The research done in this study was motivated by the notion that individuals (or societies) create their own reality through the specific space they occupy at a certain moment in time. This concept of reality implies an "interspace" between (con)texts that could be described as a hybrid (a term that is used to describe the mixing or intermingling of different aspects or liminal space between various (con)texts. As the notion of identity is closely related to the interaction of the individual with a specific context, the main aim of the research was to promote hybridity as a form of identity by exploring the relationship or dialogue between literature (novel) and film as texts. For this purpose, a comparison was made between the formation of identity in the novel Great Expectations by Charles Dickens and its twentieth century counterpart in film produced by Twentieth Century Fox (directed by Alfonso Cuaron and adapted by Mitch Glazer). The main difference between the two texts, the different periods in which the works were produced, constituted an important point of departure for this study. It also revealed that the main character of the respective texts, Pip/Finn, possesses a type of "core personality" of a sense of values that refuses to be repressed, despite the character's interaction with context as reflected in the interplay between the similarities and differences between the texts. The methodological approach was based on the Brockmeier model which suggested an imbrication of theories such as narratology, semiotics and intertextuality that could all contribute, in some way, towards the formation of "textual" identity. The analysis ,first identified three (con)textual aspects/constants in the formation of identity, namely ideological influences, strategies of writing and social reality, in the novel Great Expectations, and then proceeded to illustrate the transformation of these contextual markers in the twentieth century film version. 'The comparison indicated an expansion of the narrator's/protagonist's historic consciousness in the film that correlated with the cultural dominants of the specific time: the film's realist mode as opposed to the postmodernist expansion or fusion of boundaries. The two texts were perceived to be engaged in a dialogue with no conclusive interpretation, an aspect familiar to the postmodernist approach. / Thesis (Ph.D. (English))--North-West University, Potchefstroom Campus, 2008.

De légendaires, les grandes figures féminines des mythes anciens sont devenues, au fil du XIXe siècle, emblématiques. Le mouvement s’amplifie vers la fin du siècle et l’imaginaire « féminin » se nourrit alors d’un discours social qui contribue à construire la féminité en termes de menace et de dépravation. Les figures mythiques prêteront leurs traits à celle de la femme fatale, devenue le symbole de la dégénérescence de la société française. Engrangeant dans son corps représenté tous les vices du siècle, la figure féminine nous est apparue éminemment révélatrice quant à la compréhension d’une époque. Or, la figure de la femme fatale s’avère fondamentalement ambivalente et Lilith, pouvant à la fois incarner l’amour et la destruction, affiche ce double visage de la féminité. Nous démontrons qu’il existe une relation étroite entre la profonde ambivalence du mythe de Lilith et les représentations de la femme fatale et pour ce faire, procédons à une analyse comparative de l’œuvre de Rachilde et Octave Mirbeau qui, dans La Jongleuse et Le Jardin des supplices, réécrivent le mythe de Lilith. De la comparaison des deux Lilith, ressortent deux représentations extrêmement contrastées de la femme fatale : alors que Rachilde dresse toute droite son héroïne dans son désir ascensionnel, Mirbeau construit une Clara toute en mollesse et assoiffée de chair. Par l’analyse des rapports qui s’articulent entre deux écritures, nous démontrons que la dualité inhérente au mythe de Lilith répond à l’instabilité d’une société aux prises avec de multiples angoisses en matière d’identité sexuelle. Cette comparaison nous amène aussi à nous interroger quant aux traces d’une certaine sexuation dans la voix littéraire. / Over the course of the nineteenth century the legendary female figures of ancient myth had become emblematic of the female sex. This association grew stronger toward the end of the century and the “feminine imaginary” fed itself on a social discourse that contributed to the construction of femininity in terms of menace and depravity. The mythical figures that lent their faces to representations of the femme fatale became symbols of the degeneration of French society. With all of the vices of the century gathered into her body, this female figure appears to us as eminently revealing as to the understanding of an era. However, the figure of the femme fatale is fundamentally ambivalent, and the mythical figure of Lilith, which can embody love as well as destruction, represents the two opposing aspects of nineteenth century representations of femininity. This study shows that there is a direct relationship between the profound ambivalence that characterizes the myth of Lilith and representations of the femme fatale. To this end, we undertake a comparative analysis of the works of Rachilde and Octave Mirbeau, who rewrite the myth of Lilith in The Juggler and The Torture Garden. Two extremely contrasting representations emerge from the comparison between the two “Liliths”: as Rachilde portrays her upstanding heroine’s desire to transcend her body, Mirbeau constructs his Clara as soft and mired in the body, thirsty for carnal pleasure. By examining the relationships that become apparent between these works, we demonstrate that the duality inherent in the myth of Lilith responds to the instability of a society grappling with multiple anxieties regarding sexual identity. This comparison, therefore, allows us to interrogate the traces of a specific mode of sexuation in the literary voice.

