计算机笔迹鉴定技术的文检视角分析

科学技术的发展使计算机笔迹鉴定技术日渐成熟并且逐步走入了文件检验实务领域。从文件检验尤其是笔迹鉴定业务的视角出发,业内人士需要对计算机笔迹鉴定系统的设计原理、算法思想、发展方向有整体的了解。伪装书写等因素使“能全面、准确识别特征字符的最优算法”难以开发出来,这与综合评断的复杂性共同决定了此类系统应为鉴定人员快速、准确地作出结论而提供辅助作用。构建笔迹鉴定的客观标准,在人工检验中充分发挥计算机高效、客观的自动初筛功能,应成为笔迹鉴定的发展方向。     

浅析大学生博客写作动机与高校写作教学

博客作为一种互联网文化现象正在迅速崛起,引起了敏锐的教育界人士对其教育应用的探索;博客的写作动机与写作行为可以相互激发、相互加强,生理的内驱力、社会的内驱力、理智的诱因、情绪的诱因和社会的诱因激活了大学生多种多样的写作动机;利用大学生的博客写作动机实施写作教学,是高校写作教学的一条有效途径。     

对文件绝对形成时间的综合检验

在理论上,文件一定能反映出某种时闻信息,这为人们鉴定文件形成时间提供了可能性。文检工作者通常采用理化方法进行文件形成时间的检验,但该方法常受制于纸质、色料、保管条件等,因此在实践中并非每份文件都能够检验出形成时间。对于不具备理化检验条件的案件,应该分析文件时间特征,进行综合检验,以确定文件的绝对形成时间。     

系统鉴定方法在朱墨时序鉴定中的应用

朱墨时序鉴定是通过对印字交叉部位的检验,得出的印字先后顺序的判断。朱墨时序鉴定是文件鉴定的重要组成部分,它往往是判定文件物证真实性的重要依据之一。任何文件物证都是一个由多个要素组成的文件系统。通过介绍系统鉴定方法的原理、方法,以鉴定实践说明其在朱墨时序鉴定中的三种作用,同时也强调各种检验方法的综合运用。提倡在朱墨时序鉴定中,应运用系统鉴定方法,更加准确的把握印字交叉部位的表观特征,从而提高朱墨时序鉴定的准确性。     

Mixed Rules,Different Roles? An Analysis of the Typical Pathways into the Bundestag and of MPs' Parliamentary Behaviour

Does the German mixed electoral system produce two types of representatives – MPs elected in the district who aim primarily to represent the interests of their constituencies and list MPs who are primarily loyal to their party or seek to serve ‘functional’ interest groups? The paper addresses this controversial question in two steps. It first uses sequence analysis in order to discover empirically just how prominent the exclusive ‘path into the Bundestag’ actually was by way of either the party list or the electoral district. The empirical basis is a data set covering all 3581 members of parliament from 1949 to 2009. Secondly, after having identified MPs with clear district or list careers, the paper replicates a study on committee membership asking whether district MPs sat more often in committees that are of relevance for their districts while list MPs more often sit in so-called ‘policy’ committees. The paper finds no evidence for a clear ‘mandate divide’ between MPs elected in a district and those numerous MPs entering parliament via the party list but also contesting a district.

The Writing Lesson: Imaginary Inscriptions in Cultural Encounters

Abstract

This article takes a moment of intercultural exchange, first reported as "The Writing Lesson" by Claude Lévi-Strauss in Tristes Tropiques and later explored by Jacques Derrida in Of Grammatology, as the occasion for further reflection on the role played by the aesthetic in what it terms intercultural transference. Transference occurs whenever unconscious desires, fantasies or patterns of being and relating are enacted in an interpersonal or intercultural encounter, including the indirect encounters between literary or artistic objects and their recipients. It emerges as a largely unconscious operation designed to bridge, close, fill or deny the inevitable gaps in knowing another person or another culture, and to manage the affects such gaps bring forth. Intercultural transference provides a framework to read "The Writing Lesson" differently and suggests a theoretical model able to account for the complex performances of intercultural transference that enter any exchange or translation between cultures.     

State writing,subversion and citizenship in Southern Rhodesia’s state of emergency, 1959–1960

This article takes a moment of political upheaval – Southern Rhodesia’s 1959 State of Emergency – to explore the uses of writing in the remaking of state authority and citizenship. The 1950s had produced a powerful bureaucratic state, a shaky attempt at multi-racial “partnership,” and African aspirations to a citizenship able to encompass equality, rights and self-determination. The Emergency brought the tensions in these modes of government and citizenship to the fore. The article explores the working out of these tensions in two instances: the bureaucratic attempt to manage political detainees, and the police evidence used to substantiate charges of subversion on the part of nationalists in court. The article traces the limits of the state’s “lawfare” and the means by which detainees and nationalists developed new understandings of citizenship as aspirational imaginary, legal condition and practical tool, through the written word.     

A Set of Handwriting Features for Use in Automated Writer Identification,

A writer's biometric identity can be characterized through the distribution of physical feature measurements (“writer's profile”); a graph‐based system that facilitates the quantification of these features is described. To accomplish this quantification, handwriting is segmented into basic graphical forms (“graphemes”), which are “skeletonized” to yield the graphical topology of the handwritten segment. The graph‐based matching algorithm compares the graphemes first by their graphical topology and then by their geometric features. Graphs derived from known writers can be compared against graphs extracted from unknown writings. The process is computationally intensive and relies heavily upon statistical pattern recognition algorithms. This article focuses on the quantification of these physical features and the construction of the associated pattern recognition methods for using the features to discriminate among writers. The graph‐based system described in this article has been implemented in a highly accurate and approximately language‐independent biometric recognition system of writers of cursive documents.     

牛病毒性腹泻病毒基因1型全基因组的测序分析

以我国新疆地区分离的1株牛源牛病毒性腹泻病毒基因1型毒株为研究对象,参照GenBank中的牛病毒性腹泻病毒1型基因组全序列,根据保守序列设计6对重叠引物,通过RT-PCR扩增出该毒株不同的cDNA片段,分别克隆到pMD19-T载体,转化受体菌JM109,挑取阳性克隆进行PCR、酶切鉴定及测序分析,为了解该毒株的遗传变异及基因结构与生物功能的关系,为开发牛病毒性腹泻病毒新型疫苗奠定基础。测序结果表明,该病毒全基因序列核苷酸为12 302nt(GenBank登录号:JN704144),该病毒基因组具有一个11 694nt开放阅读框编码的多聚蛋白,5′-UTR长382nt,3′-UTR长224nt,BVDV1-3156的全基因组序列分析发现该毒株为BVDV1b亚型。Blast比对分析显示,该毒株与VEDEVAC株的相似性最高,为90.9%。该毒株与BVDV1型其他毒株的全基因组序列具有较大的差异。
