Bayesian Mediation Analyses For Zero-Inflated Data, Jinhong Cui Sep 2025

Bayesian Mediation Analyses For Zero-Inflated Data, Jinhong Cui

All ETDs from UAB

Mediation analysis is a fundamental tool in causal inference, enabling researchers to disentangle the pathways through which an exposure affects an outcome via intermediate variables (mediators). It has been widely applied in social sciences, psychology, and healthcare-related studies. Traditionally, mediation analysis has been conducted within the linear structural equation modeling (LSEM) framework. However, recent advances have shifted attention toward the counterfactual framework due to its flexibility in defining causal effects and its capacity to accommodate non-linear relationships, parametric and non-parametric models. Building on this foundation, methodological developments in mediation analysis have expanded to address more complex data structures, such as …

Parenting And Parental Well-Being As Risk And Resilience Factors For Mental Well-Being In Adolescents With And Without Neurodevelopmental Disorders, Wanqin Yu Sep 2025

Parenting And Parental Well-Being As Risk And Resilience Factors For Mental Well-Being In Adolescents With And Without Neurodevelopmental Disorders, Wanqin Yu

All ETDs from UAB

Parenting practices and caregiver well-being are widely recognized as key determinants of adolescent mental health. However, few studies have examined how these factors operate in the context of neurodevelopmental disorders (NDDs), particularly through a risk and resilience framework. This study investigated how positive and negative parenting practices, caregiver well-being, and parenting stress relate to adolescents’ emotional well-being and internalizing problems. It also explored whether these variables differed between adolescents with and without NDDs. Participants included 105 adolescents aged 11–14 years (61.9% female; 52.4% diagnosed with an NDD) and their caregivers, drawn from a larger study on adolescent socio-emotional competencies. Caregivers …

Calibrating A Holling-Tanner Model With Applications To S&P500 Forecasting, Jonathon Knowles

All ETDs from UAB

The primary goal of this thesis is to improve upon existing dynamical system models in economics. Existing models utilizing Lotka-Volterra dynamics display a tendency to suffer from unrealistic forecasts dominated by exponential growth and decay. Additionally, current inverse methods are only applicable in differential equation systems with linear coefficients. In this body of work, we propose novel methods for handling these challenges.

The Longitudinal Associations Between The Longitudinal Associations Between Parent Involvement And Academic Achievement In Elementary School Involvement And Academic Achievement In Elementary School, Makayla Elizabeth Warnecke Sep 2025

The Longitudinal Associations Between The Longitudinal Associations Between Parent Involvement And Academic Achievement In Elementary School Involvement And Academic Achievement In Elementary School, Makayla Elizabeth Warnecke

All ETDs from UAB

Parent involvement has been positively linked to children’s academic outcomes (e.g., Chavkin, 1993; Eccles & Harold, 1993; Epstein, 1989, 1994; Hess & Holloway, 1984; Hobbs et al, 1984; U.S Department of Education, 1994). These outcomes include higher achievement test scores (Keith et al., 1986), better grades (NCES, 1985), and increased rates of secondary school completion (Chavkin & Williams, 1993; Delgado-Gaitan, 1988, 1992; Epstein, 1986, 1995; Angiano, 2004). However, gaps remain in the current state of research when investigating longterm implications. In a recent meta-analysis, researchers stated the lack of analyses using a longitudinal cross-lagged design as a future direction (Barger …

Structural Basis For Promoter Recognition By Pseudomonas Phage Dev Virion Associated Rna Polymerase, Brittney Bird Sep 2025

Structural Basis For Promoter Recognition By Pseudomonas Phage Dev Virion Associated Rna Polymerase, Brittney Bird

All ETDs from UAB

Bacteriophage DEV, a member of the Schitoviridae family, encodes a large virion-associated RNA polymerase (vRNAP) and shows significant potential for use in phage therapy. However, many aspects of DEV’s biology remain poorly understood, especially how it regulates transcription once inside the host. Recent work in our lab suggests that gene product 71 (gp71) functions as a DNA-dependent vRNAP. Analogous to the vRNAP of coliphage N4, gp71 likely initiates transcription by recognizing single-stranded DNA templates that contain early gene hairpin promoters. Based on this, my working hypothesis is that specific interactions between gp71 and the DEV early promoters PE1 and PE5 …

Effect Of Fiber Structure Heterogeneity On The Estimation Of Material Parameters For Cardiac Scar Tissue Mechanics, Desmond Maximilian Flanagan Sep 2025

