Memória e experiência no cinema de Wim Wenders - evidências de um diálogo com a filosofia de Walter Benjamin : cenas para uma educação dos sentidos

Esta dissertação apresenta o resultado de uma pesquisa, de cunho teórico, cujo escopo é apreender, na obra fílmica de Wim Wenders, o percurso estético narrativo que esse cineasta faz, tendo como eixo central de discussão o conceito de memória e experiência. As perguntas que norteiam a pesquisa são: de que forma a estética fílmica dos filmes de Wenders elabora a memória e como esta está vinculada à ideia de experiência? De que forma o fazer fílmico desse cineasta pode ser uma referência e estímulo para o âmbito da educação, em especial para a formação dos sentidos? A pesquisa propõe uma tríade dialógica entre cinema, filosofia e educação. Para tanto, traça um panorama sobre a estética de alguns filmes de Wenders em diálogo com a filosofia ensaística de Walter Benjamin. O principal objeto de análise é o filme Alice nas cidades (WENDERS, 1973). Com isso, pretende-se estabelecer um diálogo e traçar um paralelo (relação) entre os conceitos de experiência e memória, presentes na estética fílmica de Wenders, e o conceito de memória e experiência tal como apresentada em alguns ensaios benjaminianos. A hipótese principal considera que a memória coletiva e a experiência fazem par e caminham com a história da educação, e são elementos fundamentais para a formação dos sentidos. A compreensão desses dois conceitos, a partir de uma perspectiva crítica, pode ensejar uma experiência e formação estética que produzem as condições de possibilidade para a contraposição à barbárie que conduz à pobreza da experiência, também entendida como regressão dos sentidos. A segunda hipótese é de que o conceito de memória e experiência no cinema de Wim Wenders expressa uma estética comprometida na construção de uma expressão artística que dirige a atenção à ressurgência do passado no presente, isto é, evidências da experiência e da memória na linguagem cinematográfica. O esforço da pesquisa pode ser resumido na tentativa de um exercício de análise e discussão teórica em torno da relação entre educação e cinema. Para tanto, apontam-se, por meio da obra cinematográfica de Wenders, evidências de aproximação com o pensamento de Benjamin, em especial com relação aos conceitos de memória e experiência, tal como se apresenta no percurso criativo do cineasta. Tais conceitos contribuem, por meio da obra de Wenders, em diálogo com a filosofia de Benjamin, para produzirem um contraponto à educação estética na formação do professor.

A brief survey on online analysis of movement data

The increasing availability of mobility data and the awareness of its importance and value have been motivating many researchers to the development of models and tools for analyzing movement data. This paper presents a brief survey of significant research works about modeling, processing and visualization of data about moving objects. We identified some key research fields that will provide better features for online analysis of movement data. As result of the literature review, we suggest a generic multi-layer architecture for the development of an online analysis processing software tool, which will be used for the definition of the future work of our team.

Accountability and co-production of information and control: social observatories and their relationship with government agencies

Abstract:Through the development of a proposal to categorize accountability into four stages - classical, cross-sectional, systemic, and diffused -, this article aims to identify characteristics of co-production of information and socio-political control of public administration in the work of Brazilian social observatories in relationship with government control agencies. The study analyses data from 20 social observatories and, particularly, three experiences of co-production of information and control, based on a systemic perspective on accountability and a model with four categories: Political and cultural; valuing; systemic-organizational, and production. The conclusions summarize characteristics of these practices, specific phases in the accountability processes, as well as the potentialities and challenges of co-production of information and control, which not only influences, but it is also influenced by the accountability system.

On the Suitability of Suffix Arrays for Lempel-Ziv Data Compression

Lossless compression algorithms of the Lempel-Ziv (LZ) family are widely used nowadays. Regarding time and memory requirements, LZ encoding is much more demanding than decoding. In order to speed up the encoding process, efficient data structures, like suffix trees, have been used. In this paper, we explore the use of suffix arrays to hold the dictionary of the LZ encoder, and propose an algorithm to search over it. We show that the resulting encoder attains roughly the same compression ratios as those based on suffix trees. However, the amount of memory required by the suffix array is fixed, and much lower than the variable amount of memory used by encoders based on suffix trees (which depends on the text to encode). We conclude that suffix arrays, when compared to suffix trees in terms of the trade-off among time, memory, and compression ratio, may be preferable in scenarios (e.g., embedded systems) where memory is at a premium and high speed is not critical.

