Navigating Liminality: Building Resources For And With Undocumented Students, Yaneyry Delfin Martinez

Cal Poly Humboldt theses and projects

Rooted in Community-Based Participatory Research (CBPR) and Liberation Sociology, this project outlines an institutional blueprint for the resources and support systems needed to address the lived realities of undocumented students at Cal Poly Humboldt (CPH). Conducted during the second Trump Administration amidst escalating hostility towards immigrants and attacks on DEI initiatives, this work documents both the structural conditions shaping undocumented students’ lives and the collective resistance that emerged in response. Furthermore, it examines how immigration policy, access to and restrictions on federal and state aid, geographic conditions, and on-campus barriers reproduce and maintain legal liminality within higher education. Grounded in …

Repairing Estranged Death: Care, Politics And Ecology In The Us Funeral Industry, Cecilia Catherine Rodriguez

Cal Poly Humboldt theses and projects

The industrialization of death practices in the US has separated humanity from natural cycles while centering white settler colonial norms that marginalize other cultural ways of caring for the dead. Through necropolitics, the contemporary death industry embodies capitalist values of commodification and a monopolization of care, separating death from community and its ecological cycles. Black and Indigenous feminist knowledges understand death as not a discrete event but instead as an ongoing process that shapes our relationships with both the human and more-than-human worlds. Engaging with feminist political ecologies, I extend a conversation about care and repair to contemporary death practices …

Decolonizing Restorative Justice: A Teaching Development Project, Lacy Felice Mitchell

Cal Poly Humboldt theses and projects

The coloniality of power serves as a central axis within the matrix of domination that characterizes global capitalist modernity, as Anibal Quijano famously argued. This power is rooted in particular ways of looking, seeing, and understanding social reality, anchored in Eurocentrism as an epistemological paradigm for the hegemonic discourse produced by the West against both internal and external categories of “other.” Such categories still inform the production of knowledge in educational settings. In this project, I engage in a critique of the coloniality of power to explore its implications and potential for critical pedagogical practice within the context of sociology …

Long-Term Relationships Between Tree Growth And Climate In The Trinity Alps Wilderness, Klamath Mountains, California, Usa, Emma R. Knepp

Cal Poly Humboldt theses and projects

The Trinity Alps Wilderness is a unique setting for evaluating late-Holocene climate variability because former glaciers occupied comparatively low elevations in a region influenced by both coastal and interior climate patterns. Tree-ring chronologies were developed from four conifer species—Shasta red fir (Abies magnifica var. shastensis), western white pine (Pinus monticola), Brewer’s spruce (Picea breweriana), and mountain hemlock (Tsuga mertensiana)—sampled at high elevations (1950 - 2300 m) near Emerald and Grizzly Lakes in the Trinity Alps Wilderness in northern California. The final chronologies included 12 Shasta red fir trees, 12 western white pine …

Species Boundaries Of The Rare Menzies’ Wallflower (Brassicaceae: Erysimum Menziesii), An Endemic Of The Northern California Coast, Cameron M. Jones

Cal Poly Humboldt theses and projects

Morphological similarity among geographically isolated populations can obscure deep evolutionary divergence, especially when convergent evolution under similar environmental conditions yields comparable phenotypes across independent lineages. Such cryptic diversity is likely underestimated in hotspots like the California Floristic Province (CFP), a global biodiversity hotspot, defined by its Mediterranean-like climate and encompassing most of California, southwestern Oregon, and northwest Baja California. The CFP is home to a disproportionate number of narrow endemics whose origins and evolutionary relationships remain poorly understood. Here, I investigate the evolutionary origins of Erysimum menziesii (Brassicaceae), a federally endangered California coastal dune endemic whose fragmented distribution has led …

Rethinking Belonging In First-Year Student Support: A Mixed-Methods Evaluation Of Eop/Sss Programing At Cal Poly Humboldt, Elizabeth Rose Silver

