The 750 page report,The State of Canada's Environment, is the collaborative effort of more than 100 experts from universities, private industry, environmental groups, and government. In 27 chapters the report addresses four fundamental questions about Canada's environment: what are the key environmental conditions and trends in Canada; what are the links between human activities and environmental changes; what are the environmental, economic, and health implications of these changes; and what are Canadians doing to address the concerns identified? Topics examined include: environmental components (air, fresh and marine water, land, and wildlife), human activities that affect the environment (e.g. forestry, agriculture, fisheries, urbanization), as well as six regional case studies and major environmental issues such as toxic chemicals, ozone depletion and acid rain. The report also indicates areas where Canadians have made progress toward sustainable development and identifies areas where work remains to be done. Actions that are being taken to strengthen state of the environment reporting in Canada, including the development of indicators, are also briefly discussed.  相似文献

The development and initial psychometric properties of an adolescent gambling problem severity measure are described. The scale, based on a revision of the South Oaks Gambling Screen (Lesieur & Blume, 1987), was administered to 1,101 older (ages 15 to 18) Minnesota adolescents as part of a state-wide gambling survey. Study results indicated that the scale had moderate internal consistency reliability and was significantly related to alternate measures of problem severity for male subjects. Because the rate and severity of gambling among females was very low, the psychometric adequacy of the scale for females is not known at this time. The implications of study findings to the conceptual understanding of adolescent gambling problem severity as well as study limitations and future research needs, are discussed.Support for the study was provided by the Minnesota Department of Human Services and the Center for Addiction Studies, University of Minnesota, Duluth. The authors gratefully acknowledge the assistance from Robert Blum, Linda Harris, Durand Jacobs, J. Laundergan, Alan Mathiason, Brenda Miller, James Schaefer, school officials from the participating high schools, and interviewers who assisted with the telephone survey.  相似文献

We employed 4,095 couples from both waves of the National Survey of Families and Households (NSFH) to test a model of couple violence drawn from several theoretical perspectives. The outcome distinguishes among nonviolent couples and those experiencing either physical aggression or intense male violence. According to the model, background characteristics of couples are related to relationship stressors, which affect the risk of violence via their tendency to promote verbal conflict. Considerable support for the model was found. Couples were at higher risk for one or both forms of violence if they were younger at union inception, had been together for less time, were both in their first union, had only one partner who was employed, had a nontraditional woman paired with a traditional man, had at least one partner who abused substances, had more children, had more frequent disagreements, exhibited a more hostile disagreement style, or lived in an economically disadvantaged neighborhood. Moreover, the effects of stressors such as the number of children and couples' employment status disparities appear to be mediated by disagreement frequency and disagreement style.  相似文献

Plummer  Ken 《Qualitative sociology》2003,26(4):515-530
This article reflects on the linkage between developments in symbolic interactionist theory over the past thirty years and the sociological study of the social construction of sexualities. After some personal reflections on the development of the theory, four main themes are highlighted: the links to postmodernism and queer theory; the paths to new research styles; some internal problems with the theory; and the need to reinstall the importance of the body. The article concludes that symbolic interactionism remains a major approach to the study of sexuality.  相似文献

Unions,PAC contributions,and the NAFTA vote   总被引:1,自引:0,他引:1  
Political action committees (PACs), especially those controlled by organized labor and business, have been shown to affect Congressional voting. We explore how PACs influenced the House of Representatives’ vote on the North American Free Trade Agreement (NAFTA). The NAFTA vote is analyzed because organized labor strongly opposed the treaty while business generally supported it and because of the straight-forward voting generated by its fast-track status. Probit analysis of a unique, unpublished data set containing information about PAC and non-PAC contributions to the 1992 House election campaigns demonstrates that Representatives who depended largely on labor PACs tended to oppose NAFTA, while Representatives who derived a large proportion of their campaign contributions from business PACs tended to favor its passage.  相似文献

Recent studies have attempted to understand the processes involved in joint attention because of its relevance to both atypical and normal development. Data from a recent study of young children with autism suggests that performance on a delay nonmatch to sample (DNMS) task associated with ventromedial prefrontal functions, but not an A‐not‐B/delayed response task associated with dorsolateral prefrontal cortex, was related to joint attention skills (Dawson et al., 2002). Recent research also suggests that joint attention is associated with dorsalmedial brain systems linked to self‐monitoring (Mundy, 2003). This study investigated the relations among joint attention, DNMS, and self‐recognition performance in a longitudinal study of 39 normally developing toddlers from 14 to 18 months. The results indicated that development on the DNMS and self‐recognition tasks, but not a means end task, predicted joint attention at 18 months. Further analysis showed that the model was only significant for initiating joint attention (IJA). The implications of these results for the neuro‐development of IJA are discussed.  相似文献

The iron law of oligarchy is applied to the VFW. Using participant observation and qualitative interviews, membership of the VFW is dichotomized into a leadership oligarchy and a drinking membership. Opinions of members of the two groups about the purposes of the organization and about each other are documented. An historical analysis traces the change in organizational goals over time from promoting nationalism, fraternalism, and special benefits for members to political advocacy of veterans' rights.  相似文献

全球文化秩序长期以来都被西方发达国家的媒介所主导,其突出表现在媒介与传播资源从西方发达国家向欠发达国家的单向流动,从而在某些欠发达国家形成主导地位,文化殖民成为可能.随着时代的发展与变化,媒介资源流动方向由单向发展为多向,媒介的应用背景随之改变,在全球化背景下的重新评估也成为必然.本文透过不同市场受众对于媒介产品的反应,以及发达与欠发达国家在媒介产品内容模式上的发展与更新两个角度,分析文化殖民主义下的主导媒介与“逆流”媒介两股势力之间的对立以及相互作用的关系,并从中总结出全球媒介产品发展与更新的趋势.  相似文献
