Natal também civiliza-se: sociabilidade, lazer e esporte na Belle Époque Natalense (1900-1930)

Les initiatives du gouvernement ayant pour finalité une réorganisation de la structure urbaine de la ville au début du XXème siècle reflètent le désir vécu par les membres de l'élite locale d'encadrer Natal dans les moules des grands centres urbains de la même période. Les élites désiraient transformer Natal dans une ville moderne. Dans ce but, le gouvernement s'est engagé dans la reformulation de quelques espaces physiques de la ville. Néanmoins, il fallait aussi d autres que les transformations urbaines, la ville devrait passer par des réformes sociales. De cette façon, ces groupes ont créées des nouvelles institutions et espaces de sociabilité qui affirmeraient la capitale de l'État comme une ville moderne. Les institutions formelles avaient un rôle imortant dans la construction de cette nouvelle ville convoitée par l'élite locale. Ainsi, à travers celles-ci, se diffusaient des nouvelles pratiques sociales qui seraient reflétées dans les espaces urbains. Dans des places tels, des cafés, des clubs et associations sportives, l'élite se distinguait du populaire. Dans ces places, leurs pratiques étaient légitimées, en contrepoint avec les pratiques populaires. C était dans les clubs et par les activités pratiquées par leurs membres que les idéals de l'élite circulaient, c était par là que l'élite se formait et se transformait. De cette façon, les aspirations d'un groupe social reflétaient dans l'organisation sociale des espaces de la ville

Em nome da cidade vencida: a São Luís republicana em José do Nascimento Moraes (1889 1920)

Cette dissertation a pour but d´analyser la ville de São Luís do Maranhão pendant la Première Republique, d´après le roman Vencidos e Degenerados, de José do Nascimento Moraes, publié en 1915. À partir des rapports entre l´Histoire et la Littérature, nous nous intéressons à la façon dont l´auteur écrit l´histoire d´une ville qui, après la fin de l´esclavage et l´installation de la Republique, conserve des anciens préjugés de race et reste plongée dans l´immobilité economique. Le roman fait partie d´un ensemble d´oeuvres scientifiques et littéraires d´une géneration connue sous le nom de Novos Atenienses (nouveaux athéniens), laquelle discutait la crise économique et culturelle vécue par le Maranhão au tournant des XIXe et XXe siècles. Le discours formulé par les nouveaux-athéniens comprennait des eléments nostalgiques associés au culte des lettres envisageant la conquête de la réconaissance littéraire et le désir d´adapter la ville de São Luis aux modèles de progrès et modernisation de la période républicaine. Dans ce contexte, Moraes introduit les thèmes liés à la discrimination raciale qui demerait après la fin de l´esclavage, qu´il considérait un obstacle au progrès de la capitale de Maranhão, et aussi la cause des pérsecutions littéraires dont il était victime. On a analisé le roman en cherchant compreendre les rapports entre les individus et les rapports qui´ils entretienent avec les spaces de la ville, à partir de questions d´ordre littéraire, raciale et urbaine. En guise de conclusion, la narration de l´oeuvre est dévellopée de façon que la ville, peuplée de gens de couleurs, sert à legitimée l´oeuvre littéraire de Moraes, dont le nom a été oublié dans les principaux cercles littéraires de la capitale pendant la période examinée

Guerra e identidade: um estudo da marcialidade no Heimskringla

The goal of our dissertation is to study how the Scandinavian writings produced a Norwegian identity of warlike ideals in a compilation of Icelandic sagas known as Heimskringla and has parts of its content focused on storytelling about a troubled time of Scandinavian monarchies rising between the 8th and 11th centuries, which is called the Viking Age. The Heimskringla, also known as The Circle of the World is a set of writings based on Icelandic oral memory about the Norwegian kings and the conception of a Norwegian territory. While we investigated the relationship between the members of royalty, their companions and the Scandinavian people, we delineate the relationship between memory, identity and war. Our study points out how the Scandinavian war produces, in its storytelling, proper spaces, in socio-political relations among the participants, in the organization of its conflicts or the location of war activities, where places are transformed into essential points in these narratives. The war is both a place of identity statements and a space of practices, necessary for the strengthening of royal power

