O plano de texto e as marcas linguísticas da responsabilidade enunciativa no artigo de opinião do vestibular 2010 da UFRN

With this thesis, we investigate papers produced by candidates to the vestibular 2010 from UFRN related to the (non) taking on of different points of view in the textual zone of the argumentation and counter-argumentation. The candidates had to produce an opinion article about the polemic theme of the security cameras. The corpus of this research contents 100 papers produced by the candidates to the vestibular 2010 from different areas (humans I, humans II, technological I, technological II and biomedical). To this study, we are based on theoretical perspectives from authors of different theories and linguistic fields that dialog among them. In this direction, we follow Bakhtin (1995), Rabatel (2008 a, 2008 b), Guentchéva (1994, 1996, 2011) and Rodrigues, Passeggi e Silva Neto (2010), among others, that are concerned to dialogism, enunciative theories, discuss analyzes, and linguistic of the text. This group of linguistic approach is linked to the Textual Analyze of the Discuss (ADAM, 2011), that conducts analyze of the data of this research. Related to the methodology, we follow the qualitative analyze in an interpretative way. We investigate how the candidate, as a writer, takes on information inserted in his/her paper. With this in mind, this research tries to answer the following questions: (1) How the candidate organizes his/her discuss in respect to the enunciative responsibility? (2) Which linguistic marks conduct to identify the different voices in the texts? (3) How the textual plan is presented in the opinion article? (4) In which part of the textual plan is possible to identify the enunciative responsibility? In this sense, the aims of this study are identify, describe, analyze and interpret the different voices presented in the text and the way the candidate takes on (or not) the different points of view presented in the papers during argumentation and counterargumentation movement. In general, the results reveal that the presence of linguistic marks (connectors, people marks, among others) design the grade of enunciative responsibility of the writer, stimulating his/her involving and taking on enunciative responsibility.

Ensino de teatro e diálogo freireano: uma experiência junto ao PIBID-Teatro/UFRN

This work aims, from the exchange and dialogue with the agents involved in the research process, discuss the ways for planning a Dialogic Teaching Theatre proposed by the Institutional Scholarship Program Introduction to Teaching subproject Theatre UFRN, considering Freire's thought in relation to the dialogue, and the teaching moments (Study of Reality, Knowledge Organization and Application of Knowledge) proposed by the Group of Studies and educational Practices in Movement UFRN. The research develops a joint effort with stakeholders relying on the "dialogical" and "problem-based approach" as mobilizing methodological foundations for the construction of knowledge in both the group PIBID Theatre / UFRN, as the group attended by fellows of this program in Municipal school Professor Laércio Fernandes Monteiro, on Natal-RN. Through a participatory research, a constant movement of action-reflection-action, and making use of some instruments of school ethnography, as participant observation, unstructured interviews, and graphics and textual records, is that it has trodden and built the search this way, experiencing and questioning the experience. Thus, the theoretical framework of this thesis are located on Paulo Freire's work as it relates primarily to the dialogical education, in pedagogical systematization of the Study Group and Educational Practices in Movement (GEPEM / UFRN), and the Research Laboratory of production scenography and scene Technologies (CENOTEC / UFRN), with regard to the construction of an educational process that considers the realities of the subjects in connecting these realities and specific knowledge of the taught area, relationships between specific area and other areas of knowledge, and recognizing the school as a space for dialogue.

Corpos da Ciranda: narrativas poéticas, artístico/estética da ciranda de Lia de Itamaracá

