Do you want to bet? The prevalence of problem gambling amongst athletes in the UK
This presentation was given as part of the 2011 London Workshop on Problem Gambling: Theory and (Best) Practice by Dr Daniel Rhind from the Sports Sciences subject area at Brunel University. The workshop was organised by Professor Fernand Gobet and Dr Marvin Schiller and hosted by Brunel University on the 13th September 2011
Strong CP-Problem in Superstring Theory
We apply the solution for the strong CP-problem in the 4-dimensional
superstring theory recently proposed by Ibez and
Lst to Calabi-Yau type models and study its phenomenological
aspects. In Calabi-Yau type models there seem to be phenomenologically
difficult problems in the axion decoupling from the neutral gauge currents and
the compatibility between the proton stability and the cosmological bound on
the axion. DFSZ type invisible axion mechanism which works without heavy extra
colored fields may be more promising than KSVZ axion in the viewpoint of proton
stability.Comment: 11 pages, DPKU920
The Problem Of Gauge Theory
I sketch what it is supposed to mean to quantize gauge theory, and how this
can be made more concrete in perturbation theory and also by starting with a
finite-dimensional lattice approximation. Based on real experiments and
computer simulations, quantum gauge theory in four dimensions is believed to
have a mass gap. This is one of the most fundamental facts that makes the
Universe the way it is. This article is the written form of a lecture presented
at the conference "Geometric Analysis: Past and Future" (Harvard University,
August 27-September 1, 2008), in honor of the 60th birthday of S.-T. Yau
An Overdetermined Problem in Potential Theory
We investigate a problem posed by L. Hauswirth, F. H\'elein, and F. Pacard,
namely, to characterize all the domains in the plane that admit a "roof
function", i.e., a positive harmonic function which solves simultaneously a
Dirichlet problem with null boundary data, and a Neumann problem with constant
boundary data. Under some a priori assumptions, we show that the only three
examples are the exterior of a disk, a halfplane, and a nontrivial example. We
show that in four dimensions the nontrivial simply connected example does not
have any axially symmetric analog containing its own axis of symmetry.Comment: updated version. 20 pages, 3 figure
Moral Error Theory and the Belief Problem
Moral error theories claim that (i) moral utterances express moral beliefs, that (ii) moral beliefs ascribe moral properties, and that (iii) moral properties are not instantiated. Thus, according to these views, there seems to be conclusive evidence against the truth of our ordinary moral beliefs. Furthermore, many error theorists claim that, even if we accepted moral error theory, we could still in principle keep our first-order moral beliefs. This chapter argues that this last claim makes many popular versions of the moral error theory incompatible with the standard philosophical accounts of beliefs. Functionalism, normative theories of beliefs, representationalism, and interpretationalism all entail that being sensitive to thoughts about evidence is a constitutive feature of beliefs. Given that many moral error theorists deny that moral beliefs have this quality, their views are in a direct conflict with the most popular views about the nature of beliefs
