A abordagem histórica do letramento: Ecos da memória na atualidade

The word literacy acquired a polysemy spectrum which put it away from the notion of social and historic process, at the same time that associates it to codification and decodification of writing. Concerning to this last perspective, we would have nothing to add. However, we sustain, in this paper, considering Pêcheux´s Discourse Analysis and Lacanian Psychoanalysis approaches, that there is a conception of literacy as a phenomenon which influences indirectly individuals and cultures for whom the competence of writing is not established. In this sense, the concept of literacy is larger than alphabetization. As an evidence of this proposal, we analyze a text written by a student, that demanded him to write about a context distant from his own, and, to do so, he mobilized places from the archive and from his particular memory, showing a singular knowledge of writing culture, even though his text presents interpenetration of oral an writing forms, aspect that is not allowed by those who defend an a-historical conception of literacy. We discuss that the student’s text ran away from the reduction of a merely pedagogic ideology and reflects a discursive coherence in face of the challenge that was proposed to him. By the end of this paper, we propose that the teachers should search for devices that make easier for their students to write texts in which their authorship could emerge.

Por uma abordagem funcionalista da complementação oracional

The main goal of this paper is to demonstrate the relevance of adopting a functionalist model which integrates aspects of both the main and completive clause to describe the phenomenon of clausal complementation. It is adopted the Functional Discourse Grammar theoretical framework which, unlike most approaches to the theme, focusing only on properties of the main clause, allows the analysis to combine functional aspects of both the main and the complement clauses. As a result of the discussions, the study highlights the importance of integrated analysis like this one for a broader comprehension about the formfunction relations in Portuguese complement constructions.

Geometria de thurston;uma abordagem utilizando Topologia Computatcional

Algoritmos para reconhecimento de 3-variedades utilizam-se do conceito de superfície normal, sendo assim, pode-se então tratar problemas de teoria de 3-variedades como sendo de programação linear. Como exemplos tem-se o Algoritmo de reconhecimento da 3-esfera triangulável de Rubinstein-Thompson que é implementado na suíte de software Regina, como a decomposição soma conexa de 3-variedades. A completa classificação de 3-variedades pode ser realizada por meio de algoritmos, possuindo assim relevância para o Programa de Geometrização de Thurston para obtenção de resultados inicialmente utilizando topologia computacional. O objetivo do presente trabalho é discorrer sobre uma aplicação do software Regina. Obteve-se durante a elaboração do presente trabalho, o resultado entre a comparação da 3-esfera homológica de Poincaré com a 3-esfera, parte importante para o entendimento da Conjectura de Poincaré e do Programa de Geometrização.

Máximos e mínimos na geometria euclidiana: uma abordagem histórica

The goal of this work is to perform a historical approach of important results about maxima and minima, on Euclidean geometry, involving perimeters, areas and volumes. As a highlight, we can mention the Dido’s isoperimetric problem and the Papus’s problem about the wit of the bees. In this context, with a concern didactic, we tried to use, whenever possible, the geometry classical formulas to the calculus of areas. On the other hand, in the case of isoperimetric inequality the techniques of differential and integral calculus became more suitable for our purposes.

O conflito ideológico no discurso sobre a maconha: uma abordagem dialógica de matérias impressas veiculadas na mídia brasileira

According to data published on the World Drug Report 2012 by Unodc - United Nations Office on Drugs and Crime -, the world consumes nowadays the same amount of illicit drugs that it has always consumed. Contrary to this stable consumption, discussions surrounding the issue of drugs have intensified. The greatest controversies and the largest repercussion in the Brazilian media relate to marijuana use. This paper was developed in the context of polemic issues and its general goal is to analyze the conflict of ideologies present in the discourses about drugs on printed articles released by the Brazilian media, represented here by the magazines Veja, Carta Capital and Galileu. This study is carried out based on a dialogic approach, supported by the Bakhtinian researches on discourse

Contos de fadas e sequências didática: uma abordagem no ensino fundamental II

The proposal of this work is based on the elaboration of didactic sequences from fairy tales, for students of Elementary School, during reinforcement classes of Portuguese language. It is deemed appropriate to use this genre, because it gives to the child and to the adolescents a pleasurable reading, approaching them of playful situations. As a main goal of this work, this research aimed the preparation of didactic sequences using fairy tales in the classroom, as well as encouraging the reading for these students. The intention was also the internalization of the narratives and the messages conveyed by them, associating them to everyday situations. We used the deductive method, in which we initially organized the approach in the classroom and the teaching sequences from theoretical assumptions and materials already designed

Estabilização de enzimas: uma abordagem

Enzyme stabilization is one critic point in basic and applied enzymology. The increasing interest in applying enzymes in industrial processes has fostered the search for biocatalysts with new properties or extreme stability. Enzyme stabilization can be achieved by different methods: isolating enzyme variants from organisms living in appropriate extreme environments (extremozymes), by protein engineering, chemical modification, use of additives, immobilization. This brief review aims to give a better understanding of those methods employed for enzyme stabilization.
