    Flipped classrooms are increasingly recommended by scholars of teaching and learning, and some have argued that active learning is the key ingredient in this model’s success. This paper describes the creation and implementation of online guided case study scenarios using the test function of a learning management system, as well as evaluation of their effectiveness based on (a) performance of students on separate graded case study assignments and (b) student self-reflection of learning and feedback elicited in an end-of-course survey. The case studies were developed for use in a master’s level speech-language pathology course on aural rehabilitation that occurs during the summer semester

    Students with reading impairments, including dyslexia, account for the largest proportion of students receiving special education services in the United States (NCES, 2016). Developmental dyslexia is characterized by slow and inaccurate word decoding (Lyon et al., 2003). This word decoding difficulty results from deficits in phonological awareness, a sound-based skill (Swan & Goswami, 1997). Classrooms are known to have high levels of background noise and are inconsistent with recommendations for optimal listening (Picard & Bradley, 2001) or accepted standards (ASHA, n.d.). Furthermore, degraded acoustic conditions have been related to poorer performance on speech-recognition tasks even for children with normal hearing (Finitzo-Hieber & Tillman, 1978; Nabelek & Pickett, 1974) and the impact of classroom noise on academic performance may be greater for children with special educational needs (Shield & Dockrell, 2008). FM systems are devices that enhance the signal-to-noise ratio in noisy environments with high amounts of background noise, such as classrooms, and allow the listener clear access to the teacher’s voice without also amplifying background noise. A limited amount of existing research on the use of FM systems for children with normal hearing suggests that use of amplification technology is associated with academic and social advantages. Provision of FM systems to students with dyslexia results in increased teacher rating and objective measurement of reading skills in a classroom setting (Hornickel et al., 2012; Purdy et al., 2009), but the specific effects of FM system use on phonological awareness skills has not been evaluated. This study investigated the benefit of an FM system during phonological awareness intervention in two studies. Study 1 evaluated the effects of utilizing an FM system during phonological awareness intervention for students at risk for dyslexia with phonological awareness weaknesses in a classroom setting. Study 2 investigated the acquisition of phonological awareness skills targeted during a virtual intervention with simulated classroom noise compared to a condition with a simulated benefit of a classroom-based FM system. In Study 1, four participants received in-person phonological awareness intervention in small groups during the school day. They were assigned to wear an FM system during lessons targeting one skill; during lessons targeting the other skills they received the intervention alone. In Study 2, three participants completed one-on-one phonological awareness intervention through Zoom. They were assigned to learn one skill with simulated classroom noise and another with the simulated benefit of a classroom FM system. Both studies utilized adapted alternating treatment single-case designs and assessed performance using daily assessments on the phonological awareness skills targeted during intervention and one additional phonological awareness skill. In Study 1, two participants demonstrated quicker and more pronounced improvement on the skill learned while wearing the FM system, suggesting FM systems show promise as a tool to use during phonological awareness training. In Study 2, two participants made gains on the phonological awareness skills assessed. However, a difference was not evident between skills learned in the simulated classroom FM and simulated classroom noise condition. The results of Study 1 indicate that FM systems show promise during phonological awareness instruction. However, the finding from Study 2 that simulation of the signal-to-ratio of FM systems was not associated with improved performance compared to simulated classroom noise suggests that aspects of FM systems beyond the increased signal-to-noise ratio alone may be responsible for the benefit they provided. Additionally, findings from Study 2 indicate that virtual phonological awareness instruction holds promise as a method of delivery

    Guidelines created by the Joint Committee on Infant Hearing ([JCIH], 2019) were designed to aid in the early identification of infant hearing loss. Despite these guidelines, a quarter of children who fail their initial screening are lost to the follow-up process and many more do not receive care in line with the 1-3-6 guidelines (Centers for Disease Control and Prevention [CDC], 2018; JCIH, 2019). To acquire more information about the experiences of families and identify specific barriers to timely diagnosis and intervention, interviews were conducted with 13 parents of children who are deaf or hard of hearing whose children were enrolled in a larger longitudinal study. These interviews revealed common themes regarding delayed identification, frustrations about timely intervention, and confusion when choosing communication modalities. Common themes amongst families who felt well-supported were also identified

