    الوصف: The authors consider the definition and measurement of deprivation and of rurality in the context of health-care research. Parallels are drawn between the methodological issues involved in the measurement of deprivation and of rurality. An empirical study of the South West of England reveals the extent of disagreement between standard rurality measures; in particular, the authors suggest that rural deprivation will be poorly represented by the conventional approaches. They argue for the development of new approaches to the measurement of deprivation in rural areas, in which advantage is taken of contemporary data sources.

    الوصف: The United Kingdom has experienced different local taxation regimes in each of the last three financial years: Namely the property-based household rates; the personal community charge or ‘poll tax’; and the hybridised personal community charge adjusted for neighbourhood ‘transitional relief’. The geographical impact of these changing policies in the Inner Areas of the City of Cardiff is examined, highlighting the importance of historical rateable values and household sizes. By using a purpose-built street-level database, the implications of the different taxation systems are examined at increasingly detailed geographic scales, and the complexity of their impact is illustrated. This analysis focuses upon the geographical effects of using administrative community boundaries for the allocation of transitional relief in Cardiff, Wales.

    الوصف: In this paper the refinement and application of a technique for the generation of surface models of population and related information are examined. With use of this technique the efficient generation of geographically extensive, high-resolution surfaces is described. The resulting database facilitates a range of improved spatial analyses. Some of these are more flexible means of accomplishing conventional tasks, such as the computation of incidence rates and the estimation of population for nonstandard areal units. Additionally, surface concepts are able to support innovative techniques, such as the identification and characterization of discrete settlements. Applications are described which demonstrate the range of possible analyses.

    الوصف: In three related papers the economic and spatial characteristics of a set of retail stores locating under welfare-maximizing and profit-maximizing criteria are explored. In this first paper, a set of location-spatial interaction models is formulated and the locations and sizes of stores which maximize the accessibility benefits to consumers are determined. An algorithm for computing such configurations is proposed and a set of numerical examples is used to explore the variation of these configurations under changes in the number of stores and the parameters which govern the spatial behaviour of consumers.
