Performance is the lifeblood of a firm’s management. Performance itself depends on the adaptation of strategy based on learning and the environment. An important way that firms adapt their strategy is through imitation or mimetic isomorphism. Imitation implies a referent for such adaptations. This article seeks to determine who or what should serve as that referent. Accordingly, this...

Juvenile hormone (JH) and 20-hydroxy-ecdysone (20E) are highly versatile hormones, coordinating development, growth, reproduction and aging in insects. Pulses of 20E provide key signals for initiating developmental and physiological transitions, while JH promotes or inhibits these signals in a stage-specific manner. Previous evidence suggests that JH and 20E might modulate innate immunity,...
