THE IMPACT OF ALTERNATIVE PAYMENT ARRANGEMENTS ON THE PERFORMANCE OF FLORIDA SUGARCANE COOPERATIVES

Payment arrangements among members of a cooperative play a critical role in the performance of the cooperative. The impact of three payment systems is assessed for Florida sugarcane cooperatives through a bi-level programming model which incorporates both individual and collective behavior.Agricultural Finance,

Transverse transport in graphite

Graphite is a layered material showing a strong anisotropy. Among the unconventional properties reported by experiments, the electronic transport along the c-axis, which has direct implications in order to build graphitic devices, remains a controversial topic. We study the influence of inelastic scattering on the electron tunnelling between layers. In the presence of electron electron interactions, tunnelling processes are modified by inelastic scattering events.Comment: 9 pages, no figures Proceedings of the Graphene Conference, MPI PKS Dresden, September 200
