Olhares acerca do processo de construção dos Projetos Políticos Pedagógicos dos cursos Técnicos Integrados ao Ensino Médio de Jovens e Adultos no contexto do Ifes campus Vitória

Este trabalho é resultado da investigação que teve como objetivo analisar o processo de construção dos Projetos Políticos Pedagógicos dos cursos do Proeja no contexto do Ifes campus Vitória. O problema de pesquisa buscou captar os movimentos e as experiências desencadeados nesse processo. No percurso metodológico, com ênfase na pesquisa qualitativa, foi necessário entrelaçar duas abordagens: a etnografia escolar e a pesquisa-ação em função da atuação profissional da pesquisadora no lócus de estudo. Variados instrumentos foram utilizados para levantamento e a produção dos dados, dentre os quais: questionários, entrevistas, diário de campo das observações, pesquisa bibliográfica e documental. Participaram da pesquisa aproximadamente 80 pessoas, entre docentes, alunos e gestores, abordados em contextos específicos: o grupo de formação continuada, a comissão dos projetos, o encontros dos alunos, a reunião intermediária dentre outros. O referencial teórico-metodológico pautado na perspectiva do materialismo histórico dialético embasou toda a trajetória investigativa, em coerência com a base da produção das pesquisas sobre trabalho e educação e por se constituir a referência que fundamenta os princípios estruturantes do currículo integrado na perspectiva da formação humana. Por meio da metáfora dos observatórios, focamos nossas lentes sobre as questões que desafiaram a construção dos projetos políticos pedagógicos e sua coerência com os princípios epistemológicos, políticos e pedagógicos do Proeja. Nesse movimento, diversos olhares foram captados, possibilitando-nos levantar os seguintes resultados: o percurso de construção dos projetos foi marcado por contradições que perpassam todo o processo e que constituíram um debate profícuo que tenciona a gestão pedagógica, administrativa e financeira do Ifes campus Vitória. O movimento se constituiu também em um processo de construção, partilha de saberes e experiências, impulsionado pela busca da apreensão dos sentidos da integração, que contraditoriamente não alcançou seus objetivos, embora não se possa negar os resultados positivos do processo no interior da Instituição. Dessa forma, os desafios para efetivação da formação integrada no Ifes persistem. Ganha centralidade nessa discussão os sujeitos a quem o programa se volta e suas demandas de formação, bem como as condições materiais de oferta dos cursos e de forma especial as condições de envolvimento dos professores com o programa e as reflexões sobre suas práticas.

A economia da informação : rumo a um programa de pesquisa alternativo

Este trabalho tem por objetivo discutir o surgimento de um programa de pesquisa na Ciência Econômica, no que concerne a análise das assimetrias de informação, as diferenças epistemológicas e as implicações em termos de equilíbrio ótimo de Pareto, em contraponto à abordagem neoclássica standard. Em busca de tal objetivo, foi necessário destacar o método de ambos os paradigmas; todavia, era igualmente necessário discutir a filosofia/epistemologia da ciência envolvida e que serviria de base para uma abordagem relacionada a mudanças paradigmáticas na ciência. No capítulo 1, discutimos a epistemologia da ciência, a partir de três autores: Popper, Kuhn e Lakatos. Definimos o conjunto de hipóteses que podem ser associadas ao método empregado pela Escola Neoclássica, a partir da filosofia da ciência proposta por Lakatos. Em seguida, no capítulo 2, fizemos uma longa exposição do método neoclássico, definindo os axiomas inerentes às preferências bem-comportadas, apresentando algebricamente o equilíbrio geral walrasiano, exemplificando o relaxamento de hipóteses auxiliares do modelo neoclássico a partir de Friedman e, por fim, aplicando o instrumental neoclássico ao relaxamento da hipótese auxiliar de perfeição da informação, a partir do modelo desenvolvido por Grossman & Stiglitz (1976), bem como da expansão matemática desenvolvida pelo presente trabalho. Finalmente, encerramos a presente dissertação com o capítulo 3, no qual, basicamente, expomos as principais contribuições de autores como Stiglitz, Akerlof e Arrow, no que concerne a mercados permeados por informações assimétricas e comportamentos oportunistas. Procuramos mostrar as consequências para o próprio mercado, chegando a resultados em que o mesmo era extinto. Apresentamos a segunda parte do modelo de Grossman & Stiglitz, enfatizando a natureza imperfeita do sistema de preços, sua incapacidade de transmitir todas as informações sobre os bens ao conjunto dos agentes, e, por fim, discutimos tópicos variados ligados à Economia da Informação.

The portuguese insurance industry: basis for strategic process decision

Nowadays, the Portuguese insurance industry operates in a market with a much more aggressive structure than a few decades ago. Markets and the economy have become globalised since the last decade of the 20th century. Market forces have gradually shifted – power is now mainly on the demand side. In order to meet the new requirements, the insurance industry must develop a strong strategic ability to respond to constant changes of the new international economic order.One of the basic aspects of this strategic development will focus on the ability to predict the future. We introduce the subject by briefly describing the sector, its organisational structure in the Portuguese market, and challenges arising from the development of the European Union. We then analyse the economic and financial structure of the sector. From this point of view, we aim at the possibility of designing models that could explain the demand for insurance, claims and technical reserves evolution. Such models, (even if based on the past), would resolve, at least partly, one of the greatest difficulties experienced by insurance companies when estimating the budget. Thus, we examine the existence of variables that explain the previous points, which are capable of forming a basis for designing models that are simple but efficient, and can be used for strategic planning.

