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.     

Defenders of Freedom or Perpetrators and Facilitators of Crimes? Beyond Progressive Retreatism in the Trump Era

ABSTRACT

Heavily influenced by broad definitions of crime developed by a few pioneering critical criminologists, the main objective of this article is to provide evidence showing that the current Trump administration is a regime that commits crimes of the powerful and facilitates some types of interpersonal violence in private places. Special attention is devoted to direct and in-direct state-perpetrated violent crimes against women.     

不同茯苓提取物对急性肝损伤小鼠的保护作用

目的 研究茯苓不同提取部位对四氯化碳（carbon tetrachloride，CCl4）所致急性肝损伤的保护作用，并探讨其可能的作用机制。方法 〖JP2〗将120只昆明小鼠随机分为正常组，模型组，阳性药物组（水飞蓟素100 mg/kg），茯苓水提物低、中、高剂量组（30、60、120 mg/kg），茯苓醇提物低、中、高剂量组（25、50、100 mg/kg）以及茯苓多糖低、中、高剂量组（10、20、40 mg/kg），连续灌胃两周后腹腔注射0.5% CCl4溶液诱发小鼠急性肝损伤。模型复制12 h后处死小鼠，检测血清中谷氨酸氨基转移酶（alanine aminotransferase，ALT）、天冬氨酸氨基转移酶（aspartate aminotransferase，AST）和肝组织中超氧化物歧化酶（superoxide dismutase，SOD）、丙二醛（malondialdehyde，MDA）及白细胞介素-1β（interleukin-1β，IL-1β）、白细胞介素-6（interleukin-6，IL-6）和肿瘤坏死因子-α（tumor necrosis factor-α，TNF-α）水平；苏木精-伊红染色观察肝组织病理切片。结果 各给药组肝组织病理损伤减轻。与模型组比较，各给药组小鼠ALT、AST、MDA、IL-1β、IL-6和TNF-α水平均显著降低（P<0.05），SOD活性显著升高（P<0.05），且茯苓多糖的作用呈剂量依赖性，以茯苓多糖高剂量组最接近阳性药物组。结论 3种茯苓提取物对CCl4诱导的小鼠肝损伤均具有不同程度的保护作用，以茯苓多糖效果最为显著，其机制可能与增强肝脏抗氧化能力及减轻炎症有关。     

新就业形态劳动者的劳动权益保障 ：内容、现状及策略

新就业形态劳动者的劳动权益保障问题已成为政府和社会公众密切关注的重要问题。新就业形 态劳动者的劳动权益包括劳动就业权、劳动报酬权、劳动条件权和劳动救济权 4 类，并可以细分为 13 项权利。 本研究以外卖骑手为代表，进一步分析了新就业形态劳动者劳动就业权、劳动报酬权和劳动条件权中的社会保 障权的现状。研究发现，新就业形态劳动者的劳动就业权、劳动报酬权和社会保障权相比该群体劳动者的平均 情况都得到了改善。研究认为提升新就业形态劳动者的劳动权益保障水平需要更复杂的策略行动，包括继续发 挥好市场作用、处理好短期与长期的关系，以及政府与平台企业协同治理等。     

赫哲族伊玛堪代表性传承人生命历程研究——以尤文凤为个案

伊玛堪是赫哲族世代相传的民间说唱艺术形式,2011年被列入联合国教科等“急需保护的非物质文化遗产名录”。运用生命历程理论,结合观察和深度访谈法,选择省级赫哲族伊玛堪代表性传承人尤文凤为个案,考察其学习、传承伊玛堪的具体过程,提出伊玛堪的传承与保护既需要作为个体生命的代表性传承人发挥主观能动性,也需要政府、市场、专家学者、媒体等多种社会力量与其协同合作。     

‘Let's Win this Game Together’: Children's Rights Violations,Macro‐Securitisation and the Transformative Potential of the 2014 FIFA World Cup in Brazil

Sport's transformative potential is known to support marginalised children, to deal with traumatic experiences and instil positive values; yet hosting mega sporting events (MSEs) can have negative impacts. Drawing on participatory research with favela‐based children during the 2014 World Cup in Brazil, this article argues that MSEs bring a macro‐securitisation of urban life, which causes considerable harm. This paper also suggests that the inclusion of children's voices in advocacy debates can challenge top‐down securitisation and might allow MSEs to foster further positive social transformation. Therefore, juxtaposed with causing harm, macro‐securitisations can open opportunities for children to take action and have their voices heard.     

法医学尸体检验职业防护指南(建议稿)

法医工作者的职业暴露风险极大,案件现场及尸体上的有毒有害物质、高致病性微生物以及利器、骨折等因素均可能给法医带来身心伤害甚至生命危险。随着经济社会发展,法医的工作环境已经较过去显著改善,但是针对个人防护的重视程度仍需提高。近年来公共卫生事件频发,给法医职业防护带来新的挑战,迫切需要借鉴生物安全领域的先进技术和防护理念,以满足新形势下法医工作的需要。本指南立足当前法医职业防护的实际需求,从暴露风险、防护分级、应急处置等角度阐述,希望能为制定法医职业防护相关标准提供参考,以指导法医工作者开展个人防护工作,为提升法医职业化水平和身心健康提供帮助。     

Opposition to immigration in contemporary Russia

The study examines sources of opposition to immigration in contemporary Russia. It distinguishes between two types of opposition to immigration: exclusionary attitudes based on national membership and exclusionary attitudes based on race or ethnicity, directed exclusively at foreigners with non-Slavic or non-European origins. Findings indicate that a quarter of ethnic Russians can be classified as “racial exclusionists”; they are willing to admit immigrants who share a race/ethnic group with most of Russia’s people but object to the admission of racially/ethnically different immigrants. Another 42% of ethnic Russians are classified as “total exclusionists”; they object to immigration of all foreigners, regardless of their race/ethnicity. Multivariate analysis focuses on the impact of perceived collective vulnerability, human values, and socio-demographic attributes. Opposition to immigration in Russia is further situated within temporal and cross-national comparative perspectives. Apparently, exclusionary attitudes toward immigrants who share a race/ethnicity with most Russians increased between 2006 and 2016.     

国际投资仲裁机构对涉及人权问题的投资纠纷的审理

国际投资仲裁的当事人在仲裁中提出人权方面诉求的情况在最近十几年里缓慢地增加了,仲裁庭只有在仲裁管辖条款能够覆盖人权问题,并且当事人所选择的适用法能够为人权问题的解决提供指引的情况下,才能就与投资有关的人权纠纷做出裁决。现有的国际投资仲裁机构自身存在很多缺陷,不适宜作为审理与投资有关的人权问题的理想场所。我国应该支持与投资有关的人权问题主要通过东道国的司法途径进行救济。
