Integrating Multi-Method Monitoring To Characterize Seasonal Habitat Use Of Green Sturgeon (Acipenser Medirostris) In Humboldt County, California, Olivia S. Boeberitz

Cal Poly Humboldt theses and projects

Green sturgeon (Acipenser medirostris) are a long-lived, anadromous, iteroparous species that spawns in large West Coast North American rivers but ranges widely in the coastal ocean. For coastal California Native American Tribes, green sturgeon are a vital part of their cultural heritage and traditions, and central to their food security. Two genetically distinct population segments (DPSs) of green sturgeon are recognized in the United States, Canada, and Mexico; the southern DPS is listed as “threatened” under the Endangered Species Act and the northern DPS is considered of “conservation concern.” Although green sturgeon are known to use large estuaries …

Depth And Soil Physical Context Govern Soil Organic Carbon, While Woody Cover Moderates Native Vegetation Relationships In California Rangelands, Dabid Zuniga Garcia

Cal Poly Humboldt theses and projects

Soil organic carbon (SOC) is central to soil function and an important component of climate mitigation in rangeland ecosystems, but the controls on SOC across California’s working rangelands remain understudied. Using data from Point Blue Conservation Science’s Rangeland Monitoring Network, this study evaluated how soil properties, vegetation structure, and recent climate relate to SOC concentration at depths of 0–10 cm and 10–40 cm across 145 ranches spanning four California regions. Linear mixed-effects models showed that SOC was consistently higher in topsoil than subsoil and highest in coastal sites relative to interior valleys. Bulk density was the strongest negative predictor of …

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 …

Queering Poetry Workshops, Dobby Morse

Cal Poly Humboldt theses and projects

To what extent do participants report that a poetry workshop builds connections between poets and strengthen their confidence in writing? What do participants want or expect from a poetry workshop?

Through this project I hope to attend and host poetry workshops with an emphasis on the queer community. I will collaborate with campus and community organizations like Queer Humboldt and other organizations that are interested in exploring queer experiences through writing, connection, and meditation. This project will serve as a how-to guide for those seeking to conduct their own workshops.

Evidence Of Personality And Movement Syndromes In A Mobile Predator: How Individual Hunting Strategy Shapes Ecosystem Service Potential By Barn Owls (Tyto Furcata) In An Agroecosystem, Lauren M. Jackson

Cal Poly Humboldt theses and projects

Animal-mediated ecosystem services are delivered through the behavior of individuals, yet most studies evaluate service-providing species at the population level. We tested whether individual variation in plumage, behavior, and movement predicted hunting behavior and vineyard habitat use by adult male American barn owls (Tyto furcata) nesting in winegrape vineyards in Lodi, California, USA. We fitted GPS-accelerometer tags to 42 breeding males, quantified breast-plumage traits, measured neophobia using repeated novel object tests, and derived nightly movement metrics from GPS tracks and hidden Markov model-classified hunting locations. Several behavioral traits were repeatable, but movement traits showed the clearest repeatable individual …

Contribution Of Lagoon-Rearing Juvenile Chinook Salmon (Oncorhynchus Tshawytscha) To The Adult Spawning Population In The Mattole River, Emma Held

Cal Poly Humboldt theses and projects

Bar-built estuaries are rivermouth confluences characterized by periods of disconnection between the river and the ocean due to a sandbar that builds across the mouth. Sandbar timing characteristics vary between years and between systems, but when closed, a lake-like lagoon forms in the estuary footprint. The Mattole River has a bar-built estuary that forms in late spring or early summer, often overlapping with juvenile Chinook salmon outmigration. Juveniles that do not leave the river before the bar closes must remain in the lagoon until the mouth opens in fall. The purpose of this thesis was to understand if lagoon-rearing is …

Symmetry In Affiliative Interactions Of North American River Otters (Lontra Canadensis) In A Northern California Estuary, Charlotte E. Norman

