BACKGROUND: General knee pain is a common complaint among both athletes and older adults. Osteoarthritis is a common etiology for knee pain that can interfere with function during aging and can be assessed by validated questionnaires. It remains unclear whether there exists a dose–response relationship between cartilage loss and pain worsening. Articular cartilage thickness of the femoral condyles can be measured by ultrasound imaging and few studies utilizing this form of measurement exist. It is currently unknown if articular cartilage thickness measured ultrasonographically correlates with pain related ratings in aging athletes. PURPOSE: The aim of this study was to assess whether articular cartilage thickness at the femoral condyles as measured by ultrasound imaging has any relationship to knee pain as rated by the modified KOOS (Knee Injury and Osteoarthritis Outcome Score) survey in senior athletes over the age of 50.METHODS: Data was collected from 35 volunteers (participants in the Huntsman World Senior Games) in St. George, Utah, 2023. All subjects (22 females: mean age = 64.9 ± 6.6 yrs, Ht = 158.7 ± 35.6 cm, Wt= 66.3 ± 10.0 kg; 13 males: mean age = 67.3 ± 8.3 yrs, Ht = 179.3 ± 10.7 cm, Wt= 84.3 ± 13.4 kg) signed an approved consent and completed a modified KOOS survey before being seated on a table, with their back flattened against the wall directly behind them. They were then asked to bring either knee as deeply into flexion against their torso as possible; approximating 120°-140° of knee flexion, depending on the range of motion the subject was capable of. In flexion, the patella was shifted inferiorly enough to expose the femoral condyles so that a short axis image of the articular cartilage was obtained and the thickness of the cartilage was assessed at 3 points.ANALYSIS: All data were analyzed using JMP ver16.2 with a Pearson product pairwise correlations to determine if a relationship between average cartilage thickness correlates with pain subscale scoring from the KOOS in males and females. Correlation between age and thickness was also examined.RESULTS AND CONCLUSION: There were no significant correlations between the pain subscale score and cartilage thickness in males (p=.6998, r=0.1316), females (p=.8733, r=0.0392), or combined (p=.7308, r=0.0655) in this group of senior athletes. Age and thickness was not significantly correlated (p=.1232, r= -0.2877), but did show a trend of decreasing cartilage thickness with age. The addition of more subjects should show age and thickness to be negatively correlated with each other.

This paper will focus on the microbiota’s effects on fruit fly dietary preference for yeast (DPY), to determine if specific nutritional molecules produced by the microbiota control DPY. Previous studies have unsuccessfully sought to identify such small molecules by testing for roles of essential amino acids (Leitao-Goncalves 2017). A study completed in our lab suggested that bacterial thiamine biosynthesis/metabolism genes influence fly DPY because mutations shifted the preference from a diet with less yeast to a diet with more yeast (Call 2022). In our first efforts we found that raising flies on thiamine supplemented diet influenced their DPY. I want to determine if supplementing thiamine specifically causes this shift, and if the shift observed in the mutants is seen due to a lack of dietary thiamine. Here, I will perform the same tests with flies given diet supplemented with other B vitamins to test specificity. I will then confirm the role of bacterial thiamine on these phenotypes by rearing flies colonized with bacterial thiamine biosynthesis/metabolism mutants on thiamine supplemented diets. If these flies raised with increased dietary thiamine prefer a diet with less yeast, and the experiment with other B vitamins does not show a similar shift as thiamine, then the specificity of thiamine as the small molecule involved in yeast preference is confirmed.

Diabetes is characterized by a loss in beta cell function within the pancreas and the subsequent inability to produce sufficient insulin to regulate blood glucose. While current diabetes treatments focus on delivering pharmaceutical insulin to diabetic individuals, such treatments are temporary solutions and do not address the root of the issue. Instead, our research focuses on potential mechanisms for inducing greater insulin secretion within the pancreas of the individual. NK6 Homeobox 1 (Nkx6.1) is a major transcription factor in beta cells and its overexpression in beta cells is associated with higher insulin secretion. We have shown that Syntaxin 1A (Stx1A) interacts with Nkx6.1; Stx1A is of particular interest due to its role in mediating insulin granule fusion at the beta cell plasma membrane, directly impacting insulin secretion. We hypothesize that the interaction between Nkx6.1 and Stx1A may play an important yet understudied role in insulin secretion. Here, we present the results of Stx1A overexpression on glucose-stimulated insulin secretion within pancreatic beta cells, as well as the effect on the Nkx6.1 interaction. Understanding more about the role of Stx1A in beta cells could provide therapeutic targets to induce greater insulin secretion, which could aid in the effort toward finding a cure to diabetes.

Introduction: Breast cancer is one of the most prevalent types of cancer present in society today, and is the second leading cause of cancer death for women. Approximately 13% (1 in 8) of women will develop invasive breast cancer, with 3% of women (1 in 39) dying from this type of cancer. Three important classifications used when formulating a treatment plan for breast cancer are the presence or absence of Estrogen Receptor (ER), Progesterone Receptor (PR), or Hormone Receptor (HR). Treating Estrogen Receptor Positive (ER+) breast cancer with aromatase inhibitors, such as Letrozole, is the current standard treatment for all postmenopausal women. A prior study by Lee et. al. identified PRR11 as the only gene that was significantly overexpressed in resistant vs non-resistant cancers among the 51 genes in chromosome arm 17q23. The goal of the current study is to perform a secondary analysis of this valuable dataset to identify genes, signaling pathways, and biomarkers across the whole human transcriptome that are significantly associated with treatment resistance in ER+ patients.Methods: We retrieved, preprocessed and analyzed 58 ER+ breast cancer samples from patients who had been treated with Letrozole, which are publicly available in the NCBI Gene Expression Omnibus (GEO) database. The Automated Reproducible MOdular Workflow for Preprocessing and Differential Analysis of RNA-seq Data (ARMOR) was used to process our data downloaded from NCBI. This workflow trimmed low quality reads from the RNA-sequence reads, mapped and quantified our data to generate a DEG list. Gene ontology enrichment with camera was also performed. Next, the genes were mapped to common gene identifiers and input to the signaling pathway impact analysis (SPIA) algorithm to identify intracellular signaling pathways that were enhanced by our DEGs. With that information, Pathway2Target was used to identify known drug targets within our identified pathways. Finally, a decision tree-based machine learning approach was used to predict features/expressed genes that could be used to most accurately classify responders vs nonresponders to Letrozole. Results: Our comparison of 36 responders versus 22 non-responders detected a total of 18,735 genes and identified 105 that were statistically significant (p-value < 0.05) after applying a false-discovery rate (FDR) correction, including SOX11, S100A8/S100A8, and IGLV3-25. We then used the Signaling Pathway Impact Analysis (SPIA) algorithm to determine whether any known intracellular signaling pathways were significantly enriched in DEGs (Bonferroni-adjusted p-value < 0.05). This analysis identified 4 pathways that were statistically significant in Non-Responders to Letrozole Treatment. We then used the pathway results to predict 60 existing therapeutic targets that could be repurposed to treat the resistance phenotype. Notably, the predicted targets for the non-response phenotype included VEGFA, a current target for solid tumors as well as ESR1, an Estrogen Receptor. We next wanted to determine whether we could predict transcriptional biomarkers that could aid with identifying patients that do not respond to treatment. To do so, we used the read counts for all samples as the input for this analysis and identified 278 transcriptional biomarkers. Performance metrics for all biomarkers identified yielded an area under the receiver-operator characteristic (AUROC) curve of 0.972 (Figure 2), indicating an exceptional ability to classify Letrozole responders vs non-responders by the transcriptional profile. Sensitivity for all transcriptional biomarkers was measured at 100%, and specificity at 94%. We used the top two biomarkers from our first analysis as input for a second analysis to determine the performance of a smaller subset. Our second analysis determined that PRDX4 and E2F8 together yielded an AUROC of 0.823 and an overall accuracy of 88.2%. Discussion:Our results identify additional DEGs, pathways, targets and biomarkers for further exploration in the treatment and categorization of ER+ breast cancer.

