Newspaper Metadata Manual

This document describes the process that the University of North Texas (UNT) Libraries' Digital Newspaper Unit (DNU) uses to create metadata for the scanned newspapers published on The Portal to Texas History as part of the Texas Digital Newspaper Program (TDNP). High quality metadata helps users find what they want more quickly. Over time, accurate descriptive metadata fosters trust among the Portal's user community

Automated NDNP Quality Review

Presentation for the 2013 National Digital Newspaper Program (NDNP) Awardee Conference in Washington D.C. This presentation discusses automated processes and ensuring quality for the NDNP at the University of North Texas (UNT) Libraries

Extragalactic Constraints on the Initial Mass Function

The local stellar mass density is observed to be significantly lower than the value obtained from integrating the cosmic star formation history (SFH), assuming that all the stars formed with a Salpeter initial mass function (IMF). Even other favoured IMFs, more successful in reconciling the observed $z=0$ stellar mass density with that inferred from the SFH, have difficulties in reproducing the stellar mass density observed at higher redshift. In this study we investigate to what extent this discrepancy can be alleviated for any universal power-law IMF. We find that an IMF with a high-mass slope shallower (2.15) than the Salpeter slope (2.35) reconciles the observed stellar mass density with the cosmic star formation history, but only at low redshifts. At higher redshifts $z>0.5$ we find that observed stellar mass densities are systematically lower than predicted from the cosmic star formation history, for any universal power-law IMF.Comment: 6 pages, 5 figures, accepted to MNRA
