Pełny tekst źródłaThis thesis focuses mainly on online matching problems, where sets of resources are sequentially allocated to demand streams. We treat them both from an online learning and a competitive analysis perspective, always in the case when the input is stochastic.On the online learning side, we study how the specific matching structure influences learning in the first part, then how carry-over effects in the system affect its performance.On the competitive analysis side, we study the online matching problem in specific classes of random graphs, in an effort to move away from worst-case analysis.Finally, we explore how learning can be leveraged in the scheduling problem

Este trabalho, ligado à linha de pesquisa “Políticas Públicas, Organização Escolar e Formação de Professores”, teve por objetivo investigar e comparar as representações sociais de estudantes do Curso de Pedagogia da FCT/UNESP e dos professores formados em Cursos de Pedagogia, sobre os alunos dos anos iniciais do Ensino Fundamental da rede municipal de ensino, analisando sua percepção sobre a interferência dessas representações no desenvolvimento do trabalho docente. Para atingir esse objetivo, procuramos responder às perguntas: Que representações sociais os estudantes do Curso de Pedagogia e os professores possuem do aluno dos anos iniciais da escola pública com os quais trabalham ou poderão vir a trabalhar? Estas representações apresentam diferenças após o início da prática docente? Elas podem interferir no desenvolvimento do trabalho docente? Apoiamo-nos, para o desenvolvimento desse trabalho, na teoria das representações sociais de Serge Moscovici. A partir do nosso referencial teórico coletamos os dados necessários, junto aos participantes da pesquisa, por meio de questionário contendo solicitação de evocações sobre “aluno ideal” e “aluno da escola pública” e questões objetivas e subjetivas, permitindo uma triangulação para confirmação das representações pesquisadas. A análise dos dados coletados possibilitou-nos identificar as representações sociais de estudantes do Curso de Pedagogia e dos professores sobre os alunos das séries iniciais da rede pública municipal e refletir sobre os aspectos cognitivos, comportamentais/afetivos e socioculturais nelas contidos. Em seguida analisamos as expectativas docentes nascidas das representações e sua possível influência no sucesso escolar do aluno, valendo-nos da teoria da profecia autorrealizadora...
The present paper is connected to the research line entitled “Public Policies, Scholar Organization and Teachers’ Formation”. The main of this study is to investigate and compare social representations of Pedagogy students’ from FCT/UNESP and teachers’ graduated at Pedagogy about elementary school students from municipal schools. Besides, it aims to analyze how their perception interferes into their practice. In order to reach such objectives we intended to ask the following questions: What social representations Pedagogy students and teachers have about elementary school students from municipal schools with whom they will work? Are such representations different after they start to work as teachers? Can they interfere into teachers’ work? The theoretical base of this paper is Social Representations Theory by Serge Moscovici. The data were collected through questionnaire with objective and subjective questions related to the “ideal student” and the “student from public school”, which provides us to investigate the researched representations. Through data analysis it was possible to identify social representations of Pedagogy students’ and teachers’ about elementary school students from municipal schools. Thus, it was also possible to think about cognitive, behavior/affective and sociocultural aspects inserted into such representations. After that, we analyzed teachers’ expectations brought from their representation and the its possible influence in students’ scholar success, according to self-performing theory ...

A experiência profissional e os impasses enfrentados no cotidiano de trabalho atual, quando se trata de crianças com algum diagnóstico a serem incluídas na escola regular, instigaramnos a realizar o presente estudo. Partindo do princípio de que a inclusão implica no trabalho de toda instituição escolar é que buscamos na Pedagogia Institucional sustentação para nossa pesquisa. A Pedagogia Institucional, corpo de conhecimentos teóricos que, articulado a prática pedagógica, transforma a classe num laboratório de trabalho constante vem a ser a perspectiva da leitura da prática da Escola de Educação Infantil e Ensino Fundamental Centro Integrado de Desenvolvimento - CID. Os sujeitos foram todos os profissionais e professores desta escola, os alunos do último ano da educação infantil, alunos da primeira série e alunos da última série do ensino fundamental, os pais e uma profissional da Escola Nossa Senhora do Bom Conselho, escola que recebe alunos egressos do CID. Os dados coletados constituíram os seguintes focos de análise: 1. A escola como promotora da unidade. 2. A escola como promotora da autonomia. 3. A troca com os pais. 4. A escola como promotora do diálogo com a sociedade. 5. O trabalho em grupo. 6. A escuta como exercício da ética. 7. A equipe interdisciplinar como suporte. 8. A prática da avaliação. Após analise e discussão reflexiva, consideramos que o cerne da inclusão é a prática instituída no cotidiano da escola e, pensamos que a relevância desta pesquisa está na possibilidade de contribuir com aqueles setores que pretendem instituir a inclusão.
Professional experience and difficulties faced in the routine of current work, concerning children with some kind of diagnostic to be included in the regular school, encouraged us to accomplish the present work. Our work is supported by Institutional Pedagogy for we think that inclusion is the work of the whole school institution. Institutional Pedagogy, theoretical knowledge which when related to pedagogical practice turns the classroom into a laboratory of constant work, is the perspective from what practiced is understood at the Elementary and Middle school CID (Centro Integrado de Desenvolvimento). The subjects were all professionals and teachers from this school, students from the last grade of elementary school and from the first and last grade of middle school, parents and one professional from Bom Conselho school, which admits students from CIC. The collected data were related to the following focus of analysis: 1. The school as unity provider; 2. The school as autonomy provider; 3. Connections between parents and school; 4. The school as dialogue provider in the society; 5. The group work; 6. Hearing as ethics exercise; 7. The interdisciplinary team as support and 8. Evaluation practice. After the analysis and discussion, we have considered the practice instituted in the school routine the key for the inclusion. We think that the relevance of this study is in the possibility of contributing to those sectors which intend to institute the inclusion.

