Community–Campus Partnerships For Student Basic Needs, Jacen Greene, Lindsay Mason, Lauren Padgett, Haley Hamblin-Dold, Teresa Metzger, Michael Buttram, Shayna Lentz, Emma Chavez, Jennifer Fellabaum-Toston

National Policy Consensus Center Publications

Although much of the literature on community–university partnerships is about experiential learning (e.g., service-learning) or research (e.g., community-engaged scholarship), this article explores community–campus partnerships for supporting students’ basic needs. The need for these partnerships is vital, as the number of college students experiencing food and/or housing insecurity while obtaining their degree(s) continues to increase. Following a review of relevant literature, we share several examples of these community–campus partnerships in action. We conclude the article with a set of considerations for higher education institutions that wish to develop successful and lasting community–campus partnerships.

With advancements in detection technologies and growing interest in environmental surveillance, WBE is poised to become a standard practice in public health monitoring. Here, we provide an overview of the current state of the art of pathogen WBE, including methods of molecular detection, analysis of wastewater data, real-world applications and programs, public health interventions, and benefits and …

Contested Air: Politics, Prejudice, And Radio Broadcasting In New York State, 1925-1928, Sebastian Garcia

Graduate Studies Theses and Dissertations 2026

This thesis examines the intersection between radio broadcasting as the "new media" of the 1920s and American political culture of the period, using New York Governor and 1928 Democratic presidential candidate Alfred E. Smith as a case study. Smith entered 1925 as a political lone wolf and left the year as a triumphant victor set to take the presidency. Building on the work of Smithian scholars, this thesis illuminates how Smith’s radio use remained central to this political transformation. Smith found in radio an apt space to bypass Republican opposition and mobilize the body politic through direct engagement, which, in …

Governing Harm: Three Essays On Anti-Lgbtq+ Legislation In The United States, Kathryn Hickey

Graduate Studies Theses and Dissertations 2026

In the United States, over 140 state bills were passed between 2014 and 2024 that directly targeted the lives of LGBTQ+ individuals. Drawing on administrative evil and the minority stress model, this dissertation demonstrates how policy environments that normalize discrimination through the passage of anti-LGBTQ+ legislation can lead to devastating consequences. Using a three-essay format, the first study conducts a qualitative content analysis of state level anti-LGBTQ+ laws passed between 2015 and 2024 to identify how administrative evil is woven into the language of the legislation. The results of this analysis show these laws systematically dehumanize LGBTQ+ individuals, restrict their …

Genomic And Structural Analysis Of Major Antigenic Proteins’ Variability In The Human Relapsing Fever Spirochete Borrelia Persica, Ofir Segev, Asaf Levy, Job E Lopez, Gad Baneth

Faculty, Staff and Students Publications

Antigenic variation enables immune evasion of pathogens, yet the mechanisms for the rapid change in their antigens without loss of structural and functional features are not fully known. Tick-borne relapsing fever (TBRF) spirochetes of the genus Borrelia can be used as a model because their variable major proteins (Vmps) drive antigenic variation followed by recurrent waves of bacteremia. In this study we generated the genome of Borrelia persica LMU-C01 and evaluated Vmp structure across relapsing fever Borrelia species. Borrelia persica was found to have a genome of 1.7Mb with one linear chromosome, 12 linear and one circular plasmids. Telomeric hairpin …

Framing Home: Extending Beyond The Threshold, Kaitlin R. Kirsch

Graduate Studies Theses and Dissertations 2026

This thesis body of work inspects the changes in the artist’s relationship to domesticity and their perceived sense of control over the spaces they have called home. By creating and embellishing spaces that subvert the threshold between the physical and psychic, the works stimulate feelings of comfort or discomfort. Installations of found materials, mixed media, and text-based dark humor, come together to account for this artist’s attempt to navigate the tediousness of daily life. The work takes into consideration the intangible rules that infiltrate a household, defining the framework in which a person learns to live within, or adapt to, …

Odd Colorings Of Graphs With Maximum Degree And Surface Conditions, Matthew Kyle

Graduate Studies Theses and Dissertations 2026

A proper vertex coloring of a graph is said to be odd if, for each vertex, there is a color that is present an odd number of times in its neighborhood. Introduced as a softening of other coloring problems, this problem has recently seen much research interest. It has been conjectured that all planar graphs are odd-5-colorable. Further research has suggested bounds for odd coloring numbers of graphs with different maximum degree conditions, different girths, and on different surfaces; we progress results in all of these areas. We improve an upper bound for odd coloring numbers of graphs of maximum …

Numerical Simulation Of Micro-Cutting Processes For The Estimation Of Material Fracture Toughness, Juan J. Lainez

