L'astronomie nouvelle de Kepler et la logique de la découverte

Cette thèse propose une étude des raisons théoriques et empiriques impliquées dans l’élaboration d’une nouvelle astronomie par Johannes Kepler (1571-1630) tel qu’exposé dans son ouvrage Astronomia nova (1619). Cette thèse se déroule en deux temps : la première partie touche de près aux textes mêmes de Kepler, tandis que la seconde partie utilise la notion d’abduction pour interpréter logiquement ce processus de découverte et de justification. La première partie débute avec une analyse du projet de Kepler et de ses fondements philosophiques, métaphysiques et théologiques tels qu’exposés dans son premier ouvrage, le Mysterium cosmographicum. Ensuite, une étude des propos explicites de Kepler quant à la nature et au statut des hypothèses astronomiques est proposée via une étude de son traité intitulé Apologia pro Tychone contra Ursum. Une étude attentive des sources philosophiques, mathématiques et scientifiques ayant influencé Kepler pour sa nouvelle astronomie est ensuite proposée avant l’analyse détaillée des arguments scientifiques et des différentes étapes démonstratives qui sont présentés dans l’Astronomia nova. La deuxième partie vise à éclairer le débat sur l’abduction en se penchant d’abord sur trois approches traditionnelles (Platon, Aristote et Épicure) quant à la connaissance scientifique des phénomènes célestes permettant d’obtenir un discours vraisemblable ou une multiplicité d’explications concordantes avec les phénomènes. Enfin, quatre interprétations contemporaines et abductives du processus de découverte suivi par Kepler dans l’Astronomia nova sont présentées, reformulées et critiquées afin de proposer une nouvelle interprétation abductive laissant une plus grande place au projet même de construire une astronomie nouvelle fondée sur les causes. Cela nous donne des outils pour mieux saisir le sens et la portée de ce qui peut être désigné comme étant la « révolution képlérienne », soit le passage d’un système géocentrique à un système non pas simplement héliocentrique mais héliodynamique, ayant permis aux astronomes de s’affranchir du paradigme des orbites circulaires.

Les effets d’un cercle pédagogique sur le regard professionnel et les pratiques pédagogiques des enseignants du 3e cycle du primaire en grammaire actuelle

Notre recherche doctorale vise à décrire les effets d’un cercle pédagogique sur les pratiques pédagogiques et didactiques d’enseignants du 3e cycle du primaire en grammaire actuelle. Ce projet s’inscrit dans une recherche plus large intitulée « Étude des effets, sur les pratiques pédagogiques des enseignants et la compétence à écrire des élèves, d’un dispositif de formation à la grammaire nouvelle qui intègre des exemples de pratiques sur vidéo et permet un partage d'expertise ». Elle vise à éclairer les conditions d’efficacité d’une formation continue sur différentes dimensions du développement professionnel au regard de la formation elle-même et de son effet sur le transfert des pratiques en classe. Pour y parvenir, nous avons analysé les échanges provenant des cercles pédagogiques vécus durant une année scolaire. Nous avons également analysé deux activités de grammaire, avant et après la formation en grammaire offerte sous forme de capsules. Ces observations en classe ont été captées sur vidéo, dans la classe de 18 enseignants participant à notre expérimentation. Nous avons enfin analysé les réponses des participants à un questionnaire sur leur perception à l’égard du dispositif de formation auquel ils ont participé pendant neuf mois. Nos analyses montrent qu’un dispositif de formation à la grammaire actuelle qui met au cœur de la formation l’analyse d’exemples de pratiques sur vidéo soutient le développement du regard professionnel des enseignants dans le contexte du cercle. Ceux-ci observent plus d’interactions et les interprètent mieux, de manière plus approfondie. Nos observations ont également montré que les enseignants développent majoritairement des pratiques dans leur classe, qu’ils développent de nouveaux savoirs en lien avec le cadre théorique de la nouvelle grammaire et qu’ils modifient la vision qu’ils ont de la grammaire actuelle au fil des rencontres. Cette recherche peut enrichir les connaissances scientifiques sur le développement professionnel et influencer les formateurs d’enseignants de même que les cadres des milieux scolaires pour ajuster l’offre de formation continue afin de la rendre plus efficace.

