In this study, we examine the relation between chief executive officers' (CEOs') general managerial skills and firms' risk‐taking behaviour. We find that generalist CEOs are associated with significantly higher firm risk, with the association decreasing significantly with CEO tenure. We propose the following managerial skills transformation explanation: the longer a CEO stays with a firm, the less general and more firm specific the CEO's skills and knowledge become; therefore, any effect of the CEO's general managerial skills only appears in the early years of tenure.

In this article, a new type of Cu–Co–P alloy with different atomic ratios of Co/P has been successfully synthesized, in which the Co 2 P particles have been formed. By means of the melt-spinning and phase extraction technologies, the pure Co 2 P particles with various morphologies could be obtained. It has been found that with the atomic ratio of Co/P changing from 1:2, 1:1, 3:2 to 2:1, the Co 2 P particles exhibit the morphologies of hollow hexagonal and quadrangular prisms, short rod-shape, fine and near-spheroidal particles, fibers and spheres, respectively. Besides of the stoichiometry of reactants Co/P, the non-equilibrium solidification caused by melt-spinning might be another reason for the morphological evolution of the Co 2 P phase. The synthesis of Co 2 P particles by the in-situ melt reaction provides an efficient, stable, controllable and green environment-friendly preparation method, in which the Cu–P alloy is supplied as the phosphorus resource. Meanwhile, this discovery provides new opportunities for the synthesis of transition metal phosphides. [ABSTRACT FROM AUTHOR]
