At the annual meeting of the Society of Hair Testing in Vadstena, Sweden in 2006, a committee was appointed to address the issue of guidelines for hair testing and to assess the current status of accreditation amongst laboratories offering drug testing in hair. A short questionnaire was circulated amongst the membership and interested parties. Fifty-two responses were received from hair testing laboratories providing details on the amount and type of hair tests they offered and the status of accreditation within their facilities. Although the vast majority of laboratories follow current guidelines (83%), only nine laboratories were accredited to ISO/IEC 17025 for hair testing. A significant number of laboratories reporting that they were in the process of developing quality systems with a view to accrediting their methods within 2-3 years. This study provides an insight into the status of accreditation in hair testing laboratories and supports the need for guidelines to encourage best practice.  相似文献

The article evaluates the concept of ‘developmental’ policies, comparing post-communist Russia and Sub-Saharan African (SSA) states. Asian ‘developmental state’ policies have been identified as developmental because of successful industrial policies and leaders’ ability to implement them. The comparison shows that while these features have been absent in SSA, notably due to the trapping effects of commodity dependence, Russia exhibits an original dualistic model where the negative impact of commodity dependence (such as the creation of rents) is compatible with developmental industrial policies. The evidence presented demonstrates the importance of constraints that stem from both economic and political structures, in turn explaining variations in developmental policy effectiveness.  相似文献

Abstract. There is tension between the adversarialism of the U.S. legal culture and the investigative procedures of the sciences, and between the law's concern for finality and the open‐ended fallibilism of science. A long history of attempts to domesticate scientific testimony by legal rules of admissibility has left federal judges with broad screening responsibilities; recent adaptations of adversarialism in the form of court‐appointed experts have been criticized as “inquisitorial,” even “undemocratic.” In exploring their benefits and disadvantages, it would make sense to look to the experience of other legal systems.  相似文献
