Role Of Dignity In Rural Natural Resource Governance, Tora Johnson

Electronic Theses and Dissertations

Dignity is “an internal state of peace that comes with the recognition and acceptance of the value and vulnerability of all living things” (Hicks, 2011, p. 1). Dignity is a crucial element in effective governance arrangements. This study applies dignity theory, and related theories of natural resource governance and environmental communication, to understand and overcome barriers to effective governance of common pool resources in rural communities. Chapter 1 reviews relevant literature on natural resource governance and develops a theoretical framework for dignity. Chapter 2 applies dignity theory to a contentious comprehensive planning process in a small Maine town in order …

Spatiotemporal Wireless Sensor Network Field Approximation With Multilayer Perceptron Artificial Neural Network Models, François Neville

Electronic Theses and Dissertations

As sensors become increasingly compact and dependable in natural environments, spatially-distributed heterogeneous sensor network systems steadily become more pervasive. However, any environmental monitoring system must account for potential data loss due to a variety of natural and technological causes. Modeling a natural spatial region can be problematic due to spatial nonstationarities in environmental variables, and as particular regions may be subject to specific influences at different spatial scales. Relationships between processes within these regions are often ephemeral, so models designed to represent them cannot remain static. Integrating temporal factors into this model engenders further complexity.

This dissertation evaluates the use …

Mapping Debris-Covered Glaciers In The Cordillera Blanca, Peru : An Object-Based Image Analysis Approach., Donald J. Biddle

Electronic Theses and Dissertations

Accurate remote-sensing based inventories of glacial ice are often hindered by the presence of supraglacial debris cover. Attempts at automated mapping of debris-covered glacier areas from remotely-sensed multispectral data have met with limited success due to the spectral similarity of supraglacial debris to nearby bedrock, moraines, and fluvial deposition features. Data-fusion approaches leveraging terrain and/or thermal data with multispectral data have yielded improved results in certain geographic regions, but remain unproven in others. This research builds on the data-fusion approaches from the literature and explores the efficacy of object-based image analysis (OBIA) and tree-based machine learning classifiers using Landsat OLI …

Toward A Commons Of Geographic Data, Joseph J. Campbell

Electronic Theses and Dissertations

Making scientific data openly accessible and available for re-use is desirable to encourage validation of research results, and/or economic development. A significant body of spatially-referenced, locally-produced data produced by individual researchers, non-profit groups, private associations, small companies, universities, and non-governmental organizations across the United States is not online and therefore not generally available to professional scientists and to the general public. If there were an online environment, a "Commons of Geographic Data," where that data could be deposited or registered, and where users could access and re-use it, what infrastructure characteristics might potential contributors find desirable in order for them …

Enhanced Place Name Search Using Semantic Gazetteers, Nagalakshmy Vijayasankaran

Electronic Theses and Dissertations

With the increased availability of geospatial data and efficient geo-referencing services, people are now more likely to engage in geospatial searches for information on the Web. Searching by address is supported by geocoding which converts an address to a geographic coordinate. Addresses are one form of geospatial referencing that are relatively well understood and easy for people to use, but place names are generally the most intuitive natural language expressions that people use for locations. This thesis presents an approach, for enhancing place name searches with a geo-ontology and a semantically enabled gazetteer. This approach investigates the extension of general …

Using Kriging, Cokriging, And Gis To Visualize Fe And Mn In Groundwater, Crystal Johnson

Electronic Theses and Dissertations

For aesthetic, economic, and health-related reasons, allowable concentrations of iron (Fe) and manganese (Mn) found present in drinking water are 0.3 mg/L and 0.05 mg/L, respectively. Water samples taken from private drinking wells in the rural communities within Buncombe County, North Carolina contain amounts of these metals in concentrations higher than the suggested limits. This study focused on bedrock geology, elevation, saprolite thickness, and well depth to determine factors affecting Fe and Mn. Using ArcGIS 10.2, spatial trends in Fe and Mn concentrations ranges were visualized, and estimates of the metal concentrations were interpolated to unmonitored areas. Results from this …

Discovering Rock Features With Geophysical Exploration And Archaeological Testing At The Mississippian Pile Mound Site, Upper Cumberland Plateau, Tennessee, Jeremy G. Menzer

