Open Wilson Lines and Group Theory of Noncommutative Yang-Mills Theory in Two Dimensions
The correlation functions of open Wilson line operators in two-dimensional
Yang-Mills theory on the noncommutative torus are computed exactly. The
correlators are expressed in two equivalent forms. An instanton expansion
involves only topological numbers of Heisenberg modules and enables extraction
of the weak-coupling limit of the gauge theory. A dual algebraic expansion
involves only group theoretic quantities, winding numbers and translational
zero modes, and enables analysis of the strong-coupling limit of the gauge
theory and the high-momentum behaviour of open Wilson lines. The dual
expressions can be interpreted physically as exact sums over contributions from
virtual electric dipole quanta.Comment: 37 pages. References adde

Vilhelm Lundstedt’s ‘Legal Machinery’ and the Demise of Juristic Practice
This article aims to contribute to the academic debate on the general crisis faced by law schools and the legal professions by discussing why juristic practice is a matter of experience rather than knowledge. Through a critical contextualisation of Vilhelm Lundstedt’s thought under processes of globalisation and transnationalism, it is argued that the demise of the jurist’s function is related to law’s scientification as brought about by the metaphysical construction of reality. The suggested roadmap will in turn reveal that the current voiding of juristic practice and its teaching is part of the crisis regarding what makes us human
Scientific Advice to Public Policy-Making
A feature of policy-making today is its dependence on scientific advice to deliver public policies that are robust, credible, and effective. This paper discusses how policy-making profits from scientific advice in areas where science and technology are significant. Particular attention is given to issues holding a high level of uncertainty, either because of inherent variability, because science is incomplete or controversial, or because data are inadequate to support a definitive answer. First, we analyse the social context that characterises the relationship between science and policy-making, with a focus on the decrease of public confidence in politicians and scientists. Second, we compare three different sets of guidelines on the collection and use of expertise in policy-making (issued by the UK, Canada and the European Commission, respectively) and identify two different approaches to scientific advice in policy-making. Third, based on a set of cross-national and multi-disciplinary case studies, we look at how the relationship between science and policy-making works in practice and propose a set of recommendations towards the establishment of a more robust and effective policy-making process
