Expansion diffusion: an innovation or idea that develops in a source area and remains strong there, while also spreading outward to other areas. This can include hierarchical, stimulus, and contagious diffusion. Relocation diffusion: an idea or innovation that migrates into new areas, leaving behind its origin or source of the cultural trait.
The sociological theory of diffusion is the study of the diffusion of innovations throughout social groups and organizations. The topic has seen rapid growth since the 1990s, reflecting curiosity about the process of social change and "fueled by interest in institutional arguments and in network and dynamic analysis."
Diffusion of innovations is a theory that seeks to explain ... The findings were that opinion leadership tended to be organized into a hierarchy within a society ...
Diffusion of ideas and innovations studies focus on the spread and use of ideas from one actor to another or one culture and another. This line of research seeks to explain why some become "early adopters" of ideas and innovations, and links social network structure with facilitating or impeding the spread of an innovation.
Diffusion of innovative ideas. The rate of the individual's decision making process is, therefore, a factor in the innovation's success. [25] [26] The variance between people's responses creates a normal distribution curve. Collar explains, "there is a point on the curve that represents the crux of the diffusion process: the ‘tipping point ...
The model of hierarchical complexity (MHC) is a formal theory and a mathematical psychology framework for scoring how complex a behavior is. [4] Developed by Michael Lamport Commons and colleagues, [3] it quantifies the order of hierarchical complexity of a task based on mathematical principles of how the information is organized, [5] in terms of information science.
Migrationism explains cultural change in terms of human migration, while diffusionism relies on explanations based on trans-cultural diffusion of ideas rather than populations (pots, not people [1]). Western archaeology the first half of the 20th century relied on the assumption of migration and invasion as driving cultural change.
Bayesian hierarchical modelling is a statistical model written in multiple levels (hierarchical form) that estimates the parameters of the posterior distribution using the Bayesian method. [1] The sub-models combine to form the hierarchical model, and Bayes' theorem is used to integrate them with the observed data and account for all the ...
