De volta para os braços da rainha dos céus: migração, memória e festa em Caicó/RN

The present work has as an objective to seize up some particular meanings of the Feast of Sant Ana (The saint which represents the city of Caicó/RN), a central event of the calendar festive-religious of that city, looking for to perceive on how it combines with the symbolic poles sacred: profane through the social bonds that are present there performed and expressed through the social networking and of local belongings. Such bond ties reveal themselves through a very especial manner, through the migration of returning to the feast, when collectively are produced and updated knowledge and codes that reinforce the representation of the local belonging, nominated as being caicoense . We seek on perceiving how the many events of this feast (from a perspective of a religious order as well as laic) acting on a conclusive way to an identity of the re-meaning of that city, especially in its relation with the migrant natives: the sons and daughters that return to the arms of Sant Ana

Análise de retorno de escala e tamanho do mercado no desempenho de equipes de vendas aplicando análise de envoltória de dados DEA: um estudo em empresa de Telecomunicações no Brasil

This Master s Thesis proposes the application of Data Envelopment Analysis DEA to evaluate the performance of sales teams, based on a study of their coverage areas. Data was collected from the company contracted to distribute the products in the state of Ceará. Analyses of thirteen sales coverage areas were performed considering first the output-oriented constant return to scale method (CCR-O), then this method with assurance region (AR-O-C) and finally the method of variable returns to scale with assurance region (AR-O-V). The method used in the first approach is shown to be inappropriate for this study, since it inconveniently generates zero-valued weights, allowing that an area under evaluation obtain the maximal score by not producing. Using weight restrictions, through the assurance region methods AR-O-C and AR-O-V, decreasing returns to scale are identified, meaning that the improvement in performance is not proportional to the size of the areas being analyzed. Observing data generated by the analysis, a study is carried out, aiming to design improvement goals for the inefficient areas. Complementing this study, GDP data for each area was compared with scores obtained using AR-O-V analysis. The results presented in this work show that DEA is a useful methodology for assessing sales team performance and that it may contribute to improvements on the quality of the management process.

Responsabilidade social e competitividade :um estudo sobre a influência de práticas sociais na decisão de escolha de um destino turístico

The work objective was to investigate the influence of social practices social in the choise decision of a tourist destination. For in such a way, a survey with the aid of a questionnaire, was used as being the research instrument. The study used a simple random sample without replacement, due to elements of the population had a equal probability different of zero, to be selected for forming part of the sample. The used collection method of data was personal interview. The data was collected at Augusto Severo International Airport at the moment in which tourists were embarking in return to the residence place or another tourist destination. For determination of sample size, it was considered the tourist who had visited Natal in November and December, 2004, supplied by the Secretariat of Tourism in the RN. The sample for the research was of 403 people. Results showed that the interviewed express the existence of high level of competitiveness in the tourism industry. It was observed that 42.5% of the interviewed believes to exist a very aggressive competition, and 47.5% believed that the competition is aggressive in the tourism industry. 10.4% of the interviewed expressed much interest in knowing about social practices in the tourism industry and 2.8% had not presented any interest in knowing about social practices in the tourism industry. For the interviewed, the travel agency image is a significant item in the choice for a tourist package, because of 35.6% believed that this factor is very important in the choice. 5% of the interviewed only find that little important or that sometimes the travel agency image can be seen as s decisive factor in the tourist package choice

Extração do óleo e caracterização dos resíduos da borra de petróleo para fins de reuso

The petroleum industry, in consequence of an intense activity of exploration and production, is responsible by great part of the generation of residues, which are considered toxic and pollutants to the environment. Among these, the oil sludge is found produced during the production, transportation and refine phases. This work had the purpose to develop a process to recovery the oil present in oil sludge, in order to use the recovered oil as fuel or return it to the refining plant. From the preliminary tests, were identified the most important independent variables, like: temperature, contact time, solvents and acid volumes. Initially, a series of parameters to characterize the oil sludge was determined to characterize its. A special extractor was projected to work with oily waste. Two experimental designs were applied: fractional factorial and Doehlert. The tests were carried out in batch process to the conditions of the experimental designs applied. The efficiency obtained in the oil extraction process was 70%, in average. Oil sludge is composed of 36,2% of oil, 16,8% of ash, 40% of water and 7% of volatile constituents. However, the statistical analysis showed that the quadratic model was not well fitted to the process with a relative low determination coefficient (60,6%). This occurred due to the complexity of the oil sludge. To obtain a model able to represent the experiments, the mathematical model was used, the so called artificial neural networks (RNA), which was generated, initially, with 2, 4, 5, 6, 7 and 8 neurons in the hidden layer, 64 experimental results and 10000 presentations (interactions). Lesser dispersions were verified between the experimental and calculated values using 4 neurons, regarding the proportion of experimental points and estimated parameters. The analysis of the average deviations of the test divided by the respective training showed up that 2150 presentations resulted in the best value parameters. For the new model, the determination coefficient was 87,5%, which is quite satisfactory for the studied system

