Examining The Relationship Between Active And Passive Screen Media Design, Engagement, And User Motivation And Impacts On Mental Health In Emerging Adults, Susan Richey

Human Development and Family Sciences Undergraduate Honors Theses

Rates of depression among adolescents and emerging adults have increased in recent years, with screen media use identified as a potential contributing factor. Prior research links passive screen use to poorer mental health outcomes, while active engagement shows mixed effects; however, many studies overlook differences between platform design and actual user behavior, as well as the role of notifications. This study examined how screen media habits, platform design, user motivations, and notification settings relate to mental health among emerging adults. A sample of 399 participants (ages 18–29) from a large southeastern U.S. university completed a survey assessing screen use, engagement …

Adolescent Social Media Use And Associations With Parental Screen Time Practices, Joseph A. Simon, Josiah Leong

Biological Sciences Undergraduate Honors Theses

The rise of electronic use among younger generations has raised concerns surrounding  the developmental and behavioral effects of increasing usage. While past research has found some associations between screen time and mental health, there is less knowledge about how parenting practices influence these developmental and behavioral patterns of social media use. Our study examined longitudinal trajectories of social media use from ages 9 to 13 among 9,211 subjects at baseline, year 1, year 2 and later a complete 3-year parent questionnaire on screen time reward, limiting, and monitoring to then examine whether parenting behaviors were associated with previous social media …

Sex Differences In How Celebrity Crushes Bolster Self-Perceived Mate Value, Madyson M. King

Psychological Science Undergraduate Honors Theses

Previous research indicates that parasocial relationships provide surrogate connections for individuals to where they offer various psychological benefits. Some benefits include self-esteem and improved body image, which may be connected by such relationships facilitating attainment of one's ideal self. Given this benefit of social surrogacy, it could be possible that a vicarious romantic connection with a parasocial figure may similarly bolster one's mate value if that relationship were to move an individual closer to a personal ideal. We predicted that engagement with a celebrity crush would be associated with a heightened mate value. A community sample of men and women …

The Effects Of Cannabidiol (Cbd) On The Social, Cognitive, And Physical Facets Of Anxiety Sensitivity, Ezri Rathbun

Psychological Science Undergraduate Honors Theses

The current study investigated how repeated administration of 300mg of cannabidiol (CBD), when compared to a placebo, affects the social, cognitive, and physical facets of anxiety sensitivity (AS), a characteristic that reflects fear of the consequences of anxious arousal. Prior work suggests CBD may have anxiolytic effects that may be specific to the social aspects of anxiety. Thus, it was hypothesized that, that, relative to placebo, CBD would reduce self-reported AS-social concerns, but not AS-cognitive or AS-physical concerns, compared to baseline. Participants (N= 79; 52 women; M_age = 22.06) with elevated perceived stress were randomly assigned to 14 …

Amusement In The Absence Of Empathy: Psychopathy In Relation To The Use And Appreciation Of Dark Humor, Jolie A. Brewer

Psychological Science Undergraduate Honors Theses

Although humor functions to foster integration between individuals, not all types of humor are equally appreciated by everyone. Some forms of humor are controversial, which limits their appreciation to specific contexts and potentially to specific people. One form of humor that may meet this definition is dark humor. Production of dark humor could imply that the humorist is disinterested in conventional social situations while similarly conveying an exploitative intention. Given that individuals who exhibit heightened levels of psychopathic personality traits also have a relative disinterest in adhering to social norms, it could be possible that psychopathy is associated with a …

Avoiding Pathogens Or Avoiding People? Pathogen Avoidance, Pathogen-Specific Stereotypes, And Intergroup Bias Toward South Asians, Aashvi Dahiya

Psychological Science Undergraduate Honors Theses

People are motivated to avoid pathogens because infection poses serious risks (e.g., illness, death). Pathogen avoidance often relies on indirect cues and stereotypes—like appearance or group membership—to identify potential pathogen threats. A large body of literature has linked pathogen avoidance to intergroup bias, but recent work suggests that this link may vary across social groups. In particular, pathogen avoidance may be more strongly associated with intergroup bias toward groups specifically linked to pathogen-specific stereotypes. The present study examined whether pathogen-specific stereotype endorsement moderates the relationship between pathogen avoidance and intergroup bias toward South Asians. A sample of 684 participants completed …

Navigating New Environments: Acculturative Stress And Substance Use Among International Vs Domestic Students From Latino/A Backgrounds, Madelyn R. Null

Psychological Science Undergraduate Honors Theses

College students can experience a range of cultural and social pressures that could relate to their alcohol and cannabis use. Latino/a international students may face unique challenges as they adjust to campus environments in the United States (U.S.), yet little research has compared their substance use patterns to those of Latino/a domestic students. Therefore, the present study aims to examine whether: (a) Latino/a international and domestic students differ in their alcohol use, (b)they differ in their cannabis use, and (c) acculturative stress moderates the relationship between international student status and these substance use behaviors. Latino/a undergraduates (n=440; Mage=20.55; female=71%; international=21%) …

