Politics Of Problem Definition: Comparing Public Support Of Climate Change Mitigation Policies Using Machine Learning, Junghwa Choi, Wesley Wehde, Romit Maulik

Public Administration Faculty Publications

Public support is a key contributor to successful policy adoption and implementation. Given the urgency of climate change mitigation, scholars have explored various determinants that affect public support for climate change mitigation policy. However, the relative decisiveness of these factors in shaping public support is insufficiently examined. Therefore, we deploy interpretable machine learning to understand which factors, among many previously investigated, are most decisive for structuring public support for various climate change mitigation policies. In this paper, we particularly look at the decisiveness of problem definition for shaping public support among various factors. Using U.S national survey data, we find …

The Design, Synthesis, And Investigation Into Small Molecule Modulators Of The Src Homology 2 Domain-Containing Inositol 5’-Phosphatase (Ship), Shea Thomas Meyer

Dissertations - ALL

The PI3K pathway is a major cell signaling pathway that influences survival and longevity in eukaryotic cells. Abnormal signaling of this pathway has been implicated in a number of disorders, including Alzheimer's disease and cancer. The PI3K pathway utilizes the inositolphospholipid PI(3,4,5)P3 as a key secondary messenger in the transmission of signals from outside the cell to the nucleus. The SRC Homology 2 containing Inositol 5’-Phosphatase (SHIP) also plays a key role in the PI3K pathway, mediating hydrolysis of the inositol phospholipid PI(3,4,5)P3 to PI(3,4)P2. Early testing has shown modulation of SHIP activity through the use of small molecule modulators …

Determinism Beyond Time Evolution, Emily Adlam

Mathematics, Physics, and Computer Science Faculty Articles and Research

Physicists are increasingly beginning to take seriously the possibility of laws outside the traditional time-evolution paradigm; yet many popular definitions of determinism are still predicated on a time-evolution picture, making them manifestly unsuited to the diverse range of research programmes in modern physics. In this article, we use a constraint-based framework to set out a generalization of determinism which does not presuppose temporal evolution, distinguishing between strong, weak and delocalised holistic determinism. We discuss some interesting consequences of these generalized notions of determinism, and we show that this approach sheds new light on the long-standing debate surrounding the nature of …

Multifrequency Scintillation In The Polar Caps, Tate Colby

Doctoral Dissertations and Master's Theses

In the ionosphere, plasma density structures with scales sizes ranging from a few centimeters to hundreds of kilometers are capable of modifying the phase and amplitude of a radio signal in a rapid random manner in a process called scintillation. The Coherent Electromagnetic Radio Tomography (CERTO) and the Canadian High Arctic Ionospheric Network (CHAIN) are two different networks of scintillation receivers, each with a station in Resolute Bay, Canada. CERTO measures amplitude and phase signals in VHF and UHF while CHAIN measures amplitude and phase signals in the L-band. Through these measurements we can calculate the scintillation indexes, S_4 and …

Development And Deployment Of A Dynamic Soaring Capable Uav Using Reinforcement Learning, Jacob Adamski

Doctoral Dissertations and Master's Theses

Dynamic soaring (DS) is a bio-inspired flight maneuver in which energy can be gained by flying through regions of vertical wind gradient such as the wind shear layer. With reinforcement learning (RL), a fixed wing unmanned aerial vehicle (UAV) can be trained to perform DS maneuvers optimally for a variety of wind shear conditions. To accomplish this task, a 6-degreesof- freedom (6DoF) flight simulation environment in MATLAB and Simulink has been developed which is based upon an off-the-shelf unmanned aerobatic glider. A combination of high-fidelity Reynolds-Averaged Navier-Stokes (RANS) computational fluid dynamics (CFD) in ANSYS Fluent and low-fidelity vortex lattice (VLM) …

Improving Spatial Resolution Of Time Reversal Focusing Using Arrays Of Acoustic Resonators, Adam David Kingsley

