"Regional scientists remain interested in studying interregional differences in the growth rates of population and employment. Following the earlier work of Carlino and Mills, this paper examines growth trends at the county level in the U.S. during the period 1981-1989. Five major sectors of employment are examined. A partial adjustment model is developed that captures intercounty differences in amenities, business and fiscal conditions, demography, employment structure, and relative location. Some evidence is given that population and employment growth was simultaneous, although feedback effects apparently were not strong."  相似文献

第二次世界大战结束后,美国积极开展国际教育交流,大力招收外国留学生,人数随之与日俱增,并在20世纪70年代末达到高潮.与此同时,随着美国科技革命的展开和经济结构的转型,高科技人才严重短缺,于是,美国政府实施了允许外国留学生和访问学者永久性移民的政策.由于美国在工作环境、科研设备和工资水平等方面具有别国无可比拟的优越条件,许多来自发展中国家的留学生最终成为永久性移民.他们定居美国后,其母国遭受了预想不到的人才流失,他们在母国成长期间的抚养费、教育和医疗费,以及在美国读书期间各种费用等人力资本投资也随之流失.  相似文献

This paper examines the hierarchy of intra- and inter-regionaltrade flows within the Japanese economy over the period 1980–85–90.The methodology provides an opportunity to explore links betweenfeedback loops analysis and the extraction of a hierarchy offlows using ideas from superposition principles. The resultinganalysis of trade feedbacks may be seen to reflect the economicphenomena of horizontal and vertical trade specifications. Whilethe process is explored analytically, the results are presentedusing visualization to help identity the different permutationmatrices presenting the hierarchy of trade feedback loops.  相似文献

An analysis of population and social change in London wards in the 1980s   总被引:1,自引:0,他引:1  
"This paper discusses the estimation and projection of small area populations in London, [England] and considers trends in intercensal social and demographic indices which can be calculated using these estimates. Information available annually on vital statistics and electorates is combined with detailed data from the Census Small Area Statistics to derive demographic component based population estimates for London's electoral wards over five year periods. The availability of age disaggregated population estimates permits derivation of small area social indicators for intercensal years, for example, of unemployment and mortality. Trends in spatial inequality of such indicators during the 1980s are analysed and point to continuing wide differentials. A typology of population and social indicators gives an indication of the small area distribution of the recent population turnaround in inner London, and of its association with other social processes such as gentrification and ethnic concentration."  相似文献

Immigration from the different regions in Spain to the Basque Country has traditionally opposed Basque and Spanish nationalism. This article provides an overview of the discourse of both nationalist traditions with respect to the intra‐regional migration movement of the second half of the twentieth century as well as of the resulting controversy. Whereas the Basque nationalist movement claims to have defended the need to integrate immigrants since the middle of the twentieth century, particularly through politics, Spanish nationalism claims that Basque nationalism has helped marginalise these same immigrants. A qualitative analysis is used to contrast this controversy by consulting the opinion of the Spanish immigrants who settled in the Basque Country and did not avail of the political integration proposed by Basque nationalism. The main conclusion is that these immigrants tend to avoid the heart of the matter of discord between both nationalist traditions, granting little importance to political and cultural elements though stressing their social integration in the Basque Country.  相似文献

National parishes represent the primary institutional response of the Catholic Church to its ethnic diversity in the United States. The national parish differs from the more common territorial parish in the definition of its membership, which comprises all Catholics in an area sharing a specific ethnic or national background. This study examines patterns in the survival of German, Italian and Polish national parishes between 1940 and 1980. Factors related to characteristics of a parish's institutional environment and of the ethnic community it serves have strongly influenced parish survival. These factors include the parish's ethnic affiliation, the size of the ethnic community it serves, the diversity of national parishes present at the local and diocesan level and the process of parish consolidation in places where an ethnic group has formed more than one parish. Through the effects of these factors, national parishes have declined at a much faster rate in the Middle West than in the Northeast, regions in which the vast majority of national parishes were originally established. Catholic ethnic diversity should thus continue to contribute most significantly to American cultural pluralism within the latter region.  相似文献

This paper investigates the elevated expectations and dramatic downturns of the Empire Cotton Growing Corporation’s African experimentation program. It follows the trials of U.4, an insect-resistant variety bred to withstand continental growing conditions, whose expansion through east and southern Africa was filled with promise but ended in disappointment. My argument has two strands. First, U.4 was a product of imperial connections. It was an amalgam of breeding knowledge accumulated in India, specialized training received in Trinidad, and specimens imported from across the empire. Transnational scientific networks were crucial to the Corporation’s initial breeding successes. Second, the story that follows suggests that imperial scientific experts did not impose the Corporation’s research goals monolithically across a wide range of African environments. Rather, Corporation scientists recognized the diversity of African environments and adapted their breeding programs to match local agro-ecological realities. I suggest that the ECGC breeding program is a story of expert knowledge that incorporated rather than undermined ecological specificity.  相似文献

Abstract: This article, based upon in-depth interviews with anti-governmentleaders and activists, first explains the significance of theupheaval in Communist Poland in 1980–1981 and articulateshow the author became involved in this research and explainshis methodology. It then concentrates on the impact on the personallives of the participants and on social relations in Polandof the upheaval that produced an unprecedented-in-the-Soviet-blocindependent union with the right to strike. It shows how activistsdeveloped talents and cultivated abilities as they assumed responsibilitiesthat had previously been unavailable to them. It examines howworkers' lives changed as they grasped control of power: theirworking conditions improved; their status rose; they treatedone another better; they educated themselves. These changes,which contributed to the context in which the political struggleof that period took place, survived the suppression of the unionand ultimately contributed to bringing about the end of Communismin Poland.  相似文献

European household structures and their geography have been transformed in recent decades as a response to the interplay of demographic events and changing lifestyles. The formation of new households generally outstrips the rate of population increase, as more numerous and smaller households result from changing patterns of marriage, child-bearing, divorce and longevity. This paper tests some of the underlying hypotheses of the 'second demographic transition' using data from the most recent (1999) French population census. It provides an analysis of changing national household structures over the last quarter of the twentieth century and highlights the importance of smaller households, with particular emphasis on the rise of living alone. Trends identified in earlier work have intensified during the 1990s. In discussing the geography of new household forms, the paper focuses particularly on the evolution of major central cities and argues for more explicit links between their distinctive population and household structures and wider socio-economic change.  相似文献
