Social networkers: Measuring and examining individual differences in propensity to connect with others

The research examined individual differences in people's propensity to connect with others (PCO). A measure of PCO, with components for making friends (strong ties), making acquaintances (weak ties), and joining others (bridging ties), was developed and tested in two studies involving 144 undergraduates and 197 health-care employees. PCO and its components were significantly positively associated with social network characteristics (including size, betweenness centrality, and brokerage) and indicators of personal adjustment including support received, attainment, well-being, influence, and suggestion-making. PCO had effects beyond those of major personality traits, and PCO components displayed distinctive relationships with work network characteristics.     

The Interplay Between Gender and Structure: Dynamics of Adolescent Friendships in Single‐Gender Classes and Mixed‐Gender Classes

This study reviews theories on striving for closure in adolescent networks related to trust issues of adolescents and further examines whether adolescents in mixed‐gender and single‐gender classes are different in striving for closure. Stochastic actor‐based models for network dynamics are applied to test our hypotheses based on longitudinal friendship nominations of 406 Taiwanese adolescents in mixed‐gender, all‐boy, and all‐girl classes. The results show that adolescents strive for closure through connections of friends' friends. Further, the results reveal that while the tendency toward closure is stronger for girls in mixed‐gender classes, such tendency toward closure is stronger in all‐boy classes than in all‐girl classes. Testing effects between types of classes supports the indications of variances in striving closure.     

Are women less career centric than men? Structure,culture, and identity investments

Some work/family scholars assume that gender differences in career centrality (i.e. the importance of career to one's identity) are a result of differential job characteristics and family demands; others trace these differences to pre-existing cultural orientations. Using the 2010 Generations of Talent data from 9210 employees working in 11 countries for 7 multinational companies, this study verifies the existence of gender differences in career centrality and explores structural and cultural explanations. Gender disparities in career centrality are modest, indicating that women's and men's identification with careers is more similar than is commonly asserted; the most pronounced (but still relatively small) disparities are observed in Japan and China. A large portion of the gender gap is explained by job characteristics, supporting structural explanations. Family demands contribute to explaining the gap as well, but the findings are unexpected: having minor children is associated with higher career centrality for both women and men. In support of cultural explanations, however, traditional gender beliefs are associated with lower career centrality, especially for women, while two job characteristics (job variety and peer relations) have distinct links to career centrality for women and men. Findings challenge the common assumption that family identities compete against work identities.     

Demographic and HIV status diversities as mechanisms of social integration and segregation among Black sexual and gender minorities enrolled in a community-based social network intervention

Drawing on a social integration and intersectionality framework, this study advances a dynamic network understanding of the mechanisms that enable differential patterns of within-group social integration and segregation among Black sexual and gender minorities (BSGM). Specifically, in a cohort of BSGM (18–35 years of age, n = 340) participating in a community-based network intervention for HIV prevention, we examine how sexual, gender, age, and HIV status diversities contribute to friendship formation and maintenance patterns over the 12-month study enrollment period. We found attenuated social integration (or social activity) among non-gay-identified and older BSGM and evidence of social segregation (or homophily) on the basis of sexual identity and age similarities. Accounting for the moderating effects of the intervention revealed that the attenuated integration of non-gay-identified and older BSGM were stronger for participants who received the peer leadership training, and integration challenges were also found for transgender BSGM who received the peer leadership training. Meanwhile, BSGM living with HIV who received the peer leadership training were significantly more integrated than their counterparts in the control arm. These findings help us understand the complicated social fabric among BSGM and the dynamics that interventions for this community may have to contend with or alter.     

Religion, social support, and health among the Japanese elderly

We address three issues in this paper: (1) Is religion related to self-rated health, (2) do these salubrious effects arise because religion encourages people to provide help to significant others, and (3) is the relationship between religion and helping others more evident among older men than elderly women? We analyze the relationships among religion, support giving, and health with data provided by a national probability sample of 2,153 older people in Japan who were interviewed face-to-face in 1996. Greater involvement in religion is associated with providing help to others more often, but these effects emerge for older men only. Regardless of gender, elders who provide assistance to others more often rate their health more favorably than older adults who are less involved in helping others. These results confirm that religion is related to health, and that helping others may explain at least part of the reason for this relationship.     

