I post the announcement of this conference as they specifically invite submissions in the philosophy of science.
The British Society for History of Science is organizing a postgraduate (meaning MA and PhD students) conference in Leeds, 8-10 January 2014. The deadline is 8th November, and they encourage papers in philosophy of science. The website with relevant info is here: http://www.bshs.org.uk/conferences/postgraduate-conference/2014-postgraduate-conference-leeds. Also, travel grants from BSHS are available.
