This study it treats on the marks of the school experience in the individuation process of the subject and has as general aim to know of that it forms these experiences, the spite of the curricular and pedagogical questions, influences this process. It searched to interpret the experiences strengthened during the school education and the trajectories of confrontation of the diverse situations lived in the school. It was tried,also,to understand the direction of the critical school events and equally as the familiar way can influence in the choices and formation of the citizens through the pedagogical investment. Furthermore, it was reflected on the reasons that had taken some to remain in the school environment are as student or, later, of the side of there ,as teacher. For in such a way, it realized a qualitative research with a phenomenological inspiration using narratives interviews carried with four subjects, from which if it identified the main characteristics, structure, conditions of origin, the social context, the school strategies, the forms as they had been managed and its consequences. The analysis of the stories clearly left two basic axles about the school experience that if detach in the constitution of the subjects: in a hand, the dynamics of the lived school environment left undeleted marks in the memory that had been determinative for the personal choices; on the other hand,the familiar reference, through its different forms of pedagogical investment,had a decisive influence. The agreed marks of the school and the family had left an important legacy for formation of the subjects and the choices that had made during their lives, especially in the aiming of its professional careers. Invariably, it was perceived in the inquiry, that much of the pupil who if was persists in the adult and professional of today. Thus, the school I it s part of professional I that it exists in each one. The citizen, the person and the professional are derived from the processes of socialization and individuation, which to a large extent are defined during the school life. And it s with the use of this school capital , acquired in the school times, that we have conditions to develop the many social roles in the current days

The study theme is the Rural Familiar House Program (RFHP), through the Rural Familiar House of Uruará-PA city (URFH), from 2000 to 2005. It is considered as base the education offered to the field young people, in the modality of basic education by alternation methodology between the Familiar and School Times in the two first from 5th to 8th grade classrooms. From the argument about the understanding importance and need of knowledge transmission and construction to be established in the inter-section between general references of the social reality and the subjective ones. It constitutes an educative work that both values domain of knowing and the creative capacity of each pupil. Considering that the greatest aim of the education is the human being emancipation, this thematic for the development of the documentary and field research was defined with the delimitated thematic for the educative practice-proposal in alternation, choosing the Program of the RFHs as the reference to carry out an analysis which considered fruitful in the articulation between education and educative work. This study had the objective to contribute for the debate concerning the alternation and to understand presuposals and educative practice of the RFHs what its importance for the young people and its relation with the field educational policy. For this, it was used, mainly, from analytical references of authors, such as Williams, Gramsci, Adorno, Freire, Shiva, Soares, Molina, Tonet, et. all, all were also important for the construction of this work. The studied documentary sources, as well as the verbal ones the actors also interviewed had allowed, in irreplaceable way and significantly, a critical analysis on the pedagogical proposals and the articulation among school, familiar work and education, which was carried out in the formation of URFH, the sessions of alternation between Time School and Time Family. The results are scored with the chapter construction, as they had presented themselves in several sources and the reading which was made. A reading that signals for the affirmation which is possible to overtake the emphasis on technicality, mediated in the practice-theory-practice relation, still present in the alternation, and, thus, to be able to make an educative work that intends to contribute for the young people education with capacity of being, thinking and to act actually as subjects of their history

