A educação a distância (EAD) é uma modalidade de ensino antiga que se renova com as novas tecnologias de informação e comunicação (NTIC). O momento presente é promissor para o desenvolvimento de pesquisas neste âmbito, visto o crescimento desta modalidade de ensino no Brasil. Universidades brasileiras (públicas, privadas, comunitárias e confessionais) têm investido em projetos de educação a distância; percebe-se que os modelos utilizados carecem precisão na configuração das funções exercidas pelos vários atores presentes na EAD. Por esta razão, o trabalho tutorial é pe squisado tendo como objetivo o desvelar das relações entre a formação do sujeito e o papel do professor tutor, considerando o Projeto Pedagógico Institucional e o projeto pedagógico dos cursos a distância, bem como suas proposituras sobre a concepção antropológica (homem), a concepção gnosiológica (conhecimento) e a concepção política (relações político-sociais). As hipóteses que sustentaram a pesquisa consideraram a tutoria como: mediadora no processo de construção do conhecimento e desenvolvimento do sujeito e como uma das responsáveis pela articulação da equipe de EAD, nas relações com o corpo discente, da Universidade Metodista de São Paulo. O texto, a seguir, é fruto do desejo de corroborar com o desenvolvimento desta modalidade de ensino no Brasil.(AU)

O século XXI trouxe profundas modificações na organização das sociedades e consequentemente no mundo do trabalho no âmbito da educação. O crescimento exponencial da dinâmica da comunicação nas sociedades possibilita a multiplicação generalizada de visões de mundo, a tecnologia é um agente de mudança e as inovações tecnológicas podem resultar em uma revolucionária quebra de paradigma educacional. Diante dos impasses de um mundo globalizado, em constante mutação cultural, surgem novas possibilidades de mediações que geram diferentes perspectivas para os processos educativos com a introdução das Tecnologias de Informação e Comunicação (TICs) e da Educação a Distância (EaD). Por esta razão, a Formação Docente é pesquisada tendo como objetivo analisar os impactos e as contribuições que as tecnologias trazem para este campo, especialmente no curso de Pedagogia, considerando uma experiência em EaD e sua relação com o curso na modalidade presencial a partir dos pressupostos norteadores do Projeto Pedagógico Institucional (PPI) na instituição pesquisada. Foi relevante perceber no decorrer da pesquisa bibliográfica e do estudo de campo que as duas modalidades apóiam-se na concepção de educação que está subjacente e que orienta as escolhas teórico-metodológicas adotadas pela instituição no seu PPI. A educação a distância possibilita a construção de um ambiente de aprendizagem mediado pelas TICs e novas compreensões sobre o processo de ensinar e aprender. O estudo mostra que a formação docente nesta modalidade deve estar articulada com o processo educativo e ter como eixo a concepção de um sujeito capaz de estabelecer novas formas de expressão e conhecimentos para trabalhar em uma educação do futuro. Portanto, é necessário pensar na Intencionalidade de sua formação, de modo a capacitá-lo com visão pedagógica crítica e objetivando que seja capaz de intervir no desenvolvimento educacional como um intelectual transformador.(AU)

