Este estudo analisa os efeitos da primeira frase da transição para o IFRS no Brasil (Lei 11.638/07 e CPC 13) nos resultados publicados em 2009 (exercício de 2008 e republicações de 2007) pelas empresas listadas na Bovespa. É aplicado o inverso do “Índice de Conservadorismo” de Gray (1980,1988), renomeado “Índice de Comparabilidade” por Weetman et al. (1998), para determinar se e o quanto os resultados reportados pelas novas normas são superiores aos apurados pela norma brasileira anterior – indicando o conservadorismo do sistema contábil brasileiro, previsto por Gray e outros estudos – ou inferiores (otimismo). Reduziu-se gradativamente a amostra inicial conforme a compliance com o CPC 13 e a transparência das demonstrações e das Notas Explicativas. Isso permitiu, após aplicação do Teste de Wilcoxon, verificar em média resultados maiores conforme a nova norma em relação à norma tradicional – preconizando-se que persistirão aumentos até a adoção do full IFRS em 2010. Após o exame de ajustes ao resultado, foi possível relacionar certas inconsistências entre 2007 e 2008 a impactos da crise financeira de 2008 nos ajustes “custos de transação na emissão de títulos” e “valor justo (marcação a mercado) de instrumentos financeiros”.

A matemática, infelizmente e de uma forma errada, ainda é encarada por muitos como uma ciência que é acessível apenas para alguns “iluminados”. Segundo a frase célebre de Paulo Freire, “Não há saber mais ou saber menos há saberes diferentes” e é este tipo de filosofia que é necessário incutir nas nossas escolas e na sociedade. A meu ver, as atividades investigativas vão ao encontro do pensamento de Paulo Freire, uma vez que, neste tipo de atividades, deve ser dado enfoque aos diferentes percursos e saberes. A matemática deveria ser encarada como uma disciplina que educa para a vida – educação matemática. Neste sentido, ela deveria ser trabalhada em diferentes contextos para que os alunos alarguem o seu campo de visão e utilizem a matemática de uma forma crítica e em prol do seu bem-estar. O presente estudo visou compreender de que forma as atividades investigativas contribuem para a aprendizagem significativa da matemática e qual o seu contributo na formação de alunos autónomos e com competências para pensar e agir. A investigação incidiu sobre a prática matemática dos alunos quando realizavam atividades investigativas sobre a unidade temática das semelhanças, nomeadamente, sobre figuras semelhantes, razão de semelhança e critérios de semelhança de triângulos, onde foi utilizada uma metodologia qualitativa de natureza descritiva através da observação participante. O estudo foi efetuado numa turma do sétimo ano e teve por base três propostas de trabalho, sendo que a primeira foi mais de carácter introdutório. Nestas atividades, foram utilizados materiais manipuláveis e o Microsoft Excel no sentido de motivar os alunos e facilitar a compreensão dos conteúdos trabalhados. Os materiais utilizados despertaram um enorme interesse nos alunos, os quais começaram logo a explorá-los, manuseando-os livremente sem qualquer objetivo pré-definido, isto é, antes de se inteirarem do propósito da atividade. As atividades investigativas aliadas aos materiais manipuláveis são uma maisvalia na aprendizagem dos alunos uma vez que o conhecimento é construído de uma forma natural através de um processo espontâneo e dinâmico, consequentemente, significativo. Com a realização de atividades investigativas, são proporcionados aos alunos momentos de exploração e de investigação aleatórios, culminando numa aprendizagem de improviso, no sentido em que esta não obedece a regras pré-definidas e estimula e desenvolve o raciocínio dos alunos.

The spatial and temporal fluidity conditioned by the technologies of social interaction online have been allowing that collective actions of protest and activism arise every day in cyberspace - the cyber-activism. If before these actions were located in geographical boundaries, today's demands and mobilizations extrapolate the location, connect to the global, and at the same time, return to the regional through digital virtuality. Within this context of the relationship between digital technology and global flow of sociability, emerges in October 2010 the social movement of the hashtag "#ForaMicarla", which means the dissatisfaction of cibernauts from Natal of Twitter with the current management of the municipality of Natal-RN, Micarla de Sousa (Green Party). We can find in the center of this movement and others who appeared in the world at the same time a technological condition of Twitter, with the hashtag "#". Given this scenario, this research seeks to analyze how the relationship of the agents of movement hashtag "ForaMicarla", based on the principle that it was formed in the Twitter network and is maintained on the platform on a daily basis, it can create a new kind of political culture. Thus, this study discusses theoretically the importance of Twitter and movements that emerge on the platform and through it to understand the social and political demands of the contemporary world and this public sphere, which now seems to include cyberspace

