La traduction des motifs sonores dans les littératures africaines europhones comme réactivation du patrimoine poétique maternel

Plusieurs monographies récentes se sont intéressées à la traduction des littératures africaines europhones (Gyasi 2006, Bandia 2008, Batchelor 2009), faisant valoir le concept d’autotraduction (au sens métaphorique) et insistant sur le fait que ces écritures sont porteuses d’une oralité ou de marques linguistiques issues des langues parlées par les écrivains. Toutefois, la question de l’hybridité comme point de jonction entre littératures orales et écrites a encore rarement été examinée sous un angle poétique et c’est précisément dans cet esprit que cette recherche a été entreprise. Dans un premier temps, à partir des ouvrages originaux de six auteurs, trois d’expression littéraire anglaise (Farah, Hove et Armah) et trois d’expression littéraire française (Waberi, Adiaffi et Djebar), je montre en quoi ces écritures méritent d’être qualifiées de poétiques avant de mettre cette esthétique en relation avec le patrimoine littéraire de chacun des auteurs du corpus; ponctuellement, d’autres affiliations littéraires sont mises en évidence. Cette poétique est examinée dans sa dimension mélopoéique (Pound 1954), c’est-à-dire sous l’angle des structures audibles, appelées aussi figures de style jouant sur la forme phonétique des mots (Klein-Lataud 2001). Dans un second temps, j’examine comment cette poétique sonore a été recréée, tant de manière qualitative que quantitative, dans les traductions de Bardolph, de Richard et de J. et R. Mane (pour les auteurs d’expression anglaise) et de Garane, de Katiyo et de Blair (pour les auteurs d’expression française). Les enjeux associés à la réactivation des structures poétiques sonores sont mis en évidence dans le dernier chapitre qui propose un tour d’horizon des modalités de « consommation » de l’objet littéraire et qui s’achève sur les questions soulevées par la progression du livre audio. La méthodologie élaborée dans ce cadre s’inspire essentiellement de Berman (1995) et de Henry (2003). La conceptualisation de la poétique sonore, telle que mise en œuvre dans le contexte particulier de ces littératures, fait appel aux paradigmes de valence traductive (Folkart 2007) et de traduction métonymique (Tymoczko 1999). Par ailleurs, cette recherche s’appuie sur la récente thèse de doctorat de Fraser (2007) consacrée à la théorisation du sonore en traduction.

Dystrobrevin and dystrophin: An interaction through coiled-coil motifs

Dystrobrevin, a dystrophin-related and -associated protein, has been proposed to be important in the formation and maintenance of the neuromuscular junction. Dystrobrevin coprecipitates with both the acetylcholine receptor complex as well as the dystrophin glycoprotein complex. Although the nature of dystrobrevin’s association with the dystrophin glycoprotein complex remains unclear, it is known that dystrobrevin binds directly to the syntrophins, a heterologous group of dystrophin-associated proteins. Using the yeast two-hybrid system to identify protein–protein interactions, we present evidence for the heterodimerization of dystrobrevin directly with dystrophin. The C terminus of dystrobrevin binds specifically to the C terminus of dystrophin. We further refined this site of interaction to these proteins’ homologous coiled-coil motifs that flank their respective syntrophin-binding sites. We also show that the interaction between the dystrobrevin and dystrophin coiled-coil domains is specific and is not due to a nonspecific coiled-coil domain interaction. From the accumulated evidence of protein–protein interactions presented here and elsewhere, we propose a partially revised model of the organization of the dystrophin-associated glycoprotein complex.

Chain motifs: The tails and handles of complex networks

A great part of the interest in complex networks has been motivated by the presence of structured, frequently nonuniform, connectivity. Because diverse connectivity patterns tend to result in distinct network dynamics, and also because they provide the means to identify and classify several types of complex network, it becomes important to obtain meaningful measurements of the local network topology. In addition to traditional features such as the node degree, clustering coefficient, and shortest path, motifs have been introduced in the literature in order to provide complementary descriptions of the network connectivity. The current work proposes a different type of motif, namely, chains of nodes, that is, sequences of connected nodes with degree 2. These chains have been subdivided into cords, tails, rings, and handles, depending on the type of their extremities (e.g., open or connected). A theoretical analysis of the density of such motifs in random and scale-free networks is described, and an algorithm for identifying these motifs in general networks is presented. The potential of considering chains for network characterization has been illustrated with respect to five categories of real-world networks including 16 cases. Several interesting findings were obtained, including the fact that several chains were observed in real-world networks, especially the world wide web, books, and the power grid. The possibility of chains resulting from incompletely sampled networks is also investigated.