Cal Poly Humboldt theses and projects

This mixed-methods project examines the role of the Educational Opportunity Program and Student Support Services (EOP/SSS) first-year orientation programs, particularly STEM Summer Bridge, in supporting feelings of belonging and persistence. While institutional efforts often frame student success through metrics such as retention and concepts like sense of belonging, this project interrogates how these are experienced and understood by students themselves. Quantitative analyses compared one-year persistence rates between STEM Summer Bridge participants and multiple comparison groups across three cohorts (2022–2024). Results showed no statistically significant differences in persistence; however, STEM Summer Bridge participants demonstrated persistence rates comparable to or slightly higher …

Neoliberalism And The Crimes Of The Powerful: Transforming The State During The First Trump Era (2017-2021), Charles Brandon Lonon

Cal Poly Humboldt theses and projects

This thesis examines the way the American capitalist state transformed during Donald Trump’s first presidential term (2017-2021), especially focusing on neoliberal policy and the framework of the crimes of the powerful. This thesis aims to answer the question of how neoliberalism transformed the state under Donald Trump. Drawing on Nicos Poulantzas’ theory of authoritarian statism and Frank Pearce’s conception of crimes of the powerful, this thesis examines how the state becomes more authoritarian to protect capital accumulation and the capitalist class. The research shows that Trump weaponized authoritarian populist rhetoric that targeted women, immigrants, and vulnerable populations to build support …

Taking A Seat In The Circle: Decolonizing Gender Roles That Argue Against The Participation Of Feminine Bodies At The Big Drum, Juli Suzukawa

Cal Poly Humboldt theses and projects

The origins of the Big Drum can be traced back to the 1860s when Tail Feather Woman, a Dakota woman, had a vision of its creation as a tool of resistance. The Big Drum has since expanded and can now be seen at various Indigenous ceremonies and social events. However, there has been controversy regarding the participation of feminine and queer bodies. While reasons for this vary, it has also contributed to harm amongst Indigenous youths that have a more fluid stand on gender identity and may not conform to colonial “gender norms”. In this paper, I will explore how …

Assessing Coho Salmon (Oncorhynchus Kisutch) Distribution Using Traditional Sampling Methods In Conjunction With Edna On Trinity River Tributaries Within The Hoopa Tribal Boundaries, Ely D. Boone

Cal Poly Humboldt theses and projects

Detecting the presence of species using environmental DNA (eDNA) is a fast-growing field of study that shows much promise for population monitoring. In fisheries biology, eDNA is a potentially powerful tool compared to traditional fisheries monitoring techniques such as visual observation via snorkel surveys. When eDNA and traditional survey methods are employed in tandem, using the same spatial and temporal sampling design, eDNA often detects target species when traditional methods do not. In this study, instead of utilizing this paired study design, I implemented eDNA and snorkel surveys at different sampling scales with eDNA being collected at a single downstream …

Supporting Risky Outdoor Play Through Professional Development: A Quasi-Experimental Study Of Tk–6 Educators’ Attitudes, Justin Ross Burrill

Cal Poly Humboldt theses and projects

Children’s opportunities for active outdoor risky play have declined in many educational settings, despite evidence that manageable risk supports physical activity, self-regulation, confidence, resilience, and social participation. Educator attitudes and school culture may play an important role in determining whether children are offered developmentally appropriate opportunities for challenge, exploration, and autonomy. This quasi-experimental, single-group pretest-posttest study examined whether participation in a single-session professional development workshop was associated with changes in educators’ tolerance of risk in children’s play. Thirty educators attended a workshop focused on risky play, hazard-risk differentiation, inclusion of children with disabilities, loose-parts play, environmental affordances, and practitioner-informed implementation …

Reclaiming Presence: An Anthropological Study Of Digital Disconnection And Meaning-Making, Leslie De Paz

