He was a young man of twenty in the year that Origin of Species was published; he approached the end of his life just before Albert Einstein presented us with General Relativity. His lifetime saw the emergence of psychology as a discipline separate from ph...

Peirce ’ s i and Cohen ’ s κ for 2 × 2 Measures of Rater Reliability

This study examined a historical mixture model approach to the evaluation of ratings made in “gold standard” and two-rater 2 × 2 contingency tables. Peirce’s i and the derived i average were discussed in relation to a widely used index of reliability in the behavioral sciences, Cohen’s κ.

Sets play a key role in foundations of mathematics. Why? To what extent is it an accident of history? Imagine that you have a chance to talk to mathematicians from a far away planet. Would their mathematics be setbased? What are the alternatives to the set-theoretic foundation of mathematics? Besides, set theory seems to play a significant role in computer science, in particular in database the...

S-Arithmetic Khintchine-Type Theorem

In this article we prove a convergence S-arithmetic Khintchine-type theorem for product of non-degenerate ν-adic manifolds, where one of them is the Archimedian place.
