The purpose of this study was to explore individual- and school-level policy characteristics on student smoking behavior using an ecological perspective. Participants were 24,213 (51% female) Grade 10–11 students from 81 schools in five Canadian provinces. Data were collected using student self-report surveys, written policies collected from schools, interviews with school administrators, and school property observations to assess multiple dimensions of the school tobacco policy. The multi-level modeling results revealed that the school a student attended was associated with his/her smoking behavior. Individual-level variables that were associated with student smoking included lower school connectedness, a greater number of family and friends who smoked, higher perceptions of student smoking prevalence, lower perceptions of student smoking frequency, and stronger perceptions of the school tobacco context. School-level variables associated with student smoking included weaker policy intention indicating prohibition and assistance to overcome tobacco addiction, weaker policy implementation involving strategies for enforcement, and a higher number of students smoking on school property. These findings suggest that the school environment is important to tobacco control strategies, and that various policy dimensions have unique relationships to student smoking. School tobacco policies should be part of a comprehensive approach to adolescent tobacco use.  相似文献

Twenty years after the events of 1989, most American academics and policymakers continue to see the end of the Cold War as a victory for the United States. This Cold War “triumphalism” is based on a number of assumptions which have, in turn, served as important framing devices for US foreign policy. This chapter argues that the “wrong lessons” were learned from the fall of communism in Central and Eastern Europe. These lessons were based on a misreading of both Cold War history, in general, and its endgame, more specifically. This chapter outlines ten such lessons and explores the ways in which they were used to legitimate policies of regime change from above after 9/11. In this way, we can see a direct line between Berlin in 1989 and Baghdad in 2003, one driven by the hubris of both US policymakers and intellectuals.  相似文献

Abstract: Samples containing the toxic castor bean protein ricin have been recently seized in connection with biocriminal activity. Analytical methods that enable investigators to determine how the samples were prepared and to match seized samples to potential source materials are needed. One commonly described crude ricin preparation method is acetone extraction of crushed castor beans. Here, we describe the use of solid‐phase microextraction and headspace analysis to determine whether castor beans were processed by acetone extraction. We prepared acetone‐extracted castor bean mash, along with controls of unextracted mash and mash extracted with nonacetone organic solvents. Samples of acetone‐extracted mash and unextracted mash were stored in closed containers for up to 109 days at both room temperature and ?20°C, and in open containers at room temperature for up to 94 days. Acetone‐extracted bean mash could consistently be statistically distinguished from controls, even after storage in open containers for 94 days.  相似文献

There are few effective treatments of antisocial personality disorder (APD). Preliminary work suggests that the atypical antipsychotic quetiapine can decrease irritability, impulsivity, and aggressiveness. Data were collected from 4 patients with APD who were referred to a maximum-security inpatient psychiatric facility for pretrial evaluation and were treated with quetiapine. Quetiapine was effective in these patients as was indicated by a decrease in symptoms such as impulsivity, hostility, aggressiveness, irritability, and rage reactions. Typical dosage was 600 to 800 mg per day. Patients attributed their willingness to comply with quetiapine treatment to both the effectiveness of the drug and its favorable adverse-event profile. Quetiapine was successfully combined with mood stabilizers, particularly gabapentin, in patients with prominent affective instability. Quetiapine has demonstrated efficacy in aggression, impulsivity, and irritability and has proved to be an effective medication in these patients with APD. In addition, its favorable adverse-event profile makes patients willing to comply.  相似文献

Building on Romano's recent analysis of the United States securitiesregulatory regime, we model competition between professionalauditing associations. We show that such competition is an effectivesubstitute for government regulation, providing an efficientmeans for auditors to signal their service quality. Competitionis likely to lead to stability in the market for auditing services,with neither a "race to the top" nor a "race to the bottom."Monopoly rents are unlikely to be earned by auditors or theirprofessional organizations, and government intervention canbe limited to ensuring that the professional organization'sdisciplinary actions are costly enough to be effective.  相似文献

This article explores First Amendment theory and the role of the media in generating police accountability through public understanding of police organizations. We argue that free speech theory can and should look beyond "abridgment" issues and raise questions about the civic responsibility of the press to inform the public about key governmental institutions. The media's concern with crime news, we found, vastly overshadows its coverage of the police us a complex, in-teresting, and expensive governmental agency. Reporting about police institutional patterns and policies contributes more toward fulfilling First Amendment values-not only that of "checking" police excesses, but of facilitating the goal of enlightened citizen participation in local government.
Those who won our independence believed…that public discussion is a political duty; and that this should be a fundamental principle of American government. They recognized the risks to which all human institutions are subject.  相似文献
