“…As such, the present special section, entitled “Troubling Institutions at the Nexus of Care and Control,” can, we feel, be readily and usefully cast as a series of explorations – adopting an overtly institutional focus – tracking across the rough, tricky and lively grounds of care and control as surveyed by Puig de la Bellacasa. Cheryl McGeachan () writes in the title of her paper about “the enfolding spatialities of care and control,” Jennifer Turner and Dominique Moran () about “careful control,” Frank Ollivon () about an “ethics of care in a control‐orientated technology,” Virve Repo () about “spatial control and care,” and Emma Wainwright and Elodie Marandet () about “care and control.” While Puig de la Bellacasa's approach is not itself “a sociological or ethnographic inquiry into a specific domain of agencies of care,” her trajectory is one that “invites others to consider care – or its absence – as a parameter of existence with significance for their own terrains” (Puig de la Bellacasa, , p. 6). The authors contributing to the present special section are indeed contemplating such matters on “their own terrains,” offering valuable insights relevant to these local terrains – all of which are placed in named locations (e.g., the Barlinnie Special Unit, north‐east of Glasgow, Scotland) and specifiable categories of site (e.g., UK prisons, homes of electronically tagged French offenders, Finnish nursing homes; UK housing associations) – but also, as gathered together here, comprising resources for comparative interpretation (perhaps with reference to the more widely travelling speculations of Puig de la Bellacasa and others).…”
