A Bayesian Late-Fusion Supportability Framework For Rare-Disease Severity Prediction In Glut1 Deficiency Syndrome, Jordan M. Rodriguez

Mathematics Dissertations

Glucose transporter type 1 deficiency syndrome (GLUT1-DS) is a rare neurometabolic disorder with heterogeneous neurological and developmental severity. Because patient-level severity is not observed as a single validated outcome, this dissertation develops a Bayesian late-fusion supportability framework for constructing and predicting an ordered latent severity phenotype from clinical, genetic, and EEG-derived evidence. The primary target was constructed in a larger clinical cohort using age-5 symptom burden and learning cognition, then assigned to an aligned multimodal prediction cohort. Target-defining variables were excluded from supervised predictors, and models were evaluated using patient-exclusive cross-validation with training-fold preprocessing and fold-wise EEG PCA.

The primary …

Blood Flow Regulates Metabolism In Hematopoietic Development, Pamela L Wenzel

Faculty, Staff and Student Publications

Blood flow modifies oxygen availability and biomechanical forces within the vasculature of the embryo as the hematopoietic system develops. The aorta-gonad-mesonephros (AGM) envelops the largest artery in the body and is a critical site for the emergence of hematopoietic stem cells (HSCs). Herein, I discuss the role of hypoxia-inducible factors (HIFs) and force as determinants of metabolism and fate determination. To address the effects of blood flow on hematopoietic development, I employ mouse embryo models and biomimetic culture. Real-time cell metabolic analyses show that oxygen consumption rates (OCR) and extracellular acidification rates (ECAR) are altered by flow in cultures of …

The Effect Of Cybersecurity Breaches On Analysts’ Earnings Forecasts, Chih-Ying Chen, Beng Wee Goh, Kiat Bee Jimmy Lee, Na Li

Research Collection School Of Accountancy

We investigate the implications of cybersecurity breaches for financial analysts because they play an important role as information intermediaries in capital markets, and it is unknown whether analysts’ earnings forecasts are affected by cybersecurity breaches. Based on a sample of cybersecurity breaches from 2005 to 2018, we find that analysts’ earnings forecasts for firms with cybersecurity breaches are less accurate and more dispersed after a breach than for firms without such breaches. In cross-sectional analyses, we find that the adverse effects of cybersecurity breaches on analysts’ earnings forecasts are more pronounced for firms operating in more volatile business environments, for …

Does Auditor Quality Enhance Csr Disclosure?, Jimmy Lee, Chee Yeow Lim, Gerald J. Lobo, Yanping Xu

Research Collection School Of Accountancy

We investigate the relation between auditor quality and client firms’ corporate social responsibility (CSR) disclosure. Using an international sample of firms from 36 countries over the period 2009–2018 and a measure of the extent of CSR disclosure from Bloomberg, we find strong evidence that client firms with higher quality auditors provide more CSR disclosure. In cross-sectional analyses, we show that the relation between auditor quality and CSR disclosure is accentuated when the information environment is poorer and when the financial reporting environment and the legal institutions are weaker. Lastly, we document that firms with higher quality auditors also exhibit better …

Muzzle-To-Target Distance Determination Based On Lead (Pb) Concentration Of Gunshot Residue (Gsr) Using Icp-Oes, Abry Lloyd

Master of Science in Forensic Science Directed Research Projects

The determination of muzzle-to-target distance remains a significant challenge in forensic casework. Current approaches to gunshot residue (GSR) analysis rely primarily on colorimetric testing to indicate chemical components present and subjective interpretation, limiting specificity and contributing to ongoing scrutiny within the field. This study investigates a quantitative method for estimating shooting distance based on the concentration of lead present in GSR samples (w/w%) with the utilization of inductively coupled plasma optical emission spectrometry (ICP-OES). Test firings were conducted using caliber 22 Long Rifle, 9mm Luger, and 40 S&W semiautomatic handguns at defined distances to evaluate the relationship between lead concentration …

Differentiation Of Cell Populations In Saliva-Skin Mixtures Using Autofluorescence Profiling, Kara Fairfax

Master of Science in Forensic Science Directed Research Projects

While DNA profiling of sexual assault evidence can identify biological contributors, determining the tissue source of recovered profiles remains a significant challenge, particularly in cases of suspected oral assault involving mixtures of epithelial cells. The initial goal of this study was to identify non-genetic signatures for differentiating two types of epithelial cells relevant to oral assaults, saliva epithelial cells and epidermal skin cells. To develop tissue-specific signatures, reference cell populations from saliva and epidermal skin surfaces were collected from 20 donors and analyzed using full spectrum flow cytometry.

