Neodymium Isotopic Signature Of The Deep Western Boundary Current And The Distribution Of Neodymium Isotopes And Concentrations Across Line W, Brian Daniel Duggan

Theses and Dissertations

The capacity of the neodymium (Nd) 143Nd/144Nd ratio to trace modern ocean circulation accurately allows for the assumption that the ratio can also accurately trace paleo ocean circulation. Therefore, a complete understanding of Nd cycling and its effect on the isotopic composition in the oceans is vital. Traditionally, Nd isotopic composition (Nd IC) is considered a conservative property in the open ocean, while coastal and margin environments tend to be dictated by nonconservative exchange processes. However, Nd concentrations ([Nd]) in the open ocean typically display a nutrient like profile, increasing with depth. Such a discrepancy between Nd IC and [Nd] …

Saint Dominguan Refugees In Charleston, South Carolina, 1791-1822: Assimilation And Accommodation In A Slave Society, Margaret Wilson Gillikin

Theses and Dissertations

During the 1790s and the first decade of the nineteenth century, nearly 20,000 refugees fled the French colony of Saint Domingue for asylum in the United States. They found new homes in such American port cities as New York, Philadelphia, Baltimore, Charleston, and New Orleans. This dissertation explores the experiences of the white planters, gens de couleur, and slaves who sought asylum in Charleston, South Carolina, and the effect their presence had on the city’s long time residents. It might seem from first glance that finding acceptance in Charleston would be easy for them, but this was not the case. …

Weight-Gain And Energy Balance, Benjamin Thomas Gordon

Theses and Dissertations

Energy balance is the result of a dynamic relationship between energy intake (EI), energy expenditure (EE) and energy storage (ES). These three components of energy balance have extremely complicated associations, and all three major components are consistently influenced by physiologic, psychological, and sociologic factors. Concerted changes between EE and EI result in alterations of the ES. Most often in clinical and research settings, bodyweight is used as marker of body composition (i.e., ES) changes. Traditional measurements of bodyweight do not give an accurate portrayal of ES change or the role it has in energy balance. This dissertation supplies new methods …

Independence At Large: Contemporary China's Alternative Music Scenes And The Cultural Practices Of Post-Socialist Urban Youth, Shan Huang

Theses and Dissertations

Using contemporary Beijing’s alternative music scenes as a focal point, this ethnographic research seeks to enrich the understanding of China’s post-socialist urban youth by examining their cultural practices. First, this thesis offers an analytical account of the popularizing embrace of “independent cultures,” which is defined as a collection of experienceable objects and activities in musical, filmic, theatric, and other cultural forms that are well recognized yet believed by advocates as having aesthetic and participatory features that are different from those produced in the popular culture industry. While the vogue for independent cultures is substantially conditioned by the socioeconomic attributes of …

Who Let The Elephant In The Room? Analyzing Race And Racism Through A Critical Family Literacy Book Club, Lamar L. Johnson

Theses and Dissertations

The purpose of this study was to interpret, investigate, and analyze how race, racism, and power are embedded and intertwined not only in society but also in the education system and in homes and communities. Specifically, through parent and student engagement during a series of book club meetings, I investigated how parents’ racial identities impacted how they created critical dialogue pertaining to issues of race, racism, and power with their children. Guided by critical race pedagogy, critical race theory (CRT) and CRT methodology, this study used race as a critical analytic lens to examine the lives and work of people …

My proposed honors project consists of directing my own, fully-actualized production of Eric Lane’s play Dancing on Checkers’ Grave within the BGSU’s Department of Theatre & Film Elsewhere season. As the director, I must hone in on the play’s relevance to today’s society and shape my storytelling tools to clearly communicate the narrative, establishing a relationship between the performers and the audience.

Dancing on Checkers’ Grave is a play about two very different teenage girls who come to bond over homework, “munchkining,” relationships, and nail polish. Rooted within the text are topics of sexual identity, what it means to be …

When Life Happens: Theatres Of Hiv And Complexity In South Africa, Jessica S. Ruthven

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation examines theatre as part of an artistic movement in South Africa to address the social, structural, and emotional repercussions of HIV, as well as a space in which knowledge about HIV/AIDS is actively created, mediated, reproduced, challenged, and presented for public consumption. Although applied theatre has a long history in the country, I focus on innovation in recent theatrical practices that have occurred as artists and members of broader civil society struggle to understand the trajectory of the country's AIDS epidemic and question the scope of popular national HIV intervention campaigns. I use emerging forms of cultural production …

Evolution Of Ecological Dominance Of Yeast Species In High-Sugar Environments, Kathryn Marie Williams

Arts & Sciences Graduate Student Theses and Dissertations

Two challenging goals of evolutionary biology are to understand how evolutionary innovations evolve and how they contribute to the success of lineages. Evolutionary innovations may arise following whole genome duplication (WGD) events and they are suspected to contribute to the success of lineages by creating ecological opportunity. However, direct evidence for duplicated genes involved in evolutionary innovations remains rare, and the relationship between evolutionary innovations and the success of lineages may be very complex. In this study, I explore the relationship of evolutionary innovation, WGD, and the ecological dominance of yeast species in high-sugar environments. In budding yeast, a major …

