Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.     

邓小平对提高党员质量的探索——以中共八大《关于修改党的章程的报告》为文本依据

党员质量问题,是关乎党执政地位巩固和加强执政能力建设的重大问题,是党应对复杂局面和抵御各种风险能力的基础。在党的八大上,邓小平就党员质量问题从提高党员质量必要性、党员质量的标准、党员质量提高的办法等多方面进行了全面深入思考。《关于修改党的章程的报告》凝结了建国以来邓小平提高党员质量的主要思想。     

论公安机关侦查人员法律素养的差异化培养*--以教育培训为侧重

十八届四中全会以来，依法治国成为整个社会发展的主题。刑事侦查领域也提出了侦查法治化的思想，其中加强刑侦队伍正规化建设，提升刑侦队伍执法素养成为一个重要的环节。应该剖析侦查人员法律素养的内涵，立足于侦查人员不同的学习背景，提出差异化培养的思想，并通过有针对性的教育培训等途径提高侦查人员的法律素养，推动侦查工作的法治化进程。     

Estimating Individual Contributions to Complex DNA SNP Mixtures.,

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.     

高频超声检查在周围神经损伤鉴定中的应用价值

目的探讨高频超声检查在周围神经损伤鉴定中应用的价值。方法收集38例锐器伤、钝挫伤、骨折及撞击造成的单侧肢体外伤病例,应用东芝Aplio 500型彩色多普勒超声诊断仪进行高频超声检查,将其特征性表现与30例正常周围神经的高频超声图表现进行对比分析。结果经高频超声检查,确诊38例周围神经损伤中发生于颈部5例、下肢5例,上肢27例(肘部以上3例、以下24例)。损伤类型包括卡压性损伤8例、创伤性神经瘤28例、神经完全断裂2例。特征性表现为:卡压性损伤神经受压处变细,近端神经节段性增粗;创伤性神经瘤与神经干相连的梭形增粗段,增粗段神经外膜的线性强回声中断,内部回声紊乱;神经完全断裂表现为神经外膜强回声线与神经纤维低回声束完全中断,断端两侧均呈梭形瘤样改变。结论高频超声能够明确周围神经损伤类型及发生节段,可为法医学人体损伤程度鉴定提供有价值的参考依据。

发达国家质量监管体系及对我国的启示

我国产品质量法的实施已近二十年了,但我国产品质量状况仍然存在诸多问题。究其原因,与我国目前没有建立起一套完善的质量监管体系不无关系。本文分析了美国、德国和日本等发达国家产品质量监管体制、政策及措施,并以此为启示,提出了构建行政执法、行业自律、舆论监督、群众参与相结合"四位一体"的质量监管体系的立法建议。     

Quality of democracy in unrecognized states: lessons from Northern Cyprus

Scholars have recently debated whether non-recognition is a blessing or a curse for democracy. Some suggest that lack of recognition forces political elites to democratize and acquire internal legitimacy to compensate for the lack of external legitimacy. Others suggest that democratization is used as a strategy by which to acquire international recognition. Still others claim that non-recognition obliges unrecognized states to rely on a patron state which, in turn, hinders the quality of democracy. To contribute to this discussion, we have conducted an in-depth case study. Focusing on democratic quality in Northern Cyprus from 2010 to 2016, it is observed that reliance on a patron state leads to dynamics of tutelage, in turn hindering the quality of democracy.     

变更罪名实证研究

以最高法院示范性案例中的全部变更罪名案例为样本进行实证研究,可以发现其中存在几对实然关系。变更罪名未必都有失公正也不必然体现实体公正,择轻变更未必都有利于被告,合法的变更未必是合理的变更,变更罪名给法律适用带来的不确定性根植于现行法律和法理之中。对其进行法律解释学和犯罪定义学分析,将有助于对变更罪名现象的解读和限制。     

保持共产党员先进性必须突出党员的能力素质建设

在共产党员先进性的构成要素中,政治和思想素质是共产党员先进性的首要问题,是共产党员先进性前提和基础;能力素质和业绩是共产党员先进性诸要素的内在统一,是党员的先进性在实际工作中的体现。保持共产党员先进性,必须重视增强党员践行“三个代表”重要思想、贯彻落实科学发展观的能力和水平,加强共产党员的能力素质建设。
