THE EVOLUTION OF SERVICE ECONOMIES: A GEOGRAPHICAL PERSPECTIVE1     

Aharon Kellerman 《The Professional geographer》1985,37(2):133-143

Of the several classifications of services, each emphasizes different characteristics. The International Standard Industrial Classification (ISIC) is used for a comparative study on the transformation into service economies of the U.S., Canada, Great Britain, France, West Germany, Italy and Japan. Service economies are defined as national economies in which employment in services surpassed that in manufacturing. The pace of the evolution of service economies has been rapid with North America leading, followed in order by Great Britain, France, Italy, Japan and West Germany. Service economies have important implications for urban growth, intercity competition, and international trade.  相似文献   

GMOs and their contexts: A comparison of potential and actual performance of GM crops in a local agricultural setting     

A. Wendy Russell 《Geoforum》2008,39(1):213-222

In this paper, I argue that genetically modified organisms (GMOs) have inherent potential to contribute to socially and environmentally sustainable agriculture by virtue of their ‘biological embeddedness’. Their actual ‘performance’ and how this contributes to sustainability depends on the ‘mutual shaping’ of technology and context. While much attention has been given to the design context of GMOs, this paper considers the influence of the application context and of users. A case study investigating the use of insect-resistant and herbicide-tolerant GM cotton in the cotton-growing region of New South Wales in Australia is presented. The study was based on focus groups with farmers and other stakeholders in a cotton-growing community. It demonstrated a range of direct and indirect effects of GM cotton use, both positive and negative for sustainability, and the ways in which these effects were influenced by the local social context. The influences of the biotechnology industry context, in limiting the contributions that gene technologies can make to sustainability, were also considered, and remedies suggested. I argue that the polarity of the GM debate is hindering progress on these issues, and that a more balanced approach to our analysis of GMOs is necessary in order to fully understand, and to influence, their role in the future of rural spaces.  相似文献

区域复合生态系统分析及其可持续发展对策     

杨国华  周永章  郑奔 《云南地理环境研究》2006,18(6):26-29

从系统物质循环角度分析了人类社会-经济-自然复合生态系统不可持续发展的原因是由于大量生产-大量消费-大量废弃的线性生产和消费模式耗用了大量资源，产生太多的废弃物，破坏了复合系统正常的物质代谢。提出系统调节，实现系统可持续发展的途径，包括控制人口增长，适度消费；调整复合系统生产链的数量结构和比例关系；建立协调的结构网络关系，构建循环型社会。  相似文献   

Gender and voluntary work in late adulthood in rural communities in the Netherlands     

Joos Droogleever Fortuijn  Marieke van der Meer 《GeoJournal》2006,65(4):381-392

This article discusses the involvement of older women and men in voluntary work in rural communities in the Netherlands. Gender, ageing and civil society form the core concepts in the article. Politicians and policy makers in the Netherlands are worried about the perceived decline of civil society and about the consequences of this decline for specific categories of older women in terms of well-being and social exclusion. The paper presents the results of two surveys of involvement of older women and men in civic organisations, voluntary work and local actions. The surveys indicate high levels of involvement of both women and men. No gender differences are found in activity level. However, the data demonstrate the gendered nature of civil society. Women are more engaged in informal voluntary work and informal local actions, while men are more active in formal organisations and functions. This gender segmentation is not absolute, however. Many older women and men transgress the traditional feminine–masculine boundaries. The surveys highlight the involvement of women and men in rural communities, but indicate lower activity levels in urban areas.  相似文献   

Science and the desertification debate   总被引：1，自引：0，他引：1  

David S.G. Thomas 《Journal of Arid Environments》1997,37(4):599-608

Desertification is an environmental issue that has major environmental and social dimensions, and which has been controversial in a number of respects. The recent UN Convention on Desertification and Drought places considerable emphasis on the social dimensions of the problem and the role local peoples and NGOs have to play in tackling it. When desertification first became regarded as a major issue in the 1970s, science was seen to have a major role in understanding and solving the problem, but in some circles has been regarded as failing to contribute usefully. This paper explores the nature of scientific contributions, why science may have been seen to fail to serve the needs of policy-makers, and why scientific findings may have been misinterpreted in broader circles dealing with the issue. It concludes by identifying areas where science has still a valuable role to play in an issue that is now perhaps regarded as more political and social than scientific.  相似文献

In the Critical Zone: Geography at the U.S. Geological Survey     

William L. Graf 《The Professional geographer》2004,56(1):100-108

Geography is again becoming an integral part of the premier natural‐science agency of the federal government. Geographic research emphasizes the surface of the earth, a portion of the earth system that the U.S. Geological Survey (USGS) defines as the “critical zone.” Although geography was part of the USGS from the creation of the agency, in recent years geography in the agency has largely been limited to topographic mapping. Recently, the USGS and an advisory committee of the National Research Council (NRC) reviewed the role of geography at the Survey. The committee's report, along with ongoing decision‐making in the federal government, is likely to reshape geography in the USGS. The newly defined USGS has a regional structure and four disciplines: geology, hydrology, biology, and geography. The NRC report emphasizes the need for the creation of a spatial database called the National Map to replace the existing series of paper topographic maps. The report also outlines the need for geographic research in geographic information science (GIScience), nature‐society connections, and bridging of science to decision‐making. The NRC report has been briefed throughout the USGS, in the federal executive branch, and in Congress. The changing role for geography in the USGS requires change in the agency culture, revised budgetary decisions, and the establishment of a long‐term core agenda for research. Academic geographers will need to prepare a new generation of geographers for participation in the USGS and similar agencies.  相似文献
