Les symboles et les signes de Noites do Sertão, de João Guimarães Rosa, contient l étude d une édition de cette ouvrage, publié par Livraria José Olímpio Editora, en 1975. Un éditeur arrêtée. Notre priorité c est montrer au lecteur les dégradations résultants d altérations ou d omissions qu on vérifie dans les publications postérieurs; d une manière spécifique, les éditions mais récents. Dans le primiere chapitre, notre recherche privilégie l analyse et l explication de las inscirtions qui sons enregistré dans la partie exterior, ou dans la couverture de ce livre. Le deuxième chapitre traite des réflexions sur ce qui se réfère au revers de la couverture, dans le côté gauche: les énigmes dont l auteur utilise avec l intention de bien idiquer au lecteur orientations pour envisager les aspects des narratives. Combien, nous méditerons ici sur la signification des épigraphes de cette ouvrage; sur les noms des personnages les plus importants et sur la connexion de ce livre avec autres textes littéraires. Dans le troisième chapitre nous explicitons la rélation de contiguïté avec cette ouvrage et le platonisme. O Chapitre quatre s occupe d étudier toutes cettes symboles vérifier ici sur la pérspective de la vision Junguienne (C.G.Jung); et dans le cinq, analysons les relations possibles de cette ouvrage avec autres livres du même écriteur.

O coerentismo de Bonjour: uma leitura fundacional

In The Structure of Empirical Knowledge Laurence Bonjour tries to prove the inefficiency of a foundational explanation as a solution to the skeptical problem. His view is that there are no basic beliefs in the proper sense, that is, beliefs capable of having some justificatory force other than the ones derived by the coherence with other beliefs. We will show that this proposal is not achieved satisfactorily by BonJour, and that a non inferential observational belief in his theory would be more plausible if it were interpreted as being basic in terms of a weak foundational theory.

A inferência causal na filosofia moral de Hume.

Starting from the idea that the result of the Humean analysis of causal inferences must be applied coherently to the remaining part of his work, including its moral theory, the present master thesis aims at investigating whether Hume´s moral philosophy is essentially based on feeling, or whether this would not be rather essentially a consequence of our causal inferences in human actions and deliberations. The main idea consists in showing that our moral inferences, to the extent that they are for Hume empirical , depend on our belief in a connexion between something which has been previously observed and something which is not being observed ( but that it is expected to occur or to be observed in the future). Thus, this very belief must base our moral inferences concerning the actions and deliberations of the individuals. Therefore, must e o ipso induce us to associate actions and behaviors, as well as character and moral claims of men to certain moral feelings. Accordingly, the thesis is unfolded in three chapters. In the first chapter Hume´s theory of the perception is reported as essential part of the explanation or the principles that bind ideas in our mind and constitute our inferences. In the second chapter, the Humean analysis of causal inferences is presented and the way they contribute in the formation of our moral inferences is explained. In the third and last chapter, the formation of our moral inferences and the real contribution of the doctrine of freedom and necessity for the examination or our actions are analysed and discussed.

Hermenêutica existencial em Agostinho de Hipona e Martin Heidegger

The thesis presents interpretations of Augustine of Hippo with regard to the first three chapters of genesis, the first book of the Bible. These interpretation are found in the works Literal Commentary on Genesis, concerning Genesis Against the Manicheans, Literal Commentary on Genesis, Unfinished, Books Xi-XIII of the Confessions, as well a brief exposition in Books XI-XIV of the City of God. Exposition of these Augustinian Commentaries seeks to demonstrate various interpretations made by author in one group of texts revealing a hermeneutics centered in the interpreter and not in established interpretive rules. In sequence there is described succinctly the evolution of textual hermeneutics during the modern period up to the reflections conducted by Martin Heidegger in the first half of the twenties. Based in Heidegger s existential commentaries on the Pauline Epistles (Galatians and I-II Thessalonians) and on the tenth Book of the Confessions, there is shown a return to a interpreter-based hermeneutics, such as practiced by Augustine. The concern manifested by Heidegger with regard to given bases foundations, existent in Dasein, foundations which can influence self-comprehension, constitute themselves in possibilities of explication as much for Augustinian interpretive variations, as for the existential approach applied by Heidegger to the Pauline epistles and Augustine s text

