Distribution And Occurrence Of Escherichia Coli In Water And Sediments At Grand Glaize Beach In Lake Of The Ozarks State Park, Jordan Lee Wilson

Masters Theses

"Public swimming beaches at the Lake of the Ozarks State Park (LOSP) are popular vacationing spots for many Missourians; however, on several occasions Escherichia coli (E. coli) concentrations have exceeded standards set by the Missouri Department of Natural Resources (MDNR). Exceedances lead to beach closures which not only represent a potential public health threat but are also detrimental to the local economy and the public's perception of the lake's general water quality. In a collaborative effort between Missouri S&T, the United States Geological Survey (USGS) and the MDNR, an in-depth, two-summer study was conducted which included collection of …

The Church Of Craiglockhart: Wilfred Owen And Siegfried Sassoon‘S Critique And Use Of Religion In Their World War I Poetry, Brian Karsten

Masters Theses

Throughout history, faith and religious principles have been used as motivation for war. Accordingly, political leaders, religious leaders, and writers all used religion-themed propaganda to encourage enlistment in World War I. Two soldier poets, Siegfried Sassoon and Wilfred Owen, after meeting in the asylum of Craiglockhart, together recognized the injustice represented in using faith to promote warfare. Subsequently, they wrote poetry which criticized the religious and political hierarchy, countered the theology used in propaganda, and attempted to reveal the atrocities in battle. Although Sassoon‘s poetry remained satirical of the use of religion, Owen recognized its power and used religion and …

"His Head Rolled Forth Onto The Floor:" Women, The Abject, And The Male Gaze In Old English Poetry, Jaime Michelle Myers

Masters Theses

Old English poetry features several female characters who challenge androcentric authority by violently killing men. I argue in this thesis that three of these women—Modthryth, Grendel’s mother, and Judith—are linked together by their rejection or reversal of the male gaze. In their forceful refusal to be visually objectified, each character is portrayed as abject—outside of normal and outcast from community. They cause disorder, illustrate the fragility of androcentric control, and force a confrontation with death. In so doing, they create ambiguity and, at times, reverse the subject/object and masculine/feminine gender binaries.

The Role Of Saturated Fatty Acids In Connexin Expression On Endothelial Cells And Eosinophils, Kurt Anthony Ashack

Masters Theses

Eotaxin is a potent chemoattractant for eosinophils that becomes elevated in the tissues in response to inflammation and increased adiposity. Therefore, eosinophil migration into adipose tissue should increase in diet-induced obese individuals, yet it does not. This suggested to us that something within the cellular microenvironment of diet-induced obese individuals might be altering the endothelial leukocyte adhesion molecules (ELAM) such as VCAM-1 or selectins on the endothelial cells, thus preventing eosinophils from entering the inflamed tissue. Connexons are gap junctions in endothelial cells and on immune cells such as macrophages that are composed of connexins and have been shown to …

Masters Theses

SHAPE Magazine is a women's fitness magazine that has been consistently popular since its initial publication in 1981. This study explores how the messages of health and beauty in this publication have evolved over the last three decades, especially in response to the cultural imperatives of consumerism and feminism. It critically analyzes the visual and textual messages on SHAPE Magazine covers and in letters from the editor, which offer important examples of the ways in which SHAPE attempts to “hail” readers – to draw them in, to convince them that what the magazine has to offer is relevant to their …

Can You Get Beliefs From Retweets? An Examination Of The Extended Parallel Processing Model On Social Media, Xialing Lin

Masters Theses

The Extended Parallel Processing Model (EPPM; Witte, 1992) has been applied as a framework to examine risk information dissemination and effective sensation seeking in various health communication scenarios. Previous studies suggest that it is worth examining whether Twitter could have potential efficacy effects similar to face-to-face interaction or traditional media interventions. Given the overload and discrete information in the medium environment, people would adapt information processing short cuts, to tend to similar perceptions from various sources rather than reading specific messages.

The current study investigates the threat appeal perceptions of EPPM on system-generated and other-generated message cues in social media. …

The Mouse Who Ruled His Kingdom: An Agenda Setting Analysis Of The Walt Disney World Company, Jacob Overbey

Masters Theses

People are seeking their news in more social environments, but very little research has been conducted on agenda setting and online environments. This thesis examined the agenda setting relationship between an organization on Twitter, @WaltDisneyWorld (i.e., The Walt Disney World) and public opinion on Twitter. The relationship was examined using Twitter's database of tweets to measure public opinion on Twitter. Since the news media is losing steam on the ability to break news, and social media is growing rapidly, this study tested the value of the agenda setting theory on social media.

