Navigating Uncertainty In Tax Strategy Surrounding The Tax Cuts And Jobs Act Sunset, Tate Smith

Undergraduate Honors Capstone Projects

Throughout history, taxpayers have relied on tax strategies to reduce the proportion of income that is deemed taxable by the government. Today's tax environment is no exception, and with the changes surrounding the Tax Cuts and Jobs Act (TCJA) Sunset, taxpayers need to prepare their tax plans. In 2025, much of the current tax legislation for individual taxpayers will potentially revert to the pre-TCJA legislation. Preparing a strategy during this time period will be difficult because when the current legislation sunsets in 2025 many of the legislation changes will depend on which political party controls the presidency.

The Function Of Humility In St. Teresa Of Avila's Autobiography: A Literature Review, Jennifer Sanchez

All Graduate Reports and Creative Projects, Fall 2023 to Present

In the Carmelite nun St. Teresa of Ávila’s (1515-1582) autobiography, The Life of Saint Teresa of Ávila by Herself (1588), the author repeatedly asserts her unworthiness. Contemporary scholarship has explored the function of Teresa’s rhetoric of humility in this text. Scholars from the 1990s have largely argued that Teresa’s humility is a carefully crafted, defensive method to meet the demands of the patriarchal culture in which she wrote. Twenty-first-century scholars take a (slightly) different approach. To them, Teresa’s humility is not solely rhetorical; they suggest that Teresa’s humility is also a consequence and tool of her spiritual journey. In this …

Public Cyberattack Attribution And Domestic Political Considerations: An Analysis Of State Decision Making, Ella M. Devey

All Graduate Theses and Dissertations, Fall 2023 to Present

When a country is targeted with a cyberattack, what compels its government to publicly attribute the perpetrators of the attack rather than keep their attribution private? Cyberattacks are an increasingly utilized weapon of international conflict by governments, groups, and individuals. Following a cyberattack, the target of the attack may investigate the origin of the attack and may choose to share their findings with the public; alternatively, they may choose not to publicly share their findings.

While we know that forensic capabilities and international political factors contribute to the decision of governments to make public cyberattack attribution, domestic political circumstances may …

Evaluating 1d And 2d Small-Strain Ground Response Analyses At The I-15 Downhole Array Using Recorded Aftershocks From The M5.7 2020 Magna, Utah Earthquake, Tyler S. Jackson

All Graduate Theses and Dissertations, Fall 2023 to Present

As earthquake waves exit rock and travel up through softer subsurface strata on their way to the surface, the intensity of ground shaking is significantly influenced by the subsurface soil layering and often increases in areas with deeper, softer soil deposits. The soft soils present in Utah’s valleys, deposited during the era of Lake Bonneville, tend to amplify the energy and intensity of ground motion felt by people and structures alike. Thus, the first step to designing earthquake resilient infrastructure in Utah is understanding how the subsurface soil layers amplify and/or attenuate ground motions induced by an earthquake. Methods used …
