Over the past two decades, studies have documented a 20% decline in Quaking Aspen (Populus tremuloides) populations in western North America (Worrall et al., 2015; Stanke et al., 2021). This phenomenon has been fittingly characterized Sudden Aspen Decline (SAD), and is an increasingly pressing issue as the role of aspen as an ecologically irreplaceable keystone species impacts the health of the surrounding forests (Singer et al., 2019). SAD has been attributed to the interplay of climate change-driven drought and other biotic and abiotic factors that are less well characterized (Anderegg et al., 2013a). One potential contributor to SAD is biotic pests and pathogens (Marchetti et al., 2011; Anderegg et al., 2013a; Worrall et al., 2015). My study system includes both natural populations of aspen representing a precipitation gradient and a controlled garden experiment. The field experiments span five distinct sites across Utah & Colorado, selected and montintered by the Anderegg lab of the University of Utah. The experimental garden contains approximately 300 tree saplings subjected to various levels of drought stress, managed by the Anderegg lab on the University of Utah campus. Through the integration of both controlled and natural experiments, my research aims to comprehensively evaluate the impact of drought exposure on pathogen abundance and chemical defenses in aspen trees.Over the past two decades, studies have documented a 20% decline in Quaking Aspen (Populus tremuloides) populations in western North America (Worrall et al., 2015; Stanke et al., 2021). This phenomenon has been fittingly characterized Sudden Aspen Decline (SAD), and is an increasingly pressing issue as the role of aspen as an ecologically irreplaceable keystone species impacts the health of the surrounding forests (Singer et al., 2019). SAD has been attributed to the interplay of climate change-driven drought and other biotic and abiotic factors that are less well characterized (Anderegg et al., 2013a). One potential contributor to SAD is biotic pests and pathogens (Marchetti et al., 2011; Anderegg et al., 2013a; Worrall et al., 2015). Recent investigations have indicated a link between SAD and specific microbial diseases, suggesting that the increasing frequency and severity of droughts due to climate change might make aspen more vulnerable to certain pathogens, even though many of the most common pathogens of aspen in general require more abundant water (Aung et al., 2018). For example, the foliar Melamspora fungal pathogens require abundant water and are not frequently observed in drought stressed trees.On the other hand, Cytospora, which causes a devastating canker disease in aspen trunks, occurs at higher frequency in plots of trees suffering damage from drought (Guyon, 1996). Lin et al. (2023) shows changes to phyllospheric microbiome in aspen during drought, but far less is known about the leaves specifically. Could drought lead to an altered microbiome in aspen leaves? If different or possibly opportunistic pathogens are better able to colonize the leaf tissue under drought stress, this may be the case.It’s known that plants with a reduced diversity of microbiomes are more susceptible to pathogens (Zheng et al., 2020), but the there is little understanding how drought may reduce microbial diversity in aspen. Aspen have two main groups of chemical defenses (SPGs and CTs) that occur in relatively high levels in the leaf (Lindroth et al., 2023). It is well established that these defend against insect herbivores and that they come with a trade-off for plant growth (Marchetti et al, 2011). There is some observational evidence that these secondary compounds have an effect on pathogens (Jacoby et al., 2021), but there are few controlled studies on this idea. Additionally, Metlen et al. 2009 describes how trees in North America produce higher rates of these metabolites under wetter conditions, attributed to possible UV protection. However, the impact of additional environmental changes have of on the abundance of these compounds is understudied. Aspen are an ideal system to study forest disease and drought because the genus’ (Populus) genomes are easily sequenced and relatively tractable, aspen generally exhibit rapid vegetative growth, their defensive chemistry is relatively well known, and most importantly, they grow in cloned groves that reduce the genetic variation in experiments (Lindroth et al., 2023, Luquez et al., 2007).

