Forensic practitioners are recommended to dark adapt their eyes prior to conducting evidential searches in the dark. The dark adaptation process remains poorly standardised across the discipline, with little quantified regarding the benefits of such preparative steps. Herein, we report the findings of a study that recruited 50 participants to assess the effectiveness of the Crime-lite Eye?, a darkness adaptation device developed to assist forensic practitioners both in the laboratory and in field. Participants were tasked with searching for the fluorescent signatures left by reaction of 1,8-diazafluoren-9-one (DFO) with amino acids, in a manner akin to the fluorogenic fingerprint treatment of porous evidence. Using an Epson Stylus Photo R265 inkjet printer, ink cartridges were filled with alanine solutions of various concentrations, allowing different motifs to be printed onto copy paper and subsequently developed using DFO. Participants searched for this ‘evidence’ both with and without dark adapted vision. On average, participants were able to locate and correctly recognise 16% more evidence once dark adapted using the Crime-lite Eye?.The increase in evidence located by participants once dark adapted suggests that crime scene officers should be dark adapting in order to visualise as much as possible. The time taken to dark adapt, 10?min on average during this study, is not excessively long, and should not significantly slow the investigation. 相似文献

Soil forensics utilizes extensive soil information to answer legal questions and test hypotheses. The main difficulty often is the determination of different variables from a small amount of soil sample collected on the suspect. We developed a sequential mineralogical and chemical analyses to assess a limited quantity of soil vestiges (0.5 g) from a suspect's vehicle (adhered to the outside rear-view mirror and to the left front fender) involved in a murder case and compared them with the surface samples found at the victim's body disposal site at the Graciosa Road, Paraná State, Brazil. All results affirm that the suspect’s vehicle could have been in contact with the edge of the Graciosa Road, approximately the place where the victim’s body was located. As a result of the soil analysis and comparison, the results support the likely contact of the suspect’s vehicle with the crime scene. 相似文献

ABSTRACTIndia is witnessing growing violence against women including horrific rapes even in major metropolitan areas that have attracted considerable media attention. Insecurity and physical threat to women is real and a major concern. Justice Verma Commission that examined the Delhi rape case has recommended several measures including changes in laws involving crimes against women, yet little has changed. In this paper we conduct a variety of qualitative and quantitative analyses using open source data to understand the nature and extent of crimes against women in India. Police records indeed suggest a growing escalation in serious crimes against women. The paper also critically examines the efforts of the police and others, particularly non-governmental groups to combat such crimes. A number of policy recommendations are made for prevention including comparative efforts in Korea where crimes against women are similarly serious. 相似文献

The purpose of this research is to extend the existing media and crime literature by discussing how minority criminal justice personnel are granted or not granted intellectual authority in fictional crime dramas by their representation as presenters of crime and non-crime fact-based statements. An analysis of 117 episodes from four fictional crime dramas appearing in the top 20 Nielson ratings from 2003 to 2010 indicate that Black characters are not given the same intellectual authority as White characters, and therefore are imbued with less power and status than their White counterparts. In some cases, Black characters are not even given intellectual authority within their respective intellectual fields. 相似文献

随着经济全球化、全球信息化的快速发展 ,有组织犯罪活动日益猖獗 ,并已成为全球关注的问题。从世界范围来看 ,不仅对什么是有组织犯罪及其范围引起了广泛的讨论 ,而且从立法和司法的角度对有组织犯罪进行了大量的对策研究 ,特别是从国际合作层面上加强刑法的一体化 ,共同打击跨国有组织犯罪越来越引起人们的关注。就我国而言 ,无论在立法上还是司法上尚存很大缺陷 ,需要进一步加以完善。为促进对这一问题的深入探讨 ,特请我国著名刑法学家、刑法学泰斗马克昌先生主持并组织了本组稿件 相似文献

2010年东南亚地区政治经济形势的发展特点可以概括为“政治上喜忧参半,经济上整体上扬,区域合作缓慢推进”。总体上讲,除泰国外,东南亚地区各国基本上都保持了政治社会的稳定;尽管挑战明显增加,但东盟共同体建设以及由东盟主导的东亚合作仍然缓慢推进;东盟国家整体实现恢复性增长,东南亚成为最具经济活力的地区之一。 相似文献

Many authors have written about issues related to privacy, legitimacy and efficiency in relation to CCTV systems in public space as a crime prevention strategy. Some have approached them separately; others have tried to come up with more comprehensive approaches. Few, however, have dealt with how such concerns have been put into practice by those who have to decide on the uptake of CCTV. This article considers some reflections on efficacy, legitimacy and privacy in relation to CCTV, as an introduction to the case of how the members of the Control Commission of Video surveillance Devices in Catalonia took these issues into consideration and interpreted the Law when deciding whether to approve a petition submitted by the City Council to install three cameras in Barcelona’s public space in 2003. It concludes by drawing some conclusions from the process, as a way to highlight the complexity of the policy process around surveillance in open, public spaces. 相似文献

法医学实践中,判断是否为“生前溺死”是法医学尸检及鉴定工作中的一个重点和难点,目前尚无能明确诊断溺死的生物学和法庭化学指标。在溺死案件的诊断中,浮游生物检验是常见的方法。尽管目前还存在一些争议,但国内法医工作者认为,器官组织中浮游生物的存在仍然是判断生前溺死的重要证据之一。本文就国内外有关浮游生物的检验方法、检验标准及... 相似文献
