Authors: Ashley Swensen, Ruth Kerry. Mentors: Ruth Kerry. Insitution: Brigham Young University. The American West has been experiencing severe drought for over 20 years with changes in climate. Also, the population in certain states has greatly increased putting increasing pressure on the limited fresh water supply. While the agricultural sector is the biggest consumer of freshwater, much is also used to irrigate turfgrass lawns in urban residential areas. The EPA has estimated that about 50% of household irrigation water is wasted by temporal and spatial misapplications. Temporal misapplications can be reduced by using smart sprinkler controllers that take into account recent weather when scheduling irrigation timing. This research investigates people’s willingness to implement more efficient watering practices with and without incentives. It also investigates how an average water bill for a quarter acre lot varies between states and between cities within 5 states in the semi-arid west (AZ, CO, ID, NV, UT). Following comparison of average water bills between states and cities, the potential savings from taking advantage of water saving incentives offered by cities is investigated. The research found differences between the genders and aridity zones in terms of the types of incentive that are favored and likelihood of utilizing methods to improve irrigation efficiency. Water bills were the highest in AZ and lowest in ID and UT. The low water bills in ID are likely associated with the greater prevalence of agriculture in that state than the others studied. Most UT cities had incentives for Smart Sprinkler controllers or to xeriscape. However, in other states several cities did not have incentives for installing Smart Sprinkler controllers. We conclude by trying to assess whether incentives or disincentives are more effective at reducing water use by residential customers.

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.

The hippocampus is a brain structure involved in recognition memory and pattern separation, or the ability to disambiguate potentially interfering or overlapping memory representations. The Mnemonic Similarity Task (MST) has been used to assess memory specificity by asking participants to encode a series of objects and later perform a recognition memory test with repeated items (targets), similar but not exact repeats (lures), and novel items (foils). In a single-subject case study, we utilized the MST in evaluating recognition memory over various delays of a subject with anterograde amnesia. Subject MC is a healthy young adult female who underwent a unilateral amygdalohippocampectomy as a treatment for epilepsy. This procedure included the complete removal of her hippocampus in the right hemisphere, which we verified with magnetic resonance imaging. In addition to the MST, we compiled a battery of neuropsychological tests, including the Wide Range Assessment of Memory and Learning (WRAML-3), the Delis-Kaplan Executive Functioning System, and the Wechsler Abbreviated Scale of Intelligence (WASI-II) to more holistically assess MC’s memory deficits. Preliminary analyses showed significantly lower lure discrimination when compared with control subjects, indicating deficits in pattern separation. Further analysis of MC’s MST results are being conducted to evaluate her broader ability for recognition memory.

We focus specially on the full-count 1850-1940 census records which include over 10 million unique spellings in the surname field. We use three steps to create this lexicon. First, we use links across multiple census records for the same individuals and use these links to identify spellings of the same surname. Second, we use data from a large genealogical website to help identify the correct surnames for each person and convert this into training data. Third, we develop a machine-learning approach that uses the frequency of surnames across different record collections to identify a lexicon of correctly-spelled surnames. Our final lexicon of correctly-spelled surnames only includes 500,000 of the 10 million unique found in US census records. We also provide a crosswalk that maps the majority of incorrect surnames into a unique surname in the lexicon.

Modern data show a strong positive relationship between community-level average income and life expectancy in the United States. We compile a dataset including place of residence, lifespan, and a proxy for income for 27 million unique individuals from the 1900-1940 censuses. In contrast to the pattern in modern data, we actually find that individuals living in an enumeration district with the top quartile of our proxy for income experienced shorter lifespans than those living in the bottom quartile. We show that this negative relationship was largest in the 1900 census and slowly shrank over the next four decades showing how this negative relationship evolved to the positive relationship we see today.

As childrens’ minds develop, so does their language, however, the effect of media on language has yet to be firmly established. Our study searched for the effect of screen time on language development, and whether problematic media use (PMU) was a factor in normal or late development of language. Data was gathered from a sample (n=265) of 4 year old children using simple regression for problematic media use predicting language development while controlling for screen time. Although the correlation between screen time and language development has been studied, there is a gap in the literature regarding how PMU may relate to language development.