Feeling Doctrine: Religious Meanings Of Emotion In Sixteenth-Century German Literature, Georgia Anna Leeper

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation explores the intersections of emotion and Protestant theology in late-16th-century German literature. The project demonstrates the availability of even secular texts to confessional readings through the analysis of representations of emotions. Post-Reformation texts practice an emotional exemplarity that highlights the effects - including the spiritual effects - which emotional experiences have on the individual. I argue that narrative representations of emotions at this moment reflect anxieties about the nebulous nature of faith, and its central role in Protestant salvation. Close readings of widely-read texts such as the 1587 Faustbuch, Melusine, and Hans Sach's Judith: ein Comedi, among others …

Applications Of Nonlinear Optimization, Yao Xie

Arts & Sciences Graduate Student Theses and Dissertations

We apply an interior point algorithm to two nonlinear optimization problems and achieve improved results. We also devise an approximate convex functional alternative for use in one of the problems and estimate its accuracy. The first problem is maximum variance unfolding in machine learning. The traditional method to solve this problem is to convert it to a semi-definite optimization problem by defining a kernel matrix. We obtain better unfolding and higher speeds with the interior point algorithm on the original non-convex problem for data with less than 10,000 points. The second problem is a multi-objective dose optimization for intensity modulated …

Bio-Enhanced Constructivism: Moral Facts For The Naturalistic But Morally Serious Philosopher, Jason Gardner

Arts & Sciences Graduate Student Theses and Dissertations

ABSTRACTBio-Enhanced Constructivism: Moral Facts for the Naturalistic but Morally Serious PhilosopherbyJason GardnerDoctor of Philosophy in PhilosophyWashington University in St. Louis, 2014Professor Eric Brown, ChairThere is a tension between being both morally and naturalistically serious because it is doubtful that features philosophers have ascribed to moral facts in order to explain why we should take them seriously can be given a naturalistic accounting. Yet even serious naturalists who think the tension is real and troubling persist in trying to be serious moralists. I do not think they can do so on their own terms. Thus the purpose of this dissertation: to …

Comparison Of Conventional And Bayesian Analysis For The Ultrasonic Characterization Of Cancellous Bone, Amber Groopman

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation investigates the physics underlying the propagation of ultrasonic waves in cancellous bone. Although quantitative ultrasound has the potential to evaluate bone quality even better than the current gold standard X-ray based modality, its clinical utility has been hampered by the incomplete understanding of the mechanisms governing the interaction between ultrasound and bone. Therefore, studies that extend the understanding of the fundamental physics of the relationship between ultrasound and trabecular bone tissue may result in improved clinical capabilities.Ultrasonic measurements were carried out on excised human calcaneal specimens in order to study the effects of overlapping fast and slow compressional …

The Automatic And Controlled Influence Of Environmental Cues During Recognition Judgments, Diana Selmeczy

Arts & Sciences Graduate Student Theses and Dissertations

Recognition judgments are often made in the context of environmental information, such as instructions or payout regimens that observers have been shown to use in order to adaptively bias their memory judgments. These adaptive biases are usually characterized as a strategic, controlled process that observers adopt intentionally, and this is formalized in signal detection theory wherein strategic criterion placement is assumed fully independent of recognition evidence signals. However, recent pilot research in our laboratory suggests that the ability to regulate recognition decision biases in the context of environmental cues may not be fully controlled by observers suggesting an automatic or …

Context-Sensitive Seismic Strengthening And Repair Of Substandard Confined Masonry, Rahim Ghorbani

Theses and Dissertations

Confined masonry (CM) is a construction system consisting of load-bearing masonry panels that are confined with cast-in-place reinforced concrete tie columns and beams. Due to satisfactory seismic performance, CM has become the predominant low-rise residential construction system in several areas around the world. However, in developing regions, the use of substandard materials, details and construction practices may result in inadequate performance as highlighted in the 2010 earthquakes in Haiti and Chile. In the aftermath of an earthquake, households are often reluctant to reoccupy their dwellings due to concerns about safety of structures. If feasible, preventive (pre-hazard) strengthening or structural repair …

Making Fun Of Franco: Representations And Caricatures Of Spanish Fascism In The Films El Espiritú De La Colmena, Cría Cueros And El Laberinto Del Fauno, Elizabeth Pruchnicki

Renée Crown University Honors Thesis Projects - All

The end of the Spanish Civil War marked the beginning of Francisco Franco’s dictatorship, which lasted more than 35 years. Throughout this time, he systemized terror, executing more than 100,000 republican sympathizers in the first few years of his regime and marginalizing the remainder of the population. Therefore, the Fascist Era lasting from 1940-1975 is one plagued with strained relationships, ambiguous loyalties and distant relatives. The films El espiritú de la colmena by Victor Erice, Cría cuervos by Carlos Saura and El laberinto del fauno by Guillermo del Toro’s illustrate these kinds of challenges, from the point …

Penn State Football: An Analysis Of Crisis Communication Best Practices And How Psu Overcame The Ultimate Pr Crisis, Meaghan Grace Lane

Renée Crown University Honors Thesis Projects - All

This thesis paper is an analysis of the crisis communication response to the 2011 Pennsylvania State University child sex abuse scandal. The reputation of this iconic university and its football program was changed forever by this horrific event, which involved years of administrative cover-ups of the sexual assault of children by an assistant football coach. However, despite widespread public backlash, administrative upheaval and heavy NCAA sanctions in the months after the scandal broke, Penn State has since made major strides in image improvement.

