What is(n’t) a friend? Dimensions of the friendship concept among adolescents

Much research in network analysis of adolescent friendships assumes that friendships represent liking and social interaction, friendships are directed, and friendships are equivalent to one another. This study investigates the meaning of friendship for eight diverse cohorts of sixth graders. Analysis of focus group and survey data suggests that these adolescents construe friendship as a multidimensional role relation composed primarily of relational norms, expectations for mutual behavior. Their friendship definitions may also include mutual liking and interaction, and other structural expectations such as reciprocity, homophily, and transitivity. Lastly, boys and girls weight these dimensions differently in defining friendship.     

Ethnic segregation of friendship networks in school: Testing a rational-choice argument of differences in ethnic homophily between classroom- and grade-level networks

Adolescents’ school-based friendship networks tend to be segregated along ethnic lines. But few studies have examined whether variation in network boundaries affects the degree of ethnic friendship segregation. We use rational-choice theory to argue that ethnic homophily is more pronounced for friendships between classrooms than for those within classrooms. We empirically test this hypothesis using two-wave German panel data (N = 1258) and stochastic actor-oriented models (RSiena). In line with our theoretical argument, we find that the tendency to form same-ethnic friendships is indeed stronger at the grade level, which translates into stronger ethnic segregation in friendship networks at the grade level than at the classroom level. Implications for research on ethnic segregation in school-based friendship networks are discussed.     

Who is fighting with whom? How ethnic origin shapes friendship,dislike, and physical violence relations in German secondary schools

This study examines the role of ethnic background for friendship, dislike, and violence networks in secondary school. We analyze data on multiple networks from a large-scale study of more than 2500 seventh-graders in Germany. In addition to ethnic homophily in friendship networks, our results reveal a tendency among students to dislike ethnic outgroup members (ethnic heterophobia). However, students are more likely to engage in violence towards same-ethnic peers than outgroup members. This is partly due to the greater prevalence of violence among students who are close in the friendship network and students who spend time together outside of school. Moreover, schools marked by stronger ethnic homophily in friendships tend to display higher levels of ethnic heterophobia but exhibit higher levels of intra-ethnic rather than inter-ethnic violence.Keywords: Ethnic homophily; Violence; School networks; Multiplex networks; Exponential random graph models; Bullying     

Friendship and Conformity in Group Opinions: Juror Verdict Change in Mock Juries

Social psychological research on group processes has consistently shown that group members adjust their views to conform to dominant and/or socially desirable stances. Studies are less clear, though, on how friendships within groups impact this tendency. Some studies suggest greater group cohesion leads to more conformity; other studies suggest friendship lessens the pressure to agree on certain issues. In this study, we use mock juries to test the impact of varying levels of friendship on jurors’ propensities to change their verdicts to the dominant position (in this case acquittal, or a “not guilty” verdict). Our findings show that distant friendships among jurors increase the odds of conforming to acquittal; but close friendships decrease the odds of conformity. We discuss the implications of our findings for understanding group processes and conformity as well as for jury research.     

Bridging and Bonding in the Academic Melting Pot: Cultural Resources and Network Diversity

Understanding how cultural resources shape the formation of social networks is a methodological challenge as well as a theoretical objective, and both are yet to be met. In this study, sociability on college campuses is modeled as a process in which students’ prior cultural experiences and the current social structure of the student body work together, affecting the likelihood of friendships that take place within or across racial boundaries. Structural and cultural perspectives are surveyed to develop hypotheses concerning the determinants of interracial friendship, and these hypotheses are tested against a sample of 3,392 students from the National Longitudinal Study of Freshmen. The results suggest that religiosity, political activism, high arts participation, and athletic activities undertaken prior to college affect the diversity of social networks formed in the first year, but work in different directions. The effects of these cultural experiences may be explained by the racial organization of cultural activity on campus.     

