Females and Eating Disorders

Friday, May 3rd, 2013

Females are four to 10 times more likely than males to have an eating disorder — presumably because of social pressure to be thin.

But female rats are also much more likely than male rats to have an eating disorder:

Klump and colleagues ran a feeding experiment with 30 female and 30 male rats over a two-week period, replacing the rodents’ food pellets periodically with vanilla frosting. They found that the rate of binge eating “proneness” (i.e., the tendency to consume the highest amount of frosting across all feeding tests) was up to six times higher in female as compared to male rats.

The Pentagon Wars

I haven’t watched The Pentagon Wars, but the key segment, describing the evolution of the Bradley Fighting Vehicle says it all, I suspect:

Why Many in China Hate Iron Man 3′s Chinese Version

Thursday, May 2nd, 2013

The latest Iron Man movie has a second version with Chinese footage badly edited in for the Chinese market — only the Chinese seem to hate it:

In Dr. Wu’s office, you can see Tony’s Iron Man on a TV screen, surrounded by Chinese children and what looks like… Dr. Wu. The good doctor then calls Tony, but J.A.R.V.I.S., the A.I. butler, answers. It’s worth noting that in even in the subtitled version, there are no subtitles in this sequence; J.A.R.V.I.S. speaks in Mandarin Chinese. While speaking with J.A.R.V.I.S., Dr. Wu actually says in Chinese, “Tony doesn’t have to do this alone — China can help.”

There’s also this extra long shot of Dr. Wu awkwardly pouring a glass of Yili brand Chinese milk. But it’s pure product placement. Before the movie starts, there are two China specific ads: One of them is a Chinese milk commercial that, as The Hollywood Reporter points out, asks, “What does Iron Man rely on to revitalize his energy?” (The answer is a Yili milk drink.) The second commercial is for a Chinese manufacturer of tractors and cranes.

Will Obamacare work?

A new study out of Oregon shows Medicaid’s limits:

In its second-year results, the Oregon Health Insurance Experiment, which randomly selected 10,000 people in Oregon to get Medicaid (only about 6,300 actually got the benefit), and then compared them with a randomly selected control group, found that those who got Medicaid did not on average have healthier blood pressure, cholesterol levels, or diabetic blood pressure control than those who did not get Medicaid. Those with Medicaid did see some reduction in out of pocket health expenses. They were also less likely to be diagnosed with depression.

The Medicaid recipients also ended up utilizing a lot more health care — care that has to be paid for — than those who didn’t get coverage. But they didn’t use the emergency room any less than the control group.

How is this being presented in the media? A bit differently…

Filthy Thirteen

Thursday, May 2nd, 2013

The Dirty Dozen were fictional, but the Filthy Thirteen were real:

The “Thirteen” was an unofficial unit (in fact consisting of up to 18 men) within the 506th Parachute Infantry Regiment, 101st Airborne Division. It was parachuted into France hours before the D-Day landings to take and hold a bridge over the Douve river, in a bid to prevent German reinforcements from moving into Normandy.

The group derived its nickname from the fact that they showered just once a week and never washed their uniforms — as well as from their insubordinate attitude to authority. “We were absolutely undisciplined,” McNiece recalled. “We did not greet the officers and we did not speak to them by saying the traditional ‘Sir’. We used to call them by their nicknames.” Following the example of McNiece, whose mother was a Choctaw Indian, the men prepared for their mission by shaving their heads into Mohican haircuts and smearing their faces with war paint.

Jake McNiece and Filthy Thirteen

Shortly after midnight on June 6 1944, McNiece and his men parachuted behind enemy lines. By the time dawn broke, they had destroyed two bridges and had taken up positions on the bridge over the Douve. They held it against German counter-attack for three days until the structure was bombed, apparently in error, by the US Air Force. “I was submerged by anger,” McNiece recalled. “We had kept this bridge despite all opposition! And it’s our aircraft which bombed it!”

McNiece and his men subsequently joined the main invasion, and on one occasion were on the winning side of a firefight that saw 700 German soldiers killed in just 20 minutes. Paratroopers did not take prisoners, as he later explained.

McNiece believed that the group had been selected because their task was regarded as a “suicide mission” and, as notorious troublemakers, the men were seen as expendable. “The average lifetime of a paratrooper was one and a half jumps,” he recalled. “They gave you one day’s food supply when you left the plane, and they figured you wouldn’t eat all of that.”

By the time McNiece returned to Britain after 36 days of fighting, all but three members of his unit had lost their lives. Yet there were some compensations: the survivors “got two months’ wages plus everything we stole in France”.

Making Mordor’s Economy Work

Wednesday, May 1st, 2013

Making Mordor’s economy work takes some effort, if you assume the ashen wasteland produces no food yet feeds an army:

If Mordor was trading something, then we imagine that this would be swords. Sauron had both mines and forges, and so supply should not have been an issue. A medieval sword cost around 6d (6 pence) each. We got in touch with expert Hector Cole, master arrowsmith and archaeological ironworker, who gave us some ideas of medieval sword manufacture.

Six smiths produce ten swords per day, 6d (6 pence) per sword, 60d revenue per day.

Bearing in mind that within Mordor itself there isn’t an economy; it’s a command system governed by Sauron and his Nazgul. So mining and manufacture costs aren’t monetary, and all 60d can be spent on other things. Like…

Food. Feeding an army isn’t easy. One option for mass consupmtion is pig.

A hog roast can feed about 100 at a sitting. Assuming 3 meals per day this is 33 orcs per pig. A medieval pig cost 2 shilling (24 pence) each. So 100 orcs can be fed for 72d per day.

So to keep 500 orcs fighting, around 35 orcs are needed to be smithing, and about 1 orc smelting.

Thus for Mordor’s economy to work, constant wars would be needed to keep up the demand for weapons, so that Mordor could trade them for food. This raises the question of how moral it would be for Sauron not to start wars. Due to the requirements of smithing and smelting, about 7% of orcs would be involved in ‘civilian’ roles. When considering firewood, building, and particularly mining, this figure would become much higher.

LASD Range

Wednesday, May 1st, 2013

This 1936 footage from the Los Angeles (County) Sheriff’s Department’s Biscailuz Range struck me as terribly old-timey — especially with the ragtime soundtrack — until they got to the Combat Range:

They were scoring named courses of fire, based on real-life scenarios, in points per second, long before IPSC formed in the 1970s.
