The Value of Qualitative Methods in Cross Cultural Education: A Case Study from a First Person Perspective
Get PDFThis paper presents a first-person account of using qualitative research methods to address medical residency education. The results of this project have been published. However, the study's process and its educational impact on the participants have not been well-described. The purpose of this article is to describe the background and conduct of the study itself. A family medicine residency program, the setting for this project, had recently begun accepting international medical graduates (IMGs) who had lived and received medical school education outside of the United States. The author, a faculty member in the residency and a clinical psychologist, and the physician faculty observed residents as they saw patients in the family medicine residency clinic. Concern was expressed about some of the IMG resident physicians’ knowledge base and their ability to develop rapport with patients. In providing instruction in behavioral science, the author and a psychologist colleague noted that some of the IMG residents were confused by aspects of U.S. family life and the educational system. The relationship with clinical instructors and expectations of faculty also differed from the pedagogical norms in U.S. medical education. As a result, a qualitative interview project was undertaken to understand better how these IMG residents were experiencing and interpreting faculty-learner and resident physician-patient interactions. The results were beneficial in multiple ways. First, recognizing that faculty members were interested in their experiences helped develop rapport and trust between the faculty and residents. Providing the project results to the residents helped open discussion about cultural differences in medical education and patient care. For educators who may have difficulty understanding the perspective that learners bring to their education, the process described could be of potential benefit
Potentiality of Biogas Production from Waste in Bangladesh
Get PDFBiogas is treated as a prominent renewable source in the world for mitigating fuel crises in developing countries. Using biogas technology toxic waste can be handled with an anaerobic process helping to generate natural fertilizers. So, it is a major concern for the researchers to find the proper solution by selecting a suitable renewable energy source in the present world. Biogas is treated as a type of biofuel that can be obtained from the fermentation of organic waste. The main goal of this research is to show the potential of a biogas generator in terms of cow dung, vegetable waste, kitchen waste, and poultry to generate biogas. The produced biogas from the decomposition of the organic waste can be utilized in electric power generation to fulfill the power demand of a house. From the analysis, it is seen that cow dung is the most powerful waste for the generation of biogas in comparison to other types of waste. The calculation shows that cow dung is almost 86.75 % more efficient than the kitchen waste and 44.49 % more efficient than the vegetable waste. And some practical data of a biogas power plant has been included to show the potentiality of biogas in the present world

Nonlinear Approximation for Natural Convection Flow Past A Vertical Moving Plate With Nonlinear Thermal Radiation Effect
Get PDFThis piece of work contains significant insight associated with the analysis of fluid transport in the vicinity of a constantly moving vertical plate with nonlinear thermal radiation. The heat transport at the wall surface is assumed to be influenced by convective boundary conditions. Furthermore, thermal transport is considered to be enhanced by nonlinear temperature variation with temperature (NDT). The boundary layer approximation equations are simplified through suitable alteration known as the similarity transformation. The resulting ODEs are translated into the IVP via shooting techniques and then integrated using the RKF45 algorithm in Maple. The impact of the dimensionless parameters dictating the fluid behaviour is demonstrated via graphs and tables. In the cause of the analysis, it is observed that the heat transfer enhances when the fluid flow in the direction +ve x-axis whereas the plate moves in the direction of the -ve x-axis but decreases when the plate and fluid move in the same direction. The skin friction coefficient decreases when the fluid flow is directed toward the +ve x-axis whereas the plate moves toward the -ve x-axis but is enhanced when the plate and the fluid move in the same orientation. The temperature and velocity profiles appreciate with the nonlinear thermal radiation when the motion of the plate and the fluid are on the same axis. The temperature gradient near the wall depreciated gradually due to nonlinear thermal radiation growth but appreciate in the free stream
Nigeria’s Foreign Policy and Insecurity: Addressing the Missing Links and Reoccurring Issues
Get PDFInsecurity is the biggest problem in Africa and nothing meaningful has been done by several sovereign states in Sub-Saharan Africa to stem the tide and its effects on nations all over the region. To this end, security has risen to be the dire need to be considered through the lens of foreign policy as an integral part of public administration and governance in Nigeria. Therefore, this paper specifically explored the missing links that gave rise to the problem of insecurity from foreign policy perspective; and the reoccurring issues that the ebb and flow of her foreign policy posed to Nigerian public space with major focus on Buhari’s Administration. Secondary data was employed to analyse the broad and specific objectives of this paper through a descriptive and explanatory method. The missing link in Nigeria’s foreign policy and security challenges spotted in the analysis are political ideology, globalization, poorly unchecked borderlands, and high rate of migration of criminal elements. The paper discovered some reoccurring issues in Nigeria’s foreign policy and security challenges. The paper concluded that all is not well with the country, because while the protectionist policy under President Buhari to a great extent blocked foreign trade, it left security of borderlands at the mercy of corrupt security personnel. Based on this, all hands must be on deck to exterminate the current tide in the wave of insecurity ravaging the country at all costs
