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.
Cryopreservation: The Chilly Future of Biobanking
Authors: Jared Barrot, Mackenzie Burr, Isaac Packer, Peyton Worley, Delaney Anderson, Jack Davis, Jeffrey Okojie, Ken Dixon. Mentors: Jared Barrott. Insitution: Brigham Young University. In cancer diagnosis, drug testing, and treatment, analysis is done almost exclusively on formalin-fixed paraffin-embedded (FFPE) tissue samples, a process known to cause chemical cross-linking, DNA fragmentation, and degradation. With the push for genetic testing and personalized medicine, cryopreservation of tissue samples has started to gain traction in the research community. We utilized FFPE samples and cryopreserved samples, extracted DNA, and compared the samples using three criteria: DNA purity, quality, and yield. DNA yield, measured on nanograms of DNA to milligrams of tissue basis, demonstrated a five times the yield in cryopreserved samples than in FFPE. DNA purity did not show significant differences between a cryopreserved tissue sample versus a FFPE tissue sample, confirming valid use of FFPE storage methods if purity is the only factor; however, DNA quality was significantly better in cryopreserved tissue samples, with nearly twice the DNA quality number (DQN) than FFPE samples demonstrated, with significant portions of longer base pair DNA fragments present, widening the range of molecular applications of the sample. These cryopreserved tissues provide higher DNA quality, a higher percentage of significantly longer DNA fragments, and increased DNA yield from individual samples, confirming that cryopreservation is a better option than FFPE when it comes to choosing tissue preservation and storage methods. More molecular assays and tests can be run, and smaller samples are necessary when utilizing cryopreservation, proving it to be a better option than the “gold standard” of FFPE, particularly in regards to cancer diagnosis, drug testing, and treatment exploration.
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.
Functional Near-Infrared Spectroscopy and Dementia
Authors: Natalia Rubio, Madison Farrer. Mentors: Christopher Anderson. Insitution: Utah Valley University. Functional Near-Infrared Spectroscopy (fNIRS) is a neuroimaging technique used to monitor brain activity by measuring the changes in blood oxygenation levels, especially when presented with stimuli or given tasks. This is due to the principle that active brain regions require more oxygen, resulting in changes of blood flow and concentrations of hemoglobin. These observable results are achieved by diodes placed on the surface of the scalp that emit near-infrared (NIR) light into the skull. The absorption of this light by the hemoglobin in the brain’s blood vessels is then detected, localizing neural activity. Due to its portability and cost-efficient nature, fNIRS is being widely used across various fields of research and clinical applications whereas other neuroimaging methods might be less feasible or practical. Psychologists and neuroscientists are able to utilize fNIRS to understand how different regions of the brain are involved in various cognitive processes. It has been used in studying conditions like Alzheimer's disease, stroke, traumatic brain injury, autism, schizophrenia, mood disorders, and dementia. In the context of dementia research, fNIRS has emerged as a promising tool . While fNIRS has a low spatial resolution with measurements restricted to the outer cortex of the brain, it enables the study of the progression of dementia by providing real-time data and offering relative tolerance to subject motion. In fact, a neuro-clinic in Provo, Utah (Cognitive FX) has been studying the use of this fNIRS technique on patients with dementia while they perform language tasks. Although no patient data will be used in this study, the use of fNIRS as a technique to learn about the progression of dementia is noteworthy. Therefore, following IRB approval I will perform semi-structured qualitative interviews with two neuro-technicians using fNIRS in this clinic. Items will focus on the strengths and challenges of using fNIRS with dementia patients. Additionally, I will shadow these technicians to gain hands-on experience. Qualitative results will be analyzed and presented. It is anticipated that this research project will raise awareness of the use of fNIRS as a technique in neuroscience as well as its potential to benefit those with dementia.
Combined Inhibition of RAF, MEK, and FAK Attenuates Melanoma Brain Metastases and Prolongs Survival in Preclinical Models
Authors: Ana Paulina Medellin-Alvarez, Jared Almazan, Tursun Turapov, David A. Kircher, Karly A. Stanley, Gennie L. Parkman, MiKaela N. Field, Katie M. Culver, Silvia Coma, Jonathan A. Pachter, Howard Colman, Sheri L. Holmen. Mentors: Sheri Holmen. Insitution: University of Utah. Despite promising results from recent FDA-approved therapies, many advanced melanoma patients develop resistance to both immunotherapy and targeted therapy. A common resistance mechanism to targeted therapy is upregulation of the PI3K/AKT signaling pathway, which has also been shown to promote the development of melanoma brain metastases. Historically, AKT inhibitors have failed in the clinic due to their limited efficacy or intolerable toxicity. Proteomic analysis comparing non-metastatic vs brain metastatic primary tumors in mice revealed focal adhesion kinase (FAK) as an AKT1 specific effector and a potential alternative therapeutic target. FAK is a non-receptor tyrosine kinase that localizes primarily to focal adhesions to regulate cell migration. To determine whether targeting FAK alone or in combination with the RAF/MEK inhibitor avutometinib reduces brain metastases and prolongs survival, we utilized both autochthonous and syngeneic melanoma mouse models. Mice with either subcutaneous tumors or established brain metastases were treated with FAK inhibitor, RAF/MEK inhibitor, or the combination of FAK and RAF/MEK inhibitors. Each cohort was assessed for tumor onset, growth, metastasis, and survival. Our results show that combined RAF/MEK/FAK inhibition significantly delays tumor onset, causes regression of established tumors, prevents the development of brain metastases, promotes the regression of established brain metastases, and prolongs survival. In addition, patient-derived BRAF V600E melanoma xenograft mouse models resistant to the BRAF inhibitor dabrafenib and the MEK inhibitor trametinib, were sensitive to combined RAF/MEK/FAK blockade. The addition of the BRAF inhibitor encorafenib to these models further enhanced the effect on tumor growth. These results support the initiation of a clinical trial evaluating the efficacy of the RAF/MEK inhibitor avutometinib in combination with the FAK inhibitor defactinib in patients with brain metastases from cutaneous melanoma. Additionally, we are assessing non-canonical roles of FAK in modulating the tumor microenvironment to determine whether avutometinib and defactinib also enhance the efficacy of immune checkpoint inhibition in this disease.
