The Role Of Executive Functions In Creativity, Gavin R. Kyer

Biological Sciences Undergraduate Honors Theses

The present study investigates the relationship between executive functions and creativity, measured through divergent thinking. Literature review determines that there should be a positive correlation between executive functioning and creative idea generation, however, findings are mixed. 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% …

From Admission To Achievement: Evaluating The Predictive Validity Of Entrance Exams And Grade Point Average In Nursing Education, Kristen Fenlason

Education Doctorate Dissertations

At a critical time of nursing shortages, nursing programs must examine admission gatekeeping practices. The two common admission metrics, grade point average (GPA) and entrance exam scores, are inconsistently supported in the literature, particularly within the understudied population of practical nursing students. This quantitative, retrospective, correlational study examined the relationship between admission criteria and three measures of practical nursing student success: on-time first-semester completion, on-time program completion, and first-time NCLEX-PN pass rate. Data were collected from historical records of five cohorts of practical nursing students (n = 94) at a medium-sized community college from Fall 2020 to Fall 2024. …

Integrated Management Of Procambarus Clarkii Through Habitat Manipulation And Chemosensory Predator Avoidance, Allarae J. Prigan

Biology Theses

Aquatic invasive species pose a significant threat to native biodiversity, water quality, and local economies. The Laurentian Great Lakes are especially at risk with over 180 established non-native species. In particular, the red swamp crayfish (Procambarus clarkii) is a recent invader to the Lake Erie eastern watershed and requires sustained management to prevent its spread further into the region. This thesis explores a multi-faceted approach to managing this species via a habitat manipulation study and a laboratory behavior experiment.

I assessed the outcomes of winter stream dewatering on population catch per unit effort (CPUE), mean animal size, and …

Hormonal, Cytokinetic, And Skeletal Response To A Single Weighted Vest Exercise Treatment: A Pilot Study To Determine Weighted Vest “Rucking” Treatment For Osteoporosis In Post-Menopausal Women, Eleanor Pell

Master's Theses

Osteoporosis is characterized by a deteriorating of bone tissue leading to brittleness and increased fracture risk that affects both men and women as they age. Postmenopausal women are of particular interest due to high risk of declining bone density, a characteristic of this population. Treatments for osteoporosis range from menopause hormone therapy, bisphosphonates, biologics, nutritional changes, and exercise. Load bearing exercise interventions have shown effectiveness for stimulating bone growth, but many factors such as lack of access, motivation, self-confidence or knowledge, prevent long term compliance. “Weighted vest rucking” refers to a variation of rucking, which is a form of exercise …

Companion Parrot Vocal Learning And Reproduction Of Human Speech Sounds, Karla Vilches Castaño

Master's Theses

Vocal learning is rare among animals but is well developed in parrots, which can imitate novel sounds and, in captive settings, reproduce human speech. This study helps address a larger evolutionary question about vocal learning. Specifically, whether vocal learning ability is best understood as a single generalized trait or as a multi-dimensional system in which different acoustic features can be learned and reproduced with varying degrees of fidelity. This thesis quantifies how closely companion parrots match their human tutors across three acoustic dimensions (spectrographic structure, intensity contour, and pitch contour) and tests whether mimicry accuracy varies among individuals, differs between …

Investigating The Taxonomic Uncertainties Of Potentilla Rupincola, Natalie Elizabeth Hieber

Master's Theses

Landscape stewardship is an integral role for land managers that becomes more important when rare or endangered species occur within managed areas. Conservation across the landscape is a primary concern for land managers, but resources allocated for conservation can be limited due to many competing goals. Taxonomic uncertainty surrounding rare and endangered taxa, particularly plant taxa, that have historically been classified solely using morphological features further complicates conservation planning. One such taxon is Potentilla rupincola, a rare plant endemic to the eastern Rocky Mountains in Colorado. For over a century, botanists have debated whether P. rupincola is a distinct species …

Perfectionism And Cognitive Flexibility: Comparing The Impacts Of Perfectionism Vs Excellencism On Cognitive Flexibility, Lillian R. Blackburn

