Does taking vitamin, mineral and fatty acid supplements prevent cognitive decline? A systematic review of randomized controlled trials

Background Observational studies have shown associations between nutritional status and cognition in later life but evidence from intervention studies is unclear. The present study systematically reviewed the evidence on the effect of nutrient supplementation on cognitive function in people aged ≥65 years. Methods Databases including MEDLINE and EMBASE were searched up to 1 September 2006. Randomized controlled trials using at least one kind of vitamin, mineral or omega-3 fatty acid, evaluating standardized neuropsychological test(s), were included. There were no restrictions on participants' baseline nutritional status or cognitive function. Quality assessment and data abstraction were conducted by one author and checked by another. Results Of 4229 articles retrieved, 22 trials (3442 participants) were identified. Many were small, short duration and of poor methodology. Only 16 out of 122 cognitive tests were significantly different between groups. A meta-analysis showed no significant effect of taking B vitamins or antioxidant vitamins on global cognitive function. There was insufficient evidence to evaluate the effect of omega-3 fatty acids on any cognitive domains. Conclusion There was little evidence of a beneficial effect from taking B vitamins or antioxidant supplements on global cognitive function in later life. Larger-scale randomized controlled trials of longer duration in selected age groups are needed.Institute of Applied Health Science, University of Aberdeen; Chief Scientist Office of the Scottish Government Health Directorates; Chief Scientist of the Scottish Government Health Directorate

Probation, credibility and justice

This paper explores the difficulties that arise for probation agencies or those that deliver community sanctions in developing and maintaining their credibility in prevailing ‘late-modern’ social conditions. It begins by questioning the limits of the pursuit and promise of ‘public protection’ as a source of credibility, and then proceeds to examine the emergence of an alternative strategy – based principally on reparation and ‘payback’ – in Scotland, arguing that these Scottish developments have much to say to the emerging debates in England and Wales (and elsewhere) about the ‘rehabilitation revolution’ and the proper use of imprisonment. The paper provides a critical account of the development and meaning of the Scottish version of ‘payback’, linking it to some important philosophical and empirical studies that may help to steer the development of payback away from a ‘merely punitive’ drift. In the conclusion, I argue that probation agencies and services need to engage much more deeply and urgently with their roles as justice services, rather than as ‘mere’ crime reduction agencies

International Evidence Review of Conditional (Suspended) Sentences: Final Report

This report reviews international use of conditional sentences, specifically understood to mean a criminal sentence of imprisonment which is suspended pending a person's satisfaction of specific criteria. These sentences are being considered in jurisdictions seeking ways of managing prison population growth. The laws and any information about use of such sentences among selected countries is considered in the first part. The second part reviews research on perceptions of such sentences, and community-based sentences generally. This research was requested by and submitted to the Scottish Government

Paths to resettlement: understanding the interplay of work and other factors in journeys out of homelessness

Paid employment has been viewed by successive governments in the UK as critical in making transitions out of homelessness, even when combined with problems like substance misuse, criminality or mental ill health. This article presents evidence from a study that sought to subject this belief to critical examination by exploring the relationship between promoting employability and other aspects of resettlement in the lives of a sample of thirty people experiencing homelessness and complex needs. Participants were interviewed twice at six to nine-month intervals to explore their changing motivations and perceptions of housing, work, relationships and hopes for the future. Analysis used 'pathways' imagery to locate participants along an integrated pathway to understand how these factors related to one another in the pursuit of resettlement. We conclude that all respondents valued work, but its pursuit depended on the structural obstacles that participants faced. People’s location along a resettlement pathway was determined by their sense of control over circumstances, their success in overcoming barriers and the presence of significant others in their lives, and the pursuit of employment among homeless people needs to take account of progress in their resettlement journeys and the place of work in their aspirations

Children’s Food and Drink Purchasing Behaviour ‘‘Beyond the School Gate’’ : The Development of a Survey Module

Copyright © 2013 Wendy J.Wills et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly citedMany children eat a diet which supplies a higher than recommended amount of nonmilk extrinsic sugars and saturated fatty acids. The school setting is often targeted for nutrition intervention as many children consume food at school. In Scotland, attempts have been made to improve the nutritional content of food in schools and attention has now turned to food and drink available “beyond the school gate.” This paper describes the development of a module on food and drink purchasing behaviour. The Food Purchasing Module was designed to collect data, for the first time, from a representative sample of children aged 8–16 years about food and drinks purchased on the way to/from school, during break time/free periods, and at lunchtime, from outlets around schools. Cognitive testing of the module highlighted that younger children find self-completion questionnaires problematic. Older children have fewer problems with self-completion questionnaires butmany do not follow question routing, which has implications for the delivery of future surveys. Development of this survey module adds much needed evidence about effectively involving children in surveys. Further research exploring food and drinks purchased beyond the school gate is needed to continue to improve the nutritional quality of children’s dietsPeer reviewe

Reexamining evidence-based practice in community corrections: beyond 'a confined view' of what works

This article aims to reexamine the development and scope of evidence-based practice (EBP) in community corrections by exploring three sets of issues. Firstly, we examine the relationships between the contested purposes of community supervision and their relationships to questions of evidence. Secondly, we explore the range of forms of evidence that might inform the pursuit of one purpose of supervision—the rehabilitation of offenders—making the case for a fuller engagement with “desistance” research in supporting this process. Thirdly, we examine who can and should be involved in conversations about EBP, arguing that both ex/offenders’ and practitioners’ voices need to be respected and heard in this debate

Drying Considerations for the 1996 Corn Crop

The com harvest season has already started on some farms and is rapidly approaching for many others. Current market opportunities and previous contractual arrangements have some farmers thinking about starting their harvest earlier than usual. Other factors also suggest that a substantial portion of this year\u27s crop could be harvested at moisture contents between 24 and 32%
