A Multi-Proxy Approach For Understanding The Chicxulub Asteroid Impact (Cretaceous / Paleogene Boundary) And Its Aftermath, Hermann D. BermúDez

Theses, Dissertations and Culminating Projects

The Chicxulub asteroid impact in what is now the Yucatan Peninsula, Mexican Caribbean, coincides with the Cretaceous/Paleogene boundary (K/Pg boundary ~66Ma) and marked the extinction of three-quarters of the species, including the iconic non-avian dinosaurs. The collision created a massive crater, releasing enormous amounts of energy and expelling millions of tons of molten and vaporized materials into the atmosphere. Chicxulub is an ideal case study for massive impact events since it is the only recognized asteroid impact on Earth's history that preserved a globally traceable ejecta layer representing a precise time-stratigraphic marker. Although numerous studies have examined the consequences of …

Simulation Of Photochemical Effects On Air Quality, Grace Li

Chemical Engineering Undergraduate Honors Theses

Nitrogen dioxide (NO₂) and ozone (O₃) are both EPA criteria air pollutants in the troposphere, largely generated by combustion and therefore present in significant concentrations in urban areas. Sunlight facilitates chemical reactions between pollutants and ambient air. Aerosols modulate the amount of available energy required to drive such photochemical reactions, ultimately impacting air quality. Simulating photolysis rates with FastJX software is a resource-efficient strategy to study how these aerosols can affect air quality.

Investigating The Influence Of Experimental Parameters On The Formation Of Gold Nanoparticles: A Green Synthesis And Design Of Experiments Approach, Isaac Opeyemi Subuloye

Master's Theses

This thesis examines the green synthesis of gold nanoparticles using catechin, a naturally occurring plant-derived compound, as both a reducing and capping agent. The synthesis process was guided by a structured Design of Experiments (DOE) methodology to ensure systematic investigation and optimization. A two-phase experimental approach was adopted. First, a full factorial screening design was used to evaluate the effects of catechin concentration, NaOH concentration, and pre-reaction time. This was followed by an optimization phase using a face-centered composite design to identify conditions that produce nanoparticles with ideal characteristics. The nanoparticles were analyzed using UV-visible spectroscopy and dynamic light scattering …

Identity Resolution In Feminists Raised Catholic: A Narrative Analysis Of Life Histories, Carlotta Reinhardt, Lauren E. Duncan

Psychology: Faculty Publications

Using narrative analysis of life histories, we explored the interplay between Catholic religious background, identity formation, and feminist activism. We used data from 13 oral histories of feminist and LGBTQ+ activists in the US and Italy who were raised Catholic. In the first stage of Downing and Roush’s model of feminist identity development, passive acceptance, religion can play a significant role. We found that whether religion is central to a person's worldview or not, and whether it is rigid or flexible, influence how individuals handle identity conflicts related to gender and sexuality during the revelation stage. Dissonances were caused by …

The Proust Effect And Hoarding Symptoms: Relationships Among Memory Vividness, Object Type, And Urge To Save, Lauren Milgram, Junjia Xu, Randy O. Frost, Elizabeth A. Offermann, Kiara R. Timpano

Psychology: Faculty Publications

Background: Individuals with hoarding disorder exhibit heightened attachment to objects, but little is known about possible drivers of object attachment and associated object saving behaviors. Theory and preliminary evidence posit that the heightened object attachment characteristic of hoarding disorder may be partially explained by the experience of vivid,‘Proustian’ memories related to objects.

Aims: The current study piloted a novel Proustian Memory Task to examine whether self-reported vividness of memories associated with cherished objects, mundane objects, and non-objects was associated with greater urge to save objects and greater hoarding symptoms.

Method: Participants (N= 443) included a non-selected community sample recruited from …

Optimizing Delphinium And Larkspur Through Timing And Protective Cultivation Methods For Cut Flower Production, Nicholas Kirwan Volesky

All Graduate Theses and Dissertations, Fall 2023 to Present

Cut flowers have become an increasingly important specialty crop for small farms nationwide, and particularly in Utah, where decreasing agricultural land has heightened the need for profitable cropping options. However, production is challenged by Utah’s high-elevation climate, which presents unique constraints not addressed by current recommendations. Cool-season crops, like delphinium (Delphinium spp.) and larkspur (Consolida ajacis L.), are underproduced yet highly marketable, generating strong interest among growers throughout the state. Developing region-specific production guidelines is essential to help optimize yields, extend harvest windows, and meet local demand. This research evaluated spring planting dates in high tunnel and field …

Exploring Adverse Childhood Experiences And Bullying Of Children Who Are Deaf Or Hard Of Hearing, Alyson Connelly Ward

All Graduate Theses and Dissertations, Fall 2023 to Present

Adverse childhood experiences (ACEs) and bullying can lead to psychological distress, causing both short- and long-term health and mental health problems. Children with special healthcare needs (CSHCN), including those who are deaf or hard of hearing (DHH), face a higher risk of ACEs and bullying, which can affect their well-being.

