Research concerning the topic of possible association of religiosity and substance use has already brought forth a significant amount of data, identifying strong belief in a religion as a protective factor in most cases. However, as in all other subject areas dealing with correlations between religion and health components, the issue of religiosity and substance (ab)use also produced some conflicting findings, hindering the formulation of a clear and stable consensus interpretation of this relationship. The aim of our examination was to provide empirical data for clarifying uncertainties about the possible effects of religiosity on substance use by examining a sample which is remarkable in Hungary: 1337 clinically diagnosed drug abuser patients and 205 normal controls. Based on our results we suggest some changes on the general approach of the effect of religiosity on substance use.

Reading Disorder (RD) belongs to Specific Learning Disorders within the chapter of Neurodevelopmental Disorders in the Diagnostic and Statistic Manual of Mental Disorders 5th edition. Previous research shows that the time of the diagnosis of RD – early (before starting school) or late – has a great impact on the prognosis. In the current paper we present the cases of two children diagnosed with RD. Our cases demonstrate that if RD is diagnosed in early childhood, the child’s and his/her family’s quality of life can be influenced in a positive direction, while late recognition of RD might influence the child’s and the family’s quality of life negatively. For these reasons it is important that experts recognize RD in time, start appropriate treatment and give proper support to children diagnosed with RD and their families. © 2015, Hungarian Association of Psychopharmacology.

Utilizing a recently found class of exact, analytic rotating solutions of nonrelativistic fireball hydrodynamics, we calculate analytically the single-particle spectra, the elliptic flows, and two-particle Bose-Einstein correlation functions for rotating and expanding fireballs with spheroidal symmetry. We demonstrate that rotation generates final state momentum anisotropies even for a spatially symmetric, spherical initial geometry of the fireball. The mass dependence of the effective temperatures as well as the Hanbury Brown-Twiss (HBT) radius parameters and the elliptic flow are shown to be sensitive not only to radial flow effects but also to the magnitude of the initial angular momentum. © 2016 American Physical Society.

When we construct continuous and/or discrete mathematical models in order to describe a real-life problem, these models should possess various qualitative properties, which typically arise from some basic principles of the modelled phenomenon. In this paper we investigate this question for the numerical solution of initial-boundary value problems for parabolic equations with nonzero convection and reaction terms with function coefficients in higher dimensions. The Dirichlet boundary condition will be imposed, and we will solve the problem by using linear finite elements and the θ-method. The principally important qualitative properties for this problem are the non-negativity preservation and different maximum principles. We give the conditions for the geometry of the mesh and for the choice of the discretization parameters, i.e., for θ and the time-step sizes, under which these discrete qualitative properties hold. Finally, we give numerical examples to investigate how sharp our conditions are. © 2010 Springer-Verlag Berlin Heidelberg.

The paper aims to summarize the Easter-time customs from the point of view of its "festivity". This cycle of feasts is organized into several "sequences". For the days before Easter it is typical to follow the pattern (given by Arnold Van Gennep): "rites of passage", i.e. pre-liminal, liminal and post-liminal sequences. Within the singular customs there are several strata of human activity. During the whole of Easter time the everyday activity remains continuous, and it is characterized by its direct connection with the feast. During the Easter holidays proper, dramatic performances dominate. Lamenting Christ and celebrating the resurrection happen within the framework of folk theatre. Easter-one of the most important feasts in the festive year-is expressed on several strata: human activity, food, dress, acoustic and kinetic codes prevail, and visual and textural codes dominate as well. The analytic method, suggested in the paper might serve also the comparative European analysis of the ritual year. © 2014 Akadémiai Kiadó, Budapest.
