Title: Proposta de modelo conceptual de Data Warehouse para o Instituto Nacional de Estatística de Moçambique. Authors: Fijamo, Calado Pereira Abstract: O mercado atual é bastante competitivo, com constantes exigências em transformação de dados em informação e esta por sua vez em conhecimento. Uma informação clara e válida é o grande segredo de qualquer ramo de atividade, e é por isso que o conhecimento é a chave fundamental na tomada de decisão. O Data Warehouse desempenha um papel primordial como ferramenta de apoio na tomada de decisão, apresentando avanços substanciais comparativamente aos sistemas ou bases de dados tradicionais, oferecendo maior fiabilidade aos decisores estratégicos na sua difícil missão de tomar decisões rápidas e seguras. O instituto nacional de estatística de Moçambique, abreviadamente designado por INE-M, é o responsável pelas estatísticas oficiais do País, e detém um grande volume de dados de interesse nacional e internacional para produção de informação estatística. Estes dados, encontram-se armazenados e organizados em plataformas tradicionais, dificultando o acesso rápido e eficiente aos decisores quando pretendem tomar alguma decisão com segurança. Neste contexto, torna-se importante a existência de um repositório seguro e de acesso rápido, com capacidade de armazenar dados históricos da instituição. Este repositório facilitará aos dirigentes o cumprimento das suas obrigações e deveres de tomada de decisão, de forma eficaz e consistente. Um modelo conceptual de Data Warehouse que sirva de apoio estratégico na tomada de decisão será de certa forma a melhor e mais conceituada contribuição que o INE-M pode oferece aos seus utilizadores e parceiros, visto que, terão sempre resposta segura e em tempo útil.

Title: Studying the impact of co-authorship with external researchers:the case of research community in Portugal using social network analysis. Authors: Ferreira, Ana Sofia Gonçalves Abstract: Nowadays research institutions develop a significant amount of their activities financed by research grants and scholarships that sustain a constant human capital flow of temporary research labor. In this work and through the usage of Social Network Analysis we will study the impact of such policies in a Portuguese research institution. This evaluation will be applied to authorship data from papers published in international journals with refereeing covering the last twenty years of research activities involving permanent and temporary researchers from a Portuguese leading research institution in the field of telecommunications -­‐ Instituto de Telecomunicações (IT). This study compares the co-­‐authorship network and will reflect two main scenarios: a global perspective about this researchers network in terms of cohesion, and a detailed perspective about how the different subgroups are been interacting over time. Social Network Analysis will help us to understand how we can characterize their network behavior grouped by different scenarios as location, productivity and thematic groups. The paper will address the role of temporary researchers in network building and will determine the impact of their presence in this researchers network.

Title: ISEGI-NOVA AR Project - Augmented Reality Aplied to the Universidade Nova de Lisboa Authors: Cardoso, Pedro Miguel Vieira Abstract: In recent years, information technologies have progressed at an accelerated pace. The need to combine the availability of the information with portability has been fostering the evolution of technological devices, while producing some paradigm shifts. Nowadays, mobile computing, in particular, is an area increasingly put to use and recognised as necessary in terms of adding value to an information society. On that subject, the role of the more advanced generation of mobile phones, also called smartphones, has grown in terms of empowerment and importance. Evolving technologically day by day, smartphones can be presented as a communication tool that combines access to a key set of information and location services with pocket-like portability.At the same time, Augmented Reality – or the act of superimposing virtual elements to the image captured in real time – has been taking advantage of the rapid evolution in terms of the smartphones’ processing capabilities. The result has translated into the development of several technologies which make full use of wireless networks, of the capabilities for detecting positioning, and of the motion sensors. The current state of maturity of these technologies allows us to take Augmented Reality into account, not only as an innovative communication form for the mobile context, but also as a sophisticated method for exhibiting information while relating the presented object, through geo-referencing, with the real world.The goal of the ISEGI-NOVA AR Project consists in developing and deploying an Augmented Reality system that will assure a multitude of services, directed to the smartphone medium. These services will allow users to interact with multimedia layers (images, sounds, video, text, animations) superimposed, through geo-referencing, to the image captured by the smartphone camera. Besides the ability to provide Augmented Reality contents, another project goal is to develop a web platform that allows dynamic Augmented Reality content creation, through graphical user interfaces. The report includes a technology selection phase, architecture overviews, and the description of all of the developed software components. The outcome of the ISEGI-NOVA AR Project will deliver new tools to the Universidade Nova de Lisboa, to be used for information publishing and will represent, ultimately, a new era in terms of the relationship between the university and the community.

Title: Dynamics of innovation patterns: some insights for Portugal Authors: Martins, Ana Isabel Magalhães Abstract: Innovation has increased its importance in the past few years in several areas, calling the attention of many sectors of our society due the key role that innovation has in firm's life, namely in determining its competitiveness and sustainability (Freire, 2006). Consequently, innovation is also crucial to the economic growth of a country (Bilbao-Osorio and Rodríguez-Pose, 2004). The aim of this work is to identify and characterize Portuguese firms innovation patterns using CIS3 (1998-2000) and CIS4 (2002-2004) data for both manufacturing and service sectors and to compare the results between them. Through a Cluster Analysis we identify and define three clusters in each sector for each period of time. The results show that there are differences between sectors and that some changes occurred through time, namely those related to innovation objectives and sources of information. We conclude that innovative pattern of firms in service sector in period 2002-2004 is significantly different from the innovative pattern of manufacturing and service sector firms in 1998-2000. Comparing our results for CIS3 and service sector with those obtained for Spain and published by Camacho and Rodriguez (2008), we conclude that there are differences in the strategies of the innovation activities and in the distribution of innovation expenditures between the two countries and similarities in what concern with the main innovation objectives and sources of information. The two countries also differ in the way firms of different industries innovate; in service sector, in 1998-2000, while Spanish firm’s innovative behaviour was heterogeneous within industries, in Portugal the firm’s behaviour was homogeneous.
