Impact of Interprofessional Student Teams at a Remote Area Medical Event in Rural Appalachia

Introduction: Education in interprofessional collaboration is vital to expand healthcare access, especially in areas of higher disparity. To address this need, interprofessional faculty collaborators incorporated undergraduate and graduate health profession students into teams at an annual Remote Area Medical event in rural Appalachia between 2017 and 2020. Purpose: This article evaluates the impact of an interprofessional student teams model on both patient care experience and students’ interprofessional collaboration attitudes and behaviors. Methods: Student volunteers completed pre- and post-event surveys containing questions about demographics, open-ended questions, and questions from two instruments: the Student Perceptions of Interprofessional Clinical Education-Revised Instrument, Version 2 (SPICE-R2) and the Interprofessional Collaborative Competency Attainment Scale-Revised (ICCAS-R). Quantitative data were analyzed statistically; qualitative data thematically. Tally forms collected patient care interventions that were compared to regional health disparities. Two years of survey data and four years of intervention data were analyzed. Results: There was an increase (p \u3c 0.001) in the post-event survey SPICE-R2 factors (teamwork, healthcare outcomes, and roles and responsibilities) in 2020 but not in 2019. ICCAS-R mean post-event composite scores increased (p \u3c 0.05) in both 2019 and 2020. Qualitative coding of open-ended responses revealed interprofessional competency themes and provided event feedback. Over 5,900 health-disparity-focused interventions were completed between 2017 and 2020. Implications: Students participating in interprofessional teams demonstrate changes in attitudes towards the interprofessional approach to care, an improved ability to collaborate interprofessionally, and a positive impact on patient care interventions. The findings allow educators to understand how experiential interprofessional education influences students’ interprofessional attitudes and beliefs while benefitting patient care

Are Thiel-embalmed Cadavers Effective Tools in Educating Medical Students to Perform Knee Arthrocentesis?

INTRODUCTION: The purposes of this study are to determine whether Thiel-embalmed cadavers are an effective educational tool in teaching medical students to perform knee arthrocentesis, to compare the use of Thiel-embalmed cadavers to formalin-embalmed cadavers in arthrocentesis education, and to determine whether the use of Thiel-embalmed cadavers is potentially generalizable to the instruction of other orthopedic procedures. METHODS: Sixty-eight third-year medical students participated in the study. The participants first completed a pre-survey to assess their prior experience with arthrocentesis procedures and Thiel-embalmed cadavers. Participants then attended an instructional session where the knee arthrocentesis procedure was demonstrated on a Thiel-embalmed cadaver. Participants then individually performed the simulated knee arthrocentesis procedure twice: once on a Thiel-embalmed cadaver and once on a formalin-embalmed cadaver. Success of each attempt was determined through the visualization of aspirated joint fluid. Following the laboratory session, each participant completed a post-survey to determine whether the session improved their perceived confidence in performing knee arthrocentesis, if they preferred the use of Thiel-embalmed cadavers or formalin-embalmed cadavers as a teaching tool, and if they believed simulated practice using Thiel-embalmed cadavers would be effective for learning other orthopedic procedural skills. RESULTS: Sixty-eight students participated in the laboratory session and successfully completed both pre- and post-course surveys. 96% of participants reported that they felt confident performing knee arthrocentesis under physician supervision following their participation in the laboratory session (versus 15% of participants in the pre-survey). 96% of participants reported that the Thiel-embalmed cadavers provided a more realistic teaching model than formalin-embalmed cadavers for learning knee arthrocentesis. 100% of participants believed the incorporation of simulated practice using Thiel-embalmed cadavers is an effective method in teaching students to perform knee arthrocentesis. 100% of participants reported that they would participate in future sessions using Thiel-embalmed cadavers to learn and practice other orthopedic procedural techniques. DISCUSSION: This study used a moderate sample size of third-year medical students to provide data regarding the suitability of using Thiel cadavers in arthrocentesis education. Results indicate that Thiel cadavers are effective tools in teaching medical students to perform knee arthrocentesis, that students preferred the Thiel cadavers to the formalin cadavers, and that the use of Thiel cadavers is a safe, engaging, and high-quality teaching modality for demonstrating proper arthrocentesis procedural technique to medical students. Since this study looked specifically at teaching knee arthrocentesis to medical students, it is uncertain whether the benefits of Thiel cadavers are generalizable to the education of other orthopedic procedures and subject groups such as residents, fellows, and practicing physicians. Further studies should be performed to assess whether Thiel cadavers are beneficial in teaching other orthopaedic procedures and if these benefits extend to other subject groups

Listeners feel the beat: Entrainment to English and French speech rhythms

Can listeners entrain to speech rhythms? Monolingual speakers of English and French and balanced English–French bilinguals tapped along with the beat they perceived in sentences spoken in a stress-timed language, English, and a syllable-timed language, French. All groups of participants tapped more regularly to English than to French utterances. Tapping performance was also influenced by the participants’ native language: English-speaking participants and bilinguals tapped more regularly and at higher metrical levels than did French-speaking participants, suggesting that long-term linguistic experience with a stress-timed language can differentiate speakers’ entrainment to speech rhythm

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe

Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe

Development and validation of HERWIG 7 tunes from CMS underlying-event measurements

This paper presents new sets of parameters (“tunes”) for the underlying-event model of the HERWIG7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in HERWIG7, and are obtained from a fit to minimum-bias data collected by the CMS experiment at s=0.9, 7, and 13Te. The tunes are based on the NNPDF 3.1 next-to-next-to-leading-order parton distribution function (PDF) set for the parton shower, and either a leading-order or next-to-next-to-leading-order PDF set for the simulation of MPI and the beam remnants. Predictions utilizing the tunes are produced for event shape observables in electron-positron collisions, and for minimum-bias, inclusive jet, top quark pair, and Z and W boson events in proton-proton collisions, and are compared with data. Each of the new tunes describes the data at a reasonable level, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the dat
