The DNA commission of the International Society of Forensic Genetics (ISFG) was convened at the 21st congress of the International Society for Forensic Genetics held between 13 and 17 September in the Azores, Portugal. The purpose of the group was to agree on guidelines to encourage best practice that can be universally applied to assist with mixture interpretation. In addition the commission was tasked to provide guidance on low copy number (LCN) reporting. Our discussions have highlighted a significant need for continuing education and research into this area. We have attempted to present a consensus from experts but to be practical we do not claim to have conveyed a clear vision in every respect in this difficult subject. For this reason, we propose to allow a period of time for feedback and reflection by the scientific community. Then the DNA commission will meet again to consider further recommendations.  相似文献

The legal file     
In this essay I examine the criminal defense file. I argue that being a largely neglected “object” of the legal field, upon a close examination, the file discloses its intriguing materiality as what is predicated on the structure of the fold that allows for the objective, virtual, and narrative spheres to overlap in a specific act-object, which, with Gilles Deleuze, I call objectile. A subsequent phenomenological analysis of the legal file as objectile shows how its constitutive features help the attorney shape ordinary matters into plentiful matters, turning the file into a locally designed sign system. Once exposed, this system reveals its relations to the legal system at large, with individual activities, institutional practices, and legal procedures all being a part of a complex manifold that is law.  相似文献

Local government reforms in contemporary Russia are placed in the broader contexts of political reform under Putin and the historical relationship between local administration and the state. Reforms of local government thus help illuminate the architecture of contemporary state building in Russia and the degree to which contemporary Russia perpetuates political traditions. This study reviews the antecedent action in local government prior to the Putin era. It then examines the Kozak Commission and the new law on local government, assessing the strengths and weaknesses of these reforms. Finally, this study examines the challenges of implementing the reforms and what these challenges tell us about devolution and centralisation under Putin.  相似文献

This study examines changes in the rate of offending in a sample of 8,834 males whose official juvenile law-violating careers included 26,650 offense episodes between ages 8 and 17 The rate of offending of active offenders (i.e., lambda) varied substantially as a function of age, increasing monotonically with age. Lambda, however, was not related to the age at first offense. In fact, the average lambda was amazingly constant at each individual age level regardless of the age at which offending began or desisted. Results are discussed in the light of age-crime curves known from other data sets and from the perspective of developmental changes in the rate of offending as youths grow older.  相似文献
