Bacterial Separation by poly-Dopamine Coated Magnetic Nanoparticles

March 21, 2024 12:00 AM
Authors: Camille Bryner, Alyson Camacho, Bowen J Houser. Mentors: William G Pitt. Insitution: Brigham Young University. In an attempt to combat a growing number of nosocomial infections related to medical devices, many studies have investigated the effect of polydopamine (pDA) coated surfaces on biofilm formation and found them to have antibacterial and anti-adhesive properties. However, we discovered that pDA coated magnetic nanoparticles (MNPs) display strong attractive interactions with many, but not all, species of bacteria. Fe3O4 MNPs were prepared using sodium acetate, ethylene glycol, and iron (III) chloride hexahydrate solutions and characterized by a variety of methods. XRD data confirmed a magnetite pattern characteristic of Fe3O4, then TEM characterization of MNP samples showed successful pDA coating onto iron oxide particles. Bacterial capture efficiencies (CE) by pDA-MNPs for 8 strains of bacteria were measured by optical turbidity and plate counts. We have found that CE is a function of exposure time to and concentration of MNPS; thus some experiments were done with constant exposure time and variable MNP concentration and others were done at variable exposure times and constant MNP concentrations. Additionally, these pDA-MNPs exhibit extremely efficient adhesion to some bacteria such as Staphylococcus epidermidis (S. epidermidis) while being ineffective at capturing some strains of Esherichia coli (E. coli). We propose that such capture ability of pDA-coated MNPs can be employed for detection and identification of bacteria in hospitals and for food science quality control.

Bloom's and SOLO: A Comparison of Educational Taxonomies

March 21, 2024 12:00 AM
Authors: Spenser A Clark. Mentors: Acacia Overono. Insitution: Utah Valley University. It is not uncommon for a college student to see a list of learning objectives when skimming through a syllabus for a program or course. The goal of learning objectives is to set reasonable expectations for student learning and guide their study, as well as providing a framework for the development of teaching practices and assessment. Part of the inception of learning objectives as a means of organizing teaching and assessment in the classroom may be attributable to the Taxonomy of Educational Objectives, more commonly referred to as Bloom's Taxonomy. Another taxonomy similar to Bloom's, but much less well known, is the Structure of Observed Learning Outcome (SOLO) taxonomy. Bloom’s taxonomy organizes learning objectives into six categories: Remember, Understand, Apply, Analyze, Evaluate, and Create. The categories are structured as a cumulative hierarchy in which mastery of each level is assumed necessary for progressing to the next. The structure of Bloom’s is not derived from any specific learning theory, but a categorization of pre-existing learning objectives. Bloom’s therefore suffers from a lack of a strong theoretical foundation and may not accurately reflect how learning actually occurs. Additionally, although Bloom’s has been widely employed in the context of educational assessment, research has shown that it suffers from low interrater reliability and is inconsistent between educational contexts such as courses and topics. Unlike Bloom’s, SOLO is based upon Piaget’s Stage Development theory and categorizes learning into five distinct stages: Prestructural, Unistructural, Multistructrual, Relational, and Extended Abstract. SOLO does not suggest that learning is unidirectional or hierarchical. It also acknowledges internal cognitive processes rather than focusing solely on observable behaviors. Although very little research has investigated its reliability, it could be an attractive alternative to Bloom’s because it may more accurately reflect how learning occurs. The present work reviews the development and implementation of these two models and compares them.

Unlocking the Mechanism Behind Depotentiation: A Cellular Model for Forgetting

March 21, 2024 12:00 AM
Authors: Justin Webb. Mentors: Jeffrey Edwards. Insitution: Brigham Young University. Understanding the mechanisms underlying depotentiation in the context of previously induced long-term potentiation (LTP) is crucial for unraveling the processes of memory consolidation and forgetting. Our research is focused on synaptic plasticity in the hippocampus, the primary brain region responsible for mediating learning and memory. Using electrophysiology and neuropharmacological techniques, our goal is to elucidate the cellular mechanisms behind depotentiation, a reversal of the increase in postsynaptic response and overall synaptic strength characteristic of LTP. By doing this research, we hope to both fill existing gaps and resolve conflicting views about the processes and receptors involved in depotentiation. Experiments were performed on hippocampal brain slices of young mice. We induced LTP in hippocampal CA1 neurons using high-frequency electrical stimulation, and then elicited depotentiation in the same neurons via low-frequency electrical stimulation. This creates a cellular event analogous to learning and subsequently forgetting a new memory trace. Our preliminary findings show that depotentiation still occurs in the presence of MPEP, a metabotropic glutamate receptor (mGluR5) antagonist, suggesting that the depotentiation mechanism is independent of mGluR5. Additionally, because female rodent models have largely been ignored in prior electrophysiology experiments involving LTP and depotentiation, we investigated and observed gender-related differences, which show female mice exhibiting more pronounced depotentiation than their male counterparts. Building on these findings, our research will continue to identify gender-related differences in both juvenile and adolescent mice, as well as explore the role of NMDA receptors on depotentiation. We will also extend the temporal gap between LTP induction and depotentiation to explore the impact of early-phase versus late-phase LTP on subsequent depotentiation. This research aims to shed light on the intricate mechanisms of synaptic plasticity and its implications for learning, memory, and potential therapeutic modulation of these processes in the context of conditions like Alzheimer's disease, post-traumatic stress disorder (PTSD), and other disorders of learning and memory.

Bridging the Gaps: Geo-Coordinated Land Patent Linking for Socioeconomic Analysis

March 21, 2024 12:00 AM
Authors: Zachary Flynn, Britton Davis, Josh Nicholls, Bryson Mumford. Mentors: Joseph Price. Insitution: Brigham Young University. The United States has massive amounts of public data and land ownership stretching back to the early homesteading period of the American West. This data has been of limited use for economic research because it only includes the name of the ownership, thus making it impossible to study racial and gender differences in land on ownership. We develop an innovative method for linking individual land records to US census records. Our key innovation is that we start by linking individuals with unique names that we can make from land record to census record based on name and town. We then use the geo-coordinates in the land records and the proximity of households on the census sheets to link other individuals that have more common names. This two-step process allows us to link 36% of a sample of people in the land records in Colorado to a census record between 1880 and 1940. This new linked data will be a valuable resource for individuals doing research on the development of the American economy, and also people doing genealogical research.

Digging the Rabbit Hole: Jean Baudrillard and Mike Rothschild's "The Storm is Upon Us"

March 21, 2024 12:00 AM
Authors: Ezra Stein. Mentors: Nicole Dib. Insitution: Southern Utah University. In Simulacra and Simulation (1981), Jean Baudrillard lays out for stages through which a sign (an image or other representation of reality) becomes a simulacrum (a sign with no basis in reality). I argue that the followers of the Qanon conspiracy movement, as detailed in Mike Rothschild’s "The Storm is Upon Us" (2021), follow these four stages in their radicalization into the conspiracy. The first stage outlined by Baudrillard is when the image is a basic reflection of reality itself. We see this stage when Rothschild discusses how QAnon believers discuss the CIA. Adherents of QAnon will often point to the declassified MKULTRA documents released by the CIA for credibility, as this is something that was proven to have actually happened, the sign being a representation of actual reality. The second of Baudrillard’s stages is when a sign takes something from reality and twists and distorts it into something different than what it originally represented. An example of this in "The Storm is Upon Us" is seen in the way Q believers talk about adrenochrome, which is a real but harmless chemical compound, as an elixir of youth used by the elite. Stage three is when a sign claims to be based in reality but is actually based on nothing at all. The originator of QAnon, the man who goes by “Q,” fits within this stage. Rothschild lays out Q’s origins as an anonymous poster on the website 4chan who claimed to high-level military clearance. Q’s claims were supposedly based on real-life military intel, but were actually made up by an anonymous stranger on the internet. The fourth and final of Baudrillard’s stages is the simulacrum. This is when signs do not reflect anything in reality, but instead are based on other signs. The Storm is Upon Us shows that many QAnon beliefs, both major and minor, are based in pre-existing conspiracy theories like blood libel, flat earth, and global cabals that secretly control the world. Those who are completely indoctrinated into QAnon hold these beliefs that are based on other beliefs and are therefore existing in Baudrillard’s fourth stage of the precession of simulacra. My presentation will examine these four stages and demonstrate the overlap between this critical theory and the contemporary conspiracy movement that is taking up a considerable space in the American cultural imaginary.

