"We'll Never Get This Opportunity Again": Lived Experiences Of Platform-Based Gig Workers, Catey Hoehn

Cal Poly Humboldt theses and projects

Platform-based gig work has rapidly expanded in the United States, leading to growing concerns about economic precarity, algorithmic management, and the sustainability of labor performed through apps. Gig work has been accused of fostering exploitative conditions, masking control through the language of flexibility, and deepening cycles of debt and insecurity for workers. However, the lived experiences of gig workers often reveal complexities that differ from public narratives and company portrayals. This thesis builds on sociological studies of labor precarity to examine how platform-based gig workers experience, internalize, and resist algorithmic control. Utilizing qualitative semi-structured interviews, fifteen rideshare and delivery drivers …

Representation In Higher Education: A Closer Look Into Cal Poly Humboldt’S Hsi Designation Through The Courageous Cuentos Retrospective, Audriana Peñaloza

Cal Poly Humboldt theses and projects

When it comes to representation in education, it can be inconsistent. For many students of color, it can either feel like their identity is included in the conversations in the classroom and on campus, or it can feel like an afterthought — especially in higher education. Many colleges in the country are classified as a Hispanic Serving Institution (HSI), Cal Poly Humboldt being one of them. This designation claims that Humboldt has the resources and support systems for all students of color, especially for the Hispanic/Latine population on campus.

All Red Inside: Embodied Metaphor In Clive Barker's Books Of Blood, Ian Vargas

Cal Poly Humboldt theses and projects

The collection Books of Blood is an anthology series of short stories written between 1984 and 1985. Only two, the very first and last, have any unifying story. For our purposes we will be looking at stories in particular that exemplify the themes I am speaking about. Barker's writing often heavily focuses on the ways that the body stands outside the control of the individual, something that a person resides in and must always rely upon, but is not actually in their control in most senses. His horror explores the ways in which the human body is both the first …

Comparison Of The Division And Fairness Of Household Labor Between The 1980s And Early 2000s, Madeline Rose Provins

Cal Poly Humboldt theses and projects

The purpose of this thesis is to examine change in the gendered division of household labor between the 1980s and early 2000s. The division of household labor has historically been inequitable reflecting parallel social hierarchies, power imbalances, and systemic inequalities outside the home.

I used a cohort sample of 1,157 respondents combined from the 1988 Wave 1 of the National Survey of Family and Households (NSFH) and the 2003 Wave 3 to test four hypotheses related to gender and household labor. I found that between 1988 and 2003, the gender gap closed in mean hours a week devoted to indoor …

Campesino World-Building: Stories Of Migration, Memory, And Care In The Tension Of The Colonial Frame, Chelsea Ríos Gómez

Cal Poly Humboldt theses and projects

Campesinos, often reduced to the label of “farmworkers”, are too often seen only through the lens of their labor within profit-driven systems. This thesis disrupts that limited narrative by illuminating the rich, expansive nature of vivencias campesinas, ways of being that transcend capitalist measures of value. These vivencias are lived, embodied experiences rooted in campesino lifeways, encompassing cultural, spiritual, and relational practices that nurture and sustain life.

My research is guided by four central questions: (1) In what ways have campesinos in pixley resisted exploitative labor systems, and how can this resistance be understood as a form of care labor? …

From The Ashes: Lessons In Community Recovery From 2020 Wildfires In Northern California And Southern Oregon, Catriona Grace Barr

Cal Poly Humboldt theses and projects

As wildfires grow in size, frequency, and severity, it is increasingly important to understand how communities recover from destructive fire. Working closely with partner organizations, I examined post-fire recovery in three communities impacted by the record-breaking 2020 fire season: Talent and Phoenix, Oregon; Happy Camp, California; and Ruth and Zenia, California. While each of these communities experienced severe losses as a result of fire, they embody a range of social and economic contexts. Evaluating recovery three to four years after fire, I explored how these distinctly different communities have defined and worked towards post-fire recovery. Through 76 interviews with fire …

North American River Otter (Lontra Canadensis) Prey Selection Of Wintering Waterbirds In A Wetland Complex, Gina Yael Culver

