Self-report questionnaires are frequently used in youth research, but doubt remains whether total anonymity affects the results. This study compared the responses of 704 mainly 16–17-year-old adolescents to self-report measures of various health indicators in 2 groups: anonymous and confidential collection. For most health indicators no significant differences were found. Perceived health, use of alcohol, and aggressive behavior (for boys) were reported significantly less frequently in the confidential group (small effect size). It appeared that pupils with high scores on social desirability do not respond differently at most health indicators in the 2 conditions. For most health characteristics, epidemiologically useful outcomes may be derived from confidential self-report measures, which are also valuable for detecting individual at-risk children. Similar studies in lower grades and other types of education should confirm the results.Youth Department, Municipal Health Service Rotterdam area.

The role of interpersonal sensitivity in the relation between romantic stress and depression was examined in 55 adolescent girls from an inner-city high school. Depression, interpersonal sensitivity, and chronic and episodic romantic stress were measured at two time points, 6 months apart. Interpersonal sensitivity was found to moderate the longitudinal relation between romantic stress (both chronic and episodic) and depression. In contrast, interpersonal sensitivity did not potentiate depressive responses to non-romantic interpersonal stress, suggesting particular importance of stress in the romantic domain for adolescent girls. Results indicate that girls' sensitivities to romantic relationship stress should be specifically addressed in depression prevention and intervention programs.Received her PhD from the University of Southern California. Research interests include the influence of romantic relationship factors, such as romantic stress and dating violence, on the development of depression during adolescence.Received her PhD from the University of California, Los Angeles. Research interests include the interplay between adolescent depression, personality disorder symptoms, and interpersonal variables including adjustment in friendships and romantic relationships.Research interests include cognitive and interpersonal factors in adolescent depression.  相似文献

Already the world’s second largest energy consumer, China has accounted for more than a third of the increase in global oil demand since 2000. Due to infrastructural bottlenecks as well as supply shortages, intensified by sustained growth, the PRC is likely to become an increasingly important factor in global oil and gas markets, and to pursue an increasingly active energy diplomacy. Reducing energy vulnerability will be a key imperative. The PRC is striving to reduce its energy vulnerability by: (1) promoting energy efficiency; (2) diversifying away from its heavy reliance on coal and oil, toward nuclear power and natural gas; (3) improving domestic energy infrastructure; (4) promoting national energy champions; (5) deepening reliance on congenial nations; and (6) reducing reliance on sea lanes dominated by the U.S. Navy. Kazakhstan, Iran, Russia, Venezuela, Australia, and African energy producers are special priority targets of its energy diplomacy, which is likely to become more salient in China's overall foreign policy in coming years.  相似文献

The majority of Asian states have not signed onto the major international refugee law instruments which promote refugee recognition and protection. Yet, second to Africa, the Asian region has had the highest number of refugees since the Second World War. Three explanations are usually offered to explain this puzzle —“good neighbourliness”, “economic costs” and “social disruption”. In this article I argue that each is flawed in important ways and then develop an alternative by explaining how limited Asian involvement in the drafting of international refugee law has led Asian states to reject Eurocentric refugee recognition practices.  相似文献

我国法律对于违法少年的处遇主要包括工读教育、治安处罚、收容教养、劳动教养、收容教育、强制戒毒等方式,从现状来看,这些制度体现出执行主体的行政性、程序的不正当性、目的的惩罚性、依据的违法、违宪性等特点,与当今少年司法的理念背道而驰。改革违法少年的处遇方式,将其纳入少年司法的范畴,成为今后我国完善少年法的重大课题之一。  相似文献

In this paper, the authors use the Bush administration's management grades from the Program Assessment Rating Tool (PART) to evaluate performance budgeting in the federal government—in particular, the role of merit and political considerations in formulating recommendations for 234 programs in the president's fiscal year 2004 budget. PART scores and political support were found to influence budget choices in expected ways, and the impact of management scores on budget decisions diminished as the political component was taken into account. The Bush administration's management scores were positively correlated with proposed budgets for programs housed in traditionally Democratic departments but not in other departments. The federal government's most ambitious effort to use performance budgeting to date shows both the promise and the problems of this endeavor.  相似文献
