Lost In The Times Of Yesterday And Other Stories, Anes Ahmed

Theses and Dissertations

Lost in the Times of Yesterday is an ongoing collection of fiction that features short stories who, while varying differently from one another, are all intertwined by the themes of immigration, post-colonialism, and Arabic and Arab-American identity, aiming to capture the diverse orchestra of Egyptian and Egyptian-American voices through the lens of magical realism. Some examples: the grief of a village girl and her attempt to understand her father’s ghost; an Egyptian-American actor whose slow physical disappearance leads to an examination of identity within contemporary performance; and the life of boy born with chestnut wings in a Brooklyn apartment.

Renewable Energy Policies In Fairbanks Alaska: Benefit-Cost Analysis Of A Carbon Tax And A Renewable Portfolio Standard For Golden Valley Electric Association, Kylie Reese

Theses and Dissertations

The electricity sector is a major producer of carbon dioxide emissions. Specifically in Fairbanks, Alaska. The electricity sector is also a producer of PM2.5 emissions. PM2.5 emissions are particles that form in the air from complex chemical reactions in sulfur dioxide and nitrogen oxides which are emitted from nonrenewable power plants. Research shows (Wu, 2023) that both carbon emissions and PM2.5 emissions have negative influences on the environmental and social welfare of citizens. Carbon emissions contribute to climate change, while PM2.5 emissions pose serious threats to human health. In 2009, the Fairbanks North Star Borough (FNSB) was declared a nonattainment …

Soil Carbon Sequestration Efforts In Arid And Semi-Arid Climates Under Conservation Agriculture And Reforestation, Samantha Lynn Colunga

Theses and Dissertations

Soil organic carbon (SOC) plays a vital role in the global carbon cycle and aids in climate change mitigation. However, deforestation and intensive agricultural practices threaten topsoil and carbon (C) pools through soil disturbances releasing vast amounts of carbon dioxide (CO2) by enhancing the decomposition of organic materials. Degraded soils typically lack stable aggregates, nutrient and water retention, and overall low fertility. In arid and semi-arid regions, soils are in an even more dire situation, as low precipitation and high temperatures slow down the accumulation of SOC. This thesis has two objectives: 1) to evaluate whether conservation tillage practices increase …

Affective Life, Mobility And Unity In U.S.-Mexico Transborder Families, Aaron A. Adame Sosa

Theses and Dissertations

There has been abundant research on transnational families and their lived realities, but most of this research focuses on analyzing family relations across long distances. This thesis examines transnational life at the borderlands and develops new frameworks for understanding family unity and separation. Using concepts from the sociology of emotions, I find that economic and opportunity inequalities structure much of transborder life and that the emotional work different family members do for the sake of their family unity is largely based on mobility privilege and the idea that the U.S. is economically better off, even as the relative poverty between …

Ecologies Of Teaching With Bilingual Students: Connecting Identity, Agency, And Assessment In First-Year Writing Class, Sumantha Nikole Zapata

Theses and Dissertations

As many students who graduate from high school transition into applying for college or university, they are not aware of the drastic changes that come with it. For bilingual students, this transition can be much more challenging due to their language barrier and the lack of support they may receive. The intersection of demographics, pedagogy, and linguistic agency led to the research question for this study: how can pedagogies in first-year writing classes be adjusted or developed to justly educate and assess bilingual students who are still working toward competence in English? The history of bilingual education …

Tarnished Glory: The Exclusion Of Buffalo Soldiers In World War I, David Michael Barron

Theses and Dissertations

This thesis examines the exclusion of the Buffalo Soldier regiments during World War I. Due to the rise of racial discrimination in the early twentieth century, the Buffalo Soldier regiments experienced violence with civilians while stationed in the United States. The violence experienced by African American soldiers would shape decisions that would ultimately impact their involvement in World War I. By examining evidence from their war record in previous conflicts and evidence from the racial violence that occurred while stationed in the US, this thesis will show that their exclusion in World War I was due to poor conduct perpetrated …

Denoising Diffusion Probabilistic Models Based Accelerated Mri, Alexander Francis Bugielski