The social networks of academic performance in a student context of poverty in Mexico

Purpose: To describe the structure of the social network of junior high school students from a low socioeconomic status and assess the association between centrality measurements and academic performance. In the centrality positions (eigenvector, closeness, degree, and betweenness), the female gender and “only study” were significant predictors of high academic performance. The density of the student social network was presented by homophilic associations that hint at the existence of subcultures at school.     

Adolescent network positions and memory performance in adulthood: Evidence from sibling fixed effects models with sociometric network data

Although research has explored social factors influencing memory performance during adolescence, the impact of adolescent social network positions remains largely unknown. This study examines whether adolescent network position is associated with memory performance in adulthood, while also considering potential gender differences. The study used a sibling sample from the National Longitudinal Study of Adolescent to Adult Health (N = 2462) and employed sibling fixed effects models to account for unobserved family background factors, such as genetics, parental characteristics, family environment, and childhood neighborhood. Four dimensions of adolescent network position—i.e., popularity, sociality, degree centrality, and closeness centrality—were sociometrically assessed in schools. Memory performance in adulthood was measured using the Rey Auditory Verbal Learning Test. The sibling fixed effects estimates indicate that sociality, degree centrality, and closeness centrality are significantly associated with increased memory performance in adulthood, even after controlling for unobserved family heterogeneity as well as a set of individual-level covariates. In contrast, controlling for unobserved family heterogeneity attenuated the association for popularity, making it statistically insignificant. This study also provides evidence of gender differences in the association between social network position and memory performance. The associations for popularity, sociality, and degree centrality are more pronounced among men than women. This study’s findings highlight the importance of adolescent network positions as social determinants in shaping cognitive outcomes over the life course. Interventions that encourage positive peer interactions and reduce social isolation during adolescence may help improve cognitive health in the population.     

Network centrality and social movement media coverage: A two-mode network analytic approach

This article examines the relationship between structural location (namely, degree centrality) and news media coverage. Our central hypothesis is that the network centrality of social movement actors is positively associated with the prevalence of actors being cited in the print news media. This paper uses two-mode data from a communication network of environmentalists in British Columbia, and examines the relationship between their structural location and the frequency by which they are cited in newsprint media with regard to particular frames (about forest conservation, environmental protest, and related issues). We asked a sample of social movement participants about their ties to a target list of relatively high profile actors (environmental activists). We turned the resulting network matrix into a bipartite graph that examined the relationships amongst the target actors vis a vis the respondents. Next we calculated point in-degree for the target actors. For the target actors we also have data from a representative sample of 957 print news articles about forestry and conservation of old growth forests in British Columbia. We compare the effects of network centrality of the target actor versus several attributes of the target actors (gender, level of radicalism, leadership status) on the amount of media coverage that each of the target actors receives. We find that network centrality is associated with media coverage controlling for actor attributes. We discuss theoretical implications of this research. Finally, we also discuss the methodological pros and cons of using a “target name roster” to construct two-mode data on social movement activists.     

Learning in social networks: Selecting profitable choices among alternatives of uncertain profitability in various networks

Social capital theory assumes that information is valuable. However, only rarely is this value explicitly modeled, and there are few examples of empirical tests of mechanisms that connect social network structure to valuable information. We model an individual decision problem in which individuals make choices that yield uncertain outcomes. The individuals can learn about the profitability of options from their own choices and from the network. We generate computer-simulated data to derive hypotheses about the effect of network characteristics on making profitable choices. We conduct a laboratory experiment to empirically test these hypotheses and find that, at the individual level, degree centrality has a positive effect on making profitable choices whereas betweenness centrality has no effect. At the network level, density has a positive effect on making profitable choices, whereas centralization does not have an effect.     

Geodesic based centrality: Unifying the local and the global

A variety of node-level centrality measures, including purely structural measures (such as degree and closeness centrality) and measures incorporating characteristics of actors (such as the Blau's measure of heterogeneity) have been developed to measure a person's access to resources held by others. Each of these node-level measures can be placed on a continuum depending on whether they focus only on ego's direct contacts (e.g. degree centrality and Blau's measure of heterogeneity), or whether they also incorporate connections to others at longer distances in the network (e.g. closeness centrality or betweenness centrality). In this paper we propose generalized measures, where a tuning parameter δ regulates the relative impact of resources held by more close versus more distant others. We first show how, when a specific δ is chosen degree-centrality and reciprocal closeness centrality are two specific instances of this more general measure. We then demonstrate how a similar approach can be applied to node-level measures that incorporate attributes. When more or less weight is given to other nodes at longer distances with specific characteristics, a generalized measure of resource-richness and a generalized measure for diversity among one's connections can be obtained (following Blau's measure of heterogeneity). Finally, we show how this approach can also be applied to betweenness centrality to focus on more local (ego) betweenness or global (Freeman) betweenness. The importance of the choice of δ is illustrated on some classic network datasets.     