Automatic Network Fingerprinting through Single-Node Motifs

Complex networks have been characterised by their specific connectivity patterns (network motifs), but their building blocks can also be identified and described by node-motifs-a combination of local network features. One technique to identify single node-motifs has been presented by Costa et al. (L. D. F. Costa, F. A. Rodrigues, C. C. Hilgetag, and M. Kaiser, Europhys. Lett., 87, 1, 2009). Here, we first suggest improvements to the method including how its parameters can be determined automatically. Such automatic routines make high-throughput studies of many networks feasible. Second, the new routines are validated in different network-series. Third, we provide an example of how the method can be used to analyse network time-series. In conclusion, we provide a robust method for systematically discovering and classifying characteristic nodes of a network. In contrast to classical motif analysis, our approach can identify individual components (here: nodes) that are specific to a network. Such special nodes, as hubs before, might be found to play critical roles in real-world networks.

Communism and Public Opinion in Queensland, 1939-1951 : An Explanation of Queensland's Vote in the 1951 Anti-Communist Referendum

The starting point of this thesis was a desire to explain the rapid demise in the popularity which the Communist Party enjoyed in Queensland during the second world war. Wartime Queensland gave the Australian Communist Party its highest state vote and six years later Queensland again gave the Communist Party its highest state vote - this time however, to ban the Party. From this I was led into exploring the changing policies, beliefs and strategies of the Party, as well as the many sub-groups on its periphery, and the shifts in public response to these. In 1939 Townsville elected Australia's first Communist alderman. Five years later, Bowen elected not only Australia's first but also the British Empire's first, Communist state government member. Of the five electorates the Australian Communist Party contested in the 1944 Queensland State elections, in none did the Party's candidate receive less than twenty per-cent of the formal vote. Not only was the Party seemingly enjoying considerable popular support but this was occurring in a State which, but for the Depression years (May 1929 - June 1932) had elected a Labor State Government at every state election since 1915. In the September 1951 Constitution Alteration Referendum, 'Powers To Deal With Communists and Communism', Queensland regist¬ered the nation's highest "Yes" majority - 55.76% of the valid vote. Only two other states registered a majority in favour of the referendum's proposals, Western Australia and Tasmania. As this research was undertaken it became evident that while various trends exhibited at the time, anti-Communism, the work of the Industrial Groups, Labor opportunism, local area feelings, ideological shifts of the Party, tactics of Communist-led unions, etc., were present throughout the entire period, they were best seen when divided into three chronological phases of the Party's history and popularity. The first period covers the consolidation of the Party's post-Depression popularity during the war years as it benefited from the Soviet Union's colossal contribution to the Allied war efforts, and this support continued for some six months or so after the war. Throughout the period Communist strength within the trade union movement greatly increased as did total Party membership. The second period was marked by a rapid series of events starting in March 1946, with Winston Churchill's "Official Opening" of the Cold War by his sweeping attack on Communism and Russia, at Fulton. Several days later the first of a series of long and bitter strikes in Communist-led unions occurred, as the Party mobil¬ized for what it believed would be a series of attacks on the working class from a ruling class, defending a capitalist system on the verge of an economic collapse. It was a period when the Party believed this ruling class was using Labor reformism as a last desperate 'carrot' to get workers to accept their lot within a capitalist economic framework. Out of the Meat Strike emerged the Industrial Groups, who waged not only a determined war against Communist trade union leadership but also encouraged the A.W.U.-influenced State Labor apparatus to even greater anti-Communist antagonisms. The Communist Party's increasing militancy and Labor's resistance to it, ended finally in the collapse of the Chifley Labor government. Characteristically the third period opens with the Communist Party making an another about-face, desperately trying to form an alliance with the Labor Party and curbing its former adventurist industrial policy, as it prepared for Menzies' direct assault. The Communist Party's activities were greatly reduced, a function of both a declining member-ship and, furthermore, a membership reluctant to confront an increasingly hostile society. In examining the changing policies, beliefs and strategies of the Party and the shifts in public response to these, I have tried to distinguish between general trends occurring within Australia and the national party, and trends peculiar to Queensland and the Queensland branch of the Party, The Communist Party suffered a decline in support and membership right across Australia throughout this period as a result of the national policies of the Party, and the changing nature of world politics. There were particular features of this decline that were peculiar to Queensland. I have, however, singled out three features of particular importance throughout the period for a short but more specifically detailed analysis, than would be possible in a purely chronological study: i.e. the Party's structure, the Party's ideological subservience to Moscow, and the general effect upon it of the Cold War.