This research is a study that deals with the language of the players bodies of Ciranda (a typical dance in circle in Brazil) – more specifically the one of Lia from Itamaracá. Our interest is to observe how this body dances, communicates, writes on time and space, establishing relations that complement and help to remain in construction. Thus, in a circular way and in an energy that is transmitted with the contact of the touch of the hands, in the power of song, in a circle that can be seen from many places, but by different angles, holding on that the particularities of its subjects players/dancers/observers, and that we propose ourselves to think: who are those players bodies and how do they build the circles of Ciranda? Therefore, during the pathway of the research, we were conducted by the phenomenological method and, from this, used the concepts of lived and sensible world. Our interest in this manifestation is, also, the body that dances and insert itself in the artistic expression, meaning and opening itself to the knowledge by the experience. Therefore, we assume a conception of the body that refers itself in the merleaupontyana fenomenologic approach, in this way, in its criativity in relation to the body as a fragmented being, as it is pointed by the Cartesiana theory. In this perspective, we understand the body in its relations with the culturals, sociais, economics and artistics issues that integrates it, in others words, in the relations that helped us to better understand the body as it is. This way, this research has as main objective to present the refletions about the players body, mainly, of Lia from Itamaracá and with this body to dance, to communicate, to write itself on time and space, estabilishing relations that complement and help to stay in construction. Such a statement leads us in this work, to inquire, for example: what mobilizes those subjects on this dance? We understand that elements as the place that is always in modification, the costumes, the musicality and the change in the movimentation of the players body in each new circle, those elements are factors that activate a permanente reconfiguration that are happening in the Ciranda dance nowadays. Finally, we assert that this investigation comes in reason to the big dimension that the Ciranda has achivied in Brazil, especially in the Northeast, as the existence of few references and registers of the reseach manifestation in the academic areas. It is possible to verify, in this research, that, in reason to this spreading, the nuances of the players bodies is even more diversified and that the missing of experiences on Itamaracá island - PE, its origin has putting away the original and community, becames, more and more, a dance of others stages and squares.

Conception, synthèse et activité anticancéreuse d’analogues basés sur la molécule FTY720 (Gilenya)

FTY720 (aussi connu sous le nom de Fingolimod ou Gilenya) agit sur les récepteurs sphingosine-1-phosphate (S1P) et induit la suppression du système immunitaire (immunosuppression). Cette molécule est reconnue pour avoir une activité contre plusieurs cellules cancéreuses. Cette activité est indépendante de l’action sur les récepteurs S1P et on attribue plutôt la mort (apoptose) des cellules cancéreuse à la capacité que possède la molécule à réduire le transport des nutriments dans la cellule. Toutefois, malgré ses nombreux avantages, FTY720 ne peut pas être utilisé afin de traiter des humains puisque l’activation secondaire des récepteurs S1P1 et S1P3 mènent à une diminution du rythme cardiaque (bradycardie) chez les patients. Notre groupe s’est donc concentré sur la synthèse d’analogues qui potentiellement n’activeraient pas le récepteur S1P tout en gardant une activité biologique contre plusieurs cellules cancéreuses. Malgré le fait que nos analogues agissent également sur la diminution du transport des nutriments dans les cellules, nous ne connaissons pas le mécanisme d’action par lequel ceux-ci agissent. Au passage, le projet de recherche ci-présenté nous aura par ailleurs permis de développer une grande variété de sondes photo-actives dans l’espoir d’isoler une ou plusieurs protéines qui seraient impliquées dans le mécanisme d’action.

‘Do you want to see my hornpipe?’: the traditional Irish dancing body at play in the work of Jean Butler and Colin Dunne’, in Anthony Shay and Barbara Sellers-Young (eds.), The Oxford Handbook of Dance and Ethnicity, Oxford: Oxford University Press, 2016, pp.41-65.

This chapter considers the radical reimaginings of traditional Irish step dance in the recent works of Jean Butler and Colin Dunne, in which the Irish step-dancing body is separated from its historical roots in nationalism, from the exhibitionism required by the competitive form, and from the spectacularization of the commercialized theatrical format. In these works the traditional form undergoes a critical interrogation in which the dancers attempt to depart from the determinacy of the traditional technique, while acknowledging its formation of their corporealities; the Irish step-dance technique becomes a springboard for creative experimentation. To consider the importance of the creative potential revealed by these works, this chapter contextualizes them within the dance background from which they emerged, outlining the history of competitive step dancing in Ireland, the “modernization” of traditional Irish dance with the emergence of Riverdance (1994), and the experiments of Ireland’s national folk theater, Siamsa Tíre.

