Assessing The Criteria For Definition Of Perimembranous Ventricular Septal Defects In Light Of The Search For Consensus, Justin T. Tretter, Vi-Hue Tran, Seth Gray, Hieu Ta, Rohit S. Loomba, William O'Connor, Diane E. Spicer, Andrew C. Cook, Robert H. Anderson

Pathology and Laboratory Medicine Faculty Publications

Background: Discussions continue as to whether ventricular septal defects are best categorized according to their right ventricular geography or their borders. This is especially true when considering the perimembranous defect. Our aim, therefore, was to establish the phenotypic feature of the perimembranous defect, and to establish the ease of distinguishing its geographical variants.

Methods and results: We assessed unrepaired isolated perimembranous ventricular defects from six historic archives, subcategorizing them using the ICD-11 coding system. We identified 365 defects, of which 94 (26%) were deemed to open centrally, 168 (46%) to open to the outlet, and 84 (23%) to the inlet …

Effects Of Increased Precipitation On The Life History Of Spring- And Autumn-Germinated Plants Of The Cold Desert Annual Erodium Oxyrhynchum (Geraniaceae), Yanfeng Chen, Xiang Shi, Lingwei Zhang, Jerry M. Baskin, Carol C. Baskin, Huiliang Liu, Daoyuan Zhang

Biology Faculty Publications

Future increased precipitation in cold desert ecosystems may impact annual/ephemeral plant species that germinate in both spring and autumn. Our primary aim was to compare the life history characteristics of plants from spring-germinating (SG) and autumn-germinating (AG) seeds of Erodium oxyrhynchum. Plants in field plots with simulated increases in precipitation of 0, 30 and 50 % in spring and summer were monitored to determine seedling survival, phenology, plant size, seed production and biomass accumulation and allocation. Germination characteristics were determined in the laboratory for seeds produced by plants in all increased precipitation treatments. Increased precipitation in spring significantly improved survival …

Quantifying The Impact Of Weather Events On Travel Time And Reliability, Xu Zhang, Mei Chen

Kentucky Transportation Center Faculty and Researcher Publications

It is of practical significance to understand the specific impact of weather events on the operating condition of the surface transportation system so that proactive and reactive strategies can be quickly implemented by transportation agencies to minimize the negativity resulted from adverse weather events. Many studies have been conducted on quantifying such effects yet suffer from limitations such as subjectively defining a time window under uncongested conditions and not being able to account for the severe impact from weather events which result in travel time unreliability. To overcome those shortcomings in existing literature, an integrated data mining framework based on …

The Three-Year Impact Of The Affordable Care Act On Disparities In Insurance Coverage, Charles J. Courtemanche, James Marton, Benjamin Ukert, Aaron Yelowitz, Daniela Zapata, Ishtiaque Fazlul

Economics Faculty Publications

Objective
To estimate the impact of the major components of the ACA (Medicaid expansion, subsidized Marketplace plans, and insurance market reforms) on disparities in insurance coverage after three years.

Data Source
The 2011-2016 waves of the American Community Survey (ACS), with the sample restricted to nonelderly adults.

Design
We estimate a difference-in-difference-in-differences model to separately identify the effects of the nationwide and Medicaid expansion portions of the ACA using the methodology developed in the recent ACA literature. The differences come from time, state Medicaid expansion status, and local area pre-ACA uninsured rates. In order to focus on access disparities, we …

The Digital Knowledge Economy Index: Mapping Content Production, Sanna Ojanperä, Mark Graham, Matthew Zook

Geography Faculty Publications

We propose the construction of a Digital Knowledge Economy Index, quantified by way of measuring content creation and participation through digital platforms, namely the code sharing platform GitHub, the crowdsourced encyclopaedia Wikipedia, and Internet domain registrations and estimating a fifth sub-index for the World Bank Knowledge Economy Index for year 2012. This approach complements conventional data sources such as national statistics and expert surveys and helps reflect the underlying digital content creation, capacities, and skills of the population. An index that combines traditional and novel data sources can provide a more revealing view of the status of the world’s digital …

