English in the digital age : Information and Communications Technology (ICT) and the teaching of English.

Muestra cómo la aplicación de las Tecnologías de la Información y de la Comunicación (TIC) mejoran la enseñanza y el aprendizaje de la lengua inglesa, enriquecen las habilidades de los alumnos e, introducen nuevos métodos educativos. Los estudios de varios colaboradores de Europa, Australia y América del Norte, consideran que tanto la utilización del material audiovisual tradicional: videos, películas, cintas de audio, cómo la de recursos más recientes: juegos de ordenador, recursos en línea, son materiales valiosos para la práctica educativa.

Interference and communications among active network applications

This paper focuses on active networks applications and in particular on the possible interactions among these applications. Active networking is a very promising research field which has been developed recently, and which poses several interesting challenges to network designers. A number of proposals for e±cient active network architectures are already to be found in the literature. However, how two or more active network applications may interact has not being investigated so far. In this work, we consider a number of applications that have been designed to exploit the main features of active networks and we discuss what are the main benefits that these applications may derive from them. Then, we introduce some forms of interaction including interference and communications among applications, and identify the components of an active network architecture that are needed to support these forms of interaction. We conclude by presenting a brief example of an active network application exploiting the concept of interaction.
