    <title>Efficient Teaching</title>
<content type="html">
            &lt;p&gt;In &lt;a href='http://www.nytimes.com/2010/09/07/health/views/07mind.html'&gt;Forget What You Know About Good Study Habits&lt;/a&gt;, the Times describes some important findings about how students learn that could play an important role in your teaching:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Variety in content matters a great deal:&lt;/li&gt;
&lt;/ul&gt;

&lt;blockquote&gt;
    &lt;p&gt;In a study recently posted online by the journal Applied Cognitive Psychology, Doug Rohrer and Kelli Taylor of the University of South Florida taught a group of fourth graders four equations, each to calculate a different dimension of a prism. Half of the children learned by studying repeated examples of one equation, say, calculating the number of prism faces when given the number of sides at the base, then moving on to the next type of calculation, studying repeated examples of that. The other half studied mixed problem sets, which included examples all four types of calculations grouped together. Both groups solved sample problems along the way, as they studied.&lt;/p&gt;
    
    &lt;p&gt;A day later, the researchers gave all of the students a test on the material, presenting new problems of the same type. The children who had studied mixed sets did twice as well as the others, outscoring them 77 percent to 38 percent. The researchers have found the same in experiments involving adults and younger children.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;ul&gt;
&lt;li&gt;Variety in the study setting also has an impact:&lt;/li&gt;
&lt;/ul&gt;

&lt;blockquote&gt;
    &lt;p&gt;For instance, many study skills courses insist that students find a specific place, a study room or a quiet corner of the library, to take their work. The research finds just the opposite. In one classic 1978 experiment, psychologists found that college students who studied a list of 40 vocabulary words in two different rooms — one windowless and cluttered, the other modern, with a view on a courtyard — did far better on a test than students who studied the words twice, in the same room.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;ul&gt;
&lt;li&gt;Spacing of studying is important:&lt;/li&gt;
&lt;/ul&gt;

&lt;blockquote&gt;
    &lt;p&gt;An hour of study tonight, an hour on the weekend, another session a week from now: such so-called spacing improves later recall, without requiring students to put in more overall study effort or pay more attention, dozens of studies have found.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;This is really important stuff.  The experiments suggest potentially quite large payoffs in some cases for not much effort on the part of the instructor - primarily a reordering of how material is taught.  It's crazy that there is not an effective conduit for bringing this kind of material out of psychology journals and into the classroom (and no, a one-off in the NY Times doesn't count).&lt;/p&gt;

<content type="html">
            &lt;p&gt;&lt;a href='http://carlzimmer.com'&gt;Carl Zimmer&lt;/a&gt; just gave a short talk at &lt;a href='http://www.nature.com/natureconferences/scifoo/index.html'&gt;SciFoo&lt;/a&gt; on 3 rules for making sure your research is understood:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Mentalize - Try to get inside the head of your reader (someone without your knowledge) and see what you are saying through their eyes.&lt;/li&gt;
&lt;li&gt;Choose &lt;em&gt;every&lt;/em&gt; word - No jargon.  Carl's list of &lt;a href='http://bit.ly/IndexBanned'&gt;banned words&lt;/a&gt; is useful for avoiding jargon&lt;/li&gt;
&lt;li&gt;Take stories seriously - People think in stories - use them in communicating.  Make sure your talk hangs together&lt;/li&gt;

    <title>Learning to Communicate</title>
<content type="html">
            &lt;p&gt;A great &lt;a href='http://www.amacad.org/pdfs/scientistsUnderstand.pdf'&gt;article&lt;/a&gt; by Chris Mooney on the need for scientists to adopt better strategies for communicating with the public.  A central point:&lt;/p&gt;

&lt;blockquote&gt;
    &lt;p&gt;[Scientists] assume that if only their fellow Americans knew more about science and ceased to be in a state of knowledge deficit, a healthier relationship between science and the public would emerge.
    Yet there is another possibility: perhaps scientists misunderstand the public and fail to connect in part because of their own quirks, assumptions, and patterns of behavior. Indeed, there is no guarantee that increasing scientific literacy among the public would change core responses on contested scientific issues, for those responses are rarely conditioned by purely scientific considerations. Scientists and non-scientists often have very different perceptions of
    risk, different ways of bestowing their trust, and different means of judging the credibility of information sources. Moreover, members of the public strain their responses to scientific controversies through their ethics or value systems, as well as through their political or ideological outlooks—which regularly trump calm, dispassionate scientific reasoning.
    The powerful influence of politics and ideology is underscored by a rather shocking survey result: Republicans who are college graduates are considerably less likely to accept the scientific consensus on climate change than those who have received less education. These better-educated Republicans could hardly be said to suffer a knowledge deficit; a more apt explanation is that they are politically driven consumers of climate science information—and often quite voracious ones at that. They strain information through a powerful ideological sieve and end up loudly supporting a viewpoint that is incompatible with modern scientific understanding.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;The problems scientists are facing with communicating findings on such things as vaccines and global climate change, vaccines shows the real need for better training in communication skills.&lt;/p&gt;

