  abstract = {The beta relaxation is a principal source of information about the
	dynamics in the glassy state; however, the nature of this process
	remains a controversial issue. In this paper, we show that properties
	of the beta relaxation measured below Tg are sensitive to the structure
	of the glass; that is, the thermodynamic path from the equilibrium
	liquid strongly affects the beta relaxation times, their distribution,
	and the activation energy quantifying their temperature dependence.
	These results support the idea that the Johari-Goldstein beta process
	is the precursor to the structural relaxation transpiring at longer
	times. We discuss the experimental findings in light of the heterogeneous
	and homogeneous scenarios for the beta process.},