Chronic obstructive pulmonary disorder remote patient monitoring using spirometry: a systematic review

March 21, 2024 12:00 AM
Authors: Joseph Nielson, Ben Schooley. Mentors: Ben Schooley. Insitution: Brigham Young University. Chronic obstructive pulmonary disorder (COPD) affects an estimated 30 million Americans and is the third leading cause of death worldwide. A recent effort to curb deaths and hospitalizations involves remote patient monitoring (RPM). Of all possible monitoring parameters, spirometry presents itself as potentially accurate and helpful, but the exact effect and its size remain to be described. A systematic literature review is being performed to describe the current state and future opportunities in RPM systems that use remote spirometry for COPD patients. Only studies that specifically mention the use remote spirometry for monitoring COPD patients were included. The databases PubMed, Web of Science, Scopus, and EBSCO were searched in July and August 2023. Studies are being synthesized by tabulating the study sizes and designs, technological parameters, and interesting findings. Twenty-nine studies have been included spanning feasibility and pilot studies as well as one randomized clinical trial. Remote spirometry for COPD patients has generally been shown to be feasible. Many studies present systems in early stages of development that have yet to be tested thoroughly in large trials. It may be necessary to involve remote spirometry in more large-scale trials soon. Future studies could confirm the degree to which spirometry adds helpful information for monitoring COPD patients.

Understanding the Effect of Printing Parameters and Prewetting on Binder Jetting Continuous Line Formation

March 21, 2024 12:00 AM
Authors: A. Kalani Brubaker. Mentors: Nathan Crane. Insitution: Brigham Young University. Binder Jetting is an exciting form of Additive Manufacturing in which a binding agent is selectively deposited on layers of powder to bind the powder together and create a 3D printed part. It is notable for its wide range of materials, energy efficiency, and built-in supports. Much research has been done on how to achieve desirable properties of binder-jetted parts and post-processing, but the fundamental principles of binder-powder interaction and the effects of changing printing parameters are still not fully understood. This research aims to increase that understanding. Each binder-jetted part begins by depositing individual binder droplets in a straight line, and the binder-powder droplets coalesce to form a single line. Adjacent lines are then printed to form a cross-section of the part, the next layer of powder is applied, and the process continues until a 3D part is printed. If the spacing between the droplets is too large or the inter-arrival time too short, the droplets form spheres on the surface of the powder (a phenomenon called balling), and a continuous line is not formed. This research determines how continuous line formation is affected by droplet spacing, inter-arrival time, and controlled misting of the powder bed prior to printing. To examine the effects of these parameters, lines were printed in dry and prewetted powder beds while varying the spacing and inter-arrival time between droplets. The beds were then examined using an optical microscope to determine whether continuous lines were formed. The results were recorded on a graph of inter-arrival time versus droplet spacing, and the “boundary line” for successful line formation was found for each bed. The results showed that the boundary on the prewetted data exhibited a different relationship than dry powder beds, suggesting that a different binder-powder principle may dominate after prewetting. The prewetting also shifted the boundary upwards, making it possible to form continuous lines at higher droplet spacings and shorter inter-arrival times. This increased ability to form continuous lines has the potential to significantly increase the throughput of binder-jetted parts.

Updated Third Generation Sequencing: Assembly Insights

March 21, 2024 12:00 AM
Authors: Danyon Gedris, Paul Frandsen. Mentors: Paul Frandsen. Insitution: Brigham Young University. Whole genome assembly has rapidly improved as third-generation sequencing technology like PacBio HiFi and Oxford Nanopore (ONT) have bridged the gaps of complex genomes by providing high-accuracy, long read data. The improvements in these technologies have resulted in long average read lengths (>15 kbp) and sequence quality scores above 99% (>Q20). They are particularly well-suited to assembling long, repetitive regions of the genome. Current assembly techniques combine reads with identical sequences to form longer, continuous sections. In repetitive regions, this process tends to condense the repeated sequences into one shorter read, instead of preserving the continuous nature of the repeats. Long reads avoid this issue by sequencing repeats together in one continuous read. Heavy chain fibroin (h-fibroin), the gene that encodes for the primary silk protein in Trichoptera and Lepidoptera, is long (often >20 kbp) and repetitive. Recent work showed that PacBio HiFi sequencing provided higher quality assemblies of h-fibroin when compared to the last generation of ONT pores (R9.4.1) and chemistry despite having a shorter average read length. Recent advances in ONT chemistry and nanopores (R10.4.1) have led to higher quality scores, perhaps allowing successful assembly of this gene region. To better understand the advances in ONT sequencing and its ability to provide high-quality, continuous genome assemblies of complex organisms, we assess the quality of assemblies of the h-fibroin silk gene for the Trichoptera species, Arctopsyche grandis and Parapsyche elsis, using the newest ONT chemistry.

Guiding Souls, Shaping Towns: Clergy's influence on Population Dynamics

March 21, 2024 12:00 AM
Authors: Seth Cannon. Mentors: Joe Price. Insitution: Brigham Young University. We use the occupation strings in the full-count US census files from 1880-1940 to create a new dataset of everyone during this time period that listed their occupation as a clergy (or related term). We use this data to identify the number of clergy located in each town in the United States in each census year. We find that towns with at least one person that identifies as clergy in the census record experience 5.4% greater population growth by the next census compared to towns without any clergy. This result is robust to various ways to control for the population and other characteristics of the town. We also focus on just the set of towns that had only one person in the census who identified as clergy. When we restrict the dataset to these towns, we find that the towns for whom that single clergy member died before the next census experienced an average population loss of 2.8%, while towns that didn’t have their clergy die experienced a population growth of 12.5%. These results highlight the ways in which access to local religious resources can help promote economic growth in small communities.

Musical Manipulation: Controlling Memory And Emotions Through Auditory Processing

March 21, 2024 12:00 AM
Authors: Kaerli Ringle. Mentors: Johnathan Chidester. Insitution: Southern Utah University. This presentation will discuss the way that music affects memory retention, memory recall, and how it can influence the memory of moments, moods, and emotions. The Public Broadcasting System produced an educational video about how listening to music boosts learning and memory. Research from Harvard noted that while neuro-imaging a patient, singing will help a patient during recovery with a brain injury or a stroke. This results because the left-brain region is majorly responsible for our speech function. Researchers also noted that because singing takes place in the right hemisphere, recovering stroke, Dementia and Alzheimer’s patients are able to regain their speech through singing and eventually being able to transition back into speaking. Having knowledge of how music affects the brain can help build great study habits and empower people to retain new information, recall old information, and have influence over their and other people’s emotions. This is important because music is around us all of the time, whether it is walking through the grocery store or playing through earbuds while studying, and if it has such power to influence these things, then why not use it to the fullest of its potential?

