O papel da leitura nas aulas de inglês: uma análise segundo a percepção dos professores do ensino médio de escolas públicas estaduais de Natal

This dissertation aims at investigating the teachers beliefs about the role of the reading ability in English at public state high schools in Natal and identifying the social value of the process of learning English for students of a foreign language. From the understanding of studies on reading, both in the field of Cognitive Psychology, as in Gibson & Levin (1975), as in the area of Psycholinguistics, as in Goodman (1970) and Del Re (2006), We researched the teachers perceptions about the skills and competencies that should permeate their educational practices, through their knowledge about theories of language acquisition as Cognitivism (Piaget, 1961) and Social Interactionism (Vygotsky, 1979) and the official documents (PCNEM, 1999; PCN+, 2002 ) that are the parameters for teaching a foreign language. We took into consideration other factors that influence the choice of the goals and the objectives to be worked out, such as: intensity of teachers workload, number of classes and students per class for each teacher, materials and technologies available, among other factors that will play an important role in the choice of the appropriate methodologies. To conduct a case study, two questionnaires were used in the construction of direct interviews with fourteen English teachers in twenty schools. According to data on the teachers beliefs we could find that for them the reading ability does not seem to have an special treatment in the teaching of a foreign language due to factors that undermine this process and therefore make teachers do not realize the real objectives of teaching English at public state high schools in Natal. As a consequence, the current process of education complicates the formation of autonomous learners capable of fighting for a social transformation

O artigo relata pesquisa que visou, entre outros objetivos, identificar a presença do estresse, a sintomatologia e as fases apresentadas pelos professores de 1ª a 4ª série do Ensino Fundamental atuantes em escolas públicas estaduais de uma cidade do Interior de São Paulo. Participaram do estudo 175 professores, perfazendo, aproximadamente, 70% dos profissionais de Ensino Básico I (PEB-I) em atuação no município. Para obtenção dos objetivos foram utilizados dois instrumentos de coleta de dados: o ISSL (Inventário de Sintomas de Estresse) e um questionário para caracterizar a população pesquisada. A pesquisa revelou que 56,6% dos professores estão experimentando estresse, cujos principais sintomas presentes são: sensação de desgaste físico constante, cansaço constante, tensão muscular, problemas com a memória, irritabilidade excessiva, cansaço excessivo, angústia/ansiedade diária, pensar constantemente em um só assunto e irritabilidade sem causa aparente.

A assistência estudantil e as cotas sociais nas universidades estaduais do nordeste: as faces do acesso ao direito

This paper discusses about the higher education in Brazilian society highlighting the struggle of the working class, as concerning the access to public universities, as well as highlights the contradictions implicit in social quotas adopted by Higher Education Institutions (HEIs) . The aim of this paper is on presenting the analysis of student assistance of the state universities in the Northeast that adopt quotas as social criteria of access for its students , presenting investigative locus as the following universities : UERN , UEPB , UPE and UNEAL . The paper presents the results of a qualitative study , based on a documentary analysis , based on dialectical and historical materialism in which she performed the reading of data from the following analytical categories: Higher Education, Social Quotas and Student Assistance. As main results, it is emphasized that the implementation of quotas as a means of access to higher education was not decisive for the form of planning and implementation of student assistance the university investigated; latent heterogeneity is that universities deal with actions to support student residence. And it is this heterogeneity and the variation in the conduct and understanding of student assistance , reflecting the lack of prioritization with the actions of the context of HEIs ; support programs are to stay focused on central campuses which are located the administrative offices of the universities, penalizing students enrolled in advanced units; also highlight that there is no link between the programs and projects related to student assistance with actions related to teaching, research and extension in universities investigated , which ultimately characterize the student assistance as an isolated action and punctual

Population structure of the malaria vector Anopheles darlingi in Rondônia, Brazilian Amazon, based on mitochondrial DNA

Anopheles darlingi is the most important Brazilian malaria vector, with a widespread distribution in the Amazon forest. Effective strategies for vector control could be better developed through knowledge of its genetic structure and gene flow among populations, to assess the vector diversity and competence in transmitting Plasmodium. The aim of this study was to assess the genetic diversity of An. darlingi collected at four locations in Porto Velho, by sequencing a fragment of the ND4 mitochondrial gene. From 218 individual mosquitoes, we obtained 20 different haplotypes with a diversity index of 0.756, equivalent to that found in other neotropical anophelines. The analysis did not demonstrate significant population structure. However, haplotype diversity within some populations seems to be over-represented, suggesting the presence of sub-populations, but the presence of highly represented haplotypes complicates this analysis. There was no clear correlation among genetic and geographical distance and there were differences in relation to seasonality, which is important for malarial epidemiology.

