Opening Up Ownership: Community Belonging, Belongings and the Productive Life of Property

Drawing on empirical data and property theory, this paper explores the property structure of a free school and the work property performs there. Its organising principle is a tension between two school practices. On the one hand, the founder and present members stress the importance of individual ownership; at the same time the school’s property regime involves property-limitation rules, a dispersal of rights, collective forms of property, and cross-cutting, pluralized sites of institutional recognition. In exploring how this tension is manifested through property’s work, the paper focuses on property’s contribution to a variegated social, at the school, analysed in terms of personal, civic and boundary relations. With belonging treated as the central component of property, rather than exclusion or control, ways of understanding how property works shift. In particular, the paper revisits claims regarding property’s constitutive or formative power

Cognitive deficit and white matter changes in persons with celiac disease: a population-based study

Background & Aims There is debate over the presence and prevalence of brain injury in patients with celiac disease. To validate previous reports, we investigated the prevalence of neuropsychological dysfunction in persons with celiac disease included in the National UK Biobank, which contains experimental medical data from 500,000 adults in the United Kingdom. Methods Biobank participants with celiac disease (n=104; mean age, 63; 65% female) were matched with healthy individuals (controls, n=198; mean age, 63 y; 67% female) for age, sex, level of education, body mass index, and diagnosis of hypertension. All subjects were otherwise healthy. We compared scores from 5 cognitive tests, and multiple-choice responses to 6 questions about mental health, between groups using t test and χ2 analyses. Groupwise analyses of magnetic resonance imaging brain data included a study of diffusion tensor imaging metrics (mean diffusivity, fractional anisotropy, radial diffusivity, axial diffusivity), voxel-based morphometry, and Mann-Whitney U comparisons of Fazekas grades. Results Compared with controls, participants with celiac disease had significant deficits in reaction time (P=.004) and significantly higher proportions had indications of anxiety (P=.025), depression (P=.015), thoughts of self-harm (P=.025) and health-related unhappiness (P=.010). Tract-based spatial statistics analysis revealed significantly increased axial diffusivity in widespread locations, demonstrating white matter changes in brains of participants with celiac disease. Voxel-based morphometry and Fazekas grade analyses did not differ significantly between groups. Conclusions In an analysis of data from the UK Biobank, we found participants with celiac disease to have cognitive deficit, indications of worsened mental health, and white matter changes, based on analyses of brain images. These findings support the concept that celiac disease is associated with neurological and psychological features
