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

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

In the late nineteenth and early twentieth centuries, many Americanhistorians decided that the accounts by which people in theUnited States understood their past were unrealistic, subjectto romantic distortions, and chauvinistic. Even though somestories were well intentioned, they were false and must be rejected.One well-known example is Parson Weems' story of George Washingtonas a boy cutting down the cherry tree and, when questioned byhis father, saying, "I cannot tell a lie." In the process of"realistic" reinterpretation and muckraking, however, thesehistorians threw out many real babies with the surplus of romanticbath water. A case in point is the tradition of federalism thatshaped American history, permeated the experience of the menwho wrote the United States Constitution, and underlay everyfacet of our social order. The so-called "realists" went toofar and tossed out an important part of the reality that isAmerica. Can the federal tradition be recovered and placed againat the focus of American political thought, or is it a losttradition?  相似文献

Numerous studies have established a strong connection between the use of illicit drugs and the commission of other illegal activities, including both predatory and property crimes. No study, however, has examined the cost of crimes associated with drug users both as victims and as perpetrators. In the present study, recent data were analyzed from a targeted sample of chronic drug users (CDUs) and a matched sample of non-drug users (NDUs) in Miami-Dade County, Florida, to estimate the incremental cost of crime associated with CDU. Two separate models were employed to estimate (1) the probability of being a victim or a perpetrator of crime and (2) the cost of crime for both situations. The cost measures were transformed to reduce the influence of extreme outliers, and a smearing technique was used to compare the cost of crime for CDUs relative to NDUs. The findings illustrate that criminal activity among CDUs is circular, extensive, and costly. Implications for law enforcement, criminal justice policy, and substance abuse treatment are discussed.  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

This research examines in detail the structure of the issue public for health care reform, drawing from extensive, nationally representative survey data tapping general attentiveness to news and public affairs, specific interests in health care issues, and motivations (e.g., personal health and financial conditions) to follow health care reform issues. We furthermore adopt a multi-dimensional approach to defining the contours of the issue public for health care policy, separately studying its cognitive, affective, and behavioral underpinnings. Results indicate only weak interconnections across these dimensions—measured through health care knowledge, holding strong opinions on health care issues, and participation in health-related political activities, respectively—and somewhat different structural and motivational patterns underlying each. Theoretical, conceptual and methodological implications of these findings are discussed.Vincent Price and Joseph N. Cappella are Professors in the Annenberg School for Communication at the University of Pennsylvania, where Clarissa David, Brian Goldthorpe, and Marci McCoy Roth are doctoral students. Gathering of the data reported here was supported by grants to Vincent Price and Joseph N. Cappella from The National Science Foundation (Grant EIA-0306801) and the Annenberg Public Policy Center of the University of Pennsylvania. Views expressed are those of the authors alone and do not necessarily reflect opinions of the sponsoring agencies.  相似文献

The purpose of this study was to examine whether gender differences exist in the rate, type, and general predictors of recidivism for nonviolent offenders. A total of 328 male and female Texas state jail offenders were matched on current offense, total number of arrests, age, and race. Contrary to previous findings, the results demonstrated no significant gender differences for recidivism rates, although significant gender differences were found for those who had reoffended with property and prostitution offenses. Similar to previous findings, age and total arrests were significant predictors for both male and female offenders. In the current sample, substance abuse was predictive for male offenders only. Although no gender differences were found across the recidivism predictors of static and criminogenic need, the protective factors of positive social support significantly predicted recidivism for female offenders and not male offenders. The current results add to the understanding of gender differences for the assessment, risk prediction, and treatment of offenders.  相似文献
