A esfera como metáfora: representações do futebol no campo da literatura (leituras do tema no conto de ficção)

Football, understood as a phenomenon of sports practice and nearly universal coverage, can also be seen as a game whose operation circumvents the cultural universe of people who practice it. Much more than just a sport, so this game is a cultural phenomenon par excellence, bearing a communicational and aesthetic dimension whose occurrence has been spotted in various fields of scientific and cultural. Therefore, it is as game and as a phenomenon of culture, we intend to focus on football here as an object of study. Our aim is to investigate the sport in Brazil taking the Literature and Journalism as privileged instances of their representation in the media. Thus, the central idea of this research is to show when and how football has become a recurrent theme in Brazilian literature, starting with its journalistic approach until we get an overview of the aesthetic representation of the game, Literature as the main focus of attention and taking the genre of fiction story as material fact of their representation. With this approach, we intend to develop an overall view, overview of the literature about football in our country and at the same time, particularize this vision in some representative authors of it, like the writer-journalist Mario Filho (the historian, essayist on the modernization of chronic specific theme), José Lins do Rego (writer passionate about the game), Nelson Rodrigues (the esthetician that elevated the sport to the status of art by chronic), Lima Barreto (who along with Antonio de Alcantara Machado pioneered the formalized within the fiction) and the storytellers of the topic itself. In the end, we intend to infer the results of evaluations and reviews of books and authors listed, we have examined a wide sense, but also vertical (and which were focused on a socio-historical perspective and critical-aesthetic) within the assumption that seems be a homology between the way football practice amongst us will historically winning characteristics as to form a Brazilian school of football, and how our writers, journalists will be addressing the topic, which also would focus on creating a "Brazilian way" of telling literary football. The proof of this hypothesis operational work together with the development of historiography and the necessity arising from it, creating a "Guide to Reading football theme in fictional tale of Brazil" shut the focal perspective of this study

A morada do pensamento: um encontro com Platão na busca da natureza do sentido em Frege

The ontological investigation of sense, from German philosopher Gottlob Frege s point of view, has, as its foundation, the understanding of reference, representation, thought and sense s categories. According to Frege s writings, On Sense and Reference, and Thoughts Logical Investigations, sense carries itself the solution for the problem of identity s relation. Sense gives us the knowledge s increment that identity doesn t give. But still there is a problem: the definition of sense's nature. Sense couldn t have its nature strictly defined because, in this case, it would be reduced to reference s category and thus, sense would be identified with the own extra-linguistic object, and this is a misconception. But Frege said that thought must be considered as the sense of the sentence. So, with this close relationship between sense and thought, a new goal in this investigation is putt in focus: thought. To Frege, thought is not a simple subjective performance of thinking, it is not a subjective representation, but it is an objective content that is real, eternal, and that exists by itself in a third realm . Thought exists in a realm beyond the world of subjective representations and beyond the world of sensible perception. From this point, the present investigation went back to Plato s World of Ideas. So, the platonic thinking was included in this debate about the metaphysic of the third realm in Frege, trying to clarify the original concepts of knowledge, reality and truth. To achieve this objective, the following dialogues had been included in our research: Theaetetus, Republic and Phaedo. And the following fregean questions had been brought to Plato's scope: how happens the new knowledge? What is the third realm s reality? What is the relation between truth and thought? Doing that we could see as much some of the platonic origins of Frege's approach, as some differences between this two philosophers

Construção de Conceitos Matemáticos na Educação Básica numa Abordagem Peirceana

Peircean semiotic analysis is employed to examine the construction/representation of signs-thinking of 32 early elementary school students regarding the concept of length measurement. The work consisted of developing concepts of standard unit, reading and interpretation of measurement by instruments, so that the mathematical language presented in the concrete materials was being signified and re-signified as a tool for perception and representation of new concepts. The pedagogical triad Feeling-Perceiving, Relating-Concept (F-P/R/C) co-related with the dynamism of the semiosis process, defined by Charles Sanders Peirce (1839-1914) in his semiotic theory on the production of the sign (Object, Representamen and Interpretant), enabled the interpretation and analysis of the students' inferences in the phase of perception (feel, admire), induction (experience), and deduction (concept).

