Internal Medicine, East Africa

Background: Stroke is a leading cause of death and disability globally, with sub-Saharan Africa, bearing the greatest burden. Tanzania has only one active stroke registry, limiting evidence-based care and policy development. We aimed to expand the registry into a multi-centre study across eight major tertiary hospitals to generate baseline data for a national stroke registry.

Methods: From January to August 2024, we analysed de-identified data from adults (≥18 years) admitted with a World Health Organisation defined stroke. Data collected included demographics, risk factors, imaging, and in-hospital mortality. Logistic regression identified predictors of mortality.

Results: A total of 1000 patients were …

Bayesian Machine Learning Enables Discovery Of Risk Factors For Hepatosplenic Multimorbidity Related To Schistosomiasis, Yin-Cong Zhi, Victor Anguajibi, John Oryema, Betty Nabatte, Christopher Opio, Narcis Kabatereine, Goylette Chami

Internal Medicine, East Africa

One in 25 deaths worldwide is related to liver disease, and often with multiple hepatosplenic conditions. Yet, little is understood of the risk factors for hepatosplenic multimorbidity, especially in the context of chronic infections. We present a novel Bayesian multitask learning framework to jointly model 45 hepatosplenic conditions assessed using point-of-care B-mode ultrasound for 3155 individuals aged 5-91 years within the SchistoTrack cohort across rural Uganda, where chronic intestinal schistosomiasis is endemic. We identify distinct and shared biomedical, socioeconomic, and spatial risk factors for individual conditions and hepatosplenic multimorbidity, and introduce methods for measuring condition dependencies as risk factors. Notably, …

Methods: We used descriptive statistics and generalized estimating equation models adjusted for covariates to assess the relationships among hyperpolypharmacy, …

Does Ethnicity Similarity Affect Analyst Forecasts?, Zichen Tian

Dissertations and Theses Collection (Open Access)

I examine whether ethnicity similarity between sell-side analysts and corporate senior officers shapes analysts’ forecasting behavior. The baseline results show that ethnicity similarity is associated with higher forecast frequency and larger initial forecast errors. Importantly, I find that the larger initial forecast error associated with ethnicity similarity comes from overestimation and disappears for analysts’ last forecasts, consistent with bias coming from innate favoritism and dissipating as public information accumulates within the fiscal year. However, the market does not discount coethnic analysts’ first forecast revisions and reacts more strongly to their last forecast revisions within the fiscal year, suggesting that investors …

A Scalable Iteration Of The Horizon Simulation Framework Using Multithreading Techniques, Jason E. Beals

Master's Theses

The Horizon Simulation Framework (HSF) occupies a unique space in the modern aerospace modeling landscape, enabling flexible, modular modeling of mission-level agent behavior through an object-oriented, hierarchical design. HSF's hallmark breadth-first search scheduling algorithm explores a "multiverse" of possible mission execution pathways, enabling exhaustive evaluation of schedule combinations against user-defined heuristics.

As aerospace systems become increasingly complex, HSF faces critical challenges in establishing verifiable, deterministic behavior. The framework's core scheduling algorithm had not undergone systematic validation, leaving questions about temporal consistency, state management correctness, and reproducibility across different program executions. Furthermore, the exponential growth of schedule combinations creates computational bottlenecks …

Diversity And Immune Dynamics Of Choroid Plexus Macrophages Are Shaped By Distinct Developmental Origins, Siling Du, Khai M Nguyen, Alina Ulezko Antonova, Jose L Fachi, Patrick Fernandes Rodrigues, Alice Verdiani, Martina Molgora, Igor Smirnov, Jasmin Herz, Tornike Mamuladze, Jennifer Ponce, Amanda Swain, Mattia Bugatti, Susan Gilfillan, Marina Cella, William Vermi, Jonathan Kipnis, Marco Colonna, Simone Brioschi

