According to the studies in Applied Linguistics, this thesis is based on an interdisciplinary perspective (Critical Discourse Analysis, Sociology towards Social Change, Cultural Studies and Systemic-Functional Linguistics). The overall objective of the research was to analyze the discourses of Elementary School teachers in the state of Sergipe, by means of the discursive representations of the social actors, the processes of subjectivity and their fragmented identities in the context of standardized evaluations before the requirements of globalized pedagogical practices, based on the result-based management. The critical analysis of such discourses was motivated by the rapid pace with which the demands of innovation become part of the classroom, aiming at reaching the target in what concerns the indexes of the rankings which characterize the globalized discourse of the national education management, like Ideb (Basic Education Development Index), which makes teachers change their discourses, become silent or keep resistant. The work was initially endorsed by the theoretical lines of the Critical Discourse Analysis (FAIRCLOUGH, 2001, 2006), and poses a proposal for such purpose: the ASCD Discourse Sociological and Communicative Approach (PEDROSA, 2012, 2013). This is an interpretative-qualitative study of the Critical Discourse Analysis (FAIRCLOUGH, 2001, 2003; RAMALHO ; RESENDE, 2011) and to carry it out, semi-structured interviews were used as instruments of data generation (BAUER; GASKELL, 2011; GILL, 2011). Its corpus is composed of thirteen accounts of teachers from the Elementary school who teach Portuguese and work in the fifteen schools which were chosen to be the universe of the research at the Regional Board of Education (02) in the state of Sergipe. Such narratives are related to their impressions, expectations and actions which favor the management of results to which they have to submit themselves. The analytical overview of sociological and discursive line comes from the pan-semiotic categories (Inclusion and Exclusion) which appear in the theory of Representation of Social Actors (VAN LEEUWEN, 1997, 2008). To present the processes of subjectivity of these teachers, this work is based on the socio-analytical proposal of the classification of the subjects, which stems from the individual s work in the Gestão Relacional de Si , which comes from the Applied Sociology (towards) Social Change (BAJOIT, 2006, 2009). The discursive analyses were guided word for word, in their majority, by having the Systemic Functional Grammar as their theoretical basis, specifically by the processes of the Transitivity System postulated by Halliday, (1985); Halliday and Mathiessen, (2004); Eggins (2004); Cunha and Souza (2011). The work makes the field of Cultural Studies emerge towards the dialogue and the presentation of the fragmented identities of the teachers in the context of late modernity (GIDDENS, 2002; HALL, 2011). The thesis promoted a reflection over the teacher s condition, who is immerse in this context of knowledge construction of the present Brazilian educational system, the standardized evaluations, the indexes of development, the targets and the rankings. The considerations and outcomes of such a research dealt with the teachers emerging social practices and the need of planned initial and continuing teacher education towards the new moment which is foreseeable

The infographics historically experience the process of evolution of journalism, from the incipient models handmade in the eighteenth century to the inclusion of computers and sophisticated software today. In order to face the advent of TV against of the partiality readers of the printed newspaper, or to represent the Gulf War, where not allowed photography, infographics reaches modern levels of production and publication. The technical devices which enabled the infographics to evolve the environment of the internet, with conditions for the manipulation of the reader, incorporating video, audio and animations, so styling of interactive infographics. These digital models of information visualization recently arrived daily in the northeast and on their respective web sites with features regionalized. This paper therefore proposes to explore and describe the processes of producing the interactive infographics, taking the example of the Diário do Nordeste, Fortaleza, Ceará, whose department was created one year ago. Therefore, based on aspects that guide the theory of journalism, as newsmaking, filters that focus on productive routine (gatekeeping) and the construction stages of the news. This research also draws on the theoretical framework on the subject, in concepts essential characteristics of computer graphics, as well as the methodological procedures and systematic empirical observations in production routines of the newsroom who can testify limitations and / or advances

The following work is to interpret and analyze the problem of induction under a vision founded on set theory and probability theory as a basis for solution of its negative philosophical implications related to the systems of inductive logic in general. Due to the importance of the problem and the relatively recent developments in these fields of knowledge (early 20th century), as well as the visible relations between them and the process of inductive inference, it has been opened a field of relatively unexplored and promising possibilities. The key point of the study consists in modeling the information acquisition process using concepts of set theory, followed by a treatment using probability theory. Throughout the study it was identified as a major obstacle to the probabilistic justification, both: the problem of defining the concept of probability and that of rationality, as well as the subtle connection between the two. This finding called for a greater care in choosing the criterion of rationality to be considered in order to facilitate the treatment of the problem through such specific situations, but without losing their original characteristics so that the conclusions can be extended to classic cases such as the question about the continuity of the sunrise

