Whales Give Dolphins a Lift
Science Bulletins: Many species interact in the wild, most often as predator and prey. But recent encounters between humpback whales and bottlenose dolphins reveal a playful side to interspecies interaction. In two different locations in Hawaii, scientists watched as dolphins “rode” the heads of whales: the whales lifted the dolphins up and out of the water, and then the dolphins slid back down. The two species seemed to cooperate in the activity, and neither displayed signs of

3.4 Characterisation and sexual stereotyping

In attempting to characterise their sitters, 19th-century commercial photographers did not intend or attempt any serious psychoanalytical exploration of individual character such as we perceive it today in our post-Freudian world. They sought instead to stereotype by age and sex within a narrow range of positive virtues, which had previously been approved, within the conventions of painting: modesty, simplicity and chastity for women; dignity, strength and nobility for men.

Conclusion

All objects, irrespective of their mass, experience the same acceleration g when falling freely under the influence of gravity at the same point on the Earth. Close to the Earth's surface, g=9.8 m s−2. The weight of an object is the force F g due to gravity acting on the object, and for an object with mass m the weight is given by F g=mg.

If the height of an object of mass m changes by Δh, the ch

4.1 Introduction

Collective oeuvres* produce and sustain group solidarity. They help make a community. Works and works-in-progress create shared and negotiable ways of thinking in a group … externalising, in a word, rescues cognitive activity from implicitness, making it more public, negotiable and solidary.

(Bruner, 1996, p. 22)

*An oeuvre is normally defined as the total output of an individual writer or ar

7.1 History

So far, I have provided a brief historical background for England, Scotland, Wales and Northern Ireland, one that accounts for their distinctive identities and for the origins of their differing role within the UK. I have also defined devolution as an asymmetric decentralisation process which responds to the claims advanced by the nations constituting the UK state. What, then, do we mean by Britain? Is it a nation? If so, when did the British nation begin to exist? The historian Linda Colley
