Saberes docentes na organização do ensinio-aprendizagem: uma construção reflexiva com professoras do ensino fundamental

The present study has the objective to analyze with teachers from Elementary School the knowledge mobilized in the organization of the teaching-learning process, and its implications in the exploitation of that process. The investigation was developed with two teachers from the first years of the Elementary School, from a public school in Pau dos Ferros-RN. It adopts as basis the notion of knowledge as a set of individual and social relations that the individuals maintain with the world and with themselves, in the teaching and learning relation. (CHARLOT, 2000). It considers yet that the knowledges are immediate processes, reconstructed and mobilized by the practice of reflection, in dialogical and interactional contexts in contact with others. (BAKHTIN, 2002, 2003; VYGOTSKY, 1991, 2004, 2005). The collaborative approach was the theoretical and methodological background that oriented the investigative-educative process. By choosing a collaborative research as basis of the investigative pathway, it starts from the knowledge that the critical and collaborative reflection developed with the teachers from the first years of the Elementary School contribute to explicitate and resignify the meanings assigned to the knowledges that these teachers mobilize in the organization of the teaching-learning and its implications in this process. The results of the reflexive and investigative process developed with the teachers demonstrate that the familiar, scholastic, academic, professional, and the work knowledges lived, constitute the consciousness of being a teacher, and that these knowledges implicate in the dynamics of the process of teaching-learning, but not always the teachers take consciousness about these knowledges. The critical and collaborative reflection, mediated by the actions of describing, announcing, facing and reconstructing allowed to the participants of the research to realize the knowledges of themselves and of the other, the difficulties and possibilities in the organization of the teaching-learning process

Oralidade e escrita: a presença do discurso reportado em entrevistas jornalísticas

In this work, we intend to discuss results from a research about retextualization in gender journalistic interview, considering speech dialogical approach. Retextualization activity, which implies the production of a new text through one or more basic texts, shows the presence of reported speech as an integral unit of discursive construction. Our corpus had been extracted from a section called Nossos Valores [Our Values], present at the syndical newspaper Adurn Notícias [Adurn News], from Federal University of Rio Grande do Norte (Brazil), which weekly publishes journalistic interviews with active professors from this institution. We describe retextualised text structure by correlating it to the one from the oral text, in order to identify and describe quoted speech, as well as features of the gender in which it is inserted. It was verified that, when it comes to reported speech present in the published interviews, which are representative of the research corpus, diverse incorporation procedures of alien property‟s speech take place, especially those regarding about reported speech use. The waterish presence of the other present in dialoged texts speech transformed in monologue texts demonstrates that there is not a clear demarcation among voices in certain parts of the written text. This is confirmed during analyses of the two interview versions, in which it is not always possible to distinguish the authorship of certain propositions, which in some way can point to Bakhtin‟s concept of intentional hybridity. Beyond Bakhtin‟s contributions (1990; 2000), the theoretical principles of this work are based upon Marcuschi (1986; 1999; 2001), Matencio (2003), Authier-Revuz (1982), and Favero et al. (1997; 1998; 1999; 2000)

O circuito espacial da produção petrolífera no rio Grande do Norte

Our study refers to the state of Rio Grande do Norte against the deployment of oil activity in their territory. In this sense the aim of this work was to analyze the presence of the loop space of the oil production system linked to objects and actions on the Rio Grande do Norte territory. From the so-called "oil shock", an event that caused global developments in several countries, Petróleo Brasileiro S/A (PETROBRAS) increased investments in drilling geological basins in Brazil. In the year 1973 was drilled in the sea area well which led to commercial production of oil and gas in Rio Grande do Norte. From that point on were added in some parts of the Potiguar territory, large systems of coupled objects to actions caused by several agents. In this context, geographic situations have been reorganized due to an unprecedented space circuit production accompanied by a new circle of cooperation. In the state happen all instances of the circuit: the production, distribution and consumption. In light of the theory of the geographical area seek to direct our thoughts to the operation of these bodies, and they are linked to material and immaterial flows multiscales. This perspective allows us to think the territory of Rio Grande do Norte entered into a new territorial division of labor characterized by specialization regional production. Oil activity was implemented in the territory of Rio Grande do Norte at a time marked by productive restructuring of various economic sectors. The oil sector has been acting increasingly linked the scientific and informational, with a view to increasing productivity. The presence of this circuit demanded the territory, specifically the Mossoró, an organizational structure that is different from the vast system nationally integrated private commercial corporations to small corporations, all of them relating directly or indirectly to PETROBRAS. The flows between companies whose headquarters are located in distant states and even countries have generated a continuous movement of goods, people, information and ideas, which is also causing new materialities in the territory

