Isolated social networkers

Thursday, May 19th, 2005

[This on CT. Worth checking out for comments.]

Some physicists have come out with a paper on the Eurovision song contest. Of course, we at CT like to be ahead of the curve and thanks to Kieran’s ingenuity reported similar findings over a year ago. So much for this being “new research”.

There has been much excitement about and focus on social networks in the past few years ranging from social networking sites to several high-profile books on the topic.

Interestingly, much of the buzz about recent work covers research by physicists. It’s curious how physicists have expanded their research agenda to cover social phenomena. I thought their realm was the physical world. Of course, since social phenomena are extremely complex to study, as a social scientist, I certainly welcome the extra efforts put into this field of inquiry.

What is less welcomed is watching people reinvent the wheel. Sure, partly it’s an ego thing. But more importantly, it’s unfortunate if the overall goal is scientific progress. Much of the recent work in this area by physicists has completely ignored decades worth of work by social scientists. If we really do live in such a networked world where information is so easy to access, how have these researchers managed to miss all the existing relevant scholarship? Recently Kieran pointed me to an informative graph published by Lin Freeman in his recent book on The Development of Social Network Analysis:


People whose overall work focuses on social networks are represented by white dots, physicists by black ones, others by grey circles. (Click for a larger version of the image.) As is clear on the image, the worlds exist in isolation from each other. It would be interesting to see year-of-publication attached to the nodes to see the progression of work.

I have been meaning to write about all of this for a while, but John Scott from the Univ. Essex addressed these issues quite well in some notes he sent to INSNA‘s SOCNET mailing list a few months ago so I will just reproduce those here. (I do so with permission.)

Research blog

Tuesday, May 17th, 2005

I have started a new blog.. haha, because I don’t have enough online endeavors already.:-) It is for my research group. In addition to covering research updates, we will also post general IT-related news items. That’s the plan for now. It’s called the Web Use Project Blog. We cover more than “Web use” in a strict sense, but that name still works for much of my work and for lack of a better name I will continue to use it for now.

JCMC special issue on search engines

Purchasing power through the years

Thursday, November 11th, 2004

Here’s a nice little online tool to help figure out how much $X from a given year would be worth today in terms of its purchasing power. [Hat tip: NeatNew]

Visiting ILA

Wednesday, September 29th, 2004

I gave a lunchtime talk at the annual meetings of the Illinois Library Association today. It was more of a skit than a talk, actually. Ed Valauskas – known in IT-research circles mostly for editing First Monday – and I were invited to participate on a session with the following title: If Google is God Who are Reference Librarians? (not our title, theirs). Given that we were lunchtime speakers, we decided to take a lighter-than-usual approach and we prepared a skit for the occasion. I was the venture capitalist approaching Reference Librarians, Inc. for a potentially lucrative arrangement about tweaking their referral services. Then I played a first-year college student asking all sorts of questions from Ed, the reference librarian, about obtaining information regarding various issues that come up in the life of a student newly arrived on campus. In response to my questions, he just “happened to” recommend the various products suggested by the venture capitalist. In the end Reference Librarians, Inc. decided to return some of the funds to the funders, because the goup’s members felt that they were not ready to compromise their service in that way.

After the skit, we spent a few minutes discussing the ways in which reference librarians do offer added value when compared to search engines. We wrapped up on the point that one of the biggest challenges reference librarians seem to face is more a question of PR. They need to help people understand that they do offer much more than running simple queries on a search engine may yield, especially for the average user.

Nice results

Thursday, September 23rd, 2004

I have not been blogging much (I don’t just mean writing, I also mean reading), because I am really close to sending off an article for review. Any moment I have at my machine that is not taken up by immediate email correspondance, I want to spend on my paper. But I know that some people stop by the blog regularly and I don’t want to disappoint by not having anything new here for days on end when they visit. There all sorts of things on my mind for blogging, but I just don’t want to take the time from my piece now.

I’ve figured out a middle ground: I’ll briefly blog about the paper I am writing. 🙂 This may get a bit technical, but fellow geeks who stop by here may appreciate it.

One of the goals of my dissertation project was to figure out survey measures of people’s actual online skills. In most of the existing literature, when people include measures of computer skills (the existing lit is mostly about computer-use skill not online skills), they rely on people’s self-perceived abilities. That is, researchers simply ask users to rate their skill. As you can imagine, this measure may not be very good. However, collecting data on actual skill is quite time-consuming, labor intensive and expensive, so we often don’t have a choice but to rely on survey measures. The question then is whether we could come up with better survey measures.

