Establishing A Monitoring Framework To Evaluate Impacts Of Grazing Exclusion And Inform Restoration At Santa Rita Ranch, Annie Booth, Annie Booth

Master of Science in Environmental Sciences and Management Projects

Santa Rita Ranch is a 1,750-acre cattle ranch in Templeton, California, that was privately owned and continuously grazed for the past 70 years. In 2021, The Land Conservancy of San Luis Obispo (LCSLO) acquired the property, and in the winter of 2022, they built a fence that bisects the ranch, excluding the cattle from 800 acres to preserve the riparian habitat. The LCSLO is currently defining the ecological baseline for the ranch to inform future management decisions. Given that cattle grazing has many environmental tradeoffs, they wanted to establish a long-term monitoring study to understand how relieving the pressures of …

Pumping-Induced Drawdown Of Streams In Proximity To Agricultural Wells, Sara Alina Sternberg

Master of Science in Environmental Sciences and Management Projects

In the context of unprecedented drought and aquifer overdraft in California, understanding surface water and groundwater connectivity have become increasingly important. While there is a clear understanding of how wells induce drawdown in aquifers (Theis, 1935; Hantush, 1965), secondary effects on local streams have not fully been considered. Current mathematical models targeting aquifer drawdown do not address stream drawdown response in aquifer-stream systems with strong connectivity; instead, they assume the stream to be a constant head boundary. In the drought-stricken and summer-dry climate of California, streams often run dry for months out of the year, which is currently not reflected …

The Methods Of Communication And Education Used To Train Forest And Fire Personnel Through The Swanton Pacific Ranch, Christine Brittney Johnson

The Swanton Pacific Ranch Fuels Management Training Program is Cal Fire affiliated and provides online and in person training to assist in equipping fire and forest professionals throughout California with the necessary skills to be successful fire and forest practitioners and managers. An exit survey was offered to all workshop participants after the Swanton workshop concluded. The survey was answered by 331 Swanton workshop participants to assess the effectiveness of the training program, the educational practices used to teach participants, and what factors of a …

Environmental Controls On Soil Organic Matter Fractions In Post-Fire Landscapes, Alexis Heuer

Master of Science in Environmental Sciences and Management Projects

In the past few decades, the world’s climate is being altered by anthropogenic forces such as the increase in carbon dioxide (CO2) emissions due to fossil fuel combustion (Paraschiv and Paraschiv, 2020). In California, the impacts of increased CO2 concentrations have created longer fire seasons, warmer temperatures, and increased lightning strikes which allow for wildfires to become more frequent, severe, and larger in scale (Westerling et al., 2006). Wildfires of this magnitude result in acceleration of landscape scale processes such as erosion and aggregation which in turn affects soil organic matter (SOM), the basis of soil health (Gonz´alez-P´erez et al., …

Fire Effects On Soil Organic Matter In The Creek Fire, Gracie E. Doolin

Master of Science in Environmental Sciences and Management Projects

Wildfires have increased in frequency and severity over the past few decades due to the increased concertation of CO2 emissions from anthropogenic influence. Soil carbon (C) sequestration has been identified as a climate change mitigation strategy; however, the influx of large-scale wildfires has accelerated landscape processes such as erosion, reducing soil aggradation, and soil C and nitrogen (N) protection. This trend is highlighted by the Creek Fire that occurred in September 2020 and burned 379,895 acres in the Sierra National Forest. This research is designed to close the knowledge gap regarding the impact of burn severity on soil organic matter …

Assessing Environmental Impact Of The Built Environment By Adopting Life Cycle Design: Using Swanton Pacific Ranch As A Case Study, Hope E. Springer

