ABO位点限制性扩增片段长度多态性的研究

建立了PCR扩增、限制性酶切、8％（T）、5％（C）聚丙烯酸胺凝胶垂直电泳和银染检测ABO位点的限制性片段长度多态性的方法体系。应用Amp-RFLP技术对185名中国人（哈尔滨）ABO位点的基因频率和基因型分布进行了调查和统计分析。ABO位点特异片段长度为140～200bp，基因频率为0．2000～0．5568。6种基因型频率为0．973～0．3135，杂合度0．5838，Dp值0．7146。经H－W平衡吻合度检测，完全符合群体遗传多态分布。通过对11个家庭33名相关个体的分析，证明完全符合孟德尔遗传定律。ABO基因型检验适用于法庭科学的个体识别和亲权鉴定。     

Response to Lindsay,Mansour, Beaudry,Leach and Bertrand's Sequential lineup presentation: Patterns and policy

This paper is a response to the earlier paper by Lindsay, Mansour, Beaudry, Leach and Bertrand (2009). We argue that eyewitness research is an important public good and that high‐quality in research and policy formulations offered to the public interest is required to maintain our standing of trust. We argue that even though sequential lineups have been successfully codified in some jurisdictions as the exclusive eyewitness identification procedure, the claim of sequential superiority is built upon errors in the research process and that the evidence of reduced false identification with sequential lineups is completely offset by reductions in correct identifications. We reject the idea that the loss of correct identifications can be dismissed as guessing on the basis that this is speculative and that there is no published empirical support for the idea. We reject the idea that false identifications are necessarily more valuable for society to reduce than are correct identifications to achieve. Improvements in eyewitness identification are important, and interesting lines of investigation are available. It is questionable whether the sequential lineup is important among them.     

ABC法检测血小板颗粒膜蛋白鉴别生前伤与死后伤

甲抗人血小板α-颗粒膜蛋白140（GMP－140）单克隆抗体，ABC免疫组化方法鉴别生前伤与死后伤．生前皮肤切创和刺创标本创缘上见条状褐色反应带，死后皮肤切创标本创线上未见上述反应带。该法可用于检测短时期发生的生前伤与死后伤。     

紫外-可见光谱法研究蓝色圆珠笔色痕自然老化规律

目的论述自然老化下蓝色圆珠笔色痕中染料成分的变化规律。方法利用UV-VIS光谱对圆珠笔文字色痕中染料成分相对于铜酞菁的变化进行实验。结果得到染料与铜酞菁吸光度之比随老化时间变化的数据和曲线。结论利用UV-Vis光谱研究文件制成时间是可行的,为书写时间的鉴定拓展了思路。     

WOMEN'S PARTICIPATION IN CHINESE TRANSNATIONAL HUMAN SMUGGLING: A GENDERED MARKET PERSPECTIVE*

Despite extensive sociological research on gender and organizations, criminologists have paid insufficient attention to how organizational context and market demands may shape the extent and nature of women's participation in illicit enterprises. This study uses an organizational framework to examine the case of Chinese human smuggling to the United States. Drawing from interviews with 129 human smugglers, we propose a gendered market perspective for understanding the place of women in the human smuggling enterprise. We argue that the limited place of violence and turf as organizing features of human smuggling, the importance of interpersonal networks in defining and facilitating smuggling operations, gender ideologies about work and caregiving, and the impact of safety as an overriding concern for clients combine to create a more meaningful niche for women in human smuggling operations than is found in other criminal endeavors. Our research suggests that organizational and market contexts are significant explanations for gender stratification in illicit enterprises.     

自动固相萃取法(SPE)提取常见安眠镇静药

目的为筛选检验血、尿中未知安眠镇静药和三环抗忧郁药建立一种简便、快速的自动固相萃取方法。方法采用美国Zymark公司的自动固相萃取仪和Waters公司的OasisHLB固相萃取柱,同步提取血、尿中的25种常见安眠镇静药(包括巴比妥类、苯二氮卓类、吩噻嗪类药物等)和三环抗忧郁药。结果尿中药物提取率大部分达到80%以上;血中药物提取率在75%以上。结论该方法具有提取过程自动化,操作简便快捷,提取回收率高、重现性好、提取物干净等特点,可用于实际案件中血、尿中未知安眠镇静药和三环抗忧郁药的提取检验。     

浙江畲族人群9个STR基因座的遗传多态性

目的调查浙江畲族人群STR基因座的遗传多态性,为群体遗传学和法医学个人识别、亲子鉴定提供基础数据。方法采用AmpFlSTRProfilerPlus试剂盒(ABI公司),ABI310基因自动分析仪对浙江畲族120名无关个体血样的D3S1358、VWA、FGA、D8S1179、D21S11、D18S51、D5S818、D13S317和D7S820等9个STR基因座进行等位基因频率和基因型频率调查。结果获得浙江畲族人群9个STR基因座的基因频率分布资料,所有基因座基因型频率分布均符合Hardy—Weinberg平衡,计算得杂合度(H)0.655～0.960,个人识别率(DP)0.878～0.960,非父排除率(PE)0.363～0.677,多态信息总量(PIC)0.68～0.86。结论该9个STR基因座在浙江畲族人群中呈高度多态性,在法医学及人类遗传学研究中具有重要意义。
