Evaluating The Spatial Trends And Statistical Determinants Of Residential Solar Uptake In Washington State, Caleb Michael Valko Jan 2021

Evaluating The Spatial Trends And Statistical Determinants Of Residential Solar Uptake In Washington State, Caleb Michael Valko

All Master's Theses

Washington State’s Clean Energy Transformation Act and other state and federal policies encouraging solar power make Washington a ripe candidate to examine growth, trends, and potential determinants or barriers to residential solar uptake. In this thesis, residential solar is cumulatively and annually mapped by county (2000-2019) and Census tract (2017-2019) across the state to identify trends over time and space. Each variable (income, age, households, race, education, solar insolation, cost of solar per watt) was isolated individually to analyze the relationship (if any) to the dependent variable (i.e., residential solar installations). The covariates are then combined into a multiple regression …

The Value Of Urban Flood Modeling, B. R. Rosenweig, P. Herreros Cantis, Y. Kim, A. Cohn, K. Grove, J. Brock, Heejun Chang, Multiple Additional Authors

Geography Faculty Publications and Presentations

Floods are important disturbances to urban socio-eco-technical systems and their meteorological drivers are projected to increase through the century due to global climate change. Urban flood models are numerical models that have the capability of representing the features of urban ecosystems and the mechanisms of flooding that impact them. They have the potential to play a critical role in flood risk assessment, operational response, and resilience planning, but existing models remain limited in their capability to represent integrated flooding processes in urban areas and provide the credible quantitative information needed to support risk assessment and resilience practice. Research to advance …


Orienting New International College Students During A Global Pandemic: Spatiality’S Contributions To Staff Work Practices, Thomas W. Teague Jr. Jan 2021

Orienting New International College Students During A Global Pandemic: Spatiality’S Contributions To Staff Work Practices, Thomas W. Teague Jr.

Theses and Dissertations--Educational Policy Studies and Evaluation

U.S. colleges must increasingly respond to a wide range of complex forces and simultaneously fulfill their missions and support students. To address many of these forces, some have turned to internationalization efforts like recruiting and enrolling international students. In light of these efforts, critics have called for institutions to better, more appropriately support these students, given their challenges and needs. This call has amplified during the recent COVID-19 global health pandemic.

Traditional student support services tend to center around Tinto’s Theory of Student Departure. Examples of support programming are frequently shared, yet rarely detail how institutional staff actually perform them …

Effects Of Training Set Size On Supervised Machine-Learning Land-Cover Classification Of Large-Area High-Resolution Remotely Sensed Data, Christopher A. Ramezan, Timothy A. Warner, Aaron E. Maxwell, Bradley S. Price

Faculty & Staff Scholarship

The size of the training data set is a major determinant of classification accuracy. Neverthe- less, the collection of a large training data set for supervised classifiers can be a challenge, especially for studies covering a large area, which may be typical of many real-world applied projects. This work investigates how variations in training set size, ranging from a large sample size (n = 10,000) to a very small sample size (n = 40), affect the performance of six supervised machine-learning algo- rithms applied to classify large-area high-spatial-resolution (HR) (1–5 m) remotely sensed data within the context of a geographic …

Sexual And Place-Based Identity: A Life Course Analysis Of Lgbtq+ Undergraduate Understandings Of Climate Change In Appalachia, Brandon Anthony Rothrock

Graduate Theses, Dissertations, and Problem Reports (ETD)

LGBTQ+ persons face heightened vulnerability to climate change-induced disasters due to their sexual orientation, gender identity, and gender expression. Yet, there are limited studies that examine how LGBTQ+ students, particularly in a higher-education setting, understand climate change in relation to their sexuality. With a majority of studies on LGBTQ+ persons and climate change focusing on LGBTQ+ experience during and after disaster, there is a gap in understanding LGBTQ+ perceptions of climate change in the day-to-day. Particularly in Appalachia, a region characterized by a strong place-attachment to and a collective identity with the natural environment, studies of marginalized groups’ perceptions of …

This paper is part of a series that is a product of a synthesis effort of the U.S. National Science Foundation’s Long Term Ecological Research (LTER) network. This effort revealed that each LTER site had at least one compelling scientific case study about “what their site would look like” in 50 or 100 yr. As the site results were prepared, themes emerged, and the case …


