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

Change is a feature of life in all communities and results in heightened demands being made of individuals and organizations alike. In the school setting administrators and classroom teachers have to respond to a great variety of demands that change has brought. Accountability, in various guises, is one area where changes in societal attitudes have resulted in greater demands being exacted of all professions including that of teaching. In this regard legal accountability is of considerable concern to schools as legal matters increasingly impact on school policies, practices and procedures. In this article research into the relationship between the law and school leadership and management is explored. A brief overview of research into school management and principals as leaders is followed by a discussion of the need for knowledge of areas of law impacting on schools. The article concludes that in order to ensure a school's legal safety, a preventive legal risk management culture is needed.  相似文献

Canada's imprisonment rate has not changed appreciably since 1960. This stability contrasts with the increased imprisonment rates experienced by Canada's most obvious comparators—the United States and England and Wales. We examine this divergence and propose several interrelated explanations for Canada's anomalous pattern. While Canada is shown not to be immune to pressure for harsher practices and policies, it has been able to counter or balance these trends with other more moderating forces. In particular, we suggest that Canadians have largely been able to escape several of the wider forces or "risk factors" at the root of higher incarceration in other countries. Further, we suggest that certain protective factors of a historical, cultural, and structural nature can also be identified that have limited the extent to which Canada has adopted the same punitive policies documented in the United States and England and Wales.  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

In this paper we examine one of the areas where there is a marked difference between Civil and Common contract law, that of the enforcement of liquidated damages and more particularly of penalty clauses. Common law judges are quite reluctant to enforce liquidated damages, especially if they believe that they include penalty clauses which are not enforceable. On the contrary, in almost all European contract laws liquidated damages are readily enforced, as are penalty clauses when they are not manifestly excessive. Although most law and economics scholars have criticized Common law courts for the non-enforcement of penalty clauses, there is a sizable minority of scholars who have defended the Common law “non-enforcement” policy on the ground that penalty clauses are inefficient because they hinder efficient breach. However, and despite the merits of the arguments advanced by advocates of the non-enforcement of penalty clauses, we believe that Common law’s rejection of penalty clauses is inefficient. We further show that the Civil law solution to the problem is not only comparatively more efficient, but that it can also appease the worries of those scholars who are afraid that efficient breaches will be deterred. The solution that Civil law systems give to the problem manages to enforce the parties’ wishes and to avoid deterring efficient breaches. However, we point out that in order for the Civil law systems to take advantage of this superiority, the interpretation of their Civil Codes should be guided by economic analysis and the respect to the wishes of the contracting parties.  相似文献
