Impacts of the edge effect on avian species distribution in the Arcata Community Forest

Christy Wheatley, Environmental Science & Management Undergraduate Student

College of Natural Resources & Sciences

Our study aimed to discover the impacts of the edge effect on bird species distributions within the secondary redwood (Sequoia sempervirens) Arcata Community Forest (ACF). We used the Merlin Bird ID app to record the number of species present at three edge and three interior sampling sites to determine if there was a statistically significant difference between the number of species present. We found that edge sites averaged 7.3 species while interior sites averaged 5.5 species. Our results indicate that the edge effect is being represented in bird habitat selection.

Increasing Chiropractic Prevalence in Black Communities

McKenna Bartlett, School of Applied Health Undergraduate Student

College of Professional Studies

This paper aims to analyze the significant disparities in chiropractic care for Black communities in the United States. Considering there is a substantial difference in the quality of care for Black Americans, it is imperative to be aware of the implications this can have on a community and their trust in healthcare systems. Some of these disparities discussed in this analysis consist of historical segregation, overprescribing opioids for chronic lower back pain, and overall lack of access to care. Efforts to improve care are discussed, such as improving doctor-patient race concordance by increasing the number of Black chiropractic students.

Increasing Motivation and Fitness Levels in Pre-adolescents with Disabilities: A Study in Self-Determination Theory

Adam Thomas, Other Graduate Student

The researcher believes that using self-determination theories of autonomy, competence and relatedness will intrinsically and extrinsically motivate the study participant to achieve a predetermined goal. The purpose of this study was to determine the impact of SDT on the number of jumps completed with a jump rope with a student diagnosed with phonological processing and visual motor coordination deficits within a general education class. The participant displayed incremental improvements in Intervention Phases 3, 4 and 5 but did not reach their goal during any of the five intervention phases.

Indigenous Cultural Enrichment Event

Benny Helms, Other Undergraduate Student

For my Senior project I decided to host an event that was based around two indigenous tribes from California, The Luiseno tribe from Southern California and the Hoopa tribe from Northern California. For this event I had went through the process of gaining sponsorships and demonstration groups to offer 4 types of ceremonial practices. The goals for this event was to highlight diversity, foster understandings, and promote cultural awareness throughout the campus and community of Cal Poly Humboldt.

This poster explores indigenous occupational activity within the Upper Kern River Valley and aims to build a timeline of site use based on the projectile point typologies found at eight different sites.

Individual differences in the coordinated behavioral and physiological immune response to pathogenic threat

Povheng Yam, Psychology Graduate Student

College of Professional Studies

Infectious diseases pose a significant threat to an organism’s fitness and have been a strong selective pressure throughout human evolution. Although we have evolved a sophisticated biological response to pathogenic threat, it can be quite costly to engage the physiological immune system. The Behavioral Immune System encompasses a suite of psychological mechanisms that bias our cognitions and behaviors to facilitate pathogen avoidance. The potential link between the behavioral and physiological immune systems in relatively understudied. The current study aimed to replicate and extend previous work on this link by introducing an additional live pathogenic cue (a "sick" confederate).

Influence of Running shoes on Running Economy, Injury Performance, and Biomechanical Efficiency

Sawyer Stoddard, School of Applied Health Undergraduate Student

College of Professional Studies

Delve into the effects of running shoes on athletic performance, biomechanical efficiency, and injury prevention. Examine the relationship between footwear selection, running economy, and influence it has when running. Assess various shoe characteristics, including design, weight, and midsole properties, to elucidate their impact on stride mechanics and energy usage. Allowing valuable insights to guide optimal shoe choices for maximizing performance and ensuring long-term well-being for all types of runners.

Insight into the Morphology of Human Induced Pluripotent Stem Cells

Josafath Aparicio, Biological Sciences Undergraduate Student

College of Natural Resources & Sciences

Human induced pluripotent stem cells have revolutionized the medical world. These cells come from adult somatic cells and have the ability to differentiate into the three germs layers of development: mesoderm, ectoderm, and endoderm. To better understand the nature of these cells this project attempted to provide insight into the morphology through the use of scanning electron microscopy.

Intergenerational Connections: Silvercrest Eureka, Salvation Army

Myranda Felton, College Corp Undergraduate Student

College of Natural Resources & Sciences

Seniors at Silvercrest are a good example of the troubling statistics for Humboldt County. Over thirty people die of suicide in this county, ages ranging from forty to sixty, each year. BMC Public Health also says that “Approximately 50% of individuals aged over 60 are at risk of social isolation and one-third will experience some degree of loneliness later in life.” The answer is intergenerational connections. Harvard has found that people ages sixty five and older have “higher levels of energy with increased connections.” They have connected this with longer lifespans, which is what we are trying to implement at Silvercrest through volunteering.

Intravenous Vitamin C in Cancer Treatment

Nick Weil, School of Applied Health Undergraduate Student

College of Professional Studies

Senior project literature review of high-dose intravenous vitamin C therapy, and its applications in oncology. This treatment is very safe, and low-cost, making it very valuable, and in need of more attention. This review discusses the history, chemistry, current research, concerns, and the future of this treatment.
