Shared practice, learning, and goals between police and young people: a qualitative analysis of the National Volunteer Police Cadets

Engaging all members of the public is of paramount importance to British policing. This assists with demystifying the role of police in society, and also providing a shared vision and partnership between communities and the criminal justice system. The National VPC programme provides the opportunity to achieve this, recruiting diverse young people into a structured programme led by a range of police officers and staff. A series of focus groups were conducted across the country with both cadets and adult leaders to explore the benefits of the cadet programme for both groups—those relevant to policing but also more widely for community cohesion and individual development. Although the benefits to policing were clearly articulated, a range of strengths to the programme were also identified

Self-Reported Strengths and Weaknesses in the Prediction of Institutional Aggression

Aggression on inpatient psychiatric units poses a multitude of issues not only for patients, but also for staff. Thus, the identification of dynamic risk factors that may increase and also of protective factors that may decrease the likelihood of a patient becoming aggressive is important. The current study sought to expand on the current literature by examining if there is a difference between self-perceived strengths and risk factors between aggressive and nonaggressive patients. More specifically, it was hypothesized that self-reported strengths would moderate the relationship between self-reported risk factors and institutional aggression (IA) in forensic and in civil psychiatric units at a state hospital. It was also hypothesized that patients from the forensic unit, or those transferred from the forensic to civil unit, would be more likely to engage in IA. To test these hypotheses, archival data were examined in a final sample of 300 participants. Findings revealed that when someone had at least one aggressive act, he or she was more likely to have reported at least one severe symptom or poor coping skill. However, further analysis revealed that self-reported protective factors, namely activities of daily living and cultural and religious considerations, did not moderate the relationship between self-reported risk factors, namely severe symptoms and poor coping, and IA. Finally, forensic patients were not found to be more likely to engage in IA. Low base rates are inherent to this area of research, thus future researchers might benefit from addressing this issue. Other suggestions for future research include the consideration of environmental factors specific to inpatient units that may have a direct impact on IA. Finally, it may be useful to use a valid and reliable measure to obtain self-reported risk and protective factors, which may improve the quality of findings

Temperature dependence of density profiles for a cloud of non-interacting fermions moving inside a harmonic trap in one dimension

We extend to finite temperature a Green's function method that was previously proposed to evaluate ground-state properties of mesoscopic clouds of non-interacting fermions moving under harmonic confinement in one dimension. By calculations of the particle and kinetic energy density profiles we illustrate the role of thermal excitations in smoothing out the quantum shell structure of the cloud and in spreading the particle spill-out from quantum tunnel at the edges. We also discuss the approach of the exact density profiles to the predictions of a semiclassical model often used in the theory of confined atomic gases at finite temperature.Comment: 7 pages, 4 figure

Spectral Equivalence of Bosons and Fermions in One-Dimensional Harmonic Potentials

Recently, Schmidt and Schnack (cond-mat/9803151, cond-mat/9810036), following earlier references, reiterate that the specific heat of N non-interacting bosons in a one-dimensional harmonic well equals that of N fermions in the same potential. We show that this peculiar relationship between specific heats results from a more dramatic equivalence between bose and fermi systems. Namely, we prove that the excitation spectrums of such bose and fermi systems are spectrally equivalent. Two complementary proofs are provided, one based on an analysis of the dynamical symmetry group of the N-body system, the other using combinatoric analysis.Comment: Six Pages, No Figures, Submitted to Phys.

Limits to Sympathetic Evaporative Cooling of a Two-Component Fermi Gas

We find a limit cycle in a quasi-equilibrium model of evaporative cooling of a two-component fermion gas. The existence of such a limit cycle represents an obstruction to reaching the quantum ground state evaporatively. We show that evaporatively the \beta\mu ~ 1. We speculate that one may be able to cool an atomic fermi gas further by photoassociating dimers near the bottom of the fermi sea.Comment: Submitted to Phys. Rev

Superfluidity in the interior-gap states

We investigate superfluidity in the interior-gap states proposed by Liu and Wilczek. At weak coupling, we find the {\em gapless} interior-gap state unstable in physically accessible regimes of the parameter space, where the superfluid density is shown to be always negative. We therefore conclude that the spatially-uniform interior-gap phase is extremely unstable unless it is fully gapped; in this case, however, the state is rather similar to conventional BCS states.Comment: To appear in Physical Review
