Stories From Both Sides Of The Hedge: A History Of And Digital Exhibit For The National Hansen's Disease Museum, Laura Turner

Electronic Theses and Dissertations

The national leprosarium of the United States, located in Carville, Louisiana, started as the Louisiana Leper Home in 1894. Since Louisiana contained the largest endemic population in the contiguous United States of people suffering from leprosy, or Hansen’s disease as it would later be known, and maintained a successful institution dedicated to the care of such patients, the federal government purchased the leprosarium for national use in 1921. Although the national leprosarium was closed as a hospital in 1999, a small analog museum located on site preserves the history of the facility, the lives of the former patients, and tireless …

Effects Of Anthropogenic Light And Noise On Anuran Breeding Behavior, Ashley Kobisk

Electronic Theses and Dissertations

The natural environment can be negatively impacted by a variety of human activities, including the production of artificial light at night and anthropogenic noise. Recent studies suggest that pollution from anthropogenic light and noise alters animal behavior. Despite being highly nocturnal and vocal animals, little attention has been given to anurans and the effects artificial light at night and anthropogenic noise have on their behavior. This study investigated the effects of artificial light at night and anthropogenic noise on anuran breeding systems in eastern Texas. Specifically, this study investigated whether (1) artificial light and anthropogenic noise altered calling behavior in …

Simulation Of The Interaction Between Striated Muscle Unc-45 And Transcription Factor Gata-4, Drake Alexander Duncan

Electronic Theses and Dissertations

Striated Muscle UNC-45, also known as UNC-45b, is an important protein that acts as a chaperone for myosin in cardiac and skeletal muscles, binding to myosin at its C-terminal UCS domain and regulating its assembly into thick filaments and sarcomeric structures. The UCS domain contains a large loop that is believed to be the first point of interaction between myosin and UNC-45b. GATA-4 is an essential transcription factor that facilitates transcription of several genes in cardiac development, particularly alpha-heavy chain myosin in heart tissue. Recently, studies have shown that there is interaction of GATA-4 with UNC-45b and that GATA-4 binds …

Coherence, Travis Walthall

Electronic Theses and Dissertations

COHERENCE is a series of oil paintings and pen drawings that explores open narratives, or different ways to read artwork. The paintings and drawings showcase harmony, or tension, between ambiguous and representational forms. The visual experience requires the viewer to create their own narrative and decipher forms to do so. COHERENCE is a psychological and aesthetic exhibition fueled from human experience— one of fragility, uncertainty, imperfection, beauty, faith and memories.

Understanding And Avoiding Ai Failures: A Practical Guide., Robert Max C Williams

Electronic Theses and Dissertations

As AI technologies increase in capability and ubiquity, AI accidents are becoming more common. Based on normal accident theory, high reliability theory, and open systems theory, we create a framework for understanding the risks associated with AI applications. In addition, we also use AI safety principles to quantify the unique risks of increased intelligence and human-like qualities in AI. Together, these two fields give a more complete picture of the risks of contemporary AI. By focusing on system properties near accidents instead of seeking a root cause of accidents, we identify where attention should be paid to safety for current …

Photoassisted Synthesis Of Complex Polyheterocycles Via Rational Design Of Tailored Photoprecursors, Tina Alanna Holt

Electronic Theses and Dissertations

Natural products remain the most common source for drug leads, although diversity-oriented synthesis of unnatural complex molecules is gaining momentum. Our lab has been developing experimentally simple and straightforward approaches to complex molecular architectures via photochemical reactions involving a minimal number of experimental steps. In order to achieve this, photoprecursors were assembled via high yielding reactions. Next, we deployed photoinduced cycloadditions to create complex 3-dimentional structures. Lastly, with this obtained primary photoproduct, post-photochemical transformations were used to further grow its scaffold complexity.

