  abstract = {Dielectric measurements on 4,4'-methylenebis(N,N-diglycidylaniline)
	were carried out over a temperature range from 258 to 335 K, at
	hydrostatic pressures from ambient to 300 MPa. Both the shape of
	the alpha-relaxation function and the Tg-normalized temperature
	dependence of the relaxation times (fragility) were found to be
	independent of pressure, consistent with the established correlation
	between these two quantities. Interpretation of the data using an
	extension of the model of Adam and Gibbs yielded values for the
	configurational entropy and the excess heat capacity. The implication
	of this analysis is that these two quantities govern to a substantial
	extent both the temperature- and pressure-dependences of the structural
	relaxation times. We also show that all relaxation times can be
	rescaled onto a single master curve, whose abscissa is simply related
	to the ratio between the configurational entropy and the excess
	heat capacity.},
