Surface Complexation Modeling Of Cr(Vi) Absorption On Mineral Assemblages, Ann M. Gilchrist

Masters Theses

Hexavalent chromium (Cr(VI)) is a waste product of many anthropogenic processes. Because it is highly mobile, the improper disposal of Cr(VI) has caused widespread contamination. Because reduction and adsorption reactions may reduce the bioavailability and mobility of Cr(VI) in environmental systems, a better understanding of Cr(VI) adsorption behavior will improve remediation efforts.

Subsurfaces and soils are heterogeneous, however most studies focus on single sorbate/sorbent interactions to develop surface complexation models (SCM) for prediction of heavy metal adsorption. Theoretically, combining the SCMsdeveloped for single sorbate/sorbent systems should yield accurate predictions of adsorption in more complex systems (i.e., the component additivity approach …

An Examination Of The Long Term Effects Of Exposure To Prescription Drugs On Infant Growth And Development, Annalisa Maurer

Masters Theses

The effects of prenatal exposure to many prescription medications are well known. However, little is known about the long term side effects early exposure to medications used to treat pain and sedate have on growth and development. This paper explores the long-term effects of postnatal exposure to prescription medication. The potential effects are applied to physical, cognitive, and social-emotional development as well as the overall health of an infant. Additionally, the options of the use of commonly used analgesics and sedatives are compared to other pain management options. Research surrounding long-term effects of early exposure to pain and generalizations/recommendations are …

A Preliminary Study Of The Articulatory And Acoustic Features Of Forward And Backward Tone Placement In Singing, Krista Wyllys

Masters Theses

A variety of terms exist for describing tone quality in singing, and voice scientists, voice therapists, teachers of singing, and students of singing use different terms to describe the same sound. One aspect of tone quality is tone placement. Teachers of singing often rely on imagery and imitation to elicit correct tone placement from students of singing. More concrete data about what produces forward and backward tone placement could supplement singing teachers’ current practice of using imagery and imitation to elicit a desirable tone quality. This study examined forward and backward tone placement to determine the articulatory gestures and acoustic …

A Quantitative Analysis Of Collegiate Athletic Involvement And Academic Achievement Among Sport Management Students, Christopher Amos

Masters Theses

Within the last several decades, more attention has been focused on the academic success of college athletes. It has been documented from several studies that high school athletes perform better academically than their non-athlete peers (American Sports Institute, 1995; Brand, 2007; Dilley-Knoles, Burnett, & Peak, 2010; Foltz, 1992; Fox, Barr-Anderson, Neumark-Sztainer, & Wall, 2010; Slear, 2005). However, at the collegiate level, this heightened academic achievement trend among student-athletes is not so clear. Lapchick often releases data regarding graduation rates among a select group of highly achieving teams in certain sports but not much exists in the way of a comparison …

The first experiment compared the efficacy of adding multiple in-street signs used in a gateway configuration with a single sign between the two travel lanes in each direction. The second experiment compared the in-street sign gateway treatment …

Expression Of The Chemokine Receptor, Cxcr4, And Its Ligand, Sdf-1, Are Increased In Purkinje Cells Of The Multiple System Atrophy Cerebellum, Megan Welter

Masters Theses

Multiple System Atrophy (MSA) is a sporadic, neurodegenerative disease that consists of three conditions: autonomic dysfunction, Parkinsonism and cerebellar ataxia. Our lab conducted an Affymetrix global gene expression analysis using pons tissue of MSA patients to determine genes that are differentially expressed when compared to non- MSA controls. This study identified upregulated genes, including the C-X-C chemokine receptor type 4, CXCR4, to which stromal cell-derived factor-I (SDF-1) is the natural ligand. The CXCR4/SDF-1 signaling pair has been sho.wn to play multiple roles in the brain, such as inducing neuronal apoptosis and promoting leukocyte recruitment during inflammation. The MSA cerebellum presents …

Executive Functions And Social Interactions: Developing Social Scenarios, Mackenzie Waite

