Privatisation and sustainable competitive advantage in the emerging economies of Central Europe

Extant research on the impact of privatization in the Central Europe (CE) region has focused on improvements in efficiency and the nature of cost-based advantages. This study argues that the development of a vibrant privatized sector requires attention to the broader resource configurations of domestic enterprises. Empirical research was conducted on a large sample of firms in Poland, Hungary and Slovenia. Foreign investment was found to significantly impact on resource accumulation with implications for the development of strategic capabilities and competitive advantage. Foreign direct investment is an effective vehicle for the transfer of financial resources, reputation and new brands but not organizational capabilities. In terms of practice, this study demonstrates the important role of outside investment in the development of a firm's resource base (Frydman et al. 1999). Companies can gain a competitive advantage in their domestic markets through gaining access to the resources of foreign investors.

Power-controlled phase-matching and instability of CW propagation in multicore optical fibers with a central core

We present modulation instability analysis including azimuthal perturbations of steady-state continuous wave (CW) propagation in multicore-fiber configurations with a central core. In systems with a central core, a steady CW evolution regime requires power-controlled phase matching, which offers interesting spatial-division applications. Our results have general applicability and are relevant to a range of physical and engineering systems, including high-power fiber lasers, optical transmission in multicore fiber, and systems of coupled nonlinear waveguides. © 2013 Optical Society of America.
