Restorative Strategies Used To Reduce Disproportionality In Texas Schools That Have Implemented Restorative Practices, Shenita Y. Alsbrooks

Electronic Theses and Dissertations

The purpose of this qualitative case study was to identify restorative practice strategies than can be used to reduce disproportionality in school discipline in Texas schools. Exclusionary discipline practices have created disproportionality in school discipline. While zero-tolerance policies are no longer considered effective in addressing conflict in schools, many schools are implementing restorative practices as a promising alternative. Restorative practices have shown to contribute to positive school culture, specifically by improving student achievement, improving attendance, improving student-teacher relationships, and lowering discipline issues. Interviews using semistructured questions were used to conduct this study. In this qualitative case study, participants at suburban …

Perceptions Of Migrant And Seasonal Head Start Parents About Childhood Vision Care Utilization, Felicia R. Thomas

Electronic Theses and Dissertations

The benefits of pediatric vision screening for very young children is not a new concept. However, not all children receive this valuable preventative intervention, or they do not receive an evaluation or examination to rule out or treat common visual refractive errors. This Doctor of Nursing Project sought to identify factors that impact a parent’s failure to follow up on recommendations for further evaluation or treatment following their child’s failed vision screening. The project utilized a phenomenological study to assess Migrant and Seasonal Head Start parents’ perceptions about their perceptions of the need for preventative vision screening and care. Three …

Electronic Theses and Dissertations

Introverted leaders are instrumental in building relationships and teams, setting benchmarks and pursuing academic goals, and planning and strategizing the implementation of performance initiatives. This qualitative case study illustrated how Organizational Leadership has been previously isolated to extraverts and clarifies the need for introverted leadership. The purpose of this study was to explore ways in which high school leaders identify themselves as introverts and demonstrate the strengths of introverted leadership within the parameters of their professional roles. This study followed three introverted administrators at a suburban Texas secondary campus. Participants were observed in their professional settings: in meetings, correspondence, duty …

Teachers Who Collaborate With A Professional Writing Organization: The Importance Of Critical Stance, Paul A. Viskanta

Electronic Theses and Dissertations

A wide body of research finds teacher preparation programs fail to address the complexity of writing instruction, especially for secondary English-language Arts teachers (Coker & Lewis, 2008; Graham, 2019; Wahleithner, 2018). Beliefs and knowledge about writing determine how teachers approach pedagogical practices (McCarthey & Mkhize, 2013). One of many contextualized social literacy practices, writing is always ideological (Gee, 2105; Moje & Lewis, 2007). Competing research philosophies complicate development of teachers' practices and impedes research dissemination (Coker & Lewis, 2008; Hillocks, 2008; National Writing Project & Nagin, 2006). Structures informing school-based writing limit the types of writing practices (Bazerman, 2016). Using …

Moving Past ‘One Size Fits All’: Developing A Trajectory Deviance Index For Dynamic Measurement Modeling, Yixiao Dong

Electronic Theses and Dissertations

Dynamic Measurement Modeling (DMM) is a recently developed measurement framework for gauging developing constructs (e.g., learning capacity) that conventional single-timepoint tests cannot assess. Like most measurement models, overall model fit indices of DMM do not indicate the measurement appropriateness for each included student. For this reason, other measurement modeling paradigms (e.g., Item-Response Theory; IRT) utilize person-fit or model appropriateness statistics to indicate whether a measurement model appropriately describes the data from each individual student. However, within the extant DMM framework, no statistical index has yet been developed for this purpose. Thus, the current project advanced a person-specific DMM Trajectory Deviance …

Observation Of New Particle Formation In The Northern Hemisphere At Altitude From 4 To 20 Km, Mohamed Saad

Electronic Theses and Dissertations

New particle formation (NPF) is investigated using measurements of aerosol size distributions and meteorological variables made in two continents, including USA and Europe. Despite the considerably different aerosol particle abundances among the sites, a common relationship was found between the characteristics of NPF events and the air mass convective and/or advective transport. CO and O3 act as tracers of tropospheric and stratospheric air, respectively, their statistical relationship can be used to quantify air mass characteristics and origins. The mixing ratio values of CO increased within the upper troposphere layer before/during NPF events, which may serve as an indicator of occurring …

The Place And Role Of Pharmacy Benefit Management (Pbm) Companies In Us Healthcare System, George Mattis Ii

Electronic Theses and Dissertations

On average, prescription drugs cost US consumers more than any other developed country in the world. US drug makers claim that intermediaries in the prescription drug supply chain, companies called pharmacy benefit managers (PBM), are forcing them to increase their drug prices. PBMs counter that the discounts they receive from drug makers are channeled to insurers. This thesis will examine the role that PBMs play in the prescription drug supply chain and determine what effect they have on drug prices. This thesis will utilize a comparative static model, Structure, Conduct, Performance (SCP) framework to analyze the pharmaceutical manufacturing and the …

