A Two-Hit Model Of Executive Dysfunction: Simulated Galactic Cosmic Radiation Primes Latent Deficits Revealed By Sleep Fragmentation, Richard A. Britten, Ella N. Tamgue, Paola Arriaga Alvarado, Arriyam S. Fesshaye, Larry D. Sanford

Department Radiation Oncology & Biophysics Faculty Publications

Future Artemis-class missions to Mars will expose astronauts to prolonged space radiation (SR), sleep disruption, and operational demands requiring greater autonomy, placing decision making and executive function at heightened risk. Both SR and sleep fragmentation (SF) independently impair cognition, yet their combined effects remain poorly understood. Using the Associative Recognition Memory and Interference (ARMIT) task, we assessed cognitive performance in male rats exposed to 10 cGy of Galactic Cosmic Ray simulation (GCRsim), SF, or both. Under well-rested conditions, GCRsim-exposed rats exhibited overt deficits in the C.1.2 stage, performing at chance when reinforcement contingencies shifted, consistent with impaired cognitive flexibility. In …

Cluster Conversation: (Re)Writing Our Histories, (Re)Building Feminist Worlds: Working Toward Hope In The Archives, Ruth Osorio, Lamaya Williams, Megan Mcintyre

English Faculty Publications

[Introduction] "Hope is not like a lottery ticket you can sit on the sofa and clutch, feeling lucky. [...] Hope is an ax you break down doors with in an emergency." - Rebecca Solnit

In 2018, Cheryl Glenn wrote, "The work of feminist rhetorical historiography is far from done; in fact, it has just begun-and it is anchored in hope." Following Glenn, we explore hope in this cluster as a methodological imperative in the archives. Informed by theorists Paulo Freire, bell hooks, Rebecca Solnit, and Cornel West, the writers in this Cluster Conversation envision hope as a radical orientation toward …

Threats To Democracy: A Danger To Social Justice For All, José Luis Irizarry, Rajade M. Berry-James, Duchess D. Humphrey, Rachel Emas, Bruce D. Mcdonald Iii, James Nordin, Michael Lee, Lindsey L. Evans, Anthony M. Starke Jr., Jay M. Grosflam

School of Public Service Faculty Publications

This essay argues that threats to democracy—both global and domestic—pose an existential risk to the advancement of social justice. It explores how democratic backsliding undermines efforts to achieve social justice for all, examining anti-democratic practices such as misinformation, voter suppression, institutional dismantling, and the politicization of public service. Highlighting the interdependence between democratic institutions and social equity in public governance, the authors propose a multilevel response framework to foster democratic resilience through civic engagement, institutional accountability, and collective action. In this essay, members of the Board of the Section on Democracy and Social Justice (DSJ) of the American Society for …

Atmospheric Chemistry Experiment (Ace) Winds, Matthew Wyatt, Peter F. Bernath, Chris Boone, Léo Lavy, Ryan Johnson

Chemistry & Biochemistry Faculty Publications

The Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) uses limb geometry to measure transmittance spectra of Earth's atmosphere by solar occultation. Line-of-sight wind speeds can be derived via Doppler shifts of molecular lines in infrared spectra. The wind look direction angles relative to geodetic North are derived from geometry. We validate the new ACE version 5.3 (v.5.3) line-of-sight winds with MIGHTI and meteor radar vector wind observations and find a ±15 m/s sunrise/sunset shift above 80 km. We also compare line-of-sight winds from ACE-FTS v.5.2 and v.5.3 with vector winds from the MERRA-2, HWM14, and WACCM-X models. A ±15 m/s …

The Lived Experiences Of Fathers With Transgender Children Under 18 In States Banning Gender-Affirming Care, Ashley Perez

Dissertations and Theses

Parents of transgender individuals can experience numerous stressors in accessing overall care and support for their child's health and well-being. Parents can also undergo significant personal growth and change because their child is transgender. Unfortunately, the majority of the current literature focuses on mothers' experiences with transgender children. This study advances knowledge that can further support families navigating life with a transgender child, as the lived experiences of fathers are greatly lacking. Furthermore, the political and environmental scope in which the family is located can impact what families face when accessing care and support for their child and can result …

