The Mathematics Achievement Gap In Virtual Education, Sara Glover

Electronic Theses and Dissertations

This phenomenological study examined the lived experiences of online Algebra I teachers as they relate to the instruction of minority students. There is an academic achievement gap that exists between minority students and their non-minority peers in United States public education (Sousa & Armor, 2016). Although national educational policy has sought to narrow the academic achievement gap, it is persistent and must be addressed because public education affects the future of our nation (Fullan & Quinn, 2016). Virtual education is a growing platform for learning, with nearly 300,000 students enrolled across the United States. Achievement data demonstrates the existence of …

Noninvasive Myographical Assessments Following Unaccustomed Resistance Exercise, Carleigh Boone

Electronic Theses and Dissertations

Traditionally, post-exercise muscular alterations have been examined using invasive techniques that lack the ability to single out individual muscle groups. Sonomyography, tensiomyography, and electrical impedance myography allow for noninvasive skeletal muscle assessment. This project aimed to examine changes in muscle contractility and composition that occur in the early stages of recovery following unaccustomed exercise. METHODS: Twenty-one untrained adults (21.9 ± 1.9 y) performed exercise – 10 × 10 maximal eccentric knee extensions – with their nondominant leg. For each repetition, participants moved through 90° range of motion at 90°•s-1 with a passive return to the start position. Each set was …

Effects Of Rest Position On Ultrasound-Derived Morphological Characteristics Of The Vastus Lateralis And Lower-Body Force Production, Alyssa Varanoske

Electronic Theses and Dissertations

INTRODUCTION: Ultrasound assessment of the lower body typically encompasses 10-15 minutes of supine rest prior to examination because of the potential influence of gravitational fluid shifts on tissue size and composition. However, examination of the vastus lateralis (VL) muscle requires individuals to lay in the lateral recumbent position, and this change in position may influence muscle morphological characteristics and their ability to predict muscle function. PURPOSE: The purpose of this investigation was to examine the effect of rest position on ultrasound-derived morphological characteristics of the VL and to determine whether or not rest position affects the relationships between muscle morphological …

Gamification: Badges And Feedback, Brian Macon

Electronic Theses and Dissertations

Gamification, the implementation of game elements in a non-game context, is a rapidly growing field of research. One element of gamification that has experienced a rapid growth in popularity is the use of digital badges. Despite widespread adoption in educational settings, there are still gaps in the understanding of their effects on motivation, engagement, learning, and other factors. Furthermore, feedback delivered through badges can include a symbolic reward for successful completion of a task, providing a credential for gaining a skill, or acknowledging mastery of a particular piece of knowledge. This study implemented digital badges in online courses at a …

Detection Of Mercury Through Surface Plasmon Resonance Of Immobilized Gold Nanorods, Khang Trieu

Electronic Theses and Dissertations

Mercury is a known environmental pollutant that can damage the brain, heart, kidney and lungs upon exposure. Emissions from fossil fuel plants can release mercury into the air, where it can settle into the water supply and be exposed to human and aquatic life. The use of gold nanorods functionalized on solid substrates as a mercury sensor in tap water samples is investigated herein. The functionalization of the substrates involves the physical immobilization of the nanorods onto the solid surface through the use of (3-mercaptopropyl)trimethoxysilane (MPTMS). The immobilization of the nanorods drastically increases their stability, allowing for use in complicated …

However, residents of the Keowee and Jocassee valleys had to be removed, a process that started years earlier when Duke Power began serious land purchasing efforts. This study focused on discovering diverse narratives from people that …

Role Of Atm In T Cell Dysfunction During Chronic Viral Infections, Juan Zhao

Electronic Theses and Dissertations

Hepatitis C virus (HCV) or human immunodeficiency virus (HIV) infection leads to a phenomenon of inflammaging, in which chronic infection or inflammation induces an immune aged phenotype with T cell dysfunction. Thus, HCV or HIV infection has been deemed as a model to study the mechanisms of T cell infammaging and viral persistence in humans. In this dissertation, T cell homeostasis, DNA damage and repair machineries were investigated in patients with chronic HCV or HIV infection at risk for inflammaging. We found a significant depletion in CD4 T cells, which was correlated with their apoptosis in chronically HCV/HIVinfected patients, compared …

Successful Factors For Native And Community College Transfer Students In Engineering Technology At A Four-Year University, Leendert Craig

Tennessee has 2 programs: the Tennessee Promise and the Tennessee Reconnect programs that offer students tuition-free access to the state’s community college system. Previous studies have been conducted to compare transfer students’ performances to that of native students and typically compared the students in all disciplines. This study seeks to compare transfer students (students who enter the participating university with 40 or more credit hours) to native students (students who initially enrolled or transferred into the 4-year …

Adverse Childhood Experiences, Homeless Chronicity, And Age At Onset Of Homelessness, Joseph T. Tucciarone Jr.

