Th is book celebrates – while also acknowledging the huge challenges it faces – a particular kind of feminism, one that has been concerned with challenging both fundamentalism and racism. It consists of the autobiographical political narratives of feminist activists of diff erent ethnic and religious backgrounds who have been members of Women Against Fundamentalism (WAF), a feminist anti-racist and antifundamentalist organisation that was established in London in 1989, at the heart of the Salman Rushdie aff air. Political narratives have been described as ‘stories people tell about how the world works’, the ways in which they explain the engines of political change, and as refl ections on the role people see themselves and their group playing in their ongoing struggles.1 And the contributors to this book off er just such narratives – they talk about the trajectories of their lives, and how they see themselves and the groups to which they belong in relation to the wider political struggles in which they have been involved. WAF women have shared solidarity and trust, based on common political values, but, as can be seen from the chapters of this book, their perspectives – as well as their personal/ political histories – have also diff ered.2 Th is variety of voices is signifi - cant not only for these women as individuals but also for WAF as a political organisation. In this introduction we highlight what we as editors perceive to be the most important issues for WAF’s activism throughout its history. However, the book has been constructed in such a way that reading all the chapters will itself provide a more pluralistic and contested fl avour of WAF’s politics. Th is introduction outlines the rationale for the book, introduces WAF and its political context, explains the book’s theoretical and methodological framework, and explores some of the themes that have emerged from the activists’ stories.

Loess is the most important collapsible soil; possibly the only engineering soil in which real collapse occurs. A real collapse involves a diminution in volume - it would be an open metastable packing being reduced to a more closely packed, more stable structure. Metastability is at the heart of the collapsible soils problem. To envisage and to model the collapse process in a metastable medium, knowledge is required about the nature and shape of the particles, the types of packings they assume (real and ideal), and the nature of the collapse process - a packing transition upon a change to the effective stress in a media of double porosity. Particle packing science has made little progress in geoscience discipline - since the initial packing paradigms set by Graton and Fraser (1935) - nevertheless is relatively well-established in the soft matter physics discipline. The collapse process can be represented by mathematical modelling of packing – including the Monte Carlo simulations - but relating representation to process remains difficult. This paper revisits the problem of sudden packing transition from a micro-physico-mechanical viewpoint (i.e. collapse imetan terms of structure-based effective stress). This cross-disciplinary approach helps in generalization on collapsible soils to be made that suggests loess is the only truly collapsible soil, because it is only loess which is so totally influenced by the packing essence of the formation process.
