As duas culturas: Antonio Candido e a formação da sociologia e da literatura no Brasil

Antonio Candido, author of fundamental papers to understand Brazil’s cultures process formation, in his works about sociology and literature formation, he draws an explanation of these process of cultural genesis by mean of referential and functional systems, that become possible Brazilian society expression though scientific and literary cultures. These processes and explanations look at for functional correlations between elements and system by mean of relationship between authors-works-receptors, nevertheless, it must to investigate the individual contributions of authors and works to formation of shapes and directions of system.

A questão da colonização no Brasil: historiografia e documentos

In this article we draw attention to the fact that the documentation relating to the decision to colonize Brazil, as well as the early stages of colonization, comprising two interpretations about the reasons to occupy, populate and organize the production on American soil. The Brazilian historiography joined the explanation of that pressure from European nations led to the Portuguese crown decided on an occupation more effectively. But without ignoring this reason, the documentation allows to take into account their own historical circumstances created by the development of trade. These are essential conditions for the emergence and effectiveness of the proposal to colonize Brazil. Thus, when considering only the pressure of European nations the Brazilian historiography remained on the surface of events. It’s necessary to take into account the documentation on what it allows to grasp the colonial process as a historical phenomenon and not just as an act of will.

A importância de Scotus na concepção de história de Arendt

The objective of this study is to discuss the notion of history in Arendt, from the importance that needs the thought of Duns Scotus, particularly with regard to the primacy of the will. For the author, Scotus was a medieval thinkers to emphasize the role of free will as power in the face of intellect attached to the natural activity. The freedom to get an act featuring a world ruled by contingency. Now, for Arendt, that freedom is consistent with your idea of authentic political, and base a public space, defined by word and action of individuals. The history, which takes place from political activity, received various treatments, from Greek antiquity to the modern conception of process. It joined the idealistic conceptions, establishing universal ways of defining the future. However, if freedom is to characterize the vita activa, the history must seek the meaning of the facts to scrutinize their singular aspects, which fell to the continuo of universal explanation of the official history. It is, therefore, to approach the history from the perspective of singular narrative, from the spectators, those who founded the public space. Hence the importance of bipolar concepts such as nature and freedom, necessity and contingency, will and intellect, as Scotus.

Equívocos na leitura da teoria de Jean Piaget

Dans cet article, nous présentons l'analyse des erreurs commises par rapport à l'épistémologie génétique et la psychologie de Jean Piaget. Nous nous appuyons sur un essai publié dans un périodique brésilien concernant la constitution du sujet d’enfance et la théorie de Piaget. Nous avons comme but d’aider à reprendre la «vraie» théorie de Piaget et de donner un aperçu aux lecteurs à fin de ne pas reproduire de telles erreurs ou être confrontés à de différents sens donnés à la même théorie. En ce qui concerne l'analyse, les auteurs du rapport disent que l'homme est le résultat de différents stades de développement et de ses phases. Cependant, en cherchant à expliquer comment les structures logiques deviennent nécessaires, Piaget a affirmé de ne pas rien avoir inventé. Il a conclu que la constitution des structures opératoires est le résultat de l'interaction du sujet avec le milieu, à condition qu'il dispose de certaines conditions prealables et qu’il soit capable d' établir ses rapports De cette manière, s'il a identifié des moments de la psychogenèse cognitive, il l’a fait grace à la constatation de que les sujets, dans cette interaction avec le milieu, finissaient par construire des manières qualitativement différentes de comprendre et gérer la réalité. Ainsi, Piaget n'a pas cherché de mettre les individus dans des phases ou périodes, artificiellement. Une autre erreur est celui de considérer que Piaget soit adepte de la dicotomie normalité/ anormalité. Ses préoccupations sont de nature épistémologique, et s'il est parvenu à formuler une psychologie, cela avait comme but de donner une base scientifique à sa théorie de la connaissance. Encore une autre confusion a lieu quand on affirme que Piaget a identifié les enfants aux peuples primitifs. Il a seulement dit que la nécessité d’entrer en relation avec le milieu est égale pour l'homme primitif comme pour celui d'aujourd'hui; par conséquent, le fonctionnement est le seul élément biologique considéré par Piaget, vu que tous les êtres vivants cherchent à s’adapter à la réalité. D’après cet angle, on constate que, de la même manière que l’homme primitif a été un enfant - comme ceux d’aujourd'hui - il a cherché à interagir avec le milieu à fin d'assurer sa survie. Il arrive que ses demandes étaient élémentaires du point de vue logico-mathématique, contrairement à nos jours. Une autre erreur consiste à dire qu'il a soupçonné ou admis que les processus de pensée reconnaissaient une organisation logique. Il ne s’agit pas de soupçon ni d'admission, mais d´une nécéssité. Faute de cette fondation, tout le bâtiment piagétien s’effondrerait. Nous concluons que le concept de progrès et l'état de l'intelligence sous-entendent la critique des auteurs. Malgré cela, et même pas sans admettre les explications formulées par Piaget, c’est le fait de que les censeurs doivent faire face à une vérité: indépendamment de la culture ou du moment historique, les enfants agissent toujours de la même manière, en cherchant à donner un sens à la réalité. Nous pouvons donc être d’accord ou en désaccord avec l'explication de Piaget. Cependant, il y a quelque chose qui ne doit pas être ignorée: la contribution apportée par Piaget vers la compréhension de la logique du fonctionnement mental.

