Emerging Technologies And Advanced Analyses For Non-Invasive Near-Surface Site Characterization, Aser Abbas

All Graduate Theses and Dissertations, Fall 2023 to Present

This dissertation introduces novel techniques for estimating the soil small-strain shear modulus (G_max) and damping ratio (D), crucial for modeling soil behavior in various geotechnical engineering problems. For G_max estimation, a machine learning approach is proposed, capable of generating two-dimensional (2D) images of the subsurface shear wave velocity, which is directly related to G_max. The dissertation also presents a method for estimating frequency dependent attenuation coefficients from ambient vibrations collected using 2D arrays of seismic sensors deployed across the ground surface. These attenuation coefficients can then be used in an inversion process …

The Rise And Fall Of Elizabeth Holmes: Investigating Myths Within Media Coverage, Charlotte Emelia Williams

All Graduate Theses and Dissertations, Fall 2023 to Present

When Elizabeth Holmes became the youngest female billionaire in 2014, news media framed her as the next Steve Jobs due to her similarities as a dropout, a passionate industry disruptor, and a visionary. When she was discovered as a fraud in 2018, coverage framed her as a feminine, seductive monster who duped everyone. I analyzed the media coverage in both years to uncover myths that guided these narratives and argue that these news frames contributed to the large interest in her rise and fall while also reinforcing harmful ways of thinking toward success and female leadership.

An Examination Of The Effects Of Prey Density, Mortality, Nutrients, And Foraging Tradeoffs On A System With Inducible Defenses: An Empirical And Theoretical Approach, Benjamin C. Ralston Daniel

All Graduate Theses and Dissertations, Fall 2023 to Present

To grasp the functioning and stability of ecosystems, it is important to understand species interactions. With many ecosystems becoming more imperiled from urbanization and anthropogenic influences it is important to understand ways in which species can adapt to rapid changes in their environment. Phenotypic plasticity is one such tool at nature’s disposal to initiate rapid change, where species with the same genetic makeup can have different expressed traits depending on their environment. Inducible defenses are one such form of phenotypic plasticity in which prey can express different levels and forms of defense depending on the threat of predation present in …
