Lit Review

It always strikes me how difficult writing a literature review can be. Sometimes it feels like walking through a maze of tunnels, with nothing more than a laser pointer to find your way out. And when you get out, you're not even sure whether you're at the right exit. So you just keep on walking, flashing your pointer around, trusting that this seemingly inefficient process will eventually find the right way forward.

It might all sound a bit dramatic, but as I sit here at my desk with a mountain of papers in front of me to potentially include in my literature review, its the closest analogy I can come up with. Its a funny mix of feelings though. My time frame is pretty tight for getting things done, so I am definitely feeling the pressure to read less and write more. On the hand, I am reading these papers with a significantly heightened sense of context and purpose. Frankly, this stuff has never seemed so interesting as it does now. In some respects, and perhaps a bit embarrassing to admit, I am only just beginning to understand what my PhD is really all about, and where it fits. Problem is, I don't have the time for this sort of academic indulgence. I just need to get this thesis written, and so long as the reviewers are convinced I know what I'm on about, then that's all that really matters for the moment.

bringing it to the people

It's been a hectic couple of days, but very rewarding. Yesterday I had the privilege of speaking at the 2008 ACT Intergenerational Forum, an annual community-based forum (ie not a an academic conference) organised and run by PhD students in the general field of ageing research. You'd be forgiven for wondering how the hell my research in computer vision relates to ageing. In a sense, I would like to think my research relates to many things, however, my recent focus has been on how I might be able to adapt my work with insect-inspired vision techniques for navigation to the task of assisting with hazard perception in older drivers. The research out there suggests we do lose some ability to perceive potential hazards as we get older. The forum was a great chance to talk directly with people who might be consumers of such technology, so I got quite a lively array of questions after my talk.

The other consequence of my talk was a little bit of media attention, including a story in ABC News online: Researcher designs insect-inspired navigation system, and a couple of radio interviews, including this one with
ABC News Radio (mp3)

So it has been quite a busy , indeed all-consuming, couple of days. Suddenly thesis writing feels like a bit of an oasis from the madness ... nice to have these distractions occasionally though .. particularly ones that remind you why you're doing this research in the first place.

28 weeks and counting

28 weeks and counting, but who's counting ? well, I certainly am. We are well and truly into the third trimester, and bub is starting to make himself known. For one, Aff's huge! For two, a fair bit of seismic activity on the surface has become apparent, suggesting the little tacker is developing a keen interest in judo. Early on in the pregnancy, the thought of us actually being pregnant was fairly incomprehensible given the lack of any obvious indicators. Things are a little different now. Do I feel ready ? Hell no! Can I comprehend what's about to happen ? I think so. There is no doubt evolution knew what it was doing when it gave us 9 month pregnancy terms. I suspect many mothers who have gone through particularly rough pregnancies will disagree. For me however, 9 months seems to be about the right amount of time to get my head right (and my thesis). No question, I am really looking forward to being a Dad, and all that it brings. For now though, I am really glad to have the time I have to get things in order, and to take a moment to enjoy being without such a daunting responsibility as raising children.

rate cuts

So the RBA has slashed interest rates by 1 percent. Only months ago we were being told that no such thing would happen until downward pressure was being applied to inflation. Now the view appears to be that a dramatic slow down in the economy will do that job for us, and so we say "fair thee well" to that little political hot potato. Surely recent events highlight the emptiness of the political debate surrounding "inflationary pressures", and the effect the Australian government has on interest rates. In a globalised economy, and conditions as they are, it is fairly safe to say that the government can neither help nor hinder such things .. at least within the marginal issues in which the debate gets bogged in. We should keep this in mind next time we hear Wayne Swan taking credit for an interest cut, or Turnbull blaming the government for an interest rise.

the way of the thesis

Indirectly, I've been writing this thesis for years. Every word added to an article or note scrawled out on paper, does contribute towards the final product. That's what you tell yourself anyway, and what you put on your application for extension form. I have to say though, nothing truly feels like thesis writing, except .. well ... writing a thesis.

There was no ceremony or event to mark the start of official thesis writing. It was simple really. I opened a blank file, and named it 'thesis.tex'. I then proceeded to copy and paste every digitised word I have ever written on the subject of computer vision. An hour later, I had added 120 pages of the most incomprehensible mish-mash to my empty thesis document, and so it began.

It is somewhat disconcerting that a month or so later, the number of pages hasn't really increased. On the other hand though, a hell of a lot more has gone into it. The process of adding new content, and then refining the words to say the most you can with as little use of the English language as possible is the way of the thesis. I know I will begin to hate this process, particularly when I realise there is nothing else left to do except write, but for the moment, it actually feels kind of good to be at this stage. Actually seeing it take shape, ever so slowly, and forming into something that represents the four years of work I have put into this is quite a motivator. Of course, having a baby due in three months, and desperately wanting to end student life and get a real income is another.

blogging again

OK, so it's been a little while. I wish I could point to some noble reasons for why like saving whales in the Southern Ocean, feeding the hungry in Africa, or installing Linux on my desktop, but basically, I got tired of writing. To be honest, I am not feeling particularly in the mood right now, and with my thesis writing ramping up a couple of gears, I do not expect to be writing a lot. On the other hand, these be interesting times in my life, so some sort of record of events, thoughts and activities seems like a good thing to do, even if infrequently.

