Pubertal Development and Estrous Cycling in POMC-deficient Mice
Authors: Jacob Prescott. Mentors: Zoe Thompson. Insitution: Utah Valley University. The pro-opiomelanocortin (Pomc) gene encodes POMC, which is differentially processed to produce adrenocorticotropic hormone (ACTH), beta-endorphin, and three melanocyte-stimulating hormones, among other peptides. POMC neurons are principally located in the arcuate nucleus (Arc) of the hypothalamus, where they are essential in the control of food intake, energy expenditure and body weight. Several different mutations in the POMC gene have been shown to cause early-onset obesity and adrenal cortical insufficiency in humans. We are working with a mouse model with a hypothalamic-specific POMC deficiency. These mice exhibit hyperphagia, early-onset obesity, and also seem to be infertile. We are interested in examining potential differences in pubertal development, as well as reproductive function. Specifically, we will examine day of vaginal opening, day of first estrus, and estrus cycling in juvenile female POMC-deficient mice. The estrus cycle has four stages: proestrus, estrus, metestrus and diestrus. Although hormone levels in the blood differ during the four stages, these are difficult and expensive to measure. A less invasive measurement is to take vaginal cell samples each day and examine them under the microscope. Three different types of cells are present in different ratios depending on the stage of the cycle: nucleated epithelial cells, leukocytes, and cornified epithelial cells. We will track estrus cycle changes during pubertal development and after to see if there are differences between wildtype, heterozygous, and homozygous POMC-deficient mice.Learning more about how POMC-deficiency affects reproductive function may help us understand more about the link between obesity and infertility.
Methods for assessing Ephydra gracilis populations across Great Salt Lake
Authors: Cora Rasmuson, Carly Biedul, David Herbst. Mentors: Carly Biedul. Insitution: Westminster College. Great Salt Lake (GSL) is a unique ecosystem known for its elevated saline conditions, supporting diverse biological communities. However, GSL's vital habitats for birds and invertebrates are diminishing due to climate variability and water diversions. The keystone species, Ephydra gracilis, known as brine flies, is central to this ecosystem's food web.Microbialite mounds of haloarchaea, algae, and cyanobacteria sustain E. gracilis, but receding shorelines and record-low lake levels intensify salinity, reducing food sources and brine fly survivability. This decline has far-reaching consequences, as E. gracilis accounts for over 50% of the diet for 10 million migratory birds at GSL.Ongoing research is focused on refining methods for monitoring populations of Ephydra species in response to changing salinity and elevation levels. This research is vital for the preservation of the lake's ecosystem and biodiversity.
Identifying and photographing the instars of a parthenogenetic mayfly (Centroptilum trianguilfer; Ephemeroptera)
Authors: Heidi Kipp, Annika Jones, . T. Heath Ogden. Mentors: T. Heath Ogden. Insitution: Utah Valley University. The purpose of this research is to identify and document mayfly instars from a parthenogenetic population of individuals being raised in the lab. Instars are the developmental stages of an arthropod between molts. Mayflies (and other non holometabolous insects) go through incomplete metamorphosis, moving from egg to nymph stages, and then to subimago (unique to mayflies), and imago (or adult). Previous research indicates the number of instars to be between 12-45 depending on the species, and the species we studied is estimated to have around 15. During each instar, mayflies shed their exoskeleton. The difference between each instar is vital to understanding the changes in gene expression and overall life cycle of a species. Instars have subtle differences, and identifying them will help further research into which genes are involved in producing specific morphological characteristics. Defining these structures, such as the forming of eyes or wings, are of particular interest in evolutionary phylogenetics. We raised Centroptilum trianguilfer (Ephemeroptera: Baetidae) in a controlled water tank, collecting and dating egg samples from mature imagos. Water is maintained with standard ion composition with 130-400 conductivity. Once the eggs hatched, we performed daily inspections and measurements using a 40x stereomicroscope microscope and Lumenera Infinity Analyze. We are using basic appearance, size and morphology) to separate instars. We will identify and photograph each instar. Samples from the different instars, subimagos, and adults will be acquired and used to generate transcriptome data. We propose that our research will aid in the investigation of mayfly evolution and their genetic mechanisms of control.
Cultivation of bacteria from PCB-contaminated sediments PCB Degradation
Authors: Akir Rowe, Hali Hutchinson, Kingdom Wanjoku. Mentors: Katrina Twing. Insitution: Weber State University. Polychlorinated biphenyls (PCBs) are toxic chemicals popularly used in electrical manufacturing companies from the 1930s - 1970s. PCBs, colloquially known as ‘forever chemicals’, are known to cause significant health concerns and are notoriously difficult to remove from an environment. PCBs are currently banned in the US; however, they can still be found in the environment due to improper disposal methods. This research aims to better understand ecological networks, genomic novelties, and potential bioremediation of microbes from PCB-contaminated environments. Microcosm cultures were developed to resemble the original conditions of the environmental samples, containing PCB-contaminated mud from Woods Pond, Lenox, Massachusetts, and filtered pond water with three different treatments: aerobic, anaerobic, and anaerobic with the addition of sulfate. These cultures have been growing for five months, showing signs of active microbial metabolism (e.g., rust patches in sediment gas production). The microcosms were used as inoculum for agar containing PCBs, and 30 PCB-tolerant colonies were isolated, with some belonging to known PCB-degrading taxa of Paenibacillus, Clostridium, Rhizobium, Methylversatalis, and Sphingobacteria. Future analyses will be conducted to (a) identify the microbial diversity within the microcosms via 16S rRNA amplicon sequencing, (b) explore the metabolisms within the microcosms, and (c) further characterize the isolated PCB-tolerant bacteria. This data will aid further research to determine if and how these microbes metabolize PCB compounds.
Microbiome of PCB Contaminated Sediments
Authors: Jerzee Findlay, Gina Fuller. Mentors: Katrina Twing. Insitution: Weber State University. Polychlorinated Biphenyls (PCBs) are toxic chemicals which were popularly used in electrical manufacturing companies from the 1930s - 1970s and are known to cause significant health concerns for humans even today. These have also been termed “forever chemicals” due to their ability to bind to sediments and soils, which results in difficulties with removal or degradation in contaminated environments. One site of widespread PCB contamination is Pittsfield, Massachusetts, where improper disposal of industrial waste by a General Electric plant has led to chronically contaminated rivers and ponds, even decades later. The aim of this research project is to learn more about the microbial communities that coexist with these toxic forever chemicals, hoping to find evidence that they can degrade PCBs through metabolism. This specific study within the project focuses on microbial diversity of sediment samples collected from the contaminated Woods Pond, located downstream of the Pittsfield General Electric plant.: We performed DNA extractions, PCR amplification, and 16S rRNA amplicon sequencing on an Oxford Nanopore MinION DNA Sequencer. Preliminary data suggest that the samples contain genera known to be associated with PCB degradation, such as Paenibacillus, Clostridium, Rhizobium, and Sphingobacteria. With this understanding, future efforts aim to evaluate the ability of these environmental bacteria to degrade PCBs.
