Sujeitos e atores sociais nas representações discursivas de docentes da rede estadual de ensino em Sergipe: uma análise crítica em tempos de Ideb

According to the studies in Applied Linguistics, this thesis is based on an interdisciplinary perspective (Critical Discourse Analysis, Sociology towards Social Change, Cultural Studies and Systemic-Functional Linguistics). The overall objective of the research was to analyze the discourses of Elementary School teachers in the state of Sergipe, by means of the discursive representations of the social actors, the processes of subjectivity and their fragmented identities in the context of standardized evaluations before the requirements of globalized pedagogical practices, based on the result-based management. The critical analysis of such discourses was motivated by the rapid pace with which the demands of innovation become part of the classroom, aiming at reaching the target in what concerns the indexes of the rankings which characterize the globalized discourse of the national education management, like Ideb (Basic Education Development Index), which makes teachers change their discourses, become silent or keep resistant. The work was initially endorsed by the theoretical lines of the Critical Discourse Analysis (FAIRCLOUGH, 2001, 2006), and poses a proposal for such purpose: the ASCD Discourse Sociological and Communicative Approach (PEDROSA, 2012, 2013). This is an interpretative-qualitative study of the Critical Discourse Analysis (FAIRCLOUGH, 2001, 2003; RAMALHO ; RESENDE, 2011) and to carry it out, semi-structured interviews were used as instruments of data generation (BAUER; GASKELL, 2011; GILL, 2011). Its corpus is composed of thirteen accounts of teachers from the Elementary school who teach Portuguese and work in the fifteen schools which were chosen to be the universe of the research at the Regional Board of Education (02) in the state of Sergipe. Such narratives are related to their impressions, expectations and actions which favor the management of results to which they have to submit themselves. The analytical overview of sociological and discursive line comes from the pan-semiotic categories (Inclusion and Exclusion) which appear in the theory of Representation of Social Actors (VAN LEEUWEN, 1997, 2008). To present the processes of subjectivity of these teachers, this work is based on the socio-analytical proposal of the classification of the subjects, which stems from the individual s work in the Gestão Relacional de Si , which comes from the Applied Sociology (towards) Social Change (BAJOIT, 2006, 2009). The discursive analyses were guided word for word, in their majority, by having the Systemic Functional Grammar as their theoretical basis, specifically by the processes of the Transitivity System postulated by Halliday, (1985); Halliday and Mathiessen, (2004); Eggins (2004); Cunha and Souza (2011). The work makes the field of Cultural Studies emerge towards the dialogue and the presentation of the fragmented identities of the teachers in the context of late modernity (GIDDENS, 2002; HALL, 2011). The thesis promoted a reflection over the teacher s condition, who is immerse in this context of knowledge construction of the present Brazilian educational system, the standardized evaluations, the indexes of development, the targets and the rankings. The considerations and outcomes of such a research dealt with the teachers emerging social practices and the need of planned initial and continuing teacher education towards the new moment which is foreseeable

A criança e o brinquedo-TV: análise sobre o discurso publicitário direcionado para a infância na Rede Globo de Televisão

