Obtenção e caracterização óptica e elétrica de 'La''Ta'O IND.4' e LiTaO Ind.3 puros e dopados com Eu POT.3+

Eletronicalceramics are used in many applications such as: multilayer capacitor, transducer, pyroelectric sensors and electrooptic devices. In recent years there has been a growing demand for eletronicalceramics with better performance and functionality. This demand has accelerated the development of synthesis techniques to produce powders with well-defined particle size, shape and crystallinity. The eletronicalceramics in the form of bulk are determined by their performance characteristics of the powders used and the preparation process. So, physical and chemical properties of powders, such as chemical control of stoichiometry, purity, homogeneity, particle size and shape should be observed when choosing the methods of synthesis. Among the techniques used so far, the polymeric precursor method, also known as Pechini, has been considered ideal for the preparation of nanosized powders. Thus, this research project aims to use the polymeric precursor method to prepare powders of lithium tantalate and lanthanum tantalate, with good chemical stability. In this aspect is proposed to investigate the effects of variation of the concentration of europium about the properties of tantalate because doping with Eu3 + indicates that they may occupy different sites in the crystal structure, as in the case of LiTaO3. Effects of things like occupation sites, stability of phases and formation temperature have been previously investigated by the group, which motivated the formulation of this project. Our proposal aims to introduce the Eu3 + LaTaO4 and LiTaO3 and study the structural and optical properties of the powders obtained by Pechini method, as well as correlate these studies with the electrical properties of the material, mainly the Ironelectricty Hysteresis.

Estilo de liderança e stress: uma pesquisa em escolas estaduais de ensino fundamental

This survey attempted to find out whether or not the management styles adopted by schools can be associated with teacher stress. The study considered 175 teachers working with 1st‑to 4th grades in twelve public schools. The instruments first identified the leadership style predominant in the schools, then sought to identify the presence of stress in the teachers. Although stress was present in the majority of the teachers, an association with specific management styles could not be confirmed. This can be linked to the fact that the stress was already present in the teachers and did not allow the identification of additional influence by the schools’ leadership style

A pesquisa de iniciação científica como espaço de formação inicial de professores e pesquisadores de Biologia

This paper discusses a study conducted the systematic monitoring of scientific initiation activities in a research group in Epistemology of Biology. The objective was to investigate the evolution of undergraduate ideas about epistemological, historical and didactic aspects from Biology during the development of research projects. Data collection occurred through the use of various instruments, such as written materials and interviews. The results suggest that involvement in research activities and the interaction in the group allowed to the participants the development of critical thinking, by means of collective reflection and individual significance of biological knowledge located in different contexts epistemological, historical and didactic.

Pesquisa etnográfica com crianças: caminhos teórico-metodológicos

This paper discusses methodological issues in educational research with young children. It approaches qualitative ethnographic research, highlighting participant observation as one of the most appropriate strategies for research developed in schools for children in the first two years of basic education, in other words, students between six and seven years old. It is suggested that ethnographic research and participant observation can diminish the differences between observer (adult) and observed (kids), when considering the peer culture in childhood , allowing the researcher to insert itself in a more properly way on a cultural reality of a given group. Furthermore, it is necessary to respect ethical principles, consider the specificities of young children and use various strategies to generate empirical data in order to enable them to participate more actively in educational research in which the object of study is childhood. Thus, young children could be recognized as producers of knowledge and subject of the investigative process.

Pesquisa aplicada em comunicação: uma tendência necessária

The history of communication as a science was marked by different moments. The first one was built by technological experimentation and later, by language transformation. But the consolidation of communication as applied social science has come from theoretical research, when Lasswell and Lazarsfeld respectively proposed the hypodermic and the two-step flow theories. However, applied research – which involves experimentation and its observation in a practical application process – is once again being targeted by the academy. This text develops an essay on the importance of applied research to the development of contemporary communication, presenting examples and methods related to such reality.

Interpretando la estrutura curricular de programas brasileños de licenciatura en Física, a partir de una perspectiva epistemológica de la Didáctica de la Física

This study aims to contribute to understanding the complexity related to the definition and practice of "Didactics of Physics" in initial physics teachers training. We intend to make evident how is understood the Didactics of Physics in curricular organizations, since an "observation" from a perspective based on an analysis of theoretical frameworks of Science Teaching, according to which "Didactics of Physics" is an articulating axis between different disciplines and constitutes the knowledge body to be taught in order to teachers learn to teach physics. For that, we used techniques of documentary analysis, constituting a text from a systematic search of information about Physics teachers’ initial education programs, looking for criteria justifying their organizations and contents of disciplines that aim to contribute to the training for teaching, in a study carried out during 2011. We found on these curricular organizations the presence of disciplines in fields such as: Exact Sciences, Humanities, Social Sciences and Teaching Practice, which indicates a consideration of interdisciplinary training which must receive the future teacher. However, without being consistent with Science Education' epistemology, requesting the integration of interdisciplinary knowledge to solve problems related to teach physics in high school, with some exceptions in the preparation for the subject "traineeship" or training for "Didactic transposition", but since different interpretations.

Formación de profesores en Educación Física en Brasil: comprensión de estudiantes noveles de la Universidad Federal de San Carlos

The frequent characterization about the Physical Education Degree is associated to technical-sport and training aspects and this is the reason of this study. The objective is to understand the motives to the basis of this situation. In this sense, a theoretical study was developed regarding the Physical Education Teaching Training in Brazil; at the same time, an empirical investigation was carried out with first-year students of the cited degree. The register tool to collect the students' understandings was an open question expressed as: "Why did you choose the course of Physical Education Degree?" which was answered in written form by the students. So as to make up an understanding of the data collected, the information was organized in two thematic categories; Category A: no identification with schooling; Category B: reasons in relation to the (lack) of professional vocation. Based on the students' answers, it was possible to comprehend that choosing the mentioned degree it is mostly set up by a lack of option, instead of a real professional identity and thoughtful processes of transformation in society.

Miedo e inseguridad de la gestante durante el trabajo de parto como motivos para la demanda de internación precoz

Objective. To identify reasons why women look for early health care attention at the end of pregnancy. Methodology. Qualitative study based in socio-existential phenomenology proposed by Alfred Schütz. Nine pregnant women who consulted to the maternity service without being in real labor were interviewed. Results. The following analysis categories emerged: Having different symptoms or signals from the ones they had felt or been informed about, not being able to identify real labor, fear to fetal complications for being close to the probable labor date, feeling calmer when being seen by professionals of the institution, lack of problem solving by other services of the health institution, fearing out of hospital delivery, imitating real labor, looking for tranquility in the idealization of labor and modifying behaviors to guarantee attention. Conclusion. Women are insecure and fear because of a fragmented health care, where they do not perceive themselves linked to the prenatal control program anymore, and at the same time they don’t find the health care assistance they want.

Impactos da legislação na pesquisa etnobotânica no Brasil, com ênfase na região amazônica

The Amazon region has a large sociobiodiversity, where lives people with traditional knowledge about the uses of its natural resources. The Convention on Biological Diversity (CBD) in 1992 recognized the autonomy of each nation over its genetic resources and the rights of traditional populations about the knowledge of the use of these natural resources. In 2001 it was published the law M.P. 2.186-16/2001 which created the Conselho Nacional de Gestão do Patrimônio Genético (CGEN) and the first rules about access to genetic resources and associated traditional knowledge in Brazil. Since his creation, the actions of CGEN have received criticism from various sectors, both private and public, and, unlike its initial proposal, has become one of the main obstacles of ethnobotanical studies, the bureaucracy, the long process analysis and communication difficulties with this organ.
