Noël-Bouton, Rollet Véronique. "Amaury-Duval (1808-1885) : l'homme et l'oeuvre". Paris 4, 2007. http://www.theses.fr/2006PA040137.
Texto completoResumen
La présente étude se veut complémentaire aux précédentes publications dont Amaury-Duval a été l’objet : le catalogue des expositions de Montrouge et Brest (1974) et la réédition annotée et commentée par Daniel Ternois de son ouvrage L’Atelier d’Ingres (Arthéna 1993). De nouvelles informations proviennent de diverses sources d’archives privées ainsi que de l’important fonds conservé par la Société éduenne (Autun). Une première partie présente la biographie de l’artiste en s’attardant sur son entourage familial dont le talent, l’ouverture d’esprit et la curiosité orientèrent les choix de l’artiste et influencèrent sa vie entière. Un passage est consacré à l’atelier du peintre ainsi qu’à ses principaux élèves. Le catalogue de l’œuvre est organisé en deux parties, la première étant consacrée aux portraits dont Amaury-Duval s’était fait une spécialité comme son maître Ingres. Les autres sujets sont regroupés ensuite. La peinture religieuse y tient une bonne place. Les pièces annexes jointes à l’exposé sont un complément indispensable. Outre les textes habituels (chronologie, bibliographie, catalogues d’expositions…), elles comportent la copie de plusieurs manuscrits inédits importantsThis study wants to complete the researches about Amaury-Duval : catalogues of the exhibitions held in Montrouge and Best (1974) and the new edition of l’Atelier d’Ingres by Daniel Ternois (Arthéna, 1993). The first part offers the artist biography with a short of his family whose memebers were interested in everything in art and culture. Many of them had a great influence over the artist for all his live. A short part is dedicated to his study and his pupils. The catalogue has two parts, the first one contains portraits. Amaury-Duval made many of them an dit is in this genre, he is the nearest of his teacher Ingres. Other subjects come after. About them the religious paintings are important. The Annexes are a main point. They contain the usual textes (chronology, bibliography, exhibitions catalogues…) and several unpublished manuscripts

Texto completoResumen
Quand il arrive au pouvoir le 22 septembre 1957, François Duvalier, noiriste et nationaliste, découvre que les acteurs internationaux influencent considérablement la politique intérieure d' Haïti. Il décide alors de s'en servir à ses propres fins pendant ses quatorze années à la présidence. Cette thèse analyse la manière dont le président « à vie» de la République d'Haïti, internationalement connu sous le nom de Papa Doc, prenant en compte les forces profondes et le contexte de la guerre froide, met en application sa vision du monde et sa conception des relations internationales. Il parvient à obtenir du Vatican la nationalisation du c1ergé catholique, contrer les menaces et tentatives d'invasions venant de la République Dominicaine et de Cuba, faire jouer sa prétendue amitié avec Charles de Gaule, utiliser constamment la menace communiste pour obtenir l'aide des Etats-Unis dans l'unique objectif de se maintenir perpétuellement au pouvoir.

Texto completoResumen
Cette étude porte sur les impacts géomorphologiques de la crue extrême de la rivière Duval, qui s’est produite en juin 2008, dans la communauté de Pangnirtung au Nunavut. L’action combinée de l’érosion mécanique et thermique (thermo-érosion) du puissant torrent a rapidement causé l’érosion de 90 000 m3 de pergélisol près de l’embouchure de la rivière, endommageant de façon permanente les deux ponts situés au centre de la communauté. Un événement d’une telle envergure a soulevé de nombreuses inquiétudes dans la communauté notamment en ce qui a trait à la pérennité des infrastructures routières et résidentielles, à la sécurité des habitants ainsi qu’au risque de récurrence d’une telle crue. Cette étude a pour objet de quantifier les facteurs qui contribuent au processus à savoir, la température de l’eau, le débit fluvial, la température du pergélisol et sa teneur en glace et d’intégrer leur impact combiné dans une analyse numérique afin de mieux cerner les conditions dans lesquelles l’événement catastrophique s’est produit, d’évaluer les risques de récurrence d’une telle crue et de déterminer le degré de susceptibilité du cône alluvial de Pangnirtung face au processus d'érosion fluviale et de la thermo-érosion.

Pierre, Wilkenson Fleuricour. "La conception de la propriété foncière en Haïti de 1804 à 1986". Toulouse 1, 2010. http://www.theses.fr/2010TOU10020.
Texto completoResumen
Les biens ont toujours occupé une place importante dans la vie des sociétés. Leur distribution, leur usage, leur acquisition, leur transmission reflètent profondément la conception que s'en font une société. Ainsi, à travers ce travail nous avons constaté que l'avènement de la République d'Haïti en 1804 et jusqu'en 1986 au départ du président Jean-Claude DUVALIER, ce pays a été traversé par deux conceptions de la propriété foncière. La première que l'on peut qualifier de militaro-néopotique est hérité de Toussaint LOUVERTURE et s'étend de 1804 à 1843. La seconde qui est fondée sur le mythe de la propriété foncière pour tous va de 1843 à 1986. Cependant, il a été constaté que de 1804 à 1986 les petits cultivateurs se sont toujours battus pour avoir droit à une jouissance paisible du lopin de terre qu'ils exploitaient. Ce qui n'a pas toujours été facile puisque les proches des divers gouvernements ont eu une conception différente de la propriété foncière et de l'exploitation des biens fonciers. L'opposition de ces deux visions a souvent été la source des conflits et des soulèvements armés en Haïti. Bien plus, cette lutte entre les différents groupes sociaux a plongé le pays dans une instabilité chronique et y a engendré l'insécurité, le chômage et la pauvretéProperty has always occupied a place in the life of societies. Distribution (especially land, their use, acquisition) transmitted reflect deep design that makes it a society. Thus, through this work we found that the accession of the Republic of Haïti in 1804 and until 1986 (departure of president Jean-Claude DUVALIER), the country was crossed by two concepts of land ownership. The first one can be described as military crony is inherited from Toussaint LOUVERTURE, and extends from 1804 to 1843. The second can be described in the myth of the land all of 1843 to 1986. However, it was found that from 1804 to 1986 small farmes have always fougth for the right to peaceful enjoyment of the plot of land the farm. This was not always easy because the relatives of different gouvernments have had a vision different ownership and exploitation of land. The opposition of these two wiews has often been the source of conflict, and armed uprisings identificate this country. More, this struggle between different social groupes plunged the country into a chronic instabilité (sic) and insecurité (sic) is created, unemployment and poverty

