An Evaluation of How Repealing West Virginia’s Prevailing Wage Law Affected the Cost of Public Construction

Michael W. Clark & Kenneth Tester
This study compared school construction costs before and after legislative changes to prevailing wage laws in West Virginia. The study uses data provided by the School Building Authority of West Virginia (SBA). The data suggests that school construction costs increased in the years prior to the legislative changes and decreased after. Comparing projects bid with and without prevailing wages since 2013 suggests construction costs per square foot decreased by 7.3 percent since the removal of...

The Forestry Reclamation Approach

William E. Bond
The spread of surface coal mining has resulted in loss of forests in the Appalachian region. The Forestry Reclamation Approach (FRA) was developed to provide guidance for restoring forests on reclaimed mined land. This study hypothesizes that the FRA will result in larger magnitude of sediment accumulation rates in reclaimed mine sites compared to those reclaimed using grassland reclamation. Three sediment cores and six trenches were sampled within four reclaimed mined and three previously logged...

Integrating Cover Crops and Herbicides for Horseweed [Conyza canadensis (L.) Cronq.] Management Prior to Soybean [Glycine max (L.) Merr.]

Austin Sherman
Horseweed (Conyza canadensis (L.) Cronq.) is prevalent in Kentucky and can be difficult to control. Research has shown multiple weed control methods to be more sustainable than relying on chemical control alone, so the use of multiple methods for horseweed management was examined in this study. The main objective was to determine best practice(s) to reduce horseweed prior to soybean [Glycine max (L.) Merr.]. Treatments included: fall-planted cover crop [CC; cereal rye (Secale cereale L.)...

Redefining Construction As-Built Plans to Meet Current Kentucky Transportation Cabinet Needs

Victoria Lynn Lasley, Steven Waddle, Tim Taylor & Roy E., Jr. Sturgill
As-built plans have traditionally been used by construction industry practitioners to record changes made during construction. As-builts provide valuable information for new design projects as well as rehabilitation and remediation projects. The completeness and accuracy of these plans are essential for transportation industries and their success. While the importance of as-builts is widely recognized, preparing them can be difficult and time-consuming; many entities — especially public agencies — lack the resources necessary to produce accurate...

A Compromised Liver Alters PCB Toxicity and Nutrient Metabolism

Jazmyne D. L. Barney
Environmental contamination is a public health concern. In particular persistent organic pollutants like Polychlorinated Biphenyls (PCBs) have been associated with multiple chronic inflammatory diseases, including non-alcoholic fatty liver disease (NAFLD). NAFLD prevalence has steadily increased and is expected to continue to rise with an estimated 25% of the world’s population and 80-100 million people affected in the United States alone. Importantly, the liver is the primary site for endobiotic and xenobiotic metabolism, hence its proper...

Implementation and Analysis of True Lean in a Startup Company by Using PCDA Model, a Case Study in a Manufacturing Venture

Ankit Jangid
The purpose of this research is to implement and analyze the true lean transformation in a manufacturing start-up organization. Often, lean transformations are observed in developed manufacturing organizations having sophisticated production lines and numerous employees, where lean tools are utilized to reduce waste while increasing profit. However, this type of transformation is narrowly focused on quantifiable process results and falls short of the ultimate goal, establishing a true lean culture within the organization. As a...

Kentucky Transportation Center (KTC) researchers looked at IC data collected from these projects — resulting in the production of eight analyzable data sets — to determine whether they complied with the special construction note included in contract documents. The report also compares the intelligent compaction measurement value (ICMV) collected...

Wage Disparity in the Accounting Profession and Information Quality

Russell Williamson
Does wage disparity, measured as the difference between highest and lowest paid workers, affect the quality of reported financial information? I collect accounting professional wage data from an international accounting and finance employment placement firm for the period of 1972 to 2017. I investigate to what degree wage disparity in corporate and public accounting has affected accounting information quality by testing predictions derived from equity theory and tournament theory. I find that vertical wage disparity...

Spatial Augmented Reality Using Structured Light Illumination

Ying Yu
Spatial augmented reality is a particular kind of augmented reality technique that uses projector to blend the real objects with virtual contents. Coincidentally, as a means of 3D shape measurement, structured light illumination makes use of projector as part of its system as well. It uses the projector to generate important clues to establish the correspondence between the 2D image coordinate system and the 3D world coordinate system. So it is appealing to build a...

Modeling Daily Posttraumatic Stress Symptoms and Mental Contamination Experiences Among Survivors of Sexual Trauma

Alex Brake
Mental contamination (i.e., feelings of dirtiness in the absence of contact with a contaminant) is a potentially important yet understudied factor in posttraumatic psychopathology, particularly for survivors of sexual trauma. Mental contamination has been linked to PTSD symptom severity, negative affect, and coping cross-sectionally and in lab-based paradigms, but research has yet to assess these relationships in ecological contexts. The present study extends previous cross-sectional findings by modelling relationships between mental contamination and posttraumatic psychopathology,...

Study of Cell Charging Effects for the Neutron Electric Dipole Moment Experiment at Oak Ridge National Laboratory

Mark Broering
The neutron electric dipole moment (nEDM) collaboration at the Spallation Neutron Source plans to use ultra-cold neutrons in superfluid helium to improve the nEDM limit by about two orders of magnitude. In this apparatus, neutrons are stored in poly(methyl methacrylate), PMMA, cells located in a strong, stable electric field. This electric field is produced by high voltage electrodes located outside of the neutron cells. Several sources generate charged particles inside the neutron cells. The electric...

Intentional Personality Change

Elizabeth N. Riley
Personality stability across the lifespan has been well documented, but within that overall stability there is also evidence of meaningful change. There is both theoretical and empirical evidence to suggest that personality change can occur at the volition of the individual, through behavioral processes. The current study tested whether an emotion modulation intervention that promoted behavior change could be applied to reduce a related, high-risk personality trait (negative urgency) and a high-risk behavior (heavy alcohol...

Stretching the Dollar

Rachael Deel
In the climate of prioritizing retention and pressure to move an increasingly diverse undergraduate population towards degree, it is critical that educational research consider the multiple, overlapping identities of students and how that influences their experiences on campus. The number of low-income students entering four-year institutions is growing each year, including at the University of Kentucky. This study aims to extend our understanding of social class beyond the material and focus on the affective dimensions...

Emotional Closeness within Romantic Relationships

McKenna Fey
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...


Christopher Asbery
Transmission lines are designed to transport large amounts of electrical power from the point of generation to the point of consumption. Since transmission lines are built to span over long distances, they are frequently exposed to many different situations that can cause abnormal conditions known as electrical faults. Electrical faults, when isolated, can cripple the transmission system as power flows are directed around these faults therefore leading to other numerous potential issues such as thermal...

Focused electron beam induced processing (FEBIP) is a nano-scale fabrication technique that allows the direct deposition of functional materials. However, it suffers from significant drawbacks, such as high cost, low speed, unavailable precursors for many materials and low purity of deposits. Liquid-phase focused electron beam induced processes (LP-FEBIP) are being investigated due to the potential benefits over the gas phase technique. In this method, deposition or etching occurs at the interface between a substrate and...


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...
