Creating a Gift for the Future: Digitization Utilizing Omeka.net
Presentation Year: 2016
The Library Scholar Internship team is digitizing historically significant objects from the library’s Special Collections. This process involves more than scanning objects, but publishing to a broader research community using Omeka.net to create digital exhibits. In this poster we discuss our process creating metadata, scanning procedures, researching the collections and publicizing our work. Our goal is to encourage students and faculty to use the library’s resources such as Collaboration Stations, SkillShops, librarians, computer labs, #mondopad and peers to improve and publish their research. The library is a dynamic space for students to work on innovative and collaborative projects.
Creating an Interactive Index Map Using Scanned Images: A Project for the Humboldt State University Library's Special Collections
Presentation Year: 2016
The Humboldt Room special collections at the Humboldt State University Library contains a large collection of delicate and vintage historical maps. Taking action to make searching the archive easier as well as to preserve the fragile status of historical maps has become a necessity. This can be accomplished by creating a “web-based digital map archive” and supplanting it with a Web Map component that allows users to search and download from the digital map archive.This poster introduces the concept of converting the map collection to a digital format, the methods used for developing an interactive web map, and the future status of the project.
Demonstration of Lead Binding for Bioremediation in Engineered RsaA S-Layer Proteins on C. vibrioides
Presentation Year: 2016
Heavy metal contamination of soils and waterways due to industrial processes, such as mining, continues to be a problem in the U.S., such as Flint Michigan. Microbial surface layers (S-layers) have shown promise for binding and sequestering heavy metals. Modifications to the S-later protein (RsaA), in C. vibrioides, could increase this efficiency. Our modified strains absorbed more lead per cell mass. Strains HCm 021, 027, 028 absorbed 197.78 ±2.14, 231.32 ±3.10, and 168.69 ±22.65 (ppm Pb+2/g cells) versus 90.55 +/- 1.07 (ppm/g) for the wild-type. Future goals of this project include determining association constants of lead to cells, and construction of a bioremediation filter.
Development and Validation of the Academic Procrastination Scale
Presentation Year: 2016
Academic procrastination is the intentional delay of starting or continuing progress on school-related work. Academic procrastination often leads to negative outcomes such as submitting late assignments, cramming for exams, and test anxiety. To assess this we created a 21-item Academic Procrastination Scale (APS). The APS showed appropriate criterion (r = .69, p < .000), convergent (r = .49, p < .000), and discriminant (r = .29, p = .001) validity. The APS also showed good internal consistency with an alpha of .88 and a test-retest reliability of r = .75, p = .000. Validity and reliability analyses show that the APS is a valid and reliable measure of academic procrastination.
Duff accumulation around legacy sugar pines in the Russian Wilderness in northwest California
Presentation Year: 2016
Fire suppression over the 20th century has created dangerous conditions in many western forests. Removing fire as a natural disturbance has brought about increased fuel loading and extreme fire behavior in many areas. This study researched the accumulation of duff mounds (decomposed plant material) around legacy sugar pine (Pinus lambertiana) in the Russian Wilderness Area of the Klamath National Forest. Large amounts of fuel beneath trees poses the potential risk of tree mortality, even in a low intensity fire By assessing the dimensions, volume, distribution and physical properties of duff mounds, we can better the variability of how and where duff mounds accumulate.
Early Intervention for Young Children in Improving Future Outcomes
Presentation Year: 2016
The project is based on a review study being done to understand different types of early interventions (0-8 years) that are available to help young children and their families in improving the future outcomes of the children. In this paper, I define early intervention, present different areas and formats, list various programs available in the Humboldt County, and make recommendations for parents and professionals who work with them.
Effect of Foot Orthoses on Energetics and Lower Limb Mechanics in Healthy Adults During Cycling
Presentation Year: 2016
The use of custom foot orthotics and wedging techniques has been recognized in the literature as a method to mechanically alter or improve joint function at the hip and knee. This study investigated the effect of foot orthoses on energetics and lower limb mechanics in healthy adults during cycling. We hypothesized that alterations to medial foot support will affect lower limb mechanics as well as metabolic values. Participants completed an individualized protocol that involved cycling in four foot orthoses conditions at three power intensities. The results of this study provide insights into the use of foot orthoses for; correcting mechanics, improving energetics and reducing injury.
Effects of Habitat on Mesocarnivore Activity in the Coastal Dunes of Northern California
Presentation Year: 2016
The Ma-le'l coastal dunes of northern California have been affected by the invasion of dense European beachgrass. In response, USFWS and BLM have removed beachgrass in an attempt to restore native ecosystem function. Mesocarnivores play vital roles in trophic webs, and previous research has suggested that they are more active in restored dunes than in areas with dense beachgrass. However, distance to nearby coastal dune forests could affect mesocarnivore activity and may have confounded previous work. We conducted an observational study using remote cameras and found the detection rate mesocarnivores declined with distance to forest.