Results from single-source reference samples showed that saliva-derived particle populations exhibited higher …

Beyond Mean Length Of Utterance: Novel Measures For Characterizing The Spoken Language Of Autistic Children, Janine Mathee-Scott, Courtney E. Venker

Speech Pathology and Audiology Faculty Research and Publications

Purpose:

Mean length of utterance (MLU) is a common measure of expressive language complexity in young children, including autistic children. However, means, by nature, obscure some information about spread and variability in data. Thus, we aimed to examine a new approach to characterizing linguistic complexity in autistic children by investigating the validity of two novel measures—range of length of utterance (RLU), standard deviation of length of utterance (SDLU)—alongside established measures: MLU and total utterances (TU).

Method:

Participants were 40 autistic children (12 girls, 28 boys; M_age = 41.78 months). Children participated in 10-min, play-based language samples with their caregivers. …

Seeing The Invisible Load: Xr+ Multimodal Sensing For Cognitive Ergonomics In Industrial Training, Jessica M. Johnson, Andwele Grant

Virginia Digital Maritime Center (VDMC) Faculty Publications

Extended reality (XR) technologies are increasingly positioned as disruptive Industry 5.0 tools for human-centric industrial training and intelligent human–system integration. Coupled with multimodal sensing (eye tracking, EEG, HRV, GSR, and other physiological signals), XR environments promise to make otherwise invisible cognitive demands observable, especially for novice trainees entering complex industrial settings. Yet the evidence base is fragmented: (1) there is no quantitative synthesis of the cognitive ergonomics benefits of XR plus sensing; (2) little is known about which XR–sensor configurations yield the strongest effects; (3) prior reviews rarely focus on industrial and manufacturing tasks; (4) multimodal signals are used predominantly …

Research has found significantly higher rates of both substance use and obesity among individuals with SMI compared to population samples which in turn can lead to worsening health outcomes. Despite this, there is limited research on the co-occurrence of obesity, substance use, and SMI and how these conditions may interact to affect patient outcomes. In addition, there are many gaps in the research regarding the relationship between substance use and body weight, appetite and/or eating behaviors. This study conducted a secondary analysis of the NSDUH 2021 survey that characterized substance use and disorders among individuals who had severe psychopathology, examined …

Connectedness And Help-Seeking Among Veterans: Integrating The Andersen Behavioral Model And The Three-Step Theory Of Suicide, Samuel Ochinang

Theses and Dissertations

Veteran suicide rates remain higher than those of nonveterans, yet many veterans who die by suicide are not engaged in care prior to death. Veteran help-seeking research often focuses on healthcare utilization, overlooking informal sources of support and the decision-making processes that precede service use. Connectedness is a central protective factor in suicide theory but has received limited attention within help-seeking models. This study examined how connectedness influences veterans’ willingness to seek help. Guided by the Andersen Behavioral Model and the Three-Step Theory of Suicide, this secondary analysis used data from the Military Health and Well-Being Project. The analytic sample …

Family- And Cultural-Level Influences For Latine Adolescent Nicotine Use: A Qualitative Study Informing Prevention, Cindy M. Hernandez Castro

Theses and Dissertations

Early tobacco use among Latine adolescents represents a critical public health concern, with 23.8% reporting current use and exceeding rates among other racial/ethnic groups (Birdsey et al., 2023; Gaddy et al., 2022). This early initiation elevates risks for nicotine dependence and related morbidity in adulthood (Tsao et al., 2023). Guided by Structural Ecosystems Theory (Szapocznik & Coatsworth, 1999) and contemporary grounded theory analysis (Braun & Clarke, 2006; Charmaz, 2006; Noble & Mitchell, 2016), this study examined multilevel influences on nicotine-related attitudes among Latine youth, including: (1) familial factors (i.e., parental monitoring, caregiver-youth communication), (2) cultural dynamics (i.e., cultural values and …

Propensity Score Matching Accounting For Longitudinal Trends Before Baseline With Group-Based Trajectory Modeling, Dustin R. Bastaich

Theses and Dissertations

Propensity score matching is used in observational studies to balance baseline attributes between a treatment of interest and a control group. Propensity score matching typically relies on baseline variables, but longitudinal trends in patient characteristics can also influence treatment decisions and subsequent health outcomes. This dissertation extends standard approaches by explicitly incorporating longitudinal trajectories of key variables into the propensity score estimation process.

Trends in a longitudinal variable prior to baseline were characterized using group-based trajectory modeling. A two-step modeling approach was implemented where trajectory groups of a key variable were first estimated and then included as covariates in the …
