Abstract

As the present world increase its complexity and speed in a society filled with information, it seems necessary to imagine the future. And media education must be included in this reflection because it is important to understand that complexity and that speed at the present as well as in the future, especially if we really want to rule our lives. This is the aim of this paper: to know the two basic pillars of audiovisual communication: digital television and the Internet, trying to deduce the values involved in this process in order to use some of them as a reference to renew the media education.

Abstract

The Internet as a socio-telematic media should generate and increase educational processes. Teaching and reading practice in the Internet is very necessary in order to learn to interact critically. The development of skills to explote its potencial for a deep and thoughtful comprehension with the transference to other reading situations, interaction and navigation will help for an autonomous and imaginative person.

Abstract

This paper explores the new ways of relation and interaction which are taking place into the lnformation Society, particularly on the use of the latest information and communication technologies (ICTs). Young people, the «Net generationn, have a very good opinion of the language of links. They are taking the most of the relation and communication potentials from the new technologies such as the Internet. These present changes mean chances and risks that should be taken into account by teachers and communicators.

Abstract

The virtual school es neither restricted to a physical place (the school) nor a fiexed timetable. On the wntrary, students and teachen interact without spacial or temporary restriaions. Virtual school provide big opportunities to the students who cannot attend regular classes for different reasons and in some cases technolow turns out to be a more successful model than wnventional education.

Abstract

Internet Relay Chat (IRC) is a virtual meeting point where people from al1 over the world can meet and talk. On context new strategies for creating shared systems of significance, and strategies for constructing an identity, have evolved. These strategies consist mostly of linguistic resources, since the access to visual or auditory features such as appearance or accent, which are significant identiwcreating factors in face-to-face interaction, is quite limited. In this paper, and following the theoretical framework of social constructivism, it is analyzed how chat participants may develop and sustain an identity in IRC chatrooms by using several linguistic and/or graphic resources on the web.

Abstract

Part 1: Autonomic and Decentralized Management International audience Energy efficiency has become a major research topic in the Internet community as a result of unprecedented rise in the Information and Communication Technology (ICT) sector. One typical approach towards energy efficiency is to select a subset of IP routers or interfaces that will go to sleep mode during the off-peak period. However, on-the-fly network reconfiguration is generally deemed harmful especially to real time packets due to routing re-convergence. In this paper, we develop an efficient algorithm for achieving energy efficiency which is disruption free. The objective is to incrementally wake up sleeping links upon the detection of increased traffic demand. Unlike normal approaches of manipulating link weights or reverting to full topology in case of even minor network congestion and thereby sacrificing energy savings, our algorithm wakes up the minimum number of sleeping links to the network in order to handle this dynamicity. The performance of our algorithm was evaluated using the GEANT network topology and its traffic traces over a period of one week. According to our simulation results, up to almost 47% energy gains can be achieved without any obstruction to the network performance. Secondly, we show that the activation of a small number of sleeping links is still sufficient to cope with the observed traffic surge. Document type: Part of book or chapter of book