Música dos espaços: paisagem sonora do Nordeste no movimento armorial

This work exams the presence of music in the imaginary constitution of spaces, taking as study s object part of the musical production of the Armorial Movement, officially casted in 1970 in the city of Recife, Pernambuco. From that so called, by the Armorial s discourse, the essence of the brazilian northeastern popular art , the armorialists has intended to make an art that express an idea of northeasternity and brazility . Tries to demonstrate how the music has exerted a basic function of condensation and spreading of the armorial aesthetics, auditorily delimiting the territory of Brazilian Northeastern and, at the same time, trying to impose a sonority to it. This work still analyses the elaboration of what would be a proper soundscape of the Northeastern and how this elaboration passes trough the desire of crystallization of an idealized space, perpetual, escape line of the characteristic modernizing and postmodernizing experience of the twentieth century, product, in turn, of the anxiety of conservation of the Northeastern as a shelter to the traditions that has been evidenced by the construction of an visibility and, also, an audibility to the so called northeastern universe. It analyses, too, the way as works the confrontation between the idea of a so called northeastern soundscape - sonorous events set taken as typical from the rural space - and a sonorous archives series produced since 1920 with the regionalist discourse, showing how was elaborated an armorial music that has intended to represent the brazilian Northeastern. It evidences how, to the elaboration of armorial music, it was managed elements from the European musical culture so called scholar. It argues that the utilization of, to the manufacture of the armorial thinking and aesthetics, of a European mimical capital, so called that way by Stephen Greenblat, was consequence of the intellectual leadership of the Movement, centered in the writer Ariano Suassuna. It argues that Suassuna, followed by the musicians and the artists of the Movement, has searched to evidence a genetic linking between what he has considered the Brazilian true popular art and the medieval Iberian culture. For in such a way, the music was taken as a formation element of the social imaginary and directed to verify a relationship between the Northeastern idealized by the Armorial and the music produced by the Movement. This work has searched, therefore, through the analysis of the armorial music, to study the possible confluences between music and the space that has produced it to, by this analysis, to think the complicity between music and history

Os significados do tabagismo construídos na dinâmica social

The present study has the purpose of catching the significances of smoking in the social dinamics based on the Theory of Social Representations. It was developed among adults with ages from 20 to 59 years, low social and economic conditions, at Natal RN, Brazil. The Free-words Association Test was applied as the instrument of data collection and a semi-structured interview with the smokers and non-smokers, besides a structured interview with smokers, non-smokers and ex-smokers. All data was analyzed by the descriptive statistics using the Analysis of Content Technique of the thematic kind and by the softwares ALCESTE and EVOC 2000. Elaborations about smoking were marked by social, cultural and historical dimension, however they showed sensibility to changes and revealed positive and negative aspects of the habit. The analysis of the semi-structured interviews showed the following categories and under-categories respectively: Initiation of the habit (Friends and Family and Appreciation and Beauty); Psychosocial Implications of smoking (Personal relationship, Work and Financial); Behavior when facing smoking (Positive, Negative and Neutral); Smoking Effects (Smokers´ health and the other people health); Description about oral diseases ( Bad breath, Oral cancer and Dental problems); Smoking treatment (Physician and psychological, Supernatural and Difficulties). ALCESTE analysis presented 4 classes: Ambivalence between pleasure and get ill, Smoking as a trouble and danger to society, Social discrimination of smokers and Mouth as a place of reaffirmation of the discrimination. Those helped us to understand the psychosocial repercussion of the habit. On the social representation structure we identified as a probable central nucleus of the smoker group the categories Pleasure and Bad to the health and as peripheral elements Alcoholic Drink, Financial damage and Nervousness. For the non-smoker group the category Bad to the health comes first and Stop Smoking comes as a peripheral element. Finally, we hope that the knowledge of these representations can contribute to plan and/or to rethink over the professional practices and public policies related to smoking. Besides that, for an amplified comprehension of the study object the discussions over the identified representations should be deepen and amplified to other population and social groups

An efficient Hopfield network to solve economic dispatch problems with transmission system representation

Economic dispatch (ED) problems have recently been solved by artificial neural network approaches. Systems based on artificial neural networks have high computational rates due to the use of a massive number of simple processing elements and the high degree of connectivity between these elements. The ability of neural networks to realize some complex non-linear function makes them attractive for system optimization. All ED models solved by neural approaches described in the literature fail to represent the transmission system. Therefore, such procedures may calculate dispatch policies, which do not take into account important active power constraints. Another drawback pointed out in the literature is that some of the neural approaches fail to converge efficiently toward feasible equilibrium points. A modified Hopfield approach designed to solve ED problems with transmission system representation is presented in this paper. The transmission system is represented through linear load flow equations and constraints on active power flows. The internal parameters of such modified Hopfield networks are computed using the valid-subspace technique. These parameters guarantee the network convergence to feasible equilibrium points, which represent the solution for the ED problem. Simulation results and a sensitivity analysis involving IEEE 14-bus test system are presented to illustrate efficiency of the proposed approach. (C) 2004 Elsevier Ltd. All rights reserved.