Data is being published in digital formats at very high rates nowadays. A large share of this data has complex structure, typically organized as trees (Web documents such as HTML and XML being the most representative) or graphs (in particular, graph-structured Semantic Web databases, expressed in RDF). There is great interest in exploiting such complex data, whether in an Open Data access model or within companies owning it, and efficiently doing so for large data volumes remains challenging. Materialized views have long been used to obtain significant performance improvements when processing queries. The principle is that a view stores pre-computed results that can be used to evaluate (possibly part of) a query. Adapting materialized view techniques to the Web data setting we consider is particularly challenging due to the structural and semantic complexity of the data. This thesis tackles two problems in the broad context of materialized view-based management of Web data. First, we focus on the problem of view selection for RDF query workloads. We present a novel algorithm, which, based on a query workload, proposes the most appropriate views to be materialized in the database, in order to minimize the combined cost of query evaluation, view maintenance and view storage. Although RDF query workloads typically feature many joins, hampering the view selection process, our algorithm scales to hundreds of queries, a number unattained by existing approaches. Furthermore, we propose new techniques to account for the implicit data that can be derived by the RDF Schemas and which further complicate the view selection process. The second contribution of our work concerns query rewriting based on materialized XML views. We start by identifying an expressive dialect of XQuery, corresponding to tree patterns with value joins, and study some important properties for these queries, such as containment and minimization. Based on these notions, we consider the problem of finding minimal equivalent rewritings of a query expressed in this dialect, using materialized views expressed in the same dialect, and provide a sound and complete algorithm for that purpose. Our work extends the state of the art by allowing each pattern node to return a set of attributes, supporting value joins in the patterns, and considering rewritings which combine many views. Finally, we show how our view-based query rewriting algorithm can be applied in a distributed setting, in order to efficiently disseminate corpora of XML documents carrying RDF annotations.

Graph-structured data (GSD) is a popular model to represent complex information in a wide variety of applications such as social networks, biological data management, digital libraries, and traffic networks. The flexibility of this model allows the information to evolve and easily integrate with heterogeneous data from many sources. In this dissertation we study three important problems on GSD. A consistent theme of our work is the use of automata methods and techniques to process and reason about GSD. First, we address the problem of answering queries on GSD in a distributed environment. We focus on regular path queries (RPQs) – given by regular expressions matching paths in graph-data. RPQs are the building blocks of almost any mechanism for querying GSD. We present a fault-tolerant, message-efficient, and truly distributed algorithm for answering RPQs. Our algorithm works for the larger class of weighted RPQs on weighted GSDs. Second, we consider the problem of answering RPQs on incomplete GSD, where different data sources are represented by materialized database views. We explore the connection between “certain answers” (CAs) and answers obtained from “view-based rewritings” (VBRs) for RPQs. CAs are answers that can be obtained on each database consistent with the views. Computing all of CAs for RPQs is NP-hard, and one has to resort to an exponential algorithm in the size of the data–view materializations. On the other hand, VBRs are query reformulations in terms of the view definitions. They can be used to obtain query answers in polynomial time in the size of the data. These answers are CAs, but unfortunately for RPQs, not all of the CAs can be obtained in this way. In this work, we show the surprising result that for RPQs under local semantics, using VBRs to answer RPQs gives all the CAs. The importance of this result is that under such semantics, the CAs can be obtained in polynomial time in the size of the data. Third, we focus on XML–an important special case of GSD. The scenario we consider is streaming XML between exchanging parties. The problem we study is flexible validation of streaming XML under the realistic assumption that the schemas of the exchanging parties evolve, and thus diverge from one another. We represent schemas by using Visibly Pushdown Automata (VPAs), which recognize Visibly Pushdown Languages (VPLs). We model evolution for XML by defining formal language operators on VPLs. We show that VPLs are closed under the defined language operators and this enables us to expand the schemas (for XML) in order to account for flexible or constrained evolution. / Graduate

