An urban ecosystem is a dynamic system. Therefore, regular monitoring through the use of measurable indicators will enable an assessment of performance and effectiveness. This paper presents a conceptual framework to facilitate the development of an inclusive model for the sustainability assessment of green infrastructure. The framework focuses on key interactions between human health, ecosyste...

Current research in health informatics should provide the techniques and tools that will enable the development of an efficient hospital information ecosystem. The different information systems (IS) will be able to efficiently communicate with each other and provide a patient oriented environment. It is thus important to provide a clear understanding of this ecosystem during the analysis phase....

The forest rotations problem has been considered by generations of economists (Fisher, 1930; Boulding, 1966; Samuelson, 1976). Traditionally, the forest resource across all future harvest periods is assumed to grow without memory of past harvest periods. This paper integrates economic theory and intertemporal ecological mechanics, linking current harvest decisions with future forest growth, fin...

Vaccination is made possible by an interconnected and interdependent ecosystem of vaccine producers, vaccination policy makers and implementers, and vaccine procurers and funders. The future of vaccination depends on the continued health of this ecosystem and its ability to produce, purchase, deliver, and innovate. However, the number of vaccine producers that also do significant research and d...
