Evaluation of Suspected Counterfeit Pharmaceutical Tablets Declared to Contain Controlled Substances Using Handheld Raman Spectrometers

This study describes the performance of handheld Raman devices for determining whether suspect pharmaceutical tablets declared to contain controlled substances were consistent with authentic (CWA) or not consistent with authentic (NCWA) tablets using a simple, rapid, field-friendly method capable of being used by nonexperts. Twenty-five authentic products and 84 known NCWA tablets were examined using three “parent” devices for a total of 327 analyses. On average, the parent devices yielded a true pass rate of 100%, a true fail rate of 98.4%, a false pass rate of 1.6%, and a false fail rate of 0%. The methods/libraries were then transferred to 13 identical “daughter” devices, which were used to examine 10 suspect finished dosage forms in duplicate (six known NCWA tablets and four authentic tablets) for a total of 260 measurements. On average, the daughter devices had a true pass rate of 100%, a true fail rate of 95.5%, a false pass rate of 4.5%, and a false fail rate of 0.0%. These data demonstrate that the parent–daughter electronic transfer method was successful, which permits the ability to develop methods in the laboratory that can be seamlessly pushed out to field devices. The methods can then be used to (i) prioritize samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify active ingredients and (ii) help support the interdiction of dangerous tablets at ports of entry, thereby preventing them from reaching the supply chain.     

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.     

论建立我国非法证据排除规则

在刑事诉讼过程中如何取舍和运用刑事非法证据 ,涉及到非法证据的效力问题。两大法系中很多国家建立了非法证据排除规则。我国立法对于非法证据效力的态度不甚明确 ,因此必须完善有关立法 ,制定配套制度 ,建立我国的非法证据排除规则     

Prosecuting Domestic Violence without Victim Participation

This article explores the evidential challenges victim withdrawal presents in domestic violence cases. More specifically it examines innovative measures taken in the United States to overcome problems of proof typically associated with domestic violence prosecutions. These evidentiary initiatives have facilitated a shift towards so–called 'victimless' prosecution in the context of domestic violence which dispenses with victim participation. Drawing upon a 'freedom model' of criminal justice, this article examines whether recent developments in the United States might be emulated as a means of addressing the high rate of attrition in domestic violence cases in England and Wales.     

论弱势群体的社会经济权利

弱势群体是现实社会的客观存在。处于社会弱势地位的人群并不是社会的弃儿,他们同样是社会共同体的平等成员。对弱势群体权利的关注和保障,奠基于基本的社会价值和人性立场。在诸多权利中,对于弱势群体而言,最重要、最具实质性的是社会经济权利。     

证据收集制度

我国在强调当事人举证责任的同时 ,对当事人收集证据的权利缺乏充分、有效的保障。本文在分析两大法系证据收集制度差异及其成因的基础上 ,对我国证据收集程序的运作方式、证据提供义务的范围及违反证据提供义务的制裁措施提出了自己的看法     

火灾发生起数的区间估计和假设检验

在分析火灾发生概率规律性的基础上,可在一定的置信水平上,对火灾发生的起数进行区间估计和假设检验。通过区间估计将未来的火灾形势预测为一个置信区间,通过假设检验可排除随机干扰,确定火灾发生起数的变化规律,这些信息都能为消防规划的制定提供科学的数量依据。     

测谎证据在民事诉讼中的应用

测谎技术是一种现代高科技的产物,我们既不能绝对排斥其在民事审判中的应用,使其游离于民事诉讼程序之外,也不能将其“神化”,将其视为冲破民事诉讼僵局的刹手锏。任何对案件事实的判断都要遵循基本的证明规律,如何在民事诉讼程序中理性地规范地运用测谎技术判断证据,不仅需要立法上进一步完善,也需要我们进一步深入地探索。     

行贿罪案件证据实务剖析

行贿罪案因其固有的“无现场”、“单线联系”和涉案主体的“共利共害”等特征 ,一直是司法实务的难点。行贿犯罪对转型期中国危害的严重性 ,使其成为司法工作的重点。从实证分析的角度 ,对该类案件的证据实务进行剖析 ,将为司法实务提供指导。
