GIScience and GISystems have been successful in tackling many geographical problems over the last 30 years. But technologies and associated theory can become limiting if they end up defining how we see the world and what we believe are worthy and tractable research problems. This paper explores some of the limitations currently impacting GISystems and GIScience from the perspective of technology and community, contrasting GIScience with other informatics communities and their practices. It explores several themes: (i) GIScience and the informatics revolution; (ii) the lack of a community‐owned innovation platform for GIScience research; (iii) the computational limitations imposed by desktop computing and the inability to scale up analysis; (iv) the continued failure to support the temporal dimension, and especially dynamic processes and models with feedbacks; (v) the challenge of embracing a wider and more heterogeneous view of geographical representation and analysis; and (vi) the urgent need to foster an active software development community to redress some of these shortcomings. A brief discussion then summarizes the issues and suggests that GIScience needs to work harder as a community to become more relevant to the broader geographic field and meet a bigger set of representation, analysis, and modelling needs.  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

This paper explores seven scenarios of Palestinian state formation and attempts to propose a suitable peaceful territorial solution to the Israel-Palestine conflict. The ‘good’ and the ‘bad’ features of each scenario are examined against the backdrop of recent geopolitical developments and the complex geographic and demographic realities of the region. Some of these scenarios suggest that a peaceful territorial arrangement should involve incorporating some Israeli territory, encompassing a broad segment of the Palestinian population and exploring the possibilities of sharing territory through condominium arrangements. Drawing anew upon the boundaries and partitioning principle of the 1947 United Nations Partition Plan for Palestine, the author offers a proposal for the peaceful and permanent settlement of the conflict. According to this scenario, Palestine would be repartitioned and divided into four political entities: A Palestinian sovereign area on 30.3 percent of the territory, a Palestinian autonomous region on 4.5 percent, an Israeli sovereign area on 55.6 percent, and areas under a condominium arrangement on 9.6 percent of the land. Arguably, such territorial configuration of space proposes genuine options for dealing with the geographical problems of refugee settlement, demography, ethnic composition, and the retention of Israel's national identity (i.e., Jewishness), whilst also suggesting a concrete basis for peaceful coexistence rooted in the geographical imperatives and realities of the region. Cet article évalue sept configurations possibles de l'État palestinien et tente de proposer une solution pacifique au conflit entre Israel et la Palestine. A la lumiere des développements géopolitiques récents ainsi que des réalités ggographiques et démographiques de la rggion, l'auteur examine le pour et le contre de chacune des sept configurations. Certaines configurations font éat du fait que, pour en arriver a une rgsolution pacifique, (a) Ifftat palestinien devra comprendre des territoires actuellement sous le contrdle d'lsrael; (b) il devra regrou- per une forte majorite de la population palestinienne; et (c) le partage des territoires par l'entremise d'enten- tes genre ‘condominium’ mérite d'sêtre exploré. S'inspirant à nouveau du principe des ‘frontieres et du morcellement des terres’ dont fait l'objet le United Nations Partition Plan for Palestine de 1947, l'auteur propose une solution pacifique et perrnanente au conflit. Selon le scenario prefgrt?, la Palestine serait redivisge sur le plan territorial. Quatre entité politiques résulteraient de ce re-morcellement: un état Palestinien souverain sur 30,3 pour cent du territoire, une rggion d'autonomie palestinienne sur 4,5 pour cent du territoire, un état Israélite souverain sur 55,6 pour cent du territoire et une région (9,6 pour cent du territoire) gérge par l'entremise dententes genre ‘condominium’. En même temps qu'elle propose des methodes concrétes de composer avec les problemes ggographiques en ce qui concerne l'établissement des réfugiés, la demographie, la composition ethnique des états individuels et le maintien de l'identite nationale d'lsrael, cette solution propose aussi une base solide pour la coexistence des deux nationalitgs, base ancrtée dans les imperatifs et les réalités ggographiques de la region.  相似文献

