Antarctic sabbatical

Airbnb is supporting 5 volunteers that wish to join next December environmental scientist Kirstie Jones-Williams, from the University of Exeter, on a scientific expedition in Antarctica, investigating the presence of microplastics there. The deadline for applications  is 11:59pm EDT on 8 October 2019. (I wish I could, but the news came a bit late to contemplate rescheduling a large number of classes.) As the offer includes riding snowmobiles and fat tyre bikes, and visiting sites over Antarctica, during the one week stay there, this obviously sounds more like covert tourism than a genuine expedition. With a dose of greenwashing by Airbnb, “inherently more eco-friendly than other forms of travel given that people are using spaces already built” to quote from the University of Exeter webpage, which does not mention the impact of airbnbing locals out of city centres by drying out long-term rentals and raising housing prices sky-high… (As a long-term user of airbnb, hence accomplice to the fact, I noticed a rising proportion of places that are sheer around-the-year rentals rather than occasionally let to visitors. And hope the alternative platform fairbnb.coop will launch soon.)

CNRS bans airbnb!

A few days ago, like all members of French research labs associated with CNRS, the national research institute, I received an email stating

” Le recours aux service de co-voiturage (ex, BlablaCar) et le recours aux services de location entre particuliers (ex. Air B&B [sic]) ne sont pas autorisés car ils font peser un risque sur le CNRS en termes de responsabilité.”

which means that it will no longer reimburse travel expenses connected to airbnb rentals for fear of litigation. While the decision is not completely surprising, given the bureaucratic tendencies of the CNRS, and the fact that cities and administrations are increasingly targeting airbnb, making it primarily a politically motivated ban, this is a most unwelcome item of news, both for funding reasons, as airbnb or a similar rental service offers massive gains when attending a conference with colleagues, and for comfort reasons, as I find resorting to hotels much less relaxing than in a rental, if only because I cannot cook and eat what I want.

conference deadlines

Just to remind participants to AISTATS 2016 and to ISBA 2016 that the deadlines for early registration are January 31 and February 10, getting close. Since both fees are quite high, it certainly makes sense to take advantage of those deadlines (and to make all travel reservations). (While I did try to see the fees of AISTATS 2016 set to a lower value, half of the fees are paying for coffee breaks and the banquet and the welcome party and were not negotiable. As my suggestion of cancelling the banquet was not accepted either! At least, the offer of accommodations in Cadiz is reasonable, from the list of hotels on the website, to a large collection of airbnb listings [minus the one I just reserved!]. And both Spain and Italy set an heavy 20% tax on conferences… Warning: the AISTATS 2016 do not cover the shuttle bus transfer from Sevilla, the major airport in the vicinity.)

MCMskv #5 [future with a view]

As I am flying back to Paris (with an afternoon committee meeting in München in-between), I am reminiscing on the superlative scientific quality of this MCMski meeting, on the novel directions in computational Bayesian statistics exhibited therein, and on the potential settings for the next meeting. If any.

First, as hopefully obvious from my previous entries, I found the scientific program very exciting, with almost uniformly terrific talks, and a coverage of the field of computational Bayesian statistics that is perfectly tuned to my own interest. In that sense, MCMski is my “top one” conference! Even without considering the idyllic location. While some of the talks were about papers I had already read (and commented here), others brought new vistas and ideas. If one theme is to emerge from this meeting it has to be the one of approximate and noisy algorithms, with a wide variety of solutions and approaches to overcome complexity issues. If anything, I wish the solutions would also incorporate the Boxian fact that the statistical models themselves are approximate. Overall, a fantastic program (says one member of the scientific committee).

Second, as with previous MCMski meetings, I again enjoyed the unique ambience of the meeting, which always feels more relaxed and friendly than other conferences of a similar size, maybe because of the après-ski atmosphere or of the special coziness provided by luxurious mountain hotels. This year hotel was particularly pleasant, with non-guests like myself able to partake of some of their facilities. A big thank you to Anto for arranging so meticulously all the details of such a large meeting!!! I am even more grateful when realising this is the third time Anto takes over the heavy load of organising MCMski. Grazie mille!

Since this is a [and even the!] BayesComp conference, the current section program chair and board must decide on the  structure and schedule of the next meeting. A few suggestions if I may: I would scrap entirely the name MCMski from the next conference as (a) it may sound like academic tourism for unaware bystanders (who only need to check the program of any of the MCMski conferences to stand reassured!) and (b) its topic go way beyond MCMC. Given the large attendance and equally large proportion of young researchers, I would also advise against hosting the conference in a ski resort for both cost and accessibility reasons [as we had already discussed after MCMskiv], in favour of a large enough town to offer a reasonable range of accommodations and of travel options. Like Chamonix, Innsbruck, Reykjavik, or any place with a major airport about one hour away… If nothing is available with skiing possibilities, so be it! While the outdoor inclinations of the early organisers induced us to pick locations where skiing over lunch break was a perk, any accessible location that allows for a concentration of researchers in a small area and for the ensuing day-long exchange is fine! Among the novelties in the program, the tutorials and the Breaking news! sessions were quite successful (says one member of the scientific committee). And should be continued in one format or another. Maybe a more programming thread could be added as well… And as we had mentioned earlier, to see a stronger involvement of the Young Bayesian section in the program would be great! (Even though the current meeting already had many young researcher  talks.)