Néstor Perlongher (1949 Buenos Aires - 1992 Sao Paulo) est l'auteur d'une oeuvre poétique aussi impressionnante par ses thèmes que par son style. Sa poétique est fondée sur des opérations linguistiques variées tels qu'une mixité des niveaux de langue, l'utilisation des jargons et des argots régionaux, l'exaltation du pouvoir suggestif du son, la prolifération des références ambiguës dans le cadre d'une esthétique néobaroque, entre autres. Nous estimons que son oeuvre constitue un des travaux les plus intéressants dans le domaine de l'écriture néo-baroque argentine, tant par la radicalité de son travail avec la matérialité du signe linguistique que par la construction d'une poétique qu'actualise les valeurs esthétiques néo-baroques en les combinant avec des faits historiques et épiques. Cette étude propose de lire l'oeuvre de Néstor Perlongher à la lumière des concepts théoriques en provenance du néo-baroque cubain, ainsi que des ouvrages issus de philosophes poststructuralistes. L'analyse de cette problématique sera faite moyennant l'identification et la description des opérations symboliques et sémantiques que constitue le processus d'artificialisation de l'énoncé et qui finalement permettent l'inscription de ces oeuvres dans le style « néobarroso ». / Néstor Perlongher (1949 Buenos Aires - Sao Paulo in 1992) is the author of a work of impressive themes and tones. His poetry is based on various linguistic operations such as mixing levels of language, the use of jargon and regional slang, the exaltation of the suggestive power of sound, the proliferation of ambiguous references in the context of an aesthetic Neo-Baroque, among others. We believe that his writing is one of the most interesting work in the field of literature Argentine neo-baroque, considering that his work is radical to the materiality of the linguistic sign and build a vision that combines neo-baroque aesthetics with historical facts. This study proposes to read the work of Nestor Perlongher in the light of the theoretical concepts of the Cuban neo-baroque and post-structuralist philosophers. The analysis of this issue is made through the identification and description of the symbolic and semantic operations of artificiality process that allows the inclusion of these works in the style "neobarroso".

The proposed method allows the composition designer to concentrate on high-level specifi- cations, in order to increase productivity and generate specifications that are independent of specific web services. We consider service orchestrations, that is compositions where a central process coordinates all the operations of the application.