Constant pressure untethered soft robotics: an adaptable solution to the limitations of soft robots

March 21, 2024 12:00 AM
Authors: James Wade, Chris Paul. Mentors: Nathan Usevitch. Insitution: Brigham Young University. Soft Robotics offer significant advantages when completing certain tasks compared to other robots and methods. Compliance, adaptability, and energy efficiency are a few of the major advantages. On the moon, where safety, volume and versatility are of high importance, soft robotics may find an innovative niche. NASA’s BIG Idea Challenge for 2024 incentivizes creating new innovative soft robot designs. Our research group is building our facility mentor, Nathan Usevitch’s, work at Stanford University. Doctor Usevitch and his cohort developed an octahedral, inflated robot composed of multiple tubes folded into triangular shapes in a truss-like structure. Each triangle consisted of a long inflatable tube and 3 motorized modules at the nodes of the triangle. The motorized nodes (consisting of a DC motor and rollers) roll along the length of the tube, lengthening one edge of the triangle while shortening the other. By attaching multiple triangles to each other in geometric shapes, flexible structures are created that can adapt their shape to the desired need. Because this system has a constant inflated volume, no external air compressor is necessary, allowing for untethered movement. The bulk of the mechanical work is performed by electric motors, providing a higher energy efficiency than a system of repeated inflation. Furthermore, this design is compactly stored when deflated, optimal for transport into space.To build on this design and optimize it for use on the moon, our research group will make the following changes and improvements:- Developing the physical prototype. This will enable robust and dynamic movement and the support of large loads- Develop a simulation tool that allows us to explore different configurations of the robot for different tasks- Develop a joint system that allows an astronaut to quickly reconfigure the triangles into different structures based on the required task - Develop a control approach that accounts for the underdamped dynamics of large inflatable structuresThrough our research, we hope to expand the possibilities of soft robotics. We are synthesizing the advantages of traditional robotics (robustness, untethered motion) with the unique strengths of soft robotics (flexibility, adaptability, cost efficiency).

Temporal Decay of Memory Discrimination: Investigating Mnemonic Similarity Task with Extended Delays

March 21, 2024 12:00 AM
Authors: Alexandra Osmond, Samantha Stabler, Sara Knowlton, Sam Chipman, Brock Kirwan. Mentors: Brock Kirwan. Insitution: Brigham Young University. Memory discrimination refers to the ability to distinguish between different memories or experiences based on their unique characteristics or details. The Mnemonic Similarity Task (MST) is a variant of a recognition memory task that assesses memory discrimination by asking participants to encode a series of objects in long-term memory and later discriminate between targets (repeated items), lures (similar but not exactly the same as previously seen items), and foils (novel items). The similarity of targets and lures is systematically varied resulting in five similarity levels (L1-L5). The goal of our research was to determine if individuals retain memory discrimination abilities after different periods of time exceeding 12 hours. Study recruitment was done on Brigham Young University campus for 18-25 year olds with no known neurological conditions (ADHD, major depression etc.). Thirty participants were tested in each group and they were asked to complete an immediate test. They were then asked to return to the lab for a second test after a 1-day, 3-day, or 1-week delay.Our results showed that the 1-week delay of the MST eradicated an individual's ability to discriminate between the lures of varying similarity. At a 1-day delay, individuals did lose some memory discrimination ability, but were still able to recognize the more distinct lures.

Using Automated Web Scraping to Document Variation in Sodium Content of Common School Meal Entrees

March 21, 2024 12:00 AM
Authors: Aaron Brown, Kimball Jardine, Nathan Schill, Courtney Webb, Joanne Guthrie. Mentors: Joseph Price. Insitution: Brigham Young University. Background: Many school districts consider meeting the National School Lunch Program (NSLP) sodium standards challenging. USDA national survey data indicate that in School Year 2014-15, 28% of lunch menus did not meet the standard. Entrees contributed the largest share of sodium, making their sodium content especially important.Objective: Assess variation in sodium content of popular entrees across a large national sample of school districts.Study Design, Settings, Participants: School menu data including item sodium content were obtained from 1149 school districts using an automated web scraping program.Measurable Outcome/Analysis: Menus were web scraped monthly between August 2022 and January 2023. Variation in sodium content of two popular entrees−pizza and chicken nuggets−was analyzed, with average sodium content compared across different regions in the US and also based on the per-pupil spending of the district.Results: There is statistically significant variation in entree sodium content between regions, with the South having the highest average level of sodium. The average sodium level is also highest in the districts that have the lowest per-pupil spending.Conclusion: Sodium content of popular entrees exhibits significant variation across school districts. This highlights the fact that districts could reduce the amount of sodium in their lunch entrees while still offering the popular entrees they serve.

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.

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.

Influence of Childhood Levels of Self Control on Adolescent Sleep Outcomes

March 21, 2024 12:00 AM
Authors: Jacalyn Richey, Hayley Pierce. Mentors: Hayley Pierce. Insitution: Brigham Young University. Good sleep habits and effective self-control are important components of successful functioning. Unfortunately, chronic sleep loss is a common concern in adolescence as both their autonomy and demands on their time increase. This loss of sleep impacts neural and physical development and is connected with increased mental illness, delinquency, and academic difficulties. Self-control may aid in the prioritization of sleep by curbing impulsive desires and improving decision making around adhering to bedtimes. This study drew on data from the Future of Families and Childhood Wellbeing Study (FFCWS) measuring self-control at age 9 and sleep outcomes at age 15 (N = 3,444; 48.7% female; 49% Non-Hispanic Black). Multivariable analyses indicated that self-control showed statistically significant relationships with social jetlag, falling asleep, and having a regular bedtime after controlling for several relational and economic factors. Improving childhood self-control habits and skills through modeling and instruction may lead to increased positive sleep outcomes, which may increase healthy development in adolescence and beyond.

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.

Investigating the Effectiveness of Incentivized Efficient Watering Practices in 5 Western States with Focus on Utah

March 21, 2024 12:00 AM
Authors: Ashley Swensen, Ruth Kerry. Mentors: Ruth Kerry. Insitution: Brigham Young University. The American West has been experiencing severe drought for over 20 years with changes in climate. Also, the population in certain states has greatly increased putting increasing pressure on the limited fresh water supply. While the agricultural sector is the biggest consumer of freshwater, much is also used to irrigate turfgrass lawns in urban residential areas. The EPA has estimated that about 50% of household irrigation water is wasted by temporal and spatial misapplications. Temporal misapplications can be reduced by using smart sprinkler controllers that take into account recent weather when scheduling irrigation timing. This research investigates people’s willingness to implement more efficient watering practices with and without incentives. It also investigates how an average water bill for a quarter acre lot varies between states and between cities within 5 states in the semi-arid west (AZ, CO, ID, NV, UT). Following comparison of average water bills between states and cities, the potential savings from taking advantage of water saving incentives offered by cities is investigated. The research found differences between the genders and aridity zones in terms of the types of incentive that are favored and likelihood of utilizing methods to improve irrigation efficiency. Water bills were the highest in AZ and lowest in ID and UT. The low water bills in ID are likely associated with the greater prevalence of agriculture in that state than the others studied. Most UT cities had incentives for Smart Sprinkler controllers or to xeriscape. However, in other states several cities did not have incentives for installing Smart Sprinkler controllers. We conclude by trying to assess whether incentives or disincentives are more effective at reducing water use by residential customers.

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 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.

Relationship Between Income and Lifespan Using Historical Data

March 21, 2024 12:00 AM
Authors: Joseph Price, Britton Davis, Alexander Jenks. Mentors: Joseph Price. Insitution: Brigham Young University. Modern data show a strong positive relationship between community-level average income and life expectancy in the United States. We compile a dataset including place of residence, lifespan, and a proxy for income for 27 million unique individuals from the 1900-1940 censuses. In contrast to the pattern in modern data, we actually find that individuals living in an enumeration district with the top quartile of our proxy for income experienced shorter lifespans than those living in the bottom quartile. We show that this negative relationship was largest in the 1900 census and slowly shrank over the next four decades showing how this negative relationship evolved to the positive relationship we see today.

