Two Studies Exploring Signal-Environment Fit In Ai-Assisted Managerial Decision-Making Under Uncertainty, Oleksandr Kondrachuk

Graduate Studies Theses and Dissertations 2026

This dissertation examines how the fit between the characteristics of artificial intelligence systems and the uncertainty environment shapes managerial reliance on AI advice. Organizations increasingly deploy different AI systems, such as predictive and generative, to support management accounting decisions. However, the accounting literature has mainly treated AI as a single undifferentiated entity. This dissertation addresses this gap through two related studies. In the first study, drawing on signaling theory and ecological rationality, I develop a signal-environment fit framework proposing that the reliance on a certain AI system depends on the match between system characteristics (input, process, output) and uncertainty characteristics. …

The Impact Of Criminal Justice System Contact On Adolescents In The U.S.: Prescription Drug Misuse, Marijuana Use, Health Outcomes, And Demographic Characteristics, Fadime Gokce Karaaslan

Graduate Studies Theses and Dissertations 2026

Criminal justice system (CJS) contact remains a pervasive feature of social life in the United States, with both direct and indirect consequences for adolescents and their families. Although previous research has explored the consequences of direct CJS contact, less is known about how indirect or vicarious contact affects adolescents’ well-being and substance use. Drawing on data from the Future of Families and Child Wellbeing Study (FFCWS), this study investigates the association between parental incarceration and vicarious police stops, defined as police stops involving parents, siblings, friends, neighbors, or other social ties, and adolescent well-being. Findings indicate that CJS contact is …

Modeling And Mitigating Atmospheric Degradation In Computer Vision With Application In Renewable Energy Prediction, Sumit Laha

Graduate Studies Theses and Dissertations 2026

Weather-induced variability poses significant challenges to the reliability and performance of modern computational systems, particularly those relying on visual perception and environmental prediction. This dissertation focuses on enhancing computer vision and machine learning based predictive models that operate under varying atmospheric conditions. Two representative weather-impacted applications are investigated: image dehazing and solar photovoltaic (PV) power output forecasting. Image dehazing focuses on the restoration of clear, unobstructed visuals from hazy or foggy images, a task that is vital for various applications. On the other hand, photovoltaic (PV) power forecasting aims to predict future solar energy generation based on historical sky images …

Coordinated Whole-Body Dynamic Pressing And Reaction Inhibition — Impact Of High-Intensity Intermittent Exercise And Dehydration, Modesto A. Lebron

Graduate Studies Theses and Dissertations 2026

Dynamic whole-body pressing movements are an imperative aspect of various sport and occupational settings, requiring motor coordination to kinetically sequence from lower- to upper-extremities. Recently, exercises such as the jammer arm punch press (JPP) have increased in popularity, promoted as an exercise to improve strength and force transfer. While the JPP has observed increased practical utility, its use in research is limited potentially due to difficulties with quantifying exercise intensity. One method to quantify exercise intensity is the assessment of velocity, serving as the basis for velocity-based training. For optimization, this strategy requires an understanding of velocity ranges and their …

Bridging The Gap: How Sociodemographic Factors Shape Adults’ Decisions To Pursue Hearing Aids, Logan Lorié

Graduate Studies Theses and Dissertations 2026

Despite hearing aids becoming more accessible to adults with hearing loss, hearing aid uptake rates remain low, partly due to sociodemographic factors that influence an adults’ decision to pursue amplification. This study systematically reviewed research on how sociodemographic factors – to include age, gender, socioeconomic status, education level, race/ethnicity, and military status – contribute to the decision-making process. This review guided an analysis of these variables using the National Health and Nutrition Examination Survey (NHANES), a large public health database. To ensure enough hearing aid users were included in the analysis, NHANES data were combined across survey cycles from 1999 …

The Biosynthesis Of The Natural Product N-Nitroglycine, Gabriel Padilla

Graduate Studies Theses and Dissertations 2026

N-Nitroglycine (NNG) is a nitramine [R(R′)N–NO2; R′=H or alkyl] natural product (NP) produced by certain actinomycetes, such as Streptomyces noursei. At the beginning of this project, the biosynthesis of this NP was unknown. The goal was to determine how NNG and its nitramine moiety are enzymatically formed. This could lead to the discovery of novel nitramine NPs with diverse applications as well as alternative/green synthesis of nitramine explosives. This work begins by examining diverse biochemical N–N bond formation strategies. Nitrogen cycle enzymes, nitration of NPs, kutzneride biosynthesis, the aspartate/nitrosuccinate superfamily, hydrazinoacetic acid (HAA) biosynthesis, and streptozocin biosynthesis are among the …

