Anonymity Revisited

Posted in Biographical with tags , , , , on February 19, 2012 by telescoper

I’ve a lot to do today – a backlog of crosswords to clear, for one thing – so I’m going to indulge in a bit of recycling. I posted some years ago about internet anonymity in the wake of a spate of abusive comments on this blog. I’m not sure whether a spate can have a wake, actually , but I’ll press on regardless.

Today there’s a typically insightful piece by David Mitchell in the Observer on a similar topic, cleverly juxtaposing St Valentine’s Day (where anonymous messages are welcomed) with the rise of the internet troll whose messages are of a distinctly unwelcome character. I think he gets it just right (as usual):

Like love, hate is something that makes us go red in the face. It’s safer expressed covertly lest it be rejected.

I’ve encountered more recent – and much more serious – examples of what people are prepared to get up to under the cover of anonymity. I’ve refrained, and shall continue to refrain, from describing them in detail here. Some of my friends – and some of my students – know what I’m talking about. All that has now stopped, but if it starts again the gloves will definitely come off.

These experiences have confirmed my distaste for anonymity. I will therefore persist with my policy of requiring a proper email address for commenters on this blog. The address will not be revealed to the public, of course, and commenters are free to use pseudonyms if they wish. I can understand that people might want not to be identified if they say something controversial, especially if it amounts to whistle-blowing. However, if you wish to express opinions on my blog I think it’s not unreasonable for me to know who you are.

Anyway, the following is taken from an old post (from 2009) which arose from a story in the press at the time.

–o–

It’s not often that I blog about celebrity tittle-tattle – I have no idea who most “celebrities” are these days anyway – but a little story in last week’s Guardian online caught my eye. I thought I’d mention it here because it raises some interesting issues.

The story is of a fashion model, Liskula Cohen (whom I’d obviously never heard of). It appears that an anonymous blogger (with the charming pseudonym “Skanks”) wrote some derogatory remarks about said Ms Cohen on a website. The latter decided to sue for defamation, but that was difficult because the identity of the blogger wasn’t known. Cohen therefore went to court in an attempt to compel Google to identify the person responsible. She won that case, and duly found out that the blogger was a person called Rosemary Port (who I’d never heard of either). Anyway, to cut a long story short, Ms Cohen dropped her original lawsuit but Ms Port is now suing Google for handing over her real identity…

Of course the story is all a bit childish, but there is a serious question behind it, namely to what extent one has a right to anonymity. I’m not at all sure what the law says on this or what it should say, in fact, especially when it comes to the internet.

In Britain we don’t have identity cards (not yet anyway), so there’s a sort of de facto right to anonymity there. However, with the increasing levels of surveillance and state intrusion into people’s lives, that is changing. The  issue generated by the story above, however, is how the right to anonymity extends into the blogosphere (or the internet generally) rather than how it applies in real life.

Some blogs I know are anonymous but I happen also to know who writes them. I presume the authors have reasons for wishing to conceal their identities so I wouldn’t dream of revealing them myself. However, these are all sites run by reasonably civilised people and it’s very unlikely that any of them would use their anonymity to engage in abusive or defamatory activities. If one of them did, I wouldn’t have any qualms at all about exposing their identity, but I’m not sure whether that would be a legally acceptable course of action.

But anonymity still makes me a  bit uncomfortable. In academic life we come across it in the context of refereeing grant applications and papers submitted to journals for consideration. Usually the default is for referees to remain anonymous is such situations. Most referees are conscientious and if they have criticisms they are usually presented politely and constructively. There are, however, some exceptions. Fortunately these are few and far between, but there are some individuals who take the opportunity provided by anonymity to be downright abusive. Us old hands have sufficiently thick skins to brush such attacks off, but vitriolic comments made on papers written by inexperienced scientists (perhaps even research students) are completely out of order. This probably wouldn’t happen if referees didn’t have the right to remain anonymous. On the other hand, having your identity known might make it difficult for some  to write critically of, say, the work of more senior scientists. Perhaps the answer is to retain anonymity but for the journal editor, for instance, to monitor the reports produced by referees and reprimand any who transgress.

