A widely used strategy is to establish social hubs within local neighbourhoods to promote social connection among residents, especially older adults. Yet little is known about the working and outcome of these social spaces, activities and programmes. The study seeks to address this knowledge gap and examine residents’ participation and membership in social activities and organisations within a public housing neighbourhood in Singapore using survey data (N = 300). Developing a comprehensive understanding of the social and spatial factors that facilitate resident interactions, Exponential Random Graph Models are employed, integrating three spatial mechanisms—spatial propinquity, spatial composition, and spatial configuration—alongside residents’ sociodemographic profiles, self-reported health and well-being, and perceptions of the local environment (e.g. place attachment, walkability). The study found that integrating multiple spatial mechanisms with residents’ characteristics offers deeper insight into local social connectedness. Spatial composition and configuration are stronger predictors of participation and membership than individual traits or proximity. It validates the configurational approach, showing that features like spatial integration and third places shape social interaction patterns. The findings illuminate how specific local organisations function as social hubs, offering guidance for designing community-based interventions while providing tools for evaluating such initiatives.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"85 ","pages":"Pages 121-133"},"PeriodicalIF":2.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145839933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a combination of network and IR-based insights, we aim to build a theory-driven, interpretable model of international sanctions that has high predictive utility. Using a separable version of dynamic network logistic regression, we test network theories of “Matthew effects”, reciprocity, and previous state-level sanctioning activity alongside traditional IR theories regarding the democratic peace, cultural or institutional similarity, power imbalance, and trade. Though we find that mechanisms from established IR theories largely hold with the inclusion of network endogeneity, endogenous network effects are more powerful than traditional IR concepts for predictive accuracy of the sanctioning network. We also find considerable differences for factors driving the imposition of sanctions (tie formation) versus persistence of sanction regimes (persistence), pointing to the importance of treating such effects separately.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"84 ","pages":"Pages 62-77"},"PeriodicalIF":2.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144922615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There continues to be debate about the pros and cons of eliciting a fixed number of alters for each respondent versus allowing the respondent to list as many or few alters as they would like. This article explores a random assignment of respondents to three treatment groups – (1) a fixed number of alters set at 30, (2) a variable number of alters up to 45, and (3) a variable number of alters up to 45 with a 20 alter minimum. The results indicate that, from a non-structural perspective, all levels of emotional proximity, interaction contexts, genders, and ages are consistently sampled across the three treatment groups. At the structural level, the behavior of individual metrics is also largely similar. However, the most significant differences arise in the collective behavior of structural metrics—specifically, in their correlation structure, the amount of redundant information each variable provides, and the diversity and interpretability of the observed structural variability. When a data collection strategy constrains network size, it reduces the sparsity of the correlation matrix, effectively decreasing the number of independent global variables needed to describe network structure and making these global variables less interpretable. In other words, networks constructed with a survey that limits size tend to be more similar to each other, exhibiting less structural diversity and yielding differences that are harder to interpret. However, we discuss how these differences may simply be mathematical artifacts, without necessarily implying a clear advantage in choosing one treatment over another. Finally, we argue that the field needs a targeted study to answer whether the differing numbers of alters listed is a function of network size.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"84 ","pages":"Pages 78-86"},"PeriodicalIF":2.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144932941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The popularity of NSUM has increased in recent years due to its ability to uphold privacy and cost-effectiveness. However, the NSUM is not exempt from biases resulting from participants’ behavior. In addition, the simpler and most popular NSUM estimators are based on averages, making them sensitive to deviations in the samples, which may cause significant errors. This work aims to study how robust procedures can overcome misreporting, contamination, and deviation due to conditions such as barrier effects, prevalence, skewness, and tail length. Specifically, the central objective of the article is to analyze the statistical robustness of NSUM methods, studying whether these methods are affected by outliers or unusual data. We employ eight robust proposals for each of the two classical NSUM estimators. We analyze robust estimators through simulation experiments using synthetic random networks such as Erdős–Rényi, Scale Free, and Stochastic Block Model structures to model different degree distributions and community structures with different prevalence levels in contaminated and uncontaminated scenarios. We compare the results of the simulations with real data on COVID-19 indicators in the United Kingdom and voting intention in the Spanish General Elections of 2023. This article shows that the classical NSUM estimators perform poorly in contaminated scenarios, while most of the robust proposals are not considerably affected. However, the performance of some robust NSUM estimators decreases under barrier effects. In addition, we observe that distortions created by small prevalence play an important role in selecting the most suitable robust NSUM estimator. Particularly, the robustification of the Mean of Ratios (<span><math><mi>MoR</mi></math></span>) estimator based on the Myriad operator typically exhibits the best performance (for MoR methods) across the various social network structures for different prevalence levels, reducing the estimation error regarding the non-robust methods by up to three orders of magnitude in contaminated scenarios.