In the Weighted Total Acquisition problem (WTA) on a weighted graph G (only positive non-zero weights), vertex v can acquire total weight of neighbour u if and only current is at least that u. The new then zero, sum weights just before acquisition. Over all possible acquisition sequences in with function w, minimum number vertices end denoted by at(G,w). Given G, weighting an integer k?1, WTA a...

Delivering individualized services that conform to the user’s current situation will form the focus of ubiquitous environments. A description of the networked environment at a semantic level will necessitate contextually oriented knowledge acquisition methods. This then engenders unique challenges for the crucial step of resource discovery. A number of service discovery protocols exist to perfo...

Group Support Systems (GSS) technology, extensively applied in decision-making contexts, is now seeing increased application in the educational sector. Previous work has suggested that GSS applications can have significant positive effects on both the process and the outcome of collaborative learning. This study extends this work to examine the effects of process (high/low) and content (high/lo...

Scholars have found contradictory effects of strong ties in interfirm relations. They are considered both beneficial and detrimental for knowledge acquisition and innovation. In consequence, the debate on this paradox is flourishing. We wish to contribute to the discussion using a construct –relational bondingoriginally developed in studies on vertical interfirm relationships in business-to-bus...
