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
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, …
Death To Kappa: Birth Of Quantity Disagreement And Allocation Disagreement For Accuracy Assessment, Robert Gilmore Pontius, Marco Millones
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 …
Market Intermediaries And Rural People In Bolivia's Forest Products Sector: Are Trusting Partnerships Possible?, James T. Murphy, Mary Lawhon
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 …
The Geographic Profiling Of Poverty And Accessibility: The Case Of Two Provinces In The Philippines, Alexis M. Fillone, Nicanor Roxas Jr., Cristela G. Dakila
The Geographic Profiling Of Poverty And Accessibility: The Case Of Two Provinces In The Philippines, Alexis M. Fillone, Nicanor Roxas Jr., Cristela G. Dakila
DLSU Business & Economics Review
This study attempts to relate the poverty problem in the Philippines using spatial accessibility measures. Spatial accessibility is the ease with which one could avail of the social services and economic opportunities laid in geographic space to the individual. Using the provinces of Eastern Samar and Siquijor Island as case studies, a Social Composite Index (SCI) value for the household was derived from the 13+1 CBMS core indicators of poverty, which represents the unmet needs of the household and which was then aggregated at the barangay level. The spatial accessibility values were estimated by measuring how each barangay, specifically households, …
Sacred Stones For Sacred Structures: An Examination Of Patterns In The Temples And Twin Complexes At Tikal And Palenque, Meredith Mae Hild
Sacred Stones For Sacred Structures: An Examination Of Patterns In The Temples And Twin Complexes At Tikal And Palenque, Meredith Mae Hild
Honors Program Theses
Extensive work in uncovering and reconstructing Classic Maya temples has been completed while the importance of Maya studies has increased during the past centuries. Little has been done, however, in the interpretation of certain Maya structures within the context of Maya thought. That context includes an understanding of the Maya interpretation of their place within the cosmos, an aspect of Maya culture that dictated every individual's daily actions. Researchers have tended to focus on architectural analyses that describe the dimensions and building materials of temples and other monumental structures. This leads to interpretations that are lacking in cultural significance. While …

Web-Based Spatial Decision Support System And Watershed Management With A Case Study, Yanli Zhang, Matthew W. Mcbroom, J. Degroote, R. L. Kauten, P. K. Barten
Faculty Publications
In order to maintain a proper balance between development pressure and water resources protection, and also to improve public participation, efficient tools and techniques for soil and water conservation projects are needed. This paper describes the development and application of a web-based watershed management spatial decision support system, WebWMPI. The WebWMPI uses the Watershed Management Priority Indices (WMPI) approach which is a prioritizing method for watershed management planning and it integrates land use/cover, hydrological data, soils, slope, roads, and other spatial data. The land is divided into three categories: Conservation Priority Index (CPI) land, Restoration Priority Index (RPI) land, and …
The Spatial Distribution Of Solar Radiation Under A Melting Arctic Sea Ice Cover, Karen E. Frey, Donald K. Perovich, Bonnie Light
The Spatial Distribution Of Solar Radiation Under A Melting Arctic Sea Ice Cover, Karen E. Frey, Donald K. Perovich, Bonnie Light
Geography
The sea ice cover of the Chukchi and Beaufort Seas is currently undergoing a fundamental shift from multiyear ice to first-year ice. Field observations of sea ice physical and optical properties were collected in this region during June-July 2010, revealing unexpectedly complex spatial distributions of solar radiation under the melt-season ice cover. Based on our optical measurements of first-year ice, we found the under-ice light field in the upper ocean to be spatially heterogeneous and dependent on wavelength, ice thickness, and the areal and geometric distribution of melt ponded and bare ice surfaces. Much of the observed complexity in radiation …
Spatial And Interannual Variability Of Dissolved Organic Matter In The Kolyma River, East Siberia, Observed Using Satellite Imagery, Claire G. Griffin, Karen E. Frey, John Rogan, Robert M. Holmes
Spatial And Interannual Variability Of Dissolved Organic Matter In The Kolyma River, East Siberia, Observed Using Satellite Imagery, Claire G. Griffin, Karen E. Frey, John Rogan, Robert M. Holmes
Geography
The Kolyma River basin in northeastern Siberia, the sixth largest river basin draining to the Arctic Ocean, contains vast reserves of carbon in Pleistocene-aged permafrost soils. Permafrost degradation, as a result of climate change, may cause shifts in riverine biogeochemistry as this old source of organic matter is exposed. Satellite remote sensing offers an opportunity to complement and extrapolate field sampling of dissolved organic matter in this expansive and remote region. We develop empirically based algorithms that estimate chromophoric dissolved organic matter (CDOM) and dissolved organic carbon (DOC) in the Kolyma River and its major tributaries in the vicinity of …
A Synthesis Of The Long-Term Paleoclimatic Evolution Of The Arctic, Matthew O'Regan, Christopher J. Williams, Karen E. Frey, Martin Jakobsson
A Synthesis Of The Long-Term Paleoclimatic Evolution Of The Arctic, Matthew O'Regan, Christopher J. Williams, Karen E. Frey, Martin Jakobsson
Geography
Since the Arctic Ocean began forming in the Early Cretaceous 112-140 million years ago, the Arctic region has undergone profound oceanographic and paleoclimatic changes. It has evolved from a warm epicontinental sea to its modern state as a cold isolated ocean with extensive perennial sea ice cover. Our understanding of the long-term paleoclimate evolution of the Arctic remains fragmentary but has advanced dramatically in the past decade through analysis of new marine and terrestrial records, supplemented by important insights from paleoclimate models. Improved understanding of how these observations fit into the long-term evolution of the global climate system requires additional …

