Doing something for non-traditional students

A few years ago I did a stint as an instructor at a large state school (fun work, terrible pay). Most semesters I taught at least one night course which meant lots of non-traditional students. They always impressed the hell out of me. Most were working full time jobs, many had kids to take care of, but somehow they always were the ones who got all their homework in, showed up for study sessions and managed to maintain the best attitudes.

I always felt that the university was not serving these students well, that we should have been finding ways to work around their schedules to make their lives easier and the path to graduation quicker. With that in mind, I liked a lot of what I heard in this NPR report on Western Governors University, a nonprofit online school designed to help adult students finish college.

Shackleford can also keep her costs down by finishing her coursework early. The average time to get a degree at Western Governors is much shorter than at a typical school, where students have to put in a set amount of "seat time."

But the truly unusual thing about this computer-driven system is that it provides a lot of one-on-one attention. Throughout her time at Western Governors, Shackleford will have her own personal student mentor — a combination guidance counselor, career coach and best buddy.

Shackleford has never met her mentor in the flesh, even though she lives about 90 minutes away, just north of Indianapolis. Her name is Stormi Brake, and she also works out of her home office, in a house filled with kids and pets.

When I show up for a visit, Brake is wearing a headset and talking on the phone with one of her 90 students. She is organized and energetic, jumping from student to student to head off any problems. She tracks their progress on a computer dashboard the school uses. She shows me that students who are completing required tasks on schedule show up in green, while those who are behind show up in red, a sign that the mentor needs to get in touch.

Brake has a strong background in science and teaching, but her job is to make sure her students get their degree. Students with questions about course content can turn to another kind of mentor — a course mentor — who's considered an expert on the subject.

Cash for Citations

Mark sent me this piece entitled Cash for Citations?. The title was a bit misleading when you click though and read the actual offer:

An astronomer at King Abdulaziz University (KAU) in Jeddah, Saudi Arabia, was offering him a contract for an adjunct professorship that would pay $72,000 a year. Kirshner, an astrophysicist at Harvard University, would be expected to supervise a research group at KAU and spend a week or two a year on KAU’s campus, but that requirement was flexible, the person making the offer wrote in the e-mail.

I am actually not sure that this rises to the level of a "scam" by modern standards.  The professor would, after all, work with the students at KAU and be residential for at least part of the year.  Sure, the salary is a bit high for two weeks worth of work but access to a top researcher can be worth a lot if he contributed remotely.  To rise to the level of an actual scam, the flexible requirement would have to be negotiable to no duties.

Now, the concern is that the astronomer would have to list the KAU affiliation on all of their papers.  On the other hand, if they are a salaried adjunct professor then that would actually be pretty normal.  Several of my colleagues have positions cobbled together from multiple places and the requisite need to list multiple affiliations.

The real issue is the ability of universities to purchase reputations.  It has long been true that extremely gifted and creative researchers have better employment options at least partially because of the prestige they bring to the hiring institution.  In a world with flexible work locations (consider MITx), these issues are likely to become larger over time.

But the idea of "cash for citations" is really a salary for research productivity.  The real question is how residential does a professor need to be to count as affiliated.

The sum of all fears = 183

Seeing the world from other perspectives is a good way to start the new year. With that in mind you should pony up the dollar for a download of this episode of This American Life. All its segments were strong, but for me the most affecting was the second act. It revolves around a reading from a book by a developmentally disabled man named Michael Bernard Loggins (published with the help of a remarkable arts program called Creativity Explored).

The book consists of a list of fears, in no apparent order, ranging from the trivial (needles) to the profound (a mother dying). The fears are specific and provide distinct glimpses into Michael's life, but they're universal at the same time; though the details may be different, Michael's fears are our fears.

This really is a powerful piece of writing, beautifully presented by This American Life and actor Tom Wright. You should definitely take the time to check it out and perhaps make a small contribution to TAL or Creativity Explored.

That's also a good way to start the new year.

Yes, another talking baby video, now with informed commentary

This is actually the first half of the conversation. They both come from a blog called Twin Mama Rama and they've generated quite a bit of discussion. I found these two particularly interesting:

Hope Dickinson, MS, CCC-SLP, coordinator of the Speech-Language Pathology Services at Children’s Hospital Boston at Waltham.

