Geophysical And Remote Sensing Applications For A Better Understanding Of The Structural Controls On Groundwater Flow In The Lucerne Valley, California, Dale R. Dailey

Masters Theses

An integrated study was conducted in the Mojave Basin to investigate the potential role of faults and basement uplifts for groundwater flow in the Mojave Desert. Observations made include: 1) Very Low Frequency (VLF) measurements across mapped (using LIDAR and Geoeye-1 imagery) fault traces showed significant radio field dip angles indicative of presence of shallow sub-vertical, sheet-like conductors; many of the VLF tilt peaks coincided with changes in the magnetic profiles; 2) Vertical Electric Soundings indicate shallow basement west of, and parallel to, the Helendale Fault and deep saturated zones east of the fault/basement outcrop (F/B); and 3) isotopic analyses …

Hybridization Facilitates The Rapid Evolution Of Reduced Herbicide Sensitivity In The Widely-Managed Invasive Aquatic Plant, Eurasian Watermilfoil, Elizabeth Ann Larue

Masters Theses

Eurasian watermilfoil (Myriophyllum spicatum) is one of North American’s most invasive and widely managed aquatic weeds. Eurasian watermilfoil also hybridizes with the native northern watermilfoil (Myriophyllum sibiricum) to produce many invasive and genetically diverse populations of hybrid watermilfoils. Both Eurasian and hybrid watermilfoils are commonly controlled with herbicides, but there has been recent concern that some hybrids exhibit reduced herbicide sensitivity. There is a lack of studies comparing the response of Eurasian and hybrid watermilfoils to commonly used herbicides. To determine if hybrids exhibit reduced herbicide sensitivity, I compared the sensitivity of hybrid and Eurasian watermilfoil …

Archaeological Investigations Of Control And Autonomy At The Colony Farm Of The Michigan State Asylum, 1880-1950, Alison Thornton

Masters Theses

This project is designed to look into mechanisms of control and patient autonomy in institutional confinement, using Colony Farm in Kalamazoo, Michigan as a case study. I have chosen to specifically examine landscape, architecture, foodways, and personal goods/dress as avenues in which to parse out information regarding control and autonomy. The main themes throughout this paper are work as a cure, patient labor, and the blurring of roles between patients, staff members, and paid hired workers. These themes are intertwined with landscape, architecture, foodways, and personal goods/dress and highlight the contradictions inherent in institutional confinement, especially in the context of …

Don't Take Orpheus Without The Lyre: The Intricacies Of Using Pagan Myths For Christian Purposes In The Divine Comedy And Paradise Lost, Rebekah J. Waltmann

Masters Theses

Because of their universal and artistic nature, the classical myths lend themselves well to use in literature, especially poetry. When used properly, as by Dante and Milton, the myths have the ability to enhance the work; when used poorly, they become gaudy ornamentation. It was, and is, this ability to enhance both the artistry and function of literature that pulled so many poets to the myths, despite the difficulties that could arise when the pagan myths did not quite match the Christian setting. My purpose in this thesis is not to explicate every use of myth within The Divine Comedy …

Media Convergence Of Newspapers: A Content Analysis Of The Houston Chronicle's Print- And Web-Based Content, Amanda Sullivan

From A Rodent To A Rhetorician: An Ideological Analysis Of George Alexander Kennedy's Comparative Rhetoric, James Begley

Masters Theses

George Alexander Kennedy, a professor of classics at the University of North Carolina at Chapel Hill, has given birth to a new understanding of rhetorical studies: he argues for the evolution of rhetoric from animals to humans. Using Sonja Foss's methodology of "ideological criticism," this thesis examined Kennedy's case as presented in his book, Comparative Rhetoric: an Historical and Cross-Cultural Introduction. This study discovered that the book was heavily influenced by a secular, pro-evolutionary ideology which dually contributed to its selective use of scientific evidences and production of inconsistent arguments. Evaluated on the basis of Biblical principles, this thesis concluded …

Orientalism And Three British Dames: De-Essentialization Of The Other In The Work Of Gertrude Bell, Freya Stark, And E.S. Drower, Lynn Sawyer

