Analyzing Conformational Changes In The Binding Of Hiv-1 Matrix Protein, N And C Terminals, To Calmodulin, Nousha Karimi, Fabian Valdez, Davis Mau, K. Sakamaki

Student Scholar Symposium Abstracts and Posters

Worldwide, more than 38 million people are living with human immunodeficiency virus (HIV), about 84 million people have become infected with HIV since the start of the epidemic, and 40.1 million of those diagnoses led to death. HIV Type-1 is the most common type of HIV, attacking the body’s immune system by destroying CD4 cells. The virus attaches itself to the CD4 cell, taking control of its DNA and replicating itself to release more HIV into the bloodstream. The Gag proteins of HIV-1 are crucial players in the virus’ assembly, release, and maturation; it utilizes its essential matrix protein (MA) …

Reconnecting With Exes And Having Sex With Platonic Roommates During The First Five Months Of The Covid - 19 Pandemic, Valentyna Simon, Alex Kraft, Amanda Gesselman, Justin Garcia

Student Scholar Symposium Abstracts and Posters

The first few months of the COVID-19 pandemic limited people’s interactions as a result of social distancing and stay-at-home orders across the U.S., and research documented declines in partnered sex during this time (Hensel et al., 2020). It is unclear if people who were single during the first few months of the pandemic found sexual connections with ex-partners or roommates. In the present study, we examined the prevalence of people contacting ex-partners and non-romantic roommates to engage in sex.

We analyzed data from a national sample of people who were currently single in the U.S. as part of The Kinsey …

Analysis Of Speech-To-Text Algorithms In Recognizing Down Syndrome Conversations, Kayla Anderson, Cecilia Marie Abrahamsson, Yingying 'Yuki' Chen, Franceli L. Cibrian

Student Scholar Symposium Abstracts and Posters

Introduction: Speech-to-text technology has become key in supporting technologies such as voice assistants (e.g., Alexa, Siri). Unfortunately, some individuals with speech differences, such as accents, female voices, children, or individuals with disabilities such as Down Syndrome, are not well recognized, creating issues in inclusivity. The first step toward making it more inclusive is to figure out where the errors or weaknesses are in speech-to-text algorithms (YouTube, IBM, Zoom, and Azure) in recognizing dialogs from diverse populations.

Methods: We analyze 10 videos from the ‘Special Books by Special Kids’ YouTube channel. Videos include 15 people with Down Syndrome and 6 Neurotypicals. …

How Demographics Influence Self-Image, Leyla Rakshani, Melissa Brillhart, Stephanie Yu, Aaron Schurger

Student Scholar Symposium Abstracts and Posters

When creating psychological research surveys, demographics are typically recorded at the end of the main survey. The reasoning behind psychologists placing demographic questions at the end can be to omit any biases from the participants (Hughes et al., 2016). However, does the placement of these types of questions influence people without them knowing? This research project will answer these questions to find the effects of demographic question placement on participants. Specifically, can demographic question placement prime individuals and their self-rating of attractiveness and the overall impact of demographic placement on survey results? To test this question, this project will conduct …

Formula 101 Using 2022 Formula One Season Data To Understand The Race Results, Christopher Garcia, Oliver Lopez

Student Scholar Symposium Abstracts and Posters

The reason why I am interested in Formula One is that my friend showed me what Formula One was all about. It became interesting to see the action of the sport, including the battles the drivers have during the race and how fast they go through a corner. Also, when qualifying comes around, they push their car to the absolute limit to gain a few seconds off their opponents. The drivers only in the top 10 receive points from the winner getting 25 points, the last driver in the top 10 getting 1 point, and those below the top ten …

Central Modulation Of Postural Control In Response To Task Demands And Fatigue In Individuals With And Without A History Of Low Back Pain, Jolene Kay Soliman, Jo Armour Smith

Student Scholar Symposium Abstracts and Posters

Background During voluntary limb movement, feedforward postural activation of the trunk and hip musculature occurs to maintain postural stability. This is called an anticipatory postural adjustment (APA). Onset of trunk muscle APAs is delayed in symptomatic individuals with persistent low back pain (LBP). It is not clear how spatial APA organization is affected, or if adaptations in APAs persist between symptomatic episodes. We used two versions of a supine active leg raise task to examine central modulation of APAs. One version of the task, the supported leg raise (SLR) does not elicit trunk/hip APAs. The other, the unsupported leg raise …

Mindfulness Meditation As A Complementary Therapy For Chronic Migraines, Isaac Min, Manjari Murali

Student Scholar Symposium Abstracts and Posters

Migraine headaches, the most common neurological disease across all age groups, affect over one billion individuals worldwide, with symptoms ranging from moderate to severe. Migraines differ in intensity and are accompanied by secondary symptoms, such as neck pain, nausea, and vomiting. Current efforts in treating migraines focus on preventative drug therapy to reduce the frequency of migraine attacks. Although mindfulness-based approaches such as MBSR may serve as an alternative method of reducing the severity of migraine attacks, studies investigating the efficacy of MBSR are limited.