Graduate Studies Theses and Dissertations 2026

Accurate determination of plane-strain fracture toughness is essential for structural integrity assessments of engineering components, yet conventional ASTM standardized testing methods require large, notched specimens that are impractical in many industrial and research contexts. This thesis presents a finite element method-based approach for estimating the mode I plane-strain fracture toughness of engineering materials from orthogonal micro-cutting simulations if the continuum damage mechanics-based fracture locus is calibrated. This method will eliminate the need for pre-cracked specimens while maintaining physically grounded fracture mechanics principles. The methodology applies to the Atkins energy-based cutting force model, in which the depth-independent intercept of the specific …

Viral Dynamics Across Managed And Wild Pollinators: Integrating Immunity, Ecology, And Community Structure, Allison Malay

Graduate Studies Theses and Dissertations 2026

Managed honey bees (Apis mellifera) are critical agricultural pollinators, yet colonies continue to experience persistently high losses across North America and Europe. These declines are driven by interacting stressors, including parasites, pathogens, nutrition, and landscape context. Viral pathogens are key contributors to colony morbidity and mortality, but the processes governing variation in viral prevalence, load, and host response remain incompletely understood. This dissertation investigates how viral dynamics in honey bees emerge from interactions among host immunity, colony condition, environmental context, and pollinator community structure. By integrating measures of viral prevalence, viral load, and immune gene expression across multiple …

Exploring The Temporal Dynamics Of Gaming-The-System And Self-Regulated Learning Behaviors Within A Game-Based Learning Environment, Cameron E. Marano

Graduate Studies Theses and Dissertations 2026

Consistently monitoring and regulating cognitive and metacognitive skills during learning is difficult. As a result, game-based learning environments (GBLEs) have been designed to provide richer learning experiences. They foster self-regulated learning (SRL) skills and offer a way to study learners' interactions within complex environments. Although SRL in GBLEs has been widely studied, large gaps remain. For example, it is unclear how improper or maladaptive regulation in GBLEs signals gaming-the-system, in which learners manipulate features to avoid authentic learning. This phenomenon is widely studied in intelligent tutoring systems (ITSs). Limited research has examined how and when both gaming-the-system and SRL behaviors …

Characterization And Experimental Study Of Ammonia-Hydrogen Flames Inside A Toroidal Jet-Stirred Reactor At Atmospheric Conditions, Oli Marquez Valenzuela

Graduate Studies Theses and Dissertations 2026

Due to rising concerns about global surface temperatures and carbon emissions, there has been an increased interest in studying alternative fuels. Ammonia and hydrogen are fuels with the potential to replace general biofuels, hydrocarbons, and sustainable aviation fuels, as they do not contain any carbon, eliminating carbon emissions. However, they are both difficult to work with. Hydrogen has great combustion characteristics such as low ignition energy, high flame speed and lower heating value. However, it is volatile and difficult to store, requiring it to be compressed to high pressure or cooled to incredibly low temperatures. Ammonia can be used as …

The Role Of Adolescent Attachment In The Relationship Between Trauma And Identity, Ellie Mitova

Graduate Studies Theses and Dissertations 2026

Traumatic experiences have been shown to influence identity development during emerging adulthood, a complex developmental period. However, research examining how trauma interacts with adolescent attachment qualities to shape identity processes remains limited. Previous studies have primarily focused on infant attachment styles and their long-term developmental outcomes, leaving a gap in understanding how attachment qualities developed through relationships with parents and peers during adolescence may influence identity development in emerging adults. Additionally, while traumatic experiences have been associated with maladaptive identity processes such as rumination and identity distress, some research suggests that trauma may also contribute to deeper identity exploration and …

The Intersection Of Abuse, Child Welfare, And The Law For Intimate Partner Violence Survivors: Gender Violence As An Antagonistic Social Force, Julio Montanez

Graduate Studies Theses and Dissertations 2026

Intimate partner violence (IPV)—as gender violence—pits children’s civil rights and women’s civil liberties against each other. To explore this phenomenon, the current work features five (5) studies that aim to understand the systemic consequences of IPV and child maltreatment for victims and survivors of both types of abuse.

