WOMEN RETURNING TO THEIR FAMILIES AND COMMUNITIES AFTER INCARCERATION

Julius Johnson
The voices of women in re-entry from prison have been muted for many decades. Prior research conducted on men and prison re-entry has been used to shape not only prisons but also the reentry process for women. It is because of this oversight that the gender-specific needs of women in the justice system have gone unnoticed. Once released, formerly incarcerated women face the almost impossible task of finding employment. Many women who find employment have...

USE OF SURVEY DATA TO GUIDE THE DEVELOPMENT OF BEST PRACTICES FOR INSTRUCTION FOR THE RECRUITMENT OF VOLUNTEER FIREFIGHTERS

Jeffrey Kimble
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....

DEVELOPING ALTERNATIVE PRACTICES FOR MANAGEMENT OF FLEA BEETLES ATTACKING EGGPLANT AND LEAFY BRASSICACEOUS GREENS

Robert Brockman
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...

Multi-Modal Medical Imaging Analysis with Modern Neural Networks

Gongbo Liang
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...

Effect o Temporal Instability of Factors Contributing to Single-Vehicle Crash Severity--a Mixed Logit Approach

A M Hasibul Islam
This study investigates the factors associated with single-vehicle crash injury severity using five years (2014 – 2018) of crash data from Kentucky, USA, using a mixed (random-parameter) logit model. We also explore the temporal heterogeneity of the correlated factors across different times of the day. Most crash-severity models assume that the estimated parameters remain temporally stable. For instance, the effect of light conditions on crash severity may differ based on the time of the crash...

Nonparametric Tests of Lack of Fit for Multivariate Data

Yan Xu
A common problem in regression analysis (linear or nonlinear) is assessing the lack-of-fit. Existing methods make parametric or semi-parametric assumptions to model the conditional mean or covariance matrices. In this dissertation, we propose fully nonparametric methods that make only additive error assumptions. Our nonparametric approach relies on ideas from nonparametric smoothing to reduce the test of association (lack-of-fit) problem into a nonparametric multivariate analysis of variance. A major problem that arises in this approach is...

RESPONSES TO SYMPTOMS AMONG PATIENTS WITH HEART FAILURE

Chin-Yen Lin
Patients with heart failure (HF) suffer from chronic and progressive symptoms. Failure to respond appropriately to escalating symptoms of HF causes a delay in seeking care, which results in worse symptom status, frequent rehospitalizations, and contributes to higher mortality. In order to enhance HF self-care, promote timely care-seeking, and improve outcomes, identification of factors that affect patients’ responses to symptoms and their decisions to seek care is essential. Thus, the purposes of this dissertation were...

Relevant Angry Affect Slows Response Time To Commands

Aleah Combs
Previous research has found that emotional prosody can interact with speech perception and listeners’ processing of the meaning of particular word/emotion pairings(Kim and Sumner, 2017). What remains unclear is how this interactive processing can affect behavioral responses such as responses to imperatives. To answer this question,71 participants were presented with a series of commands given in a relevant affect.Commands were read either with angry prosody, happy prosody, or neutral prosody (control) and the participants were...

National Guard Members with Suicide Ideation

Amy Brown
Background. Veterans are overrepresented among suicide deaths in the United States, representing 20% of annual suicide deaths but only about 1% of the U.S. population (Department of Veteran Affairs, 2010). Of all military suicide deaths in 2016, one-third (33.4%) were in the National Guard or Reserves (Department of Defense, 2018). Previous suicidal ideation or behavior (SIB) has been shown to increase risk of subsequent ideation or behavior in both active duty and veteran samples (Bryan,...

ELUCIDATING MOLECULAR FUNCTION OF MITHRAMYCIN AND ANALOGUES FOR THE TREATMENT OF EWS-ETS EXPRESSING CANCERS

Reiya Hayden
Introduction: Chromosomal translocations are common in cancer. In many cancers such as prostate cancer, leukemia and Ewing sarcoma, chromosomal translocations are the main driver of malignancy. Ewing sarcoma is a cancer diagnosed mostly in children and adolescents that has very grim outcomes for patients with metastasis and recurrent disease. Malignancy in Ewing sarcoma is due to EWS-FLI1, an aberrant transcription factor that is the result of a chromosomal translocation. EWS-FLI1 is the main driver of...

IDENTIFICATION OF ADSORBATE FT-IR BANDS USING IN-SITU TECHNIQUES

Robert Pace
To meet increasingly stringent automotive emissions standards, further improvements in catalytic converter design are necessary. Current automotive catalyst systems are effective at eliminating emission of nitrogen oxides (NOx) once the catalyst reaches operational temperature (~200 °C). NOx emitted at lower catalyst temperatures now comprises most of the NOx released during a typical test cycle. Referred to as “the cold start problem” this issue has come to the forefront of automotive catalyst development, as mitigating these...

