Literatura boa é que eu gosto; ruim a que eu não gosto: fóruns de discussão literária da rede social ORKUT e a Teoria da Valoração uma análise crítica

Esta dissertação se insere nos estudos de Linguística e é vinculada à Análise Crítica do Discurso (FAIRCLOUGH, 1989, 2003) e à Linguística Sistêmico-Funcional (HALLIDAY, 1970, 1973), investigando o que é a qualidade literária para os internautas que interagem em fóruns de discussão do Orkut, à luz da Teoria da Valoração (MARTIN ; WHITE, 2005). De acordo com as categorias que abrangem o subsistema da Atitude da Teoria da Valoração (MARTIN ; WHITE, 2005), analisa-se como os leitores internautas se posicionam sobre a questão da qualidade literária e a ideologia que perpassa seus discursos. O conceito de ideologia adotado é o proposto por Thompson (2009), para quem o conceito deve ser compreendido a partir da noção de hegemonia e poder, ou seja, a ideologia necessariamente estabelece e sustenta relações de dominação, reproduzindo a ordem social que favorece indivíduos e grupos dominantes.O corpus desta pesquisa é composto de três amostras colhidas entre 15/07/2009 e 05/01/2010 correspondentes a uma discussão iniciada em comunidade relacionada a assuntos literários. A AMOSTRA 1 refere-se ao tópico Leitura difícil é sinal de qualidade?, da comunidade Literatura; a AMOSTRA 2, se refere ao tópico Qualidade do texto literário, da comunidade Discutindo... literatura e, por fim, a AMOSTRA 3 representa o tópico O que é um bom texto literário para você, também da comunidade Literatura. Cada discussão possui congruências e divergências quanto às representações sobre literatura e essas foram também analisadas. Não obstante, o que nos interessa é perceber como as ideologias perpassam seus discursos de acordo com os valores que os internautas atribuem a aspectos do texto literário. Foram escolhidos fóruns de discussão online do Orkut porque as interações em redes sociais constituem elemento novo das práticas sociais e, portanto, relevantes pontos de apoio para a investigação da criação de sentidos sobre o conceito de boa literatura. Investigar como a literatura, objeto de estudo acadêmico, é analisada em tais espaços cibernéticos é instigante, por não ser usual. Os resultados obtidos nessa pesquisa sugerem que o internauta reproduz o discurso acadêmico hegemônico acerca da qualidade literária ao debater a qualidade intrínseca do texto literário com a ressalva de manifestar seu contentamento ou descontentamento acerca de determinados textos literários e escritores, dado novo que revela uma característica deste espaço não institucional de discussão, em que os internautas se sentem à vontade para manifestar sua opinião

Era uma vez... contos, romances, poemas: um tesouro linguístico

Esta dissertação tem por objetivo promover a exploração do texto literário como meio de aquisição/desenvolvimento do domínio linguístico e apresentar uma perspectiva de aprendizagem de língua e literatura como processo indissociável, que se realiza na interação dos sujeitos com diferentes textos. Trabalha-se no limite entre gramática, linguística e literatura cujo objeto é a palavra, tendo como propósito o ensino da Língua Portuguesa. Objetiva-se, ainda, promover uma reflexão que possa melhorar as práticas quotidianas do ensino da língua e fornecer subsídios teóricos e práticos aos professores de Língua Portuguesa e Literatura visando a ampliar opções para o preparo e realização de aulas de leitura e escrita. O aluno, por sua vez, é convidado a interagir com o material apresentado de forma criativa, desenvolvendo sua habilidade de pesquisa em diferentes fontes e sua capacidade de relacionar saberes oriundos de diferentes áreas do conhecimento, respondendo positivamente a propostas desafiadoras de interpretação da realidade que o circunda e da história da sua sociedade, a partir de uma abordagem significativa. Faz-se um conjunto de reflexões acerca da língua, da leitura e da literatura enfatizando que o ensino da língua deve ser pautado no texto, na sua interpretação, estrutura e significação, desenvolvendo a percepção dos elementos que constituem a linguagem, para habituar o aluno a ver as palavras em sua pluralidade de sons, imagens e sentidos. No centro deste trabalho, apresentam-se elementos que têm origem no exercício de práticas de orientação de ensino de língua e de literatura, buscando estratégias para minimizar as deficiências na competência de leitura e interpretação comprovadas pelas avaliações por que têm passado as escolas brasileiras. Finalizando tenta-se deixar claro que a meta desta dissertação é contribuir para que o ensino da língua e literatura promova de fato o desenvolvimento da linguagem em suas funções de compreensão, expressão e comunicação e em seus valores estéticos, formadores e informadores