Avaliamos a infiltração coroa-ápice da bactéria Enterococcus faecalis em incisivos centrais bovinos instrumentados e obturados com os cimentos endodônticos AH Plus, Endofill, Epiphany, Acroseal e o cimento experimental à base do Polímero da mamona (Polifil). Foi confeccionado um dispositivo a ser adaptado na porção inferior de tubos de centrífuga, Eppendorf. As raízes, previamente obturadas, foram inseridas nesse dispositivo até que 5mm se projetasse para fora do tubo plástico. A junção entre o tubo e a raiz foi selada com araldite, assim como a porção da raiz, externa ao recipiente, excluindo-se 1 mm ao redor do forame apical. O dispositivo Eppendorf e raiz obturada foram fixados em frasco tipo penicilina, contendo caldo .Brain heart infusion.. Com auxílio de uma pipeta, 1mL da bactéria foi transferido ao caldo B.H.I. e 400 µL de uma cultura recente foram transferidos para a porção superior do tubo. Durante 64 dias, a infiltração bacteriana era detectada através da turvação do caldo. Os resultados foram submetidos à análise estatística. Foi utilizado o método não-paramétrico de Kaplan-Meier e o teste de Kruskal-Wallis, complementado por comparações múltiplas pelo teste de Dunn. Adotou-se o nível de significância de 5%. Os cimentos AH Plus e Endofill apresentaram resistência à infiltração bacteriana significativamente menor do que o Polifil, mas estatisticamente equivalentes entre si. Os cimentos Epiphany e Acroseal deram resultados intermediários e equivalentes, mas sem diferença estatisticamente significante em relação aos outros cimentos.
This study compared some of the endodontic sealers sealing ability (AH Plus, Epiphany, Acroseal, Endofill and Polifil (a castor oil-based experimental sealer) using the active lateral condensation technique, through a bacterial test, during 64 days. One hundred bovine incisors were selected and divided into five experimental groups and two control groups (negative and positive ones). The teeth were cleaned and shaped by the step-back technique, then, they were filled with the endodontic sealers and stored in (100%) wet environment. The roots were impermeabilized with araldite glue, adapted into an eppendorf microtube and sterilized by ethylen oxide gas. The root/ eppendorf microtube was added to penicillin flasks containing 6mL of BHI broth kept at 37º C for 4 days to confirm sterilization. After this period, 400µL of Enterococcus faecalis ATCC 29212 were inserted at the upper portion of the eppendorf microtube. Daily leakage was evaluated through the broth turbidy. The results were submitted to the statistical analysis (Kaplan-Meier method as well as Kruskal-Wallis´ and Dunn´s tests). AH Plus and Endofill sealers were statistically equivalent concerning the sealing property, showing less resistance to the bacterial leakage than Polifil, while Acroseal and Epiphany had similar and intermediate behavior, but without numerical significance when compared to the other sealers.

Mapas de produtividade de milho e de soja gerados por um sistema comercial de monitoramento de colheita para as safras de 1998, 1999 e 2000 foram estudados e submetidos a um processo de classificação através da técnica de análise de agrupamento para o conjunto de dados dos três anos reunidos em uma imagem composta. Objetivou-se, a partir dos agrupamentos obtidos, associar algumas tendências de variação no comportamento da produtividade que pudessem caracterizar essas regiões com comportamentos diferenciados dentro da área. Com o auxílio de um levantamento de atributos físicos e químicos do solo e outros conjuntos de informações, foi verificada a possibilidade de relacionar a variabilidade desses atributos com as sub-regiões que se pretendia identificar na área, ou se os fatores climáticos, como os índices de precipitação pluviométrica, podiam demonstrar alguma influência na produtividade em virtude da variabilidade espacial dos atributos de solo nestas sub-regiões.

Yield maps analysis, into precision farming context, is one of the resources used in order to understand and manage the spatial variability of crop's yield and quality. Corn and soybean yield maps obtained from a commercial yield mapping system for three seasons (1998, 1999 and 2000) were studied and classified by a clustering analysis technique using all seasons dataset mixed in a composite image. The aim of this project was to associate some variation trends on the yield behavior to the clusters obtained, in order to characterize these regions with different behaviors within the area. Using a dataset of physical and chemical soil characteristics from a grid soil survey, it was verified the possibility of relating the soil attributes variability to the sub-regions identified in the area. It was still investigated if rainfall index could demonstrate some influence on yield due to spatial variability of the soil attributes on these sub-regions. It was used a geostatistical software for studying the dependence level and the spatial variability framework of yield and soil attributes data. Soil attributes mapping, as well yield behavior analysis and its classification by the clustering analysis were made using a geographical information system (GIS). The results showed that the yield datasets expressed a consistent spatial dependence, which correlation distances ranged from 30 to 40 meters. The spatial variability degree expressed by the structural semivariance contribution index (%C) achieved a high variability level to Corn on 1998 season and medium variability on Soybean 1999 and Corn 2000 season. The clustering analysis technique applied to the three yield maps datasets became possible split the area in four sub-regions. The combination of the maps classified by yield levels allowed defining four yield behavior classes expressively related to the obtained... (Complete abstract, click electronic address below).

