Mapping Ancient Maya Ceramics in BelizePresentation Year: 2020
- Jason LaugesenAnthropologyUndergraduate Student
- Jasmine BrownAnthropologyUndergraduate Student
- Michael McDermottAnthropologyStaff
A common form of relative dating in Mesoamerica is through ceramic chronology. This is due to the fact that ceramics preserve well, especially the humid environment. Through cross-dating across sites, different types of ceramics can be arranged with loose sets of dates. HSU’s Dos Hombres to Gran Cacao archaeology project in Belize has been collecting ceramic data since 2009, and the information has been placed into GIS to view and query visually. This focuses on one of the larger settlements studied by the project, N950. The initial GIS processing uses N950’s Structures 30, 32, and 36. The map produced represents when the ceramics were found and where they are relative to each other.
Math Modeling Competition: Drowning in PlasticPresentation Year: 2020
- Emily OrdMathUndergraduate Student
- Ryan MyersMathUndergraduate Student
- Alyssa JohnsonMathUndergraduate Student
As participants of the 2020 Math Modeling Contest, we modeled the outcomes of a hypothetical plastic tax. We implemented this tax to help slow the world's plastic pollution problem.
Mathematical Modeling of Tumor and T-Cell DynamicsPresentation Year: 2020
- Kamila LarripaMathematicsFaculty
- Minh NguyenMathematicsUndergraduate Student
We propose and analyze a mathematical model for the interaction of T cells and tumor cells using a system of ordinary differential equations with the goal of understanding immune-mediated tumor rejection. We explore parameter sets which yield qualitatively different behavior. A major goal of this work is the determination of parameters which play a critical role in remission or clearance of the cancer in the model. In addition to our ODE model, we present an agent-based model to illustrate how naïve T cells are primed in the lymph node to fight cancer. This priming involves antigen presentation, cytokine signaling, and chemotaxis.
Meta-Analysis of CSR Accounting Related ResearchPresentation Year: 2020
- Joshua R ZenderSchool of BusinessFaculty
- Yi Hsuan (Lily) HuangSchool of BusinessGraduate Student
The purpose of this meta-analysis was to examine the effect of Corporate Social Responsibility (CSR) disclosures on firm financial performance. Standard meta-analytical procedures determining inclusion criteria, literature searches in electronic databases, and coding procedures were used to identify and synthesize articles retained for this analysis. PRISMA guidelines were utilized as search strategies, as well as interpret effect sizes and quantify research findings. Moderator and outcome variables were assessed using coding procedures. A total of 136 studies were surveyed and categorized. Results from meta-analyses indicated an overall moderate effect for US companies.
Mindfulness at Coastal Grove Charter SchoolPresentation Year: 2020
- Eva YorkSocial WorkGraduate Student
Coastal Grove Charter school is a K - 8th Grade school in a rural area in Northern California located on traditional Wiyot Land. Studies find that youth benefit from learning Mindfulness in terms of improved cognitive outcomes, stress reduction, social-emotional skills, and well-being. These benefits may lead to long-term improvements in the life course development. For the Master’s project Eva assisted Coastal Grove Charter School in bringing ten weekly Mindfulness lessons into the second and sixth grade classroom during the 2019 – 2020 school year.
Missing and Murdered Indigenous WomenPresentation Year: 2020
- Lily DownsCollege of Arts, Humanities, and Social StudiesUndergraduate Student
When Oliphant v. Suquamish was passed it completely changed the paradigm in rape cases. It created a legal loophole for perpetrators to escape without punishment due to a jurisdictional power shift to federal governance. This allows more sexual assaults and abductions on reservations because there is not readily accessible or adequate repercussions for the behavior of rapists. The exploitation of mother earth’s resources can be related to the violation and objectification of Native American bodies as both were violated by the settler state.
Moving NorthPresentation Year: 2020
- Christina BewleyGeologyUndergraduate Student
- Mariah GrahamGeologyUndergraduate Student
- Thomas BoernerPhysicsUndergraduate Student
Mathematically modeled herring and mackerel fish migrations in the North and Norwegian Seas, related it to global temperature rise and and how it will affect the small Scottish fishing industry. This project was for a mathematical modeling competition for HSU.
Novel Tests of Gravity Below Fifty MicronsPresentation Year: 2020
- Frank TrombettaPhysicsUndergraduate Student
- Alyssa JohnsonPhysicsUndergraduate Student
Gravity has been tested rigorously at distance scales from 1cm up to astronomical distances. The experiment being run in Humboldt State Universities Gravity Lab seeks to test gravity at previously untested distances below the centimeter level. To do this, a pendulum is suspended by a torsion fiber and oscillates in front of a movable mass. By moving the mass back and forth, one can measure a gravitational force on the pendulum by looking at the twist in the fiber. The data from the pendulum are then compared with well established theories of gravity to see if the accuracy of the theories at large distances translates to smaller scales.
Offshore Wind Resource AssessmentPresentation Year: 2020
- Christina OrtegaSchatz Energy Research Center / Environmental Resources EngineeringUndergraduate Student
Offshore wind energy has enormous potential to help meet California’s 100% clean electricity target. The Schatz Energy Research Center at Humboldt State University is studying the feasibility of offshore wind farms in Northern California. One project, funded by the Bureau of Ocean Energy Management (BOEM), models the power generation from different size offshore wind farms including 50, 150 and 1,800 MW, each located 20-30 miles offshore. The results show that the wind speeds in this region are some of the highest on the West Coast, producing up to 7,540 GWh/year for the largest MW wind farms. This represents 900% of Humboldt County’s electrical needs and 3.8% of California’s demand.
Outreach at CCAT: Evolving, Facilitating, and Encouraging Local ActivismPresentation Year: 2020
- Sophia MagaAnthropologyUndergraduate Student
This ethnography focuses on how outreach is cultivated, idealized, and put into action by employees and volunteers at CCAT. The research takes place at Humboldt State University at the Campus Center for Appropriate Technology (CCAT). This project aims to ask how the outreach programs at this particular Associated Students organization are structured, interact, utilized, and overall encourage local activism. The methods conducted include participant observations, collected artifacts, naturally occurring conversations, surveys, formal and informal interviews. The findings of this research highlight the necessities for student run organizations and awareness-building communities.
