While there has been widespread recent interest in men's health issues, and prostate cancer in particular, there have been few studies to determine which issues are important from the viewpoint of men themselves. This study was undertaken to identify genitourinary issues of concern to older men. A series of 19 focus groups involved 137 men and 14 women from a broad demographic background. Men expressed consistent concern about urinary symptoms, prostate cancer and sexual function. They revealed misunderstanding and a desire for more information about all issues. Urinary symptoms had a high impact on quality of life that could be made worse by environmental constraints such as working conditions and availability of toilets. Prostate cancer was a concern in all groups, even those at low risk, and men believed that screening for prostate cancer should be offered. Men believed sexuality was not recognised as an issue of concern to older people. Potential barriers to health action included stoicism, not talking about health issues and poor relationships with doctors. The study suggests a substantial need for community and professional education and for health promotion focused on preventable morbidity.
Evolutionary relatedness underlies patterns of functional diversity in the natural world. Hyperspectral remote sensing has the potential to detect these patterns in plants through inherited patterns of leaf reflectance spectra. We collected leaf reflectance data across the California flora from plants grown in a common garden. Regions of the reflectance spectra vary in the depth and strength of phylogenetic signal. We also show that these differences are much greater than variation due to the geographic origin of the plant. At the phylogenetic extent of the California flora, spectral variation explained by the combination of ecotypic variation (divergent evolution) and convergent evolution of disparate lineages was minimal (3%–7%) but statistically significant. Interestingly, at the extent of a single genus (Arctostaphylos) no unique variation could be attributed to geographic origin. However, up to 18% of the spectral variation among Arctostaphylos individuals was shared between phylogeny and intraspecific variation stemming from ecotypic differences (i.e., geographic origin). Future studies could conduct more structured experiments (e.g., transplants or observations along environmental gradients) to disentangle these sources of variation and include other intraspecific variation (e.g., plasticity). We constrain broad‐scale spectral variability due to ecotypic sources, providing further support for the idea that phylogenetic clusters of species might be detectable through remote sensing. Phylogenetic clusters could represent a valuable dimension of biodiversity monitoring and detection.
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.
