It is commonly suggested that social housing is allocated on the basis of 'need'. The authors, however, suggest that the concept of risk provides a much better explanation of the complex interplay of interests involved in the allocation process. In particular, risk explains developing allocation methods in low-demand areas. The thesis is exemplified by drawing upon data derived from the authors' original research on the rehousing of sex offenders.  相似文献

Since the early 1970s, the major American parties have moved from general consensus on women's rights issues to sharp polarization. While previous efforts to explain this realignment have identified pieces of the puzzle, these explanations have been generally incomplete and atheoretical. I argue that party positions are determined by the perceived value of specific issue positions for maintaining and expanding the party's coalition of electoral support. Thus, changes in both the composition of the party's coalition and the way the issue is defined and understood can bring about changes in the issue positions adopted by parties. Using the Convention Delegate Studies (1972–1992), this research suggests that both replacement (coalition change) and in the case of Democrats, conversion (caused by issue change) have been important mechanisms for bringing about party realignment on women's rights. This explanation both encompasses causal factors highlighted by previous scholars and points to other important contributing causes.  相似文献

Alcohol use is cited as a risk factor for exposure to HIV infection through risky sexual behavior, especially among adolescents. From Social Cognitive Theory, positive outcome expectancies about the use of alcohol have often been presented as a critical aspect of alcohol use. Yet little is known about how they might be related to different aspects of HIV risk. Using latent growth curve modeling with data from 292 American Indian youth across seven years, both alcohol use and positive expectancies increased significantly; a lower-risk group showed significantly slower increases in both. Changes in alcohol use and outcome expectancies were significantly interrelated, providing support for reciprocal influence between the two constructs. Positive alcohol outcome expectancies may provide a preventive intervention point worthy of further consideration as influencing alcohol use and lowering HIV sexual risk among adolescents.Associate Professor at the University of Colorado at Denver and Health Sciences Center.

Accumulating evidence suggests that African American men and women experience unique challenges in developing and maintaining stable, satisfying romantic relationships. Extant studies have linked relationship quality among African American couples to contemporaneous risk factors such as economic hardship and racial discrimination. Little research, however, has examined the contextual and intrapersonal processes in late childhood and adolescence that influence romantic relationship health among African American adults. We investigated competence-promoting parenting practices and exposure to community-related stressors in late childhood, and negative relational schemas in adolescence, as predictors of young adult romantic relationship health. Participants were 318 African American young adults (59.4 % female) who had provided data at four time points from ages 10–22 years. Structural equation modeling indicated that exposure to community-related stressors and low levels of competence-promoting parenting contributed to negative relational schemas, which were proximal predictors of young adult relationship health. Relational schemas mediated the associations of competence-promoting parenting practices and exposure to community stressors in late childhood with romantic relationship health during young adulthood. Results suggest that enhancing caregiving practices, limiting youths’ exposure to community stressors, and modifying relational schemas are important processes to be targeted for interventions designed to enhance African American adults’ romantic relationships.  相似文献

Substance use often begins earlier among American Indians compared to the rest of the United States, a troubling reality that puts Native youth at risk for escalating and problematic use. We need to understand more fully patterns of emergent substance use among young American Indian adolescents, risk factors associated with escalating use trajectories, and protective factors that can be parlayed into robust prevention strategies. We used growth mixture modeling with longitudinal data from middle-school students on a Northern Plains reservation (Wave 1 N = 381, M age at baseline = 12.77, 45.6 % female) to identify subgroups exhibiting different trajectories of cigarette, alcohol, and marijuana use. We explored how both risk (e.g., exposure to stressful events, deviant peers) and protective (e.g., positive parent–child relationships, cultural identity) factors were related to these trajectories. For all substances, most youth showed trajectories characterized by low rates of substance use (nonuser classes), but many also showed patterns characterized by high and/or escalating use. Across substances, exposure to stress, early puberty, and deviant peer relationships were associated with the more problematic patterns, while strong relationships with parents and prosocial peers were associated with nonuser classes. Our measures of emergent cultural identity were generally unrelated to substance use trajectory classes among these young adolescents. The findings point to the importance of early substance use prevention programs for American Indian youth that attenuate the impact of exposure to stressful events, redirect peer relationships, and foster positive parent influences. They also point to the need to explore more fully how cultural influences can be captured.  相似文献
