ISTO NÃO É TV, É MTV: linguagem da MTV brasileira

A MTV brasileira está no ar há 15 anos no Brasil e desde o início de suas transmissões, em 1990, evoluiu consideravelmente a variedade de programas que oferece diariamente em sua grade de programação, saindo da simples reprodução de videoclipes. Essa variedade de programas, no entanto, é caracterizada por uma unidade discursiva que diferencia a MTV das outras emissoras de televisão aberta. Enquanto outras emissoras trabalham com gêneros diferentes de programas, em especial as que compõem a grade de programação de televisão aberta, a MTV consegue criar uma grade de programação diversificada, sempre direcionada a um público específico: o universo jovem. Objetivou-se realizar uma leitura qualitativa da linguagem do material simbólico que esta emissora produz a uma faixa de público especializada, subsidiada pela análise crítica de discurso, a semiótica e os estudos teóricos da Comunicação Social. Compõem o corpus de análise, os programas e vinhetas inéditos da semana de 23 a 29 de janeiro de 2006. Não foram consideradas as reprises. Demonstrou-se que é possível identificar uma estrutura discursiva que compõe uma linguagem, um discurso, que caracterizam a MTV e a diferenciam de outros canais de televisão aberta e a cabo. Uma linguagem que combina elementos do universo de sua principal audiência, os jovens. Palavras-chave: comunicação, MTV, análise de discurso, semiótica, jovem.

O EVANGELHO SEGUNDO DOSTOIÉVSKI UMA ABORDAGEM INTERTEXTUAL DA IMAGEM DE CRISTO NO ROMANCE O IDIOTA

No romance O Idiota, Dostoiévski cria, por meio do príncipe Míchkin, uma personagem com as características do Cristo. Sabe-se que a Bíblia, principalmente o Novo Testamento, acompanhou o escritor desde sua infância até o momento de sua morte. O primeiro capítulo, dedicado ao referencial teórico da pesquisa, lida com o universo da linguagem. Tanto o texto literário quanto a literatura bíblica procedem do mito. Neste sen-tido, religião e literatura se tocam e se aproximam. O segundo capítulo foi escrito na intenção de mostrar como o Cristo e os Evangelhos são temas, motivos e imagens recorrentes na obra de Dostoiévski. A literatura bíblica está presente, com mais ou menos intensidade, em diversas das principais obras do escritor russo e não somente em O Idiota. A hipótese de que Dostoiévski cria um Cristo e um Evangelho por meio de O Idiota é demonstrada na análise do romance, no terceiro capítulo. A tese proposta é: Dostoiévski desenvolve um evangelho literário, por meio de Míchkin, misto de um Cristo russo, ao mesmo tempo divino e humano, mas também idiota e quixotesco. Na dinâmica intertextual entre os Evangelhos bíblicos e O Idiota, entre Cristo e Míchkin, a literatura e o sagrado se revelam, como uma presença divina. Nas cenas e na estruturação do enredo que compõe o romance, Cristo se manifesta nas ações de Míchkin, na luz, na beleza, mas também na tragicidade de uma trajetória deslocada e antinômica. O amor e a compaixão ganham forma e vida na presen-ça do príncipe, vazio de si, servo de todos.

The use of site-directed fluorophore labeling and donor–donor energy migration to investigate solution structure and dynamics in proteins

The use of molecular genetics for introducing fluorescent molecules enables the use of donor–donor energy migration to determine intramolecular distances in a variety of proteins. This approach can be applied to examine the overall molecular dimensions of proteins and to investigate structural changes upon interactions with specific target molecules. In this report, the donor–donor energy migration method is demonstrated by experiments with the latent form of plasminogen activator inhibitor type 1. Based on the known x-ray structure of plasminogen activator inhibitor type 1, three positions forming the corners of a triangle were chosen. Double Cys substitution mutants (V106C-H185C, H185C-M266C, and M266C-V106C) and corresponding single substitution mutants (V106C, H185C, and M266C) were created and labeled with a sulfhydryl specific derivative of BODIPY (=the D molecule). The side lengths of this triangle were obtained from analyses of the experimental data. The analyses account for the local anisotropic order and rotational motions of the D molecules, as well as for the influence of a partial DD-labeling. The distances, as determined from x-ray diffraction, between the Cα-atoms of the positions V106C–H185C, H185C–M266C, and M266C–V106C were 60.9, 30.8, and 55.1 Å, respectively. These are in good agreement with the distances of 54 ± 4, 38 ± 3, and 55 ± 3 Å, as determined between the BODIPY groups attached via linkers to the same residues. Although the positions of the D-molecules and the Cα-atoms physically cannot coincide, there is a reasonable agreement between the methods.