Cultural humility impacts on premature termination in psychotherapy
Authors: Logan Walker, Kate Coneys, Nick Tops, Russ Bailey. Mentors: Russ Bailey. Insitution: Utah Valley University. Background: Cultural humility is an influential concept in Multicultural Orientation therapeutic research (Owen et al, 2011). Cultural humility is defined as “a lifelong process of self-reflection and self-critique whereby the individual comes to value and respect cultural diversity, recognizes his or her own biases, and is open to learning from others" (Tervalon & Murray-Garcia, 1998, p. 117). Cultural humility practices attempt to address cultural differences in therapy. Therapy absent of cultural humility can run the risk of failing the needs of culturally diverse clients. Racial and ethnic minorities are more likely to experience premature termination (Owen et al., 2015). Premature termination is defined as when a client begins an intervention but discontinues prior to recovering from the problem that he or she sought treatment for against provider recommendations (Swift & Greenberg, 2012). Premature termination is a significant concern as those who do not complete an intervention are less likely to experience symptom relief or meet their treatment goals (Steinberg et al., 2019). hope to better understand the link between cultural humility and premature termination/treatment deterioration in therapy in college students. We hypothesize that lower therapist’s cultural humility will be associated with an increased likelihood to unilaterally terminate therapy prematurely or show treatment deterioration. Methods: Data was collected from students who participated in therapy at the Utah Valley University Student Health Services from 2021-2023. The sample size for this dataset is approximately 560 participants. We will use two different operationalizations of premature termination/treatment deterioration: 1. Clients who reported have attended therapy for at least 3 sessions, has at least 1 cultural humility datapoint, and reported feeling “worse than at intake” on an item of subjective progress during at the last attended session with no future sessions scheduled for at least 90 days. 2. Clients who scored worse or the same on well-being indictors (PHQ-9 and GAD-7) and reported feeling “the same as intake” or “worse as intake” on an item of subjective progress during the last attended session with no future sessions scheduled for at least 90 days.. Clients completed the Cultural Humility Scale (Hook, 2013) and microaggression items at the beginning of their 3rd session and then every 4 sessions (e.g., session 7, 11, etc.). Clients completed the PHQ-9, GAD-7, and subjective progress items at the beginning of every session. We will use logistic regression to see how cultural humility scores and microaggression frequency/impact predict premature termination/treatment deterioration. Results: Results from the analyses will be presented during the poster presentation Discussion: The results of the study will help us determine if therapist's cultural humility is related to client premature termination. If we find support for our hypothesis, this means that cultural humility is an important factor in therapeutic processes that has direct impact on the effectiveness for therapy interventions. However, rejecting our hypothesis may suggest that cultural humility is not an important aspect of premature termination. Limitations of this study include potential ceiling effects due to therapists striving to be cultural humble and thus limiting the variability in our sample.
Mayfly Wing Wonders: Uncovering Genetic Threads in Parthenogenic Individuals using RNA
Authors: Melissa Rangel, Avery Larsen, Heath Ogden. Mentors: Heath Ogden. Insitution: Utah Valley University. Mayflies, also known as ephemeroptera, are members of the first group of insects that evolved the ability to fly(Gillott, 2005). Distinct developmental characteristics of the life stages of the mayfly are the reason that Ephemeroptera are of particular interest.The aquatic nymph stages do not have wings, but they do possess abdominal leaf-shaped gills, and in some cases gills associated to the legs. The abdominal gills can sometimes be used to help propel the insect through its environment (Eastham, 1936) in addition to performing gas exchange. Centroptilum triangulifer (family Baetidae), will be used for RNA extractions to study the developmental genetic profiles for characteristics such as wings and gills. Objectives for this research are 1). Acquire samples from different instars, subimago, and imago. 2) Perform 10 RNA extractions. 3) Use Qubit technology to ensure ≥ 20 ng/μL RNA concentration per ≥ 10 μL. 4) samples will be packaged in thermo-stable shipping boxes and sent to Novogene where samples are tested once more for quality control. 5) Once quality is confirmed, samples will be sent and processed by Novogene. 6). Using an in-house bioinformatics workflow, RNA data will be checked for quality, trimmed, aligned, and assembled. The assembled contains will be used to search for genes of interest. 7) the resulting RNA expression profiles will be compared across the installs, sub imago, and imago and to other expression profiles from other related insects.
Kynurenine Deamination and Synthesis of Xanthommatin
Authors: Stephen Chamberland, Craig D. Thulin, Katherine Solorzano, Cassandra Beddes, Nathan Twitchell, Abram Caruso. Mentors: Steve Chamberland, Craig D. Thulin. Insitution: Utah Valley University. This investigative procedure is a continuation of an experiment done by UVU undergraduate student Kyra Banks and her mentor, UVU Professor of Chemistry Craig Thulin, to determine the structure of xanthommatin. Xanthommatin is one of the primary pigments found in monarch butterflies, and many other insects. Data obtained during the mass spectrometric analysis was observed to indicate a possible deamination of xanthommatin, however the quantity of deaminated xanthommatin observed was too small and so the structure could not be determined. The research investigates the precedented deamination of kynurenine as a model to develop a procedure for the deamination of 3-hydroxykynurenine, primarily due to the fact that it is cheaper in price to xanthommatin, as well as a chemical precursor that can be used for the synthesis of xanthommatin. The implications of this suggest that the deamination procedure developed for 3-hydroxykynurenine could be successfully replicated with xanthommatin. After the deamination procedure has been successfully repeated, xanthommatin will be synthesized using one of a few procedures developed by Kumar, A., et al1. Once a sufficient sample of xanthommatin has been successfully synthesized, the deamination procedure will be repeated on samples of xanthommatin to determine the structure of deaminated xanthommatin using NMR spectroscopy. The research conducted here is beneficial not only because it is a continuation of other UVU student’s and staff’s work, but also to those whose work is in the animal biology realm of science. The information that will be extracted from this research will spearhead new research pathways and questions to be explored.Xanthommatin-Based Electrochromic Displays Inspired by Nature (acs.org)Biomimetic Colorants and Coatings Designed with Cephalopod-Inspired Nanocomposites (acs.org)
Brain-eating amoeba rescue-of-infection model using drug combinations
Authors: Karissa Bauer, Kennedy Lewis, James Belnap, Andrew Torena, Braden Freestone, Luis Montenegro Calla. Mentors: Daniel Clark. Insitution: Weber State University. In the United States, 157 documented cases of primary amoebic meningoencephalitis (PAM) have been recorded between 1962 and 2022. In the 60 years since the first reported case, only four patients have survived; a 97.5% fatality rate. The causative agent responsible for the highly fatal infections, is the free-living, single-celled parasite, Naegleria fowleri— or the “brain-eating amoeba.” The aquatic thermophiles are opportunistic pathogens that inhabit a wide range of environments; from poorly maintained pools, moist sediment, rivers, lakes, etc. Exposure to N. fowleri invasion is reliant on direct contact with a host’s upper nasal mucosa, and the active parasite. Rapid deterioration of neural tissues occurs shortly after infection.Today, there is no universally accepted treatment plan for treating PAM infections. The CDC has recommended an empirical approach to treatment, and suggests utilizing combination drug-therapies. Suggested drugs include Amphotericin B, Azithromycin, Fluconazole, Miltefosine, and Rifampin. To better understand and evaluate the effects of these drugs on N. fowleri, a rescue-of-infection model was applied to test the efficacy of single and combination-drug treatments, at various time points. The model utilized an immortalized HeLa cell line that was infected with the amoebae until roughly 50% cytotoxicity was observed. The rescue stage commenced with drug additions, and HeLa cell metabolism, and apoptosis levels were monitored using fluorescence viability assays and caspase-3 enzyme detection systems. Drug combinations that included Rifampin and Amphotericin B, provided the greatest protection for human Hela cells against N. fowleri infections. Data collected from this model provides deeper understanding of Naegleria fowleri pathogenicity. This knowledge will aid the development of more reliable and efficient treatments for this devastating infection.
Relationship with soul: a short excursion in psychology and religion
Authors: Genna Howard, Cameron John. Mentors: Cameron John. Insitution: Utah Valley University. In the history of psychology, the concept of soul played a significant role informing philosophy and theory. In the late 1800’s many questioned the concept of soul in favor of measurable concepts that aligned with the scientific method, distinguished from religious classification that were deemed unworthy of pursuit. In the emergence of the science method, the concept of soul faded and the field of psychology experienced soul-loss, becoming soul-less. After nearly 150 years, there is a movement in the field advocating for soul to return to its former status by shedding light back onto the soul. For some, soul is aligned with religious thought. Religions are experiencing a loss of congregants, members engaging in faith transitions, and experiencing soul-loss. This paper will compare and contrast what happened in psychology with the experiences of some in religious organizations while looking at how the emotion of fear plays a part in both organizations. The methodology utilizes historical concepts and experiences shared by the brave souls who are challenging the current beliefs in both fields. In addition, anecdotal, informal information provided by individuals close to the authors is used to emphasize the practical application of this crisis in psychology and religions with the goal of reigniting a passion for soul.
