Rethinking Timing of First Sex and Delinquency 总被引:1,自引:1,他引:0
Harden KP Mendle J Hill JE Turkheimer E Emery RE 《Journal of youth and adolescence》2008,37(4):373-385
The relation between timing of first sex and later delinquency was examined using a genetically informed sample of 534 same-sex
twin pairs from the National Longitudinal Study of Adolescent Health, who were assessed at three time points over a 7-year
interval. Genetic and environmental differences between families were found to account for the association between earlier
age at first sex and increases in delinquency. After controlling for these genetic and environmental confounds using a quasi-experimental
design, earlier age at first sex predicted lower levels of delinquency in early adulthood. The current study is contrasted
with previous research with non-genetically informative samples, including Armour and Haynie (2007, Journal of Youth and Adolescence, 36, 141–152). Results suggest a more nuanced perspective on the meaning and consequences of adolescent sexuality than is commonly
put forth in the literature.

The present study examines how exposure to relational aggression at school is associated with adolescents’ perceptions of,
and participation in, a hostile school environment. Participants were 1,335 African American and European American adolescents
in grades 7 through 12 (52% female, 49% African American). Results indicate that exposure to relational aggression is associated
with several components of adolescents’ perceptions of the school climate. Adolescents exposed to high levels of relational
aggression perceived their school to be less safe, and were less pleased with the general social atmosphere at school. Moreover,
for males, but not females, exposure to relational aggression was associated with carrying a weapon to school. Implications
and suggestions for future research are discussed in terms of working toward safer school environments for adolescents.

A striking common characteristic in many Western countries at the turn of the millennium is the debate on the role of private actors in public health care systems. Following the long line of Norwegian political scientists paying attention to attitudes towards privatization, this article uses data from 2005 on medical specialists to investigate their preferences for private welfare services, and to uncover the relative role of political ideology and self-interest in affecting their attitudes. So far, few attempts have been made to test in depth the impact of ideology and self-interest as alternative explanations of the attitudes of a professional group toward a policy issue that is important to its interests. The analysis documents the fact that both public and private specialists display scepticism towards leaving welfare services in the hands of private actors. The empirical model for the multivariate analysis builds on the large body of literature on political attitudes, and incorporates variables that are derived from economic and psychological theories in order to test the impact of ideology and subjective self-interest (emphasis on high salary for job satisfaction) and objective self-interest (private economy). In addition, the model also controls for a vector of individual characteristics and professional background. For the group of full-time public specialists, both subjective and objective self-interest, together with ideology, turns out to be the major determinants of view on private welfare services. The attitudes of the private specialists are, on the other hand, not at all affected by self-interest – only by ideology. 相似文献

While there is a growing academic literature about mail-in ballots, there has been no serious academic research to date on overseas voters, even though the counting of overseas military ballots figured into the 2000 presidential election controversy. The participation of nearly 4 million overseas voters, both civilian and military, is governed by the Uniformed and Overseas Citizens Absentee Voting Act. The authors examine the reported perceptions of military and nonmilitary voters covered by this legislation using two surveys funded by the U.S. Election Assistance Commission, focusing on their perceptions of electronic means of transmitting voting materials. The authors find that civilian overseas citizens have a harder time registering and voting than military overseas citizens; that the key factor is the timely transmission of voting materials; and that, despite privacy concerns, electronic transmission of voting materials is viewed favorably. 相似文献

The existing literature on economic sanctions has rarely addressed the key question of comparing the effectiveness of positive and negative sanctions. It is the contention of this study that positive sanctions can potentially be more effective, even in cases where contentious "high politics" issues are being negotiated, relations between the states concerned are tense and militarized, and the state being targeted with sanctions has substantial military power. This assertion will be tested in a set of case studies drawn from German-Polish and German-Russian/Soviet relations from the nineteenth century to the present. It will be shown that positive sanctions can be used effectively, both as "specific" sanctions to influence a target state on one particular issue, and as "general" sanctions, which aim to change the state's behavior as a whole in a more slow and subtle process. 相似文献

