The North American Transportation Security Center

Steven Douglas Kreis & Michael M. Barclay
Executive Summary There are over 800,000 hazardous materials (hazmat) shipments over the nation’s roads each day. According to the U.S. Department of Homeland Security (DHS), terrorist activity related to the transportation of hazardous materials represents a significant threat to public safety and the nation’s critical infrastructure. Specifically, the federal government has identified the government’s inability to track hazmat shipments on a real-time basis as a significant security vulnerability. In 2004, the U.S. Federal Motor Carrier...

Evaluation of Guardrail Needs and Update of Guardrail Rating Program

Brian K. Howell, William Nicholas Staats & Nancy Albright
The Kentucky Transportation Cabinet (KYTC) seeks to reduce the frequency of roadway departure crashes, which often prove fatal. Roadside barriers such as guardrail have proven effective at mitigating these crashes, however, the demand for installations is high throughout the state. KYTC must prioritize prospective guardrail locations to match available funds with the most critical, or unsafe, sites. The current guardrail rating program (GRP) was established in 1989 to identify and prioritize guardrail needs. Despite periodic...

Dust Transportation and Settling within the Mine Ventilation Network

Anand Kumar
Dust is ubiquitous in underground mine activities. Continuous inhalation of dust could lead to irreversible occupational diseases. Dust particles of size lower than 75.0 µm, also known as float coal dust, can trigger a coal dust explosion following a methane ignition. Ventilation air carries the float coal dust from the point of production to some distance before it’s deposited on the surfaces of underground coal mine. Sources of dust are widely studied, but study of...

Learning to Map the Visual and Auditory World

Tawfiq Salem
The appearance of the world varies dramatically not only from place to place but also from hour to hour and month to month. Billions of images that capture this complex relationship are uploaded to social-media websites every day and often are associated with precise time and location metadata. This rich source of data can be beneficial to improve our understanding of the globe. In this work, we propose a general framework that uses these publicly...

Analysis of Push-Up and Pull-Up Variants to Develop an Upper Extremity Model

Push-Ups and Pull-Ups are effective dynamic exercises that mimic high level function activities, such as those used in the military. The model developed allows for researchers to analyze the forces and moments associated with the shoulder, elbow and wrist, to further assess function in military personnel, athletes and the active population. The model also follows the guidelines set forth by the...

Limón Patwa

Robert Bell
The primary purpose for this research is to examine and identify the social functions of Limón Patwa, a closely related language to Jamaican Patwa spoken by the Afro-Caribbean community of Costa Rica. There is a unique relationship regarding the language contact between Spanish and LP, where the maintenance of this English based language can certainly be complicated by a Spanish language dominant environment. Studying the historical migration of this Afro-Caribbean population to Costa Rica in...

Kentucky School Districts as Educational Bright Spots

Michael T. Childress
Every year a select group of Kentucky school districts perform better than expected on measures of educational achievement. These measures include things like the percentage of elementary students who achieve proficiency or distinguished in reading, or the proportion of less‐advantaged middle school students who show a similar level of competency on the math assessment. There are wide differences in the learning environments, finances, and student outcomes among and within Kentucky’s 173 school districts. This is...

Modulation of Inflammatory Cytokine, Chemokine, and Toll-Like Genes and Transcriptome Analysis of Equine Endothelial Cells Following Infection with Equid Herpesvirus-1, and Equine Arteritis Virus.

Saranajith Wangisa Dunuwille
EHV-1 is a double-stranded DNA virus whereas EAV is a positive sense, single-stranded RNA virus. Therefore, genetically, they are very different from one another. However, both these viruses are endotheliotropic and thus, infect and replicates in equine endothelial cells resulting in vasculitis. Vasculitis is central to the pathogenesis of these two viruses. Thus, the main objective of this thesis was to investigate the inflammatory and innate immune responses of EECs that contribute towards the development...

Semisynthetic Aurones

Yanqi Xie
Aurones belong to an uncommon class of plant flavonoids that provide the bright yellow coloration of some ornamental flowers and that possess a range of biological activities. Structure-activity relationships (SAR) in the aurone pharmacophore identified heterocyclic variants of the (Z)-2-benzylidene-6-hydroxybenzofuran-3(2H)-one scaffold that possessed low nanomolar in vitro potency in cell proliferation assays using various cancer cell lines, in vivo potency in prostate cancer PC-3 xenograft and zebrafish models, selectivity for the colchicine-binding site on tubulin,...


Yuanyuan Wu
The rapidly growing volume of electrophysiological signals has been generated for clinical research in neurological disorders. European Data Format (EDF) is a standard format for storing electrophysiological signals. However, the bottleneck of existing signal analysis tools for handling large-scale datasets is the sequential way of loading large EDF files before performing an analysis. To overcome this, we develop Hadoop-EDF, a distributed signal processing tool to load EDF data in a parallel manner using Hadoop MapReduce....

A Comparison of Appalachian and Non-Appalachian Kentucky DUI Offenders

Megan F. Dickson, Megan Kissel & J. Matthew Webster
Background: Driving under the influence has been an overlooked consequence of the opioid epidemic. Although recent reports have highlighted the increased prevalence of DUI in rural communities and the extensive mental health problems and criminal and drug use histories among rural Appalachian DUI offenders, it is unclear how Appalachian DUI populations compare to DUI offenders in other regions. Purpose: To help fill this void in the literature, the current study uses a statewide sample to...

