This paper proposes an approach to capturing and reviewing scientific literature addressing latent topics across multiple scientific fields. As latent topics like moral values are affected by word polysemy and synonymy, a traditional keyword-based approach is often ineffective and therefore inappropriate. As a result, scientific literature addressi...

This paper aims to anticipate social acceptance issues related to the deployment of the smart electricity grid by identifying underlying value conflicts. The smart electricity grid is a key enabler of the energy transition. Its successful deployment is however jeopardized by social acceptance issues, such as concerns related to privacy and fairness...

This paper explores capability conflicts in the deployment of decentralised energy systems and identifies the affected population. These systems have positive societal impacts in terms of sustainability and consumer empowerment, but they are not accessible to all and their deployment may increase socio-economic inequalities. The societal impacts of...

This paper demonstrates an approach to assess, ex ante, the social acceptance of sustainable heating systems in city districts. More sustainable heating systems are required in city districts to reduce greenhouse gas emissions. However, these systems may lack social acceptance as they often require significant adjustments to homes and may lead to a...

According to a recent report of the Intergovernmental Panel on Climate Change (IPCC 2018), nuclear energy will play an important role in all scenarios in which global temperature rise is limited to 1.5°C above pre-industrial levels. One scenario even anticipates a sixfold increase in nuclear energy by 2050. These projections raise questions about t...

We study value change due to the corona pandemic. With the help of topic modelling, we analysed COVID-related news articles for changes in the frequency of how often these news articles address eleven different values. We looked at news articles from six countries (US, UK, South Africa, India, Japan, South Korea) and new articles spanning a longer...

Supported by the arrival of 5G/6G, we seem to be moving towards an AI-driven internet of robotic and bionano things. ‘AIoT’ (AI and IoT merging), ‘IoRT’ (IoT and robotics merging) and ‘IoBNT’ (IoT and bionano tech merging) are upcoming new acronyms reflecting this blending of technologies. Blockchain, augmented reality and virtual reality add even...

This article aims to explore the use of cross-impact balances (CIB) to identify scenarios of value change. The possibility of value change has received little attention in the literature on value-sensitive design (VSD). Examples of value change include the emergence of new values and changes in the relative importance of values. Value change could...

We propose a new approach for tracing value change. Value change may lead to a mismatch between current value priorities in society and the values for which technologies were designed in the past, such as energy technologies based on fossil fuels, which were developed when sustainability was not considered a very important value. Better anticipatin...

Heterogeneity in the population characteristics and behaviour has since long been recognised as an important factor that could influence the adoption curve of innovations. Until the 1990’s, the various simulation paradigms available to simulate the innovation did not allow a convenient study of the effects of heterogeneity due to the lack of model...

This master thesis research report has been written as part of the master programme ‘Systems Engineering, Policy & Management’ of the Technology, Policy and Management at the Delft University of Technology. The purpose of this work is to identify a set of directions for policy that allows a large adoption of smart grid appliances on the scale of ci...

The rollout of smart grids is beneficial for allowing the entire electricity infrastructure to cope with the important production fluctuations that can be occasioned by renewable energy sources. The extent to which smart grid infrastructures are able to cope with production fluctuations is largely dependent on the extent to which households are wil...

Nuclear energy dependency, large vulnerability to socio-political factors, high wind and solar energy targets and progressive liberalization of the energy sector; those are some of the main challenges the French electricity sector is currently facing. This paper uses the multi-method Exploratory System Dynamics Modeling and Analysis to explore the...
