Abstract
Besides services traditionally available in wireless networks, new ones may be offered that transparently adjust and adapt to the user context. The user would have more choice and flexibility if not only could he use platform and third-party services, but also compose his own services in an ad-hoc way, making it available to other users, involving them collaboratively in the construction of a wide set of services. Moreover, collaboration among users can be fostered by the availability of awareness services in mobile environments that enable them to execute joint tasks and activities. This paper presents iCas, an architecture to create context-aware services on the fly, and discusses its main modules. Also a collaborative application scenario is briefly described.

Abstract
The production of scientific publications requires usually the participation of several authors that contribute to the final result according to their role in the work being described. Nevertheless, this is obviously a cooperative activity and requires the simultaneous presence of the collaborators or the exchange of documents and annotations through email. Cooperative editors introduced a further step in the cooperation, but the current solutions do not accommodate issues like referencing and publishing. This gap motivated us to build a platform that integrates the three main functionalities required to effectively produce scientific publications: a cooperative text editor, a cooperative reference manager and a connector to scientific digital repositories. This paper presents this solution, which we called PaperFlow and was specified with the aid of a study conducted with Portuguese and Spanish researchers, which results are also presented, with the aim of evaluating the platform requirements.

Abstract
The last decade brought about several virtual communities spread all over the world composed of thousands of people with different ages and social, cultural and physical characteristics. These communities enable users to communicate and share information, often with the aim of achieving a common goal. Due to the vast diversity of users there's often a need,to control the activities that occur inside the virtual environment to avoid inappropriate behaviors. However, this control can cause a feeling of digital surveillance, but an appropriate design of the interface can help minimize its impact, becoming an important success factor for the community. For this purpose we analyzed a selection of virtual environments, conducted a survey on users' preferences and analyzed the corresponding results. From these activities we defined a set of requirements to build a 3D interface for a regulated virtual environment.

Abstract
A Social Networking System was developed for Academic Collaboration across international Projects. The system was implemented using Java Server Pages. This paper discusses the development of this software, lessons learned and it gives suggestions for further work.

Abstract
Writing scientific publications is usually a challenging and complex activity, involving several authors. Despite the different natures of their contributions, this activity is clearly collaborative and the collaboration is usually achieved through face-to-face meetings and using email to exchange the documents. More recently the availability of collaborative editors introduced a further step in the collaboration, but none of the existing solutions contemplate some specific issues like referencing and publishing adequately. This fact motivated us to conduct a study to evaluate the requirements for a platform that integrates in a single solution the three main functionalities required: a text editor, a reference manager and a connector to scientific digital repositories.

Abstract
Serious games are playing an increasing role as educational tools and the last decade witnessed a growing number of proposals in this field. One of the major challenges of the current European societies is to foster an entrepreneurial interest in young people, and the European Commission has been promoting projects that pursue this objective. This chapter presents one such project, PLAYER, in which an educational game was implemented in Facebook with the aim of promoting entrepreneurship by guiding young people in the definition of a business proposal. The game encompasses 4 stages that include the basic description of the business idea, the characterization of its strategies, the filling of a funding quiz, the SWOT analysis, and finally the production of a detailed business plan, for those players to be able to reach the final stage of the game. © 2012, IGI Global.
