论视频监控的犯罪预防功能及犯罪侦查价值

各国的犯罪预防理论发展至今,已经形成了比较完善的犯罪预防体系,主要包括司法预防、社会预防和情景预防三种模式。在我国的犯罪预防体系中,向来重视司法预防和社会预防,而对情景预防关注不够,情景预防措施尚不完善。作为一种对犯罪的干预,视频监控是一种对情境犯罪的干预,研究发掘其在犯罪预防中的作用对完善犯罪预防体系具有重要意义。同时,视频监控系统在犯罪侦查方面也具有重要作用。     

视频侦查规范化研究

视频侦查是指侦查机关根据案件的需要,通过视频监控资料的调取、观看、分析和应用四个环节,实现对犯罪的动态分析和综合判断,以发现和确定犯罪嫌疑人、寻找破案线索,为案件侦查提供方向的一种侦查措施。视频侦查已成为继刑事技术、行动技术、网侦技术之后侦查破案的技术支撑和新的破案增长点,成为强化社会治安控制的有效手段,对提高侦查机关打击犯罪的效能具有重大意义。     

视频图像侦查中涉案目标消失的原因分析与应对

在视频图像侦查过程中,经常会发生视频追踪对象在某个特定区域的视频监控图像中＂消失＂的现象。它可能是由于存在监控盲区造成的,也有可能是由于犯罪嫌疑人的反侦查行为,或者侦查员在视频监控资料收集、处理、查看过程中存在问题造成的。因此,我们可以通过合理布局,减少监控盲区,广泛收集和处理视频监控资料,深入查看和分析视频消失区域,多种侦查手段并用等途径来加以应对。     

Recovery of Environmental Human DNA by Insects*,†

Abstract: We tested the hypotheses that foraging insects can acquire human DNA from the environment and that insect‐delivered human DNA is of sufficient quantity and quality to permit standard forensic analyses. Houseflies, German cockroaches, and camel crickets were exposed to dusty surfaces and then assayed for human mitochondrial and nuclear loci by conventional and qPCR, and multiplex STR amplification. Over two experiments, 100% of insect groups and 94% of dust controls tested positive for human DNA. Of 177 individuals, 33–67% tested positive and 13 yielded quantifiable human DNA (mean = 0.022 ± 0.006 ng; mean dust control = 2.448 ± 0.960 ng); four had at least one positive allele call for one or more locus; eight others showed multiple peaks at some loci. Results imply that application to routine forensic casework is limited given current detection methodology yet demonstrate the potential use of insects as environmental samplers for human DNA.     

论废除监视居住的理由

在社会转型时期,由于犯罪现象本身呈现出与常态社会的极大不同,以保障人权和追诉犯罪为目的的刑事强制措施也得因之变化。监视居住是我国刑事诉讼法规定的一种强制措施,但现如今,随着其制度生存的社会根基被剥离,适用条件违反了比例原则,适用空间极其微小,以及无法破除的执行困境等废除理由的凸显和强化,它必将日渐式微并最终被废除。     

Exploitation of the Ultraviolet Properties and Machine Cut Edges of Paper to Associate and Sequence Sheets in a Ream

Previously unreported line patterns visible under ultraviolet light were observed on a proportion of plain white A4 printer/copier paper from different manufacturers. These Ultraviolet Line Patterns (UVLPs) usually appear as stripes down the vertical length of the paper. Typically, the UVLPs were found to “repeat” through the ream in a predictable way, while also changing. It is postulated that the repeating nature of the UVLPs is a result of the way that paper is manufactured. This leads to the ability to sequence the sheets compared to their original source paper. Even in the absence of UVLPs, it is possible to use our observation of the manufacturing process to anticipate the order of several sheets of paper and conclusively associate them, in some cases, by physically fitting their machine cut edges and crossing paper fibers. Such a novel approach to examining questioned documents would be highly useful in forensic casework.     

Confidence‐building measures at sea: The challenges ahead in Southeast Asia

Southeast Asia faces a range of challenges in adopting maritime confidence‐ and trust‐building measures in the very promising atmosphere of political endorsement that exists after the ASEAN Regional Forum, with possible changes to the strategic balance caused by maritime rearmament within the region. This paper briefly analyses the roles or activities of maritime forces in the region on the basis of their sensitivity to scrutiny: the hard or contentious kinds of activities, usually warlike, that navies will only practise together in an environment of considerable trust, and the soft, usually non‐warlike activities, that they could undertake cooperatively with fewer security concerns. From this list of shared roles two lists of possible CBMs are derived, the easy (or likely‐to‐succeed) and the hard (or less‐likely), based on the level of sensitivity of the activities to be undertaken cooperatively.     

Monitoring School Violence

Abstract

National monitoring of school violence is essential for needs assessments, policymaking, and evaluation at the national level. As informative and important as national monitoring is, the data generated at the national level is often not useful at the district or school site levels. There is therefore a need for a feasible method of monitoring school violence on the district and school level; furthermore, we need to find ways to effectively apply national-level information to schools and school districts. over time should be the foundation for the design, implementation, and evaluation of interventions in this area. In this article, we propose an expanded concept of monitoring that links comparable data on school violence at the grade, school site, district, and national levels. The paper presents our conceptual framework and methodology and illustrates its implementation in a district in Israel. We present examples of reports generated to monitor school violence for the district as a whole and for each of the school sites. Finally, we conclude that this is a feasible and useful model that social services could adopt to monitor practice in many other areas.
