个人解雇保护立法实践的国际比较：回应与建设

在个人解雇保护制度的基本要素中,我国在解雇理由、解雇费、不公平解雇赔偿金、不公平解雇主张的时效和复职程度等五个方面的立法规制强度高于国际平均水平;在解雇通知期、解雇程序、通知期开始前的延迟时间三个方面的立法规制强度低于国际平均水平。但综合来看,我国解雇理由虚严实宽,在解雇灵活性和解雇成本方面呈现出复杂扭曲的特点,尤其是定期劳动合同的解雇保护制度大幅降低了我国解雇保护的水平。借鉴国际立法例,根据我国的国情,可以在劳资双方都可接受的限度内,循降低解雇行为灵活性、改变解雇经济成本结构的思路提高解雇保护严格度,并做若干具体制度之改进。     

92式手枪射入口形态特征与射击距离的关系

目的研究手枪射入口形态特征与射击距离的关系,为射击距离的推断提供依据。方法选择92式手枪,在带皮的猪肉上覆盖白色棉布,设计了0m,0.1m,0.2m,0.5m1.0m,1.5m,3.0m,5.0m,10m,15.0m,20.0m,25.0m共12个射击距离,对白棉布和肉皮上的弹孔进行拍照,对比研究不同射击距离的射入口形态特征,并利用Autocad软件对射入口的面积进行计算。结果白棉布和肉皮上射入口的形态特征与射击距离有一定的相关性。结论根据射入口的形态特征,能够对射击距离进行推断,对涉枪案件中射击距离的判断有参考价值。     

Risking Regulation,Regulating Risk: Lessons from the Transatlantic Biotech Dispute

Debates over the future of new technologies frequently implicate governmental policies and regulation, the purpose of which has traditionally been to mitigate the dangers of new technologies through promotion of conditions of safe use. It is increasingly recognized, however, that regulation is predicated on a particular conception of the nature of risk which may or may not correspond to the views and beliefs held by society. Here I explore three broadly related questions in the context of the debates around agricultural biotechnology. First, what are the implications of varying conceptions of risk for regulatory policy in the United States and in the European Union? Second, what are the implications of differing conceptions of risk and resulting regulatory policy for agricultural trade relations between the two giants of international trade? And finally, what lessons might we draw from contemporary disputes over agricultural biotechnology?     

公安干警手枪射击比赛选手的心理调节与控制

公安干警手枪射击比赛选手要想在短时间内取得较好的成绩,除了应提高技战术水平和身体素质以外,还应具备良好的意志品质和心理状态。本文从培养公安干警注意力品质、意志品质及调节公安干警心理状态三个方面探讨公安干警手枪射击时的心理调节与控制问题,提出具体的训练方法,对公安干警手枪射击教学具有现实的指导意义。     

我国转基因产品标识问题研究

在规范转基因产品的众多法律制度当中,转基因产品是否进行标识,既体现着一国对转基因产品的态度,也影响着一国政治经济的发展。总结各国学者对转基因产品标识的研究,着眼于保障国家粮食供应和粮食安全,尽可能将转基因产品的风险最小化。设计适合我国国情的转基因产品标识制度,并用法律制度对其进行规制,成为我国目前面临的重要问题之一。     

3种甲醛固定组织DNA提取方法的比较

目的对不同方法提取甲醛固定组织中DNA的效果进行比较,寻找一种操作简便、经济实用、质量较高的DNA提取方法。方法取甲醛固定的心肌组织14份,分别以改良酚-氯仿法,改良Trizol法,试剂盒法提取DNA,进行紫外分光光度计测定OD260/OD280值后,经PCR扩增,琼脂糖凝胶电泳分析确定提取的DNA质量。结果改良酚-氯仿法,改良Trizol法,试剂盒法OD260/OD280比值分别为1.841 5±0.380 4、1.370 5±0.336 7、0.831 6±0.175 0。两两比较均有显著性差异(P<0.05)。3种不同方法提取DNA含量分别为0.943 8±0.530 1、0.707 5±0.423 6、0.342 8±0.182 5。PCR扩增后琼脂糖凝胶电泳显示以改良酚-氯仿法所提DNA的谱带清晰度好于其它两种方法。结论改良酚-氯仿法简便有效,所用试剂价格低廉,是一种经济实用的甲醛固定组织DNA提取方法。     

对"黑社会组织"概念的词义分析与实证考究

黑社会组织是指由众多成员组成,有严密的组织性和组织亚文化,使用暴力、威胁手段,或以其为后盾,控制一定的社会区域或行业,向权力部门渗透并建立保护伞,以牟取经济利益为最终目的的半隐蔽的社会群体.黑社会组织具有成员众多性、暴力性、组织严密性、垄断性、获取经济利益目的性、半隐蔽性、形成自己的亚文化、建立保护伞等特性.凭借权力庇护和组织暴力,在一定社会区域或行业牟取经济利益是黑社会组织的本质特征.     

QSZ92式9mm手枪射击弹壳击针痕迹次种类特征的研究

目的研究QSZ92式9mm手枪击针在生产加工过程中潜在的次种类特征,以区别于个体特征。方法用超景深体式显微镜对特定工序连续生产加工的10件QSZ92式9mm手枪击针的射击痕迹进行观察比对。结果不同击针形成的击针痕迹痕底特征具有特定性,而痕壁特征中的同心圆状或圆弧状加工痕迹具有相似性,属于次种类特征。结论同一认定过程中不能将击针痕迹中的同心圆状或圆弧状加工痕迹作为个体特征使用。     

A novel method for the analysis of discharged smokeless powder residues

A novel method for the estimation of intermediate-long firing distance range is proposed. The method is based on the characterization and chemical analysis of the smokeless powder particles on the target. An adhesive lifter is applied to collect the suspected gunshot residues (GSRs) from the surface of an object, and a Modified Griess Test (MGT) is carried out after alkaline hydrolysis on the adhesive lifter. Visualized particles are removed from the adhesive lifter under a microscope. Two systems are used for the analysis of organic discharge residues from the smokeless powder: (1) gas chromatography/thermal energy analysis (GC/TEA) for the analysis of nitroglycerine (NG) and 2,4-dinitrotoluene (2,4-DNT), (2) gas chromatography/mass spectrometry (GC/MS) for the identification of organic components such as DNT, NG, and some stabilizers. By using this procedure and confirming that the suspected particles are indeed GSR, one can estimate the intermediate-long firing distance of c. 0.75-3 m in the presence of very few particles and provide information for the classification of ammunition type in casework.