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
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 …

The Legal And Political Foundations Of Kosovo's Independence, Mensur Deva
Dissertations and Theses
The case of Kosovo's independence raised concern regarding setting a precedence for other pro self-determination movements in the world. The critical question is if the Kosovo case actually sets a precedent for these movements or if it is a unique case due to its sui generis situation. This paper is an attempt to analyze the legality and the legitimate right of Kosovo to become an independent state. The study examines the phenomenon of the creation of new states in the world, looking at historical events such as decolonization and the dissolution of communist countries in Eastern Europe. In addition, I …

Converting Vacant Lots Into Assets: Comparing National Community Garden Programs To Community Garden Projects In Columbus Ga, Amanda Rees, Joyce Wade
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, …
Haitian Diaspora Impact On Haitian Socio-Political And Economic Development, Sharleen Rigueur
Haitian Diaspora Impact On Haitian Socio-Political And Economic Development, Sharleen Rigueur
Dissertations and Theses
"There is a new perspective developing within the international community on Diasporas and their potential to assist in the development process of their country of origin. The discussion began from the realization that transnational flows of remittances from sending countries (core) to receiving countries (periphery) increasingly surpass donor contributions to developing countries. The argument further discusses different socio-economic strategies to use when diasporic communities residing in developed countries (core) are assisting their homeland (periphery). This paper will look at the Haitian Diaspora in the United States and its active transnational link to Haiti. Since the days of post-Duvalierism, the Haitian …

Embracing The New Geography Of Health Care: A Novel Way To Cover Those Left Out Of Health Reform, Nathan Cortez
Embracing The New Geography Of Health Care: A Novel Way To Cover Those Left Out Of Health Reform, Nathan Cortez
Faculty Journal Articles and Book Chapters
Even after landmark health reform in 2010, our health care system will not achieve universal coverage. The Patient Protection and Affordable Care Act is expected to leave 23 million uninsured after a decade. And until several major provisions take effect in 2014, 50 million will remain uninsured. This Article argues that cross-border health insurance plans that utilize foreign medical providers are a surprisingly feasible alternative for the residually uninsured. Cross-border plans can be much less expensive than traditional, domestic-only plans. And they might appeal to immigrants and others that are neither eligible for public plans nor able to afford private …

The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of India, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski
The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of India, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski
Publications and Research
This paper examines the patterns of greenhouse gas (GHG) emissions from urban areas in India—a rapidly growing and urbanizing nation. It uses a new dataset, Emission Dataset for Global Atmospheric Research (EDGAR) to estimate the urban share of national GHG emissions. It presents a geographic picture of emission variation by urban form (urban population size, area size, density, and growth rate), and economic (GDP and GDP per capita), geographic (location of emissions released: 20, 40, and 80 km from urban areas), and biophysical (ecosystem and climate: cooling degree days) characteristics. Dependent variables include emissions of carbon dioxide (CO2), methane (CH4), …

The Paradoxical Effect Of Intercity Transportation And Communications Infrastructure On Urban Concentration: The Dispersion-Concentration Model, Alvaro Ballarin Cabrera
The Paradoxical Effect Of Intercity Transportation And Communications Infrastructure On Urban Concentration: The Dispersion-Concentration Model, Alvaro Ballarin Cabrera
Economics Honors Projects
This study examines the effect of intercity transportation and communications infrastructure on urban concentration on a sample of 84 countries between the years 1960 and 2010. By comparing the effects of interregional transportation and communications infrastructure on primacy and urbanization, I find that (1) such investments promote population dispersion amongst connected areas and (2) population concentration from unconnected locations into connected ones. Therefore, intercity transportation and communications infrastructure is only effective at reducing excessive concentration when the dispersion effect exceeds the concentration effect.