This study builds on existing literature by (a) reviewing ACEs and bullying in CSHCN, especially those who are DHH, and (b) using data from the 2016-2022 National Survey of Children's Health to analyze ACEs and bullying in children who are DHH, DHH+CSHCN, and CSHCN. The literature review found that disability …

Morphological Correlates Of Limaxivory In Contia (Serpentes: Dipsadinae) Compared To Related Taxa Carphophis And Diadophis, Lauren A. Houstoun

All Graduate Theses and Dissertations, Fall 2023 to Present

Differences in the skull and musculature of snakes can often be linked to their diet. Snakes that eat snails and slugs have evolved independently at least four times. Several skull features of the skull have already been reported in snakes that eat snails, specifically those in the genus Pareas and some Dipsadini. Among those features are a shorter, more compressed snout and, in some species, asymmetry of the lower jaw. However, little attention has been paid to snakes that specialize only on slugs (limaxivores). Unlike the snail-eating members of the Pareidae and Dipsadini, limaxivores lack the morphological traits associated with …

Setting Salinity Water-Quality Standards Protective Of Aquatic Life: Insights From Analyses Of The Effects Of Salinity On Stream Insects, Katlyn M. Gardner

All Graduate Theses and Dissertations, Fall 2023 to Present

Freshwater ecosystems are becoming saltier due to human activities like agriculture, urbanization, and resource extraction. This change in salinity is important because we know very little of how stream salinity affects aquatic insects at natural concentrations, much less at elevated concentrations. Increases in salinity may harm aquatic macroinvertebrates, which play important roles in stream food webs and are widely used as indicators of ecosystem health. Understanding how salinity affects aquatic insect growth, survival, and distribution is critical for developing effective criteria protective of aquatic life, but existing methods often rely on field surveys where multiple environmental factors covary, making it …

Still "The Last Best Place"?: Concentrated Ownership, Amenity Migration, And Community Change In Southwest Montana, Elizabeth A. Bennett

All Graduate Theses and Dissertations, Fall 2023 to Present

Across the American West, amenity rich areas have been grappling with population growth, economic shifts, and associated community impacts. Amenity migration, the movement of wealthy suburban and urban individuals to rural areas for the natural amenities and slower paced life, has contributed to much of the change in amenity rich rural places. However, recently, a new process has begun occurring simultaneously with amenity migration. New high net worth (HNW) individuals have been purchasing large parcels of land, often through the acquisition of multiple ranches that are thousands of acres. Little is known about how these new HNW owners impact the …

The Collapse Of Negara Hukum: How Indonesia’S Rule Of Law Has Been Shaped By Embedded Oligarch Politics?, Herlambang Perdana Wiratraman

The Indonesian Journal of Socio-Legal Studies

This article argues recent performance of the rule of law in the 25-years period after Soeharto’s authoritarian regime. Why has there been a weakening of civil liberties, while on the other hand the oligarchic power and authoritarianism strengthens the current Indonesia’s politics. This article examines the prevalence of arbitrary practices, not only in the fair procedural process of law enforcement, but also why it is so easy to pass anti-democratic laws that contradict the principles of the rule of law. By referring to three specific case studies: free expression, academic freedom and press freedom, this article found that politics in …

Political Violence, Electoral Behavior, And Their Interaction With Identity, Zeeshan Saeed

All Graduate Theses and Dissertations, Fall 2023 to Present

The research takes Pakistan as a case-study to explores how political violence shapes electoral behavior by focusing on two forms of violence: terrorist interventions by non-state actors and political repression by state institutions. Analyzing multiple elections and regional contexts, the study investigates how fear inflicting non-state violence can discourage voter participation, while state sponsored violence can drive communities by triggering anger, particularly those with strong ethnic identities leading to a higher voter turnout. Overall, this work highlights how different types of violence have varying effects on voter participation, and how these effects are conditioned.

Examining The Development Of Collective Classroom Efficacy At The Secondary Level, Bradley K. Dutson

All Graduate Theses and Dissertations, Fall 2023 to Present

How can educators develop cohesive and productive learning communities at the secondary level? Prior research has investigated how classrooms develop collective classroom efficacy (CCE) or the shared belief that, as a classroom, they can achieve their learning goals together as a community. Previous studies suggest that CCE at the elementary level is developed with a teacher acting in the role of a community organizer. The teacher employs social and academic practices which incorporate the use of relevance, relationship, and responsibility. These help to establish four key elements of developing CCE which include: 1) a positive classroom environment, (2) persistence and …

Pressure Recovery Analysis Downstream Of Valves And Meters: An Experimental And Numerical Investigation, Stephen J. Sanders

