Past research suggests that spiritual leadership plays a pivotal role in enhancing employee job performance, yet we have little understanding of how and when spiritual leadership enhances employee job performance. The present study explores how and when spiritual leadership promotes job performance by examining relational energy as a mediator and leader integrity and relational energy differentiation as boundary conditions. We tested the theoretical model with data gathered across three phases over 12 months from 497 employees and their supervisors in 108 (...) groups. Results showed that the positive relationship between spiritual leadership and job performance was mediated by relational energy. Moreover, we found that leader integrity amplified the mediated relationship between spiritual leadership and employee job performance via relational energy. In contrast, relational energy differentiation weakened this mediated relationship. (shrink)

The oscillations on output power and distortion of the inverter currents will occur in the case of unbalanced grid voltage faults. Constant output power and good current quality cannot be achieved simultaneously. Aiming at these problems, a coordinate control strategy for suppressing power fluctuations and current harmonics is proposed by analyzing instantaneous power control and current balance control. The proposed control is achieved by adjusting the weight coefficient of current reference values to change the current harmonic contents based on proportional (...) complex integral controller and proportional multiple complex integral controller. The control strategy with a simple control structure neither needs to detect harmonic components of the inverter currents, nor needs to separate the positive and negative components of voltage and current, which is easy to be realized. The feasibility and effectiveness of the proposed control are verified by the comparison and analysis of simulation. (shrink)

In this study, we examine the association between the ownership structure of Chinese listed firms and their audit choices among the Big 4, Second-tier, and Other firms between 2007 and 2012. The market share of the Big 4 firms in China was relatively low, while that of the Second-tier firms increasing during the sample period. Although there is little evidence to indicate that the audit quality of the Second-tier firms is not comparable to that of the Big 4 firms in (...) China, we find that large shareholders and boards of directors do not perceive the financial reporting credibility associated with the Second-tier firms to be the same as that of the Big 4 firms. We further find that the largest shareholders of Chinese listed firms prefer low-quality auditors when they have a low level of ownership but prefer high-quality auditors when they have a high level of ownership. The empirical evidence presented in this study should be of interest to regulators and academics. (shrink)

The terminology tianxia has both historical evolution and cultural and philosophical connotations. This concept not only denotes a geographical and spatial meaning, but also implies the moral construct of metaphysics. A systematic study of its historical and cultural repercussions can show that the evolution of the meaning "tianxia" not only embodies the cosmological construction, moral belief and self-identity of the Chinese nation, but also manifests the historical processes of modern China evolving from "tianxia" to a modern nation-state. Meanwhile, the deconstruction (...) of the tianxia cosmology has shattered the old Chinese concept of a single united tianxia, or the whole world under one Heaven. Also, "Confucian China" has been increasingly losing its vitality and strong hold on the people, while the concept of nation-state has gained its way into people's consciousness, which has added more diversity and open-mindedness to the concept of tianxia.
