Tout au long de l Histoire l émergence des formes juridiques révèle que le Droit en tant qu espace de conflit discoursif institutionalisé n est ni supra-social ni naturel. Il est plutôt le résultat de relations de lutte et de pouvoir. L exercice du discours juridique recèle ainsi une forme politique de maîtrise du langage et du pouvoir créant des effets de vérité à travers l opération argumentative. Devant ce cadre et à partir de la matérialité du discours, la présente recherche vise à étudier la constituition de l ethos tant que procédé institutionel ayant pour but la construction d effets de vérité dans le procès juridique. Pour que ces procédés soient analysés on considère que les acteurs se constituent par leur langage, celui qui sera altéré à la fois par des stratégies discoursives. En prenant comme référence le concept d ethos et en utilisant comme corpus d analyse les procès-verbaux d un cas d homicide dont l agent est la mère de l aggresseur sexuel de son fils, cette étude vise de comprendre la construction des images de personnages concernés par les procès lors des divers témoignages au jury. Pour cela la méthodologie y employée s appuie sur les concepts d acteur et de pouvoir établi par Michel Foucault autant que celui d ethos, proposé par Dominique Maingueneau. Ayant l expectative d aboutir à démarquer les procédés de la constituition d effets de vérité et les relations de pouvoir dans une situation de dispute entre les paroles où on cherche à légitimer ses objectifs communicatifs, le travail a pour but de réfléchir à propos de la constituition du savoir juridique en tant que pratique discoursive capable d établir les différences parmi les individus grâce aux relations de pouvoir historiquement construites.

This work analyses the organizational arrangement isomorphism of graduation course coordination of the university center institutional model. This model has been regulated in the higher education since 1996 with the new Law of Guidelines and Basis of Education (Lei de Diretrizes e Bases da Educação). Taking into account that the educational institutions submit to the authoritative force of the legislation determined by the Educational Ministry, the course was taken as a referential to describe the structure framing facing the legal demands. This is the main focus of preoccupation of the university center because it is through this framing that teaching is transmitted. To achieve the target of this work a bibliographical research has been carried out on the institutional theory, on the new institutionalism and on bureaucracy characteristics and types of organizational structures. In addition to it, a case study has also been carried out with the courses of Administration and Social Communication Publicity and Advertisement in four university centers (three private institutions and one public institution) in the country of São Paulo State. One chairperson of each institution was interviewed, as well as the coordinators of the courses above mentioned, in a total of twelve researches. The isomorphism of the organizational arrangement in the graduation course coordination has been identified specially on the issues pre-established by law. Comparing the same courses, it has been observed that the courses of Administration are more isomorphic than the courses of Social Communication Publicity and Advertisement. Besides, a flexibility trend of the organizational structure of the institutions has been verified and this is meant to conform to the environmental uncertainties, that is to say, the existence of a mechanical structure (inheritance of the departmental framing) together with an organic structure. This factor also reflects on the difference between the form of course management where coordinators under the same internal regimen orientation print on the course their identity and their way of managing.

Farfantepenaeus paulensis, also known as pink shrimp, is a shrimp species usually found from Ilhéus (Bahia, Brazil) to Mar Del Plata (Argentina) and represents an important employment source for many Brazilian fisher s families. The study of its population structure using morphometrical parameters and microsatellites markers may provide basis for conservation programs. The purpose of this study is to analyze the population structure of pink shrimp F. paulensis at the Brazilian coast, in the south and southeast regions, using microsatellite markers and its morphometrical parameters. The shrimps were sampled in Patos Lagoon (RS), St. Antônio Lagoon (SC), Itajaí-Açu River (SC), Babitonga Bay (SC) and Cananéia City (SP). Although univariate and multivariate morphometric analyses had shown different population structure degrees between the studied places, the results of both microsatellites markers and multivariate morphometric analyses showed the possibility of the occurrence of four F. paulensis populations. The results of this study are of great value to the development of future programs for the conservation of this species, so that this resource is not depleted by over-fishing, fishing activity guaranteed to the current generation and future generations.

