The Correlation Between Perceived Maternal Parenting Style And Perceived Emotion Regulation In Seventh-Day Adventists In Southern Brazil, Camila Cardoso Masotti

Master's Theses

Problem.\

One's ability to regulate his/her emotions utilizing coping mechanisms and dissuasive mental strategies is partly attained due to the correct functioning of innate biological systems and to life experiences that promote learning/training in this area (cf., e.g., Matsumoto & Hwang, 2012). The field of emotion regulation studies has extensively elaborated on a multivalent description of human emotional development, in which emotions are part of essential mental strategies for an individual's conscious and unconscious goals in life (cf., e.g., Lang & Bradley, 2010; Levenson, 1999). Therefore, as a partly learned ability, one's emotion regulation skills have been shown as positively …

Sundowners And Mountain Wave Activity: Selected Observations From The Sundowner Winds Experiment (Swex), Kiera L. Malarkey

Master's Theses

Wildfires in complex terrain have resulted in tragic loss and have highlighted the vulnerability of communities over the past several years. The added intensity created by downslope windstorms, and the lack of high temporal and spatial resolution of ground observations motivates the ongoing need to understand and increase predictability of Sundowners. Sundowners, downslope windstorms that are typically intensified around sunset, are a common and significant weather phenomenon observed along the Santa Barbara coastline and are known to increase challenges during wildfire events. The Sundowner Winds EXperiment (SWEX) was a six-week field campaign from 01 April to 15 May 2022 in …

Spatiotemporal Dynamics And Biogeochemical Responses In A Tidally Restricted Moro Cojo Slough, Ryan Chiu

Master's Theses

Four years of observational data for Moro Cojo Slough (MCS), a Mediterranean climate estuary in central California, linked anthropogenic nutrient loading and hydrological modifications to a shift in net ecosystem metabolism (NEM) that differs from the characteristic net heterotrophic behavior of most estuarine systems. A lack of precipitation and limited flushing during the dry seasons, as evidenced from hypersaline waters, contribute to high ecosystem respiration rates that drove NEM to nearly balanced or net autotrophic. During the wet seasons, increased runoff and nutrient loading due to precipitation elevated primary production rates within MCS, characterizing the system as net autotrophic. Box …

Where And Why Do Ecosystem-Based Adaption Projects Take Place In California?, Daniel K. Jacobson

Master's Theses

California is experiencing the harmful impacts of climate change and will continue to do so for generations. As a result, municipalities have been forced to turn to adaptation solutions to help local residents adjust to inevitable impacts such as sea level rise, extreme heat, and extreme weather. Ecosystem-based adaptation (EbA), the use of nature and ecosystem services to help human systems adapt to climate change impacts, is an increasingly popular, cost-effective, and multi-benefit adaptation strategy. While prior research has shown that other forms of adaptation, often referred to as ‘hard’ and ‘soft’ strategies, disproportionately benefit whiter and wealthier populations, there …

Impacts Of The Poultry Industry In Mississippi, Sara Watts

Master's Theses

This thesis examines the impacts of the poultry industry in seven counties in the Piney Woods region of South Mississippi: Wayne, Jones, Forrest, Lamar, Jefferson Davis, Marion, and Pike. Current research indicates that the poultry industry has a significant impact on the cultures and economies of rural towns throughout the United States. There is no current research that examines the effects of the poultry industry on residents of the Piney Woods. This thesis addresses that gap in the research and contributes to current understanding of how the industry molds and impacts the lives of those intimately associated with it.

How A Book Changed A Nation [2022], Teodora Buzea

Master's Theses

“We don’t believe in vampires.”

