E-poltergeist takes over the user’s internet browser, automatically initiating Web searches without their permission. Web-based artwork which explores issues of user control when confronted with complex technological systems, questioning the limits of digital interactive arts as consensual reciprocal systems. e-poltergeist was a major web commission that marked an early stage of research in a larger enquiry by Craighead and Thomson into the relationship between live virtual data, global communications networks and instruction-based art, exploring how such systems can be re-contextualised within gallery environments. e-poltergeist presented the 'viewer' with a singular narrative by using live internet search-engine data that aimed to create a perpetual and virtually unstoppable cycle of search engine results, banner ads and moving windows as an interruption into the normal use of an internet browser. The work also addressed the ‘de-personalisation’ of internet use by sending a series of messages from the live search engine data that seemed to address the user directly: 'Is anyone there?'; 'Can anyone hear me?', 'Please help me!'; 'Nobody cares!' e-poltergeist makes a significant contribution to the taxonomy of new media art by dealing with the way that new media art can re-address notions of existing traditions in art such as appropriation and manipulation, instruction-based art and conceptual art. e-poltergeist was commissioned ($12,000) for 010101: Art in Technological Times, a landmark international exhibition presented by the San Francisco Museum of Modern Art, which bought together leading international practitioners working with emergent technologies, including Tatsuo Miyajima, Janet Cardiff, Brian Eno. Peer recognition of the project in the form of reviews include: Curating New Media. Gateshead: Baltic Centre for Contemporary Art.

The emerging technologies have expanded a new dimension of self – ‘technoself’ driven by socio-technical innovations and taken an important step forward in pervasive learning. Technology Enhanced Learning (TEL) research has increasingly focused on emergent technologies such as Augmented Reality (AR) for augmented learning, mobile learning, and game-based learning in order to improve self-motivation and self-engagement of the learners in enriched multimodal learning environments. These researches take advantage of technological innovations in hardware and software across different platforms and devices including tablets, phoneblets and even game consoles and their increasing popularity for pervasive learning with the significant development of personalization processes which place the student at the center of the learning process. In particular, augmented reality (AR) research has matured to a level to facilitate augmented learning, which is defined as an on-demand learning technique where the learning environment adapts to the needs and inputs from learners. In this paper we firstly study the role of Technology Acceptance Model (TAM) which is one of the most influential theories applied in TEL on how learners come to accept and use a new technology. Then we present the design methodology of the technoself approach for pervasive learning and introduce technoself enhanced learning as a novel pedagogical model to improve student engagement by shaping personal learning focus and setting. Furthermore we describe the design and development of an AR-based interactive digital interpretation system for augmented learning and discuss key features. By incorporating mobiles, game simulation, voice recognition, and multimodal interaction through Augmented Reality, the learning contents can be geared toward learner's needs and learners can stimulate discovery and gain greater understanding. The system demonstrates that Augmented Reality can provide rich contextual learning environment and contents tailored for individuals. Augment learning via AR can bridge this gap between the theoretical learning and practical learning, and focus on how the real and virtual can be combined together to fulfill different learning objectives, requirements, and even environments. Finally, we validate and evaluate the AR-based technoself enhanced learning approach to enhancing the student motivation and engagement in the learning process through experimental learning practices. It shows that Augmented Reality is well aligned with constructive learning strategies, as learners can control their own learning and manipulate objects that are not real in augmented environment to derive and acquire understanding and knowledge in a broad diversity of learning practices including constructive activities and analytical activities.

Adequate user authentication is a persistent problem, particularly with mobile devices, which tend to be highly personal and at the fringes of an organisation's influence. Yet these devices are being used increasingly in various business settings, where they pose a risk to security and privacy, not only from sensitive information they may contain, but also from the means they typically offer to access such information over wireless networks. User authentication is the first line of defence for a mobile device that falls into the hands of an unauthorised user. However, motivating users to enable simple password mechanisms and periodically update their authentication information is difficult at best. This paper examines some of the issues relating to the use of biometrics as a viable method of authentication on mobile wireless devices. It is also a critical analysis of some of the techniques currently employed and where appropriate, suggests novel hybrid ways in which they could be improved or modified. Both biometric technology and wireless setting based constraints that determine the feasibility and the performance of the authentication feature are specified. Some well known biometric technologies are briefly reviewed and their feasibility for wireless and mobile use is reviewed. Furthermore, a number of quantitative and qualitative parameters for evaluation are also presented. Biometric technologies are continuously advancing toward commercial implementation in wireless devices. When carefully designed and implemented, the advantage of biometric authentication arises mainly from increased convenience and coexistent improved security.

Today more than 99% of plastics are petroleum-based because of availability and cost of the raw material. The durability of these disposed plastics contributes to the environmental problems as waste and their persistence in the environment causes deleterious effects on the ecosystem. Environmental pollution awareness and the demand for green technology have drawn considerable attention of both academia and industry into biodegradable polymers. In this regard green chemistry technology has the potential to provide solution to this problematic issue. Laccase bio-grafting has recently been the focus of green chemistry technologies due to the growing environmental concerns, legal restrictions and increasing availability of scientific knowledge. In the last several years, research covering various applications of laccases has been increased rapidly particularly in the field of grafting. In principle, laccase-assisted graft co-polymerization may impart a variety of new functionalities to a polymer. The modified polymers through grafting have a bright future and their development is practically boundless. In present work, novel biodegradable graft copolymers combining the advantages of bacterial cellulose backbone and PHB side chains will be prepared by introducing enzymatic grafting technique. The present research will be a first step in the biopolymer modification. To date no report has been found in literature explaining the enzymatic grafting of PHAs. The technique would also provide an efficient modulation approach to improve the biodegradability and biocompatibility of the graft copolymer. The newly grafted copolymers will exhibit unique functionalities with wider range of potential applications mainly in tissue engineering, biosensors, pharmaceutical industry (drug delivery systems) and bio-plastics.

This chapter reports on a study of teachers in transition, developing their practice and their cognitions regarding the integration of learning technologies with traditional approaches to the teaching of English for Academic Purposes (EAP). Taking a case study approach, it examines developments in the practice of three teachers during and after a teacher education programme on the use of technology in the EAP classroom. This is a study of cognition, teaching philosophy, and the relationship between pedagogy, technology, and content, and how teachers situate these within their own practice. The setting is the rapidly changing UK higher education environment, where the speed of change is such that today's latest fashions and gadgets may well be yesterday's news tomorrow. Thus, this is not a tale of individual technologies or tools to make teachers' lives better. This is a story of people, of pedagogy's traditional values intersecting with technology, and the issues arising from this, alongside the evolution of strategies for dealing with these issues.
