White Guilt: An Ameliorative Proposal, William Moix
White Guilt: An Ameliorative Proposal, William Moix
Graduate Theses and Dissertations
Common in the philosophy of race literature – notably those centered on critiques of whiteness and the oppressive structures therein – we find that guilt is looked upon rather divisively. On one hand, representative of what I call the “abolitionist” position, we find that such states serve no function but to stifle progress towards social justice. Feeling such emotions in relation to one's race seems to lead necessarily to a retreat from the social endeavor of racial justice, resulting in selfish requests for absolution. On the other hand, representative of what I call the “proponent” position, we find prescriptions to …
Effects Of Land Cover And Land Change On Monarch Butterfly Presence Across The Conus, Chris R. Burkhart
Effects Of Land Cover And Land Change On Monarch Butterfly Presence Across The Conus, Chris R. Burkhart
Graduate Theses and Dissertations
The decline of monarch butterfly populations (Danaus plexippus L.) over the past four decades, particularly in their overwintering habitats, has raised concerns about the species' conservation. Habitat loss and modification, particularly within the contiguous United States, are attributed as one of the key drivers of this decline. However, the specific impact of land use and land cover (LULC) changes on monarch distributions remains inadequately documented. This study integrates monarch observations from multiple sources spanning 2008 to 2019 with LULC data to analyze the relationship between habitat configuration and monarch presence. Using a randomized grid sampling approach, habitat configuration metrics were …
‘Catching Zzz’S And Feelings’: A Study Examining The Link Between Sleep And Emotional Intimacy Among Sexual Assault Survivors, Anna Marie Thi Thanh Nguyen
‘Catching Zzz’S And Feelings’: A Study Examining The Link Between Sleep And Emotional Intimacy Among Sexual Assault Survivors, Anna Marie Thi Thanh Nguyen
Graduate Theses and Dissertations
The impact of sexual assault can be significant, including an increased likelihood of subsequent negative psychological and physical outcomes, even compared to other trauma types. Further studies indicate that individuals who have experienced sexual assault are more likely to struggle with interpersonal relationships. Sleep is a transdiagnostic process and disrupted sleep is a prominent feature of post-trauma related symptoms. Sleep is also implicated in social cognitive processes that are used to establish emotional intimacy in interpersonal relationships. The goal of the current study is therefore to examine the relations among sexual assault exposure, sleep, and emotional intimacy. A two-part study …
Influence Of Invasive Species, Drought, And Stream Permanence On Stream Crayfish Species With A Focus On The Imperiled Mammoth Spring Crayfish (Faxonius Marchandi), Leah Marie Bayer
Graduate Theses and Dissertations
Freshwater crayfish constitute one of the most-threatened taxonomic groups in North America. Invasion by other crayfish species as well as habitat degradation through alteration of natural flow regime are two of the most prominent threats to crayfish persistence. Additionally, extreme weather events like droughts can amplify threats posed by other stressors on crayfish populations and are expected to increase in frequency, magnitude, and/or duration in the future, which may negatively influence narrow-ranged endemic crayfish populations typical of the Southeast. The Mammoth Spring Crayfish, Faxonius marchandi, is a narrow-ranged endemic that occurs in the Spring River drainage of Arkansas and Missouri …
Moore’S Paradox, The First-Person, And Self-Knowledge, Matthew Warren
Moore’S Paradox, The First-Person, And Self-Knowledge, Matthew Warren
Graduate Theses and Dissertations
This thesis argues that Wittgenstein’s remarks on Moore’s paradox can be useful in resolving several debates concerning self-knowledge, particularly as that knowledge is manifested in avowals of belief, taking the form of sentences like “I believe that P”. Usually, sentences like these are taken to have a special first-person authority, epistemically privileged in comparison to their third-person counterparts ("He believes that P") and yet free from any reliance on evidence or observation in order to be made justifiably. It is also assumed that these avowals are functioning uniformly as reports on the speaker's mental state. Often, accounts of self-knowledge are …

