As relações entre desenho e escrita no processo de apropriação da linguagem escrita

Este trabalho se constitui a partir dos estudos realizados na linha de pesquisa Educação e Linguagens, do Programa de Pós-Graduação em Educação da Universidade Federal do Espírito Santo. Adota uma abordagem sócio-histórica para a investigação qualitativa no campo das Ciências Humanas e tem por objetivo investigar as relações entre desenho e escrita elaboradas por crianças de quatro anos de idade que frequentavam uma instituição de educação infantil. Para a análise dos dados produzidos, toma por base os pressupostos teóricos de Mikhail Bakhtin, a partir da perspectiva enunciativo-discursiva, cuja abordagem de linguagem ajuda a compreender o desenho e a escrita em sua dimensão discursiva, como enunciação. Com base nos processos observados nas relações ensino-aprendizagem e na interação verbal entre os sujeitos da pesquisa, seleciona, para a primeira parte do estudo, situações de ensino-aprendizagem vivenciadas pelas crianças e pela professora na sala de atividades. Na segunda parte das análises, seleciona produções realizadas para interlocutores reais e imaginários e finaliza com a análise de dados, inferindo que a distinção entre desenho e escrita é uma construção escolar, sustentando, desse modo, a tese de que as diferentes linguagens mantêm relações entre si no curso do processo de apropriação da linguagem escrita e essa coexistência permite a ampliação da imaginação criadora, a produção de marcas singulares e idiossincráticas nos textos produzidos pelas crianças, além de proporcionar uma compreensão de como as crianças se constituem no mundo.

Ação mediada em aulas de Biologia : um enfoque a partir dos conceitos de fotossíntese e respiração celular

Esta pesquisa teve como objetivo investigar o papel da ação mediada na configuração dos sentidos que perpassam um processo de interação discursiva em uma sala de aula de Biologia, da 1ª série do ensino médio, de uma escola pública estadual do município de Vitória-ES, durante aulas que visavam abordar os conceitos de fotossíntese e respiração celular. Para isso, apoiamo-nos na tese de que a ação mediada qualificada como organizada, dialógica, compreensiva e interativa favorece a formação desses conceitos científicos por alunos de ensino médio. Assim, partimos de uma concepção teórico-metodológica ancorada na matriz histórico-cultural. A pesquisa-ação crítico-colaborativa foi utilizada como aporte metodológico e os instrumentos de coleta de dados se basearam em observações do cotidiano escolar e da sala de aula com registros em diários de campo, filmagem das aulas em vídeo, questionários, provas escritas dos alunos e entrevistas reflexivas. As análises dos dados se basearam na análise microgenética proposta por Vigotski, complementada com uma análise compreensiva ancorada nas ideias de Bakhtin. Dois grandes eixos de análise foram delimitados: 1 - a ação mediada no trabalho com os alunos; 2 - os enunciados e sentidos produzidos durante o processo da pesquisa na perspectiva da professora. Os resultados revelam evidências de que a ação mediada qualificada como intencional, organizada, dialógica, compreensiva e interativa favorece a formação dos conceitos científicos de fotossíntese e respiração celular por alunos do ensino médio, promovendo um ensino fecundo, na concepção defendida por Vigotski. Os resultados indicam também que o processo de pesquisa-ação crítico- colaborativa apresentou resultados positivos no que concerne à formação continuada da professora de Biologia. Concluímos que se fazem necessários investimentos em programas de formação de professores que procuram articular escola e universidade, integrando formação inicial e continuada de professores. Para isso, defendemos que esse processo de formação seja feito dentro de uma perspectiva crítica e colaborativa, baseada em uma ação mediada intencional e dialógica que favoreça o desenvolvimento de um ensino fecundo

Towards Emotional Interaction: Using Movies to Automatically Learn Users' Emotional States

The HCI community is actively seeking novel methodologies to gain insight into the user’s experience during interaction with both the application and the content. We propose an emotional recognition engine capable of automatically recognizing a set of human emotional states using psychophysiological measures of the autonomous nervous system, including galvanic skin response, respiration, and heart rate. A novel pattern recognition system, based on discriminant analysis and support vector machine classifiers is trained using movies’ scenes selected to induce emotions ranging from the positive to the negative valence dimension, including happiness, anger, disgust, sadness, and fear. In this paper we introduce an emotion recognition system and evaluate its accuracy by presenting the results of an experiment conducted with three physiologic sensors.

