Residential Solar In Washington State, Sam Pfeifer Jan 2018

Residential Solar In Washington State, Sam Pfeifer

All Master's Theses

Electricity generated through residential solar provides a low carbon source of electricity. However, diffusion of residential solar remains low across the United States. Growing this diffusion takes an understanding of localized uptake trends, which can focus policy and business efforts to help increase residential solar market penetration. This is the first research to investigate residential solar uptake in Washington State and to examine environmental education as a potential driver of residential solar uptake. Through a snapshot analysis which considers environmental, economic, education, and cultural variables the present research fills this gap. Triangulated results include mapping of variables, ordinary-least squares multiple …

Enrichment Assessment For Geriatric African Old World Monkeys Under Human Care, Amanda E. Osborne Jan 2018

Enrichment Assessment For Geriatric African Old World Monkeys Under Human Care, Amanda E. Osborne

All Master's Theses

I proposed a study that determines whether enrichment regimes used for geriatric African Old World monkeys living under human care are effectively eliciting affiliative and active behaviors. I wanted to determine if alternating enrichment types used by the zoo staff were eliciting different social behaviors and locomotion in non-human primates based on different factors including ages, species, and sexes. My data collection took place at the Association of Zoos and Aquarium (AZA) accredited, Oregon Zoo in Portland, Oregon. I conducted my research from 11 June to 5 August 2017. I collected data from eight individuals of varying ages from three …

Effects Of Pre-Exercise Ice Slurry Ingestion On Physiological And Perceptual Measures In Athletes With Spinal Cord Injuries, Alexis Moore, Kelly Pritchett, Robert Pritchett, Elizabeth Broad Jan 2018

Effects Of Pre-Exercise Ice Slurry Ingestion On Physiological And Perceptual Measures In Athletes With Spinal Cord Injuries, Alexis Moore, Kelly Pritchett, Robert Pritchett, Elizabeth Broad

All Master's Theses

Athletes with spinal cord injuries (SCI) have an impaired ability to thermoregulate during exercise, leading to an increased core temperature (Tcore) due to a decrease in sweat response. Elevated core temperature may result in premature onset of fatigue and decreased athletic performance. Therefore, precooling techniques that decrease Tcore before exercise may increase the storage capacity for metabolic heat production, thereby improving exercise performance. The purpose of this study was to investigate the effects of pre-exercise ice slurry ingestion as a precooling method in elite athletes with SCI during a match simulation. Employing a field-based, counterbalanced-design, subjects were …

Tsunami Excitation Estimation From Real-Time Gnss, Catherine Jeffries Jan 2018

Tsunami Excitation Estimation From Real-Time Gnss, Catherine Jeffries

All Master's Theses

Tsunami early warning systems currently comprise modeling of observations from the global seismic network, deep-ocean DART buoys, and a global distribution of tide gauges. While these tools work well for tsunamis traveling teleseismic distances, saturation of seismic magnitude estimation in the near field can result in significant underestimation of tsunami excitation for local warning (Wang et al., 2012). Moreover, DART buoy and tide gauge observations cannot be used to rectify the underestimation in the available time, typically 10-20 minutes, before local runup occurs. Real-time GNSS measurements of coseismic offsets may be used to estimate finite faulting within 1-2 minutes and, …

Characterization Of Coacervate Systems Using Redox Sensitive Dyes, Caleb Kaiser Jan 2018

Characterization Of Coacervate Systems Using Redox Sensitive Dyes, Caleb Kaiser

All Master's Theses

Coacervates are systems that spontaneously form when two oppositely charged polyelectrolytes are mixed in a concentrated salt solution. When coacervates form, a biphasic equilibrium occurs in the sample with two phases present in the solution. The two phases are described as the dense phase and the lean phase, named after the amount of polyelectrolyte material in each phase. Coacervates have been topics of interest to researchers in a variety of fields including biomedical applications, drug delivery devices, and more. This thesis worked towards the characterization of coacervate systems on the molecular level by investigating the interaction of the polyelectrolytes and …

Single And Pair Housed Chacma Baboons’ (Papio Ursinus) Response To Caregivers’ Use Of Species-Specific Behavior, Josefine Holm Jan 2018

Single And Pair Housed Chacma Baboons’ (Papio Ursinus) Response To Caregivers’ Use Of Species-Specific Behavior, Josefine Holm

All Master's Theses

Most captive primates suffer from stereotypical or abnormal behavior which can be reduced by implementing enrichment protocols. There is, however, often spatial or economic limitations to facilities’ enrichment programs, and implementing the most beneficial and cost-effective enrichment is therefore crucial to ensure the best welfare for captive primates. Social enrichment has been designated as the most effective type of enrichment, but often captive primates cannot be housed in social groups. Through this study, I wanted to determine if species-specific behavioral interactions between human caregivers and captive chacma baboons (Papio ursinus)would alter the baboons’ behaviors, and if these interactions could …

Spike-Based Classification Of Uci Datasets With Multi-Layer Resume-Like Tempotron, Sami Abdul-Wahid Jan 2018

