An Assessment Of Technology Adoptability In Sugarcane Burning Smoke Plume Mitigation, Sara Flecher

Theses and Dissertations

The adverse health effects of sugarcane burning emissions on surrounding communities are well documented. Sugarcane farmers in Louisiana, a major sugarcane producing state with 385,000 acres dedicated to sugarcane farming throughout, attempt to mitigate the effects of burn emissions by estimating the characteristics of the resultant smoke plume using meteorological variables as parameters. The current mitigation method designed by the LSU AgCenter, the American Sugar Cane League, and the Louisiana Department of Agriculture and Forestry is a manual process requiring the tedious look-up of atmospheric variables from multiple sources and physically drawing a predicted smoke plume on a paper map, …

Contested Identities And Language Education: Inculcating Nationalist Ideologies In The Basque Region, William Joseph Hogan

Theses and Dissertations

Nationalist sentiment has a long history in the Basque regions of northern Spain. Culturally separate from the dominant Castilian society, separatists have for many years advocated for an independent Basque state. Following democratic reforms under the Constitution of 1978, regional cultures and languages were explicitly recognized and protected in Spain. This allowed for the current set of language laws in the Autonomous Community of Pa├â┬¡s Vasco in which Castilian Spanish and the Basque language of Euskara are held in equal status and recognition. Furthermore, Euskara has been recognized as a defining characteristic of Basque identity. The regional government has instituted …

A Geographic Modeling Framework For Assessing Critical Infrastructure Vulnerability: Energy Infrastructure Case Study, Leanne Sulewski

Theses and Dissertations

Vulnerability of critical infrastructure systems is of the utmost importance to a nation's national security interests, especially the electric grid. Despite the importance of these systems, disruptions continue to occur at an alarming rate, thus indicating that there is a fundamental flaw in the way critical infrastructure systems are analyzed for vulnerability.

Critical infrastructure systems are typically analyzed using mathematical approaches such as graph theory, which strip systems of their important geographic information, and only look at their connections to each other. While these relationships and metrics provide useful information, they cannot provide the entire picture. As such, this research …

Spatial And Temporal Characterization Of A Cold Seep-Hydrate System (Woolsey Mound, Deep-Water Gulf Of Mexico), Antonello Simonetti

Theses and Dissertations

Cold seeps are areas where methane is transferred from the lithosphere into the hydrosphere, accounting for the major source of hydrocarbons in seawaters. Formation of gas hydrate in cold seeps modulates the global discharge of methane to the environment. However, cold seeps are dynamic settings where hydrates dissociate on short and long time-scales triggering substantial methane fluxes to the oceans. These methane vents sustain unique ecosystems at the ocean floors and contribute to ocean acidification. Also, the methane can potentially reach the sea surface and be exchanged with the atmosphere contributing to global warming. Understanding how cold seep-hydrate systems (CSHSs) …

Eco-Epidemiology Of Eastern Equine Encephalitis Virus, Patrick Vander Kelen

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Eastern Equine Encephalitis virus (EEEV) is an alphavirus with high pathogenicity in both humans and horses. Florida continues to have the highest occurrence of human cases in the USA, with four fatalities recorded in 2010. Unlike other states, Florida supports year-round EEEV transmission. This research uses Geographic Information Science (GIS) to examine spatial patterns of documented sentinel seroconversions and horse cases in order to understand the relationships between habitat and transmission intensity of EEEV in Florida. Sentinel sites were categorized as enzootic, periodically enzootic, and negative based on the amount of chicken seroconversions to EEEV. Sentinel sites were analyzed …

World Heritage Status, Governance And Perception In The Pitons Management Area, St.Lucia, Vernice Camilla Hippolyte

There are currently 962 geographic sites in the world that have been classified as World Heritage. World Heritage is a unique concept, privy to and defined by UNESCO-- the United Nations, Educational, Scientific and Cultural organization, one of the specialized agencies and autonomous organizations established within the UN-United Nations system. World Heritage is governed by an international treaty called the Convention Concerning the Protection of the World Cultural and Natural Heritage, adopted by UNESCO in 1972 (The `Convention'). The inscription of a World Heritage Site or designation of World Heritage Status is highly coveted and considered in UNESCO parlance to …

Factors Influencing The Capacity Of Communities To Respond To Coastal Erosion In The Upper Gulf Of Thailand, Chatchai Intatha

Theses: Doctorates and Masters

Local communities must have a capacity to ameliorate coastal erosion impacts. Since coastal erosion operates over long time frames, understanding this capacity, or the abilities of communities to respond to the impacts and recover to maintain community functions, requires analysis of the past and the present. This study explores factors which influence the capacity of communities to respond to coastal erosion and conversely how exposure to coastal erosion itself affects community capacity.

