	abstract = {A total of 295 junior, intermediate and senior professional Java consultants (99 individuals and 98 pairs) from 29 international consultancy companies in Norway, Sweden and the UK were hired for one day to participate in a controlled experiment on pair programming. The subjects used professional Java tools to perform several change tasks on two alternative Java systems with different degrees of complexity. The results of this experiment do not support the hypotheses that pair programming in general reduces the time required to solve the tasks correctly or increases the proportion of correct solutions. On the other hand, there is a significant 84 percent increase in effort to perform the tasks correctly. However, on the more complex system, the pair programmers had a 48 percent increase in the proportion of correct solutions, but no significant differences in the time taken to solve the tasks correctly. For the simpler system, there was a 20 percent decrease in time taken but no significant differences in correctness. However, the moderating effect of system complexity depends on the expertise of the subjects. The observed benefits of pair programming in terms of correctness on the complex system apply mainly to juniors, whereas the reductions in duration to perform the tasks correctly on the simple system apply mainly to intermediates and seniors.},

	abstract = {This article presents our study of medical students in their medical practice and their use of mobile terminals, serving as information resources, in relation to the KNOWMOBILE project. The main objective is to shed light upon conditions for the possibility for use of mobile terminals, serving as an information resource, in contexts related to the medical practice. The title of the this article refers to our most distinct discovery: We observed a very limited use of the mobile terminal in the medical students{\textquoteright} practical training. We observed that they preferred to use other resources instead, and often left the mobile terminal at home or in the cloakroom at the practice location. When moving away from the medical contexts and the medical tasks, the use increased. Through literature studies, prototyping and empirical findings, we state that several aspects affect the use or more correctly: the non-use of the mobile terminal. We state that the use is dependent upon the characteristics and resources of the mobile terminal as well as the other information resources available in the context. In addition, we believe that because the use of the mobile terminal was not percieved as a part of the community of practice, the medical students did not find the mobile terminal useful in their medical practice period.},
