Traffic Incident Management Dashboard

Xu Zhang, Reginald R. Souleyrette, Alex Wang, Paul Ross, Eric R. Green & Mei Chen
Traffic incidents remain all-too-common events on Kentucky’s roadways. They negatively impact the safety of the traveling public and emergency responders and cause significant traffic delays. Congestion associated with incidents can instigate secondary crashes, exacerbating safety risks and economic costs. Traffic incident management (TIM) provides an effective approach for managing highway incidents and reducing their occurrence and impacts. This report discusses the establishment of and methods of calculation for five TIM performance measures that can be...

Proteomic Analysis of Human Sural Nerve

Craig van Horne , Monica Chau & Jorge Quintero
A proteomic analysis, using mass spectrometry and immunoassays, of the human peripheral nervous system's response to a transection injury. We obtained, from the same participants, the protein levels in freshly cut and degenerating human sural nerve tissue.

Best Practices for Performance Measurement in Transportation Operations and Maintenance

Bryan Gibson, Rachel Catchings, Chris Van Dyke, Steve Waddle & Doug Kreis
Public agencies benefit from measuring their performance as it helps to focus employee and organizational activities. State departments of transportation have become more performance-oriented over the past two decades and routinely collect data on highway safety, infrastructure condition, system operations, project delivery, winter maintenance, transit, bicycle and pedestrian facilities, and customer service. While the Kentucky Transportation Cabinet (KYTC) use performance measures in a variety of areas, the agency wants to adopt new metrics related to...

THE EFFECTS OF USING CONSTANT TIME DELAY TO TEACH DIGRAPHS TO ELEMENTARY STUDENTS WITH MILD DISABILITIES

Sara Schuer
Constant time delay (CTD) is a near-errorless response prompting procedure that involves a presentation of a stimulus, a delay interval, and a controlling prompt. The purpose of this study was to determine the effectiveness of teaching vowel/consonant digraph sounds to children with mild disabilities using constant time delay. A multiple probe (conditions) across behaviors design, replicated with three students, was used. The results indicated that CTD is effective in teaching vowel/consonant digraphs to elementary students...

Research on Power System State Estimation Problems – Series-Compensated Transmission Line Parameter and Load Model Parameter Estimation

Yiqi Zhang
Transmission line and load model parameters are essential inputs to power system modeling and simulation, control, protection, operation, optimization, and planning. These parameters usually vary over time or under different operating conditions. Thus, reliable estimation methods are desired to ensure the accuracy of those parameters. This research focuses on estimation for transmission line parameters and the ZIP load model. The proposed estimation methods can use both online measurements and historical data of a specified duration....

THE EFFICACY OF ACCELERATING UNDERPREPARED COMMUNITY COLLEGE STUDENTS USING A COREQUISITE LIBERAL ARTS MATHEMATICS COURSE

Drew Wilkerson
Every year, millions of first-time students enroll in community colleges underprepared for college-level work in mathematics. Typically, these students are referred to a sequence of developmental courses designed to remediate their skills and prepare them for college-level work. Recently, educators and policy makers have questioned the efficacy of these courses, especially since most students assigned to remedial courses never complete the sequence and enroll in college-level courses. Calls to reform developmental mathematics have included changes...

Landslide Soil Hydrology Data for Three Landslides in Kentucky

Matt Crawford & Lindsey Bryson
This data is from three landslides monitored in Kentucky between October 2015 and September 2020. The purpose was to capture and analyze subsurface hydrologic conditions within the landslides at different slope positions over time. The site descriptions, field methodology, data-acquisition techniques, and observations provide a general picture of soil moisture in hillslope soils. Data collected includes volumetric water content, soil water potential, bulk electrical conductivity, bulk dielectric permittivity, temperature. Water potential is the energy state...

Fluid Dynamics

James Evans
Water has remained a subject of all kinds of musical works since at least the middle ages. These musical works lack the concrete representational capacity of paintings, photographs, and films, relying instead on more abstract metaphorical constructs to convey water imagery. Current scholarship on water music typically centers on Romantic and Impressionist works and does not examine the process of signification by which musical signs portray water. The principal goal of this study is to...

