A Rapid and Efficient Method for Evaluation of Suspect Testimony: Palynological Scanning

A rapid method for evaluating suspect testimony is valuable at any stage in an inquiry and can result in a change of direction in an investigation. Rape cases, in particular, can present problems where a defendant renders DNA analysis redundant by claiming that the claimant consented to have sexual relations. Forensic palynology is valuable in confirming or eliminating locations as being crime scenes, thus checking the testimony of both parties. In contrast to some forensic disciplines, forensic palynology can provide critical information without time-consuming full analysis. Two cases are described where the palynological assemblages from comparator samples of pertinent places were compared with those obtained from clothing of claimants and defendants. The results of rapid microscopical scanning of relevant preparations led to early confessions, thus obviating the need for costly analyses and protracted court proceedings. A third case demonstrates the unbiased nature of this technique where a man, although innocent of any offense, lied about having visited the crime scene for fear of prosecution. This highlights the need for sensitive policing in claims of rape.     

Identification of Missing Norwegian World War II Soldiers,in Karelia Russia

This article presents the multidisciplinary effort in trying to identify the skeletal remains of 100 Norwegian soldiers serving in the German army, killed in Karelia Russia in 1944, from the recovery of the remains through the final identification using DNA. Of the 150 bone samples sent for DNA testing, 93 DNA profiles were obtained relating to 57 unique individuals. The relatives could not be directly contacted as the soldiers were considered as traitors to Norway; therefore, only 45 reference samples, relating to 42 cases of the missing, were donated. DNA matches for 14 soldiers and 12 additional body part re‐associations for these individuals were found. Another 24 bone samples were re‐associated with 16 individuals, but no familial match was found. More than six decades after the end of WWII, DNA analysis can significantly contribute to the identification of the remains.

物证“同一认定“的过程及特征量化分析

物证鉴定的核心问题是“同一认定”理论和物证的特征由定性向定量的转化问题。物证的特征是物证所具有的客观条件和个人的主观条件相结合的产物。个人的知识与实践经验是确定物证特征的主观条件。共性特征和异性特征同属于物证同一认定的评判特征。共性特征决定肯定判断的方向 ,异性特征决定否定判断的方向。物证同一认定具有相对性和矛盾对抗性一面 ,不能把同一认定机械地理解为绝对的“同一”。正确理解和把握同一认定准确率的含义 ,不仅加深了对同一认定理论的正确理解 ,而且树立了唯物辩证法对立统一的世界观 ,对实践工作具有指导意义 ,避免认定工作中存在的盲目性 ,减少错误现象的发生     

利益与道德的关系问题探讨

利益是道德的基础,是整个马克思主义伦理学的基石。科学的道德建设应该以促进生产力发展为核心。社会上的不良道德现象,虽有其存在的复杂原因,但从根本上说是受生产力发展水平制约的。我国的道德建设必须始终以为人民服务为核心,始终把人民的利益放在首位。
