Procedural Pre-Training For Visual Recognition, Connor S. Anderson

Theses and Dissertations

Deep learning models can perform many tasks very capably, provided they are trained correctly. Usually, this requires a large amount of data. Pre-training refers to a process of creating a strong initial model by first training it on a large-scale dataset. Such a model can then be adapted to many different tasks, while only requiring a comparatively small amount of task-specific training data. Pre-training is the standard approach in most computer vision scenarios, but it's not without drawbacks. Aside from the cost and effort involved in collecting large pre-training datasets, such data may also contain unwanted biases, violations of privacy, …

A Grounded Theory Analysis Of Honesty And Deception In Intimate Relationships, Lyndsey Kunzler Gerring

Chemical Herding As A Multiplicative Factor For Top-Down Manipulation Of Colloids, Mark N. Mcdonald, Douglas R. Tree, Cameron K. Peterson

Faculty Publications

Colloidal particles can create reconfigurable nanomaterials, with applications such as color-changing, self-repairing, and self-regulating materials and reconfigurable drug delivery systems. However, top-down methods for manipulating colloids are limited in the scale they can control. We consider here a new method for using chemical reactions to multiply the effects of existing top-down colloidal manipulation methods to arrange large numbers of colloids with single-particle precision, which we refer to as chemical herding. Using simulation-based methods, we show that if a set of chemically active colloids (herders) can be steered using external forces (i.e., electrophoretic, dielectrophoretic, magnetic, or optical forces), then a larger …

Manipulating Colloidal Particles Using Chemical Gradients And Top-Down Control, Mark Nichols Mcdonald

Theses and Dissertations

Colloidal particles provide the ideal building blocks for the next generation of microdevices, such as advanced sensors and precision drug delivery systems. However, many such applications require the use of top-down (i.e. humanly controllable) forces to manipulate colloidal particles with single-particle precision, and current methods can only achieve such precision for small numbers of particles at a time. To address this challenge, we propose using chemical forces in combination with existing top-down techniques to enable the control of larger numbers of particles simultaneously. Controlling colloids using chemical reactions is a novel technique not typically utilized. Due to its distinct difference …

Leveraging Biological Mechanisms In Machine Learning, Kyle J. Rogers

Theses and Dissertations

This thesis integrates biologically-inspired mechanisms into machine learning to develop novel tuning algorithms, gradient abstractions for depth-wise parallelism, and an original bias neuron design. We introduce neuromodulatory tuning, which uses neurotransmitter-inspired bias adjustments to enhance transfer learning in spiking and non-spiking neural networks, significantly reducing parameter usage while maintaining performance. Additionally, we propose a novel approach that decouples the backward pass of backpropagation using layer abstractions, inspired by feedback loops in biological systems, enabling depth-wise training parallelization. We further extend neuromodulatory tuning by designing spiking bias neurons that mimic dopamine neuron mechanisms, leading to the development of volumetric tuning. This …

Feasibility Of Parallelized Measurement Of Local Thermal Properties, Alexander J. Hansen

Theses and Dissertations

This thesis documents research done in the development and the exploration of feasibility for a high-throughput method to measure local thermal properties. The present capabilities in the measurement of local thermophysical properties such as thermal conductivity, thermal diffusivity, and Kapitza resistance are very inefficient and impractical to fully understand and characterize heat transport through certain materials and features. This work follows up on past work in local thermal property measurement via the spatial domain thermoreflectance (SDTR) method, and explores the possibility of parallelizing the process. The parallelized SDTR (P-SDTR) method involves using laser projector sources to periodically heat and measure …

Factors Surrounding Mental Health Well-Being For Male Adolescent Pacific Islanders, Melia Fonoimoana Garrett

Theses and Dissertations

Despite increasing mental health concerns, individuals from the Pacific Islands largely do not utilize the resources available to them (National Survey of Drug Use and Health, 2020). This is of particular concern among male adolescents within the population who are more at risk of mental health concerns. An interpretative phenomenological analysis focus group study was conducted in person with male adolescent Pacific Islanders (PI; ages 14–16) residing in one Western state (n = 3). Male adolescents reported that admitting to mental health concerns would greatly limit their academic, career, and personal ambitions due to the stigma attached. They also discussed …

Challenging The Master Narrative Of Holocaust Victimhood: Examining The Holocaust Through A Gendered Lens, Annabella Blowers

Undergraduate Honors Theses

Women are severely unrepresented in the master narrative that has come to define what it means to be a Holocaust victim. Although men and women were subjected to different forms of victimization, women’s unique experiences of suffering have been marginalized and subsumed within the male-dominated master narrative. Examining the Holocaust through a gendered lens challenges this existing narrative of Holocaust victimhood. Conducting a gender analysis of the Holocaust is essential to fully incorporate women’s experiences into Holocaust history and the grossly inadequate narrative society uses to define Holocaust victimhood.

An analysis of fifty Holocaust fiction novels revealed that literature’s depiction …

What The Eye Doesn't See: The Power Of Non-Ocularcentric Engagement In Museum Learning, Sophie J. Houghton

Undergraduate Honors Theses

Museums are unique spaces of teaching and learning. Museum exhibits transcend the constraints of classroom learning by leveraging visitors’ curiosity and allowing for increased learning autonomy. However, this learning often comes solely through visual interaction, due to museums’ role in preservation and protection of their collection. Though visual-based learning is common in museums and in Western education at large, multisensory elements cement learning autonomy and prompt visitors to learn through play. These principles are exemplified through children’s’ museums, science museums, and museum adaptations for blind and low-vision visitors. Through multisensory adaptations, traditional museums can transform their impact on visitors. This …

Teaching Resilience In Pacific Islander Children Through Culturally Adapted Stories, Isabel Medina Hull

Theses and Dissertations

This study investigated the efficacy of culturally adapted bibliotherapy in promoting resilience among American Samoan children aged 5-13 years in response to high adolescent suicide rates in the Pacific Islands and the need for culturally adapted and supportive interventions grounded in mental health wellness. Bibliotherapy, particularly the identification with story characters, has been recognized for bolstering mental wellness, resilience, and emotional regulation in children. In this research, the children's response to bibliotherapy was measured through card sorting and forced-choice exercises, assessing their engagement with literature mirroring their experiences. The materials were developed in collaboration with Samoan cultural brokers on island …

One Size Does Not Fit All: Creating Educational Equity For Later Diagnosed Autistic Women, Naomi Julian

Undergraduate Honors Theses

Autism research focuses on the externalized behaviors usually associated with the male phenotype of autism with little representation of the internalized behaviors associated with the female phenotype of autism. Even more so, there is little research involving later diagnosed autistic women — especially women of color. Beyond this, non-white individuals have been marginalized within the sphere of education, and their marginalization is exacerbated by an autism diagnosis.

In the realm of schooling, the relationship between race, gender, and disability lacks investigation. In this exploratory study, I draw upon qualitative data from interviews of 17 racially diverse autistic women ages ranging …