Cal Poly Humboldt theses and projects

Human attention is increasingly at risk in an unregulated digital ecosystem where overconsumption shapes neurological function, social interaction, and the ways people make meaning of everyday life. Dominant discourse around digital overuse tends to medicalize the problem, framing it as individual addiction or clinical dysfunction. In this thesis, I argue that such framing obscures what a cultural phenomenon is fundamentally, one in which people are actively questioning their relationship with technology, building awareness, and developing practices that help them slow down and reclaim agency within algorithmically mediated environments. This study draws on 22 semi-structured interviews with Gen Z and millennial …

Testing Adaptive Habitat Selection In Breeding Swainson's Hawks (Buteo Swainsoni), Elizabeth Meisman

Cal Poly Humboldt theses and projects

Adaptive habitat selection theory predicts that individuals preferentially select habitats that maximize or improve their fitness. However, patterns of habitat preferences may dampen with increasing population density and become decoupled from habitat quality when environmental conditions change. Such dynamics may be especially important in long-lived territorial species that exhibit site fidelity. One of the longest running raptor studies in North America has tracked an increasing population of breeding Swainson’s Hawks (Buteo swainsoni) in Butte Valley, California since 1985, where agricultural practices have shifted over the decades, providing an ideal system for studying these processes. Using nest records from …

Endocranial Lesions: A Paleopathological Study Of Late Medieval Skeletal Remains From Żelewo Poland, Francesca Aleen Meyer

Cal Poly Humboldt theses and projects

The site of Żelewo is located in a rural area of northwestern Poland, a region historically known as Pomerania. Skeletal remains from the cemetery associated with the archaeological site Żelewo 1-3, dating mostly to the 13th-15th centuries, are likely associated with a nearby Cistercian monastery. Numerous individuals from this site show evidence of endocranial lesions. To evaluate potential factors associated with the lesions, a differential diagnosis was performed based on macroscopic observations of endocranial lesion morphology and distribution. This study takes into account estimated age at death, biological sex, and other signs of pathology in the body. Potential confounding factors, …

“Thank You For Listening To Us”: Incorporating Community Context And Perspectives Into Sea-Level Rise Adaptation Planning For Fields Landing & King Salmon, California, Clara Riggio

Cal Poly Humboldt theses and projects

Fields Landing and King Salmon, California are two low-lying, coastal communities on Humboldt Bay (Wigi). These communities already experience coastal flooding during the highest astronomical tides each year, and flood conditions are expected to worsen as sea levels continue to rise. The Fields Landing & King Salmon (FLKS) Living with Water Project was created as a partnership between Humboldt County departments of Planning & Building and Public Works, along with support from social science researchers at Cal Poly Humboldt, including the author. In Chapter 1, I describe the co-production approach used throughout the project, including analysis of four dilemmas that …

Living With Water In Fields Landing & King Salmon: Community Knowledge Of Flooding And Adaptation Strategies In Coastal California, Kailin Sepp

Cal Poly Humboldt theses and projects

Known as “ground zero,” Humboldt Bay is among the most vulnerable areas to sea-level rise (SLR) due to geological and tectonic factors on the West Coast. While the land subsides, oceans rise, resulting in an area with one of the highest recorded rates of relative SLR on the West Coast. The residential communities of Fields Landing and King Salmon in South Humboldt Bay already experience regular coastal flooding. There is a need for better information and planning to understand the vulnerability to flooding/SLR and plan for adaptation. Typically, studies addressing flooding, such as vulnerability assessments and adaptation plans, are developed …

A Framework For Evaluating Riparian Climate Refugia In The Eel River Watershed, California, Farrah Tyler

Cal Poly Humboldt theses and projects

Climate change is increasing the need to identify and protect landscapes that support biodiversity through both habitat connectivity and climate refugia. Climate refugia are areas that remain relatively buffered from regional climatic change, enabling species to persist despite shifting environmental conditions. Riparian ecosystems can function as both movement corridors and climate refugia, yet methods for identifying these features and understanding the environmental processes that sustain them remain limited. In California's North Coast region, the identification and conservation of watersheds that may serve as climate refugia for sensitive plant and animal species will be essential for long-term ecosystem management and conservation. …

