The Knowledge Life Cycle for e-learning

In this paper, we examine the semantic aspects of e-learning from both pedagogical and technological points of view. We suggest that if semantics are to fulfil their potential in the learning domain then a paradigm shift in perspective is necessary, from information-based content delivery to knowledge-based collaborative learning services. We propose a semantics driven Knowledge Life Cycle that characterises the key phases in managing semantics and knowledge, show how this can be applied to the learning domain and demonstrate the value of semantics via an example of knowledge reuse in learning assessment management

The Open University Library in your pocket

The Open University library is working to support mobile learners through provision of mobile access to information management skills tutorials, the library website, and the library helpdesk. In 2007, we joined hands with the Athabasca University library team to develop the first mobile-friendly version of our library website. Since then, we have been actively researching and developing around other mobile library services, and more recently have consulted users to identify their requirements and what services they–d prefer to access through mobile phones. Recommendations from this user consultation (and from other sources, including regular users' feedback and by tracking user behavior through Google Analytics) include revamping the mobile version of the Library website to offer only the most used services on the home page, implementing SMS (Short Messaging Service) such as loan reminders or library reference service, and developing a consolidated search to offer results from various sources including the library catalogue and e-journals collection

The Platformisation of the European Mobile Industry

This paper argues that the structure of the mobile communications industry is being decisively affected by 'platformisation', yet in a present context of strong 'platform ambiguity'. It introduces the concept of gatekeeper roles to compare current mobile platform initiatives, and proposes a typology of platforms to characterise the various models encountered.Mobile Platforms, Business Models, Gatekeeping, Platform Typology

Options for Securing RTP Sessions

The Real-time Transport Protocol (RTP) is used in a large number of different application domains and environments. This heterogeneity implies that different security mechanisms are needed to provide services such as confidentiality, integrity, and source authentication of RTP and RTP Control Protocol (RTCP) packets suitable for the various environments. The range of solutions makes it difficult for RTP-based application developers to pick the most suitable mechanism. This document provides an overview of a number of security solutions for RTP and gives guidance for developers on how to choose the appropriate security mechanism

Creating mobile ePortfolios on mobile web servers

Electronic portfolios are inherently personal as they contain personal content and reflection of and commentary about collected content. In order to create a seamless way of collecting portfolio data, mobile devices can be used as the primary point of use for a portfolio author. Media-gathering is more tightly bound (through built-in audio/video recording facilities) and content can be created on the fly. As portfolios are characterized as being Web-based we can utilize appropriate technologies to serve Web-based content directly from a mobile phone. Nokia’s Mobile Web Server (MWS) is a port of the Apache Web Server for Series 60 Nokia Smartphones that includes a mechanism for accessing these mobile Web servers from the World Wide Web. A mobile user can therefore publish content directly on their phone and does not have to actively publish the information to a centralized server elsewhere on the Internet. In this paper we describe the current MWS applications that can be used for creating and organizing portfolio content and outline an analysis of why a portfolio would benefit from being hosted on a Mobile Web Server

Design & Deploy Web 2.0 enable services over Next Generation Network Platform

The Next Generation Networks (NGN) aims to integrate for IP-based telecom infrastructures and provide most advance & high speed emerging value added services. NGN capable to provide higher innovative services, these services will able to integrate communication and Web service into a single platform. IP Multimedia Subsystem, a NGN leading technology, enables a variety of NGN-compliant communications services to interoperate while being accessed through different kinds of access networks, preferably broadband. IMS-NGN services essential by both consumer and corporate users are by now used to access services, even communications services through the web and web-based communities and social networks, It is key for success of IMS-based services to be provided with efficient web access, so users can benefit from those new services by using web-based applications and user interfaces, not only NGN-IMS User Equipments and SIP protocol. Many Service are under planning which provided only under convergence of IMS & Web 2.0. Convergence between Web 2.0 and NGN-IMS creates and serves new invented innovative, entertainment and information appealing as well as user centric services and applications. These services merge features from WWW and Communication worlds. On the one hand, interactivity, ubiquity, social orientation, user participation and content generation, etc. are relevant characteristics coming from Web 2.0 services. Parallel IMS enables services including multimedia telephony, media sharing (video-audio), instant messaging with presence and context, online directory, etc. all of them applicable to mobile, fixed or convergent telecom networks. With this paper, this paper brings out the benefits of adopting web 2.0 technologies for telecom services. As the services are today mainly driven by the user's needs, and proposed the concept of unique customizable service interface

FORGE: An eLearning Framework for Remote Laboratory Experimentation on FIRE Testbed Infrastructure

The Forging Online Education through FIRE (FORGE) initiative provides educators and learners in higher education with access to world-class FIRE testbed infrastructure. FORGE supports experimentally driven research in an eLearning environment by complementing traditional classroom and online courses with interactive remote laboratory experiments. The project has achieved its objectives by defining and implementing a framework called FORGEBox. This framework offers the methodology, environment, tools and resources to support the creation of HTML-based online educational material capable accessing virtualized and physical FIRE testbed infrastruc- ture easily. FORGEBox also captures valuable quantitative and qualitative learning analytic information using questionnaires and Learning Analytics that can help optimise and support student learning. To date, FORGE has produced courses covering a wide range of networking and communication domains. These are freely available from FORGEBox.eu and have resulted in over 24,000 experiments undertaken by more than 1,800 students across 10 countries worldwide. This work has shown that the use of remote high- performance testbed facilities for hands-on remote experimentation can have a valuable impact on the learning experience for both educators and learners. Additionally, certain challenges in developing FIRE-based courseware have been identified, which has led to a set of recommendations in order to support the use of FIRE facilities for teaching and learning purposes
