Financial Outcomes From Selection Of Insurance Intervals, Shana Anderson Stewart

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The purpose of this paper is to demonstrate the potential value of enrolling in rainfall-index for pasture, rangeland, and forage insurance for Utah producers. A stochastic optimization model is used to identify the optimal selection of insurance intervals that will provide the maximum indemnity payments less premiums. Four Utah counties were selected for analysis. Results indicate that positive returns will occur greater than 60% of the time in all counties with the selected insurance intervals. The optimal months to insure varied in each county.

Adjusting For Guessing And Applying A Statistical Test To The Disaggregation Of Value-Added Learning Scores, Ben O. Smith, Jamie Wagner

Economics Faculty Publications

In 2016, Walstad and Wagner developed a procedure to split pre-test and post-test responses into four learning types: positive, negative, retained, and zero learning. This disaggregation is not only useful in academic studies; but also provides valuable insight to the practitioner: an instructor would take different mitigating actions in response to zero versus negative learning. However, the original disaggregation is sensitive to student guessing. This article extends the original work by accounting for guessing and provides adjusted estimators using the existing disaggregated values. Further, Monte Carlo simulations of the adjusted learning type estimates are provided. Under certain assumptions, an instructor …

Performance Evaluation Of Logistic Regression, Linear Discriminant Analysis, And Classification And Regression Trees Under Controlled Conditions, Cahit Polat

Electronic Theses and Dissertations

Logistic Regression (LR), Linear Discriminant Analysis (LDA), and Classification and Regression Trees (CART) are common classification techniques for prediction of group membership. Since these methods are applied for similar purposes with different procedures, it is important to evaluate the performance of these methods under different controlled conditions. With this information in hand, researchers can apply the optimal method for certain conditions. Following previous research which reported the effects of conditions such as sample size, homogeneity of variancecovariance matrices, effect size, and predictor distributions, this research focused on effects of correlation between predictor variables, number of the predictor variables, number of …

The Effects Of Auditory Verbal Hallucinations On Social-Behavioral-Functioning And Mental Status: Perceptions Among Mental Health Social Workers, Zachary Robert Eckert

Electronic Theses, Projects, and Dissertations

Auditory Verbal Hallucinations (AVH) are a generally distressing phenomena that can have a negative impact on the quality of life of the experiencer. Furthermore, individuals diagnosed with psychotic disorders often display deficits in social/cognitive domains. Despite this, little is known about how AVHs directly affect social functioning and mental status. Because of this dearth of information, exploratory research is needed to generate potential avenues for future experimental research. Qualitative themes about how AVHs influence behavior were derived from interviews with mental health social workers. Eight primary domains were identified: Behavior, social ability, observable traits, voice plasticity, life difficulty, beneficial auditory …

A Computational Model Of Team-Based Dynamics In The Workplace: Assessing The Impact Of Incentive-Based Motivation On Productivity, Josef Di Pietrantonio

Electronic Theses and Dissertations

Large organizations often divide workers into small teams for the completion of essential tasks. In an effort to maximize the number of tasks completed over time, it is common practice for organizations to hire workers with the highest level of education and experience. However, despite capable workers being hired, the ability of teams to complete tasks may suffer if the workers' individual motivational needs are not satisfied.

To explore the impact of incentive-based motivation on the success of team-based organizations, we developed an agent-based model that stochastically simulates the proficiency of 100 workers with varying abilities and motive profiles to …

Dispensing Medical Countermeasures In Public Health Emergencies Via Home Health Agencies And Points Of Distribution, Anna Hudgeons

Industrial Engineering Undergraduate Honors Theses

A major concern regarding emergency preparedness on the state government level involves the handling and dispensing of the Strategic National Stockpile (SNS) of medicinal supplies. Each state is required to update and maintain a plan of action for dispensing SNS materials that would effectively provide care to the state’s population in times of distress. This research evaluates a state’s ability to dispense an adequate amount of medicine to her population in a timely manner, specifically after it has been received by the state government. Although simulation modeling has previously been utilized to replicate the dispensing process at pre-designated points of …

Hierarchical Meta-Analysis: A Simulation Study Comparing Classical Random Effects And Fully Bayesian Methods, Nancy R. Andiloro

Dissertations, Theses, and Capstone Projects

Meta-analytic data have a natural hierarchical structure to them, where individuals are nested within studies, and have both within-and between-study variation to model. A random-effects hierarchical linear model is useful to conduct a meta-analysis because it allows one to appropriately parse out the two components of variation that exist within and across studies to determine an observed effect. Empirical Bayes estimation considers the reliability of variance estimates; when the reliability of the effect size estimate for a study is high, substantial weight is placed on that estimate. However, problems with estimation arise when the number of studies and their sample …

