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

Brincadeira do reisado na comunidade Cipó, Pedro II PI: mediação cultural, tradição e modernidade

This research studies the tradition of epiphany in the community of Cipó de Baixo, which belongs to the city of Pedro II, in the state of Piauí. Readings were made seeeking to emphasize the processivity of the play that navigates between permanence and change. The study starts with a social context of the community, in dialogue with the life history of the owner of the epiphany, Raimundo Milú: strong figure who, along with his family networks, as well as networks of patronage and friendship, struggles for the resistence of the play. The description of the ceremony of Kings, with its constituent parts, punctuates the remarkable character of Cipó community epiphany. This detailed understanding of the play favors the understanding of some of the social vines that serve as the basis for the warp of this cultural practice: modernization vine, where we explore the general motivation of Cipó community epiphany transformations - modernity; family and community exchange vine, which describes the scheme that holds the permanence of the play; masculinity vine, explains the strong gender system that crosses Cipó community epiphany; reinvented tradition vine, where we locate the uniqueness of Cipó community epiphany tradition and its dialogues with modern dynamism; conflict between generation vine, depicts the differences between generations and how they contribute to the dialogue between the traditional and the new; theatrical spectacle vine, describes the play as a performative activity. Thus, we build a social scheme that analyzes the play of Kings of Cipó community as a whole, where change and continuity plan a cultural plot on their own

A questão do petróleo em terras indígenas: uma análise constitucional à luz do desenvolvimento sustentável

Recognizing the need to preserve a national ethnic minority, the Constitution, inspired by the pluralistic values of the Constitutional Law State, stipulated a series of rights and guarantees for the conservation of indigenous cultural singularity, disciplining in article 231 the Indians right to maintain their social organization, customs, languages, beliefs and traditions, as well as safeguarding the rights to the lands they traditionally occupy, and the exclusive use of the wealth existing in them, premise of ensuring their physical and cultural continuity, breaking decisively with the paradigm the assimilation of the Indian national civilization. However, despite the Indian policy of ethnic and cultural preservation, the Constitution allowed the exploitation of minerals in aboriginal territory, incorporated herein hydrocarbons, provided they meet certain predetermined requirements, leaving it to the legislature the discipline of ordinary matter. However, this law has not yet been published, with some projects in the National Congress, leaving thus precluding the indigenous subsurface oil exploration until the enactment of enabling legislation. Meanwhile, this paper carries out an integrated analysis of the constitutional protection of ethnic and cultural uniqueness of indigenous peoples, Convention Nº 169 of the International Labour Organization and the bill presented by Deputy Eduardo Valverde, in an attempt to consolidate sustainable development practices in the sector, through developing a system of social and environmental responsible oil exploration, aligning with national energy needs to maintain a balanced environment and preservation of socio-cultural organization of a minority so weakened and beaten over five centuries of domination

Regime constitucional do direito privado das organizações religiosas

In Brazil, constitutional clauses regarding religious freedom have concrete applications in Private Law. Church-State Law, or "Ecclesiastical Law of the State," studies the legal principles which may be applicable to religious activity, exercised individually and collectively. The study of Church-State Law in Brazil lacks a thorough introduction to the constitutional and civil aspects of religious organizations: such an introduction is the main end of this work. Following a brief introduction, the main aspects of religious freedom and the principle of private autonomy as it concerns religious organizations are explained. A careful introductory analysis of Church-State Law in Brazil is thus developed: (1) the historical aspects, including a detailed account of the relations between Catholicism, the established religion up to 1889, and the government; (2) the current constitutional principles, as presented in the text of the federal Constitution of 1988, regarding the rights and claims of religious organizations; (3) how the same constitutional principles are to be used in the interpretation of Private Law (especially the Civil Code of 2002), fostering and preserving the uniqueness of religious organizations in the Brazilian legal system. A brief complementary chapter presents some aspects of the legal position of religious institutions in three other nations whose constitutional documents have influenced the current Brazilian federal Constitution (France, Spain, and the United States)

