Evaluating The Validity And Reliability Of Textile And Paper Fracture Characteristics In Forensic Comparative Analysis, Zachary Bailey Andrews

Graduate Theses, Dissertations, and Problem Reports (ETD)

In a comparative forensic analysis, an examiner can report that a physical fit exists between two torn or separated items when they realign in a manner unlikely to be replicated. Due to the common belief that it is unlikely that two unrelated fractured objects would match with distinctive characteristics, a physical fit represents the highest degree of association between two items. Nonetheless, despite the probative value that this evidence could have to a trier of fact, few studies have demonstrated such assumptions' scientific validity and reliability. Moreover, there is a lack of consensus-based standard protocols for physical fit comparisons, making …

Incidence Of Cancer, Depression, And Economic Burden Of Prescription Nsaids Among Older Adults With Osteoarthritis: Statistical And Machine Learning Approaches, Nazneen Fatima Mohammed Umer Shaikh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding the role of chronic inflammation among older adults is critical because of its implications on chronic inflammatory conditions as well as its interaction with anti-inflammatory medications. Osteoarthritis (OA) is a heterogeneous multi-faceted joint disease with multi-tissue involvement of varying severity, and increasing evidence demonstrates a key role of chronic inflammation in its pathogenesis. Approximately 30 million adults in the United States have OA, and it is reported that a large proportion (43%) of them are older than 65 years. OA is typically treated using non-steroidal anti-inflammatory drugs (NSAIDs) for minimizing pain and reducing inflammation. NSAIDs have consistently shown clinically …

Face Recognition With Attention Mechanisms, Qiangchang Wang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Face recognition has been widely used in people’s daily lives due to its contactless process and high accuracy. Existing works can be divided into two categories: global and local approaches. The mainstream global approaches usually extract features on whole faces. However, global faces tend to suffer from dramatic appearance changes under the scenarios of large pose variations, heavy occlusions, and so on. On the other hand, since some local patches may remain similar, they can play an important role in such scenarios. Existing local approaches mainly rely on cropping local patches around facial landmarks and then extracting corresponding local representations. …

Synthetic Methods For Improved Scope And Efficiency Of Copper-Catalyzed Regioselective Alkene Boracarboxylation, Steven William Knowlden

Graduate Theses, Dissertations, and Problem Reports (ETD)

The synthesis of carboxylic acids is important to the chemistry community, owing to the broad applicability of these compounds as fine chemicals and pharmaceuticals. Method development over the last decade has focused on the preparation of carboxylic acids through transition metal catalysis utilizing CO₂ as a C1 synthon. Copper-catalyzed heteroelement(bora and sila)-carboxylation protocols provide functional group rich carboxylic acid products, yet remain underdeveloped and thus underutilized. Consequently, catalytic reductive difunctionalization methodologies in which CO₂ and B(pin) (pin = pinacolate: 2,3-dimethyl-2,3-butanediolate) are installed across the double bond of a vinyl arene were recently developed. These boracarboxylation protocols provided novel, …

Gun Culture 3.0, Andrew Phillip Stover

Graduate Theses, Dissertations, and Problem Reports (ETD)

There exist a criminology of firearms and an epidemiology of firearms use, but little in the way of a sociology of U.S. firearm ownership. Most social science study of firearms concerns illicit gun use and the harm that use produces. Compared to this body of work, little has been done to explore the culture of legal gun ownership. A few social scientists have attempted to change this by contributing their own interpretations of what a sociology of U.S. gun ownership might look like. Professor David Yamane, in doing just this, has posited a cultural model of contemporary gun ownership he …

“I Lost Everything I Owned… Now I’M Growing That Back”: Narratives Of Redemption After Meth Immersed Lives, Danielle M. Stoneberg

Graduate Theses, Dissertations, and Problem Reports (ETD)

There is a lack of knowledge on how the process of desisting (i.e., maintaining abstinence) works for those leaving immersed drug lifestyles, leaving a need for a better understanding of the role and impact of identity in drug desistance. Through secondary analysis of interview data from a sample of 33 former methamphetamine manufacturers, this study examines the applicability of Maruna’s (2001) redemption narrative framework and identifies other aspects featured in their narratives that signaled identity change.

