Prototyping A Social Media Flooding Photo Screening System Based On Deep Learning, Huan Ning, Zhenlong Li, Michael E. Hodgson, Cuizhen Wang

Faculty Publications

This article aims to implement a prototype screening system to identify flooding-related photos from social media. These photos, associated with their geographic locations, can provide free, timely, and reliable visual information about flood events to the decision-makers. This screening system, designed for application to social media images, includes several key modules: tweet/image downloading, flooding photo detection, and a WebGIS application for human verification. In this study, a training dataset of 4800 flooding photos was built based on an iterative method using a convolutional neural network (CNN) developed and trained to detect flooding photos. The system was designed in a way …

Flooding And Industrial Swine Farming In North Carolina: Implications Of Natech Hazards On The Assessment Of Environmental Justice, Jacob Ramthun

Theses and Dissertations

“Natech” events, in which natural hazards trigger anthropogenic hazards, are becoming increasingly common. Methodologies for measuring the impact of natech events on environmental justice assessments are lacking, particularly in rural scenarios. This study used additive, multiplicative, and z-score threshold methods of combining the density of industrial swine farms in eastern North Carolina and the presence of flood risk to determine whether or not natech risk exhibits emergent socioeconomic indicators and whether areas of high natech constitute environmental injustice. The multiplicative and z-score threshold methods generated variables representing natech risk to compare to socioeconomic indicators, as well as statistically significant hotspots. …

A Gis-Based Risk Assessment For Fire Departments: Case Study Of Richland County, Sc, Tracy Whelen

Theses and Dissertations

Risk assessments enable fire departments to be better prepared for future incidents and to engage in more effective prevention activities. A combination of physical, demographic, and behavioral risk factors combined form a community’s level of risk. This research shows how spatial and nonspatial statistical methods can be used within a GIS framework to create such a risk assessment, with the Columbia-Richland Fire Department in Richland County, SC being used as a case study. Hot spot analysis and thematic mapping of incident rates were used to assess the first research question – what is the spatial variability of structure fires, carbon …

“In The Beginning, It Was Little Whispers...Now, We’Re Almost A Roar”: Conceptualizing A Model For Community And Self In Lgbtq+ Health Information Practices, Vanessa Kitzie, Travis L. Wagner, Alexander N. Vera

Faculty Publications

Although LGBTQ+ populations experience significant health challenges, little research exists that investigates their health from an informational perspective. Our study addresses this gap by exploring the health information practices of LGBTQ+ communities in South Carolina, focusing on how sociocultural context shapes these practices. Thirty semi-structured interviews with South Carolina LGBTQ+ community leaders analyzed using open qualitative coding informed the development of a conceptual framework describing their information practices. Findings show that participants engaged in two broad types of practices – protective and defensive – as responses to risks and barriers experienced, which are in turn produced by social and structural …

Flora Annie Steel: The Walter Scott Of The Punjab?, Juliet Shields

Studies in Scottish Literature

Suggests that Flora Ann Steel Steel’s late Victorian historical novels about India, usually discussed in terms of gender, race, or postcolonial criticism, are more usefully compared to Walter Scott than to Rudyard Kipling, arguing that Steel's novels, like Scott’s about Scotland, formalize an understanding of historical change that derives from the Scottish Enlightenment.

Multilevel Analysis In Rural Cancer Control: A Conceptual Framework And Methodological Implications, Whitney Zahnd, Sara L. Mclafferty, Jan M. Eberth

Faculty Publications

Rural populations experience a myriad of cancer disparities ranging from lower screening rates to higher cancer mortality rates. These disparities are due in part to individual-level characteristics like age and insurance status, but the physical and social context of rural residence also plays a role. Our objective was two-fold: 1) to develop a multilevel conceptual framework describing how rural residence and relevant micro, macro, and supra-macro factors can be considered in evaluating disparities across the cancer control continuum and 2) to outline the unique considerations of multilevel statistical modeling in rural cancer research. We drew upon several formative frameworks that …

Testing Predictability Of Disease Outbreaks With A Simple Model Of Pathogen Biogeography, Tad Dallas, Colin J. Carlson, Timothée Poisot

