Broccoli Over Brownies: Factors Affecting Healthy Food Choices For Low Income Residents Of Sioux Falls, South Dakota, Aileen Patricia Profir Jan 2021

Broccoli Over Brownies: Factors Affecting Healthy Food Choices For Low Income Residents Of Sioux Falls, South Dakota, Aileen Patricia Profir

Electronic Theses and Dissertations

The world is on the cusp of a nutritional crisis: malnutrition, in all its forms, now directly affects one in three persons on the planet. Chronic malnutrition is closely associated with a wide range of public health issues such as stunted growth, increased incidence of disease, school or work absences, and obesity. Access to proper nourishment for food insecure individuals is often evaluated as a measure of distance to market, yet a causal relationship between proximity to food resources and improved health outcomes is unclear. Multiple dimensions of food access influence fruit and vegetable consumption for those who are food …


Classification And Evaluation Of Extended Pics (Epics) On A Global Scale For Calibration And Stability Monitoring Of Optical Satellite Sensors, Juliana Maria Fajardo Rueda Jan 2021

Classification And Evaluation Of Extended Pics (Epics) On A Global Scale For Calibration And Stability Monitoring Of Optical Satellite Sensors, Juliana Maria Fajardo Rueda

Electronic Theses and Dissertations

As targets for the calibration and monitoring of optical satellite sensors, historically stable areas across North Africa have been used, known as Pseudo Invariant Calibration Sites PICS. However, two major drawbacks exist for these sites; first is the dependency on a single location to be always invariant, and second is the limited amount of observation achieved using these sites. As a result, longer time periods are needed to construct a dense data set to assess the radiometric performance of on-orbit optical sensors, and be convinced that the change detected is sensor-specific rather than site-specific. This work presents a global land …


Using New And Long-Term Multi-Scale Remotely Sensed Data To Detect Recurrent Fires And Quantify Their Relationship To Land Cover/Use In Indonesian Peatlands, Yenni Vetrita Jan 2021

Using New And Long-Term Multi-Scale Remotely Sensed Data To Detect Recurrent Fires And Quantify Their Relationship To Land Cover/Use In Indonesian Peatlands, Yenni Vetrita

Electronic Theses and Dissertations

Indonesia has committed to reducing its greenhouse gases emissions by 29% (potentially up to 41% with international assistance) by 2030. Achieving those targets requires many efforts but, in particular, controlling the fire problem in Indonesia’s peatlands is paramount, since it is unlikely to diminish on its own in the coming decades. This study was conducted in Sumatra and Kalimantan peatlands in Indonesia. Four MODIS-derived products (MCD45A1 collection 5.1, MCD64A1 (collection 5.1 and 6), FireCCI51) were initially assessed to explore long-term fire frequency and land use/cover change relationships. The results indicated the product(s) could only detect half of the fires accurately. …


Use And Improvement Of Remote Sensing And Geospatial Technologies In Support Of Crop Area And Yield Estimations In The West African Sahel, Kaboro Samasse Jan 2021

Use And Improvement Of Remote Sensing And Geospatial Technologies In Support Of Crop Area And Yield Estimations In The West African Sahel, Kaboro Samasse

Electronic Theses and Dissertations

In arid and semi-arid West Africa, agricultural production and regional food security depend largely on small-scale subsistence farming and rainfed crops, both of which are vulnerable to climate variability and drought. Efforts made to improve crop monitoring and our ability to estimate crop production (areas planted and yield estimations by crop type) in the major agricultural zones of the region are critical paths for minimizing climate risks and to support food security planning. The main objective of this dissertation research was to contribute to these efforts using remote sensing technologies. In this regard, the first analysis documented the low reliability …


Quantifying The Impacts Of Land Use, Management And Climate Change On Water Resources In Missouri River Basin, Arun Bawa Jan 2021

Quantifying The Impacts Of Land Use, Management And Climate Change On Water Resources In Missouri River Basin, Arun Bawa

Electronic Theses and Dissertations

A location-specific evaluation of hydrological landscape responses concerning past and projected climate and land use land cover (LULC) changes can provide a powerful intellectual basis for developing efficient and profitable agroecosystems, and overcoming uncertain and detrimental consequences of LULC and climate shifts. This dissertation assessed the impacts of land use, management, and climate change on water resources in the Missouri River Basin (MRB) through four specific studies that included: (i) to study the responses of leached nutrient concentrations and soil health to winter rye cover crop (CC) under no-till corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotation, (ii) to …


Will Zoning Fix Itself?, Michael Lewyn Jan 2021

Will Zoning Fix Itself?, Michael Lewyn

Scholarly Works

Typically, zoning artificially limits housing supply, thus increasing housing costs. One possible defense of this system is that zoning can fix itself- that is, that when rents and housing costs become unusually high, politicians will deregulate and thus reduce housing costs. This article suggests that such a happy result is unlikely; instead, where housing costs spiral out of control, voters and politicians are likely to make regulation even more strict out of a fear of gentrification.