In the Quantum Optics area, the construction of effective hamiltonian is a matter of great importance, since from them we can generate and manipulate quantum states and logical operations. In this work we discuss 3 approximate methods for obtaining such effective hamiltonians: i) adiabatic elimination, ii) method of effective dynamics for oscillating hamiltonians and iii) nonlinear small rotations. Here we analyze the regime of validity of these techniques, their disadvantages and advantages. We note that, although adiabatic elimination is the most used and known, it has inconsistencies and can provide incorrect effective hamiltonians. The method of effective dynamics, although a very simple technique, also has inconsistencies and is not applicable to dissipative systems. Moreover, the method of nonlinear small rotations, which appears as the most accurate, is rarely used in the literature.

Data collected allowed the development of two studies, their objects are: Study I compare the physical performance, cardiovascular and respiratory responses, and the sensation of dyspnea (BorgDyspnea) and fatigue and pain in the lower limbs (BorgLL) between asthmatic and healthy adolescents in the six minute walking test (6MWT) and six minute step test (6MST); and determine the influence of body mass index (BMI), physical activity level (PAL) and spirometric variables in physical performance and responses obtained in the tests. Study II verify whether in 6MST there is a correlation between quality of life (QOL) in adolescents with asthma and the following variables: physical performance, cardiorespiratory responses, BorgDyspnea, BorgLL, spirometric responses. Also, whether there is a correlation between QOL and the PAL of these individuals. For this, 19 adolescents with asthma (AG) and 19 healthy (HG), aged between 11-15 years, both sexes, were assessed by spirometry, by 6MWT and by 6MST, and their PAL were quantified by International Physical Activity Questionnairy (IPAQ). The asthmatics answered the Pediatric Asthma Quality of Life Questionnaire (PAQLQ). In the Study I, in the 6MST, lower performance (6MST-T), lower heart rate (HR) and higher BorgLL were observed in AG. In the 6MWT, the walking distance (WD) was positively correlated with PAL, and HR with BMI in the AG; and in the HG, the HR and respiratory rate (RR) were positively correlated with WD. In the 6MST, in the AG, HR and RR were positively correlated with spirometric variables, and the PAL with 6MST-T. The 6MST-T was negatively correlated with BMI, and BorgDyspnea with PAL. In the HG, the HR and RR were positively correlated with spirometric variables; and the BMI with BorgLL. In Study II, negative correlations were obtained between BorgDypnea and total score of the questionnaire (PAQLQ-T); and BorgDyspnea and BorgLL with symptoms domain (St) and limitation in activities domain (LA). They were observed positive correlations between PAL and PAQLQ-T, LA and St. In the regression analysis, for PAQLQ-T and LA just BorgDyspnea was significantly in predicted them; and for St just BorgLL. Concluded that the 6MST was capable to detect the limitations of adolescents with asthma in activities of moderate intensity, because the AG showed lower physical performance and higher BorgLL in relation to HG. The spirometric variables, the BMI and the PAL influenced the responses obtained in the tests. Also, the higher PAL and lower BorgDyspnea and BorgLL in 6MST better quality of life. The 6MST has to be an option for evaluating exercise capacity in these asthamatics, because it reflects the discomfort caused by asthma, due to their symptoms, in the practice of physical activities of daily living.

The present study aims to analyze the representations of future in four science fiction movies launched at random during the past thirty years. Blade Runner,by Ridley Scott, Artificial Intelligence, by Steven Spilberg, Idiocracy, by Mike Judge and Children of Men by Alfonso Cuarón, compose our selected corpus for discussion and dialogue. For that purpose, we some concepts have been borrowed as Memory of Future, Dialogism and Intertextuality. The first science fiction film placed in the future we have ever seen was Terminator and the war between Humans and Machines. The child´s innocence made us count the days for the fatidic 1997, but there was no background to feel the film was reconstructing the present of that time, the Reagan era and his technological pyrotechnics war. If each era represents the future according to its own contradictions, in these movies the dialogues are marked above all by political, ideological and even existential ruptures. On the selected movies the world is always in transformation, reflecting the contexts of their times. Another goal of this thesis is to reflect upon the transposition process of literary tradition texts to the motion pictures language aiming the work production to the great audience via movie- theaters and television. At last there is an intent to contribute to the language and cultural studies, applied to the science fiction movies, and leave something relevant about the filmic representations of the future presented on movie-theaters screens.

