BackgroundHigher levels of social media use (SMU) have demonstrated associations with higher levels of self-reported stress. However, the association between SMU and physiological markers of stress, such as heart rate variability (HRV), is less understood. We hypothesize that increased time spent each day on social media will be associated with decreased baseline HRV, but only for individuals who report high rates of stress. We also hypothesize that time spent on social media will be associated with decreased baseline HRV for individuals with higher levels of neuroticism. When considered together, we hypothesize the largest association between SMU and baseline HRV for individuals with higher levels of both stress and neuroticism.MethodsUsing a sample of 165 undergraduate students, we measured baseline heart rate variability with a 3-lead ECG. We determined the average SMU using the Social Media Use Questionnaire (SMUQ). We also ascertained self-reported stress levels using the Depression, Anxiety, and Stress Scale (DASS), and levels of neuroticism using the IPIP NEO Neuroticism Extraversion Openness - PR (IPIP-NEO-120). We will use multivariate regression for our analysis.ResultsResults are undergoing analysis. ConclusionsWhile the use of social media by itself may not have a clear direct association with HRV, it is important to consider the effects of social media use on people with a high emotional state of stress and/or high levels of neuroticism. As public policy continues to be developed for social media, it is important to consider how people with higher tendencies to become stressed and those with higher levels of neuroticism can be affected by social media use if unregulated.

In conversations with Representative Watkins from Utah, I learned that there is interest among policy makers and policy influencers in improving adoption placements in Utah. There is interest in investigating the benefits and costs of prioritizing kinship care, so that better policy solutions can move forward. This project aims to provide research-based information on both benefits and costs of kinship care as well as to propose viable policy solutions that could improve outcomes for children and families touched by adoption.In the United States today, it is unfortunate to say that there are many kids that are living within homes that cannot provide them the adequate resources to succeed in life. Financial instability, substance abuse, and parents with mental health challenges are all strong predictors of being placed in kinship care (Jedwab et al., 2020; Tian et al., 2023). For these reasons, organizations such as Child Protective Services (CPS) and others are trying to find homes for these kids in which they can feel safe and still progress in life. For many countries, including the US, kinship care is at the top of the hierarchy when it comes to placement options (Jedwab et al., 2020). Kinship care is “any living arrangement in which children do not live with either of their parents and are instead cared for by a relative or someone with whom they have had a prior relationship. Many agencies include agencies beyond blood relatives such as god parents, family friends, or anyone else with a strong emotional bond to the child” (Geen, 2004, pg. 132). Kinship care has proven well in many cases because it brings a lot of stability to children (Jedwab et al., 2020; O’Brien, 2012; Hallet et al., 2023; helps them to understand their identity (O’Brien, 2012), and it allows them to stay close to the family and friends network (Clements & Birch, 2023).Although kinship care has many upsides, it also has many downsides, which is why it has been a difficult topic for many people. For example, research has found that many people who are kinship carers tend to be alone and older and in poor health (Geen, 2024; Clements & Birch, 2023; Farmer, 2009; Burke et al., 2023) compared to carers in the foster care systems. This may limit their ability to take care of children and provide them the adequate resources that they need in order to flourish. Multiple researchers recommend that state governmental institutions provide more training and financial support to kinship carers (Jedwab et al., 2023; Burke et al., 2023) so that they can at least have the abilities and resources to adequately take care of kids found in these situations. At the end of the day though, ideally it would be beneficial for precautions to take place and standards to be set forth so that children do not have to be placed in out-of-home placements in the first place (Burke et al., 2023).

