The Rebel Made Me Do It: Mascots, Race, And The Lost Cause, Patrick Smith Apr 2019

The Rebel Made Me Do It: Mascots, Race, And The Lost Cause, Patrick Smith

Dissertations

Public memory is commonly tied to street names, toponyms, and monuments because they are interacted with daily and are often directly associated with race, class, and regimes of power. Mascots are not thought of in the same manner although they are present as part of everyday life. The childish or sometimes comedic nature of the mascot discounts it from many considerations of its influence, symbolism and history. Nonetheless this research focuses on the term “Rebel” as a secondary school mascot. The term possesses the trappings of race because the American vernacular ties the word to the Confederate States of America …


Network Equivalents Applied To Transient Analysis Of Large Distribution Systems, Ghassan Abdul-Hussein Bilal Apr 2019

Network Equivalents Applied To Transient Analysis Of Large Distribution Systems, Ghassan Abdul-Hussein Bilal

Dissertations

Frequency domain (FD) methods for electromagnetic transient analysis of electric power systems offer outstanding simplicity and accuracy when dealing with distributed parameter elements and components that exhibit frequency-dependent behavior. However, the use of FD methods is usually restricted to the simulation of small and simple networks, since it is commonly believed that their application implies a very large computational burden when compared to time domain methods. This study demonstrates that FD methods can accommodate the detailed simulation of large distribution networks within acceptable computer times and in a very straightforward manner, thus offering an attractive complement or alternative to common …

A Pilot Study: Identifying The Characteristics Of Postsecondary Offices Of Disability Services Associated With High Graduation Rates, Tiffany B. White

Dissertations

Students with disabilities are entering postsecondary education at higher rates than ever before, but they are graduating at lower rates than their peers without disabilities. The Americans with Disabilities Act and Section 504 of the Rehabilitation Act have made it possible for students with disabilities to avail themselves of services in higher education to maximize their potential. To implement laws and provide equal access to students with disclosed disabilities (SWDD), many higher education institutions use central offices to serve students with disabilities. The survey in this study collects information from disability office directors regarding services provided and office characteristics.

The …


A Case Study Of A Jail Participating In An Animal-Assisted Crisis Response Program, Erica Schlau Apr 2019

A Case Study Of A Jail Participating In An Animal-Assisted Crisis Response Program, Erica Schlau

Dissertations

A crisis state is often the result of being admitted to jail, due to the catastrophic impact incarceration can have on personal and professional lives. Unlike other studies, the present study focuses on inmates in jail rather than in prison. To address jail inmates in a crisis state, the current best practice is suicide prevention, which does not effectively consider the needs of jail inmates. Recently emerging in the literature is the use of animal-assisted crisis response (AACR) to serve individuals experiencing a crisis. There is a lack of research on the use of animal-assisted interventions (AAI) with the population …


Serial And Concurrent Response Presentation: Their Effects On Resurgence, Michael P. Kranak Apr 2019

Serial And Concurrent Response Presentation: Their Effects On Resurgence, Michael P. Kranak

Dissertations

Serial response training (SRT) may mitigate resurgence of a target response when compared to teaching a single alternative response. However, the necessity of the serial presentation of alternatives is yet to be determined. We hypothesized teaching alternative responses at the same time (concurrent response training [CRT]) may be as effective as, and more efficient than, SRT. We used a multielement design embedded within an ABC resurgence arrangement in a human operant arrangement in three studies. Twenty-seven undergraduate students enrolled in a psychology course participated. In Study 1, we compared CRT to differential reinforcement of a single alternative response (traditional DRA). …

Development Of An Instrument To Measure Hope, Judith Fitzgerald Miller Mar 2019

Development Of An Instrument To Measure Hope, Judith Fitzgerald Miller

Dissertations

The purpose of this study was to develop an instrument to measure hope in adults and to evaluate its psychometric properties. A forty item Miller Hope Scale was developed based on the critical elements of hope gleaned from a comprehensive review of literature, including the etymology of hope; as well as from an exploratory study of hope in persons who survived a critical illness. The instrument was critiqued by psychometric and content experts, content validity established and was pretested on 75 subjects. Psychometric properties of the refined instrument were determined by studying 522 healthy adults.


Building A Social Identity: Peer-To-Peer Sexual Harassment In Adolescents, Denise Giannascoli Link Mar 2019

Building A Social Identity: Peer-To-Peer Sexual Harassment In Adolescents, Denise Giannascoli Link

Dissertations

Peer-to-peer sexual harassment is pervasive in secondary schools and is responsible for a number of health effects such as sleeplessness, loss of self-esteem and depression, as well as other negative educational and social effects (AAUW, 1993; Morrisey, 1995; PCSW, 1995; vanRoosmalen & McDaniel, 1998). As a behavior that is learned, the incidence of peer-to-peer sexual harassment may be reduced through interventions aimed at changing inappropriate and harmful behavior. The purpose of this study was to describe and explain the basic social psychological process that induces and perpetuates peer-to-peer sexual harassment in adolescents. In order to achieve this goal, it was …


College Student Risk Behavior: The Implications Of Religiosity And Impulsivity, Mary A. Cazzell Mar 2019

College Student Risk Behavior: The Implications Of Religiosity And Impulsivity, Mary A. Cazzell

