O papel do centro histórico na cidade: um estudo comparativo entre João Pessoa e Tours

In the contemporary scene, it is conspicuous that the patrimony and the culture have assumed privileged positions in urban policies, presenting themselves as instruments for transforming and shaping the aspect of cities. In the plot line of such glowing trend, the competitiveness among cities has drawn more attention, for at present such urban centers garner an image that makes them suitable for economic purposes, thus more likely to attract investments and tourists. In the spotlight of such stage, the cities become notable actors, directed by policies of urban rehabilitation. In such plot line, the historical centers gain more visibility and are converted into venues for staging the spectacle of everyday life. Overlapped in this process of producing images, the phenomenon of gentrification recrudesces. Thus, the discussion threaded about the patrimony gains strength in urban studies, keeping a close relationship with the ways of perceiving the cities nowadays. This work is based on the principle that the historical centers are engendered and fond by urban policies, working as transforming instruments of city perceptions and living. In that sense, the way how the historic center and the valuation assessed to old buildings are comprehended by the inhabitants is largely guided by urban policies that outline a sellable image of the city. In the light of such elaborations, an ethnographic research was made with focus on two different contexts, namely: the historic centers of João Pessoa (Brazil) and Tours (France). It was done in a comparative perspective, for it allows us to trace the main specificities of each situation in order to highlight the similarities and distinctions about the two regions mentioned above. The research aimed at apprehending how the pair redevelopment-abandonment engendered by the urban policies influence on the process of revaluation of historical centers by dwellers and to what extent there are convergences regarding such kinds of interventions, as an object of policies of urban and touristic development in Brazil and France. In order to make this work – besides the abundant bibliographic review carried out in libraries of several universities and institutions in Brazil and France – dwellers, merchants, teachers, representative people of public agencies and former residents of the historic centers of both cities were interviewed. In Tours, immigrants/Portuguese descendants were interviewed, point that greatly contributed to the understanding of the historic center before Vieux Tours renewal and restoration. Moreover a rich research on Archives and Public Agencies was done, as well as investigations on newspaper and articles on the Internet. Thus, in the context of the ethnography in historic centers, it was possible to notice that both realities reveal similarities in a comparative analytical framework

Expansão imobiliária na cidade de João Pessoa, no período de 2009-2013: um caso de formação de bolha?

The housing boom recorded in recent years in the city of João Pessoa contributed decisively to the increase in housing supply across the all territory. This advance, however, was accompanied by a significant increase in property prices, which in itself generates enormous expectations on the support of the same medium and long term. From this apparent frame heating the housing market of this Capital. This study empirically examined whether this enhancement configured a typical process of bubble formation between the years 2009 and 2013 in this part of Capital. The empirical price dynamics of the housing market , was based on the indicators of price, rent and cost developed by Bezerra et al. (2013). The results of these local indicators increase the degree of confidence in the hypothesis seen, whatever, that the movement of prices in the main districts of the city of João Pessoa is a real estate bubble

Contribuições à estratégia de controle sem detecção de harmônicos aplicada a um filtro ativo de potência paralelo

The conventional control schemes applied to Shunt Active Power Filters (SAPF) are Harmonic extractor-based strategies (HEBSs) because their effectiveness depends on how quickly and accurately the harmonic components of the nonlinear loads are identified. The SAPF can be also implemented without the use of the load harmonic extractors. In this case, the harmonic compensating term is obtained from the system active power balance. These systems can be considered as balanced-energy-based schemes (BEBSs) and their performance depends on how fast the system reaches the equilibrium state. In this case, the phase currents of the power grid are indirectly regulated by double sequence controllers with two degrees of freedom, where the internal model principle is employed to avoid reference frame transformation. Additionally the DSC controller presents robustness when the SAPF is operating under unbalanced conditions. Furthermore, SAPF implemented without harmonic detection schemes compensate simultaneously harmonic distortion and reactive power of the load. Their compensation capabilities, however, are limited by the SAPF power converter rating. Such a restriction can be minimized if the level of the reactive power correction is managed. In this work an estimation scheme for determining the filter currents is introduced to manage the compensation of reactive power. Experimental results are shown for demonstrating the performance of the proposed SAPF system.

