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.

Two features of citizen response to Congress can be taken as grounds for concern. First, Americans know relatively little about Congress, and especially about congressional procedures and policy output. Second, Congress typically emerges as the least respected political institution. Although these matters are troubling when viewed individually, more disturbing is the dilemma posed when knowledge and attitudes toward Congress are viewed in tandem. It appears that citizens who know Congress the best like Congress the least. Consequently, a sophisticated polity and a well-respected legislature seem fundamentally incompatible. This article seeks to resolve this dilemma, contending that there is nothing about knowledge per se that leads citizens to view Congress unfavorably. Rather, differences in knowledge levels alter the considerations citizens bring to bear when evaluating Congress, with the best-informed individuals constructing judgments on the basis of the most relevant Congress-specific criteria while less knowledgeable citizens employ readily available but more peripheral criteria. 相似文献

We use data from the Survey of Income and Program Participation (SIPP) to investigate the impact that child Supplemental Security Income (SSI) enrollment has on household outcomes, including poverty, household earnings, and health insurance coverage. The longitudinal nature of the SIPP allows us to control for unobserved, time‐invariant differences across households by measuring outcomes in the same household in the months leading up to and immediately following the first reporting of child SSI income. Our regression analyses demonstrate that for every $100 increase in household SSI income, total household income increases by roughly $72, reflecting some modest offset of other transfer income and conditional household earnings. Our analyses further demonstrate that child SSI enrollment is associated with a statistically significant and persistent reduction in the probability that a child lives in poverty of roughly 11 percentage points. Additional analyses suggest that program enrollment has virtually no impact on health insurance coverage because most new SSI recipients have health insurance from Medicaid or another source at the time of enrollment. © 2007 by the Association for Public Policy Analysis and Management 相似文献

Does environmental lobbying affect the probability of environmental treaty ratification? Does the level of government corruption play a role for the success of such lobbying? In this paper, we propose that a more corruptible government may be more responsive to the demands of the environmental lobby. We use several stratified hazard models and panel data from 170 countries on the timing of Kyoto Protocol ratification to test this hypothesis. We find that increased environmental lobby group activity raises the probability of ratification, and the effect rises with the degree of corruption. 相似文献

The rapidly changing political, economic, and security policies in the Soviet Union and Eastern Europe in late 1989 and 1990 have added to the complications faced by Chinese leaders since they decided to suppress the unprecedented large-scale pro-democracy demonstrations in Chinese cities in spring 1989. These changes had an obvious “ripple effect” in China, encouraging prodemocracy forces and alarming Chinese leaders. They attracted strong positive attention from the developed countries of the West and Japan, and international financial institutions and businesses. This came at the indirect expense of China. And they accelerated changes in world politics (especially in U.S.-Soviet relations) and in the politics of government decision making in the West that promised to reduce China’s relative influence in world affairs in the 1990s. The prospect of reduced influence abroad and curbed economic contacts did not appear to be sufficient cause for Beijing leaders to markedly change existing policies. Chinese leaders in mid-1990 appeared focused on issues of internal political power at a time of leadership transition. Significant changes in policy appeared most likely to await leadership changes as Deng Xiaoping and other aged leaders die or are incapacitated. 相似文献
