Supernatural Law? A Refutation Of Three Recent Natural-Law Arguments Against Catholic Integralism, Jackson Dellinger

Electronic Theses and Dissertations

In the United States, there is a longstanding debate over the proper relationship between religious and civil institutions, or “church and state.” One radical voice in the debate is that of Catholic integralism, a school within Catholic social teaching which argues that Catholic governments should submit to the religious authority of the Church, and that Catholics should aspire towards a Catholic society with this relationship between Church and State for all nations. Recently, interlocutors have attempted to show that integralism is inconsistent with a core element of the Catholic teaching to which they appeal—that is, natural law. In this paper, …

The Effect Of Mandated Disclosure On Liquidity Among Not-For-Profit Organizations, Erin Johnson

Electronic Theses and Dissertations

This study examines whether mandated disclosure under Accounting Standards Update (ASU) 2016-14 affects not-for-profit (NFP) liquidity. ASU 2016-14 requires NFPs to disclose information that enhances financial statement users’ ability to assess an organization’s liquidity. Using panel data from fiscal years 2014 through 2019, I compare liquidity before and after the mandated disclosure for the top 100 revenue generating NFPs in 2019. I find that NFPs manage operating reserves, i.e., unrestricted liquid net assets, more closely to NFP sector guidelines after the disclosure mandate. Specifically, I find that NFPs with operating reserves above the recommended range prior to the disclosure mandate …

The Politics Of Being A Black Southern Belle, Latrice M. Johnson

Electronic Theses and Dissertations

“The Politics of Being a Black Southern Belle” aims to examine media representations of Black womanhood and femininity. This thesis particularly focuses on how Black women redefine the southern belle. Film and television depictions of a national (implicitly white) femininity and womanhood have historically excluded Black women. To illuminate this history, the first chapter primarily provides background on historical representations of Black women in film. American standards of womanhood and femininity have been defined according to hegemonic culture—a culture predicated on race, class, and gender. The second chapter moves into an analysis of how Black women redefine the southern belle …

Hiv-1 Tat And Neuroendocrine Aging: Potential Benefits Of Neurosteroid-Based Therapy To Attenuate Premature Age-Related Comorbidities In The Era Of Antiretroviral Therapy, Alaa Nader Qrareya

Electronic Theses and Dissertations

The primary objectives of this dissertation are to assess the interaction between human immunodeficiency virus type-1 (HIV-1) trans-activator of transcription (Tat) protein and neuroendocrine status on the pathology of Tat/age-related comorbidities and to investigate the potential benefit of hormonal therapy in attenuating Tat/age insults. The advent of combined antiretroviral therapy (cART) has increased longevity among people living with HIV (PLWH). However, cART cannot fully eradicate viral reservoirs within the central nervous system (CNS). Therefore, ~50-60% of virally-suppressed PLWH experience neurological and psychological sequelae called “neuroHIV”. Moreover, PLWH are more vulnerable to developing premature age-related comorbidities. In PLWH, hypogonadism is common …

Affording The Value Of Technology: Normalcy And Moral Frameworks, Mitchell Roberts

Electronic Theses and Dissertations

It is often held that technology is value neutral. That is, technology is merely a means to an end and has no intrinsic moral worth. However, as some theorists have demonstrated, this view of technology may be mistaken. One theorist, Michael Klenk, offers what he calls an “affordance theory of embodied values” as one principled way of understanding how technological artifacts embody moral values. Under this view, artifacts embody affordances, or possibilities for action. These affordances are then judged in order to assess the moral status of the artifact which embeds them. In this paper, I develop one problem with …

Development Of Novel Cellular Assay Model And Therapeutic Deep Eutectic Solvents To Optimize The Activity Of Anticancer Agents, Nizam Uddin

Electronic Theses and Dissertations

Multidrug resistance (MDR) is the major burden behind chemotherapeutic treatment failure. It is the principal mechanism by which cancer cells evade chemotherapeutic treatment. As a result, aggressive cancer cells survive and continue uncontrolled cell division. Multidrug resistance affects survival rate of almost all types of cancer patients and death toll rises at an alarming rate. There are seven different mechanisms for evolving MDR. The most common mechanism in efflux activity of overexpressed ABC transporters. MRP1 is a prominent ABC transporter that pumps out a wide variety of anticancer drugs from the cells and thereby reduces intracellular drug concentrations and develops …

