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

Suicides or suicide attempts with power saws (band, circular or chain saws) are rather rare events and only a few case reports exist in the forensic literature. The use of a band saw, in particular, has been extremely rare in cases of suicide.We report two cases of suicide that occurred in the same suburban area, three years apart. In each case, the victim was a carpenter and had a history of psychiatric disorder and/or of prior suicide attempts.We summarize the findings of the death scene investigations, the pertinent autopsy findings, and also summarize the world literature pertaining to suicide committed with power saws. 相似文献

In the face of an unprecedented surge in United Nations (UN) peacekeeping activity over the past three years—with now almost 100,000 military, police and civilian personnel deployed on four continents in 18 operations—there is a need for the UN to develop a comprehensive doctrine that better defines what modern UN peacekeeping has become and that covers the full range of civilian peacebuilding activities that are now a standard feature of Security Council mandates. This paper serves as a primer and proposes an agenda for debate on such a doctrine. It summarises evolutions in thinking and practice over the past 15 years. It also highlights key conceptual challenges and political fault lines to be reconciled in order for a new comprehensive doctrine to enjoy broad support of the UN's 192 Member States, while still providing relevant guidance to thousands of personnel on the front-lines of the effort to help rebuild war-torn states. 相似文献

Industries can be classified into fixprice sectors according to their pricing behaviour. Although Hicks and Morishima have broadly classified manufacturing industries into fixprice and the rest of the economy into flexprice, using cost-based input-output models, the present paper reclassifies Malaysian agrobased manufacturing into flexprice and nonagrobased manufacturing into fixprice categories. By compiling annual sectoral price indices, both for intermediate and primary inputs, the model estimates sectoral residual profits of 1978 and 1983 vintage technologies. 相似文献

Nine Y-STR loci from the "minimal haplotype" (DYS19, DYS385a/b, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393) included in Y-STR Haplotype Reference Databases (YHRD) with 4 additional Y-STRs (DYS436, DYS437, DYS438, DYS439) were analyzed by PCR using duplex and Y-PLEX 12 kit, followed by automatic genotyping in a sample of 105 Tunisian males originating from Sfax region (south Tunisia). Allelic frequencies and gene diversities for each Y-STR locus were determined. The high haplotype diversity (0.9932) and discrimination capacity (0.7714) show the usefulness of these loci for human identification in forensic studies and paternity tests in Tunisia. The most common haplotype was shared by 4.7% (5 individuals) of the sample was only found in samples from the Tunisian population reported in YHRD. One private allele for DYS392 (allele 17) was discovered and duplications were observed for five loci (DYS19, DYS389I, DYS393, DYS437 and DYS439). 相似文献

Feminism, including in particular such notions as women's right to equality and their right to control their own lives, is, with respect to the Middle East's current civilization at any rate, an idea that did not arise indigenously, but that came to the Middle Eastern societies from ‘outside’. To predict and direct the future of that idea, and therefore the future of women in the Middle East—if this is indeed at all possible—an understanding of the development of feminism in the Middle East is crucial, including its transformations transplanted to a Middle Eastern, predominantly Islamic environment, and its different interpretations in the locally different cultures of the Middle East. It swiftly becomes apparent, in considering the history of feminism in the Middle East, that two forces in particular within Middle Eastern societies modify—hampering or aiding—the progress of feminism. First there are attitudes within the particular society, and the culture's and the sub-culture's formulations, formal and informal, regarding women. Second and perhaps as important, are the society's attitudes and relationship to feminism's civilization of origin, the Western world. Since the late nineteenth century, when feminist ideas first began to gain currency in the Middle East, a Middle Eastern society's formal stand on the position of women has often been perhaps the most sensitive index of the society's attitude to the West—its openness to, or its rejection of Western civilization. Thus Turkey's attitude of openness to Western civilization at the beginning of this century (with which this study begins) was epitomized by the abolition of the veil. More recently, the veiling of women in Iran has constituted perhaps the chief index and deliberately chosen symbol of Iran's rejection of Western civilization. The present article is the first of a series in which I will be exploring aspects of feminism in the Middle East. 相似文献
