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.

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.

There has been a lot of public debate in recent years when it comes to the topic of guns in the United States. Scholarship on the subject has shown varying opinions on how people believe on gun ownership, along with the subject of carrying firearms in public. A Pew Research study found 46% of people supported concealed carrying in places, while support among gun owners was 67% (Parker et al., 2017). While research has been conducted on concealed carry, research on open carry support and the factors that contribute to it are rather unknown. Within our study, we attempt to see how support for open carry, which is legal in most places in the U.S., is affected based on who is doing the open carrying of firearms. Particularly controversial political and racial groups. Within our model we randomly assign survey respondents to either our control question to gauge their support for open carry, or one of four vignettes we have designed to see if exposure to the treatment causes a change in how support for open carry will change. Our results have important implications pertaining to attitudinal (in)stability on core civil liberties within the United States.

How do place-based identities influence American’s attitudes towards perpetrators of politically motivated violence? Through the implementation of a pre-registered conjoint experiment, I seek to answer this question. Ideally, and under normative circumstances, punishment of politically motivated violence should be applied to perpetrators with considerations only towards what/who was targeted in the act and the severity of the violence committed. In the U.S. however, evaluations of guilt are determined through the trial of peers, leaving room for the influence of in-group and out-group biases to appear in the judgement of perpetrators according to the suggestions of Social Identity Theory. As such, biases arise that cloud human judgement based on preconceived attitudes towards various group identities that influence our opinions when judging other individuals. One’s sense of place, or how strongly they identify themselves with their locality and its’ culture, is one of these powerful group social identities that establishes a salient “in-group” persona to other locals, while influencing attitudes towards various “out-groups” of people not from that place. Holding constant other considerations pertinent to acts of politically motivated violence, Americans more harshly evaluate perpetrators of violence from geographic communities other than their own. To judge the relative weight that these place-based identities hold towards the judgement of political violence perpetrators, evaluators were presented with perpetrators with randomly assigned personal characteristics (e.g., where they are from) and varied features of the violent act (e.g., how severe the act was, what/who was targeted), and asked to determine the level of punishment or mercy to be assigned to each perpetrator. I found that perpetrator place characteristics indeed influences the evaluator’s excusal of political violence, however when weighted against the features of the act, the nature of the act matters much more for evaluations on average. These findings can be interpreted as normatively negative, given that an evaluator’s place identity appears to reflect in-group out-group biases that affect the assignment of punishment to a crime. However, the disproportionate effect of the violent act’s target and severity are normatively encouraging.

The social desirability bias is a well-documented and well-studied phenomenon in the social sciences, but it has only been in relatively recent literature that experimentalists have begun to study the effects treatments have on the manner in which the social desirability bias is reflected in social behavior. The aim of this study is to test the effects of perceived privacy influences the way people answer this question: "What is the aim of politics?" This study seeks to replicate findings in other research that has delved into the relationship between perceived privacy and social desirability. Another significant area of interest is how neurodivergent identity, especially autism, fits into the relationship. With this study, we can better understand how social desirability affects political discourse as well as provide insights into the neurodivergent mind and how it relates to politics.

This paper expands on a citizen-candidate model of electoral competition under both plurality rule and ranked choice voting. The paper finds that ranked choice voting nominally avoids Duverger’s Law by accumulating many identical candidates but yields fewer viable equilibrium policy positions than plurality rule. Additionally, ranked choice voting favors moderate candidates and policies, increasing the probability of their implementation compared to plurality rule. This moderate bias leads to lower polarization in equilibrium than is possible under plurality rule.

