O programa nuclear brasileiro, materializado pelo do Acordo com a Alemanha, é o objeto do presente trabalho. O programa foi um dos grandes projetos do governo Geisel (1974-79), inserido em um conjunto mais amplo de investimentos que representava uma resposta à crise deflagrada pelo choque de petróleo de 1973 e que pretendia mudar a orientação do desenvolvimento brasileiro. Mostrando que o debate sobre a questão nuclear sempre esteve ligado à discussão sobre os caminhos para o desenvolvimento nacional, a pesquisa investiga o programa nuclear como parte integrante do II Plano Nacional de Desenvolvimento (1975-1979), proposto pelo governo Geisel. Ao lado de outros grandes projetos energéticos e de setores básicos da indústria, o programa nuclear contribuiria para impulsionar o crescimento brasileiro, alçar o desenvolvimento nacional a novo patamar e reduzir de modo significativo a dependência externa. Na primeira parte o trabalho debruça-se sobre as motivações e a racionalidade do programa, depois de uma recapitulação dos seus antecedentes e das negociações que resultaram no Acordo. A ideia difusa que os vários atores acalentaram por mais de um quarto de século materializou-se como um programa que inicialmente gerou grande entusiasmo. Aprovado por unanimidade pelo Congresso em 1975, três anos depois o programa era objeto de uma Comissão Parlamentar de Inquérito aberta no Senado. Para compreender por que e como atores específicos, centrais para o programa, abandonaram o entusiasmo e deixaram em curto intervalo de tempo de apoiá-lo, a segunda parte da pesquisa dedica-se à análise de três atores relevantes: os empresários, sobretudo os do setor de equipamentos pesados, que seriam beneficiados por um grande pacote de encomendas; os dois segmentos da burocracia estatal diretamente afeitos ao programa, os nucleocratas e o segmento mais tradicional do setor elétrico; e os cientistas, titulares históricos do tema, secundarizados pelo programa. / The Brazilian Nuclear Program, brought into being by the Brazil-Germany Nuclear Agreement, is the object of this study. The program was one of the great projects of the Geisel administration (1974-1979), within a wider set of investments that comprised a reply to the crisis triggered by the 1973 oil shock and aimed to change the direction of Brazilian development. Showing how the debate on the nuclear question was always closely linked to the discussion as to the paths of national development, the present work investigates the nuclear program as an integral part of the II Plano Nacional de Desenvolvimento (2nd National Development Plan), proposed by the Geisel administration. Alongside other major energy projects and projects directed towards basic industrial sectors, the nuclear program contributed to boost Brazilian growth, to raise national development to a new level and significantly reduce dependence on external sources. In the first part of this work, we discuss the motivations and rationale of this program, after a review of its history and of the negotiations that resulted in the Agreement. The vague idea that various actors entertained for more than a quarter of a century took shape as a project within the new national development plan. This project initially generated widespread enthusiasm. In order to understand why and how specific actors, central to the program, became disenchanted and, in a short period of time, withdrew their support, the second part of this work is dedicated to the analysis of three relevant actors: the business sector linked to heavy equipment, who would have benefitted from a large amount of orders; the two segments of state bureaucracy more directly linked to the program (the nucleocrats) and the more traditional ones from the electricity sector; and finally, the scientists, historical leaders of the initiative, relegated to second place by the program. By recognizing that the nuclear program is linked to an uncommon industrial sector, characterized by high industrial and technological complexity, this work discusses the reasons for its failure and endeavours to acquire insights into the process of constructing public policies and the requirements for their efficacy.

