We indicate how one can extend any dynamical system (namely, of nonlinearly coupled autonomous ordinary differential equations) so that the extended thereby obtained is either isochronous or asymptotically multi-periodic, namely its generic solutions are completely periodic with a fixed period tend asymptotically, in remote future, to such functions multi-periodic (or become only future). In al...

In April of 1992, a group of parallel computing vendors, computer science researchers, and application scientists met at a one-day workshop and agreed to cooperate on the development of a community standard for the message-passing model of parallel computing. The MPI Forum that eventually emerged from that workshop became a model of how a broad community could work together to improve an import...

The growing importance of enterprise risk management and the resulting integration efforts put the need for separate IT risk management frameworks in question. In this research we analyse common and distinct elements of the COSO enterprise risk management and ISACA Risk IT frameworks. The analysis affirms the hypothesis that separate IT risk management frameworks are redundant.

The term ‘learning organisation’ is now a common feature of museum management discourse and, by implication, raises the issue of how a museum itself learns about approaches to ‘learning’. As ‘learning in museums’ becomes a major focus for many museums, clearly formulated and institutionally supported ideas about ‘learning’ should be an essential part of our role in interpreting natural and cult...

We study how the distribution of other-regarding preferences develops with age. Based on a set of allocation choices, we classify each of 717 subjects, aged 8 to 17 years, as either egalitarian, altruistic, or spiteful. We find a strong decrease in spitefulness with increasing age. Egalitarianism becomes less frequent, and altruism much more prominent, with age. Females are more frequently clas...

This paper describes the findings arising from ongoing qualitative usability evaluation studies on mobile companion robotics in smart home environments from two research projects focused on socio-technical innovation to support independent living (CompanionAble and Mobiserv). Key findings are described, and it is stated that the robotic companion, the smart home environment, and external servic...
