Cursing Practices: Transitions, and Rituals
Charlene Duty

The practice of excessive cursing is understood in teens and early adults as a transition into adulthood, by developing code switching skills, and strengthening kinship bonds. However as our world is increasingly digitized and kids find themselves socializing online at an ever increasing rate, taboo language has experienced a shift that is acutely represented within the boundaries of online gaming. Within the borders of popular combat games, a ritual of offensiveness takes cursing and derogatory terms to extreme use over their microphones within “in game chat” features. This poster examines these two cursing practices side by side, allowing participants to analyze how the culture changes.

The current study used electroencephalography (EEG) to investigate adults’ processing of infant faces with cleft lip/palate before and after surgical repair. We found enhanced N170 responses for faces pre-repair surgery compared to post-repair surgery, suggesting that cleft lip/palate repair surgery may restore a more “normal” N170 response. Additionally, the P200 was smaller for the pre-repair surgery faces compared to post-repair surgery, which likely reflects the P200 responding to “typicality” for face stimuli as the post-repair surgery faces would appear more face-typical.
Candidate Landing Sites for Artemis 3 in Two NASA Candidate Landing Regions Nearest The Lunar South Pole

This will be a poster presentation that is based on summer REU research at SETI. This REU focuses on a landing site for the Human Landing System for the NASA Artemis III mission. This poster is complete with a full abstract and pictures of two of the best candidate sites via satellite imaging from NASA and Arizona State University databases. The sites were chosen based on a list of criteria that must be met inside previously chosen landing site regions near the Lunar South Pole that we're set by NASA.
Testing Gravitational Interactions Below Fifty Microns

Attempts to unify the Standard Model and General Relativity often include features that violate the Weak Equivalence Principle (WEP) and/or the gravitational Inverse-Square Law (ISL). To investigate this, researchers at Cal Poly Humboldt are conducting precision measurements of gravitational interactions below 50 microns. This project employs a torsion pendulum configured as a composition dipole with equal masses of titanium and aluminum. The twist angle and frequency of the pendulum is measured as an attractor mass in a parallel-plate configuration oscillates within submillimeter separations.

Aleck Tan and Breana Esparza will assist Dr. Marisol Cortes-Rincon in mapping the areas between Dos Hombres and Gran Cacao using GIS and remote sensing techniques. Aleck Tan has been using satellite imagery to analyze the vegetation in the area in order to identify the extent of the causeways by applying remote sensing techniques of calculating the Normalized Difference Vegetation Index (NDVI). Breana Esparza has been applying different methods of spatial analysis to create topographic contours of quarries and water features near the site N950. The information gathered would help create a better understanding of how ancient Mayan rural communities lived within their environments.
Sedimentation Risk Assessment in the Lagoa Feia Lake Basin in Brazil using Satellite and Geospatial Data

Lagoa Feia Lake Basin is located in Rio de Janeiro-Brazil, which historically experienced sedimentation impacts due to channel ditching to manage water resources for agricultural practices. This study models the significance of sedimentation in the lake basin intergraded with land-use, soil types, and DEM data using Remote Sensing and GIS techniques. The erosion model was built using the above input variables by applying weighted overlay methods, and the vulnerable areas were mapped. Landsat 8 images were utilized for remote sensing analysis, such as image enhancement indices to detect sedimentation changes over time. The results of the study are useful to implement best management practices

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.

Facial reconstruction is a method whereby the likeness of a person is reconstructed from the cranial skeleton. This projects involved researching facial reconstruction techniques and applying them to casts of hominin fossil skulls in the anthropology teaching collection. Species/specimens chosen to reconstruct include: (1) a juvenile Australopithecus africanus (the “Taung Child”), a 2.5 million-year-old hominin from South Africa; (2) an adult Paranthropus boisei skull; (3) also an adult Homo neanderthalensis found at the La Chapelle Aux-Saint, in France. To complete the reconstructions, we used a combination of tissue depth markers for humans and chimpanzees.
Modification of Turbulent Pipe Flow Equations to Estimate the Vertical Velocity Profiles Under Woody Debris Jams

Large woody debris (LWD) in rivers can increase fish and macroinvertebrate habitat, but also increases the risk of flooding and reduces channel navigability. This research aims to better understand the river hydraulics associated with LWD in order to find a balance between the beneficial and detrimental effects. By modifying equations of turbulent pipe flow, we attempt to estimate the vertical velocity profile of flow under LWD jams and compare the estimated profile to measured profiles from flume-simulated LWD jams.
