Automated Identification And Mapping Of Interesting Mineral Spectra In Crism Images, Arun M. Saranathan

Doctoral Dissertations

The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) has proven to be an invaluable tool for the mineralogical analysis of the Martian surface. It has been crucial in identifying and mapping the spatial extents of various minerals. Primarily, the identification and mapping of these mineral spectral-shapes have been performed manually. Given the size of the CRISM image dataset, manual analysis of the full dataset would be arduous/infeasible. This dissertation attempts to address this issue by describing an (machine learning based) automated processing pipeline for CRISM data that can be used to identify and map the unique mineral signatures present in …

Greenwashing “Brown Gold”: A Critical Analysis Of Anaerobic Digesters And California’S Neoliberal Environmental Programs In Wisconsin’S Dairyland, Sarah Emily D'Onofrio

Doctoral Dissertations

Large dairy farms, also known as concentrated animal feeding operations (CAFOs), have turned to anaerobic digesters as the industry is increasingly pressured to find ways to lower their greenhouse gas emissions. Digesters are machines that turn animal waste from CAFOs into electricity and fuel which are then sold as “credits” in California’s market based climate change mitigation programs such as cap and trade and the low carbon fuel standard (LCFS) program. However, this dissertation not only challenges the assertion that digesters are “green,” but also that these programs are doing what they claim to do in a deregulated and re-regulated …

This dissertation contains studies investigating several facets of the urban forest, including environmental effects of deforestation and urbanization, tree equity, and urban forest facility management and accessibility. Community education and outreach at arboreta about the importance of the tree canopy can help promote environmental stewardship. A digital questionnaire was electronically distributed to representatives of arboreta certified through the Tennessee Division of …

Climatological Analysis Of Tropical Cyclone Occurrence Dates And Landfall Characteristics In The North Atlantic And Eastern North Pacific, Nicholas Sava Grondin

Doctoral Dissertations

Tropical cyclones (TCs) are significant hazards to coastal and inland regions across the globe, especially in North America. North America is affected by TCs from two basins, the North Atlantic (NATL) and eastern North Pacific (ENP), with the former being the predominate focus of past research. In this dissertation, I present three studies that directly compare TCs in the NATL and ENP by using the same methods for each basin in studying occurrence dates and intraseasonal variability, effects of environmental parameters on occurrence dates and seasonal forecasting, and the behavior of TCs during the final 36 hours before landfall in …

Genealogy Tells: Informing Health And Aging Policies Using East Tennessean Older Women's Family Histories, Perceptions, And Experiences Of Health Inequity, Heather Davis

Doctoral Dissertations

Older women face unique health inequities challenges. This study aims to provide an understanding of older women’s perceptions and situated experiences regarding the gendered health inequities they face and the social determinants (SDH) thereof. It examines how these health inequities are situated in older women’s genealogical (familial) and geographical health and mortality outcomes histories and how their perceptions and experiences of health inequities and their familial mortality outcomes histories are characterized by the geopolitical and social norms in which they live. The purpose of this project is to present policy and decision-makers with insights about and recommendations from older women …

Access Beyond Geographic Accessibility: Understanding Opportunities To Human Needs In A Physical-Virtual World, Jimmy Feng

Doctoral Dissertations

Access to basic human needs, such as food and healthcare, is conceptually understood to be comprised of multiple spatial and aspatial dimensions. However, research in this area has traditionally been explored with spatial accessibility measures that almost exclusively focus on just two dimensions. Namely, the availability of resources, services, and facilities, and the accessibility or ease to which locations of these opportunities can be reached with existing land-use and transport systems under temporal constraints and considering individual characteristics of people. These calculated measures are insufficient in holistically capturing available opportunities as they ignore other components, such as the emergence of …

The Global Impact Of The Antarctic Ice Sheet In A Warming World: Using Numerical Modeling And Critical Physical Geography To Assess Climate Change, Sea Level Rise, And Climate Justice

