Perceived group cohesion versus actual social structure: A study using social network analysis of egocentric Facebook networks

Research on group cohesion often relies on individual perceptions, which may not reflect the actual social structure of groups. This study draws on social network theory to examine the relationship between observable structural group characteristics and individual perceptions of group cohesion. Leveraging Facebook data, we extracted and partitioned the social networks of 109 participants into groups using a modularity algorithm. We then surveyed perceptions of cohesion, and computed group density and size using social network analysis. Out of six linear mixed effects models specified, a random intercept and fixed slope model with group size as a predictor of perceived group cohesion emerged as best fitting. Whereas group density was not linked to perceived cohesion, size had a small negative effect on perceived cohesion, suggesting that people perceive smaller groups as more cohesive. We discuss the potential of social network analysis, visualization tools, and Facebook data for advancing research on groups.     

Religion as resource: Religion and immigrant economic incorporation

Much of the immigration literature in the United States points toward a positive association between religious activity and immigrant economic adaptation. Immigrant congregations serve as informal job fairs, build social capital for entrepreneurial activity, and provide a locale for leadership skill development. Using the New Immigrant Survey, this hypothesis of religion as economic resource is tested among immigrants receiving permanent residency within the United States in 2003. Somewhat surprisingly, most findings indicate a null relationship between religion and economic outcomes (i.e. employment, occupation status, and earnings). However, in instances where a significant relationship does exist, non-Protestant immigrants suffer the greatest economic penalty, particularly among non-Protestants who are not regularly participating in a religious organization. In contrast, non-Protestants who regularly participate have a higher likelihood of employment and higher earnings than their non-participating counterparts. Therefore, this paper extends previous literature in specifying that the religion as resource hypothesis operates best for non-Protestant immigrants who are actively involved in their religious organizations.     

Gender and venture capital decision-making: The effects of technical background and social capital on entrepreneurial evaluations

Research on gender and workplace decision-making tends to address either supply-side disparities between men’s and women’s human and social capital, or demand-side differences in the status expectations of women and men workers. In addition, this work often relies on causal inferences drawn from empirical data collected on worker characteristics and their workplace outcomes. In this study, we demonstrate how tangible education and work history credentials – typically associated with supply-side characteristics – work in tandem with cultural beliefs about gender to influence the evaluative process that underlies venture capital decisions made in high-growth, high-tech entrepreneurship. Using an experimental design, we simulate funding decisions by venture capitalists (VCs) for men and women entrepreneurs that differ in technical background and the presence of important social ties. We demonstrate the presence of two distinct aspects of VCs’ evaluation: that of the venture and that of the entrepreneur, and find that the gender of the entrepreneur influences evaluations most when the person, rather than the venture, is the target of evaluation. Technical background qualifications moderate the influence of gendered expectations, and women receive more of a payoff than men from having a close contact to the evaluating VC. We discuss the implications for future research on gender and work.     

The effect of informal caregiving on social capital investments

Social capital is a resource derived from a person's social network and is important for various outcomes. Social capital declines over time and requires investments to avoid further declines or to increase the stock. However, certain life events can negatively affect social capital. This paper analyzes how informal caregiving, defined as unpaid assistance to persons who cannot perform the usual activities of daily living without help, affects social capital investments. Drawing on the German Socio-Economic Panel (GSOEP) with data for 15 years, I apply fixed-effects (FE) regressions to estimate the effect of changing caregiving status (extensive margin) and the effect of an additional hour of caregiving (intensive margin) on social capital investments. The results show that caregiving negatively affects investments in social capital for weak and strong ties unrelated to the care task. Furthermore, caregiving increases investments in strong ties that are care related.     

The burdens of social capital: How socially-involved people dealt with stress after Hurricane Katrina

Research shows that those with greater social capital enjoy better physical and mental health. The current study illuminates a paradox of social capital which may afflict those involved in traumatic events. Several years of survey data reveal a dynamic picture of the link between social capital and stress following Hurricane Katrina. Results reveal that initially after Katrina, those who were more socially embedded carried the greatest load with respect to helping the displaced population, thus experiencing more stress. But over time, the most socially-involved then snapped back from their stressful experiences more rapidly than isolates. This confirms that over the course of stressful events, social involvement first exposes people to more stress, but as time passes, provides them a significant buffer against negative psychosocial experiences.     

