So what are practices?
a temporally unfolding and
spatially
dispersed nexus of doings and
sayings
Schatzki, 1996
‘habits’, ‘bodily and mental routines’
‘permanent dispositions’
Reckwitz, 2002;
Entities
Performance
habituation, routine, practical
consciousness,
tacit knowledge, tradition
Performance often neither fully
conscious
nor reflective
Warde, 2005
Why people don’t do
what they ‘should’ - Jim Skea, 2011
Embodied habits & competencies (skills),
Meanings/ conventions (image)
Material artefacts (stuff)
Shove & Pantzar, 2005

Can we observe them?
(an empiricist’s
response)

“The recurrent enactment of specific
practices leaves all sorts of “marks” –
diet shows up in statistics on obesity;
heating and cooling practices have effect
on energy demand, and habits of laundry
matter for water consumption.
Identifying relevant “proxies” represents
one way to go.”
ESRC Sustainable Practices Working
Group (SPRG) Discussion Paper, 2011

§ Tried:
• Shadowing/tracking/observation
– Small n, can ask why, investigator effects (?)
– Historical?
• Time use surveys (diaries, e.g. UK ONS 2000, MTUS)
– Big n, non response issues, can’t ask why, complex data
– Rarely longitudinal, sometimes historical (MTUS)
§ Relatively Untried:
• Expenditure Surveys
– Big n, proxies for practices, can’t ask why, complex data
– e.g. http://link.springer.com/article/10.1007/s11269-012-0117-y
• TechnoTraces (Savage & Burrows, 2007; 2009; 2014)
– Transactions/meters/bills, proxies for practices, complex data, difficult to
process
How to detect ‘marks’ & proxies?

TechnoTraces: Practice Hunting
§ Inspiration:
– Qualitative study of telephone calling
– Lacohee & Anderson (2000) Interacting with the telephone, doi:10.1006/ijhcs.
2000.0439
§ Call types
– Duty calls: generally to family members and were made because the caller felt a
sense of duty to keep in touch
– Maintenance calls: real motivation was to maintain a friendship
– Grapevine calls: a series of calls often prompted by a call e.g. passing on news
– Batch calls: making a series of outgoing calls e.g. cheap rate, bored or lonely
§ Question: can we identify them in a call records dataset?
– c. 1.5 million incoming/outgoing phone call records (time, duration) linked to
surveys of c 1000 GB households 1999-2001

TechnoTraces: Practice Hunting
§ Algorithm:
– Sequence identifier
– Flexible ‘gap’ parameter
§ Batch calls (Out, Out, Out…)
– 20:00 -> late
– Not Thursdays or Fridays
– Sunday evenings
§ Grapevine calls (In, Out, Out…)
– 18:00 – 19:30
– Sunday evenings

‘Big’ Data Challenges
§ Provenance:
– Who did what to ‘my’ data?
§ Quality:
– It’s never clean
§ Samples
– What (or who) does it represent?
§ Sampling
– Do we really need it all?
§ Linkage
– Multiple methods & multiple views
19
It might be big but
is it clever?
Are people the only
agents?
And the bigger it is
the harder to clean
What & why?