Anger Bias In The Evaluation Of Crowds, Diana Mihalache

Electronic Theses and Dissertations

Although people are good at classifying emotions, they also make mistakes. These errors tend to be negatively biased and potentially serve a protective function. Research on biases in emotion perception has largely focused on perception of individual faces and little is known about biases in evaluations of crowds. In the first investigation, I conducted six experiments, evaluating anger bias—a tendency to judge facial expressions as angry—in the context of single faces and emotionally homogenous crowds. I found that observers were biased to classify faces as angry, especially when evaluating crowds. This amplified bias emerged in the context of perceptual uncertainty …

The Hotelling Valuation Principle: Does User Cost And Reserve Differentials Improve Validity?, Brian K. Hicks

Electronic Theses and Dissertations

The Hotelling Valuation Principal (HVP) implies that the value per unit of an in-ground exhaustible natural resource is equal to the current price less the cost of production. The assumptions required for this principle include a certain and homogenous reserve stock, unconstrained extraction, and constant costs. Extensive research has empirically investigated the HVP. This paper expands the HVP framework and relaxes the theory’s assumptions to account for reserve differentials. The results show that the original net price model is more closely aligned with developed reserve value, than total reserve value. In addition, this paper develops two- and three-factor net price …

Parental Self-Efficacy, Parenting Stress, And Mental Health Among Latina Mothers Of Young Children, Thania Galvan

Electronic Theses and Dissertations

Parenthood can increase the risk for mental health concerns, especially for Latina mothers. Poor maternal mental health can result in significant negative maternal and child outcomes, particularly if a mother’s mental health needs go unmet. In an attempt to better understand the factors that impact Latina mother’s mental health, this study explored the relations among parental self-efficacy, parenting stress, and mental health. It also explored mother’s self-reported resource availability and sociocultural factors as potential modifiable points of interventions in these relations.

Methods: The study was conducted using data from 132 Latina mothers that participated in a larger project examining stress …

So What, Now What? Using Social Media Activism To Inform Power-Conscious Prevention Of Gender-Based Violence, Andrea R. Thyrring

Electronic Theses and Dissertations

We will not end gender-based violence by responding to it. Experts and national organizations agree that effective primary prevention programs are essential to stopping harmful behaviors before they start (DeGue et al, 2014; American College Health Association, 2016; American College Health Association, 2018; Townsend, 2017; Schneider & Hirsch, 2018; McMahon et al, 2019), so much so that primary prevention to address gender-based violence on college campuses has been mandated by state and federal policy (SB 19-007, 2019; Institutional Security Policies and Crime Statistics, 2020). In order to be effective, primary prevention programs should be tailored to the community in which …

Due to the importance of improving both the teaching and learning of English as a Foreign Language (EFL) in Libya, the aim of this study is to understand EFL Libyan educators’ classroom instructional …

Epr Relaxation Of Modified Triphenylmethyl And Nitroxide Radicals, Whylder Moore

Electronic Theses and Dissertations

Trityl and nitroxide radicals are widely used as probes in chemical and biochemical systems. Understanding of factors that impact the electron spin relaxation for these radicals is important for selection of probes and experimental operating conditions. It has been previously reported that ¹³C isotope enrichment of the central carbon of the trityl yields a highly sensitive micro viscosity probe. It was important to characterize the impact of this substitution on the relaxation processes in fluid solution and immobilized samples.

Electron spin relaxation times for perdeuterated Finland trityl 99% enriched in ¹³C at the central carbon (¹³C …

“But I’M Not Racist”: How Implicit Racial Bias, Feedback And Racial Affective States Impact Clinical Judgment In Mental Health Treatment, Dhriti Tiwari

Electronic Theses and Dissertations

Implicit bias has gathered research interest in healthcare, yet remains less directly examined in the mental health field (Merino et al., 2018). Mental health providers can continue to be influenced by implicit bias despite higher ratings of cultural competence (Boysen, 2010). The purpose of this study was to supplement the limited research examining the impact of implicit bias on the clinical judgment process. The study aimed to examine whether: 1) implicit race bias scores were related to diagnostic impressions, 2) feedback about implicit bias was related to diagnostic impressions, and 3) racial affect mediated the relationship between receiving feedback and …

Evaluation Of The Effect Of The Clinical-Decision-Support Systems On Diabetes Management: A Multivariate Meta-Analysis Comparison With Univariate Meta-Analysis, Abdelfattah Elbarsha

Electronic Theses and Dissertations

The advantage of using meta-analysis lies in its ability in providing a quantitative summary of the findings from multiple studies. The aim of this dissertation was first to conduct a simulation study in order to understand what factors (sample size, between-study correlation, and percent of missing data) have a significant effect on meta-analysis estimates and whether using univariate or multivariate meta-analysis would produce different estimates.

