UTAH'S HERITAGE: A LITTLE KNOWN STORY OF MORMONISM AND EUGENICS

March 21, 2024 12:00 AM
Authors: Lindsay Beekman. Mentors: Olga Kopp. Insitution: Utah Valley University. This research probes the primary historical newspapers of early 1900s Utah, providing insights into the cultural atmosphere of the time and the widespread support for the Eugenics movement throughout the state. Our findings indicate that out of 72 distinct newspaper articles discussing Eugenics in Utah between 1908 and 1938, 62 conveyed a positive perspective, 9 remained neutral, and only 1 expressed opposition. Notably, from 1947 to 1996, leaders of The Church of Jesus Christ of Latter-Day Saints administered the ‘Indian Student Placement Program’ or ‘Lamanite Placement Program,’ aligning with many Eugenics principles. Utah, like many places worldwide, embraced Eugenics with open arms.

Investigating the Utility of Avatars and Actors in Undergraduate Psychology Role-Play Exercises

March 21, 2024 12:00 AM
Authors: Kennedy Parker. Mentors: Melinda Russell Stamp. Insitution: Weber State University. Role-playing is considered one of the most effective teaching strategies for training undergraduate clinical psychology students because it fosters active learning in a supportive and safe environment (Gibbs, 2019; Osborn & Costas, 2013). The literature is replete with studies that document the benefits of role-playing for clinical training. These benefits include the development of active-listening, perspective-taking, empathy, critical thinking, communication, collaboration, problem-solving, and increased enjoyment of course material (Dawood, 2013; Gibbs, 2019; Grose-Fifer, 2017). A challenge associated with classroom role-plays involves student reluctance to participate due to feelings of self-consciousness and anxiety associated with being negatively evaluated (Mallonee, 2018). There is limited research on the effectiveness of different role-play modalities which may include classmates role-playing with one another; as well as actors and virtual avatars role-playing with students. There have been mixed findings in the literature regarding whether students are more comfortable disclosing to virtual avatars or to actors in face-to-face encounters (Rogers et al., 2022; Roster & Chen, 2016). To date, there are no research studies comparing student perceptions of role-plays with virtual avatars to face-to-face interactions with actors in undergraduate psychology classes. For the current study, 60 undergraduate Psychology students were randomly assigned to either role-play with an avatar or an actor. Following the 25-minute role-plays, students completed surveys assessing perceived utility value, self-efficacy, level of anxiety, engagement, and future interest in role-playing. This preliminary study will compare the effectiveness of avatar and actor role-play modalities which will help educators better structure training for undergraduate students in clinical psychology.

Creating a universal framework for reconstructing phylogenies: Building trees at your fingertips using R

March 21, 2024 12:00 AM
Authors: Barbara Jetton, Carl E Hjelmen. Mentors: Carl E Hjelmen. Insitution: Utah Valley University. This project’s emphasis is the creation of an accessible and reusable tool to be used in broader scientific inquires of evolutionary relatedness. As of January 2023, GenBank contains 2.9 billion nucleotide sequences representing 504,000 distinct species. Despite this abundance of data, comprehensive and up to date phylogenies are lacking, impeding investigation into genetic histories and trait evolution. To address this problem, I am developing an open-source pipeline to expedite the construction of these evolutionary trees. I have a specific aim of creating a phylogeny for the order Diptera (flies) in order to investigate the evolution of the chromosome numbers for over 2500 species with chromosome count data on karyotype.org. I use R code, and the packages “reutils”, “ape”, and “seqinr”, to create reusable universal scripts which pull accession numbers from NCBI GenBank for each species based on the requested gene names. A second script was built to use the curated accession numbers to pull FASTA sequence data for each gene and write a multi-FASTA file for each gene, resulting in a comprehensive dataset necessary for alignment and phylogenetic tree construction. This effort will result in updated insights on the evolutionary history of Diptera related to chromosome numbers and can be used in further research in comparative biology. Additionally, these scripts can be used to investigate and reconstruct phylogenetic information for any species group with sequence data available on GenBank.

Detection of Beet curly top virus in Utah plants

March 21, 2024 12:00 AM
Authors: Elise Bennett, Megan Frisby, Rob Hess, Max Taylor, Erin Riggs, Alma Laney. Mentors: Alma Laney. Insitution: Utah Valley University. Beet curly top virus (BCTV) is a highly destructive virus found in most of the Western United States characterized by curling of the leaves, yellowing, and lack of produce. Historically, BCTV was a key factor in the decline of sugar beet production in Utah, formerly a large factor in the state economy. Commonly found in beets, tomatoes, and peppers, BCT is vectored by the beet leafhopper, Circulifer tenellus, as it feeds on the phloem tissue. Novel hosts of this virus found in Utah include sunflower, mallow, eggplant, hemp, big sagebrush, and Solanum jamesii, the Four Corners potato. Sunflowers showed symptoms of curled leaves and stunting. Similarly, the eggplant developed shriveled leaves and a mosaic at the leaf tips. Four Corners potato, a staple food source of the Indigenous peoples of the Southwest, displayed strong symptoms including stunting, leaf yellowing, and leaf curling. Weedy species and other garden plants displaying various viral symptoms were also collected for testing. Detection was done using published BCTV detection primers and rolling circle amplification with the use of Phi29 polymerase to prepare the genome for whole genome sequencing. A 518 bp region was sequenced to 4x coverage from eight host samples. To ensure the validity of diagnosis, a triple antibody sandwich ELISA was performed confirming the results. Considering the history of BCTV in relation to the agriculture industry of Utah, the discovery of novel hosts is cause for concern since this virus is adaptable and limits crop yield. The diagnosis of BCTV in native plants, such as the Four Corners potato and the big sagebrush, is pressing as it these local flora are unique to the region. The verification of BCTV in these novel hosts allows for the agriculture industry of Utah to prepare prevention methods including the monitoring of beet leafhoppers and increased integrated pest management strategies are needed to protect our local environment.

Leveraging Machine Learning in Face Mask Formulation

March 21, 2024 12:00 AM
Authors: Alexander Goslin, Hazel Ticas, Morgan Covarrubias. Mentors: Daniel Scott. Insitution: Utah Valley University. In the evolving realm of personal care product development, striking a balance between ingredient choice, manufacturing intricacies, and consumer demands is pivotal. As the industry grapples with escalating costs and the clamor for novelty, there's an imperative to find methods that refine the development pathway, keeping both product quality and cost-effectiveness in check. Machine Learning (ML) emerges as a promising contender, proposing a data-centric route to formulation - from discerning patterns to forecasting efficacies, and even creating formulas themselves. This study delves into the intricacies of leveraging ML for personal care formulations, specifically emphasizing its role in substituting ingredients to either amplify a product's qualitative facet or reduce production costs. Despite the allure of ML, its integration into personal care isn't without challenges, given the industry's unique regulatory, consumer-centric, and trend-driven landscape. Through rigorous testing, evidence-based enhancements, and in-depth analysis, we aim to shed light on ML's functional dynamics in cosmetic formulations, underscoring both its potential dividends in cost and quality.

Green Hydrogen Production from Wastes by High Temperature Plasma Pyrolysis

March 21, 2024 12:00 AM
Authors: Veronica Gunyan, Minh Nguyen. Mentors: Kevin Shurtleff. Insitution: Utah Valley University. Our team’s project green hydrogen production from plastic waste by high temperature plasma pyrolysis aims to help aid in reducing waste by taking UVU’s recycled plastic waste, decomposing it using plasma pyrolysis, and turning it into clean hydrogen and carbon in a cost-effective manner. Pyrolysis is the thermal decomposition of organic materials in an oxygen-free zone. Green hydrogen comes from renewable energy and releases no CO2 by products into the air. The purity of the hydrogen can be improved by adjusting components such as temperature in the reactor, range, the gas used, the time frame, catalysts and other operational elements. Energy prospects can be determined by considering the energy consumed subtracted by that produced to determine the net output.

Improved low-cost, solar water purifier to reduce clean water scarcity

March 21, 2024 12:00 AM
Authors: Fatoumata N'diaye, Kevin Shurtleff. Mentors: Kevin Shurtleff. Insitution: Utah Valley University. The use of solar energy for water purification purposes has proven to be an efficient tool with promising results which could help tackle the issue of water scarcity in developing regions of the world. The low-cost, solar water purification system built previously will be improved through increasing thermal conduction, enhancement of the water flow uniformity, strengthening of the piping system, increasing airflow inside the water purification system, and thus maximizing the clean water production rate. We used aluminum foil as the condensation surface with silicone caulk as a binding agent between the materials. We used ultra-violet resistant greenhouse plastic film to protect the purifier overall from sunlight damage. We measured the incident solar irradiance, airflow inside the purifier, temperature of the evaporation side, temperature of the condensation side, ambient temperature outside, conductivity of the dirty and clean water, and clean water quality/taste. Finally, we compared this data to previously collected data.