    <title>Network, network, network</title>
<content type="html">
            &lt;p&gt;I got my job at Google due in large part to having a friend working there in a similar position.  My Microsoft job I found through a friend of a friend.  My postdoc advisor at Dartmouth had met me previously at a conference.  The same for my stint at Rice.  And so on.  Pretty much the only job I've ever gotten without having any kind of personal connection at the employer was my stint as a bicycle messenger in DC.&lt;/p&gt;

&lt;p&gt;One reads such tales about the importance of networking all the time.  What's unsatisfying is that they're all anecdotal.&lt;/p&gt;

&lt;p&gt;I've been reading &lt;a href='http://www.amazon.com/Malcolm-Gladwell/e/B000APOE98'&gt;Malcolm Gladwell's books&lt;/a&gt; recently (they're great!) and came across this in &lt;a href='http://www.amazon.com/Tipping-Point-Little-Things-Difference/dp/0316346624'&gt;&lt;em&gt;The Tipping Point&lt;/em&gt;&lt;/a&gt;:&lt;/p&gt;

&lt;blockquote&gt;
    &lt;p&gt;In his classic 1974 study Getting a Job, Granovetter looked at several hundred professional and technical workers from the Boston suburb of Newton, interviewing them in some detail on their employment history.  He found that 56 percent of those he talked to found their job through a personal connection.  Another 18.8 percent used formal means - advertisements, headhunters - and roughly 20 percent applied directly.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;Note that the people in question are professional and technical workers - probably not so different than PhDs looking for industry jobs.  So this kind of thing is quite common.&lt;/p&gt;

&lt;blockquote&gt;
    &lt;p&gt;But, curiously, Granovetter found that of those personal connections, the majority were &quot;weak ties.&quot;  Of those who used a contact to find a job, only 16.7 percent saw that contact &quot;often&quot; - as they would if the contact were a good friend - and 55.6 percent saw their contact only &quot;occasionally.&quot;  Twenty-eight percent saw the contact &quot;rarely.&quot;  People weren't getting their jobs through friends.  They were getting them through their acquaintances.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;Gladwell goes on to discuss the idea of &quot;weak ties&quot; in some detail, and it's pretty interesting.  The point for PhDs is that job networking isn't about having tons of friends - it's more about having lots of acquaintances.  That means getting out to conferences and making sure that you meet lots of people.  But there are some less obvious ways to make a lot of acquaintances, too:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Participate in open source software projects.  It's a great way to showcase your work, you learn a lot of valuable skills, and you can meet people who are outside the academic bubble.  That was how I met my Google connection.&lt;/li&gt;
&lt;li&gt;Participate in relevant non-research-related activities - organize a speaker series, participate in your graduate student or postdoc association, take a leadership role with your professional society, blog.  My Microsoft connection I knew through science policy activities.&lt;/li&gt;
&lt;li&gt;Find hobbies that bring you in touch with lots of people.  I've had a few interesting job leads through one of my running clubs.&lt;/li&gt;
&lt;/ul&gt;

    <title>What makes a good scientist?</title>
<content type="html">
            &lt;p&gt;There's an &lt;a href='http://www.nytimes.com/2010/01/15/health/14chen.html'&gt;interesting piece in today's NY Times&lt;/a&gt; about what factors predict whether people will be good doctors.  Everyone currently focuses on things like the MCAT, which measures some combination of basic domain knowledge and cognitive skills.  What the &lt;a href='http://www.ncbi.nlm.nih.gov/pubmed/19916659'&gt;Journal of Applied Psychology study&lt;/a&gt; described in the Times found is that personality matters a great deal.&lt;/p&gt;

&lt;blockquote&gt;
    &lt;p&gt;At the start of the study, the researchers administered a standardized personality test and assessed each student for five different dimensions of personality — extraversion, neuroticism, openness, agreeableness and conscientiousness. They then followed the students through their schooling, taking note of the students’ grades, performance and attrition rates.&lt;/p&gt;
    
    &lt;p&gt;The investigators found that the results of the personality test had a striking correlation with the students’ performance. Neuroticism, or an individual’s likelihood of becoming emotionally upset, was a constant predictor of a student’s poor academic performance and even attrition. Being conscientious, on the other hand, was a particularly important predictor of success throughout medical school. And the importance of openness and agreeableness increased over time, though neither did as significantly as extraversion. Extraverts invariably struggled early on but ended up excelling as their training entailed less time in the classroom and more time with patients.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;Google tried a similar exercise a few years back with software engineers and had enough success that the results have been incorporated into hiring process: &lt;a href='http://www.nytimes.com/2007/01/03/technology/03google.html'&gt;Google Answer to Filling Jobs Is an Algorithm&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;I think it would be both fascinating and useful to examine the question of what factors predict success in science and engineering more broadly.  The current approach seems all to focused on measures of convenience like GRE scores and fuzzy things like intuition.  There are a lot of assumptions about who will be good that I think warrant empirical testing.&lt;/p&gt;

