Enhancing a Transition to a Circular Economy in the Water Sector: The EU Project WIDER UPTAKE
2021
A novel approach for resource recovery includes forward osmosis (FO) as a concentration step in municipal wastewater treatment. The current study investigates different pre-treatment strategies including biological treatment with a moving-bed bioreactor (MBBR) at different loading rates and particle removal by filtration and sedimentation. Membrane performance and recovery potential for energy and nutrients were investigated in laboratory-scale FO experiments in batch mode using pre-treated municipal wastewater as feed and 35 g/L NaCl as a draw solution. Initial water fluxes were in the range of 6.3 to 8.0 L/(m2·h). The baseline fluxes were modelled to account for flux decline due to concen…
Nudging to prevent the purchase of incompatible digital products online: An experimental study.
2017
Ensuring safe and satisfactory online shopping activity, especially among vulnerable consumers such as elderly and less educated citizens, is part of a larger set of consumer policy objectives seeking to strengthen trust in the electronic marketplace. This article contributes to that goal by testing the effectiveness of nudges intended to prevent the purchase of 'incompatible' digital products (i.e., those which cannot be used with the devices owned by consumers or the systems they operate). We ran a computerised lab experiment (n = 626) examining three types of nudges, the effects of age and education, and interaction effects between these variables and the nudges. Results show that emotiv…
Using protection motivation theory in the design of nudges to improve online security behavior
2019
Abstract We conducted an online experiment (n = 2024) on a representative sample of internet users in Germany, Sweden, Poland, Spain and the UK to explore the effect of notifications on security behaviour. Inspired by protection motivation theory (PMT), a coping message advised participants on how to minimize their exposure to risk and a threat appeal highlighted the potential negative consequences of not doing so. Both increased secure behavior – but the coping message significantly more so. The coping message was also as effective as both messages combined, but not so the threat appeal. Risk attitudes, age and country had a significant effect on behavior. Initiatives seeking to promote se…
Privacy nudges as policy interventions: comparing US and German media users’ evaluation of information privacy nudges
2017
ABSTRACTThe protection of individuals’ online privacy is one of the main challenges for Internet policy. As the informed consent paradigm has largely failed to ensure privacy protection online, we examine nudging as a tool of soft paternalism as an alternative intervention to sensitize users towards online privacy. Building upon the criticism that nudging is considered being manipulative and reducing people’s autonomy in decision-making, we inquire how media users themselves evaluate nudges’ effectiveness and intrusiveness. In particular, we distinguish nudges either as targeting heuristic decision-making (system 1) or deliberate decision-making through education and information (system 2).…