• Study 1 is a qualitative-deductive study featuring a directed content analysis of news media pertaining to a trial court case on lethal child maltreatment and IPV.
• Study 2 is a qualitative-inductive study featuring a feminist critical discourse analysis of trial court data on lethal child maltreatment and IPV.
• Study 3 is a …

Shock Tube Speciation Analysis Of Hydrocarbon Mixtures Relevant To Solid Fuel Combustion, Diego N. Ruiz Pena

Graduate Studies Theses and Dissertations 2026

Solid Fuel Ramjets (SFRJs) are often used in tactical applications due to their simplicity, robustness, and reliability. No moving parts, atmospheric oxidizer usage, and scalable fuel grain designs make them a great solution for compact, high-speed air-breathing propulsion systems. SFRJs operate by compressing incoming air through a fixed geometry inlet and directing it over a regressing solid fuel surface, where pyrolysis gases are released and transported downstream to the combustion chamber where thrust is generated. Hydroxyl-terminated polybutadiene (HTPB) is a commonly used fuel binder in SFRJ systems due to its high energy density, stable combustion behavior, and ease of processing. …

Molecular Heterogeneity Of Hpv-Associated Cancers And Strategies To Overcome Treatment Resistance, Danyal Daneshdoust, Anam Khan, Rani Mahyoob, Chongwen Cao, Zihao Yu, Nagireddy Putluri, Gennady Shvets, Haichang Li, Bo Zhao, Xuefeng Liu, Jenny Li

Faculty, Staff and Students Publications

Human papillomavirus (HPV) is a major driver of global cancer incidence, responsible for nearly all cervical cancers and a significant proportion of oropharyngeal, anal, and other anogenital cancers. Despite the availability of effective vaccines, HPV-associated cancers persist due to persistent infection, immune evasion, and the virus's ability to integrate into the host genome, contributing to molecular heterogeneity and therapeutic resistance. Here, we summarize molecular heterogeneity and the emerging combined therapeutic strategies. High-risk HPV types, notably HPV16 and HPV18, initiate carcinogenesis through persistent infection of epithelial basal cells and through the actions of the E6 and E7 oncoproteins, which disrupt the …

Source Credibility And Chatbots: How Design Factors Impact Chatbot Effectiveness, Kristen M. Schmidt

Graduate Studies Theses and Dissertations 2026

Source credibility theory states that the more credible a source appears to be, the more likely one is to believe both true and untrue information from it. In the modern day, misinformation is considered a major problem, particularly with virtual communication, meaning it is essential to study what factors influence a system’s source credibility. Virtual agents are a particularly relevant subject of study given that their source credibility can be impacted by both technological and social factors. Across three experiments, this dissertation utilized a novel chatbot interaction design to test how varying design factors would impact a chatbot’s source credibility …

Defect-Guided And Energy-Driven Unfolding With Learning-Based Strategies: From Geometries With Compact Refolding To Garments, Shah Wasif Sazzad

Graduate Studies Theses and Dissertations 2026

Unfolding and folding are related geometric and mechanical transformations fundamental to structural applications. Particularly, unfolding curved surfaces is important for deployable structures, garment pattern generation, etc. A central challenge is minimizing geometric distortion between a surface and its unfolded counterpart avoiding overlaps. As regions of lower Gaussian curvature typically produce less distortion during flattening, identifying curvature distribution becomes essential. Topological defects in a particle assembly on a surface in its minimum interaction-energy configuration indicate regions of concentrated curvature. In this work, an unfolding method is proposed that segments the surface using defects' location. Cutlines connecting the defects isolate lower curvature …

Data-Driven Seismic Site Classification Using Earthquake And Microtremor Horizontal-To-Vertical Spectral Ratios, Sanidhya Sharma

Graduate Studies Theses and Dissertations 2026

The prevailing seismic site classification parameter, the time-averaged shear-wave velocity in the upper 30 meters (V_S30), provides an incomplete representation of site conditions, neglecting deeper geology, impedance contrasts, and resonance phenomena. This thesis developed and validated a data-driven framework for seismic site classification based on the full spectral shape of Horizontal-to-Vertical Spectral Ratio (HVSR) curves combined with unsupervised machine learning, through two complementary research studies. Research 1 applied K-means clustering to earthquake-based HVSR (eHVSR) data from 3,186 ground motion stations across California and adjacent regions, identifying four physically distinct site clusters, characterized by low-frequency, very-low-frequency, high-frequency, and …

Toward Urban-Scale Liquefaction Hazard Analysis: Evaluation And Optimization Of Cpt-Based Lateral Displacement Assessment, Varun M. Singh

Graduate Studies Theses and Dissertations 2026

Liquefaction-induced lateral spreading is a major type of earthquake-induced ground failure hazard and poses a significant threat to infrastructure systems. While semi-empirical methods, such as Lateral Displacement Index (LDI), have been developed to estimate lateral spreading displacement (LSD), their efficacy for regional-scale liquefaction hazard assessment remains unknown. This study evaluates and improves the LDI method for urban-scale seismic hazard assessments using a comprehensive dataset consisting of 1,713 Cone Penetration Test (CPT) case histories from the 2011 Christchurch, New Zealand earthquake, and high-resolution topographic data. Comparing the predicted LSDs and ground-truth observations from both field investigations and remote-sensing surveys reveals that …