In this thesis we study some problems related to petroleum reservoirs using methods and concepts of Statistical Physics. The thesis could be divided percolation problem in random multifractal support motivated by its potential application in modelling oil reservoirs. We develped an heterogeneous and anisotropic grid that followin two parts. The first one introduce a study of the percolations a random multifractal distribution of its sites. After, we determine the percolation threshold for this grid, the fractal dimension of the percolating cluster and the critical exponents ß and v. In the second part, we propose an alternative systematic of modelling and simulating oil reservoirs. We introduce a statistical model based in a stochastic formulation do Darcy Law. In this model, the distribution of permeabilities is localy equivalent to the basic model of bond percolation

In this work we investigate the stochastic behavior of a large class of systems with variable damping which are described by a time-dependent Lagrangian. Our stochastic approach is based on the Langevin treatment describing the motion of a classical Brownian particle of mass m. Two situations of physical interest are considered. In the first one, we discuss in detail an application of the standard Langevin treatment (white noise) for the variable damping system. In the second one, a more general viewpoint is adopted by assuming a given expression to the so-called collored noise. For both cases, the basic diffententiaql equations are analytically solved and al the quantities physically relevant are explicitly determined. The results depend on an arbitrary q parameter measuring how the behavior of the system departs from the standard brownian particle with constant viscosity. Several types of sthocastic behavior (superdiffusive and subdiffusive) are obteinded when the free pamameter varies continuosly. However, all the results of the conventional Langevin approach with constant damping are recovered in the limit q = 1

The standard kinetic theory for a nonrelativistic diluted gas is generalized in the spirit of the nonextensive statistic distribution introduced by Tsallis. The new formalism depends on an arbitrary q parameter measuring the degree of nonextensivity. In the limit q = 1, the extensive Maxwell-Boltzmann theory is recovered. Starting from a purely kinetic deduction of the velocity q-distribution function, the Boltzmann H-teorem is generalized for including the possibility of nonextensive out of equilibrium effects. Based on this investigation, it is proved that Tsallis' distribution is the necessary and sufficient condition defining a thermodynamic equilibrium state in the nonextensive context. This result follows naturally from the generalized transport equation and also from the extended H-theorem. Two physical applications of the nonextensive effects have been considered. Closed analytic expressions were obtained for the Doppler broadening of spectral lines from an excited gas, as well as, for the dispersion relations describing the eletrostatic oscillations in a diluted electronic plasma. In the later case, a comparison with the experimental results strongly suggests a Tsallis distribution with the q parameter smaller than unity. A complementary study is related to the thermodynamic behavior of a relativistic imperfect simple fluid. Using nonequilibrium thermodynamics, we show how the basic primary variables, namely: the energy momentum tensor, the particle and entropy fluxes depend on the several dissipative processes present in the fluid. The temperature variation law for this moving imperfect fluid is also obtained, and the Eckart and Landau-Lifshitz formulations are recovered as particular cases

Cet article a comme objectif présenter la contribution de la Psychologie Historique-Culturelle pour l'analyse critique de l'évaluation psychoéducationnel traditionnel et postuler les fondements pour la nouvelle modalité évaluative. Cette proposition se justifie à cause de l'actuelle révitalisation de l'usage des testes padronisés pour la mensuration des fonctions psychologiques, dues à la vulgarisation de la neuropsychologie. Historiquement les testes padronisés servent comme instrument pour attester cientifiquement l'idéologie de l'égalité entre les hommes dans la societé capitaliste que se maintient à travers de l'expropriation et de l'exclusion. En outre, il existe une forte tendence à attendre que les résultats expliquent l'intelligence comme inée ou considèrent les prédispositions héréditaires pour apprendre, ce qu'on oppose à la comprehénsion que les fonctions mentales sont formées dans le proccès de développement historique-social à travers l'appropriation de la culture humaine. Il est nécessaire donc une évaluation qui considère les médiations sociales (des instruments et des signes) comme constituants des fonctions psychologiques encourageant le développement de tous les individus et la non légitimation de l'exclusion sociale.

O presente artigo objetiva demonstrar o alcance das pedagogias do aprender a aprender (DUARTE, 2001), uma vez que elas fundamentam as propostas educacionais no âmbito nacional e no internacional, na atualidade; bem como apresentar suas principais premissas, que mantêm sua filiação ao pragmatismo e ao irracionalismo e, no limite, submetem o desenvolvimento humano à ordem do capital. Tais proposições se contrapõem ao objetivo humanizador da educação escolar pressuposto na produção teórica do psicólogo soviético Alexis Leontiev. Como resultados, temos que, dessas produções, é possível extrair subsídios para o enfrentamento do processo de esvaziamento do ensino escolar e do papel do professor engendrado pelas referidas pedagogias. Além disso, pretendese evidenciar a impossibilidade de aproximações entre as produções da psicologia histórico-cultural com outras correntes pedagógicas que estão a serviço da legitimação e do revigoramento da sociedade capitalista.

