Housing professionalism in the United Kingdom: the final curtain or a new age?
The unusually large, predominantly municipal, housing sector in the UK has provided the context for a large occupational grouping of "housing managers" that has claimed professional status. However, within the post-1945 British welfare state this professional project enjoyed limited success and social housing remained a fragile professional domain. This article explores the consequences for housing professionalism of the recent displacement of the bureau-professional "organisational settlement" by that characterising an emerging "managerial state". Managerialism constitutes a clear challenge to established forms of "professionalism", especially a weak profession such as housing management. However, professionalism is temporally and culturally plastic. Hence, the demands of managerialism, within the specific context of New Labour's quest for "community" cohesion, may be providing opportunities for a new urban network professionalism founded on claims to both generic and specific skills and also a knowledge base combining abstraction with local concreteness. The prominence in these networks of erstwhile "housing" practitioners may become the basis for a new, quite different, professional project. This argument is developed through both conceptual exploration and reference to empirical research. The latter involves reference to recent work by the authors on, first, the perception of housing employers of the changing nature and demands of "housing" work and its consequences for professionalism and, secondly, the professional project implications of the increasing prominence of neighbourhood management.</p
On Type IIA geometries dual to N = 2 SCFTs
We provide explicit solutions of Type IIA supergravity which are believed to
be dual to N = 2 superconformal four dimensional gauge theories. These explicit
solutions are based on the general ansatz for such a type of backgrounds
introduced by Gaiotto and Maldacena.Comment: 23 pages, 10 figures; minor corrections, references correcte
Absolute profinite rigidity and hyperbolic geometry
We construct arithmetic Kleinian groups that are profinitely rigid in the
absolute sense: each is distinguished from all other finitely generated,
residually finite groups by its set of finite quotients. The Bianchi group
with is rigid in
this sense. Other examples include the non-uniform lattice of minimal co-volume
in and the fundamental group of the Weeks manifold
(the closed hyperbolic -manifold of minimal volume).Comment: v2: 35 pages. Final version. To appear in the Annals of Mathematics,

To sell or not to sell? Behavior of shareholders during price collapses
It is a common belief that the behavior of shareholders depends upon the
direction of price fluctuations: if prices increase they buy, if prices
decrease they sell. That belief, however, is more based on ``common sense''
than on facts. In this paper we present evidence for a specific class of
shareholders which shows that the actual behavior of shareholders can be
markedly different.Comment: 9 pages, 1 figure. To appear in International Journal of Modern

Discovery of a Magnetic DZ White Dwarf with Zeeman-Split Lines of Heavy Elements
A spectroscopic survey of previously-unstudied Luyten Half Second proper
motion stars has resulted in the discoveries of two new cool magnetic white
dwarfs. One (LHS 2273) is a routine DA star, T= 6,500K, with Zeeman-split H
alpha and H beta, for which a simple model suggests a polar field strength of
18.5 MG viewed close to equator-on. However, the white dwarf LHS 2534 proves to
be the first magnetic DZ showing Zeeman-split Na I and Mg I components, as well
as Ca I and Ca II lines for which Zeeman components are blended. The Na I
splittings result in a mean surface field strength estimate of 1.92 MG. Apart
from the magnetic field, LHS 2534 is one of the most heavily-blanketed and
coolest DZ white dwarfs at T ~ 6,000K.Comment: 7 pages, Astrophysical Journal (Letters), in pres
Dynamical preparation of EPR entanglement in two-well Bose-Einstein condensates
We propose to generate Einstein-Podolsky-Rosen (EPR) entanglement between
groups of atoms in a two-well Bose-Einstein condensate using a dynamical
process similar to that employed in quantum optics. The local nonlinear S-wave
scattering interaction has the effect of creating a spin squeezing at each
well, while the tunneling, analogous to a beam splitter in optics, introduces
an interference between these fields that results in an inter-well
entanglement. We consider two internal modes at each well, so that the
entanglement can be detected by measuring a reduction in the variances of the
sums of local Schwinger spin observables. As is typical of continuous variable
(CV) entanglement, the entanglement is predicted to increase with atom number,
and becomes sufficiently strong at higher numbers of atoms that the EPR paradox
and steering non-locality can be realized. The entanglement is predicted using
an analytical approach and, for larger atom numbers, stochastic simulations
based on truncated Wigner function. We find generally that strong tunnelling is
favourable, and that entanglement persists and is even enhanced in the presence
of realistic nonlinear losses.Comment: 15 pages, 19 figure
Effects of Unstable Dark Matter on Large-Scale Structure and Constraints from Future Surveys
In this paper we explore the effect of decaying dark matter (DDM) on
large-scale structure and possible constraints from galaxy imaging surveys. DDM
models have been studied, in part, as a way to address apparent discrepancies
between the predictions of standard cold dark matter models and observations of
galactic structure. Our study is aimed at developing independent constraints on
these models. In such models, DDM decays into a less massive, stable dark
matter (SDM) particle and a significantly lighter particle. The small mass
splitting between the parent DDM and the daughter SDM provides the SDM with a
recoil or "kick" velocity vk, inducing a free-streaming suppression of matter
fluctuations. This suppression may be probed via weak lensing power spectra
measured by a number of forthcoming imaging surveys that aim primarily to
constrain dark energy. Using scales on which linear perturbation theory alone
is valid (multipoles < 300), surveys like Euclid or LSST can be sensitive to vk
> 90 km/s for lifetimes ~ 1-5 Gyr. To estimate more aggressive constraints, we
model nonlinear corrections to lensing power using a simple halo evolution
model that is in good agreement with numerical simulations. In our most
ambitious forecasts, using multipoles < 3000, we find that imaging surveys can
be sensitive to vk ~ 10 km/s for lifetimes < 10 Gyr. Lensing will provide a
particularly interesting complement to existing constraints in that they will
probe the long lifetime regime far better than contemporary techniques. A
caveat to these ambitious forecasts is that the evolution of perturbations on
nonlinear scales will need to be well calibrated by numerical simulations
before they can be realized. This work motivates the pursuit of such a
numerical simulation campaign to constrain dark matter with cosmological weak
lensing.Comment: 15 pages, 7 figures. Submitted to PR
Understanding the role of shame and its consequences in female hypersexual behaviours: A pilot study
Background and aims:
Hypersexuality and sexual addiction among females is a little understudied phenomenon. Shame is thought to be intrinsic to hypersexual behaviours, especially in women. Therefore, the aim of this study was to understand both hypersexual behaviours and consequences of hypersexual behaviours and their respective contributions to shame in a British sample of females (n = 102).
Methods:
Data were collected online via Survey Monkey.
Results:
Results showed the Sexual Behaviour History (SBH) and the Hypersexual Disorder Questionnaire (HDQ) had significant positive correlation with scores on the Shame Inventory. The results indicated that hypersexual behaviours (HBI and HDQ) were able to predict a small percentage of the variability in shame once sexual orientation (heterosexual vs. non-heterosexual) and religious beliefs (belief vs. no belief) were controlled for. Results also showed there was no evidence that religious affiliation and/or religious beliefs had an influence on the levels of hypersexuality and consequences of sexual behaviours as predictors of shame.
Conclusions:
While women in the UK are rapidly shifting to a feminist way of thinking with or without technology, hypersexual disorder may often be misdiagnosed and misunderstood because of the lack of understanding and how it is conceptualised. The implications of these findings are discussed
