Visualization of Fingermarks Deposits on Untreated Thermal Paper Exploiting the Near Infrared Luminescence

Thermal paper is widely used as a print medium for different applications but it constitutes a tricky substrate for fingermark visualization. An earlier work (J Forensic Sci 2015; 60 :1034) reported how to visualize fingermarks on untreated thermal paper by illuminating the item with a UV-A light source. In the present paper, the potential of the near infrared (NIR) luminescence has been tested on thermal paper compared to the mentioned method. A controlled study was carried out utilizing eccrine enriched fingermarks. The promising outcomes obtained were further confirmed by performing a pseudo-operational trial. Data clearly showed that the use of the NIR filter gave better results. Finally, preliminary tests suggested a different mechanism of reaction induced by fingermarks with respect to the one behind the thermal printing. Thus, NIR luminescence represents a refinement to the suite of optical examination processes, including the potential to increase the number of marks recovered in a noncontact, nondestructive way.     

How Creating Semiautonomous Agencies Affects Staff Satisfaction

Abstract

Structural reforms such as the creation of autonomous agencies are a widely heralded solution for a multitude of problems in the public sector. These reforms have effects on public employees. This article shows how the structural disaggregation of ministries into autonomous agencies affects staff satisfaction with the organization. The article discusses three cases, where Dutch public organizations were either disaggregated from a ministry or reaggregated to the ministry. These structural reforms constitute a quasiexperimental setting where effects on agency staff and parent ministry staff are compared. In one case, creating the agency led to a decrease in staff satisfaction with the organization as compared to the staff that remained within the ministry. A second case showed that these negative effects linger and can last for more than eight years. An inverse organizational change—reaggregation—caused inverse effects: increasing satisfaction with the organization.     

康拉德《艾米·福斯特》叙事策略探微

本文以西方叙事学为理论依据,从叙述者、叙述聚焦、叙述时间等方面,对现代英国作家约瑟夫·康拉德的短篇小说《艾米·福斯特》进行文本解读,认为康拉德在题材表现、叙述手法、人物刻画、道德指向等方面都独具特色,其创作推动了英国小说从传统走向现代.     

案例指导制度的法律方法研究

目前案例指导制度在我国已基本建立,但在适用过程中还存在与司法实践需求相脱节、文义解释方法过盛、法律论证不充分等问题。因此,应关注和提升法官的裁判说理能力、协调运用多种解释方法、权衡各方利弊等方法来逐步化解案例指导制度的适用难题,以推动和谐统一司法适用局面的早日实现。     

基于12s rRNA的犀牛角制品DNA条形码鉴定分析

目的通过对几种涉案犀牛角制品的12s rRNA条形码序列比对分析,探析12s rRNA在犀牛角制品种属鉴定中的应用可行性。方法以3个案件中的涉案犀牛角制品为材料,采用改良的基因组DNA提取方法,PCR扩增DNA条形码片段12s rRNA。结果通过序列比对与分析,表明12s rRNA可将涉案犀牛角制品鉴定到种的水平。结论 DNA条形码12s rRNA可以作为一个新手段对形态上无法鉴别的犀牛角制品进行准确的种属鉴定,为案件的定性与量刑提供可靠的依据。     

17个Y-STR基因座遗传结构及用于姓氏推断的价值

目的调查我国10个姓氏群体Y-STR的遗传结构,探讨其用于鉴定的价值。方法采用AB Y-Filer荧光检测试剂盒,选取我国占人口数量最多的10个姓氏(李、王、张、刘、陈、杨、赵、黄、周、吴),每个姓氏100名汉族男性个体,采用Y-Filer荧光检测试剂盒,检测17个Y-STR基因座的等位基因频率分布和单倍型多样性,计算其遗传距离并比较群体间差异。结果 10个姓氏间单倍型多样性与总的群体单倍型多样性无显著差异,姓氏间与姓氏内的单倍型随机匹配概率差异很小。分析共祖系数Fst以及Reynold’s遗传距离,10个姓氏间任意两个姓氏群体对应17个Y-STR的Fst值均小于0.01。结论中国汉族10个主要姓氏在大的范围内Y-STR不表现出姓氏特异性,不能用Y-STR进行姓氏推断。

PCR-RFLP在mtDNA多态性分析中的应用

目的探讨PCR-RFLP法在mtDNA多态性分析中的应用价值。方法应用限制酶RsaI和MnlI消化mtDNA D-LOOP区（HVI16106～16297）PCR扩增产物,聚丙烯凝胶电泳进行RFLP分型,对不同PCR-RFLP分型扩增产物进行测序,并对150例辽宁汉族随机个体及30例真三联家系血样进行检验。结果在150例随机个体中,RsaI和MnlI酶切分别发现3和8种表型,DNA测序结果和PAGE分型结果一致,GD值分别为0.107,0.670。联合两种酶切,发现12种表型,GD值为0.708。在30个家系中,母子的RFLP带型完全相同。结论 PCR-RFLP法适合在基层实验室mtDNA分析中应用。     

我国专利侵权损害赔偿额计算方法适用论要

我国专利侵权损害赔偿额计算方法的规定经过了一个变化发展的过程,《专利法》第65条规定了四种损害赔偿额的计算方法。实际损失的确定可采取权利产品销量下降计算法、成本增加计算法、价格腐蚀计算法,侵权所得以侵权产品在市场上销售的总数与每件侵权产品的营业利润或者销售利润之积得出,许可使用费可按固定许可费确定法、惯例确定法、虚拟自愿协商法、分析法计算,适用法定赔偿时应考虑多种因素。