Este estudo teve a intenção de analisar até que ponto o uso de diferentes bases de poder dos superiores hierárquicos predizem os níveis de engajamento no trabalho e de resiliência dos trabalhadores, colaborando para aumentar o conhecimento sobre o comportamento dos servidores públicos municipais, quanto aos níveis de engajamento no trabalho e resiliência apresentados. Partiu-se da definição de poder de French e Raven (1959): poder é a influência potencial que o agente O poderia causar no sujeito P; adotou-se o conceito de engajamento no trabalho de Schaufeli e Bakker (2003), que definem engajamento no trabalho como um construto motivacional positivo, caracterizado por vigor, dedicação e absorção, sempre relacionado ao trabalho, o qual implica sentimento de realização, envolve estado cognitivo positivo, é persistente no tempo, apresentando, assim, natureza motivacional e social e por fim utilizou-se o conceito de Grotberg (2005) que define resiliência como a capacidade humana para enfrentar, vencer e ser fortalecido ou transformado por experiências de adversidades . Para isto, definiu-se como objetivo geral testar a capacidade preditiva das bases de poder social dos chefes sobre a resiliência e o engajamento no trabalho, em servidores públicos municipais de Diadema - SP. Participaram deste estudo 95 servidores públicos municipais do município de Diadema, SP, com pequena maioria de indivíduos do sexo feminino (51,6%), com maior percentual de idade entre 25 e 40 anos (38,9%). A maioria dos participantes (60%) declarou possuir nível superior completo (35,8%) ou pós-graduação (24,2%). Utilizou-se os instrumentos: Escala de Bases de Poder do Supervisor (EBPS), escala desenvolvida por Martins e Guimarães (2007); Escala de Avaliação da Resiliência (EAR), escala construída por Martins, Siqueira e Emilio (2011) e a Escala de Engajamento no Trabalho de UTRECHT (UWES) que tiveram seus indicadores de validade e fidedignidade apurados neste estudo. Como resultado constatou-se parcialmente a existência de associação entre engajamento no trabalho e resiliência, pois engajamento no trabalho correlacionou-se com três dos cinco fatores de resiliência: adaptação positiva à mudanças, competência pessoal e persistência diante de dificuldade. Verificou-se que as dimensões que compõem a variável resiliência obtiveram médias ao redor do ponto quatro da escala de resiliência (frequentemente é verdade), indicando que os participantes frequentemente percebem a si mesmos como capazes de enfrentar as adversidades da vida em função da sua alta percepção de persistência, capazes de adaptar-se às mudanças, com bom nível de competência pessoal e de espiritualidade. Constatou-se que as médias nas dimensões que compõem a variável engajamento no trabalho ficaram muito próximas do ponto quatro da escala de engajamento (algumas vezes na semana), indicando que eles percebem em si um alto grau engajamento no trabalho, ou seja, que possuem vigor, são dedicados e deixam-se absorver pelo trabalho. Verificou-se ainda que os trabalhadores percebem o poder de perícia como o mais empregado pelos seus superiores hierárquicos com média de 4,46 (DP= 0,71). Por fim, os resultados obtidos apontaram que o papel e o posicionamento da chefia não provocaram impacto significativo em nenhuma das variáveis consequentes, portanto, bases de poder não explicam resiliência para os trabalhadores participantes desta pesquisa como também não predisseram engajamento no trabalho.

Passados quase dez anos de prática de atos correspondentes ao exercício profissional no âmbito da Agencia de Execução, pode-se com alguma legitimidade concluir acerca da grande responsabilidade em que se move o agente de execução. Atendendo a que este profissional se movimenta nos limites do direito fundamental à propriedade dos executados e dos exequentes, em constante e próximo relação com o Juiz do Tribunal, como legítimo e importante operador da justiça, levanta-se todos os dias a necessidade de definir como é que se há de demonstrar de forma rigorosa o registo fiável dos principais movimentos contabilísticos para explicar com clareza e transparência a conta-cliente. A conta-cliente é um espaço da total responsabilidade do agente de execução e é relativamente à qual ele tem de responder em caso de violação dos seus deveres deontológicos e contratuais. A indefinição que resulta da ausência de legislação e regulamentação eficaz ao nível da fiscalidade e do regime de prestação de contas da atividade do agente de execução coloca graves questões de segurança jurídica e de transparência. Por sua vez a Comissão para Eficácia de Execuções deve proceder à fiscalização prévia da atividade do agente de execução, e esta tarefa está irremediavelmente hipotecada enquanto não houver um modelo contabilístico que permita de imediato dar a conhecer todos os seus movimentos da conta-cliente de forma a dar um plano real dos processos/ações executivas/clientes e as fases em que os mesmos estão. Procurar este relatório imediato como uma fotografia em tempo real da situação dos processos em mãos e do volume de negócio do escritório foi motivação suficiente para encontrar uma solução para este problema, que em rigor é um problema que o legislador deixou em aberto, porque não resolveu a questão do que entende por “dispor de contabilidade organizada obrigatória” deixando que o profissional das ações executivas preenchesse essa lacuna no dia-a-dia, através de uma gestão doméstica da sua atividade.

