School Standard
Adrian Montenegro
Neglecting the importance of student education only serves to decrease the morale amongst students. These new implementations are only reminders of the danger present in today’s schools. Unfortunately, communities are never the same after a tragedy, impacting generations to come. Why are students still being punished after the tragedies.

Nuclear Power Plant in Las Vegas
Ryan W. Murray
This research focuses on the impact of a “Nuclear Power Plant in Las Vegas” or ‘NPP in LV’ for short. Nuclear power is clean, has no greenhouse gas emissions, and has a moderate cost of kilowatt hours. Las Vegas, or more specifically Clark County uses Gas power plants to produce a majority of their electricity. My project will show what a nuclear plant could do if built in the city of Las Vegas. What is a Nuclear power plant? The EIA’s definition is “A nuclear power plant uses the heat that a nuclear reactor produces to turn water into steam, which then drives turbine generators that generate electricity” (U.S. Energy Information Administration, 2020). Currently the U.S. uses two types of nuclear reactors, either Boiling-water or Pressurized-water nuclear reactors. The most used currently is the Pressurized-water reactor. EIA explains “A steam generator is a giant cylinder filled with non radioactive water (or clean water). Inside the giant water-filled cylinder are thousands of tubes filled with the hot radioactive water from the reactor core that eventually bring the clean water to a boil and turn it into steam. The radioactive water flows back to the reactor core to be reheated, and once reheated, returns to the steam generator” (U.S. Energy Information Administration, 2020). The main advantage of the pressurized water reactor is that it will only contaminate a fixed amount of water which is constantly reused inside the system.

Climate Change Hope Scale: Factor Analysis in an Adult Sample
Gemma Ortega, Steven J. Glover, Jesse Tabaczynksi, and Orei Z. Odents
Willpower - how much individuals believe that set goals can be met. Waypower - the extent to which individuals can think of strategies for accomplishing those goals.
The Climate Change Hope Scale (CCHS; Li & Monroe, 2017) was designed to measure three aspects of hope: 1. Personal sphere willpower and waypower (WP) 2. Collective sphere willpower and waypower (CW) 3. Lack of willpower and waypower (LW).
A three-factor model fits the CCHS among adolescents. The purpose of our study was to determine if the three-factor model fits the CCHS in adults.

The Effect of Sleep and Emotion on Pattern Separation
Alanna N. Osmanski and Laisha Sanchez Espitia
Slow wave sleep has been considered an important aspect of memory consolidation, most commonly through a model known as active systems consolidation. Newly encoded memories are repeatedly activated, driven by slow oscillations that occur in the neocortex. A widely accepted view is that emotional memories are preferentially consolidated during sleep making them easily obtainable for retrieval. However, recent meta-analyses of sleep, emotion, and memory have suggested that this effect may not be as robust as we once thought. A relatively new way to investigate sleep and emotional effects on memory is with a pattern separation task called the Mnemonic Similarity Task (MST). The current study examined pattern separation and item recognition using an emotional variation of the MST consisting of negative and neutral images.

Antibiotic Production of Facultative Anaerobic Bacteria from Soil Isolates
Cierra Paaaina-Daquioag and Debra Kerr
In nature, antibiotics are produced by organisms to deter and possibly communicate with other organisms. The use of antibiotics to treat infections revolutionized medicine, but bacteria and fungal pathogens become resistant due to the overuse of these medications. A potential solution is to search for novel antibiotics produced by soil bacteria. Bacteria gene expression patterns, including antibiotic production, are different under aerobic and anaerobic conditions. The objective of this research project was to identify soil bacteria that produce antibiotics that inhibit the growth of benign relatives of the ESKAPE pathogens under aerobic and anaerobic conditions. A secondary objective was to adapt the results for a microbiology course-based research experience in the School of Life Sciences.

Synthesis of Modified Walnut Shell Biochar and Material Characterization in Ground Water Treatment
Maaike Parajes and Suraj Pochampally
Biochar (BC) is a carbon-rich material synthesized from the pyrolysis of biomasses and developed to remove soil and wastewater contaminants. The pyrolysis process involves thermally decomposing the organic materials in the absence of oxygen. Biochar has the potential to be an eco-friendly and effective adsorbent for heavy metals and toxic organic compounds. An adsorbent is a material that attracts other substances on its surface, chemically and physically. Walnut shells were chosen for the biochar modification to improve the surface morphology, pore structure, and adsorption capability.