Epidemiología de pacientes atendidos por uso de sustancias psicoactivas en el servicio de Toxicología de Colsubsidio 2011-2012

Introducción: Es una necesidad para los países del mundo, tener información epidemiológica mucho más precisa y oportuna sobre las sustancias psicoactivas (SPA), partiendo del conocimiento científico de porqué unas personas abusan de las sustancias y otras no. El objetivo de investigación es establecer el perfil epidemiológico y evolución de los pacientes consumidores de SPA que acuden al servicio de toxicología de Colsubsidio durante el 2011 y 2012. Caracterizar la población, identificar su patrón de consumo y explorar las tendencias, para poder generar estrategias dirigidas de atención y prevención. Metodología: Estudio descriptivo observacional exploratorio retrospectivo. 610 historias clínicas fueron analizadas para variables epidemiológicas y clínicas, por medio de análisis univariados acorde al tipo de variable y análisis bivariados exploratorios en los cuales se compararon proporciones. Resultados: Se evaluaron un total de 610 pacientes, 475 hombres y 135 mujeres. El promedio de edad, la mediana y la moda fue de 24,9, 17 y 16 años respectivamente; la mayoría solteros y cursando bachillerato; la mayoría menores de 18 años fueron remitidos por ICBF y psiquiatría. Los patrones de abuso y dependencia representaron los porcentajes más elevados. Las sustancias más consumidas fueron marihuana, etanol y tabaco. El tratamiento para el 44,3% de los pacientes fue valoración por especialidades, seguido de básico (33,1%), y sólo 1,1% asistieron para prevención en el consumo de SPA. Discusión: Es necesario dirigir los esfuerzos y recursos a la generación de campañas de diagnóstico temprano y prevención en el consumo de SPA principalmente para la población adolescente.

O círculo de eranos: a experiência da educação do campo ou como os contextos podem gerar

RESUMO: Estamos a vivenciar dois fatos paradoxais: de um lado, uma organização da escola instituída que gera a autoconservação das práticas do professor e, do outro, tendências nos plano científico e do discurso político que apelam ao retorno ao ator - que reconhece o professor como sujeito de seu saber e fazer. Foi neste contexto que se realizou a pesquisa subjacente a esta tese sobre a formação docente num projeto de escolarização que se fundamenta numa perspetiva de educação popular contra-hegemónica, edificada, no Brasil, como ‗educação do campo‘. Buscou-se compreender a vivência docente, suas perceções e aprendizagens. Desenvolveu-se a investigação a partir das questões: é possível, no contexto atual de mudanças sociais direcionadas ao processo cada vez maior de individuação docente, a formação em democracia participativa numa experiência de educação popular? Como ela se estabelece? O que ela nos ensina? A metodologia assentou na observação participativa das reuniões de planeamento, avaliação e replaneamento dos(as) professores(as) e coordenadores, numa proposta local de educação do campo - do Programa Nacional de Educação na Reforma agrária. As reuniões e escolarização ocorreram em Ilhéus/Bahia/Brasil, durante os anos de 2005-2006. As referências teóricas para a análise empírica do material coletado foram: a perspetiva da reflexão-ação emancipatória de Carr e Kemmis (1998), que compreende as instituições educacionais criadas por pressões sociais e políticas; e a conceção de emancipação desenvolvida por Freire e por Habermas, assente na ação comunicativa/dialógica. Para a análise utilizou-se o método da Análise Crítica de Discurso (ACD), cuja principal referência foi Fairclough. Nas narrativas das reuniões percebeu-se o desenvolvimento de uma polidez positiva – atos de fala que demonstram o falante desejando estabelecer o consenso com ouvinte; assinalada por estruturas modais que direcionaram para a abertura de relacionamento e participação mútua entre professores(as) e coordenadores do projeto. O conteúdo manifesto das falas amparou-se numa perspetiva de educador que se constrói na prática, e, ao mesmo tempo, a constrói, mas que, entretanto, necessita de aportes teóricos críticos no processo de embate epistémico entre os saberes da vida quotidiana concreta e os saberes científicos. A função interpessoal foi expressa pela arquitetura dialógica, permitindo um processo de construção mútua de escola e professores(as). Pode-se afirmar que a prática analisada indica que nestes tempos, de controlo intenso das instituições escolares, de competição, de solidão, é obviamente necessária a organização coletiva de professores (as), de movimentos sociais e universidades, amparados e financiados por ordenamentos legais (conquistados pela população), para consolidar e ampliar projetos críticos de escolarização, mudando, reciprocamente, escolas e professores(as). ABSTRACT: We are experiencing two paradoxical facts: the organization of the established school which generates the self-preservation of teaching practices and, on the other hand, there is a political and scientific trend that claims the return of the ―actor‖ – the teacher being the subject of his knowledge and actions. It was therefore in this context, that the underlying research for this Thesis was conducted. It concerns to the teacher training in an educational project which is based on the perspective of a counter-hegemonic and popular education available to people at the Brazilian countryside – also called ―Field Education‖. We searched the understanding of the educational experience, its perceptions and learning. The investigation was developed from two fundamental questions: Is it possible to have the experience of a popular education system in a functioning democracy, at the light of the recent social changes that lead to a greater individuation? How is it established? What can we learn from it? The methodology was settled on the participant observation of the planning and evaluation meetings of teachers and coordinators of the National Education Program in the Land Reform in Brazil. These meetings occurred in Ilheús- Bahia- Brazil during the years of 2005-2006. The theoretical references to the empirical analyses of the material collected were: the perspective of the reflection – action emancipative of Carr & Kemmis (1998), which comprehends the educational institutions created by social and political pressures; and the conception of emancipation developed by Freire and Habermas, which is settled on the communicative-dialogical action. For the analysis it was elected the method of Critical Analysis of Discourse (CAD),which main reference was Fairclough. During the account of the meetings it was noticed the development of a positive politeness – which reveals the desire of the speaker to reach an agreement with the listener, signalized by modal structures that directed to an open and participative relationship between teachers and coordinators of the project. The manifest content of the speeches was sustained by the educator perspective, which is built on the daily practice. However, it needs some basic theoretical contributions to the epistemic struggle between concrete ordinary life and the scientific knowledge. The interpersonal function was expressed by dialogical architecture, allowing a mutual process of construction that involves the school and the teachers. The practice analyzed indicates that, more than ever, due to the massive control of the institutions, the extreme competition and solitude, the collective organization of the teachers, the social movements and the universities is necessary. They should be supported and financed by legal systems to consolidated and amplify important education projects, bringing necessary changes for schools and teachers reciprocally.

