Aggregation Behavior In The Bed Bug, Cimex Lectularius L., Paul D. Baker

Theses and Dissertations--Entomology

The bed bug, Cimex lectularius L., is a common household pest that feeds on the blood of its human hosts. Unlike many other hematophagic arthropods, bed bugs have not demonstrated the ability to vector disease; yet its presence in a household often leads to fear and anxiety amongst its human host victims. Bed bugs spend the majority of their time aggregating in enclosed and hidden locations, making it difficult to detect and eradicate them. One of the significant mediators of aggregation behavior is an aggregation pheromone. The pheromone has been identified to be six chemical compounds, five volatile compounds that …

Management Of Sugarcane Aphid (Melanaphis Sacchari) Using Biological And Cultural Tactics In Kentucky, Nathan Harriman Mercer

Theses and Dissertations--Entomology

In 2013, a new aphid pest of sorghum, the sugarcane aphid Melanaphis sacchari Zehntner (Hemiptera: Aphididae), was found in the southern US, and caused significant yield loss in sorghum. Since then, M. sacchari has spread to most of the sorghum growing regions. Unmanaged populations can cause complete crop loss in grain, forage and sweet sorghum. M. sacchari cannot survive winters without a live plant tissue and must recolonize much of its pest range annually. Sweet sorghum (Sorghum bicolor) is an important crop for many growers in Kentucky, producing $16-25 million a year from its syrup. Biological control of …

Developing Alternative Practices For Management Of Flea Beetles Attacking Eggplant And Leafy Brassicaceous Greens, Robert Brockman

Theses and Dissertations--Entomology

Flea beetles are a challenging pest for many producers of vegetable crops in Kentucky. Chewing numerous small holes in the leaves of their host plants, high flea beetle populations can quickly overwhelm unestablished crops. I tested the efficacy of several alternatives to insecticides within brassicaceous leafy greens and eggplant. Four field trials in 2019 and 2020 compared essential oil sprays, the woven-mesh row cover ProtekNet, the spunbonded row cover Agribon, and reflective silver mulch to an untreated control, a conventional insecticide rotation of dinotefuran and pyrethroids, and an organic insecticide rotation of spinosad and pyrethrins. The silver reflective mulch was …

Voices Of Hope: A Randomized Controlled Trial Of A Peer-Delivered Telephone Recovery Support Program, Alex Elswick

Theses and Dissertations--Family Sciences

Substance use disorder (SUD) is one of the most pervasive public health problems in the United States (US Surgeon General, 2016). Addiction (used synonymously with SUDs here) is associated with an abundance of negative outcomes including reduced quality of life, increased criminal activity, spread of infectious diseases, child neglect, job loss, loss of productivity and much more (US Surgeon General, 2016). Despite the detriment that addiction poses to virtually all facets of society, the addiction treatment paradigm in the United States lags significantly behind the research (Kelly & White, 2011; Laudet & Humphreys, 2013). This current system focuses on intensive, …

Epigenetic Regulation Of Hormone Action In The Red Flour Beetle, Tribolium Castaneum (Herbst), Smitha George

Theses and Dissertations--Entomology

Hormones are the chemical communication signaling molecules released into the body fluid to stimulate target cells of multicellular organisms. Two major hormones, ecdysteroids (20-hydroxyecdysone, 20E) and juvenile hormones (JH), regulate a wide variety of physiological and developmental processes in insects. Therefore, hormones have been extensively studied and are attractive targets for the development of target-specific insect control methods. Recent studies suggest that epigenetics adds another layer of regulation to explain multiple functions of the same circulating hormone in different tissues and at various time points. In my dissertation, I focused on a major post-translational modification, ‘acetylation,’ to elucidate the epigenetic …

Emotional Closeness Within Romantic Relationships: Is There Transmission Between Generations?, Mckenna Diane Fey

Theses and Dissertations--Family Sciences

This study tested the existence of intergenerational transmission of romantic emotional closeness using Galovan and Schramm’s (2018) model of relationship flourishing as a theoretical backbone. Romantic emotional closeness in the present study included intimacy (i.e., self-disclosure), admiration (i.e., appreciation expression), and dyadic coping. Couples among three generations from the Panel of Analysis of Intimate Relationships and Family Dynamics (Brüderl et al., 2013) were examined to test whether romantic emotional closeness in the first generation predicted romantic emotional closeness in the second generation, and whether that of the second generation predicted that of the third. Regressions within a partial latent model …

Race-Related Stress, Resiliency, And Relationship Quality In Black Couples, Melinda Murdock

