Learning Experiences And Perspective Transformation In Evangelical Faith-Based Adult Nonformal Education Programs, Philip Gerke

Graduate Theses and Dissertations

The study adapted an existing instrument to examine perspective transformation and its associated factors in participants of evangelical faith-based adult nonformal education in the Midwestern United States. Stratified random one-stage cluster sampling of 11 churches produced a nonprobability sample (N = 597) that was significantly (p < .05) different from the population of the geographical location of the study. An 86% majority self-reported a level of agreement or stronger of perceived transformation of perspectives, but differences predicted by gender were insignificant. The difference in perceived perspective transformations between respondents aged 40-59 that had the highest levels and respondents aged 60 and above that had the lowest levels was significant. The factors of influential individuals, personal reflection, and thought-provoking learning assignments significantly predicted all four factors of perspective transformation; the Writing Assignment factor was a significant negative predictor of only the Perception of Change factor, and a significant positive predictor of only the Future Benefits factor. The study recommended that additional research on faith-based frames of reference and age category differences. The study also recommended that faith-based practitioners consider emphasizing transformative learning experiences and personal reflection in their programs for adults.

A Mixed-Method Examination Of Homicides Targeting Lgbt Individuals In The United States, Kristin Kaye Kelley

Graduate Theses and Dissertations

The purpose of the current study is to understand the dynamic processes of fatal attacks against lesbian, gay, bisexual, and transgender (LGBT) individuals across different situational circumstances. Recent scholarship has begun to identify the heterogeneous nature of anti-LGBT homicides, including possible differences in how victims are targeted by offenders. However, several limitations of prior research have stunted the systematic examination of these circumstances. Few studies, for instance, have disaggregated by crime type and bias type, thus masking unique patterns and causal processes associated with varying types of anti-LGBT homicide events. Others have relied on official data sources whose validity and …

Woes Of The Arkansas Internationalist: J. William Fulbright, The Middle East, And The Death Of American Liberalism, Mitchell Smith

Graduate Theses and Dissertations

Contemporary scholarship has shown that J. William Fulbright's defeat in 1974 was due to a plethora of reasons including his opposition to America's involvement in Vietnam, lackadaisical attitude towards the monolithic threat of Communism, connection to the Washington establishment amidst the Watergate scandal, and old age. Scholars, however, have not paid enough attention to the role Fulbright's Middle Eastern stances played in his final election campaign. I seek to place the voice of Arkansans in the national and international political discussions and show that, despite their relatively unfocused interest in Middle Eastern affairs (and perhaps because of that lack of …

Production Of Bioethanol By Fermentation Of Sugars Released By Dilute-Acid And Enzymatic Hydrolysis Of Soybean Meal, Deivis E. Lujan-Rhenals

Graduate Theses and Dissertations

Soybean meal (SBM) is a co-product of soybean oil extraction mostly used as animal feed due to its protein content ranging from 40 to 49%. Additionally, SBM contains 35-42% of carbohydrates, half of which are structural, and the remaining consists of approximately 17% of mono- and disaccharides--especially sucrose--up to 8% oligosaccharides, and 1-2% starch. When used as animal feed, only sucrose and starch are digested and absorbed by monogastric animals. Although SBM contributes carbohydrates to their diet, its main function is to provide proteins. Therefore, the selective removal of carbohydrates would create a protein-enriched meal with a greater value, which …

Abrasive grinding is widely used across manufacturing industry for finishing parts and components requiring smooth superficial textures and precise dimensional tolerances and accuracy. Unlike any other machining operations, the complex thermo-mechanical processes during grinding produce excessive friction-induced energy consumption, heat, and intense contact seizures. Lubrication and cooling from grinding fluids is crucial in minimizing the deleterious effects of friction and heat to maximize the output part quality and process efficiency. The conventional flood grinding approach of an uneconomical application of large quantities of chemically active fluids has been found ineffective to provide sufficient lubrication and produces waste streams and pollutants …

Interactions Between Ions And Lysenin Nanochannels And Their Potential Applications As Biosensors, Radwan Awwad Al Faouri

Graduate Theses and Dissertations

Lysenin is classified as a pore-forming toxin protein that is isolated from the earthworm Eisenia fetida and consists of 297 amino acids [1]. Lysenin inserts large conducting pores (3.0-4.7 nm in diameter) into artificial membranes (BLM) which include sphingomyelin. These pores (channels) are open and oriented upon insertion into the bilayer lipid membrane. Lysenin channels gate at positive voltages (voltage-induced gating), but not at negative voltages. Lysenin pores also exhibit activity modulation in response to changes in ionic strength and pH, indicating that electrostatic interaction is responsible for Lysenin conductance activities. In this line of inquiries, and by modulating Lysenin …
