Home Range, Habitat Use, And Fall Migration Of Lewis’S Woodpeckers In The Eastern Cascade Range, Oregon, Cameron Piper

Cal Poly Humboldt theses and projects

Lewis’s woodpecker (Melanerpes lewis), a burn specialist, is experiencing range-wide population declines despite increasing fire activity in the western U.S. The White River Wildlife Area in Oregon hosts the state's only year-round population, raising questions about their breeding, habitat use, and migration. In summer 2024, we tracked nine woodpeckers using telemetry to estimate home range size and overlap. Full home ranges averaged 428 ha, with 66 ha core areas, and showed evidence of growing after nesting. Home ranges overlapped extensively (Full: 91 ± 13%; Core: 63 ± 29%), though individuals had distinct areas of intense use. Males had …

Can We Help Coast Redwood Adapt To Climate Change? A Provenance Study On Genetic Variation And Climate Transfer Distance, Aidan J. Murphy

Cal Poly Humboldt theses and projects

The climate is changing more rapidly than many species can adapt or migrate. Coast redwood (Sequoia sempervirens) is a unique, long-lived conifer and remains California’s most valuable and economically important timber species. The species is threatened in its natural range due to anthropogenic climate change and human activity. Redwood favors asexual reproduction which restricts its ability to migrate naturally. The consequences of asexual reproduction when faced with a rapidly changing climate may make some form of assisted migration necessary for long-lived organisms like redwood.

This study evaluates drivers of variation in redwood growth and the influence of climate …

The Menstrual Cycle, Dual-Hormone Hypothesis, And Competition: Implications For Athletic Performance, Camille Burns

Cal Poly Humboldt theses and projects

Female athletes perceive that the fluctuating hormones of the menstrual cycle affect their performance. However, research on objective performance is inconclusive, partly due to a lack of studies conducted in real-world competitive contexts. Testosterone is often seen to be elevated near ovulation and is related to social competitiveness. Under the dual-hormone hypothesis, testosterone only predicts competitive behavior when cortisol is low. The current study had two goals: (1) to test whether the dual-hormone hypothesis applied to competitive drive and objective athletic performance, and (2) to examine whether competitiveness and the intensity of one’s response to competition varied across the menstrual …

Effects Of Teacher Reinforcements On Student Outcomes In Adapted Physical Education: A Meta-Analysis, Yaxeny Moreno

Reinforcement strategies, such as positive reinforcement/feedback, token economies, verbal praise, tangible rewards, and additional strategies are essential for fostering engagement and skill development. Literature has provided evidence and results to highlight the importance of applying evidence-based reinforcement strategies to which support the behavioral, social, and physical development of students in both Physical Education and Adapted P.E. settings. The purpose of this study was to review and analyze existing literature …

Community Assembly Across Environmental Gradients: Contrasting Patterns Of Funtional Convergence And Divergence In California Coastal Grasslands, Ernesto Chavez- Velasco

Cal Poly Humboldt theses and projects

Elucidating how plant community assembly processes interact across spatial scales to shape ecosystem function remains a central challenge in ecology. These processes are often hierarchical, with broad scale environmental filters constraining the composition of local communities. I investigated these hierarchical processes across three California coastal grassland sites spanning a ~1000 km gradient. At these sites, I measured community composition, standing biomass, four functional traits (plant height, specific leaf area, leaf dry matter content, and leaf lobedness), and estimated species’ environmental niches. To identify assembly mechanisms, I used null models to assess functional convergence or divergence and scaled these patterns with …

Lineation To Liberation: The Transformative Power Of Poetic Rhetoric, Amber Rae Alvarez

Cal Poly Humboldt theses and projects

This project explores the transformative power of poetic rhetoric and examines how poetry as a form of expressive art serves as a means of reclamation in the aftermath of encounters with the American criminal justice system. I contend that poetry provides a space where folks can reimagine (and reclaim) their identities, asserting their agency in empowering and authentic ways. Taking a Cultural Studies and Critical Prison Studies informed approach, this project engages the concept of lineation to liberation to conduct a close reading analysis of artist (Reginald) Dwayne Betts’ poetry. Betts’ work not only provides a powerful example of how …

Impacts Of Autistic Traits On Student Evaluations Of Professors, Matias Solorzano

Cal Poly Humboldt theses and projects

Instructor evaluations are critical to the tenure process in academia, but are biased against autistic individuals in academic settings. This study addresses how instructor evaluations are impacted by the gender of the professor, whether the instructor discloses their autism identity, and the gender of the student evaluator in a 2 Professor Gender (Male or Female) x 2 Autism Identity (Disclosed v. Not Disclosed) x 2 Student Gender (Male or Female) between-subjects design. It was hypothesized that male professors will be rated higher than female professors, that disclosing one’s autism identity leads to higher evaluations than non disclosure, and that female …

