Mestrado profissional em saúde da família: o curso sob a perspectiva dos mestrandos

Professional masters were created in Brazil in the 1990s in response to social changes in the world of work and aim to train high-level professionals with own profile for various activities of society and the productive sector. They are up in more innovative mode of graduate studies in Brazil, and therefore lack of legitimacy of their identity, which raises the need for discussions to get further information and outline the characteristics of this postgraduate modality. You want to build new understandings about their peculiarities starting from the perspective of students from the Professional Masters in Health Net Northeast Family Training in Family Health, and not only according to the similarities and differences with the academic master. This study aims to understand the meanings attributed by masters training in that course. This is a qualitative, exploratory study. The subjects are 100 students in training in 2013, distributed among the six institutions nucleation Network Northeast Training in Family Health. To collect information desk research was conducted in institutional records of all students, as well as interviews. We interviewed 15 students, distributed in the six nucleation institutions. Information obtained through recorded interviews were transcribed and resulted in two analytical corpus subsequently submitted to Alceste © 4.9 software for identification of semantic classes. It can be concluded that the course provided a redefinition of professional practices in the Family Health Strategy, considering the organizational context of primary care in the Northeast and the specifics of the health work. Even before the student body difficulties related to ownership of research methods, and the very active methodology of problem-based learning, the course effectively contributed to the improvement of work processes in primary care, valuing teamwork and allowing the acquisition of new scientific knowledge.

A geração de 27 e o barroco: la mirada exuberante

From the context of the degree‘s creation of Spanish literature and language‘s course, at UFRN, came the motivation to make this research, that presents a literary study of a poet‘s group known as Generación del 27, that came in to light at Spain, on 1920. A lot of aspects of this study are themes of many others disciplines, of this degree (Spanish Literature II, IberianAmerican Literature, Spanish Culture, Translation in Spanish Language). This work will also serve as inspiration to new reflections and proposes of translations, as bridges between the language that goes and the other that comes. It is the Translation as comprehension‘s negotiation between languages, it is the decir casi lo mismo, here in poem‘s form (ECO, 2007), in the attempt to conclude new learning, that will be shared with undergraduate and graduate students, being at teaching area, extension or new researches. To contextualize this generation‘s studies, were elected the anthologies organized by Gerardo Diego, called Poesía Española (Antologías), published on 2007, by Ediciones Cátedras, and the Antología Comentada de La Generación del 27, wrote by Víctor García de La Concha, published on 2006, by Editorial Espasa Calpe. The research took Generacion Del 27 as their object of research and - from many others critical reading about the poetry made by those young poets, their creative vocation of aesthetics and vanguard – wanted to understand the context of literary‘s creation of those poets del 27. We form our foundation with contributions by Antonio Maravall (2009), Eugenio D‘ors (s.d) Severo Sarduy (1999), Lezama Lima (2011), Alfonso Reyes (1958) e Deleuze (2005) among others that brought the comprehension of the baroque‘s language, giving emphasis to pluridirectional movement, deconstructing it‘s linearity, creating others new forms, as returns, circles, spirals favoring encounters, detachment or equal points of departure and arrivals. In this way, the poets del 27 approached the baroque of six hundred on a re-reading, and made of the third centenary‘s celebration of the Góngora‘s a Mirada exuberante death, to the return of baroque‘s spirit. Alfonso Reyes e Rubén Darío said that real lights highlighted the paths of this poets generation: The light that desdobra scintillates on García Lorca, Jorge Gullén, Dámaso Alonso, Gerardo Diego and the bullfighter Ignacio Sánchez Mejías, poets that expressed tributes in big style to Soledades author, at Madrid‘s Caffe and all Spain.

Ensino da ultrassonografia diagnóstica a partir do ciclo básico do curso de medicina utilizando livro digital multimídia