"Cognitive Insights into Madagascar Hissing Cockroaches: Memory, Learning, and Motivated Behavior"

March 21, 2024 12:00 AM
Authors: Brandon Barlow, Ethan Reese, Victoria Vazquez, Abbi Stark, Monica Sanchez, Alex Wilson, Rain Evans, Josef Becker, Amy Chevrier, James Taylor. Mentors: James Taylor. Insitution: Utah Valley University. This study focuses on memory and learning observed in Madasgascar Hissing Cockroaches (MHC). Research on insects can be used to inform our understanding of behavior and cognitive processes and add to our existing knowledge about the studied species. While there is existing literature focused on memory and learning in many insects, cockroaches are often chosen as a model due to their adaptability, resilience, and availability. Little research on MHC currently exists, especially in regard to memory and learning or drug seeking behaviors. This study uses a mixed model design, looking at arm choice percentages and latency to choose, between the control and experimental groups and comparing trials for each subject. In earlier trials, MHC demonstrated behavior that indicated they had learned not to fear light, a naturally aversive stimulus for cockroaches. Building on data collected in earlier trials, we developed a new protocol to evaluate the MHC associative learning behaviors and to test drug-seeking as a motivated behavior. Subjects are individually tested in a T-shaped apparatus in which they have to choose an arm to go into or are timed out. Each arm has a specific reward, either a sucrose and ethanol solution (experimental group) or plain sucrose solution (control group) in the left arm, and plain sucrose solution (experimental group) or water (control group) in the right arm. Each subject is run 2 days (6 trials per day) in these conditions, and then 3 days with the left arm lengthened to test if the subjects will seek their preferred reward even if it requires traveling a greater distance.

Does Greater Phylogenetic Distance Affect Competition Outcomes in Fungal Communities?

March 21, 2024 12:00 AM
Authors: Joshua Stubbs, Annette Lewis, Kendall Holcomb, Barbara Suassuna Schincariol. Mentors: Geoffery Zhan. Insitution: Utah Valley University. Does Greater Phylogenetic Distance Affect Competition Outcomes in Fungal Communities?Annette Lewis, Kendall Holcomb, Bárbara Suassuna Schincariol, Josh Stubbs, Geoffery Zahn PhDFungi play a critical role in decomposition, affecting nutrient cycling at a global scale. Saprotrophic fungi competitively decompose dead organic matter. However, the role of phylogenetic relatedness on interspecific competition in fungal communities has not received much attention. The theory of phylogenetic over-dispersion suggests that species within a community tend to be less related than expected by chance, therefore limiting competition due to functional redundancy. Similarly, Darwin’s naturalization hypothesis suggests that taxonomically distinct invaders might experience reduced competition and resistance. In this study, we chose three different saprotrophic fungal species with varying relatedness: Aspergillus niger and Fusarium keratoplasticum (from the same family), and Pleurotus ostreatus (from a different phylum). These species were chosen based on decomposition abilities and phylogenetic distances. These species were cultured and placed in seven combinations to assess their ability to decompose and compete as individual fungal populations and as combined communities (e.g., A, B, A+B, B+C, and A+B+C). Each species was placed near a sterilized piece of paper such that competition was evaluated by analyzing the paper coverage in Petri dishes over three weeks. Each Petri dish was analyzed individually based on the average percentage of paper covered and, within combined communities, the percentage of paper each species covered. Interactions between each species and the percentage of the paper covered was recorded for further analysis. Assessing paper coverage allows for the observation of any potential competitive inhibition of decomposition. We hypothesize that decomposing and competitive abilities would be the strongest with A. niger. Despite the fast growth rate of A. niger individually, preliminary results suggest that it was outcompeted when paired with other species. This research highlights the potential nuances in fungal community interactions influenced by phylogenetic relationships, shedding light on the principles of phylogenetic overdispersion and Darwin’s naturalization hypothesis.

Investigating the relationship between natural environment and drosophilid genome size.

March 21, 2024 12:00 AM
Authors: Samantha Curnow, Carl Hjelmen. Mentors: Carl Hjelmen. Insitution: Utah Valley University. The genome sizes of insects vary immensely; some insects have only 100 million base pairs, while others reach nearly 18 billion base pairs. Many selective pressures can have an influence on genomes, but we still lack a clear understanding of which selective pressures cause such variation in genome size even within well-studied groups. To determine the influence of environmental factors on this variation, we investigate the relationship between genome size and the average natural environment of 152 Drosophila species. The nature of the relationship between genome size and environmental factors is investigated using phylogenetic models and linear analyses such as phylogenetic generalized least squares analysis. We collected data from peer-reviewed papers and publicly available datasets, such as karyotype.org and WorldClim, to compare the genome size of each species to the temperature, altitude, humidity, etc. of their natural environments using linear phylogenetic models. The distribution of these species was also visualized using geographic and biological analysis packages in R, such as geodata, to extract environmental data of specified regions, and phytools in combination with caper to run phylogenetic comparative analyses.

Assessing Genomic Diversity Via whole genome resequencing in bean cultivars (Phaseolus L. spp.) from Brazil, a putative secondary center of diversity.

March 21, 2024 12:00 AM
Authors: Kaycie A Melville, Ashley N Egan, Yu Ya Liang. Mentors: Ashley N. Egan. Insitution: Utah Valley University. Phaseolus vulgaris (common bean) and P. lunatus (lima bean) provide protein and nutrition for millions of people across the globe. Native to the New World, these cultivated species present unique histories of multiple and independent domestications in Mesoamerica and the Andes. Brazil is the leading producer globally of these beans. With both wild and cultivated landraces present, Brazil may act as a secondary center of domestication for these two economically significant leguminous crops. Brazil's indigenous populations’ cultivation efforts may include both wild and cultivated germplasm, potentially contributing to the continued domestication of these crops to create novel shapes, sizes, and colors that are grown and hand-selected by the natives in these regions. To investigate Brazil as a secondary domestication center of beans, this research addresses several key questions: Are signals of past and current domestication processes discernible in current Brazilian cultivars of these species? Can we unravel the relationships between these Brazilian crops and their primary centers of domestication? What genetic differences are underpinning domestication? How diverse are Brazilian cultivars? How do they relate to wild and related material and species? This work focuses on 48 accessions of P. lunatus and P. vulgaris from Brazil, including wild material and two accessions from two related species, P. polystachios and P. filiformis from North America. Whole genomes were resequenced using Illumina sequencing and compared against the published genome of Phaseolus vulgaris to identify SNPs in each accession. Whole chloroplast genomes were also assembled and compared. Phylogenetic analyses, network analyses, population structure, and tests for neutral and positively selected mutations were conducted, revealing distinct clades for both P. vulgaris and P. lunatus with clear links to their Andean and Mesoamerican origins. Genetic diversity was assessed both within (cultivated vs wild) and between P. vulgaris and P. lunatus, demonstrating significant variations, not only between species but also within each species, suggesting the influence of diverse selection pressures and local adaptation during the domestication process. McDonald-Kreitman tests analyze and locate possible domestication genes from the library of SNP’s between outgroups (Phaseolus filiformis and Phaseolus polystachios) and between species. Overall, this research advances our understanding of the intricate process of domestication in P. vulgaris and P. lunatus, highlighting potential ongoing domestication in Brazilian cultivars, unraveling their genetic relationships, and shedding light on the complex interplay of genes that underpin domestication and diversity. These findings contribute to the broader understanding of crop evolution and have practical implications for crop improvement and conservation.

Identifying and Monitoring Groundwater and Surface Water Interactions Utilizing UAVs and Remote Sensing Applications in Wetlands in Utah Lake, Utah

March 21, 2024 12:00 AM
Authors: Anna Wilkinson, Feyan Hoffman, Roshan Abraham. Mentors: Daren Nelson. Insitution: Utah Valley University. Remote sensing technologies, involving drone and satellite imagery, have recently begun to be used in hydrologic research with various applications. The technology is relatively easy to obtain, is noninvasive, and helps minimize cost, access, and safety concerns related to the study of wetlands. The thermal and multispectral imagery can provide unique datasets that expand understanding into groundwater and surface water interactions. As part of this project, we are exploring remote sensing applications within the hydrology of wetlands surrounding Utah Lake, a large freshwater lake within Utah Valley. The project has involved the collection of thermal and multispectral drone imagery from 2021 to 2023. Thermal imagery collected in these areas has assisted in the determining of hot and cold spring locations and how these springs have shifted due to changes in groundwater levels and lake levels. In addition, this imagery has shown how physical anthropogenic influences have also impacted the location and stream channels associated with these springs. Multispectral imagery is used to understand the health of phreatophytes near the lake during dry and wet years to be used as an indicator for groundwater level changes. Even though much of the data is still preliminary and part of a long-term study these remote sensing technologies are already showing how these groundwater systems adapt to seasonal and anthropogenic changes.

Sound Levels on the UVU Pedestrian Bridge

March 21, 2024 12:00 AM
Authors: Jacob Sampson, Joshua Goates, Brian Patchett, Abolfazl Amin, Bonnie Andersen. Mentors: Bonnie Andersen. Insitution: Utah Valley University. Noise from an interstate can reach extreme levels. The OSHA limit for when sound becomes dangerous for the health of individuals is 85 dB. At UVU there is a pedestrian bridge that goes over I-15 and the students and other pedestrians that use this bridge are exposed to sound levels that could be potentially dangerous for their hearing, along with other adverse health effects due to sound on a regular basis. Sound levels have been measured on the bridge using two different measuring devices. The first being an Extech noise dosimeter, that was worn on the shoulder of the measurer as they walked across the bridge. The second instrument used was a Larson David sound level meter. That was placed on several places along the length of the bridge at set to record for several minutes to get the sound levels at those places. Sound levels that have been recorded have ranged form 79 dB to 102 dB. The OSHA limit for occupational exposure at 100 dB is two hours while for non-occupational exposure it is only 15 minutes. This research seeks to better understand and quantify the noise exposure pedestrians experience on the bridge. Also this research hopes to find out what facts influence the sound levels on the bridge and we hope to compare our experimental results to an ANSYS model of the bridge to confirm our findings.