Overlapping motifs in the membrane-proximal region of cytokine receptor accessory and signaling subunits

The membrane-proximal cytoplasmic region of cytokine receptors (CRs) is highly conserved and essential for receptor activation. In particular this region is essential for the activation of members of the Janus family of protein kinases (JAK) which results in initiation of receptor signaling. We have examined the sequence of this region in a number of CR signaling and accessory subunits with a view to better delineating motifs that play an important role in initiating receptor activity. Here, we have delineated two distinct proline-rich motifs in the membrane-proximal domains of cytokine receptors. Their configuration and distribution among CR subunits strongly suggest a model in which the two motifs act in a concerted manner to induce full receptor and JAK activation. (C) 2004 Elsevier Ltd.

Novel gene containing multiple epidermal growth factor-like motifs transiently expressed in the papillae of the ascidian tadpole larvae

We have investigated molecular mechanisms of the embryonic development of an ascidian, a primitive chordate which shares features of both invertebrates and vertebrates, with a view to identifying genes involved in development and metamorphosis, We isolated 12 partial cDNA sequences which were expressed in a stage-specific manner using differential display, We report here the isolation of a full-length cDNA sequence for one of these genes which was specifically expressed during the tailbud and larval stages of ascidian development, This cDNA, 1213 bp in length, is predicted to encode a protein of 337 amino acids containing four epidermal growth factor (EGF)-like repeats and three novel cysteine-rich repeats, Characterization of its spatial expression pattern by in situ hybridisation in late tailbud and larval embryos demonstrated strong expression localised throughout the papillae and anteriormost trunk and weaker expression in the epidermis of the remainder of the embryo, As recent evidence indicates that the signal for metamorphosis originates in the anterior trunk region, these results suggest that this gene may have a role in signalling the initiation of metamorphosis.

A disciplina de história da educação em perspectiva histórica : da Faculdade de Filosofia, Ciências e Letras à Universidade Federal do Espírito Santo (1951-2000)

