GSCE Faculty Publications
Land surface phenology is widely retrieved from satellite observations at regional and global scales, and its long-term record has been demonstrated to be a valuable tool for reconstructing past climate variations, monitoring the dynamics of terrestrial ecosystems in response to climate impacts, and predicting biological responses to future climate scenarios. This study detected global land surface phenology from the advanced very high resolution radiometer (AVHRR) and the Moderate Resolution Imaging Spectroradiometer (MODIS) data from 1982 to 2010. Based on daily enhanced vegetation index at a spatial resolution of 0.05 degrees, we simulated the seasonal vegetative trajectory for each individual pixel …

Validation Of Satellite Rainfall Products For Western Uganda., Jeremy E. Diem, Joel N. Hartter, Sadie J. Ryan, Michael W. Palace
Geography
Central equatorial Africa is deficient in long-term, ground-based measurements of rainfall; therefore, the aim of this study is to assess the accuracy of three high-resolution, satellite-based rainfall products in western Uganda for the 2001–10 period. The three products are African Rainfall Climatology, version 2 (ARC2); African Rainfall Estimation Algorithm, version 2 (RFE2); and 3B42 from the Tropical Rainfall Measuring Mission, version 7 (i.e., 3B42v7). Daily rainfall totals from six gauges were used to assess the accuracy of satellite-based rainfall estimates of rainfall days, daily rainfall totals, 10-day rainfall totals, monthly rainfall totals, and seasonal rainfall totals. The northern stations had …

Addressing Water Resource Issues In Barbados Through An Isotopic And Atmospheric Characterization Of Precipitation Variability, Veronica Hall
Masters Theses & Specialist Projects
Numerous studies have analyzed isotopic variation of meteoric and dripwater in karst environments for paleoclimate reconstructions or aquifer recharge capacity. What is poorly understood is how the isotopic signal of δ18O and δ2H is transferred through the hydrologic cycle based upon storm type, frequency, intensity, and teleconnection activity in the tropical karst areas. At Harrison’s Cave, Barbados, a Hobo Onset event data logger was attached to a tipping bucket rain gauge to count the tips and record the total rainfall every 10 minutes. In the cave a Hobo data logger was used to record relative humidity …

Impacts Of Carbonate Mineral Weathering On Hydrochemistry Of The Upper Green River Basin, Kentucky, Laura Leigh Osterhoudt
Masters Theses & Specialist Projects
Kentucky’s Upper Green River Basin has received significant attention due to the area’s high biodiversity and spectacular karst development. While carbonate bedrock is present throughout the watershed, it is more extensive and homogenous along the river between Greensburg and Munfordville than upstream from Greensburg where the geology is more heterogeneous. This research quantitatively evaluated how lithological differences between the two catchment areas impact hydrochemistry and inorganic carbon cycling. This first required correcting catchment boundaries on previous US Geological Survey Hydrologic Unit Maps to account for areas where the boundaries cross sinkhole plains. Basin boundaries using existing Kentucky Division of Water …

Land Cover Change And Its Impacts On A Flash Flood-Producing Rain Event In Eastern Kentucky, William N. Rodgers
Masters Theses & Specialist Projects
Eastern Kentucky is a 35-county region that is a part of the Cumberland Plateau of the Appalachian Mountains. With mountaintop removal and associated land cover change (LCC) (primarily deforestation), it is hypothesized that there would be changes in various atmospheric boundary layer parameters and precipitation. In this research, we have conducted sensitivity experiments of atmospheric response of a significant flash flood-producing rainfall event by modifying land cover and topography. These reflect recent LCC, including mountaintop removal (MTR). We have used the Weather Research and Forecasting (WRF) model for this purpose. The study found changes in amount, location, and timing of …