Doctoral Dissertations

Anthropogenic climate change is causing disruptions in the Earth system with negative ramifications for life on our planet. Increasing atmospheric greenhouse gas concentrations lead to accumulated heat content and the cryosphere is one of the earliest places to show changes in response to rising temperatures. The melting of the Antarctic Ice Sheet will have myriad effects on global climate due to interconnections and feedbacks between the ice sheet, ocean, and atmosphere. In this dissertation I use numerical modeling and critical geography to assess future climate conditions that occur in response to changes in Antarctic Ice Sheet melt as well as …

Making The Old City: Life Projects And State Heritage In Rhodes And Acre, Evan Taylor

Doctoral Dissertations

The “old city,” a widely recognizable category of urban space, has long been a locus of development projects, state monitoring, and mass tourism, while also being home to resident communities. This dissertation explores the intersections of community life and state-driven heritage projects in the Old Town of Rhodes, in the Greek Dodecanese, and the Old City of Acre (‘Akka), a Palestinian community in northern Israel/Palestine. Both old cities are UNESCO World Heritage sites and subjects of intense state-supported tourism development. However, their resident populations and their built environments, which coalesced mainly under Crusader and Ottoman rule, challenge the authorized heritage …

Residents' Perspectives Of Young, Street-Facing Trees: Three Cases From Legacy Cities With Active Tree Planting Initiatives, Alicia Coleman

Doctoral Dissertations

Organized tree planting initiatives are underway in cities across the world in order to expand tree canopy cover, combat environmental threats, and create more livable places for urban residents. Trees along and near city streets provide a number of services for residents; however, evidence from environmental design and landscape preference research suggests that the perceptual effect of large-statured, mature trees may differ from small-statured, young trees. This dissertation explored these differences in three studies based in communities with active tree planting initiatives. Chapter 2 compares tree preferences from a hypothetical tree planting initiative to preferences for trees in other settings …

Human Dimensions Of Natural Resources: A Case Of Farmers In Northern Rwanda, Jean Francois Regis Nisengwe

Doctoral Dissertations

As food demand increases globally, the world faces the challenge of feeding everyone without harming the environment. Meeting this challenge requires increased food production. Paradoxically, increased food production can harm the environment and natural resources. Change in consumption patterns offers an opportunity to reconcile the increase in food production and environmental protection. However, consumption patterns can only change if they are perceived first, then acted upon. Research shows that people who perceive their consumption of natural resources are more likely to conserve them as they can see how much they are consuming. This study investigated perceptions of natural resources and …

Perceptions Of Historical Climate Change And Park Policy: The Impact On The Fremont Cottonwood In Zion National Park, Kathleen Kavarra Corr

Doctoral Dissertations

Despite its “natural” appearance and the Organic Act 1916 mandate for preservation of the natural environment in National Parks, the Virgin River as it flows through Zion National Park’s Zion Canyon was transformed through massive flood control re-engineering projects in the 1930s. The armoring of the river has had significant impacts on riparian vegetation, particularly on the stands of native Fremont Cottonwood trees that once filled the narrow valley. What was the motivation for this massive flood control project carried out in an arid region with less than 15 inches of rain per year? This dissertation explores the motivations which …

Reclaiming The Future Through Small-Scale Agriculture: Autonomy And Sustainability In The Caribbean, Dana M. Conzo

Doctoral Dissertations

My dissertation, “Reclaiming the future through Small-Scale Agriculture: Autonomy and Sustainability in the Caribbean,” is a political-economic analysis of land politics, foodscapes and foodsheds, and small-scale agricultural activities in plantation economies on the Caribbean island of St Kitts. Using ethnographic and geographic methods, such as participant observation, interviews, social network analysis, and foodshed mapping, I investigate the cultural and economic niche of local farmers, documented and analyzed the island’s foodshed, and provide a historical and economic background of St Kitts to link historical processes to contemporary spatial organization and agricultural practices. I consider the complexities of food inequalities and food …

