Una aproximación al conocimiento experto : Debates locales e internacionales y panorama del campo intelectual de la educación

La indagación sobre el complejo vínculo de los intelectuales con el Estado y su intervención en la esfera pública como portadores de distintos tipos de expertise, transcurre actualmente en un área renovada de estudios conformada en el entrecruce de la historia y la sociología en relación al Estado, a la ciencia y la educación superior, así como a partir de los aportes del análisis de políticas públicas, la sociología de las profesiones y de las elites. Este trabajo pretende explorar algunas dimensiones de los debates locales e internacionales suscitados por el desarrollo de la expertise en ciencias sociales, con el objetivo de interiorizarnos para futuras investigaciones respecto a la participación de expertos en la elaboración de las políticas educativas a partir de la transición democrática en Argentina. Por un lado, consideraremos los debates internacionales sobre la autonomía y la utilidad social de la actividad científica en los estudios sociales de la ciencia, analizando también desde la sociología de las profesiones el lugar del saber técnico y del Estado en la autonomía y el desarrollo profesional. Asimismo contemplaremos las disputas entre profesiones y la constitución de elites técnicas estatales, sus enfrentamientos por el poder y su conexión con la circulación trasnacional de saberes y personas. Por otro lado, exploraremos el rol interpretado por diversos tipos de ideas y en particular por el conocimiento experto en la elaboración de políticas públicas, atendiendo igualmente a las particularidades de la actividad experta, su multiplicidad de recursos y ámbitos de inserción, su compleja relación con la política y el saber profano, así como su influencia en la construcción social de la realidad. Consideraremos, finalmente, las discusiones que en torno a algunos aspectos de esta compleja temática se han desarrollado recientemente en el ámbito local y particularmente en el campo de la producción de conocimiento en educación

Os boêmios cívicos da Assessoria Econômica: saber técnico e decisão política no governo Vargas (1951-54)

Este texto tem como objetivo analisar o papel e a atuação da Assessoria Econômica no segundo governo Vargas a partir de entrevistas que alguns de seus membros concederam ao Centro de Pesquisa e Documentação de História Contemporânea do Brasil (CPDOC), da Fundação Getulio Vargas, ao longo da década de 1980. Ao avaliar a posteriori a curta, porém intensa, experiência que tiveram como “braço imediato” do presidente da República,2 os depoimentos de Rômulo de Almeida, Cleantho Paiva Leite e Ignacio Rangel tornam-se fontes particularmente interessantes para quem está interessado em entender os meandros do processo de industrialização, em particular o papel que nele desempenharam as chamadas “elites técnicas”.

Caminhos que estruturam cidades: redes técnicas de transporte sobre trilhos e a conformação intra-urbana de Natal

The railroad, from 1870 and on, becomes an usual complaining in the press s and politician elite s speeches, especially because of Natal s geographic isolation. The implantation of two railroads in the capital territory Estrada de Ferro de Natal a Nova Cruz, afterwards part of Great Western Railway Company network, and Estrada de Ferro Central do Rio Grande do Norte had serious implications in the urban environment. While railroad s structures were already consolidated, other transportation mechanisms were being implanted in the first decades of the 20th century, such as trams lines, which, by the way, was a transport modal that also used rails as a dislocation meaning. Considering these questions, we may ask: how come railroads and tramways demands, roads and buildings had influenced the internal organization of Natal? We work with the general hypothesis that the influence of technical networks, composed by tramways and railroads, over Natal s urban space happened in a diversified way, sometimes consolidating social aspects in certain areas, sometimes improving the occupation of others. The impact over the city s territory also happens in a diversified way between the buildings/railroad s complexes and the pathways. The different scale of the train in comparison to the trams velocity, size, noise level, flow, among others is also a cause to the different consequences in urban environment. The main objective of this work is to understand the role of circulation technical networks in the construction process of urban space in Natal, as a way to contribute to the urban historiography about the subject. The time frame adopted, between 1881 and 1937, marks the time path of railroads and tramways in Rio Grande do Norte: 1881 is the year of railroad s first section inauguration from Natal to São José do Mipibu as well of the railroad complex in the Republic Square in Natal; the year of 1937 marks the beginning of tramways declination process in the city. At this time railroads and tramways had to face more intensively the competition of motor vehicles. The theory reference adopted is based on concepts and analysis of authors, such as Flávio Villaça and Roberto Lobato Corrêa references to the concepts of urban structure , localization and accessibility and Gabriel Dupuy to explain the concept of urban technical networks . These references reveal the conflict of different realities in the urban universe interests and values which is an important factor about the construction of urban space. The information sources used were from two distinctive natures: primary, journals of the time studied and official government reports, and secondary, based on other works about the subject. It was also used by this study iconographic source, especially images from the data base of the research group História da Cidade, do Território e do Urbanismo .