Code-Switching, Identity-Shifting, And Identity Distress Among Black Undergraduate Women Attending Predominantly White Institutions, Erin Smith

Graduate Studies Theses and Dissertations 2026

Code-switching (altering language or speech) and identity-shifting (modifying appearance or behavior) are adaptive strategies often used by individuals from marginalized groups to navigate environments shaped by dominant cultural norms. Although these behaviors are commonly discussed in qualitative literature, relatively few quantitative studies have examined their psychological correlates among Black undergraduate women attending predominantly White institutions (PWIs). These behaviors may function as coping strategies in response to racialized and gendered expectations, yet the psychological implications of these strategies remain understudied. The present study examined the relationships among identity distress, code-switching, identity-shifting, and gendered racial identity centrality within a diverse sample of …

For Whom The Tale’S Told: Multilevel Perspective On Narrative And Identity In Information Ecosystems, Jihye Song

Graduate Studies Theses and Dissertations 2026

In contemporary online information environments, narratives do not merely convey facts. They organize meaning, signal identity, and guide collective sensemaking. During periods of crisis and uncertainty, these processes become especially salient, as individuals and communities turn to social media to interpret unfolding events. At the same time, these environments are shaped by complex sociotechnical dynamics, including platform affordances, algorithmic amplification, elite influence, and grassroots participation. These dynamics form ecosystems in which narratives and identities are constructed, contested, and stabilized. Drawing on theory and empirical analyses of COVID-19 discourse on Twitter, this work develops and applies a multilevel framework to explain …

The Effects Of Episodic Facilitation And Immersion On Memory Formation During Learning Of An Exterior Preflight Inspection Procedure, Nathan A. Sonnenfeld

Graduate Studies Theses and Dissertations 2026

This research examined the use of episodic facilitation—instructional elements aligned with episodic memory (EM) processes—to affect learners’ memory of simulation training for an aviation procedure. Despite its assumed benefits in industry and theory, virtual reality (VR) has shown limited advantages over conventional media for training procedures, in part because prevailing frameworks emphasize semantic and procedural outcomes, leaving memory of training experiences as events underexamined. To address this gap, this work advances human factors research by examining EM as a design consideration, an outcome, and an explanatory mechanism for how simulation training experiences are remembered. Grounded in theories of EM and …

Dynamic Interactions Of The Compressible Reacting Flow With A Morphing Wall In A Supersonic Combustor, Mason R. Thornton

Graduate Studies Theses and Dissertations 2026

The influence of compressibility on supersonic reacting flows is explored by varying the area expansion ratio in a supersonic cavity combustor using a moving wall. In principle, this design allows on-the-fly adjustment of the combustor aft wall expansion ratio to accommodate variable inlet conditions and fueling rates. The variable back pressure broadens the operability envelope and ensures greater pressure rise recovery compared with a constant geometry combustor. The results demonstrate that modulating area expansion alters the combustor pressure distribution and can influence cavity flame dynamics. At sufficiently high equivalence ratios and compression levels, the back pressure induced by the moving …

Resources And Coping Strategies In Adverse Work Situations: A Person-Centered Approach, Chad Yagey

Graduate Studies Theses and Dissertations 2026

The resilience process model highlights an approach to how people mobilize their resources to cope and positively adapt in the face of adversity. Leveraging Conservation of Resources (COR) theory and the Work Home Resources Model (WHRM), I aim to uncover the extent to which resilience capacity (resources) and resilience enactment (coping) influence outcomes of resilience, offering one of the first empirical tests of the resilience process model. Specifically, COR theory posits that the more psychological resources someone has, the more successful they are in coping. I challenge this notion by examining whether specific profiles of the combination of resources available …

Making Unsafe Sequences Unexecutable: Formal Protocol Enforcement For Cyber-Physical Systems, Arthur Amorim

Graduate Studies Theses and Dissertations 2026

Cyber-physical systems execute physical actions in response to software commands, making their communication protocols a primary attack surface. A stealthy attack is a sequence of individually valid messages that violates a required ordering, driving the system into an unsafe state without malware or protocol violation. Existing defenses examine messages or physical state in isolation, not protocol level sequences, and cannot prevent them. Preventing them requires enforcement that makes unsafe sequences unexecutable at the communication boundary.

Formal methods offer a principled path to enforcement, but no tool spans specification to safe deployed hardware. Model checking automates proofs but has no certified …
