After the Agreement on the Trade-Related Aspects of Intellectual Property Rights (TRIPS) came into operation in 1995 developing countries have found themselves in a process of continual negotiation over intellectual property rights and access to medicines. These negotiations have taken place in the World Trade Organization and in the context of free trade agreements. The paper suggests that the only real win for developing countries has been the Doha Declaration on the TRIPS Agreement and Public Health in 2001. What have been the lessons for developing countries in a decade of negotiations over access to medicines? Drawing on themes of rule complexity and regulatory ritualism the paper discusses four key lessons for developing countries. It concludes by arguing that developing countries will do better if they adopt a networked governance approach to negotiation rather than continuing to rely on traditional coalition formation.  相似文献

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.  相似文献

Archibald T. Strong, born in Melbourne, was the son of an Australian scholar who went to an academic post at Liverpool. The younger Strong received his secondary and tertiary education in England. There, he became proficient in modern European languages and literature. He initially planned a career in the law, but for health reasons returned to Australia to the Department of English at the University of Melbourne. Prior to the First World War, Strong became prominent in Melbourne literary circles and also a prolific commentator on world affairs. As an early member of the Round Table group in Australia, Strong assessed Imperial Germany as posing an existential threat to the British Empire and hence to Australia's security. The nation's future, he believed, lay in unwavering defence of the Empire. Strong evinced a distinct impatience with fellow citizens, especially on the socialist left, who failed, in his view, to understand the realities of Australia's position in the world and what was at stake in the Great War.  相似文献

This paper explores the multi-layered representations of violence and crime in the recent Hollywood film Gangs of New York [Scorcese (2003) Miramax]. We use our exploration of this film to suggest that popular culture, even through its most mainstream products, can be seen as a critical criminological space where alternative views of law, crime and the state are made available. Rather than understanding Hollywood movies simply as vehicles for disseminating conventional mores, we suggest that they can furnish critical (and complex) points of view on law and crime and that the project of a critical criminology can be strengthened by engaging more forthrightly with these ubiquitous cultural forms.  相似文献

Decomposition studies were conducted using two carcasses of domestic pigs, Sus scrofa L., 8.4 kg and 15.1 kg in weight, to determine the effects of carcass size on the rate of decomposition, composition of the arthropod fauna, and succession patterns. A total of 46 arthropod taxa were recovered during this study. No size-related differences were observed between carcasses with respect to composition of the arthropod fauna or patterns of succession. A greater number of arthropods were observed attracted to the 15.1-kg carcass, and the rate of decomposition observed was more rapid for the 15.1-kg carcass than for the 8.4-kg carcass. Internal temperatures of the 8.4-kg carcass were more directly related to external ambient temperatures during the fresh and bloated stages of decomposition. During the decay stage, both carcasses generated internal temperatures significantly above ambient temperatures. Following this stage, internal temperatures fell to approximate ambient temperatures during the postdecay and remains stages.  相似文献