BackgroundIntrinsic religiosity is a deeply rooted connection to one's faith. Individuals with high intrinsic religiosity find purpose and meaning through their spiritual connections. Extrinsic religiosity is primarily driven by social or other superficial factors. Individuals with high extrinsic religiosity may be more inclined to participate in religious activities and communities without having a deep connection to their faith. Intrinsic religiosity has demonstrated associations with lower self-reported stress, however, associations between intrinsic/extrinsic religiosity and baseline heart rate variability (HRV), a proxy measure of the parasympathetic nervous system, have not been studied. Such research has the ability to explain how the complex relationship between religiosity and stress affects overall well-being. We hypothesize that higher self-reported stress will be associated with lower baseline HRV, but intrinsic religiosity will serve as a buffer, such that stress will have a weaker influence on baseline HRV among individuals who are more intrinsically religious. We predict that extrinsic religiosity will have no influence on the relationship between stress and HRV. MethodsA survey and biofeedback study were conducted on a sample of 165 college students. We used the Depression, Anxiety, and Stress Scale (DASS) and Intrinsic/Extrinsic Religiosity Scale (IE/R), as well as measured baseline heart rate variability (HRV) using a 3 lead ECG. We will analyze the impacts of stress on HRV across people with varying levels of intrinsic/extrinsic religiosity through a multivariate regression model.ConclusionsReligiosity is not often viewed as a direct contributor to health and wellness, however, when viewed as a protective barrier against stress, intrinsic religiosity could play an important role in an individual’s stress response and wellbeing. In the presence of stressors, we expect intrinsic religiosity to be related to healthier parasympathetic functioning as measured through HRV.

Despite significant strides in global gender equality, women remain underrepresented in leadership roles, prompting investigation into public perceptions of women’s leadership. Our research delves into the often-overlooked aspect of female-to-female interactions and their impact on women's self-perception as leaders. We aim to identify the voices that most influence women's beliefs about their leadership abilities, contributing to the broader discourse on gender parity in leadership. Drawing on historical and cross-cultural perspectives, we theorize that women, historically designated as primary caregivers and reproducers of society, play a pivotal role in shaping individuals' beliefs. This designated role may lead women to internalize societal norms that undervalue their leadership capabilities outside the home. We examine the potential impact of empowered female role models on women's confidence in leadership roles. We employ a lab-in-field experiment conducted in Kuala Lumpur, Malaysia, and Arusha and Dar es Salaam, Tanzania. Participants are assigned to groups with varying gender compositions, engaging in a task where success is dependent upon the leader, followed by a post-treatment survey evaluating their experience, leader, and perceptions of female leadership. Through this experiment, we contribute empirical evidence to the ongoing discussion on gender disparities in leadership and challenge existing theories, providing valuable insights into the complex dynamics that contribute to the confidence gap between men and women in leadership roles. Our preliminary findings from our ongoing research may have implications for strategies aimed at fostering gender equality in leadership, encouraging a more nuanced understanding of the factors influencing women as leaders.

While online technology connects people around the world, norms around privacy, appropriate interactions, and information sharing vary significantly from culture to culture. Thus, we investigate potential issues that can happen when individuals from different cultural backgrounds interact through online platforms such as social media or texting. Our study consists of interviewing participants who have recently relocated to another country. Participants were invited to share instances of how their technology usage differs from that in their country of origin. Through inductive coding, we identified patterns in how cultural differences influence technology interactions. In this presentation, we will discuss the results from the analysis including recommendations for developing tools to enhance intercultural interactions online and reduce barriers in cross-cultural exchanges.

The oil-bearing species, Hyssopus officinalis (hyssop) and Lavandula angustifolia (lavender) are important ecological, ornamental, and agriculturally cultivated plants in the state of Utah, playing a central role in the state’s major essential oils industry, and thus economic climate. However, little is known about the virological agents infecting Utah plant species. A project was initiated to identify the viruses infecting symptomatic H. officinalis and L. angustifolia specimens obtained from Utah. Tissues collected from plants of both species exhibited viral associated symptoms of stunting and chlorosis, while collected hyssop specimens displayed additional leaf curling and mottling. Initial MinION sequencing was conducted on cDNA libraries synthesized from lavender and hyssop samples which were multiplexed with that of other species using the cDNA PCR barcoding kit and chip v 9.4.1. The primary run yielded contigs for a novel single-stranded negative-sense RNA nucleorhabdovirus in both specimens, a sequence closest to tomato yellow leaf curl China virus (TYLCCNV) in hyssop, and an ilarvirus related to tobacco streak virus in lavender. However, additional, exclusive MinION runs consistently failed to yield quality results in attempts to obtain the complete the genomes of these viruses. DNA and RNA extractions were once again performed on hyssop and lavender samples, and RNA from 2020 and 2023 were sent out of lab for RNAseq using the Illumina Novaseq. Once complete genomes are achieved further research will be conducted to characterize these novel viral agents, determine the identity of their associated vectors and calculate host ranges. The results of this project will help to advance the limited virological knowledge of Utah plants as well as that of the nation and world, and aid in developing future scientifically-sound pathogen management strategies.