I didn’t bother to turn away from the TV to look at my parents. On screen, a crew of young men were interviewing an old woman. She spoke only Romanian, and a too-perfect female voice spoke for her in English. I could see the confident fear in her expression as she exclaimed that vampires were indeed real and that she was always scared of them. She wasn’t alone. All of Transylvania were aware of the existence of vampires. Truly, these young men— ghost hunters and cryptologists—were right to come here to this haunted nation. The …

The Rise Of Terrorism In Africa And What It Means For U.S. Policymakers, Bridget Mary Hughes

Master's Theses

This thesis utilizes three case studies to measure the rise of terrorism in Africa. This qualitative data leads the reader to one ultimate question: what does the rise in terrorism in Africa mean for the United States (U.S.) and U.S. policymakers, National Security academia, students in National Security, if anything at all? The answer is: if civilian and military compounds are being targeted by these violent extremists, as these three case studies demonstrate, it is my recommendation that U.S. policymakers cease sending troops to the African theater and, instead, allocate funding to the citizens and nonprofits of the countries whom …

Wildfire Spread Prediction Using Attention Mechanisms In U-Net, Kamen Haresh Shah, Kamen Haresh Shah

An investigation into using attention mechanisms for better feature extraction in wildfire spread prediction models. This research examines the U-net architecture to achieve image segmentation, a process that partitions images by classifying pixels into one of two classes. The deep learning models explored in this research integrate modern deep learning architectures, and techniques used to optimize them. The models are trained on 12 distinct observational variables derived from the Google Earth Engine catalog. Evaluation is conducted with accuracy, Dice coefficient score, ROC-AUC, and F1-score. This research concludes that when augmenting U-net with attention mechanisms, the attention component improves feature suppression …

Ectotherm Thermoregulation At Fine Scales: Novel Methods Reveal A Link Between The Spatial Distribution Of Temperature And Habitat Quality, Ian Axsom

Master's Theses

Investigating ecological questions at the scale of individual organisms is necessary to understand and predict the biological consequences of environmental conditions. For small organisms this can be challenging because we need tools with the appropriate accuracy and resolution to record and quantify their ecological interactions. Unfortunately, many of our existing tools are only appropriate for medium to large organisms or those that are wide ranging, inhibiting our ability to investigate the ecology of small organisms at fine scales.

In Chapter 1, I tested a novel workflow for recording animal movements at very fine spatial and temporal scales. The workflow combined …

Astragalus osterhoutii M.E. Jones (Fabaceae) is a federally listed, rare, endemic species restricted to seleniferous soils in Grand County, CO (Anderson, 1989). This research utilized both RADseq and RNAseq to generate neutral and adaptive genomic datasets. Neutral data analysis aimed to determine i) the genetic diversity of A. osterhoutii and each of its populations level, ii) how genetic structure is partitioned across the species range, and iii) the closest relative to A. osterhoutii. Analysis of adaptive, RNAseq data aimed to identify i) differentially expressed genes, ii) if patterns of expression are similar to neutral data, and iii) differences in Se …

From Mesoamerica To Aleppo And Transylvania: The Global Migration Of The Chile Pepper, Arianne M. Peterson, Arianne Peterson

Master's Theses

This thesis explores the migration of the chile pepper, or capsicum anuum, from Mesoamerica into the Old World after 1500, focusing on two case studies of the Aleppo pepper in Syria and paprika in what was once Hungarian Nagyvarad, and which is now Romanian Oradea. Using foodways as a historical lens, and considering the movement of food as historical, it can be seen that the chile pepper, despite its low profit value, illustrates a globalization that existed well before modern times, and it came to cement itself within many different cultures as a symbol of identity. Despite its far-away …

Constructing Planetary Citizens Through Ecopedagogy In U.S. Social Studies Standards, Madeline Anne Rainey

Master's Theses

The world is in the age of the Anthropocene, where humans are impacting the environment to disastrous effects. The capitalist economy, promoting neoliberal policies of mass consumption, has exacerbated the world's environmental deterioration and social inequity. The rights and responsibilities people hold have been rapidly changing with the fourth industrial revolution. Globalization and Information and Communications Technology (ICT) have further expanded notions of citizenship. While there have been numerous attempts to bring the environment into schools, it has not emphasized what this crisis deserves. Ecopedagogy, as a critical theory, explicitly examines the interplay between environmental and social problems and challenges …

