Modis-Based Fractional Crop Mapping In The U.S. Midwest With Spatially Constrained Phenological Mixture Analysis, Cheng Zhong, Cuizhen Wang, Changshan Wu

Faculty Publications

Since the 2000s, bioenergy land use has been rapidly expanded in U.S. agricultural lands. Monitoring this change with limited acquisition of remote sensing imagery is difficult because of the similar spectral properties of crops. While phenology-assisted crop mapping is promising, relying on frequently observed images, the accuracies are often low, with mixed pixels in coarse-resolution imagery. In this paper, we used the eight-day, 500 m MODIS products (MOD09A1) to test the feasibility of crop unmixing in the U.S. Midwest, an important bioenergy land use region. With all MODIS images acquired in 2007, the 46-point Normalized Difference Vegetation Index (NDVI) time …

Potential Range Expansion Of The Invasive Lionfish In The Western Atlantic Ocean, Brian Grieve

Theses and Dissertations

Lionfish (Pterois volitans) are an invasive, predatory fish native to the reefs of the Indo-Pacific. In the mid-1980s, lionfish were introduced off the coast of Miami, FL and have since transformed many of the reef ecosystems throughout the Western Atlantic Ocean. Although lionfish are found year-round as far north as Cape Hatteras, NC, they are confined to the warm Gulf Stream during winter months. Seasonal inshore expansion is possible in the summer, and further poleward expansion is limited by cold bottom-water temperatures in winter. Here, I use an ensemble of 17 different climate models to project lionfish habitat by the …

Building The C-Suite Talent Pipeline: Insights From The 2015 Hr@Moore Survey Of Chief Hr Officers, Patrick M. Wright, Matthew L. Call, Anthony J. Nyberg, Donald J. Schepker, Michael D. Ulrich

Reports

The HR@Moore Survey of Chief HR Officers probed 143 CHROs regarding their strategies for building the C-suite talent pipeline. CHROs reported that they place the greatest importance on practices aimed at developing this talent, followed by those focused on retaining this talent. Specifically, firms provide individuals in the C-suite talent pipeline with significant access to the senior leadership of the firm, so that these individuals can begin to understand C-suite roles and so firm leaders can assess individuals in the talent pipeline. CHROs also emphasize using stretch assignments/job rotation and special projects as means of both developing broader skills/perspectives and …

Tree-Sway Frequency And The Turbulent Co-Spectral Gap In A Dense Canopy Environment, Katherine L. Ertell

Theses and Dissertations

Today, knowledge of canopy turbulence comes solely from field observations. However, measurements or field observations that are taken at a specific location within the canopy cannot accurately capture the interaction of the wind and the canopy it crosses. Without this complete picture of the atmosphere, the temporal fluctuations that exist in turbulent flows cannot be understood. From an atmospheric perspective, the complex structure of forests significantly influences turbulence in the atmospheric boundary layers (ABL) by consistently imposing both mechanical and thermal forces. This study explores the temporal and spatial characteristics of tree-sway motions and their aerodynamic interactions with coherent turbulence …

Of Wilderness, Forest, And Garden: An Eco-Theory Of Genre In Middle English Literature, Barbara L. Bolt

Theses and Dissertations

“Of Wilderness, Forest, and Garden: An Eco-Theory of Genre in Middle English Literature” proposes a new theory of genre that considers the material elements of the natural environment in Middle English literature composed between 1300-1450 CE. Instead of treating the setting as just a backdrop for human activity, I posit that the components of the environment play a role in the deployment of the narrative by shaping the characters and influencing the action. More than an acknowledgement of the particular natural features, this study explores the role that these components play and how they give us a deeper understanding of …

The Liberal Commercial Peace, Regional Considerations: International Relations Of Southeast Asia, Latin America, And The European Union Countries, Chienwu Hsueh

Theses and Dissertations

Most of the large-N empirical studies on the liberal commercial peace theory demonstrate that, in general, trade has a robust pacifying effect in reducing the probability of dyadical militarized interstate disputes. However, why trade’s pacifying effect varies across time and space remains a puzzle that previous research has not yet solved. The liberal commercial peace literature suggests the following questions are in need of answers: Why does trade promote peace mainly in inter-region dyads but not in intra-region dyads? What are the preconditions that make trade’s pacifying effect work or not work? In this research, I argue that there are …

