As Steven Taylor notes in the latest Toast-O-Meter, there’s a primary to be held this Tuesday in Mississippi and three other Southern states. Democratic frontrunner and presumptive nominee John Kerry will be campaigning in Jackson tomorrow at a black church and Tougaloo College.

Steven Taylor, prompted by the Invisible Adjunct, observes that the appropriateness of lecturing versus using a seminar format is largely determined by three factors:

1) the level of the course (e.g., intro, advanced undergrad, grad), 2) the subject matter, and 3) the size of the class.

I’d broadly agree with Steven. All three of these factors are highly correlated; relatively straightforward subject matter is generally taught at an introductory level in large classes, while more complex subject matter usually involves small classes taught at an advanced level. The exceptions—notably the “honors seminar” version of intro—work because there’s an underlying assumption that the students in the course are already familiar with most of the material that they would have learned in the non-honors course, thus the course is no longer a true “intro” course.

Starting this summer, Mississippi’s getting a new area code—769—which will overlay the 601 area code in central Mississippi. Amazingly, Mississippi only had one area code until 1997. (Everything you’d ever want to know about area codes is here.)

The 2003 Chairman’s Letter to the shareholders of Berkshire Hathaway was released this morning, and Warren Buffett gets in a couple of subtle digs at the Bush administration. The best one was this one on page 19, regarding the opening of a new Nebraska Furniture Mart (NFM) store in Kansas City:

“Victory,” President Kennedy told us after the Bay of Pigs disaster, “has a thousand fathers, but defeat is an orphan.” At NFM, we knew we had a winner a month after the boffo opening in Kansas City, when our new store attracted an unexpected paternity claim. A speaker there, referring to the Blumkin family [the founders of NFM], asserted, “they had enough confidence and the policies of the Administration were working such that they were able to provide work for 1,000 of our fellow citizens.” The proud papa at the podium? President George W. Bush.
