
where we propose a divide-and-conquer approach implemented by using a
distributed computing framework - hadoop, based on the theorems of Galois
connection. It aims to reduce the runtime of FCA process in order to enable the use
of FCA on nowadays social network data.

E-tandem Language Learning of Chinese and English: Some Challenges and
Recommendations Department of Languages, Tourism and Hospitality
Email: [email protected]
Abstract:
E-tandem language learning is an arrangement whereby two native speakers of
different languages communicate regularly at a distance using electronic media such
as e-mail, telephone and video conferencing with one another, each with the purpose
of learning the other‘s language. It is an underexploited but potentially a very
powerful use of computer-mediated communication in second language pedagogy
with the benefits of authentic, culturally grounded interaction. It is based on the
principles of bilingualism, reciprocity and autonomy.
The current research is an ongoing e-tandem project by e-mail between Irish
students studying Chinese as a foreign language in Ireland and Chinese students
studying English as a foreign language in China. In this project, the Irish students
are from the Ireland UCC Confucius Institute and the Chinese students are from
China Guangxi University of Technology, twelve students in each group. They
communicate on a one-to-one basis via e-mail exchanges. The languages exchanged
are Chinese and English. This project focuses on second language usage in a real
context and on increasing awareness of learners‘ own culture as well as the target
culture through interaction in e-tandem.
After a brief introduction of the background, the aim and the methodology of this
project, this poster will deal with the challenges associated with the development of
such a project. The challenges focus on recruiting appropriate participants,
establishing an online forum, designing effective task-based activities and carrying
out a pilot study of those tasks. Finally, some recommendations based on the
experience of establishing such an e-tandem project will be given. Overall this poster
presents the preliminary findings of this ongoing project which will make some
contributions to the current practice in e-tandem.
E-tandem will be significant in improving learners‘ L2 learning and intercultural
competence. This research will increase people‘s understanding and will provide
insights into the validity of e-communication as a language learning opportunity. It
will act as a gateway for real exchanges in distant languages experiences online by
adding new tandem language pairings-Chinese and English in Europe.

Development of hybrid SPM system using a quartz crystal tuning fork Department of Engineering Technology
Email: [email protected]
Abstract:
Scanning probe microscopy is the generic name for a family of instruments that
employ a nanosized probe to generate 3-D contour maps of the surface of a sample
under investigation. The resolution of these instruments can be sub atomic in the
case of scanning tunnelling microscopy (STM) and scanning force microscopy (SFM).
They can also provide atomic and molecular scale spectroscopic information relating
to the sample making them exceptionally powerful instruments for nanoscale
characterisation. The requirement of a conductive sample surface limits the use of
STM; however variations in conductivity across the sample surface can provide
information about the chemical state of the surface. While SFM is more versatile
with respect to the types of sample that can be characterised, electronic information
relating to the sample surface requires the use of a metal coated probe which may
limit the resolution of the instrument due to broadening of the probe by the coating.
In addition photoconductivity and electroluminescence measurements are
complicated in SFM due to the traditional laser/ cantilever beam bounce method of
force measurement. The lack of rigidity in the SFM probe makes the technique
unsuited to z-V spectroscopy – which is easily accessible through STM.
A growing area of research interest is the study of photoconductive organic polymers
and molecules that have applications in both illumination technology and solar
electricity generation. These chemicals are responsible for advances in display
technologies such as Organic Light Emitting Diode (OLED) televisions and plastic
solar technologies. The nanoscale morphology of these devices is considered to play
a vital role in optimising the device efficiency. Electroluminescence and
photoconductivity information that is directly related to the local morphology of the
organic electronic device will assist researchers in gaining a better understanding
the processes involved.
Quartz crystal tuning forks have been used in scanning probe microscopy as a
sensitive force detection technique; originally they were employed to guide a sharp
fibre optic probe towards a flat surface in scanning near field optical microscopy.
Their sensitivity to lateral forces allowed the probe to be positioned to within a few
nanometers of the surface under investigation. This sensitivity was later employed
to develop low cost scanning force microscopes that generated topography
information based on a measurement of the surface frictional force.

While these instruments did not have the high resolution of the scanned cantilever
type instrument, they did have the advantage of eliminating the laser beam from the
system. The elimination of the laser beam from the AFM offers many advantages for
SPM techniques such as nanoscale photoconductive imaging or nanoscale
electroluminescence image.
In this paper we will discuss the merits of our novel SPM design and the electronic
control system required for the generation of topographic maps of a sample surface.
Early stage results from this work will be presented along with a outline for future
work.
Keywords: Nanotechnology, SPM ,quartz crystal tuning fork.

