Dust in the Hen House

Extension has a post on poultry housing options.  From personal experience I can testify to the dusty conditions in a hen house (what they categorize as a barn).

Air quality is often poorer in alternative housing systems, and this can affect health and hygiene, which is relevant not only for hen welfare but also for food safety.
The large amount of litter and the greater bird movement in alternative systems result in greater concentrations of bacteria and fungi in the air and in greater dust concentrations compared with conventional and furnished cage systems. Greater dust concentrations have been associated with more serious pulmonary lesions, typical of chronic bronchitis, in cage-free birds (Michel and Huonnic, 2003).
As you might expect they've reservations about cage systems.  Whether or not they properly weigh the tradeoffs I won't judge, but there are tradeoffs.

Good for Secret Service

Homeland Security secretary Johnson gave the Secret Service plaudits for getting the pope, the Chinese president, and the heads of state at the UN in and out of the country safely, with no bad press. 

It's nice to see big shots recognizing the work  people do.

Historical Errors

Thinkprogress has a piece where a mother who's also a historian challenges a Texas schoolbook used by her child.  From the piece:

"A Texas mother spoke out against part of McGraw-Hill’s textbook, “World Geography,” when she noticed that the language erased slavery by calling slaves “workers” and including them in the section “Patterns of Immigration.” One example of the text:
The Atlantic Slave Trade between the 1500s and 1800s brought millions of workers from Africa to the southern United States to work on agricultural plantations."
The challenge is to "workers" instead of "slaves", a challenge with which I agree.

But there's another error which passes unnoticed: "millions".

From Gilderlehrman:
 Approximately 11,863,000 Africans were shipped across the Atlantic, with a death rate during the Middle Passage reducing this number by 10-20 percent. As a result between 9.6 and 10.8 million Africans arrived in the Americas.
About 500,000 Africans were imported into what is now the U.S. between 1619 and 1807--or about 6 percent of all Africans forcibly imported into the Americas. About 70 percent arrived directly from Africa.

"Butt Dials"

I really don't understand this, perhaps because I don't use a cell phone/smart phone.

"Butt dials"

Peter Moskos links to a BBC piece on the problem of accidental 911 calls.  Judging from the article, the UK has had the same problem, except their emergency number is "999".

I understand that making an emergency call is easier than a regular one, but what I don't understand is how the butt knows to dial 911 in one country and 999 in the other?  Do people have smart butts, smart enough to know the different numbers? Never knew that.

CRISPR and Pets--Micro-pigs

Chinese scientists have used gene editing techniques to modify a small breed of pigs into "micro-pigs" according to this report.  The intent was to make the pigs smaller, therefore cheaper to raise as models for human disease.  They didn't foresee that a nice small pig would have potential as a pet.

IMHO genetic modification is like a horror movie, or Fantasia, where you see the water or other liquid coming under the door, the hero tries to keep it out, or clean it up, succeeding momentarily but ultimately failing.   (Not that I think genetic modification is a threat, per se, but it is change and some changes are mostly irresistable.)

Are Children More Civilized Than Adults?

The question of how social norms change has always fascinated me.  I've previously mentioned a book by Prof. Appiah on the subject: how duels in the West or foot-binding in China became unapproved.  He doesn't discuss, nor had I thought of this factor: children.

Children can point out hypocrisy, and lots of our norms are hypocritical.

This is triggered by a brief post on Kottke.org, where Jason writes, in partial explanation of a decrease in soda consumption in the US:
I've been a dedicated soda drinker1 since at least high school. But this summer, I started cutting back. The big reason is that my kids are getting old enough to read labels and wonder why I'm consuming so much sugar, the little blighters. "All that sugar is not good for you, right Daddy?" they would say. And they're completely right of course and I couldn't argue with them on that point, so I've been drinking a lot less of the stuff. I haven't cut it completely out of my diet but I treat it more or less like every other food or beverage I consume: everything in moderation.

Shed Tears for Managers

From a Government Executive piece on a new book on transitions
"“We were not considering management, such as procurement reform, which are not sexy or talked about on the campaign trail, just policy and politics,” Lu said. “At the White House we’re not good managers—we’re good at messaging and issuing edicts.” Future transitions should make management a higher priority, he said.

Rolling in His Grave: Mao Tse-tung

That's the only conclusion I can draw from this New Yorker piece, on a butler training school in Red China, of all places.

An excerpt:
Among China’s burgeoning population of new millionaires (their ranks have tripled since 2012, to more than 3.6 million) there is a peculiar appetite for the fusty trappings of European nobility. Chinese real-estate developments with names like Majesty Manor and Top Aristocrat package themselves as enclaves of Old World opulence, their properties complete with moats, replicas of Buckingham Palace gates, and mansions modelled after Versailles. Rolls Royce has begun offering Chinese customers chauffeur training with purchases from its seven-figure Phantom line, and Christie’s has opened a specialized agency to help Chinese buyers purchase wine estates abroad. For Chinese élites who are eager to adopt lifestyles commensurate with their massive wealth, such status symbols lend a recognizable veneer of Western-style aristocracy. (Many in the industry attribute the trend to the immense popularity of “Downton Abbey,” which has given millions of Chinese viewers a window into Edwardian upstairs-downstairs living.)

Who knew they liked Downton Abbey?

Education and Fatalities in Car Accidents

I might as well double down on my comments on this post on the differences in fatality rates based on education level, reporting on an academic study (from which I've stolen the graph).



Most of the commenters and the study itself focus on the differences in deaths among the different levels.  But what struck me is the deviation in the relationships: simply put, the rate goes down between 1995 and 2010 for all groups, all except those who didn't graduate high school.  I didn't see any explanation offered for why that group might have an increase in fatality rate.  I could guess maybe a change in drug usage--meth and oxy usage is, I believe, up particularly in rural areas, but that seems unlikely to move the trend that much. 

Chalk it down to a mystery.
