标识纠错法在擒拿格斗教学中的应用研究

标识纠错法是以标识纠错为形式、以强化刺激本体感觉为机理、以学员心理认知符合运动形式规律为目的的一种新型教学方法。标识纠错法操作简便易行,在擒拿格斗应用教学对比实验研究中,教学效果明显,学员的学习积极性和参与意识大幅提高。应加强公安院校警体教师在运动生理、运动生物力学等相关知识的学习,加快标识纠错法的应用和普及。     

浅议电子商务条件下商标权的法律保护

谈PHOTOSHOP在痕迹鉴定中的应用

利用PHOTOSHOP进行图形处理,就是一种数字图像增强技术,其处理的原图可以通过扫描仪进行获取也可以通过数码相机获取。PHOTOSHOP独特的图层功能为指纹和工具痕迹的鉴定提供了便利的条件,利用图层功能可以使指纹的特征描绘工作变得轻松,便捷并且更加准确。PHOTOSHOP的图层功能还能够实现对工具痕迹的拼接比对、对指纹的重叠比对。     

电烧伤皮肤金属元素的测定

本实验系用220V交流电源和直径2.0mm紫铜线为接触电极,在新鲜尸体腹部皮肤上做电烧伤实验。用原子吸收分光光度计对电烧伤皮肤中铜元素含量进行测定。结果表明电烧伤皮肤铜元素含量最高可达137.90μg/g。经10%福尔马林溶液固定40天以上的电烧伤皮肤铜元素含量有昕降低,但仍较正常皮肤含量为高。电烧伤皮肤铜元素含量以电流斑处为最高。本实验为电烧伤皮肤金属元素的定性与定量分析,检材的提取和处理,提供了一个较好的方法,有利于判定案件的性质和确定接触电极的金属种类。     

Patterned imprint mark due to the folded shoulder stock: A possible finding in contact shots from submachine guns

The muzzle imprint (barrel mark) is a pressure abrasion typically associated with contact shots. Apart from the contours of the actual muzzle profile, other constructional parts such as the front sight and/or the recoil spring guide of semiautomatic pistols may be imprinted next to the bullet entrance wound. In some types of submachine guns the shoulder stock can be folded forward so that its end partly encircles the muzzle. If such a weapon was in contact with the skin at the instant of discharge, a corresponding contusion mark is to be expected. The imprint configuration may point to the type of weapon and to the way in which the gun had been held when firing the shot. The paper presents the injury pattern in a 36-year-old man who committed suicide with a Scorpion SA Vz 61 submachine gun cal. 7.65 mm Browning from former Czechoslovakia.     

味觉商标的可注册性分析——以美国“欧加农案”为视角

20世纪90年代后期,随着经济的发展和技术的进步,商家越来越多地使用非传统商标作为营销手段以获取竞争上的优势。一般而言,非传统商标包括立体商标、颜色商标、声音商标、气味商标、动态商标、触觉商标、味觉商标等等。本文试图结合欧加农案对味觉商标的可注册性进行分析,其中包括对于味觉商标的显著性、味觉商标功能性以及味觉商标注册存在的主要问题的探讨,以期能为我国《商标法》第三次修改提供一些参考。     

对交通肇事逃逸案件中车体修复痕迹的检验与应用

交通肇事逃逸案件错综复杂,侦查线索少,对国内外的交通管理部门来说都是一个十分棘手的问题。尤其是针对肇事逃逸后经过修复的肇事车体,如何正确发现、分析和检验车体的修复痕迹,也就成了认定肇事车辆,追究肇事责任的重要途径和方法。     

内凹齿钥匙痕迹特征研究

目的运用光学仪器研究内凹齿钥匙痕迹形态特征。方法制作内凹齿钥匙正常开锁和被钥匙机复制后的样本,用光学显微镜拍照固定痕迹特征。结果内凹齿钥匙开锁痕迹特征明显,且被钥匙机复制后能留下复制痕迹。结论通过检验内凹齿钥匙上的痕迹特征能确定钥匙是否被复制过。     

咬痕个体识别的比对方法

目的 建立一个牙模数据库,为通过牙齿、咬痕进行个人识别的研究及其在法医实践中的应用提供一种新方法。方法 经过对400例牙模进行分析、计算,将牙齿的形状、排列转换成数字型(X,Y)坐标,通过计算出每颗牙关键点与坐标原点的相对位置,在DOS系统下运用Borland C++5.0语言编写程序,快速地计算出牙齿和牙弓的特征。结果 能对牙模进行自动识别,达到排除与认定。其比对精度长度为1.3mm,角度3°;可取的最少牙点位数目为12～14较为合理,大致需要5～7个完整的牙痕。结论 该方法是研究咬痕与牙模比对的基础。     

Defending the scientific foundations of the firearms and tool mark identification discipline: responding to recent challenges

Recent challenges have brought the discipline of firearms and tool mark identification to the forefront in recent court cases. This article reviews those challenges and offers substantial support for the scientific foundations of the firearms and tool mark identification discipline. A careful review of the available literature has revealed that firearms and tool mark identification is rooted in firm scientific foundations, critically studied according to the precepts of the scientific method culminating in the Association of Firearms and Toolmark Examiners' Theory of Identification. Firearms and tool mark identification has been validated in a manner appropriate for evidence of the kind to be expected in firearms and tool mark examinations. Proficiency tests and error rates have been studied and can provide consumers of the disciple with a useful guide as to the frequency with which misidentifications are reported in the community using appropriate methodologies and controls. As a result, the primary issues in recent challenges do not invalidate the firearms and tool mark discipline as a science nor should it detract it from its admissibility in a court of law.
