Representing change over time in the structure
and membership of social networks
|
- Hullo list members
I have been (intermitently) trying
develop was of representing development aid inteventions (plans and reality) in
social network terms - both at the level of inter-connected institutions and
inter-connected people. One aspects of development plans is their view of the
future as trajectory or sequence of desired changes. The traditional method of
representing development aid plans has used a device called the "Logical
Framework" . This matrix prioritises / emphasises the temporal dimension, of
one activity leading to another,... leading to another... In the process it
neglects what could be called the ecological dimension, how the various
activities, or preferably actors, are connected to each other at each point in
time. Network diagrams seem to require by necessity at least two dimensions to
represent them. I would like to hear from list members how temporal changes in
network structure and membership have been represented visually, in any way at
all - in the broadly defined field of social network analysis. I am hoping to
be able to learn from past efforts.

- Hi Rick,
If I understand well what you're interested in
doing, it may not be too far from the recent work of Butts & Pixley on a
graph-theoretic (structural) model of event history data: Butts, C.T., &
Pixley, J.E. (2004). A structural approach to the representation of life
history data. Journal of Mathematical Sociology, vol. 28, pp. 81-124. I think
the paper is available online at Carter Butts' site but I'm not so sure. Just
google it unless you have access to ScienceDirect where JMS is stored.

- Hello Rick,
I believe temporal changes can be represented
through colour in a network. Nodes coming into the network at different times
can have different colours. Similarly, links set up at different times can also
be colour coded. In a small network this would be possible to do by hand, but I
don't know (would like to know) if there is a program that can do this.
Intensity of linkage is generally represented by thick lines. Best Aparna

- Rick,
We have been building a tool that visualizes the
temporal evolution of social networks by creating interactive movies where
discrete states are animated using "inbetweening" of frames. See

Identifying linkages between mailing lists,
that may be of interest to mailing list members (21/09/04)

Hi list members
I have just been reading Chapter 1 of Ronald
Burt's Brokerage and Closure, and noted one phrase - "Instead of seeing people
as the source of information, clusters are the source and people are the ports
of access to the information that circulates around them"
This prompted me
to reflect on mailing lists as clusters and how they might be linked by
overlapping membership. And how members of a given list are unlikely to be
aware of all the links other members of that list have to other lists. Some of
which might be of interest to them.
Since I moderate three separate lists,
relating to my areas of work, I thought I would ask members of SocNet about any
known examples of research into overlapping mailing list membership. I am
especially interested in the survey methods used, whether by email or by
webpage based surveys, or both. But the actual results would also be of
interest as well.
regards from Rick |

Hi Rick,
A couple of years ago I've done a sort of a social
network analysis of a particular mailing list:
http://www.math.upatras.gr/~mboudour/articles/tgn.pdf
Although I haven't done anything else since then, I think I'm still interested
in the area and if you discover any new ideals, please let me know.