This work seeks to identify and analyze the quality management forms adopted by two engine assemblers and by nine of their first and second tier suppliers, discussing the relationships between the quality management form implemented by each assembler and the ones implemented by its suppliers in each supply chain studied. In a second moment, this work compares the two sets of quality management forms adopted in those two supply chains. Three hypotheses orient this research: the two engine assemblers adopt different quality management forms; the suppliers of those engine assemblers adopt different quality management forms as well; the two sets of quality management forms adopted in those supply chains are different, since the distinct quality management forms implemented by the assemblers and by their respective suppliers are conditioned by different supply chain structures and relationships. This work is accomplished through some literature revisions on the topics associated to the mentioned subject and secondly through a field research that involves case studies carried out in two supply chains. These two supply chains have different configurations: they are headed by two engine assemblers that present distinct levels of vertical integration and have different types of relationships with their respective suppliers. In each one of the analyzed companies two engine assemblers and nine suppliers (from the first and the second tiers) some semi-structured interviews were realized. The results indicate that the quality management forms implemented by the two engine assemblers are very similar. They indicate as well that the adoption of the conception main principles and guidelines of the Total Quality Management by all suppliers assures certain resemblance amongst the quality management forms implemented by them. But there are indications that the adopted forms by the suppliers are different, being the most sophisticated practices implemented by the multinational suppliers. It is observed an association between the differences in the supply chain structures and relationships and the differences in the two sets of quality management forms adopted (in the two chains). The supply chain in that the assembler has a higher degree of outsourcing and a bigger proportion (and absolute number) of smaller and national capital suppliers, with the goal of having cost advantages (with lower prices and lower transport costs), must, in compensation, spend bigger effort to guarantee the quality of the components it acquires. The chains characterized by engine assemblers having fewer suppliers are usually noticeable by long term relationships, with a greater number of large-sized suppliers, more technologically capable (generally multinationals companies certified according to quality standards), must make a relatively bigger effort to negotiate with suppliers, but a much lower effort to develop them.

The project process is critical so that be achieved the objectives of quality for constructive prefabricated concrete. The correct development of a project process, from the program systematization of quality management, promote to the efficacy of the entire production project. Thus, this dissertation has the objective to propose guidelines for effective implementation of project requirements established by section 7.3 and others sections related to the project process, referenced in standard NBR ISO 9001:2000 to manufacture companies of prefabricated concrete. These guidelines were established from the review of literature and of the explorative case study, accomplished in three manufacture companies of prefabricated concrete, where through a preliminary questionnaire and observation, we can collect data that identify the attention points for quality management of process project. To achieve the objectives above, were investigated aspects such as: the project relevance to the concrete prefabs industry, the method of project coordination in prefab and the impact of non-conformance projects for the production process (production and setting prefabricated project).

The present work has as objective socialize the discussions that resulted in the present master dissertation, performed in the Post-graduation Program in Education, of the Universidade Federal de São Carlos UFSCar in the "Teaching Methodology" area, in the "Teaching and Learning Process in different contexts" research line, being integrant part of the investigative jobs that have been performed by the Writing and Reading Acquisition: teaching and learning process research Group. In the second semester of 2007, it was offered to the teachers of different schools - public and private - in the city of São Carlos a course of extension named Literacy: Reflections on the knowledge in the first year of the Fundamental Teaching - PROEX/UFSCar, having as one of the goals argue about evaluative processes for the first year of the Fundamental Teaching, with duration of nine years. Thus, we seek to investigate how to configure descriptors and criteria set that form some evaluative instruments collectively built, for the native language acquisition process comprehension. Going through the "Collaborative Methodology" presuppose, the main goal of this research centered in elaborate evaluative instruments , starting from a work collaborative among teachers, research partners, and researchers, boarding the conceptions on evaluation of the participants, the characteristics that they attributed to the evaluative instruments and the implications that such instruments would bring to the educational intervention process . The discussions in studies group and the speeches recordings transcriptions were used as procedures for data collection. The studies on evaluation and some School concepts of Vigotski carried us to reflect about the transformations possibilities in the teaching and learning processes concerned to the evaluation and to the learning levels attribution referring to the literacy process. We left of the principle that clearness and systematization lack of the evaluative process turns it somewhat superficial. With this research we verified that we cannot disregard the importance of evaluative instruments systematization, once it can be a mechanism able to signal to the teacher the students needs that, this way, will be able to plan and to guide his intervention work and his teaching activities. This work provided reflexive activities on the configuration and on evaluative activities elaboration that carried us to a better acquisition process comprehension of the reading and of the writing, indispensable for the possible planning of the educational action. Finally, the result of this study served of guide to base the planning and the research action that integrates the project Learning Communities: it bets on learning quality, in the differences equality and in school administration democratization , financed by the FAPESP and by CNPq, inserted in the axis: Reading and Writing learning .

