Legacy databases and GIS: a discussion of the issues illustrated by a case study of archaeological site data from southeast Alberta,Canada

Many institutions and agencies are currently faced with the issue of geographic information systems‐enabling legacy databases. The problems can be acute for data sets that have been compiled through many years, using different standards and levels of recording. To explore these issues further, we report on a data quality assessment undertaken in 2002 for a subset of the archaeological site database of the province of Alberta, Canada. Our work shows that positional ambiguities in the data set can be highlighted and corrected by relatively straightforward procedures. This case study also provides an indication of the amount of work effort that will be involved in validating or ‘cleaning up’ data sets so model results and analyses undertaken with them are more reliable.     

La Psychologie des Peuples et Ses Applications Durant L’Entre-Deux-Guerres

Résumé  La psychologie des peuples a connu un grand succès dans les années 1930 dans les milieux les plus divers: sur les bancs de l’Université, tant des facultés de lettres que de celles de médecine, comme dans le monde colonial. Elle demeure imprégnée des postulats raciologiques du siècle précédent: hérédité raciale, influence du milieu géographique et du climat dans la formation des caractères nationaux, représentation inégalitaire de la différence et ses usages politiques ont été manifestes dans le domaine de la politique coloniale. Les enseignements de la psychologie ethnique ont, en effet, eu des applications directes dans la politique scolaire à travers la mise en place d’un enseignement rudimentaire et à tendance ségrégationniste qui a réduit considérablement les ambitions de la mission civilisatrice. Carole Reynaud Paligot, née en 1966, est actuellement boursière de la Fondation pour la mémoire de la Shoah. Ses recherches portent sur l’histoire des pensées raciales et l’histoire des intellectuels aux xix ^e et xx ^e siècles. Elle a notamment publié Parcours politiques des surréalistes 1919–1969 (Paris, CNRS éditions, 1995), La République raciale 1860–1930. Paradigme racial et idéologie républicaine, préfacé par Christophe Charle (Paris, Presses universitaires de France, 2006) et Races, racisme et antiracisme dans les années 1930 (Paris, Presses universitaires de France, 2007).     

Functional specialization across space: a case study of the Canadian Electricity Industry, 1971–2001

This article examines the location of functions within the electricity sector in Canada from 1971 to 2001, using a centre‐periphery model. Power generation, distribution and retailing are generally carried out by multiestablishment crown corporations. Location patterns of different functions—management, scientific, production, etc.—are analyzed via the use of occupational groups. The spatial distribution of functions is found to be generally consistent with centre‐periphery relationships, with evidence of a growing functional specialization between large metropolitan and nonmetropolitan locations. However, differences emerge depending on power generation sources: fossil fuels, hydro, nuclear, solar or biomass. The choice of a power generation source has consequences for local economies.     

Public participation geographic information systems (PPGIS): challenges of implementation in Churchill,Manitoba

Public participation geographic information systems (PPGIS) increasingly are utilized in geographic research, yet researchers rarely are provided with guidance on how to implement PPGIS in an appropriate and effective manner. This article reports on the process of research that explores responses to current and future local tourism development offered by a sample of residents using a modified PPGIS approach called ‘community action geographic information system’ (CAGIS). The conceptual development of CAGIS is reported and the challenges encountered during its implementation in Churchill, Manitoba during 2005–2007 are reviewed. It is suggested that researchers wishing to conduct similar research should undertake thorough preliminary fieldwork to assess the likelihood of finding agreement on a common problem; acquiring adequate resources; establishing collective responsibility for the project's outcome; attaining stakeholder support; developing trust and meaningful relationships; and incorporating indigenous knowledge appropriately. Feedback of results to community members also should be an integral part of the research process. A number of feedback mechanisms are reported, including an interactive weblog, which helped facilitate communication between heterogeneous groups in Churchill. Although ambitions for a truly participatory GIS approach to this project have been set aside, it is held that PPGIS can yield positive outcomes for communities and academia. Sharing this research experience will be useful to others who venture into PPGIS research, especially in northern communities.     

Residential segregation and inequality: Considering barriers to choice in Toronto

Segregation of visible minorities has persisted throughout time in Toronto. In examining these concentrations, the literature has been heavily focused on the notion that visible minorities are choosing to live in proximity to their respective ethno-racial groups and that these are spaces of aspiration rather than marginalization in Canada. This paper raises questions about the assertion of “self-segregation” by emphasizing affordability constraints on residential choices that are often rooted in discrimination in the labour market. Census data from 2016 and an adopted neighbourhood classification scheme were used to understand the spatial patterning of visible minorities in the Toronto census metropolitan area and highlight differences in the socio-economic characteristics of visible minority dominant and white dominant census tracts. The findings invite the inference that economic opportunities play a critical role in the residential choices of visible minorities and raise concerns about the quality of life in visible minority neighbourhoods. This research contributes to our understanding of how social inequalities have impacted the socio-spatial organization of the city of Toronto.     

Flood risk mapping in southwestern Nova Scotia: Perceptions and concerns

Flood risk mapping allows for informed decision making regarding personal and community planning. Resistance to flood risk mapping can be driven by potential decline of property values. This paper explores resistance to flood risk mapping through the lens of climax thinking. Climax thinking is a novel theory guiding explorations of resistance to proposed land use changes. The aim of this study was to understand flood experiences, the presence of resistance to flood risk mapping, and whether climax thinking could help explain this resistance. To address this, surveys were administered to residents in the Nova Scotian towns of Liverpool and Bridgewater. We found that one third of respondents have experienced flooding, yet the majority have not seen a flood risk map, nor were they concerned about the potential impacts of flooding. Only one sixth of respondents exhibited resistance to flood risk mapping because of potential loss to property value. Dimensions of climax thinking were predictive of this resistance, specifically ignorance of an individual's own ability to adapt and inability to recognize the impact of their adaptation decisions on others, which together quadrupled the predictive power of the ordinal regression model. These insights can be applied to support the acceptance of flood risk mapping.     

The spatial economy of North American trade fairs

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.
