Ação pública na formação e transformação do destino turístico de Porto de Galinhas: um estudo dos referenciais no período de 1970 a 2010

The central interest of this thesis is to comprehend how the public action impels the formation and transformation of the tourist destinies. The research was based on the premise that the public actions are the result of the mediation process of state and non-state actors considered important in a section, which interact aiming for prevailing their interests and world visions above the others. The case of Porto de Galinhas beach, in Pernambuco, locus of the investigation of this thesis, allowed the analysis of a multiplicity of actors on the formation and implementation of local actions toward the development of the tourism between the years 1970 and 2010, as well as permitted the comprehension of the construction of the referential on the interventions made. This thesis, of a qualitative nature, has as theoretical support the cognitive approach of analysis of the public policies developed in France, and it has as main exponents the authors Bruno Jobert and Pierre Muller. This choice was made by the emphasis on the cognitive and normative factors of the politics, which aspects are not very explored in the studies of public policies in Brazil. As the source of the data collection, documental, bibliographic and field researches were utilized to the (re)constitution of the formation and transformation in the site concerned. The analysis techniques applied were the content and the documental analysis. To trace the public action referential, it started by the characterization of the touristic section frontiers and the creation of images by the main international body: the World Tourism Organization, of which analysis of the minutes of the meetings underscored guidelines to the member countries, including Brazil, which compounds the global-sectorial reference of the section. As from the analysis of the evolution of the tourism in the country, was identified that public policies in Brazil passed by transformations in their organization over the years, indicating changes in the referential that guided the interventions. These guidelines and transformations were identified in the construction of the tourist destination of Porto de Galinhas, of which data was systematized and presented in four historical periods, in which were discussed the values, the standard, the algorithms, the images and the important mediators. It has been revealed that the State worked in different roles in the decades analyzed in local tourism. From the 1990s, however, new actors were inserted in the formulation and implementation of policies developed, especially for local hotelkeepers. These, through their association, establishes a leadership relation in the local touristic section, thereby, they could set their hegemony and spread their own interest. The leadership acquired by a group of actors, in the case of Porto de Galinhas, does not mean that trade within the industry were neutralized, but that there is a cognitive framework that confronts the actors involved. In spite of the advances achieved by the work of the mediators in the last decades, that resulted in an amplification and diversification of the activity in the area, as well as the consolidation at the beach, as a tourist destiny of national standout, the position of the place is instable, concerned to the competitiveness, once that there is an situation of social and environmental unsustainability

O Litoral e a metrópole dinâmica imobiliária, turismo e expansão urbana na região metropolitana de Natal-RN

The metropolitan regions of Northeast Brazil are being gradually included in a scenario of international investments, which are motivated by the restructuring of both touristic and real-estate sectors. The new capital, real-estate developers and space configurations that result from this process indicate the need for the creation and implementation of public tools which should, at least, allow the mitigation of the urban impacts and environmental losses resulting from this situation. The effects on landscape and on the socio-spatial configuration result from the intensification caused by the dynamism of the "real estate-tourism" sector. There is a regional integration as an expression of the urban expansion of the metropolitan area of Natal. This study investigates the uniqueness of the restructuring and territorial integration of coastal areas and the strategies of the circuit of capital accumulation formed by linking the real estate to tourism. It is intended to increase the understanding about the strategies of tourism, real estate and public policy agents involved in this territorial reconfiguration and in the fund-raising needed for the investments, to understand the existing social and environmental effects and their future trends and also to understand the forms of spatial production as results from the practices of approaching the land transformation and the tourism valorization of the landscape, in a synchronous manner, first in the Northeast region and, as a focal study, in the Metropolitan Area of Natal. Likewise, it is intended to apprehend the current processes of metropolization of the eastern coast of Rio Grande do Norte, in addition to indicate its physical-territorial transformation and the types of projects/developments promoted by the market in the recent period. Based upon analysis undertaken for the Metropolitan Region of Natal RN, this piece of work presents some considerations on possible legal instruments that can be adjusted to the municipalities which are experiencing the impact of this peculiar and recent phenomenon in the region, caused by the arrival of the real estate-touristic capital. It is also intended to point out basic proposals to the forms of public intervention, in a speculative way, starting from a Metropolitan Planning project within a medium and long term

Uma cidade em transformação: a influência da atividade do crediário nas mudanças da paisagem urbana de Tenente Ananias-RN

