An environmental assessment of the Canadian Nuclear Fuel Waste Disposal Concept was initiated in 1989. The primary purpose of the assessment is to determine the technical feasibility of burying nuclear-fuel waste deep into the Canadian Shield. If deemed acceptable, a second phase of facility siting will commence. The purpose of this paper is to evaluate the social and political dimensions of nuclear-fuel waste management in Canada. It is contended that nuclear-fuel waste management transcends technical concerns, and that the ultimate success or failure of siting procedures is hinged on social and political acceptability. Data focusing on various facets of a nuclear-fuel waste disposal facility were collected from a sample of residents from three northern Ontario communities. Results demonstrate that there is a strong relationship between facility acceptability, risk perception, and distance from community. On the basis of these findings, it is contended that a regional siting approach needs to be developed and implemented to ensure that concerns over the viability of nuclear power, equity, and trust are incorporated and granted legitimacy in the management of nuclear-fuel waste. Une évaluation environnementale du concept d'élimination des déchets de combustible nucléaire au Canada a débuté en 1989. L'idée première de cette évaluation est de déterminer la faisabilité d'enfouir les déchets de combustible nucléaire dans le Bouclier canadien. Si l'on estime que c'est possible, une deuxième phase dans le choix d'un emplacement d'enfouissement débutera. Le but de cet exposé est d'évaluer les dimensions sociale et politique qu'entraînent la gestion des déchets de combustible nucléaire au Canada. On dit que la gestion des déchets de combustible nucléaire va au-delà des préoccupations techniques et que le succès ou l'échec des procédures de choix d'emplacement dépendent aussi de l'acceptabilité sociale et politique. Les données portant sur différentes facettes d'élimination des déchets de combustible nucléaire ont été recueillies auprès de résidents sélectionnés dans trois communautés du nord de l'Ontario. Les résultats ont montré qu'il existait un lien très fort entre l'acceptabilité des installations, la perception de risque qu'elles entraînaient et la distance qui les en séparait de la communauté. Sur la base de ces constatations, on a avancé, quant au choix d'un emplacement, qu'il fallait envisager une approche sur le plan régional pour assurer qu'en matière de gestion des déchets de combustible nucléaire, on reconnaisse de manière légitime les préoccupations touchant à la viabilité de cette énergie.  相似文献

This paper advances the spatial-choice modelling literature by further examining the way in which spatial knowledge is gained. The specific research purpose of this paper is to see how a major boundary (the U.S.A.-Canada border) will affect the generation of a spatial-knowledge surface. It is accepted that an important impact on the way an individual makes a spatial choice, such as a decision to migrate, is the amount and quality of the information he / she possesses about different locations. A positive influence on such a knowledge surface is the population size of the location. Negative influences include the separating distance between individual and location, and the degree of clustering the location faces in respect to other places around it. This paper investigates the way in which these influences also hold if a major boundary lies between a subject and the investigated research space. The paper uses a multi-variate model calibrated on lists of recalled United States city names generated at 9 different Canadian test sites. These are then compared to similar model results from 22 U.S. test sites. The Canadian test results are more consistent than those for the United States. Also, for Canadian subjects, there is no distance decay in the probability of recalling a location unless the Canadian test site is located proximate to a major American border city. A strong relationship exists between the population size of the recalled location and its probability of being recalled. There is also further evidence to support a hierarchical method of knowledge processing, albeit in a weaker form than found in the U.S. test sites. Cet article contribue à la documentation sur la modélisation des choix spatiaux en analysant comment on acquiert des connaissances sur l'espace. Le but spécifique de la recherche est d'observer comment une frontière géographique (la frontière entre les États-Unis et le Canada) influencerait la génération d'une surface de connaissances spatiales. Lorsqu'un individu choisit un lieu d'une perspective spatiale (et lorsqu'on prend une décision de migrer) la quantité et la qualité des ren-seignements qu'on possède au sujet des différentes situations influencent profondément sa décision. La population d'un lieu a une influence positive sur une telle surface de connaissances. Parmi les influences négatives il y a la distance qui sépare l'individu du lieu dont il s'agit, la proximité de ce lieu aux autres et le degré d'agglomération d'un lieu par rapport aux autres dans les environs. Dans cet article nous essayons de déterminer comment ces influences fonctionnent si une frontière importante reste entre l'individu et l'espace qu'on étudie. Cette investigation utilise un modèle multivarié, calibré sur des listes de noms de villes aux Etats-Unis qu'on rappelle et qui furent générés à 9 sites canadiens différents. Nous faisons la comparaison entre ceux-ci et des résultats semblables des modèles de 22 sites aux Etats-Unis. Les résultats des tests au Canada sont plus uniformes que ceux des Etats-Unis. De plus, pour les canadiens la distance n'a aucune influence sur la probabilité de rappeler un lieu à moins que le lieu canadien ne se trouve pas très près d'une ville importante américaine située sur la frontière. Une relation forte existe entre la population d'un lieu rappelé et sa probabilité d'être rappelée. D'autres faits suggèrent également la validité d'une méthode hiérarchique de traitement des connaissances, même si ces indications sout moins fortes que ce que l'on observe aux sites américains.  相似文献

ABSTRACT. Responding to continuing discussions in this Journal regarding the importance of regional money supply and credit, a simple reduced-form regional money supply model is posited and an investigation of real regional money supplies is performed for several states around the country. Hypothesis tests are performed regarding the question of regional financial market segmentation, concluding that segmentation still exists in the United States. The empirical results also imply that interregional trade, presumably via the consequent constraint on regional banks, has at least as much effect on regional money supplies as Federal Reserve policies. These results lend further support for the assertion that regionally available money matters at the local level, and that regional analysis should continue to include regional money and credit as explanatory variables. The implications for policy makers are that: 1) national monetary policy cannot cure regional ills if the problems are manifested in regional industry mixes; and 2) some proposed banking reforms now being debated in Congress, i.e, nationwide branch banking and, particularly, industrial ownership of banks, are suspect. A healthy caution is warranted without more tests of these reforms.  相似文献

We measure the effect of resource‐sector dependence on long‐run income growth using the natural experiment of coal mining in 409 Appalachian counties selected for homogeneity. Using a panel data set (1970–2010), we find a one standard deviation increase in resource dependence is associated with 0.5–1 percentage point long‐run and a 0.2 percentage point short‐run decline in the annual growth rate of per capita personal income. We also measure the extent to which the resource curse operates through disincentives to education, and find significant effects, but this “education channel” explains less than 15 percent of the apparent curse.  相似文献

ABSTRACT. This paper applies the production-theory approach to assess the impact on domestic wages and employment of immigration to the United States. Inputs are disaggregated between recent immigrants, non-recent immigrants, native workers, and capital. Census cross-sectional data for 1980 and for 123 metropolitan areas are used. Empirical estimates are reported for alternative functional forms with special attention devoted to required curvature conditions which have frequently been violated in previous work. Elasticity estimates are reported for alternative settings, including for the short run where we view domestic factor prices as given and the long run where we treat them as flexible.  相似文献

The authors describe a complex of social, economic, and environmental problems on the Valaam Archipelago, associated with pollution of Lake Ladoga, heavy tourist pressure, and deteriorating residential/economic infrastructure for the small permanent population. The islands are known as the site of the architecturally and historically unique Monastery of the Transfiguration, situated on the main island of Valaam—now in disrepair from negligence, heavy visitor pressure, and use as residential quarters for all but a few permanent island residents. The option of resettling this population to the mainland is weighed against its comprehensive development as a historical and tourist center. translated by H. L.
