权利问题研究与中国当代劳动法观念的更新

正确的观念是正确理论的基础,先进的观念是先进制度的先导。我国传统劳动法学的落后首先是观念的落后,因此,只有注入权利的思维来实现劳动法研究的观念更新,具体要实现从权力本位到权利本位、国家本位到社会本位、利益一致到利益协调的观念转变,才能建立起符合市场经济要求的现代劳动法律制度。     

珠三角汽车产业发展:动因、集群现状及存在问题

基于市场需求、地方政府政策、世界汽车产业转移等多种动因的共同作用,珠三角汽车产业集群形成了集群分布基本特点。虽然珠三角汽车产业发展迅速,在国内汽车产业界中的地位不断提高,但主要问题是本土汽车集团不强,自主开发能力较弱。今后一段时期,应当在解决这些问题上下功夫。     

丹参、黄芪注射液对肝硬化患者肝功能及肝纤维化血清学指标的影响

目的 :探讨丹参注射液和黄芪注射液联合治疗对肝硬化患者肝功能及肝纤维化血清学指标的影响。方法 :将 16 9例肝硬化患者按照随机原则分为 4组 ,对照组静滴甘利欣注射液 ,丹参组、黄芪组、联合组分别给予丹参注射液、黄芪注射液及丹参、黄芪注射液联合治疗 ,均以2 8d为 1个疗程。治疗前后分别检测肝功能丙氨酸转移酶、血浆白蛋白、血清总胆红素等指标和血清肝纤维化指标透明质酸、Ⅲ型前胶原肽、Ⅳ型胶原、层黏蛋白的含量。结果 :丹参组、黄芪组、联合组患者的肝功能改善均优于对照组 (P <0 .0 5 ) ,其中黄芪组和联合组血浆白蛋白明显高于丹参组(P <0 .0 5 ) ;丹参组、黄芪组、联合组患者的血清肝纤维化指标均明显降低 ,与对照组比较 ,差异有显著性 (P <0 .0 1) ,其中联合组降低的程度大于丹参组和黄芪组 (P <0 .0 5 )。结论 :丹参注射液和黄芪注射液对肝硬化患者肝功能及肝纤维化血清学指标均有一定的改善作用 ,联合使用效果更好。

Quantification of Maxillary Dental Arcade Curvature and the Estimation of Biological Ancestry in Forensic Anthropology

Previous studies suggest that palate shape is a useful indicator of biological ancestry in human remains. This study evaluates interobserver error in ancestry estimation using palate shape and explores palate shape variation in Gullah (descendants of West Africans) and Seminole (Indigenous American) population samples using geometric morphometric analysis. Ten participants were asked to ascribe biological ancestry and shape to 28 dental casts based on a classification scheme employed in previous studies. The mean correct classification was 42.0%, indicating that the likelihood of assigning the correct ancestry is very poor and not significantly different from random assignment (p = 0.12). The accuracy analysis based on categorical classification of the casts was complemented by geometric morphometric analysis of nine 3D landmarks reflecting palate shape of 158 casts. Principal component analysis results show no difference between populations regarding palate shape, and cross‐validated discriminant function analysis correctly classified only 62.0% of the specimens. Combined, these results show that previous methods to estimate ancestry are inaccurate and that this inaccuracy is probably due to a lack of palate shape differences between groups, rather than limitation of the analytical method per se. Therefore, we recommend caution should be used when choosing to apply the analysis of palate shape in forensically relevant contexts.     

Automated Classification of Epiphyses in the Distal Radius and Ulna using a Support Vector Machine

The aim of this study was to automatically classify epiphyses in the distal radius and ulna using a support vector machine (SVM) and to examine the accuracy of the epiphyseal growth grades generated by the support vector machine. X‐ray images of distal radii and ulnae were collected from 140 Chinese teenagers aged between 11.0 and 19.0 years. Epiphyseal growth of the two elements was classified into five grades. Features of each element were extracted using a histogram of oriented gradient (HOG), and models were established using support vector classification (SVC). The prediction results and the validity of the models were evaluated with a cross‐validation test and independent test for accuracy (P_A). Our findings suggest that this new technique for epiphyseal classification was successful and that an automated technique using an SVM is reliable and feasible, with a relative high accuracy for the models.     

撞击角度和速度已知条件下的球形弹丸飞行弹道轨迹算法

针对刑侦工作中弹打玻璃类案件的侦破难点,研究一种用于计算球形弹丸抛射击打玻璃案件中弹丸飞行轨迹的算法。本文以弹丸撞击角度和撞击速度为基础参数,在阐明前置基础数据的前提下,将弹打玻璃类案件中的玻璃窗分为垂直于地面及倾斜于地面两类,采用三角函数计算和参数替换的方法,通过对弹丸撞击瞬间的弹道参数设定、弹孔图像在玻璃平面内的二维图像参数设定、相关角度的描述、计算抛物线轨迹与弹道轨迹朝向等一系列步骤,最终,研究出上述两类玻璃窗的弹道轨迹计算方法。研究表明,弹丸弹道飞行轨迹算法可以还原弹丸飞行的轨迹抛物线,作为现场弹道轨迹重建系统的核心算法使用,为开发弹打玻璃类案件的现场弹道轨迹重建系统提供了关键技术。
