Exploiting User Friendship Networks for User Identification across Social Networks

Identifying offline entities corresponding to multiple virtual accounts of users across social networks is crucial for the development of related fields, such as user recommendation system, network security, and user behavior pattern analysis. The data generated by users on multiple social networks has similarities. Thus, the concept of symmetry can be used to analyze user-generated information for user identification. In this paper, we propose a friendship networks-based user identification across social networks algorithm (FNUI), which performs the similarity of multi-hop neighbor nodes of a user to characterize the information redundancy in the friend networks fully. Subsequently, a gradient descent algorithm is used to optimize the contribution of the user’s multi-hop nodes in the user identification process. Ultimately, user identification is achieved in conjunction with the Gale–Shapley matching algorithm. Experimental results show that compared with baselines, such as friend relationship-based user identification (FRUI) and friendship learning-based user identification (FBI): (1) The contribution of single-hop neighbor nodes in the user identification process is higher than other multi-hop neighbor nodes; (2) The redundancy of information contained in multi-hop neighbor nodes has a more significant impact on user identification; (3) The precision rate, recall rate, comprehensive evaluation index (F1), and area under curve (AUC) of user identification have been improved.

Service, Activism, and Friendships in High School: A Longitudinal Social Network Analysis of Peer Influence and Critical Beliefs

Scholars acknowledge that friends shape youth civic engagement, but the relative contribution of peer influence and critical beliefs to civic behaviors has yet to be disaggregated. Informed by sociopolitical development and critical consciousness theories, the present study used longitudinal social network analysis to examine peer socialization and adolescents’ awareness of systemic inequities in relation to participation in service and activist activities at a high school serving primarily low-income Latinx youth. Students were surveyed in May 2019 and May 2020 (N = 354; 51% female; in 2019, Mage = 15.9, age range 14.4 to 18.5). The results yielded evidence of peer influence on service activities, but not activism or perceptions of inequities. In contrast, adolescents’ perception of inequities predicted their activist behavior, but not service, after controlling for network effects and individual covariates. The school provided scaffolding for service activities, but not activist activities, potentially explaining the salience of service participation in youth friendship networks.

Communicative Coping and Friendship Among Persons Living With Dementia: Findings From Long-Term Care

The study of identity is central to many disciplines, however there is a special link that connects language and discourse to identities. The way people speak reveals a lot about who they are. Through discourse and communication individuals convey and negotiate their sense of self (de Fina, 2020). Regardless of cognitive status, persons living with dementia (PLWD) use language to construct for themselves a social identity of being included in friendship networks (de Medeiros et al., 2011). This paper uses data from the Friendship Study to examine the use of such communicative coping behavior (CCB) for friendship formation. Ethnographic observations of PLWD were conducted in a Long-Term Care residential setting. Sociolinguistic discourse analysis of verbatim transcripts with reference to the CCB Checklist (Saunders et al., 2016) reveal evidence of CCB use. Results suggest that different types of CCBs were used to construct identity and negotiate friendship challenges in different contexts.

You are not alone: Smartphone use, friendship satisfaction, and anxiety during the COVID-19 crisis

Due to ‘stay-at-home’ measures, individuals increasingly relied on smartphones for social connection and for obtaining information about the COVID-19 pandemic. In a two-wave panel survey ( NTime2 = 416), we investigated associations between different types of smartphone use (i.e., communicative and non-communicative), friendship satisfaction, and anxiety during the first lockdown in Austria. Our findings revealed that communicative smartphone use increased friendship satisfaction over time, validating how smartphones can be a positive influence in difficult times. Friendship satisfaction decreased anxiety after one month, signaling the importance of strong friendship networks during the crisis. Contrary to our expectations, non-communicative smartphone use had no effects on friendship satisfaction or anxiety over time. Reciprocal effects showed that anxiety increased both types of smartphone use over time. These findings are discussed in the context of mobile media effects related to the COVID-19 pandemic.

