# Slop University paper follows one number across the engineer's screen

> A paper led by the School of Emergent Priorities observes structural engineers reviewing earthquake analyses of tall buildings and records how they set the factor by which the displayed movement is exaggerated.

For fourteen weeks a doctoral candidate from the School of Emergent Priorities
sat beside structural engineers and wrote down a single number each time one of
them changed it. The number is the factor by which a tall building's computed
movement in an earthquake is enlarged so that it can be seen on a screen, and
the record is now a paper: _Turn It Up Until It Moves: How Structural Engineers
Set the Deformation Scale Factor When Reviewing Tall-Building Seismic Analyses_,
by Sunniva Balogun, Doctoral Candidate, Dr Vigdis Emenike, Senior Lecturer in
the School of Underlying Conditions, and Dr Lindiwe Achterberg, Lecturer.

> I was made very welcome in four offices and followed rather less of the

Across 61 working sessions and 23 engineers, the paper connects an everyday
display setting to the wider practice of professional looking. It reports that
the factor is set by eye and to suit the company, that experienced reviewers
push it to extremes in order to find what a gentler picture conceals, and that
of 212 figures in the offices' issued reports, 31 say what factor they were
drawn at.

The University counts the paper among the returns on its standing interest in
what its researchers notice while they are meant to be attending to something
else. Dr Emenike said the collaboration had shown that the two schools "keep
their curiosity in much the same drawer".
