Managing Multiple Sources of Competitive Advantage in a Complex Competitive Environment

The aim of this article is to review the literature on the topic of sustained and temporary competitive advantage creation, specifically in dynamic markets, and to propose further research possibilities. After having analyzed the main trends and scholars’ works on the subject, it was concluded that a firm which has been experiencing erosion of its core sources of economic rent generation, should have diversified its strategy portfolio in a search for new sources of competitive advantage, ones that could compensate for the decline of profits provoked by intensive competitive environments. This review concludes with the hypothesis that firms, who have decided to enter and manage multiple competitive environments, should have developed a multiple strategies framework approach. The management of this source of competitive advantage portfolio should have allowed persistence of a firm’s superior economic performance through the management of diverse temporary advantages lifecycle and through a resilient effect, where a very successful source of competitive advantage compensates the ones that have been eroded. Additionally, the review indicates that economies of emerging countries, such as the ones from the BRIC block, should present a more complex competitive environment due to their historical nature of cultural diversity, social contrasts and frequent economic disruption, and also because of recent institutional normalization that has turned the market into hypercompetition. Consequently, the study of complex competition should be appropriate in such environments

Formation of periodic crack structures in polydiacetylene single crystal thin films

The formation of a regular pattern of periodic cracked ridges on single crystal polydiacetylene films is described. Films thicker than a certain critical thickness are cracked while thinner ones are not. A model in the framework of linear elasticity theory is developed, which accounts for this transition as a function of the film thickness.Nous décrivons ici les conditions d'apparition d'un réseau de fractures périodiques dans des films monocristallins de polydiacétylène. Les films dont l'épaisseur est supérieure à une certaine épaisseur critique présentent ces fractures, tandis que les plus minces ne sont pas fracturés. Un modèle basé sur la théorie élastique linéaire rend compte de cette épaisseur critique
