Procuramos evidenciar aqui a incongruência lógico-metodológica que perpassa pela ontologia e pela epistemologia do pensamento pedagógico de Paulo Freire. Nesse sentido, analisamos especificamente a concepção de subjetividade que portam os conceitos diálogo e conscientização. Em nossa análise, mostramos que, tanto na ontologia como na epistemologia, a concepção de subjetividade de Paulo Freire é ambígua. Paulo Freire oscila entre uma concepção de subjetividade conforme o pensamento cristão e uma outra conforme o materialismo histórico-dialético. O que, a nosso ver, inviabiliza o rigor sistemático de seu pensamento pedagógico / Mestrado / Filosofia da Educação / Mestre em Educação

Memoria para optar al Título Profesional de Ingeniero en Recursos Naturales Renovables / El Protocolo de Kioto establece compromisos de reducción de emisiones de gases de efecto invernadero a los países desarrollados, lo que ha generado un mercado de emisiones de carbono. Las emisiones de metano provenientes de los rellenos sanitarios, pueden ser reducidas si parte de los residuos que se destinan al relleno sanitario son desviadas a un proceso aeróbico, como el compostaje. El propósito de este estudio fue determinar la viabilidad técnica de un sistema de compostaje y efectuar un análisis económico preliminar que permita determinar la conveniencia al ingresar al mercado de los bonos de carbono.

The Federal Aviation Administration (FAA) is developing a new software information system -- the Surface Movement Advisor (SMA). This system development program has progressed through part of the system engineering process and is currently at a stage where additional funding will be required to complete the development. The budget for R&D at the FAA is tight and several new programs are vying for limited funds. To secure funding for further development the SMA system team must again demonstrate that it has a cost effective solution that is beneficial to the airlines and their passengers. The purpose of this project was to gather, structure, and analyze cost data and benefit information within the context of the systems engineering process as being practiced by the FAA and their SMA contractors. <p>The requirements for the SMA system are based on the fact that the developers have confirmed operational deficiencies concerning accurate and timely information about the status, position, and movement of commercial aircraft on the ground at the major airports in the country. This deficiency causes excessive and costly ground delays of aircraft. With proper information the ground controllers in the control towers will be able to direct ground traffic more efficiently and reduce the costly delays. The designers have confirmed the need for the system. They have developed feasible concepts, listed the requirements for the system, system specifications, and some preliminary designs. The systems engineers now must now decide among three design alternatives. <p>This project demonstrates a systems engineering approach to the evaluation of these design alternatives, selection of the preferred alternative and demonstration of possible benefits to justify further funding. This is the first cost and benefit analysis and many of the costs and benefits are best estimates. At later stages in the development cycle costs and benefits will be analyzed again using more current data, more accurate assumptions, and results from prototype testing and evaluation. The estimates will become more accurate in the detailed design phase in the future. / Master of Science

The need to construct a fermion quantum field theory in black-hole spacetimes is an acute one. The study of gravitational collapse necessitates the need of such. In this dissertation, we construct the theory of free fermions living on the static Schwarzschild black-hole and the rotating Kerr black-hole. The construction capitalises upon the fact that both black-holes are stationary axisymmetric solutions to Einstein's equation. A factorisability ansatz is developed whereby simple quantum modes can be found, for such stationary spacetimes with azimuthal symmetry. These modes are then employed for the purposes of a canonical quantisation of the corresponding fermionic theory. At the same time, we suggest that it may be impossible to extend a quantum field theory continuously across an event horizon. This split of a quantum field theory ensures the thermal character of the Hawking radiation. In our case, we compute and prove that the spectrum of neutrinos emitted from a black-hole via the Hawking process is indeed thermal. We also study fermion scattering amplitudes off the Schwarzschild black-hole. / Ph. D.

"Only with the language of the present can we get the past to speak." Sverre Fehn "A poet doesn't produce a different language for each poem. That's not necessary; he uses the same language, he uses even the same words. In music it is always the same instruments most of the time. I think that is the same in Architecture." Mies van der Rohe ' ...within this structure,... the elements 'keep one another in a state of equilibrium in accordance with fixed rules', and ' a language is a system in which the value of any one element depends on the simultaneous coexistence of all the others'." Ferdinand Saussure The connection of one building to another can be seen through a universal architectural language. Buildings are structured through the use of this language. Architecture communicates thoughts and ideas through the elements of building. The architect may show us things very subtly or dramatically using this language. Light, wind, material, color, water, even a wall are only a few of the elements of architectural discourse. Like letters form words and words form sentences, architectural elements are placed in order from which a possible meaning derived. The relationships between elements tell stories of different kinds. Within the structure of the architectural language the elements remain the same; their configuration, however, changes to reveal new and different meanings. Configuration is various; the use of these elements link past to present. Language A. Structure 1. Syntactic 2. Semantic 3. Pragmatic B. Elements 1. Letter 2. Word Architecture A. Structure 1. Syntactic 2. Semantic 3. Pragmatic B. Elements 1. Materials 2. Columns, walls, roof, floor, light, etc. / Master of Architecture

This study began with the desire to design a public town library of the future and became a search for an inkling of what is essential to Architecture. It is murky and full of contradictions. It asks more than it proposes, and the traces of its windings are better ordered through collage than logical synthesis. This study is neither a thesis nor a synthesis. When drawing out the measure of this study it may be beneficial to state what it attempts to place at the perimeter. Architecture is not a product of society, civilization, or economy. Architecture is not democratic, and it cannot be brought forward in the public realm. Architecture is not a private affair. Architecture is not space, and it is not building. This study does attempt to hold that Architecture is founded in speech and gesture which originate in culture. As 'constructions' (construings), Architecture and the book share with the body the potential for utterance. The library is the coincidence of Architecture, the book, and the body. / Master of Architecture
