From kinetic theory to dissipative fluid dynamics
We present the results of deriving the Israel-Stewart equations of
relativistic dissipative fluid dynamics from kinetic theory via Grad's
14-moment expansion. Working consistently to second order in the Knudsen
number, these equations contain several new terms which are absent in previous
treatments.Comment: 7 pages, proceedings of the Erice School on Nuclear Physics "Heavy

Polarization probes of vorticity in heavy ion collisions
We discuss the information that can be deduced from a measurement of particle
(hyperon or vector meson) polarization in ultrarelativistic nuclear collisions.
We describe the sensitivity of polarization to initial conditions, hydrodynamic
evolution and mean free path, and find that the polarization observable is
sensitive to all details and stages of the system's evolution. We suggest that
an experimental investigation covering production plane and reaction plane
polarizations, as well as the polarization of jet-associated particles in the
plane defined by the jet and particle direction, can help in disentangling the
factors contributing to this observable. Scans of polarization in energy and
rapidity might also point to a change in the system's properties.Comment: In press, Phys.Rev.C. One new figure, text streamlined and edited,

Relativistic Viscous Hydrodynamics for Multi-Component Systems with Multiple Conserved Currents
We would like to formulate relativistic dissipative hydrodynamics for
multi-component systems with multiple conserved currents. This is important for
analyses of the hot matter created in relativistic heavy ion collisions because
particle creations and annihilations of various particle species are frequently
taking place there. We show that consistent formulation in such systems
involves many non-trivialities, and derive constitutive equations that satisfy
Onsager reciprocal relations and describe the systems without ambiguity.Comment: 4 pages, no figures - To appear in the conference proceedings for Hot

Late Planting Decisions with Crop Insurance: Decision Guidelines for Michigan Farmers in Spring 2011
Michigan has had unusually wet planting conditions in 2011, leading to substantial acreage that has not been planted at this late date. Farmers who purchased crop insurance have many options available to them. This paper addresses the major crop insurance decisions that farmers will face during the next 30 days.crop insurance, prevented planting, risk management, farm management, corn returns, soybean returns, Agricultural and Food Policy, Crop Production/Industries, Farm Management, Risk and Uncertainty,
