Esta pesquisa possui como tema o abandono de crianças e adolescentes em Instituições Totais. Teve início em 2010, a partir de uma notícia publicada pela Folha de São Paulo sobre uma menina que se encontrava esquecida em uma instituição psiquiátrica há mais de quatro anos. Além dela, outras crianças vivem situações semelhantes, pelo país afora. São crianças que se encontram esquecidas pelas famílias e pelas instituições. Sem formação e cuidados adequados, estão expostas a diversas situações de abuso e violência de todos os gêneros. Tal histórico e experiência propiciam a exploração sexual e econômica, a extrema marginalização nas ruas e em instituições psiquiátricas, além de constantes passagens por Fundações Casa. Neste sentido, um discurso que legitima a exclusão é construído para responder à completa ausência de reflexão sobre decisões banalizadas que operam à revelia do sujeito humano. É um discurso que legitima o desamparo a fim de se manter a exclusão. Mesmo diante de uma aparência de inclusão, os sistemas sociais de assistência àqueles que se encontram em situação de desamparo operam de modo impessoal e segregador. A partir da análise de um discurso construído ao longo da trajetória institucional da adolescente, desde seu nascimento até completar dezenove anos, por meio da consulta de seu processo judicial, foram levantadas importantes questões a respeito do caráter político do sofrimento psíquico e de como a subjetividade é negada e mortificada pela legitimação de um discurso médico-jurídico por meio da construção de uma identidade doente e reduzida a esta finalidade. A institucionalização do saber psicológico assume a totalidade das funções de controle social que determinam o padrão de conduta socialmente aceito e a partir dessa regulação, as condutas perturbadoras que precisam ser assistidas dentro dos inúmeros serviços maquiadamente assistencialistas que trazem em seu bojo os fundamentos da exclusão e do aniquilamento do suposto sujeito psíquico / This research has as its theme the abandonment of children and adolescents in Total Institutions. Started in 2010, from some news published by Folha de Sao Paulo, about a girl who was forgotten in a psychiatric institution for more than four years. There are other children living in similar situation all over the country who are neglected by their families and by Institutions. Without training and proper care, these children are exposed to several situations of abuse and violence of all kind. Such historical and experience give rise to economic and sexual exploitation, the extreme marginalization in the streets and in psychiatric institutions, and also for their attendance at House Foundations. In this sense, a discourse that legitimizes the exclusion is built to respond to a complete absence of reflection over trivialized decisions which operate in absentia of human being. It is a discourse that legitimizes the helplessness in order to maintain the exclusion. Even before an apparent inclusion, the social assistance systems to those who find themselves in a helplessness situation operate in an impersonal and segregationist way. From the analysis of a speech built along the trajectory of institutional teenager, from birth till nineteen, by consulting his lawsuit, there were raised important issues concerning to a political character of a suffering psychic and how the subjectivity is denied and mortified by the legitimation of a speech medico legal through a construction of a sick identity and reduced to this purpose. The institutionalization of psychological knowledge takes over all of the social functions that determine a standard of social behavior accepted from that regulation, disturbing comportment which need to be assisted within numerous pretended to be social care services that bring in its concept the fundaments of exclusion and annihilation of the alleged psychic person

The title, “You simply must own your classroom”, is taken from a quote from one of my informants. After review of earlier research on how teachers handle their leadership in the meeting with disturbing pupils and which strategies they use to solve problems in the classroom, interesting questions developed. What experiences do teachers have of disturbing situations in the classroom? Which strategies do they use to solve the problems? What kind of support do the teachers consider necessary in teaching? Are there any differences in teachers’ experiences and strategies between the two selected schools? The study is supported by earlier research that deals with pupils’ and teachers’ perspective and strategies in different classroom cultures in terms of norm-breaking behaviour of pupils. The study is also supported by three different theoretical perspectives such as power structure, social order/disorder and support strategies. I conducted the study through interviews with sex teachers who work in the same municipality but in two separate schools. All teachers work in Secondary School. The study is meant to be deepening in order to gain a broader understanding of which strategies teachers use to solve problems. In my study I came to the conclusion that all teachers are most disturbed by the pupils who speak straight out and discard comments that do not even affect the substance, pupils who talk too much, do not listen and throw erasers at each other. Furthermore, I have concluded that all teachers in this study place great emphasis on social communication and individual conversation with the pupil to solve a problem. To solve the problem, the teacher should possess certain communication skills. The results have shown that all six teachers create a relationship with their pupils to counter the social disorder in the classroom. Furthermore, I concluded that teachers want to solve problems on their own, but that sometimes “extreme cases” require special support from parents, the counselor and principal at the school. Finally I concluded that the teachers call for training in leading science and conflict management, since it is missing in their teacher education.

