Prevalence differences in depressive symptoms between the sexes typically emerge in adolescence, with symptoms more prevalent among girls. Some evidence suggests that variation in onset and progression of puberty might contribute to these differences. This study used a genetically informative, longitudinal (assessed at ages 12, 14, and 17) sample of Finnish adolescent twins (N = 1214, 51.6% female) to test whether etiological influences on depressive symptoms differ as a function of pubertal status. These tests were conducted separately by sex, and explored longitudinal relationships. Results indicated that pubertal development moderates environmental influences on depressive symptoms. These factors are more important on age 14 depressive symptoms among more developed girls relative to their less developed peers, but decrease in influence on age 17 depressive symptoms. The same effects are observed in boys, but are delayed, paralleling the delay in pubertal development in boys compared to girls. Thus, the importance of environmental influences on depressive symptoms during adolescence changes as a function of pubertal development, and the timing of this effect differs across the sexes.  相似文献

The Interstate Compact on the Placement of Children (ICPC) is an agreement between all 50 states and the District of Columbia governing the process of placing a foster child out of state. Notorious for its long wait times and system backlog, the ICPC presents a host of problems for children attempting to move mere minutes across state lines to be with a relative or kin placement instead of state foster care. In an effort to make this process smoother, 18 different “border agreements” have been adopted by several neighboring states across the U.S. Such border agreements give temporary placement licenses to relatives and kin while the ICPC process is ongoing. While this is a good start towards a solution, the ICPC could be further streamlined if border agreements were used more widely, especially in regional contexts. This article considers the possibility of such a regional agreement between the District of Columbia, Maryland, and Northern Virginia (known as the “DMV”). By comparing and contrasting two existing border agreements in these three jurisdictions, a regional DMV border agreement can be created implementing the best terms of both agreements.  相似文献

Alexander Hamilton's career provides much insight about responsible public administration. This article emphasizes his linking of character and competence in public administration to our American constitutional form and values. His “prudent constitutionalism” yielded a normative theory of action that remains relevant though largely unexamined.  相似文献
