A mixed-method approach using a sequential explanatory design was used to first gather quantitative information concerning student perception and use of office hour within online classes and student interaction preferences within online classes. This information was then used to in the development of a framework base the ARCS Model of Motivational Design and Social Information Processing Theory for instructors to use when planning and implementing …

This Was The World And I Was King: Land And Identity In Scottish Children's Literature Of The Golden Age, Rodney Fierce

Dissertations

This dissertation focuses on Scottish cultural identity and its erasure in nineteenth-century British children’s literature as successful Scottish authors became known as British authors, and British children’s literature was canonized as the genre’s first Golden Age. Specifically, it explores the ways that Catherine Sinclair, George MacDonald, R. M. Ballantyne, Robert Louis Stevenson, J. M. Barrie, and Helen Bannerman—six popular nineteenth-century Scottish authors—maintain a sense of Scottishness in their adventure fiction. By reading the texts in the historical context of the authors’ biographies, I demonstrate that the land in their works and the benevolent colonizers allowed to control it in some …

Mobbing And Job Satisfaction Among Registered Nurses In Mississippi, Brenda Collins

Dissertations

The incidences of mobbing or workplace bullying are a common occurrence among nurses. The practice has been associated with overwhelming and long-standing comprising emotional, psychosomatic, and psychosocial distress. Mobbing (workplace bullying) impacts the target, those close to them, and the organization in which they work. The experience of mobbing produces affective reactions in the target. Affective experiences on the job can impact job satisfaction within organizations. Job satisfaction plays an essential role in sustaining an adequate nursing workforce. Subsequently, some nurses become frustrated and opt for resigning or early retirement when they are no longer satisfied with the culture or …

When You Play The Game Of Drones, You Win Or You Die: Examining The Role Of U.S. Drone Strikes In U.S. And English Language Allies Newspapers From 2008-2019, Melissa Aho

Dissertations

In the years following the terrorist attacks on September 11, 2001, the United States ramped up its usage of drones and drone strikes around the world. Spanning three United States’ presidents, drone strikes became a regular feature in the US military arsenal. While American newspaper media and citizens have been very pro-drone, global citizens view drones in a far more negative light. This study examines US military drone strikes and English-speaking allied newspapers in Australia, Canada, New Zealand, and the United Kingdom and evaluates if coverage remains positive or negative depending on the newspaper’s conservative or liberal leanings from 2008–2019. …

Framing Difference: A Content Analysis Of Disability Coverage In Saudi Arabia Newspapers, Majedah Alsewaiah

Dissertations

The problem of misrepresentation and underrepresentation of people with disabilities in printed periodical media raises concerns for stakeholders. Although this problem extends to multiple global cultures, the invisibility of people with disabilities in Saudi Arabia newspapers is particularly concerning. The existence of negative stereotypes that prevent individuals with disabilities from achieving positive progress in their lives is perpetuated by negative frames that the media fosters in its flawed narratives of disability.

The application of the framing theory enables the current study to expand the knowledge of positive and negative frames that exert an influence on stakeholders. Based on the literature …

Physical Education Teachers' Instructional Adaptations To Teach Motor Skills To Children With Language Disorders, Kristen Morgan

Dissertations

Children with language disorders have a unique blend of impairments related to communication, memory (Gray et al., 2019; Montgomery et al., 2019), executive functioning (Kapa & Plante, 2015), motor skills (Hill, 2001), imitation, gestures (Wray et al., 2017), and reaching early motor milestones (Diepeveen et al., 2018). These deficits may negatively affect learning motor skills in physical education (PE). Instructional adaptations to overcome these learning impairments in PE has not been greatly explored in the literature. Nor has teachers’ level of self-efficacy in providing adaptations to children with language disorders. The purpose of this study was to examine instructional adaptations …

Interleukin-17a Facilitates Chikungunya Virus Infection By Inhibiting Ifn-Α2 Expression, Biswas Neupane

Dissertations

Interferons (IFNs) are the key components of innate immunity and are crucial for host defense against viral infections. Here, we report a novel role of interleukin-17A (IL-17A) in inhibiting IFN-α2 expression, thus promoting chikungunya virus (CHIKV) infection. CHIKV infected IL-17A deficient (Il17a^-/-) mice expressed a higher level of IFN-α2 and developed diminished viremia and milder footpad swelling in comparison to wild-type (WT) control mice, this was also recapitulated in IL-17A receptor-deficient (Il17ra^-/-) mice. Interestingly, IL-17A selectively blocked IFN-α2 production during CHIKV, but not West Nile virus (WNV) or Zika virus (ZIKV), infections. Recombinant IL-17A …

