Researching suicide, attempted suicide and near-lethal self-harm by offenders in community settings: Challenges for future research

Suicide is a serious international health problem and is more likely to occur in vulnerable populations such as offenders. There is an abundance of research into suicides of prisoners, but few studies have been carried out on suicides of offenders serving community sentences. This article identifies and evaluates the limited research that is available. Recommendations for future research are made, including how in-depth interviews can provide important information about near lethal incidents from the service users’ perspective, and how international comparisons could be helpful in understanding this problem further.

Adaptive self-calibrating image rejection receiver

An adaptive self-calibrating image rejection receiver is described, containing a modified Weaver image rejection mixer and a Digital Image Rejection Processor (DIRP). The blind source-separation-based DIRP eliminates the I/Q errors improving the Image Rejection Ratio (IRR) without the need for trimming or use of power-hungry discrete components. Hardware complexity is minimal, requiring only two complex coefficients; hence it can be easily integrated into the signal processing path of any receiver. Simulation results show that the proposed approach achieves 75-97 dB of IRR.

The role, organisation and contribution of community enterprise to urban regeneration policy in the UK

This monograph investigates the organisation, constitution and delivery of community-based organisations which are normally called community enterprises in the UK. These are organisations which emerge from local communities at the neighbourhood level, work in partnership with the public and private sectors, and provide a range of services to meet social, economic and environmental needs. The main focus of the paper is to explore how these organisations contribute to local regeneration strategies, generate social capital and contribute towards the promotion of civil society in general. The main emphasis is on organisations in England and Wales but comparisons are made with the USA and other countries where relevant literature is available. The key questions to be answered relate to the organisation and management of these bodies; the extent to which they engage with and contribute to local regeneration strategies; and the impact they have particularly in acquiring and managing assets. The diversity of the sector, and the range, scale and level of benefits it can deliver is illustrated through five detailed case studies of community enterprises established at different times, in different geographical locations and with different objectives and funding regimes. But, whilst the UK political economy is moving towards less state intervention and more community self-help, the community development corporations in the USA provide an indication of the future direction community enterprises might take in the UK as part of a broad trend towards civic capacity building.
