摘要: 已有研究主要关注授权型领导的正面影响,然而,新近的研究表明授权型领导可能也会引发潜在的负面效应。针对此问题,首先界定了授权型领导的概念及其核心特征。其次,基于双重任务加工效应、角色理论和内隐领导理论,阐释了授权型领导负面效应的理论机制,并进一步分析和总结了授权型领导的有效性在何种条件下能够实现。最后,提出了授权型领导负面效应未来研究方向的建议。

摘要: The unified processing and research of multiple network models are implemented, and a new theoretical breakthrough is made, which sets up two new theorems on evaluating the exact electrical characteristics (potential and resistance) of the complex m×n resistor networks by the Recursion-Transform method with potential parameters (RT-V), applies to a variety of different types of lattice structure with arbitrary boundaries such as the nonregular m×n rectangular networks and the nonregular m×n cylindrical networks. Our research gives the analytical solutions of electrical characteristics of the complex networks (finite, semi-infinite and infinite), which has not been solved before. As applications of the theorems, a series of analytical solutions of potential and resistance of the complex resistor networks are discovered. In particular, three novel mathematical propositions are discovered when comparing the resistance in two resistor networks, and many interesting trigonometric identities are discovered as well.