Material Atmospheres: Theorising Recent Shifts In Interior Visualisation, Gregory Marinic

Interiors Faculty Publications

Much like Walter Benjamin's analysis of the Parisian arcades during the interwar years of the early 20th century, emerging methods of seeing interior spaces reveal a deeper gaze into the contextual, material, and phenomenological conditions that produce more nuanced visions of interiority. A collective consciousness surrounding these constructed narratives is reflected in charged associations with the most salient imperatives of our time—globalisation, resource depletion, ecological degradation, and political instability—as well as their corresponding effects on the built environment. These visual provocations have incrementally percolated up to embody an expanding field of design activism for educators, theorists, practitioners, and students. How …

Use Of A Cross-Sectional Survey In The Adult Population To Characterize Persons At High-Risk For Chronic Obstructive Pulmonary Disease, Roy A. Pleasants, Khosrow Heidari, Jill Ohar, James F. Donohue, Njira Lugogo, Chelsea L. Richard, Sarojina Kanotra, David M. Mannino, Monica Kraft, Winston Liao, Charlie Strange

Internal Medicine Faculty Publications

Rationale/Objective: The Behavioral Risk Factor Surveillance System (BRFSS) health survey has been used to describe the epidemiology of chronic obstructive pulmonary disease (COPD) in the US. Through addressing respiratory symptoms and tobacco use, it could also be used to characterize COPD risk. Methods: Four US states added questions to the 2015 BRFSS regarding productive cough, shortness of breath, dyspnea on exertion, and tobacco duration. We determined COPD risk categories: provider-diagnosed COPD as self-report, high-risk for COPD as ≥ 10 years tobacco smoking and at least one significant respiratory symptom, and low risk was neither diagnosed COPD nor high risk. Disease …

Good To The Last Drop: The Emergence Of Coffee Ringspot Virus, Michael Goodin, Antonia Dos Reis Figueira

Plant Pathology Faculty Publications

Two and a half billion times per day a human hand reaches for a fresh cup of coffee. Although arguably dispensable for life per se, with an industry value of US$174 billion, coffee provides the lifeblood that sustains economies of producing countries located in the “coffee belt” situated between the Tropics of Cancer and Capricorn. As a “solvent” in which many human interactions take place, coffee is witness to the broad spectrum of human activities from the mundane to the pleasurable and personal. However, in opposition to its economic, cultural, and physiological importance, diseases such as coffee rust (caused by …

Southern History On Screen, Bryan M. Jack

Civil Rights

Hollywood films have been influential in the portrayal and representation of race relations in the South and how African Americans are cinematically depicted in history, from The Birth of a Nation (1915) and Gone with the Wind (1939) to The Help (2011) and 12 Years a Slave (2013). With an ability to reach mass audiences, films represent the power to influence and shape the public's understanding of our country's past, creating lasting images—both real and imagined—in American culture.

In Southern History on Screen: Race and Rights, 1976–2016, editor Bryan Jack brings together essays from an international roster of scholars …

Investment In Human Capital And Labor Mobility: Evidence From A Shock To Property Rights, Christopher P. Clifford, William C. Gerken

Institute for the Study of Free Enterprise Working Papers

We show that the assignment of property rights to client relationships affects employee behavior in the industry for financial advice. Our identification comes from staggered firm-level entry into the Protocol for Broker Recruiting. The protocol effectively transfers the ownership of the client relationship from the firm to the employee. We document that entering into the protocol increases employee labor mobility among member firms. Further, we find that upon protocol inclusion, employees are less likely to generate customer complaints and more likely to invest in their own general human capital, but less likely to invest in firm-specific human capital. We use …

Social Networks, Identity, Health, And Quality Of Life Among Older Gay And Lesbian Individuals In Rural Environments, Marc Aaron Guest

