Capture And Release Gels For Optimized Storage (Cargos), Theodore S. Kalbfleisch Ii

Electronic Theses and Dissertations

Unassisted, the lifetime of many proteins outside their natural environment is very short. Scientists generally need to extract the sample, often in remote locations, and then transport, isolate, and store such biospecimens relatively far from the point of origin in order to study them. Currently, the most commonly used methods for storage of biospecimens are cryopreservation or refrigeration which, though effective, have their fair share of flaws. Cryopreservation and refrigeration-based storage of biospecimens requires a great deal of space and other resources to be effective. Furthermore, the hardware required for cold storage does not transport well. These factors make such …

Investigation Of Flexural Behavior Of Steel Fiber Reinforced Concrete And Steel Fiber Orientation Control During Construction, Maria Kolisnichenko

Electronic Theses and Dissertations

Concrete is the most widely used construction material in the world, and its consumption has been increasing. The main benefits of concrete include its durability, availability of the components, and great strength in compression. Despite all these advantages, however, concrete is a brittle material with a relatively low tensile strength and deformation capacity. It is, therefore, vulnerable to cracking under tension, which can lead to sudden catastrophic failures of concrete structures. In order to control and reduce cracking, reinforcement of concrete is necessary.

The most commonly used reinforcement technique in structural application is the use of deformed steel bars. However, …

When Process Becomes Processing: Managing Instructor Response To Student Disclosure Of Trauma In The Composition Classroom, Kelci Barton

Electronic Theses and Dissertations

In first-year composition courses, there are three aspects of teaching that are researched well so far: disclosure of trauma in student writing, instructor feedback, and emotional labor. The disclosure of trauma is almost completely unavoidable in first-year composition. We encounter an issue with instructor feedback; how do we provide feedback to student writing, like grammar and mechanics, when the student has disclosed trauma in the writing? Additionally, we can build off this with emotional labor, which already occurs consistently in teaching but is heightened in this instance. When providing feedback to a student who has disclosed trauma, this can be …

Pocket Ace: Neglect Of Child Sexual Abuse Survivors In The Aces Study Questionnaire, Robyn Dolson

Electronic Theses and Dissertations

In 1998, a seminal study on adverse childhood experiences (ACEs) and subsequent health risks catapulted ACEs and the study questionnaire into the zeitgeist. However, its childhood sexual abuse (CSA) item is problematic as it requires the perpetrator have been 5-years or older than the victim. To assess whether some survivors’ CSA is not identified by the current item, whether their exclusion prevents access to services requiring a four-threshold ACE score, and how their health outcomes compared to other CSA groups and controls, an international sample of 974 women completed an online survey assessing their current health and CSA history using …

A Systematic Assessment Of Socio-Economic Impacts Of Prolonged Episodic Volcano Crises, Justin Peers

Electronic Theses and Dissertations

Uncertainty surrounding volcanic activity can lead to socio-economic crises with or without an eruption as demonstrated by the post-1978 response to unrest of Long Valley Caldera (LVC), CA. Extensive research in physical sciences provides a foundation on which to assess direct impacts of hazards, but fewer resources have been dedicated towards understanding human responses to volcanic risk. To evaluate natural hazard risk issues at LVC, a multi-hazard, mail-based, household survey was conducted to compare perceptions of volcanic, seismic, and wildfire hazards. Impacts of volcanic activity on housing prices and businesses were examined at the county-level for three volcanoes with a …

The Rhetoric Of Camp: Adam Lambert's Identification And Division Strategies In His American Idol Performances, Isabelle Lanthier

Electronic Theses and Dissertations

This study analyzes camp style as a rhetorical strategy for Burkean rhetorical identification. Through a case study of Adam Lambert's use of this style on American Idol in 2009, this study produced a rhetorical theory of camp that challenges the typically dialectical relationship between identification and its opposite: division. This study responds both to Susan Sontag's seminal essay on camp style and to other conversations surrounding identification, which revolve around how rhetors avoid division (Borrowman and Kmetz; Jones and Rowland), how rhetors appeal to conflicting audiences (DeGenaro; Helmbrecht and Love), how rhetors create new narratives as a means of identification …

Judaism, often existing in an in between place with outward characteristics that reflect regional influences, facilitates a dialogue about whether there are relative or absolute delineations within and between …

Hybridity And Political Disorder : A Mixed Method Approach To Understanding The Hybrid Regime., Bryce Jamison Kleinsteuber

Electronic Theses and Dissertations

This thesis focuses on two central questions; first, does regime hybridity lead to an increased propensity for political disorder; and second, what specific regime level characteristics are responsible for the increased propensity. The theoretical basis for this study is founded in the understanding that the duality of Hybrid regimes ensures that they receive neither the benefit of Authoritarian, coercive force nor Democratic plasticity and thus are unable to prevent political disorder. Therefore, during periods of political transition leaders in these regimes not only cannot prevent these events but may be incentivized to allow or even encourage certain events as a …

This study utilized a large database of lower tooth lengths and ratios in an attempt to differentiate black and brown bears in North America. Further, this project examined how these linear measurements differ geographically. Analysis of variance (ANOVA) found significant differences between black and brown bears from across North America for every variable studied. Stepwise discriminant analyses (DA) …

"We Germans Fear God, And Nothing Else In The World!" Military Policy In Wilhelmine Germany, 1890-1914, Cavender Sutton

Electronic Theses and Dissertations

Throughout the Second Reich’s short life, military affairs were synonymous with those of the state. Indeed, it was the zeal and blood of Prussian soldiers that allowed the creation of a unified German empire. After solidifying itself as a major power, things grew more complicated as the Reich found itself increasingly surrounded by hostile rivals. To the west, French humiliation over their catastrophic defeat in 1870-71 continued to fester while, in the east, Russian sympathies for the new empire waned. The finalization of a Franco-Russian alliance in 1894 meant Germany faced formidable adversaries along her eastern and western borders. That …

Comparison Of Imputation Methods For Mixed Data Missing At Random, Kaitlyn Heidt

Electronic Theses and Dissertations

A statistician's job is to produce statistical models. When these models are precise and unbiased, we can relate them to new data appropriately. However, when data sets have missing values, assumptions to statistical methods are violated and produce biased results. The statistician's objective is to implement methods that produce unbiased and accurate results. Research in missing data is becoming popular as modern methods that produce unbiased and accurate results are emerging, such as MICE in R, a statistical software. Using real data, we compare four common imputation methods, in the MICE package in R, at different levels of missingness. The …

Generalizations Of The Arcsine Distribution, Rebecca Rasnick

Electronic Theses and Dissertations

The arcsine distribution looks at the fraction of time one player is winning in a fair coin toss game and has been studied for over a hundred years. There has been little further work on how the distribution changes when the coin tosses are not fair or when a player has already won the initial coin tosses or, equivalently, starts with a lead. This thesis will first cover a proof of the arcsine distribution. Then, we explore how the distribution changes when the coin the is unfair. Finally, we will explore the distribution when one person has won the first …