The Influence of Problematic Media Use on Language Development

March 21, 2024 12:00 AM
Authors: Allison Weston, Summer Snow, Sophia James. Mentors: Sarah Coyne. Insitution: Brigham Young University. As childrens’ minds develop, so does their language, however, the effect of media on language has yet to be firmly established. Our study searched for the effect of screen time on language development, and whether problematic media use (PMU) was a factor in normal or late development of language. Data was gathered from a sample (n=265) of 4 year old children using simple regression for problematic media use predicting language development while controlling for screen time. Although the correlation between screen time and language development has been studied, there is a gap in the literature regarding how PMU may relate to language development.

Sodium Reduction Policy Response

March 21, 2024 12:00 AM
Authors: Jacob Hutchings, Harrison Li. Mentors: Joe Price. Insitution: Brigham Young University. We examine the effectiveness of federal school nutrition policies and regulations; specifically, the recent transitional targets for sodium reduction announced in 2021. We performed web-scraping to gather over 5 million observations representing every U.S. state and over 2000 school districts and then constructed a weekly average of sodium served in school lunches by district. Using this data, we apply OLS regression with district fixed effects and find that the policy caused a significant, one-time reduction in weekly average sodium of approximately 220 mg. We further explore this result by looking at heterogeneous responses to the policy by political partisanship. We find that there is a significant, partisan response to the transitional targets. Lastly, we consider an adverse effect of sodium reduction by looking at potential sodium substitutes in school lunches. Contrary to expectations, our data shows a statistically significant correlation between decreased sodium levels and decreased sugar levels. To conclude, sodium reduction policies reduce sodium and other harmful nutrients but may be less effective across party lines.

The Relationship Between Social Media and Body Image

March 21, 2024 12:00 AM
Authors: Fiona Fox, Catherine Schumann, Cameron Monson. Mentors: Sarah Coyne. Insitution: Brigham Young University. Most often, research has looked at the negative effects of social media on mental health. The purpose of this study is to understand the interactions between social media usage and body image, and if there are any ways that social media has a positive impact on body image. This study surveyed children and youth ages 7-17 to gain insight on their social media use and different aspects of mental health. Social media preoccupation and mindfulness were both significantly correlated with body esteem, and a slightly significant correlation was found between positive social media use and body esteem. These findings suggest that mindfulness around social media usage can help mitigate the negative impact on body esteem that many youth experience. Parents can use these findings to have conversations with their children and teenagers about being mindful with social media use and avoiding preoccupation with it.

Experience impact and the influence of novelty, social connection, and positive emotions on tourist experiences

March 21, 2024 12:00 AM
Authors: Braden Bringhurst, Michael Ray, Megan Barbier, Ellie Smith. Mentors: Peter Ward. Insitution: Brigham Young University. In travel, the interplay of social connection and novelty profoundly shapes the impact of peoples' experiences. This study examines novelty, positive emotions, social connection, and the impact of the experience on participants through the lens of the Self-Expansion Theory. Novelty is defined as the process of experiencing or encountering something different to the objects regularly encountered in everyday life. Social connection is defined as the affective and cognitive perception of interrelatedness within social groups, encompassing emotional responses like feeling understood and valued. Positive emotion is defined as pleasant multicomponent response tendencies, including joy, interest, contentment, pride, and love. Experience impact is defined using the experience typology. This typology starts with prosaic experiences or ordinary parts of life. The next progression is memorable experiences which introduce felt emotions into the experience. The next stage is meaningful which introduces discovery as well as emotions into the experience. The final stage is transformational which introduces a desire, or actual personal change happening to the experiencer as well as emotions and discovery. To measure the various stages of the experience typology framework, we use the Experience Impact Scale to identify the personal impact of a tourist experience. These various constructs are explored through the perspective of the Self-Expansion Theory which states that people seek to expand their potential efficacy, perspectives, and sense of self through the development of relationships. This study utilizes this theory by looking into novelty’s effect on the impact of an experience through the lens of Self-Expansion Theory with respect to social connection and positive emotions as mediating factors. The data were analyzed using structural equation modeling in AMOS v 28. Models were gradually expanded on, starting with the initial relationship between subjective novelty and experience impact. Later, a mediating model was considered that incorporated subjective connection and positive emotions as mediating effects on experience impact. The model examining the relationship between subjective novelty and experience impact as mediated by subjective connection and positive emotions had an acceptable model fit. The significant factors that contributed to the model were subjective novelty which had a standardized regression weight of .264, subjective connection which had a standardized regression weight of .222, and positive emotions which had a standardized regression weight of .256. The model explained 16% of the variance within experience impact. This study demonstrates that novelty influences social connection which influences positive emotion which positively impacts the tourist experience. People designing experiences should create a novel experience for the experiencer that evokes positive emotions and facilitates social connection. Future research could explore the relationship between the novelty of location and activities associated with tourist participation and the impact on the experience.

The "fly"-logeny of Drosophila Chromosome Evolution

March 21, 2024 12:00 AM
Authors: Audrey French, Carl E Hjelmen. Mentors: Carl E Hjelmen. Insitution: Utah Valley University. Chromosome numbers are often one of the first pieces of genetic information we collect about the genome of an organism. These chromosome numbers vary widely across the tree of life and will change due to fission and fusion events, where the number increases or decreases, respectively (Blackmon and Demuth 2015, Perkins et al. 2019, Sylvester et al. 2020, Morelli et al. 2022). As the Drosophila species group has been a model for more than 100 years, there is a plethora of information on their karyotypes, including number, chromosome shapes, and sex chromosome systems. The shapes of chromosomes vary and can be described as metacentric (v), submetacentric (j), telocentric (rod), and small and heterochromatic (dot). In the Drosophila genus, sex chromosome systems can be neo-sex, XY, and X0. The numerous species of Drosophila can be compiled into the major subgenera of Drosophila and Sophophora, which have diverged for around 40-65 million years. The karyotype data of the Drosophila genus has been compiled into an open-source database. I am using this database to find the rates of chromosome number change in the Drosophila genus. This analysis is done through the chromePlus package in R (Blackmon et al., 2019) which will perform a comparative phylogenetic analysis, and a phylogeny of 152 species in the Drosophila genus (Hjelmen et al., 2019). Using these available tools, I can compare rates of fusion and fission between sex chromosome systems and subgenera. This could expand the knowledge on evolution of chromosomes and genomes.

The Newborn Behavioral Observation (NBO) and Its Impact on Early Relationships, Postpartum Depression, and Infant Outcomes

March 21, 2024 12:00 AM
Authors: Tara Caplin, Tiffanee Suhaka, Maria Balaceanu, Peg Bird, Dannelle Larsen-Rife. Mentors: Dannelle Larsen-Rife. Insitution: Utah Tech University. Early parent-child interactions have a profound impact on the developing brain, influencing lifelong emotional and social well-being. This review evaluates the Newborn Behavioral Observation (NBO), a relationship-based neurobehavioral approach for families and infants three months old and younger. The NBO supports newborns, caregiver’s, and families by providing individualized information on their infants' behavior and competencies. It facilitates communication and intersubjectivity between infants and caregivers during a critical developmental period, while reducing maternal postpartum depression (PPD). Research on the association between the NBO, PPD, and infant neurodevelopment is reviewed and evaluated in high-risk populations. Although evidence supports approaches like the NBO, they are not yet standard in early intervention due to clinicians' lack of training in infant mental health. The NBO is a foundational tool for cultivating positive early relationships with beneficial implications for clinician standard care of newborns and families. Keywords: Newborn Behavioral Observation (NBO), early relationships, postpartum depression (PPD), infant development, relationship-based, early intervention.

