    Graves used a variety of names for his theory during his lifetime, ranging from the generic Levels of Human Existence in his earlier work [5] to lengthy names such as Emergent Cyclical, Phenomenological, Existential Double-Helix Levels of Existence Conception of Adult Human Behavior (1978) and Emergent Cyclical Double-Helix Model of the Adult Bio-Pyscho-Social Behaviour (1981).

  4. Cyclic model - Wikipedia

    en.wikipedia.org/wiki/Cyclic_model

    A cyclic model (or oscillating model) is any of several cosmological models in which the universe follows infinite, or indefinite, self-sustaining cycles. For example, the oscillating universe theory briefly considered by Albert Einstein in 1930 theorized a universe following an eternal series of oscillations, each beginning with a Big Bang and ending with a Big Crunch; in the interim, the ...

    The HP filter identifies the longer-term fluctuations as part of the growth trend while classifying the more jumpy fluctuations as part of the cyclical component. FIGURE 2. Observe the difference between this growth component and the jerkier data. Economists refer to these cyclical movements about the trend as business cycles. Figure 3 ...

    The cyclic model of succession was proposed in 1947 by British ecologist Alexander Watt.In a seminal paper on vegetation patterns in grass, heath, and bog communities, [4] Watt describes the plant community is a regenerating entity consisting of a "space-time mosaic" of species, whose cyclic behavior can be characterized by patch dynamics.
