Federal Improper Payment Mandates And Their Financial Risk For State Governments, Seth Grove

MPA/MPP/MPFM Capstone Projects

As the recipient of billions in federal dollars, state governments are key stakeholders in combatting improper payments. While federal improper payment laws have mandated responsibility to federal agencies, states ultimately administer numerous federal programs, thus are subject to the same improper payment laws. Due to statistical sampling and extrapolation requirements in federal audits, state governments are at a tremendous financial risk for federal disallowances in administering federal programs. Federal reports and academic literature can inform state governments on improving state policies to mitigate their financial risk of federal improper payment laws.

The Effect Of Disability On Unemployment Claim Duration In Kentucky And The Surrounding States, James Tatum

MPA/MPP/MPFM Capstone Projects

The duration of unemployment insurance claims in Kentucky are over 30% longer on average than unemployment claims in the surrounding states. This study uses a time-series regression to compare data from Kentucky and the surrounding states to find correlations between unemployment insurance claim duration and the percentage of a state’s population that reports having at least one disability. No significant correlation was found between a state’s population with a disability and unemployment claim duration but there was a significant negative correlation between unemployment claim duration and the total amount of Social Security Disability Insurance and Supplemental Security Income payments people …

Impact Of Government Regulations And Programmatic Decisions On Demand For A Novel Contraceptive Product In Developing Countries, Matthew Westling

MPA/MPP/MPFM Capstone Projects

Family planning and contraceptive use is becoming an area of emphasis for developing countries. The important role family planning has in the growth and development of personal wealth and the larger economy is already well understood. However, there is little information about how planning, policy, and programmatic decisions influence contraceptive consumption. Accordingly, this paper established an index which explores the weight program planning, contraceptive delivery, and national policies have on contraceptive consumption. The index was established through a factor analysis which utilized monthly indicators from the dissemination of a novel contraceptive product called Sayana Press® in twelve developing countries. Results …

The Effects Of State Tax Reform On Tax Revenue Volatility, Ryan Brown

MPA/MPP/MPFM Capstone Projects

Recent literature has established that state tax revenues have grown significantly more volatile relative to previous decades. Consequently, this is a growing concern for state policymakers who increasingly need stable revenue sources to meet spending obligations. In this paper, the consequences of comprehensive state tax reforms on subsequent tax revenue volatility are studied using the reforms of Utah (2007) and North Carolina (2013) as case studies. Using a synthetic control methodology, graphical evidence suggests that North Carolina’s tax reform resulted in lower subsequent revenue volatility, but that Utah’s reform likely did not have such an effect on revenue volatility.

A Multiple Case Study Of Music Therapists' Perceptions Of Vocal Health, Emily Rush

Theses and Dissertations--Music

As professional voice users, music therapists should be aware of their vocal health and the risks for developing vocal problems through habitual vocal use. Vocal abuse refers to vocal activities such as yelling, singing with poor technique, and shouting which cause the laryngeal mechanism to not function optimally. Although many music therapists are at risk for vocal abuse, to my knowledge, no researchers have looked at how music therapists are using their voices. The purpose of this qualitative study was to better understand music therapists’ perceptions of their vocal health and vocal health training. I used a multiple case study …

Improving Kentucky's Winter Wheat And Double Crop Soybean Rotation, Katherine Susan Rod

Theses and Dissertations--Plant and Soil Sciences

The winter wheat double crop soybean rotation is an economically viable rotation for Kentucky farmers. Recent decreases in commodity prices has warranted the need to evaluate intensive management practices that can increase yields and profitability in this crop rotation. There were three goals of this dissertation: 1.) identify management practices that would decrease deoxynivalenol (DON) in harvested wheat grain and increase wheat heading and anthesis uniformity, 2.) evaluate double crop soybean planting timing and identify intensive management practices to increase seed yield, and 3.) determine the profitability of these management options. These studies were conducted in Princeton KY between 2016 …

The Impact Of Ryegrass On A Fragipan Soil, Keegan Patrick Smith

Theses and Dissertations--Plant and Soil Sciences

Fragipans are soil horizons which negatively impact row crop yields due to their cemented nature. Annual ryegrass has been proposed as a cover crop to help remediate these dense horizons. The objectives of this study were to (1) evaluate potential ryegrass root exudates and their ability to solubilize proposed fragipan cementing agents, aluminum (Al), iron (Fe), and silica (Si) in stirred-batch reactor studies; and (2) evaluate annual ryegrass’ ability to remediate the fragipan through an 8-week greenhouse growth study using non-destructive, mini-rhizon samplers installed on soil cores for in situ pore water sampling, and non-invasive soil porosity calculations using X-ray …

