Emotional well-being in people with sight loss: Lessons from the grey literature
Literature that is not peer-reviewed and distributed through a publisher is known as ‘grey’. As it is used to inform policy and practice we reviewed the grey literature concerning emotional well-being in people with sight loss. We consulted and searched the websites of UK voluntary organizations, and scanned reference lists of previous reviews for reports available from 2001 to 2008. We summarized 24 studies in two sections: observations that assessed psychosocial well-being or demand for support services (n = 15); and evaluations of interventions that aimed to improve emotional well-being (n = 9). Observations showed that people with sight loss can report low emotional well-being, but their statistical and clinical significance requires testing. Interventions showed promise for counselling but also require further evaluation. We encourage service providers and researchers to collaborate and produce high quality research to more persuasively inform policy and practice
Wearable device to assist independent living.
Older people increasingly want to remain living independently in their own homes. The aim of the ENABLE project is to develop a wearable device that can be used both within and outside of the home to support older people in their daily lives and which can monitor their health status, detect potential problems, provide activity reminders and offer communication and alarm services. In order to determine the specifications and functionality required for development of the device user surveys and focus groups were undertaken and use case analysis and scenario modeling carried out. The project has resulted in the development of a wrist worn device and mobile phone combination that can support and assist older and vulnerable wearers with a range of activities and services both inside and outside of their homes. The device is currently undergoing pilot trials in five European countries. The aim of this paper is to describe the ENABLE device, its features and services, and the infrastructure within which it operates
The role of subjective social status in living well for carers of people with dementia: findings from the Improving the experience of Dementia and Enhancing Active Life (IDEAL) programme
YesWe investigated how carers of people with dementia evaluate their standing in their community and wider society, and if this is related to ‘living well’. We used baseline data from the Improving the experience of Dementia and Enhancing Active Life programme and found that carers rated their standing in society higher than in their local community. Higher evaluations of both were associated with enhanced life satisfaction, well-being and quality of life. Initiatives that increase support or engagement in the community or wider society may help to increase carers’ perceptions of their social status, enhancing their ability to ‘live well’.The IDEAL study was funded jointly by the Economic and Social Research Council (ESRC) and the National Institute for Health Research (NIHR) through grant ES/L001853/2. The ESRC is part of UK Research and Innovation (UKRI). ‘Improving the experience of Dementia and Enhancing Active Life: a longitudinal perspective on living well with dementia.

Properties of the Fixed Point Lattice Dirac Operator in the Schwinger Model
We present a numerical study of the properties of the Fixed Point lattice
Dirac operator in the Schwinger model. We verify the theoretical bounds on the
spectrum, the existence of exact zero modes with definite chirality, and the
Index Theorem. We show by explicit computation that it is possible to find an
accurate approximation to the Fixed Point Dirac operator containing only very
local couplings.Comment: 38 pages, LaTeX, 3 figures, uses style [epsfig], a few comments and

Perspectives of minority ethnic caregivers of people with dementia interviewed as part of the IDEAL programme
YesPostwar migrants from the Caribbean and Indian subcontinent (Bangladesh, India, and Pakistan) to the UK are now experiencing the onset of age-related diseases such as dementia. Our evidence base, both quantitative and qualitative, documenting the experiences of family caregivers of people with dementia is largely drawn from studies undertaken with white European, North American, and Australasian populations. Consequently, there is a need for research in the field of dementia caregiving to reflect the increasing diversity in ethnic identities of the older adult population of the UK. Using semistructured interviews, we investigated the experiences of 18 caregivers of people with dementia in Black Caribbean, Black African, and South Asian (Indian, Pakistani, and Bangladeshi) communities in England. Participants were recruited from the Join Dementia Research platform and were predominantly female intergenerational carers. We identified the following three themes: motivation to care (spending time with the care recipient and reciprocity), positive and negative consequences of caregiving (rewards and consequences), and the cultural context of caregiving (cultural norms and values supporting caregiving and negative attitudes towards dementia). Our findings develop existing literature by identifying (a) the importance of spending time with the person they care for, (b) the absence of faith as a caregiving driver, and (c) the challenge of watching the declining health of a parent. We highlight how the different motivations to care are intertwined and dynamic. This is illustrated by the linking of obligation and reciprocity in our dataset and positive and negative experiences of caregiving.Alzheimer's Society. Grant Numbers: 348, AS-PR2-16-001.

Living well with dementia: An exploratory matched analysis of minority ethnic and white people with dementia and carers participating in the IDEAL programme
YesThe increasing heterogeneity of the population of older people is reflected in an increasing number of people with dementia and carers drawn from minority ethnic groups. Data from the IDEAL study are used to compare indices of 'living well' among people with dementia and carers from ethnic minority groups with matched white peers.
We used an exploratory cross-sectional case-control design to compare 'living well' for people with dementia and carers from minority ethnic and white groups. Measures for both groups were quality of life, life satisfaction, wellbeing, loneliness, and social isolation and, for carers, stress, relationship quality, role captivity and caring competence.
The sample of people with dementia consisted of 20 minority ethnic and 60 white participants and for carers 15 and 45 respectively. People with dementia from minority ethnic groups had poorer quality of life (-4.74, 95% CI: -7.98 to -1.50) and higher loneliness (1.72, 95% CI: 0.78-2.66) whilst minority ethnic carers had higher stress (8.17, 95% CI: 1.72-14.63) and role captivity (2.00, 95% CI: 0.43-3.57) and lower relationship quality (-9.86, 95% CI: -14.24 to -5.48) than their white peers.
Our exploratory study suggests that people with dementia from minority ethnic groups experience lower quality of life and carers experience higher stress and role captivity and lower relationship quality than their white peers. Confirmatory research with larger samples is required to facilitate analysis of the experiences of specific minority ethnic groups and examine the factors contributing to these disadvantages.Economic and Social Research Council.

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating'
The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use. In particular, it cannot be used with confidence for 'blind dating'. The compilation of isotopic data on carbonate rocks reveals a high level of inconsistency between various carbon isotope age curves constructed for Neoproteozoic seawater, caused by a relatively high frequency of both global and local delta C-13(carb) fluctuations combined with few reliable age determinations. Further complication is caused by the unresolved problem as to whether two or four glaciations, and associated negative delta C-13(carb) excursions, can be reliably documented. Carbon isotope stratigraphy cannot be used alone for geological correlation and 'blind dating'. Strontium isotope stratigraphy is a more reliable and precise tool for stratigraphic correlations and indirect age determinations. Combining strontium and carbon isotope stratigraphy, several discrete ages within the 590-544 Myr interval, and two age-groups at 660-610 and 740-690 Myr can be resolved
Influence of Anodic Conditions on Self-ordered Growth of Highly Aligned Titanium Oxide Nanopores
Self-aligned nanoporous TiO2templates synthesized via dc current electrochemical anodization have been carefully analyzed. The influence of environmental temperature during the anodization, ranging from 2 °C to ambient, on the structure and morphology of the nanoporous oxide formation has been investigated, as well as that of the HF electrolyte chemical composition, its concentration and their mixtures with other acids employed for the anodization. Arrays of self-assembled titania nanopores with inner pores diameter ranging between 50 and 100 nm, wall thickness around 20–60 nm and 300 nm in length, are grown in amorphous phase, vertical to the Ti substrate, parallel aligned to each other and uniformly disordering distributed over all the sample surface. Additional remarks about the photoluminiscence properties of the titania nanoporous templates and the magnetic behavior of the Ni filled nanoporous semiconductor Ti oxide template are also included