The host-tourist interaction in a world heritage site: the case of Guimarães

Guimarães, in the northwest of Portugal, is a city of strong symbolic and cultural significance and its nomination by UNESCO as world heritage, in 2001, enlarged its tourism potential. In this paper we present a few results of a survey that envisaged capturing the Guimarães residents’ perceptions of tourism impacts and their attitudes towards tourists. Specifically, one analyzes the type of relationship that exists between some socio-demographic groups and the perceived tourism impacts, as well as their socio-characteristics and the existing level of interaction between residents and tourists. The survey was implemented between January and March 2010 to a convenience sample of 540 inhabitants of the municipality of Guimarães resulting in 400 questionnaires with complete data. For this, we made use of various statistical techniques. Using a factorial analysis, we can conclude that the three factors used explain 52.3% of the variance contained in the original variables obtained from the survey. By another side, using a logit model in the analysis and taking as the dependent variable the frequent or very frequent contact with tourists, we found that only the variables referred to perceived positive impacts of tourism, education and the place of residence in urban areas have shown to be statistically significant. We are aware of the multiple ways the issue of residents’ perceptions and attitudes towards tourism can be approached and of the difficulties to get useful policy-oriented insights. This paper is a step in that trail.

Student stress and quality of education

Today, managers are increasingly interested in knowing how the work in organizations aftects employees' health. Less common is the interest in stress erupting in the academic community - among students, faculty and administrators. The authors present a reflection paper focused on student stress. In this paper, they first examine McLean 's model of context, vulnerability and stressors. This model provides the framework for the student surveys and for the entire paper. Based on the students surveys, an assessment is made of how asma" group of students are coping with stress. The paper fina"y suggests what can be done by students, faculty, and administrators to insta" and/or improve social support systems that might reduce the harmful eftects of stress on students and thus impact the quality of education.

Access to information: assessment of the use of automated interaction technologies in call centers

With the purpose of at lowering costs and reendering the demanded information available to users with no access to the internet, service companies have adopted automated interaction technologies in their call centers, which may or may not meet the expectations of users. Based on different areas of knowledge (man-machine interaction, consumer behavior and use of IT) 13 propositions are raised and a research is carried out in three parts: focus group, field study with users and interviews with experts. Eleven automated service characteristics which support the explanation for user satisfaction are listed, a preferences model is proposed and evidence in favor or against each of the 13 propositions is brought in. With balance scorecard concepts, a managerial assessment model is proposed for the use of automated call center technology. In future works, the propositions may become verifiable hypotheses through conclusive empirical research.

Interaction between information systems and work in the Brazilian banking sector

This article presents the results of a research to understand the conditions of interaction between work and three specific information systems (ISs) used in the Brazilian banking sector. We sought to understand how systems are redesigned in work practices, and how work is modified by the insertion of new systems. Data gathering included 46 semi-structured interviews, together with an analysis of system-related documents. We tried to identify what is behind the practices that modify the ISs and work. The data analysis revealed an operating structure: a combination of different practices ensuring that the interaction between agents and systems will take place. We discovered a structure of reciprocal conversion caused by the increased technical skills of the agent and the humanization of the systems. It is through ongoing adjustment between work and ISs that technology is tailored to the context and people become more prepared to handle with technology.

O professor frente aos processos de aprendizagem da leitura : o combate às dificuldades

