Literature on Mobile Platforms focuses predominantly on strategic issues in managing multi-sided platforms as well as economic issues of two-sided markets. Most of this literature is highly conceptual and empirical research on the perceptions, preferences and behaviour of consumers is lacking. Moreover, scholars typically focus on device-related platforms like operating systems and app stores, ...

In this paper we introduce a feature migration theory and use it to study the migratory behaviour of 1,324 Blackberry features, finding that 68% die, 2% migrate and 30% are intransitive (they neither die nor migrate). Intransitive features have significantly higher prices (p<0.05), and higher popularity, while customers appear to be less sensitive to their price. By contrast, migratory features...

The goal of this research is to evaluate the significance of riparian hosts in the epidemiology of Pierce’s disease (PD) in the North Coast grape-growing region of California. Our first objective is to examine the epidemiological role of seasonal Xylella fastidiosa (Xf) concentration fluctuations in riparian hosts in the field, where plants are subject to seasonal temperature changes. Among sys...