Esta investigación es un análisis del contexto actual que rodea a la publicidad brasileña, más concretamente, la publicidad discurso televisivo dirigido a los niños en Brasil. Análisis de los documentos se basa en la revisión retórica (Leach, 2004) (SODRE, 2006) A partir de la primera supuesta inadecuación de algunos de sus contenidos al público para que se comunican. También investiga las posibilidades de regulación y la educación del consumidor y el papel de los medios de comunicación en la sociedad mediante la movilización exigiendo el cumplimiento y la mejora de la legislación vigente, evitando los posibles abusos y distorsiones de las secciones generales de la ley. Hemos llevado a cabo por separado se analiza en los niños y sus conceptualizaciones y la función social, abordando también el juguete y el acto de jugar hoy y su sede histórica en un intento de crear una fundación que apoya el análisis de la relación entre la infancia y la publicidad y el consumo, basado en obras de Roger Silverstone, Kapferer, Leontiev y Walter Benjamin. También se hicieron inferencias basadas en estudios de Pablo Del Río, sobre las posibles consecuencias psicológicas del consumo de medios por los niños, sin embargo, en arvorarmos llevar a cabo investigaciones en el estudio de la recepción. Se enfrentarán, tanto en acciones a favor de la aprobación de la Ley 5.921/2001 N º Suplente sugiere que la prohibición de la publicidad infantil en todo el país, los enfoques ampliamente "integrado" y por lo tanto, favorables a la continuidad de la actividad publicitaria en el país bajo la acción de la CONAR de autorregulación, lo que demuestra sin embargo, la viabilidad de ambas propuestas. Tambien relativa a el CONAR se llevó a cabo un estudio sobre su Consejo Asesor, dando a entender su composición y características. Por último, se estudian las posibilidades y el concepto de la educación para el consumo de los medios de comunicación, a partir de la utilización de los recursos de los propios medios de comunicación, como una propuesta para un cambio de paradigma en el mercado de la publicidad en Brasil. En conclusión, vemos que a partir del análisis de la publicidad comercial de los niños atendidos por la Red Globo de Televisión, en una muestra de 170 inserciones, todavía existen graves lagunas, pero que los desequilibrios se pueden resolver con medidas relativamente sencillas que incluyan campañas de educación y la exigencia de adecuación de los pocos grandes anunciantes que violan la ley. Afortunadamente, una nueva entrega de los anunciantes mostró la responsabilidad social en sus acciones

Estratégias midiáticas na aprendizagem do tema DST/AIDS: ações em rede para reduzir vulnerabilidades de adolescentes e jovens da comunidade de Mãe Luiza, Natal-RN

Youngsters and teenagers are still a very vulnerable group of DST/AIDS. In order to combat this vulnerability the community intervention project being developed in Mãe Luiza neighborhood in the city of Natal-RN, entitled Strengthening Community Action Network for Prevention in HIV/AIDS: knowledge and Intervene emerged, popularly known as Project Viva Mãe Luiza. The project develops workshops of educomunication whose approach involves the DST/AIDS subject with the following media: video, photography, and theater playbook. This research integrates the activities of the project and has as main objective to investigate how strategies and practices of media communication developed in Project Viva Mãe Luiza through workshops of educomunication, assisted learning for the prevention of DST/AIDS and contributed to the reduction of vulnerability to DST/AIDS among adolescents and young participants of the project residents of Mãe Luiza community. The methodological basis was based on intervention research, with the technique of gathering daily field data, literature and documentary, in-depth interviews and ethnographic observation. The qualitative analysis was based on the monitoring of video workshops, photography, theater and primer, respectively, crossed by transverse to the prevention of DST/AIDS, conducted between June 2012 and December 2013 issues. Interviews with eight multipliers, aiming to understand their perceptions of vulnerability, prevention, multiplication and use of media that were part of the project were conducted. The analyzes show that learning workshops educomunication community health repercussions both in the development of individual skills in communication as changing perceptions about the vulnerabilities to which they are exposed, the awareness about prevention at the individual and differentiated actions multiplication in the community

Modelo de ashkin-teller de três cores na rede ponte de wheatstone

In this work we study the phase transitions of the ferromagnetic three-color Ashkin-Teller Model in the hierarquical lattice generated by the Wheatstone bridge using real space renormalization group approach. With such technique we obtain the phase diagram and its critical points with respective critical exponents v. This model presents four phases: ferromagnetic, paramagnetic and two intermediates. Nine critical points were found, three of which are of Ising model type, three are of four states Potts model type, one is of eight states Potts model type and the last two which do not correspond to any Potts model with integer number of states. iv