"Ain’T I A Woman?”: The Intersectional Representation Of Black Women Professional Leaders Above The Concrete Ceiling In Scandal And How To Get Away With Murder, Jessica Love

Dissertations

This dissertation investigates the politics of re-presentation of the two Black leading characters in Shonda Rhimes’s televised series, Scandal (Olivia Pope) and How to Get Away with Murder (Annalise Keating). This textual analysis explores how the characters are re-represented as leaders at the intersections of race, class, gender, and sexuality using Kimberlé Crenshaw’s (1989) theory of intersectionality. This study also imposes Patricia Hill Collins’s (2005) matrix of domination to explicate how the hegemonic structure of the concrete ceiling conditions their identities and exertion of power in the workplace. To do this, the researcher investigated cultural workplace expectations tied to notions …

Photopolymer Networks With Tunable Command Destruct Properties, William Walker

Dissertations

Photoinduced thiol-catalyzed hydrogen abstraction and beta-scission of acyclic benzylidene acetals is demonstrated as a new route to “command-destruct” polymer thermosets. Using this approach, we show that poly(thioether acetal) networks synthesized via thiol-ene photopolymerization rapidly degrade to alkyl benzoate byproducts when triggered with light, transitioning from solid to liquid within seconds. The light-driven construction and destruction processes, accessible via distinct differences in kinetics, are readily amendable for photopatterning, additive/subtractive manufacturing, and wavelength-selective applications.

The first chapter of this dissertation details the development of command-destruct poly(thioether acetal) networks via a previously unexplored mechanism for polymer degradation. The degradation mechanism is confirmed via …

The Role Of The Msaabcr Operon In Cell Wall Integrity And Programmed Cell Death During Biofilm Development, Bibek G C

Dissertations

Staphylococcus aureus is an important human pathogen in both community and health care settings. Biggest challenges with S. aureus as a pathogen is its ability to acquire antibiotic resistance and produce robust biofilms. In this work, we investigated the nature of the cell wall defect in the msaABCR operon mutant in the Mu50 (VISA) and USA300 LAC methicillin-resistant Staphylococcus aureus (MRSA) strains. Results showed that msaABCR-mutant cells had decreased cell wall thickness and cell wall crosslinking in both strains. These defects are most likely due to increased murein hydrolase activity and/or nonspecific processing of murein hydrolases mediated by increased …

Gender And Cross-Cultural Invariance Of Attitudes Toward Statistics Among Non-Stem Undergraduate Students, Mihili Edirisooriya

Dissertations

Because of the wide usage of statistics in almost every field, many universities have incorporated statistics into their undergraduate and graduate curricula. Students taking statistics have often reported negative experiences and an aversion to statistics. Non-STEM students have often reported negative attitudes toward statistics (Chew & Dillon, 2014; Keeley et al., 2008). Researchers have used qualitative and quantitative approaches to measure attitudes toward statistics. The Survey of Attitudes Toward Statistics-36 (SATS-36) scale has been the most widely accepted measure to investigate attitudes toward statistics. Any psychometrically sound measurement instrument requires invariance across groups in its usage. Otherwise, measurement biases could …

Discrete Moving Target Defense Application And Benchmarking In Software-Defined Networking, Charan Gudla

Dissertations

Moving Target Defense is a technique focused on disrupting certain phases of a cyber-attack. The static nature of the existing networks gives the adversaries an adequate amount of time to gather enough data concerning the target and succeed in mounting an attack. The random host address mutation is a well-known MTD technique that hides the actual IP address from external scanners. When the host establishes a session of transmitting or receiving data, due to mutation interval, the session is interrupted, leading to the host’s unavailability. Moving the network configuration creates overhead on the controller and additional switching costs resulting in …

Honor And Duty: The Collegiate Education Of A Yeoman Farmer’S Son In Antebellum Mississippi, David Taylor

Dissertations

This endeavor reviews the mindsets and ideologies emerging from the South in the era known as "King Cotton," a time which predated the American Civil War and in which cotton was the primary export of the South. It is historically relevant to Higher Education in that it views this mindset through the eyes of young, white, single males and in particular, one male, a student of Mississippi College in Clinton, Mississippi. This description will focus on the years from 1850 to 1860 and this male population. This in no way degrades or neglects the contribution or inclusion of women in …