Masters Theses

The aim of this study was to develop a series of vignettes to form the basis for an assessment of executive functions (EFs) for 9 – 12 year old children. Although EFs are necessary for effective social communication and positive social interactions, currently, most EF assessments focus on impersonal activities. Little research exists that incorporates real-time processing using ecologically valid social scenarios. The current study aims to develop realistic scenarios that children could encounter in daily life. Ethnographic interviews were conducted with six participants, who worked in a school with 9-12 year old children, to gain their perspective on social …

Explicit Teacher-Implemented Phoneme Awareness Instruction: Preschool Effects, Heather M. Osterhouse

Masters Theses

The purpose of the current study was to investigate the impact of explicit, concentrated, teacher-implemented phonological awareness instruction for ―at risk‖ 4- year-olds. Early childhood educators were trained to implement a 10-week program delivered for 20-minute sessions, four times a week, in their classrooms. The program focused on phonological awareness beginning at the level of letter-sound knowledge and advancing to blending and segmenting constituent phonemes in words. Pre- to post-treatment comparisons of phonological awareness and letter knowledge skills indicated that children in the experimental group made significant gains in comparison to the control group in phoneme blending and letter knowledge. …

This study presents and alternative approach to how pregnancy is interpreted in western society and how settings such as a pregnancy center both challenges and reinforces these social standards. The promotion of abstinence, the aversion to abortion, notions of truth and morality, religious narratives, and the standard of care are all integral components to this analysis of pregnancy, language, and culture.

The Effectiveness Of The New Town Policy In Managing Growth And Congestion In Mega Cities: A Case Study Of Lagos, Nigeria New Town Policy, Abolaji Samson Olanipekun

Masters Theses

One of the major challenges facing municipal governments of megacities in developing countries is shortage of urban infrastructures relative to population growth. Because cities play important role in the economic development of every nation, problems confronting them require proactive policy measures by the government. One such mega city is Lagos, Nigeria. From 1962 to 2006, the population of Lagos grew from 1,135,805 to 17.5 million. Crammed on a 2200 square kilometer land area of which 18.9%, Lagos population is projected to reach 20.5 million by 2015, an explosion largely driven by the non-regulatory internal migration system. The result of this …

Use Of A Specific Alpha7 Nicotinic Acetylcholine Receptor Agonist Can Prevent Loss Of Retinal Ganglion Cells In An In Vivo Rat Glaucoma Model, David Mata

Masters Theses

Acetylcholine (ACh) has been shown to have a neuroprotective effect against glutamate-induced excitotoxicity in cultured retinal ganglion cells (RGCs) through activation of α7 nicotinic ACh receptors (nAChRs). In this study, the neuroprotective effects of the α7 nAChR agonist, PNU-282987, were investigated using an in vivo model of glaucoma in adult Long Evans rats. Hypertonic saline injections were used to induce a glaucoma model. After one month, retinas were removed, flat mounted, fixed and labeled with an antibody against Thy 1.1 to label RGCs and fluorescently tagged for visualization. Eye drop application of PNU-282987 resulted in neuroprotection against RGC loss in …

No Greater Love: Recognition, Transformation, And Friendship In The Harry Potter Series, Stephen Parish

Masters Theses

Nobody today doubts the momentous influence the Harry Potter series has had on a generation of readers. Many scholars and critics assume Harry's place amongst other great works of children's literature, and indeed the series has brought about a revival in children's literature scholarship. Despite this popularity, many critics question the series' aesthetics, its attention to moral demeanor. Therefore, what element exists in Harry Potter that could enforce its aesthetic quality? Based on a rhetorical reading of the texts, my thesis upholds the aesthetic nature of the books through an analysis of the trio's friendship and and its impact on …

Life Inside The Spectacle: David Foster Wallace, George Saunders, And Storytelling In The Age Of Entertainment, John Hawkins

Masters Theses

This project explores George Saunders's In Persuasion Nation and David Foster Wallace's Infinite Jest as interventionary literature. The thesis asserts that the two works confront the problems of isolation and dehumanization created by entertainment-based consumerism; they do so by depicting satirically exaggerated consumer societies and placing well-developed, sympathetic characters in those settings. The thesis includes a consideration of Jameson and deBord's theories of spectacle and Wallace's stated concerns with postmodern irony as an ineffective form of critique.

