对私营企业工人思想状况的调查与思考

私营企业职工,实际上是我国工人阶级中一个新的组成部分。与国有企业的工人相比,他们有自己的特点。目前,我国对私营企业的研究已经十分深入,但基本上没有包括私营企业中的工人,因此,对于私营企业工人的整体状况缺乏全面和深入的了解,所以研究私营企业工人状况已经成为一个重要的课题。     

欧洲人权法院视野下的司法令状原则

司法令状是司法审查原则的重要形式,与两大法系国家的司法令状制度相比,欧洲人权法院的审查机制和审查标准独具特色,欧洲人权法院关于强制侦查司法审查的相关判例本身已经预示着欧洲主要国家令状制度的发展方向。此外,其司法审查标准对其它国家的司法令状制度的变革和令状程序的运行实践均有深刻的借鉴意义。     

论教师在现场勘查模拟实验中的作用

现场勘查模拟实验是培养学员勘查取证能力和分析判断案情能力的最有效措施,而教师是实验教学成败与否的关键所在。要搞好现场勘查实验教学,教师首先应明确实验教学的主要目的在于培养学员的思维能力,其次要在科学的教学体系下,做好实验前的准备工作,实验过程中充分运用多种教学方法并针对不同学员的心理特点做好指导工作,实验后认真批改实验报告,从而确保现场勘查实验教学的质量。     

卧底侦查人员违法犯罪的免责问题探讨

卧底侦查在对付恐怖主义、有组织犯罪、毒品犯罪等方面发挥着至关重要的作用。卧底侦查人员违法犯罪存在免责的可行性。法律应当对卧底侦查人员违法犯罪界限作出规定,对卧底侦查人员违法犯罪的责任问题应明确,从而进一步保护卧底侦查人员的权利。     

高层住宅楼攀爬式入屋盗窃案件的对策

高层住宅楼入屋盗窃案件近年来逐年增多,特别是高层住宅楼攀爬式入屋盗窃案件显得尤为突出。高层住宅楼攀爬式入屋盗窃案件作案人作案手段、方式和特点都具有特殊性,应据此采取相应的侦查与防范对策。     

论毒品犯罪侦查中的控制下交付手段

控制下交付是目前国际社会普遍认同的,在打击跨国、跨地区毒品犯罪中发挥重要作用的侦查手段,具有隐蔽性、合法性等特点。近几年我国侦查机关运用该手段取得了较好的成效。但运用控制下交付必须遵循一定的实施原则,并注意与此相关的法律问题。     

当前侦查合成战中的问题与对策思考

作为打击犯罪的一种新型工作模式,侦查合成战不仅仅是对各警种、部门乃至其他社会部门人力、物力的简单相加,还应当包括观念提升、队伍建设、机制保障、绩效考评等更高维度的内容。当前侦查合成战在思想认识、工作机制、工作方式等方面存在着一些问题,制约了侦查工作的开展。围绕此类问题开展破题。将有利于提升侦查工作效能,提升公安机关打击犯罪的能力。     

The Influence of New Technologies on the Visual Attention of CSIs Performing a Crime Scene Investigation

Currently, a series of promising new tools are under development that will enable crime scene investigators (CSIs) to analyze traces in situ during the crime scene investigation or enable them to detect blood and provide information on the age of blood. An experiment is conducted with thirty CSIs investigating a violent robbery at a mock crime scene to study the influence of such technologies on the perception and interpretation of traces during the first phase of the investigation. Results show that in their search for traces, CSIs are not directed by the availability of technologies, which is a reassuring finding. Qualitative findings suggest that CSIs are generally more focused on analyzing perpetrator traces than on reconstructing the event. A focus on perpetrator traces might become a risk when other crime‐related traces are overlooked, and when analyzed traces are in fact not crime‐related and in consequence lead to the identification of innocent suspects.     

The making of an expert detective: the role of experience in English and Norwegian police officers’ investigative decision-making

Biased decision-making in criminal investigations can impede or arrest the progress of justice. Previous research has not systematically addressed the effects of professional experience on the quality of detectives’ decision-making. Using a quasi-experimental design, this study compared the quality of investigative decisions made by experienced detectives and novice police officers in two countries with markedly different models for the development of investigative expertise (England and Norway). Participants (N?=?124) were presented with two semi-fictitious cases and were asked to report all relevant investigative hypotheses and necessary investigative actions in each case. The quality of participants’ responses was gauged against a gold standard established by a panel of senior homicide experts. In the English sample, experienced detectives vastly outperformed novice police officers in the number of reported gold-standard investigative hypotheses and actions. In the Norwegian sample, however, experienced detectives did not perform any better than novices. We argue that English (vs. Norwegian) detectives may benefit more from professional experience due to their Professionalising Investigation Programme and a nationwide accreditation program, requiring them to engage in extensive standardized training, systematic evaluation and synchronized development. In contrast, Norway lacks such requirements. Methodological limitations and implications for police training and accreditation policies are discussed.
