  • Examining County-level Barriers to Midwife-Attended Births Among Black Women in the United States by Asia Miles

    Examining County-level Barriers to Midwife-Attended Births Among Black Women in the United States

    Asia Miles

    11-21-2025

    Background and Objectives: In 2011, the American Public Health Association (APHA) passed legislation aimed at reducing maternal mortality and morbidity by addressing shortages in maternity care providers and facilities. The purpose of this study was to examine county-level characteristics that influence Black women’s access to midwife-attended births across the U.S. Methods and Approach: Data on midwife-attended births were obtained from CDC WONDER for U.S. counties with populations of 100,000 or greater, and county-level characteristics were gathered from the Area Health Resources File. The dependent variable was the change in nurse-midwife-attended births from 2011 to 2023. Independent variables included changes in midwifery and obstetrician workforce densities, percent of women using Medicaid, percent of the population identifying as Black, percent of women with pregnancy risk factors (diabetes and preterm births), and percent of preterm births. Descriptive statistics and linear regression analyses were conducted to assess associations between these variables. Results: Increased midwife density was positively associated with the rate of Black midwife-attended births, while greater obstetrician density and socioeconomic disadvantage were associated with lower rates. Two factors from the Social Vulnerability Index also showed relationships, though interpretation was limited due to variable complexity. Conclusions and Broader Implications: Access to midwifery care for Black women is shaped by workforce availability and structural barriers. Future research should examine how hospital policies, insurance coverage, and Medicaid expansion influence access. Expanding midwifery services in underserved areas may help reduce maternal health disparities and improve outcomes for Black mothers.

  • The Role of Money in Elections by Brandon Nabbefeld

    The Role of Money in Elections

    Brandon Nabbefeld

    5-2-2025

    What if your vote mattered less than a millionaire’s donation? In every election cycle, billions of dollars flow into campaign war chests but what does that mean? Let’s follow the money and see who is truly influencing our elections. Money plays a powerful role in shaping electoral outcomes and public policy in democratic systems. In the United States, campaign funding has become increasingly dominated by large donations. This is because in 2010, Citizens United v. FEC decision opened the doors for unlimited independent political spending, sparking widespread concerns about fairness, transparency, and the influence of wealthy donors in politics.

  • Gendered Patterns of Trauma & PTSD Symptoms Among Latine Americans: A Mixed-Methods Analysis by Abigail Panariso, Gerardo Garcia, Melanie Garcia, Yajairy Carbrales, and Mariam Sultan

    Gendered Patterns of Trauma & PTSD Symptoms Among Latine Americans: A Mixed-Methods Analysis

    Abigail Panariso, Gerardo Garcia, Melanie Garcia, Yajairy Carbrales, and Mariam Sultan

    11-21-2025

    Latine communities in the U.S. experience disproportionate exposure to traumatic events, contributing to behavioral health disparities such as elevated rates of posttraumatic stress disorder (PTSD) and underutilization of mental health care. Gender, as a key social determinant of health, influences both types of trauma encountered and the severity of symptoms. Little research has tackled how gender intersects with structural inequities within Latine populations, such as discrimination, immigration stress, and socioeconomic marginalization. This mixed-methods study assessed gender differences in trauma experiences and PTSD symptoms among 328 Latine American adults (148 men, 180 women) recruited through an online survey. We predicted gender differences in trauma type and PTSD symptoms among participants, and explored whether gender and trauma type would interact and predict greater PTSD symptoms for Latine American men and women. PTSD symptoms were measured using the Short Post-Traumatic Stress Disorder Rating Interview (SPRINT). Qualitative data from open-ended survey responses helped generate four trauma categories: (1) structural/systemic trauma and severe accidents, (2) interpersonal violence and abuse, (3) sexual assault and abuse, and (4) health- and loss-related trauma. Findings highlight the importance of culturally and gender-responsive trauma assessments in behavioral health care. The differences in gender patterns, including heightened sexual violence exposure among Latinas and health-related trauma among Latinos, underscore the importance of further tailoring screening and interventions to specific risk profiles. Action-oriented interventions and clinical efforts should properly address the unique cultural stigma of disclosure and develop validating solutions to guide in lifting the burdens of trauma in Latine American communities.

