The Human Rights Act is the result of post-war changes in Europe. It is the consequence less of the campaigning of dedicated individuals and more of the change in the position of the United Kingdom in Europe and the world. Objections to incorporation of the Convention have given way to the desire to be like the rest of Europe. Traditional views of the judicial role have given way to a perception of the judiciary as the last bastion against an over-powerful executive, unchecked by Parliament. 相似文献

The business of bribery: Globalization, economic liberalization, and the “problem” of corruption 总被引:1,自引:0,他引:1
This paper is intended as a critical response to the emerging consensus within both academic and policy literatures that we are currently facing an epidemic of corruption which threatens to undermine the stability of economic and political development on both a national and global scale, and which requires both immediate and wide-ranging policy interventions. Based on a review of the publications and policy statements of the leading anti-corruption crusaders — namely the OECD, the IMF, and the World Bank — it will be argued that the recent concern with corruption is attributable, not to any substantive increase incorrupt practices, but rather, to the re-framing of corruption in light of broader shifts and transformations within the global economy. This revised version was published online in July 2006 with corrections to the Cover Date. 相似文献

The family of a patient who is unconscious and respirator-dependent has made a decision to discontinue medical treatment. The patient had signed a donor card. The family wants to respect this decision, and agrees to non-heart-beating organ donation. Consequently, as the patient is weaned from the ventilator, he is prepped for organ explantation. Two minutes after the patient goes into cardiac arrest, he is declared dead and the transplant team arrives to begin organ procurement. At the time retrieval begins, it is not certain that the patient's brain is dead or that cardiac function cannot be restored. Procurement follows uneventfully, and two transplantable kidneys are retrieved . 相似文献

Evaluation of Commercial Kits for Dual Extraction of DNA and RNA from Human Body Fluids, , 下载免费PDF全文
Andrew J. Schweighardt Ph.D. Courtney M. Tate Ph.D. Kristina A. Scott M.S. Kathryn A. Harper M.S. James M. Robertson Ph.D. 《Journal of forensic sciences》2015,60(1):157-165
STR typing of DNA evidence can identify the donor with a high power of discrimination but cannot identify the tissue origin of a body‐fluid stain. Using RNA to attribute a crime scene stain to a particular tissue may aid in reconstruction efforts. With blood from 10 donors, four DNA and RNA coextraction kits were evaluated by measuring yields and STR and mRNA profiles. T tests indicated some significant differences in kit performance. The Zymo Research ZR‐Duet? kit performed best based on average DNA (41.4 ng) and mRNA (4.07 ng) yields and was the only kit to provide complete DNA/RNA profiles for all samples. The consistency of this kit was challenged by data from additional blood and saliva donors. Further testing is advised before a superior kit is unequivocally chosen. Stand‐alone DNA or RNA purification generally offers higher yield, but coextraction may still allow successful STR profiling and tissue source identification. 相似文献

The Development and Application of Random Match Probabilities to Firearm and Toolmark Identification 下载免费PDF全文
John E. Murdock M.S. Nicholas D.K. Petraco Ph.D. John I. Thornton D.Crim. Michael T. Neel M.S. Todd J. Weller M.S. Robert M. Thompson B.S. James E. Hamby Ph.D. Eric R. Collins B.S. 《Journal of forensic sciences》2017,62(3):619-625
The field of firearms and toolmark analysis has encountered deep scrutiny of late, stemming from a handful of voices, primarily in the law and statistical communities. While strong scrutiny is a healthy and necessary part of any scientific endeavor, much of the current criticism leveled at firearm and toolmark analysis is, at best, misinformed and, at worst, punditry. One of the most persistent criticisms stems from the view that as the field lacks quantified random match probability data (or at least a firm statistical model) with which to calculate the probability of a false match, all expert testimony concerning firearm and toolmark identification or source attribution is unreliable and should be ruled inadmissible. However, this critique does not stem from the hard work of actually obtaining data and performing the scientific research required to support or reject current findings in the literature. Although there are sound reasons (described herein) why there is currently no unifying probabilistic model for the comparison of striated and impressed toolmarks as there is in the field of forensic DNA profiling, much statistical research has been, and continues to be, done to aid the criminal justice system. This research has thus far shown that error rate estimates for the field are very low, especially when compared to other forms of judicial error. The first purpose of this paper is to point out the logical fallacies in the arguments of a small group of pundits, who advocate a particular viewpoint but cloak it as fact and research. The second purpose is to give a balanced review of the literature regarding random match probability models and statistical applications that have been carried out in forensic firearm and toolmark analysis. 相似文献
