Collaborative Appropriation: How Couples, Teams, Groups and Communities Adapt and Adopt Technologies
Previous workshops and papers have examined how individual users adopt and adapt technologies to meet their own local needs, by “completing design through use.” However, there has been little systematic study of how groups of people engage collaboratively in these activities. This workshop opens a discussion for these under-studied forms of collaborative appropriation, using a broad range of pe...
In this paper, we provide an analytical perspective on the link between supply chain collaboration and forecast accuracy, showing that collaborative forecasting can lead to less accurate demand forecasts over a wide range of cost and demand parameters. The result is explained by the decision maker’s relative preference for investing in forecasting vs. order quantities to manage demand uncertain...

Serious games can facilitate workplace learning, for instance when collaboration on solving professional problems is involved. The optimal structure in collaboration scripts for such games has appeared to be a key success factor.

Collaborative filtering is a popular technique for recommending items to people. Several methods for collaborative filtering have been proposed in the literature and the quality of their predictions compared in empirical studies. In this paper, we argue that the measures of quality used in these studies are based on rather simple assumptions. We propose and apply additional measures for compari...

User attribute information associated with a user's ...
