    The number of individuals enrolling in postsecondary education with a diagnosed disability is rising. However, the literature reflects a gap between mandated institutional policies and the extent of accommodation use and success. This study examines the use, type, and prevalence of accommodations used by students with disabilities completing occupational therapy fieldwork rotations, as well as the common barriers to accommodation access. Snowball sampling methodology was utilized to send out a 26-item questionnaire to occupational therapists and occupational therapy assistants. Two hundred and ninety-two occupational therapists and occupational therapy assistants answered the questionnaire to identify disability type, disclosure of disabilities, and types of accommodations used during fieldwork. Results indicated that 47 respondents (16.91%) reported having either a visible and/or invisible disability but of those respondents, only 25 (55.56%) disclosed their disability during postsecondary education. Of the respondents who identified having a disability during fieldwork, 22 (51.16%) perceived that their disability presented challenges, while only 17 (38.64%) requested accommodations. As more than half of respondents felt their disability presented challenges during their fieldwork, strategies are suggested to encourage students to feel more comfortable disclosing their disability. Through creating a culture of openness to disabilities and understanding individual student needs, there is a potential to help increase the rate of disclosure of disability and potentially decrease some of the challenges experienced by students with disabilities on fieldwork. Further research is needed to develop guidelines and programming for fieldwork educators on how to best incorporate accommodations into their programs

    Conditional interest rate risk and the cross-section of excess stock returns

    Get PDF
    Differences in excess stock returns can be rationalized by their sensitivities to conditional interest rate risk. Value stocks are particularly sensitive to upside movements in interest rate growth,while growth stocks react strongly to downside movements in interest rate growth. Consistent with the basic asset pricing theory, the upside interest rate risk commands a negative premium which is higher than the premium associated with the downside interest rate risk. Upside beta pertains its explanatory power after controlling for exposure to regular unconditional interest rate and various sources of financial and conditional macroeconomic risk

    The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA-derived Quantities, Data Visualization Tools, and Stellar Library

    Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years of operation (2014 July–2017 July). This is the third data release for SDSS-IV, and the 15th from SDSS (Data Release Fifteen; DR15). New data come from MaNGA—we release 4824 data cubes, as well as the first stellar spectra in the MaNGA Stellar Library (MaStar), the first set of survey-supported analysis products (e.g., stellar and gas kinematics, emission-line and other maps) from the MaNGA Data Analysis Pipeline, and a new data visualization and access tool we call "Marvin." The next data release, DR16, will include new data from both APOGEE-2 and eBOSS; those surveys release no new data here, but we document updates and corrections to their data processing pipelines. The release is cumulative; it also includes the most recent reductions and calibrations of all data taken by SDSS since first light. In this paper, we describe the location and format of the data and tools and cite technical references describing how it was obtained and processed. The SDSS website (www.sdss.org) has also been updated, providing links to data downloads, tutorials, and examples of data use. Although SDSS-IV will continue to collect astronomical data until 2020, and will be followed by SDSS-V (2020–2025), we end this paper by describing plans to ensure the sustainability of the SDSS data archive for many years beyond the collection of data

    COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

    Get PDF
    Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≀ 18 years: 69, 48, 23; 85%), older adults (≄ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

    Opposite effects of perceptual and working memory load on perceptual filling-in of an artificial scotoma

    A target presented on a background of dynamic noise disappears from awareness after a few seconds of maintained peripheral viewing. Whereas the effects of bottom-up factors in such filling-in are well documented, the roles of different top-down functions remain relatively unexplored. Here, we investigated the roles of attention and working memory (WM) by manipulating load in concurrent tasks while participants reported filling-in of a peripheral target. In Experiment 1, increasing perceptual load reduced the probability of filling-in and increased the latency of its occurrence. In Experiment 2, increasing WM load shortened the time before filling-in occurred – the opposite effect to increasing perceptual load. These results demonstrate that different top-down functions may have dissociable effects on filling-in

    Immersive journalism: immersive virtual reality for the first-person experience of news

    Get PDF
    This paper introduces the concept, and discusses the implications of Immersive Journalism, that is the production of news in a form in which people can gain first- 2 person experiences of the events or situation described in news stories. The fundamental idea of Immersive Journalism is to allow the participant, typically represented as a digital avatar, to actually enter a virtually recreated scenario representing the news story. The sense of presence obtained through an immersive system (whether a Cave, head-tracked head-mounted displays (HMD) and online virtual worlds, such as video games and online virtual worlds) affords the participant unprecedented access to the sights and sounds, and possibly feelings and emotions, that accompany the news. The paper surveys current approaches to interactive journalism and the theoretical background supporting claims regarding avatar experience in immersive systems. We also provide a specific demonstration: giving participants the experience of being in an interrogation room in an offshore prison. By both describing current approaches and demonstrating an immersive journalism experience, we open a new avenue for research into how presence can be utilized in the field of news and non-fiction.
