AGGREGATION ERROR EFFECTS ON THE DISCRETE-SPACE p-MEDIAN MODEL: THE CASE OF EDMONTON, CANADA

The spatial analysis literature recognizes three sources of aggregation error, termed Source A, Source B, and Source C, which affect models relying on distance measurements between populations and facilities. We consider these effects with respect to aggregating from census enumeration areas to census tracts, on a popular location model. We identify a further source of aggregation error, which we dub Source D error, arising from the representation of facility sites by discrete points. Source D effects are of the same magnitude as Source A and B combined, much greater than Source C effects. Source D error is further significant, because, unlike Source A and B error, it can be eliminated only by disaggregating .
La littérature sur Vanalyse spatiale reconnaît trois sources d'erreur d'agrégation appelées erreurs de source A, B, et C. Ces erreurs influencent les modèles qui reposent sur des mesures de distance entre des populations et des installations. On considère les effets d'agrégation des secteurs de dénombrement en secteurs de recensement sur un modèle de localisation courant. On identifie une quatrième source d'erreur d'agrégation appelée erreur de source D. Cette erreur découle de la représentation des sites des installations par des points discrets. Ses effets sont du même ordre de grandeur que ceux des sources A et B combinées et beaucoup plus grands que les effets de source G. L'erreur de source D est d'autant plus significative à cause du fait que, contrairement aux erreurs de source A et B, elle ne peut être éliminée que par la désagrégation .     

In Search of Competitive Efficiency: Labour Process Flexibility in Canadian Newsprint Mills

This paper focuses on the strategies for production and work reorganization pursued in the Canadian newsprint industry during the 1990s. Many newsprint mill managers view new pulping technologies and increased labour process flexibility as the important keys to success in their never-ending quest to remain competitive in the U.S. market. These strategies are discussed in the context of two underlying themes: the nature of the particular competitive pressures faced by Canadian newsprint producers in the early 1990s and the specific nature of the labour process in newsprint mills. Evidence points to the central importance of achieving functional labour flexibility in newsprint mills and to the fact that numerical labour flexibility is not a viable strategy, given the continuous-process nature of the industry.

From Proletarian to Entrepreneur to Big Man: the Story of Noya1

The resemblances between Melanesian Big Men and capitalist entrepreneurs have long fascinated anthropologists. However, even though traditional leaders in Melanesian societies resemble entrepreneurs in certain respects they are motivated by different concerns. In this paper, I consider the career of Noya of the Eastern Highlands of Papua New Guinea to demonstrate the contrasts and confluences between the roles of big man and that of entrepreneur. Noya is neither a traditional big-man nor a pure capitalist, but has drawn selectively upon the logic of each in his drive to achieve promience. His life story provides insights into how big-men articulate with the capitalist world system.     

With This Body I Thee Worship: Sacred Prostitution in Antiquity

Why do ancient writers tell us that sacred prostitutes massed on the citadel of ancient Corinth? What are we to make of Herodotus’ famous account of the ancient customs of Babylon? Beard and Henderson examine the formation of the discourse of sacred, or cultic, prostitution both in classical texts and modern scholarship. They take a sceptical position on the existence, in Greece and the Near East, of institutions traditionally envisaged as ‘sacred prostitution’ and explore the uses which have been, and are still, found for such myth-making with the bodies of women, whether in the form of a ‘marriage-market’ or of various kinds of ‘sacred prostitution’.     

Global firms in local information societies: Work and employment issues for Europe

The strategies of large firms have a major influence on the evolution of the global information society because they dominate the markets for information and communication technologies. This paper examines the user rather than the producer role of large firms, and focuses on the surrounding issues relating to evolving patterns of work and employment. Its discussion of these issues and their policy significance reflects the perspective of the EU on what is effectively a global agenda on the future of work in the information society.     

SUPPLY ARMS AND OPTIMAL SPATIAL STRUCTURE*

ABSTRACT. A multi-plant producer has sole access to a region, and each of the plants processes a raw material which is drawn from its own exclusive supply area. Under these conditions what spatial structure of production (in terms of plant scale, plant frequency, supply-area size and supply-area shape) will enable region-wide or multi-plant profit to be maximized? The form of this optimal structure is shown to vary with prevailing level of price, which is exogenously determined.
