Welcome & Opening Remarks
The Office of Research and Creative Scholarship serves a vital role across Andrews University in supporting and funding quality undergraduate research. The Undergraduate Research Scholar Award was established in 2002 to facilitate more opportunities for students to engage in research and creative scholarship in greater depth than required by their individual programs of study. The URS Award enables students to work closely with faculty mentors, participate in disciplinary conferences, and develop important professional skills. Many Honors Scholars have benefited from the URS funding and have noted that support on their poster boards.

Since its founding in the 1960s, the J. N. Andrews Honors Program at Andrews University has fostered enthusiastically the transformative experiences of undergraduate research. By means of the Honors Thesis, the Honors Program requires its students to engage in substantive primary investigations in which students take an active role in posing research questions, designing and refining methodologies, collecting data and results, and critically analyzing the significance of their conclusions.

A team of highly engaged faculty research mentors makes possible a rigorous program of undergraduate research. We thank each mentor for the commitment of time and energy invested in Andrews University’s young scholars.

Thank you for being part of the Andrews University Undergraduate Research and Honors Symposium 2021.

The Distribution of Food Preparation Artifacts in Field D at Tall Jalul, Jordan
Video: Click here

Abstract
The Andrews University Institute of Archaeology Madaba Plains Project houses many of the artifacts that were found, recorded, sketched, photographed, and brought to the Siegfried H. Horn Museum for further research. These artifacts are then used to help archaeologists understand the history of the Madaba Plains, Jordan, and its significance to the Bible. Food preparation artifacts like grinders, pounders, mortar and pestles, and stone bowls, are some of the most frequently excavated artifacts at Tall Jalul. This poster examines the relationship between domestic living spaces and food preparation artifacts suggesting that the concentration and distribution of these artifacts can give us insight into the use of certain domestic living spaces found in Field D Squares 1 and 3.

Comparison of Enamel Microstructure of Ictidomys Tridecemlineatus Formed During Hibernation Versus the Active Season
Video: Click here

Abstract
Ground squirrel incisors grow continually, preserving a record of their most recent weeks of life. Previous research demonstrated that an abnormality in the surface of incisor enamel and dentin of thirteen-lined ground squirrels (Ictidomys tridecemlineatus) corresponded with hibernation. Using scanning electron microscopy, we compared internal microstructure of incisor enamel deposited during and outside of hibernation to determine if external disruptions corresponded to differences in internal microstructure. However, after documenting microstructure for several incisors, we did not observe microstructural differences. Thus, the surface abnormalities of incisor enamel that form during hibernation are not associated with abnormalities in internal enamel microstructure.

Finding optimal OPA-IBLC Derivatized Amino Acid Analysis Parameters with 3-dimensional Fluorometric Scans for HPLC Method Validation
Video: Click here

Abstract
This research validates RP-HPLC fluorimeter and OPA-IBLC derivatization parameters to lower limits of detection (LOD) and quantitation (LOQ). A 3-dimensional fluorometric scan in pH 10.4 sodium borate buffer showed peak OPA-IBLC derivatized histidine and glutamic acid fluorescence occurs at 368- to 445-nm and 336- to 452-nm λ¬ex-λ¬em, respectively. HPLC-FLD response was refined with systematic FLD analysis in pH 4 sodium acetate buffer after column separation. Derivatization reaction completion was ensured by increasing injector mixing time until peak integration area stabilized. Results inform future FLD parameters and determine racemic OPA-IBLC derivatized amino acid ratios in ostrich eggshells.

An Artificial Intelligence Approach to Mancala
Video: Click here

Abstract:
Through the study of popular games such as Chess and Go, countless artificial intelligence (AI) research has been conducted in an attempt to create algorithms equipped for adversarial search problems. However, there are still a plethora of avenues that offer insight into further development. Mancala is traditionally a two-player board game that originated in the East and offers a unique opponent-based playing experience. This thesis not only attempts to create a competitive AI algorithm for mancala games by analyzing the performance of several different algorithms on a number of mancala variations, but it also attempts to extract applications that may have relevance to other “game-solving” AI problems.

Thank you for your interest in the Artificial Intelligence Approach to Mancala. We regret this session is no longer available. We invite you to engage with some of our other students during this time.