Formação Continuada e Qualificação Profissional dos professores de Sobral – CE : múltiplos olhares

Esta pesquisa tem como objetivo analisar como a formação continuada contribui para a qualificação profissional dos professores a partir do olhar dos docentes, alunos e gestores. Buscamos o respaldo teórico dos autores como Nóvoa (2007), Tardif (2002), Pimenta (2000) e os saberes sociológicos e filosóficos de Santos (2007). A pesquisa empírica foi desenvolvida através de questionários com os diferentes segmentos da escola e análise documental referente às políticas de formação continuada dos professores adotadas pela Secretaria de Educação do Ceará. A análise dos dados buscou compreender como a formação continuada influenciou a competência docente. Os dados obtidos revelam que as propostas dos cursos de formação continuada do professor, adotadas nas escolas estaduais de Sobral-CE, embora defenda a profissionalização docente, na realidade ainda não contemplam práticas que valorizam os diferentes saberes produzidos na prática do professor e não promovem capacidade reflexiva capaz de contribuir de forma ativa e transformadora nos projetos pedagógicos, entendendo e atendendo a demanda escolar. A análise dos resultados da pesquisa evidencia a importância da parceria entre as instituições de ensino. No entanto essa parceria precisa reconhecer e valorizar culturas existentes entre a prática pedagógica e o conhecimento científico elaborado socialmente.

Edificio Lúdico de livre utilização: anti-edificio contemporâneo

A presente dissertação centra-se num estudo sobre, a conceção de um edifício lúdico, de utilização livre, sendo o projeto uma proposta atualizada e contemporânea de um edifício, relativamente utópico, que encontra no Fun Palace de Cedric Price o seu melhor antecedente. Apresenta-se uma breve referência a dois espaços sociais que sofreram influência deste anti edifício: o centro George Pompidou em Paris e Jaaga, na India. Os dois casos de estudo aqui apresentados, Downtowm Athletic Club em Nova Iorque e o pavilhão da Holanda em Xangai, revelam características relacionadas com o tema do dissertação – liberdade no espaço lúdico e enquanto locais onde o mote da sexualidade é integrado. O projeto resulta da análise das evoluções sofridas, desde 1960, no que diz respeito aos novos conhecimentos científicos que vieram contribuir para a geração de novas formas de apropriação de conceitos como é o caso do conceito da liberdade em espaços públicos e o da sexualidade. O conceito da sexualidade que evolui com os avanços que as neurociências atingem sobre o conhecimento do cérebro e das emoções e que se traduzem em novas demandas do viver contemporâneo