The second goal of this study was to evaluate the effect of clinical decision support systems CDSS on diabetes care management by conducting three separate univariate meta-analyses and one multivariate meta-analysis. CDSS are health information …

Trainee Attitudes Toward Social Class As Predictors Of Clinical Decision Making: Exploring The Effects Of Classism In Psychotherapy, Jeremy J. Coleman

Electronic Theses and Dissertations

The current study examined the effects of classist beliefs on trainee attitudes toward their client based on perceived social-class status. This study sought to determine whether classist attitudes contribute to meaningful differences in clinical decision making. A sample of mental health trainees (n = 147) attending graduate-level programs in the U.S. were recruited and randomly assigned to one of two clinical vignette conditions. Both vignette conditions included identical data regarding a hypothetical client’s presenting concerns (e.g., sleep disturbance, worry, rumination, loneliness), but differed on indicators of client socioeconomic status (SES). Results showed statistically significant between-group differences on ratings of clinical …

Distributed Control, Optimization, And State Estimation For Renewable Power System, Qiao Li

Electronic Theses and Dissertations

The traditional power systems are usually centralized systems, in which the control, operation and monitoring are performed by the centralized control center, e.g., SCADA. However, with the development of renewable energy, power systems are getting more and more distributed. So, it becomes necessary to establish the distributed power system operation methods for these power systems. In this research, the distributed techniques for the renewable power systems are proposed based on the consensus protocol technique from graph theory. These techniques cover the three important problems in power systems, i.e., economic dispatch, state estimation, and optimal power flow. First, the Distributed Economic …

Maternal Hpa Axis Function During Parenting Is Associated With Reduced Brain Activation To Infant Cry And More Intrusive Parenting Behavior, Andrew Erhart

Electronic Theses and Dissertations

Previous research indicated that maternal cortisol function and maternal brain response to infant stimuli are separately related to differences in parenting behavior. Evidence from animal models have demonstrated that chronically high cortisol concentration alters brain structure and function, suggesting that studying these two mechanisms together may further improve understanding of parental behavior in human mothers. First time mothers of infants aged 1-7 months old (M age = 3 months) were recruited to participate. Mother’s cortisol concentration was measured during a naturalistic interaction with their infant and their behavior was coded for maternal sensitivity and nonintrusiveness. In a separate session using …

Supporting Ambitious Mathematics Practices In The Face Of School Reform: A Case Study Of High School Leadership, Jacklyn Van Ooyik

Electronic Theses and Dissertations

School leaders—both administrators and mathematics leaders—play a critical role in the instructional improvement of teachers in schools. However, current research in mathematics education has not provided a complete picture of the network of administrators, mathematics leaders, and teachers and their roles in supporting ambitious mathematics practices. The purpose of this case study is to examine how ambitious mathematics practices are developed, supported, and sustained within a high school facing pressures for test score improvement and graduation competencies and the roles and responsibilities of school leaders that contribute to that support. In order to address this issue, my primary research question …

Employee Ownership And Moral Hazard: How Broad-Based Equity Sharing Can Lower Agency Costs And Reduce Inequality, Colin Clinton Hudson

Electronic Theses and Dissertations

Providing incentives to top managers by offering equity has become the norm; this practice, however, does not hold for all levels of employees. After tax incentives for employee ownership were introduced through the Employee Retirement Income Security Act of 1974, there has been little legislative support to encourage companies to implement broad-based equity sharing programs. Moreover, decades of neoliberal policies have incentivized the pursuit of short-term profits and speculation, which contribute to economic instability and explain the growing gap between productivity and real wages observed since the late 1970s. Developments in the literature contend that employee ownership aligns the goals …

The Duality Of Reality: Perception Creation Using Symbolic Management, Christopher J. Thomas

Electronic Theses and Dissertations

People have historically used different types of symbols to signal an ideology, to create a sense of prestige, or to gain legitimacy. Examples of these types of symbols can be seen in displays ranging from marketing ads to presidential election materials. While these types of symbols tend to be socially constructed, and universally identifiable, the consequences of their use are less uniform in nature. This study explores the gap that currently exists between a symbol’s inherent value and the expected consequences of its use. My theoretical prediction includes two principles: The use of symbolic management to create symbolic environments and …

Change Request Prediction And Effort Estimation In An Evolving Software System, Lamees Abdullah Alhazzaa

Electronic Theses and Dissertations

Prediction of software defects has been the focus of many researchers in empirical software engineering and software maintenance because of its significance in providing quality estimates from the project management perspective for an evolving legacy system. Software Reliability Growth Models (SRGM) have been used to predict future defects in a software release. Modern software engineering databases contain Change Requests (CR), which include both defects and other maintenance requests. Our goal is to use defect prediction methods to help predict CRs in an evolving legacy system.

Limited research has been done in defect prediction using curve-fitting methods evolving software systems, with …

Ruptured Lives: Narrative Accounts Of Us American Adult Converts To Evangelical Christianity Over The Life Course, Nichole Baumer

Electronic Theses and Dissertations

Within the last few decades, there have been significant discussions regarding the rupturing effect that conversions to Christianity have in indigenous contexts. Individuals who have converted to Christianity from indigenous religions frequently speak of a disruption between their pre-conversion and post-conversion selves and social worlds. Anthropologists have yet, however, to study in-depth the narratives of people living within societies like the US, where Christianity is the hegemonic religion, to see whether or not the same phenomenon can be documented in contexts where individuals are often converting from one form of Christianity to another. Through the lens of narrative analysis, I …
