Harmonic Analysis of Currents in Humboldt Bay
Presentation Year: 2024
Steven
Gracy
Physics & Astronomy
Currents can shape the structure and ecology of estuarine environments. Multiyear time series of current data measured by two Acoustic Doppler Current Profilers (ADCPs) in Humboldt Bay, CA, one near the entrance channel and one at the Chevron Port, were analyzed to determine the contributions of the different harmonic frequencies. Spectral analysis of the time series data revealed that the flow is dominated by several tidal harmonics. The three dominant frequencies include M2, K1, and O1, but their contribution varies spatially between the two stations. Additional frequencies in the data indicate interference with topography as well as the more variable wind-induced currents.

School of Applied Health
Various lacing methods have been employed to enhance running performance and mitigate the risk of injuries. Runners have experimented with these patterns to identify the optimal configuration for their running form, anatomy, and sport. This research emphasizes the pivotal role of shoelace techniques in the broader context of ergonomics and injury prevention, highlighting the relationship between how the foot is laced within the shoe and its implications for the overall well-being of the runner. Tight laces with additional contact points adhere the foot to the shoe best but must also leave enough room in the shoe for the runner’s anatomy to perform natural anatomical mechanisms such as receiv

Human Impacts on Songbird Abundance and Diversity
Presentation Year: 2024
Chloe
Good
Wildlife
My study investigates how human disturbances affect songbird diversity and abundance in Arcata, CA. Many songbirds try to adjust their behavior in response to human populated environments; however, adjustments can have intense effects on their survival, and serious ramifications beyond urban settings (Marzluff 1997). My findings aim to better inform conservation efforts of species specific requirements and minimize areas with human disturbances as needed.

My study investigated the nectar preference of Anna’s hummingbirds and whether foraging increased as the temperature increased from winter to spring. The results of this study will aid in determining the best plants to maintain and restore in natural areas in order to maintain a healthy environment. By providing the best nectar solution, we can contribute to maintaining robust hummingbird populations.
Impacts of the edge effect on avian species distribution in the Arcata Community Forest
Presentation Year: 2024
Christy
Wheatley
Environmental Science & Management
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
Presentation Year: 2024
McKenna
Bartlett
School of Applied Health
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.

Individual differences in the coordinated behavioral and physiological immune response to pathogenic threat
Presentation Year: 2024
Povheng
Yam
Psychology
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).

Intergenerational Connections: Silvercrest Eureka, Salvation Army
Presentation Year: 2024
Myranda
Felton
College Corp
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.
