Across the OECD, Canada??s record on CO2 emissions is particularly poor, with overall emissions up 32% over the 1990?C2007 period. The current paper seeks to better understand this situation by making systematic comparisons of Canada with other OECD countries. For Canada overall, the rapid increase in emissions over the 1990?C2007 period can be explained by several factors, including major population growth, increased affluence (although to a lesser extent than elsewhere in the OECD), a continued dependence on fossil fuels, while continuing to increase its overall demand for energy. While the energy intensity of Canada??s economy has declined somewhat over recent years, it actually lagged behind most OECD countries on this front and remains one of the most energy intense economies in the world (2nd highest in the OECD on our indicator of energy intensity). While there are many factors responsible for this, Canada??s particularly energy-intensive industrial structure is certainly relevant, as is the importance of its primary sector relative to most developed nations.  相似文献

This paper reports the results of an empirical study investigating people’s preferences over three different types of perturbation to their survival function, each perturbation generating the same gain in life expectancy. Preferences over the three different perturbations were found to be distributed more or less evenly across the subject pool. Use of a novel experimental methodology generated economically consistent and intuitively plausible responses to (necessarily) hypothetical questions concerning improvements in life expectancy by first allowing respondents to gain experience while making similar choices in an incentivized setting involving financial risk. The results demonstrate the potential for economic experiments to contribute to the development of more robust methods for policy evaluation in domains where physical risk is an important factor.  相似文献

This article is based on a series of interviews with small business owners and managers concerned with problems of growth. There is an abundance of literature which describes the processes of evolution in business, but much of it describes the end product of growth rather than the initial problems incurred in the embryonic stages of corporate development. This article uses the experience of several small companies to suggest a model of development for the small firm. These companies range in size from $1m to over $100m. Each company faces significant problems as it copes with the pressures of growth.  相似文献

Unlike other marginalised groups children are often not in a position to enter into dialogue with adults about their community needs and environmental concerns. Despite the current emphasis on involving communities in the regeneration of their own neighbourhoods, young people are still seemingly invisible in decision‐making processes. This paper looks at recent attempts to increase public participation in local decision‐making, proposes a typology of community action that recognises the different ways in which children may be drawn into the process of neighbourhood renewal and offers a set of recommendations that, if taken up, provide an agenda that will strengthen the active social commitment of young people in general.

With this issue, we are initiating a section for notes and commentaries, to which contributions are invited. It is our hope that this section will serve an important purpose in permitting our contributors to publish brief reports, notes on research, commentaries, and other short items of a scholarly nature which do not ordinarily fit within the framework of an article .—T he E ditors  相似文献

Summary An age-structured population model is used as a vehicle for presenting a method for the analysis of interactions between pairs of insect pest control methods. This analysis is based on partitioning the total mortality acting on a population into its constituent components from all known sources. Pairwise critical mortality curves are then constructed which represent the combined mortality required for eradicating the pest population. Effort curves are then constructed from computing the mortality resulting from a given amount of control effort. The convolution of the critical mortality curves and the effort curves then yields the isoclines formed by the effort required of two control methods in combination to achieve eradication. This analysis allows the prediction of either synergism or interference between the control methods and also helps explain patterns observed in previous modelling of such combinations of pest control methods.  相似文献

Recent studies project that most new U.S. workers by the year 2000 will be minorities, and warn that educational deficiencies among blacks and Hispanics may lead to a two-tiered society. Since the 1960s the U.S. government, prodded by a coalition of black and Hispanic rights organizations, has adopted a minority-discrimination model of equal opportunity that requires affirmative-action benefits for both protected groups to compensate for past discrimination. For Hispanics these programs have required separate, Spanish-language instruction in school.Since 1969, the availability of new survey data on ethnicity, family income, and Englishlanguage proficiency from the Census Bureau and the National Assessment for Educational Progress has permitted comparisons of social mobility by racial and ethnic groups. These studies show greater economic success among nonEnglish-speaking groups from Europe and Asia than among white-Anglo-Saxon-Protestant (WASP) groups, and they show similar upward mobility among Hispanics when proficiency in English is taken into account.These optimistic trends are tempered by the demands of the new global economy for high levels of literacy and numeracy in the knowledge-based industries of the future. In this job competition Asian-Americans, despite their language difficulties, have been most successful and blacks least successful. The political and ideological needs of black and Hispanic leaders have tied government policies to the minority-discrimination model and linked Hispanic remedies to Spanish-language programs, but the empirical data associate economic success with the acculturation model and English-language proficiency.  相似文献

The ‘individual’ forms of industrial conflict, such as absenteeism, have received little attention in industrial sociology. This paper attempts to correct this deficiency by attacking the conventional approach to these phenomena and by using recent research findings to develop a sociological alternative. The main characteristics of the conventional approach are the focus on absenteeism without reference to the patterns of work relations of which it is part, and a treatment of it as a ‘problem’ which requires a remedy. The weakness of the approach is that neither the social meaning of absence nor the structural context of work organization is investigated. The alternative approach examines absence as part of a set of workplace relations and is thus able to explore how far, in what ways, and with what consequences it represents a form of conflict. In combination with other recent studies of the links between absence and the contingencies of individual workers' situations, a more adequate sociological treatment is possible. This approach is, ironically, better able to grasp the managerial problem of absence and workplace control than is the ‘managerialist’ conventional approach.  相似文献