Extracting Secondary Metabolites From Bacterial Endophytes To Suppress Or Promote Sweet Sorghum And Weeds, Mohammad R. Alsabri

Theses and Dissertations--Plant and Soil Sciences

Endophytic bacteria are ubiquitous in agricultural settings and have the potential to drastically affect plant growth both positively and negatively. These complex relationships play a key role in plant nutrition and are therefore of great interest to the agricultural community and beyond. With my dissertation work, I have had the opportunity to examine the relationship between endophytic bacteria and plants in various ways. The first part of my dissertation investigated how the microbial diversity found in soil affects the below- and above-ground traits of Sorghum bicolor. In the second section, I focused on a particular strain of bacteria that …

Acute Sensitivity And Tolerance To Alcohol As Predictors Of At-Risk Drinking, Holley Allen

Theses and Dissertations--Psychology

Laboratory studies have reliably shown that reduced sensitivity to alcohol’s subjective intoxicating effect is associated with heavier drinking. More recently, there has been research to suggest that heightened sensitivity to the disinhibiting effects of alcohol might also contribute to at-risk drinking. Most research on the acute effects of alcohol has focused on drinking magnitudes averaged across participants with little attention to how individual differences influence abuse potential. This study overcomes previous limitations by testing the degree to which individual differences in acute sensitivity and tolerance to the subjective intoxicating and disinhibiting effects of alcohol predict drinking behavior in a large …

Mental Contamination, Coping, And Ptsd Symptom Severity Following Sexual Trauma, Jordyn M. Tipsword

Theses and Dissertations--Psychology

Mental contamination (MC) – an internal sense of dirtiness experienced without contact with a contaminant – has been linked to PTSD symptoms among sexual trauma survivors. However, existing work has been limited to cross-sectional or quasi-experimental designs – precluding conclusions concerning the directionality of associations among PTSD symptoms and MC – and little work has examined potential mediators of those associations. The present study utilized a prospective design to evaluate the directionality of associations between MC and PTSD symptoms and the role of avoidance and approach coping in mediating those associations. Participants included 41 women with a history of sexual …

Cancer Patients’ Tobacco Use And Tobacco Treatment Referral Response: Implementation Outcomes At A National Cancer Institute- Designated Cancer Center, Tia Borger

Theses and Dissertations--Psychology

Smoking after cancer diagnosis is linked to cancer-specific and all-cause mortality among other adverse outcomes. Yet, 10-20% of U.S. cancer survivors are current smokers. Implementation of evidence-based tobacco treatment in cancer care facilities is widely recommended, yet rarely accomplished. This study focuses on the early outcomes of a tobacco treatment program integrated within an NCI-designated cancer center. Participants consist of 26,365 patients seen at the cancer center during the first 18 months of implementation. The study is a retrospective chart review of patients’ tobacco use, and among current users, patients’ treatment referral response. Over 99% of patients were screened for …

Modulation Of Epileptogenesis: A Paradigm For The Integration Of Enzyme-Based Microelectrode Arrays And Optogenetics, Corwin R. Butler, Jeffery A. Boychuk, Francois Pomerleau, Ramona Alcala, Peter Huettl, Yi Ai, Johan Jakobsson, Sidney W. Whiteheart, Greg A. Gerhardt, Bret N. Smith, John T. Slevin

Physiology Faculty Publications

BACKGROUND: Genesis of acquired epilepsy includes transformations spanning genetic-to- network-level modifications, disrupting the regional excitatory/inhibitory balance. Methodology concurrently tracking changes at multiple levels is lacking. Here, viral vectors are used to differentially express two opsin proteins in neuronal populations within dentate gyrus (DG) of hippocampus. When activated, these opsins induced excitatory or inhibitory neural output that differentially affected neural networks and epileptogenesis. In vivo measures included behavioral observation coupled to real-time measures of regional glutamate flux using ceramic-based amperometric microelectrode arrays (MEAs).

