New Algorithms For The Multiplication Table Problem, Evan Blom
New Algorithms For The Multiplication Table Problem, Evan Blom
Undergraduate Honors Thesis Collection
In 1955, Paul Erdős initiated the study of a function that counts the number of distinct integers in an (n × n) multiplication table. That is, he studied M(n) = |{i · j, 1 ≤ i, j ≤ n}|. Much research has been done in regards to both asymptotic and exact approximations of M(n) for increasingly large values of n. Recently, Brent et. al. investigated the algorithmic cost in computing this function. Instead of computing M(n) directly, their approach was to compute it incrementally. That is, given M(n−1), they could quickly compute M(n) using another function δ(n) to count the …

The advent of sports analytics has ignited a fervor across all sporting disciplines, particularly soccer, where clubs are sprinting to harness vast data reserves to elevate team performance, spearhead effective marketing endeavors, and bolster financial gains crucial for club expansion. Much like Billy Beane's transformative "Moneyball" approach, soccer clubs are in pursuit of innovative strategies to transcend financial limitations and achieve triumph. In soccer, where goals are scarce commodities, heightened offensive efficacy becomes imperative. Presently, one metric stands out as pivotal in gauging a team's goal-scoring success: expected goals (xG). This metric quantifies the likelihood of a given shot or …
Tpm^Ph Derivative Of Tungsten; Hydrogen-Bonding In 7-Coordinate Cation Complex, Olivia Ryon Simcox
Tpm^Ph Derivative Of Tungsten; Hydrogen-Bonding In 7-Coordinate Cation Complex, Olivia Ryon Simcox
Undergraduate Honors Thesis Collection
Tpm^Ph, or tris(3-phenylpyrazolyl)methane reacts with tungsten hexacarbonyl to form the ligand-metal complex tris(3-phenylpyrazolyl)methane tungsten tricarbonyl, or Tpm^PhW(CO)3. The further complexes of Tpm^PhW(CO)3 and Tpm^PhMo(CO)3 are not known. This project aims to explore how the addition of a phenyl substituent to the pyrazole ring on Tpm impacts the synthesis of [Tpm^PhW(CO)3I]+X– and [Tpm^PhW(CO)3H]+X–. The inclusion of this phenyl substituent may impact the possible hydrogen bonding of then hydrogen contained in the carbon-hydrogen bond. This work aims to explore the extent of hydrogen-bonding of the carbon-hydrogen bond of the Tpm^Ph ligand in cationic metal complexes.

Stream Gauging: Investigating The Flow Rate And Residence Time In Laguna Bacalar, Mexico, Elizabeth J. Kowalczyk
Stream Gauging: Investigating The Flow Rate And Residence Time In Laguna Bacalar, Mexico, Elizabeth J. Kowalczyk
Butler Journal of Undergraduate Research
Stream gauging is a standard tool used to measure the flow rate of various bodies of water. Knowing the flow rate of a body of water allows for the residence time of a body of water to be calculated. Currently, there is very little information regarding the flow rate and residence times of Laguna Bacalar. This system has been observed hydrologically consistently only in the past 6 years. In this study, 13 stream-gauging locations of interest were identified and gauged for their respective flow rates using the midsection method. Once the flow rates were acquired, maps depicting the Laguna Bacalar …