Masters Theses

Although postcolonial criticism has run its course for thirty years, a fresh look at Edward Said's Orientalism offers insight into how Orientalism functions in the writings of three British dames. Gertrude Bell in The Desert and the Sown, Freya Stark in The Southern Gates of Arabia, and E.S. Drower in The Mandaeans of Iraq and Iran, however, challenge Said's theory. Their writing raises questions about how gender alters the discourse about the Other, and whether Said essentializes the Occident. Bell, Stark, and Drower serve as case studies in which to analyze the politically and rhetorically complex interactions between the West …

Reading Between The Lines: Gender Perception Of Lean Media, Jennalee Conner

Masters Theses

Over the years, communication methods have evolved from face-to-face conversations to computer-mediated communication including: e-mail, instant message, and text message interactions. Since the methods have changed, a large aspect of communication, nonverbal cues, have become nearly impossible. These methods of communication that lack nonverbal cues are therefore referred to as lean media because they lack the richness of facial expression, vocal expression, and immediacy. In order to modify more recent forms of communication to include nonverbal cues, individuals have created their own nonverbal cues. While each individual is unique, though, genders normally tend to think or behave in similar fashion. …

A Hierarchy Of Love: Myth In C.S. Lewis's Perelandra, Joseph Walls

Masters Theses

In C.S. Lewis's Perelandra, the transposed creature is drawn up into its "kindly stede" as a sacramental symbol of Christ through that fictional planet's unbroken relationship between meaning and form. Although Perelandra's "wheels-within-wheels" hierarchy may at first seem reminiscent of Catholicism's teachings on symbol, as a Protestant, Lewis believes that human beings cannot be truly sacramental symbols until the return of Christ. Lewis's optimistic depiction of a cosmic hierarchy is one of perfect love: superiors rule their subordinates with agape, and creatures who discover their submissive roles reciprocate with eros or adoring love. Every created being in Perelandra is part …

Gender And The Boundaries Of National Identity: U.S. Women As A Citizen Class In The Long 1960s, Sara Bijani

Masters Theses

This text analyzes the public ideologies and institutions that underpinned women's unequal status within the national collective of United States citizens during the long 1960s, paying particular attention to the executive office of Lyndon Johnson, Congress, and the national security establishment. Women were frequently framed within these institutions as a separate special class of citizen, with rights and responsibilities not akin to those of the elite—male bodied—members of the national collective. Allowing for the imaginative construction of "women" as a subject class in U.S. society, this text argues that even with the guarantee of formal political rights in place, women …

Understanding Wildfire Hazard Vulnerability Of Residents In Teton County, Wyoming, Lucas Kanclerz

Masters Theses

The research examines significant differences in wildfire home protection activities between local and seasonal residents in Teton County, Wyoming. Significant differences of wildfire home protection activities results in hazard vulnerability to a whole community. An extensive literature review establishes the purpose and hypothesis of the research to understand if seasonal residents are creating wildfire hazard vulnerability to local residents. A survey-based methodology using nominal YES/NO questions and ordinal Likert-type scale questions were used to understand residents past wildfire experiences, perceptions on the effectiveness of home protection activities, and if residents actually do these activities. Statistical analysis revealed that seasonal residents …

Heart Rate Artifact Suppression, Christopher Dickson

Masters Theses

Motion artifact strongly corrupts heart rate measurements in current pulse oximetry systems. In many, almost any motion will greatly diminish the system’s ability to extract a reliable heart rate. The artifact is most likely present due to normally non-pulsatile components of the body, such as venous blood and tissue fluid, which become pulsatile during motion. This paper presents a motion artifact reduction method using an accelerometer that attempts to recover a usable heart rate sensor signal that has been corrupted by motion. The method was developed for a wrist pulse oximeter sensor and was adapted for a ring sensor, both …

Effect Of Exercise On Adult Neurogenesis In Crayfish, Jennifer E. Klutts

Masters Theses

Adult neurogenesis, formation of new neurons, has been determined to be a part of the normal physiology in all species of animals studied to date. There have been several factors observed to increase the number of newly formed cells; the most potent of these factors being exercise. Though exercise has a strong effect on neurogenesis by increasing proliferation and new cell survival it has not been extensively studied in many model organisms. This study is the first to look at the effect of exercise on neurogenesis in an invertebrate through the use of crayfish, Orconectes propinquus. Experimental designs, drying protocols …

