Prehistoric Human Ecodynamics In The Rub Al-Khali Desert: Results Of Remote Sensing And Excavations In Dubai, United Arab Emirates, Jason T. Herrmann

Graduate Theses and Dissertations

Archaeological investigations in the Emirate of Dubai, UAE conducted by the Dubai Department of Archaeology and the University of Arkansas demonstrate that the desert inland of the Oman Peninsula was occupied not only during the Arabian Neolithic (8000-4400 BC), when the region experienced a moist period referred to as the Holocene Climatic Optimum (HCO), but also during the more arid millennia following the decline of the HCO into the Christian Era. During this period, desert settlement clustered near a band of oases, in contrast to the more widespread spatial distribution of remains of nomadic pastoralists from the Neolithic. Excavations at …

Competing Sovereignties: Corporate Social Responsibility, Oil Extraction, And Indigenous Subjectivity In Ecuador, Emily Billo

Geography and the Environment - Dissertations

Corporate social responsibility (CSR) programs developed in recent years as the business response to social and environmental criticism of corporate operations, and are most debated in those societies where neoliberalism emerged most prominently, the United States and the United Kingdom. My dissertation expands these debates investigating the CSR programs of a Spanish-owned multinational oil company, Repsol-YPF operating in the Ecuadorian Amazon region. It explores CSR programs as institutions that can facilitate ongoing resource extraction, and particular technologies of rule that serve to discipline indigenous peoples at the point of extraction. I conducted an institutional ethnography to examine the social relationships …

Returning The Commons: Resource Access And Environmental Governance In San Luis, Colorado, Keith Lindner

Geography and the Environment - Dissertations

In Lobato v. Taylor (2002) the Colorado Supreme Court awarded Hispano heirs to the 1843 Mexican-era Sangre de Cristo Land Grant returned access to formerly communal land known as La Sierra, the Taylor Ranch, or today Cielo Vista Ranch. The 77,000 acre parcel of mountainous land remains privately owned, yet through Lobato over 4,000 individuals have been awarded legal rights to access the land for the "reasonable use" of pastures and forests for grazing, firewood, and timber. Based on roughly 15 months of ethnographic research in collaboration with the Land Rights Council and based in San Luis, CO, this dissertation …

Producing Edge City: Publics, Perceptions, And The Right To Life On The New Frontier, Ben Alan Gerlofs

Geography and the Environment - Theses

This thesis explores Oak Brook, IL, an edge city (Garreau 1991) in the western suburbs of Chicago. A number of authors have advanced criticisms of edge cities (Beauregard 1995; Marcuse 1997), including that they are particularly exploitative and exclusionary. Some authors have claimed that edge cities are a "new frontier" (Garreau 1991), while others suggest that they are nothing new at all (Walker 1994). I address these concerns by way of an in-depth engagement with Oak Brook, Chicago's truest edge city. I ultimately argue that while edge cities have unique characteristics, they are part of a long heritage of capitalist …

Using Gis And Remote Sensing Applications To Determine Recovery From Disaster: Seven Years Post-Katrina In Residential Communities Of Hancock County, Carlton P. Anderson

Honors Theses

Hurricane Katrina devastated the gulf coast states of Louisiana and Mississippi on August 29th, 2005. The communities of Shoreline Park and Waveland in Hancock County, Mississippi were used in this study to analyze land use change post-Hurricane Katrina using Geographic Information Systems (GIS) and Remote Sensing. These two communities are experiencing slower recovery than their counterparts along the coast. By examining high-resolution aerial imagery from 2007 and 2012, there can be comparisons that show the timeline of recovery for these two communities post-Katrina. Shoreline Park has seen 30% of its total parcels change their structural footprints from 2007 – 2012 …

Situation Analysis Of Somalia’S 2011 Famine, Ahmed Mohamed Askar

Master of Public Health Program Student Publications

This CE examined the contributing factors of famine in Somalia and developed a situation analysis of Somalia’s 2011 famine. The situational analysis was developed using health and famine indicators. Data from geographic information system (GIS) was also used to supplement analysis to look for trends and patterns of the famine. I predicted that conflict was the leading factor in Somalia’s 2011 famine. I concluded that conflict exacerbated the famine situation in the south of Somalia but in the north (Somaliland) famine was due to climate and lack of permanent rivers and water sources.