This study presents an analysis of pedagogical, curricular and content knowledge that teachers of mathematics in basic education, in Ponta Grossa/PR have on Trigonometry. Empirical data was obtained with the use of a tool containing different kinds of errors made by students in Trigonometry exercises to be analyzed and point out possible intervention by the teachers as well as to present responses to Trigonometry concepts. This data was analyzed based on Shulman’s (1986,2001) theoretical contributions and on the functions and discursive operations according to the Register of Semiotic Representation theory by Raymond Duval (2004, 2009, 2011). The research question was: How is knowledge about Trigonometry characterized and what is the nature of the knowledge related to learning issues and Trigonometry teaching presented by mathematics teachers who work in basic education? And the objectives of the study were: to characterize the knowledge of Trigonometry of mathematics teachers working in basic education and; to reveal the nature of mathematics teachers’ knowledge in relation to Trigonometry learning and teaching issues.The research had a qualitative approach, with descriptive and elucidative characteristics, and the analysis methodological procedures were assisted by Bardin’s (2009) content analysis. The organization of data was carried out with the aid of the software Atlas.ti, through which the subject content knowledge, the pedagogical knowledge of content, and the curricular knowledge were gathered within the discourse expansion function proposed by Duval (2004) for later analysis. The results of this study indicate that teachers’ knowledge that was more evident was the knowledge of the subject content. These results point to the need for teachers to be more attentive to other aspects of knowledge also necessary to their education practice and which seem to have been disregarded.
Este trabalho apresenta uma análise dos conhecimentos pedagógicos, curricular e de conteúdo de professores de matemática da Educação Básica, do município de Ponta Grossa/PR, sobre Trigonometria. Os dados empíricos foram obtidos por meio da aplicação de um instrumento contendo diferentes tipos de erros cometidos pelos alunos em atividades de Trigonometria, para a análise e apontamento de possíveis intervenções pedagógicas pelos professores e também respostas a conceitos de Trigonometria. Esses dados foram analisados tendo por subsídios teóricos as contribuições de Shulman (1986, 2001) e as funções e operações discursivas apresentadas na teoria dos Registros de Representação Semiótica segundo Raymond Duval (2004, 2009, 2011). O problema de pesquisa que se buscou responder foi: Como se caracterizam os conhecimentos sobre Trigonometria e qual a natureza dos conhecimentos relativos a questões sobre a aprendizagem e o ensino de Trigonometria apresentados por professores de matemática que atuam na Educação Básica? A partir disso os objetivos da pesquisa foram: caracterizar os conhecimentos sobre Trigonometria apresentados por professores de matemática que atuam na Educação Básica e; desvelar a natureza desses conhecimentos dos professores de matemática em relação a questões sobre o ensino e a aprendizagem da Trigonometria. Para a realização da pesquisa foi adotada a abordagem qualitativa, de cunho descritivo e explicativo, com os procedimentos metodológicos de análise sustentados pela análise de conteúdo de Bardin (2009). A organização dos dados contou com o auxílio do software Atlas.ti por meio do qual foram elencados o conhecimento de conteúdo da matéria, o conhecimento pedagógico de conteúdo e o conhecimento curricular e as funções de expansão dos discursos propostas por Duval (2004), para posterior análise. Os resultados dessa pesquisa indicam que os conhecimentos docentes que se sobressaíram foram os conhecimentos de conteúdo da matéria a ser ensinada. Esses resultados apontam para a necessidade de um olhar mais atento pelos professores sobre os demais saberes necessários à prática educativa e que parecem não estarem sendo postos em prática.

The dissertation presents an analysis of teacher s textbooks, adopted in public schools in a city in Minas Gerais, focusing on the elaboration of the concept of multiplication from the 1st to 5th year of elementary school. The qualitative analysis about 16 multiplication activities, the most part divided in about four tasks, was developed by the match between the National Curriculum Parameters - PCNs, adopted as guidelines by the investigated textbooks and the Theory of Raymond Duval. As a result, we obtained that most of the initial activities involves conversion. Among the other tasks of the activity involves at least one treatment. We also found an activity involving only treatment, and only three activities without tasks involving treatment. Still, we had a proposal in the guidelines to the teacher, promoting conversion in both directions for proper coordination of semiotic representation registers. Most used registers are mixed, involving the numerical record with natural language
A dissertação apresenta uma análise dos Livros da Coleção do Professor, adotados na rede municipal de uma cidade de Minas Gerais, focalizando o processo de elaboração do conceito de multiplicação do 1° ao 5° ano do Ensino Fundamental. A análise, de caráter qualitativo, sobre 16 atividades de multiplicação, subdivididas em cerca de quatro tarefas, em sua maior parte, desenvolveu-se mediante o pareamento entre os Parâmetros Curriculares Nacionais PCNs, adotados como diretrizes no município e a Teoria de Raymond Duval. Como resultados, obtivemos que maior parte das atividades iniciais envolve conversão. Dentre as demais tarefas da atividade ao menos uma envolve tratamento. Encontramos também uma atividade envolvendo apenas tratamento, e apenas três atividades sem tarefas envolvendo tratamento. Ainda, obtivemos uma proposta nas orientações ao professor, promovendo conversão em dois sentidos, para a devida coordenação de registros de representação semiótica. A maior parte dos registros utilizados é misto, envolvendo o registro numérico com o da língua natural

The hypothesis that there is no significant difference between the mean SAT Total Reading Battery percentile scores of LEP students who are mainstreamed and those who are self-contained, was studied. Sixty-eight fourth, fifth, and sixth-grade LEP students were administered the SAT. They were divided into two groups. The self-contained group consisted of 35 students; the mainstreamed group consisted of 33 students. The mean percentile score for the mainstreamed group was 39.57 with a standard deviation of 21.02. For the self-contained group, the mean was 26.0 and the standard deviation was 18.53. The computed t = 2.67, P < .05. The null hypothesis was rejected.

This thesis aimed to investigate how blind students visualize geometric objects, based on the Theory of Semiotics Representation, Vision and View Registers of Raymond Duval. Checking the official documents that determine the course of education, we found that they establish that children and young people with special educational needs must have access to schools, preferably in the regular school system, which must be suitable to them, both materially and educationally. So, we performed a case study in a public school in the city of Santo André, São Paulo, which has blind students attending ordinary classrooms. Through interviews, we investigated how congenitally blind students recognize and work with representations of geometric objects and what are the possibilities of these students create their own representations on paper. We found that the interviewed students identified flat geometric figures embossed on paper, recognizing their forms, but didn t recognize the geometric solids representations in perspective, because the outline of these objects does not match with their outline on paper. We note the need to teach how to visualize, it is necessary that the blind students learn how to identify the represented object in each representation, this recognition is not automatic but it can be learned. We noted that the order of perception by touching is different when the blind student has a concrete object in his hands and when it has a representation of this object embossed on paper. When the blind student has a concrete object in his hands, and this object is familiar to him, he recognizes the entire object without the need to observe the parts, but when the representation is embossed on paper, even if the student knows the represented object, he visualizes the parts first and then the entire object. In the interviews, we witnessed times when the students reached the perceptual, operative and discursive apprehensions, despite having a very limited repertoire of geometric terms. One of the students operated the dimensional deconstruction of the forms and could "see" mathematically, as mentioned by Duval (2011). None of the students we interviewed had ever built or designed geometric figures in a way that after they could recognize them, so the sequential apprehension that aims at the construction of geometric figures was not observed during our investigation. Seeking to fill this gap, we propose the creation of the Drawing on Positive Relief Clipboard, with which a blind student has the possibility to design and feel the design embossed on paper
Esta tese teve por objetivo investigar como alunos cegos visualizam objetos geométricos, embasada na Teoria dos Registros de Representação Semiótica, Visão e Visualização de Raymond Duval. Verificando os documentos oficiais que determinam os rumos da educação, constatamos que eles estabelecem que as crianças e jovens com necessidades educacionais especiais devem ter acesso às escolas, preferencialmente na rede regular de ensino, que devem estar adequadas a eles, tanto material quanto pedagogicamente. Nesse sentido, realizamos um estudo de caso em uma escola pública estadual da cidade de Santo André, São Paulo, que tem alunos cegos frequentando as salas de aula comuns. Por meio de entrevistas, investigamos como alunos cegos congênitos reconhecem e trabalham com representações de objetos geométricos e quais as possibilidades desse aluno criar suas próprias representações no papel. Verificamos que os alunos entrevistados identificaram figuras geométricas planas, representadas em relevo, no papel, reconhecendo suas formas, mas não reconheceram representações de sólidos geométricos em perspectiva, pois o contorno desses objetos não corresponde ao contorno de sua representação no papel. Constatamos a necessidade de ensinar a visualizar, é preciso que o aluno cego aprenda a identificar em cada representação o objeto representado, esse reconhecimento não é automático, mas pode ser aprendido. Observamos que a ordem de percepção pelo tato é diferente quando o aluno cego tem um objeto concreto em suas mãos e quando tem uma representação deste objeto em relevo no papel. Quando o aluno cego tem um objeto concreto em suas mãos, e este objeto lhe é familiar, ele reconhece o todo, sem necessidade de observar as partes, mas, quando a representação está em relevo no papel, mesmo que o aluno conheça o objeto representado, ele visualiza primeiro as partes para depois visualizar o todo. Nas entrevistas, presenciamos momentos em que alunos atingiram as apreensões perceptiva, operatória e discursiva, apesar de apresentarem um repertório muito limitado de termos geométricos. Um dos alunos operou a desconstrução dimensional das formas e pôde ver matematicamente, como mencionado por Duval (2011). Nenhum dos alunos que entrevistamos já havia construído ou desenhado figuras geométricas de forma que pudesse reconhecê-las, portanto, a apreensão sequencial, que tem por objetivo a construção de figuras geométricas, não foi observada durante nossa investigação. Procurando preencher essa lacuna, propomos a criação da Prancheta de Desenho em Relevo Positiva, com a qual um aluno cego tem a possibilidade de desenhar e sentir o desenho em relevo no papel

