Living without Existing: The Permanent Vegetative State

The situation of persons in a permanent vegetative state, characterized as a state of wakefulness without awareness, raises ethical issues concerning the meaning of a life extended by artificial nutrition and hydration. Incarnating paradoxes which question the boundaries between life and existence, these patients lead us to consider new categories of Being: how do we talk about a ‘non-existent human being’? 要旨 覚醒状態にありながらも意識を持つことができないという特徴をもつ持続的植物状態に陥った人間の状態は、人工的水分栄養補給によって延命することの倫理的な問題を提起する。生きる事と存在する事の境界線を問い直す矛盾を突きつけることで、植物状態の患者は我々に新しい生命の分類について示唆する。「存在しない人間」をどう議論すればよいのだろうか

Piezoelectric and optical setup to measure an electrical field: Application to the longitudinal near-field generated by a tapered coax

We propose a new setup to measure an electrical field in one direction. This setup is made of a piezoelectric sintered lead zinconate titanate film and an optical interferometric probe. We used this setup to investigate how the shape of the extremity of a coaxial cable influences the longitudinal electrical near-field generated by it. For this application, we designed our setup to have a spatial resolution of 100 um in the direction of the electrical field. Simulations and experiments are presented

Components of effective peer helper programs

Peer helper programs have increasingly been implemented in elementary, middle, and high schools, and must be developmentally appropriate for each grade level. Peers can serve as tutors, mentors, mediators, and support systems, and schools utilize peer helper programs in order to assist other students in these areas. Effective peer helper programs share common characteristics. The purpose of this paper is to examine characteristics of effective peer helper programs. These programs incorporate peer helper roles, training considerations, developmental considerations, characteristics of peer helpers, screening and selection procedures, program service and delivery, supervision and evaluation needs, and school/community needs

Archéologie des sites ornés de Dordogne : cadre conceptuel, potentiels et réalité

Le projet collectif de recherche termine sa deuxième année d’une autorisation triennale et troisième année effective. Avec pour objectif l’étude des grottes et abris ornés dans une perspective transversale, à partir de la plus grande concentration de sites ornés (interfluve Vézère-Dordogne, entre la Couze et le Pontou, comprenant les vallées des Beunes), le PCR s’appuie sur une équipe pluridisciplinaire d’une vingtaine de personnes, rassemblant des compétences et des communautés d’intérêt dan..

Longitudinal Electrical Near-field generated by a Tapered Coax and studied with a Piezoelectric Film coupled with an Optical Probe

International audienceWe investigated the influence of using a conical end on the longitudinal electrical near-field generated by a coaxial cable. Simulations with Finite Integration Technique show that this influence greatly varies along the longitudinal axis. Experimental measurements were also carried out. To that purpose, we designed a new set-up to measure the electrical field in one direction with a spatial resolution of 100 microns in this direction, with nearly no perturbation by the other components of the field. This set-up uses a piezoelectric sintered PZT film and a heterodyne laser probe

Le solstice d’hiver et les traditions de Noël

Nos fêtes hivernales trouvent en grande partie leur origine dans des célébrations ancestrales ; de l’Antiquité à nos jours, elles ont été modifiées, détournées, abandonnées ou amplifiées. Déjà, dans l’ancienne Rome, le solstice d’hiver était célébré et donnait lieu aux Saturnales où l’on revivait l’Âge d’Or, temps mythique où tous les hommes étaient égaux. Ces fêtes, plus sages que ce que l’usage du mot laisse entendre, étaient marquées par de grands banquets domestiques où les esclaves, prof..
