Contingency tables often arise from collecting patient data and from lab experiments. A typical question to be answered based on a contingency table is whether the rows or the columns show a significant difference. Median Polish (MP) is fast becoming a prefered way to analyse contingency tables based on a simple additive model. Often, the data need to be transformed before applying the MP algor...

We develop a uniform coalgebraic approach to J\'onsson-Tarski and Thomason type dualities for various classes of neighborhood frames algebras. In the first part paper we construct an endofunctor on category complete atomic Boolean algebras that is dual double powerset functor $\mathsf{Set}$. This allows us show duality can be viewed as algebra-coalgebra duality. generalize this any class presen...

Abstract There are two different modal logics: the logic T assuming contingency and K = logical determinism. In paper, I show that Aristotelian treatise On Interpretation (???? ?????????, De Interpretatione ) has introduced some modal-logical relationships which correspond to . this logic, it is supposed there contingent events. The N?g?rjunian ??vara-kart?tva-nir?k?ti?-vi??o?-ekakart?tva-nir?k...

Globalization, acute competition, the information technology revolution, and increasing customer sophistication are radically redefining environmental conditions, and, meanwhile, challenging managerial representations and traditional organizational recipes for managing intraand inter-firm relationships. Hence, we examine in this study the way companies interact with their employees and customer...

In §2 and §3 it is proved that there exists a one-one mapping between a minimal contingential logic extended with a suitable axiom for a propositional constant τ , namedK∆τw, and a logic of necessityKjτw whose language contains j and τ . The form of the proposed translation aims at giving a solution to a problem which was left open in a preceding paper. It §4 it is shown that the presence of τ ...

Modal logic is sometimes characterized as the logic of necessity and possibility, of “must be” and “may be”. The aim of this book is to present both semantical and syntactical features of the subject and to illustrate gy detailed analysis of the three most popular modal systems S5,S4 and K. The text presupposes some knowledge of classical logic, although the necessary information is briefly rec...
