Holocaust Education In Arkansas: An Exploration Of Policy Process And Implementation, Toby Klein Aug 2023

Holocaust Education In Arkansas: An Exploration Of Policy Process And Implementation, Toby Klein

Graduate Theses and Dissertations

The Holocaust was the attempted extermination of the Jewish people--a fact previously considered to be common knowledge. However, recent national surveys find that Arkansas students have the lowest levels of knowledge of the Holocaust in the United States. A recent law mandated the teaching of the Holocaust for 5-12th grade public school students in Arkansas, however, little is known about the policy process and implementation of such a mandate. Given the magnitude of the gaps in the literature on this topic, this dissertation uses a three article format to address specific gaps and make specific contributions to the literature by …

The Multiverse Argument For The Existence Of God, Michael Dover Aug 2023

The Multiverse Argument For The Existence Of God, Michael Dover

Graduate Theses and Dissertations

The Fine-Tuning Argument for the Existence of God is one of the most powerful arguments in favor of God’s existence. Perhaps the most common objection to this argument involves the Multiverse Theory, which posits an infinite or very large multiverse, adequately explaining the fine-tuning of the universe without positing an intelligent designer. Thus, the Multiverse Theory is often posited as a way of maintaining Atheism. In this paper, I argue that the Atheistic Multiverse View is untenable: if the multiverse exists, God or gods are highly likely to exist as well. Additionally, this paper explores topics like: the conceivability of …

Towards Multi-Modal Explainable Video Understanding, Kashu Yamazaki Aug 2023

Towards Multi-Modal Explainable Video Understanding, Kashu Yamazaki

Graduate Theses and Dissertations

This thesis presents a novel approach to video understanding by emulating human perceptual processes and creating an explainable and coherent storytelling representation of video content. Central to this approach is the development of a Visual-Linguistic (VL) feature for an interpretable video representation and the creation of a Transformer-in-Transformer (TinT) decoder for modeling intra- and inter-event coherence in a video. Drawing inspiration from the way humans comprehend scenes by breaking them down into visual and non-visual components, the proposed VL feature models a scene through three distinct modalities. These include: (i) a global visual environment, providing a broad contextual understanding of …

Anti-Inflammatory Effect Of Apiaceous Vegetables In A Mouse Model Of Colitis - Implications For Colon Cancer Risk, Laura Mariana Mariana Echavarri Ibarra

Graduate Theses and Dissertations

Colorectal cancer is the second leading cause of cancer-related deaths in the US. Dietary habits account for 50% of the cases. A westernized diet (high fat, high sugar/fructose, and low in fruits and vegetables) and inflammatory bowel diseases are risk factors for colorectal cancer. Evidence suggests phytochemicals in apiaceous vegetables (API; celery family) possess anti-inflammatory and potentially chemopreventive properties. Hence, investigation of whether the consumption of API mitigates acute colitis is warranted. Using mice fed the Total Western Diet (TWD) and administered dextran sodium sulfate (DSS; induces colitis), the objectives of this project are to identify the effects of API …

Decrypting The Processes Of Policy Evolution: Comparing Québec And Ontario’S Evolution Of Risk Management Policies, Frederick Clerson Guicherd Aug 2023

Decrypting The Processes Of Policy Evolution: Comparing Québec And Ontario’S Evolution Of Risk Management Policies, Frederick Clerson Guicherd

Graduate Theses and Dissertations

Through policies or programs, states can influence industries to align with their vision of what a sector should become. However, this vision is subject to influence from actors of the industries which emphasize the importance of the relationship between the state and interest groups. In this dissertation, we observe the evolution of 9 Canadian agriculture risk management programs implemented by two provincial governments between 1990 and 2020 to understand how such programs coped with the new trends in agriculture. Through a review of parliamentary discussions and official documents, we evaluate the factors that justified program evolution based on the combination …

Cullin 3–Mediated Regulation Of Intracellular Iron Homeostasis Promotes Thymic Invariant Nkt Cell Maturation, Emily L. Yarosz, Ajay Kumar, Jeffrey Singer, Cheong-Hee Chang

Biology Faculty Publications and Presentations

The E3 ubiquitin ligase cullin 3 (Cul3) is critical for invariant NKT (iNKT) cell development, as iNKT cells lacking Cul3 accumulate in the immature developmental stages. However, the mechanisms by which Cul3 mediates iNKT cell development remain unknown. In this study, we investigated the role of Cul3 in both immature and mature thymic iNKT cells using a mouse model with a T cell–specific deletion of Cul3. We found that mature iNKT cells lacking Cul3 proliferated and died more than wild-type cells did. These cells also displayed increased glucose metabolism and autophagy. Interestingly, we found that tight regulation of iron homeostasis …

Lepton Flavor Violation And Lepton Flavor Universality Violation: Opportunity For New Physics Beyond The Standard Model, Fang Xu