    <title>Pure vs Applied Research</title>
<content type="html">
            &lt;p&gt;Stephen Quake, a Stanford biophysics professor, has been guest writing a column in the &lt;em&gt;New York Times&lt;/em&gt;.  His opening column was on the &lt;a href='http://judson.blogs.nytimes.com/2009/02/17/the-absurdly-artificial-divide-between-pure-and-applied-research/'&gt;links between pure and applied research&lt;/a&gt;.  He raises a lot of great points about how applied research can lead to new ideas for pure research and vice versa (and includes a few nice digs at theory snobs who pooh-pooh those of us who toil in the applied trenches).&lt;/p&gt;

&lt;p&gt;Given daunting problems of energy and climate change, I think we are going to see increasing funding emphasis on more applied work - this is for the good, I think, but will surely raise hackles among some.  Quake's point about the two-way flow of ideas is an important one to remember as is his model of hybrid work in both pure and applied research.&lt;/p&gt;

    <title>Graduate Education at Stanford</title>
<content type="html">
            &lt;p&gt;&lt;a href='http://www-vlsi.stanford.edu/~horowitz/'&gt;Mark Horowitz&lt;/a&gt;, Associate Vice Provost for Graduate Education at Stanford, gave a talk at Google a few weeks ago about some of the things Stanford is working on to enhance the quality of its graduate programs.  After many years (a decade or more?) of having no senior leadership with responsibility for graduate education at the university level, Stanford has finally created an office of graduate education.  Mark's talk was an overview of the initiatives coming out of the new office.&lt;/p&gt;

&lt;p&gt;Stanford's new activity in graduate education is based on an internal &lt;a href='http://www.stanford.edu/dept/president/CGE2005.pdf'&gt;report&lt;/a&gt;.  The basic thrusts are &lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;more interdisciplinary education,&lt;/li&gt;
&lt;li&gt;greater diversity, and&lt;/li&gt;
&lt;li&gt;leadership training.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;These are all fairly standard ideas, but a few things struck me about Stanford's approach.&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;Stanford has a ridiculous amount of financial resources.  It appears that the university is backing this initiative wholeheartedly.  This is not just a few seminars cobbled together by an underfunded graduate or postdoc office - it looks like the real deal.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Stanford has amazing courses throughout the institution, but usually access to courses in one department is limited to students in that department.  The new Office is doing the smart thing of trying to better leverage existing resources.  To give a sense of how serious the university is about this, they are talking about things like moving the Law School from a semester to a quarter system (maybe the other way around?  this is from memory) so that students outside the Law School can more easily take graduate courses and vice versa.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;One problem people have with taking classes outside their department is that it's hard to find appropriate classes in other fields because there are so many classes out there.  The catalog is paper based (!) and there is not much descriptive material on courses.  Stanford has set up a web site called &lt;a href='http://courserank.stanford.edu/CourseRank/'&gt;CourseRank&lt;/a&gt;, which is an exercise in using collaborative filtering to help students find relevant courses outside their departments.  I suspect that CourseRank may be an exercise in trying to set up a social networking site for the sake of cool points, but the idea seems sound.  One lower tech and much cheaper way to accomplish some of the same goals would be to do some basic mining of data from the registrar.  Looking at past cross-disciplinary enrollments would be a simple way to provide students with suggestions for possible good courses to take outside their departments.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Stanford is setting up career development as formal classes during the summer and before fall quarter (the &lt;a href='http://sgsi.stanford.edu/course_overview/course_overview_2008.html'&gt;Stanford Graduate Summer Institute&lt;/a&gt; ).  Students have to apply, and in some cases pay a fee.  Having an application process is smart - it makes the course into a desirable thing that you have to compete for rather than a freebie extra thing that people have to be dragged to.  The fee accomplishes the same purpose, plus provides resources to sustain the effort.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Career development workshops are being pitched as &quot;leadership training&quot;.  It's the same thing, but &quot;leadership&quot; is much sexier and probably easier to sell.  I suspect that because of the word's additional usage as &quot;leader in a field&quot;, &quot;leadership&quot; has positive connotations even for the most unreconstructed students-must-always-be-at-the-bench faculty.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Stanford is trying to set up mentors for students outside of the regular faculty advisors.  The vision appears to be pairing students with area professionals, e.g. people at dot-coms, biotechs, etc.  Definitely a good way to provide some guidance that many faculty are ill-equipped to do.&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;All in all a good effort.  It's especially promising because places like Stanford tend to inspire places that want to be like Stanford.  I'm looking forward to seeing the results and to seeing other universities try to follow in their footsteps.&lt;/p&gt;