The Sensory Environments Of Civil War Prisons, Evan A. Kutzler

Theses and Dissertations

The dissertation explores the experiences of four hundred thousand Union and Confederate prisoners during the American Civil War. While much has been written on the overlapping experiences of soldiers, civilians, and slaves, less attention has been paid to those behind masonry walls or wooden stockades. The premise of the dissertation, borrowed from the theory and methodology of sensory history, is that while human sensory physiology changes slowly over time, perception is fluid and varies by time, place, and culture. Drawing from nearly two hundred unpublished manuscripts as well as newspapers, government records, and postwar narratives, this dissertation explores the experiences …

Mobile Home Resident Perspectives On Preparedness, Protective Action, And Evacuation For Tornado Hazards, Kevin D. Ash

Theses and Dissertations

More than 1,000 tornadoes strike the United States each year, and no population segment has been impacted to a greater degree than those who live in mobile homes. Despite being only about 7% of the total population, mobile home residents have comprised 40% to 50% of all tornado deaths over the past fifty years. Inhabitants of mobile homes must therefore act quickly to protect themselves when they are threatened by tornadoes. Warning messages instruct mobile home occupants to move to a sturdier building until the storm passes, but what are the residents’ perspectives on this recommended behavior? It is unknown …

Closing The Revolving Door: A Preliminary Investigation Of The Efficacy Of A Community Of Practice Including A Same Subject Mentor Using Social Media In Increasing The Retention Rates Of Induction Year Secondary Mathematics Teachers, Beth Rexroad Oliver

Theses and Dissertations

Only recently, the well-documented shortage of secondary mathematics teachers is being attributed to retention. Wenger’s Communities of Practice (CoPs) and the provision of same subject mentors have been shown to provide teachers with support, opportunities to collaborate, and a reduction in their feelings of isolation – all factors known to impact retention positively. The rapid advancement and prevalence of online social media provide easily accessible, cost effective means to connect teachers with each other and with same subject mentors.

This study investigated the primary question: What, if any, is the relationship between the retention of first-year secondary school mathematics teachers …

Boundary Stones: Morbid Concretions And The Chemistry Of Early Nineteenth Century Medicine, Edward Allen Driggers Jr.

Theses and Dissertations

My dissertation is the story of communities of physicians seeking to understand the morbid concretion of the body using the new chemistry from the late eighteenth century. Morbid concretions, or calculi, were occurred in the urinary passages, lungs, joints, pancreas, uterus, and other areas of the body. At the turn of the nineteenth century, some physicians saw analytical chemistry, emerging out of the so-called chemical revolution, as applicable in understanding and treating stone-based diseases. However, some physicians and surgeons saw the treatment of stones with chemistry as evidence of the need to return to older practices of medicine, like humoral …

Economic Losses And Extreme Tornado Events, Rachel Reeves

Theses and Dissertations

Research on tornado impacts has previously focused mainly on analyzing the deaths and injuries associated with tornadoes. While economic loss from multiple hazards is a well-researched field, little has been done to assess the economic losses sustained during tornado events. Additionally, the literature regarding the Enhanced Fujita scale’s comparability to the Fujita scale is limited. This research aims to add to the literature by statistically analyzing the two tornado scales, determining the movement of tornadoes over time using a cluster analysis, comparing the location of extreme tornadoes to those which produce extreme loss, and looking at the statistical relationship between …

The Meaning Of Place Recovery On The Mississippi Gulf Coast, Ronald L. Schumann, Iii

Theses and Dissertations

Recovery is a post-disaster period of adjustment when individuals, households, neighborhoods, and communities work to overcome the effects of a disaster and regain functionality. Recovery is a multi-scalar process whose outcomes are manifested in the physical landscape; however, assessments of the meaning, progress, and outcomes of recovery are specific to individuals who view the landscape from an embodied perspective within the local social hierarchy. Common recovery measurement techniques used by emergency managers, planners, local leaders, and hazards scholars approximate recovery with reconstruction of physical infrastructure or repopulation of residences. These longitudinal quantitative proxies may claim to represent the status of …