Mapping Xenophobic Violence In South Africa: Modeling Spatial Relationships Between Group Grievances And Opportunities To Measure The Propensity For Xenophobic Violence, Eric Holder

Graduate Theses and Dissertations

Xenophobia can be defined as the hatred or fear of foreigners or strangers or of their politics or culture (Ngwane et al., 2008). This sentiment reached its tipping point in urban areas across the Republic of South Africa in May 2008 when mass, widespread and systematic attacks against African non-nationals took place across the country. Although previous research agrees on who played the various roles during this crisis event (Everatt, 2010), little research has been carried out to create a predictive model to assess where future violence could occur based on a set of conflict indicators. The purpose of this …

Agriculture, Influence, And Instability Under The Ancien Régime: 1708-1768, Adam J. Polk

Masters Theses

The French Revolution has been studied from myriad perspectives. The majority of scholarship focuses on the political and urban chaos of the times. Agricultural conditions and the influence of onerous taxation and stagnant agricultural options are given only a cursory examination in most research. This thesis aims to investigate the relationship between agronomic and environmental conditions and the eruption of violence in urban centers during the French Revolution and the years leading up to it (1708-1768). This period prior to the French Revolution serves as a template to investigate the nature of the rural-agricultural influences, with a particular focus paid …

Assessing The Impacts Of Dams On Nutrient And Sediment Loading In The Kalamazoo River Using The Soil And Water Assessment Tool (Swat), Daniel Henry Serfas

Masters Theses

The Soil and Water Assessment Tool (SWAT) was applied to the Kalamazoo River Watershed in order to evaluate the impacts that several dams within a superfund site "Area of Concern" have on the sediment, nutrients, and streamflow of the system. It was hypothesized that the SWAT model could be used to recreate the watershed in hopes of estimating the amounts of nitrogen, phosphorus, and sediment that would result from the removal of the dams. The model would then be used to evaluate dam removal scenarios to come up with a best management practice (BMP).

The model was calibrated, however, during …

Inter-Species Interactions: Effects Of Spatial Proximity Of Breeding Burrowing Owls (Athene Cunicularia) And Mountain Plovers (Charadrius Montanus) On Mountain Plover Nest Success, Lindsey Messinger

Geography and the Environment: Graduate Student Capstones

Predator-prey interactions are complex and direct interactions between predator-prey pairs are difficult to distinguish due to direct and indirect effects of additional predator-prey interactions. While most studies evaluating the impact of predators on prey concentrate on consumption (mortality of prey caused by a predator), there are a variety of interactions that take place between predators and prey that may not result in mortality. These in direct impacts of predation have been found to influence micro- and macro- habitat use, time allocation patterns, species distribution, population growth, and species interactions and can be just as strong or stronger than consumptive effects.

Mapping Sustainability: City Of Fife Parks And Recreation, Tonya Elliott

Geography and the Environment: Graduate Student Capstones

Sustainability is based on a simple principle: Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment. Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permits fulfilling the social, economic, and other requirements of present and future.

Mapping The Evolution Of Racially Mixed And Segregated Neighborhoods In Chicago, Jonathan Chipman, Richard Wright, Mark Ellis, Steven R. R. Holloway

Dartmouth Scholarship

The Chicago metropolitan region consists of a spatially complex mosaic of neighborhoods, in which measures of racial and ethnic composition vary dramatically. Understanding these patterns and their evolution has been hindered by ambiguities in the use of terms like ‘diverse’ or ‘segregated’, which are often posited as opposite ends of a one-dimensional scale. Using a new taxonomy of neighborhood composition, we have mapped the evolving patterns of Chicago's neighborhoods in 1990, 2000, and 2010, and tabulated census tracts that have undergone transitions or remained stable. Looking beyond the Chicago metropolitan area, we have developed an interactive atlas of similar maps …

Using Landscape Pattern Metrics To Characterize Ecoregions, Martha Isabel Posada Posada

School of Natural Resources: Dissertations, Theses, and Student Research

Ecological regions, or ecoregions, are areas that exhibit “relative homogeneity in ecosystems”. The principal objective of this research was to determine if and how landscape structure (quantified by landscape pattern metrics) may be related to ecoregions defined using Omernik’s approach to ecoregionalization. Nine key landscape pattern metrics (number or LULC classes and the proportion of each class, number of patches, mean patch size and area-weighted fractal dimension, perimeter-area fractal dimension, contagion, mean Euclidean nearest neighbor distance and interspersion and juxtaposition index) where used to asses landscape structure in a sample of 26 Omernik Level III ecoregions located in the central …

Climate Change And The Water Crisis In Israel, Lauren Deutsch

Natural Resources Management and Environmental Sciences

Israel’s water crisis is controlled by the availability and location of water resources that are affected by climate change and geopolitics in southwest Asia. Conflict between Israel and the Palestinian occupied territories in the Gaza Strip and the West Bank have put strains on the allocation of water recourses. The goal of this research was to model how much a change in climate will affect the amount of available freshwater in Israel. Intensive research taken from Israel and the occupied territories was carried out to understand how the amount of precipitation, rainfall, and the rate of evaporation is affected by …

Episodic Recruitment And Climate Analysis Of Ponderosa Pine On The Palmer Divide, Eastern Colorado, William Henry Brenton Jr.

