This study examines demographic and situational factors in an effort to predict whether or not a complainant was injured, used resistance, experienced a completed assault, and whether charges were brought against the offender. If the accused had consumed alcohol or drugs, he was almost seven times more likely to be arrested. The complainant was six times more likely to report rape completion if she had consumed alcohol or drugs and if the complainant fell unconscious at any time during the attack she was significantly less likely to use a resistance strategy. The complainant's use of a compliance strategy at any time during the assault positively predicted not using a physical resistance strategy and sexual assault completion. The reporting of injury positively predicted use a physical resistance strategy and sexual assault completion. If the assault was completed, it was less likely that charges were pressed. Implications of these findings are discussed, and directions for future research are offered. 相似文献

Is it more effective to reduce poverty among the elderly by increasing the benefits paid by the Supplemental Security Income (SSI) program or by increasing eligibility for the program? This paper answers that question from a policymaker's perspective. At given program cost levels, we compare the potential reduction in poverty from increasing benefit levels to the potential reduction associated with a variety of policy proposals that would increase eligibility for the program. This paper employs a microsimulation model containing an eligibility and benefits calculator, a participation model, and an optimization algorithm. The data are from the Survey of Income and Program Participation supplemented by the administrative records of the SSI program. The results show that increasing eligibility by relaxing the restrictions of the means tests can be more effective in reducing poverty than raising benefit levels. 相似文献

Circumstantial evidence places the p66 isoform of the adapter protein Shc in a position to mediate the accelerated aging phenotype displayed by mice expressing shortened forms of the tumor suppressor protein p53. We present a model in which p66(shc) may be responsible for integrating signals from the p53 pathway with signals from the insulin-like growth factor-1/Daf pathway in mammals. A full understanding of how interactions between p53 and p66(shc) affect longevity will require the production of animals with mutations in the genes encoding both proteins. 相似文献

NEW YORK CITY--Everyone has slow-witted moments: entering a room only to forget why, putting ice cream into the fridge, or blanking out on how to use the microwave. Some clinicians think that periodic mental lapses might help diagnose dementia with Lewy bodies (DLB), a scourge that kills brain cells (see DLB Case Study), although not all experts agree. Now, scientists have found that some cognitive blunders crop up more frequently in patients with DLB than in those with Alzheimer's disease (AD) or in healthy elderly individuals, according to work presented here on 15 January 2004 at an American Medical Association briefing for media. 相似文献

Reducing non-marital childbearing and making nonresidential fathers take greater responsibility for their children were identified as goals of numerous policy changes since the 1980s. Child-support award rates for children born to unmarried parents have been quite low historically, leading lawmakers to focus on increasing both award and payment rates for this group. Nonmarital fathers are also much less likely to have contact with their children. Although evidence suggests that policy efforts increase child support awards and receipt, the link between child support policies, child support outcomes, and father-child contact has received less attention. This paper uses data from the Survey of Income and Program Participation on children born between 1985–1997 to investigate the relationship between child-support award and receipt and the amount of contact that fathers have with their non-residential children. Since it is likely that both of these behaviors are, in part, determined by unobservable characteristics of the father, we estimate an instrumental variables Tobit model. The model is identified by our assumption that child support policy variables can impact child support awards and payments, but father-child contact cannot be directly legislated. Our results suggest that there are unintended, but desirable effects of child support establishment and collection. Policies to collect child support not only increase financial resources to families, but through their impact on payments increase visitation and contact between these children and their fathers. The estimated impact of receiving child support on contact is more than 27 days per year.An earlier version of this paper was presented at the Annual Meetings of the American Economic Association, Washington DC, January 2003 and the Annual Meetings of the Association of Public Policy and Management, November 2003.

Adolescent suicide is increasing in the United States and the incidence of suicide gestures and attempts in juvenile correctional facilities is high. The attitudes of correctional staff toward adolescents and toward suicidal behavior may contribute to the increase. Suicide is often the outcome of a progression of problems that have isolated the adolescent from meaningful social relationships. Correctional staff must be aware of the phenomenon of adolescent suicide and be given training to deal with it effectively within the institution. Institutional staff have commonly seen suicide gestures or attempts as acting out behavior rather than a symptom of low self-esteem or inability to cope with institutional placement. This discussion examines the phenomenon of adolescent suicide and the impact the juvenile justice system has on its occurrence. It will also include an examination of interdisciplinary interventive strategies which can be used in an institutional setting. 相似文献

The regulatory environment is assumed to be characterized by changing labor costs and productivity, and by the existence of set-up costs for rate reviews. If the commission behaves myopically, price changes are shown to occur only when a threshold deviation of actual from target return is reached. During periods where productivity (wage) increases predominate, the actual return is thus consistently higher (lower) than the target level. If, however, the commission incorporates dynamic trends into its decision-making process, there are intervals where actual return both exceeds and falls short of target levels; on average, the firm earns over time a return that is approximately equal to the target level. 相似文献
