MODELING NITRATE CONCENTRATION IN GROUND WATER USING REGRESSION AND NEURAL NETWORKS

Nitrate concentration in ground water is a major problem in specific agricultural areas. Using regression and neural networks, this study models nitrate concentration in ground water as a function of iron concentration in ground water, season and distance of the well from a poultry house. Results from both techniques are comparable and show that the distance of the well from a poultry house has a significant effect on nitrate concentration in groundwater.Environmental Economics and Policy, Livestock Production/Industries,

To determine if a relationship existed, teachers and principals at participating middle schools took the School Culture Survey (SCS). One conclusion of this study was that the school culture of the four participating West Virginia middle schools as perceived by teachers and principals was primarily about the presence of Unity of Purpose. Additionally, as a total group teachers and principals demonstrated a high level of agreement in their perceptions of each the six factors of school culture being present. There were also similarities in the perceptions between teachers and principals when separated in groups regarding each of the six factors of school culture measured. Finally, there was suggestive evidence that reading achievement in the special education subgroup may be related to a school culture that is perceived to contain each of the six factors measured
