In May 2005, the World Health Organization adopted the new InternationalHealth Regulations (IHR), which constitute one of the most radicaland far-reaching changes to international law on public healthsince the beginning of international health co-operation inthe mid-nineteenth century. This article comprehensively analysesthe new IHR by examining the history of international law oninfectious disease control, the IHR revision process, the substantivechanges contained in the new IHR and concerns regarding thefuture of the new IHR. The article demonstrates why the newIHR constitute a seminal event in the relationship between internationallaw and public health and send messages about how human societiesshould govern their vulnerabilities to serious, acute diseaseevents in the twenty-first century.  相似文献

In this article we explore how much state is necessary to make governance work. We begin by clarifying concepts of governance and the “shadow of hierarchy” and we follow this clarification with a brief overview of empirical findings on governance research in developed countries. We then discuss the dilemmas for governance in areas of limited statehood, where political institutions are too weak to hierarchically adopt and enforce collectively binding rules. While prospects for effective policymaking appear to be rather bleak in these areas, we argue that governance research has consistently overlooked the existence of functional equivalents to the shadow of hierarchy. We assert that governance with(out) government can work even in the absence of a strong shadow of hierarchy, we identify functional equivalents to the shadow of hierarchy, and we discuss to what extent they can help overcome issues of legitimacy and effectiveness in areas of limited statehood.  相似文献

Hair analysis has been presented by some authors as a possible tool of investigation for estimating patients' compliance to long-term therapies. This paper summarises the different publications that have been devoted to this topic and highlights the available statistical data presented to support this proposition. Qualitative results of such determinations may be of some interest but due to the enormous interindividual variations of quantitative data, the idea of using hair analysis to ascertain whether a patient has taken his treatment exactly as prescribed, clearly appears to be inapplicable.  相似文献

The fingernail ridge patterns of a pair of identical twins were compared to each other, their parents, and an unrelated subject. The patterns of the twins' nails showed regions of strong similarity but were distinguishable from one another. Fewer similarities were found when comparing the nails to those of the parents and the unrelated control. The twins were shown to be monozygotic by means of DNA profiling. This therefore represents the first demonstration of unique fingernail ridge patterns in subjects shown conclusively to be identical twins. When the fingernail ridge patterns were examined with a scanning electron microscope, the backscattered electron (BEI) images were found to have superior contrast when compared to the secondary electron (SEI) images.  相似文献

The analysis of naphthenic acid revealed that they may be used for tin detection in the cadaveric material due to their high complex-forming ability. Method of extraction-atomic absorption tin determination in human organs was developed on the basis of naphthenic acid use. Modified method which differs from the common one by higher sensitivity and selectivity is presented.  相似文献