Preassembly of interleukin 2 (IL-2) receptor subunits on resting Kit 225 K6 T cells and their modulation by IL-2, IL-7, and IL-15: A fluorescence resonance energy transfer study

Assembly and mutual proximities of α, β, and γc subunits of the interleukin 2 receptors (IL-2R) in plasma membranes of Kit 225 K6 T lymphoma cells were investigated by fluorescence resonance energy transfer (FRET) using fluorescein isothiocyanate- and Cy3-conjugated monoclonal antibodies (mAbs) that were directed against the IL-2Rα, IL-2Rβ, and γc subunits of IL-2R. The cell-surface distribution of subunits was analyzed at the nanometer scale (2–10 nm) by FRET on a cell-by-cell basis. The cells were probed in resting phase and after coculture with saturating concentrations of IL-2, IL-7, and IL-15. FRET data from donor- and acceptor-labeled IL-2Rβ-α, γ-α, and γ-β pairs demonstrated close proximity of all subunits to each other in the plasma membrane of resting T cells. These mutual proximities do not appear to represent mAb-induced microaggregation, because FRET measurements with Fab fragments of the mAbs gave similar results. The relative proximities were meaningfully modulated by binding of IL-2, IL-7, and IL-15. Based on FRET analysis the topology of the three subunits at the surface of resting cells can be best described by a “triangular model” in the absence of added interleukins. IL-2 strengthens the bridges between the subunits, making the triangle more compact. IL-7 and IL-15 act in the opposite direction by opening the triangle possibly because they associate their private specific α receptors with the β and/or γc subunits of the IL-2R complex. These data suggest that IL-2R subunits are already colocalized in resting T cells and do not require cytokine-induced redistribution. This colocalization is significantly modulated by binding of relevant interleukins in a cytokine-specific manner.

Faithful representation of similarities among three-dimensional shapes in human vision.

Efficient and reliable classification of visual stimuli requires that their representations reside a low-dimensional and, therefore, computationally manageable feature space. We investigated the ability of the human visual system to derive such representations from the sensory input-a highly nontrivial task, given the million or so dimensions of the visual signal at its entry point to the cortex. In a series of experiments, subjects were presented with sets of parametrically defined shapes; the points in the common high-dimensional parameter space corresponding to the individual shapes formed regular planar (two-dimensional) patterns such as a triangle, a square, etc. We then used multidimensional scaling to arrange the shapes in planar configurations, dictated by their experimentally determined perceived similarities. The resulting configurations closely resembled the original arrangements of the stimuli in the parameter space. This achievement of the human visual system was replicated by a computational model derived from a theory of object representation in the brain, according to which similarities between objects, and not the geometry of each object, need to be faithfully represented.

"Another Way": The Pneumatology of Deleuzean Minoritarian Communal Interpretation in Scripture, the 16th Century Radical Reformation, and Alternative 21st Century Anabaptist Community

This dissertation proposes a constructive theology of the Holy Spirit called the "pneumatology of minoritarian communal interpretation," the alternative creation of meaning within an oppressive majority context. It illustrates the convergence of Deleuzean philosophy with Anabaptist pneumatology and media communal interpretation theory in three particular locations: 1) selected mentions of the Holy Spirit in the Hebrew Bible and Christian New Testament; 2) the 16th century Radical Reformation; and 3) "Another Way," a 21st century alternative Anabaptist group focused around the spiritual discussion of art and popular media. Chapter One outlines the three theories. Chapter Two examines the Holy Spirit in the Hebrew Bible, particularly 1 Samuel 8, the book of Ezekiel, and the Gospel narratives. Chapter Three examines the pneumatological writings of the Radical Reformers, concentrating particularly on their theologies of the intersection between church and the surrounding majoritarian culture. Chapter Four outlines my original field research with Another Way, and examines the tension between minoritarian communal interpretation and the 21st century semiotic regime. Chapter Five then summarizes the conversations between theory and illustration to propose the pneumatology of minoritarian communal interpretation for Christian theology.

