Two Essays on Governments Devolving Fiscal Authority to Lower-Level Actors

Jinsol Park
Over the past decades, there have been efforts across the globe to break the grip of the centralized power of government and devolve authority to lower-level actors. The devolution of authority in the governance system can take place in various ways: the central government can devolve authority, responsibility, and functions to local governments; or a local government can delegate its authority to make policy decisions to the citizenry, for example, as a form of public...

THE TRUST-BASED CLASSROOM

Ellen Prasse
Many current social and emotional learning (SEL) programs cite building trust as a key factor to an effective SEL program. Despite these references, however, they often lack an emphasis on teaching methods of building trust between students and their peers, the teacher, and the environment. Instead they focus on a specific aspect of teaching like the procedural practices of Responsive Classroom or communication and open-mindedness as in Open Circle. Explicitly building trust, however, could create...

WORK-RELATED CHANGES IN THE TRUNK STIFFNESS OF NURSING PERSONNEL

Clare Tyler
Low back pain (LBP) is a significant issue related to spinal stability and, therefore, to trunk stiffness. Due to the nature of their work, nursing personnel are exposed to potential risk factors for LBP, such as lifting and trunk flexion, which have been reported in the literature to lead to decreases in trunk stiffness. Consequently, the purpose of this study was to investigate potential occupational effects on the trunk stiffness in nursing personnel. Twenty-four nursing...

Comparison of Differential Effects of Interpolated and Intermittent Reinforcement on Extinction Resistance

Cara D. Baxter
Schedules of reinforcement explain when a reinforcer may be delivered. Among the different schedules exists continuous (CRF), intermittent (INT), and extinction (EXT). When employing a CRF, reinforcement is delivered following every occurrence of the target response. An INT schedule includes varying the delivery of reinforcement. While both of these schedules include the delivery of reinforcement, EXT means that reinforcement is no longer delivered for the target response (Lee & Belfiore, 1997). Studies have shown that...

Coaching Caregivers in Rural Communities on Naturalistic Strategies via Telehealth

Stevie L. Ogburn
Naturalistic strategies have been shown in research to promote expressive language in children by embedding opportunities for learning trials during routines and activities. Efforts to promote expressive language development are often focused on training caregivers in implementing naturalistic strategies in their child’s typical daily routine. Coaching is a consistently effective training practice to prepare family members to implement the naturalistic strategies. While coaching has been shown to be effective, the recommended time requirement could be...

MODELING ENERGY FLOWS IN FLOATING IN-POND RACEWAYS UTILIZING SOLAR POWER BACK-UP

Bo Smith
The In-pond Raceway (IPR) is a novel option for production aquaculture, depending on water moving devices to provide constant flow. Device failure may result in catastrophic fish loss, requiring power backup systems to mitigate risk in case of power outages. Because these systems must be dependable and many suitable locations are remote, off-grid solar photovoltaic (PV) systems with battery storage have been considered since they eliminate need for utility power. Such systems can be hard...

Turbulence Suppression in an Axially Rotating Pipe

Alyn J. Smith
The phenomenon of turbulence suppression in a rotating pipe flow system has been well documented by past research and experimentation. Despite this, the methods that drive this phenomenon have not yet been effectively characterized, especially at higher Reynolds numbers. While many experiments have been performed to better understand swirling turbulent pipe flow, a difficulty that arises is how to test for high levels of rotation without reducing the Reynolds number. This thesis documents the design...

UNDERSTANDING THE EFFECTS OF COMPLEX TOPOGRAPHY ON COVER CROP DYNAMICS AND MAIZE PRODUCTION IN KENTUCKY AGROECOSYSTEMS

Samuel Leuthold
In Central Kentucky, rolling hill cropland presents a number of challenges related to soil sustainability. Increased topographic complexity can lead to increased erosion, inefficient crop nutrient use and increased nutrient loss. Further, grain crop yields can be variable across both space and time in rolling hill fields and are less resilient to changes in weather conditions than flatter, more homogeneous areas. More than 30% of cropland in Kentucky has a slope greater than 3⁰, which...

ACL Injury, a Time Course Study of Transcriptional Changes

Thomas Carter
ACL tear is a common injury in the United States with a significant cost and time burden during recovery; reconstructive surgery often results in weakened quadricep muscle and higher risk of posttraumatic osteoarthritis. Prior research has highlighted cellular derangements within the quadriceps after ACL injury and reconstruction, but the early molecular effectors of cellular dysfunction remain to be identified. To further understand the molecular effectors of quadriceps dysfunction following ACL injury, this study aims to...

