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).
International migration of researchers and gender imbalance in academia—the case of Norway Open PDF

Female representation among students and graduates in higher education is growing internationally. This is a promising trend for achieving gender balance in top positions in academia. But there is still a long way to go, as women accounted for 26 per cent in top positions at European higher education institutions in 2018. In this article, we examine the influence of international recruitment of researchers on the gender balance—or the lack of gender balance—in Norwegian academia. We draw on data from the Norwegian Register of Research personnel, linked with population statistics from Statistics Norway. These data show that 38 per cent of the researchers at Norwegian higher education institutions in 2018 were born abroad. The share of foreign full professors has increased from 16 per cent in 2001 to 27 per cent in 2018, while for postdocs there has been an increase from 31 to 69 per cent. In terms of overall gender composition, a higher percentage of the foreign-born researchers are male compared with the native Norwegians. The incidence of international recruitment differs significantly across academic fields and is particularly prevalent in engineering. This is also the field where the gender balance is most skewed generally. Taking these variables into account, we conclude that international migration is not among the factors contributing to the gender imbalance in Norwegian academia. In fact, international recruitment has contributed positively to the gender balance in Norway in the majority of the fields analysed. © 2022, The Author(s).
Publication rate expressed by age, gender and academic position - A large-scale analysis of Norwegian academic staff Open PDF
(2015)

This study investigates how scientific performance in terms of publication rate is influenced by the gender, age and academic position of the researchers. Previous studies have shown that these factors are important variables when analysing scientific productivity at the individual level. What is new with our approach is that we have been able to identify the relative importance of the different factors based on regression analyses (OLS) of each major academic field. The study, involving almost 12,400 Norwegian university researchers, shows that academic position is more important than age and gender. In the fields analysed, the regression model can explain 13.5-19 per cent of the variance in the publication output at the levels of individuals. This also means that most of the variance in publication rate is due to other factors. © 2015 The Authors.
Gender differences in research performance within and between countries: Italy vs Norway Open PDF

In this study, the scientific performance of Italian and Norwegian university professors is analysed using bibliometric indicators. The study is based on over 36,000 individuals and their publication output during the period 2011-2015. Applying a multidimensional indicator in which several aspects of the research performance are captured, we find large differences in the performance of men and women. These gender differences are evident across all analysed levels, such as country, field, and academic position. However, most of the gender differences can be explained by the tails of the distributions - in particular, there is a much higher proportion of men among the top 10 % performing scientists. For the remaining 90 % of the population, the gender differences are practically non-existent. The results of the two countries, which differ in terms of the societal role of women, are contrasting. Further, we discuss possible biases that are intrinsic in quantitative performance indicators, which might disfavour female researchers. © 2021 Elsevier Ltd.
