Along with the theoretical and practical research on introducing a social dimension to adaptive educational hypermedia, the evaluation of such systems becomes more important. Existing evaluation methods are mostly based on statistical and qualitative analysis, in which researcher bias is built in and unavoidable. Moreover, they adopt either a traditional “as a whole” approach making it difficul...

The current research investigated whether mind-sets and contexts that afford a focus on self-other differences can facilitate perceptual and conceptual forms of perspective taking. Supporting this hypothesis, results showed that directly priming a difference mind-set made perceivers more likely to spontaneously adopt other people's visual perspectives (Experiment 1) and less likely to overimput...

As Director of the Office of Scientific Research and Development, Dr. Vannevar Bush has coordinated the activities of some six thousand leading American scientists in the application of science to warfare. In this significant article he holds up an incentive for scientists when the fighting has ceased. He urges that men of science should then turn to the massive task of making more accessible o...

While a great deal is known about how Information and Communication Technologies are used in developing and underserved communities, there are still gaps as to how ICTs may enable development outcomes to be achieved. It appears that the majority of businesses in developing regions are micro-enterprises which employ between 1-5 people and face challenges of limited resources. This research inves...

Motivated by the famous Waddington’s epigenetic landscape metaphor in developmental biology, biophysicists and applied mathematicians made different proposals to realize this metaphor in a rationalized way. We adopt comprehensive perspectives to systematically investigate three different but closely related realizations in recent literature: namely the potential landscape theory from the steady...
