A Social Learning Approach To The Examination Of The Temporal Directionality Between Parenting Behavior And Early Adolescents' Affect., Shelby M. Burton
Electronic Theses and Dissertations
This study contributes to current literature by being the first to longitudinally examine the relation between early adolescents’ negative and positive affect and specific parenting behaviors. The five parenting behaviors examined in the current study are rooted within the social learning theory constructs of effective discipline (i.e., corporal punishment, inconsistent discipline), positive involvement (i.e., parental involvement), monitoring (i.e., poor monitoring and supervision), and social skills encouragement (i.e., positive parenting). Two research questions were addressed: (1) how are parenting behaviors at baseline associated with early adolescent-reported NA and PA at a later timepoint, and (2) how are early adolescents’ NA and …

Nitrogen-Doped Carbon Fiber Ultramicroelectrodes As Electrochemical Sensors For Detection Of Hydrogen Peroxide, Eric Wornyo
Nitrogen-Doped Carbon Fiber Ultramicroelectrodes As Electrochemical Sensors For Detection Of Hydrogen Peroxide, Eric Wornyo
Electronic Theses and Dissertations
Carbon fiber ultramicroelectrodes (CF-UMEs) are commonly used as electrochemical probes and sensors due to their small size, fast response, and high signal-to-noise ratio. Surface modification strategies are often employed on CF-UMEs to improve their selectivity and sensitivity for desired applications. However, many modification methods are cumbersome and require expensive equipment. In this study, a simple approach known as soft nitriding is used to prepare nitrogen-doped CF-UMEs (N-CF-UMEs). Nitrogen groups introduced via soft nitriding act as electrocatalytic sites for the breakage of O-O bonds during the reduction of peroxides like H2O2, a common target of biosensing strategies. …
Perceptions Of Resilience-Informed Education In Postsecondary Instructors, Chelsea L. Robertson
Perceptions Of Resilience-Informed Education In Postsecondary Instructors, Chelsea L. Robertson
Electronic Theses and Dissertations
Many studies have noted the detrimental impact adverse childhood experiences (ACEs) can have on individuals’ developmental trajectories and, as a result, the utilization of trauma-informed practices has been of increasing interest within the field of education. Most research on trauma-informed pedagogy is derived from samples of children in grades K-12, whereas research on trauma-informed teaching practices within higher education is comparatively scarce. The specific aims of the current investigation are two-fold. The first aim is to explore the effect of postsecondary instructors’ disciplinary specialization (i.e., person-thing orientation) on their receptivity to compassionate teaching practices. The second aim is to implement …
Economic Insecurity, Poverty, And Parental Alcohol Misuse, Joey Tucciarone
Economic Insecurity, Poverty, And Parental Alcohol Misuse, Joey Tucciarone
Electronic Theses and Dissertations
Because parental alcohol misuse is associated with numerous negative outcomes for drinkers and other family members, it is important to examine factors predictive of alcohol misuse patterns among parents living with at least one child under the age of 18. Two possible factors include economic insecurity and poverty. This study sought to address whether measures of economic insecurity (i.e., housing and/or food insecurity in the past 12 months) and a dichotomous measure of poverty predict parental binge drinking and parental heavy alcohol consumption in a large population-based sample. It was hypothesized that economic insecurity and poverty, analyzed separately, would predict …

Spatial Analyses Of Gray Fossil Site Vertebrate Remains: Implications For Depositional Setting And Site Formation Processes, David Carney
Electronic Theses and Dissertations
This project uses exploratory 3D geospatial analyses to assess the taphonomy of the Gray Fossil Site (GFS). During the Pliocene, the GFS was a forested, inundated sinkhole that accumulated biological materials between 4.9-4.5 mya. This deposit contains fossils exhibiting different preservation modes: from low energy lacustrine settings to high energy colluvial deposits. All macro-paleontological materials have been mapped in situ using survey-grade instrumentation. Vertebrate skeletal material from the site is well-preserved, but the degree of skeletal articulation varies spatially within the deposit. This analysis uses geographic information systems (GIS) to analyze the distribution of mapped specimens at different spatial scales. …

The exhibition serves to look at East Texas specifically as a microcosm of the social ramifications of the introduction of photography. The museum presents this project as a commentary and celebration of the culture of the region while being objective enough to discuss both the high points and the low points. The thesis project itself displays the best and most current …
Prediction Intervals: The Effects And Identification Of Sparse Regions For Nonparametric Regression Methods, Jackson Faires
Prediction Intervals: The Effects And Identification Of Sparse Regions For Nonparametric Regression Methods, Jackson Faires
Electronic Theses and Dissertations
In this work, we provide an overview of different nonparametric methods for prediction interval estimation and investigate how well they perform when making predictions in sparse regions of the predictor space. This sparsity is an extension to the more common concept of extrapolation in linear regression settings. Using simulation studies, we show that coverage probabilities using prediction intervals from quantile k-nearest neighbors and quantile random forest can be biased to low or too high from the nominal level under various situations of sparsity. We also introduce a test that can be used to see if a new data point lies …

This ability will facilitate timely intervention in both the learning and the teaching process in a variety of classroom settings. In this dissertation, an automatic students engagement measure is proposed through investigating three main engagement components of the engagement: the behavioural engagement, the emotional engagement and the cognitive engagement. The main goal of the proposed technology is to provide the instructors with a tool that could help them estimating …
Urban Teacher's Perspectives On Teaching Diverse Students., Julie Chancellor
Urban Teacher's Perspectives On Teaching Diverse Students., Julie Chancellor
Electronic Theses and Dissertations
Teachers who are mostly White often do not understand their cultural disconnect from their mostly non-White students (Blaisdell, 2016; King, 1991). Having teachers exposed to, and competent with, Culturally Responsive Pedagogy (CRP) (Ladson-Billings, 1995) and Culturally Sustaining Pedagogy (CSP) (Paris, 2012) can help bridge that divide. Since CSP is a relative newcomer to educational pedagogy, this study was designed to discover what CSP traits teachers have and how these traits impact their students. This qualitative case study is comprised of four teachers at one urban high school that has historically been designated as not making adequate progress. These teachers are …

