Atenção, consciência e prática pedagógica: um estudo de suas interconexões

This thesis entitled, Attention, Consciousness and Practice of Teaching: A Study of its Interconnects, argues about a relationship between development of attention and consciousness and its connection to the pedagogical practice developed in a public elementary school in Natal city, Rio Grande do Norte state. The research school is located in the south of the city. School activities are developed according with the political pedagogical project. The group investigated was 25 students aged between 8-12 years of the fourth grade. The students of the research are residents of Ponta Negra village, Pirangi and Neópolis districts. The research was effected by three teachers however, the purpose of this thesis was to investigate the relationship between the development of attention and awareness and the pedagogical practice of one of the teachers who participated in the research, and more specifically understand the psychic procedures involved in the development of attention and awareness; enabling conditions for the realization of an educational action that enables the development in terms of focused attention and states of consciousness of students, analyzing their interrelations. Therefore, it was used as methodology the collaborative research by providing elements for research as strategy of formation and development, the coproduction of knowledge, and the change of educational practice through reflective processes effected through the collaboration and critical reflection among participants. For empirical construction, it was used the following procedural elements: meeting, planning, diagnosis of attention and awareness, reflective period studies, collaborative observation and reflection sessions with the participant teachers and the students. The diagnosis of attention was effected through a game and its elaboration was based on the study proposed by Luria (1991). The purpose of the game was to apprehend the stage where students were in relation of a development attention. Concerning the diagnosis of consciousness, it was taken as reference studies by Burlatski (1987), Pinto (1960a, 1960b), Rubinstien (1973), Leontiev (1978) and others studies discussing this topic. As a method of analysis, it was resorted to the dialectical historical materialism, the ability to identify, analyze and explain those contradictions generated in the process. In the analysis procedures were prepared some categories as well as, were used categories by other authors with the purpose of understanding the critical reflective process collaborative evidencing the formation of concepts and pedagogical practice of the participants, and the analysis of a practical pedagogical of a teacher and her relationships with the development of the psychic process and functions of students, in other words, attention and awareness. Regarding the reflective process were used the categories: technical reflection, critical reflection and practical reflection (LIBERALI, 2008). Concerning the analysis of the concepts were used the categories: description, characterization, definition and conceptualization (FERREIRA, 2003). And for critical collaboration were the categories: critical collaboration, uncritical, technique and practice. In pedagogical practice, were used categories: repetitive practice teaching, heterogeneous and reflexive critical (SOUZA, 2010). During the collaborative observation was evident predominance of heterogeneous practice, because the main participant teacher searches for immediate solution to the situations problem, as well as reflection moments, is the technical arrangement, practice, critical, as well as concern in interacting with students, the qualitative changes, deep knowledge, renewal and transformation of the teaching activity. In this process, the collaborative reflection proved to be an effective strategy for developing awareness of students, because through reflection sessions, the students were able to understand that learning is a building process and that it necessary to be careful for their development

On developing efficient applications using conservative distributed simulation paradigm

This paper aims to present, using a set of guidelines, how to apply the conservative distributed simulation paradigm (CMB protocol) to develop efficient applications. Using these guidelines, even a user with little experience on distributed simulation and computer architecture can have good performance on distributed simulations using conservative synchronization protocols for parallel processes.The set of guidelines is focus on a specific application domain, the performance evaluation of computer systems, considering models with coarse granularity and few logical processes and running over two platforms: parallel (high performance communication environment) and distributed (low performance communication environment).

Práticas de cidadania em narrativas de professores de ciências: trabalho coletivo de ensino e de aprendizagem

Esta investigação teve como contexto o município de Altamira, situado na região oeste do Estado do Pará. Foi realizada com professores de ciências de escolas públicas do ensino fundamental e teve como propósitos: i) identificar elementos presentes no fazer pedagógico de professores que afirmam vincular sua prática docente à aprendizagem para a formação da cidadania dos alunos; ii) compreender as razões que levam os educadores a desenvolver atividades com tal perspectiva. Trata-se de uma pesquisa qualitativa, na modalidade narrativa, utilizando como instrumento investigativo entrevista semi-estruturada na coleta dos relatos orais das professoras investigadas. As participantes da pesquisa revelam um ensino de ciências conectado com as demais áreas do conhecimento buscando apoio e participação da comunidade escolar. Destacam-se elementos da prática docente, tais como: i) Prática docente reflexiva, favorecendo a auto formação do profissional, por reconhecer seu fazer pedagógico como um ato de conhecimento e compreender sua importância política, ética, estética e também epistemológica. ii) Participação ativa em fóruns escolares, nos quais se planejam várias ações do processo educativo por meio de discussões de diferentes argumentos e troca de experiências. iii) Construção e execução de projetos temáticos que potencializam a alfabetização científica, por meio da exploração de ambientes socioambientais de ensino e de aprendizagem favorecendo a interação escola comunidade e a compreensão pública da ciência. iv) Democratização do espaço escolar, cuja utilização pela comunidade ocorre de diversas formas, dentre as quais se destacam a participação e socialização de atividades de ciências como: feira de ciências, jardinagem e horta escolar. v) Parceria, que se estabelece como meio de partilha de responsabilidade no ato de formar e de educar com o objetivo de estabelecer o diálogo entre a ciência e o senso comum. vi) Atitude como conteúdo expressa nas práticas dos professores que levam os alunos a tomadas de consciência e mudança de postura. vii) Solidariedade, um agir local que pode tomar maior dimensão, ato de reconhecer o outro como semelhante. viii) O cuidado no trato pedagógico, buscando caminhos para educar para além de sua disciplina ciências. Uma prática pedagógica estruturada sob a visão de ser humano que se indaga a respeito de seu lugar no mundo. Estes elementos permitiram a construção de três princípios educacionais pautados no aprender, uma vez que a intenção, da maioria das entrevistadas, ao ensinar ciências, se situa em dar condições intelectuais aos alunos para compreender processos naturais e tecnológicos presentes no mundo que os rodeia e comportarem-se nele como atores responsáveis.