Childhood Betrayal Trauma And Suicidal Ideation: The Role Of Early Maladaptive Schemas And Interpersonal Problems, Christine Yost

Dissertations and Theses

Betrayal trauma (Freyd, 1996) is a specific form of trauma that occurs when a child is significantly harmed by someone they depend on or trust. Prior research has demonstrated that betrayal trauma is more strongly associated with adverse mental health outcomes than traumas lower in interpersonal betrayal, yet few studies have examined its relationship with suicidal ideation or identified mechanisms that explain this association. The present study tested a path model in a sample of 391 young adults aged 18-34 who endorsed suicidal ideation in the past year. The model examined whether specific early maladaptive schemas (emotional deprivation, social isolation/alienation, …

Emergent Leadership: A Study Of Ethiopian And Eritrean Diaspora Leaders, Bethel Zelalem

Theses and Dissertations

This study explores the lived experiences of young Ethiopian and Eritrean diaspora leaders in the United States who have been recognized by others as embodying emergent leadership. The research was inspired by the firsthand observations of a gap in leadership representation and recognition among first- and second-generation East African diaspora young adults, particularly those navigating bicultural identities and intergenerational tension. Guided by Borderland Theory (Anzaldúa, 1987) and Emergent Leadership Theory (Bormann, 1972; Mumford et al., 2002), the study explored how young adult Ethiopian and Eritrean diaspora members in the United States, nominated as embodying emergent leadership by their communities, experience …

Cleansing Our Recycling Failures: How Guilt And Outrage Lead To Different Types Of Pro-Environmental Behavior, Cody D. Packard

CGU Theses & Dissertations

Most Americans view recycling as “the right thing to do,” yet U.S. recycling rates lag behind other developed countries, and Americans are quick to justify why they do not recycle more (e.g., laziness, inconvenience). Recent messaging has highlighted recycling failures in the U.S., but how effective are these messages, and do they create individual behavioral changes? According to research on moral self-regulation, failing to act morally can threaten a person’s moral self-concept, eliciting moral emotions (i.e., guilt and outrage), and motivating compensatory behavior (such as increased recycling). Three studies examined whether watching a video about poor recycling in the U.S. …

Humans Among Giants: Urban Vitality And Implications Of Vertical Development In Hong Kong, Laura Jaramillo

Pomona Senior Theses

This thesis explores the complex relationship between vertical urbanism and street life, using Hong Kong as a case study to investigate how human-scale urbanism persists and adapts amidst the dominance of skyscrapers. While vertical structures symbolize modernity, economic growth, and global influence, they often overshadow the vibrancy and social connectivity that characterize ground-level spaces. This research draws on the theoretical frameworks of Jane Jacobs, David Harvey, and David Sibley to examine the interplay between vertical urbanism and street life, focusing on how spatial design impacts community engagement and cultural vibrancy. By analyzing the coexistence of modern skyscrapers and traditional street-level …

The New Urbanism In New York City: A Case Study Comparing Battery Park City And Alphabet City, Lena Farley

Pomona Senior Theses

This thesis examines two Manhattan neighborhoods, Battery Park City and Alphabet City, through the lens of New Urbanism—an urban planning approach developed in the 1990s. New Urbanist principles prioritize walkability, connectivity, mixed-use development, diversity, varied housing options, architectural quality, green transportation, sustainability, and accessible green spaces. While Battery Park City represents a top-down, master-planned New Urbanist neighborhood based on a 1979 plan, Alphabet City emerged from the 1811 Manhattan grid with significant community-driven design, notably through community gardens and grassroots initiatives. Using a mixed-methods approach including residential surveys, qualitative, and quantitative analyses, this research investigates how these neighborhoods embody New …

Huchum: The Legacy Of Fire Suppression, Indigenous Land Management, And Media Representation, Carolyn Coyne

Pomona Senior Theses

In my thesis, I examine how various forms of news media from the 1900s to present day in Ohlone territory have framed a particular hegemonic ideology around fire that matches early colonial journal entries – an ideology that is fueled by fear, sensationalism, and exclusion and directly commits violence against the Ohlone people. I investigate this time period because this is when modern news corporations, like The New York Times, rose into prominence. Specifically, I question how media representations of fire inform regulations over controlled burns; what are the similarities in discourse between media framing and policy? What tactics are …