Hepatitis B virus middle surface antigen loss promotes clinical variant persistence in mouse models

Junyu Lin, Jing Li, Peilin Xie, Yue Han, Demin Yu, Jia Chen & Xinxin Zhang
Hepatitis B virus (HBV) middle surface antigen (MHBs) mutation or deletion occurs in patients with chronic HBV infection. However, the functional role of MHBs in HBV infection is still an enigma. Here, we reported that 7.33% (11/150) isolates of CHB patients had MHBs start codon mutations compared with 0.00% (0/146) in acute hepatitis B (AHB) patients. Interestingly, MHBs loss accounted for 11.88% (126/1061) isolates from NCBI GenBank, compared with 0.09% (1/1061) and 0.00% (0/1061) for...

Brynnan Dunaway
The prevalence of obesity is greater in rural communities, and current health promotion interventions have not shown broad positive impacts on dietary patterns in these areas. Focusing community-based efforts on unconventional food retailers is a unique avenue to encourage healthier food choices in rural populations. This study used shelf-wobblers to market healthier snack and beverage items at convenience stores (n=5) in a rural Kentucky county. Selection of healthy snacks and beverages from the store inventory...

CHARACTERISTICS OF CERCOSPORA NICOTIANAE WITH REDUCED SENSITVITY TO AZOXYSTROBIN

William Barlow
Burley and dark tobacco production are important to agriculture in Kentucky, worth $145.1 and $94.4 million in 2020, respectively. The price received for a tobacco crop is influenced by leaf quality, determined by multiple characteristics including leaf damage. Frogeye leaf spot (FLS), caused by Cercospora nicotianae, has historically been a minor disease of tobacco. However, when FLS infections reach the upper canopy of tobacco, lesions are seen as damage that negatively influence leaf quality. Fungicides...

Capture of Respirable Dust using Maintenance Free Impingement Screen

NEERAJ GUPTA
Dust produced during mining activities has a detrimental effect on both miners’ health and operations’ safety. There is no definitive treatment for coal miners’ pneumoconiosis (CWP), which is caused by prolonged inhalation of respirable dust. Elevated coal dust concentrations have also been shown to cause several disastrous explosions in the United States and worldwide, resulting in the death of miners and loss of operations. Flooded-bed dust scrubbers are used on all modern-day continuous miners. These...

Application of a Novel Ventilation Simplification Algorithm

Caitlin Strong
Ventilation network analysis is an integral part of maintaining a safe mine environment. Despite its important role, liberties are often taken with the representation of networks in ventilation network analysis software. In order to provide an alternative to heuristic methods used by ventilation engineers, a simplification algorithm has been developed. This algorithm is designed to work as a compliment to ventilation software. Comparisons of original ventilation networks and simplified networks show little to no change...

Investigation of Nitrate Transfer in Karst Basins During Storm Events Using Submersible Underwater Nutrient Analyzers

John Pike
Knowledge of nitrate sources and pathways in karst basins remains incomplete and hinders management of nutrients that cause algae blooms and degrade municipal water supply. However, the increased availability of optical, ultraviolet nitrate sensors allows advancement of nitrate source and transfer for water managers. A concept model is hypothesized for nitrate transfer during hydrologic events and baseflow that considers the multiple porosity of karst. To test the concept model, 15-minute nitrate sensor data is collected...

INFLUENCE OF DIETARY MANIPULATION ON THE RELATIONSHIP BETWEEN TEMPERAMENT MEASURES AND GROWTH IN BEEF CATTLE

Paul Shanks
The influence of dietary factors (including endophyte exposure, phytogenic supplementation, and controlled feeding) on relationships between exit velocity (EV), growth performance in grazing and finishing cattle, and carcass characteristics were explored. Two grazing studies were conducted evaluating EV effects on cattle grazing both toxic and nontoxic endophyte-infected tall fescue. Cattle were followed through two subsequent finishing studies and an additional beef cattle finishing beef cattle study was also conducted. Results from these studies agree with...

SOUTHERN PINE BEETLE-SPECIFIC RNA INTERFERENCE DEMONSTRATES NO EFFECTS ON NONTARGET INSECTS

Hannah Marie Hollowell
The endemic southern pine beetle (SPB), Dendroctonus frontalis Zimmermann, is a highly destructive bark beetle that has devastated coniferous forests of the southern United States for decades. Traditional management strategies have been unable to respond effectively to largescale SPB outbreaks, prompting exploration of novel techniques including RNA interference (RNAi). Double-stranded RNAs (dsRNAs) are effective at triggering gene silencing and inducing mortality in SPB, but determining delivery methods and demonstrating specificity of the treatments is necessary...

ISOLATION BOX TEST (IBT) AND DAIRY CALF PERSONALITY TRAITS RELATIONSHIP WITH PERFORMANCE THROUGH WEANING

Megan Woodrum Setser
Personality tests are utilized to characterize individual differences in personality traits across species. Currently, there is no objective personality test that can be implemented on-farm to measure personality in dairy calves. Measuring personality of youngstock in the dairy industry may allow producers to utilize information on individual differences for management decisions and limit the investment in unfit individuals. The isolation box test is a personality test that has potential to be adapted and utilized for...
