Da polêmica sobre a pós-modernidade aos 'desafios' lyotardianos à Filosofia da Educação

As relações entre pós-modernidade e educação tem sido objeto de inúmeras pesquisas, bem como de certa polêmica no âmbito da Filosofia da Educação, a começar pela própria conceituação da pós-modernidade até chegar às posições filosóficas engendradas por ela. em quase todas essas pesquisas e polêmicas, A condição pós-moderna, de Jean François Lyotard, se configura como uma referência importante, porém raramente as obras subseqüentes a essa são mencionadas, deixando uma parte de seu legado filosófico de fora de tais discussões e, particularmente, de suas eventuais contribuições para a educação. Tendo em vista esse limiar dos estudos sobre o assunto, o presente artigo procura desenvolver uma interpretação acerca do pensamento lyotardiano, privilegiando a análise das obras subseqüentes ao seu livro mais polêmico, com o objetivo de situar o seu projeto filosófico para além de um marco da pós-modernidade e de discutir as suas contribuições à Filosofia da Educação na atualidade. Mediante tal interpretação, recupera-se um projeto filosófico que lança alguns 'desafios' à Filosofia da Educação referentes ao deslocamento de sua problemática epistemológica para a estética, nutrida por um pensamento capaz de elucidar a face complexa e obscura da educação, a sua sombra inumana, e o diferendo constitutivo do ensino, inapreensíveis pela linguagem e pela comunicação. Assim, esperamos que tal projeto possa ser compreendido não por aquilo que traz de polêmico à Filosofia da Educação, mas pelo que a desafia no tempo presente, como uma reescrita da modernidade.

Simulation of the energy performance of maize production integrated to pig farming

Foi avaliado o desempenho energético da suinocultura integrada à produção de milho em grão em sistema de plantio direto mecanizado. Nesta concepção de integração proposta, os dejetos suínos são utilizados como fertilizantes na produção de milho. O sistema foi delimitado envolvendo as atividades associadas ao manejo dos suínos e de produção do milho (manejo do solo, cultivo e colheita). O período de análise considerado foi de um ano, o que possibilita a produção de três lotes de suínos e duas safras de milho. Para avaliar o desempenho energético, foram criados três indicadores: eficiência energética, eficiência de uso de fontes não renováveis e o custo de energia não renovável para a produção de proteína. As entradas energéticas são compostas pelos insumos e pela infraestrutura, utilizados na criação dos suínos e na produção de milho, e pela radiação solar incidente no agrossistema. Já as saídas são representadas pelos seus produtos (suínos terminados e o milho). Os resultados obtidos nas simulações apontam que a integração melhora o desempenho energético das granjas suinícolas, aumentando a eficiência energética (186%) e a eficiência não renovável (352%), além de reduzir o custo de energia não renovável para a produção de proteína (‑58%).

Vargas e Prestes: uma comparação entre o trabalhismo e o comunismo no Brasil

Este texto veio a constituir parte do segundo capítulo de nossa tese de Mestrado - O Ato Livre: considerações a respeito da política operária - Faculdade de Filosofia, Letras e Ciências Humanas, Universidade de São Paulo. Nele, procuro mostrar a impressionante semelhança de pressupostos teóricos subjacentes tanto a um discurso que articula a concepção burguesa das relações sociais, criado para o controle da c/asse operária, quanto a seu suposto oponente, que articularia a concepção socialista e que, explicitamente, estaria desenvolvendo o ponto de vista marxista. Com esse objetivo, cotejo os discursos de Getúlio Vargas (pronunciados nos anos de 1946 e 1947) com os quase contemporâneos discursos de Luis Carlos Prestes (escritos em 1945). Concluo com uma breve reflexão a respeito da origem desses pressupostos no interior do movimento comunista internacional.

Os elos entre a filosofia e a educação no pensamento de Theodor W. Adorno

Este artigo aborda as relações entre a filosofia e a educação no pensamento de Theodor Adorno. A partir da reflexão elaborada pelo frankfurtiano acerca da relação entre teoria e práxis, procuramos compreender o papel político conferido às suas concepções de filosofia e de formação humana e discutir os seus limites e possibilidades no presente. Para tanto, elegemos como objeto de análise as conferências pronunciadas pelo autor e os artigos que escreveu sobre o assunto, entre 1959 e 1969, com o objetivo de recuperar os possíveis nexos teóricos entre filosofia e educação em sua obra e o significado que seu pensamento crítico e sua concepção de educação política assumiram nesse contexto; e de discutir sua eventual atualidade. Pretendemos, assim, reconstituir a reflexão de Adorno sobre o tema, compreendendo o seu significado em seu projeto filosófico, de modo a vislumbrar a face filosófica educacional de seu pensamento crítico.

Modeling for performance analysis of electromagnetic zero-sequence suppressor

The purpose of this work is to present a frequency domain model to demonstrate the operation of an electromagnetic arrangement for controlling the injection of zero-sequence currents in the electrical system. Considering the diversity of sequential distribution of harmonic components of a current, the device proposed can be used in the process of mitigation of zero-sequence components. This device, here called electromagnetic suppressor, consists of a blocker and filter both electromagnetic, whose joint operation can provide paths of high and low impedances that can be conveniently adjusted in order to search for a desired performance. This study presents physical considerations, mathematical modeling and computer simulations that clearly demonstrate the viability of this application as a more viable alternative in the conception of filtering systems. The performance analysis is based on the frequency response of harmonic transmittances. The efficacy of this technique in direct actions to maximize the harmonic mitigation process is demonstrated. ©2010 IEEE.

