What is a good abstract?

In this article I will discuss abstracts for scientific papers and articles on art and technology.

There are probably many people better qualified to write this post than me, but as a regular reviewer for journals, conferences, grant applications, books etc. I guess it really matters to some people what I am looking for in an abstract, even if I am only one of many reviewers, even if my opinions are unconventional (for instance in the arts). So, what do I think are the properties of a good abstract?

I think a good abstract is (i) informative, (ii) clear and (iii) succinct. Obviously these aren't mutually exclusive properties, they are closely related. To be informative, tell me what I need to know. More on that in a second. To be clear, avoid jargon and keep terminology simple. Avoid references to other material (keep that for the introduction/background). The abstract is not post-modern poetry. Please explain yourself as simply and clearly as you can to engage as many people as possible. If you want people to read your paper, you must be understood by them from the beginning. To be succinct provide an overview but no detail, don't waffle.

What is needed for an abstract to be informative? Tell me directly what you have done. Tell me why you did it and convince me that it is important. Then tell me how you did it - briefly! This is the abstract, not the method/approach so keep it short. If the technique you used is well-known just name the technique. If the technique is related to a well-known technique, just name the technique and say that you used a custom or previously published variant of it. Lastly, tell me your conclusions, but just the main findings. This isn't a mystery novel. The reader mustn't be kept guessing until the Results section. Please include this information upfront.

That's it. I hope that isn't too much to ask. I must remember these guidelines myself next time I write an abstract.

cycling and sponsorship - pinarello and specialized comparison

Cavendish has a personal deal with Nike, while Sky's kit is supplied by Adidas, and Cavendish prefers a Specialized bike but Sky has a contract with Pinarello. [cyclingnews] It is complicated when you have people paying you buckets of money to use their stuff, and other people paying to use different stuff. Its tough when you don't want to use the stuff you are paid to use because it is not right for you.

So what's a rider to do? I wouldn't know as I have never been paid to use bike equipment before (although of course I am expected to wear my club racing kit when I compete... which I do!) But of course I have been asked to do things, by my employer even, that I personally felt were against the best interests of that same employer. What's a guy to do? When personal ambition is involved – such as in your own pride in winning a race – or (in my case) in teaching a subject well, or presenting an idea clearly, we are left with a conundrum. Tough call. If I were Cavendish I would take the Pinarello! :-)

mary shelley's moonlit window

"In August 2010, Professor Olson, two colleagues and two students went to Lake Geneva to discover when moonlight would have hit the windows, and penetrated the shutters, of Mary Shelley's bedroom." In this way, and by looking up their astro. tables, they aimed to date the birth of her famous tale, Frankenstein; or, The Modern Prometheus (1818) [The Guardian].

"It was a strong effort of the spirit of good; but it was ineffectual. Destiny was too potent, and her immutable laws had decreed my utter and terrible destruction" – wrote the poor Doctor in Shelley's tale (chapt 2).

If Shelley had her way, perhaps there would be no field of Artificial Life. If we took her text to heart, should we all stop now? Perhaps, like nuclear physics, the potential to make a mess of things is too great? And yet, here we are, pushing onwards in an effort to create life. Ahhh... what would a girl in her late teenage years know about the future of the world anyway?

melbourne's classic cycling routes

A quick chat in the (miniature) bunch this morning with some friends got me thinking. What are our hottest spots to ride on the road around here? Obviously my views are limited since I usually ride on the Eastern side of the city. Still, here are a few of my favourites (in no particular order). Some are well know and possibly spoiled by rowdy riders or traffic. Others are less well known and still have the rural charm.

