Localization Of A Microsporidia Adam (A Disintegrin And Metalloprotease Domain) Protein And Identification Of Potential Binding Partners., Carrie E. Jolly

Electronic Theses and Dissertations

Microsporidia are spore-forming, obligate intracellular pathogens typically associated with opportunistic infections in immunocompromised individuals. Treatment options for microsporidia infections in humans are limited and additional research is necessary to create better therapeutic agents. For many pathogenic organisms, adhesion to the host cell surface is a prerequisite for tissue colonization and invasion. Our previous research has demonstrated a direct relationship between adherence of microsporidia spores to the surface of host cells and infectivity in vitro. In an effort to better understand adherence, we have turned our attention to determining what proteins may be involved in this process. Examination of the …

From Teacher To Teller: How Applied Storytelling Informs Autobiographical Instruction., Peggy Rosann Kent

Electronic Theses and Dissertations

This thesis uses autobiographical inquiry to "re-member" how I came to understand that applied storytelling was a valid teaching tool in facilitating autobiographical expression in mature learners. It is an examination of how story sharing and story listening can transform a continuing education classroom into a learning community. Applied storytelling can help elders reframe their negative mental models about the value of their stories, memory, and mythology and create opportunities for positive story sharing experiences. I selected highlights of my journey that best represented my experience and use of applied storytelling techniques. Each chapter includes an exercise and reflection as …

"Reclaiming The Child": Mountain Mission School As A Successful Appalachian Home Mission., Rachel Rebecca Hood

Electronic Theses and Dissertations

Mountain Mission School of Grundy, Virginia, founded by Samuel Robinson Hurley in 1921, is an anomaly of the mission school era of 1880 to 1940. Unlike other mission schools, Mountain Mission School was independent from its inception and was founded by a self-taught, self-made millionaire from southwest Virginia. The school's purpose to "reclaim" the child from material and spiritual poverty lay in Hurley's desire to develop a child's mind, body, and soul through a Christian, industrial education. Through personal commitment to the school and tireless fund-raising efforts for the school, he inspired others to continue the mission he began. Primary …

Electronic Theses and Dissertations

The postwar children coming of age in the late 1960s in West Germany mounted a widesweeping socio-political protest against what they saw as the strangling silence of their parents, the Nazi generation. These protesters, referred to as the 68ers for their pivotal year, continued their struggle in following decades, incorporating an important and controversial exhibition, and finally culminating in their own administration thirty years from their defining moment. Using such diverse kinds of information as parliamentary debates, interviews, and contemporary criticism, this thesis explores the impact of the 68ers' initial protest and the influence they ultimately had on their nation …

And This, Our Measure: Figurative Realism And Workaday Culture., Perry Walter Johnson

Electronic Theses and Dissertations

Man has created vast and powerful systems. These systems and their associated protocols, dogmas, and conventions tend to limit rather than liberate. Evaluation based on homogeneity threatens the devaluation of our humanity. This paper and the artwork it supports examine contemporary culture and its failings in the stewardship of the humanist ideal.

My paintings referenced herein are satirical narratives. The story told is one of alienation and evisceration. The visual subject matter is the human figure and environments dominated by architectural geometry. The male figures are conspicuously turned from view, a visual cue to their estrangement. Parallel and subordinate thoughts …

This project represents an effort to summarize existing knowledge on the house, to address common misconceptions, and to create an interpretive kiosk design based on historical research.

A Kenyan Revolution: Mau Mau, Land, Women, And Nation., Amanda Elizabeth Lewis

Electronic Theses and Dissertations

The Kikuyu, the largest ethnic group in Kenya, resisted colonial authority, which culminated into what became known as Mau Mau, led by the Kenya Land Freedom Army. During this time, the British colonial government imposed laws limiting their access to land, politics, and independence. The turbulent 1950s in Kenyan history should be considered a revolution because of its violent nature, the high level of participation, and overall social change that resulted from the war.

I compared many theories of revolution to the events of the Mau Mau movement. Then, I explained the contention for land in the revolution, the role …

New Technique For Imputing Missing Item Responses For An Ordinal Variable: Using Tennessee Youth Risk Behavior Survey As An Example., Andaleeb Abrar Ahmed

Electronic Theses and Dissertations

Surveys ordinarily ask questions in an ordinal scale and often result in missing data. We suggest a regression based technique for imputing missing ordinal data. Multilevel cumulative logit model was used with an assumption that observed responses of certain key variables can serve as covariate in predicting missing item responses of an ordinal variable. Individual predicted probabilities at each response level were obtained. Average individual predicted probabilities for each response level were used to randomly impute the missing responses using a uniform distribution. Finally, likelihood ratio chi square statistics was used to compare the imputed and observed distributions. Two other …

Hearing Adam: Gender Relationships In The Short Fiction Of Caroline Gordon., Linda Elaine Hipple

Electronic Theses and Dissertations

Writer and critic Caroline Gordon has been a participant on the Southern literary scene since the early 1930s, yet her works have been neither studied nor appreciated as frequently as the works of her male contemporaries. Her novels and short fiction never received the critical acclaim that they merited due to the perpetuation of the erroneous idea that women have little to say. While at the time other female writers were exploring their emancipation, Gordon retreated to the consistent confines of male-dominated tradition and created fiction embodying her conservative philosophy. This thesis will examine five pieces of her short fiction, …

Examining Significant Differences Of Gunshot Residue Patterns Using Same Make And Model Of Firearms In Forensic Distance Determination Tests., Heather Lewey

Electronic Theses and Dissertations

In many cases of crimes involving a firearm, police investigators need to know how far the firearm was held from the victim when it was discharged. Knowing this distance, vital questions regarding the re-construction of the crime scene can be known. Often, the original firearm used in commission of a suspected crime is not available for testing or is damaged. Crime laboratories require the original firearm in order to conduct distance determination tests. However, no empirical research has ever been conducted to determine if same make and model firearms produce different results in distance determination testing. It was the purpose …
