It’s a long story… (from the Archives of Sexual Behavior)

Sunday, August 24th, 2014

Behold the start (or perhaps the middle) of a twisted tale:

Be Careful that Your Snark Is Not a Boojum,” Kim Wallen, Archives of Sexual Behavior, vol. 36, no. 3, 2007, pp. 335-336. The author begins:

“I write to correct a striking inaccuracy in Puts’(2006) response to my critique (Wallen, 2006) of his review of Lloyd’s (2005) book, The Case of the Female Orgasm: Bias in the Science of Evolution, regarding the incidence of female orgasm during intercourse without…”

BONUS: Questions, questions, questions

Lloyd, author of the book that is at the center (or perhaps some other location) of the argument

The smell of macaroni [part 3]

Friday, August 22nd, 2014

A_MacaroniWhile vision did play an important role in the understanding of both the macaroni as a phenomenon and the pleasure garden as a space, to focus on vision, to the exclusion of other senses and embodiment, is to miss an important means of understanding both macaronis and pleasure gardens. We must understand the pleasure gardens and macaronis as multi-sensory. In particular, I show that olfaction was a crucial means of understanding the macaroni’s place within the pleasure gardens. Pleasure gardens were a place of sensory pleasures and dangers where one was expected to, and attempted to, cultivate one’s senses in particular ways. Macaronis were frequently described in terms of their perfumes and essences, and yet none of the extensive work on macaronis has interrogated this.”

The Macaroni’s ‘Ambrosial Essences’: Perfume, Identity and Public Space in Eighteenth-Century England. TULLETT, W. (2014), is awaiting publication in the Journal for Eighteenth-Century Studies.

Note: “The place or exact nature of the ‘Macaroni Club’, which Horace Walpole first described in February 1764, has been the subject of much speculation but has yielded no firm evidence or answers.”

Students’ backpack shoulder-slinging: Asymmetry effects

Wednesday, August 20th, 2014

Should you take sides on the debate about whether children should or should not carry their backpacks on (or mostly on) just one shoulder? This study adds fuel to one or another side of the debate:

justynaEffects of Carrying a Backpack in an Asymmetrical Manner on the Asymmetries of the Trunk and Parameters Defining Lateral Flexion of the Spine,” Justyna Drzał-Grabiec [pictured here], Sławomir Snela, Maciej Rachwał, Justyna Podgórska, Justyna Rykała, Human Factors, epub August 8, 2014. (Thanks to investigator Neil Martin for bringing this to our attention.) The authors, at Rzeszow University, Rzeszow, Poland, report:

The aim of this study was to examine changes in the body posture parameters defining asymmetry of the trunk and lateral flexion of the spine in children while carrying a backpack weighing 10% of a child’s weight…

Results: Trunk inclination shifted significantly in the opposite direction to the shoulder the backpack was carried on, and an increase in shoulder asymmetry was also found. We also observed a more pronounced right-side lateral flexion of the spine when the backpack was carried on the right shoulder and an analogous relationship for the left side.

Conclusion: The results of this study show that carrying a backpack in an asymmetrical manner negatively affects spine, even if the backpack weight constitutes 10% of the child’s weight, which has been previously recommended as a safe load for a child’s shoulders.

Here is a video of an older student carrying a backpack on one shoulder:

“… yet the world it describes is a mess”

Wednesday, August 20th, 2014

Physics may aim for simplicity, yet the world it  describes is a mess.”

That’s the start of John Cartwright’s article, “Roll Over, Bolzmann,” in the magazine Physics World. It tells the story of Tsallis entropy:

BoltzmannOur definition of entropy is expressed by one of the most famous formulae in physics, and dates back over a century to the work of the Austrian physicist Ludwig Boltzmann [pictured here] and the American chemist J Willard Gibbs. For more than 20 years, however, the Greek-born physicist Constantino Tsallis, who is based at the Brazilian Centre for Physics Research (CBPF) in Rio de Janeiro, has been arguing that entropy is in need of some refinement. The situation, according to Tsallis, is rather like Newtonian mechanics – a theory that works perfectly until speeds approach that of light, at which point Einstein’s special theory of relativity must take over. Likewise, says Tsallis, entropy – as defined by Boltzmann and Gibbs – works perfectly, but only within certain limits….

Q. How do Macaroni penguins smell?
A. Pretty bad.

Macaroni_PenguinFor example, Lindeboom [1984] estimated that 220 kg NH3-N was volatilized daily from a rookery on Subantarctic Marion Island occupied by 350000 macaroni penguins, and reported that the odor was apparent up to 10 km from the source.

More details can be found here.
