Despite being one of the foundational theories of signed (positive/negative) tie formation, the evidence for balance theory is far from conclusive. A recent promising alternative is status theory, but a theoretical and explanatory gap still remains, with a dearth of theories and evidence. We put forward and test eight separate theories of signed tie formation on two face-to-face networks of friendship and esteem of 282 students. We use dimension reduction (factor analysis) on the results tables comparing the predictions of these eight theories for 50 ERGM parameters with our estimated models. We find three main paradigms explain the majority of signed network formation: balance, status, and homophily.  相似文献

Much research has explored the role of social networks in promoting health through the provision of social support. However, little work has examined how social networks themselves may be structured by health. This article investigates the link between individuals' health and the characteristics of their social network positions. We first develop theoretical predictions for how health may influence the structure of adolescent networks. We then test these predictions using longitudinal analysis of the National Longitudinal Study of Adolescent Health (Add Health). We find important relationships between the health status of adolescents and the characteristics of the social network positions within which they are embedded. Overall we find that adolescents in poor health form smaller local networks and occupy less central global positions than their healthy peers. These results also have implications for social network research, expanding the scope of factors responsible for the network positions individuals occupy.  相似文献

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.  相似文献

There is little research on how specific parent–adolescent sexual communication topics influence Latino/a youth's sexual behaviors, and how gender and generational status may moderate effects. This study examined effects of three different messages on intercourse and condom use among 1,944 Latino/as from the National Longitudinal Study of Adolescent Health (T1 mean age = 15.46; SD = 1.50). Results indicated discussing health consequences predicted higher odds of intercourse 1 year later across gender and generation groups. Birth control recommendation effects on subsequent intercourse and condom use differed by generational status and gender. Results indicated that message content is important for understanding effects of parent–adolescent sex communication on adolescents' behavior and underscored the need to consider gender and generational status in Latino/a parent–adolescent sexual communication studies.  相似文献

The emergence of disliking relations depends on how adolescents perceive the relative informal status of their peers. This phenomenon is examined on a longitudinal sample using dynamic network analysis (585 students across 16 classes in five schools). As hypothesized, individuals dislike those who they look down on (disdain), and conform to others by disliking those who they perceive as being looked down on by their peers (conformity). The inconsistency between status perceptions also leads to disliking, when individuals do not look up to those who they perceive to be admired by peers (frustration). Adolescents are not more likely to dislike those who they look up to (admiration). The results demonstrate the role of status perceptions on disliking tie formation.  相似文献

Our study examines the interactive effect of organizational status distance and geographical proximity on interpersonal professional tie formation. Whereas Blau (1977, 1994) proposes that geographical proximity will weaken the negative effect of organizational status distance on professional tie formation, our analysis of co-authorship in academic accounting over a 30-year period shows that geographical proximity between departments strengthens the negative effect of organizational status distance on the likelihood of coauthorship tie formation. These findings support our proposed “salience hypothesis”, which suggests that geographical proximity heightens the salience of organizational status boundary and consequently impedes people from status-distant organizations to form collaborative ties.  相似文献

While literature theorizing the relationship between socioeconomic status (SES), gender, and health outcomes is robust in high‐income countries, there is less scholarship examining how SES affects men and women in lower middle income countries (LMICs). Focusing on the LMIC case of Ghana, I use Wave 1 of the World Health Organization Study on Global Aging and Adult Health (SAGE) to examine the relationship between SES and diabetes among Ghanaian women and men. Specifically, I examine how key SES measures such as educational attainment, employment status, and income singly and collectively predict the odds of diabetes for Ghanaian men and women. I also examine the explanatory value of the reversal hypothesis, which posits that those of high SES experience higher rates of non‐communicable diseases. Overall, I find that while Ghanaian men experience increased odds of diabetes with increased education, Ghanaian women have higher odds of diabetes compared to men regardless of educational attainment. Understanding health patterns in LMICs like Ghana is important for sociological inquiry on health disparities seeking to incorporate more global perspectives.  相似文献

