Main Path Analysis
• “a single main path contains the key intellectual developments in the field and work by the acclaimed founders appears on the main path”
• Prior main path work by authors – DNA theory (Hummon and Doreian 1990)– Measures of centrality in social network research
(Hummon, Doreian, and Freeman 1990)

Case Study: Conflict Resolution
• Perform Main Path Analysis on emergence and eventual dissolution of discipline of Conflict Resolution
• Studied authorship and citations of the flagship publication – Journal of Conflict Resolution
• Analyzed in context of previous historical analysis of same subject (Harty and Modell 1991)
Case Study: Conflict Resolution
• Emerged in late 50s• Intended to be interdisciplinary effort• Formal publication only lasted 15 years (1957 –
1971)• Research efforts split back into separate disciplines
or splintered off• Historical analysis provided context to dissolution • Authors wanted to examine the literary structure of
this development of conflict resolution in JCR• Hypothesized the main path technique would fail to
find a main path of conflict resolution development
Case Study: Journal of Conflict Resolution
• Examine the authors and citations of the 15 volumes of the Journal of Conflict Resolution
• Identify authors who had both authored and had been cited
• Map the connections to follow how ideas emerged and further developed
• Review the historical analysis to provide additional context to findings

Interpretation
• The Conflict Resolution movement remained multi-disciplinary, true interdisciplinary work was not occurring
• Authors tended to write one-off contributions and return to their main discipline
• Authors tended to stay clustered with other authors in the same domain with very little cross-discipline citations or co-authorship
Conclusion
• Main path diagrams map the intellectual influences and cross-fertilizations important to cumulative scientific progress
• Main path analysis combined with historical analysis, provides a richer, more detailed understanding of a historical period
• Historical analysis provides context of strong institutional influence
• Main path analysis can control for institutional influence and demonstrate the contributions of individuals
Discussion
• Given what we’ve seen thus far on the importance of cross-disciplinary integration, can it really be that hard? What actions do you think would make interdisciplinary research more likely to occur?
