Long Waves

 

radio waves with a wavelength of 1 km to 10-20 km. They may propagate because of diffraction of radio waves on the spherical surface of the earth at distances of up to 1,000-2,000 km. Long waves propagate over longer distances through the guide effect of the spherical atmospheric wave guide formed by the surface of the earth and the lower boundary of the ionosphere.

There will be two categories of participants, those who are requested to present papers suggesting potential solutions and those with special expertise in long wave propogation, analysis or mitigation.
The contests of the twentieth century--the long wave beginning with World War I, in which regime promotion pushed socialism, fascism, or liberalism--became particularly convoluted when the democracies appeared too weak to sustain economic development or to stand against the alternatives, and fascism was promulgated as the only reliable bulwark against communism.
Long waves of alternative industrial, social and ecological capitals may be on the horizon if a progressive SSA is successful in the future.
8) This reference to long wave motion for the states is purely short-hand language, and does not mean to imply that long waves motion necessarily operates for the states, as distinct from the national (or global) economy.
Given these views - and the correspondence each scholar has found between their hypothesized cycle and great-power war - it would seem we are left with three choices: (1) to believe that armed conflict is associated with long waves but not with hegemony, (2) to believe armed conflict is associated with the world leadership cycle but not with global economic fluctuations, or (3) to explore the possibility that both cycles may contribute in different ways to the generation of armed conflict.
In Section 3, unidirectional asymptotic wave equations governing small-but-finite amplitude long waves in the one-dimensional, nonlinear, nonlocal elastic models are summarized.

In his article, "The Next Decade in the Economy," CFA Readings, March 1987, he concludes that economic long waves primarily result from major shifts in the construction of physical capital and in the prices of physical capital.