Authors: Braxton Bird. Mentors: Sarah Franklin. Insitution: University of Utah. Heart disease ends the lives of nearly 700,000 people each year and has been the leading cause of death in the United States since 1950. Around this time researchers discovered that some modifications involving our genetic code could be altered to affect gene expression but leaves the DNA intact, which was later termed epigenetics. Today we’ve discovered that these epigenetic modifications, including post translational modifications (PTMS), regulate genes linked to cardiovascular disease. We recently examined the histone lysine methyltransferase SETD7, which is most prominently known for its ability to methylate histone H3K4. SETD7’s expression is upregulated in multiple types of heart disease in both humans and mice and is essential for cardiomyocyte differentiation in embryonic development. In addition to its ability to methylated H3K4, SETD7 has been shown to methylate 8 other histone residues. To further characterize the histone residues methylated by SETD7, we carried out an unbiased analysis of lysine residues methylated by SETD7 using an in vitro methyltransferase assay coupled with tandem mass spectrometry. We hypothesized that SETD7 may modify additional sites than those that have previously been identified. Our analysis determined that SETD7 monomethylates two novel residues on histone H3: lysine 36 (K36) and lysine 122 (K122). These sites of modification were also confirmed by western blotting for site specific antibodies to these methylation marks. Although our understanding of both these residues is limited, we do know that K36 methylation is linked to DNA replication and genomic stability while K122 methylation is downregulated in drug-resistant MCF-7/ADR cancer cells. These two novel methylation sites suggest that this lysine methyltransferase plays a more complex role in regulating epigenetic modifications and gene expression than previously recognized. Although the identification of this new enzymatic activity for SETD7 is important for understanding the dynamic function of methyltransferases, additional studies will be necessary to fully elucidate the role of SETD7 in cardiac physiology and gene regulation.

Agaricomycetidae contains two clades that are cultivated by ants: the lepiotaceous and pterulaceous cultivars. However, there are free-living relatives phylogenetically distributed throughout each cultivar clade. Comparison between the free-living relatives and attine system cultivars may identify the evolutionary differences caused by, or initially enabling, agricultural symbiosis. Our research compares free-living relatives and cultivars through genomic and metabolic analysis. Attines undertake significant cultivar maintenance through the regulation of pathogenic contamination of their fungal “gardens” as well as the provision of specific growth substrates, including insect frass. Noting the apparently specialized substrates cultivars receive from the ants, we conducted a pilot test for a growth media preference between a lepiotaceous cultivar, a pterulaceous cultivar, and a free-living pterulaceous relative. We placed the fungi on regular PDY media and PDY media infused with caterpillar frass, and the cultivars either changed structure or had improved growth on the frass-infused media. Following the pilot test, we will run metabolic assays on the cultivars and free-living relatives on different media types. This may indicate a media preference which gives further insight to the attine-fungal symbiotic relationship opposed to the fungal free-living relatives revealing pieces of the fungi’s evolutionary history. We performed DNA extraction, PCR testing, Sanger sequencing of the ITS region, and then whole genome sequencing on the cultivars and their free-living relatives. Sanger sequencing allowed us to build phylogenetic trees to examine the relationship between the free-living fungi and cultivars. The whole genome sequencing allowed us to use antiSMASH software to generate predicted secondary metabolite clusters in a fungi species that “escaped” cultivation, a cultivar, and a free-living relative. This preliminary data suggests a diversification of fungal secondary metabolites occurs after attine domestication. By looking at fungal metabolic and genomic data, we hope to gain insight into the fungi’s evolutionary history and agricultural symbiosis.

The mushroom body of the Drosophila melanogaster is a structure in the brain that is necessary for learning, but much of how it functions remains unknown. In this model organism, D. melanogaster’s mushroom body neurons, known as Kenyon cells, and input projection neurons have connections that are random and biased—in which some projection neurons connect with Kenyon cells more than others—allowing the fly to potentially prioritize the learning of particular odors. I investigated the functional consequences and characterizations of these biases in order to understand the biological role they play for the fly using a theoretical and experimental approach. With a computational model of the D. melanogaster olfactory system, how biased connectivity to the mushroom body influences its ability to form associations with various odors and distinguish between similar odors was explored. Experimentally, the morphological features of olfactory circuits were characterized by low to high connectivity rates to the mushroom body, allowing us to see the unique features in these circuits that are beyond the different connectivity rates. Through a combination of immunohistochemistry and confocal microscopy, high-quality images were generated of these different neuronal olfactory circuits and their morphological qualities, such as the number and volume of boutons they project to the mushroom body. Altogether, these findings demonstrate how neural connectivities behind learning shape the representation space in D. melanogaster and impact its learning outcomes.

