Three Essays On Consumption Smoothing, Logan James Miller

Graduate Theses and Dissertations

Macroeconomic theory has established that consumption smoothing leads to higher standards of living. A stable consumption path can lead to more stability and less uncertainty between periods of high and low income. However, there is a wide body of literature that shows people do not consistently smooth their consumption when exposed to adverse income shocks. This dissertation uses experimental and empirical methods to better understand the obstacles people face when trying to smooth their consumption over time. It looks to understand the differences in pairs and individuals’ ability to smooth consumption. It also explores how the household’s level of income …

Does The Financial Experience Of Sec Regional Directors Impact Sec Investigations Into Reporting Entities?, James Justin Blann

Graduate Theses and Dissertations

The SEC’s Division of Enforcement is frequently criticized for its lack of oversight effectiveness, and certain vocal critics attribute this to a lack of financial experience within the SEC. Using hand-collected data on SEC regional directors, I find that the majority of these SEC officials lack financial experience. I then examine whether the financial experience of SEC regional directors impacts SEC investigations into reporting entities. Consistent with financial experience equipping directors to better process complex financial transactions and reports, I find that directors with financial experience open public company investigations 29 percent more often and conduct these investigations 34 percent …

Beyond Nutrition: Three Essays On The Effects Of Food Processing And Sustainability Labeling On Consumer Perceptions And Evaluations, Garrett J. Rybak

Graduate Theses and Dissertations

Recent consumer trends reveal increasing demand for greater product transparency including how products are processed, the types of ingredients used, and the impact on the environment. As a result, food marketers often use a combination of processing, nutrient content, and/or sustainability claims to convey specific information to consumers. Considering these developments, several questions arise about how these claims affect consumer evaluations of healthfulness, sustainability, disease risk, and intent to purchase while considering the unregulated and regulated nature of many of these claims.

In Essay One, we extend our understanding of consumer responses to package claims by comparing the direct and …

Study Of Single-Photon Wave-Packets With Atomically Thin Nonlinear Mirrors, Christopher Klenke

Graduate Theses and Dissertations

A novel controlled phase gate for photonic quantum computing is proposed by exploiting the powerful nonlinear optical responses of atomically thin transition metal dichalcogenides (TMDs) and it is shown that such a gate could elicit a π-rad phase shift in the outgoing electric field only in the case of two incident photons and no other cases. Firstly, the motivation for such a gate is developed and then the implementation of monolayer TMDs is presented as a solution to previous realization challenges. The single-mode case of incident photons upon a TMD is derived and is then used to constrain the more …

Reconciling Conflicting Institutional Logics: Community Reinvestment Officers At The Intersection Of Public Policy And Market Forces, Meredith Mckee Adkins

Graduate Theses and Dissertations

Although the public policy literature has traditionally focused on public sector agencies’ roles in the policy implementation process, private sector managers who oversee regulatory mandates for their organizations are also policy actors. These actors operate between multiple conflicting field-level institutional logics that create demands that they must reconcile through their work. In the banking sector, the Community Reinvestment Act (CRA), enacted in 1977, and its associated policies are monitored by the banking regulatory agencies and implemented by the senior managers responsible for these mandates at regulated financial institutions. Simultaneously with their responsibility for the policy mission of the CRA, CRA …

The creation of web-based real-time computer simulations has given language educators incredible new opportunities to create immersive experiences for English as a Foreign Language (EFL) learners. This thesis reviewed 12 empirical studies, 3 previous literature reviews, 3 non-empirical journal articles, and 23 additional background sources investigating the impact of Immersive Virtual Environments (IVE) on EFL learners’ motivation and oral communication in EFL learning. 12 empirical studies were analyzed closely while other sources were used to provide additional information and theoretical insights. The findings indicate that IVEs offer novel ways to connect EFL learners to native-speaking communities where they can acquire …

Evaluating Flavor And Aroma Attributes Of Arkansas-Grown Horticultural Crops, Jordan Chenier

Graduate Theses and Dissertations

Arkansas has a climate and geography that allows for the production of unique horticultural crops, including hops (Humulus lupulus L.), blackberries (Rubus subgenus Rubus), and muscadine grapes (Vitis rotundifolia). These crops not only have potential for growers in Arkansas but have unique flavor and aroma attributes that impact marketability. Volatile compounds present in many different agricultural plants are the primary source of biologically-derived aromas and flavors. Therefore, the volatile and other quality attributes of hops, blackberries, and muscadine grapes were evaluated at the University of Arkansas (UA System) Division of Agriculture. The quality, volatile, and sensory attributes of four hops …

Diversity, Equity, And Inclusion: Three Essays In The Educational Context, James D. Paul

Graduate Theses and Dissertations

Many universities and K-12 public school systems express a significant, formal commitment to the ideals of diversity, equity, and inclusion (DEI). Relative to the emphasis on DEI in America’s educational institutions, however, there has been little research describing DEI trends and evaluating the efficacy of DEI bureaucracies. This three-chapter dissertation examines DEI trends that have been the subject of much discussion—but rarely studied empirically.