Change Over Time: Cultural Humility and Microaggressions in Therapy
Authors: Kate Coneys, Nick Top, Russ Bailey, Logan Walker, Julia Toomey. Mentors: Russ Bailey. Insitution: Utah Valley University. Background: Past literature has emphasized the importance of practicing culturally competent care and has shown that higher clinician cultural humility, as well as a lower frequency of microaggressions occurring in therapy, have been associated with more desirable therapeutic outcomes in retrospective, cross-sectional studies. However, research has also shown that patient outcomes appear to be unrelated to their therapist's experience level (Erekson et al., 2017), suggesting that more experience may not lead to being a more effective therapist, including more culturally humble. Despite the breadth of research on the significance of cultural competence, less is known about how a therapist's cultural humility changes across treatment with a particular client, or how a therapist’s cultural humility changes over an extended period. The aim of the current study is to examine this concept by analyzing both the relationship between the number of sessions spent working with a given therapist and a client’s rating of the clinician’s cultural humility, as well as the relationship between the average cultural humility rating of the therapist and time. We will also examine how the impact of microaggressions occurring in therapy changes during the course of therapy. Hypotheses: It is hypothesized that the results of this study will show a positive association between the number of sessions with the same therapist and their cultural humility, as rated by the client, as well as a negative association between the number of sessions and the impact of microaggressions reported by the client. Additionally, it is hypothesized that the therapist’s cultural humility rating over the entire course of data collection will not change to a statistically significant degree. Methods: We used archival data collected by Utah Valley University’s Student Health Services Counseling Center from August 2021 – September 2023. This archival dataset consists of 564 clients with at least one cultural humility and microaggression data point. Beginning at the third session, and occurring again every four sessions, clients were asked to rate their clinician’s cultural humility, using The Cultural Humility Scale (Hook et al., 2013), and report the frequency and impact of microaggressions that had occurred during the last four sessions. We will analyze the data using multi-level latent growth modelling. Results: Results will be presented as part of the poster presentation. Discussion: If the results of this study agree with the hypothesis, the implications may be that cultural humility improves over time with specific clients, potentially explained by growth of therapeutic alliance over time. However, it may also imply that a therapist’s cultural humility does not improve over extended time periods, showing that cultural humility appears to be static rather than dynamic. If the results do not agree with the hypothesis, this may imply that a client’s perception of their therapist’s cultural humility is static, but that over extended periods of time a therapist’s cultural humility can improve, implying that it is trainable.

UTAH'S HERITAGE: A LITTLE KNOWN STORY OF MORMONISM AND EUGENICS
Authors: Lindsay Beekman. Mentors: Olga Kopp. Insitution: Utah Valley University. This research probes the primary historical newspapers of early 1900s Utah, providing insights into the cultural atmosphere of the time and the widespread support for the Eugenics movement throughout the state. Our findings indicate that out of 72 distinct newspaper articles discussing Eugenics in Utah between 1908 and 1938, 62 conveyed a positive perspective, 9 remained neutral, and only 1 expressed opposition. Notably, from 1947 to 1996, leaders of The Church of Jesus Christ of Latter-Day Saints administered the ‘Indian Student Placement Program’ or ‘Lamanite Placement Program,’ aligning with many Eugenics principles. Utah, like many places worldwide, embraced Eugenics with open arms.
Deciphering the Impact of Pomc Mutation on Mouse Reproductive Behavior: A Comprehensive Data Analysis Approach
Authors: Lauren Silvatti.. Mentors: Zoe Thompson. Insitution: Utah Valley University. Proopiomelanocortin (Pomc) deficiency, stemming from a mutation in the Pomc gene, presents a myriad of health challenges, including extreme hyperphagia, early-onset obesity, and infertility. This study leverages a mouse model exhibiting Pomc-deficiency to delve into the root causes of infertility. While the correlation between obesity and fertility is well-established, our primary focus is to discern whether the POMC mutation independently contributes to reproductive challenges. Our investigation extends into the interplay of genetics, endocrinology, and obesity through data analysis using R, with an emphasis on deploying advanced statistical models.Video recordings of sexual behavior interactions have been analyzed manually, with independent observers marking each behavior. The frequency and duration of each behavior will be compared among three groups of pairings: wildtype-wildtype, heterozygote-heterozygote, and homozygous POMC-deficient mice. Techniques will include data cleaning, timestamp manipulation, and behavior categorization in R, a programming language commonly used for data analysis. To discern patterns and variations, our analysis will also employ statistical models such as linear mixed-effects models. We can account for potential confounding variables and significant differences in durations of previously identified important reproductive behaviors. Visualization tools, including box plots and violin plots, will provide an initial glimpse into the distribution of behavior durations. Subsequently, we plan to conduct inferential statistics, employing techniques such as Analysis of Variance (ANOVA) to assess the significance of differences across multiple groups. Our investigation extends beyond descriptive statistics, with a focus on predictive modeling. Regression analyses will explore potential relationships between behavior durations and reproductive success. Machine learning algorithms will be applied to uncover complex interactions within the dataset.The anticipated results promise not only a nuanced understanding of the interplay between Pomc mutations and reproductive challenges but also the identification of potential biomarkers or predictors of successful reproduction. This comprehensive statistical approach contributes significantly to the fields of genetics, endocrinology, and obesity research, offering a robust framework for future investigations into the intricate relationship between genotype and behavior.
Construction Techniques in Ancient Fremont Pithouses
Authors: Ellie Martin. Mentors: Mike Searcy. Insitution: Brigham Young University. As part of the 2023 Hinckley Mounds excavation, BYU Field School participants excavated a sizable amount of beam-impressed adobe and burnt wooden beams from the partially excavated pit house. This research proposal will focus on these two types of artifacts and what can be learned about the Fremont people through their study. Specifically, in this research project I will attempt to answer the question of what specific types of wood and adobe were used, and how they were used together to build the Fremont pithouse. To do this, the charcoal will be sent in for wood testing to get dates and tree type. I will also test the beam-impressed adobe to understand the type of clay used to make the hardened adobe. Finally, I will study the beam impressions in the adobe to find the average diameter of the beams used in the pit houses, any outliers in the diameters, and analyze any visible angles on corner pieces to put together a picture of how the beams and adobe came together to form the skeleton of the pit house structure. This research has the potential to reveal much about the Fremont people that lived at Hinckley Mounds, and help us to better understand their living conditions. The research that I conduct will potentially generate data about the age and type of wood used in their living structures, the diameter of the wooden beams they used, and the angles of the corners of the structure. At the conclusion of this research we aim to gain a better understanding of how the Fremont people constructed their dwellings, from the materials to their methodologies. I anticipate finding that the trees they used were locally sourced and date to a similar period of the other dates that we have from the Hinckley Mounds site, between 700–1300 CE. The pithouse will likely prove to be sub-rectangular, similar to Structure 1 at the Hinckley Mounds site, although any angles that can be found in the adobe impressions could give more precise data. All of this new data may serve to provide more insight into how the Fremont lived and chose to operate in their society.