Prospecting pharmacological active polysaccharides from agricultural byproducts, such as corncobs, is an underexplored practice in the scientific community. Thus, this work aims to expand knowledge about pharmacological activities of polysaccharides extracted from corncobs. From corn cob flour a extract was obtained by ultrasound waves in an alkaline medium, and the end of the process the product was termed PECC (polysaccharidic extract from corncobs). This extract was physicochemical characterized and evaluated by in vitro assays as an antioxidant, cytotoxic, anticoagulant and imunomodulator agent. Results indicated significant activity metal chelating by PECC, and the use of PECC in cell culture cells showed no toxic effects to normal cell lines, but toxic action against HeLa tumor cells due promoting cell death by apoptosis. In addition, other pharmacological effects were observed, the PECC decreased nitric oxide (NO) production by activated macrophages, and prolonged blood clotting time through APTT assay. Then methanolic, ethanolic and ketone fractions were obtained from fractionation of PECC polysaccharides. Five methanolic fractions, six ethanolic fractions and two ketones were obtained; and all fractions were evaluated for antioxidant, cytotoxic, anticoagulant, immunomodulatory activities. E1.4 fraction exhibited significant metal chelating effect, a toxic action to induce apoptosis in HeLa cells, decreased NO production by activated macrophages, and extended blood clotting time. These results showed that the PECC pharmacological active polysaccharides would be present in the fraction E1.4. From fractionation of E1.4 polysaccharide six subfractions with different sizes were obtained: <3; 3-10; 10-30; 30-50; 50-100 and >100 KDa. About 80% of E1.4 polysaccharides had lower size to 10 KDa, and all the subfractions showed over 61% sugar in their chemical compositions. These subfractions exhibited different monosaccharide compositions, but xylose was presented in all of them. The subfractions exhibited distinct pharmacological effects in in vitro assays. Smaller subfractions (<30 KDa) had highest metal chelating activity and greater toxic action in tumor cells. The intermediate fractions (between 30-100 KDa) decreased more NO production of activated macrophages, for other side, the larger size (>100 KDa) modulated a greater number of inflammatory cytokines, and the had greatest anticoagulant effect. Therefore, when analyzing all the results together it is evident that the PECC pharmacological polysaccharides are heteroxylans, and were concentrated in E1.4 fraction, and heteroxilanas pharmacological effects depends on their molecular size. Thus, corncobs could be used as source from molecules with biotechnology potential

Caffeine is the most consumed psychostimulant, with effects on attention, memory, and arousal. But when this substance is ingested near to bedtime there is a decrease on sleep, interfering on mnemonic processes. So, our ain was to investigate how the caffeine ingested near to sleep onset acts on sleep and memory in marmosets. We used 16 adult marmosets, single housed, in a 12:12h light-dark cycle. For registering locomotor activity were used two kinds of sensors. The gyroscope sensor registers activity each 30 sec and detects motion with good accuracy. Because of this we used this sensor for detecting nocturnal activity. The second sensor was based on infrared and accumulates activity each 5 min and it’s not able to detect nocturnal activity, just diurnal activity. We also used camera for registering Rest phase of one marmoset. For the cognitive task, the animals needed to learn a rewarded context (CR) when compared to a non-rewarded context CNR). This experiment comprises 5 phases: 1) Two days of habituation to apparatus; 2)Training for 8 days; 3) oral administration of caffeine (10 mg/kg) or placebo administration ±1h before sleep onset, for 8 days, with marmosets receiving placebo or caffeine; 4) retraining to apparatus and after that, placebo administration (placebo group-GP), or caffeine administration (with continuous group-GC and acute groupGA); 5) Test, for evaluating learning to CR. The sessions were filmed and each one had 8 min of duration. At 7 am started the habituation, training and test sessions, and at 3:15 pm started retraining. The results for gyroscope sensor showed that there was coincidence of 68,57% with nocturnal register of the cameras. Then, the gyroscope sensors detected nocturnal activity for all experimental groups Moreover, when compared sensor gyroscope with sensor based on infrared, was observed that both sensor presented similarity on patterns of activity curve. When we observed the effects of caffeine on Activity-Rest Cycle in GP, GA and GC, is possible to see that that gyroscope sensors and based on infrared presented only intra group differences. As behavioral results, the marmosets learned to discriminate CR when compared to CNR. Moreover, GP presented deficits on memory recall during the test, and GA increased the memory recall, when both were compared to GP. We concluded that the marmosets were able to learning the cognitive task and that the caffeine ingested near to sleep onset acts modulating memory in these animals. Moreover the gyroscope sensor can be used as alternative tool for investigating nocturnal activity. Then, the utilization of this non-invasive device allows marmosets exhibit their behavior within the laboratory conditions as natural as possible.