Care Work In Chile’S Segregated Cities, Manuel Garcia

Doctoral Dissertations

This project combines diverse theoretical and methodological tools to examine the relationship between space and care work in Chile. The chapters are stand-alone articles that come together to tell a single story. The social production of urban space has marginalized thousands of female caregivers from the labor market as Chile’s care system unravels. I argue that community caregiving could simultaneously improve the conditions of caregivers and dependents. Chapter 1 examines the role of residential segregation in reproducing Chile’s meager female labor market participation rates. I use spatial and econometric analysis to show that the social forces that segregate Santiago create …

Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan

Doctoral Dissertations

Carnivores are distributed widely and threatened by habitat loss, poaching, climate change, and disease. They are considered integral to ecosystem function through their direct and indirect interactions with species at different trophic levels. Given the importance of carnivores, it is of high conservation priority to understand the processes driving carnivore assemblages in different systems. It is thus essential to determine the abiotic and biotic drivers of carnivore community composition at different spatial scales and address the following questions: (i) What factors influence carnivore community composition and diversity? (ii) How do the factors influencing carnivore communities vary across spatial and temporal …

China's Urbanization Model And Its Practice In Western China: A Case Study Of Urbanization In Xining, Qinghai, Xin Li

Doctoral Dissertations

China’s unprecedented urban expansion has drawn extensive scholarly and public attention. The mechanisms and fundamental changes that the urbanization process has brought to Chinese cities have been heatedly discussed in the academic realm. However, research attention has been largely paid to the eastern coastal region. Western Chinese cities in contrast, although they have been catching up with the economic and urban development with two-digit growth in the past two decades, have received relatively little attention. This dissertation analyzes the driving forces, characteristics, and impacts of this recent urban expansion in western Chinese cities. In particular, it focuses on Xining, a …

Negotiating Space: Spatial Violation On The Early Modern Stage, 1587-1638, Gregory W. Sargent

Doctoral Dissertations

Recent criticism proves the malleability of theatrical space as a lens through which the discussion of Renaissance drama proliferates. Negotiating Space works towards the articulation of the importance of space in the representational mimesis of performance by examining moments of violence, violation, misuse, and misappropriation. I draw a connection between the lived, material sites of the plays’ action and the ideological import of representing those spaces dramatically using a focus on violation. Though much good scholarship exists detailing London-centric approaches to dramatic space, this study discursively reifies identifiable staged spaces to connect with the lives of theatrical patrons no matter …

Landslide Mapping And Susceptibility Assessment Of Chittagong Hilly Areas, Bangladesh, Yasin Wahid Rabby

Doctoral Dissertations

Landslides are natural phenomena in mountainous areas that cause damage to properties and death to people around the world. In Bangladesh, landslides have caused enormous economic loss and casualty in Chittagong Hilly Areas (CHA). In this dissertation, a landslide inventory of CHA was prepared using Google Earth and field mapping. Google Earth-based mapping helped in recording landslides in inaccessible areas like forests. In contrast, field mapping helped in mapping landslides in accessible areas like areas near road networks. For absence data sampling of landslide susceptibility mapping, this research proposed the Mahalanobis distance (MD) based absence data sampling and compared it …

Hazardous Weather And Human Response In The Southeastern United States, Daniel Burow

Doctoral Dissertations

Effectively mitigating the human costs of future hazardous weather events requires examining meteorological threats, their long-term patterns, and human response to these events. The southeastern United States is a region that has both a high climatological risk and a high societal vulnerability to many different meteorological hazards. In this dissertation, I study hazardous weather and human response in the Southeast through three different lenses: identifying uniquely simultaneous hazards posed by tropical cyclones, assessing precipitation and synoptic weather patterns on hazardous weather days, and examining patterns in intended response to tornado watches. I find that simultaneous and collocated tornado and flash …

Liberation And Gravy: An Engaged Ethnography Of Queer And Trans Power In Georgia, Elias Capello

Doctoral Dissertations

This dissertation aims to better understand how self-identified trans activists in Atlanta, Georgia find and build community, by using queer and Black feminist community based methodologies such as participant observation, ethnographic interviews, participatory mapping, and auto-ethnography. In particular, I ask 1) How do trans people find and build community, safety, and understanding? 2) How do transgender activists create and enact place making that does not rely on policing and privatization? To create and maintain safety for wealthy communities in Atlanta, Georgia, systems of policing and privatization are increasing. Although developers, city council members, and legislators promote Atlanta, Georgia as a …