Cal Poly Humboldt theses and projects

Patterns of participation in affiliative behaviors may reflect underlying social dynamics. Two affiliative behaviors, allogrooming and social play, were assessed for their symmetry, or relative participation of participants, in a wild group of North American river otters. Behavioral observations were conducted over five months at the Little River estuary in northern California using video recordings and all-occurrence sampling. Observations included all-adult groups, a family group consisting of a breeding female and two pups, and an extended family group with one or two helpers, indicative of cooperative breeding. Individuals engaged in allogrooming and social play were classified by their group membership, …

A Narrative Analysis Of Equity-Focused Cs Educators: A Multiple Case Illustration, Aleata Hubbard, Jen Tsan

Journal of Computer Science Integration

Background and Context. Equity-focused CS teaching is often prescribed as a solution for addressing disparities in K–12 CS participation and disengaging student experiences. However, adopting such an orientation can be challenging as it pushes educators to shift their teaching beliefs, identity, and practices. Objective. This study examines how the personal and professional experiences of four high school CS teachers influenced their paths to becoming equity-oriented practitioners. We illustrate variation in these developmental trajectories and advance theory building around equity-focused CS teacher identity development. Method. We utilized a multiple-case narrative inquiry approach, collecting data through in-depth, semi-structured interviews that included a …

Humanizing The Base Of The Pyramid: Exploring The Influence Of Resource (Dis)Advantages On Value Creation, Ted London, Lisa Jones Christensen, Tyson Mackey, Alison Mackey, Heather Esper, Andrew Grogan-Kaylor

Faculty Publications

Base of the pyramid (BoP) scholarship emphasizes the potential for enterprises to generate profits by enhancing the wellbeing of the impoverished, often by selling socially-beneficial products (SBPs). Yet, many such BoP enterprises have experienced mixed results. We argue that this may stem from insufficient attention to how BoP consumers value SBPs and other products. We frame SBPs as a type of human capital investment and thus use human capital theory to study how the consumption of SBPs does or does not create value for consumers. Specifically, we use a novel data set from rural India to measure value creation in …

Retrenchment, Segregation, And Public Education: A Five-Year Analysis Of State Exclusionary School Discipline Legislation, Thalia Gonzalez, Will Martel

Faculty Scholarship

Notwithstanding the decision in Brown v. Board of Education formally ending educational segregation and more than two decades of state reform, the legislative landscape protecting minoritized children from the structural violence of exclusionary school discipline has dramatically shifted in less than five years. From the passage of state “Teacher’s Bills of Rights” to mandatory expulsions, rescissions of prior protections, and new categories of removal, a retrenchment of anti-inclusion legislation—and its corollary, educational carcerality— has occurred. While studies of other forms of legislative retrenchment in K–12 public schools, such as anti-Critical Race Theory and Don’t Say Gay laws, literacy bans, and …

Open Secrets, Robin C. Feldman, Vaughn Goehrig

Faculty Scholarship

Patents and trade secrets were never intended to meet, but in the world of biologic drugs, they've become as thick as thieves. Patent law's disclosure requirement has demanded far too little of biologics manufacturers-allowing them to keep vital manufacturing details under trade secret lock and key. This intellectual property patchwork has been devastating for drug affordability: Because the most critical manufacturing information remains hidden, makers of follow-on biologics (called biosimilars) are often stuck reinventing the wheel, even after the original patents have expired.

This Article makes two principal contributions to illuminating this problem. First, it presents, for the first time …

Prevention Beyond Deterrence, Benjamin A. Barsky

Faculty Scholarship

This Article reconceptualizes preventive justice—the public safety paradigm that seeks to prevent harm before it occurs. Scholars have long documented how cities have advanced this paradigm through largely punitive measures, notably variants of broken windows policing, which posit that aggressive misdemeanor enforcement deters more serious crime. Yet in the aftermath of the 2020 George Floyd protests, and as underscored recently in City of Grants Pass v. Johnson, these measures have faced a legitimacy crisis—prompting calls for nonpunitive responses to nonviolent incidents.

