Title: A doença de Alzheimer como prioridade de pesquisa na Agenda de Pesquisa em Saúde: análise da pesquisa brasileira e latino-americana Author(s)/Inventor(s): Silva, Angelina Pereira da Advisor: Leta, Jacqueline Abstract: The growing trend of population aging and the increasing number of people with Alzheimer’s disease impact socioeconomic and health systems. Health research has become a central element in addressing priority health issues. Health Research Agendas strategically define priorities based on each country’s health condition, encourage research, and generate scientific knowledge to meet population needs. Thus, the objective of this thesis is to investigate research on Alzheimer’s disease before and after the implementation of the Health Research Agenda in Brazil using three strategies: mapping various characteristics of scientific production, detailing technical and scientific aspects associated with the Brazilian and Latin American Health Research Agendas, and identifying the perceptions of health science, technology, and innovation managers and Brazilian researchers regarding the impact of the Agenda on research. This is a quantitative-qualitative study based on the collection and analysis of quantitative data on scientific production indexed in the Scopus database for the periods 1974-2005, 2006-2019, 1986-2004, and 2005-2023, data obtained from documents and semi-structured individual interviews, on which documentary analysis and content analysis were conducted. The results indicate an increase in the number of original and review articles published in health science journals, authored by researchers affiliated with institutions in Brazil’s Southeast region. Journal co-citation analysis revealed that Brazilian research on Alzheimer’s disease was initially based on 72 journals focused on health sciences, but after the implementation of the Agenda, this number grew to 679 journals, covering a broader range of disciplines. Author co-citation analysis identified 93 co-cited authors in distant clusters from 1974-2005, while between 2006- 2019, 1,000 co-cited authors formed more interconnected clusters. Keyword co-occurrence analysis highlighted the growth of Brazilian and Latin American scientific production and the diversification of research topics following the implementation of the Agendas. Documentary analysis indicated that among the 47 countries in the region, only Argentina, Brazil, Colombia, El Salvador, Ecuador, Guatemala, Honduras, Mexico, Panama, Paraguay, Peru, the Dominican Republic, and a few Caribbean nations have established research agendas that prioritize Alzheimer's disease. Content analysis revealed that managers and some researchers recognize the Agenda as a permanent and sustainable public health policy tool that has driven health research activities in the country. However, a lack of dissemination, institutionalization, and updates compromises its effectiveness. The analysis of scientific production, Research Agendas, and interviews demonstrates that, while the Health Research Agenda has strengthened Alzheimer’s disease research in Brazil, its continuous updating is essential to guide priority research and serve as a reference for funding. In addition, the findings of this study highlight the need for increased investment and adequate infrastructure as fundamental measures to ensure that Brazilian science continues to advance in Alzheimer’s disease research and other health conditions.

Title: A ciência, os cientistas e a dupla hélice sob o olhar de estudantes Author(s)/Inventor(s): Massarani, Luisa Advisor: Lent, Roberto Abstract: Analyse aspects of scientific culture in Brazil, considering as starting point quantitative and qualitative studies undertaken among high school and undergraduate students in Rio de Janeiro. We analysed 1,065 questionnaires, 455 of them completed by students of five courses of the Federal University of Rio de Janeiro (Social Sciences, Biology, Medicine, Engineering and Physics) and 610 by students of nine high schools (370 of them 370 of them attended government schools and 240 private schools). This first section of the research aimed to investigate the attitudes that young people have towards science, scientist's work and applications and consequences of scientific research. We also analysed the point of view these students have towards new technologies and uses of modem genetics. The role of genes in the development of individual characteristics has been considered too. A focus group method was used with GATTACA, a science fiction film, the catalyst for discussion. The research doesn't seek to be a representative sample of the Brazilian students' population or even of Rio de Janeiro. It is a case study, in which we provided a descriptive study of the analysed groups and discussed the results we obtained. in our reflections we have taken in to account several conceptions concerning scientific culture which were supported by observations and analysis of the context of the mass media in which these young people were placed. Some possible implications of the results for the popularization of science activities are also discussed. Publisher: Universidade Federal do Rio de Janeiro Type: Tese

Title: O bom e o mau professor na ótica dos estudantes dos níveis de ensino fundamental, médio e de graduação Author(s)/Inventor(s): Pereira, Marcia Rodrigues Advisor: Foguel, Debora Abstract: The predominant categories in the students' good and bad teachers classification in ali school leveis studied was "Descriptions of the teaching process", "Physical and personal characteristics of a teacher" and "Quality of relationship between teacher and student", always in this arder. ln ali situations studied, this group of categories represented 90% of the total students responses. This result led to a perception of this group of categories importance in the good and bad teacher classification. No correspondence has be found between the student preferences of their teachers and the teachers subject. So it is possible to suggest that the students preference was related to the teaching way instead the subject taught. Then the teachers communication capacity stands out distinctly because permits to the teacher constructs a significant communication process in his/her classes with effective learning by the students. The good teacher qualities seems possible trainable and although the teachers work could be enriched by refined equipment for the schools that improve considerably the learning process the teachers characteristics should more important to the success of learning process. At first view it was no correspondence between teachers sex by pupils sex and the good and bad teachers classification. Publisher: Universidade Federal do Rio de Janeiro Type: Dissertação
