Critical research into the gig economy frequently relies on using platform interfaces, mobile applications or websites, as intermediaries to contact and recruit participants. Yet, these methods are accompanied by significant ethical implications that rarely considered. In this article, we look at organisational features of interfaces for explore ways in which, through their intensive knowledge ...

The ability to perform meaningful empirical studies is of essence in research in spatio-temporal query processing. Such studies are often necessary to gain detailed insight into the functional and performance characteristics of proposals for new query processing techniques. We present a collection of spatio-temporal data, collected during an intelligent speed adaptation project, termed INFATI, ...

This paper introduces an information theoretic model that allows to quantify the degree of anonymity provided by schemes for anonymous connections. It considers attackers that obtain probabilistic information about users. The degree is based on the probabilities an attacker, after observing the system, assigns to the different users of the system as being the originators of a message. As a proo...
