Reflections on the role of energy network companies in the energy transition

Background Energy network companies are commonly attributed the public task to help society in becoming greener in the domain of energy. This extra public task has high costs and comes with high uncertainties. It may also compete with existing public tasks of network companies. When network companies are involved in local green initiatives, they...

The Politics of Resilience in the Dutch ‘Room for the River’-project

An increased focus on the concept of resilience in flood protection has led to the development of a comprehensive flood protection strategy in the Netherlands which stresses the need to provide ‘Room for the River’ rather than building dykes. But how can a resilient solution in flood protection be successfully implemented? Using insights from...

Waarom worstelen netbeheerders met de energietransitie? Vijf holle antwoorden en een empirisch perspectief

In dit essay betogen we dat de rol van netbeheerders in de energiesector verre van glashelder is. Dit blijkt in het bijzonder als we nagaan hoe netbeheerders de energietransitie op lokaal en regionaal niveau zouden moeten faciliteren. Heersende rolopvattingen vanuit juridisch, politiek, beleidsmatig, economisch of technisch oogpunt zijn...

Atherosclerotic Plaque Component Segmentation in Combined Carotid MRI and CTA Data Incorporating Class Label Uncertainty

Atherosclerotic plaque composition can indicate plaque vulnerability. We segment atherosclerotic plaque components from the carotid artery on a combination of in vivo MRI and CT-angiography (CTA) data using supervised voxelwise classification. In contrast to previous studies the ground truth for training is directly obtained from 3D registration...

Plaque characterization in ex vivo MRI evaluated by dense 3D correspondence with histology

Automatic quantification of carotid artery plaque composition is important in the development of methods that distinguish vulnerable from stable plaques. MRI has shown to be capable of imaging different components noninvasively. We present a new plaque classification method which uses 3D registration of histology data with ex vivo MRI data,...

Dealing with Dilemma’s: How Can Experiments Contribute to a More Sustainable Mobility System?

Sustainable mobility has proved to be a perennial challenge to realize. Scholars have argued that experiments could point the way forward towards sustainable mobility (cf. Loorbach, 2007, Markard and Truffer, 2008). In doing so, literature attributes a vital but complex task to those who engage in experiments. However, an important knowledge gap...

Hoe écht is een virtuele crisis? De rol van serious gaming in crisis- en rampenbestrijding

In het Bestuurskunde themanummer over ‘spelsimulaties’ in 1995 werd een visionair beeld geschetst van het experimenteel oefenen van ‘virtual reality’. In dit artikel analyseren we of deze toekomstvisie is uitgekomen. Wat is de rol van serious gaming in crisismanagement en rampenbestrijding? Hoe écht is zo’n virtuele crisis nu precies? We laten...

The Brittleness of Unbundled Train Systems: Crumbling Operational Coping Strategies

This paper reports on the current status of the restructured Dutch rail sector. We empirically studied the strategies traffic controllers display to cope with daily value-conflicts in rail operations, at infrastructure manager ProRail and train operating company NS. We use a new framework to identify types of coping behavior. The findings are...

Systems that Should Have Failed: Critical Infrastructure Protection in an Institutionally Fragmented Environment

Recent years have witnessed major governmental initiatives regarding Critical Infrastructure Protection (CIP). At the same time, critical infrastructures have undergone massive institutional restructuring under the headings of privatization, deregulation and liberalization. Little research has gone into understanding the interactions between...

Networked reliability: Institutional fragmentation and the reliability of service provision in critical infrastructures

Critical Infrastructures are the arteries and veins of Western, urbanized societies. The services and products provided by these large-scale, complex systems are considered essential. However, in recent years, more and more new problems seem to crop op after these infrastructures were opened up to market forces. What has happened in these...