Gis And Remote Sensing Groundwater Potentiality Investigation Of Gulu District, Uganda Using Synthetic Aperture Radar And Magnetic Geophysics, Rachel Ann Jones

Doctoral Dissertations

“Developing countries have few resources for ground-based hydrological investigations to determine optimal placement of boreholes for community water access. Remote sensing data are available at a variety of resolutions and sense different parameters, and are useful inputs for hydrologic models, but these data are rarely obtainable in developing countries with the parameters or resolutions necessary for hydrologic applications. This research seeks to use and improve existing remote sensing and GIS techniques to identify areas of optimal water supply in locations with limited geologic or hydrologic information, such as Gulu District, Uganda. Fusing different remotely sensed data sets can produce higher …

Predictive Geohazard Mapping Using Lidar And Satellite Imagery In Missouri And Oklahoma, Usa, Olufeyisayo B. Ilesanmi

Doctoral Dissertations

”Light Detection and Ranging (LiDAR) and satellite imagery have become the most utilized remote sensing technologies for compiling inventories of surficial geologic conditions. Point cloud data obtained from multi-spectral remote sensing methods provide a detailed characterization of the surface features, in particular, the detailed surface manifestations of underlying geologic structures. When combined, point clouds eliminate bias from visual inconsistencies and/or statistical values. This research explores the competence of point clouds derived from LiDAR and Unmanned Aerial Systems (UAS) as a predictive tool in evaluating various geohazards. It combines these data sets with other remote sensing techniques to evaluate the sensitivity …

Modeling Fire Observations, Ignition Sources, And Novel Fuels To Understand Human Impacts On Fire Regimes Across The U.S., Emily Fusco

Doctoral Dissertations

Fire is a natural, and necessary, component of many ecosystems. However, people are changing the spatial and temporal distribution of wildfires in the U.S. at great economic and ecological costs. My dissertation addresses the impacts of humans on U.S. fires both through the introduction of ignition sources and flammable grasses. Further, I evaluate fire datasets that are widely used to investigate these phenomena over large spatial and temporal scales. Finally, I create an aboveground carbon map that can be used to estimate the potential carbon loss consequences in western U.S. ecosystems most at risk to fire. My work shows that …

Rethinking The Creative Economy: The Diverse Economies Of Artists And Artisans In Rural Massachusetts, Abby Irene Templer Rodrigues

Doctoral Dissertations

This dissertation explores the contours of artistic economic activity through participatory action research conducted with artists and artisans in the Greater Franklin County, Massachusetts. The creative economy has drawn significant attention over the past ten years as a principle economic sector that can stimulate the redevelopment of post-industrial cities. However, dominant creativity–based development strategies tend to cater to the tastes of an economically privileged, and implicitly white, “creative class,’ leading to gentrification and social exclusion based on race, ethnicity, class, and gender. These exclusions also apply to artists and artisans, occupational groups whose economic activity and needs have been paradoxically …

The Korean Comfort Women Commemorative Campaign: Role Of Intersectionality, Symbolic Space, And Transnational Circulation In Politics Of Memory And Human Rights, Jihwan Yoon

Doctoral Dissertations

Since the end of WWII, Korea has experienced a miraculous economic development despite its devastated economic and political conditions originating from Japanese colonialism and the Korean War. However, while Korean society has concentrated on its socioeconomic advancement, few victims having traumatic memories of Japanese colonialism have been cared for by systematic and social treatment until recently. Especially, comfort women, who were sexually abused and exploited during WWII by the Japanese army, had not been able to testify their narratives in military brothels due to structural oppressions and distorted views against women in Korean society. In this respect, Wednesday Demonstration encouraged …

Effects Of Switchgrass Related Land-Use Changes On Aquatic Macroinvertebrates, Latha Malar Baskaran

Doctoral Dissertations

This research examines if switchgrass-based land-management practices have the potential to influence aquatic macroinvertebrates through changes in stream flow and water quality. The number of taxa in Ephemeroptera, Plecoptera, and Trichoptera orders (EPT taxa richness/EPT-TR) is analyzed as an aquatic macroinvertebrate bioindicator in the context of regional environmental effects, and changes in stream flow and water quality. This dissertation is structured as three manuscripts that link together to address the overall research question.