Theses and Dissertations--Family Sciences

Scholars have historically explained Black marriage patterns of instability and dissolution based on White middle-class models that ignore cultural factors and maintain a narrative of dysfunction. The current study examines resilience in Black couples by exploring mediation effects of attribution and dyadic coping processes on race-related stress and relationship quality. The present study used individual data from 131 middle-income Black couples residing in the South, who self-reported on stress, coping, and relationship quality via online survey. Dyadic Coping was predicted to mediate the relationship between Race-related Stress, Attribution, and Relationship quality. Results indicated that individuals who experienced greater stress from …

Does Parental Stress Influence Parent-Child Sexual Communication?, Kirstie Otto

Theses and Dissertations--Family Sciences

This study shined a light on the impact of parent’s sexual attitudes and parental stress has on parent-child sexual communication. A sample of 203 parents between the ages of 30 and 60 were recruited to complete an online survey about their levels of parental stress, their sexual attitudes, and how often they discuss sexual communication with their adolescents. Beliefs that the responsibility of birth control should be shared between all parties involved, set the foundation that there will be higher levels of parent-child sexual communication. These findings inform therapists about the importance of creating a safe place where families can …

Stress And Cancer Treatment: How A Family’S Adaptability And Cohesion Affects Financial Stress, Emily Marie Johnson

Theses and Dissertations--Family Sciences

According to the American Cancer Society (2019), it is estimated that 1,762,450 new cancer diagnoses occurred in 2019 in the United States. Currently, cancer remains one of the leading causes of death worldwide (American Cancer Society, 2019). As cancer affects the family, roles within the family will shift (e.g., transitioning to a caregiving relationship), causing each family member to adapt. With the costs of cancer steadily increasing, this potentially leaves a devastating impact on the family. When considering family function in terms of Family Systems, John Rolland created the Family Systems Illness Model to explain how families adapt to an …

Implementation of nutrition and pollution curriculum into two week-long summer day camps for youth ages 5-12 years that focus around healthy lifestyles and environmental stewardship has the potential to increase health protective action in this community. This research utilized qualitative interviews of 30 Kids on the Creek Camp attendees to determine the efficacy of the implementation of an active learning lesson to increase EHL by explaining the link between …

The Development Of A Couple Observational Coding System For Computer-Mediated Communication, Martha S. Rackets

Theses and Dissertations--Family Sciences

Many romantic couples integrate text and computer-mediated communication (CMC) into their relationship dynamics, both for general relationship maintenance and for complex dynamics such as problem solving and conflict. Romantic couple dynamics are interactional, dynamic, and sequenced in nature, and a common method for studying interactions of this nature is observational analyses. However, no behavioral or observational coding systems exist that are able to capture text-based transactional couple communication. The main purpose of this dissertation was to develop an observational coding system that can be used to assess sequenced computer- mediated, text-based communication that takes place between romantic partners. This process …

Didactic Marital Mediation: An Alternative Model Of Helping Couples Stay Married, Djidjoho C. Y. Akloubou Gnonhossou

Theses and Dissertations--Family Sciences

Mediation is one of the alternative dispute resolution (ADR) methods in which a third party with no decision-making power often facilitates informal talks and listening to address conflicts between concerned parties for possible mutually beneficial solutions (Bush & Folger, 2005; Haynes, 1994; Irving & Benjamin, 1995). When used in helping couples in conflict to reconcile or to strengthen marriages, mediation takes the form of marriage mediation (Boardman, Fiske, Israel, & Neumann, 2009, May; Boardman, 2013). Also known as mediation to stay married, marriage mediation is an approach to helping couples at all stages of marital relationships such as newlywed couples, …

Appetite-Regulating Hormones In Energy Compensation With Exercise, Jack Moreland

Theses and Dissertations--Nutrition and Food Systems

Background: The appetite-regulating hormones may influence compensatory increases in energy intake with exercise, although this causal relationship has been difficult to prove in a longitudinal trial.

Methods: 37 participants (29 female) aged 18 to 40 years performed aerobic exercise 6 days (6d), 2 days (2d), or 0 days per week for 12-weeks. Concentrations of ghrelin, leptin, glucagon-like peptide 1 (GLP-1), and insulin were assessed before (fasting, minute 0) and after a standardized meal at minute 15, 30, 45, 60, 90, 120, 150, and 180. Linear mixed-effects models were used to model the relationships between time point (12 weeks vs. baseline) …

Cardiac Effects Of Obesity During Pregnancy In C57bl/6j Mice, Kayla Lynn Dudick

Theses and Dissertations--Nutrition and Food Systems

Objective: Pregnancy requires profound cardiac and metabolic adaptation. Left ventricular (LV) mass is increased in response to pregnancy, but is not associated with cardiac damage. In contrast, obesity-mediated cardiac hypertrophy is pathological. Data from animal studies indicate dietary fatty acid composition may have a protective effect during states of extreme cardiac physiological adaptation. In contrast, aberrant cardiac metabolism is a hallmark of disease. Over a third of reproductive-age women in the United States are obese, but there is a paucity of data describing the effect of obesity on maternal cardiac adaptation to pregnancy. The objective of this study was to …

