Designated (hitter) research

Sunday, October 21st, 2007

It’s nearing the end of the 2007 U.S. major league baseball season. For those who love baseball, and for those who are baffled by it, here are two research reports that everyone — baseball fan or not — will find either enlightening or not.

JeffGill_200w.jpgAt the end of the day, then, we believe that even the most apparently superficial opinions ? including those about sports ? embody and express citizens? underlying values, and so can serve as useful barometers of social and political attitudes.

So conclude the authors of the study:

The Etiology of Public Support for the Designated Hitter Rule,” Christopher Zorn and Jeff Gill,Quarterly Journal of Political Science, vol. 2, 2007, pp. 189-203. The authors explain:

Since its introduction in 1973, major league baseball?s designated hitter (DH) rule has been the subject of continuing controversy. Here, we investigate the political and socio-demographic determinants of public opinion toward the DH rule, using data from a nationwide poll conducted during September 1997. Our findings suggest that it is in fact Democrats, not Republicans, who tend to favor the DH. In addition, we find no effect for respondents? proximity to American or National League teams, though older respondents were consistently more likely to oppose the rule.

Moral Hazard and the Effects of the Designated Hitter Rule Revisited.” Brian L. Goff, William F. Shughart II and Robert D. Tollison, Economic Inquiry, October 1998, pp. 688?92.

(Thanks to investigators Robert and Sarah Duckham for bringing this to our attention.)

Hen second bests

Saturday, October 20th, 2007

Here are some runners-up in the Hopping Variation in the Perched Chicken Competition. The competition was announced in mini-AIR 2007-09. The winner will be announced in mini-AIR 2007-10. The competition called for limericks that pertain to this published study:

Ability of Laying Hens to Jump Between Perches: Individual Variation and the Effects of Perch Separation and Motivation on Behaviour,” G.B. Scott; B.O. Hughes, N.R. Lambe, and D. Waddington, British Poultry Science, vol. 40, no. 2, April 1, 1999, pp. 177-84.

hencam_200w.jpgINVESTIGATOR JOANNE LEARY:
If chickens were mathematickians
They’d calculate just like the dickens
The distance to perches
And how far their lurch is
To reach their desired positions.

INVESTIGATOR MIKE MCKINLAY:
The chicken who leaps from its perch
Lands with an incredible lurch
It looks for some food
Finds none but won?t brood,
It merely continues its search.

INVESTIGATOR ELVA SIMUNDSSON:
In the world of poultry elites
The losers of perch-jumping heats
Are sorted in pens
From Olympic class hens
and turned into fried-nugget treats

INVESTIGATOR CHRISTIAN FROSCHLIN:
A perched chicken sated and round,
Distrustfully ogled the ground:
“Why risk to be dropping
For meaningless hopping?
My plan to just sit here is sound!”

INVESTIGATOR MONICA SKIDMORE:
A chicken who jumps between perches
While hungry shows head bobs, and lurches.
But perch separations
Won’t get hen’s ovations.
One calls, while for short jumps it searches.

Investigator Mathew R Barley:
Those hens cleared a foot without puffing,
But poultrymen proved they were bluffing:
That gap is no bar,
They will jump twice as far
To avoid ending up full of stuffing.?

INVESTIGATOR DAVID MARPLES:
If you make chickens hungry and sad,
They will jump to a perch that’s less bad.
But make it too tough,
And they just have a huff,
And cluck that their keeper’s a cad.

INVESTIGATOR HERKY GOTTFRIED:
A chicken that wants to get plump
Will often be ready to jump
But one that’s well fed
Will not be misled –
It clucks but just sits on its rump.

INVESTIGATOR OLLIE ARBOGAST:
There once was a pullet named Josie,
Whose perch in the house wasn’t rosy.
She hopped up a peg
And soon laid an egg,
Because her new roost was so cozy.

Dutch Museum Hunts Elusive Crab Lice

Dutch Museum Hunts Elusive Crab Lice

AMSTERDAM, Netherlands (AP) ? A Dutch museum said Friday it is having trouble getting its hands on a parasite that just about everybody else is anxious to avoid: crabs.

schaamluis_200w.jpgThe Rotterdam Natural History Museum has appealed for somebody ? anybody ? to give it a single crab louse for its collection, amid fears they may be dying out.

The donor’s anonymity, said curator Kees Moeliker, is guaranteed.

“We have over 300,000 species represented in our collection,” he said. “Even though most of them are not on display, that doesn’t mean small, unpopular insects are less important scientifically.”

Moeliker said he began hunting in earnest for the species, also known as “pubic lice,” last year after reading an article published by British doctors in the June issue of the journal of Sexually Transmitted Infections.

The article, titled “Did the Brazilian Kill the Pubic Louse?” found that crabs rates had fallen first in women, and several years later in men in Leeds. The authors hypothesized that the bikini wax known as “The Brazilian” that removes all or most pubic hair, might be to blame.

“When the bamboo forests that the Giant Panda lives in were cut down, the bear became threatened with extinction. Pubic lice can’t live without pubic hair,” Moeliker said….

MuseumLogo.jpgSo says an October 19, 2007 Associated Press report. Kees Moeliker is the 2003 Ig Nobel Biology Prize winner (for his discovery of homosexual necrophilia in mallard ducks), and also now is the Annals of Improbable Research’s European Bureau Chief. Our European Bureau is located in the Rotterdam Natural History Museum.

Testosterone, angry faces — and dryness

Friday, October 19th, 2007

Compare the zippy wording of a press release with the dry, scientificalistic wording in the study it describes.

schultheiss.jpg

The press release is headlined “High-testosterone people reinforced by others’ anger, new study finds.” The press release says:

ANN ARBOR, Mich.?Most people don’t appreciate an angry look, but a new University of Michigan psychology study found that some people find angry expressions so rewarding that they will readily learn ways to encourage them.

The study is called “Basal testosterone moderates responses to anger faces in humans.” The study says:Wirth_Michelle.jpg

Prior research showed relationships in humans between testosterone (T) and vigilance to facial expressions of anger, which are considered signals of an impending dominance challenge. In Study 1, we used a differential implicit learning task (DILT) to investigate the degree to which subjects find anger faces reinforcing.
