Tacit knowledge is widely acknowledged to be an important component of innovation, but such recognition is rarely accompanied by more detailed explanations about the nature of tacit knowledge, why such knowledge is significant, how it becomes codified or whether there may be limits to codification. This paper attempts to fill some of the gaps, drawing on a recent study of university/industry links in three emerging technologies. It concludes that tacit knowledge, which can only be transmitted through personal interaction, will continue (...) to play an important role in innovation. This derives from a variety of reasons, but most significant are the complexity of systems and the emergence of new technologies. (shrink)

This article seeks to open up a new avenue for feminist technology studies—gender-aware research on engineers and engineering practice—on the grounds that engineers are powerful symbols of the equation between masculinity and technology and occupy significant roles in shaping new technologies. Drawing on the disparate evidence available, the author explores four themes. The first asks why the equation between masculinity and technology is so durable when there are such huge mismatches between image and practice. The second examines this mismatch in (...) the detail of engineering knowledge and practice to reveal that fractured and contradictory constructions of masculinity frequently coexist. The third theme addresses the suggestion that women and men might bring different styles to engineering. Finally, the author explores subjective experiences of engineering to argue that engineers’ shared pleasures in and identification with technology both define what it means to be an engineer and provide appealing symbols of power that act to compensate for a perceived lack of power or competence in other arenas.

This paper explores, through empirical research, how values, engineering practices, and technological design decisions shape one another in the development of privacy technologies. We propose the concept of “privacy worlds” to explore the values and design practices of the engineers of one of the world’s most notable privacy technologies: the Tor network. By following Tor’s design and development we show a privacy world emerging—one centered on a construction of privacy understood through the topology of structural power in the Internet backbone. (...) This central “cipher” discourse renders privacy as a problem that can be “solved” through engineering, allowing the translation and representation of different groups of imagined users, adversaries, and technical aspects of the Internet in the language of the system. It also stabilizes a “flattened,” neutralized conception of privacy, risking stripping it of its political and cultural depth. We argue for an enriched empirical focus on design practices in privacy technologies, both as sites where values and material power are shaped, and as a place where the various worlds that will go on to cluster around them—of users, maintainers, and others—are imagined and reconciled.

This article proposes three states in an actor-network and a global/local distinction among actants. This theoretical framework is applied to two invention networks: one created by an inventor of solar heating systems and another created by a designer who wanted to create an environmentally sustainable furniture fabric. Both solar inventor and fabric designer wanted to develop technologies that would improve the environment and also make money. The article concludes by considering whether invention networks that intend to turn “good into gold” (...) have to evolve a shared representation or whether it is sufficient for a new design to serve as a boundary object for actants.

The transformation of existing systems is an underexposed topic in large technical systems research. Most LTS research has focused on the emergence and stabilization of systems, ending with momentum. But how is momentum overcome, and how do transformations come about? This article presents a multilevel perspective to understand such transformations, using insights from STS and evolutionary economics. The multilevel perspective is illustrated with a longitudinal case study of the Dutch highway system.

This article analyzes the relevance of a specific form of social networks, so-called innovative milieus, for the development of radical innovations. Two Swiss initiatives which developed highly energy-efficient means of individual transport in the past ten years are analyzed in terms of the resources they could mobilize and the risks they run. To assess the milieu's potential for radical innovation, we examine the construction of a lightweight safety system, the social construction of the product category "lightweight vehicle, " and the (...) management of the interface between prototype development and large-scale manufacturing.

Radical uncertainty is a concept currently debated, for example, in the economics literature to theorize the impossibility of foreseeing the outcomes of scientific and technological development work. The purpose of this study is to extend the concept to articulate and theorize the minute-to-minute transactions in scientific laboratories. Empirical materials resulting from five years of ethnographic work in one laboratory focusing on fish vision are used to show how scientists produce a material continuity between some natural phenomena and the way they (...) are represented in scientific discourse. Because the outcomes of scientists' actions sometimes turn out to be uncertain, the material actions that produce this continuity themselves retroactively become uncertain. Scientists may at any one point determine that what they had done is not what they thought and said to have done. Actions and the objects they produce therefore stand in a dialectical relationship: they produce, mutually presuppose, and in their respective materiality, stabilize one another. (shrink)

Researchers in science and technology studies appear to be more concerned with descriptions and explanations of social phenomena than with the potential applications of their findings. Science and technology studies should strive to change society by contributing to the design of learning environments that form future generations of producers and consumers of scientific and technological knowledge. In this article, the authors illustrate how they used research findings from science and technology studies to design alternative learning environments and summarize their principal (...) findings from six years of ethnographic research in these learning environments. They conclude by pointing out some of the caveats inherent in theirapproach and by suggesting areas in science education of interest to science and technology studies. (shrink)