Rwanda's Natural Remedies: A Fresh Look At The Fight Against Malaria, Leandre Nsabimana Ndisanze

Pomona Senior Theses

Malaria remains one of the most devastating parasitic diseases globally, disproportionately affecting sub-Saharan Africa, where Rwanda continues to face high transmission rates and rising resistance to conventional interventions. Despite decades of control efforts, the emergence of drug-resistant Plasmodium falciparum and insecticide-resistant Anopheles mosquitoes threatens to reverse recent gains. This research responds to the urgent need for sustainable and culturally relevant alternatives by exploring the therapeutic potential of Rwandan traditional medicinal plants. These indigenous remedies, long used by local healers, offer an underexplored reservoir of bioactive compounds that may provide the basis for novel antimalarial drugs.

The central hypothesis of this …

Shall I: Do The Motivations For Breakup Sex Differ Across Different Scenarios?, T. Joel Wade, Zoe Macuto

Faculty Journal Articles

This research investigated endorsement of the 4 motivators (relationship maintenance, ambivalence, hedonism, miscellaneous) for engaging in breakup sex across three relationship breakup scenarios, i.e., a breakup occurred due to: general reasons, infidelity, and being in a long distance relationship using an online questionnaire with a primarily White, primarily heterosexual sample (n = 304, Mage = 20.67). Results indicated that women are more likely than men to engage in breakup sex for relationship maintenance reasons when the breakup is due to general reasons, and for a long distance breakup scenario, non-heterosexuals engage in breakup sex for relationship maintenance reasons, and overall …

The Influence Of Familial Nudging On Attitudes Toward Climate Change And Monetary Contributions: An Exploration Of Ease And Difficulty With Evidence From Japan, Canada, The Usa, And Norway, Hidenori Komatsu, Hiromi Kubota, Kenji Asano Asano, Yu Naga, Catherine Salmon, David Widman, Elisabeth Oberzaucher, T. Joel Wade, Leif Edward Ottesen Kennair, Maryanne L. Fisher, Rebecca Burch, Ryoko Takikawa, Samara Rice

Faculty Journal Articles

Climate change countermeasures require monetary investment for implementation through regulations, often in the form of public taxes. Therefore, public opinion on climate change is an important factor in achieving carbon neutrality (CN). How public perception is formed, leading to motivation to fund measures for CN, needs to be identified. This study aimed to identify the causal structures of attitude change leading to financial investment through two surveys in multiple countries using nudging messages emphasizing familial support (familial nudging), which is effective in promoting pro-environmental attitudes. Study 1 (2023) examined how familial nudging moderates risk-averse attitudes toward climate change. Despite successful …

The Power To Commission: Exploring The Evaluation Capacity And The Transformative Role Of Evaluation Commissioners In The International Development Sector, Ann Marie Castleman

CGU Theses & Dissertations

Evaluation commissioners play a central role in evaluation practice by generating demand for evaluation through issuing calls for evaluation services and managing evaluation contracts (Lemire, Nielsen et al., 2018; Nielsen et al., 2018b), particularly in the international development sector. Yet few competency sets specify the knowledge and skills needed to conduct this work. Even less is known about the evaluation marketplace in the international development sector and the contract mechanisms used to procure evaluation services.

This research explored the capacity to commission evaluation among international nongovernmental organization (INGO) evaluation commissioners, including individual competencies and practices for commissioning an evaluation, factors …

Declarative Design For Spatial Analysis Models, Yassine Elouri

CGU Theses & Dissertations

Geographic Information Systems (GIS) have become indispensable tools in addressing complex spatial challenges across diverse domains, including urban planning, environmental conservation, and climate change. However, the technical expertise required to use GIS effectively, particularly proficiency in general-purpose programming languages (GPLs), remains a significant barrier to broader adoption. Domain-Specific Languages (DSLs) have proven to lower this barrier by offering tailored abstractions that simplify problem-solving in specific domains. Despite their potential, the GIS domain lacks a formal DSL framework that bridges the gap between the design of spatial analysis models and their practical implementation. This research addresses this gap by proposing Gaia, …

