Digital Twins For Ancillary Transportation Asset Data Management, Ashtarout Ammar

Theses and Dissertations--Civil Engineering

Transportation Asset Management (TAM) is a data-driven decision-making process to maintain and extend the serviceability of transportation assets throughout their lifecycle. TAM is an extensive data process requiring accurate, high-quality information for better decision-making. A significant challenge that state Departments of Transportation (DOTs) face is allocating limited funds to optimize their assets’ performance. The criticality of this challenge increases when state DOTs need to manage a wide variety of assets distributed along with a vast network; thus, they prioritize the management of high-value assets and visible ones such as bridges, and they pay less attention to ancillary assets even though …

Development And Validation Of An Instrument To Measure Teacher Self-Efficacy For Meeting The Needs Of Military-Connected Children, Amy M. O'Neill

Theses and Dissertations--Education Sciences

The average military child changes schools six to nine times before graduating high school. With those moves come significant educational challenges, but there is currently no known instrument designed to measure whether teachers believe they are capable of meeting the needs of this population. The purpose of this study was to develop, pilot, and provide initial psychometric evidence for a scale, the Teacher Self-Efficacy Scale for Military Kids (TSES for MilKids), that measures teacher self-efficacy for meeting the needs of military-connected children. A 19-item instrument was created and distributed to regular education teachers in Grades 1-5 in civilian school districts …

Theses and Dissertations--Education Sciences

Transitioning from high school to higher education is one of the most stressful times in a person’s life. But, for the undergraduate students who were freshmen during the fall of 2020 (in the middle of the COVID-19 pandemic), this predictable stress was compounded by additional stressors related to the pandemic. While there were undoubtedly many teaching factors that made learning more difficult during the pandemic, there were also many aspects of teaching that these freshmen found helpful. This exploratory study of secondary data sought to discover which aspects of teaching were most helpful to the COVID Freshmen (the students who …

The Protection Of Student Data Privacy In Wisconsin School Board Policies, Curtis Clyde Rees

Theses and Dissertations--Education Sciences

American schools have increasingly adopted technology resources to fulfill their educational obligations. These tools are for instruction, communication, and storing and analyzing student information. Student data can be directory information, enrollment records, achievement data, and student-created products. This increased utilization began with the passage of No Child Left Behind in 2001, and the COVID-19 pandemic led to more educational technology use of student data. Districts turned to third-party vendors for assistance with data systems and virtual learning resources. Before, during, and after the pandemic, stakeholders were concerned about information security and the students' privacy. School leaders looked to federal regulations …

Principal Leadership Practices At Kentucky High Schools Administering The Pisa For Schools: Leading For Global Competitiveness, Marjorie L. Johnson

Theses and Dissertations--Education Sciences

Since launching Sputnik in 1957, the United States education system has been trying to climb to the top of the international education rankings. The Organisation for Economic and Co-operative Development (OECD) began analyzing how well school systems prepared students to compete in the global economy in 2000. The OECD uses the Programme for International Student Assessment (PISA). U.S. students rank at or near the OECD averages in reading and science but consistently perform below the OECD average in mathematics. In addition to the PISA, the OECD released the PISA for Schools, which provides PISA data at the school level.

The Thin Line In The Bluegrass Schools: A Quantitative Study On How School Resource Officers Impact A School And District's Use Of Exclusionary Discipline In Kentucky, Mia Morales

Theses and Dissertations--Education Sciences

Legislatures across the country have been developing laws and policies to place police officers, also known as School Resource Officers (“SROs”), in schools. A recent piece of legislation in Kentucky, entitled the School Safety and Resiliency Act, requires all school campuses in Kentucky contain at least one SRO. Researchers have found relationships between the presence of SROs and the use of exclusionary discipline, and this research expands on that foundation by looking statewide at school- and district-level variables.