An Analysis Of Uv Disinfection Of Municipal Wastewater Following Natural Treatment Systems, Jonathan Andrew Kirchubel

Cal Poly Humboldt theses and projects

On January 30, 2024, the City of Arcata replaced chlorine with ultraviolet (UV) irradiation as its disinfection method for treating its wastewater prior to discharging to Humboldt Bay. The Arcata wastewater treatment facility (AWTF) utilizes natural treatment systems for treating its secondary effluent, which can provide issues for UV disinfection through variance in turbidity, total suspended solids (TSS), pH, humic acids, and color. This project aimed to identify whether the water quality characteristics of natural treatment systems in the AWTF would impact UV disinfection of municipal wastewater.

Thirty-one sampling periods occurred between June 8, 2024, and March 1, 2025, recording …

A comprehensive literature search spanning from 1979 to 2024 across six databases identified 18 studies meeting inclusion criteria, involving 140 participants aged 3–22 with diverse physical and cognitive disabilities. Reinforcement strategies evaluated included token economies, verbal praise, tangible rewards, and alternative techniques such as video modeling and peer-mediated interventions. Outcomes measured were categorized into affective states, behavioral improvements, and cognitive gains. Results showed mixed effectiveness across studies: while 7 of the 18 studies reported significant improvements in …

Evaluating The Effects Of Memory Aids On Conversational Behaviors In Older Adults With Cognitive Decline And Their Caregivers, Sarah B. Romero Pavon

Cal Poly Humboldt theses and projects

As the baby boomer generation (individuals born between 1946 and 1964) continues to age into late adulthood, the need for resources and care related to aging is in high demand. Age-related neurocognitive decline (NCD) is broadly characterized by a gradual decrease in one’s ability to think, remember, and reason. Loss of speech and coherent conversation is a common challenge for older adults with neurocognitive decline, often marked by an increase in nonspecific pronoun use, frequent and sudden shifts in topic, and repetition, which can lead to a decrease in activity engagement, less social interaction with peers, and social isolation. Memory …

Faith, Freedom, And Friction: The Intersection Of Intimate Citizenship And Religion In Central And Eastern Europe, Evelina Juchnevičiūtė Ms.

Occasional Papers on Religion in Eastern Europe

Intimate citizenship, a dimension of citizenship that emerged from the second wave of feminism, refers to rights related to intimate life, including women’s reproductive rights, same-sex relationships, and other related rights. In Central and Eastern Europe, these rights have been shown to come into conflict with the region’s deeply embedded religious values that have historically shaped societal norms around reproduction, gender, and sexuality. The present study employed a mixed-method systematic literature review, combining bibliometric and thematic analyses, to examine academic literature on the intersection of intimate citizenship and religion in Central and Eastern Europe. The review covered the period 1990-2024 …

Digital Orthodoxy And Political Populism In Eastern Europe: How Orthodox Media Facilitate Political Mobilization, Dmytro Garaschuk, Oleh Sokolovskyi

Occasional Papers on Religion in Eastern Europe

This article examines the intersection of Orthodox digital media and political populism in Eastern Europe, focusing on how religious institutions utilize digital platforms to facilitate political mobilization, reinforce nationalistic narratives, and undermine democratic institutions. Drawing on a comparative analysis of six countries–Russia, Ukraine, Romania, Serbia, Georgia, and Montenegro–the study identifies a shared ideological matrix that fuses populist rhetoric with theological motifs. The research highlights the strategic use of digital media by Orthodox actors to construct moral binaries, sacralize political resistance, and disseminate disinformation framed in religious language. Particular attention is given to the role of the Russian Orthodox Church and …

The Effects Of Salinity On The Cutaneous Microbiome And Pathogen Infection On The Pacific Tree Frog (Pseudacris Regilla) In Monterey Bay, California, Usa, Hannah Eunhae Kim

EWU Masters Thesis Collection

Global climate change and infectious diseases are considered a leading cause of amphibian population declines worldwide. Changes in precipitation and salinity have altered watershed systems and microbial communities, reducing habitat availability and physiological performances for amphibian survival. The salt refuge hypothesis, however, is a proposed explanation that higher saline environments may reduce susceptibility to pathogens such as Batrachochytrium dendrobatidis (Bd). The Moro Cojo Slough State Marine Reserve (MCSSMR) (California, USA) is known as an abundant breeding ground for endangered/threatened amphibian species. To test and expand the salt refuge hypothesis, I evaluated Bd prevalence and intensity and the cutaneous microbiome of …

