Application of non-contact scanning to forensic podiatry: A feasibility study

Foot impression evidence recovered from crime scenes can be available in the form of barefoot prints, sock-clad footprints, or as impressions within footwear. In some cases, suspects leave their footwear at the scene of the crime, and the insoles from the footwear can be important in linking a person to the footwear. The application of 3D data-collecting technology is becoming more and more popular within forensic science and has been used to recover footwear impression evidence. The present study is a feasibility study to discover if 3D data capturing devices can be applied to insoles; to capture the footprint impression for measurement using the Gunn method (a method used in forensic podiatry casework). Three different methods of data capture were conducted; Adobe Photoshop, MeshLab, and calipers used directly on the insole. Paired t-tests and Intraclass Correlation Coefficient (ICC) were conducted for all three data capture methods. Seven measurements used in this study were significantly different across all three methods. ICC scores were moderate to excellent for the Photoshop method, poor to good for the 3D method, and moderate to excellent for the Direct method.     

青年人正常行走左右足底压力分布关系的研究

目的研究左右足底压力分布及变化规律，为利用现场左右足迹分析年龄等人身特点提供科学依据，也为足迹定量化分析与检验奠定基础。方法采用Footscan足底压力步态分析系统，选择30名青年男性，对其正常行走时足底压力分布数据进行采集、处理，运用SPSS12．0统计软件对左右足底6个区域的平均压强进行Pearson相关分析。结果左右足相应区域足底压力分布具有不同程度的相关性。结论正常行走左右足跟区压强相关性最好，在利用现场左右足迹分析年龄等人身特点时，应以跟区特征为主，其它区域特征辅助。     

低碳生态城市视阈下的环境保护问责制构建

伴随着全球碳排放量的迅速上升，低碳生态城市建设模式势在必行。分析低碳生态城市的基本内涵及建设低碳生态城市的可能性和必然性，为政府在城市管理方面提供了新的思路。要通过制度创新，完善责任监督体系，加强考核和建立惩奖机制，以善治理念为指导来建立和完善我国的环境保护问责制，营造绿色、高效、和谐、健康、可持续发展的城市。     

Research of China＇s Development Dilemma and Countermeasure of CDM Project in ＂Post-- Kyoto Era＂

＂后京都时代＂我国CDM市场可谓机遇与挑战并存。主要存在项目类型分布不合理、最终签发成功率低、融资渠道单一、缺乏科学合理的碳贸易体系等问题,因此政府相关部门应推出鼓励政策引导CDM项目协调发展;培育咨询机构、提高项目申报通过率;加快我国＂碳金融＂建设与改革,为CDM项目提供更多融资渠道选择;构建科学合理的碳贸易体系,以促进我国节能减排工作和CDM市场科学、健康、持续发展。     

Trends in suicide by carbon monoxide inhalation in King County, Washington: 1996-2009

Carbon monoxide (CO) inhalation is one of the leading methods of suicide in the United States. A sharp increase in suicide by inhaling the CO produced from burning charcoal has been reported in parts of Asia; however, the incidence of this method has not been determined in a U.S. population. Thus, we determined trends of CO suicide in the ethnically diverse population of King County, Washington, U.S.A. During the period 1996-2009, we identified 158 cases of suicide by CO poisoning, with 125 because of automotive exhaust, 26 because of charcoal burning, and seven from other CO sources. While historical U.S. data indicate >99% of CO suicides in the United States occurring by automobile exhaust inhalation, in the most recent years analyzed, c. 40% of CO-related suicides in King County, Washington, were because of charcoal burning, indicating a possible shift in suicide trends that warrants further scrutiny in additional populations.     

国际碳排放权交易及其对我国的启示

全球气候变化对各国产生了一系列的影响,碳排放权已成为新兴的交易客体,国际碳排放权的产生与发展,既为我国带来机遇,也使我国面临挑战。我国碳排放权交易市场尚处于起步阶段,建立与完善我国碳排放市场机制显得尤为重要与迫切。因此,我们应当借鉴国际碳排放权交易的经验,从法律、政策、信息透明度、政府职能等方面进行改进。     

当前低碳经济发展困境及我国低碳经济发展的法律保障简

发展低碳经济已成为世界各国的主流意识形态和价值现.低碳经济有着独特的优势和巨大的市场潜力,已成为世界经济发展的热点和重心.然而在国际上,由于碳减排义务的分担存在分歧以及欧盟碳交易市场的低速而使低碳经济深陷困境.我国低碳经济建设迫切而任重,结合我国低碳经济发展的现实,构建完善的法律框架和相应的配套保障制度是必由之路.     

Cheikh Anta Diop: The social sciences,humanities, physical and natural sciences and transdisciplinarity

ABSTRACT

This article presents a critical exposition of the contributions of Cheikh Anta Diop to a scientific understanding of ancient African history, race, and the study of culture. It sets out the history of Diop's successful struggle against flawed Eurocentric scholarship which sought to deny the contributions of ancient black Egyptians to world civilisation. Diop's intellectual odyssey across physics, linguistics, through anthropology, ethnology, genetics and history is recounted here to demonstrate the limitations of mono-, inter- and multidisciplinarity and clearly identifies him as a pioneer of transdisciplinarity in the field of knowledge production.     

Subarachnoid Hemorrhage and Carbon Monoxide Exposure: Accidental Association or Fatal Link?

This case study reports a fatal subarachnoid hemorrhage (SAH) with concomitant accidental carbon monoxide (CO) exposure in 32‐year‐old man. Autopsy results indicated an antemortem aspiration of smoke, and a massive SAH was identified as the cause of death. Intriguingly, the carboxyhemoglobin level was 30%, suggesting that CO could have played a specific role. Intracranial hemorrhages following CO exposure in brain areas and tissues such as the basal ganglia, globus pallidus, or white matter are rare, but well characterized, whereas SAH related to CO exposure has not been previously described. In this case report, the possible role of CO, either as a primary cause or as a facilitating factor, in the pathogenesis of SAH is discussed. In particular, we propose the hypothesis that the excessive vasodilating effects produced by CO on the cerebral endothelium results in consequential loss of microvascular integrity.     

铜导线一次和二次短路熔痕的显微共聚焦激光拉曼光谱特征研究