All Means All: Exploring Co-Teaching Dyads Working With Students With Significant Support Needs, Katrine Sophie Meyers Breien Gosselin

Dissertations

Co-teaching is a framework that teachers utilize to support one another and actively include students with diverse learning needs. However, it is not frequent that special education and general education teachers use co-teaching to provide meaningful inclusion for students with significant support needs (SSN). This qualitative study explored effective general and special education co-teaching dyads who worked with students with SSN within the general education classroom. Participants included six teachers (three general education and three special education) who participated in semi-structure and dialogical interviews, virtual and verbal classroom walks, and provided artifacts and reflections. Interviews with participants were conducted separately …

Estimating School-Level Effects Of Mandatory Student Grade Retention Policies Using Latent Growth Curve Modeling, Matthew Koziol

Dissertations

Mandatory grade retention for poor-performing readers has been a disputed practice for decades. Since the early-2000s, state-level mandatory grade retention policies have proliferated. In 18 states and Washington, D.C. mandatory grade retention exists for students in the third grade who fail an end-of-year standardized reading exam. These policies are based on research that suggests students who do not read by the third-grade are at much greater risk of dropping out of school prior to receiving a high-school degree. Mandatory grade retention policies use a gatekeeper mechanism at the end of the third grade to ensure that students who are not …

Action And Outcome: The Connection Between Organizational Goals And Organizational Effectiveness In Major League Baseball, Brian Joseph Fowler

Dissertations

Major League Baseball (MLB) provides an optimal setting to investigate the effects of specific strategic organizational goals and decisions on various key performance indicators (KPIs). The choice to primarily pursue wins or profits (i.e., win maximization or profit maximization), along with how efficiently organizations spend their budgets (i.e., utility), have been shown to impact competitive balance, social welfare, and ticket pricing of sports leagues. The present research builds on the work of previous scholars by empirically examining MLB organizational management at the individual team level. Data collected for the current research included financial information and organizational KPIs for all 30 …

Career Development In Sport And Leisure: An Application Of Social Cognitive Career Theory, Nicole Sellars

Dissertations

Utilizing Social Cognitive Career Theory (Lent et al., 1994) this research aimed to determine perception differences related to sport and leisure management employment for undergraduate students in related degree programs with a specific focus on the minority groups of women and People of Color (POC). Given the lack of diversity in sport and leisure enrollment and employment (Adriaanse, 2016; Massengale & Lough, 2013; Shropshire, 2004; Vianden & Gregg, 2017), this research sought to explore whether gender and/or race were predictors of feelings of self-efficacy, outcome expectations, barriers, and supports. An electronic survey was distributed to sport and leisure management undergraduate …

Understanding Potential Climate Change Impacts On Water Resources Within A Fractured Rock Watershed In Northern Togo, Mahawa-Essa Mabossani Akara

Dissertations

More than 72% of sub-Saharan Africa land surface is comprised of hard rock with fractured rock aquifers supplying water to an estimated 25% of the rural population. Given low porosity and storativity, fractured rock aquifers are particularly vulnerable to stresses such as projected population growth and climate variability. General circulation models of sub-Saharan Africa predict increases in temperature and in occurrences of extreme precipitation trends, such as flooding and drought. Adaptation strategies that promote optimal uses of water resources have emerged, although, most focus exclusively on surface water resources. This project investigates the potential impact of climate change on surface …

Cities Leading The Way: Municipal Climate Policy In The Us, Naomi Bick

Dissertations

Understanding cities is a key feature for understanding responses (or lack thereof) to a collective action problem like climate change. In the absence of federal climate change policies in the United States, many city and state governments have adopted and implemented policies to mitigate and adapt to climate change. As mayors, city managers, and city councils increasingly become central actors, scholars have shifted their studies to focus on city climate change policy (Yi et al. 2017a, Hughes 2017). Descriptive case studies have identified a broad range of factors; however, the causal mechanisms of whether cities adopt and implement climate change …

The Impacts Of Aging, Sedentarism, And Exercise On Neurotrophic Factor Expression And Innervation In The Heart And The Effects Of Treatment With Α-Cgrp On Heart Function, Gabriel Almeida Alves

Dissertations

Neurotrophic factors (NFs) are important molecules responsible for development, differentiation, regeneration, and maintenance of new and mature neurons. Neurotrophic factors act as neurocytokines and may assist with the regulation of axonal and dendritic arrangements and synaptic plasticity between neurons themselves or with other non-neural target tissues. In this study, we analyze the levels of two NFs: glial cell line-derived neurotrophic factor (GDNF) and nerve growth factor (NGF). Cardiomyocytes produce these neurotrophic factors which assist with the innervation pattern of the heart. The heart is innervated by the two branches of the autonomic nervous system; namely the sympathetic nervous system and …