Dissertations

College student risk-taking among 18 to 21 years olds includes smoking cigarettes, binge drinking, casual sex with multiple partners, automobile accidents due to risky driving or driving under the influence, and substance use. Among 10 to 24 year olds, 72% of all fatalities result from automobile accidents, unintended injuries, homicide, and suicide. Since not all college students participate in risk behaviors, protective factors such as religiosity may be a protective social or psychological buffer that supports positive relationships and moral order. Impulsivity, an inability to squelch inappropriate thoughts or actions, is associated with the later development (in the mid-twenties) of …


Public Policy Regarding Infant Mortality: Rhetorical Criticism Of The Mass Media, Joanne Rains Warner Mar 2019

Public Policy Regarding Infant Mortality: Rhetorical Criticism Of The Mass Media, Joanne Rains Warner

The Tenderness Process In Mother-Infant Couples: The Relationship Of Maternal Perception And Anxiety To Infant Satiety And Anxiety, Deidre Marion Blank Mar 2019

The Tenderness Process In Mother-Infant Couples: The Relationship Of Maternal Perception And Anxiety To Infant Satiety And Anxiety, Deidre Marion Blank

Dissertations

The purpose of the study was to identify what impact, if any, maternal perception and anxiety had on an infant at the time of feeding. The framework for testing the relationship was Harry Stack Sullivan's interpersonal theory of psychiatry, as it related specifically to mother-infant tenderness. For the study, tenderness was restricted to a reciprocal process in which the infant had a physiochemical need for milk and the mother a complimentary need to satisfy the infant. Of importance to Sullivan was the fact that an infant had to depend on the intervention of others for survival and therefore manifested a …

Alcohol Induced Bacterial Changes In The Setting Of Colitis, Paulius Kuprys Jan 2019

Alcohol Induced Bacterial Changes In The Setting Of Colitis, Paulius Kuprys

Dissertations

Inflammatory bowel diseases (IBD) affect a large number of individuals around the world. This group of diseases is largely composed of two types: Crohn's disease (CD) and ulcerative colitis (UC). Upon development of IBD, patients experience cyclical episodes of inflammation, known as flares. Flare induction appears to arise from multiple factors, which can also vary on a person-to-person basis. Alcohol has been shown to trigger IBD flares and onset, though the underlying mechanism has not been established.Defining factors of the IBD intestinal environment include an altered microbiome, bacterial infiltration of the intestinal epithelium, and increased leakage of proinflammatory bacterial byproducts. …


Generating Biologic And Genetic Research Tools To Investigate Serotype I Feline Coronaviruses, Robert Christian Mettelman Jan 2019

Generating Biologic And Genetic Research Tools To Investigate Serotype I Feline Coronaviruses, Robert Christian Mettelman

Dissertations

Serotype I feline infectious peritonitis virus (FIPV) is an alphacoronavirus of high veterinary importance due to the 99% mortality rate observed in cats. Since the 1980s, robust experimentation on these viruses has been limited by availability of culturable pathogenic strains, few permissive cell lines, and a lack of standardized methods to study their basic virology. These complications have resulted in variable and conflicting literature reports, have slowed study of clinical strains and hindered effective vaccine design. The goal of this dissertation was to develop a laboratory "toolbox" containing standardized methods, permissive cell lines and genetic techniques to alleviate some of …

An important aspect of this study is the detailed characterization of the shear horizontal mode of the Lamb wave that is generated by simulated crack growth. This analysis indicates that the amplitude of the shear horizontal mode remains …


Modulating The Tumor Microenvironment To Induce Cross-Priming For Cancer Immunotherapy, Erica Fleming-Trujillo Jan 2019

Modulating The Tumor Microenvironment To Induce Cross-Priming For Cancer Immunotherapy, Erica Fleming-Trujillo

Dissertations

Adoptive cell transfer (ACT) using T cells engineered to express tumor-specific T cell receptors (TCR) holds great promise in treating cancer patients. ACT involves the in vitro generation of large numbers of tumor-specific T cells, which are then administered back to the patient, to establish an in vivo response and effective tumor control. Our lab conducted a phase I clinical trial in which metastatic melanoma patients received systemic infusions of autologous T cells transduced to express a tyrosinase-specific TCR (TIL 1383I). We observed tumor regression in one of seven patients and the development of vitiligo, indicative of T cell-mediated killing …


Elucidation Of The Molecular Mechanisms Of Electrically-Induced Cardioprotection, Anne Elizabeth Roessler Jan 2019

Elucidation Of The Molecular Mechanisms Of Electrically-Induced Cardioprotection, Anne Elizabeth Roessler

Dissertations

Cardiovascular disease is the leading cause of death worldwide. A myocardial infarction (MI), commonly known as a heart attack, is a major event in cardiovascular disease characterized by reduced blood flow to the heart. The ischemia and reperfusion (I/R) injury associated with an MI results in a region of dead tissue in the heart called an infarct, the size of which influences patient prognosis. In the 1980s, it was discovered that short, non-lethal episodes of I/R, termed ischemic preconditioning (IPC), can protect the heart against a subsequent MI. Ischemic preconditioning demonstrated the phenomenon of endogenous cardioprotection. Cardioprotection has great potential …
