Optimal reproductive-skew models fail to predict aggression in wasps.
Optimal-skew models (OSMs) predict that cooperative breeding occurs as a result of dominants conceding reproductive benefits to subordinates, and that division of reproduction within groups reflects each cooperator's willingness and ability to contest aggressively for dominance. Polistine paper wasps are a leading model system for testing OSMs, and data on reproduction and aggression appear to ...
متن کاملHow to Make the Quantum Adiabatic Algorithm Fail
The quantum adiabatic algorithm is a Hamiltonian based quantum algorithm designed to find the minimum of a classical cost function whose domain has size N . We show that poor choices for the Hamiltonian can guarantee that the algorithm will not find the minimum if the run time grows more slowly than √ N . These poor choices are nonlocal and wash out any structure in the cost function to be mini...
متن کاملTransactional skew and assured fitness return models fail to predict patterns of cooperation in wasps.
Cooperative breeders often exhibit reproductive skew, where dominant individuals reproduce more than subordinates. Two approaches derived from Hamilton's inclusive fitness model predict when subordinate behavior is favored over living solitarily. The assured fitness return (AFR) model predicts that subordinates help when they are highly likely to gain immediate indirect fitness. Transactional s...
متن کاملA Simulation-Optimization Model For Capacity Coordination In Make To Stock/Make To Order Production Environments
Capacity coordination, as the tactical level of hierarchical production planning in hybrid MTS/MTO systems, includes numerous important decisions. In this paper, two of these decisions i.e. finding the best strategy for the acceptance/rejection of incoming orders and determining orders’ due dates – are investigated. Also a simulation model is proposed to evaluate the efficiency of the presented...
متن کاملCOProduction as Last Resort to Make IT Projects Less Doomed to Fail
In this position paper, we make the point that the tenets of the cultures of participation and co-production, if taken seriously, can reform IT development in organizations for the better.