Empresas públicas : de estatales a privadas (1976-2001)

La relación del Estado con las empresas públicas ha sido oscilante a lo largo de la historia argentina. El objetivo de este trabajo es demostrar esta relación en el período que va desde 1976 hasta 2001. Mientras otros autores ven a este período como de liberalización de la economía, aquí se afirma que las instancias estatales siempre apuntalaron la dinámica de acumulación suscitada por la de las empresas públicas. Independientemente de que el rasgo característico del periodo analizado se destaque por la trasferencia de activos al sector privado, el Estado auspició este proceso favoreciendo la concentración económica.

Polímeros biomiméticos em química analítica. Parte 1: preparo e aplicações de MIP (Molecularly Imprinted Polymers) em técnicas de extração e separação

MIPs are synthetic polymers that are used as biomimetic materials simulating the mechanism verified in natural entities such as antibodies and enzymes. Although MIPs have been successfully used as an outstanding tool for enhancing the selectivity or different analytical approaches, such as separation science and electrochemical and optical sensors, several parameters must be optimized during their synthesis. Therefore, the state-of-the-art of MIP production as well as the different polymerization methods are discussed. The potential selectivity of MIPs in the extraction and separation techniques focusing mainly on environmental, clinical and pharmaceutical samples as applications for analytical purposes is presented.

Chem., Vol. 76, No. 2, 443-451, 2004) from IUPAC© for the Portuguese Language. Additional terms that had not been defined in native Portuguese were included for the benefit of the local community. Additional notes were also included to clarify some important concepts and to highlight the differences between techniques.

Avaliação de técnicas de classificação digital de imagens landsat em diferentes padrões de cobertura da terra em Rondônia

Remotely sensed imagery has been widely used for land use/cover classification thanks to the periodic data acquisition and the widespread use of digital image processing systems offering a wide range of classification algorithms. The aim of this work was to evaluate some of the most commonly used supervised and unsupervised classification algorithms under different landscape patterns found in Rondônia, including (1) areas of mid-size farms, (2) fish-bone settlements and (3) a gradient of forest and Cerrado (Brazilian savannah). Comparison with a reference map based on the kappa statistics resulted in good to superior indicators (best results - K-means: k=0.68; k=0.77; k=0.64 and MaxVer: k=0.71; k=0.89; k=0.70 respectively for three areas mentioned). Results show that choosing a specific algorithm requires to take into account both its capacity to discriminate among various spectral signatures under different landscape patterns as well as a cost/benefit analysis considering the different steps performed by the operator performing a land cover/use map. it is suggested that a more systematic assessment of several options of implementation of a specific project is needed prior to beginning a land use/cover mapping job.

As técnicas NASVD e MNF e sua aplicação na redução de ruídos em dados gamaespectrométricos

A desintegração radioativa é um processo aleatório e a estimativa de todas as medidas associadas é governada por leis estatísticas. Os perfis de taxas de contagem são sempre "ruidosos" quando utilizados períodos curtos como um segundo para cada medida. Os filtros utilizados e posteriormente as correções feitas no processamento atual de dados gamaespectrométricos não são suficientes para remover ou diminuir, consideravelmente, o ruído oriundo do espectro. Dois métodos estatísticos que atuam diretamente nos dados coletados, isto é, nos espectros, vêm sendo sugeridos na literatura para remover e minimizar estes ruídos remanescentes o Noise-Adjusted Singular Value Decomposition - NASVD e Maximum Noise Fraction - MNF. Estes métodos produzem uma redução no ruído de forma significativa. Neste trabalho eles foram implementados dentro do ambiente de processamento do software Oasis Montaj e aplicados na área compreendida pelos blocos I e II do levantamento aerogeofísico que recobre a porção oeste da Província Mineral do Tapajós, entre os Estados do Pará e Amazonas. Os dados filtrados e não-filtrados com as técnicas de NASVD e MNF foram processados com os parâmetros e constantes fornecidos pela empresa Lasa Engenharia e Prospecções S.A., sendo estes comparados. Os resultados da comparação entre perfis e mapas apresentaram-se de forma promissora, pois houve um ganho na resolução dos produtos.

Técnicas de diagnóstico de influência local na análise espacial da produtividade da soja

A modelagem da estrutura de dependência espacial pela abordagem da geoestatística é fundamental para a definição de parâmetros que definem esta estrutura, e que são utilizados na interpolação de valores em locais não amostrados pela técnica de krigagem. Entretanto, a estimação de parâmetros pode ser muito afetada pela presença de observações atípicas nos dados amostrados. O desenvolvimento deste trabalho teve por objetivo utilizar técnicas de diagnóstico de influência local em modelos espaciais lineares gaussianos, utilizados em geoestatística, para avaliar a sensibilidade dos estimadores de máxima verossimilhança e máxima verossimilhança restrita na presença de dados discrepantes. Estudos com dados experimentais mostraram que tanto a presença de valores atípicos como de valores considerados influentes, pela análise de diagnóstico, pode exercer forte influência nos mapas temáticos, alterando, assim, a estrutura de dependência espacial. As aplicações de técnicas de diagnóstico de influência local devem fazer parte de toda análise geoestatística a fim de garantir que as informações contidas nos mapas temáticos tenham maior qualidade e possam ser utilizadas com maior segurança pelo agricultor.
