Predicting Tilt In Esports: A Psychophysiological Approach To Understanding Player Emotional Regulation, Nathan Rhea

University of the Pacific Theses and Dissertations

Emotional regulation and stress management are important to both casual and competitive esports players. When players become dysregulated, they experience a phenomenon known as “tilt” within the gaming community, where they often lose control of their emotions and their performance declines. This study aimed to investigate whether a psychophysiological variable in heart rate variability could predict tilt in college-age esports players. Additionally, the relationship between heart rate variability and emotions predicted by the Tiltometer system with gameplay performance and winning or losing was tested.

This study used a quantitative correlational research design. Participants for this study were college-age players (N=23) …

Lost In Instructions: Study Of Blind Users' Experiences With Diy Manuals And Ai-Rewritten Instructions For Assembly, Operation, And Troubleshooting Of Tangible Products, Monalika Padma Reddy, Aruna Balasubramanian, Jiawei Zhou, Xiaojun Bi, Iv Ramakrishnan, Vikas Ashok

Computer Science Faculty Publications

AI tools like ChatGPT and Be-My-AI are increasingly being used by blind individuals. Although prior work has explored their use in some Do-It-Yourself (DIY) tasks by blind individuals, little is known about how they use these tools and the available product-manual resources to assemble, operate, and troubleshoot physical/tangible products – tasks requiring spatial reasoning, structural understanding, and precise execution. We address this knowledge gap via an interview study and a usability study with blind participants, investigating how they leverage AI tools and product manuals for DIY tasks with physical products. Findings show that manuals are essential resources, but product-manual instructions …

Clickwrap Accountability, Alicia Solow-Niederman

GW Law Faculty Publications & Other Works

Picture a public-facing generative AI chatbot on a government website that can answer questions about benefits eligibility.  Systems like these expose a sociotechnical-legal divide: they route around the standard due process framework, because there has been no formal government determination, yet they induce reliance from users, above and beyond past rounds of automated legal guidance.  Moreover, if there is an error, current doctrine on government errors and equitable estoppel makes relief unlikely.

This Essay focuses on government deployment of public-facing generative AI chatbots and critically assesses the front-end power dynamics that determine who is filtered out of government programs before …

Fabrication Of Urea With Amorphous Silica To Increase Rice Growth In Saline Soils, Thi Ha Chi Nguyen, Thi Hang Thuc Ha, Minh Phuong Nguyen, Ngoc Chuc Pham, Quang Bac Nguyen, Nguyen Huy Tuan Do, Ngoc Nhiem Dao, Trung Kien Nguyen

Applied Environmental Research

In recent decades, the decrease in rice cultivation areas in Vietnam, particularly in the Mekong River Delta, caused by climate change and soil salinization, has posed serious challenges for sustainable development. In addition to irrigation and agronomic practices, fertilizers that sustain rice growth under saline conditions play a crucial role in improving crop productivity. Amorphous silica has been reported to increase plant tolerance to drought, salinity, and heavy metal stress. In this study, nanosilica-coated urea (UCS) fertilizers were synthesized by coating urea granules with 1–5 wt% amorphous silica. The products were characterized by SEM, XRD, FTIR, TG‒DSC, and EDX to …

Structural Inequities, Environmental Toxicants, And Cardiometabolic Pathways In Cardiovascular Disease: Evidence From A Nationally Representative U.S. Population, Ese F. Oghaghare

Electronic Theses & Dissertations (2024 - present)

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality in the United States and continues to disproportionately burden racial/ethnic minorities and socioeconomically disadvantaged populations. Traditional risk factors and behavioral explanations fail to fully account for these persistent disparities, motivating increased attention to intermediate biological pathways and environmental toxicant exposures through which structural inequities may become biologically embedded. This dissertation investigates how cardiometabolic biomarkers, diet quality, and exposure to persistent organic pollutants jointly contribute to cardiovascular disease risk in a nationally representative U.S. population.

Using data from the National Health and Nutrition Examination Survey (NHANES), three complementary studies were …

After The Aid Boom: Government Responses To The Global Health Agenda And Political Commitment In Low- And Middle-Income Countries, Sana Abdelkarim

Electronic Theses & Dissertations (2024 - present)

How do governments respond to the global health agenda? Does external health assistance translate to sustained domestic political commitment in low- and middle-income countries? Over the past three decades, development assistance for health has expanded, accompanied by international agreements emphasizing country ownership, alignment, and domestic resource mobilization. Yet domestic fiscal commitment to health remains uneven across countries. These questions have become more pressing as the global aid landscape enters a period of contraction, with a significant decline in development assistance, including health financing, raising concerns about the sustainability of health systems that have become reliant on external support.  This raises …

Genomic Determinants Of Appetite Regulation And Their Role In Obesity Risk, Timothy J. Renier

