Cette thèse montre en quoi l'analyse de l'activité des professeurs des écoles enseignant une Langue Vivante Etrangère peut apporter des connaissances utiles au processus de formation continue de ces maîtres au sein de leur polyvalence. L'activité humaine est invisible tant pour les observateurs que pour les acteurs eux-mêmes, d'où notre recours au cadre théorique et méthodologique de l'analyse ergonomique de l'activité enseignante qui s'inscrit dans une perspective historico-culturelle et se nourrit des apports féconds d'une clinique de l'activité. La Méthode d'Auto Confrontation, méthode indirecte, nous permet la création d'un milieu spécifique où nous prenons en compte l'expérience des enseignants et où nous cherchons à transformer le travail pour le comprendre. Nous nous sommes appuyés sur l'analyse de l'activité de six enseignants engagés dans l'enseignement de l'anglais afin de rendre compte de leurs manières de faire, des arbitrages et compromis à l'oeuvre. Une première représentation des pratiques enseignantes laisse ainsi apparaître trois registres d'action principaux liés à leur maîtrise de la conduite de classe, à leur connaissance de la démarche didactique et pédagogique de l'enseignement des LVE et à leur maîtrise de la langue cible. Un processus spécifique lié à la confiance en soi a émergé en cours d'analyse et joue un rôle central dans leur activité. Un nouvel éclairage de la polyvalence est alors envisagé où nous proposons une rencontre entre analyse du travail et formation. La « mise en situation active » (MSA) décline les perspectives découlant de la visée technologique de notre recherche. / This thesis shows how the analysis of the activity of the school teachers teaching a Foreign Language can bring useful knowledge to the process of ongoing training to these teachers within the core of their versatility. Human activity is invisible as much for the observers as for the actors themselves, which leads us to fall back on the theoretical and methodological frameworks of the ergonomic teaching activity which joins a historical-cultural perspective and is fed by the fertile contributions of a clinic of activity. The method of Self-Confrontation, an indirect method, allows us to create a specific space where we take into account the experience of the teachers and where we seek to transform the work in order to understand it. We turned to the analysis of the activity of six teachers engaged in the teaching of English in order to report on their methods, their judgments and compromises in action. A primary representation of their teaching practices thus allows three principle registers of action linked to their mastery of classroom management, to their knowledge of the didactic and pedagogical process of the teaching of Foreign Languages and their mastery of the target language. A specific process linked to self-confidence emerged during the course of the study and played a central role in their activity. A new understanding of versatility is thus envisioned where we propose to link the work analysis and training. The "put into live action" breaks down the perspectives coming from our targeted online research.

It is also pointed out that they also derive from the fundamental rights of freedom and property contained in Article 5 of the Constitution, giving them normative density or specific meaning in the field of taxes. This association is possible due to the opening clause inscribed in paragraph 2 of article 5 of the Constitution. It is shown that if legality, isonomy, nonretroactivity, priority, the prohibition of tribute with confiscatory effect and immunities are fundamental rights, they will also constitute fundamental precepts. It is maintained that noncompliance with these guarantees of the taxpayers by act of the Public Authority makes it possible to join the Supreme Court by means of the Arrangement of Non-compliance with Basic Precept, covered by Article 102, paragraph 1 of the Federal Constitution and regulated by Law n . 