This project delves into what defines best crisis communication practices, using Penn State as a case study. …

Origin Of Maternal Age Effect In Congenital Heart Disease Risk For Offspring, Claire Elaine Schulkey

Arts & Sciences Graduate Student Theses and Dissertations

Increasing maternal age is widely acknowledged to lead to greater likelihood of pregnancy complications and congenital abnormalities, but the basis of this effect has not been well studied. Often dismissed as the product of oocyte ageing, the mechanistic basis of this maternal age effect is likely more complex.Congenital heart disease is a classic complex disease with multiple genetic and environmental modifiers, including maternal age. Maternal ageing is a known risk-factor in humans, and has been shown to exist in an Nkx2-5 haploinsufficient mouse model for the disease. This mouse model's maternal age risk is dependent upon strain background, with C57BL/6N …

Synthesis And Characterization Of Pbs Quantum Sheets Through Lamellar Assembly, And Updates To The Cdse Quantum Wire Synthesis, Paul James Morrison

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation reports the novel synthesis of PbS quantum plates (QPs) via a reaction executed at low temperatures. The PbS QPs are grown in a template-assisted mechanism, with the first excitonic peak observed in the visible region of light at ~620 nm (2.0 eV), at an energy radically different than the band gap of bulk PbS (~3000 nm, 0.42eV). The large energy shift is due to the extremely thin dimension of these nanoplates, which is determined to be ~1 nm in thickness. Thickness measurements are made in a powder X-ray diffractometer (XRD) at low angles (between 2-15º 2θ). These measurements …

If available, these isotopes would be of interest to a broad range of applications such as medicine, geology, and stockpile stewardship. Preliminary experiments were performed at the NSCL in order to determine the feasibility of isotope harvesting at (FRIB).A water target station that consisted of a …

Characterizing The Fitness Landscapes Of Gut Symbionts In Defined Community And Diet Contexts, Meng Wu

Arts & Sciences Graduate Student Theses and Dissertations

A species' niche is the description of all the environmental conditions required to permit a population of that species to persist, including the effects of the population on those conditions. This definition includes the species' resource requirements, as well as stress tolerances and interactions with other species acting as competitors, predators, parasites, and mutualists. The human gut microbiota serves as a microbial `metabolic organ' tasked in part with the biotransformation of many components of our diet. Relatively little is known about the factors that allow members of the human gut microbiota to persist in a habitat that experiences marked changes …

The Impact Of Documentation Status On The Educational Attainment Experiences Of Undocumented Hispanic/Latino Students, Brittanie Alexandria Roberts

Dissertations and Theses

The issue of undocumented immigration has recently taken center-stage in the media and national politics in the United States. A large population of undocumented youth grows up with legal access to public education through high school, following the Supreme Court decision of Plyler vs. Doe, but faces legal and economic barriers to post-secondary education. Following high school, undocumented Hispanic/Latino youth legal protections end, greatly limiting chances for upward mobility through traditional post-secondary education pipelines. In some cases, knowledge of future barriers to post-secondary education leads to a decline in educational motivation.

The current political atmosphere makes this study a bit …

Elaborating Patient Agency In Breast-Cancer Care: A Grounded Theoretical Analysis Of Patients Asserting Treatment Preferences, Rachel Sofia Erdman

Dissertations and Theses

Successful physician-patient communication is increasingly being acknowledged as a vital aspect of healthcare today. Research in the field has not examined all aspects of patient-centered care and the aspects that have been studied have not been grounded in actual patient action. The research done in the field has largely been studied quantitatively. The present thesis research attempts to contribute to the gap in the field of physician-patient communication by qualitatively examining patient assertiveness. This thesis examines conversations between women in Portland, Oregon recently diagnosed with breast cancer talking to their surgeons about their diagnoses and treatment options. Using grounded qualitative …

An Essential Role For Self-Pmhc Throughout The Life Of A Cd4 T Cell: Contributions In The Thymus And Periphery, Stephanie Rodriguez

Arts & Sciences Graduate Student Theses and Dissertations

It is well established that self-peptide Major Histocompatibility Complexes (hereafter self-pMHC) are essential for the development of a broad repertoire of mature, self-tolerant CD4 and CD8 T cells. Despite clear knowledge that the pool of self-ligands is critical for positive and negative selection, the exact kinetics and dynamic nature of thymocyte interaction with self-pMHC class II (self-pMHCII) bearing antigen-presenting cells (APCs) during development is still largely a mystery. The enigmatic nature of selecting self-pMHC is not unique to the thymic environment; increasingly evident is the dependence of peripheral T cells on extra-thymic self-pMHC expression, specifically selecting self-pMHC, for their homeostatic …