One method to increase scaffold complexity is the [4+2] intramolecular cycloadditions of azaxylylenes, which are developed through standard …

Teachers Who Collaborate With A Professional Writing Organization: The Importance Of Critical Stance, Paul A. Viskanta

Electronic Theses and Dissertations

A wide body of research finds teacher preparation programs fail to address the complexity of writing instruction, especially for secondary English-language Arts teachers (Coker & Lewis, 2008; Graham, 2019; Wahleithner, 2018). Beliefs and knowledge about writing determine how teachers approach pedagogical practices (McCarthey & Mkhize, 2013). One of many contextualized social literacy practices, writing is always ideological (Gee, 2105; Moje & Lewis, 2007). Competing research philosophies complicate development of teachers' practices and impedes research dissemination (Coker & Lewis, 2008; Hillocks, 2008; National Writing Project & Nagin, 2006). Structures informing school-based writing limit the types of writing practices (Bazerman, 2016). Using …

The Role Of Dehumanization In The Nazi Era In Activating The Death Drive Resulting In Genocide, Stewart Gabel

Electronic Theses and Dissertations

Dehumanization can be defined in part as a process by which a powerful individual or group (the victimizers) actively denies or withdraws a second individual’s or group’s (the victim’s) sense of human worth or personal value. Dehumanization is an especially virulent form of denigration of the Other and is known to have harmful psychological consequences on victims.

The thesis of this dissertation is: Dehumanization, applied in an increasingly severe manner to demean, subjugate and control Jews in Nazi dominated territories during the Nazi era (1933-1945), activated a “death instinct/drive” (Freud 1920; 1923/1960; 1930) that was used to resolve an extreme …

Intellectual Property Rights In The Seed Industry: Barriers To Sustainable Agriculture, Elena A. Filatova

Electronic Theses and Dissertations

The dynamics of the dominant industrial agriculture system restrict the seed industry’s innovative landscape, leading to significant negative consequences including an exacerbation of environmental risks which threaten global food security. This thesis explores how exclusionary intellectual property rights (IPRs) in the context of the seed industry constrict innovation, evolutionary pathways, and opportunities for the implementation of sustainable agriculture methods. To overcome these barriers, the application of an open source framework to seed innovation, specifically through the platform of the Open Source Seed Initiative, is evaluated as a tool for enhancing innovative capacities in seed development while broadening the accessibility and …

Observation Of New Particle Formation In The Northern Hemisphere At Altitude From 4 To 20 Km, Mohamed Saad

Electronic Theses and Dissertations

New particle formation (NPF) is investigated using measurements of aerosol size distributions and meteorological variables made in two continents, including USA and Europe. Despite the considerably different aerosol particle abundances among the sites, a common relationship was found between the characteristics of NPF events and the air mass convective and/or advective transport. CO and O3 act as tracers of tropospheric and stratospheric air, respectively, their statistical relationship can be used to quantify air mass characteristics and origins. The mixing ratio values of CO increased within the upper troposphere layer before/during NPF events, which may serve as an indicator of occurring …

Coming Together Over Table: The Role Of Food In Georgian Conflict Resolution Practices, Raisa Wells

Electronic Theses and Dissertations

Conflict resolution efforts seek to de-escalate conflict dynamics to bring conciliation and/or reconciliation to a conflict. One strategy to de-escalate a conflict is to use food during conflict resolution efforts. So, what specifically does consuming food and beverage do to break down conflict escalation cycles? Food-sharing brings several aspects to conflict that the literature suggests address how and why conflict escalates. This paper focuses on three prevalent aspects: how food-sharing signals vulnerability and trust building, perceived commonality, and a change in the conflict from competition to cooperation by providing new norms, changing the tone, and shifting frames. Because of the …

The Essence Of Reincarnation And Consciousness As A Gateway Into Teaching And Learning, C. Capucine Chapman

Electronic Theses and Dissertations

This phenomenological study explores the essence of ancestral knowledge from a belief in reincarnation and consciousness, as it relates to the lived experiences of diverse educational professionals, and its contribution to their growth and development. The study investigates the lived experiences of adult educators from four distinct teaching and learning environments: applied metaphysics, Buddhism, anthroposophy, and Indigenous. All participants maintain a practicing belief in reincarnation, consciousness, and ancient and/or esoteric knowledge. The present study sought to understand how this knowledge influenced and impacted educator growth and development, and examined overlaps in teaching and learning.

