Civil protective orders effective in stopping or reducing partner violence: challenges remain in rural areas with access and enforcement

Civil protective orders are a low cost, effective solution in either stopping or significantly reducing partner violence for women. While all women benefit from civil protective orders, this brief finds there are greater obstacles to enforcement in rural places, which result in less benefit for rural than urban women. The authors suggest that policies and services should be tailored to address community-specific barriers and differences such as hours of access, time it takes to obtain or serve an order, and access to information about the process

Black and minority ethnic sex offenders

In the past ten years or so there has been a growing concern that the treatment needs of Black and Minority Ethnic (BME) sex offenders in prison are not being appropriately met. Underpinning this concern is the continued under representation of BME sex offenders on the Sex Offender Treatment Programme (SOTP). Although some research has been undertaken into how BME prisoners experience the SOTP and in to its ostensible effectiveness with BME sex offenders, little is known about why the take-up of the SOTP is poor with this group. In this paper we first consider some specific demographic issues that need to be understood in order to reflect more widely on the BME sex offender in prison. We then summarise what is currently known about effective practice with this group, thereafter we consider, in turn, current provision for BME sex offenders in England and Wales and suggestions for developing practice with this group of men. However, before we turn to these issues, it is important to consider briefly issues of terminology. Terminologies in relation to ethnicities and race are fraught with conceptual difficulties. Aspinall has highlighted the limitations of ‘pan-ethnic’ groups, such as ‘BME’; such groupings are ‘statistical collectivities’ and ‘the groups thus defined will be nothing more than meaningless statistical collectivities that do not represent any of the constituent groups within the term.’ . However, at the outset of this paper we use the collective term BME - this term is currently used by a number of Government Departments in the UK, including the Prison Service. Later we suggest that a more sophisticated understanding of ethnic cultures may be necessary to develop practice with BME sex offenders.</p

Nucleosynthesis in Power-Law Cosmologies

We have recently considered cosmologies in which the Universal scale factor varies as a power of the age of the Universe and concluded that they cannot satisfy the observational constraints on the present age, the magnitude-redshift relation for SN Ia, and the primordial element (D, He3, He4, and Li7) abundances. This claim has been challenged in a proposal that suggested a high baryon density model (Omega_B*h*h = 0.3) with an expansion factor varing linearly with time could be consistent with the observed abundance of primoridal helium-4, while satisfying the age and magnitude-redshift constraints. In this paper we further explore primordial nucleosynthesis in generic power-law cosmologies, including the linear case, concluding that models selected to satisfy the other observational constraints are incapable of accounting for all the light element abundances.Comment: Matches version accepted for publication in Phys.

Development of inflatable structures at the University of Southampton

Inflatable technology for space applications is under continual development and advances in high strength fibres and rigidizable materials have pushed the limitations of these structures. This has lead to their application in deploying large-aperture antennas, reflectors and solar sails. However, many significant advantages can be achieved by combining inflatable structures with structural stiffeners such as tape springs. These advantages include control of the deployment path of the structure while it is inflating (a past weakness of inflatable structure designs), an increased stiffness of the structure once deployed and a reduction in the required inflation volume. Such structures have been previously constructed at the Jet Propulsion Laboratory focusing on large scale booms. However, due to the high efficiency of these designs they are also appealing to small satellite systems. This article outlines ongoing research work performed at the University of Southampton into the field of small satellite hybrid inflatable structures. Inflatable booms have been constructed and combined with tape spring reinforcements to create simple hybrid structures. These structures have been subjected to bending tests and compared directly to an equivalent inflatable tube without tape spring reinforcement. This enables the stiffness benefits to be determined with respect to the added mass of the tape springs. The paper presents these results, which leads to an initial performance assessment of these structures

Evolution of hairpin vortices in a shear flow

Recent experimental studies suggest that the hairpin vortex plays an important (and perhaps dominant) role in the dynamics of turbulent flows near walls. In this study a numerical procedure is developed to allow the accurate computation of the trajectory of a 3-D vortex having a small core radius. For hairpin vortices which are convected in a shear flow above a wall, the calculated results show that a 2-D vortex containing a small 3-D disturbance distorts into a complex shape with subsidiary hairpin vortices forming outboard of the original hairpin vortex. As the vortex moves above the wall, it induces unsteady motion in the viscous flow near the wall: numerical solutions suggest that the boundary-layer flow near the wall will ultimately erupt in response to the motion of the hairpin vortex and in the process a secondary hairpin vortex will be created. The computer results agree with recent experimental investigations

Modelling self-piercing riveted joint failures in automotive crash structures

This paper describes a new model and method to predict Self-Piercing Riveted (SPR) joint interlock failures in aluminium sheet at crash speeds using explicit finite element simulation. SPR interlock failure is dependent on rivet direction, which is included in the model. A mesh independent approach is adopted for connection model which is capable of industrial application at the full vehicle crash analysis level. The paper provides an overview of the approach to validate connection model; typically by developing detailed physics based models of various joint configurations supported with high speed experimental data, through to model capable of industrial application. The framework to validate connection model for use in crash simulation tools is expected to have broader applicatio
