In the Democratic Republic of Congo, only an estimated 2% of all AIDS patients have access to treatment. As AIDS treatment access is scaled-up in the coming years, difficult rationing decisions will have to be made concerning who will come to gain access to this scarce medical resource. This article focuses on the position, expressed by representatives of Médecins sans Frontières (MSF), that the practice of AIDS treatment access rationing is fundamentally unethical because it conflicts with the ideal of universal treatment access and the human right to health. The conclusion is that MSF's position lacks coherence, has negative practical implications, and is unfair to governments struggling to increase patient's access to AIDS treatment in unfavorable circumstances. 相似文献
The last decade has seen growing concern at the uncertain effectiveness of most fisheries assessment and management approaches as reflected by trends in global landing statistics published by FAO. These imply full exploitation of the majority of fishery resources and a serious overcapitalization of fleets at the global level. Projected increases in demand, future prices for fisheries products, and impacts of growing world populations on the ecosystem all require an urgent search for improved management frameworks.Improved management of fisheries requires, first, an understanding of the axioms and working assumptions underlying the current approaches and how these evolved in response to regional or local conditions and target species. This should promote integration of methodologies which better reflect local situations and can be expressed in the form of one or more working paradigms. These paradigms should incorporate ecosystem considerations, including environmental fluctuations and socio-economic factors. They should not assume that current production levels are independent of natural fluctuations and human impacts and should recognize the dangers of maintaining open access to marine resources throughout their seasonal cycle, life history and distribution range.Wide-use management paradigms incorporating explicit user rights, participatory management and inputs from a variety of disciplines and stakeholders are becoming popular, but must operate within a hierarchy of pre-negotiated responses to pre-specified limit reference points so that social and economic options are not lost because conservation issues have not been given precedence.Academic and research institutions could aid the management process by more participation, by promoting interdisciplinary teamwork with stakeholders and by breaking down excessive specialization and regionalization within fisheries studies. On the management side, the key elements for improving the situation seem to be consultative management frameworks that explicitly incorporate watchdog functions and implement precautionary approaches to management. Risk-averse strategies are appropriate but, given the high level of uncertainty that managers face with natural systems, fail-safe management with redundancy, both in the data sources they rely on for fishery performance and in the management measures applied, seem appropriate.For near-shore resources, governments could consider partly devolving management responsibility to appropriate levels in society, involving coastal communities, individual use rights and other vehicles for allocating access. Changing emphasis of modern technology from fisheries exploitation to improved management will be one aspect of successful future management systems, perhaps incorporating geotemporally defined access rights to near-shore and shelf resources.Recent international agreements, including the formal ratification of the Law of the Sea, show that governments are prepared for more ecologically appropriate approaches. The key stake of the fisheries industry in sustainable fisheries development needs supporting, particularly for developing countries, now the major source of aquatic marine products. High priorities for management of marine resources are rebuilding depleted resources and restoring habitats, with concern for maintaining genetic and ecological diversity. There will be a need to consider impacts of global trade on conservation of resources for future generations, if proper management is to be maintained in the face of growing demand.International agreements of relevance to future management paradigms which are compatible with the Law of the Sea Convention (and each other), include Agenda 21 of UNCED, the Biodiversity Convention, the UN Agreement on Straddling Fish Stocks and Highly Migratory Fish Stocks, the Compliance Agreement and the FAO Code of Conduct for Responsible Fisheries. Such agreements, ratified or now open for signature, provide a comprehensive basis for future customary law that can assist authorities in constructing appropriate management frameworks. Current concern remains with application of these agreements in international waters, where limited access as required for proper management still has not been established. 相似文献
Background. Helicobacter pylori (H. pylori) infection has been linked to gastritis, diarrhea, peptic ulcers, failure‐to‐thrive, anemia, as well as predisposition to gastric malignancies. Because many internationally adopted children have diarrhea, failure‐to‐thrive, and anemia on arrival to the US, we determined the prevalence of HP antibodies among these children. Methods. Serum samples from 226 unselected children from 18 countries who were evaluated in the International Adoption Clinic at New England Medical Center were tested for antibodies to H. pylori. The results of serologic screening were analyzed in relation to age at adoption, site of residence prior to adoption, weight and height, and the presence or absence of anemia, diarrhea, or intestinal parasites. Results. 31% of internationally adopted children had antibodies to H. pylori. The presence of H. pylori‐antibodies was associated with residence in an orphanage (vs. foster care) prior to adoption, older age at adoption, and coinfection with intestinal parasites. No direct effects on height or weight were identified; no associations with diarrhea or anemia were found. Conclusions. Internationally adopted children have a high incidence of exposure to H. pylori, as diagnosed serologically. Residence in an orphanage (compared with foster care), older age at adoption, and coinfection with intestinal parasites were more common among children seropositive for anti‐H. pylori antibodies. 相似文献
1. 1. For the scientific evaluation of thermal environment in relatin to human health and comfort, a number of indices have been proposed in the recent 70 years.
2. 2. However, even the newest indices are still not sufficient to explain the general thermal environment for all people including infants, the aged, the disabled etc., because such indices are based more or less on experiments using college age persons.
3. 3. Series of studies to find required thermal conditions for the disabled and the aged have been carried out from 1976 in Japan and from 1988 in Hungary.
4. 4. In 1990, the Japanese and Hungarian research groups have collaborated in an international joint experiment on the thermal environment for the disabled.
5. 5. This paper reports on the results from the first step examinations of the data from above mentioned joint experiment.

Ecological problems — because they involve interactions and interfaces — require for their solution a flexible, interdisciplinary approach. Ecological research can best be supported in an international, intergovernmental framework, but, at first sight, the requirements of such a framework may seem unwieldy to traditionally trained natural and social scientists. Experience acquired in implementing UNESCO's Man and the Biosphere (MAB) Programme indicates that it is possible to overcome the difficulties of conducting integrated research and to achieve internationally comparable results. The MAB Programme is a good example of both the potential and the limitations of integrated, international ecological research programs. There seem to be three imperatives for success: (1) research must be problem oriented, (2) the. unit selected for study must be sufficiently comprehensive and based on human use systems, and (3) research workers in various natural and social science disciplines and the administrative decision-makers must share responsibility for planning and execution. 相似文献
This article looks at the AIDS-related controversy surrounding the experiments on and the availability of medicines in southern
countries. It situates these debates in a longer-term history of transnational medicine. It highlights the rise of
international therapeutic modernity at the beginning of the 1990s, based on the strict regulation of clinical trials and on the formalization of the international
ethical rules governing experiments. This rise helped to change radically the reception of experiments conducted in southern
countries around AIDS. With regard to this new ethics applied to clinical trials in southern countries, this article goes
on to demonstrate the confrontation at the end of the 1990s between two different approaches to the universalization of healthcare.
Finally, it shows how new laws on international trade have reinitiated this confrontation. Through this story, the article
suggests in what sense the study of the political transformations of transnational medicine could offer a new field of investigation
for the social sciences. 相似文献
Many guidelines for international research require that studies be responsive to host community health needs or health priorities. Although responsiveness possesses great intuitive and rhetorical appeal, existing conceptions are confusing and difficult to apply. Not only are there few examples of what research the responsiveness requirement permits and what it rejects, but its application can lead to contradictory results. Because of the practical difficulties in applying responsiveness and the danger that misapplying responsiveness could harm the interests of developing countries, we argue that responsiveness should be refocused in three ways: in terms of (1) who enforces it, (2) under what standard, and (3) in what cases. We conclude that responsiveness should be applied by host country officials at the policy level with the exercise of judgment when externally funded research threatens to displace scarce local resources. 相似文献
