    Women in STEM and STEM-related fields face many issues preventing their sustained inclusion and success, from as early as childhood. Many issues persist into adulthood and careers, including pay disparities, hostile workplace interactions, workload imbalances, and uneven expectations in domestic roles. A growing body of literature seeks to address and analyze female disparities by studying and publishing research related to societal and cultural issues faced by women in STEM. However, the gender of the authors of literature focusing on this type of research also matters as a woman's experience in STEM might provide a different context; equally, male allyship is imperative to furthering gains made in the field. To determine what proportion of authors publishing on female disparity in STEM fields are women, we employed a large-scale bibliometric study to examine the trends in the proportion of three metrics of female authorship on publications related to "Women in STEM" topics; specifically, we analyzed the total female authors, female first authors, and female last authors of 7240 published manuscripts. Literature published between 2000 and 2024 was accessed using a search engine with nine search terms related to issues facing women in STEM, including terms about gender parity, gender inequity, gender attrition, pay gaps, the leaky pipeline, student gender bias, and motherhood in STEM. Overall, the proportion of female authors in any position, including specifically as both first and last author, increased over the period of our study. Our results also indicate a sustained overrepresentation of female authors during the latter portions of our analysis. These results highlight an increase in female authorship on "Women in STEM" literature and demonstrate that female researchers are becoming more central in studying these topics. Although increasing female participation in subjects related to women in STEM is important for perspective, context, and solutions, male inclusion is also important to ensure buy-in in the workplace and allow an equal distribution of labor.

    Research in alkali-activated materials (AAMs) is an innovative and dynamic material science topic. This is due to the relevant performances in terms of physico-mechanical properties comparable to traditional construction materials (e.g., ordinary Portland cement). The sustainability of AAMs is often highlighted since they can be developed by using many natural or industrial by-products–based precursors. This leads to challenges with the optimization of AAM production due to their different performances, availability, and costs. However, they are flexible and locally adapted materials. The research interest in AAMs has rapidly increased in the early 2000s. In recent years, about 1,000 international articles have been published each year. This study aims at assessing the gender balance of this specific research topic to investigate the relevance of women’s participation. Author lists of the published articles were analyzed throughout the Scopus database, applying “alkali-activated material” and “geopolymers” as keywords in the titles, abstracts, and keywords search. The last 10 years (2009–2019) were taken into account. The gender of the most prolific authors was analyzed, and a focus of European authors on this topic was considered, as more than 25% of the research in AAMs have been carried out in Europe. The analysis of 5,900 publications in the last decade shows that there is currently a shift toward men in the gender balance in this specific research, and female authors only covered 22% of the most productive authors worldwide. Considering European authors, a more equal gender distribution is reached, when the first author is considered, with a concentration of women in the range of 36–56%, recorded over 1,396 articles. © Copyright © 2020 Masi, Manzi and Bignozzi.

    Publishing in peer-reviewed journals as a part of the doctoral education is common practice in many countries. The publication output of doctoral students is increasingly used in selection processes for funding and employment in their early careers. Against the backdrop of this development, the aim of this study is to examine (1) how performance during the doctoral education affect the probability of attaining research excellence in the early career; and (2) if there is performance differences between males and females in the early career and to which degree these gender differences can be explained by performance differences during the doctoral education. The data consist of Swedish doctoral students employed at the faculty of science and technology and the faculty of medicine at a Swedish university. Our main conclusions are that (1) research performance during the doctoral education has a positive effect on attaining excellence in the early career; (2) there is an interaction between publication volume and excellence during doctoral education suggesting that a combination of quantity and quality in doctoral students’ performance is indicative of future excellence; (3) there are performance differences in the early career indicating that males have a higher probability of attaining excellence than females, and; (4) this difference is partly explained by performance differences during the doctoral education. © 2019, The Author(s).

    The gender gap in science: How long until women are equally represented? Open PDF

    Women comprise a minority of the Science, Technology, Engineering, Mathematics, and Medicine (STEMM) workforce. Quantifying the gender gap may identify fields that will not reach parity without intervention, reveal underappreciated biases, and inform benchmarks for gender balance among conference speakers, editors, and hiring committees. Using the PubMed and arXiv databases, we estimated the gender of 36 million authors from >100 countries publishing in >6000 journals, covering most STEMM disciplines over the last 15 years, and made a web app allowing easy access to the data (https://lukeholman.github.io/genderGap/). Despite recent progress, the gender gap appears likely to persist for generations, particularly in surgery, computer science, physics, and maths. The gap is especially large in authorship positions associated with seniority, and prestigious journals have fewer women authors. Additionally, we estimate that men are invited by journals to submit papers at approximately double the rate of women. Wealthy countries, notably Japan, Germany, and Switzerland, had fewer women authors than poorer ones. We conclude that the STEMM gender gap will not close without further reforms in education, mentoring, and academic publishing.