We examine the effectiveness of federal school nutrition policies and regulations; specifically, the recent transitional targets for sodium reduction announced in 2021. We performed web-scraping to gather over 5 million observations representing every U.S. state and over 2000 school districts and then constructed a weekly average of sodium served in school lunches by district. Using this data, we apply OLS regression with district fixed effects and find that the policy caused a significant, one-time reduction in weekly average sodium of approximately 220 mg. We further explore this result by looking at heterogeneous responses to the policy by political partisanship. We find that there is a significant, partisan response to the transitional targets. Lastly, we consider an adverse effect of sodium reduction by looking at potential sodium substitutes in school lunches. Contrary to expectations, our data shows a statistically significant correlation between decreased sodium levels and decreased sugar levels. To conclude, sodium reduction policies reduce sodium and other harmful nutrients but may be less effective across party lines.

Most often, research has looked at the negative effects of social media on mental health. The purpose of this study is to understand the interactions between social media usage and body image, and if there are any ways that social media has a positive impact on body image. This study surveyed children and youth ages 7-17 to gain insight on their social media use and different aspects of mental health. Social media preoccupation and mindfulness were both significantly correlated with body esteem, and a slightly significant correlation was found between positive social media use and body esteem. These findings suggest that mindfulness around social media usage can help mitigate the negative impact on body esteem that many youth experience. Parents can use these findings to have conversations with their children and teenagers about being mindful with social media use and avoiding preoccupation with it.

Authors: Braden Bringhurst, Michael Ray, Megan Barbier, Ellie Smith. Mentors: Peter Ward. Insitution: Brigham Young University. 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: 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.

Bornean and Sumatran orangutans demonstrate pronounced differences in their social behavior. All orangutans are more solitary than other apes and monkeys, but Bornean orangutans are even less social than their Sumatran counterparts. This contrast is generally attributed to differences in forest productivity between the two islands, as feeding competition is a major cost to social behavior. Variation in sociality between the two species directly impacts male reproductive skew, or the extent to which males can monopolize reproductive success. Sex-biased demographic phenomena such as male reproductive skew can be reconstructed across a lineage’s history by comparing genetic variation across different regions of the genome. Autosomes and the X chromosome are inherited in different proportions, in a population with an equal sex ratio, four autosome copies will be passed down for every three X chromosomes. Deviations in genetic diversity from this expected ratio can be indications of sex biased demographic events. This project is leveraging differential inheritance of chromosomes to explore the role of orangutan socioecology in shaping male reproductive strategies through genomic analysis of reproductive skew across Bornean and Sumatran orangutans.

The 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.

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.

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

Implicit Bias is a form of bias that occurs subconsciously but influences conscious actions. It often occurs as racial bias and in apolitical environments (Gassner, 2014). Research shows those who are more conservative leaning are prone to racial bias (Brown, 2019). This research will broaden our understanding of implicit biases with political preferences taken into account. Using an Implicit Association Test, participants will sort "good" and "bad" words as they sort African-American or European-American faces. Research shows there is a correlation between thought compatibility and speed as connections we subconsciously hold are made faster (West, 2021). We predict those with conservative views will have a higher rate of association between black and bad words than those with progressive views, and those who lean progressive will feel they have more implicit bias when asked. this research will enhance our understanding of political bias and more importantly those who take the test will be given a chance to assess their own biases and be provided some tools to live with bias or seek to combat it. Results are forthcoming.

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.

Insitution: Utah Tech University. This study examines the relationship between perfectionism and self-compassion. Perfectionism may be beneficial, but often promotes unrealistically high self-imposed standards, a preoccupation with making mistakes, and a compulsivity toward order, leading to self-criticism and self-loathing. Perfectionism results in persistent feelings of failure, indecision, procrastination, and shame, which negatively impact relationships, work-life satisfaction, and overall well-being (Enns et al., 2001; Frost et al., 1993). Self-compassion is directing warmth and care toward oneself during times of suffering and comprises three core components: self-kindness (offering oneself warmth during adversity), common humanity (acknowledging shared suffering), and mindfulness (approaching the experience of pain with presence and curiosity) (Neff, 2003). Self-compassion is associated with mental health and well-being, including a stable sense of self-worth, increased resilience, life satisfaction, and perspective-taking. Furthermore, self-compassion negatively correlates with anxiety and depression, reduced fear of failure, perfectionism, and self-criticism (Barnard et al., 2011; Neff, 2003; Neff et al., 2006). This correlational study will recruit approximately 100 adult participants to evaluate associations between perfectionism and self-compassion. Participants will complete the Frost Multidimensional Perfectionism Scale and the Self-Compassion Scale (Frost et al., 1990; Neff, 2003). We anticipate a negative correlation between self-compassion and perfectionism, with higher levels of self-compassion corresponding with lower levels of perfectionism. If this prediction is supported by the data, the study’s outcomes will extend existing research on the potentially deleterious effects of perfectionism and pave the way for the development of interventions aimed at improving mental health outcomes among individuals adversely impacted by this trait.

