Brincar, atividade humana e ferramenta pedagógica no contexto escolar da região metropolitana de natal

This thesis talks about the use of guided educational tools in play and playful in public schools in the Metropolitan Region of Natal (MRN), contributing to the teaching and students learning of basic education in the contents of portuguese and mathematics. We assume that the play is an activity / human need and therefore implies the proper development of children in physical, psychological, biological, cultural, social and historical aspects. We consider the mediation exercised by the teacher in the classroom, and the affection existing between teacher and student, sine qua non terms, so that the truth and fact of the process of teaching and learning occur. Thus, theoretically collaborated Paulo Freire, with his dialogical vision; Lev S. Vygotsky says that we learn and why we develop; Lev S. Vygotsky that states that we learn and for that we develop ourselves; Pierre Bourdieu and the concept of habitus, as something embedded and therefore procedural, and the cultural capital that needs to be fed and (re)meaning at school; Luiz Pereira, Bernard Lahire, Gilles Brougère and others brought their theoretical contributions. The empirical field of research was composed by the Municipal School Professor Ulysses de Góis, located in the neighborhood of Nova Descoberta in Natal, and the Municipal School José Horacio de Góis, located in the community of Guanduba, in São Gonçalo do Amarante, municipalities of the Metropolitan Region of Natal (MRN). We used as methodology the collaborative-action-research as a possible of effective participation of the research subjects, imputing them a voice and performance in the process, and not considering them just observers. The results indicate the effectiveness of the pedagogical tools in play and playful to the learning of students, but that alone is not able to solve all the problems of the school, other referrals need to be secured, as the planning of the actions to be developed in the school and in the classroom, systematized pedagogical orienttion for faculty, family participation/involvement in the school life of students, among other actions that need to be weighted so that education fulfills its role and promote the emancipation of the subject, because in the freireana liberating perspective, "the reading of the world preced the lecture of the word"

O trabalho do gestor escolar: intensificação e implicações administrativas e pedagógicas na gestão da escola

Analyze the work of the school manager who now faces the changes experienced in school management for the last two decades. We propose that there have been changes in school management that have generated a larger number of activities to be developed by managers, causing both the intensification of work and a greater involvement of professionals in the financial-administrative dimension of their work in opposition to the political and pedagogical dimension. This study has a historic-critic approach. That is why we performed semi-structured interviews with school managers of the city schools in Natal RN, BR as a methodological procedure. We also analyzed the literature as well as the documentation relevant to this subject. From the study it was possible to conclude that changes in the field of school management and also teaching have led to an intensification of work of school managers and that such changes have not been followed by corresponding improvement in working conditions and teaching career of these professionals. They, as a rule, are considered by controlling agencies and by the school community as the primarily responsible for the school condition and for creating actions or projects that may improve the institutional objectives and results, including even the maintenance of the institution. Moreover, the growing number of administrative activities represents for obvious reasons extra work for these managers, who, when trying to cope with the growing bureaucratic situations, end up misplacing other political and educational aspects of school work, which may undermine the final purpose of school itself. We stress that we must broaden the discussions on the functions of the school manager, so that this worker can actualize a pedagogical project more committed to an emancipatory nature, despite all the challenge in keeping the school running in often-precarious conditions

O silenciamento no texto jornalístico e a construção social da realidade

This research analyses the silencehood use by the A República journal (Natal/RN), today not being distributed, during the Second World War. Its objective is to unveil the production condition of the news texts, and it was observed that the use of silencehood as a speech strategy with its implications that falls upon the way of behaving and thinking of the society, all that time, influencing the reader in the construction of his image of the reality. During the coverage of the conflict by the local journal it was possible to also observe different speech marks that represented the change in attitude of the Brazilian Government, responsible for the control of what was spread as news. The country lived the dictatorship of the New State and as the war went on the government changed its speech, according to political, social and economical interest s thoughts being played, silencing themes in the name of the national security. We admit as research material journalistic texts that refer to the main facts that occurred during the six years of the world conflict and that is why we used as theoric-metodological support the Speech Analysis

Acionamento de frames e esquemas no processo de construção de sentidos no padrão discursivo charge por alunos do ensino médio

Our research has as goal to describe and analyze the main processes related to the activation of conceptual domains underlying the comprehension in the discourse pattern cartoons by the students of third grades of high school, at Professor Antonio Basílio Filho School. Theoretically, we are grounded on assumptions of Conceptual Linguistics, whose interest analyzes our cognitive apparatus in correlation with our socio-cultural and bodies experiences. We intend to check how is the process of meaning construction and integration of various cognitive domains that are activated during the reading activity. That s why, we take the concept of cognitive domains as equivalent to the structures that are stored in our memory from our sociocultural and corporeal experiences and they are stabilized, respectively, through the frames and schemas. The activation of these conceptual domains, as evidenced by our data, supports the assumption that previous knowledge from our inclusion in specific sociocultural contexts, concurrently with the functioning of our sensory-motor system are essential during the construction activity direction. With this research, we still intend to present a proposal confront the expectations of responses produced by students from the activation of frames and schemas with our predictions

