Год издания: 0000
This book furthers readers’ understanding of the amazing features of six-membered transition states in stereoselective organic reactions. Comprehensive and logically organized, it covers reactions classified in four categories: [3,3]-sigmatropic rearrangements, aldol reactions, metal allylation reactions, and stereoselective reductions. There is a thorough discussion of each reaction category, along with computational studies that support a proposal of a six-membered state. The book assists professors, researchers, and students in proposing reasonable transition states for the description of newly discovered stereoselective reactions.
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.