Abstract

Objective: The purpose of this study was to identify the health topics students received information about, how students obtained health-related information, and perceived believability of those sources. Participants and Methods: Students (N = 1202) were surveyed using the National College Health Assessment (NCHA) of the American College Health Association. Results: Nearly half (46%) of the sample reported not receiving any information, whereas only 0.5% received information on all health topics. The Internet was the most common source of health-related information, but, conversely, was perceived as the least believable source. Health center medical staff and university health educators were perceived to be the most believable sources. Conclusions: Future practice at the university setting should focus on delivering health information through believable messengers utilizing the most commonly reported sources of information. This may have implications towards how students shape their health-related social cognitions and subsequent behaviors.  相似文献

This study utilizes Los Angeles Family and Neighborhood Survey data to investigate children's (17 years and younger) health insurance coverage and routine medical and dental care visits by family immigration status (N = 2846). We use a combination of nativity (U.S. and foreign born) and legal status (authorized and unauthorized) of mothers and their children to categorize family immigration status (citizen mother-citizen child; authorized mother-citizen/authorized child; unauthorized mother-citizen/authorized child; unauthorized mother-unauthorized child). Health care use is measured by routine medical visits and dental visits. We find that health insurance coverage and dental visits are lowest for the children of unauthorized mothers but gaps are most pronounced for unauthorized mother–unauthorized child pairs. Policy implications, in light of recent health and immigration-related legislation, are discussed.  相似文献

As a specific art convention, graduating music students in college often invite network members to attend their degree recitals. This customary practice of network mobilization involves two types of tie effects that seemingly conflicted with each other, which became more acute when the practice abruptly changed during the Covid-19 pandemic. Based on invitation and attendance records collected from seventy-one recitals in a span of two decades before (N = 4866) and during the pandemic (N = 428) in Taiwan, multilevel analysis helped untangle which concert and tie features contributed to successful invitations at both the recital and invitation levels. Recruiting a larger proportion of weak ties helped boost the overall attendance at the recital level, while strong ties ensured positive responses to individual invitations in terms of both meeting at the recital hall and recalling the recital, particularly before the pandemic. More importantly, certain cross-level effects changed during the pandemic while others remained intact.  相似文献

Religiosity is associated with sexual behavior in adolescence; however, religiosity is a multidimensional construct, and it is not clear how different patterns of religiosity may differentially predict sexual behaviors and romantic relationships. We apply latent class analysis to nationally representative data from the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 10,149) to examine (1) what religiosity profiles exist among adolescents and (2) how they predict sexual behavior and romantic relationship status in adolescence and young adulthood. Religiosity in multiple domains was associated with lesser odds of sexual behavior compared to profiles marked by only affiliation, private, or public religiosity. Findings suggest that examining multiple facets of religiosity together is important for understanding how religiosity is associated with sexual behavior.  相似文献

A central part of relational ties between social actors is constituted by shared affiliations and events. The action of joint participation reinforces personal ties between social actors as well as mutually shared values and norms that in turn perpetuate the patterns of social action that define groups. Therefore the study of bipartite networks is central to social science. Furthermore, the dynamics of these processes suggests that bipartite networks should not be considered static structures but rather be studied over time. In order to model the evolution of bipartite networks empirically we introduce a class of models and a Bayesian inference scheme that extends previous stochastic actor-oriented models for unimodal graphs. Contemporary research on interlocking directorates provides an area of research in which it seems reasonable to apply the model. Specifically, we address the question of how tie formation, i.e. director recruitment, contributes to the structural properties of the interlocking directorate network. For boards of directors on the Stockholm stock exchange we propose that a prolific mechanism in tie formation is that of peer referral. The results indicate that such a mechanism is present, generating multiple interlocks between boards.  相似文献