Most knowledge and techniques developed by mankind since ancient times had the main purpose to study and understand the various phenomena of Nature. Science, like one of these narratives, works as a translation, transcribing what, is systematically observed. Within the set of transformations on the modern sciences, the dialogue with related areas became quite narrow and, occasionally, functional, and the dialogue with non-related areas, in turn, does not takes place by any matters. The focus of this research is the teaching of Biological Sciences, and the undergraduate courses as strategic places to disseminate a broad understanding of Nature, that broadens the conceptual relations between different disciplinary axes, previously fragmented. In order to do so, I take a four-way metaphorical approach as a methodological construction base. Three of them proposed by Joël de Rosnay, represented by artifacts: The Telescope, The Microscope and the Macroscope. And finally, a proposition that complements the approach, that i named The Naked Eye. In Telescope, which allows a more general construct of a phenomenon, I discuss the teaching of Biological Sciences in Brazil. In the microscope, which allows us to analyze in detail a scenario, I construct a rank of the major courses in biological sciences and propose a discussion on the understanding of nature on the undergraduate programs. In Macroscope, who allows, at the same time, zoom in and out to the phenomenon observed, I call for a transdisciplinary dialogue, based on the authors Ilya Prigogine, Basarab Nicolescu, Henri Atlan and Bruno Latour, which can certainly contribute to the curriculum of the Biologists training programs, that builds knowledge pertinent to a complex observation of Nature. I complete the set of the quaternary reading and understanding of the world from the Naked Eye, as the first strategy of perception in our species. For this, I invite the philosopher of Nature Chico Lucas da Silva as my interlocutor

New multimedia applications that use the Internet as a communication media are pressing for the development of new technologies, such as: MPLS (Multiprotocol Label Switching) and DiffServ. These technologies introduce new and powerful features to the Internet backbone, as the provision of QoS (Quality of Service) capabilities. However, to obtain a true end-to-end QoS, it is not enough to implement such technologies in the network core, it becomes indispensable to extend such improvements to the access networks, what is the aim of the several works presently under development. To contribute to this process, this Thesis presents the RSVP-SVC (Resource Reservation Protocol Switched Virtual Connection) that consists in an extension of RSVP-TE. The RSVP-SVC is presented herein as a mean to support a true end-to-end QoS, through the extension of MPLS scope. Thus, it is specified a Switched Virtual Connection (SVC) service to be used in the context of a MPLS User-to-Network Interface (MPLS UNI), that is able to efficiently establish and activate Label Switched Paths (LSP), starting from the access routers that satisfy the QoS requirements demanded by the applications. The RSVP-SVC was specified in Estelle, a Formal Description Technique (FDT) standardized by ISO. The edition, compilation, verification and simulation of RSVP-SVC were made by the EDT (Estelle Development Toolset) software. The benefits and most important issues to be considered when using the proposed protocol are also included

Geopolymers are cementing materials that depict a number of advantages compared to Portland cement. Contrary to the latter, geopolymers are synthesized at room temperature, thus significantly reducing the emission of CO2 to the atmosphere. Moreover, the composition and synthesis reactions can be tailored to adjust the setting time of the material as well as its compressive mechanical strength. It is then possible to produce geopolymeric cements with short setting times and high compressive strength, although relatively brittle. The objective of the present study was to produce and characterize composite materials by reinforcing fastsetting geopolymeric matrixes with polypropylene geosynthetics (geomats and geotextiles) in an attempt to improve the toughness and tensile strength of the cementing material. Geosynthetics have been increasingly used to reinforce engineering structures, providing higher strength and better toughness. In particular, polypropylene nonwoven and geomats depict other attractive properties such as low density, durability, impact absorption and resistance to abrasion. Fast-setting geopolymers were then synthesized and reinforced with polypropylene nonwoven and geomats. The mechanical strength of the materials, reinforced or not, was characterized. The results showed that relatively short setting times and adequate flowing behavior were achieved by adjusting the composition of the geopolymer. In addition, it is possible to improve the fracture resistance of geopolymeric cements by adding polypropylene geosynthetics. The best results were achieved by reinforcing geopolymer with polypropylene TNT

