Anne Fausto - Sterling Frameworks of desire

search of newspaper stories covering scienti1⁄2c research on homosexuality shows that the popular press has settled on this analytic framework to explain homosexuality: either genes cause homosexuality, or homosexuals choose their lifestyle.1 The mischief that follows such a formulation is broad-based and more than a little pernicious. Religious fundamentalists and gay activists alike use the g...

Characterisations of Nelson Algebras

Nelson algebras arise naturally in algebraic logic as the algebraic models of Nelson’s constructive logic with strong negation. This note gives two characterisations of the variety of Nelson algebras up to term equivalence, together with a characterisation of the finite Nelson algebras up to polynomial equivalence. The results answer a question of Blok and Pigozzi and clarify some earlier work ...

Nelson–Aalen Estimator

The Nelson–Aalen estimator is a nonparametric estimator which may be used to estimate the cumulative hazard rate function from censored survival data (see Survival Distributions and Their Characteristics). Since no distributional assumptions are needed, one important use of the estimator is to check graphically the fit of parametric models, and this is the reason why it was originally introduce...