RESULTS: Using MEA technology, phasic increases of extracellular glutamate were recorded immediately upon application of blue light/488 nm …

This manuscript provides a detailed review of published literature on LCNEC of gynecological origin. We performed a PubMed search for material available on gynecologic LCNEC. We analyzed 104 unique cases of gynecologic LCNECs, of which 45 were cervical primary, 45 were ovarian, 13 were uterine, and 1 was vaginal. A total of 45 cases of cervical LCNEC were identified with a median age of 36 years. Median overall survival was 16 months. We identified 45 ovarian LCNEC cases in the published literature with …

Fourier Transform Infrared Spectroscopy (As A Rapid Method) Coupled With Machine Learning Approaches For Detection And Quantification Of Gluten Contaminations In Grain-Based Foods, Abuchi Godswill Okeke

Theses and Dissertations--Biosystems and Agricultural Engineering

Cross-contamination between food grains during harvesting, transportation, and/or food processing is still a major issue in the food industry. Due to cross-contact with gluten-rich grains (wheat, barley, and rye grains), gluten can get into food that’s naturally free from gluten and thus may not be safe for consumption for people susceptible to gluten-related disorders such as celiac disease, wheat allergy, gluten intolerance or sensitivity. The conventional method of gluten detection is cumbersome, time-consuming, and requires well-trained personnel. Therefore, there is a need for a rapid and equally effective technique to authenticate gluten contamination in foods. This research work explored the …

Home Rule, Local Autonomy, And Municipal Government Behavior, Xin Chen

Theses and Dissertations--Public Policy and Administration

This dissertation focuses on relationships between state and local governments. Of particular interest in this project is how the shift of power from the state to local governments changes local governments’ performance. This dissertation is comprised of four chapters. The first chapter briefly introduces the motivation and organization of the dissertation. The second chapter reviews the three state-imposed fiscal institutions—home rule, debt limitations, and tax and expenditure limitations, across states. While previous studies have looked at specific institutions, few studies have comprehensively reviewed the status of those institutions across states. This chapter attempts to fill this gap by comprehensively scrutinizing …

Structural And Lexical Methods For Auditing Biomedical Terminologies, Rashmie Abeysinghe

Theses and Dissertations--Computer Science

Biomedical terminologies serve as knowledge sources for a wide variety of biomedical applications including information extraction and retrieval, data integration and management, and decision support. Quality issues of biomedical terminologies, if not addressed, could affect all downstream applications that use them as knowledge sources. Therefore, Terminology Quality Assurance (TQA) has become an integral part of the terminology management lifecycle. However, identification of potential quality issues is challenging due to the ever-growing size and complexity of biomedical terminologies. It is time-consuming and labor-intensive to manually audit them and hence, automated TQA methods are highly desirable. In this dissertation, systematic and scalable …

The 2016 Epilepsy Innovation Institute (Ei2) community survey reported that unpredictability is the most challenging aspect of seizure management. Effective and precise detection, prediction, and localization of epileptic seizures is a fundamental computational challenge. Utilizing epilepsy data from multiple epilepsy monitoring units can enhance the quantity and diversity of datasets, which can lead to more robust epilepsy data analysis tools. The contributions of this dissertation are two-fold. One is the implementation of a temporal query for epilepsy data; the other is the machine learning approach for seizure detection, seizure prediction, and seizure localization. The three key components of our temporal …

The Applicability Of The Partners For Change Outcome Management System For Psychotherapy In South Korea: Exploring Korean Therapists’ Experiences, Sang-Hee Hong

Theses and Dissertations--Educational, School, and Counseling Psychology

The introduction of psychotherapy approaches to another culture may require adjustments, such as cultural adaptation (Benish, Quintana, & Wampold, 2011; Griner & Smith, 2006). Unique features of a specific cultural group, such as a native language and traditional cultural values may interfere with new approaches. Although a client feedback system, the Partners for Change Outcome Management System (PCOMS; Miller, Duncan, Sorrell, & Brown 2005) has been established as an evidence-based treatment approach with clients in the United States, little has been examined on its utility in Korean psychotherapy. Therefore, the aim of this study was to investigate the applicability and …

Poverty And Nonprofits: Investigating The Relationship Between Poverty And Nonprofit Activity In The United States, Megan Combs

MPA/MPP/MPFM Capstone Projects

In order to better understand our society and institutions, we can look at the relationships between institutions, social infrastructure, and human conditions. Social and institutional networks can influence the flow of resources on a scale that individuals cannot. These structures can perpetuate or alleviate social and human conditions but, alternatively, social conditions can mobilize and influence institutional structures. As systemic poverty remains a social issue, various US programs and forms of aid continue to be delivered despite limiting and varying levels of success. One such mode of aid is provided by nonprofits. Studies have shown that nonprofits empirically do very …