    <title>Better Adaptation</title>
<content type="html">
            &lt;p&gt;If the people with skills that are the most valuable outside of academia leave universities in disproportionate numbers (&lt;a href='http://blog.phds.org/2007/8/9/survival-of-the-fittest'&gt;as I think they do&lt;/a&gt;), students will miss out on what they have to offer, and there the risk that academia will grow progressively more insular.  How might one counteract this effect?&lt;/p&gt;

&lt;p&gt;One straightforward remedy is to create more opportunities for interactions between academia and industry.  There is already some work in this area in the form of industrial postdocs.  I think these kinds of positions can be effective mechanisms for helping people transition to industry positions, but when used as such, their impact is limited.  Unless the postdoc returns to academia (and I would guess that a relatively small fraction do), only one trainee really benefits.&lt;/p&gt;

&lt;p&gt;It's moving people in the opposite direction, from industry to academia where they can teach, that could really make a difference.  This kind of thing happens informally on occasion - a famous retired luminary from industry will get some office space in a department and show up from time to time - but to really maximize the benefits, one would need to recruit people still active in industrial research and figure out ways to have them impart their skills and knowledge (particularly in areas less prevalent in academia) to a broad range of students and faculty members.&lt;/p&gt;

&lt;p&gt;I think such a program could be run on a small scale relatively inexpensively: a set of teaching fellowships that could serve the role of a sabbatical for people in industry.  In addition to being able to offer some unique courses, departments would benefit by gaining relationships with corporate labs - collaborations could mean new funding sources as well as jobs for promising students.  Companies would benefit from potential technology transfer and having their people learn new skills, so everybody wins.&lt;/p&gt;

    <title>The Importance of Communication Skills in Science</title>
<content type="html">
            &lt;p&gt;The &lt;a href='http://en.wikipedia.org/wiki/Poincar%C3%A9_conjecture'&gt;Poincare conjecture&lt;/a&gt; was until recently one of the great unsolved problems in mathematics.  Stephen Smale proved the conjecture for 5 or more dimensions in 1961, Michael Freedman proved the conjecture for 4 dimensions in 1982, and Grigori Perelman proved the final case for 3 dimensions in 2003.  All 3 mathematicians won Fields Medals for their work (though Perelman declined the award).&lt;/p&gt;

&lt;p&gt;Smale's and Freedman's proofs were widely lauded, and both have since landed prestigious appointments: Smale was a professor at Columbia and then Berkeley; Freedman was a professor at UCSD and is now at Microsoft Research.  Perelman's proof, in contrast, has generated considerable controversy; he is currently unemployed and lives with his mother in St. Petersburg, Russia.&lt;/p&gt;

&lt;p&gt;A &lt;a href='http://www.newyorker.com/archive/2006/08/28/060828fa_fact2'&gt;fascinating account of Perelman's saga&lt;/a&gt; recently appeared in &lt;em&gt;The New Yorker&lt;/em&gt;.  The gist of the story is that rather than publishing a formal proof of the Conjecture, Perelman posted a series of sketches to arXiv.  Other authors subsequently refined the sketches into a full proof.  Because these authors did not understand some parts of Perelman's sketch, they inserted some of their own methods in places, and as a result have claimed credit for the final proof.  Perelman has renounced mathematics altogether over the dispute.&lt;/p&gt;

&lt;p&gt;Authorship is particularly relevant in this case, as the Clay Mathematics Institute has offered a &lt;a href='http://www.claymath.org/millennium/'&gt;million-dollar prize&lt;/a&gt; for a proof.  Because Perelman did not publish anything in a peer-reviewed journal, it is not clear that he is eligible.&lt;/p&gt;

&lt;p&gt;I think that many researchers believe that if the science is good, everything else will follow.  Perelman's case is a cautionary tale: he has clearly done brilliant work, but his mode of presenting his results has cost him dearly.&lt;/p&gt;

    <title>Effective Teaching</title>
<content type="html">
            &lt;p&gt;There's an &lt;a href='http://chronicle.com/weekly/v53/i40/40a01401.htm'&gt;interesting piece&lt;/a&gt; in today's Chronicle of Higher Ed on the effectiveness of regular quizzes on learning.  Basically, it appears that the act of recalling information (as for a quiz) reinforces the memory of that information.  Quizzing people soon after they learn something produces pretty big improvements in their long term retention of that information.&lt;/p&gt;

&lt;p&gt;That's useful to know, and it agrees with my own positive experiences using regular, short quizzes in the classroom.  Quizzes have the additional benefit of forcing people to keep up with the material rather than trying to cram it all in at the end.  Since class materials are typically cumulative, mastering material as one goes along means that one is able to better understand new material in the context of recently learned material.&lt;/p&gt;

