A MULTI-METHOD INVESTIGATION OF THE MODERN SEDIMENTATION AND LATE HOLOCENE PALEOLIMNOLOGY OF JUNE LAKE (MONO COUNTY, CA), AND A SURVEY-BASED ANALYSIS OF NINTH GRADERS’ ATTITUDES TOWARDS GEOLOGY

Eva Lyon
Three distinct manuscripts comprise this dissertation. The first analyzes the modern sedimentary basin of June Lake, a small glacial lake in the eastern Sierra Nevada of California (USA) using a number of data sets, including bathymetry, surface sediment composition, and seismic stratigraphy. The seismic survey revealed sublacustrine morphological features that suggest the basin originated due to ice scour, as well as four acoustically distinct stratigraphic units that reflect the history of sedimentation following glacial scouring....

TOBACCO USE AND NICOTINE WITHDRAWAL AMONG PATIENTS WITH MENTAL ILLNESS

Yazan Al-Mrayat
People with mental illness (MI) are disproportionately affected by tobacco use compared to the general population. In fact, it is estimated that people with MI consume approximately 44% of cigarettes smoked in the United States. Moreover, the MI population is at greater risk for the negative social, economic, and health consequences associated with tobacco use and are reported to have 25-year shorter life expectancies than the general population. The impact of tobacco use is further...

Reserved for the Whole Earth

Eric Robsky Huntley
This dissertation examines geographic forms of evidence in the practices of landscape architects and geographers. I analyze evidence not only as an epistemic phenomenon, but as an aesthetic one, as well. Convincing an audience that the world is (or should be) one way and not another requires that knowledges be stacked, extended, and stitched together in a manner admissable to an audience. In the first two chapters, I use the case of the landscape architect...

Street Affects

Laçin Tutalar
This paper argues that affective moments between street musicians and the audience in Istanbul, Turkey suggest a loose connection to open and highly affective practices of hearing. The street brings them together during the moments of performance. The performance twists the power of sound that the musician makes and draws that into visualization of the moment, which underlines a peculiar affective attachment on the audience's side. The city's, musician's, and the listening practices' significance in...

Conversation Goals, Communication Satisfaction, and Relational Dynamics While Navigating Alzheimer’s Disease

Elizabeth Spencer
Currently there are more than 16 million unpaid Alzheimer’s disease and dementia caregivers in the United States. These caregivers are often family members of the person living with dementia, and as they navigate the process of giving care to the patient, they must also maintain relationships with each other. Families enter the dementia experience with a history of their relational experiences, and their relational experiences potentially change as they navigate family experiences after the dementia...

A FRAMEWORK FOR HETEROLOGOUS BIOSYNTHESIS OF NATURAL PRODUCTS IN MAMMALIAN CELLS VIA POLYMER-MEDIATED TRANSFECTIONS

Logan Warriner
With the promise to treat a multi-faceted list of serious inherited and acquired diseases, such as cancer, neurodegenerative and infectious diseases, and inherited genetic indications, gene therapy has continued to push the boundaries of traditional medicine since its earliest implementation. While much progress has been made, clinical success has largely remained elusive. Immunogenicity, difficulty producing commercially relevant quantities, and having a limited genetic payload still limits the ability of viruses to act as directed delivery...

IONIC BONDING CURRICULUM UNIT

Mary Lamar
This mixed methods study compared two groups of high school students’ understanding of the ionic bond and the dissolving process. A 5 lesson curriculum unit was developed using Taber’s electrostatic framework (1997) focusing on the electrostatic forces between ions compared to a molecular framework (business-as-usual) and the Next Generation Science Standards (NGSS Lead States, 2013). The lessons were developed to integrate spatially integrated experiences. Experimental (new curriculum unit) and business-as-usual (criss-cross method) students had their...

POPULATION PHARMACOKINETIC MODELING AND GENETIC ASSOCIATION ANALYSIS IN INFANTS WITH NEONATAL ABSTINENCE SYNDROME RECEIVING MORPHINE OR CLONIDINE

Fei Tang
Neonatal abstinence syndrome, or NAS, is a postnatal opioid withdrawal syndrome occurring in 55% to 94% of neonates as a result of in utero exposure to opioids. It has emerged as a significant public health issue, as its incidence more than quadrupled in the past decade. There is significant variability in disease severity and treatment outcomes in neonates with NAS due to patient-specific factors and treatment- or site-specific factors. To understand what contributes to variability...