Planeamento estratégico de sistemas de informação em empresa de construção

Os Sistemas de Informação têm influenciado a vida quotidiana a um ritmo inesperado e com mudanças significativas na setor da construção, cuja importância é crucial para a economia de qualquer país. Sendo Angola, um país de economia emergente, caracterizado por um mercado em expansão e reestruturação, onde as decisões de Sistema Informação ainda são tomadas de forma isolada, e cada vez mais investidores estão a atuar no país, impulsionando o crescimento, é imperioso para o sector a identificação e exploração de Sistemas de Informação flexíveis e adaptáveis para fazer face as forças competitivas do setor. Partindo desta envolvente a presente dissertação visa ressaltar o reconhecimento da importância do Planeamento Estratégico de Sistemas de Informação-PESI para as organizações atuais. Neste contexto realizou-se o estudo de PESI em torno de um caso concreto numa Pequena Media Empresa, Angolana, a Terponte,SA, cujo objectivo é fornecer a construtora um plano em termos de SI para futuro. Os dados foram recolhidos através da utilização dos métodos qualitativos e quantitativos, sendo os mais pertinentes a análise documental, observação direta, entrevistas, questionários aos órgãos da empresa em estudo e demais intuições. A análise dos dados demonstrou uma deficiente gestão da informação, bem como inexistência de integração aplicacional. A presente dissertação pretende contribuir para o avanço do conhecimento científico no domínio do Planeamento Estratégico dos Sistemas de Informação e para a resolução de problemas específicos nomeadamente nas empresas do setor da construção civil.

Estudo das associações significativas e fortes dos acidentes de trabalho com o efetivo laboral e com as horas trabalhadas

O presente artigo teve como base uma aula de mestrado, em laboratório de estatística, para posterior conceção de um artigo científico, em grupo, em 4 horas. Teve como objeto de estudo a variação dos acidentes de trabalho com o efetivo laboral, com as horas trabalhadas, com a duração média da jornada de trabalho. O objetivo científico foi pesquisar correlações entre variáveis. O objetivo didático foi demonstrar os passos do método científico e o objetivo pedagógico foi quebrar preconceitos sobre a dificuldade de produzir trabalho científico. Partindo de uma sumária revisão da literatura, colocaram-se hipóteses de investigação e prosseguiu-se para tratamento estatístico inferencial sobre os dados dos acidentes de trabalho com baixa médica, do efetivo médio laboral, das horas trabalhadas e da duração da jornada média de trabalho, de uma grande empresa, durante 20 anos consecutivos. Os resultados revelaram uma associação direta, estatisticamente significativa e forte, dos acidentes de trabalho às horas trabalhadas e ao efetivo. No caso da associação dos acidentes à duração média da jornada de trabalho, a associação é estatisticamente significativa, mas de intensidade moderada. Este ensaio permitiu também intrapolar e extrapolar, com reservas, os acidentes esperados em função de uma dada carga de trabalho. As competências desenvolvidas neste trabalho revelaram-se úteis para a produção de conhecimento científico, em geral, e para gestão da prevenção dos riscos laborais, em particular. / This article was based on a master class, in statistical laboratory, of 4 hours, for subsequent group production of a scientific paper. The object of study was the variation of occupational accidents with number of employees and with hours worked, as well as with the average duration of the workday. The scientific objective has been researching correlations between variables. The learning objective was to demonstrate the steps of the scientific method, and the educational objective was to break down prejudices about the difficulty of making scientific research. Starting from a brief literature review on the subject, research hypotheses were formulated. Then, it was done inferential statistics of data regarding occupational accidents with sick leave, average number of employees, hours worked per year, and average duration of the workday, of a large enterprise, during 20 years in a row. Results revealed that there is statistically significant and strong direct association between occupational accidents and hours worked, as well as between occupational accidents and number of employees. In the case of the association of accidents to the average duration of the workday, identical data analysis revealed this association is statistically significant, but of moderate intensity. This essay also enabled to interpolate and extrapolate, with proper caution, the accidents expected to occur in a given workload. The skills developed from this research proved to be useful to create scientific knowledge, as well as to manage labour risk prevention.