Human-Centered Governance Of Climate Resilience: Integrating Sustainability, Equity, And Mental Health, Chelcee A. Pangerl

Graduate Studies Theses and Dissertations 2026

This dissertation examines how sustainability and resilience are defined, implemented, and experienced across three levels of climate governance: household perception, community experience, and federal policy. Climate resilience is often evaluated through infrastructure performance, emissions targets, restoration timelines, and preparedness systems, yet these measures do not fully capture how residents experience uncertainty, support, equity, and mental health. To address this gap, the dissertation develops and applies the Integrated Policy Framework for Sustainability and Resilience (IPFSR). IPFSR organizes six domains into three functional categories: policy outcomes, human-centered dimensions, and implementation mechanisms. Sustainability and operational/physical resilience are treated as policy outcomes; mental health …

Toward Evidence-Based Disposition Assessment In Counselor Education: Advocating For Established Measures And Evaluating The Psychometric Properties Of The Pdca-Ra, Laura Rendon Finnell

Graduate Studies Theses and Dissertations 2026

Professional dispositions are recognized as an essential component of counselor competence and are now explicitly included within accreditation standards. However, questions remain regarding how these characteristics should assessed in ways that are fair, systematic, and supported by empirical evidence. This two-manuscript dissertation focused on professional disposition assessment in counselor education. The first manuscript provides a conceptual examination of professional dispositions, counselor competence, and gatekeeping responsibilities while reviewing established disposition assessment instruments in counselor education. The manuscript advocates for the use of established disposition measures rather than relying solely on locally developed assessment procedures. The second manuscript presents an empirical evaluation …

Advancing Cyber-Physical Security And Resilience Of Modern Power Systems: Intelligent Monitoring, Secure Operation, And Resilient Recovery, Md Moshiur Rahman

Graduate Studies Theses and Dissertations 2026

Modern power distribution systems are rapidly evolving into cyber-physical, DER-rich, and data-driven networks that rely on extensive sensing, communication, automation, grid-edge intelligence, and operator decision support. While this transformation improves flexibility, observability and controllability, it also expands the cyber-attack surface and increases the risk that cyber intrusions can propagate into physical disturbances, compromised DER operation, degraded situational awareness, and interrupted service continuity. This dissertation advances the cyber-physical security and resilience of modern distribution systems by developing a high-fidelity real-time cyber-physical hardware-in-the-loop testbed using OPAL-RT, EXata CPS, industrial relays, SCADA/RTAC, HMI, and grid-edge devices to emulate realistic DER-integrated distribution grid operation. …

The study also examined principals' perceptions of culturally proficient leadership and principal preparation program attributes considered essential for leadership readiness in high-needs school settings. Guided by the Culturally Responsive School Leadership (CRSL) framework, data were collected through semi-structured interviews with 10 principals serving in urban Title I …

Communication-Aware Energy Optimization For Electric Vehicles With Adaptive Cruise Control, Shahriar Shahram

Graduate Studies Theses and Dissertations 2026

This dissertation develops information-driven methods to reduce traction energy in battery electric vehicles during adaptive and cooperative cruise control. Physics-grounded energetics are embedded in a predictive controller that accounts for intermittent V2V preview, sensing noise, packet loss, and powertrain limits. To ensure deployability, the nonconvex traction–power map is replaced by locally convex surrogates so each step solves a small, strictly convex QP in real time (average ≈ 70 ms/step on a desktop CPU: 8 cores/16 threads, 4.2–5.0 GHz), leaving margin at typical sampling rates (Ts =0.05–0.10 s; N=15–25).

Across standardized drive cycles from NREL DriveCAT—including FTP–75 (light duty), NREL Class …

Concept Drift Detection For Streaming Data Using One-Class Classification, Poorna Sandamini Senaratne

Graduate Studies Theses and Dissertations 2026

Modern machine learning systems are increasingly deployed in streaming environments where data arrive sequentially and the underlying data-generating process may evolve over time. This phenomenon, known as concept drift, can significantly degrade model performance if not detected and addressed in a timely manner. This dissertation proposes a principled framework for concept drift detection based on one-class classification, integrating neural network embeddings with Support Vector methodologies.

