摘要：The drive for impact from research projects presents a dilemma for science communication researchers and practitioners — should public engagement be regarded only as a mechanism for providing evidence of the impact of research or as itself a form of impact? This editorial describes the curation of five commentaries resulting from the recent international conference ‘Science in Public: Research, Practice, Impact’. The commentaries reveal the issues science communicators may face in implementing public engagement with science that has an impact; from planning and co-producing projects with impact in mind, to organising and operating activities which meet the needs of our publics, and finally measuring and evaluating the effects on scientists and publics in order to ‘capture impact’.
