Altering the Distance

Brandon Reinkensmeyer
Distancing—a cognitive reappraisal strategy—increases conciliatory policy support (i.e., policies redressing inequity) by reducing anger. Related but distinct research has used construal level theory (CLT), which explains the relationship between psychological distance and mental representations (e.g., events and attitudes), to explore intergroup relations. CLT demonstrates increased psychological distance induces abstract thinking, which leads to high-level construal (HLC) mindsets. HLC mindsets, like distancing, decrease political polarization and prejudice toward out-groups. As both distancing (an appraisal technique) and...

MAGNETIZATION DYNAMICS IN A MODIFIED SQUARE ARTIFICIAL SPIN ICE

Amrit P. Kaphle
Artificial spin ices are magnetic metamaterials consisting of nanomagnet arrays in a 2-D lattice. Typically, these nanomagnet arrays are binary macrospins that can only be in an up or down state similar to the Ising spins. They have been intensively used to study magnetic frustration and ordering phenomena in a controlled environment. The hexagonal artificial spin ice and square artificial spin ice are among the most heavily studied systems. In this dissertation, we designed a...

APOE GENOTYPE AND CEREBRAL GLUCOSE METABOLISM

Holden Williams
Apolipoprotein E (APOE) is encoded by the APOE gene, present in humans as three main isoforms (E2, E3, and E4). E4 carriers face up to a 15-fold increased risk for developing late-onset Alzheimer’s disease (AD), while E2 carriers are protected. Understanding the risk conferred by E4 has been an extensive research focus for nearly three decades, but the exact mechanism has yet to be proven. Many studies have demonstrated attenuated roles of E4 in classical...

SYNTHESIS OF 6,6- AND 7,7-DIFLUORO-1-ACETAMIDOPYRROLIZIDINES AND THEIR OXIDATION CATALYZED BY THE NONHEME Fe OXYGENASE LolO

Nabin Panth
One of the remarkable steps in loline alkaloid biosynthesis is the installation of an ether bridge between two unactivated C atoms in 1-exo-acetamidopyrrolizidine (AcAP). LolO, a 2-oxoglutarate-dependent nonheme Fe oxygenase, catalyzes both the hydroxylation of AcAP and the resulting alcohol's cycloetherification to give N-acetylnornoline (NANL). The mechanism of hydroxylation is well understood, but the mechanism of the oxacyclization is not. I synthesized difluorinated analogs of AcAP in an attempt to further understand the mechanism of...

A CORPUS STUDY OF THE DEVELOPMENT OF THE ADJECTIVE PHRASE IN FRENCH CHILDREN

Avery Elizabeth Baggett
In this thesis I attempt to answer three questions: H1) Do children use proportionally more prenominal or post-nominal placement of adjectives than adults? H2) Are children more conservative or more creative in their behavior in alternating prenominal and post-nominal placement of adjectives? H3) If colored terms are more frequent in child speech will they pattern more like prenominal adjectives or more like post nominal adjectives, as in adult speech? To do this, I examine two...

Reproductive Diapause in the Ladybird Beetle Cycloneda munda

John Obrycki
Adult Cycloneda munda were collected from Fayette County, Kentucky (38.12°N, 84.54°W). Eggs were collected daily from 4 to 6 females and placed in L:D 16:8, 14:10, 12:12,10:14, at 22°C ± 1.0°C. F1 offspring were individually reared in glass vials at each photoperiod on pea aphids and Ephestia kuehniella eggs to examine the effects of photoperiod on development (Data file 1: C-munda-Dev-Times-at-LD.jmp). Comparisons of the developmental responses to the four LD treatments were made. Pairs of...

Numerical Investigation of an Oxyacetylene Torch With Regards to an Ablative Material

Luke Fortner
A computational fluid dynamic (CFD) software is used to model an oxyacetylene torch used as a screening facility for high temperature material testing. First, a published test-case is used to verify the CFD approach. The model that was produced falls within 5% of the Marra et al. [15] work in regards to heat flux and front face temperature, with a one step reaction mechanism that is computationally cheap. Then, the approach is used to model...

