Two-dimensional metric comparisons between dynamic bare footprints and insole foot impressions-forensic implications

Footwear may be found at crime scenes as physical evidence. Such footwear often has impression features of the wearer’s foot on the insole of the shoe. Scientific research and literature have established that footprints are distinct. This study compares two-dimensional measurements on bare footprints to foot impressions on insoles to determine if significant differences or similarities exist. Dynamic footprints were collected from 51 donors using the Identicator® Inkless Shoe Print Model LE 25P system. Seven foot length and width measurements were taken based on the Reel linear measurement method. Footprint measurements between bare footprints and foot impressions on the insoles were compared. Only two differences (p > 0.05) were observed between the various bare footprint and insole foot impression measurements on the right and left side for most of the measurements, CALC (p < 0.001) and A1 (p = 0.04). Bare footprint and insole A5 measurements on the left side were also significantly different (p = 0.015). The results of the study have implications in the forensic analysis of foot impression evidence on insoles in footwear in assisting with identifying the wearer of said footwear. Situations may arise in the forensic context when comparing the foot impression on the insole of footwear to a suspect’s bare footprint or a footprint from post-mortem remains. This study contributes to the scant literature available on the topic and to understanding the similarities and differences observed in the various linear measurements that may be utilized in the comparison process of footprint impressions on shoe insoles to bare footprints.     

防范化解政治领域重大风险探析

A Qualitative Assessment of Stress Perceptions Among Members of a Homicide Unit

Existing research on stress among police assumes the presence of uniform stressors across job roles and borrows upon generic stress instruments to tap stress types and levels. The present study draws upon interviews with 26 members of a metropolitan homicide unit to provide an inductive vantage point on stress perceptions within a specialized area of policing. We provide evidence that the occupational and organizational forms of stress detailed by these officers are shaped largely by the unique nature of homicide work. Among the unique task-related stressors observed include the complexities of homicide crime scenes, time pressures, cases assignment factors, paperwork demands, and long-term ownership over individual case files. A series of structural issues from both within and outside the police agency are identified as organizational stressors unique to homicide work. We conclude with a proposed theory of homicide investigator stress and implications for future research.

公安机关现场勘验信息系统存在的问题及对策

全国公安机关现场勘验信息系统是公安机关"三基工程"的重点建设项目之一,对增强勘查能力、优化侦查模式、提升破案效益、提高科学打击犯罪水平等具有重要作用。但是,在日常使用过程中,系统的功能未得到充分发挥。     

A study of user data integrity during acquisition of Android devices

At the time of this writing, Android devices are widely used, and many studies considering methods of forensic acquisition of data from Android devices have been conducted. Similarly, a diverse collection of smartphone forensic tools has also been introduced. However, studies conducted thus far do not normally guarantee data integrity required for digital forensic investigations. Therefore, this work uses a previously proposed method of Android device acquisition utilizing ‘Recovery Mode’. This work evaluates Android Recovery Mode variables that potentially compromise data integrity at the time of data acquisition. Based on the conducted analysis, an Android data acquisition tool that ensures the integrity of acquired data is developed, which is demonstrated in a case study to test tool's ability to preserve data integrity.     

新建本科院校大学章程建设的思考

由于社会历史原因，我国高等教育发展还很不平衡，尤其是新建本科院校在大学章程制定和执行方面存在不少制约因素。但是大学章程建设是加快建立有中国特色现代大学制度、提高高等教育育人效能的基础工程，作为新建本科院校必须统一思想，凝聚共识；广泛宣传，充分论证；切实把握《高等学校章程制定暂行办法》基本要素，以完善学校法人治理结构为重点，与依法治校紧密结合，在大学章程建设方面大胆探索，勇于实践。     

诱惑侦查之立法困惑——新刑诉法第151条的相关问题讨论

为了惩治犯罪的需要,现实中侦查机关经常采用有关人员隐蔽身份搜集信息、获取证据的手段,但是刑诉法中一直未见其相关规定。实践中的频繁运用与法律上的空白规定不符合目前侦查工作的需要。因此,新修订的刑诉法在"侦查"一章"技术侦查措施"一节作出了相关规定,对此种侦查措施进行法律调整。然而,该规定仍然存在一些不明确的地方,比如其在章节中的位置问题、但书的内涵等。     

网络诽谤犯罪立案管辖之困境与价值抉择

本文对网络诽谤犯罪案件载体与形式进行了重新评估,并解释了刑法扩张的合理性,试图从诽谤犯罪规制的价值选择出发,考察域外法制,平衡社会公益与公民权利,平衡言论自由与公民人格尊严,提出修正现行法律规范的建议,或加强公权力救济、强化现行法律框架下的侦查权合理运行。     

社会转型中法官法治思维养成困境及路径探究

社会转型中,作为法律职业者之一的法官群体,如何去考量法治思维的因素倍加值得关注与重视,由于受限于现实司法体制、根植于传统司法文化、纠结于多种思维影响之间,法官法治思维的养成仍存诸多困境。立足于对所在区域法院展开一定实证调研和引入相关心理学、教育学知识的基础上,探索建构我国法官法治思维养成的路径既有强烈的现实需求,又有深远的指引意义。完善制度建设、强化思维训练、改进教育培训乃是三种路径的基本设想。
