The cerapodan dinosaurs were an ornithischian clade that achieved a global distribution in the Cretaceous Period. The ichnological record suggests that these dinosaurs had evolved by the Middle Jurassic, but only a single cerapodan body fossil, an isolated femur from the Callovian of the UK, is known from this interval. In order to elucidate the ea...

The past two decades have seen many governments, especially in the developing world acknowledging the importance of financial inclusion.

While issues surrounding representation constitute a pressing concern that also impacts literature education, there are few studies that map out whether and how teachers concretely employ repre-sentational criticism in their teaching of literature. This article, therefore, addresses the question of what role representational criticism plays in lite...

Cliffed (and rocky) coasts are geomorphic features occurring in about 80% of the coastline of the world and are strongly influenced by a broad range of both natural and anthropogenic processes that may cause serious erosion problems. Since the sea wave motion is a fundamental driver of cliff erosion, the cliffs become sensitive to increasing of glo...