Trace Metal Concentrations of Various Land Use Types Surrounding Utah Lake
Authors: Alex Montgomery, Mason Gordon. Mentors: Eddy Cadet. Insitution: Utah Valley University. TRACE METAL CONCENTRATIONS OF VARIOUS LAND USE TYPES SURROUNDING UTAH LAKEMason Gordon, Alex MontgomeryKeywords: Trace metals, Soil, Land use, Utah LakeUtah Lake has a history of anthropogenic impacts that have resulted in the accumulation of trace metals (TMs) in the sediments of this region. Previous studies have evaluated the water and saturated soils, but have not provided a complete picture of the human impact on upland soils. Some pollutants may be contained in unsaturated soils and never enter the water due to the inherent soil characteristics and chemical properties of the TMs. Elevated concentrations of TMs in the environment pose hazards to the ecosystem and local residents. These impacts can be better understood by evaluating TMs in unsaturated upland soils. In this study a comparison of TMs in saturated wetland and unsaturated upland sediments, as related to anthropogenic sources, was completed. This study analyzed the types and concentrations of TMs to understand their mobility throughout the ecosystem. 52 core samples were collected from the saturated and unsaturated soils in eight sites. These sites represent recently developed areas (New Dev), more established areas (Mid Dev- those that have been developed over five years), recreational areas, mining areas, industrial areas, agricultural areas, and a wastewater treatment plant site. The soil samples were dried, ground, sieved, acid digested, and analyzed in the ICP-OES for TM (As, Pb, Cu, Cr, Cd, and Zn) content. Preliminary results show that TM concentrations in upland sediments were higher than those in wetland sediments. Cr levels in industry and Mid Dev are 43.0 ppm and 47 ppm, respectively. Saturated sediments at the same sites revealed Cr levels of 23 ppm and 21 ppm, respectively. This indicates that TMs are contained in unsaturated sediments. Of the observed land use types, Mid Dev is the most impacted, having the highest elevations of TM levels on average. Cd concentrations exceeded background levels in both New Dev (.97 ppm) and Mid Dev (.83 ppm). This is indicative of anthropogenic impact, as developed areas have higher TM content. The statements of this study will provide information to regulatory authorities in order to create policy to improve human health.
Another Look at Underlying Mortality Model Used in Life Insurance Industry
Authors: Benjamin Furniss, Britton Borget, John Sanders. Mentors: Patrick Ling. Insitution: Utah Valley University. Mortality model is the underlying model used by life actuaries to price life policies, set reserve amounts, and compute policy values. A mortality model investigates how mortality rates evolve over time. Current insurance law in many states (including Utah) suggest the use of Scale AA (or a similar model) in projecting future mortality rates, which is a special case of autoregression time series model. This model is flawed because it is built on the assumption that (1) there is no ARCH effect in the central death rates data, and (2) there is no unit root in the time series of mortality index. These assumptions are questionable. No wonder why state insurance laws (including Utah state insurance law) are recently revised in recognition of discrepancy between model predicted mortality rates and actual mortality rates. Recent published literatures indicate that the second assumption is questionable, as some statistical tests suggest that there is some near unit root in the mortality model. In this talk we want to argue that ARCH effect is present in the mortality data, so there is need to adopt a time series model that incorporates heteroskedasticity in the mortality data. We will later propose a GARCH model for better predicting future mortality rates – a key task life actuaries conduct, for it is important for life actuaries to predict what will happen over the next few decades of policy term.
Artificial black holes: are they a threat to humanity?
Authors: Tate Thomas. Mentors: Alexander M Panin. Insitution: Utah Valley University. We wanted to see if accidentally creating mini black holes in high energy particle collisions posed a real threat to humanity. To do this, we calculated some properties of such a black hole, such as its life span, radius, density, and minimum energy required. We found that it is unlikely to exist, let alone destroy the planet. Furthermore, we calculated what would happen if it were to exist, finding that it would move through the Earth with little resistance and with a small amount of Earth matter absorbed. Depending on initial velocity, the black either quickly escapes Earth or would settle orbiting it with the orbit part of which passes via Earth. It is interesting that in a simplified model of Earth as of a sphere of uniform density, the inner part of the orbit of black hole is also elliptical (as the outer is) but not Keplerian - with Earth center not at the focus but at the center of another ellipse. In the case of small initial velocity when entire orbit is inside Earth, the period of such inner orbit is constant regardless of birth location and initial velocity of black hole. The goal of this presentation is to discuss the results of our calculations and to explore potential applications to our understanding of interaction of mini black holes with ordinary atomic matter.
HEIGHTS IN THE abc CONJECTURE. AN UNDERGRADUATE APPROACH.
Authors: Brantson Yeaman. Mentors: Machiel van Frankenhuijsen. Insitution: Utah Valley University. There has been considerable curiosity at the graduate and postgraduate level in regards to heights, that is, heights in their relation to Diophantine geometry. One application of heights is in the $abc$ conjecture, which remains highly mysterious. Often, the only height undergraduates encounter is the traditional absolute value. This talk seeks to define the height for use in investigating the $abc$ conjecture and connect it at a level that undergraduates with little experience with number theory may approach. It will introduce the idea of a $p$-adic norm of a number, a projective point, and a view that lends itself to both a simple idea of distance, and yet has an analogue in the Hamiltonian numbers.
Asexual Aviators: Transcriptome Profile of the Life Stages of a Parthenogenic Mayfly
Authors: Avery Larsen, Heath Ogden. Mentors: Heath Ogden. Insitution: Utah Valley University. Mayflies, also known as Ephemeroptera, are members of the anciently derived infraclass known as Paleoptera, the first group of insects that evolved the ability to fly (Gillott, 2005). Distinct developmental characteristics of the life stages of the mayfly are the reason that ephemeroptera are of particular interest. The life stages are; the egg, nymphs, subimago, and imago. The aquatic nymph stage does not have wings but instead has leaf-shaped gills that can be used to help propel the insect through its environment (Eastham, 1936). Centroptilum triangulifer will be used for RNA extractions to study the development of both wings and gills. Objectives for this research are 1). Elucidate, describe, capture, and record distinguishing characteristics of the different instars of Centroptilum triangulifer. 2) Identify key instars integral to gill and wing development in Centroptilum triangulifer. 3) Perform 10 RNA extractions. 4) Use Qubit technology to ensure ≥ 20 ng/μL RNA concentration per ≥ 10 μL. 5) samples will be packaged in thermo-stable shipping boxes and sent to Novogene where samples will be tested once more for quality control. 7) Once the quality is confirmed, samples will be processed using poly-A enrichment and then sequenced using high-throughput Illumina sequencing. Data will be tested for quality control and then sent to Ogden labs. 8). Using an in-house bioinformatics workflow, RNA data will be checked for quality, trimmed, and aligned, before RNA data is first trimmed, and then aligned to Ogden labs transcriptome reference genome. After alignment, the number of reads per gene, or hit counts, are calculated and compared. 9) RNA results of different instars will be compared to each other as well as NCBI databases using the Basic Local Alignment Search Tool.
Exploring the Differences Among Attachment Styles with Cognitive Appraisal and Emotional Suppression
Authors: Rebekah Hakala, Moroni Black. Mentors: Todd Spencer. Insitution: Utah Valley University. Over the years countless studies have delved into the theory of attachment due to its influence in the field of child development. Attachment theory is the idea that the sensitivity of parents or caregivers to a child’s bids for attention affect how the child will bond in relationships (Bretherton, 1992; Wilson-Ali et al., 2019). The style of attachment that a child has can affect them long-term and may influence other relational and developmental characteristics (Kurth, 2013). Due to the influence of attachment, our study investigates the relationship it has with cognitive reappraisal. Cognitive reappraisal is the ability to regulate one’s emotional states and the idea that a change in these thoughts is necessary to change negative emotions (Troy et al., 2017; Clark, 2022). With its ability to process and regulate emotion, cognitive reappraisal is another influential characteristic to the human psyche. Our results and analysis of the relationship between attachment theory and cognitive reappraisal come from a quantitative survey.The purpose of the present study is to examine the relationship among attachment styles and Cognitive Reappraisal. Our sample consists of 411 married individuals. Participants completed The Relationship Questionnaire (RQ; Bartholomew & Horowitz, 1991) and Emotion Regulation Questionnaire (ERQ; Gross & John, 2003). Results of the one way Anova were significant F (3,407) = 3.36, p=<.01. There was a significant difference in levels of cognitive reappraisal among attachment styles. Secure attachment (M=29.95, SD = 6.41), fearful attachment (M=27.27, SD = 5.92), preoccupied (M=27.99, SD = 7.27), and dismissing (M = 28.78, SD = 7.54). Results of the Bonferroni Post-hoc analysis indicated a significantly higher levels of cognitive reappraisal than attachment styles (p.<.001). Results provide empirical support that secure attachment styles tend to be beneficial for cognitive reappraisal.
