The first section of this two‐part paper describes my historical geographical career, particularly the topics and issues I have pursued and the changing intellectual environment in which they have been situated. The second section offers a summary interpretation of the emerging human geography of early‐modern Canada followed by some reflections on its contemporary implications. This interpretation stresses the extent to which boundaries and discontinuities marked early Canada, and contrasts a pinched Canadian experience with the land with a far more expansive American one. It shows how deeply difference was constructed and ingrained in the Canadian past, and suggests some challenges and opportunities that follow from this inheritance.  相似文献

The fur trade detached European commercial capital from Europe, relocating it in the North American interior. There it worked out a set of largely taken-for-granted assumptions and practices - what might be called the discourse of the fur trade - that embodied a commercial geography and closely related strategies of Native management. These strategies rested on a politics of terror, a theatre of power, and complex alignments of Native and white interests. Native and white agency were often reinforcing but, overall, the balance of power tilted towards whites, and the fur trade became a protocolonial presence in the Cordillera.
La traite des fourrures a eu pour effet de déplacer le capital commercial de ľEurope, en le relocalisant vers ľintérieur des terres de ľAmérique du Nord. Elle a pour une série de suppositions et de pratiques prises pour acquis, ce que ľon pourrait appeler son discours. Ce discours englobait une géographie commerciale et des stratégies qui étaient étroitement reliées et qui tou-chaient la prise en charge des autochtones. Les stratégies reposaient sur une politique de la terreur, une représentation du pouvoir et des alignements complexes des intérêts des autochtones et des Blancs. Souvent, les liens entre les deux groupes s'intensifiaient, mais dans ľensemble, la balance du pouvoir penchait du côté des Blancs. Le commerce des fourrures s'est alors trans-formé en une présence protocoloniale dans la cordillére.  相似文献

The uneven distribution of environmental hazards across space and in vulnerable populations reflects underlying societal inequities. Fragmented research has led to gaps in comprehensive understanding of and action on environmental health inequities in Canada and there is a need to gain a better picture of the research landscape in order to integrate future research. This paper provides an initial assessment of the state of the environmental health research field as specifically focused on vulnerable populations in Canada. We present a meta‐narrative literature review to identify under‐integrated areas of knowledge across disciplinary fields. Through systematic searching and categorization, we assess the abstracts of a total of 308 studies focused on the past 30 years of Canadian environmental health inequity research in order to describe temporal, geographical, contextual and epistemological patterns. The results reveal that there has been significant growth in Canadian research documenting the uneven distributions and impacts of environmental hazards across locations and populations since the 1990s, but its focus has been uneven. Notably, there is a lack of research aimed at integrating evidence‐based and policy‐relevant evaluation of environmental health inequities and how they are created and sustained. Areas for future research are recommended including more interdisciplinary, multimethod and preventive approaches to resolve the environmental burden placed on vulnerable populations and to promote environmental health equity.  相似文献

Canada is an evolving human geography that has nurtured difference and made a unitary state impossible. In this short essay I allude to the historical-geographical construction of Canada and the type of confederation it encouraged. I show how deeply different identities are ingrained in the fabric of this country. As the state cannot provide equally for all these identities, I consider the special claims of Native peoples and French speakers, particularly in relation to those of multiculturalism, and argue that the country has a particular responsibility to those societies that were here before the Canadian state, and found it superimposed upon them. Overall, I try to show that Canadian patriotism, based less on an overriding meta-narrative (which the country had never found) than on an appreciation of difference and the responsibilities of citizenship, provides a welcome alternative to either an exclusionary ethnic nationalism or a borderless electronic postmodernity.  相似文献

The recent introduction of standardised achievement tests in several provinces has created an opportunity for Canadian geographers to contribute to public and theoretical debates. Geographers are well‐equipped to comprehend and analyse the effects that neighbourhoods have upon pupil achievement. Independent of family background and school funding, such effects may be stronger in education than in other fields, such as voting behaviour and health research, but they have been ignored in recent public debates. They should be considered if informed judgements are to be made about whether specific teachers, schools, and boards are doing an adequate job. Analysis of the Ontario Grade 3 test results for 1997 in public schools in the City of Toronto and in Hamilton‐Wentworth indicate that social class had a greater effect on pupil achievement than language background. Differences in the determinants of achievement between these two urban centres may be attributable to local variations in occupational structure and residential patterns. L'introduction récente en éducation des tests de compêtences standardisés, dans plusieurs provinces, offre aux géographes canadiens l'occasion de contribuer aux débats publics et théoriques. Les géographes sont bien placés pour comprendre et analyser les effets de quartier sur le rendement scolaire des élèves. Indépendamment du milieu socioculturel et du financement scolaire, ces effets ont peut être plus d'impact en éducation que dans les domaines tels que le comportement électoral et la recherche dans le milieu de la santé, cependant, ils demeurent à l'écart des débats publics. Ces éléments doivent être considérés si l'on prétend juger en connaissance de cause l'efficacité et le rendement des écoles, le corps enseignant et les conseils scolaires. L'analyse des résultats d'examens de l'Ontario en 1997, pour les élèves des écoles publiques de la troisième année des villes de Toronto et Hamilton‐Wentworth, démontre que la réussite scolaire est plus liée au niveau socio‐économique qu'à l'origine linguistique. La divergence des facteurs de réussites des deux centres urbains est peut‐être attribuable aux variations des structures d'occupation locales et résidentielles.  相似文献

Understanding the dynamic behaviour of soil in the Anchorage basin in southcentral Alaska is essential for seismic hazard assessment of this highly seismically active region. The analysis of site responses for 40 sites from weak-motion and strong-motion data with amplitudes less than 0.1 g showed a strong influence of subsurface geological conditions on the characteristics of ground motion. Particularly, the sites in the central part of the city, including the downtown area, showed prominent resonance peaks around 1 Hz with amplification values up to about 4. The numerical analysis, based on one-dimensional multi-layer soil models shows that site response characteristics, and especially aforementioned peaks, are largely related to the thick, soft layer of Quaternary deposits, particularly cohesive fades of Bootlegger Cove Formation. The computed transfer functions for soil profiles of six representative sites are in accord with the site responses in the frequency range from 1 to 5 Hz. There is no significant change in amplification values below 2 Hz corresponding to large-amplitude (up to 0.38 g) ground motions; however, above 2-3 Hz the amplification values are greatly reduced in this case.  相似文献
