UNRAVELLING THE POPULATION TURNAROUND IN RURAL CANADA   总被引:1,自引:0,他引:1  
This paper attempts to unravel the rural population turnaround in Canada through a disaggregation and analysis of rural growth rates by (1) two decades, 1961–71 and 1971–81, (2) the farm and non-farm components of rural population, (3) provincially based regions, and (4) area types based on proximity to urban centres. Following a discussion of the various definitional and boundary-matching issues arising from the use of the Census of Canada, results are presented in tabular and map form. Although rural growth rates did in all likelihood exceed urban rates in the 1970s, the extent of this turnaround is undoubtedly exaggerated in the census data, primarily because of definitional and reclassification effects. Moreover, setting aside data-related anomalies, there is strong evidence that much of this rural population growth was in fact ‘spillover’ from urban centres. Cet essai traite du virage pris par la population rurale au Canada au moyen d'une décomposition et d'une analyse des taux de croissance rurale où interviennent(1) les deux décennies 1961–71 et 197 1–81, (2) les com-posantes agricoles et non-agricoles de la population rurale, (3) les régions définies sur une base provinciale, et (4) les types de zones établies à partir de la proximité par rapport aux centres urbains. Les problèmes de définition et de démarcation d'aires comparables soulevés par I'utilisation des données du Recensement du Canada sont abordés en premier lieu. Puis, les résultats sont présentés sous forme de cartes et de tableaux. Bien que les taux de croissance rurale aient, selon toute vraisemblance, dépassé les taux urbains dans les années 70, I'ampleur de ce virage réulte sans doute d'exagérations dans les données du recensement, prin-cipalement attribuables aux effets de délimitation et de reclassification. De plus, mises à part les anomalies relatives aux données, il y ade bonnes raisons de croire que cette croissance de la population rurale provient en grande partie du décongestionnement des centres urbains.  相似文献

This article reports a generalised and systematic approach to the thermoluminescence (TL) dating of samples which suffer from anomalous fading. We hypothesise that the TL signal from each mineral phase is composed of a stable and an unstable portion. The decay of the unstable TL is accelerated thermally, until only stable TL remains. The dating is then carried out on this stable signal. The results, on four known-age, coeval samples, exhibiting gross anomalous fading (25-50% loss over a few days), indicate that many, if not all, samples may successfully be dated with this approach.  相似文献

WORDSWORTH and LAKE DISTRICT TOURISM: ROMANTIC RESHAPING OF LANDSCAPE   总被引:1,自引:0,他引:1  
Creative literature colours popular perception of landscape and place. An analysis of English romanticism, Wordsworth's poetry in particular, illustrates how the transformation of an actual landscape into a literary landscape helped change attitudes toward wilderness and natural beauty. The romantic ideology fostered impressions of an idyllic, untamed eden. In response to public fascination with this mythologized and emotional portrait of place, a tourist landscape emerged. Thus even those unfamiliar with romantic literature are encouraged to see particular landscapes from a literary perspective.
Dans la formation d'une perception envers un paysage ou un endroit, un élément important est souvent la littérature imaginaire. Une analyse du romantisme anglais, en particulier la poésie de Wordsworth, démontre comment la transformation d'un paysage actuel sous une forme littéraire contribua fortement à un changement d'attitude envers la nature. Cette idéologie romantique encouragea la notion d'un jardin d'Eden encore sau-vage. la fascination entretenue par ce portrait mythique créa finalement un environnement touristique. Même ceux qui n'ont guère connaissance en littérature romantique ont une vision d'un paysage particulier qui dérive dune perception littéraire.  相似文献

ABSTRACT. This paper uses a two-stage hedonic wage approach to derive the benefits from improvement of five cultural amenities. It is argued that the hedonic approach permits valuation of both private and local public aspects of cultural goods since access to the amenity is an essential input in the production of the final service flow. Empirical estimates of willingness to pay suggest price and income elasticities are approximately unity. Lower-bound estimates of marginal benefits for a representative city range from $0.85 million for an additional theater to $57.9 million for an additional zoo facility.  相似文献

ABSTRACT. The distribution of above-median income groups can be described accurately by OLS regression of the Pareto distribution. The excellent fit of log-linear regression has led some researchers to conclude that extrapolated income measures in the open end of the distribution are reliable. The analysis of income distribution data for metropolitan areas reveals: (1) that OLS tends to consistently overestimate the number of families in the tail, and (2) that the overestimation can have serious implications for hypothesis testing.  相似文献

ABSTRACT This paper investigates the implication of production-technology uncertainty for the exclusion theorem. The paper presents the result that the risk-averse firm facing production technology uncertainty prefers an intermediate location to avoid risk under certain conditions. The firm chooses an intermediate location (over a corner location) particularly if its degree of risk aversion overwhelms the inherent convexity of profit with respect to location. The latter depends, in turn, on the structure of production technology characterized by the elasticity of substitution and returns to scale parameters.  相似文献

ABSTRACT The origins and development of the network equilibrium problem are traced and interrelated. Two principal formulations are considered the network equilibrium problem with variable travel demand, and the combined model of trip distribution and traffic assignment. The relation of these models to subsequent developments concerning mode choice, residential location, estimation of origin-destination tables from link flows and stochastic route choice are then reviewed.  相似文献

ABSTRACT This paper examines the role of the structure of transportation rates in the Weber-Moses triangle model. It shows that, in Zeigler's analysis, the appearance of the price elasticities of demand for inputs actually vanish by a simple application of the envelope theorem. Applying comparative statics analysis, we show when transportation rates are a function of quantity and distance, the assumptions that the production function is homogeneous of degree one and the transportation rates elasticities with respect to quantity and distance are constant are not sufficient to insure that the optimum location is independent of the level of output. This result is significantly different from that obtained by either Miller and Jensen or Zeigler.  相似文献