MRSA induced biofilm clearance by bacteriophage and antibiotic.
Authors: Rainey Hughes, Avalon Marker, Elizabeth Bouwhuis, Yeshaswini Dudde, Bryan Dopp, Scot Carington, Jared Nelson. Mentors: Daniel Clark. Insitution: Weber State University. Antibiotic resistance is a pressing concern within the medical community as bacteria's resistance to antibiotics is escalating alongside the increased usage of antibiotics. According to the CDC, there are close to 2.8 million antibiotic resistant infections every year, with about 35,000 of them resulting in death. This issue has prompted antibiotic stewardship programs in clinics and hospitals to avoid adding to the list of resistant bacteria. Staphylococcus aureus, including the formidable methicillin-resistant S. aureus (MRSA) strain, poses a grave threat due to its antibiotic resistance. The challenges stemming from this resistance become even more formidable when these infecting bacteria assemble into biofilms. Biofilms are robust, adhesive layers composed of bacteria and their extracellular matrices of polysaccharides, proteins, and DNA. In clinical environments like hospitals, biofilms frequently develop on medical devices such as stents, catheters, and IV lines, as well as on metal and plastic surfaces of medical equipment. These biofilms exacerbate antibiotic treatments due to incomplete eradication; the most resilient bacteria persist after exposure. There is evidence indicating that bacteriophages, which are viruses that will a target particular species or strain of bacteria, have the ability to encode depolymerases. These depolymerases can identify biofilms, adhere to them, and subsequently break down extracellular polymeric substances. Furthermore, bacteriophages can produce lysins, which induce bacterial cell death through cellular lysis. These characteristics can potentially render the bacteria more susceptible to antibiotics. The use of bacteriophages can also be beneficial when it comes to the concern of opportunistic infections. Due to its selectivity to specific bacteria, it can attack the target hosts and leave the natural flora intact.In our research, we have induced biofilms in our bioreactor. With these biofilms we have been able to test different concentrations of multiple antibiotics, including Vancomycin, Oxacillin, and Carbenicillin in combination with phage K at different concentrations. Our research is aimed at showing a synergistic relationship between phage K and antibiotics, that will allow a subinhibitory concentration of both, in combination, to induce a complete kill and clearance. We have measured this by evaluating bacterial growth via absorbance measurements at 600nm in a Tecan plate reader. We have also measured biofilm clearance using the plate reader and measuring fluorescence at 630nm with a biofilm tablet assay. It was found that a subinhibitory concentration of antibiotic alone did not induce a complete kill and clearing, and that a subinhibitory concentration of phage alone did not induce a complete kill and clearing. However, once these concentrations were used in combination with each other, the complete clearing and killing of MRSA was achieved, and furthermore, was achieved with the antibiotic that the staphylococcus aureus is resistant to. Leading us to believe that we have found a renewed use for a currently ineffective defense mechanism.
Development of the midwestern blot technique for elucidation of pigment-binding proteins
Authors: Tessa C Black, Craig D Thulin. Mentors: Craig Thulin. Insitution: Utah Valley University. Monarch butterflies (Danaus plexippus) are a distinctive and beloved species due to their unique wing coloration. In 2022, UVU student Kyri Forman and Dr. Craig Thulin identified seven pigments in monarch butterfly wings, three of which have not yet been identified in any other organism. The novel pigments are modified versions of xanthommatin, and their discovery implies the existence of presently unknown enzymes which catalyze the pigments’ biosynthesis. The western blot and its modified technique, the far western blot, are useful tools for identifying protein-protein interactions using antibodies and bait-proteins, respectively. To identify xanthommatin-binding proteins present in monarch butterfly pupae, we are developing a new blotting technique which we are calling the midwestern blot. This technique uses pigment molecules to identify the presence of pigment-binding proteins within a mixture. The midwestern blot technique will be validated is being validated using cytochrome C, hemoglobin, and myoglobin, three heme-binding proteins of known molecular weight and structure. Once validated, we will use the midwestern blot to identify xanthommatin-binding proteins extracted from monarch butterfly pupae. The midwestern blot will help promote future investigations into pigment-binding proteins, including the enzyme responsible for the novel pigments identified in monarch butterfly wings.
Efficiently and Accurately Simulating Coupled Nonlinear Schrödinger Equations with Exponential Time Differencing and Fourier Spectral Methods
Authors: Nate Lovett. Mentors: Harish Bhatt. Insitution: Utah Valley University. Coupled nonlinear Schrödinger equations (CNLSEs) are an extension of the nonlinear Schrödinger equation (NLSE) that applies to multiple interacting wave systems. They occur naturally in many physical systems, including nonlinear optics, multi-component Bose-Einstein condensates, and shallow water waves. Solitons, which are self-contained, localized wave packets that preserve their shape and speed during propagation, are a significant application of CNLSEs. Solitons are prevalent in nonlinear systems and play a critical role in long-distance information transmission in telecommunications. Despite their widespread use in various fields, solving CNLSEs analytically is challenging, and numerical approximations are necessary. However, solving CNLSEs numerically is a difficult task because of their high nonlinearity.To overcome this challenge, in this presentation, we will introduce, analyze, and implement an established fourth-order Exponential Time Differencing scheme in combination with the Fourier spectral method for simulating one-dimensional CNLSEs. In order to check the performance of this method in terms of accuracy, efficiency, and stability, we will present simulation results on CNLSEs. Our results will consider single, two, and four soliton interactions for homogeneous Neumann, homogeneous Dirichlet, and periodic boundary conditions. The numerical results will show that the proposed method is able to preserve energy and mass for a long time simulation in soliton interactions, as well as preserve the expected order of convergence for the proposed method.
Power Scaling a Nd:YVO4 Laser for Use as the Optical Drive of a Long Wave Infrared Optical Parametric Oscillator
Authors: Alexander Gibb. Mentors: York Young. Insitution: Utah Valley University. Our research group’s long term goal is to build a student-constructed nonlinear optical system to create a tunable source of longwave infrared (LWIR) photons for probing molecules for early detection of disease in human tissue. I previously developed a diode laser system as the optical pump for a 5 Watt Nd:YVO4 laser which was reported at UCUR in Feb 2023. However, recent nonlinear optical calculations for our optical parametric oscillator (OPO) show that we will need the average laser power from that Nd:YVO4 laser to be in the 7-8 Watt range. My work to power scale the Nd:YVO4 laser is described in this presentation.
A Gyroscopic System for Magnified Coherent Diffraction Imaging
Authors: Tyler Daynes, Jair Gonzalez, Jeremy Tait, Josh Jumper, Ellie Purcell, Tyler O'Loughlin, Vern Hart. Mentors: Vern Hart. Insitution: Utah Valley University. Coherent diffractive imaging is a common method for resolving small objects such as cells in order to determine their morphology. In it's essence it takes the diffraction pattern of laser light attenuating through an object and computationally reconstructs them back into the image that the light goes through. On the downside resolution of these diffraction patterns resulting from CCD size and sensitivity can be poor resulting into a less than optimal reconstruction. We have set out to build a system that can magnify this diffraction pattern without distorting the original image of the pattern. We have done this by building our own rastering system that can magnify light on the far edges of our beam. It does this by taking images with a lens attached to the rastering camera. This also has a problem because when the camera moves our detected light quickly falls off the screen of the detector. To fix this we added a gyroscopic system to our camera and lens so that the incident light may hit the system asmuthally at every point on the raster. This in turn will provide a higher quality diffraction pattern for reconstructing in CDI.
