Urbanization And Land Surface Temperature In Pinellas County, Florida, Bruce Coffyn Mitchell

USF Tampa Graduate Theses and Dissertations

Since the early 1800's, many studies have recognized increased heat in urban areas, known as the urban heat island (UHI) effect, as one of the results of human modification to the natural landscape. UHI is related to differences in land surface temperature (LST) between rural areas and urban areas where factors of the built environment such as the thermodynamic capacities of materials, structural geometry, and heat generating activities cause increased storage and re-radiation of heat to the atmosphere. This thesis examines the correlation between factors of urbanization and differences in land surface temperature (LST) in the subtropical climate of Pinellas …

Seeing The Forest Of Information For The Trees Of Papers: An Information Literacy Case Study In A Geography/Geology Class, Linda Blake, Tim Warner

Faculty & Staff Scholarship

After receiving a mini-grant for developing integrated information literacy programs, a Geography/Geology Department faculty member worked with the Science Librarian to embed information literacy in a cross-listed geology and geography course, Geog/Geol 455, Introduction to Remote Sensing. Planning for the revisions to the class started with identification of five key literacy standards for the discipline of remote sensing. Each standard was addressed through a combination of teaching, assignments and measurements. From this planning exercise, two lectures and two laboratory exercises on information literacy were developed. Student response to the information literacy material, as measured through pre- and post-course surveys, was …

Does Terrestrial Drought Explain Global Co 2 Flux Anomalies Induced By El Niño?, C. R. Schwalm, Christopher A. Williams, K. Schaefer, I. Baker, G. J. Collatz, C. Rödenbeck

Geography

The El Niño Southern Oscillation is the dominant year-to-year mode of global climate variability. El Niño effects on terrestrial carbon cycling are mediated by associated climate anomalies, primarily drought, influencing fire emissions and biotic net ecosystem exchange (NEE). Here we evaluate whether El Niño produces a consistent response from the global carbon cycle. We apply a novel bottom-up approach to estimating global NEE anomalies based on FLUXNET data using land cover maps and weather reanalysis. We analyze 13 years (1997-2009) of globally gridded observational NEE anomalies derived from eddy covariance flux data, remotely-sensed fire emissions at the monthly time step, …

Utilizing Temporally Invariant Calibration Sites To Classify Multiple Dates And Types Of Satellite Imagery, Joe Fortier, John Rogan, Curtis E. Woodcock, Daniel Miller Runfola

Geography

Mapping past time periods (retrospective mapping) using remotely sensed data is hindered by a lack of coincident calibration and validation information. The identification of features of same ground cover invariant across time and their use as calibration and validation data addresses this challenge by: (a) streamlining the process of image calibration for multiple dates, and (b) allowing each image to generate its own spectral signature. This study investigates the use of temporally invariant calibration and validation data to map land-cover in Massachusetts, employing five satellite images collected from five separate dates and different sensors. The results indicate that this technique …

Death To Kappa: Birth Of Quantity Disagreement And Allocation Disagreement For Accuracy Assessment, Robert Gilmore Pontius, Marco Millones

Geography

The family of Kappa indices of agreement claim to compare a map's observed classification accuracy relative to the expected accuracy of baseline maps that can have two types of randomness: (1) random distribution of the quantity of each category and (2) random spatial allocation of the categories. Use of the Kappa indices has become part of the culture in remote sensing and other fields. This article exam- ines five different Kappa indices, some of which were derived by the first author in 2000. We expose the indices' properties mathematically and illustrate their limitations graphically, with emphasis on Kappa's use of …

Placing Agency In Neoliberalism: Contested Citizenship In Spaces Of Migrant Organizing, Joseph Rasmussen

Geography Honors Projects

The presence of millions of immigrants without recognition from the federal government presents serious challenges to American democracy and its legitimacy. By analyzing immigration activism in Austin, Texas, this paper will consider how those excluded from formal citizenship seek full membership, or at least its associated rights and protections, and how institutions at a variety of scales responds to these efforts. This activism challenges prevalent notions of what citizenship means, expanding the lines of who deserve rights and protection, and constructs participatory citizenship at the city level rather than relying on the more passive, exclusionary model of federal politics.