Entre júbilo e ruína: a perspectiva trágica de Nietzsche

It is investigating why reason Nietzsche affirms, in 1888, when revises his work (Ecce Homo), that to be exactly with The Birth of Tragedy it will be necessary to forget some things , and, in spite of, insist, in the same writing, in naming himself the first tragic philosopher - that is, the opposite and antipode of a pessimistic philosopher . Nietzsche elaborates in The Birth of Tragedy a theory about tragic starting from the opposition and complementarity among Apollo and Dionysian, rationalism and instinct, and in the refusal of the pessimistic perspective. The objective of the dissertation is to discuss how the theory of tragedy modifies due to the rupture with the inspiring of the first moment of the nietzschian philosophy, Schopenhauer and Wagner - maybe the such things to be forgotten about The Birth of Tragedy - and the implications of this rupture, that transforms the philosophy of Nietzsche in dissident of the metaphysical tradition. Like this, it is noticed that there is more continuity than estrangement in what concerns to the definition of tragic, just announced in 1871. By the sentence of the eternal return to the concept of will of power Nietzsche elaborates a tragic perspective, marked by the Dionysian celebration of the life, also acted through the pessimism dionisiac , defined in Gaya Science's § 370 (1881-2), and of the sentence of the love fate, enunciated in the §276 of the same work; all those concepts, discussed in this research, concentrate, decisively, the acceptance idea and statement of life, or more precisely, the decline of the tragic hero, between joy and ruin

Análise sísmica usando transformada de Curvelet

Oil prospecting is one of most complex and important features of oil industry Direct prospecting methods like drilling well logs are very expensive, in consequence indirect methods are preferred. Among the indirect prospecting techniques the seismic imaging is a relevant method. Seismic method is based on artificial seismic waves that are generated, go through the geologic medium suffering diffraction and reflexion and return to the surface where they are recorded and analyzed to construct seismograms. However, the seismogram contains not only actual geologic information, but also noise, and one of the main components of the noise is the ground roll. Noise attenuation is essential for a good geologic interpretation of the seismogram. It is common to study seismograms by using time-frequency transformations that map the seismic signal into a frequency space where it is easier to remove or attenuate noise. After that, data is reconstructed in the original space in such a way that geologic structures are shown in more detail. In addition, the curvelet transform is a new and effective spectral transformation that have been used in the analysis of complex data. In this work, we employ the curvelet transform to represent geologic data using basis functions that are directional in space. This particular basis can represent more effectively two dimensional objects with contours and lines. The curvelet analysis maps real space into frequencies scales and angular sectors in such way that we can distinguish in detail the sub-spaces where is the noise and remove the coefficients corresponding to the undesired data. In this work we develop and apply the denoising analysis to remove the ground roll of seismograms. We apply this technique to a artificial seismogram and to a real one. In both cases we obtain a good noise attenuation

O reino encantado do sertão: uma crítica da produção e do fechamento da representação do sertão no romance de Ariano Suassuna