Power transformers are essential equipment in eletric systems. Considered as highly expensive equipment it requires greater attention regarding the occurrence of failures. A failure on equipment can cause serious trouble to the concessionaire responsible for the generation, transmission and distribution of energy. In the present scenario, where legislation has increased the severity with which oversees these failures and demanding a higher efficiency of the same, it is necessary to create appropriate policies to investigas possible equipment failure. These failures can be caused by several factors, among them, the gases dissolved in the oil due to its degeneration. One of the most used techniques for the diagnosis of power transformers from these dissolved gases is the Duval Triangle, a method that has a precision and considerably high reliability. However, for proper planning of maintenance, avoiding a possible sudden withdrawal and supply cut, it is necessary to provide further information, including a quantitative analysis of the causes of failure and a history of the evolution of the operating status of the machine. To this end it is proposed to use a fuzzy logic by the method of Duval to provide an analysis of the transitions between the diagnostic originally presented to enable monitor the level of relevance of each possible cause for the diagnosis equipment allowing perform scheduled and preventive maintenance. The proposed methodology was validated using real data equipment in operation in the brazilian electric system.
Transformadores de potência são equipamentos essenciais em um sistema elétrico. São considerados equipamentos de alto custo que requerem uma maior atenção no que tange a ocorrência de falhas. Uma falha em um equipamento pode causar sérios prejuízos à concessionária responsável pela geração, transmissão e distribuição de energia. No cenário atual, onde a legislação vem sempre aumentado o rigor com que fiscaliza essas falhas e cobrando uma maior eficiência das mesmas, faz-se necessário criar políticas adequadas para investigas possíveis falhas nos equipamentos. Falhas essas que podem ser originadas por diversos fatores, dentre eles, pelos gases dissolvidos no óleo devido a sua degeneração. Um dos métodos mais utilizados para diagnóstico de transformadores de potência é a análise de gases dissolvidos utilizando o Triângulo de Duval, que apresenta uma precisão e confiabilidade consideravelmente altas. No entanto, para um planejamento adequado de manutenção, evitando uma possível retirada brusca do equipamento e corte no fornecimento, é necessário prover mais informações, incluindo uma análise quantitativa das causas das falhas e um histórico da evolução do estado operativo do equipamento. Para tanto propõe-se a utilização de uma lógica fuzzy junto ao método de Duval para fornecer uma análise das transições entre os diagnósticos apresentados originalmente de forma a permitir acompanhar a evolução do nível de pertinência de cada possível causa no diagnóstico do equipamento, possibilitando realizar manutenções programadas e preventivas. A metodologia proposta foi validada utilizando dados reais de equipamentos em operação no sistema slétrico brasileiro.

Leech, Donald Wayne. "Faculty Perceptions of Shared Decision Making and the Principal's Leadership Behaviors in Duval County Secondary Schools". UNF Digital Commons, 1999. http://digitalcommons.unf.edu/etd/253.
Texto completoResumen
Members of the school community should work collaboratively in the educating of students. Teachers and principals must understand that their traditional roles have changed and improved organizational teamwork will be fostered by all members of the learning community assuming decision making roles. Toward this end, the purpose of this correlational study was to explore the relationship between teachers' perceptions of the leadership behaviors of Duval County secondary school principals and their perceptions of the level of shared decision making practiced in their schools. This study provides insight into principal behaviors which nurture participation.
Leadership behavior was operationalized by the responses to each of the five practices on the Leadership Practices Inventory [LPI] (Kouzes & Posner, (1997). These behaviors were (a) challenging the process, (b) inspiring a shared vision, (c) enabling others to act, (d) modeling the way, and (e) encouraging the heart. The level of shared decision making was measured by responses to the Shared Educational Decisions Survey-Revised (Ferrara, 1994) in the areas of (a) planning, (b) policy development, (c) curriculum and instruction, (d) student achievement, (e) pupil personnel services, (f) staff development, and (g) budget management.
The population for the study was a sample selected from all secondary schools in the Duval County Public School System. Schools with principals who had served in their schools two or more years were selected for the study. The sample consisted of 646 participants from 26 schools.
Pearson product-moment correlations were generated for each of seven questions. A total of 34 significant relationships between the leadership behaviors of the principal and the level of shared decision making were identified. The significant correlations ranged between .096 and .191. These weak correlations demonstrate that the principals' leadership practices only explained between one percent and four percent of the variance in the level of shared decision making. Therefore, there was very little relationship between the leadership behaviors of the principal and the level of shared decision making in schools.
A possible explanation of the weak relationships discovered for each of the seven research questions may relate to the construct of the principals' leadership behaviors used in the study. From a more speculative perspective, individual leadership behaviors of school principals may have less influence on the decision making culture than the organizational structure and culture of the schools and school district.
The findings of this study provide implications for the leadership of school principals as they implement shared decision making in their schools. Principal training programs must provide prospective principals with experiences which will nurture the skills necessary to promote dynamic learning communities. Furthermore, in order to encourage their involvement, teachers must also be trained in this area. Tomorrow's principals must develop collaborative, professional cultures characterized by shared governance. Educational leaders should continue to construct deeper understandings of these professional learning communities.

