    Our door is always open : Aligning Literacy LearningPractices in Writing Programs and Residential LearningCommunities

    Get PDF
    Writing studies has considered college students\u27 literacy development as a chronological progression and as influenced by their off-campus connections to various cultural and professional communities. This project considers students\u27 literacy development across disciplines and university activity systems in which they\u27re simultaneously involved to look at the (missed) opportunities for fostering transfer across writing courses and residential learning communities as parallel—but rarely coordinated—high-impact practices. Rather than calling for the development of additional programs, I argue for building/strengthening connections between these existing programs by highlighting shared learning outcomes focused on literacy skills development and learning how to learn

    Who Learns from Collaborative Digital Projects? Cultivating Critical Consciousness and Metacognition to Democratize Digital Literacy Learning

    Get PDF
    Collaborative group work is common in writing classrooms, especially ones assigning digital projects. While a wealth of scholarship theorizes collaboration and advocates for specific collaborative pedagogies, writing studies has yet to address the ways in which privilege tied to race, gender, class, and other identity characteristics replicates itself within student groups by shaping the responsibilities individual group members assume, thereby affecting students\u27 opportunities for learning. Such concerns about equity are especially pressing where civically and professionally valuable twenty-first century digital literacies are concerned. This article uses theories of cultural capital and the participation gap to (1) analyze role uptake in case studies of diverse student groups and (2) suggest ways to expand writing studies\u27 current use of metacognition to address such inequities

    Characterization of the anticipated synchronization regime in the coupled FitzHugh--Nagumo model for neurons

    Get PDF
    We characterize numerically the regime of anticipated synchronization in the coupled FitzHugh-Nagumo model for neurons. We consider two neurons, coupled unidirectionally (in a master-slave configuration), subject to the same random external forcing and with a recurrent inhibitory delayed connection in the slave neuron. We show that the scheme leads to anticipated synchronization, a regime in which the slave neuron fires the same train of pulses as the master neuron, but earlier in time. We characterize the synchronization in the parameter space (coupling strength, anticipation time) and introduce several quantities to measure the degree of synchronization.Comment: 8 pages.

    Tagging, Folksonomy & Co - Renaissance of Manual Indexing?

    Get PDF
    This paper gives an overview of current trends in manual indexing on the Web. Along with a general rise of user generated content there are more and more tagging systems that allow users to annotate digital resources with tags (keywords) and share their annotations with other users. Tagging is frequently seen in contrast to traditional knowledge organization systems or as something completely new. This paper shows that tagging should better be seen as a popular form of manual indexing on the Web. Difference between controlled and free indexing blurs with sufficient feedback mechanisms. A revised typology of tagging systems is presented that includes different user roles and knowledge organization systems with hierarchical relationships and vocabulary control. A detailed bibliography of current research in collaborative tagging is included.Comment: Preprint. 12 pages, 1 figure, 54 reference

    Binary Evolution Constraints from Luminosity Functions of LMXBs

    Full text link
    The formation and evolution of low-mass X-ray binaries (LMXBs) is not well understood. The properties of a population of LMXBs depend on a number of uncertain aspects of binary evolution, and population studies offers a relatively new way of probing binary interactions. We have studied the shape of the faint end of the X-ray luminosity function (LF) of LMXBs in nearby galaxies with Chandra and in the Milky Way using the Swift all-sky monitor. We find a clear difference between the LF of LMXBs in globular clusters (GCs) and those outside, with a relative lack of faint GC sources. This indicates a difference in the composition of the two populations.Comment: Conference Proceedings for the International Conference on Binaries, Mykonos, Greec

    NCAR Arts Vibrancy Index: Hotbeds of America's Arts and Culture

    Get PDF
    What factors make up a community's arts vibrancy, and which cities possess them? While the complex mixture of attributes is a large puzzle to piece together, it is increasingly sought after by civic leaders, funders and policy makers. As a contribution to this growing interest, we have undertaken an analytical assessment of arts vibrancy across U.S. cities and developed the Arts Vibrancy Index, a set of data-based indices that highlight metropolitan areas whose arts and culture scenes pulsate with vigor and activity in a variety of ways

    The Effect of Finite Element Discretisation on the Stationary Distribution of SPDEs

    Full text link
    This article studies the effect of discretisation error on the stationary distribution of stochastic partial differential equations (SPDEs). We restrict the analysis to the effect of space discretisation, performed by finite element schemes. The main result is that under appropriate assumptions the stationary distribution of the finite element discretisation converges in total variation norm to the stationary distribution of the full SPDE.Comment: 15 pages, 1 figur