Geologic Factors Affecting Hydrocarbon Occurrence In Paleovalleys Of The Mississippian-Pennsylvanian Unconformity In The Illinois Basin, Jeremy Taylor London
Masters Theses & Specialist Projects
Paleovalleys associated with the Mississippian-Pennsylvanian unconformity have been identified as potential targets for hydrocarbon exploration in the Illinois Basin. Though there is little literature addressing the geologic factors controlling hydrocarbon accumulation in sub-Pennsylvanian paleovalleys basin-wide, much work has been done to identify the Mississippian-Pennsylvanian unconformity, characterize the Chesterian and basal Pennsylvanian lithology, map the sub-Pennsylvanian paleogeology and delineate the pre-Pennsylvanian paleovalleys in the Illinois Basin. This study uses Geographic Information Systems (GIS) to determine the geologic factors controlling the distribution of hydrocarbon-bearing sub-Pennsylvanian paleovalley fill in the Illinois Basin. A methodology was developed to identify densely-drilled areas without associated petroleum …

Masters Theses & Specialist Projects
The decision to live in a particular place, accept a job at a distant location, where to go shopping or purchase groceries, and many other similar decisions are all largely influenced by the availability of transportation. As such, it is important that everyone who requires transportation can have access. However, certain population segments, such as low income earners, are less likely to own cars due to the cost involved. There are others who may be impaired physically or have other difficulties that may prevent them from driving. Access to transportation is essential for people of all backgrounds and social statuses. …

"I Want To Be Brave": A Baseline Study On The Vulnerabilities Of Street-Working Boys In Sihanoukville, Cambodia, Jarrett Davis, Glenn Miles, M’Lop Tapang
Annual Interdisciplinary Conference on Human Trafficking: 6th (2014)
Focusing on street-working boys in Sihanoukville, this study partnered with social workers and child protection officers from M’lop Tapang (a key social service provider in Sihanoukville) to identify locations where young boys were known to be working along the beaches and within the town center. In recent years, Sihanoukville has become known as a rapidly developing commercial beach area, which has received increasing attention from foreign tourists, backpackers, and ex-patriots. Within this context, it has become a destination for migrant workers from surrounding provinces who have hopes of generating income through selling, begging, and other various means. The study conducted …

Urban Agriculture: An Environmental And Moral Imperative, Bridgit Hohlfeld
Geography and Planning
As we live in a society completely dependent on oil and its products, the contradictions within this self destructive system begin to unfold. Petroleum, its acquisition, and the products created with it, have been proven to cause unmanageable effects on a worldwide scale. As our natural resources become more finite, contributing to global and local inequities through widespread competition, the need for change is apparent. By introducing local farming initiatives, the creation, distribution, and usage of these products becomes obsolete through the elimination of demand and necessity. Sustainable urban agriculture is therefore presented as a tangible solution to the problem …

Geographic Variation Of Health Care Spending On Heart Failure In Metropolitan Areas, Kevin Mcmillan
Department of Geography: Dissertations, Theses, and Student Research
The costs of healthcare have long been a concern in the United States. It is well known that these costs vary geographically, but attempts to explain this variation have been met with limited and varied success. This is partly attributable to the fact that data available have restricted analyses to assessing the issue to using Medicare cost per beneficiary. In June, 2013, the Center for Medicare and Medicaid Services (CMS) released new Medicare data that detailed the charges and payments made to hospitals throughout the United States in 2011. In this thesis, this new dataset was used to examine costs …

An Examination Of Cultural Motives, Festival Motivator Attributes, Desired Experiences And Authenticity In Tourists To Oktoberfest In Helen, Georgia, Janet Marie Gunnels
All Theses
Helen, Georgia is nestled in a valley of the southern Blue Ridge Mountains along the Chattahoochee River in northeast Georgia. Originally a logging community serving as a stop for tourists to Anna Ruby Falls, Helen is now a faux-Bavarian town and the third largest tourist draw in the state. Research exists on 'theme towns' paying tribute to their cultural background by hosting seasonal events to boost tourism. There are also studies on residents of a town with an Oktoberfest, but little research exists concerning places using a not-native history to accomplish similar goals of producing cultural events that tourists see …

Troubled Waters: Georgia, Florida And Alabama's Conflict Over The Waters Of The Acf River Basin, Johnny King Alaziz Wong
USF Tampa Graduate Theses and Dissertations
Since 1989, the co-riparian States of Georgia, Florida and Alabama have been locked in an overt and institutionalized conflict to secure access to the waters of the Apalachicola-Chattahoochee-Flint (ACF) River Basin. In 1997, in an effort to end this interstate conflict which had earned the reputation as the longest water conflict in U.S. history, public officials at the federal and state scales agreed to suspend all pending litigation against one another and concurrently deployed a dispute resolution mechanism, known as `compact negotiations,' in the hope of equitably allocating the waters of the ACF Basin. Despite proclamations by public officials, exclaiming …