This Master’s project deals with general aspects and possible solution of effective shielded cover and cell/chamber shielding measurement for needs of electromagnetic compatibility EMC on the basis of available norms and standards. Electromagnetic shielding is one of the most anticlutter means of EMC. Its main task is reduction of disturbing emission at the side of sources of disturbing signals as well as electromagnetic resistance increase at the side of disturbing signal receivers. Shielding is considered to be an important structural means to reduce electromagnetic field referring to a defined space part. Technical means for achieving the given goals are called shielded covers or shielded cells/chambers. Shielding is one of highly effective methods related to electromagnetic protection, for instance against power/output disturbance. To express the shielding quality so called shielding effectiveness SE is used. It represents logarithmic rate of shielding coefficient that is defined by the intensity ratios of electric and magnetic fields in a certain point of the shielded space to electric or magnetic field intensity incident/impinging on the shielded screen or wall.

Cette étude de type ethnographique a été réalisée dans une Unité localisée pour l’inclusion scolaire (Ulis). Elle vise à décrire l’expérience scolaire d’élèves qui souffrent de « troubles des fonctions cognitives » (TFC). L’observation participante est le dispositif méthodologique central de cette thèse. Après une longue période exploratoire, les « malentendus » ont été retenus comme unités d’analyse privilégiées. La typologie des « malentendus » et leur analyse montrent que les spécificités de l’expérience scolaire de ces élèves sont plutôt des accentuations de ce que vivent les élèves de classes « ordinaires ». Les TFC n’entraînent pas des différences de nature, mais de degré, dans la transmission et l’acquisition des savoirs,comparativement aux élèves en grandes difficultés dans les classes « ordinaires », mais il apparaît que de nombreux jeunes de l’Unité rejettent leur statut d’élèves handicapés et vivent mal leur scolarité dans une Unité. La confrontation des regards avec les élèves de classes« ordinaires » et le rejet de quelques-uns d’entre eux amplifient parfois ce sentiment de mal être et conduisent des jeunes de l’Unité à masquer leur appartenance à l’Ulis. Enfin, les élèves scolarisés dans l’Unité et leur famille déploient souvent une énergie considérable pour éviter une orientation dans un Institut Médico-Professionnel (IMPro), ce qui est source de tension avec les représentants de l’institution. / The ethnographic field of research of this study was conducted in a “Unité localisée pour l’inclusion scolaire (Ulis)” (located unit for school inclusion) within the French national education system. The goal of this study is to describe the actual school-life of pupils who suffer from “cognitive disturbing functions”. Participating observation is the main methodological tool in this present thesis. After a long period of exploration, the“malentendus” are chosen as privileged units for analysis. The typology of these“malentendus” and their analyses show that the specificities of the very pupils’ schoolexperience are mainly the “accentuation”, the emphasis of what pupils of ordinary classes live. Cognitive disturbing functions do not lead to a difference of nature but to a difference of intensity in the transmission and in the acquisition of knowledge, in comparison with pupils who are in great difficulties in ordinary classes; it appears that numerous pupils of that Unit reject their handicapped status and dislike their school-life in this specific structure. The confrontation with the visions of ordinary class pupils and the rejection (the casting out) of some their schoolmates amplify sometimes this feeling of discomfort and ill-being; they also lead the pupils of this very structure to mask the fact they belong to these “located units for a school inclusion” (Ulis). To finish, the pupils of that very unit and their own families try to dotheir best to avoid their children and adolescents being advised or forced to enter a medicoprofessional institute (IMPro: specific schools and homes for intellectually handicapped and disabled youngsters).

