Design and sparing techniques to meet specified performance life

Specified performance life technique starts with the general description of what is wanted, defines in block diagram the operational needs, and then defines the functional systems required. The technique is similar to a truncated reliability model, but the calculation is simplified by use of a Poisson distribution approach to failure probability

Environmental governance on the street : towards an expanded research agenda on street-level bureaucrats

Funding: Scottish Government Hydro Nation Scholars Programme (KH).Research on environmental governance would benefit from greater attention to the practices, agency and subjectivities of the frontline civil servants who implement and shape environmental policies and interventions on the ground. These actors conduct the everyday work of bringing global agreements and state policies into being. In doing so, they influence how citizens experience the state and environmental governance. In this review paper, we provide a brief overview of existing literature on ‘street-level bureaucrats’ (SLBs). We then suggest three key research areas through which insights into the role of SLBs in environmental governance could be further developed, including (i) the nature of SLBs agency and practice as they enact global and national environmental agendas, (ii) the subjectivities of SLBs and how they affect environmental governance and (iii) the outcomes of the activities of SLBs on state-citizen relations. This research agenda has explanatory power in understanding existing and desired environmental governance.Publisher PDFPeer reviewe

Community-led initiatives’ everyday politics for sustainability – Conflicting rationalities and aspirations for change?

This project has received funding from the European Union’s 7th Framework Programme for Research, Technological Development and Demonstration (Grant Agreement no. 603705) through TESS (Towards European Social Sustainability, http://www.tess-transition.eu/).Community-based initiatives are widely seen to play an essential role in a societal move towards a low carbon, sustainable future. As part of this, there is often an assumption that such initiatives share expectations (i.e. a guiding vision) of large-scale change and that their activities contribute to this change. Here, we ask to what extent this assumption reflects members’ own perspectives on and interpretations of the aims and ambitions of their community initiative, and what this implies for a larger vision of sustainability transitions. In doing so, we respond to calls for a better understanding of the ‘everyday politics’ of what could be seen as processes of societal transitions in practice. We conducted qualitative interviews with members of five community initiatives in Italy, Finland and the UK. In each of these initiatives, we found a range of aspirations (i.e. outcome-related aims) and rationalities (i.e. procedural guiding principles). While some of these aims and ways of working were compatible with each other, we identified three major tensions that could be found across our study initiatives. These tensions centred on (i) the degree of politicisation of the initiative, (ii) the extent to which financial aims should take priority and (iii) questions of organisational form. We interpret these tensions as conflicting expressions of larger, societal-level discourses, and argue that this diversity and resulting conflicts need to be acknowledged – both in transition research and at the practical level – to avoid co-optation and disenfranchisement.PostprintPeer reviewe

Challenges to enabling and implementing Natural Flood Management in Scotland

The research for this paper was supported by the Scottish Government RESAS Strategic Research Programme 2011–2016.We explore factors that constrain implementation of Natural Flood Management (NFM), based on qualitative analysis of interviews with those influencing and enabling flood risk management in Scotland. NFM entails collaboration by multiple individuals and organisations to plan and deliver measures such as re-meandering or buffer strips. Our interviewees identified many interacting issues. They particularly focused on difficulties in securing resources, and evidence gaps and uncertainties associated with NFM. Co-ordination was not simple, often requiring new types of skill, expertise, and resources. NFM is thus outside the ‘comfort zone’ of many leading or engaged with flood risk management. These experiences echo and elaborate on other studies of attempts to encourage sustainable flood management. To tackle these challenges, practitioners should reflect how pre-existing ideas and practices may shape and constrain new approaches to managing floods, while research is needed on specific strategies that can assist in enabling change.Publisher PDFPeer reviewe

Resocializing digital water transformations : outlining social science perspectives on the digital water journey

Funding information: National Cyber Security Centre; Scottish Government, Grant/Award Number: Hydro Nation Scholars; University of Manchester, Grant/Award Number: Presidential fellowship; University of Manchester, Grant/Award Number: SEED PGR scholarship (Amankwaa).Digital water transformation is often written about as though universally desirable and inevitable, capable of addressing the multifaceted socioecological challenges that water systems face. However, there is not widespread reflection on the complexities, tensions and unintended consequences of digital transformation, its social and political dimensions are often neglected. This article introduces case studies of digital water development, bringing examples of technological innovation into dialogue with literature and empirical research from across the social sciences. We examine how Big Data affects our observations of water in society to shape water management, how the Internet of Things becomes involved in reproducing unjust water politics, how digital platforms are entangled in the varied sociocultural landscape of everyday water use, and how opensource technologies provide new possibilities for participatory water governance. We also reflect on regulatory developments and the possible trajectories of innovation resulting from public‐private sector interactions. A socially and politically informed view of digital water is essential for just and sustainable development, and the gap between industry visions of digital water and research within the social sciences is inhibitive. Thus, the analysis presented in this article provides a novel, pluralistic perspective on digital water development and outlines what is required for more inclusive future scholarship, policy and practice.Publisher PDFPeer reviewe

‘Shift happens’: Co-constructing transition pathways towards the regional sustainability of agriculture in Europe

Farming systems have to face challenges that originate in changes of global dimension in both the bio-physical and the societal sphere, such as Climate change (leading to increasing weather uncertainty and raising average temperatures, thus impacting agro-ecosystems and water supplies); Food safety concerns (spreading in Europe while in other regions food security remains a challenge) and Changing consumption patterns and unequal purchasing power (contributing to the unsustainable use of natural resources in many countries). These changes have manifold implications and raise many questions with regard to agricultural land use

Researching climate change and community in neoliberal contexts: an emerging critical approach

In a 2011 contribution to this journal, Walker examined the ways that community is routinely employed in carbon governance, suggesting the need for more critical approaches. Here, we characterize an emerging, critical approach to researching climate change and community in neoliberal contexts, focusing attention principally on the global north, where this body of research has emerged. This work recognizes communities as sites of contestation, difference, tension, and distinction, in which action on climate change can be designed to meet a range of political and public ends. It aims to uncover the political and social context for community action on climate change, to be alert to the power relations inside and outside of communities, and to the context of neoliberalism, including individualism, the will to quantify, and competition. Furthermore, research in this space is committed to understanding both the lived experience of the messy empirical worlds we encounter, and the potential agency coalescing in community responses to climate change. Much of the work to date, discussed here, has focused on communities working on climate change mitigation in the global north, in which the idea of community as a space for governance is gaining traction. We also comment on the positioning of these arguments in the context of long-standing debates in the fields of ‘community-based’ development, natural resource management, and adaptation in the global South. This discussion establishes a foundation from which to progress learning across fields and geopolitical boundaries, furthering critical thinking on ‘community.
