Symbolic dynamics allows for modeling---and designing for---the effects of imperfectly measuring a time series of data, by partitioning into a finite number of possibilities. The resulting time series of discrete symbols is then made especially amenable to information-theoretic methods for understanding its temporal structure and correlation. In particular, as long as the partitioning scheme is generating, the resulting estimations for entropy rate---the rate at which the process creates information---converge to a measure of chaos in the underlying system, a dynamical invariant.However, the entropy rate is not sensitive to what kind of generating partition: colloquially, an instrument must be at least accurate enough, but can be more fine-grained as desired. In contrast, its breakdown into a piece which affects future measurements (“bound”) and a piece which does not (“ephemeral”) depends quite dramatically on the choice of generating partition. We ask, then: is there a canonical partitioning scheme for which the full suite of information measures relate to dynamical invariants?To tackle this, we simulate the well-known tent and logistic maps, sweeping over all two-boundary partitions, calculating the full information anatomies for each. We find that ephemeral and bound information are extremized by the single-boundary coarsest generating partition, suggesting a canonical role for the simplest “good enough” instrument. The remaining multivariate measures, meanwhile, reveal hitherto-unseen structure in the process of imperfect measurement.

The utility of ChatGPT in subspecialty consultation for patients (pts) with metastatic genitourinary (GU) cancer.Ayana Srivastava, Gliceida Galarza Fortuna, Beverly Chigarira, Emre Dal, Chadi Hage Chehade, Georges Gebrael, Arshit Narang, Neeraj Agarwal, Umang Swami, Haoran LiHuntsman Cancer Institute at the University of Utah, Salt Lake City, UT;University of Kansas Cancer Center, Westwood, KSBackground:Cancer management requires a multidisciplinary approach, often requiring medical consultation from subspecialists. With the advent of artificial intelligence (AI) technologies like ChatGPT, it is hypothesized that these tools may help expedite the consultation process. This study aimed to assess the efficacy of ChatGPT in providing guideline-based sub-specialty recommendations for managing pts with metastatic GU cancer.Methods:In this single-institution, IRB-approved, retrospective, proof-of-concept study, pts with metastatic GU cancer over the past 3 years were screened. Those with at least one consultation referral to subspecialty clinics were randomly selected. ChatGPT 3.5 was given the most recent clinic note that triggered sub-specialty consultation. The AI tool was then asked to provide an assessment and plan. Two physicians independently assessed the accuracy of diagnoses made by ChatGPT and subspecialty physicians. The primary outcome was the consistency of ChatGPT recommendations with those of subspecialty physicians. Secondary Outcomes included potential time saved by using ChatGPT and comparison of medical decision-making (MDM) complexity levels between ChatGPT and subspecialty physicians.Results:A total of 39 pts were included. Their primary diagnoses included prostate cancer (51.3%), bladder cancer (23.1%) and kidney cancer (15.4%). The referred subspecialty clinic included cardiology (33.3%), hematology (17.9%), hepatology (2.6 %), hospice (10.3%), neurology (12.8%), pulmonary (15.4 %), and rheumatology (7.7%). The average waiting time for pts to be seen in subspecialty clinics was 44.9 days (SD = 42.4). Of 39 patient’s charts reviewed by ChatGPT, 30/39 (76.9%) had the same diagnosis with consultant sub-specialties. The average diagnoses made by ChatGPT were 8.2, compared with 3.4 made by sub-specialty physicians (p < 0.0001). The accuracy of diagnoses made by ChatGPT was the same, higher, and lower than human physicians in 10 (33.3%), 3 (10%), and 17 (56.7%) cases, respectively. Consistency of treatment plans between ChatGPT and physicians was found in 18 cases (46.2%). ChatGPT recommended additional workup in 32 cases (85.1%). The average number of words written in consultation notes by ChatGPT was 362.7 (SD = 72.9), which was significantly greater than subspecialty physicians (n = 224.7, p < 0.0001).Conclusions:These hypothesis-generating data suggest the potential utility of ChatGPT to assist medical oncologists in managing increasingly complex pts with metastatic cancer. Further studies are needed to validate our findings.