Partner selection and social capital in the status attainment process

Why is individual success so strongly affected by parental socioeconomic status? We argue that parental socioeconomic status affects the socioeconomic status of one's romantic partner, thereby partially determining one's own social capital and socioeconomic status. Censored-inflated structural equation models using data from the NEtherlands Longitudinal Lifecourse Study (NELLS) and British Household Panel Survey (BHPS) confirm these relationships, while cross-lagged analyses suggest that they may be causal in nature. The strong tendency for people to have a romantic partner that reflects their socioeconomic origin shows how far the influence of the parental home stretches and why it does so.

Latent Class Models in action: Bridging social capital & Internet usage

This paper explores how Latent Class Models (LCM) can be applied in social research, when the basic assumptions of regression models cannot be validated. We examine the usefulness of this method with data collected from a study on the relationship between bridging social capital and the Internet. Social capital is defined here as the resources that are potentially available in one’s social ties. Bridging is a dimension of social capital, usually related to weak ties (acquaintances), and a source of instrumental resources such as information. The study surveyed a stratified random sample of 417 inhabitants of Lisbon, Portugal. We used LCM to create the variable bridging social capital, but also to estimate the relationship between bridging social capital and Internet usage when we encountered convergence problems with the logistic regression analysis. We conclude by showing a positive relationship between bridging and Internet usage, and by discussing the potential of LCM for social science research.     

The bright side of migration: Hedonic,psychological, and social well-being in immigrants in Spain

The aim of this study was to examine the multi-dimensional structure of well-being in immigrant population, as well as to explore the complexity of well-being disparities between immigrants and host nationals. We analyzed hedonic, psychological, and social well-being in a sample of 1250 immigrants from Bolivia, Colombia, Morocco, Romania and Sub-Saharan Africa, together with that of 500 matched host nationals from Spain. Participants were selected by means of probability sampling with stratification by age and sex. Confirmatory factor analyses revealed that the re-specified tripartite model of well-being, including hedonic, psychological, and social components of the individual’s functioning, was the best fitting model, as compared to alternative models. Importantly, after adjustment for perceived friendship and support, marital status, income, sex and age, immigrants presented higher levels of well-being than host nationals. Compared to host nationals, immigrants reported especially higher eudaimonic well-being: social contribution and actualization, personal growth, self-acceptance, and purpose in life, and lower levels of well-being only in terms of positive relations with others and negative affect. These results are discussed in the context of positive psychology.     

Cross-national variation in the social origins and religious consequences of religious non-affiliation

I argue that the social implications of religious non-affiliation vary across cultural contexts, leading to differences across nations in both who is likely to be unaffiliated and the religious consequences of such non-affiliation. I test these propositions by examining cross-national variation in associations with non-affiliation using multilevel models and cross-sectional survey data from almost 70,000 respondents in 52 nations. The results indicate that: 1) both individual characteristics (gender, age, and marital status) and nation-level attributes (GDP, communism, and regulation of religion) strongly predict religious non-affiliation; 2) differences in non-affiliation by individual-level attributes—women vs. men, old vs. young, and married vs. single—are greatest in nations with low levels of religious regulation and high levels of economic development; and 3) the effect of religious non-affiliation on religiosity varies considerably by the political and religious context, and to a lesser extent by the level of economic development in each nation. These results highlight cultural variation in what it means to be religiously unaffiliated.     

The economic benefits of volunteering and social class

A theory that the economic benefits of volunteering are contingent on social class (as defined by similarities in labour market situation) is tested using seven waves of longitudinal data from the British Household Panel Study gathered between 1996 and 2008 and fixed-effects models. Volunteering has a positive effect on earnings, but it is confined to people in professional and managerial occupations. Employees in white and blue collar jobs do not benefit. The study suggests that inconsistent results from previous studies might be due to failure to consider occupational heterogeneity among volunteers.

