Megaproject Environmentally Responsible Behavior in China: A Test of the Theory of Planned Behavior

Construction megaprojects play a significant role in today’s infrastructure provision in terms of sustainable development, and their increasing proliferation worldwide means the environmentally responsible behavior (ERB) of those involved are becoming of vital importance. This study investigates how ERB can be best supported in megaprojects by first identifying the motivational factors that are involved based on the theory of planned behavior (TPB), followed by a survey of 188 managers involved in China megaprojects to test the TPB model using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results strongly support the TPB model’s predictive ability, with subjective norms being the strongest predictors, followed by attitudes and perceived behavioral control. These findings provide support for decision makers in helping to cultivate and improve the level of megaproject ERB in China and many other such countries that are similarly involved.

Working at the boundary: Making space for innovation in a NASA megaproject

This study shows how occupational, organizational and institutional boundaries can be reworked to enable innovation. Based on an historical case study of NASA's Spitzer Space Telescope, which spanned three decades and two dozen organizations, I show how megaproject members made boundaries a target of strategic action. Megaprojects, in particular, require us to think about boundaries at multiple levels as they commonly draw on expertise and resources from different disciplines, organizations, and institutional domains. This case reveals several mechanisms by which boundaries can be modified to coordinate diverse innovation partners, from reconfiguring the ways members relate to one another (splicing, fitting and channeling) to reshaping the environment they work in (softening, fusing and corralling). Overall, this study contributes to our understanding of how actors make room for new ideas and cause institutional change as part of innovation processes. By treating boundaries as malleable and multiplex, I extend organizational theory, which tends to view boundaries as given and things to be spanned. I extend the STS literature that takes boundaries as fluid, identifying several mechanisms of making and unmaking them. A more dynamic treatment of boundaries is called for in both innovation research and practice, and this study opens a path for research that looks not only at boundary objects but also boundary actions, and moves from boundary organizations to boundary organizing.

Reconfiguration, Contestation, and Decline: Conceptualizing Mature Large Technical Systems

Large technical systems (LTS) are integral to modern lifestyles but arduous to analyze. In this paper, we advance a conceptualization of LTS using the notion of mature "phases," drawing from insights into innovation studies, science and technology studies, political science, the sociology of infrastructure, history of technology, and governance. We begin by defining LTS as a unit of analysis and explaining its conceptual utility and novelty, situating it among other prominent sociotechnical theories. Next, we argue that after LTS have moved through the (overlapping) phases proposed by Thomas Hughes of invention, expansion, growth, momentum, and style, mature LTS undergo the additional (overlapping) phases of reconfiguration, contestation (subject to pressures such as drift and crisis), and eventually stagnation and decline. We illustrate these analytical phases with historical case studies and the conceptual literature, and close by suggesting future research to refine and develop the LTS framework, particularly related to more refined typologies, temporal dimensions, and a broadening of system users. We aim to contribute to theoretical debates about the coevolution of LTS as well as empirical discussions about system-related use, sociotechnical change, and policy-making.