O presente artigo tem por objetivo abordar as bases, finalidades e composição de dois instrumentos de avaliação de juízo moral: a Moral Judgment Interview (MJI) e o Defining Issues Test (DIT), e um de competência moral: o Moral Judgment Test (MJT). Retoma a teoria do desenvolvimento moral de Kohlberg que fundamenta esses instrumentos, assim como os últimos estudos realizados com os mesmos. A MJI é uma entrevista semiestruturada que avalia o nível de juízo moral. O DIT é um teste objetivo que mede a proporção de respostas pós-convencionais. O MJT é um instrumento objetivo, que avalia a competência moral. Destaca-se a crescente utilização desses instrumentos em pesquisas sobre moralidade.

This thesis studied the motivation to work among health professionals of the Basic Unities (BUH) in the health network of the city of Natal (RN). It was understood that the work motivation is a process. Then, the expectation theory was applied and motivation components (results of work, expectative, valence, instrumentality, and motivational force) were used to analyses. It s understanding the motivation as multifaceted phenomenon, the psycho sociological perspective was adopted. The research was developed in two phases: one with application of Work Motivation and Meaning Inventory (WMMI), and another with interview. In the first phases, the analysis of results revealed that the major factors contributing to increase the motivational force to health professionals in the BUH´s are: in valence, Self Expression and Personal Realization (VF2), Personal and Family Survival (VF3); in expectative, Self Expression and Work Justice (EF1), Safety and Dignity (EF2) and Responsibility (EF4); in instrumentality, Involvement (IF1) and Recognition and Economic Independence (IF4). In opposition, the factors that more contribute to reduce the motivational force are Wear and Dehumanization factors in valence (VF4), in expectative (EF3), and in instrumentality (IF4), behind the Work Justice Factor (IF2). Basing in content analysis of interviews, it was possible to associate by equivalence, the senses presented by health professionals with obtained results of first phase, indicating that the results of second phase corroborated and complemented those of first one. This possibility broadened the comprehension of the studied phenomenon. In speaking of the respondents, it was visible the presence of contents showing that they perceive the Health System and BUH´s in degradation. In the first phase, the participants´ instruction also predict the results in motivation, and in the interviews can be saw that the instruction is associated with the opportunities in outside of system. As work motivation is a process, the impact of personal and occupational characteristics tend to interact with contextual aspects. It was concluded the majority of health professionals present the moderated motivational force, but it was falling because they experience and perceive a degrading context with work condition increasingly unfavorable.

The National Program for Youth Inclusion (ProJovem) has been created in 2005 in order to break the reproductive cycle of social inequality, through the improvement of the basic education and the professional qualification. Therefore, our objective is to discuss how the categories youth-work are inserted and implemented on ProJovem Integrado , which could be translated as Integrated , in Natal/RN. In 2008, ProJovem is has started to be executed based in four modalities: (1) Teenagers Socio-Educational Service, (2) Urban, (3) Worker and (4) Countryside Land Knowledge, aiming to serve a population from 15 to 29 years old who were seldom helped by specifics policies so far. In order to implement this research, three semi-structured interviews have been made, as well as observations at the program units and analysis of the official documents. In Natal, the operating modalities are: ProJovem Urban, which three units, divided in two districts of the city; the ProJovem Teenagers , which has ten units on Natal s four administrative regions; and ProJovem Worker , which were still structuring its courses until the beginning of the data collection. The data has been qualitatively analyzed through the Marxian Theory, tied to the Constant Comparative Method. The referred approach, based on the Grounded Theory, enables the understanding of the phenomenon s meanings through the perspective of the participants. The neighborhoods in which ProJovem s units are inserted has been characterized as well the Program s target. The results have been presented in three blocks: a) the modality s structure, which includes the implementation, functioning and operationalization of the activities; b) management of the modality s management, concerned to the main difficulties, expectations and functions; and c) the relation youth-work at the modalities. About the objectives and qualification and insertion goals, there is incongruence at the offer of occupational arches. We have observed that offered occupations are historically subservient and precarious. Hence they do not promote significant changes on the students career paths by usually inserting them into informal jobs or underemployments. Besides that, the professional qualification is very incipient. For that reason, it does not go with the necessary requirements to enable the youngster to enter the work world. It is considered that other researches are necessary to for better understanding of the remaining aspects of the relation youth-work

