This article discusses the policy implications of agricultural modernization implemented by the military - after 1964. This policy, which became known as the Green Revolution, on the one hand contributed to the development of big business, but another caused serious social and environmental impacts. Currently, not only in Brazil but all over the world, have been in a great debate about the need to find alternatives to contain the problems caused to the environment resulting from the use of high technology in the field. One alternative proposed by several researchers is to replace fossil fuels by biofuels. As we believe that the error is in the current model of agricultural production based on mass production, which serves the major markets, the attention in this article, the need to develop an agricultural model designed for small property, with the use of family work and agroecology.

This paper addresses the issue of access the industrial heritagerailway information integrating the EFNOB in the city of Bauru / SP, through the use of new technologiesinformation. For constitute a major challenge in gathering, organizing, scanning and providing such documentary collection, the research aims to organize and disseminate information document, supported by new access technologies, aiming to preserve and create conditions for setting up a database of documents and cartographic this collection. This research is part of our project entitled "EFNOB Bauru: Center for Memory and Virtual Information", which in turn is part of the larger project, called "EFNOB / Bauru, Km 0," FAPESP / CONDEPHAAT. One of the cornerstones of the work is to collect, treat, select and the heritagedisseminate of movable and immovable EFNOB through the creation of a MemoryCentre and Industrial HeritageRailwayInformation of EFNOB.

The incipient but quickly expansion action on the Information and Communications Technologies (ICT) in Africa it is now just having different impact on these societies. One of these relates bear on how users are identified with these tools. Just like that we find individuals identify as bloggers, twitter followers or cyber activist. This contribution analyzes the Senegal’s fact where a successful use of social nets and web 2.0 tools experience (at least in repercussion) as social and political involvement while presidential elections in 2012 is tied to come back an identity: Cyber activist. Senegalese circumstance shows us how this identity has a personal and assertiveness dimension as well collective aspects of belonging to a community. One as much as the other, show us personal traits in contrast to previous beliefs, basically because it fuse and confuse virtual and reality. Due to dynamics from expanding technology, this identity is youthful and urban, but not only. This situation creates new dynamics at least in this affected group. For this reason, besides knowing emergence and evolution of this fact, it raises some of the involvement in social and political involvement from groups traditionally “invisible”. Beyond the new social behavior there are new changes in the rules of the game in order to start new social revolution.

O presente artigo apresenta as contribuições do programa Pró-Letramento em Matemática para um grupo de professores cursistas. Sob diferentes orientações, pelo viés do professor reflexivo e por meio do estudo de caso, foram estabelecidas três categorias de análise. Dos resultados, obtidos pela análise de dois questionários aplicados à 18 professores cursistas e de dois relatórios das professoras tutoras desse grupo, foi possível concluir que o curso foi importante pela retomada de conteúdos matemáticos, por abordar questões pertinentes ao trabalho em sala de aula, discutindo-as entre os pares e proporcionando alterações na prática pedagógica. Além disso, os professores cursistas consideraram que a participação de professores no programa Pró-Letramento em Matemática pode ser um dos motivos para a melhora no desempenho dos alunos na Prova Brasil, avaliação em larga escala para a Educação Básica. Esse programa, parceria do MEC-Ministério de Educação do Brasil com as Universidades parceiras e Sistemas de Ensino, aconteceu de 2005 a 2013.