Institutional Resilience Along The Mississippi Gulf Coast In The Context Of Pre- And Post-Hurricane Katrina, Khai Hoan Nguyen

Theses and Dissertations

Building resilience to disasters helps reduce loss of life and property, allowing communities to recover more quickly from shocks and disruptions. Governing institutions are tasked with tremendous responsibility in terms of mitigating risks and enhancing resilience of local communities through proactive planning and policies. It is important to examine how institutional policies have changed pre- and post-disaster to determine their contribution to community resilience. Metrics and indicators can be used to quantitatively assess, establish baseline, track, and monitor resilience at the community level. Few studies have attempted to measure institutional resilience using a set of indicators and metrics, and even …

Ammonium Concentrations Above A Louisiana Sugarcane Field, Wesley Robert Skeeter

Theses and Dissertations

High concentrations of ammonium (NH4+) aerosols can lead to acidification of soils, forest decline, and eutrophication of water ways (Aneja et al. 2003). NH4+ along with its precursor ammonia (NH3) forms a complicated gas aerosol system that is poorly understood and requires further research. Rotating annular denuder systems actively sampled NH4+ from the northern corner of a sugarcane field at 2.89 m and 5.18 m above the northern corner of a sugarcane field in St. Gabriel, Louisiana over 31 days and 31 nights between May 25th and July 27th of 2011. These data were used to calculate the average NH4+ …

Geographic Accessibility To Health Services And Neonatal Mortality Among Very Low Birthweight Infants In South Carolina, Portavia Featherstone

Theses and Dissertations

Introduction: Infant mortality is commonly denoted as a marker of population health with more than half of all infant deaths occurring during the neonatal period (0-27 days) of infancy. Mortality for infants born very low birthweight (<1500 grams) is markedly higher than the babies born with normal birthweight (2500-4000 grams). The purpose of this research project was to assess geographic access to perinatal health services and the risk of neonatal death among infants born with very low birth weight. Data and methods: The linked birth and death records of a retrospective cohort of very low birthweight (<1500 grams) infants born in South Carolina between the years 2010 and 2012 were used (n=3191). We assessed the impact of travel time from maternal residence to delivery hospital and travel time from maternal residence to the nearest prenatal care provider (obstetricians/gynecologists, community health center, or rural health clinic). Logistic regression modeling was performed with adjustments for maternal characteristics (race, age, chronic/gestational hypertension, chronic/gestational diabetes mellitus, smoking, prenatal care), newborn characteristics (gestational age, birthweight, gender, NICU admission at birth), and the birth in a level III hospital. Results: There were a total of 563 neonatal deaths in this population and the neonatal mortality rate was 17.64 neonatal deaths per 100 live births. We did not find significant associations of travel time from maternal residence to delivery hospital and to a closest prenatal care provider with neonatal death after adjusting for confounders. However, we found that a one-week increase in gestational age (OR: 0.61 [95% CI: 0.57-0.65]) and non-Hispanic Black mothers (versus non-Hispanic White mothers) (OR: 0.65 [95% CI: 0.45-0.94]), were associated with the lower odds of neonatal death, while non-NICU admission at birth (OR: 5.99 [95% CI: 4.05-8.84]) was associated with an increased odds of neonatal death. Conclusion: Although we did not find that travel time was associated with neonatal mortality among very low birthweight infants, our study identified a few significant correlates for neonatal deaths in this birthweight group. Future studies should investigate the role of geographic access to care on mortality during other periods of infancy and among other birthweight groups.

