    Do females create higher impact research? Scopus citations and Mendeley readers for articles from five countries Open PDF 
    (2018)
    Thelwall, M.
    There are known gender imbalances in participation in scientific fields, from female dominance of nursing to male dominance of mathematics. It is not clear whether there is also a citation imbalance, with some claiming that male-authored research tends to be more cited. No previous study has assessed gender differences in the readers of academic research on a large scale, however. In response, this article assesses whether there are gender differences in the average citations and/or Mendeley readers of academic publications. Field normalised logged Scopus citations and Mendeley readers from mid-2018 for articles published in 2014 were investigated for articles with first authors from India, Spain, Turkey, the UK and the USA in up to 251 fields with at least 50 male and female authors. Although female-authored research is less cited in Turkey (-4.0%) and India (-3.6%), it is marginally more cited in Spain (0.4%), the UK (0.4%), and the USA (0.2%). Female-authored research has fewer Mendeley readers in India (-1.1%) but more in Spain (1.4%), Turkey (1.1%), the UK (2.7%) and the USA (3.0%). Thus, whilst there may be little practical gender difference in citation impact in countries with mature science systems, the higher female readership impact suggests a wider audience for female-authored research. The results also show that the conclusions from a gender analysis depend on the field normalisation method. A theoretically informed decision must therefore be made about which normalisation to use. The results also suggest that arithmetic mean-based field normalisation is favourable to males. © 2018 Elsevier Ltd. All rights reserved.

    INTRODUCTION: Given the need to increase female representation in hepatopancreatobiliary (HPB) surgery, as well as the need to increase the academic pipeline of women in this subspecialty, we sought to characterize the prevalence of female authorship in the HPB literature. In particular, the objective of the current study was to determine the proportion of women who published HPB research articles as first, second, or last author over the last decade. METHODS: All articles pertaining to hepatopancreaticobiliary (HPB) surgery appearing in seven surgical journals (Annals of Surgery, British Journal of Surgery, JAMA Surgery, Annals of Surgical Oncology, HPB (Oxford), Surgery, and Journal of Gastrointestinal Surgery) were reviewed for the years 2008 and 2018. Information on sex of author, country of author's institution, and article type was collected and entered into a computerized database. RESULTS: Among the 1473 index articles included in the final analytic cohort, 414 (28%) publications had a woman as the first or last author, while the vast majority (n = 1,059, 72%) had a man as the first or last author. The number of female first authors increased from 15.6% (n = 92/591) in 2008 to 25.7% (n = 227/882) in 2018 (p < 0.001). There were no differences in the proportion of second (n = 123/536, 23.0% vs n = 214/869, 24.6%, p = 0.47) or last (n = 44/564, 7.8% vs n = 88/875, 10.1%, p = 0.15) authors. Women were more likely to publish papers appearing in medium-impact journals (OR 1.40, 95% CI 1.04-1.88) and articles with a female author were more likely to be from a North American institution (referent: North America, Asia OR 0.43, 95% CI 0.31-0.59 vs Europe OR 0.67, 95% CI 0.51-0.87). CONCLUSION: Women first/last authors in HPB research articles have increased over the past 10 years from 22 to 32%. Women as last authors remain low, however, as only 1 in 10 papers had a senior woman author. These data should prompt HPB leaders to find solutions to the gap in female authorship including mentorship of young female researchers and surgeons.

    We analyzed 2898 scientific papers published between 1995 and 2017 in which two or more authors shared the first author position. For papers in which the first and second authors made equal contributions, mixed-gender combinations were most frequent, followed by male-male and then female-female author combinations. For mixed-gender combinations, more male authors were in the first position, although the disparity decreased over time. For papers in which three or more authors made equal contributions, there were more male authors than female authors in the first position and more all-male than all-female author combinations. The gender inequalities observed among authors who made equal contributions are not consistent with random or alphabetical ordering of authors. These results raise concerns about female authors not receiving proper credit for publications and suggest a need for journals to request clarity on the method used to decide author order among those who contributed equally.