The Brown Foundation: Institute of Molecular Medicine

The choroid plexus forms a key barrier and signaling interface between the brain and peripheral circulation, yet its immune landscape remains incompletely understood. Using single-cell transcriptomics combined with lineage and spatial tracing methods, we identified three biologically distinct populations of choroid plexus macrophages, defined by differential expression of CD163, MHCII or CD9. These subsets arise from separate hematopoietic waves, occupy distinct anatomical niches and differentially rely on CSF1 and IL-34 for survival. We found that TGFβ signaling is essential to maintain their tissue-specific identities, and deletion of Tgfbr2 in these cells induces broad phenotypic reprogramming. During neuroinflammation, choroid plexus macrophages …

Artificial Intelligence Capabilities, Generational Involvement, And Competitive Performance: Case Of Tunisian Family Businesses, Rim Gafsi

Journal of Global Business Insights

Anchored in Dynamic Capabilities Theory, this study examines the effect of Artificial Intelligence (AI) capabilities on the competitive performance of family firms and the moderating role of generational involvement. Using survey data from 120 Tunisian family firms adopting AI between 2021 and 2024 and applying confirmatory factor analysis and structural equation modeling, the findings show that AI capabilities significantly enhance firm performance, while generational involvement has no moderating effect. This challenges the assumption that intergenerational transitions inherently drive innovation and provides novel evidence from Tunisia that performance gains stem primarily from the strategic integration of AI rather than generational dynamics. …

Does Abusive Supervision Undermine Creativity? A Buffering Role Of Absorptive Capacity, Sayma H. Shetu, Md. Sanaul Islam, Abdul G. Khan, Md. Shahed Mahmud

Journal of Global Business Insights

This study investigates the underlying processes of this relationship by examining knowledge hiding as a mediator and absorptive capacity as a moderator, within the context of the Conservation of Resources (COR) theory. 385 garment sector employees in Bangladesh were surveyed using a three-wave questionnaire, and the results were analyzed using partial least squares structural equation modeling. The study's findings demonstrate that abusive supervision negatively impacts employee creativity, in part by increasing knowledge hiding. Furthermore, higher absorptive capacity mitigates these adverse effects, reducing knowledge-hiding tendencies and enhancing creative performance. Theoretically, this study advances COR theory by identifying knowledge hiding as a …

Tourists’ Perceptions Of Autonomous Vehicles: A Qualitative Approach, Nese Yilmaz, Eda Ozgul-Katlav, Ozan Atsiz

Journal of Global Business Insights

This study examines travelers’ perceptions and attitudes toward autonomous vehicles (AVs) in tourism destinations. Adopting a qualitative approach, data were collected through semi-structured interviews with 20 travelers and analyzed using content analysis. Drawing on a cognitive–affective perspective, the findings reveal that travelers’ evaluations of AVs are shaped by both perceived advantages and disadvantages, which are closely linked to their perceptions and emotional responses. The results further indicate that cognitive (perceptions) and affective (feelings) responses are associated with behavioral intentions, including destination choice and willingness to pay for AV services. While many participants expressed positive expectations regarding convenience and novelty, concerns …

Design And Development Of A 12-Degree-Of-Freedom Quadruped Robot, Kai De La Cruz

Master's Theses

This thesis presents the design, analysis, and experimental validation of a 12-degree-of-freedom (DOF) quadruped robot developed as a research platform for legged locomotion and control. The system builds upon the Cal Poly Legged Robotics Group’s prior 8-DOF quadruped, addressing key limitations in manipulability, load distribution, and mechanical robustness by introducing a 3-DOF leg architecture.