9,882 / 99. In the end, it is demonstrated that by means of the non-compliance argument, any act or omission of the Public Power, whether normative or non-normative, abstract or concrete, prior or subsequent to the Federal, State or Municipal Constitution, and from any body or entity of the Legislative, Executive and Judiciary / Afirma-se que as limitações ao poder de tributar constantes do artigo 150 da Constituição Federal constituem, na verdade, direitos fundamentais dos contribuintes, porque desempenham uma dupla função no plano subjetivo continuam a atuar como garantia da liberdade individual; e no plano objetivo assumiram uma dimensão institucional a partir da qual seu conteúdo deve funcionalizar-se para a consecução dos propósitos e valores proclamados constitucionalmente. Aponta-se que também decorrem dos direitos fundamentais da liberdade e propriedade constantes do artigo 5º da Constituição, conferindo-lhes densidade normativa ou significado específico no campo dos tributos. Essa associação mostra-se possível por força da cláusula de abertura insculpida no § 2º do artigo 5º da Constituição. Demonstra-se que se a legalidade, a isonomia, a irretroatividade, anterioridade, a vedação ao tributo com efeito confiscatório e as imunidades configuram-se direitos fundamentais, configurarão, também, preceitos fundamentais. Sustenta-se que o descumprimento dessas garantias dos contribuintes por ato do Poder Público faz surgir a possibilidade de ingresso ao Supremo Tribunal Federal por via da Arguição de Descumprimento de Preceito Fundamental, encampada no artigo 102, § 1º da Constituição Federal e regulamentada pela Lei n. 9.882/99. Ao final, demonstra-se que por meio da arguição de descumprimento controla-se qualquer ato ou omissão do Poder Público, seja normativo ou não normativo, abstrato ou concreto, anterior ou posterior à Constituição, federal, estadual ou municipal, e proveniente de qualquer órgão ou entidade do Legislativo, Executivo e do Judiciário

For this purpose, a brief historical review of social assistance policies was produced in order to understand the current scenario, marked by neoliberal reforms. The study, from an ethnographic inspiration, there was basically through three stages. At first, the researcher followed meetings with the CREAS team. For each meeting it was developed a Field Diary. In the second, the researcher conducted reflexive interviews with four workers. The third and last, was developed the interpretation, analysis and discussion of the collected material in the previous steps. This process revealed the constant changes that the work in public service suffers according to Social Assistance policies in the municipality and its relationship with neoliberal processes in the broadest sense. If, on the one hand, despite this context, the workers have the capacity to also turn on and organize their activities, giving new meanings, collectively, on the other, it was observed that the mental strain is present in their daily lives. It seems to be associated to the numerous impediments to the realization of the work activity raised by management, as well as the workload related to the nature of services to families who have suffered violations of their rights. To handle these situations, the workers take more individual tactics rather than a collective organization. / A presente disserta??o, situada na linha de Pesquisa Preven??o e Interven??o Psicol?gica do Programa de P?s-gradua??o Stricto Sensu da Pontif?cia Universidade Cat?lica de Campinas, busca investigar o poder de agir de trabalhadoras do Centro de Refer?ncia Especializado de Assist?ncia Social (CREAS) de um munic?pio do interior do estado de S?o Paulo. Para tanto, realizou-se um breve resgate hist?rico das pol?ticas de assist?ncia social, a fim de entender o atual cen?rio, marcado pelas reformas neoliberais. O estudo, de inspira??o etnogr?fica, deu-se, basicamente, atrav?s de tr?s etapas. Na primeira, o pesquisador acompanhou reuni?es junto ? equipe do CREAS. Para cada reuni?o foi desenvolvido um Di?rio de Campo. Na segunda, o pesquisador realizou entrevistas reflexivas com quatro trabalhadoras. Na terceira e ?ltima, realizou-se a interpreta??o, an?lise e discuss?o do material levantado nas etapas anteriores. Este processo revelou as constantes mudan?as que o trabalho nesse servi?o p?blico sofre de acordo com as pol?ticas de Assist?ncia Social no munic?pio e sua rela??o com processos neoliberais mais amplos. Se, por um lado, apesar desse contexto, as trabalhadoras possuem relativa capacidade de tamb?m transformar e organizar suas atividades, atribuindo novos sentidos, coletivamente, por outro, observou-se que o desgaste mental est? presente no seu cotidiano. Ele parece estar associado aos in?meros impedimentos para a realiza??o da atividade de trabalho colocados pela gest?o, bem como pela carga de trabalho relacionada ? natureza do atendimento a fam?lias que sofreram viola??es de seus direitos. Para lidar com essas situa??es, as trabalhadoras se valem mais de t?ticas individuais do que de uma organiza??o coletiva.