These two are babbling, specifically they’re demonstrating a behavior known as “reduplicated babbling,” because the sounds used are repeated, which you can hear in their use of “da-da-da.” In a more informal way, I guess I would describe it as turn-taking with babbling, or conversational babbling.

Play talk is a healthy way for kids to develop language skills

...

It really demonstrates how very young children communicate and know how a conversation works, even before they have the words to use. They will eventually begin to replace the babbling strings with words. If you listen closely, you’ll even hear a couple of words: One says “mama” when looking at the camera, and one or both say “up” more than once when picking up a foot.

One thing they are using wonderfully is turn taking, as in first one “talks” and then pauses and the other responds. They are also imitating the various intonations we use in conversation and speaking. There is fantastic rise and fall to their pitch and tones. Sentences or exclamations end loudly and emphatically, and there is also some questioning (rising) intonation. They are using gestures to supplement their talking, much like adults do. Their body distance is even very appropriate for most Americans; not too close, but not too far either.

And from the New York Times:

“Some people believe twins have the ability to generate their own detailed language, a twin language, but it doesn’t seem to be true in terms of a fully developed language system,’’ said Stephen Camarata, professor of hearing and speech sciences at Vanderbilt University School of Medicine. “They are going back and forth and enjoying each other’s company, but they aren’t saying anything specific like ‘Hey, Mom’s videotaping us. Look at her hair.’ “

...

Dr. Camarata says the video is rich with examples of how children develop language. It’s filled with canonical babbling that sounds like speech because it uses vowels, consonants and syllables to mimic words. Although most healthy babies go through the same phase of language development, most of the time the conversation is one-sided because they are interacting primarily with parents or older siblings. What’s special about the twins’ exchange, he notes, is that each baby has a peer with whom to practice language.

“The thing that is remarkable is that they both have this intonation pattern,’’ he said. “It sounds like they are speaking, making a statement, asking a question. They are using those broader markers we use in language.”

He says it’s possible that the twins are re-enacting conversations they’ve witnessed in the family kitchen.

“Children are very clever at watching and learning from adults,’’ said Dr. Camarata. “You wonder if there hasn’t been a conversation between the husband and wife or other people in the kitchen that they are mimicking. The intonation patterns were almost certainly learned from the parents.”

Dr. Camarata said he finds the video particularly delightful given that he often works with children who have delayed speech as a result of autism or another disability. He said he hopes parents who see the video will be reminded to celebrate the amazing developmental milestones of their own children.

“Here are these children interacting with each other in a very spontaneous and unguided way, and there are a lot of rich things going on that are really cool,’’ he said. “You wonder in this day and age of people programming their child’s activities if we’re losing a little bit of that. I worry that we’re not looking for and celebrating these kinds of spontaneous things that our toddlers do that are really exciting and fun.”

A quote from Coase

A nice quote from Ronald Coase:

If you torture the data long enough, it will confess.

While this comment can be taken too far and exploratory data analysis is interesting, it is a good warning to medical (and other researchers) not to over-interpret data.  Of course, this presumes that decisions are being driven by data and not based on expectations derived directly from a theoretical construct.

The world is a strange place and our minds seem to be pretty poor at "guessing" the correct answers.  

The scandal isn't that the New York Times is one of our worst papers; the scandal is that it's one of our best papers

In yesterday's NYT, Rachel Donadio had a report on Italy that included this sentence:

Germany has adamantly opposed what it sees as rewarding the bad behavior of southern rim countries like Italy, Greece, Spain and Portugal, which amassed high public debts and where tax evasion is rampant.

Except, of course, they didn't. Dean Baker (who first caught this) debunks:

Actually, of this group only Greece was consistently experiencing a rise in its debt to GDP ratio. In Portugal there was some increase in the debt to GDP ratio in the years prior to the recession, but Italy's debt to GDP ratio actually had been trending downward since 2000. Spain was running budget surpluses and had a considerably lower debt to GDP ratio than Germany.

It's not just that the NYT didn't bother to check these facts; it's that they had been debunked repeatedly in numerous places including this column printed less than a month ago in, you guessed it, the New York Times.