When One is Loved: Attachment Security and Relationship Quality

March 21, 2024 12:00 AM
Authors: Maria Balaceanu, Dannelle Larsen-Rife, Tara Caplin, Peg Bird, Grace Carsey, Tiffanee Suhaka. Mentors: Dannelle Larsen-Rife. Insitution: Utah Tech University. Attachment theory provides a framework for understanding how early experiences with caregivers influence individuals' emotional and relational development throughout their lives. In addition to understanding how an individual interacts with close others, attachment predicts relationship satisfaction (Gardner et al., 2020). Individuals with secure attachments demonstrate greater adaptability in coping and regulating their emotions, leading to improved socio-emotional well-being. In contrast, those with insecure attachment styles tend to encounter difficulties in socio-emotional adjustment (Gardner et al., 2020). This study will examine how insecure attachment is associated with romantic relationship dissatisfaction, specifically those lasting five years or longer. We focus exclusively on romantic relationships lasting five years or more because in adult relationships, each partner serves as an attachment figure for the other (Diamond et al., 2008). Therefore, spouses have the potential to increase each other's attachment security. This means an initially insecure individual can develop earned secure attachment with their spouse's support. Approximately 300 diverse participants over the age of 18 will be recruited for the study. The Relationship Structures Questionnaire (ECR-RS; Fraley et al., 2011) will assess insecure attachment. The Relationship Assessment Scale (Hendrick, 1988) will assess satisfaction. It is expected insecure attachment will be correlated with lower relationship satisfaction with a romantic partner of five years or longer. Results of the analyses will be presented.

Visualizing the impact of the Arab Spring on Women Empowerment in the Middle East region.

March 21, 2024 12:00 AM
Authors: Mary Harris. Mentors: Joshua Gubler. Insitution: Brigham Young University. Middle Eastern governments typically score at or near the bottom of indices measuring women’s rights and political participation. The Middle East also contains a large saturation of authoritarian regimes. The Arab Spring challenged these regimes' structures and included vast female participation, but there is little existing research to understand the Spring's impact on women's participation and empowerment in the region. This study aims to add to the research by gathering data from the Arab Barometer to plot public opinion surveys before, during, and after the Arab Spring for a variety of countries in the Middle East and North Africa region. A difference on difference t-test shows the statistical difference of change in opinion before and during the Arab Spring. Twenty semi-structured interviews (conducted in Jordan in 2022) supplemented the quantitative analysis attempting to show the causation between the Arab Spring and the growth in public opinion toward women's empowerment. These are conducted under the hypothesis that: Women’s participation in the Arab Spring improved public opinion towards women’s empowerment in the region. The quantitative analysis illustrates a correlation between the Arab Spring and opinions of women's empowerment, but the shifts of opinions are both negative and positive. The data suggests that the negative impact is connected with the second half of the Arab Spring when the governments were subject to more instability. The interview's results differ from the hypothesis and illustrate little connection between the Arab Spring and public opinion of women's empowerment. These results are affected by the lack of movement in Jordan during the Arab Spring. More research is needed to understand the causation of such a phenomenon in other countries.

IBD Support: Mental Health Matters

March 21, 2024 12:00 AM
Authors: Kacey Rowe, Rachel Arocho, Allison Ensign. Mentors: Rachel Arocho, Allison Ensign. Insitution: Utah Valley University. Mental health amongst IBD patients is often overlooked and forgotten when they are dealing with their personal physical symptoms. There is little research on the benefits of social support for IBD patients. In online forums, it appears some IBD patients report feeling depressed and having negative thoughts about living life on a day-to-day basis. Indeed, prior research has found associations between IBD and mental health; for example, one study found that 17.3% of IBD patients had lifetime suicidal ideation, which is much higher than the general population at a 4.0% rate (Xiong et al., 2022). Another study did physical and mental exams and found on average, people with higher depression symptoms were six times more likely to have their disease be more active (Marrie et al., 2021, para. 16). Due to the high rate of depression, it would be beneficial to design a website to track symptoms and create online forums giving people the opportunity to connect with peers who have IBD. IBD can drastically affect a person’s life, even in a mild case. According to the CDC, IBD is estimated to affect 3 million US adults, a little over 1% of all Americans (Xu et al, 2018). Few people in the 1% category who struggle with IBD have connected online with others who are experiencing the same autoimmune disease. Although prior research has identified the association between physical IBD symptoms and mental health, little has been proposed to help these patients. Our goal is to create a form of social support for people who have been diagnosed with IBD. For 30 days, we will take 20 participants and have them record their symptoms and thoughts through quantitative and qualitative data. To do this, the participants will be asked to use a website which we have created from scratch. They will be using the Patient Health Questionnaire-9 (PHQ-9) and the Short Inflammatory Bowel Disease Questionnaire (SIBDQ). The PHQ-9 will be used to check in on mental health, while the SIBDQ will focus on the physical symptoms of IBD. Each week, they will participate in forums on the website, which will allow them to connect online and anonymously with others who share their experiences. At the start of the month, daily throughout the study, and at the end of the month, participants will report on their health symptoms through a combination of the measures named above and short tracker questions. (Note: Project is still under IRB approval, we aim to start participants by the end of the year.)

Elucidating the Role of TOX on Melanoma Cell Migration and Invasion

March 21, 2024 12:00 AM
Authors: Allison Stevens, Gennie Parkman. Mentors: Gennie Parkman. Insitution: Weber State University. The principal genes that are responsible for the conversion of benign nevi, or pigmented lesions, to cancerous melanomas have been discovered and validated. However, we are still identifying the additional genetic alterations that are responsible for the migration and invasion of melanoma cells and ultimately metastasis of these melanomas as that is where treatment needs remain. (Davies, et al., 2002)One gene that has been identified to potentially play a role in the metastasis of melanoma is thymocyte selection associated high mobility group box, or TOX. Based on one study, the levels of TOX gene expression were found to be elevated in melanoma brain metastases versus extracranial metastases (Bierman et al., 2022). These findings have led us to hypothesize that TOX plays a role in the migration and invasion of melanoma into the brain. Preliminary work has been completed to clone our gene of interest, TOX, into an expression vector and transduce mammalian melanoma cells to evaluate their effects on melanoma cell rate growth and migration. These experiments will identify the effect of TOX on the initiation and progression of melanoma cells through in vitro melanoma cell culture and experimentation before potentially progressing to well-validated mouse models of melanoma.

Transcriptome analysis to study the effects of drought in tomato

March 21, 2024 12:00 AM
Authors: Aubrilin Johnson. Mentors: Yu Ya Liang. Insitution: Utah Valley University. Drought stress negatively affects the growth, survival, and production of crops. Developing drought-tolerant cultivars is an important strategy for maintaining crop yields under undesirable water conditions. Tomatoes are an important crop both grown worldwide and here in Utah. Improving drought tolerance in tomato plants can increase yearly yields and reduce the amount of crops lost during the periodic droughts that Utah has. A way to develop drought-tolerant tomatoes may be through identifying and utilizing genes that enhance survival and growth rates under stressful water conditions. In this study, we will use two varieties of tomato, including drought-tolerant wild species, and susceptible commercial varieties. According to previous studies, drought during late the vegetative stage will significantly reduce the yield, therefore this study will focus on that. Using RNA-seq to find the difference in gene expression between the control and drought groups. Identifying differences will facilitate in finding candidate genes that may have a potential role in drought resistance. Then take the top cultivar and find the specific drought-resistant gene, which can then be used by Utah tomato growers to yield more resistant crops.