Kynurenine Deamination and Synthesis of Xanthommatin

March 21, 2024 12:00 AM
Authors: Stephen Chamberland, Craig D. Thulin, Katherine Solorzano, Cassandra Beddes, Nathan Twitchell, Abram Caruso. Mentors: Steve Chamberland, Craig D. Thulin. Insitution: Utah Valley University. This investigative procedure is a continuation of an experiment done by UVU undergraduate student Kyra Banks and her mentor, UVU Professor of Chemistry Craig Thulin, to determine the structure of xanthommatin. Xanthommatin is one of the primary pigments found in monarch butterflies, and many other insects. Data obtained during the mass spectrometric analysis was observed to indicate a possible deamination of xanthommatin, however the quantity of deaminated xanthommatin observed was too small and so the structure could not be determined. The research investigates the precedented deamination of kynurenine as a model to develop a procedure for the deamination of 3-hydroxykynurenine, primarily due to the fact that it is cheaper in price to xanthommatin, as well as a chemical precursor that can be used for the synthesis of xanthommatin. The implications of this suggest that the deamination procedure developed for 3-hydroxykynurenine could be successfully replicated with xanthommatin. After the deamination procedure has been successfully repeated, xanthommatin will be synthesized using one of a few procedures developed by Kumar, A., et al1. Once a sufficient sample of xanthommatin has been successfully synthesized, the deamination procedure will be repeated on samples of xanthommatin to determine the structure of deaminated xanthommatin using NMR spectroscopy. The research conducted here is beneficial not only because it is a continuation of other UVU student’s and staff’s work, but also to those whose work is in the animal biology realm of science. The information that will be extracted from this research will spearhead new research pathways and questions to be explored.Xanthommatin-Based Electrochromic Displays Inspired by Nature (acs.org)Biomimetic Colorants and Coatings Designed with Cephalopod-Inspired Nanocomposites (acs.org)

Deciphering the Impact of Pomc Mutation on Mouse Reproductive Behavior: A Comprehensive Data Analysis Approach

March 21, 2024 12:00 AM
Authors: Lauren Silvatti.. Mentors: Zoe Thompson. Insitution: Utah Valley University. Proopiomelanocortin (Pomc) deficiency, stemming from a mutation in the Pomc gene, presents a myriad of health challenges, including extreme hyperphagia, early-onset obesity, and infertility. This study leverages a mouse model exhibiting Pomc-deficiency to delve into the root causes of infertility. While the correlation between obesity and fertility is well-established, our primary focus is to discern whether the POMC mutation independently contributes to reproductive challenges. Our investigation extends into the interplay of genetics, endocrinology, and obesity through data analysis using R, with an emphasis on deploying advanced statistical models.Video recordings of sexual behavior interactions have been analyzed manually, with independent observers marking each behavior. The frequency and duration of each behavior will be compared among three groups of pairings: wildtype-wildtype, heterozygote-heterozygote, and homozygous POMC-deficient mice. Techniques will include data cleaning, timestamp manipulation, and behavior categorization in R, a programming language commonly used for data analysis. To discern patterns and variations, our analysis will also employ statistical models such as linear mixed-effects models. We can account for potential confounding variables and significant differences in durations of previously identified important reproductive behaviors. Visualization tools, including box plots and violin plots, will provide an initial glimpse into the distribution of behavior durations. Subsequently, we plan to conduct inferential statistics, employing techniques such as Analysis of Variance (ANOVA) to assess the significance of differences across multiple groups. Our investigation extends beyond descriptive statistics, with a focus on predictive modeling. Regression analyses will explore potential relationships between behavior durations and reproductive success. Machine learning algorithms will be applied to uncover complex interactions within the dataset.The anticipated results promise not only a nuanced understanding of the interplay between Pomc mutations and reproductive challenges but also the identification of potential biomarkers or predictors of successful reproduction. This comprehensive statistical approach contributes significantly to the fields of genetics, endocrinology, and obesity research, offering a robust framework for future investigations into the intricate relationship between genotype and behavior.

The ABC conjecture and Mason's Theorem

March 21, 2024 12:00 AM
Authors: Juan Palencia, Tanner Probst, Clair Yeaman. Mentors: Machiel Van Frankenhuijsen. Insitution: Utah Valley University. Abstract: The ABC conjecture is an unsolved problem in mathematics first formulated by Joseph Oesterlé and David Masser. The conjecture attempts to show an analogy between polynomials and integers. This insight arises from the Stothers-Mason Theorem (also known as Mason’s Theorem). The theorem states that the maximum degree of a polynomial is always equal to or less than the number of distinct roots minus one. The ABC conjecture attempts to bridge this analogy by defining the height as the maximum algebraic number in the sum a + b = c where a, b and c are relatively prime. Masser and Oesterle define the radical as the sum of log p where p divides abc. Mason’s theorem states that the height is less than the radical minus one. It turns out that this is not true for the integers. Thus Masser and Oesterle formulated a conjecture which may be true. Over the past decades, this inequality has been strengthened and reformulated. Shinichi Mochizuki has recently published what he claims to be a proof of the conjecture, but many mathematicians are currently still working to understand it. The aim of our research is to better understand the height and radical in the ABC conjecture. In addition, we intend to explore the possibilities of expanding the Stothers-Mason Theorem. Since the ABC conjecture is concerned with an analogy between commutative rings (integers and polynomials), we are interested in seeing whether Mason’s Theorem for polynomials also holds for non-commutative rings, such as matrix rings and the ring of quaternions. In addition, we intend to explore the connection between the factorization of polynomials and finite Abelian groups.

Identifying and photographing the instars of a parthenogenetic mayfly (Centroptilum trianguilfer; Ephemeroptera)

March 21, 2024 12:00 AM
Authors: Heidi Kipp, Annika Jones, . T. Heath Ogden. Mentors: T. Heath Ogden. Insitution: Utah Valley University. The purpose of this research is to identify and document mayfly instars from a parthenogenetic population of individuals being raised in the lab. Instars are the developmental stages of an arthropod between molts. Mayflies (and other non holometabolous insects) go through incomplete metamorphosis, moving from egg to nymph stages, and then to subimago (unique to mayflies), and imago (or adult). Previous research indicates the number of instars to be between 12-45 depending on the species, and the species we studied is estimated to have around 15. During each instar, mayflies shed their exoskeleton. The difference between each instar is vital to understanding the changes in gene expression and overall life cycle of a species. Instars have subtle differences, and identifying them will help further research into which genes are involved in producing specific morphological characteristics. Defining these structures, such as the forming of eyes or wings, are of particular interest in evolutionary phylogenetics. We raised Centroptilum trianguilfer (Ephemeroptera: Baetidae) in a controlled water tank, collecting and dating egg samples from mature imagos. Water is maintained with standard ion composition with 130-400 conductivity. Once the eggs hatched, we performed daily inspections and measurements using a 40x stereomicroscope microscope and Lumenera Infinity Analyze. We are using basic appearance, size and morphology) to separate instars. We will identify and photograph each instar. Samples from the different instars, subimagos, and adults will be acquired and used to generate transcriptome data. We propose that our research will aid in the investigation of mayfly evolution and their genetic mechanisms of control.

Methods for assessing Ephydra gracilis populations across Great Salt Lake

March 21, 2024 12:00 AM
Authors: Cora Rasmuson, Carly Biedul, David Herbst. Mentors: Carly Biedul. Insitution: Westminster College. Great Salt Lake (GSL) is a unique ecosystem known for its elevated saline conditions, supporting diverse biological communities. However, GSL's vital habitats for birds and invertebrates are diminishing due to climate variability and water diversions. The keystone species, Ephydra gracilis, known as brine flies, is central to this ecosystem's food web.Microbialite mounds of haloarchaea, algae, and cyanobacteria sustain E. gracilis, but receding shorelines and record-low lake levels intensify salinity, reducing food sources and brine fly survivability. This decline has far-reaching consequences, as E. gracilis accounts for over 50% of the diet for 10 million migratory birds at GSL.Ongoing research is focused on refining methods for monitoring populations of Ephydra species in response to changing salinity and elevation levels. This research is vital for the preservation of the lake's ecosystem and biodiversity.

Relationship with soul: a short excursion in psychology and religion

March 21, 2024 12:00 AM
Authors: Genna Howard, Cameron John. Mentors: Cameron John. Insitution: Utah Valley University. In the history of psychology, the concept of soul played a significant role informing philosophy and theory. In the late 1800’s many questioned the concept of soul in favor of measurable concepts that aligned with the scientific method, distinguished from religious classification that were deemed unworthy of pursuit. In the emergence of the science method, the concept of soul faded and the field of psychology experienced soul-loss, becoming soul-less. After nearly 150 years, there is a movement in the field advocating for soul to return to its former status by shedding light back onto the soul. For some, soul is aligned with religious thought. Religions are experiencing a loss of congregants, members engaging in faith transitions, and experiencing soul-loss. This paper will compare and contrast what happened in psychology with the experiences of some in religious organizations while looking at how the emotion of fear plays a part in both organizations. The methodology utilizes historical concepts and experiences shared by the brave souls who are challenging the current beliefs in both fields. In addition, anecdotal, informal information provided by individuals close to the authors is used to emphasize the practical application of this crisis in psychology and religions with the goal of reigniting a passion for soul.

