Big Data is the new hype in municipal policy and the promise of Big Data is rationalization: better policy that is based on better information. In this article the authors investigate the extent to which the use of Big Data in municipal organizations results in a more rational policy process. Their empirical research was held in two Dutch municipalities: Tilburg, in the south of the Netherlands, and Assen, in the north of the Netherlands. They investigated how Tilburg deploys Big Data for the fight against crime and Assen is trying to improve its traffic management with Big Data. Their analysis shows that policy, more so than in the past, is being steered by specific information because Big Data is being used. The rationalization of policy, however, is limited by the possibilities of Big Data and by political dynamics. Their final conclusion therefore is that the uncertainty, unfamiliarity, complexity and constant change are partly made manageable and controllable by the use of Big Data in municipal organizations. Politics is also partly ‘tamed’ because politicians have to relate to ‘objective data’ from information systems.

Risks taken by some organizations may have considerable impact on society. In this contribution the assessment and management of risk are perceived to take place in a multi-actor setting. Within an organization operators, risk managers, and top managers interact about risk assessments and risk mitigation strategies. Public regulators and inspectorates increasingly focus on risk management systems instead of the operational activities or organizational outputs. Are organizations systematically assessing their risks? This contribution identifies two contrasting perspectives on risk assessment and risk mitigation in literature: risk management and risk governance. An empirical study in three sectors reveals evidence of both perspectives in practice. Companies adopt hybrid approaches, which are essential for the quality of risk assessment and mitigation. Indeed, adopting just one perspective seems dangerous. We conclude that public regulators and inspectorates might provide incentives to focus on just one perspective and suggest two heuristics for public inspectorates that respect hybrid approaches of risk assessment and mitigation.

Worldwide, cities are becoming increasingly important in global networks. The rise of cities and urban regions is widely described in academic literature. Cities are becoming essential players in networks on three scales: on an international scale as a hub in global networks, on a regional scale in partnerships as a consequence of the necessity of upscaling and on a local scale, in cooperation with citizens. This article addresses what this rise of the city, operating in complex networks on different scales, means for the position and tasks of the mayor, as a representative of the city. The article describes the modern challenges for the mayoral function and role in an emerging network society and addresses the growing importance of strong personal and transactional leadership while operating in networks both inside and outside the municipality.