论中国公民社会的成长与社会资本的培育

公民社会与社会资本是20世纪90年代以来中国学者关注的热点问题。公民社会所倡导的文化价值理念——合作、信任、互惠等无不与社会资本理论相契合,公民社会是社会资本得到滋养和发展的温床。我国公民社会发育的不完善严重制约了社会资本的形成。因此需要大力培育我国的公民社会,形成政府与公民合作治理的局面,从而提升我国社会资本的存量。     

Political democracy,economic liberalization,and macro-sociological models of intergenerational mobility

Building on the previously investigated macro-sociological models which analyze the consequences of economic development, income inequality, and international migration on social mobility, this article studies the specific contextual covariates of intergenerational reproduction of occupational status in post-communist societies. It is theorized that social mobility is higher in societies with democratic political regimes and less liberalized economies. The outlined hypotheses are tested by using micro- and macro-level datasets for 21 post-communist societies which are fitted into multilevel mixed-effects linear regressions. The derived findings suggest that factors specific to transition societies, conventional macro-level variables, and the legacy of the Soviet Union explain variation in intergenerational social mobility, but the results vary depending which birth cohorts survey participants belong to and whether or not they stem from advantaged or disadvantaged social origins. These findings are robust to various alternative data, sample, and method specifications.     

The resilience of neighborhood social processes: A case study of the 2011 Brisbane flood

Social disorganization theories position neighborhood social capital and collective efficacy as key social processes that should facilitate community resilience in the aftermath of disaster. Yet limited evidence demonstrates that these social processes are themselves resilient with some studies showing that disaster can fracture even once cohesive neighborhoods. In this paper we assess the stability of neighborhood level collective efficacy and social capital before and after a disaster. We use multilevel structural equation modeling and draw on census and longitudinal survey data collected from over 4000 residents living in 148 neighborhoods in Brisbane, Australia before and after a significant flood event. We examine what happens to social capital and collective efficacy in flooded and non-flooded neighborhoods and assess whether demographic shifts are associated with change and/or stability in these processes. We find strong evidence that these processes operate similarly across flooded and not flooded communities. Our findings also reveal significant stability for our measures of social capital across time, while collective efficacy increases post flood across all neighborhoods, but more so in flooded neighborhoods. Neighborhood demographics have limited effect on patterns of stability or change in these social processes. We discuss the theoretical and practical implications of these findings for our understanding of neighborhood resilience in the wake of disaster.

社会资本理论视阈下的我国农村治安问题分析

近年来,我国农村治安形势不容乐观,主要表现在农民上访事件和群体性事件呈上升趋势,偷盗抢劫等刑事案件发案率居高不下,非法宗教活动屡禁不止等。从根源上说,这是社会转型期难以避免的,传统的农村熟人社会下所形成的人们之间的普遍信任、村规民约及相互交往和组织参与在市场经济大潮的冲击下已经淡化,而这些恰恰是作为社会稳定基础的农村社会资本的重要部分。因此,改善农村治安状况关键在于重构传统农村社会资本并积极培育和发展符合社会主义市场经济的新型农村社会资本。     

Explaining relationships between ethnic diversity and informal social capital across European countries and regions: Tests of constrict, conflict and contact theory

In this study we focus on the relationship between ethnic diversity and informal social capital. As this refers to rather strong social ties in the intimate domain, it is a strict test of Putnam’s claim that ethnic diversity would decrease social capital. In order to explain these relationships, we derived mediating mechanisms from conflict and contact theory. Using data from the European Social Survey (2002/2003), we applied multilevel analyses considering three levels: individuals, regions and countries. Our results revealed a direct positive effect of ethnic diversity at the country level on informal helping, yet no indirect effect via the mediating variables. At the regional level, we only found an indirect effect of ethnic diversity. Here, ethnic diversity increases the likelihood of intergroup contact that in turn is positively related to both informal social meeting and helping. Perceived ethnic threat turned out to have a negative effect on informal social meeting.     

School choice & social stratification: How intra-district transfers shift the racial/ethnic and economic composition of schools

The liberation model hypothesizes that school choice liberates students from underperforming schools by giving them the opportunity to seek academically superior schooling options outside of their neighborhoods. Subsequently, school choice is hypothesized to diminish stratification in schools. Data from one urban school district is analyzed to test these hypotheses. We specifically examine which factors influence the propensity for parents to participate in choice, and how school choice changes the racial/ethnic and economic composition of schools. We further examine how school choice influences similar changes within distinct sociogeographic areas within the district. We find that families who are zoned to more racially/ethnically and economically diverse schools in sociogeographically diverse areas are more likely to participate in school choice. We also find that intra-district choice is associated with a slight increase in social stratification throughout the district, with more substantial stratification occurring in the most demographically diverse areas and schools.
