Music is used extensively to evoke emotion throughout the customer journey. This paper develops a theory-based, interpretable deep learning convolutional neural network (CNN) classifier---MusicEmoCNN---to predict the dynamically varying emotional response to music.

The Freemium business model, commonly used in digital products, has both a perpetually free but limited version and a premium version with enhanced features that requires a fee. These firms often have a referral program in which current customers get additional benefits (e.g., extra storage...

This paper develops a strategy with simple implementation and limited data requirements to identify spatial distortion of supply from demand – or, equivalently, unequal access to supply among regions – in transportation markets. We apply our method to ride-level, multi-platform data from New...

Use of bacterial biochar for Cr(VI) removal opens room for new research in terms of cost effectiveness, better performance and high selectivity. This work reports the synthesis, physicochemical characterization and performance evaluation of bacterial biochar synthesized at 200oC and 400oC. To...