Based on the relation history, literature and space, this work examines the production and the closing of the representation of the hinterland in the Romance d A Pedra do Reino of the paraiban writer Ariano Suassuna. Inspired by method proposed by deconstructionist by Jacques Derrida, our reflection decomposes the writing scene of Suassuna by means of it s tracks to interpret the operation of the representation of the space-hinterland for the speech of the writer. Being thus, we present the elements chosen for Suassuna to weave an identification it s with this space-hinterland, taking a priori as a sentimental place and of familiar origin . The construction of this relation of belonging in great is measured grounded for a familiar memory entangled in the context politician who culminated in the Revolution of 1930 and that he resulted for the writer in the death of father. Suassuna launches a look on the identity and the Brazilian culture that guided in the tradition concept it searchs to deny the gift grounding its speech in the return to the past, a past order . Specifically in it s romance we notice to exist the fusing of these tracks in the production of a representation of the hinterland that it intends to close a concept of this space and its culture. Soon, the idea of kingdom sends to the space of the enchantments manufactured in infancy and retaken by the intellectual radical who in the anxiety of honor the father figure, does not save efforts in constructing a space representation that, over all, either faithful the representation that it searchs to trace of proper itself. Under one it marks of universality , the hinterland-kingdom of Suassuna if discloses eurocentric in the measure where it perpetuates discurse the filiation of the European cultural traditions.

O mundo criado pelas imagens: paisagens e espaços coloniais na obra do holandês Frans Post

The aims of this dissertation is to study formation of the Dutch view seeing the colonial scenery in screens by Frans Post, as well as, to perceive a colonial world constitution through landscape paintings by him with his natural and human representation. The artist was the first to portray South American views, after he landed in Pernambuco with retinue of Dutch governor of colony, John Maurice, Prince of Nassau-Siegen. Post, by his 24 years old, was designated to represent for Dutch people their colony. The text reflects on visual construction of natural and human aspects in landscapes by Dutchman and how that aspects were included in colonizer imaginary about the strange world of America. European (Dutch) look about their conquered possessions in the New World was charged with exoticism and imagination. In order to understand that view, it`s paramount to study imaginary pictures reared by Frans Post, on his return to the Netherlands, and notions of landscape and exotic, wild and unspoiled nature which the Dutch people had when they thought about the Dutch colony in America. Our principal (visual) sources of research are six paintings: Vista da Sé de Olinda (1662), Vista das ruínas de Olinda (undated), Engenho (undated), Engenho (1660), Vista da cidade Maurícia e do Recife (1653), e Paisagem com rio e tamanduá (1649), all these canvases were painted when Frans Post returned to Europe. We seek to work through a methodology that focuses on investigation of primary visual and textual material, because these textual and pictorial representations reflect the 17th-century colonial view of colonial history themes of the - here called - Dutch America

Caracterização estatística de processos sísmicos via Distribuição Generalizada de Pareto. Estudo de caso: João Câmara-RN

The work is to make a brief discussion of methods to estimate the parameters of the Generalized Pareto distribution (GPD). Being addressed the following techniques: Moments (moments), Maximum Likelihood (MLE), Biased Probability Weighted Moments (PWMB), Unbiased Probability Weighted Moments (PWMU), Mean Power Density Divergence (MDPD), Median (MED), Pickands (PICKANDS), Maximum Penalized Likelihood (MPLE), Maximum Goodness-of-fit (MGF) and the Maximum Entropy (POME) technique, the focus of this manuscript. By way of illustration adjustments were made for the Generalized Pareto distribution, for a sequence of earthquakes intraplacas which occurred in the city of João Câmara in the northeastern region of Brazil, which was monitored continuously for two years (1987 and 1988). It was found that the MLE and POME were the most efficient methods, giving them basically mean squared errors. Based on the threshold of 1.5 degrees was estimated the seismic risk for the city, and estimated the level of return to earthquakes of intensity 1.5°, 2.0°, 2.5°, 3.0° and the most intense earthquake never registered in the city, which occurred in November 1986 with magnitude of about 5.2º

Centros de especialidades odontológicas: avaliação da atenção de média complexidade na rede pública da Grande Natal