Master of Science in Environmental Sciences and Management Projects

To combat the carbon emissions contributed to the atmosphere by the built environment, it is imperative that low-embodied-carbon materials choices be prioritized throughout the building design process. To achieve this, this professional project creates an Excel-based, open source, and user-friendly tool for the construction sector to make design decisions that prioritize the sustainability of structures, as one such tool does not currently exist. The use of OpenLCA software and the EcoInvent34 database are utilized to calculate the environmental impact of 25 different building materials, as well as energy and electricity consumption. Swanton Pacific Ranch (SPR) in Santa Cruz County is …

New God Video Game, Evan Springer

Computer Science and Software Engineering

Artificial Intelligence is used in all sorts of ways in various types of media. AI is often applied to Interactive entertainment such as video games. One of the most important parts of designing an AI for a video game is considering how “intelligent” it should be for better user enjoyment. For instance, making the AI too simple can cause frustration and impatience in the player, and making the AI too advanced can result in unexpected side effects and/or the player not getting personal satisfaction from in-game accomplishments. My goal for this project was to figure out what level of “intelligence” …

Laboratory Glovebox, Jackson T. Tenne, Noah Fitzgerald, Scott Stirling, Danny Ho

Mechanical Engineering

The Laboratory Glovebox project aimed to create an affordable, functional, ready to use, airtight workstation enabling Dr. Ramanan Sritharan to continue his research of the mechanical properties of nanomaterials. When airborne, nanomaterials are a health risk if inhaled, so the design requires a hermetic seal to protect the user. The design was meant to emulate features of the glovebox used by Dr. Sritharan during his PhD research, but was optimized to meet a budget of $3000, much cheaper than comparable alternatives. Key design features included acrylic panels, a transfer chamber, glove mounts, and a main access door, all sealed to …

Physical Treatments To Modify The Functionality Of Carrot Pomace And The Development Of An Enhanced Beef Patty, Jordan O.A Richards

Master's Theses

Approximately one-third of the global food produced for human consumption is lost or wasted somewhere along the food chain. Carrots are one of the most important and widely produced root vegetables grown worldwide; they are rich in many beneficial bioactive compounds such as dietary fiber and carotenoids. Every year, an estimated 29% of processed carrots are lost as waste. The U.S. is the 3^rd largest producer of carrots worldwide, 85% of which come from California. During carrot juice processing, up to 50% of the raw material remains as carrot pomace. Carrot pomace may contain up to 55% total dietary …

Knowledge And Use Of Paced Bottle-Feeding Among Mothers Of Young Infants, Alison K. Ventura, Vivian M. Drewelow

Kinesiology and Public Health

Objective: To describe mothers’ awareness and use of paced bottle-feeding (PBF) and to investigate whether the use of PBF was associated with maternal characteristics and infant feeding practices.

Methods: Cross-sectional, online survey. Participants were mothers of infants < 12 months of age (n =197). Participants self-reported their awareness and use of PBF, demographic characteristics, and infant feeding practices.

Results: Of the 41% of participants who indicated they had or maybe had heard of PBF, 23% used PBF and 35% sometimes used PBF. Use of PBF was not associated with mother or infant characteristics. Participants who used PBF were significantly less likely to encourage their infant to finish the bottle (odds ratio,0.04; 95% confidence interval, 0.01−0.79).

Conclusions and Implications: Paced bottle-feeding was …

Functional Nanocomposite Coatings For Use In Food Packaging, Camden N. Webb

Master's Theses

Plastics are a class of materials known for their cost and property advantages, increasing significantly in their usage worldwide. Unfortunately, these benefits come with an increasingly concerning environmental impact. A combination of inadequate disposal options and combinations of materials have led to environmental disasters that will impact generations. One of the worst areas for plastic waste is food packaging. Plastic as a material generally excels at durability and longevity, but as food packaging, it outlives its intended purpose by several orders of magnitude. This leads to plastic food packaging materials sitting in landfill or leading to the environment for hundreds …

