Network Data Collections

Thanks to a stocnet user, this list of useful network data repositories came along.

I added them to my Diigo list of sna and data.

Mapping Projects, poeple, and orgs: Software to map square and bimodal networks

Sent to Socnet.

Hi,
I sketched on a napkin the other day a “map” of social innovaiton at my campus.
On it I had as “nodes”
  • – Projects
  • – Actors (like students, faculty, centers)
  • – Amorphous constituencies like “faculty” from which actors could come, or whcih projects could serve or interest.
I drew some ties for relations like
  • – created
  • – fund
  • – are interested in
I was thinking, I could make a “figure” of this, but any new data would involve manual additions.
Is there a software tool anyone recommends?
In mu ind, it is like a hybrid of a square matrix, like all the actors to the actors, and a bimodal network, actors or constituencies to projects.
Plus, I was thinking of differing relations which could be visualized.  So, maybe behind the visualization are different matrices that can be added or removed from the visualization.
Finally, I was thinking of this evolving over time.
I realize some of this relationships may not theoretically make sense with some kinds of lay out algorithims.  For example, I am not sure what it would mean to try to find the most central node when there are both actor-actor and actor-object (bimodal) relations, but at the moment, I was more looking for a tool to visualize these relations and dynamically update data to create newer visualizations.
I added a picture if that helps…

Graph your Facebook friends

Bernie Hogan is my new hero.  He has written  a lovely little app that allows you to extract your Facebook network in a format that you can use in GUESS or UCINET.

Network Liabilities- Citigroup Pays for a Rush to Risk

The Reckoning – Citigroup Pays for a Rush to Risk – Series – NYTimes.com
But many Citigroup insiders say the bank’s risk managers never investigated deeply enough. Because of longstanding ties that clouded their judgment, the very people charged with overseeing deal makers eager to increase short-term earnings — and executives’ multimillion-dollar bonuses — failed to rein them in, these insiders say. [my emphasis]

This NY Times article points out that the normal risk management controls at Citigroup that should have reined in exposure to CDOs [collateralized debt…] were thrwarted.

By?

“ties that clouded judgment.”

I suppose that is a network liability.  Every organization is cris-crossed  with network ties.  The question is why these had such an impact.  Org Culture?  Greed?  Something structural in the network?  The technology of communication?

PhD in Social Network Analysis

Maybe there are former students out there who check up on me…

Anyway, here is the skinny on a PhD program staffed with some pretty big names (and nice people to boot!).

LINKS, the International Center for Research on Social Networks in Business at the University of Kentucky, has openings for students in our Ph.D. program in business administration, with an emphasis on organizational research from a social network perspective. The openings are for Fall 2009.

Our research emphasizes examining organizational behavior and strategy from a network perspective, and our faculty and students publish extensively in the major management journals. Students are trained to become faculty at research-intensive business schools worldwide. Network-oriented faculty include Steve Borgatti (theory & methodology; knowledge management); Daniel J. Brass (power, ethics, innovation, technology), Giuseppe “Joe” Labianca (conflict, group social capital), Ajay Mehra ( individual differences; performance), Ikenna Uzuegbunam (strategy and innovation management; entrepreneurship), and Leslie Vincent (marketing and innovation),

The application deadline is February 1, 2008, but early applications are encouraged for full consideration. Please visit http://gatton.uky.edu/Programs/PhDBA/ManagementArea.html and contact Ajay Mehra (ajaymehra1@gmail.com<mailto:ajaymehra1@gmail.com>) to learn more about our Ph.D. program.

Soc Net Books to Explore

Charles Kadushin sent out an email awhile ago asking for reviewers for Social Networks.  i would love to see the network folks sink their teeth into the explosion of general audience/practitioner books out there.

he listed the following at the time as possibilities:

Social Networks and Marketing, by Christophe Van den Bulte and Stefan Wuyts, Marketing Science Institute, 2007.

Andy Sernovitz and Guy Kawasaki, Word of Mouth Marketing: How smart companies get people talking. Kaplan Publishing, 2006 Mark Hughes, Buzz Marketing, Penguin 2006 Dave Balter and John Butman, Grapevine: the new art of word-of-mouth marketing. Penguin 2005.

Add Seth Godin’s Tribes: We need you to Lead us (2008) to the list.

WOW and SNA

Stumbled into a paper of networks of players, guilds in World of WarCraft [WOW].  Visual complexity had the image.

U Mich researchers map PVE interactions.

U Mich researchers map PVE interactions.

This led to a paper that is worth looking at to see how they extracted the data for the network analysis.

Indirect Social Influence

SOCIOLOGY: Indirect Social Influence — Denrell 321 (5885): 47 — Science
To learn more about these mechanisms, we need to broaden studies of social influence and belief formation to include the phases of learning and information collection that precede decision-making and judgment.

The above quotation from Science summarizes a brief yet interesting overview of how indirect influence matters.  The gist is that the exposure I have to infomration, as a result of my network connections or position, can bias my “rational” decision-making.  Its not that we are all weak-willed lemmings who do what the joneses do, it s that in the face of difficult to find information, we may rely on information gathered through netwokr ties to make decisions.  And by separating network effects into direct influence on disposition and indirect influence though information gathering, we can better analyze influence.

Fine.  Seems a bit of a round-about way to get there, but I suspect it makes network effects more palatable to economists or game-theory types.

Social Networks gains another level of salience

While over at socnet, there is a discussion of how “social networks” has become totally co-opted and stolen by the rise of the social networking sites/services (MySpace, Facebook, Okrut, LinkedIn, etc), i stumbled on to the new HP TouchSmart computer marketing campaign.  By the way, the author of the post above, Guy Hagen, is totally correct that social networks are as old as the species while SNS are, well, younger.

(I wonder what is the first SNS?  Orkut?  Tribe.net? It would be nice to have a brief history of SNS.  What would minimal definition be?  Profiles+relationship building+messaging system… Is that enough?)

The HP touchSmart, which looks pretty cool, bills itself as the one machine that will enable you to manage your digital life.  “It puts your digital life at your fingertips giving you instant access to info, entertainment, and social networks.”  So, not only has social networks as a term become a whole genre of applications, but even a class of functions like photography, word processing, or data management.

Applied SNA-ASNA 2007 // Call for Papers

ASNA 2007 // Call for Papers
ASNA 2008 will primarily provide an interdisciplinary venue with focus on applications of social network analysis; however, submissions on theoretical and methodological issues regarding SNA are also welcome.

I don’t know how many times I can bounce over to the EU in the Fall, but this looked interesting.  I have been itching for awhile to get a better handle on applied SNA.   Outside of Valdis Kreb’s InFlow and Rob Cross’ Network Roundtable (and The company Visible Path), I don’t know much about applied SNA over here.

I should find out what kinds of meetings are over here of this nature.
