    Approaches to Open Access in Scientific Publishing

    Full text link
    Approaches to scientific journal publishing that provide free access to all readers are challenging the standard subscription-based model. But in domains that have a well-functioning system of publicly accessible preprint repositories like arXiv, Open Access is already effectively available. In physics, such repositories have long coexisted constructively with refereed, subscription based journals. Trying to replace this by a system based on journals whose revenue is derived primarily from fees charged to authors is unlikely to provide a better guarantee of Open Access, and may be in conflict with the maintenance of high quality standards.Comment: 5 pages.

    The Immediate Practical Implication of the Houghton Report: Provide Green Open Access Now

    Among the many important implications of Houghton et al’s (2009) timely and illuminating JISC analysis of the costs and benefits of providing free online access (“Open Access,” OA) to peer-reviewed scholarly and scientific journal articles one stands out as particularly compelling: It would yield a forty-fold benefit/cost ratio if the world’s peer-reviewed research were all self-archived by its authors so as to make it OA. There are many assumptions and estimates underlying Houghton et al’s modelling and analyses, but they are for the most part very reasonable and even conservative. This makes their strongest practical implication particularly striking: The 40-fold benefit/cost ratio of providing Green OA is an order of magnitude greater than all the other potential combinations of alternatives to the status quo analyzed and compared by Houghton et al. This outcome is all the more significant in light of the fact that self-archiving already rests entirely in the hands of the research community (researchers, their institutions and their funders), whereas OA publishing depends on the publishing community. Perhaps most remarkable is the fact that this outcome emerged from studies that approached the problem primarily from the standpoint of the economics of publication rather than the economics of research

    Multispecies quantum Hurwitz numbers

    The construction of hypergeometric 2D Toda τ\tau-functions as generating functions for quantum Hurwitz numbers is extended here to multispecies families. Both the enumerative geometrical significance of these multispecies quantum Hurwitz numbers as weighted enumerations of branched coverings of the Riemann sphere and their combinatorial significance in terms of weighted paths in the Cayley graph of SnS_n are derived.Comment: 11 pages.This is the revised version posted March 30, 201