Currently, the diagnostic ultrasound is inserted in various areas of medical action and carried out by many medical professionals, from which militate directly in the image area, such as radiologists and sonographers, but also by gynecologists, pediatricians, neurologists, general practitioners, endocrinologists, angiologists, orthopedists, rheumatologists, urologists, general and vascular surgeons. It is well known that the medical professional, for the exercise of its mission, requires a broad set of skills, competencies and attitudes developed and exercised during their training period. Living with medical students over nearly 20 years in hospital environment, I noticed gaps in the learning process by the students about what is diagnostic ultrasound and its applications, demonstrating failures as understanding the basic acoustic ultrasound, difficulties in identifying of anatomical structures in ultrasound images and inability in requests examinations and interpretations of images and reports. Based on these findings, it was developed in this Professional Masters a multimedia digital book that exposes what the ultrasound as a diagnostic modality imaging, dealing with its historiography and its physical/acoustic concepts, relating the process of formation of the ultrasound image, discussing about the features of sonographic equipments and their embedded technologies and highlighting its diagnostic applications , the latter presented through videos which will be described aspects of captured ultrasound images. This book will be available for access in digital format, serving as a teaching tool in medical education since the beginning of the course, so that can be used in conjunction with the discipline of Gross Anatomy, offered in the basic cycle of the Medicine Undergraduate Course of the Federal University of Rio Grande do Norte (UFRN).

Desempenho físico em idosos com diferenciados perfis epidemiológicos: análise do estudo IMIAS International Mobility in Aging Study sob a perspectiva do curso da vida e de biomarcadores da inflamação e do estresse

O crescimento demográfico de idosos é um fenômeno mundial e exerce influência sobre o desenvolvimento e funcionamento das sociedades. Fatores sociais, econômicos, ambientais, biológicos e culturais influenciam o processo de envelhecimento, que pode vir acompanhado de contínua perda na capacidade de adaptação do indivíduo ao meio ambiente, de maior vulnerabilidade ao estresse, limitações funcionais e diminuição da qualidade de vida do indivíduo. Todavia, ao longo do curso da vida, o indivíduo vivencia múltiplas exposições adversas à saúde, e o declínio da mobilidade surge como um dos primeiros sinais do envelhecimento, repercutindo na saúde física e mental do indivíduo. Para contribuir com o conhecimento sobre os desfechos relacionados ao envelhecimento e mobilidade, o estudo IMIAS investiga idosos em quatro países com diferentes perfis epidemiológicos. O presente estudo abordou os possíveis fatores associados ao declínio físico em idosos de distintas sociedades, sobre a perspectiva epidemiológica do curso da vida e dos biomarcadores da inflamação e do estresse. Objetivos: 1) Analisar as relações entre as adversidades sociais e econômicas, vivenciadas durante a infância, a fase adulta e a velhice, com o baixo desempenho físico em populações idosas, de diferentes contextos sociais, econômicos e culturais. 2) Verificar a associação entre os níveis elevados da proteína c-reativa (PCR) com o desempenho físico em idosos de diferentes populações. 3) Avaliar se a desregulação nos níveis de cortisol diurno exerce influência sobre o desempenho físico em idosos com distintos perfis epidemiológicos. Métodos: Foram utilizados dados da linha de base do IMIAS – Estudo Internacional de Mobilidade no Envelhecimento, composto por 1.995 indivíduos entre 65 e 74 anos de idade, residentes em comunidades de quatro países (Albânia, Brasil, Canadá, Colômbia). O desempenho físico foi avaliado através do Short Physical Performance Battery (SPPB) e da força de preensão manual. As adversidades durante o curso da vida foram estimadas a partir de eventos e exposições sociais, econômicas e culturais ocorridas durante a infância, fase adulta e velhice. Para avaliar o percurso biológico e suas associações com a mobilidade, a proteína c-reativa e o cortisol foram considerados como biomarcadores da inflamação e do estresse, respectivamente. No sentido de responder as questões de investigações, foram conduzidas análises de estatística descritiva, bivariada e multivariada, mediante técnicas de distribuição de frequências, teste qui-quadrado, odds ratio e regressões logística, linear e multinível. Resultados: O desempenho físico foi menor nos participantes que vivem na Colômbia, Brasil e Albânia do que nos que vivem no Canadá, mesmo quando ajustados por idade, sexo e adversidades durante o curso da vida. O baixo nível de desempenho físico (SPPB < 8) foi associado a ter sofrido adversidade social e econômica na infância, ter tido ocupação semiqualificada na fase adulta, morar sozinho e possuir renda insuficiente na velhice. A PCR esteve associada com a baixa força de preensão manual e com o SPPB<8. Entretanto, a associação entre a PCR e a força de preensão manual não se manteve quando ajustada por fatores socioeconômicos e hábitos de saúde. As associações negativas entre SPPB e PCR permaneceram significativas mesmo após ajustes por idade, sexo, escolaridade, local de pesquisa e condições de saúde. O baixo desempenho físico (SPPB ≤ 8) foi associado com uma significativa diminuição nos níveis de cortisol ao acordar, em comparação com os níveis de cortisol de idosos com bom desempenho físico (SPPB > 8), mesmo após modelos controlados por local de estudo, sexo, depressão, hábitos de saúde, uso de psicotrópicos e índice de massa corporal. Conclusões: Os resultados evidenciaram associação entre a inflamação, o estresse e as desigualdades sociais e econômicas na infância, sobre o desempenho físico de idosos com diferenciados perfis epidemiológicos. Enfatizamos que a promoção do envelhecimento saudável requer considerar políticas e práticas que favoreçam o bem-estar econômico e social para crianças, adultos e idosos.

