The phenomenon of growth, decline and death-aging-has been the source of consider-able speculation (1, 8, 10). This cycle seems to be a more or less direct function of the meta-bolic rate and this in turn depends on the species (animal or plant) on which are super-imposed the factors of heredity

of people they contain and, further, that the people there are functions of an attraction-selection-attrition (ASA) cycle. The ASA cycle is proposed as an alternative model for understanding organizations and the causes of the structures, processes, and technology of organizations. First, the ASA framework

We hope to be able to provide answers to the following questions: 1) Has there been a structural break in postwar U.S. real GDP growth toward more stabilization? 2) If so, when would it have been? 3) What's the nature of the structural break? For this purpose, we employ a Bayesian approach

of the life cycle model in which consumers are patient enough to begin saving for retirement early in life: wealth is estimated to be far less sensitive to uncertainty than implied by that model. Instead, our results suggest that over most of their working lifetime, consumers behave in accordance

The Kuramoto model describes a large population of coupled limit-cycle oscillators whose natural frequencies are drawn from some prescribed distribution. If the coupling strength exceeds a certain threshold, the system exhibits a phase transition: some of the oscillators spontaneously synchronize

, they accelerated the development of new technology relevant to the peacetime economy and shifted the political and social framework in ways conducive to peacetime growth.3 The historical sequence of business cycles and trend periods results from these deviations of actual from optimal patterns

This paper builds upon research by Lee [1] concerning the token flow model, an analytical model for the behavior of dataflow graphs with data-dependent control flow, by analyzing the properties of cycles of the schedule: sequences of actor executions that return the graph to its initial state

Abstract—Temporal and geometrical decorrelation often pre-vents SAR interferometry from being an operational tool for sur-face deformation monitoring and topographic profile reconstruc-tion. Moreover, atmospheric disturbances can strongly compro-mise the accuracy of the results. In this paper, we