One Writer, Two Genres: Composing and Analyzing Creative Non-fiction and Fantasy
Video: Click here

Abstract
Creative writers face a wide range of options when they sit down to craft art out of words. Available to them are many genres, each with their own characteristics or traits. Additionally, many writers have accomplished self-reflection in interviews, Q&A sessions, and in print. It is not unusual to find writers taking their craft and turning it into their subject matter. This project aims for the same. In order to analyze the similarities and differences in the writing process across genres, a “writing about writing” essay is included along with four creative non-fiction essays and a young adult fantasy novel draft.

The Effect of Synchronous Egg-laying on Gull Population Dynamics While Tracking the Egg-laying Order
Abstract
During years of high sea surface temperature, food resources for glaucous-winged gulls (Larus glaucescens) are scarce. In response, male gulls cannibalize the eggs of neighbors. When this occurs, female gulls in dense areas of the colony adopt a tactic called egg-laying synchrony, in which they lay eggs synchronously on an every-other-day schedule. Field observations show that the first-laid egg of each clutch is the most likely to be cannibalized. We analyzed a mathematical model of egg-laying behavior that tracks egg-laying order and found that the system begins to oscillate synchronously when the colony is sufficiently dense. We demonstrated that synchronous colonies produce more eggs than
non-synchronous colonies in the presence of cannibalism.

Determining the Origins of Helix Glitches in LIGO’s H1 Detector
Abstract
The LIGO detectors are ultra-sensitive, making them susceptible to glitches from the noise that can block gravitational wave signals. In order to reduce the number of glitches that occur in the detector, the cause of the glitches must be found. I am researching the Helix glitch to try and determine its origin. This is accomplished by studying the times at which the glitch occurred in the detector and then looking for factors that may have caused a glitch to happen around the same time, to see if there are any correlations.

Selective induction of apoptosis by aqueous extract of Chinese medicinal herb Scutellaria barbata in HCT-116 colon cancer cells and CCD-841 colon epithelial cells.
Abstract 
Scutellaria barbata (SB) has been used in traditional Chinese medicine for treating liver, lung and rectal tumors. We previously found that aqueous extracts of SB inhibited mutagenesis, DNA binding, and metabolism of aflatoxin B1 and benzo(a)pyrene. They were also shown to inhibit foci formation in the colon of AOM-induced mice. Other research demonstrated that ethanol extracts inhibit colorectal cancer growth, inhibit proliferation and induce apoptosis. In this study, the effects of aqueous extracts of SB on the induction and modulation of apoptosis in HCT-116 colon cancer cells and CCD-841 normal colon epithelial cells were assessed using TUNEL assay, Apoptosis/Necrosis Detection Kit, and Human Apoptosis Antibody Array. Our findings suggest that SB possess a wide range of antitumor activity and may be a useful drug for treating colon cancer.

Sexual Orientation, Substance Misuse, and Sexual Misconduct at a Conservative Christian University
Video: Click here

Abstract
College students in general tend to have high rates of substance use and abuse. Sexual minority college students show high rates of substance use and abuse. These findings are consistent across studies of sexual minority students and their relation to substances. Sexual minority populations are also more at-risk for becoming victims of sexual harassment and assault. Minority stress theory hypothesizes that LGBTQ+students at Christian universities may face heightened stigmatization or alienation, perhaps because of Christian norms/beliefs supporting heterosexual orientation.

Abstract
The decrease in water quality for environmental and drinking water has been prevalent in the Great Lakes region, where industrialization, agricultural development, and population increase have contributed substantially. Looking through historical reports and the present, the degradation in water quality will likely continue. Our research intends to use inductively coupled plasma atomic emission spectroscopy to create a methodology to quantitatively detect various heavy metals and other elements from any water source. Current research has been on the determination of a niche in water testing and the creation of an infographic, as well as data of simple water samples.

Enamel Corrosion Levels on Squirrel Teeth from the Fox Canyon Locality, Pliocene of Kansas
Abstract
The enamel of teeth may be corroded after death, especially if the teeth pass through the digestive tract of a predator with low gastric pH. This study characterized enamel corrosion of fossil squirrel teeth from two species (Otospermophilus rexroadensis and Ictidomys meadensis) obtained from the Fox Canyon locality of Kansas. Using microscopic imaging, I categorized teeth based on corrosion level. For both species, over 40% of specimens exhibited heavy to extreme corrosion, suggesting gastric digestion. There was no significant difference in the distribution of corrosion categories between both upper and lower teeth of either species. Furthermore, there was no difference in the distribution of corrosion categories between the two species.