Educação profissional e tecnológica de turismo no Brasil: análise através da percepção de docentes da rede federal de educação

The increasing pace of technological change and innovation in the labor market are important landmarks that contribute to accelerate the improvement of vocational and technological education. The need to analyze the educational processes is correlated with this dynamic in order to respond to the pedagogical processes and inherent to the labor market needs in evidence. This research theme is centered on targeted education process for tourist activity that is premised on improving the quality of services, taking as analysis parameter technological higher education in the federal education network (IF), covering the design, similarity and the differences in the courses offered, the axis of Tourism, Hospitality and Leisure instituted by the National catalog Technological Colleges and the National Science and Technology Department in Brazil. The research also aims to investigate the design and implementation of these upper and search courses emphasize the importance of training for students. The research is exploratory qualitative from survey data on the websites of the Ministry of Education, was adopted as a research procedure the questionnaire sent to coordinators via institutional email courses, to collect data in order to obtain results about Technological Education Federal Education Network. The survey results show that most courses offered by technological higher education in the federal education network (IF) is the Tourism Management, we noted that this option is the result of the ease in assembling the structure of the courses in relation to others; teachers have this type of education a more practical option for students coming to the conclusion that the courses undergo a fragile process, stating that the formation lies only in the student's interest in obtaining the higher diploma course without concern for quality this academic background, demand for courses is by being fast graduation. Even as a result of the design and development of Political and Pedagogical projects it was found that they are built in the most collegial many of them without the participation of a pedagogue; about the permanence of the student identified a high dropout rate, occurring in some campuses to migration to the traditional higher education, a BA in tourism. Thus, this work aimed to contextualize the technological higher education in tourism, presenting the reality of the current situation, aiming to discuss the phenomenon from the description made by all subjects and the research object, knowledge of which is due to experience the federal education network that was able to bring the essence of the matter.

Processo identitário e saberes docentes: um estudo a partir da prática de ensino no estágio do curso de pedagogia da UFRN

Esta investigación parte del interés en la comprensión de la cuestión de los conocimientos enseñanza, precisamente el conocimiento necesario para el profesor profesional relacionada enseñanza, es decir, cuáles son los conocimientos, los profesores a construir en su contexto de trabajo. Somos conscientes de que el escenario es un momento de importancia fundamental para el desarrollo del conocimiento inicial de la profesión docente y la construcción de la identidad profesional. Tratando de entender estos aspectos nos preguntamos: ¿Qué conocimientos de los futuros profesores construyen o se movilizan durante la práctica docente desarrollado en el escenario? Nuestro objetivo es entender el proceso de identidad de estudiantes Pedagogía UFRN e identificar el conocimiento construido sobre la práctica docente desarrollada durante el entrenamiento supervisado de dicho curso. Se trata de una investigación cualitativa, y tenía como instrumento de recolección de datos, entrevistas semi-estructuradas con diez (10) en 2014.1 académicos que habían ocupado la práctica docente en el entrenamiento supervisado. Las entrevistas fueron sometidas a análisis de contenido propuesto por Bardin (2011). Como marco teórico, los autores también apoyan en tan Tardif (2012), Pimenta (2012), Nóvoa (1995), Perrenoud (2002), entre otros, se trata de la enseñanza de conocimientos dentro de la profesionalización docente, estableciendo relación con el proceso de identidad. Los resultados indican que, en lo que respecta a la identidad profesional, estudios teóricos en el curso de formación inicial, junto con las experiencias vividas en su mayoría en el escenario, contribuyeron a cambiar lo que los estudiantes sabían acerca de ser un maestro. Por lo tanto, algunos han fortalecido la identidad con la profesión, mientras que otros han renunciado a invertir en la carrera docente. En cuanto a conocimiento construido, se puede decir que los alumnos se dan cuenta de la pluralidad de conocimientos necesarios para una profesión tan compleja como la enseñanza. Sin embargo, a modo de síntesis, este conocimiento a su vez a aprender a planificar lecciones considerando las necesidades de los estudiantes y su contexto social. Los participantes declaran saber cómo llevar a cabo la mediación del aprendizaje a través del diálogo y actividades bien estructuradas y afecto contribuye al aprendizaje. En este sentido, se entiende que las construcciones de conocimiento en el escenario se articularon a reflexionar sobre su propia práctica e indican lo que era más importante en términos de aprendizaje de la percepción de los estudiantes. Sobre la base de este entendimiento, creemos que los momentos de observación (primero paso en el escenario) y el muy regencia podrían considerarse en el proceso de formación, para que los estudiantes se registre el aprendizaje proporcionado por la práctica. Es necesario, por tanto, que los estudiantes investiguen su propia actividad pedagógica, convirtiendo sus conocimientos en una continua construcción y reconstrucción de sus identidades a partir de la importancia social que conceden a la enseñanza.

