Análise da estabilidade do movimento rotacional de satélites artificiais com quatérnions e sob a influência de torques externos

The aim of this work is to analyze the stability of the rotational motion’s artificial satellite using the Routh Hurwitz Algorithm (CRH) and the quaternions to describe the satellite’s attitude. This algorithm allows the investigation of the stability of the motion using the coefficients of the characteristic equation associated with the equation of the rotational motion in the linear form. The equations of the rotational motion are given by the four cinematic equations for the quaternion and the three equations of Euler for the spin velocity’s components. In the Euler equations are included the components of the gravity gradient torque (TGG) and the solar radiation torque (TRS). The TGG is generated by the difference of the Earth gravity force direction and intensity actuating on each satellite mass element and it depends on the mass distribution and the form of the satellite. The TRS is created by changing of the linear momentum, which happens due to the interactions of solar photons with the satellite surface. The equilibrium points are gotten by the equation of rotational motion and the CRH is applied in the linear form of these equations. Simulations are developed for small and medium satellites, but the gotten equilibrium points are not stable by CRH. However, when some of the eigenvalues of the characteristic equation are analyzed, it is found some equilibrium points which can be pointed out as stables for an interval of the time, due to small magnitude of the real part of these eigenvalue

Os movimentos nas redes e em redes: das manifestações internacionais ao Movimento Prudente

Neste trabalho apresentamos uma leitura sobre o processo de articulação dos movimentos em redes e do uso das redes sociais pelos movimentos socioespaciais que mais se destacaram no mundo nos últimos cinco anos. Tendo suas bases nos marcos conceituais de movimentos socioespacial, movimentos socioterritorial, Rede e Redes Sociais, remontamos ao processo de formação da Via Campesina e das manifestações na Primavera Árabe, M12M, M15M, Occupy Wall Street, Movimento Passe Livre e o Movimento Prudente na escala local. Analisar e comparar estes movimentos e suas manifestações nos permitiu identificar a conexão entre a difusão de informações nas redes sociais e a materialização das manifestações no espaço público. Destaca-se que o uso destas tem acarretado em uma nova dinâmica não só na difusão de manifestação, mas também na realização de trabalho de base, caracterizando-se como um importante espaço de socialização política da atualidade

A relação entre a escola e a família do jovem: um estudo em duas escolas públicas

Faço parte do grupo de estudos sobre Jovens, Violência e Educação que desenvolve o estudo que procura compreender os modos de inserção da escola no bairro e os modos de inclusão dos jovens na comunidade e na própria escola. Os objetivos gerais do estudo são caracterizar os modos de inserção das escolas e dos jovens no bairro, o imaginário dos jovens sobre a escola, sobre seus projetos de vida e a prevenção da violência escolar. A participação neste grupo de pesquisa fez com que interesse se direcionasse à temática família, escola e comunidade. Assim sendo constituem-se objetivos específicos deste estudo: investigar a relação escola/família. Este estudo foi feito em duas escolas da periferia da cidade de Rio Claro- SP. Essas escolas atendem alunos moradores na região que pertencem aos extratos sócios econômicos mais baixos da população. O bairro é conhecido na cidade como violento, com ocorrências de assassinatos, tiroteios, brigas e presença do tráfico de drogas. Tanto é que este bairro é considerado área prioritária pela Prefeitura Municipal de Rio Claro – SP para intervenções que objetivem a prevenção da violência de jovens. Os dados coletados por meio de questionários e entrevistas foram pelo grupo com alunos do 8º ano e 9º ano do ensino fundamental e 1º ano do ensino médio. Esses dados serão analisados neste estudo

A oferta de vagas em escolas de educação infantil nos municípios de até 10000 habitantes do estado de São Paulo

Este estudo está vinculado ao Grupo de Estudos e Pesquisas em Política Educacional, GREPPE (grupo interinstitucional) – Seção Rio Claro, mais precisamente ao Projeto de Pesquisa intitulado “A oferta educacional na educação infantil: arranjos institucionais entre o público e o privado”, coordenado pela Profª Drª Raquel Fontes Borghi que trata sobre a oferta de vagas das escolas de Educação Infantil no estado de São Paulo. O presente estudo pretende analisar as relações entre o público e o privado, buscando perceber se o repasse de subsídios às instituições conveniadas (com ou sem fins lucrativos) pelas prefeituras municipais representa uma política pública educacional efetiva para a oferta de vagas na Educação Infantil. Para o estudo serão analisados os municípios denominados “muito pequenos”, com população máxima de até 10 mil habitantes. A pesquisa será qualitativa, bibliográfica e documental, realizada através de entrevista previamente estruturada em forma de questionário, anexo ao final deste relatório, por meio de telefonemas e e-mails e referendado por outros estudos já concluídos no GREPPE. Após a coleta de dados, os mesmos serão analisados através de bases teóricas relacionadas ao assunto e convertidos no relatório de pesquisa para o Trabalho de Conclusão de Curso

O que acontece durante o recreio em duas escolas da cidade de Jaú com crianças do 2º e 3º ano do ensino fundamental

