The conference provides a forum for discussion on developments and applications of Bayesian statistics, and includes keynote presentations, tutorials, practical problem-based workshops, invited oral presentations, and poster presentations.

Several interesting entries in Le Monde Science & Médecine of this week (24 Jan 2018):

  1. This incredible report in the Journal of Ethnobiology of fire-spreading raptors, Black Kite, Whistling Kite, and Brown Falcon, who carry burning material to start fires further away and thus expose rodents and insects. This behaviour was already reported in some Aboriginal myths, as now backed up by independent observations.
  2. A report by Etienne Ghys of the opening of a new CNRS unit in mathematics in… London! The Abraham de Moivre Laboratory is one of the 36 mixed units located outside France to facilitate exchanges and collaborations. In the current case, in collaboration with Imperial. And as a mild antidote to Brexit and its consequences on exchanges between the UK and the EU. (When discussing Martin Hairer’s conference, Etienne forgot to mention his previous affiliation with Warwick.)
  3. A good-will-bad-stats article on the impact of increasing the number of urban bicycle trips to reduce the number of deaths. With the estimation that if 25% of the daily trips over 167 European (and British!) cities were done by bike, 10,000 deaths per year could be avoided! I have not read the original study, but I wonder at the true impact of this increase. If 25% of the commutes are made by bike, the remaining 75% are not and hence use polluting means of transportation. This means more citizens travelling by bike are exposed to the exhausts and fumes of cars, buses, trucks, &tc. Which should see an increase in respiratory diseases, including deaths, rather than a decrease. Unless this measure is associated with banning all exhaust emissions from cities, which does not sound a very likely outcome, even in Paris.
  4. An incoming happening at Cité internationale des Arts in Paris, on Feb 2-3, entitled “we are not the number we believe we are” (in French), based on the universe(s) of Ursula Le Guin who most sadly passed away the day the journal came out.
  5. A diffusion of urban riots in the suburbs of Paris in 2005 that closely follows epidemiological models of flu epidemics, using “a single sociological variable characterizing neighbourhood deprivation”. (Estimation of the SIR model is apparently done by maximum likelihood and model comparison by AIC, given the ODE nature of the models, ABC would have been quite appropriate for a Bayesian modelling!)

Bayes on the beach [and no bogus!]

Bayes on the Beach is a yearly conference taking place in Queensland Gold Coast and organised by Kerrie Mengersen and her BRAG research group at QUT. To quote from the email I just received, the conference will be held at the Mantra Legends Hotel on Surfers Paradise, Gold Coast during November 7 – 9, 2016. The conference provides a forum for discussion on developments and applications of Bayesian statistics, and includes keynote presentations, tutorials, practical problem-based workshops, invited oral presentations, and poster presentations. Abstract submissions are now open until September 2.

AMSI Lectures #8-10

Posted in Statistics, Travel with tags , , , , , , , , , on August 21, 2012 by xi'an

This is the last series of lectures for my AMSI Lecture tour: in Brisbane, I gave the Rao-Blackwellisation talk this afternoon at the University of Queensland and will give tomorrow both the public lecture (for the second time) and the ABC for model choice at QUT. This will then see the end to this (almost) exhaustive if exhausting tour of Eastern Australian university towns… Brisbane has this great feature of connecting QUT with UQ by a fast boat, which meant I could work with Kerrie Mengersen on the revision of our ABCel paper in the morning and be at UQ ½ an hour later. A good thing as there are only three days left till I leave Australia after this seven week visit… (I am afraid there is no free time left for sampling the Brisbane dumplings!)