A simulação como método de ensino de habilidades no curso de medicina: relato de uma experiência com punção lombar

The teaching of the lumbar puncture (LP) technique with simulator is not well systematized in the curricula of medical schools. Studies show that training in the simulator provides learning technical skills, acquisition and retention of knowledge, improve self-confidence of the learner and enables the transfer to clinical practice. We intend this study to introduce simulated training in LP in medical course at the Universidade Federal do Rio Grande do Norte evaluating the experience taking into account quantitative aspects (performance on standardized tests) and qualitative (perception of the students regarding the method and the teaching process learning). The study was conducted in two phases. In the first phase practical training in PL was introduced in the 3rd year of medical school. Seventy-seven students were trained in small groups, guided by a checklist developed in the model Objective Structured Assessment of Technical Skill (OSATS), at this moment they knew they were not under performance evaluation. They were also asked whether they had prior chances to make an LP in patients. At the end of the first phase the students evaluated training in the following areas: teaching technique, simulator realism, time available per group, number of participants per group and relevance to medical practice. In the second phase, two years later, 18 students trained in first stage performed a new LP on the mannequin simulator, and its performance was evaluated through the same checklist of training in order to verify the technical retention. In addition, they answered a multiple choice test about practical aspects of the LP technique. Each participant received individual feedback on their performance at the end of their participation in the study. In the first phase of the study we found that only 4% of students had performed a lumbar puncture in patients until the 3rd year. The training of LP technique with simulator mannequin was considered relevant and the teaching methods was thoroughly evaluated. In the second phase, all participants were successful in implementing the lumbar puncture on the mannequin simulator, compliance with the most steps in a reasonable time, suggesting that would be able to perform the procedure in a patient.

Prevalência, fatores associados e efeitos da violência doméstica na mobilidade em idosos: evidências do estudo imias (international mobility in aging study) sob a perspectiva epidemiológica do curso da vida