Uma ação reflexiva sobre o processo de (re)escrita de textos: a prática pedagógica da professora Maria

T he reflexive action on the process of texts (re)writing, central topic of this study, is still a challenge within the elementary school. What made this issue a special theme of study was the fact that the chosen focus is based on a lived experiences with (re) writing activities where the uniqueness of the professional practice would be transformed into a place of knowledge production, offering theoretical and a practical support to a teacher, in order to understand the interactive nature of language as a space for recovery of the individual (as a historical, social, and cultural being). The empirical field research, structured in the light of assumptions of qualitative research into the action research format, was a public school in Bahia, in a third grade classroom. The instruments of data collection were open questionnaire, semistructured interviews, observations with video recording, documentary analysis of texts produced by students, and reflective sessions. The objectives that supported the research study were: 1) Investigate, in the pedagogical action of teacher Maria, activities on the writing process, 2) Interact with the teacher, in the form of action inquiry to: a) reflect on the procedures for theoretical and methodological development of reflective practice on the process of the (re) writing of the text, b) intervene in the construction of didactic situations that enable the learning and the development of reflexive actions in the (re) writing of texts. To accomplish these goals, it was established as a commitment a dialogic communication with the protagonist, providing reflection sessions so she could examine her teaching practices. The most relevant theoretical arguments to the establishment of this research came from the theoretical and methodological approaches of Bakhtin s theory of enunciation-discourse (2003, 2004) and Vygotsky s socio-interactionist theory (1989, 1998), as it is believed that both theories, through a paradigm shift, in which the constitution of the individual and the participation of others in the actions of analysis and reflection on the language, would give opportunities for internalization and construction of knowledge. The systematic and critical pondering led the participating teacher into reviewing her teaching praxis, compelling her to promote a more insightful understanding of the writing process of her students. That experirence brought into evidence three categories of actions: 1) actions that reflect the technical rationalism, 2) actions that reflect an emancipatory metamorphosis, and 3) actions that reflect empowerment and awareness. The results confirm that the action / reflection on the process of the (re) writing of a text has a dimension of increasing levels of awareness and self criticism, reproducing other meanings for teaching praxis

Educação inclusiva: práticas de professores frente à deficiência intelectual

The present work is a survey of pedagogical practices of teachers who experience the daily school with students with Intellectual Disability (ID) in their classrooms, considered inclusive. The study was conducted in academic year 2010 in a municipal school in Natal-RN, aimed at investigating the pedagogical practices developed by the participating teachers as well as its view of the front of Intellectual Disabilities students who are inserted in the initial years of Elementary School. In methodological choice, considering the nature of the phenomenon, we chose the qualitative approach and the case study method. The observation and semi-structured interview were used as procedures, which contributed to a significant collection of data in an attempt to answer the objectives. The study subjects were selected by convenience and were formed into two teachers from Elementary School I, linked to the public educational system, which volunteered to collaborate in this research. The analysis of the observations and of the speeches made possible build pedagogical considerations on the action with students with Intellectual Disabilities in a regular school. The results point to a practice covered with a traditional pedagogy, with a few adjustments, although there is an initial process of change, what we observe in the classroom and captured in the words, because, at various times, we saw an interest in developing a pedagogy of Freire. One aspect that caught our attention refers to the formative action at school for these teachers. We found its incipiency, because this does not happen in a systematic way at school. Throughout the years investigated, the teachers had no access to any form of training neither to any form of specialized monitoring. We realize that there is still a concept of Intellectual Disability that makes difficult to "see" this student as a human being having learning opportunities. The aspects that interfere in the formation hinder the development of a pedagogical practice that meets the uniqueness of its customers and promotes a truly effective school inclusion, consistent with social rights proclaimed in this century. We believe in the irreversibility of the inclusive process initiated a few decades ago and that obstacles to the practice of teaching students with ID are visible and possible to overcome if they are turned into challenges for all those who compose the school, the municipal education system and those who build public policies for inclusive education