Every day, more and more political ads are popping up in Spanglish or even full-out Spanish on screens across the United States. Whether or not these ads are effective is another story. The research conducted here was based on the hypothesis that in America, after its most recent, tumultuous presidential election cycle, given also that Spanish speakers are on the rise, a candidate’s bilingualism could mean the difference between winning a seat or walking home empty-handed. According to an anonymous online research survey conducted in Salem of Marion County, Oregon, this is only the case when a constituent places importance on a candidate’s language ability. Otherwise, the majority of respondents remained largely indifferent. Additionally, this study determines that more can be done to encourage Latinx individuals to participate in the political system, and it all starts with community outreach. The results of this survey are based on a small, mostly Caucasian sample size, but there is still much to be examined.

Previous research has shown that clothing has been used as a form of self-expression and that this expression of self-perception is more important for cisgender women (Strubel and Goswami, 2022). Additionally, previous research has found that conservative beliefs predict generalized prejudice toward gender-nonconforming individuals (Prusaczyk and Hodson, 2020). Felt pressure from peers and the self has been found to relate with greater gender typicality (Jackson et al. 2021), which leads us to believe that images of others may influence comfort and conformity with one’s own gender expression. The purpose of our study is to better understand the effects of appearance and political affiliation on comfort and conformity with gender expression. Participants were exposed to one of two visual manipulations: images of gender-conforming individuals, and images of gender-nonconforming individuals. Participants were asked to complete the Comfort and Conformity with Gender Expression Survey before and after being exposed to the images. We predicted that viewing images of gender non-conforming individuals would decrease participants' comfort and conformity with their gender expression, while viewing images of gender-conforming individuals would increase participants' comfort and conformity with their gender expression. Results will be forthcoming. Gender identity and expression are evolving rapidly, and it is important to examine masculinity and femininity in relation to gender non-conforming individuals rather than just gender-conforming individuals.

Environmental identity may affect an individual's pro-environmental behaviors, along with their association with the world around them (Clayton et al., 2021.) This concept demonstrates how people act according to their personality and values in relation to the natural world (Wesolek, 2020.)The degree of connection that an individual feels can be measured by the Connectedness to Nature Scale (Mayer et al., 2004.) The purpose of this study is to better understand the effect of Peter Kahn’s technological nature (2011) on people's connection to nature. We hypothesize that mindfulness meditation, which utilizes technological nature, will increase the connection to nature experienced by the participants in comparison to wilderness survival instruction utilizing technological nature. Research has established a link between mindfulness and an individual's connection to nature (Adventure-Heart et al., 2017.) Results will be forthcoming. The proposed study is important, because many people feel less connected to nature than ever. Understanding how to reconnect with the environment will allow greater access to the benefits of doing so.

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.

As of November 2023 the Utah Statewide Archaeological Society's social media pages have close to 4 thousand followers, which shows that interest in Archaeology. From 1955 to around the mid-90s USAS members contributed greatly to the archaeological research and the protection of archaeological sites and the materials created by those people that had called what is now Utah home. Through the partnership of Universities and Museums they had great success and this poster aims to highlight some of those successes and push for Museums to continue facilitating these opportunities.

