    IMPLEMENTATION OF A FALL PREVENTION PROGRAM

    Improving patient safety and outcomes are unequivocal goals of hospital organizations because the business of healthcare would not be possible without our patients. One of the most prevalent reasons patients can experience poor outcomes is due to falls. There are numerous interventions already in place in organizations to prevent and eliminate these patient events, but they still occur. This study aims to provide a practical and structural approach to eliminating patient falls by implementing a fall prevention program. This fall prevention curriculum includes utilization of bedside shift report, safety huddles, and code fall teams

    Transformation of Morphology and Luminosity Classes of the SDSS Galaxies

    We present a unified picture on the evolution of galaxy luminosity and morphology. Galaxy morphology is found to depend critically on the local environment set up by the nearest neighbor galaxy in addition to luminosity and the large scale density. When a galaxy is located farther than the virial radius from its closest neighbor, the probability for the galaxy to have an early morphological type is an increasing function only of luminosity and the local density due to the nearest neighbor (ρn\rho_n). The tide produced by the nearest neighbor is thought to be responsible for the morphology transformation toward the early type at these separations. When the separation is less than the virial radius, i.e. when ρn>ρvirial\rho_n > \rho_{\rm virial}, its morphology depends also on the neighbor's morphology and the large-scale background density over a few Mpc scales (ρ20\rho_{20}) in addition to luminosity and ρn\rho_n. The early type probability keeps increasing as ρn\rho_n increases if its neighbor is an early type. But the probability decreases as ρn\rho_n increases when the neighbor is a late type. The cold gas streaming from the late type neighbor can be the reason for the morphology transformation toward late type. The overall early-type fraction increases as ρ20\rho_{20} increases when ρn>ρvirial\rho_n > \rho_{\rm virial}. This can be attributed to the hot halo gas of the neighbor which is confined by the pressure of the ambient medium held by the background mass. We have also found that galaxy luminosity depends on ρn\rho_n, and that the isolated bright galaxies are more likely to be recent merger products. We propose a scenario that a series of morphology and luminosity transformation occur through distant interactions and mergers, which results in the morphology--luminosity--local density relation.Comment: 14 pages, 7 figures, for higher resolution figures download PDF file at http://astro.kias.re.kr/docs/trans.pdf ; references added and typos in section 3.2 corrected; Final version accepted for publication in Ap

    Varying c cosmology and Planck value constraints

    Full text link
    It has been suggested that by increasing the speed of light during the early universe various cosmological problems of standard big bang cosmology can be overcome, without requiring an inflationary phase. However, we find that as the Planck length and Planck time are then made correspondingly smaller, and together with the need that the universe should not re-enter a Planck epoch, the higher cc models have very limited ability to resolve such problems. For a constantly decreasing cc the universe will quickly becomes quantum gravitationally dominated as time increases: the opposite to standard cosmology where quantum behaviour is only ascribed to early times.Comment: extended versio

    Three new species of \u3ci\u3eCautethia\u3c/i\u3e Grote (Lepidoptera: Sphingidae) from the Lucayan Archipelago and keys to West Indies species

    . Five species of Cautethia Grote (Lepidoptera: Sphingidae) occur in the Lucayan (Bahamas) Archipelago, three of which are new to science. Cautethia simoni Miller, Matthews, and Gott, new species, is described and illustrated from Mayaguana Island, Bahamas, and Providenciales and Grand Turk of the Turks and Caicos Islands. Cautethia gossi Miller, Matthews, and Gott, new species, is described and illustrated from Great Inagua, Bahamas. Cautethia geraceorum Miller, Matthews, and Gott, new species, is described from San Salvador Island. Diagnoses are provided and new island records are reported for the two previously described Bahamas species, Cautethia grotei Edwards and Cautethia exuma McCabe. A taxonomic key based primarily on genitalia is provided for males and known females of the ten described species occurring in the West Indies. COI barcodes were obtained from representative Bahamas specimens and analyzed along with existing barcodes
