Nem prêmio, nem castigo! A escola moderna como ação revolucionária dos sindicatos operários durante a Primeira República (São Paulo, 1909-1919)

A Escola Moderna n.1 (São Paulo), sob a direção do professor libertário João Penteado, ofereceu uma alternativa de formação para os filhos da classe trabalhadora, inspirando-se na Pedagogia Libertária que, desde os primeiros debates da Internacional dos Trabalhadores até as experiências educacionais de Paul Robin, inseriu a luta de classes no espaço da escola. Assim, promoveu a interface entre educação e revolução social com base nos conceitos de Demopedia e Instrução Integral, desenvolvidos respectivamente por Pierre-Joseph Proudhon e Mikhail Bakunin. O presente estudo pretende desvelar como o espaço da Escola Moderna se converteu em ação revolucionária dos sindicatos operários, colaborando para os objetivos dos anarquistas que elegeram o sindicalismo revolucionário como a tática mais adequada para o estabelecimento da sociedade livre com a qual sonharam. Deste modo, entre os anos de 1912 a 1919, quando foi sumariamente fechada pelo Departamento de Instrução Pública do Estado, a Escola Moderna promoveu a ação direta e o mutualismo entre seus estudantes, tanto para que contribuíssem com o futuro da classe trabalhadora, de acordo com suas necessidades e conforme suas condições, como também para que os organismos de classe ultrapassassem as lutas mais imediatas.

Criação de uma Lista de Cabeçalhos de Assunto para a Documentação da Biblioteca Universitária João Paulo II

O aspecto fulcral desta dissertação centra-se-à volta do desafio de procurar facilitar o acesso à informação contida na base de dados bibliográfica da Biblioteca Universitária João Paulo II (BUJPII) da Universidade Católica Portuguesa (UCP) cujo conteúdo temático tem sido até agora representado pela Classificação Decimal Universal (CDU), linguagem documental pouco acessível a grande parte dos nossos utilizadores, na sua maioria estudantes universitários que a consideram um instrumento de pesquisa pouco amigável porque estão muito pouco ou nada familiarizados com este tipo de classificação numérica preferindo o uso de palavras-chave no acesso ao conteúdo temático das obras. Com este objectivo em vista, propusemo-nos levar a cabo este trabalho de investigação fazendo a harmonização (correspondência) entre as notações da CDU, usada na classificação da colecção de fundos da BUJPII e uma lista simplificada de Cabeçalhos de Assunto da Biblioteca do Congresso, com o propósito de iniciar um processo de atribuição de cabeçalhos de assunto, mapeados a partir das notações da CDU, a parte dos referidos fundos, cuja recuperação de conteúdo tem sido feita até agora através da Classificação Decimal Universal. O estudo incidiu experimentalmente numa amostragem de monografias de áreas não indexadas mas já classificadas, cujos registos bibliográficos se encontram na base de dados da Biblioteca Universitária João Paulo II. O projecto consistiu na atribuição de cabeçalhos de assunto, traduzidos manualmente para português a partir da lista em inglês dos Cabeçalhos de Assunto da Biblioteca do Congresso (LCSH). Procurou-se que estivessem semanticamente tão próximos quanto possível dos assuntos que correspondiam às notações da Classificação Decimal Universal (CDU) com as quais as monografias tinham sido anteriormente classificadas. O trabalho foi primeiro elaborado de forma manual e depois “carregado” no software Horizon, dado ser este o sistema informático de gestão integrada em uso na Biblioteca Universitária João Paulo II, sendo o objectivo futuro a indexação de todas as áreas do seu acervo bibliográfico, como forma complementar privilegiada no acesso à informação.

Dietary predictors of serum total carotene in low-income women living in Sao Paulo, south-east Brazil

Objective Dietary intake and nutritional status of antioxidant vitamins have been reported to protect against some cancers The objective of the present study was to assess the correlations between serum levels of carotenoids (including beta-, alpha- and gamma-carotene), lycopene, retinol, alpha- and gamma-tocopherols, and dietary intakes estimated by an FFQ, among low-income women in the Brazilian Investigation into Nutrition and Cervical Cancer Prevention (BRINCA) study. Design Cross-sectional study of data for 918 women aged 21-65 years participating in the BRINCA study in Sao Paulo city. Multiple linear regression models were used with serum nutrient levels as the dependent variable and dietary intake levels as the independent variable, adjusted for confounding factors. Results In energy-adjusted analyses, the intakes of dark green and deep yellow vegetables and fruits (partial R(2) = 4.8%), total fruits and juices (partial R(2) = 1.8%), vegetables and fruits (partial R(2) = 1.8%), carrots (partial R(2) = 1.4%) and citrus fruits and juices only (partial R(2) = 0.8%) were positively correlated only with serum total carotene levels, after adjusting for serum total cholesterol concentration, age, hospital attended, smoking status. BMI and presence of cervical lesions Multiple-adjusted serum levels of carotenoids were positively correlated with intake quartiles of dark green and deep yellow vegetables and fruits and total fruits and juices independent of smoking status. Conclusions The intake of specific fruits and vegetables was an independent predictor of serum total carotene levels in low-income women living in Sao Paulo

