Fight At The Museum: An Ethnographic Study Investigating Staff And Volunteers At Wwii Museums And Memorials, Miranda Noland

Master's Theses

Museums are places where events of the past can be explained, appreciated, and understood. While efforts are often taken to provide a neutral position in the presentation of complicated and emotional historical events, there may exist external pressure to present a more overtly nationalist narrative to please a particular audience or group of funders (Fujitani 1997). This creates a conflict of interest with respect to fair, accurate, and/or honest representation (White 1997b) for museum staff to navigate.

The goal of this thesis is to investigate stories that museums are permitted to tell within the context of Japanese and American narratives …

Lack Of Inflammatory Response In Mouse Embryonic Cells To Listeria Infection, Damilola Oyebode

Master's Theses

Approximately 1 in 5 pregnancies in the United States results in miscarriage, with a significant percentage of these losses attributed to failed implantation due to immunological challenges encountered by the early embryo. Recent research has shown that key cell types within mouse blastocysts, including embryonic stem cells (ESCs) and trophoblast stem cells (TSCs), exhibit remarkable resilience against the cytotoxic effects associated with viral infections and embryotoxic cytokines, such as TNFα and IFNγ, both of which are known to hinder blastocyst development. However, the immune properties of the preimplantation stage embryo, specifically the blastocyst, remain poorly understood. Using mouse cell model, …

Soldiers In The Sideshows: The 409th Infantry Regiment In World War Ii, Nicholas Garrett

Master's Theses

In the European Theater of World War II certain battlefields or campaigns such as Operation Overlord, Operation Market Garden, and the Battle of the Bulge are core aspects of American memory.

Just Deserts: The Moral Foundations Of Antagonistic Personality In Social Aggression, Summer Steely

Master's Theses

Social aggression is associated with adverse psychosocial consequences such as anxiety, depression, isolation, reciprocal violence, and suicidality (Zhu et al., 2024). Psychopathic personality traits and moral deficits have been linked to antisocial behavior, including social aggression; however, the role of moral value systems and trait moral disengagement in the context of social aggression is less clear. A more granular analysis of their utility may illuminate new pathways toward intervention. To advance this goal, the present study explored the relationships between the values of Moral Foundations Theory and social aggression among college students (N = 301). Two moral foundations (i.e., care …

Corrugated core composites were produced with traditional manufacturing methods, namely compression molding, using twelve stacking sequences. These stacking sequences were chosen to represent four laminate groups, where a unique fiber orientation scheme was employed across three laminate thicknesses (6, 8, and 12 layers). In contrast, honeycomb and …

Finite Element Analysis And Verification Of Transverse Mechanical Properties Of Generally Cylindrical Orthotropic Constitutive Modeling Of 3-Phase Nanocomposite Unit Cell, Christopher J. Hawkins

Master's Theses

Fiber-reinforced composites are increasingly popular due to their specific strength and stiffness, making them ideal for high-performance applications. However, these materials primarily exhibit superior properties in-plane, while their out-of-plane characteristics remain comparatively weaker. Previous research has shown that the most effective method to enhance out-of-plane properties involves the incorporation of carbon nanotubes. Experimental tests have demonstrated significant improvements in properties such as tension, flexural, short beam shear, and fracture toughness. Alongside these experimental studies, analytical equations have been developed to predict the behavior of these composites under various loading conditions, including tension, bending, shear, and fracture. Existing models primarily address …

Policies And Price Controls On The Research And Development Of Orphan Drugs In The United States And The European Union, Bena Pearl Filipczak Smith

Master's Theses

There is substantive literature surrounding the impact of price controls on the research and development (R&D) of new pharmaceutical products. The European Union (EU) and United States (US) are often studied in contrast to examine the influence of price controls as the US has fewer pharmaceutical price controls than the EU.

We find moderate evidence that the US spent more on annual domestic pharmaceutical R&D than the EU between 2004 and 2021, on average, before and after adjusting for GDP growth per capita and year. We find strong evidence that the US increased annual domestic R&D spending at a faster …

Modeling Hourly Storm Surges Using Deep Learning Techniques, Md Abu Zafor

Master's Theses

Storm surges cause coastal flooding, one of the most devastating coastal hazards. Accurate modeling of storm surges is essential for predicting and mitigating these impacts. Traditional approaches model surges at individual tide gauges and often focus on daily time scales, leading to data redundancy and limiting their ability to capture sub-daily variability. This study addresses these limitations using deep learning (DL) algorithms to model hourly surges simultaneously at multiple tide gauges along the U.S. East Coast and Gulf of Mexico. Three algorithms, Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM), and a hybrid ConvLSTM are employed to model surges using …

Construction, Emplacement, And Structure Of Cretaceous Plutons In The Ebbetts Pass Region, North-Central Sierra Nevada Batholith, California, Hollianne C. Mcclure

Master's Theses

Field, petrographic, and geochronologic analyses were conducted for five Cretaceous plutons in the North-Central Sierra Nevada batholith to better understand their construction, emplacement, and deformation histories. All the plutons in the study area were constructed incrementally, but timing and degrees of mixing between increments vary. The lack of internal contacts and heterogeneity in the interiors of the Stanislaus Meadow and Ebbetts Pass plutons suggest that there were sizeable magma chambers where there was thorough mixing of increments. The West of Elbow, Lookout Peak, and Kinney Lakes plutons were constructed from small batches of magma based on their textural and compositional …