A Tradução reinventada em The Invention of Solitude de Paul Auster

A leitura da obra de Paul Auster, desde os primeiros poemas e ensaios até à mais recente ficção, revela uma constante reflexão metalinguística e metaficcional sobre o trabalho da escrita. Auster equaciona o problema da escrita enquanto acto, permitindo ao leitor acompanhar e participar desse processo de construção. A narrativa e a linguagem intelectualizam-se, tornam-se conscientes, o que possibilita uma aproximação privilegiada ao ensino da tradução de textos literários através da própria literatura. The Invention of Solitude é como uma arte poética inspirada na experiência efectiva do sujeito, enquanto escritor e tradutor. Podemos considerá-lo um romance-manifesto em duas partes (Portrait of an Invisible Man e The Book of Memory), com especial incidência na exploração analítica da cena da escrita, utilizando a personagem-escritor e suas vivências como cobaia neste processo de auto e heteroconhecimento. A partir da análise aplicada de The Invention of Solitude, este artigo irá remeter também para os ensaios de Ernest Gellner sobre Wittgenstein em Language and Solitude, entre outros escritores que se debruçaram igualmente sobre questões ligadas à tradução literária, como Dryden, Goethe, Nietzsche, Benjamin, Ortega y Gasset e Octávio Paz.

Paul Auster and the music of change: building new stories

In the work of Paul Auster (Newark, 1947 - ), we find two main themes: the sense of loss and existential drift and the loneliness of the individual fully committed to the work of writing, as if he had been confined to the book that commands his life. However, this second theme is clearly the dominant one because the character's space of solitude may include its own wandering, because this wandering is also often performed inside the four walls of a room, just like it is narrated inside the space of the page and the book. Both in his poetry, essays and fiction, Auster seems to face the work of writing as an actual physical effort of effective construction, as if the words that are aligned in the poem-text were stones to place in a row when building a wall or some other structure in stone.

The Greatest lover: a post-colonial rewriting of My Fair Lady

INTRODUCTION The popular Hong Kong comedy, The Greatest Lover, re-incarnates one of the most popular western musicals, My Fair Lady. OBJECTIVES 1. To find out in what major ways My Fair Lady was rewritten as the Hong Kong Cantonese movie, Gungzi Docing (The Greatest Lover). 2. To find out the socio-political, socio-linguistic, and gender ideology behind the rewriting. METHODOLOGY 1. To note the similarity of the themes for both works – a creator falling in love with his/her creation, and class prejudice and cross-class romance. 2. To note how the times of The Greatest Lover differ from that of My Fair Lady. 3. To note how the main characters in The Greatest Lover differ from My Fair Lady in terms of profession, gender, etc. 4. To note how the plot of The Greatest Lover differs from that of My Fair Lady. 5. To note how focus on language in The Greatest Lover compares with that in My Fair Lady. 6. To discuss the ideological implications of the differences noted above, e.g. women in Hong Kong today have much higher status than women in Victorian England; the conflict between local Hong Kong people and both legal and illegal immigrants from Mainland China is even more serious than that between the British upper middle class and the lower class during the Victorian period. 7. Andre Lefevere (1992) argues that translation and adaptation are rewriting informed and influenced by the rewriter’s ideology, among other things. 8. Both Aline Remael (1995) and Patrick Cattrysse (1992) think that film adaptation is a kind of translation. 9. Sirkkus Aaltonen (2000) argues that drama translation mirrors the ideologies of the target society. CONCLUSION 1. The Greatest Lover projects local cultural significance onto My Fair Lady by helping us to appreciate an important Western work of art through the Hong Kong Cantonese perspective. 2. Broader issues in translation and intercultural studies are also considered.

Towards a complex model of cooperative learning

Este artigo é uma introdução à teoria do paradigma desconstrutivo de aprendizagem cooperativa. Centenas de estudos provam com evidências o facto de que as estruturas e os processos de aprendizagem cooperativa aumentam o desempenho académico, reforçam as competências de aprendizagem ao longo da vida e desenvolvem competências sociais, pessoais de cada aluno de uma forma mais eficaz e usta, comparativamente às estruturas tradicionais de aprendizagem nas escolas. Enfrentando os desafios dos nossos sistemas educativos, seria interessante elaborar o quadro teórico do discurso da aprendizagem cooperativa, dos últimos 40 anos, a partir de um aspeto prático dentro do contexto teórico e metodológico. Nas últimas décadas, o discurso cooperativo elaborou os elementos práticos e teóricos de estruturas e processos de aprendizagem cooperativa. Gostaríamos de fazer um resumo desses elementos com o objetivo de compreender que tipo de mudanças estruturais podem fazer diferenças reais na prática de ensino e aprendizagem. Os princípios básicos de estruturas cooperativas, os papéis de cooperação e as atitudes cooperativas são os principais elementos que podemos brevemente descrever aqui, de modo a criar um quadro para a compreensão teórica e prática de como podemos sugerir os elementos de aprendizagem cooperativa na nossa prática em sala de aula. Na minha perspetiva, esta complexa teoria da aprendizagem cooperativa pode ser entendida como um paradigma desconstrutivo que fornece algumas respostas pragmáticas para as questões da nossa prática educativa quotidiana, a partir do nível da sala de aula para o nível de sistema educativo, com foco na destruição de estruturas hierárquicas e antidemocráticas de aprendizagem e, criando, ao mesmo tempo, as estruturas cooperativas.