Compassion For Self-Identity: An Evaluation Of A Compassion-Based Intervention For Stigmatized Sexual Identities, Du T. Nguyen

Dissertations

Sexual minority persons often experience notable negative mental and physical health disparities when compared to their heterosexual counterparts. According to the minority stress framework, it is posited that these discrepancies are due to additional, group-specific stressors that they experience beyond stress felt by the general population. One such minority stress variable that has received considerable attention is sexual stigma. Not only has sexual stigmatization been found to be related to negative mental and physical health outcomes, it has also previously been found to hinder adaptive emotion regulation.

Due to the minority stress felt by sexual minority persons, there is a …

Investigating The Relationship Between Departmental Support Structures, Self-Efficacy And Intention To Persist: An Examination Of Students' Experience In 19 Physics Graduate Programs Across The United States, Diana Sachmpazidi

Dissertations

Science, Technology, Engineering, and Mathematics (STEM) graduate programs experience consistently high attrition rates. Moreover, persistent disparities exist in racial and gender representation. Women and People of Color are significantly underrepresented and have higher attrition rates than men and white and Asian American students. To date, little work is done to understand graduate student attrition or persistence. There is also a lack of information regarding the causes of demographic disparities in attrition. Most past studies in this context have focused on students' attributes, undergraduate preparation, and mentoring relationships. Moreover, student self-efficacy is a contributing factor for undergraduate student retention. Yet, there …

Nurse-Midwifery Student Self-Confidence And Anxiety When Using Objective Structured Clinical Examinations As A Clinical Competency Assessment Strategy, Deborah Anne Duran-Snell

Dissertations

Current evaluation of clinical competency in nurse-midwifery education programs lacks clarity and consistency and is often a subjective process using a variety of assessment strategies. Recognizing that no single assessment strategy can provide all the information required to assess something as complex as clinical performance, the objective structured clinical examination (OSCE), when viewed alongside other forms of assessment, might be considered a valuable strategy for enhancing the assessment of nurse-midwifery student clinical competence and confidence. The main objective of this dissertation was to assess and compare self-reported confidence and anxiety levels of graduate nurse-midwifery students pre- and post-OSCE. This exploratory …

Transdiagnostic Classification Of Behavior In Childhood: Profile Analysis And Interrater Stability, Gary Rempe

Dissertations

There is growing concern among both researchers and practitioners that mainstream psychopathological classification schemes inadequately meet the needs of individuals seeking treatment for mental illness. Recent efforts in childhood psychopathology have sought to derive new diagnostic subgroups that are less susceptible to the heterogeneity and comorbidity issues that have been reported with categories specified in more recent versions of the diagnostic and statistical manual of mental illness. These transdiagnostic subgroups are generated by using unsupervised machine-learning algorithms that separate cases into homogenous groups with information from multiple continuous indicators. This dissertation seeks to expand on this work by exploring natural …

Salary Discrimination In The Sports Labor Market: An Evidence From Major League Soccer, Hoyoon Jung

Dissertations

Since Gary Becker’s (1971) discrimination theory, which provided the groundwork to investigate various forms of discrimination based on individuals’ demographic characteristics, wage discrimination has been a long-standing issue in labor economics and sport management. With this knowledge, it is of interest to examine whether sports labor markets offer equal financial opportunities. Although a growing body of literature has examined and uncovered evidence of pay discrimination in various sports settings, relatively little attention has been paid to Major League Soccer (MLS) because of its short history. In addition, there is a need to understand salary discrimination among superstars in MLS amid …

Anxiety, Depression, And Perceived Barriers To Adherence Among Parents Of Pediatric Transplant Patients, Alice Marie Wille

Dissertations

Before being listed for an organ transplant, pediatric patients and families undergo a psychosocial pre-transplant evaluation to determine familial strengths and risk factors that may impact the success of transplant. Adherence is considered to be one of the primary factors in the survival of the transplanted organ and existing research has suggested a link between parental functioning and post-transplant adherence. To better understand the relationship between parental mental health and perceived barriers to adherence, this study examined whether parental symptoms of anxiety and depression significantly predicted parent and patient perceived barriers to adherence in the pre-transplant phase (n=65 parents and …
