The disappearing mammal fauna of northern Australia : context, cause, and response

This article provides a context to, attempts an explanation for, and proposes a response to the recent demonstration of rapid and severe decline of the native mammal fauna of Kakadu National Park. This decline is consistent with, but might be more accentuated than, declines reported elsewhere in northern Australia; however, such a comparison is constrained by the sparse information base across this region. Disconcertingly, the decline has similarities with the earlier phase of mammal extinctions that occurred elsewhere in Australia. We considered four proximate factors (individually or interactively) that might be driving the observed decline: habitat change, predation (by feral cats), poisoning (by invading cane toads), and novel disease. No single factor readily explains the current decline. The current rapid decline of mammals in Kakadu National Park and northern Australia suggests that the fate of biodiversity globally might be even bleaker than evident in recent reviews, and that the establishment of conservation reserves alone is insufficient to maintain biodiversity. This latter conclusion is not new; but the results reported here further stress the need to manage reserves far more intensively, purposefully, and effectively, and to audit regularly their biodiversity conservation performance.

University entrepreneurship : context, process and performance

This project embraced empirical work that studied existing research commercialization systems (RCS) at both first tier and second tier universities, found them flawed and produced an enhanced framework that is definitely applicable to second tier universities (the vast majority) and possibly applicable to first tier universities as well.

Moving beyond a ‘bums-on-seats’ analysis of progress towards widening participation: reflections on the context, design and evaluation of an Australian government-funded mentoring programme

In 2010 the Australian Government established the Higher Education Participation and Partnerships programme – a funding agenda to promote programmes that respond to the underrepresentation in higher education of people from what is often denoted low socioeconomic status (SES) backgrounds. Many government-funded programmes and projects have since emerged that respond to the problem of low SES underrepresentation, based on partnerships between higher education providers and other organisations. The arguments made in this paper draw on one such project: a mentoring programme implemented from 2011 to 2013 that targeted the aspirations of Year 9 regional secondary students. We discuss data and documentation that provide insights into the conception and design of the mentoring programme, and the strategies used to evaluate it, in order to discuss how funding and policy contexts influences the possible solutions that might be implemented in response to the underrepresentation in higher education of people from low SES backgrounds.

Life-context interactions and their contributions to postgraduate distance learning

 This thesis explores the learning contributions of interactions between distance learners and other people in their lives about the academic content of their studies. It proposes new ways of conceptualising learning and learner interaction modes in distance education, and a new approach to distance education program design.

Navigating the demands of the English schooling context: problematics and possibilities for social equity

The English schooling context has seen radical and rapid reform in recent times with the processes of devolution or deconcentration of centralised school governance, on the one hand, and the instating of ever-increasing and rigid external accountabilities, on the other. These reforms driven as they are by neoliberal and neoconservative ideologies have created a new kind of ‘system’ of schooling in England, one that is ‘heterarchical’ in governance, increasingly complex in its overlap, multiplicity and asymmetric power dynamics, but one that remains strongly tied to and regulated by the reductive and narrow measure of ‘success’ imposed by the state. Against this complex and changing backdrop, what constitutes quality and equitable schooling has been transformed. This special issue explores these concerns and, in particular, focuses on how the current demands of the English schooling context construct student achievement and identity, teachers’ work, conceptualisations of knowledge and pedagogy, and school organisation and collaboration. The issue has a strong equity focus. Many of the papers to this end focus on how teachers and schools are navigating through the demands of current policy reform to mobilise spaces of possibility for equity and good schooling. In this paper, we provide a context and framework to set the scene for the subsequent papers in the issue.

A shadow-like task migration model based on context semantics for mobile and pervasive environments

Pervasive computing is a user-centric mobile computing paradigm, in which tasks should be migrated over different platforms in a shadow-like way when users move around. In this paper, we propose a context-sensitive task migration model that recovers program states and rebinds resources for task migrations based on context semantics through inserting resource description and state description sections in source programs. Based on our model, we design and develop a task migration framework xMozart which extends the Mozart platform in terms of context awareness. Our approach can recover task states and rebind resources in the context-aware way, as well as support multi- modality I/O interactions. The extensive experiments demonstrate that our approach can migrate tasks by resuming them from the last broken points like shadows moving along with the users.

Editorial : towards merging grid and pervasive computing

This special issue is in response to the increasing convergence between grids and pervasive computing, while different approaches exist, challenges and opportunities are numerous in this context (Parashar and Pierson, to appear). The research papers selected for this special issue represent recent progresses in the field, including works on mobile ad-hoc grids, service and data discovery, context-aware application building and context accuracy, and communication. All of these papers not only provide novel ideas and state-of-the-art techniques in the field, but also stimulate future research in the Pervasive Grid environment.