Air Temperature And Diet Are Not Associated With Oxygen Consumption Rate In Banded Crickets, Gryllodes Sigillatus, Nicole Bailey, Connor Oakes, Rachel Sleeth, Mallorie Smith
Air Temperature And Diet Are Not Associated With Oxygen Consumption Rate In Banded Crickets, Gryllodes Sigillatus, Nicole Bailey, Connor Oakes, Rachel Sleeth, Mallorie Smith
Butler Journal of Undergraduate Research
All living organisms acclimate to their environments, with ectothermic species particularly susceptible to environmental change, specifically temperature. Ectothermic insects like crickets directly alter their physiological processes depending on the environment in which they live. Temperature is vital in regulating processes such as metabolism, respiration, and reproduction, among other things. What remains unclear is how a change in the environment, specifically extreme temperature change and dietary alterations, affects physiological processes. In this study, we performed experiments on ectothermic banded crickets to examine the effects of temperature change and the interaction of temperature and diet on oxygen consumption. For both experiments, we …
Effects Of Anthropogenic Noise On Body Mass In Gryllodes Sigillatus, Jessica L. Venturi, Joyce Zheng
Effects Of Anthropogenic Noise On Body Mass In Gryllodes Sigillatus, Jessica L. Venturi, Joyce Zheng
Butler Journal of Undergraduate Research
Insects use vibrational structures to produce and sense airborne sounds in intraspecific communication. These signals are important in courtship as well as defensive behavior against predators. For example, insects can detect the presence of nearby predators using vibrations. With an increase in anthropogenic activity, processing these signals and the constant threat they represent may increase stress on insects, subsequently affecting their behavior and physiology. Our experiment was designed to determine whether anthropogenic noise, possibly perceived as a stressor, will decrease the body mass of banded crickets, Gryllodes sigillatus. We predicted that the anthropogenic noise would stress the crickets, leading to …
Truth, Not Accuracy: Native American Fiction Vs. White Settler Colonialism, Charles Democker
Truth, Not Accuracy: Native American Fiction Vs. White Settler Colonialism, Charles Democker
Butler Journal of Undergraduate Research
For centuries, depictions of Native American culture have largely been constructed by White authors and have thus reflected white settler colonialist ideology. This paper suggests that one way to counter this point of view when studying Native American history is to turn to fiction, specifically fiction written by Indigenous authors. Taking as an example Ojibwe author Louise Erdrich’s Plague of Doves, a novel based on the real-life massacre of a frontier family in the late nineteenth century, this paper argues that the creative fiction of Indigenous authors can counter the biased, incomplete, and often incorrect official histories of White–Native interactions. …

Almost 30 Years Later: Anti-Femicide Activism In Mexico From 1993 To 2022, Kathryn Webb
Almost 30 Years Later: Anti-Femicide Activism In Mexico From 1993 To 2022, Kathryn Webb
Butler Journal of Undergraduate Research
What factors have influenced the strategies of the anti-femicide social movement, and what has this movement accomplished after continuously advocating for almost 30 years? Analyzing news articles, scholarly journals, books on social movements, and Twitter accounts, I argue that the inaction of the government was a root cause of the movement’s change in strategies, from peaceful petitions to highly visible vandalism, and that institutional barriers prevent progress on this issue even in the current day. I demonstrate that transnational activism through international institutions such as the United Nations had a limited impact on effecting domestic change but that using social …

Work-Life And Health Experiences Of Computer Science Faculty Parents Of Children With Developmental Disabilities During Covid-19, Molly Armstrong
Butler Journal of Undergraduate Research
Prior to the COVID-19 pandemic, parents of children with developmental disabilities (PCDD) had been shown to experience more stress than parents of children without developmental disabilities (non-PCDD). COVID-19 may have exacerbated difficulties for PCDD. To compare differences in COVID-19 experiences between PCDD and non-PCDD, 202 parents working as computer science (CS) faculty reported their experiences of mental health symptoms, physical health symptoms, work-life conflict levels as experienced during the pandemic, and any changes in their childcare responsibilities because of COVID-19. Participants completed surveys on their experiences during Fall 2020 and Spring 2021, the first academic year after the start of …
Agency Actualization And Artistic Awakening: The Poetic Rhetoric Of Freedom School Students, Eden Doyle
Agency Actualization And Artistic Awakening: The Poetic Rhetoric Of Freedom School Students, Eden Doyle
Butler Journal of Undergraduate Research
This paper analyzes the rhetoric of poems written by Freedom School students in Mississippi amidst the Civil Rights Movement of the 1960s. Much of the rhetoric documented, explored, and valued from this era is of adults with the power and means to have their voices heard and respected; however, this paper argues the value of these students’ unique Black experience as one that is underexplored and greatly compelling. The social and political context surrounding the inception of Freedom Schools is discussed, as well as the need for further research and scholarship on the intellectual activity and rhetorical artifacts of the …

