Forensic Application of Analytical Mechanics in Fatal Fall From a Height

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.     

目标群体参与:精准扶贫政策执行领域形式主义的治理之道

精准扶贫政策执行领域形式主义问题突出,制约政策执行成效。欲破除其形式主义,目标群体参与不失为一种有效的治理路径。目标群体参与可促使精准扶贫政策执行从贫困村贫困户的客观实际出发,紧密联系贫困群众,克服政策执行中的“面子工程”现象,真正实现政策目标。目标群体在精准识别阶段整体参与水平偏低、精准帮扶阶段消极被动参与、贫困退出阶段参与功能弱化、脱贫考核阶段参与有效性不足等问题,引致在克服形式主义方面力有不逮。应在精准识别阶段提升目标群体整体参与水平,精准帮扶阶段提高参与主动性与能力,贫困退出阶段加强参与制度保障,脱贫考核阶段增强参与的有效性,以从根本上治理形式主义这一政策执行不良现象。     

Molecular Identification of Necrophagous Dermestes Species in South Korea Using Cytochrome c Oxidase Subunit I Nucleotide Sequences (Genus Dermestes)

Species identification of necrophagous insects found on a dead body is an essential key in applying medicolegal entomology to the estimation of postmortem interval (PMI). Due to limited morphological identification of insect evidence, several studies have identified species using molecular information such as DNA markers. While considerable cytochrome c oxidase subunit I (COI) gene sequence data of necrophagous fly species have been collected and annotated, those of necrophagous beetle species have not. Since necrophagous beetles such as Dermestes species have a larval period longer than that of flies, beetles are useful in even the late decomposition phase in estimating minimum PMI. To obtain the full-length COI gene sequences of six Dermestes species collected from South Korea, we designed primers for polymerase chain reaction amplification and sequencing. The obtained full COI nucleotide sequences were used for performing phylogenic analysis and comparison with previously reported sequences. The results demonstrated that the COI gene sequences could be used to identify forensically important Dermestes species in South Korea.     

劳模精神、劳动精神和工匠精神探析

党的十八大以来，在习近平总书记关于工人阶级和工会工作的系列重要讲话中，多次强调要坚 持弘扬劳模精神、劳动精神、工匠精神。认真领会劳模精神、劳动精神、工匠精神的科学内涵以及它们之间的 逻辑关系，对于实现中华民族伟大复兴的中国梦、增强文化自信和全面提升我国产业工人队伍整体素质有着重 大的理论价值和现实意义。劳模精神和劳动精神是整体和部分的关系，劳模精神和工匠精神是外力和内力的关系， 劳动精神和工匠精神是共性和个性的关系。总之，劳动精神，工匠精神，劳模精神存在逐步递进的逻辑。劳动 精神是成为人的精神，工匠精神是成为更加优秀的人的精神，劳模精神则是成为影响别人的人的精神。     

人体基因图谱与隐私权若干问题研究 ——保险公司是否应知晓投保人个人基因资料

生物技术的发展所揭示的人自身的秘密(尤其是个人基因图谱)在现代社会已不是一个纯技术问题,而是一个影响广泛的社会问题和法律问题,个人基因资料应当成隐私权保护的范围.现在条件下,保险公司不应要求被保险人的基因资料,投保人或被保险人单方面掌握自己基因资料也未必可取.投保人和保险公司之间可能就基因资料的使用进行博弈,具有信息优势的一方可能会出现道德风险.     

《史记》三"书"评议

<史记>篇目问题较多,而又以"八书"为甚.学界虽然对"八书"总体的看法没有什么分歧,但有三点需要注意:其一是<史记>缺少<礼书>、<乐书>和<兵书>,八篇中就有三篇有问题;其二是对<太史公自序>的几句话该怎么理解,<律书>和<兵书>的关系应是怎样的;其三是在司马迁创作"八书"的大前提下,上述三篇中是否还有后人搀入的部分.     

中国汉族与日本群体DYFl55S1基因座的遗传多态性

目的探讨Y染色体DYF155S1基因座的遗传多态性及群体间差异。方法 应用MVR-PCR、荧光显谱及DNA序列分析技术,对来自中国群体(北方汉族,64例)和日本群体(43例)男性个体的DYF155S1基因座进行初步分析。结果107例样本共检出了5种重复序列类型,包括新的命名为6型的重复序列,它是在1型的基础上T22A置换所形成,仅存在于日本群体,可作为民族特征性遗传标记。2群体重复序列的排列方式以3134顺序为主,在中国和日本群体中各占73.44％和67.44％,是黄种人的特点。134顺序在中国群体中占第二位,为17.19％,6134排列占日本群体的16.28％。3’端的4型重复序列的平均数目在日本群体为8.8条,明显低于中国群体的12.5条。结论DYF155S1基因座具有非常高的遗传多态性和明显的群体差异。     

刑事自由裁量权基本问题

刑事自由裁量权是指在刑事法适用过程中,涉及刑事法适用的官方人员在所适用的刑事法规则内容允许的范围内,有权在可以采取的多种行为中作出选择。刑事自由裁量权具有绝对性,同时也具有相对性。绝对性是指裁量行为是任意的,不受限制。相对性是指刑事自由裁量权仅仅是一种弱式自由裁量权。行使刑事自由裁量权的主体涉及公安人员、检察官和法官。公安人员和检察官行使的自由裁量权主要是依据刑事诉讼法的程序性权力。法官行使的自由裁量权除程序性权力之外,主要是依据刑法的实体性权力。     

IDENTIFYING THE PSYCHOLOGICAL FACTORS THAT MEDIATE THE ASSOCIATION BETWEEN PARENTING PRACTICES AND DELINQUENCY*

Past research has largely ignored the developmental changes within the child that account for the association between parenting and risk for delinquency. We used structural equation modeling and data from a longitudinal study of several hundred African‐American families to test the contentions of various theories regarding the sociocognitive and emotional factors that mediate the impact of parental behavior on a youth's risk for delinquency. Our findings largely supported the theories. The impact of monitoring/discipline was indirect through low self‐control and acceptance of deviant norms, whereas the effect of hostility/ rejection was indirect through low self‐control, hostile view of relationships, and acceptance of deviant norms. These two dimensions of parenting were no longer related either to affiliation with deviant peers or to conduct problems once the effects of these psychological characteristics were taken into account; the impact of these parenting practices was completely mediated by these four cognitive/affective variables. Contrary to expectation, however, these psychological factors did not mediate any of the relationship between caretaker involvement in antisocial behavior and child conduct problems.
