Luta pela terra, luta pela palavra: história de vida e formação de duas educadoras populares do campo

This project has resulted from a reunion between me and two teachers with whom I had already worked, pedagogically counseling them during the execution of the Project of Youngsters and Adults Schooling at the Agrarian Reform Settlements in the State of Sergipe (PAJA/PRONERA) between 2002 and 2003. The matter that really motivated the research was related to the essential principle that guided the accomplishment of the PAJA s teachers education and professionalization: understanding their reality and knowing their needs, promoting the dialogue between scientific and common sense knowledge. Taking as a reference the fact that the teachers education is not restricted to the academic qualification, that is, that it is a part of the educational process, which, in turn, is a result of each one s personal background, dialectically individual and collective, the access to the teachers reality and needs was accomplished by studying their backgrounds, especially their school and professional career. They, inevitably, focused themselves on the country life s social and cultural context, that could be better understood by living together with the teachers during the twenty-seven days I stayed in the Golfo s settlement, located in the town named Pacatuba/SE. The approach to the teachers lives through their stories and the daily contact proved how much Science is still distant from the peasants routine, sometimes being presented to them as a finished product . That way, the dialog between those two categories and the expectation of the country life s social and cultural conditions, together with the education, in which teachers have an essential role, still remain as a challenge

Campo educacional e representação social da formação docente :o olhar dos agentes

Teaching formation has been the target of many changes, having been forged according to numerous formats and models through different times and spaces, composing thus, different codes and curricular proposals for different levels of qualification. We've tried in this work to pinpoint the main discussions which take place in the area of the teaching formation, based in the views of modern writers. We ve also tried, through the Social Representations Theory, to reveal and learn how the agents directly involved in this process realize and react, that is, the teachers who cope with the beginning stages of the Fundamental Teaching in the public school system in Natal/RN, taking into account that, in many cases, such formation demands the rethinking of the very formation policies. We've also adopted the concepts of field and educational field introduced by the praxiology of Pierre Bourdieu. It s been considered a fundamental theoretical reference which enables the understanding of social phenomena, both in macro and micro viewpoints. Thus, we do not neglect the whole, and particularly, the nuances of each context or specific situation. In the methodological track we ve used for data gathering the Free Word Association Test, and the Semi-Structured Interview, and also secondary sources for the characterization of the research spectre. Data treatment and analysis were performed with the help of the following software: SPSS Statistical Package for Social Sciences and EVOC; and the method of Content Category Analysis. The combination of the concepts and techniques mentioned above was necessary to cope with the qualitative and quantitative aspects, in our attempt to offer a wider range of contributions and outcome validations, which have shown, among other less explicit elements, the existence of a social representation of the teaching formation such as: knowledge theoretical and practical; a necessity imposed by the symbolical conflicts of the social field; capacitation and compromisse. We acknowledge the relevance of the thoughts discussed here, though aware that this is just one of the possible approaches to the theme

Educação do campo e alternância :reflexões sobre uma experiência na Transamazônica/Pará

The study theme is the Rural Familiar House Program (RFHP), through the Rural Familiar House of Uruará-PA city (URFH), from 2000 to 2005. It is considered as base the education offered to the field young people, in the modality of basic education by alternation methodology between the Familiar and School Times in the two first from 5th to 8th grade classrooms. From the argument about the understanding importance and need of knowledge transmission and construction to be established in the inter-section between general references of the social reality and the subjective ones. It constitutes an educative work that both values domain of knowing and the creative capacity of each pupil. Considering that the greatest aim of the education is the human being emancipation, this thematic for the development of the documentary and field research was defined with the delimitated thematic for the educative practice-proposal in alternation, choosing the Program of the RFHs as the reference to carry out an analysis which considered fruitful in the articulation between education and educative work. This study had the objective to contribute for the debate concerning the alternation and to understand presuposals and educative practice of the RFHs what its importance for the young people and its relation with the field educational policy. For this, it was used, mainly, from analytical references of authors, such as Williams, Gramsci, Adorno, Freire, Shiva, Soares, Molina, Tonet, et. all, all were also important for the construction of this work. The studied documentary sources, as well as the verbal ones the actors also interviewed had allowed, in irreplaceable way and significantly, a critical analysis on the pedagogical proposals and the articulation among school, familiar work and education, which was carried out in the formation of URFH, the sessions of alternation between Time School and Time Family. The results are scored with the chapter construction, as they had presented themselves in several sources and the reading which was made. A reading that signals for the affirmation which is possible to overtake the emphasis on technicality, mediated in the practice-theory-practice relation, still present in the alternation, and, thus, to be able to make an educative work that intends to contribute for the young people education with capacity of being, thinking and to act actually as subjects of their history