TESTING INTERPRETATIONS OF THE DISPLACEMENT MAGNITUDE OF THE TETON FAULT AND UPLIFT OF THE TETON RANGE, WYOMING WITH INTEGRATED FLEXURAL-KINEMATIC AND THERMAL MODELING

Autumn Helfrich
The Teton fault is a range-front normal fault in northwestern Wyoming. Previous estimates of the maximum displacement (Dmax) on the Teton fault cover a wide range (2 - 11 km). Discrepancies also exist regarding the slip onset timing, which spans 2 - 13 Ma. To address these discrepancies, the exhumation history of the Teton Range is here investigated using forward flexural-kinematic (Move) and thermal-kinematic (Pecube) models that can be compared with previously reported apatite fission...

In the Shadows of Apollo

Stuart Simms
In the Piney Woods of Mississippi, John C. Stennis used political connections to displace small communities in a 150,000-acre space in Hancock County, Mississippi for the creation of a rocket test facility for NASA. What became the John C. Stennis Space Center created a narrative that preached of the benefits of the facility in the region while local residents from the displaced communities remember the facility in different terms.

STRESS AND CANCER TREATMENT

Emily Marie Johnson
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...

Eigenvalue Statistics and Localization for Random Band Matrices with Fixed Width and Wegner Orbital Model

Benjamin Brodie
We discuss two models from the study of disordered quantum systems. The first is the Random Band Matrix with a fixed band width and Gaussian or more general disorder. The second is the Wegner $n$-orbital model. We establish that the point process constructed from the eigenvalues of finite size matrices converge to a Poisson Point Process in the limit as the matrix size goes to infinity. The proof is based on the method of Minami...

Potential Effect of Cable Median Barriers on Commercial Vehicle Crossover Crashes

Nikiforos Stamatiadis, Shraddha Sagar, Samantha Wright, Eric R. Green, Reginald R. Souleyrette, Michael A. Fields & Teng Alex Wang
In 2016, commercial motor vehicles (CMVs) were involved in 4,079 fatal crashes in the U.S., representing 11.8 percent of all fatal crashes. State of Kentucky crash data for 2015-2016 show that per capita crash rates and increases in crash-related fatalities exceeded the national average. Crossover crashes occur when a vehicle leaves its intended path and veers into the path of oncoming traffic, typically resulting in head-on or sideswipe opposite direction crashes. Cable median barriers are...

CAPILLARY FLOW OF LIQUID ALUMINUM ALLOY IN WETTING AND WETTING/NON-WETTING SYSTEMS

Yangyang Wu
In this dissertation, the capillary flow of liquid aluminum alloy in both wetting and wetting/non-wetting systems is investigated. The impact of gravity and surface topography on the capillary flow has been studied in a wetting/non-wetting assembly (an AA3003/Al2O3 wedge-tee configuration). The research includes (i) kinetics of liquid Al-Si-KxAlyFz alloy triple line movements and dynamic macro advancing and receding contact angles and (ii) free surface profiles of the molten alloy driven by surface tension and impacted...

GRAPHENE IN A UNIFORM MAGNETIC FIELD

Ankur Das
We study monolayer graphene in a uniform magnetic field in the absence and presence of interactions. In the non-interacting limit, for p/q flux quanta per unit cell (p, q are coprime integer), the central two bands have 2q Dirac points in the Brillouin zone (BZ) in the nearest-neighbor model. These touchings and their locations are guaranteed by chiral symmetry and the lattice symmetries of the honeycomb structure. If we add a staggered potential and a...

ASSOCIATIONS BETWEEN PSYCHOSOCIAL STRESSORS, GENES, AND CARDIOVASCULAR DISEASE IN AT-RISK ADULTS

Kaitlin Key
Psychosocial stressors have a significant adverse impact on cardiovascular health. While better medical treatments and increased emphasis on healthy lifestyle have improved cardiovascular health for many in the United States over the past 50 years, there are persistent inequities in cardiovascular disease (CVD) rates, with the highest rates among populations burdened by chronic exposure to psychosocial stressors such as discrimination and anxiety, among others. Genetic factors may interact with these stressors further influencing the rates...

The four-part process of research...

INSIDE OUTSIDE

Nathan Miller
By the turn of the twentieth century, the sight and sound of a little brass band of uniformed evangelists on street corners declaring war on sin became ubiquitous in American cities. Although Salvationists came to hold a cherished place in society, Americans greeted their initial invasion with contempt. They came with a message of transformative redemption for the poor and disenfranchised, loudly declaring that anyone and anything could be made holy and fit for God’s...

SHINY OBJECTS, HIDING PLACES

Emily Barrett
As local governments increasingly turn to data-driven solutions to help address some of their most acute challenges, from entrenched poverty to affordable housing, they often call on community-engaged researchers as collaborators, analysts and experts. While critical scholarship has highlighted the problematic logics underpinning this turn to data and digital technologies as the solution for urban issues, university-community partnerships offer a unique opportunity to further explore not only how these discourses materialize, but also how they...