Incidence of diabetes worldwide has grown from 108 million people in 1980 to 422 million people in 2014, nearly tripling in just thirty-four years. Type 2 diabetes (T2D) is characterized by the loss of pancreatic beta cell mass and the failure of the remaining beta cells to provide adequate insulin. Contributing to the development of T2D is glucolipotoxicity (GLT), a condition characterized by the harmful elevation of glucose and fatty acid levels within beta cells. While there are existing treatments for symptoms of diabetes, much remains to be understood about its underlying causes and effective preventative measures. Flavonoids are naturally occurring phenolic compounds found in many fruits and vegetables that have various anti-inflammatory health benefits. Previous studies suggest that epicatechin, a flavonoid present in cocoa, can reduce the effects of diabetes by diminishing insulin desensitization and increasing glucose stimulated insulin secretion (GSIS). Interestingly, the bioavailability of epicatechin is poor, while its metabolites are more easily absorbed in the small intestine. Further studies demonstrated that under non-stressed conditions in beta-cells, hippuric acid, homovanillic acid, and 5-phenylvaleric acid, metabolites of epicatechin, stimulate insulin secretion at concentrations more realistically found in the body. However, the effects of these metabolites in glucolipotoxic conditions are unknown. Here, we present the effects of epicatechin and its metabolites hippuric acid, homovanillic acid, and 5-phenylvaleric acid on beta cell insulin secretion and mitochondrial respiration under GLT culture conditions. This study aimed to contribute to the limited body of knowledge on the bioactivity of flavonoid metabolites on beta cell function under damaging conditions observed with T2D, offering crucial insights for developing effective strategies to harness the health benefits associated with flavonoids.

Authors: Owen Damitz. Mentors: Jeffrey Tessem. Insitution: Brigham Young University. Type one and two diabetes affect the everyday lives of millions of people worldwide. These diseases are characterized by decreased functional beta cell mass. Functional beta cell mass is defined by the beta cell’s ability to proliferate, secrete insulin, and resist apoptosis. Wehave shown that the orphan nuclear receptor Nr4a3 is sufficient to induce beta cell proliferation. We have sought to define compounds that can interact with and modulate Nr4a3 activity. Using AutoDock Vina we have defined a number of compounds that interact with Nr4a3. Here wepresent data demonstrating the ability of these compounds to modulate Nr4a3 mediated proliferation, survival, and insulin secretion in the beta cell. Furthermore, we demonstrate the effect of these compounds to modulate Nr4a3 transcriptional control. These findings are the basis for developing interventions to increase functional beta cell mass as a treatment for type 1 and type 2 diabetes.

Ultrasonic analysis of patellar tendon thickness in active older athletesBACKGROUND: Recent research has suggested that patellar tendon loading through exercise and resistance training can help maintain and increase patellar tendon thickness in older adults. Limited research exists that identifies the average thickness of patellar tendons in younger athletes, however, it is unknown if this thickness remains or is maintained in older adult athletes who have maintained a very active lifestyle.PURPOSE: This study aimed to determine how gender correlates to patellar tendon thickness in the proximal and middle patellar tendon of active older athletes participating in sporting events at the Huntsman World Senior Games.METHODS: Data was collected from 59 volunteers (participants in the Huntsman WorldSenior Games) in St. George, Utah, 2022. All subjects (34 females: mean age = 61.09 ± 7.00 yrs, Ht = 162.41 ± 25.73 cm, Wt= 66.29 ±11.38 kg; 25 males: mean age = 68.68 ± 7.03 yrs, Ht = 178.21 ± 8.63 cm, Wt= 84.42±10.90 kg) signed an approved consent form and then sat on a treatment table with their legs relaxed and dangling off. The probe was placed vertically below the kneecap and an ultrasonic image was taken. Each image showed a small section of the patellar for reference. Each ultrasonic measurement showed the middle and proximal thickness of the patellar tendon. ANALYSIS: All data were analyzed using JMP ver16.2 with a stepwise multiple regression analysis to determine the effect of age, height, wt and gender on patellar tendon thickness. A sex*location mixed model was used to determine differences in middle and proximal thickness between gender. Data were normally distributed, not requiring transformation.RESULTS & CONCLUSIONS: Proximal tendon measurements were thicker than middle tendon measurements on both sides (p=0.0001). There was no significant difference either proximal tendon thickness (p=0.9323) or middle tendon thickness (p= 0.3993) between left and right sides. No significant difference between male and female tendon thickness at either location (p=0.7700). Proximal tendon thickness was greater and this has been found to be greater in younger athletes with a history of patellar tendinopathy. Aging athletes may also have a history of knee pain episodes that could have contributed to this finding. The lack of gender differences in thickness measures was surprising, but may be a result of the level of activity of senior athletes. In the future studies should look to compare active vs non-active aging athletes, more specific age range differences, and how knee replacements and other injuries affect patellar tendon thickness.

Nucleosome positioning, or the placement of nucleosomes along DNA, is known to be a significant factor in determining gene expression in eukaryotic cells. Further, post-translational modifications (or PTMs) help modulate gene expression by acting as an intermediate to other factors. The extent to which PTMs directly affect nucleosome positioning is poorly understood, however. Since gene expression is known to be affected by several coincident PTMs on each histone, the goal of this research is to evaluate the suitability of a Lys-->Gln mutation as a substitute for histone lysine acetylation. If successful, this research can be used to support future combinatorial studies on PTMs and nucleosome positioning without the difficulty of combining several forms of PTMs simultaneously.

Authors: Zach Fiore. Mentors: Jared Nielsen. Insitution: Brigham Young University. Gait apraxia is a type of apraxia that affects lower limb use in walking. It is characterized by difficulty initiating gait, freezing of gait, and other gait disturbances that cannot be attributed to complications affecting sensory, motor, or cerebellar function, psychiatric disease, nor ataxia. Symptoms often present following brain trauma. Previous research has indicated that gait apraxia may be linked to lesions in the frontal lobes, basal ganglia and supplementary motor area. However, the specific cerebral location has been debated with minimal research done on the symptom’s implicated neural circuits. The purpose of this study is to determine the networks in the brain that are involved in the pathophysiology of gait apraxia. To determine this, we used the lesion network mapping method. A systematic literature review was performed, with specific inclusion criteria, to find case studies of patients presenting with gait apraxia stemming from acquired brain injury (n=15). Lesion network mapping analysis (Fox et al., 2018) was performed on 15 cases with a large cohort of healthy control resting-state scans (n=1000). The analysis showed that lesions exhibited functional connectivity to the bilateral medial dorsal and pulvinar nuclei of the thalami (n=15), which supports previous associations of basal ganglia damage contributing to gait apraxia. A novel region, the cingulate cortex (n=15), was also found to be functionally connected to the lesion networks. This region is a part of the cingulo-opercular network, responsible for many functions, including action. This network has recently been found to display strong functional connectivity with the somato-cognitive action network, responsible for coordinating movements with cognitive processes. Further research is necessary to determine the mechanism of how these networks interact in contributing to gait apraxia.

Tight junctions (TJ’s) are composed of mainly three types of cell-adhesion molecules (CAMs) that regulate paracellular permeability in epithelial and endothelial cells. These are claudins (CLDNs), occludin (OCLN), and junctional adhesion molecules (JAMs).There are, however, several (27) isoforms of the claudin molecule, all of which are suspected to have different strengths and other properties in cell adhesion. Currently, the comparative strength of the interactions between different CAMs are unknown and no easily replicable model of a TJ has been created. To address this question we resourced to bacterial expression of these mammalian proteins. MG1655 E. coli cells (with flagellum) were transformed to express claudins 1, 2, 3, 5, and 10 as well as occludin and plated on 0.2% agar plates, allowing them to swim overnight. This allowed for a qualitative spectrum of strengths of the CAMs based on how far the cells were able to spread throughout the plate. Cells that interacted strongly swam less. This technique was applied to the case of the Atlantic Salmon. It swims both in fresh and ocean water. As it transitions, the TJs in its skin changes its composition of claudins. We were able to determine that the set of claudins employed during ocean water swimming are capable of stronger strength. This is consistent with the changes in osmolarity dictated by the amount of solute in the ocean water.

