Athletic Involvement and Adolescent Delinquency   总被引:1,自引:0,他引:1  
Athough conventional wisdom suggests that organized sport deters delinquency by building character, structuring adolescents’ time, and providing incentives for socially approved behavior, the empirical evidence to date has been mixed. Based on a sample of approximately 600 Western New York adolescents, the present study examined how self-reported jock identity, school athlete status, and frequency of athletic activity differentially influenced a range of delinquent behaviors. Neither athlete status nor frequency of athletic activity predicted these behaviors; however, jock identity was associated with significantly more incidents of delinquency. This finding was robust across both gender and race. Follow-up analyses indicated that jock identity facilitated both minor and major delinquency, with major delinquency effects for white but not black adolescents.

In an Opinion by the Advocate General, several ghosts finallyhave been put to rest in a ferocious 30-year jockeying for positionbetween brand owners and European importers over the abilityof importers to replace existing brand owner trade marks withthe importer's own brand names (ie repackaging) for purposesof the European market harmonization.  相似文献

In 1986 the staff of the U.S. Office of Management and Budget reviewed issues concerning the possible development of a federal capital budget. As part of this study, a survey of all 50 states was conducted concerning state capital budgets. This paper summarizes the results of the survey. According to the survey responses, 42 states have capital budgets. Of these 42, 37 generally borrow to finance some public capital and 5 generally do not. Of the 8 states that said they do not have a capital budget, 4 generally borrow to finance some public capital and 4 generally do not. The survey also found that the form of a governor's capital budget, the way legislatures enact capital spending, the coverage of the capital budget, and the method of financing capital vary widely among states, making it virtually impossible to define a state capital budget in a precise way. Large amounts of state capital spending, especially for transportation, are generally not included in state capital budgets.  相似文献

Carboxyhemoglobin (COHb) levels were determined in stored blood samples from 91 infants diagnosed to have died from the sudden infant death syndrome (SIDS) (0.59+/-0.41%, excluding one outlying value of 10.83%); 48 age-matched controls (0.53+/-0.38%); and three individuals who died from fire related causes (41+/-20%). No statistical differences in COHb levels were detected between blood from SIDS and control infants (p = 0.43).  相似文献

Despite recent declines in overall sexual activity, sexual risk-taking remains a substantial danger to US youth. Existing research points to athletic participation as a promising venue for reducing these risks. Linear regressions and multiple analyses of covariance were performed on a longitudinal sample of nearly 600 Western New York adolescents in order to examine gender- and race-specific relationships between jock identity and adolescent sexual risk-taking, including age of sexual onset, past-year and lifetime frequency of sexual intercourse, and number of sexual partners. After controlling for age, race, socioeconomic status, and family cohesion, male jocks reported more frequent dating than nonjocks but female jocks did not. For both genders, athletic activity was associated with lower levels of sexual risk-taking; however, jock identity was associated with higher levels of sexual risk-taking, particularly among African American adolescents. Future research should distinguish between subjective and objective dimensions of athletic involvement as factors in adolescent sexual risk.Research Scientist at the Research Institute on Addictions of the University at Buffalo.

This field study reports on a cross-site evaluation of dependency courts in communities receiving federal funding to implement the Greenbook initiative, a multisite demonstration for community improvement of coordinated responses to families victimized by domestic violence and child maltreatment. This article focuses on the dependency court, where child maltreatment cases are heard, specifically court participation in collaborative activities and court practice improvements. Findings indicate that perceptions of judicial leadership varied considerably by site. Cross-training appeared to increase over time, particularly with court staff. Collaborative efforts emerged across the Greenbook initiative with regard to the courts, and some innovative practices appeared within Greenbook sites, such as separate case plans for perpetrators and victims of violence in families, reducing the likelihood of controversial failure to protect charges. Results also highlight challenges inherent in changing court practices. Research and practice implications are discussed, focusing on relevance to other communities attempting to work collaboratively with the court system.  相似文献