The Influence of Political Affiliation on Academic Performance: An Examination on How Familial Political Beliefs May Impact a Child’s Educational Outcomes

March 21, 2024 12:00 AM
Authors: Ellery White. Mentors: Yi Yin. Insitution: Utah Valley University. This study will examine the influence that parental political beliefs may have on students’ academic performance. Decades of research have formed empirical links between social- contextual factors and student academic achievement, and this paper will seek to identify whether parental political values play a role in the academic achievement of their children (Lee and Shute 2010; Yamamoto and Holloway 2010). Parental attitudes, behavior, and stylistic approaches to their child’s rearing and education have been extensively studied for how they impact educational outcomes (Pandey and Thapa 2017). This study fulfills the gap in research on the association between parental political beliefs and children’s academic performance. This adds to the academic discourse on the impact parents can have on their children in an academic setting by answering the following questions: How can the political beliefs of parents impact a students’ way of thinking and therefore ability to perform in school? Does the extremity of the parents’ political beliefs make a difference in the outcome of the child’s academic performance? A survey was distributed to a random sample of UVU students which measured their academic performance and the political beliefs of their parents. The statistical program SPSS will be used to conduct a multiple regression analysis to examine the relationship between the independent variable (parents’ political beliefs) and dependent variable (students’ academic performance) to see if there is an association between the two. I hypothesize that students with parents who have strong political beliefs are more likely to be impacted in their academic performance than students with parents who do not have strong political beliefs. Discovering the impact of parental political belief will open several important avenues of inquiry related to educational outcomes of students.

We Are Not Alone: Examining the Impact of a Tween-Teen Diabetes Day Camp

March 21, 2024 12:00 AM
Authors: Heidi Blaylock, Carter Leuba, Eddie Hill, Christina Aguilar, Carla Cox, Aiden Hill. Mentors: Eddie Hill. Insitution: Weber State University. Type 1 diabetes (T1D) is a chronic disease that influences all health aspects. The self-determination theory (SDT) suggests that three psychological needs of competence, autonomy, and relatedness are necessary for motivation to engage in healthy behaviors. Through medical specialty camps, these needs can be met by educating campers on how to manage T1D and realize they are not alone. The volunteer-based, five-day, inaugural REACH teen/tween camp for youth with T1D was held at WSU. Camp activities were engineered around the three basic needs described by the SDT. These needs were promoted by physical and educational activities, and meeting friends. A pre and post evaluation was given. Two measures were significant with autonomy being the greatest, (M=3.93, SD= .75) to post test (M=4.49, SD= .56), with t(25) = -6.258, p= <.001), effect size r = 1.2 Blood glucose levels were collected through an online platform that allowed staff to monitor campers’ levels. The week's average blood glucose level was 152 mg/dL. This study explored the use of SDT to examine the effectiveness of a diabetes camp for youth and hopefully result in better physical and emotional health thus mitigating the risk of complications.

Mountain Haven - Senior Capstone

March 21, 2024 12:00 AM
Authors: Brandon Rojas. Mentors: Kristen Arnold. Insitution: Weber State University. The Mountain Haven building in Salt Lake City, a mixed-use facility, offers a wide range of services, including housing, childcare, and healthcare. The Single Parent Project, a non-profit organization, is working to provide suitable housing solutions for single parents and their children. The primary challenge is creating a secure, private, and healthy living environment that supports the emotional, financial, and mental growth of single parents and their children. To address this challenge, the Mountain Haven building must be designed to meet the unique needs of single-parent families. This includes providing access to quality childcare, flexible work arrangements, and efficient household management solutions. It is also important to foster a sense of community and neighborliness and to ensure that single parents have access to affordable and safe housing in a safe neighborhood (Johnson, 1986). Additionally, the arrangement of the home should be flexible to accommodate both work and childcare responsibilities. The design of the Mountain Haven building should also consider the latest research on daycare centers, healthcare facilities, and interior design. This includes using materials that are free of harmful substances, creating spaces that promote learning and nurture children's development (Monoko, Mukurunge, Bhila, 2021), and using light and color to create a healing environment for parents and children to reduce stress and strengthen the mood, mind, and body. (Khaleghimoghaddam, 2023) By incorporating these principles into its design, the Mountain Haven building can provide single parents and their children with a safe, supportive, and nurturing environment in which to thrive.

Detection of a DNA Virus in Ornamental Plants at Utah Valley University

March 21, 2024 12:00 AM
Authors: Jaylee Montague, Skylar Belka, Gabe Espinoza, Geoff Zahn, Alma Laney. Mentors: Alma Laney. Insitution: Utah Valley University. In May of 2022, a several unidentified trees on Utah Valley University (UVU) campus property exhibited severe virus-like symptoms including: mosaic patterning; yellowing, curling, deformed leaves; and flaking bark. Due to the presence of unidentified aphids and after a literature search, we began investigating the sample for a +ssRNA virus. Extensive testing and RNA sequencing using the MinION v9.4.1 and the cDNA PCR Barcoding kit revealed that neither a ssRNA nor a dsRNA virus were present in the samples, thus, it was suspected that a DNA virus could be the cause. We utilized Rolling Circle Amplification (RCA) on extracted DNA. Following the RCA, gel electrophoresis revealed a strong amplicon larger than 10 kb, suggesting the presence of a DNA virus. Sequencing of the viral genome from the RCA product using the MinION vs10.4.1 chip showed that the mulberry did contain baculoviruses and large DNA viruses. Unfortunately, though, the MinION did not get results for DNA plant viruses, so we sent samples for RNAseq on the Illumina NovaSeq, with results still pending. This is significant since it is likely that the other symptomatic plants near these trees—including redbud and spirea—were infected with the same virus due to RCA amplification in those samples and the presence of the same potential aphid vector. Mechanical inoculations to several herbaceous hosts were done using infected spirea tissue. Furthermore, to our knowledge this is the first report of a DNA virus infecting spirea and redbud in the United States.

Groundwater and Surface Water Interactions in the Provo River Watershed

March 21, 2024 12:00 AM
Authors: Feyan Hoffman, Roshan Abraham, Christine Fowles, Abi Conger, Scott Jenson. Mentors: Daren Nelson. Insitution: Utah Valley University. One of the least understood part of our local water budget is the interaction of groundwater into our lakes and streams. Groundwater models completed by the United States Geological Survey in 2005 for the Utah Lake Watershed suggest zones where groundwater interactions should be either discharging or recharging into our local streams, wetlands, and other water bodies. However, more recent data has suggested that many of these water interaction maps created by the model are inaccurate, and we need a better understanding of how groundwater interacts with these water bodies. Using a water budget analysis, groundwater and surface water interactions are measured by collecting discharge measurements using flow meters at different cross sections along the Provo River and its tributaries. A gaining or losing stream may swap depending on seasonal changes, such as a particular water year being dry or wet–a stream that is typically gaining may be recharging the aquifer during a dry year. The USGS model is a good basic representation of interactions between groundwater and surface water. Our data suggests that due to highly variable water levels of Utah Lake and local groundwater levels, some discharge and recharge zones in the Provo River subbasin are likely to change over time. In addition, some sections of the river may be perched and not interact with the groundwater system at all. In order for us to better manage these important resources, further analysis of flow behaviors in the Provo River and its tributaries need to be completed. This study is part of a larger study that includes adding two new permanent flow gauging stations to provide a long term record that will enable water managers to better decipher why the groundwater and surface interactions are not fitting the USGS model.

The Ethnobotanical link between Tropane Alkaloids and Datura

March 21, 2024 12:00 AM
Authors: Cole Statham, Katelyn Thomas. Mentors: Michael C Rotter. Insitution: Utah Valley University. Datura (Solanaceae) is a potent hallucinogenic genus of plants that has varied uses across cultures. Tropane alkaloids in these plants are potent compounds that, depending on dosage, can offer the user a psychoactive experience or cause severe reactions including death. For some, Datura is little more than an ornamental flower or an ideal source to have a psychedelic experience. While for others it is a sacred plant, used on special occasions, and only permitted to be handled by those who have been prepared and trained to do so. An explanation for these cultural differences could be that cultures with taboos surrounding this plant are likely those that have species of Datura with variable levels of tropane alkaloids, while cultures without taboos are likely to have species with consistent levels of tropane alkaloids. Here we focus on six species of Datura using literature reports of tropane alkaloid contents and compare the variability in these phytochemicals to cultural uses of these plants. We predict that societies with cultural taboos will be more likely to be those with species that have higher variability in tropane alkaloids.

Mechanical to Electrical Energy Conversion of a Door Swing

March 21, 2024 12:00 AM
Authors: Spencer Brown, Shawn Pepper, Carson Draughon, Ulises Thornock, Dustin Shipp. Mentors: Dustin Shipp. Insitution: Utah Valley University. In the shadow of the 2021-2023 global energy crisis, the need for alternative sources of energy has reached an all time high. To combat this, we have developed a prototype method of harvesting kinetic energy from a door swing, converting that energy into electricity, and storing it inside a battery for future use. Our experiments have demonstrated the capability to use the energy from one door to charge a cellular phone, but we believe this method could be applied on a much larger scale. In this poster we will discuss the method, design, and measurements from our device, as well as possible future applications.

