The evaluation of the robustness of this controller will be accomplished through simulations, where the control algorithm was subjected to adverse conditions, such as: disturbances, parametric variations and unmodeled dynamic. It was also made a comparison of this control strategy with another one, using classic controllers. In the simulations, it is used a coupled model of the synchronous generator which variables have a high degree of coupling, in other words, if there is a change in the input variables of the generator, it will change all outputs simultaneously. The simulation results show which control strategy performs better and is more robust to disturbances, parametric variations and unmodeled dynamics for the control of Synchronous Generator / A robustez e o desempenho do Controlador Adaptativo por Posicionamento de Polos e Estrutura Variavel s?o avaliados neste trabalho, onde este controlador e aplicado para o controle de um Gerador Sncrono conectado a um barramento infi- nito.

This master thesis presents a research regarding the subject Classic Gravitation in High School. This research was based in two complementary guidelines of research and action. The first guideline was the analysis of 21 didactic books of physics which are the more frequently used in High School, in the city of Natal/RN. The second guideline, worked after being verified the most common deficiencies presents in the didactic books, was the elaboration, followed by a practical application, of a course suggesting how to approach that subject in the classroom. The Par?metros Curriculares Nacionais para o Ensino M?dio (National Curricular Parameters for High School PCNEM) defend that Classic Gravitation is very important in the student s formation and that its study helps the comprehension of many nature s phenomena. Because of this vision of that subject by the PCNEM, the 21 analyzed books were separated in two groups: the first one, containing 10 books, was edited before the spreading of PCNEM, and the second, with 11 books, after that spreading. Whatever the group to which the didactic books belonged, the great majority of them let that subject in a second plan; two of them even suggesting, in the teacher s orientations, that the subject Gravitation can be suppressed in case of insufficient time . These analyses points that the PCNEM had produced no changes in the conception of the authors that wrote books regarding that subject. To analyze the didactic books, we elaborated a script which was used as an analysis tool, in which we put in evidence the relative importance of the historic and philosophic contextualization of the subject, the quotidian experience of the students and the interdisciplinary approach, among other aspects. It became evident that the didactic books give very little emphasis to historic aspects of the knowledge construction, to the relations with the day-by-day questions and to the interdisciplinary character of the subject Gravitation. It calls attention the non concordance among the authors opinions regarding the necessary previous knowledge or prerequisites the students should fulfill in order to begin to study Gravitation. The course we elaborated was given to a group of teachers as well as to students. In those courses we treated theoretical and practical aspects and emphasized historical questions and the ones which are related to people s daily life. The course for teachers was realized as an extra-mural activity of the UFRN and was given by the author of this thesis at the Escola Estadual Francisco Ivo Cavalcanti (a state public school in Natal/RN). There were 23 teachers present, from several public schools and several fields of knowledge. The thesis supervisor and the master degree s colleagues of the author acted as collaborators , reporting the participants opinions and speeches. The course to the students, on the other hand, had the participation of 300 regular students who belonged to 6 different 1st year classes of the High School Escola Marista de Natal (RN), in which the author acts as a physics teacher. The student s course was realized as part of the regular curriculum activities, in which three classes stood under the responsibility of the author and other three classes in charge of another Marista s teacher, who participated as a collaborator . The teacher s course as well as the students one were given in two stages, with five hours each. The first stage was divided in two moments, the first one focused on the survey of the spontaneous conceptions about gravitation, in which we worked basically with experiments of free throwing and pendulum, and the second one focused in theoretical presentations and quarrels about