Theses and Dissertations

Magnetic Resonance Imaging (MRI) is a cornerstone in obtaining intricate visualizations of anatomy and physiological processes within the human body. However, its extensive scan duration not only causes patient discomfort but also increases the likelihood of motion-induced artifacts in the images. To address such a challenge, this study investigates deep neural network models for reconstructing high-resolution MRI images from noisy and significantly undersampled data in a supervised learning manner. Specifically, it compares three models: a conventional U-Net, a self-attentive U-Net, and an innovative probabilistic diffusion model that builds upon the self-attentive U-Net architecture. These models are evaluated on their ability …

Water Quality Hotspot Analysis On Chlorophyll-A To Monitor Harmful Algal Blooms In Small And Medium Lakes Of North Dakota, Sae Young Lee

Theses and Dissertations

The water quality of recreational lakes degrades with Harmful Algal Blooms (HABs). HABs can block sunlight, lower oxygen levels, and may produce toxins. Industrial and domestic waste and fertilizer runoffs can enrich nutrients for HABs. Chlorophyll-a (Chl-a) is a significant indicator for tracking HABs and has been monitored increasingly using remote sensing techniques. In search for significant trends in hotspots of Chl-a concentrations in small and medium lakes of northeastern North Dakota, Chl-a water samples were collected in summer and fall of 2023. The study lakes include: Fordville Dam Recreation Area, Larimore Dam RecreationArea, Homme Dam Recreation Area, and South …

Subversive Compliance In A Precarious Nation: Camp In The Skopje 2014 Project, Lila Rice

Theses and Dissertations

To promote their desired national identity, the North Macedonian government funded the Skopje 2014 Project––an initiative including abundant statues, architectural façades, and other structures that depict Ancient Macedon as North Macedonia’s heritage. This project received copious amounts of criticism on two central fronts: first, that its allusions to Ancient Macedon are a false depiction of history; second, that its aesthetic is tacky. While valid arguments are made on each of these fronts, I argue that the latter complicates the former when analyzed in the context of North Macedonia’s precarity. In this analysis, I employ the work of Judith Butler and …

Andromedus: A Novel, Ariel Renae Hochstrasser

Theses and Dissertations

Andromedus "Midas" Hellebore is a half-fae necromancer living in Portland, Oregon. When he was a child, he grew up in a brothel on a fae territory near the Pacific coast on an island called Duckwell. The matron of said brothel tried to sell him to be a blood pet for a man named Mr. White, both to be a sex slave and to consistently produce fae blood, which consumed by humans could give them the magic fae folk are born with. However, a few of the escorts at the brothel - including Orla, the one who chose to raise him …

Objects And Museal Rhetoric, Isaac James Richards

Theses and Dissertations

Rhetoricians of public memory are interested in materiality. Simultaneously, they seek to recover, promote, and commemorate historically marginalized populations. These twin objectives form a paradox: how does one study public memory in contexts where material manifestations are limited or lost to history? What of peoples and cultures whose histories of erasure have left them with insufficient material to stock a traditional museum? To explore these questions, I examine museal spaces, or places of public memory that are atypical when compared to normative museums, even as they maintain some museum-like features. More specifically, I examine the various rhetorical effects of objects …

"A Love That Transcends Hunger": Choice And Edenic Imagery In Contemporary Queer Poetry, Aubrey Dickens

Theses and Dissertations

Contemporary poets such as Richard Siken are known for their sexual and explicitly queer nature. Others have debated the spiritual dimension of queer poetry such as Siken's, with individuals such as Marta Figlerowicz arguing that though one of Siken's poems calls itself a litany, it does not match all the rules of a litany due to not being clearly devotional. Using an outside-in analytical approach to Richard Siken's "Snow and Dirty Rain," Kayleb Rae Candrilli's "There is a Point at Which I Tire of My Own Fear," and Jericho Brown's "Eden", I argue that spirituality can be found in explicit …

Resonance: A Methodology And Pedagogy For Socially Just Storytelling, Helen Plevka-Jones