    Severe heat waves may cause long-term changes in marine ecosystems and are expected to increase in magnitude and frequency. Here we use surveys from six localities across a six-year interval (2013-2019) to investigate the effects of heat waves on the functional diversity of rocky intertidal ecosystems (Vancouver Island, Canada).

    Functional diversity, the number and types of functions performed by organisms, influences ecosystem stability and health. To assess changes in functional diversity we used analyses of biological traits. Biological traits are measurable properties of organisms that describe their morphology, physiology, and behavior. We quantitatively assessed changes in functional diversity in response to marine heatwaves in 2014-2016, and 2019.

    Understanding changes in functional diversity in response to climate change is essential to effectively manage ecosystems as heatwaves are expected to increase in frequency and magnitude.

  • Effect of Neuroinflammation on Exploratory Behavior in Mice by Gage Pompa, Ariana Mitic, Yader Gomez, Lilian Hagos, and Orlando Montiel

    Effect of Neuroinflammation on Exploratory Behavior in Mice

    Introduction: Mice have been observed in both laboratory and field settings to exhibit a tendency to remain near corners and walls. This trait is known as positive thigmotaxis. Thigmotaxis has been recognized as a fundamental aspect of rodent behavior and used extensively as an anxiety index in mice. Although this characteristic has been recognized as a fundamental aspect of rodent behavior, thigmotaxis has been extensively studied in rectangular and circular environments. However, there is a notable lack of understanding of how alternative geometric configurations can influence this behavior.

    Methods and Approach: Using a grid overlaid on the environment the mice were in, we were able to extract the X and Y points to describe the horizontal and vertical positioning of the mice within the environment. These points were obtained from previous experiments involving male and female mice before and after inducing neural inflammation. We were able to track the mice both in time spent and distance traveled within each subdivided region of the shaped environments. This was done by using a neural implant to track where the mouse was within the environment. After collection, data was inputted into MATLAB for analysis. Using custom written code to analyze the data we were able to evaluate the potential sex-specific differences before and after neural inflammation.

    Results: Our preliminary analysis has provided a strong framework for evaluating and analyzing the difference in both time spent in different regions in the environments and total distance traveled. However further examination will be needed for us to draw conclusions on how thigmotactic behavior is affected by these different environments.

    Conclusions: Our findings indicate that insights from this research could be used to design experimental mazes to elicit specific spatial behaviors in mice. Environments can be created to either draw the mice to the center of the environment or to draw them closer to the wall for the experimental design. This will save lots of time that is currently spent on designing environments for mice that may or may not have the desired effect. We also concluded that the information learned from this research could be used to better design rodent enclosures for pet owners to create an environment that is less stressful and more calming for the mice. This could possibly change what type of enclosures are currently being sold to owners of mice.

    The hippocampus has known roles in memory formation, learning, and spatial mapping. There are defined physiological differences between CA1 neurons based on their dorsal to ventral position within the 3D hippocampus (Malik et al., 2015). Given the varying functions of the dorsal and ventral hippocampus in cognitive processing and the role of the dentate gyrus as the entry point for information into the hippocampus, it will be interesting to determine if there are differences in the properties of granule cells across the dorsal and ventral axis. We explore the potential topographic specialization of dentate granule cells. This study examines the relationship between the neurophysiology of granule cells in the mouse dentate gyrus and their dorsal/ventral position in the hippocampus. Forty-four mouse hippocampi were sampled and assessed for dorsal/ventral position, spike train frequency, resting membrane potential, and action potential threshold. Using an established mapping algorithm for the rodent hippocampus, we mapped hippocampal slices for their dorsal/ventral position. Our sampling covers a range from very ventral to intermediate dorsal hippocampus. Physiological properties of CA1 cells display a linear relationship with their dorsal/ventral position. Therefore, we used linear regression to map the physiological parameters of dentate granule cells with their calculated dorsal and ventral position. We found that the physiological properties of dentate granule cells, unlike CA1 neurons, did not vary with their dorsal/ventral position within the hippocampus. Future experiments will record properties of dentate granule cells from the most dorsal location to complete the dorsal/ventral extent.

