Current public health and aging service agency personnel have little training in gerontology, and virtually no training in evidence-based health promotion and disease management programs for older adults. These programs are rapidly becoming the future of our community-based long-term care support system. The purpose of this project was to develop and test a model community college career technical education program, Skills for Healthy Aging Resources and Programs (SHARP), for undergraduate college students, current personnel in aging service and community organizations, and others interested in retraining. A multidisciplinary cross-sector team from disciplines of public health, sociology, gerontology and nursing developed four competency-based courses that focus on healthy aging, behavior change strategies, program management, an internship, and an option for leader training in the Chronic Disease Self-Management Program. To enhance implementation and fidelity, intensive faculty development training was provided to all instructors and community agency partners. Baseline and postprogram evaluation of competencies for faculty and students was conducted. Process evaluation for both groups focused on satisfaction with the curricula and suggestions for program improvement. SHARP has been piloted five times at two community colleges. Trainees (n = 113) were primarily community college students (n = 108) and current aging service personnel (n = 5). Statistically significant improvements in all competencies were found for both faculty and students. Process evaluation outcomes identified the needed logical and component adaptations to enhance the feasibility of program implementation, dissemination, and student satisfaction. The SHARP program provides a well-tested, evidence-based effective model for addressing workforce preparation in support of healthy aging service program expansion and delivery. © 2014 Society for Public Health Education.

The mineralogical, compositional and stable isotopic variability of lacustrine carbonates are frequently used as proxies for ancient paleoenvironmental change in continental settings, under the assumption that precipitated carbonates reflect conditions and chemistry of ancient lake waters. In some saline and alkaline lake systems, however, authigenic clay minerals, forming at or near the sediment water interface, are a major sedimentary component. Often these clays are rich in Mg, influencing the geochemical budget of lake waters, and are therefore expected to influence the properties of contemporaneous authigenic carbonate precipitates (which may also contain Mg). This paper documents evidence for a systematic feedback between clay mineral and carbonate authigenesis through multiple precessionally driven, m-scale sedimentary cycles in lacustrine oil-shale deposits of the Eocene Green River Formation from the Uinta Basin (NE Utah). In the studied section, authigenic, Mg-rich, trioctahedral smectite content varies cyclically between 9 and 39wt.%. The highest concentrations occur in oil-shales and calcareous mudstones deposited during high lake level intervals that favored sedimentary condensation, lengthening the time available for clay diagenesis and reducing dilution by other siliciclastic phases. An inverse relation between dolomite percentage of carbonate and trioctahedral smectite abundance suggests the Mg uptake during clay authigenesis provides a first order control on carbonate mineralogy that better explains carbonate mineralogical trends than the possible alternative controls of (1) variable Mg/Ca ratios in lake water and (2) degree of microbial activity in sediments. We also observe that cyclical change in carbonate mineralogy, believed to be induced by clay authigenesis, also causes isotopic covariation between δ 13C PDB and δ 18O PDB of bulk sediments because of differences in the equilibrium fractionation factors of dolomite and calcite (∼2‰ and ∼2.6%, respectively). This provides an alternative mechanism for the common pattern of isotopic covariation, which is typically attributed to the effect of simultaneous changes in water balance and biological activity on the carbon and oxygen isotopic composition of lake waters. These findings may help improve paleoenvironmental reconstructions based on lacustrine carbonate records by adding to the factors known to influence the mineralogical, compositional and stable isotopic signals recorded by lacustrine carbonates. © 2012 Elsevier Ltd.

We have developed a robotic system that interacts with the user, and through repeated interactions, adapts to the user so that the system becomes semi-autonomous and acts proactively. In this work we show how to design a system to meet a user's preferences, show how robot pro-activity can be learned and provide an integrated system using verbal instructions. All these behaviors are implemented in a real platform that achieves all these behaviors and is evaluated in terms of user acceptability and efficiency of interaction. Copyright 2011 ACM. Source