Political Science & Geography Faculty Publications

This study evaluates the spatial-temporal patterns in Virginia tornadoes using the National Weather Service Storm Prediction Center’s Severe Weather GIS (SVRGIS) database. In addition to descriptive statistics, the analysis employs Kernel Density Estimation for spatial pattern analysis and space-time cubes to visualize the spatiotemporal frequency of tornadoes and potential trends. Most of the 726 tornadoes between 1960–2019 occurred in Eastern Virginia, along the Piedmont and Coastal Plain. Consistent with other literature, both the number of tornadoes and the tornado days have increased in Virginia. While 80% of the tornadoes occurred during the warm season, tornadoes did occur during each month …

Assessing And Forecasting Chlorophyll Abundances In Minnesota Lake Using Remote Sensing And Statistical Approaches, Ben Von Korff Jan 2021

Assessing And Forecasting Chlorophyll Abundances In Minnesota Lake Using Remote Sensing And Statistical Approaches, Ben Von Korff

All Graduate Theses, Dissertations, and Other Capstone Projects

Harmful algae blooms (HABs) can negatively impact water quality, lake aesthetics, and can harm human and animal health. However, monitoring for HABs is rare in Minnesota. Detecting blooms which can vary spatially and may only be present briefly is challenging, so expanding monitoring in Minnesota would require the use of new and cost efficient technologies. Unmanned aerial vehicles (UAVs) were used for bloom mapping using RGB and near-infrared imagery. Real time monitoring was conducted in Bass Lake, in Faribault County, MN using trail cameras. Time series forecasting was conducted with high frequency chlorophyll-a data from a water quality sonde. Normalized …


What Happened In Harris Neck?: Racism, Resistance, And Futures, Anna Sharpe Jan 2021

What Happened In Harris Neck?: Racism, Resistance, And Futures, Anna Sharpe

Theses and Dissertations--Geography

This project traces the history and legacy of the seizure of Harris Neck, approximately 2,600 acres on the Georgia coast, once largely composed of rice and cotton plantations. After the Civil War, freedmen and women transformed the area into a thriving Black community. The community of approximately a hundred families, a school, a church, a post office, and many small farms and businesses flourished from the late 1800’s until 1942, when the federal government seized Harris Neck for use as an Army airfield.

The procedures used by the federal government to seize and, later, reallocate Harris Neck will be examined, …


Political Economy Of The Production Of Heritage Space In A Centro Histórico: Attracting Real Estate Capital, Expelling People. The Case Of Cartagena (Colombia), Camilo Rey-Sabogal Jan 2021

Political Economy Of The Production Of Heritage Space In A Centro Histórico: Attracting Real Estate Capital, Expelling People. The Case Of Cartagena (Colombia), Camilo Rey-Sabogal

Theses and Dissertations--Geography

Cartagena is a South American city whose historical built environment has been recognized as a World Heritage Site due to the preservation of elements of the Spanish military architecture of the 16th, 17th and 18th centuries. This recognition promoted a tourist and real estate boom in the Centro Histórico and, as a result, its inhabitants have faced gentrification dynamics that are expelling them to other areas of the city. During the last 15 years, these dynamics have shown a strong acceleration. Therefore, the Centro Histórico is experiencing, on the one hand, huge inflows of capital for the purchase of properties …


Micromending The Metabolic Rift: An Analysis Of Food Waste Composting Systems In Lexington, Kentucky, Casey Byrd Jan 2021

Micromending The Metabolic Rift: An Analysis Of Food Waste Composting Systems In Lexington, Kentucky, Casey Byrd

Theses and Dissertations--Geography

The metabolic rift theory explores materials and social exchanges between rural and city communities and human-nature relations. Metabolic rifts can exist both environmentally and socially and are often geographically or culturally unique. Ultimately the metabolic rift is earmarked by increasing disconnection between humans and their environment. This thesis draws upon life cycle analysis studies, social-economic studies, and environmental and sustainability studies to argue that large-scale contemporary urban composting efforts, although well intended, are insufficient to mitigate the effects of the metabolic rift. Mobilizing theories around capitalism and the metabolic rift, this research paper connects social, environmental, and economic notions of …


Bio-Spatial Policing In Theory And Practice: Examining Impacts And Resistance Through Mobilities And Children's Everyday Life, Emily Kaufman Jan 2021

Bio-Spatial Policing In Theory And Practice: Examining Impacts And Resistance Through Mobilities And Children's Everyday Life, Emily Kaufman

Theses and Dissertations--Geography

Despite decades of reforms and technological innovations, increasing evidence shows that state securitization disproportionately harms already racially, spatially, and socio-economically marginalized communities. My research investigates uneven impacts of state securitization, from punitive welfare programs to school surveillance to policing. Across sites, I focus on scales, voices and the everyday lived experiences often left out of scholarly discourse and sensational media. In the current climate of growing awareness and scholarship on police violence, my dissertation addresses three less-studied areas: 1) the interplay between racial, gendered, spatial, and technified police practices; 2) how these practices impact the everyday lives of those racially …


Building Quality? Migration, Suzhi, And Subaltern Masculinity In The Shanghai Construction Industry, Leif Johnson Jan 2021