A Tale Of Two Landscapes: Examining Alienation And Non-Visitation Among Local African American Fishers At Congaree National Park, Janae Davis

Theses and Dissertations

The Wilderness Act of 1964 limits acceptable activities in federally designated wilderness areas to those associated with leisure, scenic viewing, education and scientific inquiry. These stipulations, which privileged the interests of the early environmental movement’s elite white leaders and disregarded uses valued by racial/ethnic minorities and working class groups, continue to inform wilderness management in national parks. This legacy of exclusion is evidenced by national park visitation statistics showing overrepresentation1 of whites and underrepresentation of African Americans (Meeker, Woods, & Lucas, 1973; P. A. Taylor, Grandjean, & Gramann, 2011). The purpose of this study is to understand how wilderness management …

Institutional Adaptation And Drought Management In The Carolinas, Kirsten Lackstrom

Theses and Dissertations

Drought is one of the costliest hazards faced by the United States, having caused billions of dollars in damage and affected all regions of the country over the past two decades. There have been many efforts to strengthen society’s technical and managerial capacity to respond to drought, mitigate risks, and adopt proactive planning and management strategies. Advances entail the adoption of drought plans, improvements to data collection and monitoring systems, and development of networks to disseminate information and foster communications. Despite recent progress, response remains reactive and crisis-oriented. Management is often uncoordinated across the multiple sectors and fragmented jurisdictions affected …

Historical Violence And Modernist Form In Zoe Wicomb's David's Story, Kaelie Rianne Giffel

Theses and Dissertations

The essay brings together Zoe Wicomb’s David’s Story with Walter Benjamin’s “Theses on the Philosophy of History” and (less centrally) Julia Kristeva’s work on “Women’s Time.” I argue that, while Derek Attridge claims that the novel’s modernism emerges from its interrogation of historical crisis, David’s Story is modernist because of its experimentation with nonlinear narrative and an engagement with modern intertexts such as Heart of Darkness and Ulysses. Benjamin’s “Theses on the Philosophy of History” illuminates the structure of Wicomb’s novel, which creates what Benjamin calls a “constellation” of stories that are non-causally yet historically related to each other. …

"This Is A Little Beauty": Preserving The Legacy Of The Columbia Cottage, Kayla Boyer Halberg

Theses and Dissertations

In 1965 the built environment of the city of Columbia, South Carolina, was in a state of flux. An active urban renewal campaign existed in the city for nearly a decade prompting a reactionary historic preservation movement. Upon a collaborative recommendation from the Historic and Cultural Buildings Commission and the Historic Columbia Foundation, City Council hired architectural historian Dr. Harold N. Cooledge to conduct an architectural and feasibility survey. In his report, Cooledge identified the Columbia Cottage, a vernacular form widespread throughout the historic neighborhoods of South Carolina’s capital city. His use of the term “Columbia Cottage” to label the …

Crabgrass Piety: The Rise Of Megachurches And The Suburban Social Religion, 1960-2000, Nathan Joseph Saunders

Theses and Dissertations

Although there were less than twenty megachurches (churches averaging over two thousand in weekly attendance) in the United States before 1960, by 2010 there were approximately fifteen hundred. Megachurches are not a homogenous group, but they exist in all parts of the country and they have enough in common to warrant their identification as part of a coherent trend in American evangelical culture. Specifically, most megachurches appeal to an ethos that emerged in the 1970s and 1980s known as the suburban social religion. The suburban social religion combined to differing degrees the American civil religion described by Robert Bellah, meritocratic …

Beyond Science And Hysteria: Reality And Perceptions Of Environmental Justice Concerns Surrounding Marcellus And Utica Shale Gas Development, Ann M. Eisenberg

Faculty Publications

The debate surrounding the use of hydraulic fracturing (also known as “fracking” or “HF”) to extract natural gas from the Marcellus and Utica shale deposits is often characterized as a tension between economic development and environmental risks. But frequently missing from this dichotomy is the fact that the concerns of many who oppose HF use extend beyond the purely “environmental,” and also include concerns about issues such as “the natural resource curse” and losing autonomy. These concerns ring of “environmental justice” rather than “environmentalism.” Environmental justice espouses the belief that no group should bear disproportionate environmental consequences resulting from industrial …

Dissolved And Particulate Phosphorus Distributions And Elemental Stoichiometry Throughout The Chukchi Sea, Meryssa Piper