New scientific paradigms for probiotics and prebiotics

The inaugural meeting of the International Scientific Association for Probiotics and Prebiotics (ISAPP) was held May 3 to May 5 2002 in London, Ontario, Canada. A group of 63 academic and industrial scientists from around the world convened to discuss current issues in the science of probiotics and prebiotics. ISAPP is a non-profit organization comprised of international scientists whose intent is to strongly support and improve the levels of scientific integrity and due diligence associated with the study, use, and application of probiotics and prebiotics. In addition, ISAPP values its role in facilitating communication with the public and healthcare providers and among scientists in related fields on all topics pertinent to probiotics and prebiotics. It is anticipated that such efforts will lead to development of approaches and products that are optimally designed for the improvement of human and animal health and well being. This article is a summary of the discussions, conclusions, and recommendations made by 8 working groups convened during the first ISAPP workshop focusing on the topics of: definitions, intestinal flora, extra-intestinal sites, immune function, intestinal disease, cancer, genetics and genomics, and second generation prebiotics. Humans have evolved in symbiosis with an estimated 1014 resident microorganisms. However, as medicine has widely defined and explored the perpetrators of disease, including those of microbial origin, it has paid relatively little attention to the microbial cells that constitute the most abundant life forms associated with our body. Microbial metabolism in humans and animals constitutes an intense biochemical activity in the body, with profound repercussions for health and disease. As understanding of the human genome constantly expands, an important opportunity will arise to better determine the relationship between microbial populations within the body and host factors (including gender, genetic background, and nutrition) and the concomitant implications for health and improved quality of life. Combined human and microbial genetic studies will determine how such interactions can affect human health and longevity, which communication systems are used, and how they can be influenced to benefit the host. Probiotics are defined as live microorganisms which, when administered in adequate amounts confer a health benefit on the host.1 The probiotic concept dates back over 100 years, but only in recent times have the scientific knowledge and tools become available to properly evaluate their effects on normal health and well being, and their potential in preventing and treating disease. A similar situation exists for prebiotics, defined by this group as non-digestible substances that provide a beneficial physiological effect on the host by selectively stimulating the favorable growth or activity of a limited number of indigenous bacteria. Prebiotics function complementary to, and possibly synergistically with, probiotics. Numerous studies are providing insights into the growth and metabolic influence of these microbial nutrients on health. Today, the science behind the function of probiotics and prebiotics still requires more stringent deciphering both scientifically and mechanistically. The explosion of publications and interest in probiotics and prebiotics has resulted in a body of collective research that points toward great promise. However, this research is spread among such a diversity of organisms, delivery vehicles (foods, pills, and supplements), and potential health targets such that general conclusions cannot easily be made. Nevertheless, this situation is rapidly changing on a number of important fronts. With progress over the past decade on the genetics of lactic acid bacteria and the recent, 2,3 and pending, 4 release of complete genome sequences for major probiotic species, the field is now armed with detailed information and sophisticated microbiological and bioinformatic tools. Similarly, advances in biotechnology could yield new probiotics and prebiotics designed for enhanced or expanded functionality. The incorporation of genetic tools within a multidisciplinary scientific platform is expected to reveal the contributions of commensals, probiotics, and prebiotics to general health and well being and explicitly identify the mechanisms and corresponding host responses that provide the basis for their positive roles and associated claims. In terms of human suffering, the need for effective new approaches to prevent and treat disease is paramount. The need exists not only to alleviate the significant mortality and morbidity caused by intestinal diseases worldwide (especially diarrheal diseases in children), but also for infections at non-intestinal sites. This is especially worthy of pursuit in developing nations where mortality is too often the outcome of food and water borne infection. Inasmuch as probiotics and prebiotics are able to influence the populations or activities of commensal microflora, there is evidence that they can also play a role in mitigating some diseases. 5,6 Preliminary support that probiotics and prebiotics may be useful as intervention in conditions including inflammatory bowel disease, irritable bowel syndrome, allergy, cancer (especially colorectal cancer of which 75% are associated with diet), vaginal and urinary tract infections in women, kidney stone disease, mineral absorption, and infections caused by Helicobacter pylori is emerging. Some metabolites of microbes in the gut may also impact systemic conditions ranging from coronary heart disease to cognitive function, suggesting the possibility that exogenously applied microbes in the form of probiotics, or alteration of gut microecology with prebiotics, may be useful interventions even in these apparently disparate conditions. Beyond these direct intervention targets, probiotic cultures can also serve in expanded roles as live vehicles to deliver biologic agents (vaccines, enzymes, and proteins) to targeted locations within the body. The economic impact of these disease conditions in terms of diagnosis, treatment, doctor and hospital visits, and time off work exceeds several hundred billion dollars. The quality of life impact is also of major concern. Probiotics and prebiotics offer plausible opportunities to reduce the morbidity associated with these conditions. The following addresses issues that emerged from 8 workshops (Definitions, Intestinal Flora, Extra-Intestinal Sites, Immune Function, Intestinal Disease, Cancer, Genomics, and Second Generation Prebiotics), reflecting the current scientific state of probiotics and prebiotics. This is not a comprehensive review, however the study emphasizes pivotal knowledge gaps, and recommendations are made as to the underlying scientific and multidisciplinary studies that will be required to advance our understanding of the roles and impact of prebiotics, probiotics, and the commensal microflora upon health and disease management.

