Say Yes First--To Rural Youth and Family Alcohol/Drug Prevention (SYF) was a 5-year, federally-funded U.S.D.H.H.S. Center for Substance Abuse Prevention (CSAP) project that involved 859 children in the class of the year 2000. The children in four rural school districts were followed from Grade 4 to Grade 8 from 1991 to 1996. Initial results in a previous publication showed significant lower drug usage in this cohort than comparison students. A follow-up of 120 SYF participants and 136 comparison students in high schools using the National Youth Survey (Follow Up Questionnaire) indicated lower usage of alcohol, tobacco and other drugs for the program students and lower lifetime prevalence of marijuana use for program vs. comparison students. SYF students had higher course grades, lower school absenteeism, more positive attitudes toward school, less trouble in school and less negative self-appraisal. Program students also reported greater participation in sports, more family communication and fewer disagreements or arguments with their parents. 相似文献

Though often conflated, informal physical exercise and organized athletic participation have very different implications for adolescent sexual risk outcomes. The purpose of this research is to disaggregate strenuous exercise from sports, examine how each is associated with sexual risk, and explain the observed differences using the conceptual lens of cultural resource theory. Using a nationally representative sample of over 16,000 public and private high school students, we employ logistic regression to test hypotheses about the gender-specific and race-specific effects of strenuous exercise and athletic participation on adolescent sexual risk behavior. The results show that both forms of physical activity buffer sexual risk for girls. Strenuous exercise is associated with increased odds of sexual risk for boys. Sports and race interact to influence boys' sexual risk outcomes: Athletic participation is associated with lowered odds of sexual risk for white male adolescents, but heightened odds of sexual risk for black male adolescents. 相似文献

This article provides a national estimate of wife rape and various other types of sexual coercion by a spouse or intimate partner. Findings from a 1997 national probability sample revealed that 34% of women were victims of some type of sexual coercion with a husband or partner in their lifetime. Of these women, 10% experienced rape by a current partner. This rate increased to 13% when only victims of rape by a current husband were included, which is consistent with previous studies on wife rape. Other findings reveal that women had unwanted sex with a current spouse or partner in return for a partner's spending money on them (24%), because they thought it was their "duty" (43%), after a romantic situation (29%), after the partner begged and pleaded with them (26%), and after their partner said things to bully them (9%). The importance of examining a continuum of sexual coercion is discussed and findings are compared and contrasted with other prevalence rates for sexual coercion in marriage. 相似文献

This review of the family literature on domestic violence suggests that two broad themes of the 1990s provide the most promising directions for the future. The first is the importance of distinctions among types or contexts of violence. Some distinctions are central to the theoretical and practical understanding of the nature of partner violence, others provide important contexts for developing more sensitive and comprehensive theories, and others may simply force us to question our tendency to generalize carelessly from one context to another. Second, issues of control, although most visible in the feminist literature that focuses on men using violence to control “their” women, also arise in other contexts, calling for more general analyses of the interplay of violence, power, and control in relationships. In addition to these two general themes, our review covers literature on coping with violence, the effects on victims and their children, and the social effects of partner violence.

Perceived Risks from Radiation and Nuclear Testing Near Semipalatinsk, Kazakhstan: A Comparison Between Physicians, Scientists, and the Public 总被引:2,自引:0,他引:2
Determining the difference in perception of risk between experts, or more educated professionals, and laypeople is important so that a potential hazard can be effectively communicated to the public. Many surveys have been conducted to better understand the difference between expert and public opinions, and often laypeople exhibit higher perceptions of risk to hazards in comparison to experts. This is especially true when health risk is due to radiation, nuclear power, and nuclear waste. This article focuses on one section of a risk perception survey given to two groups of individuals with a more specialized education (scientists and physicians) and laypeople (villagers) in the Semipalatinsk region of Kazakhstan. All of these groups live near the former Soviet nuclear test site. Originally, it was expected that the scientists and physicians would have similar perceptions of radiation risk, while the public perceptions would be higher, but this was not always the case. For example, when perceptions of risk pertain to the health impacts of nuclear testing or the dose-response nature of radiation exposure, the physicians tend to agree with the laypeople, not the scientists. The villagers are always the most risk-averse group, followed by the physicians and then the scientists. These differences are likely due to different frames of reference for each of the populations. 相似文献

Distribution-free confidence bands for a distribution function are typically obtained by inverting a distribution-free hypothesis test. We propose an alternate strategy in which the upper and lower bounds of the confidence band are chosen to minimize a narrowness criterion. We derive necessary and sufficient conditions for optimality with respect to such a criterion, and we use these conditions to construct an algorithm for finding optimal bands. We also derive uniqueness results, with the Brunn–Minkowski Inequality from the theory of convex bodies playing a key role in this work. We illustrate the optimal confidence bands using some galaxy velocity data, and we also show that the optimal bands compare favorably to other bands both in terms of power and in terms of area enclosed. 相似文献