Time And Flesh: Exploring The Embodied Experiences Of Black Mothers, Amber Tucker

Social and Cultural Sciences Faculty Research and Publications

Drawing on Black feminist theories of intersectionality and concepts of temporality and embodiment, this study centers Black girlhood to understand Black girls embodied journeys of “becoming” Black women. Findings revealed that: (a) Black girls often have complicated histories that lead to constrained and liberatory choices in adulthood and motherhood; (b) becoming a Black woman involves continual adaptations to temporal and historical contexts; and (c) Black motherhood is a contested space, deeply shaped by remembering Black girlhood and navigating maternal responses to legacies of harm. This study highlights the challenges and strengths in the transitory states of Black womanhood.

Towards The Abolition Of The Immigration Detention Of Children In The United States, Lauren E. Bartlett

All Faculty Scholarship

For over a decade, international human rights mechanisms have been calling for the prohibition of the detention of children based solely on immigration status. Human rights experts agree that the detention of children for immigration purposes is never in the best interests of the child, it leads to long-term harm, and it is a clear human rights violation. Until recently, the United States has detained hundreds of thousands of migrant children in cages each year and we have still not outlawed the inhumane practice. This article argues that engaging with international human rights mechanisms on this topic, including during the …

The Value Of A Statistical Life: From Skin In The Game To Vision Zero, Michael C. Duff

All Faculty Scholarship

This essay discusses justice issues surrounding occupational safety and health and assesses the ethical legitimacy—the justice—of regulatory cost benefit analysis when the costs in question involve the risks and realization of workplace injury and fatalities. The current “value of a statistical life” for legal-regulatory purposes is 13.1 million dollars. While economists are careful to say that this figure does not “really” represent an attempt to value any particular life, the purpose of even calculating the number is to provide an “aggregated” statistical justification for saying “no” to rules requiring safer work. This seems acceptable until you, or someone you love, …

Pharmaceutical-Telehealth Confederacies, Michael S. Sinha

All Faculty Scholarship

Access to prescription pharmaceuticals has historically been controlled by a physician’s pen. As a result, pharmaceutical companies spend billions of dollars on advertising and promotion to mitigate this barrier: first and primarily, to physicians and other prescribers, and more recently, to the general public through direct-to-consumer advertising. The success of these promotional efforts can be seen in greater prescribing of costly brand-name medicines, even in settings where lower-priced generic alternatives exist. Brand-name prescriptions now make up only 10% of all prescriptions written yet account for 87% of drug spending. Despite these substantial returns on investment, companies continue to seek opportunities …

An Indecent Exposure Of The Rules Of Legal Ethics, Lauren E. Bartlett

All Faculty Scholarship

Thousands of attorneys experience rape and sexual assault by clients, as well as indecent exposure, public masturbation, unwanted touching, verbal threats, and stalking. These incidents are not often publicly reported, but client sexual violence against attorneys is not uncommon. The ethical rules currently fail to account for an attorney who has experienced client sexual violence, whether to allow for termination of representation or to mitigate future harm to other lawyers. While the ethical rules are usually thought of as neutral, this Article critically examines the gender stereotypes and structures of oppression corseting the rules. Relying on a fifty-state survey of …

Dirty Water, Breanna Booker, Michael S. Sinha

All Faculty Scholarship

Plastics are taking over. Every day, humans are exposed to plastic pollutants in a variety of ways. From the water we use to water crops in the field, to the water in our taps, to the liquids we drink from plastic containers, it can be found virtually anywhere you look. Not only is it everywhere in the environment, but it is also within us. It builds up in our bodies. Plastics have become a major public health concern; researchers estimate that the total healthcare cost related to plastic chemicals may be as much as $250 billion.[1]

Semi-Supervised Multimodal Multi-Instance Learning For Aortic Stenosis Diagnosis, Zhe Huang, Xiaowei Yu, Benjamin S. Wessler, Michael C. Hughes

Computer Science Faculty Research & Creative Works

Automated interpretation of ultrasound imaging of the heart (echocardiograms) could improve the detection and treatment of aortic stenosis (AS), a deadly heart disease. However, existing deep learning pipelines for assessing AS from echocardiograms have two key limitations. First, most methods rely on limited 2D cineloops, thereby ignoring widely available Spectral Doppler imaging that contains important complementary information about pressure gradients and blood flow abnormalities associated with AS. Second, obtaining labeled data is difficult. There are often far more unlabeled echocardiogram recordings available, but these remain underutilized by existing methods. To overcome these limitations, we introduce Semi-supervised Multimodal Multiple-Instance Learning (SMMIL), …