Using Ecological Niche Modeling to better understand Pediomelum aromaticum, a threatened Utah plant
Authors: Ian Eggleston, Ashley N Egan. Mentors: Ashley N Egan. Insitution: Utah Valley University. Ecological Niche Modeling (ENM) is a very useful technique that gives us insight into a species’ present and possible future ranges, habitats, and niches. ENM has applications within conservational biology as models can be used to understand the extent to which climate change may impact a species. Additionally, ENM can be useful for prospecting for and propagation of rare plant species. This project will use ENM to create predictive range models for a rare plant species, Pediomelum aromaticum, with the goal of defining an ecological niche, determining impact of climate change, and general conservation of P. aromaticum. Here, we will compare 19 bioclimatic variables using correlation analysis and ecological niche modeling to determine which are the most impactful on the range of P. aromaticum. Additionally, ENMs will be created using the MAXENT algorithm from historical and predicted future climate data. By comparing these models, we can hypothesize as to how climate change may impact P. aromaticum. Finally, models will be compared between predicted climate futures defined as shared socio-economic pathways or SSP. SSP models estimate the impacts of human interactions within the scope of environment, governments, and each other to estimate the impact of varying sets of human interactions as defined by modified global behaviors within humanity and the impacts on global climate change. Different ENM models will be created with different SSP climate models so that we can understand how actions taken by humanity right now may impact the critically imperiled species P. aromaticum.
Effect of a supernova explosion on the mechaincal and thermal stability of orbiting planets
Authors: Alexander Panin, Benjamin Miera. Mentors: Alexander Panin. Insitution: Utah Valley University. Recent searches for extrasolar planets have brought a surprising discovery – almost any star seems to have a planetary system around it. We know that massive stars end their lives in a violent supernova explosion, during which an extremely large amount of energy (~3x10^46 J) is released from the star in a very short time. In this presentation, we analyze the effect of this explosion – primarily the impact of the neutrino flash, the gamma ray flash, and the expanding plasma shell - on the mechanical and thermal stability of an orbiting planet. Our calculations show that a planet's orbit can be significantly disrupted by the momentum of the exploding star shell (depending on the planet's mass and proximity to the host star), but the radiation pressure from the explosion has a much weaker effect. If a star loses too much mass to the expanding shell, any previously stable orbit will become unstable, causing the planets to escape. Additionally, we found that the gamma ray flash and the plasma shell incident on the planet can cause significant heating, while the neutrino flash would have virtually no effect. Also, if a star’s collapse is asymmetric then the star itself can leave the planetary system due to the momentum of the asymmetric neutrino radiation. The sequence of events during a supernova explosion and how they influence such a planet is discussed in the presentation.
Unlocking Well-Being, Workplace Morale, and Employee Retention: A Tech Company's Success Story
Authors: Michaela Thackeray, Cicilee Petersen, Scott Wiltbank, Emma Newman, Enoch Thackeray. Mentors: Matt Draper. Insitution: Utah Valley University. Abstract: Unlocking Well-Being, Workplace Morale, and Employee Retention: A Tech Company’s Success Story This qualitative study, titled "Unlocking Well-Being, Workplace Morale, and Employee Retention: A Tech Company’s Success Story," explores the experiences of employees and leaders at a Utah-based tech company with an unusually low turnover rate. Motivated by the National Institute of Mental Health's call for workplace well-being focus and exacerbated mental health issues during the COVID-19 pandemic, this research investigates the factors contributing to the company's low turnover and high employee satisfaction. The study employs a series of case studies to delve deeply into individual experiences, utilizing phenomenological methods to uncover and describe the depth and breadth of participants' experiences. The research question guiding the study is, “What experiences inform the mental health and well-being of employees and leaders at this low-turnover company individually and collectively?” Qualitative data collection involved interviews with executives, managers, and employees, facilitated through Microsoft Teams software or on-site at the company campus. The data was transcribed, blocked, and analyzed using Giorgi’s Phenomenological Method, a descriptive qualitative approach, supplemented by Nvivo 12 Plus or similar software for a broader thematic examination across participants. The study aims to provide insights into the workplace dynamics that contribute to employee well-being, satisfaction, and retention in the context of a successful tech company. We will present our findings by poster presentation and are open to presenting orally. Thank you for your consideration!
Documenting the Flora of Utah Valley Using Student-written Treatments
Authors: Gideon Bowes. Mentors: Michael Rotter. Insitution: Utah Valley University. Correctly identifying plants in the field can be a daunting task. Making an accurate ID typically requires one to understand a complex lexicon of terminology, possess a level of inherent taxonomic understanding, and have the know-how to traverse complex dichotomous keys and species descriptions. This process often necessitates an array of resources, including large hardbound texts, online references, and stand-alone glossaries of terms. In order to better meet the demands of beginning botanists, we created the Field Manual of the Utah Valley Flora Project. This project includes students taking botany classes at Utah Valley University and tasks them with creating botanical treatments to the plants growing in the Utah County vicinity. The students’ treatments are curated with the objective of providing descriptions that are usable by their peers. Here, we present an example of how treatments are composed using the mustard family (Brassicaceae) and data regarding the efficacy of this project with regard to course learning objectives. The goal of this project is to simplify the identification process by producing a student-written, comprehensive text that is user-friendly and accessible to the beginning botany student.
The Influence of Political Affiliation on Academic Performance: An Examination on How Familial Political Beliefs May Impact a Child’s Educational Outcomes
Authors: Ellery White. Mentors: Yi Yin. Insitution: Utah Valley University. This study will examine the influence that parental political beliefs may have on students’ academic performance. Decades of research have formed empirical links between social- contextual factors and student academic achievement, and this paper will seek to identify whether parental political values play a role in the academic achievement of their children (Lee and Shute 2010; Yamamoto and Holloway 2010). Parental attitudes, behavior, and stylistic approaches to their child’s rearing and education have been extensively studied for how they impact educational outcomes (Pandey and Thapa 2017). This study fulfills the gap in research on the association between parental political beliefs and children’s academic performance. This adds to the academic discourse on the impact parents can have on their children in an academic setting by answering the following questions: How can the political beliefs of parents impact a students’ way of thinking and therefore ability to perform in school? Does the extremity of the parents’ political beliefs make a difference in the outcome of the child’s academic performance? A survey was distributed to a random sample of UVU students which measured their academic performance and the political beliefs of their parents. The statistical program SPSS will be used to conduct a multiple regression analysis to examine the relationship between the independent variable (parents’ political beliefs) and dependent variable (students’ academic performance) to see if there is an association between the two. I hypothesize that students with parents who have strong political beliefs are more likely to be impacted in their academic performance than students with parents who do not have strong political beliefs. Discovering the impact of parental political belief will open several important avenues of inquiry related to educational outcomes of students.
Inexpensive Optical Power Meter
Authors: John Walton, Dallin Durfee. Mentors: Dallin Durfee. Insitution: Utah Valley University. We are developing an inexpensive optical power meter to measure lasers in our lab. In the device the signal from a photodiode is directed through a transimpedance amplifier to provide a voltage proportional to the power of the incident light. We will use an Arduino and a 16 bit ADC to collect the voltage measurement. The Arduino will also control a switch, allowing us to change the gain of the transimpedance amplifier for measurements over a larger range of powers. The Arduino will be programmed with the responsivity curve of the photodiode so that the correct power can be calculated for a given wavelength.
Accelerated Rates of Evolution in hymenopteran DSCAM genes
Authors: Remington R Motte. Mentors: Carl Hjelmen. Insitution: Utah Valley University. Down Syndrome Cell Adhesion Molecule (DSCAM, an immunoglobulin protein) is a protein that is important for neuronal development, especially in invertebrates. While DSCAM is present in other organisms, it has gone through multiple independent duplication events in arthropods. This has resulted in four to six DSCAM exon clusters with thousands of isoforms throughout arthropoda. Due to DSCAM’s role in brain development, I investigated DSCAM1 evolution and its relationship to the evolution of sociality in arthropods. I defined eusocial as having a common nest, cooperative brood care, reproductive castes and generational overlap. Any species that exhibited one or some of these traits I categorized as sub-social, and any that didn’t show these traits were categorized as solitary. Using Bayesian phylogenetic techniques, I compared DSCAM1 phylogenies to mitochondrion phylogenies and found higher rates of evolution in the DSCAM gene within Hymenoptera. The same increased rates were not found with other eusocial species. I then mapped sociality status onto phylogenies to visualize patterns of evolution and estimate ancestral condition of sociality for common ancestors. Increased taxon sampling within cockroaches and termites (Blattodea), as well as including ambrosia beetles (Austroplatypus incompertus), aphids (Pemphigus spyrothecae) and thrips (Kladothrips) could elucidate the relationship between DSCAM evolution and sociality in arthropods.