A coleção mossoroense e a construção dos mitos: Dix-Sept Rosado, o herói imolado

This research comprises a study on the values and ideals attributed to Dix-sept Rosado, by the Coleção Mossoroense journal. Local researchers demonstrate how the Coleção Mossoroense constructs an image of Mossoró, forming in the members of the city an identity with the place, a social cohesion or creating one forms to see and to say about the Mossoró city. The Coleção Mossoroense, through Vingt-un Rosado together with its family, established a form of seeing and identifying of the Mossoró s population with the city, just because it associated and it was, at the same time, a movement at the same time social (civic parties for example), political (the domination of the Rosado s family) and cultural (the books and theatrical parties about the city). The conjunction of the Coleção Mossoroense as and with a social movement, cultural and political was capable to establish a social identity, a subjective constituent . With this background, it was possible to make a study of the image attributed to Dix-sept Rosado, by the Coleção Mossoroense, through an analysis of the inherent discourse in the works by Bakhtin (1989) and Bourdieu (2000), of and on Dix-sept Rosado in the Coleção Mossoroense based on. The image of Dix-sept Rosado was constructed by the Coleção Mossoroense after its death, and the responsible for this was Vingt-un Rosado, which was the chief-editor of the Coleção Mossoroense up to 2006, year of its death. The Coleção Mossoroense built an image of Dix-sept Rosado as an enterprising man, progressive and innovator, of great capacity of leadership and oratory (a conductor of the crowds ), popular and charismatic, an honest and dynamic politician. This image made by the Coleção Mossoroense, although when enhancing in surplus the qualities of Dix-sept Rosado have as objective to transmit an image of a heroic personage, it has some relation with the reality. Dix-sept Rosado was a man identified with its locality. This can resemble a regional nationalism. The attitudes of Dix-sept Rosado must be understood inside of a broader social context, of a time marked by the populist politics. Qualities also appreciated and developed inside of a specific historical context and determined both national and locally. The Coleção Mossoroense enhances the qualities of Dix-sept Rosado so that the current politicians of the Rosado s family can establish a link of continuity in its contemporary political practice

Escolha de parceiros na adolescência

Mate choice is a component of sexual selection. Trying to understand the patterns of this process, several studies have emphasized the adaptive value of sexual differences and their influence on the assessment of the market value. The pattern for adults presented on the scientific literature, which is based on the preference for certain characteristics, shows that men search a partner who shows high value of fecundity and fertility, thus looking for partners with the ability of being pregnant and nursing their offspring. On the other hand, women look for partners with high socioeconomic status, which is strongly associated with the ability to protect and provide resources for them and their offspring. Surprisingly, there is few works that investigated the mate choice patterns during the beginning of the period of sexual differentiation on the morphological, physiological and behavioral traits. The aim of this study was to investigate mate choice patterns in adolescence in order to describe their preferences and contribute to the understanding of human reproductive behavior. Took part of this research 1,232 students from educational institutions of Natal, Brazil, and visitors to the Scientific, Technological and Cultural Fair UFRN. In the Experimental Study 1, we applied a questionnaire to evaluate the importance of certain characteristics, assessed the degree of romantic involvement and real and ideal partners age preference. In the Experimental Study 2, we did a survey of characteristics considered relevant and evaluate the importance of these characteristics in mate choice. The Experimental Study 3 brought an investigation of mate choice patterns based on self-assessment of adolescents, evaluating ideal partner for a short-term and long-term relationships and actual partner. We found that adolescents are motivated to live romantic experiences. We also observed a preference for partners of similar age to that described for adults. Finally, we found similarities and differences in the preferences for characteristics in real and ideal partners in relation to the adult pattern. In addition, we observed high similarity on the self-assessment and assessment of real and ideal partners. We suggest that in the mate choice, adolescents are similar to young adults in some aspects but not all. Our results show the relevance of the reproductive behavior investigation in this human developmental period and reinforce that further studies should contribute to the understanding of human behavior in terms of ontogenetic development and their evolutionary history.

