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

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

The organization of pupils in a boys' comprehensive high school into homogeneous teaching units in order to eliminate the psychological, social and academic effects of streaming by ability may be dysfunctional if the objectives of the institution include the attainment of higher verbal standards. A practising teacher identifies the establishment by pupils of a ‘verbal norm’, and describes the system of social sanctions imposed by the verbally less proficient against the above-average pupil.  相似文献

In this paper, we present and develop the argument that if the survival functions for two population subgroups converge in later life, a mortality crossover must precede the occurrence of this convergence. Specifically, two survival curves, S 1(x) and S 2(x), associated with two distinct population subgroups, G1 and G2, tend to converge before all members die out, as often observed and anticipated. This convergence leads to an increased mortality acceleration for the “advantaged” group, and eventually fosters the occurrence of a mortality crossover. We present a mathematical proof for this relationship and offer several explanations for the mechanisms involved in the process of survival convergence and the preceding mortality crossover. This new presentation demonstrates that mortality crossover is a highly observable demographic event given the trend of survival convergence in later life.  相似文献

We add to the global–local debate by highlighting concerns with the empirical and conceptual validity of the construct ‘integrated’ as it operates within corporate social responsibility (CSR). We do so by investigating the extent to which foreign national culture and related local issues are incorporated into the CSR policy of 37 multinational corporations, examining strategy development and implementation across global locations. This research suggests that integrated internationalization strategies do not resolve global and local CSR issues. In fact, they reinforce outcomes similar to global strategies, where core issues identified by headquarters are legitimated and local issues are marginalized, an outcome that appears somewhat at odds with the spirit of local responsiveness embedded in CSR thinking.  相似文献

This article uses privileged families who hire Independent Educational Consultants (IECs) as an instance to examine how privileged parents collaborate with individuals whom they consider educational experts to support their children in the college race. We argue that advantaged parents' anxieties about their children have created a market for IECs who provide expert advice in order to mitigate the uncertainties that these parents experience and to manage various goals that they want to achieve at an important turning point in their children's lives. Drawing primarily on interviews with parents who work with IECs, we introduce the concept of “collaborative cultivation” to analyze the processes whereby advantaged parents rely on the expertise and expert status of private counselors to cope with their and their children's vulnerability in the college race while at the same time preparing their children for the unknown future. The parental method of “concerted cultivation” reveals how elite parents rely on individuals they perceive as experts to establish “bridges” between their own social worlds and the academic worlds that appear to beyond their control. This bridging labor points to the myriad cultural beliefs enacted to justify the child‐rearing goals that privileged parents wish to accomplish by working with IECs.  相似文献
