Socioeconomic Characteristics Of Cancer Mortality In The United States Of America: A Spatial Data Mining Approach, Srinivas Kumar Vinnakota Jan 2006

Socioeconomic Characteristics Of Cancer Mortality In The United States Of America: A Spatial Data Mining Approach, Srinivas Kumar Vinnakota

LSU Doctoral Dissertations

Cancer is the second leading cause of death in the United States of America. Though it is generally known that cancer is influenced by environment, its relation to socioeconomic conditions is still widely debated. This research analyzed the spatial distribution of cancer mortalities of breast, colorectal, lung, and prostate, and their associated socioeconomic characteristics using association rule mining technique. The mortality patterns were analyzed at the county and health service area levels that corresponded to the years between 1999 – 2002 and 1988 – 1992, respectively. Distinct socioeconomic characteristics of cancer mortality were revealed by the association rule mining technique. …


Spatial And Temporal Estimation Of Pumping And Recharge In Groundwater System Analysis, Sherly Hartono Jan 2005

Spatial And Temporal Estimation Of Pumping And Recharge In Groundwater System Analysis, Sherly Hartono

LSU Doctoral Dissertations

In many parts of the U.S., groundwater is used as the primary or secondary source of water for the public supply, agricultural, and industrial sectors. In southwestern Louisiana, a majority of the water demand is supplied by the Chicot aquifer. Numerical flow models are useful for managing and optimizing groundwater systems. However, many important model parameters are difficult to quantify, exhibit a certain degree of uncertainty, and may vary both spatially and temporally. Two of the most important and sensitive parameters for a regional groundwater model of the Chicot aquifer are pumping rates and recharge. The use of GIS-based methods …


Mapping The Other Truth In The Shintech Case: Emancipatory Mapping For Environmental Justice In South Louisiana, Charles Allen Flanagan Jan 2005

Mapping The Other Truth In The Shintech Case: Emancipatory Mapping For Environmental Justice In South Louisiana, Charles Allen Flanagan

LSU Doctoral Dissertations

This dissertation presents an alternative mapping approach which challenges the hegemony of abstract space and instrumental reason propagated by the U.S. Environmental Protection Agency (EPA) in its 1998 study of the Louisiana Department of Environmental Quality's (DEQ) permitting process. The "other truth" is presented through application of concepts from critical theory, critical geography, and the works of Henri Lefebvre to a specific environmental justice struggle in St. James Parish, Louisiana. In 1996 Shintech, Inc. proposed building a polyvinyl chloride facility in St. James Parish, Louisiana. The community, concerned about the considerable toxic burden already present in the area, formed a …


Biology And Ecology Of Leptographium Species And Their Vectos As Components Of Loblolly Pine Decline, Lori G. Eckhardt Jan 2003

Biology And Ecology Of Leptographium Species And Their Vectos As Components Of Loblolly Pine Decline, Lori G. Eckhardt

LSU Doctoral Dissertations

Loblolly pine (Pinus taeda L.) decline (LPD) has been present in upland sites of central Alabama since the 1960s. Symptoms of LPD (fine root deterioration, short chlorotic needles, sparse crowns, reduced radial growth) begin in the 30-40 yr age class, resulting in premature death at ages 35-50. Previously, declining loblolly was diagnosed as littleleaf disease (LLD); however, site conditions associated with LPD are different from LLD sites. Littleleaf disease only occurs on eroded, heavy clay soils and is secondarily associated with the fungus, Phytophthora cinnamomi. In contrast, LPD occurs on sandy, well-drained soils and is associated with Leptographium spp., as …
