Derivation of constraints and database relations
, 1996 In this paper we investigate which constraints may be derived from a given set of constraints. We show that, given a set of relations R, all of which are invariant under some set of permutations P, it is possible to derive any other relation which is invariant under P, using only the projection, Cartesian product, and selection operators, together with

Educational pathways and outcomes for care‐experienced children: A 16‐year longitudinal study
British Educational Research Journal, EarlyView.Abstract Children who are removed from their birth families during childhood—termed care‐experienced—can be at risk for lower educational attainment and poorer school experiences, often linked to deprivation and behavioural factors. However, research often uses aggregated measures that obscure the complexities of care (e.g.

Relational Databases and Bell’s Theorem [PDF]
, 2013 Our aim in this paper is to point out a surprising formal connection, between two topics which seem on face value to have nothing to do with each other: relational database theory, and the study of non-locality and contextuality in the foundations of quantum mechanics.