Exporting U.S. Cosmetics to China's Lower-Tier Cities
Kaitlynn Quach and Audrey Stephanie
What is the cosmetics market like in China's lower-tier cities for U.S. brands? In order to create market entry strategies, China has city-tier classifications that are commonly used in business. Classifications are based on GDP, political administration, and population. In 2020, Chinese consumers spent more than ¥340.0 Billion RMB ($53.46 Billion) on cosmetic products. This number increases from year to year and is especially affected by globalization. The United States is one of the top exporters of cosmetics brands.
Although popular, United States cosmetics brands face strong competition in China's first-tier cities. First-tier cities are considered the largest and wealthiest cities in China. Beijing, Shanghai, and Hong Kong are some of the most well known first-tier cities.
On the other side, China's lower-tier cities are less populated and have a smaller GDP. With the growth of lower-tier cities in China such as Guilin and Hulin, there may be more opportunities to gain awareness, market share, and loyal customers long-term.
This research explores the benefits of exporting U.S. cosmetics brands to lower-tier cities in China. All personal care products are referred to as cosmetics.

The Meta-Mood Experience: Exploring the One-, Three-, and Four-Factor Models of the Trait Meta-Mood Scale
Zain N. Raja, Jerald J. Novero, Susan E. Gutierrez, Orei Z. Odents, and Fitsum A. Ayele
The meta-mood experience involves "thinking about mood, examining the relation between mood and thoughts, maintaining good moods, and altering bad moods" (Mayer & Gaschke, 1988). Meta-mood can help individuals have a better grasp of what they are feeling at different times.
The 30-item Trait Meta-Mood Scale (TMMS; Salovey et al., 1995) measures the extent to which people attend to, distinguish among, and regulate their mood and emotions.
Salovey et al. (1995) found three factors (Emotional Attention, Clarity, and Repair), while Palmer et al. (2003) found evidence for a fourth but left it unnamed.
We named the fourth factor in our study Emotional Susceptibility because this factor looks at how easily influenced the participants are in regard to their mood and emotions.
Censoring occurs when the value of a variable is only partially known (Gijbels, 2010). If there are a significant number of people that are scoring 1 on an item, there could be left-censoring. This is because low scores on the item fail to reflect low levels of the dimension that is being measured.
Our study aimed to determine whether the one-factor, three-factor, or four-factor models fits the data the best when we assumed that participants may have censored values on some of the TMMS items.

Musicality, Misophonia Sensitivity, and Responsiveness to Misophonia Videos
Alexis Rice, Jennifer Hsu, Kaela Omengan, and Sivan Barashy
Misophonia sensitivity as measured by the A-MISO-S predicts emotional responses to misophonia trigger videos, but musical sophistication (Gold MSI scores) did not. A measure of real-time responses to videos can capture a meaningful aspect of misophonic experience in the general population. Future research should investigate whether more direct measures of musicality such as perceptual tasks will show a relationship between musicality and misophonic reactions.

Misophonia Sensitivity is Related to Enhanced Responsiveness to Misophonia, ASMR and Musical Frisson
Alexis Rice, Kiara O'Keefe, Kacey Chang, Sivan Barashy, Solena Mednicoff, and Destiny Gonzales
Misophonia: a condition in which specific everyday sounds (e.g., chewing, breathing) trigger an atypical, negative emotional response.
ASMR: a sensory phenomenon triggered by stimuli that induce a state of relaxation, positive feelings, and tinging sensations that spread from the head to the rest of the body.
Musical frisson: typically characterized by positive affect and strong physiological reactions, such as shivering, goosebumps, and teary-eyes in response to highly pleasurable music.

Localization of IPMK
Braden Sio
Inositol Polyphosphate Multikinase (IPMK) is a relatively new gene found in mammalian cells. To determine where I should further conduct our research, I localized this gene within HEK-293 cells. For this study, HEK-293 cells are used. These cells are easily cultured and transfected, both of which are needed for this study. IPMK tagged with Green Fluorescent Protein is transfected into our test group. The control group is transfected with only Green Fluorescent Protein. After transfecting the HEK-293 cells, the cells are put under a fluorescent microscope under the GFP setting. In the HEK-293 cells that were transfected with IPMK GFP, the visible green fluorescence appeared within the nucleus of the cell. In the HEK-293 cells that were transfected with only GFP, the whole cell was seen with green fluorescence. With this information, I conclude that IPMK is localized within the nucleus of the cell, thus giving the information on where I should begin my research on this gene.

