TL;DR: There are age differences in all verbal span tasks; the data support the conclusion that working memory span is more age sensitive than short-term memory span; and there is a linear relationship between span of younger adults and span of older adults.
Abstract: Using Brinley plots, this meta-analysis provides a quantitative examination of age differences in eight verbal span tasks. The main conclusions are these: (a) there are age differences in all verbal span tasks; (b) the data support the conclusion that working memory span is more age sensitive than short-term memory span; and (c) there is a linear relationship between span of younger adults and span of older adults. A linear model indicates the presence of three distinct functions, in increasing order of size of age effects: simple storage span; backward digit span; and working memory span.

TL;DR: The results suggest that span is influenced by interference, that age differences in span may be due to Differences in the ability to overcome interference rather than to differences in capacity, and that interference plays an important role in the relation between span and other tasks.
Abstract: The authors investigated the possibility that working memory span tasks are influenced by interference and that interference contributes to the correlation between span and other measures. Younger and older adults received the span task either in the standard format or one designed to reduce the impact of interference with no impact on capacity demands. Participants then read and recalled a short prose passage. Reducing the amount of interference in the span task raised span scores, replicating previous results (C. P. May, L. Hasher, & M. J. Kane, 1999). The same interference-reducing manipulations that raised span substantially altered the relation between span and prose recall. These results suggest that span is influenced by interference, that age differences in span may be due to differences in the ability to overcome interference rather than to differences in capacity, and that interference plays an important role in the relation between span and other tasks.

TL;DR: The London Millennium Footbridge experienced pedestrian-induced lateral vibration at its opening on June 10, 2000 and was closed on June 12, 2000, pending an investigation into the cause of the unexpected lateral movements as mentioned in this paper.
Abstract: The London Millennium Footbridge is located across the Thames River in Central London. At its opening on June 10, 2000, the bridge experienced pedestrian-induced lateral vibration. Observations on the day of opening and studies of video footage revealed up to 50 mm of lateral movement of the south span and 70 mm of the center span. The north span did not move substantially. The bridge was closed on June 12, 2000, pending an investigation into the cause of the unexpected lateral movements. This paper highlights the phenomenon of pedestrian-induced lateral vibration on footbridges and the current state of knowledge of the lateral loading effect. Modification of the bridge, introducing extensive passive damping, is currently underway with completion scheduled for the end of 2001.
