论刑事诉讼中的精神疾病司法鉴定

刑事诉讼中的精神疾病司法鉴定通常在＂有鉴定必要时＂启动,精神疾病司法鉴定人出席庭审,鉴定意见在法庭上接受质证,但是法官并不完全受制于鉴定意见。我国刑事诉讼中精神疾病司法鉴定属于职权型启动,当事人的相关权利保障不足,精神疾病司法鉴定的意见难以在庭审时接受充分质证,对精神疾病司法鉴定意见的采信缺乏统一的规则。应当加强我国司法机关运用职权启动精神疾病司法鉴定的义务,鉴定人原则上应当出庭,并规范法官对精神疾病司法鉴定意见的采信。

测量笔画增宽度判断激光打印文件朱墨时序初探

目的考察印章印文与激光打印字迹交叉部位的笔画增宽现象,得到朱墨时序判断依据。方法制作两种朱墨时序的实验样本,在VSC-6000文检仪下观察,读数显微镜在相同放大倍率测量,记录增宽度,比较同种品牌印文色料在两种时序下笔画的增宽度。结果相同保存条件下同种品牌印文色料不同时序盖印的实验样本都有增宽现象,先墨后朱时序下增宽度较大。结论该方法可以作为朱墨时序判断依据。     

论国家统一司法考试对法学本科教育的影响

司法考试是律师、法官和检察官的资格考试,是职业教育的一个组成部分。在我国法学院校,司法考试已经成为影响本科教学的一个十分重要的因素。本科阶段的法学教育有"应试教育"的趋势,课堂教学慢慢演变成"司法考试培训班",这背离了法学本科阶段的教育宗旨。法学本科阶段的教育宗旨是通识教育,职业教育应当在后本科阶段进行。因此,在本科阶段的教育中,应当尽可能减少司法考试的影响。

台湾地区情报理论研究的现状与特点管窥——以“中央警察大学”硕士研究生入学考试试题为例

近十年来,台湾＂中央警察大学＂情报学硕士研究生入学考试试题的考察重点主要集中在以下几个领域：冷战后尤其是＂9.11＂事件以来的情报改革与情报转型问题、情报控制问题、情报基础理论、现实情报工作。通过对试题及其考察重点的分析,可以发现台湾地区情报理论研究有如下特点：注重引进与借鉴西方尤其是美国的情报理论及实践成果、注重情报控制与＂国家＂安全法制化问题研究、注重情报与非传统安全及国土安全等安全问题研究、注重情报理论研究和情报实践的结合与互动。     

网络考试系统在我院教学中的应用研究

开设多波段光源发现痕迹的实验

多波段光源已广泛应用于痕迹检验、现场勘察等领域,是公安机关侦破案件的一个重要武器。公安院校刑侦、刑技专业的学生,通过做多波段光源发现痕迹的实验来掌握该项技术很有必要。     

Fatal Intoxication with α‐PVP,a Synthetic Cathinone Derivative

This study presents the fatal case of a young man who was admitted to the ICAU due to sudden cardiac arrest. An interview revealed that the patient had taken some unspecified crystals. From the moment of admission, his condition deteriorated dramatically as a result of increasing circulatory insufficiency. After a few hours, sudden cardiac arrest occurred again and the patient was pronounced dead. In the course of a medicolegal autopsy, samples of biological material were preserved for toxicology tests and histopathological examination. The analysis of samples using the LC‐MS/MS technique revealed the presence of α‐PVP in the following concentrations: blood—174 ng/mL, urine—401 ng/mL, brain—292 ng/g, liver—190 ng/g, kidney—122 ng/g, gastric contents—606 ng/g. The study also presents findings from the parallel histopathological examination. Based on these findings, cardiac arrest secondary to intoxication with alpha‐PVP was determined as the direct cause of the patient's death.     

The Relationship Between the Surface Morphology and Chemical Composition of Gunshot Residue Particles

In this study, chemical composition and morphology of gunshot residue (GSR) of 9 × 19 mm Parabellum‐type MKE (Turkey)‐brand ammunition were analyzed by scanning electron microscope and energy dispersive X‐ray spectrometer. GSR samples were collected by “swab” technique from the shooter's right hand immediately after shooting. According to general principles of thermodynamics, it is likely that the structures will have a more regular (homogeneous) spherical form to minimize their surface area due to very high temperatures and pressures that occur during explosion. Studied samples were collected under the same conditions with the same original ammunition, from the same firearm and a single shooter. This is because many other variables may affect size, structure, and composition in addition to the concentrations of elements of the structure. Results indicated that the chemical compositions are effective in the formation of GSR morphological structures.