Drawing on Memory
Authors: Corin Marsh, Acacia Overono. Mentors: Acacia Overono. Insitution: Utah Valley University. A variety of memorization techniques have been shown to enhance the ability to recall important information. While many of these techniques focus on repetition and retrieval of verbal information, the drawing superiority effect (DSE, Wammes et al., 2016) is a phenomenon where drawing leads to better recall compared to re-writing. The present study investigates the extent of these findings by combining the DSE with retrieval practice. This experiment utilized a within-subjects, single-blind design consisting of 32 undergraduate students ranging in age from 18 to 42. Participants were tasked with learning 20 vocabulary terms through a guided slideshow, then studied terms through; reading definitions (verbal restudy), viewing images of the definitions (visual restudy), writing definitions (verbal retrieval), and drawing definitions from memory (DSE with retrieval). After a brief distractor task, participants were tested on their recall of the definitions. Finally, subjects completed a shortened version of the Vividness of Visual Imagery Questionnaire (VVIQ) and a funnel debrief. Preliminary analyses using a repeated measures ANOVA revealed that re-reading was the study method that resulted in the highest recall scores (M = .57) compared to all other conditions (F (3, 93) = 14.9, p < .001, ηp2 = .324). Further — VVIQ ability showed no significant correlation with participant scores for any of the study methods. These results indicate that re-reading was a more effective study strategy for memorizing vocabulary terms with a short delay when compared to viewing images, writing definitions, and drawing definitions from memory. Future work will examine how longer delays and providing feedback influence may modulate the benefits of re-reading, drawing, and retrieval as study strategies. Keywords: drawing superiority effect, retrieval practice, memory, VVIQ
"Am I a good student?": Examining Motivation Style Influences on Coping Strategies to Perceived Academic Failure and Self-Efficacy
Authors: Broden Lund, John Jones. Mentors: John Jones. Insitution: Utah Tech University. Pursuing higher education credentials involves a significant investment of money, time, and energy. For many, this investment fails to pay off when students abandon their studies prior to graduation. Identifying factors that influence persistence to graduation has thus been the subject of a good deal of past research. The aim of this ongoing study is to explore the interaction between motivation type, responses to failure, and self-efficacy, on persistence among students at different stages of their academic careers. Participants will be 100 college students currently enrolled at a mid-sized university in the United States. Participants will complete measures of academic motivation, coping strategies in response to failure, and self-efficacy. We predict that the further a student progresses the more intrinsically motivated they will tend to be, and that this shift in motivation will be accompanied by increasing reliance on problem-focused coping and increased self-efficacy. Our results have the potential to provide a more nuanced understanding of the role intrinsic motivation plays in student success. Implications for students, parents, teachers, and administrators will also be considered.
Lighting for Different Land Uses: A Case Study in Cedar City
Authors: Sebastian Partida. Mentors: Jamie Spinney. Insitution: Southern Utah University. Lighting levels have an important role in influencing the ambiance and functionality of various land uses. To achieve specified goals while optimizing energy efficiency and sustainability, lighting intensity must be balanced. The purpose of this study was to compare light intensity for different land uses (e.g., residential, commercial, industrial, and recreational). This study measured light intensity (i.e., brightness) for a random sample of different land uses using a digital light meter within Cedar City, UT. GPS coordinates were also acquired in order to map the brightness data. As expected, the results revealed that residential land uses were the darkest, whereas commercial and industrial land uses were the brightest. The findings indicate communities have to maintain a balance between creating a warm and pleasant atmosphere and ensuring appropriate illumination for safety and security purposes. Energy-efficient LED fixtures and smart lighting systems, for example, can provide adjustable and programmable illumination settings that meet both aesthetic and safety requirements.