Context-based e-health system access control mechanism

E-Health systems logically demand a sufficiently fine-grained authorization policy for access control. The access to medical information should not be just role-based but should also include the contextual condition of the role to access data. In this paper, we present a mechanism to extend the standard role-based access control to incorporate contextual information for making access control decisions in e-health application. We present an architecture consisting of authorisation and context infrastructure that work cooperatively to grant access rights based on context-aware authorization policies and context information.

Design management methodology to strengthen firm and industry competitiveness in the construction design services export sector

The aim of this research was to investigate strategies deployed by successful construction design-related firms towards achieving high levels of firm competitiveness in international markets. A reflexive capability model, developed through a critical analysis of related internationalisation literature, is composed of three key areas; internationalisation process, market knowledge and design management. Firm reflexive capability is explored through the management of social, cultural and intellectual capital. The concept of reflexivity is borrowed from sociology. Reflexivity is reinterpreted as the ‘firm’s’ ability to be aware, responsive and adaptable to self, market and project needs assessment. A cross case analysis explored the barriers and success factors through three constructs; internationalisation process, design management and market knowledge of three firms. This paper demonstrates that international firm competitiveness is dependent upon the strategic inter-relational management of social, cultural and intellectual capital for maximum advantage of the utilisation and leverage of one form of capital to gain another. This leads to the development of increasing reflexive capability to support internationalisation. An outcome of this research is the identification of the central relation between a level of reflexive capability within the firm and the firm’s level of success in international markets. This research is part of an ongoing program of research on international collaborative practice. A Reflexive Capability Matrix was developed from the findings of one research project and then validated through a second research project (only the capability matrix is presented in this paper though). The reflexive capability approach is appropriate to all firms but what is speculated upon is that the reflexive capability is particularly intrinsic to small to medium sized construction design firms who work globally. A reflexive capability is a characteristic of successful and innovative firms internationalising and working within global models of practice.

Analysis and modelling of critical infrastructure systems

The increasing complexity and interconnectedness of critical infrastructure systems, including the information systems and communication networks that support their existence and functionality, poses questions and challenges. Particularly, in terms of modelling and analysis of the security, survivability and ultimately reliability and continued availability of critical infrastructure systems and the services they deliver to modern society. The focus of this research enquiry is with regard to critiquing and modelling critical infrastructure systems. There are numerous systems analyse and modelling approaches that outline any number of differing methodological approaches, each with their own characteristics, expertise, strengths and weaknesses. The intention of this research is to investigate the merit of applying a ‘softer’ approach to critical infrastructure system security analysis and modelling that broadly views the systems in holistic terms, including their relationships with other systems. The intention is not to discuss or criticise existing research applying quantitative approaches, but to discuss a ‘softer’ system analysis and modelling approach in a security context that is adaptable to analysis modelling of critical infrastructure systems.

Context reinstatement effects in children’s cued recall of strongly and weakly associated word pairs

Typically, asking people to reinstate the context of events increases their recall of those events; however, research findings have been mixed with children. We tested whether the principle underlying context reinstatement applies to children as it does to adults. This underlying principle, encoding specificity, suggests that the greater the overlap between study context cues and retrieval context cues, the more information that people should recall. In the current experiment, four age groups (7-year-olds, 9-year-olds, 11-year-olds and adults) took part in an encoding specificity procedure. At study, participants saw cue– target word pairs in which the cue word was either a strong or a weak associate of the target word (e.g., ice–COLD; blow–COLD). During an immediate cued recall test, participants were presented with the same strong or weak cue words and new, extra-list cue words. Overall, children and adults recalled more targets when they were presented with the same cue words at study and test, regardless of whether the cues were strong or weak. This finding suggests that encoding specificity applies to children as well as adults. We discuss the implications of these results.

Digital systems for open access to formal and informal learning

 Today, Digital Systems and Services for Technology Supported Learning and Education are recognized as the key drivers to transform the way that individuals, groups and organizations “learn” and the way to “assess learning” in 21st Century. These transformations influence: Objectives - moving from acquiring new “knowledge” to developing new and relevant “competences”; Methods – moving from “classroom” based teaching to “context-aware” personalized learning; and Assessment – moving from “life-long” degrees and certifications to “on-demand” and “in-context” accreditation of qualifications. Within this context, promoting Open Access to Formal and Informal Learning, is currently a key issue in the public discourse and the global dialogue on Education, including Massive Open Online Courses (MOOCs) and Flipped School Classrooms.