Neural Interactions In Bottom-Up Communication, Prashant Chama Raju
Graduate Theses and Dissertations
The visual system’s remarkable ability to process vast amounts of sensory information rapidly and accurately is fundamental to cognitive neuroscience. This study investigates a key aspect of this capability: the compartmentalization of information into feature-specific subspaces during bottom-up communication. My primary question was: does Canonical Correlation Analysis (CCA) reveal a subspace that encodes color and direction of moving dot stimuli? I found that the first canonical component (CC1) does an excellent job decoding the stimuli, despite being one-dimensional while the stimuli were drawn from a two-dimensional space (red-green and up-down plane). I demonstrate that motion features are processed within distinct …

Evaluation Of A Capsule Suspension Formulation Of S-Metolachlor For Use In Fenclorim-Treated Rice And Wheat, Samuel Charles Noe
Graduate Theses and Dissertations
The continued evolution of herbicide resistance is one of the primary concerns facing Arkansas growers today. Problematic weeds such as barnyardgrass [Echinochloa crus-galli (L.) Beauv.] and Italian ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] have evolved resistance to some of the most used herbicides in rice (Oryza sativa L.) and wheat (Triticum aestivum L.). To counteract this resistance, alternative herbicide sites of action should be explored. S-metolachlor is a very-long-chain fatty acid (VLCFA)-inhibiting herbicide [Herbicide Resistance Action Committee (HRAC)/Weed Science Society of America (WSSA) Group 15] commonly used in U.S. row crops to control grasses and small-seeded broadleaf weeds. …

The Influence Of Commercial Salmonella Vaccination Programs On Local- And Systemic-Immune Responses And Ceca Microbiome In Egg-Type Chickens, Chrysta Noelle Beck
Graduate Theses and Dissertations
Salmonella vaccination is a widely accepted practice in the United States poultry industry. These vaccines stimulate a strong humoral response to Salmonella serovars and significantly reduce Salmonella load in the bird. In general, a Salmonella vaccination program for an egg-type pullet flock consists of two administrations of a live attenuated Salmonella vaccine at 1- and 6-wk-of-age followed by one administration of a Salmonella bacterin at 12-wk-of-age. Although these vaccines are regarded as effective against paratyphoid Salmonella infections, there are incidences of breakthrough Salmonella infections and severe injection site reactions after bacterin administration. Therefore, the main objective of this dissertation was …

Controls On The Development Of Hummocky Topography On Debris-Covered Glaciers, Ryan M. Strickland
Controls On The Development Of Hummocky Topography On Debris-Covered Glaciers, Ryan M. Strickland
Graduate Theses and Dissertations
Rock debris covers many glaciers in Earth’s highest mountains and the debris impacts glacier response to changes in climate. Interactions between debris, drainage, glacier dynamics, and climate produce contrasts in melt rates that cause debris-covered glaciers to develop complex, hummocky topography. Contrasts in melt rate produce thousands of hills–hummocks–and depressions. Ponds and ice cliffs often form in the depressions. Although ponds and ice cliffs occupy only a small fraction of the surface, they account for nearly half of glacier melt. Understanding the processes that control the development of hummocky topography is key to predicting the evolution of debris-covered glaciers. In …

This study investigated transparasocial relationships as they relate to identity management for content creators. Unlike traditional parasocial relationships, transparasocial relationships indicate high levels of interactivity between the creator and audience members. This study investigates how this interactivity affects the identity of the creators, specifically content creators on TikTok. A diverse set of 21 creators were reached out to and interviewed in a semi-structured respondent style over videoconference calls. Thematic analysis was conducted to discover how these creators are managing their identities within the context of their roles as content creators. A particular interest was taken to see if there were …
Assessment Of The Drivers Of Adoption Of Climate Smart Agriculture Practices Among Field Crop Farmers In Zambia, Faindani Nyirenda
Assessment Of The Drivers Of Adoption Of Climate Smart Agriculture Practices Among Field Crop Farmers In Zambia, Faindani Nyirenda
Graduate Theses and Dissertations
Climate smart agriculture (CSA) practiced has been promoted in Zambia since the 1980s to address the declining crop productivity due to increased occurrence of drought or dry spells caused by climate change. Despite considerable research indicating that CSA practices have many potential benefits such as increased yield and income, the adoption rate in southern Africa is still low especially where farmers have stable off farm income. This might be because most of the research and promotion has been directed to the main staple crop maize and other context specific impacts related to agroecological and socioeconomic heterogeneity. In this study we …
How Local Interactions Give Rise To Large-Scale Conformational Changes In Proteins: A Molecular Dynamics Study, Shadi A. Badiee
How Local Interactions Give Rise To Large-Scale Conformational Changes In Proteins: A Molecular Dynamics Study, Shadi A. Badiee
Graduate Theses and Dissertations
Proteins are dynamic entities that undergo conformational changes essential for their biological functions. These structural changes often correspond with chemical events such as lipid interactions or environmental changes like protonation or acidification. Understanding the complex relationship between these chemical perturbations and the resultant mechanical responses is crucial for elucidating protein mechanisms. This dissertation investigates the chemo-mechanical coupling in the conformational dynamics of the bacterial ABC transporter Sav1866 and the impact of protonation on the Influenza virus hemagglutinin HA0.

