In the perspective of a sustainable urban planning, it is necessary to investigate cities in a holistic way and to accept surprises in the response of urban environments to a particular set of strategies. For example, the process of inner-city densification may limit air pollution, carbon emissions, and energy use through reduced transportation; on the other hand, the resulting…

There is growing interest in discrete-choice experiment (DCE) as a method to elicit consumers' preferences in the health care sector. Increasingly this method is used to determine willingness to pay (WTP) for health-related goods. However, its external validity in the health care domain has not been investigated until now. This paper examines the external validity of DCE…

This paper analyzes the relationship between the diffusion of new technologies and the decentralization of firms. Centralized control relies on the information of the principal, which we equate with publicly available information. Decentralized control, on the other hand, delegates authority to a manager with superior information. However, the manager can use her informational…

Mobile health systems extend the Enterprise Computing System (ECS) of the healthcare provider by bringing services to the patient anytime and anywhere. We propose a methodology for the development of such extended ECSs which applies a model-driven design and development approach augmented with formal Validation and Verification (V&V) to address quality and correctness and to…

This volume contains all accepted papers of the ERCIM Workshop on eMobility, which has been held in Coimbra, Portugal, on May 21, 2007. Papers from three main areas have been selected for the workshop. The workshop papers discuss several topics of the ERCIM eMobility working group, namely – Traffic engineering and mobility management – Wireless (sensor) networks – Pervasive computing…

Hovering information is a new concept denoting information that stays attached to a specific geographical location rather than to a specific host. As a result, when deployed over a mobile set of peers, hovering information than ”hovers” from host to host in order to remain attached to its location. This paper describes the hovering information concept and its characteristics, and…

Awards are non-material, extrinsic compensation taking the form of orders, medals, decorations and prizes. They have been widely used in monarchies and republics, private organizations, not-for-profit and profit-oriented firms. Nevertheless, they have so far not received much attention. This paper develops empirically testable hypotheses, analysing the determinants of the supply of…

This paper is concerned with the Lipschitzian behavior of the optimal set of convex semi-infinite optimization problems under continuous perturbations of the right hand side of the constraints and linear perturbations of the objective function. In this framework we provide a
sufficient condition for the metric regularity of the inverse of the optimal set mapping. This condition…