// Afeto e derivações

Escrever como obra. Essa é a proposta de //. Produzir uma publicação que não separe o texto da plasticidade tendo como tema o afeto- sua produção, permanência e evanescência. Neste livro-objeto, pensar a escrita como arte [um fazer] e a escrita na arte [um localizar] é um mesmo movimento, um mesmo exercício. // incide sobre o campo do afeto como tema e da escrita como forma, partindo de trabalhos que problematizem o campo afetivo e/ou existam no contato escrita-arte. Nos vastos estudos que localizam o afeto como força central na constituição da paisagem urbana e das relações sociais, políticas e econômicas, busquei me movimentar por um espaço que tratasse das novas modalidades de um afeto íntimo e de uma intimidade pública. O cruzamento da pesquisa teórica com a produção de artistas contemporâneos apareceu como método de pesquisa e impulso produtivo apontando para um trabalho prático-teórico que trouxesse tanto uma escrita de si quanto uma escrita conceitual para dentro do trabalho. Em // a produção de um texto/obra parte da investigação sobre os modos de aparição de subjetividade e afetividade no contemporâneo, sobre como ressonâncias psicológicas e afetivas dão origem a uma escrita de superfícies estéticas, matérias visuais e operações gráficas

A crítica ensaística de Osman Lins sobre o acesso do jovem escolar à cultura brasileira

This text aims to address the critical essays of Osman Lins on the corpus of his works, reading and study, which consists of Portuguese textbooks adopted in schools for the teaching of the national language in the Secondary Course. More specifically, we intend to reflect on how Osman Lins analyzes the procedures adopted by the authors of these textbooks to introduce learners into Brazilian literature. Our object of study and analysis is restricted to six trials Lins published originally in 1965, the newspaper of Pernambuco University Press and later, in 1977, were collected in the form of the first chapter, titled "The Book didactic - First time: 1965 " (1977, p.13-40), the book From the Dream and Glory: Brazilian uncultural problems.

Ambivalencias y límites de la literatura como objeto para el estructuralismo

Nos proponemos esbozar una cierta trayectoria del paradigma estructuralista en el interior de la crítica literaria a partir de los distintos avatares a que fue sometido su objeto, la literatura. El estructuralismo basó su productividad en la irreductibilidad de las dicotomías que propuso, tales como langue / parole. La literatura, sin embargo, ofreció severas resistencias ante una reducción de su multiplicidad a semejantes categorías. El rigor de los análisis estructuralistas frente a tales resistencias no solo servirá para deslindar los límites del método, sino que contribuirá también a establecer todo un nuevo cuerpo de problemas para la crítica literaria contemporánea.

When the object speaks, a postcolonial encounter : anthropological, representations and Aboriginal's women's self-presentations

As an Aboriginal woman currently reviewing feminist literature in Australia, I have found that representations of Aboriginal women's gender have been generated predominantly by women anthropologists. Australian feminists utilise this literature in their writing and teaching and accept its truths without question; the most often quoted ethnographic text is Diane Bell's Daughters of the Dreaming (1983a).1 Feminists' lack of critical engagement with this literature implies that they are content to accept women anthropologists' representations because Aboriginal women are not central to their constructions of feminism.2 Instead the Aboriginal woman is positioned on the margins, a symbol of difference; a reminder that it is feminists who are the bearers of true womanhood.

Integrated health prediction of bridge systems using dynamic object oriented Bayesian networks (DOOBNS)

