The use of human skin in the fabrication of a bite mark template: two case reports

Comparison of a suspected biter's dental arches with the patterned injury of a bite mark is especially difficult when the bite occurs in an anatomic location with a small radius of curvature or with complex or compound curves. The authors present two case reports in which human skin was used as a template for the reproduction of a bite. In one case the victim's skin was used; in the other, the skin of a anatomically similar person was used. The use of inked dental casts, photography, and transparent overlays significantly reduced the errors common to analysis of bite marks in these highly curved areas.     

Identification of the driver in two-rider motorcycle accidents. Inguinal contusion-laceration as an indication of the driver

In motorcycle accidents involving two riders, medicolegal identification of the driver is necessary when one or both riders die. It is particularly important in the latter case, because the survivor almost always insists that he or she was not driving. One characteristic injury that distinguishes the driver from the passenger is inguinal contusion-laceration (accompanied internally by pelvic fracture). This injury, caused by collision of the pelvis with the fuel tank, identifies the driver.

番鸭花肝病病原的研究

从广西患花肝病的雏番鸭肝、脾分离到 3株病毒 ,定名为NM1、NM2 、NM3。这 3株病毒能在番鸭胚和番鸭胚成纤维细胞上增殖 ,并产生细胞病变。人工感染 1日龄番鸭致死率达 10 0 % ,但对鸡、康贝尔鸭和鹅不致病。分离毒对氯仿不敏感 ,耐热、耐酸 ,不被DNA抑制物所抑制。分离毒的细胞培养物经超薄切片 ,磷钨酸负染 ,在电镜下观察到大量球形、实心 (少量空心 )的病毒粒子 ,其直径 6 6～ 70nm ,无囊膜 ,属无囊膜的RNA病毒     

Is full better than half? Examining the longitudinal effects of full‐day kindergarten attendance

Kindergarten policy varies widely both across and within states. Over the past decade, a number of states have instituted a full‐day kindergarten requirement and others are considering it as a way to increase educational achievement. Many parents also support full‐day kindergarten as a source of child care. This paper uses the Early Child Longitudinal Study–Kindergarten Class of 1998–1999 to evaluate the efficacy of this policy. In ordinary least squares, probit, county fixed effects, and instrumental variables models, we find that there are initial benefits for students and the mothers of students who attend full‐day kindergarten, but that these differences largely evaporate by third grade. Contrary to claims by some advocates, attending full‐day kindergarten is found to have no additional benefit for students in families with income below the poverty threshold. © 2006 by the Association for Public Policy Analysis and Management     

毛泽东的科学立宪思想与中国宪政发展

在领导和亲自参加制定1954年宪法的过程中,毛泽东以科学的态度对立宪权的归属、立宪权的行使、立宪程序的遵循、宪法内容的正当性、宪法外在结构的合理性等立宪问题都进行了深入探索。其科学立宪思想为我国的宪政实践积累了宝贵的精神财富,对当前中国共产党领导人民如何以科学精神完善宪法,依宪执政,进而依宪治国,都有着重要的理论和实践意义。     

社区居民政治参与"路径依赖"现象的成因及消解对策

社区居民政治参与的路径依赖表现在制度锁定、被动参与和参与成本过高。强国家、弱社会格局,单位制到社区制的转轨尚未完成,社区居委会功能错位和社区居民主体意识不高构成其根源。破除路径依赖的办法是:加快社会结构转型和政府职能转变,积极培育社区居民的主体意识,培育民间组织。     

公安院校刑事技术实验课分层次教学法研究

刑事技术是一门专业性和实践性非常强的综合应用型技术。刑事技术本科专业教学如何更好地适应公安基层实践对高层次专门人才的需求,培养出一大批善于学习、实践能力强并具有一定创新精神的应用人才是当前形势下公安院校深化教学改革,提高教学质量,全面推进大学生素质教育的研究热点之一。笔者从公安基层刑事技术实践对刑事技术专业人才的需求特征及技术员职业岗位和公安刑事技术实验教学改革要求出发,就实施以培养学生的动手操作能力、综合应用能力和实践创新能力为目标的分层次教学法的人才培养方案,处理好强化基本功的训练、突出综合应用能力和实践能力的培养、支持引导激励学生开展探索性的实践活动等三个层次关系及切实保障刑事技术实验课分层次教学法实施进行研讨。
