5种免提取试剂盒检验滤纸血痕结果的比较

目的探讨5种免提取试剂盒对滤纸血痕样本检验的效果。方法陈旧滤纸血痕(存放时间12～14个月)及新鲜滤纸血痕(存放时间小于1个月)各920份,分别随机分为5组。应用AGCU 17+1、Goldeneye 20A、Powerplex16HS、Identifiler Plus、Identifiler Direct 5种免提取试剂盒进行检验,对比各组检验结果。结果陈旧滤纸血痕5种试剂盒的检验成功率为98.91%～100%,各组间无差异(P>0.05);新鲜滤纸血痕,Identifiler Plus和Identifiler Direct试剂盒检验成功率高于AGCU17+1、Goldeneye 20A及Powerplex 16HS试剂盒(P<0.01);将样本做陈旧化处理后再用成功率较低的3种试剂盒进行检验,成功率分别升至100%、99.46%、99.46%;Identifiler Plus试剂盒扩增循环27次效果优于28次。结论本文5种试剂盒均可用于滤纸血痕的直接扩增检验,但使用AGCU17+1、Goldeneye 20A及Powerplex 16HS试剂盒需将新鲜血痕做陈旧化处理;Identifiler Plus试剂盒需将循环次数降为27次。     

脑外伤认知障碍者神经心理学评价研究

目的探讨神经心理学检测指标在脑外伤者认知功能障碍评定中的应用价值。方法对脑外伤后认知障碍者进行中国修订韦氏成人智力量表、韦氏记忆量表及计算机化神经行为评价系统部分项目等神经心理学检测,按照原发性损伤程度和专家鉴定结论分别编组,对检测结果进行分析。结果损伤程度组填图、长时记忆、瞬时记忆、视觉保留及视简单反应时项目得分,轻型组高于中、重型组(P<0.05),其余项目(木块图、知识、相似、曲线吻合及数字筛选)组间差异无统计学意义。专家鉴定组中长时记忆、瞬时记忆、视觉保留、视简单反应时、曲线吻合及数字筛选得分值随认知功能障碍程度加重而逐渐降低,其中前4项组间差异具有统计学意义(P<0.05)。而韦氏智力测验4个项目较轻组与较重组得分接近,且均低于中度组,其中3项得分比较具有统计学差异(P<0.05)。结论原发性脑外伤与认知障碍严重程度有一定相关性,但相关检测项目显示不完全平行,在进行鉴定中应选择更为可靠的检测项目。     

Public Value Dimensions: Developing and Testing a Multi-Dimensional Classification

Further integration of the public value literature with other strands of literature within Public Administration necessitates a more specific classification of public values. This article applies a typology linked to organizational design principles, because this is useful for empirical public administration studies. Based on an existing typology of modes of governance, we develop a classification and test it empirically, using survey data from a study of the values of 501 public managers. We distinguish among seven value dimensions (the public at large, rule abidance, balancing interests, budget keeping, efficient supply, professionalism, and user focus), and we find systematic differences between organizations at different levels and with different tasks, indicating that the classification is fruitful. Our goal is to enable more precise analyses of value conflicts and improve the integration between the public value literature and other parts of the Public Administration discipline.     

Eu merger control and the compatibility test:a review of recent developments

The compatibility test contained in Article 2 of the Merger Control Regulation (MCR) is at the very heart of EU merger control, for it determines whether a concentration with a community dimension is deemed compatible or incompatible with the common market. Incompatibility can lead to prohibition of a concentration, although this is rare. The paper reviews the recent developments to the conditions of the test itself as well as the analytical methods employed to determine compatibility. Concerning the former, the new foreseeable dominance interpretation, put forward by the European Commission and made law by the Court of First Instance (CFI), is explored. This new variant of the dominance condition is important on its own right but it is also of major interest because of the explicit legal requirement placed on the Commission to assess the future likelihood of abusive behaviour by the merging parties in its prospective analysis. This is not the case with the original dominance compatibility condition. The unexpected but important clarification by the CFI of the notion of substantial part of the common market, as contained in the express wording of the compatibility test, is also commented upon. Concerning the determination of compatibility, the Commission's controversial employment in certain conglomerate concentrations of the range effects of competitive harm theory is examined, as is the need to take cognisance of merger specific efficiencies when determining if a merger increases societal welfare. The EU is making progress toward such an efficiencies assessment as part of the compatibility determination. EU merger control – and hence the compatibility test – do not exist in a vacuum. The EU has played a major role in shaping the new multilateral architecture and its goal of increasing international convergence in competition matters. This in turn has led the EU to rethink the nature of the compatibility test. For example, it has sought to evaluate the dominance condition of the compatibility test with the substantial lessening of competition (SLC) approach used by some other regulators, like the US. The paper concludes by looking at a fundamental issue that has arisen from recent CFI judgements and the GE/Honeywell merger: the competence of the Commission, or more accurately the Merger Task Force (MTF), to carry out the compatibility determination. Proposals are outlined so as to ensure that the Commission's prospective analysis in a concentration case meets the requisite legal standard. It is essential for this standard to be met if EU merger control is to remain credible. This revised version was published online in July 2006 with corrections to the Cover Date.     

踹门足迹的发现、提取与分析检验

踹门足迹是指犯罪嫌疑人用足撞击门 ,破坏锁体或门 ,使门锁分离或门板与门框分离而遗留在门面上的足迹。由于形成踹门足迹的承痕落体、作用力的大小与方向和正常步行足迹相比比较特殊 ,因此 ,它们在特征利用、分析方法和检验重点上有较大区别。

听觉诱发电位及其法医学应用价值

当一定强度的声音刺激听觉器官时,听觉系统会发生一系列的电活动,这些电活动被称为听觉诱发电位(AEP)。根据听觉诱发电位潜伏期的长短,可将其分为短、中、长潜伏期诱发电位。不同潜伏期听觉诱发电位反映听觉神经通路不同部位的脑功能活动,在法医学鉴定中可以用于听功能与听觉通路病变的客观评定。本文综述了不同听觉诱发电位产生的机制、特征及其在法医学上的应用价值。
