This paper investigates the establishment of trading regions in the global economy at the national level using a measure of trade intensity and a regional assignment algorithm that generates economically meaningful trading regions. Although there is definite regionalization in the global economy with regard to international trade, there is no evidence of an increase in the concentration of that regionalization over time. The geography of international trade is incredibly dynamic, with change related to political, historical and economic forces. Overall, trading regions have relatively few members and are increasingly a set of geographically close countries.  相似文献

Through a study of trade fairs, this article illustrates that relational approaches to economic geography are not limited to the sphere of economic and social relationships. These relationships are influenced by and, in turn, shape material realities, such as specific infrastructure and the labour market, in a reflexive manner. Trade fairs are “relational events” that bring together regional, national, and often international producers, users, suppliers, and other agents of a value chain or technology field for the purpose of exchanging knowledge about technological and market developments, building partnerships, and maintaining existing networks through learning by interaction and observation. However, these events are also situated in space and time, grounded in the contexts of particular industries, trade patterns, public and private investments, as well as the economic geographies of places. Focusing on North America, this article presents and analyzes data on the economic geography of trade fairs and their regional economic impact (number of events, exhibitors, attendees, exhibition space). It explores regional trade fair patterns and dynamic changes in major trade fair cities by emphasizing the role of history and industry context.  相似文献

Changes in the prices of homes and the reasons for those changes may be more accurately predicted from repeat sales of the same homes after controlling for their changed attributes and differences in time between their sales and resales. This paper analyzes 346 of 583 sold houses in the Glengarry neighbourhood in Windsor, Ontario, that were sold more than once between 1981 and mid‐2017, and a corresponding 414 of 737 sold houses in the city's Wellington‐Crawford neighbourhood, sold more than once between 1986 and mid‐2017. After comparing types of resold homes with once‐sold ones, a repeat sales model predicts a first period of increasing annual percentage changes in resale prices compared to sale prices during the 1980s, followed by a second period of stagnation and possible decreases until 2011, and then increases during a third period after that. In addition, changes in resold homes’ attributes of the dwelling unit and neighbourhood are a second type of neighbourhood change in two inner‐city neighbourhoods during the past 30 or more years.  相似文献

In this paper, we map the international trade in electronic waste (e‐waste). We quantify the directions and magnitude of this trade at the global scale and examine the utility of the pollution haven hypothesis for explaining the observed trade patterns. Our results demonstrate four key findings: the international trade in e‐waste is a more complex story than being one about ‘rich’ countries dumping waste in ‘poor’ countries; the trade in e‐waste is highly regionalized, with intra‐regional trade accounting for most of the total trade flows; the pollution haven hypothesis is an important, but partial, explanation of observed trade patterns; and there is a need to conceptualize the trade and traffic of e‐waste as open ended and contingent processes facilitated by situated practices of wasting and valuing that rely on geographic difference and mobility for the exchanges between the domains of waste and value to occur.  相似文献

This article argues that China's agreement in 2012 to loan Canada two panda bears is emblematic of animals’ simultaneous material‐symbolic inclusion and exclusion in contemporary politics. Employing a material focus, this article draws a connection between the panda gift and the promise to which it is attached: a promise of material flows; of Chinese access to Canadian resources, especially; and controversially, tar sands oil. Common to geographical flows of both pandas and oil is a devaluation of nonhuman life. In one flow, two pandas cross the Pacific for a decade of captivity at the Toronto and Calgary Zoos, where visitors will pay to view the permanently visible pandas. In the other instance, oil will be shipped across the same ocean, oil whose production comes at great cost to wildlife, including caribou, birds, and fish, and whose spill at any point along its journey to China would devastate marine and terrestrial wildlife populations. Stark power imbalances between species are at the heart of both of these flows and their material consequences. This article argues that, in emphasizing what the pandas symbolize, the extent to which their own and others’ lives are materially affected is elided.  相似文献

Snow cover is often measured as snow‐water equivalent (SWE), which refers to the amount of water stored in a snow pack that would be available upon melting. Snow cover and SWE represent a source of local snow‐melt release, and are sensitive to regional and global atmospheric circulation, and changes in climate. Monitoring SWE using satellite‐based passive microwave radiometry has provided nearly three decades of continuous data for North America. The availability of spatially and temporally extensive SWE data enables a better understanding of the nature of space‐time trends in snow cover, changes in these trends and linking these trends to underlying landscape and terrain characteristics. To address these interests, we quantify the spatial pattern of SWE by applying a local measure of spatial autocorrelation to 25 years of mean February SWE derived from passive microwave retrievals. Using a method for characterizing the temporal trends in the spatial pattern of SWE, temporal trends and variability in spatial autocorrelation are quantified. Results indicate that within the Canadian Prairies, extreme values of SWE are becoming more spatially coherent, with potential impacts on water availability, and hazards such as flooding. These results also highlight the need for Canadian ecological management units that consider winter conditions.  相似文献

