US 1549 and UA 232

Yesterday’s images of passengers standing on the wing of a submerged Airbus in the Hudson River were both terrifying and phenomenal. That all 155 souls on board US (AWE) 1549 survived is a testament to the skill of the crew and first responders (and those great ferry operators).

A number of news sources have run profiles of the Captain, C.B. “Sullly” Sullenberger, describing his training and heroism. While his heroism is unquestionable, I found that I was more interested in his training – which includes an B.S. and M.S. in Psychology, and an M.P.A. Furthermore, Sully is an expert in Crew Resource Management (CRM), and he holds a highly prestigious role of a Check Airman at U.S. Airways.

Unit Structures readers may have a passing familiarity with CRM, as it is the subject of Ch. 7 of Malcolm Gladwell’s most recent book, Outliers. CRM is a management system that emphasizes communication, awareness and decision making by an airplane’s crew. As Gladwell points out, most modern air accidents are not due to mechanical failure, but rather human error (and largely communication errors).

Many of the profiles of Sullenberger have emphasized his history flying fighter jets as a factor in this successful “ditch.” As I watched video of the flight path, it became clear that this was not just a “skill” landing, but also one that drew on exceptional resource management. As Sullenberger takes off from LGA and experiences catastrophic engine failure, he faces multiple problems. He is in a very dangerous limbo (between LaGuardia Tower and New York Center ATC), flying in the heavily congested New York airspace. He is heading north and overland, eliminating his ditching options. Finally, he is above one of the most densely populated areas in the world, and falling fast. Rather than flying further inland, Sullenberger pivots the plane over New York City, avoiding other air traffic and getting over the river quickly. The touchdown was most certainly skill, but the decisions Sullenberger makes in the seconds leading up to it show evidence of clear thinking, good decision making, and tremendous awareness of situational factors. This is CRM executed at its finest.

CRM has played a role in mitigating other accidents and near-misses.  Perhaps most famous is the crash of United Airlines Flight 232, which crashed while attempting an emergency landing at Sioux Gateway Airport (Sioux City, IA).  UA 232 has completely lost its hydraulic systems, a fully catastrophic failure.  Dennis Fitch, a UA Check Airman (with expertise on that particular airframe) deadheading on the flight, offered his assistance to the crew.  Utilizing CRM, the crew worked together and managed to survive a nonsurvivable situation (185 of the 285 on board survived the crash).

What strikes me about yesterday’s accident and UA 232 is the similarities between Denny Fitch and Sully Sullenberger.  Both are check airmen.  Both are experts in CRM.  Both have extensively studied Human Factors.  Both are highly regarded, prestigious pilots within their organizations.  And both happen to be exactly the pilot you want on board a stricken aircraft, because they have both the skill and training to handle the situation.  With all of the cutbacks and setbacks in the airline industry, it is heartwarming to know that corporate still values expertise in cockpit.

If you’ve made it this far you’re probably wondering about this little topical departure.  While I do admit to being interested in flying (you do it enough, you start to wonder about what goes on behind the scenes), it is pure coincidence I know anything about these topics.  First and foremost, CRM and incident communications comes up all the time in management and org theory lit that I use in my work (my favorite article on the matter being Weick’s ASQ Mann Gulch paper).  Gladwell’s recent treatment also provided context.  But the real reason is that a few weeks ago I watched Errol Morris’ interview with Denny Fitch, which is riveting and spectacular.  You can find it on YouTube (Part 1, Part 2, Part 3, Part 4, Part 5, Part 6).

Scott Golder on Peter Kollock

Scott Golder, formerly of HP Labs and now Cornell Sociology, is blogging.  One of his first posts is about the untimely passing of Peter Kollock:

I never got to meet Peter Kollock in person, but my decision to pursue sociology was influenced by his sharp work on social dilemmas and virtual communities, the latter being something few sociologists were thinking of at the time.  He was a role model for me in the Mertonian sense; I’m just at the beginning stages of a sociology career, and Peter has been an example of what to aspire to.

In particular, his 1998 Annual Review of Sociology paper on social dilemmas was huge for me. It’s a clear discussion of many kinds of collective action problems, and demonstrated an approach to the study of cooperation and competition that I preferred immensely to the more formal and abstract treatments I’d read by economists. I still go back to this paper all the time.

Often with his former student Marc Smith, Kollock showed why virtual communities are amenable to sociological study (Marc posted a touching memorial on his blog, connectedaction).  Kollock and Smith’s 1996 chapter [1] on Usenet presciently tackled bandwidth as a common good, as well as socialization, monitoring and sanctioning in virtual groups.  Kollock also did some of the earliest work on eBay; [2], looking at how reputation works in a world with near-infinite exchange partners and few channels for sharing social information.

Like Scott, I never met Peter (I don’t think I’ve ever even been in the same room as him), but his work was tremendously influential (a sentiment echoed by everyone doing net research).  The Smith and Kollock Communities in Cyberspace book was one of my earliest acquisitions in my research and has always stayed within a few feet of my desk.  This is a tremendous loss.

New Report from Pew: Adults and SNS

A new report from the Pew Internet and American Life Project shines light on social network use by adults:

The share of adult internet users who have a profile on an online social network site has more than quadrupled in the past four years — from 8% in 2005 to 35% now, according to the Pew Internet and American Life Project’s December 2008 tracking survey.

While media coverage and policy attention focus heavily on how children and young adults use social network sites, adults still make up the bulk of the users of these websites. Adults make up a larger portion of the US population than teens, which is why the 35% number represents a larger number of users than the 65% of online teens who also use online social networks.

Online Social Networks, Spring 2009

As of this morning, UNC is back in session for the spring term – how the winter break flies!  This semester I’ll be teaching my Online Social Networks course.  This is the third time I’ve taught this particular course, and it is a lot of fun.  I’m in the midst of updating the syllabus, which I’ll post to the blog when I finish.

Of potential interest to my readers is an article I discovered in the most recent issue of Portal.

Academic Libraries, Facebook and MySpace, and Student Outreach: A Survey of Student Opinion.
This study surveyed 366 Valparaiso University freshmen to discover their feelings about librarians using Facebook and MySpace as outreach tools. The vast majority of respondents had online social network profiles. Most indicated that they would be accepting of library contact through those Web sites, but a sizable minority reacted negatively to the concept. Because of the potential to infringe on students’ sense of personal privacy, it is recommended that librarians proceed with caution when implementing online social network profiles.

I’ve only skimmed this article, but I am collecting resources on social networks and libraries for one of our classes this semester. There is a growing body of literature on libraries and social networks – if you know something noteworthy feel free to leave a comment.

I would be remiss without congratulating Lori Eakin and Jeff Pomerantz, colleagues at SILS, for their study Virtual Reference, Real Money: Modeling Costs in Virtual Reference Services which appears in the same edition of Portal.