Building Quality? Migration, Suzhi, And Subaltern Masculinity In The Shanghai Construction Industry, Leif Johnson

Theses and Dissertations--Geography

This doctoral dissertation providesa novel perspective on the everyday lives of construction workers in urban China, demonstrating the underpinnings of urban infrastructure and citizenship policy in affective and gendered relations surrounding the construction industry. Drawing on 18 months of ethnographic fieldwork in Shanghai, China, this dissertation makes a series of three related arguments: First, focusing on the role that migrant labor plays in the construction of urban infrastructure in Shanghai, I argue that the physical existence of infrastructure itself is inextricably tied to systems that govern rural-urban migration across China. Second, building from the Chinese concept of suzhi as both …

A Short Text Classification Method Based On Convolutional Neural Network And Semantic Extension, Haitao Wang, Keke Tian, Zhengjiang Wu, Lei Wang

Faculty Publications

In order to solve the problem that traditional short text classification methods do not perform well on short text due to the data sparsity and insufficient semantic features, we propose a short text classification method based on convolutional neural network and semantic extension. Firstly, we propose an improved similarity to improve the coverage of the word vector table in the short text preprocessing process. Secondly, we propose a method for semantic expansion of short texts, which adding an attention mechanism to the neural network model to find related words in the short text, and semantic expansion is performed at the …

The Use Of Distraction: Doomscrolling, Losing Time, And Digital Well-Being In Pandemic Space-Times, Jacob Saindon

Theses and Dissertations--Geography

In the space-times of the COVID-19 global health crisis, how have our relationships with smartphones changed? How do popular discourses designate mundane engagements with digital technologies as healthy or unhealthy, and how are these notions of wellness practiced? This thesis draws upon an online survey of smartphone users residing in Kentucky, and a review of marketing, journalistic, and academic literature to establish current understandings of ‘digital well-being’. The paper then analyzes interviews with Kentucky smartphone users who were asked to track their screen time for a one-week period. This project reveals normative conceptions of well-being and the role of smartphone …


Countering ‘Plastic Addicted Subjects’: Power, Essentialized Identities, And Expertise In Thailand, Olivia Carter Meyer Jan 2021

Countering ‘Plastic Addicted Subjects’: Power, Essentialized Identities, And Expertise In Thailand, Olivia Carter Meyer

Theses and Dissertations--Geography

Thailand is considered one of the six most significant contributors to marine plastic pollution in the world. This has led to widespread media attention and condemnation of Thai people as “addicted to plastic,” with little attention paid to how such discourses actually take shape. Drawing from semi-structured interviews with Thai regulatory institutions, grassroots environmental organizations, plastic industry representatives, and recyclers, I analyze the social, political, economic, and environmental processes that shape Thailand’s plasticscapes. I propose a feminist political ecology of plastic waste which attends to people’s lived experiences and perspectives, power relationships underlying discourses that inform the issue, and Thai …

Uncovering Frontier Mythologies: Memorial Landscapes In Minneapolis, Mn, Corrin Turkowitch

Theses and Dissertations--Geography

This thesis analyzes the relationship between settler colonialism and public memory in B.F. Nelson Park, a downtown park in Minneapolis. My focus is the Pioneer statue, a large granite memorial depicting a frontier family in the middle of the park, which I examine through the lenses of race, gender, power, and violence. Using archival and landscape analysis I examine the historical and present built environment of the park and how it relates to white supremacy. Through interviews of two municipal constituencies, I evaluate how these organizations maintain present narratives of European settlement and in turn uphold the monument. This research …


Gentrification And The Black Church: Mitigating Black Suburban Displacement In A Post Covid-19 World, Jordan Mccray Jan 2021

Gentrification And The Black Church: Mitigating Black Suburban Displacement In A Post Covid-19 World, Jordan Mccray

Theses and Dissertations--Geography

Black churches have been playing an important, stabilizing and supportive role for their members, their neighborhoods, and their communities more broadly. However, these churches’ memberships, community functions, and abilities to support their members have been threatened by the accelerating displacement of African Americans due to the ongoing effects of gentrification, defined by massive economic investment in low-income areas leading to the displacement of low-income residents. At the same time, COVID-19 has also changed the ways churches are able to deliver their support and outreach, with some moving their services to be completely virtual, and many outreach programs having to be …

Procuring Produce In A Rural, Appalachian County: A Thematic Analysis Of Community Member Experiences, Caroline Blincoe

Theses and Dissertations--Nutrition and Food Systems

Rates of obesity and other health disparities are exceptionally high in rural Appalachian counties compared to the nation as a whole. One causal factor of these health disparities in Appalachian counties is the inequitable allocation of healthy food. Food insecurity and the local food environment are large drivers for obesity experienced by Martin County, Kentucky residents. Successful socioecological model (SEM) and policy, systems, and environmental (PSE) interventions have shown promising results in reducing obesity and enhancing food security in this population. Through the transcription of semi-structured focus group interviews, thematic analysis aimed to obtain perspectives on the local food system. …
