Growing pool of public-generated bits like online social networking data provides possibility to sense social dynamics in the urban space. In this position paper, we use a location-based online social networking data to sense geo-social activity and analyze the underlying social activity distribution of three different cities: London, Paris, and New York. We find a non-linear distribution of so...

This article critically examines Jürgen Habermas’s theory of democracy as developed in Between Facts and Norms. In particular, it focuses on the concept of communicative power and argues that there is a crucial ambiguity in Habermas’s use of this concept. Since communicative power is the key normative resource that is supposed to counter the norm-free steering media of money and administrative ...

Nursing Open is an open access, pay to publish journal which is dedicated to the highest standards in open access publishing. We believe that authors should have the opportunity to make their work freely available to others to download and read, with the ensuing benefits that this entails, both for readers and authors. However, open access opens up further possibilities that are not always avai...

Social networks are known to stimulate the exchange and sharing of information among peers. Even more social networks can initiate a cooperation (e.g., people sharing music) and a collaboration (e.g., searching for collaborators for research works). However, social networks are not widely used as work resources (e.g., for help or support request) mostly due to missing coordination mechanisms. T...
