Esta tesis aborda el estudio de la temporalidad moderna a través del cine de vanguardia europeo de los años 20. Este cine recoge todas las temporalidades que habían sido desechadas por la idea lineal y progresiva del tiempo heredada de la Ilustración y desafía de manera sistemática su construcción discursiva y la comprensión histórica que generaba para el periodo de entreguerras. El cine de vanguardia es un medio privilegiado para estudiar la experiencia temporal moderna porque es un complejo compendio de tiempos y discontinuidades. Y a su vez, la temporalidad es clave para definir y estudiar la vanguardia cinematográfica. En ella se unen el interés por la exploración del movimiento, los experimentos con la imagen, la desafección narrativa y la afección por lo real. Propone también la subversión del campo fílmico (y, por veces, social). Los cineastas de vanguardia no construían un discurso temporal alternativo pero sí se dotaban de un cuerpo coherente de revuelta basado en la exploración de esas temporalidades diversas. Trataron también de establecer la imagen como método, de deconstruir la racionalización instrumental del dominio visual y propusieron que de la variedad de discursos temporales en convivencia emanaba una nueva forma de historia y de imagen. / This thesis analyzes the modern temporality through the 20’s European avant-garde cinema. This cinema picks up all the temporalities that have been rejected by the Illustrated idea of time as linear and progressive. As a consequence, this cinema systematically defies the Illustrated discursive construction and the historical comprehension that it elaborated during the Interwars period. Avant-garde cinema was a privileged means to study the modern time experience because it is a complex compendium of times and discontinuities. At the same time, the temporality is a key element to define and study the cinematographic avant-garde. This cinema is characterized by the exploration of movement, the experiments with the image, its lack of interest in narrativity and its interest on the real. It also proposes a subversion of the filmic field (and sometimes, also the social field). Avant-garde filmmakers did not construct an alternative temporal discourse but they organized a coherent uprising corpus based on the exploration of those diverse temporalities. They established the image as a method, the deconstruction of the instrumental rationalization of the visual dominion and they proposed that a new type of history and image emanates from the coexistence of the variety of temporal discourses.

Cette thèse a pour objectif d’expliquer pourquoi l’insertion de comptes-rendus de perception ou CRP dans un fragment narratif, lorsqu’elle entraîne une rupture dans la progression thématique de ce fragment, ne compromet pas sa compréhension.Les études narratologiques (Hamon, Adam et Petitjean) définissent les textes descriptifs comme des séquences qui se caractérisent par des marqueurs d’introduction et de clôture corrélés. Les études sur l’accès cognitif à l’information (Vogeleer) montrent, par ailleurs, que les CRP décrivent une situation accessible dans la situation spatio-temporelle d’un sujet. Ce sont des énoncés thétiques qui se caractérisent par leur absence de thème (Furukawa). A l’écrit, le contexte gauche d’un CRP peut compenser son absence de thème en décrivant une situation qui permet d’inférer le lieu cible de perception (Emma s’approcha de la fenêtre) d’un sujet introduit en amont. Les énoncés de ce type sont ainsi apparentés au DIL.La classification d’un corpus de CRP intégrant les noms fenêtre(s) et porte(s), nous a conduit à distinguer six types de CRP parmi lesquels les séquences de compte rendu de perception indirect libre ou CRPIL sont les plus fréquentes. Dans ces séquences, lorsque le premier CRP de l’extrait n’a aucun lien avec son contexte gauche, il décrit une situation perçue accessible dans la situation spatio-temporelle du sujet qui la perçoit, qui est donc inédite jusqu’à son introduction dans le monde fictif. La coïncidence spatio-temporelle entre le sujet et cette situation peut être dénotée dans certains extraits par un SP spatial ou temporel antéposé dans le premier CRP de la séquence et potentiellement cadratif (Charolles). Ce SP signale le point de vue du sujet introduit en amont, dénote le lieu cible ou la localisation temporelle de la