We know that evolution acceptance is low in the United States, and a perceived conflict between evolution and religion is a big predictor of whether someone accepts or rejects evolution. Helping undergraduates accept evolution involves multiple teaching strategies, including teaching evolution with a reconciliatory approach, increasing their knowledge of evolution, and introducing role models (scientists who maintain religious beliefs) to the students. However, because some students have higher scientific reasoning abilities than others, they may find certain evolution teaching strategies more beneficial than others. In our study, we assessed scientific reasoning ability, change in evolution acceptance, and teaching strategy rankings with surveys before and after evolution instruction. We predicted that students who possessed more scientific reasoning skills would rank evolution knowledge above role models when asked which strategy was most influential in helping them accept evolution. However, we saw that scientific reasoning did not appear to moderate the effect of evolution knowledge. Role models were more important in increasing evolution acceptance, regardless of scientific reasoning skills. This reinforces the importance of having a role model present when teaching evolution to religious audiences.

With anthropogenic influence increasing worldwide, it is important to understand how wildlife behavior changes in response to urbanized landscapes. Urban ecosystems represent relatively novel landscapes with unique threats and opportunities that can completely restructure species’ population composition and dynamics. Mule deer (Odocoileus hemionus) have been shown to alter their temporal activity in response to urbanization across their range of the Intermountain West of the United States. In this study, we will investigate the effects of anthropogenic influence on mule deer temporal activity behavior across two distinct life stages: fawning and non-fawning. Data for this study will come from the citizen science camera trapping project, Wasatch Wildlife Watch. The full project area is separated into two study sites: “Rural” and “Urban”. This study will be based around the wild-to-urban interface of the Central Wasatch Mountain Range and the Bear River Mountain Range, which composes some of the most highly recreated portions of the Uinta-Wasatch-Cache National Forest, receiving approximately 9,000,000 visitors annually (U.S Forest Service). We will investigate the proposed differential effects of anthropogenic influence and urbanization on mule deer diel activity patterns in the fawning vs. non-fawning life stages. Also, we will inquire whether intraspecific responses in mule deer diel activity alter interspecific interactions, especially with fawning predators, and how these responses might interact with environmental factors. We predict that anthropogenic influence and urbanization alter the diel activity patterns of fawning mule deer more than non-fawning deer and that the presence and activity of fawn predators (e.g., coyote [Canis latrans]) would have a stronger effect on fawning deer activity than non-fawning deer activity.

It was right before finals. I was involved with the police and helped her family pack up all of my beloved friends belongings and watched as her daddy cried in her room. Words can’t express the agony I saw. Two months later I learned that another roomate (in a different apartment) her cousin had committed suicide. And we were the place everyone gathered. I held her cousin’s (who committed suicide) sister in my arms as she cried. Words cannot express the agony I felt for them.Then on the first day of school this semester (a month ago) my father suddenly passed away from a brain aneurysm. He was at the peak of health. My mom puked from sickness and shock, later got sick with other illnesses, (she’s doing a little better now) then my sister got sick and I was left to care for them on my own. There’s no words to express my exhaustion. The late nights of wandering my house making sure we were safe. Words have no ability to express my agony I’m in. After my roomate passed I created a painting. It’s called my grieving process because it’s of a house, the house represents me. In it through color you can see the process that grief can have on a person. I’m only 25, people say I’m too young to lose this many people. Perhaps they’re right. It’s an eerie painting and pretty odd when you look at it. I have had now three losses that have taught me that sometimes words aren’t enough. That it’s through art I can scream and it is documented. I would love to present on how creating art can be the breathe of fresh air one desperately needs in order to continue on in this fight we call life.

Continued use of antibiotics has driven the evolution of antibiotic-resistant bacteria, which cause infections that prove difficult to treat. Therefore, it is crucial that alternative treatments for bacterial infections are developed. One such promising method, known as phage therapy, utilizes viruses that infect bacteria. However, compared to the high abundance of bacteriophages, relatively few have been isolated and sequenced, with little known about their gene products. Here we have isolated two phages, SummitAcademy and AJGecko, against the host bacteria Gordonia rubripertincta. Gordonia belongs to the Actinobacteria class containing many pathogenic bacteria, including Mycobacterium tuberculosis, and so analysis of SummitAcademy and AJGecko can provide insight into the evolution of this family. Genomic comparison of conserved genes between SummitAcademy and other Gordonia phages identifies 14 hypothetical proteins as unique to SummitAcademy. Subsequent liquid chromatography mass spectrometry (LC-MS) of CsCl-purified SummitAcademy confirms expression of many predicted gene products, verifying the annotation. Several peptides generated through mass spectrometry also provide evidence for extending predicted start sites of gene products. Further characterization of virion proteins and gene products of SummitAcademy can add to the overall knowledge of this cluster of phages and potential phage therapies against Gordonia or related infections.

Authors: Isaac Gillins, Zoe Thompson. Mentors: . Insitution: Utah Valley University. The pro-opiomelanocortin (POMC) gene is expressed in the hypothalamus and pituitary and is cleaved into several peptide hormones. One of these is melanocyte-stimulating hormone (MSH), which is involved in food intake and energy expenditure. A mutation in the POMC gene can result in a rare condition in which the subject displays early-onset obesity characterized by severe hyperphagia (i.e. excess hunger). Affected subjects may also show a lack of pubertal development. In this experiment, we will study mice with a mutation in the POMC gene. They show some of the same symptoms as humans with a POMC mutation, including hyperphagia, obesity & infertility. Specifically, we will investigate the estrous cycle in female mice to determine if they are cycling normally. The estrous cycle, similar to the menstrual cycle in humans, is characterized by changes in reproductive hormones, and can be divided into four stages: proestrus, estrus, metestrus, and diestrus. Cells lining the surface of the vagina have been previously collected using a pipette smear technique. Each stage can be characterized by the proportion of three cell types: epithelial cells, cornified cells, and leukocytes. These cells correspond to the fluctuating hormone levels during the estrous cycle. Images of these samples will be assessed for the composition of cells to determine the stage of the estrus cycle, and whether or not the cycle displays normal patterning. Because POMC-deficient mice are infertile, we hypothesize their estrous cycles may be atypical. For example, the estrous cycle of the POMC-deficient mice may appear in irregular order or with one stage being predominant over the rest. If the estrous cycle is atypical, then we will measure the hormones directly to confirm that the infertility is caused by changes in hormonal regulation. This will help us to understand more about how the POMC gene affects reproductive function.

Insitution: Brigham Young University. Background: American Samoan children face significant mental health challenges, including high levels of depression and anxiety, often escalating to suicidal thoughts and behaviors during adolescence. Addressing this issue, our study collaborated with community leaders in American Samoa to develop and implement five tailored lesson plans aimed at teaching 35 elementary school children resilience strategies for emotional self-regulation. Method: Employing Multimodal Interpretative Phenomenological Analysis (MMIPA), we examined students' drawings depicting their emotions of sadness, anger, and fear before and after the intervention. The analysis focused on understanding the impact of the lesson plans on students' emotional regulation strategies. Results: Post-intervention, our findings indicated a notable improvement in students' ability to regulate their emotions, particularly fear. Through the lesson plans, students acquired practical skills and coping mechanisms, allowing them to better manage their emotions. This positive shift in emotional regulation suggests that the intervention played a significant role in enhancing students' resilience, specifically in dealing with fear-related emotions. Conclusion: Our study underscores the effectiveness of a community-based intervention approach in addressing the mental health challenges faced by American Samoan children. By providing targeted resilience-focused lessons, students demonstrated improved emotional self-regulation, particularly in managing fear. These findings highlight the importance of culturally sensitive interventions and community collaboration in promoting mental well-being among vulnerable populations.