Going back to the original subject of blogs, provides me with an opportunity to describe some of the behind-the-scenes issues with running this blog. In the beginning I decided to have an open comment policy so that anyone and everyone could comment without any form of intervention. That turned out to be a disaster because of the numbers of automatically generated  SPAM comments that clogged up the boxes. I therefore switched on a SPAM filter so it could veto obvious garbage, but otherwise kept an open policy. The alternatives offered by WordPress include one that requires all comments to be from people registered at the site (which I thought would probably be a deterrent to people only wanting to comment on the odd post). Another option is to maintain a blacklist which treats all messages from persons on the list as SPAM. It’s also possible to block all comments entirely, of course, but I enjoy reading most of them so I think it would be a shame to do that just because of a few breaches of netiquette.

All went fairly well and I only had to ban a couple of individuals for abuse. However, over the course of the year I have received a steadily increasing number of crudely abusive comments (of a personal nature) from various anonymous sources. These are mostly depressingly puerile and they don’t affect me much but I find it very disconcerting to think that there are people sitting out there with nothing better to do.

Since WordPress notifies me every time a  comment is posted, it is quite easy to remove this junk but I found it very tiresome (when there were several per day) and eventually decided to change my policy and automatically block comments from all anonymous sources. Since this requires a manual check into whether the identity information given with the comment is bona fide, comments from people who haven’t commented on this blog before may take a little while to get approved.

There are still comments on here which appear anonymous (or with a pseudonym), but these are from people who have identified themselves to me with a proper email address or who the software has identified through their IP address or information revealed by their web browser (which is probably more than you think…). I’m happy for people to comment without requiring they release their name to the world, and will do my best to ensure their confidentiality, but I’m not happy to publish comments from people whose identity I don’t know.

If you’re interested, as of today this blog has received 4105 comments in total, but only 1747 have been published. The rest were either SPAM or abuse. UPDATE: as of today, 19th February 2012, 11880 comments have been published and 86703 rejected

Am I denying freedom of speech by rejecting anonymous comments? I don’t think so. If you want freedom of speech that much, you can write your own blog (anonymous or otherwise). And if every sight of this blog makes you want to write abusive comments, perhaps you should exercise your freedom not to read it.

I’d be interested to know from any fellow bloggers if they have the same problems with abusive comments. If not, perhaps I should start taking it personally!

More generally, I will not accept anonymous comments on the subject of the anonymity of comments, but any other contributions are welcome via the box.

Unless you’re banned.

Men at Forty

Posted in Poetry with tags , , on February 18, 2012 by telescoper

Men at forty
Learn to close softly
The doors to rooms they will not be
Coming back to.

At rest on a stair landing,
They feel it moving
Beneath them now like the deck of a ship,
Though the swell is gentle.

And deep in mirrors
They rediscover
The face of the boy as he practises tying
His father’s tie there in secret

And the face of the father,
Still warm with the mystery of lather.
They are more fathers than sons themselves now.
Something is filling them, something

That is like the twilight sound
Of the crickets, immense,
Filling the woods at the foot of the slope
Behind their mortgaged houses.

by Donald Justice (1925-2004).

Offa’s Irrelevance

Posted in Education, Politics with tags , , , , on February 18, 2012 by telescoper

There is leader column in today’s Grauniad about the University entrance system which, it rightly says, is “in a mess”. It’s good to have discussion of this subject in the press but the problem is that, in the typical fashion of a Guardian editorial, this piece is worthy in sentiment but misses the basic point entirely.

The reason for visiting the theme of student access to Higher Education at this point is the kerfuffle surrounding the appointment of the next boss of Offa – the Office For Fair Access – a quango set up by the previous New Labour Administration to ensure that universities do everything possible to encourage students from diverse backgrounds to go to University. A laudable aim, but doomed to failure at the outset. The reason for this is that the system of post-16 education is fundamentally flawed (as it clearly is), then no “Access Czar”, however powerful, can hope to accomplish the vast amount of reverse-engineering required to ensure that universities can cope with failures earlier in the system. Just look at how useless Ofgen has been at regulating energy prices, for example, another case of a flawed system impervious to a quango’s attempts to improve it.

