A global perspective on social stratification in science
To study stratification among scientists, we reconstruct the career-long trajectories of 8.2 million scientists worldwide using 12 bibliometric measures of productivity, geographical mobility, collaboration, and research impact. While most previous studies examined these variables in isolation, we study their relationships using Multiple Correspondence and Cluster Analysis. We group authors according to their bibliometric performance and […] Lire la suite
Understanding super-partnerships in scientific collaboration: Evidence from the field of economics
Super-partnerships exist between scholars connected within densely-knit collaboration networks. Understanding how such relationships affect scholars’ careers is of great importance. In this paper, focusing on the longitudinal aspects of scientific collaboration, we analyze collaboration profiles from the egocentric perspective and use analytic extreme value thresholds to identify super-partners. A total of 5722 pairs of super-partners […] Lire la suite
Mettre en récit la circulation des documents savants sur Twitter: Étude de cas exploratoire sur l’article « Climate change impacts on bumblebees converge across continents » (Kerr et al., 2015)
Les récentes études sur l’évaluation de l’impact social et l’attention envers la recherche sur les médias sociaux montrent la nécessité de changer le focus sur la signification des métriques pour s’intéresser aux contextes de circulation de la recherche. Cette étude s’inscrit dans une démarche exploratoire afin de saisir l’apport de la mise en récit pour […] Lire la suite
Who games metrics and rankings? Institutional niches and journal impact factor inflation
Ratings and rankings are omnipresent and influential in contemporary society. Individuals and organizations strategically respond to incentives set by rating systems. We use academic publishing as a case study to examine organizational variation in responses to influential metrics. The Journal Impact Factor (JIF) is a prominent metric linked to the value of academic journals, as […] Lire la suite

Collection development in the era of big deals
Drawing on an original methodology using citations, downloads, and survey data, this paper analyses journal usage patterns across 28 Canadian universities. Results show that usage levels vary across disciplines, and that different academic platforms varied in their importance to different institutions, with for-profit platforms generally exhibiting lower usage. These results suggest economic inefficiencies exist in […] Lire la suite
