Stealth Dyslexia: Cognitive And Achievement Profiles Of Gifted Students With Dyslexia, Anne Hardy Boris

Dissertations

Identifying students who are gifted with dyslexia (GWD) has presented a host of challenges to practitioners in school and clinic settings because these individuals possess both qualities of giftedness and learning difficulties, yet do not ‘fit’ in either category. The term “stealth dyslexia” was coined to indicate the presence of high abilities that may mask dyslexia traits, complicate diagnostic accuracy, and allow individuals to compensate for their weaknesses. The masking of reading difficulties can cause dyslexia to remain undetected in gifted children for a prolonged period of time which may leave them prone to academic disengagement. The present study provided …

Relative Effects Of Self-Paced And Machine-Paced Learning Under Computer-Based Training, Eunju Choi

Dissertations

The purpose of this study was to compare the effects of a self-paced instruction versus machine-paced instruction using a computerized format. Instructional applications such as Programmed Instruction and Computer-Based Instruction have long touted the benefits of self-pacing (e.g., teaching machines, Personalized System of Instruction), but direct comparisons of different pacing types are lacking. Some preliminary research suggests that self-pacing may be prone to distraction by competing reinforcers and overall poor self-management of time. As such, it may be possible that machine-paced lessons (based on optimal timings) may foster better learning while retaining other beneficial features of CBI (interactivity, flexibility of …

Emotional Labor And New Independent School Heads, Seth William Yocum

Dissertations

The most important relationship to the life of an independent school has been the relationship between the head of school and the board of trustees. Still, most independent school heads have found that attending to their relationship with their board of trustees was one of the more challenging aspects of their work. Conventional wisdom and scholarship alike have suggested that this relationship could be especially trying for new independent school heads. The goal of this analytic autoethnographic study was to explore the performed emotional labor of new independent school heads in their relationship with their board of trustees during their …

Principals’ Definition And Identification Of Critical Thinking In Teacher Practices, Carmen Aumber Polka

Dissertations

Principals are teacher evaluators and, therefore, need a clear definition and identification of critical thinking in teacher practices to increase their impact on teacher effectiveness and student critical thinking outcomes. Beyond teacher evaluations, principals are responsible for supporting and developing teachers in their instructional practices (Davis et al., 2005) and for enhancing teachers’ pedagogical skills (Marzano et al., 2011). This instrumental case study explored how 12 principals, who use the Colorado State Model Evaluation System (CSMES) to evaluate critical thinking teacher practices, define critical thinking, and identify critical thinking utilized in teacher practices. Participants were purposefully selected from this Colorado …

Determining The Effectiveness Of Virtually-Delivered Written Exposure Therapy For Treatment Of Posttraumatic Stress Symptoms, Stephanie M. Haft

Dissertations

The COVID-19 pandemic has disproportionately impacted individuals with mental health issues (Swendsen, 2020). Although the peak destruction of the COVID-19 pandemic has passed, the psychological fallout remains. Social isolation, home confinement, and travel restrictions have exacerbated mental health issues during the COVID-19 pandemic, contributing to negative psychological distress (Smith et al., 2020). Survivors of trauma have higher vulnerability to prolonged psychological distress than the general population and others with non-trauma-related mental health conditions, which has been exacerbated during and following the COVID-19 pandemic. For these reasons, survivors of trauma may particularly benefit from virtual-delivery of trauma-focused treatments. Mental health providers …

Eleven participants who identified as Latinx child language brokers were interviewed. The purpose of this study was to explore the stories of these youth to better understand how they came to be language brokers in their families, their perspectives on their roles within their families and their culture, and the perceived positives and challenges of this practice. From these lived …

Time-Dependent Photoionization Modeling Of Warm Absorbers In Active Galactic Nuclei, Dev Raj Sadaula

Dissertations

Warm absorber spectra are bound-bound and bound-free absorption features, seen in the X-ray and UV spectra from many active galactic nuclei (AGN). The widths and centroid energies of these features indicate they occur in outflowing gas moving with hundreds to thousands of km/s. Depending upon the energy and momentum of the outflow, it can affect the gas within the host galaxy. Thus, warm absorbers’ mass and energy budgets are of great interest. Estimates for these properties depend on models that connect the absorption features' observed strengths with the density, composition, and ionization state of the absorbing gas. Such models assume …

Graduate Students' Self-Determination As Writers, Need For Cognition, And Sense Of Belonging As Predictors Of Confidence In Program Completion, Mary Ebejer

Dissertations

This study explored graduate student self-determination as a writer, need for cognition, and sense of belonging as predictors of their confidence today in their program completion. The data set consisted of 2,390 graduate students at universities across the United States. The data analysis was conducted using hierarchical linear modeling (HLM), with students nested in programs, nested in universities.

