Higher-Order Cumulants And Correlation Functions Of Proton Multiplicity Distributions In √Snn = 3 Gev Au+Au Collisions At The Rhic Star Experiment, The Star Collaboration

Physics and Astronomy Faculty Publications

We report a measurement of cumulants and correlation functions of event-by-event proton multiplicity distributions from fixed-target Au+Au collisions at √sNN = 3 GeV measured by the STAR experiment. Protons are identified within the rapidity (y) and transverse momentum (pT ) region −0.9 < y < 0 and 0.4 < pT < 2.0 GeV/c in the center-of-mass frame. A systematic analysis of the proton cumulants and correlation functions up to sixth order as well as the corresponding ratios as a function of the collision centrality, pT , and y are presented. The effect of pileup and initial volume fluctuations on these observables and the respective corrections are discussed in detail. The results are compared to calculations from the hadronic transport UrQMD model as well as a hydrodynamic model. In the most central 5% collisions, the value of proton cumulant ratio C4/C2 is negative, drastically different from the values observed in Au+Au collisions at higher energies. Compared to model calculations including lattice QCD, a hadronic transport model, and a hydrodynamic model, the strong suppression in the ratio of C4/C2 at 3 GeV Au+Au collisions indicates an energy regime dominated by hadronic interactions.

Cardinal's Blues: Implementation Of A School-Based Cognitive Behavioral Therapy Program For Jefferson County Public Schools In Louisville, Kentucky, Loui Chang

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

With the increasing rate of adolescent depression and anxiety1 2, developing mental health interventions is necessary. Many adolescents’ times spent in schools increased compared to 20 years ago5, which makes school-based intervention programs suitable for reaching adolescent population effectively. Though there are numerous treatment providers available in Jefferson County, Kentucky, the school-based prevention programs addressing adolescent’s negative mental health outcomes have never been implemented. The Blueprints for Healthy Youth Development developed a program called the Blues Program24. The Blues Program provides an adapted version of group Cognitive Behavioral Therapy sessions to train and educate adolescents coping skills and cognitive restructuring24. …

The Role Of Authenticity In The Link Between Self-Determination, Gender Minority Stress, Psychological Well-Being And Distress In Transgender, Nonbinary, And Gender Expansive Individuals, Zakary Alexander Clements

Theses and Dissertations--Educational, School, and Counseling Psychology

Transgender, nonbinary, and gender expansive individuals (TNB and GE) have the same basic psychological needs (BPN) for self-determination as their cisgender counterparts yet face unique gender minority stressors (GMS) that may impact psychological distress and well-being. Authenticity is an important factor that may also affect psychological well-being and distress in TNB and GE people. Few research studies have examined BPN attainment or GMS factors and psychological well-being and distress. The role of authenticity, which is associated with psychological well-being in cisgender samples, has yet to be examined in TNB and GE people on the context of BPN attainment or GMS. …

Exploration Of Factors Associated With Rural Appalachian Women's Use Of Buprenorphine Prior To Incarceration, Kelsey A. Redmayne

Theses and Dissertations--Educational, School, and Counseling Psychology

The Gelberg-Anderson Behavioral Model for Vulnerable Populations was used to identify factors related to buprenorphine use in general and through diversion (versus formal treatment) among rural Appalachian women using substances in the six months prior to their incarceration. This study is a secondary analysis of data from interviews completed with rural Appalachian women (N=400) residing in rural Kentucky jails. Independent variables were analyzed using chi square and independent t-tests for buprenorphine use generally and diverted buprenorphine use. The significant predictors were then evaluated through hierarchical logistic regression to explore which factors account for the most variance in general …

Conserved Novel Interactions Between Post-Replicative Repair And Mismatch Repair Proteins Have Differential Effects On Dna Repair Pathways, Anna K. Miller