Lugar, saúde e informação: os círculos de informação da atenção básica do SUS no contexto na disputa pelo conceito de saúde

Through the analysis of the informational activity at the primary care of SUS at the scale of places, this dissertation has as central objective to observe the dispute for the concepts of health and sickness, in the ambit of Brazilian Health Movement, featuring, on one hand, the clinic, biomedical or flexnerian line hegemonic, scientifically restrict and the primary frame of references for the Brazilian health politics and on the other hand a multiplicity of new proposals and critic thoughts to the current model, which have , as common characteristic, the worry with a territorial way of thinking the health context, therefore beyond the biological processes. On the first chapter we jut out with details these scientific and ideological movements, on a wider way, but also on the specificities of the public health s information politics. On the second chapter we analyze the downward health information circle at the basic care, observing the operational processes of the information s technical systems SIAB and e-SUS. On the third and last chapter, we give references to think about an upward health information circle, centered on the places, ruled by the notions of autonomy, organic solidarity and communicational density. It would possess, as method s primary horizon, the local organization of production and managing of information through the work of the Health Community Agent, privileging therefore the urgency of the most contingent needs of the people in theirs every day s life

analise da dispersao de ondas de superficie na provincia borborema, Nordeste do Brasil

The Borborema Province, Northeastern Brazil, had its internal structure investigated by different geophysical methods like gravity, magnetics and seismics. Additionally, many geological studies were also carried out to define the structural domains of this province. Despite the plethora of studies, there are still many important open aspects about its evolution. Here, we study the velocity structure of S-wave in the crust using dispersion of surface waves. The dispersion of surface waves allows an estimate of the average thickness of the crust across the region between the stations. The inversion of the velocity structure was carried out using the inter-station dispersion of surface waves of Rayleigh and Love types. The teleseismic events are mainly from the edges of the South and North American plates. The period of data collection occurred between 2007 and 2010 and we selected 7 events with magnitude above 5.0 MW and up to 40 km depth. The difference between the events back-azimuths and the interstation path was not greater than 10. We also know the depth of the Moho, results from Receiver Functions (Novo Barbosa, 2008), and use those as constrains in inversion. Even using different parameterizations of models for the inversion, our results were very similar the mean profiles velocity structure of S-wave. In pairs of stations located in the Cear´a Central Domain Borborema the province, there are ranges of depths for which the velocities of S are very close. Most of the results in the profile near the Moho complicate their interpretation at that depth, coinciding with the geology of the region, where there are many shear zones. In particular, the profile that have the route Potiguar Bacia in inter-station, had low velocities in the crust. We combine these results to the results of gravimetry and magnetometry (Oliveira, 2008) and receptor function (Novo Barbosa, 2008). We finally, the first results on the behavior of the velocity structure of S-wave with depth in the Province Borborema

Recuperação de larvas infectantes de Trichostrongylus colubriformis em três espécies de gramíneas contaminadas no verão

