Ice-penetrating radar produces detailed images of the internal ice layers in a glacier. Because the layers form from each year's snowfall, the curving of the internal layers is a record of the climate conditions that the glacier experienced as it flowed throughout the millennia. The Hiawatha Glacier lies on top...
This dissertation re-examines the now standard perceptual model of hillslope
hydrological response to rainfall, which includes the growth of a saturated wedge at the soil-bedrock interface or impeding layer. It also challenges the notion of bedrock impermeability and the assumption that the pattern of subsurface stormflow is determined by the...
In this study overall financial development and the performance of commercial banks in Georgia during 1991-2000 is analyzed. Georgian banking system emerged from a scratch after the country gained its independence in 1991. Initial reform path turned out to be very arduous, full of failures and disappointments. After complete chaos...
The effects of fire on above-ground forest systems have been extensively studied. However, research on fire effects on belowground processes is lacking. While the soil microbiome is understood to be vital to conifer growth and regeneration, the complexity of soils means that research on the topic has largely been accomplished...
The effects of a school-based social-emotional and character development program, Positive Action, on the developmental trajectory of character development was evaluated using data from three randomized trials. Results come from 1) 4-years of data from elementary children in 20 Hawai`i schools, 2) 3-years of data from elementary children in 14...
Measurement is at the heart of any good research project. Although Classical test theory is the most widely used measurement theory, many alternative theories have emerged in the last hundred years. Rasch modeling is one such theory and by taking a different approach to measurement holds the possibility of enhancing...
Recent studies have suggested that the marine contribution of methane from shallow regions and melting marine-terminating glaciers may have been underestimated. Here we report on methane sources and potential sinks associated with methane seeps in Cumberland Bay, South Georgia's largest fjord system. The average organic carbon content in the upper...
The migrations of four generations of the Powledge family centering around Meriwether County, Georgia were described within the context of social and economic forces in the United States in 1820 to 1900. The family was representative of thousands of families that migrated westward. The migrations were found to correlate with...
