We develop further our model of affirmative action as help (Pratkanis & Turner, 1996b; Turner & Pratkanis, 1994) by looking at the impact of aid on the donor. White Americans often take one of three approaches toaffirmative action. First, they can reject affirmative action because of their own personal frustrations. Second, they can engage in selective aid that maintains the basic patterns of social dominance. Both of these approaches can damage the psychological functioning of Whites. Third, White Americans can proactively seek to remove discriminatory barriers in a process we call democratic altruism, thereby opening the possibility of learning from diverse others and growth as a person. We conclude by discussing tactics for promoting democratic altruism.  相似文献

College students with and without disabilities (N = 121) completed measures of career decision-making self-efficacy (N. E. Betz, K. Klein, & K. M. Taylor, 1996) and career decision-making attributional style (D. A. Luzzo & A. Jenkins-Smith, 1998). Students with disabilities reported significantly lower levels of career decision-making self-efficacy and exhibited more of a pessimistic attributional style for career decision making than did their peers without disabilities. Results are discussed in the context of developing effective career counseling interventions for college students with disabilities.  相似文献

Family-based follow-up study designs are important in epidemiology as they enable investigations of disease aggregation within families. Such studies are subject to methodological complications since data may include multiple endpoints as well as intra-family correlation. The methods herein are developed for the analysis of age of onset with multiple disease types for family-based follow-up studies. The proposed model expresses the marginalized frailty model in terms of the subdistribution hazards (SDH). As with Pipper and Martinussen’s (Scand J Stat 30:509–521, 2003) model, the proposed multivariate SDH model yields marginal interpretations of the regression coefficients while allowing the correlation structure to be specified by a frailty term. Further, the proposed model allows for a direct investigation of the covariate effects on the cumulative incidence function since the SDH is modeled rather than the cause specific hazard. A simulation study suggests that the proposed model generally offers improved performance in terms of bias and efficiency when a sufficient number of events is observed. The proposed model also offers type I error rates close to nominal. The method is applied to a family-based study of breast cancer when death in absence of breast cancer is considered a competing risk.  相似文献

Despite strong indications of elevated risk of suicidal behavior in lesbian, gay, bisexual, and transgender people, limited attention has been given to research, interventions or suicide prevention programs targeting these populations. This article is a culmination of a three-year effort by an expert panel to address the need for better understanding of suicidal behavior and suicide risk in sexual minority populations, and stimulate the development of needed prevention strategies, interventions and policy changes. This article summarizes existing research findings, and makes recommendations for addressing knowledge gaps and applying current knowledge to relevant areas of suicide prevention practice.  相似文献

A central concern over global value chains (GVCs) is whether the integration of national firms into GVCs exacerbates income inequality within countries. However, despite decades of research, the distributional consequences of GVCs remain unclear in the empirical literature. Drawing on panel data from 96 countries between 1980 and 2013, we examine the effects of GVC integration on market income inequality and whether national labour regulations moderate these effects. We find integration increases inequality in the global North and South. More importantly, we find labour regulations amplify the inequality effects of integration in Southern countries by expanding the size of the informal sector while suppressing these effects in Northern countries by promoting unionization. This suggests institutional power from national labour regulations may enhance the bargaining power of labour in the North through increasing collective resources while disempowering labour in the South through reinforcing labour market segmentation between formal and informal sectors.  相似文献
