Nosso objetivo neste trabalho é analisarmos a construção e as transformações da ideia de história do antropólogo norte-americano Marshall Sahlins, entre as décadas de 1950 e 1980. Acreditamos que este período é importante pelo fato de encontrarmos nele os princípios de uma forma de pensar a história que continuará a dominar a obra de Sahlins nas décadas seguintes. Para analisarmos sua ideia de história, bem como suas transformações, interpretaremos os princípios teóricos que a define enquanto tal. Argumentaremos que Sahlins adotará duas ideias de história durante este período: uma que terá a palavra "evolução" como princípio teórico central e outra em que os termos "cultura" e "estrutura" serão seus princípios teóricos mais importantes. Estas ideias de história serão analisadas também no contexto da sociedade e das ideias que tiveram um papel central na vida intelectual de Sahlins. Defenderemos também que, neste contexto, as obras dos antropólogos Leslie White e Claude Lévi-Strauss terão uma grande importância. E esperamos, deste modo, dar duas contribuições: uma para a compreensão da ideia de história de Sahlins; e outra para o atual debate sobre a relação entre História e Antropologia. / Our objective in this work is to analyze the construction and the transformations of the idea of history of the American anthropologist Marshall Sahlins, between de decades of 1950 and 1980. We believe that this period is important because we can find in it the principles of a way of thinking about history that will continue to dominate Sahlins work in the following decades. In order to analyze his idea of history, as well as its transformations, we will interpret the theoretical principles that define it as such. We will argue that Sahlins will adopt two ideas of history during this period: one that will have the word "evolution" as its central theoretical principle and another where the words "culture" and "structure" will be its most important theoretical principles. These ideas of history will also be analyzed in the context of the society and the ideas that had a central role in Sahlins intellectual life. We will also defend that, in this context, the works of Leslie White and Claude Lévi-Strauss will have a great importance. And we hope, in this way, to give two contributions: one for the understanding of Sahlins idea of history; and another to the current debate about the relationship between History and Anthropology.

Esta dissertação trata de duas obras autobiográficas escritas por autoras nativas que ganharam reconhecimento na década de 70: Bobbi Lee Indian Rebel (1975), da nativo-canadense Lee Maracle, e The Turquoise Ledge: a Memoir (2010), da nativo-americana Leslie Marmon Silko. A importância destas autoras para a Renascença Nativo-Americana/Canadense é inegável, e cada uma delas contribuiu fazendo uso de estratégias diferentes: enquanto Maracle começou sua carreira com Bobbi Lee Indian Rebel, de cunho autobiográfico, Silko esperou mais de trinta anos para publicar The Turquoise Ledge. A problematização de se ver estas obras pelo olhar estritamente ocidental, ou estritamente nativo, é discutida, assim como o aparentemente inevitável tom político dessas narrativas. Ainda que mais de três décadas separem a publicação das obras selecionadas, perguntas como: Estas obras podem ser consideradas literatura?, Elas têm como principal propósito engrandecer feitos pessoais das autoras?, ou Como essas narrativas contribuem para o empoderamento do povo Nativo? podem nunca chegar a serem respondidas, mas, de fato, incitaram a escrita desta dissertação e nortearam nossa análise / This dissertation brings to the fore two autobiographical works by Native women authors who first gained recognition in the 1970s: Bobbi Lee Indian Rebel (1975), by Native-Canadian Lee Maracle and The Turquoise Ledge: a Memoir (2010), by Native-American Leslie Marmon Silko. These womens undeniable importance to the Native American/Canadian Renaissance is clear, and each of these authors decided to contribute to Native literature using different strategies: while Maracle started her career with Bobbi Lee Indian Rebel, an autobiographical work, Silko waited over thirty years to publish her The Turquoise Ledge. The problematization of seeing either works strictly through Western or strictly through Native perspectives is also addressed here, along with the apparently inevitable political tone present in both narratives. Despite the fact that the two selected works have been written over three decades apart, questions such as: Can these works be considered literature?, Do they have as main purpose to highlight the authors personal accomplishments? or How do they work to empower the Native people? may never be answered, but they did incite the writing of this dissertation and guided our analysis