Obtenção de Propriedades Físico-Químicas de Misturas de Hidrocarbonetos em Baixa e Alta Pressão Visando a Caracterização e a Modelagem

The composition of petroleum may change from well to well and its resulting characteristics influence significantly the refine products. Therefore, it is important to characterize the oil in order to know its properties and send it adequately for processing. Since petroleum is a multicomponent mixture, the use of synthetic mixtures that are representative of oil fractions provides a better understand of the real mixture behavior. One way for characterization is usually obtained through correlation of physico-chemical properties of easy measurement, such as density, specific gravity, viscosity, and refractive index. In this work new measurements were obtained for density, specific gravity, viscosity, and refractive index of the following binary mixtures: n-heptane + hexadecane, cyclohexane + hexadecane, and benzene + hexadecane. These measurements were accomplished at low pressure and temperatures in the range 288.15 K to 310.95 K. These data were applied in the development of a new method of oil characterization. Furthermore, a series of measurements of density at high pressure and temperature of the binary mixture cyclohexane + n-hexadecane were performed. The ranges of pressure and temperature were 6.895 to 62.053 MPa and 318.15 to 413.15 K, respectively. Based on these experimental data of compressed liquid mixtures, a thermodynamic modeling was proposed using the Peng-Robinson equation of state (EOS). The EOS was modified with scaling of volume and a relatively reduced number of parameters were employed. The results were satisfactory demonstrating accuracy not only for density data, but also for isobaric thermal expansion and isothermal compressibility coefficients. This thesis aims to contribute in a scientific manner to the technological problem of refining heavy fractions of oil. This problem was treated in two steps, i.e., characterization and search of the processes that can produce streams with economical interest, such as solvent extraction at high pressure and temperature. In order to determine phase equilibrium data in these conditions, conceptual projects of two new experimental apparatus were developed. These devices consist of cells of variable volume together with a analytical static device. Therefore, this thesis contributed with the subject of characterization of hydrocarbons mixtures and with development of equilibrium cells operating at high pressure and temperature. These contributions are focused on the technological problem of refining heavy oil fractions

Refletindo dificuldades de aprendizagem de alunos do ensino médio no estudo do equilíbrio químico

This research intends to identify the main conceptual mistakes committed by High School students when studying Chemical Equilibrium and also how the didactic books can influence in their formation. For the data - collecting we applied 150 questionnaires with 11 open questions e 4 restricted ones. Students from three different private schools in Natal-RN were used in this survey. The questionary about the book analysis tried to understand how the subject has been boarded, making it easier or not for the knowledge building. The books were chosen by being usually the most used ones at the chemistry classes in the schools in town. On the didactic book analysis we evaluated 12 items that tried to identify the clarity with which the books would bring up the subjects, the contextualization of the exercises, the analogies used, the amount and the quality of exercises, the connections between the subjects, and the retaken of important concepts. The questionary given to the students tried to get their knowledge about the concepts related to Chemical Equilibrium. The main mistakes found were: the definition of the state of equilibrium in a chemical reaction, the constant, the double headed arrow, confusions between mass and concentration, the representation of a microscopic reaction in equilibrium, partial pressure and total pressure, and the function of the catalyser. The results demonstrated a lot of insecurity or lack of knowledge about the subject when it was realized that there was a big number of blank questions and a considerable percentage of questions with conceptual errors. We concluded that those errors could be eased or even avoided if the didactic books and the teachers boarded the contents in a more conceptual form with the application of a largest number of good quality exercices, watching the building of definitions by the students, avoiding this way the formation of wrong concepts

Foucault e a arte do cuidado de si: uma nova possibilidade de Discussão para a formação continuada de professores de língua inglesa

