La matriz de insumo-producto de América del Sur: principales supuestos y consideraciones metodológicas

Esta nota ha sido preparada como resultado del proyecto conjunto de la Comisión Económica para América latina y el Caribe (CEPAL) y el Instituto de Pesquisa Econômica Aplicada (IPEA) del Brasil para la elaboración de una matriz de insumo-producto interconectada para los países de América del Sur, instrumento que a su vez será de utilidad para el análisis de cadenas de valor en esa región.

A Matriz Filosófica do Presbiterianismo no Brasil

Os missionários protestantes presbiterianos que vieram para o Brasil no início da segunda metade do século XIX trouxeram uma interpretação calvinista da bíblia, pois permaneceram fieis à formação princetoniana que efetivou uma síntese entre ortodoxia calvinista e pietismo. Estes pricetonianos tinham como base epistemológica a filosofia de Thomas Reid, conhecida como o Realismo do Senso Comum. Essa filosofia é utilizada como uma epistemologia reformada, ou calvinista. Ela é compreendida em sua formação escocesa e consequentemente americana, via Princeton, como a Epistemologia Providencial. Desta forma, quando ela é assimilada pelos brasileiros por meio da pregação e da formação teológica, a mesma se torna parte do perfil presbiteriano brasileiro como doutrina filosófica. A Filosofia do Senso Comum se gesta como crítica à filosofia empirista de David Hume que, para Reid, convergiria para um possível aniquilamento da religião e para uma visão pessimista da ciência, afetando o empirismo, por conseguinte, causando uma nova formulação mais próxima do ceticismo. Por isso, Reid formulou a filosofia que para ele contrapõe-se a Locke e Berkeley e depois a David Hume, afirmando que a realidade é independente de nossa apreensão. Ou seja, na percepção do mundo exterior não há interferência do sujeito cognoscente sobre o objeto do conhecimento. A nossa relação com os objetos é direta e não deve ser desvirtuada por intermediações. Na implantação do protestantismo no Brasil, via missionários de Princeton, não houve uma defesa intransigente dos princípios calvinistas por parte de missionários como Fletcher e Simonton e sim uma continuidade da leitura das escrituras sagradas pelo viés calvinista, como era feito no Seminário de Princeton. Não havia uma ênfase acentuada na defesa da ortodoxia porque o tema do liberalismo teológico, ou do conflito entre modernismo e fundamentalismo não se fazia necessário na conjuntura local, onde predominava a preocupação pela evangelização em termos práticos. O conceitos da Filosofia do Senso Comum eram próximos do empirismo mitigado de Silvestre Pinheiro e do Ecletismo de Victor Cousin. Por isso, no Brasil, o local em que mais se vê a utilização da filosofia do Senso Comum é nos debates entre intelectuais, em três pontos interessantes: 1ª) O Senso Comum ficou restrito ao espaço acadêmico, na formação de novos pastores, sendo que as obras de Charles Hodge e A. A. Hodge são as principais fontes de implantação desta mentalidade ratificadora da experiência religiosa e, desta forma, delineiam o rosto do protestantismo entre presbiterianos, uma das principais denominações protestantes do final do século XIX; 2ª) Nos debates entre clérigos católicos e protestantes em polêmicas teológicas;. 3º) No aproveitamento utilitarista da assimilação cultural estrangeira pelos protestantes nacionais, não por último, facilitada pela simpatia dos liberais brasileiros pelo protestantismo, ao mesmo tempo que mantinham uma linha filosófica mais próxima do empirismo mitigado e do ecletismo. Assim, nossa hipótese pretende demonstrar que os protestantes trouxeram em seu bojo as formulações epistemológicas que foram passadas para um grupo de intelectuais, que formaram o quadro dos primeiros pastores presbiterianos da história desta denominação. Eles foram convertidos e assimilaram melhor as novas doutrinas por meio de mais do que simples pregações, mas pela sua forma filosófica de encarar os objetos estudados, e que tais informações vêm por meio da base epistemológica do Realismo do Senso Comum, que encontra espaço nos ideais republicanos brasileiros do século XIX.

Frei Caneca: matriz do jornalismo brasileiro

Analisar a retórica construída por Frei Caneca e reconstruir seu pensamento comunicacional, argumentando que a atividade desenvolvida na imprensa o credencia como matriz do jornalismo brasileiro, constituem os objetivos desta pesquisa. Trata-se de estudo exploratório, apoiado em fontes bibliográficas e documentais, com a intenção de compreender o contexto histórico da retórica e do jornalismo brasileiro na época. Para caracterizar o jornalismo praticado por Frei Caneca foi aplicado o método misto quantitativo e qualitativo da análise de conteúdo. Os resultados indicaram que Frei Caneca, por meio da retórica, iniciou a produção de um jornalismo argumentativo estruturado, pois seus textos tinham base teórica. Desta maneira, contribuiu para o avanço dos estudos de Teoria do Jornalismo ao fazer uma leitura brasileira da retórica e da eloquência.