Theses and Dissertations--Gerontology

The goal of this dissertation was to explore aging lesbian and gay individuals living in rural communities, in terms of their social networks and the relationships between these networks, identity, health, and quality of life. Guiding the study were three overarching questions. Using a multi-method design, the research was grounded within a socio-ecological context and focused on how structural systems create pathways for health and are affected by social position (intersectionality). Participants (n=25) were recruited from Kentucky (n=20), West Virginia (n=3), and Tennessee (n=2). Thirteen participants self-identified as gay and twelve as lesbian. Findings highlight the complexity of the aging …

Image-Based Roadway Assessment Using Convolutional Neural Networks, Weilian Song

Theses and Dissertations--Computer Science

Road crashes are one of the main causes of death in the United States. To reduce the number of accidents, roadway assessment programs take a proactive approach, collecting data and identifying high-risk roads before crashes occur. However, the cost of data acquisition and manual annotation has restricted the effect of these programs. In this thesis, we propose methods to automate the task of roadway safety assessment using deep learning. Specifically, we trained convolutional neural networks on publicly available roadway images to predict safety-related metrics: the star rating score and free-flow speed. Inference speeds for our methods are mere milliseconds, enabling …

Optimal Gateway Placement In Low-Cost Smart Cities, Oluwashina Madamori

Theses and Dissertations--Computer Science

Rapid urbanization burdens city infrastructure and creates the need for local governments to maximize the usage of resources to serve its citizens. Smart city projects aim to alleviate the urbanization problem by deploying a vast amount of Internet-of-things (IoT) devices to monitor and manage environmental conditions and infrastructure. However, smart city projects can be extremely expensive to deploy and manage partly due to the cost of providing Internet connectivity via 5G or WiFi to IoT devices. This thesis proposes the use of delay tolerant networks (DTNs) as a backbone for smart city communication; enabling developing communities to become smart cities …

Economic Impact Of Ethanol Biorefineries In The U.S. Midwest From 2001 To 2015: A Quasi-Experimental Approach, Scott W. Hall

Theses and Dissertations--Agricultural Economics

The objective of this dissertation is to analyze the economic impact of newly operational ethanol biorefineries on rural counties in the U.S. Midwest region for the period 2001 to 2015 using a quasi-experimental approach. Rapid growth in the ethanol industry expanded the number of ethanol plants located in the U.S. Midwest from 54 in 2001 to 173 in 2015. Out of the counties with 119 new ethanol biorefineries, 97 counties met the general treatment criteria defined in this dissertation, but only 56 of those counties qualified for the rural treatment criteria. Counties with ethanol biorefineries that qualified for treatment were …

Superintendents And The Micropolitics Of Innovation In Rural School Districts, Catherine Nunn Lawless

Theses and Dissertations--Education Sciences

Research shows that public school districts that follow traditional means of instruction and assessment are insufficiently preparing students for success in the today’s global world. As a result, students are entering into higher education institutions and the workforce without the necessary skills to succeed in these 21^st century environments. Extant literature suggest that there is a broad consensus on this perspective in public and private sectors nationally and globally. Evidence shows that some school district superintendents and their respective school boards continue to focus on improving the current practices and student academic performance and assessment. Other instructional leaders recognize …

2018 Kentucky Dental Workforce Update, Sydney P. Thompson, Melissa Slone, Frances J. Feltner

Center of Excellence in Rural Health Workforce Reports

The perception that oral health is in some way less important than and separate from general health has been deeply ingrained in the American consciousness. Many Americans are unaware of ways to preserve oral health and may not recognize signs indicating they are in trouble. Poor oral health can contribute to various diseases including endocarditis, cardiovascular disease, diabetes, HIV/AIDS, osteoporosis, and Alzheimer’s disease.

