Improving Radiotherapy Workflow: Evaluation And Implementation Of Deep Learning Auto-Segmentation In A Multi-User Environment, And Development Of Automatic Contour Quality Assurance System, Jingwei Duan

Theses and Dissertations--Radiation Medicine

Radiotherapy is a frequently used therapeutic modality for cancer patients. Accurately contouring of tumors and organs at risk (OARs) is critical for developing optimal treatment plans in radiotherapy, especially after the implementation of Intensity-modulated radiation therapy (IMRT) and Stereotactic Body Radiation Therapy (SBRT). The manual contouring process is time-consuming and suffers from inter-observer variations. However, manual contouring is often hindered by laborious clinical duties, leading to reduced effectiveness, and increased segmentation errors due to fatigue. Additionally, online adaptive radiation therapy(ART), which has been shown to benefit patient outcomes, places higher demands on contouring and quality assurance (QA) speed.

Understanding The Effects Of Age, Environmental Conditions, And Placement On Cockroach Gel Bait Performance, Isabelle Lucero

Theses and Dissertations--Entomology

Cockroach baits are one of the most effective tools used for German cockroach (Blattella germanica L.) control. This is due in part to the number of cockroach baits on the market with various matrix compositions and active ingredients, aiding in the control of resistant (physiologically and behaviorally) cockroach populations through bait rotation. However, it remains unclear how cockroach gel baits perform over time and under different environmental conditions. Therefore, we aged six cockroach gel baits for varying times (24 hours, one month, three months, six months) and at three relative humidities (15%, 40%, and 80%), and tested their performance …

Attitudes Of Therapists Surrounding Sand Tray Therapy With Adults, Madalyn Cooke

Theses and Dissertations--Family Sciences

Sand tray therapy provides a unique experience for adults and children to interact with their experiences and feelings from a distance. However, it is not used as frequently as talk therapy techniques in adult therapeutic treatment. The following thesis explores therapists’ attitudes about using sand trays with adults. A qualitative thematic analysis suggests that while some therapists deem sand trays as helpful with treatment, especially for clients who have a history of trauma, there are barriers for therapists to overcome in order to incorporate sand trays more frequently into practice with adult clientele.

Exploring The Distinction Between Support And Enabling In Families With Substance Use Disorder, Krystal N. King

Theses and Dissertations--Family Sciences

Substance use disorders (SUD) are a pervasive public health problem facing families in the United States. Although families are frequently urged to support loved ones who have SUD and cautioned against enabling them, there is a dearth of literature that distinguishes between supporting and enabling. Through qualitative interviews, this phenomenological study examined the experiences of eight parents with adult children with SUD who were currently in recovery. Five themes emerged from the data including: (a) living in despair, (b) addiction and recovery knowledge, (c) support group philosophy, (d) coping with addiction, and (e) differentiation. The results from this study suggest …

Conceptualizing Asexual Identities, Miranda L. Bejda

Theses and Dissertations--Family Sciences

In current literature, there is little congruence on an inclusive definition of human asexuality. This study explored individuals’ self-identification with asexuality as well as their conceptualization of that identity via thematic analysis. Using a Qualtrics XM survey, 374 individuals (18+ years old) answer questions regarding their experience as a person identifying themselves as asexual. Identity label authenticity, perceived impact of compulsory heterosexuality and heteronormativity on participants' current identity within the asexual spectrum, and prescribed heteronormative ideals were correlated. Thematic analysis revealed themes such as confusion about identity membership, feeling abnormal, the burden of living in a heteronormative society, and identity …

Your Problem Or Our Problem: How Clients' Evaluation Of The Problem Affects Therapeutic Progress In Therapy, Claire Elizabeth Nickell

Theses and Dissertations--Family Sciences

As systems theory has become the foundation of interpreting family interactions in therapy, it has become apparent that taking a systemic approach correlates with improved client growth and satisfaction outcomes. Clients’ systemic orientation to their problems may be influential in determining these outcomes in therapy. Thus, this study focused on how client’s systemic agreement can impact the outcomes of therapy and problem progress. We had 968 partnered individuals with differing economic backgrounds, education levels, and religious backgrounds participated in the study, as well as couples from age 18-72 with the mean age of 31.3. The couples’ SES ranged from below …

Molecular Genetic Studies Of Horses, Especially With Reference To Aggrecan And Dwarfism, John Edmund Eberth

Theses and Dissertations--Veterinary Science

This work consists of studies on dwarfism in Miniature horses and a study on breakdowns in Thoroughbreds in relation to gene aggrecan. A correction of the description and designation of D3 dwarf variant in aggrecan (ACAN) from the master’s thesis Chondrodysplasia-like dwarfism in the Miniature horse (2013). Commercial sequencing showed previous sequencing reads presented an artifact and not a single base deletion. Analysis showed a single base missense mutation in exon 8 identified as D3* was the actual cause. Multiple alleles of ACAN associated with chondrodysplastic dwarfism in Miniature horses by Eberth et al. (2018), corrected the …