Para cada ciclo, foram obtidos dados relativos às produções médias de biogás, apresentados sob forma de totais semanais, em m3 e em valores acumulados para cada substrato. Foi feita a modelagem estatística, a partir dos tratamento definidos, utilizando-se do modelo Gompertz de regressão não-linear, segundo duas linhas metodológicas distintas. Inicialmente, foram considerados modelos de regressão não-linear somente com um componente determinístico e, posteriormente, com dois componentes (mistura). Foram estudadas as propriedades amostrais dos estimadores através de simulações sob a ótica distribucional. A aproximação de uma Gompertz do modelo estatístico proposto para o volume de biogás para os três tipos de camas de frangos mostrou-se adequada em todas situações experimentais, permitindo estimar os parâmetros envolvidos no modelo, utilizando-se técnicas não-paramétricas. O modelo com mistura de duas Gompertz proporcionou bom ajuste aos dados, mas com dificuldades de convergência no processo de estimação dos parâmetros, no qual ocorreu a heterocedasticidade dos erros, isto é, a parte aleatória do modelo não teve variância constante.
In this work, the Gompertz model was used to fit the biogas production in batch biodigestor obtained from the anaerobic digestion of three poultry litter kinds (elephant grass, elephant grass + wood shavings and wood shavings). Two strategies of modeling was proposed, i.e., using one and two (mixture) deterministic components in the statistical models. Results showed that Gompertz model with just a deterministic component fits very well, and allowed to compare the estimated parameters among the poultry litter kinds by nonparametric techniques . Although the models with the mixture fits better than the other one, there are some problems with the convergence processes and the parameter estimation.

Esta pesquisa trata da Formação Inicial de Professores de Matemática, em particular sobre o uso de tecnologia informática. Sabendo da problemática existente nos cursos de graduação, como, por exemplo, a desarticulação entre teoria e prática, entre formação universitária e realidade escolar, deteve-se na seguinte questão: Quais são as perspectivas, expectativas e dificuldades que os futuros professores apresentam quando refletem sobre uma prática educativa utilizando planilhas eletrônicas na escola básica?. A pesquisa contou com a participação de dois futuros professores de Matemática da UNESP de Rio Claro. Foram realizados três encontros de planejamento, dez encontros de intervenção em uma escola pública, e dez encontros de reflexão, que ocorreram sempre após cada intervenção. Os licenciandos tiveram a oportunidade de expor suas idéias sobre as experiências realizadas e, a partir de uma análise à luz do referencial teórico, foram extraindo temas que se referem às suas expectativas, perspectivas e dificuldades. Entre eles, a gestão da sala de aula e a transposição de conteúdo, a complexidade da sala de aula, como eles percebem os alunos, as condições de trabalho na escola, ser professor e o uso de tecnologia informática.
This research addresses the pre-service mathematics teacher education, in particular their practice with computer. Considering the problems concerning teacher education courses - as, for instance, the disarticulation between the theory and the practice, and between the university education and the school reality - it was formulated the following research question: What are the perspectives, expectations and difficulties that the future teachers experience when they reflect on an educational practice using spreadsheets at the basic school? The research was developed in collaboration with two future mathematics teachers from UNESP at Rio Claro, São Paulo, Brazil. It was organized three planning meetings, ten intervention meetings in a public school, and ten reflection meeting, that always took place right after each intervention meeting. The reflection meetings were videoed and transcribed. The data were analyzed with reference to the literature. Themes were identified that could be referred to their expectation, perspectives, and difficulties. These themes included: the teaching in the classroom and the transposition of the contents; the complexity of the classroom environment; the interaction with the students; the school working conditions; being a teacher; and the use of computers.

Compressed gas driven shock tubes have become popular as a laboratory-scale replacement for field blast tests. The well-known initial structure of the Riemann problem eventually evolves into a shock structure resembling a Friedlander wave. In this thesis, we develop an analytical model to predict its key characteristics: location where the wave first forms, peak over-pressure, decay time and impulse. The approach is based on combining the solutions of the two different types of wave interactions that arise in the shock tube after the family of rarefaction waves in the Riemann solution interacts with the closed end of the tube. The results of the analytical model are verified against numerical simulations obtained with a finite volume method. The model furnishes a rational approach to relate shock tube parameters to desired blast wave characteristics, and thus constitutes a useful tool for the design of shock tubes for blast testing.

Technology development is hard for management to understand and hard for practitioners to explain, however it is an essential component of innovation. While there are standard and predictable processes for product development, many of these techniques don't apply well to technology development. Are there common processes for technology development that can make it predictable, or is it unpredictable like basic research and invention? In this thesis, after building a foundation by looking at product development processes, I survey some of the literature on technology development processes and compare them to a handful of case studies from a variety of industries. I then summarize the observations from the cases and build a generic model for technology development that can be used to provide insights into how to monitor and manage technology projects. One of the observations from the product development literature is that looping and iteration is problematic for establishing accurate schedules which becomes one of the fundamental disconnects between management and engineering. Technologists rely heavily on iteration as a tool for gaining knowledge and combined with other risks, technology development may appear "out of control". To mitigate these risks, technologists have developed a variety of approaches including: building a series of prototypes of increasing fidelity and using them as a form of communication, simultaneously developing multiple technologies as a hedge against failure or predicting and developing technologies they think will be needed outside of formal channels. Finally, I use my model to provide some insights as to how management can understand technology development projects. This gives technologists and non-technical managers a common ground for communication.