Recent advancements in gene therapy have pushed towards the prevention and treatment of a diverse spectrum of disorders and diseases that are caused by misregulation of gene expression programs and their transcriptional regulators. However, the profoundness of the field means that much of the mechanisms and effects of regulation are unknown and understudied. Here, we explore the limits of flexible exogenous gene expression and its potential use in optimizing efficacy and specificity in gene therapy interventions while minimizing the possible associated risks. This is made possible by exploiting the Tet-On system of inducible transcriptional regulation, which allows the expression of any target gene to be reversibly, specifically, and differentially controlled. In this system, the tetracycline repressor (TetR) binds the tetracycline operator (TetO), impeding transcription of any downstream gene embedded by the researcher; tetracycline dosing causes TetR to adopt a new conformation that removes it from TetO, inducing gene expression on command (Das et al., 2016). Because of the diverse utility of this system, we are in pursuit of developing novel TetR-TetO orthologous pairs that do not interfere with this wild-type circuit and can be used to regulate gene expression in parallel. As a first step to generating TetR-TetO orthologs, we mapped the usage of TetO by TetR in a massively parallel reporter assay (MPRA) by engineering an extensive library of mutant TetOs and quantified the resulting range of TetR regulation through reporter gene expression. From this screen, we identified candidate TetO mutants to direct the evolution of the wild-type TetR towards complementary states to those TetO mutant sequences. Our preliminary findings indicate that the engineering of distinct synthetic expression cassettes based on the TetR-TetO operon is feasible. These novel tools may ultimately allow us to build a synthetic genetic circuit to model regulatory feedback loops that can help discover malfunctions in cell growth, reproduction, and cycling that can arise from genetic disorders and can lead to disease.1.

Attachment is fundamental to human development. The parent-child relationship impacts the physical and mental health of the child, particularly social development. The two attachment dimensions — attachment anxiety and attachment avoidance underlie the caregiver-child relationship in early childhood (Bowlby et al., 1973). Attachment anxiety and avoidance may change or persist throughout the life span. Major life transitions may influence attachment, however, people tend to revert to previous attachment trajectories after experiencing life transition (Fraley et al., 2021). Adverse childhood experiences (ACEs) are linked to attachment insecurity which may have notable outcomes in adult relationships (Ross et al., 2022; Synder et al., 2023). Individuals with attachment avoidance and anxiety may have difficulty maintaining existing connections. People with high attachment anxiety and inadequate social support experience poor health outcomes (Stanton & Campbell. 2014). Lack of social support predict post-traumatic stress and thoughts of suicide (Scoglio et al., 2023). Loneliness and social isolation are associated with insecure attachment (Spence et al., 2020). Loneliness is correlated with poor mental health ratings and symptoms, and even mortality (Holt-Lunstad et al., 2015; Jenkins et al., 2023). This study evaluates early attachment, health, and relationships. Approximately 200 adults will be recruited to complete the Experiences in Close Relationships-Revised questionnaire (Fraley et al., 2011), Adverse Childhood Experience Questionnaire (Felitti et al.,1998), the Social Support Questionnaire-Short Form (SSQ6; Sarason et al. 1987), and the three-Item Loneliness Scale (Russell et al., 1980 ).We expect attachment anxiety and avoidance will be positively correlated with loneliness and negatively correlated with social support, while ACEs moderate these associations. Examining how ACEs may interact with attachment avoidance and anxiety may prompt early intervention to improve the caregiver-child relationship.

My research looks at the multifaceted extent of the lived experiences of Mexican-American women through the eyes of Chicana feminist's scholarships and social media content. The first research question considers the insights presented by Chicana feminists’ scholarship to delve into complex experiences. This will highlight their struggles, identities, and achievements. I aim to root around the fundamental theories and narratives that support the study of Mexican-American women.Second, I will examine the everyday experiences of Mexican-American women, and how it aligns with and/or deviates from the scholarship mentioned above. Through secondary research, I will examine common themes in the scholarship and compare them with the everyday experiences that I previously identified.Thirdly, I will research how contemporary Chicanas interact in formal and informal actions of protest that go against traditional norms and patriarchal systems. My research will focus on the gap between scholarly discourse and activism in real-life norms. I seek to present the different ways in which Mexican-American women delve into their own resilience and resistance in challenging existing obstacles. This qualitative research has three phases: first I will identify and synthesize common themes in Chicana feminist scholarship; second, I will code social media content, using both a priori and in vivo coding methods; third, I will write a thematic analysis of the contemporary Chicana experience. By reviewing these sources and data, I will provide an understanding of the experiences of Mexican-American women, their morale with scholarly discourse, and their roles in continued socio-cultural and political activities. The outcomes of this research hope to have regard for the complications around the Mexican-American female experience and their continuing efforts to challenge and change traditional norms and patriarchy

