The information society is increasingly incorporating the immense volume of content available on the net. Access by electronic devices and the resulting ease of mobility and portability feed discussions on actual capacity of appropriation of this knowledge that circulates through cyberspace. Address and discuss the possibilities of educating across the network, therefore, gains more and more importance. On models of educational quality well developed – as is the case in Finland, for example-, Brazilian education is, year after year, failing in international marathons to achieve below average indexes required. Creates a field of analysis, in which this article arises, in the quest to understand more deeply the opportunity of use of Information and communication technologies (ICT) for a quality education, plunging by cultural issues that fall in the construction of objective conditions offered to students. This is an effort in understanding the historical factors that limit efforts to offering a quality education in Brazil.

The importance of the inclusion of digital technology in the classroom has already been pointed out by numerous authors in the educational field and some of them herald that it is through this inclusion that we can achieve transformations in school settings. Based on this assumption, this paper aims to present a distance learning course offered to in service and preservice teachers, focused on the use of technology in foreign language classroom primarily focusing on the role of teacher educators in mediating discussions. For this we sought theoretical support in studies which deal with distance courses (KENSKI, 2008), about virtual environments (ARAÚJO and MARQUESI, 2008), online discussion forums and investigation community and teaching presence (GARRISON, ANDERSON and ARCHER, 2000). Based on the previous theories presented, teacher educator’s messages were analyzed during a distance course offered to teachers in continuing and initial training, identifying marks of teaching presence and pointing to appropriate mediations and/or possible gaps. The results indicate that the teacher must be even more aware of the types of feedback that are provided and of the teaching presence mentioned by Garrison and colleagues (2000, 2001).

Amongst thematic networks, strategic laboratories and master and doctorate scholarships awarded by the National Program of Nanotechnology, an actor of great relevance can be distinguished due to its relative absence: the lay people, once more relegated to a secondary agent in Brazilian democracy, although citizens’ views have been increasingly recognized all over the world as an indispensable factor to the science and technology public policies which are intended to be democratic. Whereas Europe and United States have incorporated public values and feelings in the policy planning, Brazil is still waiting for opportunities of public participation in the definition of research guidelines. This paper examines contemporaneous demands of science communication to the strengthening of citizenship, aiming to offer contributions to a debate directed to question the present arrangement — of antidemocratic indifference towards the public — adopted in the formulation of public policies in Brazil.

This article aims to map the development of the market of digital TV in Brazil, under the aspect of the relation among culture, technology and politics. We start with a history of analog TV, since its inception, showing matrices of Brazilian TV. Then we try to show current conditions of the TV market in the country, its ambiguous relation with the internet and the possible ways for survival of open digital TV: respect for cultural diversity, the observation of the habits acquired from other media, the consistent use of digital language and the modifi cation of public policies in favor of the collective and not protectionism of large private communication companies.

This paper presents a study based on bibliographic research on LTE technology, chosen for the fourth generation of mobile phones, and the current status of implementation of 4G network in Brazil. The change in user behavior, which now uses data over the voice services, requires transmission networks to be increasingly robust and fast to enable the viewing of videos and use of other platforms that require internet connection. The retrospective of the development of mobile technologies, from 1G up to 4G that is currently used, shows the long road until it came to appliances and how the phone is used nowadays. Finally, the popularity of smartphones and hence the growing number of people with access to 4G networks, demanded new researchs for the development of future generations technologies in order to achieve the demand for speed enabling significant changes in user experience