Human Welfare & Emergencies: Education, Natality, And Violence, Erika Antolin Davies

Graduate Theses, Dissertations, and Problem Reports (ETD)

I identify changes in human action during emergencies such as heavy precipitation and shelter-in-place orders. In two chapters I explore the effects of precipitation on educational attainment and birth rates as residential broadband access increases. In my third chapter I identify the movement of pets in and out of the home as a trigger for domestic violence during the COVID-19 lockdown. I estimate difference-in-difference regressions with panel data, coming to three conclusions. First: educational attainment in Appalachia is stunted by precipitation, as students have difficulty getting to school in bad weather. As this historically under-educated region of the US gains …

Utilizing The K18-Hace2 Mouse Model To Develop Protective Covid-19 Vaccines, Ting Y. Wong

Graduate Theses, Dissertations, and Problem Reports (ETD)

The ongoing Coronavirus Disease 2019 (COVID-19) pandemic is caused by the respiratory virus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Similar to other respiratory viruses, SARS-CoV-2 is transmitted through inhalation of respiratory droplets and aerosols from infected individuals. Once inhaled, SARS-CoV-2 utilizes the receptor binding domain (RBD) on the spike protein to bind to human Angiotensin Converting Enzyme 2 (hACE2) receptor to gain entrance into host cells to begin viral replication. SARS-CoV-2 infection can result in mild to severe cases of COVID-19 ranging from asymptomatic infections, cold or flu like symptoms to respiratory failure. The onset of the pandemic in …

Examining The Pulmonary Response To Repeated Vishniacozyma Victoriae Exposure And Its Association With Allergic Airway Disease, Rachael Erin Rush

Graduate Theses, Dissertations, and Problem Reports (ETD)

Allergic airway diseases such as asthma continue to increase in incidence in industrialized nations like the United States. These diseases are complex inflammatory processes involving numerous cells and mediators and are strongly influenced by fungal exposures. Recent developments in fungal detection methods have highlighted the contribution of Basidiomycota yeast species in indoor environments such as Vishniacozyma (syn. Cryptococcus) victoriae. However, despite the high levels of this yeast detected in indoor environments, very little is known about it or its role in respiratory morbidity. V. victoriae is phylogenetically similar to pathogenic Cryptococcus neoformans but lacks a capsule and is …

Small Mammal Communities Of Restored And Natural Wetlands In West Virginia, Krista Noe

Graduate Theses, Dissertations, and Problem Reports (ETD)

Wetland restoration is commonly practiced as part of conservation programs or wetland mitigation, which attempts to offset human-created losses of natural wetlands. However, because of the intrinsic and human-derived value of wetlands, it is critical to determine whether these wetlands truly act similarly to natural wetlands. One role of wetlands is to provide habitat for a diverse array of wildlife species. Small mammals are often overlooked taxa in wetland restoration efforts. However, they are essential to the wetland system because they influence vegetation and are prey for higher trophic level wildlife. I discuss considerations of restored wetlands, wildlife responses to …

Freeze! The Impact Of A Guided Imagery Intervention On Looming Vulnerability And Subclinical Contamination-Ocd Symptoms, Amber Lynn Billingsley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Looming vulnerability (LV) refers to the tendency to appraise and perceive potential threats as dynamic and increasing in risk. Research suggests that contamination-fearful individuals may have an increased tendency to interpret contamination as growing or spreading (i.e., “looming”), which may hinder habituation to contamination and play a role in the maintenance of contamination-OCD symptoms. Studies have shown that engaging in imagery in which one mentally freezes contamination in place decreases state levels of fear, though little is known about its longer-term effects (e.g., after one week). The present study aimed to experimentally manipulate LV using freeze imagery in a subclinical …

Embodied Energy Geographies: An Exploration Of Fracked Landscapes In The Ohio River Valley, Rachael L. Hood

Graduate Theses, Dissertations, and Problem Reports (ETD)

Methane gas production has boomed across the United States as a result of the development of fracking technology and its associated infrastructures, including pipelines. This production has provoked resistance over a litany of environmental and social concerns at both global and local scales. These concerns are compounded by a history of extractive economies and degradation in the Marcellus shale region of Appalachia and the Ohio River Valley. To date, there has been limited research at the intersection of extractive industry and emotional geography, especially around pipelines. This research draws on feminist, emotional, and energy geographies and uses semi-structured interviews and …

