    A Case for Reverse Incorporation of Academic Legal Scholarship into Conflict Management Studies

    Get PDF
    The article takes as its point of departure some of the author’s multidisciplinary projects. Special attention is given to the question of whether the disciplines united in the vari- ous research team members already constituted a kind of ‘inter-discipline’, through which a single object was studied. The issue of how the disciplinary orientations of the research team members occasionally clashed, on methodological issues, is also addressed. The outcomes of these and similar multidisciplinary research projects are followed back into legal practice and academic legal scholarship to uncover whether an incorporation prob- lem indeed exists. Here, special attention will be given to policy recommendations and notably proposals for new leg- islation. After all, according to Van Dijck et al., the typical role model for legal researchers working from an internal perspective on the law is the legislator. The author concludes by making a somewhat bold case for reverse incorporation, that is, the need for (traditional) aca- demic legal research to become an integral part of a more encompassing (inter-)discipline, referred to here as ‘conflict management studies’. Key factors that will contribute to the rise of such a broad (inter-)discipline are the changes that currently permeate legal practice (the target audience of tra- ditional legal research) and the changes in the overall financing of academic research itself (with special reference to the Netherlands)

    alpha'-Corrections to Heterotic Superstring Effective Action Revisited

    Get PDF
    In this letter we establish that the supersymmetric R^2 effective action for the heterotic string, obtained from the supersymmetrisation of the Lorentz Chern-Simons term, is to order α′\alpha' equivalent modulo field redefinitions to heterotic string effective actions computed by different methods.Comment: 7 page

    Scaling Cosmologies of N=8 Gauged Supergravity

    Get PDF
    We construct exact cosmological scaling solutions in N=8 gauged supergravity. We restrict to solutions for which the scalar fields trace out geodesic curves on the scalar manifold. Under these restrictions it is shown that the axionic scalars are necessarily constant. The potential is then a sum of exponentials and has a very specific form that allows for scaling solutions. The scaling solutions describe eternal accelerating and decelerating power-law universes, which are all unstable. An uplift of the solutions to 11-dimensional supergravity is carried out and the resulting timedependent geometries are discussed. In the discussion we briefly comment on the fact that N=2 gauged supergravity allows stable scaling solutions.Comment: 17 pages; referenced added, reportnr changed and some corrections in section

    De evenredigheidstoets bij wettelijk gefixeerde boetestelsels. :Toetsen de Afdeling van de Raad van State en het College van Beroep voor het Bedrijfsleven de hoogte van de boete op vergelijkbare wijze bij wettelijk gefixeerde boetestelsels?

    Onderzocht is of de ABRvS en het CBb de hoogte van een bestuurlijke boete voortvloeiend uit een wettelijk gefixeerde boetestelsel vergelijkbaar toetsen. Het wettelijk gefixeerd boetestelsel houdt in dat de wetgever de hoogte van de boetes per overtreding in een wettelijk voorschrift vastlegt. De wetgever stelt bij het wettelijk gefixeerd boetestelsel dat de wetgever zelf de afweging heeft gemaakt welke boete voor een bepaalde overtreding als evenredig moet worden beschouwd. Bestuur en rechter hebben dan in beginsel geen vrijheid meer om een andere boete op te leggen. Uit de onderzochte jurisprudentie, met name jurisprudentie over de Meststoffenwet (Msw) en financiële toezichtwetgeving, blijkt dat het CBb veel ruimte voor individuele omstandigheden ziet bij de afweging of de hoogte van de boete evenredig is. Daarentegen ziet de ABRvS bij de toetsing van de onderzochte jurisprudentie over de Huisvestingswet (Hvw) geen enkele ruimte voor de omstandigheden van het individuele geval. Zij betrekt alleen financiële draagkracht. Dit is conform de toelichting van de wetgever. De toets die de ABRvS nu hanteert bij de Huisvestingswet lijkt te marginaal om te voldoen aan de eis van ‘full jurisdiction’ uit artikel 6 Europees Verdrag voor de Rechten van de mens (EVRM). Aanbevolen wordt om de systematiek van het CBb toe te passen

    Multiple Membranes from Gauged Supergravity

    Get PDF
    Starting from gauged N=8 supergravity in three dimensions we construct actions for multiple membranes by taking the limit to global supersymmetry for different choices of the embedding tensor. This provides a general framework that reproduces many recent results on multiple membrane actions as well as generalisations thereof. As examples we discuss conformal (non-conformal) gaugings leading to multiple M2-branes (D2-branes) and massive deformations of these systems.Comment: 22 pages, v2: minor changes, reference added, v3: version to appear in JHE

    Chiral superfields in N = 2 supergravity

    Get PDF
    The transformation laws of chiral (scalar) superfields with arbitrary Weyl weight w are determined for the U(2) superconformal theory. A superconformally invariant density is given for fields with w = 2. For w = 1 it is possible to have smaller irreducible multiplets. The full restriction upon which the chiral superfield becomes reducible is exhibited. These results define a complete calculus for the construction of invariant actions with chiral superfields. As an example we find the action for the vector gauge multiplet