    Stationary Phase Mutagenesis is a process where a bacterium can accumulate mutations in the absence of cell division. This may occur via competent DNA uptake and oxidant DNA damage and repair. ComEA is a transmembrane protein in B. subtilis that is required for the transport of exogenous DNA into the cell. (Figure 1)

  • Prediction Error's Influence of Declarative Memory: A Replication by Camila Schettini and Kevin Mohawk

    Prediction Error's Influence of Declarative Memory: A Replication

    Camila Schettini and Kevin Mohawk

    11-21-2025

    We often have predictions about what to expect in our everyday encounters. However, not all these predictions will be accurate. Prediction error (PE) refers to the discrepancy between expectations and actual observed outcomes, and it is believed to play a role in learning, such as in classical conditioning. Yet, its relationship to one-shot declarative memory remains poorly understood. In the present study, we aimed to replicate Greve et al. (2017, Experiment 1) by testing whether PE enhances memory. Participants first learned scene-word associations in which a specific scene image was paired with one of two category labels, “positive” or “negative”. For example, participants learned that images of gardens were associated with the label “negative”, and images of kitchens were associated with the label “positive”. This learned association was later violated (to produce PE) in a later phase by presenting a specific emotional word from the opposite category label (e.g., gardens paired with the word “happy”). PE occurred on 30% of the trials, while the remaining 70% of the trials were consistent with the learned associations. Finally, the last phase included a memory test over the image and emotional word pairings. A successful replication of Greve’s findings would be better memory for trials where the association was violated compared to trials where the word was consistent with the association. However, preliminary data indicate that memory remains equal across trials and is not enhanced by PE. This also suggests that mismatches between expectations and outcomes may not always enhance associative memory.

  • Relationship Between Caffeine Use and Eating Disorders by Hannah Segura and Maegan Nation

    Relationship Between Caffeine Use and Eating Disorders

    11-21-2025

    Eating disorders are a spectrum of cognitive, behavioral, and physical symptoms related to eating and compensatory weight management behaviors. Body image concerns can be a significant risk factor for various disorders, such as anxiety, depression and eating disorders. Additionally, eating disorders are commonly comorbid with other psychiatric disorders. Supplement usage such as performance enhancing supplements is becoming increasingly common, especially among younger populations. Using different supplements has been shown to put adolescents at an increased risk for body dysmorphia, disordered eating behaviors, as well as other potentially harmful health effects, like electrolyte complications, heart issues, or even death. Across the past 10 years, supplement use in college students has increased 19.5%. Overall, there is a lack of consensus of what typical use among college students looks like and what exactly they are used for. Additionally, there is less research done on supplement usage in the college student population, especially in men. This study will analyze supplement usage as a risk factor for eating disorder pathology in a college population. A linear regression will be used to test the relationship between supplement usage and eating disorders. There is an expectation of men using supplements more than women and that there is a positive relationship between supplement use and eating disorders.

    In recent years, mental health concerns among college students have increased significantly. This study aims to analyze data on student willingness and frequency to seek counseling services, such as UNLV CAPS (Student Counseling and Psychological Services), and the appeal of utilizing alternative interventions such as exercise and meditation. This study collected data from UNLV students, faculty, and staff through distribution of a scannable QR code. It included whether they were in therapy, the PHQ-9 and GAD-7, their respective functional impairment questions, and willingness to consider therapy alternatives. Based on respondents’ answers to the PHQ-9, the highest proportion peaked at 36% for minimal symptoms. The GAD-7 responses showed the highest proportion of answers at 44.9% for mild symptoms. Most notably, 70% of students reported not currently being in treatment for anxiety or depression. With that, 74.2% of respondents stated that they would seek help through university mental health services, with 94.4% saying they would seek alternative treatments to therapy or medication. There were significant positive relationships between anxiety severity and depression severity. Participants experiencing minimal anxiety were more likely to not seek alternative treatments to therapy or medication when feeling depressive or experiencing anxious symptoms. Participants indicating that they experience severe anxiety were more likely to express that they would seek alternative treatments to therapy or medication. It is shown that members of UNLV’s community would be largely open to alternative or holistic approaches to therapy and medication disbursement.