Computational models of complex phenomena are an important resource for scientists and engineers. However, many state-of-the-art simulations of physical systems are computationally expensive to evaluate and are black box-meaning that they can be run, but their internal workings cannot be inspected or changed. Directly applying uncertainty quantification algorithms, such as those for forward uncertainty propagation or Bayesian inference, to these types of models is often intractable because the analyses use many evaluations of the model. Fortunately, many physical systems are well behaved, in the sense that they may be efficiently approximated with a modest number of carefully chosen samples. This thesis develops global and local approximation strategies that can be applied to black-box models to reduce the cost of forward uncertainty quantification and Bayesian inference. First, we develop an efficient strategy for constructing global approximations using an orthonormal polynomial basis. We rigorously construct a Smolyak pseudospectral algorithm, which uses sparse sample sets to efficiently extract information from loosely coupled functions. We provide a theoretical discussion of the behavior and accuracy of this algorithm, concluding that it has favorable convergence characteristics. We make this strategy efficient in practice by introducing a greedy heuristic that adaptively identifies and explores the important input dimensions, or combinations thereof. When the approximation is used within Bayesian inference, however, it is difficult to translate the theoretical behavior of the global approximations into practical controls on the error induced in the resulting posterior distribution. Thus, the second part of this thesis introduces a new framework for accelerating MCMC algorithms by constructing local surrogates of the computational model within the Metropolis-Hastings kernel, borrowing ideas from deterministic approximation theory, optimization, and experimental design. Exploiting useful convergence characteristics of local approximations, we prove the ergodicity of our approximate Markov chain and show that it samples asymptotically from the exact posterior distribution of interest. Our theoretical results reinforce the key observation underlying this work: when the likelihood has some local regularity, the number of model evaluations per MCMC step can be greatly reduced, without incurring significant bias in the Monte Carlo average. We illustrate that the inference framework is robust and extensible by describing variations that use different approximation families, MCMC kernels, and computational environments. Our numerical experiments demonstrate order-of-magnitude reductions in the number of forward model evaluations used in representative ODE or PDE inference problems, in both real and synthetic data examples. Finally, we demonstrate the local approximation algorithm by performing parameter inference for the ice-ocean coupling in Pine Island Glacier, Antarctica. This problem constitutes a challenging domain for inference and an important application in climate science. We perform simulated inference, comparing synthetic data to predictions from the MIT General Circulation Model, a state-of-the-art ocean simulation. The results reveal some information about parameter sensitivity, but we ultimately conclude that richer data is necessary to constrain the model parameters. In this example, applying our approximation techniques reduced the cost of the inference by a factor of five to ten, taking weeks instead of months, providing evidence that our techniques can make Bayesian inference on large-scale computational models more tractable.

The embezzlement and corruption scandal surrounding the director of a local Massachusetts housing authority in late 2011 spurred a heated public debate about governance and efficiency in the state-funded public housing system. Governor Patrick, state agency heads, public and affordable housing professionals and experts and tenant advocates debated the degree to which the system should be centralized. Eventually, this debate was framed within the parameters of two opposing bills submitted to the state legislature. The Legislature's Committee on Housing took up the issue in June 2013 and will submit a third bill, widely considered to be the decisive measure, towards the end of the 2014 session. Tenant interests were largely absent in this debate. While existing regulations require housing authorities to encourage and fund local tenant organizations, many tenant representatives face retaliation from administrators. In this documentary film thesis, tenants whose organizing efforts have been suppressed discuss how they support one another, overcome stigma and advocate for the interests of their neighbors.

According to the WHO/UNICEF Joint Monitoring Programme (JMP), 14% of the population in Ghana use improved sanitation facilities and 59% use shared facilities. The objective of this thesis is to offer a situational analysis of public sanitation in Ghana by addressing both access to sanitation and bio-digestion on-site waste treatment for one non-profit organization, Pure Home Water, to improve access to sanitation in the Northern Sector of Ghana. Based on the neighborhood, customary, and political context of Ghana, I recommend the construction of new public sanitation facilities, the conversion of existing household toilets to the biodigester systems, and making bio-digester systems a standard technical model while creating local ownership of the technology. In addition, I recommend evaluating the status quo to address the needs of vulnerable groups, addressing hygiene needs as standard, and appealing to the local government's business sense.

Foi confeccionado um dispositivo a ser adaptado na porção inferior de tubos de centrífuga, Eppendorf. As raízes, previamente obturadas, foram inseridas nesse dispositivo até que 5mm se projetasse para fora do tubo plástico. A junção entre o tubo e a raiz foi selada com araldite, assim como a porção da raiz, externa ao recipiente, excluindo-se 1 mm ao redor do forame apical. O dispositivo Eppendorf e raiz obturada foram fixados em frasco tipo penicilina, contendo caldo .Brain heart infusion.. Com auxílio de uma pipeta, 1mL da bactéria foi transferido ao caldo B.H.I. e 400 µL de uma cultura recente foram transferidos para a porção superior do tubo. Durante 64 dias, a infiltração bacteriana era detectada através da turvação do caldo. Os resultados foram submetidos à análise estatística. Foi utilizado o método não-paramétrico de Kaplan-Meier e o teste de Kruskal-Wallis, complementado por comparações múltiplas pelo teste de Dunn. Adotou-se o nível de significância de 5%. Os cimentos AH Plus e Endofill apresentaram resistência à infiltração bacteriana significativamente menor do que o Polifil, mas estatisticamente equivalentes entre si. Os cimentos Epiphany e Acroseal deram resultados intermediários e equivalentes, mas sem diferença estatisticamente significante em relação aos outros cimentos.
Abstract: This study compared some of the endodontic sealers sealing ability (AH Plus, Epiphany, Acroseal, Endofill and Polifil (a castor oil-based experimental sealer) using the active lateral condensation technique, through a bacterial test, during 64 days. One hundred bovine incisors were selected and divided into five experimental groups and two control groups (negative and positive ones). The teeth were cleaned and shaped by the step-back technique, then, they were filled with the endodontic sealers and stored in (100%) wet environment. The roots were impermeabilized with araldite glue, adapted into an eppendorf microtube and sterilized by ethylen oxide gas. The root/ eppendorf microtube was added to penicillin flasks containing 6mL of BHI broth kept at 37º C for 4 days to confirm sterilization. After this period, 400µL of Enterococcus faecalis ATCC 29212 were inserted at the upper portion of the eppendorf microtube. Daily leakage was evaluated through the broth turbidy. The results were submitted to the statistical analysis (Kaplan-Meier method as well as Kruskal-Wallis' and Dunn's tests). AH Plus and Endofill sealers were statistically equivalent concerning the sealing property, showing less resistance to the bacterial leakage than Polifil, while Acroseal and Epiphany had similar and intermediate behavior, but without numerical significance when compared to the other sealers.