Electronic Theses and Dissertations

Previous recruitment studies on populations of ponderosa pine (Pinus ponderosa P. & C. Lawson) in Colorado have been limited to the western mountains and the Front Range. In this research I used tree-ring data to reconstruct recruitment for ponderosa pine near the eastern limits of its distribution at two sites on the Palmer Divide, Eastern Colorado, to determine the relative climate sensitivity of the two sites, and the extent to which climate or other factors may have influenced recruitment at the sites. The results of the tree-ring analysis suggest that ponderosa pines in more the easterly site lower elevation …

Income Inequality In U.S. Metropolitan Areas: Which Areas Have The Greatest Inequality And Why?, C. Peterson Compton

Electronic Theses and Dissertations

In recent years, much focus has been placed on the high and growing level of income inequality in the United States. This composition begins to fill a void in the existing literature by examining specific urban areas that have particularly high levels of inequality and the characteristics that factor into inequality. In this paper, I construct a qualitative model for a particularly unequal metropolitan area. I then apply the model to a set of U.S. metros that are among the most unequal in the country and share a particular set of characteristics consistent with the model.

Contrast Based Band Selection For Optimized Weathered Oil Detection In Hyperspectral Images, Florian Levaux, Charles R. Bostater, Xavier Neyt

Ocean Engineering and Marine Sciences Faculty Publications

Hyperspectral imagery offers unique benefits for detection of land and water features due to the information contained in reflectance signatures such as the bi-directional reflectance distribution function or BRDF. The reflectance signature directly shows the relative absorption and backscattering features of targets. These features can be very useful in shoreline monitoring or surveillance applications, for example to detect weathered oil. In real-time detection applications, processing of hyperspectral data can be an important tool and Optimal band selection is thus important in real time applications in order to select the essential bands using the absorption and backscatter information. In the present …

The sensors include a multispectral digital frame camera system, a traditional photogrammetric camera, and a small custom hyperspectral imaging system with custom software. Ancillary sensors include include multiple differential GPS and inertial motion unit (IMU) …

Government Documents On Rare Earth Minerals, Bert Chapman

Libraries Faculty and Staff Presentations

Rare earth minerals contain unique chemical and physical properties such as lanthanum, are found in small concentrations, need extensive precise processes to separate, and are critical components of modern technologies such as laser guidance systems, personal electronics such as Blackberries, and satellites. The U.S. has some rare earth resources, but is heavily dependent on access to them from from Afghanistan, Bolivia, and China. Losing access to these resources would have significant economic, military, and political implications. This presentation will highlight government information resources on rare earth minerals from agencies such as the Department of Energy (DOE), Department of Defense (DOD), …

The Housing Preferences And Location Choices Of Second Generation South Asians Living In Ethnic Enclaves, Virpal Kataure, Margaret Walton-Roberts

Geography and Environmental Studies Faculty Publications

Canada has experienced the development of suburban ethnic enclaves by established immigrant diaspora groups surrounding major metropolitan centres. However, less is known regarding the housing and location preferences of their maturing offspring population, known as the second-generation. This paper seeks to explain the housing preferences and location choices of second-generation South Asians residing in Brampton's ethnic enclaves, a suburban city on the periphery of Toronto. This research draws on the home leaving process and integrates the theoretical perspectives of ethnic enclaves and the life cycle. A telephone survey conducted in Brampton's ethnic enclaves suggests a dominant preference of low-density, detached-style …

The Role Of Landscape Connectivity In Planning And Implementing Conservation And Restoration Priorities. Issues In Ecology, Doborah Rudnick, Sadie J. Ryan, Paul Beier, Samual A. Cushman, Fred Dieffenbach, Clinton Epps, Leah R. Gerber, Joel N. Hartter, Jeff S. Jenness, Julia Kintsch, Adina M. Merenlender, Ryan M. Perkl, Damian V. Perziosi, Stephen C. Trombulack

Geography

Landscape connectivity, the extent to which a landscape facilitates the movements of organisms and their genes, faces critical threats from both fragmentation and habitat loss. Many conservation efforts focus on protecting and enhancing connectivity to offset the impacts of habitat loss and fragmentation on biodiversity conservation, and to increase the resilience of reserve networks to potential threats associated with climate change. Loss of connectivity can reduce the size and quality of available habitat, impede and disrupt movement (including dispersal) to new habitats, and affect seasonal migration patterns. These changes can lead, in turn, to detrimental effects for populations and species, …