Design, Synthesis, And Biological Evaluation Of Novel Steroidal Analogs: Potential Anticancer Agents, Trevor Ostlund

Electronic Theses and Dissertations

Cancer is a malicious disease with low survivability rates primarily due to lack of reliable treatment options. Treatments are often non-specific for patients, and cancer resistance to treatment is becoming more prevalent as fast as new therapies are created. Previous studies in our laboratory have focused on the Epidermal Growth Factor Receptor (EGFR) and its downstream kinase family members as a key target for cancer. This cascade controls cell proliferation, anti-apoptotic effects, cell regulation, and other survival factors. Additionally, ABC transporters, responsible for efflux of chemotherapeutic material from cells, are key targets to combat drug resistance. We first evaluated a …

Effect Of Genotypes On Rancidity Development During Storage Of Naked Oats, Aastha Gautam

Electronic Theses and Dissertations

Oats, rich in lipids, lipase, and unsaturated fatty acids, can develop bitterness from triglyceride hydrolysis and unpleasant aromas through unsaturated fatty acid oxidation. To counteract these effects, the processing of hulled oats includes kilning, a step aimed at inactivating the enzymes responsible for lipid degradation. Kilning plays a crucial role in preserving the quality of oats by preventing undesirable flavors development linked to lipid breakdown. Despite the benefits of free threshing and absence of a dehulling requirement in naked oats, assessing lack of enzyme inactivation during processing is crucial for potential storage rancidity issues. Our aim was to determine the …

Comprehensive Analysis And Forensic Investigation Of Cyanide, Thiocyanate, And 2-Amino-2-Thiazoline-4-Carboxylic Acid In-Ante- And Postmortem Blood Utilizing Advanced Analytical Techniques, Abdullah Hamad Alluhayb

Electronic Theses and Dissertations

Cyanide (CN), present as cyanide anion (CN-) or hydrogen cyanide (HCN), is a deadly poison. The main mechanism of CN toxicity is blocking terminal electron transfer, leading to cellular hypoxia, cytotoxic anoxia, and potential death. Determining blood CN concen-trations along with its major metabolite, thiocyanate (SCN-), is crucial. A sensitive method for concurrent detection of CN and SCN- from human ante- and post-mortem blood via liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) analysis was devel-oped. The method involved active microdiffusion with chemical modification using naph-thalene-2,3-dicarboxaldehyde (NDA) and taurine, while monobromobimane (MBB) mod-ification was used for SCN-. The method showed good sensitivity for …

Phosphate2 And Pin-Likes7 Affect Symbiotic Nodule Phenotypes In Soybean, Bhawandeep Kaur

Electronic Theses and Dissertations

Legumes and soil rhizobia share a symbiotic relationship, wherein rhizobia fix atmospheric dinitrogen in exchange for photosynthates from the host plant. This exchange of mutual benefits occurs in a specialized root structure called ‘nodule’. Soybean (Glycine max) nodules arise from root outer cortical cells. De novo cell differentiation of cortical cells during nodule development leads to the formation of two distinct nodule zones in the mature nodule: the central infection zone where nitrogen fixation occurs and the peripheral parenchyma zone that houses vascular bundles. Plant signaling mechanisms that dictate the development of these nodule zones are not known. To address …

Factors Influencing Mortality Of Bighorn Sheep (Ovis Canadensis), Emily Moberg

Electronic Theses and Dissertations

Reintroduced bighorn sheep (Ovis canadensis) in Nebraska faced a devastating pneumonia epizootic resulting in variable ewe reproductive success and poor lamb recruitment in many of the herds. From 2015-2017, no lamb recruitment was observed in the northern Pine Ridge subpopulation and as many as 60% of adults died. This was in stark contrast to the healthier Wildcat Hills herds to the south, where lamb recruitment was estimated to be between 50-70% during the same years. From 2018-2020, we radio-collared and recaptured 76 adult female bighorn sheep from 2 of 3 Pine Ridge herds and 1 of 2 Wildcat Hills herds. …
