Web wide crawl with initial seedlist and crawler configuration from March 2011. This uses the new HQ software for distributed crawling by Kenji Nagahashi. 
  
 What’s in the data set: 
  
  
  
 Crawl start date: 09 March, 2011 
  
 Crawl end date: 23 December, 2011 
  
 Number of captures: 2,713,676,341 
  
 Number of unique URLs: 2,273,840,159 
  
 Number of hosts: 29,032,069 
  
 The seed list for this crawl was a list of Alexa’s top 1 million web sites, retrieved close to the crawl start date. We used Heritrix (3.1.1-SNAPSHOT) crawler software and respected robots.txt directives. The scope of the crawl was not limited except for a few manually excluded sites. 
  
 However this was a somewhat experimental crawl for us, as we were using newly minted software to feed URLs to the crawlers, and we know there were some operational issues with it. For example, in many cases we may not have crawled all of the embedded and linked objects in a page since the URLs for these resources were added into queues that quickly grew bigger than the intended size of the crawl (and therefore we never got to them). We also included repeated crawls of some Argentinian government sites, so looking at results by country will be somewhat skewed. 
  
 We have made many changes to how we do these wide crawls since this particular example, but we wanted to make the data available “warts and all” for people to experiment with. We have also done some further analysis of the content. 
  
 If you would like access to this set of crawl data, please contact us at info at archive dot org and let us know who you are and what you’re hoping to do with it. We may not be able to say “yes” to all requests, since we’re just figuring out whether this is a good idea, but everyone will be considered. ||||| Lately, at Broadsheet, we've been writing a lot about the fashion industry , glossy women's magazines , plus-size models and Photoshop disasters . It's difficult to quantify the effects of Christian Louboutin's howling about Barbie dolls' cankles, on one hand, and Glamour's newfound (and likely temporary) commitment to showcasing models with a variety of body types on the other. But a new study hints at the impact such a weight-obsessed culture may be having on a particularly vulnerable demographic -- teenage girls. 
  
 At first glance, a paper published in the journal Pediatrics may seem to imply that young women are virtually unaffected by body image: As The Washington Post's The Checkup blog reports, researchers found "no association between high-school girls' body-mass index -- which indicates whether a body is under-, over- or of normal weight -- and their ever having had sex." But once the University of Pittsburgh team began to break down their results by high-school girls' race, perceived weight and a matrix of especially risky sexual behaviors, the findings became more complicated. 
  
 Overall, the study found that underweight girls, as well as those who were or believed they were overweight, were less likely to use condoms than their normal-weight counterparts. Of the many things this might suggest, what seems obvious to me is this group's lack of agency and self-worth. Girls may be seeing their (real or perceived) larger size as a flaw they must compensate for, and those with low self-esteem may already be starving themselves. (Personally, I'd be interested to see how much overlap there was between the group of girls who were actually underweight and the group that considered itself to be overweight.) 
  
 And the findings only get stickier when race enters the equation. Here's how The Checkup breaks them down: 
  
 Caucasian girls who thought they were underweight -- whether they actually were or not -- were more likely to have had sex and to have had four or more sexual partners than those who thought their weight was normal. Caucasian girls who were truly overweight were less likely to use condoms. 
  
 Underweight African-American girls were less likely to use condoms than those of normal weight, and overweight African-American girls were more likely to report four or more sexual partners. 
  
 Latina girls of all weights were more likely to engage in a wide variety of risky sexual behaviors, from lack of condom use and sex before age 13 to having more than four sexual partners during their teens and using alcohol. 
  
 These results are, of course, all over the map, and more research is likely necessary to determine why the racial differences are so pronounced. But a few common threads emerge: Girls who are or believe themselves to be over- or underweight seem most likely to be leading dangerous sex lives. And, for some reason, young Latinas are especially vulnerable, regardless of real or perceived weight. 
  
 So, now that we are beginning to understand how weight, race and body image can play into girls' early sexual experiences, what can we do to decrease their risk-taking behavior? For Dr. Aletha Akers, the lead author of the study and an assistant professor of gynecology and and reproductive sciences at Pitt, it comes down to better sex education. "This study will contribute to sexual health education prevention efforts, which can be tailored to address how cultural norms regarding body size may influence adolescent sexual decision making," she says, in a press release. "Knowing how a girl perceives her weight may be just as important as knowing her actual weight." More specifically, the study concludes "that girls at weight extremes and those from different racial backgrounds may have unique sexual health education and prevention needs." 
  
 I have no quibble with Akers' recommendations; in fact, I hope politicians and those who design sex ed curricula are listening to what she has to say. But I think it's also important to point out that not all sex education happens in school. If we want girls to feel good enough about themselves that they wait until they're ready, practice safe sex and avoid other risky behaviors, we're also going to have to help them interpret the messages they're getting from more informal sources -- from friends and siblings to magazine and TV. |||||

According to a new birth control PSA, the best reason to practice safe sex? “Guys are a@#$%^&.” Bloggers who saw the ad at this weekend’s third annual Sex:Tech conference? Not amused. The ad, which features stereotypical, caricatured guys drinking beer and talking about “titties” and threesomes, does “more than just offend anyone who is male or happens to respect or care for males." It "defeats the supposed purpose of the ad: sex education,” writes Tracy Clark-Flory on Salon. Clark-Flory quotes Shelby Knox, who writes on Tumblr that the ad flies in the face of that purpose: “getting young people to unlearn gender stereotypes around sex.” Stereotypes like the ones the ad parades around, like “men are pigs with raging hormones that can only process sex on a Neanderthal level.” A scan of the organization’s YouTube channel yielded quite a few more bizarre PSAs—watch them all in the gallery.