Mayfly Wing Wonders: Uncovering Genetic Threads in Parthenogenic Individuals using RNA

March 21, 2024 12:00 AM
Authors: Melissa Rangel, Avery Larsen, Heath Ogden. Mentors: Heath Ogden. Insitution: Utah Valley University. Mayflies, also known as ephemeroptera, are members of the first group of insects that evolved the ability to fly(Gillott, 2005). Distinct developmental characteristics of the life stages of the mayfly are the reason that Ephemeroptera are of particular interest.The aquatic nymph stages do not have wings, but they do possess abdominal leaf-shaped gills, and in some cases gills associated to the legs. The abdominal gills can sometimes be used to help propel the insect through its environment (Eastham, 1936) in addition to performing gas exchange. Centroptilum triangulifer (family Baetidae), will be used for RNA extractions to study the developmental genetic profiles for characteristics such as wings and gills. Objectives for this research are 1). Acquire samples from different instars, subimago, and imago. 2) Perform 10 RNA extractions. 3) Use Qubit technology to ensure ≥ 20 ng/μL RNA concentration per ≥ 10 μL. 4) samples will be packaged in thermo-stable shipping boxes and sent to Novogene where samples are tested once more for quality control. 5) Once quality is confirmed, samples will be sent and processed by Novogene. 6). Using an in-house bioinformatics workflow, RNA data will be checked for quality, trimmed, aligned, and assembled. The assembled contains will be used to search for genes of interest. 7) the resulting RNA expression profiles will be compared across the installs, sub imago, and imago and to other expression profiles from other related insects.

Pubertal Development and Estrous Cycling in POMC-deficient Mice

March 21, 2024 12:00 AM
Authors: Jacob Prescott. Mentors: Zoe Thompson. Insitution: Utah Valley University. The pro-opiomelanocortin (Pomc) gene encodes POMC, which is differentially processed to produce adrenocorticotropic hormone (ACTH), beta-endorphin, and three melanocyte-stimulating hormones, among other peptides. POMC neurons are principally located in the arcuate nucleus (Arc) of the hypothalamus, where they are essential in the control of food intake, energy expenditure and body weight. Several different mutations in the POMC gene have been shown to cause early-onset obesity and adrenal cortical insufficiency in humans. We are working with a mouse model with a hypothalamic-specific POMC deficiency. These mice exhibit hyperphagia, early-onset obesity, and also seem to be infertile. We are interested in examining potential differences in pubertal development, as well as reproductive function. Specifically, we will examine day of vaginal opening, day of first estrus, and estrus cycling in juvenile female POMC-deficient mice. The estrus cycle has four stages: proestrus, estrus, metestrus and diestrus. Although hormone levels in the blood differ during the four stages, these are difficult and expensive to measure. A less invasive measurement is to take vaginal cell samples each day and examine them under the microscope. Three different types of cells are present in different ratios depending on the stage of the cycle: nucleated epithelial cells, leukocytes, and cornified epithelial cells. We will track estrus cycle changes during pubertal development and after to see if there are differences between wildtype, heterozygous, and homozygous POMC-deficient mice.Learning more about how POMC-deficiency affects reproductive function may help us understand more about the link between obesity and infertility.

Microbiome of PCB Contaminated Sediments

March 21, 2024 12:00 AM
Authors: Jerzee Findlay, Gina Fuller. Mentors: Katrina Twing. Insitution: Weber State University. Polychlorinated Biphenyls (PCBs) are toxic chemicals which were popularly used in electrical manufacturing companies from the 1930s - 1970s and are known to cause significant health concerns for humans even today. These have also been termed “forever chemicals” due to their ability to bind to sediments and soils, which results in difficulties with removal or degradation in contaminated environments. One site of widespread PCB contamination is Pittsfield, Massachusetts, where improper disposal of industrial waste by a General Electric plant has led to chronically contaminated rivers and ponds, even decades later. The aim of this research project is to learn more about the microbial communities that coexist with these toxic forever chemicals, hoping to find evidence that they can degrade PCBs through metabolism. This specific study within the project focuses on microbial diversity of sediment samples collected from the contaminated Woods Pond, located downstream of the Pittsfield General Electric plant.: We performed DNA extractions, PCR amplification, and 16S rRNA amplicon sequencing on an Oxford Nanopore MinION DNA Sequencer. Preliminary data suggest that the samples contain genera known to be associated with PCB degradation, such as Paenibacillus, Clostridium, Rhizobium, and Sphingobacteria. With this understanding, future efforts aim to evaluate the ability of these environmental bacteria to degrade PCBs.

MRSA induced biofilm clearance by bacteriophage and antibiotic.

March 21, 2024 12:00 AM
Authors: Rainey Hughes, Avalon Marker, Elizabeth Bouwhuis, Yeshaswini Dudde, Bryan Dopp, Scot Carington, Jared Nelson. Mentors: Daniel Clark. Insitution: Weber State University. Antibiotic resistance is a pressing concern within the medical community as bacteria's resistance to antibiotics is escalating alongside the increased usage of antibiotics. According to the CDC, there are close to 2.8 million antibiotic resistant infections every year, with about 35,000 of them resulting in death. This issue has prompted antibiotic stewardship programs in clinics and hospitals to avoid adding to the list of resistant bacteria. Staphylococcus aureus, including the formidable methicillin-resistant S. aureus (MRSA) strain, poses a grave threat due to its antibiotic resistance. The challenges stemming from this resistance become even more formidable when these infecting bacteria assemble into biofilms. Biofilms are robust, adhesive layers composed of bacteria and their extracellular matrices of polysaccharides, proteins, and DNA. In clinical environments like hospitals, biofilms frequently develop on medical devices such as stents, catheters, and IV lines, as well as on metal and plastic surfaces of medical equipment. These biofilms exacerbate antibiotic treatments due to incomplete eradication; the most resilient bacteria persist after exposure. There is evidence indicating that bacteriophages, which are viruses that will a target particular species or strain of bacteria, have the ability to encode depolymerases. These depolymerases can identify biofilms, adhere to them, and subsequently break down extracellular polymeric substances. Furthermore, bacteriophages can produce lysins, which induce bacterial cell death through cellular lysis. These characteristics can potentially render the bacteria more susceptible to antibiotics. The use of bacteriophages can also be beneficial when it comes to the concern of opportunistic infections. Due to its selectivity to specific bacteria, it can attack the target hosts and leave the natural flora intact.In our research, we have induced biofilms in our bioreactor. With these biofilms we have been able to test different concentrations of multiple antibiotics, including Vancomycin, Oxacillin, and Carbenicillin in combination with phage K at different concentrations. Our research is aimed at showing a synergistic relationship between phage K and antibiotics, that will allow a subinhibitory concentration of both, in combination, to induce a complete kill and clearance. We have measured this by evaluating bacterial growth via absorbance measurements at 600nm in a Tecan plate reader. We have also measured biofilm clearance using the plate reader and measuring fluorescence at 630nm with a biofilm tablet assay. It was found that a subinhibitory concentration of antibiotic alone did not induce a complete kill and clearing, and that a subinhibitory concentration of phage alone did not induce a complete kill and clearing. However, once these concentrations were used in combination with each other, the complete clearing and killing of MRSA was achieved, and furthermore, was achieved with the antibiotic that the staphylococcus aureus is resistant to. Leading us to believe that we have found a renewed use for a currently ineffective defense mechanism.

Transdermal antiseptic products as a method to decrease skin bioburden prior to surgery

March 21, 2024 12:00 AM
Authors: Kiersten Gardner, Hannah Duffy, Abbey Blair, Nicholas Ashton, Porter Stulce, Dustin Williams. Mentors: Dustin Williams. Insitution: University of Utah. Transdermal antiseptic products as a method to decrease skin bioburden prior to surgeryKiersten Gardner(1,2), Hannah Duffy(1,2), Abbey Blair(2), Nicholas Ashton(2), Porter Stulce1(2), Dustin Williams(1,2,3,4)1 Department of Biomedical Engineering, University of Utah, Salt Lake City, UT2 Department of Orthopaedics, University of Utah, Salt Lake City, UT3 Department of Pathology, University of Utah, Salt Lake City, UT4 Department of Physical Medicine and Rehabilitation, Uniformed Services University, Bethesda MDIntroduction: Preoperative skin preparation (PSP) kits are used before surgery to prevent surgical site infection (SSI). These kits consist of alternating scrubs of alcohol and Chlorohexidine Gluconate (CHG) or Povidone Iodine (PVP-I). Transdermal antiseptic products like Ioban, Tegaderm, and Surgiclear are also used clinically to eradicate skin bacteria by releasing antiseptic over time. Despite these precautions, infections often occur, usually stemming from a patient’s endogenous skin flora. The bacteria causing SSI reside deep in dermal sweat glands and hair follicles, untouched by traditional PSP. To eliminate these bacteria, antiseptics must diffuse deeper into the skin at concentrations above the minimum inhibitory concentration (MIC). We screened FDA-approved topical antiseptic products using a modified Kirby Bauer Assay to assess bacterial kill over time. We hypothesized that extended use of topical antiseptic products prior to surgery would kill deep-dwelling skin bacteria. We tested the extended use of these products on pig backs in conjunction with a CHG PSP to evaluate remaining bioburden. Methods:We determined the minimum inhibitory concentrations (MIC) for CHG and PVP-I against three common skin bacterial strains. We then took 6 mm biopsy punches of Tegaderm, Surgiclear, and Ioban and placed them on fresh bacterial lawns daily for 3 days. We measured the zones of inhibition (ZOI). Lastly, we applied the products to the backs of 4 Yorkshire pigs (n=4 products per test). After 48 h, we removed the products, performed a PSP- CHG scrub, and excised skin sections underneath the products. We homogenized the skin and quantified colony forming units (CFU)/g tissue. We analyzed the outcomes statistically using a mixed effects linear regression to determine significance.Results:The average MIC values for CHG and PVP-I were 2 and 2,000 ug/mL for Staphylococcus aureus, respectively. The average 24 h ZOIs for S. aureus were 7.9, 22.4, and 10.1 mm for Ioban, Tegaderm, and Surgiclear, respectively. The average log10 reduction for the CHG PSP, Ioban, Tegaderm, and Sugiclear were 1.87 ± 0.232, 1.65 ± 0.192, 1.69 ± 0.222, and 1.77 ± 0.316 CFU/cm2, respectively. The p values between the CHG PSP and Ioban, Tegarderm, and Surgiclear were 0.491, 0.572, and 0.746, respectively. Discussion:The benchtop data indicated adequate antiseptic diffusion and kill. In the porcine model, however; the presence of any of the products resulted in a statistically insignificant log reduction. Extended use of FDA-approved transdermal antiseptic products does not appear to decrease the skin’s bioburden. It appears that the products are not releasing high enough concentrations of the antiseptic to kill bacteria.