Effects Of Ailanthus Altissima Soil Leachates On Nodulation And Expression Of Two Genes That Regulate Nodulation Of Trifolium Pratense, Jesse Michael Lincoln

Masters Theses

Ailanthus altissima (Simaroubaceae) is an invasive tree from China that has spread over much of North America. A number of characteristics contribute to its success, notably tolerance of nutrient-poor soils, rapid growth rates, prolific production of wind dispersed seeds, escape from predation, and the production of allelopathic compounds. That Ailanthus altissima frequently co-occurs with legumes in nutrient poor soils alludes to a possible relationship between Ailanthus altissima and nitrogen fixing legumes. Legumes increase the biospheres supply of bio-available nitrogen through facilitating the fixation of atmospheric nitrogen within structures on roots called nodules. Thus, increased nodulation of legumes caused by Ailanthus …

Understanding Flight Delays At U.S. Airports In 2010, Using Chicago O'Hare International Airport As A Case Study, Paul Blackwood

Masters Theses

Flight delays are economic, social, and environmental albatross to U.S. businesses and consumers. In 2007 alone, domestic flight delays cost the U.S. aviation industry $40.7 billion (Joint Economic Committee of the House and Senate Report, 2008). These delays involved inconveniences for airlines and passengers, and untold misery for local and state officials. In that same year, delays forced U.S. airlines to consume an extra 740 million gallons of jet fuel (Joint Economic Committee of the House and Senate Report, 2008). The purpose of this study is to understand flight delays at U.S. airports and to determine how key causal factors …

Design Of A Catenoidal Shaped Anechoic Termination, Kyle Myers

Masters Theses

An analytical model is developed in this thesis to predict the reflection coefficient of an anechoic termination consisting of a catenoidal horn connected to a tube lined with absorbing material. The theoretical predictions are compared to experimental measurements on a prototype. Comparisons are made for a variety of arrangements, including, an open horn, and a horn connected to absorbing terminations of two different lengths. The absorbing terminations are either open or closed to the environment and the analytical model can account for both these scenarios. The results indicate that the new model can accurately predict the reflection coefficient for each …

Income Inequality And Social Stratification: The Effect Of Market Versus State In Transitional Urban China, Qiong Wu

Masters Theses

The rise of inequality in China is one of the most serious social problems in the reform era in China. Previous studies have debated the relative importance of human capital, political capital, and other factors in determining personal income. By using a new dataset from 2006 China General Social Survey (CGSS2006), I replicate earlier tests to measure whether the market or state has more impact on incomes as a way to the competing hypotheses related to human versus political capital.

The results of the ordinary least squares regression analysis show no significance in party membership, state ownership, and work experience, …

An Exploratory Study Of Perceptions Of Benefits And Barriers To Study Abroad For Students With Disabilities, Melissa Jean Kutsche

Masters Theses

Although roughly 11% of college students identify as students with disabilities, in 2009 only 3.6% of students who studied abroad were students with disabilities. Due to the lack of research on the topic, little is known about the reasons for this underrepresentation. In this exploratory study, qualitative data analysis was used to analyze responses to an open-ended survey distributed to 749 students with disabilities at a Midwestern university. Responses from 28 students indicate that students with disabilities perceive various benefits and barriers to study abroad, and that demographic characteristics such as type of disability, age, and marital status are not …

The Significance Of Silence: The Muted Voices Of Count Fosco And Laura Fairlie In The Woman In White, Melanie Page

Masters Theses

This thesis examines the intricacies of voice using narrative theory and reader-response theory with Wilkie Collins' The Woman in White. Since Collins first wrote this epistolary novel serially, he wrote aware of his audience as he printed segments with different narrators. This novel allowed Collins the opportunity to reveal an internal set of narrators' responses to other characters' voices--responses that sometimes conflict with and modify one another. At the same time, Collins' contemporary audience's responses to the novel reveal the role of characters' voices in shaping reactions of members of the novel's reading public. Two opposing figures--Laura Fairlie and Count …

