    The non-microstates free entropy dimension of DT-operators

    Get PDF
    Dykema and Haagerup introduced the class of DT-operators and also showed that every DT-operator generate the von Neumann algebra generated by the free group on two generators. In this paper we prove that Voiculescu's non-microstates free entropy dimension is 2 for all DT-operators.Comment: 30 page

    Environmental Law\u27s Heartland and Frontiers

    This short paper offers three propositions to help maintain the traditional core of environmental law while also expanding environmental concerns into the frontiers of the field: 1. Environmental law in the heartland and environmental law at the frontiers of the field differ in important ways. 2. The distinctive features of the heartland and frontiers provide important functional benefits for the adaptive development of environmental law in each respective area. 3. Maintaining a distinctive heartland and frontiers of environmental law creates a dialectic relationship between the two that includes tension but also, if properly managed, potential synergies. The locus of innovation moving forward is likely to be outside of the traditional domain of environmental law--in areas that are at the frontiers of environmental law, but in the heart of related fields such as energy law, corporate social responsibility, and insurance. At the same time, environmental law\u27s heartland will continue to dominate the regulation of environmental harms for the foreseeable future. The future of environmental law therefore will be determined by a dialectic relationship between the heartland and frontiers of environmental law; each playing its own crucial role in the development of the field, in tension but also significantly dependent on the other

    Environmental Harms, Use Conflicts, and Neutral Baselines in Environmental Law

    Accounts of environmental law that rely on concepts of environmental harm and environmental protection oversimplify the tremendous variety of uses of environmental resources and the often complex relationships among those uses. Such approaches are analytically unclear and, more importantly, insert hidden normativity into putatively descriptive claims. Instead of thinking about environmental law in terms of preventing environmental harm, environmental problems can be understood more specifically and more meaningfully as disputes over conflicting uses of environmental resources. This Article proposes a use-conflict framework as a means of acquiring a deeper understanding of environmental problems and lawmaking without favoring any particular normative approach. The framework does not itself propose a resolution of any environmental problems but rather describes environmental problems and environmental lawmaking conceptually in a manner that exposes normative claims and attempts to establish some common ground across diverse normative perspectives

    The Complexity Dilemma in Policy Market Design

    Get PDF
    Regulators are increasingly pursuing their policy objectives by creating markets. To create a policy market, regulators require firms to procure a product that is socially useful but that confers little direct private benefit to the acquiring party. Examples of policy markets include pollutant emissions trading programs, renewable energy credit markets, and electricity capacity markets. Existing scholarship has tended to analyze policy markets simply as market-based regulation. Although not inaccurate, such inquiries are necessarily incomplete because they do not focus on the distinctive traits of policy markets. Policy markets are neither typical regulations nor typical markets. Concentrating on policy markets as a distinctive type of market brings to light common characteristics of such markets, which in turn generates insights into how they can be used more effectively to implement policy. In particular, this Article focuses on a recurring fundamental challenge in policy market design: managing complexity. Typical markets manage complexity through market forces. As a regulatory creation, however, policy markets require regulators to manage their complexity. This poses what we call the complexity dilemma, which requires regulators to balance strong pressures both toward and away from complexity. The central argument of this Article is that although policy markets are an important part of a regulator’s toolkit, they are also subject to complexity that limits their usefulness. Understanding the complexity dilemma and its crucial role in policy market design forms an essential step toward progress in improving the design and function of these markets

    A numerical ocean circulation model of the Norwegian and Greenland Seas

    Get PDF
    The dynamics and thermodynamics of the Norwegian and Greenland Seas are investigated using a three-dimensional primitive equation ocean circulation model. The horizontal resolution of the model is 1° in the zonal direction and 0.5° in the meridional direction. The vertical structure is described by 15 levels. The model is driven by both annual mean and seasonally varying wind and thermohaline forcing. The connections of the Norwegian and Greenland Seas with the North Atlantic and Arctic Ocean are modelled with an open boundary condition. The simulated currents are in reasonable agreement with the observed circulation
