Personal ICT Ensembles and Ubiquitous Information Systems Environments: Key Issues and Research Implications

Personal information and communication technologies (ICTs) have become commonplace. Today many people own, or have access to, a range of different computing and communication devices, information technologies, and services, which they incorporate into their everyday routines. Increasingly, these technologies impact the way that individuals work, socialize, and play. Workers are bringing their personal ICTs to the office, and organizations are tailoring their computing environments toward ubiquitous integration with personal ICTs. These developments are opening up new ways of working, but they also create new challenges for organizations in accommodating this “nonaffiliated” use as part of their information systems environments. In this article we propose a framework for analyzing the composition and impact of personal ICT ensembles. The framework is positioned as pre-theory that invites further development and empirical testing. We illustrate how the proposed framework could be applied to consider personal ICT use across the work/home context. Several implications stemming from the notion of a personal ICT ensemble are highlighted, including practical considerations for nonaffiliated use in organizations. We conclude with suggestions for further development of the proposed framework.

Tablet technologies in early childhood: pedagogical possibilities and limitations

Drawing from recent research literature, this article analyses the paradigmatic and pedagogical shifts occurring in early childhood education due to the emergence of new digital technologies. Over the past decade the role that computers and other digital technologies have played in supporting young children’s learning have been well documented. However, new pedagogical possibilities to support children’s play, learning and inquiries are arising due to tablet technologies (For example, Apple iPads, Kindle or Google Chrome OS). This article has reviewed and analysed recently published research findings in the Australian early childhood context (preschool through to the first year of primary school) considering how tablet technologies are used and understood in this environment. A critical discourse analysis has identified pedagogical possibilities and limitations experienced by teachers, children and their families, when tablet technologies are used as a resource to support children’s play and learning.

Automatic generation of meta classifiers with large levels for distributed computing and networking

This paper is devoted to a case study of a new construction of classifiers. These classifiers are called automatically generated multi-level meta classifiers, AGMLMC. The construction combines diverse meta classifiers in a new way to create a unified system. This original construction can be generated automatically producing classifiers with large levels. Different meta classifiers are incorporated as low-level integral parts of another meta classifier at the top level. It is intended for the distributed computing and networking. The AGMLMC classifiers are unified classifiers with many parts that can operate in parallel. This make it easy to adopt them in distributed applications. This paper introduces new construction of classifiers and undertakes an experimental study of their performance. We look at a case study of their effectiveness in the special case of the detection and filtering of phishing emails. This is a possible important application area for such large and distributed classification systems. Our experiments investigate the effectiveness of combining diverse meta classifiers into one AGMLMC classifier in the case study of detection and filtering of phishing emails. The results show that new classifiers with large levels achieved better performance compared to the base classifiers and simple meta classifiers classifiers. This demonstrates that the new technique can be applied to increase the performance if diverse meta classifiers are included in the system.

Integrating internet-of-things with the power of cloud computing and the intelligence of big Data analytics- a three layered approach

This paper is written through the vision on integrating Internet-of-Things (IoT) with the power of Cloud Computing and the intelligence of Big Data analytics. But integration of all these three cutting edge technologies is complex to understand. In this research we first provide a security centric view of three layered approach for understanding the technology, gaps and security issues. Then with a series of lab experiments on different hardware, we have collected performance data from all these three layers, combined these data together and finally applied modern machine learning algorithms to distinguish 18 different activities and cyber-attacks. From our experiments we find classification algorithm RandomForest can identify 93.9% attacks and activities in this complex environment. From the existing literature, no one has ever attempted similar experiment for cyber-attack detection for IoT neither with performance data nor with a three layered approach.

Intelligent internet computing: applications and security systems

Intelligent Internet Computing (IIC) is emerging rapidly as an exciting new paradigm including pervasive, grid, and peer-to-peer computing to provide computing and communication services any time and anywhere. IIC paradigm foresees seamless integration of communicating and computational devices and applications embedded in all parts of our environment, from our physical selves, to our homes, our offices, our streets and so on. Although IIC presents exciting enabling opportunities, the benefits will only be realized if application and security issues can be appropriately addressed. This special issue is intended to foster the dissemination of state-of-the-art research in the area of IIC, including novel applications associated with its utilization, security systems and services, security models. We plan to publish high quality manuscripts, which cover the various practical applications and related security theories of IIC. The papers should not be submitted simultaneously for publication elsewhere. Submissions of high quality papers describing mature results or on-going work are invited. Selected high-quality papers from “the Eleventh IEEE International Conference on High Performance Computing and Communications (HPCC-09) and the Third International Conference on Information Security and Assurance (ISA-09),” will be published in this special issue of Journal of Internet Technology on "Intelligent Internet Computing".

