Gamification captured the attention of both marketing researchers and practitioners about a decade ago. Despite established conceptualization gamification as driver intrinsic motivation range empirical research on topic, there is still uncertainty its place tool. Some argue that acts customer engagement, others consider it an outcome process. Such dual nature raises question role which plays in...

We present a new proof of Stembridge’s theorem about the enumeration of totally symmetric plane partitions using the methodology suggested in the recent Koutschan-Kauers-Zeilberger semi-rigorous proof of the Andrews-Robbins q-TSPP conjecture. Our proof makes heavy use of computer algebra and is completely automatic. We describe new methods that make the computations feasible in the first place....

In-place reconstruction of differenced data allows information on devices with limited storage capacity to be updated efficiently over low-bandwidth channels. Differencing encodes a version of data compactly as a set of changes from a previous version. Transmitting updates to data as a version difference saves both time and bandwidth. In-place reconstruction rebuilds the new version of the data...