2020 Kentucky Transportation Cabinet Maintenance Customer Survey

Bryan Gibson, Katherine Connair, Chris Van Dyke, Clark Graves & Doug Kreis
The Kentucky Transportation Cabinet (KYTC) periodically surveys drivers to understand their perceptions of the agency’s maintenance activities. In 2020, Quadratics in conjunction with the Kentucky Transportation Center surveyed 2,400 licensed drivers throughout the state to gauge their perceptions of highway maintenance, identify areas of strength and weakness, and discern how drivers obtain information on traffic and weather conditions. Survey participants answered questions about five areas of highway maintenance — roadside features, pavement surfaces, shoulders, drainage,...

THE ROLES OF THE ACTIN NETWORK AND CO-OPTED HOST FACTORS IN TBSV REPLICATION

Melissa Molho
Positive-stranded (+) RNA viruses are the largest family of viruses that infect plants, causing important economic losses in different crops. Tomato bushy stunt virus (TBSV), a small positive-stranded RNA virus, has emerged as a model virus to study virus-host interactions. TBSV encodes for only five proteins, therefore, to infect the host cell TBSV co-opts selected host components and subverts specific molecular pathways. Firstly, I performed a proteomic screening using Arabidopsis proteins. I found that TBSV...

ARABINOXYLAN STRUCTURAL PROFILING OF COOL-SEASON PASTURE GRASSES VIA HIGH-PERFORMANCE ANION-EXCHANGE CHROMATOGRAPHY WITH PULSED AMPEROMETRIC DETECTION (HPAEC-PAD) ANALYSIS OF ENDOXYLANASE DIGESTS

Glenna Erin Joyce
Arabinoxylan (AX) is a major structural polysaccharide found in the cell walls of monocots such as cereal grains and pasture grasses. The variety of AX structural components and substitution patterns contribute to AX structural diversity between different monocot species as well as plant tissues. The rumen is the first digestion site of masticated food material in cattle and provides 70% of energy to host through fermentation of forage. There are many species of pasture grasses...

“IT’S THE ONLY THING WE HAVE”

Richard Carter
Women who secretly warn one another via informal communications about men in their environment who may engage in some kind of misconduct are participating in a whisper network. This dissertation employs the narrative paradigm to understand how these networks function in the context of professional actors. Interviews conducted with actors who have worked in a variety of communities were analyzed in order to better understand how whisper networks function as warning systems that must be...

DEVELOPMENT AND CLINICAL VALIDATION OF KNOWLEDGE-BASED PLANNING MODELS FOR STEREOTACTIC BODY RADIOTHERAPY OF EARLY-STAGE NON-SMALL-CELL LUNG CANCER PATIENTS

Justin Visak
Lung stereotactic body radiotherapy (SBRT) is a viable alternative to surgical intervention for the treatment of early-stage non-small-cell lung cancer (NSCLC) patients. This therapy achieves strong local control rates by delivering ultra-high, conformal radioablative doses in typically one to five fractions. Historically, lung SBRT plans are manually generated using 3D conformal radiation therapy, dynamic conformal arcs (DCA), intensity-modulated radiation therapy, and more recently via volumetric modulated arc therapy (VMAT) on a C-arm linear accelerator (linac)....

New Magnetic Field Models of the Moon

Dhananjay Ravat, Michael Purucker & Nils Olsen
We use L1-norm model regularization of |Br| component at the surface on magnetic monopoles bases and along-track magnetic field differences alone (without vector observations) to derive high quality global magnetic field models at the surface of the Moon. The practical advantages to this strategy are: monopoles are more stable at closer spacing in comparison to dipoles, improving spatial resolution; L1-norm model regularization leads to sparse models which may be appropriate for the Moon which has...

This report is one of the important ways that the Center for Business and Economic Research fulfills its mission to examine various aspects of the Kentucky economy. The analysis and data presented here cover a variety of topics that range from an economic forecast for Kentucky in 2020 to a broad presentation of factors affecting the economy.

Compositional Modeling

Students of composition develop two skills simultaneously: craft and creativity. Since students are more naturally inclined to focus on one of these skills over the other, finding the proper balance is an educational challenge. An effective pedagogical system for composition cultivates both of these necessary skills. Imitation was a preferred pedagogical approach during the Classical period. In his 1848 book School of Practical Composition, Carl Czerny instructs his readers to apply the extensive rules of...