And Donadio is not some stringer who happened to stumble in the door. According to her NYT bio:

Rachel Donadio has been Rome Bureau Chief of The New York Times since September 2008, responsible for Italy, the Vatican and the broader southern Mediterranean.

In normal times, you would expect someone like the Rome Bureau Chief to be up on the details of what is arguably the biggest European story since the fall of the Berlin Wall. These are not, however, normal times for journalism. Standards (particularly those regarding accuracy) have fallen while journalists have (with very few exceptions) developed a disturbing herd mentality.

It's bad when journalists stop checking their own and each others' facts. It's also bad when journalists largely stop thinking independently and simply converge on a few standard narrative.

But when these two things happen together... that's catastrophic.

Adam Smith

At one point I used to be a huge advocate for re-examining Adam Smith's theories in the wealth of nations.  I was perplexed at how the words in the text did not seem to match the theories derived from it.  In particular, it seemed that nobody paid a lot of attention to his concerns with the actions of corporations.  I was reminded of this hobby of my youth will reading a comment by Dan Hirschman in Jodi Begg's blog:

Second, and more critically, be careful with Smith! Do you read historian of economic thought Gavin Kennedy’s blog, Adam Smith’s Lost Legacy? Kennedy devotes most of the blog to trying to fight the abuse of the idea that Adam Smith had some ‘theory of the invisible hand’. Kennedy has an excellent paper on the metaphor and how it became a myth (mostly blaming Samuelson’s influential textbook), Adam Smith and the Invisible Hand: From Metaphor to Myth. Long story short, that metaphor comes in the middle of the Wealth of Nations, and refers specifically to merchants who (because they are risk-averse) put their money in lower-yielding, but less risky, domestic investments and thus unintentionally stimulate local commerce. The “invisible hand” simply refers to an unintended consequence, not to some overarching thesis that self-interest leads to socially beneficial outcomes (a position held by an earlier author, Mandeville, and that Smith and his contemporaries ridiculed). For example, Smith himself lists 60 ways in which the government ought to intervene to produce better outcomes, from providing public education to regulating bank money creation. Smith also distrusted merchants, and thought they would (acting on their self-interest) readily conspire against the public (hence why he especially disliked trusts and large corporations, see Emma Rothschild’s Economic Sentiments: Adam Smith, Condorcet and the Enlightenment).

One of the interesting features of Adam Smith was how he focused on local and responsive government.  In a time with a lot less mobility, it made sense to pay close attention to local politics.  He had an excellent example of how lamp lighting in London was a public good, but that it would likely be done less well if it was done by a higher level of government than the city.

So I often get confused when he is cited by modern neo-conservatives.  The main thrust of the book seems to suggest a decentralized mixed economy rather than a scene out of an Ayn Rand novel.  

You have to wonder what they're thinking

Those of you with a low tolerance for cute might want to give this one a pass, but if you've got any interest in developmental linguistics, this exchange between two seventeen-month-olds is fascinating. Check out how they've picked up all the major non-verbal aspects of conversation.

Hulu slipped the last couple of episodes in under cover of darkness for unusually brief runs. You can still catch them if you hurry.

I think we also need to page Mark Palko

Today's new patent is from Apple, US patent #8,082,523.  It is best described as:

In other words, anything you’d recognize as a smartphone seems to be covered.

Matthew Yglesias asks the smart question:

The issue is that there's just no sound public interest case for granting monopolies over certain features to the first-to-market firms in this industry. Apple has already gained a very large competitive advantage from the fact that they were the first people to deploy a working touchscreen smartphone and even without patents clearly has a strong financial need to continue investing in improving its product lest lower-margin Android-powered phones eat away at its profits.

But the general trend seems worrisome.  Not only does it vastly increase business complexity (searching the patent office for thousands of potentially applicable patents), but it stifles innovation by making new entry into the smartphone field more difficult.

Mark?  

Does strong government help?

The comment thread on this piece is well worth reading.  In the piece, itself, Noah Smith is pointing out a possible reason for people to adhere to libertarianism -- the concern over the state protecting people from small group actions.  While this is not the only issue with this creed, I do want to look at it another way.

