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
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

Theory of phonon-mediated relaxation in doped quantum dot molecules
A quantum dot molecule doped with a single electron in the presence of
diagonal and off-diagonal carrier-phonon couplings is studied by means of a
non-perturbative quantum kinetic theory. The interaction with acoustic phonons
by deformation potential and piezoelectric coupling is taken into account. We
show that the phonon-mediated relaxation is fast on a picosecond timescale and
is dominated by the usually neglected off-diagonal coupling to the lattice
degrees of freedom leading to phonon-assisted electron tunneling. We show that
in the parameter regime of current electrical and optical experiments, the
microscopic non-Markovian theory has to be employed.Comment: Final extended version, 5 pages, 4 figure
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