The Innis model of staple production has been used as the framework for evaluating many Canadian resource trades. This paper argues that Japanese resource trade differs from that with Europe or the United States and that the distinct set of institutional arrangements governing Japanese resource trade requires the modification of the Innis model to recognize this new form of Canadian staple production and trade. The one billion dollars per annum Canada-Japan coal trade provides a detailed case study of the institutional complexity of Japanese resource trade, as revealed through corporate strategies, trade intermediaries, equity investment, loan arrangements, export contracts, and public infrastructure. Minority Japanese investments in joint ventures replace the dominant role of foreign capital in earlier versions of the staples model. The role of finance capital is highlighted by Japanese loans typically exceeding equity investments in size. The high transaction cost of negotiating hundreds of contracts is reduced through the use of sogo shosha (Japanese general trading companies) as intermediaries. Unequal relations are demonstrated by the greater risk borne by local investors as private firms provide equity and public institutions invest in infrastructure. The Quintette mine in northeast British Columbia highlights these risks. Overall, the complexity of the Japanese supply system reduces the bargaining power of any single supplier. However, the stability promoted by the security objectives of the Japanese supply system leads to long-term trading relations that can provide corporate cash flows and maintain community viability during cyclical downturns in the industry. Le modele d'lnnis sur la production des matieres premiéres a servi a analyser les effets du commerce des ressources naturelles au Canada. Le texte maintient que les echanges de ressources naturelles avec lelapon different de ceux qui lient le Canada aux Etats-Unis et à l'Europe, et que la particularité des structures servant à administrer le commerce avec le Japon nécessite une modification du modele d'lnnis vouéà l'analyse des effets de ce commerce. Le texte se penche sur le commerce du charbon entre le Canada et le Japon, dont la valeuratteint 7 milliard$ parannée. Cette étude de cas va permettre de saisir la complexité institutionnelle des échanges ayant trait aux ressources naturelles avec le Japon, perceptible dans les stratégies des corporations, la présence d'intermédiaires, les investissements, les modalités de prêts, les contrats d'exportation et les infrastructures. Les investissements minoritaires des japonais dans des entreprises conjointes remplacent le rôle dominant des investisseurs étrangers caractéristique des modeles antérieurs d'extraction des matieres premieres. Le rôle accru du capital financier est souligné par les prêts des japonais qui exddent habituellement leur achat d'actions. Les hauts cocits transactionnels lie's à la négociation de centaines de contrats est réduit par l'intermédiaire de sogo shosha (compagnies japonaises se spkcialisant dans les échanges entre corporations). Nous constatons l'exis- tence de rapports inégaux olj le gros des risques est assumé par les investisseurs locaux et les agences gou- vernementales qui assurent la mise en place d'infrastructures. La mine Quintette dans le nord-est de la Colombie-Britannique illustre bien ces risques. La complexité du systeme d'approvisionnement japonais réduit les atouts dans les négociations des fournisseurs pris individuellement. It demeure que la stabilité, qui découle des objectifs d'approvisionnement a long terme des japonais, permet d'établir des rapports d'échange durables qui garantissent aux entreprises des revenus persistants ainsi que la prospérité des localites olj se trouvent les opérations d'extraction. Ces localités se trouvent alors soustraites aux effets des cycles économiques.  相似文献

Scientists advise limiting global warming to 1.5°C with substantial actions by 2030. Our viewpoint argues that climate response strategies in Canada have underemphasized and underestimated the potential contribution deep energy retrofits can make to greenhouse gas (GHG) emissions reductions, leading to inadequate responses in the building sector, and that Canada can (and should) be ambitious with building retrofits over the next decade. GHG savings from building retrofits can be realized more quickly than GHG reductions from other sectors, and either deliver net cost savings or are cost‐effective when compared to other mitigation measures. Retrofits can also provide social and economic benefits, such as improved health and comfort, and lower energy costs. This paper reviews energy use and building retrofits in Canada and argues the following should be implemented: (1) focus innovation on deep energy retrofit processes, not singular retrofit actions; (2) maximize both social and environmental benefits; (3) improve data gathering and availability for analysis and delivery; (4) innovate for a process of decisions and to avoid “dropouts” during the retrofit process; and (5) focus innovation on business models that maximize benefits.  相似文献