Treating the rights related to persons with special needs (PSN) is a matter not only to professionals in the area of Law, but to society as a whole. Knowledge of legislation with the resulting disclosure of such information, will bring benefits not only to their own people with such needs and their families, but also contribute to the improvement of professionals with whom they are related. In the survey, the main objective was to identify the informational needs of lawyers into law on the rights of persons with special needs (PSN). The survey characterized as being kind of exploratory and descriptive and analysis of the curriculum of the Law courses offered in the State of São Paulo. The methodological procedures involved the following steps: a) review of literature related to matters under consideration, that is, rights of PSN, Special Education and Information Science, for reasons of theoretical research; b) review of literature about the legislation targeted specifically at PSN considering it is the law of Brazil; c) analysis of the curriculum of the Law courses offered in the State of São Paulo to verity the existence of specific material regarding the rights of persons with special needs; d) organization and systematization of data, with a view to examining which will be done will be done in the light of theoretical reference; e)elaborate a proposal of specific material regarding the rights of persons with special needs to Law courses. At the end of the survey aims to: contribute to guaranteeing the rights of persons with special needs; promote integration between the areas of Information Science, Law and Special Education, seeking the production of knowledge qualified to help the lawyers a right to act in defense of the rights of persons with special needs.

Parental involvement can be crucial for children s academic success; however, parents often don t have appropriate repertoire to deal with scholar difficulties or to promote autonomous and effective study behaviors in their children. The purpose of this study is to develop and evaluate an intervention program with children s guardians, particularly of those children with a history of low school performance. Participated in the research three guardians of children (two mothers and one grandfather), indicated by teachers as having learning difficulties, which were submitted to the Teaching Program, and also the teachers and the children, who studied at a municipal elementary school in a small town of the state of São Paulo. Initially, information was collected in order to determine the starting repertoire of the apprentices in the teaching program, through interviews with the children, their parents and teachers. The Teaching Program consisted of eight meetings in which was presented information and examples of aspects that promote the behavior of studying at home, in addition to several exercises for evaluation of performance and homework proposals regarding the themes discussed in the program. The parents received an instructional material to help with the explanation of teaching units and suggested activities. Due to holidays in the end of the school year, the intervention meetings were interrupted after the fourth session, but resumed in 60 days. On resumption, the parents were re-interviewed and responded to questions of true or false, concerning the units discussed up to that moment. Teachers, who had finished the school year, were also submitted to an interview. After the completion of the Teaching Program, information was collected as measures of post-test through interviews with parents, children and teachers of the new school year. In addition to the interview, the parents answered a questionnaire of satisfaction about the Teaching Program and a general simulation exercise. A follow-up interview was conducted six months after the post-test, again with the parents, teachers and children, and the parents also went through a new simulation for performance verification. The results show that the program enables the identification of changes in the repertoire of the parents in dealing with the children s study and/or the daily routine of interaction in the family environment, especially for one of the three participants in the period between the pre and post-test. Little evidence of maintenance of these changes was observed in the follow-up interviews. Some indication of improvement in the behavior of study and school performance of children, even minor, could also be identified in the teachers report. The discussion highlights the variables that may be important to understand these results and to advance in the creation of strategies for development, implementation and evaluation of Teaching Programs that are effective for teaching parents to promote appropriate study behaviors in children in order to promote appropriate study repertoires, as well as overcome and prevent school failure.

