Making the Abstract Straightforward: A Pilot of Immersive VR in an Allied Health Program of Study

[EN] Emerging technologies in education are offering new tools for teaching and learner engagement. Today’s study and practice can include use of digital technologies far beyond looking at a flat screen: virtual reality, augmented reality, interactive 3D objects and 360 video can provide immersive and impactful teaching and learning. There are a variety of definitions for these “realities” but the overarching impact is one of powerful, immersive, visual learning. Immersive virtual reality in a learner-centric environment can provide more presence and engagement for students, enabling the possibility of enhanced learning experiences relative to conventional classroom practices. This paper presents early results of a pilot study leveraging the possibilities of VR technology in service to an existing program of study in allied health services:graduates surveyed report high degrees of confidence in course materials learned by means of the custom VR components developed, reporting the adjunct course materials substantially helped learners in understanding otherwise difficult to grasp concepts of the course.This project was made possible in part by the Institute of Museum and Library Services through the Library Services and Technology Act.Colegrove, P.; Westergard, T.

COMM 1311: Fundamentals of Speech Communication

This OER packet contains the course materials for COMM 1311: Fundamentals of Speech Communication that introduce you to why do we/I need to take a public speaking course. The answer is also always the same. “Because it is required.” However, you the reader, and us as the authors/editors, know that this doesn’t answer the question. The real answer can be complicated, but this author/editor believes that the skills gained by public speaking will help you in any field, despite whether or not you end up working in a field that requires public speaking.https://digitalcommons.pvamu.edu/pv-open-education-resources/1009/thumbnail.jp

The New Realities of Voting by Mail in 2016

The vote-by-mail process can be more convenient for voters who are unable or unwilling to contend with lines at polling places on Election Day. However, voting by mail is not a voting option without risk. Outdated laws, new administrative policies, and the realities of the political process today introduce obstacles voters may not be aware of. Without recognizing that voting by mail in 2016 is very different than in years past, voters are more likely to unwittingly disenfranchise themselves

High-fidelity single-shot readout for a spin qubit via an enhanced latching mechanism

The readout of semiconductor spin qubits based on spin blockade is fast but suffers from a small charge signal. Previous work suggested large benefits from additional charge mapping processes, however uncertainties remain about the underlying mechanisms and achievable fidelity. In this work, we study the single-shot fidelity and limiting mechanisms for two variations of an enhanced latching readout. We achieve average single-shot readout fidelities > 99.3% and > 99.86% for the conventional and enhanced readout respectively, the latter being the highest to date for spin blockade. The signal amplitude is enhanced to a full one-electron signal while preserving the readout speed. Furthermore, layout constraints are relaxed because the charge sensor signal is no longer dependent on being aligned with the conventional (2, 0) - (1, 1) charge dipole. Silicon donor-quantum-dot qubits are used for this study, for which the dipole insensitivity substantially relaxes donor placement requirements. One of the readout variations also benefits from a parametric lifetime enhancement by replacing the spin-relaxation process with a charge-metastable one. This provides opportunities to further increase the fidelity. The relaxation mechanisms in the different regimes are investigated. This work demonstrates a readout that is fast, has one-electron signal and results in higher fidelity. It further predicts that going beyond 99.9% fidelity in a few microseconds of measurement time is within reach.Comment: Supplementary information is included with the pape

