The Inverse Elasto-Acoustic Problem, Patrick Grice

Dissertations

A stable and numerically efficient boundary integral method formulation of the elasto-acoustic problem is presented, based on Fourier analysis. The method generalizes well to multiple scattering. The Frechet derivative of the elasto-acoustic problem with respect to shape perturbations is derived, and geometric flow theory is used to design stable numerical methods for the simulation of moving boundaries. The shape derivative is used to define a regularized Gauss-Newton algorithm for shape fitting of elasto-acoustic scatterers.

The Experience Of Bipoc Participants In Wilderness Therapy, Rachel Esrig

Doctoral Dissertations

Wilderness therapy is an alternative to residential treatment for adolescents and young adults. Although these programs predominantly serve White-identifying individuals, a proportion of participants identify as Black, Indigenous, and/or People of Color (BIPOC). Research has shown that race and ethnicity shape individuals’ experiences with mental health treatment; however, no studies to date have specifically explored the experiences of BIPOC individuals in wilderness therapy programs. This qualitative study addresses that gap by examining the experiences of BIPOC individuals who participated in wilderness therapy during adolescence. Using an interpretive phenomenological approach, nine themes emerged from the data. Findings suggest that participants’ levels …

Unveiling Racism: A Systematic Review Of Racism Survey Measures In Education, Wendy Castillo, Juan Cruz, Rachel Renbarger, Christen Priddie, Brein Mosely, Sasha Mejia-Bradford

Department of Psychology Faculty Scholarship and Creative Works

Education policy research aimed at eliminating racism necessitates methodological innovation that fosters both racial equity–centered approaches and robust empirical analysis of the systemic and structural nature of racism. Most quantitative research in educational psychology does not account for racism in its modeling, thereby obscuring the racialized environments in which students learn (DeCuir-Gunby & Schutz, 2014; Strunk & Andrzejewski, 2023). Drawing from Bronfenbrenner’s ecological systems theory and the ethos of QuantCrit, this study evaluates various scales to highlight gaps and challenges in measuring racism within school settings. This review aims to uplift measures for researchers to use in their work and …