This Article establishes a preventive justice approach that advances health and safety without emphasizing crime deterrence. It draws on …

Elephant Economics And Agrarian Transitions: Conditions For Benefiting From Elephant Tourism Market In An Upland Karen (Paganyaw) Village, Xiaoyun Neo, Aswin Baharuddin, Nur Fadilah Sunardi

Forest and Society

In rural, upland northern Thailand, Indigenous Karen (Paganyaw) communities have long practiced diversified subsistence cultivation and forest-based livelihoods. Yet state conservation policies and tourism-led development are reshaping these agrarian systems and livelihoods. This paper explores how one Karen (Paganyaw) community in Chiang Mai province reconfigures its livelihood strategies amid the decline of swidden cultivation and the rise of elephant tourism as a new rural economy. Beyond subsistence cultivation, villagers are seeking to diversify their households and personal income by participating in this new economic sector. We argue that the transition out of small-scale agriculture into tourism is not a neutral …

The Disenchanted Grove: Postcolonial Modernity And The Decline Of Ri’I Bamboo Governance In Flores, Indonesia, Handoyo Handoyo, Puji Hastuti, Lukas Rumboko Wibowo, Budiyanto Dwi Prasetyo, Surati Surati, Kresno Agus Hendarto, Lila Juniyanti, Dewi Ratna Kurnia Sari, Desmiwati Desmiwati, Sanusi Sanusi, Ane Dwi Septina, Ramawati Ramawati

Forest and Society

This article explores the erosion of ri’i, a traditional ecological governance system practiced by the Ngadha people in Flores, Indonesia, in the face of modernization and postcolonial development. Based on long-term ethnographic fieldwork and interviews with cultural elders, ritual practitioners, and local authorities, the study documents how ri’i—a ritual-based regulatory system for bamboo resource management—has been progressively dismantled through the combined pressures of technocratic governance, land commodification, and shifts toward individualism. Empirically, the main drivers identified are state land certification (including Sertifikat Hak Milik, SHM) and village modernization campaigns, which reconfigure communal tenure and everyday governance practices. Once embedded …

Memoryart: Enhancing Llms Via Multi-Memory Models With Adaptive Resonance Theory For Healthcare Agents, Renke Dai, Hebin Hu, Jiahui Zhang, Yilin Kang, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

Though promising in healthcare consultation applications, large language models (LLMs) face critical limitations in retaining and utilizing long-term memory across multiturn interactions. In particular, existing memory enhancing paradigms are constrained by limited context windows and embedding-based retrieval, often failing to maintain task relevance and still suffering from memory prototype collapse in multi-turn healthcare consultation. To address these challenges, we propose a cognitively-inspired memory framework named MemoryART, which is grounded in Adaptive Resonance Theory (ART)—a cognitive and learning theory of how humans and animals adapt to dynamic environments. MemoryART employs three memory modules—working memory, episodic memory, and semantic memory to support …

The Right To Seek Joy, Tyler Rose Clemons

Faculty Publications

Within the past three years, roughly half of American states have restricted access to gender-affirming medical treatment for children. In this article, I argue that these bans violate transgender children’s right to liberty guaranteed by the Fourteenth Amendment’s Due Process Clause. I do so by excavating the Framers’ understanding of liberty as the right to seek joy. Rooted in the philosophies of John Locke and Epicurus, the Framers understood liberty as the right to make important life decisions according to one’s subjective preferences without undue interference from the government. Based on this understanding, I develop a new framework for substantive …

Does Subarachnoid Dexmedetomidine Decrease The Incidence Of Shivering And Postoperative Nausea And Vomiting In Cesarean Section?A Prospective Randomized Controlled Trial, Ali El-Sayed Khayal, Amr Abdellatif