Deep Learning For Detecting Trees In The Urban Environment From Lidar, Julian R. Rice

Master's Theses

Cataloguing and classifying trees in the urban environment is a crucial step in urban and environmental planning. However, manual collection and maintenance of this data is expensive and time-consuming. Algorithmic approaches that rely on remote sensing data have been developed for tree detection in forests, though they generally struggle in the more varied urban environment. This work proposes a novel method for the detection of trees in the urban environment that applies deep learning to remote sensing data. Specifically, we train a PointNet-based neural network to predict tree locations directly from LIDAR data augmented with multi-spectral imaging. We compare this …

Evolving Deforestation Narratives In Practice: A Study Of The Un-Redd+ Readiness Programme In Nigeria, Stuart Clive Blackwell

Master's Theses

The UN-REDD+ Readiness Programme was conducted between 2009 and 2015. The REDD+ Programme in Nigeria began once the readiness program was completed. This study conducts a document analysis of the program utilizing a political ecology lens to determine the extent to which the program adheres to or strays away from critical narratives surrounding both drivers of deforestation and inclusion and autonomy of federal, state, and local communities. By examining the entirety of the available documentation of the REDD+ Readiness program in Nigeria using a political ecological lens, this study demonstrates both an evolution of the program itself, and an evolution …

Tropical Cyclone Storm Surge Detection In Slash Pine Radial Growth Along The Northern Gulf Of Mexico Coastline, Alyssa C. Crowell

Master's Theses

My thesis examines the ecological impact of tropical cyclone (TCs) storm surge on coastal slash pine (Pinus elliottii var. elliottii Engelm) communities along the Gulf of Mexico in the southern United States (U.S.). Previous research has shown slash pine radial growth trends can be examined to identify long and short-term growth changes associated with TC passage, providing insight into overall stand health and resiliency through time. However, this previous research encompasses just one site in Mississippi. My thesis expands the spatial footprint of TC-surge impact on slash pine radial growth with the addition of three new sites.

I examined …

Measuring Accessibility For Pedestrians, Bicyclists, And Transit Riders To Grocery Stores In The Excelsior/Outer Mission Neighborhoods Of San Francisco, Alexandra Lee-Gardner

Master's Theses

Grocery stores are an important amenity in neighborhoods and access to grocery stores is important for health and well-being. While grocery store accessibility is a popular topic of research, studies measuring access for pedestrians, bicyclists, and transit riders are extremely rare. When a new store opened in the Excelsior/Outer Mission districts of San Francisco on a street lacking basic infrastructure for pedestrians, bicyclists, and transit riders, the importance of this study became apparent. The Excelsior/Outer Mission neighborhood has a shocking number of collisions (over 1,100 between 2015 and 2019), elevated levels of walking, biking, and transit ridership, and minimal safe …

Legislative Language For Success, Sanjana Gundala

Master's Theses

Legislative committee meetings are an integral part of the lawmaking process for local and state bills. The testimony presented during these meetings is a large factor in the outcome of the proposed bill. This research uses Natural Language Processing and Machine Learning techniques to analyze testimonies from California Legislative committee meetings from 2015-2016 in order to identify what aspects of a testimony makes it successful. A testimony is considered successful if the alignment of the testimony matches the bill outcome (alignment is "For" and the bill passes or alignment is "Against" and the bill fails). The process of finding what …

Simulating Electric Vehicle Short-Notice Wildfire Evacuation In California Rural Communities, Gudrun Derickson

Master's Theses

The transportation sector in California has begun a shift toward adopting Electric Vehicles (EVs) as a primary source of individual and corporate mobility. The US Government and the State of California are initiating public-sector financed charging station infrastructure to help in this change-over to EVs. Automobile companies and private enterprises are also heavily investing in Battery Electric Vehicle (BEV) infrastructure going forward. The state of California is subject to natural disasters such as Fire, Earthquakes, and periodic flooding. Increasing numbers of BEVs may add new challenges to mass evacuations that are often associated with natural disasters. This work focuses on …

