An irrational-slope Thompson’s group

Emergence of group rationality from irrational individuals

Evolutionary theory predicts that animal decision makers should be rational, meaning that they consistently choose fitnessmaximizing options. Despite this, violations of rationality have been found repeatedly in humans and other animals. The significance of these violations remains controversial, but many explanations point to cognitive limitations that prevent animals from adequately processin...

SLOPE PROFILE MORPHOMETRY AS AN INDICATOR FOR SLOPE MOVEMENT

Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...

Predictors of Irrational Parenthood Cognitions in an Iranian Group of Infertile Women

OBJECTIVES The aim of this study was to investigate possible predictors of irrational parenthood cognitions among infertile women seeking treatment. METHODS In a cross-sectional study, 300 women who visited an Infertility Center in Iran during 2010 were studied. A pre-validated inventory was used to assess irrational parenthood cognitions. Potential predictors of the total irrational parentho...

An Irrational Construction of R from Z

This paper reports on a construction of the real numbers in the ProofPower implementation of the HOL logic. Since the original construction was implemented, some major improvements to the ideas have been discovered. The improvements involve some entertaining mathematics: it turns out that the Dedekind cuts provide many routes one can travel to get from the ring of integers, Z, to the field of r...