Ransomware Resilience and Ethical Dilemmas: A Comprehensive Review of Threat Landscape, Impact, and Mitigation Strategies

March 21, 2024 12:00 AM
Authors: Asmaa Alsharif. Mentors: Sayeed Sajal. Insitution: Utah Valley University. Ransomware is malicious software which restricts users from accessing their computer and personal data through encryption. Ransomware attacks target a variety of victims including individuals, organizations, businesses, and governments. Attackers take control of this sensitive data and hold it hostage until a ransom is paid. Whether or not ransom is paid, the attackers’ damage can be irreparable. It includes but is not limited to exposing personal information, identity theft, blackmail, permanent deletion or corruption of valuable data, and Distributed Denial-of-service (DDos). Moreover, the financial implications of ransomware attacks are substantial. Victims face not only the direct costs of ransom payments, but also the expenses associated with system restoration and the potential fines for data protection violations. Furthermore, an ethical dilemma emerges from the response to extortion, as victims must grapple with the moral implications of potentially supporting criminal activities by paying ransoms to recover their data. This raises questions about the broader responsibility of stakeholders in cybersecurity and their duty to protect data privacy. The first ransomware attack emerged in 1989 and since then, ransomware attackers have persisted as a cybersecurity threat, striking at the core of data privacy. This paper delves into the multifaceted impact of ransomware incidents on data security, current ransomware techniques and strategies, and the ethical dilemmas they raise.Because ransomware attackers are constantly evolving their methods, it is important to routinely review the current literature to fully understand the tactics and techniques used by these cybercriminals. This research paper will review, analyze, and synthesize the existing literature about ransomware. It is crucial for individuals and organizations to be proactive, understand the nature of the threat, and take precautions to protect themselves and their data. This study encourages further research and discourse on the multifaceted impact of ransomware attacks on data privacy and the pursuit for effective countermeasures.

The Folklore of the Ghastly Menace

March 21, 2024 12:00 AM
Authors: Matilda Gibb. Mentors: Ami Comeford. Insitution: Utah Tech University. Prior to 1930, cannabis was used frequently in therapeutic practices and was found in many over the counter health products. However, around this time what has been dubbed the “pot panic” began infecting American citizens. It was then the film Reefer Madness came onto the scene, exacerbating the public’s trepidation over the allegedly morally degrading effects cannabis inflicted. Putting melodrama at the forefront, the film exploits societal queasiness over sex, drugs, violent crime, and immigration to push its propagandist agenda. The fear mongering rhetoric and imagery used effectively poisoned the public and altered societal perceptions of medical and recreational cannabis use. The goal of this project is to analyze the rhetorical argument presented in the film and address its broader reach and effects. Lastly, I will argue that the message presented in Reefer Madness was not based on any logical argument; it was based on folklore.

Lake Bonneville's Legacy: Unraveling Genetic Drift and Diversity Loss in West Desert Bonneville Cutthroat Trout

March 21, 2024 12:00 AM
Authors: Tanner Van Orden, Dennis Shiozawa, Peter Searle, Ana Kokkonen, Paul Evans. Mentors: Paul Evans. Insitution: Brigham Young University. The Bonneville cutthroat trout (Onchorynchus clarki utah) is the only trout species native to the Northern and Southern Snake ranges in Eastern Nevada. Streams on the east side of both ranges flowed into Lake Bonneville 12,000 – 15,000 years ago when Lake Bonneville was at its maximum. As Lake Bonneville retreated, Bonneville cutthroat trout in these streams were left isolated. To better understand how Bonneville cutthroat trout in the study area are coping with a changing climate, we Investigated the genetic diversity of Bonneville cutthroat in the Northern and Southern Snake ranges and compared them to historic samples. We found highly differentiated cutthroat trout populations in close proximity to each other and a genetic diversity loss of up to 86.3% in the last 12 years.

Ancestral Puebloan Ceramics Technology and Vessel Properties at Alkali Ridge Site 13

March 21, 2024 12:00 AM
Authors: Carolina Corrales. Mentors: James R. Allison. Insitution: Brigham Young University. This research analyzes ceramics found at the Alkali Ridge Site 13 in southeast Utah. The information generated with this research will allow us to know more about the technological choices of the Early Pueblo I people who lived at this location in the late A.D. 700s. The methodology will examine rim sherds through refiring and porosity tests. Refiring small sections of the sherds will provide initial information about the chemical composition of the clay used to create the vessels. The porosity tests should help determine the pieces' physical properties linked to different technologies. The combination of all these data will show differences in raw materials and their impact on the constitution of the vessels. The database obtained will allow us to statistically compare information from red, grey, and white wares, identifying patterns in size, shape, kind of material, and the technology used for each type.

Quantifying Approximation Errors in the Flash Thermal Diffusivity Measurement Technique Using High Fidelity Simulations

March 21, 2024 12:00 AM
Authors: Tage T Burnett, Jakob G Bates, Christopher R Dillon, Matthew R Jones. Mentors: Christopher R Dillon. Insitution: Brigham Young University. In recent years, modeling and simulation have become more prominent in solving heat transfer problems. The accuracy and predictive power of heat transfer simulations is limited by the quality of the thermal properties used within the model. Thus, one method for improving computational accuracy is measuring thermal properties more precisely. Additionally, increased precision of thermal properties benefits other aspects of engineering including design and analysis. This research focuses on quantifying approximation errors in the widely adopted flash method for measuring thermal diffusivity. The flash method leverages several approximations to make it simple and easy to use; however, these approximations do not reflect reality and introduce measurement errors. Understanding these errors is critical for developing high-precision thermal diffusivity measurement techniques.In the flash method, the top surface of a small, cylindrical disc of material is subjected to a short pulse from a laser or flash lamp and the time-dependent temperature at the opposite surface is recorded. The thermal diffusivity is calculated using those temperature measurements in combination with a mathematical model. The accuracy of the flash method depends upon the accuracy of the mathematical model. One common mathematical model is the Parker Model. This model assumes that all of the energy from the pulse is deposited in an infinitesimally thin layer at the surface of the material and negligible heat is lost to the environment. These assumptions simplify the model, making it easy to use, but introduce errors into the measured thermal diffusivity.Computational methods can quantify these inaccuracies. Factors including heat lost to the environment, the temporal profile of the laser pulse, and the spatial distribution of the deposited energy can be incorporated into heat transfer simulations. Higher fidelity mathematical models can also be developed to account for these complexities. This project includes these and other factors to make simulations as realistic as possible. Various mathematical models, such as the Parker Model and higher fidelity models, are then used to calculate the thermal diffusivity from the resulting time-dependent temperature profiles and their measurements are compared to the simulated material’s true thermal diffusivity. Repeating this process for several material types will allow the precision of the models to be analyzed for each case. This analysis will be summarized at the conclusion of this project, providing a framework for developing more precise thermal diffusivity measurement techniques.

More Than Accommodating

March 21, 2024 12:00 AM
Authors: Natalya Misener, John Wolfe. Mentors: John Wolfe. Insitution: Utah Tech University. In our effort to improve education and create a more inclusive learning environment, Natalya Misener and Professor John Wolfe from Utah Tech University are exploring the experiences of neurodivergent students in classrooms. Our goal is to better understand, support, and empower these students, challenging the way things are typically done. We believe it's important to understand that these conditions come in a variety of forms and affect both students and professors in the classrooms in ways that are not currently being discussed, especially as many minorities, especially women and people of color, go undiagnosed and unaccommodated for a variety of reasons. We believe that by educating professors and students alike on how classroom environments can be more supportive of neurodivergent students, we can benefit the entire classroom, including ‘typical’ students. To make this happen, we believe it's important to rethink how we organize our classes, assignments, and interactions, so that we don't have to rely too much on services like the Disability Resource Center (DRC). We have practical suggestions, like adjusting assignments and deadlines and creating a comfortable classroom environment. It's also crucial to be clear in our expectations and listen to what the students need. We ask some important questions, like whether students should consider their instructors' limitations and how students see disabled instructors in their journey to graduation as well. We call for a shift beyond just accommodating neurodivergent students. We want to encourage educators to think about how they can better support all students in their classrooms. It's urgent that we change how we approach neurodivergent students- in order to create a more inclusive, supportive, and successful environment for us all.

