Taking time seriously
Transcript of Taking time seriously
in historical networks?
Claire Lemercier, CNRS
Center for the Sociology of Organizations Sciences Po, Paris
The historians' practice
People interested in dynamics
The sociological canon
Change, which change?
Type 1: do ties persist or not?
Type 2: does their content change?
Type 3: change in size of ego-networks
Type 4: change in attributes of alters
Are we talking about
Networks, i.e. structure
Thinking about interesting patterns
Thinking about dynamics
i.e. underlying mechanisms
From sociology: actor-oriented
From physics (et al.):
Choosing what/whom to follow
Think flows and riverbeds
do we need
specific research questions (
choices in data processing (
Feld, Suitor and Gartner Hoegh, 2007
White, Boorman, Breiger, 1976
6 local doc. students
1 left, 2 difft places,
2 difft relationships
Questions on institutionalization
“We must identify chunks of time that substantively capture
the nature of relational events and the character of temporary
networks that arise in the focal context”
vs. “largely artificial constructions built by aggregating
dead past events” (Moody/McFarland/Bender deMoll 2005)
& Whittington, 2012
Harries & Stevenson, 2012
Preferences in triads (homophily, reciprocation, transitivization, etc.)
-> Think anthropology!
Östborn & Gerding, work in progress (TCP Paris, 2014)
similar requirements (Bach, 2014)
The question of mental maps: what do we want
not to move
Back to questions about change
preliminary before Rosé, 2011
"What happens to the network of the largest companies listed at the Paris exchange
(companies sharing directors) between 1911 and 2000?"
-> following companies? change in directors, mergers, etc.
-> following "the largest listed companies"? overall structure, general mechanisms
-> what is a listed company, and what is a director to begin with?
Should slices overlap?
Interactions and relations / Traffic and backcloth (Atkin)
Ties do not live forever...
... or do they?
Düring, Bixler, Kronenwett & Stark, 2011
The remembrance of ties past:
tools (e.g. GraphDiaries) require
ties with a date of death (duration)
matters most, when ties point from older to younger: metaphorical family trees
Rosenthal, Fingrutd, Ethier,
Karant & McDonald, 1985
Eumann & März, 2012
Sigrist & Widmer, 2011