Basis invariant conditions for supersymmetry in the two-Higgs-doublet model

The minimal supersymmetric standard model involves a rather restrictive Higgs potential with two Higgs fields. Recently, the full set of classes of symmetries allowed in the most general two-Higgs-doublet model was identified; these classes do not include the supersymmetric limit as a particular class. Thus, a physically meaningful definition of the supersymmetric limit must involve the interaction of the Higgs sector with other sectors of the theory. Here we show how one can construct basis invariant probes of supersymmetry involving both the Higgs sector and the gaugino-Higgsino-Higgs interactions.

Texture zeros and weak basis transformations

We investigate the physical meaning of some of the "texture zeros" which appear in most of the Ansatze on quark masses and mixings. It is shown that starting from arbitrary quark mass matrices and making a suitable weak basis transformation one can obtain some of these sets of zeros which therefore have no physical content. We then analyse the physical implications of a four-texture zero Ansatz which is in agreement with all present experimental data. (C) 2000 Elsevier Science B.V. AU rights reserved.

Node adaptation for global collocation with radial basis functions using direct multisearch for multiobjective optimization

Meshless methods are used for their capability of producing excellent solutions without requiring a mesh, avoiding mesh related problems encountered in other numerical methods, such as finite elements. However, node placement is still an open question, specially in strong form collocation meshless methods. The number of used nodes can have a big influence on matrix size and therefore produce ill-conditioned matrices. In order to optimize node position and number, a direct multisearch technique for multiobjective optimization is used to optimize node distribution in the global collocation method using radial basis functions. The optimization method is applied to the bending of isotropic simply supported plates. Using as a starting condition a uniformly distributed grid, results show that the method is capable of reducing the number of nodes in the grid without compromising the accuracy of the solution.

Reliability and availability in reconfigurable computing: a basis for a common solution

Dynamically reconfigurable SRAM-based field-programmable gate arrays (FPGAs) enable the implementation of reconfigurable computing systems where several applications may be run simultaneously, sharing the available resources according to their own immediate functional requirements. To exclude malfunctioning due to faulty elements, the reliability of all FPGA resources must be guaranteed. Since resource allocation takes place asynchronously, an online structural test scheme is the only way of ensuring reliable system operation. On the other hand, this test scheme should not disturb the operation of the circuit, otherwise availability would be compromised. System performance is also influenced by the efficiency of the management strategies that must be able to dynamically allocate enough resources when requested by each application. As those resources are allocated and later released, many small free resource blocks are created, which are left unused due to performance and routing restrictions. To avoid wasting logic resources, the FPGA logic space must be defragmented regularly. This paper presents a non-intrusive active replication procedure that supports the proposed test methodology and the implementation of defragmentation strategies, assuring both the availability of resources and their perfect working condition, without disturbing system operation.

Slaughterhouses fungal burden assessment: a contribution for the pursuit of a better assessment strategy

In slaughterhouses, the biological risk is present not only from the direct or indirect contact with animal matter, but also from the exposure to bioaerosols. Fungal contamination was already reported from the floors and walls of slaughterhouses. This study intends to assess fungal contamination by cultural and molecular methods in poultry, swine/bovine and large animal slaughterhouses. Air samples were collected through an impaction method, while surface samples were collected by the swabbing method and subjected to further macro- and micro-scopic observations. In addition, we collected air samples using the impinger method in order to perform real-time quantitative PCR (qPCR) amplification of genes from specific fungal species, namely A. flavus, A. fumigatus and A. ochraceus complexes. Poultry and swine/bovine slaughterhouses presented each two sampling sites that surpass the guideline of 150 CFU/m3. Scopulariopsis candida was the most frequently isolated (59.5%) in poultry slaughterhouse air; Cladosporium sp. (45.7%) in the swine/bovine slaughterhouse; and Penicillium sp. (80.8%) in the large animal slaughterhouse. Molecular tools successfully amplified DNA from the A. fumigatus complex in six sampling sites where the presence of this fungal species was not identified by conventional methods. This study besides suggesting the indicators that are representative of harmful fungal contamination, also indicates a strategy as a protocol to ensure a proper characterization of fungal occupational exposure.

Natural and amyloid self-assembly of S100 proteins: structural basis of functional diversity

The S100 proteins are 10-12 kDa EF-hand proteins that act as central regulators in a multitude of cellular processes including cell survival, proliferation, differentiation and motility. Consequently, many S100 proteins are implicated and display marked changes in their expression levels in many types of cancer, neurodegenerative disorders, inflammatory and autoimmune diseases. The structure and function of S100 proteins are modulated by metal ions via Ca2+ binding through EF-hand motifs and binding of Zn2+ and Cu2+ at additional sites, usually at the homodimer interfaces. Ca2+ binding modulates S100 conformational opening and thus promotes and affects the interaction with p53, the receptor for advanced glycation endproducts and Toll-like receptor 4, among many others. Structural plasticity also occurs at the quaternary level, where several S100 proteins self-assemble into multiple oligomeric states, many being functionally relevant. Recently, we have found that the S100A8/A9 proteins are involved in amyloidogenic processes in corpora amylacea of prostate cancer patients, and undergo metal-mediated amyloid oligomerization and fibrillation in vitro. Here we review the unique chemical and structural properties of S100 proteins that underlie the conformational changes resulting in their oligomerization upon metal ion binding and ultimately in functional control. The possibility that S100 proteins have intrinsic amyloid-forming capacity is also addressed, as well as the hypothesis that amyloid self-assemblies may, under particular physiological conditions, affect the S100 functions within the cellular milieu.