The Specialized Dental Care Centers (CEO) were developed to provide specialized dental care to the population, given the accumulated needs of health since the past. They must operate as units of reference for the Oral Health Team of the Primary Care, complementing the dental procedures performed at this level of attention. This study aims to assess the performance of CEOs of the Grande Natal Health Region as a strategy of Secondary Care consolidation in oral health through users, dentists and managers. For this to try to identify factors about access, hosting and satisfaction with the service, the actions developed in these centers, integration between the CEOs and the Basic Health Units (UBS), considering the reference and counter reference. Data were collected through semi-structured interview, conducted in four CEOs, among 253 users, 31 dentists and 4 managers. It was submitted to descriptive statistical analysis and to content analysis by software ALCESTE 4.5. The results revealed that the specialties of prosthesis, endodontics and surgery were the most sought by 38.2%, 23.7% and 21.7% of respondents, respectively. It was noticed that among users aged 18 to 30 years-old the greatest demand is for the specialty of endodontics (44.4%) and over 50 years for prosthesis (76.4%). There is a weakness in the reference and counter reference between UBS and CEO, because part of users goes directly to the centers without going before to the Primary Care and the majority does not want to return to the dentist of Health Unit. Satisfaction with care was reported by 90.9% of users, because they resolved the problems needed and were welcomed by the team. But the delay in care was the main factor for not satisfaction. For most dentists, some users could solve their problems completely in Primary Care, which shows the existence of unnecessary referrals to the CEOs, however they consider the existence of limiting factors in UBS that compromise the service. Most dentists revealed that some users do not get to CEOs with the basic dental treatment done, and some of them do not counter reference users. It can be concluded that the studied CEOs are being resolutive for those who access them, offering necessary care for the population, and if they don t account with this service, will encounter obstacles to resolution of problems, ranging seek care service in particular, in another public sector, or even giving up treatment. However, it is perceived the need of professionals training to understand the importance of the reference and counter reference, to that they can better serve and guide users. It is also important that cities offer better conditions to UBS and CEOs, so they can work together, with complementary actions of oral health, seeking full care, aiming for better resolution to the users' health problems

No pulsar da clínica: a repetição e as produções corporais de uma criança

This study investigates the Repetition of movements shown in a stereotypical case of a child three years old. In line with the psychoanalysis model of search, this work presents fragments of the clinic process, the locus for the observation of repetitive, ritualized and choreographically movements of this child who used not to speak. The contrast between their movements and the issuance of a word verbalized at the end of the treatment caused the following question: repetition in this child production would be a reproduction of the same or would be directing for the difference? In the psychiatric speech, the stereotypes are listed as diagnostic criteria for certain mental disorders. In the psychoanalysis studies a question about the psych nature of ritualistic gestures apparently without purpose or direction is included. Thus, the route followed was the reading of the theoretical concept of repetition in the psychoanalytic works of S. Freud and J. Lacan. With Freud, the repetition is linked to the transfer and resistance. In that context, when it appears in act, in the place of the talk, it constitutes a particular way of remembering. But the existence of a force in the psychic apparatus that acts independent and involuntarily of the Principle of pleasure (the repetition compulsion) subsidizes the discovery of Freudian pulsion of death that is the tendency to return to itself. In the Lacan reading, the function of Repetition is magnified, as it fulfils two functions: the automaton - reminders of repetitive signs, and that the service of tiqué - the meeting of the subject with his lack constituent. In this sense, repetition is not simply a reproduction, but the search for new, the difference, caused by the lack of continuity that pushes the circuit. Finally, the clinic process and the theoretical readings made the comprehension of the child repetitive and choreographically movements and the pronouncement of a "good-bye", full of meaning. This repetitive scenario which is full of questions, by this very nature, insists in remains inconclusive

O psicólogo e os serviços de acolhimento institucional para crianças e adolescentes

The Shelters are responsible for caring for children and adolescents whose families or guardians are temporarily unable to fulfill his role as care and protection. The activities to be developed by psychologists in these services are greatly important for the elaboration and development of political- pedagogical project of the same, and for reasons pertaining to the present and future of children and adolescents received judgments. The psychologist puts up the challenge of contributing to a better care of children, also cooperating with the implementation of the new care standards of childcare. The aim of this study was to investigate the role of the professional psychologist in assistance to children and adolescents in 13 Shelters in the Metropolitan Region of Natal/RN. For both set out to make visits to the institutions to know how it is organized the field work of the psychologist, his routine work and activities developed. Nine psychologists interviewed according to a semi-structured interview script. The data analysis is supported by the theoretical aspects of dialectical materialism historical and theme content analysis was used. Results were presented from three angles: psychologists and institutional framework; activities, resources and methods of work; psychologists and legal frameworks of the Institutional Hospitality. The study points out the recent entry of the psychologist in Shelters, combined with considerable turnover of these professionals. This work has been organized through the Individualized Service Plan, prioritizing the return to family of origin. Moreover, in general, perform joints with the service network, reporting, individual consultations and follow-adoption processes . Staff members, however, feel a lack of specific and continuing training on special protection, including due to the distance between the proposed theory and practice. It was thus observed a movement of psychologists distance themselves from welfare or repressive practices, however the structural difficulties of services and lack of continuing education appear to limit the development of a performance focused on the transformation of the reality of children and adolescents treated and their families