Using Pair Blocking to Better Identify Unique Matches

March 21, 2024 12:00 AM
Authors: Erica Webb, Joseph Price. Mentors: Joseph Price. Insitution: Brigham Young University. Blocking is a strategy used in machine learning to reduce the number of comparisons that need to be considered. In this paper, we develop a blocking strategy based on the characteristics of two people in the same household. We apply this pair blocking approach to link US census records and show that it dramatically reduces the number of possible matches to consider and can directly identify millions of unique matches at the blocking step. We apply our method to linking records for a few groups that have been harder to link using previous methods, including inter-racial couples and German-born Americans. Both of these are groups that have changed how they report aspects of their identity (race of birthplace) over time. Our approach allows us to dramatically increase the match rates for these couples across adjacent census years.

Waking up Rubus: germination protocols for thimbleberry

March 21, 2024 12:00 AM
Authors: Grace McFarlane. Mentors: Michael Rotter. Insitution: Utah Valley University. Thimbleberry (Rubus parviflorus) is a native shrub to North America, and can be an important component in restoring native plant communities. Members of this genus tend to have physically hard seeds and low germination rates, resulting in a lack of ability to grow this plant by seeds and increasing genetic diversity in restoration sites. We investigated six different methods in order to produce higher germination rates, tracking them over time. Using seeds from three different populations we planted these thimbleberry seeds in groups of 50 for each germination method, monitoring the rates of growth and the success rate percent. These methods included standard planting as our control, cold stratification using a fridge, scarification with sandpaper, hot water bath by boiling the seeds, acid bath with sulfuric acid, and a room temperature soak in water overnight. Our goal is to identify a standard procedure for high germination rates and success.

Positive Emotion and Suicidal Tendencies: A study of daily emotional regulation use in autistic and socially anxious groups

March 21, 2024 12:00 AM
Authors: . Mentors: Jared Nielsen. Insitution: Brigham Young University. Objective: This study examines the role of positive reframing as a strategy to mitigate suicidality and enhance positive emotions. Background: Emotional regulation difficulties have been identified in numerous psychiatric populations, potentially leading to stress, incarceration, and tragically, suicide. Amidst the rising rates of suicidality among at-risk populations, this study aims to investigate the pivotal behavioral factors influencing suicidal thoughts and actions in autistic and socially anxious populations. Methods: Our investigation employed a longitudinal ecological momentary assessment study to explore the impact of various emotional regulation skills on positive emotion, negative emotion, and suicidality. We recruited 95 participants, 72 of which met criteria for inclusion, to answer daily surveys administered through a smartphone app that tracked emotional regulation use, positive emotions, negative emotions, and suicidal tendencies over time. Results: Our results indicate that for the social anxiety group, enjoying the moment significantly affects positive emotions (E=2.14, p<.05), but this effect is not observed in the autism group. Furthermore, both groups demonstrated that accepting feelings (E=4.40, p<.001; E=2.63, p<.01) and acknowledging that feelings don’t last (E=1.69, p<.05; E=3.13, p<.001) significantly increased daily positive emotions. Conversely, hiding feelings significantly decreased daily positive emotions in the social anxiety group (E=-1.76, p<.05). Self-blame increased negative emotions in both groups by, on average, four points. Regarding the reduction of daily average suicide composite scores, accepting feelings emerged as a significant factor for both groups (E=-1.88, p<.01; E=-2.15, p<.001). On the other hand, using self-blame significantly increased average suicide composite scores for social anxiety, mirroring its effect on negative emotions (E=1.42, p<.01). Conclusion: Positively reframing one's emotions is associated with increased daily positive feelings and reduced daily suicidal tendencies. This research sheds light on the complex interplay between emotional regulation strategies and their impact on mental health and emotions in these at-risk populations.

Does an Insecure Attachment (Anxious and/or Avoidant) to God and the Contextual Perception of God (Belief that God’s Character is Consistent with what the Bible says about God’s Character) Affect Levels of Distress?

March 21, 2024 12:00 AM
Authors: Eliya Rodrigues. Mentors: Grant Corser. Insitution: Southern Utah University. Does an Insecure Attachment (Anxious and/or Avoidant) to God and the Contextual Perception of God (Belief that God’s Character is Consistent with what the Bible says about God’s Character) Affect Levels of Distress? People who identify as spiritual/religious that have an attachment to God are associated with having lower levels of depression, while people that have an insecure attachment to God, and a judgmental perception of God have higher rates of depression (Bonhag, R., & Upenieks, L. (2021). The purpose of this research is to investigate if there is a relationship between the style of attachment to God, the contextual perception of God, and levels of distress. The perception element of this research question will be analyzed through the contextual perception of God as defined in appendix D. Data will be collected using Qualtrics and will have three different scales (Attachment to God Inventory, Kessler Psychological Distress Scale, and Belief of the Character of God Through a Contextual Perspective) consisting of qualitative questions and a few open-ended questions regarding the subject. Data will be analyzed through correlational statistics on SPSS. It is hypothesized that a low score of an insecure attachment to God and regarding scripture in the bible as truth for God's character will decrease levels of distress. This research needs to be conducted because it could be a way for people to evaluate their own attachment to God; the way people view God could lead them to understanding that if part of the distress they experience in their lives is from their own perception and/or attachment to God.

Finite Element Simulation of Microfluidic Chips

March 21, 2024 12:00 AM
Authors: Robert Macdonald. Mentors: Troy Munro. Insitution: Brigham Young University. Due to the recent developments in the precision of small scale 3-D printing, the use of complex multi-dimensional heating geometries is now very feasible in microfluidics. Small channels can be filled with liquid metal and can become a heat source by passing an electrical current through the liquid metal. There is a desire for the creation of isothermal areas within microfluidic chips for processes such as polymerase chain reaction and melt curve analysis of DNA to detect mutations. One difficulty of designing isothermal areas in microfluidics is the complexity of the geometries involved and the precision needed to be useful. These two problems were addressed by using a finite element software COMSOL to simulate the microfluidic chip to aid in design iteration. Quick evaluation of the performance of different heating geometries in COMSOL allows for faster evolution of our design. Using these principles, a novel microfluidic chip design was developed with a simulated isothermal volume of 5 microliters and a temperature variation of <0.1 degrees Celsius.

Stereotactic Body Radiation Therapy Success – What Role Does Connexin-43 Distribution Play?

March 21, 2024 12:00 AM
Authors: Tanner Frahm, Eugene Kwan, Ravi Ranjan. Mentors: Ravi Ranjan. Insitution: University of Utah. Introduction:Stereotactic body radiation therapy (SBRT) is a non-invasive treatment for ventricular tachycardia (VT) that acts as a promising alternative to the current gold-standard treatment, catheter ablation. Preliminary clinical successes indicate the promise of SBRT while subsequent animal studies suggest that the mechanism of SBRT is novel and unknown. We propose SBRT may alter Connexin-43 (Cx43) gap-junction distribution in cardiac myocyte walls, affecting electrical conduction and reducing VT episodes. A large animal model was used to evaluate Cx43 changes post-SBRT, aiming to elucidate its mechanism of action. Understanding this could expand SBRT's use in arrhythmia management and explore myocyte reprogramming.Methods:A large animal model (n=3) underwent cardiac SBRT on portions of their heart. Each animal provided control, untreated tissue, and treated tissues. Post-treatment, the hearts were excised, perfused, and preserved. Transmural sections were processed for histological and confocal microscopy analyses to assess scarring and Cx43 distribution. An algorithm for semi-automatic myocyte segmentation and Cx43 distribution analysis was developed and used. Two-sample student t-tests were conducted to compare Cx43 distribution between treated and control regions. All image and statistical analysis were performed in MATLAB.Results/Discussion:Preliminary results for the three preliminary animals indicate that treated regions of the myocardium had statistically significant differences in Cx43 distribution (p-values < 0.05). Treated values (mean  standard deviation) were 48%  25%, 62%  26%, and 64%  17% of the distribution of Cx43 on the longitudinal ends while the untreated were 42%  30%, 44%  25% and 26% 16%. The proportion of Cx43 distributed along the longitudinal axis (the short ends of the myocyte) increased in all three animals. The results build on the findings of previous animal studies which suggested that the scarring like ablation was not the mechanism, but that Cx43 or other cellular components could be changing in response to therapy. Conclusions:The findings support the hypothesis that Cx43 distribution changes in response to SBRT indicating that the radiation could be inducing remodeling at the cellular level. Evidence of non-invasive cardiac reprogramming provides basic science credence to the preliminary and ongoing clinical studies evaluating the treatment in patients. The findings further inform and motivate more animal studies and analysis of changes to other cellular components.

