“…23 Supporting this theory, empirical studies have found that highly productive researchers are those with the highest numbers of research collaborators. 24 Cross and colleagues (2004), however, found that colleague network size may function independently from scientific output such as published manuscripts and grants awarded. 25 Coauthor networks within an organization may be influenced by factors such as the number of coauthors per publication, faculty publishing repeatedly with the same coauthors or widely with a larger set of coauthors, and the proportion of coauthors within versus outside the organization.…”

BACKGROUND: Business literature has demonstrated the importance of networking and connections in career advancement. This is a little-studied area in academic medicine. OBJECTIVE: To examine predictors of intra-organizational connections, as measured by network reach (the number of first-and second-degree coauthors), and their association with probability of promotion and attrition. DESIGN: Prospective cohort study between 2008 and 2012. SETTING: Academic medical center. PARTICIPANTS: A total of 5787 Harvard Medical School (HMS) faculty with a rank of assistant professor or fulltime instructor as of January 1, 2008. MAIN MEASURES: Using negative binomial models, multivariable-adjusted predictors of continuous network reach were assessed according to rank. Poisson regression was used to compute relative risk (RR) and 95 % confidence intervals (CI) for the association between network reach (in four categories) and two outcomes: promotion or attrition. Models were adjusted for demographic, professional and productivity metrics. KEY RESULTS: Network reach was positively associated with number of first-, last-and middle-author publications and h-index. Among assistant professors, men and whites had greater network reach than women and underrepresented minorities (p<0.001). Compared to those in the lowest category of network reach in 2008, instructors in the highest category were three times as likely to have been promoted to assistant professor by 2012 (RR: 3.16, 95 % CI: 2.60, 3.86; p-trend <0.001) after adjustment for covariates. Network reach was positively associated with promotion from assistant to associate professor (RR: 1.82, 95 % CI: 1.32, 2.50; p-trend <0.001). Those in the highest category of network reach in 2008 were 17 % less likely to have left HMS by 2012 (RR: 0.83, 95 % CI 0.70, 0.98) compared to those in the lowest category.CONCLUSIONS: These results demonstrate that coauthor network metrics can provide useful information for understanding faculty advancement and retention in academic medicine. They can and should be investigated at other institutions.

“…For example, degree centrality is an important predictor of individual performance in virtual R&D teams [32] and contributes to the diffusion of Youtube videos [33]. The eigenvector centrality improve group performance and leader reputation [34], increase scholar productivity [35], and boost salesperson performance [36]. In the context of our study, degree and eigenvector centralities allow us better examine how the "status" or prominence of a node in the network can influence the success of campaigns.…”

“…Another recent study led by Abramo, D'Angelo, and Solazzi (2011) demonstrated the positive relationship between the degree of international collaboration and the quantity and quality of Italian university researchers. Notable studies reporting similar findings also include Persson, Glanzel, and Danell (2004), Barjak and Robinson (2007), He, Geng, and Campbell-Hunt (2009) and Abbasia, Altmannb, and Hossaina (2011).…”