Texto completoResumen
L'agence d'architecture parisienne de Charles Duval (1873-1937) et Emmanuel Gonse (1880-1954), créée en 1905 par ces deux anciens élèves de l'atelier Pascal à l'Ecole des Beaux-Arts, a connu une destinée bipartite consécutive aux bouleversements engendrés par la Première Guerre Mondiale. Avant 1914, à l'instar de nombreuses agences parisiennes, Duval et Gonse assoient la prospérité de leur association sur des programmes exclusivement privés issus d'une commande dont l'origine familiale ou para-familiale est fortement majoritaire. Après 1918, les deux architectes, partie prenante d'une société civile d'architectes dénommée La Cité nouvelle, qu'ils ont eux-mêmes contribué à créer, et s'appuyant sur un réseau efficace de collaborateurs locaux, se consacrent désormais de manière prédominante à la reconstruction des départements dévastés, principalement la Somme. Leur est alors dévolue, pour le compte de coopératives de reconstruction, la réédification des bâtiments communaux d'une quinzaine de villages de la région de Roye, outre cette dernière ville, et la reconstruction de nombreux immeubles privés, agricoles et industriels en cette même région. Ils orientent, par ailleurs, une partie notable de leur production dans la réalisation de centres d'hygiène maternelle et infantile, voulue par une oeuvre privée créée par Suzanne Gonse-Boas, épouse d'Emmanuel : cette spécialisation leur vaut, en 1928, la commande de leur oeuvre la plus considérable, l'Ecole de puériculture de la Faculté de médecine de Paris, qui constitue également la consécration de leur association. Déterminer les modalités du basculement qui ont fait d'une agence originellement vouée au marché immobilier parisien, l'un des cabinets les plus féconds et les plus efficaces investis sur le terrain de la Première Reconstruction, paraissait primordial tout en précisant l'adapatation des architectes, tout à la fois à une diversité de programmes inusitée et à la complexité de procédures réglementaires imposant rigueur administrative et rapidité opérationnelle. En parallèle, l'analyse des réseaux de la commande permettrait de souligner la forte obédience familiale de ce cabinet, dont la production dans le domaine sanitaire et hospitalier demeure la manifestation la plus spectaculaireThe parisian architecture office of Charles Duval (1873-1937) and Emmanuel Gonse (1880-1954), founded in 1905 by these two old boys of Pascal 's studio at the Ecole des Beaux, knew a bipartite destiny owing to the upsets engendered by the First World War. Before 1914, in accordance with many Parisian agencies, Duval and Gonse establish their patnership propsperity upon exclusively private plans born from an order about which the family or nearly family origin is a strong majority part. After 1918, the two architects, fellows of an architecture civil company, named La Cité Nouvelle, what they have themselves conduced to found, and leaning on an efficient system of local collaborators, are henceforth devoting themselves, with predominant way, to the reconstruction of devastated counties, mainly Somme country. Then they are chosen for rebuilding, on reconstruction cooperatives behalf, communal buildings in about fifteen villages of Roye's country, in adition to this small town, and the rehabilitation of many private, agricultural and industrial, buildings in the same region. They are leading otherwise, a notable part of their designing to the achievement of maternal and infantile hygiene dispensaries, deliberated by a private foundation created by Suzanne Gonse-Boas, Emmanuel Gonse's wife. This specialization attribute to Duval and Gonse, in 1928, the order of their major work, the puericulture School of Paris Medecine Faculty, which is also composing the consecration of their association. Settling the modes of change that have turned an agency originally dedicated to the Parisian property marketing in one of the most fruitful and effective offices invested on the first rehabilitation ground, seemed essential, all like the adaptation of the associates, both at an unusual diversity of designs and at the complexity of regular procedures imposing administrative exactness and working swiftness. In parallel, orders system analysis was allowing to emphasize the strong familial obedience of this agency, which the sanitary and hospital creation is the most spectacular display

This dissertation presents an analysis of the geometry content of Mathematics textbooks. The research objectives were: to explain the specifics of Raymond Duval's semiotic representation theory, with respect to geometry, and to reveal to what extent these specifics are covered in the analyzed textbooks. The central research question we seek to answer is: to what extent does the organization of the geometry content of textbooks consider aspects of Raymond Duval's semiotic representation theory? As a theoretical basis, we use Raymond Duval’s works (2003, 2004). The research involved the analysis of textbooks published between 2002 and 2009, and the data collection and data analysis were supported by Bardin’s content analysis (2010). The research results indicate that the geometry discussed in textbooks has gaps in relation to aspects of Duval’s theory. These gaps relate to possibilities for the development of proposals for education. These are: the interaction between figural and discursive treatments; the linkage between figural register and discourse to minimize the phenomenon of non-congruent semantics (made possible by setting guidelines for submission, problem solving and the demonstration of theorems); mereological or visual modifications responsible for the operative capture of figures, and finally, the resolution of exercises which require organization to enable a systematic variation of visibility factors to facilitate the non-use of definitions or theorems.
A presente dissertação apresenta uma análise do conteúdo de Geometria de livros didáticos de Matemática. Os objetivos da pesquisa foram: explicitar as especificidades da Teoria de Representações Semióticas, segundo Raymond Duval, no tocante à Geometria, e desvelar em que medida essas especificidades são contempladas nos livros didáticos analisados. A questão central da pesquisa que procuramos responder foi: em que medida a abordagem do conteúdo de Geometria nos livros didáticos contempla aspectos da Teoria de Representações Semióticas segundo Raymond Duval? Como fundamentação teórica, utilizamos as contribuições de Raymond Duval (2003, 2004). A pesquisa envolveu a análise de livros didáticos do período de 2002 a 2009, e os procedimentos de coleta e análise dos dados foram subsidiados pela análise de conteúdo de Bardin (2010). Os resultados da pesquisa indicam que a Geometria analisada nos livros didáticos apresenta lacunas em relação a aspectos da teoria de Raymond Duval. Isso acontece no que concerne às possibilidades para o desenvolvimento de propostas para o ensino, considerando: as interações entre tratamentos figurais e discursivos; a articulação entre registro figural e discurso para minimizar o fenômeno da não congruência semântica (possibilitada por orientações para apresentação de definições, resolução de exercícios e demonstração de teoremas); as modificações mereológicas ou visuais responsáveis pela apreensão operatória das figuras; a resolução de exercícios, que exige a organização, em função de uma variação sistemática de fatores de visibilidade para facilitar a não utilização de definições ou teoremas.

Texto completoResumen
The end of slavery in North America presented an opportunity for African Americans in Jacksonville, Florida to reinvent themselves. The reconstruction era brought about new social, political, and economic opportunities for African Americans living in Jacksonville. Despite the failure of Reconstruction and the implementation of Jim Crow, Jacksonville gave birth to a vibrant African American aristocracy. Jacksonville's Black elite comprised of doctors, lawyers, morticians, religious leaders, business people and other professionals. Jacksonville's Black elite thrived in the early half of the twentieth century, many of them used their knowledge and skills to contribute to the social and economic development of Jacksonville's African American community. During this period, Jacksonville's African American aristocracy provided their community with legal protection, healthcare, vocational training, employment opportunities, goods, and other critical services such as life insurance and burial. This study centers on a historical African American cemetery cluster that was established during the early twentieth century by Jacksonville's Black aristocrats. This cemetery cluster consists of four cemeteries which include: Pinehurst, Mount Olive, Sunset Memorial, and Memorial. This cluster is located on the Northside of Jacksonville city, along the intersecting roads of 45th street and Moncrief road, and contains an estimated 70,000 African American burials. I argue that this cemetery is reflective of the social, political, and economic changes undergone by Jacksonville's African American community.

A geometria consiste numa área da Matemática rica em possibilidades de desenvolvimento cognitivo, porém nem sempre valorizada sob esse ponto de vista. A partir dessa constatação, a teoria dos Registros de Representações Semióticas de Raymond Duval (2004, 2005, 2011, 2012a, 2012b, 2013, 2015) evidencia atividades cognitivas referentes ao desenvolvimento do pensamento geométrico, servindo de amparo para possibilidades de melhoria dos processos de ensino e aprendizagem. Uma articulação da geometria com um ambiente dinâmico direciona o presente estudo na busca pela resposta ao seguinte questionamento: De que forma é possível estimular o desenvolvimento de atividades cognitivas segundo Raymond Duval com a utilização do ambiente dinâmico GeoGebra em atividades de geometria? A partir desse questionamento, o objetivo desta pesquisa consiste em apontar contribuições referentes ao uso desse ambiente dinâmico para o trabalho com a Geometria no que diz respeito ao estímulo da visualização de características envolvendo figuras geométricas, indicando quais atividades cognitivas específicas da Teoria dos Registros de Representação Semiótica de Raymond Duval foram presentes. Este estudo foi realizado com 30 alunos do oitavo ano do Ensino Fundamental de uma escola pública do estado do Paraná, em que foram analisadas as produções digitais e escritas dos sujeitos no decorrer da aplicação de uma oficina, cuja temática foi a geometria, com atividades envolvendo polígonos e poliedros por meio do uso do GeoGebra. Como resultado, foi possível inferir que o dinamismo proporcionado pelo ambiente dinâmico GeoGebra foi um facilitador para a identificação de características de determinados objetos matemáticos. A escolha dos conteúdos envolvendo poliedros regulares e não regulares e a Relação de Euler, bem como a retomada de conceitos de polígonos regulares e não regulares determinaram estímulo para a desconstrução dimensional. A presença das apreensões foi identificada e os olhares icônicos mais evidenciados. Por meio do GeoGebra, as explorações das figuras geométricas são eficientes e favorecem o estabelecimento de conjecturas, consequentemente, as apreensões, olhares e a desconstrução dimensional são requisitados.
Geometry consists of an area of mathematics which is rich in possibilities of cognitive development, but not always valued from this point of view. Raymond Duval's Theory of Registers of Semiotic Representations (2004, 2005, 2012, 2012a, 2012b, 2013, 2015) provides a description of cognitive activities related to the development of geometric thinking, serving as a support for possibilities of improving teaching and learning processes. An articulation of the geometry with a dynamic environment directs the present study in the search for the answer to the following question: In what way is it possible to stimulate the development of cognitive activities according to Raymond Duval using the GeoGebra dynamic environment in geometry activities? From this questioning, the objective of this research is to point out contributions referring to the use of this dynamic environment for the work with Geometry with respect to the stimulus of the visualization of characteristics involving geometric figures indicating which specific cognitive activities of the Theory of Semiotic Representation Registers of Raymond Duval were present. This study was carried out with 30 students from the eighth grade of elementary school of a public school in the state of Paraná, in which the subjects' digital and written productions were analyzed during the application of a workshop, whose theme was geometry, with activities involving polygons and polyhedra through the use of GeoGebra. As a result, it was possible to infer that the dynamism provided by the GeoGebra dynamic environment was a facilitator for the identification of characteristics of certain mathematical objects. The choice of contents involving regular and non-regular polyhedra and Euler's Relation, as well as the resumption of concepts of regular and non-regular polygons, provided a stimulus for dimensional deconstruction. The presence of the apprehensions was identified and the iconic views more evident. Through GeoGebra, the explorations of the geometric figures are efficient and favor the establishment of conjectures, consequently, the seizures, views and dimensional deconstruction are required.