Iterative Design Of A Simulation-Based Module For Teaching Evolution By Natural Selection, Jody Clarke-Midura, Denise S. Pope, Susan Maruca, Joel K. Abraham, Eli Meir

Instructional Technology and Learning Sciences Faculty Publications

Background: This research builds on a previous study that looked at the effectiveness of a simulation-based module for teaching students about the process of evolution by natural selection. While the previous study showed that the module was successful in teaching how natural selection works, the research uncovered some weaknesses in the design. In this paper, we used design-based research to investigate how design changes to the module affected not only students’ understanding of the concepts but also their usage of misconceptions in the assessments. We present results from two studies. In study 1, we looked at gains in understanding …

A Study Of Flight Simulation Training Time, Aircraft Training Time, And Pilot Competence As Measured By The Naval Standard Score, Aaron D. Judy

Doctor of Education (Ed.D)

The purpose of the study was to investigate the relationships between US Navy T-45C flight simulation training time, actual aircraft training time, and intermediate and advanced jet pilot competence as measured by the Naval Standard Score (NSS). Examining the relationships between US Navy T-45C flight simulation time and actual aircraft flight time may provide further information on flight simulation training versus actual aircraft training to aviation authorities, flight instructors, the military aviation community, the commercial aviation community, and academia. The study was non-experimental, correlational, causal-comparative with an emphasis upon the establishment of mathematic and predictive relationships using archival data from …

Criteria To Confirm Models That Simulate Deforestation And Carbon Disturbance, Robert Gilmore Pontius

Geography

The Verified Carbon Standard (VCS) recommends the Figure of Merit (FOM) as a possible metric to confirm models that simulate deforestation baselines for Reducing Emissions from Deforestation and forest Degradation (REDD). The FOM ranges from 0% to 100%, where larger FOMs indicate more-accurate simulations. VCS requires that simulation models achieve a FOM greater than or equal to the percentage deforestation during the calibration period. This article analyses FOM's mathematical properties and illustrates FOM's empirical behavior by comparing various models that simulate deforestation and the resulting carbon disturbance in Bolivia during 2010-2014. The Total Operating Characteristic frames FOM's mathematical properties as …

Two Decades Of Advancement In Process Simulation Testing Of Ballast Strength, Deformation, And Degradation, Buddhima Indraratna, Ngoc Trung Ngo, Sanjay Nimbalkar, Cholachat Rujikiatkamjorn

Faculty of Engineering and Information Sciences - Papers: Part B

This paper describes salient features of a set of large-scale ballast testing equipment developed at the University of Wollongong, Australia, and how the test results and research outcomes have contributed to transforming tracks in the Australian heavy haul and commuter networks, particularly with regards to the strength, deformation, and degradation of ballast. Ideally, ballast assemblies should be tested in prototype scale under actual loading conditions. This is because a reduction in particle sizes for testing in smaller equipment can reduce the internal angle of friction (shearing resistance) of the granular assembly in a macro sense, and the angularity of the …

Determining Cutoffs For The Psychometric Synonym Analysis To Detect Ier, Tyler Barnes

Browse all Theses and Dissertations

The validity of individual responses is required for valid inferences drawn from data. Insufficient Effort Responding (IER; Huang, Curran, Keeney, Poposki, & DeShon, 2012) is one possible threat to individual response validity. There are many methods to detect IER, but the Psychometric Synonyms Index, despite its practical utility, is understudied. The purpose of this study is to provide recommendations for its use that are empirically grounded. Using a simulation, I found that the strength of the within-pair correlations used for inclusion into the index, the number of pairs, the type of random responding, the correlation between the pairs, the skewness …

Evaluating And Reducing The Effects Of Misclassification In A Sequential Multiple Assignment Randomized Trial (Smart), Jun He

Theses and Dissertations

SMART designs tailor individual treatment by re-randomizing patients to subsequent therapies based on their response to initial treatment. However, the classification of patients being responders/non-responders could be inaccurate and thus lead to inappropriate treatment assignment. In a two-step SMART design, by assuming equal randomization, and equal variances of misclassified patients and correctly classified patients, we evaluated misclassification effects on mean, variance, and type I error/ power of single sequential treatment outcome (SST), dynamic treatment outcome (DTRs), and overall outcome. The results showed that misclassification could introduce bias to estimates of treatment effect in all types of outcome. Though the magnitude …