Why did primitive cultures lose to organized cultures?  It is pretty clear, for example, that the Gauls had a much less intrusive government than the Romans.  They had a lot of brave fighters and a fairly free society (as ancient world societies went).  While certainly a bit romanticized in literature, it is clear from reading Julius Caesar's accounts of his wars that strong central government was notably absent from the Gauls.

So why were they overrun by a high-tax society with a strong central government?

It is equally interesting to ask questions like why the residents of the American West sought statehood.  After all, did they not have a much freer society outside of the United States?

Or why do people seem to suffer so badly in failed states, which also have a lack of strong central government?

I think that these practical concerns need to be addressed.  A lot of what the state does is either protective (banning force and fraud) of individual citizens, a vehicle to allow disputes to be settled (the courts), acting as an insurance company for risks that are hard to use markets for, providing public goods, and mutual defense.  Perhaps the goal of government should be effective government and not minimalist government.

I wonder if libertarianism thrives because most of us have not seen a failed state in the first world?  People have a lot of mobility (if they are rich) and so there is less of a sense of how the government helps make a society function.

Introducing the Ddulites

I've got a new coinage I'll be referring to quite a bit in some upcoming posts so I thought I'd give it a link of its own rather than bringing it out in the middle of a longer post. (since the longer the post, the greater the chance of my saying something I'd just as well forget. This way I can always link back to this nice, short, neutral post.)


Ddulite (from Luddite):

A preference for higher tech solutions even in cases where lower tech alternatives have greater and more appropriate functionality; a person of ddulite tendencies.

Though Ddulites are the opposite of Luddites with respect to attitudes toward technology, they occupy more or less the same point with respect to functionality.

Is there an economist is the house? Casey Mulligan edition

After Christmas dinner, I did some web surfing and came across the following from Noah Smith:

Two posts back, I explained why the "Great Vacation" idea doesn't pass the smell test. If U.S. unemployment had been caused by a negative shock to labor supply, we should have expected to see an increase in real wages.

Casey Mulligan, one of the leading proponents of the Great Vacation story, responded on his blog:

A number of bloggers have recently discovered real wages as a labor market indicator. They are at least 3 years late to the party.

Three years ago I blogged about the effect of labor supply on real wages;

I noted how real wages had risen since 2007, and predicted that they would begin to decline in 2010.

I have continued to update this work, eg here, and here. The fact is that the real wage time series fits my recession narrative very well.*

Smith then pulls up a graph of real wages and uses it to argue that the data does not, in fact, fit Mulligan's narrative. It's definitely something you should check out, but right now there's something else I'd like you to take a look at. If you follow the link where Mulligan talks about blogging about the effect of labor supply on real wages, you get a column discussing the relationship between labor supply and productivity. This seems to be the relevant passage:

The second type of explanation is reduced labor supply.

Suppose, just for the moment, that people were less willing to work, with no change in the demand for their services. This means that employees would have to be more productive because they have to get by with fewer workers.

Of course, people have not suddenly become lazy, but the experiment gives similar results to the actual situation in which some employees face financial incentives that encourage them not to work and some employers face financial incentives not to create jobs.

Professor Douglas gave us a formula for determining how much output per work hour would increase as a result of a reduction in the aggregate supply of hours: For every percentage point that the labor supply declines, productivity would rise by 0.3 percentage points.

As mentioned earlier, in late 2008, labor hours were 4.7 percent below where trends from previous years would predict the number to be. According to Professor Douglas’s theory, this means productivity should rise 1.4 percent above its previous trend by the fourth quarter.

So let’s take a look at the numbers. Unlike in the severe recessions of the 1930s and early 1980s, productivity has been rising. Through the third quarter of 2008, productivity had risen six consecutive quarters, with an increase of 1.9 percent over the past three, or 0.7 percent above the trend for the previous 12 quarters.

Because productivity has been rising — almost as much as the Douglas formula predicts — the decreased employment is explained more by reductions in the supply of labor (the willingness of people to work) and less by the demand for labor (the number of workers that employers need to hire).

This way outside my field, so I could easily be missing the obvious here, but this post doesn't seem to support the claim that Mulligan was blogging on this question three years ago. That's not to say Mulligan's argument isn't valid or that it doesn't somehow imply his point about wages but if you're going to say "Three years ago I blogged about the effect of labor supply on real wages," you should probably mention wages in more than a passing way.