Ser orientador em programas de pós-graduação em educação: uma descrição fenomenológica

Este estudo descreve pesquisa sobre o que é ser orientador em programas de pós-graduação em educação, desenvolvida com oito professores orientadores do Programa de Pós-graduação em Educação da Universidade Federal do Rio Grande do Norte. Trata-se de uma pesquisa qualitativa, com base no fenômeno que é situado, tendo como interrogativo: O que é ser professor orientador? Como se exerce a função de orientador? Os dados empíricos foram produzidos por meio de entrevista, cuja intenção é apresentar os modos existenciais que os professores orientadores produzem na experiência de orientar e a identificar como se exerce a função de professor orientador. Nossa tese é de que o ser orientador só pode ser constatado a partir da experiência, não de comportamento sob tutela de um mundo pré-concebido, ao contrário, ao existir no mundo da educação é que se cria o seu estofo existencial. O referencial teórico da fenomenologia de Merleau-Ponty, em especial, a obra Fenomenologia da Percepção dá sustentação a este estudo. Os dados produzidos a partir dos depoimentos dos professores orientadores revelam que ser orientador é estar junto, aprender, abrir horizontes, lidar com a pressão do sistema, com a singularidade da condição humana, um tipo de atividade em que você cresce, aprende, decepciona-se, sente-se importante como em outras ocorrências da vida. A relação entre orientador/orientando deve ser de empatia e não se reduz apenas a uma troca de conhecimentos, mas de afeto, por isso muitas vezes dramática, incluindo as projeções de ambos. Não defendemos que não seja necessária uma formação que atenda às demandas específicas da atividade de orientação. Pelo contrário, uma prática educativa requer interlocuções, entender o que nos acontece, o que fez e por que fez, o que deu certo ou não, é dividir a vida vivida, em um projeto que tenha como estofo o existir humano e suas possibilidades de vir-a-ser.

O agravo de petição como provimento recursal adequado para impugnar sentenças, decisões interlocutórias e despachos-decisórios na execução trabalhista

A idéia central nasceu em função da atividade profissional. Assistindo no dia-a-dia a dificuldade daqueles que, inconformados com um ato praticado na fase de execução de um processo do trabalho, não encontram, com a segurança desejada, um provimento judicial adequado para submeter a apreciação de tal ato a uma decisão colegiada. Cabe agravo de petição, no prazo de 8 (oito) dias, das decisões do Juiz ou Presidente, nas execuções. Isso é o que consta da legislação específica. Problema dos mais sérios na interpretação desse comando é saber o que são “decisões” proferidas na execução trabalhista, que podem ser impugnadas por meio do recurso de agravo de petição. Essa problemática encontra-se inserida dentro de um contexto processual, daí porque tivemos que seguir um roteiro iniciando com noções básicas de processo, como instrumento utilizado pelo Estado para o exercício de sua função jurisdicional. Saindo do geral para o particular, chegamos no processo do trabalho e suas fases, nos atendo mais na de execução, como ela inicia e termina. O cerne da questão é a reação à execução, os meios reagentes, em especial o recurso, como uma decorrência do princípio do duplo grau de jurisdição, sendo ou não uma garantia constitucional. De acordo com a previsão legal, esse recurso é o agravo de petição. Tratamos dele e dos atos que o juiz pode praticar na execução trabalhista, dizendo da natureza de cada um deles. Cuidamos das decisões interlocutórias, registrando nossa preocupação quanto à dificuldade que temos para sua identificação, mormente na fase de execução. Abordamos, na parte final do trabalho, a matéria relacionada com a possibilidade ou não de recurso contra uma decisão interlocutória, ilustrando esse estudo com alguns exemplos baseados em casos concretos e a solução que foi dada a cada um deles.

Characteristics, complexation and analytical methods of darunavir

What is it? Darunavir is a protease inhibitor used in the treatment of HIV infection. It is an important drug of therapy cocktail for patients infected with the virus. On the market there are darunavir ethanolate tablets of 75, 150, 300, 400, 600 and 800mg, because this is the most stable form. It is commercialized by Janssen-Cilag with the name PrezistaTM. Why we started? This drug has low water solubility and poor bioavailability, therefore requires administration in doses relatively high to the success of the therapeutic effect. The complexation of drugs by using cyclodextrin is welcome in this respect to improve the solubility and hence increase the dissolution rate of poorly soluble drugs. A monograph about this compound has not been described, thus it is an extremely important quality control of darunavir to demonstrate its effectiveness and safety. What we did? Some existing analytical techniques have been discussed in this manuscript, focusing on bioanalytical and pharmaceutical quality control applications. What we found? This review showed the published analytical methods reported for the determination of darunavir and discuss about its characteristics and complexation with cyclodextrin.