The serviceability and safety of bridges are crucial to people’s daily lives and to the national economy. Every effort should be taken to make sure that bridges function safely and properly as any damage or fault during the service life can lead to transport paralysis, catastrophic loss of property or even casualties. Nonetheless, aggressive environmental conditions, ever-increasing and changing traffic loads and aging can all contribute to bridge deterioration. With often constrained budget, it is of significance to identify bridges and bridge elements that should be given higher priority for maintenance, rehabilitation or replacement, and to select optimal strategy. Bridge health prediction is an essential underpinning science to bridge maintenance optimization, since the effectiveness of optimal maintenance decision is largely dependent on the forecasting accuracy of bridge health performance. The current approaches for bridge health prediction can be categorised into two groups: condition ratings based and structural reliability based. A comprehensive literature review has revealed the following limitations of the current modelling approaches: (1) it is not evident in literature to date that any integrated approaches exist for modelling both serviceability and safety aspects so that both performance criteria can be evaluated coherently; (2) complex system modelling approaches have not been successfully applied to bridge deterioration modelling though a bridge is a complex system composed of many inter-related bridge elements; (3) multiple bridge deterioration factors, such as deterioration dependencies among different bridge elements, observed information, maintenance actions and environmental effects have not been considered jointly; (4) the existing approaches are lacking in Bayesian updating ability to incorporate a variety of event information; (5) the assumption of series and/or parallel relationship for bridge level reliability is always held in all structural reliability estimation of bridge systems. To address the deficiencies listed above, this research proposes three novel models based on the Dynamic Object Oriented Bayesian Networks (DOOBNs) approach. Model I aims to address bridge deterioration in serviceability using condition ratings as the health index. The bridge deterioration is represented in a hierarchical relationship, in accordance with the physical structure, so that the contribution of each bridge element to bridge deterioration can be tracked. A discrete-time Markov process is employed to model deterioration of bridge elements over time. In Model II, bridge deterioration in terms of safety is addressed. The structural reliability of bridge systems is estimated from bridge elements to the entire bridge. By means of conditional probability tables (CPTs), not only series-parallel relationship but also complex probabilistic relationship in bridge systems can be effectively modelled. The structural reliability of each bridge element is evaluated from its limit state functions, considering the probability distributions of resistance and applied load. Both Models I and II are designed in three steps: modelling consideration, DOOBN development and parameters estimation. Model III integrates Models I and II to address bridge health performance in both serviceability and safety aspects jointly. The modelling of bridge ratings is modified so that every basic modelling unit denotes one physical bridge element. According to the specific materials used, the integration of condition ratings and structural reliability is implemented through critical failure modes. Three case studies have been conducted to validate the proposed models, respectively. Carefully selected data and knowledge from bridge experts, the National Bridge Inventory (NBI) and existing literature were utilised for model validation. In addition, event information was generated using simulation to demonstrate the Bayesian updating ability of the proposed models. The prediction results of condition ratings and structural reliability were presented and interpreted for basic bridge elements and the whole bridge system. The results obtained from Model II were compared with the ones obtained from traditional structural reliability methods. Overall, the prediction results demonstrate the feasibility of the proposed modelling approach for bridge health prediction and underpin the assertion that the three models can be used separately or integrated and are more effective than the current bridge deterioration modelling approaches. The primary contribution of this work is to enhance the knowledge in the field of bridge health prediction, where more comprehensive health performance in both serviceability and safety aspects are addressed jointly. The proposed models, characterised by probabilistic representation of bridge deterioration in hierarchical ways, demonstrated the effectiveness and pledge of DOOBNs approach to bridge health management. Additionally, the proposed models have significant potential for bridge maintenance optimization. Working together with advanced monitoring and inspection techniques, and a comprehensive bridge inventory, the proposed models can be used by bridge practitioners to achieve increased serviceability and safety as well as maintenance cost effectiveness.

Moving object detection in aerial video based on spatiotemporal saliency

In this paper, the problem of moving object detection in aerial video is addressed. While motion cues have been extensively exploited in the literature, how to use spatial information is still an open problem. To deal with this issue, we propose a novel hierarchical moving target detection method based on spatiotemporal saliency. Temporal saliency is used to get a coarse segmentation, and spatial saliency is extracted to obtain the object’s appearance details in candidate motion regions. Finally, by combining temporal and spatial saliency information, we can get refined detection results. Additionally, in order to give a full description of the object distribution, spatial saliency is detected in both pixel and region levels based on local contrast. Experiments conducted on the VIVID dataset show that the proposed method is efficient and accurate.