Copper (II) Sequestration by PAMAM Dendrimers in Tap Water
Abstract
Dendrimers are nanomaterials that are widely studied for a variety of applications because of their distinctive properties. One such property of, specifically, the generation 2-PAMAM Dendrimer is its particular affinity for copper (II) ions. This could be influential in selective heavy metal extraction, particularly in contaminated water. Our research aims to test the sequestration and selectivity of PAMAM dendrimers with amine surface groups for copper (II) ions in a chemical environment with interfering species, such as tap water, using Inductively Coupled Plasma spectroscopy. Ongoing research has involved developing methods for dendrimer extractions and creating calibration curves for standards to ensure accurate and reproducible results.

Silver Nanoparticle Synthesis by Microwave and Non-microwave Methods Using Hydrogen Gas as a Reducing Agent
Video: Click here

Abstract
Synthesis and characterization of silver nanoparticles are of current interest. This research project describes a simple and rapid synthesis of silver nanoparticles upon reduction of Silver(I) oxide (Ag2O) by molecular hydrogen. The production of nanoparticles can be achieved by purging a solution of Ag2O and water with hydrogen gas and heating for a maximum of two minutes using a common kitchen microwave. This reaction generates nearly naked silver colloid that contains no foreign stabilizers other than metal particles and water species. Its application is then evaluated with biological cultures to test for the antibacterial effects of the made particles.

Synthesis of 5-Membered Ring Heterocycles for Alzheimer’s Disease
Video: Click here

Abstract
The progression of Alzheimer’s disease (AD) is correlated to the degenerative activation of muscarinic acetylcholine receptors (mAChR) located in the brain. They are a family of five G-protein coupled receptors, (M1-M5), linked to functions within the central and peripheral nervous system.1 More specifically, activation of M1 with positive allosteric modulators (PAM), have shown to bind to the allosteric pocket and slow the degenerative process of AD with minimal intrinsic effects.2 Structural motifs of potent PAM activity and weak agonism proposed a synthesis of an isooxazoline compound, incorporating a 1,3-dipolar cycloaddition. The core motif of the proposed isooxazoline structure has been created and further synthesis of the pendant and top is required.

Variational AutoEncoders for Biosensor Data Augmentation
Abstract
Over the past decade machine learning and artificial intelligence’s resurgence spawned the desire to mimic human creative ability. Initially attempts to create images, music, and text flooded the community, though little has been learned regarding constrained, one-dimensional data generation. This paper demonstrates a variational autoencoder approach to this problem. By modeling biosensor current and concentration data we aim to augment the existing dataset. In training a multi-layer neural network based encoder and decoder we were able to generate realistic, original samples. These results demonstrate the ability to realistically augment datasets, improving training of machine learning models designed to predict concentration from input signals.

An Egyptology-Informed Exegetical Analysis of Psalm 90 with Creative Applications
Video: Click here

Abstract
While scholars continue to debate Egyptological influence in the Torah, few recognize or acknowledge it in the Psalms, though the superscription of Psalm 90 does indicate Mosaic authorship. This project first examines the structure and significance of the Egyptian nuances within Psalm 90, and proposes an approximate time of composition relative to Moses’s life. Following a study of the historical context, I craft a well-researched fictional narrative that aims to immerse young-adult readers in the world of the psalm. This project draws connections between Moses’s struggles and those of a modern audience, foregrounding insights discovered during an extensive process of exegetical and historical research.

Abstract
Every student at Andrews University who does not have a satisfactory math placement must review prior math concepts before taking general education math courses. Our research seeks to answer which misconceptions are persistent on linear equation questions. Our findings report that many errors in student work can be remedied by more focus on basic linear concepts, such as what slope means, and how points are plotted. We hope our results will guide us as we make substantive and positive changes to the remedial math curriculum with the goal of maximizing student comprehension while still maintaining a level of individualized learning.

Abstract
The world of opera is beautiful but often marred by the historical ideas and accepted practices of the times in which works were created. This project is a consideration of the history of Orientalism in opera and the current discourse on Orientalism and cultural appropriation. I will be focusing on the historical context of cultural appropriation and current trends for responding to the same in the performing arts, with attention to the dynamics of gender and place in several of the selected operatic works, consideration of the problem of whiteness in opera, and the resulting issues of cultural appropriation and impersonation.