O experimento teve como objetivo avaliar a recuperação de larvas infectantes (L3) de Trichostrongylus colubriformis em Brachiaria decumbens cv. Australiana, Cynodon dactilon cv. Coast-cross e Panicum maximum cv. Aruana. Foram utilizados módulos experimentais constituídos por seis canteiros de 32,4 m² cada, perfazendo dois canteiros por espécie forrageira. Cada canteiro foi dividido em 36 parcelas, de 30 x 30 cm, de forma a permitir seis repetições por espécie e por altura da forragem em cada semana de colheita de material. A sobrevivência larval foi avaliada do meio do verão e até meados do outono, sob o efeito de duas alturas de poda das forragens: baixa, 5 cm e alta, 30 cm. A poda foi realizada imediatamente antes da deposição das fezes contaminadas com ovos de T. colubriformis, obtidos de ovinos, que ocorreu no dia 05/02/ 2004. A colheita das fezes e da forragem foi realizada uma, duas, quatro, oito, 12 e 16 semanas após a deposição das fezes nos canteiros experimentais. A altura da forragem foi medida em cada uma das subdivisões imediatamente antes da colheita. A forragem foi cortada rente ao solo, de uma área delimitada com o auxílio de um círculo de 10 cm de raio. As fezes foram recolhidas manualmente dos canteiros. O número de larvas infectantes recuperado foi muito pequeno em comparação com a quantidade de larvas produzidas nas culturas controle, mantidas no laboratório (máximo de 6,7% no capim Aruana com 30 cm de altura). Arecuperação de L3 das amostras fecais foi maior quando as fezes foram depositadas em meio ao capim alto (com 30 cm - P<0,05). Porém, a recuperação de L3 das forragens foi similar em ambos os cortes. em relação à concentração de L3 (número de L3/kg de matéria seca), não houve diferença entre o corte baixo e alto (P>0,05) em nenhuma das semanas experimentais. Dentre as espécies forrageiras, o capim aruana foi o que, no geral, apresentou maiores concentrações de L3 de T. colubriformis.

Antimicrobial activity of 2% chlorhexidine gluconate, 1% sodium hypochlorite and paramonochlorophenol combined with furacin against S. aureus, C. albicans, E. faecalise and P. aureginosa

OBJETIVO: Analisar a ação antimicrobiana da clorexidina a 2%, do hipoclorito de sódio a 1% e do paramonoclorofenol associado ao furacin sobre S aureus, C albicans, E faecalise e P aureginosa. METODOLOGIA: Foram utilizadas 40 placas Petri. Quatro placas foram separadas como controle negativo e em 4 outras, além do meio de cultura, semearam-se os microrganismos, com o círculo de papel, para se obter o controle positivo. em 32 placas seguiu-se a colocação de 4 círculos de filtro de papel esterilizados e impregnados das substâncias testes e controle, depositados em cada quadrante das mesmas. Os grupos foram analisados por 7 dias. Para a verificação dos resultados, usaram-se os halos de inibição de crescimento bacteriano. RESULTADOS: A clorexidina 2% foi significantemente (P<0,05) mais efetiva para todas as cepas microbianas que as demais substâncias. O hipoclorito de sódio a 1% apresentou resultados intermediários. O paramonoclorofenol associado ao furacin (PMC+F) obteve os piores resultados. CONCLUSÃO: A clorexidina obteve os melhores resultados. O PMC+F apresentou os menores halos de inibição.

Refiguração do tempo histórico pela ficção

M. Bakhtin afirma que a representação de acontecimentos, relações e processos no romance deve abranger a totalidade de uma época nela deve haver uma peculiar concatenação, literariamente expressa, espácio-temporal. Essa formulação contém elementos basilares para o entendimento e análise do romance, objeto deste estudo, Leite derramado de 2009 de Chico Buarque. A narrativa figura, pelo menos, duas grandes épocas históricas do Brasil: uma que vai do início do século XIX até 1930 e outra que vai desse momento ao início do XXI. É a representação da saga histórica da decadência de uma categoria social (fração da classe dominante), personificada na família Assumpção, com seus valores éticos e culturais, suas concepções de mundo e seu comportamento, estilizando sua dissolução social e moral. Ao fazer isso o romance coloca inúmeros problemas desde humano-existenciais até histórico-políticos para a reflexão do leitor.

Os quatro núcleos/eixos de produção da poética de Caio Fernando Abreu

This article presents a short study about the literary work of Brazilian writer Caio Fernando Abreu (1946-1996). In order to study his formal and thematic choices, we established criteria based on concepts like motif and plot (dramatic situation), as developed by Tomachevski (1976). A specific articulation between motives and dramatic situations establishes four nuclei of Abreu's literary production, which is characterized by a literary experimentation with these elements and it constructs an organic work that makes itself and/or is made in a dialogic way (Bakhtin, 1981). Firstly, the main characteristics of the four nuclei and the books that embody them will be presented. Then, we will describe how the motives and dramatic situations are re-elaborated from one nucleus to another. Not only does each nucleus features some new elements, but also contains remainders of previous ones. As such, each of Abreu's works can be considered as both the same and unique.
