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.     

Effect of Wind on Horizontal Displacement of Fatal Fall from a Height

The horizontal displacement of the human body resulting from fatal fall from a height is an important variable commonly used to inversely determine the cause or identify other forensic aspects of the fall. When examining the horizontal displacement, the wind effect is generally ignored. This technical note reports analytical modeling of the falling process, utilizing previous measurements of wind force acting on the human body, for determining the functional relationship between the wind speed and the horizontal displacement in the falling process. The result reveals that it does not take extremely rare wind conditions to cause a considerable shift of the human body, highlighting the importance to consider wind as a factor in investigations of fatal falls.     

Managing commercial risks in open source software licensing

Legal context: The article reviews the commercial risk allocation clauses intypical open source licence terms and discusses their enforceabilityand implications. Key points: The enforceability of warranty disclaimers and limitation ofliability clauses in common open source licence terms is questionable,particularly in a cross-border context, and commercial licensorsshould take additional steps to protect themselves from down-streamrisks. Practical significance: Open source software presents a number of unusual commercialissues, because it is available free of charge and the providerstry to disclaim warranties and liabilities. End users and resellershave to adjust their own in- and out-licensing models to accommodatethis situation.     

20世纪90年代以来的近代中国妇女史研究综述

20世纪90年代以来的近代中国妇女史研究取得了令人可喜的成果,成立了一批研究机构和学会,扩大了研究领域和范围,更新了研究视角和方法,发表、出版了可观的论著,从而促进了整个史学的发展。但就总体水平而言,高质量、高水准的成果并不多见,妇女史作为历史学科的一个分支学科,并未引起足够的重视,主要是资料的不足、分散,限制了近代中国妇女史研究的进一步拓展和深化。要真正确立妇女史的学科地位,尚需学术界的艰辛努力。     

泰国：20世纪二三十年代海外潮剧的中心

泰国潮剧源于中国。20世纪二三十年代,伴随着现代化的进程,泰国潮剧逐渐本土化,并对中国潮剧产生一定的影响,成为海外潮剧的中心,对潮剧艺术的发展做出了巨大的贡献。同时,潮剧在泰国与中国之间的地理位移意味着这一特殊戏曲艺术在整体格局中的边缘与中心地位的互换,其后隐藏着特定的社会背景和历史渊源,给予人们深刻而独特的文化启示。     

技术性贸易壁垒中贸易和环保的平衡

技术性贸易壁垒的合法、合理、适度使用已经成为当今WTO框架内涉及贸易自由化和环保平衡的重要问题之一。GATT第XX条为部分涉及环保的技术性贸易壁垒实施设立了条件和要求。《TBT协定》为涉及环保的技术性贸易壁垒的实施设立了指导原则和判断标准,但这些原则和标准的适用则是一个复杂的技术和法律的冲突和协调过程,贸易保护之目的和效果都会影响技术性贸易壁垒实施过程中贸易自由和环保措施之间的平衡。     

专业色彩风景写生教学特色分析

专业色彩写生教学应根据专业基础、专业特色和专业岗位能力需求,来确定不同的课题内容。教学计划和教学方式应凸显观念创新和技法创新,努力做到按岗位能力要求来施教育才。     

对20世纪50年代中国宪法学基本范畴的分析与反思

一门学科的生命力首先表现在基本范畴与学术规范的确立。宪法学作为研究宪法现象的知识体系,应确立表明其独立学科地位的范畴与学术话语。中国宪法学发展正处于社会转型期,需要认真反思5 0年来宪法学范畴发展的历史过程,以中国社会的发展为背景,建构中国宪法学基本范畴。     

中国民法现代化历程中的三个误区

清末民初开始的中国民法现代化历程,在确立平等、自由、秩序等现代民法精神,构筑当代民法制度发展基本脉络的同时,尚存有一些遗憾与不足,以下三个历史误区更值得关注:民法现代化初期的民法价值理念,不恰当地追随了西方的“权利社会化”思潮;民法现代化历程始终未能摆脱国家本位主义的阴影;民法制度的创制过度突出了“制定法”地位与“法律移植”的作用。为此,我们需要进一步反思这一百年的民法现代化历程之得失,以期重新展望、描绘更为美妙的民法现代化图景。     

唐代工商业利润的流动转化及其社会后果

唐代官营工商业利润主要流入政府财政 ,也有一部分转化为高利贷资本和用于土地经营。民间工商业利润除了一部分用于生活消费、交通权贵和囤积射利外 ,大多用于土地的购买兼并和转化为高利贷资本。官、私工商业利润向产业资本流动转化甚少 ,既无益于新的生产方式的产生和发展 ,也拉大了财富占有上的贫富分化 ,并最终激化了社会矛盾和阶级矛盾 ,导至农民大起义爆发 ,唐王朝的腐朽统治遭到推翻
