Resolvent estimates for elliptic quadratic differential operators

2011

Sharp resolvent bounds for non-selfadjoint semiclassical elliptic quadratic differential operators are established, in the interior of the range of the associated quadratic symbol.

IMPLEMENTATION OF A QUALITY MANAGEMENT SYSTEM IN A TRAVEL AGENCY

2014

The present research refers to the major problems existing in the Romanian tourism, namely, "manufacturing" and commercialization of certain products non-compliant with the user’s requirements in terms of quality. In tourism and hospitality industry, quality can be judged on the extent to which the service received meets the customer’s expectations. So, the quality is important for both customers and managers of various travel agencies, as it can contribute to making better products at lower costs. Based on theoretical approaches on quality management of tourist services, this paper aims to analyze the activity of the largest travel agency in Romania - Happy Tour and assess the possibilitie…

The Equationally-Defined Commutator in Quasivarieties Generated by Two-Element Algebras

2018

The notion of the equationally-defined commutator was introduced and thoroughly investigated in (Czelakowski, 2015). In this work the properties of the equationally-defined commutator in quasivarieties generated by two-element algebras are examined. It is proved: If a quasivariety Q is generated by a finite set of two-element algebras, then the equationally-defined commutator of Q is additive (Theorem 3.1) Moreover it satisfies the associativity law (Theorem 3.6). The second result is strengthened if the quasivariety is generated by a single two-element algebra 2: If Q = SP(2), then the equationally-defined commutator of Q universally validates one of the following laws: [x,y] = x^y or [x,y…

On probabilistic interpretations of predicates

2016

In classical logic, any m-ary predicate is interpreted as an m-argument two-valued relation defined on a non-empty universe. In probability theory, m-ary predicates are interpreted as probability measures on the mth power of a probability space. m-ary probabilistic predicates are equivalently semantically characterized as m-dimensional cumulative distribution functions defined on Rm. The paper is mainly concerned with probabilistic interpretations of unary predicates in the algebra of cumulative distribution functions defined on R. This algebra, enriched with two constants, forms a bounded De Morgan algebra. Two logical systems based on the algebra of cumulative distributions are defined an…

I dove e le scene: una lettura geografica delle rappresentazioni spaziali negli allestimenti operistici

2020

Places and scenes: a geographical reading of spatial representations in opera productions The contribution moves from geographical interests and aims focusing on the representation of space in the scenic installations of opera. The melodrama represents an artistic expression that signifies the Western cultural dimension starting at least from the late Sixteenth century. Finding syntheses among music, words and drama, opera continues today to draw nourishment from its reproduction and re-proposal in scenic solutions, directorial visions and new productions. Through the critical comparison between pairs of alternative sets of three works that characterise the Italian musical production -Lucia…

The 1946 Production of The Fairy Queen in Covent Garden: 'A Triumph of British Music and Stagecraft'?

2006

This article examines the sets designed by John Piper for eight of Benjamin Britten's operas in the context of England's artistic and political post-war reconstruction. Piper created backdrops that found their logical conclusion in his stained-glass windows. They provide a sense of continuity whilst reflecting fundamental contradictions.

Współpraca i partnerstwo : teoretyczne modele relacji organizacji pozarządowych z jednostkami administracji publicznej

Analysis of multiple intelligences and creativity in university students

2018

espanolResumen: Un reto de la educacion actual es formar a alumnos competentes para desenvolverse en una sociedad diversa y dinamica. El cociente intelectual no es suficiente para garantizar el exito academico ni profesional (Extremera & Fernandez-Berrocal, 2006) y deben considerarse aspectos cognitivos, sociales y emocionales. El objetivo del estudio fue analizar el grado alcanzado en estudiantes universitarios de trabajo social en las inteligencias multiples, inteligencia emocional, creatividad y rendimiento academico, asi como su relacion y las diferencias en funcion del sexo y el curso en una muestra de 100 estudiantes. Se encontraron diferencias significativas en funcion del curso y re…
