Network Structure Explains the Impact of Attitudes on Voting Decisions

Attitudes can have a profound impact on socially relevant behaviours, such as voting. However, this effect is not uniform across situations or individuals, and it is at present difficult to predict whether attitudes will predict behaviour in any given circumstance. Using a network model, we demonstrate that (a) more strongly connected attitude networks have a stronger impact on behaviour, and (b) within any given attitude network, the most central attitude elements have the strongest impact. We test these hypotheses using data on voting and attitudes toward presidential candidates in the US presidential elections from 1980 to 2012. These analyses confirm that the predictive value of attitude networks depends almost entirely on their level of connectivity, with more central attitude elements having stronger impact. The impact of attitudes on voting behaviour can thus be reliably determined before elections take place by using network analyses.Comment: Final version published in Scientific Report

COHESION, INTEGRATION, AND ATTACHMENT IN OWYHEE COUNTY COMMUNITIES

How social change occurs is an important consideration when analyzing the effects of public land management policies on rural communities. This paper utilizes data from a recent study in Owyhee County, Idaho, to explore the combination of social attributes that contribute to community attitudes of cohesion, integration, and attachment in a set of rural communities. Specifically, we examine the importance of social networks and where a particular public land activity, ranching, fits into those networks. We then evaluate the role such networks play in determining respondent attitudes about the cohesiveness of their community, how they are integrated with people in their community, and how attached they are to where they live. The results indicate that increasing density of acquaintenship and intimate social connections to ranching and other local businesses increase the strength of cohesion and integration attitudes. Density of acquaintenship and intimate social connections to local businesses increase community attachment, but a social connection to ranching does not.Community/Rural/Urban Development, Land Economics/Use,

Group and intergroup parameters of gang activities: An introduction and research agenda.

In introducing this Special Issue on gangs, we overview the thrust of its papers, demonstrating how they assist in plugging research gaps from the dearth of psychological attention to gangs. The papers therein raise important theoretical considerations of group process effects, social identity, and communication influences in gangs. Also included are empirical examinations of how attitudes to formal organized crime groups may nurture progang views, how social networks bridge gang divides, the dehumanization and social dominance association with gang membership, and how membership longevity associates with gang members’ attitudes to their group. We conclude with theoretical prospects and empirical vistas for future work. For instance, vitality theory may help explain members’ immersion in gangs, discursive strategies could explain how youth are enticed into gangs, and examinations of community and law enforcement attitudes to gangs may provide insight into how oppositional attitudes are fostered on both sides of the gang divide

Impact of Perceived Peer Attitudes and Social Network Diversity on Violent Extremist Intentions

Perceived peer attitudes often influence young adult men’s violent attitudes and intentions, whereas the structure of peer networks can moderate this relationship. For example, people with more diverse social networks are less likely to adopt their close peers’ violent attitudes and behaviors. Despite that, there is currently limited research examining the role of structural features of peer networks in the relationship between perceived peer attitudes and violent extremist attitudes or intentions. Consequently, the current study sought to address this gap in research and answer the following questions: (1) To what extent are perceived peer attitudes, personal attitudes, and violent extremist intentions related to each other? (2) To what extent does the relationship between perceived peer attitudes and violent extremist intentions differ at different levels of social network diversity? The study sample consisted of 340 young adult men (i.e., 18-29 years old). Data collection took place via Amazon Mturk, an online-based crowdsourcing platform. Participants first indicated a social group with which they most strongly identify and listed their five closest male peers from the same group. Next, participants reported their violent extremist attitudes, intentions, and their perceptions of their peers’ opinions. Overall, perceived peer attitudes were positively and significantly associated with violent extremist intentions through their relationship with personal attitudes. The mediating effect, however, was partial: personal attitudes did not fully account for the total association. Furthermore, social network diversity moderated the relationship between personal and perceived peer attitudes: participants with more diverse social networks were less likely to hold beliefs similar to their perceived peer attitudes. In general, study findings were in line with past research on the impact of perceived peer attitudes and social network structure on violent outcomes. Thus, future studies should explore the potential role of other aspects of peer networks in the development of violent extremist attitudes and intentions. Regarding its policy implications, the study highlights the need for social-ecological approaches to counter violent extremism, offering young adult men opportunities for community involvement and growth of social ties

Globalization and social networks

Globalization is a universal phenomenon that not only makes domestic economies restructure, but also may impact other areas of local societies. This paper studies the effect of globalization on human relations, in particular on the formation of social networks, both bonding and bridging: I postulate that globalization induces labor market and workplace dynamics that would be destructive. Data come from the European and World Values Survey (1981-2008) on about 320’000 people’s values and attitudes, in this study spanning up to 22 years in about 80 countries, which have been matched with an index of economic globalization. In this pseudo micro panel I find robust evidence for a diminishing effect of globalization for bridging social networks with friends, but an enforcing one for bonding social networks among relatives. These results do not appear to be driven by a change in individuals’ preferences with respect to consuming and forming social ties. My findings are consistent with theories that claim growing physical distance and stronger reliance on family resources to lower the level of bridging social networks in society

