    Initial treatment options comprise rest, cervical immobilization, anti-inflammatory drugs (nonsteroidal and steroidal), pain relievers (including muscle relaxants and antiepileptics), and physical therapy (strength of recommendation [SOR]: B, cohort studies). As many as 60% of patients who fail initial treatments report long-term pain relief with epidural corticosteroid injections (SOR : C, case series)

    Contemplating Mindfulness at Work: An Integrative Review

    Get PDF
    Mindfulness research activity is surging within organizational science. Emerging evidence across multiple fields suggests that mindfulness is fundamentally connected to many aspects of workplace functioning, but this knowledge base has not been systematically integrated to date. This review coalesces the burgeoning body of mindfulness scholarship into a framework to guide mainstream management research investigating a broad range of constructs. The framework identifies how mindfulness influences attention, with downstream effects on functional domains of cognition, emotion, behavior, and physiology. Ultimately, these domains impact key workplace outcomes, including performance, relationships, and well-being. Consideration of the evidence on mindfulness at work stimulates important questions and challenges key assumptions within management science, generating an agenda for future research

    The atmospheres of the hot-Jupiters Kepler-5b and Kepler-6b observed during occultations with Warm-Spitzer and Kepler

    This paper reports the detection and the measurements of occultations of the two transiting hot giant exoplanets Kepler-5b and Kepler-6b by their parent stars. The observations are obtained in the near infrared with Spitzer Space Telescope and at optical wavelengths by combining more than a year of Kepler photometry. The investigation consists of constraining the eccentricities of these systems and of obtaining broad band emergent spectra for individual planets. For both targets, the occultations are detected at 3 sigma level at each wavelength with mid-occultation times consistent with circular orbits. The brightness temperatures of these planets are deduced from the infrared observations and reach T=1930+/-100K and T=1660+/-120K for Kepler-5b and Kepler-6b respectively. We measure optical geometric albedos A_g in the Kepler bandpass and find A_g=0.12+/-0.04 for Kepler-5b and A_g=0.11+/-0.04 for Kepler-6b leading to an upper limit for the Bond albedo of A_B < 0.17 in both cases. The observations for both planets are best described by models for which most of the incident energy is redistributed on the dayside, with only less than 10% of the absorbed stellar flux redistributed to the night side of these planets. The data for Kepler-5b favor a model without a temperature inversion, whereas for Kepler-6b they do not allow distinguishing between models with and without inversion.Comment: 26 pages, 18 figures, 3 tables, submitted to Ap

    Low False-Positive Rate of Kepler Candidates Estimated From A Combination Of Spitzer And Follow-Up Observations

    (Abridged) NASA's Kepler mission has provided several thousand transiting planet candidates, yet only a small subset have been confirmed as true planets. Therefore, the most fundamental question about these candidates is the fraction of bona fide planets. Estimating the rate of false positives of the overall Kepler sample is necessary to derive the planet occurrence rate. We present the results from two large observational campaigns that were conducted with the Spitzer telescope during the the Kepler mission. These observations are dedicated to estimating the false positive rate (FPR) amongst the Kepler candidates. We select a sub-sample of 51 candidates, spanning wide ranges in stellar, orbital and planetary parameter space, and we observe their transits with Spitzer at 4.5 microns. We use these observations to measures the candidate's transit depths and infrared magnitudes. A bandpass-dependent depth alerts us to the potential presence of a blending star that could be the source of the observed eclipse: a false-positive scenario. For most of the candidates (85%), the transit depths measured with Kepler are consistent with the depths measured with Spitzer as expected for planetary objects, while we find that the most discrepant measurements are due to the presence of unresolved stars that dilute the photometry. The Spitzer constraints on their own yield FPRs between 5-40%, depending on the KOIs. By considering the population of the Kepler field stars, and by combining follow-up observations (imaging) when available, we find that the overall FPR of our sample is low. The measured upper limit on the FPR of our sample is 8.8% at a confidence level of 3 sigma. This observational result, which uses the achromatic property of planetary transit signals that is not investigated by the Kepler observations, provides an independent indication that Kepler's false positive rate is low.Comment: 33 pages, 16 figures, 3 tables; accepted for publication in ApJ on February 7, 201

    Autistic College Students and COVID-19: Anxiety, Support Needs and Responses by Specialized Programs

    Get PDF
    Providing resources and support to college students during the COVID-19 global pandemic has produced unique challenges for all students, particularly those with autism. In March 2020, halfway through the spring term, the COVID-19 global pandemic forced most institutions of higher education across the country to move all instruction and support to an online, remote format, including those for students with autism. Colleges and autism support programs are now grappling with how to effectively support students amid a global pandemic. Yet there is little information available about how students’ needs have changed with this new environment. In this exploratory study, 76 college students with autism from across the country answered a series of questions (both Likert scale and open-ended) about their anxieties related to COVID-19 and attending college. The data were analyzed using descriptive statistics and thematic analysis. Results revealed that students are most anxious about getting sick or spreading COVID-19 to others and least anxious about wearing masks and needing to socially distance. This paper also profiles the adjustments made to several college autism support programs (led by the authors) in order to accommodate the changes to college campuses and the impact on student needs. The survey results and recent experiences across programs will inform recommendations for colleges as they build toward more inclusive, supportive campus environments and respond to crises like the pandemic