Cal Poly Humboldt theses and projects

Generalist predators are assumed to take a wide variety of prey throughout an annual cycle, often switching between food sources depending on availability. Prey selection is often studied by way of variables such as prey age class, body size, and various topics related to anti-predator behaviors, all variables used to measure how predators target prey. Following prior studies in coastal Northern California documenting that river otters (Lontra canadensis) had selected waterbirds as prey, we identified undigested prey items in scat to evaluate prey selection of waterbirds at the Arcata Marsh and Wildlife Sanctuary (AMWS). We compared feathers found …

Just Keep Swimming: Outmigration Survival Of Upper Klamath Basin Juvenile Chinook Salmon, James M. Whelan

Cal Poly Humboldt theses and projects

The removal of four impassable hydroelectric dams on the Klamath River provides salmonids with the opportunity to recolonize their historic range in the upper Klamath River watershed. However, successful reestablishment of salmon populations requires juvenile salmon born in Oregon's upper tributaries to safely migrate downstream through the river's upper reaches. This stretch of the Klamath River, immediately downstream of Upper Klamath Lake, presents multiple migration challenges, including two flow-control dams not scheduled for removal (Link River Dam and Keno Dam), significant water diversions, and water quality issues. To evaluate these challenges, I conducted experimental releases of radio-tagged juvenile Chinook salmon …

Exploring The Placebo Effect On The Cortisol Stress Response, Povheng Yam

Cal Poly Humboldt theses and projects

The placebo effect is well-studied on pain perception and is often observed to have a pain-reducing effect in patients. A few studies suggest that the placebo effect can influence physiological changes in people. To date, not many studies have examined the placebo effect on stress; thus, the current study explored the placebo effect on participants’ cortisol stress response and self-reported stress while undergoing a modified acute stress task, the Sing-a-Song Stress Test (SSST). The current study includes 44 participants (22 in the control group and 22 in the treatment group). A deceptive stress-reducing tincture (filled with water) was used as …

Factors Associated With The Biomass Of Yellowfin Tuna, Thunnus Albacares, At Fixed Fish Aggregating Devices (Fads) In The Galapagos Islands, Sarah Payton Moreau

Cal Poly Humboldt theses and projects

The Galapagos Marine Reserve was established in 1998 to protect biodiversity and reduce fishing pressure by only allowing artisanal fishing. Despite its small scale, artisanal fishing has impacted vulnerable, slow-growing species. As a result, managers are attempting to redirect fishing toward faster-growing, migratory species like yellowfin tuna. To support this shift, four fixed fish aggregating devices (FADs) were deployed in 2016 off Isabela, Floreana, and San Cristóbal islands. These anchored buoys were equipped with solar-powered sonars to estimate pelagic fish biomass,primarily yellowfin tuna,within the upper 100 meters of the water column. Although data was collected at four FADs, the analysis …

Fleeing Structural Stigma: Psychological Outcomes For Transgender And Gender-Diverse Internally Displaced Persons, Max E. Cartagena

Cal Poly Humboldt theses and projects

In 2025, at least 1,000 bills targeting transgender and gender-diverse (TGD) individuals were introduced across the United States, contributing to an environment of escalating structural stigma. As a result, many TGD individuals have relocated from states with high levels of stigma to those with lower levels in search of safety, access to care, and social affirmation. This study examines these individuals as internally displaced persons (IDPs) and is informed by refugee psychological literature, as both experiences arise from coercive structural forces that compel individuals to relocate. This perspective highlights the involuntary nature of their migration, driven by the need for …

The Effects Of Chronic Absenteeism On Average Daily Attendance Funding In Humboldt County Elementary Schools, Corabelle A. Esmailian

Cal Poly Humboldt theses and projects

Chronic absenteeism is linked to poor academic performance and lower social-emotional skills, both of which can have long-term effects on students and their communities. The California Department of Education uses average daily attendance (ADA) to determine most of the funding that public schools receive. When a student is absent, their school loses a portion of potential funding for that day. This study explores chronic absenteeism’s impact on the funding of Humboldt County’s elementary schools with a sequential exploratory research strategy and critical systems lens. Interviews with elementary administrators were conducted using a phenomenological approach to understand how this affects their …