Avaliação da incidência da deficiência de Glicose-6-Fosfato Desidrogenase (G6PD) e perfil hematológico em indivíduos de uma região de Rondônia

O estudo compreendeu a avaliação da deficiência de Glicose-6-Fosfato Desidrogenase (G6PD) e perfil hematológico em 122 indivíduos (69 homens e 53 mulheres), com idade variando entre 3 a 84 anos, selecionados conforme a aceitação em participação no estudo, residentes na área urbana e rural do município de Porto Velho, Rondônia, Brasil, no período de julho de 2003 a agosto de 2004. A análise foi realizada utilizando-se o método da glicose NaNO2, e hemograma completo. Foram detectados quatro indivíduos do sexo masculino com deficiência da G6PD, sendo 5,8% entre os homens e 3,3% do total analisado. Dos indivíduos com deficiência da G6PD nenhum apresentava malária, através de diagnóstico realizado pela gota espessa corado pelo Giemsa. Entre os homens, 19 (27,5%) apresentaram malária, sendo 15 por Plasmodium vivax e quatro por Plasmodium falciparum; 48 (69,5%) apresentaram valores de hemoglobina abaixo de 14,0 g/dl, e 26 (37,6%) apresentaram valores eritrocitários abaixo do 4,5 milhões/mm³. Entre as mulheres apenas duas (3,7%) apresentaram malária por Plasmodium vivax; 24 (45,2%) apresentaram valores de hemoglobina abaixo de 12,0 g/dl, e 12 (22,6%) apresentaram massa eritrocitária abaixo de 4,0 milhões/mm³. A eosinofilia esteve presente em 47 (68,1%) dos homens e em 34 (64,1%) das mulheres. A incidência de deficiência da G6PD foi significativa na população masculina que procurou assistência médica devido a sintomas febris. Considerando que a primaquina é utilizada para o tratamento da malária vivax e falciparum, o risco de ocorrência de hemólise intravascular grave entre os indivíduos é significante. O teste utilizado é muito simples e de baixo custo e sugerimos a adoção desta metodologia na rotina dos laboratórios de atendimento público em áreas endêmicas de malária.

O professor coordenador pedagógico nas escolas estaduais paulistas: da articulação pedagógica ao gerenciamento das reformas educacionais

Este artigo apresenta os principais resultados de uma pesquisa concluída que teve como objeto de estudo a função de coordenação pedagógica na rede estadual paulista, com destaque para o trabalho do professor coordenador pedagógico (PCP). A partir de um estudo bibliográfico-documental, analisamos as principais resoluções publicadas pela Secretaria de Estado da Educação de São Paulo no período de 1996 a 2010. Para a definição do período de análise, foram consideradas as sucessivas medidas educacionais de natureza neoliberal ocorridas na referida rede de ensino. A partir das resoluções selecionadas, foram estabelecidas algumas categorias de análise relacionadas à função: denominação, justificativa e atribuições legais; requisitos necessários para os professores coordenadores e critérios de escolha; avaliação do trabalho realizado e bibliografia básica solicitada nos processos seletivos. A análise dos documentos legais permite identificar a apropriação da função pelas reformas educacionais recentes, reconhecendo as implicações para o trabalho docente e para a organização da escola. Influenciadas por princípios gerencialistas e performáticos, as reformas educacionais promoveram profundas alterações na natureza do trabalho do professor coordenador pedagógico, o qual, de articulador no âmbito da escola, passou a ser legalmente o sujeito responsável pela disseminação das medidas oficiais e pelo controle das atividades docentes.