Uma análise teórica da evolução da rotação estelar

In the past 50 years, large efforts have been made toward the understanding of the stellar evolution. In the observational context, large sets of precise measurements of projected rotational velocity were produced, in particular by the Natal and Geneva groups. From these data, it is now possible to establish the behavior of stellar rotation from the turnoff to the red giant branch. In addition, these data have shown the role of tidal effects on stellar rotation in close binary systems. Nevertheless, relatively little attention has been paid to theoretical studies on the evolution of rotation along the HR Diagram, a topic itself directly associated to the evolution of the stars. Basically, there are two reasons for such a fact, (i) spherical symmetry is not assumed, what leads to a substantial increase in the numerical complexity of equations and (ii) non rotating models have been very successful in explaining relevant observational data, including the mass-luminosity relation and chemical abundances. In spite of these facts, it is clear that considerable work remains to be done on the role of rotation in the later stages of the evolution, where clear disagreements arise from confrontations between theoretical predictions and observations. In the present work we study the evolutionary behavior of stellar rotation along the HR Diagram, taking into account constraint conditions issued from recent observational survey of rotational velocity carried out with high precision procedures and new evolutionary codes

Caracterização do ritmo de atividade motora durante a puberdade em sagüis (Callithrix jacchus) sob condições semi-naturais

Most of ontogenetic studies on circadian timing system have been developed on infants, adults and elderly. The puberty has not been a stage of life few studied, except for researches in human adolescents, that presents phase delay in sleep-wake cycle. However, few studies have focused on the basis of this circadian change due to methodological difficulties. Thus, an animal model to study the sleep-wake cycle at puberty is essential. In the common marmoset, a social primate, the circadian activity periodicity stabilizes around 4 months (juvenile stage) and the 8h period component has a seasonal variation. Puberty stage of this species begins near the 8th month of age in males and near the 7th month in females with 7 months of duration. With the aim to characterize the circadian motor activity rhythm during puberty in marmosets (Callithrix jacchus) the motor activity was continuous registered by actiwatches in 6 animals between 5-12 months. Since the social factor influence the behavior of this specie, behavioral observations were realized in 30 minutes windows twice/week to a general evaluation of the influence social interactions dynamic across experiment. Determination of puberty onset was done by fecal progesterone and estrogens in females, and androgens in males. From the analysis of the multiple regression test was selected a model that evaluate age and seasonal variables effect on the activity rhythm according to the higher explanation coefficient. The total activity was the only parameter influenced by age. Moreover, the activity onset was the parameter more explained by the model, and the sunrise was the factor that most influenced it. After the puberty onset, 2 dyads advanced the activity onset. The activity total decreased in 1 dyad and increased in 2 dyads. This increase may be related to the birth of infants in these families. The motor activity circadian component stabilized later in 1 dyad, coinciding with the puberty onset of these animals, while bimodality, caused by the 8 h component, was modulated by seasonality. The agonistic behavior was not evaluated due to reduced number of events. There were changes across ages in affiliative behavior of contact in 1 dyad, grooming done in 1 animal and grooming received in 2 animals. Although there is evidence of puberty effect on the activity motor rhythm, the photoperiodic fluctuations influenced the rhythm. Therefore is not possible to affirm if the puberty modulate the activity rhythm in marmosets

Bem-estar psicológico de servidores e funcionários técnico-administrativos das Instituições de Ensino Superior Públicas e Privadas : indicadores e antecedentes

The elaboration of this thesis aimed at getting to know the structure of the psychological well-being (PWB) at work and analysing the differences in the PWB levels among technical-administrative servants in public and private Institutions of Higher Education (IES) in the municipality of João Pessoa. Two hundred and thirty-three public and private IES male and female servants of João Pessoa participated in the research, replying to an instrument composed of questionnaires referring to the elaborated model. Factorial and regression analyses were accomplished in order to test the hypotheses in respect of the proposed model. The results showed that the PWB related with the work is composed of indicators such as affection, vitality, anxiety, depression, satisfaction at work and aspiration for accomplishment and reduction of the self-efficiency. The observed PWB predictors at work were the IES type, presence of children, age and the escape and back-out facing strategy. These predictors possess relationship of moderation among them in the explanation of PWB. On comparing the PWB experienced by the technical-administrative servants, it was observed that those linked to private IES showed higher PWB rates. Furthermore, there are differences among PWB predictors in accordance with the IES type. The applicability of the results of this thesis is wide as regards social interventions in the search of health improvement under a psycho-sociological perspective. Eventually, the thematic of this thesis intends to reinforce the studies on the worker s health, since by knowing what would lead him into a feeling of accomplishment and well-being will result in more chances of promoting him, while creating opportunities of a sounder life for these people in psychological terms