Evaluating Dro With Asymmetrical Magnitude Of Reinforcement, Lindsey M. Hronek

Graduate Theses, Dissertations, and Problem Reports (ETD)

Differential reinforcement of other behavior (DRO) is a reinforcement schedule used in behavior analytic procedures aimed at decreasing various forms of challenging behavior. DRO commonly includes a reinforcement component and an extinction component; a reinforcer is delivered on an interval-based schedule dependent on the omission of a target behavior and the reinforcer is withheld following the occurrence of the target behavior (i.e., extinction). Although interventions using DRO can be effective for challenging behavior, procedures that include extinction can at times be impractical or lead to undesirable side effects. A DRO schedule can be implemented without extinction, but previous research has …

Behaviors, Contextual Influences, And Consequences: Relationships That Affect Student Decision-Making Of Academic Misconduct In College, Justine A L Burnett

Graduate Theses, Dissertations, and Problem Reports (ETD)

Academic misconduct on college campuses is not a new challenge for higher education institutions but an old problem that has changed considerably. Student demonstrations of academic misconduct behaviors have evolved, making it difficult for institutions to consistently keep well-informed on how students cheat to effectively respond to violations of academic integrity policies. This study investigates the relationships between misbehaviors, their associated consequences, and influences to prevent, respond to, and reduce academic misconduct at a large research-intensive university.

This quantitative study uses institutional academic misconduct reports between 2017 and 2020 and student surveys to examine significant relationships in the decision-making process …

Athlete Attachment Style With Coaches As A Predictor Of Athlete Disordered Eating And Body Image Anxiety, Taylor Allen

Graduate Theses, Dissertations, and Problem Reports (ETD)

The coach-athlete relationship has been established as an important and significant relationship within athletes’ lives (Davis & Jowett, 2010; Jowett, 2008). There is also literature that demonstrates the impact of the sport culture environment and the quality of the coach-athlete relationship on disordered eating and body image anxiety in athletes (Galli et al., 2011; Petrie & Greenleaf, 2012; Reel et al., 2010; Shanmugam et al., 2013). However, much of the current literature does not examine this significant coach-athlete relationship from an attachment framework. Current literature supports the significance of the coach-athlete relationship and more recent research supports viewing coaches as …

Reinforcement Learning For Process Control: Applications To Energy Systems, Elijah Ballard Hedrick

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reinforcement learning (RL) is a machine learning method that has recently seen significant research activity owing to its successes in the areas of robotics and gameplaying (Silver et al., 2017). However, significant challenges exist in the extension of these control methods to process control problems, where state and input signals are nearly always continuous and more stringent performance guarantees are required. The goal of this work is to explore ways that modern RL algorithms can be adapted to handle process control problems; avenues for this work include using RL with existing controllers such as model predictive control (MPC) and adapting …

A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot

Graduate Theses, Dissertations, and Problem Reports (ETD)

Preclinical behavioral neuroscience often uses choice paradigms to capture psychiatric symptoms. In particular, the subfield of operant research produces nested datasets with many discrete choices in a session. The standard analytic practice is to aggregate choice into a continuous variable and analyze using ANOVA or linear regression. However, choice data often have multiple interdependent outcomes of interest, violating an assumption of general linear models. The aim of the current study was to quantify the accuracy of linear mixed-effects regression (LMER) for analyzing data from a 4-choice operant task called the Rodent Gambling Task (RGT), which measures decision-making in the context …

Investigating The Mitochondrial Protein Mitoneet In C. Elegans Models Of Aging And Alzheimer's Disease, Jacob Ryan Boos

Graduate Theses, Dissertations, and Problem Reports (ETD)

Oxidative stress is an imbalance between reactive oxygen species production and elimination, favoring the former. Reactive oxygen species serve as important signaling molecules for physiological homeostasis. However, when produced in excess, these once important signaling molecules become detrimental, disrupting cellular functions, and ultimately leading to cell death. In aging, reactive oxygen species production is increased, accompanied with reductions in oxidative stress resistance, increasing the risk for developing age-related diseases including cardiovascular disease, cancer, stroke, and neurodegenerative diseases. The outer mitochondrial membrane iron-sulfur cluster containing protein mitoNEET (CISD1; gene CISD1) has shown to be a mediator of mitochondrial function and …
