The relationship between interpersonal trust and membership in voluntary associations is a persistent research finding in sociology. What is more, the notion of trust has become a central issue in current social science theorizing covering such diverse approaches as transaction costs economics or cognitive sociology. In different ways and for different purposes, these approaches address the role of voluntary organizations, although, as this paper argues, much of this thinking remains sketchy and underdeveloped. Against an empirical portrait of this relationship, the purpose of this paper is to assess such theorizing. We first set out to explicate major approaches to trust in economics, sociology and political science, using the non-profit or voluntary organization as a focal point. We then examine the various approaches in terms of their strengths and weaknesses, and, finally, identify key areas for theoretical development. In particular, we point to the social movement literature, the social psychology of trust, and recent thinking about civil society. 相似文献
Much has been done to identify psychosocial factors influencing risk of vocational injury and prolonged disability. The purpose of this paper is to enhance the ability of injured workers to return to their prior worker role through the identification of the influencing psychosocial perceptions. Psychosocial perceptions may assist in the identification of negative or counterproductive factors that hinder the rehabilitative process. Identifying perceptions are individual centered and focused on the views of injured workers as they proceed through the transition in life following injury. Occupational therapists play a key role in the rehabilitative process of injured workers through enhancing the person-job-environment fit [4]. 相似文献
A marginal regression approach for correlated censored survival data has become a widely used statistical method. Examples
of this approach in survival analysis include from the early work by Wei et al. (J Am Stat Assoc 84:1065–1073, 1989) to more
recent work by Spiekerman and Lin (J Am Stat Assoc 93:1164–1175, 1998). This approach is particularly useful if a covariate’s
population average effect is of primary interest and the correlation structure is not of interest or cannot be appropriately
specified due to lack of sufficient information. In this paper, we consider a semiparametric marginal proportional hazard
mixture cure model for clustered survival data with a surviving or “cure” fraction. Unlike the clustered data in previous
work, the latent binary cure statuses of patients in one cluster tend to be correlated in addition to the possible correlated
failure times among the patients in the cluster who are not cured. The complexity of specifying appropriate correlation structures
for the data becomes even worse if the potential correlation between cure statuses and the failure times in the cluster has
to be considered, and thus a marginal regression approach is particularly attractive. We formulate a semiparametric marginal
proportional hazards mixture cure model. Estimates are obtained using an EM algorithm and expressions for the variance–covariance
are derived using sandwich estimators. Simulation studies are conducted to assess finite sample properties of the proposed
model. The marginal model is applied to a multi-institutional study of local recurrences of tonsil cancer patients who received
radiation therapy. It reveals new findings that are not available from previous analyses of this study that ignored the potential
correlation between patients within the same institution. 相似文献
This study (1) assessed whether parent health mediated associations between exposures to the 2010 BP Deepwater Horizon oil spill (BP-DHOS) and child health, and whether child health mediated associations between BP-DHOS exposures and parent health; and (2) assessed bidirectional longitudinal associations between parent health and child health following the BP-DHOS. The study used three waves of panel data (2014, 2016, and 2018) from South Louisiana communities highly impacted by the BP-DHOS. Parents with children (aged 4–18 at the time of the interview) were interviewed based on a probability sample of households. Focal measures included economic and physical BP-DHOS exposures, self-reported parent health, and parent-reported child health. Health measures were gathered at three time points. The analyses included mediation analysis and estimating and comparing effect sizes of longitudinal cross-lagged effects between parent health and child health. Results showed that parent health partly mediated associations between BP-DHOS exposures and child health, and that child health partly mediated associations between BP-DHOS exposures and parent health. Paths from prior waves of parent health to subsequent waves of child health were positive and statistically significant as were paths from prior waves of child health to subsequent waves of parent health. The differences in size of the child-to-parent health effects and the parent-to-child health effects were not statistically significant. This study’s results extend evidence for the post-disaster effect of parent health on child health and the effects of child health on parent health. These findings support the contention that harm to the health of one’s family member following disasters operates as a form of resource loss deleterious to one’s health.
This study evaluated the impact of housing services among child welfare-involved families using observational data. Propensity score matching with data from the National Survey of Child and Adolescent Well-Being compared intact families (n = 183) who received housing services 12 months after initial investigation to nontreated families balanced on characteristics at the time of investigation. Results suggested that general housing services failed, on average, to effectively address the needs of inadequately housed families. 相似文献
Objective: The objective of this study was to investigate whether misaligned or uncertain ambitions in adolescence influence the process of socioeconomic attainment. Methods: Using 34 years of longitudinal data from the British Cohort Study (BCS70), we considered whether youth with (1) misaligned ambitions (i.e., those who either over- or underestimate the level of education required for their desired occupation), (2) both low occupational aspirations and educational expectations (low-aligned ambitions), and (3) uncertainty with regard to their future occupations (uncertain ambitions) at age 16 experienced more unemployment spells, lower educational attainment, and lower hourly wages in adulthood compared to youth with high occupational aspirations and educational expectations (high-aligned ambitions). Results: Youth who hold misaligned or uncertain aspirations show long-term deficits in employment stability and educational attainment, which in turn leads to lower wage attainments at age 34. Conclusion: Misaligned and uncertain ambitions in adolescence compromise the construction of life paths and the realization of long-term educational and occupational goals. 相似文献
To what extent does community context influence individuals’ proclivity to participate in community‐oriented activities and projects? In this article we utilize survey data from residents of 99 Iowa communities to conduct a multilevel analysis of voluntary participation and community action, simultaneously addressing voluntary participation at the individual level and “community action” at the community level. Additionally, we test the suggestion that community attachment may constitute a unique form of social capital. The robustness of these data allows us to overcome the obstacles that have led to the conflation of individual‐ and community‐level attributes in many community studies. We show that community attachment and community‐oriented action are determined almost entirely by individuals’ characteristics rather than by the characteristics of communities, and thus do not constitute community‐level phenomena, calling into question the assumptions on which certain theoretical approaches to community are based. 相似文献
