Diffusion - is (literally), dispersion, spreading, spread.Physically, this concept describes the process of transfer of energy or matter from the highly concentrated area in a region with a reduced concentration.The most common occurrence, that is associated with diffusion - this mixing of gas molecules (e.g., when the fragrance is distributed in the air) or liquids.The same process can be observed in solids.For example, if the end of the rod is electrically charged or heat, the heat (or charge) will gradually spread from the hot end to the cold.At the same time if you take a piece of metal, the heat will spread quite rapidly, and the electric current - instantly.If the rod is made of synthetic material, the thermal distribution will be slow and the electric - even slower.Diffusion of solids occurs to a still lower speed.
should be noted that the term (and many others) used today, not only in physics.
There is, for example, such a thing as the diffusion of innovation.It's a process, by which time the transfer of innovations implemented by economic entities communication channels.In this case, diffusion - a distribution information, speed and shape depend on the used communication channels.Are of great importance and especially the perception of information entities conducting business activities as well as their ability to practical application of findings.When the diffusion of innovation, has mastered once and use in other areas, in new places and conditions is increasing the number of consumers and producers.The continuity of the process of forming the boundaries of form and dissemination of innovations in the market economy.
Experts point out that in terms of economic activity has the character of a cyclical diffusion.At the same time the implementation of the entire process of deployment, diffusion of innovations is divided into certain stages: basic and applied research, development and design, construction, development, and manufacturing, marketing and sales.
cultural diffusion - a concept that is used in the social sphere.This definition characterizes the process of mutual penetration of some features from one social group to another when they come in contact.Thus diffusion can and leave no imprint on any of interacting cultures.It may, however, also happen that this penetration will trigger a strong and equal (or unilateral) influence.The channels through which the diffusion takes place - it is mainly tourism, migration, war, trade, conferences, trade fairs and exhibitions, exchange of specialists and students.
Dissemination of innovations in the social sphere can be two directions: horizontally or vertically.
horizontal penetration (between-group diffusion) is celebrated between individuals, groups, equal in status.
vertical proliferation takes place between actors having unequal status.This process is called stratification diffusion.
traditional society is characterized by a pronounced symbolic polarization of the population.According to a number of cultural studies, an example of lifestyle and style of today (both higher and lower class) is considered middle class.
cultural diffusion brings to society, both positive and negative features.Thus, the spread of high conceptions of life in the medium and (especially) the lower strata of meaning, on the one hand, the democratization of education and the people.On the other hand, high culture in this case could be perceived primitive and vulgar.