Psychometric properties of a scale designed to measure knowledge of ASD were also explored. Data from 620...

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...

Factors Influencing Music Therapy Career Choice in the United States

Margaret R. Scheppmann
The understanding of why students decide to become music therapists is valuable information for music therapy educators and policy makers and published information is lacking. The use of expectancy-value theory provides a framework to understand student choices. Researchers can better understand why students purse a career in music therapy by examining students’ abilities, beliefs, expectancies, and values related to the choice. The purpose of this study was to examine why current undergraduate and equivalency students...

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...

Shifting Personas

Lela Lyon
This thesis analyzes how Taylor Swift has changed the way she expresses her Southern identity, specifically her dialectal features, over the course of her career and through her switch from country music to pop music. There were two processes to assess the change in Swift’s speech: the production of /ai/ tokens in interviewed speech and the perception of dialectal change by fans in the comment sections of the interviews on YouTube. Seven interviews on YouTube...

Investigation of Atmospheric Effects on Vapor Intrusion Processes Using Modelling Approaches

Elham Shirazi
Most people in the United States (US) spend considerable amount of time indoors—about 90% of their time as compared to outdoors, which makes the US population vulnerable to adverse health effects of indoor air contaminants. Volatile organic compound (VOC) concentrations are well-known to be higher in indoor air than outdoor air. One source of VOC concentrations in indoor air that has gained considerable attention in public health and environmental regulatory communities is vapor intrusion. Vapor...

Impact pf Conformational Change, Solvation Environment, and Post-Translational Modification on Desulfurization Enzyme 2'Hydroxybiphenyl-2-Sulfinate Desulfinase (DSZB) Stability and Activity

Landon C. Mills
Naturally occurring enzymatic pathways enable highly specific, rapid thiophenic sulfur cleavage occurring at ambient temperature and pressure, which may be harnessed for the desulfurization of petroleum-based fuel. One pathway found in bacteria is a four-step catabolic pathway (the 4S pathway) converting dibenzothiophene (DBT), a common crude oil contaminant, into 2-hydroxybiphenyl (HBP) without disrupting the carbon-carbon bonds. 2’-Hydroxybiphenyl-2-sulfinate desulfinase (DszB), the rate-limiting enzyme in the enzyme cascade, is capable of selectively cleaving carbon-sulfur bonds. Accordingly, understanding...

Caregivers' Influence on Patients' Heart Failure Self-Care, Hospital Readmission and Mortality

Linda Clements
Background: Heart failure (HF) is a leading cause of hospitalization, readmissions, and death in the United States. Patients hospitalized for HF are at risk for readmission, in- hospital mortality, and early post-discharge death. In the United States, inpatient care has been estimated to cost $83,980 over the lifetime of each patient with HF. The majority of patients with HF depend on caregiver support for successful HF self-care, which is essential for optimal patient outcomes. Support...

Encuentro Con la Precariedad

María Julia de León Hernández
In 2008, Spain’s financial crisis had a great impact on the primary sector on which the nation’s ‘economic miracle’ was founded: housing.Land speculation, the increase in housing construction, and easy loans had become one of the hallmarks of twenty-first-century Spanish identity. The crisis del ladrillo (“brick crisis”) plunged the national economy into chaos and condemned many Spanish citizens to job insecurity, loss of earning power, threat of eviction, and put them at high risk of...

Partita for 8 Voices & Wind Ensemble

Kaitlin Bove
Partita for 8 Voices (2012) is a groundbreaking a cappella work that earned its composer, Caroline Shaw, the record of youngest recipient of the Pulitzer Prize for Music in 2013. While the work continues to receive performances from its premiere ensemble, Roomful of Teeth, no transcription of the piece to any other ensemble type existed at the beginning of this DMA project. The author sought to transcribe a piece by a living female composer with...

Policy, Aggregate Productivity and Misallocation

Guowen Chen
This dissertation explores the effects of factors such as industrial policy and listing on the stock market on manufacturing firms’ profitability and productivity. The second chapter investigates the effect of industrial policies on misallocation using a rich data-set of Chinese firms. Using a difference-in-difference approach, I provide evidence that government policies (i.e. the 10th Five Year Plan) favoring particular industries lead to increased misallocation (i.e., an increase in the dispersion of revenue productivity across firms...

Learning to Write in an Academic Genre

Lyudmyla Ivanyuk
In this multiple case study, I examined what types of sociocultural resources adult English learners brought with them from their previous contexts and what new resources they drew upon in the U.S. while learning to write in the essay genre. The study also identified how the participants chose to use previous and new sociocultural resources as mediated by the essay genre in the U.S. The following research foci shaped this study: (1) What types of...

Evaluation of Current and Emerging Techniques for Measuring Eggshell Integrity of the Domestic Fowl

Lauren Wood Nolan
This dissertation is an investigation into the effect of different zinc sources and levels on eggshell quality and microstructure, as well as keel bone damage. Eggshell function is two-fold; eggshells function to protect the developing embryo, as well as act as a barrier against bacterial penetration, optimizing food safety of the egg for human consumption (Mabe et. Al., 2003). Two small trials were conducted in order to determine differences in eggshell microstructure of eggs produced...