The number of rocket launches per year has been increasing dramatically since 2015, with more rockets launched in the year 2022 than had ever been launched. With the increase in the number of launches per year, it has become increasingly important to understand the impact of rocket launches on the greater environment and community. One important aspect of a rocket launch is the level of acoustical energy that is produced during liftoff. Instantaneous pressure values have been regularly recorded up to 180 dB. Due to these high levels, it’s become important to be able to accurately predict the noise produced by a rocket. One powerful tool used in predicting this sound is the crest factor. The crest factor is an acoustical measurement that shows the difference between the maximum sound pressure (i.e. the crest) compared against the averaged value of the sound pressure. Additionally, this information is vital for planning acoustical equipment in order to avoid measurement clipping. This presentation will be about crest factor analyses performed on the Antares NG-19 rocket launch from August 2023.

This research explores how virtual reality can help children with autism. It explores the effects of an intervention using virtual reality to assess the usability of virtual reality for children with autism.There are more than 200 studies that show that video modeling is a viable way to teach students with autism various skills. Research has started to explore if virtual reality is also a successful way to teach students with autism similar skills. Different studies have been conducted regarding social skills and cognitive skills and how they can be taught using virtual reality. There is very little research about fine-motor skills and virtual reality for individuals with disabilities. Our research adds to that research, but specifically explores fine-motor skills and the feasibility of using virtual reality with children with autism. The study uses a single subject research design with 5-10 participants with autism. Before starting data collection, the participant completes a brief tutorial for how to use virtual reality. One tutorial is for how to use the controllers and the other is for how to use the hand-tracking feature that allows the participant to use their hands instead of the controllers. The study is an alternating-treatment design. The individual is given a specific task to complete using the playroom items found in the “First Steps” application on the Oculus Quest. For example, they are asked to stack blocks, throw paper airplanes, etc. They either complete the task using the controllers or with the handtracking feature based upon a random schedule and the latency of the trial is measured. The data compares hand-tracking and controllers and measures whether the participant is getting faster with every trial. It was hypothesized that the students will be able to learn how to use the virtual reality interface and that they will be able to generalize the skills learned to other settings and/or skills, and that the interventions will be viewed by the participant and parents as socially valid ways to learn. It was anticipated that the participant will get increasingly faster at completing the tasks for both hand-tracking and with the controllers. It was also anticipated that the rate of completing tasks with controllers will be faster than that of hand-tracking. Preliminary date has shown this relationship to be true. Future research will explore the specific practices of how virtual reality can be best used for children with autism.

Authors: Nathan Vaughan. Mentors: Jeffery Tessem. Insitution: Brigham Young University. Diabetes Mellitus is a chronic disease characterized by a loss of functional beta cell mass, and impaired glucose homeostasis. Elevated glucose levels in the body are known to be the cause of a plethora of debilitating illnesses. Hyperglycemia negatively effects beta cell function, resulting in impaired insulin secretion and cell death. Two key transcription factors involved in beta cell development, function, and proliferation are Nkx6.1 and Pdx1. We have shown a binding interaction between these Nkx6.1 and Pdx1 and have shown that they co-regulate various genes necessary for beta cell maturity and function. Preliminary data indicate that elevated glucose concentrations downregulate Nkx6.1 mRNA and protein, as well as Pdx1 mRNA. However, the effect of elevated glucose concentrations on Pdx1 and Nkx6.1 binding interaction and subsequent function remains largely unexplored. Here we demonstrate the effect of hyperglycemia on the Pdx1-Nkx6.1 interaction, and the effect on expression of Pdx1 and Nkx6.1 downstream target genes. Understanding the effect of hyperglycemia on this interaction will allow us to better understand the stress that a beta cell is under during diabetic conditions, and to develop interventions to ameliorate these effects.

Authors: McKayla Pehrson, Emily Hyde. Mentors: Lyndsey Vader. Insitution: Utah Valley University. Emily Hyde and McKayla Pehrson acknowledge that social factors and life circumstances can provide barriers to success, defined as the ability to implement life skills such as self-discipline, creativity, and perseverance. They address how practitioners and educators can use dance and music to reduce barriers. Hyde and Pehrson engage in discourse analysis of recent scholarship, analyzing trends and outcomes in the cognitive, emotional, physical, and social benefits of arts-based interventions. Their research asks: What cognitive benefits are identifiable through dance and music training? What life skills are taught through the study of both music and dance? What are the benefits of dance and music in advancing different learning styles? What is the importance of administrative support and community-academic partnerships when it comes to arts-based learning? Importantly, their research examines specific national and international training programs that use music and dance as a Life Coaching methodology. The presentation of their discursive findings foreshadows field work and data collection that they will undertake in the summer of 2024. Hyde and Pehrson’s research focuses on the impact of teaching essential life skills through dance and music education. While dance education scholarship addresses positive learning outcomes of arts access, contemporary research does not adequately address how dance educators can receive training as life coaches to enhance their teaching practices. Their research will provide valuable discoveries advancing the conversation about how dance and music are beneficial to the development of life skills and crucial for the success of young learners. Simultaneously, they will offer insight around training programs that help prepare future dance educators to teach these life skills in the classroom.

The genes are expressed in the prostate gland. Both genes have several polymorphisms. Here we examine the association of rs4648298 (A-G transition) and rs20417 (G-C transversion) polymorphisms and prostatic diseases. This research was approved by the Utah Valley University IRB.Materials and Methods: DNA was extracted from a blood sample of 56 healthy volunteers, 51 volunteers with benign prostate hyperplasia (BPH), and 61 volunteers with clinical prostate cancer (PCa). Genotyping was conducted through PCR-RFLP analyses. The restriction enzymes used were BaeGI (for rs4648298) and AciI (rs20417), respectively. Alleles with the restriction site were considered recessive. The association was inferred through statistical analyses of the distribution of the genotypes (BB, Bb, and bb or AA, Aa and aa), and allele frequencies among the controls and the affected groups. A p-value of ≤0.05 was considered significant.Results: The distribution of the genotypes is in Hardy-Weinberg equilibrium for all three groups. The b allele of the COX-1 gene is extremely rare (less than 3%), and no significant association between the B or b allele or BB, Bb, and bb genotypes and prostatic disease was observed. The a allele of the COX-2 gene is more common in the BPH group (p=0.011), but not the PCa group (p= 0.472) or the combined affected group (p=0.068) compared to the control group.Conclusions: There is no association between the rs4648298 polymorphisms of the COX-1 gene and prostatic diseases. The a allele of the rs20417 polymorphisms of the COX-2 gene is associated with higher risks of BPH and possibly PCa. The small sample size, sampling from one ethnic group, and the low distribution of the b allele in the Lebanese population are limitations of this study.

As the world’s human population continues to concentrate within urban areas and these landscapes continue to expand worldwide, wildlife is under pressure to adapt to novel environmental disturbances. Along urban-wildlife gradients, and especially within less developed areas, human recreation can affect wildlife behavior. These effects may be most apparent during peaks in human recreational activity. In addition, climatic conditions such as aridity and precipitation can also alter wildlife behavior. Understanding the interactions between these two pressures, human activity and climate, can help us understand how wildlife behavior will be affected as human populations grow and climate warms. In this study, we will use data from a large-scale citizen science camera trapping project to assess whether periodic increases in human recreational activity paired with arid climates will elicit behavioral responses across multiple mammal species in northern Utah, U.S.A. Specifically, we will assess whether increases in human recreational activity during the weekend affected mammalian temporal activity patterns at the community-wide and species-specific level, taking into consideration if these trends are amplified in areas that are arid and low in precipitation. I hypothesize that increased human recreational activity will alter wildlife behavior, in general, however this change in behavior will be amplified in drier, hotter areas. I predict that during the weekends human activity will increase, leading to general decreases in activity, mobility, and breeding behavior across species, and this will be amplified in hotter and less vegetated areas. However, I predict that naturally diurnal species will be more affected than nocturnal species as they attempt to avoid overlap with humans, leading to changes in species-species interactions.

