Using a critical lens, this content analysis examines the portrayal of Indigenous peoples in select fourth-grade, eighth-grade, and high school social studies and history texts used in Florida …

The Effect Of Political Ideology On The Persuasiveness Of Gainvs. Loss-Framed Climate Change Messages: Testing Competing Hypotheses, Sada Rice

Electronic Theses and Dissertations 2020 - Present

Motivating climate change mitigation is a critical priority. This study examined how message framing (gain vs. loss) interacts with political ideology to influence persuasion. Two competing hypotheses were tested. The Regulatory Focus Fit Hypothesis predicted that liberals (promotion-oriented) would prefer gain-framed messages, while conservatives (prevention-oriented) would prefer loss-framed ones. The Differential Context Hypothesis predicted the opposite: liberals would respond better to loss frames due to alignment with threat-based media narratives, while conservatives would prefer gain frames due to lower reactance and perceived novelty. Messages were also tailored to match individual regulatory focus or the broader political context. Results did not …

The Interaction Of Temporal And Structural Abstractions And Their Influence On Behavior, Ryan Gallagher

Electronic Theses and Dissertations 2020 - Present

The prefrontal cortex (PFC) plays a crucial role in complex behaviors such as planning, decision-making, and adaptive problem-solving, which require integrating new information over time. Research has shown that information related to these behaviors is organized along a hierarchical rostro-caudal abstraction gradient in PFC, with abstract information represented in rostral (anterior) regions and concrete relationships in caudal (posterior) regions. Abstraction involves generalizing information by emphasizing broader concepts over specific details and can be understood more specifically by the context its applied to. However, past studies often confound different forms of abstraction, making it unclear how these different types of abstraction …

Movie Genre Classification Using Script Texts, Michael Roman Cuomo

Electronic Theses and Dissertations 2020 - Present

Genres are used to classify movies so that they can be grouped with others that have similar themes and structures. These classifications are categories created by humans. In the process of creating a movie, a script is often the first creation to write and share ideas about a topic. The script contains large amounts of text that is used to describe the dialog, setting and direction of the film. Although the script contains important information for the film, the amount of text can present a challenge for machine learning algorithms. Often in studies on film classification, if text is used, …

Interleukin-1 Type I Receptor Implicated In Emergence And Severity Of Generalized Tonic-Clonic Seizures In A Transgenic Mouse Model Of Adult-Onset, Progressive Epilepsy:, Tashi Dillon

Electronic Theses and Dissertations 2020 - Present

Interleukin-1 β (IL- 1β) is a proinflammatory cytokine with proconvulsive properties that is elevated in epilepsy. The hippocampal dentate gyrus (DG) buffers hyperexcitability, and deficits in granule neuron gating contribute to epileptogenesis. Excess brain derived neurotrophic factor (BDNF) may drive hyperexcitable circuit assembly, promoting a seizure-producing breakdown of the gating function. We use a transgenic mouse model of forebrain BDNF (TgBDNF) overexpression that exhibit spontaneous generalized tonic/ clonic seizures (GTCSs) at ~3 months, which progress as evidenced by prolonged periods of post-generalized EEG suppression (PGES). This is accompanied by hippocampal hypertrophy and brainstem cell loss. A strain globally lacking IL-1 …

An Evaluation Of Fuel Model Accuracy And Multi-Scale Mitigation Strategies In The Wildland-Urban Interface Of Southern Humboldt County, Julia I. Cavalli

Cal Poly Humboldt theses and projects

Strategic placement of fuel treatments is critical for mitigating wildfire risk and reducing potential structure losses in wildland-urban interface (WUI) communities. As wildfire activity accelerates across the western United States, the need to identify high-impact fuel treatment locations grows increasingly urgent. Concurrently, housing development in the WUI is expanding, intensifying the exposure of homes and infrastructure to wildfire threats. In response, many communities are looking to mitigate the likelihood and severity of losses during wildfire events. The success of these efforts depends, in part, on robust data to support strategic placement of effective treatments that reduce fuel availability.

Highways fragment habitat and can impose barriers to wildlife. Installing wildlife crossing systems creates opportunities for safe animal movement, improved human safety, and reduced property damage. Research identifying key zones of connectivity can aid in providing recommendations for locations of these systems and other tools to improve highway safety. Although elk-vehicle collisions occur broadly across northwestern California, factors associated with these highway crossing zones have not been studied in this region. To address this gap in research, the objective of this study was to evaluate how environmental and structural factors influence the probability of elk (Cervus canadensis) crossing US-101 in …

Snag Failure And Fuel Recovery Following Stand-Replacing Fire In The Klamath Mountains, Joseph R. Nicholas

Cal Poly Humboldt theses and projects

High-severity wildfires can produce extensive patches of standing dead trees (snags), which later contribute to surface fuel loading and present a hazard as they decay and fall. In the Klamath Mountains of northwestern California and southwestern Oregon, recent increases in the occurrence of large stand-replacing wildfires have raised concerns about fuel and vegetation recovery trajectories, the likelihood of future fires, and resulting impacts to local communities. Nevertheless, the post-fire environment may offer opportunities to enhance ecological and community resilience. Estimates of snag failure and fuel loading can support land management planning and risk assessment following wildfire, though such work is …