Kentuckians often fair worse on a multitude of health measures, especially rural Kentuckians. According to the 2019 County Health Rankings data, when compared to US averages, Kentuckians are more likely to smoke (18% vs 23%), be obese …

Open Secrets, Congressional Oversight, And The Geopolitics Of The Cia Drone Program, Marita C. Murphy

Theses and Dissertations--Geography

Analyzing four congressional hearings that publicly discuss the CIA’s ‘secret’ drone program, this thesis considers the interaction between publicity and secrecy in facilitating practices of later-modern warfare. Specifically, I examine the content of these drone hearings within the broader context of leaks, Obama administration speeches, and public interest in CIA drones to better understand how open secrecy engages with public oversight. I argue these hearings are deceptively productive. While they largely fail as oversight events, the hearings facilitate numerous unexpected outcomes—including the normalization and entrenchment of the CIA drone program. Paradoxically then, publicity proves essential to the maintenance and acceptance …

Visualizing Barrier Dune Topographic State Space And Inference Of Resilience Properties, Li-Chih Hsu

Theses and Dissertations--Geography

The linkage between barrier island morphologies and dune topographies, vegetation, and biogeomorphic feedbacks, has been examined. The two-fold stability domain (i.e., overwash-resisting and overwash-reinforcing stability domains) model from case studies in a couple of islands along the Georgia Bight and Virginia coast has been proposed to examine the resilience properties in the barrier dune systems. Thus, there is a need to examine geographic variations in the dune topography among and within islands. Meanwhile, previous studies just analyzed and compared dune topographies based on transect-based point elevations or dune crest elevations; therefore, it is necessary to further examine dune topography in …

Las Islas En La Literatura Castellana De La Baja Edad Media, Martha Elena Granados Sáenz

Theses and Dissertations--Hispanic Studies

This dissertation explores references to islands in 13^th and 14^th century Iberian literature in a corpus of encyclopedias, travel books and chivalry novels from 1223 through 1396. I explore how island geography became part of the Medieval imago mundi. Many Medieval readers were interested in these faraway lands where, they believed, monstrous races flourished, sea monsters lurked, and Paradise awaited to be rediscovered. The physical and human geography featured in these narratives, gave birth to an imaginary, utopian, exotic, extravagant, and mysterious concept of “islandness” located in idyllic places to be interpreted as cognitive maps of the …

School-Based Hpv9 Vaccination Clinic In The Cumberland Valley Area Development District Of Kentucky, Eryne Wirthorn

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Human Papillomavirus (HPV) is a group of more than 150 virus that can cause genital warts and cancers of the oropharynx, cervix, vagina, vulva, penis, and anus. A preventive vaccine currently exists that protects against seven oncogenic HPV strands and two strands that cause genital warts. Current guidelines for HPV9 vaccination consist of a 2-dose series delivered at 0 and 6 months for males and females ages 9-14, and a 3-dose series delivered at 0, 2, and 6 months for those ages 15-26.

While up-to-date (UTD) vaccination rates have increased across the Unites States, in 2017, only about 52.4% of …

Evidence-Based Music Therapy Treatment To Elevate Mood During Acute Stroke Care, Jessica L. Rushing

Theses and Dissertations--Rehabilitation Sciences

Stroke is the fifth leading cause of death in the U.S. with approximately 795,000 Americans experiencing a stroke each year. In addition to common difficulties with communication and physical impairments following stroke, psychosocial impacts warrant assessment and treatment. Experiencing a stroke can lead to depression, mood disorders, and difficulties with emotion regulation. It is well documented that post-stroke depression (PSD) affects a third of stroke survivors. Higher levels of depression and depressive symptoms are associated with a less efficient use of rehabilitation services, poor functional outcomes, greater odds of hospital readmission, negative impacts on social participation, and increased mortality. The …

Utilizing Large Scale Datasets To Evaluate Aspects Of A Sustainable Bioeconomy, Gwanseon Kim

Theses and Dissertations--Agricultural Economics

This dissertation combines large scale datasets to evaluate crop prediction, land values, and consumption of a crop being considered to advance a sustainable bioeconomy. In chapter 2, we propose a novel application of the multinomial logit (MNL) model to estimate the conditional transition probabilities of crop choice for the state of Kentucky. Utilizing the recovered transition probabilities the forecast distributions of total acreages for alfalfa, corn, soybeans, tobacco, and wheat produced in the state from 2010 to 2015 can be recovered. The Cropland Data Layer is merged with the Common Land Unit dataset to allow for the identification of crop …
