Consequently, the proportion of cooperation with cooperators in the beginning of the second session (M = 72.9%±3.2 CI) was at the level of the tenth repetition in the first session (M = 71.0%±4.3 CI; Figure 3).
Moreover, participants benefited from their experience with and improved knowledge of the partner types, indicated by a comparable proportion of cooperation with cooperators in the beginning of the second session as in the end of the first session (Figure 3).
The average group exhibited 0% cooperation when there were 3 cooperators in the last round, in condition I. Interestingly, each of the cooperation rates following rounds with 0, 2 and 4 cooperators was significantly higher than the cooperation following trials in which 3 players cooperated (0: U = 42.000, p<0.05; 2: U = 24.000, p<0.05; 4: U = 3.000, p<0.05, respectively).
Clearly, with less costly cooperation, occasional futile cooperation attempts (when the number of cooperators in a neighbourhood is less than the quorum) are less deleterious.
This leads to a scenario of both cooperation and conflict, whereby cancer cells are regarded as cooperators in terms of the disease, but create conflict (i.e. behave as cheats) in the eyes of the host.
Increasing diffusion gradually reduces the likelihood of maintaining three cooperators in a neighbourhood, resulting in a lower level of cooperation in the population.
We recalculated the cooperation rate in each sub-case according to the number of cooperators in the preceding trial (0 to 4); this excludes the decisions of the corresponding participant.
Firstly, the shape of the trade-off between the cost and benefit of cooperation has a profound effect on the success of cross-feeders (cooperators) in comparison to non cross-feeders (cheats).
But the request highlights the risks and complications — for prosecutors and cooperators — in long-running investigations in which both sides depend so greatly on each other.
But he sat in the witness box over two days this week, testifying dutifully as one of the government's key cooperators in the case.
The New Yorker, May 23 , 1994P. 46 ANNALS OF LAW about Northern District US Attorney Bill Hogan, 42, and his prosecution of the El Rukn drug-dealing gang, which fell apart after jailing many criminals because of allegations of impropriety between criminal cooperators in the case and their government handlers.