Abstract: The Health Protection Branch (hpb ) of Health Canada has recently undergone considerable policy and organizational renewal, with numerous and broad‐ranging implications for the evaluation of drug product safety and efficacy. From a public‐health perspective, however, the criteria used to develop organizational and policy change at the hpb have provided a sub‐optimal basis for reform, due primarily to the many forms of market failure to which the regulation of pharmaceuticals is subject. For example, thepartnership andefficiency criteria that guided policy renewal have led to the transfer of important responsibilities to partners, with the potential for either a conflict of interest or inadequate information, for which the legal basis is not always clear. The resulting realignment of the hpb's roles and responsibilities may be characterized as leading to a shift from a comprehensive approach to public‐health protection to one based on strategic risk management, with responsibilities dispersed among government, industry, academia and consumers. The rebalancing of goals in the redesign of the regulatory process suggests a change in the role of the state in the context of public‐health protection and highlights issues of concern to the public interest that may not be fully recognized as deregulation occurs in other sectors of the economy. Sommaire: La Direction générale de la protection de la santé (dgps ) de Santé Canada vient de subir un vaste remaniement de politiques et d'organisation qui entraîne de nombreuses et profondes répercussions sur l'évaluation de la sûreté et de l'efficacité des produits pharmaceutiques. Cependant, du point de vue de la santé publique, les critères auxquels on a fait appel pour modifier les politiques et l'organisation de la dgps n'ont permis qu'une base de réforme sous‐optimale, à cause surtout des nom‐breux genres de défaillance du marché qui affligent la réglementation des produits pharmaceutiques. Par exemple, les critières depurtenariat etd'efficacité qui ont guidé le remaniement des politiques ont amené le transfert d'importantes responsabilites à des partenaires moyennant le risque de. conflit d'intérêts ou d'informations inadéqaates, sans pour autant assurer une base juridique Claire. On pourrait donc dire que cette réorientation des rôles et responsabilités de la dgps fait que l'on passe d'une approche globale en matière de protection de la santéà une gestion stratégique du risque, la responsabilité en étant dispersée parmi le gouvernement, l'industrie, les milieux universitaires et les consommateurs. Le rééquilibrage des objectifs dans le remaniement du processus de réglementation suggère une évolution du rôle de l'État en ce qui concerne la protection de la santé publique; il met aussi en relief des questions d'intérêt public qui n'ont peut‐être pas été reconnues alors que la déréglementation prend lieu dans d'autres secteurs économiques. 相似文献

The National Institute of Forensic Toxicology, Oslo, receives blood and urine samples from all Norwegian drivers apprehended on suspicion of driving under the influence of alcohol or drugs. In 1983 we received samples from 1446 drug-suspected drivers, out of which 445 underwent toxicological analysis. The drugs found most frequently were tetrahydrocannabinol (THC) (n = 199), diazepam (n = 166) and amphetamine (n = 102). A cautious interpretation of the data indicate that about 200 of the 445 subjects selected for toxicological analysis drove under severe influence of drugs. Because of the high percentage of submitted cases not analysed for drugs, this figure represents a minimum estimate. Compared with the results from 1978, we found a several-fold increase in detections of THC and amphetamine in 1983. The number of diazepam detections did not increase in a similar way, but we estimated that the diazepam detections would have increased 3-fold if we had analysed as frequent for this drug in 1983 as in 1978. 相似文献

The aims of the authors in this paper has been to check the diagnostic ability of the Cathepsin A, B and D concentrations in the skin wound edges to the differential diagnosis between vital and postmortem wounds. We have studied 56 domestic pigs grouped in seven experimental series consisting of 8 animals in each, according to the time (0, 5, 15, 30 min and 1, 3 and 6 h) after the injury. The enzymatic activities were investigated following the methods by Bowen and Davison Biochem. J., 131 (1973) 417-419, Suhar and Marks J. Biochem., 101 (1979) 23-30 and by Anson (modified by Yamamoto, Eur. J. Biochem., 95 (1979) 459-467) for Cathepsin A, B and D, respectively. For the differential diagnosis between vital and postmortem wounds, our results showed that the most useful markers studied are the Cathepsin A and D activities, Cathepsin D that of the first one. 相似文献
