Validation of chest X-ray comparisons for unknown decedent identification

Comparing skeletal structures between antemortem and postmortem chest radiographs is widely used by forensic specialists from many disciplines to positively identify unknown decedents. However, validity assessments of this method have been fairly limited. This study had three objectives: 1) to quantify the reliability of ante- and postmortem chest radiograph comparison for decedent identification; 2) to identify useful radiologic features supporting decedent identification; and 3) to recognize sources of error in decedent identification related to use of comparative radiographs. A forensic pathologist, a forensic anthropologist, and two radiologists participated in the study. Our results showed that chest radiograph comparisons proved reliable, if basic decedent information was provided, and antemortem and postmortem radiographs were adequately positioned and exposed. A "morphological approach" using normal anatomical structures for comparison may provide the most efficient method for accurate identification.     

Evaluation of some oxygen, sulfur, and selenium substituted ninhydrin analogues, nitrophenylninhydrin and benzo[f]furoninhydrin

Six ninhydrin analogues containing oxygen, sulfur, and selenium substituents at the C-5 position, 5-(4-nitrophenyl)ninhydrin, and benzo[f]furoninhydrin were evaluated as fingerprint development reagents. The analogues all showed good fingerprint color development but were not superior to ninhydrin in this respect. The benzo[f]furoninhydrin complex was strongly luminescent at room temperature following zinc complexation, while the remaining analogues required cooling to -196 degrees C to produce optimum luminescence. The benzo[f]furo, nitrophenyl, and methyl selenide analogues showed the best potential as fingerprint reagents with the benzo[f]furo analogue comparing favorably with DFO.

犯罪心理学研究中运用量化方法引起的理论思考

量化与统计分析是一项重要的研究方法,在犯罪心理学研究中得到了广泛运用,同时也存在着使用的局限性。犯罪人有很强的心理掩饰性,对包括犯罪人在内的人的心理的测量实际上是一种间接测量,测得的数据是心理学家标定的数据,兼有客观性与主观性。量化研究如果不与科学思维相结合,有可能得出浅薄平庸甚至错误的结论。心理学研究应当以“人性”为基点,多种方法综合运用,实现量化方法与非量化方法的有机结合。     

论计算机犯罪的侦查机构建设

反思我国现存计算机犯罪侦查机构存在的诸多问题,我们不难发现我国与国外计算机犯罪侦查工作开展的比较好的国家还存在着很大差距,这些国家的计算机犯罪侦查机构为我国计算机犯罪侦查机构的建设提供了借鉴和参考。就我国计算机犯罪侦查机构建设的改革方向而言,我们应先着力修正一些外在性的制度的缺陷并着意完善之。     

The Israel and Palestine land settlement problem, 1948–2005: An analytical history

This paper traces the history of the current conflict between Israel and Palestine from 1948–2005 C.E. It focuses on the frontier conflict between Israel and Palestine, a conflict that has resulted in four major wars during the post-Second World War period, and that has left Israel as the occupying power over a large swathe of territory not allocated to it by the United Nations in 1947. It outlines the nature of the refugee problem in Palestine and neighboring Arab states, and defines the political problems posed both by relative Israel-Palestine population growth, and by the `right to return’ claim by ousted Palestinian Arabs. It reviews the political problems posed by religious extremism and theocratic government both in Israel and Palestine. It concludes with a brief discussion of the unpleasant alternatives left as the road map to peace disintegrates and outlines a preferred solution from the perspective of the advanced western nations.     

浅析CEPA原产地规则

内地自2004年1月1日起,对原产香港进口金额较大的273个税目的产品实行零关税。由此,界定香港产品“原产地”规则及其签证核查程序成为实施零关税的前提。虽然CEPA附件2《原产地规则协议》对判定香港原产货物给出了认定标准,但这只是一个开端,因为根据中国加入世贸组织的承诺,以后要向更多的国家与地区开放零关税,都会涉及到原产地认定问题。因此,从一定意义上讲,CEPA原产地问题是中国运用世贸组织规则走向纵深的一次预演。

借鉴国外经验完善我国西部大开发的财税政策

西方发达国家在开发落后地区,实现区域经济协调发展的过程中,不但重视运用市场这只“看不见的手”进行调节,而且特别注意采取特殊的有利于缩小地区差距的区域发展财税政策,依靠市场和政府干预的办法加速对边远落后地区的开发,消除区域发展差异。作为借鉴,我国财税政策要适当调整,从而更好地贯彻西部大开发战略。     

北京高校体育课实行运动处方教学的实验研究

运动处方教学与常规体育课教学效果不同,它是一种可以切实锻炼身体和培养锻炼能力的新型教学模式。运动处方教学模式以运动处方教学作为主要手段去完成体育教学中的主要任务,并以运动处方教学为主要方式解决众多与体质发展相关的问题。运动处方教学模式可在提高学生身体素质的同时培养自觉锻炼能力。