[pt] O presente trabalho tem como objetivo evidenciar, sobretudo, nos romances O Evangelho segundo Jesus Cristo e Caim o que nomeamos de teologia ficcional de José Saramago e como ela liga-se à temas da reflexão teológica. Inicialmente, é preciso percorrer um caminho que torne possível afirmar a literatura como autêntica expressão teológica mesmo em formato não teórico. Assim, discute-se a relação entre os dois saberes na história, aproximações e distanciamentos. No entanto, verifica-se a necessidade de afunilar a discussão em torno da ficção romanesca buscando demonstrar o seu potencial teológico. Com este pano de fundo, adentra-se o universo saramaguiano procurando desvendar como se dá a sua construção. Tendo o ateísmo declarado do autor como pressuposto influente na escrita dos romances, percebe-se como ele usa a Bíblia e carnavalizando-a desloca as afirmações do sentido tradicional operando uma verdadeira construção teológica desconstrutiva. Seguindo este percurso, são destacados, especialmente nos romances chamados bíblicos, o conteúdo da teologia ficcional saramaguiana que, mesmo diferindo da reflexão teológica, relaciona-se com ela, na medida em que, revê questões que a interessam. / [en] The objective of this present work is to evidence, especially in the novels The Gospel According to Jesus Christ and Cain, what can be classified as the fictional theology of José Saramago, and how this is connected to the themes of theological reflection. To begin, it is necessary to follow the route that enables us to positively identify literature as an authentic theological expression, even in a non-theoretical format. In this way, the relationship between these two forms of historical scholarship , both in rapprochement and detachment, is discussed. However, there is a need to narrow the discussion to fictional novels in order to demonstrate its theological potential. With this backdrop, we penetrate the universe of Saramago seeking to unravel how its construction takes place. Having the author s declared atheism as a presumed influence in the writing of the novels, one perceives how he uses the Bible and carnivalizes it to replace the claims of its traditional meaning by using a true deconstructive theological construction. Continuing in this same direction, the content of the fictional theology of Saramago is highlighted, especially in the so-called biblical novels that, despite their differentiation from theological reflection, are actually related to it insofar as they retrace questions that are of interest to it.

Francis Picabia, peintre-poète qui a traversé toute la première moitié du XXe siècle, nous a laissé en héritage un riche corpus d’écrits, dont la plupart a été publié, mais il reste encore aujourd’hui de nombreux inédits et des avant-textes conservés dans les archives. Si la période Dada de la poésie de Picabia est peut-être la plus connue, l’artiste a continué d’écrire des poèmes toute sa vie (il est disparu en 1953). C’est notamment après la rencontre avec son dernier éditeur, Pierre André Benoit (PAB), en 1948, que Picabia décide de révéler encore une fois saveine poétique, et publie un grand nombre de recueils, écrits entre 1939 et 1951.Ces poèmes naissent, plus particulièrement, sous l’empreinte des lectures des oeuvres de Friedrich Nietzsche, car l’artiste reprend systématiquement des passages du Gai Savoir, qui nous obligent à repenser les limites de l’écriture poétique, en général. On découvre alors une nouvelle manière de faire de la poésie, qui reprend, d’unemanière assez libre, le langage philosophique de La Gaya Scienza. PAB a sûrement compris la portée des nouveaux poèmes de Picabia et il s’est dédié à la réalisation de solutions créatives pour la présentation de ces écrits poétiques. Au-delà de cet intense travail il y a bien sûr une amitié, qui s’est manifestée notamment à traversl’échange de lettres, car les occasions de se rencontrer ont été très rares.Cette dernière période de l’écriture de Picabia est alors digne d’être remarquée et mérite d’être comprise et mise en valeur. Nous avons essayé, par cette recherche, de trouver une solution pour classer ces écrits, que nous aimerions inscrire dans le contexte de la « récriture intertextuelle ». / Francis Picabia (1879 – 1953), well-known French painter of the beginning of the twentieth century, was also an experimentalist poet of the avant-garde milieu, who wrote throughout his entire life. Part of his writings have been edited, but many unpublished works can still be found in archives. The Dada period of his poetry is perhaps best known, more particularly for his drawing-poems, but I have discovered during my research that his late writings contain many unrevealed aspects. Particularly after he met the editor Pierre André Benoit (PAB) in 1948, a new important period began in Picabia’s poetic output, during which he published his writings from 1939 to 1951. This intense collaboration took place mainly at a distance, through the exchange of frequent letters, soon turning into a sincere friendship. These publications, most of which are one-of-a-kind books, are printed personally by PAB on his printing press, and are often illustrated by the artist or by the editor himself.Surprisingly, Picabia’s late poetry is strongly marked by Friedrich Nietzsche’s writings, in particular by The Gay Science (1882). The “borrowings” are so evident, that they call for a specific, new interpretation: thus, this peculiar creative process can be seen as a phenomenon of appropriation, or “intertextual rewriting”. This process of “copying”, was applied by the artist indistinctively to his art and poetry and can function as a possible solutionfor the classification of his controversial poems.