We compare the atmospheric compositions of WASP-39b and WASP-178b, as well as the different observing modes and analysis techniques for both observations. While both objects are gas giants, WASP-178b’s short-period orbit around its A-type host star leads to an equilibrium temperature more than double that of WASP-39b. WASP-39b was the one of the first exoplanets to be studied by JWST, and subsequently gave astronomers the first insights into JWST’s unprecedented exoplanet characterization capabilities. The data was collected using the NIRSpec PRISM observing mode, which provides broad-wavelength observations typically between 0.5 and 5.5 microns. Our intent was to use the publicly released data files and independently confirm the findings of the Early Release Science team while simultaneously validating our own data analysis pipeline. Our custom methods produced satisfactory results, ultimately yielding a transmission spectra that was consistent with that of the ERS team. Following this, we turned our attention to our second planet, WASP-178b, using data from the Cycle 1 program JWST-GO- 2055 (PI Lothringer). Using the G395H NIRSpec observing mode, which provides narrower wavelength coverage (~3-5 microns) with higher-resolution (R~3000), we constrained atmospheric conditions and molecular abundances, specifically H2O and CO. Though these two gas giants are quite unique, we present the results of each study side-by-side to highlight similarities and differences of both planetary atmospheric composition and the JWST observation modes which provided the data.

New botany students are faced with a long list of confusing terminology used within dense textbooks and dichotomous keys. This can be a challenge to learn all the terminology while learning how to identify plants by their various parts which may also be out of date due to the constant change within the field of Botany. The Field Manual of the Utah Valley Flora is written by students for students which results in a more user-friendly resource for learning that is up to date. Students in select botany classes are assigned a specific genus of plants that are found within the vicinity of Utah County (Utah Valley). Students use Utah Valley University’s herbarium, mapping and imaging software, as well as online databases to write descriptions for each species, creating a dichotomous key, and designing range maps. By allowing students to contribute to this field manual, not only will it be easier to read, but it also encourages engaged learning as well as a great opportunity for students to gain experience in technical writing, research methods, and current knowledge of plant terminology and nomenclature. Using the genus Veronica, I demonstrate the process in writing a full treatment for inclusion in the Field Manual of the Utah Valley Flora. First, I looked for details about each species morphology (such as the habit of the plant and the leaves, stems, roots, and flower details). These details allow me to write individual species descriptions for plants in Utah County. Herbarium records are used to describe the habitat and distribution within the greater Utah Valley Region. Next, I used a camera attached to a dissecting microscope to provide pictures of the plants for aid in identification. Lastly, I present a finished and full treatment for the genus Veronica found in Utah Valley. These plants are often considered weeds, but some have medicinal traits used by indigenous peoples as well as serve as habitat for some butterfly and moth species.

Fetal alcohol spectrum disorder (FASD) is estimated to cost four billion dollars per year in the United States that has a wide range of symptoms including low birth weight, microcephaly, and neurobehavioral problems (Belhorma et al., 2021). Drosophila melanogaster is a prime model organism to study FASD as they have variation in sensitivity to alcohol, metabolic and functional tolerance, and withdrawal to ethanol. We collected wild-type (WT) fly embryos and raised them in a regular diet or an antioxidant supplemented diet (acai or curcumin) both with or without ethanol exposure during development. Adult 4-8 day old fruit flies were starved for 24 hours before the conditioning paradigm. The different conditions included exposure to different odors in either an agar environment (CS-) or agar with sucrose (CS+) environment. After conditioning flies were starved again for 24 hours before testing. Y-mazes were used to test their learning and memory abilities. We hypothesized that flies reared on ethanol with the supplemented diet of antioxidants will show an increase in learning and memory performance compared to the FASD condition of flies raised in normal food without antioxidant supplementation, as flies raised in antioxidant supplemented diets will have less oxidative stress. Performance indices for Y-maze tests were calculated based on published protocols: [# No. of flies choosing (CS+) - # No. of flies choosing (CS-) ]/ Total # of flies that made a choice (Mohandasan et al., 2020).