Mate Choice And Sexual Conflict In A Livebearing Fish, Julia C. Kasper

Master's Theses

Eavesdropping occurs when a receiver extracts information from an interaction without directly engaging with the signaler. Eavesdropping has been shown to be an effective way of evaluating the quality of potential mates and their abilities in male-male competition, without having to directly interact with them, thereby reducing energy costs and mating harassment. Girardinus metallicus is a livebearing poeciliid fish endemic to Cuba whose mating system is dominated by mating harassment in the form of sneak copulations, persistent displaying, and male-male aggression. G. metallicus has a male specific polymorphism in both melanin coloration and behavior. Males with melanin coloration are known …

Phase Distribution Of Nickel, Chromium, And Cobalt In Seawater At Olivine-Enriched Beaches: Implications For Carbon Capture By Enhanced Silicate Weathering, Nathaniel J. Padrnos

Master's Theses

The application of olivine to coastal areas is a proposed method of removing carbon dioxide from the atmosphere for climate change mitigation. Olivine is abundant and dissolves relatively fast, but it contains trace amounts of nickel (Ni), chromium (Cr), and cobalt (Co) which may be toxic to marine biota in cases of widespread coastal olivine spreading. Prior studies have suggested that Ni concentrations in marine sediments and/or the overlying water column due to olivine dissolution could be a limiting factor for its carbon capture potential. Therefore, it is critical to understand and model the processes affecting trace metal bioavailability after …

Subject-Specific Human Knee Fea Models For Transtibial Amputees Vs Control Tibial Cartilage Pressure In Gait, Cycling And Elliptical Training, Ali Yazdkhasti

Master's Theses

Millions of individuals around the globe are impacted by osteoarthritis, which is the prevailing type of arthritis. This condition arises as a result of gradual deterioration of the protective cartilage that safeguards the ends of the bones. This is especially true of transtibial amputees, who have a significantly higher incidence of osteoarthritis of the knee in their intact limb than non-amputees. Engaging in regular physical activity, managing weight effectively, and undergoing specific treatments can potentially slow down the advancement of the disease and enhance pain relief and joint function. Nevertheless, the relationship between the type of exercise and its impact …

Avoiding Anthropomoralism, Julian Friedland

Between the Species

The Montreal Declaration on Animal Exploitation, which has been endorsed by hundreds of influential academic ethicists, calls for establishing a vegan economy by banning what it refers to as all unnecessary animal suffering, including fishing. It does so by appeal to the moral principle of equal consideration of comparable interests. I argue that this principle is misapplied by discounting morally relevant cognitive capacities of self-conscious and volitional personhood as distinguished from merely sentient non-personhood. I describe it as a kind of anthropomorphizing moralism which I call anthropomoralism, defined as the tendency to project morally relevant characteristics of personhood onto merely …

How Many Trans People Get Abortions? An Introduction To Critical Data Studies, Derek P. Siegel

Feminist Pedagogy

As abortion restrictions escalate, scholars and activists have struggled to incorporate transgender individuals into their organizing efforts. On one hand, most people recognize that not everyone who needs an abortion identifies as a woman. On the other hand, many are reluctant to abandon or complicate the rallying cry of abortion as a "woman's issue." Caught at a perceived crossroad, stakeholders wonder, "how many transgender people actually get abortions?" in the hopes that this number might guide their social movement strategies. In this assignment, students will use the concept of critical data studies to examine the politics of how we collect …

Review Of Dan C. Shahar’S Why It's Ok To Eat Meat And Per Bauhn’S Animal Suffering, Human Rights, And The Virtue Of Justice, Josh Milburn

Between the Species

It’s tricky to find decent defences of meat-eating of the kind practiced by most westerners. I was thus intrigued to pick up two short books defending meat-eating. Dan Shahar’s Why It’s Ok to Eat Meat (2022) is in Routledge’s series of short books called Why It's OK: The Ethics and Aesthetics of How We Live. Per Bauhn’s Animal Suffering, Human Rights, and the Virtue of Justice (2023) is from Palgrave Pivot, which publishes books falling somewhere between journal articles and monographs. Shahar’s book is worth reading: it’s well-written, raising interesting questions, and offering a coherent defence of meat. Bauhn’s book …

Compact Flexible Heart Rate Monitor Simulations, Jack Ellingson, Dean Arakaki

Electrical Engineering

This project develops and characterizes flexible substrate antennas for heart beat detection through reflection coefficient measurements. Antenna substrate printing and sensor applications are through external collaborations. The project includes curved ground plane and substrate HFSS models to determine reflection coefficient responses to chest expansions.

