An assessment of the accuracy of discriminant function equations for sex determination of the femur and tibia from a South African population

The purpose of this study is to test the accuracy of seven discriminant function equations that have been derived by Steyn and Is?an for sex determination using measurements of the femur and tibia of South Africans of European descent (SAED). While the validity of some of the discriminant functions has been assessed by the authors who derived them, no previous independent study has been carried out to assess the accuracy of these equations. These equations have not been tested on skeletons located outside of the Gauteng province. A suite of measurements were taken on 272 femora and 256 tibiae obtained from four South African skeletal collections. The validity of each of the previously published equations for the femur was confirmed. However, two functions of the tibia showed low accuracy rates, most likely due to difficulties in recording the distal epiphyseal breadth measurement, and thus were found to be poor assessors of sex.     

Unidentified dead bodies: identification by means of an information-pool from dental data. Practical suggestions for a reformation of the collection and assessment of data of the masticatory system and their documentation (author's transl)]

The masticatory system has often proved very useful for the identification of unkown bodies. The technique of excising the mandible and the maxilla is explained. The evaluation and the preparation of models are described. For registration of the findings a new form has been developed. It is based on the old form "KP 16" as well as on the PA status.     

"Dr. Death" and the case for an ethical ban on psychiatric and psychological predictions of dangerousness in capital sentencing proceedings

Psychiatric and psychological predictions of dangerousness are used in a number of American jurisdictions to convince a judge or jury that a convicted murderer should be sentenced to death. Empirical research has demonstrated, however, that psychiatric and psychological predictions of dangerousness generally are inaccurate. This Article describes the current use of such predictions in capital sentencing hearings and examines their status under existing professional codes of ethics. It argues that the rendering of these predictions by psychiatrists and psychologists is contrary to the scientific and healing traditions of their professions and urges psychiatrists and psychologists to adopt an ethical ban on predictions of dangerousness in the capital sentencing context.     

徽州田野调查的个案分析——从“杀猪封山”看习惯的存留与效力

在中国传统的乡土社会里,法律渊源呈现出多元化的特征,除朝廷律令之外,传统习惯曾经是调整人们日常生活和民事行为的重要渊源。近几十年来,随着社会结构和社会性质的根本性转变,中国社会的法律与秩序也发生了深刻的变革。传统习惯在当代中国农村是否还存在?习惯是否与现代国家制定法相冲突?其在农村法治建设中的地位和作用怎样?这些问题都应引起我们法学研究的重视。通过对徽州农村民事习惯调查中的个案分析发现,在当今徽州农村仍然存留着大量的传统习惯,有些习惯甚至发挥着重要的法律效力。在当代中国农村的法治建设中,我们应当承认和重视发挥习惯的法律效力,探究那些“被冷落的真实”,为农村法治建设的发展寻找传统的动力。     

农民工养老保险参保行为及其影响因素分析——基于江苏五市(县)的调查数据

本研究基于江苏五市(县)调查数据,反映了农民工养老保险参保状况与模式,并对影响农民工参保的个体特征、外出打工原因、收入、流动性、制度、留城意愿六个方面的因素给出了解释.调查结果表明,当前农民工养老保险参保率低的问题主要是由制度障碍造成的,包括缴费年限太长、养老关系接续转移困难;个体特征中的性别和年龄影响比较显著,文化程度的影响相对较低;城市之间的流动性对参保行为的显著影响,说明养老关系接续转移存在的困难和农民工对养老保险制度的信任度不高.在进城之前,农民工的个体特征已基本成型,流动性强也是客观事实,因此,要提高农民工养老保险的参保率,须从破除制度障碍入手.     

论互联网平台反垄断的宏观定位——基于政治、政策和法律的分析

反垄断法的定位取决于其独特的价值、目标和功能。反垄断法自始即具有重大的政治经济使命,可以成为有着宏大价值目标和强大经济调整功能的"超级法"。互联网产业在资本、技术和商业模式上的独特性,使平台易于触角广泛和无序扩张,具有反垄断的高关联度。互联网平台反垄断首先要在宏观价值上拓展思路和提高站位,又要积极寻求恰当的法律和经济的技术性路径。我国互联网平台反垄断不能轻言和盲从当今美欧的表面趋势,不汲汲于引领潮流和贡献经验,趋势之下可能掩盖着不同的利益诉求,而要一切服从和服务于我国数字经济的实质性发展利益,既要及时、积极和到位,又要适时、适度和谦抑,并始终以促进我国互联网产业创新发展和提升国际竞争力为目标。互联网平台反垄断应当坚持法治进路,构建相应的规则体系,并确保客观、中立和理性,防止非理性和情绪化。

Cadmium-free quantum dots in aqueous solution: Potential for fingermark detection,synthesis and an application to the detection of fingermarks in blood on non-porous surfaces

The use of quantum dots (QDs) in the area of fingermark detection is currently receiving a lot of attention in the forensic literature. Most of the research efforts have been devoted to cadmium telluride (CdTe) quantum dots often applied as powders to the surfaces of interests.Both the use of cadmium and the nano size of these particles raise important issues in terms of health and safety. This paper proposes to replace CdTe QDs by zinc sulphide QDs doped with copper (ZnS:Cu) to address these issues. Zinc sulphide–copper doped QDs were successfully synthesized, characterized in terms of size and optical properties and optimized to be applied for the detection of impressions left in blood, where CdTe QDs proved to be efficient. Effectiveness of detection was assessed in comparison with CdTe QDs and Acid Yellow 7 (AY7, an effective blood reagent), using two series of depletive blood fingermarks from four donors prepared on four non-porous substrates, i.e. glass, transparent polypropylene, black polyethylene and aluminium foil. The marks were cut in half and processed separately with both reagents, leading to two comparison series (ZnS:Cu vs. CdTe, and ZnS:Cu vs. AY7). ZnS:Cu proved to be better than AY7 and at least as efficient as CdTe on most substrates. Consequently, copper-doped ZnS QDs constitute a valid substitute for cadmium-based QDs to detect blood marks on non-porous substrates and offer a safer alternative for routine use.
