Tradition as a Communication System. A Pragmatic Approach

A context of my paper is the debate on reason, tradition and traditional communities, in which this moral and epistemological issues were discussed as a part of general socio-philosophical theory of modernity. In particular I intend to locate my considerations in the context of formal-pragmatic theory of modern communicative rationality developed by Jürgen Habermas and Robert Brandom. I will provide a competitive model of the rationality of tradition by applying a conceptual toolkit of pragmatically oriented analysis to explain practices connected with vocabulary of tradition. I argue that tradition as a communication system has a fully rational structure. My main claim is that communicative structure of tradition has a rational structure of language game. This structure includes defined principles of communication for members of closed tradition-grounded community and rule of inclusion for potential new members. Firstly I consider closely internal principles of communication within the framework of tradition contrasting them shortly with normative-deontic rules of the postenlightenment idea of pragmatic communication discussed by Jürgen Habermas and Robert Brandom. After that I examine the rule of inclusion — the rule, which mediates between closed system of tradition-based community and his environment.Numer został przygotowany przy wsparciu Ministerstwa Nauki i Szkolnictwa Wyższego

Classical linear vector optimization duality revisited

With this note we bring again into attention a vector dual problem neglected by the contributions who have recently announced the successful healing of the trouble encountered by the classical duals to the classical linear vector optimization problem. This vector dual problem has, different to the mentioned works which are of set-valued nature, a vector objective function. Weak, strong and converse duality for this "new-old" vector dual problem are proven and we also investigate its connections to other vector duals considered in the same framework in the literature. We also show that the efficient solutions of the classical linear vector optimization problem coincide with its properly efficient solutions (in any sense) when the image space is partially ordered by a nontrivial pointed closed convex cone, too.Comment: 10 page

Wokół świętości. Rozważania kulturoznawcze

The development of the concept of holiness is associated with the cultural process of separating the practical activity and the primary magical beliefs, termed by Max Weber's the ‘disenchantment of the world’. As a result, the sphere of human activity was divided into the sacred and the profane. Holiness was generally associated with the operation of variously recognised supernatural factors. In the Judeo-Christian tradition, it is an attribute of God's holiness. As a generalisation of all the virtues, it is endowed with the ethical dimension. The moral dimension of holiness and the specific rules of behaviour towards the sacred are reflected in everyday language,several sayings and proverbs

Embeddings of the black holes in a flat space

We study the explicit embeddings of static black holes. We obtain two new minimal embeddings of the Schwarzchild-de Sitter metric which smoothly cover both horizons of this metric. The lines of time for these embeddings are more complicated than hyperbolas. Also we shortly discuss the possibility of using non-hyperbolic embeddings for calculation of the black hole Hawking temperature in the Deser and Levin approach.Comment: LaTeX, 7 pages.

Phonon-assisted decoherence and tunneling in quantum dot molecules

We study the influence of the phonon environment on the electron dynamics in a doped quantum dot molecule. A non-perturbative quantum kinetic theory based on correlation expansion is used in order to describe both diagonal and off-diagonal electron-phonon couplings representing real and virtual processes with relevant acoustic phonons. We show that the relaxation is dominated by phonon-assisted electron tunneling between constituent quantum dots and occurs on a picosecond time scale. The dependence of the time evolution of the quantum dot occupation probabilities on the energy mismatch between the quantum dots is studied in detail.Comment: 4 pages, 2 figures, conference proceeding NOEKS10, to be published in Phys.

Nonlinear translational symmetric equilibria relevant to the L-H transition

Nonlinear z-independent solutions to a generalized Grad-Shafranov equation (GSE) with up to quartic flux terms in the free functions and incompressible plasma flow non parallel to the magnetic field are constructed quasi-analytically. Through an ansatz the GSE is transformed to a set of three ordinary differential equations and a constraint for three functions of the coordinate x, in cartesian coordinates (x,y), which then are solved numerically. Equilibrium configurations for certain values of the integration constants are displayed. Examination of their characteristics in connection with the impact of nonlinearity and sheared flow indicates that these equilibria are consistent with the L-H transition phenomenology. For flows parallel to the magnetic field one equilibrium corresponding to the H-state is potentially stable in the sense that a sufficient condition for linear stability is satisfied in an appreciable part of the plasma while another solution corresponding to the L-state does not satisfy the condition. The results indicate that the sheared flow in conjunction with the equilibrium nonlinearity play a stabilizing role.Comment: 26 pages, 16 figure
