Creating Change In Pediatric Health Disparities: Utilizing Systemsbased Thinking To Overcome Disparities Affecting Pediatric Type 1 Diabetes In Kentucky, Sydney Speed

Lewis Honors College Thesis Collection

Healthcare disparities are perpetuated and upheld for patients with type 1 diabetes (T1D) in rural and underserved urban areas of Kentucky. By adopting systems-based thinking, we can identify areas of the healthcare system to change to eliminate these disparities. Namely, key leverage points of this system include distribution and utilization of resources, finances and the movement of money, and communication pathways. To address the disparities surrounding pediatric T1D in Kentucky, a state-wide medical event called Kentucky Diabetes Family Day (KDFD) was hosted. The focus of this event was to lessen the effects of these specific healthcare disparities by altering key …

Early Childhood Language And Literacy Development Programs For Autism Spectrum Disorder And D/Deaf And Hard-Of-Hearing Students, Mayson Spillman

Lewis Honors College Thesis Collection

This paper examines several popular approaches in the United States for enhancing early childhood literacy and language development in two special education populations— d/Deaf or hard-of-hearing (d/DHH) students and students with autism spectrum disorder (ASD). In addition to examining the effectiveness of these approaches, I adopt an educational equity lens to describe how variability in implementation can impact outcomes for these children. Based on my critical reading of the literature, I offer three broad recommendations for school psychologists: (1) Carefully consider dosage and fidelity of implementation, (2) Use caution when modifying existing interventions for these populations, and (3) Increase in-service …

Effects Of Translocation On Eastern Black-Tailed Rattlesnakes (Crotalus Ornatus) In The Northern Chihuahuan Desert, Jacob A. Coffman

Lewis Honors College Thesis Collection

AS HUMANITY continues to grow and expand, we inevitably encroach on wildlife habitat. This can create conflict between humans and wildlife. Human wildlife conflict usually occurs when humans are near areas where wildlife typically reside. A prime example is a farmer coming into conflict with animals that predate their seeds or livestock. The most common response to this problem in many areas is lethal control to prevent economic loss (Dickman 2010). This seems like an immediate resolution of the conflict in the human’s perspective, but this action can have many adverse effects. This killing may result in negative social outcry, …

Evaluation Of Academic Detailing To Educate Clinicians Regarding Childhood Lead Poisoning Prevention: A Pilot Study, Nicholas C. Newman, Jacqueline M. Knapke, Rachael Kiniyalocts, John Belt, Erin N. Haynes

UK CARES Faculty Publications

Context: Environmental exposures are associated with approximately 19% of disease globally, and exposure to neurotoxic chemicals is estimated to cost the United States $50 billion per year. Despite calls from the Institute of Medicine to increase training for clinicians regarding environmental health since the 1990s, there is still little instruction in environmental health for clinicians. This leaves gaps in knowledge that need to be bridged through outreach and education to practicing clinicians. Academic detailing (AD) is an educational intervention associated with improved prescribing practices in healthcare professionals but has not been applied to preventive or environmental health. Childhood lead exposure …

Asynchronous E-Training And Coaching To Indonesian Parents: Naturalistic Strategies To Support Language Development Of Children With Social-Communication Delays, Ndaru Prapti

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

The study is about virtual training and coaching to Indonesian parents of preschool-age children with social-communication delays to implement naturalistic intervention. These intercontinental coaching sessions were delivered asynchronously because of the time difference between the coach and the participants and internet bandwidth barrier in some rural areas in Indonesia. Multiple-baseline design across behaviors was utilized to determine the effect of asynchronous training and coaching program to teach three Indonesian parents three naturalistic strategies (i.e., modeling, mand-model, and time delay) during natural routines. Parent-child dyads video-recorded their interaction before and after intervention.

The intervention was started by learning the strategies, video-recorded …

Automatic Transcription Of Northern Prinmi Oral Art: Approaches And Challenges To Automatic Speech Recognition For Language Documentation, Connor Bechler

Theses and Dissertations--Linguistics

One significant issue facing language documentation efforts is the transcription bottleneck: each documented recording must be transcribed and annotated, and these tasks are extremely labor intensive (Ćavar et al., 2016). Researchers have sought to accelerate these tasks with partial automation via forced alignment, natural language processing, and automatic speech recognition (ASR) (Neubig et al., 2020). Neural network—especially transformer-based—approaches have enabled large advances in ASR over the last decade. Models like XLSR-53 promise improved performance on under-resourced languages by leveraging massive data sets from many different languages (Conneau et al., 2020). This project extends these efforts to a novel context, applying …