We try to identify which resistance practices were developed by these teachers and understand if they were organized in the individual sphere, as isolated actions of some teachers, or collectively, as an organization of professional category. Beyond that, we are also interested in investigating if this resistance had used the teacher profession as a support, being performed through pedagogical practices, or if it occurred outside the school environment, not presenting a relation, therefore, with the teaching activity. To treat our research object, we used two methodological strategies, which are oral history and documental research. For the realization of oral history, were previously selected eleven teachers who had lectured in primary or secondary school during the civil-military dictatorship. Of this total, six were located and four agreed to participated of the research. We conducted semi-structured interviews, using a predefined questionnaire as a guide, in order to know memories of the participants about the researched topic. The documental research was realized in the collection of the Departamento Estadual de Ordem Política e Social (DEOPS/SP), in order to find documents produced by this politics police organ about the studied teachers. We attribute great relevance to the oral sources obtained, due the possibility they represent of understanding our object of study from the point of view of the involved, i.e., the teachers. This research did not seek to be generalizing, since we do not work with samples, but with specific cases. In the analysis of collected sources, were constructed thematic axes which address different resistance practices developed by the focused teachers and the repression suffered by their actions. These axes are: "Presentation of teachers"; "resistance through the profession: possibilities and limits"; "resistance out of school" and "repression." As result, it can be seen that the participants built, through various practices, resistance to the military regime. Moreover, the opposition performed by these teachers was bounded by the characteristics of the opposition movement of society in general, i.e., the resistance developed by them was integrated into the social and political context in which the country was in each period of civil-military dictatorship. / Esse é um estudo sobre a resistência de professores de primeiro e segundo graus ao regime militar brasileiro. Buscamos identificar quais as práticas de resistência desenvolvidas por tais docentes e compreender se elas foram organizadas na esfera individual, como ações isoladas de alguns professores, ou coletiva, como organização da categoria profissional. Além disso, interessa-nos investigar também se essa resistência utilizou a profissão professor como suporte, sendo realizada por meio das práticas pedagógicas, ou se ocorreu fora do ambiente escolar, não apresentando ligação, portanto, com a atividade docente. Para tratar de nosso objeto de pesquisa, utilizamos duas estratégias metodológicas, quais sejam a história oral e a pesquisa documental. Para a realização da história oral, foram previamente selecionados onze professores que lecionavam no ensino de primeiro ou segundo grau durante a ditadura civil-militar. Desse total, seis foram localizados e quatro aceitaram participar da pesquisa. Realizamos entrevistas semi-estruturadas, utilizando um questionário pré-definido como guia, a fim de conhecer as memórias dos participantes acerca do tema pesquisado. A pesquisa documental foi realizada no acervo do Departamento Estadual de Ordem Política e Social (DEOPS/SP), a fim de localizar documentos produzidos por esse órgão de polícia política sobre os professores estudados. Atribuímos grande relevância às fontes orais obtidas, devido à possibilidade que elas representam de compreender nosso objeto de estudo a partir do ponto de vista dos próprios envolvidos, ou seja, dos professores. A pesquisa não procurou ser generalizante, uma vez que não trabalhamos com amostragens, mas sim com casos específicos. Nas análises das fontes coletadas, foram construídos eixos temáticos que abordam as diferentes práticas de resistência desenvolvidas pelos professores focalizados e a repressão sofrida por suas ações. Estes eixos são: apresentação dos professores ; resistência através da profissão: possibilidades e limites ; resistência fora da escola e repressão . Como resultados, pode-se constatar que os participantes construíram, através de práticas diversas, a resistência ao regime militar. Além disso, a oposição realizada por esses professores foi delimitada pelas características do movimento oposicionista da sociedade em geral, ou seja, a resistência por eles desenvolvida estava integrada no contexto social e político pelo qual o país passava em cada período da ditadura civil-militar.

This research was accomplished with students in a class of 1 st year hight school that were applied in four games as a teaching and learning strategy. In the first game, was scheduled activities for the student to recognize the different representations of functions such as: writing; the numeric form, expressed through tables; visual, expressed by means of graphs; algebraic, represented by formulas; and using these differents representations to clarify the concept of function. In the second game, were developed different problem situations on polynomial function of the 1st degree. In the third game, was scheduled activities on the polynomial function of the 2nd degree and in the fourth game, were presented problem situations involving polynomial function of the 2nd degree in order to explore its properties. The research foccus is qualitative and the data analysis and interpretation of results were based on the theoretical and research objectives. The modality used for the research was the field search because data collection was carried out by the teacher and researcher through observations of students strategy during the games, noted in her field diary, and reports and work performed by them. From the results obtained we can concluded that the game was a good teaching strategy and facilitated the undestanding of the content worked. / Este trabalho teve como objetivo verificar se a utilização dos jogos como estratégia de ensino facilitou a aprendizagem dos alunos referente ao conceito de função e de funções polinomiais do 1º e do 2º graus. Esta pesquisa foi realizada com alunos de uma turma do 1º ano do Ensino Médio em que foram aplicados quatro jogos como estratégia de ensino e aprendizagem. No primeiro jogo, foram programadas atividades para o aluno reconhecer as diferentes representações de funções, tais como: a forma escrita; a forma numérica, expressa por meio de tabelas; visual, expressa por meio de gráficos; algébrica, representada por meio de fórmulas e que utilizasse essas diferentes representações para tornar mais claro o conceito de função. No segundo jogo, foram elaboradas diferentes situações-problema sobre a função polinomial de 1° grau. No terceiro jogo, foram programadas atividades sobre a função polinomial de 2º grau e, no quarto jogo, foram apresentadas situações-problema envolvendo a função polinomial do 2º grau com o propósito de explorar suas propriedades. A pesquisa teve uma abordagem qualitativa e a análise dos dados e a interpretação dos resultados foi embasada no referencial teórico e nos objetivos da pesquisa. A modalidade da pesquisa foi a de campo, pois a coleta de dados foi realizada pela professora e pesquisadora através das observações das estratégias dos alunos durante os jogos, anotadas em seu diário de campo, e dos trabalhos e relatos por eles realizados.

