OBJECTIVES To model the incremental cost-utility of seven interventions reported as effective for preventing falls in older adults. DESIGN Mathematical epidemiological model populated by data based on direct clinical experience and a critical review of the literature. SETTING Model represents population level interventions. PARTICIPANTS No human(More)
Many animals orient to odor sources in aquatic habitats where different flows and substrates affect the hydrodynamics of benthic boundary layers. Since the dispersal of chemicals is due to the fluid mechanics of a particular environment, we quantified the changes in the fine structure of an odor plume under different hydrodynamic conditions in the benthic(More)
We report the psychological status of ten people with the Dubowitz syndrome, an autosomal recessive condition characterized by intrauterine and postnatal growth retardation, microcephaly, and high-pitched hoarse voice. Results indicate that the level of intellectual functioning among children with Dubowitz syndrome varies from severe retardation to average(More)
CONTEXT Age-related memory decline affects a large proportion of older adults. Cognitive training, physical exercise, and other lifestyle habits may help to minimize self-perception of memory loss and a decline in objective memory performance. OBJECTIVE The purpose of this study was to determine whether a 6-week educational program on memory training,(More)
Reliable changes in a variety of behaviors, or classes of behaviors, when only one is manipulated experimentally, have demonstrated that even topographically dissimilar responses can be functionally related. We investigated such a relationship between topographically different child behaviors (compliance and inappropriate activities) by using a methodology(More)
The Jurassic and Cretaceous are considered to have been warmer than today on the basis of various climate data and model studies. Here, we use the available global record of climate-sensitive sediments, plants, and dinosaurs to infer broadscale geographic patterns for the Late Jurassic. These provide a context for our more detailed accounts of the Morrison(More)
Osteoporosis affects approximately 26% of women and 4% of men after the age of 65 years. However, the diffusion of knowledge about osteoporosis risk factors, prevention and treatment remains low. The purpose of this longitudinal study was to investigate the value of adding initial and refresher osteoporosis education classes to a bone health screening(More)
Nonacceptance of prescribed oral medications among young children hinders medical treatment. The literature pertaining to teaching children how to swallow pills or capsules is reviewed. In addition, a multiple case study demonstrating the efficacy of a brief, easy-to-implement procedure designed to promote capsule acceptance is presented. In this study, two(More)