Etching Patterns of Pyroxene Crystals via Scanning Electron Microscopy Determine the Relative Age of Glacial Moraines in Mohawk Valley, northern Sierra Nevada, CaliforniaC
Presentation Year: 2016
Research was conducted in an effort to date the glacial moraines of this area using the degree of etching caused by weathering over time. It was determined that etching of hornblende grains can be used to quantify the age of glacial moraines. Samples were collected from five different glacial moraines from Frazier Falls in the Mohawk Valley of the northeastern Sierra Nevada Mountains. Fine sand samples were cleaned, sorted and analyzed; using soil science techniques. Thirty hornblende grains from each location were individually chosen and mounted for analysis. Backscatter electrons and secondary electrons in the scanning electron microscope were used to analyze the etching of the hornbl
Eureka Consumer Price Index
Presentation Year: 2016
Each year senior capstone students in the HSU Department of Economics provide an updated calculation of a consumer price index (CPI) for Eureka, CA, using Bureau of Economic Analysis methodology and extensive local price data collection. This year the project will also include extensive analysis of each CPI sector such as housing, food, and transportation.
Examining the Roles of Body-Esteem, Health-Efficacy, and Perfectionism on the Eating Patterns of Male and Female College Students
Presentation Year: 2016
This research explored the roles of health-efficacy, body-esteem, and perfectionism on the eating patterns of male and female psychology major college students in Northern California, and found that college students with low body-esteem and high levels of perfectionism tended to have a higher risk for abnormal eating patterns, R2=.60, F(3,61)=11.39, p
Exoplanets: Using Photometry and Spectroscopy to Explore Alien Worlds
Presentation Year: 2016
Over the last 20 years, thousands of planets outside our solar system have been discovered orbiting other stars. The discovery of these extra-solar planets, or exoplanets as they are commonly known, has been made possible by the gathering of photometric and spectroscopic data of stars. We use public data from the Kepler and Hubble space telescopes to analyze photometric and spectroscopic data respectively on select objects of interest. Through analysis of this data, we are able to determine many properties of these exoplanets such as radius, density, temperature and atmospheric makeup. Our long term goal is to find ways to improve current atmospheric analysis methods.
Experience of Gender Nonconforming Students on HSU Campus
Presentation Year: 2016
As the campus population grows at Humboldt State University, so does the number of students who do not fit the male and female dichotomy. These folks who do not fit into this dichotomy are referred to as gender nonconforming. This is a small population on the HSU campus, and there is very little information on this particular group. In an effort to fill the gaps of what is unknown we propose to use three methods: a random survey of 900 HSU students, as well as semi-structures qualitative interviews, and a small number of oral histories from students who are gender nonconforming.
Exploring the role of JNK/cJun Signaling in Apoptosis in Lgl -/- Tumor Promoting Neuronal Progenitor Cells
Presentation Year: 2016
High grade gliomas are aggressive brain cancers that arise from tumor promoting neuronal progenitor cells. The WD40 protein Lethal Giant Larvae (LGL) may suppress brain tumor formation. Mice without LGL develop brain tumors and have a high level of apoptosis, or programmed cell death, which is a key feature of many cancers. cJun is an oncogene involved in cell division, organismal development and regulation of apoptosis through its role as a transcription factor. Apoptosis is mediated downstream by intracellular proteolytic enzymes called caspases. We aim to measure caspase activity in cells with and without LGL protein through observation of its effects on cJun expression.
Following the Money: Capitalist in Communist China - A Bibliographical Project
Presentation Year: 2016
What happens when a planned economy is based on an unplanned economy? In this bibliographical project, we collected sources from all around the world relating to capitalist business and manufacturing in the first decades of the People's Republic of China. This project breaks new ground in historical studies of the early PRC by reexamining the relationship between the Communist Party-State and those capitalists who survived the transition to socialism. With over 500 entries, this is the largest collection of materials on capitalists and private enterprise in Communist China and will most certainly be an aid to any researcher, professional or in-training.
From Chaos to Collection: The Costco-Price Collection
Presentation Year: 2016
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.
From the Post-Soviet to Eurasia: Regional Constructs a Quarter-Century after Independence
Presentation Year: 2016
This project, an overview of an in-progress edited book, interrogates Eurasia as a form of regional definition for the states that gained independence after the USSR’s breakup, arguing for the continued relevance “post-Soviet” as a regional construct. The idea of the post-Soviet is positioned as a heuristic device to evaluate existing prior attempts at regional definition. Path-dependency as a concept suggests that preexisting institutions condition the institutional form that follows political transition; the condition of path-dependency remains relevant across the post-Soviet successor states.
Habitat Suitability and Selection of Northern Pacific Rattlesnakes at Multiple Spatial Scales
Presentation Year: 2016
An investigation into the distribution of suitable habitat for the northern Pacific rattlesnake at multiple spatial scales. Niche modeling techniques were used to determine where suitable habitat for this species actually exists within its known range. Additionally, I examined geological, thermal, and other differences in habitat characteristics between the rocky outcrops rattlesnakes use as hibernacula (i.e., dens) and unoccupied outcrops.

History of Prior Concussion Has No Negative Effect on Neurocognitive Performance Following Competitive Seasons in Uninjured Collegiate Soccer Athletes
Presentation Year: 2016
Researchers have hypothesized a dose-response relationship between concussion history and decrements in neurocognitive function. However, dose-response evidence is uncertain among soccer athletes. Athletes from the HSU men’s and women’s soccer teams completed a computerized neurocognitive test before and after a soccer season. We observed no significant changes from preseason to postseason in ImPACT composite scores across any concussion group (p>0.05). Prior concussions did not result in immediate decreased neurocognitive function among collegiate soccer athletes. Participation in intercollegiate soccer for 1 or 2 competitive seasons does not negatively influence neurocognitive performance.
