Planting Roots: A Pedagogy Of Action, Veronica Rose Popp, Danielle Phillips-Cunningham

Feminist Pedagogy

We discuss how we put feminist pedagogies into action while developing a collaborative research and writing project about Nannie Helen Burroughs (1879-1961). We also explore how our collaborative research project influenced the development of a happy, fruitful, and long-lasting research partnership that broadens the conversation about incorporating feminist teaching practices into higher education. Burroughs set students on ways to find their own pathways, affecting change in ways they found most important. We engaged in our project with similar commitments.

Physics

As brackish turbid waters exit San Francisco Bay, one of the largest estuaries in the U.S. West Coast, they form the San Francisco Bay Plume (SFBP), which spreads offshore and influences the Gulf of the Farallones (GoF), an ecologically significant region in the California Current System that is also home to three National Marine Sanctuaries. This paper provides the first observationally based investigation of the spatio-temporal variability of the SFBP, using a plume tracking algorithm applied to more than two decades (2002-2023) of ocean color data from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard satellites Aqua and Terra. The …

Measurements Of Spinal Posture During Common Strawberry Picking Positions Using Inertial Measurement Units, Madeline E. Everson

Master's Theses

Physically demanding professions, such as agriculture, put people at an increased

risk for experiencing back pain. This is due to the awkward and harmful postures sustained

throughout their workday. While studies have been done demonstrating that back pain is

prevalent amongst this community, most do not collect motion capture (MoCap) data,

leaving the specifics of the kinematics, such as the amount of time spent in harmful

postures, unknown. Unfortunately, MoCap data is typically limited to that of a lab or

facility where the cameras are housed. Therefore, this study aimed to mitigate the

inaccessibility of traditional MoCap by validating that …

Drug Delivery, Disulfide Crosslinked Hydrogel Coating For Polydimethylsiloxane (Pdms) Implant Materials, Paul A. Contos, Paul Anthony Contos

Master's Theses

Though polydimethylsiloxane (PDMS) is often used in medical devices due to its desirable mechanical properties and biocompatibility, its surface is often prone to bacterial adhesion. This is especially a problem for catheters, where bacteria can adhere and form biofilms that can in turn result in Urinary Tract Infections (UTI). In order to deter the presence of UTI causing bacteria on PDMS catheters, methods were developed to formulate a disulfide crosslinked hydrogel coating and create a methodology to allow adhesion to a PDMS substrate. The hydrogel coating discussed in this paper will be synthesized by chemically crosslinking stimuli-responsive vesicles, that carry …

A Wearable-Based Approach To Spinal Posture Tracking And Assessment, Sydney Marie Sherman, Noah Jeffery

Biomedical Engineering: Graduate Reports and Projects

This paper describes the design, manufacturing, and testing of a novel spinal posture tracking wearable device with embedded sensors. Currently on the market, most of the spinal posture tracking devices only focus on one segment of the spine and therefore do not track the entirety of human posture. The objective for this project was to create a wearable device in the form of a “smart shirt” that offers insights into posture trends throughout the day by tracking the entire spine. To begin the project, multiple designs were developed for the sensor array and wearable materials. These concepts were compared against …

The Buzzard In The Abolitionist Sea; An Examination Of Maritime Suppression, Imperial Policy, And The Slave Trade Through The Royal Navy’S Hms Buzzard, 1830s-1840s, Sean Joaquim Coudray-Pereira

Master's Theses

Analysis of the Royal Navy through the microhistory of the HMS Buzzard following the abolition of the slave trade between 1807 and the 1840s by Great Britain offers insight into the moral ambiguities and complexities of the humanitarian mission. The historiography of the slave trade has primarily focused on the moral and economic ideology behind its abolition, pitting one against the other. Applying a micro-historic approach highlights the nuances of both arguments, and through the HMS Buzzard’s crew, captives, disease, voyages, and legal battles accentuates the blend of both argument approaches. The case study of its longevity through all six …

This essay introduces the Slow Leadership Framework as a humanizing, social justice-oriented alternative to conventional leadership models. Challenging Eurocentric, hierarchical approaches that prioritize efficiency over human connection, Slow Leadership integrates three complementary practices: Circle Process, Self-Compassion, and Deep Listening. Circle Process creates equitable spaces for dialogue that value marginalized perspectives; Self-Compassion disrupts internalized patterns of self-criticism and perfectionism; and Deep Listening transforms communication by prioritizing multisensory perception and awareness. Particularly resonant in higher education contexts, this framework offers practical implementation strategies for educators, administrators, and community partners seeking to dismantle systemic barriers, foster inclusive environments, and redistribute power. Through qualitative …

Creating And Re-Energizing Communities Of Meaning Throughout A Course, Nancy A. Heise, Anum Ahmed

Feminist Pedagogy

We propose a feminist course approach wherein instructors build what Amie Macdonald (2002) called "communities of meaning" in their classrooms (p.120). Through an intentional focus on supporting students' 1) individual identities, 2) holistic well-being, and 3) epistemic "buy-in" to classroom content, students will connect more deeply not only to themselves and their classmates, but also to the course material. We suggest four community-building touchpoints as a starting point for instructors looking to integrate this course approach. We start with an activity to lessen awkwardness around first-day name pronunciation. We emphasize the importance of creating collaborative classroom expectations with students, and …
