Applying Artificial Intelligence To Medical Data, Shaikh Shiam Rahman

College of Graduate Studies: Theses & Dissertations

Machine learning, data mining, and deep learning has become the methodology of choice for analyzing medical data and images. In this study, we implemented three different machine learning techniques to medical data and image analysis. Our first study was to implement different log base entropy for a decision tree algorithm. Our results suggested that using a higher log base for the dataset with mostly categorical attributes with three or more categories for each attribute can obtain a higher accuracy. For the second study, we analyzed mental health data tuning the parameters of the decision tree (splitting method, depth and entropy). …

We propose an ANN-based model to analyze a patient's electrocardiogram (ECG) data and produce accurate diagnostics regarding possible heart diseases …

Schools For Profit Or Schools For Education? A Christian School Principal’S Perspectives, Michael A. Crosby

College of Graduate Studies: Theses & Dissertations

This dissertation is a series of speculative essays (Schubert, 1991) that address the forces of neoliberalism on schools today– both public and private. While there have been studies on the detrimental effects of high-stakes testing on public schools (e.g., Au, 2015; Giroux, 2014; Wacquant, 2000) as well as the associated harmful effects of school to prison pipeline (e.g., Saltman, 2016; Taubman, 2009), there remains little research associated with the damaging impacts of neoliberalism on Christian schools. Building upon the theoretical framework of critical pedagogy (e.g., Friere, 1970; Kincheloe, 2008; McLaren, 2015), I undertake a critical examination of neoliberalism’s calculated efforts …

This research presents a novel algorithm for robust and accurate contour estimation of opposing vehicles. The presented …

Physiological Response Of Elasmobrachs During Propofol Immersion, Matthew Levendosky

College of Graduate Studies: Theses & Dissertations

Sensory experiments require anesthesia so the animal is immobilized, however fish anesthetics have shown to depress sensory responses. Newer anesthetics may offer similar anesthetic relief, but differ in means of action so sensory responses may be unaffected. Propofol has been used intravenously on small elasmobranchs but may provide prolonged effects if used as an immersion anesthetic. Objectives of this study were 1. Determine appropriate concentration of anesthetic to minimize induction and recovery for animals anesthetized at a surgical plane of anesthesia and 2. Measure physiological response of the pupil to light stimuli during anesthetic immersion. To address these objectives, I …

Athletic trainers are responsible for providing and coordinating healthcare for student-athletes when it is needed. In order to provide high-quality care, it is important that they understand the unique values and experiences of each individual athlete (Unruh, 1998).

Objective: The purpose of this study was to examine how cultural factors and past experience impact health behavior in …

Place Vulnerability Assessment In Coastal Georgia, Usa, Bless Dupeh

College of Graduate Studies: Theses & Dissertations

The complexity of vulnerability to natural hazards requires a thorough assessment of both physical and social factors. Physical vulnerability explains the occupancy within hazardous zones and social vulnerability determines how a community can cope, respond to, and recover from disasters. The determination of both physical and social vulnerability helps find the overall vulnerability of a place and this in turn helps with hazard mitigation. This study assesses the overall place vulnerability by examining both physical and social vulnerability in six Coastal Georgia counties. This study also uses Principal Component Analysis (PCA) to generate a social vulnerability index. To obtain the …

Compliance With Police: Does The Interaction Of Race/Ethnicity And Sex Matter?, Claire L. Halliburton

College of Graduate Studies: Theses & Dissertations

The often controversial nature of police use of force continues to cast law enforcement in a negative light, increasing an already historically tense relationship between law enforcement and the communities they serve. As cases of police brutality continue to surface, the legitimacy of police personnel continues to decrease, but community member behaviors toward officers are infrequently explored. Questions about the influence of situational, legal, and officer/community member characteristics arise in an attempt to further explore how these factors influence community member compliance. Thus, this study aims to understand police-community relations more clearly, focusing on the effects, if any, that the …

Professionalizing Emergency Medical Services (Ems): Still At The Crossroads, B. Jeanine Newton-Riner

