Pubertal Development Moderates the Importance of Environmental Influences on Depressive Symptoms in Adolescent Girls and Boys

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.     

Lebron v. Gottlieb Memorial Hospital: capping medical practice reform in Illinois

On February 4, 2010 the Illinois Supreme Court struck down Illinois' medical practice reform bill, P.A. 94-677, when it decided Lebron v. Gottlieb Memorial Hospital. Although the court only considered the unconstitutionality of the cap on non-economic damages contained in that bill, an inseverability provision resulted in the invalidation of all of its provisions. The end result of the Lebron decision extends much further than the striking of the cap on non-economic damages. It affects such areas as medical liability insurance law, physician discipline, public disclosure of information, the admissibility of physician statements into evidence, and expert witness standards. The Lebron holding has raised a significant obstacle to the implementation of a wide range of legislative measures intended to improve both the delivery and quality of healthcare services in Illinois. This article explains the impact of Lebron in these collateral, but important, areas of the law.

COMMENTS ON NETWORK NEUTRALITY

The term "price discrimination" has been used to vilify itspractitioners since the term's inception in economics. Pricediscrimination is considered evil because discrimination isconsidered, in most contexts, as evil. If instead we describedthis common phenomenon as price distinction instead of pricediscrimination, the general field of thought on the matter would,most likely, be extremely different. If a producer engages in"distinguishing" prices instead of discriminating prices, theworld would be a more rational place, because economic discriminationis so often socially beneficial. The network neutrality argumentis no different. The debate essentially addresses the issueof limiting a network provider's ability to engage in pricedistinction before the fact. The model of a toll road presents an acceptable framework foranalyzing network neutrality. It has been used frequently toanalogize the Internet     

African American Oxford House residents: sources of abstinent social networks

The current study found that African American residents of Oxford House (OH) used Narcotics Anonymous (NA) at high rates, and that both OH and NA strongly contributed to abstinent social networks. Having siblings and other family members in one's network predicted substance use among network members, whereas spouses, parents, and children did not have an effect on the rate of substance use. These findings suggest that OH and NA may be effective sources of abstinent social support for African Americans recovering from substance abuse. However, family members are well represented in the support networks of African Americans in OH.
