Evaluation Of Brook Trout (Salvelinus Fontinalis) Thermal Tolerance And Projected Climate Change Effects On Headwater Brook Trout Population Persistence, Cory Bauerlien Jan 2026

Evaluation Of Brook Trout (Salvelinus Fontinalis) Thermal Tolerance And Projected Climate Change Effects On Headwater Brook Trout Population Persistence, Cory Bauerlien

Graduate Theses, Dissertations, and Problem Reports (ETD)

Climate change has been identified as one of the greatest threats to global biota in recorded human history. Consequences are expected to be more pronounced in ectotherms because most of their physiology is controlled by external temperature conditions. Predicting how ectotherms may respond to increasing global temperatures necessitates information about thermal limits of thermal sensitive species and how increasing temperatures may affect individual and population-level fitness. Therefore, the objectives of this research were aimed at gaining a better understanding of the mechanisms that underpin thermal tolerance limits of fish and how those mechanisms may affect fitness and population persistence under …


Treatment Of Birdsong In Selected Works For Solo Piano, Madeline Hoover Jan 2026

Treatment Of Birdsong In Selected Works For Solo Piano, Madeline Hoover

Graduate Theses, Dissertations, and Problem Reports (ETD)

Birdsong-inspired music makes up a small but important part of the classical piano repertoire. This paper reviews birdsong in classical music since the seventeenth century, exploring different techniques for mimicking birdsong and the unique strengths of the piano as an instrument for purveying bird music. In the Baroque and Classical eras, the cuckoo song was sampled often because of its simplicity. Later, composers’ attention turned toward more complicated songs, like that of the hermit thrush. Interest in more complex songs led to experimentation in notation and a push for more accurate transcriptions. In the 20th century, composers included recordings of …

Jazz And Classical Form In Selected Movements Of Nikolai Kapustin's Eight Concert Etudes Opus 40, Hsiaofen Lin

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research focuses on three etudes from Kapustin’s Eight Concert Etudes, Op. 40, offering analyses for “Prelude,” “Reverie,” and “Toccatina,” The analysis explores several interrelated issues: the extent to which jazz-derived formal structures may be discerned in Kapustin’s piano works beyond traditional classical models; the ways in which jazz structural frameworks interact with forms such as sonata, ternary, and through-composed designs; and the degree to which jazz formal procedures influence sectional organization, phrase structure, and large-scale form. A further concern is whether Kapustin’s use of jazz form serves merely as a stylistic reference or operates as a structurally determinative …

Be A Man: Hypermasculinity And Hostile Attribution Bias As Predictors Of Violence, Kaley Nicole Potter

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, violence has risen to record-high numbers in communities and correctional facilities, with men perpetrating the vast majority of violent crimes. Hypermasculine values (e.g., power, aggression, and domination) have been linked to aggressive and violent behavior. Hostile attribution bias, which leads individuals to attribute hostile intent to neutral or ambiguous stimuli, has also been linked to aggression.

The current study used structural equation modeling (SEM) to examine hypermasculinity and hostile attribution bias as predictors of proclivity for violence, comprised of aggression and historical violence. The model was iteratively modified to assess changes in model fit and constructs. Male …

A Digital Audio Workstation-Based Analytical Framework For Contemporary Acoustic Music: Modeling Selected Excerpts By Viet Cuong, Robert Daniel Traugh

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Digital Audio Workstation (DAW) has made sound recording, manipulation, MIDI sequencing, and digital live performance accessible to nearly anyone with a computer and an interest in digital music-making. A DAW’s functionality is modeled on decades of development in analog modular electronic instrument design and sound recording techniques. Theorist and composer Jonathan D. Kramer, through his work in the 1980’s, referred to the invention of sound recording as a catalyst of a temporal discontinuity experienced by Western-trained musicians. Since that time, these same sound recording techniques have become increasingly prevalent in modern society. This document proposes a DAW-based analytical framework …


Statistical Analysis Of Evidence In Criminal Cases, Giuliana Leon Carrillo Jan 2026

Statistical Analysis Of Evidence In Criminal Cases, Giuliana Leon Carrillo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ideally, the evaluation of relevant forensic evidence must corroborate the hypotheses that the prosecution and/or the defense holds regarding the commitment of a crime. Therefore, optimal forensic evidence would be the one that can be found all the time under the same circumstances, and cannot be found otherwise, making the forensic scientist able to evaluate this evidence given the hypotheses provided. Nevertheless, this is hard to find, as ideal evidence being only a concept.

