Wakeham Review of STEM Degree Provision Graduate Employability and

Posted in Politics, Science Politics, Uncategorized with tags , , on May 20, 2016 by telescoper

About to embark on a weekend of examination marking, a desperate search for displacement activities reminded me of this important report by Sir William Wakeham (who happens to be the Chair of SEPNet, the South-East Physics Network, of which the University of Sussex is a member, so I get to call him Bill).

Apparently Bill’s report has been ready for some time but has been stuck on a shelf in Whitehall somewhere waiting to be released. Arcane rules about publishing government reports in the run-up to elections meant that it had to wait until after May 5th for publication.

Anyway, it was published this week (May 16th to be precise) and I encourage you all to read it. You can find the report and various annexes here. It has clearly been a complex task to make sense of some of the datasets used because they are incomplete and/or confusing, so inevitably some important questions remain unanswered. There are nevertheless clearly worrying signs for certain disciplines, as described in the Executive Summary:

Based on the accumulated evidence we have arrived at a list of degree disciplines where the graduate employment outcomes are sufficiently concerning for us to recommend additional targeted work. The STEM disciplines that the review has identified as being of particular concern are:
•Biological Sciences
•Earth, Marine and Environmental Sciences
•Agriculture, Animal Sciences and Food Sciences

I’m a little surprised that Biological Sciences appears in that list, because that is usually perceived as a burgeoning area, but it’s clear that some graduates in that area do find it more difficult to find employment than in other STEM areas. However, if you read the report in more detail you will see that there are many sub-disciplines involved in Biological Sciences and the picture isn’t the same for all of them. It does seem, however, that in some of the Biological Sciences, graduates do not have sufficient training in quantitative methods to suit the demands of potential employers.

There you go. Give it a read. Any comments?

If I Can’t Change Your Mind

Why do people still use Journal Impact Factors?

I don’t know either, but they should stop..

quantixed's avatarquantixed

I have written previously about Journal Impact Factors (here and here). The response to these articles has been great and earlier this year I was asked to write something about JIFs and citation distributions for one of my favourite journals. I agreed and set to work.

Things started off so well. A title came straight to mind. In the style of quantixed, I thought The Number of The Beast would be amusing. I asked for opinions on Twitter and got an even better one (from Scott Silverman @sksilverman) Too Many Significant Figures, Not Enough Significance. Next, I found an absolute gem of a quote to kick off the piece. It was from the eminently quotable Sydney Brenner.

Before we develop a pseudoscience of citation analysis, we should remind ourselves that what matters absolutely is the scientific content of a paper and that nothing will substitute for either knowing it…

The McGurk Effect – Do you always hear what you think you hear?

Posted in Biographical, The Universe and Stuff with tags , , , , on May 19, 2016 by telescoper

I saw this clip for the first time yesterday during a training session about unconscious bias. The context then was a discussion of how we make quick decisions about things (and people) relying on contextual associations of which we are often entirely unaware. The clip illustrates how difficult it is to overrule some things your brain does automatically even when you know they are wrong.

Related to this is something I’ve noticed in a slightly different setting. Not having a TV set I do sometimes watch DVDs on my laptop, but the screen is quite small and, for a person of my advanced years, rather difficult to view comfortably for a long period. A while ago I started plugging my laptop into a monitor instead. When I do that I usually put the laptop well out of the way, which means moving the relatively small loudspeaker out of the line of sight between myself and the screen. It is however immediately noticeable that the sound immediately seems to be coming from the screen rather than the speaker. I guess this is yet another example of the visual overruling the auditory which it does in the McGurk effect.

Oh, and I just remembered this, which I heard a while ago at a public talk given by Simon Singh. I guess many of you will have come across it before, but there’s no harm in repeating it. I don’t know why it popped into my head at this particular moment, but perhaps it’s because I’ve been reading some stuff about how my colleagues in gravitational wave research use templates to try to detect specific patterns in noisy data. The method involves cross-correlating a simulated signal against the data until a match is obtained; the problem is often how to assess the probability of a “chance” coincidence correctly and thus avoid spurious detections. The following might perhaps be a useful warning that unless you do this carefully, you only get out what you put in!