Impact Of Climate Variability On Child Nutrition In Ethiopia, Juan S. Gomez

Master's Theses

Changes in precipitation and temperature due to climate change have caused a shortage in food productivity leading to an increase in malnutrition outcomes, especially among children in developing countries that are more susceptible to undernutrition outcomes. This study contributes to existing literature studying the impact of climate variability measured by temperature, precipitation, and vegetation index on wasting. Wasting is measured by the weight for height score during the main growing season (Meher) using Demographic and Health Surveys data for five different periods in Ethiopia. Results suggest that lower NDVI outcomes are associated with an increase in the risk of acute …

Borders, Bodies And Abuse: Exposing The Collusion Of Australia And The United States In Transnational Refugee Deterrence, Kaytlin Hancock

Master's Theses

This research explores a comparison of the use and abuse of deterrence policies, namely the externalisation of borders, and spatial control aimed to disallow entry for refugees and asylum seekers arriving by boat to both the United States and Australia. Paying particular attention to the immigration occurrences in the US from the early 1980s and present day responses in Australia, this research explores the rise in offshore detention centres and the ways in which these countries shirk their international obligations in a bid to strengthen sovereignty, by creating zones of exemption that expel refugees and asylum seekers to liminal spaces. …

The Belt And Road Initiative In Kenya, As Represented By The Standard Gauge Railway (Sgr), Its Effects And The Response Of Kenyans To It., Kiplangat Arap Yegon

Master's Theses

China has sought to strengthen ties with many countries in the Global South, and many African countries have signed Memorandum of Agreements(MoU) with China leading to trade treaties, foreign direct investments, loans and grants flowing into the African continent from China. This aggressive push by China into Africa has come under intense scrutiny with different actors, scholars and powers having mixed takes on the move. In my thesis, I look at the ways in which China’s Belt and Road Initiative has been undertaken in Africa. I use Kenya as a main case study in looking at the ways in which …

Influence Of Altitude And Scan Angle On Uas-Lidar Ground Height Measurement Accuracy In Juncus Roemerianus Scheele (Black Needle Rush)-Dominated Marshes, Michael Amelunke

Master's Theses

Coastal marshes are influenced by complex interactions among environmental and human factors. Marsh plant communities exist across subtle elevation gradients which are highly influenced by the local tidal regime. To better understand these dynamic conditions, improved methodologies for acquiring accurate elevation values are a necessity in marsh research and management. However, overestimation of marsh elevation values obtained from remote sensing is common due to vegetation characteristics. The goal of this study was to address this problem by determining the optimum altitude and scan angle for Light Detection and Ranging (LiDAR) collection using an Unmanned Aerial System (UAS) within Juncus roemerianus …

Recovery From Minor Tropical Cyclones: The Response Of Faith-Based Organizations And Government Agencies To Minor Tropical Cyclones In Biloxi, Mississippi, Camilla Witherspoon

Master's Theses

The impacts of major hurricanes are extensively researched in Disaster Resilience literature and the field of Human Geography; in contrast, the aftermath of minor tropical cyclones is understudied. Along the Gulf Coast in 2020 and 2021, more minor tropical cyclones made landfall then major hurricanes (NOAA, 2021). Despite the frequency of minor tropical cyclones, few studies have considered the resources and actors involved in recovery from minor tropical cyclones.

