Characterization And Use Of Pathogen Specific Bacteriophages To Reduce The Viability Of Escherichia Coli O157:H7 Contamination On Fresh Produce, Badrinath Vengarai Jagannathan

Theses and Dissertations--Animal and Food Sciences

Fresh produce is one of the most common sources of food-borne outbreaks, involving various pathogenic microorganisms such as Escherichia coli. Recent outbreaks have clearly shown that post-harvest washing has limited effectiveness on decontaminating produce and may contribute to cross-contamination of produce due to various limitations. Excessive use of sanitizers and antibiotics has also led to the development of many antibiotic-resistant strains of bacteria that have made the food industry more vulnerable.

Bacteriophages are a bacterial viruses that can selectively infect and replicate within bacteria leading to cell lyse and death. Bacteriophages have become widely recognized due to their ability …

The Economics Of Milk Quality Management Practices And Milk Pricing In Simulated United States Dairy Herds, Derek Thomas Nolan

Theses and Dissertations--Animal and Food Sciences

Mastitis is considered one of the most common and costly diseases in the dairy industry. Intramammary infection status at a herd level is measured using somatic cell count (SCC). Understanding the total cost of an elevated somatic cell count can help influence dairy farmers to lower SCC and select management practices to produce higher quality milk. The first objective of our research was to determine if the cost of an elevated somatic cell count to farms can be decreased through the adoption of management practices with varying expenses. Using stochastic simulation modeling, the adoption of three differently priced management practices …

Effects Of An Anchored Career-Focused Curriculum On The Knowledge And Attitudes Of At-Risk High School Students, Megan E. Jones

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Students with disabilities (SWD) face an unfavorable employment future because many drop out of school at a disproportionate rate. The employment outlook for SWD who graduate from high school is also a concern because current studies show that only about half of them find jobs. In addition, most jobs they do find are entry level and low paying. One predictor of post-secondary success is career awareness. The purpose of this study was first to develop a curriculum especially designed for teaching career awareness of SWD and then to test its effects with a pretest-posttest randomized trial. Results indicated that the …

Multi-Modal Medical Imaging Analysis With Modern Neural Networks, Gongbo Liang

Theses and Dissertations--Computer Science

Medical imaging is an important non-invasive tool for diagnostic and treatment purposes in medical practice. However, interpreting medical images is a time consuming and challenging task. Computer-aided diagnosis (CAD) tools have been used in clinical practice to assist medical practitioners in medical imaging analysis since the 1990s. Most of the current generation of CADs are built on conventional computer vision techniques, such as manually defined feature descriptors. Deep convolutional neural networks (CNNs) provide robust end-to-end methods that can automatically learn feature representations. CNNs are a promising building block of next-generation CADs. However, applying CNNs to medical imaging analysis tasks is …

Holistic Resilience Quantification Framework Of Rural Communities, Amanda Melendez

Theses and Dissertations--Civil Engineering

Communities need to prepare for anticipated hazards, adapt to varying conditions, and resist and recover rapidly from disturbances. Protecting the built environment from natural and man-made hazards and understanding the impact of these hazards helps allocate resources efficiently. Recently, an indicator-based and time-dependent approach was developed for defining and measuring the functionality and disaster resilience continuously at the community level. This computational method uses seven dimensions that find qualitative characteristics and transforms them into quantitative measures. The proposed framework is used to study the resilience of rural communities’ subject to severe flooding events. Harlan County in the Appalachian region is …

Parenting From Prison: Perceptions Of Incarcerated Parents' Ability And Influence, Gabrielle Hadorn

Theses and Dissertations--Family Sciences

Incarcerated parents are at a substantially higher risk for losing their legal right to parent than the general public. This study assessed implicit perceptions and biases that may play a role in these legal decisions, specifically the perceptions of incarcerated parents’ ability to parent and influence their children’s lives. Court appointed special advocate (CASA) volunteers’ (N = 242) perceptions of incarcerated parents based on the parents’ personal characteristics, characteristics of their children, and characteristics of their criminal activity were assessed through a true-experiment design. Ordinal regression analyses revealed that age of child, level of violence in the crime committed, and …

Use Of Survey Data To Guide The Development Of Best Practices For Instruction For The Recruitment Of Volunteer Firefighters, Jeffrey Taylor Kimble

Theses and Dissertations--Curriculum and Instruction

The number of calls for service by firefighters has increased by over three times since the 1980s while during the same time, the numbers of firefighters per population has decreased. The increase in the number of calls for service by fire departments is further complicated by that fact that nearly 70% of the firefighters who respond to these calls are volunteers. Further, the number of training hours to become a certified firefighter has also increased. Complicating the issue more is a decrease overall of volunteerism in general in the United States. Increased demand for calls for service, more demanding training …