Journal of Medicine in Scientific Research

Background: Spinal anesthesia during cesarean sections is associated with a number of common problems, including postoperative nausea and vomiting (PONV), which can make the mother feel uneasy and negatively impact the perioperative results. The neuraxial adjuvant dexmedetomidine has shown promise since it is a very selective α₂- adrenergic receptor agonist that can improve spinal anesthesia and also provide extra sedative and anti-shivering effects. Objective:To evaluate the effect of adding 5μg intrathecal dexmedetomidine to hyperbaric bupivacaine on the incidence of shivering and PONV during elective cesarean section. Patients and Methods: Elective caesarean sections under spinal anesthesia were elective for 100 healthy …

Study Of Fire Regimes In Southwestern Australia Using Geospatial Techniques, Ana Do Carmo Carvalho

Theses: Doctorates and Masters

The Northern Jarrah Forest in Southwestern Australia (SWA), part of a global biodiversity hotspot, is home to fire-sensitive tree species such as marri (Corymbia calophylla) and jarrah (Eucalyptus marginata). As climate change intensifies drought and extreme fire events, understanding the drivers of fire severity is increasingly critical. This thesis analyses fire regimes within the Mundaring drinking water catchment to better understand the spatiotemporal complexity of fire severity in relation to fire history and environmental factors.

The thesis commences with a review of three Fire History Databases (FHDs) used in SWA, highlighting significant inconsistencies and data gaps across time and space. …

Prairie Plant Detectives: Place-Based Learning Plan For The Msum Regional Science Center, Sydney Ganschow

OER Materials

In this lesson, students explore the prairie at the MSUM Regional Science Center to learn how plants survive. Students take a closer look at different plants and draw or write about what they notice. They compare plants, share their ideas, and learn how features like deep roots and narrow leaves can help plants survive. Students also discuss why prairie plants are important to animals and pollinators. At the end of the lesson, they use evidence from their observations to explain how a plant’s features help it survive. Learning outside gives students a chance to connect what they learn in science …

21st Century Perspective On The Changing Pattern Of Nerve Injuries From Gunshot Wounds In The U.S., Thomas A. Decoster

Western Journal of Orthopaedics

Gunshot wounds (GSWs) with nerve injuries in the 21st century differ significantly from those reported in the 20th century. The vast majority are now low-velocity civilian injuries, in contrast to high-velocity military injuries previously reported. The rate of nerve injury in civilian GSWs is approximately 5%, compared with the 30% reported in military cohorts. However, the most common pattern of nerve injury in the current civilian population is neurotmesis and partial neurotmesis, in contrast to the majority axonotmesis of the military cohorts. In the 20th century, treatment generally consisted of watchful waiting for signs of spontaneous recovery over three months …

Peripheral Nerve Repair And Reconstruction: Current Techniques, Adjuncts, And Emerging Therapies, Niklaus Skipp, Lana Dokic, Christina Wassef, Jazzlyn Gonzalez, Ana Love, Heather Mercer, Deana Mercer

Western Journal of Orthopaedics

Peripheral nerve injuries require reconstruction when direct, tension-free repair is not possible. A range of reconstructive strategies are used to restore continuity and promote axonal regeneration, including graft-based reconstruction, nerve transfers, conduit-based repair, supercharged end-to-side augmentation, and emerging regenerative therapies. Autologous interfascicular nerve grafts and vascularized grafts remain established techniques, whereas processed nerve allografts provide a donor-sparing alternative. Nerve transfers are increasingly used for proximal injuries with long regeneration distances, and conduits are an option for gaps shorter than 5 mm. Nerve-wrapping techniques are used to reduce perineural scarring and preserve gliding in complex or revision cases. Emerging adjunctive therapies, …

Play-Based Learning In Private International Preschools In Cairo: Teachers' Perspectives, Kesha L. Stovall