This thesis proposes a new thinking on the English teacher and their continuing education, leaving the picture emerging of a new professional, who is producing and being produced. From this perspective, I present an analysis of self writing of thirteen student-teachers, teachers on how they position themselves to be discursively constituted as subjects in the context of continuing education. As part of Applied Linguistics, the theory and method that supports the analysis of data are articulate key elements of Foucault notions, namely:The care of the self, seeking their connection with one another and care of and the self writing. In the theoretical notions of these elements are implied notions of others, such as speech, ethics, technology of the self, subject and truth. (Foucault, 1984, 1995, 2004c, 2006), and questioning the ethics of the subject. I propose to examine selected excerpts from the self writings of student teachers with a specialization in Teaching and Learning the English Language, seeking linguistic processes in the material production of subjectivities.In order to analyze the process of subjectivation, I examine the discursive statements of selected cuts, aiming to learn more specifically, the points of identification and fragments of the uniqueness of the teachers, showing how they care for themselves and reflect upon them in building their subjectivity from the technologies of the self, to occupy the position of English Language teachers. The results show that, in the exercise of self writing, the subject falls, and a practice of asceticism, discursively construct her/his subjectivity

O mercado imobiliário e a reinvenção da Ribeira, Natal - RN: verticalizar para renovar?

The real estate dynamic originates new spatial forms, which can determine new uses and new places. We tried to analyze this work, the spatial transformations in the Ribeira district, Natal / RN, due to the advancement of the housing market that is gradually transforming the landscape with the introduction of new types of housing, especially by verticalization. The verticalization of the neighborhood occurs almost at once, changing the local landscape. Notwithstanding this process, given the rapid growth of Natal in the last two decades and the strategic location of the neighborhood, it is pertinent to note that, if not the process of vertical integration, perhaps the neighborhood had been at the mercy of other urban interventions and other approach the real estate market. The research used as instruments interviews with actors who work in the property market in the town and representatives of organizations that have implemented major legislation in the area, the Instituto de Patrimônio Histórico e Artístico Nacional (IPHAN) and the Secretaria de Meio Ambiente e Urbanismo (SEMURB) as well as photographs on the area, in order to verify this new configuration that has been consolidated in the district. To support the theoretical discussion, there was a documentary and bibliographical research. In this way, the object of study of this search sees the uniqueness of urban renewal in the district of Ribeira and its relationship with the historic preservation laws and incentives for residential occupation in the neighborhood, especially regarding the vertical building

Formação de caudas maxwellianas no Contexto da rotação estelar

In this Thesis, we analyzed the formation of maxwellian tails of the distributions of the rotational velocity in the context of the out of equilibrium Boltzmann Gibbs statistical mechanics. We start from a unified model for the angular momentum loss rate which made possible the construction of a general theory for the rotational decay in the which, finally, through the compilation between standard Maxwellian and the relation of rotational decay, we defined the (_, _) Maxwellian distributions. The results reveal that the out of equilibrium Boltzmann Gibbs statistics supplies us results as good as the one of the Tsallis and Kaniadakis generalized statistics, besides allowing fittings controlled by physical properties extracted of the own theory of stellar rotation. In addition, our results point out that these generalized statistics converge to the one of Boltzmann Gibbs when we inserted, in your respective functions of distributions, a rotational velocity defined as a distribution

Teoria cinética não extensiva: efeitos físicos em gases e plasmas

The standard kinetic theory for a nonrelativistic diluted gas is generalized in the spirit of the nonextensive statistic distribution introduced by Tsallis. The new formalism depends on an arbitrary q parameter measuring the degree of nonextensivity. In the limit q = 1, the extensive Maxwell-Boltzmann theory is recovered. Starting from a purely kinetic deduction of the velocity q-distribution function, the Boltzmann H-teorem is generalized for including the possibility of nonextensive out of equilibrium effects. Based on this investigation, it is proved that Tsallis' distribution is the necessary and sufficient condition defining a thermodynamic equilibrium state in the nonextensive context. This result follows naturally from the generalized transport equation and also from the extended H-theorem. Two physical applications of the nonextensive effects have been considered. Closed analytic expressions were obtained for the Doppler broadening of spectral lines from an excited gas, as well as, for the dispersion relations describing the eletrostatic oscillations in a diluted electronic plasma. In the later case, a comparison with the experimental results strongly suggests a Tsallis distribution with the q parameter smaller than unity. A complementary study is related to the thermodynamic behavior of a relativistic imperfect simple fluid. Using nonequilibrium thermodynamics, we show how the basic primary variables, namely: the energy momentum tensor, the particle and entropy fluxes depend on the several dissipative processes present in the fluid. The temperature variation law for this moving imperfect fluid is also obtained, and the Eckart and Landau-Lifshitz formulations are recovered as particular cases

