Domiciliary Care: The Formal and Informal Labour Process

Domiciliary carers are paid care workers who travel to the homes of older people to assist with personal routines. Increasingly, over the past 20 years, the delivery of domiciliary care has been organised according to market principles and portrayed as the ideal type of formal care; offering cost savings to local authorities and independence for older people. Crucially, the work of the former ‘home help’ is transformed as domiciliary carers are now subject to the imperative of private, competitive accumulation which necessitates a constant search for increases in labour productivity. Drawing on qualitative data from domiciliary carers, managers and stakeholders, this article highlights the commodification of caring labour and reveals the constraints, contradictions and challenges of paid care work. Labour Process Theory offers a means of understanding the political economy of care work and important distinctions in terms of the formal and informal domiciliary care labour process

Real-time dynamic holographic image storage device

A real-time dynamic holographic image storage device uses four-wave mixing in a pair of photorefractive crystals. An oscillation is produced between the crystals which can be maintained indefinitely after the initial object beam is discontinued. The object beam produces an interference pattern in a first crystal to produce phase-conjugated object beam which is directed towards the second crystal. In the second crystal another interference pattern is created which produces a reconstructed object beam. The reconstructed object beam is directed back towards the first crystal. The interference patterns are produced by interaction of the object and phase-conjugated object beam with a read and write beam in each of the crystals. By manipulation of the ratio of the read and write beam intensities in at least one of the crystals, the phase-conjugate or reconstructed object beam output therefrom can be amplified to maintain stable oscillation between the two crystals