O rádio e as matemáticas: um estudo sobre o Projeto Minerva

According to our conceptions, to study the so called Projeto Minerva (PMi) – an action of Brazilian Military Dictatorship, implemented in the 1970s, which intended to provide access to Primary and Secondary Schools for thousands of Brazilians throughout the country, using a cheap, and at that time a widely -spread medium, the radio – implies to study not only a unique education strategy, but a variety of circumstances that allows it to be created and developed throughout its 10 years of existence in various Brazilian locations. Each circumstance, each region, each way of doing of each person involved in its development constitutes a different Minerva – that’s why we choose the plural to treat it: the Minerva ProjectS. In this paper we present one of the many possible histories about such project. Synthetically, we present some historiographical aspects of its creation, development and extinction and, based on a study about one of its lessons (related to Analitic Geometry), we try to evidence differences between a spoken mathematics and a written mathematics. According to the the oretical framework used in this text, inspired by the Wittgenstein's language philosophy, the Project articulates various mathematics, what is different of saying that the project deals with the "usual" Mathematics merely changing the way of communicate it.

COMMENSAL RODENTS

The evolution of effective rodent control has been greater in the past 20 years than during the previous 200 years. Mankind need no longer fear the "black death," typhus, and other rodent-borne diseases. Likewise, there is no longer any reason why we must bear the cost of serious economic losses because of commensal rodent damage to property. Unfortunately, the latter still totals many millions of dollars each year. Damage and contamination of food products by house mice now probably equals or exceeds that caused by rats.

Extractive summarization using complex networks and syntactic dependency

The realization that statistical physics methods can be applied to analyze written texts represented as complex networks has led to several developments in natural language processing, including automatic summarization and evaluation of machine translation. Most importantly, so far only a few metrics of complex networks have been used and therefore there is ample opportunity to enhance the statistics-based methods as new measures of network topology and dynamics are created. In this paper, we employ for the first time the metrics betweenness, vulnerability and diversity to analyze written texts in Brazilian Portuguese. Using strategies based on diversity metrics, a better performance in automatic summarization is achieved in comparison to previous work employing complex networks. With an optimized method the Rouge score (an automatic evaluation method used in summarization) was 0.5089, which is the best value ever achieved for an extractive summarizer with statistical methods based on complex networks for Brazilian Portuguese. Furthermore, the diversity metric can detect keywords with high precision, which is why we believe it is suitable to produce good summaries. It is also shown that incorporating linguistic knowledge through a syntactic parser does enhance the performance of the automatic summarizers, as expected, but the increase in the Rouge score is only minor. These results reinforce the suitability of complex network methods for improving automatic summarizers in particular, and treating text in general. (C) 2011 Elsevier B.V. All rights reserved.

A spectroscopic and photometric study of MSP companions in Galactic Globular Clusters

This Thesis is devoted to the study of the optical companions of Millisecond Pulsars in Galactic Globular Clusters (GCs) as a part of a large project started at the Department of Astronomy of the Bologna University, in collaboration with other institutions (Astronomical Observatory of Cagliari and Bologna, University of Virginia), specifically dedicated to the study of the environmental effects on passive stellar evolution in galactic GCs. Globular Clusters are very efficient “Kilns” for generating exotic object, such as Millisecond Pulsars (MSP), low mass X-ray binaries(LMXB) or Blue Straggler Stars (BSS). In particular MSPs are formed in binary systems containing a Neutron Star which is spun up through mass accretion from the evolving companion (e.g. Bhattacharia & van den Heuvel 1991). The final stage of this recycling process is either the core of a peeled star (generally an Helium white dwarf) or a very light almos exhausted star, orbiting a very fast rotating Neutron Star (a MSP). Despite the large difference in total mass between the disk of the Galaxy and the Galactic GC system (up a factor 103), the percentage of fast rotating pulsar in binary systems found in the latter is very higher. MSPs in GCs show spin periods in the range 1.3 ÷ 30ms, slowdown rates ˙P 1019 s/s and a lower magnetic field, respect to ”normal” radio pulsars, B 108 gauss . The high probability of disruption of a binary systems after a supernova explosion, explain why we expect only a low percentage of recycled millisecond pulsars respect to the whole pulsar population. In fact only the 10% of the known 1800 radio pulsars are radio MSPs. Is not surprising, that MSP are overabundant in GCs respect to Galactic field, since in the Galactic Disk, MSPs can only form through the evolution of primordial binaries, and only if the binary survives to the supernova explosion which lead to the neutron star formation. On the other hand, the extremely high stellar density in the core of GCs, relative to most of the rest of the Galaxy, favors the formation of several different binary systems, suitable for the recycling of NSs (Davies at al. 1998). In this thesis we will present the properties two millisecond pulsars companions discovered in two globular clusters, the Helium white dwarf orbiting the MSP PSR 1911-5958A in NGC 6752 and the second case of a tidally deformed star orbiting an eclipsing millisecond pulsar, PSR J1701-3006B in NGC6266