This paper contends that unfree Indigenous student labour at residential schools was a key—and underappreciated—component of settler colonialism in Canada. Colonial administration and the churches attempted to “civilize” and assimilate Indigenous people—and prepare the frontier for white settlers—through residential schooling. Labour, in accordance with Euro-Canadian gender norms, was expected to usher Brandon Industrial Institute (later Brandon Residential School) students from the “backwardness” of traditional lifeways to the industriousness and assimilation necessary for their roles in the serving classes of modern society. I use archival sources—newspapers, unpublished reports, Department of Indian Affairs documents, and United Church correspondence and photographs—and employ a version of Norman et al.'s “settler-colonial grid of recognizability” to examine student labour. This paper argues that the Department of Indian Affairs and church officials at Brandon Residential School sought to make Indigenous youth “legible” under the settler-colonial grid of recognizability through agricultural and manual work for boys and domestic labour for girls, both of which ensured the school's financial viability. I propose that this under-explored aspect of settler colonialism could be understood through three main themes—imperial settler-humanitarianism, the logic of containment, and productive bodies—that are traced across the lifetime of the school.  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

Interregional trade between Canada and the United States has undergone significant change since the inception of free trade. However, the magnitude of that change for the different regions in Canada and the United States has not been properly identified because of a lack of an appropriate measure. This paper introduces the concept of a quasi‐point and employs a spatial point pattern test to measure the degree of change in the interregional trade of Canadian provinces and US states, with an emphasis of that change on Ontario. It is found that the degree of change in the interregional trade flows is related to the degree of change in the provincial tariff rates.  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

This paper reviews selected evidence of environmental changes in the central Canadian Rockies during the 20th century. The instrumental climate record shows that mean annual temperatures have risen ca. 1.4°C over the last 100 years but seasonal patterns of change are complex. The greatest increases have been in winter temperatures (3.2°C / century). Precipitation data, though limited, show variable patterns of change on decadal scales with generally higher levels of precipitation in the mid-20th century. The longest streamflow record also shows considerable variability, with highest flows in the 1950s. A tree-ring-based temperature reconstruction indicates summer and spring temperatures in the last half of the 20th century are higher than any equivalent period over the last 900 years. Although no accurate regional estimates exist, glaciers have probably lost ca. 25% of their area in the last 100 years and may be smaller now than they have been at any time in the last 3000 years. These two lines of evidence suggest that the climate of the late 20th century is exceptional in the context of the last 1000 to 3000 years. Small but significant vegetation changes are taking place at the upper treeline ecotone in response to climate changes over the 20th century (e.g., seedling establishment). However, the most significant landscape change in the last 100 years is the transformation of the character of the montane forest due to a reduction in forest fire frequency, largely due to an active policy of fire suppression. Dans cet article, on révise certaines manifestations des changements environnementaux qui se sont produits dans les Rocheuses canadiennes au cours du 20ème siècle. Ce registre instrumental climatologique indique que les moyennes annuelles de température ont augmenté d'environ 1,4°C en 100 ans, mais les modèles de changements saisonniers sont complexes. Les plus fortes augmentations ont été notées dans les températures hivernales (3,2°C/siècle). Les données concernant les précipitations - bien que limitées - indiquent des tendances variables de changement selon les décennies et en général des niveaux plus élevés de précipitation au milieu du 20éme siècle. Le plus long enregistrement des débits d'un cours d'eau indique aussi d'importantes variations, les débits les plus forts se situant dans les années 1950. La reconstruction des relevés des températures faite à partir des cernes montre que les températures estivales et printanières de la deuxième moitié du 20ème siècle sont plus élevées qu'elles ne l'étaient durant les périodes correspondantes des 900 dernières annés. Même s'il n'existe aucune donnée règionale exacte, les glaciers ont probablement perdu à peu près 25% de leur superficie au cours du dernier siècle et ils ont atteint leur plus petite taille des 3000 dernières années. Ces deux preuves suggèrent que le climat de la fin du 20ème siècle est exceptionnel dans le contexte des 1000 à 3000 dernières années. Des changements mineurs mais significatifs s'effectuent actuellement dans l'écotone supérieur de la limite des arbres à cause des changements climatiques du 20ème siècle (ex. l'implantation de nouvelles pousses). Pourtant, pendant le dernier siècle, la transformation la plus significative s'est effectuée dans les forêts de montagne. Grâce à une politique active de suppression des incendies de forêt, ceux-ci sont beaucoup moins fréquents.  相似文献