Overcoming Loneliness: First-Generation Slavic Immigrants' Experience With Loneliness In The Inland Northwest, Charles C. Crook Jan 2021

Overcoming Loneliness: First-Generation Slavic Immigrants' Experience With Loneliness In The Inland Northwest, Charles C. Crook

EWU Masters Thesis Collection

The plight of loneliness has caused devastation to many social and cultural groups’ well-being. Scholars have analyzed and documented its adverse health such as suicide (Stravynski and Boyer 2001), Alzheimer’s disease (Wilson et al. 2007), depression (Erzen and Çikrikci 2018), immune system complications (Hawkley and Cacioppo 2003), and cardiovascular complications (Hawley and Cacioppo 2003). Some compare its health impacts to smoking 15 cigarettes a day (Health Resources and Services Administration 2019), while others emphasize how loneliness compels people to internet addiction (Ayas and Horzum 2013) and alcohol abuse (Åkerlind and Hörnquist 1992). Among the most susceptible populations to loneliness are …

Encoding A Categorical Independent Variable For Input To Terrset’S Multi-Layer Perceptron, Emily Evenden, Robert Gilmore Pontius Jan 2021

Encoding A Categorical Independent Variable For Input To Terrset’S Multi-Layer Perceptron, Emily Evenden, Robert Gilmore Pontius

Geography

The profession debates how to encode a categorical variable for input to machine learning algorithms, such as neural networks. A conventional approach is to convert a categorical variable into a collection of binary variables, which causes a burdensome number of correlated variables. TerrSet’s Land Change Modeler proposes encoding a categorical variable onto the continuous closed interval from 0 to 1 based on each category’s Population Evidence Likelihood (PEL) for input to the Multi-Layer Perceptron, which is a type of neural network. We designed examples to test the wisdom of these encodings. The results show that encoding a categorical variable based …


Debtor Spaces: Austerity, Space, And Dispossession In Michigan’S Emergency Management System, Melissa Heil Jan 2021

Debtor Spaces: Austerity, Space, And Dispossession In Michigan’S Emergency Management System, Melissa Heil

Faculty Publications - Geography, Geology, and the Environment

In recent years, debt has become a major focus of geographic research as debt relations have become increasingly central to today’s financialized capitalist economy. This paper bridges two aspects of the debt literature: (1) the emergent literature on debt spatiality, which argues that space plays an active role in the creation and maintenance of debt relations, and (2) the broader literature examining processes of debt-driven dispossession (e.g., foreclosure, eviction, austerity, etc.). Recent literature in geography, led by Harker’s work on debt spaces, has argued that debt should not only be understood as a temporal relation (a promise of future labor) …


Volunteer Urban Environmental Stewardship, Emotional Economies Of Care, And Productive Power In Philadelphia, Alec Foster Jan 2021

Volunteer Urban Environmental Stewardship, Emotional Economies Of Care, And Productive Power In Philadelphia, Alec Foster

Faculty Publications - Geography, Geology, and the Environment

Recent efforts to increase urban forests and greenspaces rely on the volunteer labor of individuals and environmental nonprofits. The estimation of market values has often justified urban greening. These neoliberal approaches to urban environmental governance have been heavily critiqued, revealing the uneven power relationships and urban environments that result. This paper aims to move beyond such critiques by exploring how the reproduction of urban nature can be valued outside of the market. Fieldwork with volunteers participating in environmental stewardship in Philadelphia revealed their participation was motivated by intense emotional attachments to their neighborhoods, other participants, and nonhuman others, leading me …


Hmong In The Twin Cities: Diaspora Experiences And Personal Identities, Anisha Rajbhandary Jan 2021

Hmong In The Twin Cities: Diaspora Experiences And Personal Identities, Anisha Rajbhandary

Geography Honors Projects

Asian Americans as a whole have been portrayed as “model minorities” due to their higher degree of socioeconomic success compared to the average population. However, this “model minority” stereotype primarily based upon the voluntary immigration experiences of East and South Asians with greater socio-economic resources, hardly accounts for the immigration experiences of other Asian groups such as Hmong Americans. Utilizing extensive literature review, first person interviews and collected survey data, this paper explores Hmong diaspora and identity in the Twin Cities of Minnesota, analyzing how Hmong Americans reconcile with the stereotypes set for Asian “model minorities” and construct their own …


