An estimation of the post-mortem interval in human skeletal remains: a radionuclide and trace element approach

Estimation of the post-mortem interval remains a contentious issue, with forensic pathologists often relying upon the recognition of morphological changes.A radionuclide approach has often been suggested in the literature, although limitations have prevented its application, most notably those of diagenesis. Within this pilot study, we show for the first time that there is a correlation between certain radionuclide content and time since death.A larger study is proposed to confirm these findings and possibly provide a calibration against which bones uncovered can be dated.     

Anthropological measurement of lower limb and foot bones using multi-detector computed tomography

Anthropological examination of defleshed bones is the gold standard for osteological measurement in forensic practice. However, multi-detector computed tomography (MDCT) offers the opportunity of three-dimensional imaging of skeletal elements, allowing measurement of bones in any plane without defleshing. We present our experiences of the examination of 15 human lower limbs in different states of decomposition using MDCT. We present our method of imaging and radiological measurement of the bones including sex assessment. The radiological measurements were undertaken by three professional groups--anthropology, radiology, and forensic pathology--both at the site of scanning and at a remote site. The results were compared to anthropological oestological assessment of the defleshed bones. We discuss the limitations of this technique and the potential applications of our observations. We introduce the concept of remote radiological anthropological measurement of bones, so-called tele-anthro-radiology and the role that this could play in providing the facility for standardization of protocols, international peer review and quality assurance schemes.     

Domestic violence and dependency courts: the Greenbook demonstration experience

This field study reports on a cross-site evaluation of dependency courts in communities receiving federal funding to implement the Greenbook initiative, a multisite demonstration for community improvement of coordinated responses to families victimized by domestic violence and child maltreatment. This article focuses on the dependency court, where child maltreatment cases are heard, specifically court participation in collaborative activities and court practice improvements. Findings indicate that perceptions of judicial leadership varied considerably by site. Cross-training appeared to increase over time, particularly with court staff. Collaborative efforts emerged across the Greenbook initiative with regard to the courts, and some innovative practices appeared within Greenbook sites, such as separate case plans for perpetrators and victims of violence in families, reducing the likelihood of controversial failure to protect charges. Results also highlight challenges inherent in changing court practices. Research and practice implications are discussed, focusing on relevance to other communities attempting to work collaboratively with the court system.     

Morphoscopic Trait Expression in “Hispanic” Populations

This study evaluates population variation of eight cranial morphoscopic traits using samples of known southwest Hispanics (n = 72), Guatemalans (n = 106), American Blacks (n = 146), and American Whites (n = 218). We applied the support vector machine (SVM) method to build a prediction model based on a subsample (20%) of the data; the remainder of the data was used as a test sample. The SVM approach effectively differentiated between the four groups with correct classification rates between 72% (Guatemalan group) and 94% (American Black group). However, when the Guatemalan and southwest Hispanic samples were pooled, the same model correctly classified all groups with a higher degree of accuracy (American Black = 96%; American White = 77%; and the pooled Hispanic sample = 91%). This study also identified significant differences between the two Hispanic groups in six of the eight traits using univariate statistical tests. These results speak to the unique population histories of these samples and the current use of the term “Hispanic” within forensic anthropology. Finally, we argue that the SVM can be used as a classification model for ancestry estimation in a forensic context and as a diagnostic tool may broaden the application of morphoscopic trait data for the assessment of ancestry.
