Communication revolutions: early iPads?

iPads in early education: separating assumptions and evidence

Since their first appearance in 2010, iPads and other comparable tablets have been heralded for their potential to revolutionize education, including that of young children. Like previous multimedia technologies (e.g., whiteboards, Kozma, 1991), iPads are multimodal, allowing users to use texts, pictures, and sounds. In comparison with other, so far available multimedia technologies, iPads have...

Technological Revolutions

In skill-biased (de-skilling) technological revolutions learning investments required by new machines are greater (smaller) than those required by preexisting machines. Skill-biased (de-skilling) revolutions trigger reallocations of capital from slow(fast-) to fast(slow-) learning workers, thereby reducing the relative and absolute wages of the former. The model of skill-biased (de-skilling) re...

Oogenesis: Matrix Revolutions

The mechanism of egg-chamber elongation during Drosophila oogenesis has always been mysterious. A new study shows that the egg chambers spin around their long axis laying down polarised extracellular matrix, which acts as a molecular corset to restrict radial expansion.