The Long-Term Effects Of Wildfire Severity On Oak-Pine Communities And Their Microclimates, Scott Glenn Culbert

Theses and Dissertations--Forestry and Natural Resources

In the eastern U.S., fire-dependent tree species have historically dominated upland forest communities, but are now experiencing widespread regeneration challenges as a result of 20^th century fire suppression policies, and are being replaced by mesophytic species. Wildfires that contain areas of high burn severity may provide an important means of mitigating these challenges and facilitating fire-dependent species regeneration and recruitment into larger size classes. One mechanism by which high-severity fire can accomplish this is by modifying understory microclimate characteristics to be more conducive to these species’ growth. A wildfire within the Daniel Boone National Forest, Kentucky, USA, provided the …

This study presents an in-depth analysis of the potential production and economic impacts of maple syrup in Kentucky using a multi-method approach. First, the study applies a stochastic production model to assess the effects of climatic and tree variables on maple syrup yield. The results reveal that several variables, including the number of maple trees, taps, temperatures, tapping season length, and time, significantly affect maple syrup yield. Second, input-output …

Chemical Immobilization Of Helicopter-Captured Elk (Cervus Canadensis) And Survival Of Elk Calves In Southeastern Kentucky, Kathleen E. Williams

Theses and Dissertations--Forestry and Natural Resources

Safe and effective chemical immobilization is critical to minimize stress and risk of injury when capturing free-ranging, wild ungulates. Many traditionally favored high potency opioids have been phased out or become unavailable because of increased regulations, leading to the development of two pre-mixed combination drugs, butorphanol-azaperone-medetomidine (BAM) and nalbuphine-medetomidine-azaperone (NalMed-A). Both drugs have been used to chemically immobilize ungulates, but their efficacy has not been documented in elk captured and transported via helicopter. During 2020 – 2022, we chemically immobilized helicopter-captured female elk (Cervus canadensis) with a single IM-injection of BAM (n = 41) or NalMed-A (n = …

The overarching objective of this research was to enhance our comprehension of the three-dimensional precision of meteorological measurements obtained using small unmanned aircraft systems (UAS). Two complimentary experiments were conducted to achieve this objective.

The first experiment entailed the development and implementation of a system to determine the global navigation satellite system (GNSS) position accuracy on a UAS platform. This system was utilized to assess the static and dynamic accuracy of L1 and L1/L2 GNSS receivers in real-time kinematic (RTK) and non-RTK fix modes. Adjusted two-sample t-tests revealed significant differences in horizontal and vertical error between RTK and non-RTK receivers …

Ecological Risk Assessment Of Transgenic Conditional Lethality Systems For Genetic Biocontrol Strategies, Fernan Rodrigo Perez-Galvez

Theses and Dissertations--Entomology

Genetic strategies of insect pest control are receiving increased interest due to recent advances in genetic engineering. By introducing alleles that make males functionally sterile, genetically modified (GM) insects can be used in area-wide pest management programs similar to the Sterile Insect Technique (SIT). Genetic control strategies carry several potential benefits, including improved efficacy and specificity, lower operation costs, and reduced dependence on chemical insecticides, but their use is still controversial despite extensive technical documentation indicating their innocuity to humans and the environment. This hesitation is likely due to the novel nature of the approach.

While the first field applications …

Use Of A Nurse-Led Daily Goals Checklist To Improve Multidisciplinary Rounds In The Icu, Marissa Riley

DNP Projects

Research has shown a multidisciplinary rounding approach can improve patient care outcomes in the intensive care unit (ICU). Due to the complexity and wide range of the healthcare team, many patient details and treatment goals may be overlooked during daily patient rounds without a daily goals checklist to help ensure collaboration and communication of the multidisciplinary team. A nurse led daily goals checklist could be useful for framing nurse-provider conversations to promote comprehensive communication and collaboration. The purpose of this project was to improve adherence to a nurse-led daily goals checklist to improve communication and collaboration between the nurses and …

Finally, a framework for progressive rehabilitation that addresses deficits in motor control, strength, and endurance in scapula and shoulder musculature is presented …

Improving Tax Compliance In Indonesia Through The 2022 Voluntary Disclosure Program, Farid Al Firdaus

MPA/MPP/MPFM Capstone Projects

Developed or developing countries have conducted Voluntary Disclosure Programs (VDP) to increase tax revenues and taxpayers' compliance. Non-compliant taxpayers prefer this way to regular law enforcement to be more compliant. This study focuses on supporting Indonesia, the lowest tax-to-Gross Domestic Product (GDP) ratio in Asia and the Pacific, in improving its taxpayers' long-term compliance through the 2022 VDP; this amnesty had fewer participants, shorter periods, and higher rates than the first one in 2016. Using descriptive analysis, it is concluded that the 2022 VDP could reveal taxpayers' wealth known and unknown by the tax authority, increase revenue as a fraction …

