WHO's Fooling Who? The World Health Organization's Problematic Ranking of Health Care Systems [PDF]

open access: yes, 2008
The World Health Report 2000, prepared by the World Health Organization, presented performance rankings of 191 nations' health care systems. These rankings have been widely cited in public debates about health care, particularly by those interested in ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Integrated Delivery Networks: In Search of Benefits and Market Effects [PDF]

open access: yes, 2015
Integrated Delivery Networks (IDNs) have very different stated purposes than mere collections of hospitals: to coordinate care across the continuum of health services and to manage population health.

Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

open access: yesAdvanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...

Exploring the Potential of Zero‐Dimensional Carbon Nanomaterials in Photoluminescent, Electrochemiluminescent and Electrochemical Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical

Projecting health-care expenditure for Switzerland: further evidence against the 'red-herring' hypothesis [PDF]

open access: yes
This paper contributes to the debate about the impact of population ageing on health care expenditure. Some health economists claim that the commonly presumed impact of population ageing is a "red herring".
