Birth order, familial environment, and ‘intelligence’.

There’s another piece in the New York Times today about how birth order and family dynamics might play a role in “intelligence” (as measured by IQ — an imperfect measure at best). This is a follow up to their earlier story about research reported in Science and Intelligence that claims, based on research on male Norwegian conscripts, that “social rank” in a family accounts for a “small but significant” difference in IQ scores. (Zuska reminds us of the dangers of drawing too strong conclusions from limited data.)
Today’s Times piece seems to be a round-up of anecdata of the sort that readers would find engaging as they quaff their coffee. However, I think the anecdata suggest ways that the system under study is complicated.

And while we’re admitting you to college, let’s throw in the Ph.D. program too!

Another article from Inside Higher Ed that caught my eye:

The chancellor of the City University of New York [Matthew Goldstein] floated a unique approach this week to dealing with the long lamented problem of low enrollments in the sciences: Offer promising students conditional acceptances to top Ph.D. programs in science, technology, engineering and math (the so-called STEM fields) as they start college. …
In a speech Monday, Goldstein envisioned a national effort in which students identified for their aptitude in middle school would subsequently benefit from academic enrichment programs that their own local high schools might not be able to provide (The chancellor described the proposed program as one that could have a particularly strong impact on increasing woefully low minority enrollments in the STEM fields).
Upon entering college, students would be offered a spot in a top Ph.D. science or math program, provided they meet certain performance requirements throughout their undergraduate years.
“It sends a very strong statement to students who have not necessarily had the encouragement … that very elite places genuinely believe in them and, at an early age, they are prepared to make an investment to serve as an incentive for those students to continue to do very good work,” Goldstein said.

Some of my initial reactions to this proposal:

What ought to be driving college admissions decisions?

Recently Inside Higher Ed had an article about a study (PDF here) coming out of the University of California on the predictive power of the SAT with respect to grades in college courses. The study, by Saul Geiser and Maria Veronica Santelices at the UC-Berkeley Center for Studies in Higher Education, followed the performance (which is to say, grades) of students at all UC campuses for four years and found that “high school grades are consistently the strongest predictor of any factor of success through four years in college”. Indeed, the study found high school grades a stronger predictor of grades past the first year.
The SAT turned out to be not such a great predictor of college grades, but a dandy predictor of socioeconomic status of the kids taking the SAT.
What interests me about this story is not the perennial debate about whether the SAT tells admissions officers anything useful about applicants, but the larger question of what admissions officers — and folks in society at large — imagine should be the guiding principle in deciding who ought to win the competition for scarce spaces in a college class.

Department of Homeland Security and academic labs.

In the June 4, 2007 issue of Chemical & Engineering News (which is behind a paywall accessible only to ACS members and those with institutional subscriptions, I’m afraid) there’s an article on how college and university labs may be impacted by the interim final regulation on chemical security issued recently by the Department of Homeland Security.
In a nutshell, that impact looks like it could involve thousands of hours and hundreds of thousands of dollars for a single university to comply with the rules, even if the chemicals they use fall into those specified by DHS as being at the lowest level of risk. As you can imagine, the colleges and universities are kind of freaked out.

Is it arrogant to want to use our scientific knowledge?

Perhaps you heard Steve Inskeep’s interview with NASA administrator Michael Griffin on Morning Edition this morning. Perhaps you also are trying to tease out the logical consequences of this statement he made about climate change:

I have no doubt that … a trend of global warming exists. I am not sure that it is fair to say that it is a problem we must wrestle with. To assume that it is a problem is to assume that the state of Earth’s climate today is the optimal climate, the best climate that we could have or ever have had and that we need to take steps to make sure that it doesn’t change. First of all, I don’t think it’s within the power of human beings to assure that the climate does not change, as millions of years of history have shown. And second of all, I guess I would ask which human beings — where and when — are to be accorded the privilege of deciding that this particular climate that we have right here today, right now is the best climate for all other human beings. I think that’s a rather arrogant position for people to take.

Independent confirmation and open inquiry (investigation? examination?): Purdue University and the Rusi Taleyarkhan case.

My recent post on the feasibility (or not) of professionalizing peer review, and of trying to make replication of new results part of the process, prompted quite a discussion in the comments. Lots of people noted that replication is hard (and indeed, this is something I’ve noted before), and few were convinced that full-time reviewers would have the expertise or the objectivity to do a better job at reviewing scientific manuscripts than the reviewers working under the existing system.
To the extent that building a body of reliable scientific knowledge matters, though, we have to take a hard look at the existing system and ask whether it’s doing the job. Do the institutional structures in which scientific work is conducted encourage a reasonable level of skepticism and objectivity? Is reproducibility as important in practice as it is in the scientist’s imagination of the endeavor? And is this a milieu where scientists hold each other accountable for honesty, or where the assumption is that everyone lies?

The allegations around nuclear engineer Rusi Taleyarkhan — and Purdue University’s responses to these allegations — provide vivid illustrations of the sorts of problems a good system should minimize. The larger question is whether they are problems that are minimized by the current institutional structures.

What they said at the panel on the future of higher education.

Since many of you were kind enough to suggest questions to ask of Margaret Spellings at SJSU’s Founders Day “The Future of Higher Education” panel last Friday, I thought I should report back on that session.
First, the bad (but utterly predictable) news: while Margaret Spellings gave the keynote address, she didn’t stick around for the panel discussion afterwards — so she wasn’t there for the question and answer period. However, the panel of experts certainly had something to say about the Spellings Commission report on higher education.

Separating the public and private spheres.


Depending on your blog reading habits, you may already have heard the news that feels almost like cosmic justice that a law firm has rescinded an offer of employment from a third year law student whose online activities the firm found troubling. The linked posts will give you some flavor for those activities (as will this post), so I’m not going to go into the gory details here. However, I wanted to say a few words about this comment Amanda Marcotte made on Sheezlebub’s post on the matter:

While it couldn’t have happened to a nicer guy, I simply have to voice my unease with the politics of personal destruction, even when done for the right cause. Getting people fired is the right’s strategy. (I know.) Scalp-collecting bothers me to no end. Granted, we didn’t do anything to get him fired, but needless to say, I have to protest any and all attempts in the future to separate a person from his job because of his opinions in a non-work capacity.

(Bold emphasis added.)

You may recall that Amanda left her job with the Edwards campaign because Bill Donohue’s Catholic League decided to make Amanda’s personal views into a big issue for Edwards. (Arguably, Donohue did this by misrepresenting her views, which strikes me as an ethical violation of the bearing-false-witness variety, but I’m just giving you the background for Amanda’s comment.)

Anyway, the issue I want to examine is the separation between work and non-work conduct and opinions, especially as they are manifested on the internet.

Homeschooling and chemistry.

The April 16 issue of Chemical & Engineering News has an interesting article about homeschooling families looking for chemistry curricula. (You need an individual or institutional subscription to view the article; it might be worth checking with your local library.)
I’m far from an expert on homeschooling (as we’re availing ourselves of the public schools), but I’m fascinated by the ways some of the families featured in the article are piecing together what they need for their kids.
