Social Navigation and Local Folksonomies: Technical and Design Considerations for a Mobile Information System
No full textWeb services such as wikis, blogs, podcasting, file sharing and social networking are frequently referred to by the term Web 2.0. The innovation of these services lies in their ability to enable an increasing number of users to actively participate on the Internet by creating and sharing their own content and help develop a collective intelligence. In this paper we discuss how we use Web 2.0 techniques such as 'folksonomy' and 'geo-tagging' in a mobile information system to collect and harness the everyday connections and local knowledge of urban residents in order to support their social navigation practices
Identifying new virtual competencies for the digital age :\ud essential tools for entry level workers
No full textThis chapter focuses on the identification of a range of competencies that entry level workers, and thus graduating students, will need to acquire to be successful in the 21st Century of work. While core or basic competencies will still form the prerequisite generic skills that all entry level workers must demonstrate,\ud
as the first year progresses, depending on the field in which they are employed, they will be asked to utilise self management, entrepreneurial, and virtual competencies in order to maintain their employment status. Even if they have ICT skills, they will need to have the knowledge and ability in social software, as well as the ability to communicate across the web, in order to succeed in the digital age. Other attributes, such as cross cultural and professional skills, along with an appreciation of Web ontologies will facilitate entry-level workers as they move into the world of international liaisons
Finite Element Modelling of a Deep Excavation in Boston Blue Clay
No full textAbstractThe work investigates the behaviour of a deep excavation that forms part of a wide basement located in Boston, Massachusetts, USA. The glacial marine clay deposit is modelled with a kinematic hardening model for structured soils, its reduced bubble model version and the well-known Modified Cam Clay model. The aim of the work is to assess the effects of the added features of the advanced model, such as small-strain stiffness, structure degradation and anisotropy, on the numerical prediction of the overall behaviour of the excavation. The first part of the paper provides a brief description of the site conditions, ground profile and construction sequences for the case study under consideration. Then, the soil model calibration process using experimental undrained triaxial, self-boring pressuremeter and constant rate of strain consolidation tests is discussed. Finally, the comparison of the predicted wall deflection and ground settlements profiles with observed movements is presented
Presence in social networks
No full textThis chapter describes the mechanisms of presence in social networks and presents an ontology that frames the purpose, content, methods of production and methods of consuming presence information. The concept of presence in social networks has been steadily evolving along with the Internet. Recognised as an essential feature of all instant messaging services from the IRC onwards, mechanisms for constructing and consuming presence information have become more elaborate, with the addition of more sophisticated mechanisms for producing, consuming and representing presence. A model for systems that offer presence services is developed, and this enables a number of future trends to be identified
Bridging the gap between Web 2.0 and higher education
No full textThis chapter looks at some of the areas of tension between the new social networking, Web 2.0 communities and the values of higher education. It argues that both the granularity of formal education and the manner in which the authors formalize learning are subject to change with the advent of digital technologies and user generated content. The gap between higher education and Web 2.0 could be bridged by, amongst other approaches, a sort of flickr for learning design, which allows users to share activities and sequences, thus meeting the diverse needs of learners and utilising the best of social networking approaches
Knowledge media tools to foster social learning
No full textThe aim of this chapter is to overview the ways in which knowledge media technologies create opportunities for social learning. The Open Content movement has been growing rapidly, opening up new opportunities for widening participation. One of the Open Educational Resources (OER) initiatives is the OpenLearn project, launched by the Open University, which integrates three knowledge media technologies: Compendium, FM and MSG. In this chapter, the authors analyse some examples, which show how these tools can be used to foster open sensemaking communities by mapping knowledge, location and virtual interactions. At the end, they present some questions and future horizons related to this research. © 2009, IGI Global
Exploring the role of social software in higher education
No full textThis chapter considers the potential of social software to support learning in higher education. It outlines a current project funded by the then Australian Carrick Institute for Learning and Teaching in Higher Education, now the Australian Learning and Teaching COuncil (ALTC) (http://www.altc. edu.au/carrick/go) to explore the role of social software in supporting peer engagement and group learning. The project has established a series of pilot projects that examine ways in which social software can provide students with opportunities to engage with their peers in a discourse that explores, interrogates and provides a supplementary social ground for their in-class learning. Finding creative ways of using technology to expand and enrich the social base of learning in higher education will become increasingly important to lecturers and instructional designers alike. This project represents one small step in testing the applicability of social software to these contexts. While many of our students are already using various technologies to maintain and develop their personal networks, it remains to be seen if these offer viable uses in more scholarly settings.</jats:p
