All life-events are significant!
Prof. Ian Ruthwen (University of Strathclyde) held an interesting keynote at 2016 edition of the ISIC - Information Behaviour Conference in Zadar, Croatia. He talked about information behaviours (sic!) related to significant life events and made broadly remarks on what is significant in significant life events and how these aspects have possible repercussions on how people deal with information.
At the same time, his remarks could be seen as thought-provoking on how people work with information on not-so-significant-life-events and how a significance of a life-event actually can be question of different shades of grey rather than a binary condition. To a certain extent you could probably argue that any event that trigger explicit information interactions is a significant life-event with similar mechanisms (even if they would play out to a considerably less dramatic degree) that are pertinent to such stereotypic significant life-events as serious illness, death of a relative, marriage, change of job, or something similar.
Conference featured also several other interesting papers and posters (abstract can be found on the ISIC conference website), and the session with the participants of the doctoral forum gave a lot of promise of the future of the information behaviour research (including information practices related and other research focussing on how people deal with information independent of how individual researchers have chosen to call it). My own paper discussed distrust, mistrust and untrust as related but independent states of (non-)trust that should be taken into account when discussing trust in the context of information research. The HIBA project was presented in poster form, and I had also an opportunity (that your for organisers) to participate in an interesting and important panel on the present and future of ISIC conference and community.
