L'oeuvre de Moscovici se résume à une tentative de rapprochement du psychique et du social, ne serait-ce que parce que la rationalité et l'irrationalité sont transversales auz comportaments individuels et à l'activité sociale. En ce sens, l'individu n'est pas plus du ressort de la seule psychologie que la societé ne l'est de la seule sociologie. Simplifier la realité reviendrait à simplifier la connossaince de celle-ci. La psycho-sociologie de Moscovici nous invite donc à prendre en compte l'homme dans sa complétude, en tant que mixte de logique et de sentiments, de raison et de passions. On comprendra alors l'importance du paradigme écologique dans les sciences sociales comme forme de compréhension de ce qui relie l'homme à une entité plus vaste, le renvoyant aussi bien à la nature et à son ascendance animale qu'à la techinque et à sa destinée post-humaine.

This paper presents an on-board bidirectional battery charger for Electric Vehicles (EVs), which operates in three different modes: Grid-to- Vehicle (G2V), Vehicle-to-Grid (V2G), and Vehicle-to-Home (V2H). Through these three operation modes, using bidirectional communications based on Information and Communication Technologies (ICT), it will be possible to exchange data between the EV driver and the future smart grids. This collaboration with the smart grids will strengthen the collective awareness systems, contributing to solve and organize issues related with energy resources and power grids. This paper presents the preliminary studies that results from a PhD work related with bidirectional battery chargers for EVs. Thus, in this paper is described the topology of the on-board bidirectional battery charger and the control algorithms for the three operation modes. To validate the topology it was developed a laboratory prototype, and were obtained experimental results for the three operation modes.

Os modos de fazer pesquisa científica têm vindo a alterar-se, em função das mudanças pelas quais passa o Ensino Superior, assim como os sistemas de ciência e tecnologia, no seu todo. Na Europa vivem-se tempos de grandes questionamentos acerca do modo de proceder relativamente à definição de metodologias de avaliação e/ou financiamento público à investigação individual e/ou coletiva. A tendência geral, neste contexto, é para aperfeiçoar as metodologias de avaliação, através da definição de indicadores que permitam medir as várias dimensões do trabalho científico. No campo específico da avaliação, prevê-se cada vez mais a avaliação do impacto das pesquisas. Ocorre que, apesar do número e da amplitude dos indicadores que vão sendo propostos, a definição de impacto resulta numa tarefa difícil. Não só porque a realidade medida nem toda é perfeitamente traduzível em algo tangível, mas também porque existem diferenças significativas nos modos como as diferentes áreas produzem conhecimento. Neste artigo, pretende-se refletir sobre esse conceito de impacto, nomeadamente ao nível das ciências sociais, evidenciando aquelas que são as principais conclusões e reflexões de estudos e escritos mais recentes.

Despite improvements over the years, accidents continue to be a scourge in the construction sector, leading to an increase in the number of journal articles addressing the issue, in an attempt to help construction industry to increase safety performance [1]. This paper aims to, helping construction industry and particulary tunneling community, describe the Portuguese approach to most typical health and safety problems in underground excavations performed with the Sequential Excavation Method (SEM). The article will address various topics, from safety management and organizational practices, to collective and personal protection equipment, to emergency planning. nt problems in safety and health matters are similar to several other countries, the paper will expose a compilation of Portuguese best practices used to solve that problems. This enunciation of best practices describes experience from most important and recognized Project Owners and Contractors in Portugal. In a second phase it will be analysed Portuguese weaknesses, identifying preventive measures, and their comparative importance, that should be adopted in Portugal in order to reduce accidents and health diseases.

Gender ideologies in Cape Verde are shifting. Individuals find themselves caught between changing tides, pushed and pulled in opposite directions by divergent gendered expectations. The article examines the different ways in which young women and men take recourse to tactics in response to the tensions that arise as they deal with changing gender ascriptions in the midst of their relations with community and kin. Women, in particular, are unevenly affected by traditional demands and expectations whilst they cross the boundaries of traditional gender roles in their pursuit of enhanced education and more sexual freedom. Yet, their actions are not characterized by an outright rejection of traditional gender ideologies, but rather by piecemeal tactical manoeuvres to plot a route through the centrifugal forces at play. keywords

Novel input modalities such as touch, tangibles or gestures try to exploit human's innate skills rather than imposing new learning processes. However, despite the recent boom of different natural interaction paradigms, it hasn't been systematically evaluated how these interfaces influence a user's performance or whether each interface could be more or less appropriate when it comes to: 1) different age groups; and 2) different basic operations, as data selection, insertion or manipulation. This work presents the first step of an exploratory evaluation about whether or not the users' performance is indeed influenced by the different interfaces. The key point is to understand how different interaction paradigms affect specific target-audiences (children, adults and older adults) when dealing with a selection task. 60 participants took part in this study to assess how different interfaces may influence the interaction of specific groups of users with regard to their age. Four input modalities were used to perform a selection task and the methodology was based on usability testing (speed, accuracy and user preference). The study suggests a statistically significant difference between mean selection times for each group of users, and also raises new issues regarding the “old” mouse input versus the “new” input modalities.

A regulação dos media tem ganho relevo nas agendas nacionais e internacionais mas nem sempre a utilização corrente do conceito é consistente, correndo o risco de significar tudo e nada em simultâneo. Independentemente do intenso e profícuo debate concetual que o tema suscita na comunidade académica, julgamos pertinente o estudo das estruturas de regulação mediática que operam no terreno da União Europeia. Este trabalho reflete sobre as entidades de regulação mediática que atuam na defesa do interesse público, ainda que existam as mais diversas modalidades de enunciação e de defesa desse interesse pelos vários estados, e decorre de um esforço de investigação coletivo, enquadrado no projeto “Regulação dos Media em Portugal: O Caso da ERC”, que agregou elementos sobre os organismos reguladores dos media na Europa.