And Then, He Folds His Patterned Rug: Repressive Reality And The Eternal Soul In Vladimir Nabokov, Elizabeth Cook

Masters Theses

While Vladimir Nabokov has deservedly earned fame as a stylist of the strange, most critics who study his novels approach his absurd and beautiful characters as little more than fractured victims of a wholly subjective reality. Compounding the misunderstanding is the tired debate over whether or not Lolita is literary, pornographic, or some cruel game of cat-and-mouse in which Nabokov seizes control of his readers' sense of morality. However, critics who read Nabokov as nothing more than a manipulative stylist neglect to realize that his characters suffer such absurd distortions of spirit and mind because their environment--the "average" reality of …

The Acute Responses Of Different-Sized Coronary Arteries To Testosterone, Sampath Madanu

Masters Theses

Coronary arteries supply blood to the myocardium. The blood flow within the coronary arteries is altered by various compounds produced within the body. Sex hormones such as testosterone are known to cause the relaxation of large coronary arteries. But the response to testosterone is greater in in vivo conditions compared to in vitro conditions. We hypothesize that the responses of LADs (left anterior descending arteries) and its side branches to testosterone are heterogeneous and testosterone-induced vasodilation is greater in its side branches. Therefore, our study was designed to determine the effect of testosterone in different-sized coronary arteries. LADs and one …

Automatic Atlas Based Analysis Of Radiotracer Uptake In Bones From Fused Nuclear Imaging/Ct Data Sets Of Mice, Jeffrey Lee Vanoss

Masters Theses

Preclinical in vivo imaging is a powerful tool used for a wide variety of biomedical research applications including oncology, cardiac disease, and neurological disease. Disease physiology can be imaged in vivo with molecular imaging such as PET and SPECT. Quality analysis of molecular in vivo images currently requires an expert technician. The feasibility of large preclinical molecular imaging studies is limited by the man hours required to process the overwhelming amount of data created from preclinical scans. Our proposed solution to the bottle neck of manual image analysis is to implement automation of preclinical molecular image analysis. The method described …

Development Of A Computer-Aided Detection (Cad) Tool For Contrast Micro Computed Tomography Imaging In Diagnosing Liver Metastases, Anderson Steadham Peck

Masters Theses

High morbidity of metastatic tumors in the liver has been observed in several different types of cancers. Liver failure from metastases is one of the primary causes of death in these patients. Effective treatments for liver metastases do not currently exist. However, new pharmaceutical treatments are being explored in a preclinical setting where the cancer and its treatments are designed in vitro and then studied in vivo in mice. Therefore, effective and accurate techniques for non-invasive imaging and analysis of liver metastases in mice are critical to the development of new treatments.

In-vivo micro CT imaging is not only one …

Creating Original Garments Using Couture Sewing Methods, Nicole S. Eckerson

Masters Theses

As part of my research, I examined the techniques and methods used in couture sewing from the past to the present, drawing inspiration from historical couture garments by designers Charles Worth (19th century designer) and Charles James (20th century designer). The four pieces I drew inspiration from include Charles Worth and Bobergh’s evening gown (1861), Charles Frederick Worth’s evening gown (1883), and Charles James’s “Butterfly” ball gown (1954) and “Swan” ball gown (1954). These designers were chosen based on their use of structure and form throughout their pieces. After researching couture sewing methods and using the gowns mentioned above for …

Flutes, Festivities, And Fragmented Tradition: A Study Of The Meaning Of Music In Otavalo, Brenna C. Halpin

Masters Theses

This thesis consists of an intimate study of the value and meaning of flute music of indigenous musicians in the contemporary world. This is accomplished by interviewing and observing indigenous panpipe and flute musicians in and near the Plaza de Ponchos Market in Otavalo, Ecuador. Collected personal stories, historical accounts, and recordings and analysis of the music all provide insight into the purpose and traditions the music holds. While the musicians attempt to maintain a sense of cultural authenticity, modernization has altered the importance of customs and music as Otavalo moves toward a more commoditized and urbanized community, reflecting ethnic …