De novo genome assembly and annotation of Curculio sp. (Coleoptera: Curculionidae) provides insight into diapause evolution
Authors: Daniel Davis, Paul B Frandsen. Mentors: Paul B. Frandsen. Insitution: Brigham Young University. The nut and acorn weevils of the genus Curculio (Coleoptera: Curculionidae) are a diverse group of beetles with a unique life history. A female weevil uses her rostrum (snout) that is about the length of her body to dig into the flesh of a developing hard-shelled seed and lay her eggs inside where they can safely develop into larvae. After the grown larvae exit their seeds, they spend one or more years burrowed in the soil near host trees. During this time they enter diapause, a state of suspended development to minimize the energy that they expend. Studies indicate that a major purpose of this behavior is to align their adult emergence with masting events (large scale seed production every 2-5 years) of their host trees. Between, and even within, Curculio species, there is significant variation in diapause lengths and behaviors (Higaki, 2016). This wide array of adaptive behaviors is a result of the coevolution between these insects and their various hosts. Here, we present a high quality genome of a Curculio species. With this genome, we discuss the genetic and evolutionary factors that have given rise to this unique life history of Curculio and future plans to compare the genomes of multiple Curculio to further unravel this mystery.
Diversity and community in macroinvertebrates of Timpanogos Cave, Utah
Authors: Erika Frandsen. Mentors: C. Riley Nelson. Insitution: Brigham Young University. The Timpanogos Cave System consists of three caves in American Fork, Utah. In 2003, the National Park Service (NPS) commissioned Dr. Riley Nelson and laboratory students to conduct a survey of the diversity and abundance of terrestrial arthropod species found within the caves. Over the two years they sampled in Timpanogos Caves, they identified 55 species of macroinvertebrates in an unpublished report.In the 20 years since the last sampling, many environmental factors could’ve changed in these caves, contributing to an overall decrease in both abundance and biodiversity of fauna. Therefore, we repeated the sampling done by the Nelson lab in 2003-2004 for the duration of May 2023-October 2023 to compare the two time periods’ macroinvertebrate communities.The six taxonomic families found most abundantly in 2003-2004 continue to be the most abundant families found in 2023. Additionally, a new taxon of cave beetle Rhadine sp. not found 20 years ago was discovered early in our sampling of 2023. Despite the increase in visitation over the past 20 years, at this stage in the analysis, the macroinvertebrate community within the caves seems to have almost no loss of diversity. Additionally, the appearance of new taxa indicates that there is still more life and diversity within the caves left to discover.
Low Academic Self-Efficacy Predicts Higher Depression and Anxiety in Students of Color
Authors: Nathaniel Call. Mentors: Chelsea Romney. Insitution: Brigham Young University. New college students may experience stressors like difficult academic work, new social environments, and living on their own for the first time. Students of color may experience additional stressors due to minority stress, experiences of racism, and unfamiliar social contexts. We collected self-reported depression, anxiety, and academic self-efficacy measures from 742 first-year college students. We found that students of color reported higher levels of depression, F(1, 733) = 11.04, p < .001, and anxiety F(1, 734) = 14.91, p < .001, compared to white students. Further, we found that white students reported higher academic self-efficacy, F(1, 742) = 9.97, p = .002, compared to students of color. This suggests that lower confidence in academic work is related to higher depression and anxiety in nonwhite students, r(661) = -.32, p < .001. Our study builds on previous research by providing a possible pathway through which students of color develop more depression and anxiety through lower academic self-efficacy compared to white students.
Social Effects of Bed Nucleus of the Stria Terminalis Corticotropin-releasing Hormone and Tachykinin 2 Neuronal Activation Using Optogenetic Stimulation
Authors: Nicholas Poll. Mentors: Moriel Zelikowsky. Insitution: University of Utah. Social interaction is one of the chief drivers of evolution and natural selection. Animal interactions shape the ecological world and have shaped the world’s evolutionary timeline. Of the many types of animal interactions, one of the most influential to behavior and development is aggression. Many animals' aggressive behaviors and mechanisms are so distinct that their origins can be traced back to specific selective pressures. These pressures range from reproductive competition to predator-prey interactions and have apparent effects on many species’ developments. There are many stressors that can increase aggressive tendencies found in mammals, yet it’s clear that the neural bases that connect these stressors and their behavioral responses are understudied. The targeted brain region in this project is the bed nucleus of the stria terminalis (BNST). The BNST is a neurochemically diverse node of the extended amygdala that has been implicated in mediating stress and sensory information. It anatomically acts as a relay station between a number of different structures including the hypothalamus and amygdala. The BNST has been implicated to have a role in stressor-induced aggressive behaviors; however, the neural mechanisms that connect this region and these behaviors are relatively understudied. Corticotropin-releasing Hormone (CRH) in mammals displays upregulation following the introduction of a stressor and has been found to mediate aggression and anxiety. Similarly, tachykinin-expressing neurons have been shown to have a role in mediating aggression in mammals. While CRH and tachykinin’s link to anxiety and aggression is well supported, it is not clear to what extent it has on BNST. This project aims to provide data to support the role that CRH and Tachykinin 2 (Tac2) in the BNST have in mediating aggression in mice through optogenetic stimulation.
