鉴定人角色定位是鉴定人制度中的一个基本问题,它决定着鉴定人的制度设计及鉴定人在诉讼中的权利、义务以及责任的承担。从比较法角度看,英美法系国家的专家证人属于证人,具有党派性的特征。大陆法系国家在鉴定人角色定位问题上有不同的观点。通过梳理发现,这些观点可总结为证据方法说、证据调查说和折衷说三种。在我国,经过民事诉讼立法及相关司法解释的相继出台,鉴定人定位问题的脉络越来越清晰。2019年12月,新《民事证据规定》颁布,鉴定人定位的明晰成为理解、适用新《民事证据规定》鉴定人制度的前提。术语上的届分、内容上的区别是制度完善的基础,"双重属性"下其他专家制度的配套适用也是问题解决的路径。  相似文献

Correctly assessing heart weight can be critical at postmortem examination. The current international guidelines advocate using the short-axis method in dissecting the heart and the heart weighed when the blood is emptied. However, it did not specify at what point the heart should be weighed or how the blood should be emptied. This study compared heart weights at three different time points during the heart examination (immediately after dissecting out of the pericardial sac with blood still in chambers, blood washed/removed from heart chambers without the heart opened, and the heart completely opened, blood emptied, and pad dried). This was to illustrate the variation in measurement and potential errors when the heart is weighed at different time of dissection. The results show that there were statistical and clinical significant differences between the heart weights at each weighing points. We recommend the heart to be completely dissected with any blood and residual washing/rinsing water emptied before being weighed. Although performed in this study, the effect of pad drying the heart on heart weight was not explored and was a limitation in this study.  相似文献

在韩国,对金钱债权1的执行主要分为两个阶段,即对债权的押留阶段和现金化阶段。在金钱债权的押留阶段,韩国主要利用押留命令限制第三债务人对债务人清偿,同时禁止债务人对该债权的处分和领受。在金钱债权的现金化阶段,韩国主要利用推寻命令和转付命令对被押留债权进行现金化,将被押留债权转化为金钱,用所得价款清偿执行债务人的债务。我们需要利用比较研究的方法,研究和借鉴韩国关于金钱债权执行制度的法律规定和相关实务经验,不断完善我国关于债权执行制度的相关规定。  相似文献

When a bullet punctures a surface, it leaves behind a bullet impact, which can be analyzed in order to determine the origin and trajectory path from which a bullet was discharged using many different scientific methods to reconstruct a shooting scene. The purpose of the research was to test the accuracy and repeatability of reconstructing the impact angle of single bullet impacts using the ellipse method. The research was conducted by firing various calibers of ammunition into drywall panels positioned at varying angles of incidence from 88° until ricochet occurred. This was done in order to determine which caliber type and angle of incidence are most accurate and precise for reconstructing a shooting scene. The study examined four caliber types fired into drywall panels, with 5 repeated shots for each of the 11 angles of incidence (n = 220). Furthermore, 31 participants partook in the study to estimate a bullet impact angle of incidence utilizing the ellipse method. The results show that the best performance (accuracy and repeatability) is seen with the measurements of the 0.45 caliber ammunition. When angle of incidences is low (<64°), the performance (accuracy and repeatability) was seen to be better in all caliber ammunitions. Overall, the data provided for single bullet impacts deposited in drywall show that the ellipse method is useful in providing measurements for most crime scene reconstruction purposes and has also demonstrated that results vary depending on the type of ammunition, firearm, and angle of incidence being examined.  相似文献

Recently, digital forensics has become increasingly important as it is used by investigation agencies, corporate, and private sector. To supplement the limitations of evidence capacity and be recognized in court, it is essential to establish an environment that ensures the integrity of the entire process ranging from collecting and analyzing to submitting digital evidence to court. In this study, common elements were extracted by comparing and analyzing ISO/IEC 17025, 27001 standards and Interpol and Council of Europe (CoE) guidelines to derive the necessary components for building a digital forensic laboratory. Subsequently, based on 21 digital forensic experts in the field, Delphi survey and verifications were conducted in three rounds. As a result, 40 components from seven areas were derived. The research results are based on the establishment, operation, management, and authentication of a digital forensics laboratory suitable for the domestic environment, with added credibility through collection of the opinions of 21 experts in the field of digital forensics in Korea. This study can be referred to in establishing digital forensic laboratories in national, public, and private digital forensic organizations as well as for employing as competency measurement criteria in courts to evaluate the reliability of the analysis results.  相似文献

为了检测牛传染性鼻气管炎病毒,本研究建立了牛传染性鼻气管炎病毒SYBR Green I实时荧光定量PCR检测方法。通过设计特异性引物扩增病毒基因,将扩增的目的片段(119 bp)连接到pMD19-T载体中,构建重组质粒。将重组质粒作为阳性标准品,用于SYBR Green I实时荧光定量PCR检测方法的建立。结果显示,特异性引物扩增的目的片段约为119 bp,符合预期的大小,经测序鉴定所扩增的目的片段正确。敏感性结果显示,用该方法检测阳性质粒标准品的最低限度为3.04 X101 copies/mL,是Nano-PCR的10倍。将牛病毒性腹泻病毒、牛呼吸道合胞体病毒、牛副流感病毒3型与牛传染性鼻气管炎病毒进行特异性检测。结果显示,只有牛传染性鼻气管炎病毒被检测到,其他病毒均未有特异性的扩增曲线,表明该方法的特异性良好。批内和批间重复变异系数均小于1%,显示该方法具有良好的重复性。用建立的方法对20份疑似IBRV的临床样品进行检测,并与Nano-PCR检测方法进行对比,结果显示本方法的阳性样晶率高于Nano-PCR检测方法。本研究建立的牛传染性鼻气管炎病毒SYBR Green I实时荧光定量PCR方法特异性好、灵敏度高、重复性好,可用于牛传染性鼻气管炎病毒的检测。  相似文献

ABSTRACT

Using original documents, this paper describes and analyses the case study of one of the productivity bargaining agreements from a leading exponent of productivity bargaining, Mobil’s Coryton Refinery. As well as being important in the UK oil industry these agreements spread throughout the economy. They resulted in major concessions by the unions to relax inter-craft and craft-production trade boundaries and to changes in work methods. These are illustrated in detail and placed in context. Such changes were heralded as ‘new look industrial relations’ and as such were based on a conception of joint regulation. However, other interpretations are possible, and these are then explored and discussed.  相似文献

作为处理事实错误是否阻却故意的理论,具体符合说与法定符合说在打击错误的场合,争论最为激烈。无论是处理结论还是故意理念,具体符合说都更为合理。采用具体符合说并不会导致罪刑不均衡,以错误发生时间的不同为标准可以将对象错误与打击错误区分开。  相似文献

在法律与电子法务专业教学中需注重理论与实践的结合,案例教学法正是最佳的选择。在选择案例方面所选案例应该是原始的、未经任何改变的材料,应具有结论的不确定性。在讲授分析案例时需注意掌握案例分析的一般方法,将法律、法理与案情相结合,注重案例讨论组织的规范性,注重培养学生使用电子网络数据库查找案例的能力。  相似文献