Mapas de produtividade de milho e de soja gerados por um sistema comercial de monitoramento de colheita para as safras de 1998, 1999 e 2000 foram estudados e submetidos a um processo de classificação através da técnica de análise de agrupamento para o conjunto de dados dos três anos reunidos em uma imagem composta. Objetivou-se, a partir dos agrupamentos obtidos, associar algumas tendências de variação no comportamento da produtividade que pudessem caracterizar essas regiões com comportamentos diferenciados dentro da área. Com o auxílio de um levantamento de atributos físicos e químicos do solo e outros conjuntos de informações, foi verificada a possibilidade de relacionar a variabilidade desses atributos com as sub-regiões que se pretendia identificar na área, ou se os fatores climáticos, como os índices de precipitação pluviométrica, podiam demonstrar alguma influência na produtividade em virtude da variabilidade espacial dos atributos de solo nestas sub-regiões.

Abstract: Yield maps analysis, into precision farming context, is one of the resources used in order to understand and manage the spatial variability of crop's yield and quality. Corn and soybean yield maps obtained from a commercial yield mapping system for three seasons (1998, 1999 and 2000) were studied and classified by a clustering analysis technique using all seasons dataset mixed in a composite image. The aim of this project was to associate some variation trends on the yield behavior to the clusters obtained, in order to characterize these regions with different behaviors within the area. Using a dataset of physical and chemical soil characteristics from a grid soil survey, it was verified the possibility of relating the soil attributes variability to the sub-regions identified in the area. It was still investigated if rainfall index could demonstrate some influence on yield due to spatial variability of the soil attributes on these sub-regions. It was used a geostatistical software for studying the dependence level and the spatial variability framework of yield and soil attributes data. Soil attributes mapping, as well yield behavior analysis and its classification by the clustering analysis were made using a geographical information system (GIS). The results showed that the yield datasets expressed a consistent spatial dependence, which correlation distances ranged from 30 to 40 meters. The spatial variability degree expressed by the structural semivariance contribution index (%C) achieved a high variability level to Corn on 1998 season and medium variability on Soybean 1999 and Corn 2000 season. The clustering analysis technique applied to the three yield maps datasets became possible split the area in four sub-regions. The combination of the maps classified by yield levels allowed defining four yield behavior classes expressively related to the obtained... (Complete abstract, click electronic address below).

Resumo: A experiência profissional e os impasses enfrentados no cotidiano de trabalho atual, quando se trata de crianças com algum diagnóstico a serem incluídas na escola regular, instigaramnos a realizar o presente estudo. Partindo do princípio de que a inclusão implica no trabalho de toda instituição escolar é que buscamos na Pedagogia Institucional sustentação para nossa pesquisa. A Pedagogia Institucional, corpo de conhecimentos teóricos que, articulado a prática pedagógica, transforma a classe num laboratório de trabalho constante vem a ser a perspectiva da leitura da prática da Escola de Educação Infantil e Ensino Fundamental Centro Integrado de Desenvolvimento - CID. Os sujeitos foram todos os profissionais e professores desta escola, os alunos do último ano da educação infantil, alunos da primeira série e alunos da última série do ensino fundamental, os pais e uma profissional da Escola Nossa Senhora do Bom Conselho, escola que recebe alunos egressos do CID. Os dados coletados constituíram os seguintes focos de análise: 1. A escola como promotora da unidade. 2. A escola como promotora da autonomia. 3. A troca com os pais. 4. A escola como promotora do diálogo com a sociedade. 5. O trabalho em grupo. 6. A escuta como exercício da ética. 7. A equipe interdisciplinar como suporte. 8. A prática da avaliação. Após analise e discussão reflexiva, consideramos que o cerne da inclusão é a prática instituída no cotidiano da escola e, pensamos que a relevância desta pesquisa está na possibilidade de contribuir com aqueles setores que pretendem instituir a inclusão.
Abstract: Professional experience and difficulties faced in the routine of current work, concerning children with some kind of diagnostic to be included in the regular school, encouraged us to accomplish the present work.

The subjects were all professionals and teachers from this school, students from the last grade of elementary school and from the first and last grade of middle school, parents and one professional from Bom Conselho school, which admits students from CIC. The collected data were related to the following focus of analysis: 1. The school as unity provider; 2. The school as autonomy provider; 3. Connections between parents and school; 4. The school as dialogue provider in the society; 5. The group work; 6. Hearing as ethics exercise; 7. The interdisciplinary team as support and 8. Evaluation practice. After the analysis and discussion, we have considered the practice instituted in the school routine the key for the inclusion. We think that the relevance of this study is in the possibility of contributing to those sectors which intend to institute the inclusion.