João Cabral de Melo Neto n a jamais aimé les vers sentimentaux et prolixes venus de la tradition romantique. C est pour ça que son uvre a un discours objectif, rigoureusement elaboré e elle comporte certaines influences concretistes ça explique pourquoi l auteur est connu comme l ingénieur de la langage. En verité, le poète même dissait qu il était un homme froid et rationnel. La critique a assidument analysé la matière logique et le rigeuer formel de l uvre de Cabral de Melo. Pourtant, dans ce travail nous analysons les poèmes dont le sentiments humaines sont la mtière principal de l élaboration de l experiènce esthétique. La poèsie de João Cabral n est pas simple verbalisme formel, ni un uvre sens vie, car les objects concrètes et la langage objectif n empêchent pas qui le sujet décrit avec émotion les scènes presents dans les poèmes. Nous travaillons avec la hypothèse de que le poète a une attitude trop humaine quand il parle de l experience culturel et de l experience de la vie dans le Nord-est brésilien. Les unités témathiques de ce travail, pourtant, montrent la représentation du Nord-est dans la poèsie de João Cabral et examinent aussi le sentiment qu il sent par la memoire culturel de sa région. Parmi les aspects qui composent sa lyrique humaine nous citons la personification constant de les paysages du Nord-est le poète ne veux pas faire une décrition tophographique de la région parce que les places ont un valeuer sentimentel pour lui; au moyen d un discours erotique, Cabral represente les desirs et les intints humaines de sa terre; ensuite, il semble que le poète est enchanté et enveloppé avec certains elemets culturels de sa région, come l hamac, la littérature oral et la musique régional; la preoccupation avec la population explorée et la denonciation de la condition miserable dans le Nord-est brésilien confirment aussi la humanité présent dans son uvre; finalment, la récordation de l enfance et la nostalgie du temps passé sont, pour le poète, un possibilité qui peut aider dans la formation humaine de la population

This work analyzes the behavior of the adversative connectors in the speech of the user of Natal, with views to suggest implications for the grammar teaching in the high school Portuguese languages classes. It is an investigation that sits on the functionalist paradigm, specifically in the protected ideas for Givón. For so much, data of situations of speech from the corpus Discurso e gramática lingual falada e escrita da cidade do Natal (FURTADO DA CUNHA, 1998). The sample embraces a total of forty interviews, of which the occurrences are cut out whose registrations mark the existence of adversatives constructions in narratives of personal experience and in the opinion reports, modality of oral language, of the mentioned database. The work revisits authors of the grammar, Cunha (1986); Bechara (2006); Perini (2006), among others; authors that contemplate referring approaches to the use of opposition connectors as: Barreto (1999); Tavares (2003); Longhin (2003); Silva (2005); Rocha (2006); Neves (2000, 2006). The results of the panoramic analysis reveal as adversity connectors in use for the habitant of Natal, for recurrence order, the mas, e, aí, agora, só que, no entanto and já. Analyzed the results, the same ones are compared with the treatment presented by the traditional grammar, with application of functional iconicity principle, markdness principle and the prototype of the category is chosen. In the differentiated analysis of the item " agora ", structural profile of the constructions is analyzed that involve the item, semantic profile, times, manners and aspects of the verbs that they wrap up in the constructions in reference, trajectory of grammaticalization and comparison with the prototype of the category. Finally, they are suggested implications of whole the study for the teaching of Portuguese language, in the high school classes

Existem vários métodos de simulação para calcular as propriedades críticas de sistemas; neste trabalho utilizamos a dinâmica de tempos curtos, com o intuito de testar a eficiência desta técnica aplicando-a ao modelo de Ising com diluição de sítios. A Dinâmica de tempos curtos em combinação com o método de Monte Carlos verificou que mesmo longe do equilíbrio termodinâmico o sistema já se mostra insensível aos detalhes microscópicos das interações locais e portanto, o seu comportamento universal pode ser estudado ainda no regime de não-equilíbrio, evitando-se o problema do alentecimento crítico ( critical slowing down ) a que sistema em equilíbrio fica submetido quando está na temperatura crítica. O trabalho de Huse e Janssen mostrou um comportamento universal e uma lei de escala nos sistemas críticos fora do equilíbrio e identificou a existência de um novo expoente crítico dinâmico θ, associado ao comportamento anômalo da magnetização. Fazemos uima breve revisão das transições de fase e fenômeno críticos. Descrevemos o modelo de Ising, a técnica de Monte Carlo e por final, a dinâmica de tempos curtos. Aplicamos a dinâmica de tempos curtos para o modelo de Insing ferromagnéticos em uma rede quadrada com diluição de sítios. Calculamos o expoente dinâmicos θ e z, onde verificamos que existe quebra de classe de universilidade com relação às diferentes concentrações de sítios (p=0.70,0.75,0.80,0.85,0.90,0.95,1.00). calculamos também os expoentes estáticos β e v, onde encontramos pequenas variações com a desordem. Finalmente, apresentamos nossas conclusões e possíveis extensões deste trabalho