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

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

The ubiquitin-proteasome system (UPS) plays a critical role in cancer by regulating the degradation of key proteins involved in cell cycle control, DNA repair, apoptosis, and signaling pathways, making it a crucial mechanism for maintaining cellular homeostasis and preventingtumor development and progression. The expression levels of F-box ubiquitin E3 ligase, FBXO21, correlates with patient survival in several types of cancer, suggesting a role in tumorgenesis. We have previously shown silencing FBXO21 in acute myeloid leukemia (AML) cell lines and patient samples leads to differentiation, slowed tumor progression, increased chemotherapy sensitivity, and altered cytokine signaling. Further, we found that FBXO21 ubiquitinates p85α, a regulatory part of the phosphoinositide 3-kinase (PI3K) pathway, for degradation resulting in altered PI3K signaling. Although PI3K inhibitors are used in cancertreatment, issues like off-target effects, dose-limiting toxicities, and resistance necessitate further research and development for optimized efficiency and minimal negative effects in targeting the PI3K pathway. To further understand the role of FBXO21 in cancer, we utilized shRNAs targeting FBXO21 in various cancer cell lines to identify the role of FBXO21 in cellular proliferation, apoptosis, and alteration of the PI3K pathway. The PI3K signaling pathway is initiated through p85α binding to the catalytic subunit, p110, leading to downstream AKT and mTOR activation. We found knockdown of FBXO21 stabilizes p85α, leading to dimerization of free p85 and decreased PI3K pathway activation. Therefore, we hypothesize that FBXO21 may function as a novel regulator of PI3K signaling, offering an alternative approach to PI3K inhibitors. Our findings suggest that FBXO21 may represent a novel therapeutic target acrossvarious cancer subtypes to target the overactive PI3K pathway. Targeting FBXO21 may enhance the efficacy of current therapies and provide potential benefits for improving patient outcomes in the treatment of cancer, including but not limited to AML

Unfortunately, our understanding of the mechanisms disrupted by GBM is extremely limited. We are unable to safely manipulate brain cells in live patients, and the complexity of human brain networks are difficult to recapitulate in animals. This study employs brain organoids, derived from induced Pluripotent Stem Cells (iPSCs), to model the impact of GBM on neural activity. Organoid batches, grown under normal conditions and co-cultured with GBM cells, were monitored using microelectrode arrays (MEA) to record power in frequency bands. Over time, drugs influencing neural activity were introduced. Significant behavioral distinctions were observed between control and GBM-cultured organoids. Under Bicuculline and Tetrodotoxin, power in GBM organoids exhibited dramatic changes compared to the minimal difference in control organoids. Conversely, 4-Aminopyridine induced increased high-frequency activity exclusively in control organoids. Correlating power in frequency bands with spike activity, this study provides insight on how brain tumors influence neural networks, furthering disease comprehension to eventually develop effective treatment for patients.

Lynch Syndrome, formerly known as Hereditary Non-Polyposis Colorectal Cancer, is an autosomal dominant condition characterized by non-functional DNA mismatch repair genes, leading to mismatch repair deficiency (dMMR). Individuals with dMMR have an increased risk of developing cancerous tumors with microsatellite instability (MSI). The aim of this study was to investigate significant perturbations in gene expression among different dMMR variants within Lynch Syndrome, specifically focusing on variants in the PMS2, MLH1, and MSH2 loci. We obtained 55 public RNA-seq human colorectal tumor samples with specific germline dMMR mutations and 20 samples of healthy colorectal epithelium from the GENE Expression Omnibus (GEO). These samples were subjected to a robust RNA-seq data preprocessing and analytical workflow, which involved quality control, trimming, read pseudomapping and quantification using Salmon, identification of significant differentially expressed genes using edgeR, and gene ontology enrichment analysis using Camera. Signaling pathway impact analysis (SPIA) was employed to assess gene pathway perturbations. Our results revealed that tumor samples from individuals with germline mutations in the PMS2 MMR gene exhibited transcriptomic profiles indicating upregulation in pathways related to intrinsic and extrinsic prothrombin activation, fibrinolysis, and uPA/uPAR-mediated signaling, in comparison to other tumor and healthy samples. Previous research has established a correlation between these pathways and tumor growth, invasiveness, and metastasis. These findings provide a foundation for further research to explore the interactions between PMS2 and these pathways in influencing tumor development.