A meta-analysis provides insights into the pathogenesis of migraines through the identification of three genes …

The Effects Of Media Usage On Climate Change Beliefs, Leia Hernandez

Student Scholar Symposium Abstracts and Posters

The subject of climate change has been a controversial debate for the past decade on whether it is real or just a myth. In this paper, the research that is found from various surveys will examine the correlation between fear of climate change and types of media usage. The correlation between fear of climate change and a person’s media usage will also demonstrate how media usage affects and shapes public opinion. The data associated with the fear of climate change was collected through the Chapman University American Fear Survey (CSAF). The survey sample was conducted on 1035 participants which is …

Engagement In Diverse Sexual Behaviors And Desire For Different Types Of Relationships Among Single Heterosexual People When Covid-19 Vaccines Were First Available, Manya Dhupar, Emily Foster, Amanda Gesselman, Justin Garcia

Student Scholar Symposium Abstracts and Posters

Background Decades of research have found a consistent gender difference in sexuality: men tend to desire short-term and casual relationships, and women desire monogamous relationships (Petersen & Hyde, 2010; Moors et al., 2013). The COVID-19 pandemic provides a context that may shift a person’s desires for sexual activities or types of relationships. Recent research suggests that the pandemic allowed people to reevaluate their intimate lives, including lowered interest in monogamy and increased exploration of sexual activities (Lehmiller et al., 2021; Masterson et al., under review). Method: In the present study, we analyzed data from a national sample of single …

Climate Change Skepticism: Who And Why?, Mia Huyen Truong

Student Scholar Symposium Abstracts and Posters

Despite persistent scientific consensus urging immediate action, political polarization, and skepticism have hindered effective climate change mitigation, especially in the United States. This paper explores the factors influencing climate change attitudes among different groups, focusing on right-wing affiliates and Christian believers. Drawing on the Anti-Reflexivity Thesis (McCright and Dunlap, 2001-2010) and Information Processing Theory (Wood & Vedlitz, 2007), we investigate the effects of individual characteristics, including partisan ideology, party identification, educational attainment, and Christian faith. Using Wave 7 (2021) of the Chapman Survey of American Fears Survey, a nationwide sample of different fears among U.S. adults, this study aims to …

Catalysts are important in manufacturing processes, as they make them more efficient and useful. To develop better catalysts, we need to know how they work by studying how methanol breaks down on platinum. TPD and TD-SFG spectroscopy are used to study by providing the vibrational spectra of methanol on the platinum surface as temperature changes.

The Effects Of Trauma On Holocaust Survivors After The War, Natalie Braker

Student Scholar Symposium Abstracts and Posters

This paper will examine the effects of trauma among Holocaust survivors after the war, including Post-Traumatic Stress Syndrome (PTSD), triggers, nightmares, and anxiety. It will review clinical research by comparing it to the range of experiences of Holocaust survivors as described in videotaped interviews during the late 1980s and early 1990s. Upon reviewing existing literature, it becomes clear that PTSD is life-long for Holocaust survivors. PTSD is a mental health condition triggered by either experiencing or witnessing a terrifying event or a series of events. There are four general types of PTSD symptoms: intrusive memories, avoidance, negative changes in thinking …

Sexual Dimorphism In Bidirectional Sr-Mitochondria Crosstalk In Ventricular Cardiomyocytes, Richard T Clements, Radmila Terentyeva, Shanna Hamilton, Paul M L Janssen, Karim Roder, Benjamin Y Martin, Fruzsina Perger, Timothy G Schneider, Zuzana Nichtova, Anindhya S Das, Roland Veress, Beth S Lee, Do-Gyoon Kim, Gideon Koren, Matthew S Stratton, György Csordás, Federica Accornero, Andriy E Belevych, Sandor Gyorke, Dmitry Terentyev

Calcium transfer into the mitochondrial matrix during sarcoplasmic reticulum (SR) Ca²⁺ release is essential to boost energy production in ventricular cardiomyocytes (VCMs) and match increased metabolic demand. Mitochondria from female hearts exhibit lower mito-[Ca²⁺] and produce less reactive oxygen species (ROS) compared to males, without change in respiration capacity. We hypothesized that in female VCMs, more efficient electron transport chain (ETC) organization into supercomplexes offsets the deficit in mito-Ca²⁺ accumulation, thereby reducing ROS production and stress-induced intracellular Ca²⁺ mishandling. Experiments using mitochondria-targeted biosensors confirmed lower mito-ROS and mito-[Ca²⁺] in female rat VCMs challenged …

From Factory Schooling To Nai Taleem: A Paradigm Shift In Education, Manish Jain

Journal of Contemplative and Holistic Education

The article invites readers to question and reflect on the purpose of modern education and narratives of a good life, success and happiness. Modern, capitalistic, industrialized, urbanized and colonial (and colonizing) ways of living and being have created numerous global challenges. In light of these challenges, we need to re-examine our educational systems. I explore the potential of nai taleem as a philosophy of learning, living, and being; one that decolonizes education, our monoculture mindsets, and our notions of a good life. In an increasingly globalized, albeit disconnected, world I call for nai taleem as a means for building meaningful …