Percepção do mercado romântico e influência do contexto nas preferências românticas entre universitários

Men and women express different preferences for ideal romantic partners. These preferences seem to vary with the level of involvement and commitment expected for the relationship and the perceptions people have about themselves. The current work was developed to expand the findings related to this subject, investigating the market perception of romantic relationships and the effect of context on self-assessment and preferences for romantic partners. For this purpose, 753 undergraduate, Brazilian and American, were enrolled between March 2010 and November 2012 and took part in at least one of the four studies that compose this research, performing the assessment of specific stimulus-subject descriptions. Studies one and two addressed Brazilian and American samples to respectively describe female and male expectations on human mating market. It was observed that individuals from both the genders expect positive assortative mating within couples, that each trait is not evaluated independently, and, in addition to biological predispositions, factors as environmental local constrains and cultural values may also affect mating expectations. The contrasts between the samples showed that Americans valued physical-attractiveness and social-status in describing the same-gender subjects and their expected partners, while Brazilians valued social-skills. Another expectation was also identified for both genders: physically attractive women and men of high-status were expected to be paired to each other. Study three addressed males and females expectations regarding which characteristics are most relevant in ensuring desirable partnerships for same-gender individuals. The results showed that men and women can be grouped together by having similar expectations. However, the group mainly composed of men considered status characteristics as the most important attributes, while the groups mostly composed of women indicated that social skills or physical characteristics as the most important in appealing to a desirable partner. Finally, study four investigated the effect of social comparison on self-perception and mate preferences, revealing that individuals were aware of the attributes valued by the opposite-gender and that self-perception was affected by the attributes of other people. In sum, this work evidenced that romantic relationships can be interpreted as a biological market and that the value of the attributes in the romantic mating marketplace are associated with reproductive relevance of the characteristics.

Preferências e escolhas românticas entre universitários

Several studies have found different patterns of preferences to men and women for short term and long term relationship romantic partners. It is known that the preferences vary with the sex of individuals, the expected involvement level of the relationship and according to the perceptions that subjects have about themselves. In the present study, we investigate whether the preferences typically founded for sexes are also founded between Brazilian undergraduate students. We also investigated if the individuals choose partners in accord of the sex preferences and if the ideal preferences are really expressed in real choices. For these investigations, 370 undergraduate students described profiles of an ideal partner for a short-term and a long-term relationship, through the joint evaluation of nine characteristics. Each ideal s profile has been described over three simulations, in which the amount of points available to be invested were limited and gradually reduced. After the descriptions of these profiles, the participants described the current or previous partner (if they were not in a relationship) and performed a self-assessment with the same characteristics used in the description of preferences. Overall, the results obtained in several countries were observed in Brazil. For short-term relationships men prioritize physical attributes and women value physical and personal attributes. For long-term, personal traits gained in importance on masculine preferences and women emphasized personal traits and the partner disposition to acquire resources. We also identified similar preferences profiles for both sexes and that the romantic preferences reflect similarities with the own individual s characteristics, in addition to the typical sexual preferences expected for the Parental Investment Theory. When evaluated their real partners, men considerate them more physically attractive than themselves but less intelligent, good humorous and ambi tion/willing to work. Women, in turn, described their partners as good as them. Finally, we observed equivalence between characteristics of the subjects and those of its partners, this effect being more pronounced among men. The last partners were described only as less sincere. The interpretation of the most part of our results was possible from evolutionist s and socio-cultural s explanations and was discussed under the two perspectives. We conclude this study stressing that the traditional romantic preferences occur in Brazil and that the sex, the kind of relationship and the vision that people have about their own characteristics affect the preferences, which are expressed in the real partner choices

