Joining the online video conversation? Discourse and practices of European political institutions and politicians on YouTube

To mimic the online practices of citizens has been declared an imperative to improve communication and extend participation. This paper seeks to contribute to the understanding of how European discourses praising online video as a communication tool have been translated into actual practices by politicians, governments and organisations. By contrasting official documents with YouTube activity, it is argued that new opportunities for European political communication are far from being fully embraced, much akin to the early years of websites. The main choice has been to use YouTube channels fundamentally for distribution and archiving, thus neglecting its social media features. The disabling of comments by many heads of state and prime ministers - and, in 2010, the European Commission - indicates such an attitude. The few attempts made to foster citizen engagement, in particular during elections, have had limited success, given low participation numbers and lack of argument exchange.

A celebração do casamento do Príncipe Carlos com Camilla Parker Bowles: mediação e mediatização

Tendo presente a relação que o discurso estabelece com a sociedade como um todo, este artigo procura analisar o modo como a monarquia britânica representou o segundo casamento do Príncipe Carlos e o modo como os media construíram os relatos do acontecimento desde 10 de Fevereiro a 9 de Abril de 2005 relativamente a assuntos mais vastos, como sejam as relações de poder, as estruturas económicas dos jornais e a cultura popular. Foi dada particular relevância aos aspectos multifuncionais do discurso (por exemplo, as funções ideacional, interpessoal e textual), o que requer uma leitura contextualizada de um duplo processo de mediação: por um lado, a organização da cerimónia levada a cabo pelo Palácio de St. James e a sua subsequente estratégia para atingir um fechamento monológico e, por outro, as representações discursivas da imprensa britânica, abertas a uma polifonia de vozes e a vários enquadramentos discursivos.

The wedding of Prince Charles and Camilla Parker-Bowles: royal mediation and press mediatization

Bearing in mind the relationship between discourse and society at large, this article addresses the way the British monarchy represented Charles’s second marriage and the way the media constructed their accounts in the period from 10 February (announcement) until 9 April 2005 (wedding) in relation to wider issues such as power relations, newspaper economic structures and popular culture. Particular attention is paid to the multifunctional features of discourse (i.e. its ideational, interpersonal and textual functions), which requires a contextualized reading of a dual process of mediation: on the one hand, the staging of the ceremony by St. James’s Palace and its strategy for attaining monologic closure and, on the other hand, discursive representations by the British press open to a polyphony of voices and discursive frames

Technical and economic assessment of energy from Tidal Currents

The present work aims to study the feasibility of deploying a farm of sea current turbines for electricity generation in Portugal. An approach to the tides, which are they, how they are formed, its prediction, is held. It is also conducted a study about the energy of sea currents and it is presented some technology about ocean currents too. A model of tidal height and velocity of the currents it is also developed. The energy produced by a hypothetical park, built in Sines (Portugal), is calculated and afterwards, an economical assessment is performed for two possible scenarios and a sensitivity analysis of NVP (Net Present Value) and LCOE (Levelized Cost of Energy) is figured. The conclusions about the feasibility of the projects are also presented. Despite being desired due to its predictability, this energy source is not yet economically viable as it is in an initial state of development. To push investment in this technology a feed-in tariff of, at least €200/MWh, should be considered.
