Leadership and the deified/demonic : a cultural examination of CEO sanctification

I examine in this paper deification and demonisation – the social attribution of absolute ‘Good’ and ‘Evil’ to individuals or individual entities. Specifically, I unpack ways that evilness and goodness have become personified in the figure of the chief executive officer in contemporary, particularly US, business culture. Showing both the readily accessible and widely used nature of these religious tropes, I nevertheless argue that both deification and demonisation have ethically and politically disempowering effects for organisational members, the wider citizenry, and for critique within the field of business ethics.

A truthful double auction for device-to-device communications in cellular networks

Data traffic in cellular networks has dramatically increased in recent years as the emergence of various new wireless applications, which imposes an immediate requirement for large network capacity. Although many efforts have been made to enhance wireless channel capacity, they are far from solving the network capacity enhancement problem. Device-to-Device (D2D) communication is recently proposed as a promising technique to increase network capacity. However, most existing work on D2D communications focuses on optimizing throughput or energy efficiency, without considering economic issues. In this paper, we propose a truthful double auction for D2D communications (TAD) in multi-cell cellular networks for trading resources in frequencytime domain, where cellular users with D2D communication capability act as sellers, and other users waiting to access the network act as buyers. Both intra-cell and inter-cell D2D sellers are accommodated in TAD while the competitive space in each cell is extensively exploited to achieve a high auction efficiency. With a sophisticated seller-buyer matching, winner determination and pricing, TAD guarantees individual rationality, budget balance, and truthfulness. Furthermore, we extend our TAD design to handle a more general case that each seller and buyer ask/bid multiple resource units. Extensive simulation results show that TAD can achieve truthfulness as well as high performance in terms of seller/buyer sanctification ratio, auctioneer profit and network throughput.