Bicategorical Traces And Cotraces, Justin Barhite

Theses and Dissertations--Mathematics

Familiar constructions like the trace of a matrix and the Euler characteristic of a closed smooth manifold are generalized by a notion of trace of an endomorphism of a dualizable object in a bicategory equipped with a piece of additional structure called a shadow functor. Another example of this bicategorical trace, in the form of maps between Hochschild homology of bimodules, appears in a 1987 paper by Joseph Lipman, alongside a more mysterious ”cotrace” map involving Hochschild cohomology. Putting this cotrace on the same category-theoretic footing as the trace has led us to propose a ”bicategorical cotrace” in a closed …

Hiding In Plain Sight: How Imperfect Ingredient Transformation Impact Consumer Preference For Rescue-Based Food, Anna De Visser-Amundson, John Peloza, Mirella Kleijnen, Aylin Aydinli

Marketing & Supply Chain Faculty Publications

Rescue-based food (RBF) – food products often made from ingredients that are not able to be sold due to aesthetic imperfections – represent an opportunity to reduce food waste. However, despite consumers’ desire to act prosocially, preference for such products is negatively impacted by the perception that the imperfect ingredients reduce the quality of RBF. Across two studies, one field study and one controlled experiment, we demonstrate that a higher level of ingredients transformation can positively impact demand for RBF. Specifically, when the transformation makes the physical appearance of the initial imperfect ingredients less discernable (e.g., pureed) consumer demand increases …

Examining A Blood Biomarker Approach To Blood-Brain Barrier Disruption, Samantha Ford

Theses and Dissertations--Medical Sciences

Blood-brain barrier disruption has been identified to associate with the pathogenesis several neurological diseases such as dementia [1, 2], multiple sclerosis[3, 4], acute or chronic cerebral ischemia[5], brain trauma[5], meningitis[5], encephalitis[5], stroke[6], and seizures[7]. Being able to effectively identify blood-brain barrier disruption is limited in methodology. The current standard is using a cerebrospinal fluid (CSF) albumin to serum albumin index, which requires the use of a lumbar puncture. A novel method of identifying blood-brain barrier disruption utilizing blood biomarkers is proposed in this study. Participants in this study had previously collected blood and CSF samples, which were analyzed to compare …

Comparing Indirect Assessment Results To A Direct Function Focused Preference Assessment To Identify Potential Reinforcers To Increase Task Completion In A School Setting, Kailee Joy Matthews

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

In the present study, a concurrent operant analysis (COA) was conducted for one elementary aged student in a publicly funded school to determine if the results yielded an interpretable outcome to identify a potential reinforcer to increase work completion. A simultaneous treatments design was used during the COA to assess choice making behavior. The results of the COA indicated the student’s choice making behavior was maintained by access to attention. An indirect measure of motivation was used as a secondary assessment to identify a potential reinforcer to increase work completion and to determine if the results would align with the …

Rnai-Mediated Gene Silencing In The Exotic Redbay Ambrosia Beetle, Xyleborus Glabratus, And Insect-Fungal Interactions Within The Laurel Wilt Complex, Morgan Christine Knutsen

Theses and Dissertations--Entomology

Laurel wilt disease (LWD) is a lethal vascular disease impacting lauraceous hosts caused by Harringtonia lauricola, the fungal symbiont of the redbay ambrosia beetle (Xyleborus glabratus Eichoff) (RAB) (Coleoptera: Curculionidae). LWD has caused tree mortality throughout the southeastern United States and is continuing to spread into new regions. Current management methods have not been successful in preventing spread, warranting investigation into innovative techniques including RNA interference (RNAi).

Elongation factor-1 alpha (ef1a) and actin (act) were established as stably expressed reference genes after exposing beetles to different photoperiod, temperature, and dsRNA exposure. After RAB oral …

Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera), Rebecca R. Westwick

Theses and Dissertations--Entomology

An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.

Social insects such as honey bees provide an excellent opportunity to better …

Epigenetic Regulation Of Insect Development, Yaoyu Jiao

Theses and Dissertations--Entomology

Insects undergo a series of distinct life stages such as egg, larva and pupa to develop into mature adults capable of reproduction throughout their life cycle. In the larval stage, insects experience the fastest growth with voracious feeding and multiple cuticle shedding resulting in hundreds-of-fold increasing of size. During metamorphosis, insects stop increasing body size but go through dramatic tissue transformation, developing wings and other adult features. The characteristic mode of insect development, especially the metamorphosis, makes insects the most successful group of animals on the earth. However, the epigenetic mechanisms behind insect development remain elusive. Studying the epigenetic regulation …

