The Winter\u27s Tale: Problem areas in text and production
This study examines William Shakespeare’s The Winter’s Tale concentrating on what have commonly been perceived to be its problem areas. The play contains a blend of fantasy and realism which has contributed to its divided reception from audiences, critics, and scholars. It is argued that this mixture is not a result of Shakespeare’s failing powers but evidence of a unique and highly theatrical style
Developmental selection and selforganization
Developmental selection is the differential survival and proliferation of developmental units, such as cellular lineages. This type of internal selection has been proposed as an explanation for diverse examples of self-organization, from the wiring of brains to the formation of pores on leaf surfaces. A general understanding of developmental selection has been slowed by failure to understand its relationship to familiar forms of genetical selection and evolution. I show the formal analogies between models of developmental selection and genetical selection. The general method I outline for the analysis of selective systems partitions self-organizing selective systems into generative rules that create variation and selective filters that move the population toward a target design. The method also emphasizes aggregate statistical measures of evolving systems, such as the covariance between particular traits and fitness. The identification of useful aggregate measures is a crucial step in the analysis of selective systems. I apply these concepts to a model of self-organization in ant colonies.