Studies on the urban landscape and on the changes of the urban space are relevant, since they reveal the economic dynamics and the way of life in the cities. Research on small towns, in particular, can display particular aspects and by so doing broaden the comprehension of this theme. The purpose of this research is to analyze the changes in the urban landscape and in the way of life of the inhabitants of the town of Tenente Ananias-RN that have been taking place since the 1990s up to the present (2013) and which result mainly from the commercial activity of crediário. The study is, therefore, a reflection on the impact of crediário economy on the urban landscape and on the way of life of a small town located in the hinterland of the State of Rio Grande do Norte. For this reason, it was necessary to study the landscape and the way of life found in Tenente Ananias in two moments: a) before the rise of the crediário, a period of time ranging from the town‟s initial emergence until the beginning of the 1990s; b) during the progress of crediário activity, from the beginning of the 1990s, when it starts, up to the present (2013). For this research, primary data (interviews, local survey visits) and secondary data (books, articles, reports, census data) were used. As a result of this study, it was possible to conclude that crediário plays a fundamental role for the explanation of the changes taking place in Tenente Ananias-RN, especially in the urban landscape and in the way of life of people. We have attempted, through this research, to contribute to the studies of a historical, social and economic process related to the urban landscape and space of a small town in the State of Rio Grande do Norte

Caracterização de compósitos Nb-20%cu obtidos por moagem de alta energia e sinterizados por fase líquida

In this work, was studied the formation of a composite of the refractory metal niobium with copper, through the process of high-energy milling and liquid phase sintering. The HEM can be used to synthesize composite powders with high homogeneity and fine size particle distribution. It may also produce the solid solubility in immiscible systems such as Nb-Cu, or extend the solubility of systems with limited solubility. Therefore, in the immiscible system Cu-Nb, the high-energy milling was successfully used to obtain the composite powder particles. Initially, the formation of composite particles during the HEM and the effect of preparation technique on the microstructure of the material was evaluated. Four loads of Nb and Cu powders containing 20%wt Cu were synthesized by MAE in a planetary type ball mill under different periods of grinding. The influence of grinding time on the metal particles is evaluated during the process by the withdrawal of samples at intermediate times of milling. After compaction under different forces, the samples were sintered in a vacuum furnace. The liquid phase sintering of these samples prepared by HEM produced a homogeneous and fine grained. The composite particles forming the sintered samples are the addition of a hard phase (Nb) with a high melting point, and a ductile phase (Cu) with low melting point and high thermal and electrical conductivities. Based on these properties, the Nb-Cu system is a potential material for many applications, such as electrical contacts, welding electrodes, coils for generating high magnetic fields, heat sinks and microwave absorbers, which are coupled to electronic devices. The characterization techniques used in this study, were laser granulometry, used to evaluate the homogeneity and particle size, and the X-ray diffraction, in the phase identification and to analyze the crystalline structure of the powders during milling. The morphology and dispersion of the phases in the composite powder particles, as well the microstructures of the sintered samples, were observed by scanning electron microscopy (SEM). Subsequently, the sintered samples are evaluated for density and densification. And finally, they were characterized by techniques of measuring the electrical conductivity and microhardness, whose properties are analyzed as a function of the parameters for obtaining the composite

Estudo da sinterização de cavacos de aço ferritico

This research studies the sintering of ferritic steel chips from the machining process. Were sintered metal powder obtained from machining process chips for face milling of a ferritic steel. The chip was produced by machining and characterized by SEM and EDS, and underwent a process of high energy mill powder characterized also by SEM and EDS. Were constructed three types of matrixes for uniaxial compression (relation l / d greater than 2.5). The differences in the design of the matrixes were essentially in the direction of load application, which for cylindrical case axial direction, while for the rectangular arrays, the longer side. Two samples were compressed with different geometries, a cylindrical and rectangular with the same compaction pressure of 700 MPa. The samples were sintered in a vacuum resistive furnace, heating rate 20 °C / min., isotherm 1300 °C for 60 minutes, and cooling rate of 25 °C / min to room temperature. The starting material of the rectangular sample was further annealed up to temperature of 800 ° C for 30 min. Sintered samples were characterized by scanning electron microscopy, optical microscopy and EDS. The sample compressed in the cylindrical matrix did not show a regular density reflecting in the sintered microstructure revealed by the irregular geometry of the pores, characterizing that the sintering was not complete, reaching only the second phase. As for the specimen compacted in the rectangular array, the analysis performed by scanning electron microscopy, optical microscopy and EDS indicate a good densification, and homogeneous microstructure in their full extent. Additionally, the EDS analyzes indicate no significant changes in chemical composition in the process steps. Therefore, it is concluded that recycling of chips, from the processed ferritic steel is feasible by the powder metallurgy. It makes possible rationalize raw material and energy by manufacture of known properties components from chips generated by the machining process, being benefits to the environment

