This paper provides the necessary assessment to understand tourism's role and contribution to the Saudi economy and to determine whether the industry's growth is on the right track. Also, this paper also …

Automated Tree Mortality Detection Using Ubiquitously Available Public Data, Michael T. Huggins

Master's Theses

Understanding the dynamic interplay between fire severity, topography, and tree mortality, is crucial for predicting future forest dynamics and enhancing resilience against climate change-induced wildfire regimes. This thesis develops a multi-sensor approach for automated estimation of tree mortality, then applies it to examine trends in tree mortality over a six-year period across a fire affected study site in the Trinity River basin in Northern California. The Random Forest model uses publicly available USGS 3D Elevation Program Lidar (3DEP) and NAIP imagery as inputs and is likely to be easily adaptable to other landscapes. The model had a Receiver Operating Characteristic …

An Exploratory Framework For Benchmarking Vehicle Miles Traveled (Vmt) Estimates Associated With University Campuses, Troy Kawahara

Master's Theses

Although vehicle miles traveled (VMT) has become the standard for assessing transportation related impacts in California, some have concerns that many VMT estimates are not properly grounded or informed by real world data, potentially resulting in flawed estimates and impact assessments. This is especially true of special generators, like college and university campuses, which have complex travel patterns distinct from that of the general public. This thesis attempts to resolve a significant disparity observed between two credible VMT estimates for Cal Poly’s campus wide VMT. As part of a campus master planning effort, a VMT estimate was produced in 2019 …

Habitat Characterization Of American Badgers (Taxidea Taxus) Of Northern California, Mitchell Victoria

Master's Theses

American badgers (Taxidea taxus) are a semi fossorial mammal that lives in grassland and open prairie ecosystems as well as coastal prairies, agricultural fields, deserts, and deforested habitats. Many researchers have published work on badgers, but we still require more information on their ecology. The American badger is a semi fossorial, solitary, predatory mammal of grassland ecosystems. They are classified as mesopredators when compared to larger apex predators such as brown bears, wolves, and pumas. However, when larger carnivores are absent, Badgers become apex predators of their ecosystems. Los Vaqueros Watershed in Brentwood, California, was my study site because badgers …

Justice And Equity In Urban Water Allocations And Conservation Solutions: A Case Study Of Non-Traditional Housing Dwellers, Matthew J. Mangoni

Master's Theses

Access to water is a human right. With droughts becoming more frequent and severe, equitable and just access to fresh water is a critical concern for policymakers and regulators. Allocation-based (AB) water rates are used widely to incentivize conservation. Previous authors document benefits of this approach for single family homes (SFH) in urban areas. People living in homeowners’ associations (HOAs) or multi-family homes and renters – commonly grouped as non-traditional housing (NTH) tend to face barriers to understanding or controlling water use and costs. This thesis investigates the equity and effectiveness of 1) AB water rate structuring and 2) a …

The Watchmen In The Song Of Songs: An Intertextual Study, Gabriel Xavier Del Valle

Master's Theses

Problem

The watchmen are a shocking feature in the Song of Songs that have received limited exploration and research. Their dual nature in the Song of Songs is illustrated by their two responses to the women in the song; benign indifference illustrated in Song of Songs 3:1-5 and hostility exemplified in Song of Songs 5:2-8. This has led to a myriad of interpretations regarding their function and identity; however, none have been subject to a thorough examination. The watchmen have not been previously investigated as a potential metaphorical or symbolic representation of the brothers related to the woman in the …

Whose Woods These Are: Human-Environment Relationships Among Stakeholders Of South Mississippi's Longleaf Pine Ecosystem, Helen Greene

Master's Theses

Between 1870 and 1920, the longleaf pine belt of the southeastern United States experienced an extensive and unsustainable period of logging. In the years after the logging boom the landscape of the Southeast was reforested, but fire suppression and a preference among landowners for loblolly pine resulted in a dense and less resilient forest with reduced biodiversity. This research looks at the human geography of remnants of the longleaf pine ecosystem in South Mississippi and the nature of contemporary relationships between South Mississippi residents and this ecosystem.

