This study focuses on media coverage of the opioid epidemic. We analyzed local media coverage from 2013-2018 in the Times-Standard, North Coast Journal, and Lost Coast Outpost. The study is inspired by cultivation theory, which indicates that prolonged exposure to mediated messages influence how people perceive reality. Results indicate that the majority of articles containing the term “heroin” are focused on crime rather than a health, legislation, community engagement, or other key factors that could potentially affect the future outcome of this epidemic.

We present the first survey of extremely high velocity outflows (EHVO) in quasars from the Sloan Digital Sky Survey data release nine quasar catalog (SDSS DR9Q). Our survey draws from the 87,822 spectral targets in DR9Q. EHVO candidates were identified by measurement of one of the transitions due to absorption in carbon ion (C-IV), which appear in the spectrum as broad absorption features. Spectrum analysis was carried out by python codes developed by our group with results confirmed by visual inspection. The presented survey is composed of 45 quasars EHVO ranging in velocity from ~50,000 to 30,000 km/s. Our survey will be made available online as a publicly accessible database.

Patrick’s Point State Park has experienced a tremendous growth of English Ivy that has causing a damage to park resources. The goal of this study was to accurately map English Ivy habitats, estimate coverage, and survey English Ivy colonization effects on tree trunks. The results showed that the English Ivy growth has decreased from 8.0 acres to 6.5 acres between 2015 and 2016 respectively due to park restoration activity supported by volunteer organizations. The English Ivy growth on tree trunks was significant for Western Hemlock and Sitka Spruce. With this project the park will be able to locate the most English Ivy spots that require attention, and monitor their growth rate.

In forensics, stature estimation is a key component of the assessment of skeletal remains. Estimating stature involves extrapolation from the length of long bones. Previous research has indicated environment can result in postmortem shrinkage of bone, and therefore affect stature estimates. This research project examines the extent of bone shrinkage that occurs when bones are exposed to the elements, dried out in a fume hood and submerged underwater. Measurements of bone length were taken at regular intervals. Preliminary analysis indicates a relationship between precipitation and postmortem shrinkage. This study has the potential to aid in assessing the accuracy of stature calculations.
The Homeless Students of Color of Humboldt State University

In the Fall semester of 2015, Humboldt State University experienced an increase in enrollment unlike any in its history; HSU recruited a total 1,429 incoming freshmen, which joined the already-enrolled student body of 7,370. Of that population, 31% was Hispanic-identified, and 31.3% of that population was from Los Angeles alone. Competitive housing on and off campus left many students in housing insecurity; some endured homelessness for a majority of the semester. This ethnographic research spans the Fall 2015 semester as an attempt to analyze the multi-faceted issue of student homelessness. The increase in enrollment provides an opportunity for analysis in our very racialized present.
Assaying the Substrate Activities and Enantioselectivities of Recombinant Flavin-Dependent Monooxygenases toward Aryl Sulfides

Certain Flavin Monooxygenases (FMO) are enzymes with the potential to catalyze single-enantiomer oxidation of aryl sulfides to chiral sulfoxides. Aryl sulfoxides have a wide array of pharmaceutical and agricultural applications, but many of these enantiomers have yet to be selectively and efficiently synthesized. The enzymes examined in this study are FMOs from Mus musculus, Xenopus tropicalis, Homo sapiens, and BVMO4 and BVMO24 from Rhodococcus jostii RHA1. The genes were cloned into a vector for expression in Escherichia coli and whole-cell mediated reactions with various aryl sulfides were performed to determine their activity toward the substrates and to determine the enantioselectivity.
Changing Clothes: The Handmaid's Uniform as a Symbol of Protest
Heather Rumsey
English
Undergraduate Student
College of Arts, Humanities & Social Sciences
The bright red cloak and fearsome white bonnet featured in The Handmaid’s Tale by Margaret Atwood has been internationally recognized as a symbol for protest. Bruce Miller’s Hulu adaptation of the novel propelled this new wave of activism. I argue that the costume functions as a metonym, reacting to larger issues concerning women’s rights. This study examines whether the uniform is a viable protest image or is it being co-opted to get people to buy into a certain social and political system?
Individual differences in the coordinated behavioral and physiological immune response to pathogenic threat

Infectious diseases pose a significant threat to an organism’s fitness and have been a strong selective pressure throughout human evolution. Although we have evolved a sophisticated biological response to pathogenic threat, it can be quite costly to engage the physiological immune system. The Behavioral Immune System encompasses a suite of psychological mechanisms that bias our cognitions and behaviors to facilitate pathogen avoidance. The potential link between the behavioral and physiological immune systems in relatively understudied. The current study aimed to replicate and extend previous work on this link by introducing an additional live pathogenic cue (a "sick" confederate).
From Chaos to Collection: The Costco-Price Collection
Jacqueline Farrington
Geography & Anthropology
Undergraduate Student
College of Arts, Humanities & Social Sciences
The Costco-Price Collection is an assortment of historic artifacts excavated in 1994 from the current Costco site and former city dump in Eureka, California. A portion (619 artifacts) was kept as a teaching collection in the Archaeology Research Laboratory at Humboldt State University, and has been used to educate students and encourage interest in California archaeology. This presentation will showcase the rehabilitation of this collection from its original inherited state in 2013 to its current incarnation as a useful and coherent resource through the three-year timeline.
Utilization of the Arcata Marsh and Wildlife Sanctuary by North American River Otters

North American river otters are a regular sight to see in the Arcata Marsh and Wildlife Sanctuary and have been observed to exhibit different behaviors and activities in various locations of the marsh. By using ArcGIS Pro, visual observations of river otters made by Jeff Black over the course of two years have been mapped out depending on their behavior and activity. I focused on mapping three main behaviors that otters exhibit in the marsh: fishing for fish or invertebrates, hunting for birds, or traveling to/from or through the marsh.