All Graduate Theses and Dissertations, Fall 2023 to Present

In pressurized water systems, flow control devices such as valves and meters cause pressure losses that can affect energy efficiency and measurement accuracy. Industry standards assume that all devices recover within the same distance downstream, but this may not be true for all device types. In this study we used laboratory testing and computer modeling to determine how far downstream pressure stabilizes after flowing through various valves and meters. Devices like Venturi meters recovered pressure quickly, while orifice plates required longer distances and resulted in greater permanent energy loss. In most cases, pressure recovered within four to six pipe diameters. …

A Review: The Beauty Of Serendipity Between Integrated Circuit Security And Artificial Intelligence, Chen Dong, Decheng Qiu, Bolun Li, Yang Yang, Chenxi Lyu, Dong Cheng, Hao Zhang, Zhenyi. Chen

Research Collection School Of Computing and Information Systems

Integrated circuits are the core of a cyber-physical system, where tens of billions of components are integrated into a tiny silicon chip to conduct complex functions. To maximize utilities, the design and manufacturing life cycle of integrated circuits rely on numerous untrustworthy third parties, forming a global supply chain model. At the same time, this model produces unpredictable and catastrophic issues, threatening the security of individuals and countries. As for guaranteeing the security of ultra-highly integrated chips, detecting slight abnormalities caused by malicious behavior in the current and voltage is challenging, as is achieving computability within a reasonable time and …

Solving Two-Stage Stochastic Integer Programs Via Representation Learning, Yaoxin Wu, Zhiguang Cao, Wen Song, Yingqian Zhang

Research Collection School Of Computing and Information Systems

Solving stochastic integer programs (SIPs) is extremely intractable due to the high computational complexity. To solve two-stage SIPs efficiently, we propose a conditional variational autoencoder (CVAE) for scenario representation learning. A graph convolutional network (GCN) based VAE embeds scenarios into a low-dimensional latent space, conditioned on the deterministic context of each instance. With the latent representations of stochastic scenarios, we perform two auxiliary tasks: objective prediction and scenario contrast, which predict scenario objective values and the similarities between them, respectively. These tasks further integrate objective information into the representations through gradient backpropagation. Experiments show that the learned scenario representations can …

Bhvit: Binarized Hybrid Vision Transformer, Tian Gao, Yu Zhang, Zhiyuan Zhang, Huajun Liu, Kaijie Yin, Chengzhong Xu, Hui Kong

Research Collection School Of Computing and Information Systems

Model binarization has made significant progress in enabling real-time and energy-efficient computation for con-volutional neural networks (CNN), offering a potential solution to the deployment challenges faced by Vision Transformers (ViTs) on edge devices. However, due to the structural differences between CNN and Transformer architectures, simply applying binary CNN strategies to the ViT models will lead to a significant performance drop. To tackle this challenge, we propose BHViT, a binarization-friendly hybrid ViT architecture and its full binarization model with the guidance of three important observations. Initially, BHViT utilizes the local information interaction and hierarchical feature aggregation technique from coarse to fine …

Artificial Intelligence On Campus: Revisiting Understanding As An Aim Of Higher Education, Jamie Herman, Henry Lara‐Steidel

Prindle Faculty and Staff Publications

AbstractThe launch of the powerful generative AI tool ChatGPT in November 2022 sparked a wave of fear across higher education. The tool could seemingly be used to write essays and do other work without students putting in the effort expected of them. In this paper, Jamie Herman and Henry Lara‐Steidel posit a way of addressing the concerns over ChatGPT and increasingly powerful generative AI tools in the classroom by first examining what exactly, if anything, widespread AI use undermines in education. That question, they argue, is logically prior to the question of what to do or how best to embrace …

A Study Of The History, Repertory And Instrumentation Of The Band Of The Corfu Philharmonic Society From 1840 Until 1920, Foteini Angeli

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

The Corfu Philharmonic Society band was founded in 1840 and is still active today. It is considered the one of the oldest continuously operating music education organizations in Greece. The people, repertoire, and instrumentation of this band influenced all other wind bands in Greece. There are important resources available on the topic, but dedicated research to the organization is in its infancy. Focusing on the changes in instrumentation through original manuscripts from the inaugural band (1840) through the end of the First World War reveals significant multinational influences that continue to be felt to this day. This is the first …

Traffic Prediction For Research And Education Networks: Anomaly-Aware Deep Learning And Benchmarking, Mohammad Arafath Uddin Shariff

School of Computing: Dissertations, Theses, and Student Research

Research and Education Networks (RENs) and High-Performance Computing (HPC) environments are critical infrastructures for modern scientific discovery, demanding sustained high-throughput and low-latency data transfers. Unlike commercial networks, RENs exhibit unique traffic characteristics, including predominant “elephant flows,” inherent burstiness, and complex temporal-spatial dynamics often decoupled from human-driven cycles. Traditional traffic forecasting methods, tailored for commercial Wide Area Networks (WANs), consistently fail to capture these distinct REN dynamics, leading to inefficient resource management and potential impediments to scientific progress.

This thesis addresses this critical gap by developing and validating a robust, scalable, and anomaly-aware traffic forecasting framework specifically tailored for REN/HPC networks. …