    Patient satisfaction in shoulder arthroscopy: telemedicine versus clinic follow-up visits

    Background The use of telemedicine for postoperative visits is increasing, especially in rural areas. Few studies have investigated its use for arthroscopic shoulder patients. This study aims to evaluate patient satisfaction with telemedicine for postoperative clinic visits following arthroscopic shoulder procedures in a rural setting. Methods Patients were prospectively enrolled using the following exclusion criteria: 0.05). Patient satisfaction did not vary significantly based on care by the surgeon, concerns being addressed, thoroughness of visit, overall clinical assessment at a prior visit, and improvements in pain and physical function (all p>0.05). Among patients who opted out of telemedicine visits, the most common reason was a preference to meet in-person but these patients agreed that telemedicine visits are a good idea. Conclusions Regardless of type of follow-up, individuals reported similar levels of satisfaction with treatment during the visit and improvements in pain and physical function

    CamTrapAsia: a dataset of tropical forest vertebrate communities from 239 camera trapping studies

    Get PDF
    Information on tropical Asian vertebrates has traditionally been sparse, particularly when it comes to cryptic species inhabiting the dense forests of the region. Vertebrate populations are declining globally due to land-use change and hunting, the latter frequently referred as “defaunation.” This is especially true in tropical Asia where there is extensive land-use change and high human densities. Robust monitoring requires that large volumes of vertebrate population data be made available for use by the scientific and applied communities. Camera traps have emerged as an effective, non-invasive, widespread, and common approach to surveying vertebrates in their natural habitats. However, camera-derived datasets remain scattered across a wide array of sources, including published scientific literature, gray literature, and unpublished works, making it challenging for researchers to harness the full potential of cameras for ecology, conservation, and management. In response, we collated and standardized observations from 239 camera trap studies conducted in tropical Asia. There were 278,260 independent records of 371 distinct species, comprising 232 mammals, 132 birds, and seven reptiles. The total trapping effort accumulated in this data paper consisted of 876,606 trap nights, distributed among Indonesia, Singapore, Malaysia, Bhutan, Thailand, Myanmar, Cambodia, Laos, Vietnam, Nepal, and far eastern India. The relatively standardized deployment methods in the region provide a consistent, reliable, and rich count data set relative to other large-scale pressence-only data sets, such as the Global Biodiversity Information Facility (GBIF) or citizen science repositories (e.g., iNaturalist), and is thus most similar to eBird. To facilitate the use of these data, we also provide mammalian species trait information and 13 environmental covariates calculated at three spatial scales around the camera survey centroids (within 10-, 20-, and 30-km buffers). We will update the dataset to include broader coverage of temperate Asia and add newer surveys and covariates as they become available. This dataset unlocks immense opportunities for single-species ecological or conservation studies as well as applied ecology, community ecology, and macroecology investigations. The data are fully available to the public for utilization and research. Please cite this data paper when utilizing the data

    Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

    Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference) and obesity (BMI >2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesit

    Quantitative, multiplexed, targeted proteomics for ascertaining variant specific SARS-CoV-2 antibody response

    Get PDF
    Determining the protection an individual has to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants of concern (VoCs) is crucial for future immune surveillance, vaccine development, and understanding of the changing immune response. We devised an informative assay to current ELISA-based serology using multiplexed, baited, targeted proteomics for direct detection of multiple proteins in the SARS-CoV-2 anti-spike antibody immunocomplex. Serum from individuals collected after infection or first- and second-dose vaccination demonstrates this approach and shows concordance with existing serology and neutralization. Our assays show altered responses of both immunoglobulins and complement to the Alpha (B.1.1.7), Beta (B.1.351), and Delta (B.1.617.1) VoCs and a reduced response to Omicron (B1.1.1529). We were able to identify individuals who had prior infection, and observed that C1q is closely associated with IgG1 (r > 0.82) and may better reflect neutralization to VoCs. Analyzing additional immunoproteins beyond immunoglobulin (Ig) G, provides important information about our understanding of the response to infection and vaccination