Honors College Theses

Perfectionism is often defined as “high standards of performance which are accompanied by tendencies for overly critical evaluations of one’s own behavior” (Frost et al., 1990, p. 450). Although striving for high standards is characteristic of perfectionism, it is also a central concept of the construct of excellencism, that is striving for standards that are both high and attainable. Research has made a distinction between the pursuit of perfection and pursuit of excellence, suggesting perfectionists strive for high unattainable standards, whereas excellencists strive for high yet reasonable standards with more areas of flexibility (Gaudreau et al., 2022).  These differences have …

The Effects Of Impervious Land Cover And Red Tide (Karenia Brevis) On The Florida Manatee (Trichechus Manatus Latirostris) In The Gulf Coast Of Florida, Anna Compton

Honors College Theses

Red tide, caused by the dinoflagellate Karenia brevis, is an algal bloom event that occurs annually in the West Florida Continental Shelf. The algae releases brevetoxin, a toxin that can be fatal to wildlife in high concentrations. These algal bloom events are thought to be exacerbated by warming ocean temperatures and increased nutrient runoff from urbanization. Red tide is responsible for the mass mortality of various marine organisms like the Florida manatee (Trichechus manatus latirostris). This study analyzes the changes in nutrient runoff and sea surface temperatures, and how these factors affected red tide cell concentrations and Florida manatee mortalities …

Minimizing Musculoskeletal Injury Risk In Health Care Professionals With Education On Physical Activity Recommendations, Emma H. Foran

Honors College Theses

Working in healthcare settings that require patient handling is physically demanding - over 80% of providers involved in patient handling report work-related musculoskeletal disorders (WMSDs). Injuries or exacerbation of a previous injury may occur if the individual cannot tolerate heavy workloads. Injuries that cause lost work time or work restrictions impact the healthcare team, may alter quality of life, and impact employee income. A practical way to minimize these effects is to prevent WMSDs. Training providers to use proper body mechanics, practice patient handling, and engage in regular exercise designed to increase muscular strength and endurance through resistance training improves …

The Brown Foundation: Institute of Molecular Medicine

Obesity and diabetes are chronic metabolic diseases affecting millions worldwide. Current treatments, including lifestyle changes, medications, and surgery, face challenges like poor adherence and side effects. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are recommended innovative medications for these conditions, with studies showing significant clinical benefits. GLP-1RAs are traditionally delivered orally or via subcutaneous injections, but these methods have limitations, including low bioavailability, poor solubility, the need for high doses, gastrointestinal side effects, and frequent dosing requirements. Novel delivery technologies offer promising strategies to overcome these challenges and enhance therapeutic effectiveness. Recent advances in drug delivery technologies, including nanocarrier- and microcarrier-based systems, …

Sorghum Grain Secondary Metabolites And Underlying Genetics To Reduce Foodborne Pathogens In Poultry, Maria A. Conti

Doctoral Dissertations

Substance use during adolescence remains a significant public health concern, particularly within Latino communities where cultural values, family dynamics, and communication patterns play a central role in youth development. This qualitative study explored how Latino parents communicate with their adolescent children about substance use, the strategies they use for prevention, and the cultural and contextual factors that shape these conversations. Using a focus group design, data was collected from four focus groups consisting of two groups of Latino mothers (n = 10) and two groups of Latino fathers (n = 9). A thematic analysis revealed six primary themes: (1) parent–child …

Things Montaigne Got Right About Medicine, Stewart Justman

Global Humanities and Religions Faculty Publications

In an article in Perspectives in Biology and Medicine a few years ago, I documented a number of Montaigne’s insights into medicine that have held up over time.  Not everyone was convinced.  Therefore I here augmented my case, adducing several other Montaignean insights and adding some particulars to one or two that were mentioned in the original article.

Tiny Tusk Internship: Gut Instincts: A Review Of Literature On The Impact Of Breastfeeding On The Infant Gut Microbiome, Rayla Payne

The Eleanor Mann School of Nursing Undergraduate Honors Theses

The purpose of this systematic review was to investigate both the short- and long-term benefits that breastfeeding has on the infant gut microbiome. The PICOT question was: In full-term infants, how does exclusive breastfeeding compared to mixed or formula feeding influence the diversity and composition of the gut microbiome throughout the first 12 months of life? For this research, EBSCOhost, CINAHL, and the National Library of Medicine databases were searched to find relevant studies and systematic reviews. Terms such as “breastfeeding and infant gut microbiome” were used to conduct the search. Other terms used included “breastfeeding OR formula feeding”, “human …

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 …
