The Burden Mothers Bear: Using The Health Belief Model To Understand How U.S. Mothers’ Intersectional Identities Shape Health Decision-Making During Covid-19, Sydney O'Shay, Kaitlin E. Phillips, Marissa J. Sáez

Publications

The disproportionate impact of COVID-19 on people of color and the burden placed on mothers created a need to better understand how mothers of color made health decisions for their families and communicated these decisions with others during the pandemic. This study investigated how this populations’ intersectional identities played a role in their health decision-making processes and overall experiences during COVID-19. Using the health belief model as a sensitizing concept, we conducted qualitative in-depth interviews with mothers of color across the United States about their lived experiences during the pandemic. Our findings suggest a need for health communicators to address …

Influence Of Internalizing And Externalizing Traits On Cognitive Performance In Typically Developing Children, Carlie Sivils

Modelling V-Band Atmospheric Loss With Deep Learning, Ralph Lyndon Gesner

Electrical and Computer Engineering ETDs

Modelling atmospheric loss is fundamental to implementation of future mm-wave terrestrial and earth space communication links. Atmospheric losses have traditionally been estimated by calculating the contributions of individual weather phenomena through in-situ meteorological measurements and statistically derived models for estimating localized atmospheric water content. Collecting data for all points along the propagation path and calculating the physical effects of gases, clouds, and precipitation individually is both time consuming and impractical for large-scale use cases.

In response to these present limitations, this work proposes the use of novel deep learning models for estimating atmospheric losses from tabular meteorological sensor data and …

Coastal Marine Heatwaves In The Santa Barbara Channel: Decadal Trends And Ecological Implications, Kit Yu Karen Chan, L. Kui, A. M. Mcdonald, A. L. Ritger, G. E. Hofmann

Biology Faculty Works

Marine heatwaves (MHWs) are of increasing concern due to the emerging ecological and socioeconomic impacts on coastal ecosystems. Leveraging the data of the Santa Barbara Coastal Long-Term Ecological Research project, we analyzed the MHW event metrics observed in the kelp forest ecosystem and across Santa Barbara Channel, CA, USA. Not only was there a significant positive trend in the number of MHWs recorded, their duration and intensity were also increasing over time. MHWs were detected year-round, suggesting that marine organisms have exposure risks regardless of their phenology. Exposure at one life history stage could have a legacy effect on the …

Greening Of A Boreal Rich Fen Driven By Co2 Fertilisation, Sandeep Thayamkottu, T. Luke Smallman, Jaan Pärn, Ülo Mander, Eugénie S. Euskirchen, Evan Kane

Michigan Tech Publications

Boreal peatlands store vast amounts of soil organic carbon (C) owing to the imbalance between productivity and decay rates. In the recent decades, this carbon stock has been exposed to a warming climate. During the past decade alone, the Arctic has warmed by ∼ 0.75°C which is almost twice the rate of the global average. Although, a wide range of studies have assessed peatlands’ C cycling, our understanding of the factors governing source / sink dynamics of peatland C stock under a warming climate remains a critical uncertainty at site, regional, and global scales. Here our focus was on answering …

Operations On Submodules With The Multiplicative And Quotient Properties, Jiekai Pang

Mathematics & Statistics ETDs

Inspired by the works of Petro, Epstein, Vassilev, and Morre, this thesis aims to study the generalized definitions of the semiprime operation, weakly prime operation, and standard closure operation on rings, that is, the multiplicative operation, weakly multiplicative operation, and standardly multiplicative operation on submodules. Then, we will use Matlis duality to induce the dual notions of these definitions on submodules of Matlis-dualizable Artinian modules. In order to understand the dual notion of the standardly multiplicative operation, that is, the standardly quotient operation, we will classify the operations on the injective hull of residue field of the ring K[[x,y]]/(xy) which …

Forest Response To Increasingly Frequent Fire And Drought Disturbances, Kevin G. Willson

Biology ETDs

Changes in fire regimes and drought intensity have increased fire and drought severity in southwestern forests, decreasing forest resilience to recent changes in climate. As tree response and regeneration after disturbance are critical for forest persistence, this dissertation assesses ponderosa pine regeneration patterns after high-severity fire, tree growth response to the reintroduction of frequent-fire, and tree growth response to multiyear droughts in fire-maintained and fire-excluded forests. We found that high-severity patch locations were more likely to regenerate when positioned downwind, downslope, and near intact forest. Trees had similar growth responses to first-entry fires and reburns following long-term fire-exclusion. After experiencing …