situation décrite dans le CRP et permet d’interpréter tous les CRP de la séquence. Dans les extraits ne mentionnant pas de SP, le lieu cible et le temps de la situation perçue sont inférés dès l’introduction du premier CRP, cette inférence validant tous les CRP de la séquence. La rupture topicale suscitée par l’introduction des CRP signale, dans tous les cas, l’émergence du point de vue d’un personnage introduit en amont. / The aim of this thesis is to explain why the inclusion of perceptual reports (PRs) in a literary narrative does not interfere with the comprehension of such narratives, despite when breaking their thematic progression.Narratological studies (Hamon, Adam and Petitjean) define descriptive texts as sequences characterised by correlated introductory and closing markers. Furthermore, research on evidentiality (Vogeleer) shows that PR describe a situation that is accessible in the space/time situation of a subject. PRs are thetics statements characterised by a lack of topic (Furukawa). In the written form, the left context of the PR may make up for the lack of topic by describing a situation that may be used to infer the place targeted by the perception (Emma s’approcha de la fenêtre) of a subject introduced earlier. Statements of this type are thus similar to represented speech and thought or RST.The classification of a corpus of PRs incorporating the nouns fenêtre(s) and porte(s), leads us to distinguish six PRs types among which represented perceptual reports (RPRs), are most frequent. In these sequences, when the first PR of the excerpt has no link to its left context, it describes a perceived situation accessible in the spatial/temporal situation of the subject that perceives it, which is therefore unknown until introduced into the fictitious world. The spatial and temporal coincidence of the subject and this situation may be noted in certain excerpts by a spatial or temporal prepositional phrase (PP) that is placed earlier in the first PR of the sequence and that is potentially framing (Charolles). This PP signals the point of view of the subject introduced earlier, denotes the target location or temporal location of the situation described in the PR and makes it possible to interpret all the PRs in the sequence. In the excerpts that do not mention a PP, the target location and time of the perceived situation are inferred once the first PR is introduced, with this inference validating all perceptual reports in the sequence. The topical break caused by the introduction of PRs signals, in all cases, the emergence of the point of view of a character introduced earlier.

The purpose of this Master’s thesis is to examine queer aspects of the animated television show Steven Universe (2013-present), created by Rebecca Sugar and produced by Cartoon Network. Situating Steven Universe in the context of Cartoon Network and children’s animation in general, and drawing on queer theory, as well as feminist cultural studies and kinship studies, the thesis aims to contribute to understanding of non-normative family representation in children’s entertainment. Through a close reading of the material, the thesis explores how Steven Universe queers the notion of family. It focuses on the show’s depiction of kinship, temporality and reproduction, and examines how each of these aspects subverts reproduces different modes of normativity. In Steven Universe, the family of the main character, Steven, is depicted as socially unintelligible, and as a mixture of biological and chosen kinship, highlighting the importance of both. It places great emphasis on being accepted by one’s family and community, and I discuss how this message can be both empowering and undermining. Steven’s family mostly inhabits queer time and does not give in to chrononormative structures. However, I also explore and critically evaluate parts of the series in which queer temporality is provisionally replaced by chrononormativity and striving for maturity. Finally, Steven Universe queers reproduction, by defamiliarizing the notion of (hetero)sexual reproduction and providing other alternatives for reproduction and motherhood. In general, the depiction of family on Steven Universe is characterized by transgressing multiple dichotomies and by having a complex relationship to different modes of normativity, by both resisting them and engaging in them.