Impact Of Soil Moisture–Atmosphere Interactions On Surface Temperature Distribution, Alexis Berg, Benjamin R. Lintner, Kirsten L. Findell, Sergey Malyshev, Paul C. Loikith, Pierre Gentine
Geography Faculty Publications and Presentations
Understanding how different physical processes can shape the probability distribution function (PDF) of surface temperature, in particular the tails of the distribution, is essential for the attribution and projection of future extreme temperature events. In this study, the contribution of soil moisture–atmosphere interactions to surface temperature PDFs is investigated. Soil moisture represents a key variable in the coupling of the land and atmosphere, since it controls the partitioning of available energy between sensible and latent heat flux at the surface. Consequently, soil moisture variability driven by the atmosphere may feed back onto the near-surface climate—in particular, temperature. In this study, …

Rethinking Heterolocalism: The Case Of Place-Making Among Albanian-Americans, Merita Bushi
Geography Honors Projects
The theory of heterolocalism explores how immigrants connect to their new setting without clustering among co-ethnics. This research explores the role that Albanian-American organizations in Chicago and New York have in immigrant place-making and building a sense of community through semi-structured interviews and participant observation. The focus on institutions shifts the discourse from individual behaviors to networks. The Albanian case study is used to argue that segmented heterolocalism is more nuanced and thus describes the sociospatial behavior of immigrants in a way that resonates more closely with immigrants and incorporates their sense of community in a place.

The Social Implications Of Bicycle Infrastructure: What It Means To Bike In America's Best Cycling Cities, Erin Daly
Geography Honors Projects
The abundance of bicycle infrastructure appearing alongside controversial urban revitalization efforts in recent years has left many with distinct perceptions about people who ride bicycles and their role in society. The lifestyle associated with the most visible cyclist cohorts has furthered divisive perceptions and often times created resentment, as what was once a humble tool for mobility has become a symbol of an inaccessible cyclist “culture” often associated with gentrification. This paper aims to acknowledge existing research on how the bicycle has attained so many divisive connotations, while looking at methods to improve this reputation and increase accessibility to utilitarian …

The Lebanese and Lebanese-American community in the United States is known for both its entrepreneurship and its unusually long-lasting cultural memory. Though relatively small communities, the Lebanese and Lebanese-Americans have had a disproportionately large impact on the landscape of the Twin Cities. This paper examines how Christian Lebanese communities in Northeast Minneapolis and the West Side of Saint Paul have used placemaking as a means to retain their cultural heritage, form an original Lebanese-American identity, and alternatively resist and embrace assimilation. It also considers the fluidity of Lebanese-American identity, and how the gray areas of rigid American societal politics have …

Spreading The Char: The Importance Of Local Compatibility In The Diffusion Of Biochar Systems To The Smallholder Agriculture Community Context, Laura C. V. Munoz
Pomona Senior Theses
This thesis enters the context of smallholder agriculture communities in the developing world. It explores the potentials of biochar and what biochar systems could bring to the smallholder communities while simultaneously bringing environmental benefits. It then acknowledges the challenges of diffusion –the spreading of an unfamiliar innovation. It seeks to answer the question of what will make diffusion of biochar systems more successful in the smallholder context, fixating on the characteristic of compatibility as well as the role local community members can play in making a new biochar system more visible to the rest of the communities.

Human communities depend upon a myriad of ecosystem goods and services, which are produced by and depend on natural environmental processes occurring at multiple temporal and spatial scales. Land-use policy seldom recognizes the importance of these services or the environmental processes generating these services. This study examined the degree to which ecosystem services and supporting environmental processes are regulated at two United States municipal levels: city and county. Several ecosystem services but few environmental processes are regulated to some extent. We identified policy needs for environmentally sensitive karst features, aquifer recharge, groundwater quality, plant and animal populations, and flood mitigation. …
