hematicians at leicester redundant the story is spreading rapidly on social media it s attracted quite a bit of attention on twitter reddit and hacker news for example so i won t write a long post but just in case you haven t heard about it here s a link to a petition you can sign if like a lot of other people you feel strongly that this is a bad decision at the time of writing it has been signed by about 2 500 people many of them very well known academics in the areas that leicester university claims to be intending to promote in well under 24 hours posted in uncategorized 14 comments mathematical research reports a new mathematics journal is launched may 20 2020 from time to time academic journals undergo an interesting process of fission typically as a result of some serious dissatisfaction the editorial board resigns en masse to set up a new journal the publishers of the original journal build a new editorial board from scratch and the result is two journals one inheriting the editors and collective memory of the original journal and the other keeping the name and the publisher which is the true successor in practice it tends to be the one with the editors with its sibling surviving as a zombie journal that is the successor in name only perhaps there are examples that go the other way and there may be examples where both journals go on to thrive but i have not looked closely at the examples i know about i m mentioning this because recently i have been involved in a rather unusual example of this phenomenon most cases i know of are the result either of frustration with the practices of the big commercial publishers or of malpractice by an editor in chief but this was an open access journal with no publication charges and with an extremely efficient and impeccably behaved editor in chief so what was the problem the journal started out in 1995 as electronic research announcements of the ams or era ams for short it was still called that when i first joined the editorial board its editor in chief was svetlana katok who did a great job and there was a high powered editorial board as its name suggests it specialized in shortish papers announcing results that would then appear with more details in significantly longer papers so it was a little like comptes rendus in its aim it would also accept short articles of a more traditional kind it never published all that many papers and in 2007 i think for that reason but don t remember for sure the ams decided to discontinue it but svetlana katok had put a lot into the journal and managed to find another publisher the american institute of mathematical sciences and the editorial board agreed to continue serving the name of the journal was changed to electronic research announcements in the mathematical sciences and its abbreviation was slightly abbreviated from era ams to era ms in 2016 after 22 years svetlana katok decided to step down and boris hasselblatt took over it was a good moment to try to revitalize the journal so measures were taken such as designing a new and better website and making more effort to publicize the journal in the hope of attracting more submissions or more precisely more submissions of a high enough quality that we would want to publish them however despite these measures the numbers remained fairly low around ten a year with quite a bit of variation and this indirectly caused the problem that led to the split the editors would have liked to see more papers published but were not worried about it to the point where we would have been prepared to sacrifice quality to achieve it we were ready to accept that this was at least for now a small journal but aims was not so happy in an effort to remedy as they saw it the situation they appointed a co editor in chief who in turn appointed a number of new editors with a more applied focus with the idea that by broadening the scope of the journal they would increase the number of papers published that did not precipitate the resignations but at that stage most of us did not know that the new editors had been appointed without any consultation even with boris hasselblatt but then aims took things a step further until that point the journal had adopted a practice that i strongly approve of which was for the editor who handled a paper to make a recommendation to the rest of the editorial board with other editors encouraged to comment on that recommendation this practice helps to guard against rogue editors and against abuse of the system in general it also helps to maintain consistent standards and provides a gentle pressure on editors to do their job conscientiously there s nothing like knowing that you re going to have to justify your decision to a bunch of mathematicians but suddenly the publishers told us that this system had to change and that from now on the editorial board would not have the opportunity to vet papers and would continue to have no say in new editorial appointments various justifications were given for this including that it would make it harder to recruit editors if they thought they had to make judgments about papers not in their immediate area at that point it was clear that the soul of the journal was about to be destroyed so over a few days the entire board from before the start of the changes resigned resolving to start afresh with a new name that new name is mathematical research reports we will continue to accept reports on longer work as well as short articles in addition we welcome short survey articles we regard it as the continuation in spirit of era ms another unusual feature of this particular split is that the other half still published by aims has also changed its name and is now called electronic research archive if like me you are always on the lookout for high quality ethical journals which i loosely define as free to read free to publish in and adopting high standards of editorial practice then please add mathematical research reports to your list have a look at the back catalogue of era ms and era ams and you will get an idea of our standards it would be wonderful if the unfortunate events of the last year or so were to be the catalyst that led to the journal finally becoming established in the way that it has deserved to be for a long time posted in news 12 comments how long should a lockdown relaxation cycle last march 28 2020 the adaptive triggering policy on page 12 of a document put out by imperial college london which has been very widely read and commented on and which has had a significant influence on uk policy concerning the coronavirus there is a diagram that shows the possible impact of a strategy of alternating between measures that are serious enough to cause the number of cases to decline and more relaxed measures that allow it to grow again they call this adaptive triggering when the number of cases needing intensive care reaches a certain level per week the stronger measures are triggered and when it declines to some other level the numbers they give are 100 and 50 respectively they are lifted if such a policy were ever to be enacted a very important question would be how to optimize the choice of the two triggers i ve tried to work this out subject to certain simplifying assumptions and it s important to