Although previous research on adolescents finds a link between early abuse and later victimization, the majority of this research is cross-sectional and based on samples of currently homeless adolescents. Therefore, factors that predict the likelihood of victimization have not been systematically examined. As such, the current study longitudinally examines the effects of early abuse and poor parenting on victimization via running away, delinquency, and early sexual onset among a sample of over 700 currently housed high-risk adolescents. Results revealed that having experienced sexual and physical abuse, as well as lower levels of parental monitoring and closeness, significantly predicted running away at wave 1. Adolescents who had run at wave 1 were significantly more likely to run again, more likely to engage in delinquency, and more likely to have had an early sexual onset at wave 3, all of which significantly predicted victimization at wave 4.  相似文献

We study the effect of perceptions in comparison with more objective measures of risk on individuals’ decisions to decline or accept risk reducing interventions such as flu shots, mammograms, and aspirin for the prevention of heart disease. In particular, we elicit individuals’ subjective probabilities of risk, with and without the interventions, and compare these perceptions to individually predicted risk based on epidemiological models. Respondents, especially women, appear to be aware of some of the qualitative relationships between risk factors and probabilities. However, on average they have very poor perceptions of the absolute probability levels as reported in the epidemiological literature. Perceptions of the level of risk are less accurate if a respondent is female and has poor numeracy skills. We find that perceived probabilities significantly affect the subsequent take-up rate of flu shots, mammograms, and aspirin, even after controlling for individually predicted risk using epidemiological models.  相似文献

The purpose of this study was to determine the feasibility and effectiveness of an on-site physical activity (PA) program offered with congregate meals. Study 1 surveyed meal-site users on their likelihood to participate. Study 2 used meal-site-manager interviews and site visits to determine organizational feasibility. Study 3, a controlled pilot study, randomized meal sites to a 12-week group-based social-cognitive (GBSC) intervention or a standard-care control. Studies 1 and 2 indicated that most meal-site users would participate in an on-site PA program, and meal sites had well-suited physical resources and strong organizational support for this type of program. In Study 3, GBSC participants increased their weekly PA over those in the control condition (p < .05, ES = .79). Results indicated that changes in task cohesion might have mediated intervention effectiveness. These studies demonstrate that a PA program offered in this venue is feasible, is effective in promoting PA, and could have a strong public health impact.  相似文献

Although a number of studies have investigated the consequences of leader-member similarity in the United States, there has been a dearth of research on its effects in other countries. Using a sample of 135 Mexican workers and their managers, this study assessed the effects of leader-member demographic similarity on members' organizational attachment (absence and organizational commitment) in a North Mexican manufacturing facility. Results showed that leader-member gender similarity was negatively associated with absence, and this effect was stronger for dyads with female leaders than for dyads with male leaders. Age similarity had mixed effects on attachment. While it had a negative association with absence (an indicator of lack of attachment), it also had a negative association with organizational commitment (an indicator of attachment). These findings are interpreted in the context of social psychological phenomena and elements of Mexican culture.  相似文献

Traditional leadership practice frameworks to guide systems change often fall short in today's practice environment. Reclaiming Futures is a national initiative to create an integrated, comprehensive, seamless system of care for teens with substance abuse problems involved in juvenile justice. It uses leadership and systems reform strategies to improve public health institutions. The premise is that interruption of the destructive cycle of drugs and delinquency can only be attained through the cultivation of shared strategic leadership. This article presents the limitations of traditional practice frameworks of leadership, describes the theory of this new approach to leadership development, and clarifies collaborative leadership and system change. The article includes an example of the framework in action, a discussion of lessons learned, and recommendations for community leadership development initiatives.  相似文献

These essays were originally presented at a symposium of the same title that took place at the annual meeting of the American Association of the Advancement of Slavic Studies in Toronto on November 20, 2003. The charge to the participants was to to reread the book and make short presentations on it, its significance, the validity of its analysis in hindsight, its historical contribution to our understanding of late communism, its influence on others. The symposium was timed to commemorate the thirtieth anniversary of writing of the book in 1973–1974 as well as the twenty-fifth anniversary of its publication in English in 1979.  相似文献

Crime is a significant and complex social issue with profound health consequences for individuals, families, and communities. Conceptualizing criminal behaviors as health behaviors reflects the potential for innovative interdisciplinary approaches and alliances to interrupt cycles of crime as a way to improve health. Incarcerated populations have extremely high rates of undiagnosed and undertreated infectious diseases and mental illnesses. Nursing is uniquely positioned to develop prevention, intervention, and treatment strategies for individuals involved in criminal activities before, during, and after incarceration.  相似文献

The purpose of this article is to determine whether known cardiac risk factors are more prevalent among women veterans who report having sustained sexual assault while in the military. We surveyed a random sample of 3,632 women veterans using Veterans Administration (VA) ambulatory care nationally. Obesity, smoking, problem alcohol use, sedentary lifestyle, and hysterectomy before age 40 were found to be more common in women reporting a history of sexual assault while in the military than in women without such history. An association between myocardial infarction and prior sexual assault history may be mediated in part by known cardiac risk factors.  相似文献