A ação do psicólogo na assistência social: interiorização da profissão e combate a pobreza

A pobreza, como uma das manifestações da questão social , é elemento constitutivo do padrão de desenvolvimento capitalista, extremamente desigual, em que convivem acumulação e miséria. Nas últimas décadas, sob a égide do ideário neoliberal, verifica-se um incremento em políticas de combate à pobreza no Brasil, de caráter focalizado e compensatório, tanto por meio de ações diretas de transferência de renda, quanto pelo fortalecimento de serviços e programas voltados às populações pobres, com a estruturação do Sistema Único de Assistência Social, hierarquizado em Proteção Social Básica e Especial. A participação do psicólogo nas equipes profissionais do CRAS constitui um importante elemento para a discussão da inserção desse profissional no campo das políticas sociais no Brasil, considerando os limites estruturais postos pelo caráter compensatório dessas políticas, e a construção de estratégias que possam resultar em uma mudança efetiva nas condições de vida das camadas mais pobres da sociedade. Aliado a isso, por meio do ingresso na política de assistência social, um número significativo de profissionais psicólogos passa a atuar em cidades pequenas e médias, fora dos tradicionais centros urbanos, constituindo um movimento de interiorização da profissão . O objetivo do presente trabalho é analisar a ação profissional do psicólogo na assistência social no contexto nas políticas de combate à pobreza em municípios do interior do Rio Grande do Norte. Realizou-se entrevistas semiestruturadas com psicólogos atuantes nos CRAS de 17 municípios de pequeno e médio porte do estado. As informações foram sistematizadas com auxílio do software QDA Miner v. 3.2. A perspectiva defendida neste trabalho refere-se à funcionalidade das práticas psicológicas no contexto das políticas de combate à pobreza brasileiras na atualidade, ao reforçar os ideais neoliberais de naturalização da questão social e responsabilização dos indivíduos pela sua condição social, além de, em grande parte, desconsiderar as particularidades e singularidades que marcam os territórios de ação. Todavia, é possível depreender alguns modos de ação profissional que estão na contramão dos mais frequentemente encontrados nesse campo. Esses modos se revelam no cotidiano do CRAS como formas diferentes de compreensão do saber fazer profissional, resultados de um posicionamento político e de uma formação profissional que buscam romper com o tradicionalismo e conservadorismo da Psicologia e do campo da assistência social

Em defesa da reforma psiquiátrica :por um amanhã que há de renascer sem pedir licença

Insanity was victim of several arbitrary acts perpetrated on behalf of the science. Psychiatric reform constitues an important movement which has attempted to rescue dignity and humanity in the treatment of mental disorder patients. Some countries have advanced in the implement of substutive models that work on the construction of a new social place for madness. The model of attention to mental health in Brazil has also suffered extensive modifications due to the wearing out of the psychiatric hospital model. In Santos, a town in the State of Sao Paulo, we have found a landmark in the development of an anti internment politics, through the creation of a dail care service, including psychosocial assistance. It is in this context that it has been founded in Natal, Rio Grande do Norte, the NAPS and CAPS ( Nucleus and Centres of Psychosocial Attention), municipal strategies that put into effect the law # 10.216/2001, which estabilishes the gradual extinction of psychiatric hospitals. This work has the purpose of carrying out a study about the historical process of psychiatric reform implantation in the State of Rio Grande do Norte, emphasizing the actors involved in process, their trajectory, achievements, improvements, and the movement s perspectives of achieving the ideal of reinstating mental disorder patients. In order to accomplish this purpose, it was necessary to understand the process occurred at the Municipal Secretary s Office for Health, since 1992, for it was the impelling experience towards the reflections about the psychiatric reform in the State of Rio Grande do Norte. The instruments used for this work were documentary analysis, through reports, legislation and handbooks, as well as the staments of people involved in this process. Through the statements analysis, we attempted to estabilish the social actors identity, their perception, emphasizing congruences and incongruences concerning the history of psychiatric reform in the State of Rio Grande do Norte. It is also analyzed the contribution of Psychology in this process, which has become a protagonist in the struggle for the rights of mental disorder patients

