Ireland V. United States: Agricultural And Environmental Sustainability Policies, Lauryn O'Grady

Accounting Undergraduate Honors Theses

The United States and Ireland have varying practices to achieve similar objectives in regard to environmental sustainability. While the European Union has maintained and updated a uniform policy throughout its existence--the Common Agricultural Policy--the United States instead created short-term solutions to a long-term problem. Not only does the United States tend to solve issues in the short-term, the policies between agricultural production and environmental sustainability are not necessarily aligned or remotely relative to the other. While the United States’ new Global Food Security Strategy implements parts of both agricultural and environmental sustainability, much of the history was not based off …

Fixed Assets Accounting: How It Can Impact Employees, Auditors & Shareholders, Zach Markey

Accounting Undergraduate Honors Theses

As a foundation for this thesis, I give an overview of fixed assets accounting by explaining its magnitude on the balance sheet and income statement in addition to the differences between financial and tax accounting for fixed assets. Next, I focus on three areas relating to fixed assets accounting that I find the most compelling for this thesis: capital expenditures, auditing and fraud. Each of these subtopics will share studies, procedures, and stories on how …

The Myth Of Perfection: Charting The Rhetoric Of Veteran Disability For A Course To Stability, Nicholas Rader

All Dissertations

This dissertation rhetorically analyzes discrimination in Western institutional discourses and documentation procedures, such as architectural texts and procedures, through a historiographic lens. An analytical methodology will be offered to show how discrimination of intersectional bodies is historically informed and reaffirmed by the manipulation of Western myths and mythos. Specifically, by mapping navigational mathematics and cartographic methods over rhetorical, architectural, and historiographic theory, it will be shown how the manipulation of Western myths establishes and reifies patriarchal discrimination that eventually fissions into eugenicist logics in nineteenth and twentieth century France, England, and the United States. In modernity, the practice of manipulating …

Modeling Antihypertensive Therapeutic Inertia And Intensification To Support Clinical Action Toward Hypertension Control, Benjamin Martin

All Dissertations

Background

Hypertension is the leading modifiable risk factor for cardiovascular disease and consequent mortality worldwide. In the U.S., more than half of hypertension cases remain uncontrolled, despite availability of effective pharmaceutical treatment options. Evidence suggests that therapeutic inertia, defined as clinician failure to initiate or increase therapy when treatment goals are unmet, is the most influential barrier to improving hypertension control. Substantial rates of therapeutic inertia have been reported in ambulatory primary care settings where hypertension is typically treated and managed. Understanding and overcoming the forces driving therapeutic inertia in hypertension management is a critical strategy to reach population health …

Hydrothermal Synthesis Of Frustrated Lanthanide Pyrochlores And Transition Metal Double Perovskites And Germanates, Matthew S. Powell

All Dissertations

Magnetically frustrated materials hold promise of unique behavior allowing for the novel study of quantum phenomena. Such materials are poised to become an integral foundation for technological advancement in the post-Silicon Age. Crystalline materials are given special focus where the rigid lattice allows more detailed study of these quantized effects and frustration behavior. As opposed to polycrystalline powders, large single crystals can be preferentially aligned enabling the study of anisotropic behavior. Two cubic structure types have garnered significant interest due to their 3-D tetrahedral arrangement of symmetry-related metal centers with the potential for magnetic frustration: pyrochlores and perovskites.

Accelerating The Derivation Of Optimal Powertrain Control Strategies Using Reinforcement Learning And Virtual Prototypes, Daniel Egan

All Dissertations

The push for improvements in fuel economy while reducing tailpipe emissions has resulted in significant increases in automotive powertrain complexity, subsequently increasing the resources, both time and money, needed to develop them. Powertrain performance is heavily influenced by the quality of their controller/calibration with modern powertrains reaching levels of complexity where using traditional design of experiment-based methodologies to develop them can take years. Recently, reinforcement learning (RL), a machine learning technique, has emerged as a method to rapidly create optimal controllers for systems of unlimited complexity directly which creates an opportunity to use RL to reduce the overall time and …

Comparison Of Covid-19 Diagnostic Testing Methodologies In The U.S., Joseph Blommel

All Dissertations

The onset of the COVID-19 pandemic brought about a world in which diagnostic testing for the virus that is responsible for COVID-19, SARS-CoV-2, became commonplace. Diagnostic testing was required for myriad reasons beyond simple diagnosis. We set out to compare SARS-CoV-2 testing methods, see if differences sensitivity correlated to increased positivity, and to evaluate self-collection methods.

In examining the Limit of Detection (LoD) of tests receiving FDA Emergency Use Authorization (EUA), our findings indicated that there were considerable differences in LoD. However, these differences in observed sensitivity were not correlated with the methodologic differences as reported in EUA documentation.

