Two wrongs don't make a right: the initial viability of different assessment rules in the evolution of indirect reciprocity.

Two Wrongs Do Not Make a Right: Flaws in Alternatives to Fee-for-Service Payment Plans Do Not Mean Fee-for-Service Is a Good Solution to Rising Prices; Comment on “Fee-for-Service Payment - An Evil Practice That Must Be Stamped Out?”

Professor Naoki Ikegami’s “Fee-for-service payment – an evil practice that must be stamped out” summarizes many of the failings of alternatives to fee-for-service (FFS) payment systems. His article also offers several suggestions for improving FFS systems. However, even powerful arguments against many of the alternatives to FFS, does not make a convincing argument for FFS systems. In addition, ...

Effect of assessment error and private information on stern-judging in indirect reciprocity

Stern-judging is one of the best-known assessment rules in indirect reciprocity. Indirect reciprocity is a fundamental mechanism for the evolution of cooperation. It relies on mutual monitoring and assessments, i.e., individuals judge, following their own assessment rules, whether other individuals are “good” or “bad” according to information on their past behaviors. Among many assessment rules...

Non-linear stochastic inversion of 2D gravity data using evolution strategy (ES)

In the current work, a 2D non-linear inverse problem of gravity data is solved using the evolution strategies (ES) to find the thickness of a sedimentary layer in a deep-water situation where a thick sedimentary layer usually exists. Such problems are widely encountered in the early stages of petroleum explorations where potential field data are used to find an initial estimate of the basin geo...

Advanced and upper-intermediate EFL learners’ reciprocity to mediation: A dynamic listening assessment

The present study aimed to capture and represent the mediator-learner’s interaction in the development of listening proficiency and statistically compare this interaction between high and low proficient English as a foreign language (EFL) learners. Thirty EFL learners participated in Oxford Quick Placemat Test (OQPT) and the Interactions/Mosaic Listening Placement (IMLP) Test to select those wh...
