Semantic-based policy engineering for autonomic systems

This paper presents some important directions in the use of ontology-based semantics in achieving the vision of Autonomic Communications. We examine the requirements of Autonomic Communication with a focus on the demanding needs of ubiquitous computing environments, with an emphasis on the requirements shared with Autonomic Computing. We observe that ontologies provide a strong mechanism for addressing the heterogeneity in user task requirements, managed resources, services and context. We then present two complimentary approaches that exploit ontology-based knowledge in support of autonomic communications: service-oriented models for policy engineering and dynamic semantic queries using content-based networks. The paper concludes with a discussion of the major research challenges such approaches raise

Framing the collaborative economy - Voices of contestation

Within the context of multiple crises and change, a range of practices discussed under the umbrella term of collaborative (or sharing) economy have been gaining considerable attention. Supporters build an idealistic vision of collaborative societies. Critics have been stripping the concept of its visionary potential, questioning its revolutionary nature. In the study, these debates are brought down to the local level in search for common perceptions among the co-creators of the concept in Vienna, Austria. Towards this aim a Q study is conducted, i.e. a mixed method enabling analyses of subjective perceptions on socially contested topics. Four framings are identified: Visionary Supporters, Market Optimists, Visionary Critics, and Skeptics, each bringing their values, visions, and practical goals characteristic of different understanding of the collaborative economy. The study questions the need for building a globally-applicable definition of the concept, calls for more context-sensitivity, exploratory studies, and city-level multi-stakeholder dialogues

Knowledge as Culture

Culture must not be seen as something that merely reflects an organization’s social reality: rather, it is an integral part of the process by which that reality is constructed. Knowledge management initiatives, per se, are not culture change projects; but, if culture stands in the way of what an organization needs to do, they must somehow impact

PeerPigeon: A Web Application to Support Generalised Peer Review

Peer Review (also known as Peer Assessment) is an important technique in learning, but can be difficult to support through e-learning due to the complexity and variety of peer review processes. In this paper we present PeerPigeon, a Web 2.0 style application that supports generalised Peer Review by using a canonical model of Peer Review based on a Peer Review Pattern consisting of Peer Review Cycles, each defined in terms of Peer Review Transforms. We also demonstrate how PeerPigeon makes use of a Domain Specific Language based on Ruby to define these plans, and thus cope with the irreducible complexity of the flow of documents around a peer network

Student Wiki Pages: Online collaboration in a networked environment

This chapter is concerned with student collaboration and ‘peer-support’ pedagogy as facilitated by online learning environments. Specifically the chapter discusses the use of wiki tools as part of the e-learning strategy in a first year BA (Hons) Communication and Media unit at Bournemouth University. The pedagogical aim here is to assess students’ ability to work effectively in a computer-mediated environment by applying interpersonal communication skills taught in the unit, whilst fostering a professional engagement with the unit’s theoretical foundation and facilitating student-centred learning. The Student Wiki Pages is an educational strategy that encourages students to develop active learning, media literacy and scholarship at the start of their degree programmes, providing a solid underpinning for their future studies. Collaboratively producing a wiki means students have to be self-reflexive and critically evaluate their own notes from lectures and set readings on a weekly basis. Drawing on evidence from 2010/2011, the chapter will demonstrate how the Student Wiki Pages helped inspire students’ commitment to learning by analysing five core areas where student performance improved. Practical complexities of assessing collaborative learning will be evaluated, together with a discussion on how to manage student expectations in relation to grading and feedback