Detection of assemblages A and B of Giardia duodenalis in water and sewage from Sao Paulo state, Brazil

Giardia duodenalis is a protozoan that parasitizes humans and other mammals and causes giardiasis. Although its isolates have been divided into seven assemblages, named A to G, only A and B have been detected in human faeces. Assemblage A isolates are commonly divided into two genotypes, AI and AII. Even though information about the presence of this protozoan in water and sewage is available in Brazil, it is important to verify the distribution of different assemblages that might be present, which can only be done by genotyping techniques. A total of 24 raw and treated sewage, surface and spring water samples were collected, concentrated and purified. DNA was extracted, and a nested PCR was used to amplify an 890 bp fragment of the gdh gene of G. duodenalis, which codes for glutamate dehydrogenase. Positive samples were cloned and sequenced. Ten out of 24 (41.6%) samples were confirmed to be positive for G. duodenalis by sequencing. Phylogenetic analysis grouped most sequences with G. duodenalis genotype AII from GenBank. Only two raw sewage samples presented sequences assigned to assemblage B. In one of these samples genotype AII was also detected. As these assemblages/genotypes are commonly associated to human giardiasis, the contact with these matrices represents risk for public health.

Listeria monocytogenes in ready-to-eat, sliced, cooked ham and salami products, marketed in the city of Sao Paulo, Brazil Occurrence, quantification, and serotyping

The preference for ready-to-eat sliced foods may pose an increased risk for food-borne diseases and a major concern is the presence of Listeria monocytogenes L monocytogenes was assessed in two types of products cooked ham and salami One hundred and thirty samples of each product were acquired in retail shops in the city of Sao Paulo and submitted to laboratory analysis The rate of positives was significantly higher in salami samples than in ham samples (62% and 0 8% respectively) L. monocytogenes counts in salami samples varied between <10 and 1900 colony-forming units per gram (CFU/g) The serotypes found in both products were as follows according to incidence 4b (37 5%) 1/2b (25%) 3b (25%) and 1/2c (12 5%) Based on the results of the present study the authors suggest that the risk of listeriosis resulting from the consumption of salami is higher than that associated with the consumption of cooked ham (C) 2010 Elsevier Ltd All rights reserved

Vehicular particulate matter emissions in road tunnels in Sao Paulo, Brazil

In the metropolitan area of Sao Paulo, Brazil, ozone and particulate matter ( PM) are the air pollutants that pose the greatest threat to air quality, since the PM and the ozone precursors ( nitrogen oxides and volatile organic compounds) are the main source of air pollution from vehicular emissions. Vehicular emissions can be measured inside road tunnels, and those measurements can provide information about emission factors of in-use vehicles. Emission factors are used to estimate vehicular emissions and are described as the amount of species emitted per vehicle distance driven or per volume of fuel consumed. This study presents emission factor data for fine particles, coarse particles, inhalable particulate matter and black carbon, as well as size distribution data for inhalable particulate matter, as measured in March and May of 2004, respectively, in the Janio Quadros and Maria Maluf road tunnels, both located in Sao Paulo. The Janio Quadros tunnel carries mainly light-duty vehicles, whereas the Maria Maluf tunnel carries light-duty and heavy-duty vehicles. In the Janio Quadros tunnel, the estimated light-duty vehicle emission factors for the trace elements copper and bromine were 261 and 220 mu g km(-1), respectively, and 16, 197, 127 and 92 mg km(-1), respectively, for black carbon, inhalable particulate matter, coarse particles and fine particles. The mean contribution of heavy-duty vehicles to the emissions of black carbon, inhalable particulate matter, coarse particles and fine particles was, respectively 29, 4, 6 and 6 times higher than that of light-duty vehicles. The inhalable particulate matter emission factor for heavy-duty vehicles was 1.2 times higher than that found during dynamometer testing. In general, the particle emissions in Sao Paulo tunnels are higher than those found in other cities of the world.

