Discrimination of Geographical Origin of Asian Garlic Using Isotopic and Chemical Datasets under Stepwise Principal Component Analysis

Isotopic compositions of δ²H, δ¹⁸O, δ¹³C, and δ¹⁵N and concentrations of 22 trace elements from garlic samples were analyzed and processed with stepwise principal component analysis (PCA) to discriminate garlic's country of origin among Asian regions including South Korea, Vietnam, Taiwan, and China. Results indicate that there is no single trace‐element concentration or isotopic composition that can accomplish the study's purpose and the stepwise PCA approach proposed does allow for discrimination between countries on a regional basis. Sequentially, Step‐1 PCA distinguishes garlic's country of origin among Taiwanese, South Korean, and Vietnamese samples; Step‐2 PCA discriminates Chinese garlic from South Korean garlic; and Step‐3 and Step‐4 PCA, Chinese garlic from Vietnamese garlic. In model tests, countries of origin of all audit samples were correctly discriminated by stepwise PCA. Consequently, this study demonstrates that stepwise PCA as applied is a simple and effective approach to discriminating country of origin among Asian garlics.

组织出卖人体器官罪的构成及认定

近年来,我国有关人体器官买卖的危害行为日益猖獗,严重威胁到广大人民群众的生命健康安全。基于此,刑法修正案（八）第37条明确规定了组织出卖人体器官罪,《刑法》第234条把组织出卖人体器官行为作为刑事犯罪进行打击。文章通过刑法规定的犯罪构成要件,分析了本罪的构成,即本罪的犯罪客体是公民的生命健康权利和国家器官移植医疗管理秩序;犯罪客观方面表现为非法组织他人出卖人体器官的行为;犯罪主体是一般主体;主观方面是故意。因此,司法实践中准确把握本罪与它罪,一罪与数罪的界限非常必要。     

法条竞合该往何处去——以交通肇事罪与过失致人重伤、死亡罪关系为例

法条竞合的研究主要是探寻与想象竞合如何区分,这不仅是理论问题,更是实践课题。遗憾的是,各种学说的混乱,法条竞合适用已然"伤痕累累"。试图建立起法条竞合的城堡,一劳永逸的阻挡想象竞合的侵犯并不可行。归本溯源,法条竞合存在的价值在于维护罪刑法定,要求司法最大程度的尊重立法,限制想象竞合的滥用。因此,不能再拘泥于法条竞合内涵的完善与统一,应当转变视角,追求一种共识即新的路径:基于罪刑法定,构成要件符合的常识性判断是司法的基础,合理怀疑排斥想象竞合的适用。     

网络诽谤罪的客观要件分析

网络诽谤行为一直以来备受关注,其不仅涉及到宪法权利的保护,还涉及到刑法法益的保护。为了准确的打击犯罪,平衡刑法的法益保护机能与自由保障机能,我们首先应当对诽谤、网络诽谤的概念及其外延进行深入研究阐述,其次应对网络诽谤的罪量标准进行定位和具体认定,从而在司法实践中正确地认识和对待网络诽谤罪。     

Determination of Trace Elemental Concentrations in Document Papers for Forensic Comparison Using Inductively Coupled Plasma–Mass Spectrometry

Abstract:  With improvements in manufacturing procedures, comparing physical characteristics of paper samples may not offer sufficient discrimination among different vendors. In this work, the potential to differentiate paper samples based on trace element concentrations was investigated. Paper samples from two different vendors were microwave-digested and trace element concentrations (Mg, Al, Mn, Fe, Sr, Y, Ba, Ce, and Nd) were determined using inductively coupled plasma–mass spectrometry. Differences in concentration were assessed statistically using two-way ANOVA and Tukey's honestly significant differences test. Elemental concentrations were shown to be consistent across a single sheet as well as within a single ream of paper for each vendor. Reams from vendor A were differentiated based on Al and Ba concentration while reams from vendor B were differentiated based on Mg, Mn, and Sr concentrations. Paper was differentiated according to vendor based on significant differences in Ba, Sr, Ce, and Nd concentrations.     

Trace Elemental Analysis of Titanium Dioxide Pigments and Automotive White Paint Fragments for Forensic Examination Using High‐Energy Synchrotron Radiation X‐Ray Fluorescence Spectrometry*

Abstract: High‐energy synchrotron radiation x‐ray fluorescence spectrometry (SR‐XRF) utilizing 116 keV x‐rays was used to characterize titanium dioxide pigments (rutile) and automotive white paint fragments for forensic examination. The technique allowed analysis of K lines of 9 trace elements in 18 titanium dioxide pigments (rutile), and 10 trace elements in finish coat layers of seven automotive white paint fragments. High‐field strength elements (HFSE) were found to strongly reflect the origin of the titanium dioxide (TiO₂) pigments, and could be used as effective parameters for discrimination and classification of the pigments and paint fragments. A pairwise comparison of the finish coat layers of seven automotive white paint fragments was performed. The trace elements in the finish coat layers detected by the high‐energy SR‐XRF were especially effective for identification. By introducing the trace element information of primer and electrocoat layers, all the automotive white paint fragments could be discriminated by this technique.     

涉外继承案件专属管辖考

涉外继承案件是否属于专属管辖范围,从我国《民事诉讼法》的规定看,答案似乎是肯定的,但理论上存有相当大的争议,且实践中,这样的理解也难以变成实际操作。纵观大陆法系德日法等国家立法,将涉外继承案件列入专属管辖范围实属罕见。就国内层面而言,专属管辖可以从法院职能角度和案件特殊性角度进行广义理解,但在国际层面,尤其涉及司法裁决域外承认与执行问题的时候,专属管辖范围的限制就尤为重要;因此,有关不动产物权、法人清算或破产、知识产权诉讼等专属某国法院管辖的观点和做法,日益成为各国普遍认可的事实。从这个角度来看,我们更应审视我国现有规定,从而为涉外继承寻找出合理的法律地位。     

法国犯罪二元论体系的结构性分析

法国各个犯罪二元论体系都是以犯罪(行为)和犯罪人(行为人)为中心建立的体系,从总体上看,有许多相同之处,但是其具体的结构、要素、诸要素的相互关系以及具体的内容、观点却有许多差别,而且任何体系的结构、要素,包括其内容和观点,都是发展、变化的。因此,应当采动态之研究方法,在分别研究法国各个犯罪二元论体系的基础上,把各个犯罪二元论体系作为一个整体,进行全面的、综合的研究,分析其内部的结构和要素,对其变化及发展历史过程进行全面的考察,以把握它们的复杂性、多样性和动态性,寻找其发展变化的规律和趋势,做出总体评价。     

目的犯研究

目的犯是一种没有特定目的便无法构成特定犯罪的一种犯罪形态,是以超过的主观要素为罪责要素的犯罪。在我国《刑法》中既存在法定目的犯的规定,又存在非法定目的犯的规定。目的犯的目的在我国目前通行的犯罪论体系中是作为与故意并列的犯罪主观方面的一个构成要素而存在的。对目的犯的一些特殊犯罪形态的研究,对刑法理论的充实和司法实践的指导均有重要作用。