Texto completoResumen
Notre thèse s'articule autour de la problématique des rapports entre la presse écrite et le pouvoir politique au cours des événements de 1956 - 1958 à Haïti. Cette période, qui va de la démission du président Magloire en décembre 1956 à la consolidation du pouvoir de François Duvalier en avril 1958, est marquée par de fortes tensions politiques. Elle commence par le combat que se livrent à travers les journaux les partisans du président Magloire et ses opposants à la fin du mandat présidentiel. Le départ de Magloire ouvre une période d'instabilité où se succédent cinq gouvernements en dix mois. Mais parallelement ces deux années sont importantes pour le journalisme haïtien, dans un pays où la presse écrite se caractérise par une existence ancienne et par une grande fragilité. La consolidation du régime de François Duvalier s'accompagne d'une offensive contre la presse écrite qui atteint son point culminant, fin avril 1958, par la fermeture de Haïti-Miroir, le dernier journal de l'opposition. En dépit de l'existence de quelques grands journalistes, l'amateurisme du milieu donne des journaux d'une qualité médiocre qui ne mordent que sur un public très restreint. Les infrastructures matérielles, déjà, sont d'une très grande pauvreté, peu d'imprimeries, peu de centres de diffusion, avec une répartition qui reflète les inégalités qui existent entre les grandes régions du pays. Les problèmes humain ne sont pas les moindres. Toutefois, dans ce contexte peu favorable, les journaux en se lançant dans les luttes politiques des années 1956 - 1958 connaissent une mue importante et s'affirment comme un v'éritable quatrième pouvoir qui tente d'imprimer son cachet à l'actualitéOur thesis deals with this issue related to written Press and political power during the 1956 - 1958 events that occurred in Haiti. This period, originating from President Magloire resignation in 1956 to François Duvalier's mandate conslodation in April 1958 is marked by strong political tensions. That begins with the struggles launched by President Magloire's supporters and opponents at the end of his presidential mandate. A period of instability followed Magloire departure with the succession of five governments in ten months. Besides, those two years are relevant to Haitian journalism , in a country where written Press finds its particularity from oldness and great frality. The consolidation of François Duvalier's regime goes with an offensive against written Press that reaches its climax at the end of April 1958, with the closing of Haiti-Miroir, the last journal of opposition. However, in this difficult situation, journals, by interfering with political struggles during this period, from 1956 to 1958, experienced an important downturn. They ceased to be the place of a single gouvernemental thought to reflect the plurality of coexisting trends of thoughts. Moreover, those journals were also used as a fouth power that tended to cling to actuality and gear the events, in a period stressed by confusion

Texto completoResumen
Research was completed on a 300-person sample of 1985 arrestees in Jacksonville, Florida. The original focus of the study was to explore the possible relationship between crime and chemical use. Data was obtained from forms that were routinely used in the jail booking and interview process. Two booking/intake forms were used: The Arrest and Booking Report and the Medical Screening Information (P-075) form. Only 24 arrestees in the 300-person sample admitted to using chemicals. Hence, the data did not support the hypothesis of this thesis that a correlational relationship exists between crime and chemical use. This researcher observed and interviewed medical personnel closely and reviewed both forms used in the study to determine why chemical use data was under-represented in the sample. Organizational and individual deviance by the medical staff was discovered. The nurses had not asked chemical use questions during a majority of the medical screening interviews.

Texto completoResumen
Au Salon de 1847, Théophile Gautier s’enthousiasme pour l’œuvre d’un tout jeune artiste, Jeunes Grecs faisant battre des coqs par Jean-Léon Gérôme, élève de Delaroche et Gleyre. Scène de genre « à l’antique », l’œuvre se distingue par son charme, sa grâce et sa fraîcheur, loin de la peinture froide et compassée des suiveurs de la tradition davidienne. L’œuvre est aussi le point de départ de la notoriété publique d’un petit groupe de peintres appelés « néo-grecs » – Jean-Louis Hamon, Henri-Pierre Picou, Gustave-Rodolphe Boulanger, Félix Jobbé-Duval, Auguste Toulmouche, Alphonse Isambert et Louis-Frédéric Schützenberger – tous nés autour de 1825, élèves de Paul Delaroche et Charles Gleyre et installés en phalanstère d’artistes de 1846 à 1863, au Chalet, puis à la Boîte à Thé. Dès 1848 et jusqu’aux années 1860, les critiques rendent compte au fil des Salons des évolutions artistiques de ces artistes. La réception critique importance de ces artistes regroupés au sein d’une « école néo-grecque » est symptomatique de l’influence grandissante de la critique sur la constitution des écoles artistiques et sur l’évolution de la carrière des artistes. Leur esthétique va susciter des débats sur le renouvellement de la peinture à l’antique, par l’introduction des notions de pittoresque et de couleur locale, héritées du romantisme, qui vont devenir les caractéristiques du genre historique comme déclinaison légère et sensible de l’ancienne peinture d’histoire. Les premières œuvres néo-grecques vont emporter l’adhésion des critiques inquiets des derniers développements de l’école française, qui voient dans cette nouvelle peinture matière à contrecarrer le réalisme, en apportant au public un art facile d’accès, moralisant les codes de la scène de genre par le recours à l’Antique et à un classicisme formel gracieux. Pourtant, sous une facture classicisante, leur peinture, délibérément antiacadémique, déstabilise rapidement les critiques qui s’interrogent sur les buts artistiques de ces artistes. A ce groupe originel, les critiques associent rapidement d’autres artistes, issus d’horizons très variés, qui adoptent momentanément les codes de l’esthétique néo-grecque, brouillant encore davantage les différences entre peinture d’histoire et genre historique, et entérinant le changement de conception idéologique du modèle antique dans la peinture, qui sera revendiqué par la génération d’artistes des années 1870-1890At the Salon of 1847, Théophile Gautier is enthusiast about the work of art of a young artist, The Cock Fight by Jean-Léon Gérôme, a pupil of Delaroche and Gleyre. This piece of art, an "Antique" genre scene, is a work of elegance, grace and freshness, very different from the cold and formal painting of the Davidian tradition's followers. This artwork is also the starting point of the on coming fame of a small group of painters called "The neo-Greeks" - Jean-Louis Hamon, Henri-Pierre Picou, Gustave-Rodolphe Boulanger, Felix Jobbé-Duval, Auguste Toulmouche, Isambert and Alphonse Louis-Frédéric Schützenberger - all born around 1825. From 1846 to 1863, as students of Paul Delaroche and Charles Gleyre, they all set themselves in a community of artists at the Chalet and the Boite à Thé which one calls a “phalanstère ».From 1848 until the 1860s, all along the Salons, most critics write about the artistic evolutions of these people. The many articles written about the neo-Greeks’works at that time reveales the growing influence of art-critics in the making of artistic schools and the evolution of artists's careers. Their aesthetic will provoke an argument about the renewal of antique theme painting as they introduce the concepts of local color and picturesque, coming from Romanticism, which will become the characteristics of the historical genre as a slight and sensitive declination of the ancient painting of history. The first neo-Greek paintings will gain the support of critics, eager about the latest developments of the French scene. They see in this new stream a way to counteract Realism by giving the public an easy access to art and moralizing the codes of the genre scene by using a formal and graceful classicism with Antique themes. However, though a classical form, their deliberately anti-academic painting soon make the critics wonder about the artistic goals of these artists.In addition to the original group, the critics will soon associate other artists, from very different backgrounds who temporarily adopt the Neo Greek aesthetics's codes, blurring even more the differences between the painting of history and the historical genre. This will also confirm the new ideological conception of Antique model in art, that the painters from the following generation of the 1870’s will claim themselves

