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

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

This article explores theoretical and empirical issues in the application of clinical neuropsychological evidence to forensic issues in the criminal law. The nature of forensic neuropsychological evaluations is discussed with reference to issues of competency to stand trial, criminal responsibility, and other competencies in the criminal process. Examples of specific disorders relevant to criminal law standards are presented, together with data estimating the prevalence of brain dysfunction in criminal and forensic populations. Research is also reviewed on the role of neuropsychological brain dysfunction in the etiology of violence and criminally relevant behavior. Finally, empirical and ethical issues concerning the applicability and admissibility of forensic neuropsychological data in the criminal context are discussed.  相似文献

Technology policies and their effect on technology transfer from defense to civilian industries in Israel from 1967 to 1995 are explored. Defense technology policy is found to drive the growth of the defense industry and to limit defense conversion to commercialization initiatives developed primarily through intra-organizational technology transfer. The case of the Israel Aircraft Industries (IAI) is presented. Also the development of national technology policy in Israel is traced and found wanting. Civilian and defense technology policies are found to be uncoordinated with each other and together are incapable of producing interorganizational technology transfer so as to significantly effect defense conversion on a wide number of economic actors particularly small firms. To achieve a socially effective defense conversion process (in which technologies are transferred from defense firms to many economic actors), the analysis suggests that a national technology policy should be designed and implemented under Prime Minister's leadership.  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

Optimal Law Enforcement with a Rent-Seeking Government   总被引:1,自引:0,他引:1  
This article analyzes public and private law enforcement whenthe government is motivated by rent seeking. A rent-seekinggovernment seeks primarily to maximize revenue. The articleconcludes as follows: (1) if offenders have sufficient wealth,a rent-seeking government is more aggressive than a social-welfare-maximizinggovernment in enforcing laws against minor crimes (such as parkingviolations) but more lax in enforcing laws against major crimes;(2) competitive private enforcement is usually better and neverworse than monopolistic private enforcement; (3) The choicebetween competitive private enforcement and public enforcementdepends on which is cheaper and on the severity of the offense.  相似文献