A sound education: Becoming aware of the sound around us

In this article it is intended to discuss the issue of noise pollution from an unusual point of view: noise pollution is not only the result of sound increase worldwide, but, particularly, the poor quality of our listening habits in modern life as well. In contemporary society we are subject to a considerable amount of stimulus to all our senses: vision, scent, taste and hearing which are becoming more and more insensible due to over exposure in our environment. These increased stimuli make us look for alternatives to reduce our ability to perceive them and be protected from injuries. However, our sensitivity will also decrease. In the specific case of environment noise, over exposure has made us forget the enchantment of certain sounds that used to give us pleasure or evoke good feelings by many ways, making us recall certain good things, bringing particular moments of our lives to our memory or even filling us with strong emotion. The Canadian composer and music educator, R. Murray Schafer, believes that noise pollution is the result of a society who became deaf. Closing our ears to noise protect us from noise pollution but also prevent us from grasping subtleties of listening. Contemporary world does not help us to be aware of sound in the space around us; acquiring this hearing ability is a matter of focus, interest and practice. Sound education exercises are aimed at children, teenagers and adults who want to improve their listening ability to environmental sounds, perceive its proprieties and learn how sound affects us and touches our feelings. The results are easy to accomplish and contribute to our awareness of the sound environment around us and to the conception of the environmental sound as a composition made by everybody and everything through positive actions, strong will and high sensitivity.

Design and development of a low-cost solar tracker

To become competitive, ultimately, photovoltaics should have its costs reduced and use photovoltaic systems of greater efficiency. The main steps in this direction are the use of new materials, the improvement in the manufacture of modules and the adoption of techniques of maximum power point tracking and of solar tracking. This article aims at presenting the project and development of an azimuth and elevation solar tracker, based on a new conception of the positioning sensor, composed of an array of four photoresistors. The two direct current motors that operate in the vertical and horizontal axes are controlled by a proportional-integral microcontroller. The conditions of the project were low cost, small energy consumption and versatility. The microcontroller can also incorporate a maximum power point tracking algorithm. The performance of solar tracker prototype in the initial phase of field tests can be considered appropriate. © Institution of Engineers Australia, 2013.

Assessment of the damage caused by flood rains and landslides in association with hurricane Michelle, october 2001: implications for economic, social and environmental development

Preface This study was prepared for the Government of Jamaica following the significant physical damage and economic losses that the country sustained as a result of flood rains associated with the development of Hurricane Michelle. The Planning Institute of Jamaica (PIOJ) submitted a request for assistance in undertaking a social, environmental and economic impact assessment to the Economic Commission for Latin America and the Caribbean (ECLAC) on 14 November 2001. ECLAC responded with haste and modified its work plan to accommodate the request. A request for training in the use of the ECLAC Methodology to be delivered to personnel in Jamaica was deferred until the first quarter of 2002, as it was impossible to mount such an initiative at such short notice. This appraisal considers the consequences of the three instances of heavy rainfall that brought on the severe flooding and loss of property and livelihoods. The study was prepared by three members of the ECLAC Natural Disaster Damage Assessment Team over a period of one week in order to comply with the request that it be presented to the Prime Minister on 3 December 2001. The team has endeavoured to complete a workload that would take two weeks with a team of 15 members working assiduously with data already prepared in preliminary form by the national emergency stakeholders. There is need for training in disaster assessment as evidenced by the data collected by the Jamaican officials engaged in the exercise. Their efforts in the future will be more focused and productive after they have received training in the use of the ECLAC Methodology. This study undertakes a sectoral analysis leading to an overall assessment of the damage. It appraises the macroeconomic and social effects and proposes some guidelines for action including mitigating actions subsequent to the devastation caused by the weather system. The team is grateful for the efforts of the Office of Disaster Preparedness and Emergency Management (ODPEM), the associated government ministries and agencies, the Statistical Institute of Jamaica (STATIN), the Planning Institute of Jamaica and the Inter American Development Bank (IDB) for assistance rendered to the team. Indeed, it is the recommendation of the team that STATIN is poised to play a pivotal role in any disaster damage assessment and should be taken on board in that regard. The direct and indirect damages have been assessed in accordance with the methodology developed by ECLAC (1). The results presented are based on the mission's estimates. The study incorporates the information made available to the team and evidence collected in interviews and visits to affected locations. It is estimated that the magnitude of the losses exceeds the country's capacity to address reparations and mitigation without serious dislocation of its development trajectory. The government may wish to approach the international community for assistance in this regard. This appraisal is therefore designed to provide the government and the international community with guidelines for setting national and regional priorities in rehabilitation and reconstruction or resettlement programmes. A purely economic conception of the problem would be limited. A more integrated approach would have a human face and consider the alleviation of human suffering in the affected areas while attending to the economic and fiscal fallout of the disaster. Questions of improved physical planning, watershed management, early warning, emergency response and structural preparedness for evacuation and sheltering the vulnerable population are seen as important considerations for the post disaster phase. Special attention and priority should be placed on including sustainability and increased governance criteria in making social and productive investments, and on allocating resources to the reinforcing and retrofitting of vulnerable infrastructure, basic lifelines and services as part of the reconstruction and rehabilitation strategy. The Jamaican society and government face the opportunity of undertaking action with the benefit of revised paradigms, embarking on institutional, legal and structural reforms to reduce economic, social and environmental vulnerability. The history of flood devastation in the very areas of Portland and St. Mary shows a recurrence of flooding. Accounts of flooding from the earliest recorded accounts pertaining to 1837 are available. Recurrences in 1937, 1940, 1943 and 2001 indicate an ever-present probability of recurrence of similar events. The Government may wish to consider the probable consequences of a part of its population living in flood plains and address its position vis-à­¶is land use and the probability of yet another recurrence of flood rains.