La prise en compte du bien-être des animaux dans les élevages suscite de vives controverses dans la société et dans les champs scientifique, technique et professionnel. Dans le milieu scolaire, le bien-être animal (BEA), en tant que question socialement vive (Legardez & Simonneaux, 2006), pose des difficultés pour son enseignement et son apprentissage dans les lycées professionnels agricoles préparant les futurs éleveurs. Cette thèse a pour objet de comprendre comment le pouvoir d’action (Clot, 1999) des enseignants et des élèves relatif à la prise en compte du BEA en situations d’enseignement-apprentissage se développe (ou ne se développe pas). Nous articulons les cadres théoriques et méthodologiques de la didactique des questions socialement vives, de la clinique de l’activité et du jugement éthique. Dans une double visée transformative et épistémique, quatre enseignants de zootechnie et leur classe de baccalauréat professionnel ont participé à un protocole d’intervention en lycées. A partir des traces des activités dialogiques recueillies, nous avons documenté les émotions, les jugements éthiques et les représentations-connaissances signifiés ainsi que leurs interactions et les conflits à l’œuvre dans le développement possible et impossible du pouvoir d’action des sujets relatif à la prise en compte du BEA en élevage. L’ensemble des résultats permet de mettre à jour des obstacles et des leviers au développement du pouvoir d’action des élèves et des enseignants. Nous formulons plusieurs propositions pour la formation des enseignants et des élèves afin de les accompagner à affronter certains obstacles et à davantage valoriser les leviers potentiels pour augmenter leur champ des possibles. / The question of farm animal welfare has sparked strong debate in society and in scientific, technical and professional domains. In the field of education, teaching and learning about farm animal welfare (FAW) as a socially acute question (Legardez & Simonneaux, 2006), is particularly problematic in agricultural schools which train future breeders. The aim of this thesis is to understand how the power to act (Clot, 1999), in relation to the question of FAW, develops (or not) in both teachers and students during teaching-learning situations. We articulate the theoretical and methodological frameworks of the didactics of socially acute questions, the clinic of activity and ethical judgment. Four animal husbandry teachers participated in a protocol with their vocational baccalaureate students. Based on their dialogical activities, we recorded their emotions, ethical judgments and knowledge-representations systems along with their interactions and the conflicts at work to help or hinder the development of their power to act.Our results reveal the barriers and the facilitators to the development of the students’ and teachers’ power to act to improve FAW. We make several recommendations for the training of teachers and students which should help them to overcome certain hurdles and further exploit the potential levers allowing them to widen their range of possibilities.

Au cours des quinze dernières années, les professionnels des ressources humaines ont été de plus en plus mobilisés dans la gestion des questions de santé et sécurité au travail (notamment pénibilité, risques psychosociaux, handicap). Toutefois, les problèmes de santé et sécurité au travail (SST) sont complexes et les professionnels des ressources humaines peuvent éprouver des difficultés à les mettre en congruence avec toutes les missions attenantes à leur fonction. Dans cette thèse, nous proposons de regarder les professionnels RH comme des travailleurs à part entière et d’analyser leur activité de gestion des enjeux de SST dans une approche ergonomique. Notre objectif est d’identifier les déterminants qui génèrent de l’empêchement dans leur activité ou qui permettent de développer leurs marges de manœuvre. Notre analyse se base sur une intervention-recherche de quatre ans dans un groupe de l’industrie chimique. Dans le cadre de cette intervention, nous avons accompagné des professionnels RH, en particulier dans le déploiement d’un accord paritaire sur la prévention de la pénibilité du travail. Nous sommes ainsi parvenu à assembler de nombreuses données sur l’activité des professionnels RH dans le cadre de notre accompagnement. Parallèlement, nous avons également mis en œuvre diverses méthodologies de collecte de données (entretien, chronique d’activité, recueil de courriels). Les résultats de notre analyse mettent en lumière plusieurs sources d’empêchement dans le travail de prévention des professionnels RH : balkanisation de la fonction RH, déficit de régulation conjointe entre leurs prescripteurs, manque de légitimité, hypertrophie des relations sociales, manque d’espaces de débat sur leur travail. Mais nos résultats mettent aussi en évidence la capacité des professionnels RH à développer leur pouvoir d’agir. Ce développement passe en particulier par la construction de collectifs de travail et la réalisation d’activités collectives, au sein de la fonction RH et avec d’autres fonctions clés de l’entreprise. Enfin, notre analyse montre que les ergonomes peuvent être des contributeurs essentiels au développement du pouvoir d’agir des professionnels RH, en participant notamment à l'élaboration d'objets-frontières et d'objets transactionnels utiles aux échanges avec d’autres fonctions de l’entreprise. / Over the past fifteen years, human resource professionals have increasingly been involved in the management of occupational health and safety issues (especially arduousness of the work, psychosocial risks, disability at work).However, occupational health and