Operating The Silencer: Muted Group Theory In The Great Gatsby, Sarah Funderbruke

Masters Theses

This master's thesis examines gender and social roles seen in dialogue in the American classic novel, The Great Gatsby, by F. Scott Fitzgerald. The researcher conducted a coding and rhetorical analysis to determine if elements of muted group theory were in the novel. Muted group theory was developed by Edwin and Shirley Ardener after their research indicated that a culture's values and social structure were voiced through rhetoric. The theory states that dominance in certain groups mutes, or silences, others from communicating effectively. Five passages from The Great Gatsby were selected for this analysis. These passages highlighted dialogue between the …

Masters Theses

The purpose of this rhetorical study is to examine the textual charisma of Thomas Paine's Common Sense and Daniel Hannan's speech "The Devalued Prime Minister of a Devalued Government" and how that charisma made these artifacts successful in spreading outrage surrounding the historical and political events of their respective eras. The author uses Weber's theory of charisma filtered through Rosenberg and Hirschberg's expanded theory identifying lexical charisma, or the charisma of messages. The author analyzes Paine's and Hannan's use of persuasiveness, believability, and powerfulness, translating each of these characteristics into specific cues that can be identified in the individual texts. …

Catalytic Engineering Of The Flagellin Protein, Alexandra M. Haase

Masters Theses

Flagellin is the protein monomer that comprises the bacterial flagella for most bacteria, including Salmonella typhimurium. This protein has attracted attention for protein engineering because it is exported out of the cell, polymerized into stable fibers, is produced in large quantities and is relatively simple to purify. Using rational design with computer modeling, potential active sites in the flagellin protein structure were modeled after the human carbonic anhydrase II tetrahedral zinc binding site. In total, three locations were selected as potential active sites and the necessary mutations were successfully introduced. Flagella formation for the flagellin variants was demonstrated through …

Creating A Millennial Generation Contextualized Church Culture, Christopher Deitsch

Masters Theses

Promoting Understanding Of Informed Consent, Michael N. Reynolds

Masters Theses

Several studies have shown that research participants who have consented to participate in a study often have limited comprehension of the information presented in the informed consent process. This study compared performance on an end-of-study consent document information retention measure between a read-and-sign consent procedure control group and an enhanced consent procedure experimental group. The enhanced consent procedure consisted of a pre-consent educational module and a question-and-answer style consent document. The control group scored an average of 78.7% correct on the multiple-choice question measure of participant retention of information contained within the consent documents. The experimental group scored an average …

I'M The Same Me: Communication And Renegotiation Of Identity In The Weight-Loss Surgery Experiences Of Women, Heather D. Schild

Masters Theses

Adult obesity rates are on the rise in the United States according to the Centers for Disease Control (2009) which has led to an increase in obesity-related illnesses such as diabetes and heart disease. Weight-loss surgery (WLS) has become accepted as a "cure" for obesity by the medical community. There has been a dramatic increase in the number of obese individuals electing to undergo WLS every year; 82% of these individuals are women (AHRQ, 2007). More women may be electing to undergo these procedures than men due to the pressures women face in American culture to achieve social standards of …

The Effects Of Berberine And Nitroxl (Hno) On The Glucose Uptake In L929 Fibroblast Cells, Jude Terver-Jeremiah Chenge

Masters Theses

Berberine, which has a long history of use in Chinese medicine, has recently been shown to have efficacy in the treatment of diabetes. While the hypoglycemic effect of berberine has been clearly documented in animal and cell line models, such as 3T3-L1 adipocytes and L6 myotube cells, the mechanism of action appears complex with data implicating activation of the insulin signaling pathway as well as activation of the exercise or AMP kinase-mediated pathway. There have been no reports of the acute affects of berberine on the transport activity of the insulin-insensitive glucose transporter, GLUT1. Therefore, we examined the acute effects …

The Truth Shall Set You Free: The Bible, The Revolution, And The Debate Over Slavery In The American South, Kevin Simon

Masters Theses

Before the slavery debate pushed a divided American nation to the brink of civil war, the argument divided the family of God. By the time cannon fire erupted at Fort Sumter, Christians had already staked out positions based on sophisticated lines of argument they used to justify or condemn chattel slavery. The generation coming of age during the Civil War era witnessed a debate more intense and contentious than their ancestors had seen, but in terms of the arguments employed, it broke very little fresh ground. Contrary to the assumption that antebellum apologists in the South invented the defense of …
