如何正确看待新中国成立后的两个30年

新中国成立后，经历了60余年的风雨历程。这60余年，大致可以分为前30年和后30年两个历史阶段。前30年为社会主义革命和建设时期，后30年为改革开放新时期。究竟怎样看待这两个30年及其相互关系才是正确的，笔者认为：前30年在重大挫折中取得了重大成绩，后30年在改革开放中成绩举世瞩目但问题引入注目，后30年是在前30年基础上发展起来的。它们之间是探索、铺垫与继承、发展的关系。     

党的建设主线的历史考察和理论思考

党的十八大在十七大提出的"把党的执政能力建设和先进性建设作为主线"的基础上,增加了纯洁性建设的内容,强调"牢牢把握加强党的执政能力建设、先进性和纯洁性建设这条主线",从而使党的建设主线内涵更加丰富,更有时代性、针对性。马克思主义执政党的建设,包括党的思想、组织、作风、反腐倡廉、制度等方面的建设,但主线是执政能力建设、先进性和纯洁性建设。党的建设的主线,既是党自身建设的重点,又对其他各方面建设起牵头作用和管总作用。党的建设主线的构成要素,包括执政能力建设、先进性和纯洁性建设。牢牢把握党的建设主线,应当正确认识和把握其中各个要素的科学内涵及其相互之间的内在联系。     

利用残缺赤足足迹推算身高

目的由于主客观条件的影响,犯罪现场中常见的足迹多为不完整的残缺足迹,如何能够有效地利用残缺足迹,对案件破获往往具有至关重要的作用。方法从残缺赤足足迹的反映形态出发,选择足迹中明显、稳定的特征点,确定特征量,通过数理统计分析,建立残缺赤足足迹推算身高的经验公式。结果在4个特征量中,跖前缘突点到跟后缘突点的距离与身高的相关性最好,跖内、外缘突点到跟后缘突点的距离与身高具有一定的相关性。结论根据现场残缺赤足足迹的反映情况,也可以近似推断嫌疑人的身高特点,为侦查提供方向。     

糖尿病肾病五脏相关研究

目的:研究糖尿病肾病患者五脏之间相互影响、相互传变的规律.方法:从广州中医药大学第一附属医院病案室收集62例糖尿病肾病患者的中医证候资料,用stata10.0对各个脏腑证型进行典型相关分析.结果:五脏证型之间两两关系密切,其中肾阳虚证与心气(阳)虚证及心阴(血)虚证相关较大;肾气不固证与脾气(阳)虚证相关较大;肾阴虚证与肝阴(血)虚证相关较大;肾气不固证与肺气虚证相关较大;心气(阳)虚证与脾气(阳)虚证相关较大;寒湿困脾证与痰湿阻肺证相关较大;肝阴(血)虚证与胃阴虚证相关较大;心阴(血)虚证与肝阴(血)虚证相关较大;痰湿阻肺证与肝风内动证相关较大;心气(阳)虚证与痰湿阻肺证相关较大.结论:心、肝、脾、肺、肾两两之间的关系密切.     

品格证据的相关性探讨

品格证据是证据相关性的著名难题。基于“时间的消耗”和“保护陪审团需要”的考虑,英美证据立法确立了品格证据不具有相关性的一般原则。然而有原则便有例外,例如当被告人的品格成为案件构成要素时其相关性并不能被否认。笔者通过演绎推理的方式,以证据相关性一般原理为切入点,探究品格证据相关性这一难题,以为我国品格证据规则的构建提供法理依据。

Experimental and casework validation of ambient temperature corrections in forensic entomology

This paper expands on Archer (J Forensic Sci 49, 2004, 553), examining additional factors affecting ambient temperature correction of weather station data in forensic entomology. Sixteen hypothetical body discovery sites (BDSs) in Victoria and New South Wales (Australia), both in autumn and in summer, were compared to test whether the accuracy of correlation was affected by (i) length of correlation period; (ii) distance between BDS and weather station; and (iii) periodicity of ambient temperature measurements. The accuracy of correlations in data sets from real Victorian and NSW forensic entomology cases was also examined. Correlations increased weather data accuracy in all experiments, but significant differences in accuracy were found only between periodicity treatments. We found that a >5°C difference between average values of body in situ and correlation period weather station data was predictive of correlations that decreased the accuracy of ambient temperatures estimated using correlation. Practitioners should inspect their weather data sets for such differences.     

Comparison of GSR Composition Occurring at Different Locations Around the Firing Position

Abstract: Variations in gunshot residue (GSR) compositions are used in the reconstruction of shooting incidents. In this study, GSR samples taken from seven different locations around and in the firearm were collected and analyzed using scanning electron microscopy/energy dispersive X‐ray analysis. Four different types of ammunition were applied. Very low correlations were found when different ammunition were used. This clearly shows that it is possible to differentiate between ammunition types. When the same ammunition was used, high correlations were found between samples taken from external positions (such as hands of shooter, bullet‐entrance holes) but poor correlation was found between internal samples (such as firearm barrel, cartridge case) and external samples. A high degree of association was found between samples that simulated victim and shooter. These findings clearly demonstrate that GSR comparison studies are meaningful but care needs to be taken when choosing suitable exhibits. External samples (such as hands of shooter, bullet‐entrance holes) are more suitable candidates than internal samples (barrel of the firearm, cartridge case).
