Village elections in China present scholars with the case of a single-party regime that allows voters to reject candidates regularly. Using a micro survey of 698 voters in 30 rural election districts, the authors demonstrate that when some candidates can lose, voters participate. A comparison of models of voter turnout and running for office further demonstrates that even when competition is st...

Visiting museums is an increasingly popular pastime. Studies have shown that visitors can draw on their museum experience, long after their visit, to learn new things in practical situations. Rather than viewing a visit as a single learning event, we are interested in ways of extending the experience to allow visitors to access online resources tailored to their interests. Museums typically hav...

The paper starts with a discussion of the roles an organizational memory (OM) should play and what kind of knowledge should go into it. We then identify two kinds of integration problems. The rst one is concerned with integrating the knowledge bases of diierent knowledge-based systems employed in an organization into one physically or virtually uniied knowledge base which is to be considered as...

This paper describes a way of recognizing equivalent knowledgebased diagnosis applications at knowledge level, based on the notion of Conceptual Equivalence, that is formally developed. This notion of Conceptual Equivalence induces the definition of a generic inference structure for knowledge-based diagnosis applications named COPE, acronym for Compare, Observe, Predict and Evaluate.

The support of technological resources in teaching and learning has contributed to make them more efficient and enjoyable. Through this support has become quite common to use media resources before explored only for entertainment for educational purposes, among them the TV. The interactive Digital TV (iDTV) provides resources that make possible the development of a plethora of educational appli...

Recently, distillation approaches for extracting general knowledge from a teacher network to guide student have been suggested. Most existing methods transfer the by feeding sequence of random minibatches sampled uniformly data. We argue that, instead, compact should be guided gradually using samples ordered in meaningful sequence. Thus, gap feature representation between and can bridged step s...