Using a multiple regression model, this research examined the presence of SROs in schools and the ratio of number of SROs to …

A Quantcrit Investigation Of The Discriminatory Practices In Texas Education Funding, Stuart Andrew Keogh

Theses and Dissertations--Education Sciences

The Texas constitution guarantees citizens a "general diffusion of knowledge" and an "efficient system of public free schools." However, the state has often failed to provide sufficient funding to meet this constitutional mandate. Many school districts, especially those serving low-income or minority communities, have been chronically underfunded. This has led to unequal access to quality education. As a result, there have been numerous lawsuits challenging the constitutionality of Texas's school funding system. Plaintiffs argue that the state has violated the education clause of the constitution by failing to adequately and equitably fund public schools. Despite several legislative attempts at reform, …

Qualitative interview data from high school student focus groups was analyzed using grounded theory to develop themes related to PBIS implementation.

Using open and axial coding, themes were developed from common student interpretations of PBIS within focus groups. Participants discussed a variety of positive techniques teachers use inside the classroom and responses to student behavior. Reward systems were discussed, but more importantly students offered suggestions of interventions and supports to offer at school. When asked to …

Vapr, Henry Knollenberg

Theses and Dissertations--English

vapr is a collection of short stories loosely interconnected via an anthropoid of smoke self-titled the Antimmanuel. vapr is an acronym for VOID & AUGURY & PRESENCE & RESIDUE; there is nothing else, and it is all ephemeral. The Antimmanuel is the guide; it is there with us even when god is not – within capitalism, within religion, within mental health crises, etc. Although very much not a work of Realism, this collection of eight stories grasps for, at the very least, its own author’s understanding of the real – what it feels like to live in middle America in …

Conceive And Control: Cultural-Legal Narratives Of American Privacy And Reproductive Politics, Emily Naser-Hall

Theses and Dissertations--English

Law and literature share a foundation in narrative. The literary turn in legal scholarship recognizes that the law itself is a form of narrative, one that simultaneously reflects socio-cultural norms and creates social and political regulations with a complex matrix of power. Cultural narratives from the 1950s to the mid-1970s pertaining to reproductive politics, domesticity, and national identity both produce and are productive of legal rulings that govern and restrict private acts of sexuality and speech. The Supreme Court used cases concerning sex and reproduction to enumerate, explicate, and complicate the right to privacy, which appears nowhere in the U.S. …

Stick With Me: Essays, Clay Shields

Theses and Dissertations--English

A small-town Appalachian deviant confronts the frequent, recurrent grief of the opioid crisis and its mortal, psychological, and communal consequences. This collection endeavors to explore substance use, addiction, geopolitical exploitation of Kentucky, central Appalachia, and surrounding areas, while also celebrating the lives of individual loved ones lost to deaths by suicide, drug overdose, and alcoholism. Here, the common narrative of depravity surrounding addiction is challenged through the rendering of full characters capable of love, trust, friendship, humor, mental health management, and personal growth. Time and place factor fundamentally into the stories told here—whether based in central Kentucky or central Appalachia, …

From Jane Austen To Meghan Markle: The Persistence Of British Imperialism In White Popular Feminism, Kathryn M. Kohls

Theses and Dissertations--English

This dissertation traces the persistent threads and values of white womanhood from the nineteenth-century British Empire to modern American popular culture. The figure of the white woman was significant to upholding colonialism and empire in the literary mass media and culture of the nineteenth century, and I argue that this figure continues to be used in popular media and online content today to surreptitiously uphold white supremacy and obscure race and gender inequalities. This dissertation will explore the overlaps between nostalgia, historical revisionism, white womanhood, white supremacy, and white feminism in modern American popular culture. The connections between, and the …

Myth, Mockery, & Misery: An Evolution Of Disillusion In Modern-War Expression, Richard W. Halkyard

Theses and Dissertations--English

Industrialization in 19th-Century America yielded a regrettable by-product: the modernization of warfare. Mass armies, technological innovation, and unprecedented rates of industrial productivity prompted the creation of machines designed to inspire fear, increase destructive capability, and inflict mass-death. The modernization of warfare altered forever the way war was experienced and represented literarily. Authors who attempted to represent the Civil and Spanish-American Wars, as well as World War I, articulated modernized warfare with a disillusionment which stems from the tragically dehumanizing effects of mechanical violence on an industrial scale. Myth, Mockery, & Misery argues that as far back as 1862, romantic idealization …

