Large systems of logical equations are considered in this paper, each depending on a restricted number of variables. A method of reduction is suggested that reduces the number of roots in separate equations, which in its turn saves time spent for finding roots of the whole system. Three mechanisms of reduction are proposed, each looking for some prohibited combinations of variables in separate ...

This paper puts forward a normative framework for computational societies which enables the handling of incomplete knowledge about normative relations. In particular, attempts to perform a social action are evaluated as permitted, prohibited (i.e. not permitted) or pending for execution (i.e. neither permitted nor prohibited). This latter category of attempts can eventually be resolved as permi...

We tested this prediction among children (N = 50) who solved and explain...

The performance of 5,717 aviation security screeners in detecting prohibited items in x-ray images of passenger bags was analyzed over a period of 4 years. The measure used in this study was detection performance on the X-Ray Competency Assessment Test (X-Ray CAT) and performance on this measure was obtained on an annual basis. Between tests, screeners performed varying amounts of training in t...
