Non-invasive and cost-effective techniques should be prioritized, especially when dealing with threatened vertebrate fauna. By focusing on cryptic Eastern European species within the genus Emberiza (Passeriformes: Emberizidae), we designed an affordable molecular pipeline (including DNA primers and bioinformatics) integrating DNA barcoding with Nanopore sequencing to address species boundaries and provide conservation information for avifauna diversity. We conducted non-invasive DNA extractions from individual feathers of 192 specimens collected in the Aras River Riparian Corridor (ARRC), an important ecological hotspot in Turkey. By targeting the cytochrome oxidase subunit I (CO1) region, our goal was to differentiate Emberiza taxa and identify potential cryptic lineages while using cutting-edge next-generation sequencing (NGS) of multiplexed specimens with portable Oxford Nanopore Technologies. Our focal study examined boundaries in Emberiza subspecies (E. shoeniclus shoeniclus and E. shoeniclus caspia) with subtle morphological differences, utilizing DNA barcoding and Nanopore sequencing. We obtained 182 Emberiza DNA barcodes. Clustering analysis recovered a paraphyletic assemblage (n=32) and a clade, the latter recovering majority of the barcodes (n=150), separated by at least 8% genetic difference. In both cases, we observed a mixture of barcodes from the nominal subspecies and Caspian subspecies, suggesting that cryptic morphological characteristics are not reflected in genetic separation. Our results also suggest putative cryptic Emberiza species, highlighting the importance of the ARRC for conserving avian diversity. We demonstrate that our pipeline, integrating real-time Nanopore sequencing with non-invasive DNA barcoding, can be used for conservation initiatives (particularly aiding cryptic species identification). This study expands our knowledge of avian diversity and highlights the potential of NGS DNA barcodes as a powerful tool for aiding conservation efforts amidst biodiversity loss.

Sjogren’s Disease (SjD) is an autoimmune disease diagnosed by symptoms of reduced tear and saliva excretion, accumulation of lymphocyte foci in the salivary glands, and the occurrence of antibodies against Ro (SSA), La (SSB), and nuclear proteins. The cause of SjD is unknown, though previous studies have detected the sequence and antigens of Hepatitis Delta Virus (HDV) in the minor salivary gland acinar, ductal, and adipose cells of patients with SjD; without the typical presence of a Hepatitis B coinfection. In this study, murine models were transduced with Adeno-associated virus containing expression cassettes for Luciferase (control), small, large, or a combination of both small and large HDV antigens to evaluate the impact of HDV antigen expression on salivary gland function and SjD autoimmune disease development. After a ten- or four-month period, the models were analyzed. Findings included a significant increase of inflammation for samples expressing both small and large HDV antigens, a significant increase of anti-SSA(La) antibodies in samples expressing the short HDV antigen, and a correlation between increased overall inflammation and decreased overall saliva flow. Performing qPCR methods verified the amount of HDV in the submandibular glands and Illumina sequencing portrayed an increase in glycolysis and beta oxidation metabolism in models with detectible HDV sequence. The models showed significantly increased IgM expression in the HDV exposed murine models, without significant change of other antibodies. Future plans include an ELISA diagnostic assay to verify the antibody levels and further sequencing analysis. With this information we can build a better picture of the direct mechanisms of HDV-mediated changes in salivary gland dysfunction and determine the extent that HDV can inducing systemic SjD symptoms.

Authors: Nadia Mando, Josh Shaeffer, Jared Nielsen. Mentors: Jared Nielsen. Insitution: Brigham Young University. Background: “Feeling the Spirit” is an important experience for many active Latter-Day Saints. Feeling the Spirit is often defined by the presence of positive, even if minor, feelings which are perceived to be interactions with deity. However, some Latter-Day Saints struggle to feel the Spirit which can be distressing to them. Recently, LDS leaders have focused on understanding how depressed individuals might experience “feeling the Spirit” differently.Objective: Our pilot study sought to understand the relationship between depression and the frequency and strength of spiritual experiences.Methods: We used the Depression Anxiety Stress Scale-21 (DASS21) to measure depression. We created two separate measures to inquire how frequently and strongly participants felt the Spirit in the last six months. We also created a task asking participants to read multiple scripture passages and report how strongly they felt the Spirit while reading each passage. Responses to each passage were averaged to create a state measure of feeling the Spirit. We hypothesized that higher scores of depression would predict lower scores on feeling the Spirit for all three measures.Results: We found that scores on depression (M=11.388, SD=7.844) significantly correlated to frequency (M=3.683, SD=0.760, r= -0.352, p<.001) and strength (M=4.004,SD=0.628, r=-0.453, p<.001) of the Spirit. However, depression scores were not significantly correlated with our state measure (M=2.384, SD=0.903, r=-0.192, p=0.078). In our regression models we found that depression is a significant predictor of both frequency (R2= 0.091, F(1,83)=8.347, p=.005, =-0.029, p=.005) and strength (R2=0.158, F(1,83)=15.523, p<.001, = -0.032) of feeling the Spirit but, not of feeling the Spirit during the scripture task (R2=0.003, F(1,83)=0.236, p=0.628, = -0.463).Conclusion: These findings suggest that depression may affect how LDS persons experience their relationship with God. Our findings take a step toward explaining why some individuals may experience difficulty in “feeling the Spirit”. Future studies are necessary to elucidate these preliminary findings.