Mixed methods research was used to investigate the views of respondents in seven coastal villages in the upper Gulf of Thailand, three from an area that has experienced …

Applying The Principles Of Spatial Modelling To The Management Of Biodiversity In The Fragmented Landscapes Of South-Western Australia, Shaun Molloy

Theses: Doctorates and Masters

Biodiversity conservation throughout the world is challenged by the impacts of a changing climate on fragmented landscapes. To mitigate these threats, conservation managers require models which can demonstrate the consequences of both negative impacts and management actions. This need can be addressed through spatial modelling applications. Unfortunately, throughout much of the world, spatial modelling is forgone, being seen as requiring skills and resources beyond the means of many conservation planners and managers. This thesis seeks to address this dilemma by delivering criteria for a successful modelling application and by providing case studies which demonstrate how appropriate modelling can be undertaken …

Review Of Digital Detroit: Rhetoric And Space In The Age Of The Network, Timothy Barney

Rhetoric and Communication Studies Faculty Publications

In 1971, rogue Wayne State geographer William Bunge (placed on a federal list of dangerous intellectuals) published Fitzgerald: Geography of a Revolution, a radical polemic about how everyday citizens of a Detroit ghetto could challenge oppression and become geographers of their own neighborhoods. Forty years later, Jeff Rice (formerly a Wayne State professor himself) revisits Detroit geography, but this time largely from his laptop (and without, I hope, the same kind of federal harassment). For while Bunge’s Fitzgerald and Jeff Rice’s Digital Detroit share similar terrain, as well as a love for the city in all its contradictions, …

Hyperspectral Image Classification Using A Spectral-Spatial Sparse Coding Model, Ender Oguslu, Guoqing Zhou, Jiang Li, Lorenzo Bruzzone (Ed.)

Electrical & Computer Engineering Faculty Publications

We present a sparse coding based spectral-spatial classification model for hyperspectral image (HSI) datasets. The proposed method consists of an efficient sparse coding method in which the l₁/l_q regularized multi-class logistic regression technique was utilized to achieve a compact representation of hyperspectral image pixels for land cover classification. We applied the proposed algorithm to a HSI dataset collected at the Kennedy Space Center and compared our algorithm to a recently proposed method, Gaussian process maximum likelihood (GP-ML) classifier. Experimental results show that the proposed method can achieve significantly better performances than the GP-ML classifier when training data …

School of Global Integrative Studies: Faculty Publications

Barbuda is the sister island to Antigua, located in the Lesser Antilles, West Indies. This island belongs to the Miocene arch of the Lesser Antilles, along with Grande Terre of Guadeloupe, Marie Galante, and Anguilla. Barbuda, notwithstanding its small size and low elevation, has an exceptionally rich past. Recent investigations by a Brooklyn College, City University of New York led team, has discovered evidence of human activity in and around these caves from the Archaic Period down to the present day. The range of activity at these caves begins with scatters of Archaic lithics, through artifacts and faunal material possibly …

The Effect Of Visual Wulst Lesions And Trigeminal Nerve Sectioning On The Discrimination Of Magnetic Inclination In The Homing Pigeon (Columba Livia), Merissa Acerbi

Honors Projects

The ability of homing pigeons to return to their loft from unknown places has fascinated scientists for centuries. It is well established that homing pigeons, like migratory birds, posses an innate magnetic inclination compass to determine direction by measuring the angle between the magnetic field vector and the Earth's surface. Recent work has indicated that the avian magnetic compass is light mediated and appears to mediate magnetic information to the brain. This occurs via a visual pathway with processing in the visual Wulst area of the forebrain. There is, however, also evidence from other avian species that magnetic direction may …

Automated Sinkhole Extraction And Morphological Analysis In Northeast Iowa Using High-Resolution Lidar Data, Jonathon Launspach

Dissertations and Theses @ UNI

Accurate and detailed mapping of sinkholes is necessary to ensure sinkhole monitoring and management. Historically, sinkholes were found and digitized manually by a visual examination of aerial photos or through field surveying. This paper develops a new, multicriteria LiDAR-based sinkhole extraction method and automated processes to detect sinkholes and their boundaries. This technique of extraction is unique as it identifies sinkhole boundaries automatically using remotely sensed data, compared to traditional methods of manually tracing the perimeter. A sinkhole detection module was developed within a GIS environment to determine location and boundaries of the sinkholes. Several small study areas were selected …

Scaling Food Security: A Political Ecology Of Agricultural Policies And Practices In Bukidnon, Philippines, Ryan Ehrhart

Dissertations, Theses, and Capstone Projects

Debates over food security strategies in the Philippines have pitted the neoliberal paradigm of trade liberalization, export cropping, and chemical and biotech agricultural methods against the food sovereignty paradigm of protectionism, staple cropping, and sustainable agriculture methods.