Texto completoResumen
Lo scopo del presente elaborato è valutare un eventuale effetto benefico della pallinatura sulla resistenza a fatica di due acciai prodotti per metallurgia delle polveri: il K890, prodotto da Böhler e l’ASP2005, prodotto da Erasteel. Quest’attività si inserisce in un progetto volto a valutare l’idoneità di tali acciai innovativi ad essere impiegati per la realizzazione di componenti motore di moto da corsa, quali alberi a camme, in sostituzione dell’acciaio da nitrurazione GKHW, prodotto da Aubert&Duval con processo ESR (Electro slag remelting). Lo studio è stato svolto a valle di una sperimentazione condotta su provini intagliati degli stessi acciai e ha previsto: prove di fatica a flessione rotante, prove di trazione, prove di durezza, misura di tensioni residue, analisi microstrutturali e frattografiche.
Sono stati testati provini in ASP2005, con durezza pari a 869 HV e in K890 di due diverse durezze, pari a 752 e 821 HV, tutti intagliati e pallinati. Entrambi i materiali hanno mostrato un effetto benefico della pallinatura sul comportamento a fatica; i risultati ottenuti sono stati impiegati al fine di valutare l’applicabilità di relazioni empiriche per la stima del coefficiente di concentrazione a fatica delle tensioni e della sensibilità all’intaglio di acciai ultra-alto resistenziali. È stato dimostrato che le relazioni tradizionali sovrastimano l’effetto dannoso dell’intaglio per questo tipo di acciaio nella condizione pallinata.
È stato, inoltre, condotto uno studio per la modellazione del comportamento a fatica di provini intagliati con un coefficiente di concentrazioni delle tensione Kt=3 e in un secondo momento si è tentato di estendere il modello anche a provini con un Kt compreso fra 1 e 3.
Queste analisi sperimentali sono precedute da un inquadramento generale delle funzioni e dei requisiti di un albero di distribuzione in ambito racing e da una trattazione circa i meccanismi di rottura per fatica in acciai ultra-alto resistenziali.

Lo scopo della presente ricerca è valutare l’idoneità dell’acciaio da utensili innovativo K890, prodotto da Böhler con metallurgia delle polveri, ad essere impiegato per la realizzazione di componenti motore di moto da corsa, quali alberi a camme e a gomiti, in sostituzione dell’acciaio da nitrurazione GKHW, prodotto da Aubert&Duval con processo ESR (Electro Slag Remelting). Lo studio è stato condotto a valle di una precedente sperimentazione condotta su provini non intagliati ed ha previsto l'esecuzione di prove di trazione e prove di fatica a flessione rotante con intaglio oltre a prove di durezza ed analisi microstrutturali e frattografiche.
Sono stati testati due lotti di acciaio K890, aventi durezza di 752 e 821 HV rispettivamente. Durante i test di fatica il lotto in K890 a durezza maggiore ha mostrato un limite di fatica con intaglio superiore al GKHW nitrurato. I risultati ottenuti sui due lotti di K890 sono stati impiegati per valutare l’applicabilità di relazioni empiriche per la stima del coefficiente di concentrazione a fatica delle tensioni ad acciai ultra-alto resistenziali. E’ emerso che le relazioni più tradizionali sovrastimano l’effetto dell’intaglio per questa tipologia di acciaio. A conclusione dello studio, considerando l'esito delle stesse prove condotte sull'acciaio GKHW nitrurato attualmente in uso, si può affermare che l'acciaio K890 è un possibile candidato per la produzione di alberi in ambito racing.
La disamina dei risultati sperimentali è preceduta da tre capitoli incentrati su un inquadramento teorico, derivanti da ricerche bibliografiche: il primo riporta un’introduzione al funzionamento ed alle caratteristiche degli alberi a camme e a gomiti; il secondo è relativo alle proprietà degli acciai da utensili tradizionali ed innovativi; infine il terzo riguarda una trattazione sul danneggiamento da fatica, con particolare riguardo all’effetto dell’intaglio ed alle caratteristiche del fenomeno negli acciai ultra-alto resistenziali.

Texto completoResumen
L’integrazione tra tecniche di biologia molecolare e morfometria geometrica rappresenta un valido strumento per la risoluzione di problematiche tassonomiche e filogenetiche. Questo approccio integrato è stato applicato, in particolare, a due casi di studio. Nel primo, l’analisi di sequenze del gene mitocondriale citocromo c ossidasi subunità II (COII) e l’analisi morfometrica di quattro strutture morfologiche sono state combinate per esaminare il controverso status tassonomico di quattro specie (e varie sottospecie) di coleotteri ipogei del genere Duvalius (Coleoptera, Trechinae), utilizzando principalmente campioni museali raccolti in Italia centrale. Da un lato, l’analisi filogenetica ha evidenziato due linee monofiletiche ben supportate e un certo numero di cladi, con differenze genetiche relativamente basse, suggerendo tempi di divergenza brevi, in linea con la storia geologica dell’area di studio. Dall’altro lato, le analisi di morfometria geometrica hanno riscontrato un alto livello di differenziazione tra i campioni. I due tipi di analisi hanno dato risultati concordanti a livello specifico e non hanno confermato interamente il precedente assetto sistematico, suggerendo possibili riarrangiamenti e la definizione di unità evolutive significative. Il secondo caso ha riguardato due specie di lepidotteri recentemente divise in base alla diversa morfologia dei genitali: Zerynthia polyxena e Z. cassandra. È stato esaminato il livello di divergenza tra 21 popolazioni distribuite dalla Sicilia alla Francia usando tre marcatori genetici (i geni mitocondriali COI e ND1 e il gene nucleare wingless) ed è stata applicata la morfometria geometrica ai genitali. Inoltre, sono stati utilizzati modelli di distribuzione delle specie per valutare le diverse esigenze climatiche di Zerynthia polyxena e Z. cassandra. I dati climatici sono stati poi proiettati nello scenario dell’Ultimo Massimo Glaciale per verificare se e in che misura i cicli glaciali possano aver contribuito al processo di speciazione. Le analisi genetiche e morfometriche hanno identificato due gruppi ben distinti. Tutti i campioni hanno mostrato uno schema di diversificazione concordante per tutti i marcatori usati, senza nessun segno di introgressione, compresi gli individui campionati nell’area di contatto. La distribuzione degli aplotipi e i modelli climatici hanno mostrato che durante l’Ultimo Massimo Glaciale entrambe le specie hanno subito una forte contrazione degli areali e presumibilmente sono rimaste separate in diversi micro-rifugi. La separazione potrebbe essere stata facilitata dalla ridotta capacità di dispersione e dall’alta filopatria, mentre la diversificazione dei genitali ha probabilmente favorito l’assenza di ibridazione.

