Should Open Access Include Open Software?

Posted in Open Access, Science Politics, The Universe and Stuff with tags , , , , on February 4, 2013 by telescoper

Very busy today, so just time for a quick post (and associated poll) about Open Science.

As you all know I’ve been using this blog for a while to bang on about Open Access to scientific publications. I’m not going to repeat my position in detail here except to say that I’m in favour of Open Access but not at the immense cost envisaged by the Finch Report.

I thought however that it might be useful to float some opinions about wider issues related to open science. In particular, the question that often troubles me is that is open access to scientific results actually enough, or do we have to go a lot further?

I think an important aspect of the way science works is that when a given individual or group publishes a result, it should be possible for others to reproduce it (or not as the case may be). Traditional journal publications don’t always allow this. In my own field of astrophysics/cosmology, for example, results in scientific papers are often based on very complicated analyses of large data sets. This is increasingly the case in other fields too. A basic problem obviously arises when data are not made public. Fortunately in astrophysics these days researchers are pretty good at sharing their data, although this hasn’t always been the case.

However, even allowing open access to data doesn’t always solve the reproducibility problem. Often extensive numerical codes are needed to process the measurements and extract meaningful output. Without access to these pipeline codes it is impossible for a third party to check the path from input to output without writing their own version assuming that there is sufficient information to do that in the first place. That researchers should publish their software as well as their results is quite a controversial suggestion, but I think it’s the best practice for science. There isn’t a uniform policy in astrophysics and cosmology, but I sense that quite a few people out there agree with me. Cosmological numerical simulations, for example, can be performed by anyone with a sufficiently big computer using GADGET the source codes of which are freely available. Likewise, for CMB analysis, there is the excellent CAMB code, which can be downloaded at will; this is in a long tradition of openly available numerical codes, including CMBFAST and HealPix.

I suspect some researchers might be reluctant to share the codes they have written because they feel they won’t get sufficient credit for work done using them. I don’t think this is true, as researchers are generally very appreciative of such openness and publications describing the corresponding codes are generously cited. In any case I don’t think it’s appropriate to withhold such programs from the wider community, which prevents them being either scrutinized or extended as well as being used to further scientific research. In other words excessively proprietorial attitudes to data analysis software are detrimental to the spirit of open science.

Anyway, my views aren’t guaranteed to be representative of the community, so I’d like to ask for a quick show of hands via a poll…

…and you are of course welcome to comment via the usual box.

Switching Allegiances

Posted in Biographical, Education, Football, Rugby with tags , , , , , on February 3, 2013 by telescoper

So here I am, then, in the office on a Sunday afternoon,which I suspect is going to be a pretty regular occurrence for the foreseeable future. I mainly came in to sort out papers for tomorrow’s Senior Management Group meeting, which will be the first such meeting I’ll be attending in my new capacity. I have managed to prepare for it in fine style by losing my diary, which isn’t a very good start to my career as any kind of manager.

Yesterday was taken up with flat-hunting which, if all turns out well this time, was successful. I also had time to watch a bit of the opening match of the Six Nations Rugby between Wales and Ireland. For the last five years or so I’ve always been in Cardiff for Wales’ first home game of the competition, although I’ve never actually managed to get a ticket for the match. It felt a bit strange not being there anyway. It has to be said that Wales were pretty chronic in the first half, going into the break at 30-3 down, but they recovered in the second half and it was quite an absorbing match all considered. Ireland’s excellent defence held off a spirited Welsh comeback and Ireland won 30-22.

Although I’ve lived in Wales for a while, and have enjoyed the match-day atmosphere in Cardiff, I’ve never switched allegiance from England as far as rugby is concerned. Later on yesterday England beat Scotland in their opening match of the Six Nations, showing quite a bit of flair in doing so but also making quite a lot of mistakes. The 38-18 scoreline flattered England, I felt, and they’ll have to up their game a lot if they’re going to match Wales’ Grand Slam last season.

Football is another matter in which allegiances are difficult to change. Many’s the time I’ve thought of giving up being a Newcastle United supporter but I’ve never managed it. I disapprove of people who think they have an option concerning which team to support, actually. I was born in Newcastle therefore I support Newcastle United. That’s the end of it. We all have our cross to bear. Anyway, yesterday brought an unexpected ray of sunshine into a gloomy season for the Toon with a 3-2 victory over Chelsea. Following a first away win of the season against Aston Villa last week it may even be possible that they’ll avoid relegation. Perhaps.

Switching allegiances between universities is almost as difficult. In today’s academic world we’re supposed to think of higher education as a marketplace in which different institutions compete for funding for both teaching and research. I’ve never felt comfortable with the idea that opening up higher education to “market forces” is in anyone’s interests. Certainly on the research side, there are so many collaborations between groups in different universities that cooperation is more the rule than competition although, as with any rule, there are exceptions. Friendly rivalry is as good a thing in higher education as it is in football, but anything more serious than that can only be justified in the case of Sunderland.

The Rolling English Road

Posted in Poetry with tags , , on February 2, 2013 by telescoper

Before the Roman came to Rye or out to Severn strode,
The rolling English drunkard made the rolling English road.
A reeling road, a rolling road, that rambles round the shire,
And after him the parson ran, the sexton and the squire;
A merry road, a mazy road, and such as we did tread
The night we went to Birmingham by way of Beachy Head.

I knew no harm of Bonaparte and plenty of the Squire,
And for to fight the Frenchman I did not much desire;
But I did bash their baggonets because they came arrayed
To straighten out the crooked road an English drunkard made,
Where you and I went down the lane with ale-mugs in our hands,
The night we went to Glastonbury by way of Goodwin Sands.

His sins they were forgiven him; or why do flowers run
Behind him; and the hedges all strengthening in the sun?
The wild thing went from left to right and knew not which was which,
But the wild rose was above him when they found him in the ditch.
God pardon us, nor harden us; we did not see so clear
The night we went to Bannockburn by way of Brighton Pier.

My friends, we will not go again or ape an ancient rage,
Or stretch the folly of our youth to be the shame of age,
But walk with clearer eyes and ears this path that wandereth,
And see undrugged in evening light the decent inn of death;
For there is good news yet to hear and fine things to be seen,
Before we go to Paradise by way of Kensal Green.

by G.K. Chesterton (1874-1936).

..and hello from Sussex!

Posted in Biographical with tags on February 1, 2013 by telescoper

Well, nearing the end of my first day in my new job at the University of Sussex, I can safely say that I’m more than a bit knackered. I’ve had a day filled with meetings as well as devoid of lunch. On the other hand I did manage to get the keys to my new office and, after some fiddling about, am now connected to the interwebs. They’ve even given me a nice new badge in case I forget who I am.

I didn’t get to leave Cardiff yesterday until later than I’d imagined I would and then managed to miss the train and had to wait an hour in Cardiff station. In the end I didn’t make it to my temporary lodgings until well after 11. I crashed out and slept like a log, and only just managed to drag myself out of bed to get to the campus in time for the first meeting.

My new office is very nice, although it looks a bit empty at the moment because all my boxes are still in Cardiff awaiting the attentions of hunky removal men. Here’s a picture taken yesterday by Dan Read in my old office…

..having finished packing I was about to add the final touch and clean my whiteboard, but I was persuaded that it’s such a work of art that, far from cleaning it off, I should actually sign it. So I did. No doubt it will be cleaned off soon, if it hasn’t been already.

Anyway, a weekend in Brighton now beckons which I’m going to start by doing down the pub for a pint, which may be the first of many…
