This paper aims at discussing the characteristics of computer mediated language within a foreign language teaching and learning environment enabled by the use of synchronic writing resources – chat. The present research is based on (i) theoretical principles about the use of technologies and the teaching-learning of foreign languages in the scope of the Teletandem Brazil Project: Foreign languages for all – Projeto Teletandem Brasil: línguas estrangeiras para todos (TELLES, 2005); (ii) studies on the characteristics of the language within chat interactions; (iii) different theoretical perspectives on the relationship between spoken and written language, emphasizing the constitutive heterogeneity of writing perspective (CORRÊA, 1997, 1998, 2001); and (iv) some relevant concepts related to Prosodic Phonology field (NESPOR; VOGEL, 1986). Is being taken as research data, the written production of a Brazilian student (finishing a Licentiate in Literature) interacting with an American student (in Religious Studies) through Windows Live Messenger. The data were collected during a five-month period, during which the participants interacted through chat, totalizing 12 interactions in English and in Portuguese. During the analysis, a particular attention was given to the messages’ fragmentation, the use (or not) of punctuation signs and abbreviations within the Brazilian participant’s production, in order to discuss the representations she built of her writing, her interlocutor, herself and on the teaching-learning process of a foreign language.

This article proposes a method for 3D road extraction from a stereopair of aerial images. The dynamic programming (DP) algorithm is used to carry out the optimization process in the object-space, instead of usually doing it in the image-space such as the DP traditional methodologies. This means that road centerlines are directly traced in the object-space, implying that a mathematical relationship is necessary to connect road points in object and image-space. This allows the integration of radiometric information from images into the associate mathematical road model. As the approach depends on an initial approximation of each road, it is necessary a few seed points to coarsely describe the road. Usually, the proposed method allows good results to be obtained, but large anomalies along the road can disturb its performance. Therefore, the method can be used for practical application, although it is expected some kind of local manual edition of the extracted road centerline.

The purpose of this paper is to introduce a methodology for semi-automatic road extraction from aerial digital image pairs by using dynamic programming and epipolar geometry. The method uses both images from where each road feature pair is extracted. The operator identifies the corresponding road featuresand s/he selects sparse seed points along them. After all road pairs have been extracted, epipolar geometry is applied to determine the automatic point-to-point correspondence between each correspondent feature. Finally, each correspondent road pair is georeferenced by photogrammetric intersection. Experiments were made with rural aerial images. The results led to the conclusion that the methodology is robust and efficient, even in the presence of shadows of trees and buildings or other irregularities.

Information flows are formed naturally or formally induced in organizational settings, passing from the strategic level to operational level, reflecting, and impacting in the processes that make up the organization, including the decision-making process and therefore the action strategies of organization. The management of organizational environments based on information requires careful attention to various kinds of languages used for communication between sectors and employees of the organization, whose goal is to share, disseminate and socialize the information produced in this environment.

The relation among the concepts text, document and information is discussed, with the aim of clarifying the concept of document, with a focus in the field of economic information organization and management. A document is a medium in which information is recorded and manifested. A document is, thus, material, has a purpose, can be organized and treated for its improved dissemination, and has a specific subject and context.

Este artigo tem o objetivo de repensar conceitos, conteúdos e objetivos de temáticas ligadas à área de História através da articulação entre o uso de linguagens audiovisuais – no caso, o cinema – o papel da narrativa e a construção de práticas de ensino, todas baseadas nos estudos de micro-história. Desejamos não apenas debater os potenciais pedagógicos e empíricos dos recursos tecnológicos dentro das salas de aula, mas, especialmente, o das possibilidades reais de transformação dos alunos em sujeitos do processo de construção de novos conhecimentos na área, por meio da produção do curta metragem. Essa ferramenta pedagógica e tecnológica pode ajudar-nos a refletir sobre as prerrogativas dos PCN’s que prevem em suas propostas a valorização do local e do cotidiano dos alunos, o respeito à diversidade e pluralidade, o papel dos sujeitos na História. A proposta aqui apresentada é fruto de um projeto realizado na Fundação Educacional de Fernandópolis entre 2009 e 2010, sob a forma de trabalhos de conclusão de curso desenvolvidos por alunos do curso de graduação em História.