Religious affiliation is rapidly declining (Engelman, 2019). Given that religions often perpetuate an in-group out-group dynamic, bidirectional prejudices can be seen between both people who are a part of and people who are not a part of religion (Jackson & Hunsberger, 1999). One explanation for this phenomena of leaving religion and increased prejudice is that there is a shift in attitudes towards religion. Attitudes affect behavior and may explain why people are leaving religion and becoming more prejudiced towards religious and non-religious groups. Our scale Attitudes Towards Religion (ATR) aims to measure attitudes towards religion to better understand why these cultural shifts are happening. We have defined attitudes as “a mostly enduring organization of thoughts, feelings, and behavioral tendencies directed towards objects, groups, events, or symbols” (Breckler, 1984; Hogg & Vaughan, 2005). Little research has been done to determine attitudes as a three part model (affect, cognition, and behavior) when examining religion. The current measures used to examine attitudes towards religion are less defined and fail to address the tripartite model of attitudes by relying more on affective and cognitive components of attitudes (Breckler, 1984). One such scale is called the Astley–Francis Scale of Attitude Towards Theistic Faith, which measures attitudes through affective items on a Likert scale. As demonstrated through this scale and others, many measures are also limited to attitudes of theistic, western religions, rather than encompassing nontheistic religions (Astley et al., 2012; Szydłowski et al., 2021). Attitudes are important to research because they impact daily choices in every individual’s life. Our study sample will be recruited through the Amazon Mechanical Turk survey platform and researchers’ social media pages. We predict our scale will measure attitudes towards religion to further inform current literature concerning religion and religious exit. We will examine reliability in our scale by testing Cronbach's alpha to ensure internal consistency. A small pilot group of 5 undergraduate peers reviewed the items for clarity, readability, and face validity. We then made changes to the items based on the feedback. Because our measure was developed according to a well-established tripart theory of attitude, a confirmatory factor analysis will be used to assess initial factor structure and how well our model fits the data. In addition, we will examine convergent validity by comparing the Astley–Francis Scale of Attitude Towards Theistic Faith with our scale. Discriminant validity will be examined by comparing other non-related scales that measure different constructs with our scale. With this information, further research can be done to understand the correlation between attitudes towards religion and religious participation/exit. The authors for this project are Samantha Denbow, Katie Finlinson, Joseph Johnson, Tanner Dougherty, and Carley Grube. This information will be presented in a poster format.

Countless philosophers throughout the years have approached competition in many ways. One of the core subjects that philosophers have used to discuss competition is that of decision theory. Decision theory, in short, discusses the best things to do. Game theory, a subset of decision theory, discusses the same within the context of games, or in other words, strategy. Both of these subjects have been used to evaluate how best to win games of chance, games of choice, and games in between. I work to explore the concept of making moves to gain information, seeking to learn another person’s moves before you make your own. This subset of moves deserves recognition, especially within the modern eras of competition.

Current methods for the diagnosis of bacterial infections require time consuming cultures. To prevent deaths caused by sepsis, faster methods for bacterial identification and antibiotic susceptibility methods are urgently needed. Necessary to these faster methods is the ability to separate and concentrate bacteria. While techniques such as filtering and centrifugation have been explored for this purpose, we propose an innovative approach. Polydopamine (pDA) is a remarkably adhesive polymer that has been used to create antibacterial and anti-biofouling coatings on medical devices. In this study, however, we show how magnetic nanoparticles (MNPs) coated with pDA can selectively bind and remove specific bacteria from suspensions. For these experiments, pDA- MNPs were added to suspensions of bacteria mixtures and allowed to bind for 10 minutes. The MNP/bacteria mixture was then placed on a holder with a magnet which collected the MNPs on the side of the test tube. Finally, the bacterial supernatant was carefully removed and plated. Capture efficiency of the beads was calculated and it was shown that the pDA-coated MNPs preferentially isolated S. epidermidis from a suspension of both S. epidermidis and E. coli. This approach holds great potential for separating bacteria from clinical samples like urine or blood, enabling faster and more efficient diagnosis of bacterial infections.

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: 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: 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.

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.

In an attempt to combat a growing number of nosocomial infections related to medical devices, many studies have investigated the effect of polydopamine (pDA) coated surfaces on biofilm formation and found them to have antibacterial and anti-adhesive properties. However, we discovered that pDA coated magnetic nanoparticles (MNPs) display strong attractive interactions with many, but not all, species of bacteria. Fe3O4 MNPs were prepared using sodium acetate, ethylene glycol, and iron (III) chloride hexahydrate solutions and characterized by a variety of methods. XRD data confirmed a magnetite pattern characteristic of Fe3O4, then TEM characterization of MNP samples showed successful pDA coating onto iron oxide particles. Bacterial capture efficiencies (CE) by pDA-MNPs for 8 strains of bacteria were measured by optical turbidity and plate counts. We have found that CE is a function of exposure time to and concentration of MNPS; thus some experiments were done with constant exposure time and variable MNP concentration and others were done at variable exposure times and constant MNP concentrations. Additionally, these pDA-MNPs exhibit extremely efficient adhesion to some bacteria such as Staphylococcus epidermidis (S. epidermidis) while being ineffective at capturing some strains of Esherichia coli (E. coli). We propose that such capture ability of pDA-coated MNPs can be employed for detection and identification of bacteria in hospitals and for food science quality control.

Authors: Spenser A Clark. Mentors: Acacia Overono. Insitution: Utah Valley University. 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.