An efficient method for preparing C-3 aminated pyrazolo[1,5-a]pyrimidines was developed. The method consisted of treating 3-bromopyrazolo[1,5-a]pyrimidine with a wide range of 1° or 2° alkylamines with CuI (20 mol%), L-proline (40 mol%), and Et 3 N (2 equiv) in DMSO under microwave heating conditions (130 °C, 4 hours). C-3 aminated products were obtained in good to excellent isolated yields (54–90%; ave. yield = 77%), and represents the most broadly applicable, non-palladium-catalyzed amination of 3-bromopyrazolo[1,5-a]pyrimidine ever reported. The coupling worked well for unfunctionalized 1° alkylamines such as butylamine, benzylamine, isopropylamine or cyclohexylamine, and more densely functionalized 1° amines with CH 2 - or CH 2 CH 2 -linked heterocycles were also well tolerated (e.g. pyridine-, indole-, thiophene-, and furan-linked methyl- or ethylamine derivatives). 2° Alkylamines such as morpholine, pyrrolidine, and piperidine also reacted well under these conditions. Heating under conventional oil-bath conditions required a more extended reaction time (40 h), but also gave products in good yield (72-76%) for both 100-mg and gram-scale reactions. A pegylated azide (11-azido-3,6,9-trioxaundecan-1-amine) was also coupled in good yield (65% yield microwave), demonstrating compatibility of this methodology for potential click-type applications. Our method is simple and efficient, and avoids drawbacks associated with alternative methods, including long reaction times, limited substrate scope, and required use of air-sensitive/extremely expensive palladium catalysts and specialized synthetic ligands.

Cachexia is a complex syndrome characterized by severe weight loss and muscle wasting. It is also a prevalent complication in various chronic diseases, including cancer and acquired immunodeficiency syndrome. Recent research has underscored the pivotal role of the gut microbiome in systemic well-being. Furthermore, it has been shown that cancer patients suffering from cachexia have unique bacteria composition in the gut compared to that of non-cachectic patients. In the absence of stool samples, there are a few metabolites in the circulatory system that can be directly linked to gut microbiota. Examples include bile acids, and short chain fatty acids as metabolites produced by specific Phylum. The presence of these gut microbiota derived metabolites (GMDM) in the circulation indicate a compromise in the integrity of tight junctions in the intestines. These results prompted an investigation of GMDM as an indicator of gut permeability. Our hypothesis is that an increased concentration of GMDM in the circulation is linked to gut permeability, leading to the development of cachexia in patients with colorectal cancer.  This literature review provides a comprehensive analysis of the relationship between gut permeability and cachexia, seeking to identify which GMDMs are the most accurate indicators of specific bacteria linked to gut permeability, and subsequently, are accurate projectors of cachexia.  Acetic acid, a short chain fatty acid (SCFA) is a GMDM detected in the plasma of patients with gut permeability. Acetic acid makes up about 60% of the SCFAs produced by a healthy gut flora and 90% of it is produced by the genus Bifidobacterium. Our literature review will cover how closely a measurement of acetic acid and other GMDMs measured in plasma can be linked to gut permeability and to Bifidobacterium levels in the gut. Similarly, Indole is a GMDM produced by Escherichia coli and other indole-producing bacteria. Indole isn’t produced naturally anywhere else in the body. When it is naturally absorbed into the liver through the portal vein, it’s mostly converted into indoxyl sulfate. The heightened presence indole in plasma in sulfate-free forms could indicate that indole is being absorbed through holes in the tight junctions of the intestines, rather than through the portal vein. This information would allow cohorts that have collected plasma samples in the past to measure gut permeability by proxy, even if they’re unable to investigate the gut microbiota and metabolites present from stool samples. These connections found could further help us to use-already collected samples to find accurate biomarkers for early cachexia development in cancer patients. If an oral presentation is unavailable, a poster presentation would be great.

