This paper develops a multiobjective mathematical location model to identify possible locations for environmentally hazardous facilities. Risk and equity are recognized as the most important criteria in determining site selection. In contrast to earlier models, the equity objective explicitly considers the existing distribution of environmental burdens when siting new hazardous facilities. Proposed environmentally hazardous facilities are located so that the burdens associated with new and existing hazards are shared as equally as possible among all areas. The application of the model, in a case study of the Greenpoint/Williamsburg neighborhood in Brooklyn, New York, illustrates the trade‐offs associated with various risk and equity scenarios. Sensitivity analyses demonstrate how the existing distribution of environmental burdens may act as a constraint and limit the degree of equity that may be obtained when locating new facilities. 相似文献

A relatively closely spaced set of unpegged mortise-and-tenon joints was the significant element revealed in the 7th-century AD shipwreck, Dor D. It provides additional information for the transitional period of shipbuilding in the Mediterranean, and together with additional wrecks it establishes a better database for ship construction in the 4th–11th centuries AD. The preliminary conclusions tend to draw a slightly more complicated picture of the general evolutionary trend, since they present some features that have traditionally been considered as a disappearing technique. 相似文献

Despite widespread public interest on the topic of whaling, there is at present relatively little work on how philosophy might contribute to analysis of the status of whaling in international law. When philosophers have looked at the topic of whaling, they have confined their attention to a fairly narrow set of ethical questions, such as whether international law should permit certain forms of traditional indigenous whaling or extend legal rights to whales themselves. However, there is another important issue which has so far been largely neglected by philosophy, even though it is at the forefront of current international legal disputes over the status of whaling: the issue of so-called ‘scientific whaling’. This article considers the international legal dispute between Australia, New Zealand and Japan over the latter’s lethal harvesting of whales in the Southern Ocean, and the recent attempt at resolution by the International Court of Justice. On its face, this required that the Court demarcate ‘scientific’ from ‘unscientific’ activity; however, it effectively baulked at this task. The authors argue that this approach of the Court was unfortunate, and that demarcating science from commerce is not only achievable in philosophy, but might also inform international legal practice. Resolving this issue is important for genuine progress to be made in the current international stand-off over Japanese whaling in the Southern Ocean. 相似文献

The fact that agricultural policy decisions can have important environmental consequences has become common knowledge among policy scholars and policy practitioners. This relationship is reflected in the increasingly prominent soil conservation and environmental protection components of the 1985 and 1990 Farm Bills. In debating the value of continuing these provisions in the upcoming reauthorization of this legislation, scholars and politicians alike focus almost exclusively on their water quality benefits. However, the soil conservation components of agricultural policy also may affect air quality significantly. Using multivariate transfer function analysis, we find that implementation of the 1985 Farm Bill's Conservation Reserve Program has improved air quality significantly in that area of the country most plagued by agricultural air pollution. 相似文献

Environmentally Sensitive Areas (ESAs) designated under EC Structure Regulation 797/85 now cover 1.4 million ha of the Scottish countryside and are likely to make a substantial contribution to the regulation of landscape change. Visual changes to landscapes with (policy on) and without (policy off) the ESA programme in two Scottish ESA areas, Breadalbane and the Machair, are predicted through impact-assessment procedures and computer manipulation of photographic images. The methodological requirements for such predictions are outlined and substantial differences in landscape characteristics under policy on/off scenarios are revealed. Such approaches to landscape change are an essential foundation for the development of environmental cost-benefit analyses and will contribute to public consultation processes. 相似文献