Goddess of Spring and Death(2023) is a dance for film co-created by three Utah Valley University undergraduates focusing on retelling of the Ancient Greek myth of Persephone and Hades through a new perspective. Throughout time, stories are often retold; however, this myth has rarely been told from Persephone’s point of view. With a collaboration between the two disciplines of ballet and film, there was opportunity for a more intimate viewing of narrative-based choreography with creative camerawork and post-production editing. The purpose of this presentation is to disseminate research from the dance for camera: Goddess of Spring and Death(2023) in addition to how this collaboration affected both disciplines. The traditional myth tells of the story of Hades kidnapping Persephone to the Underworld and marrying her, typically focusing on the actions of Hades and Demeter. However, the researchers’ collective focus of this narrative was to include Persephone’s agency. The narrative still follows a similar plot to the original myth however, Persephone’s character was more developed as she was given the agency to go into the Underworld and eat the pomegranate of her own free will. An unlikely format for this narrative, the respective areas of ballet and film have become a popular collaboration, especially post-COVID. Stereotypically, narrative ballets are commonly performed on a proscenium stage while film works with verbal narratives. Both disciplines were challenged to explore and collaborate together in a field that is not yet standard. The experience for all on the project, including the dancers and crew, was that of gaining new learning that can be applied in the post-graduate fields.

Utah Lake is the third-largest freshwater body west of the Mississippi River and serves as a vital resource for just over 600,000 Utah Valley residents through agriculture, residential and recreational purposes. In addition to its utility, Utah Lake provides a haven for biodiversity for numerous species within its wetlands. Despite its utility and importance, the lake faces two significant challenges in the form of Trace Metal (TM) pollution and the encroachment of invasive plant species known as Phragmites australis (P. australis). Despite considerable investments of time, money, and resources by various state agencies to address these concerns, their success has been limited due to the agency’s isolated efforts for these large multifaceted issues. TM, though naturally occurring in the environment, has been found to be toxic to both people and the ecosystem when at elevated levels. P. australis, is a robust and fast-growing macrophyte, possessing remarkable adaptability to and tolerance for poor soils, enabling it to rapidly outcompete native species. Due to P. australis resilience and aggressive nature, many colonies have grown around the lake regardless of soil conditions. Studies have shown that P. australis has been utilized for remediation purposes around water bodies by extracting TMs from sediment. While P. australis must be addressed, can it be used as part of the solution by identifying TM polluted areas? This study aims to discern the variety in TM absorption by P. australis in both unpolluted and polluted sites in the wetlands surrounding the hyper-eutrophic Utah Lake. We selected nine sites around Utah Lake, considering their land use and proximity to pollution sources. At each site, three replicate samples encompassing P. australis, soil, and water were collected. These samples underwent a meticulous process, including washing, weighing, grounding, sieving, acid digesting using a CEM MARS 6, and analysis for TM content within an ICP-MS. Our preliminary findings reveal that in both unpolluted and polluted sites, soil concentrations of As and Cd exceeded background levels (11.73, 1.53 in unpolluted sites, and 27.47, 6.63 in polluted sites, respectively). Notably, in select polluted sites, such as UVU, P. australis displayed a remarkable capacity to hyper-accumulate As, with a transfer factor of 167.14% compared to the lowest unpolluted sites, like Lindon, which showed a rate of about 10%. Across all sites, the accumulation of Cr was relatively consistent (ranging from 17.13 to 19.7 ppm), irrespective of biomass. The examination of TM concentrations, transfer factor rates, and TM accumulation based on biomass suggests that P. australis may serve as a valuable biomarker for identifying TM-polluted sites. This research holds significant relevance, as it could offer state agencies a swift and effective means to pinpoint TM-polluted areas. Moreover, the areas where P. australis is thriving may be leveraged for phytoremediation efforts in TM-contaminated sites, providing an environmentally friendly solution to address this pressing concern.

Authors: Hannah Smith. Mentors: Jeff Parker. Insitution: Brigham Young University. The Arabic language uses a rich system of patterns called verb forms to create verbs with related meanings from roots made of consonants. For example, the root k-t-b, in form I, kataba, means ‘to write.’ When it appears in form II as kattaba, it means ‘to make someone write.’ In form III, kaataba, it means ‘to exchange letters,’ ‘to correspond’ (Wehr, 2019). There are ten commonly used verb forms, although not every root is used in every form. As Arabic has been exposed to English and speakers borrow verbs from English into their Arabic, they make choices about how and whether to integrate these foreign words into the verb forms. For example, the verb ‘to block (on social media),’ with the derived root b-l-k, is used in form II, ballaka, ‘to block.’ Other borrowed verbs, however, don’t get integrated in this way. Instead, they are used as a noun with a native Arabic verb, usually ‘amila, ‘to do.’ For example, English ‘to delete’ becomes ‘amila daliit, literally ‘to do a delete.’ This study aims to understand what factors influence when and how completely borrowings from English like these are integrated into the verb forms in Jordanian Arabic (JA) by interviewing university students in Amman, Jordan. The interviews are primarily focused on four forms in which borrowings in JA frequently appear (Salem, 2015). Initial data from a group of eight participants shows a general acceptance for the borrowings in their base forms, with much more variation in speakers’ intuitions regarding their usage in other forms. For example, all eight participants perceive ‘to block,’ ballaka, as a completely acceptable word used by most people. However, only two participants felt the same way about its counterpart form, taballaka, ‘to be blocked,’ whereas two other participants perceived it as something no one would ever use. Furthermore, some participants perceive verbs that rely on ‘to do,’ such as ‘to delete,’ to be in the beginning stages of integration, with three of eight interviewees stating that some of these verbs actually are acceptable in verb form II. Thus far, the perceptions of all the borrowings seem to indicate that speakers believe that integration of borrowed verbs is a gradual process. Furthermore, in addition to other factors, the extent to which the verbs are integrated in JA seems to be affected in large part by cultural perceptions of how foreign the verbs are, a factor that has not been noted in previous studies on the subject.

How reliable is emotional facial expression coding within and across raters? Background Emotion, described as “physiological forces, located within individuals, that bolster our sense of uniqueness....” (Katriel, 2015, p. 57) is a critical aspect of day-to-day communication. For people with acquired language disorders post-stroke (i.e., aphasia), this interaction is particularly important due to relatively spared emotional processing, which has the potential to either facilitate or interfere with language processing (see e.g., Harmon et al., 2022; Ramsberger, 1996). The present study is part of a larger project, which seeks to determine whether people with aphasia exhibit more emotional facial expressions during personal narrative discourse than adults who do not have aphasia and whether these expressions are more emotionally arousing. The present study specifically seeks to investigate the reliability of facial coding by comparing average frequency and intensity of emotional facial expressions both within and across undergraduate student coders. Methods In order to quantify emotional facial expression frequency and intensity, undergraduate research assistants are trained to code facial expressions using a modified FACES protocol (Kring and Sloan, 2007). The modified protocol will be used to code emotional facial expressions of video footage that was obtained from participants while they told personal narratives (e.g., talking about an illness they experienced or an important life event). First, research assistants identify the baseline facial expression for each participant. Next, research assistants code transitions from a neutral expression to an emotional facial expression for valence (positive/negative) and intensity. Intensity ratings are scaled from 1 to 4 depending on how many units of the face are involved within the corresponding facial expression. Using this protocol, research assistants will begin facial coding after they are trained and demonstrate mastery by attaining 80% agreement with a master code. Upon completing initial data coding, research assistants will be assigned to recode 10% of previously completed video samples as well as 10% of samples that were previously coded by other coders. This secondary coding will be used to measure intra- and inter-rater reliability across dependent variables: frequency of emotional facial expressions, intensity of positive facial expressions, and intensity of negative facial expressions. Average frequency of emotional facial expressions will be calculated as the number of facial expressions produced per minute within a given sample. Intensity of positive and negative facial expressions will be calculated as the mean intensity within each valence respectively. The average frequency and intensity of initial and reliability codes will then be compared using Pearson’s correlation coefficient. Anticipated Results We anticipate that intra- and inter-rater reliability will be above 0.8. Through a strict training process, research assistants will calibrate their coding to achieve 80% agreement with the master code. We anticipate this training process to produce effective intra- and inter-rater reliability. Findings will be important for determining the reliability of facial coding procedures and trustworthiness of data for answering questions related to the longer-term project.