Burnham, Thorald M. ""Singing Duvalier", singing the nation : masculinity in the discourse of nation formation in Haiti". Thesis, 1999. http://hdl.handle.net/2429/9394.
Texto completoResumen
This thesis argues that no discussion of nationalism is possible without addressing
the subject of masculinity. In the case of Haiti, masculinity is the privileged category of
an oppositional national discourse, or "discent" narrative, and, therefore, orders and ranks
constructions of race, class, language, colour, religion and sexuality. With the election of
Francois Duvalier in September of 1957, the Black urban middle-classes expressed their
interest in changing a national discourse that excluded them both literally and
metaphorically, primarily on the basis of their colour. One year after his election as
President of Haiti, the Musical Institute of Haiti held a song competition in honour of the
new "Father" of the nation. A compilation of the songs was printed and released to the
public. It is through a critical analysis of this booklet, as a site of discursive deployment
of power and the national discourse, that the depth of the masculine narrative can be seen.
Indeed, I argue that the songs of the competition reveal how in "singing Duvalier" they
are in fact singing an oppositional, or "discenting" masculinity. This idea of competing
masculinities is traceable to the origins of Haitian Independence and the establishment of
a national, Black inclusive masculinity lasting until the U.S. occupation in 1915. The
invasion imposed a "marine masculinity" which excluded Black Haitians and destroyed
colour and power sharing etiquettes. Duvalier's election in 1957 was the articulation of
the Black middle-classes' opposition to this new national discourse which had been
perpetuated by the Mulatre elites after the marine's departure in 1934. Indeed, in
"Singing Duvalier", the songs express a new, inclusionary national discourse by
articulating race, class, colour, religion, and sexuality through a rubric of masculinity.

Texto completoResumen
Οι μετασχηματιστές ισχύος αποτελούν τα κρισιμότερα στοιχεία ενός Συστήματος Ηλεκτρικής Ενέργειας από την άποψη κόστους, χρησιμότητας και επικινδυνότητας. Επομένως είναι ιδιαίτερα σημαντικός ο έλεγχος της υγείας των μετασχηματιστών και της λειτουργικής τους ικανότητας. Η παρούσα διπλωματική εργασία ασχολείται με το διαγνωστικό έλεγχο των μεγάλων μετασχηματιστών ελαίου. Για το σκοπό αυτό θεωρείται αναγκαίο να γίνει πρώτα μία αναλυτική αναφορά στους μετασχηματιστές και στις ιδιότητές τους.
Στο κεφάλαιο 1 γίνεται μία σύντομη εισαγωγή σχετική με τα Σ.Η.Ε. ώστε να καταστεί σαφής ο ρόλος των μετασχηματιστών σε αυτά.
Στο κεφάλαιο 2 περιγράφονται λεπτομερώς οι αρχές λειτουργίας και τα κατασκευαστικά στοιχεία των μετασχηματιστών καθώς και τα προβλήματα που προκύπτουν σε αυτούς εξαιτίας της λειτουργίας τους ή από την πάροδο των ετών. Το κεφάλαιο 3 ασχολείται με τη λειτουργική κατάσταση και τη διάρκεια ζωής των μετασχηματιστών και την εξάρτησή τους από την κατάσταση της μόνωσης. Στο κεφάλαιο 4 παρατίθενται όλες οι κλασικές μέθοδοι που χρησιμοποιούνται για την παρακολούθηση και τη διάγνωση σφαλμάτων στους μετασχηματιστές. Επίσης περιγράφονται η κατάταξη των μετασχηματιστών ανάλογα με την ικανότητά τους να παραμείνουν σε λειτουργία και η ένταξη της παρακολούθησής τους στον έλεγχο του συστήματος.
Το κεφάλαιο 5 επικεντρώνεται στη μέθοδο Duval, μία μέθοδο διάγνωσης που συγκαταλέγεται στην κατηγορία των Χημικών Μεθόδων και ειδικότερα της Ανάλυσης των Διαλυμένων Αερίων στο λάδι. Στο κεφάλαιο αυτό γίνεται η περιγραφή της μεθόδου και η παράθεση του προγράμματος που εφαρμόζει τη μέθοδο. Τα παραρτήματα αποσαφηνίζουν κάποιες λεπτομέρειες σχετικές με τη μέθοδο Duval, χρήσιμες για την κατάστρωση του κώδικα.Power transformers are the most critical components of an Electric Power System (E.P.S.) as far as their cost, usefulness and level of risk are concerned. Therefore their maintenance as well as their health and ability to stay in service check are of great importance. This thesis deals with the diagnostics of large oil immersed transformers. Consequently it is considered necessary to begin with a detailed description of power transformers and their attributes. In Chapter 1 a short introduction of E.P.S. is taking place in order to clarify the role of power transformers in them. In Chapter 2 the principles of operation, the manufacturing elements as well as the malfunctions that occur in a transformer because of their use or in the course of time are described in detail . Chapter 3 deals with the operation condition, life-span and the dependency of a transformer on the insulation system condition. In Chapter 4 all the common used techniques for condition monitoring and fault diagnosis of a transformer are displayed. Furthermore the order of the transformers depending on their ability to maintain in operative condition is described as well as the incorporation of their monitoring in the system inspection. Chapter 5 is focused on the Duval method which is a chemical method for fault diagnosis and more specifically a dissolved gas analysis. In this chapter the Duval method is described in detail along with the description of the program that uses this method. The adjuncts clarify some details regarding the Duval method which are necessary for the comprehension of the program.

Texto completoResumen
El Plan de San Diego is the name of an important document in Texas history, but the document and surrounding history is usually discussed with little or no reference to the town of San Diego, Texas, the people who lived there, or the cultural landscape. The Plan de San Diego is an unsuccessful rebellion that is one of the few documented irredentist revolts in U.S. History, it is also a written document calling for return of lands in a multi-ethnic call to arms advocating the recovery of territory by people of Mexican descent in 1915, named for the town San Diego, TX. After the discovery of this Plan, Mexican-Americans were persecuted, violently suppressed, and murdered: 300-5,000 people of Mexican descent died violently following the discovery and publication of the Plan de San Diego in what historians have called the “Bandit Wars”. San Diego, Texas residents and the entire U.S.-Mexican borderlands changed after the discovery of the Plan. My research investigates the political landscape and changes in material and cultural assemblages during and after the Plan, examining how descendant communities retained ties to place and remembered this event in the community of San Diego. Archival research, Historical archaeology and media representations of San Diego explore expose the everyday lives, settlement patterns, and subsistence strategies of the residents of San Diego before and after 1915, showing the material and social effects of the failed rebellion. The socio-political landscape that helped create Mexican-American culture in San Diego is a silenced, violent, and misunderstood chapter of Texas history that shapes the current borderlands and contributes important insights into the study of sites of rebellion and retaliation worldwide.