"We Could and Should be Doing More": Domestic Violence Advocates' Perceptions of Agency Training
Elia Del Carmen Solano-Patricio and Shon M. Reed
Domestic violence advocates are an under-represented part of the criminal justice system. Because of the role that advocates play in supporting diverse populations of victims/survivors, it is important that they be given the opportunity to express their needs regarding onboarding and supplemental trainings. The current study gathers qualitative data from domestic violence advocates around the United States and explores advocates' recommendations for future trainings. Participants generally expressed the need for increased training regarding various victim sub-populations (e.g., LGBTQ+). Future policy implications and avenues of research will be presented.

The Influence of Unitization on Recognition Memory
Ting Tong, Amaya D. Bolling-McDevitt Hernandez, Audrey Kirsch, and Alanna N. Osmanski
Previous research on recognition memory assumes that associative recognition relies on recollection, whereas item recognition relies on a combination of recollection and familiarity. Unitization refers to the encoding strategy where two separate items are perceived as a single coherent entity or object. Research has demonstrated that unitization can facilitate familiarity-based recognition by generating representations of the stimulus and integrating it into a unified whole. To investigate this issue, we examined the effect of unitization on memory for word-pairs through two types of tests:
Associative Recognition: judge whether word pairs occurred together
Item Recognition: judge whether single words are old or new.

Characterization of the thermophilic xlanase Fsa272 from Candidatus Fervidibacter sacchari belonging to glycoside hydrolase family GH10
Nicole Torosian, Jonathan K. Covington, Allison M. Cook, Nancy O. Nou, and Jan-Fang Cheng
Candidatus Fervidibacter sacchari is a novel, facultatively anaerobic, hyperthermophilic bacterium found in terrestrial geothermal springs globally. Its genome encodes 115 putative glycoside hydrolase enzymes that are predicted to hydrolyze glycosidic bonds between carbohydrates. Fsa272, a member of the glycoside hydrolase family 10, was synthesized and cloned into Escherichia coli strain T7 Express. The transformed E. coli was grown with LB broth and ampicillin at 37°C. Fsa272 expression was induced with isopropylthio-beta-galactoside (IPTG), and the lysate was heat purified for 15 minutes at 80° C. The 3,5-dinitrosalicylic acid assay identified xylanase activity with a pH range of 4.5 to 10.5 (pHopt 5.5) and a temperature range of 60 to 90°C (Topt 80-90°C). The para-nitrophenol assay was used to determine the Michaelis-Menten kinetic parameters of Fsa272, resulting in KM of 1.8 mM and V max of 232.6 μM/min. The characterization of Fsa272 provides critical information on Ca. F. sacchari and its potential application in converting polysaccharide waste to biofuels.

Low-Cost Adsorbent for Disinfection Byproduct Removal from Drinking Water
Savanna Vacek and Suraj Pochampally
Disinfection byproducts (DBPs) are harmful contaminants that are unintentionally created in disinfected water after chlorination. Activated carbon, often expensive and difficult to acquire in low-income and rural areas, has previously been used to remove DBPs from drinking water. Biochar is made from agricultural waste (i.e. feedstock) and has been identified as a low-cost yet effective adsorbent to remote contaminants from drinking water. This work focuses on the efficacy of biochar and activated carbon to remove DBPs from drinking water for the purpose of treating drinking water after emergency chlorination. This study has the potential to help water distributors and disadvantaged communities improve water quality and prevent unintentional harm caused by DBPs.

Dance, Gender, and Development
Samantha J. White
Gender socialization tends to entail differential encouragement of boys and girls in different activities. Parents may encourage girls to pursue activities like dance, whereas boys are encouraged to pursue sports. Recent evidence has shown links between rhythmic and phonological abilities, and improving rhythmic ability may have positive effects on reading ability.

French Jewish Citizenship of the Late 18th to Early 19th Century
Jourdin Wilson
Results show that regions/origins influenced how French Jews felt about their citizenship, and how they were treated: (1) “The Jews of Bordeaux and Bayonne enjoyed the most advantageous legal status,” who had “Marrano origins” and acted as Portuguese merchants, made up Sephardi Jews in France (Hyman 1998, “Chapter One”). (2) Napoleon’s methods greatly influenced Jews’ citizenship. Limitations: finding English translations, understanding anti-Semitism. Future Research: (1) Findings suggest that researching particular groups or regions of French Jews leads to more varied and nuanced perspectives, rather than generalizing. (2) Choosing a region and study a particular community of Jews in France.

