    This paper explores the role of the traditional computational metaphor in our thinking as computer scientists, its influence on epistemological styles, and its implications for our understanding of cognition. It proposes to replace the conventional metaphor--a sequence of steps--with the notion of a community of interacting entities, and examines the ramifications of such a shift on these various ways in which we think

    Challenging Party Hegemony: Identity Work in China’s Emerging Virreal Places

    Get PDF
    The Chinese Communist Party has chosen to base the legitimacy of its rule on its performance as leading national power. Since national identity is based on shared imaginations of and directly tied to territory – hence place, this paper analyses both heterodox models for identification on the national and potentially competing place-based collective identities on the local level. This analysis, based on communication within a number of popular communication forums and on observation of behavior in the physical reality of today’s urban China, shows that communication within the virtual and behavior in the real world are not separated realities but form a new virreal spatial continuum consisting of imagined places both online and offline. I argue that ties to place are stronger and identities constructed on shared imaginations of place are more salient the more direct the experience of place is – be the place real, virtual or virreal. Hence in China challenges to one-party rule will probably accrue from competing localized collective identities rather than from heterodox nationalism.to explore the variety and complexity of functional antagonisms in the social subsystems.China, Internet, political power, collective identity, nationalism, place, bulletin, board system, online communication, online community

    Using shared online blogs to structure and support informal coach learning Part 1: A tool to scaffold reflection and communities of practice?

    Coaches’ apparent preferences for informal and self-directed modes of learning have been highlighted in the literature. Consequently, there is a need for innovative coach education approaches that complement these clearly preferred, informal routes, and better provide coaches with the professional skills they need to deal with the complex nature of their work. Online blogs are one such tool said to have the potential to strengthen and promote critical thinking and reflection on professional practice; however, research evidence and theoretical frameworks for their use is inconclusive and currently lacking. Therefore, the purpose of part one of this two-part investigation was to explore the use of shared online blogs as a tool to promote reflection and community of practice (CoP) in a cohort of twenty-four undergraduate sports coaching students (5 females, 19 males). Four group blogs, purposely designed to support informal workplace learning, were subjected to content analysis in order to determine the emergent reflective quality of blog entries, and the extent to which functioning online CoPs emerged. Findings revealed that shared blogs were a useful tool to promote higher order reflective thinking, and fully functioning online CoPs emerged in all four groups

    Conspiratorial beliefs observed through entropy principles

    We propose a novel approach framed in terms of information theory and entropy to tackle the issue of conspiracy theories propagation. We start with the report of an event (such as 9/11 terroristic attack) represented as a series of individual strings of information denoted respectively by two-state variable Ei=+/-1, i=1,..., N. Assigning Ei value to all strings, the initial order parameter and entropy are determined. Conspiracy theorists comment on the report, focusing repeatedly on several strings Ek and changing their meaning (from -1 to +1). The reading of the event is turned fuzzy with an increased entropy value. Beyond some threshold value of entropy, chosen by simplicity to its maximum value, meaning N/2 variables with Ei=1, doubt prevails in the reading of the event and the chance is created that an alternative theory might prevail. Therefore, the evolution of the associated entropy is a way to measure the degree of penetration of a conspiracy theory. Our general framework relies on online content made voluntarily available by crowds of people, in response to some news or blog articles published by official news agencies. We apply different aggregation levels (comment, person, discussion thread) and discuss the associated patterns of entropy change.Comment: 21 page, 14 figure