Desempenho das metodologias convencionais de quantificacao de reservas<>9d\estudo de um deposito de niquel

Ten working-groups were formed for estimation of nickel ore reserves, associated to an ultrabasic body, at Ipanema, MG. Each group employed six methods: parallel sections, isolines, triangles, polygons, blocks and statistical method. The triangles method showed more variability, and the smallest dispersion was obtained by the polygons method; the other methods induced fluctuations in relation to the mean. Top and bottom ore irregularities produced difficulties in the performance of the parallel sections method. Different ways of application of isolines method also produced some variations. Excepting for few calculated data, the overall results are very close to 2 200 000 t or ore. -English summary

Urban and suburban malaria in Rondônia (Brazilian Western Amazon) II. Perennial transmissions with high anopheline densities are associated with human environmental changes

Longitudinal entomological surveys were performed in Vila Candelária and adjacent rural locality of Bate Estaca concomitantly with a clinical epidemiologic malaria survey. Vila Candelária is a riverside periurban neighborhood of Porto Velho, capital of the state of Rondônia in the Brazilian Amazon. High anopheline densities were found accompanying the peak of rainfall, as reported in rural areas of the region. Moreover, several minor peaks of anophelines were recorded between the end of the dry season and the beginning of the next rainy season. These secondary peaks were related to permanent anopheline breeding sites resulting from human activities. Malaria transmission is, therefore, observed all over the year. In Vila Candelária, the risk of malaria infection both indoors and outdoors was calculated as being 2 and 10/infecting bites per year per inhabitant respectively. Urban malaria in riverside areas was associated with two factors: (1) high prevalence of asymptomatic carriers in a stable human population and (2) high anopheline densities related to human environmental changes. This association is probably found in other Amazonian urban and suburban communities. The implementation of control measures should include environmental sanitation and better characterization of the role of asymptomatic carriers in malaria transmission.

Dose de exposição radiométrica de granitos do estado de Rondônia, Brasil

This work evaluated the activity concentration of the radioelements K, eU and eTh in samples of granites from Rondônia State, Brazil. The statistical analysis of the data indicated that they fit lognormal distributions. The modal values correspond to about 11% for K, 29 ppm for eU and 85 ppm for eTh. Directsignificant correlations were found among the concentrations of the three radioelements, i.e. r = 0.71 (between K and eU), r = 0.72 (between K and eTh), andr = 0.72 (between eU and eTh), suggesting congruency of their accumulation in minerals occurring in the rocks analyzed. The activity concentration data allowed estimate the absorbed dose rate in air at 1 m above the ground, which also fits a lognormal distribution characterized by a mode of 2.7 mSv/y that is slightly higher than the average worldwide exposure of 2.4 mSv/y. The results obtained also allowed evaluate if the granites analyzed are radiometrically suitable as building and ornamental materials. © 2009 Sociedade Brasileira de Geofísica.

Mechanical tillage of degraded mining areas at Jamari national forest (Amazonian forest, Rondônia - BR)

According to the environmental legislation enforced in Brazil and the process of marketing globalization, the commitment of the nations to the preservation of the environment is intensified. By reason of nature's negative responses to its intensive use, awareness then appears from enterprises and agencies about how the anthropic action over the environment needs to be minimized, becoming a challenge: development and sustainability. In this context, the present work made use of the Mechanical tillage of the soil, as a technique to apply, in a large scale, the strategies and methods to recover mined areas that were researched and developed experimentally by researchers on a theme project about the recovering of degraded areas. This work was conducted in the Amazon ecosystem, inside the Jamari National Forest - Rondônia (FLONA do Jamari), in deactivated cassiterite mines. The objectives of this work were to: Develop a computational program capable of managing a database and assist in the selection of machines and preparation methods to execute the operations of topographical reconstitution and tillage of surfaces in areas degraded by the mineral exploitation of cassiterite. Use the program that was developed in the planning of costs and operational development, for the operations required in the strategies for recovering the areas. Analyze the vegetable productivity in the mobilized areas and the quality of the superficial mobilization, making use of indicators and tillage methods. Evaluate, through biological indicators, the efficiency of the recovery strategies and techniques that were mechanized and applied on the location. The results showed that the developed computational program (SGMAD) served the methodological purposes (the analysis of costs and operational capacity) established for the planning and the selection of the tillage machines and methods in the areas of mineral exploitation of cassiterite. The applied methods and quality of the superficial mobilization were significant to the development of leguminous plants in the areas. The use of biological indicators (microbial biomass and enzymatic activity) in the evaluation of the adopted techniques and strategies revealed that the planting of leguminous plants and their posterior incorporation have been promoting gradually positive alterations in some of the analyzed soil/substract parameters. © 2010 WIT Press.
