The "Upside-Down" River: Trends In Total Nitrogen, Total Phosphorus, And Microcystin Concentration In The Klamath Basin, 2010-2021, Kayla M. Fitzpatrick

Cal Poly Humboldt theses and projects

The Klamath River tends to experience impaired upstream water quality, which improves downstream. Although this consensus is accepted, an updated spatiotemporal analysis of certain water quality parameters has not been conducted since 2017. With four of the Klamath River’s dams slated for removal by the end of 2024, it is critical to have an updated assessment of current water quality conditions from which to compare conditions following dam removal. In this study, total nitrogen (TN), total phosphorus (TP), and microcystin data from 2010-2021 were analyzed to determine concentration trends from Link Dam to the Klamath River Estuary.

Concentrations of TN …

Disney Adult Or Disney Cult?: Observing The Effects And Perceptions Of Transmedia Storytelling Onto Fandom, Sara Spradley

Cal Poly Humboldt theses and projects

Transmedia storytelling is the vehicle for narratives to become immersive to their audience through different modalities. The Walt Disney Company employs this form of storytelling by placing any one of its films in the context of attractions and live-action performances, or vice-versa, creating a convergent culture that will follow these products through every medium. This project views transmedia storytelling used by the Walt Disney Company as the reasoning for the Disney Adults' fandom interest in interacting with Disney products. Through the use of discourse analysis, and digital ethnography I will observe this relationship between the use of transmedia storytelling, fandom …

A Post-Colonial Criticism Of Ernest Callenbach's Ecotopia, Kaitlyn R. O'Dell

Cal Poly Humboldt theses and projects

The representation of Indigenous land-based cosmologies within Ernest Callenbach’s Ecotopia communicates a real perception of our world through the constructed imaginative society within this speculative fiction novel. Ecotopia is an alternative Pacific West Coast society that counters the dominant United States model in its holistic and green approach. This green society relies heavily on Indigenous ideology but lacks actual Indigenous voices or communities within this white idealized society. This research provides an example of the deconstruction of this popular novel to its main problematic components, establishing why the use of Indigenous beliefs and values can cause negative implications to the …

The Persistent Voice Of The Colonizer: Troubling A Mascot’S Settler-Colonial Past, Linda J. Kuckuk

Cal Poly Humboldt theses and projects

The legacy of settler-colonialism permeates American culture. Remnants of westward expansion remain in our societal divides, political differences, environmental inequities and economic inequalities. Conversations about decolonization, gentrification, and other ongoing practices that precipitate and uphold colonialism are notably found in literature, art, social structures, icons and symbols. Mascots that rely on stereotypes or caricatures can contribute to negative perceptions and reinforce discriminatory attitudes, making it necessary to reevaluate and change representational practices. In this analysis I apply historical, textual, and visual methods to explore Cal Poly Humboldt’s mascot Lucky Logger and identify how this character is a “persistent voice” by …

Analyzing Science Classroom Design Ideas Of High School Students: Variations Amongst Lgbt-Identifying Students, Abraham A. Lewis

Cal Poly Humboldt theses and projects

The physical design of science classrooms is a leading factor in determining the uses of the classroom and the comfort and engagement of students in the classroom, and if a science classroom is designed with only the majority of students or the average student in mind, the classroom design may have a negative impact on the comfort, engagement, and perceptions of minority groups of students, such as queer students. The purpose of this research is to identify how a science classroom’s design impacts the perceptions, engagement, and comfort of queer students, and to use student suggestions to identify science classroom …

Simulated Effects Of Postpartum Depression On Maternal-Infant Bonding: Mediated By Reward-Related Responses To Infant Facial Cuteness, Caitlin Harp

Cal Poly Humboldt theses and projects

Infant cuteness (facial cuteness in particular) is linked to evolutionary adaptations to motivate caretaking and protective behaviors (Kringelbach et al., 2008). Previous neuroimaging work has demonstrated that infant cuteness activates reward-related regions in the brain (Glocker et al., 2009) and behavioral work suggests that the reward value of cuteness is linked to maternal tendencies (Hahn et al., 2015). It is estimated that 15% of new mothers experience postpartum depression (PPD) (Wisner et al., 2013), which impacts the mesolimbic system and is linked to anhedonia (i.e., reduced ability to experience pleasure). Based on the above literature, this study used a simulated …

