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: Although the ability to develop latent fingerprints on paper using heat alone has been noted previously, it has been considered impractical for casework and inferior to other techniques. Here a new refinement of the technique is demonstrated for the high quality development of latent fingerprints on porous surfaces such as paper. Fingerprints deposited on various papers were developed by exposing them to hot air with a temperature in the vicinity of 300°C, for periods of c. 10–20 sec. Several different heating methods were tested. The novel observation was made that after shorter heating times, fluorescent prints could be observed. These became visible after longer heating times, as noted by earlier workers, but with greatly improved contrast compared with their results. Prints from various donors (and aged prints) were developed with excellent ridge contrast. Direct heating methods (such as with a hot plate or press) produced inferior results. The refined technique, which is simple, safe and inexpensive compared with conventional methods, has great potential for use in forensic laboratories. 相似文献

Relatively few studies have assessed theoretically relevant predictors of individual’s perceptions of racial profiling by law enforcement officers. The current study addresses this limitation by drawing on theoretical frameworks highlighted in the growing body of literature examining disproportionate minority contact (DMC) with the criminal justice system. Specifically, we draw on the racial and symbolic threat perspectives with the objective of identifying theoretically relevant individual and community level predictors of perceptions of racial profiling by public and private police bodies in airports, malls, and on the roads. Results of our analysis of data on White and Black individuals nested within communities support the racial threat perspective in documenting the influence of racial heterogeneity and interracial labor market competition on perceptions of racial profiling. However, in contention to predictions derived from the symbolic threat perspective, the results fail to uncover a link between interracial socioeconomic inequality and perceptions of racial profiling by law enforcement officers. These results highlight the importance of moving beyond individual explanations of profiling and other forms of DMC and suggest community characteristics and perceptions of intergroup threat are particularly salient to understanding perceptions of race-based distinctions in formal social control. 相似文献

The issue of hate speech has received significant attention from legal scholars and philosophers alike. But the vast majority of this attention has been focused on presenting and critically evaluating arguments for and against hate speech bans as opposed to the prior task of conceptually analysing the term ‘hate speech’ itself. This two-part article aims to put right that imbalance. It goes beyond legal texts and judgements and beyond the legal concept hate speech in an attempt to understand the general concept hate speech. And it does so using a range of well-known methods of conceptual analysis that are distinctive of analytic philosophy. One of its main aims is to explode the myth that emotions, feelings, or attitudes of hate or hatred are part of the essential nature of hate speech. It also argues that hate speech is best conceived as a family resemblances concept. One important implication is that when looking at the full range of ways of combating hate speech, including but not limited to the use of criminal law, there is every reason to embrace an understanding of hate speech as a heterogeneous collection of expressive phenomena. Another is that it would be unsound to reject hate speech laws on the premise that they are effectively in the business of criminalising emotions, feelings, or attitudes of hate or hatred. 相似文献

As technology with surveillance capacities has advanced, the debate over the rights of the citizenry to be free from governmental breaches of personal privacy has intensified. Within the United States, government actions legally challenged as intrusions into personal privacy have been analyzed under the Fourth Amendment, but Supreme Court rulings in such cases lack a clear and consistent rationale. Additionally, while more than a dozen federal privacy statutes have been enacted, each piece of legislation pertains to a specific type of information (e.g. driver’s license information, education records, and financial records). There is no overarching federal legislation which protects the individual’s private affairs from warrantless government inspection. A key issue underlying the scope of the debate and the variation in court decisions and public policies pertinent to invasions of privacy by government agencies is the lack of a clear and cogent definition of ‘privacy.’ By means of a review of the evolution of legal protections of privacy under the Fourth Amendment and a review of the evolution of technology with surveillance applications, it is suggested that there is a need for a sound operational definition of privacy. As a starting point for an informed and pragmatic dialogue on this matter, an operational definition of privacy built upon extant case and statutory law is provided. 相似文献

The Institute for Community Peace has conducted two demonstration projects to determine whether communities can be engaged to prevent violence as it is identified and defined locally and link primary prevention across multiple forms of violence. The projects present evidence that community engagement can effect primary violence prevention; the violence prevention field has much to learn about developing and sustaining strategies to address interrelated violence problems; and the violence prevention field and community residents are in vastly different places with respect to primary violence prevention. 相似文献

Since 1815 it has been generally understood that the Great Powers acting in concert have some responsibility for ensuring/underwriting order and stability within international society—although it is clear that only occasionally have they actually discharged this responsibility. Contemporary conditions, where there is only one superpower, change the situation radically; the United States may be able to take the lead in organising the provision of global public goods such as an open global economy and a secure strategic environment, but it also may possess the capacity to promote its own particular conception of the good in the world— the conservatism characteristic of a concert of Powers may not dominate the actions of a single superpower. However, changes in the nature of "power' ' in an age of globalisation and "Empire'' may actually limit the capacity of any actor, or collection of actors, to discharge its responsibilities. 相似文献
