Unique Marketing Struggles in Web3 Compared to Web2
Vincent D'Ambrosia
4-28-2023Web 2 is a technical term in reference to the internet as we know it today and focuses on social media and allowing people to interact better and communicate with each other. Web3 is the next evolution of the internet and its focus leans towards decentralization which aims to place more control of an individual’s data and finances into their own hands. Due to this decentralization, connecting with people is more difficult compared to Web2 communication outlets. NFTs are a common and popular product in Web3. While they come in many forms, the collectible market dominates NFTs and these can be compared to a Pokemon card minus the cardboard. Opensea is a popular centralized marketplace that facilitates buying and selling of NFTs. Web2 brands typically market value in their product to their audience whether it be entertainment or influencer value, a successful customer may be someone who recognizes enough worth in the product to spend money. Web3 brands are typically selling you personal ownership as part of the NFT. Many collections will have a set number for sale with each one being unique and the only one like it, which helps towards the perception of scarcity.

Sensitivity to Musical Groove is Predicted by Sensitivity to Musical Chills, but not General Musicality
Nicole Datastanyan, Kaela Omengan, Isabella Aceituno aceituno@unlv.nevada.edu, Solena Mednicoff, and Sivan Barashy
4-28-2023Previous research suggests that individual differences in musicality may predict groove sensitivity. Groovy music is highly stimulating music that makes listeners want to move while eliciting feelings of pleasure and arousal. Musicality refers to listeners’ affinity to music including musical talent, sophistication, and expertise. Frisson (musical chills) is an intense emotional response to music characterized by goosebumps or a tingling sensation.

Examining Differences in PTSD Symptomatology Among Youth Who Have Experienced Sexual and Psychological Maltreatment Using Nonparametric Analyses
Emma Domschot and Vanni Jefferson V. Arcaina
4-28-2023Child sexual abuse, even when accounting for co-occuring risk factors, may be predictive of worse clinical outcomes when comparing to other types of trauma (Kisiel et al., 2014). However, contrasting research suggests that psychological maltreatment may independently contribute to a negative risk of clinical outcomes comparable to child sexual abuse (Hodgon et al., 2014). Other studies suggest that complex trauma, in terms of experiencing prolonged and several traumas over a period of time, may often lead to an increased risk of post-traumatic stress disorder (John et al., 2019). The current study aimed to examine differences in PTSD symptomatology among youth who experience sexual maltreatment, psychological maltreatment, and both concurrently.

Can Reconsolidation Account for the Misinformation Effect?
Olesya T. Frolova and Gabriel E. Hull
4-28-2023A successful replication of Rindal & Zaragoza (2016) would indicate that reconsolidation cannot account for the misinformation effect. Current preliminary data supports the results found by the original study, suggesting that an alternative theory must be explored to explain the misinformation effect. For example, it is possible that the original memory is not altered by the misinformation but competes with the original memory leading to temporary inaccessibility at test. Results from this study could influence law enforcement interview techniques to avoid false testimonies. One limitation of the study is that performance on the test was potentially too good; this will be addressed in future studies.

Perceptual Learning of Infants Across Domains
Melanie Garcia, Carolina A. Herrera, Ryan K. Perez, Rodica R. Constantine, and Erin E. Hannon
12-8-2023Infancy is a unique developmental period in which there is rapid attunement of perceptual systems to specific environmental properties. Perceptual narrowing: By the end of the first year, infants become adept processors and develop expertise of familiar socially meaningful domains such as faces, language, and music leading to subsequent social and cognitive abilities. The mechanisms driving these perceptual changes remain debated, with contrasting accounts proposing experience-dependent or domain-general influences. Objective: This research aims to investigate whether perceptual narrowing in early development is primarily driven by domain-specific experiences or by domain-general factors such as brain maturation and information processing.

Does Children’s Openness to Experience and Musicality Influence Perception of Major and Minor Musical Modes?
Bryanna Grijalva, Natalya Sayegh, Carlos Tamayo, Ryan K. Perez, Sivan Barashy, and Solena Mednicoff
4-28-2023Previous studies have found a relationship between openness to experience, musical training, and auditory abilities in adults. Openness to experience: one of the major personality traits that encapsulates how open-minded, creative, insightful, and imaginative a person can be. Tonality: the orientation of melodies and harmonies toward a referential pitch class. Musicality: one’s enthusiasm for music and desire to make music.

