Responsible mission governance: An integrative framework and research agenda

Governance lies at the heart of instigating, steering, and creating the conditions for mission-oriented transitions that potentially help resolve some of our grand societal challenges. In doing so, policymakers will need to navigate both epistemic and normative considerations to develop, implement, and evaluate missions responsibly. A number...

Fallowscapes: A transition-driven tool to market ecological urbanism

Urban areas generate high demand for urban areas to accommodate a broader range of functions associated with growth, given the rising rate of urbanization with more than two-thirds of the human population in 2050 projected to be city-dwellers. As a result, urban areas have been undergoing vigorous spatial, social, and ecological transitions....

Power struggles in policy feedback processes: incremental steps towards a circular economy within Dutch wastewater policy

Environmental problems are usually not tackled with path-departing policies but rather with incrementally adjusted or unchanged policies. One way to address incremental change is the policy feedback approach, which initially focussed on self-reinforcing feedback and path-dependency. Today, self-undermining feedback is also increasingly being...

Using agent-based models to generate transformation knowledge for the German energiewende-potentials and challenges derived from four case studies

The German Energiewende is a deliberate transformation of an established industrial economy towards a nearly CO2-free energy system accompanied by a phase out of nuclear energy. Its governance requires knowledge on how to steer the transition from the existing status quo to the target situation (transformation knowledge). The energy system is,...

Comparison of frequency-domain and continuous-wave near-infrared spectroscopy devices during the immediate transition

Background: Non-invasive monitoring of cerebral tissue oxygen saturation (rcSO₂) during transition is of growing interest. Different near-infrared spectroscopy (NIRS) techniques have been developed to measure rcSO₂. We compared rcSO₂ values during the immediate transition in preterm neonates measured with...

Patterns of Circular Transition: What Is the Circular Economy Maturity of Belgian Ports?

Large seaport hubs in Northwestern Europe are aiming to develop as circular hotspots and are striving to become first movers in the circular economy (CE) transition. In order to facilitate their transition, it is therefore relevant to unravel potential patterns of the circular transition that ports are currently undertaking. In this paper, we...

Experimenting with a circular business model: Lessons from eight cases

Experimentation is an important capability in the transition to a sustainable business. The aim of business experimentation is to learn and improve business model innovation activities with limited risks and resources through continuous and collective learning with stakeholders. Through action research we worked with eight case companies on a...

Drag reduction by laminar flow control

The Energy System Transition in Aviation research project of the Aeronautics Research Center Niedersachsen (NFL) searches for potentially game-changing technologies to reduce the carbon footprint of aviation by promoting and enabling new propulsion and drag reduction technologies. The greatest potential for aerodynamic drag reduction is seen...

Geometry effect of isolated roughness on boundary layer transition investigated by tomographic PIV

Boundary layer transition over isolated roughness elements is investigated in the incompressible flow regime using tomographic PIV. Four different geometries (cylinder, square, hemisphere and micro-ramp) are considered maintaining constant height and span of the element. The main target is to compare the different flow topologies and study the...