Trabalho final de mestrado integrado em Medicina àrea científica de Medicina Geral e Familiar, apresentada à Faculdade de Medicina da Universidade de CoimbraA saúde mental tem um peso crescente na sociedade atual, devido à grande morbilidade que acarreta na vida das pessoas. No entanto, a influência que o tipo de família em que cada individuo se insere tem na saúde mental destes não foi ainda aprofundada. O objectivo deste estudo é então caracterizar essa relação. Foram estudadas 180 famílias da região centro de Portugal, utilizando Monografias Familiares elaboradas por alunos do 6º ano médico da Faculdade de Medicina da Universidade de Coimbra em 2011/2012 e arquivadas na Sala Professor Armando Porto, no Centro de Saúde Norton de Matos. Para caracterização das famílias foram estudados os diferentes tipos de família e a fase do Ciclo de Vida Duvall em que se encontravam, sendo também registado o resultado da aplicação de métodos de avaliação familiar como o APGAR familiar de Smilkstein (funcionalidade), a escala de Graffar adaptada (estrato socioeconómico) e ainda a escala de de Segóvia-Dreyer e a Escala de Imperatori (risco familiar). Foram ainda caracterizadas as diferentes patologias do foro mental presentes em cada agregado familiar, tendo estas sido relacionadas através da análise de “cross-tabs” com cada uma das variáveis em estudo. Das 180 agregados familiares, a maioria apresentava um ou mais elementos com doença mental (57,8%), sendo a patologia depressiva e o distúrbio de ansiedade as patologias mais frequentes (41,1% e 14,4%, respetivamente). O tipo de família mais frequente é a família nuclear em relação à estrutura e dinâmica global (54,9%), tradicional em relação à relação conjugal (56,7%) e equilibrada no que diz respeito à relação parental (84%). Nestes tipos de família, considerados estáveis, a prevalência de doença mental foi de 55,7%, 59,2% e 57,9% respetivamente. Quanto ao Ciclo de Vida de Duvall, a fase mais frequente foi a fase VIII (33%) e VI (24%). A primeira estava associada a uma baixa prevalência de doença mental (42,4%), enquanto a última estava associada a uma alta prevalência (68%). Segundo a aplicação do APGAR familiar, a maioria das famílias são “altamente funcionais” (86,9%). Dentro desta classificação, a prevalência de doença mental ascende aos 54,6%. Quanto à escala de Graffar adaptada, a maior parte das famílias estudadas correspondem à “Classe Média” (55%), onde a prevalência de doença mental atinge os 61,4%. Finalmente, segundo as escalas de Segóvia-Dreyer e de Imperatori a maior parte das famílias estudadas são de baixo risco (85,9% e 74,3%, respetivamente). A prevalência de doença mental nestas famílias de baixo risco é de 52,9% e 52,7% respetivamente. Em ambas as escalas a classificação de “alto risco” apresenta uma prevalência de doença mental de 100%. Ficou demonstrado neste estudo que os tipos de família considerados estáveis não são necessariamente os que apresentam menor prevalência de doença mental. No entanto, os tipos de família classicamente instáveis estão de facto associados a uma maior prevalência de doença mental. Quanto ao Ciclo de Vida de Duvall, as fases mais associadas a doença mental são fases em que ocorre readaptação a novos papéis no seio da família (família com filhos pequenos e famílias de meia idade) ou na sociedade (famílias com filhos em idade escolar). O estrato socioeconómico de cada família não mostrou qualquer relação consistente com a prevalência de doença mental. Quanto aos restantes métodos de avaliação familiar (APGAR familiar, escala de Segóvia Dreyer e escala de Imperatori), ficou demonstrado que as classificações de moderado-alto risco/disfunção estão associadas a uma alta prevalência de doença mental. Este estudo mostra a necessidade de mais informação nesta área, uma vez que ficou claro que a família em cada individuo se insere tem um papel importante na prevalência de doença mental.
Mental health is increasingly important in today's society, due to high morbidity which affects in people's lives. However, the influence to mental health that each type of family carries has not yet been established. Therefore, the aim of this study is to characterize this relationship. There were 180 families studied in the central region of Portugal, using Family Reports prepared by students of the 6th Medical Year of the Faculty of Medicine of the University of Coimbra in 2011/2012 and filed in Sala Professor Armando Porto in the Norton de Matos Health Center. For characterization of the families, there were studied all the different types of families and the phase of the Duvall Life Cycle in which they were included. It was also recorded the result of the application of different evaluation methods such as the Smilkstein APGAR family (functionality), the adapted Graffar scale (socioeconomic status) and also Segovia-Dreyer scale and Imperatori scale (familial risk). Finally, the different mental disorders present in each household were characterized and later related to the different variables above, using the “cross-tabs” analysis. Of the 180 households, most of them had one or more members with mental illness (57.8%), depressive disorder and anxiety disorder being the most frequent pathologies (41.1% and 14.4%, respectively). The most common type of family is the nuclear family within overall structure and dynamics (54.9%), the traditional family within marital relationship (56.7%) and the balanced family within the parental relationship (84%). In these types of family, considered to be stable, the prevalence of mental illness was 55.7%, 59.2% and 57.9% respectively. As for Duvall Life Cycle, the most frequent phases were VIII (33%) and VI (24%). The first was associated with a lower prevalence of mental illness (42.4%), while the latter was associated with a high prevalence (68%). According to the application of the familial APGAR, most families are "highly functional" (86.9%). Within this classification, the prevalence of mental illness amounts to 54.6%. According to the adapted Graffar scale, most of the families studied correspond to "Middle Class" (55%), where the prevalence of mental illness reaches 61.4%. Finally, according to the scales of Segovia-Dreyer and Imperatori most families studied are considered to be low risk (85.9% and 74.3%, respectively). The prevalence of mental illness in these families is 52.9% and 52.7% respectively. In both scales the classification of "high risk" has a 100% prevalence of mental illness It was demonstrated in this study that the family types considered to be stable are not necessarily those with lower prevalence of mental illness. However, the types of classically unstable families are indeed associated with a higher prevalence of mental illness. As for the Duvall Life Cycle, the phases associated with mental illness are phases in which adapting to new roles within the family (family with young children and families of middle age) or society (families with school-aged children) occurs. The socioeconomic status of each family showed no consistent relationship with the prevalence of mental illness. The remaining family assessment methods (familial APGAR, Segovia-Dreyer scale and Imperatori scale), demonstrated that the ratings “moderate-high” risk / dysfunction are associated with a high prevalence of mental illness. This study shows the need for more information in this area, since it was clear that each family characteristics play an important role in the prevalence of mental illness

Texto completoResumen
Cette thèse propose l'analyse des processus de l'intégration discursive des « Nouveaux Mondes » – c'est-à-dire des nouveaux lieux de l'expansion européenne des XVe et XVIe siècles – dans les imprimés français d'avant 1560. Le corpus s'y veut exhaustif, mais l'étude porte en priorité sur (1) les mentions brèves (dites sublimées), que celles-ci relèvent de la digression ou qu'elles soient intégrées, et (2) les textes actualisés, c’est-à-dire les traductions, les rééditions avec annexes, les adaptations, etc. Une division bipartite et heuristique est proposée, avec d'une part les actualisations d'écrits procédant par l'exclusion d'un ou d'élément(s) de l'hypotexte (c'est-à-dire du matériel textuel qui préexiste à l'acte de publication), et d'autre part par l'adjonction d'éléments supplémentaires. Cette division permet d'analyser les dits lieux, d'une part en fonction d'un principe de pertinence (lequel est révélé par les phénomènes d'exclusion), et d'autre part en fonction d'une recherche de l'inédit, voire de l'acte contentieux (qu'exprime éloquemment l'acte d'adjonction). La thèse démontre comment les deux principes, celui de la pertinence et celui de la recherche de l'inédit, sont liés à la culture émergente de l'imprimé, ainsi qu'au développement d'une grande variété de genres et de discours: littérature géographique, chroniques annales, pamphlets ou manuels anti-syphilitiques, lettres missionnaires, littérature eschatologique, traités didactiques, etc. Le concept d'acte de publication, qui est corrélatif à celui d'actualisation, permet d'aller au-delà d'une opposition entre l'ouvrage dit « périmé » et l'ouvrage dit « progressiste ». Pour ce faire est reconsidéré l'apport, pour la diffusion des nouveaux lieux, de textes comme le Tractatus de sphaera de Joannes de Sacrobosco (XIIIe siècle) et la lettre apocryphe du Prêtre Jean (XIIe siècle), qui aux XVe et XVIe siècles sont réactualisés suivant une perspective heuristique ou didactique, et participent ainsi à l'émergence d'une économie discursive des « Nouveaux Mondes ».
