Revision And Biogeography Of The Tribulus Group (Orthoptera, Acrididae, Melanoplinae, Melanoplus) And Establishment Of The Rusticus Group With A Description Of Four New Species Of West Of Mississippi River, Usa, Jireh Mwamukonda

Theses and Dissertations

The genus Melanoplus represents one of the most diverse groups of acridid grasshoppers in North America, comprising over 430 described species within the subfamily Melanoplinae. Among its various species groups, the Tribulus group consists of flightless grasshoppers typically found in open woodlands and forest margins, primarily in the eastern United States. The Melanoplus tribulus group was first established by Blatchley (1920) as Obovatipennis Group. However, since species groups are informal taxonomic units not governed by nomenclatural rules, the group later became known as the Tribulus group. It currently includes 11 taxa. These brachypterous species occur from New Jersey south Florida …

Toward Approachable Reinforcement Learning: Using Dataflow Application And Large Language Models For Human-Understandable Policies, Joel Thomas Huber

Theses and Dissertations

Optimal decision-making under uncertainty is a challenge in everything from board games to business scenario planning. With visual programming systems, end-users can utilize reinforcement learning (RL) agents to identify an optimal policy in their own stochastic environments. However, while the RL agent can demonstrate that an optimal policy exists, RL polices tend to be opaque and difficult to interpret. This thesis investigates how Large Reasoning Models (LRMs) can generate human-understandable rules from RL policies. I compare multiple approaches and models, varying the format of the RL policy provided to the LRM as well as the prompting strategy. My results show …

An often-overlooked research gap is the applicability of research over time. The impact of updating the GNU Compiler Collection version was investigated for the SRTuner compiler optimization research. Versions 7 through 14 were tested using documented flags and recommended flag dependencies. Quality controls measured and enforced consistency across test runs and benchmarks. The performance of SRTuner was compared to a random control while the impact of enforcing flag dependencies was evaluated. The most influential flags were investigated by turning them off in isolation, but results were mixed. It was determined that enforcing flag dependencies resulted in improved performance, but the …

Responding To The Urban Canvas: Murals, Preservation, And Placemaking In Meridian, Ms, Katy Kemalyan

Theses and Dissertations

Public murals that depict elements of local culture and history are a creative placemaking tool increasingly used by preservationists invested in the revitalization of their historic districts. As this trend rises, it becomes necessary for preservationists to ask what should be painted, restored, or left alone? Research on public murals neglects Southern mid-sized towns, considerations of existing murals, and historic architecture used as substrates. Rectifying this omission and employing geographic surveys and stakeholder interviews, this study seeks to expand which genres of murals are considered for their creative placemaking value. Normally distinguished primarily by source in literature, community murals, ghost …

Advancing Equity In Adolescent Mental Health: A Literature Review And Telehealth Program Design For School-Based Access, Renatta Lindsey

Theses and Dissertations

Adolescents in the United States (U.S.) are experiencing a mental health crisis, with disproportionately high prevalence rates among marginalized youth. Approximately 1 in 5 adolescents are diagnosed with a mental, emotional, or behavioral condition (Panchal, 2024; Sappenfield et al., 2024). Yet, an estimated 40% (1.8 million) of adolescents aged 12-17 who experience a major depressive episode did not receive treatment (Substance Abuse and Mental Health Service Administration, 2024). This project examines existing barriers that hinder access to care for this population. While schools are the most common settings for adolescent mental health supports, more than half report difficulties with meeting …

Complex-Valued Structured Parameterized Learnable Filter Banks For Time-Frequency Domain Based Classification, Sabyasachi Biswas

Theses and Dissertations

Most conventional radar-based classification methods, including human activity recognition (HAR) and modulation recognition, rely on computationally intensive two-stage processes involving time-frequency (TF) transformations, such as the short-time Fourier transform (STFT), to generate micro-Doppler signature (��-Ds). These ��-Ds are then classified using deep neural network (DNN), a method introducing significant temporal latency and limiting real-time applicability. To overcome these limitations, this dissertation proposes a novel complex-valued Deep learning (DL) framework employing structured parameterized learnable filter (PLF) banks, enabling direct classification from raw radar data. The research first introduces high-resolution spectrogram network (HRSpecNet), a deep learning model designed to reconstruct high-resolution ��-Ds …