Fix Society, Please: Three Papers On The Mental Health Treatment, Social Support Resources, And Suicidology Of Transgender And Gender Diverse Adults, Annie Snow

Theses and Dissertations--Social Work

Despite their frequent utilization of mental health resources, transgender and gender diverse (TGD) adults are more likely than their cisgender counterparts to attempt suicide. While this phenomenon may inspire a myriad of explanations, the present dissertation is interested in two exploratory ideas: namely, that 1) mental health professionals may be failing their TGD clients, and 2) traditional mental health paradigms may be myopically inadequate. Paper 1 addresses the first issue by considering TGD experiences of active discrimination by mental health professionals. In addition to investigating the prevalence of abuse, this paper analyzes how intersectionality of oppression plays a role in …

Kinship Care Providers: Exploring The Relationship Of Child Temperment, Combined Factors Of Provider’S Relationship To Primary Parent And Reason For Placement, And Intensity Of Parenting Tasks To Parenting Stress, Shelagh Larkin

Theses and Dissertations--Social Work

In the United States some 2.3 million children, or 3.1 % of all children, live with relatives or non-relatives in foster care or informal care situations outside the foster care system (Radel et al., 2016). These types of placements are called kinship and result from a variety of issues. Focusing on kinship care providers is important given that placement with strangers is stressful and even traumatic for a child (Vandivere et al., 2012). Vandivere et al. (2012) determined that children in kinship care, such as with grandparents, have better outcomes than children in non-kinship foster care. However, providers experience a …

Optimizing Monarch Butterfly And Bee Conservation Efforts In The Urban Landscape, Adam M. Baker

Theses and Dissertations--Entomology

The eastern migratory population of monarch butterflies (Danaus plexippus) is in serious decline. Most of the efforts to conserve this iconic insect focus on habitat restoration in the US Midwest. Often overlooked are small butterfly-centric gardens that can act as stepping stones between urban and rural areas. These studies aim to optimize the conservation value of such gardens.

Eight milkweed (Asclepias) species varying in height, form, and leaf shape were compared over two years in a common-garden experiment. I measured milkweed growth, rhizome spread, and bloom periods, conducted bi-weekly counts of monarch eggs and larvae, evaluated …

College Students Mandated To Substance Use Courses: An Exploration Of Age-Of-Onset, Perceived Norms, And The Theory Of Planned Behavior, Benjamin Neil Montemayor

Theses and Dissertations--Education Sciences

Every year, college campuses report alcohol and other drug (AOD) policy violations as the most frequent reason students receive disciplinary referrals and, thus, are mandated to programming. This dissertation focused on exploring characteristics of students mandated to intervention programming in order to provide recommendations for future programs. This dissertation includes three studies involving students enrolled in mandated intervention programming: (1) a systematic review of the effectiveness of mandated programs in reducing cannabis or other drug use, (2) an examination of the differences between early- and late-onset alcohol and cannabis users, and (3) an exploration of perceived norms, and the Theory …

Effect Of Socioeconomic And Demographic Factors Of Driver Residence On Crash Occurrence, Shraddha Sagar

Theses and Dissertations--Civil Engineering

In the U.S., road traffic crashes are a leading cause of death. Crash data from the state of Kentucky shows that the per capita crash rates and crash-related fatalities were higher than the national average for over a decade. In effort to explain why the U.S. Southeast experiences higher crash rates than other regions of the country, previous research has argued the region’s unique socioeconomic provide a compelling explanation. Taking this observation as a starting point, this study examines the relationship between highway safety and socioeconomic characteristics using an extensive crash dataset from Kentucky.

The primary goal of this research …

Development Of A Robust Treatment Delivery Framework For Stereotactic Body Radiotherapy (Sbrt) Of Synchronous Multiple Lung Lesions, Lana Catherine Critchfield

Theses and Dissertations--Radiation Medicine

Stereotactic body radiation therapy (SBRT) of lung tumors uses high doses of radiation to deliver high biological effective doses (BED) in very few fractions (1-5). With the use of highly conformal fields to cover the tumor without depositing large doses to non-cancerous structures, this technique has proven time and again to be successful at achieving high local control. However, frequently patients receiving SBRT are elderly with multiple medical comorbidities who may not tolerate long treatment times. Furthermore, many patients present with oligometastatic or multiple primary lung tumors. The success of SBRT on oligometastatic lung disease relies on physician experience with …

Time Spent Exercising And Obesity: An Application Of Lewbel’S Instrumental Variables Method, Charles J. Courtemanche, Joshua C. Pinkston, Jay Stewart