Preparação de resinas de poliuretana à base de óleo de mamona e dietanolamina

The aim of this work was the preparation of polyols from reactions between castor oil and dietanolamine to increase the hydroxyl content and the network degree in the products to application in electronic devices. The polyols and the mixtures obtained were characterized by nuclear magnetic ressonance. Castor oil (CO) is a natural triglyceride - based polyol possessing hydroxyl groups, which allow several reactions that produce many different products. Among them are the polyurethanes (PU), which have been considered an ideal product for the covering of electricelectronic circuits, due to their excellent electrical, shock-absorbing, solvents resistance and hydrolytic stability properties. About 90% of the fatty acids present in the castor oil are ricinoleic acid (12-hydroxyoleic acid), while the remaining 10% correspond to non-hydroxylated fatty acids, mainly linoleic and oleic acids. The chemical analysis of castor oil indicates a hydroxyl number of 2.7. In this work, a polyol was obtained by the reaction of the CO with diethanolamine (DEA), in order to elevate the hydroxyl value from 160 to 230 or to 280 mgKOH/g, and characterized by nuclear magnetic resonance (NMR) 1H and 13C (Mercury 200). The polyadition of the resulting polyol with isophorone diisocianate (IPDI) was carried out at 60°C, and the reaction kinetics was followed by rheological measurements in a Haake RS150 rheometer. The electrical properties were determined in a HP LCR Meter 4262A, at 1.0 Hz and 10.0 KHz. The chemical analysis showed that the polyols obtained presented hydroxyl number from 230 to 280 mgKOH/g. The polyadition reaction with IPDI produced polyurethane resins with the following properties: hardness in the range from 45 shore A to 65 shore D (ASTM D2240); a dielectric constant of 3.0, at 25°C (ASTM D150). Those results indicate that the obtained resins present compatible properties to the similar products of fossil origin, which are used nowadays for covering electric-electronic circuits. Therefore, the PUs from castor oil can be considered as alternative materials of renewable source, free from the highly harmful petroleum - derived solvents

A educação informal para o consumo infantil e juvenil na televisão e na mídia

The consumption has become a major pillar of modern capitalism and at the same time, one of the factors that relate to social inequality. Karl Marx developed the theory of historical materialism which maintains a history of society determined by class struggle and the! exploitation of man by man. Considered to be overtaken by those who believe that Marxism is synonymous with real socialism, the Marxist ideals seem more present than in the Western world which each individual takes the individualization (loss of sense of public and collective) and the alienation by the work. Weassumed we could work on these issues in student education, even in elementary school, through questioning of the consumer society, with the criticism of television and the media, the main promoter of the current sense of consumption, as an initial step that could lead to future autonomy of theindividual. The theory of ideology and ideas of Paulo Freire's liberating education theory permeated the experience that happened as a participant observation of groups in the discipline of sociology in the unit 2 of the Colégio Pedro II in Rio de Janeiro, the state capital, an institution under the direct administration Ministry of Education. Wehave found fertile ground in which the students were able to understand and question the meaning of advertising media

Identificação e comparação entre controle preditivo com modelo não linear e PI sintonizados com PSO em sistema de separação gravitacional de águia-óleo