O 'Projeto Etanol de 2ª Geração', etanol produzido a partir de biomassas lignocelulósicas, aqui selecionado para estudo de caso, foi extraído da carteira de projetos do Centro de Tecnologia Canavieira (CTC). O método estruturado sugerido é constituído, fundamentalmente, por oito requisitos arranjados de forma cronológica ao longo do desenvolvimento do projeto, que visam auxiliar na prospecção, entendimento, avaliação, valoração, priorização, planejamento e implantação de, por exemplo, uma tecnologia inovadora, otimizando tempo, capital e recursos humanos aplicados. Um dos principais pontos do método proposto refere-se à escolha adequada das ferramentas gerenciais a serem utilizadas em cada requisito (brainstorm, análise de patentes, painel de especialistas, análise SWOT, dentre outras). O êxito na aplicação do método requer o entendimento de todos os (potenciais) efeitos, inclusive os colaterais, no processo como um todo. Ou seja, uma vez que toda ferramenta gerencial apresenta pontos fortes e fracos, o importante é adaptá-las ao sistema de negócio e não vice-versa. A partir do gerenciamento do projeto por um gestor com domínio das ferramentas gerenciais, a escolha destas ocorre de forma dinâmica, onde a cada passo de avaliação novas ferramentas (simples e/ou complexas) podem ser incluídas ou excluídas da matriz do método. Neste trabalho ficou demonstrada a importância de se trabalhar com métodos estruturados e flexíveis, que permitem retroalimentação de informações geradas internamente durante o desenvolvimento da pesquisa ou advindas de fontes externas. O projeto Etanol de 2ª Geração do CTC vem aplicando o método proposto em seu desenvolvimento e obtendo grande êxito em seus resultados, uma vez que a equipe envolvida permanece focada no objetivo principal, obedecendo prazos e recursos inicialmente definidos, com constância do propósito do projeto, sem retrocesso ou recomeço. / The objective of this work was to propose a method, structured and supported by management tools, to guide and systematize the development of a project of research focusing to deploy a new technology in the market. The '2nd Generation Ethanol Project', ethanol produced from lignocellulosic biomass, was selected as case study from the portfolio of projects of the Sugarcane Technology Center. Fundamentally, the suggested structured method consists of eight requirements arranged in a chronological order throughout the project development cycle, aiming at assisting the exploration, understanding, evaluation, assessment, prioritization, planning and deployment of, for example, an innovative technology, optimizing the applied time and capital and human resources. One of the main points of the proposed method refers to the adequate choice of the management tools to be used in each requirement (brainstorm, patent analysis, expert panel, SWOT analysis, among others). The successful application of the method requires the understanding of all (potential) effects, including the side effects, in the whole process. Since all management tools have strong and weak points, the most important thing is to adapt them to the business system and not vice versa. Considering that the project should be conducted by a person with some knowledge and skilled on this area, the choice of the tools happens in a very dynamic way, where after each assessment, new tools (simple and/or complex) may be included or excluded from the method matrix. In this work it was demonstrated the importance of working with structured and flexible methods which accept retrofitting of information generated along the research development or that comes from external sources. The 2nd Generation Ethanol Project has internally used the proposed method and obtained good results, since with this approach it was possible to keep the team focused on the same main goal, obeying the planned schedule with the resources initially defined, with no rewind or restart.