Spike-Based Classification Of Uci Datasets With Multi-Layer Resume-Like Tempotron, Sami Abdul-Wahid

All Master's Theses

Spiking neurons are a class of neuron models that represent information in timed sequences called ``spikes.'' Though predominantly used in neuro-scientific investigations, spiking neural networks (SNN) can be applied to machine learning problems such as classification and regression. SNN are computationally more powerful per neuron than traditional neural networks. Though training time is slow on general purpose computers, spike-based hardware implementations are faster and have shown capability for ultra-low power consumption. Additionally, various SNN training algorithms have achieved comparable performance with the State of the Art on the Fisher Iris dataset. Our main contribution is a software implementation of the …

Internal Composition, Structure, And Hydrological Significance Of Rock Glaciers In The Eastern Cascades, Washington, Adam Riffle Jan 2018

Internal Composition, Structure, And Hydrological Significance Of Rock Glaciers In The Eastern Cascades, Washington, Adam Riffle

All Master's Theses

Low summer river base flow places a strain on natural and economic resources of the Eastern Cascades. A major contributor to stream flow in this region is snow pack which has declined over the past few decades because of a warming climate. In addition, glacial runoff, which contributes significantly to base flow in summer dry periods, will diminish from glacial recession. However, rock glaciers, because their internal ice (i.e., permafrost) is insulated by an outer debris layer, react slowly to climate change, thus acting as sinks for ice and liquid water storage in mountain environments. This study utilized ground penetrating …

Slip Estimation From Real-Time Gps In Cascadia, Jesse Senko Jan 2018

Slip Estimation From Real-Time Gps In Cascadia, Jesse Senko

All Master's Theses

Current systems for rapidly characterizing earthquakes are based on seismic, teleseismic, and Deep-ocean Assessment and Reporting of Tsunami (DART) buoy data. These systems have significant limitations that hinder them from making rapid and accurate assessments of large earthquakes used for local tsunami warnings where run-up can occur minutes after the earthquake. Seismic and teleseismic networks saturate around Mw 7.0. Tsunami waves take tens of minutes to reach the buoys, so rapid assessment is impossible. GPS overcomes these limitations for large earthquakes. GPS does not saturate, and the offsets being detected occur very quickly after an earthquake. This thesis develops …

Quantifying Crustal Assimilation In Historical To Recent (1329-2005) Lavas At Mt. Etna, Italy: Insights From Thermodynamic Modeling, Marie Takach Jan 2018

Quantifying Crustal Assimilation In Historical To Recent (1329-2005) Lavas At Mt. Etna, Italy: Insights From Thermodynamic Modeling, Marie Takach

All Master's Theses

The nearly continuous volcanic eruption record at Mt. Etna dating back approximately 700 years provides an excellent opportunity to investigate the geochemical evolution of a highly active volcano. Of particular interest is elucidating the cause of a selective enrichment in alkali elements (K, Rb, Cs) and 87Sr/86Sr. This alkali enrichment trend, which began in the 17th century and accelerated after 1971, was accompanied by an increase in the volume, frequency, and explosivity of eruptions. To explain this enrichment, two major arguments are invoked: (1) crustal contributions (e.g., assimilation of the sedimentary basement), and (2) changes in …

Embodying The Hyphen: An Ethnography On Korean Adoptees, Barbara Hammersberg Jan 2018

Embodying The Hyphen: An Ethnography On Korean Adoptees, Barbara Hammersberg

All Master's Theses

An estimated 150, 000 Korean children have grown up in culturally and racially different homes in the United States and other countries since the increase of transnational adoption in 1953. Due to the large number of Korean adoptees living in the U.S. the potential for ethnographic research is profound. Past studies have favored adoptive parents’ perspectives over that of Korean adoptees. This study aims to address that limitation in hopes of contributing to the growing trend of Korean- adoption ethnographic research led by Korean adoptees. Drawing on semi-structured interviews with six Korean-American adoptees living in the Seattle metropolitan area in …

An Examination Of The In-Group Hypothesis In Facial Expression Inferences Using American And Indian Samples, Scott Lehrman Jan 2018

An Examination Of The In-Group Hypothesis In Facial Expression Inferences Using American And Indian Samples, Scott Lehrman

All Master's Theses

The relationship between culture and evaluations of facial expressions were assessed using American and Indian participants. Based on Ekman (1972) and others’ (cf. Elfenbein & Ambady, 2002) research that supports general cross-cultural agreement of facial expression evaluation, it was hypothesized that participants will be able to accurately evaluate a smiling face as happy and a scowling face as angry and that American participants would be more accurate overall due to the In-Group Hypothesis (Elfenbein & Ambady, 2002). Results showed that both cultures were able to accurately assess both facial expressions, although American participants had stronger evaluations across personality traits.