Assessing The Ecological Drivers Of Wildfire Hazard Mitigation Of Fuels In The California Home Ignition Zone, Christopher David Benterou

Master's Theses

Consecutive years of devastating home losses to wildfire indicate the need for home fuel reduction and construction improvements. Existing research correlates house survival with modifications to the home ignition zone (HIZ) and is required in high fire hazard areas of California (CA). Mitigations, designed to disrupt continuous fuel patterns, (e.g., separating surface and canopy fuels), can also introduce ecological changes that can alter overall code compliance. Previous compliance studies used respondent and agency-generated data, which may lack accuracy. Assessing additional house and ecological features (e.g., canopy cover and construction) would improve prediction of compliance, but these relationships are poorly studied. …

Small-World Simulations: A New Method To Test The Effect Of Legal Rules, Johannes Kruse

Coase-Sandor Institute for Law & Economics Research Paper Series

Small-world simulation exposes an artificial society to a legal rule and observes what its members do. The agents are driven by language models: their conduct is not stipulated in equations but reasoned in their own words. The architecture can be turned on any legal regime; personalized speed limits are the demonstration, chosen because rational-choice and behavioral predictions there conflict. Validated against documented driving patterns, the simulation generates behavior no one wrote into it. Because language models are trained on what people say rather than do, the method estimates orderings, not levels: a benchmark, not a substitute for evidence.

The Rise Of Global Collaboration In China Policy Research: Evidence From Bibliometric Network Analyses, 2000–2025, Yu Xiao, Aaron Ley, Ping Xu

Political Science Faculty Publications

This study examines the evolution of China policy research and its growing role in global policy scholarship. Using bibliometric and social network analyses of 326 articles published in 20 high-impact political science journals from 2000 to 2025, we trace the field’s expansion, identify key thematic concentrations, and document the emergence of robust international collaboration patterns. Cross-national co-authorship networks reveal a clear transition from a fragmented, Western-centered structure to a dual-hub system anchored by Mainland China and the United States, while institution-level networks show that leading Chinese universities have become central collaborators and Hong Kong institutions continue to serve as critical …

Evolving Contexts And Diverging Strategies: Federalism And The Politics Of Immigrant Welfare Exclusion In The Us, Ping Xu, Ling Zhu, Sebastian Ege

Political Science Faculty Publications

The intersection of immigration and welfare has taken a central stage in the politics of social policy and garnered increasing scholarly attention in welfare politics research. While prior research has examined how immigration affects welfare support and welfare generosity in the US, less is known about the determinants of immigrant-related welfare policies. This paper investigates how state-level policymakers shape immigrant welfare policies in response to changing social and economic state contexts across the U.S. states from 2000 to 2020. Using data from the Urban Institute's Welfare Rules Database, we create a policy index of welfare inclusion of immigrants to track …

The Operation And Control Strategy Of Microgrids: A Brief Review, Mohammad Alam, Salsabila Zaman

Electrical Engineering Student Publications

A microgrid is an effective approach for integrating various distributed energy resources to meet local energy demand. It possesses the capability to operate independently or in conjunction with the main utility grid. Typically, a microgrid is a small-scale power system (usually several megawatts or less) comprising three primary components: the ability to function in both grid-connected and islanded modes, distributed power generation sources, and autonomous control centers. Microgrids enhance system resilience by ensuring uninterrupted operation during grid disturbances. Additionally, they are environmentally sustainable and contribute to improved power quality. As a crucial element of modern power systems, microgrids can effectively …

This study sought to identify the essential knowledge and skills needed by undergraduate AST degree program students from the perspectives of university-level faculty across the …

Speaking For The Families: Organizational Socialization Of Military Spouses In Volunteer Leader Positions, Virginia Klaus

