Observer determination of the make,model, and year of questioned vehicles

Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.     

Forensic Application of Analytical Mechanics in Fatal Fall From a Height

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.     

"堰塞湖"型社区治安管理模式探析 ——以北京市崔各庄东辛店村为例

基层治,则天下安。在新型城镇化纵深推进大背景下,对流动人口住处的疏解整治成为解决"大城市病"的必要手段,但实践中拆迁整治引发了"堰塞湖效应","堰塞湖效应"使得流动人口流入地社区演变成"堰塞湖"型社区。对此类社区的治安管理应革新以往防范式治安管理模式,有针对性地构建社区治安问题"审视→分析→反应→评估"的治安管理模式,根据"堰塞湖"型社区治安问题产生的原因及管理困境,形成一套从宏观到微观的逻辑严谨、运行有序的治安管理体系。具体可从树立"善治"和"共治"治安管理理念、促进流动人口社区融合和社区治安资源整合等方面入手解决"堰塞湖"型社区治安问题,以维护社区安全稳定。     

How to share and utilise expertise in a police forensic department through externalisation and mutualisation

The technique of fire investigation is a forensic domain in which expertise and analogies play a central role. To learn how fire investigators use these analogies to support their work, we conducted an ethnographic study in a Swiss forensic police department. To propose a suitable knowledge-management strategy, we also evaluated the knowledge conservation and sharing within the department. Our results highlighted that actionable knowledge is registered mainly in the investigators’ memories of a few, very experienced, individuals. Without experience with fire-incident investigations, an agent generally requires help from a more experienced colleague, who will then use his memory to find a similar case, which can contribute to the solution of the ongoing one. The research also established that knowledge is exchanged orally during on-site investigations and that knowledge receivers are generally those who are present on the scene. Using these findings, we suggest building a case library to support the externalisation and sharing of knowledge.     

劳模精神、劳动精神和工匠精神探析

党的十八大以来，在习近平总书记关于工人阶级和工会工作的系列重要讲话中，多次强调要坚 持弘扬劳模精神、劳动精神、工匠精神。认真领会劳模精神、劳动精神、工匠精神的科学内涵以及它们之间的 逻辑关系，对于实现中华民族伟大复兴的中国梦、增强文化自信和全面提升我国产业工人队伍整体素质有着重 大的理论价值和现实意义。劳模精神和劳动精神是整体和部分的关系，劳模精神和工匠精神是外力和内力的关系， 劳动精神和工匠精神是共性和个性的关系。总之，劳动精神，工匠精神，劳模精神存在逐步递进的逻辑。劳动 精神是成为人的精神，工匠精神是成为更加优秀的人的精神，劳模精神则是成为影响别人的人的精神。     

相对集中行政处罚权：立法模式与制度创新

相对集中行政处罚权实践是我国行政管理体制的创新举措,已经取得了较明显的效果。但目前囿于立法层次较低,且各地规范不一,极大地阻碍了这一新生事物的进一步成长。因此我们应在统一立法和系统全面立法的基础上,尽快制定一部法律或行政法规系统规范该制度。同时加强诸如表明身份制度、说明理由制度、阅卷制度、时效制度、格式化制度、职能分离制度、案卷排他性制度等研究,以丰富和完善该处罚权的实践。     

论我国侦查程序中法官角色的重塑

侦查程序的正当化系现代法治国家刑事诉讼文明的重要标志,而法官的应然作用对侦查程序的正当化起关键性作用。我国侦查程序中法官应然角色作用缺失,形成种种弊端,严重违背程序正义理念的要求,亟待予以重新塑造,以充分保障人权,促进我国刑事诉讼文明、民主的进程。

论新时期公安院校形象设计

公安院校形象设计是公安院校寻求广泛社会支持、提高综合竞争力、满足不同社会群体心理诉求的总体规划。设计良好、有特色的高校形象,要在确立办学理念的前提下,通过行为识别系统规范学校运行,通过视觉识别系统提升学校形象,并根据情况分别采用以传播媒介为主、以交际为主、以服务为主、以自我完善为主等不同的模式。     

信息语境下的侦查路径分析

社会分工条件下侦查主体面临着信息成本无限扩张与侦查能力相对有限之间的矛盾,社会变迁及科技发展为侦查主体加强对个体信息的渗透提供了无限可能,但这种可能性受到私权的严格限制。信息交易为侦查主体提供了一种新的低代价的信息获取渠道。
