    Communities of Designers: Transforming a Situation into a Unified Whole

    A new player, digital technology, has entered into the already variegated and often contentious world of teaching and teacher education. This new player promises to disrupt existing practices in some as yet undefined way. It is not surprising that its eventual impact on learning or on educational equity is uncertain, when there is still great uncertainty around basic questions such as which digital tools ought to be considered or what they cost. The previous chapters in this book make a major contribution to the conversation about (digital) technology in education. They address three large questions: How should we integrate technology into learning? What happens when we do? How do we learn to do it (possibly better than before)?published or submitted for publicationnot peer reviewe

    Lagrangian versus Quantization

    We discuss examples of systems which can be quantized consistently, although they do not admit a Lagrangian description.Comment: 8 pages, no figures; small corrections, references adde

    Mapping the First 10 Years with Leximancer: Themes and Concepts in the Sports Management International Journal Choregia

    This study uses Leximancer (a text-mining tool for visualizing the structure of concepts and themes in text) to map the published research within Sports Management International Journal Choregia from 2005 to 2014. Drawing on 88 papers, of which 61 were classified as empirical and 27 as non-empirical ones, results reveal that the last half of the examined period concerned works that do not relate to the Greek context, which has been the case during the first years of Choregia’s publication. ‘Sports participation’, ‘physical activity’, ‘Greek football clubs’ – all largely associated with ‘management’ and ‘factors’ – shape the main themes in the studies published within Choregia. In addition, an emphasis on positivistic approaches, through the employment of questionnaires and utilizing students as the population for data collection, appears to be the dominant methodological orientation of the published content in Choregia. Becoming the platform for studies that originate beyond the American, Greek, and Iranian contexts, through special issues and invited contributions in the form of research notes would potentially increase this outlet’s scope and depth (that is, context and themes, respectively)

    An Evolutionary Theory of Inflation Inertia

    Get PDF
    We provide a simple theory of inflation inertia in a staggered price setting framework a la Calvo (1983). Contrary to Calvo's formulation, the frequency of price changes is allowed to vary according to an evolutionary criterion. Inertia is the direct result of gradual adjustment in this frequency following a permanent change in the rate of money growth.Inflation inertia, evolutionary game theory, staggered price setting,

    Lessons from the Bakken Oil Patch

    This is a preprint of an article that appeared in the Journal Contemporary Archaeology. The article summarizes the recent work of the North Dakota Man Camp Project to understand the largely undocumented migrants arriving in the Bakken Oil Patch for work. It argues that efforts to document short-term labor in the Bakken exposes particular challenges facing the archaeology of the modern world ranging from the ephemerality of short-term settlements to the hyper-abundance of modern objects. The use of photography, video, interviews, and descriptions produced an abundant archive of archaeological ephemera that in some ways parallels the modern character of temporary workforce housing. The final section of this article offers some perspectives on how work in the Bakken oil patch can inform policy, our understanding of material culture in the modern world, and the role of the discipline in forming a shared narrative