Kasey Waddell
During the Spring 2020 semester, students within the applied behavior analysis/special education/interdisciplinary early childhood education program were conducting applied thesis projects within typical contexts as part of their fulfillment of the requirements of a master’s degree program. Due to the coronavirus disease 2019 (COVID-19), public schools and related facilities closed with no plans to reopen within the time frame to allow for graduation for students in the last semester of their graduate program. Students were...

Fiscal Year 2011 FHWA-536 Report for the Kentucky Transportation Cabinet

, , &
The Federal Highway Administration (FHWA) requires state transportation agencies to submit a biennial report on local highway finances. The purpose of these reports is to provide FHWA with the data it needs to capture the financing of highway activities at the local level. Based on this information, it can identify trends in revenue, expenditures, investments, and program development, and in turn make decisions about future investments. The report, FHWA-536, asks agencies to report on four...

The Effects of Opioids on Kentucky's Workforce

Michael W. Clark, Jenny A. Minier, Charles Courtemanche, Bethany L. Paris & Michael T. Childress
Opioid abuse represents a significant and growing public health issue for both the nation and Kentucky. In 2016, opioids contributed to more than 62,000 deaths nationally and 1,406 deaths in Kentucky. National studies have placed the societal costs of opioid abuse at $55.7 billion in 2007 and $78.5 billion in 2013 (Birbaum et al. (2011) and Florence et al. (2016)). These costs included increased health care expenditures, higher criminal justice costs, and lost earnings due...

METHODOLOGICAL CONSIDERATIONS FOR THE DETERMINATION OF THE CRITICAL RESISTANCE FOR THE DEADLIFT

Alexander Moss
This study determined if plate movement during conventional deadlifting affects critical resistance (CR) estimates derived from the linear work limit (Wlim) versus repetitions relationship. Eleven subjects completed 1-repetition maximum (1RM) deadlift testing followed by 8 visits, to determine the number of repetitions to failure at 50%, 60%, 70%, and 80% 1RM for both reset (RS) and touch-and-go (TG) methods, respectively. The CR was calculated as slope of the line of total work completed (repetitions ×...

COARSE-GRAINED DYNAMICALLY ACCURATE SIMULATIONS OF IONIC LIQUIDS AT VACUUM-INTERFACE

Tyler Stoffel
Ionic liquids, possessing improved properties in many areas of technical application, are excellent candidates as components in development of next-generation technology, including ultra-high energy batteries. If they are thus applied, however, extensive interfacial analysis of any selected ionic configuration will likely be required. Molecular dynamics (MD) provides an advantageous route by which this may be accomplished, but can fall short in observing some phenomena only present at larger time/length scales than it can simulate. Often...

Full-Depth Reclamation of Asphaltic Concrete Pavements

Tony L. Beckham, Brad W. Rister & Charlie Sun
The Kentucky Transportation Cabinet (KYTC) has used a full-depth reclamation (FDR) process over the past few years to rehabilitate asphalt pavements exhibiting widespread base failures. FDR transforms existing hot-mix asphalt (HMA) pavement and underlying granular materials into a stabilized base layer. The stabilized layer is then overlaid with a new pavement surface layer. Until now, deciding when and how to use the FDR process has not been well specified in Kentucky — the Cabinet has...

THE SOUND OF LEADERSHIP

John Hill
Within this dissertation I focused on the examination of local activist musicians’ self-leadership strategies and the method in which they lead social change movements. Additionally, I sought to increase the understanding of charismatic leadership, self-leadership strategies of local activist musicians, and the method in which local activist musicians lead social movements. To my knowledge, no published studies have explored local activist musicians’ self-leadership strategies. Therefore, this study is significant because I (a) explored a term...

Applications of Drones in Atmospheric Chemistry

Travis Schuyler
The emission of greenhouse gases (GHGs) has changed the composition of the atmosphere during the Anthropocene. A major technical and scientific challenge is quantifying the resulting fugitive trace gas fluxes under variable meteorological conditions. Accurately documenting the sources and magnitude of GHGs emission is an important undertaking for discriminating contributions of different processes to radiative forcing. Therefore, the adverse environmental and health effects of undetected gas leaks motivates new methods of detecting, characterizing, and quantifying...