For example, chapter one analyzes how universities promote DEI when hiring new faculty. I audit a subset of academic job postings and present the first evidence on how many require DEI statements, as well as the …

Expression Of Claudins In Gill And Opercular Membranes In Relation To Osmoregulation In Euryhaline Atlantic Killifish, Fundulus Heteroclitus, Allison Mcfarland

Graduate Theses and Dissertations

Atlantic killifish (Fundulus heteroclitus) are euryhaline teleosts, which means they can thrive in environments with varying salinities, ranging from concentrated seawater (SW) to dilute fresh water (FW) and thus survive in estuaries. To be able to maintain ionic and osmotic homeostasis in these diverse salinities, osmoregulatory organs like gill and opercular membrane must be able to adjust the permeability and transport of water and ions. The surface epithelia in these organs need to prevent the passive flux of ions and water in a drastically changing environment, while being able to switch between active ion secretion or uptake dependent upon environmental …

Rodent Dental Microwear Texture Analysis As A Proxy For Fine-Scale Paleoenvironment Reconstruction, Jenny H. E. Burgman

Graduate Theses and Dissertations

Dental microwear texture analysis (DMTA) of fossil fauna has become a valuable tool for dietary inference and paleoenvironment reconstruction. Most of this work has utilized larger taxa with larger home ranges. These studies may result in broader-scale habitat inferences that could mask the details of complex mosaic habitats. Rodent DMTA offers an opportunity to work at finer spatial scales because most species have smaller home ranges. Rodents are also keystone species within their ecosystems, abundant, ubiquitous, and found in many fossil deposits. These attributes make them excellent proxies for environmental reconstructions. However, the application of DMTA to rodents remains relatively …

Temporal Changes In Surface Water Availability: Patterns Of Seasonal Shift On Water Stress In The Conterminous Us Under A Changing Climate, Quinn Montana

Graduate Theses and Dissertations

The argument could be made that there is nothing more valuable on the planet than water. Our lives depend upon it. Climate change is already having an impact on the United States (US) and water stress will be one of the problems we increasingly face in coming decades. Regional research has shown that one or another part of the conterminous US (CONUS) is expected to experience an annual deficit or a surplus in runoff. Further studies have looked at changing patterns over the CONUS as a whole. Other research has focused on a particular season. This work addresses a gap …

A Boy Born On Wednesday, Charles Krampah

Graduate Theses and Dissertations

My relocation to America has presented an unprecedented space for self-examination. The components of my identity and personality have been laid bare before me; My blackness in the face of racism and white hegemony, my African heritage in the face of post-colonialism and imperialism, and my faith in the face of an increasingly secular western culture.

Am I who thought I was? Am I more or less? Why do I feel like a different person, and what does this mean for my future?

My research and art practice serve as a form of introspection. I tell an internal story in …

As The Sun Yellows The Green Of The Maple Tree, Adam Fulwiler

Graduate Theses and Dissertations

As the Sun Yellows the Green of the Maple Tree is a body of paintings investigating communication, improvisation, play, and painting’s capacity for transformation.

Reflecting on my childhood spent with my brother, Austin, who experiences sensory differences due to autism, I establish a painted space that is both forcibly disjointed and meaningfully connected, invoking the uncertainty and complexity of perception and communication. Through chromatic nuance, physicality, representational ambiguity, and visual tempo, I invite the viewer into the act of slow looking—to encounter each work as a living, breathing, individual entity.

In the studio, I invent rules and aleatoric devices, mimicking …

Boring Magic, Madison Svendgard

Graduate Theses and Dissertations

Boring Magic encompasses an interest in labor, boredom, and exhaustion. Simultaneously, I am exploring what relief and escapism from these things look like. Escapism acts as the core of my work- what escapism looks like and what creates the need for escapism. I create narrative pieces that are always slightly removed from reality as a way to reflect on what I view as present-day dystopias. The worlds built to create this work are a combination of my lived experiences and invented characters and stories, which culminate in an alternate timeline set in the late 1990s and early 2000s. Relating to …

An Investigation Of Factors Affecting The Rooting Ability Of Hardwood Muscadine Cuttings And Genetic Diversity Of Wild And Cultivated Muscadine Grapes (Vitis Rotundifolia Michx.), Kenneth Buck

Graduate Theses and Dissertations

The muscadine (Vitis rotundifolia syn. Muscadinia rotundifolia) is a grape species native to the southeastern United States. Muscadines are one of three grape species in subgenus Muscadinia with a chromosome number of 2n=40 (V. rotundifolia, V. munsoniana, and V. popenoei), making them genetically distinct from the European wine and table grape (Vitis vinifera) and other species in subgenus Euvitis. Rooting hardwood cuttings from muscadine vines has traditionally been considered an exceptionally difficult task. Many previous studies observed almost no root formation, leading to a general consensus that muscadines should either be propagated by softwood cuttings or vegetative layering. However, the …

Hallucinogenic Neoshamanism As Antimodernism: Development And Ethical Considerations, Ethan Thompson

