‘NOTHING EITHER GREAT OR SMALL’

Nothing either good or bad but action makes it so.

Federico and Perez, in a recent issue of The Journal of Physiology, provide new insight into the impact of incomplete spinal cord injury (SCI) on corticospinal preparation for movement (Federico & Perez, 2017). In people with chronic incomplete cervical SCI and age-matched control subjects, they measured motor evoked potentials evoked by cortical (MEPs) or subcortical (CMEPs) stimulation and sh...

Take-all or nothing

Take-all disease of Poaceae is caused by Gaeumannomyces graminis (Magnaporthaceae). Four varieties are recognised in G. graminis based on ascospore size, hyphopodial morphology and host preference. The aim of the present study was to clarify boundaries among species and varieties in Gaeumannomyces by combining morphology and multi-locus phylogenetic analyses based on partial gene sequences of I...

All-or-Nothing Monitoring

A principal can observe both the output and input of an agent who works at a job involving multiple tasks. We provide a simple theory that explains why it may be optimal for the principal to use only output-based incentive contract, even though the principal can monitor the agent’s actions perfectly in all but one task and knows exactly which action is optimal for each task.

Hats: all or nothing

N distinguishable players are randomly fitted with a white or black hat, where the probabilities of getting a white or black hat may be different, but known and the same to all the players. All players guess simultaneously the color of their own hat observing only the hat colors of the other N − 1 players. The team wins if all players guess right. No communication of any sort is allowed, except...