Maternal Hpa Axis Function During Parenting Is Associated With Reduced Brain Activation To Infant Cry And More Intrusive Parenting Behavior, Andrew Erhart

Electronic Theses and Dissertations

Previous research indicated that maternal cortisol function and maternal brain response to infant stimuli are separately related to differences in parenting behavior. Evidence from animal models have demonstrated that chronically high cortisol concentration alters brain structure and function, suggesting that studying these two mechanisms together may further improve understanding of parental behavior in human mothers. First time mothers of infants aged 1-7 months old (M age = 3 months) were recruited to participate. Mother’s cortisol concentration was measured during a naturalistic interaction with their infant and their behavior was coded for maternal sensitivity and nonintrusiveness. In a separate session using …

Fatty Fatty Two-By-Four—Can’T Get Through The Dressing Room Door?: An Examination Of Excess As Queer Failure, Miranda Dottie Olzman

Electronic Theses and Dissertations

Failure and fat are not linear. It is taught, learned, reminded, and internalized. Our bodies have memories that are built through repeated moments. And for me, failure has been a part of my body’s map since I was born. This project is the culmination of many failures. In this dissertation, I am examining queer failure in multiple contexts including body size, as well as religion to create a corpulent critique. I do this by examining the lineage of queer failure as well as queer temporality as it is linked to failure (Edelman; Muñoz; Halberstam; Love) with fat queer bodies serving …

Validation Of A Deployable Proteomic Assay For The Serological Screening Of Sexual Assault Samples, Catherine O'Sullivan Brown

Electronic Theses and Dissertations

Protein mass spectrometry (MS) has emerged as a technique to supplant traditional serological tests for body fluid identification. It was hypothesized that proteomic techniques would surpass the sensitivity and specificity of traditional serological techniques. An automated workflow coupled with protein MS has been developed for the confirmatory identification of five biological fluids. A developmental validation was completed, assessing parameters such as reproducibility, sensitivity, ion suppression, and limit of detection. Implementation was determined through tandem sample processing by MS, traditional serological tests, and standard DNA profiling methods. The MS approach offered superior detection limits while also providing true confirmatory results, producing …

Preconception Stress, Affect-Biased Attention, And Negative Affectivity: Assessing Pathways And Early Markers Of Psychopathological Risk In Infancy And Childhood, Danielle A. Swales

Electronic Theses and Dissertations

The developmental origins of mental health likely begin early in life and perhaps even prior to conception. Research is needed to elucidate pathways of risk and resilience in the development of psychopathology. The goal of the current dissertation was to explore how both preconception and postnatal experiences influence negative affectivity, a robust and transdiagnostic risk factor for later psychiatric symptoms. The present dissertation accomplished this goal by completing two independent studies, each of which are presented in the format of standalone journal articles. Study one focused on evaluating how preconception experiences, specifically maternal symptoms of post-traumatic stress disorder (PTSD), impact …

Airbnb Release Of Latent Economic Value And Return To Equilibrium, Daniel Joseph Trujillo

Electronic Theses and Dissertations

We empirically consider Airbnb’s effect on a new variable in Short Term Rental (STR) research, second homes, employing a model pre-Airbnb diffusion (2009), and post-Airbnb diffusion (2019). In doing so we test our hypothesis that second home use will be converted to short-term rentals with the advent of Airbnb. We do so through a natural experiment examining housing stock. We create a schema to segregate tourist and non-tourist counties based on economic variables and deploy these in our research framework observing a shock to housing supply. Notably, we observe a structural change in the use of second homes resulting in …

Lawthy: Holding Flowers, Bailey Pittenger

Electronic Theses and Dissertations

The research and design of this dissertation involves four parts: 1) Bridges to Care Work in the Sick Room, an essay that begins bridges across care genealogies, foundational literature on nursing and sick rooms, and applications of care work and care logic via local protest, civic, and community engagements; 2) “Writing Lawthy,” which is a process-based approach to literary and social sciences research on “writing on memory loss” and dementia narratives that center personhood and autonomy; 3) Lawthy: Holding Flowers, a fragmented novel created by first-hand accounts of caregiving, a 1981 journal, and fiction; and 4) appendices of local city …

The Orient In The Empire’S Poetry: Scholarship, Translation, And Imaginative Geography (1770-1857), Zeeshan Riyaz Reshamwala