Attitudes Regarding Gender and Sexuality Scale

March 21, 2024 12:00 AM
Authors: Viridian Hellebore, Isabella Rodriguez, Stockton Palmer, Sim Perry, Justine Padilla. Mentors: Kirsten L Graham. Insitution: Southern Utah University. The examination of attitudes towards the LGBTQ+ community presents a newly found psychological concept that plays an important role in fostering social inclusion, reducing discrimination, and promoting a more accepting society. The purpose of our study is to create a measure that will assess a person's general attitudes towards the LGBTQ+ community. In the current social and political climate of the US, there are a multitude of differing thoughts, opinions, and feelings regarding the community- some that are positive, and some that are negative. Current and past research generally only focus on sexuality, requiring the need for a scale that includes all members of the LGBTQ+ community. Such past works include Attitudes Toward Lesbians and Gays Scale (Herek 1988) as well as the Index of Attitudes Toward Homosexuals (Hudson & Ricketts 1980). The Attitudes regarding Gender and Sexuality Scale (AGSS) was created to provide a single scale that will measure a variety of attitudes towards the LGBTQ+ community. The AGSS covers fear, understanding, and tolerance- related aspects of these attitudes. Before releasing the scale to the general public, the scale was given to five subjects to assess for face validity. Participants will be recruited from MTurk and social media, and will be asked to respond to 21 questions that envelop the above aspects of attitudes. The participants will answer the “Gender/Sex Diversity Scale'' (Sudson, 2022) alongside AGSS to test for construct validity. The participants will also be asked to answer two scales that are measuring different constructs to test for discriminant validity. Once all of the data has been collected a confirmatory factor analysis will be ran. To test for reliability, we will be using the internal consistency method. For this we will be testing for Cronbach’s coefficient alpha since our scale using a 7-point Likert scale. We hypothesize that AGSS will be able to measure both negative and positive attitudes that are directed towards the LGBTQ+ community. With these results further research could be conducted to evaluate the effectiveness of anti-discrimination laws, the reasoning behind these attitudes, and how the attitudes affect the wellbeing of the LGBTQ+ community.

A look at Suicidality Among Various Demographics at Southern Utah University

March 21, 2024 12:00 AM
Authors: Maggie Smith, Bryan L Koenig. Mentors: Bryan L Koenig. Insitution: Southern Utah University. Nationwide, Utah ranks 14th for suicide rates (CDC, 2021). To help prevent suicide, understanding suicidal ideation differences among certain populations such as sexual, ethnic, and racial minorities is important. One study found that LGBTQ+ individuals are three times more likely than non-LGBTQ+ individuals to attempt suicide at some point in their lives (di Giacomo et al. 2018). Religious background has also been connected to suicidality. Sterling and colleagues (2002) discovered that active LDS males aged 15–34 years have a lower risk of suicide compared with both less active LDS members and non-LDS individuals. Whereas some studies have samples of diverse ages and locations, research on suicidality among college students specifically in Utah is lacking. The purpose of the present research is to assess how demographic variables such as religious identity, biological sex, sexual orientation, gender identity, and racial/ethnic identity are connected to suicidality at a regional university in the Southwestern United States, Southern Utah University. In this study, 1,397 SUU Students took at least one of two surveys that asked about mental health variables and demographics. Suicidal ideation was measured using the Suicidality Suicide Behaviors Questionnaire Revised (Osman et al., 2001). Results indicate that the more minoritized identities students had, the more likely they were to be suicidal. Other findings include that LGBTQ+ students were very likely to be suicidal, cisgender students were less likely to be suicidal, and female students were more likely than male students to be suicidal. Additionally, suicidality was lowest among LDS students and highest among non-religious participants.

Genomic Analysis of Male Reproductive Skew in Bornean and Sumatran Orangutans

March 21, 2024 12:00 AM
Authors: Gabriel Hammond, Rebecca Seegraber, Tim Webster. Mentors: Tim Webster. Insitution: University of Utah. Bornean and Sumatran orangutans demonstrate pronounced differences in their social behavior. All orangutans are more solitary than other apes and monkeys, but Bornean orangutans are even less social than their Sumatran counterparts. This contrast is generally attributed to differences in forest productivity between the two islands, as feeding competition is a major cost to social behavior. Variation in sociality between the two species directly impacts male reproductive skew, or the extent to which males can monopolize reproductive success. Sex-biased demographic phenomena such as male reproductive skew can be reconstructed across a lineage’s history by comparing genetic variation across different regions of the genome. Autosomes and the X chromosome are inherited in different proportions, in a population with an equal sex ratio, four autosome copies will be passed down for every three X chromosomes. Deviations in genetic diversity from this expected ratio can be indications of sex biased demographic events. This project is leveraging differential inheritance of chromosomes to explore the role of orangutan socioecology in shaping male reproductive strategies through genomic analysis of reproductive skew across Bornean and Sumatran orangutans.

The Relationship Between Sleep, Attachment, and Social Support

March 21, 2024 12:00 AM
Authors: Kendra Johnson. Mentors: Dannelle Larsen-Rife. Insitution: Utah Tech University. This study's objective is to examine how sleep quality is related to attachment and any moderating effect from social support. Sleep quality affects multiple aspects of life including physical and mental health. About 40% of the population is affected by sleep complaints (Palagini et al., 2018). Over time, disturbed sleep can become a risk factor for mental illness and substance use disorders (Adams et al., 2014). According to Gur-Yaish et al., (2020), negative interactions related to attachment disturbances negatively affected sleep quality. Individuals with insecure attachment may be more prone to insomnia and sleep disturbances (Palagini et al., 2018). People with anxious attachment have difficulty trusting that others will be there for them when they are in need. Insecure attachment is measured on two scales: anxious and avoidant. Because of this fear, people with insecure attachment may engage in behaviors intended to reassure them of the other person’s trustworthiness. An individual with avoidant attachment tends to resist close relationships, fearing that others are not reliable (Bowlby 1982). Adults in romantic relationships tend to behave similarly to children and mothers when it comes to attachment pairing (Fraley & Shaver, 1998). When people have insecure attachment, they may be highly activated by relationship ruptures, leaving them anxious and vulnerable to poor sleep quality. The resulting poor sleep quality may be moderated by high levels of outside social support, though with high attachment avoidance, the benefits of social support are less influential. Participants (N = 94) completed the Experiences in Close Relationships-Revised (ECR-RS) scale to measure attachment, the Pittsburgh Sleep Quality Index (PSQI), and the Social Support Questionnaire-Short Form (SSQ6). Findings reveal that though the correlation between insecure attachment and sleep was small, the addition of social support revealed some interesting patterns that give insight to the relationship between attachment, sleep, and the effects of social support.

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.

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.

