Pull or Push? Octopuses Solve a Puzzle Problem
Octopuses have large brains and exhibit complex behaviors, but relatively little is known about their cognitive abilities. Here we present data from a five-level learning and problem-solving experiment. Seven octopuses (Octopus vulgaris) were first trained to open an L shaped container to retrieve food (level 0). After learning the initial task all animals followed the same experimental protoco...
متن کاملPush or Pull? Grants, Prizes and Information
In the funding of R&D, push mechanisms, such as research grants, subsidize research input, while pull mechanisms, such as innovation prizes, reward research output. By rewarding research output, pull mechanisms create strong incentives for researchers to devote non observable inputs to R&D. Push mechanisms, in contrast, may reward a researcher independently of her output. In the presence of mor...

متن کاملA push-pull queueing system
We consider a two node multiclass queueing network given by two machines each with two classes. There are two streams of jobs: One stream originates in machine 1, which feeds it for further processing to machine 2, and the other stream moves in the opposite direction. We describe a policy for this system which is stable and which keeps both machines busy at all times. We obtain explicit express...
متن کاملPush and Pull Systems
Data broadcasting has emerged as an efficient way for the dissemination of information over asymmetric wireless environments where the needs of the various users of the data items are usually overlapping. In such environments, data broadcasting stands to be an efficient solution since the broadcast of a single information item is likely to satisfy a possibly large number of users. Communication...
