Tackling concentrated worklessness: integrating governance and policy across and within spatial scales
Spatial concentrations of worklessness remained a key characteristic of labour markets in advanced industrial economies, even during the period of decline in aggregate levels of unemployment and economic inactivity evident from the late 1990s to the economic downturn in 2008. The failure of certain localities to benefit from wider improvements in regional and national labour markets points to a lack of effectiveness in adopted policy approaches, not least in relation to the governance arrangements and policy delivery mechanisms that seek to integrate residents of deprived areas into wider local labour markets. Through analysis of practice in the British context, we explore the difficulties of integrating economic and social policy agendas within and across spatial scales to tackle problems of concentrated worklessness. We present analysis of a number of selected case studies aimed at reducing localised worklessness and identify the possibilities and constraints for effective action given existing governance arrangements and policy priorities to promote economic competitiveness and inclusion
The pupil's response to affective pictures: Role of image duration, habituation, and viewing mode
The pupil has been shown to be sensitive to the emotional content of stimuli. We examined this phenomenon by comparing fearful and neutral images carefully matched in the domains of luminance, image contrast, image color, and complexity of content. The pupil was more dilated after viewing affective pictures, and this effect was (a) shown to be independent of the presentation time of the images (from 100â3,000 ms), (b) not diminished by repeated presentations of the images, and (c) not affected by actively naming the emotion of the stimuli in comparison to passive viewing. Our results show that the emotional modulation of the pupil is present over a range of variables that typically vary from study to study (image duration, number of trials, free viewing vs. task), and encourages the use of pupillometry as a measure of emotional processing in populations where alternative techniques may not be appropriate
The impact of the direct payment of housing benefit: evidence from Great Britain
In recent years, a number of welfare reforms have been introduced in the UK by Conservative-led governments. The most high profile of these is Universal Credit (UC), which is currently being rolled out across the country. A key feature of UC is a change in the way the income-related housing allowance for social housing tenants (Housing Benefit) is administered, as under UC, it is paid directly to tenants (direct payment), who are responsible for paying their rent. This represents a step change for them as for more than 30 years landlord payment has been the norm in the UK. There has been little research into direct payment. This paper seeks to address this gap in knowledge by presenting the key findings of an initiative designed to trial direct payment. It finds that many tenants experienced difficulties on direct payment. Reflecting this, landlords' arrears rose markedly
The New Deal: jeopardised by the geography of unemployment?
The New Deal is the Labour government's flagship programme to "end the tragic waste of youth and long-term unemployment" by getting people off welfare benefits and into work. This paper argues that the principal weakness of the New Deal is that it seeks to influence the character of labour supply (i.e. the motivation and skills of the unemployed) while neglecting the state of labour demand, which varies greatly between places. The uneven geography of unemployment in the UK is likely to have a crucial bearing on the programme's impact and effectiveness, but this has been largely ignored in its development. The paper outlines some of the practical consequences of this imbalance and suggests how it could be rectified for the programme to be more effective
Interpretation of radio continuum and molecular line observations of Sgr B2: free-free and synchrotron emission, and implications for cosmic rays
Recent ammonia (1,1) inversion line data on the Galactic star forming region
Sgr B2 show that the column density is consistent with a radial Gaussian
density profile with a standard deviation of 2.75 pc. Deriving a formula for
the virial mass of spherical Gaussian clouds, we obtain a virial mass of 1.9
million solar masses for Sgr B2. For this matter distribution, a reasonable
magnetic field and an impinging flux of cosmic rays of solar neighbourhood
intensity, we predict the expected synchrotron emission from the Sgr B2 giant
molecular cloud due to secondary electrons and positrons resulting from cosmic
ray interactions, including effects of losses due to pion production collisions
during diffusive propagation into the cloud complex.
We assemble radio continuum data at frequencies between 330 MHz and 230 GHz.
