A Tool For Estimating Best Management Practice Effectiveness In Arkansas, Katherine R. Merriman, Margaret Gitau, Indrajeet Chaubey

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Increased nutrient and sediment losses from expanding agricultural practices and urban development in Arkansas are important environmental concerns. Best Management Practices (BMPs) are being implemented to lessen the effects of these developments on existing water bodies. There is, however, insufficient scientific base as to the effectiveness of these practices. A number of studies have been conducted in recent years to determine BMP effectiveness. Data from these studies can only be reliably used for the individual site from which they were obtained. When considered collectively, these data comprise quantitative effectiveness over a wide range of conditions and can thus be used …

Medicaid Third-Party Liability And Claims For Restitution: Defining The Proper Role For The Tort System In Regulating The Food Industry, Coby Warren Logan Dec 2005

Medicaid Third-Party Liability And Claims For Restitution: Defining The Proper Role For The Tort System In Regulating The Food Industry, Coby Warren Logan

Journal of Food Law & Policy

This comment contends that tort liability can complement legislative and administrative government regulation of the food industry, providing sellers and manufacturers of food with an incentive to prevent consumers from over-consumption and becoming obese. Specifically, this comment supports the proposition that after government regulations are promulgated by Congress, claims should be allowed by state attorneys general to recoup Medicaid costs incurred in treating health conditions and illnesses caused by obesity.
