Influences and Mediators of the Effect of Poverty on Young Adolescent Depressive Symptoms 总被引:2,自引:0,他引:2
Data from a sample of young adolescents between the ages of 10 and 12 years (N = 898) from the mother–child data set of the National Longitudinal Survey of Youth were analyzed in a study of influences that explain the relation between poverty and depressive symptoms measured 2 years later. Other variables that predicted youth depressive symptoms were also identified. Results indicated that neighborhood problems, nonparticipation in outside school and neighborhood activities, residing with mothers who exhibited depressive symptoms, and mother's use of physical punishment were partial mediators of the effect of poverty on depressive symptoms 2 years later. Youth health status, lower levels of school satisfaction, marital-partner conflict, and father's emotional support also predicted depressive symptoms. The findings indicate that youth depressive symptoms are multiply determined and that poverty can adversely affect young adolescents in many ways. 相似文献

Our purpose is to provide empirical evidence of the relations between the quality of governmental audit services and auditor tenure and between quality and fixed fee audit contracts. Audit quality is assessed by Offices of Regional Inspectors General and is based on a review of the audit reports and supporting working papers. We test a model of quality supplied on a sample of audit engagements selected from a population of audited federal assistance programs. The empirical analysis finds that the probability of receiving a substandard audit increases with the length of the auditor-client relationship. Our analysis finds a positive relation between fixed fee contracts and the incidence of violations of professional standards among audits of federal assistance programs. Additionally, we provide evidence that the incidence of noncom-pliance with professional standards is significantly lower when the audit contract contains a provision for administrative and/or legal remedies in the event of substandard performance. 相似文献

This paper develops the concept of institutional social capital and discusses its importance in the labor market. Institutional social capital is constituted by the resources inherent in an organization (such as a school) and thereby available to members of that organization. This is contrasted with the social capital available to individuals through their own personal networks. In the labor market context, an example of institutional social capital is the ties that schools have with employers who recruit a proportion of their new employees as they prepare to graduate. The paper examines how these ties and the norms governing the important labor market screening role played by the high school developed in post-WWII Japan. I also discuss an important positive externality – social control over students – generated by schools institutional social capital. Finally, I examine current challenges to Japanese high schools institutional social capital. 相似文献

The article describes a study of the perceptions of three groups--patients, orthopaedic surgeons and the surgeons' practice managers--concerning three types of legal risk associated with the duty of care: failure to follow up, failure to warn and failure to diagnose. The study found there is cause for concern about doctors' follow-up and documentation of patient care. Doctors may be unaware of the Australian courts' propensity to emphasise practitioner responsibility rather than patient autonomy. A further important result is the considerable disparity between the surgeons' views and the views of their practice managers about the duty of care. The article draws out implications for improved risk awareness and suggests further research. 相似文献