The point which is missing – and which our political masters and the educational establishment alike refuse to acknowledge – is that GCE Advanced Levels are neither an adequate preparation for University study nor a reliable way to select applications on their suitability for a given course. People who actually work in Higher Education know that this is true, but the Power That Be won’t recognize it and instead maintain that A-levels constitute a “Gold Standard”. The fact is that in the hands of Examination Boards that compete for business by lowering their standards, A-levels have become nothing other more than base metal, and tarnished to boot.

If I had my way we wouldn’t use A-levels at all to determine whether a student gets a place at their chosen University. I’ve seen so many examples of absolutely brilliant students who entered Cardiff University with modest A-levels – often having not got into their first choice institution and coming to us through the clearing system – that I’m sure there are many excellent potential students out there who didn’t get into university at all. The other side of the coin is that many students who get top A-level grades across the board don’t flourish at university at all. It’s my experience that A-levels are no guide at all to a student’s ability to do well on a course.

If you don’t believe this, then ask yourself the following question. If Cambridge only takes students with grade A* at A-level, why don’t all their students end up with First Class Degrees?

Any attempt to fix the severe problems that beset the student entrance system must begin with a recognition that this is where the fault lies.

So what’s the solution? I think it is to scrap A-levels entirely, and give the system of pre-university qualifications over to the people who actually know what students need to know to cope with their courses, i.e. the universities. There should be a single national system of University Entrance Examinations, set and moderated by an Examination Board constituted by university teachers. This will provide the level playing field that we need. No system can ever be perfect of course, but this is the best way I can think of to solve the biggest problem with the current one. Not that it will ever happen. There are just too many vested interests happy with the status quo despite the fact that it is failing so many of our young people.

Good luck to whoever it is that takes over at Offa, but it won’t make any difference who’s on the bridge because the ship is already on the rocks.

Myself in Pictures

Posted in Biographical on February 17, 2012 by telescoper

A lot of these “occupation” pictures are going around on facebook, so I thought it would be fun to post those that encapsulate myself most accurately…

I’m not really an astronomer, but this is as close as I could get…

A few obvious inaccuracies in the next one but still pretty close to the truth!

The last one isn’t entirely accurate in my case – I’m more of a Port and Stilton type of chap…

And here’s one for the students…

Innovations

Posted in Science Politics with tags , , on February 16, 2012 by telescoper

Moaning about science politics, especially with regard to funding, is one of the recurring themes on this blog. The UK government administers science policy through the Department for Business, Innovation and Skills (better known as BIS). Unfortunately I can’t think of that name without harking back to the good old days of the Innovations Catalogue (shown left). I was shocked to discover that this met its demise as long ago as 2003 but in its time it was comedy gold. Packed full of palpably useless gadgets – who could possibly forget the vibrating fur-lined golf club cover? – it was all the more hysterical for  that fact that it was clearly deadly serious. When I’m Sorry I Haven’t A Clue tried to lampoon the Innovations Catalogue,  the results struggled to be as funny as the real thing, although I do remember Willie Rushton’s combined cigarette lighter and nasal hair remover…

It seems that the Innovations people made one big mistake that cost them their business: the stuff they sold was dirt cheap. Subsequent experience has taught us that if you want to persuade people to buy useless gadgets, you have to make them expensive. No tat sells like expensive tat…

Anyway, having thus established the theme of Innovation, let me now explore a variation. Websites.

Over the past few weeks I’ve noticed a number of changes to websites I use. Last week I noticed that Twitter had been revamped. The first impression I got was that all my tweets were on the right hand side of the screen instead of the left. Not a drastic alteration, though as a man who is fully in touch with his inner Luddite I find even that level of change hard to cope with. More perturbingly I later saw that the button for searching for mentions of your username (for those of you who aren’t twits twats twerps tweeters, this was marked “@” because all twitter names begin with that character) is no longer labelled “mentions” but “connect”. Huh? Connect with what or whom? Likewise the “activity” tag is now called “discover”. Why it was decided to change the names from something descriptive to something non-descriptive is beyond me, but it’s probably what passes as “innovative” in the world of web designers.

