Hearing Aid Acclimatization In The Context Of Central Gain Mechanisms, Peter J. Hutchison Nov 2020

Hearing Aid Acclimatization In The Context Of Central Gain Mechanisms, Peter J. Hutchison

Graduate Theses and Dissertations

The primary goals of this dissertation were to 1) identify markers of central gain in the auditory system following short-term acoustic attenuation via earplugging and acoustic enhancement via sound generators, and 2) determine if acoustic enhancement is effective in modulating central gain in older adults with age-related hearing loss, and if so, to what extent. Additionally, a further goal of this dissertation was to explore the possibility that central gain is related hearing aid acclimatization. The results described in Chapter 2 are further evidence that altering acoustic input to the peripheral auditory system modulates central auditory plasticity and is evident ...


Evaluation Of Aging And Genetic Mutation Variants On Tauopathy, Amber M. Tetlow Nov 2020

Evaluation Of Aging And Genetic Mutation Variants On Tauopathy, Amber M. Tetlow

Graduate Theses and Dissertations

Alzheimer’s disease (AD) is characterized by amyloid β plaques and neurofibrillary tau tangles (NFTs). While research has demonstrated amyloid pathology occurs prior to tau pathology, or tauopathy, tau has proven to be more toxic. Tauopathy is associated with cognitive declines and neurodegeneration. These findings have highlighted the importance of further understanding tauopathy. In the progression of tauopathy, there is an observable immune response that can be measured by glial cells such as microglia. Activated microglia are known to exacerbate tauopathy rather than reducing the pathology. Research has indicated that with increased age there is an increased risk for AD-related ...

Physicians across the United States are burdened with the pressure of accurate coding while trying to maintain quality patient care. Despite the economic importance of coding accuracy, investigators have not reached consensus on the factors that contribute to coding errors. This study fills this gap by investigating physician characteristics that explain the variation in physician coding accuracy, specifically evaluation and management upcoding and downcoding errors. An electronic survey was distributed to 325 physicians that measured physicians’ attitudes towards risk and coding self-efficacy. Regression analysis found physicians with low self-efficacy had more conservative coding behaviors, resulting in higher incidences of downcoding ...


On The Importance Of Context: Examining The Applicability Of Infertility Insurance Mandates In The United States Using A Mixed-Methods Study Design, Nathanael B. Stanley Oct 2020

On The Importance Of Context: Examining The Applicability Of Infertility Insurance Mandates In The United States Using A Mixed-Methods Study Design, Nathanael B. Stanley

Graduate Theses and Dissertations

Accessibility of infertility services is disproportionately experienced in the United States. Although there exist state-based health insurance mandates for infertility services, these mandates contain language that disqualify people from using them. In order to better understand why these mandates are not able to reduce the financial burden and bridge the income disparity for using infertility services, the purpose of this study is to add context to the applicability of these insurance mandates through qualitative and quantitative inquiry. Using the Glass and McAtee model of risk regulators as an operational paradigm, this research explores the role of environmental context, or “place ...


Effects Of The 340b Drug Pricing Program On Hospitals’ Prescribing Behavior, Patient Mix, And Quality Of Care, Yilu Dong Jul 2020

Effects Of The 340b Drug Pricing Program On Hospitals’ Prescribing Behavior, Patient Mix, And Quality Of Care, Yilu Dong

Graduate Theses and Dissertations

In 1992, Congress created the 340B Drug Pricing Program that requires drug manufacturers to provide outpatient drugs to participating hospitals with substantial discounts. Although the intent of the program is to allow covered entities to increase access to care for more vulnerable patients, hospitals are not required by law to pass on the discounts. Therefore, a concern is that hospitals might over-prescribe. This dissertation includes three chapters to study the effects of the 340B program on hospitals’ behavior changes:

Chapter 1 uses state aggregate hospital service spending data from the Centers for Medicare and Medicaid Services (CMS) to study the ...

Temporal Discounting And The Assessment And Treatment Of Academic Procrastination, Anthony Concepcion Jul 2020

Temporal Discounting And The Assessment And Treatment Of Academic Procrastination, Anthony Concepcion

Graduate Theses and Dissertations

Many individuals engage in procrastination at some point in their lifetime. Although procrastination is usually not detrimental, for college students, academic procrastination is correlated with adverse health effects (e.g., anxiety, depression, sleep hygiene) and poor academic performance (Akinsola, et al., 2007; Ferrari, et al., 1995). Furthermore, the prevalence of academic procrastination is high with reports of up to 95% of college students engaging in detrimental amounts of procrastination (Hussain & Sultan, 2010). Notably, students enrolled in online courses are likely to be at greater risk to experience adverse consequences associated with procrastination (Elvers, et al, 2003). Previous studies have focused ...