Trabalho infantil na agricultura :sentidos produzidos pelas mês e pelos professores

Attempts to explain child labor, for the most part, have been reduced to the economic aspect, looking to establish a causal relationship between work and poverty. Without disregarding this aspect, we intend to approach this phenomenon considering other aspects that could be contributing towards its maintenance. We seek, above all, to articulate it with the concepts of disciplinary power and ideology. The present study, therefore, tries to consider these aspects with the intention of learning the reasons that the mothers and the teachers produce concerning child labor in the cultivation of vegetables. We elected these participants because we considered that child labor has been reinforced by the disciplinary institutions and proponents of ideology, the family and the school, here represented, respectively, by the mothers and the teachers. To affect this study, we created focused groups with the mothers whose children are students and work in the cultivation of vegetables in Gramorezinho (neighborhood situated in the northern part of Natal, RN) and with the teachers of the neighborhood school (Escola Lourdes Goudeiro). The discussion of the participants was handled according to the perspective of discursive practices, attempting to articulate them with the notions of ideology and disciplinary power. In general, we perceived how much ideology and discipline are immersed in the discursive practices of the participants. Whereas, even though in some moments the reference to work as being something that takes time from the child to study and play is apparent, the participants attribute great importance to child labor. Both for the teachers and for the mothers, work is something that can free the children from laziness, from becoming criminals and from using drugs. It too constitutes an important alternative to idleness and to the permanence of the child in the streets

A energia e suas implicações no ensino-aprendizagem da química

The area of Education in Chemistry in Brazil has appeared over 30 years and its growth has been accelerated by the need of comprehension of the processes of teaching and learning in chemistry. Many researches, in this area, has among its investigation objects the teaching tools like teaching materials and the learning processes of students in high school and basic education, but when dealing with higher levels of education, they are seldom portrayed. This study aimed to investigate the General Chemistry textbooks with respect to approach the concept of energy; know the main ideas of graduate students in Chemistry on the relation of the concept of energy and chemical transformations; finally, developing a cicle of studies with the proposition of an approach wich inter-relate the concept of energy and its implications in the teaching-learning process of a chemical transformation. To do so, we used as instruments a questionnaire, press conference, conceptual map and experimental activities. All activities of the study cicle were videotaped and recorded, transcribed and the results organized in tables. For the activities of the study cicle texts that have been developed and inter-relating concepts of chemistry and energy, which in turn gave theoretical support to the activities in the cycle. In the analysis it was used as a theoretical content the analysis of Laurence Bardin. The results revealed that the analysis of the book might be perceived that not always the concept of energy is used in order to generate the abstract thought of chemical transformations, but that the main macroscopic thermodynamic variables are present in the explanation of these transformations. During the study cicle, were studied two chemical reactions: the first one, made possible to approach the macroscopic dimension to quantify the concept of energy and the second one, made possible to demonstrate the macro and microscopic dimension of the concept of energy during a chemical transformation. In all reactions proposed, students used, in most of the times, as explanations, only macroscopic observations of the reactions under study and failed to realize that the concept of energy can be used to explain macro and microscopic chemical transformation. As a final action of the study cicle, students requested further discussion, to clarify the link between the concept of energy and the meanings constructed in the process of studying the reactions. This is done through an oral explanation, during the cycle, and registered in this thesis and attempts to show the interrelationship existing conceptual

Método e sociologia em Weber: alguns conceitos fundamentais

Os parâmetros de análise social fornecidos pelos fundamentos da obra weberiana apontam algumas determinações necessárias à análise de fenômenos sociais. Defendendo uma sociologia capaz de compreender os sentidos e conexões presentes nas ações sociais, Weber propõe uma concepção específica de método e de objeto na sociologia, que se assenta na explicação de ações sociais individuais, sob condições determinadas, e busca, ao mesmo tempo, explicitar as significações das instituições sociais, nas quais os indivíduos agem, como resultantes também da ação humana. A partir de tais idéias, o breve ensaio ora apresentado, propõe-se a debater alguns elementos trabalhados nos conceitos weberianos de método e sociologia