Framework for analysis and representation of external systems for online reactive-optimisation studies

The paper proposes a framework for the analysis and representation of external systems for online optimisation studies. The basis for this framework is the equivalent OPF (EOPF), an optimisation model obtained by partitioning of the OPF model. The EOPF is mathematically redefined in the paper to accommodate the concept of a buffer zone. The resulting model is more useful for online optimisation, since external information obtained through intercontrol-centre exchange contracts can be used to improve internal control calculation. Numerical results obtained with original studies involving the boundary-matching procedure have provided a conceptual basis for the definition of a buffer zone for optimisation studies with the EOPF. In the proposed framework, the accuracy of the external representation in optimisation studies is evaluated by comparing the controls obtained by an EOPF procedure with those obtained by the reference-optimisation procedure defined in this paper. The framework is then used to evaluate the accuracy of equivalent optimisation studies involving the IEEE 118-bus test system and the Brazilian South Southeast 810-bus system. The results show that the incorporation of a buffer zone improves the external system representation for all optimisation studies performed.

Alternative proposal for Modal Representation of a Non-transposed Three-Phase Transmission Line with a Vertical Symmetry Plane

The objective of this paper is to show an alternative representation in time domain of a non-transposed three-phase transmission line decomposed in its exact modes by using two transformation matrices. The first matrix is Clarke's matrix that is real, frequency independent, easily represented in computational transient programs (EMTP) and separates the line into quasi-modes a, b and zero. After that, Quasi-modes a and zero are decomposed into their exact modes by using a modal transformation matrix whose elements can be synthesized in time domain through standard curve-fitting techniques. The main advantage of this alternative representation is to reduce the processing time because a frequency dependent modal transformation matrix of a three-phase line has nine elements to be represented in time domain while a modal transformation matrix of a two-phase line has only four elements. This paper shows modal decomposition process and eigenvectors of a non-transposed three-phase line with a vertical symmetry plane whose nominal voltage is 440 kV and line length is 500 km.

Problemas de aprendizagem sobre ligações químicas para estudantes de graduação

This research aims at identifying the learning problems in newly undergraduate students at university, interpreting the nature and causes of these problems, offering subsidies to overcome these difficulties and enabling a meaningful learning through which students give meaning to their learning. As an object for this work was chosen the theme Chemical Bonds - where were studied the forces between atoms to form molecules, compound ions and ionic crystalline structures - and is characterized as one of the most important subjects of Chemistry. In research, it was used a questionnaire with five open questions, answered by 147 students from the early periods of degrees in Chemistry at Universidade Federal do f Rio Grande do Norte. The answers revealed uncertainty on the part of students, both conceptual and representation, with superficial justifications, always using the octet rule to describe models of chemical bonds. Results suggest that these students had inadequate training in high school and that the examinations for entrance into the ranks were made according to flexible criteria less demanding in terms of knowledge. These observations have led to the conclusion that for future changes, it is necessary for high schools and in the early periods in universities favoring the adoption of pedagogical approaches in context and applying strategies to overcome the teaching of superficial memorization on Chemical Bonds, which probably have applied to the teaching of other subjects of chemistry

Cartografia de uma intervenção comunitária para prevenção de DST/HIV/AIDS

Community-based interventions have been presented as a proposal of operationalization of the concept of vulnerability to STD/Aids prevention. This study aimed to analyze the Community intervention developed through the project Strengthening of Community action networks for STD/Aids prevention: know and intervenein, at Mãe Luiza neighborhood, in the city of Natal, State of Rio Grande do Norte, Brazil. The study was conducted in the same location where intervention occurs and took as time reference the first 30 months of construction and deployment process, from April 2010 until December 2012. This is research with qualitative approach, participatory character, developed from the immersion of the researcher in the field, being this community intervention itself. In this perspective, the study approximates to the Cartographic method in which the researcher-researched is engendered in the acts and effects research. The data-generating sources were the memories of the researcher from the field notes, written narratives of subjects involved in the intervention and documents pertaining to the project. In the methodological path of cartography, the image of the rhizome by Deleuze and Guattari (1995) has accompanied the immersion in the field given the nature of research-intervention which approach to the concept of object-Rhizome. The presentation of results was composed for the attempted rhizomatic and a hypertext representation, based on the descriptive narrative taken from the documentary analysis and the multi-faceted narratives with the voices, the looks and the affections narrated by the subject involved, respectively. On the path taken, three lanes were drawn as synthesis of learning produced by experience-that can contribute to understanding the process under study, in his singular character, and reflections on other experiences of community intervention: track 1- Community intervention as active-reflective space and a cause; track 2 Inclusion as power and challenge of community involvement; track 3 Sustainability as A challenge of Community intervention. The study indicates that community intervention is presented as a potential producer of health as also produces practical and creative skills, subjects and inventive in the daily life of the community with a view to reinventing knowledge and practices for the prevention of STD/HIV/Aids

A inserção das mulheres na Câmara Municipal de Natal (1988 - 2004)