universe s models. In the second stage of the course we improved the study of Kepler s laws and the Newton s Universal Gravitation law, and we used as motivating tools some practices involving the construction of the solar system in scale. As instruments for evaluating both courses we used questionnaires and reported the speeches with participants opinions, beyond usual written evaluations in the course for the students. The teachers who participated in the course showed very good wills in realizing interdisciplinary practices; nevertheless, according their own speeches, they frequently came across the difficulty of how to do . From the experience we had in both courses, we conclude that the approach we propose hear to the teaching of the subject Classic Gravitation , supported on the tripod theory, practice and historical and philosophical aspects, is viable and effective. One hopes that this research may contribute in the formation of a opinion, among the teachers, concerning how to approach the subject of Classic Gravitation, and may offer suggestions in order those who want to apply that approach may develop classroom practices aiming to improve the teaching of that subject, which has a singular importance in the formation of High School students / O tema Gravita??o Cl?ssica faz parte do curr?culo vigente para o Ensino M?dio, sendo ministrado na 1a s?rie desse n?vel de ensino. Esta disserta??o apresenta uma pesquisa a respeito do tema Gravita??o Cl?ssica no Ensino M?dio baseada em dois eixos norteadores e complementares de pesquisa e a??o. O primeiro eixo ap?ia-se na an?lise de 21 livros did?ticos de F?sica, que s?o mais comumente utilizados no Ensino M?dio na cidade de Natal/RN. O segundo eixo, trabalhado ap?s serem verificadas as defici?ncias mais comuns presentes nos livros did?ticos, corresponde ? elabora??o, seguida da aplica??o pr?tica, de um curso sugerindo como abordar o tema em sala de aula. Os Par?metros Curriculares Nacionais para o Ensino M?dio (PCNEM) advogam que esse tema ? muito importante para a forma??o dos alunos e que o seu estudo auxilia na compreens?o de diversos fen?menos da natureza. Considerando essa vis?o do tema pelos PCNEM, os 21 livros analisados foram separados em dois grupos: o primeiro grupo, com 10 livros, foi editado antes da divulga??o dos PCNEM, e o segundo grupo, com 11 livros, ap?s a sua divulga??o. Independentemente de pertencer ao primeiro ou ao segundo grupo, a grande maioria dos livros did?ticos relega o tema para um segundo plano; dois deles chegam ao extremo de sugerir, nas orienta??es aos professores, que o conte?do Gravita??o seja omitido, caso o tempo seja insuficiente . Essa constata??o sinaliza no sentido de que os PCNEM n?o produziram nenhuma mudan?a na concep??o dos autores dos livros a respeito do tema. Para a an?lise dos livros did?ticos, utilizou-se como instrumento um roteiro que elaboramos, por meio do qual se procurou evidenciar a import?ncia relativa da contextualiza??o hist?rica e filos?fica do tema, da experi?ncia cotidiana dos alunos e da interdisciplinaridade, entre outros pontos. Constatou-se que os livros did?ticos pouco enfatizam os aspectos hist?ricos da constru??o do conhecimento, a rela??o com as quest?es do cotidiano e o car?ter interdisciplinar do tema Gravita??o. Chama a aten??o a n?o concord?ncia entre os autores a respeito do conhecimento anterior ou dos pr?-requisitos necess?rios aos alunos para iniciarem o estudo da Gravita??o. O curso que elaboramos foi ministrado tanto para professores como para alunos, sendo abordados aspectos te?ricos e pr?ticos, com ?nfase em quest?es hist?ricas e em quest?es relacionadas com o cotidiano das pessoas. O curso para professores foi realizado como uma atividade de extens?o da UFRN e foi ministrado, pela autora desta disserta??o, na Escola Estadual Francisco Ivo Cavalcanti (Natal/RN). Fizeram-se presentes a esse evento 23 professores de v?rias escolas da rede p?blica e de v?rias ?reas do conhecimento. O orientador e os colegas mestrandos da autora desta disserta??o atuaram como colaboradores, registrando opini?es e relatos dos participantes. O curso para alunos contou com a participa??o de 300 alunos regularmente matriculados em seis diferentes turmas do 1? ano do Ensino M?dio da Escola Marista de Natal/RN, onde a autora desta disserta??o atua como professora de F?sica. Esse curso para alunos foi realizado como parte das atividades curriculares normais, ficando tr?s turmas sob responsabilidade direta da autora desta disserta??o e tr?s outras a cargo de outro professor da escola, que atuou como colaborador. Tanto o curso para professores como o curso para alunos constou de duas etapas, cada uma de 5 horas. A primeira etapa foi