Arts & Sciences Graduate Student Theses and Dissertations

The Standard Model (SM) of Particle Physics has been remarkably successful in explaining the fundamental forces and classifying elementary particles. However, there are various experimental and theoretical indications that suggest the need to go beyond the SM (BSM) and expand our understanding of the fundamental nature of the universe. From a theoretical perspective, there are several limitations of the SM that suggest the existence of a more fundamental theory. For example, the SM does not incorporate gravity, and it fails to explain the hierarchy problem. Additionally, the nature of dark matter and the origin of the mass hierarchy of elementary …

“‘State Of War’: British Racial Construction, New World Slavery & The Impact Of Somerset’S Case In The Anglo-American Diaspora", John David Kemp Aug 2023

“‘State Of War’: British Racial Construction, New World Slavery & The Impact Of Somerset’S Case In The Anglo-American Diaspora", John David Kemp

Dissertations

On Monday 22 June 1772, the English jurist William Murray, 1st Earl of Mansfield, delivered his oral verdict as Chief Justice of the Court of King’s Bench in the famous case involving the enslaved Afro-British servant James Somerset to declare that only an Act of Parliament could legalize domestic bondage and that Somerset was a free man. For the estimated 15,000 captives living in the English metropole, Somerset v. Stewart effectively undercut the Anglo-Atlantic slavocracy that had hid behind legal technicalities and extrajudicial decrees defending domestic bondage since the last quarter of the seventeenth century. In order to offer a …

Experiences With Writing And Reading Neuropsychological Reports: Neuropsychologist And Parent Perspectives, Zsofia Imre Aug 2023

Experiences With Writing And Reading Neuropsychological Reports: Neuropsychologist And Parent Perspectives, Zsofia Imre

Dissertations

Researchers have described common problems with psychological reports over the past several decades. Some of these issues can contribute to difficulties for neuropsychologists (e.g., efficiency, insurance reimbursement). Additionally, these problems contribute to difficulties with feasibility, readability, and satisfaction for the readers of psychological reports. However, research has been limited on the perceptions of neuropsychological reports specifically, especially related to parent experiences with neuropsychological reports. Hence, this study sought to understand the current report-writing trends, parents' experiences and satisfaction, and neuropsychologists' openness to adjusting their report-writing styles. Data were obtained through surveying parents and neuropsychologists on their experiences reading and writing …

Fat And Queer: A Qualitative Exploration Of Womens' Experiences Of Fatphobia, Jaidelynn Keeley Rogers Aug 2023

Fat And Queer: A Qualitative Exploration Of Womens' Experiences Of Fatphobia, Jaidelynn Keeley Rogers

Dissertations

A paucity of psychological research exists on the topic of fatphobia, a type of pervasive oppression that occurs for people with plus-size, large, and/or fat bodies. Much of the research that exists about fatphobia focuses on medical ideals, the associated weight stigma, and how these are related to fat people’s physical health. Medical researchers have determined that weight stigma is actually more harmful to fat people's health than being fat. Fatphobia impacts women at disproportionate rates. Plus-sized, queer, lesbian, bisexual, and pansexual (LGBTQ+) women may be at a heightened risk for experiencing marinization as a result of their intersecting identities …

The Aesthetics Of News: Narrative Construction And Media Illiteracy In Contemporary India, Shashidhar Nanjundaiah Aug 2023

The Aesthetics Of News: Narrative Construction And Media Illiteracy In Contemporary India, Shashidhar Nanjundaiah

Dissertations

Amidst the public’s declining trust in news, media prosumers—that is, media consumers who have also become producers of mediated texts—are not equipped with any credible alternative mechanism to better understand the world around them. Prior academic studies of news and its delivery have not adequately explored the ideological framework we need to confront this frightening situation. This dissertation does so. I problematize the narration of news as an aesthetic process. Such mass-mediated narration stitches together our world in ideological ways. A tidal flow of stories highlights and obscures selected truths in a frenzy of “new” news cycles, the frequency of …

Does Reading Historical Drama Increase Historical Knowledge And Empathy? The Case Of Dorothy Sayers’S The Man Born To Be King, Albert Cheng Aug 2023

Does Reading Historical Drama Increase Historical Knowledge And Empathy? The Case Of Dorothy Sayers’S The Man Born To Be King, Albert Cheng

Education Reform Faculty and Graduate Students Publications

Literary theorists have argued that literary reading fosters empathy, a claim that has substantial empirical support. In this study, I consider the more specific case of reading historical drama and its potential to foster historical empathy among secondary school students. Although several educational interventions for fostering historical empathy have been proposed, none have yet considered the potential of reading historical drama. I evaluate an intervention where students engaged with selected plays from Dorothy Sayers’s The Man Born to be King that depict the Nativity and Easter narratives. After the intervention, I find that these students, compared to students who did …
