Mobile crowdsourcing provides us various exciting and profitable applications. All the mobile crowdsourcing systems purchase sensing services from a population of smartphone users. The issue of competition arises. However, few studies address this issue, which significantly affects the functionality of crowdsourcing systems. In this paper, we study the problem of price competition among multiple crowdsourcers in a free market, where smartphone users are able to withdraw from the current crowdsourcer if they can gain more utility from other crowdsourcers. We formulate the price competition as a dynamic non-cooperative game, where each crowdsourcer independently decides its own price aiming at highest profit and all smartphone users join the crowdsourcers at their satisfaction. In practice, a crowdsourcer may not know strategies of others which are unrevealed information. We propose a distributed learning algorithm that every crowdsourcer learns from its historic information to achieve the Nash equilibrium in the market. We studied and identified the suitable learning speed to make the price adaption converge to the Nash equilibrium. All the results are supported by both theoretical analysis and simulations.

A free and open press is a critical piece of the civil-society infrastructure that supports both established and emerging democracies. However, as the professional activities of reporting and publishing are increasingly conducted by digital means, computer security and privacy risks threaten free and independent journalism around the globe. Through interviews with 15 practicing journalists and 14 organizational stakeholders (supervising editors and technologists), we reveal the distinct-and sometimes conflicting-computer security concerns and priorities of different stakeholder groups within journalistic institutions, as well as unique issues in journalism compared to other types of organizations. As these concerns have not been deeply studied by those designing computer security practices or technologies that may benefit journalism, this research offers insight into some of the practical and cultural constraints that can limit the computer security and privacy practices of the journalism community as a whole. Based on these findings, we suggest paths for future research and development that can bridge these gaps through new tools and practices.
