The Need for National Training Standards and Guidelines for Privately Paid Geriatric Home Caregivers

Contrary to public opinion, America's institution-centered long-term care (LTC) system does not serve the majority of older adults. Currently, nursing homes serve less than 20% of older adults needing care, and thus do not provide a viable solution for future caregiving needs. While these LTC institutions will continue to play an important role in providing care for our most frail older adults who need skilled nursing and/or medical care, they will not be necessary for the vast majority of older adults who simply need nonmedical caregiving, that is, help with activities of daily living. There is, and will continue to be, an urgent need for a large cadre of trained caregivers for older adults who live at home. This issue brief calls for the development of national training standards and a caregiver certifying organization that provides national oversight

Ambient temperature recorder

A temperature data recorder, designated the Ambient Temperature Recorder (ATR-4), was developed at NASA Ames Research Center to meet particular requirements for space life sciences experiments. The small, self-contained, four-channel, battery-powered device records 32 kilobytes of temperature data over a range of -40 to +60 C at four sampling intervals ranging from 1.875 to 15 minutes. Data is stored in its internal electronic memory for later readout by a personal computer

Film cooling heat transfer on a turbine airfoil

The objectives of the current program are to develop an analytical approach, based on boundary layer theory, for predicting the effects of airfoil cooling on downstream heat transfer rates and to verify the resulting analytical method by comparison of predictions with hot cascade data obtained under this program

Too-big-to-fail after FDICIA

This reprint of a 1993 article outlines what Congress intended the Federal Deposit Insurance Corporation Improvement Act of 1991 to accomplish. A new preface discusses FDICIA's successes and failures as well as research calling for clearer policies to deal with the problem of "too big to fail" banks.Federal Deposit Insurance Corporation Improvement Act of 1991 ; Deposit insurance

Theoretical prediction of the impact of Auger recombination on charge collection from an ion track

A recombination mechanism that significantly reduces charge collection from very dense ion tracks in silicon devices was postulated by Zoutendyk et al. The theoretical analysis presented here concludes that Auger recombination is such a mechanism and is of marginal importance for higher density tracks produced by 270-MeV krypton, but of major importance for higher density tracks. The analysis shows that recombination loss is profoundly affected by track diffusion. As the track diffuses, the density and recombination rate decrease so fast that the linear density (number of electron-hole pairs per unit length) approaches a non-zero limiting value as t yields infinity. Furthermore, the linear density is very nearly equal to this limiting value in a few picoseconds or less. When Auger recombination accompanies charge transport processes that have much longer time scales, it can be simulated by assigning a reduced linear energy transfer to the ion

Recent advances in structural dynamics of large space structures

Recent progress in the area of structural dynamics of large space structures is reviewed. Topics include system identification, large angle slewing of flexible structures, definition of scaling limitations in structural models, and recent results on a tension-stabilized antenna concept known as the hoop-column. Increasingly complex laboratory experiments guide most of the activities leading to realistic technological developments. Theoretical progress in system identification based on system realization theory resulting in unification of several methods is reviewed. Experimental results from implementation of a theoretical large-angle slewing control approach are shown. Status and results of the development of a research computer program for analysis of the transient dynamics of large angle motion of flexible structures are presented. Correlation of results from analysis and vibration tests of the hoop-column antenna concepts are summarized

Turbine airfoil film cooling

Emphasis is placed on developing more accurate analytical models for predicting turbine airfoil external heat transfer rates. Performance goals of new engines require highly refined, accurate design tools to meet durability requirements. In order to obtain improvements in analytical capabilities, programs are required which focus on enhancing analytical techniques through verification of new models by comparison with relevant experimental data. The objectives of the current program are to develop an analytical approach, based on boundary layer theory, for predicting the effects of airfoil film cooling on downstream heat transfer rates and to verify the resulting analytical method by comparison of predictions with hot cascade data obtained under this program

Normal approximation for coverage models over binomial point processes

We give error bounds which demonstrate optimal rates of convergence in the CLT for the total covered volume and the number of isolated shapes, for germ-grain models with fixed grain radius over a binomial point process of $n$ points in a toroidal spatial region of volume $n$. The proof is based on Stein's method via size-biased couplings.Comment: Published in at http://dx.doi.org/10.1214/09-AAP634 the Annals of Applied Probability (http://www.imstat.org/aap/) by the Institute of Mathematical Statistics (http://www.imstat.org