Altered Estrus Cycles in POMC-deficient Mice
Authors: Nathan Anderson. Mentors: Zoe Thompson. Insitution: Utah Valley University. The pro-opiomelanocortin (POMC) gene is expressed in the hypothalamus and the pituitary gland. The products of this gene are important for food intake and energy expenditure. Mutations in the POMC gene can lead to obesity, excess hunger, and infertility. We are studying a mouse model of POMC deficiency in order to better understand what causes the infertility. In this experiment, we want to study the estrus cycle of mice who have the POMC mutation. The estrus cycle is similar to the menstrual cycle in humans. Specifically, the estrus cycle can be divided into four different stages: estrus, metestrus, diestrus, and proestrus stages. To determine which stage of the cycle the mice are in, we analyze the cells that are present in a vaginal smear, which is collected by a pipet smear technique, and then can be viewed under a microscope. This technique consists of filling a pipet with 0.9% saline solution and flushing this into the vagina of the mice. The cells lining the vagina will be washed off and then collected back into the pipet. These cells will then be added to a slide where they will be looked under a microscope and analyzed based on the number of cornified epithelial cells, leukocytes, and nucleated cells that are present. We have taken pictures of these smears and are analyzing them to determine what stage of the cycle the specific mouse is in at that time. Data was collected over a several week period. Since the POMC gene is absent in the mice being studied, we expect the estrus cycles in the mice to be abnormal. Based on our results, we will continue our research into looking at the specific hormone levels of the mice.
Caffeine's Cognitive Edge: Investigating Memory Enhancement during Non-Optimal Times of the Day
Authors: Greg Avalos. Mentors: Sierra Warner. Insitution: Southern Utah University. The primary objective of this study is to explore caffeine's impact on explicit memory, particularly during the early morning when cognitive performance tends to be at its lowest. We aim to investigate how caffeine modulates attention, memory recall, and consolidation, shedding light on the less-understood psychological effects of caffeine in a real-world context. Participants will be assigned either the caffeine condition or the noncaffeine condition and will be tested on their explicit memory recall using the Craft 21 story recall test. Expected results are that those in the caffeine condition will score higher on the Craft 21 story recall test compared to those who didn't drink caffeine before the study.
Family quality of life partially predicts parenting stress differences between parents with and without children with autism.
Authors: Megara Jensen, Matthew Hatch, Brock Hughes, Madeline Gillies, Spencer Myres, Maddie Blackham, Autumn Gould, Kate Leigh, Nate Lieshman. Mentors: Rebecca A. Lundwall. Insitution: Brigham Young University. Parenting is stressful. Of all children with special needs, parents of children on the autism spectrum report spending the most time at educational, medical, psychological, and behavioral appointments. They also have significant financial expenses. Therefore, we set out to determine if parents on the autism spectrum are more stressed than parents of neurotypical children. We recruited participants using fliers and posts on social media autism support groups and on bulletin boards across campus. The parents (all mothers) had children between 8- and 32-months-old. For this analysis, we divided families into the ASD-sib group if the toddler had an older sibling with autism and the neurotypical group if they had no first-, second-, or third-degree relatives with autism. We asked them to complete surveys using Qualtrics regarding Family Quality of Life, Parenting Daily Hassles, and Parenting Stress measures. Twenty-three parents completed all surveys (n = 7 in the ASD group and n = 16 in the neurotypical group). We performed an ANCOVA with Parenting Stress as the outcome variable, presence of ASD in the family as the grouping variable, and Daily Hassles and Family Quality of Life as predictors. Age was entered as a control variable. We found a trend for the significance for Family Quality of Life predicting Parent Stress (F [17, 23] = 3.80, p = .083, eta2 = .17). No other variables showed a trend for significance. This suggests that parents of children on the autism spectrum are indeed more stressed. Although we need to collect more data, this motivates us in a larger study we are conducting regarding the effects of mindfulness on parental stress levels.
We Are Not Alone: Examining the Impact of a Tween-Teen Diabetes Day Camp
Authors: Heidi Blaylock, Carter Leuba, Eddie Hill, Christina Aguilar, Carla Cox, Aiden Hill. Mentors: Eddie Hill. Insitution: Weber State University. Type 1 diabetes (T1D) is a chronic disease that influences all health aspects. The self-determination theory (SDT) suggests that three psychological needs of competence, autonomy, and relatedness are necessary for motivation to engage in healthy behaviors. Through medical specialty camps, these needs can be met by educating campers on how to manage T1D and realize they are not alone. The volunteer-based, five-day, inaugural REACH teen/tween camp for youth with T1D was held at WSU. Camp activities were engineered around the three basic needs described by the SDT. These needs were promoted by physical and educational activities, and meeting friends. A pre and post evaluation was given. Two measures were significant with autonomy being the greatest, (M=3.93, SD= .75) to post test (M=4.49, SD= .56), with t(25) = -6.258, p= <.001), effect size r = 1.2 Blood glucose levels were collected through an online platform that allowed staff to monitor campers’ levels. The week's average blood glucose level was 152 mg/dL. This study explored the use of SDT to examine the effectiveness of a diabetes camp for youth and hopefully result in better physical and emotional health thus mitigating the risk of complications.
Who Split the Cheese? Search for Paucilactobacillus wasatchensis in a Local Creamery
Authors: Brooklyn Matthews, Andrew Rowley, Michael Salas, Shaun Kader. Mentors: Michele Culumber, Daniel Clark. Insitution: Weber State University. Paucilactobacillus wasatchensis causes significant product loss in the dairy industry by causing gas build-up in packaging, and slit-crack defects in the cheese. By invitation, we tested a cheese manufacturing plant in northern Utah for Plb. wasatchensis in their creamery based on reports of puffed packages of aged cheese. We were allowed to swab several locations in the production area where contamination with Plb. wasatchensis was possible. Swabbed areas included the areas exposed to milk before and after pasteurization, floor drains, the cheese vat, curd cutters, cheddaring table, and packaging environment. Samples of raw milk, fresh curds, and gassy cheese were also collected. Swabs taken from surface samples were vortexed in 1 mL sterile saline solution. The solution was diluted and plated on deMan, Rogosa, and Sharpe agar with 1% ribose (MRS+R) agar. All agar plates were incubated anaerobically for 1 week. Enrichment cultures for Pbl. wasatchensis were also made by inoculating 0.1 mL of the saline rinse from each swab in MRS+R broth, and incubated for 2 days. After growth, were diluted and plated on MRS+R agar. After 1 week of incubation, we selected small (~1 mm), slow-growing colonies that were morphologically similar to Pbl. wasatchensis. The 16S rRNA gene and N-acetyltrasferase gene were amplified using PCR primers specific for Pbl. wasatchensis. Positive Pbl. wasatchensis isolates were found on the handle of the cheese cutter and in the final cheese product showing a gas defect. Our finding suggests that Pbl. wasatchensis is a potential contaminant in the creamery, and though only found in one location, may exist throughout the facility at unculturable levels. Further studies will use molecular techniques to identify Pbl. wasatchensis throughout the facility to identify bacterial DNA instead of live cells, which may more accurately represent the presence of this fastidious organism.
