Cultures are externally affected via contact between societies, which may also produceor inhibitsocial shifts and changes in cultural practices. War or competition over resources may impact technological development or social dynamics. Additionally, cultural ideas may transfer from one society to another, through diffusion or acculturation. In diffusion, the form of something (though not necessarily its meaning) moves from one culture to another. For example, hamburgers, fast food in the United States, seemed exotic when introduced into China. "Stimulus diffusion" (the sharing of ideas) refers to an element of one culture leading to an invention or propagation in another. "Direct Borrowing" on the other hand tends to refer to technological or tangible diffusion from one culture to another. Diffusion of innovations theory presents a research-based model of why and when individuals and cultures adopt new ideas, practices, and products.
In the example given, what seemed exotic when introduced into China but is common in the United States?
A: fast food

The mascot of Northwestern Athletics is Willie the Wildcat. The first mascot, however, was a live, caged bear cub from the Lincoln Park Zoo named Furpaw who was brought to the playing field on the day of a game to greet the fans. But after a losing season, the team, deciding that Furpaw was to blame for its misfortune, banished him from campus forever. Willie the Wildcat made his debut in 1933 first as a logo, and then in three dimensions in 1947, when members of the Alpha Delta fraternity dressed as wildcats during a Homecoming Parade. The Northwestern University Marching Band (NUMB) performs at all home football games and leads cheers in the student section and performs the Alma Mater at the end of the game.
Who did the athletic team blame for it's first losing season?
A: Furpaw

In domestic dogs, sexual maturity begins to happen around age six to twelve months for both males and females, although this can be delayed until up to two years old for some large breeds. This is the time at which female dogs will have their first estrous cycle. They will experience subsequent estrous cycles biannually, during which the body prepares for pregnancy. At the peak of the cycle, females will come into estrus, being mentally and physically receptive to copulation. Because the ova survive and are capable of being fertilized for a week after ovulation, it is possible for a female to mate with more than one male.
What does a female dog experience at sexual maturity?
A: first estrous cycle

Feathers being critical to the survival of a bird, require maintenance. Apart from physical wear and tear, feathers face the onslaught of fungi, ectoparasitic feather mites and birdlice. The physical condition of feathers are maintained by preening often with the application of secretions from the preen gland. Birds also bathe in water or dust themselves. While some birds dip into shallow water, more aerial species may make aerial dips into water and arboreal species often make use of dew or rain that collect on leaves. Birds of arid regions make use of loose soil to dust-bathe. A behaviour termed as anting in which the bird encourages ants to run through their plumage is also thought to help them reduce the ectoparasite load in feathers. Many species will spread out their wings and expose them to direct sunlight and this too is thought to help in reducing fungal and ectoparasitic activity that may lead to feather damage.
What do birds bathe in?
A:
water or dust