A Phenomenological Study Of Inclusive And Equitable Teaching Practices Among Faculty At A Research-Intensive Institution, Adeola Christianah Ogunade

Theses and Dissertations--Education Sciences

The increasing enrollment of diverse students in the US higher education institutions has given rise to discussions on how to meet the academic needs of minority students. Non-faculty members have implemented programs and initiatives that indirectly improve minority students' educational outcomes. Less explored is the role of faculty in ensuring that minority students thrive academically. This phenomenological qualitative study explores the general orientation of faculty toward inclusive and equitable teaching (IET). Specifically, it looked at how faculty define and experience IET, factors that motivated their use of IET, and barriers to implementing IET in higher education. Eight faculty from different …

How Principals Foster A Culture Of Student Voice, Anne Stewart Demott

Theses and Dissertations--Education Sciences

Student voice is a key component of educational leadership, yet school leaders remain confounded about how to succinctly define student voice, how to offer opportunities for students that position them as decision-makers in their schools, and how to integrate student voice into their daily practice, much less transform school cultures into vibrant, student-centered communities of learning. The purpose of this study was to develop an understanding of how high school principals define student voice, the opportunities they provide for student voice in their schools, and the strategies they implement to foster cultures of student voice.

The study uses a sequential …

Inclusion For Students With Intellectual Disabilities: A Philosophical Reconstruction Of The Student To Expand Access And Its Benefits, Derek Thomas Myles Daskalakes

Theses and Dissertations--Education Sciences

This dissertation attempts a philosophical rethinking of the concept of the student in educationally relevant disability law for the sake of expanding access to general education settings for students with intellectual disabilities (ID), without committing to the approach known as full inclusion. I show that students with ID receive significantly less access to general education settings in comparison to other student populations, and that empirical studies show this to be harmful to their learning and developmental outcomes. Discussion of this problem in the inclusion literature assumes one of two positions that separately support either maintaining the status quo regarding the …

Evaluating Microlearning Strategies In The Corporate Environment: A Comparative Mixed Methods Study Using The Kirkpatrick Model, Megan Laird Reynolds

Theses and Dissertations--Education Sciences

Corporate training and development, despite their significance as primary learning strategies for adults, have received limited research attention. This study addresses this gap by evaluating and comparing the effectiveness of video-based and digital job aid procedural-based microlearning in a corporate setting, utilizing most of the Kirkpatrick Model: learner satisfaction, knowledge retention, and behavior change. Employing a mixed methods approach to gain a comprehensive understanding of microlearning’s application and potential for improving business outcomes, the study incorporates pre- and post-tests, participant interviews, and self-reported questionnaires. Thirty participants completed the study, with equal representation (15 participants each) for both modalities, and interviews …

A Laboratory And Numerical Investigation Of The Strength Of Irregularly Shaped Pillars, Zachary Wedding

Theses and Dissertations--Mining Engineering

Underground mining operations utilize the room-and-pillar mining method that extracts the orebody and creates ‘rooms’ and leaves the remaining in-situ material as ‘pillars’ to support the overburden. Room-and-pillar mines are traditionally designed in square or rectangular-shaped pillars. This work presents laboratory experiments testing the compressive strengths of specimens modeled after square and parallelogram-shaped pillars and numerical models of square and -parallelogram-shaped pillar systems. The uniaxial compressive strength of the specimens’ shape and the observations of the extent of the specimen core post-failure were analyzed. There was insufficient evidence from the laboratory experiments to conclude that there is a difference in …

Gauging The Mass Of Metals In The Gas Phase Of Galaxies From The Local Universe To The Epoch Of Reionization, K. E. Heintz, Alice E. Shapley, Ryan L. Sanders, M. Killi, D. Watson, G. Magdis, F. Valentino, M. Ginolfi, D. Narayanan, T. R. Greve, J. P. U. Fynbo, D. Vizgan, S. N. Wilson

Physics and Astronomy Faculty Publications

The chemical enrichment of dust and metals are vital processes in constraining the star formation history of the universe. These are important ingredients in the formation and evolution of galaxies overall. Previously, the dust masses of high-redshift star-forming galaxies have been determined through their far-infrared continuum, however, equivalent, and potentially simpler, approaches to determining the metal masses have yet to be explored at z ≳ 2. Here, we present a new method of inferring the metal mass in the interstellar medium (ISM) of galaxies out to z 8, using the far-infrared [C II]- 158† μm emission line as a proxy. …

Jwst/Nirspec Balmer-Line Measurements Of Star Formation And Dust Attenuation At Z ∼ 3–6, Alice E. Shapley, Ryan L. Sanders, Naveen Reddy, Michael W. Topping, Gabriel B. Brammer

