The meaning of closeness to women and/or LGBTQ+ physicists: a social network analysis

Authors: Chase Hatcher, Adrienne Traxler, Lily Donis, Camila Amaral, Justin Gutzwa, Charles Henderson, Ramón Barthelemy

Abstract: 'Closeness' is well-defined as a quantitative measure of centrality in social network analysis (SNA), but it is not as well defined qualitatively as a description of social relationships. This paper presents a qualitative analysis of 'closeness' as it is defined both implicitly and explicitly in interviews with 100 women and/or LGBTQ+ PhD physicists.

This paper presents a qualitative analysis of 'closeness' as it is defined both implicitly and explicitly in interviews with 100 women and/or LGBTQ+ PhD physicists. The interviews include a social network construction component, and we define a quantitative network parameter that serves as a proxy for closeness, which we examine in relation to attributes of network members. We find that physicists in this sample see trust, relaxed boundaries, reliance, and support as concepts that most directly define closeness in their relationships. Consistent interaction, positive affect, and commonalities are also often present in (and in some cases, defining of) these relationships. From the quantitative analysis, we find that these physicists tend to view family and partners, friends, and professional friends as comprising their closest relationships. These results are consistent with other studies which have sought to define closeness qualitatively, but the prevalence of trust in this dataset in particular suggests that these physicists see the ability to confide as uniquely important in their relationships. We make recommendations to institutions supporting and employing physicists on how to better support gender and sexual minority (GSM) physicists going forward, and we believe these results help us gain a better understanding of how GSM physicists find success in physics despite the barriers they face due to their identities. △ Less

Unique support from identity-based groups: Professional networks of women and LGBTQ+ physicists analyzed and compared by career sector

Authors: Chase Hatcher, Adrienne Traxler, Lily Donis, Madison Swirtz, Camila Manni, Justin Gutzwa, Charles Henderson, Ramón Barthelemy

Abstract: This paper presents a social network analysis of the professional support networks of 100 LGBTQ+ and/or women PhD physicists, comparing the networks based on the career sectors of academia, industry, and government/nonprofit. The methods for constructing and analyzing the ego networks, which are novel in many ways, are explained in greater detail in an earlier publication (Hatcher et. al., 2025).… ▽ More This paper presents a social network analysis of the professional support networks of 100 LGBTQ+ and/or women PhD physicists, comparing the networks based on the career sectors of academia, industry, and government/nonprofit. The methods for constructing and analyzing the ego networks, which are novel in many ways, are explained in greater detail in an earlier publication (Hatcher et. al., 2025). We describe the networks of the whole group and use statistical tests of independence to explore differences between sectors in terms of whole network metrics, network composition based on alter (network member) characteristics, and support. We find that alters associated with groups (like affinity groups and personal and professional interest groups) are more likely to provide identity-based and community building support, participants in Academia have fewer personal friends in their networks while those in Industry have more, participants in Government report less instrumental support, and those in Academia report less material support. These results and others lead to suggestions for employers in these sectors on how to better support these physicists, including continuing to promote participation in affinity and interest groups, providing more material support and/or personal time in the academic sector, and more instrumental support in the form of professional development or training in the government sector. △ Less

Egocentric Mixed-Methods SNA: Analyzing Interviews with Women and/or LGBTQ+ Ph.D. Physicists

Authors: Chase Hatcher, Lily Donis, Adrienne Traxler, Madison Swirtz, Camila Manni, Justin Gutzwa, Charles Henderson, Ramón Barthelemy

Abstract: Social network analysis (SNA) has been widely used in physics education research (PER) in recent years, but mostly in a limited range of the available modalities. This paper describes a unique approach to egocentric, mixed-methods SNA applied to qualitative network data obtained from 100 interviews with women and/or queer professional physicists.

This paper describes a unique approach to egocentric, mixed-methods SNA applied to qualitative network data obtained from 100 interviews with women and/or queer professional physicists. We focus on our methods for obtaining quantitative network data from these qualitative sources and present novel techniques for analysis of the networks. We also examine the ways in which egocentric and mixed-methods SNA techniques are aligned with critical methods and well-suited to the study of difference, non-normativity, and experiences of marginalization in physics spaces and communities. We explore the limitations and potential applications of these methods and situate this work in the larger context of our study of these interviews. This work bridges a methodological gap between SNA and qualitative work on identity in PER and begins to develop our understanding of the way gender and sexual minority physicists experience support. △ Less
