The use of …

Preparation Of A Flavonol Specific Glucosyltransferase Found In Grapefruit And Site-Directed Mutants For Protein Crystallization, Aaron Birchfield

Electronic Theses and Dissertations

This research was designed to determine the conditions necessary to remove c-myc and 6x-His tags from a flavonol specific glucosyltransferase found in grapefruit (CP3GT) using thrombin in preparation for crystallization. X-ray crystallography of CP3GT crystals may elucidate structural features that account for flavonol specificity in some glucosyltransferase enzymes. A thrombin cleavage site was inserted into WT CP3GT and one mutant. Recombinant CP3GT was expressed in yeast and purified. Optimal conditions for thrombin digestion were explored. Digestion with 100U of thrombin for 2 hours at 4^o C was optimal for removing tags from CP3GT. Storage at 4^o C for …

Seeing The World Differently. An Exploration Of A Professional Development Model Bridging Science And Lay Cultures, Michael D. Garrett

Electronic Theses and Dissertations

This study explores the rationale, efficacy, and social validity of a professional development model designed to move elementary school science activities closer to the practices of working scientists as required by the United States’ “Next Generation Science Standards.” The model is culturally sensitive and aims to create experiences with high subjective task value. The formal theory of change uses scaffolding, Piagetian agency, and Vygotskian learning opportunities to argue that culturally familiar representational tasks in culturally natural intersubjective contexts can lead to work prototypical of scientific modeling under particular facilitation conditions: when participants (a) are allowed free use of their cognitive …

Land Beneath The Water: Narratives Of The Keowee-Toxaway Project In Appalachian South Carolina, Austin Gregory

Electronic Theses and Dissertations

In 1965, Duke Power announced the construction of a series of dams along the Keowee and Little rivers in Oconee County, South Carolina. The dams would create water reservoirs for one of the largest hydro-electric and nuclear power facilities in the nation. The dominant narrative focuses on the recreational activities, power generation, and economic development facilitated by the creation of lakes Jocassee and Keowee. 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 …

Inversed Learning In An Intermediate Accounting Course, Ashley B. Bentley

Electronic Theses and Dissertations

Students enrolled in accounting courses often struggle because of the complexity of the topic. Accounting instructors have searched for effective means of fostering student success, but the learning process continues to change. Critical thinking and problem solving abilities are vital for students and future professionals. Thus, teaching should not be limited to the transmission of information. By moving the dissemination of basic knowledge outside the classroom inversed learning allows class time for deep dives into complex topics and hands-on activities. Students who are actively involved in learning tend to be more successful in the classroom.

The purpose of this study …

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 …

Children Of A One-Eyed God: Impairment In The Myth And Memory Of Medieval Scandinavia, Michael David Lawson

Electronic Theses and Dissertations

Using the lives of impaired individuals catalogued in the Íslendingasögur as a narrative framework, this study examines medieval Scandinavian social views regarding impairment from the ninth to the thirteenth century. Beginning with the myths and legends of the eddic poetry and prose of Iceland, it investigates impairment in Norse pre-Christian belief; demonstrating how myth and memory informed medieval conceptualizations of the body. This thesis counters scholarly assumptions that the impaired were universally marginalized across medieval Europe. It argues that bodily difference, in the Norse world, was only viewed as a limitation when it prevented an individual from fulfilling roles that …

Teachers suggested meaningful changes to teacher preparation programs, including changes to general prerequisites and reorganizing education programs around meaningful field …

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 …

I will touch on the mindset behind as well as the effects of victim blaming, …

Performing Bernarda: Activating Power And Identity, Ana Martinez Medina

Electronic Theses and Dissertations

The musical Bernarda Alba tells the story of a woman who is confined within the heavily patriarchal and Catholic society that was 1930s Spain. Because of this, I thought it the perfect arena to explore power dynamics on stage. My thesis will explore status, hierarchies, relationships, and identity via the stolid matriarchal character Bernarda Alba. Through analyzing the playwright's words, fleshing out the character, and exploring the character's relationships with others in rehearsal, I have studied how to activate status on stage. There are many sociology theories and psychological studies that can be applied to theatre-making in order to create …

Gender Performance In Shakespeare's Twelfth Night, Amanda Lee

Electronic Theses and Dissertations

Cross-dressing is a recurrent theme in Shakespeare's comedies, and the theatrical trend of gender bending casting has added an extra layer of complexity to performing his work. How does the gender of the actor affect the performance of a role in Shakespeare? How does it affect the perception of the role, and how can an actor utilize that perception to connect more fully with the audience? How does the female perspective illuminate hitherto unexplored elements of Shakespeare's text and characters? I was inspired by Orlando Shakes' all male production of Twelfth Night to research gender theory in relation to classical …

The Change Process And The Implementation Of High School Jostens Renaissance Programs: A Multiple Case Study, Gregory G. English

Jostens Renaissance is one such program and was the program of focus for this study. Though Jostens has numerous publications and media sources to facilitate the sharing of ideas, there is very little information available regarding the implementation of Renaissance.

The primary purpose of this study was to identify factors that facilitated change in the process of implementing high school Jostens Renaissance programs in order to …

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 …

For Natural Philosophy And Empire: Banks, Cook, And The Construction Of Science And Empire In The Late Eighteenth Century, Ryan Barker

Electronic Theses and Dissertations

Using part of James Cook’s first voyage of discovery in which he explored the Australian coast, and Joseph Banks’s 1772 voyage to Iceland as case studies, this thesis argues that late eighteenth-century travelers used scientific voyages to present audiences at home with a new understanding and scientific language in which to interpret foreign places and peoples. As a result, scientific travelers were directly influential not only in the creation of new forms of knowledge and intellectual frameworks, but they helped direct the shape and formation of the Empire. The thesis explores the interplay between institutional influence and individual agency in …

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 …

A Comparison Of Standard Denoising Methods For Peptide Identification, Skylar Carpenter

Electronic Theses and Dissertations

Peptide identification using tandem mass spectrometry depends on matching the observed spectrum with the theoretical spectrum. The raw data from tandem mass spectrometry, however, is often not optimal because it may contain noise or measurement errors. Denoising this data can improve alignment between observed and theoretical spectra and reduce the number of peaks. The method used by Lewis et. al (2018) uses a combined constant and moving threshold to denoise spectra. We compare the effects of using the standard preprocessing methods baseline removal, wavelet smoothing, and binning on spectra with Lewis et. al’s threshold method. We consider individual methods and …
