input: Shoaling and schooling

It would seem reasonable to think that the regular spacing and size uniformity of fish in schools would result in hydrodynamic efficiencies. However, experiments in the laboratory have failed to find any gains from the hydrodynamic lift created by the neighbours of a fish within a school, though it is still thought that efficiency gains do occur in the wild. Landa (1998) argues that the leader of a school constantly changes, because while being in the body of a school gives a hydrodynamic advantage, being the leader means you are the first to the food.

input: Rubeus Hagrid

During the climactic battle, Hagrid attempts to come to the defence of Aragog's carnivorous children, who have been driven out of the Forbidden Forest by the Death Eaters and are now attacking both Hogwarts defenders and Death Eaters indiscriminately, but he is carried off by a swarm of them. He later turns up, captive in the Death Eaters' camp, when Harry sacrifices himself to Voldemort. Hagrid is forced to carry Harry back to the school, not realising that Harry has survived again, and en route accuses the watching Centaurs of not doing enough to help. The Centaurs soon afterward join the fray and Hagrid takes part in the second half of the battle, felling his main nemesis among the Death Eaters, the magical-creature executioner Walden Macnair.

input: Kellogg's

From 1969 to 1977, Kellogg's acquired various small businesses including Salada Foods, Fearn International, Mrs. Smith's Pies, Eggo, and Pure Packed Foods; however, it was later criticized for not diversifying further like General Mills and Quaker Oats were. After underspending its competition in marketing and product development, Kellogg's U.S. market share hit a low 36.7% in 1983. A prominent Wall Street analyst called it ''a fine company that's past its prime'' and the cereal market was being regarded as ''mature''. Such comments stimulated Kellogg chairman William E. LaMothe to improve, which primarily involved approaching the demographic of 80 million baby boomers rather than marketing children-oriented cereals. In emphasizing cereal's convenience and nutritional value, Kellogg's helped persuade U.S. consumers age 25 to 49 to eat 26% more cereal than people of that age ate five years prior. The U.S. ready-to-eat cereal market, worth $3.7 billion at retail in 1983, totaled $5.4 billion by 1988 and had expanded three times as fast as the average grocery category. Kellogg's also introduced new products including Crispix, Raisin Squares, and Nutri-Grain Biscuits and reached out internationally with Just Right aimed at Australians and Genmai Flakes for Japan. During this time, the company maintained success over its top competitors: General Mills, which largely marketed children's cereals, and Post, which had difficulty in the adult cereal market.