Authors: Lilliana Rogers. Mentors: Dannelle Larson-Rife. Insitution: Utah Tech University. One in five girls and one in twenty boys are victims of childhood sexual assault in the United States (Crimes, 2012). There is ample research on the effects and treatment of CSA on victims, however, a paucity of research on pedophiles and sexual offenders. In this social policy paper, the effects of childhood sexual abuse (CSA) on victims should use neuroscience research to prevent CSA. Furthermore, attachment in childhood is pertinent in developing healthy adult relationships, however, despite having a secure attachment to parents, children still face adverse effects of CSA in intimacy in adulthood (Barnum & Perrone-McGovern, 2017). Furthermore, adults exposed to CSA face a higher risk for mental health disorders, physical health problems, and substance abuse disorders, compared with adults who have not been exposed to CSA (Herder & Redner, 1991). Four main effects of concern are addressed in CSA victims: intimacy in adulthood, mental health risks, physical health risks, and substance abuse. These main points of concern illustrate the detrimental effects of CSA, and justify the need for change. Survivors are not the root cause of childhood sex abuse; perpetrators of sexual abuse against children are, leaving perpetrators who commit CSA at risk for reoffending. Incarceration is ineffective due to short sentencing and the child has already been sexually abused (Grady et al., 2015). In addition to ineffective reprimands, little research has been conducted on why and how pedophilia occurs. However, the limited research that has been conducted, is promising, but needs further funding and research to investigate the origins of pedophilia, how to treat it and how to prevent it. In addition, current pedophilia prevention efforts are noninclusive, inaccurate, and not targeted toward caregivers (Kenny & Wurtele, 2010; Grady et al., 2015; Finkelhor, 2009). Pedophilia is not addressed and treated, only the aftermath of CSA is. By analyzing these main concerns, we examine three points of intervention by addressing sexual offenders and pedophiles through the ineffectiveness of incarceration, the lack of funded research, neuroscientific research, and inadequate prevention methods. These points of intervention can be implemented and may reduce the risk of CSA so no child ever has to experience childhood sexual assault.

Unveiling the Challenges Faced by Deaf and Disabled Undocumented ImmigrantsThis paper shows the overlooked challenges confronted by a particularly vulnerable group—deaf and disabled undocumented immigrants. The motivation behind this study comes from the need to address the unique hardships experienced by this marginalized population. Our research employs a mixed-methods approach, combining participant observation, policy analysis and comparative analysis. Comprehensively exploring their experiences and shed light on their daily struggles.Our finding show that access to language resources is not just a matter of practicality but a matter of preserving their cognitive abilities and preventing language loss, particularly among young immigrants. We advocate for programs and specific policy changes that can help these individuals and their families with the skills they need to communicate effectively and integrate into society.This research significantly contributes to the fields of immigration studies, disability studies, and language acquisition. It underscores the urgency of allocating resources to address the specific communication needs of deaf and disabled undocumented immigrants, preserving their linguistic development and cognitive abilities.In conclusion, this paper seeks to raise awareness and advocate for more inclusive policies and resources to facilitate language acquisition for this vulnerable population. We look forward to presenting our research at UCUR 2024 and engaging in productive discussions about this pressing issue.

