Summary: This study examines the homophily of Corporate Social Responsibility (CSR) practices among listed firms in the Mexican Stock Exchange. The results show that board interlocks and industry affiliation are important mechanisms influencing CSR certification homophily, and that mimetic, normative, and coercive institutional forces have different effects on CSR adoption.

Summary: Homophily is the tendency for individuals with similar characteristics to connect with each other in social networks. This study examines the impact of homophily on information diffusion dynamics through theoretical analysis and numerical simulations. The results show that homophily significantly affects the dynamics of information diffusion. It facilitates local diffusion and inhibits global diffusion, especially in networks with strongly separated communities.

Summary: This study examines the developmental change in the similarity between friends and nonfriends during adolescence. The results show that the correlation between friends increases with age for most attributes, and school size and attribute variability partially mediate this developmental change.

Summary: This study explores whether homophily extends to brain structure. By analyzing friendship network data and neuroanatomic imaging data of children, the study found that mutual friends have more similar social brain networks.

Summary: This article studies the spread of misinformation in a social network with unequal access to learning resources. The study shows that inequality plays a significant role in the spread of misinformation, and the relationship between the prevalence of misinformation and inequality is nonmonotonic.

Summary: Contagion across various types of connections is a central process in studying political phenomena, and there has been a significant increase in methodological literature on causally identifying contagion in networks. Shalizi and Thomas propose a permutation test for contagion in longitudinal network data that addresses the challenge of confounding factors such as homophily. Through simulation, they demonstrate the properties and statistical power of this test under different conditions. Applying the test to the international spread of democracy, they find evidence of international contagion and discuss its practical applicability in studying contagion in political networks.

Summary: This study develops and estimates a structural model of network formation with heterogeneous players and latent community structure, successfully replicating homophily and clustering levels observed in real-world social networks. It explores community-specific payoffs and racial homophily across communities.

Summary: Observation of 'similarity breeds connections' principle in different types of networks gives rise to homophilic networks, where nodes of the same class preferentially interact with each other. This study introduces HONTO, an open-source Python3 package that evaluates and analyzes homophily in complex networks. The tool takes network and node partition as input and produces a matrix of homophily/heterophily z-score values. Additionally, it provides z-score values for nodes that do not interact with any other node of the same class, presented as a heatmap for easy interpretation.

Summary: Social influence is difficult to identify from observational data due to confounding with latent homophily. However, using network models, we can estimate the hidden homophilous attributes and consistently estimate the social influence effects.

Summary: This study examines the influence of social media and information-sharing behavior on young adults' perceptions of changes in tie strength within their personal networks. The results show that social media leads to a closer connection between young adults and friends who exhibit similar online behaviors, mainly driven by frequent interactions and the sharing of similar political and entertaining content.

Summary: This study examines the impact of social media on private donations for natural disaster relief efforts from households. It finds that both ethnic factors and political figures' statements on social media play significant roles in shaping the patterns of private transfers.

Summary: This study uses data on research collaboration at the University of Sao Paulo from 2000 to 2019 to explore the structure of a network with high academic endogamy, investigate if academic collaborations are more common among individuals with shared endogamy status, and analyze whether tie formation differs between inbred and non-inbred scholars. The results indicate a growth in collaborations over time, but ties are more likely to form when both inbred and non-inbred scholars share endogamy status. Furthermore, the homophily effect appears to have a greater influence on non-inbred scholars, suggesting that the institution may be missing out on opportunities to access unique information from its own faculty members.

Summary: This study extends previous research on adolescent friendship networks by examining the effects of status differential and homophily, comparing friendship patterns between China and the U.S., and identifying commonalities and differences in friendship formation processes. The results show uneven distribution of friendship ties by individual characteristics, significant tie homophily among high status subjects, and the presence of endogenous tie formation processes such as reciprocity and transitivity.

Summary: This paper analyzes the gender difference in citations in physics and claims that timing is one of the main factors driving this difference. The study finds that women's papers have lower visibility in the global citation network, which is significantly influenced by the temporal aspects of scientific production. Additionally, authors who publish first tend to obtain more citations, and men have cumulative historical advantages due to women joining the field later and at a slower rate. Overall, the first-mover advantage plays a crucial role in the emergence of gender disparities in citations of women-authored papers in the physics community.

Summary: Improving the position of minority groups in networks through interventions is a challenge that requires systematic analysis. In this study, we propose a model to examine the impact of network growth interventions on the position of minority nodes. We find that coordinated interventions are necessary to increase minority representation in rankings.

Summary: Temporal networks of face-to-face interactions provide insights into the dynamics of social systems. We propose a framework that combines observed interaction networks with underlying social bond networks, taking into account mechanisms such as triadic closure and shared social context. We compare different versions of the model with empirical data to understand the mechanisms that lead to realistic social temporal networks.