Avaliação de um método de cromatografia em fase gasosa head space e estudo da estabilidade do etanol em amostras de sangue

The ethanol is the most overused psychoactive drug over the world; this fact makes it one of the main substances required in toxicological exams nowadays. The development of an analytical method, adaptation or implementation of a method known, involves a process of validation that estimates its efficiency in the laboratory routine and credibility of the method. The stability is defined as the ability of the sample of material to keep the initial value of a quantitative measure for a defined period within specific limits when stored under defined conditions. This study aimed to evaluate the method of Gas chromatography and study the stability of ethanol in blood samples, considering the variables time and temperature of storage, and the presence of preservative and, with that check if the conditions of conservation and storage used in this study maintain the quality of the sample and preserve the originally amount of analyte present. Blood samples were collected from 10 volunteers to evaluate the method and to study the stability of ethanol. For the evaluation of the method, part of the samples was added to known concentrations of ethanol. In the study of stability, the other side of the pool of blood was placed in two containers: one containing the preservative sodium fluoride 1% and the anticoagulant heparin and the other only heparin, was added ethanol at a concentration of 0.6 g/L, fractionated in two bottles, one being stored at 4ºC (refrigerator) and another at -20ºC (freezer), the tests were performed on the same day (time zero) and after 1, 3, 7, 14, 30 and 60 days of storage. The assessment found the difference in results during storage in relation to time zero. It used the technique of headspace associated with gas chromatography with the FID and capillary column with stationary phase of polyethylene. The best analysis of chromatographic conditions were: temperature of 50ºC (column), 150ºC (jet) and 250ºC (detector), with retention time for ethanol from 9.107 ± 0.026 and the tercbutanol (internal standard) of 8.170 ± 0.081 minutes, the ethanol being separated properly from acetaldehyde, acetone, methanol and 2-propanol, which are potential interfering in the determination of ethanol. The technique showed linearity in the concentration range of 0.01 and 3.2 g/L (0.8051 x + y = 0.6196; r2 = 0.999). The calibration curve showed the following equation of the line: y = x 0.7542 + 0.6545, with a linear correlation coefficient equal to 0.996. The average recovery was 100.2%, the coefficients of variation of accuracy and inter intra test showed values of up to 7.3%, the limit of detection and quantification was 0.01 g/L and showed coefficient of variation within the allowed. The analytical method evaluated in this study proved to be fast, efficient and practical, given the objective of this work satisfactorily. The study of stability has less than 20% difference in the response obtained under the conditions of storage and stipulated period, compared with the response obtained at time zero and at the significance level of 5%, no statistical difference in the concentration of ethanol was observed between analysis. The results reinforce the reliability of the method of gas chromatography and blood samples in search of ethanol, either in the toxicological, forensic, social or clinic

Alcoolemia em vítimas fatais de acidentes de trânsito no Rio Grande do Norte empregando cromatografia em fase gasosa - head space

Alcohol is one of the few psychotropic drugs that their consumption has admitted legally and sometimes encouraged by the society. Studies show alcohol as the highest consumption of drugs among young people and society in general, probably because of its availability and easy access. The abuse causes public health problems, which was closely related to the violence, socioeconomic problems and the high number of automobile accidents. Transit is one of the main sectors affected by the effects of alcohol, observing a high incidence in the studies. About half of automobile accidents occurs after the consumption of alcoholic beverage, and the vast majority of cases related to high concentrations of alcohol in the bloodstream. The relationship of drunk with traffic accidents is in fact evident everywhere in the world, including Brazil, where studies have shown a high relationship between alcohol consumption and traffic accidents. This study determined the alcohol in fatal victims of traffic accidents in the state of Rio Grande do Norte and established the profile of this population compared with those found in Brazil and other countries. Samples of blood of ethanol added to fulfillment of the standardization of chromatographic conditions and procedures for the analysis, being employed in the determination of alcohol in blood samples of 277 victims of traffic accidents, collected at the Institute of Scientific Technical Police of Rio Grande do North (ITEP) in the year 2007. The blood alcohol level was determined in these samples correlated with the sex, age and marital status of the victim and the location, day of week and month when the accident occurred, is doing a statistical analysis and outlining a profile of the victims of an accident at transit in the state of Rio Grande do Norte. The parameters of standardization studied ensured the quality of the analytical method and, consequently, to obtain reliable laboratory results. Being given the best temperature for injector (150 ºC), detector (250 ºC) and column (50 ºC) with a flow of gas in the column of 2mL/minutos and analysis of time of 12 minutes. The method was linear in the range of 0.01 to 3.2 g / L (r2 = 0.9989) with average recovery of 100.2% and precision with coefficient of variation less than 15%. The analysis carried out on victims of fatal road traffic accidents, ethanol detected in the blood in 66.43% of the victims and these, 96% showed concentration ≥ 0.2 g / L, 87.73% of victims were male, while 12.27% female. The younger age group (1535 years) was the most involved (52,35%) and most single (55.60%). The accidents occurred with greater prevalence in the day on Monday (27%) followed by Sunday (24,19%) and Saturday (15,52%) and it was found that the prevalence of injuries varied between the different months of the year, and in February (14.4%) and April (10.47%) the months that had a higher number of accidents, however this oscillation showed no statistically significant difference. Also no significant difference was observed between the tracks of concentration found in men and women. The standardized method showed to be efficient, given satisfactorily to the goals of this work, and the high levels of alcohol found in victims of fatal road traffic accidents are consistent with several studies of literature, and the profile of the victim also supported by presenting in its most young adults, male and single

