Avalia??o entre ?pares? na ciência e na academia: aspectos clandestinos de um julgamento nem sempre científico, acadêmico ou ?de avalia??o?
Botomé, Sílvio Paulo;
Psicologia USP , 2011, DOI: 10.1590/S0103-65642011005000013
Abstract: the assessment of academic work cannot be reduced to the measures. but there is an extensive “naturalization” of procedures that are not driven every respect constituting this “evaluation”. one aspect of this “naturalization has been slow and subtle substitution of debate and criticism of academic studies for its simple display, publication or presentation with examination more administrative than academic. the “peer reviews” has been a requirement with problems. they include the anonymity of the appraiser and it allows many “deviations” for an assessment of political, ideological or even personal. the tendency toward hegemony of groups is one of the problems. the recent proliferation of academic societies (or scientific), academic or professional journals, the publication requirements (number of titles) as a criterion for contests, promotions, financial aid or scholarships has increased the bureaucracy to administer it with a possible prejudice to the existing distortions to the development of science.

Psicologia: Ciência e Profiss?o , 2002, DOI: 10.1590/s1414-98932002000100007
Abstract: Observando sess es de estudo de crian as atendidas em agência educacional, foram identificados comportamentos de agentes educativos como “comentar trabalhos realizados”, “identificar situa es para intervir”, “apresentar conseqüências para estudar” e “intervir diante de comportamentos concorrentes ao estudar”, e propriedades desses comportamentos, como freqüência, dura o, latência, forma e distribui o temporal, componentes de contingências relacionadas à aquisi o e manuten o de comportamentos ao estudar. Educational agents behaviors like “commenting on works done”, “identifying when to make an interference”, “presenting consequences to be kept studying” and “making an interference when facing other behaviors than study” were identified by observing supervised studying sessions of children in an educational agency. In that behaviors it was possible to identify, too, many proprieties, like frequency, duration, latency, topography and temporal distribution, which were part of contingencies related to acquisition and maintenance of studying.

Abstract: a major constraint to agricultural production in acid soils of tropical regions is the low soil p availability, due to the high adsorption capacity, low p level in the source material and low efficiency of p uptake and use by most of the modern varieties grown commercially. this study was carried out to evaluate the biomass production and p use by forage grasses on two soils fertilized with two p sources of different solubility. two experiments were carried out, one for each soil (cambisol and latosol), using pots filled with 4 dm3 soil in a completely randomized design and a 4 x 2 factorial scheme. the treatments consisted of a combination of four forage plants (brachiaria decumbens, brachiaria brizantha, pennisetum glaucum and sorghum bicolor) with two p sources (triple superphosphate - tsp and arad reactive phosphate - arp), with four replications. the forage grasses were harvested at pre-flowering, when dry matter weight and p concentrations were measured. based on the p concentration and dry matter production, the total p accumulation was calculated. with these data, the following indices were calculated: the p uptake efficiency of roots, p use efficiency, use efficiency of available p, use efficiency of applied p and agronomic efficiency. the use of the source with higher solubility (tsp) resulted, generally, in higher total dry matter and total p accumulation in the forage grasses, in both soils. for the less reactive source (arp), the means found in the forage grasses, for use efficiency and efficient use of available p, were always higher when grown in latosol, indicating favorable conditions for the solubility of arp. the total dry matter of brachiaria brizantha was generally higher, with low p uptake, accumulation and translocation, which indicated good p use efficiency for both p sources and soils. the forage plants differed in the p use potential, due to the sources of the applied p and of the soils used. less than 10 % of the applied p was immobilized

Abstract: This article discusses the use of satellite imaging as a means to support and map out the historical expansion of the borders of S o Paulo State between the discovery of Brazil and its independence. This tool was employed in Cartography of a history, an exhibition staged at Museu Paulista/USP in 2005. The images were generated by Modis, Shuttle Radar Topographic Mission and Landsat-5, and georeferenced with the SPRING image processor as well as georectified mosaics made available by Nasa. They were then checked against a valuable set of cartographic data collected by the researchers working under the Jaime Cortes o History Chair at USP. The said set included information pertaining to the boundaries established by the Treaty of Tordesillas, with its distortions; the Map of the Courts; the captaincies; as well as the trails of bandeiras (exploring expeditions), mon es (expeditions made up and down the rivers of the S o Paulo and Minas Gerais captaincies), and tropeirismos (cattle driving routes). In other words, all the pioneering actions that helped to consolidate the territory of S o Paulo State and to shape much of Brazil′s spatial identity were traced in the images. The researchers also looked into the myth of Brazil as an island and into the purported connection between the Amazon and Paraná Prata river basins based on their geomorphologic attributes as shown on the orbital images. The results were compiled into an 800-megabyte database and displayed at Museu Paulista. This paper describes the methodological procedures used to generate and analyze the images, and provides a summary of the research findings.

Arquivos de Neuro-Psiquiatria , 2001,
Abstract: é relatado em alguns estudos que idosos deprimidos apresentam maior frequência de hipersinais ao exame de ressonancia magnética do que controles normais. No entanto os indivíduos estudados tinham fatores de risco para doen as cerebrovasculares. Este estudo analisou pacientes com história de depress o maior e indivíduos controles compatíveis, excluindo-se fatores de risco cerebrovasculares, com o objetivo de determinar se indivíduos deprimidos apresentam maior frequência de hipersinais em substancia branca e outras les es. Avaliamos a prevalência e a severidade dos hipersinais à ressonancia magnética de encéfalo em 30 pacientes idosos deprimidos e 20 controles pareados para a idade. Hipersinais de substancia branca profunda, hipersinais periventriculares e hipersinais em substancia cinzenta subcortical foram classificados em escala padr o 0-3, por dois radiologistas que desconheciam o diagnóstico clínico. N o foram encontradas diferen as significativas entre os grupos para hipersinais subcorticais. Estes achados sugerem que os fatores de risco cerebrovasculares provavelmente medeiam a rela o entre depress o e hipersinais, encontrada em estudos anteriores.