    No evidence of citation bias as a determinant of STEM gender disparities in US biochemistry, genetics and molecular biology research Open PDF

    The lack of females in many Science Technology, Engineering and Mathematics (STEM) subjects in the USA is an ongoing concern, with many initiatives attempting to redress this imbalance. Some life sciences are apparently areas of relatively good practice, with higher proportions of female researchers than most other STEM subjects. This paper assesses gender differences in research contributions to 14 biochemistry, genetics or molecular biology specialisms in the USA 1996–2014/8, seeking evidence of trends in publishing and citation impact that may give insights into female success. With four exceptions (biochemistry, biophysics, biotechnology, and structural biology), the fields achieved or maintained at least 40% female first authors by 2018, with developmental biology and endocrinology both attaining female first author majorities. A regression analysis found close to gender parity overall in citation impact but a small male first author citation advantage in more fields than the opposite: an up to 3% increase in logged citation ratio to the world mean. This was partly due to males first authoring with larger teams. Fields with relatively many females did not favour female-led research with more citations, however. © 2019, Akadémiai Kiadó, Budapest, Hungary.

    Objectives Women in oral health science face similar societal issues and challenges as those in other STEMM careers, and gender disparities continue to exist as evidenced by fewer women represented as first and last authors in scientific publications. Pre-prints may serve as a conduit to immediately disseminating one's work, bypassing the arduous peer review process and its associated inherent biases. Therefore, the purpose of this study was to 1] compare the gender of first and last authors in pre-print versus peer reviewed publications, 2] examine the composition of first and last author pairs as stratified by publication type, and 3] examine the correlation between woman authorship and institutional geographic location and publication metrics stratified by publication type. Methods The keyword "oral health"was used to search for publications in BioRxiv and Pubmed in the years 2018 and 2019. Gender of first and last authors were determined, and its frequency was considered as the primary outcome. Additionally, the geographic location of the author's associated institution and publication metrics measured by Altmetrics score were extracted. Data was descriptively summarized by frequencies and percentages. Chi-square analysis was conducted for categorical variables which included the relationship between gender and publication type as well as gender and region of author's associated institution. Binomial regression analysis was conducted to analyze the relationship between gender and Altmetrics. Results Woman first authors comprised 40.3% of pre-prints and 64.5% of peer reviewed publications [p<0.05]. Woman last authors comprised 31.3% of pre-prints and 61.5% of peer reviewed publications [p<0.05]. When analyzing the relationships between first and last author, the Man-Man pairing represented 47.7% of the pre-print publications and the Woman-Woman pairing comprised a majority of the of the peer review publications at 47.5%. All results were statistically significant with a p-value <0.05. No significant correlation was found between region of institution or Altmetrics and gender of first or last authors [p>0.05]. Conclusion For the first time in oral health science, it was found that women show higher representation as first and last author positions in peer reviewed publications versus pre-prints. © 2021 Rajendran et al.

    How do public investments in gender equality initiatives and publication patterns interrelate? The case of Germany. Open PDF

    This article examines whether two of the major German flagship programmes to increase the participation of female researchers in the German science system, the "Women Professorship Programme" and the "Pact for Research and Innovation", have actually increased the number of women, especially in leadership positions. In a second step, we analyse whether such an assumed increase influences the publication patterns of authors with German affiliation. This article is based on literature and desk research as well as bibliometric analysis using Scopus. The most important result is that the number of women in research has indeed increased significantly in recent years and that, accordingly, more women are the (co)authors of scientific publications. In particular, it can be seen that quality indicators such as citations and excellence rates are high for female authors. This enables us to show that more women in the science system not only bring about a "gain in justice", but also a concrete scientific benefit.

    We examined the gender productivity gap in science, technology, engineering, mathematics, and other scientific fields (i.e., applied psychology, mathematical psychology), specifically among star performers. Study 1 included 3,853 researchers who published 3,161 articles in mathematics. Study 2 included 45,007 researchers who published 7,746 articles in genetics. Study 3 included 4,081 researchers who published 2,807 articles in applied psychology and 6,337 researchers who published 3,796 articles in mathematical psychology. Results showed that (a) the power law with exponential cutoff is the best-fitting distribution of research productivity across fields and gender groups and (b) there is a considerable gender productivity gap among stars in favor of men across fields. Specifically, the underrepresentation of women is more extreme as we consider more elite ranges of performance (i.e., top 10%, 5%, and 1% of performers). Conceptually, results suggest that individuals vary in research productivity predominantly because of the generative mechanism of incremental differentiation, which is the mechanism that produces power laws with exponential cutoffs. Also, results suggest that incremental differentiation occurs to a greater degree among men and certain forms of discrimination may disproportionately constrain women's output increments. Practically, results suggest that women may have to accumulate more scientific knowledge, resources, and social capital to achieve the same level of increase in total outputs as their male counterparts. Finally, we offer recommendations on interventions aimed at reducing constraints for incremental differentiation among women that could be useful for narrowing the gender productivity gap specifically among star performers.
