Evidence-Based Nursing Education on Dementia and Dementia Care

The purpose of this research study was to identify the relationship between nursing education and nurses’ knowledge of dementia and dementia care in a long-term care setting. Residents of long-term care settings who have dementia often have behavior problems that affect their quality of life, psychosocial dynamics, and the requirements of their nursing care. The effectiveness of the nursing care delivered to nursing home residents with dementia and behavior problems makes a crucial difference in their quality of life. Best practice nursing to promote optimal dementia care uses nonpharmacological interventions and avoids unnecessary psychotropic medication in residents with age-related dementia and behavior problems. This research study showed that effective nursing education improved nursing staff’s Dementia Knowledge Assessment Tool Version Two scores, indicating increases in nursing knowledge of dementia and dementia care. That is, with education, students had an increased understanding of dementia care, communication, and teamwork ethics

Turkey Production in South Dakota

The turkey is truly an American bird and suggests not only Thanksgiving to Americans but America itself to the world. The Cyclopedia of Agriculture comments that America has furnished but few domestic animals and mentions the llama of South America, the turkey, and the bison as a third possible example

Tradeoff between short-term and long-term adaptation in a changing environment

We investigate the competition dynamics of two microbial or viral strains that live in an environment that switches periodically between two states. One of the strains is adapted to the long-term environment, but pays a short-term cost, while the other is adapted to the short-term environment and pays a cost in the long term. We explore the tradeoff between these alternative strategies in extensive numerical simulations, and present a simple analytic model that can predict the outcome of these competitions as a function of the mutation rate and the time scale of the environmental changes. Our model is relevant for arboviruses, which alternate between different host species on a regular basis.Comment: 9 pages, 3 figures, PRE in pres

A clinical comparison of three astigmatic tests

Astigmatism is a refractive condition in which the optical system of the eye cannot form a point image of a point object. This is a consequence of varying curvatures of the cornea and or the lens of the eye and is present in a large majority of the detection of astigmatism. This study takes a look at three subjective tests for astigmatism. Two of these, the Jackson cross cylinder and the Pratt near cylinder, are well established tests used at Pacific University clinics. The third test was designed by Dr. William Preston. Dr. Preston’s technique utilizes a near point card with a sunburst target which presents a series of radially arranged lines every 15 degrees. The card also presents three lines of Snellen acuity letter, 20/40, 20/30, and 20/20, which are used in fogging and cylinder axis refinement. This study concluded that there was no statistical difference between the magnitude and direction of the astigmatic refractive error found by the Preston technique and the Jackson cross cylinder. In addition, the study found that there was a statistically significant difference between the magnitude and the direction of the astigmatic refractive error found by the Preston technique and the Pratt near cylinder. Although these results were statistically significant, the clinical difference between the tests was minimal

Defoliation responses of different grapevine cultivars to postharvest ethephon treatments

The defoliation responses of several grapevine cultivars to postharvest ethephon sprays at 0, 500, 2000, 5000 ppm were observed. Sprays were applied at the beginning of October to vines of Barbera, Carignane, Emerald Seedless, Ribier, Ruby Seedless, Thompson Seedless and Flame Tokay cultivars.The most effective concentration was 5000 ppm. The defoliation response varied greatly among the varieties. Barbera and Carignane were almost completely defoliated 20-30 d after treatment, whereas Flame Tokay showed no response. However, high concentrations of ethephon resulted in a considerable delay in shoot development the following spring.Défoliation induite en différents cépages par un traitement avec de l'éthéphon après la vendangeLa défoliation causée par des traitements d'éthephon (0, 500, 2000, 5000 ppm) a été étudiée sur différents cépages (V. vinifera).Les applications ont été faites le 10 octobre sur les cépages à raisin de table et de cuve ci-après: Barbera, Carignane; Emerald Seedless, Ribier, Ruby Seedless, Thompson Seedless et Flame Tokay. La concentration de 5000 ppm se révéla la plus efficace. La défoliation des plantes traitées a été très différente selon les cépages: Barbera et Carignane par exemple ont été presque complètement privés des feuilles après 20-30 d du traitement, tandis que le Flame Tokay ne donna qu'une très faible réponse.Il faut signaler en tout cas que les concentrations les plus fortes d'éthéphon ont causé un retard considerable dans le débourrement du printemps suivant

Effect of application of naphthaleneacetic acid on berry thinning of Carignane grapes

Application of NAA on Carignane grapes at 70 % calyptra fall reduced berryset and weight per cluster. Crop yield per vine was decreased both by application of NAA at bloom at 10 and 25 ppm and at 2 weeks after bloom at 25 ppm. °Brix was usually increased by NAA applied at bloom or 2 weeks after bloom. However, total titratable acidity did not change as a result of NAA in any of the treatments. The looseness of clusters treated at the bloom stage tended to increase with higher levels of NAA. NAA has not been cleared for use on grapes as a thinning agent in the United States by the Environmental Protection Agency.Einfluß der Naphthylessigsäure-Behandlung auf das Ausdünnen der Trauben bei der Rebsorte CarignaneWurden die Infloreszenzen der Sorte Carignane mit NES behandelt, wenn 70 % der Calyptren abgefallen waren, so waren sowohl der Beerenansatz als auch das Gewicht je Traube herabgesetzt. Der Traubenertrag je Rebe war bei Anwendung von 10 und 25 ppm NES zur Blütezeit und ebenso bei Behandlung mit 25 ppm NES 2 Wochen nach der Blüte verringert. Die gesamte titrierbare Säure war jedoch bei keiner Variante verändert. Die durch NES-Anwendung in der Blühphase erzielte Lockerbeerigkeit der Trauben verstärkte sich durch höhere Konzentrationen. Das Umweltschutzamt der USA hat über die Zulassung von NES als Ausdünnungsmittel noch nicht entschieden

Reply to Comment on "Cosmic rays, carbon dioxide, and climate"

In our analysis [Rahmstorf et al., 2004], we arrived at two main conclusions: the data of Shaviv and Veizer [2003] do not show a significant correlation of cosmic ray flux (CRF) and climate, and the authors' estimate of climate sensitivity to CO2 based on a simple regression analysis is questionable. After careful consideration of Shaviv and Veizer's comment, we want to uphold and reaffirm these conclusions. Concerning the question of correlation, we pointed out that a correlation arose only after several adjustments to the data, including shifting one of the four CRF peaks and stretching the time scale. To calculate statistical significance, we first need to compute the number of independent data points in the CRF and temperature curves being correlated, accounting for their autocorrelation. A standard estimate [Quenouille, 1952] of the number of effective data points is urn:x-wiley:00963941:media:eost14930:eost14930-math-0001 where N is the total number of data points and r1, r2 are the autocorrelations of the two series. For the curves of Shaviv and Veizer [2003], the result is NEFF = 4.8. This is consistent with the fact that these are smooth curves with four humps, and with the fact that for CRF the position of the four peaks is determined by four spiral arm crossings or four meteorite clusters, respectively; that is, by four independent data points. The number of points that enter the calculation of statistical significance of a linear correlation is (NEFF− 2), since any curves based on only two points show perfect correlation; at least three independent points are needed for a meaningful result
