    Notes: Abstract The paper argues that the human-centred approach should be considered as an alternative to the techno-economic model of the EC information society. This alternative approach should be based on the principles of democratic participation of citizens and social cohesion. Using a community development based approach the paper introduces concepts of partnership, tripartite collaboration and universal participation. Having evaluated a human-centred approach to the information society this is then applied to the results of four case studies of Danish and Swedish community teleservice centres (CTSCs), and the subsequent lessons drawn.

    Notes: Abstract In experimental sciences, random processes often place a fundamental limit on the achievable measurement resolution. A well known example is the Johnson noise voltage across a resistor. In this paper, we describe observations of the spontaneous transfer of heat in two equilibrium systems: one consisting of a thermometer linked to a reservoir, the other consisting of two thermometers connected to each other and linked to a reservoir for the purpose of temperature stabilization. In the second system, we find anti-correlations between the temperature fluctuations of the two thermometers at intermediate frequencies. We also find that the low frequency temperature noise density of the thermometers, in units of $$K/\sqrt {Hz} $$ , is given by $$\sqrt {4Rk_B T^2 } $$ , whereR is the thermal resistance of the link between the thermometer and the reservoir. This implies that for noise reduction purposes,R is the only available engineering parameter to adjust. In a recent thermometer design, we have reduced R to achieve a low frequency temperature noise density of 5×10−11 $$K/\sqrt {Hz} $$ at 2.18 K.

    Notes: Elektronenspektren von Komplexen sind besonders aussagekräftig, wenn sie an Kristallen bei tiefer Temperatur oder variierter Temperatur mit polarisiertem Licht vermessen werden. Diese nicht sehr aufwendige Arbeitsweise ermöglicht es, viele der gemessenen Banden sicher zuzuordnen; anhand dieser Zuordnungen, deren Gültigkeit nicht von den Annahmen irgendeines theoretischen Modells abhängt, können Theorien der Elektronenstruktur überprüft werden.

    Notes: The electronic spectra of complexes are especially informative if they are recorded for crystals at low temperature or at varying temperature with polarized light. This straightforward technique frequently permits reliable band assignment. Such assignments, being independent of the assumptions of any particular theoretical model, then provide a basis for testing theories of electronic structure.