In my project, I measured people’s (one hundred randomly selected adult Internet users’) ability to find various types of information online and their efficiency (speed) in doing so. I also asked participants to rank their skills (as per the traditional skill measures) and to rate their understanding of a few dozen computer and Internet-related items. (There’s more on what I did to see whether perceived understanding is a good proxy for actual knowledge, but for that you’ll have to read the paper.;-)

I then checked the correlation of the various survey measures with actual skill. I constructed an index measure of skill based on the most highly correlated survey questions. I then looked to see to what extent the self-perceived skill measure explains the variance in actual skill versus the extent to which my index measure based on knowledge items explains the variance in actual skill. I am happy to report that my index measure is a better predictor of skill than people’s self-perceived abilities.

An additional exciting bonus is that some of my survey measures were replicated on a national data set (the General Social Survey 2000 & 2002 Internet modules) so others can use these better measures as well.

I’m excited. The study I did was pretty risky in some ways. There was no guarantee that I would even find any variance on the most crucial variables (such as skill). But I did. And now these findings with the new versus traditional survey measures of skill suggest that there is something generalizable there, which is exciting.

Yes, I’m a data geek.

TSB Speaker Series

We have finalized our Technology and Social Behavior Speaker Series for the 2004-2005 academic year. We have quite an exciting line-up, it’s fun to be in such an interdisciplinary group.

Memories of my dissertation

Saturday, September 11th, 2004

In the Fall of 2001 as I was coding and analyzing data for my dissertation on how people find content online, I realized that some Web sites had changed a few design elements after the events of 9/11. I put up a little Web page documenting some of these changes because I thought they were interesting and worth archiving. I wish I would have had time to find more.

There were some more direct links between 9/11 and my dissertation. One was logistical while the other brought it all up close and personal. I think about these issues sometimes, especially the latter, and thought today would be an appropriate day to share them.

I did the recruitment of participants for my project by sending letters and brochures to randomly selected residential addresses in Mercer County, New Jersey. It turned out that this was precisely the area where post offices were shut down due to anthrax concerns so letters that I thought had been sent out to residents were not leaving the post office and letters that may have gone out before the sending office closed down were not arriving at the other end. This led me to delay the study even further – having put it on hold right after 9/11 – in order to be able to pursue the original course of recruitment. I think a mention of anthrax thus made it into my dissertation in a footnote.

The other link is more interesting and touching. Respondents came to my university’s campus to participate in the study. First, I sat with them and orally administered a questionnaire about their general Web use patterns and some additional questions. One issue of particular interest to me is the role of social support networks in people’s Internet use. I had a question on the survey that asked about whether there were people the respondent knew to whom to turn with questions about Web use. One day a participant gave a curious response to this question: he said that there used to be someone. Since you know the context of my blog post, you may see where this is headed. But in the context of the interview this was a curious response and so I asked again to confirm that I had heard the response correctly. I looked up from the questionnaire and asked: “You used to have someone you could ask but that is no longer the case?” He looked at me and said: “It was my son. He used to work in the Twin Towers.”

Digital divide symposium

Sunday, August 29th, 2004

I spent the last few days in Minneapolis at the Carlson School of Managements of the Univ. Minnesota participating in a great digital divide symposium. Although I have been doing research on this topic for years, I got to meet several people new to me who are working on interesting and important projects in this area. Many of them were from management and information systems/science programs, a field whose interest in the digital divide may not be obvious to some. One interesting question that came up more in the proposal to the meeting than the actual workshop was whether the existence of a digital divide is bad or, in fact, possibly good for business. This was a whole new angle on the topic, and although many would likely claim that this is not the right approach to take to the question, it is certainly an interesting one.

Extending Internet access to low-income communities

Friday, August 13th, 2004

I was quoted in a Washington Post article on Monday. The piece discusses a fascinating project by the One Economy Corporation that has managed to get people in low-income communities connected to the Internet. [Reading the article requires a login. You can get one at BugMeNot.] I comment on the importance of skill beyond achieving access. The One Economy Corporation certainly does more than “just” providing access. For example, they have developed a helpful portal for their users with information about jobs, government services and lots of other material that is likely of interest to users.
