I recently had to make a presentation at work on ontologies--the basics, really, of what they are, how they're used, and what the heck is OWL? I found the following links and sites helpful in creating my presentation, and thought I'd share them here.

From Ralph Waldo Emerson’s journal, dated October 1848:

Every poem must be made up of lines that are poems.

Incidentally, it’s always seemed a bit curious to me that given what the Americans say they owe to the Separatists and the Pilgrim Fathers, and indeed it could be proved that they owe a great deal, the English are so often the villains and while we have people in America happy to be Afro-Americans and Irish Americans and Hispanic Americans, I have yet to meet anyone in the United States who has told me that he was an Anglo-American.

Because, for whatever reason, I'm nervous about entering a world that plays according to different rules than the corporate one I'm used to, I've taken to reading and bookmarking a lot of "how to succeed in academia" articles. So as I come across good advice (or at least good advice for me), I'll post it here.

In 2005, Matthew Pearson wrote a letter for the new graduate economics students at UC Davis. The letter (PDF) has some advice specific to that program, but there's other good general advice buried in there too.

• In the first year, it's "about learning that survival is not all about intelligence, nor passion, but commitment." Learning the fundamentals can be grueling, you'll feel like an imposter, but keep going. Pearson says: "Some research in behavioral economics suggests that people are happier with decisions they know are irreversible. Simply putting that decision [to quit] out of the realm of possibility will relieve you of a lot of burden."
• Although he talks about preliminary exams at one point, the advice can be generalized: "...[I]t is very important to believe that you have it in you to pass." Learn from your mistakes, take your grades as indicators of where you may need to adjust and improve. "Freaking out is a waste of your time and energy."
• "Begin to develop your strategy to pass early on." He's talking about the prelims here, but I'm thinking in terms of my master's paper I'll have to write. Ideally, my projects over the next few years will feed into the paper, so that the effort to compile, research, and write will be minimal. (My adviser suggested looking for a subject at my workplace; maximize what I already know well.)
• I really like this bit of advice. He's talking about getting the fundamentals of economics in your bones, but again, I'm expanding its purview:

Develop your intuition. I cannot stress this enough. As I mentioned above about studying for understanding and not merely memorizing, you must believe that the intuition is there and that the material will seem much, much easier once you have grasped it...When you aim for this kind of understanding, however, things become so much clearer.

Often the barrier to true understanding is the nagging sense that you have SO MUCH to study, so you really must move on to the next topic. However, grazing over lots of material gathering cursory familiarity can be, at best, far less productive than studying one thing until you really understand it and do not need to depend on memorized content...[Me: Hmmmm.] Repetition [can be] sufficient for understanding less challenging material, but this is no longer the case.

[Me: In my spring information course, I felt bombarded by so many new concepts--RDF, metadata, ontologies, thesauri--that it wasn't until I was studying for the final that I grokked how they all fit together. Until that time, they were only vocabulary words. Given the pace of the course, and the fact that I was working full-time and taking a second course, there really was no time to do more than keep my head above water. Also, where I'm at now, everything is basic and fundamental. Intuition will only develop for me after I've worked with these things some more.]

• "Develop your student capital." Learn to ask your classmates, professors, and TAs questions, no matter how silly you might feel. "There is no place for pride when you do not understand."
• Develop an effective method for dealing with note-taking and note-studying. "Choose something that addresses your weaknesses effectively." (Spoken like a true lifehacker.) Pearson takes notes on looseleaf paper, transfers them to a binder, and then makes his own notes on the other side of the page as he goes through them. A nice system. I'm still working out mine. What I did in the spring worked OK, but didn't encourage revisiting the material and refreshing itself in my mind.
• Rest effectively--this means time with friends and family, exercising, getting enough sleep. And yes, that means there can be "unproductive rest," as he calls it, like zoning out in front of the teevee.

Overheard at the bagel store, when the sassy counter gal was teasing her male co-worker

“I don’t need an A-plus. I’m happy with an A.”

Melvyn Bragg’s In Our Time newsletter reproduced this fascinating document from WWI war hero and poet Siegfried Sassoon, denouncing the conduct of the war at great personal risk. It was originally printed in The Times in 1917.

I am making this statement as an act of wilful defiance of military authority, because I believe that the war is being deliberately prolonged by those who have the power to end it. I am a soldier, convinced that I am acting on behalf of soldiers. I believe that this war, upon which I entered as a war of defence and liberation, has now become a war of aggression and conquest. I believe that the purposes for which I and my fellow-soldiers entered upon this war should have been so clearly stated as to have made it impossible to change them, and that, had this been done, the objects which actuated us would now be attainable by negotiation. I have seen and endured the sufferings of the troops, and I can no longer be a party to prolong these sufferings for ends which I believe to be evil and unjust. I am not protesting against the conduct of the war, but against the political errors and insincerities for which the fighting men are being sacrificed. On behalf of those who are suffering now I make this protest against the deception which is being practiced on them; also I believe that I may help to destroy the callous complacence with which the majority of those at home regard the continuance of agonies which they do not share, and which they have not sufficient imagination to realize.