New catalytic processes for the upgrading of furfural and 5-hydroxymethylfurfural to chemicals and fuels

The demand of energy, fuels and chemicals is increasing due to the strong growth of some countries in the developing world and the development of the world economy. Unfortunately, the general picture derived sparked an exponential increase in crude oil prices with a consequent increase of the chemical, by-products and energy, depleting the global market. Nowadays biomass are the most promising alternative to fossil fuels for the production of chemicals and fuels. In this work, the development of three different catalytic processes for the valorization of biomass-derived has been investigated. 5-hydroxymethylfurfural oxidation was studied under mild reaction condition using gold and gold/copper based catalysts synthetized from pre-formed nanoparticles and supported onto TiO2 and CeO2. The analysis conducted on catalysts showed the formation of alloys gold/copper and a strong synergistic effect between the two metals. For this reason the bimetallic catalysts supported on titania showed a higher catalytic activity respect to the monometallic catalysts. The process for the production of 2,5-bishydroxymethyl furan (BHMF) was also optimized by means the 5-hydroxymethylfurfural hydrogenation using the Shvo complex. Complete conversion of HMF was achieved working at 90 °C and 10 bar of hydrogen. The complex was found to be re-usable for at least three catalytic cycles without suffering any type of deactivation. Finally, the hydrogenation of furfural and HMF was carried out, developing the process of hydrogen transfer by using MgO as a catalyst and methanol as a hydrogen donor. Quantitative yields to alcohols have been achieved in a few hours working in mild condition: 160 °C and at autogenous pressure. The only by-products formed were light products such as CO, CO2 and CH4 (products derived from methanol transformation), easily separable from the reaction solution depressurizing the reactor.

Analysis and modelling of the performance of technologies for flue gas treatment in Waste-to-Energy processes

Waste management represents an important issue in our society and Waste-to-Energy incineration plants have been playing a significant role in the last decades, showing an increased importance in Europe. One of the main issues posed by waste combustion is the generation of air contaminants. Particular concern is present about acid gases, mainly hydrogen chloride and sulfur oxides, due to their potential impact on the environment and on human health. Therefore, in the present study the main available technological options for flue gas treatment were analyzed, focusing on dry treatment systems, which are increasingly applied in Municipal Solid Wastes (MSW) incinerators. An operational model was proposed to describe and optimize acid gas removal process. It was applied to an existing MSW incineration plant, where acid gases are neutralized in a two-stage dry treatment system. This process is based on the injection of powdered calcium hydroxide and sodium bicarbonate in reactors followed by fabric filters. HCl and SO2 conversions were expressed as a function of reactants flow rates, calculating model parameters from literature and plant data. The implementation in a software for process simulation allowed the identification of optimal operating conditions, taking into account the reactant feed rates, the amount of solid products and the recycle of the sorbent. Alternative configurations of the reference plant were also assessed. The applicability of the operational model was extended developing also a fundamental approach to the issue. A predictive model was developed, describing mass transfer and kinetic phenomena governing the acid gas neutralization with solid sorbents. The rate controlling steps were identified through the reproduction of literature data, allowing the description of acid gas removal in the case study analyzed. A laboratory device was also designed and started up to assess the required model parameters.

Membrane properties and synaptic integration of identified neuronal populations in the developing rodent neocortex

