Presence Without Exposure: Feminist Pedagogy In The Home-As-Classroom, Kristy Kelly

Feminist Pedagogy

This commentary reflects on teaching during and after COVID-era remote instruction, when the classroom moved into students’ homes and “presence” became equated with visibility. Drawing from a course-based study conducted with students, I describe how patterned differences in men’s and women’s experiences of online participation illuminated the unequal costs of being seen—costs shaped by privacy, domestic constraints, and the risks of interpretation. I argue that feminist pedagogy requires decoupling engagement from visual exposure and designing participation around those most vulnerable to surveillance and stigma in online spaces. The essay outlines practical shifts—camera-optional norms, modality-equivalent participation, structured breaks, and low-stakes entry …

Sitting Together: How Proximity Impacts The Classroom Success Of Undergraduate Women In Engineering, Cassandra M. Savukinas, Kayla D. Taylor, Ashley Lear

Feminist Pedagogy

Despite increased efforts, the engineering field remains predominantly male, particularly within higher education environments. Seating arrangements in the classroom for female undergraduate engineering students can greatly impact their comfort, participation, and academic performance in the classroom. In a 2025 study, it was found that male and female students have differing experiences related to comfort, participation, and academic performance when seated near other students of the same gender (Savukinas et al., 2025). Faculty can help students succeed by understanding how seating dynamics impact students’ experiences in the classroom. By allowing students to choose their own seating arrangements and creating interactions in …

Access Intimacy In The Feminist Classroom: Co-Creating Course Policies, Expectations, And Access Measures As Feminist Disability Praxis, Krystal Cleary

Feminist Pedagogy

In this essay, I outline an activity to foster access intimacy (Mingus, 2011) in the feminist classroom through students’ co-creation of course policies, expectations, and additional access measures. This activity transforms the classroom into a praxis laboratory wherein students analyze the normative structures that shape their hyperlocal classroom context and practice building environments characterized by interdependent solidarity rather than atomized competition. As feminist disability praxis, this activity centers the knowledge of disabled, chronically ill, and neurodivergent scholars and students; in doing so, it customizes the classroom to a diversity of learners and builds adaptability for responding to unforeseen challenges into …

Environmental Impact Of Preventative Fire-Retardant Products On Soil Chemistry, Elisabeth Kraycik

Master's Theses

Human-caused ignitions account for most wildfires in the United States, particularly along roadsides, utility corridors, and other high-risk infrastructure where fine fuels are abundant and ignition sources are concentrated. These settings are often embedded within grassland and shrubland ecosystems, where fires spread rapidly and can threaten nearby communities and assets. Preventative fire-retardant products (PFRPs) have emerged as a promising strategy for reducing ignition likelihood in these environments. Unlike traditional aerial retardants applied during active suppression, PFRPs are designed for annual, pre-season application to ignition-prone locations. Despite their growing use, the environmental consequences of repeated PFRP applications remain poorly understood, especially …

Xenaform Algorithm, Alden Ulysses Quandt

Architectural Engineering

This project develops a computer-generated form-finding process for XenaForms, a discrete folded-plate shell system made from rigid triangular panels and hinge-like edge connections. Using Blender and Python, the workflow generates an initial top-down triangular strip, expands it into a fuller shell through stability-guided growth, checks the resulting geometry against a local stability rule, and culls unstable or erroneous elements. The algorithm translates XenaForm stability principles into a usable design tool while also accounting for constructability through sheet-size constraints and geometric collision checks. The result is a Blender-based workflow that can rapidly produce stable, varied XenaForm models for architectural, sculptural, and …

The Regulatory Costs Of Wine Production In Napa County, Lynn Hamilton, Michael Mccullough

Agribusiness

Unlike other food products, commercial alcoholic beverage production has been subject to federal regulation and taxation since the founding of the United States, with specific wine taxes being levied during the wartime Emergency Revenue Act of 1914 (Cilluffo and Gravelle, 2024). Since then, taxation and regulations have expanded, with many new laws originating at the state level. Additional regulatory costs, combined with the current decline in consumer demand raise questions regarding the long-term viability of California wine production. Napa County Farm Bureau contacted Cal Poly to assess baseline conditions in the industry by conducting a case study of regulations accruing …

Evaluating Fungicide Programs For Grapevine Disease Management And Fungicide Sensitivity Monitoring, Abraham Ahumada

Master's Theses

Grapevine diseases, such as powdery mildew and Botrytis bunch rot, require repeated fungicide applications to maintain fruit quality and reduce yield losses. However, fungicide performance can vary among products, application programs, disease pressure, and pathogen sensitivity. This thesis evaluated fungicide programs for control of powdery mildew in ‘Chardonnay’ grapes and assessed fungicide sensitivity of Botrytis cinerea isolates collected from California vineyards.

Powdery mildew, caused by the fungal pathogen Erysiphe necator, is a major threat to the production of Vitis vinifera grapes worldwide. Because powdery mildew management relies heavily on fungicide applications, field evaluations are needed to compare the efficacy …

Hand Mapping: Our Sexual Health Is (Not) In Our Hands, Laura L. Ellingson

Feminist Pedagogy

This Original Teaching Activity introduces hand mapping, an assignment based on the body mapping method, in the context of a communication and gender studies course. Hand mapping can be adapted to interpersonal, organizational, intercultural, and media courses that address identities, intersectionality, communication, culture, and power in different contexts and mediums. Students outline their hands on paper and artfully embellish them as a visual representation of important takeaways or lessons they learned in the course in response to the prompt, “Our sexual health is (not) in our hands.” Students write an “artist’s statement” explaining meanings of color, symbolism, and design.

Tilly Norwood And The Promise Of Frictionless Creation: Feminist Pedagogy In Ai-Saturated Classrooms, Jill N. Fredenburg

Feminist Pedagogy

This article examines how feminist pedagogy can intervene in AI-saturated classrooms by foregrounding refusal, embodiment, and critical engagement with what I term the muddy algorithms of generative systems. As institutions increasingly normalize AI as an inevitable educational tool, this work challenges that assumption by situating AI within broader structures of power, labor, and extraction. Drawing on classroom experiences in media and communication courses, I use the case of Tilly Norwood, an AI-generated “actress,” to explore how automation reproduces gendered expectations of availability, consent, and creative labor. The concept of muddy algorithms names the opaque, uneven, and value-laden processes through which …