Trânsito de saberes e campo representacional na visão dos profissionais da saúde da família e do programa de educação pelo trabalho e para a saúde

The Family Health Strategy (ESF) is emerging as a possible restructuring of services and new practices of intervention in health care; it requires skilled professionals to work with that framework. Within this purpose, we established the Education Programme for Work and Health (PET-Saúde), in order to integrate teaching and service activities, focusing on primary care. On this basis, the aim of this work is to apprehend the social representation of nurse, doctor and dentist (Project PET-Natal Health RN preceptors) on the ESF, while practice field of them. It is a descriptive and exploratory study, with a qualitative approach, carried out in 07 Family Health Units (USF) included in the PET-Saúde Natal (RN). The population was composed of 35 professional components of the primary care team with bachelor's degree of the USF linked to this project. The sample was composed of 05 nurses, 05 physicians and 05 dentists, for a total of 15 subjects. Data were collected through three instruments: the drawing-themed story, a semi-structured individual interviews and field diary. The data relating to the identification of the subjects were entered and tabulated by the Microsoft Excel software 2007 version. The drawing analysis and interpretation is given by the significance attributed to the resource chart from title and keywords assigned by the subjects, considering the ESF as an inductive term. The stories and interviews were transcribed and typed and then subjected to read/listen the material and a lexical analysis through Alceste. After this process, the discursive material was analyzed and discussed by theoretical and methodological feature of the Social Representations theory. The majority of health professionals were female, aged between 46 and 52 years old, married, income less than six minimum wage, time since graduation ranged from 22 to 29 years and working time in the ESF range from 02 to 11 years. From the classification system ALCESTE were selected categories identified by: Category 1 - ESF: relations and territory; Category 2 - Training and bond profile; Category 3 - Working process in the ESF; Category 4 - Articulation between teaching and service; Category 5 - Health care and disease prevention. The representational field construction, while a process, followed the logic of structural cores in existing categories. In this sense, it is clear that the ESF is an environment rich in diversity, experience and relationships with potential such as the relationship "very subject-subject" and the link established between professional-community, but also has some weaknesses such as poor working conditions, lack of popular participation and management support, thus difficulties in the achievement of teamwork. Being essential to that end, the teaching-service aimed at the formation of a new health professional able to work in the ESF. In this research, the training of the representational field encountered a diversity of structural cores, or thoughts on training, about the ESF because of the greater emphasis on the here and now of the interaction between health professionals, the ESF, the community, PET Health-UFRN and students, emphasizing that such proposals are still considered as concepts in the context of recent health and that, therefore, are not fully realized in the social imaginary

Predicao de campo em comunicacao sem fio

Even living in the XXI century are still some difficulties in access to broadband Internet in several Brazilian cities, due to the purchasing power of people and lack of government investment. But even with these difficulties, we seek to encourage the use of wireless technology, which is based on the IEEE 802.11b protocol - also known as Wi-Fi (Wireless Fidelity) Wireless Fidelity Communications, having wide range of commercial applications in the world market, nationally and internationally. In Brazil, this technology is in full operation in major cities and has proved attractive in relation to the access point to multipoint and point-to-point. This paper is a comparative analysis of prediction field, using models based on the prediction of propagation loss. To validate the techniques used here, the Okumura-Hata models, modified Okumura-Hata, Walfisch-Ikegami model, were applied to a wireless computer network, located in the neighborhood of Cajupiranga in the city of Melbourn, in Rio Grande do Norte . They are used for networking wireless 802.11b, using the Mobile Radio to measure signal levels, beyond the heights of the antennas and distances from the transmitter. The performance data versus distance are added to the graphs generated and compared with results obtained through calculations of propagation models

