Abstract
In this paper, we propose an architecture based on three layers (infrastructure, server hardware and operating system, and business applications) for a unified communications solutions exclusively sustained on open source technologies and open standards. Additionally, we discuss the importance of open standards and open source in a fully integrated communications solution, exposing some factors that a company should consider when choosing open source software.

Abstract
Internet Banking has emerged as one of the most remarkable and profitable ecommerce applications over the last decade. The home banking is a service that allows new ways of interaction with customers, turning possible to overcome the barriers of distance between bank institutions and their clients. Despite the increasing importance of home banking, very few studies were made in the Portuguese context and, therefore, very little are known about the profile of users of this service particularly in some specific domains. This paper has the objective to show the results of our study considering the use of Internet Banking among Portuguese college students contextualized with other existing studies/publications and performing a critical analysis from the obtained results. We realized that the large majority of students use Internet Banking, consider the service safe, adopt it essentially for money movements and have a strong perception that bank institutions adopts anti-frauds mechanisms. Additionally, our study demonstrated that there is a strong association between the simultaneously use of home banking and MBNet services, and we realized that the user perception about the safety of Internet Banking increases with the use of these services. © Filipe Moreira, Pedro Rocha and Fernando Almeida, 2012.

Abstract
Universities are continually pursuing ways to adapt their educational practices, looking to develop new learning culture that encourages creativity and active engagement. The adoption of augmented lecture podcast scenarios, based on a content-centric paradigm, looks a promising way to reach a new level of interactivity. This paper analyzes the main advantages provided by this innovative approach comparing it with the traditional podcasting developing model. Additionally, it proposes possible business models based on content distribution and augmentation, to enable wider exploitation of the approach within university environments. © 2012 Infonomics Society.

Abstract
The empirical studies in the area of Open Innovation (OI) reveal that there is a significant bias in favour of countries on the technological frontier. The present study aims to bridge this gap by examining firms in Portugal, a country at an intermediate stage of technological development. Based on 70 innovative firms, we found that whatever perspective of the OI model is considered, firms tend, on average, to share a relatively closed innovation model when compared with firms located in countries where technological development is advanced. About a quarter of the surveyed firms implemented the OI model in their innovation strategy/business, this being much more widely disseminated regarding the absorption of external knowledge/technology, with almost 40% of firms surveyed acknowledging its use in comparison with the perspective of transfer of knowledge/technology to other organisations - less than 10% provide their "surplus technology" to other organisations. This result may indicate a lack of awareness of the economic potential of making internally created technologies available to third parties, albeit this potential might also depend on other circumstances such as technology architecture (the system and interdependence of technologies).