Faculty Publications

Predicting disease emergence and outbreak events is a critical task for public health professionals and epidemiologists. Advances in global disease surveillance are increasingly generating datasets that are worth more than their component parts for prediction-oriented work. Here, we use a trait-free approach which leverages information on the global community of human infectious diseases to predict the biogeography of pathogens through time. Our approach takes pairwise dissimilarities between countries’ pathogen communities and pathogens’ geographical distributions and uses these to predict country–pathogen associations. We compare the success rates of our model for predicting pathogen outbreak, emergence and re-emergence potential as a function …

Chronic Kidney Disease From Non-Traditional Causes Throughout Central America, Abigail K. Watson

Senior Theses

Throughout many Central American countries, incidence of chronic kidney disease (CKD) has been on the rise. The disease mainly affects agricultural workers and differs from typical CKD. Patients in these countries often do not have preexisting conditions such as diabetes or hypertension known to be traditional causes of CKD. They also experience increased damage to the kidney tubules, rather than the glomeruli generally more heavily impacted. There has been speculation regarding the causes of CKDnT (chronic kidney disease of nontraditional causes), but no consensus has been reached. Two major hypotheses to explain the high prevalence among Central American sugarcane workers …

Understanding The Spatiotemporal Development Of Human Settlement In Hurricane-Prone Areas On The Us Atlantic And Gulf Coasts Using Nighttime Remote Sensing, Xiao Huang, Cuizhen Wang, Junyu Lu

Faculty Publications

Hurricanes, as one of the most devastating natural hazards, have posed a great threat to people in coastal areas. A better understanding of the spatiotemporal dynamics of human settlement in hurricane-prone areas largely benefits sustainable development. This study uses the nighttime light (NTL) data from the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP/OLS) to examine human settlement development in areas with different levels of hurricane proneness from 1992 to 2013. The DMSP/OLS NTL data from six satellites were intercalibrated and desaturated with the Advanced Very High Resolution Radiometer (AVHRR) and Moderate Resolution Imaging Spectroradiometer (MODIS) optical imagery to derive …

Distribution And Abundance Of Vibrio Parahaemolyticus In Surficial Estuarine Sediment From North Inlet, Sc, Usa, India Briana Gartmon

Theses and Dissertations

Vibrio parahaemolyticus is a ubiquitous coastal organism that causes gastroenteritis (vibriosis) after ingestion of mishandled or undercooked seafood. Cases of vibriosis have increased rapidly in the past decade. V. parahaemolyticus densities have historically been associated with an increase in sea surface water temperatures, but recent shellfish bed closures in fall and winter months in cooler regions (the Baltic Sea, the Pacific NW, and New England) suggest that there may be additional environmental parameters that affect densities of V. parahaemolyticus. The vertical distribution of V. parahaemolyticus was assessed in the pristine North Inlet Estuary (SC, USA). The goal of this …

Distribution And Dispersal Potential Of The Endemic Tree Loblolly Bay (Gordonia Lasianthus) In The Southeastern United States Coastal Plain And Implications For Conservation In The Context Of Forecast Climate Scenarios., Herrick Hermann Klaus Brown

Theses and Dissertations

Plant communities in the Southeastern United States Coastal Plain constitute a rich assemblage of species from neighboring floristic provinces and include over 1,000 species endemic to the region. Conservation of these unique landscapes requires a better understanding of potential impacts from human activity and a changing climate. As a model species, the endemic tree Loblolly Bay (Gordonia lasianthus) is representative of Carolina Bays, pocosins, and isolated wetland habitats that accentuate Longleaf Pine ecosystems which dominate the focus area. Seed-dispersal events in Loblolly Bay are limited to periods of relatively low humidity primarily during the months of October to December, and …

Language Nests On The Move: The Case Of Võro Pre-Primary Education In Estonia, Kara D. Brown, Mariko Faster

Faculty Publications

This article considers the circuitous route of knowledge exchange from South (New Zealand)-to North (Finland)-to regional South (Estonia) by examining the development of Võro language nests (keelepesä) in Estonia. Language nests reflect the global nature of educational knowledge exchange as well as the importance of networks of languageresearchers and activists in this policy inspiration. Estonia is a fascinating case for understanding the international spread and local development of the language-nest approach in a post-Socialist context. The authors draw on concepts of policy borrowing and diffusion and the “grammar of schooling” to explore the spread of the language nest approach and …

Complicating The Narrative: Using Jim's Story To Interpret Enslavement, Leasing, And Resistance At Duke Homestead, Jennifer Melton