Can Stable Isotopes From Tree Rings Improve Our Understanding Of Past Variability In The Southern Annular Mode?, Zachary Grzywacz Jan 2021

Can Stable Isotopes From Tree Rings Improve Our Understanding Of Past Variability In The Southern Annular Mode?, Zachary Grzywacz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Few annually dated stable isotope records exist across Oceania. In mid- to high-latitude locations in South America, tree-ring stable isotopes provide information about past climate dynamics such as the Southern Annular Mode (SAM). The SAM drives latitudinal shifts in Southern Hemisphere westerly winds, influencing temperature and moisture delivery across the mid- to high-latitudes, including Tasmania. Combinations of paleoclimate proxies from across the Southern Ocean might provide insight into dynamic processes like the SAM that are difficult to measure with a single proxy. Measuring stable carbon and oxygen isotope ratios from tree rings in Tasmania could provide complementary data to contribute …

Assessing Synthetic Aperture Radar (Sar)-Derived Temporal Patterns And Digital Terrain Data For Palustrine Wetland Mapping, Jaimee L. Pyron

Graduate Theses, Dissertations, and Problem Reports (ETD)

Palustrine wetland systems are important ecosystems and provide numerous ecosystems services to support society. Unfortunately, they remain under constant threat of devastation due to land use practices and global climate change, which underscores the need to identify, map, and monitor these landscape features. This study explores harmonic coefficients and seasonal median values derived from Sentinel-1 synthetic aperture radar (SAR) data, as well as digital elevation model (DEM)-derived terrain variables, to predict palustrine wetland locations in the Vermont counties of Bennington, Chittenden, and Essex. Support vector machine (SVM) and random forest (RF) machine learning models were used with various combinations of …


Effects Of States’ Laws On Youth Physical Activity Participation And Obesity Prevalence, Chae Young Chang Jan 2021

Effects Of States’ Laws On Youth Physical Activity Participation And Obesity Prevalence, Chae Young Chang

Midwest Social Sciences Journal

The alarming prevalence of obesity and lack of physical activity among adolescents led to immediate policy action to address these concerns. Accordingly, many states introduced and enacted their own legislation to encourage physical activity in schools. Few studies have explored the effectiveness of the new legislation, however, especially at the state level. To answer the fundamental question of whether policy is effective and to describe the varying effects of state obesity policies, this study analyzed the Youth Risk Behavior Surveillance System from 2007 to 2017. Using the difference-in-differences method, this study found that legislative efforts to encourage physical activity had …


Profitable Retail Customer Identification Based On A Combined Prediction Strategy Of Customer Lifetime Value, Yinglu Sun, Dong Cheng, Subir Bandyopadhyay, Wei Xue Jan 2021

Profitable Retail Customer Identification Based On A Combined Prediction Strategy Of Customer Lifetime Value, Yinglu Sun, Dong Cheng, Subir Bandyopadhyay, Wei Xue

Midwest Social Sciences Journal

As a fundamental concept of customer relationship management, customer lifetime value (CLV) serves as a crucial metric to identify profitable retail customers. Various methods are available to predict CLV in different contexts. With the development of consumer big data, modern statistics and machine learning algorithms have been gradually adopted in CLV modeling. We introduce two machine learning algorithms—the gradient boosting decision tree (GBDT) and the random forest (RF)—in retail customer CLV modeling and compare their predictive performance with two classical models—the Pareto/NBD (HB) and the Pareto/GGG. To ensure CLV prediction and customer identification robustness, we combined the predictions of the …

A Systematic Method For Measuring Gentrification Using Building Permits Data: A Washington D.C Case Study, Andey Fomil

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gentrification can significantly alter the socioeconomic, demographic, and commercial aspects of a city. It is a complex process that transforms the characteristics of entire neighborhoods, modifying not only the observable physical aspects, but also the community structure. Traditional quantitative gentrification measurement approaches assess the process through analysis of Census demographic indicators coupled with field visit analysis of the physical built environment. This study proposes a new gentrification measuring approach that combines traditional Census indicators with a new indicator in the form of City Building Permits. Two GIS spatial analysis techniques are utilized to evaluate the effectiveness and accuracy of the …
