Appalachia has higher morbidity and mortality compared to the nation, and suffers greater socioeconomic disadvantages. This article investigates the relationship of coal mining to elevated mortality rates in Appalachia. Total mortality rates for the years 1999–2004 were investigated in a national county-level analysis that included coal mining as the primary independent variable. Counties in Ap...
Data mining is acquiring its own identity by refining concepts from other disciplines, developing generic algorithms, and entering new application areas. Engineering design and manufacturing have been affected by the data mining pursuit. This paper outlines areas of product and manufacturing system design that are particularly suitable for data-mining applications. One of the emerging areas is ...
OBJECTIVES We examined elevated mortality rates in Appalachian coal mining areas for 1979-2005, and estimated the corresponding value of statistical life (VSL) lost relative to the economic benefits of the coal mining industry. METHODS We compared age-adjusted mortality rates and socioeconomic conditions across four county groups: Appalachia with high levels of coal mining, Appalachia with lo...
This paper discusses a number of technologies, approaches, and research areas which have been identified as having critical and future promise in the field of data mining. Among the areas which are being developed, investigated, and applications identified for include hypertext and hypermedia data mining, ubiquitous data mining (UDM), phenomenal data mining, distributed and collective data mini...
The presence of heavy metals (metals with a density of over than 5 g cm-3) in the soil surfaces, are mainly due to industrial and mining activities, fuel combustion, etc. Although some of the metals are essential elements for plants, in the high concentrations have toxic effects on plants. Some of the plants those grown in mining areas are resistant to high concentration of heavy ...