Girls’ friendships as habitus in an elite,middle-class secondary school in Ireland

This study examines gendered and classed friendships in a predominantly middle-class, girls' secondary school in the southern region of the Republic of Ireland. Bourdieu's (1977) concept of habitus, interactively, with Gidden's (1984) concept of practical consciousness, and Gambetta's (1987) intentional rational choice informed the conceptual framework for the study. Narrative sources yielded data about girls' friendships and peer interactions inside and outside of school. The social class and habitus of each of the girls mediated their friendship formation and friendship choice. Data sources highlight that the middle-class girls' friendships were situated in fluid and multiple cliques; given their hegemonic positionality within the school. Contrastingly, working-class girls' friendships were situated in a contained and single clique, often evidenced by their resistance to the institutional habitus. The ways in which these peer friendships operated as powerful shapers of the girls' actions and identities is discussed. This paper provides examples of the nuanced ways that girls' friendships are developed and maintained based on conformity or resistance to the school norms and expectations of academic success. Importantly, findings evidence the differentiated and instrumental use of friendships among the middle-class and working-class girls in a competitive, elite school setting.     

Adding valued data to social network measures: Does it add to associations with adolescent substance use?

This research examines whether adding information about adolescent friendships (feeling of closeness to friend, visits to friend's home, interaction outside school, and parent involvement in the friendship) to social network measures increases associations with adolescent substance use. In 2002, friendship nominations were obtained from more than 4700 students in grades 6 to 8 in 13 schools. Social network measures weighted and unweighted for the valued information were created from those data and compared. The findings suggest that, although non-valued network measures and ego substance use were associated, the valued network measures did not add to those associations.     

The relationship between mothers' social networks and severe domestic violence: a test of the social isolation hypothesis

To understand the relationship between characteristics of mothers' social networks and domestic violence, battered mothers who were severely assaulted were compared to battered mothers who were not severely assaulted and mothers who were not assaulted. The results showed that all three groups of mothers had several family members in their social networks with whom they had frequent contact during the past month. No differences were found between the groups on the number of family members who gave emotional support. However, the mothers who were severely assaulted had fewer friends, fewer contacts with their friends, fewer long-term friendships, and fewer friends who really listened to them than did the nonbattered mothers and the battered mothers who were not severely assaulted. Batterers may be more successful in disrupting friendship ties than family ties.     

The Emergence and Stability of Groups in Social Networks

An important puzzle in social network research is to explain how macro-level structures emerge from micro-level network processes. Explaining the emergence and stability of structural groups in social networks is particularly difficult for two reasons. First, because groups are characterized both by high connectedness within (group cohesion) and lack of connectedness between them (group boundaries). Second, because a large number of theoretical micro-level network processes contribute to their emergence. We argue that traditional social network theories that are concerned with the evolution of positive relations (forces of attraction) are not sufficient to explain the emergence of groups because they lack mechanisms explaining the emergence of group boundaries. Models that additionally account for the evolution of negative ties (forces of repulsion) may be better suited to explain the emergence and stability of groups. We build a theoretical model and illustrate its usefulness by fitting stochastic actor-oriented models (SAOMs) to empirical data of co-evolving networks of friendship and dislike among 479 secondary-school students. The SAOMs include a number of newly developed effects expressing the co-evolution between positive and negative ties. We then simulate networks from the estimated models to explore the micro-macro link. We find that a model that considers forces of attraction and repulsion simultaneously is better at explaining groups in social networks. In the long run, however, the empirically informed simulations generate networks that are too stylized to be realistic, raising further questions about model degeneracy and time heterogeneity of group processes.     

‘Self’ (ziji), ‘others’ (taren) and ‘collective’ (jiti): Friendships at school embedded with China's Confucian–collectivist sociocultural values

Friendship, an important type of interpersonal relationship, has been studied in various disciplines. When studying friendship, sociologists highlight the importance of placing friendships in context to build up a connection between friendship, a type of interpersonal relationship between individuals, and the surrounding social and cultural environment. In sociological studies of friendship, children's friendships in the Chinese context have not been explored thoroughly. To contribute to closing this gap, this article places children's peer friendships in a rural Chinese primary boarding school context and focuses on exploring Chinese Confucian – collectivist sociocultural values that emerged in these children's daily practices of peer friendships.     

