Understatement of the Day

Emily Hauser is anxious (Sandy and elections).  She writes: "...I want him [Romney] to be a mensch and acknowledge that what this country needs is a second Obama term and announce that he’s throwing in the towel. And that’s not really a reasonable expectation."

You Can't Keep Vertical Farms Down

Tyler Cowen at Marginal Revolution includes a link to this piece on a vertical farm in Singapore. I comment that I don't think it's economically feasible.

Dairy and Evolution

Via Marginal Revolution, a very interesting Slate piece on the evolution of lactase-tolerance.  An excerpt:

Milk, by itself, somehow saved lives. This is odd, because milk is just food, just one source of nutrients and calories among many others. It's not medicine. But there was a time in human history when our diet and environment conspired to create conditions that mimicked those of a disease epidemic. Milk, in such circumstances, may well have performed the function of a life-saving drug.

You can't be a dairy farmer and deny evolution.

Blitzkreig, Via Horses

Brad DeLong has regular posts on the progress of WWII.   In 1942 Stalingrad was the big battle, indeed the turning point of the war.  He includes this:

"6th Army also sends back its 150,000 draft horses, as well as oxen and camels, back to the rear, to save on fodder. Motor transport and repair units are also sent back behind the Don."

The Iowa State Nearly Organic Study

Mr. Bittman discusses a 9-year Iowa State study of organic agriculture in Sunday's Times (I'm just getting caught up with my reading).

From the abstract: we conducted a field study from 2003–2011 in Iowa that included three contrasting systems varying in length of crop sequence and inputs. We compared a conventionally managed 2-yr rotation (maize-soybean) that received fertilizers and herbicides at rates comparable to those used on nearby farms with two more diverse cropping systems: a 3-yr rotation (maize-soybean-small grain + red clover) and a 4-yr rotation (maize-soybean-small grain + alfalfa-alfalfa) managed with lower synthetic N fertilizer and herbicide inputs and periodic applications of cattle manure. Grain yields, mass of harvested products, and profit in the more diverse systems were similar to, or greater than, those in the conventional system, despite reductions of agrichemical inputs. Weeds were suppressed effectively in all systems, but freshwater toxicity of the more diverse systems was two orders of magnitude lower than in the conventional system. Results of our study indicate that more diverse cropping systems can use small amounts of synthetic agrichemical inputs as powerful tools with which to tune, rather than drive, agroecosystem performance, while meeting or exceeding the performance of less diverse systems.

So it wasn't "organic"in the pure sense. And that raises a question: currently "organic" food gets a significant price premium.  Is it possible for "nearly organic" food to get a price premium? (A quick skim of the report says they didn't assume higher prices for outputs of the alternative systems.) Is it possible to rally public support for farm programs helping "nearly organic" farmers?

I renew my question from previous such studies: where is the market for the increased production of alfalfa?

Basalt Rebar

Walter Jeffries is using basalt rebar  in his butcher shop, which progresses apace.  For some reason that blows my mind, I'm not sure why. Maybe because I think of basalt as a rock, a solid, not as something which once was liquid and could be liquidified again.

See the site here.  I note the local supermarket has stanchions (upside down U's) to keep their carts nearby, and some of the stanchions have rusted where it goes into the concrete.

Gravity: There's Always a Catch

Technology Review has a piece on 3-D printing. It seems some people who try to use 3-D printing to make physical models of their fancy designs forget something.

"Sometimes, after an outlandish request—a character whose minuscule limbs simply won’t support a body, say—Carmy’s colleagues have to gently explain that different rules exist for physical product design. “We have gravity, for example,” she says."

The Importance of Crop Insurance

In the US the insurers have a video on loss adjustment.

In Ghana, Chris Blattman passes along the conclusion of an academic paper on crop insurance for those farmers.

Early Voting: the Evolution of the Ground Game

I'm down in the records as a reliable Democratic vote.  (Read The Victory Lab for an interesting take on how well the experts can track and manipulate such data.)  So usually I get a call during Election Day to be sure I've voted, perhaps a call or two before to be sure I'm planning to vote.  This year for the first time I got a call nudging me to early vote.  Virginia's rules on early voting are more restrictive than other states, though there are enough exceptions that I could perhaps fit through one of them. The advantage of early voting for the campaign is they'll know when I've voted (that's a public record), so they can scratch me off their list and focus their efforts on others.

That logic and effort is sort of reflected in this Mark Halprin piece on Obama's ground game (hat tip Volokh Conspiracy) and this Molly Ball piece in Atlantic.

Super User Boot Camp and the History of Training

There was a super-user boot camp for MIDAS last week.  Some 60 super-users were trained on it.  Apparently the Deputy Administrator was opening the session, because the website shows a picture of him, but the associated link points back to the Administrator's message of August.

I'm a bit curious as to the setup--whether this is train-the-trainer?  When I moved to the program side, the standard for training was: Washington program specialist trained state program specialist who trained the county CED's and PA's.  That's the way we trained for the System/36, though the "program specialists" were mostly the people hired out of the county office to work in DC (today's business process analysts, I think).  As time went on we became more sophisticated in training; we even did dry runs instead of just winging it in front of the audience.  With the advent of PC's and Word Perfect our materials could be a lot prettier, though perhaps not much improved in quality.

By the early 90's we were providing our presentations on floppy disks to the state people.  And then we started to train the trainers; rather than just relying on the state specialists, we'd pull in selected county people and mix up the areas.  The theory was in part to spread the training burden, in part to encourage cross-fertilization of ideas at the county level, rather than having 50 silos of county to state communication where the major cross-fertilization occurred at the state level.  I don't remember ever doing a detailed evaluation of our methods, to see whether we really did improve county operations through such training methods.

These days, with social media, and bring your own device, I'm sure there are new possibilities for improving training.