This thesis uses qualitative methods, including semi-structured interviews and document collection, to examine how Faith-based Organization (FBO) and government agency leaders in Biloxi, Mississippi provide resources to residents, interact with each …

The Plague And The Parthenon: Crusade, Climate Change And Disease In The Early Modern Mediterranean, John Mark Nicovich

Master's Theses

The present study examines the role epidemic diseases, specifically malaria and bubonic plague, played on the course of the Morean War (1684-1699). The Morean War was a major offensive by Christian powers, led by the Venetian Republic, against Ottoman controlled Greece. Christian victories during the war were widely celebrated across western Europe, but even in victory Christian forces took severe casualties from multiple disease outbreaks. First, this study seeks to explain the terrestrial and maritime networks the war was fought over, and how those networks either led the opposing forces into regions of endemic disease (malaria), or how they allowed …

Subjective Observation Of Loss Of Subcutaneous Fat And Muscle Tissue – Is That The Answer To Pediatric Hospital Malnutrition Screening?, Grace C. Barcus

Master's Theses

Background: Hospital malnutrition is a prevalent issue with critically ill pediatric patients being at increased risk for nutritional loss. Nutritional risk screening has been associated with increased documentation of nutrition diagnosis and positive clinical outcomes, however, is not mandatory in developing countries. A nutrition screening tool that uses subjective examination of loss of subcutaneous fat and muscle tissue may be an efficient way to identify nutritional risk in hospitalized critical care pediatric patients.

Objective: To determine whether loss of subcutaneous fat and muscle tissue in specific body locations was associated with moderate or severe malnutrition determined by SGA in pediatric …

Using Deep Learning And Uav Imagery To Detect Elkhorn Coral In St. Croix’S East End Marine Park, Samuel Wyatt

Master's Theses

Elkhorn coral, or Acropora palmata, is an important reef building species that promotes species abundance and other ecological services to the communities in the US Virgin Islands. We captured high resolution imagery of a reef in St. Croix’s East End Marine Park using a Wingtra One UAV. We then used deep learning techniques to detect individual coral colonies. We compared two deep learning models, FasterRCNN and MaskRCNN, and found that the models achieved accuracy shores up to 0.78. These scores improved when examining only larger corals in shallow waters. The model was able to both detect Elkhorn coral and …

Translatina Immigrant Mental Health Wellness: Suggestive Intervention Strategies The City Of San Francisco Should Consider Adopting, Valeria Vera

Master's Theses

Translatina immigrants in the United States often suffer from intersectional traumas due to their race, gender, sexual orientation, religion, and immigration status — putting them in a vulnerable position socially, psychologically, economically, and medically. Due to their positionality in the intersections of migration, criminalization, cissexism, and mental health, they are often more marginalized and have greater needs than communities with privileged sociocultural identities. As a particularly vulnerable group, they need guaranteed access to gender-affirming healthcare that is inclusive of mental health services. Despite Translatinas’ need for mental health services, there exist many barriers making services inaccessible and insufficient in San …

An Investigation Of The Relationship Of Wave Intensity And Byssal Thread Strength Of The Mussel Mytilus Californianus, Felicia M. Miller

Master's Theses

The intertidal zone is a stressful environment with one of the main stressors being the fluctuation of wave energy over time and space. A structural adaptation employed by mussels living within the intertidal zone is byssal threads that aid in attachment while dealing with various levels of wave exposure. The California mussel, Mytilus californianus, lives in extremely wave exposure conditions, which makes it a great study species to assess the relationship between wave intensity and byssal thread strength. In this study, Mytilus californianus were collected from two locations in the Monterey Bay, each with a predicted wave exposed site and …

The Influence Of Teleconnection Patterns On Renewable Energy Resources, John Kyle Bergerson

Master's Theses

Energy providers are shifting their supply from carbon based forms of energy to renewable sources in response to policy changes aimed at reducing pollution and anthropogenic influence on the environment. Wind and solar energies are notable sources that have been adopted around the globe and are increasing in installation and efficiency, but relying on weather-dependent sources of energy has limitations. Variability in energy supply and demand becomes further dependent on the state of the climate, and thus predictability of that state is critical. Climate modes are correlated with climate variables and are used to make mid-term (>10 days), seasonal, …
