Mathematical programming models are widely used in agricultural sector analysis. However, the lack of micro-level data, as well as computational requirements, necessitate the aggregation of individual producers into representative units when working at the sectoral level. This usually leads to...

This article presents a mathematical programming approach to determine a conservation strategy that maximizes preserved species' diversity under limited resource availability. Diversity is defined as the negative of total diversity loss given by the sum of genetic distances between extinct...

U.S. pork production and processing is consolidating in larger, more economically efficient units, and shifting from the Midwest into the Southeast. A regionalmodelof farm supply and processing demand shows that smaller Midwest operations can survive only if processing capacity remains...

A measure of divergence (NAD) between the distribution of individuals in a community and a target distribution is presented. When the latter is uniform, NAD measures evenness and exhibits a strong correlation with the widely used Shannon index. However, NAD offers the capability to incorporate...
