    © 2016, UNESCO IBE.Using comparative data, this article examines the level and distribution of participation in adult education opportunities among countries that participated in PIAAC. It considers observed cross-country patterns in relation to some mechanisms that drive unequal chances to participate and to some policy issues that surround the provision, governance, and financing of different types of adult learning. It also explores recent policy developments relevant to AE in three selected …Read more

    We present a measurement of the rate of distant Type la supernovae derived using four large subsets of data from the Supernova Cosmology Project. Within this fiducial sample, which surveyed about 12 deg2, 38 supernovae were detected at redshifts 0.25-0.85. In a spatially flat cosmological model consistent with the results obtained by the Supernova Cosmology Project, we derive a rest-frame Type la supernova rate at a mean redshift z ≃ 0.55 of 1.53-0.25-0.31-0.28-0.32 × 10-4 h 3 Mpc-3 yr-1 or 0.58…Read more