Electronic Theses and Dissertations

Childhood adversity is associated with numerous negative outcomes across multiple domains, including mental and physical health, interrelationships, and social functioning. Notably, research suggests that childhood adversity has a dose-response relationship with these outcomes; that is, greater numbers of adverse experiences in childhood are associated with worse outcomes. These outcomes overlap with many risk factors of homelessness. This study sought to address two questions: 1) Does a dose-response relationship exist between childhood adversity and chronic homelessness? 2) Does childhood adversity negatively predict the age at which homelessness first occurs? Adults experiencing homeless who are accessing homeless services in the Tri-Cities area …

Religious Attendance, Surrender To God, And Suicide Risk: Mediating Pathways Of Feeling Forgiven By God And Psychopathology, Kelley Pugh

Electronic Theses and Dissertations

Suicide is a national public health concern, and college students may be at increased risk. Symptoms of psychopathology (i.e., stress, anxiety, and depression) may contribute to risk, whereas religiosity (i.e., religious attendance, surrendering to God, and feeling forgiven by God) may reduce risk. Students from a rural southeastern university (N=249) completed self-report measures. Serial mediation analyses indicate that attendance and surrender to God are inversely- predictive of suicide risk, both directly and through the indirect pathways of feeling forgiven by God (1st order mediator) and psychopathology (2nd order mediators). In all models, specific indirect effects occurred through feeling forgiven by …

An Investigation Into The Structure Of Self-Control, Parker A. Dreves

Electronic Theses and Dissertations

Self-control has been measured using a variety of methods including self-report measures, cognitive inhibition tasks, delay discounting and delay of gratification tasks, and persistence and willpower tasks. Although these are all theoretically linked to processes involved in self-control, recent evidence has shown that these diverse measurement techniques relate only minimally to one another. Assuming that self-control is a reflective construct, this would indicate that many of these tasks are poor indicators of self-control. The present research challenges the common assumption that self-control is a reflective construct and instead proposes that self-control is a formative construct. Conceptualizing self-control as a formative …

Telomeric Dna Damage And Repair Machineries In Hiv Infection, Lam Nguyen

Electronic Theses and Dissertations

In this thesis, we investigated T cell homeostasis and DNA damage repair machineries in HIV infection. We found that the frequencies of CD4T cells were low, which is associated with cell apoptosis in HIV patients compared to healthy subjects. Importantly, these events were closely correlated to the increase in T cell exhaustion, senescence, DNA damage, and telomere attrition. Mechanistically, while the DNA damage sensors Mer11, Rad50, and NBS1 (MRN) complexes remained intact, the ataxia-telangiectasia mutated (ATM) kinase and its downstream checkpoint kinase 2 (CHK2) were significantly inhibited during HIV infection. Additionally, telomeric repeat-binding factor 2 (TRF2) that functions to protect …

Religiosity, Parental Support, And Formal Volunteering Among Teenagers, Isaac Paintsil

Electronic Theses and Dissertations

Few countries can boast of having the culture of formal volunteering seen in the United States. In explaining this phenomenon, many empirical studies have found religiosity significant in predicting behaviors among young adults, adults, and the elderly. However, teens (13 – 17 years) have not attracted much attention from researchers, though they possess the time and resources most needed to volunteer. Using data from the National Study on Youth and Religion (NSYR) Wave 1, this study examines the relationship between formal volunteering and teens’ individual (religious salience and religious experience) and collective religiosity (religious tradition, church attendance, and religious youth …

The Effects Of Two Novel Anti-Inflammatory Compounds On Prepulse Inhibition And Neural Microglia Cell Activation In A Rodent Model Of Schizophrenia, Heath W. Shelton

Electronic Theses and Dissertations

Recent studies have shown elevated neuroinflammation in a large subset of individuals diagnosed with schizophrenia. A pro-inflammatory cytokine, tumor necrosis factor-alpha (TNFα), has been directly linked to this neuroinflammation. This study examined the effects of two TNFα modulators (PD2024 and PD340) produced by our collaborators at P2D Bioscience, Inc., to alleviate auditory sensorimotor gating deficits and reduce microglial cell activation present in the polyinosinic:polycytidylic (Poly I:C) rodent model of schizophrenia. Auditory sensorimotor gating was assessed using prepulse inhibition and microglial activation was examined and quantified using immunohistochemistry and confocal microscopy, respectively. Both PD2024 and PD340 alleviated auditory sensorimotor gating deficits …

Evolving Mediums: Over The Garden Wall And The Divine Comedy, Karissa Doughty

Electronic Theses and Dissertations

Dante Alighieri’s transcendental work the Divine Comedy is masterfully appropriated in this cartoon mini-series titled Over the Garden Wall in order to explore the issue of suicidal ideation and depression while contradicting Dante. Through different textual and conceptual appropriations, the show invokes the imagery of the Divine Comedy while creating an ending that is the complete opposite of its source text, turning Dante on his head and becoming an anti-Divine Comedy. The different characters of the epic poem are reimagined for these purposes, and the result is a work of art that makes the personal into the universal.

Teacher’S Attitudes And Willingness To Refer Sexual Minority Students To Special Education, Diane' Forney

Electronic Theses and Dissertations

Research shows that cultural minority students are over-represented in special education services based on teacher bias and attitudes towards these cultural minority students. A cultural minority that has not been as widely researched is the Lesbian, Gay, Bisexual, Transgender, and Questioning (LGBTQ). The purpose of this study is to determine if teacher’s bias and attitude towards LGBTQ students interferes with their ability to make special education referrals for sexual minority students (Hebl, 2000), who are students identified as LGBTQ. For the purpose of this study, a variety of teachers were asked to complete, two qualifying questions, a detailed demographic questionnaire, …

Risk-Taking, Thinking Styles, And Criminality: A Fuzzy-Trace Theory Perspective, Adrienne Machann

Electronic Theses and Dissertations

Preferred modes of thinking, otherwise known as biases, have been well documented in adult reasoning and decision-making (Evans, 2003; Gilovich, Griffin, & Kahneman, 2002; Reyna & Brainerd, 2011; Tversky & Kahneman, 1986). Researchers have explained these biases by proposing that the basis for them is a system of thought that relies mostly on intuition and “gut feelings” rather than logical analysis of the situation (Reyna & Brainerd, 2011; Tversky & Kahneman, 1986). According to standard dual-process theories, intuition is described as a thought process so quick, it is automatic and, at times unconscious; conversely, analytical thinking is slow and steady, …
