Separation of overlapping fingermarks by Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging

Latent fingermarks are impressions of the skin ridge pattern that are transferred by the accidental contact of fingertips with a deposition surface. The ability to enhance, lift and produce an image of a latent fingermark, for comparison and suspect match against a central fingerprint database, provides forensic investigators with what is still considered one of the most powerful means of biometric identification to date. Identification relies on the recovery, visualisation, extraction and comparison of local characteristics of the ridge pattern (minutiae) that are unique to individuals. Therefore, both for manual inspection of the minutiae and using automated ridge extraction algorithms, the clearer the ridge details, the more reliable and successful the match. Overlapping fingermarks pose a remarkable challenge in this context and are often encountered when developing marks from crime scenes. Here we propose the use of Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging (MALDI MSI) to separate overlapping fingermarks using ion signals that are characteristic of each fingermark and that may be endogenous or exogenous in nature. In this work we show that the methodology works in a number of different scenarios both using manual inspection of the spectrum profile or a much quicker multivariate statistical analysis.     

《大国政治的悲剧》与米尔斯海默的悲剧

约翰.米尔斯海默的《大国政治的悲剧》确实是一个悲剧,它是米氏带着悲观主义有色眼镜审视国际政治的必然结果。米氏自身天生的悲观主义来自于他的文化背景、经历和美国学者的心理优势。     

协调之美:上海世博会事务协调局协调工作探究

中国2010年上海世界博览会的园区建设和园区管理,都有赖其官方组织者--上海世博会事务协调局的协调工作.通过对上海世博会世博局相关工作的探究,可以发现协调与均衡、统筹虽相交但有别,其最终是个运动的、螺旋上升的扬弃过程.     

人本性价值取向与国际关系理论范式

人本性价值取向决定国际理论范式的生成。西方社会主体所崇奉的人性本恶价值取向,决定了在西方国际关系理论中的现实主义处于主体地位的状况。中国国际理论范式的建构也必须以中国传统文化中的人性本善的主体价值取向为基础。     

国际法中健康权的产生、内涵及实施机制

健康权作为二战后兴起的一项重要人权,其发展路径具有从国际法向国内法扩展的特点。"人身的固有尊严"是健康权的正当性基础所在,也决定着健康权的基本内涵。《经济、社会和文化权利国际公约》第12条第1款规定的健康权既是自由权,也是社会权,既指获得卫生保健的权利,也包括获得构成健康基础条件的权利;第12条第2款规定只是列举了公约起草者认为特别重要的四项义务,而非缔约国的全部义务。缔约国义务的性质和范围必须结合公约第2条规定的一般义务条款加以判定。健康权的实施机制包括缔约国报告机制、书面申诉机制,以及调查报告机制三种,不同机制对缔约国的约束力不同,综合运用多种机制确保健康权的有效实施是今后的发展趋势。     

《苏日中立条约》与战时国民外交

1941年,中日战争僵持之际,苏、日两国于4月13日签订了<苏日中立条约>.条约的签订,犹如一石激起千层浪,引起了国际社会的广泛关注.中国民众也没有置之度外,纷纷通过报纸、杂志等媒体表达自己的意见,在民众舆论的配合下,中国政府经过交涉,终于弄清了苏联签约的真正意图,明确了以后的外交方向.     

苏联战俘待遇政策研究（1941～1956）

苏联在二战中遭受了巨大的人员和物质损失,工农业生产均遭到严重破坏,人民生活水平急剧下降,死亡率和发病率明显增高。苏联国内的经济状况严重影响了战俘的待遇水平,在1947年之前,战俘的食品供给标准一直偏低,居住条件相对拥挤,发病率和死亡率一直偏高。但是,苏联政府较为重视战俘的待遇状况,为改善战俘的待遇状况采取了一系列措施,...     

证券虚假陈述民事责任性质之界定

虚假陈述是一种典型的证券欺诈行为,历来成为各国证券法规制的重点。我国2005年修改的《证券法》明确规定了虚假陈述的民事责任,但未明确责任的性质。本文从虚假陈述民事责任性质三种学说的评析入手,结合案例分析了我国实践中存在的问题,并提出了相应的解决办法。     

Views on workplace culture and climate: through the lens of retention and Title IV-E participation

ABSTRACT

Retention of public child welfare (PCW) workers is the focus of much scholarly research. Examinations of the topic have ranged from assessments of workers’ background to job factors and attitudinal components about the workplace. Unlike most studies, the present study uses agency administrative data on retention. In it, 502 PCW workers responded to a point-in-time survey covering a wide range of topics including job satisfaction, commitment to child welfare, perceptions of culture and climate, Title IV-E status, and demographic variables. While Title IV-Es were more likely to leave the agency, several significant interactions between Title IV-E and retention status showed that Title IV-Es who left the agency had significantly lower supervisor satisfaction and influence than Title IV-Es who stayed; and lower efficacy scores than non-Title IV-Es who left. No such differences were found for non-Title IV-E stayers and leavers. Implications for these differences for county agencies and universities are discussed.
