The distributions of a wide variety of physical, biological, and human-made phenomena approximately follow a power law over a wide range of magnitudes: these include the sizes of craters on the moon and of solar flares, [2] cloud sizes, [3] the foraging pattern of various species, [4] the sizes of activity patterns of neuronal populations, [5] the frequencies of words in most languages ...
The concepts of fluid intelligence (g f) and crystallized intelligence (g c) were introduced in 1943 by the psychologist Raymond Cattell. [ 1 ] [ 2 ] [ 3 ] According to Cattell's psychometrically -based theory, general intelligence ( g ) is subdivided into g f and g c .
Now Fluid Concepts and Creative Analogies presents that model, along with the computer programs Hofstadter and his associates have designed to test it. These programs work in stripped-down yet surprisingly rich microdomains. On April 3, 1995, Fluid Concepts and Creative Analogies became the first book ordered online by an Amazon.com customer. [3]
[5] [6] Preferential attachment and the fitness model have been proposed as mechanisms to explain conjectured power law degree distributions in real networks. Alternative models such as super-linear preferential attachment and second-neighbour preferential attachment may appear to generate transient scale-free networks, but the degree ...
Social simulation is a research field that applies computational methods to study issues in the social sciences.The issues explored include problems in computational law, psychology, [1] organizational behavior, [2] sociology, political science, economics, anthropology, geography, engineering, [2] archaeology and linguistics (Takahashi, Sallach & Rouchier 2007).
Pierre Bourdieu (French: [pjɛʁ buʁdjø]; 1 August 1930 – 23 January 2002) was a French sociologist and public intellectual. [4] [5] Bourdieu's contributions to the sociology of education, the theory of sociology, and sociology of aesthetics have achieved wide influence in several related academic fields (e.g. anthropology, media and cultural studies, education, popular culture, and the arts).
(1) Rational Choice Theory and James S. Coleman: After his 1964 pioneering Introduction to Mathematical Sociology, Coleman continued to make contributions to social theory and mathematical model building and his 1990 volume, Foundations of Social Theory was the major theoretical work of a career that spanned the period from 1950s to 1990s and ...
The statistical theory of turbulence in viscous liquids describes the fluid flow by a scale-invariant distribution of the velocity field, which means that the typical size of the velocity as a function of wavenumber is a power-law. In steady state, larger scale eddies at long wavelengths disintegrate into smaller ones, dissipating their energy ...