Primate Craniofacial Trauma And Its Relationship To Socioecological Factors, Kaitlyn Harden R. Harden

Anthropology Undergraduate Honors Theses

Postmortem analysis of the skeleton can reveal patterns of trauma that have accumulated over an individual’s lifetime. Patterns of trauma within a species can also provide key insights into how that species lived and reflect aspects of their socioecology and life history. Research has been conducted often on postcranial trauma, but is rare regarding the craniofacial region and has not been examined broadly across primates. To fully understand patterns of trauma in primates, rates of trauma must be compared and placed into context of a variety of socioecological factors. To do so, I examined hypotheses including that species with higher …

Preserving The Past: Exploring The Last Frontier's Ecosystem Shifts And Biodiversity Of The Tallgrass Prairies, Gisell Maldonado, Amelia Villaseñor

Anthropology Undergraduate Honors Theses

In North America, grasslands are a cornerstone of the environment. Historically, the tallgrass prairie was expansive and reached from Manitoba in Canada to Texas. Today this unique ecosystem is highly fragmented and reduced, but it remains an important ecosystem for biodiversity and cattle management. While there are many complex ecological interactions in the prairie, recent research shows that large herbivores are vital in maintaining grasslands through grazing and other behaviors that reduce woody encroachment and support nutrient cycling. Here, we examine cow and bison dietary behaviors and connect these to the ecosystem services provided by these large herbivores. In the …

Athletes that compete in high-intensity sports or without adequate caloric intake, are at risk for low energy expenditure which may disrupt hormonal balance. As development of RED-S is a well-established risk factor for amenorrhea, early detection and correction is crucial to prevent long term health consequences.

Purpose: The purpose of this research is to explore if there is a correlation between RED-S score and amenorrhea in female athletes.

Methods: An online survey was distributed to approximately 220 female athletes at the University of Arkansas using Qualtrics. The 69-question …

Survey Of Medieval Literature On Maternal Mortality, Postpartum Care, And Birth Trauma In Relation To The Crisis In Arkansas, Paige Q. Thompson

English Undergraduate Honors Theses

When the general public thinks of childbirth in the Middle Ages, they think of death and danger. However, Arkansas has the highest maternal mortality rate in the entire United States, and many of those deaths are preventable. There have been previous analyses on different medieval texts as well as research into modern Arkansas, but none have made a direct connection between the two subjects. By analyzing medieval literature to understand cultural norms surrounding childbirth and postpartum care, patterns can be traced to modern Arkansas, where needless deaths are still prevalent. Ultimately, medieval texts demonstrate cultural attitudes surrounding blame toward women …

This study tested the level of correlation/predictability between executive functions, specifically, updating, shifting, and inhibition, and creativity. Participants (N=112) completed tasks assessing updating (letter memory), shifting (number letter) and inhibition (Stroop). They also completed the Alternative Uses Task (AUT) that measures divergent thinking. Pearson’s correlations and multiple regression analyses were conducted to examine any individual or combined relationship between executive functions and creativity. Results …

Cholesterol Effect On The P-Glycoprotein Conformational Dynamics, Zane Bunn

Biological Sciences Undergraduate Honors Theses

P-Glycoprotein (Pgp) is a human efflux pump that belongs to the ABC transporter family. This protein consists of two transmembrane domains (TMD) that convert between inward to outward facing configurations to remove a wide variety of structurally different compounds from the intracellular membrane into the extracellular space using ATP.  This non-specific efflux of compounds has brought Pgp to scientific light as having a major role in multi-drug resistance of many diseases, and researchers are focused on developing a deeper understanding of the protein. To further this understanding, this study analyzed how the structure of Pgp is affected by a 10% …

Can Methanogens Grow On Asteroids?, Isabella N. Reimer

Biological Sciences Undergraduate Honors Theses

Because of asteroids’ chemical features, they may serve as potential environments for life and are of interest in astrobiology. Dr. Kral’s laboratory studies methanogens, microorganisms in the domain Archaea, as possible life forms on extraterrestrial bodies. Since some methanogens can withstand harsh environmental conditions and produce methane as a waste product, methane production can be used as an indicator of potential microbial activity.  In this study, three methanogen species, Methanothermobacter wolfeii, Methanobacterium formicicum, and Methanosarcina barkeri were tested for growth on asteroid simulants based on the Orgueil (CIE-1) and Murchison (CME-1) meteorites. First, methanogen growth was assessed in the …

Developing Warning Signage For Harmful Algal Blooms At Lake Fayetteville, Abigail R. Evans

