## Social Networks for Charity

August 22, 2012## Math Soc Pre-ASA Conference, Thurs. Aug 16

August 14, 2012As was announced on the website last spring:

The fifth Joint Japan-North America Mathematical Sociology Conference will be held on Thursday, August 16, 2012 in the Colorado Convention Center, Denver, Colorado. The conference focuses on advancement of mathematical sociology worldwide and fosters friendship among those whose work is on mathematical sociology in all countries. Thus this is a wonderful opportunity to know cutting-edge topics in mathematical sociology and to meet people who share great enthusiasm for it.

To register, please download this form and follow the included instructions. If you have questions please e-mail Yoshimichi Sato.

Unfortunately I will miss most of it, but look forward to meeting people there towards the end of the day.

## The Formation of the Mathematical Sociology Secion, 1994-1996

July 22, 2012Young sociologists might assume that the section has been around a long time. I just came across this:

History of the Formation of the Section, 1994-6

by David Heise, Indiana University, Chair of the section 2003-4. This appeared in The Mathematical

Sociologist, Newsletter of the Mathematical Sociology Section of the American Sociological Association ,

Fall 2003

The first formal activity leading to the Mathematical Sociology Section occurred at a Professional

Workshop instigated and chaired by John Angle at the 1994 American Sociological Association annual

meeting in Los Angeles. After this workshop revealed genuine interest in creating a section, Eugene

Johnsen, with the assistance of a Steering Committee, produced a Mission Statement for a Mathematical

Sociology Section and, later, the By-Laws. The Steering Committee consisted of most of those involved in

the 1994 Workshop: John Angle, Stephen Berkowitz, Phillip Bonacich, Scott Feld, Sharlene Hesse-Biber,

James Hollander, Guillermina Jasso, Eugene Johnsen, Joel Levine, Timothy Liao, David McFarland, Alton

Okinaka, John Skvoretz, and Geoffrey Tootell.

A determined effort was made in the early years to bring the group’s interests to the attention of

sociologists in general and to display vital activities to the ASA. Eugene Johnsen organized and chaired a

Professional Workshop on “The Practice of Mathematical Sociology” at the 1995 ASA Meeting in

Washington D.C., with five invited speakers presenting papers. For the 1996 ASA Annual Meeting in New

York the section-in-formation proposed and received ASA approval for a Didactic Seminar by Stanley

Wasserman on social network analysis. At the 1997 ASA Meeting in Toronto, Phillip Bonacich presented

a Didactic Seminar, sponsored by the recently formed Mathematical Sociology Section

## Finding Data

July 16, 2012## ugh!!!

June 19, 2012It’s been a while, i know. So something dramatic must have happened. Multiple dramatic things have happened, but one in particular drove me to dust off my WP login. This article on obesity has been rapidly making the rounds (i’ve seen it linked no less than a dozen times since yesterday afternoon). It’s got lots of interesting information in it and easily quotable lines. But in virtually* every single *cite i’ve seen of it so far (on Facebook, news articles, etc.), the same finding has been quoted as the most striking punchline of the article, but has, in

*misrepresented what that finding actually is. The line from the article that matters is this (from the abstract):*

**every case**North America has 6% of the world population but 34% of biomass due to obesity.

The quotes of that finding i’ve seen thus far however have inevitably been framed as:

North America has 6% of the world population but 34% of biomass.

A seemingly innocuous edit, but resulting in a complete misrepresentation of what the study actually found. What the analysis shows is that if you limit the analysis only to account for the obesity in the world (i.e., we look *only* at the “excess” weight) on the planet, N. America accounts for 34% of that amount. Not 34% of all biomass. In order for the citation as it’s making the rounds to be true, the average N. American would have to weigh 371 kg (or roughly 818 pounds; calculations stem from Table 3 in the paper). Now part of the problem is the way things are written as most people aren’t used to having to do a little simple math to digest their research blurbs, but sometimes it’s completely necessary to be sure you aren’t completely lead astray.

Now, i’m not trying to diminish the findings in the article, as i think they have done a good job of demonstrating how weight is unevenly distributed across the globe. Just not in the way people are saying they’ve said it is.

## Neal Caren on citation patterns in sociology

June 2, 2012What articles and books have sociologists been citing a lot recently? See the list compiled by Neal Caren. He also made a cool network diagram showing which articles are cited together.