Authors: Harlan Stevens, Arwen Oakley. Mentors: Stephen Piccolo. Insitution: Brigham Young University. The number of scientific journal articles published per year now exceeds one million. To help maximize the impact of these articles, researchers must ensure that images in the articles are accessible to people with color-vision deficiencies (CVD). Up to 8% of males and 0.5% of females experience at least one form of color-vision deficiency, thus making it difficult for these individuals to discern patterns in images that use particular color combinations. We sought to shed light on this problem by estimating how often published images use color combinations that are unfriendly to people with a CVD. Examining 6,000 images published in biology-oriented research articles published in the eLife journal between 2012 and 2022, we identified images with potentially problematic color combinations. Using quantitative metrics and manual review, we estimate that 13% of these articles would be difficult for people with moderate-to-severe deuteranopia to interpret. We used a convolutional neural network to automate the ability to label images as being problematic for people with moderate-to-severe deuteranopia. The machine learning model successfully classified images in a testing dataset with an auROC of 91.3%. Based on these results, we created a web application that allows users to upload images and view estimates about whether the images are CVD-friendly. Such efforts are critical to ensuring that papers published in the biology literature are interpretable to diverse audiences.

Petal projections are defined as a special class of knot projection with a single multi-crossing, which causes the formation of loops entering and exiting the crossing. The relative height of the strands as they pass through the multi-crossing is always an odd-length permutation. Recent research has described the complete set of moves which is sufficient to relate any two permutations that describe the same knot. In this talk, we will discuss potential novel knot invariants arising from isotopy of knots and their petal projections.

Fifty years ago, Brazilian scholar José de Nascimento Morais Filho rediscovered Maria Firmina dos Reis (1825–1917), Brazil’s first female—and first black female—novelist. Morais published a biography about Reis, including in it as many of her works as he could find. During her lifetime, Reis published the novel, Úrusula, musical compositions, short stories, and poems, though it was only through Morais’ biography that some of these works were reintroduced to the general public. Reis used writing to challenge the flaws she saw in society. The most glaring of these was slavery, with which she had first-hand experience, her Afro-Brazilian mother and African grandmother having been enslaved. Because of this, she has gained notoriety as not only the first female novelist in Brazil, but as an ardent abolitionist. However, the people living in her hometown of Guimarães, Maranhão, knew her—and continue to remember her—quite differently. To them, she was a teacher, whose life’s work was to educate and elevate as many lives as she could. She founded a school that taught both boys and girls and refused to use corporal punishment. Using information gathered on a summer research trip to Maranhão, Brazil, including a visit to the archive where Reis’ works were rediscovered and a visit to Guimarães, I will compare the prevailing understanding of Maria Firmina dos Reis as an abolitionist writer with the powerful and living legacy that I experienced first hand in Guimarães. I conclude by discussing the impact of viewing Maria Firmina dos Reis as both an abolitionist and a teacher, how these views complement each other, and how seeing both sides of her story can help us better understand how activism can manifest in many different ways.

Attorneys play an important role in protecting the rights of the defendant and maintaining fair courtroom outcomes. This project compared self-reported fairness between court customers with and without an attorney representing their case. 372 Provo City Justice Court customers reported their perceived fairness in a 10-item survey, validated by national court assessment tools. Statistical analysis was performed, and a linear regression model revealed no association between legal representation and fairness. This indicates that both groups reported the same level of fairness, regardless of attorney representation. While evidence suggests that court customers with an attorney may receive better outcomes and less jail time, this was not reflected in court customers’ perceived fairness. We suggest a court navigator be available to court customers, so they can better understand how fairly they are being treated.

Deep reinforcement learning (DRL) continues to demonstrate remarkable efficacy in pattern recognition and problem-solving, particularly in domains where human intuition falls short. In the realm of knot theory, an important challenge revolves around constructing minimal-genus slice surfaces for knots of varying complexity. In this presentation, I will outline a novel approach that leverages the power of DRL to tackle this difficult problem. Using braid representations of knots, we train reinforcement learning agents to construct minimal genus slice surfaces by finding sequences of braid transformations that are optimal with respect to a given objective function. This provides a template for attacking other computationally difficult problems in topology and pure mathematics using reinforcement learning.

The Hyrum Smith Papers project, patterned after the Joseph Smith Papers, is a scholarly initiative at Brigham Young University aimed at collecting, transcribing, analyzing, and publishing selected extant documents associated with Hyrum Smith, the older brother of Joseph Smith, Jr.—key figures in the early history of The Church of Jesus Christ of Latter-day Saints. With a focus on illuminating the often underappreciated contributions of Hyrum Smith, this project examines a wide range of historical documents. These include, but are not limited to, personal correspondence, journals, sermons, certificates, legal documents, land records, ecclesiastical and administrative documents, and others. The purpose is to contribute to a deeper understanding of Hyrum’s role, leadership, and influence within the context of the American religious, social, and political climate of the early 19th century. The goal of this research is to publish a volume with transcriptions, narratives, photographs, and illustrations associated with Hyrum Smith’s life. This UCUR oral presentation will provide an overview of how relevant documents are identified and incorporated into our corpus.

Braid closures provide a way to study knots and links in 3-space via group-theoretic techniques. Several important open problems in low-dimensional topology can be reformulated as problems in combinatorial group theory via a particular braid invariant called the band rank. In this talk we will describe the band rank and techniques for computing this quantity which draw on tools from reinforcement learning.

We examine the extreme version of low data quality by identifying census US enumerators in the US who fabricated entire families. We provide clear evidence of fake people included in the census in Homestead, Pennsylvania. We use the features of this case study to identify other places where there seem to be fake people. Our automated approach identifies census sheets that have much lower match rates to other census records that would be expected, given the characteristics of the people recorded on each sheet.

The agricultural laborers’ riots that occurred in England from 1830 to 1831, commonly called the Swing Riots, have been well-studied over the past fifty years. In recent years, historians have sought to better understand individual protests were rooted in local causes and social networks, however, there are still gaps in historians’ understanding of how these events related to urban protests going on around the same time. Through an in-depth exploration into the Norwich weavers’ riots in 1829 and the fires in Swanton Abbott, Norfolk in January 1831 this research attempts to show how the changing relationship between urban and rural communities could link urban and rural protest movements in multifaceted ways. Special attention is paid to the lives of some of these protests’ key participants (Richard Knockolds and the Davison brothers), including their backgrounds, motivations, and the ways their actions were memorialized both in the city and the country. When these two protests are situated in the context of urban-rural relations, it becomes clear that they were part of an active renegotiation of the relationship between city and country brought on because the pressures of industrialization were pushing the two together in ways that many found threatening. Each of the people involved had a different vision for what this relationship should look like, as well as a vested interest in ensuring this vision prevailed. By foregrounding how these participants approached the boundaries between urban and rural worlds, this research emphasizes the ways this boundary was a crucial point of contention in early industrial Britain.

During cellular mitosis long DNA molecules are first split and then separated with one copy being transferred to each of the daughter cells. A class of enzymes known as topoisomerases assist in the separation of the two strands of DNA, though the precise mechanism by which they work is unknown. In this talk we will discuss attempts to model topoisomerase action using techniques from reinforcement learning.

The purpose of this study is to better understand what it means to be an American by examining perceptions of national identity through the lens of Brazilian Americans living in Northern Utah. With this purpose in mind, we hope to add to the discussion of national identity during a time when the United States' title as a “melting pot of nations'' is called into question. The study focuses on the question: How do Brazilian Americans living in Northern Utah perceive their own national identity? Additionally, it seeks to answer the following subquestions: Does a pluralistic national identity exist among Brazilian Americans in Northern Utah?; If a pluralistic national identity exists among Brazilian Americans in Northern Utah, do the two identities coexist, or is there a synthesis of the identities and what does that look like?; How do they perceive American national identity?; How is American National identity influenced by Brazilian Americans in the United States? Working with local Brazilian businesses, cultural groups, families, and individuals, we collected data through a variety of ethnographic methods including participant observation, semi-structured interviews, mapping, sonic recordings, oral histories, photo, video, and media usage. We then used thematic qualitative data analysis methods, finding that Brazilian Americans in Northern Utah see their identities as pluralistic as well as that Brazilian and American identities coexist, operating in different spaces. The results show how American national identity is fluid and complex, existing as a companion to other identities, demonstrating how “Brazilianess” contributes to “Americanness” by creating more empathy, understanding, and union in the United States.