Tnf Prevents Establishment Of Anti-Tumor Immunity And Elucidates Toxicities Following Myxoma Virus Based Oncolytic Virotherapy, Miriam Beatriz Valenzuela Cardenas

Biomedical Sciences ETDs

Tumor Necrosis Factor Alpha (TNF) can lead to tumor regression through its direct cytolytic activity, yet it has also been implicated to facilitate tumor progression. This scenario complicates the efficacy and applicability of TNF based therapeutics as treatment for malignancies. In the context of oncolytic virotherapy (OV) which uses replicating viruses to treat tumors and acts by triggering production of pro-inflammatory cytokines, exploring such mechanisms is vital. Here we show that a Myxoma based oncolytic virus (vPD1/IL12) can induce large amounts TNF. The presence of TNF in the context of vPD1/IL12 plays a detrimental role both for tumor regression by …

Source Detection And Automatic Modulation Classification For Modern Antenna Array Processing, Jayakrishnan Vijayamohanan

Electrical and Computer Engineering ETDs

Source detection and automatic modulation classification are two of the most important steps in any array processing task. In this research a novel deep learning model referred to as RadioNet, is proposed that is focused on solving both these problems by reformulating them as a multi-label classification problem. Traditional approaches to both these topics face challenges in scenarios with noise, interference, fewer number of snapshots, and high number of sources. The limitations of the conventional models are investigated and overcome by the proposed solution. RadioNet is also compared with other existing state-of-the-art machine learning based solutions. The introduced model is …

Trump And China: The Rocky Road Ahead, Mel Gurtov

Politics and Global Affairs Faculty Publications and Presentations

China’s consistent message to the U.S. since Donald Trump’s election is the need for deeper cooperation. But Trump and his hawkish advisers and Congress members seem bent on a trade war and closer ties to Taiwan. His strategy is that once the Middle East and Ukraine are “solved,” he will be positioned to force Xi Jinping’s hand. But the Chinese have options for dealing with U.S. economic pressure. Still, Trump might bargain on U.S. security ties if he can get a deal on trade. The most likely outcome is more tension in U.S.-China relations and a further drift toward Cold …

An Overview Of Gibberellin Inhibitors For Regulating Vegetable Growth And Development, Erik Setiawan, Rahmat Budiarto, Jajang Sauman Hamdani, Mansour Ghorbanpour

Jurnal Kultivasi

Gibberellin (GAs) promotes plant growth processes like germination, shoot elongation, root development, and flowering, while its inhibition is occasionally used in some vegetable crop practices. This paper aims to review the current literature on GAs inhibitors in practical vegetable crops and suggest future strategies for increasing yield. In some vegetable crops, inhibiting GAs with natural (abscisic acid, ethylene) or synthetic (paclobutrazol, prohexadione-Ca) regulators is key to improving yield and quality. Abscisic acid (ABA) counteracts GAs in germination and stress adaptation, while ethylene (ET) opposes GAs in senescence and growth inhibition. The application of paclobutrazol (PBZ) and prohexadione-Ca (Pro-Ca) is known …

Background

Maternal adverse childhood experiences (ACEs) are robust predictors of mental health for both the exposed individual and the next generation; however, the pathway through which such intergenerational risk is conferred remains unknown. The current study evaluated the association between maternal ACEs and infant brain development, including an a priori focus on circuits implicated in emotional and sensory processing.

Methods

The sample included 101 mother-infant dyads from a longitudinal study. Maternal ACEs were assessed with the Adverse Childhood Questionnaire dichotomized into low (0 or 1) and high (≥2) groups. White matter microstructure, as indexed by fractional anisotropy (FA), was assessed …

Investigating Tumor Growth And Regulation In Supratentorial Ependymomas; The Impact Of Dlk1 And Egr1 Knockout, Om Sinojia

Honors Scholar Theses

Ependymomas (EPNs) are primary brain tumors that often arise from radial glial cells lining the ventricular system. Supratentorial ependymomas (ST-EPNs) are particularly aggressive, and understanding the molecular factors driving their growth is critical for developing targeted therapies. This study investigates the roles of DLK1 and EGR1, key regulators in cellular differentiation and tumorigenesis, in the development of ST-EPNs. We utilized genetically engineered mouse models to induce postnatal knockouts of DLK1 and EGR1 and evaluated tumor growth using histological and imaging techniques. Tumor area was quantified across multiple brain sections from both male and female mice. DLK1 knockout brains exhibited consistent …

