The Spatial Structuring of Central Places

The spatial structuring of “classical” central place systems is the primary concern of this research. Emphasizing the development of such systems from basic spatial relations between centers and hinterland locations (rather than as a result of an underlying geometry of regions), this paper takes an optimization approach to the siting of central places in a single-good system. The objective function is shown to be one that maximizes both market coverage of demand and market overlap. Access to this objective is given through the natural slack covering model.     

ANALYSIS OF THEORETICAL,METHODOLOGICAL AND EMPIRICAL RESEARCH IN THE JOURNAL OF REGIONAL SCIENCE*

ABSTRACT. This paper examines the impacts of JRS articles in the areas of theory, methods and empirical analysis, as represented by subsequent citations reported in the Social Sciences Citation Index. A model relating the mix of theoretical, methodological and empirical research published in the JRS to subsequent citations is estimated. The time distribution of theoretical and empirical citations also indicates that the knowledge diffusion process in these two areas may be segmented.     

ECONOMETRIC MODELING OF INTERREGIONAL LABOR MARKET LINKAGES*

ABSTRACT. This paper presents a statistical procedure for empirically establishing linkages between regional economies. Using Granger's definition of causality and the final prediction error technique for lag-length specification suggested by Hsiao, a linked, multiregional employment model is developed. The forecast performance of the linked model is compared to models which do not include interregional linkages. It is shown that forecast error is reduced by taking into account employment interrelationships between regions.     

The stone circle sites of Komaland,northern Ghana,in West African archaeology

An Iron Age complex which flourished around the fifteenth to the seventeenth century AD is currently under investigation in Komaland, northern Ghana. The complex is known chiefly from its numerous burial sites characterized by stone circles and earth mound superstructures, and containing human and animal burials, domestic pottery, milling stones, metal implements and cast figures, together with ubiquitous and distinctive terracotta sculptures. This paper discusses the findings from the first season's excavation and their significance in West African archaeology.

Résumé Des recherches actuellement en cours portent sur un complexe de l'Age du Fer, qui a prospéré entre le 15e et le 17e siècle après J.C., en Komaland, au nord du Ghana. Le complexe est connu surtout par ses nombreux sépultures caractérisées par des cercles de pierres, avec comme superstructures des tumulus de terre où se trouvent des inhumations de humains et d'animaux, de la céramique domestique, des molettes, des outils en métal, et des figures coulées, avec des sculptures en terre cuite ubiquistes et distinctives. Cet article présente des résultats de la première saison de fouilles, et discute de leur signification dans l'archéologie de l'Afrique Occidentale.