safety (OHS) issues are complex and human resource professionals may find it difficult to match them with all the missions attached to their function.In this thesis, we propose to look at HR professionals as full part workers and to analyze their OHS management activity in an ergonomic approach. Our objective is to identify the determinants that generate impediments in their activity or that allow them to develop their leeway.Our analysis is based on a four-year research-intervention in a chemical industry group. As part of this intervention, we have assisted HR professionals, particularly in the implementation of a joint agreement on the prevention of the arduousness of the work. Thereby, we manage to assemble a significant amount of data regarding the activity of HR professionals in the context of our support. In addition, we have also implemented various data collection methodologies (interview, activity chronicle, e-mail mining).The results of our analysis highlight several sources of impediments in the prevention work of HR professionals: balkanization of the HR function, deficiency of joint regulation among their prescribers, lack of legitimacy, hypertrophy of social relations, void of spaces for work debate.However, our results also highlight the ability of HR professionals to develop their power to act. This development involves the construction of work collectives and the realization of collective activities, within the HR function and with other company stakeholders.Finally, our analysis shows that ergonomists can be essential contributors to the development of the power to act of HR professionals, especially by participating in the creation of border objects and transactional objects useful for exchanges with other functions of the company.

Cette thèse s’intéresse à la problématique de l’apprentissage du métier infirmier. Elle est envisagée depuis la capacité des étudiants infirmiers à porter la responsabilité de leurs actes et à assumer la performance de leurs pratiques en regard de leur identité professionnelle. L’objectif est d’étudier la contribution de l’analyse de l’activité soignante des étudiants à leur développement identitaire durant cette activité réflexive. La méthode historique indirecte de clinique de l’activité a provoqué le développement de leur pensée à la fois sur leur manière de faire le métier et leur manière d’être face au métier qu’ils apprennent. L’observatoire dialogique créé à partir de quatre étudiants infirmiers et de quatre formatrices a permis d’appréhender comment l’activité discursive entre étudiants sur un soin réalisé a participé consubstantiellement à la transformation de leur soin et de leur identité professionnelle. En outre, les formatrices ont discuté de la mise en patrimoine au sein de la formation des compromis élaborés par les étudiants et ont questionné leurs propres activités. Leurs échanges, construits à partir de l’image vidéo des controverses des étudiants, leur ont permis de mieux cerner l’intérêt du débat de métier afin qu’ils puissent s’émanciper de la tâche prescrite. Les étudiants infirmiers sont devenus des ressources pour l’organisation apprenante. Le modèle d'analyse proposé peut donc être utile aux formateurs en soins infirmiers ainsi qu’aux tuteurs de stage. / This thesis focuses on issues experienced by nursing students when learning their trade. These issues are considered from their ability to endorse the responsibility of their acts to their assumption of performance of their practices in light of their professional identity. The aim was to study the contribution of the nursing students’ activity analysis to the development of their professional identity throughout this reflexive activity. The indirect historical method of the clinical approach of activity has induced the development of the student’s reflection both on their way nursing and on their way of being regarding the profession they are learning. The dialogic observatory generated both by four nursing students discussing their care and by four expert trainers analyzing these reflections, has highlighted how the discursive activity between students has contributed to transform their care and their professional identity all together. Moreover, the trainers have discussed capitalizing students’ agreements for further use in teaching and questioned their own practices. Their exchanges, built upon watching significant video extracts of students’ confrontations, led them to a better understanding of how the students may go beyond the set tasks. The nursing students have thus become resources for the learning organization. The proposed analysis model can therefore be useful to nursing trainers as well as tutors.

Master thesis discusses the growing need of electric energy storage and its effectivity and capacity. It describes an overview of possible technologies with their advantages and disadvantages. Greater attention is paid to the storage of energy in gas, so-called Power to Gas, which combines the electrolytic production of hydrogen from water and the Sabatier reaction to produce synthetic methane. This technology is introduced in the so-called SIT Brno cycle of Siemens Industrial Turbomachinery company. The main part of the thesis is focused on the description of this cycle and on the calculation of the steam-gas turbine (high-pressure and low pressure module). This thesis describes the methodology of turbine calculation and the composition of the steam gas mixture after combustion of methane. The carbon dioxide formed by combustion in the steam-gas mixture generator was replaced by steam. Part of the diploma thesis are drawings of cross-section of individual turbine modules.

