Social scientists are producing an ever-expanding volume of data, leading to questions about appraisal and selection of content given finite resources to process data for reuse. We analyze users' search activity in an established social science data repository to better understand demand for data and more effectively guide collection development. By applying a data-driven approach, we aim to ensure curation resources are applied to make the most valuable data findable, understandable, accessible, and usable. We analyze data from a domain repository for the social sciences that includes over 500,000 annual searches in 2014 and 2015 to better understand trends in user search behavior. Using a newly created search-to-study ratio technique, we identified gaps in the domain data repository's holdings and leveraged this analysis to inform our collection and curation practices and policies. The evaluative technique we propose in this paper will serve as a baseline for future studies looking at trends in user demand over time at the domain data repository being studied with broader implications for other data repositories.

Using data from the National Longitudinal Survey of Youth, this article examined how early maternal characteristics, an adolescent's family environment, and the adolescent's own attitudes and behaviors were associated with the odds of a nonmarital teenage birth among youth born to teenage mothers. Multivariate analyses indicated that these domains were closely linked. Early maternal characteristics shaped the later family environment of adolescents (parenting quality and home environment), which, in turn, was associated with the attitudes and behaviors of teens that put them at risk of a nonmarital birth. Notably, there was variation in some of the associations by gender. Increased mother's cognitive ability lowered the risk of a nonmarital birth for boys, but not for girls, whereas fertility expectations were significant for girls, but not for boys. There were no race-ethnic differences in the risk of a teenage birth among girls, although Black boys had a higher risk than White boys., Competing Interests: Declaration of Conflicting Interests The author(s) declared no potential conflicts of interest with respect to the authorship and/or publication of this article.

Can the decline in autopsy rates be reversed by solving logistical problems that impede or deter permissions and arrangements? The authors report an increase in the autopsy rate at their institution after a Decedent Affairs Office was established. Furthermore, the time between death and autopsy has been greatly narrowed, thus providing optimal tissue for diagnosis. As an additional benefit, the number of organ donations has also risen.
