What does PE stand for?

Written for scholars of scientific and philosophical disciplines, this volume explores Gould's thoughts on punctuated equilibrium, human equality and intelligence testing, "spandrels" and "exaptation" and the debate between science and fundamentalist Christianity.

2) We have resisted becoming a participant in such a ratcheting process, by which periods of punctuated equilibrium periodically occur in which the law lurches in the direction favored by Justice Douglas and his philosophical allies, during which new precedents arise bearing little more than a random relationship to the written law, only to be followed by periods of conservative judicial rule in which these new precedents are affirmed in the interests of stare decisis and become a permanent fixture of the law.

Sample topics include disjointed incrementalism, punctuated equilibrium models, cost benefit analysis, queuing theory, and Confucian decision making.

Further, we can infer from Gersick's punctuated equilibrium construct that different teams develop differently and that they progress bidirectionally through group development phases.

While punctuated equilibrium (PE) reflected in the fossil record is a strong negative evidence to the underlying principle of phyletic gradualism (PG) enshrined in the evolutionary theory, the phenomenon of cell-directed mutagenesis challenges another tenet of the theory, namely, the requirement of stochastic mutations produced by extra-cellular agents to create heritable changes in the organism.

The book is sown through with a vocabulary of adaptive organisms, fitness, punctuated equilibrium, replication and other concepts from evolutionary science.

He perceptively points out, for example, that the Phenomenon had already anticipated Gould's and Eldredge's celebrated theory of punctuated equilibrium without labeling it as such.

We also learned that the lifecycle of an initiative like ERA can be described as a punctuated equilibrium.