La thèse porte sur la caractérisation expérimentale des pertes singulières dans les matériaux magnétiques au sein d’actionneurs électromécaniques conçus pour le développement du programme « avion plus électrique », où la maîtrise des pertes d’énergie est un enjeu absolument majeur. Ce programme, de portée mondiale, vise, entre autre, à remplacer, dans l’avion, les actionneurs hydrauliques par des actionneurs électromécaniques, quand c’est possible.Par pertes singulières on entend toutes les pertes liées aux contraintes magnéto-mécano-thermiques liées d’une part à la mise en œuvre (découpe, assemblage contraint, isolation, traitement thermique...) des matériaux et d’autre part aux conditions réelles de fonctionnement (champ tournant, haute fréquence, saturations locales...) au sein des machines électriques (HV/HF), et qui sont très difficiles à estimer précisément de façon analytique ou via les dispositifs conventionnels de tests. Ces sollicitations influencent les caractéristiques de tôles qui peuvent s’éloigner significativement des données du fabricant (donc fausser le calcul des performances).Au début de cette thèse on s’est focalisé sur le montage d’un banc d’essai évolutif équipé de moyens de mesure directe du couple et d’une machine d’entraînement (8 ktr/min ; 42 kW) tarée par nos soins. Sur cette dernière une longue campagne d’essais a été menée pour isoler les différentes composantes de pertes, dont, par exemple, les pertes mécaniques (par frottement dans les roulements + aérodynamiques) qui ont été quantifiées via un rotor neutre. Les pertes dans les aimants sont indissociables des pertes fer, donc, elles ont été estimées par le biais d’une modélisation par éléments finis tridimensionnelle. Les pertes dans la frette de maintien sont nulles du fait qu’elle est isolante (thermo-rétractable). Le bobinage utilisé dans ce moteur est très particulier, à barres massives (remplissage de cuivre dans l’encoche jusqu’à 90%), développé dans notre laboratoire IES. Les pertes atypiques au sein de ce bobinage spécial ont été profondément abordées dans ces travaux (effet de refoulement de courants, pertes aux extrémités de la machine...).Dans la dernière partie de cette thèse, nous avons exploré le fonctionnement des machines synchrones à aimants à haute fréquence afin d’accroître la densité de puissance de nos moteurs (pour franchir la barre de 2.5 kW/kg). Pour ce faire, après une étude détaillée, nous avons proposé en premier lieu un prototype avec des matériaux standard (stator FeCo Vacodur49 0.2mm, rotor FeSi, aimants NdFeB nuance N35EH, bobinage à barres cuivre) fonctionnant à 1666 Hz, tournant à 5000 tr/min, avec une densité de puissance de 4.5 kW/kg et un rendement de 94%. En second lieu, nous avons proposé un deuxième prototype de rendement plus faible (93%) mais qui a une densité de puissance proche de 6 kW/kg avec un rotor sans fer et un bobinage en Aluminium.Avant le montage final de ce prototype modulaire, nous avons effectué des mesures de pertes magnétiques, en conditions réelles de fonctionnement d’un moteur électrique, sur une multitude de tôles FeSi et FeCo (Vacodur49, NO20, M270-35A) avec la variation de différents procédés de fabrication: isolation (vernis thermo-collant « back-lack », vernis C5), découpe (laser, électroérosion) et traitement thermique. Pareillement, toutes les pertes mises en jeu ont été séparées (mécaniques, par courants induits dans les viroles...) pour pouvoir remonter aux pertes magnétiques et, donc, enfin, quantifier empiriquement le coefficient de majoration de pertes fer. / The main aim of this thesis was to study and experimentally assess the additional iron losses in the stator (electrical lamination steel) of high performance permanent magnet synchronous machines (PMSM) designed for aircraft applications, in relation with the “more-electric-aircraft” project. This international program consists of gradually introducing electrical systems to replace onboard hydraulic and pneumatic systems, for example to power the landing gear wheels (Electric Green Taxiing System)…The extra iron losses are caused by manufacturing processes (cutting, sticking, insulation, stacking, pressing, shrink-fitting, thermal treatment …) and the real conditions of use of electrical motor (namely: rotational flux, saturation, high frequency…). Indeed, the mechanical and thermal stresses during the manufacturing steps can deteriorate the magnetic properties of the material and significantly increase