The mechanical design emphasizes lightweight construction, structural integrity, and modularity to support future research extensions. Static and dynamic loading models were developed to inform component sizing and material selection. A carbon-fiber chassis and redesigned leg assemblies were fabricated and validated through finite element analysis and physical …

Sea Level Trends Near Critical Levees In The Sacramento-San Joaquin Delta, Reyna Sanchez Gomez

Master's Theses

The Sacramento-San Joaquin Delta (Delta) levee system faces threats from rising sea levels, land subsidence, and deteriorating levees, all of which pose risks to California’s primary surface water supply. The purpose of this thesis is to assess relative sea level rise (RSLR) and estimate the spatially varying factors that influence water levels in the Delta. This thesis extends the work of Baranes et al. (2023) to the period 1975-2022 by appending recently acquired water-level records (1975-1982) to modern datasets (1982-2022) from 10 water-level stations. These water level datasets were digitized, quality-assured, and referenced to a common geodetic datum, as described …

Designing For Trust In Chat-Based Question Answering Systems: An Exchange-Based Retrieval Approach, Nathan Mccutchen

Master's Theses

Community chat platforms such as Discord and Slack support spontaneous, collaborative communication but make it difficult to retrieve previously discussed information. As conversations accumulate, valuable exchanges become buried, leading to repeated questions and sustained burden on experienced community members.

This work contributes a set of design requirements for question-answering systems operating over unstructured chat data, a Discord bot prototype implementing those requirements named Echo, and an empirical evaluation of how such a system affects user trust. Rather than encoding discrete question-answer pairs or generating synthetic responses with a language model, Echo indexes conversation topics for semantic retrieval and presents results …

Environmental Impact Of Preventative Fire-Retardant Applications On Soil Water Chemistry, Patrick C. Michelsen

Master's Theses

Between 1992 and 2012, 84% of all documented wildfires were started by humans. These fires often start around high-risk locations such as power lines and roadsides where fuel loads are near these potential human-caused ignition sources. Point source ignition sites that are surrounded by shrubs or grasslands are especially important because fires that occur within these biomes are responsible for far more destruction of property than forest fires. One strategy that is effective at mitigating the spread of fires from ignition sites that are within grassland or shrub biomes are preventative fire-retardant products (PFRPs). These PFRPs differ from traditional fire-retardant …

A Ship Between Worlds: Illicit Trade, Empire, And Enslavement In The Voyage Of The Nuestra Senora De Las Nieves, 1819-1820, Carly Eastham

Master's Theses

This study examines the illicit Spanish transatlantic slave trade to Cuba during the post-abolition era through a microhistorical analysis of the 1819 voyage of the schooner Nuestra Señora de las Nieves. Despite international efforts to suppress the trade following abolition treaties, this voyage illustrates how Spanish traders adapted their practices to continue trafficking enslaved Africans, fueling Cuba’s booming sugar economy amid shifting geopolitical and economic pressures. Drawing on primary documents seized by the British navy and analyzed alongside relevant secondary scholarship, this research situates the Cuban trade within the broader Atlantic world’s complex cultural, legal, and economic transformations.

Human–Ai Interaction In Graduate Academic Work: A Job Demands-Resources Conceptualization Of Satisfaction And Emotional Exhaustion, Joey Oliveira

Human Resource Development Student Publications and Presentations

Artificial Intelligence (AI) technologies are increasingly embedded in graduate academic work, shaping how faculty and students perform cognitive, analytical, and knowledge-based tasks. As AI tools become integrated into writing, research, and instructional activities, human–AI interaction has emerged as a central feature of contemporary academic work environments. However, existing research has largely focused on AI adoption and technological capability, with limited attention given to how ongoing human–AI interaction influences well-being experiences in academic contexts. Drawing on the Job Demands-Resources (JD-R) framework, this conceptual paper develops a model that links human–AI interaction to student learning satisfaction, faculty job satisfaction, and emotional exhaustion. …

Perspectives Of University Leaders On Adoption And Scaling E Mental Health Support For Students: An Exploratory Analysis, Choongo Mulungu, Esin Nisan Yildirim

Journal of Human Services: Training, Research, and Practice

ABSTRACT

University students face rising mental health challenges, yet adoption of digital support services in higher education remains limited, especially in the Global South. This qualitative study explored perceptions of 18 senior administrators from universities across Africa, Europe, Asia, and North America. Findings revealed a significant implementation gap, with few institutions offering formal platforms. Leaders cited barriers including limited institutional prioritisation, counsellor overload, financial ambiguity, ethical concerns, and absent policy frameworks. Addressing these challenges requires deliberate policy action, equitable resource allocation, and culturally responsive strategies for sustainable integration.