Theses and Dissertations

This thesis explores how play-based learning is practiced and contextualized in private, international preschools in Cairo, Egypt through the perspective of teachers. It calls upon both historical and contemporary theories of play and play pedagogies ranging from the times of Plato and Al-Farabi to the 21st century with Montessori and Dewey. Using a contemporary theory of play presented by Stuart Lester and Wendy Russell as a guiding framework, it examines how play and play-based learning are implemented, shaped and even challenged in a Cairene context. These contexts include sociocultural factors such as parents’ expectations and aspirations, institutional barriers, teacher development …

Implementing Bespoke Assistive Technologies: An Approach For Successful Introduction And Use Of Assistive Technology In Supported Living For Individuals With Intellectual Disabilities., Benjamin Morris

School of Health Professions Theses

Background: While the potential of assistive technologies for improving the lives of individuals with intellectual disabilities is well documented, successful implementation of these technologies is a complex challenge. Adoption-and-use-models of assistive technology are a key method to guide such adoption technology, however no specific model for supported living of those with intellectual-disability existed prior to this research. The research aimed to investigate how bespoke digital assistive technologies can be implemented in the supported living environment for people with intellectual disabilities. Three primary outputs were produced in order to address the research question. 1. A theoretical model that explains the barriers …

Antigypsyism: Foundations Of An Ideology Of Hatred Towards Roma, Fernando Ruiz Molina, Zoë James

School of Law, Humanities and Social Sciences

Roma communities represent the largest ethnic minority in Europe (European Parliamentary Research Service, 2021), dating their presence from the fourteenth century onwards (Council of Europe [CoE], 2012a; CoE n.d.-a; End, 2012).¹Accord-ing to the Council of Europe, it is estimated that the population of Roma citizens living currently in Europe is around 10 to 12 million (CoE, 2012a). Despite their long-standing presence in European countries, Roma are hated within their own countries. From Eastern to Western Europe, animosity towards Roma centres on public acceptance of stereotypes of their criminality and lifestyles, leading to this minority group experiencing the most bias-motivated crime …

Off-Label Abuse: The Prosecution Of Individuals For Pesticide Crimes Under The Federal Insecticide, Fungicide, And Rodenticide Act, Joshua Ozymy, Melissa Jarrell Ozymy

Natural Resources Journal

When individuals commit pesticide crimes involving significant harm or culpable conduct, they may be prosecuted for criminal violations of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), but we have little knowledge of how individual offenders have been prosecuted historically for such crimes. Using content analysis of 2,728 environmental crime prosecutions resulting from U.S. EPA criminal investigations, 1983 to 2021, we select all cases of individuals prosecuted under FIFRA for our analysis. We find that 100 cases were adjudicated, resulting in 135 years of probation, 75 years of incarceration, and $4.2 million in monetary penalties assessed at sentencing. Of those …

Assessment Of Simulation Software Used For Cubesat Gnc Verification And Validation By University Research Teams, Alexander Taiyo Newett

Masters Theses

As the growth in university satellite teams continues, along with the greater trend in the small satellite market, the need for a guidance, navigation, and control verification and validation pipeline suitable for these young and inexperienced teams becomes evident. Much of the mathematical theory and software implementation of GNC concepts are large hurdles for teams largely composed of undergraduate students.

Many software packages exist that can help these teams achieve GNC verification and validation. If the learning curves of these software packages can be overcome, new satellite teams have the opportunity to better build and test GNC algorithms that are …

Aura-Visionpose: Creating Datasets For Vision-Based Pose Estimation, Mohanad Alameer

Masters Theses

"Spacecraft rendezvous is an integral part of many orbital missions, including active space debris removal (ADR) and in-orbit servicing, assembly, and manufacturing (ISAM). Traditionally, rendezvous missions rely mainly on manual ground-based control to perform rendezvous and docking. While this can be effective on an individual basis, it becomes less practical at scale. Autonomous vision-based methods can reduce reliance on human control, and may improve scalability, response time, and reduce the possibility of human error for both ADR and ISAM. This work lays the necessary groundwork for developing a machine learning (ML) model for autonomous rendezvous by creating a labeled image …