Graduate Theses and Dissertations

Humans have been using hallucinogenic plants and fungi for thousands of years. Historically, people around the world have made use of these substances to aid in their spiritual development. Studies of the usage of hallucinogens in indigenous societies often use the term “shamanism” to characterize the associated system of belief and ritual practices. In popular understanding, shamanism is a religious system that features highly ritualized performances in which a practitioner (shaman) utilizes an altered state of consciousness to gain access to realms inhabited by spirits with the intent of recruiting their help to resolve a problem, cure a patient, correct …

How Nonbinary College Students At Southern Universities Explore Identity Through Gender Expression, Charles Jesse Thompson

Graduate Theses and Dissertations

As the number of young people identifying as nonbinary continues to increase (Davis, 2018), our need, as educators, to understand their experiences on college campuses also increases. Using narrative inquiry and photovoice, framed by critical queer theory and genderism, this examined both institutionalized and socially constructed expectations and influences that affect the development of nonbinary gender expression and identity for the college students by addressing the research question: What are the experiences of nonbinary college students in the Southern United States in exploring their gender expression at research universities? The five major themes that emerged from this study were as …

The Effect Of Tier 2 Intervention On Student Achievement & Student Self-Efficacy, Cheyenne Morgan Hill

Graduate Theses and Dissertations

Biology is a key course in a student's learning path. It provides important information about the living world and creates foundational knowledge that will be used in other science courses as the student progresses through his or her secondary and post-secondary education. However, there is a pattern of low student achievement in this required science course. The inability for students to understand and retain the curriculum in turn leads to low self-efficacy. Together, this creates a poor attitude toward science and a reluctance to pursue further science courses and in turn science careers. Response to Intervention (RTI), a common educational …

“All Skinfolk Ain’T Kinfolk”: Attributions Of Race-Based Discrimination When An Ingroup Member Is The Perpetrator, Christin Alexandra Mujica

Graduate Theses and Dissertations

Most research addressing racial/ethnic discrimination is focused on instances perpetrated by White people or someone not of the same race or ethnic background as the target (i.e., outgroup discrimination). However, based on theories of ethnic identity development and internalized racism, it is possible for people of color to discriminate against people in their own racial or ethnic group. The current study used a qualitative approach to 1) understand what people of color believe about racism and discrimination broadly and based on the race of the perpetrator, 2) describe under what situations (e.g., race of perpetrator or overtness/subtlety of the act) …

Posterior Predictive Model Checking Of The Hierarchical Rater Model, Nnamdi Chika Ezike

Graduate Theses and Dissertations

Fitting wrongly specified models to observed data may lead to invalid inferences about the model parameters of interest. The current study investigated the performance of the posterior predictive model checking (PPMC) approach in detecting model-data misfit of the hierarchical rater model (HRM). The HRM is a rater-mediated model that incorporates components of the polytomous item response theory (IRT) model, such as the partial credit model (PCM) and generalized partial credit model (GPCM), at the second level of the hierarchy, to model examinees’ responses to performance assessments. To date, the HRM has not been rigorously evaluated using PPMC techniques. Monte Carlo …

Evaluation Of Fenclorim Safener For Use In Rice With Group 15 Herbicides, Tristen Heath Avent

Graduate Theses and Dissertations

The development of herbicide resistance and the lack of effective herbicides to control problematic weeds has caused Arkansas rice (Oryza sativa L.) production to pursue alternative sites of action. Currently, very long-chain fatty acid elongase inhibitors are not labeled for U.S. rice production but have been widely used for Asian rice production systems. Previous research has demonstrated the utility of acetochlor and pyroxasulfone to provide in-season weed control for Arkansas rice production, but variable crop tolerance has been observed. Additionally, acetochlor at 1,260 g ai ha-1 elicited less rice injury when seeds were treated with a herbicide safener seed treatment …

A Geochemical And Mineralogical Evaluation Of The Mona Lisa Turquoise Mine, Polk County, Arkansas, Alexander Arai Goodsuhm

Graduate Theses and Dissertations

The presence of turquoise in Arkansas has long been disputed by geologists and gem collectors. Despite the prevalence of other phosphate minerals in Arkansas, such as planerite, wavellite, and variscite, the absence of an obvious copper (Cu) source required for turquoise formation was considered too great of an obstacle for turquoise mineralization. In this study, geologic, mineralogical, and geochemical techniques provide overwhelming evidence that the novaculite-hosted Mona Lisa Mine in Arkansas does produce turquoise. X-ray diffraction and Raman spectroscopy have confirmed the structural nature of the material and identified other phosphate minerals, such as crandallite, often found in assemblage with …

To The Window, To The Wall: Improving Environmental Monitoring Protocols, Sarah Jones

Graduate Theses and Dissertations

Detecting microorganisms on environmental surfaces via an environmental monitoring (EM) program is part of a preventive food safety culture. Environmental monitoring should 1) verify that food safety plans are reducing cross-contamination risk from surfaces to food, 2) pinpoint microbial niches, and 3) prevent the transmission of pathogens. Environmental monitoring programs utilize EM tools, such as sponges, to sample food contact and non-food contact surfaces. However, EM tool selection is determined by the individual food firm. This dissertation evaluated and characterized factors influencing EM program effectiveness in the food industry. Specifically, this dissertation focuses on the release of microorganisms from EM …
