Sovereignty remains the key concept and principle accordingto which the world is ordered. But sovereignty is also a disputedconcept and a contested social practice; it has come under fierceassault from a number of diverse sources. Sovereignty is paradoxicalin nature and hypocritically practised. States have differentempirical degrees and qualitative types of sovereignty, rangingfrom the merely formal to the substantial to the popular. Statesalso have different dispositions towards sovereignty, and areliable to project their own in different ways in pursuit ofconflicting objectives. Different groups of states attempt toimpose their understandings and beliefs on the internationalsystem. There are three ideal types which help us to understandthe issue of sovereignty and the interactions of sovereign states.These are respectively Westphalian, liberal and anti-utopian.The Westphalian paradigm has the maintenance and protectionof state sovereignty as its key concept. The liberal paradigmis conceived in terms of the concept of popular sovereigntyand controversies over the extent to which this ideal shouldbe promoted and exported. The anti-utopian paradigm is conceivedin terms of the concept of quasi-sovereignty or the loss ofsovereignty, and in terms of resistance to attempts to imposeglobalization and liberal values on recalcitrant states andcultures. 相似文献

A pesticide poisoning victim suspected initially as having died a natural death was autopsied. The victim was a 47-year-old male. Macroscopically, signs of acute death and, in particular, general erosion in the mucosa of the airways and esophagus were observed. In the gastric contents, which had a pungent smell and a greenish-brown color, 5.00 g/L of propanil, 1.27 g/L of carbaryl, 0.38 g/L of ethylbenzene, and 0.32 g/L of xylene were detected. In the blood (serum), 21.6 mg/L of propanil, 8.1 mg/L of carbaryl, 1.7 mg/L of ethylbenzene, and 4.0 mg/L of xylene were identified. Postmortem methemoglobinemia (45%) was recognized. The cause of death was considered to have been pesticide poisoning; propanil was probably most responsible for his death. The police considered the case to be "death with illness as the suspected cause." By performing an autopsy, however, we were able to clarify that the cause of death was pesticide poisoning. 相似文献

A five-year-old boy was fatally injured by a stab and a cut to the throat. The suspected offender, an acquaintance of the victim's mother, stated that he had been disturbed by the boy while attempting suicide and had therefore killed the boy. The suspect showed superficial cuts on both wrists and three shallow stabs on the right-hand side of the abdomen. The purpose of the forensic investigations was to answer the question if the suspect's statement could be confirmed or if the attempted suicide took place after killing the boy. The blood-smeared blade of the knife was divided into different sectors with the cutting edge and the tip of the blade being examined separately from the sides. The blood traces from the different blade sectors were then typed in 12 different DNA regions by PCR (polymerase-chain-reaction). It could be demonstrated that the strong blood traces on the sides of the blade originated from the victim alone, whereas in the area of the edge and the tip of the blade the amount of the victim's blood was negligible compared with that of the suspected offender. The explanation for this finding is that in the areas of the edge and the tip of the knife the blood of the victim must have been replaced by the blood of the suspected perpetrator, which means that the suicidal injuries were the last to be caused by the knife. 相似文献

Medical training in the United States often takes the form of a grueling endurance test in which patients are often those most at risk. This Article discusses sleep deprivation among resident physicians in the United States with an eye towards resolving the problem through legal channels. It analyzes the effects of sleep deprivation on resident physicians, with subsequent discussion of the implications for patient care and medical training. Next, it makes comparisons to medical training in other developed nations, as well as regulations that exist in the airline and trucking industries, where public safety is a principal concern. Furthermore, this Article discusses proposals to mend the dilemmas created by sleep-deprived resident physicians through statutory and regulatory reform, deterrence by way of tort law, and unionization or collective bargaining. 相似文献

The authors are privileged to have been provided with correspondence about a dispute over the ongoing storage of genetic material (as Guthrie Cards) in Victoria. The correspondence details confusion over the roles of government and the private sector service provider in accounting for the storage, use and destruction of these stored genetic materials collected as part of a government public health program. The purpose in publishing this account is to highlight the present inadequacies in current practices and the ongoing potential for a crisis in the management of collected genetic materials through a lack of appropriate regulation, transparency and accountability. The article suggests measures to remedy some of the existing inadequacies in contractual arrangements and recommends that the government retain ownership and control of both the genetic materials and the derived information to ensure some accountability in the present legal environment. 相似文献