Spot spraying technology, which utilizes single nozzles or a limited number of nozzles to treat specific areas, is now available and gaining market penetration. However, its performance depends on carefully optimized application parameters to ensure consistent coverage and efficacy, thereby mitigating both under- and overdosing. To address concerns including reduced efficacy, resistance evolution, and environmental impacts, this work researches the effects of nozzle selection …

The Social In The Spiritual: Non-Theistic Spirituality In 12-Step Addiction Recovery, Steph Jacobs

Theses and Dissertations

To investigate whether Western-raised Narcotics Anonymous (NA) members engage in non-theistic spirituality and non-humanist modes of sociality with non-human beings, I conducted six qualitative interviews and a small-scale survey within a Vancouver NA community. The majority of participants practice non-theist spirituality, and three interviewees relate to non-humans in ways not accounted for by Western humanism. Findings suggest that connection and sociality are intrinsically woven into recovery and well-being. This research opens conversations about non-theistic spirituality in NA recovery, non-human sociality and healing, processes of ontological negotiation, and the entanglement of spirituality, sociality, and well-being. Through daily practices of exploration and …

A Case Study On Redesigning Classroom Activities And Assessments For Generation Z Students, Sushma Shrinivasan

Using piecewise multilevel modeling (MLM), the study evaluated changes in depressive symptoms, dyadic coping (DCI), and growth and empowerment measure (Emotional Empowerment Scale [EES-14] and 12 Scenarios [12S]) across waitlist and treatment phases. Five couples (10 individuals) participated in up to 17 waves, with staggered baseline and treatment lengths across dyads. Results indicated significant fixed effects of the 12S subscale for growth and empowerment during the treatment phase. There were no statistically significant fixed …

Power Resilience In Utah's Water Sector: A Survey Of Stakeholder Practices, Preferences And Potential, Tyler Christopher Peterson

Theses and Dissertations

Drinking water and wastewater services are vulnerable to disruptions because they rely heavily on the electric grid. As a result, power outages can lead to water outages, creating cascading failures that compromise sanitation, firefighting, healthcare, and daily routines. Although an important topic, there are little to no studies of water and wastewater power resilience at a geographic or state level. In this study we investigate the extent of existing backup power and renewable energy integration as well as the motivations and barriers around their power resilience. We collect our data through semi-structured interviews with staff at 19 urban and rural …

Evaluation Of Internal Field In Ppln And Studies On Qpm Shg Efficiency Factor, Prasath Rk Mr

Theses and Dissertations

Periodically Poled Lithium Niobate (PPLN) crystals have attracted interest in optoelectronics and nonlinear optics. The response to the applied electric field is determined by their larger electro-optic and nonlinear optical coefficients. An internal electric field exists in congruent PPLN crystals due to its defects. Its evaluation is important in controlling the electro-optical behavior. A simple nondestructive diffraction method is proposed to estimate the internal electric field present in the congruent lithium niobate crystal.

Due to the presence of an unrelaxed internal field, the as-poled sample acts as an index grating. When a light is incident on such a sample, it …

The Impact Of Social Factors On Vagally Mediated Parasympathetic Activity, Andrew Scot Proctor

Theses and Dissertations

Loneliness and social disconnection are recognized risk factors for morbidity and mortality, yet the psychophysiological pathways remain contested. This dissertation examines how social factors relate to vagally mediated parasympathetic activity indexed by heart rate variability (HRV) and tests whether conversational interventions with a human or a large-language-model (LLM)-based companion can acutely reduce loneliness and enhance connection. Across two university sites (BYU, UCSD), N=297 participants (18-27 years) were randomized to (a) a reciprocal self-disclosure conversation with a trained human confederate, (b) a parallel, vocalized LLM chatbot conversation, or (c) a non-social, vocal reading control. Resting HRV (RMSSD, SDNN, HF-HRV) was recorded …