Adverse effects of Nr4a3 full body knockouts on adipose tissue
Authors: Jared Carter. Mentors: Jeff Tessem. Insitution: Brigham Young University. Type 2 diabetes mellitus (T2D) is a chronic condition affecting nearly half a billion people worldwide. Symptoms of T2D include impaired glucose tolerance, decreased insulin secretion and significant weight gain. While the symptoms of T2D are well-documented, the underlying pathology remains unclear. Recent research has indicated the critical role of the nuclear receptor Nr4a3 in the development of glucose intolerance and weight gain. In individuals with T2D, the Nr4a3 promoter is hypermethylated, leading to decreased Nr4a3 expression. Elucidating the role of Nr4a3 in mitochondrial respiration in adipose will help define the mechanism of T2D onset and treatment. I studied mice with full body knockout (KO) for Nr4a3. These mice exhibited T2D-like symptoms, including impaired glucose tolerance, reduced insulin secretion and increased adiposity. I measured mitochondrial respiration in muscle, liver, kidney, and adipose tissue, with impaired respiration only observed in adipose tissue. This impairment in adipose tissue respiration correlated with an increase in the size of all adipose deposits, larger adipocytes, and expanded lipid droplets. Intriguingly, the analysis of electron transport chain and tricarboxylic acid complex proteins revealed no significant differences compared to control samples. Instead, the change in respiration was attributed to a reduction in active DRP1 protein, responsible for mitochondrial fission and maintenance. These findings have important implications for our understanding of T2D and its potential treatment strategies, which will be discussed in more detail.
Feminine versus Freakish: The Silence of the Lambs and TERF Rhetoric
Authors: Kenna Johnson. Mentors: Nicole Dib. Insitution: Southern Utah University. My paper is an interpretative analysis of Thomas Harris’ 1988 novel The Silence of the Lambs as analyzed through the lens of feminist film critic Laura Mulvey’s concept of the masculinization of spectators. In her essay collection Visual and Other Pleasures, Mulvey discusses how cinema, as a traditional medium, has misogynistic, voyeuristic characteristics. Through camera angles and editing, the audience is subconsciously led to identify with the protagonist (who is typically male). As a result, we, the audience, follow his gaze to his object of desire: the woman. This phenomenon she deems the masculinization of spectators. In my paper, I have applied Mulvey’s theory to Harris’ novel and concluded that the masculinization of spectators is, in fact, subverted in The Silence of the Lambs. Here, the audience identifies with Agent Clarice Starling, a young FBI trainee. We follow her gaze to the man she has been tasked with hunting: Jame Gumb, who is referred to colloquially throughout the novel as “Buffalo Bill.” Throughout my paper, I analyze the stark differences in characterization between these two. While Starling is depicted as a pillar of feminine strength, Gumb, a male to female transgender character, is depicted as gaudy and grotesque. In comparing the notable differences in characterization, I determine these characters to serve as each other’s foils. Having been denied as a candidate for gender reassignment surgery, he creates a ‘girl suit’ out of his victims’ skins as an attempt to pass as a woman. Gumb’s atrocities paint the transgender population in a monstrous light; Starling’s actions, conversely, portray her as fiercely independent, and a hero for the feminist cause. Drawing from this analysis, I argue that The Silence of the Lambs is a stark support for the trans-exclusionary radical feminism, or TERF, movement. Through an in-depth analysis of the literary symbols present in the novel in conjunction with the two main characters’ characterization, I determine that TERF rhetoric beats strongly underneath the novel’s surface feminism.
Genetic Mutations in the Genomes of Mother-Offspring Pairs Shows Link Towards Nausea and Vomiting in pregnancy
Authors: Dallin Oyler, Ana Alfaro, Kailee Myxter, Ben Brooks, Amanda Brooks. Mentors: Jessica Pullan. Insitution: Southern Utah University. Nausea and vomiting are common complications that occur in 70% of pregnancies. Hyperemesis Gravidarum (HG) is the most severe form of these symptoms and is estimated to be prevalent in 0.3-2% of pregnancies. Due to the fetal and maternal morbidity associated with HG, identifying the cause and treatment options for these women is a critical task in obstetrics. Research regarding the etiology of HG has been fairly recent and is still ongoing, however, evidence had directed to a positive correlation between increased levels of the serum protein GDF15 and HG symptoms. We hypothesize that polymorphisms in both maternal and fetal DNA plays a role in the upregulated GDF-15 seen in mothers experiencing symptoms of HG during pregnancy. The DNA of 2 mothers and their corresponding children were sequenced and analyzed. The DNA was obtained through buccal swabs from the epithelial cells of the inner cheek, and then purified and ran through PCR. We employed 3 distinct primers that correspond to mutations in the genome that account for the elevated levels of circulating GDF-15 in the mother. As of current, the mother-daughter DNA is still under analysis for single-nucleotide polymorphisms, however recently published literature has suggested results similar to our hypothesis. M. Fejzo et al. shows that upregulated serum GDF-15 is primarily of fetal origin, and that maternal sensitivity to GDF15 increases the risk for developing HG. Additionally, the DNA coding variant GDF15 C211G was shown to elevate the risk of HG
Unlocking the Mechanism Behind Depotentiation: A Cellular Model for Forgetting
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
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.
