We propose to study the particular context of a three-week summer camp in France that gathered teenagers from varied socioeconomic backgrounds. We argue that this camp provides a unique opportunity to observe the sociability of adolescents in well-bounded settings with equalized meeting opportunities, thus helping us to narrow down the specific role of <em>homophilic selection</em> - the process by which individuals actively select similar friends. We use Stochastic Actor-Oriented Models to analyze the declared friendships of participants. Furthermore, we introduce a novel longitudinal extension of the Exponential Random Partition Model (ERPM), a model developed for relational data organized in discrete groups, which we apply to observed meal-sharing among adolescents. Results point to weak to non-existent homophilic selection during the stay. In turn, this suggests that structural opportunities and contextual moderators might be essential in explaining the amount of socioeconomic homophily found at school or in other contexts.</p></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"74 ","pages":"Pages 259-274"},"PeriodicalIF":3.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49722667","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 basis of these models is the concept of an “event”, defined as a triplet of time, sender, and receiver of some social interaction. The key question that relational event models aim to answer is what drives the pattern of social interactions among actors. Researchers often consider a very large number of predictors in their studies (including exogenous effects, endogenous network effects, and interaction effects). However, employing an excessive number of effects may lead to overfitting and inflated Type-I error rates. Moreover, the fitted model can easily become overly complex and the implied social interaction behavior difficult to interpret. A potential solution to this problem is to apply Bayesian regularization using shrinkage priors to recognize which effects are truly nonzero (the “wheat”) and which effects can be considered as (largely) irrelevant (the “chaff”). In this paper, we propose Bayesian regularization methods for relational event models using four different priors for both an actor and a dyad relational event model: a flat prior model with no shrinkage, a ridge estimator with a normal prior, a Bayesian lasso with a Laplace prior, and a horseshoe prior. We apply these regularization methods in three different empirical applications. The results reveal that Bayesian regularization can be used to separate the wheat from the chaff in models with a large number of effects by yielding considerably fewer significant effects, resulting in a more parsimonious description of the social interaction behavior between actors in dynamic social networks, without sacrificing predictive performance.</p></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"74 ","pages":"Pages 139-155"},"PeriodicalIF":3.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49762207","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}

While integrating schools seems an easy solution to enhance inter-group interaction, this is yet an empirical question as we know little about how networks structure along SES lines <em>in</em> school. We examine the tendency for friendship and parental networks in primary school to structure by SES. We furthermore explore the role of the local school context. To do so, we collected multiplex classroom network data among Dutch students in 68 classrooms (55 schools) in their final year of primary school (grade 6; age 11–12). We link these sociometric data to register data, and test our hypotheses using cross-sectional exponential random graph models and meta-analysis techniques. Findings show that the networks of primary school students and their parents display a tendency for same-SES over cross-SES ties, net of opportunity structures. We do not find evidence for SES differences in the strength of SES homophily. Descriptive analyses show SES disparities in the extent to which parents have ties with the parents of their children’s friends (i.e., intergenerational closure), but these disparities disappear when controlling for other tie-generating mechanisms using ERGMs.</p></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"74 ","pages":"Pages 127-138"},"PeriodicalIF":3.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49722767","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}