A comparison of email networks and off-line social networks: A study of a medium-sized bank

Recently there has been a surge in the availability of online data concerning the connections between people, and these online data are now widely used to map the social structure of communities. There has been little research, however, on how these new types of relational data correspond to classical measures of social networks. To fill this gap, we contrast the structure of an email network with the underlying friendship, communication, and advice seeking networks. Our study is an explorative case study of a bank, and our data contains emails among employees and a survey of the ego networks of the employees. Through calculating correlations with QAP standard errors and estimating exponential random graph (ERG) models, we find that although the email network is related to the survey-based social networks, email networks are also significantly different: while off-line social networks are strongly shaped by gender, tenure, and hierarchical boundaries, the role of these boundaries are much weaker in the email network.     

Gender,Social Bond,and Academic Cheating in Japan*

There is evidence that females are less likely to cheat than males on college campuses. A frequently offered but still untested explanation is that females, with a stronger sense of responsibility for the maintenance of social relationships, tend to develop a stronger bond to a conventional society—a key explanatory concept in Hirschi’s (1969) social control theory. With academic cheating as the dependent variable, we test the hypotheses that the four elements of social bond are the intervening variables linking gender to such dishonesty among Japanese students who, due to their stronger orientation toward masculinity on Hofstede’s (1980) scale of gender role separation, are subject to more gender distinct socialization, leading to greater gender differences in the strength of social bond than those previously reported in the United States. The analysis provides rather limited support for the theory, most of which is due to the stronger belief in the legitimacy of societal rules among the females.     

Real Gender: Identity,Loss, and the Capacity to Feel Real

This article concerns gender and feeling real. Beginning with Judith Butler’s deconstruction of gender as an ontological category, it argues that the subjective experience of gender as real has been underaccounted for. By reviewing Butler’s work on gender melancholy and then elaborating psychoanalytic theories of identification and reality, this article links feeling real to the dual capacities to both separate from and connect with the object. To illustrate the implications for thinking gender identity and transformation, it concludes with a reading of Miles Walser’s poem about the name discarded in a gender transition.     

The Role of Supervisory Referral in Employee Assistance Programs

Abstract

A growing number of organizations offer Employee Assistance Programs (EAPs) to help employees with their personal problems. Many organizations rely on their supervisors to help identify and refer troubled employees to the EAP for assistance, yet very little conclusive evidence exists regarding the factors that influence whether or not supervisors identify and intervene with troubled employees. A previous review of the literature (Nord & Littrell, 1989) found that the following variables were consistently related to referral: (a) degree of management support for the EAP, (b) gender of supervisor, (c) gender of subordinate, (d) existence of a supervisor network, (e) occupational category of the employees supervised, (f) social distance between supervisor and troubled employee, (g) supervisors' attitude toward their role in referral, and (h) supervisor knowledge of the EAP. However, results of some of the studies reviewed for the current paper were inconsistent with Nord and Littrell's (1989) findings. Additional research is needed in this area, including research on the effectiveness of EAP supervisory training, in order to provide guidelines for the administration of effective EAP programs.     

The feminine style,the male influence,and the paradox of gendered political blogspace

This article explores gender differences in political communication among blogging politicians. The article sets out to explore two baseline questions: (1) Are distinct gendered ‘blogstyles’ to be found among political representatives? and (2) How do gender and gendered blogstyles interplay and affect the impact of political blogs? The empirical study draws on a survey targeting blogging politicians in Sweden (N?=?523). The analysis identifies substantial differences in how female and male politicians communicate in the blogosphere as well as the outcomes in terms of feedback and impact. Female politicians, to a greater degree than their male counterparts, utilize blogging for the purpose of fostering a stronger connection with their readers as well as to enquire about ideas and policy perspectives. This strategy seems to be successful for fostering qualitative feedback from readers; yet, female bloggers have far less impact than their male colleges. We discuss two potential understandings of these results: relating to gender stereotypes and the network power structure of the blogosphere.     

