An Integrated Drought Index (Idi) Incorporating Physical And Social Aspects, Rebecca L. Lanier
An Integrated Drought Index (Idi) Incorporating Physical And Social Aspects, Rebecca L. Lanier
Master's Theses
The purpose of this research was to determine significant bio-physical (physical and environmental) and social variables that can be integrated into a drought index to predict areas susceptible to drought. Severe drought events are capable of causing millions of dollars in damage. The 1988 drought caused the United States approximately $40 billion in damage. Drought forecasting, modeling, and detection have, therefore, become imperative to understand the social, economic and environmental impacts of droughts, and also to explore how these impacts play a role in the occurrence of a drought. A number of drought indices widely used in the U.S. rely …
Human Impacts On Fire In De Soto National Forest, Mississippi, U.S.A., Charles Raymond White
Human Impacts On Fire In De Soto National Forest, Mississippi, U.S.A., Charles Raymond White
Master's Theses
Fire is a common occurrence in the longleaf pine (Pinus palustris) forests of the Southeast United States. Prescribed fire is used to manage these threatened ecosystems, but information regarding historical fire activity is unknown. My goals were to determine the historical fire regimes in De Soto National Forest (DSNF), southern Mississippi, and determine the influence of climate and land use history on fire activity at two study sites: Fern Gulley Ridge (FGR) and Death Scar Valley (DSV). The composite mean fire interval during the prescribed burning period (1980–2013) was 3.4 years. During settlements periods, fire intervals at FGR …
Application Of A New Tree-Ring Based Drought Reconstruction Method At Multiple Forest Sites Across Indiana, U.S.A., Kayla Mechelle Pendergrass
Application Of A New Tree-Ring Based Drought Reconstruction Method At Multiple Forest Sites Across Indiana, U.S.A., Kayla Mechelle Pendergrass
Master's Theses
This thesis research used techniques of dendrochronology to investigate the efficacy of using multiple co-occurring species (MCOS) in a climate reconstruction model compared to a single species (SS) in four old-growth forests in Indiana: Pioneer Mothers Memorial Forest (PM), Donaldson Woods (DW), Hoot Woods (HW), and Lilly Dickey Woods (LD). The objectives of this study were to [1] evaluate the climate response of all chronologies (n = 19; 7 species) to determine the most appropriate climate variable for reconstruction and [2] determine if the MCOS model outperforms the SS model at each individual study site. Model comparison was conducted …
High School Culture, Graduation Rates, And Dropout Rates, Philip L. Pearson
High School Culture, Graduation Rates, And Dropout Rates, Philip L. Pearson
Dissertations
High school graduation rates and dropout rates have been a source of concern for many years. A number of strategies have been studied that could improve graduation rates and reduce dropout rates. School culture has been touted as an area that affects student achievement. As the culture of schools improves, student achievement has been shown to improve. The research focus of this study was to determine if there is a relationship between high school culture in public high schools in Mississippi and the graduation and dropout rates. School culture was measured by the School Culture Survey (SCS). As scores on …