Going Green in a General Chemistry Teaching Lab: Assessment of Learning Outcomes
Authors: Cooper Bell-Hunley, Ming Yu, Emily Heider. Mentors: Emily Heider. Insitution: Utah Valley University. Green chemistry involves the redesign of chemical processes and products to reduce hazards to the environment and human health. Reconsidering the teaching curriculum with a view to embrace green chemistry can reduce costs in waste disposal and has the potential to improve accessibility. This research involves the redesign of qualitative analysis general chemistry experiment to eliminate the use of teratogenic mercury (Hg) and neurotoxic lead (Pb). Making this change creates a more inclusive laboratory since expectant mothers should not be exposed to mercury and therefore some students did not feel safe completing the previous version of the experiment. With any change in curriculum, it is important to consider the impact on learning outcomes that students can achieve. This research details the assessment of learning outcomes with a quasi-experimental design. Instructors in multiple general chemistry labs selected the qualitative analysis experiment (with or without Hg and Pb) and learning outcomes achieved were assessed following the experiment.
Updated Third Generation Sequencing: Assembly Insights
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
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.
The use of ecological niche modeling to characterize the microhabitat of oak hybrids (Quercus undulata) in Utah
Authors: Cate Bateman, Carson Veazie, . Sydney Sandall. Mentors: Matt Ogburn. Insitution: Southern Utah University. Western Utah is home to two distinct species of oak, Gambel oak (Quercus gambelii) and Dixie live oak (Quercus turbinella), which can hybridize to form an intermediate species that has been named Quercus undulata. In spite of previous research on these shrubs, we are still unsure of how the hybrid has survived in small isolated locations well outside of the range of one parent species (Dixie live oak, which is restricted in Utah to Washington, Kane, and San Juan Counties). Our primary objective was to perform an ecological niche modeling assessment of Q. undulata within the Three Peaks Recreation Area. Our approach included collecting plot-level data to determine abiotic and biotic niche factors correlating with the presence/absence of Q. undulata, including slope, aspect, soil type, soil chemistry, vegetation cover, and other associated woody plant species. Our results have shown that Q. undulata populations have higher concentrations in south-facing slopes, potentially reflecting the climatic preferences of its Dixie live oak parent. Results also showed that both focal species, Q. undulata and Q. gambelii, prefer areas with shallow soil and rocky outcrops. We plan to continue data collection and our analysis of soil type and chemistry. These results will help us to better understand the evolutionary history and ecological requirements of this fascinating native Utah plant.
Temporal Decay of Memory Discrimination: Investigating Mnemonic Similarity Task with Extended Delays
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.
A look at Suicidality Among Various Demographics at Southern Utah University
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.
Contrasting Representations of the Berlin Wall in American and German Museums
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
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.
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.
Examining the Effects of Service on Male-Coded Committees on the Reelection of Female Legislators
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
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.
Participation of Spanish-English Bilingualism in the US Political System: How Does Spanish Affect Voter Perception?
Authors: Alexa Smith. Mentors: Iliana Portaro. Insitution: Southern Utah University. Every day, more and more political ads are popping up in Spanglish or even full-out Spanish on screens across the United States. Whether or not these ads are effective is another story. The research conducted here was based on the hypothesis that in America, after its most recent, tumultuous presidential election cycle, given also that Spanish speakers are on the rise, a candidate’s bilingualism could mean the difference between winning a seat or walking home empty-handed. According to an anonymous online research survey conducted in Salem of Marion County, Oregon, this is only the case when a constituent places importance on a candidate’s language ability. Otherwise, the majority of respondents remained largely indifferent. Additionally, this study determines that more can be done to encourage Latinx individuals to participate in the political system, and it all starts with community outreach. The results of this survey are based on a small, mostly Caucasian sample size, but there is still much to be examined.
Do images of gender conformity affect individual comfort and conformity with gender expression
Authors: Alexis Downey, Kylee Navin, Brice Page, Alyssa Franklin, Hannah Cluff, Julie Johnson Pynn. Mentors: Julie Johnson Pynn. Insitution: Southern Utah University. “Gender expression refers to the way a person expresses their gender identity through appearance, behavior, and interests” (Helgenson, 2020). Previous research has shown that clothing has been used as a form of self-expression and that this expression of self-perception is more important for cisgender women (Strubel and Goswami, 2022). Additionally, previous research has found that conservative beliefs predict generalized prejudice toward gender-nonconforming individuals (Prusaczyk and Hodson, 2020). Felt pressure from peers and the self has been found to relate with greater gender typicality (Jackson et al. 2021), which leads us to believe that images of others may influence comfort and conformity with one’s own gender expression. The purpose of our study is to better understand the effects of appearance and political affiliation on comfort and conformity with gender expression. Participants were exposed to one of two visual manipulations: images of gender-conforming individuals, and images of gender-nonconforming individuals. Participants were asked to complete the Comfort and Conformity with Gender Expression Survey before and after being exposed to the images. We predicted that viewing images of gender non-conforming individuals would decrease participants' comfort and conformity with their gender expression, while viewing images of gender-conforming individuals would increase participants' comfort and conformity with their gender expression. Results will be forthcoming. Gender identity and expression are evolving rapidly, and it is important to examine masculinity and femininity in relation to gender non-conforming individuals rather than just gender-conforming individuals.
