    The Present Status of the Birds of Hawaii

    The great expanses of open ocean that separate the Hawaiian Islands from the major continental land masses of North America and Asia resulted in the evolution of a number of unique landbirds. Unfortunately, a higher percentage of species of birds have become extinct in Hawaii than in any other region of the world. Approximately 40 percent of the endemic Hawaiian birds are believed to be extinct, and 25 of the 60 birds in the 1968 list of "Rare and Endangered Birds of the United States" are Hawaiian ("Rare and Endangered Fish and Wildlife of the United States, 1968 edition," Bureau of Sport Fisheries and Wildlife, Washington, D. C.). Most of the native birds of Oahu have long been extinct, and few native landbirds are to be found on any of the main islands below 3,000 feet elevation. Three general groups of birds are found in Hawaii today: endemic, indigenous, and introduced

    Improving the Convergence of an Iterative Algorithm Proposed By Waxman

    In the iterative algorithm recently proposed by Waxman for solving eigenvalue problems, we point out that the convergence rate may be improved. For many non-singular symmetric potentials which vanish asymptotically, a simple analytical relationship between the coupling constant of the potential and the ground state eigenvalue is obtained which can be used to make the algorithm more efficient

    The Effect of Unmet Expectations of Information Quality on Post-Acceptance Workarounds among Healthcare Providers

    Electronic health record (EHR) systems have the capacity to aid clinical decision making by providing timely and relevant information about patients. However, providers’ lack of access to complete and up-to-date information in the required format hinders their ability to make timely decisions and often leads to misdiagnosis or redundant, duplicate tests. This research evaluates the extent to which pre-adoption information quality expectations are met and their effect on post-adoption satisfaction with an EHR system in terms of information quality and the workarounds that they may generate. The hypotheses were empirically tested through analysis of the responses of 64 healthcare stakeholders. The results indicate that lower information quality was perceived post-adoption than was expected at pre-adoption of the EHR system. Ultimately, workarounds were found largely to be a direct result of dissatisfaction with the EHR system. The results have implications for remedies to workarounds in terms of policy, training, and EHR system features modifications

    Revisiting the Technology Challenges and Proposing Enhancements in Ambient Assisted Living for the Elderly

    Several social and technical trends support the elderly’s desire to live independently in their preferred environment, despite their increasing medical needs, and enhance their quality of life at home. Ambient-assisted living (AAL) has the capabilities to support the elderly and to decrease their dependency on formal or informal caregivers. We provide a review of the technological challenges that were identified as inhibiting factors in the past decade and then present recent technological advances, e.g., cloud computing, machine learning, artificial intelligence, the Internet of Things. We also fill the gap in the current literature in regard to specific AAL solutions and propose fourth-generation AAL technology design. We find that most informal caregivers are family members who are medically untrained and that the use of advanced analytical processes on AAL-generated data could significantly increase symptom identification. We also present the implications and remaining challenges along with recommendations for future research

    A Modified Version of the Waxman Algorithm

    Full text link
    The iterative algorithm recently proposed by Waxman for solving eigenvalue problems, which relies on the method of moments, has been modified to improve its convergence considerably without sacrificing its benefits or elegance. The suggested modification is based on methods to calculate low-lying eigenpairs of large bounded hermitian operators or matrices
