COVID-19 brought about unprecedented difficulties for college students. Challenges associated with online learning, such as one-way interactions, presented obstacles to college engagement. We explored the role that instructors play in fostering greater academic involvement. Specifically, we examined the effects of autonomy support. Autonomy support involves encouraging students to explore their own interests and self-regulate. We posited that autonomy support would predict, respectively, greater self-esteem and mastery-approach goals for students. In turn, we expected that these effects would predict greater engagement. Our findings highlight the importance of autonomy support.

20% of CSU students received a failing grade in Calculus 1 between 2019 and 2021. As a required course for many STEM majors, Calculus 1 outcomes have an impact on many students. When staff discuss different teaching strategies and ways to use resources, it’s natural to compare failure rates between campuses. Different CSU campuses have different student populations, so a direct comparison of outcomes may be unfair. The proposed poster describes the process of designing an analysis that could carry out a standardized comparison of calculus outcomes across campuses. Attendees will be invited to interact with the poster by adding relevant variables and pathways with sticky notes and markers.

We gathered biological materials from animals around Humboldt County and used their stable oxygen and carbon isotopic signatures to create an isotope map of the Humboldt area. Samples of bone, teeth and shell were collected in various areas of this county. Samples were processed at the HSU Biological Anthropology Research Center (BARC) and then sent to a stable isotope facility to be analyzed. This information will be distributed in a Geographic Information System (GIS) map. This project is part of an ongoing project at BARC that aims to create a map to help identify the region of origin of animal and human remains, and address ecological questions.

World of Warcraft, an online fantasy game, connects more than 10 million players worldwide in a multiplayer story-based adventure. Each player builds a character and plays through game content individually or in groups called guilds. Through participant observation over the course of a year, this study of one guild found: social/hierarchical bonds/structure are reinforced in all group activities; and the correlation between individual time investment in guild play/communication and group cohesion. This research contributes to existing scholarship on online sociality by providing insight into the role online gaming plays in connecting people across time and space in new forms of community.

Municipal solid waste (MSW) aka. trash , is one of many stressors on global climate change. An estimated 19,832,501 metric tons generated within a year alone in California. Accumulation of trash can spread into creeks and parks.Trash flow can be mitigated through the use of waste and recycling receptacles.This study observers bus stops that are in proximity to selected creeks and parks based on 100, 200, and 300 meter zones of the Arcata Red and Gold Bus Routes.The Red Route buffer zones intersecting greatly with nearby creeks and parks.Community members and stake holders can provide further input where receptacles are most beneficiary for local green-space and city planning cost.

Alzheimer’s Disease (AD) is a neurological disorder that destroys memory and other cognitive functions. Several scientific findings have connected dysfunctional microglia, a type of immune cell, to AD progression. We created an agent-based model to simulate the interactions between microglia and their environment, addressing dysfunctional microglia's effect on AD. Our model represents a two-dimensional slice of the hippocampus, depicting microglia's ability to move, metabolize glucose, and interact with the blood brain barrier and amyloid beta plaques. We applied treatments of metabolic boosting and exercise to our model to study how varying treatment intensities can impede AD progression.

Passive stains, transfer stains and projected/impact stains will be created with various tools and tested on multiple surfaces including: cotton, linen, and carpets. The components of the Bovine blood versus stage blood will be used for analysis and comparison. This research will help determine if synthetic blood provides an accurate representation for bloodstain pattern analysis in research. After all experimental work and calculations are complete, statistical analysis will be conducted to determine the statistical validity of using synthetic blood alternatives to analyze bloodstain patterns.

Students are impacted by differential modes of stimuli presentation while learning in multimedia environments. In the classroom, lecturers often display written text that corresponds with their spoken instruction, but how are students impacted by this? This study aims to address how visual (text), auditory, and pictorial stimuli in isolation or combination pertaining to the same novel subject affect recall accuracy. A cross-sectional between-subjects design was utilized in the study, and we found that students did better on recall questions when they were either taught with auditory, textual and pictorial information, or taught with auditory and pictorial information.

Humboldt State University current HVAC (Heating, Ventilation, and Air Conditioning) system relies on the use of natural gas boilers. This project proposes to switch HSU's current HVAC system to electric air source heat pumps. Unlike natural gas broilers, electric heat pumps do not burn fuel onsite to generate and move heat. Transitioning building heating systems from natural gas to electrically powered systems would reduce the GHG emissions for HSU. In the HSU Climate Action Plan, it was reported that natural gas usage contributed to at least 60% of HSU’s 2014 carbon emissions.

This project explores the spatial distribution of automobile title lenders across four metropolitan areas. Automobile title loans are specific form of alternative finance that targets individuals who do not have access to traditional forms of credit. Our research shows that the spatial distributions of these alternative financial service providers concentrate in lower income neighborhoods where residents tend to be poorer, less educated, and less white. Thus, there are clear class and racial dimensions to the marketing, spatial presence, and consumption of these alternative loan products.