This is an excerpt from the classic track Stairway to Heaven, by the popular beat combo Led Zeppelin, played backwards. I suggest that you listen to it once without looking at the words on the video, and then again with the words in front of you. If you haven’t heard/seen it before, I think you’ll find it surprising…

 

The Moon is Distant from the Sea

Posted in Poetry, Uncategorized with tags , , on May 19, 2016 by telescoper

The moon is distant from the sea,
And yet with amber hands
She leads him, docile as a boy,
Along appointed sands.

He never misses a degree;
Obedient to her eye,
He comes just so far toward the town,
Just so far goes away.

Oh, Signor, thine the amber hand,
And mine the distant sea, —
Obedient to the least command
Thine eyes impose on me.

by Emily Dickinson (1830-1886)

 

Sinister Moves by Elsevier

Posted in Open Access with tags , , , , on May 18, 2016 by telescoper

I’ve been away at yet another Awayday today so only have time for a brief post before I go home and vegetate. I felt obliged, however, to draw the attention of my readership to the fact that there’s something sinister afoot in the world of academic publishing. It seems that the notoriously exploitative academic publishing company Elsevier has acquired the Social Science Research Network (SSRN), which is  the leading social science and humanities repository and online community. The SSRN currently allows readers free access more than 500,000 academic papers for free but that is highly likely to change under Elsevier whose previous practice has always been to squeeze the academic community for every penny it can get. In particular, Elsevier has a reputation for cracking down on academic papers for which it owns licences, so these recent acquisitions look like very bad news.

The Chairman of SSRN is  trying to present this as a positive move:

SSRN announced today that it has changed ownership. SSRN is joining Mendeley and Elsevier to coordinate our development and delivery of new products and services, and we look forward to our new access to data, products, and additional resources that this change facilitates.

Like SSRN, Mendeley and Elsevier are focused on creating tools that enhance researcher workflow and productivity. SSRN has been at the forefront of on-line sharing of working papers. We are committed to continue our innovation and this change will enable that to happen more quickly. SSRN will benefit from access to the vast new data and resources available, including Mendeley’s reference management and personal library management tools, their new researcher profile capabilities, and social networking features. Importantly, we will also have new access for SSRN members to authoritative performance measurement tools such as those powered by Scopus and Newsflo (a global media tracking tool). In addition, SSRN, Mendeley and Elsevier together can cooperatively build bridges to close the divide between the previously separate worlds and workflows of working papers and published papers.

We realize that this change may create some concerns about the intentions of a legacy publisher acquiring an open-access working paper repository. I shared this concern. But after much discussion about this matter and others in determining if Mendeley and Elsevier would be a good home for SSRN, I am convinced that they would be good stewards of our mission. And our copyright policies are not in conflict — our policy has always been to host only papers that do not infringe on copyrights. I expect we will have some conflicts as we align our interests, but I believe those will be surmountable.

Until recently I was convinced that the SSRN community was best served being a stand-alone entity. But in evaluating our future in the evolving landscape, I came to believe that SSRN would benefit from being more interconnected and with the resources available from a larger organization. For example, there is scale in systems administration and security, and SSRN can provide more value to users with access to more data and resources.

On a personal note, it has been an honor to be involved over the past 25 years in the founding and growth of the SSRN website and the incredible community of authors, researchers and institutions that has made this all possible. I consider it one of my great accomplishments in life. The community would not have been successful without the commitment of so many of you who have contributed in so many ways. I am proud of the community we have created, and I invite you to continue your involvement and support in this effort.

The staff at SSRN are all staying (including Gregg Gordon, CEO and myself), the Rochester office is still in place, it will still be free to upload and download papers, and we remain committed to “Tomorrow’s Research Today”. I look forward to and am committed to a successful transition and to another great 25 years for the SSRN community that rivals the first.

Michael C. Jensen
Founder & Chairman, SSRN

It sounds like they made him an offer he couldn’t refuse…

I don’t think Elsevier’s involvement in this is likely to prove beneficial to anything other than their own profits. Elsevier is one of the biggest problems in academic publishing and can  never be part of the solution.

