Narrow Results

We consider all possible scalar bilinears, which couple to two fermions of the standard model. The various baryon and lepton number violating couplings allowed by these exotic scalars are studied. We then discuss which are constrained by limits on proton decay (to a lepton and a meson as well as to three leptons), neutron–antineutron oscillations, and neutrinoless double beta decay.

A new dimension of analysis in human reliability models, operator analysis, and its possible mathematical quantification is hereby presented and discussed. Derived from psychometric studies, operator analysis is based on human abilities theory, and facilitates the quantification of the parameters required for a quantitative analysis of human reliability while also reducing the subjectivity in the analysis. Herein, the inclusion of cognitive, social and interpersonal skills puts focus on interpersonal differences and their impact on human performance. The innovative inclusion of Cattell-Horn-Carroll theory on cognitive abilities and Fleishman’s premises on social and interpersonal skills simultaneously addresses several problems of existing human reliability models. Furthermore, it provides a theoretical basis for causal cognitive models of human error with a strong experimental support specifying their interrelationships and dependencies.