Electronic Theses and Dissertations

The Pile Mound survey includes magnetometry paired with targeted ground-penetrating radar (GPR) and electromagnetic induction (EMI) surveys of the mound and testing of associated features over the ca. 6.5 ha site. The GPR survey discovered six rock features (five large rock features within the mound and one marking the outside of the mound). Knowledge of mounds in the Upper Cumberland Plateau (UCP) is lacking—the closest other studied sites are at the Corbin Site, Croley-Evans, Bell Site, and Beasley Mounds, approximately 75 – 100 km away. However, the most similar mound construction is found at Corbin and Cherokee sites, some 175 …

The Effects Of Surf-Driven Development On The Local Population Of Playa Gigante, Nicaragua, Nicholas Harrison William Earhart

Electronic Theses and Dissertations

In many of the world's developing countries, tourism is starting to play a more important role in the improvements of the local and national economies. One of these countries that have started to view tourism as a way to alleviate poverty throughout the country is Nicaragua. With miles of beaches, large swaths of pristine rainforests and beautiful volcanoes, Nicaragua has plenty to offer to travelers from all over the world. One of the sectors of tourism that has rapidly expanded in recent years is that which caters specifically to North American and European surfing tourists, who travel to Nicaragua for …

When Wells Run Dry: Water And Tourism Along The Western Coast Of Nicaragua, Gary Thomas Lavanchy

Electronic Theses and Dissertations

This dissertation uses a political ecology approach to examine the relationship between tourism development and groundwater in southwest Nicaragua. Tourism in Nicaragua is a booming industry bolstered by ‘unspoiled’ natural beauty, low crime rates, and government incentives. This growth has led to increased infrastructure, revenue, and employment opportunities for many local communities along the Pacific coast. Not surprisingly, it has also brought concomitant issues of deeper poverty, widening gaps between rich and poor, and competition over natural resources. Adequate provisions of freshwater are necessary to sustain the production and reproduction of tourism; however, it remains uncertain if groundwater supplies can …

Pedestrian Mobility In Denver: A Mixed Methods Approach, Meghan Elizabeth Mooney

Electronic Theses and Dissertations

This research is rooted in the bigger issues of climate change, urban sustainability, and the drive to make Denver more pedestrian centered despite sprawled conditions. More specifically, this research is driven by (1) the need for a holistic, multi-dimensional, and mixed geographic perspective of pedestrian mobility, (2) the lack of qualitative data regarding pedestrian mobility and (3) a need for a better understanding of the feedback between physical and perceived space and how this influences walking behavior. Given these motivations, I deploy a multidimensional framework for assessing pedestrian mobility in Denver’s Transit Oriented Development (TOD) sites, whereby there are two …

Examining The Spatial Aspects Of Residential Energy Efficiency: Gis And Survey Analysis In Boulder County, Colorado, Walter Stanley Scheib

Electronic Theses and Dissertations

The completion of residential energy efficiency upgrades leads to multifaceted benefits including cost and energy savings, increased household comfort, health benefits, and reduced CO2 emissions. As a result of these benefits, state and local energy efficiency programs across the United States are striving to increase the widespread adoption of energy efficiency upgrades by homeowners. Many program strategies for widespread adoption are informed by case studies of other successful energy efficiency programs. These program strategies would benefit from the additional insight provided by spatial analysis, but a spatial perspective is currently underutilized by energy efficiency programs across the United States. This …

Impacts Of Urban Areas On Vegetation Development Along Rural-Urban Gradients In The Upper Midwest: 2003-2012, Cole Krehbiel

Electronic Theses and Dissertations

Between one-third and one-half of Earth’s land surface has been directly altered by humans, with the remainder comprised of “human-dominated ecosystems” (Vitousek et al. 2008). Earth’s population has surpassed seven billion, projected to increase by 2.5 billion by 2050 in urban areas alone (United Nations 2014). The rapid urbanization of our planet drives global environmental changes in hydrosystems, biodiversity, biogeochemical cycles, land use and land cover, and climate (Grimm et al. 2008). Urban areas alter local atmospheric conditions by modifying surface albedo and consequently evapotranspiration, releasing energy through anthropogenic heat sources, and increasing atmospheric aerosols, leading to increased temperatures in …