Men’s Help-Seeking for Distress: Navigating Varied Pathways and Practices

There is a widely accepted dominant narrative surrounding men’s mental health help-seeking, that men are less likely to pursue formal mental health support on account of hegemonic masculine ideals that limit emotional expression and vulnerability. Across the literature, little attention has been given to the varied ways in which men can and will seek out help when experiencing mental health troubles. This paper reports findings from a qualitative study of men’s experiences of distress, specifically focused on their help-seeking and everyday coping and management of distress. Between 2016 and 2017, 38 individual interviews were carried out in South Wales, United Kingdom, with men of a range of ages (21–74 years of age) and social backgrounds. Analysis identifies nuanced help-seeking practices and pathways, emphasizing ways in which men can and will engage with mental health support. Some men struggled with articulating personal issues in mental health terms, and some portrayed ambivalence to help-seeking, yet at the same time reconstructed help-seeking to positively align with masculine values. The paper further highlights the significant influence of familial and friendship networks in the help-seeking process as well as the value of therapy for men experiencing mental health difficulties, challenging the idea that masculinity inhibits the disclosure of emotional problems. Awareness of the diversity of ways in which men can actively engage with their mental health is needed so that mental health support interventions and practitioners can best reach out to men experiencing distress and provide gender-sensitive support suitable to a range of different men.

Peer Network Processes in Adolescents’ Health Lifestyles

Combining theories of health lifestyles—interrelated health behaviors arising from group-based identities—with those of network and behavior change, we investigated network characteristics of health lifestyles and the role of influence and selection processes underlying these characteristics. We examined these questions in two high schools using longitudinal, complete friendship network data from the National Longitudinal Study of Adolescent to Adult Health. Latent class analyses characterized each school’s predominant health lifestyles using several health behavior domains. School-specific stochastic actor-based models evaluated the bidirectional relationship between friendship networks and health lifestyles. Predominant lifestyles remained stable within schools over time, even as individuals transitioned between lifestyles. Friends displayed greater similarity in health lifestyles than nonfriend dyads. Similarities resulted primarily from teens’ selection of friends with similar lifestyles but also from teens influencing their peers’ lifestyles. This study demonstrates the salience of health lifestyles for adolescent development and friendship networks.

Childbirth in Transit

This chapter ethnographically explores childbirth practices at Taljai, a large urban slum on the southern outskirts of Pune city in India. Based on women’s recounting of their personal experiences and social relationships surrounding birth-giving at home, this chapter describes childbirth at Taljai as unstable, mirroring the migrant lives of women. Women’s migrant lives at Taljai are precarious and subject to material paucity and systemic violence, defined by strong internal negotiation and sociability surrounding their birth-giving practices at home. While homebirths are predicated on friendship networks among women, clinical births either indicate individual exclusion from women’s groups at Taljai or women’s active choice to avoid being controlled by other women. This chapter explores the tight gendered sociability surrounding homebirth at Taljai, demonstrating how women amalgamate experiences of self-birthing at home with home-birthing at the slum, instrumentalizing childbirth rituals as a means of social bonding.

Arrested Friendships? Justice Involvement and Interpersonal Exclusion among Rural Youth

Objectives: We examine the impacts of adolescent arrest on friendship networks. In particular, we extend labeling theory by testing hypotheses for three potential mechanisms of interpersonal exclusion related to the stigma of arrest: rejection, withdrawal, and homophily. Method: We use longitudinal data on 48 peer networks from PROSPER, a study of rural youth followed through middle and high school. We test our hypotheses using stochastic actor–based models. Results: Our findings suggest that arrested youth are less likely to receive friendship ties from school peers and are also less likely to extend them. Moreover, these negative associations are attenuated by higher levels of risky behaviors among peers, suggesting that results are driven by exclusion from normative rather than nonnormative friendships. We find evidence of homophily on arrest but it appears to be driven by other selection mechanisms rather than a direct preference for similarity on arrest. Conclusions: Overall, our findings speak to how an arrest may foster social exclusion in rural schools, thereby limiting social capital for already disadvantaged youth.