Propriedades críticas do processo epidêmico difusivo com interação de Lévy

The diffusive epidemic process (PED) is a nonequilibrium stochastic model which, exhibits a phase trnasition to an absorbing state. In the model, healthy (A) and sick (B) individuals diffuse on a lattice with diffusion constants DA and DB, respectively. According to a Wilson renormalization calculation, the system presents a first-order phase transition, for the case DA > DB. Several researches performed simulation works for test this is conjecture, but it was not possible to observe this first-order phase transition. The explanation given was that we needed to perform simulation to higher dimensions. In this work had the motivation to investigate the critical behavior of a diffusive epidemic propagation with Lévy interaction(PEDL), in one-dimension. The Lévy distribution has the interaction of diffusion of all sizes taking the one-dimensional system for a higher-dimensional. We try to explain this is controversy that remains unresolved, for the case DA > DB. For this work, we use the Monte Carlo Method with resuscitation. This is method is to add a sick individual in the system when the order parameter (sick density) go to zero. We apply a finite size scalling for estimates the critical point and the exponent critical =, e z, for the case DA > DB

Nucleação de vortices em nanoelementos elípticos

The present work reports a theoretical study of the vortex nucleation in elliptical nanoelements of iron with the dimensions of the principal and secondary axes in the range of hundreds of nanometers. It will be divided into three steps: first of all, a general panorama and a justification for the interest of the study of nanosystems and their applications. Second, a explanation about the computational simulations applied for the calculations of the remanent states after the saturation in a external field which value is grater then the exchange field of the material for nanoelements coupled or not to a antiferromagnetic substrate. Systems with that range of axes dimensions and height in the range of a few dozens of nanometers have a natural tendency to nucleate closed magnetic ux, like vortex. Third, we will emphasize the nucleation of double vortex, the main types and the dimensions in which they occur (phase diagram) and the factors that may in uence in the nucleation and control of the remanent state. We shown that we can control specially the distance between the vortex cores changing the value of the interface field. Finally, we present a expectative of continuity of this work with objectives and applications

A geografia no currículo do ensino médio e no vestibular da UFRN: 2001-2007

This work examines the results of the selecting process to enter Universidade Federal do Rio Grande do Norte called Vestibular, in 2001, 2003, 2005 and 2007, in relation to the necessary knowledge presented by the candidates in the Geography area. It observes the contents in the discursive exams and its corresponding results discussing them from the official curriculum of the Secondary School, as it is stated in the official documents of Ministério da Educação(MEC): Parâmetros Curriculares Nacionais do Ensino Médio (PCNEM), Orientações Curriculares Nacionais para o Ensino Médio (OCNEM) e Orientações Educacionais Complementares aos Parâmetros Curriculares Nacionais (PCN+ do Ensino Médio). We aim to highlight what are the contents and background of the Geography curriculum according to the orientations of the official curriculum; discuss in what measure these contents are present in the questions and in the correct answers of the candidates as well as reflect upon what possibly is suggested by those results concerning the knowledge presented in the answers. In this investigation process, the history of the teaching in Brazil is taken up together with the statistical data about the Fundamental School and about Higher Education in the last years. Both map the scenario in which this research takes place as well as make knowledgeable some variables such as: cultural, economical, political and social structures. The discussion takes place between the curriculum and the teaching, Geography teaching and Secondary School in Brazil articulating these variables with the question of accessibility to Higher Education through the Vestibular . Despite the limitations of this research in terms of methodology and deepening of analysis, the results led us to important observations which can contribute to the understanding of that the students´ performance in the Geography examination has several outspreads. These must be thought with scientific exactness in order to avoid any rushed and careless explanations leading to conclusions that may have serious consequences for the teaching systems and the students

A Produção do espaço das pequenas cidades do Seridó Potiguar

The present research wants to comprehend the small towns process of production situated in the Seridó Potiguar, under a historical perspective. Many were the ways passedthrough and the social agents involved in the organization of this space that is build in the treefold: cattle-breeding/cotton plantation/mining, giving origin to the firstcenters. Through the analysis of demographic, economical and social aspects we elaborate a small towns urban profile, considering the 80 s period until today. Those aspects reveal a town s systems with several characteristics and impossible to be insert in some table of reference. These elements are showed in the concentration of urban equipment in the distribution of economical opportunities and in the social connection that are made in the routine of each place. However, the analysis of production s process and special organization proportinated us an explanation of small towns reality, confirming its importance in the urban system, catching sight that, although the restrict urban functions presented, it confirms its towns character by organizing andadministratingthe life specific community
