Predicting Biologic Nonadherence In Inflammatory Bowel Disease Using Machine Learning Models, Christian Rhudy

Theses and Dissertations--Clinical and Translational Science

Inflammatory bowel disease is a chronic relapsing-remitting disease of the intestinal tract affecting approximately 0.5% of the population in the US. Moderate to severe inflammatory bowel disease is managed with biologic therapies to induce and maintain remission, however nonadherence to biologics occurs in and estimated 16.9% and 45% of patients. Nonadherence to biologics can increase the risk of disease flares, emergent healthcare utilization, and surgical intervention. While numerous factors have been associated with biologic nonadherence, there are limited resources for prospectively assessing patient-specific risk of biologic nonadherence. Accordingly, objective of this work is to develop machine learning methods of predicting …

“A Safe Place”: Exploring Black Couples’ Perceptions Of Black Love And Relationship Coping In The Context Of Their Lived Experiences With Racism, Melinda Murdock

Theses and Dissertations--Family Sciences

Historically, Black couples have not been studied within the context of their lived experiences as it relates to the effects of racism on relationship health. Only in the last decade have relationship scholars begun to consistently link racism-related stressors to relationship processes and outcomes. Despite the growing literature, recent studies are primarily quantitative in method and rely on samples, theoretical models, and measures that predominantly represent White couples’ experiences. It remains unclear how Black couples’ perceptions of love and relationship coping lead to resilient outcomes despite the negative effects of racism.

Therefore, the goal of the present study is to …

Diet Of Adult Ladybird Beetle Hosts Modifies The Postdiapause Development Of The Parasitoid Dinocampus Coccinellae (Hymenoptera: Braconidae), John J. Obrycki

Lady Beetle Research Data

Our study showed that under natural conditions the rate and speed of postdiapause emergence by overwintering larvae of the endoparasitic wasp, Dinocampus coccinellae (Schrank) is enhanced when its ladybird beetle host Coleomegilla maculata (DeGeer) receives a nutritious (proteinaceous) diet during late winter and early spring. Living aphid prey provided during April and May yielded the fastest rates of D. coccinellae postdiapause development, followed by an artificial protein/carbohydrate diet and flowering (pollen-producing) heads of dandelion. D. coccinellae development was slowest when hosts received only sugar water or water alone. These results indicate that there is an interaction during late dormancy between …

Voltage And Var Control And Real-Time Digital Simulator-Based Protection System Testing For Power Distribution Systems, Gaurav Yadav

Theses and Dissertations--Electrical and Computer Engineering

Rising power demand calls for electric distribution systems to manage peak load. One option is reducing feeder voltage, which lowers voltage-dependent load demand and may also reduce energy usage. The technique, known as Conservation Voltage Reduction (CVR), may operate independently or within a volt/var control system. This dissertation examines CVR factor calculation using measurements collected at the substation, and proposes a curve-fitting and artificial neural network method to estimate active power losses using input active power, reactive power, and substation voltage. As utilities integrate more inverter-based resources (IBRs) to support increasing demand, rapid voltage fluctuations arise due to the intermittent …

Influence Of Naturalistic Language Intervention On Child Communication And Engagement, Olivia R. Abate

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

The purpose of this study is to parallel naturalistic instructional contexts that often occur during caregiver-child interactions (e.g., one-to-one arrangement during play) to learn more about how children respond when prompting is introduced compared to responsive interaction strategies alone or with environmental arrangement strategies. This exploratory study was designed to evaluate the potential differential effects within an ATD, comparing RI alone, RI + EA, and RI + MP on joint engagement, communication acts, and interfering behaviors. This study is ongoing and lacks results for communication acts. Preliminary results supported and contradicted aspects of the hypothesis: joint engagement would occur at …

New Insights Into The Ovulatory Process In The Human Ovary, Misung Jo, Mats Brännström, James W. Akins, Thomas E. Curry

UK CARES Faculty Publications

BACKGROUND: Successful ovulation is essential for natural conception and fertility. Defects in the ovulatory process are associated with various conditions of infertility or subfertility in women. However, our understanding of the intra-ovarian biochemical mechanisms underlying this process in women has lagged compared to our understanding of animal models. This has been largely due to the limited availability of human ovarian samples that can be used to examine changes across the ovulatory period and delineate the underlying cellular/molecular mechanisms in women. Despite this challenge, steady progress has been made to improve our knowledge of the ovulatory process in women by: (i) …

German Cockroach Allergen Mitigation, Olivia Katz

Theses and Dissertations--Entomology

German cockroaches (Blatella germanica L.) remain one of the most challenging indoor pests to manage, due in large part to their cryptic nature, rapid reproduction, and resistance to insecticides. Because of their close proximity to humans, they also pose several serious health threats, including the production and dissemination of several potent allergens linked to asthma development and exacerbation. Given the risks associated with cockroach allergens, we examined the longevity of two distinct cockroach allergens (Bla g 1 and Bla g 5) in the home environment and the efficacy of cleaners at removing these allergens. Our findings show that Bla …

Including Black Farmers, Excluding Pests: Perspectives On Participation In The Cooperative Extension Service, Briana Bazile

Theses and Dissertations--Entomology

In recent years, the U.S. Department of Agriculture has faced renewed scrutiny for documented discrimination against Black farmers, yet far less attention has focused on its century-old partner in public service delivery, the Cooperative Extension Service (CES). This gap is especially notable considering 1) federal parity mandates extant since 1972 in response to significant disparities between Black and White constituents and staff,2) public commitments to Diversity, Equity & Inclusion in 2020 and, 3) the contributions of Black leaders at the origins of CES, at Tuskegee University in the late nineteenth century. Using the Kentucky Cooperative Extension Service (KYCES) as a …

Seasonal Variation Of The Stream’S Autogenic Sediment Transport Regime, Melissa Beckman

Theses and Dissertations--Civil Engineering

This thesis investigates the autogenic sediment transport regime in a low-gradient stream system in the inner bluegrass region of central Kentucky, USA The seasonality of sediment transport seasonality was not well addressed in prior research for baseflow and low flow periods, to our knowledge, due to the assumption that low flows do not account for considerable fluid transport capacity to move sediment. The hypothesis is that during the autogenic regime the sediment transport in the low-gradient system is being driven by geophysical, biogeochemical, and biological processes. We hypothesize that crayfish are one mechanical driver of sediment transport during these periods. …
