The healthcare system is a complex system which exhibits conditions of uncertainty, ambiguity emergence that incurs incoming patient congestion. Discrete event simulation (FlexSim) is considered as a viable decision support tool in analyzing a system for improvement. Using a data-driven discrete event simulation approach, this paper portrays a comprehensive analysis to maximize the number of patients in an on-campus clinic, located at Mississippi State University. The outcome of the analysis of current system exhibits that deploying a few nurse practitioners results in bottlenecks which decreases the systems’ throughput substantially due to the overall longer patients’ waiting time. Access to the laboratory is characterized through multi-server queuing network, arrival process is followed discrete distributions, and batch sizes and arrival times are stochastic in nature. In an effort to plummet inpatient congestion at the outpatient clinic, by using empirically calibrated simulation model, we will figure out the best balance between the number of the lab technician and incoming patient during working hour. An analysis of optimal solutions is demonstrated, which is followed by recommendation and avenues for future research.
This study investigates the relationship between the personality type and cognitive-metacognitive strategies utilized by test-takers in reading comprehension tests. One hundred undergraduate Iranian English Foreign Learning (EFL) students participated in a reading comprehension test followed by a questionnaire and the Myers & Briggs Type Inventory. The questionnaire consisted of 30 cognitive-metacognitive items (Phakiti, 2003). These questions inquired about the thought process that occurred while completing the test. The 93-item Myers-Brigs Type Indicator (MBTI) questionnaire is a tool that provides individuals with a personality type. The study employed a quantitative data analysis where the input data was analyzed in two ways. First, descriptive statistics were used to describe the sample characteristics, and then a two-way ANOVA was calculated to obtain a general view of the relationship between the variables. The data analysis resulted in the identification of 14 personality types along with three groups of readers distinguished by their reading comprehension test scores as highly successful, moderately successful, or unsuccessful. However, the results suggested that there were no significant relationships between personality types of test-takers and the cognitive-metacognitive strategies utilized during a reading comprehension test. Using a 90 percent Confidence Interval (CI), there was meaningful interaction between the personality traits (Extroversion/Introversion and Judging/Perceiving) of Iranian EFL test-takers and their use of cognitive-metacognitive strategies.
In a wide range of industries and academic fields, artificial intelligence is becoming increasingly prevalent. AI models are taking on more crucial decision-making tasks as they grow in popularity and performance. Although AI models, particularly machine learning models, are successful in research, they have numerous limitations and drawbacks in practice. Furthermore, due to the lack of transparency behind their behavior, users need more understanding of how these models make specific decisions, especially in complex state-of-the-art machine learning algorithms. Complex machine learning systems utilize less transparent algorithms, thereby exacerbating the problem. This survey analyzes the significance and evolution of explainable AI (XAI) research across various domains and applications. Throughout this study, a rich repository of explainability classifications and summaries has been developed, along with their applications and practical use cases. We believe this study will make it easier for researchers to understand all explainability methods and access their applications simultaneously.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
