Morning (2008) looked at high school biology textbooks during the 1952-2002 period and initially found a similar pattern with only 35% directly discussing race in the 198392 period from initially 92% doing so. However, this has increased somewhat after this to 43%. More indirect and brief discussions of race in the context of medical disorders have increased from none to 93% of textbooks. In general, the material on race has moved from surface traits to genetics and evolutionary history. The study argues that the textbooks' fundamental message about the existence of races has changed little.

Much of its technology and ideas were incorporated into the definition of ISO MPEG Audio Layer I and Layer II and the filter bank alone into Layer III (MP3) format as part of the computationally inefficient hybrid filter bank. Under the chairmanship of Professor Musmann (University of Hannover) the editing of the standard was made under the responsibilities of Leon van de Kerkhof (Layer I) and Gerhard Stoll (Layer II).
Who's responsibility was it to edit the standard for Layer I?

Bridgwater was developed during the Industrial Revolution as the area's leading port. The River Parrett was navigable by large ships as far as Bridgwater. Cargoes were then loaded onto smaller boats at Langport Quay, next to the Bridgwater Bridge, to be carried further up river to Langport; or they could turn off at Burrowbridge and then travel via the River Tone to Taunton. The Parrett is now only navigable as far as Dunball Wharf. Bridgwater, in the 19th and 20th centuries, was a centre for the manufacture of bricks and clay roof tiles, and later cellophane, but those industries have now stopped. With its good links to the motorway system, Bridgwater has developed as a distribution hub for companies such as Argos, Toolstation, Morrisons and Gerber Juice. AgustaWestland manufactures helicopters in Yeovil, and Normalair Garratt, builder of aircraft oxygen systems, is also based in the town. Many towns have encouraged small-scale light industries, such as Crewkerne's Ariel Motor Company, one of the UK's smallest car manufacturers.
