A study of migration processes in the Moscow Capital Region over the period 1970-1985 begins by assessing their contribution to overall population growth within the region vis-à-vis natural increase and territorial and administrative changes. Attention then is turned toward movements both within the Moscow Capital Region and between it and other oblasts in the European RSFSR. Although the overall volume of migration within the Moscow Capital Region and between it and remaining oblasts of the European RSFSR declined, the relative popularity of the former as a destination among migrants in European Russia remained unchanged (translated by H. L. Haslett, Birmingham, UK).  相似文献

Quantitative fabric analysis was applied in order to discriminate better among white marbles from various quarries of archaeological interest. This method provides an effective complementary tool to a characterization based upon petrography, cathodoluminescence microscopy and stable isotopes. Very good discrimination of marbles is achieved with the help of simple variables such as major axis and the shape-specific PARlS-factor. Using quantitative fabric analysis, marbles with similar cathodomicrofacies, as, for example, the Naxian quarries of Apiranthos, Koronos, Flerio and Kinidaros and the quarry of St. Beat (French Pyrenees), can be distinguished from each other. Marbles collected within one quarry may display dissimilar cathodomicrofacies. The common origin of such specimens can be determined with the aid of quantitative fabric analysis, as shown for the quarries of Kinidaros as well as St. Béat.  相似文献

ABSTRACT An empirical regularity designated as the Number‐Average Size (NAS) Rule was first identified for the case of Japan by Mori, Nishikimi, and Smith , and subsequently extended to the United States by Hsu . This rule asserts a negative log‐linear relation between the number and average population size of cities where a given industry is present. In this paper, we utilize the cluster‐identification methodology developed by Mori and Smith to sharpen this notion of “industrial presence” by focusing only on cities that constitute at least part of a significant spatial agglomeration for the given industry. Our key result is to show that the NAS rule continues to hold (even more strongly) under this sharper definition.  相似文献

This paper makes a distinction between output maximizing and cost minimizing approaches to national economic policy. The paper argues that because the benefits of economic activity and its cost are frequently conferred upon distinct groups in society, it is not automatically true that output maximization is the best strategy, as is presently assumed. This result is especially true when the problems of distressed economic regions are the focus of our concern. The national and multi-national firms which make decisions pertaining to the economic life of local communities make those decisions not on the basis of the costs and benefits to the community, but with regard to their private balance sheet. As a result, it frequently happens that communities of individuals must bear social costs far in excess of the private gains to the firms in question. From a policy standpoint, this is not an efficient use of our social and economic resources. In the absence of any type of comprehensive economic planning a rational market-oriented economic strategy would be one which seeks to minimize social costs.  相似文献

With the view that travel behavior stems from the principle of utility maximization, in this paper I present a spatial translog demand model that accounts for interdependence among travel alternatives and that handles varying elasticities of substitution for various destination pairs. Using simulation as the mode of inquiry, this model describes the effect of spatial size, spatial configuration, and spatial substitution on spatial interaction. In addition to indicating how varying spatial sizes and configurations affect the average trip length and the trip making pattern, the simulation results also point out the possible effect of having spatially dependent locations in the system. Competing destinations increase the attractiveness of nearby locations, and complementary destinations reduce the impeding effect of space. The model is primarily relevant to the demand for shopping trips.  相似文献

A recently resolved debate centred on the interpretation of a major set of INAA data that was based on Olmec ceramics from Mexico. In an attempt to answer questions arising from the debate, this paper discusses the effect of numbers of samples chosen for data interpretation. It also presents interpretations of the ceramic data set based on a bivariate data‐splitting approach and compares the results of this with the multivariate analysis approaches employed by the initial publishers of the data.  相似文献