Many individuals struggle with oppressively high standards for their character, behavior and environment, know commonly as perfectionism. Perfectionism also carries significant attention in the fields of psychology, at least partially because of its association with higher rates of OCD, depression and anxiety, but also higher performance and goal-achieving (Lunn et al., 2023). The presentation will be synthesized from available literature, and focus on how perfectionism can be positive or negative, and how to effectively adopt beneficial perfectionism. Special emphasis will be placed on the role of perfectionism in academic and workplace settings.There are moderating factors that distinguish adaptive perfectionism from maladaptive perfectionism and various sources of perfectionism, including self-prescribed, socially-prescribed, and other-oriented perfectionism (Benson, 2003). There are diverse explanations of the many ways individuals strive for perfection, or how they impose expectations of it on others, and many of those will be elaborated on. Therapists have both the ability and the professional responsibility to assist in those efforts. The therapeutic modalities specifically suited for working with perfectionism and the consequences of complex relationships between it and certain mental illnesses will be presented for analysis. This discussion will benefit individuals inside and outside of mental health professions alike through exploreing the process of turning perfectionism adaptive, as well as provide direction for future research in on the topic.References:Lunn, J., Greene, D., Callaghan, T., & Egan, S.

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.

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.

The abundance of microplastics within Earth’s environment is of great concern to public health. Heavy toxic metals like lead and mercury concentrate on the surfaces of microplastics, and can readily enter the biosphere. This poses a risk to humans and other forms of life because of the large amount of microplastics that have been found in even the most remote locations on Earth. Not much has been studied about the origins and presence of microplastics in Utah snow. It would be beneficial to study microplastics in snow because, once the snow melts in the spring, it is a substantial source of water for Utah and communities in the American West. Preliminary data indicates increased concentrations of microplastics in snow samples that originated from ski resorts compared to snow samples in areas with little recreation. The current project further investigates the origins and quantity of microplastics in the snow at the Sundance ski resort. Snow samples from the Sundance ski resort and from a remote location with little human activity are compared. Additionally, the number of microplastics at Sundance between natural and artificial snow samples are compared to see if the plastic components within snowmaking machines generate a greater amount of microplastics in the snow. To investigate if snowboards and skis can release plastics, microplastics in fresh snow are quantified before and after snowboard contact. Because microplastics can also be shed from clothing, researchers also examined samples for fibers generated from winter garments. This project aims to shed light on the sources and number of microplastics in Utah snow, especially the effects of skiing and snowboarding.

There is convincing data on the potential relationship between predator-prey environments and cognitive abilities. There is often an increase in cognition found in species living among predators. Culum Brown and Victoria A. Braithwaite (2005) conducted an experiment to test this hypothesis on Brachyraphis episcopi. While they anticipated their results would support this hypothesis, the populations under non-predator conditions solved the cognitive tests more quickly. In this study, I replicate their experiment with a different species, named Brachyraphis rhabdophora, to determine if their results are repeatable. Populations of Brachyrhaphis rhabdophora are found in northwestern Costa Rica and are distinctly segregated into different river drainages. In each drainage, the populations are isolated into predator and non-predator populations. These populations experience a parallel separation of social environment to the populations used by Brown and Braithwaite. Using their same methodology, we measured cognition in Brachyrhaphis rhabdophora by presenting them with the task of locating a hidden food patch. I expected that that the predatory-prey population would complete this task more efficiently, although it’s possible that this species could produce the same contradictory results. Once the data are all collected, I will present the results and publish a paper on my findings.