Conception, développement et validation expérimentale d’une boussole haptique

Ce mémoire présente la conception, le contrôle et la validation expérimentale d’une boussole haptique servant à diriger les utilisateurs aux prises avec une déficience visuelle, et ce, dans tous les environnements. La revue de littérature décrit le besoin pour un guidage haptique et permet de mettre en perspective cette technologie dans le marché actuel. La boussole proposée utilise le principe de couples asymétriques. Son design est basé sur une architecture de moteur à entraînement direct et un contrôle en boucle ouverte étalonné au préalable. Cette conception permet d’atteindre une vaste plage de fréquences pour la rétroaction haptique. Les propriétés mécaniques de l’assemblage sont évaluées. Puis, l’étalonnage des couples permet d’assurer que le contrôle en boucle ouverte produit des couples avec une précision suffisante. Un premier test avec des utilisateurs a permis d’identifier que les paramètres de fréquence entre 5 et 15 Hz combinés avec des couples au-delà de 40 mNm permettent d’atteindre une efficacité intéressante pour la tâche. L’expérience suivante démontre qu’utiliser une rétroaction haptique proportionnelle à l’erreur d’orientation améliore significativement les performances. Le concept est ensuite éprouvé avec dix-neuf sujets qui doivent se diriger sur un parcours avec l’aide seule de cette boussole haptique. Les résultats montrent que tous les sujets ont réussi à rencontrer tous les objectifs de la route, tout en maintenant des déviations latérales relativement faibles (0:39 m en moyenne). Les performances obtenues et les impressions des utilisateurs sont prometteuses et plaident en faveur de ce dispositif. Pour terminer, un modèle simplifié du comportement d’un individu pour la tâche d’orientation est développé et démontre l’importance de la personnalisation de l’appareil. Ce modèle est ensuite utilisé pour mettre en valeur la stratégie d’horizon défilant pour le placement de la cible intermédiaire actuelle dans un parcours sur une longue distance.

Controle social do espaço público: uma análise do conselho turístico pólo costa das dunas

The managing Conselho of public politics constitute one of the main experiences of democracy in Brazil contemporary representing a conquest for construction of a democratic institutionalism. The historical newness consists of the intensification and the institutionalization of the dialogue between government and society - in public and plural canals - as condition for an allocation more efficient joust and of the public resources. In this context the present study it objectified to understand from readings of the performance of represented group of bencheses the dynamics of functioning of the Tourist Conselho Pólo Costa das Dunas while space of participation and social control. The bibliographical research contemplated diverse sources in order to compile knowledge of credential authors in the quarrel of inherent subjects to the civil society and the public sphere to the construction of the citizenship to the conception formation and dynamics of the social control through Conselho of public politics. A qualitative perspective the case study was adopted as research method and for attainment of the data interviews with the members of the Conselho had been carried through beyond consultation the referring documents the dynamics of functioning of the Conselho. The profiles capacities and limitations of the members of the Conselho had been identified constitution social and dynamic organization of functioning of the Conselho and the readings of the members of the Conselho concerning the power to decide instances and participation. The results had shown that the allotment of being able in the Conselho does not occur of equal form. The functions of coordination of the activities of the Conselho are assumed by the representatives of the public agencies. Level of qualification of council members also if presents as difficulty to development of activities of Conselho since the majority of the interviewed ones disclosed unreliability and unfamiliarity when thematic specific that runs away from its organizacional reality they are boarded in the assemblies. Of this form the Conselho if presents more as half of institutional legitimation of what half of characterization of the creation of a public sphere properly said. Finally he could himself be concluded that a democratic culture inexists that inside crosses practical the institutional ones of the Conselho thus limiting the possibility to reach the effective social control of the public politics of tourism in the Rio Grande do Norte

