What are the best ways for design teams attend to issues of power, inequity, trust and other ethical concerns as they arise in design? Literature on value-sensitive design (VSD) and technology ethics has advocated for a range of design methods that propose different roles and responsibility for ethics during technology development. This paper explores four provocations that imagine different ro...

The content of many communication services depends on the context, such as the user’s location. We describe a ’service’ URN that allows to identify context-dependent services that can be resolved in a distributed manner.

Event-based systems are well suited for application in sensor networks. Compared to the traditional application domains of event-based systems however sensor networks impose a number of challenging requirements. In this short paper, we present an architecture designed to address these requirements: the CoDED platform for context-dependent event detection.

In interactive speech applications the expected vocabulary and the expected user utterances change from one dialogue step to the next one. The use of several context dependent language models results in a better system performance than the use of a single model. In this paper we present a new approach combining syntactical and statistical language constraints to a single language model. Recogni...

The content of many communication services depends on the context, such as the user’s location. We describe a ’service’ URN that allows to register such context-dependent services that can be resolved in a distributed manner.

If A is a context-free language over a two-letter alphabet, then the set of all words obtained by sorting words in A and the set of all permutations of words in A are context-free. This is false over alphabets of three or more letters. Thus these problems illustrate a difference in behavior between twoand three-letter alphabets. The following problem appeared on a recent exam at Cornell: Let be...

In German, wh-questions and verb-second wh-exclamatives are string-identical and can only be distinguished by intonation. This study presents data from a production experiment where speakers produced contextualized questions and exclamatives, showing that the two sentence types differ in many acoustic measures throughout the clause. The results also indicate that the realization of both sentenc...

This paper focuses on relationships between agent models and their physical realisations. Approaches on reduction from philosophical literature are analysed in a formalised manner, and extended by incorporating context-dependency w.r.t. specific makeups for their realisations. It is shown how these context-dependent reduction approaches can be translated into each other and how they can be appl...

Pollution prevention is an approach for generating less waste using fewer toxic chemicals while conserving water and energy. Even though pollution practices have been encouraged over thirty years, many smaller businesses not considered or adopted such techniques. This study examines the effect of a community-based designed to emphasize benefits health economic well-being urban communities when ...
