Systems theory defines leverage points as places to intervene in order to change a system. Points with high impact on system behavior are notoriously hard to act upon, and indeed most policy intervention is based at the lowest level (#12 in Donella Meadows ...
The hydropower sector has recently raised the interest in pump as turbine (PaT) that can be a valid trade-off between capital cost and performance in micro-scale installations. Nevertheless, the modest efficiency of PaTs often restricts their exploitation. ...
Could deliberative democracy, and specifically citizens' assemblies be applied to engaging the broad population on public health? The experience of the Academic Citizens’ Assembly on climate and sufficiency is promising. How could this be adapted for impro ...
Can system theory help identify how to change our society towards wellbeing within the ecological constraint? In particular, can we link exergy to sufficiency action? ...
This paper analyzes efficiency and profitability in the Swiss banking sector over the period 1997–2019. We find strong evidence for scale economies: for most banks in the sample, efficiency and profitability increase with bank size. Using an instrumental v ...
Worst-case design is used in IoT devices and high performance data centers to ensure reliability, leading to a power efficiency loss. Recently, approximate computing has been proposed to trade off accuracy for efficiency. In this paper, we use Inexact Spec ...

Although the power conversion efficiency of perovskite solar cells (PSCs) has reached 25.7%, there is still great potential for improvement in their performance and stability. In the past few years, ionic liquids (ILs) have been extensively investigated an ...
Do we need more democracy? Our multiple crises, especially of biodiversity, climate, social inclusion, health, and ultimately purpose, all of them created (and still being made worse) by human action, show that our collective governance is failing to solve ...
Reducing CO2 emissions, restricting pesticides to protect health and biodiversity, enhancing corporate responsibility: why is Switzerland, one of the more democratic countries of the world, repeatedly failing to create a proper societal dialogue to face to ...
The influence of some coadsorbents and different pH values on the efficiency of DSS cells assembled with phycocyanin was evaluated using quartz crystal microbalance (QCM) and electrochemical techniques as impedance spectroscopy (EIS) and cyclic voltammetry ...
