    Get PDF
    A multi-element rotor blade includes an individually controllable main element and fixed aerodynamic surface in an aerodynamically efficient location relative to the main element. The main element is controlled to locate the fixed aerodynamic surface in a position to increase lift and/or reduce drag upon the main element at various azimuthal positions during rotation

    Dream Self-Reflectiveness as a Learned Cognitive Skill

    Many prominent researchers subscribe to the notion that dreaming is cognitively deficient relative to normal waking consciousness (Foulkes,1983; Hartmann, 1973; Koukkou & Lehman, 1983). Dreams are perceived as massively non-reflective and single-minded as evidenced by their apparent lack of imagination, lack of lucidity (awareness of dreaming while dreaming), and tendency to be forgotten (Rechtschaffen, 1978). The notion of dream ‘isolation’ from other systems of consciousness has been posited by Rechtachaffen as an inescapable conclusion once these characteristics of dreaming have been understood

    Background: Hospitalization offers an optimal environment for ensuring that patients receive evidence-based treatment. An inpatient tobacco treatment program can deliver interventions broadly, but minimal research has examined the impacts of a consult program on inpatient providers. The Nicotine Dependence Program at the University of North Carolina has provided an inpatient tobacco treatment consult service since 2010. Objective: The program sought feedback from inpatient providers to examine factors that prompted tobacco treatment consult orders, the impact on provider counseling behavior, provider satisfaction, and suggested program improvements. Design: Providers who had ordered a tobacco treatment consult received an online anonymous survey. Setting: The University of North Carolina Hospital is an academic medical facility with 803 beds and over 37,000 inpatient admissions annually from all 100 counties in North Carolina. Approximately 20% of these inpatients report current use of any tobacco product. Patients/participants: Medical providers who ordered inpatient tobacco treatment consults from July 2012 to June 2013 (n=265) received the survey, with 118 providers responding (44.5% response rate). Results: Almost all providers reported being satisfied with the consult program and believed it was effective. Key factors in provider satisfaction included ease of accessing the service, saving provider time, and offering patients evidence-based tobacco use treatment. The consult program increased the likelihood of providers prescribing tobacco cessation medications at discharge, as well as following up at post-discharge appointments. Conclusion: This is some of the first research to show provider satisfaction, program usage, and outcomes with an inpatient tobacco treatment program and demonstrates the important impact of implementing tobacco treatment services within hospitals

    This Powerpoint presentation briefly reports on results of an evaluation of Reclaiming Futures Anchorage, which is one of 10 founding Reclaiming Futures projects funded by the Robert Wood Johnson Foundation to create new approaches to help teens in trouble with drugs, alcohol and crime. It partners with courts, treatment facilities, detention facilities, and community to promote new opportunities and standards of care in juvenile justice to improve the improvement of drug and alcohol treatment, expand and coordinate services, and find jobs and volunteer work for young people in trouble with the law.Research sponsored by Anchorage Reclaiming Future

    Credit scores, cardiovascular disease risk, and human capital.

    Credit scores are the most widely used instruments to assess whether or not a person is a financial risk. Credit scoring has been so successful that it has expanded beyond lending and into our everyday lives, even to inform how insurers evaluate our health. The pervasive application of credit scoring has outpaced knowledge about why credit scores are such useful indicators of individual behavior. Here we test if the same factors that lead to poor credit scores also lead to poor health. Following the Dunedin (New Zealand) Longitudinal Study cohort of 1,037 study members, we examined the association between credit scores and cardiovascular disease risk and the underlying factors that account for this association. We find that credit scores are negatively correlated with cardiovascular disease risk. Variation in household income was not sufficient to account for this association. Rather, individual differences in human capital factors—educational attainment, cognitive ability, and self-control—predicted both credit scores and cardiovascular disease risk and accounted for ∌45% of the correlation between credit scores and cardiovascular disease risk. Tracing human capital factors back to their childhood antecedents revealed that the characteristic attitudes, behaviors, and competencies children develop in their first decade of life account for a significant portion (∌22%) of the link between credit scores and cardiovascular disease risk at midlife. We discuss the implications of these findings for policy debates about data privacy, financial literacy, and early childhood interventions

    An economic survey of New Zealand wheatgrowers : survey no. 2

    Get PDF
    This is survey number 2. No. 1 was know as "National wheatgrowers' survey"This Report is the second in an annual series of economic surveys of New Zealand wheatgrowing farms. These surveys have been undertaken by the Agricultural Economics Research Unit at Lincoln College on behalf of Wheat Growers Sub-Section of Federated Farmers of New Zealand Inc. Specific attention has been focused on the physical characteristics of wheatgrowing farms, the area of wheat and other crops sown, wheat yields, cultural practices and costs and returns for the 1977/78 wheat crop. An attempt has also been made to allocate plant and machinery overhead costs to the wheat enterprise on both an historical and current cost basis. The need for current and detailed information from the Survey involved two visits to the farms in the sample; one in the spring following drilling and the second in the autumn after harvest

    Both Constitutive and Infection‐Responsive Secondary Metabolites Linked to Resistance against Austropuccinia psidii (Myrtle Rust) in Melaleuca quinquenervia

    Get PDF
    Austropuccinia psidii is a fungal plant pathogen that infects species within the Myrtaceae, causing the disease myrtle rust. Myrtle rust is causing declines in populations within natural and managed ecosystems and is expected to result in species extinctions. Despite this, variation in response to A. psidii exist within some species, from complete susceptibility to resistance that prevents or limits infection by the pathogen. Untargeted metabolomics using Ultra Performance Liquid Chromatography with Ion Mobility followed by analysis using MetaboAnalyst 3.0, was used to ex-plore the chemical defence profiles of resistant, hypersensitive and susceptible phenotypes within Melaleuca quinquenervia during the early stages of A. psidii infection. We were able to identify three separate pools of secondary metabolites: (i) metabolites classified structurally as flavonoids that were naturally higher in the leaves of resistant individuals prior to infection, (ii) organoheterocyclic and carbohydrate‐related metabolites that varied with the level of host resistance post‐infection, and (iii) metabolites from the terpenoid pathways that were responsive to disease progression re-gardless of resistance phenotype suggesting that these play a minimal role in disease resistance during the early stages of colonization of this species. Based on the classes of these secondary me-tabolites, our results provide an improved understanding of key pathways that could be linked more generally to rust resistance with particular application within Melaleuca. © 2022 by the authors.

    Effect of propranolol on facial processing in autism spectrum disorder

    Get PDF
    Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social interaction deficits, communication impairments, and restricted, repetitive behaviors. ASD, with estimates of incidence as high as 1 in 88 individuals, has a largely unknown etiology. Pharmacological intervention is currently being explored to improve symptoms of ASD, including those in the social domain. Social interaction deficits in this population may include facial processing abnormalities, such as reduced eye contact, and increased fixation on less socially-salient facial regions, such as the mouth. However, there is variability in the degree of these deficits in the current literature. Additionally, it has been previously hypothesized that stress mediates poor facial processing in individuals with ASD. This pilot study examines the effect of propranolol, a nonselective beta-adrenergic antagonist anxiolytic, on facial processing in individuals with ASD and typically developing controls