Between the years of 1988 and 2016, there has been a staggering figure of individuals, in the hundreds of thousands, that have been incarcerated in what has been recognized as a mass incarceration phenomenon intended to make our nation safer using a “tough-on-crime” approach. As of 2020, the number of people incarcerated is slated to be around two million, and the prison population continues to grow. Along with this stunning growth in our carceral systems has also come the realization that without investment into incarcerated individuals, prison systems will continue to grow without serving any meaningful purpose to both incarcerated people and their communities once incarcerated individuals have served their terms. As a result, educational programming has been implemented in multiple prisons across the country, and following suit is the implementation of visual, theater, and writing-based arts programs. While the original intention of many arts education programs in carceral environments is to serve as a form of rehabilitation, therapy, and assimilation back into society for those that are incarcerated, many incarcerated or formerly-incarcerated artists perceive the arts opportunities offered to be much more valuable and fulfilling than a means of emotional regulation and personal growth; some see it as a way of connection or re-connection with their families, friends, and communities, others see it as a potential career path and redirection of the trajectory of their lives, and some see it as a reclamation of their identities and voices beyond their criminal history.

Authors: Sven Wilson, Joseph Price, Hannah Hammond, Katharine Wilson. Mentors: Joe Price. Insitution: Brigham Young University. Research suggests that environmental and behavioral risk factors often shared by spouses will result in similar spousal lifespans. This is seen most powerfully in the well-documented tendency for the hazard of mortality to rise immediately after spousal loss, thereby causing a greater concordance in spousal lifespans. This is sometimes referred to as "broken heart syndrome," and a widowhood effect on mortality has been observed in multiple large population studies in many countries. We employ a new dataset from the United States containing over 2.8 million couples drawn from the 1940 census who were born between 1880 and 1920 who are linked to US Census Schedules through 1940 and to the wiki-like genealogical data source Family Search. To account for the presence of assortative mating, we employ a strategy where the lifespan of the spouse's siblings is used as an instrumental variable for spousal lifespan. We find only a small amount of assortative mating on the basis of lifespan, but considerable sorting based on education and income. Our simple IV model finds a statistically significant causal relationship between the death of both husbands and wives on the lifespan of their respective spouses, and those effects are roughly twice as big as the OLS estimates. An additional year of life for the spouse adds .11 years to the husband’s lifespan; and .157 years to the wife. The larger effect on women’s lifespan is in opposition to most of the literature on the widowhood effect.

Social connection is critical to understanding how individuals interact with one another and form social bonds in groups. Our research evaluates the effects on social connection based on the Ecology of Family Experiences framework, which considers the interplay between three domains: family, activity, and time. We believe that the EFE is a transferable framework that will have important social implications for understanding interpersonal relationships and designing experiences intended to increase social connection. In this study, we examine the relationship between social connection and two variables: 1) social interaction, or the behavior between two or more people crossing paths. Social interaction considers joint or parallel interaction styles between people; 2) self-disclosure, or interaction where one intends to willfully and deliberately divulge something personal to another. We hypothesize that social interaction and self-disclosure influence social connections outside the family context. We seek to shed light on the mechanisms that shape and alter the quality and depth of interpersonal connection. In our experiment, we used a 2x2 quasi-experimental design. Participants were assigned to one of four conditions varying in self-disclosure (high vs. low) and social interaction (joint vs. parallel). Self-disclosure questions asked participants to answer prescribed questions, including highly personalized questions (high disclosure) and non-personalized information (low disclosure). Participants either interacted with a partner (joint) or wrote responses next to a partner without verbal communication (parallel). Social connection was measured using the Inclusion of Others and Self Scale. The sample consisted of 148 university students. The average participant was a white, unmarried, 20-year-old from a middle- to high-class economic background. Data analysis was conducted using mixed model techniques that took into account the unique dyadic relationship of each pairing. Results suggested a significant interaction between self-disclosure and social interaction (t = 2.354, p < 0.05). With high self-disclosure and joint activity having a mean of 4.54, high self-disclosure and parallel activity having a mean of 2.33, low self-disclosure and joint activity having a mean of 3.47, and low disclosure parallel activity having a mean of 2.01. These findings highlight the importance of self-disclosure and social interaction styles in influencing social connection, extending the applicability of the EFE framework beyond the family unit.

Implicit bias occurs automatically and unintentionally based on a person’s lifetime experience and cultural history (National Institutes of Health, 2022; Handelsman & Sakraney, 2015). In this study, implicit bias is evaluated through the lens of a transformative diversity, equity, inclusion, and belonging business course. DEIB originated in the 1960s in response to equal employment and affirmative action laws (Sarrett, 2022). Studies show that Millennials and Gen Z generations are the most diverse populations ever in the United States (Stamps & Foley, 2023). Benefits of DEIB include the creation of a more unified, diverse, and successful workplace, less biases in hiring, team development, promotions, and who companies do business with (El-Amin, 2022). This study’s theoretical framework is based on the transformative learning theory which seeks to understand and promote human development through learning. Transformation is more than "knowing more" through time; when a learner is transformed by education they undergo a shift in perspective, and after that shift, they cannot go back to see the world the way they once did, at least in some small way (Wichita State University). The class was designed with experiential learning approaches and introduces a variety of DEIB concepts such as privilege, unconscious bias, assumptions, and intersectionality. Students interacted with a variety of experiential components such as DEIB events, panels, and interviews which addressed various minority groups. At the beginning of the DEIB course, students completed an IAT test focused on racial bias. The IAT test is known as the Implicit Association Test that uses positive and negative connotative words in association with pictures of minority groups to measure automatic reactions targeting an individual's level of implicit bias towards one minority group versus another. After students completed the racial IAT test, scores were recorded representing the level of implicit racial bias students held towards white people vs. black people. At the conclusion of the 14-week-long course, students completed the same IAT test on racial bias. Scores were recorded once again, comparative with previous IAT scores, to evaluate whether the amount of racial implicit bias had changed as a result of participating in the DEIB course and its curriculum. Data was then analyzed visually comparing the means from the pre to post test results. The data was analyzed using this method because the sample size was not large enough to return what the researchers considered to be reliable results. More data is available for this study, but has not been cleaned and matched, this process is currently taking place. Once the data is available, the researchers will use paired sample T-tests to conduct a full analysis. Additionally, descriptive analysis will be represented in the form of histograms of pre and post test scores observing the progression towards less implicit bias. The mean for the pre-test was .78 (sdv=1.34, n=171) and the post-test was .63 (std=1.38, n=144). Our sample size was 181 participants with 25 that chose not to answer. Demographics of participants consisted of 66% Caucasian, 3% Hispanic, 2% Asian, 2% Native Hawaiian, 1% other, and 26% who chose not to respond. The average age of participants was 21. Gender of participants consisted of 121 females and 34 males. Visual examinations of the means suggest there was migration toward 0, which would represent little to no bias and the class was making a difference in participants’ implicit bias scores. This study underscores the utility of DEIB instruction in promoting changes in bias. The impact of changes in implicit bias through this learning coupled with DEIB principles in a transformative way will greatly influence the workforce for generations to come.

