Women are underrepresented in STEM (science, technology, engineering, and mathematics) careers, and this poses new challenges at the dawn of the era of digital transformation. The goal of the present study is to demonstrate how female role models influence girls’ preferences for STEM studies. This paper evaluates a role-model intervention in which female volunteers working in STEM go into schools to talk to girls about their careers. The study was conducted with 304 girls, from 12 years old (sixth primary grade) to 16 years old (fourth secondary grade), both before and after the role-model sessions. An adaptation of the expectancy–value theory of achievement motivation is used to test the extent to which this role-model intervention improves girls’ beliefs that they can be successful in STEM fields and increases their likelihood of choosing a STEM career. The results of multigroup structural equation modeling analysis show that on average, the role-model intervention has a positive and significant effect on mathematics enjoyment, importance attached to math, expectations of success in math, and girls’ aspirations in STEM, and a negative effect on gender stereotypes. Additionally, the female role-model sessions significantly increase the positive impact of expectations of success on STEM choices. Finally, the moderation role of the counterstereotypical content of the role-model sessions is tested. The results show that the higher the counterstereotypical character of the sessions, the higher the relationship between expectations of success in math and the choice of STEM. These results are discussed regarding their implications for long-term STEM engagement.

This study analyses the impact of political and regulatory pressures to increase the influence of women within the European board of directors’ network. To accomplish this, we used a longitudinal approach, tracking two centrality measures of a European directors’ network from 1999 to 2014. The network comprised publicly listed firms in 37 European countries, resulting in an extensive sample of 71,300 directors, of which around 10% were women. Governments promoting gender diversity in leadership positions have focused on two solutions: a slow track using voluntary approaches versus a fast track pushing for binding legislation. The panel data analysis shows how voluntary approaches to promote gender diversity, as implemented through corporate governance codes, have a positive and significant relationship with the ‘closeness’ of women to other directors in the network (i.e. their access to information). In contrast, binding legislation, such as gender quotas, increases women's role as unique ‘bridges’ between sub‐networks – a result that serves to heighten their ‘betweenness’ centrality (i.e. their control over information).
