Most twin registries have not systematically collected the data required to determine gender identity, which has limited opportunities to evaluate potential familial contributors to gender diversity. This study addresses this gap by analyzing responses to gender identity questions introduced in Twins Research Australia’s 2023 survey. Among 4475 respondents (mean age 52.2 years, SD = 15.3), 36 (0.8%) indicated a transgender or gender diverse identity, which is consistent with population-based estimates of gender diversity internationally. Gender diversity co-occurred in 2/19 monozygotic pairs and 0/8 dizygotic pairs, giving rise to tetrachoric correlations of 0.62 (95% CI [0.33, 0.87]) and 0.00 (95% CI [0.00, 0.88]), respectively. These results broadly align with previous concordance estimates from twin studies that were specifically focused on gender identity. Although limited by a small sample size, these findings demonstrate the feasibility and utility of systematically collecting gender identity data through routine twin registry surveys.

Extant research examining the effects of top management team (TMT) gender diversity on firm performance report equivocal findings. We seek to enhance understanding of this critical relationship in the context of an acquisition, which necessitates changes in one or both firms during a process characterized by non-routine decisions, time pressures, high uncertainty, and frequent debates among strategic leaders. Specifically, we examine the effects of gender diversity of top management and female executives’ formal and informal power on post-deal performance. Our results indicate gender diversity has negative effects on post-deal performance. Further, in a subsample of acquirers with gender diverse teams, our results reveal that female executives’ structural power and ownership power have negative performance effects, while power conferred through an elite education has positive performance effects. Our findings highlight the need to expand gender diversity research to consider the strategic context facing diverse TMTs and power dynamics among them.

Ensuring a sustainable future by meeting the Sustainable Development Goals (SDGs) cannot be achieved without women's empowerment and gender equality. This study aims to determine whether there are differences between European banks in terms of their commitment to SDGs and the intensity of this commitment depending on their board gender diversity. A sample of the 50 largest European banks from 2016 to 2020 was used to perform hypothesis testing for differences in means. The results provide robust support for the assertion that banks with greater female representation on the board of directors have a greater commitment to the 2030 Agenda. The originality of this research lies in the use of indicators of commitment to SDGs corresponding to each of the five SDG pillars. This study thus provides the first evidence of the importance of distinguishing between these pillars when examining the relationship between commitment to SDGs and board gender diversity. This evidence advances the scant literature on this relationship.

Issues of sexual reproduction lie at the core of evolutionary thinking, which often places an emphasis on how individuals attempt to maximise the number of successful offspring that they can produce. At first sight, it may therefore appear that individuals who opt for gender-affirming medical interventions are acting in ways that are evolutionarily disadvantageous. However, there are persuasive hypotheses that might make sense of such choices in evolutionary terms and we explore these here. It is premature to claim knowledge of the extent to which evolutionary arguments can usefully be applied to issues of gender identity, although worth reflecting on the extent to which nature tends towards diversity in matters of sex and gender. The importance of acknowledging and respecting different views in this domain, as well as recognising both the uncertainty and likely multiplicity of causal pathways, has implications for clinicians. We make some suggestions about how clinicians might best respond when faced with requests from patients in this area.

This study analyzes the effects of gender diversity in management on organizational performance using Korea Workplace Panel Survey data for 2005, 2007, and 2009. Few studies have examined this relationship for firms outside the United States, particularly in Asian countries. Similar to previous research, our findings show that gender diversity in management has a U-shaped relationship with firm productivity. Second, the curvilinear relationship between gender diversity in management and firm productivity is stronger in service-oriented industries relative to manufacturing industries, with the highest level of employee productivity within homogeneous management groups. Third, we include a measure of workplace family-friendly policies to moderate the relationship between gender diversity in management and organizational performance. We find that the U-shaped pattern also holds in firms with a large number of family-friendly policies. This suggests that gender diversity in management has considerable influence on the productivity of Korean firms through interactions with family-friendly policies.

This study sought to investigate if there is a link between women on boards of directors and corporate sustainability. Using a sample of publicly listed firms from Australia, the results suggest some level of support that a link does exist. Boards that have a strong complement of gender diversity are expected to offer more effective monitoring of agents, as well as offer more stringent enforcement of ethical conduct, thereby minimizing affects of subversion of shareholder funds that can be detrimental to their returns. Accordingly, findings confirm a positive link between women on boards and economic growth. Because of their relational abilities, women on boards are more likely able to engage with multiple stakeholders and respond to their needs, resulting in an avenue for demonstrating social responsiveness, which is confirmed by the results. However, due to their backgrounds and work experiences, sex-based biases and stereotyping might exist in boardrooms with men directors discounting input from women directors on issues relating to environmental quality. The results of this study find that women directors are not significantly associated with environmental quality. Discussion is given to these findings along with paths for future research.