desdobrada em dois momentos, sendo o primeiro centrado no levantamento das concep??es espont?neas sobre Gravita??o, trabalhando-se basicamente com os experimentos de lan?amento livre e p?ndulo; o segundo momento centrou-se em apresenta??es te?ricas e discuss?es sobre os modelos de universo. A segunda etapa do curso foi um aprofundamento sobre as Leis de Kepler e a Lei da Gravita??o Universal de Newton, sendo utilizadas, como instrumentos motivadores, pr?ticas envolvendo constru??es do sistema solar em escala. Como instrumentos de avalia??o de ambos os cursos, foram utilizados question?rios e relatos de opini?es, al?m de avalia??es usuais, na vers?o do curso para alunos. Os professores participantes demonstraram disponibilidade para realizar pr?ticas interdisciplinares; todavia, segundo seus pr?prios relatos, eles freq?entemente esbarravam na dificuldade do como fazer . Da experi?ncia vivida nos dois cursos, verificou-se que a abordagem aqui proposta para o tema Gravita??o Cl?ssica, apoiada no trip? teoria, pr?tica e aspectos hist?ricos e filos?ficos, ? vi?vel e efetiva. Espera-se que essa pesquisa possa contribuir na forma??o de uma opini?o, entre os professores, a respeito de como abordar o tema Gravita??o Cl?ssica, e possa fornecer subs?dios para que os interessados desenvolvam pr?ticas em sala de aula visando aprimorar o ensino desse tema, que ? de import?ncia ?mpar na forma??o dos alunos do Ensino M?dio

La présente étude revient sur le concept de théâtralité souvent employé à propos du Satyricon pour tenter d’enpréciser les manifestations et les modalités. Car derrière l’apparente simplicité du terme et la banalisation de sonemploi à propos de cette oeuvre, se cache une pluralité de procédés. La théâtralité du Satyricon revêt trois formes.Elle se définit spontanément comme la réutilisation de codes propres aux genres dramatiques comiques auxquelsPétrone emprunte situations, thématiques et procédés linguistiques. Cette théâtralité première est complexifiéepar son ancrage dans un univers narratif orienté, dont les préoccupations recoupent celles du genre satirique. Lerecours à des éléments théâtraux dessine les contours d’une société excessive et inauthentique, et se voit doncfiltrée par le topos du monde décadent : cette théâtralité seconde devient le moyen d’exprimer l’outrance desindividus et de leurs comportements. Et c’est précisément parce que dans le monde du Satyricon les valeurstraditionnelles sont caduques que la littérature classique est obsolète. S’ouvre alors la voie à une théâtralitétroisième, intrinsèquement liée à la parodie. Elle est principalement portée par la voix du narrateur, chez qui lapratique excessive de la déclamation a entraîné une projection systématique dans un au-Delà fictionnel. Lafracture existant désormais entre la réalité et sa perception a une double conséquence : d’une part toutes lessituations du quotidien s’assimilent à des représentations de scènes littéraires de référence ; d’autre part elledéconstruit la littérature traditionnelle en en exhibant les clichés. Cette théâtralité permet à Pétrone de renouvelerla littérature et de jeter les bases du genre romanesque. / The present study reexamines on the concept of theatricality often used about the Satyrica to try to specifyappearances and methods. For behind the visible simplicity of the term and the everyday acceptance of its use inrelation to this work, there hides a plurality of processes. The theatricality of the Satyrica takes on three forms. Itdefines itself spontaneously as the re-Use of codes particular to the funny dramatic genres from which Petroniusborrows situations, themes and linguistic processes. This first theatricality is complicated by its anchoring in adirected narrative universe, whose concerns it shares with those of the satiric genre. The falling back on theatricalelements outlines an excessive and inauthentic society, and thus sees itself filtered by the decadent world topos.And it is exactly because in the world of the Satyrica the traditional values are null and void that classicalliterature is obsolete. The way is then opens to the third theatricality, intrinsically connected to parody. It ismainly carried by the voice of the narrator, to whom the excessive practice of declamation entailed a systematicprojection to a fictional otherworld. The fracture existing from now on between reality and its perception has adouble consequence: on the one hand all the situations of everyday life can be reduced to representations ofliterary reference scenes ; on the other hand it deconstructs the traditional literature through clichés. Thistheatricality allows Petronius to renew literature and to lay the foundations for the novelistic genre.

