Application of non-contact scanning to forensic podiatry: A feasibility study

Foot impression evidence recovered from crime scenes can be available in the form of barefoot prints, sock-clad footprints, or as impressions within footwear. In some cases, suspects leave their footwear at the scene of the crime, and the insoles from the footwear can be important in linking a person to the footwear. The application of 3D data-collecting technology is becoming more and more popular within forensic science and has been used to recover footwear impression evidence. The present study is a feasibility study to discover if 3D data capturing devices can be applied to insoles; to capture the footprint impression for measurement using the Gunn method (a method used in forensic podiatry casework). Three different methods of data capture were conducted; Adobe Photoshop, MeshLab, and calipers used directly on the insole. Paired t-tests and Intraclass Correlation Coefficient (ICC) were conducted for all three data capture methods. Seven measurements used in this study were significantly different across all three methods. ICC scores were moderate to excellent for the Photoshop method, poor to good for the 3D method, and moderate to excellent for the Direct method.     

青年人正常行走左右足底压力分布关系的研究

目的研究左右足底压力分布及变化规律，为利用现场左右足迹分析年龄等人身特点提供科学依据，也为足迹定量化分析与检验奠定基础。方法采用Footscan足底压力步态分析系统，选择30名青年男性，对其正常行走时足底压力分布数据进行采集、处理，运用SPSS12．0统计软件对左右足底6个区域的平均压强进行Pearson相关分析。结果左右足相应区域足底压力分布具有不同程度的相关性。结论正常行走左右足跟区压强相关性最好，在利用现场左右足迹分析年龄等人身特点时，应以跟区特征为主，其它区域特征辅助。     

闪光灯与足迹灯在足迹拍摄中的比较研究

闪光灯是一种最常见的摄影光源,但是在痕迹物证拍摄实际工作中却很少得到应用。无线引闪器可以把闪光灯与照相机分开单独使用,实现闪光灯的掠入射照明和侧光照明的目的,进一步提高了闪光灯的实用性。实验证实：与足迹灯相比,采用闪光灯照明配光,不仅可以在黑暗环境下,而且能够在明亮环境下对平面灰尘足迹和立体沙土足迹进行显现和拍摄,效果良好。因此,闪光灯在痕迹物证的拍摄中具有一定的推广和应用价值。     

赤足残缺足迹检验初探

刑事调解范围的建构

刑事调解制度是指在刑事案件中通过加害人与被害人之间面对面的接触,并经过充当中立的第三者的调解,促进当事方的沟通与交流,并确定犯罪发生后的解决方案。刑事调解具有自愿性、第三方的中立性、处理纠纷的灵活性、契约性等等。为真正实现刑事调解的制定目的,对过失犯罪案件、轻微伤害案件,初犯、认罪态度较好、社会危害性不大的且肇事方作有罪供述的,法定刑在三年以下的普通刑事案件案件以及刑事自诉案件可以进行调解。     

利用足迹足型特征分析性别的研究

本文收集252名成年男性和女性赤足足迹样本,对足迹长、宽、跟宽等几种稳定足型尺寸和拇外翻角度特征量进行测量、计算,统计男女足型的特点和分布规律,并利用t检验法对足长/足宽、足长/跟宽、足宽/跟宽等足迹足型特征比例关系的男女差异显著性进行分析,为利用足迹分析性别提供可靠依据。     

How do we provide the digital footprint with eternal rest? Some criteria for legislation regulating digital wills

This article analyses the implications of the death of digital service users on their digital footprint and assesses some of the solutions—contractual and legislative—that have been posited to date by digital service providers and by Parliaments of a few countries. In view of the different initiatives analysed, and the experience gained in their implementation, the paper presents legal certainty, effectiveness and transparency as criteria that should guide the regulation of the digital footprint in the case of death. These criteria must allow for the adoption or regulation of mechanisms for managing the digital footprint of digital service users to be clear and trustworthy for them and efficient and easily recognized and adopted by digital service providers.     

纺织物上灰尘足迹显现实验探讨

纺织物中所用的纤维种类很多,一般分为天然纤维和化学纤维两大类。涤纶纤维是化学纤维中最常见的一种,涤纶被大量用于外衣、衬衣、裙料、窗帘、台布、蚊帐布等。本文以涤纶布为承痕客体,以此来研究化纤类纺织物上灰尘足迹的显现提取方法。