Snow melt is one of the most important parts of Utah’s water budget and has an impact on the Great Salt Lake (GSL) ecosystem, which hit a historic low point in 2022. One aspect contributing to water availability is an increase in dust on our snowpack which enhances snow melt and causes less water in the GSL basin. Using satellite imagery, we will calculate the increase in energy (radiative forcing) over the snowpack due to dust on snow. In previous research, I used a coarse satellite product from the Moderate Resolution Imaging Spectroradiometer (MODIS) to locate areas of dust hotspots on snow in the mountains surrounding the GSL. This project will use imagery with higher spatial detail (Landsat 8) using the same algorithm to measure radiative forcing over snow due to dust deposition. I will compare this data to the same algorithm using MODIS data to have a better analysis of dust in the snowpack. After performing this analysis I can better understand how spatial detail and acquisition frequency affect our accuracy at detecting radiative forcing due to dust on snow and how it changes our water budget.

Insitution: Utah Valley University. When exposed to stressful situations, the human nervous system reacts with the fight or flight response activation. Physiological indicators of the activation of the fight or flight response include a change in body temperature, increased heart rate, blood pressure, and sweating (Sriram et.al, 2012). There is mounting evidence implicating stress as physiologically and psychologically harmful. For example, recent research has found a correlation between chronic exposure to stress and the development of mental illnesses such as anxiety and depression. Furthermore, chronic stress has the potential to change the anatomy of the brain along the hypothalamic pituitary adrenal axis (HPA), which is an important part of the neuroendocrine system, plays a role in the release of stress hormones, and helps regulate moods, emotions, and sexual behaviorisms (Ramirez, et.al., 2013). As college can be quite stressful, developing healthy coping mechanisms to deal with stress might positively influence the students’ academic performance and it might improve and maintain their psychological and physiological well-being (Skowronek, 2014). Various research studies have been conducted to reveal the therapeutic qualities of music. Music can effectively relieve nervousness, promote mental health, and positively affect students' psychological state (Chi, 2020). Current research on stress-related outcomes shows that music interventions play a significant role in stress reduction on physiological levels (de Witte et. al, 2020).  Preliminary results indicated that physiological responses (including heart rate, electrodermal skin response, and body temperature) to a mathematical calculation task were not impacted by the type of background noise (control, calm music, or upbeat music). Therefore, the current study is while being exposed to various music genre types (Kirschbaum et al., 1993). We hypothesize that calmer music might reduce stress response, while faster and more upbeat music might increase the stress response. The study will employ a between-subject measures design. After obtaining the baseline physiological measures when no music is played, the participant will either be exposed to two segments of relaxation/mediation music or two segments of fast-beat music. While exposed to different music conditions, the physiological response will be used to compare the impact of music genre (calm meditation music versus techno music) as well as practice (music segment 1 versus music segment 2) on the human stress response. Findings on the effects of music manipulation on the human nervous system can be used as additional tools for the management of stress.

Many recent studies suggest that biomarker proteins that are associated with certain diseases were often found in urine samples of the patient. Quantum dots (QDs), a type of nanomaterial, have been investigated in previous studies, revealing their fast response in fluorescent properties when interacting with biomarker proteins. In this study, we examined the impact of QDs’ fluorescent properties in complex solutions by utilizing various concentrations of artificial urine samples. The results of this study provide insight into the possibility of using QDs as an alternative method of disease detection.

Current systems of generating 3D fluorescent images of samples require scanning of a sample or multiple exposures to acquire a series of images. Collecting a 3D fluorescent image in these fashions is timely, ranging from minutes to tens of minutes. This is not ideal for imaging live, dynamic samples that change as time progresses. The use of holographic techniques allows for the collection of a 3D image on the scale of milliseconds, therefore negating motion artifacts. Combining the speed of digital holography with fluorescent imaging will allow for identification of labeled biological components within a sample as well as the ability to view the sample in a 3D space thus offering greater detail and information on the sample. This process is called Holographically Informed Fluorescence Imaging (HIFI). Simulations have been run using MatLab in which a sample is imaged using Phase Shifting Digital Holography. The 3D reconstruction of the image is propagated using Huygens Convolution Method, and then all of the pixels of the image are brought into focus numerically. This image is then overlayed with the fluorescence image obtained. Each pixel of the fluorescent image is propagated to the depth of focus for each pixel within the 3D holographic image and a 3D fluorescent image is obtained. Simulations of this process have proved successful. A proof of principle experiment is currently underway as to prove the effectiveness of this fluorescent imaging method.

