<p>Waking up to the reactivity of concepts to their myriad possibilities for signification to the range and strength of affective responses they provoke can happen at any time in any place. Conceptual contestations shake up the comfortably consolidated foundations of sociological knowledge production but they also have consequences for the ways in which lives are understood researched and legislated for. This book is dedicated to exploring the definitional politics which surround the concept of gender in ‘live’ knowledge production. While conferences remain an under-researched phenomenon this volume places conference knowledge production under the spotlight; conferences in particular national women’s studies association conferences in the UK the US and India are explored as sites where definitional politics play out. The cumulative theorisation of ‘live’ conceptual knowledge production that is developed throughout the book draws on established constructs such as performativity citationality intersectionality materiality and events but works with them in combination in a new unique way. The book as a whole calls for more attention to be paid to conceptual knowledge production so as to make more space for potentially transformative conceptual change. </p><p></p>
