1. Aspectos Epistemológicos, Históricos y Didácticos del Conocimiento Profesional del Profesorado Universitario de Probabilidad
Educational research has highlighted the need for further research into the knowledge base of university teaching faculty, which needs to go beyond a mere familiarity with mathematical content. What is termed University Teaching Faculty Professional Knowledge would include aspects related to the current teaching of the discipline, such as the perspectives of

2. Las matemáticas para la enseñanza en una formación del profesorado basada en el estudio de cuestiones
We present a proposal for the training of secondary school mathematics teachers, within the framework of the Anthropological Theory of the Didactic. Following Cirade (2006), the educational proposal is based on the study of questions that emphasizes the problematic character of school mathematics and calls for the construction of new mathematical praxeologie

3. Propostas de formação inicial de professores de matemática : um estudo de projetos político-pedagógicos de cursos no Estado do Paraná
With this work we investigate proposals for teacher education in current political-pedagogical projects (PPPs) for licenciateship in Mathematics in the state of Paraná. Of the 29 PPPs in this state in 2007 and 2008, we had access to 15 of these and we propose to examine six. This is a documental study, characterized as qualitative research according to Bogd

4. Paraconsisted computation : a logic approach to quantum / Computação paraconsistente : uma abordagem logica a computação quantica
This work provides evidences to view computational complexity as logic-relative, by introducing new models of computation through non-classical logics and by studying their features with respect to computational expressivity and efficiency. From this point of view, we suggest a new way to study the efficiency of quantum computational models consisting in the

5. Avaliação experimental da sincronização por densificação de grupos de pedestres em passarelas
Footbridges are special works of art, present in large urban centers and along the highways. They are built above the roads to improve the safety of pedestrians and facilitate the flow of traffic, since they eliminate the points of conflict between pedestrians and vehicles. The occurrence of the phenomenon lock-in has implied the closing for repair of footbr

6. Leitura, interpretação e resolução de problemas matemáticos de estruturas aditivas
This research, attached to the search line "teaching practices and its relationship with the teacher training," aimed to describe and to analyze the performance and ways of solution of the problems of mathematical addition structures with pupils of the elementary school, related to their reading and their interpretation as a way to identify the relationships

7. Estudo do modelo de famÃlias de distribuiÃÃes de probabilidade baseado em programaÃÃo matemÃtica
Since immemorial times, man has learned to deal with uncertainty in trying to prevent losses derived from unexpected factors. Several probability theories were proposed in such a search, KolmogorovÅs having been the most used. However, it fails to serve a number of situations. A great deal has been done in order to work out the situations where the classic

8. Uma extensÃo a teoria matemÃtica da evidÃncia
This work makes an extension to the Mathematical Theory of Evidence, also known as the Dempster-Shafer Theory, by the adoption of a new rule of evidences combination and a companion set of concepts. This extension solves the counter-intuitive problems shown by the original theory, extends its expressional power and allows the representation of the uncertain

9. Biomechanics load transmission single implants according to prosthetic materials photoelastic and dinamic analysis / "Biomecânica da transmissão de cargas a implantes unitários em função dos materiais protéticos: análise fotoelástica e dinâmica"
Less rigid oclusal materials such as acrylic resins are often used in prosthesis over implants because they are supposed to diminish the loads transferred to the bone; however there is no scientific evidence to support this theory. The objective of this work was to compare by photoelastic and dynamic analysis the load transfer after oclusal loads over single

10. Estudos sobre modelos de crescimento populacional e modelos econômicos
The fundamental purpose of this thesis is to propitiate some thoughts and contributions os theoric, conceptual, critical and methodological order about the population growths models and economical models considering the interaction established between those models and the Economic and Social Development. From this perspective, different existing concepts wer

11. Remarkable statistical behavior for truncated Burgers–Hopf dynamics
A simplified one-dimensional model system is introduced and studied here that exhibits intrinsic chaos with many degrees of freedom as well as increased predictability and slower decay of correlations for the large-scale features of the system. These are important features in common with vastly more complex problems involving climate modeling or molecul

12. Mathematical theory of group selection: Structure of group selection in founder populations determined from convexity of the extinction operator*
Genetic analysis for group selection is developed for the case of a biallelic locus (A, a) undergoing group selection of founder populations only. By contrast to R. Levins“E = E(x) models, extinction now depends on genetics at the propagule stage but acts uniformly on larger populations. Biological evidence supports this hypothesis, which also allows mathe
