To reflect further on 20 years of the journal, we present a lexicographic and bibliometric study of all papers published in Public Understanding of Science (PUS). Lexicographical analysis of the vocabulary of 465 abstracts shows five classes of associated concepts in two periods, 1992–2001 and 2002–2010. The concern for public attitudes and mass media coverage remains on the card; while language has shifted from ‘public understanding’ to ‘public engagement’ and environmental concerns have waned then waxed. The bibliometric analysis traces the position of PUS in the inter-citation network of 165 related journals (ISI Web of Science citation database), grouped into 10 disciplines for the purpose of this analysis. Indicators derived from network logic show that the established position of PUS has been stable since 1997. PUS serves a varied brokerage role as gatekeeper into and liaison maker between disciplines. Its inter-citation network position allows PUS to perform inter-disciplinary boundary spanning work that offers a safe space for experimentation with ideas.

The Center for Medicare and Medicaid Services requires organizations to comply with the Patient Self-Determination Act by having processes that inform patients about their rights to execute an advance directive (AD) and engage in shared decision-making. The aim of this study was to compare AD data from a previous study (1999–2002) to a postenculturation (2011–2015) of a structured process for documented patient’s preferences. Second, to conduct a descriptive, bivariate analysis of the enculturated structured ADs process during 2011 and 2015. This descriptive, comparative analysis included 500 random patients from four hospitals, and the enculturated descriptive analysis included 302 patients from six hospitals. Comparisons showed less no ADs and a greater institutional ADs post compared with pre ( p