Same‐Race Friendships and School Attachment: Demonstrating the Interaction Between Personal Network and School Composition1

Previous research has demonstrated that students are strongly attached to school when many same‐race peers are present. This study extends the literature by considering students’ immediate social environment at school—egocentric friendship networks. I hypothesized that same‐race friendships contribute to school attachment by increasing the amount of support that students receive for their racial backgrounds in direct interactions. Further, the association between same‐race friendships and school attachment should be stronger when the school includes many same‐race peers because the organizational condition increases the ability of same‐race friendships to connect students to the major components of school‐wide networks and reduces perceived racial contrast between friends and nonfriend peers. Statistical analysis of the National Longitudinal Study of Adolescent Health (Add Health) provided some support for these hypotheses, but white, black, Hispanic, and Asian students showed somewhat different patterns, suggesting group differences in how students develop and view same‐race friendships. The study highlights the importance of individual agency in navigating the multileveled social environment as well as the ability of organizational contexts to shift emotional consequences of personal relationships.     

An agent-based random-utility-maximization model to generate social networks with transitivity in geographic space

Stochastic actor-based approaches receive increasing interest in the generation of social networks for simulation in time and space. Existing models however cannot be readily integrated in agent-based models that assume random-utility-maximizing behavior of agents. We propose an agent-based model to generate social networks explicitly in geographic space which is formulated in the random-utility-maximizing (RUM) framework. The proposed model consists of a friendship formation mechanism and a component to simulate social encounters in a population. We show how transitivity can be incorporated in both components and how the model can be estimated based on data of personal networks using likelihood estimation. In an application to the Swiss context, we demonstrate the estimation and ability of the model to reproduce relevant characteristics of networks, such as geographic proximity, attribute similarity (homophily), size of personal networks (degree distribution) and clustering (transitivity). We conclude that the proposed social-network model fits seamlessly in existing large-scale micro-simulation systems which assume RUM behavior of agents.     

Avoidance,antipathy, and aggression: A three-wave longitudinal network study on negative networks,status, and heteromisos

Our aim is to explain negative networks in Dutch high schools, using three-wave stochastic actor oriented models (SAOMs). We differentiate between avoidance, antipathy, and aggression based on how costly and visible these behaviours are. Our results show that pupils’ ethnicity does not explain negative ties. Moreover, we do not find that negative ties form archetypical social hierarchies, formed by networks that are asymmetrical and transitive. Instead, we find positive effects of reciprocity on avoidance, antipathy, and aggression, and we find no effects of transitivity. Rather than allowing themselves to be dominated by their classmates, pupils fight back and reciprocate negative behaviour. We further show that some pupils behave negatively to a lot of their classmates, and that some pupils are treated negatively by many classmates. These results require us to reconsider what status hierarchies look like. Finally, we explore the extent to which the avoidance, antipathy, and aggression networks co-evolve.     

Friendship Talk as Identity Work: Defining the Self Through Friend Relationships

This paper places friendships at the center of individuals' identity work, examining how individuals construct self‐identities through their talk about friend relationships and networks. We conceptualize this “friendship talk” as a subcategory of identity talk. From interviews with emerging adults, we find three strategies of friendship talk: envisioning self through others, betterment distancing, and situating with networks. These strategies demonstrate unique ways identity construction occurs through talk about friends. Individuals verbally connect with and separate from friends while constructing desired selves and moral identities. We suggest that friendship talk strategies may be generic social processes that apply beyond emerging adulthood.     

Old Lesbians in the UK: Community and Friendship

Drawing on data from the first large-scale comprehensive study of older lesbian life in the United Kingdom, this article explores the nature of friendship and community among old lesbians. Strong friendship bonds and social networking emerge as key features of old lesbian culture. In particular the article focuses on “chosen families,” including relationships with ex-lovers, and on the extensive network of both organized and informal social groups that continue to structure and support a sense of community among old lesbians. It shows the lasting importance of friendships and social structures formed earlier in life against a background of stigmatization, homophobia, and heterosexism, and argues for the recognition of these communities of identity by those who care for older people.     