In an effort to make sense of the complex relationships between people and …

Factors Affecting California Grassland Biodiversity: Two Case Studies, Nora Bales

Master's Theses

Biodiversity loss over the last century has been significant and is projected to increase. Biodiversity loss is accelerating due to climate change and habitat loss and degradation. Biodiversity supports key ecosystem services including pollination services, climate regulation, and water filtration. Biodiversity conservation is a top priority for land managers and researchers, however many ecological studies with practical applications lack a thorough understanding of the soil environment in their study system. We conducted two case studies integrating soil and plant data to answer management questions. The first case study investigated the relationship between a threatened plant, Hooveria purpurea var. purpurea and …

Characters toil with their psychological state within a shared and collective universe of the unknown. The characters found within A Minor Place deal with sensitive issues such as loss, isolation, and overcoming their difficulties. A Minor Place implements narratives to showcase a "minor” tonality and coloration and style to accompany this titular minor place.

War And Genocide In Darfur And Its Impact On Darfur Society, Hamid Elshareif

Master's Theses

The Darfur region in western Sudan has witnessed bloody revolutions and conflicts since the beginning of 2003. The Sudanese government recruited militias such as Janjaweed who killed and robbed the civilian people of Darfur. The Janjaweed practiced murder, rape, torture, the burning of villages, looting, and theft which amounted to what most people consider genocide. This genocide is being practiced against the indigenous African tribes in the western region of Sudan which is less developed and has been marginalized by the government in Khartoum. Reasons for this conflict are in question with many people seeing it as purely an Arab …

Mapping Effectiveness: Farm Mechanization Initiatives By Lumbini Province Of Nepal (Fiscal Year 2018/19), Ananda Phuyal

Master's Theses

An effective farm mechanization program should increase crop production and be profitable to the benefitting households. Increasing labor shortages and decreasing animal draft power in agriculture demanded farm mechanization to increase food productivity in Nepal. To increase crop yield, the Ministry of Land Management, Agriculture and Cooperative (MOLMAC) of Lumbini Province in Nepal distributed 1994 subsidized tools and machinery in Fiscal Year 2018. The farm mechanization program by the government was an ambitious program and was implemented without research to address the actual need of the geography. However, the program had a positive impact on the community. It is found …

Political Economy Of General Normative Force In The Paris Agreement, Jonah B. Jellesed

Master's Theses

The Paris Agreement revolutionizes international cooperation in addressing the urgent threat of climate change. However, its status as an emerging system of global climate governance remains largely unexplored. Drawing on HLA Hart's legal theory, we apply a straightforward test to determine its significance, revealing the Paris Agreement as evidence of a new international legal order. This has far-reaching implications, particularly in the realm of political economy. Unlike previous analyses that merely consider whether a state is a signatory to the agreement or not, our innovative approach delves deeper into countries' commitment. Our analysis shows high compliance levels among populations in …

Empirical Evidence For The Emergence Of Global General Normative Force In The Paris Agreement, Michael J. Nordquist

Master's Theses

The Paris Agreement presents a unique framework to address the pressing dangers of climate change. Given the magnitude of this global problem and our reliance on international treaties to counteract its adverse effects, it is imperative that we understand the evolving norms within this domain. To evaluate the extent to which the Paris Agreement serves as a second-order "rule of recognition" in the context of global climate governance, we utilize a straightforward test rooted in Hart's theory of the rule of law. Our approach entails enumerating the number of countries worldwide that have enacted laws explicitly referencing the Paris Agreement, …

The Grid That Binds: The Renewable Energy Transition In Germany, France, And Italy, Katherine A. Mason