Cares Act Unemployment Insurance Program Implementation In Kentucky: A Case Study, Alicia Landon

MPA/MPP/MPFM Capstone Projects

In March of 2020, the COVID-19 pandemic arrived in the United States. The deadly virus filled hospitals to capacity and caused approximately 375,000 deaths nationwide over the next nine months (Ahmad et al., 2021). In an effort to slow the spread of the Coronavirus, federal and state governments closed businesses and agencies within a matter of weeks. Almost as quickly as the threat to human health changed the lives of Americans, the secondary threat of economic disruption began to unfold. Nationwide unemployment rates increased from approximately 4% to 15% between February 2020 and April 2020 (U.S. Bureau of Labor Statistics, …

MPA/MPP/MPFM Capstone Projects

The United States has seen an increasing rate of substance use disorder among individuals. Those convicted and incarcerated are more likely to have substance use disorder. With correctional institutions becoming overcrowded, policymakers struggle to find an answer to the number of individuals incarcerated with substance use disorder. The Cabinet of Health and Family Services and the Department of Corrections created Supportive Assistance with Medication for Addiction Treatment (SAMAT) in Kentucky. SAMAT is an addictive services program focused on preventing overdose and relapse and aiding recidivism for individuals with opioid and alcohol use disorder. The SAMAT has been deemed successful through …

And The Survey Says ... A Qualitative Exploration Of Structurational Divergence From The Perspectives Of Nurse Managers Who Are Accountable For Patient Experience Measures, Lisa Carpenter Huddleston

Theses and Dissertations--Communication

For more than a decade, hospital leaders have focused on boosting patient experience scores as part of the federal government’s value-based purchasing (VBP) program. Hospitals that receive federal financial assistance (such as Medicare) are mandated to participate in the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS), a standardized survey that measures patients’ perceptions of their care. Results are publicly reported, and hospitals may be penalized on their reimbursements if they do not reach established benchmarks for patient experience. However, much debate has occurred about whether VBP has increased the quality of healthcare and whether the HCAHPS is an …

A Contextual History And Modern Edition Of J. Hyde’S 1799 English Trumpet Treatise: A New And Compleat Preceptor For The Trumpet & Bugle Horn: With The Whole Of Cavalry Duty As Approved Of And Ordered By His Royal Highness The Duke Of York … To Which Is Added A Selection Of Airs, Marches & Quick Steps For Three Trumpets, A Scale Of The Chromatic Trumpet With Airs Adapted For It, And A Collection Of Bugle Horn Duets, Clinton Gregory Linkmeyer

Theses and Dissertations--Music

For much of the trumpet’s long and varied history, it was considered a practical tool used for signaling more so than a music-making instrument. In 1614, Cesare Bendinelli wrote his Tutta L’arte Della Trombetta, which is often recognized as the first musical treatise written for trumpet. Scholars also recognize two other texts as being significant treatises: Girolamo Fantini’s Modo per imparare a sonare di tromba (1638), and Johann Ernst Altenburg’s Trumpeters’ and Kettledrummers’ Art (1795). The compilation and composition of A New and Complete Preceptor for the Trumpet and Bugle Horn by John Hyde in 1799 places it not only …

Exploring Cary Boyce's 'Kosmos', Kristina Ploeger-Hekmatpanah

Theses and Dissertations--Music

A text with many layers of depth married to music with a variety of methods of interpretation allows for an academically satisfying learning, rehearsal, and performance process. Choral directors, and the choristers they serve, enjoy scrutinizing all the ways they feel connected to or disconnected from the text and music in any piece that proves worth their efforts. American composer Dr. Cary Boyce’s (b. 1955) Kosmos (2007), a setting of a poem from Walt Whitman (1819-1892) of the same name, indeed provides the substance an academic group desires. At choral festivals in the Pacific Northwest during the 2021-2022 academic year, …

Multi-Omic Analysis Of Vegetative Propagation Induced Plant Rejuvenation In Grapevines: Implications For The Generation Of Locally Adapted Cultivars Using Epigenetics, Tajbir Raihan

Theses and Dissertations--Plant and Soil Sciences

Epigenetic memory of the growing environment is a process capable of increasing plants’ resilience to abiotic stimuli. The cultivated grapevine is a long-living perennial species with a large corpus of research suggesting that plant adaptation to the environment has implications for the selection of genetic material in a changing climate. Moreover, vine age has been traditionally correlated with enhanced fruit quality. Recent studies have shown that environment/age-acquired traits in grapevine (e.g., adaptation to the growing environment and fruit/wine quality, respectively) are associated with epigenetic mechanisms. These studies also indicate that of propagation type affects the maintenance/erasure of the acquired traits …

Trait Impulsivity And Acute Alcohol Responses As Markers Of Binge Drinking In Young Adults, Holley Jamison

Theses and Dissertations--Psychology

Impulsivity, tolerance to alcohol-induced motor impairment, and high sensitivity to alcohol-induced disinhibition each have empirical support as markers of alcohol-related problems. However, research on alcohol response and personality-based markers of risk have remained largely independent lines of research. This dissertation examined how individual differences in these well-established markers may interact to additively contribute to heavy drinking.

