Citing vs Cited Half-Life Asymmetry
A journal has two half-lives, and comparing them reveals its temporal personality. The cited half-life measures the median age of the articles the journal is cited for, capturing how long its own work stays useful. The citing half-life measures the median age of the references the journal's articles make, capturing how far back its authors reach. Burton and Kebler's 1960 half-life framework supplies the median-age machinery for both, and Ronald Rousseau's work on the temporal structure of journal citations underscores that incoming and outgoing citation streams age differently. When the two half-lives diverge, the asymmetry is informative: a journal whose work is cited for many years but which itself cites only recent literature sits at a fast research front yet produces durable results, while the reverse profile marks a synthesizing or archival journal. The asymmetry is the gap between how a journal is used and how it uses the literature.