Physics and Astronomy Faculty Publications

We present an analysis of the star formation rates (SFRs) and dust attenuation properties of star-forming galaxies at 2.7 ≤ z < 6.5 drawn from the Cosmic Evolution Early Release Science Survey. Our analysis is based on JWST/NIRSpec Micro-Shutter Assembly R ∼ 1000 spectroscopic observations covering approximately 1-5 μm. Our primary rest-frame optical spectroscopic measurements are Hα/Hβ Balmer decrements, which we use as an indicator of nebular dust attenuation. In turn, we use Balmer decrements to obtain dust-corrected Hα-based SFRs (i.e., SFR(Hα)). We construct the relationship between SFR(Hα) and stellar mass (M _*) in three bins of redshift (2.7 ≤ z < 4.0, 4.0 ≤ z < 5.0, and 5.0 ≤ z < 6.5), which represents the first time the star-forming main sequence has been traced at these redshifts using direct spectroscopic measurements of Balmer emission as a proxy for SFR. In tracing the relationship between SFR(Hα) and M _* back to such early times (z > 3), it is essential to use a conversion factor between Hα and SFR that accounts for the subsolar metallicity prevalent among distant galaxies. We also use measured Balmer decrements to investigate the relationship between dust attenuation and stellar mass out to z ∼ 6. The lack of significant redshift evolution in attenuation at fixed stellar mass, previously confirmed using Balmer decrements out …

Azimuthal Anisotropy Measurement Of (Multi)Strange Hadrons In Au+Au Collisions At √𝑠𝑁⁢𝑁=54.4 Gev, Star Collaboration

Physics and Astronomy Faculty Publications

Azimuthal anisotropy of produced particles is one of the most important observables used to access the collective properties of the expanding medium created in relativistic heavy-ion collisions. In this paper, we present second (v2) and third (v3) order azimuthal anisotropies of KS0, φ, Λ, Ξ, and ω at midrapidity (|y|< 1) in Au+Au collisions at sNN=54.4 GeV measured by the STAR detector. The v2 and v3 are measured as a function of transverse momentum and centrality. Their energy dependence is also studied. v3 is found to be more sensitive to the change in the center-of-mass energy than v2. Scaling by constituent quark number is found to hold for v2 within 10%. This observation could be evidence for the development of partonic collectivity in 54.4 GeV Au+Au collisions. Differences in v2 and v3 between baryons and antibaryons are presented, and ratios of v3/v23/2 are studied and motivated by hydrodynamical calculations. The ratio of v2 of φ mesons to that of antiprotons [v2(φ)/v2(p¯)] shows centrality dependence at low transverse momentum, presumably resulting from the larger effects from hadronic interactions on antiproton v2.

Beam Energy Dependence Of Fifth- And Sixth-Order Net-Proton Number Fluctuations In Au + Au Collisions At Rhic, Star Collaboration

Physics and Astronomy Faculty Publications

We report the beam energy and collision centrality dependence of fifth and sixth order cumulants (C5, C6) and factorial cumulants (κ5, κ6) of net-proton and proton number distributions, from center-of-mass energy (sNN) 3 GeV to 200 GeV Au+Au collisions at RHIC. Cumulant ratios of net-proton (taken as proxy for net-baryon) distributions generally follow the hierarchy expected from QCD thermodynamics, except for the case of collisions at 3 GeV. The measured values of C6/C2 for 0%-40% centrality collisions show progressively negative trend with decreasing energy, while it is positive for the lowest energy studied. These observed negative signs are consistent with …

Measurement Of Sequential ϒ Suppression In Au + Au Collisions At √Snn = 200 Gev With The Star Experiment, Star Collaboration

Physics and Astronomy Faculty Publications

We report on measurements of sequential ϒ suppression in Au+Au collisions at sNN=200 GeV with the STAR detector at the Relativistic Heavy Ion Collider (RHIC) through both the dielectron and dimuon decay channels. In the 0%-60% centrality class, the nuclear modification factors (RAA), which quantify the level of yield suppression in heavy-ion collisions compared to p+p collisions, for ϒ(1S) and ϒ(2S) are 0.40±0.03(stat)±0.03(sys)±0.09(norm) and 0.26±0.08(stat)±0.02(sys)±0.06(norm), respectively, while the upper limit of the ϒ(3S) RAA is 0.17 at a 95% confidence level. This provides experimental evidence that the ϒ(3S) is significantly more suppressed than the ϒ(1S) at RHIC. The level of …