Exploring The Molecular Basis Of Touch: A Comparative Analysis Of Gene Expression In Sensory Corpuscle-Rich And Corpuscle-Poor Skin Regions In The Duck, Thomas Hart

Theses and Dissertations--Biology

Cutaneous touch is facilitated by discrete cellular complexes composed of non-neuronal cells associated with mechanoreceptor neuron endings. The non-neuronal cells of these cutaneous end organ complexes (CEOCs) are believed to contribute to touch, but their role in touch sensation remains unclear. To better understand the function of CEOC cells, we sought to characterize the transcriptional profile of CEOC-rich tissue and identify genes expressed in CEOC cells. Bill skin of the tactile foraging Pekin duck (Anas platyrhynchos) is dense with CEOCs, specifically the avian analogs of mammalian Pacinian and Meissner corpuscles, while corpuscles in duck foot skin are scarce. Using RNA …

Theses and Dissertations--Earth and Environmental Sciences

As part of ongoing research on radionuclide mapping and radon hazard characterization, field tests were performed to evaluate the suitability and limitations of a UAV-compatible gamma spectrometer. To date, this data set includes completed stationary data collection, mobile ground collection, multi-level UAV flights over a known material transition, as well as redundant ground and multi-level UAV data collection over a relatively uniform area. Total counts were used as a measure of soil radionuclide levels for our data collected above background. Although our test sites were in regions underlain by bedrock with high indoor radon levels, uranium counts were barely above …

Picturing The Future City: Digital Mediation And Creative Placemaking, Jessica Mccallum Breen

Theses and Dissertations--Geography

Creative placemaking is an arts-oriented community development policy that focuses on the potential for art, artists, and cultural organizations to generate social, economic, and cultural vibrancy in their communities and is a primary tool of culture-led (re)development practices (Markusen & Gwada, 2010). Despite the focus of creative placemakers on the local impacts of their work, creative placemaking is more than local, it is both translocal and transcalar. In this dissertation, I examine the role that digital mediation plays in creative placemaking and how it makes visible these translocal and transcalar connections. I begin by outlining a methodology for tracing replicated …

It's Football Time In The Bluegrass!: The Community Of Uk Football Athletes & Fans And Their Shared Language & Religious Practices, Virginia Anderson

Theses and Dissertations--Linguistics

This thesis observes how University of Kentucky fans and athletes create both a community and a religious experience surrounding the sport of football through their use of language. Fans and athletes took part in interviews that implicitly asked about religious experiences and community. Once the interviews were completed, they were transcribed and underwent open thematic coding. Themes were gathered from the interviews and compared to determine if the fans and athletes were separate subcommunities or if they were simply part of the at-large University of Kentucky football program community. These themes also aided in determining if and how fans and …

Orphans, White Unity, And The Charleston Orphan House, 1860-1870, Ruth Poe White

Theses and Dissertations--History

This dissertation explores the ways the Charleston Orphan House, a nineteenth-century whites-only benevolent institution, promoted white unity in South Carolina between 1860 and 1870. Just as it had during the antebellum era, the Orphan Home knit together white society by providing poor white families a source of social security, middling white families a source for cheap labor in the form of indentured service, and elite whites an opportunity to display social prominence. Yet, maintaining this delicate balance throughout the siege of Charleston and the Home’s eventual evacuation to Orangeburg, South Carolina was no easy feat. The Chairman of the Board …

Enduring The Elements: Civil War Soldiers’ Struggles Against The Weather, Cameron Boutin

Theses and Dissertations--History

This dissertation is an environmental history that studies the variety of ways that soldiers in the American Civil War experienced the pressures of weather over the course of their military service. For the troops of the U.S. and Confederacy, the weather was more than simply a passive backdrop to their time in the military, but a central preoccupation. This dissertation analyzes how weather intersected with some of the most central experiences of soldiering – tent camping and winter quarters, marching, bivouacking, manning sentry posts and field fortifications, and fighting in battles. Life in Civil War armies consisted of all of …