A humanização no parto e no nascimento: os saberes e as práticas no contexto de uma maternidade pública brasileira

The practice of medicine related to the gestational processes tend to be organized according to the context and the place of work, being thus dependent of the conditions both social and economical, and of the physical structure and the functionality of the services. The high mortality rate in this process has diminished, since 1986, the study made by the World Health Organization (WHO) as to the technical aspects and the social inequalities that influence this situation in different geographical contexts. This culminated recommendations that proposed the reorientation of the dynamical practice of medicine, with a focus on the safety of maternities. Brazil adopted, in the year 2000, the suggestions of the OMS, emphasizing the humanization as the main reason for these actions. However, this discussion tends to not consider the problems caused by the social inequalities and the epidemiological and social conditionings that define the actions of the Unified Health System (Sistema Único de Saúde SUS). In this area, this research seeks to analyze the practices, cares taken, and the universal symbol that promotes and rewards the assistance to the birth of children by the SUS. Besides the analysis of the public documents that deal with this subject, an ethnographic study was developed in a maternity in Natal/RN, considered a model of humanization after receiving the Galba de Araújo prize in 2002. In this stage, the methodological strategies were observed, and the focus of the individual interviews with workers and users of this service. In the analysis of the data, it became evident that the different professional workers and women who gave birth, tend to show concern of the standards the delimit production and reproduction of the practice of medicine, as they favor the absence of a critical posture of the actions destined to the population. Besides this, if became evident that the institutional difficulties associated to the economical, cultural, and political problems also difficult the involvement and the reflection of the workers in favor of assisting changes of the process. There is also a utilization of a perspective prescriptive of humanization in the everyday life of the social workers, without reflection of its meaning. Some workers present, in their statements, a preoccupation with the social and economical aspects that affect the practice of medicine, and with the limitations of the humanization discourse that disarticulates the necessities of those involved in the process of formation, and soon tend to return to the discussion of humanization while a kind practice characterized by the minimization of the interventionist actions. Now the users of the system show themselves before the dynamic of the services, submitting themselves to what is offered while assistance, without questioning and/or reflecting about their usual shortages. Therefore, to think of changes in the know and do of the practice of medicine destined to the birth of children implies reflection on the quotidian production of these practices and of the social contexts that influence the process of assistance in the practice of medicine. Herein it would be possible to predict the appropriation, by different workers concerning their exasperations and necessities, making them active in the pursuit of their rights as citizens

Sistema especialista fuzzy para dimensionamento de bombeio mecânico

Despite the emergence of other forms of artificial lift, sucker rod pumping systems remains hegemonic because of its flexibility of operation and lower investment cost compared to other lifting techniques developed. A successful rod pumping sizing necessarily passes through the supply of estimated flow and the controlled wear of pumping equipment used in the mounted configuration. However, the mediation of these elements is particularly challenging, especially for most designers dealing with this work, which still lack the experience needed to get good projects pumping in time. Even with the existence of various computer applications on the market in order to facilitate this task, they must face a grueling process of trial and error until you get the most appropriate combination of equipment for installation in the well. This thesis proposes the creation of an expert system in the design of sucker rod pumping systems. Its mission is to guide a petroleum engineer in the task of selecting a range of equipment appropriate to the context provided by the characteristics of the oil that will be raised to the surface. Features such as the level of gas separation, presence of corrosive elements, possibility of production of sand and waxing are taken into account in selecting the pumping unit, sucker-rod strings and subsurface pump and their operation mode. It is able to approximate the inferente process in the way of human reasoning, which leads to results closer to those obtained by a specialist. For this, their production rules were based on the theory of fuzzy sets, able to model vague concepts typically present in human reasoning. The calculations of operating parameters of the pumping system are made by the API RP 11L method. Based on information input, the system is able to return to the user a set of pumping configurations that meet a given design flow, but without subjecting the selected equipment to an effort beyond that which can bear