Cette thèse de doctorat établit la relation entre les représentations de l’activité physique et sportive et les attitudes à l’égard des personnes porteuses de déficience dans un contexte interculturel, celui des étudiants en mobilité temporaire de l’université de Strasbourg. Il a été établi que certaines représentations de l’activité physique et sportive principalement centrée autour de la santé et/ou la compétition ont une influence sur les attitudes à l’égard des personnes porteuses de déficience chez les étudiants étrangers. Une enquête par questionnaire en ligne (N= 399), une démarche d’entretiens semi-directifs (N=20) et un recueil de données ethnographiques ont été articulés pour obtenir le corpus empirique à analyser. Pour examiner les attitudes des étudiants étrangers à l’Université de Strasbourg, nous avons élaboré le concept de « déficience dérangeante » en nous basant sur les notions « d’inquiétante étrangeté » et le concept de « vallée dérangeante » employés respectivement dans le champ de la psychologie et le champ de la robotique. De plus, nous avons utilisé le concept de « dimension culturelle » d’Hofstede, afin de découvrir s’il existe une forme d’homogénéisation culturelle dans la perception des personnes en situation de handicap. Ce travail a permis de mettre en lumière l’existence de discours idéologique sur l’accessibilité et le sport santé, s’exprimant dans toutes les cultures chez les étudiants étrangers. Ces discours sont présents dans les représentations de l’activité physique et sportive et dans les attitudes portées à l’égard des individus porteurs de déficience, ils utilisent d’ailleurs des mécanismes similaires. Il a aussi été démontré qu’il existe chez les étudiants une dichotomie entre le corps et l’esprit qui avait une influence à la fois sur les représentations de l’activité physique et sportive, mais également sur la vision de la déficience. Cette dichotomie s’exprimant chez tous les étudiants interrogés en dépit des différences de culture, bien qu’il existe certaines nuances en fonction de la culture interrogée. Il a également été observé des similitudes entre la façon dont les sportifs de haut niveau et les personnes porteuses de déficience sont perçus par cette population. En effet, ces deux populations sont vues comme « hors norme » ou comme étant des héros. Nous démontrons comment les représentations du sportif de haut niveau sont similaires à celles des personnes en situation de handicap, et en quoi ces deux populations vivent le même processus d’altérisation. / This thesis establishes a link between physical and sporting activities and the attitudes toward disabled people. Foreign students at the University of Strasbourg are put in an intercultural context. In this context, we have demonstrated that some physical and sportive activities, which mainly focuses on health and/or competition, have an impact on the attitudes toward disabled people. Quantitative thanks to an online survey (N=399), qualitative thanks to semi directive interview (N=20) and ethnographic methods were used to establish such link. In order to analyze we have elaborated the notion of “disturbing disability,” based on the Freudian notion of “worrying strangeness,” and the concept of the “uncanny valley,” mainly used in the field of robotics. Furthermore, we have used Hofstede’s concept of “cultural dimension” to uncover a cultural homogenization in the perception of disabled people. This homogenization manifests itself in every culture through some ideological speeches that are present in the representation of physical and sporting activities, and the attitudes toward disabled people. These speeches are not identical, but both are based on the same mechanisms. This work has also illustrated that for foreign students there is a dichotomy between mind and body that expresses itself in every culture, and has an influence in the perception of physical and sporting activities, as well as on disability. Finally, in this thesis we have proven that both athletes and disabled people are seen as “special”, “inhuman” or “heroic” because they both go through the same “othering” process.
