A comparative research of two lifting methods: electrostatic lifter and gelatin lifter

Two-dimensional dust shoeprints are often of very high resolution and contain unique features. Lifting these prints in the most effective method may contribute much to preserving these fine details. A research was conducted by experts from Israel and Switzerland to compare gelatin lifters and electrostatic lifters for lifting shoeprints. Several substrates were chosen, and on each material a set of dry dust shoeprints was made. A set of wet prints was made on paper as well. The shoeprints were approximately of the same quality, and the only variable was the nature of the material. On substrates indifferent to the method used, the preferable sequence was tested. Gelatin lifter was superior on most substrates and for wet prints. The superior sequence for using both methods is electrostatic lifting followed by gelatin lifter.     

Identification of group affinity from cross-sectional contours of the human midfacial skeleton using digital morphometrics and 3D laser scanning technology

Identifying group affinity from human crania is a long-standing problem in forensic and physical anthropology. Many craniofacial differences used in forensic skeletal identification are difficult to quantify, although certain measurements of the midfacial skeleton have shown high predictive value for group classifications. This study presents a new method for analyzing midfacial shape variation between different geographic groups. Three-dimensional laser scan models of 90 crania from three populations were used to obtain cross-sectional midfacial contours defined by three standard craniometric landmarks. Elliptic Fourier transforms of the contours were used to extract Fourier coefficients for statistical analysis. After cross-validation, discriminant functions based on the Fourier coefficients provided an average of 86% correct classifications for crania from the three groups. The high rate of accuracy of this method indicates its usefulness for identifying group affinities among human skeletal remains and demonstrates the advantages of digital 3D model-based analysis in forensic research.     

Assessment of approximate likelihood ratios from continuous distributions: a case study of digital camera identification

A reported likelihood ratio for the value of evidence is very often a point estimate based on various types of reference data. When presented in court, such frequentist likelihood ratio gets a higher scientific value if it is accompanied by an error bound. This becomes particularly important when the magnitude of the likelihood ratio is modest and thus is giving less support for the forwarded proposition. Here, we investigate methods for error bound estimation for the specific case of digital camera identification. The underlying probability distributions are continuous and previously proposed models for those are used, but the derived methodology is otherwise general. Both asymptotic and resampling distributions are applied in combination with different types of point estimators. The results show that resampling is preferable for assessment based on asymptotic distributions. Further, assessment of parametric estimators is superior to evaluation of kernel estimators when background data are limited.     

高职院校图书馆数字信息资源建设研究

文化遗产数字化成果私权保护:价值、成效及制度调适

《知识产权强国建设纲要》和党的十九大报告中明确指出要加强非物质文化遗产的搜集整理和转化利用,推动中华优秀传统文化创造性转化、创新性发展,文化遗产传承和发展由此迎来自我更新的契机.我国对于文化遗产的相关法律保护目前以公法为主,私法保护取得了一定的实践成效,但其法律制度尚不完善.而数字环境下文化遗产及其元素的利用较强地依赖...     

浅论数码照相提取现场粉尘足迹

选用佳能G5照相机进行数码照相有利于提取犯罪现场粉尘足迹。根据分析实验拍照效果后发现,对拍照平面粉尘足迹影响较大的是配光方法。在实践中,拍照平面粉尘足迹配光方法主要有定向反射用光法、暗视场照明法和掠入射照明法。在拍照粉尘足迹过程中,应当注意使用传统的手动曝光方法和运用不同的配光方式,理顺配光与主客体之间的关系,尽可能使用掠入射照明法进行配光。     

ACTA关于“数字环境下知识产权执法”规则评析

ACTA虽然是知识产权执法的最新国际标准,但是,其关于数字环境下的知识产权执法规则与WCT以及WPPT的要求并没有实质差异。我国现行知识产权法的有关规定虽然与ACTA之间有一定的差异,但并不存在深刻的矛盾,甚至在大多数方面已经符合ACTA的标准。因此,是否接受ACTA规则可以作为我国政府在知识产权国际谈判中的筹码。同时,ACTA提供了一个全面审视、评估、反思和构建我国知识产权执法制度的机会。     

Effect of chloride ion concentration on the galvanic corrosion of α phase brass by eccrine sweat

Inductively coupled plasma mass spectrometry measurement of the relative concentration of sodium, chloride, calcium, and potassium ions in eccrine sweat deposits from 40 donors revealed positive correlations between chloride and sodium (ρ = 0.684, p < 0.01) and chloride and calcium ions (ρ = 0.91, p < 0.01). Correlations between ion concentration and the corrosion of α phase brass by the donated sweat were investigated by visual grading of the degree of corrosion, by measuring the copper/zinc ratio using energy-dispersive X-ray spectroscopy, and from a measurement of the potential difference between corroded and uncorroded brass when a large potential was applied to the uncorroded brass. An increasing copper/zinc ratio (indicative of dezincification) was found to correlate positively to both chloride ion concentration and visual grading of corrosion, while visual grading gave correlations with potential difference measurements that were indicative of the preferential surface oxidation of zinc rather than copper.     

关于提高公安院校图书馆数字资源利用率的探析

公安院校图书馆需要发展数字资源馆藏,但现有条件使得数字资源建设难以形成规模,造成馆藏中现有的数字资源缺乏独到的资源优势,难以吸引现有的用户群体,利用率较低,需要从读者培养服务、数字馆藏建设、数字资源服务手段等方面加以调整,以提高馆藏数字资源的利用率。