    5-2-2025

    Objective: Test whether the well-established effects of divided attention 1, 2. (DA) found with non-musical (i.e., verbal and pictorial) materials generalized to musical melodies.

    Background: Few studies have used melodies to test recognition models (e.g., DPSD). Parks et al.2 showed stimulus complexity alters source memory reliance on recollection (R) and familiarity (F).

    Method: Used a 2 (attention) x 2 (melody type) mixed design with an old-new recognition test to compare DA effects across well-known and novel melodies.

    Experiment 1: Applied an n-back task to split participants’ attention; no significant DA effect was observed.

    Experiment 2: Shortened melody length and added a simultaneous DA task to address ceiling performance issues from Experiment 1.

  • The Coso Paradox: An Additional Perspective of Indigenous Identity by LeeAnna Sueno

    The Coso Paradox: An Additional Perspective of Indigenous Identity

    5-2-2025

    The Coso Mountain Range in Inyo County, California is an archaeological site rich with evidence of human interactions throughout prehistory. One of the most striking features is Coso’s abundance of rock art, estimated at over 100,000 etchings, with over half depicting Ovis canadensis (Bighorn Sheep). Coso’s rock art has been long-debated as a site of “shamanistic” prevalence, including vision quests, rain god worship , and interpretations of fertility. While spirituality is an integral part of many Indigenous cultures, it is highly unlikely that such a mass creation spanning hundreds of years and multiple cultural groups would be solely spiritual.

  • Real-Time AI-Enabled Therapeutic Device for Improving Peripheral Perfusion and Glucose Regulation in Type 2 Diabetes by Torryana Tanis

    Real-Time AI-Enabled Therapeutic Device for Improving Peripheral Perfusion and Glucose Regulation in Type 2 Diabetes

    Torryana Tanis

    11-21-2025

    Type 2 Diabetes Mellitus is frequently accompanied by peripheral microvascular disease, leading to impaired lower limb perfusion, impaired healing, and vulnerability to ulcers and amputation. The existing medical devices are predominantly aimed at systemic glucose control and do not have local therapeutic intervention to improve circulation or allow muscular glucose delivery. To meet this crucial demand, we have developed a portable, two-in-one biofeedback device that combines non-invasive blood glucose monitoring and Electronic Muscle Stimulation (EMS) therapy for the calf muscle. The glucose monitoring subsystem implements near-infrared (NIR) spectroscopy to measure skin light absorptance on the index finger. Real-time blood glucose concentration is achieved by applying a linear regression machine learning model. In parallel, the EMS subsystem delivers programmable electric pulses with adjustable frequency and waveforms to induce calf muscle contraction, promoting better blood flow and permitting physiological glucose utilization. The device is powered by an Arduino Uno microcontroller with manual and automatic modes of operation for diverse therapeutic needs. Prototype validation was verified using a logic gate analyzer to ensure pulse width integrity; concurrently, glucose monitoring achieved a marginal error rate of 30%. To enhance therapeutic precision, an artificial intelligence model analyzes user-specific monitoring data in real time and adjusts stimulation parameters autonomously to deliver personalized treatment. This customizable, dual-function platform device offers a promising pathway for non-pharmacological management and intervention against diabetic microvascular complications.

    11-21-2025

    With warmer days and more frequent natural disasters, it is clear to see climate change and global warming on the rise. It is more important now than ever to spread awareness about climate change’s consequences and how we can address them. Both nature and women are oppressed by patriarchal, capitalist systems, which is why we are interested in the intersection of gender and nature in environmental media. Our hopes are to tap into an under-studied field of environmental communication by analyzing eco-horror films, which are horror films with environmental messages. Using ecofeminist rhetorical theories, we analyze how three eco-horror films personify Mother Nature through the Gaia theory and use parallelism to chart similarities between women and nature. Thus, we wish to analyze the trends in portrayals of women and nature and underlying persuasion in the films’ message about combatting the deterioration of Earth. We have selected three movies to be analyzed: Mother! (2017), Gaia (2021), and Apostle (2018). We can use this research to expose how women and nature are represented in media for the public to shape their perspectives on climate change and climate action. Our end goals are to present at the Western States Communication Association annual convention and submit the findings to Environmental Communication.