Multiscale Modeling of Structure-Function Relationships of Organic Semiconductors

Shi Li
While optoelectronic devices built from organic semiconductors (OSC) continue to find their way into the commercial landscape, there remain numerous challenges to overcome to supplant traditional semiconductors in many technologies. Chief among these are low performance metrics relative to devices with conventional semiconductors and device stability. In order to overcome these challenges, a wide range of new OSC and processing technologies have been developed. However, there remains limited fundamental understanding of the relationship between molecular...

TRANSFORMATIVE SUBJECTS

Emily R. DeHaven
Through this dissertation, I explore the ways that authors and editors use the form of children’s periodicals to discuss questions of childhood independence, the structure of the family, and the balance of power between children and adults with regards to literary texts. I examine the ways in which adults and children negotiate control over the periodicals and over the images of transformation present within those texts. Periodicals offer a unique opportunity for interaction between readers...

ELECTROPHORESIS IN HETEROGENEOUS HYDROGELS AND APPLICATIONS IN SURFACE PATTERNING

Ning Ge
The creation of chemical micropatterns on surfaces makes it possible to add unique chemical functionality to surfaces, modifying properties such as wettability, or even adding the ability to selectively bind other molecules. The creation of biochemical surface patterning in particular is useful in a variety of fields including tissue engineering and highthroughput drug screening. There are many existing surface patterning techniques which focus on precise control over the patterned geometry, even down to submicron scale...

Can Less Be More?

Xian Wu
The present study addressed a core research question of “Can less be more?” concerning study load, which has become increasingly worrisome and controversial around the world. This idea reflects the philosophy of pursuing efficiency and effectiveness on learning, namely that a lighter study load may result in more successful academic achievement. The study adopted the IPO (input-process-output) model to address five interrelated research questions: 1) What are the structural characteristics of study load? 2) Is...

SOIL BULK DENSITY EFFECTS ON RUNOFF ESTIMATION

Colton Pugh
Urbanization has long been a major factor in the hydrology of surrounding areas. Engineers are commonly tasked with mitigating the extra runoff that urbanization brings with it. The NRCS Curve Number (CN) method is a commonly-used approach to predicting the amount of runoff that will be experienced from a given area. However, this method is known to be highly simplified in model of the processes involved. This study focused on determining the relationships between soil...

SAFETY CONCEPTS FOR EVERY RIDE

Shannon Wood
Rotational falls are the leading cause of death and serious injury in the equestrian sport of eventing. Previous studies to develop safety devices used physical models representing one or at most several physical situations leading to different designs and no common understanding. In this thesis, a statistical ensemble model is developed and applied to generate and evaluate 10,000 different situations that might potentially lead to rotational falls. For accurate statistical representation of the horse and...

Ab initio Investigation on the Surface Chemistry of Functionalized Titania Membranes

Evan Hyde
Titania (titanium dioxide) is a metal oxide which has recently been investigated as a photocatalyst, most commonly for use in hydrolysis, which absorbs mostly in the UV range. However, the range of absorption can be shifted to fall within the visible light range either by doping or by functionalizing the surface with atomic or molecular adsorbates. Over the course of this research, a series of Density Functional Theory (DFT) calculations are performed to ascertain the...

HIGH FREQUENCY OSCILLATIONS IN THE EPILEPTIC BRAIN

AMIR AL-BAKRI
About a third of all epilepsy patients may experience seizures that are resistant to medication. Surgical resection may be an option for some of these patients, but localization of the epileptogenic zone is difficult and expensive. For this process, the seizures must be observed and recorded in a clinical setting over several days. High-frequency oscillations (HFOs) have emerged as a possible biomarker for predicting the epileptogenic zone from a brief interictal recording of brain electrical...

VILLAGE-TEMPLE CONSCIOUSNESS IN TWO JAFFNA TAMIL VILLAGES IN POST-WAR SRI LANKA

Pathmanesan Sanmugeswaran
This dissertation investigates how community rebuilding is occurring in a gravely damaged, post-conflict society. Specifically, it looks at how people in two villages in Tamil, Hindu, Jaffna, Sri Lanka, are using their ‘sense of place’ and ‘place-making practices’ or what I call here their ‘village-temple consciousness’ or village consciousness, to maintain and rebuild their communities after war to make them, once again, places in which they feel a comfortable sense of belonging. This is a...