A transformação da Associação de Professores do Rio Grande do Norte (APRN) em Sindicato dos Trabalhadores em Educação (1986-1990)

El estudo que ahora apresentamos habla a respecto ala transformaçión de la Asociación de maestros del Rio Grande del Norte (APRN en sindicato de los trabajadores en educación (SINTE) en el período de 1986 1990. Tratase basicamiente de las razones que llebaran historicamente la APRN la reorganizar sus luchas, su cultura política y el su movimiento reivindicatório; que impulsionaran la construción del próprio sindicato el único de la categoria, após el regime militar em el país especialmente en el gobierno Sarney, y en el ánbito estadual com la resistência la política econômica y la repreción policial del gobierno Geraldo Melo, la época. El estudo también apunta algunas caraterísticas marcantes del contexto histórico de la educación nacional, enfatizando la asención de la escuela nueva en el Brasil en las décadas de 1920 y 1930, inclusive delante del movimiento sindical, controlado por el gobierno Vargas que tênia uma praetica corporativista. Es importante decir que esas características estavan juntas del contexto local, en el rato en que se percebia la primer gestan del prof Anfilóquio Cámara, como el primer presidente de la APRN, al partir de la su fundación (1920), y que tênia um relacionamento bastante estrecho com el poder público estadual de caráter liberal. Habia una discución sobre la abertura política y la atuación política de las clases médias brasileñas ya em 1979, y al mismo tiempo analisabase el desencandeamiento del nuevo sindicalismo en el ABC Paulista, mientras uno movimiento sindical, autônomo y democrático que tênia el objetivo de juntar lãs luchas de los operários dentro y fuera de las fábricas reivindicando basicamiente: la redución de la jornada del trabajo, reajuste de sueldo y condición del trabajo, bien como lãs sus consecuencias para el movimiento de los educadores potigurares. Al hacer en septembre de 1989, el sindicato de los trabajadores en educación del Rio Grande del Norte se desvincula definitivamiente de uma estructura sindical vertical (tradicional), que la ex-APRN herdo al longo de su História del gobierno Vargas, siempre controlada pelo Estado y que en las décadas de 1980 y 1990 fue fortalecido por la CNTE (Confederación Nacional de los Trabajadores en la, educación), principalmente, a partir del Congreso Nacional de Unificación de los Trabajadores en la Educación, realizado en Aracaju/SE em el período de 25 a 28 de enero de 1990 en el sentido tambien de las sus principais reivindicaciones: escuela pública, gratuita y de cualidades en todos los pasos, verbas públicas solamiente para las escuelas públicas, reposición de los reajustes de sueldo, condición del trabajo, sueldo unificado nacional y la eradicación del analfabetismo

Reestruturação do setor industrial e transformação do espaço urbano de Campina Grande PB : a partir dos anos 1990

The central objective of this thesis is studying the changes in the industrial sector of Campina Grande-PB, in the years 1990, about the size of that space and urban sector. The hypothesis that guides this work is that there was a reconfiguration and industrial space in recent years, the result of the restructuring of productive capital and, secondarily, public policies - economic, urban etc. - implemented in the municipality in the years 1990. This reconfiguration industrial meant thepredominance of certain productive segments of the industry and the shift towards urban-industrial areas (industrial districts). This work is guided in these two axes to explain the changes in the industrial campinense and its consequent impact on the urban development of Campina Grande. It is understood by reconfiguration industrial changes in industrial structure, namely the preponderance of one or more productive segments on the other, changing the scenario of production, employment and the number of establishments. In this study, are considered as institutional structures of support and assistance to industry, the various institutions that directly and indirectly, contribute to the development of productive activity. These structures are the first to undergo institutional changes, physical and policies because of intrinsic connection with the industry. The institutional structures contribute to the development of industrial activity and urban development. In Campina Grande, these institutions are important for facilitating the development of certain segments. In this work, sought to identify the current configuration industrial campinense, explaining how the restructuring of production transformed the industry, modifying the urban space in Campina Grande - PB, to direct itself to specific urban areas, from the early 1990