This essay presents a theoretical foundation for the analysis concepción on the formation of the equilibrium between aggregate supply and aggregate demand in the classical model. To arrive at the considerations presented here, the history of classical economic thought was taken into account, drawing as a starting point the rupture of mercantilism. From this historic mark it was possible to describe the main names that were responsible for changing the economic conception during the years that followed. It was also tried to report some of the your most import contributions to the formation of orthodox ideas of the classical school, which are in force and are reformulated up to the present moment. With the construction of the theoretical and graphic model, then presents the importance and coherence coexistente in the exposed model, evidencing its impacts on the evolution of economic thinking. / Este ensaio apresenta a fundamentação teórica para a concepção da análise sobre a formação do equilíbrio entre oferta agregada e demanda agregada no modelo clássico. Para chegar a considerações aqui apresentadas levou-se em estima a história do pensamento clássico econômico, traçando como ponto de partida a ruptura do mercantilismo. A partir deste marco foi possível descrever os principais nomes que foram responsáveis pela mudança da concepção econômica durante os anos que se seguiram. Procurou-se, ainda, relatar algumas de suas principais contribuições para a formação das ideias ortodoxas da escola clássica, que vigoram e são reformuladas até o presente momento. Com a construção do modelo teórico e gráfico mostrou-se a importância e coerência coexistente no modelo exposto, evidenciando seus impactos na evolução do pensamento econômico.

In his novel Chegou o Governador, published in 1987, the author esthetically presents a realm that drives the reader to a specific historical period of Goiás which are the years between 1804 and 1809. These years correspond to the events of the arrival and departure of D. Francisco de Assis Mascarenhas, a distinguished political character of the Portuguese colonial company, who masterfully led the captaincy of Goiás during these years, according to the local historiography which were considered by Bernardo Élis in his novel. It can be observed the novel establishes an explicit dialogue to the historical studies, that is why, in this research we have proposed, it was necessary to analyze the historiographical records that have mapped the central regions of Brazil during the nineteenth century, moreover, to find the notes that were responsible to notice the events of Goiás during the beginning of the nineteenth century. For that reason, the first step I have taken was to take notes about what the History could tell. After that, it was necessary and approach on the amount of Bernardo Élis‟s works, all of them published in a period of more than four decades, in order to perceive the novelist‟s line of thought, related to the social and historical representation. This step let us explore another frequent discussion, the border limit between Literature and History through the reflection done by scholars and important representatives of both fields of knowledge. After that, the research focuses the discussion of the novel as the structure of artistic creation which gets closer to the problematized social events. It is known that this plural narrative has the History‟s features in its foundation and it is able to make use of this feature as the helm to the fictional work. When we bring out these questions, we are in the main purpose of this research: understanding in which theoretical base the Bernardo Élis‟ novel is established, whether in the principles of classic historical novel, theorized by Georg Lukács (1966), or in the operating modes of the new historical novel, discussed by Fernando Ainsa (1991), or if the novel moves among the both models, and if it does, how it happens. Finally, Chegou o governador is analytically seen in the bases of the theoretical principle mentioned. It is possible to verify how Bernardo Élis made use of the history of his people to illustrate it and problematize it through fiction getting a broader and more complex sense of the events that could demonstrate the local historical movement. By doing this, Élis complies with what we believe is the artist's role: show what is not said, sharpening the critical awareness of the reader about the controversial and contradictory progress of the History. / Neste trabalho proponho averiguar como o poeta, contista e romancista Bernardo Élis se apropria da história goiana para reconstruir, pelas vias da ficção, o cenário econômico, político e social próprio desse lugar, no início do século XIX. Em seu romance Chegou o governador, publicado em 1987, o autor apresenta, esteticamente, uma atmosfera que transporta o leitor para um determinado momento histórico de Goiás, a saber, os anos entre 1804 e 1809, correspondentes aos episódios de chegada e saída de D. Francisco de Assis