Morphometric Comparison of Clavicle Outlines from 3D Bone Scans and 2D Chest Radiographs: A Shortlisting Tool to Assist Radiographic Identification of Human Skeletons

This paper describes a computerized clavicle identification system primarily designed to resolve the identities of unaccounted‐for U.S. soldiers who fought in the Korean War. Elliptical Fourier analysis is used to quantify the clavicle outline shape from skeletons and postero‐anterior antemortem chest radiographs to rank individuals in terms of metric distance. Similar to leading fingerprint identification systems, shortlists of the top matching candidates are extracted for subsequent human visual assessment. Two independent tests of the computerized system using 17 field‐recovered skeletons and 409 chest radiographs demonstrate that true‐positive matches are captured within the top 5% of the sample 75% of the time. These results are outstanding given the eroded state of some field‐recovered skeletons and the faintness of the 1950's photofluorographs. These methods enhance the capability to resolve several hundred cold cases for which little circumstantial information exists and current DNA and dental record technologies cannot be applied.     

Disopyramide and Mianserin Intoxication: A Unique Fatal Case – Review of the Literature

Lethal occurrence is exceptional after disopyramide or mianserin poisoning. A case of intentional lethal intoxication with these drugs was reported, as well as a review of the literature. Pre‐ and postmortem blood concentrations of disopyramide or mianserin were assessed in a woman who died from acute cardiac failure after ingestion. The premortem blood concentration of disopyramide alone was considered lethal, and a toxic premortem concentration of mianserin was observed that may have increased cardiovascular failure induced by disopyramide because the metabolism of both drugs is mediated via cytochrome P450. Moreover, it was shown that the postmortem redistribution of disopyramide was limited, as pre‐ and postmortem concentrations were 48 and 65 mg/L, respectively. As regards mianserin, redistribution was observed after death with pre‐ and portmortem concentrations at 0.23 and 0.79 mg/L, respectively. This case illustrates that if postmortem blood concentration of disopyramide is known, the premortem concentration can be deduced.     

Nord-Mali: les frontières coloniales de l’Azawad

RÉSUMÉ

La revendication en 2012 de l’indépendance de l’Azawad a été strictement limitée au seul Mali et à ses frontières septentrionales, d’origine coloniale. Un “État (pan)touareg” regroupant les populations touarègues (Algérie, Mali, Niger, Burkina-Faso, Libye) n’a pas non plus été revendiqué. Cette situation ne peut s’expliquer sans tenir compte des héritages anciens. La définition des territoires impériaux, et des frontières coloniales, connut un processus très différent de ce que suggère le mythe de la conférence de Berlin. Les logiques à l’?uvre témoignent d’une co-construction des frontières avec les populations locales, ou pour le moins le résultat de stratégies croisées de l’administration coloniale et des pouvoirs africains. Les rébellions récurrentes, et le séparatisme récent, ne peuvent donc avoir comme seule explication les tracés frontaliers. Il faut intégrer dans l’analyse les histoires locales, et surtout la gestion politique et économique des marges par l’administration française puis par les États indépendants.     

Accuracy and reliability in sex determination from skulls: a comparison of Fordisc® 3.0 and the discriminant function analysis

Identification in forensic anthropology and the definition of a biological profile in bioarchaeology are essential to each of those fields and use the same methodologies. Sex, age, stature and ancestry can be conclusive or dispensable, depending on the field. The Fordisc(?) 3.0 computer program was developed to aid in the identification of the sex, stature and ancestry of skeletal remains by exploiting the Forensic Data Bank (FDB) and computing discriminant function analyses (DFAs). Although widely used, this tool has been recently criticised, principally when used to determine ancestry. Two sub-samples of individuals of known sex were drawn from French (n=50) and Thai (n=91) osteological collections and used to assess the reliability of sex determination using Fordisc(?) 3.0 with 12 cranial measurements. Comparisons were made using the whole FDB as well as using select groups, taking into account the posterior and typicality probabilities. The results of Fordisc(?) 3.0 vary between 52.2% and 77.8% depending on the options and groups selected. Tests of published discriminant functions and the computation of specific DFA were performed in order to discuss the applicability of this software and, overall, to question the pertinence of the use of DFA and linear distances in sex determination, in light of the huge cranial morphological variability.     

How Citizens’ Education,Occupation, Personal Economic Expectations and National Identity Interact with One Another to Sway Public Opinion on the EU

Abstract: This article examines the pattern of interactions between education, occupation, personal economic expectations and feelings of national identity and how these interactions affect public support for the EU. Using Eurobarometer data from 1993 to 2006, the results in this paper demonstrate that occupation mediates the relationship between EU support and education. It is also found that the sway of citizens’ personal financial expectations on EU support is not conditioned by education and occupation. Finally citizens’ personal economic expectations are not found to condition the relationship between EU support and feelings of national identity. In the light of these findings the paper draws implications.     

Considerations on the ASTM Standards 1789‐04 and 1422‐05 on the Forensic Examination of Ink

Abstract: The ASTM standards on Writing Ink Identification (ASTM 1789‐04) and on Writing Ink Comparison (ASTM 1422‐05) are the most up‐to‐date guidelines that have been published on the forensic analysis of ink. The aim of these documents is to cover most aspects of the forensic analysis of ink evidence, from the analysis of ink samples, the comparison of the analytical profile of these samples (with the aim to differentiate them or not), through to the interpretation of the result of the examination of these samples in a forensic context. Significant evolutions in the technology available to forensic scientists, in the quality assurance requirements brought onto them, and in the understanding of frameworks to interpret forensic evidence have been made in recent years. This article reviews the two standards in the light of these evolutions and proposes some practical improvements in terms of the standardization of the analyses, the comparison of ink samples, and the interpretation of ink examination. Some of these suggestions have already been included in a DHS funded project aimed at creating a digital ink library for the United States Secret Service.
