Abstract
The internet and technological advancements have revolutionized the way in which business and commerce is conducted nowadays. A lot has changed since the traditional over the counter form of trade to the electronic form of trade. The latter in which data is transferred electronically. E-businesses are beginning to examine the benefits of using Web 2.0, especially in the form of social networking sites, to collaborate with business partners and to communicate with consumers and potential employees. In order to create, possibly in the near future, a platform for selling services and typical Portuguese products, throughout this project various online companies' websites', which sell products and services, were analyzed. Other than analyze website characteristics we also tried to understand how these are sustained and how they interact with social networking services. © 2011 AISTI.

Abstract
Companies today live in a context of cycles in which there is an increasingly competitive and shorter life cycles for products and services, such as requiring a deep knowledge of customers and suppliers. The electronic business is one way to structure all the processes of the organization supported by Information and Communication Technologies (ICT) that allow a direct connection with customers, business partners, employees and its own management. This paper is a reflection on whether the e-business maturity models will fit the new reality of electronic business, in which the social networks are turning into a "social business". © 2011 AISTI.

Abstract
3D interface devices are being announced as rendering virtual world navigation easier. We have prepared a usability testing framework for two such devices, SpaceNavigator and SpacePilot PRO, manufactured by 3Dconnexion. The paper summarizes the underlying concepts of usability testing and links them to the requirements of a virtual world 3D interface context. We detail the metrics to be employed and the reasoning behind their selection, and the planning which yielded the actual framework to be used for conducting the 3D interface usability tests in the Second Life virtual world. © 2011 IEEE.

Abstract
Many military training centers still use traditional means to train and practice air traffic control. To represent reality, they use physical models of an airfield and aircrafts, or advanced computer simulations. LMS systems are also frequently used for management of online contents of courses. We are connecting simulations with LMS systems, in order to support trainers' tracking of trainees' progress. This paper presents a technological architecture that allows a trainee to use a virtual air traffic control (ATC) simulator to practice exercises available at the LMS and updates the LMS with the trainee's progress and actions within the simulator. It also presents details of a first approach to the implementation of this architecture. © 2011 IEEE.
