Today, information overload and the lack of systems that enable locating employees with the right knowledge or skills are common challenges that large organisations face. This makes knowledge workers to re-invent the wheel and have problems to retrieve information from both internal and external resources. In addition, information is dynamically changing and ownership of data is moving from corporations to the individuals. However, there is a set of web based tools that may cause a major progress in the way people collaborate and share their knowledge. This article aims to analyse the impact of ‘Web 2.0’ on organisational knowledge strategies. A comprehensive literature review was done to present the academic background followed by a review of current ‘Web 2.0’ technologies and assessment of their strengths and weaknesses. As the framework of this study is oriented to business applications, the characteristics of the involved segments and tools were reviewed from an organisational point of view. Moreover, the ‘Enterprise 2.0’ paradigm does not only imply tools but also changes the way people collaborate, the way the work is done (processes) and finally impacts on other technologies. Finally, gaps in the literature in this area are outlined.

Esta dissertação aborda directamente o conceito de sustentabilidade de um edifício numa vertente prática, ou seja, explica o que são sistemas de avaliação de sustentabilidade de ambientes construídos, aplicando um dos sistemas, o LiderA 2.0®, a um edifício já construído. Pretende-se com este trabalho final de mestrado, explicar a importância da construção sustentável nos dias correntes, e, principalmente, o modo através do qual se pode avaliar a sustentabilidade de uma construção. Desta forma, é feita uma abordagem sucinta a alguns dos sistemas internacionais de avaliação de sustentabilidade que existem actualmente, aprofundando particularmente o sistema português, LiderA 2.0®. Foi escolhido um edifício já construído, o edifício Ferreira Cardoso do Instituto Superior de Engenharia de Lisboa (ISEL) onde é ministrado o curso de Engenharia Civil, por se tratar de um edifício que, em termos de sustentabilidade ou falta da mesma, seria interessante de estudar, pois, este apresenta várias patologias a nível de consumo de recursos que devem de ser alteradas. Com a aplicação do sistema LiderA 2.0® ao edifício Ferreira Cardoso, obtevese a classe actual de desempenho ambiental. Todavia, foram propostas soluções que levaram a um aumento do desempenho ambiental do edifício, conseguindo por isso uma classe superior à actual. Após a realização deste trabalho, tendo em conta as oportunidades de melhoria propostas, bem como a possível aplicação das mesmas, espera-se que o mesmo seja expandido a outros edifícios do ISEL e, no futuro, a todo o campus.

The knowledge of the anisotropic properties beneath the Iberian Peninsula and Northern Morocco has been dramatically improved since late 2007 with the analysis of the data provided by the dense TopoIberia broadband seismic network, the increasing number of permanent stations operating in Morocco, Portugal and Spain, and the contribution of smaller scale/higher resolution experiments. Results from the two first TopoIberia deployments have evidenced a spectacular rotation of the fast polarization direction (FPD) along the Gibraltar Arc, interpreted as an evidence of mantle flow deflected around the high velocity slab beneath the Alboran Sea, and a rather uniform N100 degrees E FPD beneath the central Iberian Variscan Massif, consistent with global mantle flow models taking into account contributions of surface plate motion, density variations and net lithosphere rotation. The results from the last Iberarray deployment presented here, covering the northern part of the Iberian Peninsula, also show a rather uniform FPD orientation close to N100 degrees E, thus confirming the previous interpretation globally relating the anisotropic parameters to the LPO of mantle minerals generated by mantle flow at asthenospheric depths. However, the degree of anisotropy varies significantly, from delay time values of around 0.5 s beneath NW Iberia to values reaching 2.0 sin its NE comer. The anisotropic parameters retrieved from single events providing high quality data also show significant differences for stations located in the Variscan units of NW Iberia, suggesting that the region includes multiple anisotropic layers or complex anisotropy systems. These results allow to complete the map of the anisotropic properties of the westernmost Mediterranean region, which can now be considered as one of best constrained regions worldwide, with more than 300 sites investigated over an area extending from the Bay of Biscay to the Sahara platform.