TS-FF-AAS employs a metal tube atomizer above an air/acetylene flame and in this case, the atoms residence time is longer than that observed in FAAS (Flame AAS). As a result, elevated background signals are obtained. For this reason, a study about the effects of the concomitants Ca, Cu, Fe, K, Mg, Mn, Na and Zn on the analytical signals of Cd and Pb with the help of factorial design was performed initially. Cadmium and Pb analytical signals were not significantly affected by the presence of concomitants. Although, the main purpose of this study was to make use of background signals and multivariate calibration as a procedure to assess the total concentration of concomitants in Thermospray Flame Furnace Atomic Absorption Spectrometry (TS-FF-AAS). Background signals of 29 solutions containing Cd (25 g/L), Pb (500 g/L) and four concomitants (Ca, K, Mg and Na – total concentration values ranging from 0 to 5.52 g/L) were recorded at two wavelengths: 228.8 Cd and 283.3 nm Pb. With the help of Partial Least Squares (PLS), calibration models using either each wavelength alone or a combination of both were constructed to predict the total concentration of concomitants. The best model showed Root Means Square Errors of Validation (RMSEV) of 0.35 g/L using background signals at 283.3 nm. A pharmaceutical sample containing 3 g/L (sum of Ca, K, Mg and Na) was analyzed and 3% was the relative error. This sample and those used in the calibration and validation sets were also analyzed using X-ray fluorescence (XRF) and a good agreement was observed. This study extends the possibilities for the use of background signals in spectrometric techniques.

Despite the intense mechanization that has taken place over recent years, manual material handling still takes place in most occupational environments. Gripping loads have been related with musculoskeletal disorders, but few studies evaluating upper-limb movements by means of direct measurements in occupational environments are available in the literature. The aim of the present study was to describe the types of grip adopted during handling boxes at different heights on industrial pallets, and to record the wrist, forearm and elbow movements. Electrogoniometry was used to record the movements of seven experienced workers during a real activity in an occupational environment. Most of the workers positioned their hands on the load asymmetrically, and the box handles were not used. Large elbow movements and extreme amplitudes of wrist extension and radial deviation were observed according to the different types of grip. The Kruskal-Wallis and post-hoc Dunn tests indicated significant differences in the range of motion for the different heights of the handling task. In order to decrease the load on the upper limbs during manual material handling activities, new box designs associated with worker training, need to be investigated in future studies.

In this work trying to understand how the education politics and of teachers' formation, in Brazil and in Portugal, they are attending to the present multiculturalidade in these countries. For this, I use the documentary inquiry for the gathering of the data and the analysis of content to describe and to understand these collected data. I carried out the collection of the data at two moments: the data of Portugal were collected in 2006, through a traineeship in the Faculty of Psychology and of Sciences of the Education of the University of Oporto and the data of Brazil were collected in the beginning of 2008. Besides the analysis of the documents also interviews were used semi-structured to understand the politics of teachers' formation and the actions implemented by the Brazilian and Portuguese Ministries of Education. In this form, I structured this work in three parts. In the first part I situates the theoretical referential system and methodology of the Theory, subdivided in four chapters. Firstly, I think about the context of the globalization and his impacts about the economy, about the politics, about the culture and, principally, about the education through the education politics. Next, I discuss the key concepts of the theoretical referential system and connect these concepts with the education of a general form. In the third chapter, I talk about the teachers' formation in front of the multicultural questions and the possible strategies to re-structure the formation of these professionals and, in the room chapter, I demonstrate the methodology used to develop the inquiry. In the second part of the work I present a characterization of the education and of the teachers' formation in Brazil and in Portugal. Already in the third and last part, I present the analysis of some legal Brazilian and Portuguese documents that indicate the necessity of an attention the multiculturalidade in the education of these countries and detach some advancements and retreats in this discussion.