The analysis found that both self-determination as a writer and sense of belonging contributed to student confidence in program completion. Need for cognition did not. Seven statistically significant student-level demographic and program-related variables remained in the final model, including: PhD student, returning …

A Qualitative Case Study Of Health-Related Baccalaureate And Graduate Web-Based Simulated Clinical Learning Platforms, Kathrine Choura Branch

Dissertations

Simulation has been recognized as a teaching, learning, evaluation, and research strategy based on learning theories, that has come to play a significant role in healthcare education (Beal et al., 2017; La Cerra et al., 2019). Health-related academic programs in higher education have traditionally used simulation to fill gaps in learning and strengthen students’ clinical and critical thinking skills in conjunction with didactic classroom content, laboratory practice, and clinical education in the community setting (Hayden et al., 2014). With the onset and unpredictability of COVID-19, there was almost an immediate need for health-related academic programs across the world to transition …

Alternative Education Programs: An Exploration Of Programs And Supports To Reduce Juvenile Recidivism Among At-Risk Youth, Sarah Elizabeth Vanrensselaer

Dissertations

An exploration of alternative education programs and their relationship to juvenile recidivism was the focus of this narrative analysis. A constructivist epistemology and an interpretivist paradigm formed the conceptual framework, both of which aligned with the theoretical framework of Zimmerman’s (2008) self-regulated learning theory. The research questions focused on how alternative education programs impacted juvenile recidivism with a focus on 10 alternative education participants in Southeast, Wyoming, who have participated in the juvenile justice system. The use of multiple cases, coding, and collaboration between the researcher and the participants were used to ensure trustworthiness of this research. Results indicated the …

Enhancing Perspective-Taking Skills In Youth With Autism, Angelica Coumanova Kim

Dissertations

Individuals with Autism Spectrum Disorder (ASD) are known to have deficits in the areas of social interaction and social communication. One postulated explanation for the challenges seen in these areas is an underdevelopment of Theory of Mind (ToM). Research in the area of ToM and the mediation of perspective-taking interventions on social interactive and communicative skills has yielded a wide range of results and needs to be further explored. Thus, the present study aimed to contribute to the field of research by implementing a perspective-taking intervention with children who have ASD, with the goal of enhancing positive outcomes related to …

Self-Care, Anticipated Stigma, And Personal Therapy In Mental Health Professional Trainees, Morgan Condie

Dissertations

Self-care has increasingly become encouraged as a means for maintaining well-being for mental health professionals; yet, there exists an unsettling lack of research and guidance on this topic for those within the field (Callan et al., 2021; Colman et al., 2016; Norcross & VandenBos, 2018). This has led to call for change and reform to recognize the importance of self-care as an ethical imperative and to incorporate it within the education and training of mental health professionals (Barnett et al., 2007; Barnett & Cooper, 2009; Wise & Reuman, 2019; Zahniser et al., 2017). These calls for reform and the increased …

Mathematical Knowledge For Teaching In Co-Teachers At The Post-Secondary Level: A Cognitive And Enacted Approach, Lida Marie Lavelle Bentz

Dissertations

Mathematical Knowledge for Teaching (MKT), the knowledge used by a teacher to teach mathematics, has often been examined as a cognitive construct in K-6 teachers, but little research exists examining MKT in the post-secondary teaching context. Schoenfeld (2020) extended the definition of knowledge and thus MKT to include tacit and explicit perceptions. In doing so, Schoenfeld created the terms "big K" mKt and "little k" mkt, where mKt refers to the tacit and explicit perceptions used by a teacher to teach mathematics and mkt includes the teacher's understanding used in teaching mathematics (similar to cognitive MKT). Building from Schoenfeld’s conceptualization …

Masculinity Ideology As A Moderator On The Effects Of Lethal Means Counseling And Distribution Of Cable Locks On Firearm Storage Practices Among National Guard Personnel, Samantha E. Daruwala

Dissertations

Safer firearm storage practices, which may reduce suicide risk, can be promoted by lethal means counseling (LMC). A recent trial found that providing a single LMC session or distributing cable locks can lead to sustained changes in firearm storage practices within a sample of firearm-owning National Guard personnel (Anestis et al., 2021). An important next step is to consider if the intervention effects may differ based on participant characteristics. One particularly relevant sociodemographic characteristic to consider is traditional masculine norms, which are evident in the military and firearm cultures and associated with several negative outcomes. The current study evaluated if …

Implementation Planning To Increase Treatment Integrity For Check-In/Check-Out With An Electronic Dbrc, Caitlyn Weaver

Dissertations

The present investigation assessed the effectiveness of Implementation Planning (IP) as a strategy for improving the treatment integrity of a commonly implemented behavioral intervention, Check-In/Check-Out (CICO). An electronic daily behavior report card (E-DBRC) was used to monitor intervention effectiveness for three students across a non-concurrent multiple-baseline design. IP was not associated with consistent improvements in treatment integrity for teachers who served as mentors within the CICO intervention. Teacher treatment integrity improved for one student’s teacher but had no sustained functional relation for the other two teachers. Student behavioral data were collected to determine if the implementation of CICO was associated …

Examining P3 And N2 Amplitudes Following Social Exclusion And Provocation In College Students With High And Low Narcissistic Traits, Kathleen Ramsey