Putting Down Roots: A Tolkienian Conception Of Place, Kayla Snow

Masters Theses

This thesis explores the way in which J.R.R. Tolkien's develops and expresses his nuanced sense of place through his major literary works--namely, The Silmarillion, The Hobbit, and The Lord of the Rings trilogy. Tolkien's sense of place, as expressed through his fiction, encompasses both metaphysical and geographical relational structures that are operative at both the local and global levels. As Tolkien develops his sense of place in his fiction, he draws from the Distributist principles--largely informed by Catholic social policy of the late nineteenth century and popularized by G.K. Chesterton--to build the economy in Middle-earth. The resulting economy resists industrialization …

Spice Sisters: Religion, Freedom And Escape Of Women In African American And Indian Literatures, Lovely Koshy

Masters Theses

This thesis focuses on women in Lorraine Hansberry's A Raisin in the Sun and Rabindranath Tagore's three short stories. Hansberry writes during a period in America when racism, segregation, and black migration to the North weighed heavy upon the psyche of black women. Tagore writes during a time when British control, sati system, caste system, and dharma leave Indian women voiceless. Both express their disagreement with entrenched norms and institutions that have been in place for hundreds of years, a task that initially may seem to be an impossible undertaking, and unlikely to bring about expected change. This work reveals …

Women As Victims In Tennessee Williams' First Three Major Plays, Ruth Foley

Masters Theses

Although Tennessee Williams does not openly champion the rights of women in his plays, he presents strong cases against their social alienation in a harsh and brutal world governed by men. Williams' emotional leanings, sensitivity, and intuition enable him to see life through women's eyes. In The Glass Menagerie, A Streetcar Named Desire, and Summer and Smoke, Williams astutely sounds the battle cry for women to fight against male oppression. He shows how Amanda Wingfield, Laura Wingfield, Blanche Dubois, Stella Kowalski, and Alma Winemiller are held hostage to the rules governing patriarchal society and become unhappy marginalized victims. The self-contained …

Disease, War, And Famine In The Sudan And Haiti: A Crisis Noticed And A Crisis Ignored, Melissa Whalen

Masters Theses

The media acts as a gatekeeper and decides what material to cover and what not to cover. In order to better understand why one disaster receives media coverage and another crisis is virtually unnoticed by the media, the motives behind covering one story over another is analyzed in this study. Three major American newspaper articles concerning the Haitian earthquake and the crisis in Darfur are examined in order to discover the media's motives for covering Haiti over Darfur.

The Story Of Your Life On A Single Page: Assessing The Narrative Coherence Of Life Storytelling Through Facebook's Timeline Profile Design, Joseph Marcus

Masters Theses

Facebook's transition to the Timeline profile design brought with it a new focus: Life storytelling. Walther Fisher posited the narrative paradigm as a way of understanding all communication in the form of stories. The paradigmatic component of coherence assesses the structural integrity of a narrative, the characters, and the encompassing themes found within. This study applies narrative coherence to the Timeline profile design to assess the coherence of life narratives told through individuals' Facebook Timelines. The researcher observed the Timeline profiles of 15 participants on the basis of three research questions. The researcher's observation yielded data suggesting that life narratives …

Charles Dickens' Great Expectations: The Failed Redeemers And The Fate Of The Orphan, Rebekah Overbey

Masters Theses

The figure of the orphan is scattered throughout the pages of Victorian novels, though few novelists created orphans that were quite as memorable as Charles Dickens. Lonely orphans and abused children appear in nearly all of Dickens' fictional works; in the novels in which the orphan is the main character, this innocent, helpless orphan is often adopted by a wealthy and benevolent benefactor, and the orphan is thus redeemed by a dramatic rescue. In Great Expectations, however, Dickens inverts this redemption by rescue that was so characteristic of his earlier novels. Instead of an innocent, helpless child, Great Expectations has …

Using Behavioral Interventions Amongst Unionized Workers To Increase Attendance, Marlies Hagge