Ozone formation potentials of volatile organic compounds and ozone sensitivity to their emission in the megacity of Sao Paulo, Brazil

In the present study, a three-dimensional Eulerian photochemical model was employed to estimate the impact that organic compounds have on tropospheric ozone formation in the Metropolitan Area of Sao Paulo (MASP). In the year 2000, base case simulations were conducted in two periods: August 22-24 and March 13-15. Based on the pollutant concentrations calculated by the model, the correlation coefficient relative to observations for ozone ranged from 0.91 to 0.93 in both periods. In the simulations employed to evaluate the ozone potential of individual VOCs, as well as the sensitivity of ozone to the VOC/NO(x) emission ratio, the variation in anthropogenic emissions was estimated at 15% (according to tests performed previously variations of 15% were stable). Although there were significant differences between the two periods, ozone concentrations were found to be much more sensitive to VOCs than to NO(x) in both periods and throughout the study domain. In addition, considering their individual rates of emission from vehicles, the species/classes that were most important for ozone formation were as follows: aromatics with a kOH>2x 10(4) ppm(-1) min(-1); olefins with a kOH 7 x 10(4) ppm(-1) min(-1); olefins with a kOH 7 x 10(4) ppm(-1) min(-1); ethene; and formaldehyde, which are the principal species related to the production, transport, storage and combustion of fossil fuels.

Sediment-contact fish embryo toxicity assay with Danio rerio to assess particle-bound pollutants in the Tiete River Basin (Sao Paulo, Brazil)

The Tiete River and its tributary Pinheiros River receive a highly complex organic and inorganic pollutants load from sanitary sewage and industrial sources, as well as agricultural and agroindustrial activities. The aim of the present study was to evaluate the embryotoxic and teratogenic effects of sediments from selected locations in the Tiete River Basin by means of the sediment contact embryo toxicity assay with Danio rerio, in order to provide a comprehensive and realistic insight into the bioavailable hazard potential of these sediment samples. Lethal and sub-lethal effects were recorded, and high embryo toxicity could be found in the samples not only in the vicinity of the megacity Sao Paulo (Billings reservoir and Pinheiros River samples), but also downstream (in the reservoirs Barra Bonita, Promissao and Tres Irmaos). Results confirm that most toxicity is due to the discharges of the metropolitan area of Sao Paulo. However, they also indicate additional sources of pollutants along the river course, probably from industrial, agricultural and agroindustrial residues, which contribute to the degradation of each area. The sediment contact fish embryo test showed to be powerful tool to detect embryo toxicity in sediments, not only by being a sensitive method, but also for taking into account bioavailability. This test provides an ecological highly realistic and relevant exposure scenario, and should therefore be added in ecotoxicological sediment quality assessments. (C) 2011 Elsevier Inc.

Successional stage and geographic features determine floristic similarity among Atlantic Forest remnants, Sao Paulo State, Brazil

Analysis of floristic similarity relationships between plant communities can detect patterns of species occurrence and also explain conditioning factors. Searching for such patterns, floristic similarity relationships among Atlantic Forest sites situated at Ibiuna Plateau, Sao Paulo state, Brazil, were analyzed by multivariate techniques. Twenty one forest fragments and six sites within a continuous Forest Reserve were included in the analyses. Floristic composition and structure of the tree community (minimum dbh 5 cm) were assessed using the point centered quarter method. Two methods were used for multivariate analysis: Detrended Correspondence Analysis (DCA) and Two-Way Indicator Species Analysis (TWINSPAN). Similarity relationships among the study areas were based on the successional stage of the community and also on spatial proximity. The more similar the successional stage of the communities, the higher the floristic similarity between them, especially if the communities are geographically close. A floristic gradient from north to south was observed, suggesting a transition between biomes, since northern indicator species are mostly heliophytes, occurring also in cerrado vegetation and seasonal semideciduous forest, while southern indicator species are mostly typical ombrophilous and climax species from typical dense evergreen Atlantic Forest.

