[Re]Visiting The Rime: A Case Study Of Adaptation As Process And Product With The Rime Of The Ancient Mariner, Sally Ferguson

Graduate Theses and Dissertations

This thesis combines adaptation theory with ecology to examine Samuel Taylor Coleridge's Rime of the Ancient Mariner (1798) and its adaptations; it argues further combinations of adaptation with evolutionary theory and ecological ideas could allow for a better interpretation of many texts. The adaptation Rime of the Modern Mariner (2011) by Nick Hayes and the appropriation Perelandra (1943) by C.S. Lewis will also be present in individual chapters to examine the texts' interactions with each other as they evolve and how each work represents the combined theory.

A Watchman On The Walls: Ezekiel And Reaction To Invasion In Anglo-Saxon England, Max K. Brinson

Graduate Theses and Dissertations

During the Viking Age, the Christian Anglo-Saxons in England found warnings and solace in the biblical text of Ezekiel. In this text, the God of Israel delivers a dual warning: first, the sins of the people call upon themselves divine wrath; second, it is incumbent upon God’s messenger to warn the people of their extreme danger, or else find their blood on his hands. This thesis examines how the Anglo-Saxon applied Ezekiel’s warnings to their own cultural crisis. It begins with the early development of this philosophy by the Britons in the 500s, its adoption by the Anglo-Saxons, Irish, and …

Exploring Privacy Leakage From The Resource Usage Patterns Of Mobile Apps, Amin Rois Sinung Nugroho

Graduate Theses and Dissertations

Due to the popularity of smart phones and mobile apps, a potential privacy risk with the usage of mobile apps is that, from the usage information of mobile apps (e.g., how many hours a user plays mobile games in each day), private information about a user’s living habits and personal activities can be inferred. To assess this risk, this thesis answers the following research question: can the type of a mobile app (e.g., email, web browsing, mobile game, music streaming, etc.) used by a user be inferred from the resource (e.g., CPU, memory, network, etc.) usage patterns of the mobile …

The Role Of Hydrologic Regimes In Driving Morphologic Divergence And The Trait Compositions Of Fish Assemblages, Lindsey A. Bruckerhoff

Graduate Theses and Dissertations

The hydrologic regime is an important determinant of the ecological integrity of a stream. Hydrologic regimes are defined by the magnitude, timing, frequency, rate of change, and duration of high and low flow events and capture long term patterns of variability and predictability of water movement in a stream. Flow regimes influence many aspects of the biophysical environment in lotic systems; therefore organisms have adapted to natural flow patterns. We investigated how fish have adapted to flow regimes at both a population and community level. In the first study presented in this thesis, we hypothesized fish exhibit phenotypic divergence to …

Teachers' Beliefs And Practices About Grammar Teaching In Public High Schools In Kosovo, Marigona Morina

Graduate Theses and Dissertations

Many linguists have tried to answer when and how to teach grammar based on research, as well as whether to teach grammar at all. On the other hand, for many teachers, grammar is the backbone of language learning (Sitorus, 2012). This paper analyzes teachers’ beliefs and practices and their relationship regarding grammar teaching in Kosovo’s public high schools. Teachers’ beliefs are resistant to change (Williams & Burden, 1997); knowing what the majority of teachers in Kosovo believe to be true regarding grammar and language teaching can lead to an update on the curriculum of English Language Teaching programs in order …

Development Of Pre-Stressed Cfrp Fatigue Retrofits For Common Steel Bridge Connections, Korey Albert Pough

Graduate Theses and Dissertations

Aging or deterioration of the nation’s bridge infrastructure is a significant issue that requires attention. Causes for much of this deterioration can be attributed to two main factors, 1) corrosion, and 2) metallic fatigue, both of which work together to reduce the strength and serviceability of bridge components over time. In many instances, strengthening of bridge components using localized retrofits offers an economical and fast solution for increasing the longevity of existing steel bridges; however, such retrofits must be resilient to further corrosion and fatigue damage. In this study, a localized retrofit is developed using pre-stressed Carbon Fiber Reinforced Polymer …

The first QTL was located on the chromosomal region where the slow-melting flesh (SMF) DNA test was identified, and the second QTL was …

Validation Of Soil-Test-Based Phosphorus And Potassium Fertilizer Recommendations For Rice And Soybean, Matthew Scott Fryer