The separation methods are reduced applications as a result of the operational costs, the low output and the long time to separate the uids. But, these treatment methods are important because of the need for extraction of unwanted contaminants in the oil production. The water and the concentration of oil in water should be minimal (around 40 to 20 ppm) in order to take it to the sea. Because of the need of primary treatment, the objective of this project is to study and implement algorithms for identification of polynomial NARX (Nonlinear Auto-Regressive with Exogenous Input) models in closed loop, implement a structural identification, and compare strategies using PI control and updated on-line NARX predictive models on a combination of three-phase separator in series with three hydro cyclones batteries. The main goal of this project is to: obtain an optimized process of phase separation that will regulate the system, even in the presence of oil gushes; Show that it is possible to get optimized tunings for controllers analyzing the mesh as a whole, and evaluate and compare the strategies of PI and predictive control applied to the process. To accomplish these goals a simulator was used to represent the three phase separator and hydro cyclones. Algorithms were developed for system identification (NARX) using RLS(Recursive Least Square), along with methods for structure models detection. Predictive Control Algorithms were also implemented with NARX model updated on-line, and optimization algorithms using PSO (Particle Swarm Optimization). This project ends with a comparison of results obtained from the use of PI and predictive controllers (both with optimal state through the algorithm of cloud particles) in the simulated system. Thus, concluding that the performed optimizations make the system less sensitive to external perturbations and when optimized, the two controllers show similar results with the assessment of predictive control somewhat less sensitive to disturbances

Desenvolvendo e gerenciando compostagem de resíduos sólidos urbanos: para geração de renda e repasse de tecnologia à acrevi

Nowadays, as well as in the past decades, the dumping of biodegradable organic waste in landfill is common practice in Brazil, as well as in most parts of the world. Nevertheless due to its rapid decomposition and release of odors, this practice hamper’s the operation and implementation of a recycling system. These facts encouraged our research to find an efficient system for the management of organic waste, not only for the use of official workers responsible for managing these wastes, but also for non-governmental institutions. The Recycling for Life Community Association – ACREVI (Associação Comunitária Reciclando para a Vida), together with the municipal authorities of Mossoró-RN, Brazil, have assumed the social role of collecting and recycling solid waste produced by most of the local population. However, it was observed that the organic waste it collected was not receiving any treatment. This present work aims to make compost with mixed waste (green waste and organic household), and then do chemical analysis of the material in view to use the waste as organic fertilizer. The objective being: to share the knowledge acquired by putting it into a very simple language accessible to people with little education. The experiment was conducted at ACREVI, Mossoró (RN), and the compost was obtained following the method "windrow", forming three cells (I, II, III) with conical shape, dimensions of 1.6 meters and 2.0 meters in diameter for cells I and II, and 1.0 meters high and 2.0 meters in diameter for cell III. The process was accompanied by analysis: CHN elemental, a variation of cell temperature, humidity, pH, TKN, bulk density, nutrients and heavy metals. Stabilized organic compounds reached the C/N ratio of 10.4/1 cell I and 10.4/1 in the cell II in the cell, showing how good soil conditions, with potential to improve the physical properties of any soil and pH acid soils, has presented the cell III at the end of the process the C/N 26/1, is a high ratio may be associated with the stack size III, thus changing the optimal conditions for the occurrence of the process. The levels of heavy metals in the analyzed compounds were lower than those established by the SDA normative instruction, Nº 27, of 5 June, 2006. The use of pruning trees and grass are used in small-scale composting, while generating a quality compost in the final process, it also created an important condition for a correct sizing of the composting piles. Under the studied conditions it is not advisable to use cells with a height of 1.00 m in height and 2.00 m in diameter, as these do not prevent the rapid dissipation of heat and thus can not be a good product at the end of composting. The composting process in the shed of the association and the preparation of the primer enabled the development of an alternative technology to generate income for members of ACREVI.