Estimação de potência em tempo real utilizando a transformada wavelet

The goal of the power monitoring in electrical power systems is to promote the reliablility as well as the quality of electrical power.Therefore, this dissertation proposes a new theory of power based on wavelet transform for real-time estimation of RMS voltages and currents, and some power amounts, such as active power, reactive power, apparent power, and power factor. The appropriate estimation the of RMS and power values is important for many applications, such as: design and analysis of power systems, compensation devices for improving power quality, and instruments for energy measuring. Simulation and experimental results obtained through the proposed MaximalOverlap Discrete Wavelet Transform-based method were compared with the IEEE Standard 1459-2010 and the commercial oscilloscope, respectively, presenting equivalent results. The proposed method presented good performance for compact mother wavelet, which is in accordance with real-time applications.

Topologia de gerador de distúrbios elétricos baseada em conversores de potência

Electrical disturbances such as voltage sags, interruptions and voltage unbalances might cause serious problems for the end-user and for the companies of generation and transmission of energy. Few years ago, those companies have been using methods and equipments of protection to avoid the disturbances’ presence or to mitigate their effects on the power system. Disturbances generators are used to analyse the behavior of electrical and electronic equipments affected by disturbances. The analysis of those failures allows the development of appropriated protection equipments. In this paper, the development of a disturbances generator based on power converters is presented. The disturbance generator developed is able to generate some symmetrical disturbances, such as: voltage sags, voltage swells and harmonic distortion. The control strategy used in the disturbance generator is based on discrete and repetitive control. The steps of the design of the control and of the filter used for reducing harmonic in the output, are detailed in the text. Are presented the obtained results on computational simulations and the obtained results on laboratory tests.

Perguntou o juiz ao tutor pela pessoa deste órfão: os magistrados na ordem sócio educacional do Seridó (século XIX)

This work has the objective to analyze the presence of justice, embodied in the orphans of judges, the encouragement, guidance and custody of minor heirs of the Village of Currais Novos, the area called Seridó of Rio Grande do Norte, especially with regard to education in the century XIX. Aims the meaning of the performance of judges in education and their practices, whereas this figure had a power that went beyond its mere function, but played a political role, taking responsibility for guarding and protection of property left by families of the Imperial period. The study focuses on the set of notary offices documents, inventories, sharing, self accounts and orders, belonging to the District of Currais Novos Forum in the period between the years 1822 to 1829. Finally, the conclusion demonstrates how Judges controlled the education of orphans, through tutors, and it is used for this purpose, the account acts as a procedural mechanism and documentary of its judicial activity.

Emoções, documentos e subjetivação na construção de transexualidades em João Pessoa/PB

This research aims to understand how the affective components involved in transgender relations with documents constitute specific ways in which these people recognize themselves and build their bodies and their paths, their life projects and their relationship with others. We understand that the documents, if the personal identification or those produced by social movements, legal actors and health and the State, are experienced by trans people beyond administrative functions that are initially thought, but also involve a series of emotional experiences mark their subjective processes, in how these people produce themselves and design in the world their sociality networks. We elected as research field two institutions located in the city of João Pessoa (Paraíba State), noting the intense institutional movement, political, social in favor of the rights of transexuals that have occurred in that city in recent years. Thus, the Rights Reference Centre for LGBT and Fight Against Homophobia (Espaço LGBT) and Health Clinic of Transvestites and Transexuals (Ambulatório de Saúde de Travestis e Transexuais) were the spaces where we find our interlocutors and analyze their experiences with the documents noting two key aspects: the search for first name change in the civil registry and the relationship of trans people with documents produced by the health policies and services such as protocols, records, receipts and psychiatric reports. We realized that although there is disagreement about the perception that our interlocutors have on the documentation that regulates health services, all reported experiencing embarrassment in social situations when you have those who make use of a document that is not consistent with the performance and “social face” taken. In addition to the reports of embarrassment, we saw that the discussion of social distress and trauma has grounded the platforms of social movements, public policy, legal processes and become “narratives of pains” that present strong potential micro-political on demand for rights to “trans people”.