Outward bound: women translators and scientific travel writing, 1780–1800

As the Enlightenment drew to a close, translation had gradually acquired an increasingly important role in the international circulation and transmission of scientific knowledge. Yet comparatively little attention has been paid to the translators responsible for making such accounts accessible in other languages, some of whom were women. In this article I explore how European women cast themselves as intellectually enquiring, knowledgeable and authoritative figures in their translations. Focusing specifically on the genre of scientific travel writing, I investigate the narrative strategies deployed by women translators to mark their involvement in the process of scientific knowledge-making. These strategies ranged from rhetorical near-invisibility, driven by women's modest marginalization of their own public engagement in science, to the active advertisement of themselves as intellectually curious consumers of scientific knowledge. A detailed study of Elizabeth Helme's translation of the French ornithologist Françoise le Vaillant's Voyage dans l'intérieur de l'Afrique [Voyage into the Interior of Africa] (1790) allows me to explore how her reworking of the original text for an Anglophone reading public enabled her to engage cautiously – or sometimes more openly – with questions regarding how scientific knowledge was constructed, for whom and with which aims in mind.

Introducing Undergraduate Students to Science

Understanding the scientific method fosters the development of critical thinking and logical analysis of information. Additionally, proposing and testing a hypothesis is applicable not only to science, but also to ordinary facts of daily life. Knowing the way science is done and how its results are published is useful for all citizens and mandatory for science students. A 60-h course was created to offer undergraduate students a framework in which to learn the procedures of scientific production and publication. The course`s main focus was biochemistry, and it was comprised of two modules. Module I dealt with scientific articles, and Module II with research project writing. Module I covered the topics: 1) the difference between scientific knowledge and common sense, 2) different conceptions of science, 3) scientific methodology, 4) scientific publishing categories, 5) logical principles, 6) deductive and inductive approaches, and 7) critical reading of scientific articles. Module II dealt with 1) selection of an experimental problem for investigation, 2) bibliographic revision, 3) materials and methods, 4) project writing and presentation, 5) funding agencies, and 6) critical analysis of experimental results. The course adopted a collaborative learning strategy, and each topic was studied through activities performed by the students. Qualitative and quantitative course evaluations with Likert questionnaires were carried out at each stage, and the results showed the students` high approval of the course. The staff responsible for course planning and development also evaluated it positively. The Biochemistry Department of the Chemistry Institute of the University of Sao Paulo has offered the course four times.

Understanding the "black box" of a health-promotion program : keys to enable health among older persons aging in the context of migration

Although the need to make health services more accessible to persons who have migrated has been identified, knowledge about health-promotion programs (HPPs) from the perspective of older persons born abroad is lacking. This study explores the design experiences and content implemented in an adapted version of a group-based HPP developed in a researcher-community partnership. Fourteen persons aged 70-83 years or older who had migrated to Sweden from Finland or the Balkan Peninsula were included. A grounded theory approach guided the data collection and analysis. The findings showed how participants and personnel jointly helped raise awareness. The participants experienced three key processes that could open doors to awareness: enabling community, providing opportunities to understand and be understood, and confirming human values and abilities. Depending on how the HPP content and design are being shaped by the group, the key processes could both inhibit or encourage opening doors to awareness. Therefore, this study provides key insights into how to enable health by deepening the understanding of how the exchange of health-promoting messages is experienced to be facilitated or hindered. This study adds to the scientific knowledge base of how the design and content of HPP may support and recognize the capabilities of persons aging in the context of migration.