The Philippine government has long pushed for yield increases of staples. However, there has been dissonance between governmental desires for rice self-sufficiency and pursuit of a more export-oriented agricultural economy. The World Bank, the International Monetary Fund, the Asian Development Bank, and the World Trade Organization have pressured the government of the Philippines to adopt various tenets of neoliberalism (trade liberalization, privatization, deregulation, …

Determinants Of Neighborhood Exposure To Extreme Heat: A Spatial Examination Of El Paso And Juárez, 2010, Faraj Mohamad Aboargob

Open Access Theses & Dissertations

Numerous studies have been conducted on the modification of local weather by the urban environment. In studying urban environmental effects on the urban heat island (UHI), researchers have investigated influences such as land use, vegetation density, topography, population density, and neighborhood socioeconomic status. Many studies have used data collected from field observations, while other studies relied solely on computer modeling. This Dissertation research used a spatial analysis approach, which has been less widely employed, to investigate neighborhood level biophysical, built environmental and socio-demographic determinants of the El Paso and Juárez UHI. The research utilized inexpensive data obtained from US and …

Summer Land Surface Temperature: Small-Local Variation In Intro-Urban Environment In El Paso, Tx, Mactar Mohamed

Open Access Theses & Dissertations

ABSTRACT

It has been well documented that rapid urbanization and population growth have led to the transformation of the natural landscape into anthropogenic urban land and changed such surface physical properties as albedo, energy balance, and surface roughness. Cities, therefore, will be warmer at the urban areas than the rural lands; this situation creates a phenomenon called Urban Heat Island (UHI).

In the recent decades, numerous approaches to study the variation of land surface temperature during daytime have emerged; however, little is known about the variation during nighttime. This study addressed the spatial variation of Summer Nighttime Land Surface Temperature …

Geography Faculty Publications and Presentations

This project tested the accuracy and repeatability of geomorphic stream channel assessments conducted by two different middle school classes from the Walt Morey Middle School in Troutdale, OR and college students from Portland State University in Portland, OR. Each group surveyed the same three cross-sections in Fairview Creek, a tributary to the Lower Columbia River, in order to assess stream channel geometry, discharge, composition of the bed material, and water quality. The three student groups were all able to accurately document the stream channel geometry, including stream width and mean depth, indicating that these data can be successfully collected by …

Claiming Space, Redefining Politics: Urban Protest And Grassroots Power In Bolivia, Carwil Bjork-James

Dissertations, Theses, and Capstone Projects

This dissertation analyzes the role of space-claiming protests by primarily left grassroots social movements in Bolivia's current political transformation. Space claiming includes mass protests that physically control or symbolically claim urban space through occupations of plazas and roads, sit-ins, blockades, and other measures. As a theoretical construct, space claiming brings together tactics of collective action and meanings of public spaces, and looks at the consequences of their interaction. This dissertation is based on ethnographic engagement and oral interviews with protest participants and their state interlocutors during twelve months of fieldwork and archival research. By using detailed ethnographic evidence--of social life …

An Ice-Core Pollen Record Showing Vegetation Response To Late-Glacial And Holocene Climate Changes At Nevado Sajama, Bolivia, C. A. Reese, K. B. Liu, L. G. Thompson

Faculty Publications

We present the results of pollen analysis performed on an ice core recovered from Nevado Sajama, Bolivia, dated to 25 ka BP. Low pollen concentrations from 25 to 15 ka BP are consistent with the scenario of an expanded ice cap surrounded by sparse vegetation and cold conditions on the Altiplano during the Last Glacial Maximum. After 15 ka BP, more pollen is present and percentages show vegetation response to climate fluctuations during the late Pleistocene. Initially, high concentrations of Poaceae pollen are replaced by Asteraceae pollen, suggesting the occurrence of dry conditions towards the end of the Bolling-Allerod/Guantiva interstadial. …

Critique Of Microcredit As A Development Model, Grace Levin

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

The field of microcredit (otherwise known as microfinance, microlending, or microcapital) has expanded rapidly since the 1980s as an economic means of lifting people out of poverty. Generally, microcredit has been accepted as an effective method for empowering both individuals and communities. In recent years, however, critics have brought to light some of the problems associated with microlending, such as the complex socioeconomic factors that can cause loan programs to fail. These problems stem from the basic tenet of microfinance: the need for lending programs to be managed locally in order to understand the needs of a community and assess …

Factors That Shape Environmental Perceptions: The Role Of Health And Place, Elizabeth Langlois