Institute for the Study of Free Enterprise Working Papers

This paper examines the role physical activity plays in determining body mass using data from the American Time Use Survey. Our work is the first to address the measurement error that arises when time use during a single day—rather than average daily time use over an extended period—is used as an explanatory variable. We show that failing to account for day-to-day variation in activities results in the effects of time use on a typical day being understated. Furthermore, we account for the possibility that physical activity and body mass are jointly determined by implementing Lewbel’s instrumental variables estimator that exploits …

Touch Sanitation: Maintenance Art As Ecofeminism, Haley Drake

Oswald Research and Creativity Competition

In Mierle Laderman Ukeles’ Touch Sanitation Performance (1979-1980), the artist shook hands with over 10,000 trash collectors from the New York City Sanitation Department. As a self-proclaimed “maintenance artist,” she compared the domestic maintenance work of archetypal mothers to the public maintenance work of waste management crews, illuminating the analogous marginalization of the two groups. In order to further analyze Ukeles’ maintenance art, this paper will investigate the general repugnance toward sanitation work while engaging the approaches to feminist and environmentalist thought present in Julia Kristeva’s “Powers of Horror,” William Rathje’s theories of garbology, and ecofeminist theory. This analysis finds …

Kentucky’S Primary Care Workforce: Current Status And Output Of New Trainees January 2020 Update, Kevin A. Pearce, Sydney P. Thompson, Frances J. Feltner

Center of Excellence in Rural Health Workforce Reports

Primary care is the backbone of American healthcare. Primary care (PC) physicians are especially cost-effective in preventing and managing illness and disability, and prolonging years of quality life. They also contribute significantly to the economy of their communities. Primary care shortages across the Commonwealth are severe. Kentucky ranks 43^rd in the USA for its number of PC physicians per 100,000 people. The Commonwealth would have to add 246 primary care physicians annually to reach the US median by the end of 2029. Kentucky produces and retains only about 55 new PC physicians per year, recruiting 55 to 60 more …

Neurosurgery Faculty Publications

BACKGROUND: Early changes in acid/base and electrolyte concentrations could provide insights into the development of neuropathology at the onset of stroke. We evaluated associations between acid/base and electrolyte concentrations, and outcomes in permanent middle cerebral artery occlusion (pMCAO) model.

METHODS: 18-month-old male and female Sprague-Dawley rats underwent pMCAO. Pre-, post- (7 min after occlusion), and at 72 hr of pMCAO venous blood samples provided pH, carbon dioxide, oxygen, glucose, hematocrit, hemoglobin, and electrolyte values of ionized calcium, potassium, and sodium. Multiple linear regression determined predictors of infarct and edema volumes from these values, Kaplan-Meier curve analyzed morality between males and …

The Loch Ness Monster, Haggis, And A Lower Voting Age: What American Can Learn From Scotland, Joshua A. Douglas

Law Faculty Scholarly Articles

This Article, prepared for an American University Law Review

symposium, explores what the United States can learn from Scotland's experience

in lowering the voting age to sixteen. The minimum voting age in American

elections seems firmly entrenched at eighteen, based in part on the Twenty-Sixth

Amendment, which prohibits states from denying the right to vote to anyone aged

eighteen or older. Yet the conversation about lowering the voting age to sixteen,

at least for local elections, has gained steam in recent years. The debate in

America, however, is nascent compared to the progress in Scotland, which

lowered the voting age …

Outlaws, Pirates, Judges: Judicial Activism As An Expression Of Antiauthoritarianism In Anglo-American Culture, Beau Steenken

Law Faculty Scholarly Articles

This article will argue that the rejection of what scholars otherwise

view as controlling legal authority lies at the heart of judicial activism.

Furthermore, it will argue that judicial activism itself channels the

antiauthoritarian current in American culture (and in English culture

predating its importation to America). Part II will examine the extensive

scholarly writings already existing on judicial activism in order to identify

common themes and to explore to what extent scholars have arrived at a

consensus definition of judicial activism. Part III will then show that

judicial activism may better be understood within the context of law as …

From Petri Dish To Main Dish: The Legal Pathway For Cell-Based Meat, Brian P. Sylvester, Nathan A. Beaver, Kara Schoonover, Jonathan I. Tietz

Kentucky Journal of Equine, Agriculture, & Natural Resources Law

Meat grown outside an animal is no longer simply science fiction, and the market is poised for introduction of a variety of so-called cell-based meat products. Commercializing these products will require a clear regulatory path forward. In this Article, we explore that legal pathway. We introduce the concepts of cellular agriculture and cell-based meat, including the science, the state and history of the industry, and the general regulatory background, in which the USDA and FDA are the major players. Further, we explore in particular regulatory aspects of food safety and labeling in the context of cell-based meat. Overall, we contend …
