Optimal Coverage Level Choice with Individual and Area Plans of Insurance

We theoretically examine a farmer’s coverage demand with area and individual insurance plans as either separate or integrated options. The individual and area losses are assumed to be imperfectly and positively correlated. With actuarially fair rates, the farmer will fully insure with the individual plan and demand no area insurance regardless of the plans being separate or integrated. Under separate plans, free area insurance and the fair rate for individual insurance, area insurance replaces a portion of individual insurance demand. Under integrated plans, free area insurance, and the fair rate for individual insurance, the farmer over-insures using both area and individual plans.Agricultural risk, area plans of insurance, crop insurance, Agribusiness, Agricultural and Food Policy, Agricultural Finance, Crop Production/Industries, Demand and Price Analysis, Farm Management, Research Methods/ Statistical Methods, Risk and Uncertainty, D81, G22, Q12, Q18,

The data mining: An analysis of 20 eclipsing binary light-curves observed by the INTEGRAL/OMC

Twenty eclipsing binaries were selected for an analysis from a huge database of observations made by the INTEGRAL/OMC camera. The photometric data were processed and analyzed, resulting in a first light-curve study of these neglected eclipsing binaries. Most of the selected systems are the detached ones. The system ET Vel was discovered to be an eccentric one. Due to missing spectroscopic study of these stars, further detailed analyses are still needed.Comment: 4 pages, published in 2009 New Astronomy 14, 12

Mott metal-insulator transition on compressible lattices

The critical properties of the finite temperature Mott endpoint are drastically altered by a coupling to crystal elasticity, i.e., whenever it is amenable to pressure tuning. Similar as for critical piezoelectric ferroelectrics, the Ising criticality of the electronic system is preempted by an isostructural instability, and long-range shear forces suppress microscopic fluctuations. As a result, the endpoint is governed by Landau criticality. Its hallmark is thus a breakdown of Hooke's law of elasticity with a non-linear strain-stress relation characterized by a mean-field exponent. Based on a quantitative estimate, we predict critical elasticity to dominate the temperature range DeltaT/Tc ~ 8% close to the Mott endpoint of kappa-(BEDT-TTF)2X.Comment: 4 pages, 6 figure

The data mining III: An analysis of 21 eclipsing binary light-curves observed by the INTEGRAL/OMC

Twenty-one eclipsing binaries were selected for an analysis from a huge database of observations made by the INTEGRAL/OMC camera. The photometric data were processed and analyzed, resulting in a first light-curve study of these neglected eclipsing binaries. In several systems from this sample even their orbital periods have been confirmed or modified. Thirty-two new minima times of these binaries have been derived.Comment: 8 pages, 2 figures, published in 2011NewA...16..157

A PRODUCER-LEVEL CROSS-HEDGE FOR ROUGH RICE USING WHEAT FUTURES

This study explores the potential of routine preharvest cross-hedging of rough rice using wheat futures contract prices. A numerical simulation approach combined with risk efficiency analysis evaluates a wide rage of cross-hedging alternatives. Results establish that farm-level cross-hedging can be considered a viable marketing alternative.Marketing,
