As part of a larger study, forty-two female police officers in New York City were asked to articulate their motivations for selecting police work as a career. The reasons given are presented, and comparisons are made with the reasons given in the few other studies of male and female officers. It is felt that a better understanding of the motivations behind this career choice will help the police agencies recruit more effectively and more appropriately select candidates for openings.  相似文献

This field study examined whether participants of a traditional, end-of-semester pub crawl in a college campus community had higher levels of intoxication than non-participating bar patrons on the same night as the event. A total of 693 bar patrons participated in the study. Anonymous interview and breath alcohol concentration (BrAC) data were collected from pedestrians in a bar district at the end point of the pub crawl route between 10:00 p.m. and 3:00 a.m. on the night of the event during three different semesters (November, 2007, May, 2008, and May, 2009). A multivariate model adjusting for participant demographics and drinking variables showed that participation in the pub crawl was associated with a 70% reduced risk of being highly intoxicated (i.e., BrAC ≥ 0.08 g/210 L). The lower intoxication levels among pub crawl participants may have implications for harm reduction practices at high-risk drinking events. These implications are discussed.  相似文献

In a study of subjects in drug rehabilitation programs, cocaine and cocaine metabolite levels were determined in the hair of 75 subjects who had produced cocaine-positive urine results. The hair was analyzed after being washed with the 3.75 h wash procedure developed by this laboratory. In addition, results of testing 73 non-users are presented, as well as levels of cocaine, benzoylecgonine (BE), cocaethylene, and norcocaine from workplace population samples. The data support a recommendation of reporting as positive a sample with cocaine of 500 pg/mg hair and either a 5% ratio of benzoylecgonine (BE) to cocaine in samples, or the presence of cocaethylene at 50 pg/mg hair, or norcocaine at 50 pg/mg hair for samples < or =2000 pg cocaine/mg hair. For samples with cocaine present at >2000 pg/mg hair, the data indicate that a ratio of 5% BE may be an overly conservative approach. In appropriately washed hair samples, cocaine users can produce hair levels of <5% BE and thus a minimum BE cutoff in lieu of a ratio could be considered.  相似文献

State governments have historically dominated corrections policy, with little federal intervention. But over the past two decades, the trend has been toward "nationalizing" corrections policy, with less interstate variation and more federal standards, through the Safe Streets Act and other legislation. As federal funding declines, it may be expected that there will be a hiatus in state corrections reform, though national standards may survive if the federal courts continue to require state correctional systems to comply with federal laws previously implemented.  相似文献

Motor vehicle exhaust gas suicide (MVEGS) is the second most frequent method of suicide in Victoria, Australia. It is a highly lethal method of suicide with 1.5 deaths for every hospital admission. Australian regulations require all vehicles manufactured since 1998 to have a maximum carbon monoxide exhaust emission level of 2.1 g/km, reduced from the previous level of 9.6 g/km. Information surrounding all Victorian MVEGS between 1998-2002 was analyzed to determine whether suicides occurred in vehicles with the lower emission levels. Between 1998-2002, 607 suicides by this means were recorded while just 393 hospital admissions were recorded for the same period. Mean carboxyhaemoglobin levels were significantly lower in fatalities using vehicles manufactured from 1998, however suicide still occurred in these vehicles (n = 25). The extent to which the new regulations contributed to the relatively low rate of suicide in vehicles less than 5 years old compared to their frequency in the fleet remains unknown. Based on international experience and the age of the Victorian vehicle fleet, it may take well over a decade until substantial decreases in MVEGS are observed in the absence of active preventive measures.  相似文献

This study examined risk and protection for adolescent problem behavior and depressive symptomatology in an average-risk sample of 11th graders. Using a socioecological perspective, we aggregated risk factors for adolescent problem behavior and depressed mood by 3 social contexts: i.e., family and peer contexts, and a context comprising the most important nonparental adult (VIP) in respondents' lives. Protective factors associated with these 3 contexts were also included in the analyses. We tested separate models (including outcome-specific risk and protective factors) for predicting problem behaviors and depressive symptoms; the models demonstrated divergent validity. Risk and protective factors accounted for 49% of the variance in problem behavior and 49% in depressive symptoms. Tests of interactions between risk-aggregates and protective factors yielded several significant cross-context buffering effects in the problem behavior model, but none in the depressive symptoms model. Parents' and VIP's perceived sanctions buffered adolescents against high risk for problem behavior emanating from the peer context. Additionally, perceived peers' sanctions buffered youths against risk emanating from each of the 3 contexts.  相似文献

Multiple sources of stress and deficient problem-solving skills have been identified among maltreating parents. In the present study, a problem-solving intervention was evaluated with a multiply distressed, abusive and neglectful mother. Problem-solving skills were trained sequentially in a multiplebaseline design. Training focused on improving judgments related to child care and managing daily stress. The impact of training was examined in relation to problem-solving skill improvements, as well as social insularity, affect, and stress which appeared to compromise child care abilities. Problem-solving training resulted in a substantial increase in generation of alternative solutions and in the quality of plans to implement solutions on both training and generalization vignettes. Moreover, training resulted in positive changes in social insularity, negative affect, and self-reported stress and anxiety. Most of these gains were maintained at 1- and 5-month follow-ups. There were no further reports of child maltreatment during the 21 months following intervention.  相似文献
