多发性食品犯罪案件检测鉴定问题研究——以福建省食品犯罪案件侦查为视角

当前,在公安机关办理食品犯罪案件中,检测鉴定问题已成为困扰案件侦办的瓶颈。对福建省食品犯罪案件总体情况和食品检测鉴定现状的调研显示,从食品检测鉴定主体到检测鉴定标准再到检测鉴定结果运用的整个链路上存在着检测能力不足、周期过长、结果准确率低等问题。解决上述问题,需要从检测鉴定体系、司法协作、保障机制、办案指引等方面构建多维合作的应对机制。     

基于紫外可见反射光谱法对染色头发的初步研究

紫外可见反射光谱法是一种快速无损检验的方法,本文从采样量、样品的固定等方面对染色头发进行紫外可见光谱检验方法进行了初步探索,使用紫外可见光谱仪的积分球附件可以对不同染发剂染色头发进行大致的分类鉴别。     

A large study evaluation of evidence types containing offender fingerprints from recorded crimes in North Macedonia from 2005 to 2015

The Forensic Institute of the Republic of North Macedonia data set of 1,982 offender fingerprint identifications contributing to a conviction for crimes against property, was evaluated and analysed using contingency table statistical analysis techniques, chi-square test, fisher’s exact test and post hoc analysis. The data set was based on the forensic and court information available from 2005 to 2015 and pertained to the location, property type and evidence type. Interpretation of the data identified glass components, doors, windows, points of entry, cardboard and other packaging to be the most likely areas for locating offender fingerprints in non-residential and residential properties. In vehicle-based crimes, the front area (both left- and right-hand side) was the most likely to yield offender fingerprints.This study reinforced the types of evidential items at property based crime scenes yielding offender fingerprints. In addition, the study seeks to provide recommendations for future data collection to enhance the data analysis and interpretation.     

对计算机打印变更伪造文件的检验

随着计算机应用普及率的不断提高及社会作用的逐渐增大,计算机处理文字的优越性也给不法分子刻意变更伪造文件提供了机会。文章提出了计算机打印追加变更伪造文件内容的传统检验方法,从计算机打印的呈现特点入手,对传统机械比对法进行论述,并用案例对此问题加以论证。根据案例分析和实验结果证明传统人为机械比对法是检验的有效途径之一,这种检验方法不但对促进文检工作有一定现实意义,而且对预防犯罪也有一定的积极意义。     

我国心理测试结论的证据属性与定位

国外关于心理测试（测谎）结论的证据资格已得到确认,目前我国对心理测试机构、测试人员、测试对象、测试仪器、测试方法、测试环境、测试过程和测试结论等都做了程序性规定,标志着心理测试技术在国内正式进入了刑事科学技术专业序列,是对国内心理测试技术的一个全新定位。测试结论在证据的＂有限采用规则＂和补强证据的框架下,鉴于我国心理测试结论在证据价值方面存在诸多争议,＂有限采用规则＂对我国测试结论的规范使用有很好的借鉴意义。把测谎结论定位于补强证据可能会比较实用,可以辅助验证其他证据,尤其是验证证词的真伪,在我国司法领域具有广泛的应用价值。     

变截面桩竖向承载性状的模型实验研究

利用自行研发的试验装置进行了半桩模型试验研究,分析了变截面桩的荷载-沉降曲线、桩身轴力分布情况、桩身侧摩阻力分布情况,并与常规等截面桩进行比较.模型试验结果表明：变截面桩较等截面桩更有利于减小桩体的沉降量,但从单桩沉降变形的角度看,变截面桩存在最佳变径比.当变径比超过这一最佳值时,变径比越大,桩的沉降变形也就越大,甚至超过等截面桩的沉降量.桩顶荷载首先并主要通过变截面处以上桩身传递,该部分桩身段是主要承载部位.由于变截面处下部土体对桩的支撑作用,变截面桩的桩身轴力在变截面处附近有较大程度的衰减.变截面桩的桩身侧摩阻力比常规等截面桩发挥更加充分.     

关于ERP与CPS测谎技术的心理测量学差异的研究

事件相关电位心理测试技术与传统的多道心理生理测试技术相比,遵循着不同的基本原理和机制,由此带来二者在心理测量学上的差异。文章拟从心理测量学的行为样本、标准化、难度客观性测量以及信度、效度五个方面来分析两种测试方式的差异。     

沥青混合料劈裂试验的扩展有限元法数值模拟

扩展有限元法是近年来迅速发展的一种新型数值方法,为了深入分析沥青混合料在荷载作用下的破损机理,将该方法引入到沥青路面计算,以沥青混合料劈裂试验为例,利用ABAQUS有限元软件,采用双线性内聚力模型模拟劈裂试验裂纹扩展过程,并将数值模拟结果和试验结果进行了比较分析.结果表明数值计算结果和试验结果吻合很好,扩展有限元法应用于沥青路面结构计算分析是可行的,可供工程技术人员参考.     

The Bechdel in India: gendered depictions in contemporary Hindi cinema

The Bechdel test is a popular measure used to examine the adequacy of representation of women in movies, and other media. Although often applied to Hollywood movies, the test has rarely, if ever, been used to assess Hindi cinema. This paper adopts, adapts, and extends the original Bechdel test to scrutinise stereotypical, non-stereotypical, and typical dialogic content of same-sex conversations in three genres of Hindi cinema – top-grossing blockbuster films, women-centric movies, and parallel cinema. Using a qualitative approach to code dialogues, and quantifying subsequent frequencies, the current work highlights the underrepresentation and misrepresentation of female characters in contemporary Hindi cinema. The time taken for men to speak to men and women to speak to women was also quantified. While women-centric and parallel films depict a more balanced portrayal of male and female characters, top-grossing films are heavily lopsided, with some being devoid of a second female lead, and hence of female-to-female dialogues. Male characters spoke of more varied areas, both stereotypical and non-stereotypical, than women particularly in top-grossing content. The implications of such depictions in cinema, and their subsequent effect on perceptions of men and women in society, is discussed.