Listener’s Judgement of Tempo Is Influenced by Dance Speed
Carolina A. Herrera, Ryan K. Perez, Jared W. Leslie, and Erin E. Hannon
12-8-2023The tempo of a musical composition is typically denoted by the number of beats per minute (BPM). Nevertheless, perception of tempo is inherently subjective, and it can be shaped by the listener's familiarity with both musical and dance elements [1, 2, 3, 4]. Even when songs have the same BPM, the perceived speed of the songs can differ based on the specific dance form and cultural context [1, 4]

Social Media Marketing Related to Nike
Felipe Herrera
4-28-2023This research examines positive and negative attitudes about social media marketing within Nike. Understanding consumer attitudes about social media marketing is important because it affects our lives every day and we are exposed to it on a regular basis. Previous research about this product category showed that there are new tactics Nike is using to expand business, how the pandemic affected usage of social media, and the percentages of apps being used by adults in the last year. I conducted three netnography analyses by observing consumer groups on Facebook, Twitter, and Reddit social media platforms on Nike to understand consumer meanings related to this product category. I found that consumers choose to support Nike because of the risks that they take when promoting certain products or choosing to support certain individuals who may not be admired by everyone. Next, I will conduct surveys to examine consumer groups on Facebook, Twitter, and Reddit social media platforms on Nike. My research has the potential to provide insights to marketing managers in increasing traffic through certain platforms, seeing why people choose to stay loyal to certain brands, and how users interact with one another.

Sexual Abuse and Interpersonal Difficulties in Youth
Priscilla Herrera and Kinsey Ellis
4-28-2023Researchers have found childhood sexual abuse victimization to be associated with impairments in trust, social comfort, and quality of interpersonal relationships1,2,3. Research which investigates the unique relationship between sexual abuse and interpersonal difficulties among youth with a history of child maltreatment is limited. The present study aimed to investigate interpersonal functioning differences in maltreated youth who have and have not experienced sexual abuse.

Emotional Reactivity Predicts Dissociation in Maltreated Youth
Jaelin Isquith and Kinsey Ellis
4-28-2023The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) defines dissociation as “disruption in the usually integrated functions of consciousness, memory, identity or perception of the environment”11. Dissociation most commonly occurs after a traumatic experience and can take many forms; Subtypes include dissociative amnesia, absorption and imaginative involvement, passive influence, and depersonalization and derealization. Dissociation has been linked to several negative outcomes such as increased risk for development of personality disorders, suicidal ideation, and self-harm2,3. Risk factors for dissociation have been understudied in child and adolescent populations. One factor that has been found to be related to severity of dissociative symptoms and negative outcomes is emotional dysregulation4,5. The relationship between specific aspects of emotional dysregulation and dissociation is understudied. Studies which consider specific aspects of emotional reactivity in youth are particularly limited.

State Government: A Comparison of Bicameral, Biennial, Citizen Legislatures
Zachary J. Johnigan
12-8-2023Governing agencies can be classified as either federal, state, or local. The Nevada Legislature is a state level governing body that provides governance for the state of Nevada. A large part of the process of governing the state takes place during a regular legislative session, where new laws are heard then passed or denied and old laws are revised or abolished. One regular legislative session consists of 120 calendar days. In the event that not all business was able to be conducted within a regular session, the governor of the state can call for a special session to be opened. A special session is typically not budgeted and ends up costing extra money to operate. There may be operational issues surrounding current regular session lengths and frequency which attribute to the Nevada Legislature needing to open so many special sessions. This topic is of interest for the Nevada Legislature’s stakeholders. The stakeholders are the citizens of the state of Nevada who pay taxes.

Finding Diffs of Pull Request Commits
Chalinee Karawek and John Businge
12-8-2023Github is a social network that allows developers' projects to be forked for various uses, such as developing the existing repository or use the code to steer development into a new direction. As more forks are made, the more bugs that can occur due to new pull requests not synchronizing with the upstream repository. PaReco is a clone detection tool by Ramkisoen et al. (Ramkisoen et al. 2022) that identifies the changes inside the files inside a pull request by performing diff on every file. However, in this study, we take a different approach to identifying the changes inside the files of a pull request by considering a diff in the entire pull request.