Evaluating Public Posting, Goal Setting, And Rewards To Increase Physical Activity In Children, Bryon G. Miller Jul 2020

Active Deep Learning Method To Automate Unbiased Stereology Cell Counting, Saeed Alahmari Jun 2020

Active Deep Learning Method To Automate Unbiased Stereology Cell Counting, Saeed Alahmari

Graduate Theses and Dissertations

Cell quantification in histopathology images plays a significant role in understanding and diagnosing diseases such as cancer and Alzheimers. The gold-standard for quantifying cells in tissue sections is the unbiased stereology approach. Unfortunately, in unbiased stereology current practices rely on a well-trained human to manually count hundreds of cells in microscopy images. However, this human-based manual approach is time-consuming, labor-intensive, subject to human errors, recognition bias, fatigue, variable training, poor reproducibility, and inter-observer error. Thus, the lack of high-throughput technology for automating unbiased stereology analyses remains a major obstacle to further progress in a wide range of neuroscience and cancer ...

Evaluating Small-Scale Simulation For Teaching Abduction Prevention Skills, Jessica E. Ritzmann

Graduate Theses and Dissertations

Approximately 1,600 attempted kidnappings occurred within 2018 (National Center for Missing & Exploited Children, 2019). In a 2016 report by Wolak, Finkelhor, and Sedlak, of the 105 stereotypical kidnappings that occurred in 2011, many resulted in sexual assault, the children are never found, or death. These dangerous circumstances warrant a method of teaching safety skills to children to avoid abduction. Research has shown that small-scale simulation is effective for teaching firearm safety to 3- to 5-year-olds children (Maxfield, Miltenberger, & Novotny, 2019). This research has not been applied to abduction prevention safety. The current study aimed to address this research gap ...

Family Response To A Diagnosis Of Serious Mental Illness In Teens And Young Adults: A Multi-Voiced Narrative Analysis, Douglas J. Engelman Jun 2020

Family Response To A Diagnosis Of Serious Mental Illness In Teens And Young Adults: A Multi-Voiced Narrative Analysis, Douglas J. Engelman

Graduate Theses and Dissertations

Narratives are stories, stories persuade, persuasion is necessary to develop social problem consciousness, and social problem consciousness is a necessary element of mobilization toward social change. Thus, narratives are intrinsic to social change, both in the form of policy and legislation, and as evidenced by transformations in culture and consciousness. In this dissertation I analyze narratives about mental illness in families because they reflect what we think of as common, everyday understandings about these experiences. Through these analyses, I hope to learn how individuals and families understand the diagnosis of mental illness through stories they tell about how they cope ...

Mass Spectrometry Discovery-Based Proteomics To Examine Anti-Aging Effects Of The Nutraceutical Nt-020 In Rat Serum, Samantha M. Portis

Graduate Theses and Dissertations

Aging is a complex physiological process that leads to the deterioration of all cells and tissues throughout the body. Aging is a major risk factor for the onset of many degenerative diseases in both the central nervous system (CNS) and the periphery, but even nonpathological aging (“normal” aging) is associated with chronic inflammation, oxidative stress, and decreased stem cell proliferation and regenerative capacity. This decreased regenerative capacity in stem cell niches is thought to be a key component underlying the aging process and many disease states associated with aging.

While the exact biological mechanisms underlying impaired stem cell proliferation and ...

Essays On The Disposition Effect, Matthew Henriksson Mar 2020

Essays On The Disposition Effect, Matthew Henriksson

Graduate Theses and Dissertations

This dissertation contains two essays that shed new light on the disposition effect – that is, the tendency for investors to be especially eager to realize gains over losses. The first essay combines county-level natural disaster data with individual investor transactions to document an increased disposition effect for investors impacted by a natural disaster. This effect is increasing in disaster severity and decreasing in the length of time following the event, suggesting that extreme natural disasters can significantly influence investor behavior, especially in the short term. These findings are not explained by liquidity needs, tax incentives, or informed trading. The effect ...
