### Another journal flips

July 27, 2017

There is widespread (even if not universal) agreement that something is deeply wrong with the current system of academic publishing. The basic point, which has been made innumerable times by innumerable people, is that the really hard parts — the writing of papers, and the peer review and selection of the ones to publish — are done voluntarily by academics, and modern technology makes things like typesetting and dissemination extremely cheap. And yet publishers are making more money than ever before. They do this by insisting that we give them ownership of the content we produce (though many journals will publish papers even if you strike out the part of the contract that hands them this ownership — these days I never agree to give copyright to a publisher, and I urge you not to either), and by bundling their journals together so that libraries are forced into an all-or-nothing decision. (As another aside, I also urge libraries to look closely at what is happening in Germany, where they have gone for the “nothing” option with Elsevier and the world has not come to an end.)

What can be done about this? There are many actions, none of which are likely to be sufficient to bring about major change on their own, but which in combination will help to get us to a tipping point. In no particular order, here are some of them.

1. Create new journals that operate much more cheaply and wait for them to become established.
2. Persuade libraries not to agree to Big Deals with the big publishers.
3. Refuse to publish with, write for, or edit for, the big publishers.
4. Make sure all your work is freely available online.
5. Encourage journals that are supporting the big publishers to leave those publishers and set up in a cheaper and fairer way.

Not all of these are easy things to do, but I’m delighted to report that a small group I belong to, set up by Mark Wilson, has, after approaching a large number of maths journals, found one that was ready to “flip”: the Journal of Algebraic Combinatorics has just announced that it will be leaving Springer. Or if you want to be more pedantic about it, a new journal will be starting, called Algebraic Combinatorics and published by The Mersenne Centre for Open Scientific Publishing, and almost all the editors of the Journal of Algebraic Combinatorics will resign from that journal and become editors of the new one, which will adhere to Fair Open Access Principles.

If you want to see change, then you should from now on regard Algebraic Combinatorics as the true continuation of the Journal of Algebraic Combinatorics, and the Journal of Algebraic Combinatorics as a zombie journal that happens to have a name that coincides with a former real journal. And of course, that means that if you are an algebraic combinatorialist with a paper that would have been suitable for the Journal of Algebraic Combinatorics, you should understand that the reputation of the Journal of Algebraic Combinatorics is being transferred, along with the editorial board, to Algebraic Combinatorics, and you should therefore submit it to Algebraic Combinatorics. This has worked with previous flips: the zombie journal rarely thrives afterwards and in some notable cases has ceased to publish after a couple of years or so.

### Intransitive dice VI: sketch proof of the main conjecture for the balanced-sequences model

July 25, 2017

I have now completed a draft of a write-up of a proof of the following statement. Recall that a random $n$-sided die (in the balanced-sequences model) is a sequence of length $n$ of integers between 1 and $n$ that add up to $n(n+1)/2$, chosen uniformly from all such sequences. A die $(a_1,\dots,a_n)$ beats a die $(b_1,\dots,b_n)$ if the number of pairs $(i,j)$ such that $a_i>b_j$ exceeds the number of pairs $(i,j)$ such that $a_i. If the two numbers are the same, we say that $A$ ties with $B$.

Theorem. Let $A,B$ and $C$ be random $n$-sided dice. Then the probability that $A$ beats $C$ given that $A$ beats $B$ and $B$ beats $C$ is $\frac 12+o(1)$.

In this post I want to give a fairly detailed sketch of the proof, which will I hope make it clearer what is going on in the write-up.
