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...

Does breeding season variation affect evolution of a sexual signaling trait in a tropical lizard clade?

Levi Gray, Anthony Barley, David Hillis, Carlos Pavón-Vázquez, Steven Poe & Brittney White
Sexually selected traits can be expected to increase in importance when the period of sexual behavior is constrained, such as in seasonally restricted breeders. Anolis lizard male dewlaps are classic examples of multifaceted signaling traits, with demonstrated intraspecific reproductive function reflected in courtship behavior. Fitch and Hillis found a correlation between dewlap size and seasonality in mainland Anolis using traditional statistical methods. Here, we present two tests of the Fitch-Hillis Hypothesis using new phylogenetic and...

Data from: Nutrient availability controls the impact of mammalian herbivores on soil carbon and nitrogen pools in grasslands

Judith Sitters, E.R. Jasper Wubs, Elisabeth S. Bakker, Thomas W. Crowther, Peter B. Adler, Sumanta Bagchi, Jonathan D. Bakker, Lori Biederman, Elizabeth T. Borer, Elsa E. Cleland, Nico Eisenhauer, Jennifer Firn, Laureano Gherardi, Nicole Hagenah, Yann Hautier, Sarah E. Hobbie, Johannes M.H. Knops, Andrew S. MacDougall, Rebecca L. McCulley, Joslin L. Moore, Brent Mortensen, Pablo L. Peri, Suzanne M. Prober, Charlotte Riggs, Anita C. Risch … &
Grasslands have been subject to considerable alteration due to human activities globally, including widespread changes in populations and composition of large mammalian herbivores and elevated supply of nutrients. Grassland soils remain important reservoirs of carbon (C) and nitrogen (N). Herbivores may affect both C and N pools and these changes likely interact with increases in soil nutrient availability. Given the scale of grassland soil fluxes, such changes can have striking consequences for atmospheric C concentrations...

Ancestral state reconstruction for regeneration and autotomy in arthopods and reptiles

Jeremy Van Cleve, Luc Dunoyer & Ashley Seifert
Some form of regeneration occurs in all lifeforms and extends from single-cell organisms to humans. The degree to which regenerative ability is distributed across different taxa, however, is harder to ascertain given the potential for phylogenetic constraint or inertia, and adaptive processes to shape this pattern. Here, we examine the phylogenetic history of regeneration in two groups where the trait has been well-studied: arthropods and reptiles. Because autotomy is often present alongside regeneration in these...

Toxin or medication? Immunotherapeutic effects of nicotine on a specialist caterpillar

Michael Garvey, Justin Bredlau, Karen Kester, Curtis Creighton & Ian Kaplan
1. A core tenant in the field of ecological immunology is that immune responses trade off with other physiological functions due to resource-allocation costs. Caterpillars, for example, tend to exhibit reduced immune responses when reared on more toxic food plants due to a cost from detoxifying or sequestering secondary metabolites, also known as the “vulnerable host hypothesis”. However, support for this hypothesis is mixed, and studies have not yet mechanistically isolated the relative contributions of...

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...

Kentucky Annual Economic Report 2020

Michael T. Childress, Michael W. Clark, William H. Hoyt & Simon Sheather
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...

A MULTI-METHOD INVESTIGATION OF THE MODERN SEDIMENTATION AND LATE HOLOCENE PALEOLIMNOLOGY OF JUNE LAKE (MONO COUNTY, CA), AND A SURVEY-BASED ANALYSIS OF NINTH GRADERS’ ATTITUDES TOWARDS GEOLOGY

Eva Lyon
Three distinct manuscripts comprise this dissertation. The first analyzes the modern sedimentary basin of June Lake, a small glacial lake in the eastern Sierra Nevada of California (USA) using a number of data sets, including bathymetry, surface sediment composition, and seismic stratigraphy. The seismic survey revealed sublacustrine morphological features that suggest the basin originated due to ice scour, as well as four acoustically distinct stratigraphic units that reflect the history of sedimentation following glacial scouring....