The present work focused on developing teaching activities that would provide to the student in initial teacher training, improving the ability of mathematical reasoning and hence a greater appreciation of the concepts related to the golden section, the irrational numbers, and the incommensurability the demonstration from the reduction to the nonsensical. This survey is classified itself as a field one which data collection were inserted within a quantitative and qualitative approach. Acted in this research, two classes in initial teacher training. These were teachers and employees of public schools and local governments, living in the capital, in Natal Metropolitan Region - and within the country. The empirical part of the research took place in Pedagogy and Mathematics courses, IFESP in Natal - RN. The theoretical and methodological way construction aimed to present a teaching situation, based on history, involving mathematics and architecture, derived from a concrete context - Andrea Palladio s Villa Emo. Focused discussions on current studies of Rachel Fletcher stating that the architect used the golden section in this village construction. As a result, it was observed that the proposal to conduct a study on the mathematical reasoning assessment provided, in teaching and activity sequences, several theoretical and practical reflections. These applications, together with four sessions of study in the classroom, turned on to a mathematical thinking organization capable to develop in academic students, the investigative and logical reasoning and mathematical proof. By bringing ancient Greece and Andrea Palladio s aspects of the mathematics, in teaching activities for teachers and future teachers of basic education, it was promoted on them, an improvement in mathematical reasoning ability. Therefore, this work came from concerns as opportunity to the surveyed students, thinking mathematically. In fact, one of the most famous irrational, the golden section, was defined by a certain geometric construction, which is reflected by the Greek phrase (the name "golden section" becomes quite later) used to describe the same: division of a segment - on average and extreme right. Later, the golden section was once considered a standard of beauty in the arts. This is reflected in how to treat the statement questioning by current Palladio s scholars, regarding the use of the golden section in their architectural designs, in our case, in Villa Emo

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

The research aimed two objectives: 1st) identifying and describing the metaphors of the inflation, in a corpus of 18 texts of economic journalism, from Joelmir Beting, written in the last trimester of 2002, at the moment of the government s transition of president Fernando Henrique Cardoso to Luiz Inácio Lula Da Silva. 2nd) verifying the recognition of the metaphors by the students of the basic education of a private school from Natal. 91 metaphors had been identified, analyzed in the perspective of the conceptual metaphor s theory, by Lakoff and Johnson (2002), on the basis of the distinction between conceptual metaphor and metaphoric expressions, and between domain-source/domain-target. 10 underlying conceptual metaphors had been inferred, being that the domains-source used more frequently to characterize the inflation had been those ones according to the human being and the animals and, of a less imaginable form, to the ways of transport (car, aircraft). These general conceptual metaphors had been unfolded in other s more specific ones ( animal specifying itself in lion , dragon , dog , etc.). Another result was the identification of metaphoric expressions with two or more meanings , with relation to more than one conceptual metaphor or explicit, in the same expression, two domains-source (for example: armored dragon ) and contributes, of a relevant form, for the semantic struturation of the text. The understanding of the metaphors was verified through an activity of domains-source s identification (10 metaphoric statements and fulfilling of the gap in the phrase the inflation is a/an ) applied in a group of 8th year of the basic education (12-13 years old, with 14 girls and 17 boys) from a school of good social and economic positions from Natal-RN. There weren t great difficulties on the part of the students in recognizing the domains-source involved: about 80% to the great majority of the statements

TEMA: o controle do tamanho da abertura velofaríngea é uma variável importante na caracterização do perfil acústico da fala hipernasal. OBJETIVO: investigar os aspectos espectrais das frequências de F1, F2, F3, formante nasal(FN) e anti-formante, em Hertz, para as vogais [a] e [ã] na presença de aberturas feitas no bulbo de réplicas da prótese de palato de uma paciente com insuficiência velofaríngea. MÉTODO: gravações de produções de quatro palavras (pato/mato e panto/manto) inseridas em frase veículo foram obtidas em cinco condições de funcionamento velofaríngeo: prótese sem aberturas (condição controle: CC), prótese com abertura de 10mm² no bulbo (condição experimental - CE10), com abertura de 20mm² (condição experimental - CE20), com abertura de 30mm² (condição experimental - CE30), e sem prótese (condição experimental aberta - CEA). Cinco fonoaudiólogos julgaram a nasalidade de fala ao vivo, durante a leitura de um texto oral. As gravações foram usadas para análise espectral. RESULTADOS: valores de F1 foram significativamente mais altos para [a] que para [ã] em todas as condições. Valores de F2 para [a] em CE20 e CE30 foram significantemente mais baixos que nas outras condições, aproximando-se dos valores para [ã]. Valores de F3 não foram significativamente diferentes nas diferentes condições. Houve relação entre os achados de FN e anti-formantes e a percepção de nasalidade para as condições CE10 e CE20. CONCLUSÃO: foram observadas mudanças significativas nos valores espectrais estudados de acordo com alterações no tamanho da abertura velofaríngea.