Ecological Dynamics of the Hypersaline Great Salt Lake North Arm
Authors: Amanda Lee, Alex Phillips, Bonnie Baxter, Amy Schmid. Mentors: Bonnie Baxter. Insitution: Westminster College. The Great Salt Lake is home to a massive variety of microorganisms and insights into these populations will aid in understanding the ecosystem. The Union Pacific Railroad’s causeway has divided the lake into two distinct sections and over time caused the North Arm to increase in salinity over the South Arm and gain its hallmark pink color due to restricted freshwater input. Terminal rivers flow into the South Arm while the North Arm’s water evaporates, leaving behind accumulating salty brine, and the two very different waters have nurtured two accordingly distinctive ecosystems. Breaches periodically opened in the causeway allow the waters to mix and provide opportunity for the microbial communities of the two arms to intermingle. In a collaboration between the Great Salt Lake Institute at Westminster University and the Schmid Lab at Duke University, this project focuses on procuring a picture of the North Arm’s microbial diversity and the extent that it adapts to new environments over the four seasons, as well as what happens to the microbes and their nutrient exchange at that breach mixing point. Halophilic archaea and algae comprise the majority of biodiversity in the lake, and we hypothesize that those taxonomic compositions of the North Arm are stable over the different seasons, due to their extremophilic nature. Every season, we have collected water samples from the causeway, breach, and Spiral Jetty to grow and isolate bacterial colonies for DNA extraction and imaging. We also collect biofilm on filters to analyze RNA gene expression and metabolite usage as the environment changes. Over nearly two years of sampling, the hypothesis has been supported and we are seeing stability in community compositions in comparison to the less-salty South Arm. We are still interpreting results from the mixed breach samples, but thus far the microbes appear to be similar to those in the North Arm.
Mountain Haven - Senior Capstone
Authors: Brandon Rojas. Mentors: Kristen Arnold. Insitution: Weber State University. The Mountain Haven building in Salt Lake City, a mixed-use facility, offers a wide range of services, including housing, childcare, and healthcare. The Single Parent Project, a non-profit organization, is working to provide suitable housing solutions for single parents and their children. The primary challenge is creating a secure, private, and healthy living environment that supports the emotional, financial, and mental growth of single parents and their children. To address this challenge, the Mountain Haven building must be designed to meet the unique needs of single-parent families. This includes providing access to quality childcare, flexible work arrangements, and efficient household management solutions. It is also important to foster a sense of community and neighborliness and to ensure that single parents have access to affordable and safe housing in a safe neighborhood (Johnson, 1986). Additionally, the arrangement of the home should be flexible to accommodate both work and childcare responsibilities. The design of the Mountain Haven building should also consider the latest research on daycare centers, healthcare facilities, and interior design. This includes using materials that are free of harmful substances, creating spaces that promote learning and nurture children's development (Monoko, Mukurunge, Bhila, 2021), and using light and color to create a healing environment for parents and children to reduce stress and strengthen the mood, mind, and body. (Khaleghimoghaddam, 2023) By incorporating these principles into its design, the Mountain Haven building can provide single parents and their children with a safe, supportive, and nurturing environment in which to thrive.
Investigating the Utility of Avatars and Actors in Undergraduate Psychology Role-Play Exercises
Authors: Kennedy Parker. Mentors: Melinda Russell Stamp. Insitution: Weber State University. Role-playing is considered one of the most effective teaching strategies for training undergraduate clinical psychology students because it fosters active learning in a supportive and safe environment (Gibbs, 2019; Osborn & Costas, 2013). The literature is replete with studies that document the benefits of role-playing for clinical training. These benefits include the development of active-listening, perspective-taking, empathy, critical thinking, communication, collaboration, problem-solving, and increased enjoyment of course material (Dawood, 2013; Gibbs, 2019; Grose-Fifer, 2017). A challenge associated with classroom role-plays involves student reluctance to participate due to feelings of self-consciousness and anxiety associated with being negatively evaluated (Mallonee, 2018). There is limited research on the effectiveness of different role-play modalities which may include classmates role-playing with one another; as well as actors and virtual avatars role-playing with students. There have been mixed findings in the literature regarding whether students are more comfortable disclosing to virtual avatars or to actors in face-to-face encounters (Rogers et al., 2022; Roster & Chen, 2016). To date, there are no research studies comparing student perceptions of role-plays with virtual avatars to face-to-face interactions with actors in undergraduate psychology classes. For the current study, 60 undergraduate Psychology students were randomly assigned to either role-play with an avatar or an actor. Following the 25-minute role-plays, students completed surveys assessing perceived utility value, self-efficacy, level of anxiety, engagement, and future interest in role-playing. This preliminary study will compare the effectiveness of avatar and actor role-play modalities which will help educators better structure training for undergraduate students in clinical psychology.
Genomic Analysis of Male Reproductive Skew in Bornean and Sumatran Orangutans
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
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.
Assessing Risk Authoritarian Parenting and Adult Coping
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
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.
The Effects of State Anxiety on Face Identification
Authors: Patrick R Davies II. Mentors: Acacia Overono. Insitution: Utah Valley University. While there is a dedicated area of the brain for recognizing faces, the efficacy of recognition tasks can vary depending on the context under which they’re performed. The existing literature is undecided on whether anxiety helps or harms tasks relating to emotional content recognition, and some studies have taken steps into researching memory as an additional layer to these recognition tasks. A preliminary study was performed with 16 participants using virtual reality to study the effects of acute anxiety on the ability to correctly identify faces. Participants played either a brief horror game or a brief virtual sandbox in order to induce a desired emotional state, then were asked to complete a brief paired-face identification paradigm. Initial results show that anxiety strengthens identification of neutral emotionally-valent face pairs. Further results may clarify the relationship between anxiety and face identification processes.
From Struggles to Strength: Strategies, Identity, and Acceptance with the LGBT Community
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
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
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.
Gambel Oak Acorns as a Food Resource in the Great Basin, Colorado Plateau, and Southwest
Authors: Sophia Dodge. Mentors: Alex Greenwald. Insitution: University of Utah. This project seeks to address the understudied presence of Gambel Oak acorns in the archaeological record of the Great Basin, Colorado Plateau, and Southwest regions. While ethnographic data and historical records suggest that Native peoples in this area consumed some Gambel Oak acorns, their recognition in archaeological contexts has been limited. This study aims to assess the viability of methodologies for identifying macrobotanical acorn remains, shedding light on their utilization across different time scales, especially as fallback crops during resource shortages, such as climate shifts. Through experimental methods like burning, parching, and midden simulation we will determine how these methods impact the identifiability of acorns. The research holds significance for our understanding of past human responses to climate change and the ongoing struggle for Indigenous food sovereignty, providing valuable insights into sustainable food sources for the future.
From Self-Critique to Self-Care: Examining the Links Between Perfectionism and Self-Compassion
Authors: Peg Bird, Maria Balaceanu, Grace Carsey, Tiffanee Suhaka, Hunter Mitchell, Ives Hong, Tara Caplin, Ed Wu, John T Jones, Dannelle Larsen-Rife. Mentors: John T Jones. Insitution: Utah Tech University. This study examines the relationship between perfectionism and self-compassion. Perfectionism may be beneficial, but often promotes unrealistically high self-imposed standards, a preoccupation with making mistakes, and a compulsivity toward order, leading to self-criticism and self-loathing. Perfectionism results in persistent feelings of failure, indecision, procrastination, and shame, which negatively impact relationships, work-life satisfaction, and overall well-being (Enns et al., 2001; Frost et al., 1993). Self-compassion is directing warmth and care toward oneself during times of suffering and comprises three core components: self-kindness (offering oneself warmth during adversity), common humanity (acknowledging shared suffering), and mindfulness (approaching the experience of pain with presence and curiosity) (Neff, 2003). Self-compassion is associated with mental health and well-being, including a stable sense of self-worth, increased resilience, life satisfaction, and perspective-taking. Furthermore, self-compassion negatively correlates with anxiety and depression, reduced fear of failure, perfectionism, and self-criticism (Barnard et al., 2011; Neff, 2003; Neff et al., 2006). This correlational study will recruit approximately 100 adult participants to evaluate associations between perfectionism and self-compassion. Participants will complete the Frost Multidimensional Perfectionism Scale and the Self-Compassion Scale (Frost et al., 1990; Neff, 2003). We anticipate a negative correlation between self-compassion and perfectionism, with higher levels of self-compassion corresponding with lower levels of perfectionism. If this prediction is supported by the data, the study’s outcomes will extend existing research on the potentially deleterious effects of perfectionism and pave the way for the development of interventions aimed at improving mental health outcomes among individuals adversely impacted by this trait.