Theses and Dissertations

Through a close analysis of Valeria Luiselli’s Lost Children Archive and a comparative analysis of the intertexts it references, this dissertation argues that literary scholars and literacy pedagogues can learn from sound studies and archival practices together to achieve more socially just reading, writing, and teaching. The novel narrates a family traveling across the United States, not only experiencing their own journey but also learning about past forced migrations upon the same land and present attempted migrations into the country. As they encounter and interact with different print, audio, and visual artifacts, the characters achieve a more inclusive and complex …

Mechanical Characterization Of Hemp, Jute, And Flax Based Natural Fibre Composites For Non-Structural Applications In Aircraft And Automobiles, Ravi Kumar B

Theses and Dissertations

Demand for reducing energy consumption and detrimental environmental impacts after the effective lifetime of an engineering material are the major driving factors for the development of natural fibre reinforced composites (NFRCs) in various sectors. Compared to synthetic fibre like carbon-fibres or Kevlar, natural fibres provide several benefits including light weight, inexpensive, recyclability, superior specific strength, biodegradable, non-toxic during handling, and less energy intensive during manufacturing. This doctoral work presents observations from mechanical tests and interpretations on the suitability of natural fibre reinforced composites for less heavily loaded engineering applications areas.

In the first stage, jute, flax, and hemp fibres were …

Persuasion Strategies Employed On Instagram By Latter-Day Saint Religious Social Media Influencers, Ashton Everett Hatch

Theses and Dissertations

A content analysis of Latter-day Saint Instagram influencers is relevant to understanding what persuasive elements religious social media influencers include in their content. Observing instances that influencers persuade, establish credibility, develop trust, forge logical arguments, and engage the emotions of followers allow influencers to understand what constitutes engaging content. This study found that Latter-day Saint Instagram influencers posted emotive content that encouraged followers to continue to engage with their content, and/or endorsed another account or organizational influencer. This combination of pathos persuasion and endorsement authenticity shows that followers seek to participate in religion online as part of their regular worship.

Inservice Professional Development For Educators In A Democracy: Moving From Theory To Practice, Rachel Lynn Wadham

Theses and Dissertations

This dissertation presents research that addresses the question of how professional development influences inservice teachers' professional identity. In three journal articles, specific inquiries address research questions drawn from this broader conversation. In article one, we answered the question of what unifying characteristics democratic educators exhibit in their pedagogies and methods. By conducting an integrative literature review, we find that those who indicate that they are democratic educators used four major pedagogical categories including inquiry methods, artistic methods, oral methods, and student-centered methods. In the second article, we addressed the question of how professional development influences teachers' professional civic identities. In …

Association Between Direct Access Laws And Physical Therapy Use And The Effect Of Change In Physical Therapy Use On Subsequent Healthcare Spending, Utilization, And Opioid Use, Dakshu Jindal

Theses and Dissertations

Background

Physical therapy (PT) has been recommended as the first-line treatment for patients with incident musculoskeletal conditions without severe trauma. Initial or early use of PT may help address some of the nation’s most pressing health policy challenges, including escalating healthcare spending and an ongoing opioid epidemic, by encouraging the use of physical therapy as a substitute for expensive surgeries and the use of opioids. Yet, state scope of practice laws have historically restricted the diagnosis and treatment of medical conditions to physicians. Traditionally, patients seeking care from a physical therapist had to obtain a referral from a physician first. …

The Influence Of Tile Flow On The Transport-Fate Of Nitrate In The Vadose Zone Of A Saturated Riparian Buffer: A Case Study At The T3 Site In Mclean County, Central Illinois, Benedicta Karl Akrofi

Theses and Dissertations

The Midwest states have highly fertile soils representing one of the world's most intense agricultural production areas. The agricultural lands in the Midwest, including Illinois, are drained using tiles to improve the soil conditions for high productivity. However, the discharge of the tile waters directly into streams short-circuits the soil’s role in nutrient cycling (plant uptake, denitrification, microbial immobilization) and contributes to elevated nitrate as nitrogen (NO3--N) concentrations in surface waters, causing algae blooms which impairs surface waters and degrade water quality. Most NO3--N exports from tile-drained watersheds in the Midwest occur from January to June, corresponding to periods of …

