A Picture Worth a Thousand Words: Factors Influencing Disability Accommodations
Presentation Year: 2024
Alicia
Martin
Psychology
Not all disabilities are apparent; you cannot identify a person with disabilities just by looking at them. This study aims to address whether professors’ disability-related attitudes, perceptions of accommodation reasonableness, and willingness to provide accommodations differ when a student’s disability is recognizable (student is pictured in a wheelchair), unrecognizable (student is pictured in a chair), or when no visual is present (standard documentation control) and whether the professor’s level of disability-related knowledge and perceptions of institutional support mediates this relationship.

A Prediction Model of Nathan's Jacket Preferences
Presentation Year: 2024
Nathan
Boone
Psychology
Despite the utility and ubiquity of statistical modeling in everyday life, many introductory statistics students struggle to connect their coursework to their interests. Predictive models can be applied to a broad range of topics, from the global scale to the individual. The current poster presents a model built to predict how highly the author will rate a new jacket, using ratings of 39 other jackets as reference points. Using jacket measurements, marked size, and price as predictors, the model was able to explain 77% of the variation in the author’s jacket preferences. This poster helps show students that they can apply statistical modeling to their own interests.

A Survey of Shrew (Soricidae) and Mole (Talpidae) Mortality in Arcata, CA
Presentation Year: 2024
Christina
Giltzow
Wildlife
In the Arcata Community Forest, many moles (Talpidae) and shrews (Soricidae) have been found dead along walkways. I investigated starvation, cold temperatures, age and toxin exposure as possible causes for these mortalities. I performed necropsies on 12 specimens including Trowbridge’s shrew (Sorex trowbridgii), shrew mole (Neurotrichus gibbsii) and coast mole (Scapanus orarius). and sent tissues as well as 3 additional specimens to UC Davis for toxicological screening. Body condition, cold temperatures and age did not appear to be linked to mortalities. The toxicological screens were negative for tested organic chemical compounds. The mortalities of these insectivores is still a mystery.
Affects of Common Fishing and Recreational Beaches on Dead Seabird Abundance Found Onshore
Presentation Year: 2024
Nikkie
Villagrana
Wildlife
The objective of this study was to determine whether proximity to fishing communities has an affect whether or not I will find more dead seabirds on those beaches. There is evidence to suggest that one of the highest causes of plastic pollution is by commercial fishing litter. Plastic pollution has been one of the leading causes of seabird death and I aim to bridge the gap in knowledge by whether or not I find more dead seabirds onshore on the beaches that are linked to popular fishing communities in Humboldt County.
Agent-based Modeling of Microglia Behavior in the Context of Alzheimer's Disease
Presentation Year: 2024
Emmanuel
Mezzulo
Mathematics
Our research investigates the role of microglia, the resident immune cells of the central nervous system (CNS), in the progression of Alzheimer's Disease (AD) using an agent-based model (ABM). Microglia cells, which typically act almost as neuronal guardians in the CNS can, under certain conditions, inadvertently contribute to AD progression if they become dysfunctional. By simulating microglia, neurons, and their interactions with signaling proteins, our ABM sheds light on the complex dynamics underlying the progression of AD, and has a the potential to inform therapeutic targets in AD treatment down the line.

Anabaena Sensory Rhodopsin Membrane Protein
Presentation Year: 2024
Jacquelyn
Amadeo-Ranch
Chemistry
Rhodopsins are light-sensitive proteins within the G-protein coupled receptor (GPCR) family that convert photons into intracellular chemical signals that perform downstream biological functions. Anabaena sensory rhodopsin (ASR) with a 6x-His tag was isolated and purified using Ni-NTA affinity chromatography after evaluating clones of induced E. coli transformed with a pET15b plasmid. The most viable clones discovered from this study were BU3E and Box A. SDS-PAGE gel electrophoresis confirmed the protein size of 20.65 kDa. These results indicate that these 2 strains can be utilized for further studies on ASR function in nanodiscs.
ANALYSIS OF ACIDITY, CO2 AND OXYGEN CONCENTRATION DURING SUMMER UPWELLING CONDITIONS IN HUMBOLDT BAY, NORTHERN CALIFORNIA
Presentation Year: 2024
Lindsey
Fischer
Oceanography
This project took place over summer of 2023. We set sensors in Humboldt bay in June and again in August leaving them out for three days. These sensors tracked alkalinity, temperature, and oxygen levels within the water. From this we could look at how summer upwelling changed the water chemistry from June to August.