The Effects Of Covid-19-Induced Stress, Anxiety, And Depression On The Eating Behavior Of College Women, Natalie Simpson
Butler Journal of Undergraduate Research
Increases in the prevalence of disordered eating patterns have been linked to distress and poor mental well-being. Additionally, COVID-19 has been linked to both depressive and anxious symptomatology, along with increased feelings of distress (Fitzpatrick et al., 2020). Because disordered eating is particularly prevalent among college-age women, this study sought to determine how depression, anxiety, and stress affect eating behaviors of college women in the context of the COVID-19 pandemic. One hundred seventy-nine women, aged 18–24, at Butler University gave informed consent before completing a questionnaire pertaining to their demographics, their stress surrounding COVID, and their weight change since March …
An Evaluation Of Women’S Social Status In Colonial Hong Kong With A Feminist Lens - Case Studies, Heng Du
An Evaluation Of Women’S Social Status In Colonial Hong Kong With A Feminist Lens - Case Studies, Heng Du
Butler Journal of Undergraduate Research
Even though Hong Kong remained under British control from 1842 to 1997, denizens were not modernized in a way comparable to that of the British. To the contrary, while governing Hong Kong, British colonizers allowed continued reference to ancient Chinese customs in the area. Such policy diminished women’s chances of receiving fair treatment in matters such as property management and divorce. Unlike in Hong Kong, women were legislated to be parallel to men in matrimonial and property inheritance petitions in China, Britain, and colonial Singapore. This study is based on two exemplary cases judged by authorities in colonial Hong Kong. …

Identifying Disinformation In Scholarly Publishing, Natalie M. Mclendon
Identifying Disinformation In Scholarly Publishing, Natalie M. Mclendon
Butler Journal of Undergraduate Research
This paper examines the pro-Confederacy movement’s attempt to distort history through textbook revision to argue in favor of strengthened media literacy as a brace against the effects of disinformation and propaganda. Previous definitions of misinformation and disinformation overlap and are as yet unclear and, therefore, should be further studied. “Lost Cause” mythologists worked diligently to propagate school textbooks which portrayed skewed versions of history that cast Southern Confederates’ cause as noble and honorable while obscuring the real reason for the Civil War. While undergraduate students can rely on the CRAAP and BEAM methods of identifying problematic texts, they should be …

Studying Extended Sets From Young Tableaux, Eric S. Nofziger
Studying Extended Sets From Young Tableaux, Eric S. Nofziger
Undergraduate Honors Thesis Collection
Young tableaux are combinatorial objects related to the partitions of an integer that have various applications in representation theory. These tableaux are defined as a left-justified set of n boxes filled with the numbers 1 through n and organized in rows, with the length of each row corresponding to a summand in the partition. In recent work of Graham–Precup–Russell, an association has been made between a given row-strict tableau and three disjoint subsets I, J, and K, also called extended sets. In this project, we begin to classify which extended sets correlate to a valid row-strict or standard tableau. We …

The Patient Protection and Affordable Care Act (PPACA) is the overarching federal law that has impacted the intricacies of the health insurance market for more than a decade. Using the supervised learning method of multiple linear regression, the relationship between the medical loss ratio rebates and predictor variables such as the state, health insurance market, and the number of insurance companies owing rebates will be analyzed, along with the actuarial value of metal tiers and geographic rating area factors in terms of their relationship to the insurance premium for a standard family of four, defined as a forty-year-old couple with …
Using Nasa's Tess Mission To Search For Extremely Low Mass White Dwarf Stars, Corinna Peña
Using Nasa's Tess Mission To Search For Extremely Low Mass White Dwarf Stars, Corinna Peña
Undergraduate Honors Thesis Collection
Extremely low-mass white dwarf stars (ELM) are white dwarf stars with a mass lower than 0.45 solar masses that could not have evolved through normal processes within the lifetime of our universe. Therefore, these objects can only be created through a common envelope phase or a stable Roche lobe overflow while in a binary. These objects have periods between a few minutes to a few hours, so they are very short lived which makes them very rare. My goal for this project was to find these ELM stars by using NASA's Transiting Exoplanet Survey Satellite (TESS) data. I analyzed this …

The discovery and ability to provide an absolute concentration of biomarkers in the body can facilitate early diagnoses of diseases. This information can also be used for more accurate and unique treatments for those patients. While major advances in molecular mass spectrometry allows for a sensitive identification of these biomarkers, they are limited to only four orders of magnitude in their dynamic ranges. Due to this, detection and quantitation of low abundant proteins, which tend to make up these vital biomarkers, is very difficult. On the other hand, ICP-MS offers a wider dynamic range (up to 12 orders of magnitude) …