Meditation and Survival: Connections Between Humanity and Nature
Authors: Reagan Wexels, Lauren Davis, Mason Peterson, Oliver Swanson, Rebekah Story, Julie Johnson Pynn, . . Mentors: Julie Johnson Pynn. Insitution: Southern Utah University. Environmental identity may affect an individual's pro-environmental behaviors, along with their association with the world around them (Clayton et al., 2021.) This concept demonstrates how people act according to their personality and values in relation to the natural world (Wesolek, 2020.)The degree of connection that an individual feels can be measured by the Connectedness to Nature Scale (Mayer et al., 2004.) The purpose of this study is to better understand the effect of Peter Kahn’s technological nature (2011) on people's connection to nature. We hypothesize that mindfulness meditation, which utilizes technological nature, will increase the connection to nature experienced by the participants in comparison to wilderness survival instruction utilizing technological nature. Research has established a link between mindfulness and an individual's connection to nature (Adventure-Heart et al., 2017.) Results will be forthcoming. The proposed study is important, because many people feel less connected to nature than ever. Understanding how to reconnect with the environment will allow greater access to the benefits of doing so.
Sodium Reduction Policy Response
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.
Frim Patron To Partner: Accomplishments of Museum-Armature Archaeology Relationships
Authors: James Hall. Mentors: Paul Stavast. Insitution: Brigham Young University. As of November 2023 the Utah Statewide Archaeological Society's social media pages have close to 4 thousand followers, which shows that interest in Archaeology. From 1955 to around the mid-90s USAS members contributed greatly to the archaeological research and the protection of archaeological sites and the materials created by those people that had called what is now Utah home. Through the partnership of Universities and Museums they had great success and this poster aims to highlight some of those successes and push for Museums to continue facilitating these opportunities.
The Attitudes Towards Religion Scale (ATR): Development and Evaluation
Authors: Samantha Denbow, Katie Finlinson, Carley Grube, Joseph Johnson, Tanner Dougherty. Mentors: Kirsten L Graham. Insitution: Southern Utah University. Religious affiliation is rapidly declining (Engelman, 2019). Given that religions often perpetuate an in-group out-group dynamic, bidirectional prejudices can be seen between both people who are a part of and people who are not a part of religion (Jackson & Hunsberger, 1999). One explanation for this phenomena of leaving religion and increased prejudice is that there is a shift in attitudes towards religion. Attitudes affect behavior and may explain why people are leaving religion and becoming more prejudiced towards religious and non-religious groups. Our scale Attitudes Towards Religion (ATR) aims to measure attitudes towards religion to better understand why these cultural shifts are happening. We have defined attitudes as “a mostly enduring organization of thoughts, feelings, and behavioral tendencies directed towards objects, groups, events, or symbols” (Breckler, 1984; Hogg & Vaughan, 2005). Little research has been done to determine attitudes as a three part model (affect, cognition, and behavior) when examining religion. The current measures used to examine attitudes towards religion are less defined and fail to address the tripartite model of attitudes by relying more on affective and cognitive components of attitudes (Breckler, 1984). One such scale is called the Astley–Francis Scale of Attitude Towards Theistic Faith, which measures attitudes through affective items on a Likert scale. As demonstrated through this scale and others, many measures are also limited to attitudes of theistic, western religions, rather than encompassing nontheistic religions (Astley et al., 2012; Szydłowski et al., 2021). Attitudes are important to research because they impact daily choices in every individual’s life. Our study sample will be recruited through the Amazon Mechanical Turk survey platform and researchers’ social media pages. We predict our scale will measure attitudes towards religion to further inform current literature concerning religion and religious exit. We will examine reliability in our scale by testing Cronbach's alpha to ensure internal consistency. A small pilot group of 5 undergraduate peers reviewed the items for clarity, readability, and face validity. We then made changes to the items based on the feedback. Because our measure was developed according to a well-established tripart theory of attitude, a confirmatory factor analysis will be used to assess initial factor structure and how well our model fits the data. In addition, we will examine convergent validity by comparing the Astley–Francis Scale of Attitude Towards Theistic Faith with our scale. Discriminant validity will be examined by comparing other non-related scales that measure different constructs with our scale. With this information, further research can be done to understand the correlation between attitudes towards religion and religious participation/exit. The authors for this project are Samantha Denbow, Katie Finlinson, Joseph Johnson, Tanner Dougherty, and Carley Grube. This information will be presented in a poster format.
Lithuania's Quest for Energy Independence from Russia
Authors: Michelle Stanley. Mentors: Baktybek Abdrisaev. Insitution: Utah Valley University. Due to the Russian invasion of Ukraine in 2022, much of Europe has been striving to reduce their dependence on Russian energy. Lithuania, however, began this process 11 years ago when Russia raised the price of Russian gas transported through Gazprom. Lithuanian leadership recognized the potential danger of being dependent on Russia and with the Russian invasion of Ukraine, those concerns proved to be well-founded. Through its history, Lithuania has experienced Russian oppression and has fought for its sovereignty. The history of Lithuania’s energy relationship with Russia from its declared independence from the Soviet Union in March 1990, its complete dependence on Russia for gas, and the process of becoming the first European Union country to become independent from Russian gas in May 2022. This is a case study which shows that: independence from Russian energy removes Russia’s coercive power over that country, the current European energy crisis is the culmination of long-standing European dependence on Russian energy, and that eventually European countries will have to reconcile with Russia. The article will outline three significant periods of time in Lithuania’s energy relationship with Russia: the Lithuania-Soviet Union energy relationship immediately before the fall of the Soviet Union, the process whereby Lithuania has pursued its energy independence from Russia since 1991, and Lithuania’s efforts to achieve full energy independence from Russia following the Russian invasion of Ukraine.