The first manuscript focuses on identifying regional environmental variables that influence EPT-TR across ecoregions in Tennessee. The influences of temperature, precipitation, geology, soil, stream flow and velocity …

Reflecting Human Knowledge Of Place And Route-Choice Behavior Using Big Data, Jiaoli Chen

Doctoral Dissertations

Exploring human knowledge of geographical space and related behavior not only helps in understanding human-environment interactions and dynamic geographic processes, but also advances Geographic Information Systems (GIS) toward a human-centric paradigm to make daily life more efficient. Today’s relatively easy acquisition of various big data provides an unprecedented opportunity for geographers to answer research questions that previously could not be adequately addressed. However, new challenges also arise regarding data quality and bias as well as change in methodology for dealing with big data that are different from traditional data types.

Representing people’s perception of place and studying driver’s route-choice behavior …

Capitals Of Punk: Paris, Dc, And The Circulation Of Urban Counternarratives, Tyler William Sonnichsen

Doctoral Dissertations

In the history of underground music in the punk era, few cities’ scenes have garnered as much respect and influence as Washington, DC. Bad Brains, Minor Threat, Scream, Rites of Spring, Fugazi, and a deep catalog of other regional groups have accrued legendary status among fans of hardcore and have become subjects of popular books and documentaries. However, few accounts have investigated DC’s underground influence on other urban landscapes outside of the United States. This dissertation focuses on that relationship between DC and another iconic Western capital with a largely unheralded hardcore punk history, Paris.

Using qualitative, ethnographic methods, this …

Dynamics Of Collaborative Navigation And Applying Data Driven Methods To Improve Pedestrian Navigation Instructions At Decision Points For People Of Varying Spatial Aptitudes, Gengen He

Doctoral Dissertations

Cognitive Geography seeks to understand individual decision-making variations based on fundamental cognitive differences between people of varying spatial aptitudes. Understanding fundamental behavioral discrepancies among individuals is an important step to improve navigation algorithms and the overall travel experience. Contemporary navigation aids, although helpful in providing turn-by-turn directions, lack important capabilities to distinguish decision points for their features and importance. Existing systems lack the ability to generate landmark or decision point based instructions using real-time or crowd sourced data. Systems cannot customize personalized instructions for individuals based on inherent spatial ability, travel history, or situations.

This dissertation presents a novel experimental …

Remediating A Toxic Town: Power, Place, And Justice In Anniston, Alabama, Melanie Ann Barron

Doctoral Dissertations

This dissertation examines a struggle for Environmental Justice over the long term to understand the impacts of current state-led strategies for achieving Environmental Justice. Recent geographic scholarship in Environmental Justice literatures suggests that state-centric strategies come with problems scholars have yet to fully comprehend. This dissertation, based on fieldwork and archival research in Anniston, Alabama, supports this claim with three main findings: 1) Corporations produce scaled identities to advantageously empower themselves and weather shifts in their profitability, while ordinary people are limited in their capacity to respond in kind to such unequal power arrangements. 2) Current legal solutions for Environmental …

Reconstructing Late Holocene Fire, Agriculture, And Climate From Sediment Records In Costa Rica And The Dominican Republic, Erik Nicholas Johanson

Doctoral Dissertations

We use multiple proxies from sediment cores to identify periods of climate stress during the late Holocene across the circum-Caribbean region and to determine how fire activity and signals of Pre-Columbian agriculture coincide with these arid periods. We examine evidence of aridity from stable carbon isotope ratios and shifts in elemental composition, along with pollen and microscopic charcoal, at Bao Bog in the highlands of Hispaniola. We infer two major periods of aridity (3600–2300 and 1040–850 cal yr BP), with the later period associated with the late phase of the Terminal Classic Drought. A third, less marked interval of aridity …