Graduate Theses and Dissertations

The science of soil-testing for nutrient management and fertilizer recommendations is widely accepted among scientists and agronomists. Although this science is unsurpassed in predicting soil nutrient availability, soil-test interpretations are seldom validated. Major research objectives for irrigated soybean [Glycine max (L.) Merr.] and direct-seeded, delayed-flood rice (Oryza sativa L.) were to: i) validate the accuracy of Mehlich-3 soil-test P (STP) and K (STK) interpretations and ii) published critical tissue-P and -K interpretations in predicting the yield response to fertilizer at different significance levels (p≤0.05 to 0.25), iii) examine how seed nutrient concentrations are influenced by fertilization and crop response to …

On The Evolutionary Origins Of Religious Belief, Robert Duane Howard

Graduate Theses and Dissertations

Religious belief is a byproduct of evolutionarily designed cognitive mechanisms. The ubiquity of religious belief and experience across human cultures is explained by our common human psychology; our domain-specific cognitive mechanisms give rise, collectively, to the phenomenon of byproduct religious belief/experience. In this thesis, I will examine what I call religion-generating cognitive mechanisms, and I will argue that byproduct raw god-beliefs are developed by cultures into refined god-beliefs. These refined god-beliefs are co-opted by evolutionary processes and are cultural adaptations. My conception of “religious belief” in terms of raw and refined god-beliefs allows a disambiguation of the term “religion,” and …

Geospatial Workflows And Trust: A Use Case For Provenance, Rachel Frances Linck

Graduate Theses and Dissertations

At first glance the Astronomer by Vermeer, Tutankhamun’s burial mask, and a geospatial workflow may appear to have nothing in common. However, a commonality exists; each of these items can have a record of provenance detailing their history. Provenance is a record that shows who did what to an object, where this happened, and how and why these actions took place. In relation to the geospatial domain, provenance can be used to track and analyze the changes data has undergone in a workflow, and can facilitate scientific reproducibility. Collecting provenance from geospatial workflows and finding effective ways to use this …

Disaggregating The Effect Of Drought And Heat Stress During Flowering On Spikelet Fertility In Rice, Lisa Straussberger

Graduate Theses and Dissertations

Due to rice’s wide geographic distribution, extending from 50°N to 35°S, rice is

forecasted to be the most vulnerable crop to warming global climates. Previous studies have

predicted lower rice yields and increasing rice yield variability due to higher frequencies of heat

stress events, and a higher variability in precipitation patterns due to global warming. As such,

understanding the effects of drought and heat stress intensity and frequency on rice yields is of

upmost importance to feeding the growing global population.

Given that drought and high-temperature stress often occur together, it is essential to

disaggregate the two individual stressors and …

Towards Systematic Selection Of Terrain- And Ground Cover-Specific Lidar Filtering Parameters, Vance Green

Graduate Theses and Dissertations

Accurate automated classification of LiDAR point clouds is a well-known problem and proper parameterization of the classification algorithm is essential to creating useful bare-earth terrain models. Parameterization is particularly important in areas characterized by extremely low relief, such as the Little Red River Irrigation Project Area in central Arkansas. In this kind of landscape, analyses such as hydrological flow models are sensitive to small changes in the topography, and therefore prone to errors in the classification of the LiDAR point cloud and the digital elevation models (DEMs) derived from it. Developing effective project-specific parameters requires a high degree of knowledge …

The Validity Of Urine Color Self-Assessment As An Index Of Hydration In Males, Daniel Layne Nixon

Graduate Theses and Dissertations

While water intake is so important, there are few practical hydration assessment techniques for the general population to use on a daily basis. The present study examined the accuracy of self-assessed urine color (Ucol) as a potential hydration assessment tool. Male college aged subjects provided a urine sample into a custom built urinal (n=76; 1.79±0.76 m, 83.9±16.0 kg). The urinal contained a picture of the 1-8 color scale and a light and dark urine color scale. Subjects were asked to give their urine color estimation as a whole number integer and to estimate if their urine was light or dark. …

Wittgenstein's Liberating Word: A Meditation On Philosophy And God, Joshua Timothy Kenyon Daniel

Graduate Theses and Dissertations

This project is an attempt to understand the nature of religious belief through the lens of Ludwig Wittgenstein’s philosophical perspective. Chapter One outlines Wittgenstein’s approach to language and meaning and explores the tension that many contemporary analytic philosophers of religion find in Wittgensteinian approaches to religious belief. Chapter Two addresses concerns Wittgenstein had with Frege’s understanding of logic and the limits of thought and ties it to criticism from Wittgensteinian philosophers about the possibility of making any sense of religious belief. Chapter Three pulls together the concerns of the previous two chapters and attempts to reconcile them. A schematic outline …