This study is developed under the theoretical-methodological perspective of Semântica do Acontecimento, and its objective is to understand the function of argumentation and designation in the language, more specifically, analyze how juridical argumentation works. Our object of analysis was a lawsuit characterized as Indemnity Action3, through which the petitioners request the closure of a website where they were offended anonymously and the consequent indemnity payment. Firstly, we established two cenas enunciativas from the corpus characterized by the court cena and the website cena, composed of smaller cenas. Through this analysis, we could observe how argumentative orientation happens when mobilizing the speakers and the memoráveis present, as well as establish how the anonymity in this cena enunciativa works. For that, we established a relation between silence and rumor, studied by Orlandi4 (mmeo) and the anonymity present in court. It was possible, therefore, to conclude from the characterization of the cena the nonexistence of this anonymity. Secondly, we used the concept of Domínio Semantico de Determinação to observe how the designation of Court, space that moves the action, takes place. We observed a relation of antonymy in its designation, which characterizes it either as a space for offenses or as a space for indictment, and that, through the designations and the memoráveis, orient the argumentation to the advantage of the website closure, as well as indemnity payment to the petitioners.

Zn-Mn electrodeposition on to platinum using an acid electrolyte based on boric acid (BA) or boric-sorbitol complex (BSC) has been studied. The influence of these additives concentrations on the electrodeposition process was investigated by potentiodinâmic techniques, such as voltammetry, and the electrodeposits by SEM, EDS and XRD analyses. Voltammetric studies indicated that the feature characteristics Zn-Mn deposition voltammograms, without any additives or with BA or BSC both in different concentrations were similar, and that an increase in the BSC concentration led to decrease in the current density as for zinc deposition. The current efficiency of deposition process was lower 100 Porcentagem in the absence or presence of additives due to hydrogen evolution reaction and presence of compounds containing oxygen in the deposits. SEM analysis showed that Zn-Mn electrodeposits obtained at -1.60 V in the absence of additives or in the presence of 0.08 mol L-1 BA or 0.24 mol L-1 BSC were not dendritic. EDS analysis indicated that the Zn and Mn codeposition occurred beyond -1.50 V and also showed that for electrodeposits obtained at -1.60 V the increase of the BA or BSC concentration in the deposition bath induced to a decrease of the Mn content in the electrodeposit and that for BSC this decrease was more significant. X-Ray Diffraction analysis of the electrodeposits obtained in the absence or presence additives indicated that they were formed, in general, of a mixture of Zn, ZnMn2O4, ZnMnO3 and MnH0.8.

Interest and concern about mathematics teaching in early grades of elementary school were the driving force behind the making of this paper. The choice of investigative work as the main focus of the research reflects the search for leaving out mathematics teaching based on reproduction of procedures and algorithms. The work suggests a change in classroom dynamics by involving students in a more active way in their learning and mainly by motivating their creativity and reflection. The question which led the development of the research was: What are the limitations and the power of using investigative work in mathematics teaching in the early grades of elementary school starting from a teacher s actions and reflections? By aiming to help and expand the discussions over the usage of this kind of work, this qualitative study with action-research characteristics provides reflections on viability of the usage of this work in the early grades by polyvalent teachers. The theoretical references that support the research concern studies on investigative work and the changing scene suggested to the teacher when a new methodology is used. The references concerning this scene involve matters of fear and insecurity and point out reflection and partnership as a way of overcoming them. Data was obtained from a teacher and students from a third grade from a local public school and its collection was carried out through partnership between the teacher and the researcher at moments of study, preparation and reflection over the work done in the classroom. The data in this research was gathered through an interview with the teacher, audio and video recordings, questionnaire answered by the teacher and reports written by her, students records and researcher s notes. The analysis of the data was done in a way to highlight the moments that make up the classroom process in which it was possible to notice and highlight, through the teacher s actions and reflections, limitations and power of usage of investigative work in the early grades. The power identified in the investigation show the possibility of using this work in early grades mathematics teaching, thus contributing not only for the learning of mathematics, but also for the development of attitudes such as autonomy and mutual respect. The limitations observed in many moments were overcome or minimized by the teacher s reflexive attitude and group work, which was shared with the researcher. The study points out that if the disagreement between an innovative methodological proposal, such as mathematical investigation in early grades, and a school structure that privileges aspects of traditional teaching is not abandoned, even if the proposal proves itself successful, it will be limited to a small universe.