"Storied Voices in Native American Texts: Harry Robinson, Thomas King, James Welch and Leslie Marmon Silko" approaches Native American literatures from within an interdisciplinary framework that complicates traditional notions o f literary "origins" and canon. It situates the discussion of Native literatures in a Native American context, suggesting that contemporary Native American writing has its roots in Native oral storytelling traditions. Each of these authors draws on specific stories and histories from his or her Native culture. They also draw on European elements and contexts because these are now part o f Native American experience. I suggest that Native oral tradition is already inherently novelistic, and the stories that lie behind contemporary Native American writing explicitly connect past and present as aspects o f current Native reality. Contemporary Native American writers are continuing an on-going and vital storytelling tradition through written forms. A comparison of the texts o f a traditional Native storyteller, Robinson, with the highly literate novels of King, Welch and Silko, shows how orally told stories connect with the process o f writing. Robinson's storytelling suggests how these stories "theorize" the world as he experiences it; the Native American novel continues to theorize Native experience in contemporary times. Native writers use culturally specific stories to express an on-going Native history. Their novels require readers to examine their assumptions about who is telling whose story, and the traditional distinctions made between fact and fiction, history and story. King's Green Grass. Running Water takes stories from Western European literary traditions and Judeao-Christian mythology and presents them as part of a Native creation story. Welch's novel Fools Crow re-writes a particular episode from history, the Marias River Massacre, from a Blackfeet perspective. Silko's Almanac of the Dead recreates the Mayan creation story o f the Popol Vuh in the context o f twentiethcentury American culture. Each of these authors maintains the dialogic fluidity of oral storytelling performance in written forms and suggests that stories not only reflect the world, but that they create it in the way that Robinson understands storytelling as a form of theory. / Arts, Faculty of / English, Department of / Graduate

An examination of the influences on twentieth-century wind music would be incomplete without the consideration of composer, organist, pianist, conductor, teacher, and critic Nadia Boulanger (1887-1979). Students from the United States began studying with Boulanger between World War I and World War II, and continued to travel to study with her for over fifty years. The respect awarded this legendary French woman was gained as a result of her effectiveness as a teacher, her influence on the development of each student's unique compositional style, and her guidance of an emerging American musical style. The correlation between the teacher's lessons and the compositional output of her students must be explored. Boulanger did not compose specifically for winds, and she did not encourage her students to compose for the wind symphony. However, this document will outline the influence that this powerful pedagogue exerted over the creation of repertoire by her students by providing insight into the pedagogical style and philosophical foundations of Boulanger as reflected in the literature and by the writings, comments, and compositions of three successful students who composed literature for the wind symphony: Aaron Copland (1900-1990), Leslie Bassett (b. 1923), and Donald Grantham (b. 1947). Three significant works for winds will be considered including Copland's Emblems, Bassett's Lullaby for Kirsten, and Grantham's Variations on an American Cavalry Song.

