Modified Geometries, Clifford Algebras And Graphs: Their Impact On Discreteness, Locality And Symmetr, Roman Sverdlov

Mathematics & Statistics ETDs

In this dissertation I will explore the question whether various entities commonly used in quantum field theory can be “constructed". In particular, can spacetime be “constructed" out of building blocks, and can Berezin integral be “constructed" in terms of Riemann integrals.

As far as “constructing" spacetime out of building blocks, it has been attempted by multiple scientific communities and various models were proposed. But the common downfall is they break the principles of relativity. I will explore the ways of doing so in such a way that principles of relativity are respected. One of my approaches is to replace points …

Then, mainstream MFRL algorithms are introduced with an explanation of how MFRL can be integrated into the existing control framework. Next, the application guideline of MFRL is summarized with a discussion of …

Minimal Positional Substring Cover Is A Haplotype Threading Alternative To Li And Stephens Model, Ahsan Sanaullah, Degui Zhi, Shaojie Zhang

Faculty, Staff and Student Publications

The Li and Stephens (LS) hidden Markov model (HMM) models the process of reconstructing a haplotype as a mosaic copy of haplotypes in a reference panel. For small panels, the probabilistic parameterization of LS enables modeling the uncertainties of such mosaics. However, LS becomes inefficient when sample size is large, because of its linear time complexity. Recently the PBWT, an efficient data structure capturing the local haplotype matching among haplotypes, was proposed to offer a fast method for giving some optimal solution (Viterbi) to the LS HMM. Previously, we introduced the minimal positional substring cover (MPSC) problem as an alternative …

Am I Committed Or Conflicted? Examining Implications Of Self-Concept Structure For Self-Regulation, Well-Being, And Performance, Nicholas Aaron Moon

Theses and Dissertations

Although research on self-concept is extensive, few studies have examined the relationship between specific aspects of self-concept structure (e.g., self-concept clarity) and self-regulation constructs (e.g., goal commitment). In addition, research has linked aspects of self-concept structure with well-being outcomes, but less is known about the mechanisms involved in these relationships. This research addresses these two issues by examining self-concept structure (self-concept clarity and self-concept differentiation) as antecedents of key self-regulatory mechanisms (goal commitment and goal conflict) and how these linkages may help explain connections between self-concept structure and well-being and performance. More specifically, two studies examined these relationships, with Study …

An Exploratory Study Of The Impact Of Quality Management Practices On Data Integrity Fda-483 Observations Received By Pharmaceutical Manufacturers In Florida, Sarah Mary Christie

Theses and Dissertations

Quality management systems and regulatory compliance have been studied in academic and practitioner settings (Andersson et al., 2006; Beattie & Sohal, 1999; Berrouiguet, 2013; McDowall & Ratcliff, 2016; Unger, 2019; Wechsler, 2019). While research has been performed on both topics independently, there has not been a definitive analysis of the relationship between quality management practices and regulatory compliance, especially in an FDA-regulated manufacturing environment. This research study attempts to link quality management practices and regulatory compliance and provides valuable insights for working managers on the practitioner level.

Evaluating The Use And Performance Of Marine Protected Areas To Conserve Reef Fish Biodiversity In The Caribbean, Mathias Tjarko Cramer

Theses and Dissertations

Reef fishes are an integral part of life in the Caribbean, fulfilling essential roles in their native marine ecosystems and the many human communities that neighbor them. Perhaps most directly to humans, reef fishes and their fisheries are an essential source of dietary protein, and further support local human communities through employment opportunities. More indirectly, reef fishes fulfill numerous ecological roles that help maintain their native reef ecosystems, which, in turn, confer benefits to humans. For example, a recent analysis estimated that every square kilometer of coral reef generates an average annual income of $473,000 (USD), which would represent 23 …

Increasing Cheerleader Safety Through The Observer Effect, Madison Elizabeth Duke

Theses and Dissertations

Cheerleading has a high rate of serious injuries, but the safety of cheerleaders has seldom been researched. Behavior analytic research has never investigated cheerleading and has rarely focused on improving the safety of athletes. The present study examined scored observations, a common intervention in the behavior-based safety literature, as a method to increase the safety of cheerleaders completing basic movements. This has previously been shown to produce the observer effect, wherein an observer’s safe behavior is increased after observing and scoring the behavior of another performer. Scored observations alone increased basic cheerleading movements to a mastery criteria for one of …

The Influence Of Benevolent Sexism In Teams: A Team Composition And Attribute Alignment Approach, Catherine Warren

Theses and Dissertations

Researchers have long struggled with harnessing the benefits accompanying diversity, such as increased knowledge sharing and the diverse expertise of individuals. One barrier that hinders taking advantage of such diversity is discrimination, such as sexism. Indeed, evidence has indicated that subtle sexism, compared to overt sexism, has a similar magnitude in impacting workplace outcomes. Additionally, teams are ubiquitous in organizations with the increase in complex taskwork, requiring a set of individuals to collaborate and produce outcomes greater than each individual effort. Accordingly, teamwork requires close, interdependent relationships for optimal performance. The purpose of this study was to assess a prevalent …

An Empirical Investigation Of The Behavior And Cognition Of Engineering Designers While Describing Domains Of Design Problems, John Kochenberger

Theses and Dissertations

This thesis presents a protocol study that examines the behavioral and cognitive patterns in human designers when they describe a problem domain of engineering interest through constructing concept maps. Understanding various design problem domains usually comes in design projects before the start of the formal design process and is crucial for discovering the pain points of given scenarios and identifying opportunities for creating value to improve them. Thus, this activity relies on the entrepreneurial aspects of engineering design that leads to identifying the right design problem to solve. While concept maps have been used to examine various research questions in …

A feedback intervention was implemented for participants who did not reach mastery with just exposure to the teaching interactions procedure alone. Maintenance probes were conducted after mastery was reached. The results showed that for two of …

Relations Between Heart Rate And Precursors To Aggression With Children With Autism Spectrum Disorder, Emily Wynn Dowling

Theses and Dissertations

Aggression is a commonly reported problem behavior for individuals diagnosed with autism spectrum disorder. When assessing and treating aggression, there are risks of injury to the client and staff when the problem behavior is aggression. Investigating physiological arousal states of clients may be fruitful if this physiological measure can be used to predict occurrences of problem behavior, such as aggression. Previous research has shown varied results when investigating the relations between heart rate and problem behaviors. For some individuals, heart rate increased preceding problem behavior and for others heart rate decreased (Barrera et al., 2007). The temporal relation between heart …

Identifying low clouds is especially useful with respect to aviation, particularly in regions of complex topography prone to visibility-related hazards such as haze or fog. To address this issue, a threshold-based semi-automated algorithm was developed and tested to determine whether or not an image is obscured by fog or haze. Images were obtained from a ground-based camera network in Southern California, the …

Fast Inference Of Genetic Recombination Rates In Biobank Scale Data, Ardalan Naseri, William Yue, Shaojie Zhang, Degui Zhi

Faculty, Staff and Student Publications

Although rates of recombination events across the genome (genetic maps) are fundamental to genetic research, the majority of current studies only use one standard map. There is evidence suggesting population differences in genetic maps, and thus estimating population-specific maps, are of interest. Although the recent availability of biobank-scale data offers such opportunities, current methods are not efficient at leveraging very large sample sizes. The most accurate methods are still linkage disequilibrium (LD)-based methods that are only tractable for a few hundred samples. In this work, we propose a fast and memory-efficient method for estimating genetic maps from population genotyping data. …