Influence Of Tile-Drainage Water On Groundwater Nitrate Concentrations: A Case Study Of A Saturated Riparian Buffer Zone, Tosin Aminat Abdulsalam

Theses and Dissertations

In the U.S. Midwest, where fertile soils with high water retention are prevalent, the installation of tile drainage networks have become a common practice to drain excess soil water, enhancing plant growth and increasing crop productivity. However, tile drainage networks coupled with the use of inorganic fertilizers have significant implications on water quality, contributing to eutrophication, leading to harmful algal blooms, and resulting in hypoxic conditions in surface water bodies. To mitigate excess nutrient exports to surface water bodies, edge-of-field practices have been introduced. One such practice is the saturated riparian buffer (SRB), which utilizes a diversion system to redirect …

Decoding The Past: Evolutionary History Of North American Deer Mouse Populations On The Gulf Islands, Rachel Ann Berg

Theses and Dissertations

Anthropogenic habitat fragmentation is increasing the number of small and isolated organismal populations, and the long-term effects of these recent isolations are not well understood. Small populations are at increased risk of extinction thus it is essential to identify populations that have been isolated over long time periods to use as model systems to study consequences of isolation. Besides understanding genetic consequences, isolated populations may also serve as natural systems to study morphological changes in populations that have independent evolutionary trajectories. Investigating island populations may help in the discovery of long-term isolated populations that may be experiencing morphological changes as …

Back In The Ring: A Survey Of The Communist Party Of The United States: 1956-1976, Zachary Carlson

Theses and Dissertations

The Communist Party of the United States (CPUSA) suffered greatly under McCarthyism and by 1956 was no longer considered a viable political party by contemporary historians. Therefore, contemporary historians ignore the efforts of the CPUSA after this date. Failure to engage with the CPUSA post 1956 ignores their activity and contribution to the political and social landscape of the United States during the New Left, Civil Rights Movement, and Anti-War Movement. The CPUSA remained an influential political party and organizing power during the post-McCarty years. This survey exemplifies the methods used and spaces occupied by the CPUSA that allowed them …

Building Community Support: A Multi-Scalar Archaeological Analysis Of Sewage Infrastructure In Central Illinois, Anastasia Leigh Ervin

Theses and Dissertations

In the 1920s and 1930s in Central Illinois, urban areas implemented sewage infrastructure consisting of underground sewers and sanitation plants. These sanitary districts soon became an essential service provided within the community and the established infrastructure has undergone expansion and technological updates in the decades since. I use methods and concepts of landscape archaeology in combination with 1940 Census socio-economic demographics, GIS viewshed and smellshed (buffer) analysis, and visual spatial analysis to examine the case studies of three sanitary districts in Central Illinois: Bloomington-Normal, Urbana-Champaign, and Sangamon County to evaluate how these infrastructures shaped their landscapes, or sewagescapes. Sewagescapes have …

Gt-Ches And Dycon: Improved Classification For Human Evolutionary Systems, Joseph S. Johnson

Theses and Dissertations

The purpose of this work is to rethink the process of learning in human evolutionary systems. We take a sober look at how game theory, network theory, and chaos theory pertain specifically to the modeling, data, and training components of generalization in human systems. The value of our research is three-fold. First, our work is a direct approach to align machine learning generalization with core behavioral theories. We made our best effort to directly reconcile the axioms of these heretofore incompatible disciplines -- rather than moving from AI/ML towards the behavioral theories while building exclusively on AI/ML intuition. Second, this …

Reimagining Rural Readiness: Examining The Challenges Of The Rural Working-Class In Education, Todd Dugan

Theses and Dissertations

ABSTRACT Rural students comprise nearly half of all students enrolled in public schools in the nation. With increasing amounts of students living in poverty, rural school districts are combatting many issues but with less resources than urban and suburban school districts. In addition, new Federal and state regulations continue to be enacted, sometimes to the detriment of students from rural working-class backgrounds. The research design consisted of a collection of memories from the author, who grew up in a rural working-class family and spent a career teaching and leading schools from this demographic, in an autoethnographic journal narrative format. To …