An Information-Theoretical Approach to Analyzing Magnetosphere-lonosphere Coupling Process in Hybrid Simulations.
Video: Click here

Abstract
Recent simulations of tail dynamics using the Auburn Global Hybrid Code in 3-D (ANGIE3D) suggest that tail flows are closely related to the dynamics of Alfven waves propagating from the magnetotail to the ionosphere. To understand the dynamical coupling process described by the simulation, we consider the simulated time series of plasma sheet structures associated with tail flows and the Poynting flux into the ionosphere. We present 2-D and 3-D plots showing how the ionospheric Poynting flux responds to activity in the plasma sheet over time and the location at which Alfven waves are generated. We utilize transfer entropy [Schrieber, 2001] to identify causal, non-linear relationships among reconnection events, tail flows, and Poynting flux into the ionosphere. Results suggest that flows in the plasma sheet are the primary driver of the Poynting flux, which is consistent with expectations. This work demonstrates how system science tools can be used in conjunction with complex simulations to describe the underlying system dynamics and provide a framework for understanding the interrelated components, functions, and causalities in the system.

Parental Stress and Feelings of Support by Speech-Language Pathologist of Children Receiving Speech and Language Services: A Correlational Study During COVID-19
Video: Click here

Abstract
Due to COVID-19 parents have been thrown into the role of teacher, tutor, playmate, and parent. For parents of children with communication disabilities, they may also feel like they have to become a speech-language pathologist. We are in a period when parents have a higher desire to receive help, but there is less help being given by social service providers. This study seeks to investigate the stress levels of parents with children who have been diagnosed with a communication disorder and if these parents feel supported by their child(ren)’s speech-language pathologist during COVID-19. This will be determined using a simple survey containing 56 questions, 18 of which are from the Parental Stress Scale. The purpose of this study is for speech-language pathologists to better understand parental needs and continue to devise plans to better assist parents during these difficult times.

Emergence of entrepreneurship in Transjordan during the late Ottoman empire
Abstract
How did Ottoman policies influence the emergence of entrepreneurship among elites in Transjordan from circa 1850-1914? During the late Ottoman period, there was an economic transition from subsistence farming and herding to the development of large-scale, for-profit farms, privately owned by elites. The current study hypothesized Ottoman government policy prioritizing cash crop farming over subsistence farming and nomadic living created conditions that allowed elites in Jordan to develop entrepreneurship. To measure my dependent variable, entrepreneurship, I adapted Rostow’s Stages of Economic Development. To track my independent variable, Ottoman influence, I created a scale. From the thematic analysis of two case studies, my hypothesis was supported and expanded upon.

The Effect Of Clay On The Inhibitory Effect Of Mustard Seed Meal On Velvetleaf Seedling Growth
Video:  Click here

Abstract
Mustard seed meal (MSM) has been studied as a biofumigant that suppresses weed growth organically. Previous studies have shown that MSM in soil with a higher sand content was highly effective in suppressing the germination of weeds, and that as clay/silt in sand content increased, MSM effectiveness decreased in suppressing seed germination. Based on these results, it was postulated that clay may have effects on MSM by inhibiting it from suppressing weed growth. Two different types of pure clay--kaolin and montmorillonite--were selected to test at various concentrations. Low concentration of clay in MSM does not seem to have effect on inhibiting the weed suppressive properties of MSM.

Abstract
Exposure to heavy metals such as mercury, lead, and arsenic can negatively affect the structure and function of cells, tissues, and organs. Such heavy metals can be excreted from the hair as metabolic products during its growth process thus hair analysis is thought to be a reliable indicator for the environmental accumulation of heavy metals. Our research aims to develop a methodology to quantify heavy metal concentrations found in biological samples using Inductively Coupled Plasma Spectroscopy. Current research involves preparing hair samples for analysis and creating calibration curves for heavy metals through a process that is accurate, precise, and easily replicated.