Response of Sorghum Enhanced in Monolignol Biosynthesis to Stalk Rot Pathogens

To increase phenylpropanoid constituents and energy content in the versatile C4 grass sorghum (Sorghum bicolor [L.] Moench), sorghum genes for protiens related to monolignol biosynthesis were overexpressed: SbMyb60 (transcriptional activator), SbPAL (phenylalanine ammonia ase), Bmr2 (4-coumarate: CoA ligase), and SbC3H (coumaroyl shikimate 3-hydroxylase). Overexpression lines were evaluted for responses to stalk pahtogens under greenhouse and field conditions. Greenhouse-grown plants were inoculated with Fusarium thapsinum (Fusarium stalk rot) and Macrophomia phaseolina (charocal rot), which cause yield-reducing diseases. F. thapsinum-inoculated overexpression plants had mean lesion lengths not significantly different than wild-type, except for significantly smaller lesions on two of three SbMyb60 and one of two SbCCoAOMT lines. M. phaseolina-inoculated expression lines had lesions not significantly different from wild-type except one SbPAL line (of two lines studied) with mean lesion lengths significantly larger. Field-grown SbMyb60 and SbCCoAOMT overexpression plants were inoculated with F. thapsinum. Mean lesions of SbMyb60 lines were similar to wild-type, one SbCCoAOMT had larger lesions, whereas the other line was not significantly different than wild-type. Because overexpression of SbMyb60, Bmr2, or SbC3H may not render sorghum more supceptible to stalk rots, these lines may provide sources for development of sorghum with increased phenylpropaniod concentrations

Mapping of reporting guidance for systematic reviews and meta-analyses generated a comprehensive item bank for future reporting guidelines

Objectives: The aim of the study was to generate a comprehensive bank of systematic review (SR) reporting items to inform an update of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2009 statement. Methods: We searched the Enhancing the QUAlity and Transparency Of health Research Network library in May 2019 to identify all reporting guidelines for SRs that were published after 2009, regardless of the scope of the guideline. We also conducted a selective review of four guidance manuals for SRs, three tools for assessing the risk of bias in SRs, six meta-research studies evaluating the reporting quality of SRs using a tailored checklist, and five reporting guidelines for other study designs. One author screened and selected sources for inclusion, extracted reporting guidance from sources, and mapped guidance against the PRISMA 2009 checklist items. Results: We included 60 sources providing guidance on reporting of SRs and meta-analyses. From these, we collated a list of 221 unique reporting items. Items were categorized into title (four items), abstract (10 items), introduction (12 items), methods (111 items), results (61 items), discussion (12 items), funding and conflicts of interest (four items), administrative information (three items), and data availability (four items). This exercise generated 175 reporting items that could be added to the guidance in the PRISMA 2009 statement. Conclusion: Generation of a comprehensive item bank through review and mapping of the literature facilitates identification of missing items and those needing modification, which may not otherwise be identified by the guideline development team or from other activities commonly used to develop reporting guidelines

Revisiting the Applicability of Adult Early Post-Operative Nausea and Vomiting Risk Factors for the Paediatric Patient: A Prospective Study Using Cotinine Levels in Children Undergoing Adenotonsillectomies

Background and Aims: Post-operative vomiting (POV) in children remains a significant clinical problem. This prospective study aims to investigate the applicability of well-established adult early post-operative nausea and vomiting (PONV) risk factors on paediatric POV after adenotonsillectomies under regulated anaesthetic conditions. Methods: After Institutional Review Board approval, 213 children aged 3–10-year-old were enrolled. The participants had pre-operative questionnaires completed, followed protocolised anaesthetic plans and had saliva analysed for cotinine. The primary outcomes were POV as correlated with age, gender, family or personal history of PONV, motion sickness history, opioid use, surgical time, anaesthetic time and environmental tobacco smoke (ETS) exposure, as assessed by cotinine levels and questionnaire reports. Data on analgesics, antiemetics and POV incidence before post-anaesthesia care unit discharge were collected. Statistical analysis was done through multiple logistic regression. Results: A total of 200 patients finalised the study. Early POV occurred in 32%. Family history of PONV (odds ratio [OR] = 5.3, P \u3c 0.01) and motion sickness history (OR = 4.4, P = 0.02) were highly significant risk factors. Age reached borderline statistical significance (OR = 1.4, P = 0.05). None of the other factors reached statistical significance. Conclusion: Early POV occurs frequently in paediatric patients undergoing adenotonsillectomies. In this paediatric-aged group, the incidence of POV was affected by the family history of PONV, and history of motion sickness. Age, female gender, opioid use, surgical and anaesthetic times did not affect the incidence of POV. ETS exposure, as assessed by cotinine levels and questionnaire reports, had no protective effect on early paediatric POV
