The fifth-wave of economic development began in the 1990s with a two-fold interest in providing market solutions and regional strategies for development. The idea of a comparative advantage has been integral to the development of the fifth-wave. This wave has been marked by economic developers who work to emphasize unmet demand, function as a ...
In Smihula theory technological revolutions are the main engine of economic development, and hence long-term economic cycles are dependent on these waves of technological innovation. [7] Smihula identified during the modern age in society six waves of technological innovations begun by technological revolutions (one of them is a hypothetical ...
The phase velocity varies with frequency. The phase velocity is the rate at which the phase of the wave propagates in space. The group velocity is the rate at which the wave envelope, i.e. the changes in amplitude, propagates. The wave envelope is the profile of the wave amplitudes; all transverse displacements are bound by the envelope profile.
Long wave theory is not accepted by many academic economists. However, it is important for innovation-based, development and evolutionary economics . Yet, among economists who accept it, there has been no formal universal agreement about the standards that should be used universally to place the start and end years for each wave.
Development theory is a collection of theories about how desirable change in society is best achieved. Such theories draw on a variety of social science disciplines and approaches. In this article, multiple theories are discussed, as are recent developments with regard to these theories.
The forming–storming–norming–performing model of group development was first proposed by Bruce Tuckman in 1965, [1] who said that these phases are all necessary and inevitable in order for a team to grow, face up to challenges, tackle problems, find solutions, plan work, and deliver results. He suggested that these inevitable phases were ...
Stage theories of development rest on the assumption that development is a discontinuous process involving distinct stages which are characterized by qualitative differences in behavior. They also assume that the structure of the stage is not variable according to each individual; however the time of each stage may vary individually. [ 1 ]
In historical linguistics, the wave model or wave theory (German: Wellentheorie) is a model of language change in which a new language feature (innovation) or a new combination of language features spreads from its region of origin, being adopted by a gradually expanding cluster of dialects.
