Mapping the Sierra Nevada HSU advanced geospatial students map a variety of topics to accompany text in a forthcoming book about Environmental Issues in the Sierra Nevada.
Mapping Tibet
- Patrick WoodGeographyUndergraduate Student
- Nathaniel DouglassGeographyUndergraduate Student
College of Arts, Humanities & Social Sciences
This project aims to show two different styles of Cartography to represent the same geographic area, Tibet. The first map is paper map, a mapping project of Tibet and of Tibetan toponyms. The paper map focuses on the region rather than the geopolitics of the region and displays toponyms that reflect Tibetan culture. The second map uses a web based interactive platform to display the various routes that HSU students have taken between 2000 and 2014, while conducting research in Tibet. The web map hopes to consolidate the previous field studies conducted, into an interactive database for future research to reference.
Mazes and Memory: Does lifestyle affect spatial memory and ability?
- Josue RodriguezPsychologyUndergraduate Student
- Undergraduate Student
College of Professional Studies
This study aims to address whether differences in spatial ability and memory will be found among those who have active lifestyles, inactive lifestyles, and those who play video games. Spatial ability was examined by having participants become familiarized and then tested on a 3-D computerized maze. Participants were tested on memory and spatial components when asked to recollect the spatial layout of the computerized map.
Mental Health Stigma and Help Seeking Among College Students
- Benjamin SkillmanPsychologyUndergraduate Student
College of Professional Studies
The purpose of this study is to examine the relationship between mental health stigma and help-seeking intentions and behaviors at a rural university and explore differences in patterns of help seeking by race/ethnicity. We hypothesize higher levels of mental health stigma will be related to lower levels of help-seeking. Multiple regression will be used to examine predictors of mental health help-seeking. We found that higher levels of stigma lead to a lower likelihood to seek help.
MICP Bio-cementation for Uniform Improvement of Heterogenous Sands
- Chelsea ObeidyEnvironmental Science: Ecological RestorationUndergraduate Student
College of Natural Resources & Sciences
Microbially Induced Calcite Precipitation (MICP) is an environmentally-conscious bio-cementation ground improvement technology. In the process, microorganisms containing active urease enzymes are utilized to induce the precipitation of calcite on soil particle surfaces and contacts. MICP can be utilized for; strengthening soils to support structures, mitigation of earthquake-induced liquefaction, prevention of soil erosion, improvement of slope stability, and immobilization of divalent cation contaminants.
My Service Learning Experience with CalTrout
- Connor StewartEnvironmental StudiesUndergraduate Student
College of Arts, Humanities & Social Sciences
My service learning project consisted of working with Mary Burke, Project Manager at CalTrout Arcata. Together we planned/coordinated special events for this year's Humboldt Steelhead Days celebration which included fun/educational activities, workshops, conferences, and engaging art experiences. We worked together with several local residents and organizations who all helped put these events together for a common goal of getting involved with the local community and helping educate them about CalTrout and other's work in watershed and salmon habitat restoration.
Nanodiscs stabilize Anabaena sensory rhodopsin trimers for regulatory binding studies

Anabaena Sensory Rhodopsin (ASR), a photoactive membrane protein, undergoes light induced conformational change associated with release of a transducer protein, ASRT. This complex is proposed to control transcription. However, DNA binding to ASR has not been demonstrated. We prepared ASR in soluble nanodiscs. Our data show ASR nanodiscs had a retinal absorbance shift (≈548 - 537 nm). DLS of ASR nanodiscs, separated by SEC, displayed two populations (21.9 ± 6.3 and 31.1 ± 12.5 nm). These populations may represent varying oligomeric states. Preliminary data from crosslinking studies suggest ASR exist in a trimeric state. We conclude ASR is stabilized in the nanodiscs, enabling studies of ASR.
Nanoscale Modifications to the RsaA S-Layer Protein Enhance Lead binding in Whole Cells

College of Natural Resources & Sciences
Heavy metal contamination of soils and waterways due to industrial processes, continues to be a problem in the United States. Recent reports indicate that microbial surface layers (S-layers) are able to bind and sequester heavy metals, thereby removing them from the environment. Our approach is to enhance this process for heavy metal bioremediation. Using a highly sensitive fluorescent dye, lead remediation was measured in the nanomolar range. Results show that upon exposure to 39.0 nM Pb solution engineered C. vibrioides strains Hcm 027,028, remediated the solution to, 9.6 ± 0.3 nM, 9.0 ± 0.2 nM respectively and 13.3 ± 0.1 nM for the wild type.

Humboldt State University received a two-year grant from the NCAA and the U.S. Department of Defense to expand upon the existing study that investigates concussive and repetitive head impacts in NCAA student-athletes. This collaboration is to further understand the neurobiopsychosocial nature of concussive injury and recovery to enhance the safety and health of our collegiate student-athletes, service members, youth sports participants and the broader public. At Humboldt State, researchers have conducted baseline and post injury monitoring of neurocognitive, motor control, and behavioral data in 638 athletes from all sports. The poster will have current results from the CARE consortium.
Needs Assessment for Resource Compilation for Persons Experiencing Homelessness While Caring for a Companion Animal
- Sophia Gang-HalvorsonSocial WorkGraduate Student
College of Professional Studies
Individuals facing poverty and homelessness can be denied housing when care-taking for a companion animal. Sometimes a refusal of housing is caused by rules which prohibit companion animals in housing, so the preference is to remain homeless. My project provides a compilation of local, free, and low cost resources to help provide for the companion animal’s care. A needs assessment with persons facing long-term homelessness informed the list. The compilation will allow a person facing poverty to make informed choices among resources in the community that would facilitate a healthy human-companion animal relationship regardless of status of homelessness.