Electronic Theses and Dissertations

This dissertation uses the idea of imaginative geography to study literary and scholarly representations of what writers in Europe referred to as the Orient during the long nineteenth century. Imaginative geography refers to a subjective collection of associations that accumulate around a place about which positive knowledge is limited, such that the imaginative associations overpower and structure any empirical knowledge about it, even when further knowledge is acquired. The imaginative geography of the Orient emerged from texts, images, and artifacts that traveled from Asia to Europe through sustained colonial contact. This dissertation studies how writers in India and Britain constituted, …

Remembering Together: Native Boarding School Stories On Display, Lydia Nancy Wood

Electronic Theses and Dissertations

Recent scholarship on Native American boarding schools has focused on drawing out the complexities of boarding school history and emphasizing the plurality of experiences of students. This thesis examines how Native American boarding school stories have been displayed using two current museum exhibits: “Away from Home: American Indian Boarding School Stories” at the Heard Museum, and the Phoenix Indian School Visitors Center, a small gallery in one of the remaining school buildings. For this analysis I interviewed key players in both current exhibits and did close readings of the exhibits themselves, in conjunction with archival research about two model schoolhouse …

Community Unclaimed: Plurality And The Problem Of Sovereignty In Bataille, Nancy, And Blanchot, Gregory J. Grobmeier

Electronic Theses and Dissertations

This dissertation takes up the exchange between three prominent French thinkers on the question of “community”: Georges Bataille, Jean-Luc Nancy, and Maurice Blanchot. Taken together, and starting with Bataille’s prewar writings and communitarian activism in the 1930s, the exchange between them now spans nearly a century. Georges Bataille’s importance as a political thinker and writer was brought out of relative obscurity with the publication of Jean-Luc Nancy’s “La Communauté désoeuvrée” in 1983. Less than a year after the appearance of Nancy’s inaugural essay, Maurice Blanchot, a close friend of the late Bataille, published La Communauté inavouable. Blanchot’s text was …

The Martyr’S Desire: Levinas, Girard, And Infinite Responsibility, Joshua Alan Lawrence

Electronic Theses and Dissertations

Perhaps the whole of human history could be summed up with one word: economy. The law of the home and the home of all law. Without fail, this situation results in a structured devotion that must decide what to do with desire. And the economic decision often follows a violent trajectory, most commonly described as sacrifice. Today, states will make efforts to conceal this underlying logic, but the insidious configurations of ‘real politik’ usually surface with a frightening intensity.

My project considers these problematic vestiges through Emmanuel Levinas’s reconfiguration of subjectivity. To address these bio-historical realities, my work highlights the …

Plantation Economy Model As Developed By Lloyd Best And Kari Polanyi Levitt: The Case Of Jamaica, Paula-Leone Samuda

Electronic Theses and Dissertations

Lloyd Best and Kari Polanyi Levitt created the Theory of the Plantation Economy as an analytical tool for understanding the causes of underdevelopment in the Caribbean region. The theory provides a break from the classical understanding of developing economies as simply pre-industrialized societies. Instead, the theory tracks uneven development through analysis of metropole-hinterland relations, which account for the legacy of slavery, colonialism, and mercantilism on the structure of the global economy. In doing so, Plantation Theory is able to draw a clear link between underdevelopment in the hinterland and development in the metropole. Examining the usefulness of the Theory of …

The Role Of Vps54 In Drosophila Melanogaster Neuronal Development And Age Progressive Neurodegeneration, Emily Wilkinson

Electronic Theses and Dissertations

Vps54 is a subunit of the Golgi-associated retrograde protein (GARP) complex, which is involved in tethering endosome-derived vesicles to the trans-Golgi network (TGN). The “wobbler” mouse is the phenotypic result of a destabilizing point mutation in Vps54. This mutation causes neurodegeneration and is subsequently used as a model for human motor neuron disease. Presently, it is unclear how disruption of GARP complex function leads to motor neuron degeneration. To better understand the role of Vps54 in motor neuron development, function, and age-related neurodegeneration, we disrupted expression of the Vps54 ortholog in Drosophila and examined the impact on larval neuromuscular junction …

Undergraduate Teaching Excellence Through The Aesthetic Lens Of Crispa, Paula Adamo