Optimizing Fluorescence PMT Gain and Excitation Wavelength for HPLC DL-Amino Acid Detection
Abstract
Amino acids exist as enantiomers that can be separated and detected using HPLC-FLD. An optimal PMT gain and wavelength of excitation must be determined to lower the limit of detection (LOD) and quantitation (LOQ) as increasing the PMT gain amplifies the signal on the HPLC-Spectra. The HPLC-FLD spectra of OPA-IBLC derivatized histidine was measured at PMT gain 5 and 7 for the excitation wavelengths of 340-, 260-, and 240- nm. Hence, the optimal excitation wavelength and PMT gain can be determined by comparing the fluorescence spectra.

Abstract
Compartmental modeling is a method of employing math to create visual representations of a disease interacting with a select population, typically used in epidemiology analyses. This project applies and adapts compartmental modeling equations to data collected on the deaths, infection, and testing of COVID-19 in Michigan. Comparing current data to past predictive models, as well as the visual representations that were developed through the various compartmental modeling methods, allows assessment of the effects of the preventative measures taken by the state, the various rates at which the infection is able to spread, as well as the potential path and spread of the virus in the future.

Anarchism and Masculinity in Homer’s Iliad & Doran’s Troilus and Cressida
Video:  Click here

Abstract
This interdisciplinary project employs political philosophy from Stirner, Hobbes, and Nozick to conceptualize the masculinities and politics present in Homer’s Iliad and Doran’s Troilus and Cressida. By observing the one-to-one, male-male dominance hierarchies present in Homer’s text, Stirner’s Ego aptly explains Achilles’ rejection of these aforementioned hierarchies. Similarly, Doran’s RSC production draws inspiration from Mad Max: Fury Road, which opens the play up to Hobbesian state of nature theory and subsequently Nozick’s theory of protective associations. Fundamentally, this political philosophy guides a larger discourse regarding the RSC’s treatment of heroic masculinities and its consequences for the RSC’s younger, male audience.

Abstract
The snake cube is a popular puzzle that has been analyzed for its computational difficulty and shown to be NP-complete. Conceiving of the puzzle as a Hamiltonian path in an n×n×n graph, we offer a novel mathematical analysis by considering invariants of the puzzle. This allows us to determine necessary conditions for a particular snake cube to be solvable and eliminate a large class of possible puzzles as unsolvable. In particular, we establish upper and lower bounds on the possible number of straight components in solvable snake cube puzzles which exactly determines the number of maximal straight components in the classical 3×3×3 puzzle.

Producing Music Using Negative Harmony
This project uses Negative Harmony as a basis and reference point for producing original songs in the style of
instrumental jazz and funk. Negative harmony is a loose term that describes a technique of reharmonization made popular by musician Jacob Collier. While negative harmony is best understood as a reharmonization technique, I am essentially writing new songs with chord progressions that strive to replace common chord progressions with their negative harmony counterparts. I ultimately seek to make music with unconventional but viable harmonies and grow as a musician in the process.

Information Horizon of Stellar Flares
Video: Click here

Abstract
Because the dynamics of stellar flares are modulated by magnetic activity cycles, they provide a window to the underlying dynamics. Using mutual information, we compare the process that creates stellar flares with a nonstationary Poisson process. From the stellar intensity data collected by the Kepler satellite, we designate flare events based on a sudden elevation in the intensity above a given threshold condition. The waiting times are calculated as the time difference between flare events, and surrogate datasets are constructed using the flare rate as a function of time. When the mutual information of the time-lagged waiting time distribution is plotted for both the original and surrogate dada, an increase in the mutual information is present for the original data as compared to the surrogates, indicating that there is short term memory stored within the stellar flare-producing process.

The Impact of Technology on the Developing Visual and/or Auditory Memory in School Aged Children

Video: Click here

Abstract
This study aimed to determine whether time spent on technology impacts the developing auditory or visual memory in school-aged children. A survey was completed with the child participants to acquire a catalog of time spent on both technology devices and non-technological activities. Tests included a visual and auditory memory assessment adapted from the Preschool Language Scales Fifth Edition (PLS-5). The subtests were expanded upon in order to incorporate an auditory element. The results indicated that there was no significance between time spent on technology and visual and auditory memory scores. This was likely caused by the small sample size. However, the researchers did find that the auditory mean scores were significantly different from the visual mean scores across the participant’s age range. Consequently, the researchers believe that this area of research could benefit from a similar study with a larger sample size, for specifically the technology element, that continues to assess how auditory and visual memory compare across this age range.