&lt;p&gt;Other simple things can make a big difference, too.  I taught honors multivariate calculus most fall terms when I was at Dartmouth.  There were 3 sections of the class, each taught by a different person.  We all shared a syllabus, midterms, and finals, but apart from that were free to teach the course however we wanted.  One thing I did that I thought was particularly effective was to spend about 2/3 of the class lecturing and then for the remainder of the class, pair up the students and have them work on an in-class exercise that made use of the concepts from the lecture.  My sense was that it worked really well because the slower students ended up getting individualized attention from the faster students, and the faster students solidified their understandings by having to explain what they had just learned.  In the end, my students invariably scored higher than those from the other two sections on the midterms and the finals, a fact that I attribute to the pairing exercises.  Not by a few points, either - the difference in the class averages was often on the order of a letter grade.  I'm sure this kind of thing is well-studied, but I was just making it up as I went along.  &lt;/p&gt;

&lt;p&gt;Here's the thing I'm wondering: there is a &lt;em&gt;ton&lt;/em&gt; of research in education.  Why do so few of the findings make it to the classroom?  I don't know of any institutionalized mechanisms for extracting the most salient findings from the education literature and disseminating them to people who teach at the university level (sure, there are little seminars and special classes here and there; I'm talking something that goes to &lt;em&gt;everybody&lt;/em&gt;).  Why is that?  Is there no reward structure in place for education researchers to disseminate their findings beyond education journals (where they will be read by a handful of other education researchers)?  I suspect one could make tremendous improvements in S&amp;amp;E education simply by better publicizing &lt;em&gt;things that are already known.&lt;/em&gt;&lt;/p&gt;

&lt;p&gt;In fact, the whole enterprise could probably be done for maybe a few hundred thousand dollars given an enterprising faculty member with a bright master's student or two.  Here's a great master's thesis idea: &lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Put together a review paper on what's known about the most effective ways of teaching college-level science / math / engineering.&lt;/li&gt;
&lt;li&gt;Extract from that paper a 10-page executive summary.  &lt;/li&gt;
&lt;li&gt;Talk nicely to a foundation to get funds to print and widely disseminate copies to grad students, postdocs, and junior faculty.&lt;/li&gt;
&lt;li&gt;Bask in fame.&lt;/li&gt;
&lt;/ol&gt;

    <title>Bubble Benefits</title>
<content type="html">
            &lt;p&gt;Slate's Daniel Gross has a new book out, &lt;a href='http://www.slate.com/id/2165929/nav/tap1/'&gt;Pop!  Why Bubbles are Great for the Economy&lt;/a&gt;.  It's an interesting argument: while bubbles are wasteful, oftentimes (1) there are a few enduring successes, and (2) even the failures can leave behind valuable infrastructure that then gets consolidated and reused by sounder post-bubble businesses.&lt;/p&gt;

&lt;p&gt;EBay, Amazon, and Google all survived the recent dot-com boom.  Moreover, there was a huge buildout of telecommunications capacity that is finally starting to be used effectively.  Less obviously, bubble times can also result in &quot;mental infrastructure.&quot;  One form this takes is fundamental changes in consumer behavior.  Huge amounts of advertising dollars were spent in the 90's convincing people to shop and invest online.  Now that people accept that these are reasonable things to do, new businesses benefit.&lt;/p&gt;

&lt;p&gt;A second form of mental infrastructure is training for service providers.  The dot-com era generated new programming practices (e.g. agile methodologies, design patterns), a wealth of documentation, new publishers (O'Reilly, Pragmatic Studios), schools, and huge numbers of trained software engineers, designers, testers, project managers, and on and on.&lt;/p&gt;

&lt;p&gt;It's this latter piece that's of potential interest for scientists and engineers.  Academia is incredibly slow to react to changes in the market for a whole host of structural reasons, and as a result, there are substantial excesses of PhDs cranked out in many fields.  Bubbles can offer an out for these newly minted graduates by providing &lt;em&gt;for some&lt;/em&gt; a relatively easy direction in which to make a lateral career move.&lt;/p&gt;

&lt;p&gt;Right now there are at least 2 areas in which there is bubble-like activity: Web 2.0 companies and quantitative finance.  I'm currently in Portland at &lt;a href='http://conferences.oreillynet.com/rails/'&gt;RailsConf&lt;/a&gt;, and it's a bit of a Web 2.0 developer frenzy.  Dozens of new little companies are hiring, and there is buzz about all sorts of interesting projects going on.  If you're smart, &lt;a href='http://rubyonrails.org'&gt;Ruby on Rails&lt;/a&gt; is easy to pick up, and it's a pretty good plan B.  As for quantitative finance, over on &lt;a href='http://jobs.phds.org'&gt;jobs.phds.org&lt;/a&gt; there are a couple dozen new ads for &lt;a href='http://jobs.phds.org/jobs/job_listings/finance'&gt;quantitative analysts&lt;/a&gt; every week.  A fair number of the ads are for mathematicians / physicists with no prior finance experience, and the pay well into 6 figures, even for the entry level positions.&lt;/p&gt;

