"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

Factors affecting regional differences in population growth in the United States are explored. "In this study, we estimated the contributions of births, deaths, and migration to changes in population size between 1950 and 1980 for the 48 contiguous states in the United States. We found that population momentum (i.e., the growth that would occur in a closed population if fertility and mortality rates remained constant) had the largest effect on population growth in most states, but that differences in net migration were the major cause of state-to-state differences in growth rates. We also found that net migration has been gaining in importance compared to natural increase as a component of population growth. We expect this trend to continue in coming decades." This is a revised version of a paper originally presented at the 1988 Annual Meeting of the Population Association of America (see Population Index, Vol. 54, No. 3, Fall 1988, p. 429). 相似文献

面对突如其来的石油危机 ,日本首先在对外政策上采取稳住石油供应对策 ,放弃对阿以冲突的“中立”政策 ,采取支持阿拉伯国家的“亲阿拉伯”政策 ,加强同中东产油国关系。随着石油危机的缓解 ,日本又积极开展国际合作 ,与西方石油消费大国共同合作避免石油危机再度袭来。与此同时 ,日本在对内政策上大力开展调整主要产业结构对策 ,放弃以重化学工业为主的产业结构 ,发展低能耗、高科技产业 ,力争从根本上摆脱石油危机的困扰。 相似文献

20世纪80年代以来世界环境问题与环境保护浪潮分析 总被引:1,自引:0,他引:1
20世纪的帷幕已然落下,对20世纪的反省却方兴未艾。人们从许许多多的角度对之加以描述或定位。有人认为20世纪是“全球规模环境破坏的世纪”。这一说法其实并不为过。虽然环境问题由来已久,但大规模、高速度的生态环境恶化趋势,只是近一个世纪以来、特别是二战后出现的现象,而非历史的常态。 相似文献

This article considers the incorporation of part of Britain into the Roman empire in the context of globalization theory and world-systems history. Emphasis is placed on the local effects of the expansion of global systems and their impact on the social practices of eating and drinking at a range of settlements in the southeast of Britain in the Iron Age to Roman transition, c. 50 BC–AD 200. Through the analysis of consumption practices via quantitative pottery assemblage data, it is argued that globalization offers a more sophisticated framework to describe change than current archaeological approaches to Romanization and identity. The results show that while much of the populace was subject to a progressively homogenizing supply of food-related pottery vessels, the use of such technologies was negotiated within social practices drawing on the integration of both local and global cultural elements. Such findings highlight the potential of critical applications of globalization theory to conceptualize economic, social, and cultural changes in Roman provincial societies. 相似文献

"文革"结束后至当代中国研究所成立前,是国史研究学术建制的探索完成时期.这个时期,国史研究学术建制的发展历程大致分三个阶段:第一阶段,自"文革"结束至中共十一届三中全会开始前,胡乔木提出"赶快着手研究"中华人民共和国史,中国社科院成立现代史研究室;第二阶段,中共十一届三中全会结束后至1982年底,编写《当代中国》丛书启动,中国社科院拟成立现代史研究所的建议未被采纳;第三阶段,自1983年至1990年底,以当代中国研究所成立为标志,国史研究学术建制取得实质性进展.学界在探索完成国史研究学术建制的十余年时间里,始终贯穿着明确的学术自觉意识.这是完成国史研究学术建制的重要思想保证. 相似文献

In March 1983 the new Labor government was in a position to implement its health policies, including its promised revival of the community health program. Although funds were allocated, substantive issues of policy remained. Various parties at interest could agree on general principles but differed on operational meanings, means, and priorities. Seventy‐five groups whose leaders were interviewed devised an array of organizational strategies to influence policy development. These included reworking their own priorities and internal structures, developing media strategies, and changing their relations with outside organizations. The more successful groups, at least in the short term, tended to be older and larger. 相似文献

水资源短缺一直制约着京津唐地区经济和社会的发展。20世纪70年代,因缺水引发的经济、社会问题逐渐凸显,促使中央和地方政府开始考虑实施跨流域调水工程。引滦工程作为北方最大的跨流域调水工程,其决策经历了曲折的过程。1958年,北京和唐山曾分别提出引滦河水的设想,唐山还实施了引滦入还和引还入陡工程。1972年,海河流域大旱促使中央做出加快实施引滦工程的决定,但由于地质情况复杂等原因,引滦工程设计方案被反复修改。1981年,天津提出了单独引滦济津路线并得到了中央的支持。引滦工程对缓解京津唐用水紧张发挥了重要作用,天津是引滦工程受益最大的地区。 相似文献

Leo S. Klejn 《Norwegian Archaeological Review》2013,46(1):9-13
In the author's view the contemporary detente and the spirit of Helsinki may spread historical optimism like that established after the end of World War I. The likeness of mentality leads to a retreat in fashion everywhere, and archaeology will hardly be an exception. Like some others the author also predicts an archaeological structuralism and considers its possible realization with respect to the ‘damned question’ of archaeology ‐ the change of cultures. There has here been sounded an unexpected call to dig less, and one more expected ‐ to theorize more. 相似文献
