Understanding development patterns within these trade networks is crucial for promoting further growth. This study adopts a spatiotemporal perspective to analyze the dynamic evolution and driving factors of trade networks among BRI countries, utilizing the Separable Temporal Exponential Random Graph Model (STERGM) and a change point detection model. These methods assess the impact of endogenous structural variables, exogenous edge-level covariates, and exogenous nodal variables on the formation and dissolution of trade networks, as well as on stage-specific changes within these networks. The findings reveal that: (1) around 2017, the trade networks underwent a significant shift, with high-trade-value relationships growing faster than low-trade-value ones, and the networks have a small-world character. (2) China, Turkey, India, and Russia hold central positions in the trade networks, functioning as “bridges” and “hubs”; the prominence of Poland, the Czech Republic, and Ukraine has increased, while Thailand and United Arab Emirates have seen a relative decline; (3) geographical proximity, bilateral investment treaties, and shared legal origins foster trade network development, whereas exchange rate volatility and political distance have a negative impact. Countries with high urbanization, large populations, and strong economies are more likely to form trade relations. And these effects on the formation and maintenance of trade relations changed significantly before and after 2017. Therefore, while enhancing their own economic and social development, BRI countries should work to strengthen trade relations by bridging political differences and establishing trade agreements.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"82 ","pages":"Pages 80-98"},"PeriodicalIF":2.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760986","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}

Understanding the current information landscape is pressing given the current salience of false and misleading information. Given the growing prominence of podcasts within the information ecosystem, and the high levels of trust that podcasters enjoy from listeners, it is critical to better understand the role this medium plays in political communication. In this paper, we construct a bipartite network of podcasts and their invited guests. We then generate a network of paths that guests take as they move from one podcast to the next using entailment analysis, and evaluate if guests are typically invited to speak on less prominent shows first, before moving on to more prominent shows. This dynamic has several parallels to Centola’s power of the periphery hypothesis, complimented by the idea that guests may visit progressively more prominent podcasts as they themselves become more visible. We also find that shows aiming to feature a politically diverse set of guests on their own shows play an outsize role in brokering the movement of guests between liberal and conservative shows, although this cross-boundary brokerage has equivocal outcomes.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"82 ","pages":"Pages 65-79"},"PeriodicalIF":2.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714934","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}

Traditional models often overlook the fluidity of group composition, focusing instead on static memberships. In this paper, we introduce a comprehensive framework to empirically measure and analyze changes in group composition over time, offering new insights into group dynamics. We propose key metrics, including <em>Growth Rate</em>, <em>Churn</em>, and <em>Revitalization</em>, that quantify the movement of members in and out of groups. Further, we define distinct stages of group development, such as organic growth, dynamic growth, fluid stability, and erosion, which capture the evolving nature of group composition. A data-driven method is presented to systematically identify these stages across a group’s lifespan. As a case study, we apply our methodology to a dataset from the massively multiplayer online game Travian, involving nearly 900 alliances and over 17,000 players, revealing common patterns of group evolution and frequent transitions between growth and decline. Our findings underscore the value of understanding group stages, offering practical implications for managing dynamic groups in various organizational settings.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"82 ","pages":"Pages 39-54"},"PeriodicalIF":2.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143643732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, we know little about whether the rates and correlates of friendship instability change during the transition to young adulthood, even though this period is characterized by significant life events such as high school completion. Using new and unique network data from the PROSPER study, we address this gap by following the trajectories of roughly 2000 respondents’ close friendships from the start of high school to one year after graduation. Results suggest that friendship dissolution is frequent after high school, with only 35 % of friendships reported in respondents’ senior years of high school remaining intact one year later. Similar histories of substance use were more impactful in inspiring friendship persistence after high school than during adolescence, while the role of shared sociodemographic characteristics did not vary across developmental periods. After high school, young people were also more likely to maintain friendships with peers who previously reciprocated these relationships and reported friends in common. Our findings underscore how friendship dynamics change at the start of young adulthood in ways that carry implications for behavioral trajectories and life outcomes.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"82 ","pages":"Pages 27-38"},"PeriodicalIF":2.9,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
