Assessment of Maceration Techniques Used to Remove Soft Tissue from Bone in Cut Mark Analysis 下载免费PDF全文
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 The previously unpublished microwave method fared best for bone and cut mark preservation.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. 相似文献

This paper describes a pilot program in the use of high school near dropouts as tutors for young children. The work is set in the context of adolescent developmental tasks and draws its rationale from the general human tendency to reach mastery by turning passivity into activity. We ask whether adolescents who have experienced a decade of school failure and misery might use the opportunity for a new form of more active contact with the schools to master old failures. We reasoned that the very area of failure, where these adolescents show apparent uninterest through truancy and minimal work, must be a highly emotionally charged one (albeit negatively) precisely because it is an area of failure. After describing the setting and the rationale, we analyze the experience for several tutors from the point of view of their relationship to (1) the tutees, (2) the tutor-supervisor, (3) the group of adolescent tutors, and (4) the social system of the elementary school.Received Ph.D. from Department of Social Relations, Harvard University, 1956.

In forensic image processing, it is often important to be able to separate a feature from an interfering background or foreground, or to demonstrate colors within an image to be different from each other. In this study, a color deconvolution algorithm that could accomplish this task is described, and it is applied to color separation problems in document and fingerprint examination. Subtle color differences (sometimes invisible to the naked eye) are found to be sufficient, which is demonstrated successfully for several cases where color differences were shown to exist, or where colors were removed from the foreground or background. The software is available for free in the form of an Adobe Photoshop-compatible plug-in. 相似文献

The issues of violence and trauma over the past 20 years have generated a significant amount of research. However, the development of each field has remained, for the most part, exclusive from the other. Therefore, the goal of this article is to address this shortcoming within the literature by responding to three important questions: (a) What is the most important thing we have learned about violence and trauma in the past 20 years? (b) What is the most important thing we need to learn in the next 10 years? and (c) What is the most promising methodological innovation in the past 20 years for the study or treatment of trauma or interpersonal violence? This article concludes that by increasing the discourse between the two fields, both research fields may be better able to develop conceptually, methodologically, and empirically. 相似文献

Guastaferro WP 《International journal of offender therapy and comparative criminology》2012,56(5):769-789
More than 2,000 drug courts in the United States provide supervision and substance-abuse treatment to thousands of offenders. Yet the treatment continuum from assessment to aftercare is underexplored. The effectiveness of the Level of Service Inventory-Revised (LSI-R) as a risk assessment tool is well established. However, fewer studies have considered its use in guiding treatment strategies. In using the LSI-R, the drug court program relied on the structured interview protocol (not the risk classification scores) to identify criminogenic needs that then helped determine placement in a high- or low-needs treatment track. To evaluate the effectiveness of these treatment placement decisions, this research used the LSI-R scores to examine individual and group differences (N = 182). Significant and substantive differences at the individual and group levels were found thus providing empirical support for using the LSI-R as a link between assessment and treatment. Implications for developing standards and practice protocols for drug courts are discussed. 相似文献