This paper explores the impact of communication media and the Internet on connectivity between people. Results from a series of social network studies of media use are used as background for exploration of these impacts. These studies explored the use of all available media among members of an academic research group and among distance learners. Asking about media use as well as about the strength of the tie between communicating pairs revealed that those more strongly tied used more media to communicate than weak ties, and that media use within groups conformed to a unidimensional scale, showing a configuration of different tiers of media use supporting social networks of different ties strengths. These results lead to a number of implications regarding media and Internet connectivity, including: how media use can be added to characteristics of social network ties; how introducing a medium can create latent tie connectivity among group members that provides the technical means for activating weak ties, and also how a change in a medium can disrupt existing weak tie networks; how the tiers of media use also suggest that certain media support different kinds of information flow; and the importance of organization-level decisions about what media to provide and promote. The paper concludes with a discussion of implications for Internet effects.  相似文献

Measures that estimate the clustering coefficients of ego and overall social networks are important to social network studies. Existing measures differ in how they define and estimate triplet clustering with implications for how network theoretic properties are reflected. In this paper, we propose a novel definition of triplet clustering for weighted and undirected social networks that explicitly considers the relative strength of the tie connecting the two alters of the ego in the triplet. We argue that our proposed definition better reflects theorized effects of the important third tie in the social network literature. We also develop new methods for estimating triplet, local and global clustering. Three different types of mathematical means, i.e. arithmetic, geometric, and quadratic, are used to reflect alternative theoretical assumptions concerning the marginal effect of tie substitution.  相似文献

This article uses ethnographic methods to explore how peer support and community involvement influence the mental health and well-being of transgender (or, trans) people in the southeastern United States. The study builds on existing research that suggests that trans community involvement and peer support among trans people enhance mental health experiences and moderate the effects of stigma and discrimination on health outcomes. Through qualitative analysis of 158 hours of participant observation and 33 in-depth interviews with members of a trans community organization in the U.S. Southeast, this paper identifies three key processes through which peer support and community involvement enhance the mental health and well-being of trans people: (1) the normalization of trans identities and experiences; (2) the creation of a social support network; and (3) the empowerment of trans people.  相似文献

U.S. immigrants are a physically healthy population, but we do not understand the explanatory factors responsible for their physical health status, particularly those related to social network support. Using data from the 2001 wave of the National Health Interview Survey, we examine multiple measures of immigrant adaptation, investigating their influence on measures of physical health. In particular, we examine how well indicators of social support and integration explain the immigrant health advantage. Results show clear evidence of an immigrant paradox in physical health, but that measures of support and integration explain almost none of the immigration effect on physical health.  相似文献

The study aims were to compare maltreated and comparison adolescents' health problems and to identify how individual, family and home characteristics and maltreatment status affect adolescents' self-report of health status and health care use. The sample was 224 maltreated adolescents (mean age = 18.3 years) and 128 comparison adolescents (mean age = 18.15 years). Comparison adolescents reported more cold and pain symptoms during the previous 30 days but no differences in other physical health problems, self-assessment of their physical and mental health or health care use compared to maltreated adolescents. Girls were more likely to have had a dental checkup, to have seen a psychological counselor, and to self-identify their physical health as poor compared to boys. Older adolescents were less likely to have had a medical checkup or seen a psychological counselor than younger adolescents. A history of maltreatment was not related to health or health care disparities for adolescents growing up in the same low-income environment as adolescents without a maltreatment report. The environmental context and geographical location in which these adolescents grew up may be the primary driver in their health behaviors and health problems and not the experience of maltreatment.  相似文献

The purpose of this article is to overview the context of the mental health service in which we work, and family therapy's status prior to and after the impact of changes wrought by the introduction of the National Mental Health Policy. We then explore some key issues that we think contribute to the persistence of the occlusion of family therapy in child psychiatric services; and the strategies that we developed and are continuing to develop to support change. Finally, we describe the use of a family assessment instrument that we believe is central to our change strategy.  相似文献
