Although effective governance is vital for school success, there remains a lack of clarity about how board chairs interpret their roles, fulfill their responsibilities, and navigate the unique demands of faith-based school leadership. This gap in understanding restricts the system’s ability to provide appropriate training, support, and clear …

The Symphony Of Justice: An Intertextual Study Of Social Justice Material Between The Torah And The Psalms, Daniel Gordan

Dissertations

Do passages dealing with social justice in the Torah and the Psalms together comprise an intentionally composed grand symphony, or do they merely form an ad hoc patchwork quilt in which their echoes of similarity are mere coincidences?1 Literary interactions between the Torah and the Prophets of the Hebrew Bible have been a focus of biblical scholarship, but the intertextual connections between the legal corpus of the Torah and poetry in Psalms have not received sufficient attention. Scholars have noticed some thematic similarities, but there are no systematic studies that analyze these interactions to determine whether they involve reuse and, …

A Case Study Of California Postsecondary Faculty Collaboration On Rubric Development To Foster Student Learning, Emmanuel Kwadwo Frimpong

Computational Design Of Nanoporous Materials For The Adsorption Of Per- And Polyfluoroalkyl Substances, Daniel D. Mottern

Dissertations

Per- and polyfluoroalkyl substances (PFAS) are a large family of chemicals that have seen wide usage due to their fluorinated carbon backbone. The presence of strong C-F bonds in the backbone lends PFAS molecules high thermal and chemical stability, as well as strong hydrophobicity and lipophobicity. This combination of properties has led to heavy use of PFAS as surfactants, non-stick coatings, and aqueous foam forming films and flame retardants. However, these properties bring their own consequences. The high chemical and thermal stability of PFAS renders them persistent, with the C-F bonds resisting naturally occurring forms of degradation. Existing forms of …

Entropic Forces Near Fluctuating Surfaces, Rubayet Hassan

Dissertations

Nanoscale structures are inherently dynamic due to persistent thermal fluctuations. Even in solid materials, these random deformations, driven by ambient thermal energy, can become significant when their characteristic scale approaches that of the structure itself and strongly influence their overall mechanical behavior. Examples of such structures include crystalline membranes, appearing in diverse forms such as nanotubes, nanoribbons, and kirigami/origami structures. Similarly, biological nanostructures, including lipid membranes, microtubules, actin filaments, and DNA, exhibit extreme flexibility and responsiveness due to their low bending rigidity. Numerous physiological processes are intrinsically linked to these thermal fluctuations, including exocytosis and endocytosis, membrane fusion, pore formation, …

Using Light To Dissect Mechanisms Of Septin Recruitment, Shreya Chandrasekar

Dissertations

Cells interpret biochemical and mechanical signals through dynamic regulation of the cytoskeleton and adhesion complexes, enabling key processes such as shape adaptation, force generation and migration. As these signals vary in both time and space, they can be challenging to resolve using traditional bulk assays. To overcome this limitation, we employ light-based optogenetic tools to reversibly modulate biochemical signals and mechanical equilibrium within cells. Specifically, we use the iLID optogenetic approach to locally activate signaling and manipulate contractility within the cytoskeleton for the purpose of investigating the role of RhoA and contractility on septin organization and adhesion protein localization.