Double-Edged Imitation : Theories and Practices of Pastiche in Literature

This study concentrates on the contested concept of pastiche in literary studies. It offers the first detailed examination of the history of the concept from its origins in the seventeenth century to the present, showing how pastiche emerged as a critical concept in interaction with the emerging conception of authorial originality and the copyright laws protecting it. One of the key results of this investigation is the contextualisation of the postmodern debate on pastiche. Even though postmodern critics often emphasise the radical novelty of pastiche, they in fact resuscitate older positions and arguments without necessarily reflecting on their historical conditions. This historical background is then used to analyse the distinction between the primarily French conception of pastiche as the imitation of style and the postmodern notion of it as the compilation of different elements. The latter s vagueness and inclusiveness detracts from its value as a critical concept. The study thus concentrates on the notion of stylistic pastiche, challenging the widespread prejudice that it is merely an indication of lack of talent. Because it is multiply based on repetition, pastiche is in fact a highly ambiguous or double-edged practice that calls into question the distinction between repetition and original, thereby undermining the received notion of individual unique authorship as a fundamental aesthetic value. Pastiche does not, however, constitute a radical upheaval of the basic assumptions on which the present institution of literature relies, since, in order to mark its difference, pastiche always refers to a source outside itself against which its difference is measured. Finally, the theoretical analysis of pastiche is applied to literary works. The pastiches written by Marcel Proust demonstrate how it can become an integral part of a writer s poetics: imitation of style is shown to provide Proust with a way of exploring the role of style as a connecting point between inner vision and reality. The pastiches of the Sherlock Holmes stories by Michael Dibdin, Nicholas Meyer and the duo Adrian Conan Doyle and John Dickson Carr illustrate the functions of pastiche within a genre detective fiction that is itself fundamentally repetitive. A.S. Byatt s Possession and D.M. Thomas s Charlotte use Victorian pastiches to investigate the conditions of literary creation in the age of postmodern suspicion of creativity and individuality. The study thus argues that the concept of pastiche has valuable insights to offer to literary criticism and theory, and that literary pastiches, though often dismissed in reviews and criticism, are a particularly interesting object of study precisely because of their characteristic ambiguity.

VISUAL OBJECT TRACKING VIA RANDOM FERNS BASED CLASSIFICATION

Designing a robust algorithm for visual object tracking has been a challenging task since many years. There are trackers in the literature that are reasonably accurate for many tracking scenarios but most of them are computationally expensive. This narrows down their applicability as many tracking applications demand real time response. In this paper, we present a tracker based on random ferns. Tracking is posed as a classification problem and classification is done using ferns. We used ferns as they rely on binary features and are extremely fast at both training and classification as compared to other classification algorithms. Our experiments show that the proposed tracker performs well on some of the most challenging tracking datasets and executes much faster than one of the state-of-the-art trackers, without much difference in tracking accuracy.

Foreground Object Segmentation from Binocular Stereo Video

Moving cameras are needed for a wide range of applications in robotics, vehicle systems, surveillance, etc. However, many foreground object segmentation methods reported in the literature are unsuitable for such settings; these methods assume that the camera is fixed and the background changes slowly, and are inadequate for segmenting objects in video if there is significant motion of the camera or background. To address this shortcoming, a new method for segmenting foreground objects is proposed that utilizes binocular video. The method is demonstrated in the application of tracking and segmenting people in video who are approximately facing the binocular camera rig. Given a stereo image pair, the system first tries to find faces. Starting at each face, the region containing the person is grown by merging regions from an over-segmented color image. The disparity map is used to guide this merging process. The system has been implemented on a consumer-grade PC, and tested on video sequences of people indoors obtained from a moving camera rig. As can be expected, the proposed method works well in situations where other foreground-background segmentation methods typically fail. We believe that this superior performance is partly due to the use of object detection to guide region merging in disparity/color foreground segmentation, and partly due to the use of disparity information available with a binocular rig, in contrast with most previous methods that assumed monocular sequences.

Telling stories of culture through literature

Grounded on Raymond Williams‘s definition of knowable community as a cultural tool to analyse literary texts, the essay reads the texts D.H.Lawrence wrote while travelling in the Mediterranean (Twilight in Italy, Sea and Sardinia and Etruscan Places) as knowable communities, bringing to the discussion the wide importance of literature not only as an object for aesthetic or textual readings, but also as a signifying practice which tells stories of culture. Departing from some considerations regarding the historical development of the relationship between literature and culture, the essay analyses the ways D. H. Lawrence constructed maps of meaning, where the readers, in a dynamic relation with the texts, apprehend experiences, structures and feelings; putting into perspective Williams‘s theory of culture as a whole way of life, it also analyses the ways the author communicates and organizes these experiences, creating a space of communication and operating at different levels of reality: on the one hand, the reality of the whole way of Italian life, and, on the other hand, the reality of the reader who aspires to make sense and to create an interpretative context where all the information is put, and, also, the reality of the writer in the poetic act of writing. To read these travel writings as knowable communities is to understand them as a form that invents a community with no other existence but that of the literary text. The cultural construction we find in these texts is the result of the selection, and interpretation done by D.H.Lawrence, as well as the product of the author‘s enunciative positions, and of his epistemological and ontological filigrees of existence, structured by the conditions of possibility. In the rearticulation of the text, of the writer and of the reader, in a dynamic and shared process of discursive alliances, we understand that Lawrence tells stories of the Mediterranean through his literary art.
