The Anthropocene marks a new geological epoch in which human activity (and specifically Western production and consumption practices) has become a geological force. It also profoundly destabilizes the grounds of Western political philosophy. Visions of a dynamic earth system wholly indifferent to human survival liquefy modernity’s division between nature and politics. Critical thought has only begun to scratch the surface of the Anthropocene’s re-naturalization of politics. This special issue of Resilience: International Policies, Practices and Discourses explores the politics of resilience within the wider cultural and political moment of the Anthropocene. It is within the field of resilience thinking that the implications of the Anthropocene for forms of governance are beginning to be sketched out and experimental practices are undertaken. Foregrounding the Anthropocene imaginary’s re-naturalization of politics enables us to consider the political possibilities of resilience from a different angle, one that is irreducible to neoliberal post-political rule.

As Corporate Reputation (CR) evolves into an important asset for organizations, crises and disasters stand as threats to the preservation of the reputation capital since they usually result to negative projections to their audiences and to problematic evaluations by their stakeholders. Viewing CR as the accumulated trust and positive evaluations of the stakeholders, this paper proposes a conceptual and normative framework for Reputation Continuity, which enhances the ability of organizations to preserve their reputation, instead of working for its recovery in the post-crisis period. In our approach, we propose a process of maintaining trusted links, instead of restoring them and establishing a reputation resilient organization, instead of one struggling to recover from reputation losses, after the crisis has emerged. Working closely with stakeholders during the crisis, injecting a sense of normality continuity through effective leadership and mitigating image problems are seen as critical concerns, alongside a set of managerial practices to be followed. Ultimately, it is argued that, the value-based and strategically integrated view of Business Continuity must be enhanced and supported by Reputation Continuity activities.

We are witnessing nothing less than a revolution in international policy-thinking, with a shift from imagining that international policy-makers can solve development/ security problems through the export or transfer of policy practices or their imposition through conditionality, to understanding that problems should be grasped as emergent consequences of complex social processes which need to be worked with rather than against. This paper, prepared for the 2014 CEPA conference, focuses therefore less on the politicisation and securitisation of questions of conflict and poverty and more on the depoliticisation of questions of conflict and poverty, especially through frameworks of resilience.

I would like to thank Philip Hammond and Julian Reid for their thoughtful reviews. For Reid, the ‘life’ focus of resilience thinking is just another liberal/ neoliberal governmentality, enabling the reproduction and extension of biopolitical rule, thus my book provides interesting insights, but is not necessarily essential for the making of such claims. For Hammond, the conceptual distinctions made in the book shed some useful insights into current discussions of how policy understandings are being transformed and the emergence of the new doxa of complexity and its relational ontology (drawing adherents from across the, now defunct, Left–Right ideological divide).

Over the last decade there has been a shift towards critical understandings of ‘liberal peace’ approaches to international intervention, which argue that local culture holds the key to the effectiveness of peace interventions. In this ‘bottom-up’ approach, peace, reconciliation, and a ‘culture of law’ then become secondary effects of sociocultural norms and values. However, these liberal peace critiques have remained trapped in the paradox of liberal peace: the inability to go beyond the binaries of liberal universalism and cultural relativism. This understanding will be contrasted with the rise of ‘resilience’ approaches to intervention – which build on this attention to the particular context of application but move beyond this paradox through philosophical pragmatism and the focus on concrete social practices. This article clarifies the nature of this shift through the focus on the shifting understanding of international intervention to address the failings of the ‘war on drugs’ in the Americas.

In modernity, failure was the discourse of critique, today, it is increasingly the discourse of power: failure has changed its allegiances. Over the last two decades, failure has been enfolded into discourses of power, facilitating the development of new policy approaches. Foremost among governing approaches that seek to include and to govern through failure is that of resilience. This article seeks to reflect upon how the understanding of failure has become transformed in this process, particularly linking this transformation to the radical appreciation of contingency and of the limits to instrumental cause-and-effect approaches to rule. Whereas modernity was shaped by a contestation over failure as an epistemological boundary, under conditions of contingency and complexity there appears to be a new consensus on failure as an ontological necessity. This problematic ‘ontological turn’ is illustrated using examples of changing approaches to risks, especially anthropogenic understandings of environmental threats, formerly seen as ‘natural’.

Los indicadores de sostenibilidad climática constituyen herramientas fundamentales para complementar las políticas de ordenamiento del territorio urbano y pueden beneficiar la calidad de vida sus habitantes. En el presente trabajo se diseñó un indicador climático urbano para la ciudad de Bahía Blanca considerando variables meteorológicas y análisis de la percepción social. El mismo permitió delimitar la ciudad en cuatro regiones bien diferenciadas entre sí. A partir de entonces, se realizó una propuesta sostenible para mitigar los efectos adversos del clima a partir de la aplicación del método DPSIR. Las mismas estuvieron destinadas a mejorar las condiciones de vida de la población. Los resultados permitieron considerar que una pronta implementación de la misma junto con una activa participación de los actores sociales y los tomadores de decisiones es necesaria para mejorar las condiciones actuales en la que se encuentra la ciudad. Con las medidas propuestas, la población local sabrá cómo actuar ante la ocurrencia de distintos eventos extremos, eventos de desconfort climático, etc. Al ser un método sencillo, la metodología aplicada en este estudio puede replicarse en otras ciudades del mundo con el objetivo de mejorar la calidad de vida de los habitantes.

This talk explores how the runtime system and operating system can leverage metrics that express the significance and resilience of application components in order to reduce the energy footprint of parallel applications. We will explore in particular how software can tolerate and indeed exploit higher error rates in future processors and memory technologies that may operate outside their safe margins.

The observed line intensity ratios of the Si ii λ1263 and λ1307 multiplets to that of Si ii λ1814 in the broad-line region (BLR) of quasars are both an order of magnitude larger than the theoretical values. This was first pointed out by Baldwin et al., who termed it the "Si ii disaster," and it has remained unresolved. We investigate the problem in the light of newly published atomic data for Si ii. Specifically, we perform BLR calculations using several different atomic data sets within the CLOUDY modeling code under optically thick quasar cloud conditions. In addition, we test for selective pumping by the source photons or intrinsic galactic reddening as possible causes for the discrepancy, and we also consider blending with other species. However, we find that none of the options investigated resolve the Si ii disaster, with the potential exception of microturbulent velocity broadening and line blending. We find that a larger microturbulent velocity () may solve the Si ii disaster through continuum pumping and other effects. The CLOUDY models indicate strong blending of the Si ii λ1307 multiplet with emission lines of O i, although the predicted degree of blending is incompatible with the observed λ1263/λ1307 intensity ratios. Clearly, more work is required on the quasar modeling of not just the Si ii lines but also nearby transitions (in particular those of O i) to fully investigate whether blending may be responsible for the Si ii disaster.

Resilience is widely accepted as a desirable system property for cyber-physical systems. However, there are no metrics that can be used to measure the resilience of cyber-physical systems (CPS) while the multi-dimensional nature of performance in these systems is considered. In this work, we present first results towards a resilience metric framework. The key contributions of this framework are threefold: First, it allows to evaluate resilience with respect to different performance indicators that are of interest. Second, complexities that are relevant to the performance indicators of interest, can be intentionally abstracted. Third and final, it supports the identification of reasons for good or bad resilience to improve system design.