Mapeamento geoambiental do campo de dunas Pirangi-Potengi com ênfase a San Vale e Lagoinha Natal/RN: um instrumento de apoio ao planejamento ambiental

The city of Natal-RN is constructed on dune areas with wavy relives softly waved and green areas that help to keep a pleasant climate, amongst these is distinguished field Pirangi-Potengi the dune with the areas of San Vale and Lagoinha. These environments are being substituted gradual for property and other workmanships of engineering on behalf of the urban expansion. This study the elaboration of a geoambiental mapping of Field had as objective generality Pirangi-Potengi the Dune with emphasis the San Vale and Lagoinha in Natal-RN. The done mapping had as objective specific to elaborate a vegetation map, a map of registers in cadastre of ambient problems to dunes, a map of flooding susceptibility, a map of vulnerability to the underground water contamination and a map of use and occupation of the ground. Of the carried through analysis, the area in study reveals sufficiently degraded, remaining only few green areas and dunares, as well as, the vulnerable presence of areas of vulnerability in floods and areas the contamination of the water-bearing one. The gotten results allow to affirm that this type of mapping, is of great importance for analysis and evaluation of the environment of the city

Diagnóstco geoambiental e avaliação de uso e ocupação do campo de dunas da zona especial de interesse turístco II (ZET-II) Natal/RN

The accelerated pressure of use and occupation of Rio Grande do Norte coastline in the last two decades presented the tourism as its main vector, having as a consequence a strong, articulated and growing real estate speculation of this area. In the Natal County there is a Zona Especial de Interesse Turistico II (Special Zone of Tourism Interest II) (ZET-II), consisted of urban beaches with approximately 8.5 km that is an important seashore of the city. The purpose of this research was identification, characterization and assessment of the process of use and occupation of dunes fields emphasizing the role of ZET-II, whereas the specific goals was the analysis of weather, geology and geomorphology, characterization of use and occupation of soil, and elaboration of an environmental diagnosis with identification and description of its mains consequences. The result of this work was the delineation of geologic-geomorphological map of the area with identification of principals units, determining its use and occupation, the measurement of the area already occupied by equipments, besides the description of the environmental impacts on dune fields: devastation, coastline erosion, ocean pollution by sewer and pluvial waters, contamination of groundwater, distribution inadequate of solid residues, landscape degradation, and occupation of seashore through the privatization of public areas. Concluding that the degrading changes occurred in this areas are resulting from the nature of use and urban seashore regulations, which have been diminishing the natural aspect, altering the landscape definitely, compromising the quality of hydro resources and altering its use, privatizing the areas between tides, complicating the population access and obstructing the scenery visualization of dunes and ocean. There is an urgent necessity of improvement of public politics in order to improve the strategies and organization of use and occupation of space urban-coastline

A esfera como metáfora: representações do futebol no campo da literatura (leituras do tema no conto de ficção)

