This study explored whether physical activity and sleep, combined with the biomarker C-reactive protein, indexed positive health in older men. Many were former prisoners of war, with most remaining psychologically resilient and free of any psychiatric diagnoses. Activity and sleep were recorded through actigraphy in 120 veterans (86 resilient and 34 nonresilient) for 7 days. Resilient men had higher physical activity, significantly lower C-reactive protein levels, and 53 percent had lower cardiac-disease risk compared to nonresilient men. Sleep was adequate and not associated with C-reactive protein. Results suggest continued study is needed in actigraphy and C-reactive protein as means to index positive health.
PurposeThis paper aims to analyse the differing views on and needs of librarians and their managers for continuing professional development (CPD).Design/methodology/approachThis article draws on the findings of a survey conducted by the authors in 2005. The survey was an assessment of the CPD needs of New Zealand's librarians and library assistants.FindingsThere is a significant gap between the CPD that individuals want, and that which their managers think they should have. Organisations overall need a greater strategic focus on CPD to ensure that budgets are spent well, staff are appropriately skilled, and the impact of CPD on both individuals and the organisation is tangible. Individuals need to take more responsibility for ensuring their needs are met.Originality/valueHighlights a dual focus on CPD across the profession, in the light of the decision by the Library and Information Association of New Zealand Aotearoa to adopt professional registration.
Diminished vitamin D is common among older individuals. Sunlight contributes more to vitamin D synthesis than diet or supplementation. This study examined associations between objectively measured light exposure, vitamin D serum levels, and bone biomarkers in 100 men aged over 60 years. Light exposure was measured in lux via Actigraph monitors for 1 week. Significantly, greater levels of vitamin D were observed in participants with higher light exposure. Seasonal differences in lux were also noted. Significant differences in bone markers were not found. Objective measurement of light exposure is an inexpensive, simple, and effective way to address vitamin D deficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