Electronic Theses and Dissertations

In times where only 60% of college students are graduating (NECS, 2018), the need to help undergraduates thrive in college is vital. Because faculty have a crucial role in this profound endeavor, this study examines the intentions (intentional curriculum) of four undergraduate instructors identified by colleagues and students as good teachers. The study also examines what students take away from their instructors and classes (received curriculum) and looks at how elements of the aesthetic approach to teaching and learning known as CRISPA emerge naturally in the curricula in order to demonstrate the proposition that good teachers, at any level, implement …

Surface And Interfacial Phenomena Between Soil And Oil, Md Firoz Ahmed

Electronic Theses and Dissertations

Crude oil and motor oil spills on land have severe environmental consequences that pose threats to both humans and natural resources. It is particularly important to know the flow behavior of oils to protect terrestrial ecosystems from this kind of damage. The spreading kinetics, contact angle (CA), and droplet baseline studies of crude oil and motor oils were investigated over several realistic soil-based matrices composed of topsoil (silt-dominant), sand, clay, and moisture. It was found that with an increase in moisture content (MC), the spreading area decreased, and initial spreading time increased for all given oil. The initial CA generally …

Dependency-Based Reactive Change Propagation Design Pattern Applied To Environments With High Unpredictability, João Paulo Oliveira Marum

Electronic Theses and Dissertations

Transitional turbulence is a period of chaotic or unreliable variation in the state of a software system that results from changes in the system’s interconnected components. During these periods of instability, an external observer of the system’s state may “see” erroneous results. This is a problem that can affect visual user interfaces such as those in virtual and augmented reality applications and desktop or Web GUIs. In this research, we study two different reactive applications developed in C# on .NET. We reduce the transitional turbulence by augmenting the base applications with a dependency-graph-based event scheduling approach. The first study investigates …

Management And Dietary Strategies To Mitigate Environmental Stressors In Northern Plains Cattle Feeding Systems, Warren Carl Rusche

Electronic Theses and Dissertations

Three studies were undertaken to examine strategies to mitigate environmental stress faced by Northern Plains cattle feeders. In the first study, 46 feedlot managers from SD (n = 21), MN (n = 6), and NE (n = 19) were surveyed on use and perceptions of heat stress (HS) mitigation strategies. All respondents avoided cattle handling during heat stress events and incorporated some method of HS mitigation. Buildings or shades were perceived as the most successful strategy (60.9%) and were most commonly named as strategies managers would like to employ (63% for shades and 17.4% for buildings). Increasing dietary corn silage …

Identification Of Loci Influencing Teosinte Crossing Barrier 1 (Tcb1) Efficacy In Maize By Quantitative Trait Loci (Qtl) Mapping And Genome-Wide Association Study (Gwas), Namrata Maharjan

Electronic Theses and Dissertations

Pollen cross-contamination has been a major problem for maize breeders. Various mechanical methods applied to avoid the contaminations are ineffective. The genetic factors related to maize fertilization can be used to develop an effective method to prevent pollen contamination. Pollen rejection ability controlled by Teosinte crossing barrier 1 (Tcb1) is such a genetic system. Silks possessing dominant Tcb1-s reject pollen possessing the recessive allele (tcb1). Successful fertilization occurs when Tcb1-s pollen falls upon tcb1 silks. The efficacy of dominant Tcb1-s was, however, reduced when repeatedly backcross with maize inbred lines, which suggests that there are modifiers to Tcb1-s. To find …

Pollinator Ecology In Agroecosystems Of Eastern South Dakota, Isabela Beatriz Vilella-Arnizaut

Electronic Theses and Dissertations

Community structure contributes to ecosystem persistence and stability. To understand the mechanisms underlying pollination and community stability of natural areas in a human influenced landscape, a better understanding of the interaction patterns between plants and pollinators in disturbed landscapes is needed. Furthermore, understanding the potential conservation value in green spaces such as botanical gardens could assist in preserving and bolstering plant-pollinator interactions. Our study takes place in the Northern Great Plains which still retains extensive tracts of remnant temperate grassland habitat within a matrix of varying land-uses. First, we used a network-based approach to quantify how temperate grassland attributes and …