the iron losses. These aspects are difficult to accurately evaluate by analytical models or standard measurements (Epstein frame…) and require experimental assessment to precisely calculate the motor efficiency.First of all, we started by developing a test bench equipped with drive motor: PMSM 8000 RPM ; 42 kW. For accurate assessment, the losses in this machine are separated on the test bench, for example, the mechanical losses (bearings loss & windage loss) have been measured at different speed with a non-magnetic rotor. Rotor magnets eddy-current losses cannot be isolated from iron losses, for this reason they have been calculated using a 3D finite element model. To limit rotor loss we then used a non-conductive retaining sleeve (heat shrink sleeve). In the winding, we used bar-wound conductors, which is an original winding technology developed in our laboratory, and whose advantage among others is the unusual copper fill factor that reaches almost 90%.Subsequently, we explored the high frequency machines (>1 kHz) in order to increase the power-to-weight ratio (cross the threshold of 2.5 kW/kg). We proposed, the following to the analytical and finite element study, a first conventional prototype with a power-to-weight ratio equal to 4.5 kW/kg with: FeCo stator (Vacodur49 0.2 mm), FeSi rotor and NdFeB magnets (N35EH), operated at 1666 Hz, 5000 RPM and 94% efficiency at full load. A second motor had been also proposed with both rotor and winding in aluminum, in this case the power-to-weight ratio reaches around 6 kW with, however, less efficiency (93%).Finally, this HF motor was tested, at no load, on the aforementioned test bench. The experiments were carried out on a multitude of FeCo and FeSi stator core samples coming from different manufacturing processes (insulation: bonding varnish and C-5 varnish; cutting: laser and EDM “Electrical Discharge Machining”; thermal treatment) in real operating conditions of a high frequency PM machine in order to experimentally obtain the famous “additional coefficient” of iron losses (Kadd).

Il potere di controllare l’attività dei lavoratori subordinati è da sempre una manifestazione ineliminabile della posizione giuridica del datore di lavoro. Nella misura in cui risulta necessario alla corretta esecuzione del contratto, l’assoggettamento del lavoratore al controllo datoriale costituisce una componente essenziale del rapporto di cui all’art. 2094 c.c., contribuendo a definire la nozione stessa di subordinazione. Proprio per questa ragione, una precisa ricognizione dei limiti posti dall’ordinamento ai controlli dell’imprenditore assume fondamentale importanza, onde scongiurare il rischio che la relazione che si instaura nei luoghi di lavoro divenga occasione di condizionamenti della libertà del lavoratore, incompatibili con i principi su cui si fonda una società democratica. Prendendo le mosse da tali considerazioni, l’opera analizza il quadro normativo sul potere di controllo del datore di lavoro, concentrandosi soprattutto sulle regole sancite dallo Statuto dei lavoratori e sulla più recente disciplina di protezione dei dati personali. Nei quattro capitoli lungo i quali si articola, la riflessione viene svolta con sguardo rivolto sia ai tradizionali problemi della materia sia alle nuove sfide sollevate dall’innovazione tecnologica. / The power to control the activity of workers has always been an ineradicable manifestation of the employer’s legal position. To the extent that it is necessary for the correct performance of the contract, the subjection of the worker to the employer control is an essential element of the relationship referred to in Article 2094 of the Italian Civil Code and plays a crucial role in the definition of subordination. For this reason, an accurate recognition of the legal limits on the entrepreneur’s controls is important to avoid the risk that the employment relationship becomes an occasion for conditioning workers’ freedom in a way that is incompatible with the principles of a democratic society. Based on these considerations, the study analyzes the regulatory framework on the employer’s power to control workers, focusing mostly on the rules laid down by Legge no. 300/1970 (Statuto dei lavoratori) and on the recent Personal Data Protection Regulation. The reflection, which is organized around four chapters, is carried out with an eye on both traditional problems related to this topic and new challenges raised by technological innovation.
