I am fairly amazed that Neil Baxter, representing RIAS, does not see the complete lack of women speakers at their conference as a problem. It was the very first thing that struck me when I saw the brochure. We live in a world where women design, commission and use buildings, just the same as men and to not show any recognition of this seems ill considered. If RIAS would like some assistance in finding women to speak at their conference they could try reading this: http://feministphilosophers.wordpress.com/2011/03/26/how-to-avoid-a-gendered-conference/.
It doesn't reflect our society to simply say none were available.