A partir de referências conceituais da Análise do Discurso, propõe-se uma compreensão do discurso jornalístico da atualidade como um efeito de sentido produzido a partir da associação a determinadas representações da figura do tempo. Discute-se o regime de historicidade que contemporaneamente articula o discurso jornalístico do jornal diário impresso e verifica-se em que medida a representação da experiência do tempo no relato dos jornais vale-se proeminentemente de um regime de “presentismo” no qual se tende a sugerir certo tipo de equivalência entre tempo presente e atualidade. Como estratégia metodológica para se pensar o sistema temporal do jornal, realizou-se análise comparativa do tratamento que quatro jornais diários de “referência” (Folha de S.Paulo, O Globo, Estado de Minas, Agora) dão aos chamados acontecimentos do dia e os modos como sistematizam o mundo, elaborando a dispersão dos fatos em estruturas sintagmáticas e paradigmáticas destinadas a essa finalidade. / Salvador

La Turquie forme un cadre exceptionnel pour l’étude de la question d’asile dans le sens où les politiques mises en œuvre concernant ce sujet ne correspondent pas à la complexité de la réalité sur ce territoire. C’est l’un des rares pays au monde qui applique – encore aujourd’hui - la Convention de Genève avec deux réserves, géographique et temporelle. Cette version de la Convention indique que seuls les réfugiés et demandeurs d’asile « européens » fuyant des événements antérieurs au 1er Janvier 1951 peuvent demander le statut de réfugiés auprès de l’Etat turc. En conséquence, aujourd’hui, l’Etat turc ne délivre pas le statut de réfugié aux demandeurs d’asile non-européens mais fournit seulement un statut temporaire. Les personnes, qui obtiennent le statut de réfugié d’après la définition internationale, sont autorisées à rester dans le pays uniquement jusqu’à ce que leur réinstallation dans un pays tiers soit organisée par le Haut Commissariat des Nations Unies pour les Refugiés (HCR).Basée sur des recherches effectuées sur les demandeurs d’asile iraniens à Van, une ville frontière de l’est de la Turquie, cette étude analyse le fonctionnement du processus de légalisation des personnes dans un contexte transitoire en se concentrant sur la relation entre les différents acteurs : les Etats, le HCR, les acteurs informels et les demandeurs d’asile. Elle explore la relation simultanée entre la légalité, la temporalité et le statut de réfugié à trois différents niveaux : local, national et transnational. Cette étude examine comment le statut transitoire du demandeur d’asile structure la relation de l’individu avec la légalité et comment il oriente la personne dans ses stratégies politiques et l’organisation de sa (sur)vie pendant cette période. Ainsi sont étudiées les conséquences des notions de légalité et temporalité sur l’expérience des demandeurs d’asile en Turquie. / Despite the increasing number of people entering Turkey as asylum seekers, the Turkish state has maintained the “rule of geographical reservation” that does not allow non- European asylum seekers to remain in Turkey as refugees. Accordingly, the on-going asylum system does not offer refugee status for non-European asylum seekers, but merely provides a temporary status. So-called “Temporary Guest”, these individuals are only allowed to stay within the country until their resettlement in a third country has been arranged by the United Nations for High Commissariat of refugee. This research concerns itself with the study of the experiences of Iranian asylum seekers and refugees residing in Van, a border satellite city in Eastern Turkey, currently in the process of transition. It analyzes the experience of being a refugee and being “in transit” in a country geographically proximate to the country of one’s origin. It examine individuals’ legalization struggle within transitory, local, national and transnational context by focusing on interacted/intersected relationship between states, international refugee regime, informal actors and asylum applicants. In so doing, it suggest exploring the ways in which legality and temporality come to be so intricately related as to form one’s refugee experience in Turkey.

Este trabalho tem por objetivo relacionar o ensino de História, as noções de tempo e as relações de temporalidade. O estudo aconteceu a partir da experiência de elaboração do curso de formação continuada O Ensino de História, as noções de tempo e as relações de temporalidade e sua aplicação junto aos professores da rede municipal de ensino do município de Arroio do Meio/RS. Pretendeu-se discutir fundamentos teóricos e metodológicos de maneira a correlacionar os temas e qualificar a ação docente no Ensino Básico. A pesquisa foi desenvolvida a partir da observação e análise de materiais produzidos pelos professores participantes e utilizando mecanismos vindos dos estudos etnográficos, como o caderno de campo. Nessa proposta utilizou-se o conceito de Tempo Histórico a partir dos estudos do historiador Reinhart Koselleck e suas contribuições para complexificar o entendimento das relações de temporalidade. A intenção da formação foi possibilitar uma análise das propostas de planejamento dos professores, de maneira a problematizar o conceito de tempo que perpassa a organização das aulas e dos conteúdos escolares. Ao finalizar a aplicação do curso de formação, foi possível observar uma ampliação nos entendimentos dos conceitos de forma a superar o modelo vigente de ensino baseado em uma visão linear e naturalizada de História. / The main objective of this study is to relate the teaching of History, the notions of time and the relations of temporality. The study occurred from the experience of elaborating the course of continuing formation The teaching of History, the notions of time and the relations of temporality and its application with the teachers of the municipal school network of the city of Arroio do Meio/RS. The intention was to discuss theoretical and methodological fundaments in a manner to correlate the topics and qualify the teachers practices in Basic Education. The research was developed based on observation and analysis of the materials produced by the participating teachers and the use of mechanisms from ethnographic studies, like the field notes. In this proposal, the concept of Historical Time was used, based on studies by the historian Reinhart Koselleck and his contributions, in order to complex the understanding of the relations of temporality. The intention of the formation was to make possible an analysis of the teaching plans, in a manner to problematize the concept of time that grounds the organization of classes and the school contents. By finalizing the application of the course of formation, it was possible to observe an enlargement of the understandings of the concepts in order to overcome the current model of teaching based on a linear and naturalized vision of History.

