The geography of the Canadian economy has long been dominated by heartland‐hinterland contrasts, with manufacturing identified as the dominant function of most heartland cities in analyses of the 1961 and 1971 census data. However, the proportion of employment in manufacturing has been declining in the heartland provinces of Ontario and Quebec over the past fifty years and some geographers argue that the heartland‐hinterland dimension of the regional economy is being overridden by city‐regions that are integrated into global networks of production and trade. The heartland‐hinterland trends are examined using multifactor partitioning (MFP), an advanced shift‐share methodology, for the period of 2001–2006. This is the first intercensal period in which Canadian business has faced the full impact of the removal of North American tariff protection and the increased globalization of the Canadian economy. The data covers employment by eighteen industry sectors for the seventy‐three economic regions defined by Statistics Canada. MFP measures the region and industry‐mix effects, which are interpreted as in the traditional shift‐share model (though they are derived more accurately) and, in addition, an interaction effect. The results demonstrate that the broad heartland‐hinterland differences in the distribution of population and employment growth are increasing not decreasing and that the hinterland is in fact falling further behind the heartland in employment growth. However the Calgary‐Edmonton corridor and the Lower Mainland of British Columbia are emerging as a western heartland. The population size of cities does affect their rates of employment growth, but so too does their location: the growth of heartland cities is outpacing those in the hinterland. The Appendix provides the equations for two‐variable multifactor partitioning.  相似文献

Changing Perspectives – From the Experimental to the Technological Turn in History and Philosophy of Science. In the 1960s the philosophy of science was transformed through the encounter with the history of science, resulting in a collaborative venture by the name of “History and Philosophy of Science” (HPS). Philosophy of science adopted ever more regularly the format of the case study to reconstruct certain episodes from the history of science, and historians were mostly interested in the production of scientific knowledge. The so‐called “experimental turn” of the 1980s owed to this interaction between philosophy and history. Its guiding question remained quite traditional, however, namely “How do the sciences achieve an agreement between representation and reality?” Only the answers to this question broke with tradition by focusing not on theory but on the role of instruments and experiments. – Roughly 30 years after the experimental turn, another transformative encounter appears to be taking place. HPS is being transformed in the encounter with philosophy of technology. From the point of view of philosophy of technology, the question does not arise whether and how the agreement of mind and world, representation and reality can be achieved. When things are constructed, built or made, human thinking and physical materiality are inseparably intertwined. Instead of seeking to describe a mind‐independent reality, technoscientific researchers are working to acquire and demonstrate capabilities of experimental or predictive control. When science is regarded as a kind of technology, a program of study opens up for epistemology and so do avenues for the historiography of science. History of science might now show how the problems and procedures of the sciences arise from and impinge back upon a world that is itself a product of science and technology. It thereby abandons its traditional HPS niche existence and joins forces with environmental history, history of technology, social, labor, and consumer history.  相似文献

The fish remains sampled from archaeological sites are generally the result of human food refuse; therefore, the study of retrieved fish scales may provide reliable information on the season of capture and on paleoclimate and paleoenvironmental changes. Among Western European freshwater fishes, the grayling, Thymallus thymallus ¸ has the most easily recognizable scales and is a commonly recovered species from Palaeolithic contexts. This study, therefore, is based on the growth pattern analysis of modern and archaeological scales from grayling specimens. The modern specimens were collected monthly in France (n  = 22), Switzerland (n  = 16), Finland (n  = 20) and Sweden (n  = 10). Scale growth patterns were measured using numerical analysis to a high accuracy. The results showed that the archaeological population of grayling is closer to the present Finnish population. Furthermore, the comparison of seasonal growth patterns between current and archaeological European populations demonstrated that graylings were normally captured during the spring at Le Taillis des Coteaux Magdalenian site. This type of approach can be used to understand environmental conditions at a low spatial scale and also to help identify fishing seasons during archaeological periods.

The Canadian ‘staples thesis’ literature has documented both the risks (in the tradition of Harold Innis) and the opportunities (in the tradition of W. A. Macintosh) inherent in economies that are dependent on the export of minimally processed natural resources. The key risk is that of retarded long‐term growth as a result of a lack of diversification and over‐dependence on foreign capital and markets. This article argues that the demographic consequences of staples approaches to development also make it difficult to achieve diversification. It profiles Australia's Northern Territory as an example of a mining‐dependent (fiscal) economy that demonstrates a particular demographic profile consistent with what might be expected of a resource frontier. The article argues, however, that restrictive demographic characteristics persist (high sex ratios, high population mobility, disadvantaged position of indigenous people and remote dwellers) even though mining has become an insignificant direct employer (less than one percent of the workforce) and the services sector drives the labour market. This persistence can be linked to the Territory and federal government expectations of economic development patterns in the region and the frontier mythology created around the Northern Territory. Addressing the demographic imbalance is a critical step towards realizing ambitions for economic diversification.  相似文献

媒介-空间辩证法:创意城市理论新解   总被引:1,自引:0,他引:1  
李蕾蕾 《人文地理》2012,27(4):44-48,82
本文采用思辨方法,以作者对现代城市空间的观察,以及"媒介物"和"媒介表征"在城市空间的渗透,作为出发点,探讨媒介与城市空间的辩证关系,增进有关媒介和城市及其相互作用的认识。文章指出媒介-空间辩证法的知识基础,来自于新兴交叉学科"媒介与传播地理学";然后对媒体的空间性和空间化过程及其在城市空间的具体表现和可能影响,进行了初步分析,建立了媒体与城市空间的交互分类体系;通过借用"媒介的物化"和"物的媒介化"思想,将媒体与城市空间的辩证关系,与创意城市的理论探讨相关联,指出媒介-城市空间辩证法对于创意城市的理论建构,具有重要的启发意义。  相似文献