Authors: Parker R. Carlquist, Lexi Brady, Seth Dotson, Jeff Glenn. Mentors: Jeff Glenn. Insitution: Brigham Young University. Background: Addressing public health problems requires cooperation from stakeholders who may have wide-ranging political, religious, moral, and societal beliefs. If stakeholders lose trust and mutual understanding between one another, the influence of public health efforts decreases. The COVID-19 pandemic illustrated these complexities as communities became divided in opinions regarding the appropriate response. Without systems and strategies to maintain and increase trust, divisive public health issues may become unsolvable. Objectives: The Campus Conversations project analyzed the effectiveness of reflective structured dialogue (RSD) in helping develop skills and abilities to address difficult conversations and topics. The project hosted conversations among Brigham Young University students of varying demographics and ideologies on divisive topics such as diversity and gender.Methods: Students were recruited to participate in an hour-long conversation with 4-6 others, including a student facilitator who guided the conversation. Conversations began with foundational agreements followed by 3 rounds of questions. Participants were each given an opportunity to speak uninterrupted in each round, followed by group discussion and questions. The structure encourages the sharing of personal experiences and beliefs in an environment that fosters understanding instead of judgement. Pre- and post-conversation surveys were administered to measure the effects of the conversations on skills. Participants were asked to rate how important they believed a skill was and also assess their ability to use it. A collection of 8 different skills and 6 different mindsets/abilities were measured. Results: Survey results found that participation in a conversation using RSD is associated with statistically significant improvements in how students rated the importance of 6 different skills. Additionally, 8 skills and mindsets/abilities saw statistically significant improvements in students’ assessed capability. The skills of “vulnerability” and “suspending judgement” saw the greatest improvements in both rated importance and assessed capabilities. The average change between pre- and post-surveys overall was a 10.5% increase. Conclusions: In order to develop effective public health policies, consensus and understanding must be achieved among stakeholders and communities. The results highlight the potential for RSD conversations to be used as an effective tool to improve students’ belief in the importance of skills required for difficult conversations and potentially improve their ability to use them. Public Health Implications: Public health is currently working to address various divisive problems that require collaboration from stakeholders that range across the political, demographic, and societal spectrums. Utilizing RSD can help promote understanding and the ability to discuss divisive issues in a calm and structured way, forming a foundation whereupon policy can be effectively created, discussed, and advocated.

As e-cigarette use has increased in popularity among the general population, especially among adolescents, the demand for research has become evident. E-cigarettes became available in the United States in 2007 and were created as a tobacco cessation tool, even though there is no current research supporting those claims. The wide array of flavors is attributed to the growing popularity of e-cigarettes with known and unknown properties. There is some overlap between the chemicals found in traditional cigarettes and e-cigarettes including nicotine. Some of the most negative effects of these ingredients include carcinogenic effects and negative oral manifestations such as hairy tongue, xerostomia, inflammation, and increased incidence of periodontal disease. For decades dental professionals have been interviewing patients regarding their smoking habits; however, with the rise of e-cigarette use, there is a greater demand for patient education. It is crucial that dental professionals take on an active role when it comes to preaching the truths about the dangers of e-cigarettes and the negative impact on oral health.

Abstract: Addressing Teenage Pregnancy and Related Public Health Issues in Rhino Camp Refugee Settlements in UgandaIntroductionWhen individuals cross international borders for fear of persecution due to reasons such as their race, belonging to a particular religion, or political group and seeking safety, they become refugees in the new host country. In most resource deprived countries, these refugees are placed in refugee camps where they receive necessities such as food, water, medical care, or shelter. However, in some cases even in these intended safe refugee camps there are many social and public health challenges mostly due to overcrowding. Teenage pregnancy, which is girls getting pregnant between the ages 10-19 is one of those issues not well investigated within refugee camps. Teenage pregnancy is associated with several adverse outcomes for young mothers including intergenerational cycles of poverty and is the leading cause of death among adolescent girls.MethodsUsing constructs from the community-based participatory research approach, the authors used mixed methods study in June 2023 to collaborate with community members to assess and initiate culturally acceptable teenage pregnancy interventions in Rhino Camp Refugee Settlement. Play and sports activities were used to enhance collaborative efforts between community members and researchers.FindingsMeasures intended to decrease the spread of Covid-19 such as tough lockdowns might have increased risk sexual behaviors and abuse and therefore increased teenage pregnancy. Community leaders are in search of appropriate interventions to reduce teenage pregnancy and provide education to teenage mothers.ConclusionThe study resulted in a collaborative interest between researchers, public health providers, and community leaders to identify culturally acceptable teenage pregnancy measures of intervention. Organized play activities, and menstrual clinics proved to be excellent ways to share teenage pregnancy and related public health challenges information including preventive measures.