This work reflects on how the Seventh-day Adventist Church meets the challenges of postmodernism, despite itself having its roots deep in the modern era. The first part deals with the origin of the Seventh-day Adventist Church and the development of its dogma. It primarily focuses on the Thomas Reid?s philosophy of common sense and describes the Adventist statements of dogma that are typical of this church and were influenced by the philosophy of common sense. The second part analyses how this church deals with the challenges of the postmodern era. It describes the current categorisation of Adventist theology on the basis of the differing macro-hermeneutic of the individual streams that depend on how they view the relationship between God and time. It also indicates the practical impacts that these various approaches to church praxis lead to. The aim of this work is to be as objective as possible in describing the current situation and show the potential risks and solutions that the church and its members face. In the author?s opinion, an adequate response to the problems of Adventism in the postmodern era can be found in shifting the emphasis to a general Christian perspective and in redefining specifically Adventist teachings.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / A presente tese tem o objetivo de promover uma análise sobre a norma penal brasileira que versa sobre a violenta emoção, com base no estudo teórico da ação criminal passional. Tem por objeto de estudos a discussão sobre a temporalidade psíquica da ação que sustenta as distinções no instituto jurídico da violenta emoção apresentada nos artigos 28; 65, III, c; 121 1 e 129 4 do Código Penal Brasileiro. A partir de uma construção genealógica, buscou-se os antecedentes históricos dessas leis, posteriormente, interpretadas à luz de conceitos psicanalíticos e de contribuições da antropologia social acerca do imaginário cultural que sustenta a eclosão e o julgamento de crimes na esfera amorosa. O método de trabalho consistiu em um estudo teórico de caráter dedutivo-construtivo baseado em fontes oriundas de diferentes campos teórico-práticos e também de consultas abertas feitas a juristas e estudiosos da criminologia. As transformações históricas nos julgamentos indicam uma transposição da antiga indulgência em relação aos criminosos ao atual apelo por recrudescimento das penas, demonstrando que justificar ou punir crimes sob a rubrica da violenta emoção ligados à esfera amorosa representa um sintoma atrelado ao contexto social. O conceito de "violenta emoção" está sujeito a reducionismos teóricos, devido à ênfase dada à dimensão da "culpabilidade consciente" no sistema jurídico, ao predomínio de interpretações ligadas aos aspectos psicofisiológicos do ímpeto, bem como à incipiente atenção dada às condições inconscientes culturalmente determinantes do ato criminal violento em casais. Desse modo, o texto dos referidos artigos pode servir indevidamente à diminuição da pena em crimes envolvendo casais, assim como a devida atenuação pode ser desconsiderada quando a/o ré/u sofre de privações sociais e psíquicas prolongadas constitutivas de um mal-estar passional por vezes dissociado do tempo da ação. Com as limitações apontadas, reconhece-se a importância da existência da referência à violenta emoção enquanto uma atenuante criminal genérica e critica-se a sua aplicação como "privilégio" de diminuição de pena em crimes de ímpeto em casais. O estudo psicanalítico historicizado do tema assevera a necessidade de realçar tanto a responsabilidade subjetiva ligada à atualização de um potencial psicopatológico, mas, também, a responsabilidade social em relação aos crimes passionais, enfatizando a importância de se criar alternativas à resposta penal, buscando promover uma leitura e interpretação cuidadosa dos artigos sobre a violenta emoção no sentido de propiciar melhor entendimento da temporalidade inconsciente inerente a esses crimes. / The following thesis has as its aim the advancement of an analysis of the Brazilian penal norms as they pertain to violent emotion, grounded on the study of the passionate criminal act. Its basis for study is a discussion concerning the psychic temporality of the act that sustains the distinctions within the juridical institution of violent emotion presented in articles 28; 65, III, c; 121 1 et 129 4 of the Brazilian Penal Code. From a genealogical construct, the