一句话：混合方法实证发现社会资本促进男女开源长期参与，但专家构成单一的团队对女性不利。
开源项目的存续依赖贡献者持续参与，也能带来职业收益，但女性等群体更易退出。论文关注开源贡献者形成的社会网络如何影响长期参与，特别是男女差异。作者对 GitHub 项目进行大规模纵向生存分析，并结合用户调查的混合方法研究，考察社会资本（从社会连接中获得的资源）的作用。结果确认，社会资本对男女的长期参与都有利；然而在专业知识多样性不足的团队中，女性处于劣势，更可能退出。研究揭示社会网络与团队构成对开源参与公平性的影响，为促进包容和持续参与提供依据。
Sustained participation by contributors in opensource software is critical to the survival of open-source projects and can provide career advancement benefits to individual contributors. However, not all contributors reap the benefits of open-source participation fully, with prior work showing that women are particularly underrepresented and at higher risk of disengagement. While many barriers to participation in open-source have been documented in the literature, relatively little is known about how the social networks that open-source contributors form impact their chances of long-term engagement. In this paper we report on a mixed-methods empirical study of the role of social capital (i.e., the resources people can gain from their social connections) for sustained participation by women and men in open-source GitHub projects. After combining survival analysis on a large, longitudinal data set with insights derived from a user survey, we confirm that while social capital is beneficial for prolonged engagement for both genders, women are at disadvantage in teams lacking diversity in expertise.