PSYCHOSOCIAL PREDICTORS OF CHRONIC PAIN AND PAIN-RELATED DISABILITY 12 MONTHS AFTER LOWER EXTREMITY FRACTURE

Joshua Van Wyngaarden
Over 700,000 lower extremity fractures occur each year with a large portion of these patients developing adverse long-term pain and disability outcomes. Current literature indicates that 39% to 62.7% of all patients report continued pain long after traumatic lower extremity fracture. Concurrent physical limitations and reduced quality of life are common, with nearly one-third of all patients reporting pain-related disability seven years after limb threatening trauma, and approximately 50% of these patients having limitations in...

CLINICAL AND NEUROPHYSIOLOGICAL EFFECTS OF DRY NEEDLING ON INDIVIDUALS WITH CHRONIC ANKLE INSTABILITY

Jennifer Mullins
Ankle sprains are generally considered innocuous injuries; however, as many as 74% of patients will develop chronic symptoms. 1-3 Chronic ankle instability (CAI) is defined by a history of ankle sprain accompanied by ongoing bouts of giving way, residual ankle sprain symptoms, and a decrease in patient-perceived function. As understanding of sensorimotor deficits in individuals with CAI have advanced, treatment strategies have evolved to include a robust focus on balance training to mitigate dynamic and...

Wholeness and Belonging in Nikky Finney's Head Off & Split

Mary Rudolph
Nikky Finney’s Head Off & Split illuminates an urgent and radical eco-political project: the creation of whole, resilient, co-species communities capable of surviving interlocking political, social, and ecological crises. Finney foregrounds the strategic practice of belonging as a method of survival within contexts of systemic oppression and climate chaos. “Belonging,” in these terms, is not a “natural” ontological state, but a mode of co-being that is continually (re)created and (re)enacted through daily world-making practices: foodways,...

RESIDENTIAL RADON EXPOSURE, ITS CONTRIBUTION TO LUNG CANCER, AND SOCIAL DETERMINANTS OF RADON TESTING

Stacy Stanifer
Lung cancer is a highly preventable form of cancer. Cigarette smoking is the leading cause of lung cancer followed by radon gas exposure and exposure to secondhand smoke. Kentucky leads the nation in both incidence and mortality from lung cancer. Tobacco use in Kentucky continues to be a major public health concern as nearly one-quarter of adults report current tobacco use and just over one-third of Kentucky homes with children lack rules which prohibit smoking...

BIMETALLIC NANOPARTICLES INTEGRATED MEMBRANES FOR GROUNDWATER REMEDIATION

Hongyi Wan
The detoxification of chlorinated organics from groundwater, such as trichloroethylene (TCE), tetrachloroethylene (PCE), polychlorinated biphenyl (PCB) and carbon tetrachloride (CTC), is a challenging area. Reductive dechlorination has been investigated using iron and iron-based nanoparticles, such as bare Fe, sulfidized Fe (S-Fe) and palladized Fe (Pd-Fe). However, issues including particle agglomeration, difficulties in recycling and particle leaching have been reported to hinder the application and wide usage of these techniques. The integration of nanoparticles and membranes...

A Personalized Approach to Professional Development Through a Community of Practice

Kelly I. Cua
Personalized learning has gained traction in the United States as schools look to improve student learning through means that are less focused on standardized tests and are more focused on individualized student needs (Cavanagh, 2014). To successfully implement a new learning initiative such as personalized learning, high-caliber training must be provided. Research indicates a teacher's expertise and effectiveness account for the most significant difference in student achievement (Ferguson, 2001; Hattie, 2012), and therefore quality teacher...

Graph-Theoretic Simplicial Complexes, Hajos-type Constructions, and k-Matchings

Julianne Vega
A graph property is monotone if it is closed under the removal of edges and vertices. Given a graph G and a monotone graph property P, one can associate to the pair (G,P) a simplicial complex, which serves as a way to encode graph properties within faces of a topological space. We study these graph-theoretic simplicial complexes using combinatorial and topological approaches as a way to inform our understanding of the graphs and their properties....

Two Analytical Essays

Abigail Rueger
These two essays address different issues regarding Lieder. Chapter 1 discusses moon topoi and traces the development of these topics from “naïve” in Gluck’s works to “sentimental” in the songs of Fanny Hensel, based on the philosophical ideas of Friedrich Schiller. Chapter 2 focuses on specific translation theory, drawing on work from Mona Baker and Zhang Qun-Xing, arguing that one cannot compare two song settings of different translations of the same poem, since the translator’s...