O idoso e as ações sociais em prol desse grupo etário: um estudo sobre a qualidade de vida na Terceira Idade e o Projeto Saúde e Cidadania na Melhor Idade

The present study regards an applied qualitative social research (descriptive) which approaches the matter between old age and Brazilian social actions performed in social projects, aiming a qualified life and citizenship for this group of age. The objective of the study is to evaluate the contribution of Project Health and Citizenship in Old Age regarding social actions from the government directed to old age individual treatment for life quality improvement. The theoretical fundamentals of this work is, in a first moment, about old age and certain existing theories about aging process, as well as the differences and perspectives that come up throughout this process. In a second moment, some reflections are developed about the relation between life quality and leisure regarding old age, with the conception and historical rescue about these questions, as well as the evidence of leisure as an instrument of well-being feasibility and a better life quality in old age. Then the study contextualizes Brazilian government treatment to old age individuals, cutting off the Constitution of Republic from 1988 and some social attitudes taken by the government in a try to reach this specific group. Finally, the study presents the Project Health and Citizenship in Old Age , as a social program which belongs to extension activities from Federal Center of Technological Education of Rio Grande do Norte (CEFET-RN), which aims old age treatment and their citizenship and life quality. After the application of a semi-structured interview using the technique of Analysis of content for the Analysis and Discussion of Results, it is possible to conclude that the Project Health and Citizenship in Old Age fulfils its objective regarding contribution, through offered leisure activities, for old age well-being and life quality improvement. Hence, on this regard, it is possible to observe the importance and value of government actions, social projects and programs assisting old age individuals, for they are able to provide this group the opportunity to live out activities that allow their citizenship and socialization, regarding well-being and life quality improvement.

Conception, caractérisation et optimisation de SPAD en technologie Dalsa HV CMOS 0.8 μm pour intégration dans un 3D-SiPM

Résumé : Les photodiodes à avalanche monophotonique (SPAD) sont d'intérêts pour les applications requérant la détection de photons uniques avec une grande résolution temporelle, comme en physique des hautes énergies et en imagerie médicale. En fait, les matrices de SPAD, souvent appelés photomultiplicateurs sur silicium (SiPM), remplacent graduellement les tubes photomultiplicateurs (PMT) et les photodiodes à avalanche (APD). De plus, il y a une tendance à utiliser les matrices de SPAD en technologie CMOS afin d'obtenir des pixels intelligents optimisés pour la résolution temporelle. La fabrication de SPAD en technologie CMOS commerciale apporte plusieurs avantages par rapport aux procédés optoélectroniques comme le faible coût, la capacité de production, l'intégration d'électronique et la miniaturisation des systèmes. Cependant, le défaut principal du CMOS est le manque de flexibilité de conception au niveau de l'architecture du SPAD, causé par le caractère fixe et standardisé des étapes de fabrication en technologie CMOS. Un autre inconvénient des matrices de SPAD CMOS est la perte de surface photosensible amenée par la présence de circuits CMOS. Ce document présente la conception, la caractérisation et l'optimisation de SPAD fabriqués dans une technologie CMOS commerciale (Teledyne DALSA 0.8µm HV CMOS - TDSI CMOSP8G). Des modifications de procédé sur mesure ont été introduites en collaboration avec l'entreprise CMOS pour optimiser les SPAD tout en gardant la compatibilité CMOS. Les matrices de SPAD produites sont dédiées à être intégrées en 3D avec de l'électronique CMOS économique (TDSI) ou avec de l'électronique CMOS submicronique avancée, produisant ainsi un SiPM 3D numérique. Ce SiPM 3D innovateur vise à remplacer les PMT, les APD et les SiPM commerciaux dans les applications à haute résolution temporelle. L'objectif principal du groupe de recherche est de développer un SiPM 3D avec une résolution temporelle de 10 ps pour usage en physique des hautes énergies et en imagerie médicale. Ces applications demandent des procédés fiables avec une capacité de production certifiée, ce qui justifie la volonté de produire le SiPM 3D avec des technologies CMOS commerciales. Ce mémoire étudie la conception, la caractérisation et l'optimisation de SPAD fabriqués en technologie TDSI-CMOSP8G.