Assessing Risk Authoritarian Parenting and Adult Coping

March 21, 2024 12:00 AM
Authors: Hunter Mitchell, Grace Carsey, Maria Balaceanu, Peg Bird, Bridger Lisonbee, Dannelle Larsen-Rife. Mentors: John Jones. Insitution: Utah Tech University. Early experiences in the home have long-term effects on health and well-being. This study will examine the connections between parenting styles and coping mechanisms, shedding light on their implications for child development and adult mental health and well-being. Parenting styles looked at in this study, specifically authoritarian has varied views on expectations, discipline, and rewards (Doepke & Zilibotti, 2017). Parenting styles have been shown to impact how children express themselves, and more specifically their expression of anger (Radomir-Beliţoiu, 2019). The expression of anger may indicate a deficiency in healthy coping skills. When individuals are found without healthy ways of coping, they become increasingly vulnerable to mental health disorders and poor relationship satisfaction. Based on our current understanding we believe that an authoritarian parenting style will be positively correlated with unhealthy coping mechanisms such as avoidance, substance use, and self-criticism. Adult participants (N = 100) varying in ethnicity and age will be recruited to complete the Brief Cope Questionnaire (Carver, 1997) and an adaptive version of the Parenting Styles and Dimensions Questionnaire (PSDQ; Robinson, Mandleco, Olsen, & Hart, 2001) to assess their parent's style of parenting and their ability to cope with challenges. We will run an ANOVA on the collected data using SPSS. We expect to see a correlation between parenting styles and children’s coping skills. It is anticipated that there will be a strong positive correlation in unhealthy coping skills and parental strategies. This study may suggest the importance of educating children and young adults in healthier coping skills and adults in healthy parenting strategies. This education may aid in reducing the frequency and intensity of mental health crisis in adults.

Seizures & Stigma

March 21, 2024 12:00 AM
Authors: Kelsey Grimshaw, Julie Pynn, Kirsten Graham. Mentors: Kirsten Graham. Insitution: Southern Utah University. Epilepsy is the most common chronic neurological illness, yet very little is known about it. Studies have found that stigma has created challenges for people with epilepsy in economic and social capacities (Walker, 2018). It is suggested that stigma surrounding epilepsy is due to a lack of awareness (Al-Dossari, 2018). A Qualtrics survey will be administered to a sample of Southern Utah University students to solicit their awareness of epilepsy and their perceptions of stigma regarding people with epilepsy. Additionally, interviews will be conducted with a second sample of people who identify as having epilepsy to discover their perceptions regarding awareness and stigma. The results of the two samples will be compared. It is hypothesized that the stigmas identified in university students will be consistent with experiences described in interviews of people with epilepsy. The findings from this study could aid in the normalization and destigmatization of epilepsy and other chronic illnesses in society.

Examining the Effects of Service on Male-Coded Committees on the Reelection of Female Legislators

March 21, 2024 12:00 AM
Authors: Annabelle Crawford. Mentors: Celeste Beesley. Insitution: Brigham Young University. Women who run for office do not fit societal leadership expectations, which hurts their chances of being elected (Bauer 2020; Eagly and Karau 2002). Women who serve in male-coded positions face backlash for confronting issues that are incongruent with stereotypically feminine attributes (Davidson-Schmich, Jalalzai, and Och 2023). I theorize that social role incongruence is exacerbated for women who serve on male-coded legislative committees. Therefore, I predict that women who serve on male-coded committees are reelected less frequently than women who do not serve on male-coded committees. However, I propose that women with leadership roles on male-coded committees are members of the political elite and therefore will be reelected at rates similar to other legislators. This research will employ a census of female legislators from both houses of the U.S. Congress who began their tenure between 1993 and 2022, using data compiled by the Congressional Research Service. Whether a committee is male-coded or female-coded (or gender-neutral) will be determined based on whether men or women dominate the industry associated with the committee. Social role incongruence will be measured by analyzing public perceptions of female legislators during the time they served on a male-coded committee. I will use regression analysis to determine the effect of serving on a male-coded committee on a woman’s gender role incongruence. I will then compare the proportion of reelection races won by women who served on a male-coded committee to the proportion of races won by women who served on a female-coded or gender-neutral committee using difference in proportions tests. I will also compare the electoral success of women who held leadership roles on male-coded committees to the electoral success of other legislators.

From Struggles to Strength: Strategies, Identity, and Acceptance with the LGBT Community

March 21, 2024 12:00 AM
Authors: Kirsten Graham, Julie Pynn. Mentors: Kirsten Graham. Insitution: Southern Utah University. This study looks at how the LGBT+ population deals with concerns of identity, societal acceptance, and discrimination. The research identifies three primary coping mechanisms that affect resiliency: problem-focused coping, emotional coping, and avoidant coping. The purpose of the study is to determine how coping strategies and resilience relate to obstacles faced by Southern Utah University students. It makes use of qualitative data analysis, the Brief-Scale COPE, and the Brief-Resilience scales. I hypothesize with the quantitative data LGBT individuals who employ strong problem-focused skills are expected to demonstrate higher levels of resilience scoping, LGBT individuals who employ high levels of emotion focused-coping skills are expected to demonstrate low levels of resiliency, and those that demonstrate high levels of avoidant focused-coping are expected to demonstrate low levels of resiliency. Qualitative data analysis will reveal common thematic patterns in the use of problem-focused, emotion-focused, and avoidant coping skills among LGBT+ individuals, providing insights into their coping strategies related to discrimination, social acceptance, and identity. Understanding how the LGBT+ community at Southern Utah University manages to cope with challenges is crucial because it can result in better support and wellbeing. Results are forthcoming

Examining Implicit Bias on the Political Spectrum

March 21, 2024 12:00 AM
Authors: Jared Hanks, Kevan LaFrance, Julie Pynn. Mentors: Kevan LaFrance. Insitution: Southern Utah University. Implicit Bias is a form of bias that occurs subconsciously but influences conscious actions. It often occurs as racial bias and in apolitical environments (Gassner, 2014). Research shows those who are more conservative leaning are prone to racial bias (Brown, 2019). This research will broaden our understanding of implicit biases with political preferences taken into account. Using an Implicit Association Test, participants will sort "good" and "bad" words as they sort African-American or European-American faces. Research shows there is a correlation between thought compatibility and speed as connections we subconsciously hold are made faster (West, 2021). We predict those with conservative views will have a higher rate of association between black and bad words than those with progressive views, and those who lean progressive will feel they have more implicit bias when asked. this research will enhance our understanding of political bias and more importantly those who take the test will be given a chance to assess their own biases and be provided some tools to live with bias or seek to combat it. Results are forthcoming.

Development of the Positive Awe Origin Scale

March 21, 2024 12:00 AM
Authors: Willow Norton, Kaleb Cox, Jaycen Sunderman, Jessalyn Warhurt. Mentors: Kirsten L. Graham. Insitution: Southern Utah University. Positive awe is a feeling of wonder, insignificance, reverence, etc., that is stimulated by man-made or natural events, objects, or circumstances. Monroy & Keltner list the five primary domains of awe as nature, spiritual engagement, music, dance, and psychedelics, but a scale determining the exact origin points of awe has not yet been developed. Upon researching awe more and determining that it is a universally felt emotion, we started looking at where awe may stem from, or what causes it. We have found that there are different types of awe, or that different populations may be able to feel it differently, but we could not find a measure of where it originates. In our study, we attempted to determine the sources from which people experience positive awe by developing the Positive Awe Origin Scale (PA-OS). While developing the PA-OS, we delivered our scale to five peers who tested the face value of our scale about readability and subject matter, and we then edited our scale based on the feedback we received. In the present study, participants will be recruited through social media and MTurk to complete an online survey, via Qualtrics. This survey will include likert scale items rated 1 to 5, with 1 being “strongly disagree” and 5 being “strongly agree.” Psychometric evaluation of results will include a confirmatory factor analysis and an internal consistency measure using Cronbach’s alpha. Discriminant validity will be measured as we correlate our scores with other, unrelated, scales included in the Qualtrics survey, which measure different constructs. Convergent validity will be measured as participants complete an awe subscale of the Dispositional Positive Emotion Scale (DPES). We anticipate that the PA-OS will help further identify the various sources of awe and lead to improvements in the research.
