The roots of neo-liberal resilience: Explaining continuity and change in background ideas in Europe's political economy

Neo-liberalism has come to constitute the core background idea of European political economies, as the unquestioned set of beliefs, understandings, or core philosophy exercising a seemingly incontrovertible hold since the 1980s in Europe. Using a discursive institutionalist framework, this article defines background ideas; describes their different forms, levels, and types; theorizes about the nature of continuity and change in such ideas; and considers the agents and discursive processes through which such ideas are constructed and disseminated. It illustrates throughout with examples of neo-liberalism, from the philosophical origins through its many different permutations in different institutional contexts over time. This article concludes that although ‘background ideas’ as a concept remains somewhat elusive, it is nonetheless useful as a way of understanding how neo-liberalism has managed to infuse people’s deepest assumptions about the possible and thereby to set the limits of the imaginable with regard to political economic action.Accepted manuscrip

The Effect of Void Structure on the Permeability of Fibrous Networks

A Kozeny–Carman-based model of permeability for fibrous networks is proposed: the original model is extended by incorporating information about the local structure of the void space. Furthermore, it is demonstrated how in practice this added structural information can be retrieved from a three-dimensional digital image of a fibrous material. The proposed model is then validated for both foam- and water-deposited laboratory sheets of bleached kraft pulp (Scots pine) and chemi-thermo-mechanical pulp (CTMP, Norway spruce). The validation is carried out by comparing the model predictions against computationally determined permeability values. The related fluid-flow simulations are executed using the lattice-Boltzmann method together with high-resolution X-ray microtomography images. For both pulp materials, the sample sets had nearly equal porosities, but deviated substantially in their permeabilities. The proposed model was shown to improve prediction of permeability for the fibrous materials considered: the deviation between the predicted and computationally determined values was no more than 8%