RESUMO: A aprendizagem da leitura é uma conquista primordial na trajetória de vida de uma criança. A educação, atualmente, percorre grandes e diferentes discussões, e as dificuldades de aprendizagem na leitura são uma realidade visível, comprovadas através de pesquisas. Contudo devem ser vencidas. O presente estudo tem como proposta identificar as concepções e estratégias de um grupo de professores que atuam diretamente com o aluno no âmbito da aprendizagem formal da leitura, no processo do ato de ler. Conhecer as práticas pedagógicas que são desenvolvidas na sala de aula, as explicações para o sucesso e o insucesso na aprendizagem da leitura. A forma como o aluno aprende e verificar diretamente, a partir de um grupo de alunos, suas dificuldades de não saber ler, sentidas pelos próprios, e como o professor as soluciona, suas explicações encontradas para as dificuldades de aprendizagem, e o impacto que causam na vida pessoal e social do aprendente e do ensinante. Saber o que fazer e como fazer quando se descobrem falhas do aluno ou do método na compreensão da leitura é uma das características das mais desejáveis e essencial no desenvolvimento do ensino da leitura e uma das diferenças mais acentuadas entre professores aplicados e os destituídos de um compromisso sagrado no seu papel de educador. Para atender aos objetivos pretendidos, foram realizadas entrevistas semi–estruturadas, sustentadas por roteiros, com alunos (20) e professores (10) em duas escolas públicas municipais do ciclo fundamental na cidade de Aracaju. Os resultados apontam para um desconhecimento dos métodos e das teorias cognitivas. No que tange aos alunos percebe-se a dificuldade, sentida pelo próprio aluno em não saber ler, como algo corriqueiro. Os achados deste estudo nos fazem pensar que o professor munícipe precisa rever seus métodos e processos de educação, sem os quais continuaremos a assistir um sistema educacional desmotivado e indiferente ao desenvolvimento de competências e capacidades críticas no processamento da aprendizagem da leitura no primeiro ano do Ciclo Básico. ABSTRACT: The learning of reading is a prime achievement on the path of a child‟s life. Education, nowadays, courses large and different discussions and the learning difficulties are easily seen, proved by researches. However they must be overcome. This article has as proposal to identify the conceptions and strategies of a teacher‟s group that acts directly with the student in the area of formal learning of reading, it means the reading process. And also to know the teaching practices that are developed in classroom, the explanations to the achievement or failure of reading. The way how the student learns and to verify directly, based on a group of students, their difficulties experienced by themselves, and how the teacher solve those, his explanations about the difficulties that were found, and the impact they bring to learner‟s and teacher‟s personal and social lives. to know what to do and how to do when student‟s flaws or imperfections on the reading comprehension method are found is one of the most desirable and essential characteristics on the development of (he reading learning)and one of the most pointed differences by teachers concerned and unconcerned about their commitment to the teacher role. To attend to the claimed aims, it has been done semi structured interviews, held by a list of topics, with twenty students and ten teachers in two public schools in Aracaju city. The results show ignorance on the methods and theories. When it comes to the students it‟s easy to see that the difficulty is faced by those who can‟t read, as something normal. The results of this work make us think that the public teacher needs to review his methods and educational processes; otherwise we are going to continue watching an educational system despondent and unconcerned about the development of criticizing skills on the process of reading learning in Junior High.

Aprender com os outros : uma estratégia para a inclusão de um aluno com Autismo

Este Projecto de Intervenção, “Aprender com os outros - uma estratégia para a inclusão de um aluno com autismo”, fundamentado nos pressupostos e nos procedimentos da investigação-acção, centrou-se nas acções em áreas de maior e menor sucesso do aluno, de nome fictício “Francisco”, no âmbito da língua portuguesa e da socialização, numa perspectiva inclusiva. Este aluno considerado com necessidades educativas especiais (NEE) apresentava perturbações do espectro do autismo (PEA), o que, à partida, se repercutia no seu défice de atenção, na autonomia para a realização das tarefas escolares, na área da linguagem e da comunicação e na interacção social. Como as interacções na turma e com a turma são essenciais para a aprendizagem, propusemo-nos implementar actividades específicas para o desenvolvimento das competências sociais e cognitivas, com abordagem comportamentalista, numa turma do 3º ano de escolaridade, onde estava incluído um aluno diagnosticado com PEA. Também procurámos desenvolver as suas competências académicas, através do trabalho realizado no grupo e com o grupo-turma, criando as condições que favorecessem a socialização do aluno e a sua autonomia. Para atingirmos aqueles objectivos, iniciámos um trabalho a pares e depois em pequenos grupos, para desta forma incluir o “Francisco” na dinâmica das aulas, para que participasse nas actividades propostas, obtendo o respeito dos colegas na valorização das suas intervenções e do seu ritmo de trabalho. Os objectivos definidos, bem como as actividades realizadas e avaliadas, implicando todos os intervenientes no processo, permitiram que o “Francisco” fizesse aprendizagens significativas nas áreas, académica, social, da autonomia e da comunicação. Segundo Silva (2009), a inclusão dos alunos considerados com necessidades educativas especiais no ensino regular implica mudanças ao nível das atitudes e das práticas pedagógicas de todos os intervenientes no processo ensino e aprendizagem, da organização e da gestão na sala de aula e na própria escola enquanto instituição. Acreditamos que só desta forma se pode proporcionar aos alunos marcados pela diferença, que é um valor em si mesma (Rodrigues, 2006; Leitão, 2006; Sanches & Teodoro, 2006; Silva, 2009), as mesmas experiências, aprendizagens e vivências que são proporcionadas aos restantes colegas.