    5-2-2025

    Located in the Black Hills of South Dakota (Figure 1), Fossil Cycad National Monument boasted well-preserved specimens of cycadeoid fossils from the Cretaceous and concentrations of these fossil plants were greatest at the site’s location (Santucci and Hughes, 1998). I studied historical records to estimate the number of fossils removed by paleontologists at the site between 1890-1957.

  • Creating a Data Processing Pipeline With MNE-python by Lesly Vazquez and Ananda Liz Peixoto Couto

    Creating a Data Processing Pipeline With MNE-python

    11-21-2025

    The UNLV Psychophysiology of Emotion and Personality Lab (PEPLab) utilizes a MATLAB based pipeline to process electroencephalogram (EEG) recordings. MATLAB is a proprietary software package, which limits the ability to analyze psychophysiological data and increases the financial burden of research. To increase the accessibility of data reduction skills, we have created and tested a new pipeline utilizing MNE-Python, an open source software package (Gramfort et al., 2013). In this pilot study, we utilized existing EEG recordings and examined the relationship between the Triarchic Model of Psychopathy and Error-Related Negativity (ERN) responses across incorrect and correct trials during a Letter Shock task and compared these findings to a previous study (Peixoto Couto, 2025). The pipeline was able to successfully replicate findings of an increased ERN response when participants were high in Boldness, as well as a decreased ERN response when participants were high in both Boldness and Disinhibition. While successful in the purposes of analyzing ERN responses, further work will be required to resolve EOG overcorrection present in frontal sensors. Future studies will also require pipeline adjustments to analyze different ERP responses.

    5-2-2025

    Musical preference is shaped by listening experience

    Listeners tend to like music they’ve heard before familiarity correlates with liking (1).

    As listeners acquire knowledge of how music is structured, they make better predictions about events as they unfold.

    Familiarity and prediction are key drivers of musical pleasure (2,3).

    Present study aims to characterize the relationship between listening experience/exposure and preferences during childhood

  • From Dante’s Inferno to California: Visualizing the Marginalized in Sandow Birk’s Social Critique by Lorenzo Williams

    From Dante’s Inferno to California: Visualizing the Marginalized in Sandow Birk’s Social Critique

    Lorenzo Williams

    11-21-2025

    This research explores the intersection of medieval literature and contemporary visual art, focusing specifically on Sandow Birk’s reinterpretation of Dante Alighieri’s Divine Comedy. By examining Birk’s illustrated adaptations of Inferno and Purgatorio, this paper analyzes how he translates and visually reimagines Dante’s moral and spiritual journey as a modern critique of California’s social crises, particularly those affecting unhoused populations. It investigates Birk’s recontextualization of Dante’s allegory in relation to the urban decay of Los Angeles and San Francisco. Ultimately, this study aims to reveal how Birk’s visual narrative bridges historical understandings of religious and social issues with contemporary experiences of human suffering in the sociocultural landscape of the twenty-first century

  • The Relationship Between Gender and Experienes of Weight Stigma From Healthcare Providers by Isabella J. Aceituno and Shannon Sagert

    The Relationship Between Gender and Experienes of Weight Stigma From Healthcare Providers

    Isabella J. Aceituno and Shannon Sagert

    11-22-2024

    Healthcare providers are a common source of weight stigma, which is associated with lower physician trust, poorer patient outcomes, and the avoidance of healthcare services. Currently, there is a lack of consensus in research on whether women and men are equally likely to experience weight stigma from healthcare providers. The present study examined whether gender differences exist in weight stigma received from healthcare providers in childhood or adulthood, comfort seeking medical care, and healthcare avoidance. Adult participants (N = 196) reported the frequency at which they experienced stigmatizing experiences in healthcare environments in the past 12 months and during childhood using the Stigma Situations in Health Care (SSHC) Scale. The Measure of Healthcare Avoidance (MHA) was used to investigate reasons participants might avoid seeing a doctor, and two additional survey questions gauged participants’ comfort seeking medical care in the past 12 months. Logistic regressions showed no gender differences in past experiences of weight stigma (X2 = .072, 1 df, p =.789) or current experiences of weight stigma (X2 = 2.112, 1 df, p = .146). Furthermore, point-biserial correlations showed no association between gender and comfort seeking care (rpb = .051, p =.480) or healthcare avoidance (rpb =.005, p =.941). These findings suggest that men are as likely as women to experience weight stigma from healthcare providers in both childhood and adulthood, and exhibit comparable levels of healthcare avoidance and comfort seeking medical care. Future research should further examine the frequency and nuances of weight stigma in men, women, and gender-diverse individuals.