Participants were 96 young adults (21-33 years old). with no history of AUD. They self-reported their drinking habits over the prior 90 days, and behavioral tasks measuring disinhibition and motor impairment were administered on two separate days following two alcohol doses (active [0.65 g/kg] …

Measuring Ground Surface Elevation Changes In A Slow-Moving Colluvial Landslide Using Combinations Of Regional Airborne Lidar, Uav Lidar And Uav Photogrammetric Surveys, Sarah E. Johnson, William C. Haneburg, Lindsey Sebastian Bryson, Matthew M. Crawford

Faculty, Staff, and Affiliated Publications--KGS

Slow-moving, chronically destructive landslides are projected to grow in number globally in response to precipitation increases from climate change, and land disturbances from wildfire, mining and construction. In the Cincinnati and northern Kentucky metropolitan area, USA, landslides develop in colluvium that covers the steep slopes along the Ohio River and its tributaries. Here we quantify elevation changes in a slow-moving colluvial landslide over 14 years using county-wide lidar, uncrewed aerial vehicle (UAV) structure-from-motion (SfM) surveys and a UAV lidar survey. Because the technology and quality differ between surveys, the challenge was to calculate a threshold of detectable change for each …

Mapping Landslide Susceptibility Over Large Regions With Limited Data, J. B. Woodard, Benjamin B. Mirus, Matthew M. Crawford, D. Or, B. A. Leshchinsky, K. E. Allstadt, N. J. Wood

Faculty, Staff, and Affiliated Publications--KGS

Landslide susceptibility maps indicate the spatial distribution of landslide likelihood. Modeling susceptibility over large or diverse terrains remains a challenge due to the sparsity of landslide data (mapped extent of known landslides) and the variability in triggering conditions. Several different data sampling strategies of landslide locations used to train a susceptibility model are used to mitigate this challenge. However, to our knowledge, no study has systematically evaluated how different sampling strategies alter a model's predictor effects (i.e., how a predictor value influences the susceptibility output) critical to explaining differences in model outputs. Here, we introduce a statistical framework that examines …

Life Cycle Assessment Of Air Classification As A Sulfur Mitigation Technology In Pine Residue Feedstocks, Ashlee Edmonson

Theses and Dissertations--Biosystems and Agricultural Engineering

Sulfur accumulation during biofuel production is pollutive, toxic to conversion catalysts, and causes the premature breakdown of processing equipment. Air classification is an effective preprocessing technology for ash and sulfur removal from biomass feedstocks. A life cycle assessment (LCA) sought to understand the environmental impacts of implementing air classification as a sulfur-mitigation technique for pine residues. Energy demand and material balance for preprocessing were simulated using SimaPro and the Argonne National Laboratory’s GREET model, specifically focusing on comparing the global warming potential (GWP) of grid electricity versus bioelectricity scenarios. Overall, the grid electricity scenario had a GWP impact over 7 …

Multi-Domain Adaptation For Image Classification, Depth Estimation, And Semantic Segmentation, Yu Zhang

Theses and Dissertations--Computer Science

The appearance of scenes may change for many reasons, including the viewpoint, the time of day, the weather, and the seasons. Traditionally, deep neural networks are trained and evaluated using images from the same scene and domain to avoid the domain gap. Recent advances in domain adaptation have led to a new type of method that bridges such domain gaps and learns from multiple domains.

This dissertation proposes methods for multi-domain adaptation for various computer vision tasks, including image classification, depth estimation, and semantic segmentation. The first work focuses on semi-supervised domain adaptation. I address this semi-supervised setting and propose …

The Basil Technique: Bias Adaptive Statistical Inference Learning Agents For Learning From Human Feedback, Jonathan Indigo Watson

Theses and Dissertations--Computer Science

We introduce a novel approach for learning behaviors using human-provided feedback that is subject to systematic bias. Our method, known as BASIL, models the feedback signal as a combination of a heuristic evaluation of an action's utility and a probabilistically-drawn bias value, characterized by unknown parameters. We present both the general framework for our technique and specific algorithms for biases drawn from a normal distribution. We evaluate our approach across various environments and tasks, comparing it to interactive and non-interactive machine learning methods, including deep learning techniques, using human trainers and a synthetic oracle with feedback distorted to varying degrees. …