Master's Theses

The current energy crisis and climate change are just some of the challenges that the European Union and its member states are forced to reckon with. The loss of fossil fuel supplies from Russia in the wake of the invasion of Ukraine forced the acceleration of the renewable energy transition and created a new set of problems to be addressed, namely the effectiveness of climate work that had already begun, and what the roadmap for the future would look like. Examining the history and infrastructure of Germany, France, and Italy presents insights into how this challenge can be met, and …

Abolition Ecologies And The Making Of Freedom As A Place In Bayview-Hunters Point, Spencer Daniel O'Hara

Master's Theses

In this paper, I critically explore the subjectivities of Hunters Point Naval Shipyard (HPNS), part of the largest redevelopment project in San Francisco since 1906. Applying an abolition ecologies framework, I ask what explains the duplicity of the Shipyard as a site of radioactive contamination and capital accumulation, and in the same time-space one that creates the conditions for radical place-making. Hunters Point Naval Shipyard is a former commercial and military shipyard located on a peninsula in southeastern San Francisco. Motivated by its desire for a major shipbuilding and repair facility to project maritime power in the Pacific, the Navy …

The Central American Minors Program: Advocating For Private Sponsorship, Magaly Velasco-Escobar

Master's Theses

Under this recommendation, minors would be interviewed by qualified officers at resettlement agencies in their home countries to assess credible fear, those deemed eligible but lacking an eligible relative would be referred for a private sponsorship pathway. Sponsors would be vetted and qualified using protocols currently in place by the Welcome Corps and Refugee Foster Care. Ideally, the Office of Refugee Resettlement (ORR) would coordinate between the private sponsors and overseas resettlement agencies, given they already do the work of vetting eligible sponsors for minors. ORR could create a program staffed with qualified individuals to coordinate this program or provide …

The Relationship Between Economic Complexity And Income Inequality: A Study On The United States Metropolitan Statistical Areas, Brooke Johnson

Master's Theses

This paper examines the relationship between income inequality and economic complexity, adding to the literature by providing new evidence for Metropolitan Statistical Areas (MSAs). With populations in cities rapidly increasing world-wide, settlement scaling research has revealed significant correlations between population size and various aspects of socio-economic wellbeing, including income inequality. Our study utilizes the Economic Complexity Index (ECI), a recently developed measure of economic development, to examine how changes in regional production structures influence inequality and shed light on the evolving nature of urban economies. By employing fixed effects OLS regression with clustered standard errors on both panel data from …

Post-Pandemic Digital Experiences & Attitudes Among Adult Immigrant Esol Learners, Lacey D. Goodloe

Master's Theses

This mixed-methods study considers the current reality of the “digital divide” as experienced by adult immigrant ESOL learners following the COVID-19 pandemic lockdown period. Although prior research often assumes foreign-born individuals to have lower rates of access, skills and motivation to engage with technology, or to lack it altogether, this study seeks to contribute a more realistic picture which encompasses the full diversity of digital experiences among the foreign-born population. The review of the literature first covers two levels of the digital divide that often evince socioeconomic disparities: primarily access, skills and usage; and more recently, attitudes and motivation. Then, …

Development And Economic Complexity Of Mexican Municipalities: Based On Their Energy Access And Gross Production., Angelica Gloria Velasco

Master's Theses

In 2015, Mexico ranked 22nd in the international list of ECI; Out of 136 countries, Mexico had a higher index than Netherlands and Denmark. How is this possible for a developing economy that in 2014 reached its highest inequality index at 50.3%? This research is focused on the behavior of the Economic Complexity Index when it interacts with income inequality (Gini Coefficient), the gross production and human development (which in this case is focused on access to basic services: education and electricity). In the first and second sections, this paper highlights the importance of the analysis at a municipality level …

Comparative Analysis Of Rhizosphere And Endosphere Microbiome Of Different Blueberry Species (Vaccinium Sp.), Niladri Bhowmik