This work has as objective to reflect about the insertion of the women in the City Council of Natal in the period from 1988 to 2004. We focused our discussion in the context of the politics of quota that has with objective to decrease the frame of inequalities existent between women and men in the politics, besides of to analyze which the determinants responsible for the women's sub-representation. The research still consists of an analysis of the councilor s women profile and how they were seen in that space of power. We analyzed our study object in a gender vision, since this is related intrinsically the social relationships and the relationships of power. The women, for a long time, they were excluded of the participation in the public life, being just seen as mere expectants. This research is informed mainly by studies which discuss the Gender (Scott, 1990), (Perrot, 1988), (Badinter, 1995), (Bruschini, 2002). We also analyzed the power, politics in the vision of Marx (1996), Foucault (1982) and (Arendt, 2001). We tried to analyze the women's presence in the spaces public and private, showing your conflicts and contradictions faced in the society, focalizing the political character of the women's inclusion in the spaces in that are inserted. The instrument of collection of data was the semi-structured questionnaire, descriptive and analytical - critical. The analyses of the interviews show to the sub-representation of women over the years as a determining factor for these women continue in the invisibility. The women were interviewed councillora ex- bounded from 1988 to 2004. The conclusion the one that we arrived is that this sub-representation has as decisive the patriarchal system that prevailed for a long time in our society and still dominates and affects women in all areas of your life. This becomes more serious in the capitalist society in which prevail the interests of those that it stops the produced wealth

Uma linguagem de modelagem da interação para auxiliar a comunicação designer-usuário

The development of interactive systems involves several professionals and the integration between them normally uses common artifacts, such as models, that drive the development process. In the model-driven development approach, the interaction model is an artifact that includes the most of the aspects related to what and how the user can do while he/she interacting with the system. Furthermore, the interactive model may be used to identify usability problems at design time. Therefore, the central problematic addressed by this thesis is twofold. In the first place, the interaction modeling, in a perspective that helps the designer to explicit to developer, who will implement the interface, the aspcts related to the interaction process. In the second place, the anticipated identification of usability problems, that aims to reduce the application final costs. To achieve these goals, this work presents (i) the ALaDIM language, that aims to help the designer on the conception, representation and validation of his interactive message models; (ii) the ALaDIM editor, which was built using the EMF (Eclipse Modeling Framework) and its standardized technologies by OMG (Object Management Group); and (iii) the ALaDIM inspection method, which allows the anticipated identification of usability problems using ALaDIM models. ALaDIM language and editor were respectively specified and implemented using the OMG standards and they can be used in MDA (Model Driven Architecture) activities. Beyond that, we evaluated both ALaDIM language and editor using a CDN (Cognitive Dimensions of Notations) analysis. Finally, this work reports an experiment that validated the ALaDIM inspection method

Evolution of representation of the hands in plastic arts

A interação entre arte e ciência foi intensa durante o Renascimento, sofrendo declínio nos anos posteriores com retomada significativa no século XX, principalmente com o uso de técnicas de identificação, datação de obras de arte e o desenvolvimento de novos materiais. O relacionamento entre artes plásticas e Cirurgia da Mão mantêm-se intenso , sendo freqüente o uso de reproduções artísticas da mão nas ilustrações de textos científicos. Objetivando compreender o papel da mão nas artes plásticas, reproduções de obras de artes (esculturas e pinturas) representativas de vários estilos ou períodos da história da arte foram analisadas com enfoque no estudo das mãos. Detalhes anatômicos, relacionamento com outras estruturas do corpo humano, papel na composição e aspectos simbólicos das mãos foram estudados no contexto histórico e artístico de obras de arte do período paleolítico (pré-história) até o século XX. A representação da mão nas artes plásticas está diretamente relacionada ao estilo ou período da obra e à capacidade individual de interpretação e execução do artista.

Fotografia e paisagens da modernidade : Currais Novos/RN de 1950 a 1980 / Gênison Costa de Medeiros

This dissertation promotes a dialogue between visual representation and the new cultural geography theory to critically examine the photography representation of an specific urban landscape. The interest here is to explore the ways in which the images of the city of Currais Novos - RN, captured by the photographer Raimundo Bezerra from 1950 to 1980, have taken a great part in shaping people s understanding and imagination of this city s modernizing process. What comes out of this work is the comprehension of that photography permites a geographical study of urban landscape as it can revel perceptions, imaginations, discourses e subjetivities which are based on especific urban cultural dreams and aspirations related to the case studied. So, the aim of this dissertation was to analyse how the discourse of modernity could be seen as part of and impregnated to the urban landscape of Currais Novos by Bezerra s photographs. Then, an intertextual, hermeneutic and phenomenalogical understanding of the geographic object and how it fits within the cultural context was fundamental