Identidade, memória e narrativas na dança de São Gonçalo do povoado Mussuca (SE)

This study deals with the participation of the dance of São Gonçalo of the Mussuca town/SE, in the process of construction of the ethnic identity among this social group. The Mussuca is a grouping recognized as afro-descendents, linked with black enslaved people in the valley of the Cotinguiba region. The collective memory functions as a drive of this linking with the past and if it makes to elaborate narratives on this descent. The objective of this study was to investigate the ways the rite went through to constitute itself as an element of ethnic representation. Internal and external agents had been identified who had participated in different contexts. By means of an ethnographic work we ve reached some aspects of the local structure social which demonstrated the contradictions through the social relations of the group. This process of ethnic autorecognition presents the kinship and the space question as definers of the social arrangements which establish its ethnic boundaries

O zambê é nossa cultura: o coco de zambê e a emergência étnica em Sibaúma, Tibau do Sul-RN

The coco de zambê is a dance of which origin is credited to old slaves who inhabited the coastalregion of Rio Grande do Norte. The zambê appears intensely in the narratives related to the past and present of Sibaúma, a quilombola community located in the southern coast of the state. It is conceived as a sign of ethnicity linked to a local black ancestry. The group is known as "remnant of Quilombo," and is demanding the process of territorial settlement, as guaranteed through the Brazilian federal constitution. The coco de zambê, presented as a kind of "certificate of ancestry to the group, besides, after a long period of abandonment, the dance is beeing "revitalized" and exploited by a part of the group alongside the demands for recognition. In this process there are several interlinked actors: NGOs, state agencies to promote the culture, representatives of public authorities and local leaders. Here, I'm interested in understanding how this process of revival occurs with the coco de zambê in Sibaúma: how a "brincadeira" (play) of the ancients comes to be a "cultural reference" and a means of political mobilization concerning their recognition

A cultura de índio, seu menino, vem de longe aqui : formação histórica e territorialização dos Tremembé/CE

This dissertation is based on the ethnography of a strategic selection of three Tremembé ethnic situations, which are situated in the backlands of Acaraú and Itarema, municipalities located in Ceará State (Northeast Brazil). My main aims are the following. Firstly, I reconstitute the historical and social formation of three localities, called Lagoa dos Negros, Telhas, and Queimadas, related to a particular origin myth which refers to Almofala, an extinct colonial Aldeamento in the seashore, where the Tremembé indians and other native populations were converted and gathered under missionary administration. According to the origin myth, these three localities were set up after a strong drought which happened in 1888 (the so called three eights) when a group of Tremembé families moved to the countryside and established close to the Lagoa dos Negros and, later on, they were segmented into smaller groups which started to live in other areas and places not far from the former location. Notably, I develop an anthropological approach to understand the historical formation of these three localities. Secondly, I analyze some processes of territorialization, which were emerged from the 1980s and had important consequences to these indigenous families throughout the next two decades. This historical dimension is re-appropriated and ressignified in ethnic terms. A third point of my work is the analysis of the construction of territorialities and also the cultural and symbolic dimensions which are formulated by the Tremembé Indians who live in these localities. Therefore, I investigate some cultural traditions and rituals, such as the Torém dance, but I also examine their multiple semantics, which constitute a transversal direction throughout the history understood by the Tremembé of the different social situations I researched. To sum up, there is a process of cultural actualization, which is still going on and presents itself through the ludic sphere as well as their political and religions dimensions, which are usually associated to the ritual presentation of the Torém

Combater as secas e defender as florestas a natureza nos desafios da ciência e da técnica para modernizar o Brasil (1889 a 1934)

