What's So Great About The Alternative? Understanding Motivations For Participating In Humboldt County Alternative Food Networks, Jessica Smith

Cal Poly Humboldt theses and projects

Participation in alternative food networks such as farmer’s markets, community supported agriculture (CSA), and community gardens has become an increasingly popular way to express opposition to the current industrial food system. Food justice scholars often criticize alternative food networks for operating within a neoliberal economic framework and suggest that structural inequalities within the food system are not able to be addressed by alternative food networks in the same way they are through food justice or food sovereignty. The goal of this research is to discover individual motivation behind participation in local alternative food networks in Humboldt County. I am curious …

Rangewide Tidewater Goby Occupancy Survey Using Environmental Dna, Michael Sutter

Cal Poly Humboldt theses and projects

Rangewide monitoring of fish species is critical for determining status and trends in abundance and distribution; however, implementations of large-scale distribution surveys have generally been constrained by time and cost. This study uses environmental DNA (eDNA) to monitor the presence or absence of two endangered tidewater goby species, the northern tidewater goby (Eucyclogobius newberryi) and the southern tidewater goby (Eucyclogobius kristinae), across their combined geographic range that encompasses the entire California coast (1,350 km).A multi-scale occupancy model designed specifically for eDNA methods was used to account for imperfect detection and to estimate true site occupancy. A …

Post-Fire Regeneration And Fuel Succession Patterns In Hesperocyparis Bakeri Forests, Bret Anthony Mcnamara

Cal Poly Humboldt theses and projects

Climate change is predicted to cause widespread redistribution of suitable tree habitats, as well as increase the size and frequency of wildfires in the western United States during the forthcoming century. Rare serotinous conifers may have heightened sensitivity to the impacts of both fire regime and climate shifts for multiple reasons. First, the rapid spatial rearrangement of suitable habitat will disproportionately affect trees with constrained seed dispersal capabilities, and limited dispersal is a trait associated with some genera of serotinous trees. Second, a number of serotinous conifers depend on fire disturbances for regeneration, though with the expected increase in annual …

The Effects Of Ocean Acidification And Reduced Oxygen On The Behavior And Physiology Of Juvenile Rockfish, Corianna H. Flannery

Cal Poly Humboldt theses and projects

As climate change progresses, the frequency and duration of upwelling events that bring low pH, low dissolved oxygen (DO) water to nearshore habitats are expected to increase. In addition, long-term global changes in ocean pH and DO are expected to occur within the next few decades to centuries. Locally, there have been documented reductions in near-shore pH along with the expansion of oxygen minimum zones within the California Current System. However, very few studies have investigated the potential interactive effect of these stressors on temperate reef fish. For this thesis, two sets of laboratory experiments were conducted to determine the …

Stormwater Management In Philadelphia: The Importance Of Green Stormwater Infrastructure And Community Involvement In Greater Citywide Sustainability, Julie Groff

Cal Poly Humboldt theses and projects

In 2000, the Environmental Protection Agency (EPA) found the City of Philadelphia to be in violation of the Clean Water Act (CWA) of 1972 due to insufficient stormwater infrastructure. In 2011, Philadelphia initiated a 25-year, citywide plan called Green City, Clean Waters to reduce stormwater runoff by implementing green stormwater infrastructure (GSI). The plan promised significant community involvement in the process. I conducted semi-structured interviews with City employees and individuals in the community that have partnered with the City to administer GSI and participant observation of community meetings and used them to explore different neighborhoods’ experiences with Green City, Clean …

S100b As A Potential Biomarker For Concussion In Male And Female Collegiate Rugby Athletes, Monica L. Ortiz

Cal Poly Humboldt theses and projects

Sport related concussions are among the top ten most common sport injuries. Substantial and mounting evidence points to extensive short and long term negative consequences from mismanaged sport related concussions. Consequently, researchers have called for better diagnostic concussion tests that are rapid, reliable, sensitive, specific and objective. The purpose of this research was to determine the ability of salivary S100B to detect concussions, predict concussion symptom resolution time, and correlate with changes in neurocognitive performance over the course of one athletic season. A repeated measures of salivary S100B and neurocognitive performance using the ImPACT test and a concussion symptom questionnaire …

Sex-Specific Habitat Selection Of Rough-Legged Hawks (Buteo Lagopus) Wintering In Western North America, Genevieve Christa Rozhon

Cal Poly Humboldt theses and projects

The rough-legged hawk (Buteo lagopus sanctijohannis) is one of the most under-studied raptor species in North America. As a species that exhibits reversed sexual dimorphism, sex-specific habitat preferences may exist. To investigate rough-legged hawk sex-specific habitat selection preferences, we equipped 17 rough-legged hawks (n = eight females, nine males) with GPS backpacks on their wintering grounds (n = six study areas) during the winter months of 2014 and 2015 in five states in western North America. I analyzed rough-legged hawk habitat selection in relation to sex at four spatial scales: nocturnal roosting site, 50% core range, 95% winter …