The STEM career field has been found to be particularly unwelcoming to women and minorities resulting in attrition of these demographics in STEM degrees and careers.2 To address this problem, the National Science Foundation awarded Utah Valley University a grant to fund undergraduate research opportunities with faculty. This preliminary research project explores the effect of mentored undergraduate research opportunities on student retention and success in the UVU Biology Department. Each year for the last 4 years, 10 students were accepted each year into a research cohort. The following factors are known indicators of student success and retention in the STEM fields: self-efficacy1, effort control4, and teacher immediacy3. These factors were qualitatively measured with reflection questions. Students were surveyed at the end of each academic semester. There are two completed cohorts and data is still being collected on the remaining two cohorts. A coding scheme was developed, and reflection questions were coded to consensus. The Pearson's coefficient was greater than 0.76. The preliminary coding results show themes of positive or very positive effects of the research experience on self-efficacy, effort control, and teacher immediacy. The greatest gains were observed in self-efficacy and teacher immediacy. This preliminary data supports the role of undergraduate research in retaining women and minorities in STEM majors.

Authors: Dallin Zollinger, Lauren Brooks. Mentors: Lauren Brooks. Insitution: Utah Valley University. Antibiotics are one of the most important inventions in recent history, saving countless lives. However, their use has also caused antibiotic resistance to increase in frequency among bacterial populations at an astonishing rate. This increase in frequency will influence our treatment of infections worldwide since previous treatments will no longer be effective, causing many deaths that would once have been preventable. Streptogramins are a class of antibiotics used to treat infections which bacteria have evolved resistance to. This study was focused on the vatA gene, which encodes resistance to streptogramins in Staphylococcus aureus. Samples were collected from various areas on the Utah Valley University campus, the DNA was extracted, and polymerase chain reaction (PCR) specific to the vatA gene was performed. Gel electrophoresis was then performed to visualize the amplicons generated from the PCR to evaluate the presence or absence of the vatA gene. Through this work, we have identified locations where this gene is found.

We are using Surface Brightness Fluctuations (SBF) to measure distances to giant elliptical galaxies using the Hubble Space Telescope (HST) and James Webb Space Telescope (JWST). These distance measurements will be used to better define the Hubble Constant, and hopefully help resolve the Hubble tension crisis in cosmology. Part of SBF requires a knowledge of the colors of the galaxies to be studied in order to account for variations in age and composition of the stars contained within. To this end, we are using PanSTARRS and DECam data to determine the optical g-z color (464 nm-900 nm) values for galaxies from the Virgo and Fornax clusters out to 300 million light years.

Study of mode transitions with an artificially-blown clarinet Isaac Settle, Easton Gray, and Bonnie AndersenAbstractWhile playing the clarinet one might experience what is called a squeak or grunt note. A squeak note is a note that is in a higher register without any change of the keys being pressed. Similarly, a grunt note is a lower shifted note with the same circumstances. Both tend to be undesirable while playing, but often happen when learning how to play the clarinet. A similar occurrence of tonal differences can be controlled intentionally when advanced students enacting the technique called voicing to play the instrument in different registers. This research studied the physical parameters that cause squeak and grunt notes. An airtight box was built to hold the mouthpiece of the clarinet and attached to an air compressor. The effects on mode transitions between registers based on air pressure and where contact is applied on specific parts of the reed of the clarinet were studied. Additionally, a laser vibrometer was used to compare reed vibrations to that of the pitch of the clarinet. This data can help clarinet students as they learn the technique of voicing.

Our research group is working to create a meta analysis of the variables that affect the efficiency of eddy current braking systems. We are making a track to accelerate marbles made from different non-ferromagnetic materials down an incline, through a photogate to get its initial velocity, then through a solenoid. We are testing several metals for the marbles and solenoids driven by alternating current with different frequencies. The marble after passing through the solenoid will have its new velocity recorded, allowing us to determine the deceleration experienced by the marble.