Adsorção de Mn (II) e Zn (II) em soluções aquosas usando perlita expandida revestida com quitosana

In this work, chitosan was used as a coating of pure perlite in order to increase the accessibility of the groups OH- e NH2+the adsorptionof ions Mn2+ e Zn2+.The characterization results of the expanded perlite classified as microporous and whose surface area 3,176 m2 g-1after the change resulted in 4,664 m2g-1.From the thermogravimetry(TG) it was found that the percentage of coating was34,3%.The infrared analysis can prove the presence of groups Si-OH, Si-O e Al-O-Siresulting from the perlite and C=O, NH2and OH characterization of chitosan. The experiments on experiments on the adsorption of Mn and Zn were performed in the concentration range of10 a 50 mgL-1and the adsorption capacity inpH 5,8 e 5,2 was 19,49 and 23,09 mgg-1to 25 oC,respectively.The adsorption data were best fitted to Langmuir adsorption model to Langmuir adsorption model for both metalionsisindicative of monolayer adsorption. The kinetics of adsorption were calculated from the equation of Lagergren fitting the model pseudo-second-order for all initial concentrations, suggesting that adsorption of ions Mn2+ and Zn2+ follows the kinetics of pseudo-second-order and whose constant Speedk2(g/mg.min) are 0,105 e 3,98 and capacity and maximum removal qe 4,326 e 3,348,respectively.In this study we used a square wave voltammetry cathodic stripping voltammetry to quantify the adsorbed ions, and the working electrode glassy carbon, reference electrode silver / silver chloride and a platinum auxiliary electrode. The attainment of the peaks corresponding to ions Mn2+ and Zn2+ was evaluated in and electrochemical cell with a capacity of 30 mL using a buffer system (Na2HPO4/NaH2PO4)at pH 4 and was adjusted with solutionsH3PO4 0,1molL-1and NaOH 0,1 molL-1and addition of the analyte has been a cathodic peak in- 0,873 Vand detection limit of2,55x10-6molL-1para Zn.The dough used for obtaining the adsorption isotherm was 150 mg and reached in 120 min time of equilibrium for both metal ions.The maximum adsorption for 120 min with Mn concentration 20 mgL-1 and Zn 10 mgL-1,was91, 09 e 94, 34%, respectively

As Mulheres e as Muralhas do Patriarcado e do Capitalismo: Terceirização e Precarização do Trabalho no Sistema do Capital

Our dissertation deals with the material living conditions of women workers and the relations of the wage who undergo in the hospital scope, taking as the locus of empirical research the Hospital Dr. João Machado, located in Natal / RN. Its purpose is to analyze the main implications of precarious work contracts in the economic and social dimensions from life of workers, explaining the main conditionings. The majority presence of women in wage relations not only in the hospital service, as well as in the service sector in general has motivated us to appreciation of the form of participation of women in health services and, in particular, at the hospital space. From the critical dialectical method, through processes of successive approximations to the reality, we analyze the patriarchal system of social relations and their repercussions for the Social and Sexual Division of Labor in the context of contemporary capitalist society, explaining the determinants of inequality, founded in social relations of sex, to the predominance of women in the hospital service and unveiling these participation trends in the labor market. The analyzes are based on bibliographic research - theoretical and methodological basis of research - combined with reflections that emerged from the field. The systematized and analyzed information reveal the uniqueness of the current social and economic situation of workers women with ties outsourced, paradoxically expresses on the expansion of the insertion in universe of labor, in overexploitation, in the precariousness of work and living conditions and persistent inequality in and in the social relations and in relations between the sexes