College of Graduate Studies: Theses & Dissertations

In this work, I examine the failure of Emergency Medical Services (EMS) to professionalize over the course of its existence as an occupation. I consider how popular culture has contributed to a conflicted identity between what the public sees and how EMS providers view themselves. I believe that EMS has been restrained from professionalization due to oppression by physicians in a manner consistent with how two other allied health professions, pharmacy, and physical therapy, once were. I explore the professionalization of these two occupations to identify similarities and differences that may provide insight into next steps needed by EMS providers …

Exploring Health Attitudes And Academic-Community Engagement Of Faculty At Accredited Schools And Colleges Of Public Health In The U.S., Maria I. Olivas

College of Graduate Studies: Theses & Dissertations

Academic-community collaborations (ACCs) help communities identify health problems/priorities, improve social determinants of health, engage in the design and implementation of projects, and provide students with opportunities to learn outside the classrooms. Extensive research has focused on exploring challenges, facilitators, lessons learned, and best practices for conducting ACCs and engaging in partnerships. Nevertheless, no studies have evaluated the intra-organizational health attitudes of faculty in schools and colleges of public health and their impact on academic-community engagement. Organizational health attitudes matter because these are basic underlying assumptions that can shape the culture of academic-community engagement at schools and colleges of public health. …

Understanding The Relationships Between Combat-Related Ptsd Symptoms And Drinking Motives On Military Parental Satisfaction, Melissa C. Hinely

College of Graduate Studies: Theses & Dissertations

As of 2017, over 1.3 million Americans are enlisted in the U.S. Armed Forces (Department of Defense, 2017). Military personnel, particularly those exposed to combat, are significantly more likely to experience Posttraumatic Stress Disorder (PTSD; Xue et al., 2015). Furthermore, persons with PTSD are more likely to misuse alcohol, particularly when motivated to drink as a means to cope with negative emotions related to their PTSD symptoms (Simpson et al., 2014). Both PTSD and alcohol misuse have been found to contribute negatively to parental satisfaction and distress (Chesmore et al., 2018; McGraw et al., 2018). Veterans/service members who were parents …

Multiple Imputation Using Influential Exponential Tilting In Case Of Non-Ignorable Missing Data, Kavita Gohil

College of Graduate Studies: Theses & Dissertations

Modern research strategies rely predominantly on three steps, data collection, data analysis, and inference. In research, if the data is not collected as designed, researchers may face challenges of having incomplete data, especially when it is non-ignorable. These situations affect the subsequent steps of evaluation and make them difficult to perform. Inference with incomplete data is a challenging task in data analysis and clinical trials when missing data related to the condition under the study. Moreover, results obtained from incomplete data are prone to biases. Parameter estimation with non-ignorable missing data is even more challenging to handle and extract useful …

The Strong Families Program: Differential Impacts Of Resilience And Parent Management Training, Katie Slusher

College of Graduate Studies: Theses & Dissertations

Childhood behavior problems are pervasive with 50% of non-referred families citing noncompliance and behavior problems as an issue (Achenbach & Edelbrock, 1981). Many behavioral parent trainings (BPTs) treat these behaviors at an early age. Recently, adaptions to BPTs include group formats increasing accessibility and decreasing cost, especially for rural families with limited resources (Niec, Barnett, Prewett, & Stanley Chatham, 2016). Beyond BPTs, Alvord, Zucker, and Johnson Grados (2011) developed the Resilience Builder Program to enhance children’s social, emotional, and behavioral skills through a cognitive behavioral framework. The Resilience Builder Program improves anxious and depressive symptoms and reduces behavior problems in …

The Combined Effects Of Chemicals Used In Textile Processing On Plankton Communities., Diana Wilson

Honors College Theses

Industrial discharge, such as textile effluent, is a major source of chemical mixtures to surface waters. The effects of these mixtures on interacting aquatic organisms can be difficult to predict. We hypothesized that individual chemical effects on phytoplankton and a zooplankton grazer are altered by the presence of other chemicals in mixtures. Microcosms containing a phytoplankton food source (Chlorella sp.) and a zooplankton grazer (Daphnia magna) were exposed to THPC, ammonium, and hydrogen peroxide in a fully crossed design in a greenhouse for one week. Phytoplankton abundance was quantified and zooplankton response was measured as mortality and …