From the spectral energy distribution the emission appears to be thermal at
all frequencies. Before using these data to constrain the predicted synchrotron
flux, we first model the spectrum as free-free emission from the known ultra
compact HII regions plus emission from an envelope or wind with a radial
density gradient. This severely constrains the possible synchrotron emission by
secondary electrons to quite low flux levels. The absence of a significant
contribution by secondary electrons is almost certainly due to multi-GeV energy
cosmic rays being unable to penetrate far into giant molecular clouds. This
would also explain why 100 MeV--GeV gamma-rays (from neutral pion decay or
bremsstrahlung by secondary electrons) were not observed from Sgr B2 by EGRET,
while TeV energy gamma-rays were observed, being produced by higher energy
cosmic rays which more readily penetrate giant molecular clouds.Comment: 11 pages, 10 figures. New section on diffusion of primary and
secondary cosmic ray electrons into and within the Sgr B2 Giant Molecular
Cloud added. Main corrections to proofs made in this versio
'Treatment of the Sportsman's groin': British Hernia Society's 2014 position statement based on the Manchester Consensus Conference
<b>Introduction</b> The aim was to produce a multidisciplinary consensus to determine the current position on the nomenclature, definition, diagnosis, imaging modalities and management of Sportsman's groin (SG).<p></p>
<b>Methods</b> Experts in the diagnosis and management of SG were invited to participate in a consensus conference held by the British Hernia Society in Manchester, UK on 11â12 October 2012. Experts included a physiotherapist, a musculoskeletal radiologist and surgeons with a proven track record of expertise in this field. Presentations detailing scientific as well as outcome data from their own experiences were given. Records were made of the presentations with specific areas debated openly.<p></p>
<b>Results</b> The term âinguinal disruptionâ (ID) was agreed as the preferred nomenclature with the term âSportsman's herniaâ or âgroinâ rejected, as no true hernia exists. There was an overwhelming agreement of opinion that there was abnormal tension in the groin, particularly around the inguinal ligament attachment. Other common findings included the possibility of external oblique disruption with consequent small tears noted as well as some oedema of the tissues. A multidisciplinary approach with tailored physiotherapy as the initial treatment was recommended with any surgery involving releasing the tension in the inguinal canal by various techniques and reinforcing it with a mesh or suture repair. A national registry should be developed for all athletes undergoing surgery.<p></p>
<b>Conclusions</b> ID is a common condition where no true hernia exists. It should be managed through a multidisciplinary approach to ensure consistent standards and outcomes are achieved
Mapping Exoplanets
The varied surfaces and atmospheres of planets make them interesting places
to live, explore, and study from afar. Unfortunately, the great distance to
exoplanets makes it impossible to resolve their disk with current or near-term
technology. It is still possible, however, to deduce spatial inhomogeneities in
exoplanets provided that different regions are visible at different
times---this can be due to rotation, orbital motion, and occultations by a
star, planet, or moon. Astronomers have so far constructed maps of thermal
emission and albedo for short period giant planets. These maps constrain
atmospheric dynamics and cloud patterns in exotic atmospheres. In the future,
exo-cartography could yield surface maps of terrestrial planets, hinting at the
geophysical and geochemical processes that shape them.Comment: Updated chapter for Handbook of Exoplanets, eds. Deeg & Belmonte. 17

Observations of the Askaryan Effect in Ice
We report on the first observations of the Askaryan effect in ice: coherent
impulsive radio Cherenkov radiation from the charge asymmetry in an
electromagnetic (EM) shower. Such radiation has been observed in silica sand
and rock salt, but this is the first direct observation from an EM shower in
ice. These measurements are important since the majority of experiments to date
that rely on the effect for ultra-high energy neutrino detection are being
performed using ice as the target medium. As part of the complete validation
process for the Antarctic Impulsive Transient Antenna (ANITA) experiment, we
performed an experiment at the Stanford Linear Accelerator Center (SLAC) in
June 2006 using a 7.5 metric ton ice target, yielding results fully consistent
with theoretical expectations.Comment: 4 pages, 5 figures, minor correction