Stability For A Small Historic House Museum: Drafting A Collection Management Policy For The Trinidad Museum, Alexandra Mackay Cox

Cal Poly Humboldt theses and projects

A museum exists and is defined primarily by its collection. It is therefore important for a museum to manage its collection effectively while preserving it for long-term use. The size and scope of the museum's collection will determine the complexity of its policy. As such, all museums, including small ones, need a well-defined Collection Management Policy (CMP). This policy outlines what and how to collect, defines the development and use of the collection as well as procedures for the care of the collection, the loaning of items and removing of items from the museum's collection. The Trinidad Museum, a small …

Characterizing Habitat Preference In Three Nearshore Reef-Associated Fishes Through Collaborative Research, Public Data, And Open Source Software, Ian D. Kelmartin

Cal Poly Humboldt theses and projects

Black rockfish (Sebastes melanops), canary rockfish (S. pinniger), and lingcod (Ophidion elongatus) are important species in Northern California’s nearshore recreational and commercial fisheries. These species are associated with nearshore rocky reefs and are among a suite of species intended to benefit from the establishment of the marine protected area (MPA) network along the Northern California Coast in 2012.

Many aspects of the North Coast’s nearshore ecosystem remain poorly studied, including the spatial distribution and habitat associations of nearshore fish species. This study used data collected from Cape Mendocino State Marine Reserve (SMR), Ten Mile …

Habitats Of Mind: Dhamma, The World, And Mindful Activism, Michael L. Masinter

Cal Poly Humboldt theses and projects

As a Buddhist, teacher, and a graduate student, coming to know the conflicts and misconceptions that stem from partial views and experiences, I have found it difficult to locate where to stand and how to engage. Buddhist teaching and practice (Buddhadhamma) offers a pragmatic approach to an overarching series of questions and a method of practice designed to address them: What is suffering, its origin, its cessation, and the way leading to its cessation? These are the Ariya-sacca, the four noble truths (or four ennobling realities), which can be applied to the arising of suffering anywhere in nature—whether internal (mind/culture) …

Foraging Habitat Of Pileated Woodpeckers In Relation To A Managed Landscape On The Hoopa Valley Reservation, Northwestern California, Dawn Michelle Blake

Cal Poly Humboldt theses and projects

The Pileated woodpecker (Dryocopus pileatus) is associated with older forest stages—larger diameter trees and snags for roosting, nesting and foraging, but they also use managed forests. The Hoopa Reservation is approximately 37,000 ha of mostly forested area with an array of seral stages. The Hoopa Tribe manages timber, and explicitly provides habitat for woodpeckers according to the Tribe’s Forest Management Plan (FMP). No formal study has assessed woodpecker habitat at Hoopa, and habitat has not been well described in this region. I captured eleven woodpeckers and outfitted them with transmitters between 2009 and 2014, and I used resource …

The Historical Evaluation And Significance Of The Old Joerger Ranch, Martis Valley, California, Hope Caroline Schear

Cal Poly Humboldt theses and projects

United States history is full of adventure and pioneering but building the regional histories of the nation allows one to dig deeper into what it took to make this country develop socially and economically. In the mid 1800’s California experienced a boom like never before. In 1848, mill workers found gold at Sutter’s Mill in Coloma, California, which led to a huge influx of people and population spike that changed California forever. Once the Gold Rush subsided, agriculture replaced gold in California as a wealth generator. Early settlers discovered that the mild climate of the region allows a wide variety …

Differential Predictors Of Opposition To Same-Sex Marriage And Sexual Prejudice, Latishia E Y Jett-Dias

Cal Poly Humboldt theses and projects

This study investigated attitudes toward same-sex marriage and its beneficiaries from the frameworks of social dominance orientation (SDO) and political conservatism. Unlike past research that focused mainly on sexual prejudice, the current paper explicitly examined both opposition to same-sex marriage and sexual prejudice. Additionally, the current study explored subcomponents of SDO (i.e., opposition to equality [OEQ] and group-based dominance [GBD]). Study One examined relationships and predictive difference between attitudes toward same-sex marriage and its beneficiaries before California legalized same-sex marriage. Study Two addressed attitudes before and recently after California legalized same-sex marriage. OEQ, GBD, and conservatism predicted opposition to same-sex …

The Performance Of 2d And 3d Tsunami Evacuation Maps: A Case Study For Seaside, Oregon, Aaron M. Taveras

Cal Poly Humboldt theses and projects

Tsunami evacuation maps are intended to inform the public about the geographic extent of the hazard and where to evacuate, but these maps can be difficult to interpret for people unfamiliar with cartographic semiology. This study focuses on the performance of tsunami evacuation maps and how the tsunami hazard is represented cartographically, as at-risk communities must be able to act quickly, and effectively understand tsunami maps to remain aware of the hazard and adequately evacuate. This study investigated the use of static three-dimensional (3D) perspective maps and travel time to safety representation (shown using point markers and choropleth symbology), as …

Jeweled Spider Flies (Eulonchus Tristis) Are Important Pollinators Of Iris Bracteata, A Rare Siskiyou Mountain Endemic, Jean-Paul E. Ponte

Cal Poly Humboldt theses and projects

Little is known about the pollination biology of the Pacific Coast Irises (Iris: series Californicae, hereafter PCI), especially who visits and pollinates their flowers. In general, Iris flowers are considered bee-pollinated, however, flies in the genus Eulonchus (Acroceridae) are known to visit some PCI members. Therefore, I assessed the relative importance of Eulonchus and other insect visitors to the pollination of a rare PCI species native to the Siskiyou Mountains, I. bracteata.

