Radio broadcasting in Spain is still analog and DAB is awaiting its opportunity. Without an audience or receivers, Spanish free-to-air digital radio is inconsequential, merely anecdotal, although the European context is changing and some countries have been investing more in this distribution platform in recent years. This article aims to answer the question why DAB in Spain does not have anyone willing to bring it back to the forefront. To do so, we use the idea of the “window of opportunity” and, along with path-dependence, we place it in the theoretical framework of the main constructivist approaches. [ABSTRACT FROM AUTHOR]

This paper shows the results of a survey performed in Spain on the different functionalities of e-learning platforms. This survey was filled in by a group of teachers, experts in engineering education from across Spain, within the scope of the Spanish Chapter of the IEEE Education Society. This paper presents their opinions on several aspects of e-learning functionalities, such as knowledge levels, levels of use, and usefulness, as well as describing the most commonly used platforms. One of the objectives of this work is to create a debate in the international community about the use of e-learning platforms and their main functionalities, the most frequently used standards, the implications for and the levels of support by institutions in their use of e-learning platforms, and in general, their advantages and disadvantages.

It does not seem too risky or bold—at the start of the new century—to assert that digital radio has an uncertain future. The present article analyzes the causes of the failure of DAB (Digital Audio Broadcasting) in Spain using particular current and historical features of the Spanish radio industry to do so (note that Spanish radio falls halfway between the North American commercial model and the European public service model). The opinions of different telecommunications experts, comparisons with other European countries, as well as the defining characteristics of the standard chosen, Eureka 147, better known as DAB, are presented.