Football, understood as a phenomenon of sports practice and nearly universal coverage, can also be seen as a game whose operation circumvents the cultural universe of people who practice it. Much more than just a sport, so this game is a cultural phenomenon par excellence, bearing a communicational and aesthetic dimension whose occurrence has been spotted in various fields of scientific and cultural. Therefore, it is as game and as a phenomenon of culture, we intend to focus on football here as an object of study. Our aim is to investigate the sport in Brazil taking the Literature and Journalism as privileged instances of their representation in the media. Thus, the central idea of this research is to show when and how football has become a recurrent theme in Brazilian literature, starting with its journalistic approach until we get an overview of the aesthetic representation of the game, Literature as the main focus of attention and taking the genre of fiction story as material fact of their representation. With this approach, we intend to develop an overall view, overview of the literature about football in our country and at the same time, particularize this vision in some representative authors of it, like the writer-journalist Mario Filho (the historian, essayist on the modernization of chronic specific theme), José Lins do Rego (writer passionate about the game), Nelson Rodrigues (the esthetician that elevated the sport to the status of art by chronic), Lima Barreto (who along with Antonio de Alcantara Machado pioneered the formalized within the fiction) and the storytellers of the topic itself. In the end, we intend to infer the results of evaluations and reviews of books and authors listed, we have examined a wide sense, but also vertical (and which were focused on a socio-historical perspective and critical-aesthetic) within the assumption that seems be a homology between the way football practice amongst us will historically winning characteristics as to form a Brazilian school of football, and how our writers, journalists will be addressing the topic, which also would focus on creating a "Brazilian way" of telling literary football. The proof of this hypothesis operational work together with the development of historiography and the necessity arising from it, creating a "Guide to Reading football theme in fictional tale of Brazil" shut the focal perspective of this study

O Psicólogo no campo do Bem-Estar: cartografias de práticas na saúde e assistência social

The study focuses on the psychology and Social Well-being Policy encounters. The objective is to understand how the psychologists in the health services of Natal, RN, specifically in the Basic Health Units and social assistance, experience their daily practices. The methodology included observation and interviews of 13 psychologists regarding their daily activities and forms of practice in these services. We utilized an interview protocol directed at the affective memory and the professional life history of these technicians. Field notes were used to produce a cartography of the encounter intensities experienced by the researcher in the investigated context. The data analysis enabled the construction of the following analytic axes: 1) Work processes and proximity/ distancing points between these fields; 2) Forms of government and life management in the well-being context; 3) Experiments of self in the daily services. The first axis showed the precariousness of working conditions (remuneration issues, lack of structure, of training and autonomy for the activities). In the second axis the identified care forms produced in these fields indicated an adherence to the production of ideal subjects characterized as autonomous, productive, healthy and aware of own rights . These were considered normative insofar as they express attempts to break with the established patterns. In the third axis, many technicians experienced constraint with the daily activities because they found themselves in contexts that were adverse to the habitual forms of action. This situation provoked two distinct forms of positioning: a) action expressed by compassion, pity and resentment; b) investment in the practices themselves, so as to overcome its limits and to respond innovatively to the difficulties and/or challenges that these contexts provoke

Inserção e atuação profissional do psicólogo no campo das políticas sociais no Rio Grande do Norte

Since the first years of the regulation of Psychology as a profession in Brazil, it has been carried out studies on the academic graduation, practice, workplace and the social commitment of the category. Despite the diversity of goals and propositions, these studies show that psychologists have been significantly inserted into the social policies field, implying changes in the profession. Since the 1980s, researches in Rio Grande do Norte corroborate the results of national studies. The aim of this paper is to study the insertion and professional career of psychologists in the social policies field in Rio Grande do Norte. In order to accomplish the final results of this paper, it was developed an exploratory research, with the use of a questionnaire, comprised of four parts: general data, academic graduation, complementary graduation and professional experience. The results show three groups of information: characterization, insertion and professional performance. It has been verified expressive insertion of psychologists into the social policies field (41%). The socio-demographic and graduation characteristics are not different from those shown by literature: women, young, from families with an average of 7 to 15 minimum wages. Most of them graduated from public institutions and with post-graduation studies in clinical area. The professionals studied seem to be in worse working conditions compared to the rest of the category, which are also in unfavorable conditions, especially the psychologists who work in social assistance institutions, which present greater problems in its structure. The activities developed do not show anything new, reserving conservative practices instead of effective innovations, emphasizing the discussion on the profession for not considering demands presented to the psychologists in the social policies field. With unique scenario, the eproduction of liberal values corroborates classic performance standards; an unpolitical and uncritical practice is diffused. It is then reconsidered the importance of critical studies that organize goals to the category, with the aim of political transformation concerning the current scenario.

