Low-level support for socially isolated older people: An evaluation of telephone befriending

In May 2005 Help the Aged and Zurich Community Trust launched a two year national programme ‘A Call in Time’. The purpose of the programme was to provide low level support and befriending services via the telephone to older people who are lonely, isolated or vulnerable. Eight projects were funded across the country. Following the launch of the programme, Help the Aged commissioned the Centre for Health Promotion Research at Leeds Metropolitan University to undertake an evaluation of the programme and to investigate the direct impact of low level support on older people who are vulnerable, isolated or lonely using the telephone as a specific tool of befriending. The main objectives of the evaluation were to: * Measure and identify the effectiveness of telephone befriending services for older people with regards to their mental and physical well-being and their quality of life and the extent to which services were of preventive value. * Examine the components parts of each model of telephone befriending and identify ‘models of good practice’. All eight telephone befriending schemes functioning within a variety of different parameters were included in the evaluation. The participants in this research included project co-ordinators, project volunteers and older people who were in receipt of the services

The use of telephone befriending in low level support for socially isolated older people--an evaluation.

There is increasing policy recognition that the alleviation of social isolation and loneliness in older people should be prioritised. Recently, technology, such as telephone networks and the Internet, has received attention in supporting isolated and lonely older people. Despite lack of evidence, telephone befriending has been considered an effective low-level method to decrease loneliness among older people. This study evaluated the impact of a national befriending scheme for isolated and/or lonely older people, involving eight project sites across the UK 2007-2008. The purpose was to assess the impact of different models of telephone-based befriending services on older people's health and well-being. A mixed methods approach was used. This paper reports on the findings from 40 in-depth interviews with older service recipients. The most important finding was that the service helped older people to gain confidence, re-engage with the community and become socially active again. Three topics were identified: why older people valued the service, what impact it had made on their health and well-being and what they wanted from the service. In addition, nine subthemes emerged: life is worth living, gaining a sense of belonging, knowing they had a friend, a healthy mind is a healthy body, the alleviation of loneliness and anxiety, increased self-confidence, ordinary conversation, a trusted and reliable service, the future--giving something back. In conclusion, the findings present in-depth qualitative evidence of the impact of telephone befriending on older people's well-being. Befriending schemes provide low-cost means for socially isolated older people to become more confident and independent and develop a sense of self-respect potentially leading to increased participation and meaningful relationships

Helium ion microscopy and energy selective scanning electron microscopy – two advanced microscopy techniques with complementary applications

Both scanning electron microscopes (SEM) and helium ion microscopes (HeIM) are based on the same principle of a charged particle beam scanning across the surface and generating secondary electrons (SEs) to form images. However, there is a pronounced difference in the energy spectra of the emitted secondary electrons emitted as result of electron or helium ion impact. We have previously presented evidence that this also translates to differences in the information depth through the analysis of dopant contrast in doped silicon structures in both SEM and HeIM. Here, it is now shown how secondary electron emission spectra (SES) and their relation to depth of origin of SE can be experimentally exploited through the use of energy filtering (EF) in low voltage SEM (LV-SEM) to access bulk information from surfaces covered by damage or contamination layers. From the current understanding of the SES in HeIM it is not expected that EF will be as effective in HeIM but an alternative that can be used for some materials to access bulk information is presented

Tunable reflection minima of nanostructured antireflective surfaces

Broadband antireflection schemes for silicon surfaces based on the moth-eye principle and comprising arrays of subwavelength-scale pillars are applicable to solar cells, photodetectors, and stealth technologies and can exhibit very low reflectances. We show that rigorous coupled wave analysis can be used to accurately model the intricate reflectance behavior of these surfaces and so can be used to explore the effects of variations in pillar height, period, and shape. Low reflectance regions are identified, the extent of which are determined by the shape of the pillars. The wavelengths over which these low reflectance regions operate can be shifted by altering the period of the array. Thus the subtle features of the reflectance spectrum of a moth-eye array can be tailored for optimum performance for the input spectrum of a specific application

Suppression of backscattered diffraction from sub-wavelength ‘moth-eye’ arrays

The eyes and wings of some species of moth are covered with arrays of nanoscale features that dramatically reduce reflection of light. There have been multiple examples where this approach has been adapted for use in antireflection and antiglare technologies with the fabrication of artificial moth-eye surfaces. In this work, the suppression of iridescence caused by the diffraction of light from such artificial regular moth-eye arrays at high angles of incidence is achieved with the use of a new tiled domain design, inspired by the arrangement of features on natural moth-eye surfaces. This bio-mimetic pillar architecture contains high optical rotational symmetry and can achieve high levels of diffraction order power reduction. For example, a tiled design fabricated in silicon and consisting of domains with 9 different orientations of the traditional hexagonal array exhibited a ~96% reduction in the intensity of the ?1 diffraction order. It is suggested natural moth-eye surfaces have evolved a tiled domain structure as it confers efficient antireflection whilst avoiding problems with high angle diffraction. This combination of antireflection and stealth properties increases chances of survival by reducing the risk of the insect being spotted by a predator. Furthermore, the tiled domain design could lead to more effective artificial moth-eye arrays for antiglare and stealth applications