Foreword, From Holy Places And Pilgrimages: Essays On India, Robert H. Stoddard

Geography Program: Faculty Publications

This collection of twelve articles continues a long and rich body of information about pilgrimages. Written materials in the form of pamphlets, guidebooks, manuals, itineraries, and treatises about pilgrimages date from antiquity (see, e.g. the discussion in this volume by Rana Singh about ancient epics, pp. 15-20). Travelling to places regarded by worshippers as having extraordinary spiritual power is a phenomenon permeating all religious traditions so it is logical that it appears in various literary forms.

Converting Vacant Lots Into Assets: Comparing National Community Garden Programs To Community Garden Projects In Columbus Ga, Amanda Rees, Joyce Wade

Columbus Community Geography Center

Many aspects of community life are negatively affected by vacant lots, to include neighborhood vitality, crime rates, and the viability of commercial districts. Vacant properties have been identified by both elected and appointed officials as offering significant challenges to neighborhood revitalization and improvement. A variety of techniques have been used to address these problems, one such approach is the development of community gardens. Converting vacant lots into community gardens can improve the quality of life among neighborhood residents, help build social capital, and improve neighboring property values. Beginning with a review of the impact of community gardens and their management, …

Evaluation Of Species Distribution Model Algorithms For Fine-Scale Container-Breeding Mosquito Risk Prediction, C. Khatchikian, Florencia Sangermano, D. Kendell, T. Livdahl

Geography

The present work evaluates the use of species distribution model (SDM) algorithms to classify high densities of small container-breeding Aedes mosquitoes (Diptera: Culicidae) on a fine scale in the Bermuda Islands. Weekly ovitrap data collected by the Department of Health, Bermuda for the years 2006 and 2007 were used for the models. The models evaluated included the algorithms Bioclim, Domain, GARP (genetic algorithm for rule-set prediction), logistic regression and MaxEnt (maximum entropy). Models were evaluated according to performance and robustness. The area under the receiver operating characteristic curve was used to evaluate each model's performance, and robustness was assessed according …

Market Intermediaries And Rural People In Bolivia's Forest Products Sector: Are Trusting Partnerships Possible?, James T. Murphy, Mary Lawhon

Geography

Decentralization in access to and control of Bolivia's forest resources, coupled with a rising global demand for tropical hardwoods, raises important questions about whether increased trade and community forest management (CFM) initiatives can enable forms of market integration that have more favourable outcomes for rural communities. This paper assesses the prospects for such a transition through an examination of the relationships linking wood product market intermediaries (brokers and buyers) to rural suppliers and forest communities in Bolivia. The analysis centres on whether trust - conceptualized as a power-laden sociospatial process driven by multiscalar factors - can evolve between buyers and …

Theorizing Practice In Economic Geography: Foundations, Challenges, And Possibilities, Andrew Jones, James T. Murphy

Geography

Over the last decade or so there has been an identifiable shift in the interests of many economic geographers towards a concern with practices: stabilized, routinized, or improvised social actions that constitute and reproduce economic space, and through and within which socioeconomic actors and communities embed knowledge, organize production activities, and interpret and derive meaning from the world. Although this shift has gained significant momentum its general theoretical significance remains somewhat unclear and the concept is vulnerable to criticisms that it is incoherent, too 'micro-scale' in emphasis, unable to provide valid links between everyday practices and higher-order phenomena (eg, institutions, …

Detection Of The Timing And Duration Of Snowmelt In The Hindu Kush-Himalaya Using Quikscat, 2000-2008, Prajjwal K. Panday, Karen E. Frey, Bardan Ghimire

Geography

The Hindu Kush-Himalayan (HKH) region holds the largest mass of ice in Central Asia and is highly vulnerable to global climate change, experiencing significant warming (0.21 ± 0.08 °C/decade) over the past few decades. Accurate monitoring of the timing and duration of snowmelt across the HKH region is important, as this region is expected to experience further warming in response to increased greenhouse gas forcing. Despite the many advantages and applications of satellite-derived radar scatterometer data shown for capturing ice and snow melt dynamics at high latitudes, similar comprehensive freeze/thaw detection studies at lower latitudes (including the HKH region) are …