Evolução termocronológica do sistema de falhas Senador Pompeu-CE

The region of the Senador Pompeu Shear Zone (SPSZ), in the North Tectonic Domain of the Borborema Province (BP), has its recent history associated with to South Atlantic Ocean formation event at the Jurassic. A lot of geologics models have discussed about crustal axis elevation in local scale and large scale (Borborema Province), relative to importants regionals tectonics directions of it. The identification and the relationship among this surfaces, stepped in many topographyc levels by tectonics mecanisms, is dificult because of the erosion process on it. Over there, sedimentary deposits is complex and it has not biostratigraphyc record in continental deposits. The analysis metodology on apatita fission-track, in the region of the SPSZ, purpose the more knowledge about morphotectonics mecanisms of the area and the impruvement of its morphotectonics models. For this, it was moleled the age and thermal history of the 11 apatites samples collected on both sides of this shear zone, taking relationships among other results of the thermochronology studies in the BP. Based on the thermal studies in this search, the region of the BP developed on two distint cooling events, separated for one period of relative stabilited. The first episode occur between 130 and 90 M.y., has been began when the samples cross the 120°C isoterm for last time and fineshed at 70°C. The second moment of the cooling process was began about 30 M.y., when the temperature was 90°C, from this to the equlibrium with present surface temperature at 30°C. Some evidences indicated a relacionship between thermal episodes and uplift events of the regional relief. The fundaments of the interpretation was based mainly on comparatives studies among results of the thermochronology analysis and geologics studies about BP. Nóbrega et al.(2005), e.g., on studies about the Portalegre Shear Zone, got similar results on SPSZ, with some details relative to local tectonic activity. Morais Neto et al. (2000) interpreted two importants cooling events in the BP based on their regional studies, that can be associated to regional uplift events. When Assine (1992) studied the stratigraphyc sequences of the Araripe Basin, in the south of Ceará state, conclude that the abrupt return to continentals condictions from the last sedimentar sequency (albiano-cenomaniane) indicate a regional uplift of the NE region of the Brazil at the 100 M.y., in the Albiano Intermediate/Superior. This ages are compatible to termal model of the SPSZ. This two periods of the thermal history of the BP are completely registered in the apatites samples just one age groups of the fission-track, that it is the most ancient age groups. This one suggest it has happened in response to heating before 75 M.y and it has erased the last report of the first moment relief evolution of the BP. The NNE-SSW and E-W structure reativation can have created ideal condictions for heating and local elevations of the geothermal gradients. The equilibrium between the apatites temperatures of this groups and the regionais temperatures took place about 50 M.y., when the samples of the two ages groups had a simillar evolution to present surfaces temperatures

Sobre pedras, entre rios: modernização do espaço urbano de Caicó/RN (1950/1960)

thèse de maîtrise, qui a été idealizée et exécutée à partir de la réunion et les relations dialogiques établies entre la géographie et l'histoire, et l'espace et le temps, a considéré l'environnement urbain comme le thème général et, comme la référence empirique, l'espace urbain de Caicó, incrusté dans les terres semi-arides du Sertão do Seridó Potiguar, plus précisément à la mi-sud de l'État du Rio Grande do Norte. Dans cet espace, à travers de recherche des fragments de mémoires acquis de diverses sources historiques, on a tenté de faire des investigations sur les transformations urbaines qui ont eu lieu dans la ville au cours des années 50 et 60 du XXe siècle. Ces transformations, dans l espace urbain de Caicó à un moment du pic de l'activité de développement de coton, reflétaient et conditionnaient les propres projets de modernization urbaine qui représentants des élites locales eurent conçu avec l'objectif de la construction d une ville idéal dans les regions isolées du Seridó: moderne, civilisé, progressive et capitale régionale du Seridó. Pour cette construction, les nouveaux équipements et services urbains ont passé du plan imaginaire à l espace réel, installés dans plusieurs quartiers de la ville en transformant le paysage urbain. Face à cette situation, cinémas, magasins, station de radio, énergie électrique, institutions de l'éducation, téléphonie, maison de soins infirmiers, usine de bénéficiement de coton, banques, politiques urbaines, hygiéniques et sanitaires, modes de comportement, sociabilités urbaines distincttes, parmi d'autres éléments géographiques se sont institués à travers la réalisation de certains idéaux de progrès social et dans un esprit de modernité urbaine, dans de nouveaux espaces et pratiques inventés, tramés et éprouvés sur les rochers et entre le cours d eau au milieu d'un quotidien urbain marqué par ruptures et permanence de certaines coutumes et habitudes antiques et de certains paysages et environnement ridé
