  2. Uses and gratifications theory - Wikipedia

    en.wikipedia.org/wiki/Uses_and_gratifications_theory

    Uses and gratifications theory was developed from a number of prior communication theories and research conducted by fellow theorists. The theory has a heuristic value because it gives communication scholars a "perspective through which a number of ideas and theories about media choice, consumption, and even impact can be viewed". [11] [12] [13 ...

  4. Bohr–Sommerfeld model - Wikipedia

    en.wikipedia.org/wiki/Bohr–Sommerfeld_model

    This allowed the orbits of the electron to be ellipses instead of circles, and introduced the concept of quantum degeneracy. The theory would have correctly explained the Zeeman effect, except for the issue of electron spin. Sommerfeld's model was much closer to the modern quantum mechanical picture than Bohr's.

    The law of effect, or Thorndike's law, is a psychology principle advanced by Edward Thorndike in 1898 on the matter of behavioral conditioning (not then formulated as such) which states that "responses that produce a satisfying effect in a particular situation become more likely to occur again in that situation, and responses that produce a ...

    In this case, the question (Q) is the native word, the answer (A) is the foreign word (written), and the pronunciation is always part of the answer (A*). This is particularly the case for character-based languages like Chinese hanzi and Japanese kanji , but it can also be used for other non-phonetic spellings such as English as a second language .

  8. Cardinal utility - Wikipedia

    en.wikipedia.org/wiki/Cardinal_utility

    The breakthrough occurred when a theory of ordinal utility was put together by John Hicks and Roy Allen in 1934. [19] In fact pages 54–55 from this paper contain the first use ever of the term "cardinal utility". [20] The first treatment of a class of utility functions preserved by affine transformations, though, was made in 1934 by Oskar ...

  9. Alphabet effect - Wikipedia

    en.wikipedia.org/wiki/Alphabet_effect

    It has been suggested (by e.g. Grosswiler 2004) that Schmandt-Besserat's research into the origin of writing from three-dimensional tokens gives an alternative to the progressivist account of the Alphabet Effect theory. Grosswiler suggests that it is the potential for recording memory, not any one system of it, that propels a culture towards ...