Automated Testing And Bug Reproduction Of Android Apps, Yu Zhao

Theses and Dissertations--Computer Science

The large demand of mobile devices creates significant concerns about the quality of mobile applications (apps). The corresponding increase in app complexity has made app testing and maintenance activities more challenging. During app development phase, developers need to test the app in order to guarantee its quality before releasing it to the market. During the deployment phase, developers heavily rely on bug reports to reproduce failures reported by users. Because of the rapid releasing cycle of apps and limited human resources, it is difficult for developers to manually construct test cases for testing the apps or diagnose failures from a …

The Affordable Care Act And Medication-Assisted Treatment Accessibility: A Context-Inclusive Review Of Research, Jacob Blevins

MPA/MPP/MPFM Capstone Projects

This paper provides a contextual review of research investigating associations between the health insurance reforms implemented by the Affordable Care Act and the accessibility and utilization of medication-assisted treatment for opioid use disorder. Research indicates that relative to 2008, the year of initial Medicaid expansions in 2014 is nationally associated with increased rates of insurance coverage, increased rates of treatment, and reduced rates of individuals with opioid use disorder forgoing treatment due to financial concerns (McKenna 2017). Between the year prior to state Medicaid expansion and the third year after it, the number of specialty treatment admissions related to the …

Effective Elective? Elective Courses’ Impact On Student Performance During Associated Advanced Pharmacy Practice Experiences, Shelby Spencer Tungate

MPA/MPP/MPFM Capstone Projects

Experiential education programs at colleges of pharmacy are guided by standards set forth by the Accreditation Council for Pharmacy Education (ACPE.) Exactly how these standards are met, however, is often determined by the individual college of pharmacy. This includes deciding how students are selected and placed on their fourth-year rotations, referred to as Advanced Pharmacy Practices Experiences, or “APPEs.” While it may seem that students who have taken elective courses focused on specialized topics, such as pediatrics or geriatrics, will perform better on related APPEs, this thought remains largely unfounded. Using four years of student data at the University of …

Evaluating The Labor Supply And Migration Effects Of The Interstate Medical Licensure Compact, William Clay Fannin

MPA/MPP/MPFM Capstone Projects

A growing body of literature suggests that occupational licensing distorts economic behavior through various mechanisms, such as inflating prices and inhibiting interstate mobility. To combat some of these ill-effects, policymakers have turned to interstate compacts as a way to promote uniformity in licensing requirements across states and facilitate license portability. Despite the development of interstate compacts for numerous licensed occupations and professions, evidence of their efficacy in the literature is thin. Based on data from over 70,000 physicians from 2012 to 2018, I construct a difference-in-differences model to estimate the effects of the adoption of the Interstate Medical Licensure Compact …

Congressional Appropriations And Earmarks An Analysis Of The Economic And Political Effects, Paul Anthony Allen

MPA/MPP/MPFM Capstone Projects

The effects of political characteristics on the Congressional appropriations process have remained a subject of debate in recent years. Congressionally directed spending influenced by these effects are defined as earmarks. To counter the practice of earmarking, Congress implemented multiple reforms and rules to curb the influence of partisan agendas. Total federal appropriations by year and state from 2002 – 2018 were aggregated to test the significance of the economic and political effects. This model utilized a time series fixed effects regression to determine the results that suggest select political characteristics of U.S. Senators remained significant in the distribution of federal …

Impact Of Vaccine Availability On The Number Of Children Vaccinated And Under-Five Mortality In Tanzania, Katelyn Batliner

MPA/MPP/MPFM Capstone Projects

Stockouts have previously been reported to interrupt immunization services in low-and-middle income countries. However, there has been little research to understand the direct impact of stockouts on the number of children immunized and no research to understand the impact on under-five mortality. Using panel data from Tanzania’s Vaccine Information Management System training program, a regression model with fixed and random effects is used to analyze the effect of stockouts on the number of children immunized. The Lives Saved Tool® is used to estimate the effect of stockouts on under-five mortality. The results suggest that stockouts have a statistically significant impact …

Organic Farming And Incidence Rates Of Select Health Outcomes: An Evaluation Of The Usda Certified Organic Program, Aja Croteau

MPA/MPP/MPFM Capstone Projects

Medical studies over the past few decades have shown increasing evidence that exposure to pesticides is associated with numerous health conditions, specifically Non-Hodgkin Lymphoma, leukemia, asthma, and depression. Pesticides are widely used across the United States to ensure an affordable and bountiful food supply, but many of the chemicals used pose notable health risks. Numerous programs exist to measure and monitor pesticide exposure from agriculture, but researchers and public health experts remain uncertain of the efficacy of regulatory programs on reducing the amount of pesticide used and on protecting citizens from exposure. Organic agriculture, which uses significantly fewer pesticides than …
