The action of ratifying an IEA is influenced by national level characteristics as well as agreement characteristics. However, these agreements can also be seen as being connected through the overlapping countries that ratify them, while countries can be seen as connected through the agreements they choose to co-ratify. The implicit bipartite structure of the IEA network, constituted by both countries and treaties, can give rise to two distinct, yet interacting one mode networks. Exploring the factors that influence each network can build on our understanding of IEA ratification in the present as well as the past, while expanding our understanding of agreement ratification generally. Moreover, the central sociological theories addressing IEA ratification have implications for how categories of countries co-ratify at different rates, both individually and together. The aim of this study is to explore how categories of both countries and agreements are associated with varying rates of co-ratification and how these associations have changed over time. Our analysis employs newly coded network data from over 840 multilateral IEAs between 208 countries, ranging in signing date from 1857 to 2022; using both period-based and lagged analyses, we consider the effects of past and ongoing mechanisms of treaty ratification. Our findings demonstrate only modest support for regionalism, while suggesting an evolution in the patterning of co-ratification, with a regime change from a world systems configuration to a world society one over the past 20 to 30 years. In addition to providing a picture of the evolving IEA system, this work demonstrates how the use of network methods in combination with a dual focus of countries and treaties can further our knowledge of various forms of agreement ratification.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"82 ","pages":"Pages 182-200"},"PeriodicalIF":2.9,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143864229","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}

One movement that combines local direct action with the goal of an international network of activists is Antifa. Single case studies have highlighted that local demonstrations and networks are still vital for antifascist groups. However, studies that examine the influence of spatial dynamics on building an international (digital) network beyond focusing on a single country are still lacking. This study, therefore, examines the impact of proximity on forming digital connections among 355 unique European antifascist groups. Using Exponential Random Graph Modeling (ERGM), we examine the hyperlink network across Europe via the groups’ online presence. The findings reveal that the languages of the groups and the geographical distance between them are significant predictors for the probability of displayed hyperlink connections. These results demonstrate the relevance of proximity theories in the field of digital activism.

We analyze the respondents’ ratings of occupations on three dimensions of cultural meaning—evaluation (good versus bad), potency (powerful versus powerless), and activity (lively versus quiet). We take deviations of respondents’ individual ratings from population evaluation, potency and activity estimates, focusing on deviations from consensus rather than consensus itself. Drawing on Breiger's (1974) work on duality, we examine two projections of the initial rectangular matrix of correlated deviations. Our two projections represent (1) the cultural communities that people form when they differ from consensus in similar ways, and (2) the clusters of occupations that move in similar ways across those subcultures. Correlations among the residuals at the person level are indicators of shared subcultural differences from the mainstream—different ways of meaning-making about what is valuable and worthy about occupational work. At the occupation level, the structure represents schemas for which occupations share common elements and move together when those elements are evaluated differently. We use dyad models to investigate what metrics of occupation similarity predict similarity in deviations from consensus. We find that similarity in affective meaning (evaluation, potency and activity), material requirements, rewards, and work characteristics all predict clustering at the occupation level. Demographic composition of occupations is less important. We find that older respondents, White respondents, and higher income respondents tend to discriminate more between occupations on evaluation and potency. Respondents who are more similar in age have more similar patterns of deviations. However, occupation-level variables are in general much stronger predictors of residual structure than respondent-level variables.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"82 ","pages":"Pages 153-165"},"PeriodicalIF":2.9,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844761","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}

Combining duality-based thinking with ecological diversity measures helps resolves some inherent ambiguities in the way that social scientists often think about diversity: the same relations that appear to increase diversity in some respects may, from a different perspective, decrease diversity.

While substantial strides have been made to address supply-side barriers to modern contraceptive (MC) adoption in these regions, demand-side obstacles like personal or partner opposition are less understood. This study investigates the role of social influence in shaping MC demand in communities with low modern Contraceptive Prevalence Rates (mCPR). Using the Structured Influence Process (SIP) framework, we examine how an individual's social relations and exposure to persuasive messages, either in support of or opposition to MC use, jointly influence their decision to adopt or reject contraceptives. Using survey data from two different Kenyan communities, both exhibiting low mCPR but one relatively higher than the other, we observe that mere exposure to MC users or non-users during free-time interactions is insufficient to sway usage decisions. However, the combination of direct contact with contraceptive users and persuasive messages emerges as a potent force of influence. In the lower mCPR community, only a few types of persuasive messages are circulated, and they are all consistently influential in either encouraging or discouraging MC use. These messages primarily appeal to individuals’ desire to do what is “right” by emphasizing social validation and deference to trusted authorities, or their desire to do what is “liked” by reinforcing interpersonal bonds and reciprocal obligations. In the higher mCPR community, a broader range of persuasive messages effectively promote MC use; however, only those invoking social shame effectively discourage it. These findings highlight a crucial distinction between “prevalent vs. persuasive” messaging: While many persuasive messages may be prevalent (i.e., used often), only a subset are also persuasive. Recognizing which messages are merely pervasive versus those that are genuinely effective is vital for efficiently allocating resources to promote or counter MC use narratives. Leveraging research across network science and persuasion, this study contributes to a more comprehensive understanding of how social influence shapes contraceptive decision-making.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"82 ","pages":"Pages 99-110"},"PeriodicalIF":2.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760987","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}

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.
