Pauperizing the pastoral periphery: the marginalization of herding communities in the world's dry lands     

LI Ying  Douglas L. Johnson  Abdelkrim Marzouk 《地理学报》2002,12(1):1-14

Environmental degradation and other socio-economic problems are too often discerned in contemporary pastoral systems in the wake of global economic change. This paper identifies cases where pastoral people respond to external pressures and opportunities in positive ways and adapt to changes. We hope that by doing this a framework of pastoral adaptations can be developed. The first part of this paper focuses on impacts of global economic change, which are mostly negative in nature. Through an extensive literature search in geography, anthropology, range management, and development field, the second part introduces cases that we categorize as positive adaptations.  相似文献   

The Permeable City: Toronto's Spatial Shift at the Turn of the Millennium     

Betsy Donald 《The Professional geographer》2002,54(2):190-203

This article presents an analysis of the relationship between urban governance restructuring, and global, national, and local action through a case study of the Toronto city‐region. The Toronto city‐region recently underwent a massive reorganization of its governance structures, functions, and jurisdictional boundaries. This restructuring raises questions about why these changes occurred at this particular juncture in the region's history. Why did the city that had always been known in the academic and political discourse as the “city that works” stop “working”? What global and national forces might have accounted for such a radical restructuring? And what did local action contribute? These questions are explored in both historical and contemporary contexts by drawing on insights from regulation theory, urban regime theory, and an analysis of Canada's changing fiscal federalism. This approach informs the role that institutions — regardless of their origin or territorial scope — play in sustaining a local accumulation system, and how this “local” accumulation grounds a national regulatory mode and regime of accumulation. The approach also explores the relationship between regime and regulation theories in the context of policy formation and institution building. The study concludes that the current policy set is incapable of resolving the region's crisis tendencies. Notwithstanding external forces, the current policy set is not inevitable. Globalization does not predetermine all spatial‐economic outcomes.  相似文献

试论经济全球化对非洲华人经济的影响   总被引：1，自引：0，他引：1  

陈以定 《世界地理研究》2003,12(3):14-19,105

经济全球化使越来越多的国家和地区，甚至是一个经济体和一个经济单位都主动或被动地参与到世界经济中来，非洲的华人经济也不例外。鉴于目前有关华人经济的文章主要集中在东南亚地区和美国与欧洲，很少有人探讨过非洲华人经济的情况，所以本文试图通过经济全球化条件下的非洲经济、中非经济关系和华商对非洲的投资，来论述经济全球化对非洲华人经济的影响。  相似文献   

中国与周边接壤国家经贸关系探析     

汤金丽  王声跃 《云南地理环境研究》2003,15(3):48-54

2l世纪80年代以来，世界经济进入了“地缘时代”，各个国家开始重新审视周边国家和地区在本国经济中的作用和发展潜力，并致力于发展同他们的经贸关系。中国历来奉行睦邻友好的对外政策，与周边接壤国家有悠久的经贸往来^[1]。90年代以来，这种经贸往来更符合中国的利益，对它进行研究具有较大的意义。在对周边16个接壤国家中已建交的14个国家与中国经贸关系进行分析的基础上，讨论其具有的优势特征、存在的问题及解决的办法。  相似文献   

Sectoral Shifts and Occupational Migration in the United States     

Mark E. Reisinger 《The Professional geographer》2003,55(3):383-395

This research is grounded in notions of differential economic restructuring across employment sectors and geographic space, as well as migration selectivity by occupation. A series of unconstrained competing‐destinations models were employed to analyze the response by workers in thirteen occupational categories to sectoral employment change, average wages, and distance. As was hypothesized, workers in occupations that require high levels of education and skills are more responsive, in terms of migration, to economic opportunities in alternative labor‐market areas. However, the results do not support the hypothesis that highly educated and skilled workers migrate longer distances. Further investigation suggests that opportunities for highly educated and skilled workers may be clustering in relatively few areas that are in relatively close proximity.  相似文献

导/定向钻进非开挖铺设地下管线施工技术分析     

赵大军  郭威  于萍  计胜利 《世界地质》2003,22(3):309-312

导／定向钻进是一种技术密集型、对环境无害的地下管线铺设技术。通过综合经济比较分析，说明了导／定向钻进技术在管径大、埋深大的条件下所具有的明显经济优势。通过对国内外现有技术水平的比较，分析了我国在该技术发展规模、工程应用领域、新型高技术含量、钻机的工作性能等方面存在较大的差距。认为我国应在钻机的机电液一体化、施工过程自动化控制、配套泵组及泥浆系统、钻进规划软件开发等方面作进一步深入研究。  相似文献
