Osteopathic medical students' use of a customized mobile app to supplement ECG lectures for examinations
No full textThis case study investigates the use and outcomes of osteopathic medical students’ use of a customized mobile app called “ECGs by JZ” to supplement classroom teaching of electrocardiogram interpretation. The study employs an explanatory case study design using a constructivist theoretical perspective, integrating quantitative and qualitative data to assess the app’s use and effectiveness on exams and how students perceive using the mobile app to study for exams and use on clinical rotations as a reference tool. The app’s design is grounded in the Technology Acceptance Model (TAM) and cognitive load theory, exploring how mobile learning, or m-learning, tools can supplement medical education in a non-formal setting. The case study involves 507 students from three cohorts of osteopathic medical students in first-year, second-year, and the third-year at Oklahoma State University College of Osteopathic Medicine. Quantitative data includes mobile app access data from all three cohorts and exam data from first-year medical students. Qualitative data is gathered from all three cohorts through the use of a survey questionnaire, assessing student perceptions, motivations, and barriers to using the mobile app. The findings reveal that while the app did not statistically improve exam scores for students who used it versus those who did not, students did perceive it as a valuable study tool. The apps’ interactive features, like quizzes and practice questions, were appreciated for their convenience and ease of use, which were consistent with the TAM. The research highlights the importance of integrating non-formal educational strategies in addition to the formal classroom setting, allowing flexible and readily accessible learning resources. Despite the lack of improved exam outcomes, the positive feedback underscores the potential of a mobile learning tool to help understand and retain complex medical concepts that can be used in other disciplines outside of medicine

Barriers of service delivery of Spanish-speaking communities with Parkinson disease
No full textParkinson Disease (PD) is the second most prevalent neurodegenerative disorder. This disease manifests itself through a diverse array of symptoms that differ across individuals. There is an attempt of published studies that discuss the barriers of service delivery of Spanish-speaking communities in the realm of health care. However, there is currently minimal research conducted related to the barriers that may persist for individuals that are Spanish-speaking individuals with a diagnosis of PD. Therefore, this study seeks to assess existing research by conducting a literature review of nine articles published between 2011- 2023, focusing on identifying unmet needs and barriers of service delivery faced by Spanish-speaking communities with PD. This review examines various studies, including recruitment methods, procedures, and findings from the analyzed data. The results demonstrate there are barriers in access to care that contribute to ongoing disparities within this population. A key observation is a lack of culturally relevant information for effectively delivering patient education. Additionally, there is a need for culturally sensitive care and resources to improve experiences with healthcare professionals for individuals with PD and their families
Development of thermoacoustic metastructures
No full textThe thermoacoustic phenomenon occurs due to an instability caused by acoustic waves propagating in a waveguide, inducing oscillations in a porous stack, the ends of which sustain a thermal gradient. This allows for the conversion of acoustic energy to heat or vice versa without the need for moving parts or expendables. Incorporating thermoacoustic elements into the structural framework of acoustic liners with innovative core geometries can create thermoacoustic metastructures (TAMS) enabling airborne noise mitigation, energy harvesting and environmental sensing. An experimental study on 3D-printed stacks using a benchtop rig was correlated with DeltaEC simulations. 3D-printed stacks generally performed comparably to conventional stacks offering affordability and enabling complex core geometries. Proof-of-concept demonstrations were achieved for energy harvesting and acoustic noise mitigation. An acousto-thermo-electric transduction scheme based on thermoacoustic and Seebeck effects was employed to harvest usable electrical power, achieving 33 mV peak voltage and 19.8 μW output power across a 1 Ω load for 119 dB acoustic excitation at resonance (117.5 Hz). A reduction of approximately 5.28 dB in sound pressure level was measured between the source and termination ends. Informed by these results, a metamaterials-inspired design approach was used to develop novel TAMS, such as spiral and 'pie-slice' resonators, to demonstrate enhanced broadband response and improved power-to-volume ratio in the low-frequency (140 dB) showed viscous heating contributions to deviations from simulations, while increased flow speeds (M>0.1) reduced the temperature gradient due to convective cooling of stack faces. Further, the relationship between acoustic absorption and thermoacoustic temperature gradient was examined. With current additive/ hybrid fabrication processes reaching commercial maturity, TAMS could offer enhanced solutions for aircraft noise mitigation, multifunctional structures for built environments, and energy harvesters/ sensors for remote or harsh locations
Consenting to birth: A policy analysis of consent and respectful obstetric patient care
