A Review of Geriatric Communication

Communication errors are rampant in our society and no population is exempt from this problem. This article takes a closer look at communication accommodation theories, specifically under and overaccommodation. These are two predominant communication errors that healthcare workers and geriatric patients both experience while working together

Can Children’s Museums Deliver Effective Health Outreach?: Evaluation Results of the HealthWorks! Be A Food Groupie Program for Elementary Students

Objectives: We evaluated the Be A Food Groupie (BAFG) program’s impact on health/nutrition knowledge among elementary students who received BAFG at HealthWorks! children’s museum. Methods: In 2012-2013, we conducted a matched comparison evaluation using pre-/post-tests among 446 intervention and 524 comparison students (N = 970) in Grades 3-5 recruited from 11 Mississippi schools to determine whether BAFG improved health/nutrition knowledge across three domains: 1) comprehending food labels, 2) understanding serving sizes, 3) understanding food groups. Results: After controlling for pre-test scores, ANCOVA results indicate that intervention students scored significantly higher on the post-test across all three domains and across all three grades as compared to comparison students. Third-grade intervention students had significantly higher post-test scores overall than their comparison counterparts, F (1,288) = 52.02, p \u3c .001, h2 = .153. Fourth-grade intervention students had significantly higher post-test scores overall than their comparison counterparts, F (1,373) = 58.52, p \u3c .001, h2 = .136. Fifth-grade intervention students had significantly higher post-test scores overall than their comparison counterparts, F (1,300) = 151.71, p \u3c .001, h2 = .336. Conclusion: BAFG results support the argument that interactive health/nutrition education programs at children’s museums can positively impact children’s health knowledge and, therefore, can support learning beyond the school setting. When children’s museums and schools collaborate to develop long-term partnerships to enhance children’s learning experiences that—like BAFG—meet state-mandated requirements, programmatic impacts can be further augmented. Children’s museums can provide supplemental health-related education—including obesity prevention information—that can be reinforced at school, home, and in the community

Technique for predicting temperature distribution in gases

Simple algebraic equations enable calculation of the temperature distribution throughout a heat generating, radiation gas. They apply over the entire range of opacities, for any heat flux, for a temperature dependent absorption coefficient, and for a non-uniform distribution of volumetric heat sources

Schwinger effect for non-Abelian gauge bosons

We investigate the Schwinger effect for the gauge bosons in an unbroken non-Abelian gauge theory (e.g. the gluons of QCD). We consider both constant "color electric" fields and "color magnetic" fields as backgrounds. As in the Abelian Schwinger effect we find there is production of "gluons" for the color electric field, but no particle production for the color magnetic field case. Since the non-Abelian gauge bosons are massless there is no exponential suppression of particle production due to the mass of the electron/positron that one finds in the Abelian Schwinger effect. Despite the lack of an exponential suppression of the gluon production rate due to the masslessness of the gluons, we find that the critical field strength is even larger in the non-Abelian case as compared to the Abelian case. This is the result of the confinement phenomenon on QCD.Comment: 15 pages revtex, contribution to IF-YITP GR+HEP+Cosmo International Symposium VI Naresuan University, Thailan

An improved lateral control wheel steering law for the Transport Systems Research Vehicle (TSRV)

A lateral control wheel steering law with improved performance was developed for the Transport Systems Research Vehicle (TSRV) simulation and used in the Microwave Landing System research project. The control law converted rotational hand controller inputs into roll rate commands, manipulated ailerons, spoilers, and the rudder to achieve the desired roll rates. The system included automatic turn coordination, track angle hold, and autopilot/autoland modes. The resulting control law produced faster roll rates (15 degrees/sec), quicker response to command reversals, and safer bank angle limits, while using a more concise program code

Market definition study of photovoltaic power for remote villages in developing countries

The potential market of photovoltaic systems in remote village applications in developing countries is assessed. It is indicated that photovoltaic technology is cost-competitive with diesel generators in many remote village applications. The major barriers to development of this market are the limited financial resources on the part of developing countries, and lack of awareness of photovoltaics as a viable option in rural electrification. A comprehensive information, education and demonstration program should be established as soon as possible to convince the potential customer countries and the various financial institutions of the viability of photovoltaics as an electricity option for developing countries

Market definition study of photovoltaic power for remote villages in the United States

A grass roots evaluation of the market potential was carried out for photovoltaic applications in remote villages in the U. S. and its possessions. An estimate of almost 14 MWp available for conversion from a potential to a real market was defined. The total power potential was based on the energy needs of almost 400 sites reported by Federal agencies and inputs from over 100 Indian tribes. The methodology used, the results achieved, and some recommendations of how to convert this domestic market potential into a real market are detailed

Use of Aluminum-Foil and Oat-Straw Mulches for Controlling Aster Leafhopper, \u3ci\u3eMacrosteles Fascifrons\u3c/i\u3e (Homoptera: Cicadellidae), and Aster Yellows in Carrots.

Aluminum-foil and oat-straw mulches significantly (P \u3c 0.05) reduced aster leafhopper numbers on carrots compared to an untreated control and a malathion spray treatment during the first half of the growing season. The amount of reflected light was significantly higher in both aluminum-foil and oat-straw mulched plots compared to unmulched treatments. Mulch effectiveness decreased when the closing carrot canopy reduced surface area of reflective mulches and amount of reflected light The percentage of aster yellows-infected plants was significantly lower (P \u3c 0.05) in aluminum-foil and straw mulches and in the malathion spray plots compared to the untreated control. Results demonstrated that aluminum-foil and straw mulches gave control of aster leafhoppers and aster yellows in carrots equal to that of a conventional insecticide spray program

The NASA Langley building solar project and the supporting Lewis solar technology program

The use of solar energy to heat and cool a new office building that is now under construction is reported. Planned for completion in December 1975, the 53,000 square foot, single story building will utilize 15,000 square feet of various types of solar collectors in a test bed to provide nearly all of the heating demand and over half of the air conditioning demand. Drawing on its space-program-developed skills and resources in heat transfer, materials, and systems studies, NASA-Lewis will provide technology support for the Langley building project. A solar energy technology program underway at Lewis includes solar collector testing in an indoor solar simulator facility and in an outdoor test facility, property measurements of solar panel coatings, and operation of a laboratory-scale solar model system test facility. Based on results obtained in this program, NASA-Lewis will select and procure the solar collectors for the Langley test bed
