“Human Trails In Cyberspace

Social scientists create maps of online interactions

Blogs

Multimedia: Maps and audio charting human interactions in cyberspace

If the Internet is a new kind of social space, what does it look like?

That's a question of particular interest to social scientists eager
to see what cyberspace might reveal about the nature of human behavior.

Researchers, after all, have long sought to map social groupings and
interactions in the physical world. Now, with so much activity on
computer networks, scientists can collect vast amounts of hard data on
human behavior. Each blog points to other blogs in ways that reveal
patterns of influence. Online chats can be tallied and parsed. Even the
act of clicking on links can leave trails of activity like footprints
in the sand….




A MUST read: The (Ongoing) Vitality of Mythical Numbers

“The (Ongoing) Vitality of Mythical Numbers
<http://www.slate.com/id/2144508/

This article serves as a valuable reminder that we should view
all statistics, no matter how frequently they are used in
public arguments, with skepticism until we know who produced
them and how they were derived.”

Sometimes what is NOT there is more important
Jun 27th, 2006 by JTJ

Steve Bass, a PC World columnist, had an item this week that reminds us that a good analytic journalist is always thinking about what is NOT in the data.  He writes:


Risky Business: Stealth Surfing at Work


Not long after I told my buddy about Anonymizer, I heard from another friend, an IT director for a fairly large company. It may
not be such a good idea to surf anonymously at the office:


“I recently had an employee, an MIS employee at that, fired. He was using Anonymizer at work. We have a tracking system (Web
Inspector) and I kept noticing that he was leaving no tracks.


“I consulted with my supervisor and he decided that I should analyze the employee's system. I found footprints, hacking, and a
batch file he used to delete all Internet traces. So I sent the system off to forensics and they found all the bits, each and
every one. We're now in legal limbo. The employee is being fired, not for the hacking or the batch file, but for using the
Anonymizer.


“Thought maybe you'd be interested in hearing about the dangers of using the Anonymizer in the workplace. They claim the
Anonymizer hides your tracks at work–but I guess not all of them.”


–Name Withheld, Network and Computer Systems Administrator


I asked George Siegel, my network guru, what he thought. Here's what he said: “It's interesting to note how the user was
initially discovered — by the absence of anything incriminating. Network professionals have logs showing just about everything
that goes on and they look for any deviation from the norm. I can always tell who is up to no good… their computers are
scrupulously clean.





A most-helpful statistics site
Jun 25th, 2006 by JTJ

From the good folks at Internet Scout:

HyperStat Online [Last reviewed December 19, 1997]
http://davidmlane.com/hyperstat/

Does the mere mention of the phrase “sampling distributions” bring a tingle
to your spine? Visitors to this site will fear this basic concept of
statistics (along with many others) no longer, as it does a fine job of
explaining them in a fashion that is both lucid and jargon-free. Created and
maintained by Professor David M. Lane of Rice University, the HyperStat
Online site contains an online introductory statistics textbook, complete
with sections on normal distributions, confidence intervals, prediction, and
the logic of hypothesis testing. Each section contains a number of discrete
subsections, and users can feel free to browse around at their leisure.
Professor Lane has also included a number of external links to related
resources, including a visual statistics site by David Krus of Arizona State
University and a “Stat Primer”, authored by Bud Gerstman of San Jose State
University. Overall, this site is tremendously helpful, and will be of great
assistance to those entering the world of statistics for the first time.

Challenging the DATA of conventional wisdom
Jun 12th, 2006 by JTJ

Kudos this morning to National Public Radio's reporting on a Duke professor who thought the numbers on Chinese engineering grads seemed a little off kilter.

Figures on Chinese Engineers Fail to Add Up

Listen to this story... by  


Morning Edition, June 12, 2006 · A report cited in The New York Times
and quoted on the House floor claimed China graduates nine times as
many engineers as the U.S. Skeptical, a Duke professor had students
check the numbers.
