This article is about something called ‘the platform’ which is currently a powerful metaphor for the way contemporary society organizes and understands itself. With a recent focus to ‘smarten up’ our cities, the contemporary position of platforms and how platforms are implicated in the structures that shape everyday life in the city are explored. M...

The smart city imaginary has become a recurring theme within critical urban geography and entails a distinct set of rationalities. Here, we are interested in grappling with the current ‘place’ of smart cities in the context of what seems to be an emerging platform urbanism, thereby highlighting a complex platform-based ecosystem encompassing privat...

This article explores the current 'place' of e-government in realizing public value in the context of what seems to be an emerging platform urbanism. It highlights a complex platform-based urban ecosystem encompassing private and public organisations and citizens. This 'mainstreaming' of e-government practices puts demands on cities and governments...

BACKGROUND In the European Union, around 5 million people are affected by psychotic disorders, and between 30-50% of people with schizophrenia have treatment-resistant schizophrenia (TRS). Mobile interventions may be effective in preventing relapses, increasing treatment adherence and managing some of the symptoms of schizophrenia. People with schi...

Prosumers can actively participate in electricity markets through new market models. Peer-to-peer, community self-consumption, and transactive energy are the three market models which are said to complement traditional electricity markets, enabling prosumers to create and capture value. To date, however, the characteristics of these models and ince...

The predominant rhetoric in smart city debates puts the emphasis on collaboration. Conceptualizing, designing, implementing, validating and evaluating solutions to urban challenges with all relevant stakeholders around the table is perceived as the optimal modus operandi in these perspectives. But how does this vision relate to current practices in...

Peer-to-peer electricity markets allow users to trade electricity among themselves thereby increasing their financial well-being. However, such markets also create opportunities for malicious players to misbehave in order to maximize their profits. Potential threats are impersonation, data manipulation, disputes and privacy breaches; users' offers...

This trust computational model relies upon survey research for identifying the set of key trust attributes and grouping users into four segments of expected...

This paper aims to unravel the intricacies of the mechanisms of trust vis-à-vis ICTs and the contextual logic guiding user deployment and experience, necessitating a view of trust in the digital realm as a dynamic process. Trust models tend to highlight ‘well-placed trust’ in their focus on drawing out (sub)components of (perceived) trustworthiness...

Media literacy has been defined as “the ability to access, analyze, evaluate and create messages across a variety of contexts” (Christ & Potter 1998, 7). This definition, produced by the USA’s 1992 National Leadership Conference on Media Literacy, is widely accepted, although many alternative and competing conceptions also exist. As the subject of a...