Assistência em cuidados paliativos a pessoa idosa na atenção primária a saúde

This study aims to understand the significance of palliative care for the elder health care professionals working in primary health care. Descriptive study of qualitative approach. Conducted in three health units of the Family and a core of support for Health, the Felipe Camarão neighborhood, District of Natal Health West, RN. Of the 25 participants, 19 are professionals of the Family Health Strategy and six of the Center for Support to Health, the majority being women, with minimal professional work experience, a year in primary health care. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte, under CAAE no. 43895815.4.0000.5537. There were individual interviews between July and September 2015, with the use of questionnaire containing open and closed questions on the topic of study. Our results were recorded in MP4 and transcribed into written language, and analyzed using the open coding process medium in which the categories were interpreted and identified, followed by axial coding, where categories were developed and systematically related. Three categories emerged: enhancement of elder health professionals in palliative care, behavioral health professionals across care in palliative care in primary care and disjointed Meaning between palliative care and health professionals. The categories were interpreted and analyzed by the theoretical framework of social phenomenology of Alfred Schütz. Regarding the valuation of subjective perception of professionals, it is clear the issue of the complexity of multiple relationships through various aspects of his central task: focus a philosophy of the world's reality, namely a phenomenology of natural attitude; Before the professional behavior were identified: the discovery and depth of assumptions through the structure, and meaning in a common sense, and at the meaning of the disconnection between the health professionals-including that reality imminent can be represented by individuality special interest of the experience. It follows that health professionals understand there is a difficulty facing the assistance in palliative care to the elderly in primary care, and this difficulty, characterized by the complexity of social interactions across the joint teamwork. Although, I believe that the articulation between the teams, work and family, is essential for the subsequent improvement of care in palliative care favoring the health context surrounding the Elder.

Os possessivos de segunda pessoa em cartas de leitores de jornais brasileiros dos séculos XIX e XX

Based on the theoretical and methodological presuppositions of the theory of language variation and change (cf. WEINREICH; LABOV; HERZOG, 2006 [1968]), it is described and analyzed in this article the process of variation/change concerning the second person possessive pronouns in letters from readers of Brazilian newspapers from the XIX and XX centuries. These letters feature a portrait of the Brazilian press from the South (Santa Catarina), Southeast (Rio de Janeiro) and Northeast (Bahia and Rio Grande do Norte) regions in each century and are part of the Project for Brazilian Portuguese History‘s (PHPB) printed common minimal corpus. The point of departure of this work is the idea that the use of variant forms of expressing second person possessive pronouns – teu and seu – results from the interaction characterizing the varied social roles performed by the letters‘ senders. Arranging communicative units, which gather elements/features denoting time and space, conditioned and determined by socio-historical and cultural aspects, the readers‘ letters, turn out to be a promising research field under the light of this paper. More specifically, In the row of presented results in studies about the pronominal system in the diachroneity of/in Brazilian Portuguese (PB) (FARACO, 2002; LORENGIAN-PENKAL, 2007; CALLOU; LOPES, 2003; LOPES; DUARTE, 2003; MENON, 2005; ARDUIN; COELHO, 2006; LOPES, 2009; MARCOTULIO, 2010), the results featured in here point at different usages of the possessives, noticing the coexistence of the forms teu/tua and seu/sua strongly conditioned by the socio-discursive nature of the readers‘ letters in the course of the centuries and through different regions.

Corpo, força e potência: Nietzsche e Spinoza no pensamento de Deleuze

This dissertation aims at showing the importance of the Nietzsche s and Spinoza s philosophy in Deleuze thought, about body, force, and potency concepts. The search starts from Deleuze texts around two authors of his inspiration, reaching understand in the plan of immanence of the relationship between concepts and the way life as ethics and political affirmation. The first goal is the concept of rhizome; propose by Deleuze in what manner to walk the ways traced by philosophers and at the same time to create self ways. The second chapter examines the body in Nietzsche as force s relations. Find to show the genesis of the force in its determination as relative quantity strong or weak, and as absolute quality active or reactive; and for other side the genesis of the force from two poles of the will to power affirmation or negation, examining the consequences for life and thought. In the third chapter explained the definitions of body in Spinoza. The body, in Spinoza, defines itself complex relation of movement and repose, velocity and slowness and by it s to affect and be affecter s power. Find to show understanding the mediums for to amplify the power of to exist or the potency of to act, in what manner ethics of to live. The fourth chapter makes one parallel between the war and the thought in the constitution of socials body and collectives agenciamientos, for understand in the fifth chapter the body as war s machine of the thought, from the relationship between nomad way life and war s machine showed in Tractate of Nomadologia. Wait like this to show the importance of the ethics and political thought than affirm the existence in the world through active force from that body s power.