Magnetic bead bioconjugates are functionalized with large amounts of …
Investigations Of Elastin Recoil On Molecular And Macroscopic Levels., Nour Mohammad Jamhawi
Investigations Of Elastin Recoil On Molecular And Macroscopic Levels., Nour Mohammad Jamhawi
Electronic Theses and Dissertations
Elastin is one of the most hydrophobic proteins, and it is extremely flexible when hydrated. The driving force for recoil is the decrease in entropy of the protein and/or the hydrating solvent. This dissertation is a study of both mechanisms. Following an introduction (Chapter 1), Chapters 2 and 3 investigate the recoil mechanism on the molecular level in the hydrating solvent and in the protein, respectively. Chapter 4 examines macroscopic properties of recoil by thermomechanics. Conclusions are discussed in Chapter 5. Using double quantum NMR, the deuterated water ordering at the elastin surface was studied quantitatively as a function of …
Oligodendrocyte Responses After Spinal Cord Injury., George Zach Wei
Oligodendrocyte Responses After Spinal Cord Injury., George Zach Wei
Electronic Theses and Dissertations
Recent studies demonstrate that neuroprotection strategies targeting the proteostasis network and components of its effector signaling pathways improve cell survival and motor recovery outcomes in several models of neuronal injury and degeneration. However, the individual contributions of these signaling pathways to the pathogenesis of spinal cord injury (SCI), white matter damage, and motor recovery have not yet been determined. Here, I explored the role of the HIF prolyl hydroxylase domain proteins (PHD/EGLN), effectors that can modulate stress responses activated by the proteostasis network, on motor function recovery after SCI. Furthermore, I identified previously unknown candidate mechanisms in an unbiased manner …
The Space Between: Listening Within Difference In Writing Center Consultations., Jessica S. B. Newman
The Space Between: Listening Within Difference In Writing Center Consultations., Jessica S. B. Newman
Electronic Theses and Dissertations
Writing center consultations are built of writer and consultant relationships and differences. Listening is a stance that facilitates navigation of these differences, yet it has long been undervalued. I investigated the roles of listening in writing center consultations, exploring the perspectives of writer and consultant participants. For this mixed methods case study, I collected observations, surveys, interviews, and asynchronous responses to follow-up questions. I also synthesized three listening theories that attend to relations between self and other: dialogic listening, rhetorical listening, and listening otherwise. Listening’s connections with openness, understanding, and power have many implications for the writing center. Listening involves …

Trends In Hysterectomy In Hospital And Ambulatory Settings In Kentucky 2017-2020., Felicia A. Pugh
Electronic Theses and Dissertations
Hysterectomy is the most common treatment for benign uterine conditions in the United States. Data suggest that one in nine women will have the procedure in their lifetime (1). Previous studies indicate that abdominal hysterectomy rates for non-malignancies are declining as alternative methods are increasing for decades; however, those trends do not apply for all women in the country (2-5). In this cross-sectional study, hysterectomy procedures completed between 2017-2020 are described in Kentucky Cabinet for Health and Family Services data. Multivariable logistic regression is used to assess the odds of abdominal hysterectomy for benign indications in Kentucky. Conclusion: Rates of …

In this study, I explore the Late Archaic and Woodland settlement patterns (3,000 BC – 1,000 AD) in the Daniel Boone National Forest, Kentucky, and surrounding region within the context of the intensification of horticulture. GIS predictive modelling via automated learning algorithms are employed to explore various environmental variables that may have influenced where and why horticultural intensification occurred. Predictive models using random forest and maximum entropy are created and compared for the Late Archaic and Woodland periods. Results show only minimal variance between the Late Archaic and Woodland settlement patterns within the study area with slope and elevation identified …
Concurrent Reporting Of Adverse Childhood Experiences Among Perspectives Of Adolescents And Caregivers., Katie J. Berghuis
Concurrent Reporting Of Adverse Childhood Experiences Among Perspectives Of Adolescents And Caregivers., Katie J. Berghuis
Electronic Theses and Dissertations
The consequences of Adverse Childhood Experience (ACE) events in youth have predominantly been studied through retrospective studies that assess adults’ first 18 years of life or caregiver report of ACEs in youth. Reliance on only caregiver report to discern ACEs is a limitation amongst prior studies as research has found that caregivers tend to underestimate ACEs among their children, and there is even a greater discrepancy of reporting between caregivers and youth 12 years and older. Therefore, this study investigated concurrent reporting of self-report ACE scores in adolescents – defined in this study as 12 to 20 years old – …
Bayesian Variable Selection Strategies In Longitudinal Mixture Models And Categorical Regression Problems., Md Nazir Uddin
Bayesian Variable Selection Strategies In Longitudinal Mixture Models And Categorical Regression Problems., Md Nazir Uddin
Electronic Theses and Dissertations
In this work, we seek to develop a variable screening and selection method for Bayesian mixture models with longitudinal data. To develop this method, we consider data from the Health and Retirement Survey (HRS) conducted by University of Michigan. Considering yearly out-of-pocket expenditures as the longitudinal response variable, we consider a Bayesian mixture model with $K$ components. The data consist of a large collection of demographic, financial, and health-related baseline characteristics, and we wish to find a subset of these that impact cluster membership. An initial mixture model without any cluster-level predictors is fit to the data through an MCMC …
