Evaluating Tax Preparers’ Perception Of The Tax Cuts And Jobs Act (Tcja) Through The Lens Of The Tax Misperception Theory, Cari Valita Barnes

All Dissertations

The Tax Cuts and Jobs Act (TCJA) of 2017 represented one of the most extensive overhauls of the U.S. tax code in decades. While it is credited with reducing statutory tax burdens, the TCJA also introduced substantial complexity, which shaped tax preparers’ behavior and reshaped the tax preparation industry. Designed to stimulate economic growth through broad changes to both corporate and individual taxation, the TCJA’s impact on the profession cannot be understood without considering how preparers perceived the legislation. This study, therefore, evaluated the effects of the TCJA on tax preparers’ perceptions using the Tax Misperception Theory.

The Final Girl Without The Slasher: Final Girls, Gender, And Community In Psych, Cassidy Crosby

All Graduate Reports and Creative Projects, Fall 2023 to Present

This thesis focuses on the “Final Girl” trope, a hallmark of slasher films of the 1970s and 1980s, as it appears in detective procedural television show Psych to analyze what changes in the trope’s usage says about broader changes in American culture. I engage with two key episodes, “Scary Sherry: Bianca’s Toast” and “Tuesday the 17^th,” which contain the program’s most direct engagements with the Final Girl trope. Ultimately, I conclude that Psych rejects the hyperindividualism embedded in the Final Girl and some of the trope’s more binary gender norms, while also failing to interrogate other aspects of …

A Provable Semi-Infinite Programming Approach For Solving Dynamic Nash Games, Tyler C. Gardner

All Graduate Theses and Dissertations, Fall 2023 to Present

Many engineering problems must account for the non-cooperative decisions and actions of multiple players. These problems can be modeled within a game-theoretic framework. The approach herein is to model problems as Nash games, convert them to semi-infinite programs, and leverage provable semi-infinite algorithms to solve the original problem. A particular algorithm that leverages off-the-shelf solvers is used to solve four low-dimensional benchmark problems successfully. Two types of linear quadratic dynamic games are then investigated: ones where each player’s problem is convex and ones where at least one player’s problem is nonconvex. Within each type, variations based on information structure, communication …

Aquatic Habitat Representation For Robust Water Resources Management And Fish Conservation Decision-Making, Gregory C. Goodrum

All Graduate Theses and Dissertations, Fall 2023 to Present

We rely on rivers to provide water supply, flood control, and hydroelectricity for people and to sustain aquatic ecosystems. The development of dams and reservoirs to provide water for people did not consider environmental impacts to rivers, leading to widespread decline of freshwater species and habitat. Improving environmental outcomes of water management is needed to protect and restore aquatic ecosystems. However, rivers are complex and variable, making them difficult to represent as objectives for water management. This dissertation explores approaches to improve aquatic habitat representation and environmental objectives for water resources management and river conservation and restoration.