The proposed approach leverages neural networks to learn compact and informative embeddings of input data, capturing complex nonlinear structures in a lower-dimensional latent space. These embeddings are then used to construct a statistical description of …

Visual Cues Of Human-Likeness, Not Salience, Impact Trust-Related Human-Computer Interaction, Jordan Schotz

Graduate Studies Theses and Dissertations 2026

As interactions with digital agents become increasingly integrated into daily life, understanding how visual representations influence social decision-making is critical. Previous research in human-computer interaction has frequently confounded the psychological effects of an agent's perceived human-likeness with the underlying visual salience of the stimuli. To address these persistent gaps, the present study systematically isolated the effects of human-likeness and visual cue trustworthiness on trust behavior while controlling for objective image properties. The present study expanded on and normed the Virtual Avatar Facial Stimuli Set (VAFSS), a comprehensive database comprising hundreds of identity-matched photographs and computer-generated avatars varying across a spectrum …

Online Risk And Harm For Marginalized Users: How Social Influence Amplifies Or Mitigates Vulnerability, Tangila Islam Tanni

Graduate Studies Theses and Dissertations 2026

Social media has reshaped how people connect, communicate, and influence one another, yet these environments also create harms that disproportionately affect marginalized users. Participation in online communities can expose users to identity-based harassment, emotional distress, and the normalization of harmful attitudes, shaping identity, well-being, and participation online and offline. Prior work has documented many forms of online harm, yet less is understood about how harmful norms and behaviors are reinforced across different forms of social media interaction, from private direct messages to online communities. Guided by the Social Ecological Model, this dissertation investigates how online harms toward marginalized users emerge …

Careless Responding: Testing The Theory Of Vigilance, Rusty Wilson

Graduate Studies Theses and Dissertations 2026

Careless responding (CR) has been identified as a threat to the psychometric integrity of cognitive and non-cognitive tests, with much of the current research focusing on the identification and removal of carelessness from dataset. While this research has proved fruitful in improving data quality, there has been a recent push to move towards preventing carelessness as opposed to post-hoc removal, which harms statistical power. However, the most common prevention strategy to prevent carelessness (pre-survey warnings) has shown equivocal effects. Additionally, the literature lacks an agreed upon theory to explain why carelessness occurs. To address these gaps I introduce theory from …

From Perspectival Myopia To Professional Transformation: An Autoethnographic Retrospection Of A High School Principal From Nepal, Shankar Dhakal, Geoffrey W. Lummis, Andrew Jones

Research outputs 2022 to 2026

This paper presents a re-storied account of my (lead author) decade-long (2007–2017) professional journey as a high school principal in diverse educational settings in Nepal. Using an autoethnographic approach, I have theorized my leadership transformation approaches through professional storytelling, employing critical reflexivity to trace intimate leadership experiences where authoritarian approaches to leadership, disparities, and inequalities in schools run rampant. My perspectival myopia, professional vulnerabilities, and the discrepancies between my leadership ideals and behaviors resulted in issues such as perceptions of disengagement, underperformance, and dissatisfaction on the receiving end, prompting me to contemplate professional transformation. While outlining several significant steps and …

The Hows And Whys Of Gendered Grouping Practices In Primary Physical Education In England, Shaun D. Wilkinson, Annette Stride, Dawn Penney

Research outputs 2022 to 2026

Background: Single- and mixed-sex grouping have long been a focus of attention in physical education (PE) and are matters often at the fore of discussions about curriculum planning, teaching, and learning. Nonetheless, there remains little consensus or guidance on which approach (or combination of approaches) should be preferred in PE in primary and secondary schools in England. Further, while single- and mixed-sex grouping have been extensively researched in PE in secondary schools, hitherto there remains an absence of research examining these practices in PE in primary schools. This research sought to address gaps in the literature to build a stronger …

The Transformational Possibilities Of Liberal Vocationalism: A Case Study Of Post-Year 10 Outdoor Education In Western Australia, David Aldous, Dawn Penney