Exploring Ontogenescence: The Impact of Food Availability and Variety on Early-Life Mortality and Development in Brine Shrimp
Authors: Cassandra Nelson, Braden Richards, Grace Van Buren, Fernando Gonzalez, Ian Kirkpatrick, Paul Dunn. Mentors: Paul Dunn. Insitution: Utah Valley University. Many organisms experience a life history pattern called ontogenescence, a high but declining mortality risk during early life. Ontogenescence can have a large effect on a population’s growth by limiting the number of new recruits to the population. Clearly, and yet paradoxically, death before reproductive maturity should be selected against, yet ontogenescence persists across many otherwise dissimilar organisms. Some intriguing hypotheses to explain this pattern have been proposed but have not been thoroughly tested. One of these hypotheses, acquisition of robustness as a function of age, is perhaps the most intuitive. The goal of our current research is to examine the validity of this hypothesis by using brine shrimp (Artemia franciscana) as a model organism.Tracking life-history traits like ontogenescence often requires the researcher to be able to follow an individual throughout its lifespan. In aquatic invertebrates, this means culturing animals individually, which can be quite difficult. Here we report on progress we are making with these culturing methods by testing how food availability and variety affect the early life mortality and development rate of brine shrimp in small-volume culture. Our null hypotheses are that neither of these variables will affect mortality or age to maturity in the animals. Our alternative hypotheses are that increased food availability and variety should lower mortality risk and age to maturity. To test our hypotheses, we hatched brine shrimp cysts in artificial seawater and placed individual artemia into wells of 6-well cell-culture plates filled with artificial seawater. We fed the shrimp one of several food treatments to see how diet affects development and mortality. In our first round of trials, we provided our animals with two different food concentrations (high food vs. low food) of the three food types we evaluated: a unicellular alga (Nannochloropsis), a cyanobacterium (Spirulina), and brewer’s yeast (Saccharomyces cerevisiae). In our second set of trials, we provided the shrimp with less variety in their diet (only two of the three food types). As the artemia developed, we conducted regular water changes and monitored development and mortality. We tracked the fate of the artemia until all individuals had either died during development or reached adulthood. Our food availability trials resulted in no significant difference in either mortality risk during development or age at maturity based on food concentrations. Trials examining the effects of limiting the variety of food types are ongoing.
The Relationship Among Attachment Styles, Couple Satisfaction, and Perceived Stress
Authors: Noah James, Rebekah Hakala, Todd Spencer. Mentors: Todd Spencer. Insitution: Utah Valley University. The Relationship Among Attachment Styles, Couple Satisfaction, and Perceived StressNoah James, Rebekah Hakala, Todd SpencerIntroductionAttachment styles play a pivotal role in romantic relationships. According to existing research, individuals with fearful, dismissive, or preoccupied attachment styles tend to experience elevated stress levels (Candel & Turliuc, 2021; Waring et al., 2019). Conversely, those with secure or preoccupied attachment styles report greater relationship satisfaction (Candel & Turliuc, 2021). By exploring the relationship between attachment styles, stress, and relationship satisfaction we hope to foster healthier relationships and deepen our understanding of the interaction between attachment orientations and emotional well-being (Candel & Turliuc, 2021; Waring et al., 2019).AnalysisThe purpose of the present study is to examine the relationship among attachment styles and couple satisfaction and stress. Our sample consists of 411 married individuals. Participants completed the Perceived Stress Scale - short form (PSS-4; Cohen, Kamarck, & Mermelstein, 1983), The Relationship Questionnaire (RQ; Bartholomew & Horowitz, 1991), and Couple Satisfaction Index (CSI-4; Funk & Rogge, 2000). Results of the one way Anova were significant F (3,407) = 10.48, p=<.001. There was a significant difference in levels of relationship satisfaction among attachment styles. Secure attachment (M=15.66, SD = 2.44), fearful attachment (M=14.09, SD = 3.30), preoccupied (M=15.75, SD = 2.35), and dismissing (M=14.05, SD = 3.54). Results of the Bonferroni Post-hoc analysis indicated a significantly higher levels of couple satisfaction than fearful and dismissing attachment styles (p.<.001). There was no significant difference in level of relationship satisfaction between Secure and preoccupied attachment styles. Additionally, there was a significant difference in levels of perceived stress among attachment styles. Secure attachment (M=11.79, SD = 2.47), fearful attachment (M=13.91, SD = 2.55), preoccupied (M=13.20, SD = 3.35), and dismissing (M=11.81, SD = 3.54). Results of the Bonferroni Post-hoc analysis indicated a significantly lower levels of stress among securely attached compared to fearful and pre-occupied attachment styles (p.<.001). There was no significant difference in level of stress between Secure and dismissing attachment styles. Results provide empirical support that secure attachment styles tend to be beficial for both relationship satisfaction and perceptions of stress. Further, dismissive attachment styles reported similar levels of stress as securely attached participants but had the lowest level of relationship satisfaction.
