Key Factors Influencing Retention Rates among Historically Underrepresented Student Groups in STEM Fields

Description: The aim of the study was to identify the factors that have an influence on the completion rates of undergraduate students in the fields of science, technology, engineering and mathematics (STEM). Using Tinto's retention rate theory as the theoretical foundation, data were collected from freshman who were enrolled in the years 2005 to 2008. Results showed gender and first-generation status were significant predictors of STEM completion and time taken to complete the degree. Institutional bias pl… more

Information Content of Non-GAAP Earnings of Cross-Listed Companies

Description: To supplement earnings reported under generally accepted accounting principles (GAAP), public companies often voluntarily report alternative measures of earnings called non-GAAP earnings (NGE). These companies assert that NGE exclude the effect of non-recurring transactions, thereby helping users of financial information to better assess the company's past performance and prospects. Because NGE measures are not well defined, managers can exploit the inherent discretion in calculating NGE to mis… more

Fence, Flavor, and Phantasm: Balancing Japanese Musical Elements and Western Influence within an Historical and Cultural Context

Description: Given the diversity found in today's Japanese culture and the size of the country's population, it is easy to see why the understanding of Japanese wind band repertoire must be multi-faceted. Alongside Western elements, many Japanese composers have intentionally sought to maintain their cultural identity through the addition of Japanese musical elements or concepts. These added elements provide a historical and cultural context from which to frame a composition or, in some cases, a composer's c… more

Using the Abraham Solvation Parameter Model to Predict Solute Transfer into Various Mono- and Multi-Functional Organic Solvents

Description: The Abraham Solvation Parameter Model (ASPM) is a linear, free-energy relationship that can be used to predict various solute properties based on solute-solvent interactions. The ASPM has been used to predict log (K or Cs,organic/Cs,gas) values, as well as log (P or Cs,organic/Cs,water) values for solute transfer into the following organic solvents: 2-methoxyethanol, 2-ethoxyethanol, 2-propoxyethanol, 2-isopropoxyethanol and 2-butoxyethanol. The derived log (K or Cs,organic/Cs,gas) correlations… more

Computational Investigation of DNA Repair Enzymes: Determination and Characterization of Cancer Biomarkers and Structural Features

Description: Genomic integrity is important for living cells' correct functioning and propagation. Deoxyribonucleic acid as a molecule is a subject to chemical reactions with agents that can come from environment as well as from internal metabolism processes. These reactions can induce damage to DNA and thus compromise the genetic information, and result in disease and death of an organism. To mitigate the damage to DNA, cells have evolved to have multiple DNA repair pathways. Presented here is a computat… more

Validation and Evaluation of Emergency Response Plans through Agent-Based Modeling and Simulation

Description: Biological emergency response planning plays a critical role in protecting the public from possible devastating results of sudden disease outbreaks. These plans describe the distribution of medical countermeasures across a region using limited resources within a restricted time window. Thus, the ability to determine that such a plan will be feasible, i.e. successfully provide service to affected populations within the time limit, is crucial. Many of the current efforts to validate plans are in … more

Non-Resonant Uniserial Representations of Vec(R)

Description: The non-resonant bounded uniserial representations of Vec(R) form a certain class of extensions composed of tensor density modules, all of whose subquotients are indecomposable. The problem of classifying the extensions with a given composition series is reduced via cohomological methods to computing the solution of a certain system of polynomial equations in several variables derived from the cup equations for the extension. Using this method, we classify all non-resonant bounded uniserial ext… more

Uniserial Representations of Vec(R) with a Single Casimir Eigenvalue

Description: In 1980 Feigin and Fuchs classified the length 2 bounded representations of Vec(R), the Lie algebra of polynomial vector fields on the line, as a result of their work on the cohomology of Vec(R). This dissertation is concerned mainly with the uniserial (completely indecomposable) representations of Vec(R) with a single Casimir eigenvalue and weights bounded below. Such representations are composed of irreducible representations with semisimple Euler operator action, bounded weight space dimensi… more

Alloy Development and High-Energy X-Ray Diffraction Studies of NiTiZr and NiTiHf High Temperature Shape Memory Alloys

Description: NiTi-based shape memory alloys (SMAs) offer a good combination of high-strength, ductility, corrosion resistance, and biocompatibility that has served them well and attracted the attention of many researchers and industries. The alloys unique thermo-mechanical ability to recover their initial shape after relatively large deformations by heating or upon unloading due to a characteristic reversible phase transformation makes them useful as damping devices, solid state actuators, couplings, etc. H… more

Access to Health Care and Rates of Mortality and Utilization for the Elderly in Rural America

Description: The aging experience of men and women in rural America is different than that of their urban counterparts. In this study, I identified key disparities in access to health care, mortality, and utilization of health care that result from geographic location. Foundational theories are discussed to illustrate that disparities can originate from historical societal behaviors. Secondary data and literary reviews create a combined qualitative and quantitative approach to explore the rural/urban divide… more

John Ireland's Piano Sonata (1918-1920) and the Influence of Johannes Brahms

Description: John Ireland is one of the most important British composers of the twentieth century. Many scholars believe the works of his early period were deeply influenced by Brahms. After graduating from the Royal College of Music, Ireland went on to develop a much more individual musical language, with influence from contemporary French composers. However, the young composer found himself confronted with the challenge of finding a new and personal style without turning wholly to impressionism or to chro… more

Urban Elementary School Students' Conception of Learning: A Phenomenographic Mapping of Variation

Description: For decades, urban public schools have been plagued by systemic and structural challenges that continue today. Scholars, policymakers, and the general public have pointed to problems of learning in urban schools and to low expectations for urban students' learning, but little attention has been given to how urban students themselves conceptualize learning. This study sought to fill the void by asking a group of urban students about their views of learning. A phenomenographic approach was emp… more
