Ethical Leadership and Follower’s Work Attitude: The Role of Moral Identification

Drawing on moral self and social identity theory, this study investigated the mediating mechanism of moral identification in the relationship between ethical leadership and employee work attitudes: affective commitment and turnover intention. The sample for this study was drawn from telecom sector in Pakistan. Results for this sample showed that ethical leadership was positively associated with affective commitment, while negatively associated with turnover intentions. Furthermore, moral identification mediated the effects of ethical leadership on affective commitment and turnover intentions. This study discussed the theoretical and practical implications for study results.   Keywords: Ethical leadership, Moral Identification, Affective Commitment, Turnover Intention

Dynamics based Privacy Preservation in Decentralized Optimization

With decentralized optimization having increased applications in various domains ranging from machine learning, control, sensor networks, to robotics, its privacy is also receiving increased attention. Existing privacy-preserving approaches for decentralized optimization achieve privacy preservation by patching decentralized optimization with information-technology privacy mechanisms such as differential privacy or homomorphic encryption, which either sacrifices optimization accuracy or incurs heavy computation/communication overhead. We propose an inherently privacy-preserving decentralized optimization algorithm by exploiting the robustness of decentralized optimization to uncertainties in optimization dynamics. More specifically, we present a general decentralized optimization framework, based on which we show that privacy can be enabled in decentralized optimization by adding randomness in optimization parameters. We further show that the added randomness has no influence on the accuracy of optimization, and prove that our inherently privacy-preserving algorithm has $R$-linear convergence when the global objective function is smooth and strongly convex. We also rigorously prove that the proposed algorithm can avoid the gradient of a node from being inferable by other nodes. Numerical simulation results confirm the theoretical predictions

A Review of Ethical Leadership and Other Ethics- Related Leadership Theories

The role of ethics in leadership studies is very important for organizations. Leadership without ethics and integrity can be harmful both for the organizational stakeholders and society. The high-profiled scandals and the leadership involvement in unethical activities caused increase attention of the scholars and mainstream media in the leadership ethics (Hartog, 2015). This resulted a growing research in the field of ethical leadership behavior. For this reason, the present study review ethics-related leadership including ethical leadership and other ethic-related leadership theories to better understand the importance of the ethics and morality in these leadership constructs. This study also presented a comprehensive review on ethical leadership and its similarities and differences with other related leadership styles. Another focus of this study was to present the definitions of each leadership style and their scales, and to establish that how ethical leadership is distinct from each leadership style. Future directions and conclusion are presented in the last of the paper
