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

Segregação socioespacial e turismo: estudo da representação fílmica criada pelos turistas e residentes sobre Natal Rio Grande do Norte

This study emerges and develops, from a note by Italo Calvino, who in his novel Invisible Cities advised to avoid saying "that sometimes different cities follow on the same site and with the same name, born and die without knowing, without communication among itself ". The research with a transdisciplinary work ( using elements of sociology, anthropology, geography and communication) made a reflection about segregation and tourism: poverty-richness, center-periphery, tradition- spectaclezation , the visitor-visited maping the touristic circuit and discussing about the phenomenon on the real city and touristic place: Natal and the "Sun City" - Rio Grande do Norte, studying videos produced by residents (documentary) and tourists ( posted on the Internet). Doing a comparative analysis between the realities of these two subjects (resident and tourist), the research found few similarities, many differences on the urban experience, with the existence of two distinct realities (tourist region X the periphery region). Based on theory of phenomenology, social representation, and using content analysis of film, it was noted that promotes to the visitor a trip segmented and disintegrated to daily life, culture and contact with the resident. Resident that, in largely part, lives in a unattended area, with no prospect of life (represented by Novo Horizonte Community). The confinement and segregation occurs even in his moments of leisure and cultural expressions (represented by Redinha‟s Beach), because the private an public leisure areas of tourism indirectly prevent access by people who can not contribute to the consumption on this places. This papper concluded that the tourism in Natal is an activity-phenomenon that directs and focuses on public investments for infrastructure tourist region (Ponta Negra Beach), in detriment of the poorest and periphery areas of the city

Saliva: reflection of the body

Saliva has become an important resource for evaluating physiological and pathological conditions in humans. The use of saliva has many advantages, including the simple and non-invasive method of collection and its easy, low-cost storage. With the addition of modern techniques and chemical instrumentation equipment, there has been an increase in its use for laboratory investigations, applicable for basic and clinical analyses in the fields of medicine and dentistry. The value of these methods for the diagnosis of oral and systemic diseases has been the subject of study by several researchers with the aim of increasing its use alongside complementary exams.

Four-fermion contact interactions at one-loop and the new atomic parity violation results.

We investigate the possibility that four-fermion contact interactions give rise to the observed deviation from the Standard Model prediction for the weak charge of cesium, through one-loop contributions. We show that the presence of loops involving the third generation quarks can explain such deviation.

Temporal correlator in YM32 and reflection-positivity violation

We consider numerical data for the lattice Landau gluon propagator obtained at very large lattice volumes in three-dimensional pure SU(2) Yang-Mills gauge theory (YM32). We find that the temporal correlator C(t) shows an oscillatory pattern and is negative for several values of t. This is an explicit violation of reflection positivity and can be related to gluon confinement. We also obtain a good fit for this quantity in the whole time interval using a sum of Stingl-like propagators.

Constraints on four-fermion contact interactions from precise electroweak measurements

We establish constraints on a general four-fermion contact interaction from precise measurements of electroweak parameters. We compute the one-loop contribution for the leptonic Z width, anomalous magnetic, weak-magnetic, electric and weak dipole moments of leptons in order to extract bounds on the energy scale of these effective interactions.