An Electrochemical, Fluidic, Chip-Based Biosensor for Biomarker Detection

Lauren Bell
Biosensors and their use in both the research and clinical field for the detection and monitoring of critical biomarkers are prevalent and constantly improving. However, continued research needs to be done to address shortcomings, such as low sensitivity, poor specificity, and poor readiness for integration into research use and patient care. The objective of this research was to create a combined fluidic, chip-based biosensor that could detect different biomarkers with high sensitivity and ease of...

\"IT'S NOT RAINBOWS AND UNICORNS\"

Hugh Deaner
This dissertation examines the regulated oilsands mining industry of Alberta, Canada, widely considered the world’s largest surface mining project. The industrial processes of oilsands mining produce well over one million barrels of petroleum commodities daily, plus even larger quantities of airborne and semisolid waste. The project argues for a critical account of production concretized in the co-constitutional relations of obdurate materiality and labor activity within a framework of regulated petro-capitalism. This pursuit requires multiple methods...

ATTENTIONAL BIAS, INHIBITORY CONTROL, AND FOOD REINFORCEMENT AS MECHANISMS PROMOTING EATING BEHAVIOR AFTER EXERCISE

Kylie F. McFee
Background: Excess weight and obesity are serious health conditions characterized by modifiable and nonmodifiable risk factors. Exercise is a common method for achieving weight loss; however, results are not always achieved due to post-exercise compensatory behaviors. Increased energy intake (EI) is thought to be the main compensatory behavior hindering weight loss among overweight and obese adults. It is important to determine and understand the mechanisms behind energy compensation following exercise, as this will allow for...

Elephants in the Room

Helen Richardson
The COVID-19 pandemic brought forth unprecedented and ever-changing crisis and disruption to societies and economies around the globe.[1] As the COVID-19 pandemic continues to interrupt travel worldwide, the tourism industry, and the countries who rely on it as a major source of income, are in crisis. These processes have reconfigured economic capital flows and foreign investment in the global south. This is particularly the case in Tanzania, as tourism was Tanzania’s highest foreign exchange earner...

FAMILY AND CONSUMER SCIENCES EXTENSION AGENTS PERCEPTION OF A SUSTAINABLE EATING CURRICULUM FOR KENTUCKIANS

Lindley Barker
The population is rapidly increasing all over the world. As foods are produced for us to consume, the food system generates negative environmental impacts at each step. The extent of damage generated by food production depends on the amount of land, water, and energy depleted. These environmental impacts can result in reduced quantities of food produced, damages to the land and water used to grow/produce food, pollution of food, and food waste. All of which...

A Decoupled Engineering Methodology for Accurate Prediction of Ablative Surface Boundary Conditions in Thermal Protection Systems

Justin Cooper
The main objective of the present work is to demonstrate a method for prediction of aerothermal environments in the engineering design of hypersonic vehicles as an alternative to the current heritage method. Flat plate and stagnation point boundary layer theory require multiple assumptions to establish the current engineering paradigm. Chief among these assumptions is the similarity between mass and heat transfer. Origins of these assumptions are demonstrated and their relationship to conservative engineering design is...

REGULATORY MECHANISMS IN ARABIDOPSIS EMBRYOGENESIS

Sanjay Joshi
Plants have amazing regeneration properties with single somatic cells, or groups of cells able to give rise to fully formed plants. One means of regeneration is Somatic Embryogenesis (SE), by which an embryonic structure is formed that “converts” into a plantlet. Somatic embryogenesis has been used as a model for zygotic processes that are buried within layers of maternal tissues. Understanding mechanisms of somatic embryo induction and development are important as a more accessible model...

TRANSFORMATIVE LEARNING THROUGH ORAL NARRATIVE IN A PARTICIPATORY COMMUNICATION CONTEXT

Charles Madinger
This research investigates instructional narrative interventions for transformative learning among high orality reliant peoples. Two research questions asked: “Does an oral strategy of radio drama in a participatory environment lead to significant changes in knowledge and beliefs,” with a hypothesis stating there would be significant positive changes; and “When listeners experience narrative transport can it affect receptivity leading to knowledge and belief change,” and the hypothesis stated that narrative transport would correlate to higher positive...