A capacidade de mover-se com independência e segurança é fundamental para a execução das atividades de vida diária e manutenção da qualidade de vida do indivíduo. Diversos fatores, dentre eles o envelhecimento podem contribuir para seu declínio. Estudos têm demonstrado associação entre experiências de violência doméstica (VD) e diversos problemas de saúde física e mental. Até o momento, não há estudos que tenham avaliado a associação entre experiências de VD no curso de vida e limitações de mobilidade na senescência. OBJETIVOS: estimar a prevalência da VD (física e psicológica) em idosos, e avaliar o impacto da VD no curso de vida na limitação de mobilidade. MATERIAIS E MÉTODO: Estudo observacional analítico a partir da primeira coleta de dados do estudo longitudinal International Mobility in Aging Study (IMIAS). Idosos (n = 1995) de ambos os sexos entre 65 e 74 anos de cinco localidades distintas (Kingston e Saint-Hyacinthe, Canadá; Tirana, Albânia; Maniazales, Colômbia; e Natal, Brasil) participaram do estudo. Dados sobre variáveis sociodemográficas, econômicas, condições de saúde e experiências de VD (física e psicológica) durante o curso de vida foram coletados. A limitação de mobilidade na senescência foi avaliada pelo Short Physical Performance Battery (SPPB) e pela dificuldade de andar 400 metros e/ou subir um lance de escadas. As prevalências foram avaliadas mediante frequências absolutas e relativas das exposições à VD, limitação de mobilidade e co-variáveis. Diferenças de gênero, bem como entre cidades foram analisadas utilizando o teste de qui-quadrado. Associação entre exposição à VD e limitação de mobilidade foi avaliada utilizando a regressão logística binária multivariada, ajustando pelas co-variáveis. Análise de mediação foram utilizadas, para avaliar possíveis caminhos entre a exposição à VD no curso de vida e a limitação de mobilidade. RESULTADOS: A violência física foi rara, com valores entre 0,63 e 0,85%. Relatos de violência psicológica variaram entre 3,2% e 23,5% (homens) e de 9% para 26% (mulheres). Mulheres experimentaram mais violência do que os homens em Saint-Hyacinthe (homens: 3,2% vs mulheres: 14%, p <0,001), Tirana (homens: 4,3% vs mulheres: 10,3%, p = 0,017), em Manizales (homens: 8,3 % vs mulheres: 18,3%, p = 0,004) e Natal (homens: 11,1% vs mulheres: 26%, p = 0,002). Em geral, o baixo suporte social pelo parceiro foi associado com a VD. Estar trabalhando foi associado a vitimização entre os homens, enquanto o oposto foi verdade para as mulheres. Arranjos de vida Multi-familiares e baixo suporte pelos parceiros, filhos e família foram associados com a VD. Baixo suporte social foi da maior importância para as mulheres do que os homens. A VD física foi associada tanto com o SPPB < 8 (OR 1,623 95%IC 1,161-2,269) como com a dificuldade para andar 400 metros e/ou subir um lance de escadas (OR 1,394 95%IC 1,063-1,829). A limitação de mobilidade decorrente da violência física no curso de vida pelo parceiro íntimo foi mediada pelas condições crônicas (efeito 25,56% 95%IC 0,036-0,277) e depressão (efeito 33,05% 95%IC 0,087-0,333). No caso da violência física por outros familiares, a limitação de mobilidade foi mediada pelas condições crônicas (efeito 20,85% 95%IC 0,022-0,202), não adesão à prática de atividades físicas (efeito 34,14% 95%IC 0,076-0,351) e depressão (efeito 44,40% 95%IC 0,144-0,315). CONCLUSÕES: A violência doméstica no curso de vida é uma realidade, que pode acarretar consequências que favorecem a limitação de mobilidade em idosos. São necessárias políticas públicas que combatam efetivamente a violência doméstica, garantindo um envelhecimento mais digno e independente funcionalmente.

Processo identitário profissional: as experiências formativas de licenciandos do curso de Física - UFPI

In this research, we have as study object the identification process with the profession of students of the Undergraduate course for preparing professors for teaching Physics of the Federal University of Piauí. We start from the following question: - What relationships can be established among the senses given by the students to the group of the experiences lived in their initial formation and the identity construction as teacher? The presupposition is that the process of identification with the profession can contain formative experiences that are impossible to be reduced to the situations of disciplines learning. We considered that, in the development of the process of professional identification, the articulations and the connections that the students established with themselves, with the others - their formative teachers, managers - and with the world - the University, the public school - they should be understood in the interdependence relationships, consubstantiated in the experiences lived during the initial stage of their formation. Therefore, our objective is to understand the process of identification of the students with the teaching profession, based in the senses given to their formative experiences. In order to get this aim, we used the methodology of the Comprehensive Interview, and we chose as methodological and theoretical principles: the multi-referential theoretical framework, 'configuration and interdependence', the relationship among 'identity and alterity', the sensitive hearing and the 'intellectual craft'. The study is organized in two parts: the first, contains two chapters, that have introductory character. The second part is unfolded in five chapters, and it constitutes the development of the thesis. In the "paths", we revealed, starting from the actions and intentions that mobilized the students, processes involved in the choice of the course, and, this way, the initial identifications with the being an university student. We looked for to identify possible dissonances among the curriculum 'instituted and instituting', as well as the implications of its management of the formative experiences of future teachers. In short, we tried to capture, through the speeches of a group of students, the signs, the images and the senses of their formative experiences, which indicate as a vision of how their teaching profession is built. With this study, we sought to contribute for the researches on the field of degrees, taking as axis the formative processes that configure those courses. Finally, that the proposition of professor formation politics should be fundamentally based in internal demands, lived in the formative processes.

