A Network Approach to Commuting 总被引:1,自引:0,他引:1
In this paper we present a model for commuting in a network of towns. A basic assumption is that all individuals have a given residential location and that every node in the network has a fixed number of jobs. We then propose a general model for the commuting of labor between the nodes in the network. 相似文献

The Dutch translation of Jacobus de Cessolis' Ludus scaccorum is an adaptation of the Latin text with so many interventions from the Dutch translator that the Dutch version becomes an independent plea for just behaviour. The context is presumably that of the Dutch comtal court of 1400. 相似文献

Data from the 1990 and 1993 Australian Electoral Studies are used to investigate whether public concern about the environment has declined in Australia over recent years. Questions of the ranking and structure of environmental concerns and of levels of support for environmental organisations are addressed. The data show that public concern about the environment remains high on an ‘agenda of long‐term issues’, that environmental concerns form two distinct clusters (termed ‘brown’ and ‘green') and that active support for environmental organisations correlates only with the green cluster. It is argued that these findings give no more than partial support to the ‘organisational’, ‘postmaterialist’ and ‘risk society’ perspectives on environmental issues. 相似文献

It appears that many people in Irian Jaya today are protesting against the manner in which they are, as they perceive it, being denied fundamental human rights, guarantees of social interaction based on fairness, and a reasonable share of economic benefits secured through ‘development’, and are searching for something that goes beyond this: a world in which they will enjoy health and a life of youthfulness; in which they will live with one another in peace and happiness, and have access to wealth without limit. In the past decade the number of ‘cargo’ movements has increased considerably and growing clouds of cargoism are spreading over the territory. In this essay we present data on activities from four areas in Irian Jaya. In the brief discussion that follows and in which we focus primarily on causal factors, we venture the thesis that in all these cases we have to do with (new) religious movements. The recurring combination of expectations based on traditional religious beliefs with feelings of political and economic discrimination may result in explosive situations. There will be little reason to assume that cargoism will decrease significantly. 相似文献

This paper examines the extent to which sectoral diversification can act as an insurance mechanism against fluctuations in regional gross value‐added growth rates. Portfolio theory is applied to the growth‐instability properties of German districts. Furthermore, a comprehensive diversification measure is defined. Stochastic Frontier Analysis is deployed in order to estimate whether diversification allows regions to achieve more efficient growth‐instability combinations. The results confirm that diversification does generate such effects. Spatial interactions do also play a role: The effects are less pronounced for regions whose economic performance is mainly driven by the surrounding regions. 相似文献