Placing Reedy Creek Improvement District In Central Florida: A Case Study In Uneven Geographical Development, Kristine Bezdecny

USF Tampa Graduate Theses and Dissertations

This study is primarily about the theory of uneven geographical development. In an era when it is proclaimed that, through globalization, the world has become flat, the unevenness of economic and social development is often overlooked or suppressed. As the nexus between global and local processes, the urban space often becomes the site of conflict between those defining the hegemonic narrative of the space, from a global and flat perspective; and those experiencing heterogenous local narratives, whose uneven positions are reinforced by this hegemonic narrative.

This study explores the conditions of uneven geographical development in the urban space of central …

Up In The Air: The Global Economy, Economic Development, And Air Transportation In Tampa Bay, Florida, Clinton M. Elbow

USF Tampa Graduate Theses and Dissertations

A globally integrated economy is one of the most prominent features of globalization and how city stakeholders respond to the global economy varies from city to city. Connecting to the global economy is often portrayed to be necessary for the continued economic development of a metropolitan area. Large transportation infrastructures such as airports represent one of the most visible ways of connecting to the global economy. Decisions made by city stakeholders regarding airports in order to reposition their city in the global economy have profound consequences for its residents. This thesis aims to examine the role played by air transportation …

Palaeoclimatic Significance Of Perennial Ice Accumulations In Caves: An Example From Scarisoara Ice Cave, Romania, Aurel Persoiu Tiritu

USF Tampa Graduate Theses and Dissertations

Stable isotopes in ice cores drilled in the polar and high-mountain region have been used intensively to reconstruct past climatic changes and atmospheric dynamics. However, no similar studies have been conducted on perennial ice accumulations in caves due to a limited understanding of the links between the external and cave environments, and the way in which the climatic signal can be recorded by the cave ice.

In this thesis, we successfully designed and build a research methodology for the reconstruction of past climatic changes based on perennial ice accumulation in caves, using as example the Scarisoara Ice Cave, Romania. The …

Pce Groundwater Quality Assessment Of The University Of Northern Iowa Campus Area, Brian Gedlinske

Graduate Research Papers

Perchloroethylene (PCE), is a colorless, nonflammable, and relatively insoluble chlorinated solvent once widely used for dry cleaning and metal degreasing operations. Because of its past widespread use, poor solvent management practices, and environmental persistence, PCE is a common contaminant found in groundwater supplies. Potential health concerns include liver problems and increased cancer risk.

This research paper presents the findings of an effort to better characterize the spatial, temporal, and transport attributes of a PCE groundwater plume that exists within the Devonian aquifer underlying the University of Northern Iowa campus and the surrounding area in Cedar Falls, Iowa. Findings reveal the …

USF Tampa Graduate Theses and Dissertations

Pinellas County is located on a peninsula in Florida that experiences daily patterns of sea breeze associated rainfall mainly during the summer months of June through August. Previously, rainfall patterns, amounts and timing and severe weather in Pinellas County have not been examined considering dominant wind flow patterns, sea breeze circulations and other atmospheric variables. To improve forecasting of local mesoscale phenomena, this project examined the rainfall patterns, amounts and timing and severe weather occurrences that occur as a result of sea breezes and associated prevailing wind regimes within Pinellas County for the months of June, July and August for …

Values In Place: Intersecting Values In Rails To Trails Landscapes, Lisa Rainey Brownell

University of Kentucky Doctoral Dissertations

This dissertation is a study of the values and meanings people attach to places and why exploring those values is important in trails and historic preservation planning. From a foundation in critical humanistic geography and values based preservation literatures, the dissertation examines three rails to trails projects as case studies. Primary research questions include: how does a landscape become valued, devalued, and/or revalued through time? In what ways do different values of different people or groups intersect in rails to trails landscapes and how do they shape the landscape? How do historic values intersect with economic, social, political, and other …