A partir dos diagnósticos das vulnerabilidades da condição juvenil contemporânea, as Políticas Públicas de Juventude tem ganhado maior força e um lugar mais definido nas pautas das demandas e conquistas sociais. Faz-se necessário, então, direcionar atenção para estas Políticas Públicas, a fim de promover uma reflexão sobre como ocorre a execução destas junto ao seu público alvo. Esta dissertação centraliza sua análise no Projovem Adolescente (PJA), uma das modalidades Programa Nacional de Inclusão de Jovens PROJOVEM que se destina ao atendimento de jovens com específica faixa etária entre 15 a 17 anos, com caráter assistencial e socioeducativo. Desta forma, o objetivo geral deste estudo foi discutir as ações do Projovem Adolescente no que diz respeito ao processo socioeducativo, a partir da perspectiva dos adolescentes participantes da cidade de Natal/RN. E, especificamente, objetivou-se: investigar de que maneira os adolescentes avaliam as atividades das quais participam, considerando se suas expectativas coincidem com as propostas do serviço; averiguar a participação dos adolescentes na elaboração, execução e avaliação das ações socioeducativas do serviço; bem como compreender as motivações que contribuem para a inserção e permanência ou evasão dos adolescentes no PJA. Para tanto foram realizados três grupos focais com adolescentes participantes do Projovem Adolescente, em diferentes núcleos do serviço, no município de Natal/RN. Cada grupo focal contou com dois encontros, em que primeiramente foram debatidos aspectos da participação nas ações socioeducativas e, num segundo encontro foram realizadas oficinas de produção de fanzines. A análise qualitativa dos dados foi realizada a partir da perspectiva teórica do materialismo histórico-dialético, utilizando-se como método de análise o Método Comparativo Constante, baseado na Teoria Fundamentada, que busca compreender o significado do fenômeno sob a perspectiva dos participantes. Os resultados foram apresentados divididos em eixos de análise os quais versaram sobre: as concepções dos jovens sobre adolescência e juventude; e a participação nas ações socioeducativas do PJA, destacando-se as características positivas e negativas apontadas pelos participantes, a relação dos jovens com o trabalho e as possibilidades e contribuições do PJA em seus contextos de vida. Em vista da análise empreendida, é possível constatar que a concepção dos participantes sobre a própria vivência da adolescência e juventude se encontra marcada pela absorção de determinadas imagens socialmente atribuídas aos jovens, como a que considera a juventude enquanto etapa de preparação para o mundo adulto. A participação nas ações socioeducativas, por sua vez, foi, de uma maneira geral, avaliada positivamente pelos participantes, não obstante esta avaliação, os jovens apresentaram uma visão muito crítica sobre a execução do serviço no município de Natal, relatando conhecer bem as dificuldades de ordem da gestão, bem como as contradições e limitações nas ações do serviço. Compreende-se a perspectiva da inclusão social no contexto neoliberal em que são implementadas as políticas sociais, contudo acredita-se que dar voz aos jovens participantes contribuiu para proporcionar uma reflexão sobre o modo como as políticas sociais, através do Projovem Adolescente tem atingido seu público, considerando as questões e perspectivas apresentadas pelos jovens como ferramentas a serviço das juventudes na construção de políticas democráticas e efetivas

This master s dissertation deals with motivation and the meaning of work amongst bank employees. This is done considering a cognitive perception. Work is understood here under a social and subjective comprehension, once it deals with significance attribution. Motivation is the process that rules choice of the different possibilities of individual behavior, all of which according to the Expectation Theory. This study aims to analyze the implications of the productive restructure, since it is related to technological innovation, organizational changes and management, in motivation and work significance. Thus, the objective of the research is to verify motivational differences and the meaning of work amongst bank employees. This is done in two distinct moments of the productive restructure of bank employees in Natal-RN. The research is divided in two parts. In the first one, changes that occurred in banks between 1999 until 2005 were identified by the means of interviews with 7 bank managers. The analyzed perspective was training intensifying, quality emphasis of customer attendance, the use of automation/technology, staff stabilization, change in staff profile, work intensification, etc. In the second study the Inventory of Motivation and Work Meaning was applied. Thus, questions related to work focus, social demographic data, in 187 bank employees were dealt with. The collected data was compared to data from previous work. It was observed that productive restructure has a reflection in the meaning of work increasing self-expression, economical reward, and responsibility in work conditions. All of the item mention beforehand maintain the level of inhumanness and consummation and respond as being the characteristics of the real work environment. On the other hand, bank employees value less justice, self-expression and more the survival perspective, implying instrumental values to work. As for motivation, it is increased among bank employees. These employees have greater expectations that their work produce results since they believe in their interference in work results
