Abbas, A.E. (author), van Velzen, Thomas (author), Ofe, H.A. (author), van de Kaa, G. (author), Zuiderwijk-van Eijk, A.M.G. (author), de Reuver, Mark (author)In the data economy, data sovereignty is often conceptualized as data providers’ ability to control their shared data. While control is essential, the current literature overlooks how this facet interrelates with other sovereignty facets and contextual conditions. Drawing from social contract theory and insights from 31 expert interviews, we...journal article 2024

Badshah, Munzar (author), Mehdi, Shozab (author), Alam, Kamran (author), Khan, K.I. (author), Abbas, Imran (author), Iezzi, Lorenzo (author), Segneri, Valentina (author), Stoller, Marco (author)A wide amount of existing building materials and consumables contains formaldehyde (HCHO) that may be released as a gas even after installation. The produced gas may concentrate in housing and offices, leading to a long-term exposure of the occupants. Living in such an environment, even at low concentrations less than 0.5 ppm, may lead to...journal article 2024

de Reuver, Mark (author), Ofe, H.A. (author), Agahari, W. (author), Abbas, A.E. (author), Zuiderwijk-van Eijk, A.M.G. (author)Data platforms are the keystone of the data economy. When opened up, data platforms allow data owners, data consumers and third parties to interact. Yet, openness may also harm business and societal interests. Literature on platform openness does not cover data platforms, and data economy scholars rarely study platform openness. Therefore, this...conference paper 2022