Theses and Dissertations--Toxicology and Cancer Biology

DNA mismatch repair (MMR) is the DNA repair mechanism that repairs base-base mispairs and small insertions and deletions remaining after replication. MMR is also required for apoptosis after certain types of exogenous DNA damage that result in damage-associated mispairs. The basic MMR mechanism is well understood; however, proteins associated with MMR continue to be identified. The roles of these interacting proteins in MMR are largely unknown. We have identified the yeast protein Rad5 as a novel interactor of the critical MMR proteins Msh2 and Mlh1. Rad5 is a DNA helicase and E3 ubiquitin ligase involved in post-replicative repair. However, to …

Data For "Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera)"", Rebecca R. Westwick, Clare C. Rittschof, Gavin P. Brackett, Cameron E. Brown, Bethany J. Ison, Zainulabbeudin Syed, Anna M. Foose

Entomology Research Data

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 …

A Comparative Analysis Of Applied Behavior Analysis And The Montessori Method, Emily Webb

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

The Montessori method is a multi-sensory curriculum design based on Dr. Maria Montessori’s observations of the positive outcomes a multi-sensory educational approach had when working with children with disabilities; however, there is little empirical data to support the outcomes of using the Montessori method to teach children with disabilities. Despite the limited amount of quantitative research on the Montessori method and early childhood special education, studies suggest Montessori educators are open to professional development on working with children with disabilities and are willing to implement other methods to provide support for those children while still maintaining the integrity of the …

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

Parents of young children with or at risk for disabilities face added stress and challenges every day. This study implemented a rapid coaching intervention to teach a parent naturalistic language interventions such as mapping language onto their child's play, narrating their own play, and arranging the environment. In addition, parents were trained to use a milieu teaching procedure. In addition, a pre-service behavior interventionist and speech-language pathologist collaborated on selecting instructional targets for the child.

Magnetotelluric Insights Into The Formation And Reactivation Of Trans-Crustal Shear Zones In Precambrian Basement Of The Eastern U.S. Midcontinent, Benjamin S. Murphy, Michael S. Delucia, Stephen Marshak, Dhananjay Ravat, Paul A. Bedrosian

Earth and Environmental Sciences Faculty Publications

Three-dimensional inversion of regional long-period magnetotelluric (MT) data re- veals the presence of two distinct sets of high-conductivity belts in the Precambrian basement of the eastern U.S. Midcontinent. One set, beneath Missouri, Illinois, Indiana, and western Ohio, is defined by northwest– southeast-oriented conductivity structures; the other set, beneath Kentucky, West Vir- ginia, western Virginia, and eastern Ohio, in- cludes structures that are generally oriented northeast–southwest. The northwest-trend- ing belts occur mainly in Paleoproterozoic crust, and we suggest that their high con- ductivity values are due to graphite precipi- tated within trans-crustal shear zones from intrusion-related CO2-rich fluids. Our MT inversion …

Operationalizing A Culture For Successful Lean Transformations: A Framework And Model-Based Tools, Amir Najarzadeh Dr.

Theses and Dissertations--Manufacturing Systems Engineering

Lean manufacturing has been embraced by many companies as a business model to promote operational excellence. However, a high percentage of lean implementation attempts have failed; many organizations have not been able to sustain continuous improvements to achieve lean transformations. This failure is often attributed to the sole focus on the hard-side (tools) of lean, at the expense of the soft side (culture). The majority of research exploring the cultural dimensions of lean either aims to increase awareness about culture or addresses it only in a cursory manner. To bridge this gap this study aims to identify and assess the …

BACKGROUND: The regional heterogeneity of vascular components and transcriptomes is an important determinant of aortic biology. This notion has been explored in multiple mouse studies. In the present study, we examined the regional heterogeneity of aortas in nonhuman primates.

METHODS: Aortic samples were harvested from the ascending, descending thoracic, suprarenal, and infrarenal regions of young control monkeys and adult monkeys with high fructose consumption for 3 years. The regional heterogeneity of aortic structure and transcriptomes was examined by histological and bulk RNA sequencing analyses, respectively.