Theses and Dissertations

Using a near-field array of acoustic resonators, it is possible to modify a focused pressure field and enforce a spatial frequency corresponding to the resonator array spacing. This higher spatial frequency makes it possible to focus and image with a resolution that is better than if the focusing were in free space. This near-field effect is caused by the phase shifting properties of resonators and, specifically, the delayed phase found in waves with a temporal frequency lower than that of the resonators in the array. Using time reversal, arrays of resonators are explored and the subwavelength focusing is used to …

The testing of the model was found to be simple and intuitive, and the research concludes that the model is applicable to enterprise SSBI environments. This research is …

Estimation Of Cotton Canopy Parameters Based On Unmanned Aerial Vehicle (Uav) Oblique Photography, Jinyong Wu, Sheng Wen, Yubin Lan, Xuanchun Yin, Jiantao Zhang, Yufeng Ge

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background: The technology of cotton defoliation is essential for mechanical cotton harvesting. Agricultural unmanned aerial vehicle (UAV) spraying has the advantages of low cost, high efficiency and no mechanical damage to cotton and has been favored and widely used by cotton planters in China. However, there are also some problems of low cotton defoliation rates and high impurity rates caused by unclear spraying amounts of cotton defoliants. The chemical rate recommendation and application should be based upon crop canopy volume rather than on land area. Plant height and leaf area index (LAI) is directly connected to plant canopy structure. …

Focusing Of High-Amplitude Sound Waves Using The Time Reversal Process, Brian D. Patchett

Theses and Dissertations

Time reversal is a method often used to focus sound to a desired location, and works best in a reverberant environment. The effect of focus location within a reverberant environment is presented first, revealing that proximity to reflecting surfaces has a significant effect on the amplitude of the focus both experimentally and when using a modal summation model. These effects are a primary component to creating focus signals at high amplitudes. High-amplitude focusing experiments show that when multiple sources are used simultaneously to generate a focus, a peak amplitude pressure spike of 200 dB can be achieved in air. A …

Evidence-Based Study: The Effect Of The Covid-19 Pandemic On Post-Secondary Enrollment And Chosen Fields Of Study, Hannah Fields '25

Student Research

The onset of the COVID-19 pandemic in the United States in March of 2020 derailed educational systems at all levels. Specifically, at the post-secondary level, the pandemic sent many students online or forced them to take a fifth year to complete their degrees. As a result, post-secondary enrollment rates are likely to have dropped to reflect these changing post-COVID views surrounding education. Additionally, changing viewpoints about the essentiality of certain jobs and roles changed the chosen fields of study of these same students. Data for this study was collected by way of a short-scale meta-analysis, and enrollment rates were split …

This paper proposes a predictive approach based on our proposed algorithm Enhanced Adaptive Guided Differential Evolution (EAGDE) is used to optimize the parameter selection of Support Vector Machine (SVM) to give high RUL prediction accuracy. The advantages of the proposed approach (EAGDE–SVM) are verified using the popular benchmark C-MAPSS which describes the degradation of the aircraft turbofan engine …

The First Jesuits And The First Jesuit Universities, Paul Grendler

Jesuit Higher Education: A Journal

John W. O’Malley S. J. in The First Jesuits described well the basic principles of the Jesuit educational ministry that shapeed Jesuit schools and universities. He did not discuss what constituted a Jesuit university because that was not the purpose of the book. After assessing the major contributions that O’Malley made to define the principles of Jesuit education, this article will pick up where O’Malley left off by describing the first Jesuit universities. There was not a single model of a Jesuit university. Instead, the Jesuits taught in four kinds of universities: the all-Jesuit university, the civic-Jesuit collegiate university, the …

Journal of Science Education for Students with Disabilities

We conducted a qualitative review of the research literature on STEM (science, technology, engineering, mathematics) related to high school students with disabilities (SWD). We selected and analyzed 53 articles to answer two questions: (1) How are high-school SWD prepared for careers in STEM? (2) How are educators prepared to support high-school SWD for opportunities in STEM? In answering the first question, four qualitative themes emerged: (a) barriers to STEM, (b) increasing STEM opportunities, (c) STEM readiness in college and career, and (d) STEM identity. In answering the second question, three qualitative themes emerged: (a) individualizing learning and supports for SWD, …

