LYING ABOUT WHAT YOU KNOW OR ABOUT WHAT YOU DO?

We compare communication about private information to communication about actions in a one-shot 2-person public good game with private information. The informed player, who knows the exact return from contributing and whose contribution is unobserved, can send a message about the return or her contribution. Theoretically, messages can elicit the uninformed player's contribution, and allow the informed player to free-ride. The exact language used is not expected to matter. Experimentally, however, we find that free-ride depends on the language: the informed player free-rides less-and thereby lies less frequently-when she talks about her contribution than when she talks about the return. Further experimental evidence indicates that it is the promise component in messages about the contribution that leads to less free-ride and less lying. © 2013 by the European Economic Association

Analysis of stabilization operators in a Galerkin least-squares finite element discretization of the incompressible Navier-Stokes equations

In this paper the design and analysis of a dimensionally consistent stabilization operator for a time-discontinuous Galerkin least-squares finite element method for unsteady viscous flow problems governed by the incompressible Navier-Stokes equations, is discussed. The analysis results in a class of stabilization operators which satisfy essential conditions for the stability of the numerical discretization

Significance of pH-value for meat quality of broilers: Influence of breed lines

For determination of poultry quality shortly after slaughtering, physical criteria (pH-value, conductivity, colour, juice retention) are of importance. However, they are affected by breeding, transport, cooling and the storage period. PH-values of breast meat (genetically structured material) were recorded shortly after slaughtering (15 min p.m.) and differences between breeding line and gender were found (n=5109). The pH1-values ranged from 5.50 to 6.79. Male broilers showed significantly lower pH1-values than female ones (6.02:6.10). There were also significant differences concerning breeding line and gender. Meat quality (PSE, DFD) of broilers can be recorded quickly and accurately determining the pH1-value of breast meat. Threshold ranges to be considered are ≤ 5.8 (PSE), 5.9-6.2 (standard meat properties) and ≥ 6.3 (DFD). This classification is not to be compared to the deviation of pork