So, since last post, what's been happening ? Well, for one, Aff and I have gone and made ourselves a baby. He (yes, he is a he) is not born yet, but we expect him to arrive sometime around late December. We're about 26 weeks in now, so over half way there. Aff is looking the part too! No more awkard "I think she's pregnant" looks. Now she just looks pregnant.

In other news, I am now in my last 6 months of my PhD. While I would love to have the thesis out the door by the time mini-macca arrives, this just ain't gonna happen. A full draft, however, is looking like a pretty reasonable goal. From my experience, and talking to others, one month is typically the time it takes to submit after completing a draft. Based on this, and assuming a couple of weeks off when the baby arrives, I have February marked as my thesis deadline. I actually have until the end of March, but I am not allowing myself the luxury of thinking I have this time. I need this thesis out of my life ASAP.

And then what ? well, that's another aspect of my life that has become a little interesting in recent times. I have started looking around, and have even turned down a non-academic position that was offered to me, a decision that wasn't easy as it forced me, perhaps for the first time, to really decide what I want to do when this PhD craziness is over. Basically, I have decided to continue with research, and pursue a post doctoral position. Hopefully there will be more to say about this in the coming weeks. For now, I can say that I am quite confident that I will have something - a feeling that can't be understated.

I could say a lot more about a lot of things. In the interest of "sustainable blogging" however, I'll leave at this, and hopefully add more soon.

It is good to be blogging again!

Three years

Ah yes, and so it has come, the email. When you embark on a PhD there is an initial flurry of interest on the part of the university, mainly to ensure you have paid all your fees, filled out your scholarship forms, and been told how to sit correctly in your office chair. They spend a bit of time explaining how this whole PhD thing works, drag in some senior students to tell you all about it, and then, nothing. You're on your own. Apart from the fortnightly bank statement telling you your scholarship payment has arrived, and an annual letter informing you that according to the university's records, you are indeed still a university student, that's about it. No "hi, how's it goin'?", or "what have you been up to?" emails. Not even a Christmas card. Nothing. Then, three years down the track, after all the trials and tribulations, journal club meetings, conferences, lab visits, seminars, pub sessions and introductory yoga classes, an email arrives.

Dear Chris,
remember us. We're the Australian National University and your time is nearly up! If you're a slack arse student who won't be finished in time, fill out this form to beg for our mercy.

yours,
ANU
ps. merry Christmas


You see, in theory, a PhD is supposed to take three years. There is a legend often told at the Uni house pub on Friday's, and in the tea rooms of many a research lab, that once upon a time, somewhere, a PhD thesis was submitted in three years. No one knows his or her name, or what the topic was, but I suspect they studied at The University of Fairy Land, where supervisors have inifinite time to talk with you, trained monkeys run your experiments, and ready to submit PhD theses grow on trees. The fact is, despite the university's admirable attempts to put some curry in the PhD sauce, and get students to complete quickly, very few achieve this. Why is this you ask ?

Well, for those not familiar with the wonderous world of the PhD degree, let me explain. A PhD in its classical form, has little to do with lectures, exams, lab classes, semesters, prescribed text books and to be honest, anything else you probably attribute with a university undergrad degree. It is a student, a desk, and the none too small task of coming up with something that prior to your work, was not known, designed, created or explained before. You do get some help though. A supervisor for one, who can be quite useful, although less effective as you progress and realise after a couple of years that you know more about your topic than they do (this is expected by the way). You also have hundreds of papers, articles and other forms of media that provide a seemingly endless supply of material that may or may not be related to what you're doing. Of course, the relevance and accuracy of this material varies, and so a significant amount of time is spent trying to sift through and find papers of use to you, while at the same time hoping not to find something so useful as to render your own work obsolete. It can be as frightening as it is enlightening.

The summary of all of this is that tangible outcomes can be few and far between, and in general, the structureless nature of the degree means much of the motivation to get work done, work that is often highly brain intensive and not particularly enticing on a Friday afternoon (or any afternoon for that matter), must come from within. Of course, choosing an interesting topic to begin with definitely helps this. Although, this is also akin to choosing a song you really like, and playing it over, and over, and over again ... for four years. Sometimes you just wish you could skip to the next track.

This probably all sounds very negative, but it is somewhat ironic that the one thing that causes much of the stress and pain associated with a PhD, is also the one huge motivator to keep going with it ... intellectual freedom. An academic once told me that he really envied his PhD students, and yearned for the time he spent as a PhD student (admittedly it had probably been at least twenty years since he completed his, giving him ample time to forget the pain). What he missed most was the opportunity a PhD offered to emerse himself so thoroughly, and without obstruction, in an intellectual interest. To spend day upon day researching a topic that genuinely excited him, with a real purpose, was a luxury he had not experienced to the same degree since. I remember telling myself I should talk to this guy more often - I hadn't felt this motivated since getting my pen license.

So three years in, and I am happy to say that I am still pretty excited about the work I am doing. Equally though, I have never been more motivated to get on with things, and get this thesis out the door. Like the vast majority of those before me, I will be applying for an extension, otherwise I would have to pull out the most productive February on record. I'm motivated, but not that motivated.

In any case, it's nice to hear from the University after all these years. I look forward to hearing from them again. Probably in 6 months time.
