In this paper, the authors analyze the influence of a subsidiary's external environment, of its task and of its mode of ownership and its mode of market entry on the development of its role for the case of German subsidiaries in Central Europe. A subsidiary's role is defined as a three-dimensional construct, consisting of a subsidiary's tasks, its value chain activities and their respective geographical scope. Surveying 99 subsidiaries of German multinational Corporations (MNCs) located in the Czech Republic, Hungary, and Poland, the authors find that mode of entry and the subsidiary's task significantly influence the development of its role.

A numerical procedure for simulating the equilibrium shapes of precipitates in two-phase materials, such as Ni-base alloys, is presented. Assuming a periodic arrangement of precipitates, a unit cell is analyzed to take particle interaction in 3D into account. Using the concept of generalized driving forces as the source of morphological evolution, a necessary condition for an equilibrium shape is derived. In the derivation of the driving force, elastic strain energy arising from the elastic misfit of the two phases and interface energy is considered. Both phases are assumed to be linear elastic but anisotropic and different from each other. The periodic cell problem is numerically solved by the Boundary Element Method. Numerical simulation for material parameters which mimic Ni-base alloys shows the influence of particle size, stiffness ratio of the two phases, volume fraction and external load on the resulting equilibrium shapes.