Authors: Avary Fielding. Mentors: John Salmon. Insitution: Brigham Young University. Human-robot co-manipulation is a field of study that explores humans and robots collaboratively moving objects in various applications, including areas such as search and rescue or disaster response. The focus of this particular research is the coordination of a group of 2-3 human participants to maneuver a 55-lb table and execute specific tasks, in order to draw insights on effective strategies for humans-robots teams. Within each group, a leader was equipped with a virtual reality (VR) headset, providing them with a visual representation of the end goal. In contrast, one or multiple followers, who were unable to see the desired final position, had the responsibility of following the leader to complete the task. Data pertaining to forces, torques, and position was recorded for several iterations of 18 unique table movements to investigate group strategies and learning over time. One specific maneuver involving diagonal translation in the transverse plane (xy, with +y being to the left of the leader) became of special interest and led to the formation of two key hypotheses surrounding the evolution of human coordination strategies. First, it was hypothesized that participants would initially approach the task by translating forwards (in the x direction) and then sideways (in the y direction), before potentially optimizing their strategy in subsequent trials. Second, it was anticipated that, after successfully completing the task twice, participants would adapt to a more efficient method, involving direct diagonal translation. This research aims to answer whether the transition from sequential translations to diagonal movement is a learned behavior, developed over time as groups become more adept at the maneuver. Understanding how humans naturally tend to optimize large object manipulation can be invaluable in the realm of human-robot co-manipulation, as it provides a point of reference on which to base robot behavior, ultimately improving performance and efficiency in various co-manipulation scenarios.

The prevailing assumption in academia has been that outstanding researchers would naturally be outstanding teachers. However, this notion began to face scrutiny in the late 1950s and early 1960s (Cruz et al., 2023). The societal upheavals of the 1960s had a profound impact on American colleges and universities, leading to students demanding and obtaining a more significant role in campus life. One notable change was the introduction of student evaluations of teaching, which were virtually non-existent before the 1960s but became standard practice by the late 1970s. In response to these shifts and faculty requests for support to enhance teaching, Centers for Teaching Excellence (CTEs) were born, with the inaugural centers established at the University of Michigan and Michigan State University (Bakutes, 1998; Miller, 2002). This marked the beginning of a nationwide initiative to strengthen teaching in higher education, culminating in the formation of over 1,000 such centers by the mid-1970s and general coverage across the United States by 2020 (Wright, 2023). In today's academic landscape, CTEs play an instrumental, mission-driven role in enhancing learning and teaching. The primary mission of most CTEs is to improve student learning, support faculty, encourage innovation, and support scholarly and creative work (Wright, 2023). While there is a wealth of literature on CTE organization, function, and impact, there is a noticeable gap in knowledge regarding the most frequently utilized programming and services offered by CTEs. In the wake of the COVID-19 pandemic, the educational landscape has undergone significant changes, necessitating a shift in the learning and teaching needs of students and faculty. This research seeks to address this evolving dynamic within Utah by examining the prevalent programming and services provided by CTEs across the state. The findings from this research will provide valuable insights into these changing needs and will inform future programming and strategic directions for CTEs in Utah. Bakutes, A. P. (1998).

Since 2008, Utah Valley University has taught community classes through the Family Life Education curriculum called the "Stronger Families Project". Previous research has demonstrated the importance of evidence-based family life education (FLE) programs in strengthening families (e.g., Myers-Walls et al, 2011). This study investigates the efficacy of the Stronger Families Project (SFP) by employing a pre- and post-test analysis of change for participants enrolled in the program in Spring 2023 and analyzing qualitative satisfaction data.

The Stronger Families Project (SFP) is an established FLE program at Utah Valley University (UVU) that is taught by undergraduate student interns to families in the community. The current study aims to examine the efficacy of SFP among Fall 2023 participants. A pre- and post-program evaluation of survey data from participants enrolled in SFP during the Fall 2023 semester will be used to evaluate changes in communication, problem-solving skills, and general family functioning. Several subscales from the program’s own established evaluation tool (Family Wellness, 2023) and the General Functioning Subscale from the Family Assessment Device (FAD, Epstein, 1983) were used. A total of N = 25 participants completed the pre-program surveys in September 2023 and will be asked to complete post-program surveys in November 2023. Results from the pre- and post-test analysis of change will be presented. Implications for future research and Family Life Education (FLE) programs will be discussed.