To Each Their Own: The Relationship Among Regret, Habits, And Academic Performance In College Students, Chandler Ann Findley
To Each Their Own: The Relationship Among Regret, Habits, And Academic Performance In College Students, Chandler Ann Findley
Graduate Theses and Dissertations
The extant literature on regret as motivation for behavior presents inconclusive results, collectively. While it has often been agreed that regret motivates reparative action, most studies from the past 14 years indicate that regret may motivate either detrimental actions or, more commonly, no action at all. There also appears to be no published research about college students’ academic regrets or how these regrets affect their classroom behaviors and performance. Therefore, this dissertation seeks to understand if college students regret their academic habits, what those habits are, and how their regrets and habits contribute to their academic performance over the course …
Measurement Reliability For Intentions To Change Behavior, Emily Schlichtig
Measurement Reliability For Intentions To Change Behavior, Emily Schlichtig
Graduate Theses and Dissertations
It is common for researchers to ask participants to associate probabilities with words, often using tools like the Likert scale to measure behavioral intentions and attitudes. However, it remains unclear what specific probabilities participants assign to the response options on a Likert scale, how much variation exists across these options, and whether these probabilities differ across various behaviors. The purpose of this paper is to explore the numeric probabilities that participants associate with different Likert scale points, to understand their perception of the variation at each point, and to compare these perceptions across three behaviors: eating more vegetables, exercising more, …
Investigation Of Optically Pumped Gesn Quantum Well Lasers, Grey Steven Abernathy
Investigation Of Optically Pumped Gesn Quantum Well Lasers, Grey Steven Abernathy
Graduate Theses and Dissertations
Silicon photonic integrated circuits enable the capability of producing on-chip processing of photonic signals, including both emission and detection. Emission materials, however, have been limited for monolithic integration due to high processing temperatures, indirect bandgap materials, and material integration complications. The (Si)GeSn material system has recently attracted attention due to the bandgap transition from the Si and Ge, naturally indirect bandgap, to direct bandgap with sufficient Sn incorporation. Additionally, the low growth temperature (CMOS compatible; <400 >°C) of (Si)GeSn materials can enable the monolithic integration of the highly desired mid-infrared light emission on the Si Photonic platform. This dissertation first discusses …
Tissue Engineered Models Of Environmental And Metabolism-Driven Cancer-Nerve Crosstalk, Emory Gregory
Tissue Engineered Models Of Environmental And Metabolism-Driven Cancer-Nerve Crosstalk, Emory Gregory
Graduate Theses and Dissertations
Purpose: Within the last 30 years, cancer-nerve interactions have garnered attention for causing patient pain, increasing the risk of recurrence, and decreasing patient prognosis. There are 2 key forms cancer-nerve crosstalk takes: perineural invasion (PNI), in which cancer cells infiltrate nerves as a route for metastasis, and tumor innervation (TI), in which neurites penetrate solid tumors to promote tumor progression. Present in vitro models of cancer-nerve crosstalk primarily include Matrigel® mouse matrix and collagen I hydrogels; whereas collagen I hydrogels neglect tumor extracellular matrix (ECM) complexity, Matrigel® is controversial for its batch-to-batch inconsistencies and inclusion of experiment-altering growth factors. Decellularized …
