from rhizome with slow establishment rates and current United Kingdom yields of 12--14 Mg ha^-1^, the breakeven payback time is 4 years for chipped harvesting and 6 years with bale harvesting. The worst case scenario of NPV in the United Kingdom is competitive with arable rotations. In continental climates with warmer summers, in this study exemplified by Potash in the Ukraine, yields reach 16 Mg ha^-1^ by the third year and breakeven payback time reduces to the third year including the costs of mulch film and seed-plug establishment. Further reductions in establishment costs are needed to increase farmer acceptance of the crop. Technological developments such as direct seeding, the use of film to speed establishment and the development of higher yielding, faster establishing genotypes are all part ofChange is inevitable--is it acceptable?
Three ophthalmologists with successful solo practices decided to incorporate into a group practice. As the years went by, the practice flourished, and new physicians and staff were added to the group. However, the group's cohesiveness began to dissipate soon after the corporation's tenth anniversary. The basis of compensation, as well as the viability of the group as an entity, began to be challenged. Change in the salary formula became inevitable, and with the change naturally came resistance from some of the group members. How did the group manage to survive?