Secondhand social capital: Boundary spanning,secondhand closure,and individual performance

We move beyond the performance returns of individuals’ direct network connections to study the effects of “secondhand” social capital, i.e., from the networks of one’s contacts. We propose that certain colleagues may be more valuable to one’s job performance than others when their spillovers of novel information combine with spillovers of the cooperation needed to obtain that novelty. In a study of 1273 research and development employees across 16 business units, we find that the most benefit to one’s own performance comes from having ties that span business units and that also include secondhand closure (i.e., where one’s contacts are each embedded in a constrained, dense network). Bridging the organizational boundary provides the novelty; and secondhand closure provides the cooperation. Further, by examining who in the network is constraining these contacts, we are able to trace their cooperative motivation both to reputational and organizational identity concerns, which each create a spillover of cooperation toward the focal individual, who reaps the returns.     

Centrality in social networks conceptual clarification

The intuitive background for measures of structural centrality in social networks is reviewed and existing measures are evaluated in terms of their consistency with intuitions and their interpretability.Three distinct intuitive conceptions of centrality are uncovered and existing measures are refined to embody these conceptions. Three measures are developed for each concept, one absolute and one relative measure of the centrality of positions in a network, and one reflecting the degree of centralization of the entire network. The implications of these measures for the experimental study of small groups is examined.     

Reliability of measures of centrality and prominence

This paper evaluates the reliability of measures of centrality and prominence of social networks among high school students. The authors present and discuss results from eight experiments. Four types of social support: (1) instrumental support, (2) informational support, (3) social companionship, and (4) emotional support—were measured three times within each class. Four measurement scales: (1) binary, (2) categorical, (3) categorical with labels and (4) line production—were applied. Reliability of in- and out-degree, in- and out-closeness, betweenness and flow betweenness was estimated by the Pearson correlation coefficient. Meta analysis of factors affecting the test-retest reliability of measures of centrality and prominence was done by multiple classification analysis. Results show that,

• -Global measures (considering direct and indirect choices) are more sensitive to measurement errors than local measures (considering only direct choices).
• -In-measures are more stable than out-measures.
• -Among types of social support, emotional support gives the least stable measures of centrality and prominence, whereas social companionship gives the most stable results.
• -The reliability of centrality and prominence measures is higher when the network is denser.

     

Egocentric and sociocentric measures of network centrality

Egocentric centrality measures (for data on a node’s first-order zone) parallel to Freeman’s [Social Networks 1 (1979) 215] centrality measures for complete (sociocentric) network data are considered. Degree-based centrality is in principle identical for egocentric and sociocentric network data. A closeness measure is uninformative for egocentric data, since all geodesic distances from ego to other nodes in the first-order zone are 1 by definition. The extent to which egocentric and sociocentric versions of Freeman’s betweenness centrality measure correspond is explored empirically. Across seventeen diverse networks, that correspondence is found to be relatively close—though variations in egocentric network composition do lead to some notable differences in egocentric and sociocentric betweennness. The findings suggest that research design has a relatively modest impact on assessing the relative betweenness of nodes, and that a betweenness measure based on egocentric network data could be a reliable substitute for Freeman’s betweenness measure when it is not practical to collect complete network data. However, differences in the research methods used in sociocentric and egocentric studies could lead to additional differences in the respective betweenness centrality measures.     

Work–family Conflict and Job Satisfaction Relationship: The Roles of Gender and Interpretive Habits

This study examined the effects of gender and interpretive habits on the relationship between work–family conflict (WFC) and job satisfaction. The results of the analysis of the data collected from 286 academic personnel suggest that interpretive habits moderate the relationship between WFC and job satisfaction such that the negative effect of WFC and job satisfaction is stronger for employees focusing highly on deficiency, with high necessitating, and low skill recognition, referred to as stress‐predisposing interpretive habits. Furthermore, gender was found to have an influence on the role of interpretive habits in the WFC–job satisfaction relationship. Specifically, WFC had a negative association with job satisfaction for stress‐predisposed male employees while no relationship was found between WFC and job satisfaction for men with a low focus on deficiency, low necessitating and high skill recognition namely, stress‐resilient interpretive habits. Moreover, although WFC had a negative association with job satisfaction for female employees, this relationship was even stronger for stress‐resilient females. The implications of the findings and suggestions for future studies are discussed.
