Ceo, Cfo, And Audit Partner Gender, And Accounting Conservatism, Ceara Hintz

Electronic Theses and Dissertations

I examine the association between CEO, CFO, and audit partner gender and accounting conservatism using a unique sample that encompasses hand-collected data. While accounting conservatism reflects less risky accounting choices, risk aversion theory indicates that females are more risk averse than males. I apply risk aversion theory to accounting conservatism and investigate two research questions: (i) Does the CEO or CFO and audit partner gender influence accounting conservatism? (ii) Does a female audit partner influence the relationship between a male CEO or CFO and accounting conservatism? Using skewness as a proxy of accounting conservatism, I test three hypotheses. The results …

Neural And Behavioral Evolution In An Eavesdropper With A Rapidly Evolving Host, Aaron W. Wikle

Electronic Theses and Dissertations

The diversification of animal communication systems is driven by many interacting factors. Unintended receivers play an important part in this process, yet little is known about their role in signal evolution. Flies of the genus Ormia are parasitoids of crickets and rely on acoustic cues to locate hosts. In Hawaii, selection imposed by Ormia ochracea has led to recent and rapid diversification in the songs of their host. Here, we compare neural and behavioral responses of Hawaiian flies to those of an ancestral population to understand the role of parasitoid sensory and behavioral variation in the evolution of host songs. …

Surviving The Serenade: How Conflicting Natural And Sexual Selection Drove Rapid Diversification Of Mating Signals In An Insect, James H. Gallagher

Electronic Theses and Dissertations

Understanding how the early stages of sexual signal diversification proceed is of critical importance because the nature of these microevolutionary dynamics can directly shape species trajectories and macroevolutionary patterns. Unfortunately, studying signal diversification is challenging because signals involve complex interactions between behavioral, morphological, and physiological components, many of which can only be measured in real time. Here we had the opportunity to directly study this process with the recent increase in sexual signal variation in Hawaiian populations of the Pacific field cricket (Teleogryllus oceanicus). In Hawaii, male song attracts both female crickets and a deadly acoustically orienting parasitoid …

Power System Dynamic Control And Performance Improvement Based On Reinforcement Learning, Wei Gao

Electronic Theses and Dissertations

This dissertation investigates the feasibility and effectiveness of using Reinforcement Learning (RL) techniques for power system dynamic control, particularly voltage and frequency control. The conventional control strategies used in power systems are complex and time-consuming due to the complicated high-order nonlinearities of the system. RL, which is a type of neural network-based technique, has shown promise in solving these complex problems by fitting any nonlinear system with the proper network structure.

The proposed RL algorithm, called Guided Surrogate Gradient-based Evolution Strategy (GSES) determines the weights of the policy (which generates the action for our control reference signal) without back-propagation process …

Queer Is Here, Hopefully To Stay: The Incorporation And Reception Of Lgbtq+ History At The History Colorado Center, Madeline Ohaus
