Social capital is a central concept in social science research, and it is measured in diverse ways. Few measurement approaches take the network structure of complex institutional settings into account. In this study, using data from a large-scale school-based randomized field trial, we develop several factor analytic models to test the validity and reliability of a new survey battery capturing multiple dimensions of social capital in such settings. We demonstrate that it is important to account for institutional and network structure in social capital measures, and we show how social capital can be operationalized as the shared variance between different relational characteristics in complex settings with multiple subnetworks.  相似文献

Girls who experience father absence in childhood also experience accelerated reproductive development in comparison with peers with present fathers. One hypothesis advanced to explain this empirical pattern is genetic confounding, wherein gene-environment correlation (rGE) causes a spurious relationship between father absence and reproductive timing. We test this hypothesis by constructing polygenic scores for age at menarche and first birth using recently available genome-wide association study results and molecular genetic data on a sample of non-Hispanic white females from the National Longitudinal Study of Adolescent to Adult Health. We find that young women’s accelerated menarche polygenic scores are unrelated to their exposure to father absence. In contrast, polygenic scores for earlier age at first birth tend to be higher in young women raised in homes with absent fathers. Nevertheless, father absence and the polygenic scores independently and additively predict reproductive timing. We find no evidence in support of the rGE hypothesis for accelerated menarche and only limited evidence in support of the rGE hypothesis for earlier age at first birth.  相似文献

Training social workers for leadership roles in electoral campaigns and political offices increases the profession’s effectiveness in promoting public policy that reflects our professional values and commitment to social justice. This research describes and evaluates an educational experience in the US that prepares social work practitioners and students to run for elected office; to work in leadership positions at the local, state, and federal levels; and serve as effective advocates for social change. Participants’ plans for future political engagement before and after the training were compared. Following the training, participants are more likely to plan to be politically active in general. Their intentions to work on campaigns, run for office, and engage with elected officials increased. These results can inform education in other social work settings.  相似文献

Although there is a growing amount of research on the role that faith-based organizations play in disaster recovery, there is currently no research that has investigated the influence that social capital has on individual disaster victims’ proclivity to rely on these organizations for recovery assistance. This current exploratory research sought to observe the relationship between individuals’ bonding social capital, in addition to other individual characteristics, and their perceived reliance on faith-based organizations for tangible disaster aid in future events using a national survey administrated by the Associated Press–NORC for Public Affairs Research in 2013. As a by-product of the analysis performed, it is observed that bonding social capital is related to an individual’s perceived reliance on faith-based organizations, whereas other demographic variables such as race are not.  相似文献

Using data from a cohort study of students at risk for high school dropout, we examined associations between violence exposure and past 30‐day alcohol and marijuana use. We used varying‐coefficient regression with person‐level fixed effects to estimate how those associations changed within‐person across ages approximately 14–23. Generally, violence perpetration was most strongly associated with substance use, within‐person. Substance use became increasingly associated with both observed violence and violence perpetration during early/middle adolescence; this increase continued longer into development (age 18+) for alcohol use. Across most of the age range studied here, violence victimization was minimally associated with within‐person changes in substance use. Results indicate age‐specific associations between violence exposure and alcohol and other drug use, which may be useful for informing prevention strategies.  相似文献

This paper reports how transit crime and perception of crime have been barriers to an area-focused and person-based ethnographic urban health and wellbeing research study in St. Louis. This study has experienced two primary challenges. First, respondent concerns about crime have impeded the ability of the study to follow best practices to strengthen ethnographic and qualitative research. Second, these concerns have impeded sampling and respondent participation in a way that decreases the voice and perspectives of older adults.  相似文献

This analysis of gambling habits of Canadian university students (ages 18–25) dovetails two recent developments in the field of gambling studies. First, the popularity of latent class analysis to identify heterogeneous classes of gambling patterns in different populations; second, the validation of the Gambling Motives Questionnaire (with financial motives) among university students—specifically to understand both how and why emerging adults gamble. Our results support a four-class model of gambling activity patterns, consisting of female-preponderant casual and chance-based gambling groups, and male-preponderant skill-based and extensive gambling groups. Each class shows a specific combination of motives, underscoring the necessity for nuanced responses to problem gambling among emerging adults. More specifically, gambling for the skill-based group appears primarily to be a source of thrill and a way to cope; for the chance-based group, gambling appears but one symptom of a set of wider issues involving depression, anxiety, substance use, and low self-esteem; while extensive gamblers seem to seek excitement, sociality, and coping, in that order. Only the chance-based group was significantly more likely than casual gamblers to be motivated by financial reasons. Situating our analysis in the literature, we suggest that interventions for the predominantly male subtypes should address gambling directly (e.g. re-focusing excitement seeking into other activities, instilling more productive coping mechanisms) while interventions for predominantly female subtypes should address low self-esteem in conjunction with depression, substance abuse, and problematic levels of gambling. We conclude future research should focus on links between self-esteem, depression, substance abuse, and financial motives for gambling among female emerging adults.  相似文献

This study examines whether there are multiple joint trajectories of depression and problem gambling co-development in a sample of emerging adults. Data were from the Manitoba Longitudinal Study of Young Adults (n = 679), which was collected in 4 waves across 5 years (age 18–20 at baseline). Parallel process latent class growth modeling was used to identified 5 joint trajectory classes: low decreasing gambling, low increasing depression (81%); low stable gambling, moderate decreasing depression (9%); low stable gambling, high decreasing depression (5%); low stable gambling, moderate stable depression (3%); moderate stable problem gambling, no depression (2%). There was no evidence of reciprocal growth in problem gambling and depression in any of the joint classes. Multinomial logistic regression analyses of baseline risk and protective factors found that only neuroticism, escape-avoidance coping, and perceived level of family social support were significant predictors of joint trajectory class membership. Consistent with the pathways model framework, we observed that individuals in the problem gambling only class were more likely using gambling as a stable way to cope with negative emotions. Similarly, high levels of neuroticism and low levels of family support were associated with increased odds of being in a class with moderate to high levels of depressive symptoms (but low gambling problems). The results suggest that interventions for problem gambling and/or depression need to focus on promoting more adaptive coping skills among more “at-risk” young adults, and such interventions should be tailored in relation to specific subtypes of comorbid mental illness.  相似文献

As the largest minority group in the United States, Latinas/os have experienced a long history of discrimination, prejudice, and stigmatization as gang members. A contemporary survey of law enforcement agencies reported that Latinos continue to be the largest proportion of any racial or ethnic group involved in gangs. To describe such a pattern, the framework of settler colonialism will be utilized to describe differential experiences based on race, gender, and how structural inequalities vary by region and time. Latinas/os have been particularly impacted by segregation, second‐class treatment, and policies considered racially neutral. Gangs provide a topical area for examining patterns of racialization and social control. The authors of this article will outline the research literature on gangs and how settler colonialism has impacted the Latina/o population regarding the origination of gangs, reasons for joining, behaviors and activities, and the process for leaving these groups. The authors emphasize decolonization strategies including reducing structural inequalities and thereby reducing gang membership and risky behaviors. Until this can be accomplished, the authors hope for human rights, labor equity, and religious organizing efforts that can form into social movements of collective empowerment and justice.  相似文献