Dartmouth College Ph.D Dissertations

Over 40% of US adults and 20% of children live with obesity. It is related to increased risks of diseases including type II diabetes and cancer, is a source of harmful stigma, and impairs child development. Appetitive traits describing patterns of food approach and avoidance behaviors may serve as windows into the underlying pathophysiology of obesity. As both obesity and appetitive traits are heritable, common genetic drivers of obesity may lead to phenotypic obesity through appetitive traits as a disease mechanism. Additionally, GLP-1 receptor agonists (GLP-1RAs) have been shown to exert their profound clinical effects in part by modulating appetite. …

Cross-Temporal Statistical Approaches For Evaluating Predictor-Outcome Relationships, Jeff Joseph

Dartmouth College Ph.D Dissertations

Central auditory function is linked with cognitive deficits, but few research projects use existing statistical approaches or develop new ones to forecast cognitive deficits using the results of central auditory tests. To address this limitation, we use a series of statistical learning frameworks for predicting a child’s cognitive abilities based on his/her central auditory performances and demographic factors. Two key challenges exist. First, children may start the study at a time when they are unable to perform the central auditory tests or cognitive tests. Second, cognitive performance is age-dependent, particularly in the early formative years of childhood and adolescence. To …

Understanding Dementia Challenges In Rural Ghana: A Systematic Review, Diana Maame Agyeiwaa Agyei, Sesi Sedegah, Abena Abokoma Asemanyi, Theresa Ayertey, Wendy Yeboah

Iowa Journal of Communication

Dementia poses an escalating public health challenge in Ghana due to an expanding aging population, yet rural awareness remains critically low. Guided by Mohan Dutta’s Culture-Centered Approach (CCA), this PRISMA-compliant qualitative systematic review synthesized ten peer-reviewed articles to examine cultural perceptions and lived experiences surrounding dementia in rural Ghana. The findings highlight that cognitive decline is widely misattributed to witchcraft or normalized as standard aging. Witchcraft misconceptions subject individuals—especially older women—to severe stigmatization, social exclusion, physical abuse, and banishment to "witch camps". Meanwhile, normalizing symptoms as ordinary aging delays critical medical care and shifts family decision-making away from patients. Furthermore, …

Parental Distress, Coercive Control With Food, And Child Self-Regulation, Kattie Nguyen

UNF Graduate Theses and Dissertations

Self-regulation is the management of one's emotions, thoughts, and behaviors to adapt to a situation (Smith-Donald et al., 2007). During infancy and toddlerhood, parents foster self-regulation through co-regulation (e.g., sensitivity, responsiveness), helping children manage their emotions, behaviors, and thoughts (Butler & Randall, 2013). Parents who experience distress (e.g., depression, stress, anxiety) are more likely to use less responsive and harsher, controlling practices like coercive control. Coercive control with food is a practice where parents use food as threats or bribes to control their child’s emotions and behaviors (Vaughn et al., 2016). The present study examined the associations between parental distress, …

Physical Activity And Health Outcomes In Children With Dyslexia During Summer Versus School Months, Tina J. Glatz

Graduate Studies Theses and Dissertations 2026

Children in the United States continue to experience rising rates of overweight and obesity. Children with learning disabilities are twice as likely to have obesity than typically developing peers, partly due to difficulties with motor skills and behavior regulation. The purpose of this study was to examine and compare differences in health outcomes and physical activity (PA) during summer versus school months in children with dyslexia, using a within- subject study design.

At three timepoints (May, August, December 2025), children’s height, weight, and fitness were measured via a portable stadiometer, dual-frequency foot-to-foot bioelectric impedance device, and Progressive Aerobic Cardiovascular Endurance …

Viral Dynamics Across Managed And Wild Pollinators: Integrating Immunity, Ecology, And Community Structure, Allison Malay

Graduate Studies Theses and Dissertations 2026

Managed honey bees (Apis mellifera) are critical agricultural pollinators, yet colonies continue to experience persistently high losses across North America and Europe. These declines are driven by interacting stressors, including parasites, pathogens, nutrition, and landscape context. Viral pathogens are key contributors to colony morbidity and mortality, but the processes governing variation in viral prevalence, load, and host response remain incompletely understood. This dissertation investigates how viral dynamics in honey bees emerge from interactions among host immunity, colony condition, environmental context, and pollinator community structure. By integrating measures of viral prevalence, viral load, and immune gene expression across multiple …

Policy Into Practice: Exploring School Counselors' And School Psychologists' Knowledge And Sensemaking Towards The Application Of Alternative Gifted Identification Criteria For Lower Socioeconomic Students, Brittany E. Hague

Graduate Studies Theses and Dissertations 2026

Persistent underrepresentation of students from lower socioeconomic status (SES) backgrounds in Gifted education reflects long-standing structural inequities embedded in identification policies and practices. In response, many Florida school districts have adopted equity-oriented identification reforms, including universal screening, local norms, and multiple-measure approaches. However, policy equity does not automatically translate into equitable outcomes; rather, it is mediated through the interpretive work of school-based practitioners. Guided by Sensemaking Theory, this convergent mixed-methods study examines how school counselors and school psychologists construct meaning around alternative Gifted identification criteria and how their beliefs, professional judgment, and organizational contexts shape implementation. The study explores how …

