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

While reports of suicide by smothering and strangulation are common, suicide by choking is far more rare. In addition to the act being difficult to carry out, suspected cases are not easily distinguished from accidental or homicidal deaths. Here, we present a case of suicide by choking on toilet paper in a patient with a long history of schizophrenia. The case was ruled a suicide based on the patient having been witnessed in a previous unsuccessful attempt of the same act.  相似文献

The first part of this article highlights important judicial developments involving employee benefits and the Employee Retirement Income Security Act of 1974 ("ERISA"), as amended, during the latter part of 2003 and the first part of 2004, including the most significant U.S. Supreme Court and federal circuit court decisions. The second part covers recent legislative and regulatory developments in employee benefits law. This article is not meant to be exhaustive, but discusses the more important developments during 2003-2004, with particular focus on issues of concern to the insurance industry.  相似文献

It is commonly suggested that social housing is allocated on the basis of 'need'. The authors, however, suggest that the concept of risk provides a much better explanation of the complex interplay of interests involved in the allocation process. In particular, risk explains developing allocation methods in low-demand areas. The thesis is exemplified by drawing upon data derived from the authors' original research on the rehousing of sex offenders.  相似文献
