Let β be the ratio of benefit to cost of an altruistic act controlling for trembles. In “Evolution and Information in a Gift Giving Game” [3] the stochastically stable strategy is found if β < 2 or β > 4. In this note the stochastically stable strategy is found for the intermediary range and the speed of evolution is bounded. It is shown that if β ≤ 3 then players are selfish in the long run, i...

The temporal evolution of the scientific world can also be delineated in the map. In particular, this map clearly shows a linear structure of the scientific world, which contains three major domains including physical sciences , life sciences, and medical sciences. The interaction of various knowledge fields can be clearly seen from this scientific world map. This approach can be applied to var...

The aim of the article is to analyze why the sustainable competitive advantage may disappear for many business organizations, and how to maintain the advantages in order to survive in the market. The paper proposes an evolution path of strategic literature, from the classical Porter’s strategic theory to business inertia, strategic resilience, then Organizational transformation, finally to the ...

Unlike Database Management Systems (DBMSs), Data Stream Management Systems (DSMSs) do not evaluate queries over static data sets — rather, they continuously produce result streams to standing queries, and often operate in a context where any interruption can lead to data loss. Support for schema evolution in such an environment is currently unaddressed. In this work we address evolution in DSMS...