No-Show Characteristics Of Rural Clients With Mental Health Conditions, Christy R. Collins, Jose Carbajal

Journal of Human Services: Training, Research, and Practice

The purpose of this study is to report demographic characteristics and appointment compliance factors associated with no-show appointments in a rural clinical setting in East Texas. Describing these variables will expand the existing literature and offer greater clarity not only on why appointments are missed, but also on who is missing them. Therefore, understanding how sociodemographic variables relate to missed appointments may enhance appointment adherence and improve healthcare outcomes for individuals. This study used cross-sectional archival data specifically collected to examine missed appointments among clients at a rural clinic (N = 134). The results indicate that Hispanic/Latino individuals, clients aged …

Faith And Justice: Church Leadership's Impact On Prison Reform, Yaw Asamoah Akowuah Mr., Frank Y. Adusei, Eric Kaufman, Loy V. Crowder

Journal of Human Services: Training, Research, and Practice

This study examines the Church of Pentecost’s (CoP) pioneering prison reform initiative in Ghana as a faith-based response to systemic overcrowding and inadequate rehabilitation infrastructure. Through a qualitative case study design, the research analyzes in-depth interviews with church leaders and media staff, alongside institutional documents, to explore how religious leadership intersects with correctional policy. Findings reveal that CoP’s “Vision 2023” strategy positioned prison decongestion as a moral and national imperative, leading to the construction of five “Inmates Skills Acquisition and Reformation Centres.” These facilities integrate vocational training, spiritual care, and modern infrastructure, aligning with Rehabilitation Theory’s emphasis on humane, reintegration-focused …

Co-Occurring Vocal Symptoms In Speech-Language Pathologists: A Survey Study, Dawn M. Stanley

Journal of Human Services: Training, Research, and Practice

Vocal symptoms among speech-language pathologists (SLPs) are often overlooked in occupational voice research. In a profession where voice is the primary tool, SLPs usually neglect the instrument they ask others to protect. Vocal symptoms may arise due to high vocal demands in clinical and educational settings. Despite their expertise in communication disorders, SLPs remain an understudied population in vocal health. This study surveyed 202 SLPs to examine the experiences of vocal symptoms during clinical practice. Results indicated that SLPs reported co-occurrences of vocal effort and vocal fatigue 29 (22%) which can interfere with vocal quality when treating patients.

Social Skill Program Development For Adults With Intellectual And Developmental Disabilities, Clayton Stapert

Capstone Projects

This doctoral capstone experience (DCE) was completed at the Center for Disability Services (CDS) and focused on developing and implementing a social skills program for adults with intellectual and developmental disabilities (IDD). Many existing social skills programs focus on general or work-related skills, but there is a need for programs that help individuals apply social skills during real-life community activities. This project aimed to address that gap by creating a structured, occupation-based program within an adult day skill-building day center.

The program included education, group discussion, role-playing, and community outings to help participants practice skills such as interacting with cashiers, …

Conditions Affecting The Gi Tract: The Dental Professional’S Role, Sherri M. Lukes, Rdh, Ms, Faadh

The Journal of the Michigan Dental Association

This article explores the critical role dental professionals play in identifying gastrointestinal (GI) conditions through their oral manifestations. It provides an overview of various pathologies, including HPV-induced oropharyngeal cancer, gastroesophageal reflux disease (GERD), and inflammatory bowel diseases like Crohn’s and ulcerative colitis. The author describes specific oral signs, such as dental erosion and aphthous ulcerations, that can serve as early indicators of systemic disease. The piece advocates for an interdisciplinary approach to patient care, emphasizing that dental practitioners are often on the front lines of diagnosing serious systemic health issues.
