This and that

1. July 2011

Kid is growing, lack of sleep makes euphoric, but less time is less time;-)

The 2010 impact factors were just released by Thomson Reuters, Sunset at Ammerseeas most of you will know due to the mails sent by almost all publishers to tell about recent boosts of impact for their journals. A sober post was written by Jörg Heber, editor of Nature materials. A brief quote

So what use is the impact factor number? Well, being cynical one could say it is a quick measure for those that don’t read the journals but still want to know how good they are on average. The danger is of course that this is then used as a kind of metric to assess the quality of research or to decide on the career of researchers.

Publish like a pro

14. October 2010

Today, I saw the article Publish like a pro by Kendall Powell in Nature. Some tips on how to write:

  • You are only as good as your last paper – previous success does not guarantee future acceptance.Walking to Schloss Burg
  • You’ve got to hook the editor with the abstract.
  • Don’t delete those files. Keep every version. You never know what aspect you can use for some other piece of writing.
  • Writing is an amazingly long learning curve. many authors say that they’re still getting better as a writer after several decades.
  • The most significant work is improved by subtraction. Keeping the clutter away allows a central message to be communicated with a broader impact.
  • Write every day if possible.
  • once you’ve written what you wanted to convey, end it there.

These go hand in hand with this earlier post, although Kendall’s article does not stop there. Therefore, read it!

Personally, what I need for writing is a quiet, non-distracting environment with the internet switched off.

MRS Spring Meeting 2010… already over

12. April 2010

Last week, the MRS Spring Meeting took place in San Francisco. It was my first time there, but certainly not the last! ruffled feathersI enjoyed it immensely, despite my extensive last minute preparations of the talk I was invited to give… another first timer for me (on an international conference). In case you are interested, find the slides on scribd. Prof. Venkateswara Bommisetty, one of the organisers of the GG symposium told me that the slides of invited talks will also be made available (if the authors agree).

Many interesting talks, too many to go into more detail in the given time!;-) Anyway, it was nice to meet Alex (glidera) and his colleague Bertrand in person, and spend time with Andy B and Tom!

It was difficult (if not impossible) to agree with Alan Heeger and Robert Street on their propositions that monomolecular recombination is the limiting factor for organic bulk heterojunction solar cells at short circuit current under one sun illumination. Thus, despite both of them being well-known and highly respected, I allow myself to express my strong belief (supported by transient experiments and macroscopic simulations;-) that bimolecular polaron recombination is the dominant loss mechanism for free polarons, instead of monomolecular polaron recombination. Maybe more on this later.

During the conference, and featured in the talk of Karl Leo, Heliatek announced another efficiency record for small molecule solar cells, enhancing their recent achievements to now 7.7% certified efficiency for a tandem cell with 1.1cm2. Again, my congratulations, great stuff!

Publications – Wind of change?

24. February 2010

Via Die Zeit and Nature:
The DFG, Germany’s main funding agency, just put down new guidelines for proposals. Starting in July, the proposals should contain only two directly relevant publications per year of requested funding, as well as up to five other papers (presumably the most important ones) covering the researcher’s general background. Matthias Kleiner, DFG president:

It is quality, not quantity, which matters.

Good point. Nevertheless, although the publish and perish mentality lately became quite tiring, I wonder if (how quickly) these new conditions will change the mentality of the researchers in general, and in particular the ones who are reviewing the proposals and are sitting in the committees for professorship appointment;-)

[Update 25.2.2010] Find the original DFG statement here (pdf, german).

How to publish… not so seriously

24. September 2009

Great comical contribution of Jorge Cham’s PhD Comics: ButterflyNature vs Science

The Nature Journal liked it, as apparent from their blog post ;-) According to Jorge Cham, their general comment was:

Use this comic for procrastination or decompression, as you see fit.

How to publish… seriously

1. September 2009

Less sad than the recent Note on publishing a scientific commentGolden GateAs I am in a constant process of trying to understand the requirements for publishing high-impact scientific papers better (slow process… ;-) , I am always eager to see what others write about it.

Recently, I linked to some PLOS editorials about Ten simple rules for nearly everything, including writing papers.

Along this line, the presentation given by the Phys. Rev. Lett. Editor Manolis Antonoyiannakis in Japan end of last year, is very interesting. In addition to hints for using the right phrasing when writing about scientific results, he also gives some insight – from the viewpoint of the Editorial Office of a high impact phyics journal – into the inner workings of paper predecision (by Editor) and general acceptance rate.

How to Publish a Scientific Comment…

20. August 2009

Via the blog Dynamics of Cats: How to publish a scientific comment in 123 Easy Steps by Prof. Rick Trebino. I do not have first hand experience myself, but the described exchange between commentator and editor is very interesting, and indeed very disturbing for an open-minded scientist! See also a comment on Trebino’s essay in the blog Adventures in Ethics and Science.

Ten Simple Rules…

7. July 2009

Already a couple of years ago, the editorial of PLoS Computational Biology was about Ten Simple Rules on Getting Published, Royal Gardenswhich contained useful advice for young scientists. As it was quite successfull in terms of positive response and also the number of downloads, its author Prof. P. E. Bourne wrote advice concerning other non-science but science-related topics for young scientists on PhD and PostDoc level, such as Ten Simple Rules for Getting Grants, Ten Simple Rules for Making Good Oral Presentations, and more. I always liked the idea, and as I recently stumbled across one of these articles, I share the links here. These editorials are open access.

Science 3.0?

1. May 2009

Via Academic Productivity: Interesting comment, What can Science learn from Google? I especially like that it starts with a quote by George Box (you know I like them ;-)

All models are wrong, but some are useful.

Wide OpenThe article takes the provocative stance that we do not need models any more to describe the world, as petabyte data clouds combined with massive computing power are able to correlate data.

Data without a model is just noise. But faced with massive data, this approach to science — hypothesize, model, test — is becoming obsolete. [...] Correlation supersedes causation, and science can advance even without coherent models, unified theories, or really any mechanistic explanation at all.

I humbly disagree. Understanding needs models, predictions need models. Of course, in order to find models, correlations – probably found by using computers – can show the way.

It is not only content that counts…

5. November 2008

rhetoric also counts in publishing papers: see this blog entry by Jose Quesada from Academic Productivity, “Writing style” vs. “content”: Watson & Crick’s example.