Is there a strong relationship between problematic mobile device use and cognitive failure in adults? If so, does that relationship remain when controlling for psychological well-being? In two samples of American adults, psychological well-being and distress accounted for over 70% of variance in everyday cognitive failures, as did problematic mobile device use. However, when controlling for psychological well-being, problematic mobile device use accounted for an additional 2% of variance. Well-being and device use overlap in relationship to cognitive failures.

Abstract
Phonotaxis can be defined as the movement of organisms in response to an auditory stimulus. It plays an important role in helping an animal find a potential mate. Thus, it is worthwhile to understand what factors may influence it. This study investigates possible changes in phonotaxis of young females when raised with males but not allowed to mate. Preliminary results show a significant difference in the behavioral response of young male-exposed females when compared to those of virgin females. These results suggest that factors other than mating may alter the female’s response and its underlying neural elements that control behavior.

PAMAM Dendrimer Synthesis Optimization Through Reaction Kinetics
Video: Click here

Abstract
The goal of this project is to optimize PAMAM dendrimer synthesis reactions by studying their kinetics. PAMAM dendrimers are produced by reacting methyl acrylate with ethylene diamine, so determining the best reaction conditions for these compounds will help improve dendrimer production. Controls for reactant feed rate and reactor cooling are to be used so that the determined ideal conditions can be maintained. This has the benefit of requiring less processing time as well as improving the ease with which the reaction can be monitored by a researcher.

Synthesis of Novel Temozolomide-Fatty Acid Imide Hybrid Compounds for the Chemotherapeutic Treatment of Glioblastoma Multiforme
Video: Click here

Abstract
Glioblastoma multiforme (GBM) is an aggressive form of brain cancer that originates from glial cells, which make up the supportive tissue surrounding neurons. Temozolomide (TMZ) is the current chemotherapeutic drug administered to treat GBM as it works to inhibit the growth of the cancer cells. This research study focuses on developing a method for synthesizing novel hybrid compounds that combines TMZ with various fatty acids known to have anticancer properties, forming a series of imide compounds with potential chemotherapeutic effects. Once the novel hybrid compounds are successfully synthesized, they will be tested for their anticancer properties on glioblastoma cells.

Playing for the "Father of Lights" The musical philosophy of Pedro Eustache
Abstract
Known for his multidimensional and interdisciplinary work with notable musicians such as Yanni and Hans Zimmer, Venezuelan-American flutist and instrumentalist Pedro Eustache has mastered an astounding number of woodwinds and musical styles during his lifetime, from jazz to classical to several genres of global music. What is less known about him, however, is that he is a devoted Christian whose faith deeply influences his artistry and work ethic. The current project seeks to be the first scholarly exploration of Eustache's philosophy of music through an examination of published interviews, essays, and videos found online and in the musical press.

Graduate Students’ Perceptions of Multicultural Counseling in Communication Sciences and Disorders
Video: Click here

Abstract
The United States is becoming a more culturally and linguistically diverse country. However, despite this increase in the cultural diversity of the US only 7.9% of speech-language pathologists identify as racial minorities compared to 28.6% of the US population that identifies as such. A national survey of practitioners indicated that the majority of speech pathologists did not feel fully qualified in the area of cultural competence. As the needs of the US population diversify, the need for strong abilities in Multicultural Counseling (MC) in the field of Communication Sciences and Disorders are necessary. This study assesses the exposure of students in the Masters of Speech-Language Pathology program at Andrews University to observe their perceptions of MC in the field, exposure to MC in their curriculum, and their comfort of engaging in MC in the clinical setting. It is important to see the perceptions of MC in graduate students before they enter the field to see if the next generation of speech pathologists are receiving the proper training they need in MC in graduate school.

Socioeconomic Status and Ethnicity as Predictors of Childhood Career Aspirations
Abstract
Children discuss their career aspirations from an early age. Studies suggest that there is a relationship between income level and career aspirations. However, there is a gap in the literature that examines relationships between socioeconomic status, ethnicity, grade level, and career aspirations. This study aims to investigate these relationships by surveying students in grades 3, 6, 9, and 11, from diverse neighborhoods. Focusing on students from predominantly Black and White and low and high socioeconomic schools will allow us to discover if there are multilevel relationships among those variables.