I’ve got nothing against web designers in general, and I think some websites are absolutely wonderful in both content and style. This one, for example. However, there are some who seem to have been put together by people on a mission to the make the design so impenetrable that it’s impossible for anyone to find any content at all.

A major leap in this direction has recently been made by the BBC. A while ago they introduced a new home page, which has virtually no information on it, but lots of graphics. After vociferously negative responses from users of the BBC Website, i.e. the public, the person in charge responded by saying that the changes were needed in order to make the site more distinctive. I freely admit that it is distinctive, but its main distinction is that it is poor.

Now I’ll grant that page layout and style is a matter for personal taste so there will be others out there who like the new BBC Webshite. That’s fine. What’s less forgivable is that the quality of service has also deteriorated and that is an objective fact. Here’s an example.

On the old BBC website you could set your location, with the result that the homepage would give access to local news, local TV and radio listings, and so on. You also automatically got weather information for your chosen location. Now you can still set your location on the homepage, but if you click on the new “weather” page your location is automatically set to London. Every time you log on, and want to check the weather, you have to type in your location by hand. Unless you live in London, of course, which is presumably why the web hacks didn’t worry about this.

I’m no expert, but it shouldn’t have been beyond the wit of even the most lowly web designer to pass information about location from one page to another within the same site. But who cares about whether the service is better for the user, as long as it’s distinctive….

I suppose the point of this post – if there is one – is that we shouldn’t be too respectful towards innovation for innovation’s sake. Not all innovation is good.

You might think that adage applies also to what goes on in BIS, but I couldn’t possibly comment.

Notional Student Survey

Posted in Education with tags , , , on February 15, 2012 by telescoper

The first couple of weeks of this term have been hectic, primarily because of our new-style Consolidated Astronomy Grant Proposal to the Science and Technology Facilities Council which has just gone in with a deadline of tomorrow, but also because I’ve just started teaching Nuclear Physics for the first time, a subject I know absolutely nothing about about which I am a little rusty. I’m only just keeping up with the lectures and problem sheets, and am glad the students are being patient. So far, anyway.

I had only just got back on schedule with this morning’s lecture when I find that tomorrow I have to give up part of the next one by advertising the National Student Survey and encouraging my third-year class of 85 or to participate; the NSS taking place over the next few weeks.  Apparently the rate of return by Physics students is especially low and the University is keen that it should increase. For some reason I’ve been singled out as a suitable person to persuade our third years to provide their input and have been given a special powerpoint presentation to show to encourage all eligible  students – i.e. students in their final year – to complete the survey, so I thought I’d share it here in order to spread the message as widely as possible. I’m not sure what fate awaits me if our rate of return doesn’t improve…

It doesn’t take long to complete – it’s all online – so I hope anyone reading this will take the time to respond. That’s not just for Cardiff Physics students – although I know a few of them do read this blog – but also for students elsewhere in the United Kingdom. If you don’t tell us what you think we don’t know what we could be doing better, so please fill it in. You know it makes sense.

The NSS have also given me a boomerang. I think it’s meant to symbolize a high rate of return. Or something. I may attempt to throw it in tomorrow’s lecture, although I’m not sure that’s allowed on Health and Safety grounds. At least it will provide a bit of light entertainment before I launch into the deep joy that is the semi-empirical mass formula.

P.S. Coincidentally, there’s a nice a typically snarky piece about the NSS by Laurie Taylor in a recent Times Higher.

The SKA Propaganda Machine

Posted in Astrohype, Science Politics, The Universe and Stuff with tags , , , , on February 14, 2012 by telescoper

I’m a big fan of the Square Kilometre Array, a proposed new radio telescope that will revolutionize our understanding of many aspects of astrophysics.

I’m somewhat less keen on the intense lobbying being carried out on behalf of Australian astronomers in advance of the decision whether to site it in Australia or South Africa. The campaign is being orchestrated by a PR organization called Ogilvy and Mather who are making full use of social media to promote the Australian case.

Last week I was invited by email to attend a “webinar” (whatever that is) about the SKA, an invitation that I quietly ignored. Today I got a follow-up email from a person described as a “Digital Analyst” offering me the chance to “interview Dr Brian Boyle or Dr Lisa Harvey Smith”. They also sent me the following “infographic” (i.e. a picture) showing the case for siting the SKA in Australia, which they thought would be of interest to “my blog readers”.