Travelling to India: Eliza Fay’s narrative account of her voyages

Eliza Fay’s Original Letters from India (1817), initially sold to the Calcutta Gazette to pay off her debts, aroused the curiosity and interest of Edward M. Forster, while he was doing research for his best-selling novel, A Passage to India. In his own words, “Eliza Fay is a work of art.” (apud Fay 7) The value of E. Fay’s travelogue, comprising not one, but three voyages to India (in 1779, 1784, 1796) can be easily explained if we take into account the scope of its geographical coverage, the hardships of its historical context (the political chaos brought about by the fall of the Mughal empire and the consolidation of the British rule in the Indian subcontinent) and the heroism of the first person-narrator that emerges behind the descriptive sketches and the scenes of adversity and imminent danger. Thus the current analysis will focus on the E. Fay’s adventurous mode of narrating, e.g., the discursive situatedness of the traveller visà- vis the Other(s) (European and non-European peoples and loci) and the constraints imposed by the patriarchal idealization of the domestic Woman and their alleged feebleness.

Specification of software architecture reconfiguration

In the past years, Software Architecture has attracted increased attention by academia and industry as the unifying concept to structure the design of complex systems. One particular research area deals with the possibility of reconfiguring architectures to adapt the systems they describe to new requirements. Reconfiguration amounts to adding and removing components and connections, and may have to occur without stopping the execution of the system being reconfigured. This work contributes to the formal description of such a process. Taking as a premise that a single formalism hardly ever satisfies all requirements in every situation, we present three approaches, each one with its own assumptions about the systems it can be applied to and with different advantages and disadvantages. Each approach is based on work of other researchers and has the aesthetic concern of changing as little as possible the original formalism, keeping its spirit. The first approach shows how a given reconfiguration can be specified in the same manner as the system it is applied to and in a way to be efficiently executed. The second approach explores the Chemical Abstract Machine, a formalism for rewriting multisets of terms, to describe architectures, computations, and reconfigurations in a uniform way. The last approach uses a UNITY-like parallel programming design language to describe computations, represents architectures by diagrams in the sense of Category Theory, and specifies reconfigurations by graph transformation rules.

Effect of technical parameters on dose and image quality in a computed radiography system

The discovery of X-rays was undoubtedly one of the greatest stimulus for improving the efficiency in the provision of healthcare services. The ability to view, non-invasively, inside the human body has greatly facilitated the work of professionals in diagnosis of diseases. The exclusive focus on image quality (IQ), without understanding how they are obtained, affect negatively the efficiency in diagnostic radiology. The equilibrium between the benefits and the risks are often forgotten. It is necessary to adopt optimization strategies to maximize the benefits (image quality) and minimize risk (dose to the patient) in radiological facilities. In radiology, the implementation of optimization strategies involves an understanding of images acquisition process. When a radiographer adopts a certain value of a parameter (tube potential [kVp], tube current-exposure time product [mAs] or additional filtration), it is essential to know its meaning and impact of their variation in dose and image quality. Without this, any optimization strategy will be a failure. Worldwide, data show that use of x-rays has been increasingly frequent. In Cabo Verde, we note an effort by healthcare institutions (e.g. Ministry of Health) in equipping radiological facilities and the recent installation of a telemedicine system requires purchase of new radiological equipment. In addition, the transition from screen-films to digital systems is characterized by a raise in patient exposure. Given that this transition is slower in less developed countries, as is the case of Cabo Verde, the need to adopt optimization strategies becomes increasingly necessary. This study was conducted as an attempt to answer that need. Although this work is about objective evaluation of image quality, and in medical practice the evaluation is usually subjective (visual evaluation of images by radiographer / radiologist), studies reported a correlation between these two types of evaluation (objective and subjective) [5-7] which accredits for conducting such studies. The purpose of this study is to evaluate the effect of exposure parameters (kVp and mAs) when using additional Cooper (Cu) filtration in dose and image quality in a Computed Radiography system.

Improvement of a filters method in a derivative free optimization

Constraints nonlinear optimization problems can be solved using penalty or barrier functions. This strategy, based on solving the problems without constraints obtained from the original problem, have shown to be e ective, particularly when used with direct search methods. An alternative to solve the previous problems is the lters method. The lters method introduced by Fletcher and Ley er in 2002, , has been widely used to solve problems of the type mentioned above. These methods use a strategy di erent from the barrier or penalty functions. The previous functions de ne a new one that combine the objective function and the constraints, while the lters method treat optimization problems as a bi-objective problems that minimize the objective function and a function that aggregates the constraints. Motivated by the work of Audet and Dennis in 2004, using lters method with derivative-free algorithms, the authors developed works where other direct search meth- ods were used, combining their potential with the lters method. More recently. In a new variant of these methods was presented, where it some alternative aggregation restrictions for the construction of lters were proposed. This paper presents a variant of the lters method, more robust than the previous ones, that has been implemented with a safeguard procedure where values of the function and constraints are interlinked and not treated completely independently.
