The phase-dependent linear conductance of a superconducting quantum point contact

The exact expression for the phase-dependent linear conductance of a weakly damped superconducting quantum point contact is obtained. The calculation is performed by summing up the complete perturbative series in the coupling between the electrodes. The failure of any finite order perturbative expansion in the limit of small voltage and small quasi-particle damping is analyzed in detail. In the low transmission regime this nonperturbative calculation yields a result which is at variance with standard tunnel theory. Our result predicts the correct sign of the quasi-particle pair interference term and exhibits an unusual phase-dependence at low temperatures in qualitative agreement with the available experimental data.Comment: 12 pages (revtex) + 1 postscript figure.

From prison to detention: the carceral trajectories of foreign-national prisoners in the United Kingdom

The United Kingdom has taken an increasingly punitive stance towards ‘foreign criminals’ using law and policy to pave the way for their expulsion from the country. Imprisonment, then, becomes the first stage in a complex process intertwining identity, belonging and punishment. We draw here on research data from two projects to understand the carceral trajectories of foreign-national offenders in the UK. We consider the lived experiences of male foreign-nationals in two sites: prison and immigration detention. The narratives presented show how imprisonment and detention coalesce within the deportation regime as a ‘double punishment’, one that is highly racialised and gendered. We argue that the UK’s increasingly punitive response to foreign-national offenders challenges the traditional purposes of punishment by sidestepping prisoners’ rehabilitative efforts and denying ‘second chances’ while enacting permanent exclusion through bans on re-entry

The role of oversight in foreign-national only prisons: counteracting the disapplication of rehabilitation

In several European countries, prisons have been created solely to house foreign national prisoners without leave to remain. Contrary to contemporary international human rights law and standards on prison management, there seems to be a trend towards the disapplication of rehabilitative theory and practice for this group of prisoners. In particular, they do not seem to receive the same preparation for release and reintegrative support as other prisoners. This paper explores the role international standards and oversight bodies have in upholding rehabilitation as the foundational objective for prison management in foreign national only prisons. It outlines the changes to the prison estate, policy and regime that have resulted from the increasing focus on removal within both the prison and penal process. The consequences of the disapplication of rehabilitation for prisons, prison officers, prisoners and society itself are analysed before the paper moves to examine the role oversight bodies could and should play in the protection of the rights of this vulnerable category of prisoner and the primacy that should be accorded to rehabilitative theory and practice. It concludes by asking whether such standards and oversight have inverted the panopticon by placing the trigger for international reactions in the hands of prisoners and NGOs

The area-based social patterning of injuries among 10 to 19 year olds Changes over time in the Stockholm County

<p>Abstract</p> <p>Background</p> <p>Area-based studies of childhood injuries strongly suggest that neighborhood socio-demographic and economic circumstances impact on various – though not all – types of injuries. The primary aim of this study was to investigate the stability over time of the association between area characteristics and childhood injuries of various causes.</p> <p>Methods</p> <p>Register-based and ecological, the study encompassed Stockholm County's 138 parishes, and considered two time periods (1993–95; 2003–05). Two indices were measured: economic deprivation and social fragmentation, and parishes were allocated to their respective quintile on each index. Data on both unintentional and intentional injuries for children (boys and girls) aged 10–14 and 15–19 respectively were gathered from the County Council's hospital inpatient register. For each period and index, gender, age and cause-specific comparisons were made to assess the rate ratios (with 95% confidence intervals) of being injured using parishes belonging to the best index level as a comparison group. A series of simple and partial Pearson correlations were also calculated to assess the independent contribution of each index.</p> <p>Results</p> <p>Regardless of time period, there were rather few significant rate ratios and, when they occurred, there were both under and excess risks. For instance, in each period, boys from both age groups living in parishes with the highest levels of economic deprivation had lower rate of injury as a motor vehicle rider. Most strikingly, intentional injuries were more frequent during the second time period and in considerable excess among girls aged 15–19 from more economically deprived areas. Also, during that last period, none of the injury causes correlated significantly with the index of social fragmentation after adjustment for economic deprivation (partial correlation).</p> <p>Conclusion</p> <p>Over a ten-year period, differential economic deprivation among parishes has widened more than social fragmentation in Stockholm County. The correlation between those indices is high in both periods of time whilst the association between the levels of each index and injury rates varies depending on group of injuries or time period considered. It is of concern that intentional injuries have increased numerically and are significantly and positively correlated with economic deprivation (net of social fragmentation), in particular among girls.</p
