Evaluation of Lip Prints on Different Supports Using a Batch Image Processing Algorithm and Image Superimposition

This study aimed to develop and to assess an algorithm to facilitate lip print visualization, and to digitally analyze lip prints on different supports, by superimposition. It also aimed to classify lip prints according to sex. A batch image processing algorithm was developed, which facilitated the identification and extraction of information about lip grooves. However, it performed better for lip print images with a uniform background. Paper and glass slab allowed more correct identifications than glass and the both sides of compact disks. There was no significant difference between the type of support and the amount of matching structures located in the middle area of the lower lip. There was no evidence of association between types of lip grooves and sex. Lip groove patterns of type III and type I were the most common for both sexes. The development of systems for lip print analysis is necessary, mainly concerning digital methods.     

Innocent of the crime under investigation: suspects’ counter-interrogation strategies and statement-evidence inconsistency in strategic vs. non-strategic interviews

ABSTRACT

The study examines the counter-interrogation strategies applied by mock suspects (N?=?94), who are innocent of a mock crime under investigation but who were present at the scene, for different reasons, at around the time the crime occurred. Half were present at the crime scene to carry out a lawful act, the other half to carry out an unlawful act. Furthermore, this study examines the effect of the Strategic Use of Evidence (SUE) technique as a strategic interviewing technique (vs. a non-strategic technique), on suspects’ statement-evidence inconsistencies. Participants were randomly assigned to the two interview conditions (strategic vs. non-strategic) and were interviewed as suspects of a crime, which none of them had committed. The results show that the most commonly used counter-interrogation strategy in both groups was to be honest. However, 26.1% of the innocent suspects, performing an unlawful act, reported the strategy to be deceptive. In addition, the statements of suspects executing an unlawful act were significantly more inconsistent with the evidence in the strategic than the non-strategic interview condition. The increased statement-evidence inconsistency rates potentially put these suspects at risk of being assessed as guilty of a crime they did not commit.     

谈道路交通事故处理中讯问的技巧

对构成犯罪、依法追究刑事责任的交通事故案件,对交通肇事犯罪嫌疑人要实施讯问。道路交通事故处理中的讯问,是一项严肃的执法活动,必须严格按照法律、法规的规定进行。在道路交通事故处理中,保障讯问及时、有效地进行,保障被讯问人客观、全面地提供有关事故的真实材料,对于道路交通事故的处理工作具有十分重要的意义。文章在明确道路交通事故处理中讯问的概念与要求的基础上,深刻阐述了道路交通事故处理中讯问的技巧,目的是为道路交通事故处理的业务部门和办案民警提供帮助。     

试析侦办交通肇事案件中测谎技术之运用

交通肇事案件侦办实例说明,运用传统侦查方法侦办此类案件有一定的局限性,而运用测谎技术则有其独特的作用。测谎原理满足和平获取口供的需要,交通肇事案件中运用测谎技术成功率也较高。在运用测谎技术成功侦办交通肇事案件过程中,要善于捕捉谈话信息、巧妙收集背景资料、准确抓住心理焦点、合理搭建心理台阶、熟练把握转变时机,同时要注意保证被测人意识清醒和减少＂翻供＂的可能性。     

中药复方专利侵权诉讼中公知技术抗辩研究——兼评“天士力诉万成侵犯专利权”案

公知技术抗辩是专利侵权诉讼中被告保护自己利益的有效手段。用以抗辩的公知技术是指专利申请日之前已有的、处于公知状态的技术,但不必是可自由使用的技术。公知技术抗辩是否成立的判断应采用"二者比较创造说"。在既符合等同侵权又存在公知技术抗辩的情况下,应当优先适用公知技术抗辩。

法国庭前认罪答辩程序评析

为克服效率低下所导致的法庭堵塞,法国立法者于2004年3月9日引入了法式辩诉交易制度,即庭前认罪答辩程序。与美国及意大利的辩诉交易程序相比,法国庭前认罪答辩程序具有三大特征,即较狭窄的适用范围、较弱化的合意制度以及较完善的保障机制。从3年来的践行效果上考察,庭前认罪答辩程序虽然取得了一定的成效,但适用率并不太高,在程序规范性上仍有待加强。此外,庭前认罪答辩程序在价值认同及制度冲突层面还面临着五大挑战。     

对技防办与经济文化保卫部门职权划分的思考

安全技术防范工作是公安机关实施科技强警战略的重要内容之一 ,它关系到打、防、控一体化防范体系的形成。但是 ,在安全技术防范服务监管理工作中 ,一直存在内部职能划分不明确 ,缺乏法律强制性规定 ,导致安全防范工程系统验收质量不高 ,验收标准不一 ,验收结论缺乏权威性等一系列问题。以法律条文将技防与经文保部门的职责权限固定下来 ,理顺管理关系 ,将有助于安全防范工作的进行。     

职业安全卫生教育问题的探讨

不同手法推拿天河水穴对外感患儿的即时退热效果比较

目的 观察天河水穴在不同操作手法下的即时退热效果。方法 将94例患儿按年龄分为清天河水组、取天河水组及打马过天河组,通过测定患儿腋下体温、症状总积分和不良事件积分,评价3组临床疗效和不良反应。结果 治疗后3 h,打马过天河组患儿腋下体温及症状总积分明显低于其他两组（P<0.05）,清天河水组、取天河水组患儿腋下体温及症状总积分的差异均无统计学意义（P>0.05）;清天河水组、取天河水组不良事件积分均显著低于打马过天河组（P<0.05）。结论 3种手法均有退热效果,但打马过天河手法的即时退热效果最佳,但易造成皮损,清天河水、取天河水手法安全可靠,退热效果无差异。