Murray State Theses and Dissertations

Military spouses holding volunteer leadership positions in military unit family readiness groups, provide a link between commanders and families of service members. They act within military organizations as the only official voice of spouses, a stakeholder group recognized as influential in retention rates and force readiness. Despite their importance, military spouses are often portrayed in research as passive members, taking on roles to meet the expectations of their peers and military organizations. That contradicts historical evidence of military spouses as active organizational members who have socialized other spouses, and as family advocates who have challenged military organizational practices and policies. …

Personality Assessment Inventory Profiles In Adults Seeking Autism Spectrum Disorder Assessment, Emily Kinsey

Murray State Theses and Dissertations

The current study aimed to examine differences in interpersonal functioning and response validity among adults presenting for autism spectrum disorder (ASD) assessment compared to those seeking services for other clinical concerns. The study used archival data from 238 client files collected in an outpatient clinical setting. Interpersonal functioning was assessed using the Dominance (DOM), Warmth (WRM), and Nonsupport (NON) subscales of the Personality Assessment Inventory (PAI; Morey, 1991). Response validity was evaluated using the Negative Impression Management (NIM) and Positive Impression Management (PIM) scales. A multivariate analysis of variance (MANOVA) showed no significant group differences across DOM, WRM, and NON …

Wired For Inclusion: Leveraging Strengths Of Neurodivergent Special Educators, Brok Hess, Teresa Clark Ed.D.

Murray State Theses and Dissertations

Special education teachers face unique challenges, and neurodivergent special educators possess distinctive strengths that can allow them to excel in the classroom. However, barriers, stigma, and ableism persist that have prevented neurodivergent individuals from accessing this career, receiving support, and thriving as special educators. Self-efficacy and executive functioning both correlate to success and retention within education. This research analyzed the relationship between special education teachers’ self-efficacy and executive functioning, specifically among neurodivergent special educators. Results concluded that a significant positive correlation exists between neurodivergent special education teachers’ executive functioning and self-efficacy. Attention to these results will highlight the importance of …

Don’T Give The Fae Your Name: Focus Of Attention And Victim Blaming, Entropy Cramer

Murray State Theses and Dissertations

Victim-blaming is thought to be a result of the fundamental attributional error, where people over-emphasize internal attributions about the victim. Despite this, there is little literature on manipulating the focus of attention and the result for victim-blaming. People who are high in rape myth acceptance tend to visually focus on the victims longer (Süssenbach et al., 2015). Rempala and Bernieri (2005) found that adding irrelevant information, such as height and weight, to the trial about the victim increased victim-blaming compared to when it was absent. The current study investigated if relevant information about the victim and perpetrator changed the amount …

Out In The Arena: Examining The Lgbtq+ Experience In Ihsa, Katharine C. Didier

Murray State Theses and Dissertations

This study investigated factors influencing Intercollegiate Horse Show Association (IHSA) LGBTQ+ riders’ perceptions of inclusion, safety, and belonging, with the hypothesis that teams with diversity and inclusion policies would be perceived as more accepting. An online survey was developed to gather information from self-identified LGBTQ+ IHSA students. Questions covered demographics, team environment, and perceived inclusivity within their equestrian programs. Question types included multiple choice, Likert-type, short answer, and open-ended. IHSA coaches were asked to share the survey link with team members. Students were able to respond anonymously. The survey was open for 8 weeks. Reminders were sent out at 3 …

Attention Or Affect? Evaluating The Discriminant Validity Of Cpt-3 Performance, Gavin F. Price

Murray State Theses and Dissertations

The Conner Continuous Performance Test Third Edition (CPT-3) is a behavior-based measure of attention-related problems commonly used to assess Attention-Deficit/Hyperactivity Disorder (ADHD). Research into the discriminant validity of the CPT-3 remains limited, particularly regarding the influence of internalizing symptoms such as anxiety and depression on performance. The current study examined whether CPT-3 performance was more strongly associated with cognitive indicators of inattention or internalizing symptoms, such as depressive or anxious symptoms. Archival data from 105 adult clients at Murray State University Psychological Center was analyzed. Cognitive inattention was measured using Verbal Comprehension Index (VCI) – Working Memory Index (WMI) discrepancy …