In this dissertation, under the light of a sociofunctionalist approach (TAVARES, 2003; 2013; GORSKI; TAVARES, 2013), I analyze 378 data of pronouns tu and você extracted from 12 conversations belonging to Natal Conversational Data Base (CUNHA, 2010). I have the following objectives: (i) mapping linguistic and extralinguistic specialization trends of second person singular subject pronouns tu and você in the speech of Natal (RN); (ii) assessing the role of the principle of persistence (HOPPER, 1991) as a possible motivating factor of specialization trends of pronouns tu and você; (iii) identify in which of the six pronouns subsystems proposed by Scherre et al. (2009) is situated the speech community of Natal portrayed in this study. In order to achieve the proposed objectives, I submitted the data to multivariate statistical analysis, which have provided frequencies and relative weights.I obtained, as relevant factor groups, according to the statistical analysis, the nature of the relationship between the interlocutors (if the relationship is asymmetric, less intimate, and more formal, the use of você is favored; if the relationship is symmetrical, intimate and informal, the use of tu is favored); the degree of formality of the environment in which the conversation takes place (in more informal environments tu was favored; in more formal environments você were favored); and the type of discourse (reported / not reported) (tu was favored in not reported discourse and você was favored in reported discourse). Based on results regarding to these factors groups, I organized a panorama of specializations of pronouns tu and você, noting that tu seems specialized for more informal contexts of use than those for which você seems specialized. The motivation underlying these trends of specialization may be the principle of persistence, since along its historical development, você carries a trace of greater formality or, at least, less intimacy, when contrasted to tu. Finally, I concluded that, of the six pronoun subsystems proposed by Scherre et al. (2009), the speech community of Natal can be framed in the fifth, characterized by variable use of subject pronouns tu and você, with more frequent use of você than tu, and rare occurrence of agreement of tu with second-person singular verb.

This thesis examines the medial construction of the Portuguese of Brazil (PB). It is a construction which describes a causative event in which a non-human subject participant is affected by an action that does not originate from itself. Thus, we are interested in investigating this type of construction, its specific characteristics, motivations and discursive context from its semantic- cognitive and discoursive - pragmatic functions. The research questions are: what is the prototypical structural configuration of the medial construction (MC) in the Portuguese of Brazil? What are its specific discoursive functions? What is the degree of MC transitivity based on the properties proposed by Hopper and Thompson (1980)? We assume that the medial construction has its own structure which particularizes its significant dimension, thus ensuring a certain distance between the one in charge of the event and the affected entity. The theoretical and methodological assumptions is founded on Usage-based Functional Linguistics (FURTADO DA CUNHA; BISPO; SILVA, 2013). It is a research of qualitative- interpretative nature that has prioritized the analysis of occurrences arising from texts produced by users of the Brazilian Portuguese language in effective communicative situation. The database for this study is electronic texts available on the website www.reclameaqui.com.br. The results revealed the existence of different configurations of the medial construction in the Brazilian Portuguese, having as prototypical the one formed by SN + V. From the morphosyntactic and semantic point of view, the construction expresses a subject affected by an action that does not part from itself. As for the pragmatic aspect, the construction expresses an event that seems to have the purpose to emphasize the affected argument and to ignore, intentionally or not, the agent or the causative, since it is irrelevant to the speaker/ listener in the contextual situation.