Seawater samples are to be measured for the iron concentration content. We measured standard samples to better understand what concentration ranges we could measure. We are currently working on optimizing the method to measure higher concentrations.
Around the Bay in 80 Days: Investigating the Relationship between Bird Diversity and Plants
Presentation Year: 2024
Quinlan
House
Wildlife
The goal of this study was to investigate the relationship between plant species richness and bird diversity within the area of Humboldt Bay situated in north-western California. Humboldt Bay hosts a unique array of natural areas such as redwood forests, coastal dune forests, and wetlands. We examined the effect of plant species richness and diversity on bird diversity in these three habitats around Humboldt Bay by conducting point counts, plant species censusing, and plant density sampling across 10 plots at each habitat.
Assessing Attitudes Toward Law Enforcement and Civilian Law Enforcement Review Boards in Humboldt, California
Presentation Year: 2024
Joshua
Worthington
Psychology
The current state of policing in the United States is a heavily politicized issue. In response to instances of excessive police force on vulnerable populations, civilian law enforcement review boards (CLERBs) were developed to improve accountability. In this study, we investigated support for CLERBs and attitudes toward law enforcement in Humboldt County. Drawing from the social identity theory framework and intergroup contact theory, our work shows that people’s beliefs about how marginalized communities are treated by law enforcement predicts their attitudes toward law enforcement, and this in turn predicts support for CLERBs. We discuss these relationships and their implications.
Attitudes of Recognizable and Unrecognizable Disabilities in Various Contexts
Presentation Year: 2024
Alicia
Martin
Psychology
Some disabilities are apparent (i.e., recognizable), while other disabilities are not (i.e., unrecognizable). Different situational contexts (i.e. dating, marriage, work, classroom) and the type of disability being judged (recognizable or unrecognizable) may impact one’s attitudes towards those with disabilities. In addition, one’s own personal characteristics (e.g. gender, sexual orientation, and disability status) may also impact one’s disability attitudes.
Benefits of Birth by Water Immersion

Water birth has always been a controversial topic amongst expecting mothers, and I wanted to research the outcomes of water births to see if it really is as controversial as people think. In my research I highlight the benefits of birth by water immersion on both maternal and neonatal physiology.
Benefits of Physical Exercise On Motor and Non Motor Aspects in Parkinson's Disease
Presentation Year: 2024
Ebony
Isaiah
School of Applied Health
Parkinson's Disease (PD) is a neurodegenerative disease that tends to affect the older adult population. The disease slowly takes away motor functioning and has negative repercussions on the individuals mental health. My research explores the interventions that physical exercise can have on non- motor and motor functions instead of using the medications that are prescribed for PD. The use of medications that are provided with long term use can be detrimental to motor function. The goal of this research is to help maintain health related quality of life and independence for those with PD.

Andrea
Lugo
School of Applied Health
A comprehensive overview of the relationship between traumatic brain injuries (TBI) and the development of neurodegenerative diseases such as Alzheimer's Disease and chronic traumatic encephalopathy (CTE). The poster delves into the critical roles that the proteins tau and beta-amyloid play in the neurodegeneration associated with TBI, suggesting a strong link between TBI and subsequent neurodegenerative conditions. It calls for increased research into treatment strategies and an improved understanding of TBI’s long-term effects.
