Few times as a kid did I wish for a teacher to ask, What I Did on my Summer Vacation? The school year beginning in 1971 would have been one of them. I recently wrote a bit about one day that summer at one of my other venues: TheObjectAtHand: Balloon Memory
Conservative. Liberal. We act as if we know what these labels mean. Conservatives are traditionalists, fiscally opposed to anything that smacks of gambling, private, often religious, and pedantic on what they consider “appropriate” in either government or personal conduct. Liberals, on the other hand, are often taken for progressive, willing to spend social capital to repair perceived problems, tolerant, agnostic if not atheist, and overly-concerned with a definition of justice that ought to be all-encompassing rather than what they perceive as sinecure for the privileged. Well. Over on Facebook I posted a brief quote (my own) to boil down the actual underlying distinctions. Conservatives are those who don’t like what other people are doing, Liberals are those who don’t like what other people are doing to other people. It was meant to be taken as humorous. But I’m not being entirely flip here. When you look at it, and try to define the common factor in much that passes for conservative posteuring—of any country, any background, anywhere—it always comes down to one group trying to stop another group from Doing Things We Don’t Approve. I heard a news report this morning (on NPR—I unabashedly don’t pay attention to any other news source, I find them all utterly biased) from Pakistan about the university scene there, and one bit caught my attention—at a campus in Punjabi, conservative students who find men and women sitting too close together interfere and move them apart. At a game of Truth or Dare, conservative students pulled participants out and beat them. How does this apply here? Well, here’s a clip from P.Z. Meyers’ Pharyngula to illustrate: Rising Sun School in Maryland has the standard default take-it-for-granted attitude that Christianity is just fine — there’s the usual well-funded and usually teacher-promoted evangelical groups, like the Fellowship of Christian Athletes — and when one student tried to form a club for non-religious students…well, you can guess what happened.
Now a new study published in Pediatrics, the journal of the American Academy of Pediatrics, links pesticide use with the rise in ADHD disorders among children. The study's authors examined data on over 1,100 children, and determined that elevated levels of pesticide metabolites in the urine was associated with a diagnosis of ADHD. In fact, children with levels higher than the median of the most commonly detected metabolite (known as dimethyl thiophosphate), were twice as likely to be diagnosed as ADHD compared with children that had undetectable levels of the metabolite. The elevated risk factor remained even after controlling for confounding variables like gender, age, race/ethnicity, poverty/income ratio and others. The pesticides studied belong to a class of compounds known as organophosphates. Time explains:
[Study author Maryse] Bouchard's analysis is the first to home in on organophosphate pesticides as a potential contributor to ADHD in young children. But the author stresses that her study uncovers only an association, not a direct causal link between pesticide exposure and the developmental condition. There is evidence, however, that the mechanism of the link may be worth studying further: organophosphates are known to cause damage to the nerve connections in the brain — that's how they kill agricultural pests, after all. The chemical works by disrupting a specific neurotransmitter, acetylcholinesterase, a defect that has been implicated in children diagnosed with ADHD. In animal models, exposure to the pesticides has resulted in hyperactivity and cognitive deficits as well.