Dans le cadre de cette thèse, on s'intéresse à la dynamique de quelques fluides complexes. D'une part on étudie la dynamique des cristaux liquides nématiques, en utilisant les modèles proposés par Ericksen et Leslie, Beris et Edwards, Qian et Sheng. D'autre part, on analyse un fluide complexe dont la dynamique dépend de la température et qui est modélisée par le système de Boussinesq. Les cristaux liquides sont des matériaux avec une phase de la matière intermédiaire entre les liquides et les solides qui sont des phases plus connues. Dans cette thèse, on s'intéresse à l'étude du problème de Cauchy associé à chaque système modélisant leurs hydrodynamiques. Tout d'abord on obtient des résultats d'existence et d'unicité de solutions faibles ou classiques, solutions qui sont globales en temps. Ensuite, on analyse la propagation de la régularité des données initiales pour ces solutions. Le cadre fonctionnel adopté pour les données initiales est celui des espaces de Besov homogènes, généralisant des classes d'espaces mieux connues : les espaces de Soboloev homogènes et les espaces de Hölder. Le système Ericksen-Leslie est considéré dans la version simplifiée proposée par F. Lin et C. Liu, version qui préserve les principales difficultés du système initial. On étudie ce problème en dimension supérieure ou égale à deux. On considère le système dans le cas inhomogène, c'est-à dire avec une densité variable. De plus, on s'intéresse au cas d'une densité de faible régularité qui est autorisée à présenter des discontinuités. Donc, le résultat que l'on démontre peut être mis en relation avec la dynamique des mélanges de nématiques non miscibles. On démontre l'existence globale en temps de solutions faibles de régularité invariante par changement d'échelle, en supposant une condition de petitesse sur les données initiales dans des espaces de Besov critiques. On démontre aussi l'unicité de ces solutions si de plus on suppose une condition supplémentaire de régularité pour les données initiales. Le système Beris-Edwards est analysé dans le cas bidimensionnel. On obtient l'existence et l'unicité de solutions faibles globales en temps, lorsque les données initiales sont dans des espaces de Sobolev spécifiques (sans condition de petitesse). Le niveau de régularité de ces espaces fonctionnels est adapté pour bien définir les solutions faibles. L'unicité est une question délicate et demande une estimation doublement logarithmique pour une norme sur la différence entre deux solutions dans un espace de Banach convenable. Le lemme d'Osgood permet alors de conclure à l'unicité de la solution. On obtient également un résultat de propagation de régularité d'indice positif. Afin de prendre en compte l'inertie des molécules, on considère aussi le modèle proposé par Qian et Sheng, et on étudie le cas de la dimension supérieure ou égale à deux. Ce système montre une caractéristique structurale spécifique, plus précisément la présence d'un terme inertiel, ce qui génère des difficultés significatives. On démontre l'existence d'une fonctionnelle de Lyapunov et l'existence et l'unicité de solutions classiques globales en temps, en considérant des données initiales petites. Enfin, on analyse le système de Boussinesq et on montre l'existence et l'unicité de solutions globales en temps. On considère la viscosité en fonction de la température en supposant simplement que la température initiale soit bornée, tandis que la vitesse initiale est dans des espaces de Besov avec indice de régularité critique. Les données initiales ont une composante verticale grande et satisfont à une condition de petitesse spécifique sur les composantes horizontales: elles doivent être exponentiellement petites par rapport à la composante verticale. / The present thesis is devoted to the dynamics of specific complex fluids. On the one hand we studythe dynamics of the so-called nematic liquid crystals, through the models proposed by Ericksen and Leslie, Beris and Edwards, Qian and Sheng.On the other hand we analyze the dynamics of a temperature-dependent complex fluid, whose dynamics is governed by the Boussinesq system.Nematic liquid crystals are materials exhibiting a state of matter between an ordinary fluid and a solid. In this thesis we are interested in studying the Cauchy problem associated to eachsystem modelling their hydrodynamics. At first, we establish some well-posedness results, such asexistence and uniqueness of global-in-time weak or classical solutions. Moreover we also analyzesome dynamical behaviours of these solutions, such as propagations of both higher and lowerregularities.The general framework for the initial data is that of Besov spaces, which extend the most widelyknown classes of Sobolev and Hölder spaces.The Ericksen-Leslie system is studied in a simplified form proposed by F. Lin and C. Liu,which retains the main difficulties of the original one. We consider both a two-dimensional and athree-dimensional space-domain. We assume the density to be no constant, i.e. the inhomogeneouscase, moreover we allow it to present discontinuities along an interface so that we can describe amixture of liquid crystal materials with different densities. We prove