Theses and Dissertations

In the antebellum South, an enslaved person was more likely to be leased out than to be sold during his or her lifetime. Despite its ubiquity, leasing of enslaved people is rarely interpreted at historic sites and is not widely understood by the general public. In this project, I examine leasing and resistance to slavery in North Carolina through the lens of Jim, an enslaved man leased by Washington Duke at the property that is now Duke Homestead State Historic Site. While Duke is famous in North Carolina as founder of the American Tobacco Company, he was a yeoman tobacco …

Learning The Land: Indians, Settlers, And Slaves In The Southern Borderlands, 1500-1850, William Cane West

Theses and Dissertations

Between 1500 and 1850, Native Americans, Europeans, and enslaved African Americans competed for territory within the landscape of the lower Arkansas Valley. The complex transitional environment between delta bottomlands, interior highlands, and Great Plains fostered the co-existence of competing Native and Euro-American claims to regional sovereignty and settlement well into the nineteenth century. The geopolitical divides often hinged on debates over environmental resources and scientific practices. Indigenous polities from the Mississippians to the Quapaws and Osages adapted to environmental changes to establish and maintain their borders in the face of European colonial presence. In the nineteenth century, Cherokees and white …

Emerging Populations: An Analysis Of Twenty-First Century Caribbean Short Stories, Jeremy Patterson

Theses and Dissertations

The Caribbean has always been a contested space, a space difficult to define, and the literary genre of the short story has always been difficult to define as well. As a region and as a genre, what they share is less prestige, and less development, than other regions and genres. This dissertation brings both of these elements together in a comparative literature study of three twenty-first century Caribbean short story anthologies from the three major linguistic traditions of the Caribbean (English, French, and Spanish). The distinguishing characteristic of these short stories, and the overarching framework for this study, is that …

Analysis Of Hpv16 Variants In The Carolina Women’S Care Study And A Comparison Of Gene Expression Profiles Of Exfoliated Cervical Cells From Women Who Either Clear Or Do Not Clear An Hpv16 Infection, Erica Shirlene Green

Theses and Dissertations

Human papillomavirus (HPV) is the etiologic agent for cervical cancer with HPV type 16 (HPV16) being found in about 50% of cervical cancers worldwide. HPVs vary in genomic (DNA) sequence not only between types, but also within types, known as variants. Variants of a particular HPV type may differ by up to 2% in nucleotide sequence in the coding region and up to 5% in the noncoding region. Variants within HPV16 have been identified and grouped into six distinct phylogenetic branches, which segregate geographically: European (E), Asian-American (As.A), African-1 (Af-1), African-2 (Af- 2), Asian (As), and North American (NA). However, …

Innovative Approaches Using Multispectral Imagery To Detect Nearshore Bars And Elucidate Beach-Dune System Dynamics, Mayra A. Román-Rivera

Theses and Dissertations

Nearshore bars naturally protect the coast against erosion by dissipating wave energy. They are significant reservoirs of sand, and thus, they may impact the response of beaches to different wave conditions. Nearshore bar position and morphologic variability also influences long- and short-term beach and dune stability. This study reveals how nearshore bars influence beach-dune dynamics using very high-resolution (VHR) imagery. A new low- cost identification approach for bar identification was applied by integrating VHR imagery. Future nearshore bar research will benefit from integrating the larger spatial scale provided by satellite sensors. A rule-based OBIA approach was successful in identifying and …

Shelf Inputs And Lateral Transport Of Mn, Co, And Ce In The Western North Pacific Ocean, Peter L. Morton, William M. Landing, Alan M. Shiller, Thomas D. Kelly, Michael Bizimis, John R. Donat, Eric H. De Carlo, Joseph Shacat

Faculty Publications

The margin of the western North Pacific Ocean releases redox-active elements like Mn, Co, and Ce into the water column to undergo further transformation through oxide formation, scavenging, and reductive dissolution. Near the margin, the upper ocean waters enriched in these elements are characterized by high dissolved oxygen, low salinity, and low temperature, and are a source of the North Pacific Intermediate Water. High dissolved concentrations are observed across the Western Subarctic Gyre, with a rapid decrease in concentrations away from the margin and across the subarctic-subtropical front. The particulate concentrations of Mn, Co, and Ce are also high in …