&lt;p&gt;Now neither of these areas is going to give you tenure-level job stability.  The bottom is going to fall out sooner or later in both; probably sooner with the hedge funds.  However, in both cases the pay is substantially greater than what you'd get as a postdoc (by a factor of 3 to 5), and you'll acquire skills that you can use in whatever you do next.  Which makes more sense economically?  3-5 years as a postdoc earning $35K and preparing for an incredibly scarce tenure track job?  Or the same amount of time earning far more as a developer or a quant?  There's considerable uncertainty about next steps in either case, but at least in one you're getting paid.&lt;/p&gt;

&lt;p&gt;I think the real challenge for PhDs is more of an attitude adjustment, namely accepting that:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;your education is a &lt;a href='http://en.wikipedia.org/wiki/Sunk_cost'&gt;sunk cost&lt;/a&gt;,&lt;/li&gt;
&lt;li&gt;research is not necessarily the One True Path,&lt;/li&gt;
&lt;li&gt;you are still a fine person even if you don't write papers for a living, and&lt;/li&gt;
&lt;li&gt;you always have to learn and adapt your skills.&lt;/li&gt;
&lt;/ul&gt;

    <title>The Scientific Communications Act of 2007</title>
<content type="html">
            &lt;p&gt;There's an interesting new bill working its way through the House: &lt;a href='http://thomas.loc.gov/cgi-bin/query/z?c110:H.R.1453.IH:'&gt;The Scientific Communications Act of 2007&lt;/a&gt;.  (A tip of the hat to the fine folks over at &lt;a href='http://arstechnica.com/news.ars/post/20070401-new-bill-would-improve-science-outreach.html'&gt;ArsTechnica&lt;/a&gt; for cluing me in to its existence).&lt;/p&gt;

&lt;p&gt;The bill allocates $50 million over 5 years to the NSF to improve the communication skills of S&amp;amp;E graduate students.  The rationale offered in the bill is pretty straightforward:&lt;/p&gt;

&lt;p&gt;Grad students often don't get training in communication skills, and these skills would help scientists talk to:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;the public (i.e. increase public support for science)&lt;/li&gt;
&lt;li&gt;policy makers (i.e. help scientific findings be incorporated into public policy), and&lt;/li&gt;
&lt;li&gt;business leaders (i.e. help businesses use science to create new / better products)&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;All very sensible stuff, it seems to me.  I am left wondering a few things:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;First and foremost, how did this bill come to be?  The lousy quality of graduate training in communication skills doesn't seem to be the kind of thing that most members of Congress spend their time worrying about.  I wonder if this is the work of a AAAS fellow?  Is there a good conduit for similar ideas to make their way up to the Hill?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Is this level of micromanagement unusual?  Or does Congress go in and make NSF do little projects like this all the time?  If the former, then I have rather mixed feelings about the bill.  Despite the fact that I think communication skills should be taught, I'd be concerned that a different Congress might impose other, less desirable missions on the NSF, say, a set of grants to shore up the foundations for Creation Science.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Is this likely to go anywhere?  Or is this just some kind of gesture?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Finally, why doesn't the NSF do this already?  This seems like a no-brainer, and it's entirely in the self-interest both of the NSF as an institution and of scientists, since better public support of science presumably means more funding.&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;I have a couple of contacts on the Hill (not very good ones, unfortunately) will see if I can track down some answers.  If you have any pointers to good sources, please contact me!&lt;/p&gt;

    <title>Stress of Science, Science of Stress</title>
<content type="html">
            &lt;p&gt;I am scheduled to give a seminar in 2 weeks on a topic that I have less familiarity with than I'd like.  The people from whom I am supposed to get a crucial data set for the talk aren't returning my calls.  My backup plan has been scooped by a seminar in the same series on Monday.  So I'm a little panicked.  Not &lt;em&gt;too&lt;/em&gt; panicked, mind you - I have learned from long experience that I will eventually figure something out, and fear has proven quite an effective stimulus for creative thinking in the past for me.  But it's enough to cause all the physiological effects of stress to kick in.&lt;/p&gt;

&lt;p&gt;Back when I was an undergraduate, I had some vague notion that work as a researcher would be motivated primarily by a quest for a state of &lt;a href='http://en.wikipedia.org/wiki/Mihaly_Csikszentmihalyi'&gt;flow&lt;/a&gt;.  That's definitely there, but it is frequently punctuated by moments of terror.  Research careers can be quite stressful, even in the best of times.  Experiments can go awry, conference deadlines can sneak up, and there is always last minute lecture preparation.&lt;/p&gt;

