Perspectives in Supramolecular Chemistry will relate recent developments and new exciting approaches in supramolecular chemistry. In supramolecular chemistry, our aim is to understand molecular chemistry beyond the covalent bond – the series will concentrate on goal-orientated supramolecular chemistry. Perspectives in Supramolecular Chemistry will reflect research which develops supramolecular structures with specific new properties, such as recognition, transport and simulation of biosystems or new materials. The series will cover all areas from theoretical and modelling aspects through organic and inorganic chemistry and biochemistry to materials, solid-state and polymer sciences reflecting the many and varied applications of supramolecular structures in modern chemistry. Transition Metals in Supramolecular Chemistry Edited by Jean-Pierre Sauvage, Universite Louis Pasteur, Strasbourg, France The chemistry of weak forces and non-covalent interactions as pioneered by Pedersen, Lehn and Cram is considered to be the origin of modern supramolecular chemistry. 30 years ago transition metals and their complexes were not regarded as important to this science. Transition Metals in Supramolecular Chemistry clearly demonstrates that today, transition metal complexes are routinely used to build large multicomponent architectures which display new and exciting applications including molecular switches, liquid crystals, and molecular magnets.

Social Capital and Strategy Effectiveness: An Empirical Study of Entrepreneurial Ventures in a Transition Economy
Автор: I. Manev
Год издания:
Although new ventures’ competitive positioning and their founders’ social networks are both recognized as important in the context of transition economies, not much is known about their multiplicative effect on performance. We build on the strategic management literature and social network theory to develop theoretical predictions about the role of competitive strategies and social capital for entrepreneurial performance. These are tested with survey data from Bulgaria. We find that both the venture’s competitive strategic positioning and the founder’s networking positively influence performance. The hypothesized moderating effect of networking for the relationship between differentiation strategy and performance received only tentative support. Contrary to expectations, we find a negative moderating effect of networking for the relationship of cost leadership with performance. These results suggest that the entrepreneur’s network plays a role in shaping how strategies influence performance by possibly upholding differentiation and deemphasizing cost leadership strategy. Implications for managerial practice and public policy are discussed.
The Transition of Juan Romero

The story involves a mine that uncovers a very deep chasm, too deep for any sounding lines to hit bottom. The night after the discovery of the abyss the narrator and one of the mine's workers, Juan Romero, venture inside the mine, drawn against their will by a mysterious rhythmical throbbing in the ground.
