Are VLEs still worthwhile?

Community Water Fluoridation: is it Still Worthwhile?

Exercise testing post-MI: still worthwhile in the interventional era.

Valeur et al. report findings from a substudy of the DANAMI-2 trial. The paper describes the prognostic importance of a pre-discharge maximal exercise test following acute myocardial infarction in the era of aggressive reperfusion treatment of ST-elevation myocardial infarction (STEMI). Exercise testing has been validated and adopted for risk stratification before discharge in patients with acu...

Are approximation algorithms for consensus clustering worthwhile?

Consensus clustering has emerged as one of the principal clustering problems in the data mining community. In recent years the theoretical computer science community has generated a number of approximation algorithms for consensus clustering and similar problems. These algorithms run in polynomial time, with performance guaranteed to be at most a certain factor worse than optimal. We investigat...

Are Adjacency Lists Worthwhile in AllDifferent?

In our AllDifferent paper [3], there was a loose end. The graph algorithms always discover the graph as they traverse it, by querying variable domains. It might be more efficient to store the graph (and backtrack it) in the form of adjacency lists. This is done here, and we show that it doesn’t affect the main conclusions of the paper.

Learning Objects: Are They Serving Practitioners Working with VLES?

The purpose of this paper is to present a high-level discussion based on ongoing research with the aim of providing support to educational practitioners based on real shareability and reuse of learning objects. Consequently, the discussion is centred around the need for a data-base driven architecture for VLEs that supports real reuse and sharing of learning materials within the same VLE, and n...