Sobre a integração indefinida de funções racionais complexas: teoria e implementação de algoritmos racionais

We present indefinite integration algorithms for rational functions over subfields of the complex numbers, through an algebraic approach. We study the local algorithm of Bernoulli and rational algorithms for the class of functions in concern, namely, the algorithms of Hermite; Horowitz-Ostrogradsky; Rothstein-Trager and Lazard-Rioboo-Trager. We also study the algorithm of Rioboo for conversion of logarithms involving complex extensions into real arctangent functions, when these logarithms arise from the integration of rational functions with real coefficients. We conclude presenting pseudocodes and codes for implementation in the software Maxima concerning the algorithms studied in this work, as well as to algorithms for polynomial gcd computation; partial fraction decomposition; squarefree factorization; subresultant computation, among other side algorithms for the work. We also present the algorithm of Zeilberger-Almkvist for integration of hyperexpontential functions, as well as its pseudocode and code for Maxima. As an alternative for the algorithms of Rothstein-Trager and Lazard-Rioboo-Trager, we yet present a code for Benoulli’s algorithm for square-free denominators; and another for Czichowski’s algorithm, although this one is not studied in detail in the present work, due to the theoretical basis necessary to understand it, which is beyond this work’s scope. Several examples are provided in order to illustrate the working of the integration algorithms in this text

Gráfico de controle modificado para processos com estruturas complexas de autocorrelação

This work proposes a modified control chart incorporating concepts of time series analysis. Specifically, we considerer Gaussian mixed transition distribution (GMTD) models. The GMTD models are a more general class than the autorregressive (AR) family, in the sense that the autocorrelated processes may present flat stretches, bursts or outliers. In this scenario traditional Shewhart charts are no longer appropriate tools to monitoring such processes. Therefore, Vasilopoulos and Stamboulis (1978) proposed a modified version of those charts, considering proper control limits based on autocorrelated processes. In order to evaluate the efficiency of the proposed technique a comparison with a traditional Shewhart chart (which ignores the autocorrelation structure of the process), a AR(1) Shewhart control chart and a GMTD Shewhart control chart was made. An analytical expression for the process variance, as well as control limits were developed for a particular GMTD model. The ARL was used as a criteria to measure the efficiency of control charts. The comparison was made based on a series generated according to a GMTD model. The results point to the direction that the modified Shewhart GMTD charts have a better performance than the AR(1) Shewhart and the traditional Shewhart.

He was obtained and studied the feasibility of using TPA (Tissue Cotton Plan) screen type, for bagging, with a weight of 207.9 g / m2 in a composite of orthophthalic crystal polyester resin matrix. The process for obtaining the composite was tested against the maximum number of layers that could be used without compromising the processability and manufacturing of CPs in compression mold. Five configurations / formulations were selected and tested at 1, 4, 8, 10 and 12 layers of cotton tissue - TPA. TPA was not subjected to chemical treatment, only by passing a mechanical washing process. The composite in its various configurations / formulations was characterized to determine its physical properties. The properties of the composite were higher viability resistance to bending, approaching the matrix and impact resistance, superiority in relation to the polyester resin. Another property that has shown good result compared to other composite has water absorption. Analyzing all the properties set the settings / formulations with higher viability were TA8 and TA10, by combining good processability and higher mechanical strength, with lower loss compared to polyester resin matrix. The composite showed lower mechanical behavior of the resin matrix for all the formulations studied except the impact resistance. The SEM showed a good adhesion between the layers of TPA and polyester resin matrix, without the presence of micro voids in the matrix confirming the efficient manufacturing process of the samples for characterization. The composite proposed proved to be viable for the fabrication of structures with low requests from mechanical stresses, and as demonstrated for the manufacture of solar and wind prototypes, and packaging, shelving, decorative items, crafts and shelves, with good visual appearance.

Plasticidade dependente da experiência induzida por manipulação da matriz extracelular

The primary somatosensory cortex (S1) receives inputs from peripheral tactile receptors and plays a crucial role on many important behaviors. However, the plastic potential of this region is greatly reduced during adulthood, limiting functional recovery after injuries. This fact is due to the presence, in the brain parenchima, of structures and substances that have an inhibitory effect on plasticity, such as chondroitin sulfate proteoglicans (CSP) present in the perineuronal.nets (PNNs) surrounding a subset of neurons. Maturation of PNNs coincide with the closure of critical periods of plasticity in cortical areas, since CSP act to stabilize synaptic contacts. Removal of CSP is proven to be an effective therapeutic approach to restore plasticity and increase the odds of functional recovery after cortical lesion. In the present work, we removed CSP from the sensorimotor cortex of rats to restore plasticity and promote the compensatory morphofunctional regeneration of cortical circuits modified by removal of mystacial vibrissae during the critical period. Treatment with the CSP-digesting enzyme chondroitinase ABC proved efficient to restore plasticity in S1 circuits, as evidenced by morphological rearrangements and functional recovery.

Obtenção e caracterização de um compósito de matriz polimérica com carga de resíduos vegetal proveniente do sabugo de milho

The feasibility of using the corn cob to obtain a polymer matrix composite was studied. To obtain the bran, corncob passed the drying process in a solar dryer, and was subsequently triturated in forage and to obtain the different particle sizes, by sieving. Three different grain sizes were used: fine particles (FP) size between 0,10 and 2mm; sized particles (PM) with sizes between 2,10 and 3,35 mm; large particles (PG) sizes between 3,45 and 4,10 mm. Using 20% of residue relative to the resin, the test samples were constructed for characterization of the composite, taking into account thermal and mechanical parameters. The main advantage of the proposed composite is that it has a low density, below the relative resin, about 1.06 kg / m³ for the PG. The composite showed a mechanical behavior less than of the resin to the grain sizes and for all formulations studied. Showed better results for the bending, reaching 25.3 MPa for the PG. The composite also showed be feasible for thermal applications, with thermal conductivity less than 0.21 W / m, ranking as insulation. In terms of homogeneity of the mixture, the most viable grain size is the PF, which also showed improved aesthetics and better processability. This composite can be used to make structures that do not require significant mechanical strength, such as tables, chairs, planks, and solar and wind prototypes, such as ovens and cookers and turbines blades.