Effect Of Fiber Structure Heterogeneity On The Estimation Of Material Parameters For Cardiac Scar Tissue Mechanics, Desmond Maximilian Flanagan

All ETDs from UAB

Over one million Americans suffer from myocardial infarction (MI) per year. After MI, the heart muscle is replaced by scar, whose mechanical properties play a critical role in outcomes for surviving patients. Previously, Caggiano et al. induced MI in rats, and ex-tracted the scar tissue samples for microscopy and mechanical testing. Building on this, we investigate the effect of incorporating microscopy-derived fiber heterogeneity on the estimation of stress and material parameters. We studied the effect of fiber orientation heterogeneity on the mechanical characteriza-tion of scar tissues using finite element models (FEM) that replicated biaxial tests. We used three constitutive models—Mooney-Rivlin, …

Mcl1 And Hexokinase 2 Form A Glucose Metabolic Regulatory Axis, Robert Lee Sep 2025

Mcl1 And Hexokinase 2 Form A Glucose Metabolic Regulatory Axis, Robert Lee

All ETDs from UAB

Hexokinase 2 (HK2) initiates glucose metabolism by catalyzing the conversion of glucose to glucose-6-phosphate providing the starting substrate for a vast array of metabolic pathways such as glycolysis, pentose phosphate pathway (PPP), amino acid biosynthesis and others. While HK2’s metabolic role in normal physiologic function (such as in cardiomyocytes) and cancers (through driving the Warburg Effect) are well established, there is emerging evidence that supports HK2 is also a critical mediator of protein-protein interactions that regulate cell survival. Through comprehensive review, we explore how HK2 contributes to cell survival through metabolic and protein scaffolding roles. We also investigate a novel …

Lineage-Associated Zinc Metalloprotease B And Its Impact On Cardiac Damage Elicited During Invasive Pneumococcal Disease, Jennifer Nichelle Luck Sep 2025

Lineage-Associated Zinc Metalloprotease B And Its Impact On Cardiac Damage Elicited During Invasive Pneumococcal Disease, Jennifer Nichelle Luck

All ETDs from UAB

During invasive disease, certain strains of Streptococcus pneumoniae (Spn) can invade the myocardium, damaging cardiomyocytes and predisposing patients to life-threatening cardiac complications. To identify genetic loci involved in pneumococcal cardio-virulence, we performed a bacterial genome-wide association study using 825 genomes corresponding to 17 distinct Spn lineages associated with varying rates of cardiac complications during hospitalization for pneumonia. This led to the identification of an allele of zmpB, the gene encoding Zinc metalloprotease B (ZmpB). Infection of mice with a ZmpB deficient mutant, i.e., TIGR4ΔzmpB, found that ZmpB was required to form foci of infection in the heart, i.e., cardiac microlesions. …

Modeling The Basal Ganglia Network Using Leaky Integrate-And-Fire Neurons To Explore Its Role In Facilitating Purposive Saccades, Saarth Anjali Chitale Sep 2025

Modeling The Basal Ganglia Network Using Leaky Integrate-And-Fire Neurons To Explore Its Role In Facilitating Purposive Saccades, Saarth Anjali Chitale

All ETDs from UAB

Saccadic eye movements provide a well-defined behavioral readout for investigating how the basal ganglia (BG) contribute to action selection. While saccades are controlled by multiple brain regions, including direct excitatory inputs from various cortices, the BG exerts a key inhibitory influence. Decades of experimental work using saccadic behavioral paradigms in non-human primates have yielded important insights into the activity of BG populations. These include the caudate nucleus, subthalamic nucleus, globus pallidus externus, and substantia nigra pars reticulata, as well as dopaminergic afferents from the substantia nigra pars compacta and efferent projections to the superior colliculus, which controls eye movements. Despite …

From Model To Behavior: Methodological Challenges In Using Fuzzy Cognitive Maps To Represent Mental Models, Catherine Elizabeth Moore Sep 2025

From Model To Behavior: Methodological Challenges In Using Fuzzy Cognitive Maps To Represent Mental Models, Catherine Elizabeth Moore

Dissertations and Theses

This dissertation examines the use of Fuzzy cognitive maps (FCMs) as representations of mental models and how these representations connect to individual behavior. Fuzzy cognitive maps (FCMs) are semi-quantitative models that encode cause-and-effect structures as directed graphs. They are frequently used to represent individuals' knowledge structures/mental models and should in theory correlate to actions and decisions of individuals; however, this correlation has yet to be explored in a systematic manner. This dissertation represents the first step in experimental research on the connection between FCMs and individual behavior. It examines two theories of how humans use mental models, one based on …