Mascarenhas, ilustre figura política da empresa colonial portuguesa que governou magistralmente a Capitania de Goiás nos anos citados, segundo nos apresenta a historiografia local de que se vale nosso autor da ficção. Percebe-se assim, que a obra romanceada estabelece diálogo explícito com as ciências históricas, por isso mesmo, na pesquisa que propusemos, foi necessário analisar os registros historiográficos que mapearam as regiões centrais do Brasil durante o século XIX, mais especificamente, encontrar os apontamentos que deram conta dos fatos ocorridos em Goiás durante os primeiros anos do mencionado século. Por isso mesmo, o primeiro passo aqui foi anotar o que a história pôde contar. Em seguida, fez-se importante a abordagem sobre o conjunto de obras do autor da ficção, publicado em um período superior a quatro décadas, para perceber uma linha de força inerente ao romancista, a saber, a da representação social, por decorrência, histórica. Esse passo nos permitiu explorar outra discussão ainda hoje muito em voga, a relação entre literatura e história e o limite da fronteira entre as duas áreas, fazendo uso da reflexão de teóricos e importantes representantes dos dois campos. Posteriormente, a pesquisa enfoca a discussão do gênero romance como estrutura de criação artística que melhor se aproxima dos extratos sociais problematizados. É sabido que essa narrativa plural tem em sua fundação as marcas próprias da história, e por esse aspecto, apta a captá-las como mote para a elaboração ficcional. Ao discutir essas questões, chega-se ao fundamento maior dessa pesquisa, compreender sob qual base teórica o romance de Bernardo Élis está balizado: se nos princípios do romance histórico clássico, teorizados por Georg Lukács (1966); ou, se nos modos operacionais do novo romance histórico, discutidos por Fernando Ainsa (1991), ou, ainda, se a obra cotejada transita entre os modelos propostos e, se transita, de que maneira o faz. Por fim, Chegou o governador é visto, analiticamente, com base nas premissas teóricas apresentadas acima. É possível verificar como Bernardo Élis se valeu da história de seu povo para ilustrá-la e problematizá-la através da ficção, obtendo assim um sentido mais amplo e complexo dos fatos, que desse a ver o próprio movimento histórico local. Ao fazê-lo, Élis cumpre com aquilo que acreditamos ser o papel do artista: evidenciar o que não está dito, aguçando a consciência crítica do leitor sobre o andamento controverso e contraditório da história.

No. of bitstreams: 1 Luiz Antonio Brandt.pdf: 1067816 bytes, checksum: 69a6a677b5382a0454f7bbd9551ddd1f (MD5) Previous issue date: 2011-12-08 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / In this thesis, we aim to conduct a study and reconstruction of the criticism that Galileo undertakes to physics and cosmology of Aristotle, and works as an anchor Sidereus Nuncius and First Day of Dialogue Concerning the Two Chief World Systems. The arguments developed by Italian physicist these works, consolidating the Copernican theory and revolutionize the way we study nature. For centuries, the Western conception of the universe was supported by the assumptions of cosmology of Aristotle. Aristotelian cosmology had as fundamental points the idea of the incorruptibility of the heavens, the earth and the immobility of a hierarchy of elements. For the peripatetic, the cosmos was finite and heterogeneous, and was divided into two distinct regions: the sublunary (terrestrial) and above the Moon (heavenly). The telescopic observations made by Galileo in 1609, showing craters and mountains on the moon and Jupiter's satellites, were in evidence against the heaven-earth dichotomy proposed by Aristotle. For it revealed "imperfections" in the heavenly bodies, and showed that not all the stars had their revolutions as the center of the Earth, the idea of asking the same centrality in the cosmos. Moreover, the break with Aristotelian cosmology destabilizing the very physics of Aristotle, whose explanation of the movements of bodies depended on the cosmological structure, since there were three types of moves, straight toward the center, straight away from the center and circular around the center, which required a motionless earth occupying the center of the cosmos. The idea of centrality and immobility of the Earth is therefore fundamental point of Aristotelian physics and cosmology. Most of the work of Galileo Galilei seems to think about a central objective: the defense of the Copernican theory. Since his public adhesion to the Copernicanism in 1610, in Sidereus Nuncius, until Dialogue published in 1632, the Pisan Phisycist sought to break with the assumptions of the Aristotle s natural philosophy which supported the geocentric conception. As a result, it is in First Day of Dialogue that, certainly, we could find a more systematic and focused effort against the Aristotelic conception of world and its main characteristic: the dissociation of the cosmos into two distinct regions, the celestial and sublunary. / Nesta dissertação, temos