Underage drinking is among the most serious of public health problems facing adolescents in the United States. Recent concerns have centered on young women, reflected in media reports and arrest statistics on their increasing problematic alcohol use. This study rigorously examined whether girls’ alcohol use rose by applying time series methods to both arrest data, Uniform Crime Reports, and self-report data from Monitoring the Future, a nationally representative long-term survey gathered independently of crime control agents. All self-reported drinking behaviors across all age groups show declining or unchanged female rates and no significant change in the gender gap, while the official source displays a steady narrowing gender gap and some increase of female arrest rates for liquor law violations. Results indicate that social control measures applied to underage drinking have shifted to target young women’s drinking patterns, but their drinking has not become more widespread/problematic. Girls’ increased alcohol use and abuse is a socially constructed problem, rather than the result of normalization of drinking or more strain in girls’ lives. Future underage drinking policies and practices that apply legal intervention strategies to less chronic adolescent drinking behaviors will increase the visibility of girls’ drinking.  相似文献

Extracurricular activities provide a key context for youth development, and participation has been linked with positive developmental outcomes. Using data from the 4-H Study of Positive Youth Development (PYD), this study explored how the intentional self regulation ability of youth interacted with participation in extracurricular activities to affect PYD among adolescents living in neighborhoods with relatively low ecological assets. In total, 545 youth were included in the study (50.3% female). Most of the youth were European American (41%) or Latino (37%; African American, 10%; Asian American, 7%; Native American, 4%; and other, 1%). In general, youth with the greatest capacity to self regulate benefitted the most, as compared to their peers with less capacity to self regulate, from involvement in extracurricular activities. Consistent with a developmental systems perspective, and specifically with bioecological theory, the findings from this study confirmed that, within lower asset settings, children with the most positive person-level factors (intentional self regulation) benefit the most from proximal processes such as extracurricular activity involvement.  相似文献

From 9/11 in the U.S. to train, subway, and airport bombings elsewhere, individuals frequently must make political decisions in the shadow of terrorist attacks. To date, few studies have examined how times of terror threat influence voters’ decision-making processes. Using data generated from three experiments we show that, in times of terrorist threat (compared to good times), individuals weight leadership more heavily in the voting booth. Our results also shed light on how much weight is given to other determinants of the vote (issues and partisanship) across these two conditions.  相似文献

This article explores three formats for interstate relations developed by, or at least significantly influenced by Germany in the post-Cold War period: the Petersburg Dialogue, the German–Russian–Polish Trialogue and the Weimar Triangle. An examination of the form and function of each of these formats is followed by a discussion of what these formats have in common and why they are worthy of further study. The paper addresses whether this ‘variable geometry’ of Germany's foreign policy of trust-building is likely to survive a period of turbulent relations or changes in leadership and, furthermore, how the effectiveness of dialogues, trialogues and triangles might be evaluated.  相似文献