Masters Theses

Employees’ attendance is fundamentally relevant for running a successful business. However, in many companies absences far exceed the national average of about 3% and pose a significant problem to the company’s overall success. This study compares the effectiveness of different low-cost behavioral interventions in order to increase attendance and specifically decrease the amount of avoidable absences from 6.3% overall absenteeism during baseline. Participants include 45 unionized custodians in 6 groups at a large Midwestern university. Interventions were introduced for 4 of the groups while the remaining 2 groups served as a control. Treatments evaluated include public recognition for perfect attendance, …

Victim Of A Revolution: Nicholas Cresswell's American Odyssey, 1774-1777, Matthew Exline

Cresswell's travels took him from the eastern seaboard (and Barbados) to Kentucky and Ohio, and from Williamsburg, Virginia to New York City. The people he met encompassed almost the entire political spectrum of the day, ranging from William Howe and Loyalist operatives such as John Connolly to grassroots patriot activists on the Committees of Public Safety and founding luminaries such as George Rogers Clark, Thomas Jefferson, and Patrick Henry. He rubbed shoulders with people from …

The Internet And Mass Society: Civic Engagement In The Digital Age, Simon J. Purdy

Masters Theses

In this study, the relationship between Internet use and civic engagement is examined. Building off of the work of previous researchers, which has found no clear relationship between Internet use and civic engagement, this analysis attempts to find differences between those who are civically engaged at different levels, in terms of Internet use, types of civic engagement and feelings of being able to affect change through civic engagement. Several hypotheses about this relationship are tested using data collected from undergraduate students at a medium sized Midwestern university with an online survey method. The statistical analysis entails building a series of …

Isolation Of A Dosage Dependent Suppressor Using Saccharomyces Cerevisiae As A Model System, Rachel Chimner

Masters Theses

Human pathogenic Yersinia use a type three secretion system to deliver various effector proteins into host cells. Once these effector proteins are within the cell, they elicit a cascade of events that disrupt the normal immune response. One of these effectors, YopT, is known to disrupt actin distribution but it is currently unknown what YopT targets within the host cell. To investigate the cellular targets of the YopT effector, we use a yeast model system and a dosage-dependent suppression screen. The dosage-dependent suppression screen isolated three plasmids able to suppress YopT induced lethality within yeast. One of them, 2T9, was …

Investigation Of The Closing Forces Involved In Re-Approximation Of The Renal Remnant Following Partial Nephrectomy, Donald M. Endres Ii

Masters Theses

Partial nephrectomy has become the preferred method of treatment in certain renal diseases, including small, peripheral tumors. However, re-establishment of hemostasis in the remaining tissue remains a challenging procedure. To better understand the forces involved in re-approximation of the renal remnant, this study measures the suture tensions reached in sliding clip renorrhaphy, as well as the ability of the tissue to support those tensions, and reviews how long suture material might be expected to survive those forces.

Three separate groups of experiments were conducted on fresh, porcine kidney tissue. Treatment groups were compared using commercially available software to compute appropriate …

The Role Of Extracellular Matrix Proteins On Epithelial To Mesenchymal Transition In Glioblastoma Multiforme, Stephen C. Orey

Masters Theses

Glioblastoma multiforme (GBM) is the most common primary brain tumor in humans and is characterized as being highly aggressive and invasive, with the ability to locally invade different areas of the central nervous system (CNS). GBM local invasion undergoes an epithelial to mesenchmal like (EMT) process characterized by the loss of cell-cell adhesion and increased cell mobility. The EMT-like switch in GBM is triggered by a single transcription factor, Twist1, and is characterized by the loss of cell clustering, re-organization of the basement membrane, and increased cell migration. GBM invasion depends on the remodeling of the extracellular matrix (ECM) …

Missing The Mark: Why Modern Efforts To Better Schools Through Standardization Aren't Working, Richard Knowlton

Masters Theses

In the thirty years of school reform that began with A Nation at Risk, and continues today with A Race to the Top, the United States has rapidly increased its reliance on a standardized “one-size-fits-all” policy in regard to modern educational reform. This report provides a review of the empirical and statistical evidence to demonstrate that despite lofty and well-meaning intentions, modern reform has done nothing to significantly advance the quality of education in America, and in many cases have had a severe negative impact—blocking real reform. Many schools, especially those in low-income areas, have become glorified test-prep centers in …