As práticas educativas na saúde da família: uma cartografia simbólica

This qualitative research aimed to understand the educational activities carried out in Family Health Units, of the municipality of Mossoró-RN. It was used symbolic cartography to organize and present data from reality. It started on the approach of Health Education and knowledge transformation practice, aiming at the development of autonomy and responsibility of individuals and healthcare, publicized by the appreciation of the interpersonal relations area established in services, such as educational emancipator practices contexts. Individual and collective interviews were realized, conducted with health professionals and users of ESF, about themes, activities, membership, the difficulties, the potential and the design of health education that permeate everyday Family Health Strategy. From what was apprehended, thematic maps were done with the analysis of educational practices of professionals belonging to the Family‟s Health. Links are built with the wires of conceptions of education reflected on themes and activities of family health teams. The storylines are rebinded by voices about the difficulties and the potential of educational processes for emancipator postures. For users, health education means proper care and information on disease prevention. Professionals understand that it is all information that is given to users, about health, social well-being, economic and general condition of human being as a way of preventing and treating disease. Mark printed on voices denote that activities and themes worked don‟t motivate users enough for their participation, being that physicians and dentists also get excluded themselves from educational practices. Elderly groups are those who get most involved with the activities. The size of the contained area and its seclusion from community make harder the access of users, as well as diminishing the quality of educational actions and links users-professionals. Therefore, the searching for medicines, medical consultations and wish to be well served are trademarks of voices from the users that interconnect with enlightening information and guidelines offered by professionals to users. It brings out practices that need to incorporate the social, the subjective and act with practices of prevention and health promotion, on the basis of lifestyles. The dialogical model, which needs to be approached since planning phase of health education actions could arouse interest of involved groups; promoting a relationship of dialogue and listening; discussing the local reality; stimulating practical methodological dialetics; promoting processes of deconstruction of concepts, values and attitudes, as more necessary than construction, using multiple languages. The defended thesis denotes paths to other studies aimed at understanding a dialogical template committed to exchanges of knowledge, and discover strategies that encourage formation of critical consciousness and the discovery of how is the training of new generations of healthcare professionals to belong to the project of society, in its technical, scientific, pedagogical, ethical, political and humanistic dimensions

O santo do purgatório:a transformação mítica do cangaceiro Jararaca em herói

This research intends to narrate the journey of a simple man who was turned into a saint by a group of believers in Mossoró, west of Rio Grande do Norte. We recognized in the story of José Leite Santana, the "cangaceiro" Jararacá, an appropriated land to build an investigative approach of how characters as different as bandit and saint can be interconnected. From the believers speech, a narrative was created about these detachments of concepts based on the hero myth that is shown here as a part of men´s dealing with death

Dignidade da pessoa humana e medidas sócio-educativas do Estatuto da Criança e do Adolescente

The main goal of this work is to verify the presence of the principle of human dignity, determined by the Constitution of 1988, when Socio Educational Acts from the Statute of Children and adolescent were put in practice, focusing on the treatment designated to the youth whose acts were against the law in the city of Natal, as well as the difficulties to match the legal texts and its reality. It is common knowledge that the law for children and adolescent was based in the principle of human dignity, for its institutes say so. But would the Law match the practice of Socio Educational Acts? Or this law would be an example of good intentions that never left the paper and became reality? First there is an approach on the human dignity principle, with its definition and limitation, according to a theory about the theme. Afterwards it is made a connection between human rights and the principle of human dignity considering historical and social features, for the law is also a reflect of these transformations, we try to show the different laws the country had until today, concerning the children inflicted by poverty and those whose acts were against the law, since the rodas dos expostos, the phase of irregular situation, in which the children were arrested simply because they were beggars, until present time. The theory aspects are shown beside a field research made with the adolescent and staff from CEDUC/Natal, producing a critical view about the subject and showing some solutions for the problems found. At last, it is made a critical analyses of the problems detected on the field research, and, in some cases, a suggestion is given to change the reality
