In the coming decades, highly treated wastewater, known as reclaimed water, is slated to be a major element of municipal water supplies. In particular, planners propose supplementing drinking water with reclaimed water as a sustainable solution to the growing challenge of urban water scarcity. Public opposition is currently considered the primary barrier to implementing successful potable water reuse projects; nonetheless, public responses to reclaimed water are not well understood. Based on a survey of over 250 residents of Tucson, Arizona, this (...) article assesses the relationship between trust in the professional institutions responsible for municipal water development and willingness to drink reclaimed water. Results demonstrate that public acceptance of potable reuse is contingent on trust in the authorities who influence design of sociotechnical systems for water supply and reuse—including water and wastewater utilities, regulators, consultants, academics, and elected local officials. Findings emphasize the highly interdependent social and political factors that inform personal decisions to support or reject potable reuse. The authors suggest that achieving greater acceptance of potable reuse will require bringing local and regional water policy in line with public values, as well as finding ways to incorporate these values into the planning process.

Political responses to metropolitan growth in the United States and elsewhere should include careful ethical deliberation, but ethical judgment and action are limited by the involvement of individual moral agents in the complex processes that give shape to the built environment. I propose that casting the built environment as a heterogeneous sociotechnical ensemble can provide useful insight into the limits of ethics, particularly through the concept of obduracy. To the extent components of an ensemble are obdurate, they can stop or (...) deflect even well-considered actions even as they impose constraints on moral agency itself. From this possibility spring a number of worthwhile lines of inquiry at the confluence of ethics and technology studies. (shrink)

Many recent studies on network technologies and cities share an alarmist view of the impact of technological or regulatory change in utility sectors on the social and spatial fabric of cities, pointing to growing discrimination and inequalities, alienation, enhanced social exclusion and urban “splintering” on a universal scale. A science and technology study perspective on these matters is helpful in moving beyond this “universal alarmism” by emphasizing the ambivalence inherent to all technologies, the significant potential of contestation of, and resistance, (...) to technology-supported forms of discrimination, and the deeply contingent nature of the process of appropriation of new technologies and, as a consequence, of the social “effects” of technologies. Adopting this perspective would mean actively searching for and exploring these context-dependent and often conflictive appropriation processes. For it is in these spaces that we might begin to identify urban technological politics that break free from an intellectually and politically disabling technological pessimism. (shrink)

It has been convincingly argued that computer simulation modeling differs from traditional science. If we understand simulation modeling as a new way of doing science, the manner in which scientists learn about the world through models must also be considered differently. This article examines how researchers learn about environmental processes through computer simulation modeling. Suggesting a conceptual framework anchored in a performative philosophical approach, we examine two modeling projects undertaken by research teams in England, both aiming to inform flood risk (...) management. One of the modeling teams operated in the research wing of a consultancy firm, the other were university scientists taking part in an interdisciplinary project experimenting with public engagement. We found that in the first context the use of standardized software was critical to the process of improvisation, the obstacles emerging in the process concerned data and were resolved through exploiting affordances for generating, organizing, and combining scientific information in new ways. In the second context, an environmental competency group, obstacles were related to the computer program and affordances emerged in the combination of experience-based knowledge with the scientists’ skill enabling a reconfiguration of the mathematical structure of the model, allowing the group to learn about local flooding.

The article aims for examining the ‘technological stasis’ of the data structure in OpenStreetMap – the successful global collaborative geodata project devoted to ‘create and distribute free geographic data for the world’. Digital structures are strongly influenced by continuing stagnation. This technological stasis – the lack of change in technology – influences data in various ways, as demonstrated by the intensive discussion of the issue by computer scientists and software engineers. However, existing research describing stagnating software is often technic centred (...) and fuzzy, while critical research is barely considering issues of technological stasis in the digital context at all. Therefore, this paper aims for enriching this body of knowledge in order to shed light on aging data structures. I reframe technological stasis with a social-constructivist perspective – using the approach of Social Construction of Technology – especially with the concept of technological frames. Based on the case example of OpenStreetMap, my findings suggest that the data structure – and its stasis – is the outcome of competing understandings and perspectives, shaped by power asymmetries. Although the data structure did not significantly change for more than 10 years, I demonstrate that this is not because of a lack of motivation, nor technological difficulties of carrying out such changes. The technological stasis is rather rooted in the dominant position of few project members who are able to change the software design; it is their perception of the project that defines how data should be stored and what features are dispensable.