A low-cost, precise beam direction controller for phased array antennas Department of Engineering Technology

Abstract:
There are currently two main challenges in mobile personal communications: first,
with the increase in mobile users, spectrum resources are declining and second, due
to poor channel quality, the desired signal will experience loss, fading and variable
delay before reaching the receiver antenna. These two issues (declining resources in
the face of increasing demand) are the principal, contradictory challenges in the
development of mobile communication technology.
An effective means of simultaneously addressing both of these issues is to use smart
antennas, where the term smart refers to an ability to spatially select transmission
or reception angles of interest.
Currently, research on smart antenna technology has not yet reached the practical
stage, partly because of the complicated environment of electromagnetic wave
propagation in mobile communications and partly due to the user‘s mobility. It is
often difficult for smart antenna adaptive process to both capture and track the user
signal dynamically. This problem is exacerbated by the discretisation of air-space in
conventional research, so that beams jump from discrete angle to discrete angle.
This work presents the design, implementation and validation of a hardware smart
antenna platform that dramatically and cheaply reduces the jumpiness of the
antenna beam. In effect this means that while the antenna beam angles dividing the
airspace into/from the antenna is still discrete, the level of granularity is so small
that moving from one antenna beam angle to the next appears as a smooth and easy
transition.
The frequency of operation is at 2.45 GHz form an Agilent vector signal generator
and the source signal is split four ways using a Wilkinson power splitter (designed
using Agilent‘s ADS software, easily extended to 8-, 12- or 16-element). In the mean
time the phase control (for ultimately defining the beam angle) is pre-calculated and
fed to a Digital-to-Analog Convertor (DAC) from a look-up table. The DAC (AD5308)
in turn feeds the two inputs of a Quadrature Modulator (AD8346), which is
simultaneously fed by one of the signals from the power splitter. The quadrature
modulator is able to control both phase and amplitude of the signal.

Two types of antenna are tested, PCB patch antennas and ceramic chip antennas.
Both antenna types were initially characterised in terms of antenna lobes, using the
Two Antenna Gain method, which measured both the main and side (or grating
lobes). Validation tests of the principle were performed in WIT‘s wireless anechoic
chamber, using a Tektronix DPX spectrum analyser.

Novel dielectric analysis of high permittivity powders and liquids Department of Engineering Technology
Email: [email protected]
Abstract:
Non destructive testing (NDT) is an important analysis technique to understand
material composition. Dielectric analysis is an NDT technique, using a probing
electromagnetic wave, which is both reflected and propagates through the material
under test (MUT). The MUT can be any insulating material, whose molecular
composition has a dipole moment that re-orientates in an applied electric field,
thereby classifying the insulating material as a dielectric. There are many such
dielectrics, the most common being water, with identifiable responses to probing
electromagnetic wavelengths at certain (material specific) frequencies. Over the past
three years test infrastructure has been developed here in WIT to probe MUTs over
a wide range of microwave frequencies (from 800MHz to 15GHz) and used to
characterise many materials, of differing shape, form (solids, liquids and powders)
and molecular composition. This work has been presented at the Royal Irish
Academy Radio Symposium and also at the European Wireless conference in Lucca,
Italy, both in 2010.
This work reports on the most recent infrastructure development, a glass tank, for
testing liquids and powders and also presents preliminary results. The materials
tested were common household cooking ingredients of salt, sugar, flour, as well as
tap water. Post processing of the measured parameters, using the free space upgrade
of the original Nicholson-Ross-Weir technique, yielded the MUT dielectric
properties. Some post processing difficulties arise, especially where the dielectric
properties are not known beforehand, meaning that the electrical length of the MUT
is unknown.
Finally, the next stage of infrastructure development is presented, to offer flexibility
and accuracy over a wider range of dielectric properties. The infrastructure is once
again a tank, albeit with the variation that it can now be varied in path width, so
that the MUT powder or liquid can be probed over varying microwave path widths.
This technique is novel and overcomes the difficulties of unknown dielectric
properties and, therefore, electrical length.

E-Commerce Development in China: a comparison between local and
foreign investment in China's e-commerce sector Department of Computing Mathematics and Physics
Email: [email protected]
Abstract:
My research topic is E-Commerce Development in China: a comparison between
local and foreign investment in China‘s e-commerce sector. The reason I choose this
topic is that the Chinese economic miracle has been regarded as a key factor
influencing the speed of world‘s recovery during current economic downturn. In this
circumstance, a great number of companies shift their focus to the growing Chinese
economy. Chinese online shopping market provides an enormous opportunity for
foreign e-commerce companies. In past decade the decreasing computer prices and
the increasing penetration of broadband services have led to dramatic growth of
internet population numbers in China. Until June 2009, according to China Internet
Network Information Center (CNNIC) report, the internet users in China has
reached 420 million, with an increase of 36 million compared to the end of 2009. The
popularity rate of internet has climbed to 31.8%, with an increase of 2.9% compared
to the end of 2009. In addition to this, according to iResearch (market analyst firm)
report, over 105 million of internet users now make regular purchases online. It is
also predicting that this number will double by 2011. In 2009, Chinese e-commerce
market totalled $38.5 billion with growth equivalent to about 105% increase year-on-
year. However, geographical diversity, cultural barrier and lack of understanding of
local customers‘ preferences make this market less accessible from outside world.
For instance, eBay acquired eachnet.com which had 79% market share in China‘s
customer to customer e-commerce market in 2003. At the same year, Taobao.com
was founded by parent Alibaba Group.
Today Taobao.com holds 83% customer to customer market share in China, compare
with Eachnet ebay which only holds 7% market share. The positions of two
companies are reversed. Why does this situation happen? The answer will be found
at the end of this research. At the same time, I wish the findings of this research will
serve as the guide book to those who are preparing to enter China‘s e-commerce
market.
Keywords: China's E-Commerce Market.