A Probabilistic Exploration Of Food Supplementation And Assistance, Logan Mattingly

Honors College Theses

Food insecurity is a stark threat that grips our country and affects households throughout our country. Dietary insufficiency manifests itself in ways that affect health and public safety. According to researchers, individuals who suffer from food insecurity have a higher risk of aggression, anxiety, suicide ideation and depression. These problems tend to occur unequally distributed among those households with lower income. In this work, an exploratory analysis within these data sets will be performed to examine the socio-economic, biographical, nutritional, and geographical principal components of food insecurity among survey participants and how the US Supplemental Nutrition Assistance Program (SNAP) effects …

Ultra-Trace Analysis Of Fallout Plutonium Isotopes In Soil: Emerging Trends And Future Perspectives, Sophia M. Dowell, Olivier S. Humphrey, William H. Blake, Odipo Osano, Simon Chenery, Michael J. Watts

School of Geography, Earth and Environmental Sciences

The measurement of isotopic abundances and ratio variations of plutonium can provide important information about the sources and behaviours of radiogenic isotopes in the environment. The detection of ultra-trace isotopes of plutonium is increasing interest in the scientific literature for the determination of soil erosion rates due to their long retention times in the environment. The characteristics of plutonium within the environment make it an ideal tracer for the determination of soil redistribution rates and its robustness presents the opportunity to replace more commonly used radioisotopes such as 137Cesium and 210Lead. However, ultra-trace analysis of plutonium (fg g−1) presents analytical …

Pathogenesis Of Oral Toxicities Associated With Targeted Therapy And Immunotherapy, Alessandro Villa

All Publications

Targeted therapy and immunotherapy have redefined cancer treatment. While they have enhanced tumor response and improved survival rates in many cancer types, toxicities continue to occur, and these often involve the oral cavity. Broadly reported as "mucositis" or "stomatitis," oral toxicities induced by targeted therapies differ clinically and mechanistically from those associated with conventional chemotherapy. Manifesting primarily as mucosal lesions, salivary gland hypofunction, or orofacial neuropathies, these oral toxicities may nonetheless lead to significant morbidity and impact patients' quality of life, thereby compromising clinical outcomes. We conclude that familiarity with the spectrum of associated toxicities and understanding of their pathogenesis …

Transtrauma: Conceptualizing The Lived Experiences Of Vietnamese American Youth, Khánh Lê

Journal of Southeast Asian American Education and Advancement

Drawing on empirical data from qualitative research I conducted with eight Vietnamese American youth in the Fall of 2020, this paper forwards transtrauma, a new framework for conceptualizing and understanding the lived experiences of Vietnamese American youth. The concept of transtrauma goes beyond the pathologizing of individual trauma, to examine how structures of domination inflict and extend trauma in marginalized communities, such as that of Vietnamese American communities. Transtrauma transcends the overt and linear focus on trauma as a single experience and the examination of how institutionalized violence by nation states shapes the experiences of Vietnamese Americans. This conceptualization …

Reviews Of The Shared Room And The Most Beautiful Thing, Bao Diep

Journal of Southeast Asian American Education and Advancement

Grief and Loss are often seen as taboo subjects to discuss openly in many cultures. However, grief is universal, perpetual, and complex. Grief can take many forms and depend on the nature of the attachment between the survivor and the dead (people, animals, living things). When Loss happens, the survivor’s attachment will influence the shape and level of grief. Kao Kalia Yang (2020) has brought the topic of attachment, grief and loss to her children’s books, The Shared Room and The Most Beautiful Things, to initiate this difficult conversation.

Review Of Afterparties Stories By Anthony Veasna So, Allan Zheng

Journal of Southeast Asian American Education and Advancement

You’re Khmer, right?” Tevy, one of So’s characters from “Three Women of Chuck’s Donuts,” asks a customer (So, 2021, p. 21). Khmer is commonly seen as an ethnic identity and distinct from the broader national identity of Cambodian. Therefore, what does it mean to be Khmer, or generally as I will write in this review, Cambodian American? In his short story collection Afterparties (2021), Anthony Veasna So explores this question in Afterparties (2021) through a rich collage of stories featuring sisters in a donut shop, a cynical high school literature teacher, a reluctant son at the temple to tver bon, …

Notes To My Dad, Karen Vang

Journal of Southeast Asian American Education and Advancement

This is a critical reflection of my experience navigating higher education as a Hmong woman. My dad is well known among our clan to be very “traditional” and respectable. However, over the past 6 years during my graduate studies, my dad has remained my number one supporter. I sometimes, I tell him he is the chosen one, to derail his beliefs. At times, I begin to imagine what life would be like if I were a son. As for me, one of my mentors told me one time, that it is my sacred path to do this work. I have …