No full textUser studies have be underrepresented in Explainable AI (XAI) literature. While many papers seek to understand interpretability through Folk Psychology or Theory of Mind explanations, the XAI literature also needs to continue to explore rigorous measures of interpretability from the user standpoint. To accomplish this, we employed a straightforward, accurate learning model for automated allocation of capital from financial time series data, and investigated user reactions to, and ability to interpret, varied explanation strategies. After an initial survey gauging a user’s experience with machine learning models in general, the user engaged in an interactive demonstration with the model. Then, we measured the user’s notions of their own understanding and the model’s interpretability and trustworthiness. Interestingly, text explanations were the only type of explanation that increased user trust in a statistically significant way. At the same time, historical examples pulled from the dataset actually negatively impacted user understanding, and were the only explanation type to do so
Reality of teaching diversity in secondary ELA classrooms
No full textThis paper investigates how teachers navigate education's socio-political climate and incorporate diverse voices into their curriculum while safeguarding their careers. Research shows that diverse and multicultural texts are fundamental for students’ personal growth; however, in the last decade, there has been a rise in challenges against texts, curriculums, and educators that promote these ideals. These challenges include book bans, stripping teachers of their licenses, and various other repercussions. I conducted a qualitative research study using an anonymous online survey. Participants were secondary ELA teachers who have taught for at least one academic year. The data collected in the study provided different reasons why the socio-political climate is in its current state, such as restricted autonomy over a teacher’s curriculum choices and parental backlash over current texts/novel choices. These variables present challenges of not allowing a student’s ability to express their thoughts and explore different perspectives. Further qualitative research is needed to explore this topic on a broader scale and its lasting impacts on education
Evaluating the performance of variably irrigated pecan trees in Oklahoma
No full textIrrigation scheduling using soil moisture can help improve irrigation efficiency and pecan production. Soil water content, stem water potential, and pecan production of variably irrigated pecan trees were monitored for two years (2022-2023) at a research orchard in central Oklahoma. The pecan root water uptake distribution and pecan water use were estimated using soil water content data, and the pecan yield, pecan quality, and leaf nutrient data were measured for each growing season. The root water uptake distribution revealed that the effective root zone for the pecan trees in a fine sandy loam soil was located in the top 40-50 cm of the soil and the water extraction that took place below 50 cm was minimal (less than 5% of the total uptake). Irrigation treatments had a relatively small impact on the distribution of root water uptake. Trees that received no irrigation exhibited a slight increase in water extraction deeper in the soil. The estimated evapotranspiration (ET) using the soil water content data was considerably smaller than the estimated ET that was obtained from two other independent sources that quantify ET based on weather data and satellite remote sensing. Pecan yields were significantly affected by the alternate bearing season with a decrease in yields up to 58%. Altogether, the pecan yields varied each year, but another year of data should provide more insight towards the effect of irrigation on pecan yields. Irrigation had an instant impact on pecan quality by showing an increase in nut weight (+0.6 g/tree) for pecans located in irrigated trees but did not have an instant impact on the quantity (or yield) of pecans produced. The leaf nutrient data was slightly affected from the irrigation as leaf nutrient insufficiencies occurred more frequently for non-irrigated treatments
Building and implementing an economical construction equipment simulator as a virtual reality tool in the classroom
No full textVirtual reality is a growing technology topic within the construction industry. Virtual reality cannot only provide entertainment, but it can be used for educational learning and training sessions. One key component of virtual reality incorporated into training sessions focuses on the simulation aspects where the environmental around a person imitates close-to real life conditions. Virtual reality simulations can take on many different forms such as a game, role-play, or even a training activity. Virtual reality through the development of construction equipment simulators has been used to help train construction equipment operators. Yet, the affordability of these simulators may not be within the budget of a company or educational institution. This paper discusses the basic components of a construction equipment simulator and provides insights into how a more economical affordable simulator may be built for the use of educational purposes.Fire, Construction and Emergency Managemen
Application of potential flow solvers in micro air vehicle development for the use in atmospheric data collection
No full textThis study aims to assess the capability of potential flow solvers in predicting the aerodynamic performance of micro air vehicles (MAVs) by comparing the accuracy of traditional flow solvers with results obtained from SolidWorks Flow Simulation. Additionally, it includes a comparison of these computational findings with data gathered from wind tunnel tests, providing a practical benchmark for evaluating their real-world applicability. This study examined the effectiveness of potential flow solvers for lower Reynolds number, low aspect ratio wings. OpenVSP, XFLR5/XFOIL, and SolidWorks Flowsim were used to compare against experimental test data. Reynolds numbers tested ranged from 70,000 to 200,000. Wing planforms tested included Rectangular, Elliptical, and Inverse Zimmerman planforms. All of these wings had a cambered plate airfoil. Results showed that while the lower-order tools such as OpenVSP were not capable of providing realistic data, SolidWorks FlowSim provided data that closely followed the data used for reference. SolidWorks FlowSim generated accurate data for low Reynolds numbers low aspect ratio cambered wings
