The Science of Sexism: Primate Behavior and the Culture of Sexual Coercion

by Eric Michael Johnson in The Primate Diaries in Exile

The latest stop in the #PDEx tour is being hosted by The Intersection at Discover magazine.Despite the advances our society has made for women’s rights and sexual equality during the last century this example is just one more sign of how far we still have to go. It’s not an isolated incident. According to statistics compiled by the US Equal Employment Opportunity Commission there were 12,696 workplace sexual harassment cases filed in 2009 (which would be a fraction of the number that actually occurred) and 84% of these cases were brought by women. Businesses have gotten increasingly serious about cracking down on such abuses but last year they were still held liable to the tune of $51.5 million, the largest figure since 2001. What is going on here? Could this kind of gender inequality be an intrinsic feature of human nature that we’re stuck with or is it simply a failure to create an environment that prevents such behaviors from reoccurring?Primatologists and evolutionary biologists have taken this question seriously and have developed some surprising conclusions that could inform our approach to this issue. Unlike Randy Thornhill and Craig Palmer’s book A Natural History of Rape, a thesis that was criticized by scholars both in biology and gender studies, other evolutionary researchers have developed a much more balanced analysis. One example is from the recent edited volume Sexual Coercion in Primates and Humans by Martin Muller and Richard Wrangham. As they wrote in their introduction:[M]ales in a number of primate species appear to use force, or the threat of force, to coerce unwilling females to mate with them. . . Although the utility of this distinction has been disputed, there is no doubt that sexual coercion is a potentially important mechanism of mating bias within the broad framework of sexual conflict theory.Read the rest of the post here and stay tuned for next week's post hosted by Sex at Dawn at Psychology Today magazine.Reference:Martin N.

How To Fight Loneliness

by Rob Mitchum in ScienceLife

Loneliness is bad for your health. The work of John Cacioppo and others has proven this connection repeatedly over the last decade, finding links between loneliness and blood pressure, sleep quality, dementia, gene expression, and many other medical measures. The evidence has built to the point that loneliness could be considered a serious risk factor [...]... Read more »

War & Fish

by Journal Watch Online in Journal Watch Online

War isn’t the answer — but it wasn’t so bad if you were a Scottish haddock. A 6-year pause in commercial fishing caused by World War II helped cod, haddock and whiting populations in Europe’s North Sea recover from years of pre-war exploitation, according to a new analysis. The “accidental” reserve suggests that cold-water fish […] Read More »... Read more »

Briefings in Bioinformatics – our education paper is available now

by Jennifer in OpenHelix

Back in April I happened to mention that we (OpenHelix) were writing a paper on informal sources of bioinformatics education (in a Friday SNPets item) and we were asked to announce when the paper came out. Well, we got word late last week that the article has been published. The article appears in a special issue of Briefings in Bioinformatics that is devoted to bioinformatics education. I’m not sure if all the articles in the issue are available yet, but it looks like several are in the journal’s Advanced Access area. Bioinformatics education is an area (obviously) that OpenHelix cares deeply about & we are anxiously awaiting our copies of the full issue so we can read all the articles, but I digress…
The title “OpenHelix: bioinformatics education outside of a different box” was a cool suggestion from one of the article’s reviewers – my original title was much tamer (ok, more boring). Regardless of the final title, what we wanted to do in the article is to discuss informal sources of bioinformatics education. By education we do mean acquiring applicable information that allows a researcher to operate within the field of bioinformatics. By informal we mean outside of traditional, credit based classes and degrees. Essentially we provide a bit of the knowledge and know-how that we’ve gathered over years of working with hundreds of resources, thousands of workshop attendees, and countless online contacts about where a researcher, or librarian, or whoever can turn for various informational needs in the field of bioinformatics.
Our contention is that not everyone needs to program in order to manage and manipulate their biological data these days. There are SO many fine publicly available databases, algorithms, tools and more, it is just a matter of awareness and training for anyone to be able to reformat and analyze their personal data sets. We maintain that :
…bioinformatics education needs to do a minimum of four things:
1. raise awareness of the available resources
2. enable researchers to find and evaluate resource functionality
3. lower the barrier between awareness and use of a resource
4. support the continuing educational needs of regular resource users
In the paper we walk through each of these – we first describe example needs associated with the point, and then cover possible informal resources that meet the needs. The article includes tables of resources and links to them and many many references. We really hope that is a very useful resource in the field of bioinformatics education.  I am already looking forward to contributing to the next special education issue, both to hone my writing skills and to extend the information we can provide readers. Please do comment, email, whatever and let us know about the resources that you use, what you learned from the article, etc. Oh, here’s the citation info:

The woman whose new memories are erased each night

by Christian Jarrett in BPS Research Digest

Psychologists have documented what they believe to be a clinical first - the case of an amnesic woman whose memory for new material is erased each night that she goes to sleep (movie fans will recognise this as a plot device in the 2004 film 50 First Dates). Referred to as case FL, the woman developed these symptoms after she hit her head in a car accident in 2005, aged 48. Brain scans and neurological exams revealed no signs of brain damage, thus suggesting the woman is exhibiting what's known as psychogenic or functional amnesia - that is, symptoms in the absence of any detectable organic cause.

FL claims that on any given day her memory for newly acquired material is fine until she has a night's sleep, during which the new memories are erased (unlike standard cases of psychogenic amnesia, she says her memories from before her accident are preserved). FL's performance on lab-based memory tests was largely in keeping with her claims, with one key exception. Christine Smith and her team deployed some trickery, intermingling test items (scenes) from earlier in the day with items from previous days. FL's memory for items that she thought were from earlier in the day, but were actually seen on earlier days, was intact and comparable to the memory performance of healthy controls.