On Teaching Diversity And Inclusion, Clara Bradbury-Rance

Feminist Pedagogy

In 2020, I was asked to design a module called “Diversity and Inclusion in Practice” for a new online MA. To design a module around this theme was to reckon with a paradox. Scholars such as Sara Ahmed, working across feminist, queer, and critical race studies, have given us theoretical and methodological frameworks not simply for celebrating “diversity” but for exploring this term itself as a function of power. While the use of terms such as diversity and inclusion may be a strategic necessity for social justice work around higher education’s current agenda, this “language of diversity” (Ahmed 2012: 51) …

“I Can’T Learn When I’M Hungry”: Responding To U.S. College Student Basic Needs Insecurity In Pedagogy And Praxis, Jasmine R. Linabary, Rebecca Rodriguez Carey

Feminist Pedagogy

Food insecurity and other basic needs insecurities were pressing concerns for U.S. college students prior to the COVID-19 crisis and are even more so now. These issues disproportionately impact minoritized students, making addressing basic needs an issue of educational equity. As feminist teacher-scholars, we reflect in this essay on what it means to teach in the context of student basic needs insecurities, drawing on our experiences from launching an interdisciplinary initiative dedicated to combatting food insecurity on our campus. In doing so, we seek to catalyze changes within and beyond the classroom to better support students.

An 'intertidal zone' is an area where the ocean meets the land--hidden during the high tide and exposed during the low. Our journal embodies the moment where the tide recedes, revealing stories previously hidden.

Static Vascular Modeling Of Diabetes Progression, Andrea Skattenborg

Master's Theses

Cardiovascular disease is the leading cause of mortality in diabetic patients, and diabetes is one of the main causes of cardiovascular disease. Risk factors for cardiovascular disease result in structural and functional changes in the vascular wall. Arterial stiffness is a prominent structural change observed in the arterial wall that can be measured in clinical settings. The purpose of this thesis was to create a static model of the changes in arterial stiffness seen in diabetes. Elastic tubes with varying wall thicknesses were used to create artificial arteries for this purpose. Compliance (inverse of stiffness) of the arteries was determined …

A Guide For The Everyday Woman Surfer: How Surf Culture's Patriarchy Marginalizes Ocean Lovers, Alexis S. Di Stefano

Women's, Gender and Queer Studies

Humans are naturally drawn to the water by wind and tide. It is a place of solace that we have a desire to know deeply, yet we have kept one another from experiencing it through biases that perpetuate inequality. White-supremacist hegemony has historically kept communities of color from coastlines, women from lineups, and queer communities from participating in surf culture. As more people from all social groups return to the water through surfing in the 20th century, surf culture needs to adapt to become more inclusive. This paper outlines surf culture's historical transition into whiteness and how female beauty standards …

Design And Validation Of A Wearable Smartsole For Continuous Detection Of Abnormal Gait, Karoline M. Wucherer

Master's Theses

Residual gait abnormalities are common following lower limb injury and/or stroke and can have several negative impacts on an individual’s life. Without continuous treatment and follow up, individuals can be prone to chronic pain as abnormal gait may lead to non-physiological loading of the musculoskeletal system. The current industry gold standard for diagnosing abnormal gait requires specialty equipment that is generally only available at designated gait facilities. Due to the inaccessibility and high cost associated with these facilities, a wearable SmartSole device to continuously detect abnormal gait was proposed. A previous iteration of the SmartSole was unable to properly detect …