RESULTS: Immunostaining of CD31 and αSMA (alpha-smooth muscle actin) revealed that endothelial and smooth muscle …

Utilizing Precision Technologies To Validate A Real-Time Location System For Dairy Cattle And Monitor Calf Behaviors During Heat Stress, Emily Rice

Theses and Dissertations--Animal and Food Sciences

With the increase in on-farm precision dairy technologies (PDT) utilization, large quantities of information are readily available to producers. A more recently available technology for use in livestock species is the real-time location system. These technologies offer dairy producers the opportunity to monitor and track real-time locations of cows, track locomotion patterns, and summarize specific area usage. However, the usefulness of these insights is heavily dependent on the performance of the technology. Therefore, the first objective of this dissertation was to assess the positioning recording performance and the usefulness of the data recorded of a real-time location system (Smartbow GmbH; …

Effects Of Biosynthesized Bromoform On Enteric Methane Production, Animal Performance And Tissue Residues In Cattle, Sydney Davis

Theses and Dissertations--Animal and Food Sciences

Greenhouse gas (GHG) emissions have been implicated in global warming and extreme climate change conditions. The Environmental Protection Agency (EPA) has identified agriculture, more specifically cattle production, as a major contributor to global GHG production. When expressed as liters of gas, CO2 is considered the primary GHG produced, however, in terms of global warming potential (GWP), CH4 has 25-times greater potential than that of CO2. Due to the elevated GWP of CH4, we have constructed a series of experiments to investigate the use of a halogenated CH4 analogue derived from kelp (i.e., bromoform) as an inhibitor of enteric CH4 production …

Interface: Technology & Portraiture, Mullins Sydney

Graduate Thesis Exhibition Catalogue Gallery, 2023

In Interface, five Kentucky-area artists explore a new language of representation with the aid of digital tools like Artificial Intelligence (AI) and Automatic Facial Recognition Software (AFR). Some artists use algorithms to alter celebrity faces beyond recognition, others feed data sets of existing art to AI models in an attempt to generate portraits of no one in particular. Others still create tools for understanding the very act of facial recognition or obfuscation. All have one thing in common: they wish to stretch the limits of and critique the genre of portraiture, as well as to cause viewers to question …

An Investigation Of Individualized Education Programs For Students With Autism, Jordan Findley

Theses and Dissertations--Educational, School, and Counseling Psychology

Autism is one of the fastest growing educational disability groups (U.S. Department of Education, Office of Special Education Programs, 2021). The Individuals with Disabilities Education Improvement Act (IDEIA, 2004) ensures all students have access to a free and appropriate public education. Individualized Education Programs (IEP) have been described as central to IDEIA (2004) and are the most common service received by children with autism (Berrcera et al., 2017; Yell et al., 2003). Despite the frequent use of the IEP in service provision for students with autism, there is relatively little research on the content and quality of IEPs for students …

Quality Control Methods Through Pre-Determination Of Fields For Usrap Projects, Zachary Heath

Theses and Dissertations--Civil Engineering

The United States Road Assessment Program (usRAP) was designed to rate highways for their ability to protect road users and to make recommendations to engineers and policy makers for investments to enhance road safety. The program is heavily dependent on local road data or characteristics. Pre-populating usRAP requires coders to evaluate sixty-six attributes at 100-meter intervals along a subject highway. In this thesis, methods for obtaining and assuring the quality of some of the usRAP data elements are proposed. Kentucky Transportation Cabinet Highway Information System (HIS) data are used as “ground truth” for roadway grade and curvature. Methods of using …

Historical And Forecasted Kentucky Specific Slope Stability Analyses Using Remotely Retrieved Hydrologic And Geomorphologic Data, Daniel M. Francis

Theses and Dissertations--Civil Engineering

Hazard analyses of rainfall-induced landslides have typically been observed to experience a lack of inclusion of measurements of soil moisture within a given soil layer at a site of interest. Soil moisture is a hydromechanical variable capable of both strength gains and reductions within soil systems. However, in situ monitoring of soil moisture at every site of interest is an unfeasible goal. Therefore, spatiotemporal estimates of soil moisture that are representative of in-situ conditions are required for use in subsequent landslide hazard analyses.

This study brings together various techniques for the acquisition, modeling, and forecasting of spatiotemporal retrievals of soil …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …
