An Educated Guess: The Impact Of Education On Conspiracy Theories And Voting, Ellie Bickelhaupt

Student Scholar Symposium Abstracts and Posters

How strongly does education impact one's perception and opinion of conspiracy theories and voting? Throughout the years, conspiracy theories have been a rising trend in recent years that many people find entertaining, but many believe to be actual facts. The impact of one's education level can substantially change a person's beliefs in conspiracy theories and overall trust in the government. This trend has been shown by analyzing media consumption, education status, and the American National Election survey. This research will compare the trends between education level and conspiracy theory beliefs and how both affect a person's voting behavior. This research …

The Moderating Effect Of Socioeconomic Status And Walkability On The Efficacy Of Physical Activity Interventions, Analisa Vavoso, Vincent Berardi, Marc A. Adams

Student Scholar Symposium Abstracts and Posters

To enable physical activity (PA) interventions to better tailor procedures to participant characteristics, we investigated the role of neighborhood socioeconomic status (SES) and walkability on the differential effectiveness of adaptive versus static activity goals (AG vs. SG) and immediate versus delayed (IR vs. DR) reinforcement in a PA trial.

Data was collected as a part of the WalkIT Arizona study, where healthy, inactive adults (n = 512) were instructed to wear an accelerometer daily for one year and were provided with daily goals for moderate-to-vigorous PA (MVPA). The intersection of goal types (adaptive and static) as well as reinforcement types …

Factors In Decision Making Of Political Candidates, Levi Ramirez Garcia

Student Scholar Symposium Abstracts and Posters

What factors impact the decision to run as non-partisan over one of the major US parties? It is essential to analyze this phenomenon to determine the real motivations of candidates and the party they represent because they impact society as a whole. The candidates' ideologies and how the candidates feel representing the parties' ideologies are the main reasons for choosing non-partisan over one of the major US parties. This occurs because humans tend to work where they feel comfortable and in places with the same values and ideologies as them. It is the same in the case of candidates; they …

The Contemporary Causes Of Americans' Fear Of Illegal Immigration, Amilie Cai

Student Scholar Symposium Abstracts and Posters

Annually, the U.S. aspires to extend its liberality by opening its border to more than ten thousand refugees. In this paper, I examine how political party identification, census region, and internet usage influence U.S. adults' fear of illegal immigration. Relying on the 2023 Chapman Survey of American Fears, a representative national sample of U.S. adults, I find that political party has remained a consistent predictor for an American’s fear of illegal immigration, with people who align themselves with the Republican Party in 2022 being more afraid of illegal immigration compared to other political parties, such as the Democrat Party. In …

Computational Linguistics And Multilingualism: A Comparative Analysis With Spanish And English Data, Evelyn Lawrie

Student Scholar Symposium Abstracts and Posters

Computational linguistics is an increasingly ubiquitous field, serving as the basis for artificial intelligence and machine translation. It aims to analyze the syntax and semantics of individual words and phrases. While there have been in-depth advancements in computational linguistics strategies for the English language, others have not been developed as thoroughly. This lack of emphasis on multilingualism has contributed to the disappearance of Hispanic perspectives in the digital world. Especially those of indigenous heritage, as the decline of many indigenous languages has been exacerbated by the lack of digital translation services. Sentiment analysis is a branch of computational linguistics that …

A Content Analysis Of Common Relationship Challenges Among People Who Practice Polyamory, Kalyn Su, Sophie Camilleri

Student Scholar Symposium Abstracts and Posters

Approximately 1 out of 9 people in the U.S. have engaged in polyamory (Moors et al., 2021), a relationship type in which all involved agree to have multiple romantic and/or sexual partners. Despite the commonness of polyamory, there are many misconceptions about the polyamorous experience. However, research has yet to examine common challenges that people engaged in polyamory endure. The goal of the present qualitative study was to identify the disadvantages and stressors of polyamory in order to shed light on the unique experiences of people in these relationships. 219 adults who were currently in a polyamorous relationship were asked …

The Gender Divide: Exploring Gender Patterns Of Perceived And Realistic Risks Of Murder By Unknown And Known Perpetrators, Haley Forth

Student Scholar Symposium Abstracts and Posters

In a society where vulnerability is often associated with femininity, women are depicted as helpless victims, which in turn underscores the gendered challenges faced by both men and women. It is thought that gender disparities among women increase the likelihood of fear and risk of murder victimization. Rather, both men and women face homicide at significant rates where gender vulnerability is correlated to different types of violence. In this paper, I examine the complexities of gendered perceptions of perceived and realistic risks behind the fear of being murdered by someone you know and murdered by a stranger. Relying on the …

Spatiotemporal Gait Parameter Consistency Across Two Days Of Treadmill Walking In Stroke Survivors, Alejandro Aguirre Ramirez, Samantha N. Jeffcoat, Natalia Sanchez, Andrian Kuch

Student Scholar Symposium Abstracts and Posters

Retraining impaired gait is essential in post-stroke recovery. This project aims to determine between day variability of spatiotemporal gait measures in treadmill walking post-stroke to differentiate between changes due to the intervention and measurement errors due to between day test-retest variability. Six individuals post-stroke performed a two-minute walk test at a self-selected speed (SSS) for two consecutive days. SSS was assessed through the six-minute walk test. Reflective markers were placed on anatomical landmarks (van den Bogert et al. 2013). The heel markers were used for step detection. We calculated spatiotemporal parameters: stride length, stride time, step length, stance time, and …

"And Then There Were None:" The Silencing And Censorship Of Translated Works Under Francisco Franco, Avery Austin

Student Scholar Symposium Abstracts and Posters

We tend to live under the assumption that translations will always attempt to be faithful to their original texts, blindly believing in the infallibility of the translator. However, in doing so, we ignore how translation can be used to take advantage of the reader – how can one know that a change has occurred in a translated work if they have no knowledge of the text’s original language? This paper studies the power dynamics of translation, and how it can be used as a tool to aid censorship. By focusing on translated literary works under the Franco regime, this work …

La Gentrificación: Un Estudio Comparativo Entre La Ciudad De Santa Ana, California Y La Ciudad De México, Evelin Delgado

Student Scholar Symposium Abstracts and Posters

Gentrification has increased within the latino community. Two examples of this process occurring today include cities like Santa Ana and Mexico city. Capitalistic views facilitate gentrification as companies with more purchasing power are able to buy areas and maintain their ability to stay there. Residents from Mexico city and Santa Ana provide their side of the story of the changes they are witnessing and how they are being affected. The globalization of businesses has further facilitated the process of gentrification as companies are motivated by capital led development in urban spaces. After Mexico signed the NAFTA, WTO, and OECD, it …

Artistic Resistance Under Dictatorships In Spain And Argentina Through The Lens Of Communication Theory, Adrian Self

Student Scholar Symposium Abstracts and Posters

Under dictatorships in Spain and Argentina, artists used their mediums to criticize the actions of the Catholic church and oppressive conditions enforced by the government, using allegories, metaphors, and symbolism in their art. While many artists tried to create works that fell within authoritarian guidelines, others intentionally created cinema and literature criticizing the Argentine and Spanish governments, values, and practices, knowing the works would be banned. This investigation uses examples of cinema and literature created and published deliberately to be prohibited or censored under the regimen of Francisco Franco from 1939-1975 in Spain or the last civil-military dictatorship from 1976-1983 …

Golf’S Civil War: The Antitrust Lessons To Learn From The Pga Tour’S Rivalry With Liv Golf, Nic Vandeventer, Associate

Vanderbilt Journal of Entertainment & Technology Law

The regulation of professional sports leagues under the Sherman Act presents a unique and, up to this point, unsolved problem. Increased regulation of the United States’ beloved sports is not something that many US citizens would necessarily welcome. And yet, courts are consistently confronted with the dilemma of checking competition “off the field” while attempting to leave unaffected the competition “on the field.” In doing so, courts must reconcile the principles and objectives of the Sherman Act (the Act) with the restraints necessary for the success of sports as an enterprise. While mirroring some of the aspects of traditional trade …

Gender Pay Equity: An Analysis Of The United States Women’S National Team Soccer Settlement, Joni Hersch, Delaney M. Beck

Utah Law Review

Even though the United States Women’s National Team (“WNT”) has been far more successful than the United States Men’s National Team (“MNT”), the team members have experienced unequal treatment from the United States Soccer Federation (“USSF”) since its inception. In March 2019, members of the WNT filed suit against USSF, alleging that it had violated the Equal Pay Act (“EPA”) and Title VII of the Civil Rights Act of 1964. The complaint alleged that USSF had a policy of discriminating against the WNT due to their players’ gender by paying them less than the MNT and providing them with lesser …

Development Of A Model To Predict Maximum Crack Width And Spacing In Reinforced Concrete Beams Under Flexural Stress, Saeed Alghamdi

Theses and Dissertations

Cracking in reinforced concrete structures is unavoidable due to the low tensile strength of concrete. Even though minimizing cracks on exposed concrete surfaces is significantly important from the aesthetics point of view, it is also very important for the durability and overall performance of the structure.

Flexural members must be designed to minimize cracking that may occur during the structure's service life. Even though there has been a lot of experimental work on crack width over the last several decades, a literature review reveals that researchers still can't agree on which variables are most important. Part of the reason for …

Unraveling The Physics Of Quasar Jets Using Hst Polarimetry, Devon Clautice

Theses and Dissertations

We present a multiwavelength study of three high-power FR II (quasar) jets -- 3C 273, PKS 0637-752, and 1150+497 -- with an emphasis on new high-quality Hubble Space Telescope (HST) optical polarimetry and Chandra X-ray Observatory imaging. Relativistic jets from active galactic nuclei transport energy and mass from the supermassive black hole’s accretion region out to Megaparsec-scale lobes, with effects that feedback into galaxy formation and cluster energetics. We build on recent work which has called into question our fundamental understanding of FR II jet physics, and suggest that highly-efficient particle acceleration must be taking place in situ …

Test And Evaluation Model For Midwater Docking Of Autonomous Underwater Vehicles, Parker Baillon

Theses and Dissertations

This research created a Test and Evaluation (T&E) model for midwater Autonomous Underwater Vehicle (AUV) capture. The creation of this model will allow for a better assessment of the feasibility of midwater AUV capture. To achieve this, the T&E model was exposed to various flow conditions to assess stability. Capturing an AUV in midwater, the area below the wave-affected zone to the sea floor, has many benefits for an AUV and its mission. AUVs basing missions from a midwater dock will not be affected by wave motions. A midwater dock can be transported to any mission site and deployed with …

Improving Static Cold Storage Life Of The Human Heart Before Transplant, Juan Sebastian Rodriguez Paez

Theses and Dissertations

Organ storage and transportation are critical steps for the success of organ transplantation. Static cold storage (SCS) of hearts for heart transplantation (HTx) remains the standard approach. However, SCS may involve damage to the tissue resulting from extended hypothermic preservation, potentially affecting organ viability. More over, the temperature distribution on and within the heart is unknown during heart transplantation. Therefore, there is an interest to study different stages of the heart transplantation process towards determining the 3D temperature distribution on and within the heart. There could be a possibility of having a hypothermic injury in different parts of the heart …

Methodologies For Optimization And Surface Heat Flux Estimation For Hybrid Thermal Protection Systems, Syed Arafun Nabi

Theses and Dissertations

Thermal protection system (TPS) plays a pivotal role in safeguarding space vehicles from extreme aerothermal heating during atmospheric entry. To ensure effective thermal management, Hybrid Thermal Protection seamlessly integrating both active and passive TPS is an innovative solution. The passive TPS consists of an insulative layer on vehicle skin to counteract the aerothermal heat. Although a thicker layer enhances insulation, a trade-off arises between the thickness of the passive layer and the spacecraft’s weight. Beneath the passive TPS layer lies the active TPS functioning as a heat exchanger where the vehicle fuel liquid is considered as coolant. The effectiveness of …

Investigating The Relationship Between Metacognition, Motivation, Self-Regulation Strategy Usage, And Physical Activity Participation, Kay Sharon Stanfield

Theses and Dissertations

There are numerous benefits associated with physical activity. Unfortunately, few people participate in enough daily activity to reap the rewards. Health professionals have explored ways to promote adherence to physical activity and healthy behavior. Evidence shows self-regulation to be a determinant of physical activity. This study investigated the relationship between self-regulation strategy usage and levels of physical activity participation. Additionally, the study examined how motivation (through the perspective of Self-Determination theory) impacts physical activity. Six behavior regulation styles correspond to the degree of motivation (from low to high) on the Self-Determination continuum. A comparison of behavior regulation styles to physical …

Artificial Neural Networks As The Solution Of Inverse Heat Conduction Problems In Multidimensional Domains, Andrea Carolina Martinez Mundarain

Theses and Dissertations

Surface heat flux measurement is essential in various industrial applications including atmospheric entry of space vehicles, machining processes, non-destructive testing and more. While direct measurement of surface heat flux is known to be a very difficult, if not infeasible, task, acquiring temperature measurement from sub- surface locations are often viable. The problem of evaluating the surface heat flux using internal temperature measurements is known as an inverse heat conduction problem (IHCP). IHCPs are considered as mathematically ill-posed as they are highly sensitive to measurement error. This research presents a solution based on the implementation of artificial neural networks (ANNs) to …

Investigating Endothelial Damage During Ischemic Stroke Treatment Using In Vitro And Computational Models, Zackary Lorton