TOBACCO USE AND NICOTINE WITHDRAWAL AMONG PATIENTS WITH MENTAL ILLNESS

Yazan Al-Mrayat
People with mental illness (MI) are disproportionately affected by tobacco use compared to the general population. In fact, it is estimated that people with MI consume approximately 44% of cigarettes smoked in the United States. Moreover, the MI population is at greater risk for the negative social, economic, and health consequences associated with tobacco use and are reported to have 25-year shorter life expectancies than the general population. The impact of tobacco use is further...

Reserved for the Whole Earth

Eric Robsky Huntley
This dissertation examines geographic forms of evidence in the practices of landscape architects and geographers. I analyze evidence not only as an epistemic phenomenon, but as an aesthetic one, as well. Convincing an audience that the world is (or should be) one way and not another requires that knowledges be stacked, extended, and stitched together in a manner admissable to an audience. In the first two chapters, I use the case of the landscape architect...

Street Affects

Laçin Tutalar
This paper argues that affective moments between street musicians and the audience in Istanbul, Turkey suggest a loose connection to open and highly affective practices of hearing. The street brings them together during the moments of performance. The performance twists the power of sound that the musician makes and draws that into visualization of the moment, which underlines a peculiar affective attachment on the audience's side. The city's, musician's, and the listening practices' significance in...

Conversation Goals, Communication Satisfaction, and Relational Dynamics While Navigating Alzheimer’s Disease

Elizabeth Spencer
Currently there are more than 16 million unpaid Alzheimer’s disease and dementia caregivers in the United States. These caregivers are often family members of the person living with dementia, and as they navigate the process of giving care to the patient, they must also maintain relationships with each other. Families enter the dementia experience with a history of their relational experiences, and their relational experiences potentially change as they navigate family experiences after the dementia...

A FRAMEWORK FOR HETEROLOGOUS BIOSYNTHESIS OF NATURAL PRODUCTS IN MAMMALIAN CELLS VIA POLYMER-MEDIATED TRANSFECTIONS

Logan Warriner
With the promise to treat a multi-faceted list of serious inherited and acquired diseases, such as cancer, neurodegenerative and infectious diseases, and inherited genetic indications, gene therapy has continued to push the boundaries of traditional medicine since its earliest implementation. While much progress has been made, clinical success has largely remained elusive. Immunogenicity, difficulty producing commercially relevant quantities, and having a limited genetic payload still limits the ability of viruses to act as directed delivery...

IONIC BONDING CURRICULUM UNIT

Mary Lamar
This mixed methods study compared two groups of high school students’ understanding of the ionic bond and the dissolving process. A 5 lesson curriculum unit was developed using Taber’s electrostatic framework (1997) focusing on the electrostatic forces between ions compared to a molecular framework (business-as-usual) and the Next Generation Science Standards (NGSS Lead States, 2013). The lessons were developed to integrate spatially integrated experiences. Experimental (new curriculum unit) and business-as-usual (criss-cross method) students had their...

POPULATION PHARMACOKINETIC MODELING AND GENETIC ASSOCIATION ANALYSIS IN INFANTS WITH NEONATAL ABSTINENCE SYNDROME RECEIVING MORPHINE OR CLONIDINE

Fei Tang
Neonatal abstinence syndrome, or NAS, is a postnatal opioid withdrawal syndrome occurring in 55% to 94% of neonates as a result of in utero exposure to opioids. It has emerged as a significant public health issue, as its incidence more than quadrupled in the past decade. There is significant variability in disease severity and treatment outcomes in neonates with NAS due to patient-specific factors and treatment- or site-specific factors. To understand what contributes to variability...

COMPARING, CONTRASTING, AND EVALUATING SINGLE CASE RESEARCH DESIGNS AND DESCRIBING HOW TO APPLY COACHING TECHNIQUES IN AN APPLIED SETTING

Kasey Waddell
During the Spring 2020 semester, students within the applied behavior analysis/special education/interdisciplinary early childhood education program were conducting applied thesis projects within typical contexts as part of their fulfillment of the requirements of a master’s degree program. Due to the coronavirus disease 2019 (COVID-19), public schools and related facilities closed with no plans to reopen within the time frame to allow for graduation for students in the last semester of their graduate program. Students were...