From Displaced To Displacers: Scottish Crofters, First Nation Peoples And Commons Enclosure From The 1700s To The 1800s, Anna Herrington

Theses and Dissertations--History

In the 18^th and 19^th centuries, the enclosure of common systems shaped the displacement of people on a global scale whilst bringing the people---Scottish Highland crofters and Mi’kmaq First Nation Canadians from the margins where they have dwelled for centuries in historical scholarship to of the centre of not just their history, but our collective history. Both populations experienced attacks on their ties to their lands, resources, and culture through enclosure. The enclosure process lasted over two centuries and was interspersed with violent protest, proactive resistance, interspersed with periods of acceptance and determination against their forced removals. Investigating …

Novel Architectures And Optimization Algorithms For Training Neural Networks And Applications, Vasily I. Zadorozhnyy

Theses and Dissertations--Mathematics

The two main areas of Deep Learning are Unsupervised and Supervised Learning. Unsupervised Learning studies a class of data processing problems in which only descriptions of objects are known, without label information. Generative Adversarial Networks (GANs) have become among the most widely used unsupervised neural net models. GAN combines two neural nets, generative and discriminative, that work simultaneously. We introduce a new family of discriminator loss functions that adopts a weighted sum of real and fake parts, which we call adaptive weighted loss functions. Using the gradient information, we can adaptively choose weights to train a discriminator in the direction …

Investigation Of Key Mechanisms Of Contact Dependent Growth Inhibition Systems In Burkholderia Cepacia Complex Species, Zaria K. Elery

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Burkholderia cepacia complex is a group of closely related environmental bacteria that can exacerbate disease in immunocompromised individuals. B. cepacia bacteria are equipped with an arsenal of mechanisms to cooperate and compete for nutrients in various polymicrobial environments. Contact-dependent growth inhibition (CDI) systems are antagonistic mechanisms widespread among proteobacteria. CDI systems consist of Two Partner Secretion pathway proteins that function to deliver the toxic C-terminal portion of the large effector exoprotein (termed ‘BcpA’ in Burkholderia-type CDI systems) to the cytoplasm of a compatible recipient bacterial cell upon direct cell to cell contact. The translocation of BcpA out of the …

Investigating The Relationship Between Metabolic Reprogramming And Peripheral Cd4+ T-Cell Inflammation In Human Type 2 Diabetes Pathogenesis, Gabriella Kalantar

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Chronic, low-grade systemic inflammation rises in obesity and promotes type 2 diabetes (T2D). Circulating immune cells are key indicators of obesity and T2D pathogenesis. T cells outnumber monocytes, in blood, suggesting that T cells might fuel peripheral inflammation in obesity/T2D. Our lab’s work supports this idea by identification of a Th17 cytokine profile in T2D from T-cell stimulated peripheral blood mononuclear cells. Work described herein further supported this work by demonstrating that T cells dominate peripheral inflammation over monocytes across the spectrum of obesity and glycemic control. Our lab has also recently shown that inflammation changes during prediabetes (preT2D), identified …

Substrate Selection And Effector Gating In The Helicobacter Pylori Cag Type Iv Secretion System, Mackenzie E. Ryan

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Helicobacter pylori is a recognized carcinogen and gastric colonization by strains that harbor the cag type IV secretion system (1) is the strongest known risk factor for stomach malignancy. Gastric adenocarcinoma is the fourth leading cause of cancer-related deaths world-wide ( > 700,000 deaths annually), with H. pylori directly contributing to the development of more than one million new cases of cancer per year accounting for 5.5% of all malignancies. H. pylori exploits cag T4SS activity to alter the mucosal microenvironment by delivering diverse immunostimulatory cargo into target gastric epithelial cells. Currently, the mechanisms by which the cag T4SS …
