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.

New Effects Of Aging And Lattice Intercalation On Surface Properties Of Titanate Nanobelts, Roger Williams

Graduate Theses and Dissertations

Titanate nanobelts (NBs) have structural characteristics beyond that of clays. Due to a negatively charged lattice matrix of edge-shared TiO6-octahedra, the location of intercalated cations within the interlayer space may dictate the charge-conductions. This environment may in turn govern the lattice-framework's stability and surface properties, based upon our preliminary

data.

On that basis, these nanomaterials have been found in our lab to possess superb biological compatibility that is closely related to the types of the intercalated cations. In addition, a prolonged agitation was proven to enable us to manipulate the titanate NBs' length. In a parallel study, a ripening was …

Cad Tools For Synthesis Of Sleep Convention Logic, Parviz Palangpour

Graduate Theses and Dissertations

This dissertation proposes an automated flow for the Sleep Convention Logic (SCL) asynchronous design style. The proposed flow synthesizes synchronous RTL into an SCL netlist. The flow utilizes commercial design tools, while supplementing missing functionality using custom tools. A method for determining the performance bottleneck in an SCL design is proposed. A constraint-driven method to increase the performance of linear SCL pipelines is proposed. Several enhancements to SCL are proposed, including techniques to reduce the number of registers and total sleep capacitance in an SCL design.

"An Ample Provision For Our Posterity": Transportation, Ceramic Diversity, And Trade In Historic Arkansas, 1800-1930, Katherine Rose Cleek

Graduate Theses and Dissertations

In this dissertation I present a method to study transportation using ceramic diversity and access to transportation infrastructure. Ceramic tableware richness, or the number of types present, is analyzed over time as a proxy for access to local transportation infrastructure at seven sites in Arkansas, dating from approximately 1800 to 1930. Previous efforts to look at trade in historical archaeology including Adams (1976), Riordan and Adams (1985), and Adams, Bowers, and Mills (2001) have not thoroughly assessed transportation as a means of trade. This dissertation looks at the many ways of assessing diversity in archaeology, biology, business, and economics, as …