Community‐based conservation is experiencing a crisis of identity and purpose as a result of a disappointing track record and unresolved deficiencies. The latter include over‐simplified assumptions and misconceptions of “community,” the imposition of externally designed and driven projects at the community level, a focus on conservation outcomes at the expense of community empowerment and social justice, and limited attention to participatory processes. New approaches are urgently needed to address these weaknesses and to counter a rising trend towards environmental protectionism and a preference for conservation approaches at an eco‐regional scale that threaten the interests of local and Indigenous communities. We propose that three core principles of community‐based participatory research (CBPR)—(1) community‐defined research agenda; (2) collaborative research process; and (3) meaningful research outcomes—hold much promise. Drawing on the experience of a research partnership involving the James Bay Cree community of Wemindji, northern Quebec, and academic researchers from four Canadian universities, we document the process of applying these principles to a community‐based conservation project that uses protected areas as a political strategy to redefine relations with governments in terms of a shared responsibility to care for land and sea. We suggest that basic assumptions of CBPR, including collaborative, equitable partnerships in all phases of the research, promotion of co‐learning and capacity building among all partners, emphasis on local relevance, and commitment to long‐term engagement, can provide the basis for a revamped phase of community‐based conservation that supports environmental protection while strengthening local institutions, building capacity, and contributing to cultural survival.  相似文献

The inter‐archipelago exchange of adzes after colonisation was not considered in the widely referred to culture historical Polynesian adze typology developed by New Zealand archaeologist, Roger Duff. This portable x‐ray fluorescence (pXRF) geochemical study re‐examined the assemblage of the adzes in museum collections that were classified into Duff Types by archaeologists Gonzalo Figueroa and Eduardo Sanchez. This paper investigates the geochemical patterning of the Polynesian basalt adze types found on the Pitcairn and Gambier Islands by (1) identifying volcanic rock type of the artefact (2) matching the geological sources used to make the artefacts using a Discriminant Function Analysis (DFA) and, (3) comparing an artefact's identified source to its recorded find spot. The results of the analyses conducted in this paper identified that 16 (8%) adzes had originated from different island groups than where they were collected from in the twentieth century. These adze exchanges provide more evidence of long‐distance Polynesian connections that occurred after people initially colonised central east Polynesia and thus further refutes the idea that these islands were occupied in isolation – a critical re‐evaluation of Duff's typology is therefore required.  相似文献

This invited essay responds to requests by the Suzanne Mackenzie Memorial Lecture Nominating Committee and by the former Editor of this journal to take stock of and provide intellectual‐historical context for the major preoccupations that characterized feminist urban geography in its early years, by means of a personalized reflection in light of the author's own positioning in those debates and interventions. The thread running through the article is that of the relationship between the ‘economic’ and the ‘social’ in urban geography. The last section briefly considers new challenges that neoliberalism poses for critical feminist urban geographies.  相似文献

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

Geomorphology in Canada, as elsewhere, has evolved into an essentially bipartite discipline focusing either on ‘process’ or broader ‘historical’ (Quaternary) landscape interpretation. A growing emphasis on process‐oriented research that relies increasingly on instrumentation and computational technologies has occurred. Critics of such research note limited applicability for landscape evolution, fashionability of methods and limited societal relevance. Indeed, some say we are not seeing the landscape for the processes. This article discusses the changing nature of geomorphology since the Quantitative Revolution of the 1950s including new advances, recent trends and challenges. Publication trends and recent advances suggest that the discipline is very healthy (following a slump in the early 1990s) and continues to evolve, which may reflect increasing research infrastructure and/or funding opportunities and new publications spotlighting Canadian research. Unfortunately, fundamental (less applied) research is threatened by funding program shifts, changing institutional pressures and a decline in research capacity from retirement attrition, and student recruitment challenges. Three research priorities are recommended: (1) continued fundamental research, (2) more integrated modelling to link micro scale processes to macro scale landform behaviour and (3) improvements in profiling our discipline amongst students and related professionals.  相似文献

Spurred by the literature on climate change and its calls for undertaking holistic research that more fully integrates the work of biophysical and social scientists, this article responds to the question: To what extent has climate change research in Canada embraced and been guided by the theories and tenets associated with interdisciplinarity and to what extent have integrated approaches been sensitive to cross‐cultural perspectives? It provides an overview of some of the epistemological issues raised in the interdisciplinarity literature that particularly impact research development and design. Furthermore, since much of the climate change literature that claims to be integrated or interdisciplinary draws from Indigenous Knowledge (IK), additional insights are provided from this perspective. The article develops a framework that can be used to undertake and/or evaluate research in a way that acknowledges “upstream” epistemological issues. The framework is then used to evaluate a comprehensive database (n = 282) of Canadian climate change articles. It is argued that an interdisciplinary approach adds a critical voice to the literature on integrated climate change research and is valuable because of its focus on epistemology and methodology. The article advocates the creation of a space for inter‐epistemological acknowledgement in which the academy develops an ethos of self‐reflection, while simultaneously respecting and integrating parallel knowledge frameworks, such as IK.  相似文献