Music Enhances Focus and Concentration
Daniyal Kheradmand
4-28-2023This study aimed to investigate the relationship between the genre of music listened to and its impact on enhancing focus and concentration during puzzle-solving, as measured by completion time, across a diverse sample of individuals. The researcher, Daniyal Kheradmand, conducted the study at the University of Nevada Las Vegas (UNLV) on a sample of 50 students and employees. Participants were required to solve two simple puzzles (9 pieces) while listening to their favorite music and without music. The time taken to complete each puzzle was recorded and compared. Results showed that 68% of participants completed the puzzle faster while listening to music. These findings suggest that listening to music, including one's favorite music, can improve concentration and enhance the learning process. The study emphasizes the importance of individual preferences when utilizing music as a tool to increase concentration.

Investigating the Impact of Dividing Attention on Auditory and Visual Object Memory
Sharica Lee, Julius Hernandez, and Ryan Tyler Sablan
4-28-2023Recently, we found that dividing attention reduced recollection and familiarity for visual objects, but a different pattern emerged for auditory object memory: auditory object recollection was not affected by dividing attention. This could be attributable to differing levels of baseline performance with visual memory far exceeding auditory memory. Thus, we attempted to equate baseline performance in both modalities in order to adequately investigate the previous findings.

The Time Window of Reconsolidation: A Replication
Mateo Marquez and Jessica Nguyen
4-28-2023Reconsolidation is the process whereby activating a consolidated memory can bring it into a labile state where it can be strengthened, weakened, or updated. Hupbach et al., (2007) showed that memory updating is only found when the reconsolidation process has time to complete. This finding has been argued to be due to other memory processes (Sederberg et al., 2011). Before testing alternative explanations, the result needs to be replicated by an independent lab.

Reminders of Reconsolidation: Prediction Error vs. Spatial Context
Mateo Marquez, Jessica Nguyen, and Augustine Alvarado
12-8-2023Reconsolidation is the process whereby reactivating a consolidated memory can bring it into a labile state where it can be strengthened, weakened, or updated. Spatial context and prediction error (PE) are two ways that memories can be reactivated. Spatial context refers to being in the same-environmental setting during encoding and retrieval, whereas PE refers to the mismatch between expected and observed events. Both methods have successfully reactivated consolidated memories. However, it is unclear whether reconsolidation is affected by PE when it isolated in different spaces.

Are Socio-Cultural Factors Correlated With Breastfeeding Among Latina Mothers in Nevada?
Marissa Martinez, Karen Farfan, and Luis Aceves
4-28-2023Breastfeeding has many benefits for both mother and their child (e.g., lower rates of Sudden Infant Death Syndrome, obesity, asthma, cardiovascular disease, etc.). Recent studies suggest that 93% of children born in Mexico are breastfed their child compared to 81.1% of Nevadan women reported breastfeeding their child. Previous studies suggest that socio-cultural factors such as socioeconomic status, education level, mother’s age, acculturation, cultural beliefs, and perceptions are associated with breastfeeding. Many studies have not use a validated acculturation measure.

Effects of Time-Restricted Exercise on Hypertrophy, Aerobic Adaptations, and Body Weight in Mice
Greco Neblina, Elias M. Malek, Michael B. Dial, and Austin Cooper
4-28-2023Sleep and circadian rhythms are shown to impact cellular and whole-body metabolism and exercise capacity. Mice experience adaptations (e.g., hypertrophy, increased time to exhaustion) as a result of voluntary aerobic exercise. Adaptations to aerobic exercise are influenced by the time of day at which exercise is performed due to alterations in transcriptional and translational processes that affect mitochondrial abundance. It is critical to examine the gross effects of exercise timing on metabolic adaptations and other adaptations to aerobic exercise. This knowledge can help athletes and coaches organize time-optimized training schedules and help clinicians improve patient outcomes through time-of-day related adaptations to clinical exercise regimens

Third-order Harmonic Generation in Few-Layer Graphene
Nicholas T. Pereira, Timothy Chung, and Joshua O. Island
12-8-2023Optical harmonic generation is a phenomena that occurs in nonlinear materials and can be used to study the properties of those materials. For example, the nonlinear response of layered, two-dimensional (2D) materials can be used to characterize flake thickness, lattice and stacking symmetries, and crystal strain. Here, we study third harmonic generation (THG) in graphene and few-layer graphite as a precursor to investigating nonlinear optical properties of other 2D materials. We present a custom scanning setup for optical harmonic generation and present our results on few-layer flakes. These results provide a solid basis for future measurements of other new 2D materials.