Research outputs 2022 to 2026

This paper discusses the transformative potential that liberal vocationalism, aligned with contemporary visions of lifelong and lifewide learning, presents for outdoor learning across institutional and industry settings. Utilising Bernstein’s sociological theory, the paper explores this transformation through an illustrative case study of the relations, knowledges and identities of post-Year10 Outdoor Education in Western Australia (WA). The case study highlights how Outdoor Education in WA has been organised through distinct classificatory relations that exist between government, regulatory bodies and individual industry providers that serve to distinguish Outdoor Education from outdoor learning that is ongoing and able to be pursued by people …

Reclaiming Constitutional Authority Of Algorithmic Power, Yiyang Mei, Michael J. Broyde

Faculty Articles

Whether and how to govern AI is no longer a question of technical regulation. It is a question of constitutional authority. Across jurisdictions, algorithmic systems now perform functions once reserved to public institutions: allocating welfare, determining legal status, mediating access to housing, employment, and healthcare. These are not merely administrative operations. They are acts of rule. Yet the dominant models of AI governance fail to confront this reality. The European approach centers on rights-based oversight, presenting its regulatory framework as a principled defense of human dignity. The American model relies on decentralized experimentation, treating fragmentation as a proxy for democratic …

The “Green Persuasion Effect” Of Negative Messages: How And When Message Framing Influences Tourists’ Environmentally Responsible Behavior, Xuehuan He, Chengzhi Ye, Songshan Huang, Lujun Su

Research outputs 2022 to 2026

Tourist activities may harm the environment, making tourists’ environmentally responsible behavior particularly important in tourism research. This research investigates the persuasion effect of message framing in environmental protection reminders on environmentally responsible behavior. Through five studies employing both field and controlled experiments and different measures of environmentally responsible behavior across varied tourism scenarios, we demonstrate that negatively (vs. positively) framed messages more effectively increase environmentally responsible behavior. Specifically, negatively framed messages are more effective in enhancing tourists’ environmental awareness, which triggers more environmentally responsible behavior. Furthermore, we identify social class as a moderator of message framing effectiveness, showing that negatively …

Curriculum Approaches To Strengthening Student Employability And Improving Graduate Outcomes In The Stm Disciplines, Denise Jackson, Michael D. O’Connor

Research outputs 2022 to 2026

In Australia and elsewhere, curriculum improvements are needed to improve the development of Science, Technology and Mathematics (STM) graduates for future work and careers. Several studies document significant STM student attrition, poor graduate preparedness for work, relatively weak employment rates post-graduation, and mismatched expectations of graduate capabilities by employers. The inclusion of work-integrated learning (WIL) activities within curricula can better prepare students for relevant employment by bridging discipline-specific teaching with work practices. Traditionally, access to WIL has been limited for STM Bachelor students and a better understanding of WIL’s benefits and impact is needed to refine and extend STM WIL …

The aim of this paper is to outline the importance of defining ageing, the semantics and indicators used, and to identify common challenges for health professionals' understanding and application of a healthy ageing approach in their everyday clinical practice. Design and Methods: This discursive paper demonstrates how realistic ageing indicators are for highlighting the variation and impact of challenges associated with ageing. It …

Australian University Websites As Colonialities Of Gender, Emily M. Gray, Ampersand Pasley, Emma Fishwick, Mindy Blaise, Jacqueline Ullman, Maria Delaney

Research outputs 2022 to 2026

This paper offers analysis of the first phase of a research project, Understanding and Addressing Everyday Sexisms in Australian Universities. This phase involved a critical content analysis of all 39 of Australia’s public university websites, focusing on how they represent gender, absences in relation to gender and the navigability of the websites in relation to gender equity policy. Drawing on Maria Lugones’s colonialities of gender, this paper demonstrates how university websites have the potential to reproduce or renegotiate inherited institutional everyday sexisms and broader gender inequities. Themes of reconfiguring acceptable gendering, conspicuous absences, and in-built obscurity that emerged from this …

The Role Of Games In Hospitality Management Education, Arghavan Hadinejad, Samira Zare

Research outputs 2022 to 2026

Building upon game-based learning, this study compares hospitality students’ cognition, metacognition, engagement, satisfaction, and performance in a course across two academic terms at an Australian university. One term featured teaching content without any games while the second term incorporated gamification. A quasi-experimental design was used in which surveys, interviews and students’ evaluation reports were utilized. Students demonstrated more favorable cognitive thoughts, and higher levels of engagement and satisfaction in the gamified course. Students’ performance in assessments across the two courses as well as their metacognition were found to be similar. This study presents a game effectiveness matrix with Kahoot as …