As we are aware, the classroom is emerging as a continuous build learning experiences and environment, however, for students also it functions as a place also to be due to socializing with friends. However, not always these elements complement each other, so as harmoniously as we are aware that there are many difficulties, both in the act of learning as in interpersonal relations between them. From this, we understand that it is for the school to seek ways to contemplate such issues so that they feel inserted both with regard to this learning as well as being able to interact with themselves and with others, in a participatory manner, to live well socially. Thus, we find ourselves facing a similar situation with a 9th grade class where the students had certain limitations to have a good relationship with one another, causing thus problems in learning. On the other hand, this difficulty as affectively interact with each other, also, was increased by the difficulty that some students had to speak for themselves and to show their feelings and emotions, getting even more difficult this interaction at school. Thus, we found ourselves obliged to act immediately and need to bring about change in this picture. So it came out the idea of the application of an intervening action which started taking shapefrom a pedagogical project that we developed in other classes in previous years, this time adapted to the situation experienced by the group. The project, framed in the qualitative research and characterized from the action research approach took shape, and elected as its main objective to seek possible alternatives to develop the communicative competence of students, which is why we invest in exercise oral communication (speaking and listening) in order to promote the use of language, the interpersonal involvement facilitating thus their participation both in the classroom and in social life. To fulfill this goal, we set out to develop a didactic book whose support materialized through the autobiographical narrative (molded in writing production) and worked along a structured instructional sequence in three distinctstages that dialogued with each other. Therefore, we base our study from the socio-historical conception and dialogue proposed by Bakhtin in line with the sociodiscursivo interactionism of Bronckart and resort to other scholars as Dolz and Schneuwly, Marcuschi among others. The development of all stages of the project not only has had an immediate effect on what we proposed ourselves as also yielded us very gratifying moments reinforcing to us that the classroom environment goes far beyond the fact ministering content. And that work with orality, with views on affective interaction of these students resulted in a project, so to speak, exciting.

Assuming the body as a space of communication and production of subjectivity, we investigate, through the perspective of the contemporary youth at UFRN, the complexity surrounding the act of adorning the body as an act of communication, more precisely a visual communication, filled with symbolism and personality. Using the metaporic method, we seek to follow the communicational act, resulting from the relationship between these unique individuals at UFRN, their adornments and clothing, as an act that produces meaning. Through these narratives and singular expression, observed in these adorned / dressed bodys, we were able to identify seven categories that outlines the collage-individual that we present here: Aesthetic inconsistency and frequent change of style, gender X clothes, spaces regulated by a dominant aesthetic, symbolic connection with garments and / or accessories, the building an authorial image through various aesthetic references, moment of aesthetic rupture with socially established standards, and, parts of the body whose modification or acceptance reflects aesthetic ruptures.

La tesi esplora le problematiche relative all'integrazione di tecnologie per lo sviluppo di sistemi multi-agente e tecnologie per lo sviluppo di sistemi di comunicazione ad eventi. In particolare è stata posta l'attenzione sui concetti condivisi da entrambe le tecnologie e su come sia possibile realizzare l'integrazione preservando i principi fondamentali delle due tipologie di sistemi, tramite l'implementazione di un'astrazione di coordinazione oggettiva. Inoltre viene mostrato un esempio di integrazione tra JADE, TuCSoN e Kafka, tramite un caso di studio che permette di utilizzare i tre modelli di coordinazione offerti da questi framework in un unico sistema multi-agente.

Many changes have taken place in contemporary society causing impacts in its different sectors, making it much more complex and insecure than in past times. The alteration on the decision-making system of the Brazilian society is among the main changes today. The post-modern context contributed to the occurrence of the transfer of state power of the Legislative and Executive Powers to the Judiciary Power, specifically to the Federal Court of Justice, leading to an expansion on the actuation range of this institution mainly through the exercise of the constitutional jurisdiction. This has caused a crisis of legitimacy in society once the Court will now decide the political and social fundamental issues. In this scenario, the Direct Action of Unconstitutionality n° 3937/SP and n° 3357/RS are highlighted and both are being tried by the Supreme Court. Such emphasis is given, since it is a matter of high complexity and social repercussion that will be decided by a legal institution and not a political one. Thus, this work aims to analyze the role of the Supreme Court in the context of contemporary society on the trial of complex and controversial cases, particularly on the trial of Direct Action of Unconstitutionality n° 3937/SP and n° 3357/RS. This study has noticed that due to the post-modern context the majority of the Supreme Court Ministers tend to base their votes in constitutional principles and no longer limit themselves to a formal review of the constitutionality of laws, which indicates a substantialist approach. Moreover, it can be noticed the deliberative potential of the Court as well as the influence of the post-modern features, such as risk, uncertainty and insecurity on the elaboration of the Minister‟s votes. Therefore, sometimes, such as the case in study, the Supreme Court has acted as a technocratic agent in Brazilian society once fundamental political and social decisions for society especially when it comes to complex and controversial cases are being taken by the Supreme Court, which is composed by “Law technicians” and such decisions are mainly based in technical data and scientific studies. For the accomplishment of this work, it has been adopted the inductive approach and monographic procedure method and the bibliographical and documentary research technique.