Fraturas e caminhos ótimos na rede de Barabasi-Albert

Following the study of Andrade et al. (2009) on regular square lattices, here we investigate the problem of optimal path cracks (OPC) in Complex Networks. In this problem we associate to each site a determined energy. The optimum path is defined as the one among all possible paths that crosses the system which has the minimum cost, namely the sum of the energies along the path. Once the optimum path is determined, at each step, one blocks its site with highest energy, and then a new optimal path is calculated. This procedure is repeated until there is a set of blocked sites forming a macroscopic fracture which connects the opposite sides of the system. The method is applied to a lattice of size L and the density of removed sites is computed. As observed in the work by Andrade et al. (2009), the fractured system studied here also presents different behaviors depending on the level of disorder, namely weak, moderated and strong disorder intensities. In the regime of weak and moderated disorder, while the density of removed sites in the system does not depend of the size L in the case of regular lattices, in the regime of high disorder the density becomes substantially dependent on L. We did the same type of study for Complex Networks. In this case, each new site is connected with m previous ones. As in the previous work, we observe that the density of removed sites presents a similar behavior. Moreover, a new result is obtained, i.e., we analyze the dependency of the disorder with the attachment parameter m

Pecolação em uma rede multifractal

In this work we present the principal fractals, their caracteristics, properties abd their classification, comparing them to Euclidean Geometry Elements. We show the importance of the Fractal Geometry in the analysis of several elements of our society. We emphasize the importance of an appropriate definition of dimension to these objects, because the definition we presently know doesn t see a satisfactory one. As an instrument to obtain these dimentions we present the Method to count boxes, of Hausdorff- Besicovich and the Scale Method. We also study the Percolation Process in the square lattice, comparing it to percolation in the multifractal subject Qmf, where we observe som differences between these two process. We analize the histogram grafic of the percolating lattices versus the site occupation probability p, and other numerical simulations. And finaly, we show that we can estimate the fractal dimension of the percolation cluster and that the percolatin in a multifractal suport is in the same universality class as standard percolation. We observe that the area of the blocks of Qmf is variable, pc is a function of p which is related to the anisotropy of Qmf

Atividades educativas na rede pública de ensino: efeitos sobre a higiene oral e o nível de informação em Saúde Bucal

The contents introduction concerning the individual health cares reveals important since the school education. In this direction, the present study objectified to know an effect of Oral Health education intervention in the oral hygiene and in the schools children information level, of 4º e 5º basic education years. The study was composed by two groups, chosen of random form: control group (n = 115) and experimental group (n = 132), with 247 public net school children in total sample. The experimental group participated of some educative activities in Oral Health, with biweekly frequency, during the 4 months period, given for a surgeon-dentistry. Both the groups were submitted to a clinical examination for a previous verification of the Plaque Index (PI) and of Loe Silness Gingival Index (GI). A questionnaire with closed questions on Oral Health was applied before and after to verify the school children rightness index. After the intervention, the final data, represented for the PI, GI and Rightness Index verification, has been collected for statistical analyses through the chi-square test to a 95 % of reliable level, using the SPSS 10,0 software. The PI and GI were categorized in high and low on the initials index basis medium; already the Rightness Index was categorized in inadequate (< 50%) and adequate (≥ 50%). It was verified that the PI (p = 0,014; IC 0.24-0.86) and the GI (p = 0,013; IC 0,28-0,84) presented differences statistically significant, after the education activities, when compared to with the control, favoring the experimental group. It was verified too the experimental group got greater rightness index, presenting difference highly significant (p<0,0001; IC 3,73-26,81). It was still observed that there was no association between the oral hygiene indicators and the school children information level. Ahead the results, it can been concluded that education activities related in the school routine were capable to give positives effects in the oral hygiene control and in the information level about Oral Health, however, not necessarily, the individual with bigger information is that one who has practiced an oral hygiene more adjusted. One become necessary, however, that the education in Oral Health occurs of permanent and integrated form with others school actors, for the positive effect does not lose the student s life longterm

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

A cooperação em crianças de rede pública de Natal/RN:uma abordagem evolucionista

Cooperation is a well known behavior and influenced by all cultures. Probably selective pressures brought advantages to individuals that cooperate, and then this behavior is current in human societies. Most of it is studied about cooperation and natural selection was understood by the game theory, a mathematical approach that helps to understand the conflict and cooperation. We believe that natural selection and game theory could facilitate understanding these behaviors and two theoretical articles were written regarding this view. It was also found that most of data about cooperation was obtained in (with) adults. Since game theory is effective to understand this phenomenon, and to be used and understood, two games were used with five and eleven year old children: the common pool and public goods games. The results are presented in four empirical articles. We found that children respond to social dilemmas of game theory like the adults do. They adjust their rounds regarding the feedback obtained of their partness; in the beginning they cooperate and reduce the degree of cooperation along (throughout) the following session; in the absence of punition the level of opportunism increased, mainly in larger groups; boys and girls behave differently when donate. This research suggest that cooperation has an evolutionary basis in human and it is since earlier in the behavioral pattern shown by adults.