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.

Chronic obstructive pulmonary disorder (COPD) affects an estimated 30 million Americans and is the third leading cause of death worldwide. A recent effort to curb deaths and hospitalizations involves remote patient monitoring (RPM). Of all possible monitoring parameters, spirometry presents itself as potentially accurate and helpful, but the exact effect and its size remain to be described. A systematic literature review is being performed to describe the current state and future opportunities in RPM systems that use remote spirometry for COPD patients. Only studies that specifically mention the use remote spirometry for monitoring COPD patients were included. The databases PubMed, Web of Science, Scopus, and EBSCO were searched in July and August 2023. Studies are being synthesized by tabulating the study sizes and designs, technological parameters, and interesting findings. Twenty-nine studies have been included spanning feasibility and pilot studies as well as one randomized clinical trial. Remote spirometry for COPD patients has generally been shown to be feasible. Many studies present systems in early stages of development that have yet to be tested thoroughly in large trials. It may be necessary to involve remote spirometry in more large-scale trials soon. Future studies could confirm the degree to which spirometry adds helpful information for monitoring COPD patients.

Authors: A. Kalani Brubaker. Mentors: Nathan Crane. Insitution: Brigham Young University. 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.

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.

This presentation will discuss the way that music affects memory retention, memory recall, and how it can influence the memory of moments, moods, and emotions. The Public Broadcasting System produced an educational video about how listening to music boosts learning and memory. Research from Harvard noted that while neuro-imaging a patient, singing will help a patient during recovery with a brain injury or a stroke. This results because the left-brain region is majorly responsible for our speech function. Researchers also noted that because singing takes place in the right hemisphere, recovering stroke, Dementia and Alzheimer’s patients are able to regain their speech through singing and eventually being able to transition back into speaking. Having knowledge of how music affects the brain can help build great study habits and empower people to retain new information, recall old information, and have influence over their and other people’s emotions. This is important because music is around us all of the time, whether it is walking through the grocery store or playing through earbuds while studying, and if it has such power to influence these things, then why not use it to the fullest of its potential?

Authors: James Wade, Chris Paul. Mentors: Nathan Usevitch. Insitution: Brigham Young University. 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).

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.

Evaluating the role of LRRC1 in melanoma growth and metastasisThe development of brain metastases is a critical problem in Utah, regardless of the novel therapies created for melanoma. The melanoma mortality rates in Utah are 31% higher than the national average and the melanoma incidences are 80% higher. To lower these incidences, our research is aimed at investigating targets in melanoma that play a crucial role in brain metastasis and can be identified as therapeutic interventions.LRRC1 is a gene known as Leucine Rich Repeat Containing 1. LRRC1 is involved in early-stage adipocytic differentiation. Altered gene and protein expression of LRRC1 is observed in melanoma potentially due to the vital role LRRC1 plays in adipose stem cells that differentiate by adopting the phenotypic, biochemical, and functional properties of more terminally differentiated cells. To evaluate the effect of LRRC1 on melanoma growth and metastasis, we are using an established autochthonous in vitro and in vivo model of melanoma based on the RCAS/TVA avian retroviral system. The results of this study will have tremendous potential to contribute to the understanding of the genetics of this heterogeneous disease.

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.

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

Reconstructing the diet of extinct animals can help us understand how living species are suited to their environments, which can inform paleoecological and zooarchaeological research as well as modern species conservation. Seasonal variation in animals’ diets can further be used to reconstruct seasonality patterns in the past and understand how animals may vary their diet under future climate change. However, determining the diet of extinct species is challenging, and detecting seasonal changes in diet is even more so. Dental microwear texture analysis (DMTA) can be a tool to solve this problem. DMTA analyzes dental microwear by measuring the pits and scratches on teeth to determine what an animal consumed in the days and weeks before it died. This project examines the DMTA of modern African Bovidae species to determine if seasonal dietary changes can be observed. If a difference can be found in the dental microwear of specimens that died during different seasons, seasonal changes in diet can be inferred. Here, I gathered dental microwear data from 407 specimens across five modern studies and matched the data to the museum specimens’ date of death to determine whether it died in a wet or dry season. The analysis found that four of the Bovidae species examined in our study showed evidence of seasonal diet shifts in their DMTA data. Dental microwear can be useful in determining seasonal diets and season of death for specimens. This method can be applied to extinct Bovidae species to understand ancient ecosystems and the evolution of Bovidae dietary strategies.

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.