Astros no rock: uma perspectiva sociocultural no uso da canção na educação em ciências

A incorporação de elementos da cultura primeira do estudante no processo de ensino-aprendizagem foi defendida pelo pedagogo francês Georges Snyders (1988) em sua obra \"A Alegria na Escola\". Esta pesquisa contribuiu com essa interface, identificando, no discurso de canções do rock n\' roll, elementos textuais que possibilitem reflexões no âmbito conceitual, epistemológico e sociopolítico sobre a exploração do espaço. O objeto de estudo neste trabalho são canções do período entre as décadas de 1960 e 1970 que possuem representações sobre a astronomia e as missões espaciais. O uso do rock justificou-se pelo fato de temas sobre exploração espacial aparecerem no trabalho de diversos artistas desse gênero musical, permitindo reflexões em nível conceitual, epistemológico e sociopolítico sobre a ciência, a tecnologia e suas relações com a sociedade e o ambiente. Além disso, identificamos que tanto o rock quanto as missões espaciais foram fenômenos culturais que dependeram em sua gênese dos avanços da tecnologia e da ciência e tiveram sua repercussão na sociedade através de processos midiáticos. Essas canções foram selecionadas entre os diversos gêneros de rock, e analisadas a partir de referenciais semiodiscursivos. As atividades foram aplicadas em situações formais de ensino - ensino médio e ensino superior -, em formação continuada de professores e projetos de ensino não formal na escola. No processo de ensinoaprendizagem, foram desenvolvidas atividades que envolviam leitura-comentada da canção, identificando na letra, melodia e harmonia, aspectos que evidenciavam um discurso crítico sobre a ciência e sua relação com a sociedade e o ambiente. Essas atividades envolveram três instâncias: Elaboração, Aplicação e Análise. Como referencial norteador dessas etapas, nos valemos das teorias socioculturais de Vigotski (2001), Snyders (1988) e Freire (2013).

Gramática de la casa: perspectivas de análisis arqueológico de los espacios domésticos medievales en la Península Ibérica (siglos VII-XIII)

El espacio doméstico construido es un producto social que a su vez crea sociedad. La casa constituye un escenario privilegiado, un medio de expresión y transmisión de conductas y comportamientos. No obstante, resulta muy difícil comprender el espacio social a través de unas ruinas arqueológicas vacías y carentes de tercera dimensión, y se corre el riesgo de proyectar una imagen historiográfica previamente construida sobre las sociedades estudiadas. La comprensión del espacio social requiere formalizar y discutir los patrones formales de las estructuras domésticas y sus formas de agrupación. Este trabajo aborda el estudio de los espacios domésticos desde una perspectiva lingüística (una gramática de la casa), distinguiendo los elementos en sí y sus combinaciones. Se definen tres niveles distintos de análisis del hecho doméstico: el morfológico, que se ocupa de la forma de las unidades domésticas y de las transformaciones que experimentan; el sintáctico que enfatiza las relaciones entre las estructuras elementales en el marco de una estructura espacial organizada; y el semiótico, que las analiza como expresiones sociales, materialización e instrumento de significados culturales. De acuerdo a esta perspectiva se propone una reflexión metodológica sobre la caracterización de los espacios domésticos medievales e islámicos en la Península Ibérica; se plantean los problemas derivados del uso social del espacio, los modelos domésticos y su diacronía, y se discute acerca de la casa como indicador material de islamización.

La integració conceptual o blending i l’arc de Sant Martí: vers una semàntica cognitiva diacrònica i cultural

Aquest article fa un estudi onomasiològic de les denominacions de l’arc de Sant Martí en una perspectiva diacrònica, de contacte de llengües (català, occità, aragonès, etc.) i segons la teoria de la integració conceptual o blending. Planteja la necessitat que la semàntica diacrònica cognitiva faça pròpia l’orientació cultural (fonamentalment, antropològica, històrica social i cultural) i semiòtica.

El relato por otros medios: ¿un giro transmediático?

