Item type:Publication, Identifying gender disparities in research performance: the importance of comparing apples with apples Open PDF(2022) ;Nygaard, L.P. ;Aksnes, D.W.Piro, F.N.Many studies on research productivity and performance suggest that men consistently outperform women. However, women and men are spread unevenly throughout the academy both horizontally (e.g., by scientific field) and vertically (e.g., by academic position), suggesting that aggregate numbers (comparing all men with all women) may reflect the different publication practices in different corners of the academy rather than gender per se. We use Norwegian bibliometric data to examine how the “what” (which publication practices are measured) and the “who” (how the population sample is disaggregated) matter in assessing apparent gender differences among academics in Norway. We investigate four clusters of indicators related to publication volume, publication type, authorship, and impact or quality (12 indicators in total) and explore how disaggregating the population by scientific field, institutional affiliation, academic position, and age changes the gender gaps that appear at the aggregate level. For most (but not all) indicators, we find that gender differences disappear or are strongly reduced after disaggregation. This suggests a composition effect, whereby apparent gender differences in productivity can to a considerable degree be ascribed to the composition of the group examined and the different publication practices common to specific groups. We argue that aggregate figures can exaggerate some gender disparities while obscuring others. Our study illustrates the situated nature of research productivity and the importance of comparing men and women within similar academic positions or scientific fields—of comparing apples with apples—when using bibliometric indicators to identify gender disparities in research productivity. © 2022, The Author(s).Item type:Publication, Gender-based homophily in research: A large-scale study of man-woman collaboration Open PDF(2021) ;Kwiek, M.Roszka, W.We examined the male-female collaboration practices of all internationally visible Polish university professors (N = 25,463) based on their Scopus-indexed publications from 2009-2018 (158,743 journal articles). We merged a national registry of 99,935 scientists (with full administrative and biographical data) with the Scopus publication database, using probabilistic and deterministic record linkage. Our unique biographical, administrative, publication, and citation database ("The Polish Science Observatory") included all professors with at least a doctoral degree employed in 85 research-involved universities. We determined what we term an "individual publication portfolio" for every professor, and we examined the respective impacts of biological age, academic position, academic discipline, average journal prestige, and type of institution on the same-sex collaboration ratio. The gender homophily principle (publishing predominantly with scientists of the same sex) was found to apply to male scientists - but not to females. The majority of male scientists collaborate solely with males; most female scientists, in contrast, do not collaborate with females at all. Across all age groups studied, all-female collaboration is marginal, while all-male collaboration is pervasive. Gender homophily in research-intensive institutions proved stronger for males than for females. Finally, we used a multi-dimensional fractional logit regression model to estimate the impact of gender and other individual-level and institutional-level independent variables on gender homophily in research collaboration. © 2021 EDP Sciences. All rights reserved.Item type:Publication, European Research Council: Excellence and leadership over time from a gender perspective Open PDF(2019) ;Bautista-Puig, N. ;García-Zorita, C.Mauleón, E.European Research Council Grants (ERC) have become the most important vehicle for funding scientific research in the EU. Since their creation in 2007, they have provided funding for around 7,000 of the nearly 70,000 proposals for research projects submitted. With a success rate of about 11%, these Grants are highly competitive. Despite major advancement of women's participation in research activity, women overall remain the minority in Science, Technology, Engineering and Mathematics (STEM disciplines). Against that backdrop, this article analyses men's and women's presence in ERC Grants. The gender balance in the ERC Grant, have been examined in three dimensions: Excellence Awarded; Scientific Leadership Position; and Time Series Evolution. The results show that female presence is lower than men as submitted (26% vs 74%), granted (22% vs 78%), expert panel members (28% vs 72%), and as a panel chair (26% vs 74%). State-space prediction of the future pattern of these grants shows that time has no clearly beneficial effect on women's participation as applicants, granted, expert panel members or panel chairs, particularly in the area of Physics and Engineering. © 2019 The Author(s).