Reflections On Co-Creating Nature-Based Virtual Reality Experiences For Adults Living With Severe Copd, Olivia Mcanirlin

All Dissertations

This dissertation focused on studying the lived experience of working with and for people living with severe chronic obstructive pulmonary disease (COPD) to co-create a personalized nature-based virtual reality (VR) experience. People with severe COPD have issues with being able to breathe clearly and deeply, which then influences their ability to visit outdoor places. Outdoor places have been shown to have many positive effects on multi-dimensional health outcomes. Severe COPD can also make traveling to faraway destinations and even visiting nearby outdoor spaces difficult. Therefore, the purpose of this dissertation was to develop personalized nature-based VR experiences as an alternative …

The Role Of Attention Control In Automation Performance, Claire Textor

All Dissertations

Research in human-automation interaction has demonstrated that some individuals are more severely impacted by the negative effects of unreliable automation (i.e., exhibit lower performance) than others. A body of work has sought to explain this variability through individual differences, primarily investigating the role of working memory. However, not all studies have demonstrated a clear relationship between working memory capabilities and performance when using automation. Engle’s (2002) controlled attention theory of working memory posits that the relationship between working memory and other cognitive constructs such as fluid intelligence can be explained through a shared reliance on attention control. Studying the role …

Validating A Human Trafficking Screening Tool For Women Returning To Uganda From The Middle East, Jason Pope

All Dissertations

Human trafficking is a global issue. Denying its existence creates an atmosphere where it can thrive. Therefore, visibility is a key step in prevention. Human trafficking screening tools bring visibility to this hidden issue. Identifying individuals who have experienced human trafficking is essential for preventing it from happening in the future. Identifying survivors of trafficking allows them to be provided aftercare and opens the doors for prosecuting those who perpetrate harm against others.

This study validated a human trafficking screening tool and developed a standard for interpreting the results. This study aimed to develop a tool that could identify human …

The second chapter identifies and analyzes practices for assessing speech, …

Multiparametric Continuous And Mixed-Integer Nonlinear Optimization With Parameters In General Locations, Andrew Pangia

All Dissertations

Convex programming has been a research topic for a long time, both theoretically and algorithmically. Frequently, these programs lack complete data or contain rapidly shifting data. In response, we consider solving parametric programs, which allow for fast evaluation of the optimal solutions once the data is known. It has been established that, when the objective and constraint functions are convex in both variables and parameters, the optimal solutions can be estimated via linear interpolation. Many applications of parametric optimization violate the necessary convexity assumption. However, the linear interpolation is still useful; as such, we extend this interpolation to more general …

Beyond Just Money Transactions: Redesigning Digital Peer-To-Peer Payments For Social Connections, Lingyuan Li

All Dissertations

Financial activities, such as the exchange of money between individuals, have long been considered a crucial aspect of how people build and maintain their interpersonal relationships (i.e., a strong, deep, or close association/acquaintance between two or more people) with individuals they know because money is a sensitive social construct. In particular, over the past decade, how to conduct, manage, and experience money exchanges and processes between individuals has been dramatically transformed due to the increasing popularity of digital peer-to-peer (P2P) payment services (i.e., performing one to one online money transactions via a digital device). In this sense, digital P2P payments …

All Dissertations

Predicting the states of the surrounding traffic is one of the major problems in automated driving. Maneuvers such as lane change, merge, and exit management could pose challenges in the absence of intervehicular communication and can benefit from driver behavior prediction. Predicting the motion of surrounding vehicles and trajectory planning need to be computationally efficient for real-time implementation. This dissertation presents a decision process model for real-time automated lane change and speed management in highway and urban traffic. In lane change and merge maneuvers, it is important to know how neighboring vehicles will act in the imminent future. Human driver …

Developing A Cultural Management Approach To Bermudagrass Mite (Acari: Eriophyidae) Infestation, Matthew Brown

All Dissertations

Bermudagrass mite (Aceria cynodoniensis Sayed) (Acari: Eriophyidae) infestation stunts bermudagrass growth, leading to thinned turf and lower aesthetic and recreational value. Cultural management practices may impact bermudagrass mite infestation and turfgrass recovery from mite damage. Scalping or mowing shorter may physically remove mites, while drought stress may increase grass susceptibility to mites. Fertilizer application may promote mite infestation by improving plant nutrition. I conducted greenhouse, nursery, and field experiments to evaluate the impact of nitrogen fertility, irrigation rate, mowing height, and scalping on turf health and bermudagrass mite infestation in terms of the densities of witch’s brooms (i.e., stunted …

Development Of A Novel Predictive Model And Prosthetic System To Assess Dynamic Leg Length Based Gait Biomechanics In Lower Limb Prosthesis Users, Therese Parr

All Dissertations

Individuals with transfemoral amputation often rely on a prosthesis as a replacement for their missing extremity’s structure and function. Lower-limb prosthetic devices are developed with the goal of restoring biomechanical abilities and mitigating secondary health risks for users. However, biomechanical deficits for unilateral transfemoral prosthesis users are very common and are induced by both leg length discrepancy (LLD) and current prosthetic design shortcomings. Lack of push off power as well as difficulty shortening the leg for toe clearance can result in gait compensations that lead to asymmetric limb loading, increased muscle activity, and an increased incidence of falling due to …

Another finding was that more studies examining the races and ethnicity of these …

Acetate Metabolism In The Fungal Pathogen Cryptococcus Neoformans, Oly Ahmed

All Dissertations

Cryptococcus neoformans is an environmental basidiomycetous fungus with a worldwide distribution and a wide range of habitats. Inhalation of the desiccated yeasts or spores of C. neoformans often leads to opportunistic pulmonary infections in immunocompromised individuals, and in severe cases causes lethal meningitis following hematogenous dissemination. During infection, depending on the tissue and disease state, the invading fungi experience a range of nutrient microenvironments within the host body. As a result, rapid metabolic adaptations geared towards efficient utilization of carbon sources alternative to glucose become one of the prime determinants of survival and growth for the pathogen. Incidentally, cryptococcal infection …
