With the remarkable increase of data, novel tools and metrics are needed for comprehensive and systemic analyses of converging business ecosystems. Knowledge discovery is the computational process of identifying valid, novel, interesting, potentially useful and ultimately understandable patterns in data. The objective of our study is twofold. First, we introduce the emerging domain of "big" business ecosystem data. Second, we describe the success and challenges that we encountered in analyzing this data using state of the art analytics and visualization techniques.

We introduce Bit Whisperer, an ad-hoc short-range wireless communication system that enables "walk up and share" data transmissions with "good enough" security.

Prior research has produced mixed results regarding the usefulness of interactivity in multimedia learning. In this study, participants learned to solve part of a Rubik's Cube using either a tutorial with interactive features or a passive (video-based) tutorial. Participants with low spatial ability benefited more from interactivity than those with high ability, though no performance main effects were found between the tutorials. Targeted use of interactivity could be effective in engaging students and help them learn.