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"84 ","pages":"Pages 46-61"},"PeriodicalIF":2.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, previous network studies provide only snapshots, thus ignoring whether interreligious friendship-making changes throughout adolescence. A recent non-network study suggests increasing in-group friendships among Muslim girls and stability among Muslim boys, but it could not explain these differences and did not consider interdependence with non-Muslims’ friendship-making. To overcome these limitations, we study the trajectories of friendship-making among Muslim and non-Muslim boys and girls and assess the explanatory power of three key determinants of interreligious friendship-making dynamics: interreligious attitudes, religious norms that constrain out-group friendships, and reactions to friendship-making behavior of other groups. Addressing the methodological limitations of non-network research, we study friendship trajectories with stochastic actor-oriented models for network evolution applied to five waves of longitudinal friendship network data among 1122 Muslim and non-Muslim youth in German schools. We find that Muslim girls start out with at least as many interreligious friends as Muslim boys but that their tendency to have non-Muslim friends decreases substantially throughout adolescence. By contrast, the religious friendship-making of both Muslim boys and non-Muslims of either gender remains stable over time. We show that the increase in in-group friendships only applies to Muslim girls with high religiosity and that it is particularly strong for cross-gender friendships, suggesting that gendered religious norms can explain differences in the dynamics of Muslim boys’ and girls’ friendship-making. By contrast, interreligious attitudes and reactions to shifts in other groups’ friendship-making do not contribute to the observed friendship-making trajectories.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"84 ","pages":"Pages 110-122"},"PeriodicalIF":2.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145046129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two different social mechanisms are proposed to explain these interrelationships, suggesting relationships between gossip and informal social status in the opposite direction. First, the social bonding perspective suggests that gossip bonds between actors in a gossip triad shape their informal social status. Second, the social capital perspective indicates that employees’ informal social status leads to their position within gossip triads. The hypotheses are tested in a three-wave social network study among employees in a Dutch childcare organization. Results of stochastic actor-oriented models indicate a co-evolution between informal social status and the receiver’s role in a gossip triad, but not with the roles of sender and object. Contrary to what the social capital perspective predicts, employees’ informal social status negatively affects receiving gossip over time. In line with the social bonding perspective, receiving gossip positively affects informal social status over time. The co-evolution process suggests that over time, an equilibrium may emerge where an employee’s informal social status stabilizes at a point where enough gossip is received to sustain their social position. We conclude that the previously often neglected receivers of third-party information should be considered when examining the dynamics of workplace gossip.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"84 ","pages":"Pages 9-26"},"PeriodicalIF":2.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144813925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Community network intervention requires crisis managers to identify existing ties between response network members and to foster and develop relations to eliminate (or minimize) bottlenecks and bridge gaps in human service coverage. We argue that in early crisis intervention, when responders have an incomplete understanding of the situation and limited resources, crisis managers may employ LSNMs to model relationships between actors who share parallel objectives (such as shelter volunteers or substance use disorder treatment specialists) and roles (such as law enforcement and emergency medical responders). Doing so would allow managers to compare the impact of proposed courses of action based on limited existing data and to guide the development of subnetworks to implement intervention initiatives. To demonstrate the utility of LSNMs, we examine the crisis response network that emerged following Oregon Governor Tina Kotek’s January 2024 state of emergency declaration concerning the fentanyl abuse in Portland, the state’s largest city. We find that LSNMs can assist early emergency responders with limited initial network data to model networks and identify critical limitations, assess risks associated with intervention strategies, and prioritize network development efforts to address shortcomings within available resources.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"84 ","pages":"Pages 191-201"},"PeriodicalIF":2.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145415548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