Nervos: rede de discursos e práticas de cuidado na atenção básica no município de Natal/RN

The Primary Health Care and one of its main strategies, the Family Health Strategy (ESF), are framed as the gateway to the Public Health System (SUS). Thus, most of the incident and prevalent health problems in the population attended should be solved at this level of care, including psychological suffering, and the so-called complaint of nerves. Nerves and nervous denote a complexity that is not always well comprehended by health workers, in such a way that the care to this kind of problem is usually inadequate. In this line of thought, the general objective of this study is to analyze the network of discourses and the care to the psychological suffering, expressed as nerves, in SUS daily Primary Health Care. Besides and more specifically, it aims at identifying the principles and guidelines of the Primary Health Care in mental health; to investigate health workers positioning before psychological suffering and complaints of nerves, and also analyze different actions and practices of care carried out in different Health Units towards complaints like nerves. Institutional Ethnography was the theoreticalmethodological perspective adopted for the work. This approach seeks to understand and analyze the institutional relationships in a particular context considering sociostructural influences and power relations, as well as daily discourses and practices. Based on interviews with health professionals, informal conversations and observations in six Health Units with ESF teams from different sanitary districts in Natal/RN, it was possible to check that the index of complaint of nerves is high. The referral to psychologists and psychiatrists, as well as the prescription of psychotropic drugs appear as the most common intervention at this level of care. In general, the participants complain that they have poor specialized knowledge about the theme of mental health. They face the problem of bad work conditions and the lack of institutional support, which make actions of illnesses prevention and health promotion even more difficult. Besides, there are different ongoing practices such as meetings for hypertensive and aged people, walk, visit, round-table discussions and community therapy. However, not all of these actions are aimed at the care of psychological suffering. It is observed that the Matrix Support, which is a methodological strategy of supervision and follow up forcases of mental health, hasn t been totally implemented in the municipal system, although it is a tool that has been used by psychologists in some Health Units in the city. It was also verified that the health care practices to the problem of nerves strongly depend on the professional s commitment with the PSF guidelines and on mental health policies, in addition to continued support, when available, from other professional who works as matrix supporter

Os profissionais de saúde diante da violência :mapeando o processo de implantaçãoda notificação na rede básica de saúde em Natal/RN

Violence is a complex and multifarious phenomenon that has convoked the government to think about strategies to face the question. This work is about one of these strategies proposed by brazilian Health Minister: the Individual notification/investigation Card - Domestic Violence, Sexual and/or others Interpersonal Violences . This instrument is a notification protocol which is been implanted in all of the country. This process is in course in Natal/RN. This work is a report of one research realized in five units of basic health care network of Natal/RN concerning this process about the implementation of the violence notification card. The study aims to cartography all the process of card implantation, discussing the used strategies, the drawn course, difficulties and possibilities as well as how the researcher intended to map subjective process involved at health professional acting at violence case and the propose to use the card. Meetings were held at each unit and a daily fieldwork report was used as research instrument. In this investigation it was observed that notifying violence involves a complexity that is not present in other kinds of notification as consequence of the phenomenon characteristic and health workers are invited to act in different perspective that knowledge and instruments of traditional health fieldwork available does not work. It was observed that the notification card, as a possible instrument of intervention, are considered important detectors from process of work at health basic care and health policies. Depending the way the instrument is used, it may incentive different discussions and manners to offer health care or in other way it can reproduce control and vigilance logics. Consequently it is necessary to consider some factors pointed out at this experience, implanting instruments like this, thinking about these limits and possibilities
