Matching is not a design or an identifying assumption. Rather, it is one of several estimators that can be use when assuming selection on observed variables or unconfoundedness (or ignorability, or conditional independence, or whatever else your particular discipline or sub-field happens to call it this week). The key to evaluating an analysis based on an assumption of selection on observed variables is a careful consideration of the set of conditioning variables used in the analysis to deal with the problem of non-random selection into treatment. Estimator choice, e.g. matching versus linear regression versus inverse propensity weighting, is not unimportant, and can be very important for specific data generating processes, but what really matters in general is the set of conditioning variables.
The World War II Soviet operation to seize Romania in September 1944 ended up costing the Red Army 46,783 dead and 171,426 wounded, along with 2,200 tanks and 528 aircraft destroyed. As such it was the least costly of all the strategic operations launched by the Kremlin that year. In comparison, the forces of the British Commonwealth engaged in northwest Europe didn't sustain that number of casualties during the entire period from D-Day to V-E Day.This fact, from a Strategy and Tactics magazine email (board wargames were one of my youthful hobbies) does a nice job of illustrating both cross-national differences in military effectiveness during WW2 but also, how successful the US has been at using capital goods to reduce casualties. For example, a site called casualties.org lists US military fatalities for the entire Iraq war as 4794. While one would obviously prefer zero (and arguably, one might also prefer that the Iraq war had been skipped altogether in favor of just taking out Saddam and his sons with missiles or drones) casualties, the orders-of-magnitude change is worthy of note and, I think, insufficiently remarked upon.
“Drive” is somber, slick and earnest, and also a prisoner of its own emptiness, substituting moods for emotions and borrowed style for real audacity.I would disagree with him about only one thing, which is the innocence of the character played by Carey Mulligan. Her character is guilty through inaction. She is written and acted to have no agency of her own - she just responds to the actions of others - as well as a taste for rough guys. I'd say that's guilty enough.
NASA says the satellite is likely to begin re-entry on September 23, 2011, give or take a day. Hurtling at five miles (eight kilometers) per second, they say it could land anywhere between 57 degrees N. latitude and 57 degrees S. latitude – basically, most of the populated world.That's a really imprecise estimate! As the article notes, it basically leaves out only Santa and penguins. I hope this prediction did not cost very much.
More significant may be the introduction of practical strategies for cultivating creativity and consciousness within the classroom. The Contemplative Practice Fellowship program of the American Council of Learned Societies, launched in 1997, has supported coursework to integrate meditation and a range of contemplative modalities at over 80 institutions—including Amherst, Vassar, Brown, Smith, Wellesley, Columbia, Harvard, Yale, Bryn Mawr, Michigan, UMass, and UC Berkeley—might be noted as a landmark development along these lines. Extending from this initiative is an expanded epistemological continuum that includes silent meditation, contemplative approaches to reading, writing, movement, nature awareness practices, and creativity in and beyond the arts. When integrated with community engagement, diversity studies, and rigorous intellectual engagement across a variety of fields, this continuum is unique in bridging interior and exterior engagement. Creativity and Consciousness Studies thus offers today’s students the best of both conventional pedagogical approaches and strategies at the cutting-edge of educational thought.When it comes to expanded epistemological continuums (continuii?) I say: Go Blue!
There are too many redheads in relation to demand,' [sperm bank director] Mr Schou told the Danish newspaper Ekstra Bladet. 'I do not think you chose a redhead, unless the partner - for example, the sterile male - has red hair, or because the lone woman has a preference for redheads.
'And that's perhaps not so many, especially in the latter case.'As for me, I like redheads so much that I married one.
"I think there was a handful of plays that could have swung this game in either direction, some of which were self-inflicted and some of which maybe I don't agree with the call." — UW coach Steve Sarkisian.Exactly, and Sark is being very kind about the calls, both of which were blatantly wrong enough that the on-air announcers for ABC criticized them, which is unusual.
This is the kind of stuff that makes people cynical about politics, but if you’re not cynical about politics, it’s only because you don’t actually know anything about politics.What a dirty business. And yet many people hold up politicians as objects of admiration.
A physicist, a chemist and an economist are stranded on an island, with nothing to eat. A can of soup washes ashore. The physicist says, "Lets smash the can open with a rock." The chemist says, "Lets build a fire and heat the can first." The economist says, "Lets assume that we have a can-opener..."Seems like something every student of economics should know, if only because one sometimes hears references to it in economics talks and even in popular culture. And, of course, also because it makes a useful substantive point about economists.
If you are failing this course, do not make sly little suggestions about what you might do to earn a passing grade. You are failing the course — why should I think your performance would be better in any other areas? Besides, I'm too old to care.Though, to be honest, I think this type of sly offer never actually happens. Or maybe it is just that I always taught the honors students at UWO, and never the general students.
I have received a missive from some LSU official informing me that, as a holder of LSU football season tickets, I am considered an athletic booster. One of the many things I am forbidden to do as an athletic booster is to provide to any enrolled student athlete any academic assistance, including tutoring, editing of papers, assistance in completing coursework, or the use of a computer.Though the Angry Professor disagrees, I'll stand by my view in the comments that the university wants faculty to help its "student athletes" but wants to be sure that the legal liability for such actions falls on individual faculty members and not on the central administration of the athletic department.
