Moral no mundo adulto: a visão dos jovens sobre os adultos de hoje

The present study core issue is, how do today's youth judge adults concerning their moral criteria? The issue is twofold relevant for the ethical and moral education of adolescents, both for knowledge on their moral development and for their apparent desertion from the public sphere, favouring the private one. This study aimed at knowing how youth judge adults on moral grounds, while verifying whether youth do clearly separate public and private spheres. Two different surveys were carried out: survey 1 (S1) with 520 students who answered a 24-item closed questionnaire plus two open-ended questions; in S2 a 14-item questionnaire was applied to 36 students, followed by group debate on the issue. This article analyses issues dealt with at both surveys, as well as issues only inquired on at S1. Results show some mistrust among youth toward adult morality. Most don't consider them ethical and, in general, criticise the way they conduct the public sphere. Furthermore, they question adults' virtues, deeming egoism or self-interest to be their worse defect, associated to their sole concern with the private sphere. The adolescents were divided as to wisdom, accountability, and trust assigned to adults. Nevertheless, the image they present of their elders is relativised, according to whether they refer to public or private sphere adults.A pergunta central desta pesquisa é: como os adolescentes da atualidade julgam os adultos no que se refere essencialmente a critérios morais? Responder a essa indagação possui relevância para a formação ética e moral dos alunos devido a duas razões principais: a primeira refere-se ao desenvolvimento moral do adolescente; a segunda, à aparente deserção do espaço público por parte dos jovens em favor do espaço privado. Nesse sentido, o objetivo do presente trabalho foi verificar como os jovens julgam moralmente os adultos e se, de fato, eles operam uma clara cisão entre as esferas privada e pública. Foram realizadas separadamente duas pesquisas: no estudo 1 (E1), utilizou-se um questionário fechado de 24 questões e duas questões abertas; no estudo 2 (E2), além da aplicação de um questionário com 14 perguntas, foi realizado um debate em grupo acerca delas. É importante ressaltar que, neste artigo, são analisadas tanto questões presentes nos dois estudos, quanto algumas presentes apenas no E1. Os resultados obtidos mostram certa desconfiança dos jovens em relação à moralidade dos adultos. A maioria não os considera pessoas éticas e, de forma geral, critica sua condução da esfera pública. Além disso, os jovens questionam as virtudes dos adultos e consideram o egoísmo como o maior defeito deles, associando-o a uma preocupação exclusiva com a esfera privada. Dividem-se quanto à sabedoria, à responsabilidade e à confiança atribuída aos adultos de hoje. Os dados apontam, ainda, que a imagem do adulto apresentada é relativizada a partir da distinção entre os adultos da esfera pública e aqueles da esfera privada

Apoptotic HPV Positive Cancer Cells Exhibit Transforming Properties

Previous studies have shown that DNA can be transferred from dying engineered cells to neighboring cells through the phagocytosis of apoptotic bodies, which leads to cellular transformation. Here, we provide evidence of an uptake of apoptotic-derived cervical cancer cells by human mesenchymal cells. Interestingly, HeLa (HPV 18+) or Ca Ski (HPV16+) cells, harboring integrated high-risk HPV DNA but not C-33 A cells (HPV-), were able to transform the recipient cells. Human primary fibroblasts engulfed the apoptotic bodies effectively within 30 minutes after co-cultivation. This mechanism is active and involves the actin cytoskeleton. In situ hybridization of transformed fibroblasts revealed the presence of HPV DNA in the nucleus of a subset of phagocytosing cells. These cells expressed the HPV16/18 E6 gene, which contributes to the disruption of the p53/p21 pathway, and the cells exhibited a tumorigenic phenotype, including an increased proliferation rate, polyploidy and anchorage independence growth. Such horizontal transfer of viral oncogenes to surrounding cells that lack receptors for HPV could facilitate the persistence of the virus, the main risk factor for cervical cancer development. This process might contribute to HPV-associated disease progression in vivo

Développement et caractérisation d un ASIC de lecture de macro-cellule de photo-détecteurs de grande dimension

PMm est un projet financé pour 3 ans (2007-2010) par l Agence Nationale de la Recherche (ANR) dont le titre exact est Electronique innovante pour photo-détecteurs distribués en physique des particules et astroparticule . Le projet PMm propose de segmenter les grandes surfaces de photo-détection en macro modules de 16 PMTs de 12 (2x2 m ), connectés à une électronique innovante autonome qui fonctionne en déclenchement automatique et est installé proche des PMTs. Ce développement est rendu possible par les progrès de la microélectronique qui permettent d'intégrer la lecture et le traitement des signaux de tous ces photomultiplicateurs à l intérieur d un même circuit intégré (ASIC) baptisé PARISROC (Photomultiplier ARray Integrated in SiGe Read Out Chip) et seules les données numérisées sont ensuite expédiées par réseau vers le système de stockage des données en surface. Le circuit PARISROC, réalisé en technologie AMS SiGe 0.35 m, contient 16 voies totalement indépendantes correspondant aux 16 PMTs de chaque module. Chacune de ces voies permet la lecture de la charge du signal reçu ainsi que du temps associé. Le premier prototype du circuit PARISROC a une surface totale de 19 mm2. Il a été envoyé en fabrication en juin 2008 chez Austrian Micro-System (AMS) par l intermédiaire du centre de multi-projet CMP (à Grenoble), puis livré au laboratoire en décembre 2008. Les mesures effectuées sur l ASIC ont conduit à la réalisation d un second prototype. Des améliorations notables ont été apportées, en termes de bruit, de dynamique, de vitesse de lecture du chip (passage des horloges de 10 MHz à 40 MHz), de mesure de temps (améliorations de la TDC), de mesure de charge (améliorations du shaper lent). Envoyé en fabrication en novembre 2009 et reçu au laboratoire en février 2010, ce nouveau prototype PARISROC 2 a été testé en laboratoire et l analyse a montré un comportement général correct et la réalisation des modifications apportées.PMm is a project founded for three years by the French National Agency for Research (ANR) with the complete title: Innovative electronics for photo-detectors array used in high energy physics and astroparticles . The project proposes to segment the large surface of photo-detection in macro pixel consisting of an array of 16 PMTs of 12-inches (2*2 m ), connected to an autonomous front-end electronics which works in a triggerless data acquisition mode placed near the array. This is possible thanks to the microelectronics progress that allows to integrate the read out and the signal processing, of all the photomultipliers, in the same circuit (ASIC) named PARISROC (Photomultiplier ARray Integrated in SiGe Read Out Chip). The ASIC must send out only the digital data by network to the surface central data storage. The PARISROC Chip, made in AMS 0.35 m technology, integrates 16 independent channels for each PMTs of the array, providing charge and time measurements. The first prototype of PARISROC chip has a total surface of 19 mm . It has been sent for fabrication in June 2008 to AMS foundry (AustriaMicroSystems) through the CMP (Multi Project Center) and received in December 2008. The ASIC measurements have led to the realization of a second prototype. Important measurements were brought in terms of noise, dynamic range, read out frequency (from 10 MHz to 40 MHz), time measurements (TDC improvements) and charge measurements (Slow shaper improvements). Sent for fabrication in November 2009 and received in February 2010, this new prototype PARISROC 2 has been tested and the characterisation has shown a good overall behavior and the verification of the improvements.ORSAY-PARIS 11-BU Sciences (914712101) / SudocSudocFranceF