&lt;p&gt;I recently finished an excellent book by Robert Sapolsky on the physiology of stress, &lt;a href='http://www.amazon.com/gp/product/0716732106?ie=UTF8&amp;amp;tag=phdsorgsciencmat&amp;amp;linkCode=as2&amp;amp;camp=1789&amp;amp;creative=9325&amp;amp;creativeASIN=0716732106'&gt;&lt;em&gt;Why Zebras Don't Get Ulcers&lt;/em&gt;&lt;/a&gt;.  I highly recommend it.&lt;/p&gt;

&lt;p&gt;&lt;img src='http://images.amazon.com/images/P/0716732106.01._AA_SCMZZZZZZZ_.jpg' alt='Why Don\'t Zebras Get Ulcers?' /&gt;
&lt;a href='http://www.amazon.com/gp/product/0716732106?ie=UTF8&amp;amp;tag=phdsorgsciencmat&amp;amp;linkCode=as2&amp;amp;camp=1789&amp;amp;creative=9325&amp;amp;creativeASIN=0716732106'&gt;&lt;em&gt;Why Don't Zebras Get Ulcers?&lt;/em&gt;&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;First, it's a great piece of science writing.  Sapolsky manages to keep things lively and engaging without dumbing things down.  Part of what keeps things moving along is his use of an informal tone, something that unfortunately is drummed out of a lot of people by writing endless journal articles.  The book is a lot closer to sitting in an undergraduate seminar with a friendly but brilliant prof than reading a bunch of journal articles.  He's also generous with credits - I discovered that a friend of mine did an undergraduate internship with Sapolsky because he spent a half page describing the work she had done.  He mixes established knowledge with informed speculation, being careful to distinguish between the two.&lt;/p&gt;

&lt;p&gt;Second, the subject matter hits pretty close to home.  Having spent the past 20 years or so in fairly high-stress environments, I've tended to brush aside suggestions that I try to adjust (sorry, Mom!).  Vague notions that stress is &quot;bad&quot; somehow just don't do it for me.  Sapolksy, in contrast, spells out in grim detail exactly what chronic stress does, and believe me, I'm listening now.&lt;/p&gt;

&lt;p&gt;Two effects of stress are particularly relevant to researchers:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;Chronic stress wreaks havoc with the hippocampus, which plays a key role in memory and learning.  So frantic cramming can, in the long term, reduce your ability to retain information.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Chronic stress is linked to depression, which in turn can reduce your ability to produce by sapping your motivation.&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;There's an interesting policy implication: it suggests that universities might do well to invest in stress-reduction / mental health services for researchers.  Given that a sense that one is not in control of one's work is a major risk factor for depression (google &lt;a href='http://www.google.com/search?q=learned+helplessness&amp;amp;ie=utf-8&amp;amp;oe=utf-8&amp;amp;rls=org.mozilla:en-US:official'&gt;&quot;learned helplessness&quot;&lt;/a&gt;) and other stress-related morbidity, graduate students and postdocs could be some of the biggest beneficiaries.&lt;/p&gt;

&lt;p&gt;A &lt;a href='http://www.ocf.berkeley.edu/~gmhealth/reports/gradmentalhealth_report2004.html'&gt;recent survey at Berkeley&lt;/a&gt; suggests stress-related mental health issues are startlingly common among graduate students:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;&quot;In the last 12 months, 45.3% of respondents had experienced an emotional or stress-related problem that significantly affected their well being and/or academic performance.&quot;&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&quot;9.9 % of respondents seriously considered suicide in the past 12 months.&quot;&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Fortunately, remedies are fairly straightforward and inexpensive.  Exercise, for example, has big benefits, so simple things like intramural sports for grad students and gym access for postdocs can help a lot.  I learned at a recent conference that Vanderbilt has hired a full-time counselor for its postdocs, and apparently it's been a very successful experiment.&lt;/p&gt;

&lt;p&gt;Another interesting thing I discovered in Sapolsky's book: there is interesting evidence that men and women's responses to stress are fairly different.  The well-known &lt;a href='http://en.wikipedia.org/wiki/Fight_or_flight'&gt;&quot;fight or flight&quot;&lt;/a&gt; response is apparently a better description of the male response to stress than the female.  The female response is characterized as &lt;a href='http://www.apa.org/monitor/julaug00/stress.html'&gt;&quot;tend and befriend&quot;&lt;/a&gt;:&lt;/p&gt;

&lt;blockquote&gt;
    &lt;p&gt;In particular, they propose that females respond to stressful situations by protecting themselves and their young through nurturing behaviors--the &quot;tend&quot; part of the model--and forming alliances with a larger social group, particularly among women--the &quot;befriend&quot; part of the model. Males, in contrast, show less of a tendency toward tending and befriending, sticking more to the fight-or-flight response, they suggest.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;This work dovetails nicely with some research by &lt;a href='http://www.haverford.edu/econ/Faculty/Preston/Preston.html'&gt;Anne Preston&lt;/a&gt; on &lt;a href='http://www.agu.org/sci_soc/education/jsc/preston.ppt'&gt;why people leave science&lt;/a&gt;.  Preston found that female graduate students who did not have a mentor were much more likely to drop out of graduate school than those with a mentor.  Intriguingly, there was no such effect for males.  Tend-and-befriend provides a potential explanation: a mentor may play a more important role in women's mechanisms for coping with the stress of graduate study than in those of men.&lt;/p&gt;

