减少关押看管：社区矫正的贡献

关押已经宣告为有罪或者正在等待审判的人员,是一个具有理论与实践价值的问题。本研究表明在一个关押率低的州,保释金支持项目能够分配到足够的资源,并以一种高姿态对待那些主要的决定者,这说明在司法系统审讯前和宣判阶段,对社区矫正的投资能够降低关押的财政和社会成本,社区矫正项目同时还有能力提升犯罪司法系统的有效性。但是,一些政治性因素,诸如“严厉打击犯罪”舆论的普及,将会限制澳大利亚人在自己的权限范围内采用社区为本的矫正方案。     

Assessment of Maceration Techniques Used to Remove Soft Tissue from Bone in Cut Mark Analysis

Maceration techniques employed in forensics must be effective without compromising the bone's integrity and morphology, and prevent destruction of evidence. Techniques must also be fast, safe, easily obtainable and inexpensive; not all techniques currently employed are appropriate for forensic use. To evaluate the most suitable approach, seven techniques including current and new methodologies were applied to fresh, fleshed porcine ribs exhibiting cut marks. A sample size of 30 specimens per technique was examined under scanning electron microscopy at the cut mark and the surrounding uncompromised regions; a scoring system of effectiveness was applied. The previously unpublished microwave method fared best for bone and cut mark preservation. Sodium hypochlorite destroyed cut marks, and was deemed unsuitable for forensic analysis. No single technique fulfilled all criteria; however, this study provides a benchmark for forensic anthropologists to select the most appropriate method for their situation, while maintaining the high standards required by forensic science.     

The detection of Y chromosomes in bloodstains--a reevaluation

A method has been described for detecting Y chromosomes in the leukocytes of human bloodstains prepared on a variety of substrates. The factors that influence the proportion of chromosomes exhibiting a Y spot (the Y cell index) in a bloodstain are considered, including the subjective nature of assessment of the Y chromosome fluorescence, the substrate, and the age of bloodstain. In contrast to previous workers no decay in Y cell index with the age of the stain was observed. The results of a blind trial involving stains derived from case work, where from other evidence there was no doubt as to the sex of the donor, are presented. Sixty-five percent of the male bloodstains were correctly identified and no females were wrongly reported as male.
