The indivisibility of Canada's national and international political and economic interests is recognized. These interests can be furthered only if the interdependence of economic, social and political considerations are expressed through clear cut national policy goals for integrating rural and urban interests. These goals in themselves are meaningless without the requisite government authority backed up by resources and personnel for the implementation process. An integral part of implementation is the need to ensure participation of the resident population in development goal setting and implementation of programs. Current international experience supporting the need for local residents to be so involved are presented. L'AIDE AU DÉVELOPPEMENT AGRICOLE: L'indivisibilité des intérêts économiques et politiques du Canada au niveau national et international est déjà reconnue. Ces intérêts peuvent être favoriser seulement si l'interdépendance des considérations économiques, sociales et politiques sont exprimées à trovers une politique nationals précise afin d'intégrer les intérêts rurals et urbains. Ces ambitions sont en eux-mêmes sans signification, sans l'autoritée gouvernementale secondée par les ressources et le personnel pour un meilleur développement. Une partie intégrante de ce développement sera le besoin d'assurer la participation de la population résidante dans un cadre de croissance. Les expériences courantes, supportant le besoin des résidents locaux àêtre engager, sont présentées.  相似文献

The world's subsurface space, including Britain's, is already used in a variety of ways, ranging from occupancy to disposal and the bulk storage of materials and fuels. In the future it is likely that it will be put to further use in response to trends in technology, resource supply and demand, socioeconomics and geopolitics. Here the present and future uses of underground space, and the potential planning and social issues affecting its development, are reviewed. Future uses are likely to be in the area of increasing occupancy (both commercial and residential), the secure storage of documents and data, the storage of carbon dioxide for carbon abatement, natural gas, compressed air stores of energy from traditional and renewable sources, the use of underground heat in buildings and the proposed deep geological disposal of radioactive waste. The article will also explore pressure points and challenges. These will include the regulation of multiple uses of subsurface storage space and, for projects of national importance including natural gas and radioactive waste storage, legislation to lessen the effect of local opposition relative to the ‘national need’. This article does not discuss future mining, hydrocarbon extraction, or water resources.  相似文献

The purpose of this study was explore the body image experiences of women who play tackle football. Data included semi-structured interviews with 15 players on a women's tackle football team in Western Canada. Data were analyzed thematically and objectification theory was used to interpret the findings. Themes that emerged included: a) improved body image through physical change, appreciation of function over appearance and shifting ideals of beauty; b) importance of a social atmosphere that celebrated diverse bodies; and c) negotiation of body image on and off the field. Research has documented a connection between body image and physically active leisure, but much about the nature of the relationship is still unclear. The findings of this study provide insight into elements of physically active leisure (e.g., social atmosphere or nature of the activity) which can be used to promote positive body image, health, and wellness in leisure settings.  相似文献

Small business economics   总被引:16,自引:0,他引:16  
The paper presents an overview of small-business economics. Small businesses are shown to comprise a substantial and expanding segment of the U.S. economy. The role of small businesses in the economy is considered from the standpoint of various economic theories of the size distribution of firms. Firm-size related empirical regularities are reviewed and their implications for economic theory is discussed. Several small-business policy issues are discussed, including the role of small businesses in labor, macroeconomic, and regulatory policies, along with a review of research on small-business economics that might help guide these policies.We wish to thank Zoltan J. Acs and an anonymous reviewer for helpful comments.  相似文献

The purpose of this study is to build on the results recently obtained by Poznanski (1990). First, the estimation technique is generalised by removing both the symmetric restrictions and the effects of autocorrelated errors that are present in simple logistic functions. Secondly, attention is drawn to the existence and consequences of multicollinearity when non linear techniques are applied to a general exponential. Thirdly, an attempt is made to quantify the importance of market structure and time lags in adoption as determinants of diffusion speed. Finally, a comparison between these generalised results and Poznanski's is made.The study concludes that, by generalising the estimation technique, some significant changes take place. Changes occur in the ordering and magnitude of diffusion speeds, especially amongst the developing and centrally planned economies. Changes also occur in the nature of the diffusion process, and in the importance attributed to market structure and diffusion lags in determining the rate of diffusion. It is also shown that, for some countries, multicollinearity imposes constraints on the type of generality that can be obtained.  相似文献

A new test for additive heteroscedasticity in the disturbances of the linear regression model is proposed. Power functions of various forms of the new test are compared empirically with those of currently favoured tests for a range of heteroscedastic models. The results highlight the power advantage of a test which is MP1 at a central point in the alternative hypothesis parameter space. The main conclusion is that the recommended version of the new test is generally more powerful than existing tests against medium and severe heteroscedasticity, whereas the King and Szroeter tests perform better against weak heteroscedasticity.  相似文献

The objective of this paper is to set a framework for examining the conditions under which a research university becomes more than a latent asset [Power, D., and A. Malmberg. 2008. The contribution of universities to innovation and economic development: In what sense a regional problem? Cambridge Journal of Regions, Economy and Society 1, no. 2: 233–46.] in regional economies. The framework is comprised of four propositions used to identify drivers of change, evidence of change and evidence of impact. As an exemplar, we examine the University of Oxford's growing engagement in its local region. This paper shows that the convergence between the interests of the university and the local high-tech economy is particularly associated with broader technological trends and with the University's capacity to draw on national funding programmes designed to stimulate ‘third-stream’ activities, including entrepreneurship courses and regional networking activities.  相似文献
