This study examined the construct validity of antisocial personality disorder (ASPD) diagnosed in adolescence. Boys and girls
were grouped by history of DSM-III-R conduct disorder (CD) and ASPD: Controls (n=340) had neither diagnosis; CD Only (n=77) had CD by age 17 but no ASPD through age 20; Adolescent ASPD (n = 64) had ASPD by age 17. The Adolescent ASPD group was then compared to 20 young adult men who met criteria for ASPD (ASPD group). As expected, the Adolescent ASPD group had significantly more depression and substance use disorders, a greater performance>verbal IQ discrepancy, more deviant
peers, and poorer academic functioning than the CD Only group and Controls. The Adolescent ASPD and ASPD groups did not differ on most variables. Results support the construct validity of Adolescent ASPD and suggest that such a diagnosis could help identify adolescents at risk for persistent antisocial behavior.

Some scholars argue that the author of the majority opinion exercises the most influence over the Court's opinion-writing process and so can determine what becomes Court policy, at least within the limits of what some Court majority finds acceptable. Other students of the Court have suggested that the Court's median justice effectively dictates the content of the majority opinion: whatever policy the median justice most wants, she can get. We test these competing models with data on Supreme Court decision making during the Burger Court (1969–86). While we find substantial evidence for both models, the agenda control model gains greater support. This suggests that opinions on the Court on each case are driven, in general, by the interaction of three key variables: the policy preferences of the majority opinion author, the policy preferences of the median justice, and the location of the legal status quo . 相似文献

Smoking bans are gaining widespread support in the United States and other countries. While supporters argue that bans are necessary to resolve market failures associated with negative externalities, the Coase Theorem predicts that, under various conditions, private markets internalize negative externalities. We examine the smoking issue within the framework of the Coase Theorem and hypothesize that smoking bans misallocate air space resources shared by smokers and nonsmokers. Because smoking bans shift ownership of scarce resources, they are also hypothesized to transfer income from one party (smokers) to another party (nonsmokers). Supporting evidence for these hypotheses is provided by an examination of a comprehensive smoking ban imposed in San Luis Obispo, CA. 相似文献

This paper uses anecdotal evidence to identify a group of firms that had significant ties to President Lyndon Johnson and determines the effect of Johnson's unexpected rise to the Presidency on the market value of these firms. The unexpected nature of President Kennedy's death eliminates the confounding event problem typically associated with election results. We are able to identify four separate portfolios of firms that had political ties to Lyndon Johnson. Our research suggests that the market expected significant benefits to accrue to these firms as a result of Johnson's becoming President. When Catholic John Kennedy and Johnson were running together in 1960 a joke hop-scotched around the parties in Texas and Washington that Kennedy had told Johnson, “Lyndon, when we get elected I'm going to dig a tunnel to the Vatican,” and Lyndon had replied, “That's OK with me as long as Brown & Root gets the contract” (Dugger, 1982: 286). 相似文献