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

Tropomyosin Receptor Kinase (TRK) inhibition has become an effective therapeutic approach for treatment of a variety of cancers including soft tissue sarcoma, pilocytic astrocytoma, non-small cell lung cancers, colorectal cancers, glioblastomas, pediatric gliomas, papillary thyroid cancers, and secretory breast carcinoma. Despite the successful use of first-generation TRK inhibitors Larotrectinib and Entrectinib which have shown significant therapeutic response in patients, acquired resistance to these drugs has emerged and is creating serious barriers to maintaining long-term therapeutic efficacy. A common mechanism for acquired resistance is associated with the emergence of mutations. Hence, mutation-induced drug resistance continues to be a major challenge for both first- and second-generation TRK inhibitors. Here, we present the design of novel macrocyclic 3,5-diaminated pyrazolo[1,5-a] pyrimidine ligands with high potential for combating drug-resistant disease.

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

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

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

Since its founding over a century ago, the American Psychological Association has adopted several distinct roles in its ongoing pursuit of legitimacy, stability, and growth for the field of psychology. Two of its most important roles include the establishment and enforcement of an ethics code and the standardization and development of undergraduate education. These two goals are related; the best way to uphold an ethics code is to ingrain that code into future researchers and practitioners. The APA Guidelines for the Undergraduate Psychology Major 3.0, which lists the APA’s ideal learning objectives for undergraduate programs, attempts to do just that. In its section on ethics training, it places a great degree of responsibility on undergraduate programs to prepare students for a world of bad actors, exploitative systems, and ethical grey areas. To achieve this, the document recognizes that students must develop an ethical skill or proficiency, not just a knowledge of the codes and principles. Unfortunately, Guidelines recommendations for achieving that goal quickly become clouded, as the document wrestles with the various concerns about teaching ethics. Primarily, the Guidelines section on ethics seems conflicted about whether instructors should give students historical examples of psychologists and psychology systems engaging in unethical behavior The Guidelines expresses the concern that presenting students with examples of ethical failures by psychologists will distract students from the learning outcomes or lead them to view the field negatively and abandon it altogether. Accordingly, the APA tentatively recommends that negative examples be shared cautiously, alongside examples of the positive achievements of the field and ethical systems in place. Are the APA’s fears that blunt ethics courses could turn students away from the major valid? Or do the Guidelines recommendations put too little faith in their instructors and students? This study seeks to examine the validity of the APA’s concerns and the efficacy of their recommendations. One hundred and fifty Intro to Psychology students will be divided into three groups. Each group will be instructed in the principles of the APA ethics code using a) no historical examples, b) a balance of negative and positive examples, or c) several negative examples. Participants will then take a survey that measures their ethical proficiency, their memory of the material, and their confidence in the field of psychology. Measurement of ethical proficiency will be adapted from APA measurement tools. We predict that the group instructed with several negative examples, without balancing positive examples, will result in greater measurements of ethical proficiency, better recall, and a slightly lowered level of confidence in the field. We predict this based on the idea that reviewing negative examples in the instructional material will provide students with a specific model of ethical decision-making.

This research project examines evidence of individual identity and personhood among perinates, neonates, and young children in the Tiwanaku culture (Western Bolivia, Chile, Peru, A.D. 500-1100) of the ancient Andes. A multifocal approach is taken in examining the topic, and ethnohistorical and archaeological evidence is examined to create a picture of Tiwanaku conceptions of personhood. Through a comprehensive analysis of burial practices, iconography, and ethnohistorical records, this study sheds light on the nuanced conceptions of personhood and individual identity held within the Tiwanaku culture. By delving into the socio-cultural context and material evidence, this research contributes to a deeper appreciation of the complex beliefs and societal values of this ancient Andean civilization.

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.

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.

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.

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.

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.

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.

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.

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 (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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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