La reflexión en torno a las narraciones transmediáticas ha sido muy intensa en los últimos diez años. En este artículo intentamos desbrozar el concepto, dar cuenta de su especificidad y mostrar algunos ejemplos clásicos y otros más recientes. También apuntaremos algunas dificultades y retos que plantea a los estudios no sólo narratológicos, sino también en los márgenes entre estos y otros dominios tanto semióticos como de los Media Studies: las dimensiones y los límites de una “historia” de la narración transmedia, las explicaciones económicas de su pujanza actual, el afán de construcción de universos narrativos complejos y la inmersión en ellos de los fans, el papel crucial de la serialidad, la dimensión promocional y más en general paratextual de las narraciones trasmediáticas y finalmente la extensión del fenómeno más allá del dominio de la ficción. El “giro narrativo” descrito en las ciencias sociales y en muchos discursos públicos hace ya unas décadas debería complementarse ahora con un “giro transmediático”, funcional al primero y a la manera de su brazo secular (tecnológico y económico).

Neutrosophic and Modal Components of Relations in Complex Systems

Semiotic components in the relations of complex systems depend on the Subject. There are two main semiotic components: Neutrosophic and Modal. Modal components are alethical and deontical. In this paper the authors applied the theory of Neutrosophy and Modal Logic to Deontical Impure Systems.

International conference paper presentations: A multimodal analysis to determine effectiveness

International conference presentations represent one of the biggest challenges for academics using English as a Lingua Franca (ELF). This paper aims to initiate exploration into the multimodal academic discourse of oral presentations, including the verbal, written, non-verbal material (NVM) and body language modes. It offers a Systemic Functional Linguistic (SFL) and multimodal framework of presentations to enhance mixed-disciplinary ELF academics' awareness of what needs to be taken into account to communicate effectively at conferences. The model is also used to establish evaluation criteria for the presenters' talks and to carry out a multimodal discourse analysis of four well-rated 20-min talks, two from the technical sciences and two from the social sciences in a workshop scenario. The findings from the analysis and interviews indicate that: (a) a greater awareness of the mode affordances and their combinations can lead to improved performances; (b) higher reliance on the visual modes can compensate for verbal deficiencies; and (c) effective speakers tend to use a variety of modes that often overlap but work together to convey specific meanings. However, firm conclusions cannot be drawn on the basis of workshop presentations, and further studies on the multimodal analysis of ‘real conferences’ within specific disciplines are encouraged.

Behaviours, Processes and Probabilistic Environmental Functions in H-Open Systems

The Patten’s Theory of the Environment, supposes an impotent contribution to the Theoretical Ecology. The hypothesis of the duality of environments, the creaon and genon functions and the three developed propositions are so much of great importance in the field of the Applied Mathematical as Ecology. The authors have undertaken an amplification and revision of this theory, developing the following steps: 1) A theory of processes. 2) A definition of structural and behavioural functions. 3) A probabilistic definition of the environmental functions. In this paper the authors develop the theory of behavioural functions, begin the theory of environmental functions and give a complementary focus to the theory of processes that has been developed in precedent papers.

Myth, Language, and Complex Ideologies

Ideologies use for their conservation and propagation persuasive methods of communication: rhetoric. Rhetoric is analyzed from the semiotic and logical-mathematical points of view. The following hypotheses are established: (1) language L is a self-explanatory system, mediated by a successive series of systems of cultural conventions, (2) connotative significances of an ideological advertising rhetoric must be known, and (3) the notion of ideological information is a neutral notion that does not imply the valuation of ideology or its conditions of veracity or falsification. Rhetorical figures like metonymy, metaphor, parable analogy, and allegory are defined as relations. Metaphor and parable are order relations. Operations of metonymic and metaphoric substitution are defined and several theorems derived from these operations have been deduced.

National Parliaments and their Role in European Integration: The EU’s Democratic Deficit in Times of Economic Hardship and Political Insecurity. Bruges Political Research Paper 28/2013

The article describes and assesses the role of national parliaments in EU legislation considering the reforms introduced by the Lisbon Treaty. This is closely connected with the understanding and (political) application of the principle of subsidiarity. After an analysis of the possibilities and limitations of the relevant legal regulations in the post-Lisbon age, alternative ways for participation of national legislators on the European level are being scrutinized and proposed. The issue of democratic legitimization is also interconnected with the current political reforms being discussed in order to overcome the Euro Crisis. Finally, the authors argue that it does not make sense to include national parliaments in the existing legislative triangle of the EU, but instead to promote the creation of a new kind of supervisory body.