Resumo: O presente trabalho tem por objetivo a modelagem estatística da produção de biogás, utilizando-se de modelos de regressão não-linear, a partir do estudo da biodigestão anaeróbia de três tipos de camas de frangos de corte (napier, mistura de napier+maravalha e maravalha), obtidos após um ciclo de criação e após reutilização em um segundo ciclo. Para cada ciclo, foram obtidos dados relativos às produções médias de biogás, apresentados sob forma de totais semanais, em m3 e em valores acumulados para cada substrato. Foi feita a modelagem estatística, a partir dos tratamento definidos, utilizando-se do modelo Gompertz de regressão não-linear, segundo duas linhas metodológicas distintas. Inicialmente, foram considerados modelos de regressão não-linear somente com um componente determinístico e, posteriormente, com dois componentes (mistura). Foram estudadas as propriedades amostrais dos estimadores através de simulações sob a ótica distribucional. A aproximação de uma Gompertz do modelo estatístico proposto para o volume de biogás para os três tipos de camas de frangos mostrou-se adequada em todas situações experimentais, permitindo estimar os parâmetros envolvidos no modelo, utilizando-se técnicas não-paramétricas. O modelo com mistura de duas Gompertz proporcionou bom ajuste aos dados, mas com dificuldades de convergência no processo de estimação dos parâmetros, no qual ocorreu a heterocedasticidade dos erros, isto é, a parte aleatória do modelo não teve variância constante.
Abstract: In this work, the Gompertz model was used to fit the biogas production in batch biodigestor obtained from the anaerobic digestion of three poultry litter kinds (elephant grass, elephant grass + wood shavings and wood shavings). Two strategies of modeling was proposed, i.e., using one and two (mixture) deterministic components in the statistical models. Results showed that Gompertz model with just a deterministic component fits very well, and allowed to compare the estimated parameters among the poultry litter kinds by nonparametric techniques . Although the models with the mixture fits better than the other one, there are some problems with the convergence processes and the parameter estimation.

Pełny tekst źródłaCerebral ischemia is a major cause of death worldwide is caused by a transient or permanent interruption of blood flow and can lead to massive neuronal death. One of neurotoxic events related to ischemia is the excessive increase in the extracellular concentration of glutamate, which leads to hyperstimulation of the glutamatergic system (excitotoxicity) thus triggering a cascade of intracellular events culminating in neurons death. In recent years, the guanosine nucleoside has claimed researchers attention because of its potential neuroprotective effect against insults involving excitotoxicity. In most in vivo experiments in which guanosine presented neuroprotective effects, it was administered systemically, resulting in considerable variability in the magnitude of their effects. Since guanosine is an endogenous molecule being rapidly metabolized systemically before to reach the brain, new routes of administration should be explored in order to maximize their neuroprotective effects. The intranasal route has proven to be an excellent alternative because the good perfusion of the nasal mucosa provides a great via for a quick absorption for drug transport to the brain via cerebrospinal fluid (CSF). In this sense, this thesis evaluated the pharmacokinetic profile of intranasal administration of guanosine and its potential neuroprotective in a model of cerebral ischemia in parietal cortex by thermocoagulation in rats. Thus, we investigated the concentration of guanosine and its metabolites in different brain structures, as well as CSF and plasma after administration of different doses, injection volumes and times after intranasal injection of guanosine by HPLC methods and quantification of radioactivity. There were significant differences in the concentration of purines present in the analyzed structures (cerebral bulb, cortex and hippocampus) plus CSF and plasma. We observed proportionality between the significant increase of radioactivity in relation to the increased concentration and volume. Furthermore, we analyzed these parameters in the plasma and CSF of rats which received intranasally or intraperitoneally injection of guanosine and with those that did not receive it, showing significant differences between these groups. The ischemic induction caused sensorimotor deficit and brain injury, which were reversed by guanosine treatment. Moreover, significant differences in the concentration of purines were observed in plasma and CSF of the animals which can be related with both the ischemic damage as well as with the neuroprotective effect of guanosine. In conclusion, this work is the pioneer showing the viability of intranasal administration of guanosine, in addition to reinforcing the potential neuroprotective effect of guanosine.

LiDAR (an acronym for Light Detection and Ranging) is a technology that can be used to measure properties of the atmosphere. It is similar to radar, but uses much smaller light waves rather than larger radio waves, enabling more detailed information to be obtained. High Spectral Resolution Lidar (HSRL) is a lidar technique that uses a high precision optical filter to distinguish between light that scatters from particulates (such as dust, smoke, or fog) and light that scatters from molecules (such as oxygen, nitrogen, or carbon dioxide) in the atmosphere. By separating the two types of backscattered light, higher accuracy measurements are possible that will enable improvements in climate models, air quality measurements, and climate forecasting. A spaceborne HSRL instrument can provide great impact in these areas by enabling near-continuous measurements across the Earth; however, the optical filter technology has typically been too complex for reliable long-duration spaceflight due to the need for complicated and expensive additional hardware. In this research, a high-performance HSRL optical filter that can be reliably operated by simply monitoring and adjusting the temperature has been designed, built, and tested. The greatly-reduced operational complexity has been made possible through a new process that enables more accurate prediction of the complicated interactions between the materials of the optical filter. This process is based on a combination of high-accuracy characterization of the materials and detailed structural-thermal-optical-performance (STOP) modeling. The overall design process, fabrication procedures, and characterization of the optical filter are presented.

During the early stages of an outbreak of disease, simple interventions such as isolating those infected may be sufficient to prevent further cases. However, should this opportunity be missed, substantially more complex interventions such as the development of novel pharmaceuticals may be required. This results in a differential value for specific knowledge across the early, middle, and late stages of epidemic. Within this dissertation we explore these differentials via extension of the business concept of the time-value of knowledge, whereby key findings may yield greater benefits during early epidemics. We propose the C4 Response Model for organizing research regarding this time-value. First, we define the C4 Response Model as a progression from an initial knowledge collection stage, iteration between knowledge connection stages and machine learning-centric calibration stages, and a final conveyance stage. Secondly we analyze the trends in knowledge-building across the stages of epidemics with regard to open and closed access scientific article publication, referencing, and citation. Thirdly, we demonstrate a Twitter application for improving public health messaging campaigns by identifying optimal combinations of source-profile categories, message categories, timing, urban origination, tone, and use of bots. Finally, we apply an agent-based model of influenza transmission to explore the efficacy of combined antiviral, isolation, and vaccination interventions in mitigating an outbreak of an influenza-like-illness (ILI) within a simulated military base population. We find that while closed access outbreak response articles use more recent citations and see higher mean citation counts, open access articles are growing in use and are published and referenced in significantly greater numbers. We observe that tweet viralities showed distinct benefits to certain message and profile type pairings, that tweets faded rapidly across time and space, and that tweets published before high-tweet-volume time periods are retweeted more. Finally, we saw that while early responses and strong pharmaceuticals showed the greatest impact in preventing influenza transmission within military base populations, even optimistic scenarios failed to prevent the majority to new cases. This body of work offers significant methodological contributions for the practice of computational epidemiology as well as a theoretical grounding for the C4 Response Model.