Efeitos preventivos do treinamento físico na expressão das proteínas Cox-2 e Vegf de ratos tratados com dexametasona

Dexamethasone is a synthetic glucocorticoid widely used to treat allergic and inflammatory processes. This drug is used in three main situations, are used to contain acute or chronic inflammatory processes, or like immunosuppressive drug's. In these cases the patient will receive high doses for a chronic period and, therefore, has a much greater chance of adverse side effects, such as hypertension, diabetes and dyslipidemia. Dexamethasone promotes deleterious effects on the arachidonic acid pathway, when administered in high doses, because it is a potent anti-inflammatory drug. We recently demonstrated that dexamethasone significantly reduces the protein expression of vascular endothelial growth factor (VEGF) in both skeletal muscle and heart, but the mechanisms involved remain unclear. Meanwhile, exercise has been shown to be effective against high blood pressure, diabetes and dyslipidemia, promoting, among other factors, the increase in VEGF and angiogenesis. One possible explanation for these effects would be the creation of new vessels mediated by inflammation, or by the stimulation of the formation of products of the metabolism of arachidonic acid (AA), such as prostaglandin E2 (PGE2) and VEGF, by increasing the stimulation of the enzymes cyclooxygenase 1 and 2 (COX-1 and COX-2). Little is known about the preventive effects of training on the action of dexamethasone in the arachidonic acid pathway. Therefore, the aim of this study was to determine whether aerobic exercise training, performed before and concomitant treatment with dexamethasone, was able to prevent the effects of the dexamethasone in the protein expression of COX-2 and VEGF. For this, we used young Wistar rats (n = 40) which were randomly divided into 4 groups: sedentary control (SC), sedentary and treated with dexamethasone (SD), trained control (TC) and trained and treated with dexamethasone (TD). These rats performed aerobic exercise training, 60% of maximum capacity, 5

Movimento dos olhos e controle postural

The control of stances such as the upright stance seems not to have a purpose in itself; this control could facilitate the execution of other simultaneous tasks, the so-called suprapostural tasks. The goal of this study was to determine the effects of saccadic eye movements on the control of posture. Twelve adult participants had their body oscillations analyzed while standing upright, for 70 s, in the postural conditions of feet apart and feet together, performing fixation in the central target or horizontal saccadic movements, in the conditions slow (0,5 Hz) and fast (1,1 Hz). The results showed that saccadic movements, independently of their frequency, strongly reduced trunk and head oscillations in the anterior-posterior (AP) axis. In this axis, there was an effect of feet position only in head oscillation. In the medio-lateral (ML) axis, the results showed a strong effect of feet position with body oscillation decreased in the condition of feet apart. The effect of the visual task in the ML axis occurred only for trunk oscillation, not reaching significance level in the pairewise comparisons. In the AP axis, the data corroborate a facilitatory explanation of the control of posture: the reduction in body oscillation limited the variations of the stimulus image projected on the retina, facilitating the execution of saccadic movements as compared to fixation. In the ML axis, the effect of reducing the basis of support was more evident than the effect of saccadic movements, suggesting that the available resources were used primarily for the postural task in detriment of the visual task. Additionally, aspects like attentional focus and sensory information pick up are discussed as mechanisms involved in this task

O legado de Descartes

The criticism of Cartesian philosophy is correlated on four pillars: the fragmentation of knowledge, the separation between mind and body, the impossibility of the reductionist method for explanation of natural phenomena, and in the superiority of the reason as the only valid form of knowledge. These last two pillars, as many environmentalists claim, contributed decisively to the devaluation of the res extensa over the res cogitans. To check this we used as a theoretical framework the following texts: Discourse on Method, Rules for Conduct of the Spirit and Metaphysical Meditations. By reading these works it was found that the first two pillars (the fragmentation of knowledge and the separation between mind and body) there are no theoretical basis in texts. The failure of the reductionist method to explain the ecological and atomic phenomena and the overcoming of reason as the only valid form of knowledge are supported in their philosophy.

Um estudo sobre a intervenção com o professor de educação física para a inclusão educacional do aluno com deficiência visual

It was aimed to identify how the physical education teachers worked to include a student with visual impairment; intervene with the teacher from the identified necessities and assess the intervention. Data were collected in three stages: 1) Weekly monitoring and filming the classes, 2) intervention by the reflection of videos coming from the previous step and suggesting new actions, 3) development of filming for evaluating the intervention. Before the intervention, it was identified that the explanation of the activities happened collectively. It was held the physical help as the first form of instruction, the student with visual impairment participation occurred depending on the company of a classmate who held hands and did the activities together. Along the intervention it was reflected about the structure of the classes, the ways of explanation of the activities and the strategies and the resources to assure an enjoyable participation of students with visual impairments. The training of peer tutors was a strategy used. After the intervention it was identified in the classroom the assistance of the trained peer tutors; the maintenance of oral explanation and demonstration, though, the first way to explanation for the student with visual impairment started to be the oral tip.

Criança não é manga, não amadurece: conceito de maturação na teoria histórico-cultural

The idea of "mature development" is based, frequently, on explanations of school failure: the student does not learn because he is immature and the school has to wait until he gets "mature". When one says that a child is not mature compared to the development already attained by an adult, one focuses only the quantitative differences between them and forgets that these new qualities of the adult did not arise by the maturation, but by the permanent appropriation process of the human culture. Thus, this idea of "maturity of development" expresses a deep biologization of the human being, reducing social and educational problems explanation to the biological apparatus of the individual. The purpose of this essay is to analyze the relationship between maturation and development, pointing out the limits of biologists’ explanations of human phenomena and the possibilities of explanation formulated by the historical-cultural theory to the organization of pedagogical work. This concept gives a new configuration to the role of maturation in the learning process and gives the school education a central role in the development of higher psychological functions. Thus, the school does not have to wait for the child’s maturation. Rather, it is its duty to create conditions for his/her maturation to become effective.
