Evaluation of the Wellspring Model for Improving Nursing Home Quality

Examines how successfully the Wellspring model improved the quality of care for residents of eleven nonprofit nursing homes in Wisconsin. Looks at staff turnover, and evaluates the impact on facilities, employees, residents, and cost

The Slitmask Alignment Tool: robust, efficient, and astronomer-friendly software for aligning multi-object slitmasks

Multi-object spectroscopy via custom slitmasks is a key capability on three instruments at the W. M. Keck Observatory. Before observers can acquire spectra they must complete a complex procedure to align each slit with its corresponding science target. We developed the Slitmask Alignment Tool (SAT), to replace a complex, inefficient, and error-prone slitmask alignment process that often resulted in lost sky time for novice and experienced observers alike. The SAT accomplishes rapid initial mask alignment, prevents field misidentification, accurately predicts alignment box image locations, corrects for flexure-induced image displacement, verifies the instrument and exposure configuration, and accommodates both rectangular and trapezoidal alignment box shapes. The SAT is designed to lead observers through the alignment process and coordinate image acquisition with instrument and telescope moves to improve efficiencies. By simplifying the process to just a few mouse clicks, the SAT enables even novice observers to achieve robust, efficient, and accurate alignment of slitmasks on all three Keck instruments supporting multislit spectroscopy, saving substantial observing time

Imaging the phase of an evolving Bose-Einstein condensate wavefunction

We demonstrate a spatially resolved autocorrelation measurement with a Bose-Einstein condensate (BEC) and measure the evolution of the spatial profile of its quantum mechanical phase. Upon release of the BEC from the magnetic trap, its phase develops a form that we measure to be quadratic in the spatial coordinate. Our experiments also reveal the effects of the repulsive interaction between two overlapping BEC wavepackets and we measure the small momentum they impart to each other

Gravitational wave detectors based on matter wave interferometers (MIGO) are no better than laser interferometers (LIGO)

We show that a recent claim that matter wave interferometers have a much higher sensitivity than laser interferometers for a comparable physical setup is unfounded. We point out where the mistake in the earlier analysis is made. We also disprove the claim that only a description based on the geodesic deviation equation can produce the correct physical result. The equations for the quantum dynamics of non-relativistic massive particles in a linearly perturbed spacetime derived here are useful for treating a wider class of related physical problems. A general discussion on the use of atom interferometers for the detection of gravitational waves is also provided.Comment: 16 pages, REVTeX4; minor changes, one figure and a few references were added, an additional appendix was included where we explain why, contrary to the claims in gr-qc/0409099, the effects due to the reflection off the mirrors cancel out in the final result for the phase shif

Rehabilitation in Nursing Homes: A Cross-National Comparison of Recipients

Objective: To examine the prevalence of therapy use in nursing homes in selected countries and to describe the characteristics of nursing home residents who receive therapy. Design and sampling: The design of the study is cross-sectional, using Minimum Data Set (MDS) assessments of nursing home residents. The sample includes all nursing home residents in six US states (n=273491), in Copenhagen, Denmark (n=;3451), Reyjkavik, Iceland (n=1254), and selected locations in Italy (n=1089) and Japan (n=1255). Method: We determined who had received physical or occupational therapy treatments in the last 7 days. Demographic and clinical characteristics of recipients were compared relative to other nursing home residents within each country. Results: In the five countries, the prevalence of receiving therapy was 31% (Iceland), 30% Qapan), 23% (Denmark), 14% (Italy) and 11% (USA). Substantial proportions of the recipients were over the age of 85, were clinically stable and had been in the nursing home for longer than 90 days. Across all countries, residents with poorer activities of daily living (ADL) scores but good cognitive scores were more likely to receive therapy than other residents. Rehabilitation nursing, an adjunct to therapy, was concentrated on residents with poor ADL scores. Conclusions: Substantial numbers of long-stay residents receive therapy in nursing homes, including those over the age of 85 years and those with cognitive impairment. Hence, future rehabilitation outcome studies can involve these previously understudied patient population

Conceptual frameworks linking agriculture and food security

Many conceptual frameworks have been developed to facilitate understanding and analysis of the linkages between agriculture and food security. Despite having usefully guided analysis and investment, these frameworks exhibit wide diversity in perspectives, assumptions and application. This Review Article examines this diversity, providing an approach to assess frameworks and suggesting improvements in the way they are specified and applied. Using criteria-based systems modelling conventions, we evaluate 36 frameworks. We find that many frameworks are developed for the purpose of illustration rather than analysis and do not clearly indicate causal relationships, tending to ignore the dynamic (stability) dimensions of agriculture and food security and lacking clear intervention points for improving food security through agriculture. By applying system modelling conventions to a widely used framework, we illustrate how such conventions can enhance the usefulness of a framework for overall illustration purposes, delineate hypotheses on agriculture–food security links and examine potential impacts of interventions.acceptedVersio