Measuring shear wave speed in tendons using low-cost accelerometers on a flexible PCB with an Arduino microcontroller

March 21, 2024 12:00 AM
Authors: Eli F Smith, Christopher Dillon, Matthew S Allen. Mentors: Matt Allen. Insitution: Brigham Young University. Background: Shear wave tensiometry offers a method to measure in vivo tendon tension, crucial for inferring applied loads on tendons. However, existing equipment for this purpose is costly and lacks mobility, limiting the ability to study a larger cohort of subjects engaged in various physical activities. Goal: This research aimed to assess the viability of utilizing low-cost digital accelerometers in conjunction with an Arduino-based microcontroller for shear wave tensiometry. Approach: This work employs surface-mounted accelerometers on a custom flexible printed circuit board (PCB), so that even spacing can be maintained between the accelerometers without interfering in data collection. To test the system and verify its ability to acquire measurements at a high enough rate, the PCB was connected to a shaker driven with a known sinusoidal signal. The flexible PCB was held in place on the Achilles tendon using athletic tape with a tapper placed on the tendon to send a shear wave through the tendon. Results: The results obtained to date compare the accuracy of the proposes system relative to the current system, which uses instrument grade accelerometers. Results obtained to date on the tendon reveal the degree to which the PCB interferes with the measurements, and suggest possible modifications to improve future designs. Conclusion: To attain valid shear wave tensiometry data, further iterations of the flexible PCB design are needed. Moreover, employing more powerful microcontrollers capable of accommodating the requisite sample rates is necessary for an improved system.

Your Tooths Appetite for Hydroxyapatite

March 21, 2024 12:00 AM
Authors: Megan Wesenberg, Britain Jeppesen, Brianna McDaniel. Mentors: Jodie Lopez. Insitution: Utah Valley University. Abstract: Hydroxyapatite is a natural substance found in bones and the enamel of teeth. When hydroxyapatite is compromised, demineralization begins to occur which can eventually lead to cavities. There are many fluorides on the dental market, some having negative connotations associated with them. Hydroxyapatite products have been explored as an alternative for traditional fluorides to create similar effects without the potential for toxicity. Fluorosis is the main toxicity point addressed. Many patients are apprehensive of the use of fluorides due to possible overconsumption and uncontrolled levels within the local water supply. Because Hydroxyapatite is very biocompatible, access to it does not pose any toxic concerns. Using this alternate material allows these patients access to similar benefits in the oral cavity that fluoride would provide them while also being considerate of their personal beliefs and concerns. Caries are an extremely prevalent issue within the dental office, accounting for pain in patients and a majority of treatment done daily. Caries are very prevalent in the adult population. Hydroxyapatite is a useful substance in caries prevention, another similarity that it has in common with fluorides. Remineralization of these early carious lesions through the aid of hydroxyapatite leads to avoidance of more invasive treatment at a later date. A common use for fluoride is limiting sensitivity of teeth that can be felt from a variety of different stimulants within the oral cavity. Hydroxyapatite can also be used as a desensitizing agent. Hydroxyapatite enters dentin tubules and blocks them, limiting nerve stimulation within the dental pulp.

The Primary and Secondary Metabolites of Tomato as a Response to Herbivory and Simulated Herbivory

March 21, 2024 12:00 AM
Authors: Iris Cepeda, Tabitha Weir, Jonathan Cook, Honey Ordonez. Mentors: Olga Kopp. Insitution: Utah Valley University. Solanum lycopersicum (tomatoes), are beloved herbaceous crops well known for their red bearing fruits. They are best grown in well-draining soils with access to full sun and are endemic to South America but grow all across the world where the conditions allow. Tomato fruits provide a quality source of phytochemicals and antioxidants such as lycopene, vitamin C, beta-carotene, and phenolic compounds which can substantially improve one’s healthy diet. S. lycopersicum are members of the nightshade family, which are known for their production of often toxic glycoalkaloids. The presence of these compounds usually deters herbivores by increasing their concentration as a defense response. There are, however, herbivores like Manduca sexta (tobacco hornworms) that feed on members of the nightshade family by dealkylating these glycoalkaloids. It is hypothesized that plants have the ability to modulate their defensive response based on queues from the environment and from their herbivore pests. Our research objective is to determine whether a S. lycopersicum plant undergoing defoliation from M. sexta will have the same molecular response as a plant undergoing simulated herbivory. Four treatment groups will be used with each treatment group having 8 replicates. Before treatment begins, the groups will be isolated by a non-permeable surface so air-borne defense signals from one group do not elicit a response in another. In the herbivory treatment group, M. sexta will be allowed to feed for a 24-hour period to account for diurnal and nocturnal herbivory, as well as high plant enzymatic response. Damage treatment 1 will simulate herbivory using a hole-punch, avoiding the midvein. Damage treatment 2 will simulate herbivory using a single transverse cut across the leaf blade and midvein. The undamaged control will have no herbaceous or mechanical damage done. After the treatment period, half of the leaf matter from all groups will be collected and frozen in liquid nitrogen to preserve all metabolic processes and GCMS will be used to analysis metabolite differences. The other half of the leaf matter will be analyzed using UV-spectrophotometer analysis with bromocresol green to compare the glycoalkaloid expression between the treatments. It’s expected that there will be a reduced expression of the defense glycoalkaloids in the herbivory group of S. lycopersium when compared to the two defoliation groups. While the three treatments could respond similarly to their treatments by primary metabolite expression, the type of defoliation could have a greater effect on this than the herbivory group.

Safety and Fairness in the Courtroom

March 21, 2024 12:00 AM
Authors: Ella Johnson, Aubria Soto, Andrew Bodily. Mentors: Chelsea Romney. Insitution: Brigham Young University. This study investigated the relationship between a sense of safety and a sense of fairness in the courtroom. In the Provo City Justice Court, court customers were offered an optional survey that covered questions about their experience in the courtroom. A section determining an individual’s ability to access the court and a section to see how fairly they felt they were treated were compared. The results reveal a significant positive association between a sense of safety and perceived fairness, indicating that when individuals felt safe in the courtroom they also tended to believe that their trial was conducted fairly (Pearson Correlation = 0.527). It was also found that for the Provo City Justice Court, most court attendees answered high on the scale for both access (M = 4.5/5) and fairness (M = 4.6/5) with 145 participants surveyed. Limitations include not surveying online court attendees and the potential bias of survey responses from those who felt dismissed during their sessions. The court experience can be improved through the creation of programs or measures that will increase not only the safety of the court customers but also their satisfaction with the perceived fairness of their trials.

The Value of Relationship Education for Youth and Teenagers

March 21, 2024 12:00 AM
Authors: Stefan Jezik. Mentors: Jocelyn Wikle. Insitution: Brigham Young University. Much preexisting relationship education is focused on adults and those already in romantic relationships. Due to the audience of this relationship education, it is often tailored to fit those experiencing relationship issues in their marriages or with their romantic partner. This form of relationship education frequently fulfills the role of a bandage to a wound, instead of fulfilling a preemptive role that could mitigate the number and severity of relationship problems from developing in the first place. While relationship education can be beneficial for any target audience, research has increasingly turned to this preemptive type of relationship education by recommending that institutionalized relationship education at the highschool level tailor its curricula to youth, teenagers, and emerging adults (Hawkins, 2017; Barber & Eccles, 2003).

Feelings about Modesty and the Prevalence of Eating Disorders in Latter-Day Saint Men and Women

March 21, 2024 12:00 AM
Authors: Kate Binford, Marissa Roper, Brynn Eyre. Mentors: Sarah Coyne. Insitution: Brigham Young University. The purpose of this study is to examine the relationship between personal feelings about modesty and the prevalence of eating disorders (EDs) among Latter-day Saint (LDS) men and women. Participants were recruited through social media and announcements on LDS-specific social media pages. The study has a final sample of n=1,271, 431 of which (33%) had an ED. There is a significant positive correlation between feelings of shame about modesty and the prevalence of EDs (r=0.11, p<.001). This means that, in general, more feelings of shame about modesty are related to a higher prevalence of EDs. Implications of these findings indicate that it may be helpful to reduce any shame-based teachings around modesty in order to protect against EDs.

Does talking about Suicidality help all populations? The data points to Yes

March 21, 2024 12:00 AM
Authors: Elizabeth Smith, Melissa Chavez. Mentors: Jared Neilsen. Insitution: Brigham Young University. Suicidality is a growing public health issue, especially in a neurodiverse population. Suicidality rates are higher among a sample of people with ASD (Demirkaya et al., 2016). While the full causes of why people with ASD tend to be more suicidal are unknown, there are people who are trying to address this with different treatments. Some of the treatments that are being used work in neurotypical people. However, there is a lack of treatment use for those of nuerodiverse populations. One of the areas that we know decreases suicidality is talking about it more, which is contrary to the prevalent myth that talking about suicidality increases rates of suicidal tendencies (Dazzi et al. 2014). Knowing that suicidal tendencies are decreased by talking about suicide, we set out to answer the question: Is the same true for neurodiverse populations who are at more risk for suicide? We recruited a total of 72 participatns, 27 from the ASD community, 20 with social anxiety, and 25 neurotypical people (to act as a control group). To answer this question, we sent out nightly surveys that included questions about suicidality as well as having them come in every 6 weeks to administer the Columbia Suicide Severity Rating scale. For the participant’s first visit, we administered the lifetime version, and then at every other visit, we administered the 6 week version. We then compiled the scores and ran them through R. We found that the scores decreased (i.e. participants were less suicidal) across the visits. This indicates that suicidality is lessened through talking about suicide for neurodiverse populations. Further research is needed to confirm this. While the findings from this study are positive, they need to be considered in the light of several limitations such as attrition from the participants and the recency bias on the part of the students.