This figure is expected to rise to about 640 million by the year 2030. Metabolic stress is known to drive the development of the disease. The pancreatic β-cell which is responsible for producing and secreting insulin in response to elevated blood glucose concentrations is particularly sensitive to metabolic stressors. Therefore, understanding the molecular character of β-cells is important to curing diabetes. Nkx6.1 is an important β-cell transcription factor critical for proper β-cell development and function. Our lab has shown a potential interaction between Nkx6.1 and PACS1 in β-cells. PACS1 is associated with the Trans-Golgi network and is involved in protein maturation by sending newly synthesized proteins to their intended target inside or outside the cell. We know that insulin is synthesized in the ER and sent to the Golgi for vesicle packaging. We hypothesized that PACS1 helps sort insulin in the Trans-Golgi network, and that interaction with the β-cell transcription factor Nkx6.1 is essential for this process. Therefore, the study of the interaction between Nkx6.1 and PACS1 may provide a greater understanding of diabetes and insulin secretion in β-cells. Here, we present the results of our investigation of the link between Nkx6.1, PACS1, and the Golgi apparatus. We present data validating the Nkx6.1-PACS1 interaction, the cellular location of the interaction, and the effect of changing glucose concentration on this interaction. These results will help deepen our understanding of how the Nkx6.1-PACS1 interaction works to ensure proper β-cell function.

Prior work from our lab has demonstrated that social media usage can be highly beneficial for autistic young adults. Simultaneously though, it can lead to physical or social harms. In order to better support the autistic community on social media, it is important to provide educational content on social media safety. As such, the BYU Social Technology and Privacy Lab has developed, and is currently validating, educational slides, quizzes, and practices modules.My work focuses on creating a gamified education app that will host these materials. This app will utilize effective gameplay strategies in order to motivate autistic users to meaningfully consume the materials. This app will be designed to cater to the needs of individuals in this community.The project started with a thorough literature search in September. I reviewed prior work on gameplay design and educational psychology of both neurodiverse and non-neurodiverse populations (n=12). We will be engaging in participatory design sessions that allow participants to contribute their own ideas and designs. These designs will be pieced together to form a preliminary prototype of the app. Based on these findings, a mobile application will be built and deployed in the autistic community. Statistics on user performance and the amounts of time they spend on the materials will be collected. These statistics will be analyzed and compared with the non-gamified version of the app. We will also collect qualitative data on participant attitudes towards the app.

FPGAs are a type of reconfigurable computing chip that are often used in mission critical systems in various applications including aerospace, defense, and telecommunications. Hardware netlists are generally converted into a bitstream and loaded onto an FPGA board through vendor-provided tools. Due to the proprietary nature of these tools, it is up to the designer to trust the validity of the design's conversion to bitstream. However, motivated attackers may alter the CAD tools' integrity or manipulate the stored bitstream with the intent to disrupt the functionality of a design.We have put forward a novel approach to verify functional equivalence between a synthesized netlist and the produced FPGA bitstream using a structural comparison algorithm. This presentation aims to demonstrate the fault-injection testing algorithms designed to prove the veracity of our approach. The fault-injection testing algorithms involve making manipulations to wire connections and initialization values in LUTs (lookup tables) from a bitstream reversed netlist, then running our comparison algorithms on the corrupted netlist and the original synthesized netlist to show that the algorithms will catch the errors.

Finding ways to improve crop durability through 3D modeling has tremendous potential to help save plants, time, and resources. Currently, there are many important material properties of maize stalks that have not yet been measured, which presents challenges in creating accurate 3D models. Through sensitivity analysis, it was determined that one of the most critical unknown material properties of maize stalks for creating accurate models is the transverse shear modulus. In this research, we created a testing procedure to determine the shear modulus as accurately as possible. Each sample was put in a torsion test to determine the relationship between the torsion torque and the torsion angle. Both fresh and dry samples were tested in addition to samples with and without the pith. Our team implemented methods to minimize inaccuracies from slipping, cracking, and other imperfections in all elements of the stalks. The transverse shear modulus that we have determined will help to more accurately model maize stalks, thereby making future tests by modeling more efficient and working to provide a path towards improved global maize harvests.

Virtual Reality: The Next Step in Technology-Based Education Virtual Reality (VR) technology offers numerous educational opportunities that can enhance high school curriculum. The use of technology in the classroom has been rapidly evolving since the development of the accessible internet. Laptops, tablets, online learning platforms, and interactive projections are several of the technological developments, and now VR appears to be one of the next steps in that evolution. As VR continues to become more affordable and more advanced, there is a commensurate increase in opportunities to enhance curriculum, instructional techniques, and student engagement. For example, VR enables students and teachers to go on virtual field trips to places that are relevant to class material without the challenges and costs of leaving the classroom. The purpose of this study was twofold; (a) to investigate the different applications of VR technology that can be used to enhance high school social science curriculum, and (b) to summarize some of the main benefits and challenges associated with implementing VR in the classroom. The results of this study indicate that VR technology has considerable potential to enhance both the learning experience and student engagement by providing immersive learning opportunities, but these opportunities are unlikely to be widely utilized in the near future.

Using members of The Church of Jesus Christ of Latter-day Saints as a case study, this research explores text reformatting that may address the unmet needs of religious people with aphasia. Aphasia is a language disability that sometimes occurs after a stroke or traumatic brain injury. It can affect both expressive and receptive language, including reading ability. Several studies have already explored what text adaptations are generally preferred by or aid comprehension in this group. However, the unique regard of sacred text may elicit different needs and preferences for those experiencing aphasia. For example, although text adaptation for people with aphasia often includes text simplification, some may find inherent spiritual value in the original wording of scriptural text. Therefore, in this study, other adaptation options are explored, such as font changes and verse spacing. Passages from texts considered holy in the Church of Jesus Christ, such as the King James Bible and the Book of Mormon, have been reformatted in potentially helpful ways. Latter-day Saints with aphasia are being recruited to give feedback on these samples. They will indicate their formatting preferences on a visual scale, and their comments and feedback will also be coded qualitatively. This research will provide guidelines on what text adaptations are most appropriate and helpful for religious texts. Although the samples are specifically geared towards members of the Church of Jesus Christ of Latter-day Saints, the design principles may prove useful for texts used in other faiths as well.

From the weekly grocery run to the daily commute to work or school, transportation plays a central role in meeting the basic needs of nearly every American family. Unfortunately, not everyone has equal access to safe, convenient, and efficient transportation. When not carefully planned and implemented, the advancement of transportation infrastructure and technology often favors high income communities. For example, in many areas, shared electric scooters and bicycles have been made more widely available in higher income neighborhoods, leaving lower-income communities with limited access to these micro-mobility options. The result of these and other similar developments is increased economic disparity and barriers to opportunity. One such transportation advancement for which careful implementation is vital is Wireless Power Transfer (WPT) technology for electric vehicles (EVs). WPT technology offers the potential for EVs to charge while in motion on the roads, thereby accelerating the adoption of EVs, and building a cleaner tomorrow. Through this research, we seek to contribute to a future of equitable integration of WPT technology into roadways across America. Because the demographics of Indianapolis closely resemble the US overall, a simulation was run with drivers in the city, using sample data from the US and Indianapolis. The simulation was then used to determine potential locations in which WPT technology could be effectively implemented. Informed by this and other research, WPT technology can be integrated in an intentional manner ensuring equitable access for people of any socioeconomic status.

The application of origami principles in mechanical design has led to novel approaches for dealing with the unique challenges of space applications by improving packing efficiency and increasing customizability. An innovative origami pattern within this context is the "flasher pattern," characterized by its geometric panels and circular deployment. The objective of this research is to develop a robust methodology for optimizing the placement of circular optical wafers within the polygonal flasher panels. These panels have varying polygonal sizes and shapes, and the wafers must be placed precisely in each panel to maximize optical properties for a LIDAR space telescope application based on the flasher pattern. This optimization utilizes existing optimization functions in MATLAB and original code. To achieve this optimization, a process is employed in which a series of random points is generated within the overlapping area defined by the flasher panel's vertices and the optical wafer's radius. Each point is then iteratively tested to determine if it lies within the polygon, the circle, neither, or both. The centroid of the points that were within both shapes is subsequently calculated. This process is repeated with new sets of random points centered on the previously found centroid until an optimal wafer placement is determined. Optimal wafer placement will maximize the usable optical area and performance in a panel. This process can then be applied for each unique panel in a flasher pattern to determine the best placement of each wafer. This process can then be utilized in other origami-based optical applications, leading to a broader impact in the field.