In my PhD work I concentrated on three elementary questions that are essential to understand the interactions between the different neuronal cell populations in the developing neocortex. The questions regarded the identity of Cajal-Retzius (CR) cells, the ubiquitous expression of glycine receptors in all major cell populations of the immature neocortex, and the role of taurine in the modulation of immature neocortical network activity.rnTo unravel whether CR cells of different ontogenetic origin have divergent functions I investigated the electrophysiological properties of YFP+ (derived from the septum and borders of the pallium) and YFP− CR cells (derived from other neocortical origins). This study demonstrated that the passive and active electrophysiological properties as well as features of GABAergic PSCs and glutamatergic currents are similar between both CR cell populations. These findings suggest that CR cells of different origins most probably support similar functions within the neuronal networks of the early postnatal cerebral cortex.rnTo elucidate whether glycine receptors are expressed in all major cell populations of the developing neocortex I analyzed the functional expression of glycine receptors on subplate (SP) cells. Activation of glycine receptors by glycine, -alanine and taurine elicited membrane responses that could be blocked by the selective glycinergic antagonist strychnine. Pharmacological experiments suggest that SP cells express functional heteromeric glycine receptors that do not contain 1 subunits. The activation of glycine receptors by glycine and taurine induced a membrane depolarization, which mediated excitatory effects. Considering the key role of SP cells in immature cortical networks and the development of thalamocortical connections, this glycinergic excitation may influence the properties of early cortical networks and the formation of cortical circuits.rnIn the third part of my project I demonstrated that tonic taurine application induced a massive increase in the frequency of PSCs. Based on their reversal potential and their pharmacological properties these taurine-induced PSCs are exclusively transmitted via GABAA receptors to the pyramidal neurons, while both GABAA and glycine receptors were implicated in the generation of the presynaptic activity. Accordingly, whole-cell and cell-attached recordings from genetically labeled interneurons revealed the expression of glycine and GABAA receptors, which mediated an excitatory action on these cells. These findings suggest that low taurine concentrations can tonically activate exclusively GABAergic networks. The activity level maintained by this GABAergic activity in the immature nervous system may contribute to network properties and can facilitate the activity dependent formation of adequate synaptic projections.rnIn summary, the results of my studies complemented the knowledge about neuronal interactions in the immature neocortex and improve our understanding of cellular processes that guide neuronal development and thus shape the brain.rn

Lateral spreading and associated slope processes in fractured rock slabs

Landslides of the lateral spreading type, involving brittle geological units overlying ductile terrains, are a common occurrence in the sandstone and limestone plateaux of the northern Apennines of Italy. These instability phenomena can become particularly risky, when historical towns and cultural heritage sites built on the top of them are endangered. Neverthless, the mechanisms controlling the developing of related instabilities, i.e. toppling and rock falls, at the edges of rock plateaux are not fully understood yet. In addition, the groundwater flow path developing at the contact between the more permeable units, i.e. the jointed rock slab, and the relatively impermeable clay-rich units have not been already studied in details, even if they may play a role in this kind of instability processes, acting as eventual predisposing and/or triggering factors. Field survey, Terrestrial Laser Scanner and Close Range Photogrammetry techniques, laboratory tests on the involved materials, hydrogeological monitoring and modelling, displacements evaluation and stability analysis through continuum and discontinuum numerical codes have been performed on the San Leo case study, with the aim to bring further insights for the understanding and the assessment of the slope processes taking place in this geological context. The current research permitted to relate the aquifer behaviour of the rocky slab to slope instability processes. The aquifer hosted in the fractured slab leads to the development of perennial and ephemeral springs at the contact between the two units. The related piping erosion phenomena, together with slope processes in the clay-shales led to the progressive undermining of the slab. The cliff becomes progressively unstable due to undermining and undergoes large-scale landslides due to fall or topple.

Intraflagellar transport in the developing and mature vertebrate retina

Intraflagellar transport (IFT) is required for the assembly and maintenance of cilia. In this study we analyzed the subcellular localization of IFT proteins in retinal cells by correlative high-resolution immunofluorescence and immunoelectron microscopy. The rod photoreceptor cell was used as a model system to analyze protein distribution in cilia. To date the expression of IFT proteins has been described in the ciliary region without deciphering the precise spatial and temporal subcellular localization of IFT proteins, which was the focus of my work. rnThe establishment of the pre-embedding immunoelectron method was an important first step for the present doctoral thesis. Results of this work reveal the differential localization of IFT20, IFT52, IFT57, IFT88, IFT140 in sub-ciliary compartments and also their presence in non-ciliary compartments of retinal photoreceptor cells. Furthermore, the localization of IFT20, IFT52 and IFT57 in dendritic processes of non-ciliated neurons indicates that IFT protein complexes also operate in non-ciliated cells and may participate in intracellular vesicle trafficking in eukaryotic cells in general.rnIn addition, we have investigated the involvement of IFT proteins in the ciliogenesis of vertebrate photoreceptor cilia. Electron microscopy analyses revealed six morphologically distinct stages. The first stages are characterized by electron dense centriolar satellites and a ciliary vesicle, while the formation of a ciliary shaft and of the light sensitive outer segment disks are features of the later stages. IFT proteins were expressed during all stages of photoreceptor cell development and found to be associated with the ciliary apparatus. In addition to the centriole and basal body IFT proteins are present in the photoreceptor cytoplasm, associated with centriolar satellites, post-Golgi vesicles and with the ciliary vesicle. Therewith the data provide an evidence for the involvement of IFT proteins during ciliogenesis, including the formation of the ciliary vesicle and the elongation of the primary cilium of photoreceptor cells. Moreover, the cytoplasmic localization of IFT proteins in the absence of a ciliary shaft in early stages of ciliogenesis indicates roles of IFT proteins beyond their well-established function for IFT in mature cilia and flagella. rn