Diversity of Somatic Coliphages in Coastal Regions with Different Levels of Anthropogenic Activity in Sao Paulo State, Brazil

Bacteriophages are the most abundant and genetically diverse viruses on Earth, with complex ecology in both quantitative and qualitative terms. Somatic coliphages (SC) have been reported to be good indicators of fecal pollution in seawater. This study focused on determining the concentration of SC and their diversity by electron microscopy of seawater, plankton, and bivalve samples collected at three coastal regions in Sao Paulo, Brazil. The SC counts varied from < 1 to 3.4 x 103 PFU/100 ml in seawater (73 samples tested), from < 1 to 4.7 x 10(2) PFU/g in plankton (46 samples tested), and from < 1 to 2.2 x 10(1) PFU/g in bivalves (11 samples tested). In seawater samples, a relationship between the thermotolerant coliforms and Escherichia coli and SC was observed at the three regions (P = 0.0001) according to the anthropogenic activities present at each region. However, SC were found in plankton samples from three regions: Baixada Santista (17/20), Canal de Sao Sebastiao (6/14), and Ubatuba (3/12). In seawater samples collected from Baixada Santista, four morphotypes were observed: A1 (4.5%), B1 (50%), C1 (36.4%), and D1 (9.1%). One coliphage, Siphoviridae type T1, had the longest tail: between 939 and 995 nm. In plankton samples, Siphoviridae (65.8%), Podoviridae (15.8%), Microviridae (15.8%), and Myoviridae (2.6%) were found. In bivalves, only the morphotype B1 was observed. These SC were associated with enteric hosts: enterobacteria, E. coli, Proteus, Salmonella, and Yersinia. Baixada Santista is an area containing a high level of fecal pollution compared to those in the Canal de Sao Sebastiao and Ubatuba. This is the first report of coliphage diversity in seawater, plankton, and bivalve samples collected from Sao Paulo coastal regions. A better characterization of SC diversity in coastal environments will help with the management and evaluation of the microbiological risks for recreation, seafood cultivation, and consumption.

Mutagenicity and DNA adduct formation of PAH, nitro-PAH, and oxy-PAH fractions of atmospheric particulate matter from Sao Paulo, Brazil

Urban particulate matter (UPM) contributes to lung cancer incidence. Here, we have studied the mutagenic activity and DNA adduct-forming ability of fractionated UPM extractable organic matter (EOM). UPM was collected with a high-volume sampler in June 2004 at two sites, one at street level adjacent to a roadway and the other inside a park within the urban area of the city of Sao Paulo, Brazil. UPM was extracted using dichloromethane, and the resulting EOM was separated by HPLC to obtain PAH, nitro-PAH, and oxy-PAH fractions which were tested for mutagenicity with the Salmonella strains TA98 and YG1041 with and without S9 metabolic activation. The PAH fraction from both sites showed negligible mutagenic activity in both strains. The highest mutagenic activity was found for the nitro-PAH fraction using YG1041 without metabolic activation; however, results were comparable for both sites. The nitro-PAH and oxy-PAH fractions were incubated with calf thymus DNA under reductive conditions appropriate for the activation of nitro aromatic compounds, then DNA adduct patterns and levels were determined with thin-layer chromatography (TLC) (32)p-postlabeling method using two enrichment procedures-nuclease PI digestion and butanol extraction. Reductively activated fractions from both sites produced diagonal radioactive zones (DRZ) of putative aromatic DNA adducts on thin layer plates with both enrichment procedures. No such DRZ were observed in control experiments using fractions from unexposed filters or from incubations without activating system. Total adduct levels produced by the nitro-PAH fractions were similar for both sites ranging from 30 to 45 adducts per 10(8) normal nucleotides. In contrast, the DNA binding of reductively activated oxy-PAH fractions was three times higher and the adduct pattern consisted of multiple discrete spots along the diagonal line on the thin layer plates. However, DNA adduct levels were not significantly different between the sampling sites. Both samples presented the same levels of mutagenic activity. The response in the Salmonella assay was typical of nitroaromatics. Although, more mutagenic activity was related to the nitro-PAH fraction in the Salmonella assay, the oxy-PAH fractions showed the highest DNA adduct levels. More studies are needed to elucidate the nature of the genotoxicants occurring in Sao Paulo atmospheric samples. (C) 2008 Elsevier B.V. All rights reserved.