I can be sympathetic. Since I started blogging I've often recalled some prophetic observation I made in the past and started typing up a boastful post only to discover on review that I actually hadn't been that prophetic after all.

That's why I always reread old posts before I link to them; if I don't, someone else will.

Layoffs

Jeff Grubb has a very interesting window into how corporations act to try and create endless cycles of growth:

And part of it is that the corporation demands continued growth and profit. It can defer some of its growth for long-term development, or keep on an unsuccessful project that someone really likes, but really it boils down to guaranteed growth. And if you attain that growth, then they need to increase that rate of growth. And lord help you if you have a very good year - that very good year becomes the baseline for further calculations. In short, it is a vicious cycle.So they pass out the budgets for next year and now the departments have to plan. Yeah, some of that planning involves going back and telling the guys with the budgets that this makes no sense and sometimes that works. More often it involves figuring out what goes overboard in order to jack up profitability.Sometimes it is a new process that saves times or lowers cost of materials. Sometimes it is a new market that has been opened. Sometimes it is that "big hit" that suddenly arrives and surprises everyone (businesses actually don't like the "big hit" - it really screws up their planning. If they say you are going to lose 3 million this year and you instead MAKE 3 million, you make them look like idiots, and you will be punished accordingly).

There are two chilling comments here. One, is the idea that a good year can become the baseline for future expectations. So it makes sense to ensure that you don;t have any unexpected surprises. Two, which is the icing on the cake, is the idea that an unexpected burst of profitability will actually be punished. How this can actually be an efficient system is astonishing.

The standard explanation of "creative destruction" (badly run firms fade to be replaced with better run firms) presumes that we actually let large corporations fail. But there has been a general reluctance to do this in fields ranging from automobile manufacture to banking. Without that safety valve, this approach is going to be very dangerous to efficiency. In a later post, Jeff Grubb notes the CEO compensation for Hasbro (the subject of the first post) is pretty decent:

For those not linking, it is an announcement that the CEO of Hasbro is getting paid $23 Million this year. And yeah, it is like pouring oil on troubled water, then tossing in a match.Now, doing the digging in the article, the CEO gets a raise in salary from $1 Mill to $1.2 Mill (hardly chump change), and the rest being common stock. And to the best of my knowledge (the Internet will correct, of course), this means that it comes out of the company till - they are reassigning stock held by the company to the individual. And this assignment may have other strings attached - the stock cannot be sold except back to the company, it may only be sold at a particular price, it must be sold on leaving the company. So it is a fuzzy number, but a very large fuzzy number.The article also makes clear that this is a retention payment, negotiated last year, to keep the CEO around. It also notes that Hasbro had a weak 2010 in sales (stock prices went up, though). 2011 is nothing to write home about (stock prices have since deflated) and 2012 is not shaping up to be any better (Upcoming big movie: Battleship). So this is not about performance, but rather about stability. This is payment for showing up.

What is fascinating about part two is that this is the same company that just laid off two popular and productive long term employees in the Wizard's of the Coast division. So I googled game developer salaries and found this:

Game designers who work for a big company such as Hasbro or White Wolf Publishing can expect a more reliable salary, usually averaging between $30,000 and $50,000 per year.

Now let us presume fringe and overhead double the salary, and that both of the senior developers were at the very top of this range. The retention bonus portion of the CEO retention payment was enough to pay 400 developer-years of salary )both have fringe and overhead, it's unclear how this would work out in the details but this is a good starting estimate). Seriously, keeping the CEO around for another year was worth hundreds of experienced employees. What is ironic, is the base salary of the CEO is that of twenty senior developers (raised to that of twenty-four this year). That is actually a credible ratio of the benefit of a good CEO for a company (they have about as much influence as a couple of seasoned design teams). The additional $22 million is hard to understand. No wonder companies don't like comparisons between executive compensation and line worker compensation.

I do not really have a good idea about how to handle this issue in a more global sense, but I am deeply worried that this pattern could be playing out in corporations that we simply are unwilling to let go under.

That is a scary thought.