5-Fluorouracil Induced Oxidative Stress Is Variable Across Triple Negative Breast Cancer Cell Lines, Rachel L. Walker

Departmental Honors & Graduate Capstone Projects

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with treatment limited to chemotherapy. However, not all patient tumors respond to chemotherapy. The variable cytotoxic effects of chemotherapies may be due to how cancer cells regulate reactive oxygen species (ROS). In this study, we examined two mouse breast cancer cell lines: 4T1 and EO771, vary when treated with hydrogen peroxide (H2O2) and 5-Fluorouracil (5FU), known ROS-inducing substances. In 4T1 cells H2O2 increased oxidized DNA but caused minimal cell death. While in EO771 cells that same amount of H2O2 caused complete apoptosis. Cell number, ROS, and cell death showed …

Evaluation Of Electrode Configurations For (0,2) Piezoelectric Ultrasound Transducers, Abdul Qayoum Popal

Mechanical Engineering ETDs

Piezoelectric micro ultrasound transducers (PMUT array) are pivotal in MEMS applications. They typically operate in the fundamental (0,1) acoustic mode and are not significantly researched for higher modes (0,2) and (0,3). Similarly, vibrating mesh atomizers (VMAs) demand the second (0,2) mode and third mode (0,3) for effective aerosol generation, highlighting the need for optimized electrode configurations—a relatively unexplored area. This study presents the first comprehensive analysis of how electrode designs influence PMUT performance in the (0,2) mode for VMA applications.

Utilizing COMSOL multiphysics finite element modeling (FEM) with residual stress considerations alongside experimental validation, we demonstrate that optimized electrode configurations …

Corneal Transplants And Their Impact, Bianca Estrada

Honors Capstones

A corneal transplant, also called keratoplasty or corneal grafting, is a type of surgery where damaged or diseased corneal tissue is replaced by a healthy donor cornea. The first successful corneal transplant was performed in 1905 by Dr. Eduard Zirm, but since then, surgical advancements have developed greatly, leading to more beneficial outcomes. Corneal blindness is a major form of reversible blindness that is manageable with healthy donor cornea transplantation. Other recipients or possible candidates for corneal transplantation include those with keratoconus, Fuchs’ dystrophy, eye infections, or eye injuries. This remarkable surgery is now one of the most common transplant …

Effects Of Modification In Limonene And Geraniol On The Properties Of Thermal Cured Polyurethane Films, Sauravkumar Rajeshbhai Patel

Electronic Theses & Dissertations

The increasing demand for green materials has inspired in-depth research into biobased polymers; among these polymers, polyurethanes stand out because of their widest range of applications: coatings, adhesives, and biomedical devices. The subject of this paper is the preparation of bio-based polyurethane films based on the polyols synthesized from renewable feedstocks such as limonene, geraniol, and soybean oil. Limonene and geraniol were chemically modified from natural sources such as citrus fruits and essential oils to high-functionality polyols. Characterization of such polyols showed that geraniol had the highest hydroxyl (OH) value and thus geraniol-based polyurethane films were highly influencing in reactivity …

3d Game: Enhancing Game Ai With Machine Learning, Nicholas William English

Masters Projects

Machine learning (ML) and artificial intelligence (AI) are terms that are often used synonymously, but they are ever-so slightly different. Machine learning is really a subset of artificial intelligence and involves creating an algorithm so that a computer can learn patterns. Artificial intelligence extends machine learning with the goal to go beyond pattern recognition by having a computer that is capable of mimicking human intelligence. Video games often use the term AI in reference to the bots or non-playable characters (NPCs) that players may interact with. Generally, these bots do not actually implement AI, nor do they use ML, but …

Decentralized And Divided: Philadelphia’S Public Assistance System And Community-Based Initiatives, Gianna Casey, Shari Orisich

Honors Theses

Public assistance programs and community-based initiatives have aided Philadelphian’s residents in a cohesive effort to fill the gaps of community-needs. While both are inherently different in their methodologies and executions, their structures are built upon a collective foundation of legislative principles and policy-based ordinances in Philadelphia. These concepts, first began with poor laws and religious organizations in the 19th century, have turned into a complex system that has fallen tremendously short of sufficiently addressing the specialized needs of Philadelphian families. The surrounding laws for public assistance program administration (e.g. TANF and WIC), are founded within the objectives of these poor …