High Demand Labor Sectors And College Enrollment: A Preliminary Analysis Of The Work Ready Kentucky Scholarship (Wrks), Jillian Frost

MPA/MPP/MPFM Capstone Projects

States have taken a variety of approaches to improving educational investment in the labor market and increasing educational attainment statewide. One such approach is the idea of target sectors – identifying high demand and high growth industries to direct business and educational investment across the state. Since 2011, the Commonwealth of Kentucky has utilized target sectors to identify high demand high wage occupations in order to drive labor force participation, employment, and educational alignment. To combat projected employee shortages in the identified target sectors and low educational attainment across the state, Kentucky launched the Work Ready Kentucky Scholarship (WRKS) program …

Cost-Benefit Analysis Of Composting At The University Of Kentucky, Jennifer Sutton

MPA/MPP/MPFM Capstone Projects

This study is a cost-benefit analysis (CBA) of the University of Kentucky’s composting program. Food waste is collected from two major dining facilities on campus and composted at the university’s C. Oran Little Research Center in Woodford County. This CBA only considers the direct accounting costs of the program. Three models were developed and analyzed. Ultimately, all three models resulted in a deficit over the life of the project. However, it is important to note that benefits were likely understated because this CBA did not take into consideration the environmental or social benefits that exist from a composting program at …

The Pragmatist’S Call To Democratic Activism In Higher Education, Eric Thomas Weber

Educational Policy Studies and Evaluation Faculty Publications

This essay defends the Pragmatist’s call to activism in higher education, understanding it as a necessary development of good democratic inquiry. Some criticisms of activism have merit, but I distinguish crass or uncritical activism from judicious activism. I then argue that judicious activism in higher education and in philosophy is not only defensible, but both called for implicitly in the task of democratic education as well as an aspect of what John Dewey has articulated as the supreme intellectual obligation, namely to ensure that inquiry is put to use for the benefit of life.

Measuring Change: Prediction Of Early Onset Sepsis, Aric Schadler

Theses and Dissertations--Statistics

Sepsis occurs in a patient when an infection enters into the blood stream and spreads throughout the body causing a cascading response from the immune system. Sepsis is one of the leading causes of morbidity and mortality in today’s hospitals. This is despite published and accepted guidelines for timely and appropriate interventions for septic patients. The largest barrier to applying these interventions is the early identification of septic patients. Early identification and treatment leads to better outcomes, shorter lengths of stay, and financial savings for healthcare institutions. In order to increase the lead time in recognizing patients trending towards septicemia …

An Exploratory Case Study: Using Web-Based Micro Videos As A Parent Involvement Tool To Support Families With Preschool Age Children In Early Numeracy Development, Jamie Thompson

Theses and Dissertations--Curriculum and Instruction

The United States Federal Government recognized the importance of parent involvement in the No Child Left Behind Act (NCLB) of 2001. Parent involvement has been associated with lower grade retention rates (student repeating a grade level), higher graduation rates, and higher student achievement rates. Reported obstacles to parent involvement include lack of child development knowledge and time constraints. In early childhood, a major focus has been placed on early literacy skills. However, studies that involve early numeracy skills especially in the home environment are lacking. Therefore, this study attempted to fill that void. An instrumental exploratory case study research design …

Ionic Bonding Curriculum Unit: An Electrostatic Framework, Mary Frank Lamar

Theses and Dissertations--Education Sciences

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 spatial skills tested before and after learning about the ionic bond using the Purdue Spatial Visualization-Rotations Test (PVST-Rot; Bodner & Guay, 1997). Students’ content was …

Stretching The Dollar: Exploring The Lived Experiences, Multiple Identities, And Class Politics Of Poor And Working-Class Women At The University Of Kentucky, Rachael Deel

Theses and Dissertations--Education Sciences

In the climate of prioritizing retention and pressure to move an increasingly diverse undergraduate population towards degree, it is critical that educational research consider the multiple, overlapping identities of students and how that influences their experiences on campus. The number of low-income students entering four-year institutions is growing each year, including at the University of Kentucky. This study aims to extend our understanding of social class beyond the material and focus on the affective dimensions of class including language, comportment, and leisure activities in an effort to better understand how poor and working-class women contend with the constraints they encounter …