Public opinion has largely moved away from traditional notions of marriage and religion, particularly for emerging adults (Gubernskaya, 2010; Pew Research Center, 2019). Data shows 44% of those ages 18-29 believe marriage is obsolete (Helimlich, 2011), and 40% of emerging adults are religiously unaffiliated (Pew Research Center). Emerging adults are more likely to explore diversity in relationships and express more openness to various relationship arrangements such as cohabitation and polyamory (Levine, 2020; Trask & Koivunen, 2007; U.S. Census Bureau, 2020), and many emerging adults may not find the structure and rules of organized religion agreeable with their perspectives and chosen lifestyle (Drewelies et al., 2018). Various reports also show strong connections between relationship health and physical and emotional health (e.g., Kiecolt-Glaser & Newton, 2001; Miller et al., 2013), with some connections between religiosity and health (Weaver et al., 2006), but very little information exists on how relationship and religion trend perspectives affect various aspects of health and well-being. Marital paradigms theory suggests that marriage attitudes are shaped by varying “marital contexts,” including religious beliefs, socioeconomic factors, public opinion, and changes in attitudes and beliefs over time (Willoughby et al., 2013). Thus, current relationship, marriage, and religiosity facets are likely interrelated and likely influence health aspects, perspectives, attitudes, and practices. This study extends the current literature exploring how various relationship and religion perspectives connect with various aspects of well-being (e.g., emotional and physical health, self-esteem, stress, general happiness), and how these connections may differ by demographic factors such as age.

Past research has found positive correlations between childhood abuse and the likelihood of developing eating disorders later in life. Much of the research previously composed primarily focuses on specific categories of abuse, including sexual abuse, emotional abuse, and witnessing domestic violence. Feelings of loneliness are often studied in relation to eating disorder behaviors, specifically binge eating disorder (BED). Scarcely any research delivers studies of former college students with a specific focus on introspection regarding feelings of being unloved. The goal of this research project is to understand the correlation between feeling unloved and neglected with eating disorder behaviors. This UVU IRB-approved study (IRB Protocol #939) will use data from 6,000 randomly selected UVU current and former College of Humanities and Social Science (2014-2021) that were sent an email with a survey link. The survey assessed the past Adverse Childhood Experiences (ACEs) related to feeling loved in childhood and their eating habits. The large sample size of this study will help support any findings in this research. Using former Utah college students in this study creates limitations as they are likely to be higher educated and younger than the general population. The results of this research could be relevant to the treatment of eating disorders, the detection of children at risk of eating disorders, and the consequences of feeling unloved in childhood.

Many groups are interested in potential market indicators because more than 60% of adults in the United States have investments in the stock market. Extreme stock trading volumes can be an important indicator of unusual market events, including those that precede market crashes. Several studies utilized Extreme Value Theory (EVT) and the Generalized Pareto Distribution (GPD) to examine and model the behavior of these extreme volumes. In particular, various estimation techniques are explored within the GPD framework to best fit the stock trading volume data. The goal of this study is to utilize mathematical approaches in economics. Our results have implications in both mathematical and economic fields, providing benefits by enhancing our ability to analyze and prepare for extreme market occurrences.

Protein-ligand docking is a computational method widely used in drug discovery to predict binding affinities of small molecules to target receptors. However, despite its widespread utility, the method has inherent limitations that can lead to false negative and false positive results, affecting its reliability. False positives occur when docking predicts strong binding affinities that experimental evidence does not confirm, while false negatives arise when the method fails to identify potent binders validated in experiments.Various factors contribute to these inaccuracies, including limitations in scoring functions and search algorithms, but a significant issue lies in the neglect of protein dynamics, i.e., receptor flexibility. To address this limitation, flexible docking methods, which partially account for receptor flexibility, have been developed, but they come at a considerable computational cost. In this project, we incorporated molecular dynamics simulations and k-means clustering to improve prediction of binding energies of a series of small molecules to the human dopamine 2 receptor, a crucial therapeutic target for neuropsychiatric disorders.Our findings demonstrate that sampling conformational states through molecular dynamics and clustering, followed by docking to representative clusters, offers a more accurate assessment of binding energies. Remarkably, this enhanced predictive capability is achieved with minimal additional computational expense.

The invasive species Japanese Beetle (Popillia Japonica) poses significant ecological and economic challenges in the United States, with an annual expenditure exceeding $300 million on damage repair and control efforts. The beetle's life cycle predominates as grubs in turf from late August to April, suggesting a strategic window for control interventions. We developed an individual based model of the Japanese Beetle life cycle, utilizing predator-prey models, to demonstrate the effectiveness of various control methods. Our findings would suggest that ideal timing of grub treatments within the diapause stage markedly reduces beetle populations and is a cost-effective control method. The results of this model can inform land management decisions in controlling Japanese Beetles.
