Research impact and scholars’ geographical diversity

See on Scoop.itDual impact of research; towards the impactelligent university


In recent years there has been a sharp increase in collaborations among scholars and there are studies on the effects of scientific collaboration on scholars’ performance. This study examines the hypothesis that geographically diverse scientific collaboration is associated with research impact. Here, the approach is differentiated from other studies by: (a) focusing on publications rather than researchers or institutes; (b) considering the geographical diversity of authors of each publication; (c) considering the average number of citations a publication receives per year (time-based normalization of citations) as a surrogate for its impact; and (d) not focusing on a specific country (developed or developing) or region. Analysis of the collected bibliometric data shows that a publication impact is significantly and positively associated with all related geographical collaboration indicators. But publication impact has a stronger association with the numbers of external collaborations at department and institution levels (inter-departmental and inter-institutional collaborations) compared to internal collaborations. Conversely, national collaboration correlates better with impact than international collaboration.



The authors:”The fact that international collaboration has a lower correlation to publications’ impact may bedue to the apparent challenge of collaboration across national and cultural boundaries. The reason for intra-departmentalcollaboration’s low correlation to publications’ impact may be explained by exchanging redundant knowledge among theresearchers in the same departments (as usually have access to similar kinds of resources and equipment).Therefore, the findings support that having co-authors with diverse knowledge and skills enhance scholars’ knowledgeand experience through decreasing the research project process, including writing and revision process of publication (asthe output of the work) and also improving the impact.”