This work had how I aim to notice what it happens in the recreation of two schools of basic teaching I, more precisely with children of the 2nd and 3rd year, analysing what they do and since they play. The interest in observing this moment is the fact of, at present, the children they have not many places to play, principally due to the violence and gradually places with structure for the same thing; the streets are already not any more places where the child can play the friends calmly, interact with other, his turn discovers the world and principally to enjoy itself. With these facts the school becomes the most appropriate place so that the child can play and interact with other children and at the same time to be protected leaving so the most carefree parents. The school becomes the great back yard in the life of the child, when several activities are happening there more and in this way developing not only the communication, the spirit of collaboration and of companionship, the co-ordination motora in general and the autonomy. Therefore the recreation makes an important time into the school life, moment in which the child can practise the universal right that is secured of playing

Democracia e participação nas escolas públicas brasileiras: as possibilidades da eleição direta para gestores escolares

After a long period of military dictatorship, the Brazilian people, following the redemocratization in the late 1980s, experimented the possibility of electing their political representatives. This experience of democracy and citizenship included in the electoral process, now, appear as one of the main challenges to make the Brazilian public schools more democratic and participative, through the election of school managers. The purpose of this paper is to discuss the historical aspects of the process of electing representatives in Brazil and the possibilities of direct elections for school managers. At first recovering the struggle of the Brazilian society in search of an effective political participation and, subsequently, pointing out the limits and possibilities of the introduction of direct elections for school managers as a mechanism to consolidate a more democratic school.

Saberes profissionais de professores e gestores de creches e pré-escolas

This article discusses data obtained through a qualitative study carried out from 2012 to 2013, the aim of which was to investigate the knowledge of teachers and managers of Early Childhood Education regarding laws and documents published in Brazil since 1980, geared towards this stage of Basic Education. The results suggest that subjects have a knowledge of the laws and documents relating to Early Childhood Education, but that there are major gaps that could affect their practices in nurseries and pre-schools, and the construction of their professional identities

Escolas públicas no campo: retrospectiva e perspectivas em um contexto de projetos políticos em disputa

In present article, we present reflections on the process of closing public schools in the countryside in Brazil. Through bibliographical survey, as well as documental research, we carried out a retrospective analysis of the historical moment in which the implementation of policies of mass education directed to people living in rural areas occurs. We have also sought to raise socio-political-economic aspects of the moment in which the process of closing these schools is intensified. The results obtained suggest possible implications of this closure policy, in addition to indicating some of the challenges posed to the public policy of education in the country; for example, the Brazilian federal context and the budget limitations imposed to subnational governments with regard to the funding of school education, particularly in relation to small municipalities and/or municipalities with low tax revenues. This situation quite often occurs because these municipalities present reduced budgets, depending largely on transfers of financial resources from other spheres of the Government, either federal or state, the so-called intergovernmental budgetary transfers; namely, the Municipalities Participation Fund. Such issues demand the resumption of debates about the federative pact, in particular with regard to fiscal federalism, given that the financial capacity of each subnational government is crucial to the implementation of educational policies.

A legislação escolar brasileira e a organização da álgebra no Ensino Fundamental

This work aims to investigate the presence of algebra in Brazilian school legislation, from 1980 to the present day. The research was developed through qualitative research, with phenomenological approach, using hermeneutic procedures for the analyzes of legal texts. Survey data were obtained through a survey about the educational legislation, specifically referring to the elementary school, guided by the question how is the presence of algebra in brazilian school legislation that organizes the elementary school?. In possession of the data, the analyzes were carried out considering the historical, social and political environment in which the laws were introduced, focusing the educational landscape of the time, as well as the movements that influenced the teaching of mathematics in the country. The analysis of each text -law were arranged in a row explanatory tables of a meta understanding about the observed. The meta understanding of the documents was drawn up on the basis of the convergence of analyzes that resulted in nuclear ideas of the law texts. At the end a comprehensive synthesis is presented, outlining the movement in which algebra is inserted in schools, through the educational legislation

Experimentação no ensino de física: um estudo escolas estaduais na região de São José dos Campos

This work presents the results of a study on the use of experimentation in physics teaching, presenting a survey on the use of this strategy in public high schools in the region of São José dos Campos. Data collection was carried out in schools by means of questionnaires prepared for physics teachers and students from three grades of high school. Data were obtained in eighteen schools distributed in the city of São José dos Campos (two in the central region, in the west, three on the east side, seven in the north and five in the south), a school in the district of Sao Francisco Xavier and a school in the town of Monteiro Lobato. Thus, data from 20 schools, 610 students and 20 teachers were analyzed. Among the main results, we highlight that over 80% of the students said that there is no physics lab at the school where they study, and less than 1% declares that uses laboratory weekly. We note that there is a laboratory in 25% of the schools in the northern region and 10% or less of the other schools. According to the students the proposition of the experimental activities by teachers is rare - only three schools in East Side the options sometimes and always exceeded the number of responses experimental activities are never proposed. We had 60% of the teachers who reported using the curriculum of the state of São Paulo to propose activities to students, and half of the teachers said they did not have classes experimental physics classes in initial training or had them in sufficient quantity to support the use of this feature in practice