&lt;p&gt;This is potentially good news, if true: the &lt;a href='http://postdoc.sigmaxi.org/results'&gt;Sigma Xi Postdoc Survey&lt;/a&gt; found that women who worked for female PIs were substantially more likely to consider their PI to be a mentor than women working with male PIs.  As the ranks of women increase in the professoriate, we may well see a virtuous cycle: as female students and postdocs have greater opportunities to find a female mentor, retention rates may increase, which in turn could lead to further increases in women in the faculty.&lt;/p&gt;

    <title>Getting Research Ideas</title>
<content type="html">
            &lt;p&gt;How does one come up with good research ideas?  Grad school teaches you a lot about how to pursue them once you have them.  You also learn a lot of techniques for evaluating your ideas so you can sift through and find good ones.  But are there things you can do to help ensure that your pool of ideas actually includes some good ones?&lt;/p&gt;

&lt;p&gt;Seth Roberts, a psychology professor at UC Berkeley, has a fascinating &lt;a href='http://repositories.cdlib.org/postprints/117/'&gt;essay about how he comes up with good ideas&lt;/a&gt;.  His system is not for everyone - he obsessively records dozens of measurements of himself and periodically sifts through the data.  Because he studies appetite and weight control, he has a lot of opportunities for self-experimentation, and he seems to take them all up: an all-sushi diet, drinking gallons and gallons of water per day, shots of olive oil, and more.&lt;/p&gt;

&lt;p&gt;This past weekend I attended the &lt;a href='http://wiki.blogtogether.org/blogtogether/'&gt;NC Science Blogging Conference&lt;/a&gt; where &lt;a href='http://www.blogger.com/profile/6833158'&gt;Jean-Claude Bradley&lt;/a&gt; from Drexel suggested another &lt;a href='http://drexel-coas-talks-mp3-podcast.blogspot.com/2007/01/nc-science-blogging-conference.html'&gt;interesting approach&lt;/a&gt;.  He searches Google Scholar for phrases like, &quot;what is needed now&quot;, &quot;what is missing is&quot;, &quot;there is a pressing need&quot;, &quot;what is now needed&quot;, &quot;needs to be synthesized&quot;, &quot;pressing problem&quot;, etc.  For example, &lt;a href='http://scholar.google.com/scholar?q=%22a+pressing+need%22+2005+chemistry&amp;amp;hl=en&amp;amp;lr=&amp;amp;btnG=Search'&gt;&quot;there is a pressing need&quot; 2005 chemistry&lt;/a&gt; turns up phrases for things that people have identified in (mostly) chemistry papers in 2005 as being important.&lt;/p&gt;

    <title>Postdoc Leadership Mentoring Project</title>
<content type="html">
            &lt;p&gt;On the subject of &lt;a href='http://blog.phds.org/2006/12/6/leadership-in-science'&gt;cultivating leadership in scientists&lt;/a&gt;, the following showed up in my mailbox recently:&lt;/p&gt;

&lt;blockquote&gt;
    &lt;p&gt;The NPA is pleased to announce the Postdoc Leadership Mentoring Project, sponsored by the NPA and the Alfred P. Sloan Foundation. This innovative program seeks to connect experienced leaders in the postdoctoral community with individuals and institutions interested in establishing postdoc offices and/or associations at their home institutions. Experienced leaders will serve as mentors to those forming new organizations or working to revive past organizations.&lt;/p&gt;
    
    &lt;p&gt;... &lt;/p&gt;
    
    &lt;p&gt;At the Annual Meeting [March 30-April 1], recipients of the awards will participate in a special session on establishing postdoc offices and/or associations and will connect with their mentors or mentees face-to-face. Following the meeting, mentors and mentees will continue to strengthen their relationship through participation in monthly teleconferences. Finally, some award recipients may be eligible for site visits to their research institutions by a team of experts to further the growth of their new postdoc organizations.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;I think this kind of thing can potentially have a big impact on the quality of the training scientists receive.&lt;/p&gt;

&lt;p&gt;Notice who initiated it: postdocs, not senior scientists.  That's good and bad: good in that postdocs are taking the initiative (showing leadership in the process), but bad in that they have &lt;em&gt;had&lt;/em&gt; to do so.&lt;/p&gt;

&lt;p&gt;Kudos to the National Postdoc Association.&lt;/p&gt;

&lt;p&gt;You can &lt;a href='http://www.nationalpostdoc.org/site/c.eoJMIWOBIrH/b.2291841/k.6DCC/PDAPDO_Travel_Awards.htm'&gt;find out more here&lt;/a&gt;&lt;/p&gt;
