How Tax Code Complexity Impacts Small Business Decisions In Alabama: A Mixed Method Study, George Nkosi

Dissertations

This study investigates how federal tax code complexity influences small business decision-making in Alabama using a mixed-methods approach. Tax complexity is defined by ambiguity in tax provisions, frequent regulatory changes, and recordkeeping burdens, all of which affect decision-making and investment behavior. Survey data from small business owners were analyzed using Principal Component Analysis (PCA) to identify the primary dimensions of tax complexity. Regression analysis then assessed the relationship between these dimensions and business decision-making. The findings indicate that ambiguity, frequency of change, and administrative requirements are negatively associated with long-term planning and capital investment decisions. Two complementary case studies involving …

Endoneurial Immune Interplay In Peripheral Nerve Repair: Insights And Implications For Future Therapeutic Interventions, Alina Sprenger-Svačina, Martin K R Svačina, Husniye G Otlu, Tong Gao, Kazim A Sheikh, Gang Zhang

Faculty, Staff and Student Publications

The mechanisms underlying axonal injury and repair in peripheral nerves, whether due to traumatic damage or autoimmune neuropathies, are complex and not yet fully understood. Recent research indicates that an orchestrated interplay between damaged neurons, Schwann cells, and especially endoneurial immune cells such as macrophages or T cells is crucial to achieve satisfactory nerve recovery. Following axonal injury, degenerating axons and reactive Schwann cells release chemoattractants and cytokines that recruit immune cells into the endoneurium. Among them, macrophages play a pivotal role by clearing axonal and myelin debris and subsequently creating a pro-regenerative microenvironment that supports axonal outgrowth. There is …

The Warrant Exception That Isn't: Fisa Section 702, "Defensive" Searches, And The Fourth Amendment, Noah C. Chauvin

Faculty Articles

Section 702 of the Foreign Intelligence Surveillance Act allows the government to conduct warrantless electronic surveillance of non-Americans who are located overseas. Although the surveillance targets foreigners, Americans' communications are "incidentally" collected, too. Once the government has acquired Americans' communications, court-approved rules allow it to conduct warrantless searches for and through them in its Section 702 databases. Intelligence agencies have used these rules to turn this foreign intelligence program into a domestic spying tool, conducting tens of thousands of warrantless "backdoor" searches for Americans' private communications obtained under Section 702 every year.

Section 702 periodically sunsets; Congress most recently reauthorized …

Glossed Over, Rebecca Oh

Theses and Dissertations

Glossed Over is a collection of interdisciplinary artworks exploring my Korean-American diasporic identity and how gender, queerness, religion, neurodivergence, and internet culture intersect within that experience. Through a blend of painting, woodworking, and sculpture, this installation carries the various elements of undefinable 한 (pronounced: han), a concept I attempt to define and contextualize in the Introduction and throughout this thesis. Each artwork operates through coded language, metaphor, and partial disclosure, offering space for the othered to find recognition through subtle cues and signifiers. Through Glossed Over and this thesis, I scratch the surface of my journey in reconciling generational trauma …

Effects Of Climate Change On Fungal Diversity And Function In Streams, Syeda Tasfia Imam

Masters Theses

"This study investigated the impact of climate change, particularly drought, on leaf decomposition and associated fungal and macroinvertebrate communities in freshwater ecosystems. With climate change, streams may experience altered hydrology, leading to shifts in community composition and biogeochemical processes. Fungi decompose organic matter, facilitate nutrient cycling, and support food webs. However, drought can disrupt these processes by reducing water availability, causing declines in fungal diversity and activity. I examined leaf breakdown and associated biota in 13 stream sites across varying hydrologic conditions, from perennial to ephemeral flow patterns. Flow duration varied during the 8-week study. Leaf breakdown was significantly related …

Computation Of Natural Relative Trajectories In The Elliptic Restricted Three-Body Problem, Dane Huck

Masters Theses

"Humankind’s presence in deep space is certain to increase throughout future decades. Future missions will continue to exploit the complex dynamics making use of liberation point orbits. Along with this trend is the rise of small satellites ("small sats") and fractionated spacecraft in general. Compared to traditional monolithic spacecraft, small sats can often have higher maneuverability, be a fraction of the cost, and be more expendable in nature. The growing interest in these two areas drives the need for improvements in the area of relative motion in deep space. One obvious use of small sats in deep space is for …

Ground Testing Of Cryogenic Environments In Vacuum Conditions, Lucas A. Scott

Masters Theses

The environment in the vacuum of space is unforgiving and ever-changing. Not only facing the lack of a protective atmosphere, but powerful radiation and extreme temperature ranges as well. Equipment destined for space must be hardened to withstand them. Just launching satellites that are theoretically able to survive these conditions is unfeasibly costly in the event of failure. Because of this, spacecraft must be tested in a simulated environment that can match the harsh climate in space. Therefore, it is the goal of the Gas and Plasma Dynamics Lab's (GPDL) to test and prove specific methods of recreating these conditions. …

Overpressure Waveform Comparison Of High Explosive, Methane, And Coal Dust Explosions, Frank James Schott

Masters Theses

Methane and coal dust explosions remain a leading cause of catastrophic mining accidents, making it critical to understand their overpressure characteristics for better hazard modeling, mitigation, and regulation. Although high explosives (HE), flammable gases, and dusts have been studied separately, direct waveform comparisons in identical environments are rare. This study addresses that gap by comparing overpressure waveforms from HE, methane-air mixtures, and coal dust explosions to assess differences in peak pressure, impulse, rise time, and phase duration. Twenty-seven tests were conducted using standardized instrumentation and sensor arrays. Results showed that HE generated the highest peak pressures with short positive phases …

Using Rna Sequencing To Examine Encephalic Gene Expression In Cactus Mice, Sarah A. Nicholls

Honors Theses and Capstones

Many of the exact mechanisms by which desert-adapted animals avoid dehydration-induced complications are unknown, though there are likely ties to the general mammalian dehydration response, a multisystem process spearheaded by the brain. Peromyscus eremicus, the cactus mouse, can survive its whole life without intaking water and is commonly used as a model to study desert adaptations. In this study, we have used bulk transcriptomics to characterize the differential gene expression across hydrated and dehydrated P. eremicus in five major regions of the brain: the cerebral cortex (referred to throughout much of this paper as the cortex), hippocampus, thalamus, midbrain, …