como objetivo realizar um estudo e reconstrução das críticas que Galileu empreende à física e à cosmologia de Aristóteles, tendo como âncora as obras Sidereus Nuncius e Primeira Jornada do Diálogo sobre os dois máximos sistemas do mundo. Os argumentos desenvolvidos pelo físico pisano nestas obras, consolidam a teoria copernicana e revolucionam a maneira de se estudar a natureza. Durante séculos, a concepção ocidental de universo esteve apoiada nos pressupostos da cosmologia de Aristóteles. A cosmologia aristotélica tinha como pontos fundamentais a ideia de incorruptibilidade do céu, de imobilidade da Terra e de uma hierarquia dos elementos. Para o peripatético, o cosmos era finito e heterogêneo, e se encontrava dividido em duas regiões distintas: a sublunar (terrestre) e a supralunar (celeste). As observações telescópicas realizadas por Galileu em 1609, ao mostrar crateras e montanhas na Lua, e satélites em Júpiter, constituíram-se em evidências contrárias à dicotomia céu-Terra proposta por Aristóteles. Pois revelavam imperfeições nos corpos celestes, e mostravam que nem todos os astros tinham como centro de suas revoluções a Terra, questionando a ideia de centralidade da mesma no cosmos. Além disso, a ruptura com a cosmologia aristotélica desestabilizava a própria física de Aristóteles, cuja explicação dos movimentos dos corpos dependia da estrutura cosmológica, uma vez que existiam três tipos de movimentos: retilíneo em direção ao centro, retilíneo se afastando do centro e circular em torno do centro, o que requeria uma Terra imóvel ocupando o centro do cosmos. A ideia de centralidade e imobilidade da Terra é, portanto, ponto fundamental da física e da cosmologia aristotélicas. Grande parte da obra de Galileu parece girar em torno de um objetivo central: a defesa da teoria copernicana. Desde a sua adesão pública ao copernicanismo em 1610, no Sidereus Nuncius, até o Diálogo publicado em 1632, o físico pisano buscou romper com os pressupostos da filosofia natural de Aristóteles que sustentavam a concepção geocêntrica. Com efeito, é na Primeira Jornada do Diálogo que poderemos encontrar um esforço mais sistemático e concentrado contra a concepção aristotélica de mundo e sua principal característica: a dualidade do cosmos.

The purpose of this paper is twofold. Firstly, it makes a normative idea analysis concerning organ donation, by comparing the perspectives of utilitarianism and classical liberalism. Secondly, it applies these perspectives on the Swedish legislation, in order to understand it in a political philosophical view. As a theoretical framework, the paper uses the two perspectives´ overarching ethical standpoints, but also try to discern their views on four - for the topic -appropriate concepts, these being the concepts of liberty, consent and self-ownership. These are then bundled together into two so-called ”ideal types”, to use for making normative statements about what the most morally right legislation would be concerning organ donation. In utilitarianism, an agent-neutral overall happiness is at the forefront, which leads it to prioritize an increase in donations over the autonomy of the individual. This makes the case for a conscription of organs or the softer notion of an opt-out system. Classical liberalism focus more on the right to self-ownership and negative liberty, and therefore argue for an opt-in system, which requires the explicit consent of the individual. Lastly, the paper makes the claim that the Swedish legislation falls in a category inbetween the normative judgements of the two perspectives, as it prescribes an opt-out system, but reserves the right of the family to refuse a donation, in case the deceased had not made a choice ante mortem.

Cette thèse s’intéresse à l’impact du développement des Grandes et Moyennes Surfaces (GMS) sur les producteurs de produits agricoles Jordaniens. Ce travail essaye d’approcher les évolutions nécessaires aux exploitations agricoles traditionnelles, qui écoulent leur production dans les marchés de gros, pour se préparer aux exigences agronomiques, techniques et managériales propres aux circuits de distribution modernes. Cette thèse montre également que la vente dans les GMS n’est pas pour l’instant très rentable pour les agriculteurs Jordaniens. Malgré ce constat, ces derniers adoptent une stratégie d’anticipation en se positionnant dès aujourd’hui dans cette chaîne moderne. / This these focuses on the impact of the development of food retailing on Jordanian agricultural producers. This work is particularly interesting because it allows us to approach the evolutions necessary for traditional farms, which dispose of their production in the wholesale markets, in order to prepare themselves for the agronomic, technical and managerial requirements of modern channels. This thesis also shows that the sale in the supermarkets is not for the moment very profitable for the Jordanian farmers. Despite this, they are adopting a strategy of anticipation by positioning themselves today in this modern chain.