Developing and asynchronous learning network

Deakin University, Australia, has committed resources over a number of years to developing the use of information and communication technologies in all aspects of teaching and learning. This paper focuses on the development over a four year period of an Asynchronous Learning Network (ALN) for distance education students studying undergraduate introductory macroeconomics. The research is based on quantitative and qualitative data gained from student evaluations, academic staff interviews, participation levels and an analysis of the online communication. Key findings from the research relate to the quality of the learning environment, the level of communication, and the role of academic staff in the learning experience. Strategies discussed for the successful use of an ALN include the nurturing of a collaborative learning environment, the adaptation of curriculum and pedagogy, the role of assessment, and the role of academic staff training and development.

The Digital Divide: Differences in Computer Use between Home and School in Low Socio-economic Households

This article examines information and communication technologies(ICTs) practices in the home and school settings of four disadvantaged families. It reports the findings of a year-long study that investigated the nexus between computer-mediated literacy practices at home and at school and whether this inter-connectivity could make a difference in school success. The findings indicate that there was disjunction between home and school use. The ``digital divide'' exists for the families of this study, not in terms of access but in the gap between ICT practices at home and school. Schools in this study did not integrate ICT skills learned and demonstratedin the home environment into ICT practices at school. The study concludes that constructing pedagogical connections between home and school ICT practices may begin to bridge the ``digital divide''.

Pain and communication

It is frequently said that pain is incommunicable and even that it destroys language. This paper offers a phenomenological account of pain and then explores and critiques this view. It suggests not only that pain is communicable to an adequate degree for clinical purposes, but also that it is itself a form of communication through which the person in pain appeals to the empathy and ethical goodness of the clinician. To explain this latter idea and its ethical implications, reference is made to the writings of Emmanuel Levinas.

Flexible learning in teacher education: myths, muddles and models

While there has been widespread take-up of the concept 'flexible learning' within various educational environments—and equally frequent references to the flexible 'natures' of the computer and communication technologies that often underpin flexible learning initiatives—the relationship between technologies and flexibility is not a simple one. In this paper we examine some of the more persistent myths about technologies that are intertwined with discourses of flexibility. We highlight some of the more common 'muddles' that these myths can lead us in to and argue that the 'mess' that so often results from well-intentioned moves to 'be more flexible' is largely a result of the ways that CCTs, or indeed any new educational technology or strategy, is theorized. Drawing on a recent study of online teaching and learning in higher education, we outline a new framework for examining these and related issues as they apply to teacher education.

Speed, international security, and "New War" coverage in cyberspace

Mass media representations foster a view that the "War on Terror" is taking place both everywhere and nowhere, presenting Western governments with an opportunity to mobilize public support in new and ubiquitous ways. Starting with Virilio's critique of technology, speed, and de-territorialization, this article discusses the ways in which mass support is mobilized by the state in conventional pursuit of geopolitical objectives. Drawing on  contemporary international relations theory, the authors introduce the concept of "securitization" and discuss how war coverage in cyberspace has been used to securitize international threats, such as "global terrorism," to justify state intervention, including war. It is concluded that one of the paradoxes of war coverage in cyberspace is that whereas cyber-technologies should democratize the politics of war by liberating access to information about war, the state has coopted information and communication technologies to facilitate new forms of mass mobilization for war itself.

The role of information and communication technology in the urgent decision making process : a work in progress report

This paper reports part of a study that examines how members of a senior management team in a public sector organisation make decisions under urgency. Four regional managers, who are geographically dispersed around New Zealand were interviewed, either face-to-face or via telephone, regarding their experiences of decision making under urgency.

Preliminary results indicate that only three out of a possible seven steps of a conventional decision making process are used during the urgent decision making process. The study also shows that participants do not fully utilise the information and communication technology available during the decision making process. The implications the findings have for practice and research are discussed.

Globalisation and reflexivity: some challenges for research into quality education mediated by ICTs

Globalisation can be characterised, Giddens (1994) suggests, as a process of 'intensified reflexivity' that creates the conditions for 'a world of clever people'. Information and Communication Technologies (ICTs) are fundamental to globalisation and they have also been incorporated into the new educational technologies deployed by educators to (re)create 'a world of clever people'. Together, education and the ICTs are strong forces for globalisation where both curriculum and pedagogy shape the knowledge and values of the rising generation of 'clever people'. This chapter posits some research issues and questions that might be usefully pursued in transnational collaborative research or are germane to its conduct and contexts. These matters include: the place of ICTs in research work; the challenge of globally inclusive curricula and the impact of English as the global language; and ICTs decentring the research centre.
