The focus of this contribution is to define speech acts as institutional actions where modeled institutions are social or informal institutions. With social or informal institution, we mean an institution which is grounded on the acceptances of its members. In the first part of the paper we present a logic of acceptance, goal and action. Then, we specify how agents can create and maintain normative...
Comprehending an unfamiliar code fragment requires an awareness of explicit usage directives that may be present in the documentation of some invoked functions. Since it is not practical for developers to thoroughly investigate every call, directives may be missed and errors may occur. We previously reported on a tool called eMoose, which highlights calls to methods with associated directives, and...
This paper describes a study which aim is to evaluate the effectiveness of podcasting technology in teaching online courses. A sample group of 104 students, with an optional access to audio recordings (podcasts) of the course, completed an online questionnaire. Some ANOVA tests were done to compare the group of students who listened to the online recordings (33) with those who did not (71). The results...
Test-driven development (TDD) is a development discipline prescribing writing tests beforehand writing the implementation code, which then shall pass the tests. Several criticisms addressed TDD's capability of delivering well-structured code, mainly because of the short focus on the features needed right now without much looking forward. So the main threat possibly introduced by TDD lies in the lack...
Since several years lecture recordings have intensively been used as a teaching tool. Several courses are provided with lecture recordings as complementary learning material. Several distribution variants of lecture recordings have been investigated. Podcasts have established as a comfortable distribution technology for lecture recordings and are now established as a regular service for lecturing...
One of the motives for studying faces and gestures is the role that they play in spontaneous, socially rich interaction between humans. If computers are to interact with humans in that mode (or to analyse what they are doing in it), methods of interpreting the non-verbal signals that they use are critical. It is becoming clear that developing those methods requires databases whose complexity is of...
