This article pursues two tasks. The first is to clarify the value and productivity of Williams’s Keywords: a vocabulary culture society (first edition 1976, second expanded 1983a) for project Cultural Studies. clarification helped, I argue, by reading it alongside Vološinov’s Marxism philosophy language (published in Russian 1929, translated into English 1973). related task speculative developm...

We study round-robin tournaments with either three or four symmetric players whose values of winning are common knowledge. In the round-robin tournament with three players there are three stages, each of which includes one match between two players. The player who wins in two matches wins the tournament. We characterize the sub-game perfect equilibrium and show that each player maximizes his ex...

We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...

In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de…nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...

A few results generalizing well-known classical model theory ones have been obtained in the framework of institutions these last two decades (e.g. Craig interpolation, ultraproduct, elementary diagrams). In this paper, we propose a generalized institutionindependent version of the Beth definability theorem.
