论域名与商标权冲突的解决

随着互联网民用化和商业化进程的不断发展,域名与商标权之间的冲突也愈演愈烈,目前国际上域名争议的解决途径主要有两种:一是通过民间专门争议解决机构司法外解决,一是司法解决。目前,我国对域名与商标权冲突的法律调整较之以前已有很大进步,但仍有需完善之处:对于域名与商标权产生冲突的源头,仍旧没有作出规定;调整域名纠纷中的法律效力的位阶较低;现有的法律法规对商标侵犯在先,域名权该如何处理没有提及。

Relatively Permanent Pigmented or Vascular Skin Marks for Identification: A Pilot Reliability Study

In child sexual exploitation offenses, the collected evidence images often show the skin of nonfacial body parts of the criminals and victims. For identification in this scenario, “relatively permanent pigmented or vascular skin marks,” abbreviated as RPPVSM, were recently introduced as the basis for a novel biometric trait. This pilot study evaluated the interexaminer variability of RPPVSM identification. Four dermatology physicians were recruited to examine RPPVSM from 75 skin images collected from a total of 51 Caucasian and Asian subjects. The images were separated into 50 reference (“suspect”) images and 25 evaluation (“evidence”) images. The examiners were asked to perform identification by annotating RPPVSM in each of the 25 evaluation images and matching them with the reference images. The rate of misidentification was 0% while the mean rate at which examiners failed to find a match was 6%, indicating the potential of dermatology physicians performing the role of RPPVSM examiners.     

对文件绝对形成时间的综合检验

在理论上,文件一定能反映出某种时闻信息,这为人们鉴定文件形成时间提供了可能性。文检工作者通常采用理化方法进行文件形成时间的检验,但该方法常受制于纸质、色料、保管条件等,因此在实践中并非每份文件都能够检验出形成时间。对于不具备理化检验条件的案件,应该分析文件时间特征,进行综合检验,以确定文件的绝对形成时间。     

扫描电镜/X射线能谱仪检验电流斑规范化方法探讨

目的探讨电流斑皮肤金属化的机理、检材提取处理和扫描电镜/能谱仪检验规范化方法,对检验结果进行分析和价值判断。方法用扫描电镜/能谱检验,采用低倍大窗口覆盖损伤区域采集平均元素能谱图,并在可能的金属元素富集区域寻找球形金属颗粒。结果扫描电镜下可观察到散在的孔穴、细胞碎屑、龟裂、裂隙等特征,有些电流斑可检出金属元素,其中部分电流斑可发现球形金属颗粒。结论采用规范化的检材提取、处理和检验方法可消除随意性方法造成错检的可能。电流斑皮肤上异常含量的金属附着可支持病理检验符合电流斑表现的结论,同时也为电击导体的推断和金属元素成分比对提供依据。球形金属颗粒的发现揭示存在电弧高温的可能性极大,可强力支持病理检验符合电流斑表现的结论。     

Virtual Tool Mark Generation for Efficient Striation Analysis,

This study introduces a tool mark analysis approach based upon 3D scans of screwdriver tip and marked plate surfaces at the micrometer scale from an optical microscope. An open‐source 3D graphics software package is utilized to simulate the marking process as the projection of the tip's geometry in the direction of tool travel. The edge of this projection becomes a virtual tool mark that is compared to cross‐sections of the marked plate geometry using the statistical likelihood algorithm introduced by Chumbley et al. In a study with both sides of six screwdriver tips and 34 corresponding marks, the method distinguished known matches from known nonmatches with zero false‐positive matches and two false‐negative matches. For matches, it could predict the correct marking angle within ±5–10°. Individual comparisons could be made in seconds on a desktop computer, suggesting that the method could save time for examiners.     

自含墨印章印文盖印时间受老化条件的影响

目的探索利用气相色谱法较精确、定量测定自含墨印章印文盖印时间受人为老化条件的影响。方法分别在恒温烘烤、紫外线照射、纯水浸泡等人为老化条件下,测定自含墨印章印油中所含有的主要相关溶剂成份的含量变化。结果得出了主要溶剂成份在人为老化条件下其含量的变化规律以及人为老化与自然老化的对应关系。结论利用气相色谱法可以对不同保存条件下自含墨印章印文的盖印时间进行测定,为实际相关案件的检验提供了依据。     

利用红外显微镜无损检测圆珠笔油墨色痕的研究

在这个研究中,红外显微镜聚焦功能得到了充分验证。该研究采用的检测方法是通过红外显微镜将红外光斑直接聚焦在样品表面,采集其红外光谱。根据样品红外吸收峰的个数、位置、强度及形状进行定性分析,以达到区分相同颜色不同品牌的圆珠笔油墨色痕的研究目的。研究结果表明,采用的检测方法可有效区分相同颜色不同品牌的圆珠笔油墨色痕。而且该检测方法具有无损检测特点,保持了物证的原样性。     

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.     

Organizing a Proficiency Testing Program on Stamp Impressions Examination in Accordance with ISO/IEC 17043 Requirements

Stamps and stamp impressions examinations are based on matching defects and design details on the questioned and control samples. These examinations are routinely carried out by document examiners around the world. International proficiency tests for questioned documents examination have been available for decades while similar programs specifically focusing on stamp impressions examination are rare. This study reported a recent proficiency testing program on stamp impressions examination organized by an accredited provider in accordance with ISO/IEC 17043 requirements. Twenty‐four forensic laboratories registered for the program. Apart from giving details on the design and operation of the program, this study also aimed to provide the limitations and difficulties encountered in sample preparations, homogeneity, and stability tests of the testing materials. Various comments and feedbacks received from the participants, particularly in respect of examination approaches, challenges faced by the participants in forming conclusions and their suggestions for further improvement would be evaluated.
