Forensic Application of Analytical Mechanics in Fatal Fall From a Height

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.     

我国大陆与台湾地区搜查要件之分析研究——比较法视野的考量

集侦查行为与强制处分于一身的性质决定了搜查制度的设计必定无法避免控制犯罪与保障人权之间的冲突,而矛盾冲突的解决之道在于谋求调和而非片面牺牲,要在尽可能的范围内谋求并存的方案,并且,在迫不得已时容许最小限度的牺牲。虽然我国宪法已明确昭示“国家尊重和保障人权”,然     

中国汉族与日本群体DYFl55S1基因座的遗传多态性

目的探讨Y染色体DYF155S1基因座的遗传多态性及群体间差异。方法 应用MVR-PCR、荧光显谱及DNA序列分析技术,对来自中国群体(北方汉族,64例)和日本群体(43例)男性个体的DYF155S1基因座进行初步分析。结果107例样本共检出了5种重复序列类型,包括新的命名为6型的重复序列,它是在1型的基础上T22A置换所形成,仅存在于日本群体,可作为民族特征性遗传标记。2群体重复序列的排列方式以3134顺序为主,在中国和日本群体中各占73.44％和67.44％,是黄种人的特点。134顺序在中国群体中占第二位,为17.19％,6134排列占日本群体的16.28％。3’端的4型重复序列的平均数目在日本群体为8.8条,明显低于中国群体的12.5条。结论DYF155S1基因座具有非常高的遗传多态性和明显的群体差异。     

鸡IFN-γ重组鸡痘病毒对鸡传染性腔上囊炎MB43弱毒疫苗免疫鸡免疫应答的影响

将重组鸡痘病毒(rFPV-IFN-γ)与IBD MB43弱毒疫苗联合接种SPF鸡,研究重组鸡IFN-γ对IBD疫苗免疫效果的影响.结果显示,rFPV-IFN-γ和MB43弱毒疫苗联合免疫组(MB43+rFPV-IFN-γ)及rIFN-γ和MB43弱毒疫苗联合免疫组(MB43+rIFN-γ)在免疫后第2周即可检出ELISA抗体,比MB43疫苗单独免疫组早1周.用IBDV Gx株攻击后,MB43+rFPV-IFN-γ组和MB43+rIFN-γ组免疫鸡的脾只有个别淋巴细胞核浓缩、核崩解,少数滤泡萎缩变性坏死;胸腺损伤程度轻于MB43疫苗单独免疫组和非免疫对照组.免疫后1周,3个免疫组外周血CD8+T淋巴细胞含量均显著高于非免疫对照组,CD4+T淋巴细胞含量变化不明显;攻毒后第2周,3个疫苗免疫组CD4+、CD8+T淋巴细胞含量均显著升高,各组之间CD4+、CD8+T淋巴细胞含量无明显差异.证实,rFPV-IFN-γ和rIFN-γ可加强疫苗的细胞免疫和体液免疫应答.     

IDENTIFYING THE PSYCHOLOGICAL FACTORS THAT MEDIATE THE ASSOCIATION BETWEEN PARENTING PRACTICES AND DELINQUENCY*

Past research has largely ignored the developmental changes within the child that account for the association between parenting and risk for delinquency. We used structural equation modeling and data from a longitudinal study of several hundred African‐American families to test the contentions of various theories regarding the sociocognitive and emotional factors that mediate the impact of parental behavior on a youth's risk for delinquency. Our findings largely supported the theories. The impact of monitoring/discipline was indirect through low self‐control and acceptance of deviant norms, whereas the effect of hostility/ rejection was indirect through low self‐control, hostile view of relationships, and acceptance of deviant norms. These two dimensions of parenting were no longer related either to affiliation with deviant peers or to conduct problems once the effects of these psychological characteristics were taken into account; the impact of these parenting practices was completely mediated by these four cognitive/affective variables. Contrary to expectation, however, these psychological factors did not mediate any of the relationship between caretaker involvement in antisocial behavior and child conduct problems.     

传染性喉气管炎病毒王岗株gB基因gC基因和gD基因的真核表达

将传染性喉气管炎病毒(ILTV)王岗(WG)株的gB、gC、gD基因分别克隆到真核表达载体pCAGGS的EcoRⅠ位点,经过酶切、测序分析,筛选鉴定出含有gB、gC、gD基因的重组质粒,分别命名为pCAGGgB、pCAGGgC、pCAGGgD。用质粒纯化试剂盒对重组质粒进行了纯化,将纯化后的质粒转染293T细胞,用间接免疫荧光技术检测了目的蛋白的表达情况。检测结果表明,目的蛋白得到了真实的表达。     

皈依东正教对基辅罗斯文化和艺术的影响

东正教的传入对基辅罗斯产生了巨大而深远的影响。从文化方面说，当时拜占庭帝国是欧洲文化最发达的国家，因此，罗斯受洗后便有机会接触到拜占庭的文化和艺术。这不仅使基辅罗斯的文化教育得到了普及，而且促进了基辅罗斯在文字、绘画、建筑艺术等方面的发展。     

SUPRANATIONAL GOVERNANCE OR NATIONAL BUSINESS‐AS‐USUAL? THE NATIONAL ADMINISTRATION OF EU STRUCTURAL FUNDS IN THE NETHERLANDS AND DENMARK

The partnership principle in EU cohesion policy was introduced in order to involve subnational authorities and interest organizations in policy formulation and implementation. In this article we examine how the member states have reacted to this call for a new way of making public policy. We argue that the multi‐level governance literature and the critics of the multi‐level governance framework have not examined implementation structures properly, but have focused on regional influence. We conduct a comparative analysis of the Dutch and Danish implementations of the European Social Fund and the European Regional Development Fund. Our findings show that when examining implementation structures it becomes clear that member states are in full control of the re‐allocation of EU funds. They show that Denmark and The Netherlands have been able to absorb EU cohesion policy within already existing national implementation structures of labour market policies and regional development. One central theoretical implication of our study is that the focus of studies of any fundamental re‐allocation of power resources in cohesion studies should comprise the entire network of implementation rather than the strategies of its individual component actors.     

税收执法不严的法律经济分析

税收流失问题是我国乃至世界上许多国家都存在的现象,税收执法不严是其成因之一。从法律经济学的角度对税收执法不严进行相应的分析可以进行更有效地防范。征税主体主观执法不严与其客观执法不严都有不同的成因,对此所采取的对策也应区别对待。