So was FL faking it, perhaps in pursuit of a compensation claim? Smith's team don't think so. Although healthy controls who were asked to fake FL's symptoms performed similarly on the memory tests, there were also differences. For example, unlike the healthy fakers, FL showed deficits in motor learning, and her confidence for test items dropped with repeated testing whereas theirs increased.

The researchers' theory is that FL truly believes she has the memory deficit that she describes and that unconscious processes may be involved in its manifestation. FL denied having seen the film 50 First Dates, which was released a year before her accident. However, she admitted that the film's female lead, Drew Barrymore, was her favourite actress, so she may have been aware of its plot. The film 'may have influenced FL's concept of how memory could fail after a car accident', the researchers said. 'The brain uses preexisting concepts of memory and through altered brain function creates a particular constellation of symptoms.'

What about treatment? Reassuring FL that evidence had been found for the intact functioning of her overnight memory proved unsuccessful. What did work was testing the limits of FL's memory-washing system. Thirty-six hours without sleep and her memories were okay. An hour's nap during the day and they were okay. In the end, it was established that FL can sleep at night for up to four to six hours at a time without experiencing the sense that she's lost the day's memories. By setting an alarm each night to wake her after bouts of three and a half hours sleep, FL has managed to overcome her strange condition. 'At our most recent contact (March 2010), she and her husband reported that she continues to use this regimen successfully,' the researchers said.

New land for agriculture coming mainly at the expense of tropical ecosystems

by Phil Camill in Global Change: Intersection of Nature and Culture


There have traditionally been two ways to produce more food for an increasing population:  Convert native ecosystems like forests and grasslands into agricultural fields (what we call “extensification”) or make the yields on existing croplands go up, through the use of things like machinery, fertilizers, irrigation, pesticides, and GMOs (what we call “intensification”).
Historically, these processes [...]... Read more »

Across the ~3 billion or so base pairs in the human genome there’s a fair amount of variation. That variation can be partitioned into different classes, somewhat artificial constructions of human categorization systems, but nevertheless mapping on to real demographic or life history events of particular importance. Some of the variation is specific to populations, [...]... Read more »

Self-Righteousness and Kink: Perfect Together?

by David Berreby in Mind Matters


Props to my colleague Lindsay Beyerstein for this great catch yesterday: Tea Party favorite Sharron Angle's campaign received a donation from someone who listed her employer as "husband" and her occupation as "slave." Maybe it's just a joke (boring). Or maybe this couple is in one of those Christian "submitted wife" relationships (unlikely, given that "slave" isn't the sort of rhetoric that culture promotes). But maybe this is an "out" dominant/submissive couple. That shouldn't be a surprise, if so. Contrary to stereotypes, there's good evidence that conservatives worldwide are more likely than liberals to have non-vanilla sex lives.
Obviously I'm not talking about high-profile Republican kink, like the $2000 the party spent at a bondage-themed strip club or the curious habits of some of its senators. We're looking at the rank and file. In this online survey, for instance, 81 percent of Republican respondents reported that they'd used blindfolds, handcuffs or other restraints during sex. Democrats came in at 77 percent on that one. Almost half the Republicans said they had filmed themselves during sex, compared to 38 percent of the Democrats.
Of course, the sample here was biased (it consisted of visitors to the website of Good Vibrations, the sex-toy store). A statistically sounder indicator is Benjamin Edelman's finding that in the United States, "red" states have the highest rates of subscription to online porn. You can read the paper, "Red Light States," in pdf form, here. Similarly, as P.Z. Myers showed last month, for Google searches of kinky pornographic terms ("horse sex," "rape video" and the like), the leading nations are officially cultural conservatives: Pakistan, India, Saudi Arabia and the United Arab Emirates.
Are these data signs of the allure of the forbidden? Maybe. Perhaps, though, they reflect what Chen-Bo Zhong and Katie Liljenquist call the "Macbeth effect," after Lady Macbeth's attempt to wash away her sins by scrubbing her hands. Some years ago, Zhong and Liljenquist found that people who'd been prompted to think about a past ethical lapse were more eager to wash their hands then were people who had been reminded of some virtuous act they'd done. The washing ritual had an effect on their behavior: Asked to give time for no pay to a desperate grad student's project, three-quarters of those who had not washed did volunteer. Of those who did wash, only 41 percent stepped forward to help.
Similarly, Simone Schnall and her colleagues have found that letting people wash has an effect on how they feel about using a kitten to get off sexually, taking money from a lost wallet, or other ethically dubious acts. Cleaning up, which makes people feel purer physically as well as morally, left them more accepting of the kitten-sex idea than were people who, not having washed, felt themselves to be a little dirtier.
We tend to think that a self-righteous sense of your own virtue makes you less accepting of "sin," however it's defined by your community. (Important caveat there: I'm not passing judgment on dom/sub couples or Pakistani "donkey sex" searches; rather, I'm focussing on the gap between ideology in the public square and whatever is whimpering, meowing or purring contentedly in one's private life). But maybe our expectations get it exactly backwards. Perhaps believing yourself to be the holiest, purest, most righteous and civic-minded paragon in the neighborhood is just the sort of mindset that makes a search for "camel sex," or "sub lifestyle," feel like no big deal.
