    This paper discusses the importance of learning context with a particular focus upon the educational application of mobile technologies. We suggest that one way to understand a learning context is to perceive it as a Learner Centric Ecology of Resources. These resources can be deployed variously but with a concern to promote and support different kinds of mediations, including those of the teacher and learner. Our approach is informed by sociocultural theory and is used to construct a framework for the evaluation of learning experiences that encompass various combinations of technologies, people, spaces and knowledge. The usefulness of the framework is tested through two case studies that evaluate a range of learning contexts in which mobile technologies are used to support learning. We identify the benefits and challenges that arise when introducing technology across multiple locations. An analytical technique mapped from the Ecology of Resources framework is presented and used to identify the ways in which different technologies can require learners to adopt particular roles and means of communication. We illustrate how we involve participants in the analysis of their context and highlight the extent to which apparently similar contexts vary in ways that are significant for learners. The use of the Ecology of Resources framework to evaluate a range of learning contexts has demonstrated that technology can be used to provide continuity across locations: the appropriate contextualization of activities across school and home contexts, for example. It has also provided evidence to support the use of technology to identify ways in which resources can be adapted to meet the needs of a learner

    Maintaining, changing and crossing contexts: an activity theoretic reinterpretation of mobile learning

    Although mobile learning is a popular topic in current research, it is not well conceptualized. Many researchers rely on underā€theorized conceptions of the topic, and those who have tried to refine the ideas involved have found this to be complex and difficult. In this paper a new interpretation of the concept ā€˜mobile learningā€™ is offered, drawing on the tradition of activity theory. The interpretation focuses on the continuity of learning activities that take place in multiple contexts, which are embodied as the combination of the physical and social setting of the learning activities. The paper starts by sketching the current research context and then outlines the theoretical tradition within which the interpretation of ā€˜mobile learningā€™ is located. Then the new interpretation is offered and the concepts are applied to case studies to illustrate how this new understanding develops current thinking in the area. The paper concludes by discussing the implications for research of adopting such a perspective

    The purpose of this research is to analyze the role of the Management Control System (MCS) and of the Management Accounting System (MAS) in healthcare (HC) organizations. It aims at studying if and how managerial considerations affect the clinical culture. Results are based on the findings of a research developed within 12 Local Health Authorities (Aziende Sanitarie Locali LHAs) and 4 Teaching Hospital (Aziende Ospedaliere Universitarie THs) in Italian Tuscany Region and address the possibility to develop an alternative model from those of accountingization or legitimation proposed in literature to understand the role of these systems in healthcare. Results highlight that the economic language may assume a great importance in cliniciansā€™ decision making and penetrates into clinical culture. Most important factor affecting results is the development of an alliance between controllers and clinicians, based trust and collaboration. The paper is a contribution to the literature about the role of MCS and MAS in healthcare and it is developed within the schemes traced by Habermas and refined by Laughlin and by Broadbent and Laughlin. The original value stands on the individuation of a model where the ā€œintegrative interactiveā€ management model is able to penetrate clinical discourse and the conditions at which it can be developed.Management Accounting Change, Management Control Change, Healthcare Accounting, Professional organization, accountinization, legitimation, Habermas

    The possibilities of the digital future require new models for procurement, innovation and exploitation. Emma Crowley and Chris Spencer describe the skills staff need to deliver resources in hybrid and digital environments. The chapter demonstrates the innovative ways that librarians use to procure and exploit the wealth of resources available in a digital world. They also describe the technological developments that can be adopted to improve workflow processes and they highlight the challenges faced on this fascinating journey

    Video summarisation: A conceptual framework and survey of the state of the art

    This is the post-print (final draft post-refereeing) version of the article. Copyright @ 2007 Elsevier Inc.Video summaries provide condensed and succinct representations of the content of a video stream through a combination of still images, video segments, graphical representations and textual descriptors. This paper presents a conceptual framework for video summarisation derived from the research literature and used as a means for surveying the research literature. The framework distinguishes between video summarisation techniques (the methods used to process content from a source video stream to achieve a summarisation of that stream) and video summaries (outputs of video summarisation techniques). Video summarisation techniques are considered within three broad categories: internal (analyse information sourced directly from the video stream), external (analyse information not sourced directly from the video stream) and hybrid (analyse a combination of internal and external information). Video summaries are considered as a function of the type of content they are derived from (object, event, perception or feature based) and the functionality offered to the user for their consumption (interactive or static, personalised or generic). It is argued that video summarisation would benefit from greater incorporation of external information, particularly user based information that is unobtrusively sourced, in order to overcome longstanding challenges such as the semantic gap and providing video summaries that have greater relevance to individual users