The Physiological Effects of Capitalization in Ambivalent Marriages

March 21, 2024 12:00 AM
Authors: Abigail Williams, Kelsie Minga, Abby Baker, Ella Sieg, Olivia Harris. Mentors: Wendy Birmingham. Insitution: Brigham Young University. Background: Research has found positive health benefits in the communication of positive events (capitalization) with others who respond with curiosity and enthusiasm. An expectation is that one’s spouse would respond in such a way. And indeed, if one has a highly supportive spouse this is likely the case. However, not all individuals have a highly supportive spouse and may have a spouse whose behavior is more ambivalent. Such ambivalent, or unpredictable behavior may lead to worse physiological outcomes when sharing good news including increased risk for cardiovascular events. Blood pressure should dip 10-15% overnight (“dipping”). A less than 10% dip is associated with higher cardiovascular disease risk. We looked at capitalization and dipping in ambivalent and supportive couples. Interpersonal Theory asserts that positive or negative behaviors from one spouse can elicit similar responses from the other spouse. Thus we looked at capitalization and dipping for spousal ambivalent behavior, and one’s own ambivalent behavior. Ambivalent behavior, whether one own’s or one’s spouse’s can also impact the quality of the relationship.  Methods: 90 couples were recruited from a local university, social media, and the community. Participants completed measures of marital quality. They were fitted with an ambulatory blood pressure monitor for 24 hours. The monitor took a reading every 30 minutes during the daytime and once an hour overnight. Participants completed a daily diary entry each time the monitor took a reading during the daytime which included questions regarding their present activities (e.g., posture, current emotions, food consumption). Participants returned the equipment the following morning and were compensated.  Results:  Ambivalent behavior was associated with worse relationship quality measured as responsiveness, both in terms of one’s own behavior, and one’s spouse’s behavior. We found no association for systolic blood pressure (SBP) dipping for individuals whose spouse’s behavior was viewed as ambivalent, however diastolic blood (DBP) dipping was in the opposite direction showing ambivalent spousal behavior was associated with healthier dipping. Of interest, when one reported their own behavior as ambivalent when their spouse was sharing good news, their SBP dipping was unhealthy.   Conclusions: Spousal ambivalent behavior seems to be less important than one’s own behavior on SBP dipping. This may be because one is generally aware of their own behavior and understands that such behavior is problematic for the relationship. This awareness, however,  may come with a cost for their health as well as their relationship.

The Impacts of Distress and Perceived Social Support on Heart Rate Variability

March 21, 2024 12:00 AM
Authors: Mikel Cressman, Jackie Richey, Dantzel Petersen Hancey, Bianka Geraldo, Kayden Barlow, Ainsley Lumsden, Olivia Hubble. Mentors: Patrick Steffen. Insitution: Brigham Young University. Heart rate variability or HRV is a measure of the amount of time between a person’s heartbeats and is related to their physiological response to stress. Social support is an important component of positive health outcomes and plays a part in mediating distress. More research is needed to better understand the connection between HRV, social support and distress. We hypothesize that those with low baseline HRV will have higher distress scores and lower social support than those with high baseline HRV. We also hypothesized that someone with high distress and high social support will have higher HRV than those with high distress and low social support. In this study, social support was measured using the Multidimensional Scale of Perceived Social Support (MSPSS), distress was measured using the Counseling Center Assessment of Psychological Symptoms (CCAPS), and baseline HRV was measured using a NEXUS biofeedback device using ECG leads on the collarbones and left rib. Our sample consisted of 236 college students (17-28 years old; 57.6% female; 85.9% white) drawn from an online recruiting software and student development classes. For the first hypothesis, we will use a MANOVA to compare both low and high HRV baseline with mean MSPSS and CCAPS scores. We will use an ANOVA to compare differences in HRV between those with high MSPSS and high CCAPS scores to those with low MSPSS and high CCAPS for the second hypothesis. We expect to find that those in the lower HRV group will have higher CCAPS scores and lower MSPSS scores when compared to the high HRV group. We also expect to find that participants in the high CCAPS and high MSPSS group will have a higher HRV when compared to the high CCAPS and low MSPSS group.

The Effects of Anterograde Amnesia on Mnemonic Discrimination: A Single-Subject Case Study

March 21, 2024 12:00 AM
Authors: Sara Knowlton, Sam Chipman, Samantha Stabler, Alex Osmond, Brock Kirwan. Mentors: Brock Kirwan. Insitution: Brigham Young University. The hippocampus is a brain structure involved in recognition memory and pattern separation, or the ability to disambiguate potentially interfering or overlapping memory representations. The Mnemonic Similarity Task (MST) has been used to assess memory specificity by asking participants to encode a series of objects and later perform a recognition memory test with repeated items (targets), similar but not exact repeats (lures), and novel items (foils). In a single-subject case study, we utilized the MST in evaluating recognition memory over various delays of a subject with anterograde amnesia. Subject MC is a healthy young adult female who underwent a unilateral amygdalohippocampectomy as a treatment for epilepsy. This procedure included the complete removal of her hippocampus in the right hemisphere, which we verified with magnetic resonance imaging. In addition to the MST, we compiled a battery of neuropsychological tests, including the Wide Range Assessment of Memory and Learning (WRAML-3), the Delis-Kaplan Executive Functioning System, and the Wechsler Abbreviated Scale of Intelligence (WASI-II) to more holistically assess MC’s memory deficits. Preliminary analyses showed significantly lower lure discrimination when compared with control subjects, indicating deficits in pattern separation. Further analysis of MC’s MST results are being conducted to evaluate her broader ability for recognition memory.

How Depression Affects “Feeling the Spirit” in College Age Latter-Day Saints

March 21, 2024 12:00 AM
Authors: Nadia Mando, Josh Shaeffer, Jared Nielsen. Mentors: Jared Nielsen. Insitution: Brigham Young University. Background: “Feeling the Spirit” is an important experience for many active Latter-Day Saints. Feeling the Spirit is often defined by the presence of positive, even if minor, feelings which are perceived to be interactions with deity. However, some Latter-Day Saints struggle to feel the Spirit which can be distressing to them. Recently, LDS leaders have focused on understanding how depressed individuals might experience “feeling the Spirit” differently.Objective: Our pilot study sought to understand the relationship between depression and the frequency and strength of spiritual experiences.Methods: We used the Depression Anxiety Stress Scale-21 (DASS21) to measure depression. We created two separate measures to inquire how frequently and strongly participants felt the Spirit in the last six months. We also created a task asking participants to read multiple scripture passages and report how strongly they felt the Spirit while reading each passage. Responses to each passage were averaged to create a state measure of feeling the Spirit. We hypothesized that higher scores of depression would predict lower scores on feeling the Spirit for all three measures.Results: We found that scores on depression (M=11.388, SD=7.844) significantly correlated to frequency (M=3.683, SD=0.760, r= -0.352, p<.001) and strength (M=4.004,SD=0.628, r=-0.453, p<.001) of the Spirit. However, depression scores were not significantly correlated with our state measure (M=2.384, SD=0.903, r=-0.192, p=0.078). In our regression models we found that depression is a significant predictor of both frequency (R2= 0.091, F(1,83)=8.347, p=.005, =-0.029, p=.005) and strength (R2=0.158, F(1,83)=15.523, p<.001, = -0.032) of feeling the Spirit but, not of feeling the Spirit during the scripture task (R2=0.003, F(1,83)=0.236, p=0.628, = -0.463).Conclusion: These findings suggest that depression may affect how LDS persons experience their relationship with God. Our findings take a step toward explaining why some individuals may experience difficulty in “feeling the Spirit”. Future studies are necessary to elucidate these preliminary findings.

Counting Crowds: An Analysis of Population 'Top-Outs' in Counties Across the United States

March 21, 2024 12:00 AM
Authors: Maisie Baird, Hugh Kerry, Samuel Otterstrom. Mentors: Samuel Otterstrom. Insitution: Brigham Young University. Throughout the history of the United States, populations have experienced continual fluctuations across its diverse landscape. Although much research has focused on the growth and decline of cities and counties, many of these studies have focused on the positive population growth in larger cities and counties, insomuch that scholars and the public might have an incomplete or skewed view of the historical population geography of the country. However, this paper presents a broader perspective, including times of both population growth and decrease across regions and multiple decades and showing how these trends do not follow strictly positive trajectories nor exhibit isolated randomness. This paper will focus on specific examples of counties across the United States, highlighting why there were population ‘top-outs’ in these areas. For example, Sheridan County, Nebraska experienced a population boom at the onset of World War I, as it became the United States’ primary source of potash. However, at the end of World War I, potash could again be cheaply imported from Europe so, Sheridan County lost its booming industry, resulting in population decline. This research delves into the concept of population ‘topping out’ in counties, emphasizing a comprehensive understanding achieved through a holistic framework that accounts for geographic, regional, economic, and temporal aspects.

Contrasting Representations of the Berlin Wall in American and German Museums

March 21, 2024 12:00 AM
Authors: Breanne Herrmann. Mentors: Paul Stavast. Insitution: Brigham Young University. The construction and preservation of the Berlin Wall in 20th century Germany has perpetuated a social legacy perceived differently in various countries. Although the historical facts are unchangeable, their representation by institutions in each country varies and reveals their unique participation with the German Democratic Republic. This paper analyzes the portrayal of the Berlin Wall and surrounding GDR events in museums in both Berlin, Germany and American cities. Die Mauer, The Wall museum at Leipziger Platz in Berlin serves as a model of the German perspective. Its focus on the logistics of the Berlin Wall and the social impact in Germany and surrounding satellite countries is compared to the portrayal in American museums, which assume a more general approach of the Berlin Wall as a symbol of greater political struggles. This includes a consideration of locations of museums in America as well as information presented in the exhibits. Identifying differences between museums in these two countries provides insight into the experience of each during the GDR period and subsequent social perceptions of the Berlin Wall's history.
