Craniofacial reconstruction as a prediction problem using a Latent Root Regression model

In this paper, we present a computer-assisted method for facial reconstruction. This method provides an estimation of the facial shape associated with unidentified skeletal remains. Current computer-assisted methods using a statistical framework rely on a common set of extracted points located on the bone and soft-tissue surfaces. Most of the facial reconstruction methods then consist of predicting the position of the soft-tissue surface points, when the positions of the bone surface points are known. We propose to use Latent Root Regression for prediction. The results obtained are then compared to those given by Principal Components Analysis linear models. In conjunction, we have evaluated the influence of the number of skull landmarks used. Anatomical skull landmarks are completed iteratively by points located upon geodesics which link these anatomical landmarks, thus enabling us to artificially increase the number of skull points. Facial points are obtained using a mesh-matching algorithm between a common reference mesh and individual soft-tissue surface meshes. The proposed method is validated in term of accuracy, based on a leave-one-out cross-validation test applied to a homogeneous database. Accuracy measures are obtained by computing the distance between the original face surface and its reconstruction. Finally, these results are discussed referring to current computer-assisted reconstruction facial techniques.     

The household effect on electoral participation. A contextual analysis of voter signatures from a French polling station (1982–2007)

We use electoral participation data coded from signature lists to show that patterns of voter turnout, be they related to average participation, versatility or precise moments of voting, are strongly related to what we call “electorate households”, i.e. groups of voters registered in the same polling station and living together. Each household tends to be homogeneous, at levels much higher than chance would explain, so that modelling individual participation without taking this household effect into account ignores much of what actually happens. The status in the household also plays an important role among individual factors of voter participation. Not only do people who live together often participate together, but the precise shape of their relationships influences their behaviour.

Civil and civic death in the new authoritarianisms: punishment of dissidents through juridical destruction,ethical ruin,and necropolitics in Turkey

ABSTRACT

Since the Turkish government’s recent turn to authoritarianism, tens of thousands of public dissidents and government critics have been subjected to dismissals and revocation of civic rights via emergency decrees. The victims call this process ‘civil death’. We aim to understand the logic behind this form of punishment in Turkey by examining the differential genealogy of civil death in the work of Hannah Arendt, Bertrand Ogilvie, Giorgio Agamben, and Achille Mbembe. We demonstrate that a later form of civil death was used by totalitarian regimes in a process leading to the reduction of targeted individuals as ‘superfluous’ and as ‘living corpses’ in concentration camps. In these contexts, death became an instrument of biopolitical and necropolitical powers. We propose that although contemporary punishment of public dissidents in Turkey shares some similarities with these forms of civil death, it may more fittingly be identified as civic death. We argue that while civil death is based on the classical political right of the sovereign to ‘make die’ after first reducing targeted individuals to little more than living corpses, civic death is linked to the power of the sovereign to ‘let die’ through the exclusion of public dissidents from economic, social, and political life.     

Validation of a method to detect cocaine and its metabolites in nails by gas chromatography-mass spectrometry

The objective of the present work was to compare previously published methods and provide validation data to detect simultaneously cocaine (COC), benzoylecgonine (BE) and norcocaine (NCOC) in nail. Finger and toenail samples (5mg) were cut in very small pieces and submitted to an initial procedure for external decontamination. Methanol (3 ml) was used to release analytes from the matrix. A cleanup step was performed simultaneously by solid-phase extraction (SPE) and the residue was derivatized with pentafluoropropionic anhydride/pentafluoropropanol (PFPA/PFP). Gas chromatography-mass spectrometry (GC-MS) was used to detect the analytes in selected ion monitoring mode (SIM). Confidence parameters of validation of the method were: recovery, intra- and inter-assay precision, as well as limit of detection (LOD) of the analytes. The limits of detection were: 3.5 ng/mg for NCOC and 3.0 ng/mg for COC and BE. Good intra-assay precision was observed for all detected substances (coefficient of variation (CV)<11%). The inter-assay precision for norcocaine and benzoylecgonine were <4%. For intra- and inter-assay precision deuterated internal standards were used. Toenail and fingernail samples from eight declared cocaine users were submitted to the validated method.

Pellagra: a rare disease observed in a victim of mental and physical abuse

Lesions of the brain stem and cerebellum due to nutritional deficiencies are mostly seen in chronic alcohol abuse and more rarely in severe malnutrition. We report the case of a 27-year-old woman, found dead in the family flat. She presented cachexia (167 cm, 25 kg) and multiple hematomas of the limbs. Postmortem examination revealed lesions due to peritonitis. Neuropathological examination showed severe atrophy of the corpus callosum and central neuronal chromatolysis, which are observed in pellagra. Inflammatory colitis or celiac disease was not found. Toxicological analysis was negative, in particular no alcohol absorption. Pellagra, which is due to nicotinamide deficiency, is a disease rarely seen in this country. In this case, nutritional deficiency was the consequence of failure to eat in a context of abuse. The woman was born of an incestuous relationship and presented intellectual retardation due to poor affective relations with her mother.     

From the Morality of Living to the Morality of Dying: Hunger Strikes in Turkish Prisons

Political hunger strikes have been part of the debates on human rights in many countries around the world. This paper explores the preconditions for and motives behind hunger strikes in Turkey by conceiving the hunger strikers as a part of citizenship politics through which strikers not only express their views against certain common issues, but also declare total opposition to an unjust condition within their political community. The paper focuses on the question of why some such “citizens” choose to participate in hunger strikes, which appears as an individual commitment to achieve a certain common objective. In doing so, the meaning of the experiences of hunger strikers and their universal right to live are elaborated in relation to their political and moral views. Hunger strikes are suggested to be seen as voluntary fasting, undertaken as a means of civil disobedience against an injustice within the context of citizenship. As examples of non-violent political acts, hunger strikes are not only part of citizenship politics but also expressions of commitment to achieving one's goals through non-aggressive means for the common good of all citizens. Moreover, they can also be considered examples of martyrdom/heroism because hunger strikers altruistically risk their life for a public cause. As a particular altruistic act, hunger strikes can also be viewed as an effective form of communication directed toward fellow citizens. Moreover, they are expressions of self-determination for having control over and for one's own life conditions. Finally, hunger strikes can be conceptualized as a struggle for transforming the configuration of structures and practices of citizenship about which one is passionately concerned. In this context, hunger strikes seem to be struggles for recognition in a relationship between two subjects, in which one subordinates the other.