Desenvolvimento e teste de um modelo estatístico de identificação das proporções de água produzida em zonas de produção de um campo maduro de petróleo

This study investigates the chemical species produced water from the reservoir areas of oil production in the field of Monte Alegre (onshore production) with a proposal of developing a model applied to the identification of the water produced in different zones or groups of zones.Starting from the concentrations of anions and cátions from water produced as input parameters in Linear Discriminate Analysis, it was possible to estimate and compare the model predictions respecting the particularities of their methods in order to ascertain which one would be most appropriate. The methods Resubstitution, Holdout Method and Lachenbruch were used for adjustment and general evaluation of the built models. Of the estimated models for Wells producing water for a single production area, the most suitable method was the "Holdout Method and had a hit rate of 90%. Discriminant functions (CV1, CV2 and CV3) estimated in this model were used to modeling new functions for samples ofartificial mixtures of produced water (producedin our laboratory) and samples of mixtures actualproduced water (water collected inwellsproducingmore thanonezone).The experiment with these mixtures was carried out according to a schedule experimental mixtures simplex type-centroid also was simulated in which the presence of water from steam injectionin these tanks fora part of amostras. Using graphs of two and three dimensions was possible to estimate the proportion of water in the production area

Ecossocialismo: a gênese de uma ecologia social em assentamentos de reforma agrária a partir dos movimentos sociais do campo

The world`s ecology crisis has in the capitalism way of production one of the possible causes. The unstopped search for the profits, into unlimited exploration of limited resources, made a huge transformation in human relationships with the nature, causing environment devastation, shortage of resources and species disappearance. Arises the necessity of question the society model that we are and which brings this crisis state, while we are impelled to search an alternative way. The ecosociallist praxis blows marxist principles with ecological matters, bringing important contributions regarding alternatives to capital/exploratory modus, advocating for a social fair society and environmentally sustainable. This way, by bibliographic review, we will research about this theory which have been growing in academic middles. In the same way, we will analyze the rural social movements paper in the construct of this reality. Throut the half estruture interviwes, bibliografic research and visities in the space of settlement called Moacir Lucena, that is today a exemple of rural resignification

Evolução tectono-estrutural do Campo de Xaréu (Sub-bacia de Mundaú, Bacia do Ceará - NE do Brasil: abordagem multiescala e pluriferramental