Well, you can call me old-fashioned but I think there’s something a bit distasteful about engaging a glorified ad agency to lobby on behalf of one party in a discussion that should be resolved on purely scientific grounds. I wonder how much it cost, for a start, but I’d also have hoped scientists would be above that sort of thing anyway. Sign of the times, I suppose.

Anyway, even if the digital analysts at Ogilvy will be happy that I’ve shown their infographic, perhaps they might now realize that spin can work in two different ways…

My Funny Valentines

Posted in Jazz with tags , , , , , , , , on February 14, 2012 by telescoper

I’m not really into all this St Valentine’s Day nonsense (meaning: “I never get any cards”), but at least it provides me with an excuse to post three versions of the great Rogers & Hart ballad  My Funny Valentine.

The first is by the great Miles Davis Quintet featuring Miles Davis on trumpet, Wayne Shorter on tenor sax, Herbie Hancock on piano, Ron Carter bass and Tony Williams on drums. This was recorded live in Milan on October 11th 1964. There’s a slight distortion in the sound in the form of a pre-echo, which is a bit eery, but I still think it’s a marvellous performance.

And if Miles Davis isn’t your cup of tea, here is something completely different. It’s by Julie London, but very late in her career in 1981 when she was 55. Her voice was much smoother in her heyday in the 1960s, but I love the smokey sound of this very characterful rendition. By ear I’d say the bass player on this is Ray Brown and the guitar is Barney Kessel, both of whom (like Julie London herself) are no longer with us.

Last one up is a miracle of joint improvisation between the great Bill Evans on piano and Jim Hall on guitar, the sort of music that mere mortals can only dream of…

Planck Time

Posted in The Universe and Stuff with tags , , , , , , on February 13, 2012 by telescoper

Only time for a quickie today, as I have a busy afternoon in store at a meeting in the Graduate College (zzz…). Today there has been a press conference in Bologna about latest results from the ESA experiment, Planck. Here’s a picture taken at the press conference by roving reporter astrophysicist Mike Peel.

I gave a talk in that room once, actually, although there weren’t any press people there on that occasion.

Although it will be some time still before the full cosmological results from Planck are released to the public (and researchers outside the Planck Consortium), the press conference covered a number of new and interesting discoveries, particularly about our own Galaxy. You can read about them at the  ESA Planck website here and on the UK Planck site (hosted at Cardiff University) here.

Among the results are beautiful maps of microwave emission from cold molecular gas (e.g.  carbon monoxide) from sources inside the Milky Way:

Planck wasn’t specifically designed to detect CO emission, but it’s part of the “foreground” radiation that must be understood and modelled on the way to extracting cosmological information from the results.

Another exciting item is the Galactic Haze that emanates from the central regions of the Milky Way, which you can see in this picture poking out from behind the “mask” that is used to blank out emission from the Galactic Plane (i.e. the disk of our Galaxy).

The origin of this haze, which appears to be consistent with synchrotron radiation but with quite a hard spectrum, is not known and is the topic of much discussion in the astrophysics community.

For more information, see the main Planck site or, with more technical details, here.

It’s that time again…

Posted in Music, Rugby with tags , , on February 12, 2012 by telescoper

Today was the day for the first home game of the RBS Six Nations for Wales, so Cardiff was absolutely buzzing with that special atmosphere that only rugby and an influx of 80,000 people into a city with a population of 325,00 can bring. I was out and about earlier on but had to watch the game on TV as I lack the wherewithal to get tickets for occasions of such immensity. Wales were red-hot favourites for this game, and won comfortably enough in the end against Scotland although the game was closer than the 27-13 scoreline might suggest; Scotland had a try incorrectly disallowed, which might have made all the difference. The Scots fans also played their part, some of them camping out in the park near my house in the freezing cold for two nights before today’s game, and offered a fine rendition of Flower of Scotland before the kick-off. But there’s something special about the Welsh National Anthem on days like this. I’m glad they’ve dispensed with the professional pop singers that they’ve sometimes used to lead the singing. Wales is a nation that doesn’t need to pay people  to sing for it…