Dissertations

Adults with narcissistic traits are prone to reacting aggressively following provocation due to elevations in emotional reactivity and perceived threat to their grandiose self-views. Prior studies have examined event-related potentials (ERPs) measures in college students with narcissistic traits in the context of risky decision making and facial emotion processing; however, no known studies have examined how those with narcissistic traits react to rejection and provocation at the neurophysiological level during an externally valid social rejection task (i.e., Cyberball). For the purposes of this study, it was predicted that participants with higher levels of narcissistic traits (both total narcissism and grandiose …

Using Nudges To Increase Engagement With Suicide Prevention Resources In An Online Sample Of United State Military Veterans, Brian W. Bauer

Dissertations

Suicide rates have continually increased from 1999 to 2019 in the United States, with populations such as military Veterans showing substantially higher suicide death and attempt rates than civilians. Behavioral economics researchers have demonstrated that people regularly make decisions that are not aligned with their own self-interests (i.e., irrational decisions). These irrational decisions often stem from humans having bounded rationality (i.e., limited computational power), which produce reliable cognitive biases that occur outside of people’s awareness and influence the decisions they make. There are many important decisions leading up to a suicide attempt (e.g., whether to engage with suicide prevention resources), …

Exploring The Impact Of Simulation Anxiety On Clinical Judgment For Nursing Students, Janet M. Reed

The Effect Of Implementing A Cultural Change Toolkit On Burnout Among Emergency Nurses, Isabella Nassif

Dissertations

Burnout continues to be a significant problem that negatively affects healthcare providers, especially nursing staff in acute care settings, such as the emergency department. Burnout is the state and experience of continued and prolonged exposure to depersonalization, loss of motivation, emotional exhaustion, and reduced personal accomplishment (Harris & Griffin, 2015; Hutson Hendy, 2016). Burnout is manifested through depersonalization, having a loss of compassion and concern, a decreased sense of personal accomplishment from work, and emotional exhaustion from feeling emotionally drained (Li et al., 2018). The literature on burnout lacks a systemic analysis of evidence-based interventions that can mitigate burnout among …

Designing Dynamic And Degradable Polymeric Materials With Thiol-X Chemistries, Reese Sloan

Dissertations

With plastic production poised to increase in coming years, there arises a need to develop new polymeric materials designed to combat the global pollution crisis. A commonly utilized approach in addressing this challenge is to employ a responsive functional moiety into the polymer architecture. Thiol-X reactions, a commonly utilized class of “click” reactions, have garnered broad implementation in new stimuli-responsive materials. This work specifically focuses on utilizing radical-mediated thiol-ene coupling and base-catalyzed thiol-isocyanate reactions to develop a library of ternary thiol-ene/thiourethane covalent adaptable networks (CANs) and hydrolytically labile poly(thioether ketal) thermoplastics. CANs are a class of network materials capable of …

An Exploratory Multiple Case Study Of Discipline Practices In A Major Metropolitan Public School District: A Look Into The School To Prison Pipeline, Neil French, Kristin Calvert-French, Phyllis Jackson, Erin King

Dissertations

The school to prison pipeline is a phenomenon fed by exclusionary discipline practices that increase the likelihood that a student will have an interaction with the juvenile or criminal justice system at some time in their life; this phenomenon disproportionately affects Black students. Understanding the problem is key to slowing down the school to prison pipeline. This study of a school district in Missouri explores questions about how interpersonal relationships, implicit bias awareness, and school policies influence the learning environment, and how those factors relate to school discipline, which ultimately can lead to the school to prison pipeline.

Relationship Of Leader-Member Exchange On Role Stress And Burnout: A Public Accounting Perspective, Sammie Parsley

Dissertations

An issue that concerns public accounting firms, both large and small, is that of employee burnout within the workplace. As a service-oriented industry, accommodating client needs is pivotal to long-term success. With that in mind, meeting client demands often means accountants must work long and strenuous hours, an attribute inherent to the industry. Consequently, public accounting firms often find themselves struggling with voluntary turnover as a result of burnout and opportunity for increased financial incentives elsewhere. The busy season in public accounting can be especially difficult, as accountants can find themselves working very long hours for weeks on end. This …

Resilience In Black Mental Health Counselors, Ericka Cables

Dissertations

Though resilience is a commonly studied variable in different disciplines, there is relatively little research on occupational settings. Researchers take various perspectives in defining resilience as a trait, process, and an outcome. Regardless of how it is defined, it is a vital protective factor for Black mental health counselors who may be significantly impacted by similar experiences, such as racism and racial discrimination, as the Black clients they serve. This dissertation study consisted of two studies utilizing the same data set. In the first study, psychometric properties of a new quantitative instrument, the Race-Based Resilience Scale (RBRS), was constructed to …

Long-Term English Learners In Middle School: Perspectives On Growth In Language Acquisition And Academic Learning, Barbara Doerfler

Dissertations

Middle schools in the United States today have a large population of English learners (ELs), and many of them have been educationally labeled as long-term English learners (LTELs). In some middle schools, over half of the ELs in seventh and eighth grades meet the criteria for classification as LTELs. This is especially concerning as these students will shortly be moving on to high school with limited English proficiency, which will continue to affect their academic performance and may limit their choices in higher education and career paths. This study explored the educational experience of LTELs in middle school by seeking …