Ouvindo as vozes na escola: análise de discurso de professores e alunos na escola de primeiro grau

Este trabalho foi desenvolvido a partir de pesquisa realizada em escolas públicas do Município do Rio de Janeiro. Procedeu-se à Análise de Discurso de professores e alunos das séries iniciais do Primeiro Grau, bem como técnicos das escolas, dos Distritos Educacionais e da secretaria de Educação. As enunciações registradas tiveram como tema principal a alfabatização, e foram analizadas com base no modelo proposto por Pêcheux, que articula três regiões do conhecimento científico: a ideológico-cultural, a linguística e a discursiva, relacionando-se o discurso e suas condicões de produção, e situando os protagonistas e o objeto do discurso. A fundamentação teórica da análise partiu das teorias linguísticas de Saussure e Beneviste, utilizando-se também os trabalhos de Baktin, Blikstein, Vital Brazil e Orlani. Segue-se a discussão em torno de aspectos da teoria da subjetividade, de natureza psicanalítica, onde foram utilizadas as teorias de Freud e Lacan. À alienação do sujeito na ordem da linguagem associa-se a alienação do trabalho, considerada por Marx e discutida no trabalho de Meszaros. As relações do sujeito com o trabalho e com a produção são também pensadas a partir dos pontos de vista de Baudrillard e Giannotti. A partir da análise das falas, propõe-se a desconstrução do simbólico e o estabelecimento dee uma nova prática, de novas relações institucionais que possam transformar o cotidiano escolar, livrando alunos e professores do assujeitamento a que ficam submetidos.

Gestão compartilhada de P&D em petróleo:a interação entre a Petrobrás e a Universidade Federal do Rio Grande do Norte

This work addresses the relationship between University-Firm aims to understand the model of shared management of R&D in petroleum of Petrobras with UFRN. This is a case study which sought to investigate whether the model of cooperation established by the two institutions brings innovation to generate technical-scientific knowledge and contribute to the coordination with other actors in the promotion of technological innovation. In addition to desk research the necessary data for analysis were obtained by sending questionnaires to the coordinators of projects in R&D at the company and university. Also, interviews were conducted with subjects who participated in the study since its inception to the present day. This case study were analysed through the Resource-Based View and Interorganizational Networks theory. The sample data also stands that: searches were aligned to the strategic planning and that 29% of R&D projects have been successful on the scope of the proposed objectives (of which 11% were incorporated into business processes); which was produced technical and scientific knowledge caracterized by hundreds of national and international publications; thesis, dissertations, eleven patents, and radical and incremental innovations; the partnership has also brought benefits to the academic processes induced by the improved infrastructure UFRN and changing the "attitude" of the university (currently with national prominence in research and staff training for the oil sector). As for the model, the technical point of view, although it has some problems, it follows that it is appropriate. From the viewpoint of the management model is criticized for containing an excess of bureaucracy. From the standpoint of strategic allocation of resources from the legal framework needs to be reassessed, because it is focused only on the college level and it is understood that should also reach the high school given the new reality of the oil sector in Brazil. For this it is desirable to add the local government to this partnership. The set of information leads to the conclusion that the model is identified and named as a innovation of organizational arrangement here known as Shared Management of R&D in petroleum of Petrobras with UFRN. It is said that the shared management model it is possible to exist, which is a simple and effective way to manage partnerships between firms and Science and Technology Institutions. It was created by contingencies arising from regulatory stand points and resource dependence. The partnership is the result of a process of Convergence, Construction and Evaluation supported by the tripod Simplicity, Systematization and Continuity, important factors for its consolidation. In practice an organizational arrangement was built to manage innovative university-industry partnership that is defined by a dyadic relationship on two levels (institutional and technical, therefore governance is hybrid), by measuring the quarterly meetings of systematic and standardized financial contribution proportional to the advancement of research. These details have led to the establishment of a point of interaction between the scientific and technological-business dimension, demystifying they are two worlds apart
