POISSON GRAVITY MODELS OF SPATIAL FLOWS*

ABSTRACT The purpose of this paper is to bring together a number of results on spatial flow models, and to reformulate them within a unified probability framework based on Poisson frequencies. To do so, a class of discrete stochastic processes, designated as independent flow processes, is developed which not only yields a complete characterization of Poisson flow frequencies, but also allows a wide range of gravity-type flow models to be formulated within this distributional framework. In particular, a hierarchical classification of 12 model types is developed, and each model type is shown to be characterizable directly in terms of behavioral axioms on independent flow processes.

ADDITIVE-RATIO MEASURES OF INTERACTMTY IN INPUT-OUTPUT SYSTEMS

ABSTRACT. A general axiomatic framework is developed for analyzing alternative measures of interactivity between the sectors of a given activity system (such as the industrial sectors of an economy). Within this overall framework, we analyze an ordinal class of additive-ratio measures which has been applied to a wide variety of systems, including both economic and ecological systems of activities. Our main result is to show that such measures can be characterized by four interactivity axioms. In addition, a wide variety of alternative measures are compared to additive-ratio measures in terms of this axiom system.     

Regional Weil-Being in Australia Revisited

There have been many studies of regional well-being in Australia, but few match the range of variables and spatial detail employed in this paper. Twenty two socio-economic variables were drawn from the 1986 census and used to classify all 148 Commonwealth electorates. Two procedures were adopted, both based on a principal components analysis, and compared to test the robustness of the classifications generated The first approach summed factor scores to provide a status index, and the second employed Ward's clustering algorithm. The resultant groupings are seen to both complement and reinforce each other and indicate the complex and often subtle variations in well-being across the country.     

The open method of coordination and policy mainstreaming: the European employment strategy and regional conversion programmes in the UK

This article is a critical exploration of the issues raised by the attempt to integrate aims and concerns derived from one European Union (EU) policy domain into another. It does this via an examination of the ways in which the European Employment Strategy (EES) has been taken into account in the design and initial implementation of Structural Fund programmes in the 2000–2006 round. In particular, it examines the nature of this ‘mainstreaming’ relationship in terms of the structures and mechanisms associated with current Objective 1 programmes operating in the UK. It maps out the vertical and horizontal linkages between European, national and regional levels, and assesses the extent to which strategic frameworks, programme guidance and programme content have successfully integrated EES considerations. The article concludes by identifying some implications for theories of European governance.     

Mapping Common Futures: Customary Communities,NGOs and the State in Indonesia's Reform Era

The post‐Suharto ‘Reform Era’ has witnessed explosive revitalization movements among Indonesia's indigenous minorities or ‘customary’(adat) communities attempting to redress the disempowerment they suffered under the former regime. This study considers the current resurgence of customary claims to land and resources in Bali, where the state‐sponsored investment boom of the 1990s had severe social and environmental impacts. It focuses on recent experiments with participatory community mapping, aimed at reframing the relationship between state and local institutions in planning and decision‐making processes. Closely tied to the mapping and planning strategy have been efforts to strengthen local institutions and to confront the problems of land alienation and community control of resources. The diversity of responses to this new intervention reflects both the vitality and limitations of local adat communities, as well as the contributions and constraints of non‐governmental organizations that increasingly mediate their relationships to state and global arenas. This ethnographic study explores participants’ experiences of the community mapping programme and suggests its potential for developing ‘critical localism’ through long‐term, process‐oriented engagements between communities, governments, NGOs, and academic researchers.
