    © 2016. The American Astronomical Society. All rights reserved.We present DES14X3taz, a new hydrogen-poor superluminous supernova discovered by the Dark Energy Survey supernova program, with additional photometric data provided by the Survey Using DECam for Superluminous Supernovae. Spectra obtained using Optical System for Imaging and low-Intermediate-Resolution Integrated Spectroscopy on the Gran Telescopio CANARIAS show DES14X3taz is an SLSN-I at z = 0.608. Multi-color photometry reveals a do…Read more

    Rorty and Tolerance
    Theoria 50 (101): 94-108. 2003.
    While Richard Rorty's general views on truth, objectivity, and relativism continue to attract much attention from professional philosophers, some of his contributions to ethical theory have thus far been remarkably neglected. In other work, I have begun the task of sketching what a Rortyan approach to traditional questions in meta-ethics might look like.1 Here, however, I shall attempt to summarize and evaluate some of the contributions that Rorty has made to important debates in first-order nor…Read more

    Environmental Rights in a Welfare State? A Comment on DeMerieux
    Oxford Journal of Legal Studies 23 (1): 111-125. 2003.
    The derivation of a category of ‘environmental rights’ (as argued in this journal by Margaret DeMerieux) from certain cases heard in the European Court of Human Rights is examined. Opposing the majority judicial opinion of that court, there is emerging a dissenting view which is reluctant to extend a rights perspective to those nuisances which can, in theory, be avoided by relocation of the family home. This critique is then extended to Marcic v Thames Water Utilities in which the claimant used …Read more

    We say that E is R-sparse if f(Ek) has no interior, for each k 2 N and f : Rk ! R de nable in R. (Throughout, \de nable" means \de nable without parameters".) In this note, we consider the extent to which basic metric and topological properties of subsets of R de nable in (R;E)# are determined by the corresponding properties of subsets of R de nable in (R;E), when R is an o-minimal expansion of (R;