  • "Screen Time" and the Perception of It Among Different Social Classes by Jasmine Ayon

    "Screen Time" and the Perception of It Among Different Social Classes

    Jasmine Ayon

    11-22-2024

    “Screen Time” and the subsequent demonization of it is a phenomenon that is not as analyzed through a social and comparative lens as much as psychological and health ones. To address this gap in research, we performed a content analysis on articles concerning families and “screen time” use that were published on two well-known parenting websites SheKnows and Parents.com from 2019 - 2022 (n = 220). In this paper, we address how these articles talk about screen time use among different social classes. In our analysis, we found what appears to be a double standard in the way screen time use is perceived among different classes. Families of higher income are less demonized for screen time use, and have easier access to exercise familial activities that do not rely on a device. It is important to recognize these biases in the popular discourse in order to understand the nuances present within it and to navigate future discussion on it.

  • Repurposing Non-toxic and Cost-effective Organic Ligancds to Enhance the Removal of Uranium and Thorium From Wastewater by Will Campbell

    Repurposing Non-toxic and Cost-effective Organic Ligancds to Enhance the Removal of Uranium and Thorium From Wastewater

    11-22-2024

    Cheap, effective and industrially practical remediation methods for uranium and thorium are of utmost importance. Electrocoagulation is a cheap but only mildly effective method for the remediation of these elements. It was recently shown that chelating ligands enhance this process. Unfortunately, few ligands have been tested for this enhancement. Of these, the most effective, Alizarin Red S, had a 99.2% uranium removal efficiency but was expensive ($3.6 / g), toxic to humans and environmentally harmful. Therefore, ligands that avoid these downsides are needed before any industrial application can occur. Potential ligands were found via exhaustive searches of MilliporeSigma’s database. Over 3000 ligands were examined ranging from the histological stains (486 potentials) to organic building blocks (>3000 potentials). From these ligands, it was narrowed down on four criteria. The price must be below $2 / 1 gram, non-toxic to humans, environmentally friendly and selectively chelate to uranium or thorium. Four potential ligands were found from the over 3000 which fit all four qualities well. The differences however included the solubility in water, charge and price. Pamoic acid ($1.33 / g) and quercetin ($1.88 / g) are neutral molecules with low water solubility. Acid blue 40 ($1.6 / g) contains a single negative charge and Acid blue 80 ($1.5 / g) and contains two negative charges. Both have excellent water solubility due to their ionic charges. Herein, we effectively found four potential ligands for use in the removal of uranium or thorium from water via ligand enhanced electrocoagulation.

  • Parental Failure and the Double Standards of Screen Time Discourse on Popular Parenting Blogs by Christian Casarez and Annaliese Grant

    Parental Failure and the Double Standards of Screen Time Discourse on Popular Parenting Blogs

    Christian Casarez and Annaliese Grant

    11-22-2024

    Understanding screen time discourse is vital in grasping people’s relationship with media comprehensively. This research seeks to add to this body of knowledge by highlighting the double standards present within parenting blogs’ narratives on screen time. Utilizing a qualitative analysis conducted on a dataset of over 200 coded articles (n=220) from parenting blog giants such as Parents.com and SheKnows.com, I argue that popular parenting blogs simultaneously platform content that pushes parents to constantly manage and mitigate their children’s screen time use, while at the same time implicitly encouraging parents to utilize apps, audio, content, and devices to do so. In supporting this claim, I explore the state of screen discourse on parenting blogs, various policing tactics encouraged by parenting blog content, as well as what this paper calls “narratives of parental failure,” which refers to the content & narratives depicting where parents deviated from the perceived idealized norms around screen time management and usage that were established by said platformed parenting content. I then conclude this piece by discussing the implications of these findings to our broader understanding of media, parenting, and socialization, as well as avenues future research in this area should explore.
