Oliver's 1997 four-stage loyalty model proposes that loyalty consists of belief, affect, intention, and action. Although this loyalty model has recently been subject to empirical examination, the issue of moderator variables has been largely neglected. This article fills that void by analyzing...

Magnetoelectric susceptibility (ξ) of classical magnetoelectrics is always substantially smaller that the geometric average of the electric (χ <Subscript> e </Subscript>) and magnetic (χ <Subscript> m </Subscript>) susceptibilities. Materials reaching the equality ξ <Superscript>2</Superscript>=χ <Subscript> e </Subscript> χ <Subscript> m </Subscript> as a limiting value may thus be considered as ideal...</subscript></subscript></superscript></subscript></subscript>

Different measures to reduce the space heating consumption can contribute to a more rational use of energy. Such measures are for example the use of solar collectors and the application of the principle of cogeneration by block-type thermal power stations (BTP) with internal combustion engines....
