Quantitative Analysis of the Morphological Changes of the Pubic Symphyseal Face and the Auricular Surface and Implications for Age at Death Estimation 下载免费PDF全文
Chiara Villa Ph.D. Jo Buckberry Ph.D. Cristina Cattaneo M.D. Ph.D. Bruno Frohlich Ph.D. Niels Lynnerup M.D. Ph.D. D. M. Sc. 《Journal of forensic sciences》2015,60(3):556-565
Age estimation methods are often based on the age‐related morphological changes of the auricular surface and the pubic bone. In this study, a mathematical approach to quantify these changes has been tested analyzing the curvature variation on 3D models from CT and laser scans. The sample consisted of the 24 Suchey–Brooks (SB) pubic bone casts, 19 auricular surfaces from the Buckberry and Chamberlain (BC) “recording kit” and 98 pelvic bones from the Terry Collection (Smithsonian Institution). Strong and moderate correlations between phases and curvature were found in SB casts (ρ 0.60–0.93) and BC “recording kit” (ρ 0.47–0.75), moderate and weak correlations in the Terry Collection bones (pubic bones: ρ 0.29–0.51, auricular surfaces: ρ 0.33–0.50) but associated with large individual variability and overlap of curvature values between adjacent decades. The new procedure, requiring no expert judgment from the operator, achieved similar correlations that can be found in the classic methods. 相似文献

The Applicability of the Lamendin Method to Skeletal Remains Buried for a 16-Year Period: A Cautionary Note 下载免费PDF全文
Danilo De Angelis D.D.S. Ph.D. Elia Mele B.Sc. Daniele Gibelli M.D. Ph.D. Vera Merelli M.D. Laura Spagnoli M.D. Cristina Cattaneo M.D. Ph.D. 《Journal of forensic sciences》2015,60(Z1):S177-S181
The Lamendin method is widely reported as one of the most reliable means of age estimation of skeletal remains, but very little is known concerning the influence of burial in soil. This study aimed at verifying the reliability of the Lamendin method on corpses buried for 16 years in a cemetery. The Lamendin and the Prince and Ubelaker methods were applied. In all age groups except the 40- to 49-year–olds, the error was higher in the buried sample. The age-at-death error ranged between 10.7 and 36.8 years for the Lamendin method (vs. the reported 7.3–18.9 years) and 9.5 and 35.7 for the Prince and Ubelaker one (vs. the original 5.2–32.6 years); in all age groups, the error is closer to that found on archeological populations. These results suggest caution in applying the Lamendin method to forensic cases of human remains buried even for a brief period under soil. 相似文献

The aim of this study was to analyze the relevance of callous–unemotional (CU) traits in incarcerated juvenile delinquents. A sample of 160 incarcerated male youths was used. Results showed that youths with high CU traits had an earlier age of crime onset and of trouble with the law, and also had higher levels of conduct disorder. When controlling for age of crime onset, youths with high CU traits showed higher levels of general psychopathic traits and of psychopathy taxon membership as well as lower levels of prosocial behavior, but no differences were found for self-reported delinquency, crime seriousness, impulsivity-conduct problems, and general conduct problems. Also, no significant associations of CU traits with self-reported delinquency and crime seriousness were found when controlling for age of crime onset. Future studies of CU traits should take into account the specific importance of age of onset. 相似文献

This paper explores the role of conferences as “convergence space”: temporary events with lasting material effects. Drawing on three harm reduction conferences occurring between 2011 and 2012, I argue that conferences are both ephemeral fixtures in the landscape of policy activism, and are important nodes through which policy mobilization occurs. Conference spaces provide opportunities for ideas to be shared, produced and advocated. They serve as important sites for the construction of relationships that are required to form and maintain policy advocacy networks and harness political opportunity structures for drug policy reform. 相似文献

The authors are exploring degradation patterns of latent fingermarks over time which can be quantitatively determined in a predictable manner by visual means. Several physical degradation parameters for assessing this hypothesis are evaluated. This article analyzes the parameter “minutiae count” as a function of time. Experiment variables included were secretion type (sebaceous‐rich and eccrine‐rich), substrate (glass and plastic), and exposure to light (dark, shade, and direct light). Depositions were sequentially visualized with Titanium Dioxide powder over a period of 6 months, photographed, and number of minutiae recorded. Results revealed a significant decrease of minutiae for eccrine‐rich marks on glass but insignificant for sebaceous‐rich marks on the same surface. However, significant degradation was observed for both types of secretions on plastic. The authors conclude that the distinctive prevalence of minutiae changes over time indicates with a high degree of certainty the hypothesis is valid and deserves additional exploration. 相似文献

Craniofacial superimposition is a technique potentially useful for the identification of unidentified human remains if a photo of the missing person is available. We have tested the reliability of the 2D‐3D computer‐aided nonautomatic superimposition techniques. Three‐dimension laser scans of five skulls and ten photographs were overlaid with an imaging software. The resulting superimpositions were evaluated using three methods: craniofacial landmarks, morphological features, and a combination of the two. A 3D model of each skull without its mandible was tested for superimposition; we also evaluated whether separating skulls by sex would increase correct identifications. Results show that the landmark method employing the entire skull is the more reliable one (5/5 correct identifications, 40% false positives [FP]), regardless of sex. However, the persistence of a high percentage of FP in all the methods evaluated indicates that these methods are unreliable for positive identification although the landmark‐only method could be useful for exclusion. 相似文献