Ce mémoire présente l’analyse technologique d’un assemblage lithique du Dorsétien récent provenant des Îles Nuvuk au Nunavik. L’approche technologique et la chaine opératoire ont été employées pour définir le système technique des occupants de la maison 3 du site KcFs-2, daté entre 940±20 ans et 970±15 ans AA. Les analyses technologiques ont permis d’aborder une multitude de sphères comportementales en relation avec la technologie lithique dorsétienne de KcFs-2. Celles-ci concernent l’acquisition des matières, la gestion des supports, les intentions de production, les techniques de taille et enfin, les conceptions volumétriques des occupants du site. Dans le but de questionner le cadre chronoculturel en vigueur et de pallier aux manquements de l’approche typologique traditionnellement employée dans l’Arctique de l’est, ces données ont été comparées à celles des sites GhGk-63 (Kuujjuarapik) et Tayara (KbFk-7) ayant servi à définir la période du Dorsétien classique au Nunavik (Desrosiers 2009). L’analyse comparative des systèmes techniques du Dorsétien classique et du Dorsétien récent a permis de mettre en lumière la continuité des traditions techniques dorsétiennes sur une période d’environ mille ans. / This thesis presents the technological analysis of a Late Dorset lithic assemblage from the Nuvuk Islands in Nunavik. The technological approach and the chaine opératoire have been used to define the “technological system” of the occupants of House 3 at KcFs-2, dated between 940±20 and 970±15 BP. The technological analysis has provided information about many spheres of technological behavior related to the acquisition of raw material, to the management of blanks and preforms, to production objectives, to knapping techniques and finally to the “volumetric conceptions’’ of the site’s occupants. In order to question the actual chronocultural framework and to overcome problems associated with the typological approach traditionally used in the Eastern Arctic, this data has been compared to the data from the GhGk-63 (Kuujjuarapik) and Tayara (KbFk-7) sites, which have been use to define the Classic Dorset in Nunavik (Desrosiers 2009). The comparative analysis of Classic Dorset and Late Dorset “technological systems” has shed light on the continuities that characterise Dorset technological traditions over approximatively a millennium.

Selon le philosophe Gilles Deleuze, l’arrivée du néo-réalisme italien constitue le point de passage entre une forme classique du cinéma (L’image-mouvement) et une forme moderne (L’image-temps) entre le cinéma moderne. Une telle distinction est largement approuvée par les théoriciens, les critiques les historiens du cinéma. Loin de correspondre à unerupture historique, elle renvoie à deux types de cinéma qui possèdent leurs propres caractéristiques. Cette étude envisage dans un premier temps d’aborder, à partir de la typologie deleuzienne, les spécificités de chacun de ces régimes du point de vue de la création. Les films de Takeshi Kitano, cinéaste japonais, et Hong Sangsoo, cinéaste coréen, sont analysés selon cette perspective. Les premiers présentent effectivement une structure basée sur un régime classique, tandis que les seconds se fondent sur les caractéristiques du cinéma dit moderne. Leur analyse permet aussi de suivre le processuscréatif de ces deux réalisateurs reconnus internationalement. Cette étude tente, dans un deuxième temps, de montrer qu’ils s’inscrivent dans une perspective universelle sur le plan de la création. / According to the studies of French philosopher Gilles Deleuze, the arrival of Italian neorealism is the crossing point between a classic form of film (The movement-image) and a modern one (The time-image). Such a distinction is widely endorsed by theorists, critics and historians of films. Far from corresponding to a historical rupture, it refers to two types of films that have their own characteristics. This study intends initially to approach, from Deleuze's typology, the specifics of each of these regimes in terms of creation. The films of Takeshi Kitano, Japanese filmmaker, and Hong Sangsoo, Korean director, are analyzed under this prospect. The former represent a structure based on a classical scheme, while the latter is based on the characteristics of modern film. The analyst also allows following the creative process of these two internationally renowned filmmakers. This study attempts secondly to illustrate that they have a universal perspective in terms of creation.