Law As Performance: Sovereignty, Legal Indeterminacy, And The Chinese Private Security Industry, Alexandrya Pouliot

Theses and Dissertations

This thesis examines how the legal indeterminacy of international law facilitates state evasion of accountability through the use of private military and security companies (PMSCs) as proxies in extraterritorial operations. Focusing on China’s deployment of PSCs to safeguard Belt and Road Initiative (BRI) projects, it argues that ambiguities within the doctrines of attribution and responsibility under the Articles on the Responsibility of States for Internationally Wrongful Acts (ARSIWA) create a permissive legal environment that enables states to outsource coercive functions without incurring formal liability. Drawing upon Hobbesian Realist theory, Carl Schmitt’s concept of the sovereign exception, and insights from Critical …

Exploring The Potential Of Artificial Intelligence To Improve The Journal Peer Review Process, Eliza Fanny Bondah

Theses and Dissertations

Academic publishing depends on the peer review process to guarantee quality, scholarly rigor, and credibility, but the traditional peer review system receives mounting criticism because of its inefficient operations, biased judgments, and irregular standards. This study explores how artificial intelligence (AI) can improve journal peer review systems to solve a variety of issues, including reducing reviewer exhaustion, minimizing bias, improving consistency, and accelerating the review process. Current literature shows AI as a promising yet controversial solution, which may provide structured feedback with improved consistency and efficiency. Our study examined 52 human reviews together with 26 AI-generated reviews from EdTechnica--An Open …

Bayesian Alignment Prior To Connectionist Temporal Classification Loss, Lawry Sorenson

Theses and Dissertations

We propose revisions of Connectionist Temporal Classification (CTC) loss and forced alignment to support longer input sequences. CTC loss is normally used for training in speech and handwriting recognition tasks when the labels are not fully aligned with the data, while forced alignment is a downstream task that finds the optimal path for segmentation purposes. The current implementations consider all possible alignments between the input and label, which grows exponentially with the size of the input. We show that in cases when silence is removed and speaking rate is consistent, the true alignment is a mostly straight line across time …

Implementing Dataops: A Scalable Framework For Modern Data Warehousing, Dmytro Valiaiev

Theses and Dissertations

DataOps has been coined as a novel term that emerged as a synthesis of data management practices with software engineering concepts, such as DevOps and Agile, with the goal of improving data quality and governance in enterprises. The proliferation of scratch table use and transformation tools, such as dbt, has led to an exponential increase in the number of data models, which complicates standardization efforts and increases maintenance overhead. Although the market is saturated with various flavors of text-to-SQL engines that promote increased productivity and self-service use in organizations, there are limited tools available to optimize individual queries, enforce consistency, …

Toward Understanding Multi-Agent Decision Making In Complex Societies, Jonathan Skaggs

Theses and Dissertations

This dissertation investigates Multi Agent Decision Making (MADM) within Complex Societies (CS), systems of interdependent agents whose collective behaviors emerge from local interactions. Such emergent dynamics are nonlinear and difficult to predict, posing significant challenges towards understanding how individual decisions scale to societal outcomes. Existing approaches often fall short of capturing the combined attributes of CS, including asymmetry, decentralization, and adaptivity. To address this gap, we introduce new models and analyses of agent strategies that explain how cooperation and stability can arise in CS. Structured around three interrelated projects, this dissertation enhances our comprehension of MADM in CS. The research …

Towards Resilient Data Governance: An Industry Study On Practitioner Perspectives On The Current State Of Data Governance, Anthony Mazzarella Iii

Theses and Dissertations

Experts agree that data governance is crucial for managing data as an asset, yet in practice, it remains inconsistently defined, unevenly implemented, and poorly understood. Earlier industry studies offered valuable descriptive benchmarks of governance adoption and professional roles, but provided limited theoretical insight and little empirical evidence explaining how governance functions within organizations. Building on this foundation, the current research offers a more substantial and analytically rigorous contribution by transforming descriptive observations into empirical explanations. Through a collaborative academic–industry partnership, the study utilizes a global survey of 565 respondents (348 valid cases) to analyze governance structures, motivations, challenges, and the …