Limites do crescimento urbano: questão sócio-ambiental e intervenção urbana em São Paulo: estudo de caso

É possível coexistência cooperativa entre crescimento urbano e proteção ambiental? Partindo dessa indagação o estudo busca apreender e explicitar maneiras de pensar e agir, ações e intenções de atores sociais e institucionais diversos envolvidos em processos de intervenção urbana em São Paulo. A análise privilegia os contextos emergentes neste final de século na cidade (1983 - 1993): a emergência da questão sócio-ambiental (a pobreza moderna e o fim da natureza) e da transição democrática (ampliação do espaço público e busca da cidadania). Aborda a introdução da idéia de Desenvolvimento Sustentado como base teórica das intervenções no espaço urbano, discute as mutações da questão urbana e o florescimento de políticas públicas sócio-ambientais no espaço urbano em São Paulo. A base empírica do estudo assenta-se na Região Administrativa de Itaquera, enfocando o caso do Pólo Industrial e Ecológico de Itaquera. O argumento central é que a percepção que atores diversos tem das mutações no espaço urbano e nas questões públicas os influenciam na elaboração de instrumentos de intervenção e gestão da cidade, a partir de critérios de desenvolvimento econômico e proteção ambiental.

O efeito da aglomeração industrial no desempenho econômico das firmas : uma análise exploratória aplicada ao setor de confecções do Estado de São Paulo

Verifica-se hoje, no Brasil, a emergência de uma série de estudos, tanto no lado acadêmico quanto no lado governamental e empresarial, relacionados às aglomerações industriais, mais notadamente clusters e Arranjos Produtivos Locais (APLs). Contudo, a maioria destes se direciona a abordagens metodológicas qualitativas, deixando o aspecto quantitativo ainda pouco explorado. Outro fato também constatado sobre estes estudos é que poucos são aqueles que se direcionam a avaliar o desempenho das firmas localizadas em aglomerações industriais, em comparação com as não aglomeradas. Este trabalho teve como objetivo preencher parcialmente esta lacuna. Marcado por uma abordagem quantitativa, buscou-se avaliar como as firmas aglomeradas se desempenham economicamente em relação às não aglomeradas. Dado o aparente ganho de competitividade do setor de confecções brasileiro e a importância relativa na economia que este voltou a adquirir após décadas de decadência, as firmas deste setor localizadas no estado de São Paulo foram as escolhidas para a análise. Para alcançarmos este objetivo, foi utilizada uma base de dados secundários que, conjugada com informações relativas às aglomerações industriais existentes no estado de São Paulo, permitiu avaliar o desempenho das firmas de confecções através de medidas relacionadas ao conceito de Valor Adicionado. Contrariando as expectativas geradas pela revisão de literatura, foi constatada a ausência de evidências que confirmem que as firmas localizadas em aglomerações industriais se desempenhem melhor do que as firmas não aglomeradas. Opondo-se de forma mais intensa às expectativas, foi constatado que as firmas localizadas na cidade de São Paulo, região com a maior aglomeração de firmas do setor de confecções, possuem seu desempenho econômico prejudicado. Todavia, dado o caráter exploratório do estudo, os resultados não devem ser generalizados, ficando estes restritos às empresas componentes da amostra.

Análise de um novo modelo de governança para hospitais públicos no Brasil segundo a abordagem dos custos de transação: o caso das organizações sociais no estado de São Paulo

Esta tese sustenta que a implantação de modelos híbridos de governança em organizações ou sistemas que antes eram governados por tipos hierarquizados cria novos custos de transação e que isso não impede a continuidade nem a expansão desse modelo porque a sua escolha não é unicamente baseada na minimização dos custos de transação, mas também nos efeitos de performance proporcionados. Para chegar a essa conclusão, investigaram-se as características das transações referentes à contratação de serviços hospitalares pela Secretaria de Estado da Saúde de São Paulo, os custos decorrentes dessas características associados aos problemas típicos de governança, e o desempenho das organizações após a implantação do modelo. Para estabelecer tal relação, realizou-se um estudo comparativo entre três hospitais públicos estaduais governados por Organizações Sociais de Saúde – OSS – e três hospitais da administração direta, com portes e perfis assistenciais similares. Foram entrevistados os atores-chave dos hospitais e da área responsável pela gestão dos contratos com as OSS e analisados relatórios e os dados oficiais do Ministério da Saúde e da Secretaria Estadual de Saúde sobre o desempenho dos hospitais escolhidos. Concluiu-se que a governança das OSS incrementou os custos de transação em cerca de 1% dos gastos totais, mas que os hospitais segundo esse modelo apresentaram um desempenho altamente satisfatório em comparação com o grupo de hospitais da administração direta. Outra descoberta do estudo é que a introdução do modelo das OSS reduziu, nesses hospitais, os níveis de incerteza comportamental e ambiental, que ficaram significativamente mais baixas do que os percebidos pelos hospitais da administração direta.
