Semantically rich domains require operative knowledge to solve complex problems in real-world settings. These domains provide an ideal environment for developing authentic constructivist e-learning environments. In this paper we present a framework and a methodology for developing authentic learning environments for such domains. The framework is based on an ecological view and characterizes di...

Titan Healthcare was founded in 1975 by a group of doctors who wanted to do healthcare differently. They realized that the Fee-ForService model of providing healthcare was inefficient and didn’t accurately address the total healthcare needs of the patient. Rather, it increased the costs by encouraging doctors to perform more services than necessary, and to not pay close attention preventative m...

Just-in-Time Teaching (JiTT) is an innovative method that enables faculty to increase interactivity in the classroom and engage students in learning. By creating a feedback loop between students’ work at home and the classroom setting, time on task is improved in both quality and quantity. This paper includes an introduction to JiTT and evidence of its effectiveness. It concludes with a discuss...

In this paper we introduce a distinction between two forms of planning: Just-in-Case planning versus Just-in-Time planning. The first refers to the traditional mode of planning as currently practiced in most urban and regional planning agencies, whereas the second, is what planning in a self-organizing system might be. The key notion behind this distinction is Just-in-Time— a method of producti...

We prove Fraenkel’s conjecture for the special case of symmetric words, and show that this proof implies the conjecture of Brauner and Crama [Facts and questions about the maximum deviation just-in-time scheduling problem, Discrete Appl. Math. 134 (2004) 25–50] concerning instances of the just-in-time sequencing problem with maximum deviation B∗< 1 2 . © 2007 Elsevier B.V. All rights reserved.

We consider a failure-prone manufacturing system with bursty demand arrivals. We prove that the hedging-point policy is optimal for this problem and provide analytical expressions to compute the hedging point. This allows us to compare our exact results to approximations provided by diiusion limits and large deviations. We also show that our result leads to the solution for the constant demand ...

This paper focuses on the problem of information overload for newcomers in an organisation. We propose to address it by constructing a smart personal training assistant based upon workflow tools to drive temporal management of a just-intime workplace training system which will deliver a personalised and structured presentation of organisational documents.

Accepting that learning is dialogic necessitates the development of teaching and learning activities that support a learning-conversation. Further, Blended Learning requires learning technologies to support the conventional teaching settings by constructing activities that enhance, rather than simply replace, the conventional teaching settings. Just-in-Time Teaching is one such strategy that ac...
