Multiplicação e convergência das mídias: desafios para a educação física escolar

This article presents pedagogical reflections on the relationship between media and physical education, a scenario in which digital technologies facilitate and expand access to media. Then there is the need to approach physical education to the media, given its importance in symbolic representation and behavior of students within the movement body culture. The primary intentions of the media are not necessarily compatible with the purposes of school. This apparent contradiction leads us to wonder, in dialogue with the area of media education, which would be the potential of media as a strategy for pedagogical action.

Modelagem Matemática e Análise de Modelos Matemáticos na Educação Matemática

In this paper we present two studies, the first one completed and the second one in development, which are based in teaching approaches that propose the qualitative study of mathematical models as a strategy for the teaching and learning of mathematical concepts. These teaching approaches focus on subjects from Higher Education such as Introduction to Ordinary Differential Equations and Topics of Differential and Integral Calculus. We denominate this common aspect of the teaching approaches as Model Analysis and in a preliminary level we relate it with Mathematical Modeling. Furthermore, we discuss some questions related with the choice of the theme and the role of Digital Technologies when Model Analysis is applied.

Comunicação midiática e educação na cibercultura

This article aims to discuss how communication can contribute effectively with education in cyberculture, by design of educational environments that are configured according to the specific language of cyberspace. We consider digital technologies as language and therefore as forms of communication. As a theoretical basis, we use Peircean semiotics, for questions relating to language; the concept of technologies of intelligence, to the relation of the technique with digital media and the concepts of emergency and of transmiting architecture to think of cyberspace communication interfaces. We made a brief reflection on the political, administrative, social, cultural and economic problems that hinder the development of more appropriate forms of education for cyberculture. Then we point out some similarities between the fields of education and communication and made some observations about qualities of digital media that can contribute to a mbetter use of it as an educational tool. Finally, we indicate an educational and communicational gaming approach as a possible way to make communication technologies interactive audiovisual interfaces, able to educate in the age of cyberculture.

Videoclipe em ambiente de convergência midiática: regimes de sentido e interação

The article discusses the changes in the relations between communi- cation and forms of consumption of the video formats guided by new interactive content and enabled by the digital technologies of contemporary medias. In light of sociosemiotics by Eric Landowski, regimes of meaning and interaction in the fruition process present in the music video The Time/Dirty Bit, of Black Eyed Peas, and the respective application for mobile devices BEP 360 are discussed.

Introduction to the Software-defined Radio Approach

Telecommunications have been in constant evolution during past decades. Among the technological innovations, the use of digital technologies is very relevant. Digital communication systems have proven their efficiency and brought a new element in the chain of signal transmitting and receiving, the digital processor. This device offers to new radio equipments the flexibility of a programmable system. Nowadays, the behavior of a communication system can be modified by simply changing its software. This gave rising to a new radio model called Software Defined Radio (or Software-Defined Radio - SDR). In this new model, one moves to the software the task to set radio behavior, leaving to hardware only the implementation of RF front-end. Thus, the radio is no longer static, defined by their circuits and becomes a dynamic element, which may change their operating characteristics, such as bandwidth, modulation, coding rate, even modified during runtime according to software configuration. This article aims to present the use of GNU Radio software, an open-source solution for SDR specific applications, as a tool for development configurable digital radio.

Comentários gráficos sobre os desenhos de Paulo Mendes da Rocha

Partindo-se do pressuposto de que o desenho é instrumento de diálogo entre o arquiteto e ele mesmo ou com terceiros e que este tipo de representação vem perdendo espaço para tecnologias digitais, este trabalho tem como objetivo estudar e analisar desenhos de projetos selecionados do arquiteto Paulo Mendes da Rocha, como contribuição para a discussão sobre o papel do desenho analógico no processo projetivo atual. O estudo acerca de quatro projetos (Ginásio do Clube Paulistano, Residência Butantã, Residência Millan e MuBE) se deu através de marcações realizadas pela pesquisadora sobre desenhos originais do arquiteto, com o objetivo de detectar intenções projetuais, conceitos e características dos projetos. Para tanto, foram feitas marcações gráficas sobre os desenhos originais, de maneira a evidenciar uma leitura particular da pesquisadora, permitindo assim uma melhor compreensão dos projetos escolhidos para o estudo. O desenho sobre o desenho marca os pontos que o julgamento considera importantes, tratando-se de uma leitura particular e permitindo melhor compreensão dos projetos para quem o pratica, uma vez que o ato de desenhar está estreitamente relacionado ao de pensar. Optou-se por apresentar as imagens relacionadas a citações diretas de autores

Creative process in globally distributed teams: a study of new product development in Volvo

With the business environments no longer confined to geographical borders, the new wave of digital technologies has given organizations an enormous opportunity to bring together their distributed workforce and develop the ability to work together despite being apart (Prasad & Akhilesh, 2002). resupposing creativity to be a social process, the way that this phenomenon occurs when the configuration of the team is substantially modified will be questioned. Very little is known about the impact of interpersonal relationships in the creativity (Kurtzberg & Amabile, 2001). In order to analyse the ways in which the creative process may be developed, we ought to be taken into consideration the fact that participants are dealing with a quite an atypical situation. Firstly, in these cases socialization takes place amongst individuals belonging to a geographically dispersed workplace, where interpersonal relationships are mediated by the computer, and where trust must be developed among persons who have never met one another. Participants not only have multiple addresses and locations, but above all different nationalities, and different cultures, attitudes, thoughts, and working patterns, and languages. Therefore, the central research question of this thesis is as follows: “How does the creative process unfold in globally distributed teams?” With a qualitative approach, we used the case study of the Business Unit of Volvo 3P, an arm of Volvo Group. Throughout this research, we interviewed seven teams engaged in the development of a new product in the chassis and cab areas, for the brands Volvo and Renault Trucks, teams that were geographically distributed in Brazil, Sweden, France and India. Our research suggests that corporate values, alongside with intrinsic motivation and task which lay down the necessary foundations for the development of the creative process in GDT.
