This study highlights the interaction between uncertainty and rhetoric on the support for policies such as abortion. Clinton’s affirming rhetoric created higher support for abortion because highly uncertain individuals define the self by expressing polarized group-based attitudes (Gaffney et al., 2014). Political leaders may be able to gain support for causes that are salient to their party identity by utilizing affirming rhetoric rather than negating rhetoric.
Reserve, Symptoms, Sex and Outcome Following a Single Sports-Related Concussion
Summer Anne Thornfeldt

Graduate Student
College of Professional Studies
The study addressed reserve and symptoms following a single sports-related concussion (SRC). Reserve is the biological/cognitive differences between individuals that protect against cognitive changes following a SRC. A SRC can lead to brain damage, and thus a loss of reserve. The ImPACT is a neurocognitive test taken before an athletic season and following a SRC, which was used as a proxy for reserve. Symptoms were explored using PCSS, a symptom checklist. It was found that those with low pre-SRC reserves had better outcomes that those with high pre-SRC reserves, and that females reported more symptoms than males. Reasons for these findings and suggestions for SRC management were explored.

Researchers found that fungi that grow faster tend to be less resistant to changes in temperature and moisture. Exploring the relationship between a fungus’s growth rate and moisture tolerance, our team used a system of differential equations to model the decomposition rates of woody material by different fungi to understand how decomposition would be affected when the species are in competition.

The Cal Poly Humboldt 3D Digital Herbarium improves upon current digital herbaria by incorporating 3D models of flora in addition to images of specimens from physical herbariums. These annotated models in addition to a social component implemented with the integration of iNaturalist make for the most immersive, fun and memorable experience of any digital herbarium out there.
Macroinvertebrate Abundance Decreases Waterfowl Diversity
Rachel

Wildlife
Undergraduate Student
College of Natural Resources & Sciences
The relationship between macroinvertebrate communities and waterfowl is still an understudied topic. I wanted to know how macroinvertebrate richness could influence waterfowl species and their abundance. I conducted my study at the Arcata Marsh and Wildlife Sanctuary, setting up random systematic sites 100 meters from each other. Each site was sampled for waterfowl point counts within a 50 meter radius and invertebrates were collected via D-net sweeps and a core sample. Invertebrates collected were then euthanized in 70% ethanol and identified to family in the lab. My results showed a negative correlation between macroinvertebrate abundance compared to waterfowl diversity.

Buying a new water bottle seems easier for some, but harder for our planet. The use of plastic is a global issue and should be concerning. We partnered up with Zero Waste Humboldt (ZWH), a nonprofit organization, to assist in their Refill-not-Landfill Network Project, which is a project that has saved over 100,000 water bottles from the landfill. We assisted in this project by updating their website with an updated map of the 10 water refilling stations that were donated by them through a federal grant. We are presenting at IdeaFest so community members can gain an awareness and interest in being conscious about waste production and mindful about single-use plastic bottles.
Honor Our Elders
Josh
Ringland
Social Work
Graduate Student
College of Professional Studies
Older adults are a growing population in the United States and many elders suffer from physical, sexual, mental, isolation and financial abuse without any obvious signs. Through the research and evaluation of a growing number of elder abuse cases, Humboldt County’s Civil Grand Jury issued a report, Silver Tsunami Warning, explaining the concerns of elder abuse. Through this community project, my community partner, Adult Protective Services and I will bring mindfulness of elder abuse through promoting World Elder Abuse Awareness Month, advocate prevention of elder abuse, and educate how to report elder abuse through a visual campaign of banners advertised throughout Humboldt County.

TIBIAL ACCELERATION AND EMG DIFFERENCES BETWEEN ISOCALORIC HIGH-INCLINE WALKING AND LEVEL-GRADE JOGGING

Graduate Student
College of Professional Studies
This study will aim to determine the effects of high-incline exercises on impact forces (tibial acceleration) and various muscle activation metrics, including peak force, the area under the curve, and fatigue parameters between isocaloric exercises: walking at a high incline and jogging on level grade.