Percursos e identidades. A (re)construção da identidade profissional do docente de enfermagem: o olhar dos docentes

RESUMO: Considerando a identidade como um processo dinâmico de interacção social, afastando-nos da ideia de identidades pré-estabelecidas, ancoradas numa visão essencialista e, aproximando-nos de uma identidade profissional que se constrói através de sucessivas interacções, procurámos conhecer a identidade profissional do docente de enfermagem. Convictos de que o estudo da identidade pode oscilar entre um pólo individual e um estrutural, optámos pela dimensão biográfica como eixo estruturante deste trabalho. Efectuaram-se oito biografias a docentes integrados no conceito de perito com uma profissionalidade reflectida. Utilizámos ainda o focus group como método complementar. Constatámos que os actores deste estudo se sentem enfermeiros, embora a sua área de actuação seja a docência. Destacam a integração do ensino de enfermagem no ensino superior como determinante na mudança da sua representação social. Todos estes docentes se incluem nos grupos que apresentam um estatuto da identidade realizado ou outorgado. Das competências que devem estar presentes no docente de enfermagem, salientam-se a comunicação, actualização científica e relação, capazes de promover um ambiente que propicie as aprendizagens significativas, de internacionalização, de investigação, como um modelo de conduta a seguir, que participe na vida da organização e seja capaz de motivar o outro, mas sobretudo que seja um bom enfermeiro. ABSTRACT: Considering identity as a social dynamic integration process, departing from the concept of pre-established identities anchored in an essentialist vision, and approaching a professional identity built trough successive interaction, we aimed to know the professional identity of the nursing teacher. Believing that the identity study may oscillate between an individual and a structural pole, we have chosen the biographic dimension as the structural axis for this assignment. Eight biographies from teachers integrated in the expert with a reflective professional identity have been made. We have also used the focus group as a complementary method. We have seen that the actors of this study feel themselves as nurses although their working area is teaching. They point out the higher teaching of Nursing as a determinant in the change of their social representation. All of these teachers are included in the groups that present an identity status that has been fulfilled or attributed. From the skills that should be present in the nursing teacher, communication, scientific knowledge and relationship are indicated when these are able to provide significant learning, internationalization and research as a behaviour model to be followed regarding the life of the organization and that might incentive others, but above as a way to be a good nurse.

Studies in search of a suitable experimental insect model for xenodiagnosis of hosts with Chagas' disease: 3 - On the interaction of vector species and parasite strain in the reaction of bugs to infection by Trypanosoma cruzi

The reaction of nine vector species of Chagas' disease to infection by seven different Trypanosoma cruzi strains; Berenice, Y, FL, CL, S. Felipe, Colombiana and Gávea, are examined and compared. On the basis of the insects' ability to establish and maintain the infection, vector species could be divided into two distinct groups which differ in their reaction to an acute infection by T. cruzi. While the proportion of positive bugs was found to be low in Triatoma infestans and Triatoma dimidiata it was high, ranging from 96.9% to 100% in the group of wild (Rhodnius neglectus, Triatoma rubrovaria)and essentially sylvatic vectors in process of adaptation to human dwellings, maintained under control following successful insecticidal elimination of Triatoma infestans (Panstrongylus megistus, Triatoma sordida and Triatoma pseudomaculata). An intermediate position is held by Triatoma brasiliensis and Rhodnius prolixus. This latter has been found to interchange between domestic and sylvatic environments. The most important finding is the strikingly good reaction between each species of the sylvatic bugs and practically all T. cruzi strains herein studied, thus indicating that the factors responsible for the excellent reaction of P.megistus to infection by Y strain, as previously reported also come into operation in the reaction of the same vector species to acute infections by five of the remaining T.cruzi strains. Comparison or data reported by other investigators with those herein described form the basis of the discussion of Dipetalogaster maximus as regards its superiority as a xenodiagnostic agent.

