Community structure and patterns of scientific collaboration in Business and Management

摘要: This paper investigates the role of homophily and focus constraint in shaping collaborative scientific research. First, structures collaboration when scientists adhere to a norm exclusivity selecting similar partners at higher rate than dissimilar ones. Two dimensions on which similarity between can be assessed are their research specialties status positions. Second, shapes connections among depend opportunities for social contact. Constraint comes two forms, depending whether it originates institutional or geographic space. Institutional refers tendency select collaborators within rather across boundaries. Geographic is principle that, collaborations span different institutions, they more likely involve that geographically co-located dispersed. To study constraint, will argue favour an idea moves beyond formal co-authorship include also other forms informal intellectual exchange do not translate into publication joint work. A community-detection algorithm formalising this perspective proposed applied network submitted 2001 Research Assessment Exercise Business Management UK. While results only partially support research-based homophily, indicate use positions discriminating potential by from institutions with rating own. Strong provided constraints. Scientists tend forge intra-institutional collaborations; yet, seek outside own those who proximity. The implications analysis tie creation endeavours discussed.