Trajetórias construídas em caminhos (não) planejados: os sentidos formativos da escrita no estágio supervisionado obrigatório do curso de Pedagogia da UFMA

This research is taking as study aim the mediatory teaching action, its involvement with educational guidance reports of Supervised Obligatory Student Teaching in curriculum managing by formal teachers is more related to the form as each one understands the mediatory action of the pedagogy teaching activities than to the adherence of a common project, that is: the Course Pedagogy Project (CPP). Thus, our aim is meant to understand the attribution from the formal teachers to curriculum managing process, having as forms its action in the supervised obligatory student teaching at UFMA Pedagogy Course. On one side, we look for traces about established relation by them between their professional experience and their report guidance in current course. On the other hand, a research concern comes up to us on the forming meaning of the report writing by UFMA Pedagogy Teachers Course. In order to do that, we used interviews interpreted by means of methodology understanding interview. Starting from oral speeches, we understand that the managing formation in this course is linked to postures not identical and adjustable to conditions the teachers have access. We identify a curriculum subject group and a group that by their conformation adapted is considered as object group of curriculum practices. As for the mediatory action in writing formation process, we noticed that they contribute to teacher information at UFMA in the reflexive critic perspective and or in the bureaucratic reproduction perspective. The report writing at the end of the Supervised Obligatory internship is characteristic of quality quantity assessment display, as bureaucratic process and as reflexive display and didactic pedagogy activity intervention. We defend that the teachers´ guidance under critical reflections, where the writing has a social role, must overcome individual dimension, they must be debated as collective and organized practices. We hope to contribute with such a research on teacher mediatory actions and their implementing with help of reporting writing guidance in the Supervised Obligatory Student Teaching in the Curriculum Teacher managing process.

Ajustes de coeficientes integrantes de processos físicos e bioquímicos na autedepuração em curso de água de médio porte

The mathematical modeling in the simulation of self-purification capacity in lotic environment is an important tool in the planning and management of hydric resources in hydrographic basin scale. It satisfactorily deals with the self-purification process when the coefficients of physical and biochemical processes are calibrated from monitorated water quality data, which was the main focus of this study. The present study was conducted to simulate the behavior of the parameters OD, BOD5, total phosphorus, E. coli, ammonia, nitrite, nitrate and the total metals cadmium, chromium, copper, lead and zinc in the Uberabinha’s lower course (with an approximate annual growth flow between 4-35 m3/s), in a stretch of 19 km downstream of the treated effluent release by the WWTP of the city. The modelings, on the present study, show the importance of constant water quality parameters monitoration over the water course, based on the comparison of the simulations from calibrated coefficients and coefficients obtained in the literature for the period of June until November 2015. After coefficients calibration, there were good adjustments between simulated and measured data for the parameters OD, BOD, Ptotal, ammonia and nitrate and unsatisfactory adjust for the parameters nitrite and E. coli. About the total metals, the adjustments were not satisfactory on the reservoir’s vicinity of the Small Hydropower Plant Martins, due the considerable increase of the bottom sediment in lentic region. The greatest scientific contribution of this study was to calibrate the decay coefficient K and the quantification of the release by the fund S of total metals in watercourse midsize WWTP pollutant load receptor, justified by the lack of studies in the literature about the subject. For the metals cadmium, chromium, copper, lead and zinc, the borderline for K and S calibrated were: 0.0 to 13.0 day-1 and 0.0 to 1.7 g/m3.day; 0.0 to 0.9 day-1 and 0.0 to 7.3 g/m3.day; 0.0 to 25.0 day-1 and 0.0 to 1.8 g/m3.day; 0.0 to 7.0 day-1 and 0.0 to 40.3 g/m3.day; 0.0 to 30.0 day-1 and 0.0 to 70.1 g/m3.day.