“Bad At Reading”: Narratives Of Boys With Negative Reading Self-Concept, Aimee Talmadge

Cal Poly Humboldt theses and projects

There is a clear and consistent gender gap between students who view themselves as readers and those who do not (Love & Hamston, 2003). Overwhelmingly, young men report a lower self-perception of their ability and interest in reading and literacy, and this in turn impacts their growth and motivation in literacy learning. Through this study, I interviewed six students, specifically male high school students who self-identified as bad at reading or disliking reading. Through one-on-one interviews and focus groups, I explored how they viewed themselves as “non-readers” and why their reading self-perception is negative. The findings show how the lack …

Evaluating The Trojan Y Chromosome Strategy For The Removal Of Invasive Sacramento Pikeminnow From The Eel River, Ca, Alexander W. Juan

Cal Poly Humboldt theses and projects

The recent introduction and spread of Sacramento Pikeminnow (Ptychocheilus grandis) in Northern California’s Eel River Basin represents a significant threat and impediment to the recovery of several threatened native fish species. This study was undertaken to evaluate the Trojan Y Chromosome Strategy (TYC) for the extirpation of pikeminnow from the basin. TYC is a genetic biocontrol method that relies on the production and stocking of fish with YY sex chromosomes, which may be phenotypically male (YY male) or female (YY female). These YY fish produce all-male offspring when mating with their wild conspecifics and TYC can lead to …

The Potential For Competency-Based Teaching Methodologies To Increase Intervention Procedural Fidelity And Reduce Self-Reported Verbal Behavior Associated With Turnover In Behavior Technicians, Dean I. Shearer

Cal Poly Humboldt theses and projects

Within the field of applied behavior analysis, behavior technicians (staff who are supervised by behavioral analysists and provide direct services to clients) experience relatively high rates of turnover. It is possible that improved teaching methodologies which boost the efficacy of these staff may help reduce this turnover by reducing verbal behavior associated with burnout and improve perceptions of training and supervision. We compared intervention procedural fidelity and staff ratings of burnout, supervision, and satisfaction with training following a didactic training, a behavioral skills training, and after a month-long follow up. We found that when mastery criteria were set sufficiently high …

K-Perm: Personalized Response Generation Using Dynamic Knowledge Retrieval And Persona-Adaptive Queries, Kanak Raj, Kaushik Roy, Vamshi Bonagiri, Priyanshul Govil, Krishnaprasad Thirunarayan, Raxit Goswami, Manas Gaur

Publications

Personalizing conversational agents can enhance the quality of conversations and increase user engagement. However, they often lack external knowledge to tend to a user’s persona appropriately. This is particularly crucial for practical applications like mental health support, nutrition planning, culturally sensitive conversations, or reducing toxic behavior in conversational agents. To enhance the relevance and comprehensiveness of personalized responses, we propose using a two-step approach that involves (1) selectively integrating user personas and (2) contextualizing the response with supplementing information from a background knowledge source. We develop K-PERM (Knowledge-guided PErsonalization with Reward Modulation), a dynamic conversational agent that combines these elements. …

L∞ Bounds For Transient Growth In Repetitive And Iterative Learning Control Systems, Douglas A. Bristow, John R. Singler

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This paper revisits the problem of large transient growth in Iterative Learning Control (ILC) and Repetitive Process Control (RPC) systems. In ILC and RPC problems a process is repeated iteratively, with new control calculations occurring in between each iteration. Large transient growth refers to the propensity of some control algorithms to grow error exponentially before eventually converging. While robust monotonic convergence algorithms (in which monotonic convergence is guaranteed usually in exchange for a small loss in performance) have largely eliminated the concern for large transient growth in ILC, similar results cannot always be obtained in RPC. The emergence of additive …
