Base-rate neglect is a persistent phenomenon in which subjects do not place sufficient weight on the probabilities of occurrence of relevant events. Two experiments with college students support the hypothesis that base-rate neglect may be minimized by providing base-rate training in the absence of case, or witness, cues, prior to introducing (or reintroducing) these cues. In Experiment 1, the ...

Nous proposons dans cet article un nouveau modèle de base de données appelé base de données à base ontologique (BDBO) qui présente deux caractéristiques. D'une part, il permet de gérer à la fois des ontologies et des données. D'autres part, il permet d'associer à chaque donnée le concept ontologique qui en définit le sens. Les ontologies considérées sont celles qui peuvent s'exprimer sous forme...

As part of the recent developments in infinite matroid theory, there have been a number of conjectures about how standard theorems of finite matroid theory might extend to the infinite setting. These include base packing, base covering, and matroid intersection and union. We show that several of these conjectures are equivalent, so that each gives a perspective on the same central problem of in...

An understanding of why adenine (A) pairs with thymine (T) and cytosine (C) with guanine (G) in DNA is very useful in the design of sensors and other related devices. We report the use of dissociation energies, geometries and molecular electrostatic potentials (MEPs) to justify the canonical (AT and CG) Watson-Crick pairs. We also analyze all mismatches in both configurations-cis and trans-with...

A new system of hexadecimal and base-256 numerals is proposed whose digit shapes are based on binary numerals. The proposed numerals are implemented in open source fonts and integrated into popular editors (Notepad++ and Eclipse) to prove the concept.

In an earlier paper we introduced Lévy base correlation. In this paper we look at base expected loss at maturity both in the Gaussian copula and Lévy based models and link it to base correlation in these frameworks. We report on the existence of smile in both base correlation curves and discuss different interpolation methodologies in view of absence of arbitrage. Finally we discuss the propert...