A pesquisa analisa da constituição histórica da disciplina História da Educação ministrada na Faculdade de Filosofia Ciências e Letras do Estado do Espírito Santo, posteriormente incorporada a Universidade Federal do Espírito Santo entre os anos de 1951 e 2000. Investiga a constituição histórica da disciplina, as transformações programáticas, legais e institucionais referentes à disciplina de História da Educação, como também as abordagens historiográficas, periodizações e os conceitos de tempo, história e educação. A fundamentação teórica e metodológica articula-se dialogicamente a partir das construções conceituais e metodológicas de Carlo Ginzburg e Mikhail Bakhtin. A partir dos conceitos de polifonia e dialogismo, comum a ambos, investigou-se as vozes e diálogos impressos nas narrativas da disciplina de História da Educação e seu ensino, sejam em camadas mais superficiais ou profundas, encontradas no corpus documental consultado e analisado, que correspondem a: programas de ensino, transparências, leis, estruturas curriculares, documentos de departamento; resenhas e fichamentos de textos, bibliografia obrigatória e complementar, avaliações e entrevistas. Procurou-se no corpus documental dados aparentemente negligenciáveis – pistas, indícios e sinais – remontar uma realidade histórica complexa e não experimentável diretamente. Ao investigar historicamente a trajetória da disciplina História da Educação e seu ensino a partir dos parâmetros legais, programáticos e institucionais, foi possível perceber que as mudanças mais profundas operadas na disciplina não se originam das legislações e reestruturações curriculares, mas dos locais de produção e socialização do conhecimento histórico. Durante o período analisado, as duas esferas de produção historiográficas que mais influenciaram nas abordagens, periodizações e conceitos de tempo, história e educação da disciplina História da Educação do curso de pedagogia pesquisado foram: a editora responsável pela publicação e divulgação dos Manuais de História da Educação da coleção Atualidades Pedagógicas (1951-1979) e os Programas de Pós-graduação em Educação e História (1980 - 2000). Entre 1951 e finais de 1970 observa-se a influência dos Manuais de História da Educação, na organização e programação do ensino de História da Educação e uma abordagem filosófica voltada para a história das ideias pedagógicas e análises do pensamento de filósofos e educadores sobre a educação e respectivas inserções em doutrinas filosóficas europeias. A partir de 1980 as abordagens de cunho econômico, político e ideológico dos contextos históricos educativos passaram a predominar nos programas de ensino das disciplinas de História da Educação I e II, e vigoraram até meados nos anos de 1990. Na disciplina de História da Educação I a abordagem é marcada por análises do contexto de produção e organização das classes sociais; com relação à disciplina História da Educação II, até meados de 1995, trata da educação brasileira. A partir da abordagem fundamentada na Teoria da Dependência após 1995, os documentos consultados começam a mostrar outras marcas que sugerem uma abordagem voltada para a dimensão política e social, abordando a História da Educação Brasileira, a partir dos movimentos sociais e seus respectivos projetos educacionais.

Classificação de sons cardíacos usando Motifs: desenvolvimento de uma aplicação móvel

Este documento foi redigido no âmbito da Tese, do Mestrado em Engenharia Informática na área de Tecnologias do Conhecimento e Decisão, do Departamento de Engenharia Informática, do ISEP, cujo tema é classificação de sons cardíacos usando motifs. Neste trabalho, apresenta-se um algoritmo de classificação de sons cardíacos, capaz de identificar patologias cardíacas. A classificação do som cardíaco é um trabalho desafiante dada a dificuldade em separar os sons ambiente (vozes, respiração, contacto do microfone com superfícies como pele ou tecidos) ou de ruído dos batimentos cardíacos. Esta abordagem seguiu a metodologia de descoberta de padrões SAX (motifs) mais frequentes, em séries temporais relacionando-os com a ocorrência sistólica (S1) e a ocorrência diastólica (S2) do coração. A metodologia seguida mostrou-se eficaz a distinguir sons normais de sons correspondentes a patologia. Os resultados foram publicados na conferência internacional IDEAS’14 [Oliveira, 2014], em Julho deste ano. Numa fase seguinte, desenvolveu-se uma aplicação móvel, capaz de captar os batimentos cardíacos, de os tratar e os classificar. A classificação dos sons é feita usando o método referido no parágrafo anterior. A aplicação móvel, depois de tratar os sons, envia-os para um servidor, onde o programa de classificação é executado, e recebe a resposta da classificação. É também descrita a arquitetura aplicacional desenhada e as componentes que a constituem, as ferramentas e tecnologias utilizadas.

Classificação de sons urbanos usando motifs e MFCC

A classificação automática de sons urbanos é importante para o monitoramento ambiental. Este trabalho apresenta uma nova metodologia para classificar sons urbanos, que se baseia na descoberta de padrões frequentes (motifs) nos sinais sonoros e utiliza-los como atributos para a classificação. Para extrair os motifs é utilizado um método de descoberta multi-resolução baseada em SAX. Para a classificação são usadas árvores de decisão e SVMs. Esta nova metodologia é comparada com outra bastante utilizada baseada em MFCC. Para a realização de experiências foi utilizado o dataset UrbanSound disponível publicamente. Realizadas as experiências, foi possível concluir que os atributos motif são melhores que os MFCC a discriminar sons com timbres semelhantes e que os melhores resultados são conseguidos com ambos os tipos de atributos combinados. Neste trabalho foi também desenvolvida uma aplicação móvel para Android que permite utilizar os métodos de classificação desenvolvidos num contexto de vida real e expandir o dataset.