In this project, the probabilistic interpretation of relevant forensic evidence investigated in criminal cases with the aid of Wigmore charts and Bayesian networks was proposed. Using …

Three Essays On Option Markets, Fangzheng Ou Jan 2026

Three Essays On Option Markets, Fangzheng Ou

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation includes three essays examining index option and stock option markets. The first essay investigates the pricing kernel puzzle by examining S&P 500 index option returns and empirical pricing kernels across expiration dates ranging from one month to one year. We document that at short maturities, out-of-the-money call option returns are negative and decrease with the strike price, while at long maturities, at least some are positive and increase with the strike price. Empirical pricing kernels predominantly exhibit a W-shape at short maturities, with this pattern becoming less pronounced and evolving toward a monotonically decreasing curve at longer maturities. …


White Lies Of Time: Temporal Racialization In 19th-20th Century American Literature, Yu Uchida Jan 2026

White Lies Of Time: Temporal Racialization In 19th-20th Century American Literature, Yu Uchida

Graduate Theses, Dissertations, and Problem Reports (ETD)

By examining mid-nineteenth to mid-twentieth century American literary texts, this dissertation project aims to theorize the ways in which whiteness relies on conceptualizations of time to hegemonize non-white subjects and prescribe their historical representations. Because whiteness is dynamic in its emergence and effects and ubiquitous in sociopolitical and cultural realms, this dissertation holistically turns to white, Black, and Indigenous writers to delineate how whiteness functions throughout the period and how racialized subjects negotiate it. Portraying the nation’s history as lived experience rather than objectified knowledge, the racialized authors I examine undermine the concept of linear progressive time that subtends structural …

Community Resilience Drives Change, Andrew Thomas Solt Jan 2026

Community Resilience Drives Change, Andrew Thomas Solt

Graduate Theses, Dissertations, and Problem Reports (ETD)

The opioid crisis has impacted many Americans. From 1999 to 2023, approximately 800,000 people have died due to opioid overdose (CDC, 2025). What began as overprescriptions of painkillers has quickly evolved into a complex social health issue that is now further worsened by stronger synthetic drugs like fentanyl. Fentanyl and fentanyl analogs (synthetic opioids that are very similar chemically to fentanyl) are often found in illegal drug supplies and in counterfeit pills (CDC, 2025). Thus, individuals who might have been initially overprescribed painkillers might now be pushed towards illegally produced drugs that are significantly more potent than what they were …

Studies On The Depth Formula And On Reducing Dimensions, Brian Mccourt Laverty Jan 2026

Studies On The Depth Formula And On Reducing Dimensions, Brian Mccourt Laverty

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation presents the author’s recent research, conducted under the supervision of Professor Olgur Celikbas, and based on two articles—one published and one in progress. These works develop two closely related research directions in commutative algebra. Together, they contribute to the subject by addressing aspects of existing conjectures, establishing new results, and introducing methods for studying homological invariants.

The first research direction concerns the depth formula, namely the equality \[ \depth_R(M)+\depth_R(N)=\depth(R)+\depth_R(M\otimes_RN) \] where $M$ and $N$ are finitely generated $R$-modules. A classical result of Auslander \cite{Aus} shows that the depth formula holds provided that either $M$ or $N$ has finite …


Machine Learning-Based Prediction Of Heavy-Duty Diesel Engine Emissions And Comparative Analysis Against Statistical Models, Abdullah Ahmad Khan Jan 2026

Machine Learning-Based Prediction Of Heavy-Duty Diesel Engine Emissions And Comparative Analysis Against Statistical Models, Abdullah Ahmad Khan

Graduate Theses, Dissertations, and Problem Reports (ETD)

The increasing stringency of emissions regulations for heavy-duty (HD) diesel engines necessitates the development of accurate, efficient, and general predictive models for engine-out emissions under steady-state operating conditions. Traditional statistical approaches, while computationally efficient, often fail to capture the inherent nonlinear relationships between the engine operating parameters and emissions formation. In contrast, machine learning (ML) techniques offer a promising alternative by learning the complex patterns directly from experimental data. The present thesis summarizes a comprehensive study on the prediction of steady-state, HD diesel engine emissions using ML models, along with a comparative analysis against conventional statistical modeling approaches.

A high-quality …
