New emerging technologies create a distributed environment where devices, sensors and wired and wireless networks become invisible and humans come to the foreground. User information is being collected, processed and shared. The Ambient Intelligence (AmI) world is a computing environment functioning in an ubiquitous manner, combining data from a diverse set of resources and monitoring user health, preferences, security and movement in an interactive and user-friendly way. This networked intelligence, which is based on intensive user profiling, is increasing concerns on the preservation of human privacy. In this work, we identify the characteristics of AmI spaces and their implications on users' privacy. We examine the regulatory privacy framework in the European Union (EU) and identify the existing inefficiencies to cope with the new challenges of AmI spaces. We discuss the issues that need to be addressed during the design, implementation and adoption of such services. We argue that AmI technology adoption has to be in line with users' need for institutions to respect their right to privacy.

The increased use of Information and Communication Technology (ICT) has meant that there is a vast increase in the collection and dissemination of private and confidential information on the web. Many of these systems have been designed and implemented with little regard for security and privacy issues and as a result, cyber crimes such as identity theft have been growing rapidly. Identity theft is one of the primary ways that fraudsters can take advantage of these systems. This paper focuses on consumer awareness of the protective measures they can take to prevent identity theft. The study uses an exploratory approach of measuring the self-reported behaviour of undergraduate students from different disciplines and age cohorts. The results are compared with a similar study of undergraduate students carried out in 2001 by George R.M Milne. In some instances, the US cohort indicated a more extensive awareness of the issues than the Irish cohort and in other instances the Irish cohort scored higher. What is clear, however, is that there are good practice preventative measures (behaviour) that consumers are not following. Further consumer education is needed. Based on these findings, suggestions are made for improving consumer awareness and future research is recommended.

Economic scheduling needs to be considered for the grid computing environment, because it gives an incentive for resource providers to supply their resources. Moreover, it enforces the efficient use of resources, because the users have to pay for their use. Tendering is a suitable model for grid scheduling because the users start the negotiations for finding suitable resources for executing their jobs. Furthermore, the users specify their job requirements with their requests and the resources reply with bids that are based on the cost of taking on the job and the availability of their processors. In this paper, a number of entity strategies are proposed. The entities, such as users, brokers and resources, employ tender/contract-net models to negotiate the prices and deadlines. The broker's role is to act on behalf of the users. During the negotiations, the entities aim to maximise their performance, which is measured by a number of metrics.

The European Megatrends project has analysed 26 major e-learning successes and ten conspicuous e-learning initiatives which did not reach targeted goals. There is much to learn from the many successful European e-learning initiatives, but this article focuses on what we can learn from the ten discontinued initiatives that spent about €150M before they were closed down after an average of four years in operation. The article presents the ten discontinued initiatives comprising four consortia, two institutional initiatives and four governmental and political initiatives. It includes a discussion on why they failed and concludes with seven recommendations that are drawn from the analyses of the ten initiatives.

Effective online learning requires both teachers and students to move beyond traditional face-to-face and correspondence modes and adopt strategies that take advantage of the flexibility and connectivity in the virtual or online classroom. In higher education, a common approach to connectivity is the use of online discussion forums, so the design and implementation of these forums significantly impacts on students' learning experience and outcomes. The case study used a grounded theory approach to generate insights into the critical success factors that promote student learning outcomes in online discussion forums in an Australian post-graduate online course. The paper outlines the findings and presents recommendations for the effective design of online forums.

Working in a virtual world creates new opportunities available for both students and teachers and introduces new challenges to their skills and resources. In particular, virtual worlds such as Second Life (SL) offer revolutionary and innovative modes for learning. These learning spaces are referred to as Virtual Learning Environments (VLEs) (Gredler, 2001; Jenkins, 2005). The guiding principle for the adoption of new VLEs by educators is that the particular features of each new Information and Communications Technology (ICT)-based tool should be used to provide specific benefits to the students' learning environments. While virtual worlds like SL are visually very rich environments where many types of stimuli and materials can be made available to students, the question is: what 'mainstream' university campus activities may be carried out completely within VLEs such as SL? We propose to explore this question and identify the potential to support teacher and learner interactions and activities within a virtual campus space of SL.

In an academic world largely dominated by instructor-facilitated learning environments (i.e., lecture halls and course management software), our research implements and measures the impact of a student-owned and operated virtual learning environment. Adopting an Action Design research methodology, we look to expand scholarships and build communities within our graduate school setting. More specifically, our research explores the impact of a user-defined Online Learning Community (OLC) on a group of 118 graduate students across 6 doctoral courses. Our findings reflect positively on a number of constructs, including perceived learning, social interaction and community and have provided our university with a proof-of-concept OLC, offering a valid alternative to traditional Course Management Systems (CMS).

Despite the significant investment and growth both in Europe and globally in the development of virtual universities and virtual campuses over the last decade, there have been a number of high-profile projects and initiatives that failed to achieve their intended goals. If such failures are to be avoided in the future, then it is vital that a better understanding of best practice within virtual universities and virtual campuses is achieved. This paper reports on the work of a European Commission Education Audiovisual & Culture Executive Agency (EACEA) co-financed project 'Promoting Best Practice in Virtual Campuses' (PBP-VC), which is aimed at providing a deeper understanding of the key issues and success factors underlying the implementation of virtual campuses. The paper will outline a tentative model of the issues underpinning best practice in virtual campuses which covers areas that include organisational, pedagogical, technological, student/user, financial and consolidation issues derived from an investigation into virtual campus projects and initiatives within Europe. The project is working towards developing a practical framework to help guide the process of creating best practice in virtual campuses, as well as raising awareness of issues and approaches to creating sustainable virtual campuses.