the existence of global-in-timeweak solutions under smallness conditions on the initial data in critical homogeneous Besov spaces.These solutions are invariant under the scaling behaviour of the system. We also show that theuniqueness holds under a tiny extra-regularity for the initial data.The Beris-Edwards system is analyzed in a two-dimensional space-domain. We achieve existenceand uniqueness of global-in-time weak solutions when the initial data belongs to specific Sobolevspaces (without any smallness condition). The regularity of these functional spaces is suitable inorder to well define a weak solution. We achieve the uniqueness result through a specific analysis,controlling the norm of the difference between to weak solutions and performing a delicate doublelogarithmicestimate. Then, the uniqueness holds thanks to the Osgood lemma. We also achieve aresult about regularity propagation.The Qian-Sheng model is analyzed in a space-domain with dimension greater or equal than two.In this case, we emphasize some important characteristics of the system, especially the presence ofan inertial term, which generates significant difficulties. We perform the existence of a Lyapunovfunctional and the existence and uniqueness of classical solutions under a smallness condition forthe initial data.Finally we deal with the well-posedness of the Boussinesq system. We prove the existence ofglobal-in-time weak solutions when the space-domain has a dimension greater or equal than two.We deal with the case of a viscosity dependent on the temperature. The initial temperature is justsupposed to be bounded, while the initial velocity belongs to some critical Besov Space. The initialdata have a large vertical component while the horizontal components fulfil a specific smallnessconditions: they are exponentially smaller than the vertical component.

La présente recherche a pour but de procéder à une étude comparative du processus régénératif au cœur de deux romans phares de la fiction autochtone contemporaine, soit Ceremony de Leslie Marmon Silko et Green Grass, Running Water de Thomas King. Trois volets principaux sont examinés : le rôle de la nature en tant que référent culturel dans le processus de régénération des personnages principaux de chaque roman, l’évolution de la quête identitaire dans un environnement post-contact, ainsi que les répercussions de la réactualisation de l’identité de chaque protagoniste sur la communauté à laquelle il appartient. Cette comparaison entre les procédés employés par Silko et King permettront, en un premier temps, d’identifier des éléments de continuité entre les deux auteurs. Ces similarités incluent la centralité de la nature dans la reconnexion des protagonistes avec leur culture et leur identité ainsi que l’emphase sur la nécessité d’une identité hybride dans un environnement post-contact. De plus, la comparaison entre ces deux auteurs issus de deux contextes socio-historiques distincts permet d’isoler certains éléments du contexte propre à chaque roman afin de déterminer le rôle de la réalité autochtone sur la fiction produite à chaque époque. De façon plus spécifique, il sera entre autres question de l’influence de la montée du mouvement environnementaliste euro-américain sur la valeur symbolique du retour à la nature, ainsi que de l’importance grandissante de la classe moyenne autochtone éduquée et de la façon dont ce nouveau phénomène est exprimé dans l’œuvre de King. / This thesis compares the regenerative processes at the heart of two milestone novels of contemporary Native American literature, Leslie Marmon Silko’s Ceremony and Thomas King’s Green Grass, Running Water. My comparative study will be divided into three main sections: the role of nature as a cultural referent in the main characters’ regenerative processes in each novel, the evolution of the identity quest in a post-contact environment, and finally, the repercussions of the protagonists’ re-actualization of identity on the rest of their community. Through the comparative study of the processes employed by Silko and King with respect to one’s relationship to nature, cultural identity and social relations, I will be able to identify several similarities shared by the two novels, which demonstrate that they belong to the same Native artistic continuum. These resemblances include the central role of nature in reconnecting the protagonists to their identity, as well as a predominant emphasis on the emergence of a hybridized identity in a post-contact environment. Moreover, the comparison of two novels emerging from two different eras of Native American Literature –that of the 1970s and of the 1990s- will allow me to isolate the influence of the cultural context to which each particular work belongs. In doing so, it becomes possible to determine the influence of some transformations in Native lifestyle on the fiction produced at a given time. More specifically, the modifications I chose to focus on include the rise of Euro-American environmentalism on the symbolic value of returning to nature for Natives as well as the increasing presence of middle-class, educated Natives and their representation, mostly present in King’s fiction.