LSU New Orleans Theses and Dissertations

Risk perception is the judgment people make about the characteristics and severity of a risk. Numerous theories and models exist which have identified the factors that influence risk perception. Among these factors, location, health status, and demographic characteristics are known to shape risk perception. To measure the influence of these factors on environmental perception, a series of surveys conducted in four Louisiana communities between 2004 and 2005 describe community perceptions about environmental issues and health status. The objective of the study was to characterize and compare environmental concerns relative to location, health status, and demographic characteristics. Results indicate that location …

Gender Relations Of Space: Impact On Women’S Leadership In Nigeria [Pilot Study], Oluremi Alapo

Publications and Research

This qualitative phenomenological research study examines women in Nigeria and how they continue to face enormous set-backs regarding development and leadership capabilities. The socio and economic roles that many women occupy in Nigerian society affects leadership roles, especially in the context of sexual division of labor and in decision-making. The national and family culture present prevents women to fully adapt to innovative 21st century leadership. Culture is socialized in a person through the shared values of social groups that in turn play key roles in a person’s cognitive, emotional, and social functioning. The national and family culture is one in …

Monitoring Land-Cover Change In The Las Vegas Valley: A Study Of Five Change Detection Methods In An Urban Environment, Bonnie Diane Weidemann

Theses and Dissertations

Change detection is currently a topic of great interest to theoretic geographic researchers. The necessity to map, monitor, and model land cover change is also important to a variety of applied fields as varied as urban planning and military intelligence. This research compares five algorithms to map urban land cover change in the greater Las Vegas, Nevada metropolitan area. Landsat Thematic Mapper imagery acquired on May 1990 and May 2000 was used as the primary data. The change detection methods yielded simple maps of change vs. no change. These algorithms included image differencing, image ratioing, image regression, vegetation index differencing, …

The Role Of Interdisciplinary Gis And Data Curation Librarians In Enhancing Authentic Scientific Research In The Classroom, Benjamin D. Branch, Michael Fosmire

Libraries Faculty and Staff Presentations

Data science is a recently evolved area of scientific inquiry, where data, often collected by others, is analyzed by independent investigators to draw new conclusions. As such, data literacy needs to be incorporated into authentic research activities. The earth sciences in particular have a trove of data that resides in national data centers as well as individual investigators’ labs, which can be repurposed to provide the inputs for students to make their own inquiries into the data. With the amount of data available, students can make more substantive conclusions than if relying just on data they’ve collected themselves.

The Flow Of Water, Power, And Ideas: Water Commodification In Cape Town, South Africa And The Stratified Experiences Of Time And Space Compression, Jenna Washburn

Master's Theses

I use the neoliberalization of the water sector in Cape Town, South Africa in order to test my theory of unequal development. I assert that the neoliberal economic practices of water commodification, business-friendly tariff policies, and prepaid management devices keep people along the periphery from accessing water, power, and ideas – thus causing a stratification of time and space compression between the core and the periphery.

By painting a theoretical picture of world cities, I wish to complicate the dominant views of time/space compression and suggest that, much like development and arguably because of it, time and space compression actually …

Examining Land Use/Land Cover Change And Potential Causal Factors In The Context Of Climate Change In Sagarmatha National Park, Nepal, Kamal Humagain

Masters Theses & Specialist Projects

In the context of growing tourism and global warming, the fragile landscape of the Himalayas is under immense pressure because of rapid land cover changes in developing countries like Nepal. Remotely sensed data combined with ethnographic knowledge are useful tools for studying such changes. The quantitative change can be measured analyzing satellite images whereas local people’s perceptions provide supportive information. To measure such changes in Sagarmatha National Park of Nepal, Multispectral Scanner (MSS) and Thematic Mapper (TM) images since 1972 were used. Normalized Difference Vegetation Index (NDVI) was calculated for different elevation classes and land cover types. These measurements, along …

Teleconnective Influences On The Strength Of Post-Tropical Cyclones, Jeremy Young

Masters Theses & Specialist Projects

Over the 1951-2009 time period, 47% of all tropical systems in the Atlantic Basin transitioned to post-tropical storms. These storms are capable of producing hurricaneforce winds, torrential, flooding rains and storm surge that floods coastal areas. This study adds to previous climatological work by completing a case-study of Hurricane Ike (2008) and examining how teleconnections such as the El Niño Southern Oscillation (ENSO), the Madden-Julian Oscillation (MJO), the Atlantic Multidecadal Oscillation (AMO) and the Pacific Decadal Oscillation (PDO) contribute to the strength of a transitioning post-tropical storm. T-tests performed show strong statistical relationships between an increase (decrease) in post-tropical storm …