Dans ce texte, nous prenons avec probleme le départment bresilien de Piauí comme espacialité de la Région « Nordeste », suivant les instants de son insertion politique et discursif dans l'identité régionale, qui s'est donnée entre la fin des années 1950 et débuts des années 1970. Pour ceci, nous proposons une analyse de discours identitaires de Piauí comme la littérature et le folklore produits alors, cherchant à rapporter telles discours avec les pratiques et intérêts politiques qui ont concouru pour la « nordestinization » de Piauí. Parmi ces discours et dans dialogue avec eux, nous prenons centralement l'oeuvre du juge et ecrivain João Nonon de Moura Fontes Ibiapina, emisseur de signes qui apparaît en ce moment. Notre objectif est discuter les images élaborées sur Piauí et son inclusion dans les stéréotypes cristallisés de Nordeste, comme la pauvreté et la nécessité, la vie dans le champs et la prédominance d'une « culture populaire » régionale. Dans une période d'importantes mutations dans la société brésilienne, dans la production culturelle, dans heurtes régionalistes Nordeste et dans les formes de penser et pratiquer les espaces, les intellectuels de Piauí que nous étudions ont essayé de recouvrir de mots et de sens la noirceur et l'incommode silence concernant le Piauí dans la Nation bresilienne, quand le déparment s'intégrait, au moyen de la Région, au Brésil urbain et industrialisé

This study aims to analyze the process of resignification of Chile Street, in Natal, from the development of a music scene in the late 1990s. Chile Street, as part of the Historic Centre of Natal, had its images constructed from the discursive practices and everyday life of its regular visitors, leading to a series of symbolic and imaging transformations throughout the twentieth century. Initially transformed into glamorous space as a result of urban actions of the new republic of Albuquerque Maranhão, in the early twentieth century, Ribeira and Chile Street, specifically, came to be seen as bohemian area, during the war time"; followed by a marginal phase, it was eventually transformed into the main rocker area of Natal, with the development of a musical scene in the second half of the 1990s. This music scene, its practices, economic interests, cultural events and identity ties created among their practitioners made Chile Street, "in the time of Blackout night club", an "alternative" space. As the historic centers, inserted in the logic of postmodern city marketing, both spaces are dynamic in their practices, as in their images, Chile Street also suffered changes in its meanings and symbols, around the year 2000 when the alternative-underground space became a pop space, where people from various parts of the city began attending its events and places, transforming it into a point of very heterogeneous sociability

The pro-ecological commitment (CPE) constitutes an important topic within Person- Environment Studies, here seen as a predisposition to practices that result in environmental protection. Under the framework of sustainability, the concept of sustainable behavior emerges, covering, in addition to CPE, new psychological dimensions such as: the future time perspective (PTF) and the ecological worldviews (VEM). The current study intended to explore the concept of sustainable behavior of university students, by means of the association among some of its dimensions: CPE, PTF and VEM. For this purpose, 380 undergraduate students of biology, ecology, nursing, geography, and social service answered a form containing: socio-demographic questionnaire, a question on self-assessment of environmental care, the Scale of Ecocentric and Anthropocentric Environmentalisms, the Scale Consideration of Future Consequences, and the Scale Ecological Worldviews. Based on descriptive and correlational procedures, it was found that 78% of the participants practice or have practiced environmental care (caregivers) and the spread of information has been the practice more frequently reported, and the source of influence for such practices were the school, social networks, and the contact with nature It was also observed the association between practice of environmental care and ecocentric environmentalism, consideration of future consequences and egalitarian worldview (worldview of fragile nature). The lack of environmental care was associated with anthropocentric environmentalism, apathy, and individualistic worldview (worldview of passivity). As expected, and suggested by the literature, positive association were found between the sustainable behavior dimensions investigated in this study and the practice of environmental care