Equilibrium self-assembly of colloids with distinct interaction sites: Thermodynamics, percolation, and cluster distribution functions

We calculate the equilibrium thermodynamic properties, percolation threshold, and cluster distribution functions for a model of associating colloids, which consists of hard spherical particles having on their surfaces three short-ranged attractive sites (sticky spots) of two different types, A and B. The thermodynamic properties are calculated using Wertheim's perturbation theory of associating fluids. This also allows us to find the onset of self-assembly, which can be quantified by the maxima of the specific heat at constant volume. The percolation threshold is derived, under the no-loop assumption, for the correlated bond model: In all cases it is two percolated phases that become identical at a critical point, when one exists. Finally, the cluster size distributions are calculated by mapping the model onto an effective model, characterized by a-state-dependent-functionality (f) over bar and unique bonding probability (p) over bar. The mapping is based on the asymptotic limit of the cluster distributions functions of the generic model and the effective parameters are defined through the requirement that the equilibrium cluster distributions of the true and effective models have the same number-averaged and weight-averaged sizes at all densities and temperatures. We also study the model numerically in the case where BB interactions are missing. In this limit, AB bonds either provide branching between A-chains (Y-junctions) if epsilon(AB)/epsilon(AA) is small, or drive the formation of a hyperbranched polymer if epsilon(AB)/epsilon(AA) is large. We find that the theoretical predictions describe quite accurately the numerical data, especially in the region where Y-junctions are present. There is fairly good agreement between theoretical and numerical results both for the thermodynamic (number of bonds and phase coexistence) and the connectivity properties of the model (cluster size distributions and percolation locus).

Interaction of formaldehyde and tobacco smoking in the frequency of micronucleus and the XRCC3 Thr241Met polymorphism

Formaldehyde is classified by IARC as carcinogenic to humans (nasopharyngeal cancer). Tobacco smoke has been epidemiologically associated to a higher risk of development of cancer, especially in the oral cavity, larynx and lungs, as these are places of direct contact with many carcinogenic tobacco’s compounds. XRCC3 is involved in homologous recombination repair of cross-links and chromosomal double-strand breaks (Thr241Met polymorphism). The aim of the study is to determine whether there is an in vivo association between genetic polymorphism of the gene XRCC3 and the frequency of genotoxicity biomarkers in subjects exposed or not to formaldehyde and with or without tobacco consumption.

Percolation of colloids with distinct interaction sites

We generalize the Flory-Stockmayer theory of percolation to a model of associating (patchy) colloids, which consists of hard spherical particles, having on their surfaces f short-ranged-attractive sites of m different types. These sites can form bonds between particles and thus promote self-assembly. It is shown that the percolation threshold is given in terms of the eigenvalues of a m x m matrix, which describes the recursive relations for the number of bonded particles on the ith level of a cluster with no loops; percolation occurs when the largest of these eigenvalues equals unity. Expressions for the probability that a particle is not bonded to the giant cluster, for the average cluster size and the average size of a cluster to which a randomly chosen particle belongs, are also derived. Explicit results for these quantities are computed for the case f = 3 and m = 2. We show how these structural properties are related to the thermodynamics of the associating system by regarding bond formation as a (equilibrium) chemical reaction. This solution of the percolation problem, combined with Wertheim's thermodynamic first-order perturbation theory, allows the investigation of the interplay between phase behavior and cluster formation for general models of patchy colloids.

Effects of the interaction of tobacco smoke and alcohol consumption on buccal micronucleus in workers exposed occupationally to formaldehyde

Occupational exposure to formaldehyde (FA) has been shown to induce nasopharyngeal cancer and has been classified as carcinogenic to humans (group 1) on the basis of sufficient evidence in humans. Tobacco smoke has been associated to a higher risk of development of cancer, especially in the oral cavity, larynx and lungs, as these are places of direct contact with many carcinogenic tobacco’s compounds. Alcohol is a recognized agent that influence cells in a genotoxic form, been citied as a strong agent with potential in the development of carcinogenic lesions. Epidemiological evidence points to a strong synergistic effect between cigarette smoking and alcohol consumption in the induction of cancers in the oral cavity. Approximately 90% of human cancers originate from epithelial cells. Therefore, it could be argued that oral epithelial cells represent a preferred target site for early genotoxic events induced by carcinogenic agents entering the body via inhalation and ingestion. The MN assay in buccal cells was also used to study cancerous and precancerous lesions and to monitor the effects of a number of chemopreventive agents.