Dance Experience Affects Tempo Perception
Jasmine Xu, Jordan E. Hayes, Cole Smithers, and Jared Leslie
In music, the word “tempo” refers to the speed or pace of the music (the number of beats per minute, for example). Tempo is surprisingly subjective, given that beat perception depends on age and cultural experience. Other factors besides beat (like the density of events per unit time) might influence how fast or slow people dance to music. Certain styles of music afford different speeds of dance, even when their tempos are the same.

Most Impactful Years of the Yemeni Civil War
Adam Abdalla, Abhinav Dagar, Jacob Gross, Noah Myers, and Kimberly Nehls Ph.D.
The Yemeni civil war that started in 2014 has ravaged the country and has led to a surge of negative changes in living conditions throughout the area. Many different events throughout the seven-year war have led to harsh conditions to still be prevalent throughout the country. It is hard to pinpoint what years of the war had the most effect on the society’s well-being. Using data from the Yemen Data Project, it was possible to find what years of the war were the most violent, and compare that data to the GDP of Yemeni people, the number of undernourished people in Yemen and the average dollar amount of aid the Yemeni people require per year. Results showed that despite the beginning years of the war being the most violent as the most airstrikes were being dropped, the conditions of Yemeni people continue to get exponentially worse despite a heavy drop in the amount of airstrike attacks against them. Lack of military clashes has not led to better conditions that deteriorate day by day. The vast intensity of the first few years of the war were so devastating that they created a ripple effect in which the infrastructure of the country was heavily damaged, leading to a situation that will need much assistance to repeal the effects of the most impactful years of the war.

Analyzing the Gender Pay Gap at the University of Nevada, Las Vegas
Caren Abourjeily and Peter Grema
The gender pay gap has been a persistent issue within many professions, including academia. This study examines the gender wage gap within UNLV for the tenured and tenure-track faculty belonging to the College of Liberal Arts, College of Sciences, and the Lee Business School. This study controlled for variables such as department, rank, time, race, and administrative roles in the attempt to find the most accurate gender wage gap possible using 2018 salary data. This study not only examines the gender wage gap within UNLV, but also at UNR. This study compared the two institutions in order to detect whether having a female president and provost had any effect on gender pay discrimination in comparison to having a male president and provost. We also looked at the gender composition of administrators at both universities and found that a majority of these administrative roles are given to men- giving them a large boost in salary. Transparent Nevada salary data from 2018 was utilized to run regressions for both institutions. The regression analysis results showed a marginally significant gender wage gap for UNLV and a statistically significant gap for UNR. While the gender wage gap at UNLV showed smaller numbers compared to UNR, the presence of overlapping confidence intervals makes it invalid that UNLV has a smaller gender pay gap in comparison to UNR. In assessing gender wage gaps and the connection to female representation, future researchers should increase sample size and review salary data from more than one year.

A Timeline of Oculocutaneous Albinism
Mohammed Abushanab, Maria Ceroni, and Kimberly Morán
The purpose of this research timeline is to synthesize the natural history of Oculocutaneous Albinism (OCA), discover gaps in knowledge, as well as understand the genes and mutations that incite the disease. It is through methods of literature-based research that we found the earliest recognition of OCA and investigated it up to its most current state of research. The rate of research remains steady and continuous with the focus varying widely; either by examining more of the genes involved in the disease or by taking more in-depth looks at mutational analyses of genes that are already observed to be linked to the disease. OCA is a group of autosomal recessive disorders characterized by decreased or absent pigmentation in the hair, skin, and eyes. The genotypes and phenotypes of OCA vary in the population and are broken down into a clinical spectrum which consists of OCA1A, being the most severe, in addition to the milder forms which consist of OCA1B, OCA2, OCA3, and OCA4, which show mild pigment accumulation over time. The majority of these forms are caused by mutations in the TYR gene, which is responsible for the production of melanin, as well as the OCA2 gene, which is responsible for the transport of melanin within a melanocyte. The significance of this research timeline is to look at the natural history of OCA in hopes to understand the mechanism of the disease and look at the current research status of the disease.
The Office of Undergraduate Research (OUR) provides students with the opportunity to present their research at three annual undergraduate research symposia. This collection contains student posters.