Resumo: Esta pesquisa trata da Formação Inicial de Professores de Matemática, em particular sobre o uso de tecnologia informática. Sabendo da problemática existente nos cursos de graduação, como, por exemplo, a desarticulação entre teoria e prática, entre formação universitária e realidade escolar, deteve-se na seguinte questão: "Quais são as perspectivas, expectativas e dificuldades que os futuros professores apresentam quando refletem sobre uma prática educativa utilizando planilhas eletrônicas na escola básica?". A pesquisa contou com a participação de dois futuros professores de Matemática da UNESP de Rio Claro. Foram realizados três encontros de planejamento, dez encontros de intervenção em uma escola pública, e dez encontros de reflexão, que ocorreram sempre após cada intervenção. Os licenciandos tiveram a oportunidade de expor suas idéias sobre as experiências realizadas e, a partir de uma análise à luz do referencial teórico, foram extraindo temas que se referem às suas expectativas, perspectivas e dificuldades. Entre eles, a gestão da sala de aula e a transposição de conteúdo, a complexidade da sala de aula, como eles percebem os alunos, as condições de trabalho na escola, ser professor e o uso de tecnologia informática.
Abstract: This research addresses the pre-service mathematics teacher education, in particular their practice with computer. Considering the problems concerning teacher education courses - as, for instance, the disarticulation between the theory and the practice, and between the university education and the school reality - it was formulated the following research question: "What are the perspectives, expectations and difficulties that the future teachers experience when they reflect on an educational practice using spreadsheets at the basic school?" The research was developed in collaboration with two future mathematics teachers from UNESP at Rio Claro, São Paulo, Brazil. It was organized three planning meetings, ten intervention meetings in a public school, and ten reflection meeting, that always took place right after each intervention meeting. The reflection meetings were videoed and transcribed. The data were analyzed with reference to the literature. Themes were identified that could be referred to their expectation, perspectives, and difficulties. These themes included: the teaching in the classroom and the transposition of the contents; the complexity of the classroom environment; the interaction with the students; the school working conditions; being a teacher; and the use of computers.

Pełny tekst źródłaThe doctoral thesis consists of eight chapters. The first chapter contains an overview of the theories on the structures are more typical of polioxometalat and the general characteristics of these complexes. The second chapter presents the computational methods that are based on extensive research and theory that is based on the methodologies used. The first results (Chapter 3) iare presented on a previous study comparing different computational methods with the smallest structures that exist as polyoxoanions, the Lindqvist anions, M6O19n-. The second results chapter (Chapter 4), has reproduced the spectrum of electronic polioxometalat containing a paramagnetic metal in Anderson structures, XM6O24, using various computational methods. In the fifth chapter is the study conducted semiquantitative electrochemical properties of the sandwich type polyoxometalats with more than a paramagnetic metal in its structure, in which the reduction occurs selectively. Verified the position where the first reduction in this anion, as well as the fundamental species of oxidized and reduced. Could play with relative accuracy the electrochemical presented and how these anions in the pH of the reduction process. The sixth chapter is the largest, have been studied extensively the properties of a POM when it contains an atom of Tc. First is a comprehensive discussion of the structures Lindqvist, M6O19, which is taken as a model to be expanded later with the structures of Wells-Dawson. These are ideal candidates for the immobilization of ion Tc (99Tc) that occurs as a radioactive waste at nuclear power plants. Then, the study has been extended to transition metal of groups 6-9 where there has been a general trend in the redox properties and the basicity that produce the substituted metal. After seeing how altering the redox properties of metal knobs monosubstituted transition from groups 6-9, have gone to study the electronic and electrochemical of Keggin anions, {MN}W11O39n- and we have compared with the corresponding oxo complex, {MO}W11O39n-. In the final chapter presents the conclusions drawn from work done throughout this thesis.

In this thesis, I designed a system for augmenting a space with linked audio. Using this system, individuals can associate audio clips with a location in real-world space. When an individual using the system passes through this augmented space, he or she can hear the audio clips that have been left by traveling through the associated locations. Furthermore, audio clips in the environment can be linked together, so that an individual listening to one audio clip can be directed to related audio clips in the augmented space. In addition, a method of allowing the user to navigate through the augmented space is presented.

Pełny tekst źródłaDomestic cats (Felis catus) are abundant generalist predators that exploit a wide range of prey within and adjacent to the urban matrix. Cats are known to have contributed to the extinction and endangerment (mostly on islands) of a number of indigenous species, including birds, small mammals, reptiles and amphibians. Most research on this important topic has been carried out in the developed world, predominantly in Australia, New Zealand, the U.K., the U.S. and Canada with only four studies carried out in Africa. Of these, two studies in Cape Town suggest that domestic cats have a big impact on wildlife but these studies may have underestimated predation because they failed to account for the proportion of prey not returned to participants’ homes. In this study I used kitty-cams in an attempt to provide a prey correction factor for urban cats in Cape Town, South Africa. I investigated hunting of wildlife by free-ranging domestic cats in Newlands, a suburb of Cape Town, South Africa over 5 weeks in 2013. I monitored 13 cats (6 deep-urban and 7 urban-edge) by questionnaire survey, asking cat owners to record all prey items returned by their cats. A total of 43 prey items were returned, 42% of which were small mammals, 30% invertebrates, 12% reptiles, 9% amphibians and 7% birds. Combining these data with two similar survey studies carried out in Cape Town I estimated that a total of 118 cats caught an average of 0.04 prey items per cat per day. Ten of the 13 cats were also monitored for 3 weeks using kitty-cam video cameras. Participating cats wore a video camera and all activity was analysed for prey captures and behavioural activity patterns.