The thesis presented here is of interest management to analyze the performance of the State, through the materialization of the professional courses, the process of integration of users CRAS-Pajuçara informal. Therefore, we assume that poverty and inequality reach a significant portion of the world population, in a context where the working class family is seen as an alternative to face the multiple expressions of social issues. Thus, before the changes of Productive Restructuring, marked by flexibility, outsourcing and casualization of labor relations in the world, the working class family must find ways to ensure their survival. In this direction, we discuss the advances, limitations and challenges posed to the Social Assistance Policy in contemporary, situating this context, the role of the state. Furthermore, we discussed the functionality of informality to the capitalist system, showing how capital appropriates of informal work, placing it in its logic, and thus makes the capital-labor ratio increasingly predatory, inhuman and unequal. The methodological procedures for the preparation of this study constitute a literature and documentary, beyond 10 semi-structured interviews directed to users of CRAS-Pajuçara, participants of training courses for the period 2010-2011. In light of the critical-dialectical rationality, and in a context where informal work has increasingly been co-opted as an alternative to huge unemployment in the same direction in which the welfare rises in tackling social inequality, the scope of this study, discusses and reveals the truths and misconceptions that surround this bourgeois discourse, in times of crisis of capital, the city of Natal, Brazil

This master thesis aimed to investigate how the power relations operating in the tourism social processes, have shaped the urbanization of Ponta Negra district, Natal, Rio Grande do Norte - RN. The study assumes that the production of space is the result of global phenomena individualized by local forces a process of glocalization. The method used was the case study. It used primary and secondary data and information were treated using the technique of content analysis. The urbanization of Ponta Negra is inserted in the context of global process triggered in the 1970s. The Park of Dunas and Costeira Highway (PD/VC) urbanization project marks the beginning of the Tourisms since 1979. The period in focus was 1979 to 2009. The tourism was dived into four major sections time: tourism in Natal before the Coastal Highway (1939-1979); Project Parque das Dunas / Coastal Highway to the first boom in domestic tourism (1979 - 1990); the internationalization of tourism (1991-2000) and, of first "boom" to "decline" of international tourism (2001-2009). Based on the historical evolution of the tourism were elected three different social processes, able to demonstrate how relations of social forces brought in space act on them and help shape the process of urbanization of the neighborhood in question: The removal of beach hut , the soccer field Botafogo Football Club and the skyscrapers . Finally, it should summarize the research identified interests and conflicts among the actors that form the thrust of spatial transformations: cultural conflicts resulting from the imposition of social practices that differ from the taste of native; clashes between different groups that reflect the duality between use value and exchange value; and interests in land values. In addition, demonstrated that the social relations that involve the production of the area are stimulated by deep-seated societal processes historically and camouflaged by market relations and a modern facade that the city has acquired in recent times; revealed that the actors are linked in networks to increase their influence and that this influence varies mainly according to economic and political power that they or their associates hold

Este trabalho tem por objetivo discutir os nexos entre crise do capital, questão urbana e ambiental, problematizando a inserção subordinada do Brasil no processo de mundialização com predomínio das finanças, as contradições que marcam estes processos e, em particular, suas repercussões nas cidades na contemporaneidade. Acirra-se a luta de classes, expressa nas diversas formas formas de apropriação e uso do solo urbano. Neste cenário de disputas, as formas de luta e oposição à acumulação desenfreada do capital podem ser consideradas ainda pontuais e de pequena escala, mas revelam formas de resistências que podem vir a gerar movimentos emancipatórios
