    Gender-based homophily in research: A large-scale study of man-woman collaboration Open PDF 
    (2021)

    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.

    The US scientific workforce is primarily composed of White men. Studies have demonstrated the systemic barriers preventing women and other minoritized populations from gaining entry to science; few, however, have taken an intersectional perspective and examined the consequences of these inequalities on scientific knowledge. We provide a large-scale bibliometric analysis of the relationship between intersectional identities, topics, and scientific impact. We find homophily between identities and topic, suggesting a relationship between diversity in the scientific workforce and expansion of the knowledge base. However, topic selection comes at a cost to minoritized individuals for whom we observe both between- and within-topic citation disadvantages. To enhance the robustness of science, research organizations should provide adequate resources to historically underfunded research areas while simultaneously providing access for minoritized individuals into high-prestige networks and topics.

    Gender differences in citation impact for 27 fields and six english-speaking countries 1996–2014 Open PDF 
    (2020)
    Thelwall, M.
    Initiatives addressing the lack of women in many academic fields, and the general lack of senior women, need to be informed about the causes of any gender differences that may affect career progression, including citation impact. Previous research about gender differences in journal article citation impact has found the direction of any difference to vary by country and field, but has usually avoided discussions of the magnitude and wider significance of any differences and has not been systematic in terms of fields and/or time. This study investigates differences in citation impact between male and female first-authored research for 27 broad fields and six large English-speaking countries (Australia, Canada, Ireland, New Zealand, the UK, and the USA) from 1996 to 2014. The results show an overall female first author citation advantage, although in most broad fields it is reversed in all countries for some years. International differences include Medicine having a female first author citation advantage for all years in Australia, but a male citation advantage for most years in Canada. There was no general trend for the gender difference to increase or decrease over time. The average effect size is small, however, and unlikely to have a substantial influence on overall gender differences in researcher careers. © 2020 Mike Thelwall.

    Who acknowledges who? A gender analysis

    Acknowledgements found in scholarly papers allow for credit attribution among non-authors—from individuals to organizations—that contributed to a piece of research. As such, they are associated with a different kind of recognition than authorship. While several studies have shown that social factors affect authorship and citation practices, few analyses have been performed on acknowledgements. Based on 878,250 acknowledgees mentioned in 291,167 papers published in 2015 retrieved from Web of Science, the objective of this work-in-progress is to better understand such credit attribution practices and how gender may influence them. Our results show that gender disparities generally found in authorship can be extended to acknowledgements, and that women are even more underrepresented in the acknowledgement than in the authors’ list of a paper. Our findings also confirm that women acknowledge proportionally more women. These results suggest that gender plays a role in the entire spectrum of credit attribution practices, from authorships to acknowledgements.

    Gender differences in performance of top cited scientists by field and country Open PDF

    In this descriptive study, we aim to show the potential gender differences in academic success, focusing on the top (i.e., most frequently cited) scientists by analyzing the work of more than 94,000 scientists in 21 fields across 43 countries. Our results indicate that female representation in the top tier of scientists strongly varies between countries (11.83%; s.d. = 0.046), with the highest proportion of top women scientists in Finland (20.45%) and the lowest in Saudi Arabia (2.08%). Compared with the total share of females in science, women are underrepresented among the top (i.e., most frequently cited) scholars by 28.52 percentage points. The proportions differ by disciplines, with top women authors best represented in Public Health and Services (36.1%), Communication and Textual Studies (33.7%), Psychology and Cognitive Science (27.5%), and Social Sciences (23%); while the lowest share of women scientists are found in Mathematics and Statistics (6.3%), Engineering (7.2%), and Physics and Astronomy (7.7%). However, despite the low female representation, top women scholars in those three fields conduct (on average) more impactful research than their male colleagues, which is contrary to most other research fields. We also show that female scientific success is positively correlated with a nation’s higher gender equity indicators, lower discriminatory values, and less negative attitudes and preferences towards women. Overall, our findings suggest that scientific fields are still struggling with gender inequality that pervades public life. © 2020, Akadémiai Kiadó, Budapest, Hungary.