This PhD comprises a work of fiction and a dissertation, both of which explore childhood, children and parenthood. The Imagined Child, the novel, closely examines the nature of parenthood, the expectations inherent in the parent-child relationship, and the responsibilities that society imposes on parents. It explores the strains of guilt and blame that surround all primary relationships: every child is damaged in some way – through nature and nurture. How they deal with that damage determines the kinds of adults – and ultimately the kinds of parents – they become. The dissertation approaches childhood as a literary device. It explores the ways in which four novelists from different historical periods have characterised and thematised childhood. It presents ‘childhood’ as a social construct and considers the ways in which childhood and parenting have changed in recent, Western history. It then focuses on the research into and literary representations of children in Africa to explore the versions of childhood inherited by African, and particularly South African, children and how this differs from American or European models. Textual analysis was employed to examine the representation of childhood in four texts: Charles Dickens’s David Copperfield (1850), L.P. Hartley’s The Go-Between (1953), Harper Lee’s To Kill a Mockingbird (1960), and Michiel Heyns’s The Children’s Day (2002). An examination of research and literature shows a very different trajectory for childhood in Africa than in Europe, and reveals that childhood on the continent has never been consistent, in life or literature. There is, in other words, no universal “African childhood”. The literary children of South Africa are examined not only to show how differently childhood is experienced in diverse segments of society, but also to measure the temperature of the times. The differing versions of literary childhood, and their varying treatments, provide a gauge for the zeitgeist in South African society from the 1990s. The dissertation argues that an examination of literary children provides insight into the development of a new democracy. The dissertation and the novel, taken together, suggest that through the real and imagined children of literature can be gained a sense of ourselves.

Ecocritical theology relates to American fiction as it connects nature and spirituality. In my development of the term “neo-pastoral” I begin with Virgil’s Eclogues to serve as examples for spiritual and nature related themes. Virgil’s characters in “The Dispossessed” represent people’s alienation from the land. Meliboeus must leave his homeland because the Roman government has reassigned it to their war veterans. As he leaves Meliboeus wonders why fate has rendered this judgment on him and yet has granted his friend Tityrus a reprieve. Typically, pastoral literature represents people’s longing to leave the city and return to the spiritual respite of the country. When Meliboeus begins his journey he does not travel toward a specific geographical location. Because the gods have forced him from his land and severed his spiritual connection to nature he travels into the unknown. This is the starting point from which I develop neo-pastoral threads in contemporary literature and discuss the alienation that people experience when they are no longer connected to a spirit of the land or genius loci. Neo-pastoralism relates Bakhtin’s idea of chronotope and the expansion of the narrative voice of the novel to include the time/space dialogic. Neo-pastoral fiction shows people in their quest to find spirituality in spite of damage from chemical catastrophic events and suggests they may turn to technology as an ideological base to replace religion. The (anti) heroes of this genre often feel no connection with Judeo-Christian canon yet they do not consider other models of spirituality. Through catastrophes related to the atomic bomb, nuclear waste accidents, and the realization of how chemical pollutants affect the atmosphere, neo-pastoral literature explores the idea of apocalypticism in the event of mass annihilation and the need for canonical reformation. The novels explored in this dissertation are John Updike’s Rabbit, Run; Thomas Pynchon’s The Crying of Lot 49; Bernard Malamud’s The Fixer; Don DeLillo’s White Noise; Leslie Marmon Silko’s Almanac of the Dead; Toni Morrison’s Paradise; and Cormac McCarthy’s The Road.