Puff, Puff, Pass? Examining Cannabis Use Among Black American Adults, Christopher B. Walker

Graduate Studies Theses and Dissertations 2026

In the United States, cannabis has become one of the most widely used controlled substances due to its increase in social acceptance, the growing number of states legalizing it for medical and non-medical purposes, and the expansion of consumption methods.  However, little is known about the modes of cannabis use chosen by Black American adults.  This population is of importance due to existing research suggesting their increased risk of developing cannabis use disorder compared to their White counterparts and their underrepresentation in existing literature.  The goal of this study is to examine cannabis use among Black adults in the U.S., …

Homoplasy Of Maxillary Orthognathism In Derived Homo, Jared Jordan

Graduate Studies Theses and Dissertations 2026

The evolution of the orthognathic condition in the genus Homo represents a monumental transition toward the facial morphology of modern humans from that of earlier hominins, but the phylogenetic positioning of this transformation remains poorly understood. This study investigated temporal trends in maxillary and mandibular prognathism in the genus Homo, and whether maxillary and mandibular shortening in East Asian H. erectus and later East Asian Middle Pleistocene Homo (e.g., Homo longi) represent independent derivations of orthognathic morphology, thereby making orthognathism a homoplasy in the genus Homo. Using a sample of roughly 109 cranial and mandibular specimens spanning …

Seasonal Variations In Co2 Emission From Poultry Manure-Amended Soils In Two Contrasting Tropical Agroecosystems, Gladys M. Akande, Adebayo J. Adeyemo, Chidozie J. Oraegbunam, Iduh J.J. Otene, Ezekiel C. Are, Babatunde S. Ewulo, Chioma M. Ahukaemere, Samuel O. Kolawole, Sunday E. Obalum

Applied Environmental Research

The soil remains the largest carbon sink, the capacity of which varies spatiotemporally and with anthropogenic activities, with implications for carbon dioxide (CO2) emissions and associated global warming. Despite the increasing popularity of organic amendments in the ecologically and anthropoculturally diverse farming systems of tropical Africa, manure-induced CO2 emissions in this region with high soil-carbon-sequestration potential are poorly documented. This study assessed seasonal CO2 emissions from poultry manure-amended sandy-clay-loam and sandy-loam soils in the Rainforest-Savannah and Southern Guinea Savannah zones, respectively, of Nigeria. Following manure application at 3 rates (0, 10, and 15 t ha-1), soil samples were collected during …

The Structure, Dynamics, And Impact Of An Interbacterial Weapon Encoded By Human Gut Bacteria, Casey John Latario

Dartmouth College Ph.D Dissertations

The human gut is densely colonized by diverse bacteria. Over a human’s growth, the GI tract becomes a dynamic community that is subjected to a continual in-flow of nutrients and would-be colonizers and an out-flow of microbes and waste products. Despite these dynamics, the bacterial community often displays stability, with particular strains persisting over decades. These stable colonizers have evolved mechanisms to bolster their colonization, resist disruption by other microbes, and persist through environmental flux.

Both interbacterial competition and horizontal gene transfer (HGT) contribute to colonization and survival within the GI tract. A major mechanism for interbacterial competition is the …

Data-Driven Prediction Of Compressive Strength In Pofa-Modified Concrete: A Comparative Study Of Lr, Nlr, And Ann Models, Shuaaib A. Mohammed, Hawdin Ismael Ibrahim, Diar Fatah Abdulrahman Askar, Hersh F Mahmood, Mehdi Khodaei, Soran Abdrahman Ahmad

Mansoura Engineering Journal

Production of concrete results in high CO₂ emissions, high energy demand, and consumption of various raw materials; however, it is one of the most widely used materials in construction to date. Therefore, researchers aim to minimize the impact of concrete production through various methods, such as introducing sustainable sources of materials that can be used in concrete. For instance, agricultural waste materials can be used as partial cement replacement. This study presents a comprehensive data-driven analysis of the effects of POFA on the properties of normal-strength concrete. By synthesizing a database of 196 experimental datasets from existing literature, three …

Federated And Explainable Spiking Neural Networks For Fair And Privacy-Preserving Nail Disease Diagnostics, Ch Pavani Reddy, Krishnanaik Vankdoth

Mansoura Engineering Journal

Automated nail disease diagnostics provide a non-invasive pathway for identifying underlying systemic health conditions; however, conventional centralized deep learning approaches often raise concerns related to privacy, fairness, and interpretability. Although the original NeuroNail-SNN framework demonstrated an energy-efficient and edge-ready diagnostic solution, its broader clinical adoption remained limited by unresolved trust, transparency, and ethical considerations. In this study, we propose the Federated and Explainable NeuroNail-SNN, which extends the original spiking neural architecture by integrating federated learning (FL), explainable artificial intelligence (XAI), fairness evaluation, and uncertainty quantification within a unified framework. Federated learning enables decentralized model training across hospitals and mobile clinics …
