Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. [1] The distance decay effect states that the interaction between two locales declines as the distance between them increases.
An example of such disputes is the proposal by Thor Heyerdahl that similarities between the culture of Polynesia and the pre-Columbian civilizations of the Andes are due to diffusion from the latter to the former—a theory that currently has few supporters among professional anthropologists.
"Diffusionism", in its original use in the 19th and early 20th centuries, did not preclude migration or invasion.It was rather the term for assumption of any spread of cultural innovation, including by migration or invasion, as opposed "evolutionism", assuming the independent appearance of cultural innovation in a process of parallel evolution, termed "cultural evolutionism".
Taylor saw geography in a synthesising role between explanations of the physical world and the diffusion and evolution of the human species. The fittest tribes evolve and survive in the most stimulating regions; i.e., where living is not so hard as to stunt mental development, and not so easy as to encourage sloth and loss of initiative.
Spatial diffusion is the gradual spread of culture, ideas, and institutions across space over time, in which the desirability of one place adopting the traits of a separate place overcome the friction of distance. Time geography explores how human activity is affected by the constraints of movement, especially temporal costs. [11]
[18]: 158 Kehoe concludes with the theory of transoceanic contact and makes clear that she is not asserting a specific theory of how and when cultures diffused and blended, but is instead offering a plausible, and testable, example of how civilizational similarities may have arisen without hyperdiffusionism, namely by independent invention and ...
Waldo Tobler in front of the Newberry Library. Chicago, November 2007. The First Law of Geography, according to Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." [1] This first law is the foundation of the fundamental concepts of spatial dependence and spatial autocorrelation and is utilized specifically for the inverse distance ...
The concept of diffusion is widely used in many fields, including physics (particle diffusion), chemistry, biology, sociology, economics, statistics, data science, and finance (diffusion of people, ideas, data and price values). The central idea of diffusion, however, is common to all of these: a substance or collection undergoing diffusion ...
