  1. Background The 2022 monkeypox (mpox) outbreak in Los Angeles County (LAC) emphasized the need to prepare for emergent infectious disease outbreaks. Vaccination and promotion of sexual risk reduction practices appeared successful in LAC, as mpox cases declined starting in August. Nonetheless, questions persisted regarding the effectiveness of targeting vaccinations and the role of sexual risk reduction in reducing mpox cases. Methods We collaborated with the LAC Department of Public Health to develop a microsimulation for men who have sex with men (MSM). This model tracked mpox dynamics by age, race/ethnicity, and HIV status and was calibrated and validated against surveillance data. We simulated counterfactual scenarios to understand the effects of variation in vaccination rates, timing of vaccination rollout, vaccine allocation, and sexual contact rates. Results In the simulation, doubling the vaccination rate reduced cumulative cases over a 40-week time horizon by 13% but would necessitate 88 995 additional doses. Initiating vaccination 2 weeks earlier decreased cases by 11%, while an 8-week delay yielded a 20% increase in cases. A 3-week earlier decrease in sexual contact rates reduced cumulative cases by 60%, while a 3-week delay resulted in a 95% increase. Prioritizing people with HIV (PWH) for vaccination reduced cumulative cases, while allocating vaccines to a single racial/ethnic group was not effective. Conclusions Our study highlights the significance of policies to support timely vaccination and sexual partnership reduction to address mpox outbreaks among MSM. These findings also underscore the need to target vulnerable risk groups, such as PWH.

  2. Men can make important contributions to gender equality, but a variety of obstacles impede their engagement with feminism. In this article, we propose a self-determination (Ryan & Deci, 2000) approach to supporting men’s feminist engagement. We argue that men are more likely to engage with feminism more consistently and effectively if they internalize feminist goals and incorporate them into their sense of self, that is, if they develop autonomous motivation. We argue further that men are more likely to develop autonomous motivation if their engagement with feminism satisfies basic psychological needs for autonomy, relatedness, and competence. We suggest a variety of strategies to meet these needs, among them: framing feminism as a men’s issue, considering men’s viewpoints and values, portraying feminism as consistent with gender and masculine norms, encouraging positive interactions with feminist women, and presenting other feminist men as role models and mentors. According to bell hooks (1984), “sexism and sexist oppression, they can only be successfully eradicated if men are compelled to assume responsibility for transforming their consciousness and the consciousness of society as a whole” (p. 81). Our article applies the self-determination theory (Ryan & Deci, 2000) to encourage men to do so. (PsycInfo Database Record (c) 2025 APA, all rights reserved)

  3. Abstract There is a well-documented gap between the observed number of works produced by women and by men in science, with clear consequences for the retention and promotion of women 1 . The gap might be a result of productivity differences 2–5 , or it might be owing to women’s contributions not being acknowledged 6,7 . Here we find that at least part of this gap is the result of unacknowledged contributions: women in research teams are significantly less likely than men to be credited with authorship. The findings are consistent across three very different sources of data. Analysis of the first source—large-scale administrative data on research teams, team scientific output and attribution of credit—show that women are significantly less likely to be named on a given article or patent produced by their team relative to their male peers. The gender gap in attribution is present across most scientific fields and almost all career stages. The second source—an extensive survey of authors—similarly shows that women’s scientific contributions are systematically less likely to be recognized. The third source—qualitative responses—suggests that the reason that women are less likely to be credited is because their work is often not known, is not appreciated or is ignored. At least some of the observed gender gap in scientific output may be owing not to differences in scientific contribution, but rather to differences in attribution.