It builds on three sets of sources concerning teaching, researching, and practicing international law …

Hate-Clipper: Multimodal Hateful Meme Classification Based On Cross-Modal Interaction Of Clip Features, Gokul Karthik Kumar, Karthik Nandakumar

Computer Vision Faculty Publications

Hateful memes are a growing menace on social media. While the image and its corresponding text in a meme are related, they do not necessarily convey the same meaning when viewed individually. Hence, detecting hateful memes requires careful consideration of both visual and textual information. Multimodal pretraining can be beneficial for this task because it effectively captures the relationship between the image and the text by representing them in a similar feature space. Furthermore, it is essential to model the interactions between the image and text features through intermediate fusion. Most existing methods either employ multimodal pre-training or intermediate fusion, …

This project looked into four different options: air source heat pumps, ground source heat pumps, renewable natural gas, and the efficiency of current equipment. Each option was examined throughout the course of the semester to determine feasibility of each solution, and which ones would be best to implement. As a class, section A decided ground source heat pumps along with thermostatic valves and the implementation of double pane windows …

Free Radical-Based Sequencing For Native Top-Down Mass Spectrometry, Carolina Rojas Ramírez, Rayan Murtada, Jinshan Gao, Brandon T. Ruotolo

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Native top-down proteomics allows for both proteoform identification and high-order structure characterization for cellular protein complexes. Unfortunately, tandem MS-based fragmentation efficiencies for such targets are low due to an increase in analyte ion mass and the low ion charge states that characterize native MS data. Multiple fragmentation methods can be integrated in order to increase protein complex sequence coverage, but this typically requires use of specialized hardware and software. Free-radical-initiated peptide sequencing (FRIPS) enables access to charge-remote and electron-based fragmentation channels within the context of conventional CID experiments. Here, we optimize FRIPS labeling for native top-down sequencing experiments. Our labeling …

Examining Cultural And Chemical Treatments To Fusarium Bulb Rot In Onions, Tim Miller

Fall Student Research Symposium 2022

Onions are grown in 1,500 acres in northern Utah and are a large part of growers' income. In the fall of 2021, 30% of a grower's onion yield was affected by Fusarium bulb rot (caused by a fungus known as Fusarium proliferatum) and the onions were unmarketable. The literature surrounding this pathogen is sparse and losses of this magnitude could cause growers to lose between six and seven thousand dollars per acre. Samples of the fungus were plated onto potato dextrose agar at half strength and maintained fresh throughout the winter. In vitro experiments were performed with various fungicides at …

Practice Habits Among Collegiate Music Majors: Relationships With Everyday Self-Regulatory Behaviors, Lydia Stricker

Honors Projects

This study examined self-regulatory behaviors among collegiate musicians. In the fall of 2022, a total of 73 participants from a large midwestern university responded to an online questionnaire soliciting information regarding self-regulatory behaviors both in and outside of the classroom. Items were adapted from the Carey, Neal and Collins Short Self-Regulation Questionnaire (2004). Findings support previous research suggesting a strong, positive relationship between everyday self-regulatory behaviors and those demonstrated in the practice room. Implications include a discussion on the possibility of transferring self-regulation strategies from one domain to the other.

Computer Simulation Of The Light Absorption Band Of The Jumping Spider Isorhodopsin, Noah Zoldak

Honors Projects

In order to simulate the photoisomerization of the 9-cis Jumping Spider Isorhodopsin (JSiR-1) it is necessary to first simulate its light-absorption band. Here we report on the absorption band simulated using protein models constructed using the advanced Automatic Rhodopsin Modeling (a-ARM) program. A population of S₀ models was created and the corresponding S₀ to S₁ transitions were determined for each member of the resulting population. The calculation resulted in a Gaussian plot showing that the wavelength of the absorption maximum of 560 nm (a violet color) that is consistent, but red-shifted, with respect the experimentally observed value.
