Recruit, Respect and Retain: The Impact of the Baby Boomer Nurse on Hospital Workforce Strategy
Hospitals are increasingly concerned about shortages of registered nurses due to the retirement of Baby Boomer nurses. A case study resulted in an internal analysis of Baby Boomer nurses to understand how hospital workforce strategy can effectively retain older nurses. Using an interdisciplinary approach, this primarily qualitative study included an in-depth survey and semi-structured interviews. The hospital was able to identify retention strategies that met the needs of older nurses and the organization through the inclusion of multiple perspectives. The methodology and tools inform, communicate and establish the foundation for a hospital to initiate the development of a strategic plan for retention
Simulation Subsumption or Déjà vu on the Web
Simulation unification is a special kind of unification adapted to retrieving semi-structured data on the Web. This article introduces simulation subsumption, or containment, that is, query subsumption under simulation unification. Simulation subsumption is crucial in general for query optimization, in particular for optimizing pattern-based search engines, and for the termination of recursive rule-based web languages such as the XML and RDF query language Xcerpt. This paper first motivates and formalizes simulation subsumption. Then, it establishes decidability of simulation subsumption for advanced query patterns featuring descendant constructs, regular expressions, negative subterms (or subterm exclusions), and multiple variable occurrences. Finally, we show that subsumption between two query terms can be decided in O(n!n) where n is the sum of the sizes of both query terms
Adjustment of the Elderly in Retirement Homes in Eastern South Dakota
In South Dakota, particularly, growing numbers of older citizens give cause for increasing concern with their problems. While the total population of South Dakota declined by 5.8% between 1930 and 1950, during the same period the number of persons 65 years old and older increased by 49.8%.3 By 1958, 10.1% of the state\u27s total population was 65 years old and older, compared with the national figure of 8.8%. A consideration of the preceding discussion makes understandable the increasing interest in life in the later years. This increased interest has stimulated research, concerned not only with problems like medical care, housing, and finances, but concerned also with more subtle problems involving the maintenance of the older person as an integrated, well-functioning personality
Movement Behavior of Radio-Tagged European Starlings in Urban, Rural, and Exurban Landscapes
Since their intentional introduction into the United States in the 1800s, European starlings (Sturnus vulgaris) have become the fourth most common bird species and a nuisance bird pest in both urban and rural areas. Managers require better information about starling movement and habit-use patterns to effectively manage starling populations and the damage they cause. Thus, we revisited 6 radio-telemetry studies conducted during fall or winter between 2005 and 2010 to compare starling movements (n = 63 birds) and habitat use in 3 landscapes. Switching of roosting and foraging sites in habitat-sparse rural landscapes caused daytime (0900–1500 hours) radio fixes to be on average 2.6 to 6.3 times further from capture sites than either urban or exurban landscapes (P \u3c 0.001). Roosts in urban city centers were smaller (100,000 birds) 6–13 km away in industrial zones. Radio-tagged birds from city-center roosts occasionally switched to the outlying major roosts. A multitrack railroad overpass and a treed buffer zone were used as major roosts in urban landscapes. Birds traveling to roosts from primary foraging sites in exurban and rural landscapes would often pass over closer-lying minor roosts to reach major roosts in stands of emergent vegetation in large wetlands. Daytime minimum convex polygons ranged from 101–229 km2 (x̄ = 154 km2). Anthropogenic food resources (e.g., concentrated animal feeding operations, shipping yards, landfills, and abattoirs) were primary foraging sites. Wildlife resource managers can use this information to predict potential roosting and foraging sites and average areas to monitor when implementing programs in different landscapes. In addition to tracking roosting flights, we recommend viewing high-resolution aerial images to identify potential roosting and foraging habitats before implementing lethal culls (e.g., toxicant baiting)
Adaptation to synchronization in phase-oscillator networks
We introduce an adaptation algorithm by which an ensemble of coupled
oscillators with attractive and repulsive interactions is induced to adopt a
prescribed synchronized state. While the performance of adaptation is
controlled by measuring a macroscopic quantity, which characterizes the
achieved degree of synchronization, adaptive changes are introduced at the
microscopic level of the interaction network, by modifying the configuration of
repulsive interactions. This scheme emulates the distinct levels of selection
and mutation in biological evolution and learning
Efficacy of an Avian Repellent Applied Using Drop Nozzle-Equipped Ground Rigs in Reducing Blackbird Damage to Sunflower
In North Dakota large flocks of blackbirds feed on ripening crops, after breeding and prior to migration, resulting in an annual damage estimate averaging $3.5 million for sunflower. Since the repellent needs to be ingested to be effective, one obstacle is applying sufficient repellent directly to the sunflower face. Thus, we tested efficacy of an anthraquinone-based repellent when applied via drop-nozzle to sunflower using enclosed blackbirds in a semi-natural field setting. We used a ground-rig equipped with 360 Undercover® drop nozzle sprayers to apply 20 gal/ac of solution to sunflower plots with a product application rate of 1.0 gal/ac (13% AQ). To test efficacy, we installed bird enclosures (12 x 13 x 10 ft) to house 10 captive, male red-winged blackbirds (Agelaius phoeniceus) for 23 days on 10 treated and 10 untreated plots. The repellent did not cause birds to consume more alternative diet (i.e., red milo). Sunflower yield did not differ between treated and untreated enclosures as a result of blackbird damage. Variation in the amount of repellent reaching the face of the sunflower and subsequent residues was a limitation of the application method. Efficacy may be improved by increasing the application rate or repellent in the tank mixture, but sprayer technology and economic limitations related to repellent costs need to be considered. Future studies should aim to optimize the amount of product in tank mixtures and the repellent formulation as designed for specific pests and crops
Abanilla y Jumilla en la Corona catalano-aragonesa (s. XIV)
"Homenaje al Profesor Juan Torres Fontes", Murcia, 1987, pp. 477-490.Estudia los problemas entre la Corona catalanoaragonesa y Castilla después de la sentencia arbitral de Torrellas, que puso fin a la guerra entre ambos estados dividiendo el reino de Murcia entre ambos; había que establecer sobre el terreno los límites comunes indicados por la sentencia. Hubo controversia sobre la jurisdicción de Jumilla y de Abanilla o Favanella, que correspondían en principio a la Corona de Aragón, pero que se perdieron finalmente, Abanilla en 1348 y Jumilla durante la guerra de Castilla contra la Corona catalanoaragonesa, conocida como guerra de los dos Pedros (1356-1369). El trabajo se ha reeditado después en M. T. FERRER I MALLOL, Entre la paz y la guerra. La Corona Catalano-aragonesa y Castilla en la Baja Edad Media, Barcelona, Institución Milá y Fontanals.

Macro- and micro-strain in GaN nanowires on Si(111)
We analyze the strain state of GaN nanowire ensembles by x-ray diffraction.
The nanowires are grown by molecular beam epitaxy on a Si(111) substrate in a
self-organized manner. On a macroscopic scale, the nanowires are found to be
free of strain. However, coalescence of the nanowires results in micro-strain
with a magnitude from +-0.015% to +-0.03%.This micro-strain contributes to the
linewidth observed in low-temperature photoluminescence spectra