Mechanistic Rationale For Toxic Aerosol Formation From Vaping And Dabbing With A Focus On Ketene Formation From Semi-Synthetic Cannabinoids, Kaelas Ryan Munger Sep 2025

Mechanistic Rationale For Toxic Aerosol Formation From Vaping And Dabbing With A Focus On Ketene Formation From Semi-Synthetic Cannabinoids, Kaelas Ryan Munger

Dissertations and Theses

Cannabis vaping is a relatively new route of administration that is increasingly common among youth and young adults. Cannabis vaping has been associated with cases of acute lung injury, especially among youth, and most often involves the heating and aerosolization of high-potency products having cannabinoid concentrations of ~ 50 % - 98 % w/w. Proponents argue that vaping is safer than smoking due to the characteristically lower temperatures and fewer plant materials. However, the extreme cannabinoid concentrations, along with non-natural formulations having undisclosed additives, require studies of the health effects of these products. Despite the popularity of cannabis concentrate vaping, …

Autonomous Versus Collaborative Online Professional Development: Discovering The Differences In Teacher Learning And Perceptions, Michelle Thomas, Heather Tellier, Jennifer Urbach, Corey Pierce Ph.D., Holly Baker-Hill Sep 2025

Autonomous Versus Collaborative Online Professional Development: Discovering The Differences In Teacher Learning And Perceptions, Michelle Thomas, Heather Tellier, Jennifer Urbach, Corey Pierce Ph.D., Holly Baker-Hill

Journal of Educational Research and Innovation

Online, asynchronous professional development (PD) offers flexibility for learners, yet what is the most effective way to provide online PD? While current research suggests online platforms can be effective for learning, there is a lack of studies examining differences between fully autonomous, asynchronous modules and those that are asynchronous but still collaborative. This mixed-method study examined the learning differences and perceptions between two cohorts of special education teachers as they went through an eight-unit online course on dyslexia. One cohort received an autonomous platform without interaction among the students or instructor. The other cohort received the same content, but online …

Self-Organization In Metal Plasticity: An Ilg Update †, Avraam Konstantinidis, Konstantinos Spiliotis, Amit Chattopadhyay, Elais C. Aifantis

Michigan Tech Publications

In a 1987 article of the last author dedicated to the memory of a pioneer of classical plasticity Aris Philips of Yale, the last author outlined three examples of self-organization during plastic deformation in metals: persistent slip bands (PSBs), shear bands (SBs) and Portevin Le Chatelier (PLC) bands. All three have been observed and analyzed experimentally for a long time, but there was no theory to capture their spatial characteristics and evolution in the process of deformation. By introducing the Laplacian of dislocation density and strain in the standard constitutive equations used for these phenomena, corresponding mathematical models and nonlinear …

Gw250114: Testing Hawking’S Area Law And The Kerr Nature Of Black Holes, The Ligo Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration

Department of Physics and Astronomy Faculty Scholarship and Creative Works

The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence of two black holes with near-equal masses 𝑚1=33.6+1.2−0.8⁢𝑀⊙ and 𝑚2=32.2+0.8−1.3⁢𝑀⊙, and small spins 𝜒1,2≤0.26 (90% credibility) and negligible eccentricity 𝑒⁢≤0.03. Postmerger data excluding the peak region are consistent with the dominant quadrupolar (ℓ=|𝑚|=2) mode of a Kerr black hole and its first overtone. We constrain the modes’ frequencies to ±30% of the Kerr spectrum, providing a test of the remnant’s Kerr nature. We also examine Hawking’s area law, also known as the second law …

Paleoseismic Evidence Of Directivity For The 1976 Mw 7.5 Motagua Earthquake, Guatemala, Jonathan Obrist-Farner, Jeremy Maurer, Derek Gibson, Trenton Mcenaney, Andreas Eckert, William F. Kenney, Jeffrey Beeson, Nigel Wattrus, Quin Stangeland, Fatima Reyes

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

On 4 February 1976, a Mw 7.5 earthquake along the Motagua fault, Guatemala, ruptured ∼230 km of the North American and Caribbean plate boundary. Today, the plate boundary remains poorly monitored, and the 1976 earthquake is still not fully understood. Here, we present seismic reflection profiles and radiometrically dated sediment core data from six lakes around the Motagua fault, together with reports of destruction and a quasi-dynamic rupture model, which show that the 1976 earthquake experienced strong directivity that impacted the distribution of shaking. The earthquake left behind a detailed record of event deposits (EDs) in five of the six …