Biological Sciences Undergraduate Honors Theses

The presence of harmful algal blooms (HABs) poses many risk factors for human health, and once microcystin concentration has reached a certain level, that water source will be closed for the duration of the bloom. Agencies tend to use static signage with limited information to inform the public about the current status of the water, but a sign similar to the one used by the National Fire Danger Rating System can allow for constant updates detailing specific risk levels for the public. Using previously reported data on Lake Fayetteville, thresholds for risk factors that are easily measurable were determined. The …

The Genetic Basis Of High Transformation Efficiency In The Model Yeast Saccharomyces Cerevisiae, Mary Kathryn E. Cheek

Biological Sciences Undergraduate Honors Theses

Transformation, a type of horizontal gene transfer, describes the uptake, maintenance, and integration of environmental DNA by cells. Despite the known effects of transformation on evolutionary processes, little is known about the genetic basis of this phenomenon. Saccharomyces cerevisiae is a eukaryote able to transform at quantifiable rates when made chemically competent and treated with a heat shock. S. cerevisiae also has variation in transformation efficiencies between various strains, and high recombination rates allow for sufficient allele “shuffling” in intercross populations. This project utilizes a bulk segregant analysis approach to compare sequencing data between transformant pools and non-transformant pools of …

The Role Of Cognitive Inhibition In Creative Problem Solving, James Schnoes

Biological Sciences Undergraduate Honors Theses

Creativity is a defining characteristic of human cognition and plays a central role in shaping our daily lives. In the literature, creativity is commonly conceptualized through two cognitive processes: divergent thinking, which involves generating multiple novel ideas, and convergent thinking, which involves arriving at a single correct solution by integrating all information available. (Cropley, 2006; Guilford, 1959; Runco & Jaeger, 2012). The present study examined how cognitive control, measured via the Stroop task (Stroop, 1935), relates to convergent creative problem solving as assessed by the Compound Remote Associates (CRA) task. Additionally, trends in alpha and theta power spectra during the …

The Effect Of Facial Adiposity On Hypothetical Medical Treatments As A Function Of Disgust, Lindsey Duran

Biological Sciences Undergraduate Honors Theses

Perceivers are capable of estimating the health of individuals through cues to facial adiposity, with such inferences having accuracy in recognizing worse chronic health among those exhibiting greater adiposity. Nonetheless, these inferences could extend beyond health assessments into subsequent anti-fat prejudice based on perceptions of such individuals as pathogenically threatening. Although potentially functional in ancestral contexts, modern healthcare settings could render this functional stigmatization a liability that results in worse medical care toward those with higher adiposity. In this study, I tasked medical workers to evaluate male and female hypothetical patients at high and low levels of facial adiposity, particularly …

Parental Monitoring And Approval As Moderators Of Peer And Parental Influences On Adolescent Drinking, Clara Pool

Biological Sciences Undergraduate Honors Theses

Adolescence (i.e., ages 12 to 18) is a developmental period marked by exploration and risk-taking behavior, which is often associated with increased risk for alcohol use. Adolescents’ perceptions of what is typical or approved behavior within their social environments (e.g., peers, parents) may be associated with their drinking behaviors. Parental monitoring is related to reduced substance use risk, though peer and parental influences can interact. For example, adolescents who perceive their parents do not approve of adolescent alcohol use may be less susceptible to alcohol-approving peers. Therefore, this study examined how adolescents’ perceptions of peer approval, parental approval, and parental …

Enhancing Methods For Load Rating Bridge Timber Piles, Aashish Ghimire

Graduate Theses and Dissertations

Timber piles are widely used in bridge foundations across the United States due to their low cost and ease of installation. The strength of a timber pile is dependent on many factors including wood species, unbraced length, support conditions, age and cross-sectional properties. Cross-sectional properties are highly impacted by the progression of biological deterioration which often is undetected when using standard DOT inspections methods. Current inspection practices rely primarily on subjective methods that provide limited quantitative information about a pile’s existing load-carrying capacity. Consequently, timber piles are inaccurately assessed and prematurely replaced. In response, this thesis investigates the relationship between …

An Assessment Of The Basihyal And Its Functional And Ontogenetic Relationships To The Masticatory Apparatus In Primates, Parker Mitchell Taylor

Graduate Theses and Dissertations

The hyoid is central to many important functions such as feeding, vocalization, and breathing. However, primate hyoid morphology has been widely understudied compared to other aspects of craniofacial morphology. This dissertation aimed to bridge gaps in the current understanding of primate hyoid morphological variation and the hyoid’s relationship with mandibular morphology. Using microCT, diceCT, and three-dimensional geometric morphometric methods, this work details broad taxonomic variation of basihyal shape, resting hyoid position, and suprahyoid muscle architecture in primates, and assesses such variation for the effects of phylogeny, allometry, and covariation between these elements and mandibular shape. These analyses were also conducted …