Theses and Dissertations

As the only gateway of material, particularly nutrients, from the Pacific to the Arctic Ocean, the biological and chemical transformations that occur within the Chukchi Sea are critical for understanding Arctic ecosystems. This study examines the biogeochemical cycling of the macronutrient phosphorus (P) relative to carbon and nitrogen in the eastern Chukchi Sea during the ICESCAPE’s mission. Sea ice and water column dissolved and particulate phosphorus samples were collected during two summer expeditions in 2010 (n=593) and 2011 (n=989). Despite being a landlocked marginal sea, the P pool present within the Chukchi Sea was substantially modified by biological processes with …

Negotiating The Interconnections Of Sociality, Identity, Fan Activism And Connectivity Within The Twilight Community, Amy A. O’Brien

Theses and Dissertations

In my dissertation, “Negotiating the Interconnections of Sociality, Identity, Fan Activism and Connectivity within the Twilight Community”, I examine the ways in which women employed a shared interest in a cultural text to establish meaningful social relationships with other fans. Rather than focusing solely on consumptive pleasure, these fans of the Twilight series utilized the intense popularity of the franchise to engage in charitable activities. Through these common threads of identity, community, virtual technologies, and charity, I contend that the Twilight fandom represents a new form of fan community, which is trending upward and creating an impact beyond the traditional …

The Turkish Foreign Policy Under The Justice And Development Party (Akp): A Paradigm Shift?, Ali Demirdas

Theses and Dissertations

Understanding the Turkish foreign policy has become even more important in recent years given the developments surrounding the country. Furthermore, the last decade witnessed a radical change in the Turkish foreign policy making under the Justice and Development Party (AKP).

This dissertation aims to explain the nature of this change based on the application of the Policy Paradigms Theory, comparing the components of the AKP foreign policy understanding with those of the Kemalist, the status que paradigm that defined the foreign policy making in Turkey well into the early 21st century. The application of the theory provides evidence, based on …

Theses and Dissertations

Drawing on literature from public relations, marketing, interpersonal communication, and organizational communication, this dissertation focused on the effects of authenticity on relationship management outcomes in nonprofit organizations’ social media efforts. There is significant need for relationship management rooted in authenticity with the rise in inauthentic communication online. This dissertation aims to contribute to relationship management theory by highlighting the role of control mutuality in analyses of authenticity in organization-public relationships in social media for nonprofit organizations like local animal welfare organizations. This dissertation proposes that control mutuality is an ethical outcome of authentic relationship management. This dissertation also proposes that …

Telling A Different Narrative: Exploring The Values And Challenges Of Performing Enslaved Community Members’ Stories At U.S. Southern Plantation Museums, Stefanie Kate Benjamin

Theses and Dissertations

Informed by both performance studies and collective memory theory, this study centers around Let Them Be Heard, a theatrical production that breathes life into the narratives of former slaves, performed at three plantation sites in the U.S. South. I seek to understand the lived experience of the performance through the eyes of three key stakeholder groups (plantation museum curators and docents, the director of the Let Them Be Heard production, and the show’s performers), and the impact of the performance on those individuals and on the plantation sites where the performances took place. Ultimately, I am attempting to discern the …

To exploit these properties for practical applications a large area high quality graphene, transferred on appropriate substrates, is required. In this work, high quality single monolayer graphene (determined from Raman spectroscopy) has been synthesized by chemical vapor deposition (CVD) technique for …

Knowing In America: The Enlightenment, Science, And The Early Republic, Timothy K. Minella

Theses and Dissertations

This dissertation analyzes practices of science and technology in the early United States as windows onto the American Enlightenment. Although scholars have emphasized the important impact of Enlightenment thought on the American founding, the historiography tends to argue for the decreasing influence of the Enlightenment on American culture as the nineteenth century progressed. In addition, scholars tend to see a decline in American science after Benjamin Franklin as nineteenth-century Americans began to focus primarily on the practical problems of everyday life. I question these interpretations by connecting scientific practice in the Early Republic with transatlantic Enlightenment thought and analyzing American …