My main concern, however,  is  that some day Elsevier might launch a hostile takeover bid for the arXiv, which would be a major setback to the physics community’s efforts to promote the free exchange of scientific papers. That must be resisted at all costs. How did the academic community allow its publishing culture to be hijacked by such companies?

 

 

 

 

It’s Mental Health Awareness Week

I will just add a comment of my own. No job is worth risking your mental health for. Nor is anything else for that matter.

The Thermal Syndicate

I found the above map of the Tyne via the Tyne & Wear Archives on Twitter. It dates from the 1960s, and it caught my attention because it shows the area where I was born, between Walker and Wallsend.

I remember  the Shipyards very well, especially the famous Neptune Yard of Swan Hunter. In the early 70s the huge ESSO Northumberland loomed above the terraced streets like a monster but now shipbuilding has all but vanished. So have most of the other industries lining the river, for that matter.

The other thing this map jogged my memory about was the Thermal Syndicate building. This was the site of a glassworks and the source of large quantities of silver sand, which my Dad used to buy and sell on to schools and playgroups as part of his educational supplies business, before it went under in the 1980s. The name always intrigued me as it made me imagine it was run by gangsters pushing winter underwear.

Listening and Seeing (and Mahler)

Posted in Biographical, Music with tags , , , , on May 14, 2016 by telescoper

Three things led me to post this recording. One is that this piece (though not this performance) was one of the late Harry Kroto’s selections for Desert Island Discs. Another is that I had occasion to sort out my CD collection recently and I realised in doing so that I had more recordings of this Symphony than any other. And the third is that I heard a discussion on Radio 3 recently in which a record company executive noted that while sales of opera performances on DVD were very healthy, it was very difficult to sell DVDs of symphonic concerts. I am not particularly surprised by that but I have to say that I love the visual as well as the auditory experience of a classical concert. A large group of talented people coming together to make music is a great thing to watch, and it also helps understand the music a bit too. I’d much rather go to a live concert (even a mediocre one) than listen to a CD (even a very good one), but failing that I’d definitely go for a DVD.

All of this provides an excuse to show this film of the Vienna Philharmonic under the baton of Leonard Bernstein playing the gorgeous third moment (marked Ruhevoll) of Symphony No. 4 in G Major by Gustav Mahler. My favourite recording of this symphony is actually by Von Karajan with the Berlin Philharmonic on Deutsche Grammophon, but this is well worth watching to see the communication between Lenny and the band. And if you think Mahler is always gloomy and angst-ridden, hopefully this will make you change your mind.

 

 

David MacKay’s Last Interview

Posted in The Universe and Stuff with tags , on May 13, 2016 by telescoper

I saw an interesting news item this morning reporting that at one point last Sunday about 87% of Germany’s energy needs were supplied by renewable sources. The circumstances that led to this were relatively short-lived, but it is interesting nevertheless. I keep an eye on the UK’s national grid statistics from time to time and it rarely exceeds 20% in the form of renewables.

Anyway, all that reminded me of this, which appeared in the Guardian a couple of weeks weeks ago. It’s the last interview recorded by David Mackay before his untimely death from cancer in April. He’s characteristically direct in pointing out that the idea that the UK could be powered entirely by renewable energy is not at all practicable.

 

 

The Supreme Leader of STFC Departs…

In case you haven’t heard yet, news has just broken that Professor John Womersley (above), currently Chief Executive of the Science & Technology Facilities Council (STFC), has been appointed Director-General of the new European Spallation Source (ESS) in Lund, Sweden, and will therefore be stepping down from his post as Chief Executive of STFC in the autumn.

John has been Supreme Leader at STFC for five years now and, in my opinion, has done an excellent job in circumstances that have not always been easy. He will be a hard act to follow. I know he’s an occasional reader of this blog, so let me take this opportunity to wish him well in his new role.

Now, perhaps I should open a book on the likely contenders for the post of next Chief Executive of STFC?
