Acute Toxicity of Crude Oil Exposures to Early Life Stage Teleosts: Contribution of Impaired Renal Function and Select Environmental Factors

Description: Oil spills are well-known adverse anthropogenic events, as they can induce severe impacts on the environment and negative economic consequences. Still, much remains to be learned regarding the effects of crude oil exposure to aquatic organisms. The objectives of this dissertation were to fill some of those knowledge gaps by examining the effects of Deepwater Horizon (DWH) crude oil exposure on teleost kidney development and function. To this end, I analyzed how these effects translate into pote… more

Advanced Stochastic Signal Processing and Computational Methods: Theories and Applications

Description: Compressed sensing has been proposed as a computationally efficient method to estimate the finite-dimensional signals. The idea is to develop an undersampling operator that can sample the large but finite-dimensional sparse signals with a rate much below the required Nyquist rate. In other words, considering the sparsity level of the signal, the compressed sensing samples the signal with a rate proportional to the amount of information hidden in the signal. In this dissertation, first, we emplo… more

"Allegro de Concert," op. 46, by Frédéric Chopin: A Performance Guide

Description: Frédéric Chopin produced a remarkable body of piano works. Even though most of his works are essential repertoire in piano literature, some of them remain less familiar. One such significant work is the Allegro de Concert in A major, op. 46, which was apparently intended to be the first movement of a third piano concerto. Despite the praise the work has received, it is rarely heard, and references to performance are lacking in the scholarly literature. Some reasons include the substantial techn… more

Aristotle on Being Triggered: A Question on Moral Virtue

Description: I argue that Aristotle aids in understanding the tension between the political art and moral virtue through his examination of courage in The Nicomachean Ethics. The end of the political art is to habituate the city and citizens towards "the good." Aristotle examines five held opinions of non-courage, requiring that we reflect on our own vices. I describe how Aristotle prepares his readers for the task of examining the political art. I then view courage found in the citizen and spiritedness as … more

Il bel canto russo: Incorporating Principles from the Old Italian School of Singing to Russian Lyric Diction Utilizing the Songs of Mikhail Glinka (1804 -1857)

Description: Mikhail Glinka (1804-1857) is widely recognized as a founding father of Russian classical music, but in fact, his music represents a bridge: it establishes a distinctive Slavic sound built on the Italian roots of Glinka's musical inspiration. As a young man, Glinka traveled abroad, which included three years spent in Italy, where he gained extensive exposure to and familiarity with what modern scholarship refers to as the Old Italian School of Singing. This influence makes his songs an ideal in… more

Beyond the Hold: The Evolution of the Ship in African American Literature

Description: In the wake of a disturbing decades-long trend in both print and visual media—the appropriation of Black history and culture—another trend is observed in works of African American fiction: the reclamation of the appropriated imagery, in both neo-slave narratives and works of Afrofuturism. The image focused on specifically in this paper is that of the ship, which I argue serves at least two identifiable functions in Black fiction: first, to address the historical treatment of Africans and their … more

Bicultural Identity Integration and Psychological Wellness among Adult Children of Immigrants: Role of Cognitive Flexibility, Affect Regulation, and Adaptive Coping

Description: Guided by the framework of bicultural identity integration (BII), a conceptual model depicting the direct and indirect effects of BII, cognitive flexibility, affect regulation, and coping on psychological wellbeing indicators (i.e., life satisfaction, depression) of adult children of immigrants (ACI) in the U.S. was developed. It was hypothesized that greater BII would contribute to greater cognitive flexibility and affect regulation, which would be associated with more utilization of adaptive… more

Bifunctional Enamine‐Metal Lewis Acid Catalysis and α-Enaminones for Cyclization Reactions

Description: The use of enamines continues to be an important tool in organic syntheses as both a catalyst and reactant. The addition of metal catalysts coupled with enamine catalysis has generated many reactions that normally would not occur separately. However, catalysts' incompatibility is an issue that we wish to solve allowing new chemistry to occur without hindrance. The use of enamines has continued to be a well-studied area of organic chemistry, but the field is ripe for different types of enamines … more

Chemically Optimized Cu Etch Bath Systems for High-Density Interconnects and the FTIR Operando Exploration of the Nitrogen Reduction Reaction on a Vanadium Oxynitride Electrocatalyst

Description: Printed circuit board manufacturing involves subtractive copper (Cu) etching where fine features are developed with a specific spatial resolution and etch profile of the Cu interconnects. A UV-Vis ATR metrology, to characterize the chemical transitions, has been developed to monitor the state of the bath by an in-situ measurement. This method provides a direct correlation of the Cu etch bath and was able to predict a 35% lower etch rate that was not predicted by the three current monitoring met… more

Cognitive States while Mind Wandering and Associated Alterations in Time Perception

Description: Time perception is a fundamental aspect of consciousness related to mental health. One cognitive state related to time perception is mind wandering (MW), defined as having thoughts unrelated to the current task. Little research has directly assessed the relationship between these two constructs, despite the overlap in clinical significance and the shared importance of attention for healthy functioning. In the present study, I addressed this by having a sample of 40 adults in the United States c… more

Common Strategies for Regulating Emotions across the Hierarchical Taxonomy of Psychopathology (HiTOP) Model

Description: The hierarchical taxonomy of psychopathology (HiTOP) is a novel classification system that adopts both a dimensional and hierarchical approach to psychopathology to address shortcomings. However, the HiTOP framework is descriptive in nature and requires additional research to consider potential mechanisms for the onset and maintenance of psychopathology, such as cognitive-behavioral emotion regulation strategies. To redress this gap, a sample of 341 adults who endorsed ongoing mental health con… more
