This paper examines the association between adolescent pregnancy and socioenvironmental, physical, and mental health problems in 1590 inner-city females aged 13–18 who use health clinics. Adolescents who have become pregnant, those who are sexually active but never have been pregnant, and those who are sexually inactive are compared. The sexually active youngsters come from more psychosocially disadvantaged backgrounds than their sexually inactive peers; the sexually active girls who become pregnant come from more psychosocially disadvantaged backgrounds than those who have never been pregnant. Despite this, the youths who have become pregnant do not have more current relationship problems, more stressful life events, or worse physical health than the never-pregnant sexually active youths. Although sexually inactive youths have the lowest rates of mental health problems, adolescents who have been pregnant have lower rates of anxiety and conduct disorder symptoms than those who are sexually active but never pregnant.Supported by the Robert Wood Johnson Foundation. Fieldwork conducted by Survey Research Associates.Research interests include adolescents and children, parenting, and families.Research interests include epidemiology of child and adolescent psychiatric disorder.Research interests include psychiatric epidemiology/deviant behavior.Research interests include mental health and statistical issues.Research interests include health behavior and mental health issues. 相似文献

Given local, regional, national, and global events of the last few years and the ever-increasing service roles and expectations of county governments, American counties warrant greater scholarly attention. To guide researchers, the research agenda published in this journal 15 years ago has been refined and expanded. This 11-point agenda includes fiscal capacity and responsibility; the role of structure, politics, and political participation; intergovernmental relations and networking; professionalism; service delivery; environmental issues; population changes; managing conflict and promoting integration; terrorism and security; information technology; and economic development. In addition, five database concerns and needs that pose significant challenges to researchers are identified and presented for consideration. 相似文献

当代美国自然法理论走势 总被引:2,自引:0,他引:2
自然法理论可从道德的、法律的等多个角度加以探讨。凡主张法之为“法”必得满足道德要求 ,或者说 ,法最重要的特征之一乃法具备的道德性这一观点 ,均属“交叠理论”。然 ,交叠理论与概念性法哲学相互交叉、渗透 ,衍生出多种不同的表达方式。本文在此基础上 ,本文对当代美国自然法理论的基本走向和流派进行了考查 ,其中 ,尤以菲尼斯、富勒和德沃金等人的理论为重。 相似文献

Why do states persist in enduring, expensive conflicts when the costs seem so high, the potential benefits, at best, somewhat ambiguous? This article suggests that emotional psychology can provide some insights into this problem. Decision-makers construct a vision of the future that is greatly informed by affect. How they feel in the present has a big impact on their conception of events and their decisions about them. The risks they are prepared to take, the desires they anticipate having in future, the lessons of the past they draw on—all are constructed under the influence of current emotions, and all may encourage the persistence of conflict beyond a point at which more dispassionate minds might desist. This theoretical argument is then illustrated with a discussion of US policy-making in the Vietnam War. 相似文献
