Alternative Systems of Crime Control. National, Transnational, and International Dimensions

The typical trial-oriented systems of criminal justice that are primarily based on the strict application of substantive criminal law have reached their functional and logistical limits in most parts of the modern legal world. As a result, new sanction models, less formal, administrative, and discretionary case disposals, plea bargaining arrangements, and other alternative procedural and transitional justice mechanisms have emerged at unprecedented levels in national and international legal orders affiliated both with the civil law and the common law tradition. These normative constructs and practices aim at abbreviating, simplifying, or circumventing the conventional criminal investigation and prosecution. They seek to enhance the effectiveness of conflict resolution proceedings and to shift the focus of crime control from repression to prevention. The present volume explores these alternative, informal, preventive, and transitional types of criminal justice and the legitimacy of new sanction models in the global risk society from the perspective of national and international justice and by focusing on the special regimes of anti-terrorism measures and security law. The authors of the papers are experts and internationally acclaimed scholars in this field. Their research results were presented and discussed at an inter-national conference held on 26-27 January 2018 at Middle Temple in London, UK, which was organized by the School of Law of the Queen Mary University of London, the Max Planck Institute for Foreign and International Criminal Law (Freiburg), and the European & International Criminal Law Institute (Athens)

Evaluation of a high-resolution regional climate simulation over Greenland

A simulation of the 1991 summer has been performed over south Greenland with a coupled atmosphere–snow regional climate model (RCM) forced by the ECMWF re-analysis. The simulation is evaluated with in-situ coastal and ice-sheet atmospheric and glaciological observations. Modelled air temperature, specific humidity, wind speed and radiative fluxes are in good agreement with the available observations, although uncertainties in the radiative transfer scheme need further investigation to improve the model’s performance. In the sub-surface snow-ice model, surface albedo is calculated from the simulated snow grain shape and size, snow depth, meltwater accumulation, cloudiness and ice albedo. The use of snow metamorphism processes allows a realistic modelling of the temporal variations in the surface albedo during both melting periods and accumulation events. Concerning the surface albedo, the main finding is that an accurate albedo simulation during the melting season strongly depends on a proper initialization of the surface conditions which mainly result from winter accumulation processes. Furthermore, in a sensitivity experiment with a constant 0.8 albedo over the whole ice sheet, the average amount of melt decreased by more than 60%, which highlights the importance of a correctly simulated surface albedo. The use of this coupled atmosphere–snow RCM offers new perspectives in the study of the Greenland surface mass balance due to the represented feedback between the surface climate and the surface albedo, which is the most sensitive parameter in energy-balance-based ablation calculations.Peer reviewe

Amplified melt and flow of the Greenland ice sheet driven by late-summer cyclonic rainfall

Intense rainfall events significantly affect Alpine and Alaskan glaciers through enhanced melting, ice-flow acceleration and subglacial sediment erosion, yet their impact on the Greenland ice sheet has not been assessed. Here we present measurements of ice velocity, subglacial water pressure and meteorological variables from the western margin of the Greenland ice sheet during a week of warm, wet cyclonic weather in late August and early September 2011. We find that extreme surface runoff from melt and rainfall led to a widespread acceleration in ice flow that extended 140 km into the ice-sheet interior. We suggest that the late-season timing was critical in promoting rapid runoff across an extensive bare ice surface that overwhelmed a subglacial hydrological system in transition to a less-efficient winter mode. Reanalysis data reveal that similar cyclonic weather conditions prevailed across southern and western Greenland during this time, and we observe a corresponding ice-flow response at all land- and marine-terminating glaciers in these regions for which data are available. Given that the advection of warm, moist air masses and rainfall over Greenland is expected to become more frequent in the coming decades, our findings portend a previously unforeseen vulnerability of the Greenland ice sheet to climate change