Pełny tekst źródłaIntroduction: In the aging population, depression is among the most frequent chronic diseases. Affect the functionality of the elderly and is considered a serious public health problem. It is a fact that depressive symptoms show up in greater numbers in the institutionalized elderly than in the community due to changes related to family disengagement and adaptation to new customs. Objective: To identify the prevalence of depression in elderly residents in large government and non-government long-stay institutions for the elderly (LTCF) in the city of Fortaleza. Methodology: Quantitative research, cross, drawn through a semi-structured questionnaire. Discusses data sociodemographic, clinical and diagnostic criteria of DSM-IV - TR. The research consisted of all elderly residents in two large nursing homes in Fortaleza. Data were statistically analyzed using SPSS version 20.0 Software. Results: In both institutions prevailed: women, unmarried, illiterate, aged between 70 and 79 years. Of the 237 patients evaluated, 82 (34.6%) had major depression. In the diagnosis of major depression by LTCF, statistical significance was detected when applying the inference test, chi-square, among elderly patients with this pathology in both LTCF (25.6% versus 39% in LTCF governmental and non-governmental respectively) (p = 0.042). Statistical significance was observed between the subject and type of nursing home institutionalization, 24 elderly (29.3%) were institutionalized willingly in LTCF nongovernmental, while 9 (11%) reached the governmental ILPI abandoned by their families (p = 0.001). On family visits, 40 (48.8%) received them in LTCF nongovernmental, while only 9 (6.1%) of depressed elderly had contact with their relatives in government LTCF (p = 0.002). Conclusion: It is considered high the prevalence rate of major depression found in the elderly research, resembling what other studies have found about depressive symptoms in institutionalized elderly. The elderly in the nongovernmental LTCF have become more vulnerable to depression, which is necessary to carry out more in-depth study. The DSM-IV-TR was effective as screening tools for depressive symptoms, however it is important to compare it with the geriatric depression scale of Yesavage, being easy to use and widely used in our environment.
Introdução: Na população envelhecida, a depressão encontra-se entre as doenças crônicas mais frequentes. Prejudica a funcionalidade do idoso e é considerada como um problema grave de saúde pública. É fato que sintomas depressivos se apresentam em maior número nos idosos institucionalizados do que na comunidade, em consequência das mudanças relacionadas à desvinculação familiar e adaptação a novos costumes. Objetivo: Identificar a prevalência de depressão em residentes em instituições de longa permanência de idosos (ILPI) de grande porte governamental e não governamental no Município de Fortaleza. Metodologia: Pesquisa quantitativa, transversal, elaborada por meio de um questionário semiestruturado. Aborda dados sociodemográficos, clínicos e os critérios de diagnóstico do DSM-IV - TR. O universo da pesquisa constituiu-se de todos os idosos residentes nas duas ILPI de grande porte do Município de Fortaleza. Os dados foram analisados estatisticamente, por meio do software SPSS versão 20.0 (SPSS Inc, Chicago, IL, USA). Resultado:. Em ambas as instituições prevaleceram: mulheres, solteiros, não alfabetizados, faixa etária entre 70 e 79 anos. Dos 237 pacientes avaliados, 82 (34,6%) apresentaram depressão maior. No diagnóstico de depressão maior por ILPI, detectou-se significância estatística, ao se aplicar o teste de inferência, quiquadrado, entre os idosos acometidos por esta patologia (25,6% versus 39% nas ILPI governamental e não governamental respectivamente) (p=0,042); entre motivo da institucionalização e tipo de ILPI, 24 idosos (29,3%) institucionalizaram-se por vontade própria na ILPI não governamental, enquanto 9 (11%) chegaram à ILPI governamental abandonados por suas famílias (p=0,001). Relativamente à visita de familiares, 40 (48,8%) recebiam-nas na ILPI não governamental, enquanto apenas 9 (6,1%) dos idosos deprimidos tinham contato com seus parentes na ILPI governamental (p=0,002). Conclusão: Considera-se alta a taxa de prevalência de depressão maior detectada nos idosos da pesquisa, assemelhando-se à de outros estudos que constataram sintomas depressivos em idosos institucionalizados. Os idosos da ILPI não governamental mostram-se mais fragilizados à depressão, fazendo-se necessário realizar estudos mais aprofundados. O DSM-IV- TR mostrou-se eficaz como instrumento de rastreio de sintomas depressivos, contudo seria importante compará-lo com a escala de depressão geriátrica de Yesavage, por ser de fácil aplicação e bastante utilizada em meio local.

Pełny tekst źródłaEsta dissertação trata de uma problemática nova que aparece em um dos cursos recentemente publicado na Gesamtausgabe de Martin Heidegger, que é a lição de inverno de 1928/29 intitulada Introdução à Filosofia . O nosso objetivo consiste em analisar e reconstruir o conceito de jogo que se apresenta como a forma de determinação conceitual da transcendência. Esse conceito não apenas se relaciona à transcendência, senão também à compreensão de ser, que é considerada um momento essencial da transcendência. Então, além da noção de jogo e de transcendência, será caracterizada a noção de compreensão de ser. Como resultado temos a constatação de que a transcendência é a condição de possibilidade da compreensão de ser. Além disso, ela é a formação de sentidos de ser, sentidos que tanto se manifestam como se ocultam historicamente.
