Division of labor is one of the most basic and widely studied aspects of colony behavior in social insects. Studies of division of labor are concerned with the integration of individual worker behavior into colony level task organization and with the question of how regulation of division of labor may contribute to colony efficiency. Here we describe and critique the current models concerned wi...

Why some species become invasive while others do not is a central research request in biological invasions. Clonality has been suggested as an attribute that could contribute to plant invasiveness. Division of labor is an important advantage of clonal growth, and it seems reasonable to anticipate that clonal plants may intensify this clonal attribute in an invaded range because of positive sele...

Firms exhibit heterogeneity in size, productivity, and internal structure, and this is true even within the same industry. Our paper provides evidence of a link between an organization’s culture—specifically the trust environment—and its level of specialization. We show experimentally that exogenously imposed culture endogenously leads to variation in organizational form. We prime trust and dem...

From microbes to humans, the success of many organisms is achieved by dividing tasks among specialized group members. The evolution of such division of labor strategies is an important aspect of the major transitions in evolution. As such, identifying specific evolutionary pressures that give rise to group-level division of labor has become a topic of major interest among biologists. To overcom...

Division of labor is a striking feature observed in honey bees and many other social insects. Division of labor has been claimed to benefit fitness. In honey bees, the adult work force may be viewed as divided between non-foraging hive bees that rear brood and maintain the nest, and foragers that collect food outside the nest. Honey bee brood pheromone is a larval pheromone that serves as an ex...

This article presents the results of a qualitative study of women who had filed complaints of domestic violence, situating gender relations in a broader context. The authors focus on the meaning ascribed to sexual coercion in violent relations, suggesting that conjugal sexual violence is related to the perverse effects of changes in the sexual division of labor and the aggravated double demands...

T paper examines the staffing, division of labor, and resulting profitability of primary care physician practices. Division of labor is viewed as a mechanism to increase the efficiency of production processes through specialization. At the same time, division of labor also introduces coordination cost as handoffs and communication needs increase. We attempt to empirically assess the net effect ...

Thomas Christiano claims that one of the fundamental challenges democracy is faced with is the appropriate division of epistemic labor between citizens and experts. In this article I try to present and analyze Christiano’s solution from the perspective of social epistemology while utilizing the concepts and tools provided by this discipline. Despite fundamentally agreeing with his position, I a...