  • The Dandenongs (Basin to Sassafras but also the countless roads over the back)
  • Kinglake climb (St. Andrews to Kinglake)
  • Mt. Pleasant Rd. (Eltham)
  • Hussey's Lane (Park Orchards)
  • Beach Rd. (Brighton to Mordialloc)
  • Cottles Bridge - Strathewen Rd. (Cottles Bridge to Strathewen. Doh.)
  • Yarra Boulevard (Kew and Burnley)
  • Beverley - Banyule - Henty - Cleveland - Bonds - Old Eltham Roads (Rosanna)
  • The Esplanade (Mornington to Safety Beach)
  • Clintons Rd (into Smiths Gully)
  • The Alps (Falls Creek, Mt. Buffalo, Mt. Hotham)
  • The Great Ocean Rd. (It is long and almost entirely fabulous)
I am sure I have forgotten many, but that is a start!

bicycle headlight - moon X-power 500 review

I have recently taken to early starts at o'dark thirty as my previous post highlights. As I have been riding on unlit country roads, a proper headlight was in order. In my case, the Moon X-Power 500 – that's a 500 lumens headlight for a bike! I know brighter lights are available, but really, are they necessary for cycling? Perhaps for mountain bike riding in the dark?

The 500 is ample bright for unlit roads. So bright in fact that I have been riding it on its "standard" setting of 240 lumens (made from a selection of "Full after-burners engaged", High, Standard and Low) unless its really pitch black. The beam is a good design with ample reach and diffusion to provide a nice balance between seeing ahead at speed and around to give a sense of the space beside you. When the sunlight makes its debut, I switch to Flashing mode which, at a reported 380 lumens, is blindingly bright. Retro-reflective street signs flash at me from a kilometre away when I have this mode on. In pitch black, flash mode is disorienting. The whole world seems to strobe and the mode makes me dizzy.

The power/mode button is a flush press fit, not the best when wearing full gloves but manageable. I would also like a mode indicator on the light or a switch that shows by its position the current mode. It is hard to tell which mode you're in and since the battery life is reduced significantly in the brightest modes, I would like to be able to tell at a glance that I am in a lower intensity mode as I trundle along. The unit does flash red LED at you when it is running low on juice. Switching to a lower power mode can save you from complete blackout for awhile.

The mounting bracket for handlebar use is sturdy but the "quick-release" is not quick. You have to screw in the bolt and use the lever just to cinch it down. There's no way to get the quick-release to work as one since you can't get the clamping loop over the bars if the screw is in. Still, this is a minor quibble. The bracket clamps to my oversize road bars with no problems and the light is slid into place on (or removed from) the bracket with the press of a catch. The pitch and yaw of the headlight are adjustable easily.

A helmet mount (velcro strap and bracket) is included with the kit. I haven't tried it and I am unlikely to do so. There's nothing I hate more than a fellow cyclist looking me in the eye and blinding me with their head-mounted laser beam as they wish me good morning. I bet motorists hate it too. This system (IMHO) has no place on the road.

The light comes in a funky carry case with charger and USB cable. It charges okay in a few hours from computer USB or the wall USB charger provided. Only time will tell how many recharge cycles I get from the unit. It doesn't take a standard AA but instead a specially built NiMH battery enclosure slides inside the light. Hopefully a replacement is available when it comes time! Otherwise I would be really annoyed.

Be seen. Be safe.

august concludes with a ride in the dark

Wow! Its already the end of August. The days are getting longer and milder. A few days ago, in an effort to get out on the real bike (instead of an indoor trainer), I left at 5.30am for a couple of hours of riding down Melbourne's famous Beach Road. A few things I noticed that are worth considering when riding in the dark:
  1. No matter how cool your favourite black kit is, don't wear it in the dark. Death wish?
  2. At 5.30am on a Sunday the main roads are almost completely free of traffic.
  3. At 5.30am on a Sunday the main roads are better lit than the back streets.
  4. The new front LED lights are REALLY bright. Get one.
  5. Riding in the dark in a bunch turns you all into part of a blinking flashing Christmas tree that can be seen for more than a kilometer. Good idea!
  6. Its eery and lovely on a still morning down by the beach. Try it some time. I will see you there!

alexander calder

I just discovered online this image by Calder... Six Day Bike Race, 1924, oil on canvas, 30 by 30 inches, Calder Foundation, New York. Nice and seedy, just like the 6 day races. Was this a conscious inspiration for the work in Paris by Alexandre Ganesco, Les "Six Jours", 1930!? The two have a lot in common. Maybe that is just the subject matter. To do: attend smelly, noisy 6 day race in Belgium.