historical antecedents of such laws were targeted and then interpreted in light of psychoanalytic concepts and contributions from social anthropology regarding the imaginary customs that nourish the profusion and judgment of crimes within the sphere of love. The work method hinged on a theoretical study in the deductive-constructive manner based on sources ranging from different theoretical/practical fields and on open interviews with jurists and specialists on criminology. The historical transformations of the trials indicate a transposition from the old indulgence towards criminals to todays appeals for the harshening of sentences, showing that justifying or punishing crimes of violent emotion in the sphere of love represents a symptom directly linked to a social context. The concept of violent emotion is not immune to theoretical simplifications, given the emphasis placed on the dimensions of conscious culpability within the penal law system, the predominance of interpretations linked to the psychic-physiological aspects of the drive, as well as the incipient weight placed on the unconscious, culturally determinant conditions of the criminal act among couples. In this manner, the text in the referred Articles may unduly serve for the lessening of sentences for crimes involving couples, just as the due attenuation of sentences may be overlooked when the defendant suffers from prolonged social and psychic privations comprised of a discontent often times dissociated from the time of the criminal act. Pointing out such limitations, one must recognize the importance of the existing reference to violent emotion as a generic means for criminal attenuation and criticize its use as a privilege for the lessening of sentences in crimes of impetus among couples. A psychoanalytic, historical study of the theme stresses the need to enhance the subjective responsibility tied to the realization of a psychopathological tendency, yet furthermore enhances the social responsibility in relation to crimes of passion, thus underscoring the importance of providing alternatives to the penal court answer in order to promote a careful interpretation of articles on violent emotion for the better understanding of the unconscious temporality inherent to these crimes in the penal context.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The issue of research on which we focus this study is based on a reflection around the discourse about linguistic knowledge production in/of Brazil in the fifties. Our central scope is in the understanding of temporality and discursive memory that constitute the scientific discourse about language of this conjuncture from the crossing of Linguistics disciplinary field knowledge. We are interested in this crossing, as it refers to a domain not yet institutionalized in the academic Brazilian context and because it was in a period that there were advances in studies around the Portuguese of Brazil. Thus, in our research, it was approached issues that emphasizes how and for to the scientific discourse around language features a combination with knowledge from different fields; seeking to examine, in particular, the operation of the crossing of Knowledge on Linguistics in this discourse, this crossing can be understood through the notion of transverse-speech (cf. Pêcheux, 2009 [1988]). In order to do that, we have as object of study two works by Serafim da Silva Neto: Introdução ao Estudo da Língua Portuguêsa no Brasil, 1st edition, 1950, and Introdução ao Estudo da Filologia Portuguêsa, 1st edition, 1956, which are significant to the situation in question, by inserting at two different times in the 50s. The first one is recognized as the best work about the Portuguese of Brazil, and the second one is considered a guide that was circulated in Language Courses at the time in question (cf. Penha, 2002). In this sense, we wrote in the view of History of Linguistic Ideas, linking it to theoretical and methodological principles of Discourse Analysis from French orientation, as it is developed in Brazil. / A problemática de pesquisa sobre a qual nos debruçamos neste estudo de dissertação volta-se a uma reflexão em torno do discurso sobre a produção do conhecimento linguístico dos anos 50 no/do Brasil. Nosso escopo central está na compreensão da temporalidade e da memória discursiva que constituem o discurso científico sobre a linguagem dessa conjuntura a partir