()End-user satisfaction increasingly represents thefocal point of successfully implementing an information system.Incapable of fulfilling user requirements independently,information systems require individuals to fully exploit theirexpertise before yielding organizational benefits. Factors

influencing user satisfaction with information systems havereceived considerable interest. Several studies have attributedinformation system failures to psychological and organizationalissues, rather than technological ones. Amongthe various theoretical perspectives adopted to explore thisphenomenon include the technology acceptance model, theory

of planned behavior, and information system success model.However, in contrast with previous findings, Au et al. (2008)found that expectations regarding information systemperformance are not significantly related to user satisfaction.Additionally, Iivari (2005) found that quality of the end userperceived information only slightly impacts system usage.

() Despite the considerable amount of scholarlyresearch on end-user satisfaction in recent decades, availableevidence contradicts the expected relationships. Still, the role of self-efficacy in the context of information system usage has seldom beenaddressed. Therefore, the role of self-efficacy in end-user satisfactionmodel warrants further study. According to social cognitive theory, end

user beliefs (referred to herein as self-efficacy) may influence theirbehavior and perceived outcomes. This study examines the role of self-efficacy in how end-user satisfaction, its antecedents, andconsequences are related. The inability toincrease end user satisfaction by elucidating the factors affecting theeffects of antecedents of user satisfaction and the consequences ofend-user satisfaction makes it extremely difficult for managers before,during, and after an information system is implemented. Therefore, the role of self-efficacy must be elucidated with respect tohow end-user satisfaction, its antecedents, and consequences arerelated.

() The role of self-efficacy can be elucidated with respect

to how end-user satisfaction, its antecedents, and consequences are

related. To do so, the perceptual data for this study

can be gathered via a self-administered questionnaire. Measurement

and structural models can then be estimated using Partial Least

Squares (PLS). Next, the measurement model in PLS can be evaluated

in terms of internal consistency, convergent validity, and discriminate

validity. Ultimately, validity of the structural model and hypotheses can

be (verified OR confirmed) by examining the path coefficients.

As anticipated, end-user self-efficacy significantly impacts how

end-user satisfaction, its antecedents, and consequences are related.While shedding light on end-user satisfaction research, results of this

study can significantly contributes to theoretical developments related

to end-user satisfaction by identifying the underlying factors that affect

end-user satisfaction, and their relative impacts.

() Our results can further demonstrate that low

self-efficacy, if not managed, lowers individual productivity.

Managers can thus motivate a high self-efficacy end-user

to be the mentor of low self-efficacy end user. Furthermore,

as a highly effective means of increasing self-efficacy,computer training can allow managers to increase end-user

self-efficacy by implementing training programs.

() Most metropolitan taxi services not onlycomplement public transportation, but also function as a vitalpart of urban travel. The Ministry of Transportation (MOT) of theRepublic of China cites individual taxis, cooperative associations,and taxi trades as the three business models in the Taiwan taxiindustry. Despite a recent focus on factors that

may influence whether passengers take a taxicab, exactly howthe taxi business model affects passenger behavioral intentionremains unclear. (NOTE : Add 3-4 more sentences thatdescribe characteristics of the problem or statistics that reflect itsseverity) According to MOT statistics, taxitrades in Taiwan rose from an annual rate of 42% in 2005 to

44% in 2007. Taiwan Taxi, a GPS-based taxi company, is amajor taxi trade in Taiwan has implemented a GPS-baseddispatching system from Singapore. In addition to benefiting thetaxi driver and taxi trade firms, GPS technology also providessense of security for passengers.

() The inability to understand how a specifictaxi business model impacts passenger behavioral intentionmakes it impossible to determine not only how a taxi businessmodel affects perceived safety, but also how perceived riskmediates the relation between the taxi business model and thebehavioral intention of passengers. These unresolved issues

make it extremely difficult for fleet line managers to draw upappropriate guide lines in order to comply with consumerpreferences. Therefore, exactly how taxibusiness models and the behavioral intention of passengers arerelated must be elucidated, as well as the mediatory effects ofpassengers perceived risk elaborated.


10/12

() Exactly how taxi business models and the behavioralintention of passengers are related can be elucidated, as well as themediatory effects of passengers perceived risk elaborated. To do so, a research design sample can be drawn from MBA,EMBA, and IEMBA students. Behavioral intention and perceived riskamong passengers can then be evaluated using existing scales. Next,

a factorial design can be implemented based on research dataaccumulated. Additionally, accumulated data can be analyzed using

ANOVA of the multivariate technique. As anticipated,analysis results can indicate that passengers tend to view a GPS-based taxi fleet the safest among other business models, becausepassengers perceive a GPS-based taxi fleet as most concerned withensuring their physical safety. As for managerial implications of thisstudy, among the variables that senior management can incorporate tofoster a sense of security among passengers include using thecorporate web site to promote the concern for safety and security,specifying the safety, service quality, and comfort in a taxicab, andtraining taxi drivers to convey the company's vision and mission to thepassengers.


11/12

() Importantly, this study can provide a valuablereference for managers concerned with a comprehensiveview of what risks are involved, as well as their likelyconsequences. (NOTE : Add 2-3 more sentences thatdescribe more thoroughly how the proposed method

contributes to a particular field or sector)