Padrão de especialização comercial e crescimento econômico : uma análise sobre o Brasil no contexto da fragmentação da produção e das cadeias globais de valor

Globalization and technological changes that has happened since the 80s have brought remarkable changes in the industrial and commercial paradigm, which are expressed mainly in the international fragmentation of production and in the formation of Global Value Chains (GVC). This thesis sought to understand such phenomena and discuss new relevant variables in this context for a more accurate analysis of the current trade patterns not addressed by the seminal economic theories that relate trade and economic growth. It sought to evaluate how the trade specialization pattern of Brazil evolved compared to other economies (China, India, Russia, United States, Japan and selected Latin American economies) in the light of these phenomena from 1995 to 2011. Therefore, we have used the methodology of gross exports decomposition in value added measures, developed by Koopman et al. (2014), and indicators estimated from data of two global matrices I-O: a WIOT (2013) and the TiVA (2015). It was also tested two hypotheses regarding the role of these phenomena as determinants of economic growth in recent years: 1º) fragmentation and participation in GVC ensure higher growth rates for countries; 2º) the place (stage) in which the country finds itself in GVC associated with sectoral technological aspects is also important for economic growth. For this, we used dynamic panel models (Difference GMM and System GMM) for a sample of 40 countries from 2003 to 2011. The studies carried out on Brazil show that the country is no longer on the margins of these phenomena, because it shows increasing rates of participation in GVC, including in sectors considered most strategic for fragmentation. However, there is not a standard convergence of trade specialization of the country to those presented by developed countries or movements earned by China and Mexico in terms of their position and profile of participating in GVC. Another important result obtained by the thesis is the identification of these phenomena are in fact new variables relevant for economic growth, because it shows empirical evidences to support the hypothesis 1 and, partially, the hypothesis 2. A joint analysis of the estimated econometric results with the results of the descriptive analysis of the Brazilian economy, it leads us to conclude that the trade specialization pattern of the country in the context of the new trade setups is presented unfavorably to its growth strategy.

Caminhos da professoralidade no Curso de Dança da UFU: impasses e desafios na construção da identidade profissional

Teacher identity is a subject of study and discussion in the academic world whichhas become an object of attention of researchaddressing teaching and teacher formation. Life history, initial and continuing formation, the meaning of teaching to the teacher, and also pedagogical practice are all contributing factors to teachers’ professional identity. The present study is a proposal developed in the research field of Educational Knowledge and Practice, and its main focus lies in university teaching. Higher education teaching in the context of a dance course, and the issues and challenges of constructing teachers’ professional identity are presented. Thus, my main questions were: what is the teaching path followed by newly hired dance teachers in the Federal University of Uberlândia? How is teaching identity developed in these new teachers’ professional socialization process? What kind of educational knowledge is (re)produced and mobilized by teachers when they join university teaching? In order to answer these questions, my objectives are: to analyze the teaching path of the newly hired dance teachers of the Federal University of Uberlândia; to investigate how their teaching identity is built within their professional socialization process; and identify the kinds of educational knowledge they (re)produce and mobilize as soon as they become university teachers. The present research comprises a qualitative data analysis from previous studies on the subject, having as starting point relevant bibliographic research, followed by an identification questionnaire and an interview conducted with the newly hired dance teachers. The construction of teaching identity is related to objective and subjective conditions involving a teaching job and how the teacher perceives this identity as constantly evolving. Hence I understand the importance of personal and institutional incentives to prepare studies which raise or problematize issues specific to this area, contributing to extend the debate over higher education professionals’ formation, in particular that of dance course teachers on national scope.

Padrão de especialização e saldo comercial da China com Estados Unidos, Europa e Ásia no início do Século XXI

The rise of China has been providing various effects on developed and developing countries, particularly its Asian neighbors which compete in third markets, such as the U.S., Europe and Japan this sense, the present study aimed to analyze the pattern of Chinese trade with two different groups of countries: the Asian neighbors (Asian Tigers and Dragons) and developed countries (United States, Europe and Japan) during the 2000s. To this end, this paper adopts the methodology of second breakdown of trade technological intensity proposed by Lall (2000). Furthermore, to analyze the intensity of trade between these economies as well as potential threats over their Chinese business partners close, we calculated the following indicators of trade: Trade Intensity Index (TII), Trade Orientation Index (TOI) , Intra-Industry Trade Index (ICII), Index Of Revealed Comparative Advantage (RCA), and, finally, the Contribution To The Balance Index (ICS). The main result achieved is the existence of China\'s trade patterns differ for each group of countries, according to the type of expertise of each partner.