THE (MILLENNIAL) TIMES, THEY ARE A’CHANGIN’

Hayley Hoffman
Drawing from over a decade of research, it can be said with relative certainty what millennial learners expected of their instructors when they were in the college classroom. But what about the expectations and needs of our current group of students, Generation Z? Because few studies exist on Gen Z in higher education spaces, this dissertation establishes a baseline of what these students might need and expect from market and generational research on this group...

GORGEOUS GORGEOUS GIRLS

Chioma Ezeano
Gorgeous Gorgeous Girls is a feminist collection. These are short stories that circumnavigate the peculiarities of Nigerian women. Each story takes a specific lens into the lives of the average Nigerian women, their daily survivals, their daily struggles—how these women examine life and existence. Through these variegated means, the stories ponder how societal ideologies, societal demands affect these women, especially the average Nigerian woman living beyond the poverty threshold. Each character wrestles, questions what it...

DEFORMATION OF WALL ROCKS AND OVERBURDEN SEQUENCES PROXIMAL TO SALT DIAPIRS IN SALT VALLEY, UTAH

William Swanger
Although deformation related to salt tectonics is generally considered to be an ancillary field of structural geology, owing to its relatively limited occurrence in the geologic record, the preponderance of salt-involved systems in multiple hydrocarbon-rich basins around the world (e.g., Gulf of Mexico, Atlantic passive margins, Iran, etc.) creates a necessity for understanding salt-related deformation. Traditionally, salt was considered to be relatively weak and thus was mostly unable to drive deformation of adjacent wall rocks...

PHOTOCATALYTIC APPLICATIONS OF TiO2 FOR CATECHOL DEGRADATION AND α-Fe2O3 FOR CARBON DIOXIDE REDUCTION AT AIR-SOLID INTERFACE

Md. Ariful Hoque
Natural and anthropogenic processes are emitting organic and inorganic pollutants, such as phenolic compounds, carbon dioxide (CO2), etc. in the atmosphere, which are increasing with time. In addition, to meet the energy demand of world’s growing population using nonrenewable fossil fuels are causing its depletion. Therefore, development of new technologies that can minimize atmospheric pollution and contribute to energy demand is imperative. Many methods or technologies have been developed for addressing those issues so far...

AMBIGUOUS APPALACHIANNESS

Crissandra George
The Appalachian Regional Commission (2022) designates 52 of Pennsylvania’s 67 counties as Appalachia, excluding only the southeast portion of the state. Matthew Ferrence, in Appalachia North, states that his "home is sometimes called Appalachia, sometimes Rust Belt, other times Midwest, even though very few who live there would accept any of those labels as correct" (xi). This ambiguous and fluid identity is due to the shaping, forming, and changing of Pennsylvania’s role within society from...

The Role of Sexual Difference in Plato's Timaeus

Mary Cunningham
My dissertation is a reading of Plato’s Timaeus that centers sexual difference and in particular femininity. I analyze the role of sexual difference in the framing of the dialogue as well as its accounts of body in the first and second discourse and its account of health in the third discourse. I argue that sexual difference, and, in particular, sexual reproduction, serves as a guiding paradigm of Timaeus’ entire project. I argue in each part...

Assessing Dialogic Communication Elements in Online Emergency Communication

Lauren Cain
Social media have been identified as powerful tools for two-way crisis communication, allowing officials to reach, inform, and motivate at-risk publics during emergencies. However, government use of social media during emergencies is a relatively new area of study and is thus understudied and undertheorized, with little evidence-based guidance for online messaging strategies during emergencies. Dialogic communication theory has recently been used as a framework to investigate the utility of social media as channels for facilitating...

Assessing the Temporal Relationship Between Changes in Neuroticism and Symptom Improvement in the Unified Protocol

Nicole Stumpp
Neuroticism is defined as the tendency to experience frequent and intense negative emotions accompanied by the belief that one could not cope adequately in response to stress. Neuroticism is associated with the development and maintenance of a range of emotional disorders (e.g., anxiety disorders, depression) and targeting this trait in treatment (rather than symptoms) may represent a more efficient approach to care. However, researchers have rarely measured neuroticism and symptoms frequently enough to establish temporal...