Sex Differences In Glycosylated Hemoglobin In Mauritian Origin Long-Tailed Macaques (Macaca Fascicularis), Ricardo A. Fernandes Jan 2018

Sex Differences In Glycosylated Hemoglobin In Mauritian Origin Long-Tailed Macaques (Macaca Fascicularis), Ricardo A. Fernandes

All Master's Theses

Diabetes is a common metabolic condition that affects the body’s ability to maintain normal glycemic control. This disease process can occur in primates. Long-tailed macaques (Macaca fascicularis) range throughout Southeast Asia and were introduced to Mauritius approximately 400 years ago. This genetically unique population has been the source of a large proportion of captive individuals used in research and macaques are the preferred animal model for diabetic research. Additionally, long-tailed macaques are successful in exploiting habitat overlapping with humans. This urbanization results in changes in the normal diet of these animals which can contribute to poor health outcomes …

Comparing Mothers’ And Fathers’ Helicopter Parenting As Predictors Of Self-Efficacy Among Emerging Adults In College, Jineui Kim Jan 2018

Comparing Mothers’ And Fathers’ Helicopter Parenting As Predictors Of Self-Efficacy Among Emerging Adults In College, Jineui Kim

All Master's Theses

This study examined the association between helicopter parenting and self-efficacy among emerging adults in college. While some existing research revealed that emerging adults could benefit from helicopter parenting, previous studies identified a wide range of negative outcomes of helicopter parenting on emerging adult’s psychological well-being. Also, previous research has shown that mothers and fathers play different roles in parenting. This study adds to understanding of this phenomenon by comparing the salience of mothers’ and fathers’ helicopter parenting as a predictor of self-efficacy among emerging adults in college. Data were collected from 175 participants between the ages of 18-24 by using …

Two Post-Glacial Sagebrush Steppe Fire Records At The Wildland-Urban Interface, Eastern Cascades, Washington, Dusty Pilkington Jan 2018

Two Post-Glacial Sagebrush Steppe Fire Records At The Wildland-Urban Interface, Eastern Cascades, Washington, Dusty Pilkington

All Master's Theses

Recent increases in large fires in the rapidly developing wildland-urban interface (WUI) areas of central Washington, where development intermixes with wildland fuels, contribute to federal firefighting costs exceeding of $1 billion annually. In addition, cheatgrass (Bromus tectorum) invasion and anthropogenic-caused warming shorten fire return intervals while lengthening fire seasons. These climatic, ecological, economic, and social factors combine with fuel accumulation resulting from historic fire suppression to threaten lives and property in the WUI. To plan for safe growth in WUI areas, long-term fire histories are needed to expand understanding of past fire regimes in an understudied ecosystem, sagebrush …

Advances In The Hyperspectral Imaging Microscope Spectrometer Method, And Application For Measuring The Spectral Reflectance Of Light Absorbing Aerosols From The South Cascades, Colorado Rockies, And Iceland, Melanie Swick Jan 2018

Advances In The Hyperspectral Imaging Microscope Spectrometer Method, And Application For Measuring The Spectral Reflectance Of Light Absorbing Aerosols From The South Cascades, Colorado Rockies, And Iceland, Melanie Swick

All Master's Theses

Snow and glaciers are receding at a global scale. Warming temperatures are often identified as the dominant cause of this decline; however, deposition of light absorbing aerosols (LAA), including black carbon, mineral dust and organics onto snow and glacier surfaces can be an even larger driver of melt in some regions (Skiles et al., 2012). Attempts to partition the relative contribution of different types of LAA to snow and glacier melt has been limited by the uncertainties in the LAA optical properties (Kaspari et al., 2014). A new hyperspectral imaging microscope spectrometer (HIMS) method was recently developed to measure LAA …

Antibody Dependent Enhancement Of Visceral Leishmaniasis, Alan K. Mcnolty Jan 2018

Antibody Dependent Enhancement Of Visceral Leishmaniasis, Alan K. Mcnolty

All Master's Theses

Leishmaniasis is a parasitic disease caused by protozoans of the genus Leishmania. This vector-born disease, transmitted by biting phlebotomine sandflies, typically manifests in one of three ways. The cutaneous form of the disease is characterized by localized lesions of the skin and is by far the most common manifestation. The visceral form of the disease is caused by parasitic infiltration of internal organs, particularly the spleen, liver, and bone marrow. The mucocutaneous form is caused by parasitic infection of the mucosa in the nose or mouth. While cutaneous leishmaniasis (CL) is often self-healing, visceral leishmaniasis (VL) is fatal if …

Geomorphic Consequences Of Hydroelectricity And Transportation Development Near Celilo Falls, Lower Mid-Columbia River, Washington, Noah I. Oliver Jan 2018

Geomorphic Consequences Of Hydroelectricity And Transportation Development Near Celilo Falls, Lower Mid-Columbia River, Washington, Noah I. Oliver

All Master's Theses

Along the Columbia River, hundreds of miles of transportation infrastructure and over sixty hydroelectric dams have been constructed. This altered a rich cultural landscape with evidence of 10,000 years of continuous occupation. Researchers have attempted to understand the impacts of anthropogenic factors on the Columbia River, focusing on the riverine environment. However, the effect of transportation and hydroelectricity developments to eolian landforms on the floodplains and adjoining slopes have not been studied. Focusing on 2,800 acres near Celilo Falls, this study 1) establishes a baseline condition of eolian landforms from 1805 to 1900; 2) conducts an air photo increment analysis …