En analysant le matériel provenant d’une région montagneuse qui s’étend au nord de l’Iran, nous étudions les sociétés locales de l’âge du Fer (fin du IIe - fin du Ier millénaire avant J.C.). Bien que l’on ait déjà noté les particularités de la culture matérielle de l’Iran septentrional par, il n’existe guère d’études synthétiques sur la culture matérielle, sa chronologie, et les représentations des sociétés qu’elles permettentNous utilisons des données anciennes, les unes publiées les autres inédites, et des données nouvelles : nous avons étudié les unes et les autres en Iran et au Japon. Quatre sujets sont traités : l’élaboration de la chronologie, la diversité régionale des céramiques, l’évolution des pratiques, et la distribution des sites.En nous fondant sur les résultats de ces analyses et sur le cadre méthodologique et les hypothèses de travail de l’ethnologie, de l’ethnoarchéologie et de la sociologie, nous tentons d’interpréter les céramiques particulières et les pratiques funéraires, qui sont considérés comme représentatifs de la culture matérielle de l’Iran septentrional, comme l’organisation sociale qui a permis d’organiser les relations entre les populations qui menaient une vie dispersée et fluide selon des conditions géographiques variées. On observe que l’organisation sociale n’a pas structuré la société locale de manière stable. Dans la deuxième moitié de l’âge du Fer, on peut considérer qu’avec la pénétration du nouvel ordre symbolique, la société locale qui vivait dans des conditions naturelles variées, les modes d’occupation ont évolué, ainsi que les traditions techniques. En même temps, avec l’évolution des pratiques funéraires vers la simplicité, les pratiques autour du bâtiment collectif se sont propagées dans l’espace de la région. Dans l’Iran septentrional, l’âge du Fer correspond historiquement à l’époque de ces évolutions structurelles des sociétés locales. / Analyzing the material from a mountainous region of northern Iran, we investigate the image of a local society during the Iron Age (Late 2nd - late 1st millennium B.C.). Although the peculiarities of the material culture of that region have been recognized since long, there are not enough comprehensive studies on the material culture, chronology, and precise representations of the societies.For this purpose, we deal with old data, some published other unpublished, as well as new material including a lot of unpublished ones that we have studied in Iran and Japan. Four main topics are treated: chronology, change and regional diversity of pottery, evolution of practices, and distribution of sites. Based on the results of these analyses and on the methodological framework and working hypotheses deriving from the results of ethnology, ethno-archaeology and sociology, we try to interpret the peculiar ceramics and the funerary practices, which are considered as representative of the material culture of Northern Iran, as well as the social organization which permitted to maintain the relationship between the populations who fluidly and dispersed lived in that area which presents various geographic conditions. Finally, one concludes that the social organization did not structure in local society in a stable manner.In the second half of the Iron Age, we can consider that, with the penetration of the new symbolic order, the local society which lived under varied natural conditions, modes of occupation and habitation and technical traditions have changed. During the same period, with the evolution of funeral practices towards simplicity, practices in public spaces and buildings extended over the region. In northern Iran, the Iron Age historically corresponds to the time of these structural changes in local society.

Cette thèse de sociologie cherche à montrer la relation ambivalente que des personnes handicapées visuelles, aveugles ou malvoyantes, nouent avec leur agglomération, ici l’agglomération chambérienne. Dans un premier temps, elle montre que l’espace urbain est pour ces personnes handicapées un espace de fermeture : sa lecture, sa connaissance, son utilisation sont restreintes,  soumises à des impératifs comme la canne, la technique de locomotion, l’utilisation d’outils mis à leur intention dans la ville. La vie dans l’espace privé n’échappe à de multiples contraintes. La perte de vue malmène la sécurité ontologique, altérée par la souffrance et souvent la solitude. Et pourtant, l’espace urbain est l’espace où les personnes handicapées visuelles peuvent vivre et se déplacer en autonomie. Cette autonomie est l’œuvre de deux types d’acteurs : d’une part la ville, qui réalise les aménagements urbains d’accessibilité, des chaines d’accessibilité prévus par la loi, parfois antérieurement à la loi, comme c’est le cas de la ville de Chambéry, récompensée pour son action en faveur des personnes handicapées et d’autre part les personnes handicapées elles-mêmes qui doivent conquérir leur autonomie au prix d’un travail personnel exigeant. ‘’Il faut apprendre mon métier le personne handicapée’’, a dit l’une des personnes interviewées. La conquête de son autonomie s’apparente au ‘’cas de la chose réelle’’. Cette conquête ne considère pas seulement le côté environnemental et situationnel du handicap, mais place la personne aveugle ou malvoyante dans une spécificité vis à vis de l’espace urbain. L’extension à l’analyse sociologique de la théorie écologique de Gibson relative à la perception propose de considérer les personnes handicapées visuelles dans une relation spécifique avec l’espace urbain, qui évoque le concept de niche écologique. / This thesis in sociology aims at describing the ambivalent relationship that visually impaired persons, whether they are blind or partially sighted, develop with their urban area, here that of Chambery.First, it shows that, for these disabled persons, urban space is a space where they feel locked in : the reading, the knowledge, the use of this space are restricted, submitted to imperatives such as the walking stick, the locomotion technique, the use of tools provided for them by the city. Living in the private space is also subject to many constraints. The loss of eyesight reduces ontological safety, which is altered by pain and often by loneliness.And yet urban space is the space where visually impaired persons can live and move self- autonomously. Their autonomy is made possible by two actors: on the one hand, the city which carries out urban improvements in its accessibility to conform to the law- sometimes even before the bill was passed as is the case with the city of Chambery which was rewarded for its achievements in favour of disabled persons ; on the other hand, the disabled persons themselves who need to conquer their autonomy at the expense of demanding personal efforts. “ I have to learn my job as a disabled person”, said one of them in an interview. Conquering one’s autonomy shows similarities to ‘’the real-life situation’’…. This conquest not only takes into account the environmental and situational aspect of the handicap, but it also places the blind or partially impaired person in a specific position with regard to urban space. An extension to the sociological analysis of Gibson’s ecological theory relating to perception proposes to consider visually impaired persons in a specific relationship with urban space, conjuring up the concept of ecological niche.
