论禁止双重危险原则中的同一性问题——以美国法律实践为视角

禁止双重危险原则是刑事诉讼中保障被告人合法权益的重要制度设计。美国法院在执行这一原则时先后使用了同一要素标准、同一行为标准及同一证据标准。之所以出现如此反复,是美国司法实践在犯罪事实及刑罚对象认识方面不断深化的结果。我国刑事司法应当借鉴关国在禁止双重危险原则之同一性问题上的司法经验,合理优化吸收犯与牵连犯理论,落实罪刑相适应原则。

Hair as a specimen to document tetramethylene disulfotetramine exposure

Tetramethylene disulfotetramine (tetramine) is a rodenticide that has been banned for many years in China. Since 2005, inhabitants of a village in the Henan Province have been suffering from grand mal seizures. To investigate the possibility of tetramine as the cause, we developed a method to determine tetramine in human hair. Sample preparation involved external decontamination, frozen pulverization, and ultrasonication in 2 mL ethyl acetate in the presence of cocaine-d3 as an internal standard. The method exhibited good linearity; calibration curve was linear over a range of 0.1-20 ng/mg hair. The limit of detection for the assay was 0.05 ng/mg hair. Except for one subject (No. 4), all head and pubic hair samples were positive for tetramine. The concentrations of tetramine in pubic hair were significantly higher than those in the same subjects' head hair samples. Because of a long retention in body, segmental head hair analysis cannot provide an accurate exposure history of tetramine in the body.     

论如何运用行政法之诚信原则改善政府信用现状

政府作为一个国家的权力机构和管理机构,其运行须遵从正式的法律、规范,且有一定的制度作为保障。行政法对行政权力的控制与平衡是改善政府信用的重要途径,而其中的诚信原则更突出了政府法治讲求诚信的重要意义。从行政法的角度探析如何运用行政法中的诚信原则来改善政府与民众之间的信任关系,提高政府信用度具有现实意义。     

Validation studies of the ParaDNA® Intelligence System with artificial evidence items

Short tandem repeat (STR) profiling is one of the mostly used systems for forensic applications. In certain circumstances, STR profiling is time-consuming and costly, which potentially leads to delays in criminal investigations. LGC (Laboratory of the Government Chemist, UK) Forensics has developed a robust STR profiling platform called the ParaDNA^® Intelligence Test System which can provide early tactical intelligence and aid investigators in making informed decisions on sample prioritization for detection. Here, we validated the ParaDNA intelligence test for its application in forensic cases using a range of mock evidence items following guidelines set by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Specifically, we tested the sensitivity and accuracy of the ParaDNA intelligence test, as well as the success rates for detecting mock samples and for use in case scenarios. Our findings demonstrate that the ParaDNA intelligence test generates useful DNA profiles, especially for samples such as blood, saliva, and semen that contain ample DNA, indicating the benefits of including ParaDNA as a prior step in forensic STR profiling pipelines.     

美国诱惑侦查制度及对我国的启示

美国社会执法实践中广泛存在诱惑侦查的使用，关于诱惑侦查的法律和制度规制经过长期演变和经验积累，形成了较为完整的诱惑侦查制度。本文通过对美国诱惑侦查制度的法律规定和具体实践的探究，以期为完善公安机关执法工作提供一些参考。我们应借鉴美国关于诱惑侦查方式运用的有益经验，加快有关诱惑侦查领域的立法进程，明确具体的法律规定。公安机关在执法实践中应正确认识诱惑侦查的合理性，慎用诱惑侦查手段，严格遵循程序执法，规范自身执法行为，积极改进执法方式。     

山羊支气管肺炎的计算机断层扫描影像研究

为了研究山羊支气管肺炎的计算机断层扫描(CT)影像表现,将10只山羊随机分为2组。试验组、对照组各5只,试验组通过气管内注射血清A型多杀性巴氏杆菌标准菌(4×10^8CFU/mL)人工诱发山羊的支气管肺炎,对照组注射等体积无菌PBS;观察接种前、后各组山羊的临床症状、体温及全血白细胞数等指标,并同时在接种前和接种后第1、3、5天对胸部进行CT扫描,比较两组影像学差异,观察山羊肺部病理解剖学变化。结果显示:接种前后体温、全血白细胞数差异显著;对照组CT影像接种前后未见异常;试验组影像多见两侧肺叶中下部呈现大小不等的片状或结节状的类似软组织密度影,边缘不清,肺纹理紊乱且模糊,支气管壁增粗,支气管扩张,呈"树芽征"及"轨道征"。结果表明,经气管内接种巴氏杆菌能够成功诱发支气管肺炎,CT影像与山羊支气管肺炎的临床表现密切相关,对山羊支气管肺炎的诊断具有较好的敏感度,有利于鉴别,应成为其较早期诊断的依据之一。
