A Spatial Scan Statistic For Group Testing Data, Vincent Onyame

Theses and Dissertations

Group testing involves pooling specimens from multiple individuals and offers an efficient means to surveil low-prevalence pathogens, but poses challenges for spatial cluster detection when only pooled results are observed. In this thesis, we develop a spatial scan statistic tailored to group-testing data with variable pool sizes. The statistic compares a null hypothesis of a homogeneous infection rate across all clusters to an alternative hypothesis that infection probabilities differ inside and outside a candidate cluster, with both models fitted by maximum likelihood estimation. We approximate the null distribution of the maximum likelihood ratio test via Monte Carlo simulation.

Understanding Verbal Irony: A Contrastive Analysis Of Personal And Informational Common Ground, Ruhan Çoban

Theses and Dissertations

This study investigates how representations of personal common ground (PCG; viz., close relationships vs. strangers) and informational common ground (ICG; viz., shared world knowledge) interact in shaping a reader’s comprehension of verbal irony in fictional narratives. While previous research has shown that greater familiarity among story characters enhances readers’ comprehension of ironic statements made by the characters (Gibbs, 2000; Kreuz et al., 1999; Kreuz & Link, 2001; Pexman & Zvaigzne, 2004), the interplay between representations of PCG and ICG remains understudied. In this study, we assumed that ICG takes precedence over PCG. Accordingly, we predicted that irony comprehension would be …

Assessing Health And Academic Disparities In The Deep South: The Enduring Impact Of Segregation And Redlining In Georgia, Bridget Hamilton

Theses and Dissertations

Background: Within the American South, marginalized Black populations continue to suffer from health disparities. A key resource that could aid in the prevention of health disparities such as teen pregnancy is the school nurse. School nurses are well positioned to assist in the development of independent health maintenance among student populations. However, school nurses remain understaffed and underfunded throughout most of the United States, which limits their effectiveness. It is possible that within southern states there are inequities in how school resources are allocated that have ties to segregation and redlining practices that systemically marginalized Black populations throughout the 1900s. …

Investigating The Role Of Metallothioneins In Fungal Iron Homeostasis, David Eap

Theses and Dissertations

The pathogenic fungi Aspergillus fumigatus requires metals to survive and infect humans, but metal overload can be detrimental. Metallothioneins (MTs) are small, cysteine-rich proteins that alleviate metal toxicity by binding excess metals (typically Zn or Cu) for storage or delivery. A recent report indicates that the Fe-S cluster binding glutaredoxin GrxD and the putative Cu-MT CmtA were interacting under high iron conditions in A. fumigatus. We hypothesize that this MT may have a role in binding iron or Fe-S clusters under iron overload conditions to prevent iron toxicity. We also aim to characterize this new MT by determining its …

Reduced Order Model-Based Framework For Microsecond Model Updating Of Two-Dimensional Structural Systems Using The Local Eigenvalue Modification Procedure, Emmanuel Abiodun Ogunniyi

Theses and Dissertations

Real-time model updating is crucial for active structures and electronic assemblies subjected to high-rate dynamic events. High-rate dynamic events refer to events that occur at high speeds and with rapid changes in the forces and energy involved. These events can include explosions, impacts, and crashes. These systems are characterized by a high dynamic response with a high rate (< 100 ms), high amplitude (> 100 gn), highly nonlinear, meaning that the response is not proportional to the applied force, and involve complex interactions between multiple objects or materials. A system exposed to high-rate dynamic environments is frequently prone to rapid plastic deformation, involving violent and …

Regression With Atypical Data: Measurement Error, Periodicity, And Non-Normality, Nicholas W. Woolsey

Theses and Dissertations

Regression is a ubiquitous and fundamental method that can be found in any ele- mentary statistics course. The simplicity and self evidently useful nature of linear regression beguiles a non-negligible portion of researchers into disrespecting assump- tions required by these models, namely in terms of accuracy of covariates and the underlying nature of the data. This disregard can at best lead to meaningless results and at worse cause significant misunderstandings in scientific pursuit.

In this dissertation we strive propose remedies to violations of specific assump- tions. Namely the assumptions that covariates are either observed without measure- ment error or they …
