We prove that the Chow motive of an anisotropic projective homogeneous variety of type F4 is isomorphic to the direct sum of twisted copies of a generalized Rost motive. In particular, we provide an explicit construction of a generalized Rost motive for a generically splitting variety for a symbol in K3 (k)/3. We also establish a motivic isomorphism between two anisotropic non-isomorphic projec...

In many European countries, a majority of employees are hired under very protective labor contracts that restrict the ability of the employer to dismiss them. In particular, employees can take to courts the firm’s layoff motive. Given the high costs specific to so-called economic motives and judges’ limited ability to process an ever growing flow of cases, in the last few years firms have been ...

to measure an unbiased farm-specific efficiency of individual dairy farmers, a shadow-price profit frontier adjusted for market distortion was applied to a sample of 860 iranian small intensive dairy farms surveyed in 2005-2006. this measure was then compared with that of unadjusted measure that assumes undistorted market. a multiple general linear model (glm) technique was applied to the data ...

Programming problems are defined by a constraint set and an objective function. The role of the constraint set is to limit the courses of action— the technical word is activities—to those that are feasible, and the role of the objective function is to give the preference relation on the activities. 1 The aim is to find a feasible activity that is preferred or indi¤erent to all other feasible ac...
