Abstract
The Internet is extremely important for the publishing of information and for the interaction between the society elements. Due to this, it's essential that the web presents itself accessible to all, including those with any kind of disability. An accessible web may help the handicapped citizens interact with the society in a more active way, including the electronic public procurement platforms. This paper presents a study made with a universe of 8 Portuguese certified platforms (by CEGER), using a W3C referenced tool (TotalValidator), and presents some statistical results according to the Portuguese Classification of the Enterprises Activities.

Abstract
The Second Life platform unites various technologies: 3D virtual environments, virtual reality, Internet connection between participants and the possibility of customization of the three-dimensional content. It is a virtual collaborative environment that allows users to explore digital worlds and interact with others in real time. Increasingly, new peripherals to interact with virtual environments are emerging in the market, and good examples of this are 3Dconnexion's 3D controllers. These are designed to be easy to use, allowing users to zoom, move around in space and rotate 3D objects with a simple hand tap on the device. With this project we wanted to identify usability problems among 3Dconnexion's devices in Second Life 3D virtual environment. We created a usability test and implemented it. With its data we identified usability features of these 3D controllers.

Abstract
Companies that are present at multiple online locations may have difficulty staffing them adequately in terms of helpdesk services with efficient use of human resources. In this paper a technological architecture is presented that allows a team of people to staff several online locations simultaneously, providing to customers/users the indication of human presence to attend them. We also present details on a first prototype implementation of this architecture.

Abstract
In a dynamic and competitive world, understanding the knowledge, skills and competences that managers of small and medium enterprises (SMEs) require is an important endeavour, to ensure that both academic and business training institutions offer well formed programs/courses and curricula. Several studies, conducted by academic researchers and business associations around the world, focused on identifying managers' skills and competences, but there isn't an overall perspective on today's requirements of European SME managers. This is a critical aspect because managers' competences strongly influence enterprises' competitiveness and, therefore, the economic competitiveness of countries themselves. To help overcome this problem, the authors conducted a study in six European countries through a literature review and several interviews with business associations' executives. The result is a list of 34 competences, which the authors organized in four categories: personal; team management; business; and technical. These competences are presented and discussed in this chapterand show that an SME manager should be well prepared in a rich set of complementary areas to perform her/his job. The findings enable a better understanding of the profile of SME managers from the point of view of required competences, and may help in the design of new training programs to fulfil the identified needs. © 2011, IGI Global.

Abstract
The requirements of an increasing globalized and competitive economy lead managers to search for training solutions which can rapidly bridge the gap of their lacking skills, knowledge or competences. To assert with adequate training programs, in particular for SMEs managers, a study was conducted in six European countries with the objective of identifying the most relevant competences they need to fulfill. A literature review and several interviews with business associations' executives resulted in a list of 34 competences which were organized in four categories: personal, team management, business and technical. These competencies were put at trial through a survey conducted among 154 SMEs managers who had to evaluate each proposed competence with the attribution of a relevance degree. Although we show that SME managers should be well prepared in a rich set of complementary areas to perform their job, it is clear that some of the competences are crucial for them to tackle today's challenges. This paper presents a ranking of the competences by importance as perceived by managers. These findings can help training institutions wishing to design new training programs which more in line with managers' needs.

Abstract
While much information is available on pedagogic uses of virtual worlds, with Second Life being the most common virtual world platform in current educational literature, an organization must consider its presence in this environment as more than the mere sum of individual educational efforts. Resources need to be shared between educational stakeholders, visual navigation needs to make sense, and the sense of being within an actual organization should be conveyed (not just the sense of being within a collection of personal spaces). But there is little information on how a virtual campus for an educational organization should be structured. Virtual campi in Second Life for adult education institutions don't typically reproduce their physical counterparts. While spaces such as lecture halls, amphitheatres, meeting places, and libraries are commonly found, the specific features of the medium imply an organization of spaces and usage that differ from physical campi. For instance, navigational affordances are different (ability to fly and gravity-immune objects, for instance), as are communicational features (specific limits on the reach of voice and text communication), and user involvement (how students and teachers use the spaces). We conducted a survey of several existing Second Life campi of adult education institutions (mostly universities), to establish what spaces are present in each and how they are used and organized. In this paper, we present the overall process, and the structure and instructions for data collection by all people involved. Then we detail the various kinds of spaces (by function, not by aesthetic) found in the campi and their prevalence. We also present data on user-oriented features of the campi, and cross-analyse this with their occurrence per space and campi. This survey was part of the process for specification and development of the virtual Second Life campus for project VITA, a EC-funded project to create and experiment learning actions directed to SME' managers for development of entrepreneurship competences. Thus, we conclude with an example of how the survey results can be used to support the development of campi, by briefly presenting the campus that was developed specifically for this project.