stress right at the outset that these assumptions are questionable and therefore that any conclusion i come to should be treated with great caution this post is to show the calculation i did it leads to slightly counterintuitive results so part of my reason for posting it publicly is as a sanity check i know that if i post it here then any flaws in my reasoning will be quickly picked up and the contrapositive of that statement is that if the reasoning survives the harsh scrutiny of a typical reader of this blog then i can feel fairly confident about it of course it may also be that i have failed to model some aspect of the situation that would make a material difference to the conclusions i draw i would be very interested in criticisms of that kind too indeed i make some myself in the post before i get on to what the model is i would like to make clear that i am not advocating this adaptive triggering policy personally what i would like to see is something more like what tomas pueyo calls the hammer and the dance roughly speaking you get the cases down to a trickle and then you stop that trickle turning back into a flood by stamping down hard on local outbreaks using a lot of testing contact tracing isolation of potential infected people etc this would need to be combined with other measures such as quarantine for people arriving from more affected countries etc but it still seems worth thinking about the adaptive triggering policy in case the hammer and dance policy doesn t work which could be for the simple reason that a government decides not to implement it read

combinatorics a new arxiv overlay journal that is run along similar lines to discrete analysis has just published its first five articles with plenty more in the pipeline i am excited by the business model of the journal which is that its very small running costs like discrete analysis it uses the scholastica platform which charges 10 per submission as well as a fixed annual charge of 250 and there are a few other costs such as archiving articles with clockss and having dois are being met for the next five years in the first instance by the library of queens university in kingston ontario who are also providing us with very useful administrative support my dream would be for other libraries to have the foresight to support similar ventures since the potential for savings if the stranglehold of the big commercial publishers is broken is huge i do not underestimate the obstacles but for a long time i have felt that what we are waiting for is a tipping point and even quite a small venture can in principle have a significant effect on when that tipping point occurs the aim of advances in combinatorics is to be a top specialist combinatorics journal information about the editorial board the submission process and of course the articles themselves can all be found on the website like discrete analysis the journal has editorial introductions to each article with the aim of making the webpage informative and fun to browse we will be grateful for any feedback and even more grateful for support in the form of excellent combinatorics papers while we are still getting established a final remark is that although i have reached the limit of the number of journals of this type that i can be closely involved in i would be delighted to hear from anybody who thinks that they can put together a high quality editorial board in an area that does not have a suitable journal for people who want to publish good papers without supporting the big commercial publishers i know people who can offer advice about suitable platforms funding and similar matters it would be great if free to read free to publish journals could cover all of mathematics but we are still a long way from that at the moment posted in news 15 comments the fate of combinatorics at strathclyde june 19 2019 i have just received an email from sergey kitaev one of the three combinatorialists at strathclyde as in many universities they belong not to the mathematics department but to the computer science department kitaev informs me that the administrators of that department in their infinite wisdom have decided that the future of the department is best served by axing discrete mathematics i won t write a long post about this but instead refer you to a post by peter cameron that says everything i would want to say about the decision and does so extremely cogently i recommend that you read it if this kind of decision worries you posted in news 7 comments voting tactically in the eu elections may 21 2019 this post is addressed at anyone who is voting in great britain in the forthcoming elections to the european parliament and whose principal aim is to maximize the number of meps from remain supporting parties where those are deemed to be the liberal democrats the greens change uk plaid cymru and the scottish national party if you have other priorities then the general principles laid out here may be helpful but the examples of how to apply them will not necessarily be appropriate to your particular concerns what is the voting system the system used is called the d hondt system the country is divided into a number of regions and from each region several meps will be elected you get one vote and it is for a party rather than a single candidate once the votes are in there are a couple of ways of thinking about how they translate into results one that i like is to imagine that the parties have the option of assigning their votes to their candidates as they wish and once the assignments have been made the candidates with the most votes get seats where is the number of meps representing the given region for example if there are three parties for four places and their vote shares are 50 30 and 20 then the first party will give 25 to two candidates and both will be elected if the second party tries a similar trick it will only get one candidate through because the 20 that goes to the third party is greater than the 15 going to the two candidates from the second party so the result is two candidates for the first party one for the second and one for the third if the vote shares had been 60 25 and 15 then the first party could afford to split three ways and the result would be three seats for the first party and one for the second read the rest of

taught maths by craig barton that seemed to be highly thought of the basic idea was that craig barton is an experienced and by the sound of things very good maths teacher who used to take a number of aspects of teaching for granted until he looked into the mathematics education literature and came to realize that many of his cherished beliefs were completely wrong since i ve always been interested in the question of how best to teach mathematics both because of my own university teaching and because from time to time i like to pontificate about school level teaching i decided to order the book more surprisingly given my past history of buying books that i felt i ought to read i read it from cover to cover all 450 pages of it as it happens the book is ideally designed for people who don t necessarily want to read it from cover to cover because it is arranged as follows at the top level it is divided into chapters each chapter star...
