A multi-disciplinary and comparative approach to evaluating pre-trial detention decisions: towards evidence-based reform

The decision to remand a defendant into custody pre-trial is one of the most controversial criminal justice decisions because it deprives individuals of their liberty while they are presumed to be innocent of a crime. Indeed, pre-trial detention decisions can have significant consequences for defendants, which need to be balanced against the potential implications of bail for public safety and the course of criminal proceedings. Despite this, court-based bail and remand decision-making remains relatively underexplored. In this paper, we compare court-based bail/remand decision-making in England and Wales and The Netherlands. We focus on (i) the procedure and structure of decision-making; (ii) the substantive relevant legal frameworks; (iii) the courts in which the decisions are made and the decision-makers in those courts; (iv) the conditions characterizing the decision task; and (v) the court’s reasoning of bail and remand in custody decisions. Using a comparative and multi-disciplinary approach, relying on Law, Criminology and Psychology, we make predictions about bail and remand in custody rates in the two jurisdictions as well as the decision performance of court-based decision-makers. These predictions are then evaluated using available (official) statistics and past research. We identify the need to collect more nuanced statistical data on bail and remand in custody rates and point to potentially fruitful avenues for future research. A comparative, multi-disciplinary, evidence-based approach can underpin remand reform in England and Wales, The Netherlands and beyond

KCrF_3: Electronic Structure, Magnetic and Orbital Ordering from First Principles

The electronic, magnetic and orbital structures of KCrF_3 are determined in all its recently identified crystallographic phases (cubic, tetragonal, and monoclinic) with a set of {\it ab initio} LSDA and LSDA+U calculations. The high-temperature undistorted cubic phase is metallic within the LSDA, but at the LSDA+U level it is a Mott insulator with a gap of 1.72 eV. The tetragonal and monoclinic phases of KCrF_3 exhibit cooperative Jahn-Teller distortions concomitant with staggered 3x^2-r^2/3y^2-r^2 orbital order. We find that the energy gain due to the Jahn-Teller distortion is 82/104 meV per chromium ion in the tetragonal/monoclinic phase, respectively. These phases show A-type magnetic ordering and have a bandgap of 2.48 eV. In this Mott insulating state KCrF_3 has a substantial conduction bandwidth of 2.1 eV, leading to the possibility for the kinetic energy of charge carriers in electron- or hole-doped derivatives of KCrF_3 to overcome the polaron localization at low temperatures, in analogy with the situation encountered in the colossal magnetoresistive manganites.Comment: 7 pages, 11 figure
