"The paper studies the regional demographic trends in France from 1968 to 1990.... The study follows two main objectives: (1) Analysis of the main regional migration and population trends over the three census periods from 1968 to 1990. (2) Analysis of the growth trends of different types of regions on the basis of typifying the ?zones d'emploi' (labour market regions) according to economic criteria and settlement structure criteria. The large-scale patterns of the population and migration trends seem to be relatively stable in comparison to the massive change in the general economic and political framework in France and Western Europe.... The different region types, however, show more distinct changes." (SUMMARY IN ENG AND FRE AND RUS)  相似文献

The localization or representation of mental abilities in the brain have always been considered as key questions for understanding the organization of the human nervous system. Particularly with the advent of modern electrophysiological and imaging techniques that provide maps of electromagnetic fields and metabolic processes on the living central nervous system, the representation theory is experiencing a scientific renaissance in neurology, but is only one theory, however, in the succession of a long philosophical tradition dealing with the possible identification of mental phenomena and brain processes. This dichotomy was formulated at the latest in the Cartesian dualism of res cogitans and res extensa of the mind-body problem. Nowadays philosophical discussion, on the contrary, is dominated by monistic concepts that attempt to explain the mental realm on an organic foundation in order not to succumb to the problem of a psychophysical dualism. Of these, the identity theory offers a philosophically plausible concept postulating that the identity of brain conditions and mental phenomena is based on organic foundations. In this theory, the efforts of brain research converge on the representations of mental phenomena in the human nervous system. In a comprehensive approach, both concepts could complement each other.  相似文献

In recent decades, many Appalachian households have experienced declining incomes due to the loss of traditional male jobs in the mining and manufacturing sectors. One response to this decline has been an increase in female employment in formal sector activities. Another response is homework, or the home-based production of goods and services for sale in the formal and informal sectors. In rural Appalachia, where formal jobs are often unavailable or inadequate to support a household, many women are engaging in homework as an economic strategy. Consequently, economic restructuring cannot be fully understood without analyzing household strategies and gender relations. This paper examines the intersection of gender, households, and economic restructuring as it relates to women's homework and employment shifts in rural Appalachia. Research for this paper entailed qualitative interviews with 50 West Virginia women who are engaged in the home-based production of goods and services. The study analyzes the variety of homework activities done by rural women, their contribution to household incomes, and the effect of these activities on gender relations and divisions of labor in the home. The research forwarded in this study advances a conceptual understanding of household economic strategies and has some practical applications for women and economic development in underdeveloped regions .  相似文献

ABSTRACT This paper extends the research of Hyclak and Johnes (1989) in analyzing the relationship between the rigidity in real wages and state unemployment rates. It presents evidence contrary to the empirical findings of Hyclak and Johnes in that measures of real wage rigidity are not robust over time in explaining changes in state unemployment rates. Moreover, an alternative proxy accounting for divergent growth patterns across states does not significantly affect changes in state unemployment rates.  相似文献

ABSTRACT. Data for 28 metropolitan areas over a 15-year period are used to determine the impacts of government spending, taxes, and public infrastructure on total employment and disaggregated employment. After carefully controlling for the government budget constraint we find that taxes are negatively related to total employment and education spending is positively related to total employment. Nevertheless, we find that it is difficult for metropolitan areas to influence the composition of their employment with government tax and expenditure policies. Moreover, at current levels of public infrastructure, marginal changes in infrastructure have no strong effect on employment.  相似文献

ABSTRACT. The problem of locating a point that is as far as possible from arcs and nodes of a network is investigated. Each arc or node may have a different multiplicative factor (weight) for its distance. A graphical solution approach, as well as a computational algorithm, is presented.  相似文献

ABSTRACT. A large proportion of regional production takes place in nontraded goods and services. In addition, significant productivity increases can be observed in some segments of this sector. Starting from these two empirical observations we construct a model of growth in a two-region setting with factor mobility. The growth process is based on endogenous technological change in the nontraded input sector, whose output serves as an input in the production of one of the two final goods, the so-called industrial good. We consider two extreme cases, one with locally limited, the other with interregional knowledge spillovers. Conditions are established under which interior solutions with production of local inputs and steady-state growth in both regions result, and others under which we find a core-periphery pattern with growth concentrated in one region only. The stability of the equilibria is discussed by considering the transition processes. Finally, it is shown that catching-up as well as leapfrogging may occur, if new technologies become available.  相似文献

ABSTRACT. Johansen's (1988) multivariate test for cointegration is first applied to four models involving quarterly state data and five variables, along with a national model based on Friedman and Kuttner's (1992) model of money demand, which uses three variables. Each regional model consists of frequently used national and state series, for which theory suggests the possible cointegration of several series pairs. Beginning with all five series, however, one state model is found to be cointegrated over each of 20 successive estimation intervals. The money demand model and one state model are not cointegrated over the same intervals. In the cointegrated case, five-year experimental forecasts show that error correction mechanism (ECM) and Bayesian ECM models outperform all other approaches. More importantly, forecasting performance improves further by respecifying the ECM model based on three cointegrated series pairs rather than the five-component cointegrating vector. For the two noncointegrated systems, the first-difference model suggested by the cointegration/ error correction literature is far superior to VAR in levels over both shortand long-term horizons.  相似文献