Evaluation of Power Performance of Solar Module Using Two Diode Model with MATLAB Simulation
Get PDFThis paper tries to represent the difference between single diode and two diode photovoltaic models in terms of efficiency simulated by MATLAB. The research activities done earlier had shown a clear preview that the solar cell can act as concentrated solar cell for increasing the conversion efficiency to a great extant so that output power can be improved to a large scale. Here for showing the manner of concentrated solar action double diode model has been calculated for observing the power difference in comparison with the solar cell of single diode as a convenient one. It has been observed that the photovoltaic module with two diode model is observed as highly efficient in comparison with single diode model. And this two diode model can be treated as highly efficient to convert the solar energy in the electric energy. Also, the behavior of power performance is observed practically which is included in this paper. And finally, a comparison has been drawn out to exhibit the verification of power performance for two diode model using MATLAB simulation. The mostly impact factors considered in this paper are solar irradiance and temperature affecting the power output from PV module
Utilization of SGLT-2 Inhibitors in Congestive Heart Failure Management
Get PDFCongestive heart failure (CHF) is a progressive condition where the heart cannot pump blood well enough to keep up with volume demand, which results in decreased oxygen perfusion throughout the periphery and vital body organs. This condition affects over six million Americans and is projected to increase by over 46% by the year 2030. By incorporating evidence from research conducted over the past ten years, several studies demonstrate the benefits of sodium-glucose co-transporter (SGLT-2) inhibitors in managing CHF patients. The glucose-lowering medication works to relieve fluid overload by excreting excess glucose and sodium while also increasing vasodilation and reducing cardiac preload. SGLT-2 inhibitors also have an anti-inflammatory effect that decreases epicardial adipose deposition, which relieves oxidative stress on the heart. In addition to the mainstay of medical management for CHF patients, SGLT-2 inhibitors have reduced exacerbations that are often life-threatening and improved overall quality of life by reducing morbidity and mortality
The Influence of Preparation Parameters on Structural and Optical Properties of N-Type Porous Silicon
Get PDFIn this paper, we describe the formation of macroporous silicon (MPS) formed anodically polarized on n type Si (100) substrates at a constant current density under front side illumination using two electrolytes, HF/Ethanol and HF/Ethanol/H2O2. The effect of adding H2O2 in the solution on the resulting pores were investigated by scanning electron microscopy (SEM), infrared spectroscopy (FTIR), contact angle measurements and UV-vis spectrophotometry. The results showed that for the anodization conditions the MPS formed in peroxide based (H2O2)/HF/Ethanol solution exhibited structures with larger pore size and different pore morphologies depending on the etching time than those formed in HF/Ethanol. The pore density and the pore size of the MPS samples increased with the etching time. The infrared absorption spectrum (FTIR) carried out on the freshly prepared sample indicates that the MPS contains Si-Hx bonds which decrease with increasing the etching time. Finally, measurements of contact angle indicate that the formed MPS samples are highly hydrophobic
Human Factor Drivers of Change Readiness: A Targeted Approach to Change Success
Get PDFThe growing complexity of managing humans during change is evident in the increasing levels of uncertainty and risk. This research aimed to determine which two human factors drive change-ready individuals and to what extent. The researcher used a quantitative cross-sectional survey research design and convenience non-probability sampling method to determine change readiness. The validated change readiness survey was distributed on social media platforms between June 27 and July 9, 2022. The results included data from 112 participants whose average change readiness score was 7.8/10. Human factors that drove change readiness included resourcefulness (47.3%), confidence (34.8%), and optimism (30.4%). Those who were 10/10 change-ready were more likely to be confident (59%), females (93%), in age groups 18 – 25 and 58 – 67 years (30% respectively), and hold Master’s degrees (33%). On average 1.7 human factors drove change at any one time, which increased to 3.5 human factors in those who were most change‑ready. This research confirms a positive relationship between two core human factors and change readiness, namely resourcefulness and confidence. Change-ready individuals driven by resourcefulness and confidence have the potential to be strategic change agents and catalysts for project and change success. The result of this study can be replicated to generate a snapshot of change readiness with minimal effort and inconvenience and help to position the most change-ready individuals in roles of critical importance
Remarks on the Solution of Fractional Ordinary Differential Equations Using Laplace Transform Method
Get PDFIn this work we used the Laplace transform method to solve linear fractional-order differential equation, fractional ordinary differential equations with constant and variable coefficients. The solutions were expressed in terms of Mittag-Leffler functions, and then written in a compact simplified form. As a special case for simplicity, the order of the derivative determined the order of the solution that was obtained. This paper presented several case studies involving the implementation of Fractional Order calculus-based models, whose results demonstrate the importance of Fractional Order Calculus