The Xaréu Oil Field, located in the center-southern portion of the Mundaú Sub-Basin (eastern portion of the Ceará Basin), is characterized by a main Iramework of NW-trending and NE-dipping faults. The faults in the Xaréu Oil Field, among which the Xaréu Fautt stands out, are arranged according to an extensional-listriclan, rooted on a detachment surface corresponding to the Mundaú Fault, the border fautt of Mundaú Sub-Basin. During the tectonic-structural evolution of the Xaréu Oil Field and the Mundaú Sub-Basin, the Mundaú Fault played a crucial role on the control of the geometry of both compartments. The main carbonatic unit in the Xaréu Oil Field, named the Trairí Member(Paracuru Formation of Late Aptian to Early Albian age), contains the largest oil volume in the field, concentrated in structurally-controlled accumulations. The Trairí Member is composed by a variety of carbonatic rocks (massive, bedded or laminated calcilutites, ostracodites, calcarenites and carbonatic rudites, all of them presenting variable degrees of dolomitization). The carbonatic rocks are interbedded into thick packages of black shales and marls, besides local beds of siliciclastic conglomerates, sandstones, siltnes and argillites. From the spatial association and the genetic relationships between the carbonatic and siliciclastic units, it is possible to group them in three lithofacies associations (Marginal Plain, Ramp and Lacustrine Interior) that, together, were developed in a lacustrine system associated to a marginal sabkha. Structural studies based on drill coresthat sample the Trairí Member in the Xaréu Oil Field allowed to characterize two generations of meso- to microscale structures: the D1 group presents a typical hydroplastic character, being characterized by intra/interstratal to oblique-bedding shear zones. The hydroplastic character related to these structures allowed to infer their development at an early-lithilication stage of the Trairí Member, leading to infer an Early Cretaceous age to them. The second group of structures identified in the drill cores, nominated D2 and ascribed to a Neogene age, presents a strictly brttle character, being typilied by normal faults and slickenfibers of re-crystallized clayminerals, ali olthem displaying variable orientations. Although the present faults in the Xaréu Oil Field (and, consequently, in the Mundaú Sub-Basin) were classically relerred as struetures of essentially normal displacement, the kinematics analysis of the meso-to microscaie D1 struetures in the drill cores led to deline oblique displacements (normal with a clockwise strike-slip component) to these faults, indicating a main tectonic transport to ENE. These oblique movements would be responsible for the installation of a transtensive context in the Mundaú Sub-Basin, as part of the transcurrent to translormant opening of the Atlantic Equatorial Margin. The balancing of four struetural cross-sections ofthe Xaréu Oil Field indicates that the Mundaú Fault was responsible for more than 50% of the total stretching (ß factor) registered during the Early Aptian. At the initial stages of the "rifting", during Early Aptianuntil the Holocene, the Mundaú Sub-Basin (and consequently the Xaréu Oil Fleld) accumulated a total stretching between 1.21 and 1.23; in other words, the crust in this segment of the Atlantic Equatorial Margin was subjeeted to an elongation of about 20%. From estimates of oblique displacements related to the faults, it ws possible to construct diagrams that allow the determination of stretching factors related to these displacements. Using these diagrams and assuming the sense 01 dominant teetonictransport towards ENE, it was possible to calculate the real stretching lactors related to the oblique movement 0 of the faults in the Mundaú Sub-Basin. which reached actual values between 1.28 and 1.42. ln addnion to the tectonic-structural studies in the Xaréu Oil Field, the interpretation of remote sensing products, coupled wnh characterization of terrain analogues in seleeted areas along the northern Ceará State (continental margins of the Ceará and Potiguar basins), provided addnional data and constraints about the teetonic-structural evolution of the oil lield. The work at the analogue sites was particularly effective in the recognition and mapping, in semidetail scale, several generations of struetures originated under a brittle regime. Ali the obtained information (from the Xaréu Oil Field, the remote sensor data and the terrain analogues) were jointly interpreted, culminating with the proposnion of an evolutionary model lor this segment of the Atlantic Equatorial Margin; this model that can be applied to the whole Margin, as well. This segmentof the Atlantic Equatorial Margin was delormedin an early E-W (when considered lhe present-day position of the South American Plate) transcurrent to transform regime with dextral kinematics, started Irom, at least, the Early Aptian, which left its record in several outcrops along the continental margin of the Ceará State and specilically in the Xaréu off Field. The continuous operation of the regime, through the Albian and later periods, led to the definitive separation between the South American and African plates, with the formation of oceanic lithosphere between the two continental blocks, due to the emplacement off spreading centers. This process involved the subsequent transition of the transcurrent to a translorm dextral regime, creating lhe Equatorial Atlantic Oceano With the separation between the South American and African plates already completed and the increasing separation between lhe continental masses, other tecton ic mechanisms began to act during the Cenozoic (even though the Cretaceous tectonic regime lasted until the Neogene), like an E-W compressive stress líeld (related to the spreading olthe oceanic floor along lhe M id-Atlantic Ridge and to the compression of the Andean Chain) effective Irom the Late Cretaceous, and a state of general extension olthe horizontal surface (due to the thermal uplift ofthe central portion of Borborema Province), effective during the Neogene. The overlap of these mechanisms during the Cenozoic led to the imprint of a complex tectonic framework, which apparently influenced the migration and entrapment 01 hydrocarbon in the Ceará Basin
