An axiomatic characterization of a two-parameter extended relative entropy

The uniqueness theorem for a two-parameter extended relative entropy is proven. This result extends our previous one, the uniqueness theorem for a one-parameter extended relative entropy, to a two-parameter case. In addition, the properties of a two-parameter extended relative entropy are studied.Comment: 11 page

The paper obtains the general form of the cross-covariance function of vector fractional Brownian motion with correlated components having different self-similarity indices

Üzemi óvodák 1945 és 1975 között

A hazai óvodarendszer speciális eleme, a vállalati óvodák kialakulásának a története elsősorban a kisgyermekek nappali ellátásának jelenlegi kérdései és problémái miatt lehet számunkra fontos és tanulságos. Nemcsak a mindennapi diskurzusokban, de számos szakpolitikai megnyilvánulásban is a gyermeknevelés és a női munkavállalás összeegyeztetésében, a munkahelyi gyermekintézményekben látják az egyik lehetséges megoldást. A nyilatkozatokban hivatkozási alap, sőt sokszor követendő példa gyanánt a múlt rendszerben létező intézmények jelennek meg. Tanulmányomban arra keresem a választ, hogy vajon az államszocializmus ’45 és ’75 közötti időszakában hogyan épült ki és hogyan tartotta fenn magát ez a hálózat, mik voltak az erősségei/ gyengeségei, és legfőképpen hogyan ágyazódott bele a jóléti rendszer egészébe

Teaching rhetoric: A proposal to renew rhetorical education in Hungarian and Central European contexts

Rhetorical education faces significant challenges of the virtual knowledge society. Classroom teaching in skill-development still seems inevitable, however, the face-to-face experience has to gain more momentum and improve quality. It is especially important in Central European contexts where the history of teaching rhetoric has not been without fractures after World War II. The present paper is an approach that conceptualizes new aims of teaching rhetoric and suggests ways to reform the educational program of rhetoric at the secondary level. It sets of from the assumption that rhetoric should no longer be conceived and taught of as a toolkit to formulate texts, but rather as a behaviour and sensitivity to human affairs. Thus, rhetorical education should facilitate not so much the production of speeches but the birth of the rhetorical citizen. The education serving this aim does not the eliminate the classical roots of rhetorical literacy. On the contrary, it exploits the dynamic capacities of the two-millennia old faculty. The paper introduces a detailed, three-phased educational process with which rhetorical sensitivity can be bred in the classroom, while improving rhetoric as a subject matter itself

On the Orthogonal Stability of the Pexiderized Quadratic Equation

The Hyers--Ulam stability of the conditional quadratic functional equation of Pexider type f(x+y)+f(x-y)=2g(x)+2h(y), x\perp y is established where \perp is a symmetric orthogonality in the sense of Ratz and f is odd.Comment: 10 pages, Latex; Changed conten

Synthesizing judgements: a functional equations approach

AbstractWe discuss several conditions which are reasonable requirements for functions synthesizing either ratio or measure judgements (or both) and determine all synthesizing functions satisfying either shorter or longer lists of such assumptions (yielding more general or more specific synthesizing procedures, respectively)

Measurements and Information in Spin Foam Models

We present a problem relating measurements and information theory in spin foam models. In the three dimensional case of quantum gravity we can compute probabilities of spin network graphs and study the behaviour of the Shannon entropy associated to the corresponding information. We present a general definition, compute the Shannon entropy of some examples, and find some interesting inequalities.Comment: 15 pages, 3 figures. Improved versio