Master's Theses

Blueberries are an important agricultural commodity in all over the United States. Due to its health benefits, there is a huge demand globally, thus expanding the industry. Breeding programs are essential to maintain such industries. Challenges that play a role in contemporary breeding programs are various biotic and abiotic stress factors. Studies have shown that microorganisms are recruited by plants to alleviate them during stressful conditions. Though blueberries have been cultivated for about 100 years, how the microbiome has been affected due to this is poorly understood. We hypothesized that interspecific crosses and artificial selection have significantly changed the microbiome …

Fourthspace: The Role Of Active Social Inclusion In The Workforce Entry Of Syrian Refugees In Scandinavia, Anisa Abeytia

Master's Theses

The 2015 displacement of Syrian refugees into Scandinavian countries provoked a refugee integration policy adjustment that focused on workforce and higher education entry. It is a policy approach that requires attention on barriers to workforce entry to ensure effective policy implementation. This article provides insight into the larger, often overlooked barriers of Eurocentrism and historical biases on refugee labor integration and provides policy solutions to reduce their impact. Active social inclusion (ASI) and Fourthspace are introduced as a framework to reduce biases to workforce entry and integration time barriers faced by Syrian refugees. ASI can provide mechanisms to increase access …

Heating Systems And Households’ Expenditure, Svitlana Holyk

Master's Theses

The heating energy expenditure has been frequently taken to the consideration across different studies of poverty reduction. However, there is an unresolved question related to understanding how households’ expenditures might be distinct due to the heating system characteristics. This research implements matching methods to investigate the causal effect of the heating system on households’ gas and electricity expenditure in Ukraine. The result indicates that there is a significant difference in the utility expenditure between the District heating system (DHS) and the Individual heating system (IHS) households. The inherited from the past the Soviet District heating system Model in Ukraine doesn’t …

New Insights Into The Paleovegetation Of The Ancient Underwater Forest Located In The Northern Gulf Of Mexico, Karla Lizarraga Garcia

Master's Theses

A well-preserved remnant of an ancient bald cypress forest (hereafter, Underwater Forest) constitutes the only known archive of a glacial refuge on the once exposed continental shelf of the Northern Gulf of Mexico. This forest existed around 41-72 yBP (MIS 3-5) according to the existing dating methods applied on previous studies. As the climate conditions and sea levels changed, the vegetation of this glacial refuge shifted from bald cypress forests to open marshes, altering the vegetation dynamics. The present research analyzed four new cores (21DF-5A, 21DF-5B, 15DF-6, and 16DF-3A), which provided additional insights into the vegetation that once existed in …

Analyzing Grassland Bird Song And Success: The Impact Of Landscape Characteristics On Western Meadowlarks (Sturnella Neglecta), Leah Crenshaw

Master's Theses

Grassland birds across both North America and globally are in rapid decline, and these population losses are primarily due to agricultural practices driving land-conversion and habitat degradation. While the effects of landscape characteristics like land cover, fragmentation, anthropogenic features, and land use on bird abundance and diversity are well-studied, the mechanisms behind those effects are poorly understood for many species. In our studies, we considered how individual condition and behavior may be underpinning some population losses in Western Meadowlarks (Sturnella neglecta). First, we investigated what natural, anthropogenic, and climatic landscape characteristics best predicted Western Meadowlark song structure. We used 421 …

Homelessness And Taphonomy: A Multidisciplinary Study, Chloë Angst

Master's Theses

In this thesis, I present multidisciplinary research applicable to deceased unhoused individuals in urban San José, California. I present the problem of homelessness through a “hybrid collectif,” a conceptual framework that encompasses the factors that drive homelessness in life and death. I use taphonomic methodology to examine the problem of homelessness in this urban region by experimentation with porcine carcasses in simulated death scenarios. I utilize total body score (TBS), accumulated degree days (ADD), and predictive entomological species identification to examine decomposition trends. I also introduce “human survival scavenging” as an agent of decomposition, provide an account of ecological succession …