Methods. I quantified pollinator importance for all flower visitors at sites in northern California and southern Oregon as the product of average visit rate and …

Informal Science In The Classroom: How Informal And Formal Educational Institutions Support Science Instruction, Kellie Michelle Crawford

EWU Masters Thesis Collection

Science education has seen a major overhaul with the implementation of ideas from the NRC’s (2012) report, A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas. At the same time, we have seen a rise in the number of formal educational facilities partnering with informal facilities to bring these practices to students. This study explored the effect these blended approaches had on both student attitudes and their achievement in science content areas. To do this, surveys were designed to assess these areas in upper elementary students participating in a one-year blended science program. First, the literature was …

Using Instructed Response Times To Compare Inattentive Responding Across Paper And Online Modalities: Measuring Research Participant Inattention, Olivia B. Brooks

EWU Masters Thesis Collection

It is important to examine the equivalence of paper and online data collection methods across several domains. The current study compared paper versus online modalities from a data quality standpoint, with a specific focus on inattentive (i.e., careless) responding by using an easily-implemented method to capture participants’ careless responses: interspersing instructed response items (e.g., “Please select option 3, ‘Strongly disagree,’”) throughout a collection of 15 established measures. A between-subjects design compared the percentage of instructed response items missed (hence, inattentive responses) across three conditions: 1) lab paper, 2) lab online, and 3) non-lab online. The non-lab online condition was predicted …

Composites For Hydraulic Structures: A Review, Yingxiang Lu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Composites for hydraulic structures: a review Composites have evolved over the years and are making major in-roads into the marine, aviation and other industries where corrosions and self-weight are the major impediments to advancing the state-of-the-art. Civil Works engineers have been reluctant to make use of these composite advantages, partially because of the absence of well documented success stories, accepted design and construction practices or specifications, and limited understanding of composites, higher initial costs and others. A few navigational structures using FRP composites have been designed, manufactured and installed in the United States of America and Netherlands, recently. US Army …

A Descriptive Analysis Of The Fourth Amendment And The Third-Party Doctrine In The Digital Age, Lawrence J. Trautman, Peter Ormerod

Faculty Publications

There are few areas of constitutional law that raise scholars’ ire and trouble jurists like the Fourth Amendment’s third-party doctrine. Making sense of the Court’s distinctions between content and metadata and between personal communications and business records was already difficult with physical documents and analog technologies. But the proliferation of digital technologies has rendered obsolete the factual predicates underpinning those distinctions, and courts have struggled mightily with adapting third-party rules forged over thirty years ago to new technologies.

At the same time, the Supreme Court has become more explicit in fashioning distinct Fourth Amendment rules for digital 74 ALB. L.J. …

Monitoring The Influx Of Marine Derived Nitrogen And Characterizing Soil Food Webs Of Riparian Zones Of The Elwha River Watershed, Wa, Usa., Wendal R.H. Kane

EWU Masters Thesis Collection

Nitrogen is often the most limiting nutrient to productivity in terrestrial ecosystems, and can have large effects on ecosystem processes. Two sources of nitrogen to Pacific Northwest riparian areas are marine derived nitrogen (MDN) via anadromous pacific salmon and symbiotic nitrogen fixation via Alnus rubra. The recent removal of two large dams on the Elwha River, WA, opened up ~60 km of previously inaccessible river habitat for pacific salmon. I used naturally abundant stable nitrogen isotopes (denoted as ‰ δ15N) to establish baseline data to monitor the influx of MDN to riparian zones of Elwha River tributaries, post dam removal. …

The Bi-Directional Relationship Between Gut Microbiota And Autoimmunity, Trevor O. Kirby

EWU Masters Thesis Collection

Humans serve as a major reservoir for a vast number of microbiota. These microbes have evolved symbiotic relationships with humans due to their close proximity with their host. As a result, the immune system adapts to the microbiota thus modulating immunological function. Autoimmunity is a state in which there are aberrant immune responses produced against host tissue. Intestinal bacteria are directly impacted by instances of inflammation brought on by autoimmunity. The complicated nature between autoimmunity and bacterial modulation demonstrates a bi-directional relationship. Here, we utilize experimental autoimmune encephalomyelitis, a model for multiple sclerosis, to explore the bi-directional relationship that disease …