The Interplay Between Adolescents' Friendships and the Exchange of Help: A Longitudinal Multiplex Social Network Study

The aim of this study was to unravel the interrelatedness of friendship and help, and to examine the characteristics of friendship and help networks. The effects of mutual versus one‐sided help relations on friendship initiation and maintenance, and vice versa, were examined. Friendship and help networks were analyzed (N = 953 students; 41 classrooms; M_age = 12.7). The results illustrate that friendship and help networks show some similarities, but only partly overlap and have distinct characteristics. Longitudinal multiplex social network analyses showed that mutual help was important for the maintenance of friendship, but not for the initiation of friendship. Further, particularly mutual friendships provided a context in which help took place. Implications of these findings are discussed.     

Assessing structural correlates to social capital in Facebook ego networks

Research in computer-mediated communication has consistently asserted that Facebook use is positively correlated with social capital. This research has drawn primarily on Williams’ (2006) bridging and bonding scales as well as behavioral attributes such as civic engagement. Yet, as social capital is inherently a structural construct, it is surprising that so little work has been done relating social capital to social structure as captured by social network site (SNS) Friendship networks. Facebook is particularly well-suited to support the examination of structure at the ego level since the networks articulated on Facebook tend to be large, dense, and indicative of many offline foci (e.g., coworkers, friends from high school). Assuming that each one of these foci only partially overlap, we initially present two hypotheses related to Facebook social networks and social capital: more foci are associated with perceptions of greater bridging social capital and more closure is associated with greater bonding social capital. Using a study of 235 employees at a Midwestern American university, we test these hypotheses alongside self-reported measures of activity on the site. Our results only partially confirm these hypotheses. In particular, using a widely used measure of closure (transitivity) we observe a strong and persistent negative relationship to bonding social capital. Although this finding is initially counter-intuitive it is easily explained by considering the topology of Facebook personal networks: networks with primarily closed triads tend to be networks with tightly bound foci (such as everyone from high school knowing each other) and few connections between foci. Networks with primarily open triads signify many crosscutting friendships across foci. Therefore, bonding social capital appears to be less tied to local clustering than to global cohesion.     

Testing transitivity in graphs

The situation is considered whether a graph can be assumed to have been generated by a random model capturing more transitivity than a simple uniform model. Three different test quantities based on induced triad counts and local densities are used. A simulation study is made in order to estimate critical values of the tests for different significance levels. The powers of the tests are estimated against the Bernoulli triangle model, a simple random graph model in which the clustering and transitivity is higher than in the uniform model. The test based on the proportion of transitive triads has the highest power in most cases, but the test based on density difference (the difference between mean local density and overall graph density) is more powerful against models with high transitivity. The tests are applied to a large set of school class sociograms. In this situation, uniform randomness is rejected in favor of transitivity most frequently when the test based on the proportion of transitive triads out of the non-vacuously transitive triads is used. It is concluded that this test, which also performed reasonably well when applied to random data, is the best at detecting transitivity. Although the Bernoulli triangle model fits to the empirical data set better than the uniform model, there are fewer truly intransitive triads in the data than could be expected under either of the models.     

The role of reciprocation in social network formation,with an application to LiveJournal

This paper deals with the role of reciprocation in the formation of individuals’ social networks. We follow the activity of a panel of bloggers over more than a year and investigate the extent to which initiating a relation brings about its reciprocation. We adapt a standard capital investment model to study how reciprocation affects the build-up of the individual social capital of bloggers, as measured by their links and interactions with others. This allows us to measure the role of content production and relationship building in the dynamics of online social networks and to distinguish between the social networking and media aspects of blogging.     

Workplace friendships among social work,counseling, and human service educators: Exploring the impact of sexual orientation and friendships in workplace empowerment

Workplace friendships are deliberate bonds between people in the workplace in which various degrees of confidence, care, emotional support, solidarity, honesty, and trust are shared. For lesbian, gay, and bisexual (LGB) academics in higher education, such friendships may be particularly important as sources of social and institutional support. In this study, the authors examine the relationship between workplace friendships and workplace empowerment among a sample (N?=?204) of LGB and non-LGB educators in social work, counseling, and human services. The findings, taken from this sample of university educators, indicate that sexual orientation and workplace friendship opportunities can predict workplace empowerment. Implications of the study are that workplace behavioral health practice and research that supports LGB and non-LGB workers in developing meaningful relationships at work can positively impact the higher education workplace.
