Addressing identity crime in crime management information systems: Definitions,classification, and empirics

Identity fraud as a term and concept in its formative stages was often presumed to be identity theft and visa versa. However, identity theft is caused by the identities (or tokens) of individuals or organisations being stolen is an enabling precursor to identity fraud. The boundaries of identity fraud and identity theft are now better defined. The absence of specific identity crime legislation could be a cause of perpetrators not classified as breaching identity crimes but under other specific entrenched law such as benefit fraud, or credit card fraud. This metrics overlap can cause bias in crime management information systems. This study uses a multi-method approach where data was collected in both a quantitative and qualitative manner. These approaches are used as a lens for defining different classes of online identity crimes in a crime management (IS) security context. In doing so, we contribute to a deeper understanding of identity crime by specifically examining its hierarchical classes and definitions; to aid clearer structure in crime management IS. We seek to answer the questions: should current law around identity fraud continue to be reinforced and measures introduced to prevent identity crime; should laws be amended; or should new identity crime laws be constructed? We conclude and recommend a solution incorporating elements of all three.     

家兔死后离体血液ATP含量变化与放置时间的关系

目的探讨恒温(25℃)条件下家兔死后离体血液ATP含量变化与放置时间的关系。方法健康家兔8只,空气栓塞处死后即刻取右心室血液,置于25℃恒温水浴槽中,每4h应用ATP荧光快速检测仪检测血液ATP含量,所得数据应用SPSS17.0统计学软件进行方差检验及回归分析。结果恒温(25℃)环境下,家兔死后离体血液的ATP含量,在8h内从死后即刻的2.46×10-12mol/L升至3.09×10-12mol/L,8h之后则随PMI的延长而下降,直至56h,56～72h ATP含量在0.13×10-12mol/L时趋于稳定。以Log[ATP]为因变量(y),离体放置时间为自变量(x),对死后0～56h的数据进行回归曲线分析,建立了3个推断离体时间方程,即y=-0.019x-11.359(R2=0.763)、y=0.001x2+0.016x-11.666(R2=0.962)和y=-1.281×10-5x3-0.007x-11.576(R2=0.980),其中三元回归方程的系数为0.980,曲线拟合度最好。结论家兔离体血液ATP含量变化与放置时间呈现一定的规律性,有望应用于死亡时间推断。     

Structure elucidation of dyes that are formed in the colorimetric detection of the improvised explosive urea nitrate

Urea nitrate (uronium nitrate, UN) is a powerful, improvised explosive that can be easily made from urea and nitric acid. It is considered the most frequently used, illegal explosive in the Israeli arena, which is responsible for the loss of more than a hundred lives in terrorist incidents. Urea nitrate is a colorless, crystalline substance that looks very much like sugar. A sensitive color test for UN was developed recently. It is based on the formation of a red dye in the reaction between p-dimethylaminocinnamaldehyde and UN under neutral conditions. A similar reaction with p-dimethylaminobezaldehyde produces a yellow dye. The two dyes have been synthesized, and their structures determined by X-ray crystallography. Both dyes are protonated Schiff bases, prevailing in the crystal in a quinoid form. They are identical to the compounds, which are obtained in the colorimetric detection of urea with the same reagents, under strong acidic conditions, whose structures have been postulated in the literature, but never fully proved experimentally.

侦查讯问中谎言的成因与识别

谎言在侦查讯问中主要表现为虚假供述,可分为无犯罪行为者的虚假供述和有犯罪行为者的虚假供述。这两种不同性质的虚假供述的成因及其伴随表征的分析判断,对谎言识别具有重要的作用与意义。     

表面增强拉曼光谱快速检测食品基质中毒物

目的建立常见食品基质中氰化物等五种毒物的拉曼光谱快速分析方法。方法采用水、乙腈及乙酸乙酯作为提取剂对饮用水、苹果以及烤鸭三种常见食品基质中氰化物、百草枯、毒死蜱、甲拌磷以及敌鼠钠五种毒物进行提取,并使用表面增强拉曼光谱法检测。结果实验表明,每种毒物均有其独特的拉曼信号,这些特征信号可作为其定性的判别依据,氰化物在饮用水、苹果以及烤鸭这三种基质中的检出限均不大于1μg/mL(g);百草枯的检出限在0.05~0.1μg/mL(g)之间;毒死蜱、甲拌磷的检出限在0.05~1μg/mL(g)之间;敌鼠钠检出限在0.1~1μg/mL(g)之间,均满足现场检测需求。结论该方法操作简单且分析速度快,为毒物的快速筛查提供了较好的解决方案。     

论侦查效果:结构、范畴与规律

侦查效果虽然是常见的概念,却有着复杂的认识结构,包括认识主体、认识客体、认识关系。侦查效果是一种有层次的区分主体的地方化认识结果。认识论意义上的复杂性导致了侦查效果范畴的复杂性。由此衍生出了侦查效果的两个规律,即侦查主体需求和环境因素决定侦查效果的选择;侦查能力和社会治安情势决定侦查效果的实现程度。     

打击传销犯罪案件侦查新模式

创新打击传销犯罪侦查模式,要充分利用信息化侦查手段,拓展传销犯罪的线索来源。通过慎密侦查,精心经营案件线索,初步查明犯罪事实,准确定性;充分做好准备工作,制定处置预案;组织力量,明确分工,抓捕犯罪嫌疑人,取缔传销窝点;跟踪资金流向,准确认定传销犯罪的组织者与领导者;彻底摧毁传销组织、杜绝传销行为,标本兼治,实现法律效果与社会效果的统一。     

脑认知神经测谎技术及应用性述评

本文主要回顾了当前主要的几种脑认知成像技术以及其在测谎中的尝试,介绍了这些成像技术的研究成果,并对这些测谎技术的应用性及所面临的问题等做出讨论。     

论我国反恐特别侦查程序的制度构建

当前，随着恐怖犯罪行为秘密化、组织化、技术化趋势的不断发展，愈发凸显出普通刑事程序规则在预防和打击恐怖犯罪方面的缺陷和不足，并对具体的如调查取证、人身羁押、技侦等特殊侦查措施的应用造成了很大困难。为此，本文建议我国应在反思本国实践教训和借鉴外国经验的基础上，通过不断的理念突破和制度创新，构建符合我国反恐实践的特别侦查程序机制。