Market Implied Risk-Free Rates: An Analysis Of The Put-Call Parity Implied Rate, Silviu Velovici

CGU Theses & Dissertations

This study investigates the interest rate implied by put-call parity as an alternative, market-based proxy for the risk-free rate. Studying the implied risk-free rate from option prices is important because it provides insights into how market participants collectively perceive short-term financing conditions, independent of official Treasury-Bill yields. Since Treasury securities and the LIBOR are conventionally used as proxies for the risk-free rate, any persistent discrepancy between the put-call parity implied rate and the Treasury-Bill rate, or the put-call parity implied spread, can be interpreted as a signal of market frictions, investor behavior anomalies, sentiment-driven pricing dynamics, or information asymmetries.

Traditional And Non-Traditional Behavioral Tests Demonstrate The Attenuation Of Cognitive Deficits By Therapeutic Hypothermia In A Rat Model Of Neonatal Hypoxic-Ischemic Encephalopathy, Angela Saadat, Cortney Kaszowski, Haree Pallera, Frank Lattanzio, Richard A. Britten, Asna Sulaiman, Stephanie Newman, Alireza Hosseini, Tushar Shah

Department of Pediatrics Faculty Publications

Introduction: Neonatal hypoxic-ischemic encephalopathy (HIE) is neurological disease caused by the deprivation of oxygen and blood flow to the brain during the developmentally-critical perinatal period. Therapeutic hypothermia (TH) is the standard of care treatment for HIE, though cognitive deficits can persistent throughout life despite treatment. The nature of these deficits, and the impacts of TH and sex are not well understood, and this presents a key barrier in the development of novel therapeutics.

Methods: The goal of this study was to enhance the characterization and measurement of cognitive outcomes with tasks that measure spontaneous behaviors in a rodent models of …

A Bibliometric Analysis Of Ai-Driven Healthcare Literature Containing Kos Keywords: Trends, Themes, And Gaps, Julaine Clunis, Eric Asare

STEMPS Faculty Publications

As artificial intelligence (AI) becomes increasingly embedded in healthcare applications, concerns have emerged around the trustworthiness, interpretability, and context-awareness of these systems. Knowledge Organization Systems (KOS) hold considerable potential to address these challenges by supporting semantic standardization, explainability, and domain alignment. This study presents a bibliometric analysis of scholarly publications referencing both AI and healthcare concepts to examine how KOS are positioned within this evolving discourse. The findings indicate that while early literature frequently and explicitly referenced KOS—such as ontologies, controlled vocabularies, and classification systems—their visibility has declined relative to newer paradigms such as machine learning and large language models. …

Department of Pediatrics Faculty Publications

Purpose

Identifying tobacco products use (TPU) patterns among cancer survivors (CSs) is critical to optimize survivorship care. This study examines exclusive cigarette/e-cigarette, dual (two tobacco-products) and poly (≥ 3 tobacco-products) use among CSs (vs. no cancer history) and its sub-types: smoking-related-cancers (SRCs) vs. non-smoking-related cancers (NSRCs) while also exploring socio-demographic factors.

Methods

The study analyzed 86,551 adults from the 2021–2023 National Health Interview Survey, including 10,846 (9.7%) CSs. Participants were categorized and analyzed based on their CSs status and TPU patterns. Weighted logistic regression models assessed the relationship between TPU and CSs status while adjusting for socio-demographic characteristics.

Results

Optimal decision-making requires consideration of internal and external contexts. Biased decision-making is a transdiagnostic symptom of neuropsychiatric disorders. We created a computational model demonstrating how the striosome compartment of the striatum constructs a context-dependent mathematical space for decision-making computations, and how the matrix compartment uses this space to define action value. The model explains multiple experimental results and unifies other theories like reward prediction error, roles of the direct versus indirect pathways, and roles of the striosome versus matrix, under one framework. We also found, through new analyses, that striosome and matrix neurons increase their synchrony during difficult tasks, caused …
