In this paper, we use a computer simulation to explore the effects of dynamic capabilities on the evolution of business processes. Dynamic capability is conceptualized as variation and selective retention (Campbell, 1965; Bickhard and Campbell, 2003) which governs the development and adaptation of business process. The model demonstrates that variation and selective retention of business proces...

Populations of Physalaemus petersi show extraordinary variation in the expression of facultative complex calls. Previous studies have shown that a structure in the larynx, the fibrous mass (FM1), is correlated with variation in production of the complex call among taxa in the Physalaemus pustulosus species group. We tested the hypothesis that the variation in the presence of call complexity tha...

The existence of substantive parametric variation in syntax, as characterized in Chomsky 1981, has been questioned in the more recent generative literature, notably in Borer 1984, Fukui 1986, and Chomsky 1993. This article provides converging evidence from child language acquisition and comparative syntax for the existence of a syntactic parameter in the classical sense of Chomsky 1981, with si...

The Spike-heeled Lark Chersomanes albofasciata is a peculiar, short-tailed lark confined to southern, central and East Africa. Typical of resident larks, it exhibits marked geographic variation in ...