In the first decades of 20th century the just instituted Brazilian Republic faced the challenge to modernize the country. Considering that the progress was associated with the exhaustion of the forest reserves and with climatic changes, two big issues were seen as fundamental: To Fight the Droughts and To Defend the Forests; headed by professionals who were dedicated to these ideals. This research starts from the premise that these were the main challenges enforced by nature to the Brazilian development; the general objective was delimited in the search to understand the meaning and the conception of the natural world by this group of professionals who faced the shock between modernizing the country and conserving its natural resources. Aiming to contribute with the construction of the Brazilian environmental history and to bring historical elements to the debate about the environment in the country, the author concentrates his attention to the analyses, the discussions and the actions that preceded the regulation on the use of natural resources and the implementation of the environmental legislation in Brazil, occurred in 1934. The investigation uses as methodological basis the theoretical directions of environmental history, using sources of data still little explored and valued. In such way, it is taken as starting point some published papers about this subject during the period between 1889 and 1934 in two technical magazines the Revista Brazil Ferro-Carril and the Revista do Club de Engenharia. National engineering played a basic role in this process while arguing, projecting and constructing the development. The formulated proposals, after being divulged, had fomented the interchange with other professionals and had favored the advance of ambient questions in Brazil, in the sense to preserve natural resources, to construct more harmonic relations between the society and the nature and to equate the development with the environment preservation

A concepção estrutural como expressão plástica: um olhar tectônico sobre arquitetura em madeira

This work regards to the structural conception as a formal element of design in wood architecture. On this approach, the group of projects studied is formed by some realized works of two important Brazilian architects: Severiano Porto and Marcos Acayaba. The time interval comprises the period from 1971 to 1997, which correspond respectively to the years of the creation of first and the last of the analyzed constructions. The research perspective concerns to the relationship between the parts, the whole and the building techniques adopted in each project. Moreover, the analysis focuses on the structure as the link among the different projectual ideas. Thus, the research method firstly includes a survey of specific bibliographies and documents which refer to the structural conception in wood architecture. Secondly,the buildings are analyzed according to the methods of architectural composition discussed through this work.

A assistência técnica nos habitats do MST e o papel do arquiteto e urbanista

This dissertation is about Architect and town planner inserts in the technical support of the Rural establishment and of the possibilities of changes in their habitat. It also looks for its participation through the production of those spaces with or without its performance through two references cases, in Rio Grande do Norte , one called settlement Eldorado de Carajás and another one called Maria da Paz. At first the process represents the model that was adopted systematically by Incra until the middle of the year 2000 with the sub-contracting of their construction work through small companies. These standardized projects which are executed without registration in the system CONFEA/CREA without demand of professional authorship and of technical responsibility of the work. But the process taken place at Maria da Paz s area was configured as one of the first initiatives that stopped with those practices. Consolidated through a partnership among UFRN MST and INCRA/RN, the Architect s technical support and town planner brought new technician-scientific organization and execution of the soil parcels and its habitat. The participation of UFRN was done through a group of studies in land reform and Habitat (GERAH) being this author and coordinator of the methodological proposal, based on the regressive-progressive method and in the inclusion of the conflict as responsible of the ruptures and transductions both done by Henry Léfèbvre and in the research action approached by Carlos Brandão. Therefore it included the process of social learning and collective production of new knowledge and attitudes in relation to the environment in the process called as attended self management in spite of the transformations happened with this new agent s participation. The people re-located to the new areas that got involved in the process and finished their constructions reelaborating the daily practice of the collective effort passed to the self management without technical support. Years later the implantation of those two experiences our research verified that there is a positive image concerning the Architect and town planner, related, most of all to the conception of the activities, orientation and execution of constructions projects and of acceptance of those professionals to the processes of implementation of the Habitats of the Rural establishments. This dissertation analyses this form of performance, from and beyond these images trying to find the professional, specificities or methodological in such a way to demonstrate the importance of its insertion in the formulation and attendance of the more of 100.000 habitats of Rural establishments of the land reform of the country that correspond to most of the housing social interest in the country side