Cognitive and Emotional Intersection: Investigating the Relationship Between Academic Performance and Depression Among Students
Authors: Alley Fausett, Megan Ritter Martin, Kristin Davenport, Malisa Brooks, Kent Hinkson. Mentors: Kent Hinkson, Malisa Brooks. Insitution: Utah Valley University. Background: University students oftentimes face challenges with well-being and mental health, including depression, anxiety, sleep problems, PTSD, and suicide ideation/behaviors. However, previous research in some areas such as depression and its impact on student’s academic performance has remained generally inconclusive because of the contradictory findings that have often been reported. For example, one study will find a moderate association between grade point average (GPA) and depression, while another will in turn fail to find a significant relationship. Thus, more research is needed beyond simple correlations between GPA and depression to understand possible mechanisms and pathways. The current research hypothesizes that depression symptoms will either not be related or be weakly related to GPA but will be significantly associated with several possible mediating variables such as “turning in assignments late”, “having withdrawn from a class”, and “being placed on academic probation.”Methods: University students (n = 1,359) were recruited to participate in this study from dozens of universities across the United States in 2021. Data was collected anonymously and confidentially through a targeted online survey. Students were compensated with a $10 Amazon gift card for their participation. Zero order correlations were conducted to examine the relationship between variables of interest, which may lead to possible mediating pathways.Results: No statistically significant correlation was observed between depression symptoms and academic performance among students. Yet, several other measures of academic performance beyond GPA were found to have negative relationships with depression including five questions of particular academic activity and items such as withdrawing from class, being placed on academic probation, etc. Further, the strength and significance of the relationship between depression symptoms and these measures of academic performance were stronger and more pronounced in those in their Freshman and Sophomore years. Additionally, the relationships were weaker during their Junior and Senior years, and practically non-existent in graduate programs.Conclusion: In summary, our study contributes to the growing number of often-contradictory studies demonstrating a sometimes-yes, sometimes-no relationship between depression and GPA. However, our study goes beyond this binary comparison to explore other variables of academic performance and found several significant relationships that can help the field better understand the impacts of depression on student’s performance. These findings emphasize the importance of addressing mental health for better academic outcomes for university students. Implementing targeted support systems and interventions within educational institutions could benefit students’ overall well-being and improve academic performance.
The "fly"-logeny of Drosophila Chromosome Evolution
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.
Using Graph Coloring to Optimize Monitoring Electric Power Networks
Authors: Nathan Klundt, Violeta Vasilevska. Mentors: Violeta Vasilevska. Insitution: Utah Valley University. In electrical power networks, phase measurement units (PMUs) are sensors used to monitor the network. However, these PMUs are very costly, hence the electric company are interested in using the minimum number of PMUs that will ensure that they can observe the whole network. This real-life problem is modeled in graph theory as a graph coloring game. Namely, the power domination problem [2, 3] in graph theory is concerned with finding a minimum number of these sensors needed to color (observe) the entire graph (network) according to a set of rules. We consider two variants of this coloring problem. The k-fault-tolerant power domination [3] is asking to find minimum number of PMUs needed to observe (color) the whole network (graph) even when k number of the PMUs are faulty but allows only one PMU to be placed on an electric node (vertex). The other variant, called robust power domination [1], asks the same as fault tolerant power domination, but allows for multiple PMUs to be placed on the same electric node (vertex). In this presentation, we introduce these coloring problems through examples, and provide some theoretical bounds on the minimum number of PMUs needed for various families of graphs for both k-fault-tolerant and robust power domination problems.

Visualizing the impact of the Arab Spring on Women Empowerment in the Middle East region.
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.
The More the Merrier: Building the Surface Brightness Fluctuation Distance Ladder
Authors: Mikaela Cowles, Joseph Jensen. Mentors: Joseph Jensen. Insitution: Utah Valley University. We are developing a newly calibrated distance ladder based on surface brightness fluctuations (SBF) to decrease systematic uncertainties in the current measurement of the Hubble Constant. James Webb Space Telescope (JWST) observations of 14 nearby elliptical galaxies are now being observed to measure a new zero point for SBF distances independent of Cepheids. We have recently acquired 69 images of massive early-type galaxies using the Hubble Space Telescope (HST). These HST distances have doubled the number of galaxy distances measured using SBF and will be combined with past SBF surveys to calculate the Hubble Constant to help resolve the Hubble tension. These distances will be added to the Cosmicflows-4 database to help map the mass distribution in the local universe. This project will continue with the allocation of an additional 123 HST orbits, from which we expect to add ~40 galaxies in 2024.
Interoperability and Artificial Intelligence
Authors: Asher Mitchell, Neil Chilson. Mentors: Neil Chilson. Insitution: Utah State University. With the rapid adoption of Artificial Intelligence marked by the release of OpenAI’s GPT model and a number of similar models, concerns are being raised about the potential for centralization of control over the technology, which could have implications like control of user data, increased political influence, lack of user choice, and several other potential issues.This paper focuses on an alternative to the currently proposed solutions to this threat; creating a separate regulatory agency for the technology, or legislating conformity to specific standards. We focus instead on different interoperability-based solutions that allow end users to tap into the source code, giving them the ability to ensure control of their data and allowing for competition in the AI market.
IBD Support: Mental Health Matters
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.)
Transcriptome analysis to study the effects of drought in tomato
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
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
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.
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?
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.