Estimating parameters of a multipartite loglinear graph model via the EM algorithm

We will amalgamate the Rash model (for rectangular binary tables) and the newly introduced $\alpha$-$\beta$ models (for random undirected graphs) in the framework of a semiparametric probabilistic graph model. Our purpose is to give a partition of the vertices of an observed graph so that the generated subgraphs and bipartite graphs obey these models, where their strongly connected parameters give multiscale evaluation of the vertices at the same time. In this way, a heterogeneous version of the stochastic block model is built via mixtures of loglinear models and the parameters are estimated with a special EM iteration. In the context of social networks, the clusters can be identified with social groups and the parameters with attitudes of people of one group towards people of the other, which attitudes depend on the cluster memberships. The algorithm is applied to randomly generated and real-word data

How does social integration influence breast cancer control among urban African-American women? Results from a cross-sectional survey

<p>Abstract</p> <p>Background</p> <p>Although social integration is a well-established influence on health, less is known about how the specific types of social connection (social roles, social networks, and social support) influence knowledge, attitudes, and practices for specific prevention goals, and how to utilize these influences in interventions with priority populations. This research examined the prevalence of social roles, networks and support among 576 urban African-American women age 45–93 in East Baltimore, Maryland, and the association of these social factors with breast cancer related knowledge, attitudes, and practices.</p> <p>Methods</p> <p>Using data from 1997–1998 in-home interviews, we developed indices of six possible social roles, social networks of family, neighborhood and church, and instrumental and emotional social support. In multivariate models adjusting for age, education, and medical care, we examined the association of each social influence on breast cancer knowledge, attitudes, screening recency and intention, and treatment preferences.</p> <p>Results</p> <p>We found substantial variation in social integration among these women, with social integration positively associated with overall health and well-being. Social roles and networks were positively associated with screening knowledge, and emotional support and church networks were positively associated with attitudes conducive to early detection and treatment. In regard to screening behaviors, family networks were associated with both screening recency and intention. Women with greater church networks and emotional support held more conservative attitudes towards lumpectomy, reconstruction, and clinical trials.</p> <p>Conclusion</p> <p>Overall, social integration is a positive influence on breast cancer control and should be utilized where possible in interventions, including identifying surrogate mechanisms for support for subgroups without existing social resources.</p

Who is most influential? Adolescents’ intergroup attitudes and peer influence within a social network

Research has shown that adolescents' intergroup attitudes are subject to friends' influence, but it remains unknown if certain friends are more influential than others. Popular adolescents may be especially influential of their friends' intergroup attitudes because they can set peer norms. We examined several indicators of popularity in social networks as possible determinants of social influence: sociometric popularity, prestige popularity, being a clique leader, and frequency of contact with friends. Longitudinal analysis of adolescents' friendship networks (12-13 years, N = 837) allowed estimating influence of friends on adolescents' intergroup attitudes, while controlling for the tendency of adolescents to befriend peers with similar intergroup attitudes. Results showed that adolescents' intergroup attitudes changed in the direction of friends' intergroup attitudes. Only peers who are popular in terms of having many friends (sociometric popular) were especially influential of their friends' intergroup attitudes. These findings may inform future interventions aiming to reduce prejudice

Endangered language maintenance and revitalisation: the role of social networks

Numerous studies have found that high-density, ‘traditional’ social networks correlate with the use of low-status or local language varieties. Why some people maintain an ancestral language and transmit it to their children, while others abandon it, is a major issue in the study of language endangerment. This study focuses on Guernesiais, the endangered indigenous language of Guernsey, Channel Islands. Baseline data were collected using a questionnaire and semi-structured interviews; ethnographic methods then shed light on ideologies, attitudes, and the processes of language shift. Availability of interlocutors correlates strongly with fluency, for both native speakers and learners, but the increasing age and linguistic isolation of many native speakers contributes to both individual and societal language loss, along with other factors. Options for supporting (or reconstituting) social networks through language planning are examined

Transmission of vaccination attitudes and uptake based on social contagion theory: A scoping review

Vaccine hesitancy is a complex health problem, with various factors involved including the influence of an individual’s network. According to the Social Contagion Theory, attitudes and behaviours of an individual can be contagious to others in their social networks. This scoping review aims to collate evidence on how attitudes and vaccination uptake are spread within social networks. Databases of PubMed, PsycINFO, Embase, and Scopus were searched with the full text of 24 studies being screened. A narrative synthesis approach was used to collate the evidence and interpret findings. Eleven cross-sectional studies were included. Participants held more positive vaccination attitudes and greater likelihood to get vaccinated or vaccinate their child when they were frequently exposed to positive attitudes and frequently discussing vaccinations with family and friends. We also observed that vaccination uptake was decreased when family and friends were hesitant to take the vaccine. Homophily—the tendency of similar individuals to be connected in a social network—was identified as a significant factor that drives the results, especially with respect to race and ethnicity. This review highlights the key role that social networks play in shaping attitudes and vaccination uptake. Public health authorities should tailor interventions and involve family and friends to result in greater vaccination uptake