do atravessamento de saberes do campo disciplinar da Linguística. Interessa-nos este atravessamento, pois esse domínio de saber ainda não está institucionalizado no âmbito acadêmico do contexto brasileiro e porque se trata de um período em que se verifica um avanço nos estudos em torno do português do Brasil. Com isso, tratamos, em nossa pesquisa, de questões que enfatizam como e para que o discurso científico em torno da linguagem apresenta uma articulação com saberes de diferentes domínios; buscando analisar, em especial, o funcionamento do atravessamento dos saberes da Linguística nesse discurso, atravessamento este que pode ser compreendido a partir da noção do discurso-transverso (cf. Pêcheux, 2009 [1988]). Para tanto, delimitamos como objeto de estudo duas obras de Serafim da Silva Neto: Introdução ao Estudo da Língua Portuguêsa no Brasil, 1ª edição, de 1950, e Introdução ao Estudo da Filologia Portuguêsa, 1ª edição, de 1956, que são significativas para a conjuntura em questão, inserindo-se em dois momentos distintos dos anos 50. A primeira é reconhecida como a melhor obra sobre o português do Brasil, e a segunda, considerada como um manual que circulou nos cursos superiores de Letras da época em questão (cf. Penha, 2002). Nessa esteira, inscrevemo-nos na perspectiva da História das Ideias Linguísticas, vinculando-a aos pressupostos teórico-metodológicos da Análise de Discurso de orientação francesa, tal como se desenvolve no Brasil.

The political militant from the left-wing is the one that denies the state of current things, recovering a historic experience located far before its time and projecting a future beyond the incessant reproduction of the present relations. We chosen the Landless Workers Movement, not as study object, but as specific place where this consciousness is made and can be comprehended. The historic consciousness study of the landless militancy is, for us, the best starting point to understand the magnification of the historical time operated on the change of social relations lived inside an organization. The time division between before and after, as well as the history being understood as a progress isn t a natural given data, but a construction that obeys the contradictions of the present. It, therefore, must understand how the present lived by the militancy operates changes on the consciousness of time. From documents, reference books, formation notebooks and several materials produced by MST, we try to understand the way that the movement tells his history and lists with this wider experience of the struggle for the change of the current social order. Similarly, when we hear reports of history of several militants, we try to comprehend how this wider narrative re-orients the sight over history himself, over the experience of contradictions on before and after making the landless militant / O trabalho que segue dedica-se ao estudo da viv?ncia do tempo hist?rico pela milit?ncia pol?tica de nosso tempo. O militante pol?tico de esquerda ? aquele que nega o estado de coisas vigente recuperando uma experi?ncia hist?rica situada muito antes de seu tempo e projetando um futuro para al?m da reprodu??o incessante das rela??es do presente. Escolhemos o Movimento dos Trabalhadores Rurais Sem Terra, n?o como objeto de estudo, mas como local espec?fico onde essa consci?ncia ? formada e pode ser compreendida. O estudo da consci?ncia hist?rica da milit?ncia sem terra ?, para n?s, o melhor ponto de partida para entendermos a amplia??o do tempo hist?rico operada na mudan?a das rela??es sociais vividas dentro de uma organiza??o. A divis?o do tempo entre um antes e um depois, bem como a hist?ria entendida como progresso n?o ? um dado natural, mas uma constru??o que obedece ?s contradi??es do presente. Trata-se, portanto, de entender como o presente vivido pela milit?ncia opera mudan?as na consci?ncia do tempo. A partir de documentos, livros de refer?ncia, cadernos de forma??o e diversos materiais produzidos pelo MST, buscamos entender a forma como o movimento conta a sua hist?ria e a relaciona com essa experi?ncia mais ampla da luta pela terra e da luta pela mudan?a da ordem social vigente. Da mesma forma, ao ouvirmos os relatos da hist?ria de diversos militantes, buscamos compreender como essa narrativa mais ampla re-orienta o olhar sobre a pr?pria hist?ria, sobre a viv?ncia das contradi??es no antes e depois do fazer-se militante sem terra
