Problems Prisoners Face in the Reentry Industry
Prison sentences vary depending on the crime committed. When sentences come to an end, prisoners return to society. Society does not just accept these prisoners back into everyday life with open arms. This paper explores the challenges incarcerated individuals experience when they reenter society after incarceration? The discussion focuses on the different challenges that these individuals face in their battle of entering back into society and being accepted by individuals in the communities they return to. Some key elements will focus on how reentry affects work, housing, rehabilitation and relationships

A review of the theoretical basis for bulk mass flux convective parameterization
Most parameterizations for precipitating convection in use today are bulk schemes, in which an ensemble of cumulus elements with different properties is modelled as a single, representative entraining-detraining plume. We review the underpinning mathematical model for such parameterizations, in particular by comparing it with spectral models in which elements are not combined into the representative plume. The chief merit of a bulk model is that the representative plume can be described by an equation set with the same structure as that which describes each element in a spectral model. The equivalence relies on an ansatz for detrained condensate introduced by Yanai et al. (1973) and on a simplified microphysics. There are also conceptual differences in the closure of bulk and spectral parameterizations. In particular, we show that the convective quasi-equilibrium closure of Arakawa and Schubert (1974) for spectral parameterizations cannot be carried over to a bulk parameterization in a straightforward way. Quasi-equilibrium of the cloud work function assumes a timescale separation between a slow forcing process and a rapid convective response. But, for the natural bulk analogue to the cloud-work function (the dilute CAPE), the relevant forcing is characterised by a different timescale, and so its quasi-equilibrium entails a different physical constraint. Closures of bulk parameterization that use the non-entraining parcel value of CAPE do not suffer from this timescale issue. However, the Yanai et al. (1973) ansatz must be invoked as a necessary ingredient of those closures
An analysis of the use of acute hospital resources, by the residents of Bexley and Greenwich
An analysis was conducted of the use of acute hospital resources by the residents of the two
Boroughs of Bexley and Greenwich. The data related to hospital episode statistics for
1996/97. The data set is able to capture all hospital admissions on a resident basis so is not
open to the bias that may result from looking just at service provision within the boundary of
the Health Authority
Surname studies with genetics
Genetic studies of surnames are briefly reviewed. In particular, such DNA studies can sometimes provide clues to a surname's meaning. A few surnames are being found to include unusually large single families, which are far more populous than computer simulations for monogamous families predict, suggesting that they might best be explained by their getting off to a fast start through polygyny or concubines: Brehon Law in Ireland and medieval Welsh Law were relatively accepting of polygyny. The Plant surname in the Welsh Marches largely comprises an abnormally large single family and this favours the Welsh meaning '[many] children', though various other meanings for this surname have been suggested. The surnames Meates, Meats, Mates, Mate and Myatt in north Staffordshire and Ireland belong to a single family and appear to have derived from the female forename Maiot

Comparison of stochastic parameterisation approaches in a single-column model
We discuss and test the potential usefulness of single-column models (SCMs) for the testing of stochastic physics schemes that have been proposed for use in general circulation models (GCMs). We argue that although single column tests cannot be definitive in exposing the full behaviour of a stochastic method in the full GCM, and although there are differences between SCM testing of deterministic and stochastic methods, SCM testing remains a useful tool. It is necessary to consider an ensemble of SCM runs produced by the stochastic method. These can be usefully compared to deterministic ensembles describing initial condition uncertainty and also to combinations of these (with structural model changes) into poor man's ensembles. The proposed methodology is demonstrated using an SCM experiment recently developed by the GCSS (GEWEX Cloud System Study) community, simulating transitions between active and suppressed periods of tropical convection
Study Bugs do a poster presentation
The poster describes the concepts behind, and the development of, a series of short films which deliver study skills information to students using an informal, imaginative and slightly quirky style. The stars of the films are the study bugs, who have taken on a life of their own, presenting important information in their own inimitable style. The videos have been used in teaching sessions, at Derby and other universities, to reinforce taught content and engage students in discussion. The films are available online through YouTube and can be embedded into VLEs. They have had positive feedback from academics and students. The films are accessible to students from different academic and cultural backgrounds, highlighting core concepts in a straightforward manner
ϱ → 4π in chirally symmetric models
The decays rho0 → 2π+2π− and rho0 → 2π0π+π− are studied using various effective Lagrangians for π and rho (and in some case a1) mesons, all of which respect the approximate chiral symmetry of the strong interaction. Partial widths of the order of 1 keV or less are found in all cases. These are an order of magnitude smaller than recent predictions based on non-chiral models
