The Special Issue consolidates new approaches to the study of the EU’s role in the eastern neighbourhood and beyond, informed by post-structuralist traditions in international relations. More specifically, by revisiting the European Neighbourhood Policy’s agenda from the conceptual perspective of ‘the political’ and redefining the notions of ‘othering’, ‘differentiation’ and ‘normalisation’, this volume renders a new and much-needed theoretical and empirical outlook onto the policy developments and their practices. By unpacking and connecting security, regional, institutional, normative and sector-thematic policy dimensions, the book seeks to re-politicise the agenda and re-focus policy revision on understanding the fundamentals of power relations when applied to the EU external relations. In light of the compounding crises, external and internal, one can no longer afford to simply tinker around the edges of the policy content and instruments. A more radical theoretical undertaking is overdue, to re-shape, re-define and re-centre the EU relations with the eastern region especially, put in the context of the new EU’s Global Security Strategy, and the new aspirations for the 2017 European Neighbourhood summit.

The chapters originally published as a special issue in East European Politics.

Wilson lines (also known as gauge links or eikonal lines) can be introduced in any gauge field theory. Although the concept of the Wilson exponentials finds an enormously wide range of applications in a variety of branches of modern quantum field theory, from condensed matter and lattice simulations to quantum chromodynamics, high-energy effective theories and gravity, there are surprisingly few books or textbooks on the market which contain comprehensive pedagogical introduction and consecutive exposition of the subject. The objective of this book is to get the potential reader acquainted with theoretical and mathematical foundations of the concept of the Wilson loops in the context of modern quantum field theory, to teach him/her to perform independently some elementary calculations with Wilson lines, and to familiarize him/her with the recent development of the subject in different important areas of research. The target audience of the book consists of graduate and postgraduate students working in various areas of quantum field theory, as well as researchers from other fields.

The purpose of this book is to give a systematic pedagogical exposition of the quantitative analysis of Wilson lines and gauge-invariant correlation functions in quantum chromodynamics. Using techniques from the previous volume (Wilson Lines in Quantum Field Theory, 2014), an ab initio methodology is developed and practical tools for its implementation are presented. Emphasis is put on the implications of gauge invariance and path-dependence properties of transverse-momentum dependent parton density functions. The latter are associated with the QCD factorization approach to semi-inclusive hadronic processes, studied at currently operating and planned experimental facilities.

Decision makers in large scale interconnected network systems require simulation models for decision support. The behaviour of these systems is determined by many actors, situated in a dynamic, multi-actor, multi-objective and multi-level environment. How can such systems be modelled and how can the socio-technical complexity be captured? Agent-based modelling is a proven approach to handle this challenge. This book provides a practical introduction to agent-based modelling of socio-technical systems, based on a methodology that has been developed at TU Delft and which has been deployed in a large number of case studies. The book consists of two parts: the first presents the background, theory and methodology as well as practical guidelines and procedures for building models. In the second part this theory is applied to a number of case studies, where for each model the development steps are presented extensively, preparing the reader for creating own models.