Authors: Abigail Williams, Kelsie Minga, Abby Baker, Ella Sieg, Olivia Harris. Mentors: Wendy Birmingham. Insitution: Brigham Young University. Background: Research has found positive health benefits in the communication of positive events (capitalization) with others who respond with curiosity and enthusiasm. An expectation is that one’s spouse would respond in such a way. And indeed, if one has a highly supportive spouse this is likely the case. However, not all individuals have a highly supportive spouse and may have a spouse whose behavior is more ambivalent. Such ambivalent, or unpredictable behavior may lead to worse physiological outcomes when sharing good news including increased risk for cardiovascular events. Blood pressure should dip 10-15% overnight (“dipping”). A less than 10% dip is associated with higher cardiovascular disease risk. We looked at capitalization and dipping in ambivalent and supportive couples. Interpersonal Theory asserts that positive or negative behaviors from one spouse can elicit similar responses from the other spouse. Thus we looked at capitalization and dipping for spousal ambivalent behavior, and one’s own ambivalent behavior. Ambivalent behavior, whether one own’s or one’s spouse’s can also impact the quality of the relationship.  Methods: 90 couples were recruited from a local university, social media, and the community. Participants completed measures of marital quality. They were fitted with an ambulatory blood pressure monitor for 24 hours. The monitor took a reading every 30 minutes during the daytime and once an hour overnight. Participants completed a daily diary entry each time the monitor took a reading during the daytime which included questions regarding their present activities (e.g., posture, current emotions, food consumption). Participants returned the equipment the following morning and were compensated.  Results:  Ambivalent behavior was associated with worse relationship quality measured as responsiveness, both in terms of one’s own behavior, and one’s spouse’s behavior. We found no association for systolic blood pressure (SBP) dipping for individuals whose spouse’s behavior was viewed as ambivalent, however diastolic blood (DBP) dipping was in the opposite direction showing ambivalent spousal behavior was associated with healthier dipping. Of interest, when one reported their own behavior as ambivalent when their spouse was sharing good news, their SBP dipping was unhealthy.   Conclusions: Spousal ambivalent behavior seems to be less important than one’s own behavior on SBP dipping. This may be because one is generally aware of their own behavior and understands that such behavior is problematic for the relationship. This awareness, however,  may come with a cost for their health as well as their relationship.

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

Authors: Emma Manley. Mentors: Johnathan Chidester. Insitution: Southern Utah University. This presentation will be about the indescribable magical Studio Ghibli movies. Specifically, I will be analyzing how these movies are great at representing life. From the weird, outstanding world of Chihiro’s ghost town from Spirited Away, all the way down to the simple little Iron town of Princess Mononoke. These movies are amazing, not just for their remarkable art work and lovable characters, but for the relatability and symbolism of these stories. These stories are weird and strange, but so is everyone. We are human. A complex being that is evolving every single day. We have creative minds in all sorts of differing ways, and these movies are great at explaining this; they are complex, imaginative, and life-like. I will not be defining every single Studio Ghibli movie, but I have chosen a few movies I wish to expand on. My first one is The Wind Rises. This movie is based on a true story about Jiro Horikoshi, the designer of the A5M fighter aircraft. This story goes into detail about his life: his failures, his trials, and the hardships he endured. The second one is Spirited Away: this story is Studio Ghibli's most famous work. This is a story of a little girl who gets trapped in a spirit world all alone. Along her journey she makes new friends, discovers new ideas, and is able to discover who she is. The final movie is Princess Mononoke: Princess Mononoke is Studio Ghibli's masterpiece. The young warrior Ashitaka is strucken with a curse and will soon die. This story is about him getting rid of his curse, discovering how to make peace and stop hate.We should know and understand these movies, not because they are just films and that I like them, but because they are innovative and original. With these movies we jump into a creative world that we can make our own. These movies are relatable in every sense because they are just like us: weird, quirky, and just so compelling. We feel a connection to the trials that each character has because in a sense we all have been through something of the same. These movies represent life in a silly way that I wish to know more about. I will expand on the way these movies are made, the theme and writing, and the characters that we relate to.

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.

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

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.

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

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

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

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.