The present study aimed identify and analyze the conceptions expressed by Early Childhood Education professors on the inclusion process of children with special teaching needs in the Basic Education Level based on the Defectology Theory structured by Vigotsky (1997) and recognize, analyze and comment the subjective and objective working conditions that subsidize the thoughts and actions executed by professors during the inclusion process of children with special teaching needs in Early Childhood Education in the city of Sao Carlos. Thus, primary retrospective document researches and contemporary writings were conducted, along with the association of secondary data gathering and analysis. Documentary sources were public (official documents and parliamentary publication) and particular documents, associated with the qualitative and quantitative descriptive exploratory field research. Data gathering occurred with the recording and transcription of two interviews conducted with six Early Childhood Education professors from the city of Sao Carlos. All interviewers graduated in Pedagogy and present a teaching assignment position for more than five years. They were examined with three analysis guidelines established upon the goals determined for the present research: guideline 1 -subjective working conditions of the interviewed professors; guideline 2 objective working conditions of the interviewed professors; guideline 3 subjective and objective working conditions of the interviewed professors regarding the Inclusion-Exclusion of Children with Special Teaching Needs in Early Childhood in the city of Sao Carlos. The answers provided by the professors seemed to indicate a resistance to such process motivated by the lack of required information and knowledge regarding the professional performance, a personal feeling in synchrony with social meaning of the teaching profession manifested in the interviews, and an urgent need to review the salary policy of education professionals.

In this work, we investigated strategies to obtain polyurethanebased molecular composites containing metal oxide nanoparticles chemically attached to polyurethane polymeric chain. In Strategy 1, nanoparticles functionalized with OH organic groups were added in a typical reaction to obtain thermoplastic polyurethane. The obtained materials were transparent, presented brown-color and typical characteristics of thermoplastic polymers. The results revealed that the addition of functionalized nanoparticles plays an important role in the chain growth process, suggesting that nanoparticles OH organic groups are consumed during the polymerization process, forming a primary bond between the material components. However, it was not possible to identify that primary bond by the characterization methods used in this work. On the other hand, in the Strategy 2, efforts were spent on the development of methods to obtain functional organic molecules constituted by linear chains with silane groups in both ends (called here as connecting agents). The connecting agents were used as nanobuilding blocks in a condensation reaction with metal oxide nanoparticles in order to obtain a linear hybrid chain with alternated organic and inorganic blocks. Despite it was not possible obtain linear hybrid chain molecular composite, the results contributed to a better comprehension of the mechanism involved in that method, suggesting that the use small nanoparticles (< 10 nm) and large organic molecules (molar mass between 10.000 e 50.000 g/mol) is necessary to synthesize the linear hybrid chain. Furthermore, bifunctional nanoparticles must be used to avoid the formation of a tridimensional network by cross-linking processes.

In the attempt to find new electrolyte materials for Solid Oxide Fuel Cells (SOFC) that works at low temperature, perovskite-type materials have been intensively investigated. These materials have favorable crystal structure for the creation of oxygen vacancies since a variety of elements can be accommodate in the crystal lattice. Among these materials stands out LaAlO3-based perovskite which, when adequately doped, presents considerable ionic conductivity. However, in spite of doped LaAlO3 presents high ionic conductivity, it also presents p-type electronic conductivity under oxidizing conditions, which would limit his use as electrolyte. In this work, powders of pure LaAlO3 and Sr, Ca and Ba-doped individually and, in the case of Sr, also Pr and Mn-co-doped, were prepared by oxide mixture through successive calcinations. Samples, obtained via isostatic pressing, were sintered at 1500 and 1600 °C in air during 6 h of soaking time. Sintered samples were characterized by X-ray diffraction, scanning electron microscopy and impedance spectroscopy. Among the different kind of dopants (Ca, Ba and Sr), the Sr-doped sample was that one which had the higher conductivity, both the grain (σgrain = 1,8x10-2 S/cm at 800 °C) and total (σtotal = 9,3x10-3 S/cm at 800 °C) conductivity. Sr- and Pr-doped samples presented higher ionic conductivity than Pr-undoped samples (σtotal = 2,3x10-2 S/cm at 800 °C). This increase was attributed to the highest oxygen vacancy mobility since the presence of Pr+3 in crystal lattice did not introduce additional oxygen vacancies. The Mn co-doping generated samples with high electronic conductivity. It was also observed that all of the samples presented two common features: the total conductivity is controlled by the grain boundary, i. e., the grain boundary is more resistive than the grain, and the microstructures are two-phase and the majority phase is dopant depend.
